Background: A large variety of methods have been developed to classify the foot based on structure and alignment. Foot line test is one among them use to find out the influence of load carriage and musculoskeletal injuries that may be associated with an increased vertical ground reaction force. It helps to understand that the position of the medial prominence of the navicular, in a Mediolateral direction, would provide additional relevant information describing the amount of pronation. The aim of this study is to find out the normative values of the foot line test in physiotherapy students and to find out its correlation with BMI and the correlation between foot length and height of physiotherapy students. Methods: It's a cross-sectional study in which 60 subjects are included with free of a foot injury and musculoskeletal problem to lower limb. With participants in the standing position the first MTP joint and navicular tuberosity were marked on the paper. The foot line test was drawn in MTP joint and navicular tuberosity. Results: Results show that normative values for the right foot were ranging from -5 to +8 while that for the left foot was ranging from 0 to 5in males. The normative values for the right foot were ranging -3 to +3 while that for the left foot was ranging from0 to 4 in females. The correlation between BMI and right foot was positively correlated for the left foot it was negatively correlated. Correlation between foot length and height is positively correlated. Conclusion: The study result shows that the normative value of males which is found to be ranging from -5 to 8 and for females ranging from 0 to 5. For left foot normative values for males is ranging from -3 to 4, and for females, its 0 to 4. Correlation of foot length and person height is positively correlated, and the correlation of BMI is positively correlated with the right foot, negatively correlate with the left foot

Full textAbstract:
This study aimed to investigate the concurrent validity between online evaluations (OEs) and face-to-face evaluations (IPEs) of a Senior Fitness Test and two balance tests in people with low back pain (LBP). Forty participants of 58.48 (9.87) years were included. The 30 s chair stand-up, arm curl, 2 min step, chair-sit and reach, back scratch, 8 foot up-and-go, sharpened Romberg, and one-legged stance tests were administrated using both OE and IPE methods. The results indicated no significant differences (p > 0.05) between the two methods except in the 8-foot up-and-go test (p = 0.007). Considering the ICC values and Bland-Altman plots, excellent agreement was found for the chair-sit and reach test, moderate agreement for the arm-curl and 8-foot up-and-go tests, and good agreement for the other tests. Strong correlations (p < 0.001) were observed in all variables except for the arm-curl and 8-foot up-and-go tests, where moderate correlations were found (p < 0.05). These results support the validity of OEs and IPEs in all tests, except for the arm-curl and 8-foot up-and-go tests, where lower ICC values and moderate correlations were found. However, it is important to consider the range of fluctuation of the ICC and the significant values obtained through correlations.

Full textAbstract:
The circadian rhythm of body core and surface temperature in 10 Comisana sheep kept under a natural photoperiod (06:30/19:00) was evaluated. Every 3 h for 24 consecutive hours rectal temperature (RT) and foot temperature were recorded. Particularly, foot temperature was recorded by infrared thermography, an ideal technique for evaluating the temperature not only at one point but also at the eight points as follows: in the right front of the interdigital area (FA1), in the left front of the interdigital area (FA2), in the right rear of the interdigital area (RA1), in the left rear of the interdigital area (RA2), in the right front of the interdigital line (FL1), in the left front of the interdigital line (FL2), in the right rear of the interdigital line (RL1) and in the left rear of the interdigital line (RL2). Two-way repeated measures ANOVA using SPSS, followed by Scheff&eacute;'s test, showed a significant effect of the time of day and side of temperature collection (P &lt; 0.05) on temperature values. The single cosinor procedure showed a daily rhythmicity of RT and foot temperature in all tested sides. The circadian oscillations of RT reflected the familiar circadian patterns of endogenous sources and the results of foot temperatures supported the idea that the daily rhythm was, at least in part, influenced by variation in the blood flow to the extremities. The infrared thermography providing more information on the development of disturbances in the peripheral circulation may be used with an advantage in occupational health examinations and in special clinical work.

In order to test the result of straight-line walking driven by simple cycloid foot trajectory, a kind of quadruped robot is proposed and Adams software is used to simulate the gait. According to the results, the shortage of simple cycloid foot trajectory is analyzed, that the unequal velocity of supporting feet was the key cause of feet-slippage and laterodeviation in the process of simulation. Thereby, the supporting phase of cycloid gait is smoothed, so that the phenomenon of differential in supporting legs is eliminated and the foot velocity is guaranteed to be continuous. After simulation again, the results show that feet-slippage and laterodeviation are solved.

Category: Midfoot/Forefoot Introduction/Purpose: The incompetence of both dynamic and static structures in the foot is responsible for acquired pes planus deformity. The aim of this study was to identify the anatomical location of the midfoot break in symptomatic pes planus deformity, and its relationship with other pes planus radiographic foot measurements. Methods: We completed the radiographic evaluation of 75 feet diagnosed with symptomatic pes planus. The break in the medial column line (Meary’s line) was measured on the lateral radiograph at the intersection of the anatomical axis of the talus and the first metatarsal. Pes planus measurements were performed on each the weight-bearing AP and lateral radiographs, including talonavicular coverage angle, talar – first/ second metatarsal angle, talar uncoverage, talocalcaneal angle, Meary’s angle line break, calcaneal and talar inclination, talocalcaneal angle, cuneiform - metatarsal, tarsal joints angles and distances. Due to Gaussian distribution, unpaired t-test and ANOVA tests were used. Results: The medial column line collapse was at the talonavicular joint in 77.3%, naviculocuneiform in 20%, and cuneiform metatarsal in 2.6%. The line angle severity was proportional to the talonavicular coverage angle and talar uncoverage (p 0.001, R2 0.4915 and P 0.003, R2 0.223). On comparison of the 3 line-break groups, the talocalcaneal angle was significantly higher when the line break was at talonavicular joint (P 0.001) although Meary’s angle was not significantly more severe. Conclusion: The apex of the medial column collapse occurs not only at the talonavicular joint but also distal to the spring ligament and tibialis posterior insertion. Foot abduction increases with the increase in the line collapse regardless of the breaking point. Talus flexion is worse if the arch collapse is at the talonavicular joint, suggesting incompetency of the spring ligament. Assessing the apex of deformity is essential to decide the correct operative strategy.

Full textAbstract:
Flat feet can cause a reduction in the foot function resulting in fatigue when walking or running. This condition can result in a suboptimal intensity exercise required to improve VO2Max of Pencak Silat athletes. This study aimed to determine the relationship between the shape of foot and VO2Max based on training duration among Pencak Silat athletes at the provincial level of DKI Jakarta. The study used a cross-sectional design involving 46 athletes selected through a total sampling. The subject criteria for this study included athletes aged 17-24 years, healthy, and had no lower extremities problems. The study utilized footprint test and multistage fitness test instruments. The study found that 27 (58.7%) athletes had a normal foot shape, while 19 (41.3%) had flat feet. There were no differences in age, sex, body mass index, and training duration between the two groups of foot shape (p 0.05). The maximum VO2 value was 45.0 (7.2) ml/kg/min in athletes with normal foot shape and 40.1 (70.5) ml/kg/min in athletes with flat feet. The independent t-test revealed a significant difference in VO2Max between the two groups of foot shapes (p = 0.028). The increase of VO2Max was in line with the duration of exercise, but this increase was not significant in subjects with flat feet compared to those with normal foot shape. It concludes that flat feet are negatively associated with VO2Max of athletes. Pencak Silat athletes with flat feet must exert extra effort to enhance their VO2Max, such as interval training and kinesio taping. Further research is recommended to explore the impact of these efforts on improving VO2Max.

Full textAbstract:
INTRODUCTION: The ankle–foot complex is the third most common site of pain in Indian dancers. In Bharatanatyam dance, rhythmic stamping performed barefoot at varying speeds may influence the height of the medial longitudinal arch, causing structural alteration of the ankle-foot complex. As little information is available on the ankle-foot complex of Bharatanatyam dancers, the present study was conducted to test the hypothesis that foot characteristics of Bharatanatyam dancers differ from those of non-dancers. METHODS: Female professional Bharatanatyam dancers (n=21), aged 18–30 years, with a minimum of 8 years of performance experience after completing formal dance training, and 21 control non-dancers participated in this study. Physical foot examination included navicular drop test and Feiss line. Foot geometry and pedobarography were recorded as participants walked barefoot at self-selected walking pace over a pressure-platform. An average of five gait cycles was computed to analyse maximum peak pressure (MPP), pressure time integral, contact time, and foot geometry of the midfoot, forefoot, great toe, and second to fifth toes. Analysis of covariance was performed for intergroup comparison of all variables with gait speed as a covariate. RESULTS: During walking, dancers presented a higher medial-longitudinal-arch, wider midfoot, and wider forefoot (cm) (p<0.001), indicating an over-pronated foot due to lower medial longitudinal arch height. Total plantar peak pressure (kPa) was 37% higher among dancers, whereas MPP was 24% higher on midfoot and 13% higher on forefoot, indicating greater plantar loading during walking. CONCLUSION: Greater plantar loading and an over-pronated foot during the most commonly performed weight-bearing activity of daily living (e.g., walking) explain the common prevalence of ankle and foot pain among dancers. These findings will inform clinicians and Bharatanatyam dancers on dancer’s foot function and guide strategies for prevention and management of foot pain.

Full textAbstract:
5-fluorouracil (5-FU) is one of the most commonly used antineoplastic drugs in the anticancer therapy. The hand-foot (HF) syndrome (palmar-plantar erythrodysesthesia) is an adverse effect frequently related to long-term i.v. administration of 5-FU or its orally applicable prodrug capecitabine. Its severity can even lead to interruption of the otherwise effective anticancer therapy. Tentative practice in some clinics has shown that topical application of 10% uridine ointment is beneficial for calming down the HF syndrome. This study is focused on verifying the alleged protective activity of uridine in thein vitromodel of cultured human keratinocyte cell line HaCaT. We also tested the protective effects of thymidine alone or uridine-thymidine combination. The cellular viability time progression was measured in order to evaluate the effect of protective agents by three different types of cytopathogenicity tests—NTCA test (non-destructive test of cellular activity), modified MTT test and RTCA (real-time cell analyser, Roche). All three methods proved the ability of uridine and uridine-thymidine combination to protect keratinocytes against 5-FU damagein vitro. While thymidine alone did not show any remarkable effect, the thymidine-uridine combination demonstrated enhanced protective activity compared to uridine alone. Our findings provided the supporting rationale for using uridine or uridine-thymidine ointments in the HF syndrome local therapy.

Purpose This study aimed to examine differences between track and field (T&F) runners and foot-orienteers (Foot-O) in the walking and running tests in the absence of vision and hearing. We attempted to determine whether experienced foot orienteers show better ability to maintain the indicated direction compared to track and field runners. Methods This study examined 11 Foot-O and 11 T&F runners. The study consisted of an interview, a field experiment of walking and running in a straight line in the absence of vision and hearing, and coordination skills tests. Results Participants moved straight min. 20 m and max. 40 m during the walking test and min. 20 m and max. 125 m during the running test and then they moved around in a circle. Significant differences between groups were found for the distance covered by walking. Differences between sexes were documented for the distance covered by running and angular deviations. Relationship between lateralization and tendencies to veer were not found. Differences were observed between Foot-O and T&F groups in terms of coordination abilities. Conclusions Participants moved in circles irrespective of the type of movement and experience in practicing the sport. Orienteers may use information about their tendencies to turning more often left or right to correct it during their races in dense forests with limited visibility or during night orienteering competition.

Full textAbstract:
Senecavirus A (SVA) is a member of the family Picornaviridae and enzootic in domestic swine. SVA can induce vesicular lesions that are clinically indistinguishable from Foot-and-mouth disease, a major cause of global trade barriers and agricultural productivity losses worldwide. The LF-BK αVβ6 cell line is a porcine-derived cell line transformed to stably express an αVβ6 bovine integrin and primarily used for enhanced propagation of Foot-and-mouth disease virus (FMDV). Due to the high biosecurity requirements for working with FMDV, SVA has been considered as a surrogate virus to test and evaluate new technologies and countermeasures. Herein we conducted a series of comparative evaluation in vitro studies between SVA and FMDV using the LF-BK αVβ6 cell line. These include utilization of LF-BK αVβ6 cells for field virus isolation, production of high virus titers, and evaluating serological reactivity and virus susceptibility to porcine type I interferons. These four methodologies utilizing LF-BK αVβ6 cells were applicable to research with SVA and results support the current use of SVA as a surrogate for FMDV.

Full textAbstract:
Palmar foot pain is an important chronic problem that impairs the abilities of sport horses. Though there are several research on different types of horses, there is a lack of information regarding polo horses, which are known for using in unique sport. Therefore, this research aimed to find the prevalence of palmar foot pain in polo ponies with forelimb lameness in Thailand. The horses included in this study were 30 Argentine polo ponies: 10 geldings and 20 mares, aged from 7 to 20 years old. All were barefoot and had not exercised for at least 2 months. The ponies underwent lameness examination procedures with subjective and objective evaluation, including a trot on a straight line, left and right lunging, a full forelimb flexion test and a toe wedge test. Close inspections of hoof conformation, hoof percussion and hoof testing were done before performing a palmar digital nerve block. The result showed that 25 (83.33%) of 30 polo ponies had forelimb lameness, which can be divided into 56.7% with unilateral forelimb lameness, and 26.7% with bilateral forelimb lameness. There were 17 (56.7%) polo ponies that responded positively to the full flexion test and 25 (83.33%) that responded positively to the hoof tester and percussion at the frog area. However, only 9 ponies (30%) were positive to palmar nerve block. In conclusion, this study reveals a notable incidence of forelimb lameness and palmar foot pain. Understanding palmar foot pain prevalence is vital for further equine health management.

Full textAbstract:
The nucleoside trifluridine/tipiracil (TAS-102) and the multikinase inhibitor regorafenib significantly improved survival in metastatic colorectal cancer patients (mCRC). Both treatments are characterized by different treatment-related adverse events but detailed analyses of predictive side effects are rare. In this retrospective, observational, real-life study, clinical data on mCRC patients treated with trifluridine/tipiracil or regorafenib at the Medical University of Vienna, Austria and the University Hospital Zurich, Switzerland were collected. The correlation between adverse events and response or survival rates were calculated performing Fisher’s exact test and log-rank test, respectively. Common adverse events of any grade included fatigue (52%), nausea/vertigo (34%), anemia (26%), and leukopenia (22%) in trifluridine/tipiracil patients and fatigue (42%), hand-foot-skin syndrome (36%) and hoarseness (34%) in patients upon regorafenib treatment. In trifluridine/tipiracil patients the prevalence of leukopenia (p = 0.044) and weight loss (p = 0.044) was prognostic, whereas leukopenia (p = 0.044) and neutropenia (p = 0.043) predicted PFS. The disease control rate was not significantly affected. In regorafenib-treated patients, the prevalence of nausea (p = 0.001) was prognostic, while oral mucositis predicted PFS (p = 0.032) as well as the DCR (p = 0.039). In conclusion, we underline the efficacy of trifluridine/tipiracil and regorafenib in the real-life setting. We describe predictive adverse events like neutropenia/leukopenia, which might be used as surrogate marker in anticancer therapy beyond second line treatment.

Aim and Objectives: The aim of this research to study the effect of hamstring tightness on Calcaneal Frontal Plane position and congruency of Medial Longitudinal Arch. The posterior compartment of the thigh, hip and knee joint comprise large muscle groups, including the semitendinosis, Semimembranosus and bicep femoris. These muscles are prone to tightness, which can lead to various musculoskeletaldisorders. Methods: A total 80 Subjects (40 Subjects in experimental group and 40 Subjects in control group) were recruited from undergraduates and postgraduate students of college. Experimental group has hamstring tightness and control group is present without hamstring tightness. Hamstring tightness is measured by Active knee extension test. Calcaneal Frontal Plane position and Congruency of medial longitudinal arch are the two component of Foot posture index. The rear foot was assessed via the inversion or eversion of the calacaneus. The posterior aspect of the calcaneus was visualized in line with the long axis of the foot. A pronated foot will demonstrate a more everted heel position and a supinated foot will exhibit a more inverted heel position.A pronated foot will demonstrate a low arch with flattening in the central position, where as a supinated foot will demonstrate a higher arch acutely angle toward the posterior portion.

Purpose: The purpose of this study was the analysis of foot load parameters and pain ion lumbar region after Hip Conditioning Program with Rotational Movements (HCP) and its influence on these parameters. Methods: The study included twenty-three middle-aged volunteers from Bialystok University of Technology (age: 49,43±11,88 years). During the first visit all participants were measured for each of the following components: height, weight and body mass index and all the participants completed written informed content the PAR-Q+ to identify potentially dangerous health conditions before the HCP. The assessment of foot load parameters and pain levels was conducted with Footwork Pro capacitive pressure measurement plate (Amcube, United Kingdom) and Standardised Nordic questionnaire about the occurrence of pain in lower back area before and after the HCP training regime. The collected data were processed with the Statistica 12 program (StatSoft Inc., United States). Footload parameters were examined with t-test for dependent samples and pain occurrence with Cochran Q test. Results: The results shows that HCP was effective and caused reduction in pain occurrence by 21,74% in lumbar spine region and better alignment of the foot load parameters in midfoot, lateral and overall foot region. Conclusion: It stands in line with other studies that HCP is effective and efficient way to help people who fights chronic low back pain. Increase in the pressure on the midfoot and lateral side of foot potentially reduce valgus of the ankle joint and lessen pressure on the longitudinal arch of the foot.

According to the available geological data and monitoring data, the completely weathered phyllite slope dilates and softens under the condition of continuous rainfall, which is then prone to instability failure. The indoor artificial rainfall test was carried out through the construction of the slope model, and the soil moisture sensor, pore water pressure sensor and matric suction sensor were used to study the variation laws of moisture content, pore water pressure and infiltration line at the back edge, slope body and the foot of the slope under continuous heavy rainfall. According to the sensor data and recorded information, with the influence of heavy rainfall over a long period of time, the water content and pore water pressure increased firstly, then decreased, and finally stabilized. The infiltration line moved from the top, the surface and the foot of the slope to the slope body, and shallow slip failure occurred in the shallow layer of the slope body.

Full textAbstract:
Background: This study aimed to analyze the functional results of cheilectomy in the surgical treatment of grade III hallux rigidus and to evaluate whether cheilectomy is a preferable first-line treatment over other surgical methods. Methods: Of 29 patients with moderate daily physical activity who underwent cheilectomy between 2009 and 2012 on being diagnosed as having grade III hallux rigidus according to the Coughlin-Shurnas grading system, 21 patients (14 women and 7 men; mean age, 59.2 years; age range, 52–67 years) (22 feet) with regular follow-up and complete medical records were included in the study. The patients were evaluated in the preoperative and postoperative periods using a visual analog scale for pain and the American Orthopaedic Foot and Ankle Society metatarsophalangeal assessment forms. Results: The preoperative mean American Orthopaedic Foot and Ankle Society score of 53 (range, 29–67) improved to 78 (range, 57–92) postoperatively (Wilcoxon test P = .001). The preoperative mean visual analog scale score of 89 (range, 60–100) improved to 29 (range, 0–70) in the postoperative period (Wilcoxon test P = .001). Conclusions: As a simple and repeatable procedure that allows for further joint-sacrificing surgical procedures when required, cheilectomy is a preferable method to be applied as a first-line option for the surgical treatment of grade III hallux rigidus.

Full textAbstract:
Background: Ankle-foot orthoses are usually used in combination with footwear. Shoe design can have a significant effect on kinematics of the lower limb joints and line of action of the ground reaction force during walking. But, ankle-foot orthosis–footwear combination is not appropriate for indoor barefoot walking in some Asian cultures. In this study, we have modified a solid ankle-foot orthosis in order to set it in the same position as a solid ankle-foot orthosis–footwear combination. Objective: To investigate the effect of a modified solid ankle-foot orthosis; a solid ankle-foot orthosis which can be locked in different positions on gait and balance performance in comparison with a conventional solid ankle-foot orthosis, a common solid ankle-foot orthosis–shoe combination in asymptomatic adults. Study Design: Cross sectional. Methods: Two standard solid ankle-foot orthoses were manufactured with the ankle joint in neutral position. Then, one of these solid ankle-foot orthoses was modified in order to allow locking in a different alignment. Walk across, limit of stability, and sit-to-stand tests of the balance master system were performed while participants wore the modified solid ankle-foot orthosis aligned in 5°–7° anterior inclination without a shoe and a conventional solid ankle-foot orthosis–shoe combination. Results: There was no significant change in walking speed, step length, and step width with the conventional and modified solid ankle-foot orthoses. In addition, movement velocity and maximum excursion of the center of gravity during the limit of stability test were not different, although the maximal forward excursion of the center of gravity was longer when wearing the modified solid ankle-foot orthosis compared to the conventional solid ankle-foot orthosis–shoe combination ( P = 0.000). Sway velocity of the center of gravity did not change during the sit-to-stand test. Conclusion: The results demonstrated that the modified solid ankle-foot orthosis had the same effects as the conventional solid ankle-foot orthosis–shoe combination on the gait and balance performance of asymptomatic adults. Clinical relevance The findings of the present study can be used as the basis for further investigations on the efficacy of the modified solid ankle-foot orthoses in different neuromuscular populations in order to help people who do not wear shoes at home, as is the custom in some Asian cultures.

The article deals with dynamic plantography, which is a popular diagnostic method focused on assessment of the foot condition during walking and to expose foot disorders. The aim of the paper is to discover whether it’s possible to do dynamic analyses on short platforms by using comparison of short and long sensory platform output. To get dynamic output were used ImportaMedica platforms, specific long platform Elegance and short platform Speed. Three subjects were involved in dynamic test on both platforms. The evaluated parameters were surface of the foot, maximum and average pressure, speed and gait line. By comparing these parameters the biggest difference was discovered in adapting walking because of the correct tread on short platform. When comparing the outputs from the long and short platforms, a longer duration of the right and left footsteps was recorded for all three subjects on the short platform.

Context: Decreased hamstring flexibility can lead to a plethora of musculoskeletal injuries, including low back pain, hamstring strains, and patellofemoral pain. Lack of flexibility may be the result of myofascial adhesions. The fascia connected to the hamstrings is part of the superficial back line that runs from the cranium to the plantar aspect of the foot. Any disruption along this chain may limit the flexibility of the hamstring. Objective: To investigate if self-myofascial release (SMR) of the plantar surface of the foot in addition to the hamstring group was more effective at improving the flexibility of the hamstrings when compared with either intervention alone. Design: Cross-over study. Setting: Athletic training facility. Participants: Fifteen college students (5 males and 10 females; age: 20.9 [1.4] y, height: 173.1 [10.3] cm, mass: 80.0 [24.9] kg) who were not older than 30, with no history of low back pain or injury within the past 6 months, no history of leg pain or injury within the past 6 months, no current signs or symptoms of cervical or lumbar radicular pain, no current complaint of numbness or tingling in the lower-extremity, and no history of surgery in the lower-extremity or legs. Interventions: Each participant received each intervention separated by at least 96 hours in a randomized order: hamstring foam rolling, lacrosse ball on the plantar surface of the foot, and a combination of both. Main Outcome Measures: The sit-and-reach test evaluated hamstring flexibility of each participant before and immediately after each intervention. Results: There were no significant differences found among the SMR techniques on sit-and-reach distance (F2,41 = 2.7, P = .08, ). However, at least 20% of participants in each intervention improved sit-and-reach distance by 2.5 cm. Conclusions: SMR may improve sit-and-reach distance, but one technique of SMR does not seem to be superior to another.

"For the detection of the flat foot and ligament laxity, the method of visual observation of the anatomical landmarks, the planogram on paper and the test of bearing body weight were used. At the same time, to test the stability of the ankle joint, we used the unipodal test on Bosu ball, where it was measured in seconds how much the subjects managed to maintain the unipodal position on Bosu ball. For the detection of low back pain, the method of individual interviewing of each athlete, the VAS scale of pain, the DLLT test (Double Leg Lowering Test) and the visual evaluation of any malalignments present in the bone structures was used. Applying the protocol for flat foot pathology, we obtained an improvement of the plantar arch in all subjects, as evidenced by the improvement of paper planograms where the decrease of the plantar footprint on the medial part of the foot was observed in all subjects of the experiment group. Compared to the standard protocol applied to the control group, we obtained by applying our protocol an improvement of the Achilles tendon line in orthostatic in 9 out of 10 subjects, while when applying the standard protocol, only 7 out of 10 subjects were observed. In conclusion, applying the kinetic protocol to recover post-training low back pain has improved low back pain, proving to be more beneficial than the standardized protocol for dancers, especially for female subjects.

Introduction. Postural abnormalities are considered as a public health problem. The aim of this study was to assess the frequency of body posture defects in girls and boys during early school period. Material and methods. The research covered 150 children, including 7-year-olds (25 girls; 25 boys), 8-year-olds (25 girls; 25 boys) and 9-year-olds (25 girls and 25 boys) attending randomly selected primary schools in the Podkarpackie Voivodeship, Poland. The body posture was assessed according to Kasperczyk’s scoring method. The Pearson Chi-square test, Mann Whitney U test, ANOVA Kruskal-Wallis test (with post hoc multiple comparisons test) were used to analyse the results. Results. Positioning of the shoulders (among 52% of children were positioned asymmetrically or slightly forward, in 15% of children were strongly asymmetrically moved forward, the top of the shoulders was located in front of the contour of the neck), the abdomen (54% of children had a bulging stomach, but not protruding beyond the chest line, 23% of children had a bulging belly, protruding beyond the chest line, and 1% of children had a sagging stomach), and the foot (40% of children had a flattened foot, 17% of children had a pes planus, and 9% of children had a pes planovalgus) concerned the greatest variation in the frequency of abnormalities. Associations were observed between sex of 7-year-olds and frequency of postural abnormalities (p = 0.025), as well as between age of the studied boys and frequency of postural abnormalities (p = 0.001). Conclusions. The shoulders, the abdomen, and the shape of the foot require special attention when taking and disseminating preventive and corrective actions. 7-year-old boys had worse body posture than 7-year-old girls, as well as 7-year-old boys obtained more penalty points than 9-year-old boys. This indicates the need for monitoring body posture and therapy, moreover this process should be characterized by continuity and mutual cooperation between therapists and the care and educational environment.

Full textAbstract:
The purpose of the study was to design and implement, in the physical and sports education process and in the motor evaluation process, a program of exercises and specific tests to optimize reaction time by using the Fitlight technological systems in relation to the manual and foot laterality of the pupils and identification of gender differences regarding the development of reaction speed. The study included 231 pupils, between 10 and 11 years old, who were divided into two groups according to gender, as follows: the male sample included 109 (97.32%) subjects, and the female sample included 103 (94.45%) participants. All subjects were identified with right manual and foot laterality. Both samples performed a specific exercise program to optimize reaction time in relation to manual and foot laterality by using Fitlight technologies. In the study, four tests were applied in order to evaluate reaction times using Fitlight, two in relation to the manual laterality and two with foot laterality, and the results were statistically processed with IBM SPPS Statistic 24 (IBM Corp., Armonk, NY, USA). Through the comparative analysis of the samples and the progress aimed at optimizing the reaction time specific to our study, it was found that the female sample recorded greater progress at the level of manual laterality, both for the right hand and for the left one, while the sample of boys recorded significant progress in terms of improving reaction time at the level of right and left foot laterality. At the foot laterality level, the results for the executions with the right foot were better in the simple test with four Fitlight spotlights in a line, and for the complex test, with eight Fitlight spotlights in a square, the results were better in the executions with the left foot. This reveals the fact that the greater the execution complexity, the better the motor prevalence on the left side.

Full textAbstract:
Introduction The use of free tissue transfers has overshadowed the much simpler approach of using simpler local rotation flaps for soft tissue coverage, especially in the foot and ankle. In this study, the authors aimed to examine the results of a single surgeon experience (CB) of the distally based reverse peroneus brevis muscle flap as the first line flap coverage for soft tissue coverage of the foot and ankle in medically high-risk patients who would otherwise require a major amputation. Methods All patients underwent Doppler examination only, prior to and intraoperatively prior to elevation of the distally based (reverse) peroneus brevis muscle flap; formal angiography or CT angiogram was not performed. The number of muscular perforators was documented intraoperatively as well as the defect size and location of flap inset. Patient demographics, medical risk factors for limb loss, mechanism of injury, the presence of soft tissue or bone infection, and wound size were recorded. The number of flap muscular perforators, flap complications, and donor site morbidity were recorded. Results Complete flap survival was observed in 75% of patients, while 14% experienced partial flap necrosis. Minor donor site morbidity was seen in 11% of patients. Complete flap necrosis occurred in 11% of patients. Smoking demonstrated to a statistically significant influence for partial/full flap failure (P = 0.0383, Fisher's exact test). Additionally, among patients with diabetes, an abnormally elevated hemoglobin A1c, which was defined as ≥6.5, consistent with the standard for uncontrolled diabetes, demonstrated a statistical association for a flap-related complication (P = 0.0170, Fisher's exact test). Overall, at a mean follow-up of 6.9 years, an 83% limb salvage rate was achieved. Failed limb salvage resulting in amputation was not necessarily due solely to a flap complication. Conclusions These data demonstrate that the distally-based reverse peroneus brevis muscle flap may be considered as a first line option for foot and ankle soft tissue coverage in the high-risk, multimorbid patient who is otherwise facing a major level amputation. The novelty lies in the patient population examined, specifically, high-risk, multimorbid patients with medium or large-sized soft tissue defects of the lower leg, foot and ankle.

Full textAbstract:
Due to rainfall infiltration, slope instability becomes frequent, which is the main reason for landslide disasters. In this study, the stability of slope affected by rainfall was analyzed using an indoor model test and geo-studio simulation method, and the variation law of phreatic line, seepage field, the most dangerous sliding surface, and safety factor with time were studied under rainfall infiltration. Research results showed that under the effect of rainfall, the slope failure presented a typical traction development mode. With the increase of time, the phreatic line of the slope kept rising, the water head keeps increasing, the seepage depth in the slope became deeper, and the slope stability worsened until the slope was damaged. The water head height decreased gradually from the slope left boundary to the right, and the water head width decreased gradually. The soil at the slope back edge was damaged, and the sliding soil accumulated at the slope foot, forming a gentle slope, which increased the shear strength of the slope, making the slope finally reach a stable state. In this process, the overlying soil changed from an unsaturated state to a saturated state, the pore water pressure and soil pressure increased, and then the slope was damaged, both of which decreased. Under high rainfall intensity, the slope was damaged, the soil in the slope was rapidly saturated, and the time required to produce the sliding area was short. When the rainfall intensity was the same, the smaller the slope angle was, the smaller the safety factor was. When the slope angle was the same, the greater the rainfall intensity was, the smaller the safety factor was.

Category: Ankle; Hindfoot; Lesser Toes; Midfoot/Forefoot Introduction/Purpose: Ankle limitation to dorsiflexion in an extended knee is observed during the second rocker of gait in patients with positive Silfverskiold test confirming an isolated gastrocnemius contracture (IGC). Tendons and muscles share intrinsic contractility and relaxation properties which can be modified during physiotherapy in comparison to the fascia which lacks it. The present study describes a case series of patients with positive Silfverskiold associated with various foot pathologies who underwent a selective fasciotomy of the postero-medial superficial portion of the crural fascia. The purpose of this study is to describe the surgical technique and clinical outcomes of this procedure. We hypothesize that this procedure can reach satisfactory clinical outcomes with the advantage of being a less invasive procedure. Methods: 26 patients treated with partial postero-medial superficial release (PMSR) of the crural fascia from January to October 2021 for IGC with associated chronic foot pain were included. Inclusion criteria considered patients with diagnosis of foot pain with IGC and positive Silfverskiold test. A transverse incision was made 2 cm distal to the flexion crease starting at the intermuscular line of the gastrocnemius muscle, 4 cm medially (Figure 1). Subcutaneous dissection was performed identifying the neurovascular bundle. A horizontal incision was performed to the superficial posterior fascia of the medial gastrocnemius head. The medial gastrocnemius muscle was not sectioned. Patients completed the FADI score previous to surgery and at final follow- up. Data was analyzed using SPSS 20. Paired samples T-tests were performed to identify significance of the difference in pain and function preoperatively and postoperatively with statistical significance set at p<0.05. Descriptive statistics were used for demographic variables. Results: 18 patients underwent partial PMSR of the crural fascia while 8 patients had additional procedures. Mean age of the included patients was 40.6 +/-18.5 years. Specifically, this included 4 feet with a diagnosis of metatarsalgia, 3 feet with metatarsalgia and plantar fasciitis, 6 feet with metatarsalgia, plantar fasciitis and cavus foot, 5 feet with plantar fasciitis, 3 feet with plantar fasciitis and insertional achilles tendinopathy, 4 patients with non-insertional achilles tendinopathy and 1 foot with flexor hallucis longus tendinopathy.The average ankle dorsiflexion increased significantly (p<0.0001) from -1.15 +/-2.15 degrees preoperatively to 10.65+/-2.02 degrees post-operatively. The average FADI score significantly increased (p<0.0001) from 47.54 +/-12.26 preoperatively to 80.46 +/-14.04 post-operatively. The average follow-up was 9.38 +/-3.76 weeks. All patients had a negative Silfverskiold test at final follow-up. Conclusion: Partial postero-medial superficial release (PMSR) of the crural fascia was found to be an effective outpatient procedure when used to relieve foot pain in those patients with an isolated gastrocnemius contracture. Patients who have failed conservative treatment can expect notable improvement with satisfactory FADI scores after the procedure. Future prospective studies should involve a larger number of patients with no additional procedures to be compared with gastrocnemius muscle release procedure for isolated gastrocnemius contracture with associated foot pain.

The knee-ankle-foot orthosis (KAFO) tool is commonly described for patients with a history of poliomyelitis and serves to improve gait and prevent degeneration of the knee joint. However, at present the effect of using knee ankle foot orthosis in monoplegia polio patients when walking has never been evaluated. The purpose of this study was to analyze biomechanical adaptation especially in spatiotemporal parameters and stability when the subjects walked with and without KAFO aids. Methods: Fifteen monoplegia subjects with poliomyelitis were tested with two gait analyzes (i.e. with and without KAFO aids). Spatiotemporal parameters were tested using the 10 Meter Walk Test (10MWT) instrument, while stability when running was tested with the Timed up and Go (TUG) test instrument. Data from the spatiotemporal parameters obtained were analyzed using paired T tests, and the McNemar test was used to analyze the stability variables while walking. Both analyzes will analyze differences in parameters tested when subjects are in line with and without KAFO tools. Significant level used is p <0.05. Results: The results showed that there were significant differences in spatiotemporal parameters and stability when subjects walked with and without KAFO aids. This tool increases spatiotemporal parameters and stability when the subject runs using KAFO compared to when they did not use orthosis at all. When the stance phase in the leg is paralysis, hyperextension in the knee and excessive flexion of the knee is reduced, while flexion in the hip joint increases. Walking stability increased in 60% of subjects when they used KAFO when walking. This study found that gait compensation was also reduced when subjects walked using KAFO, and through direct feedback the subject stated that walking using KAFO made them not easily tired and could go further.

Full textAbstract:
Diabetic foot is a serious complication that poses significant risks for diabetic patients. The resulting reduction in protective sensitivity in the plantar region requires early detection to prevent ulceration and ultimately amputation. The primary method employed for evaluating this sensitivity loss is the 10 gf Semmes–Weinstein monofilament test, commonly used as a first-line procedure. However, the lack of calibration in existing devices often introduces decision errors due to unreliable feedback. In this article, the mechanical behavior of a monofilament was analytically modeled, seeking to promote awareness of the impact of different factors on clinical decisions. Furthermore, a new device for the automation of the metrological evaluation of the monofilament is described. Specific testing methodologies, used for the proposed equipment, are also described, creating a solid base for the establishment of future calibration guidelines. The obtained results showed that the tested monofilaments had a very high error compared to the 10 gf declared by the manufacturers. To improve the precision and reliability of assessing the sensitivity loss, the frequent metrological calibration of the monofilament is crucial. The integration of automated verification, simulation capabilities, and precise measurements shows great promise for diabetic patients, reducing the likelihood of adverse outcomes.

ABSTRACT Objective: The medial longitudinal arch is the main structure of load bearing and shock absorption of the foot. The evaluation of medial longitudinal arch, such as the navicular height, the medial longitudinal arch angle and the Feiss line should be performed with the subtalar joint in the neutral and relaxed position. Our study analyzed the correlation between the measurements of the subtalar joint in neutral and relaxed positions during the evaluation tests of the medial longitudinal arch. Methods: This is a cross-sectional study, in which 51 healthy volunteers (102 feet; 36 women; 28 ± 5 years, 1.66 ± 0.10 m; 24.5 ± 4.5 kg/m2) had their navicular height, medial longitudinal arch angle and Feiss line measured in the neutral and relaxed positions. The correlation between the measures was evaluated using Pearson’s test. Results: A strong correlation of the 102 feet Feiss line measurements between neutral and relaxed positions (r = 0.81) was observed, and a moderate correlation between the medial longitudinal arch angle (r = 0.78) and between navicular height in neutral and relaxed positions (r = 0.76). Conclusion: The measurements of the longitudinal medial arch between the neutral and relaxed positions are strongly correlated. Therefore, it is not necessary to measure the medial longitudinal arch in both neutral and relaxed positions. Level of Evidence II, Diagnostic Studies - Investigating a diagnostic test.

Abstract The airborne LiDAR uses the aircraft as the observation platform, requiring the aircraft to keep a uniform speed and a straight-line cruise state, to obtain more accurate ranging information and a uniform laser foot point distribution cloud picture. Atmospheric turbulence is the main atmospheric disturbance that affects the aircraft movement in the cruise state, which can lead to a serious decrease in radar ranging accuracy and the distortion of cloud point distribution. In this paper, the motion error caused by atmospheric turbulence during flight is studied. The real-time simulation method based on the six degrees of freedom flight mechanics equation is used to establish the motion law of the carrier under atmospheric turbulence. The method’s reliability is verified by comparing it with flight test data. Then, the foot point distribution cloud image and ranging error of airborne LiDAR under different wind field intensities are simulated by real-time simulation of six degrees of freedom. The error law of radar motion affected by atmospheric turbulence is obtained.

The neutral foot position of the prosthetic SACH foot has a higher heel surface from the front of the foot (metatarsal line) with 1cm heel height. The prosthesis will be aligned to match the shoes that patient will use. When the patient is using shoes, the prosthetic SACH foot will be placed in a neutral position and will be supported by the shoe. When the patient does not use the shoe, the prosthesis will tilt backward especially when the foot is mid-stance and will force the pressure of the knee toward the extension of the knee joint which can cause damage to the knee joint structure. Therefore, knee joints will be measured at the time of the patient's use and not wearing shoes during mid-stance. Objective: To find out if there are significant differences in knee joint degree during mid-stance when using and not using shoes with 1cm heel height. Methods Quantitative comparative by observation of 2-dimensional motion in transtibial amputation patients using shoes and not using shoes with cross-sectional study design. Result : The degree of knee joints generated during mid-stance by patients with transtibial amputation when using shoes was 10.8o of flexion (p = 0.004) while at the time of not using the resulting knee boots was 4.5o of flexion (p = 0,000), normal degree of knee joint during mid- stance is 10o-20o of flexion. The results of paired t-test showed that there were significant differences in knee joint degree from standard degree, but when using the shoe showed a result of 0.8o larger than the lowest normal range while when not using shoes the resulting degree of 6.3o is smaller than lowest normal range.

Abstract. This article introduces a new fully automated FTIR system that is part of the Total Carbon Column Observing Network. It will provide continuous ground-based measurements of column-averaged volume mixing ratio for CO2, CH4 and several other greenhouse gases in the tropics. Housed in a 20-foot shipping container it was developed as a transportable system that could be deployed almost anywhere in the world. We describe the automation concept which relies on three autonomous subsystems and their interaction. Crucial components like a sturdy and reliable solar tracker dome are described in detail. First results of total column measurements at Jena, Germany show that the instrument works well and can provide diurnal as well as seasonal cycle for CO2. Instrument line shape measurements with an HCl cell suggest that the instrument stays well-aligned over several months. After a short test campaign for side by side intercomaprison with an existing TCCON instrument in Australia, the system will be transported to its final destination Ascension Island.

Full textAbstract:
The zero-velocity update (ZUPT)-aided extended Kalman filter (EKF) is commonly used in the traditional inertial navigation system (INS)-based foot-mounted pedestrian dead reckoning (PDR) system, which can effectively suppress the error growth of the inertial-based pedestrian navigation systems. However, in the realistic test, the system still often suffers from drift, which is commonly caused by two reasons: failed detection of the stationary phase in the dynamic pedestrian gait and heading drift, which is a poorly observable variable of the ZUPT method. In this paper, firstly, in order to improve the initial heading alignment accuracy, a novel method to calibrate the PDR system’s initial absolute heading is proposed which is based on the geometric method. By using a calibration line rather than only using the heading of the starting point, the method can calibrate the initial heading of the PDR system more accurately. Secondly, for the problem of failed detection of the stationary phase in the dynamic pedestrian gait, a novel stationary phase detection method is proposed, which is based on foot motion periodicity rather than the threshold comparison principle in the traditional method. In an experiment, we found that the zero-speed state points always occur around the minimum value of the stationary detector in each gait cycle. By taking the minimum value in each gait cycle as the zero-speed state point, it can effectively reduce the failed detection of the zero-speed interval. At last, in order to reduce the heading drifts during walking over time, a new motion constraint method is exploited based on the range constraint principle. During pedestrian walking, the distance between the foot position estimates of the current moment and the previous stationary period is within the maximum stride length. Once the distance is greater than the maximum stride length, the constraint method is used to confine the current estimated foot position to the sphere of the maximum stride length relative to the previous stationary foot position. Finally, the effectiveness of all proposed methods is verified by the experiments.

Aims The aim of this study was to examine the effects of gender on the relationship between Functional Movement Screen (FMS) and treadmill-based gait parameters. Methods Twenty elite junior athletes (10 women and 10 men) performed the FMS tests and gait analysis at a fixed speed. Between-gender differences were calculated for the relationship between FMS test scores and gait parameters, such as foot rotation, step length, and length of gait line. Results Gender did not affect the relationship between FMS and treadmill-based gait parameters. The nature of correlations between FMS test scores and gait parameters was different in women and men. Furthermore, different FMS test scores predicted different gait parameters in female and male athletes. FMS asymmetry and movement asymmetries measured by treadmill-based gait parameters did not correlate in either gender. Conclusion There were no interactions between FMS, gait parameters, and gender; however, correlation analyses support the idea that strength and conditioning coaches need to pay attention not only to how to score but also how to correctly use FMS.

Purpose: To evaluate the influence of different arm postures from the physiological standing position using force plate analysis of the gravity line. Methods: Forty healthy volunteered university students were enrolled. Each subject assumed different standing positions including standing with arms resting on the side (control), with fist over the clavicle (clavicular position), with active shoulder flexion in 30°, 60° and 90° with elbows extended (active flexion A), with hand rest on a bar with a static support (passive flexion P), and with hand rest on a bar with a drip stand (passive flexion D). The offset of the gravity line from the heel was measured by force plate analysis. The offset of the gravity line in different arm positions was compared with the control using paired t-test. Results: The mean anterior offset of the gravity line in control position is 39.80% of the foot length. All testing positions showed anterior shift of the gravity line compared with the control position from 0.51% to 7.50%. There were statistically significant changes of the gravity line from the control position in all ( p < 0.05), except in the clavicular position ( p = 0.249). Conclusion: All testing positions cause anterior shifting of the center of gravity from the physiological standing position. Clavicular position is the best comparable posture to the physiological standing position in taking a lateral radiograph. We recommend using the clavicular position as the standard testing position in the assessment of the sagittal profile.

Abstract Objectives The use of MR-imaging is recommended for the early detection of RA. Next to the small joints of the hands, foot-joints are often involved. Therefore, imaging inflammation of the feet in addition to hands may be informative, but prolongs scan-time and leads to additional costs. We studied the value of MRI of the feet alone and complementary to MRI of the hands in patients with clinically suspect arthralgia (CSA). Methods 357 consecutively included CSA patients underwent contrast-enhanced 1.5 T-MRI of hand (MCP2-5 and wrist) and foot (MTP1-5) joints at baseline. Scans were scored for synovitis, osteitis and tenosynovitis. After ⩾1 year follow-up, the development of clinically apparent inflammatory arthritis (IA) was studied. Cox regression was performed and test characteristics were evaluated. Sensitivity analyses were performed for the outcome RA-development (2010-criteria). Results MRI-detected tenosynovitis of the feet was associated with IA-development, independently from synovitis and osteitis hazard ratio (HR) (95%CI) 4.75 (2.38; 9.49), and independently from ACPA and CRP, HR 3.13 (1.48; 6.64). From all CSA patients, 11% had inflammation in hands and feet, 29% only in hands and 3% only in feet. In line with this finding, the addition of MRI-feet to MRI-hands did not increase the predictive accuracy; the sensitivity remained 77%, while the specificity decreased from 66% to 62%. Sensitivity analyses with RA development as outcome showed similar results. Conclusion Tenosynovitis at the forefeet in CSA predicted IA and RA development. Addition of foot MRI to hand MRI did not increase the accuracy. Foot MRI can be omitted to reduce scan time and costs and increase the feasibility.

Full textAbstract:
Walking is the most basic form of human activity for achieving mobility. As an essential function of the human body, the examination of walking is directed towards the assessment of body mechanics in posture and during movement. This work proposes a wearable smart system for the monitoring and objective evaluation of foot biomechanics during gait. The proposed solution assumes the cross-correlation of the plantar pressure with lower-limb muscular activity, throughout the stance phase of walking. Plantar pressure is acquired with an array of resistive pressure sensors deployed onto a shoe insole along the center of gravity progression line. Lower-limb muscular activity is determined from the electromyogram of the tibialis anterior and gastrocnemius lower limb muscles respectively. Under this scenario, physiological gait assumes the interdependency of plantar pressure on the heel area with activation of the tibialis anterior, as well as plantar pressure on the metatarsal arch/toe area with activation of the gastrocnemius. As such, assessment of gait physiology is performed by comparison of a gait map, formulated based on the footprint–lower-limb muscle cross-correlation results, to a reference gait template. A laboratory proof of concept validates the proposed solution in a test scenario which assumes a normal walking and two pathological walking patterns.

AbstractDetermination of the 3He isotope is important to many fields of astrophysics, including stellar evolution, chemical evolution, and cosmology. The isotope is produced in stars which evolve through the planetary nebula phase. Planetary nebulae are the final evolutionary phase of low- and intermediate-mass stars, where the extensive mass lost by the star on the asymptotic giant branch is ionised by the emerging white dwarf. This ejecta quickly disperses and merges with the surrounding ISM. 3He abundances in planetary nebulae have been derived from the hyperfine transition of the ionised 3He, 3He+, at the radio rest frequency 8.665 GHz. 3He abundances in PNe can help test models of the chemical evolution of the Galaxy. Many hours have been put into trying to detect this line, using telescopes like the Effelsberg 100m dish of the Max Planck Institute for Radio Astronomy, the National Radio Astronomy Observatory (NRAO) 140-foot telescope, the NRAO Very Large Array, the Arecibo antenna, the Green Bank Telescope, and only just recently, the Deep Space Station 63 antenna from the Madrid Deep Space Communications Complex.

1053 Background: ABX and XEL both have substantial single agent activity in MBC. Taxane and anti-metabolite doublets improve response rate and TTP and longer survival. ABX administered weekly has an excellent safety and efficacy profile with maintenance of dose intensity. This study was designed to test the safety and efficacy of ABX + XEL given in a novel combination schedule. Methods: This phase II, multicenter open label study utilized ABX 125 mg/m2 IV on day 1, 8 and with no premeds and capecitabine 825 mg/m2 PO BID days 1–14 on a Q 3 week cycle. The primary endpoint is objective response rate, with evaluation performed after every 2 cycles. Entry criteria include measurable MBC by RECIST criteria, age >18, PS 0–2, no prior chemo for metastatic disease, > 6 months since adjuvant fluoropyrimidine and/or paclitaxel. Results: The full sample of 50 patients (pts) have been enrolled; data from 43 pts are available for analysis. Median age is 58 (range 23.7–90.6). 37% received prior adjuvant anthracycline and 33% prior adjuvant taxane. Median number of metastatic sites is 2 (range 1–7), with most common sites of disease liver, 53.5%; bone, 51.2%; and lung, 14%. 226 cycles of therapy have been delivered. 5 pts required a dose reduction in XEL (3 pts to 650 mg/m2; 2 to 550 mg/m2) and 4 pts had dose reduction in ABX to 100 mg/m2. XEL dose reductions occurred due to hand-foot syndrome (3), neutropenia (1), and fatigue (1). ABX dose reductions occurred due to mucositis, diarrhea, fatigue, and neuropathy (1 pt each). 10 pts had grade 3–4 non-hematologic AEs: 3 hand-foot syndrome, 4 fatigue, and 3 GI. Hematologic AEs included 4 with grade 3 and 1 with grade 4 neutropenia, and 2 with grade 4 febrile neutropenia. The most common AEs of any grade were GI (30), dermatological (23), fatigue (15), neuropathy (12), and hand-foot syndrome (11). The incidence of Grade 1–2 neuropathy was 25% (no grade 3–4).

Publications were classified according to the type, language, subject area, source title, author, affiliation, and country/territory. The documents were grouped later into thematic topics. The diseases evaluated in each study were quantified separately and in related groups, and distributed by decades. The frequencies of the thematic topics and diseases were compared by the chi-square test for adherence. In total, 642 publications were analyzed (595 articles, 46 reviews, and 1 note). Most of these papers were written in English (518). The main subject areas were Veterinary; Agricultural and Biological Sciences; and Biochemistry, Genetics, and Molecular Biology. Journal of Dairy Science was the journal that published most articles in the area, with the best citations (SCImago Journal Rank = 1.21). The authors with the highest number of publications were Johann Kofler with 19, and David Nixon Logue and Jan Keith Shearer with 18 documents each. By affiliation, the institution with the highest number of publications was the Swedish University of Agricultural Sciences. By country or territory, the United States of America (22%), the United Kingdom (17%), Germany (11%), and Canada (10%) together accounted for 60% of the publications. The classification of the documents into thematic topics resulted in four groups: Specific hoof diseases (70%), General hoof diseases (14%), Lameness (11%), and Healthy hoof characterization (5%). Eighteen foot and claw diseases have been studied, with the following being the most frequent: digital dermatitis (17%), sole ulcer (15%), and white line disease (11%).

271 Background: Within the last 4 years, the FDA approved five drugs as second-line therapies for advanced HCC. At our cancer center, the majority of our patients are Hispanic with varying liver dysfunction, and this real world population is not represented in registration trials of TKIs and IOs. Therefore, we analyzed survival and toxicities among second-line therapies for HCC at our Hispanic-majority NCI-designated cancer center. Methods: Retrospective analysis of patients with advanced HCC diagnosed at Mays Cancer Center from 1/2015-3/2019 who received second-line therapies, including IO (i.e. nivolumab), TKIs (i.e. cabozantinib, regorafenib), or hospice/best supportive care (BSC). Progression-free survival (PFS) was determined using Kaplan-Meier method, and hazard ratios estimated with Cox proportional hazards model. AEs according to Common Terminology Criteria for AEs v5.0 were analyzed with Fisher’s exact test. Results: Of the patients receiving first-line therapy, the median age was 60 years (n=65), and patients were 75% (n=49) Hispanics. 58 (89%) patients went onto receive second-line therapy. Child-Pugh (CP) score: A 17%, B 55%, C 28%. Median PFS was 3.1 months with TKI (n=6), 3.3 months with IO (n=27), and 1.3 months with BSC (n=25) (Table). There was improved survival with IO when compared to BSC (HR=3.26; 95% CI: 1.58-6.72; p=0.00136). There was no significant difference when comparing IO to TKI (HR=0.94; 95% CI: 0.31-2.86; p=0.92), but a trend to improved PFS with TKI when compared to BSC (HR=3.08; 95% CI: 0.96-9.84; p=0.06). TKI group had significantly more rash (p=0.01) and hand-foot syndrome (HFS) (p<0.001) compared to IO and BSC. All other AEs demonstrated no significant difference between groups (Table). Conclusions: In our Hispanic-majority cohort, patients with varying liver dysfunction, including CP B & C cirrhosis, were more likely to receive IO or BSC. Both second-line treatment groups (IO or TKI) had increased mPFS compared to BSC. Both IO and TKI groups were tolerable compared to BSC, with expected toxicity per class of drug. More prospective studies comparing second-line agents should be done in patients with varying liver dysfunction to understand survival, tolerability, and quality of life. [Table: see text]

Full textAbstract:
Category: Basic Sciences/Biologics, Hindfoot Introduction/Purpose: Sinus Tarsi syndrome is a frequent cause of anterolateral foot pain following injury. Chronic lateral subtalar pain, often referred to as “Sinus Tarsi Syndrome”, is commonly reported to occur following trauma. One hypothetical epidemiological predisposing factor for sinus tarsi syndrome is flatfoot deformity with valgus hind foot alignment. Common conservative treatment includes medial heel posting to attempt to widen the sinus tarsi space and alleviate synovitic pain. Although treatment with operative intervention has been reported, no data exists to evaluate if hindfoot realignment functionally opens the sinus tarsi volume. Methods: Weight-bearing Computed Tomography (CT) scans were obtained in 5 healthy volunteers standing at rest on slanted platforms, 25 degree valgus and 25 degree varus. The volume of the sinus tarsi was measured on each scan. Cross sectional area of the sinus tarsi was measured in 3.6 mm slices from the most lateral fully enclosed image to the most lateral aspect of the middle facet of the subtalar joint. Area measurements were multiplied by cut depth (3.6 mm) and summed. Critical angle distance was measured as a straight line from the most lateral point of the lateral process of the talus to the base of the critical angle of Gissane. Subfibular distance was then measured from the most distal tip of the fibula in a straight line to the nearest point of the lateral calcaneal wall. Data were compared using a one way ANOVA and Tukey’s multiple comparison test. Results: The mean sinus tarsi volume in the valgus position was 325.1 mm3 (±88) and 313.3 (±71) for the left and right foot, respectively. In the varus position, the mean sinus tarsi volume increased to 646.8 mm3 (±169) and 599 mm3 (±203). There was a significant difference between the varus and valgus position for both feet (left p<0.01 / right p<0.05). The critical angle distance increased from 28.1 mm (±7.5) to 91.3 mm (±26) for the left foot and 26.3 mm (±7.6) to 87 mm (±27.9) for the right foot when realigned to the varus position (p<0.0001). There was not a significant increase in the sub fibular distance when repositioned from valgus to varus (p=0.06 / p=0.35). Conclusion: This study confirms that moving from a valgus to a varus position significantly increases the volume of the sinus tarsi as well as significantly increases the distance from the lateral process of the talus to the calcaneal angle of Gissane. Interestingly, subfibular distance did not significantly increase, although this may reach significance with increased samples. With confirmation that adjusting hindfoot positioning impacts lateral osseous impingement, future studies are warranted to correlate these findings with clinical symptoms.

Abstract. This article introduces a new fully automated FTIR system that is part of the Total Carbon Column Observing Network (TCCON). It will provide continuous ground-based measurements of column-averaged volume mixing ratio for CO2, CH4 and several other greenhouse gases in the tropics. Housed in a 20-foot shipping container it was developed as a transportable system that could be deployed almost anywhere in the world. We describe the automation concept which relies on three autonomous subsystems and their interaction. Crucial components like a sturdy and reliable solar tracker dome are described in detail. The automation software employs a new approach relying on multiple processes, database logging and web-based remote control. First results of total column measurements at Jena, Germany show that the instrument works well and can provide parts of the diurnal as well as seasonal cycle for CO2. Instrument line shape measurements with an HCl cell suggest that the instrument stays well-aligned over several months. After a short test campaign for side by side intercomaprison with an existing TCCON instrument in Australia, the system will be transported to its final destination Ascension Island.
