Abstract:

In order to solve the problem of field fault detection for engineering vehicle, we introduce a new networked portable fault diagnostic system based on PDA. The architecture of the system is presented. The system consists of dual-tier architecture. The first tier server is based on the related technical database of engineering vehicles, and the second tier one is the technical information database downloaded from the manufactures technical resources with PDA as the terminal for maintenance technician. The system function includes information query, user interaction, data downloading and uploading as well as network communication. The software platform is composed of Microsoft SQL Server Compact (SQL CE) database, application software on PDA and computer. Meanwhile the hardware platform is mainly composed of desktop PC or dedicated server, PDA mounted with cradle, data acquisition card as well as PCMCIA network adapter and so on. Both wireless communication and USB interface are adopted in the system. It has been used in many military units. The application demonstrates that the PDA-based networked fault diagnosis system of vehicles is beneficial to data query, fault elimination and repair capability of engineering vehicles.

Abstract:

The presence of cardiac pacemakers and defibrillators complicates making end-of-life (EOL) medical decisions. Palliative care/medicine consultation (PCMC) may benefit patients and primary providers, but data are lacking. We retrospectively reviewed 150 charts of patients who underwent device deactivation at our tertiary care center (between November 1, 2008, and September 1, 2012), assessing for PCMC and outcomes. Overall, 42% of patients received a PCMC, and 68% of those PCMCs specifically addressed device deactivation. Median survival following deactivation was 2 days, with 42% of deaths occurring within 1 day of deactivation. There was no difference in survival between the groups. The EOL care for patients with implanted cardiac devices is complex, but PCMC may assist with symptom management and clarification of goals of care for such patients.

Abstract:

The immobilization of enzymes using protein coated micro-crystals (PCMCs) was reported for the first time in 2001 by Kreiner and coworkers. The strategy is very simple. First, an enzyme solution must be prepared in a concentrated solution of one compound (salt, sugar, amino acid) very soluble in water and poorly soluble in a water-soluble solvent. Then, the enzyme solution is added dropwise to the water soluble solvent under rapid stirring. The components accompanying the enzyme are called the crystal growing agents, the solvent being the dehydrating agent. This strategy permits the rapid dehydration of the enzyme solution drops, resulting in a crystallization of the crystal formation agent, and the enzyme is deposited on this crystal surface. The reaction medium where these biocatalysts can be used is marked by the solubility of the PCMC components, and usually these biocatalysts may be employed in water soluble organic solvents with a maximum of 20% water. The evolution of these PCMC was to chemically crosslink them and further improve their stabilities. Moreover, the PCMC strategy has been used to coimmobilize enzymes or enzymes and cofactors. The immobilization may permit the use of buffers as crystal growth agents, enabling control of the reaction pH in the enzyme environments. Usually, the PCMC biocatalysts are very stable and more active than other biocatalysts of the same enzyme. However, this simple (at least at laboratory scale) immobilization strategy is underutilized even when the publications using it systematically presented a better performance of them in organic solvents than that of many other immobilized biocatalysts. In fact, many possibilities and studies using this technique are lacking. This review tried to outline the possibilities of this useful immobilization strategy.

Abstract:

Abstract Introduction The Veterans Health Administration (VHA) is a national leader in integrated care, known in the VHA as the Primary Care Mental Health Integration (PCMHI) model. This model is associated with improved quality of services and same-day access for veterans. There has been some recent development of PCMHI/integrated care competencies within VHA and across the nation. To fully implement these competencies, however, PCMHI providers must not only be trained, but their adherence to the PCMHI model must also be assessed. While there have been recent advances, there has been little research that has examined the adherence of PCMHI providers to the model or methods to improve adherence. Materials and Methods The present study sought to examine and improve the clinical practice of a team of eight PCMHI providers to make practice more adherent to the PCMHI model. This study was conducted at a large Midwestern VA Medical Center using interventions based in assessment, feedback, and training—measured at three points in time. The Primary Care Behavioral Health Provider Adherence Questionnaire (PPAQ; Beehler GP, Funderburk JS, Possemato K, et al.: Psychometric assessment of the primary care behavioral health provider adherence questionnaire (PPAQ). Transl Behav Med 2013; 3: 379–91.) was used to assess provider adherence and the PPAQ toolkit was used to provide tailored recommendations for improving provider practice. In addition, the VHA “Foundations Manual” and Functional Tool outlined essential behavioral targets that are consistent with the PCMHI model and the “essential provider behaviors” from the PPAQ. A combination of individual and group interventions was presented and adherence, pre and post, was assessed with the PPAQ and with evaluation of clinical practice data. Results Results indicated that the behavior of PCMHI providers changed over time, with providers exhibiting more PCMHI consistent behaviors and fewer inconsistent behaviors. Adherence to the PCMHI model increased. Conclusion Providing assessment, feedback, and training in the PCMHI model changed the clinical practice of PCMHI providers and resulted in improved adherence. Clinical and research implications are discussed.

Abstract:

Oxidant stress alters protein structure and function, possibly through the modification of the redox status of regulatory protein sulfhydryl groups. We used the sulfhydryl-blocking reagent p-chloromercuriphenylsulfonic acid (pCMPSA), applied selectively and independently to either the intracellular or extracellular environment, to study the relationship between blocking protein sulfhydryl groups and Na(+)-K+ pump current (i.p.). In guinea pig ventricular myocytes voltage clamped at -30 mV, extracellular pCMPSA (50, 100, and 400 microM) caused a concentration-dependent reduction in holding current. The selective intracellular administration of pCMPSA (100 microM) induced a similar inhibition of i.p., albeit over a longer time course. The inhibition of ip resulting from either the intracellular or extracellular application of pCMPSA (100 microM) was reversed, in part, by the extracellular application of dithiothreitol (3 mM). An intracellular oxidant stress was also imposed by using diethyl maleate to deplete the intracellular nonprotein sulfhydryl content [represented by reduced glutathione (GSH)]. In myocytes isolated from diethyl maleate-treated guinea pigs *860 mg/kg i.p., 30 min before study), intracellular GSH was depleted by 93% and i.p. was depressed by 38% at all membrane potentials tested. We propose that Na(+)-K+ pump function may be related to protein and nonprotein sulfhydryl status. Protein sulfhydryl oxidation and glutathione depletion may account, in part, for a depression in Na(+)-K+ pump activity during reperfusion-induced oxidant stress.

Abstract:

Abstract. The dynamics of biochemical processes in terrestrial ecosystems are tightly coupled to local meteorological conditions. Understanding these interactions is an essential prerequisite for predicting, e.g. the response of the terrestrial carbon cycle to climate change. However, many empirical studies in this field rely on correlative approaches and only very few studies apply causal discovery methods. Here we explore the potential for a recently proposed causal graph discovery algorithm to reconstruct the causal dependency structure underlying biosphere–atmosphere interactions. Using artificial time series with known dependencies that mimic real-world biosphere–atmosphere interactions we address the influence of non-stationarities, i.e. periodicity and heteroscedasticity, on the estimation of causal networks. We then investigate the interpretability of the method in two case studies. Firstly, we analyse three replicated eddy covariance datasets from a Mediterranean ecosystem. Secondly, we explore global Normalised Difference Vegetation Index time series (GIMMS 3g), along with gridded climate data to study large-scale climatic drivers of vegetation greenness. We compare the retrieved causal graphs to simple cross-correlation-based approaches to test whether causal graphs are considerably more informative. Overall, the results confirm the capacity of the causal discovery method to extract time-lagged linear dependencies under realistic settings. For example, we find a complete decoupling of the net ecosystem exchange from meteorological variability during summer in the Mediterranean ecosystem. However, cautious interpretations are needed, as the violation of the method's assumptions due to non-stationarities increases the likelihood to detect false links. Overall, estimating directed biosphere–atmosphere networks helps unravel complex multidirectional process interactions. Other than classical correlative approaches, our findings are constrained to a few meaningful sets of relations, which can be powerful insights for the evaluation of terrestrial ecosystem models.

Abstract:

Abstract Introduction: The purpose of this review is to evaluate the direct delivery of health care to veterans before and after incorporating clinical pharmacy services within primary care mental health integration (PCMHI) at the Tuscaloosa Veterans Affairs Medical Center. Prior to establishing the role of the clinical pharmacy specialist (CPS) within PCMHI, the primary care providers deferred all mental health assessments to specialty mental health. As the demands of the service grew exponentially, assistance from clinical pharmacy was critical. Methods: A randomized, computer-generated list of 114 patients selected for the retrospective chart review was used to evaluate clinical outcomes in patients enrolled in the PCMHI clinic 1 year preincorporation and postincorporation of CPS. Outcome measures included the number of patients discharged from the PCMHI clinic upon achieving therapeutic goals or discharged to specialty mental health due to therapeutic failure or adverse drug events with first- and second-line psychotropic agents. Results: When contrasting the end points, there was a 60% increase in the number of patients who achieved therapeutic goal and a 32% decrease in the number of patients discharged to specialty mental health clinic postincorporation of CPS into PCMHI as compared to preincorporation of CPS (P = .024). Discussion: The results support the significance of CPS in the PCMHI in providing pharmacotherapy, patient education, and medication monitoring for managing psychiatric conditions, such as depression, anxiety, and insomnia. In addition, patients had greater accessibility to medication and frequent monitoring and follow-up, ultimately improving patient outcomes.

Abstract:

Abstract It has been suggested that mast cells might serve, under certain circumstances, as antigen-presenting cells (APCs) for T cells. However, whether cognate interactions between mast cells and class II–restricted CD4+ T cells actually occur is still an open question. We addressed this question by using peritoneal cell–derived mast cells (PCMCs) and freshly isolated peritoneal mast cells as APC models. Our results show that in vitro treatment of PCMCs with interferon-γ and interleukin-4 induced surface expression of mature major histocompatibility complex class II molecules and CD86. When interferon-γ/interleukin-4–primed PCMCs were used as APCs for CD4+ T cells, they induced activation of effector T cells but not of their naive counterparts as evidenced by CD69 up-regulation, proliferation, and cytokine production. Confocal laser scanning microscopy showed that CD4+ T cells formed immunological synapses and polarized their secretory machinery toward both antigen-loaded PCMCs and freshly isolated peritoneal mast cells. Finally, on cognate interaction with CD4+ T cells, mast cells lowered their threshold of activation via FcϵRI. Our results show that mast cells can establish cognate interactions with class II–restricted helper T cells, implying that they can actually serve as resident APCs in inflamed tissues.

Abstract:

ABSTRACT Pneumocystis carinii is an opportunistic fungus causing severe pneumonia in immune-compromised hosts. Recent evidence suggests that Pneumocystis exists as separate sex types, though definitive evidence is currently lacking. These studies were undertaken to determine whether Pneumocystis maintains functional meiotic control molecules, which are required for sexual life stages in eukaryotes. Using the Pneumocystis carinii Genome Project database, two partial sequences for meiotic control molecules were detected, namely, PCRan1, a presumptive meiotic control kinase, and PCMei2, a homologue to a primary activator of meiosis in Schizosaccharomyces pombe. Rapid amplification of cDNA ends was employed to obtain the full open reading frames and to further investigate the functions of these proteins. These presumptive meiotic control molecules were most homologous to molecules present in S. pombe (52% identical and 67% homologous for PCRan1 and 75% identical and 88% homologous for PCMei2 by BLAST analysis). Heterologous expression of these Pneumocystis meiotic genes in corresponding temperature-sensitive and knockout strains of S. pombe, respectively, further verified the functions of the PCRan1 and PCMei2 proteins. These proteins were further shown to control downstream components of the meiotic pathway in S. pombe. Lastly, in vitro kinase assays were used to determine that PCRan1p phosphorylates PCMei2p. These experiments represent the first characterization of any proteins in P. carinii involved in meiosis and indicate the presence of a conserved meiotic pathway in Pneumocystis. Elucidation of this pathway will be essential in gaining a greater understanding of this important opportunistic fungal pathogen.

Abstract:

Abstract Introduction: The demand for mental health (MH) services has increased as more veterans seek MH care. At the South Texas Veterans Health Care System, Primary Care Mental Health Integration (PCMHI) was developed to manage patients with uncomplicated MH conditions, including depression, anxiety, or posttraumatic stress disorder (PTSD), within an interdisciplinary primary care (PC) team that includes clinical pharmacy specialists (CPSs). Pharmacists have improved outcomes and access to care for many chronic medical conditions, but limited data demonstrate the impact of MH pharmacists within PC. Methods: This project evaluated the impact of a PCMHI CPS clinic on managing patients with recent antidepressant initiation and CPS clinic intake from September 2015 through December 2016, including follow-up through January 2017. Markers used to evaluate effectiveness of the service included the Patient Health Questionnaire-9 scores, antidepressant medication possession ratio, number of emergency department visits for MH-related concerns, patient engagement in concurrent psychotherapy, and referrals to specialty MH providers. Results: A total of 196 unique patients had intake with the PCMHI CPS in the time specified; 172 of these patients were included in analyses. There were 155 patients maintained in PC. Average Patient Health Questionnaire-9 scores decreased from 14.5 to 8.5, with 63 patients (46%) achieving response and 42 patients (31%) achieving remission. The average antidepressant medication possession ratio was 0.93 for all included patients. Discussion: A PCMHI CPS successfully manages and maintains patients with uncomplicated MH conditions in PC through evidence-based pharmacotherapy, as evidenced by symptom improvement, medication adherence, and low rate of specialty MH referrals.

Abstract:

Abstract In arthropods, the moult-inhibiting hormone (MIH), the ecdysone receptor (EcR), and the retinoid X receptor (RXR) are key regulators in moulting. In the present study, the full-length cDNAs of the MIH, EcR2, and RXR3 genes from the red swamp crayfish, Procambarus clarkii (Girard, 1852) (denoted as PcMIH, PcEcR2, and PcRXR3) were cloned. Tissue-specific and moult stage-specific mRNA expression patterns of these genes were detected by real-time quantitative polymerase chain reaction. PcMIH was detected only in the eyestalk, whereas PcEcR2 and PcRXR3 mRNA were expressed in all tissues tested. The highest levels of PcEcR2 and PcRXR3 were detected in the gill and hepatopancreas. Expression of PcMIH mRNA in the eyestalk increased from postmoult to peak in intermoult and then decreased in premoult. Expression of PcEcR2 mRNA in the eyestalk, hepatopancreas, and muscle increased from postmoult to peak in early premoult and then decreased. However, expression of PcEcR2 mRNA in the gill increased from postmoult to reach a maximum in intermoult and then decreased in premoult. Expression of PcRXR3 mRNA also fluctuated in the eyestalk, hepatopancreas, muscle, and gill, with a decrease from postmoult to late premoult. Expression of PcEcR2 and PcRXR3 mRNA increased relative to the control in the hepatopancreas and gill after unilateral and bilateral eyestalk ablation, which suggested that PcMIH can inhibit their mRNA expression. Double-stranded RNA-mediated RNA interference of PcRXR3 caused different changes in mRNA expression of these genes in different tissues and resulted in decreased expression of PcEcR2 mRNA, which suggested a collaborative relationship between PcEcR2 and PcRXR3.

Abstract:

ObjectivesTo determine professional footballers’ level of understanding of the purpose of the precompetition medical assessment (PCMA) and to evaluate their knowledge of potential outcomes following a PCMA, including disqualification.MethodsProfessional footballers from the Australasian A-League and Westfield W-League were asked to complete a 25-question survey. The relationship between dichotomised outcomes and explanatory variables was analysed with multivariate logistic regression; p<0.05 was considered statistically significant.ResultsA total of 212 players participated (response rate=48.8%). Most respondents selected ‘To detect medical conditions that may affect performance’ and ‘To detect current injuries’ (n=137, 64.6%; n=130, 61.3%) as the purpose of a PCMA. Approximately one-third (n=74, 38.1%) were neutral or believed that a normal PCMA prevented cardiac arrest. Receiving more PCMAs (p<0.0003) and receiving an explanation during their PCMA (p=0.0175) led to greater awareness of the assessment’s limitations. Most participants did not know the definitions of syncope (n=181, 93.3%) or Marfan syndrome (n=183, 94.3%). Fifty players (28.1%) did not know that disqualification was a possible outcome of a PCMA, and younger players were less aware of this possible outcome (p=0.0216).ConclusionProfessional footballers appear to have a limited understanding of the purpose of a PCMA, emphasising the musculoskeletal system and performance. They also appear unfamiliar with the components of the PCMA and medical terms. Finally, many are unaware that disqualification can result from an abnormal PCMA. Player health knowledge must be improved; the informed consent process appears an ideal time to provide this education.

Abstract:

OBJECT Petroclival meningiomas are among the most challenging intracranial tumors to treat surgically. Many skull base approaches have been described to improve resection and decrease patient morbidity. The authors undertook this study to evaluate the results of their treatment of petroclival meningiomas using objective measurements of tumor volume and a new impairment scoring system to assess neurological symptoms that severely affect the patient's quality of life, such as impairment of swallowing and speaking, motor function, and consciousness and communication. METHODS Between January 1990 and December 2009, the authors used a combined transpetrosal approach to treat 60 patients with benign (WHO Grade I) petroclival meningiomas. In this retrospective study, all 60 cases were analyzed in detail with regard to tumor volume, extent of resection (EOR), long-term tumor control, neurological outcome, and the patient condition. In addition, patients were divided into 2 groups according to the period during which the surgery was performed: the early group, from 1990 to 1999, and the late group, from 2000 to 2009. A new scoring system, the petroclival meningioma impairment scale (PCMIS), was created for quantitative assessment of 8 categories of neurological functions, with scores assigned in each category according to the level of disability and its impact on the patient. The PCMIS was used preoperatively, at 3 months after surgery, and at the time of the last follow-up examination, and the results for the 2 groups were compared. RESULTS There were 24 cases in the early group (1990–1999), and the mean duration of follow-up was 149.3 months. The mean EOR was 96.1%, and good long-term tumor control was obtained in 22 patients (91.7%). One of patients died because of a postoperative complication in the perioperative period. The PCMIS improved in 3 patients (12.5%), remained stable in 1 (4.2%), and worsened in 20 (83.3%). There were 36 cases in the late group (2000–2009), and the mean duration of follow-up was 77.9 months. The mean EOR was 92.7%, and good long-term tumor control was obtained in 34 patients (94.4%). The PCMIS score improved in 23 patients (63.9%), remained stable in 5 (13.9%), and worsened in 8 (22.2%). CONCLUSIONS The combined transpetrosal approach has provided satisfactory functional improvements and excellent tumor control for patients with petroclival meningiomas. The PCMIS provides a specific tool for quantitative assessment of the patient's state.

Abstract:

Objective: The objective of the study was to evaluate the cerebrospinal fluid (CSF) flow alterations in meningitis using phase-contrast magnetic resonance imaging (PCMRI). Materials and Methods: Fifty patients with clinically confirmed or strongly suspected infectious meningitis and 20 controls were evaluated with MRI. Quantitative CSF analysis was performed at the level of cerebral aqueduct using cardiac-gated PCMRI. Velocity encoding (Venc) was kept at 20 cm/s. Patients were subdivided into Group I (patients with hydrocephalus [n = 21]) and Group II (patients without hydrocephalus [n = 29]). Results: The mean peak velocity and stroke volume in controls were 2.49 ± 0.86 cm/s and 13.23 ± 6.84 µl and in patients were 2.85 ± 2.90 cm/s and 16.30 ± 20.02 µl, respectively. A wide variation of flow parameters was noted in meningitis irrespective of the degree of ventricular dilatation. A significant difference in peak velocity and stroke volume was noted in Group II as compared to controls. Viral meningitis showed milder alteration of CSF flow dynamics as compared to bacterial and tuberculous etiologies. At a cutoff value of 3.57 cm/s in peak CSF velocity, the specificity was 100% and sensitivity was 22.7% to differentiate between viral and non-viral meningitis. Conclusion: Alteration of CSF flow dynamics on PCMRI can improve segregation of patients into viral and non- viral etiologies, especially in those in whom contrast is contraindicated or not recommended. This may aid in institution of appropriate clinical treatment.

Abstract:

Background Poor patient experiences during delivery in Uttar Pradesh, India is a common problem. It delays presentation at facilities after the onset of labor and contributes to poor maternal health outcomes. Patient-centered maternity care (PCMC) is recognized by the World Health Organization as critical to overall quality. Changing PCMC requires changing the process of care, and is therefore especially challenging. Methods We used a matched case-control design to evaluate a quality improvement process directed at PCMC and based on widely established team-based methods used in many OECD countries. The intervention was introduced into three government facilities and teams supported to brainstorm and test improvements over 12 months. Progress was measured through pre-post interviews with new mothers, scored using a validated PCMC scale. Analysis included chi-squared and difference-in-difference tests. Findings On a scale to 100, the PCMC score of the intervention group increased 22.9 points compared to controls. Deliveries attended by midwives, dais, ASHAs or non-skilled providers resulted in significantly higher PCMC scores than those attended to by nurses or doctors. The intervention was associated with one additional visit from a doctor and over two additional visits from nurses per day, compared to the control group. Interpretation This study has demonstrated the effectiveness of a team-based quality improvement intervention to ameliorate women’s childbirth experiences. These improvements were locally designed and led, and offer a model for potential replication.

Abstract:

Abstract. Tropical convective activity represents a source of predictability for mid-latitude weather in the Northern Hemisphere. In winter, the El Niño–Southern Oscillation (ENSO) is the dominant source of predictability in the tropics and extratropics, but its role in summer is much less pronounced and the exact teleconnection pathways are not well understood. Here, we assess how tropical convection interacts with mid-latitude summer circulation at different intra-seasonal timescales and how ENSO affects these interactions. First, we apply maximum covariance analysis (MCA) between tropical convective activity and mid-latitude geopotential height fields to identify the dominant modes of interaction. The first MCA mode connects the South Asian monsoon with the mid-latitude circumglobal teleconnection pattern. The second MCA mode connects the western North Pacific summer monsoon in the tropics with a wave-5 pattern centred over the North Pacific High in the mid-latitudes. We show that the MCA patterns are fairly insensitive to the selected intra-seasonal timescale from weekly to 4-weekly data. To study the potential causal interdependencies between these modes and with other atmospheric fields, we apply the causal discovery method PCMCI at different timescales. PCMCI extends standard correlation analysis by removing the confounding effects of autocorrelation, indirect links and common drivers. In general, there is a two-way causal interaction between the tropics and mid-latitudes, but the strength and sometimes sign of the causal link are timescale dependent. We introduce causal maps that show the regionally specific causal effect from each MCA mode. Those maps confirm the dominant patterns of interaction and in addition highlight specific mid-latitude regions that are most strongly connected to tropical convection. In general, the identified causal teleconnection patterns are only mildly affected by ENSO and the tropical mid-latitude linkages remain similar. Still, La Niña strengthens the South Asian monsoon generating a stronger response in the mid-latitudes, while during El Niño years the Pacific pattern is reinforced. This study paves the way for process-based validation of boreal summer teleconnections in (sub-)seasonal forecast models and climate models and therefore works towards improved sub-seasonal predictions and climate projections.

Abstract Introduction: Primary care mental health integration (PCMHI) teams function to improve access and quality of integrative physical and mental health (MH) care through a stepped care treatment approach. The project's primary objective was to evaluate the impact a PCMHI clinical pharmacist made on treatment outcomes and interventions. The secondary objective was to assess medication adherence rates. Methods: An electronic medical record was used to identify PCMHI patient referrals for medication management during an 8-month period. Patients were included if they were at least 18 years old and referred for medication management of depression, anxiety, posttraumatic stress disorder, or alcohol use disorder. The scores for the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder Questionnaire (GAD-7), and the Posttraumatic Stress Disorder Checklist (PCL-C) were recorded at baseline and weeks 4, 8, and 12 during treatment. Results: The analysis included 50 patients, which resulted in a total of 156 contacts between July 2014 and March 2015. The mean change in PHQ-9, GAD-7, and PCL-C scores at week 12 as compared to baseline were a decrease of 10 (95% confidence interval [CI], 6.2-13.8, P < .001), 8 (95% CI, 3.1-12.9, P = .006), and 14.5 (95% CI, –17.3-46.3, P = .109), respectively. A total of 336 treatment interventions were made, and the overall medication adherence rate was 82.9%. Discussion: Medication management, provided by a clinical pharmacist, was associated with a statistically and clinically significant improvement on several MH disorder rating scale scores.

Abstract:

Person-centered maternity care (PCMC) is defined as care which is respectful of and responsive to women’s and families’ preferences, needs, and values. In this cross-sectional study we aimed to evaluate the correlations among the degree of PCMC implementation, key indicators of provision of care, and women’s satisfaction with maternity care in Sri Lanka. Degree of PCMC implementation was assessed using a validated questionnaire. Provision of good key practices was measured with the World Health Organization (WHO) Bologna Score, whose items include: 1) companionship in childbirth; 2) use of partogram; 3) absence of labor stimulation; 4) childbirth in non-supine position; 5) skin-to-skin contact. Women’s overall satisfaction was assessed on a 1–10 Likert scale. Among 400 women giving birth vaginally, 207 (51.8%) had at least one clinical risk factor and 52 (13.0%) at least one complication. The PCMC implementation mean score was 42.3 (95%CI 41.3–43.4), out of a maximum score of 90. Overall, while 367 (91.8%) women were monitored with a partogram, and 293 (73.3%) delivered non-supine, only 19 (4.8%) did not receive labour stimulation, only 38 (9.5%) had a companion at childbirth, and 165 (41.3%) had skin-to-skin contact immediately after birth. The median total satisfaction score was 7 (IQR 5–9). PCMC implementation had a moderate correlation with women’s satisfaction (r = 0.58), while Bologna score had a very low correlation both with satisfaction (r = 0.12), and PCMC (r = 0.20). Factors significantly associated with higher PCMC score were number of pregnancies (p = 0.015), ethnicity (p<0.001), presence of a companion at childbirth (p = 0.037); absence of labor stimulation (p = 0.019); delivery in non-supine position (p = 0.016); and skin-to-skin contact (p = 0.005). Study findings indicate evidence of poor-quality care across several domains of mistreatment in childbirth in Sri Lanka. In addition, patient satisfaction as an indicator of quality care is inadequate to inform health systems reform.

Abstract:

Primary cutaneous mucinous carcinoma (PCMC) also known as primary mucinous carcinoma of the skin (PMCS) or primary mucinous eccrine carcinoma (PMEC) is a rare malignant adnexal tumour of eccrine origin. Many visceral mucinous carcinomas especially of the breast and gastrointestinal tract can metastasize to the skin mimicking PCMC. Hence it is very important to rule out metastatic mucinous carcinomas before making a diagnosis of PCMC. Usually, PCMC presents as a slowgrowing tumour of considerably smaller size compared to our case. The large size and shorter duration are the key features of this case report. Here we report an unusually large-sized rare malignant tumour of skin appendage. Our patient was a 54-year-old lady who presented with progressive swelling of one year duration in the right frontoparietal area. Ultrasonography showed an ill-defined lesion in the subcutaneous plane with multiple cystic spaces within it. No bone involvement was noted. The excised lesion measured 13 x 7 x 2 cms and was diagnosed as primary cutaneous mucinous carcinoma on histopathological examination. The possibility of cutaneous secondaries from elsewhere was ruled out by detailed clinical and radiological investigations. The case is reported considering the unusually bigger size and shorter duration of this rare entity.

Abstract:

The quality of waterproof and cohesive layer determines the service life of bridge deck pavement. Conventional modified bitumen bonding layer exits some deficiencies that its shear strength is low, construction process is complexity and it need to spread gravel. In order to solve the problem, the new type of waterproof and cohesive layer called PCMA is developed and researched. Through the indoor test study on road performance of the PCMA, the results shows that PCMAs shear strength, drawing stress and fatigue life are significantly higher than other waterproof and cohesive layer. It is especially suitable for hot and humid regions.

Abstract:

Purpose Adolescents with cancer may access oncologic care from pediatric or adult medical centers, given overlapping age eligibility. However, some recent data suggest a benefit to adolescents with certain cancers when treated at pediatric centers or on pediatric protocols. We used a population-based registry to determine the site of care of children, adolescents, and young adults (age 0 to 24 years) with newly diagnosed cancer. Patients and Methods From the Utah Cancer Registry 1994 to 2000, new malignant cases in patients aged 0 to 24 years were chosen; data including diagnosis, home ZIP code and sites of oncologic care were abstracted. Distance between home ZIP code and Primary Children's Medical Center (PCMC; Salt Lake City, Utah), the state's sole site of pediatric oncology care, was determined. Results Sixty-six percent of Utah 15- to 19-year-olds with cancer were never seen by a PCMC oncologist. Even among this narrow age range, utilization of the pediatric center dropped with each additional year of age. Not unexpectedly, few of those with epithelial malignancies in this age group were seen at PCMC. But surprisingly, 47% of the older adolescents with leukemia, 66% with brain tumors, and 71% with lymphoma never saw a pediatric oncologist. After consideration of age and diagnosis, distance the patient lived from PCMC had a negligible effect on the likelihood of an adolescent being seen there. Conclusion The referral of adolescents with cancer to a pediatric oncology center diminishes greatly with age, and is moderately influenced by diagnosis and minimally by distance from center. Further study should investigate reasons for referral patterns, and impact on outcomes.

Abstract:

AbstractDetecting communities in large-scale social networks is a challenging task where each vertex may belong to multiple communities. Such behavior of vertices and the implied strong overlaps among communities render many detection algorithms invalid. We develop a Partial Community Merger Algorithm (PCMA) for detecting communities with significant overlaps as well as slightly overlapping and disjoint ones. It is a bottom-up approach based on properly reassembling partial information of communities revealed in ego networks of vertices to reconstruct complete communities. We propose a novel similarity measure of communities and an efficient merger process to address the two key issues—noise control and merger order—in implementing this approach. PCMA is tested against two benchmarks and overall it outperforms all compared algorithms in both accuracy and efficiency. It is applied to two huge online social networks, Friendster and Sina Weibo. Millions of communities are detected and they are of higher qualities than the corresponding metadata groups. We find that the latter should not be regarded as the ground-truth of structural communities. The significant overlapping pattern found in the detected communities confirms the need of new algorithms, such as PCMA, to handle multiple memberships of vertices in social networks.

Abstract:

Abstract The association between the quality and nature of social relationships and suicidal outcomes across the lifespan is well established. However, social ties are rarely assessed in primary care and other clinical settings where older adults at high risk for suicide-related outcomes are seen. This study examined the unique associations between three indices of social ties (i.e., perceived social support, frequency of negative social exchanges, and degree of social integration) and death/suicidal ideation among 3,261 older veterans (aged 65+) who completed a clinical mental health/substance use (MH/SU) assessment upon referral to a Primary Care-Mental Health Integration (PCMHI) program. Data on sociodemographics, MH/SU conditions (e.g., depression, anxiety, and substance use), perceived health, the three indices of social ties, and death/suicidal ideation were extracted from clinical interviews. Veterans were on average 70.8 years old (+6.5 years) and primarily male. Approximately half were married and 60.3% were non-Hispanic white. Forty percent reported death ideation or suicidal ideation, as measured by the Paykel Suicide Scale. Logistic regression analyses revealed that, adjusting for covariates, while perceived social support was associated with a greater risk of reporting death ideation relative to no ideation, both social support and frequency of negative exchanges were uniquely associated with greater risk of reporting suicidal ideation relative to no ideation. Social integration was unrelated to odds of death or suicidal ideation. Findings underscore the value of integrating assessments of multiple aspects of social ties into routine PCMHI practice, as doing so has the potential to enhance suicide screening and intervention efforts.

Abstract:

Abstract Objective Aim of this study is to evaluate the effect of craniospinal interventions on cerebrospinal fluid (CSF) flow hydrodynamics and study the correlation of postoperative changes in flow alteration with clinical outcome. Materials and Methods Fifty patients who underwent various craniospinal procedures were studied using conventional and phase-contrast magnetic resonance imaging (PCMRI) protocol. CSF flow quantification was performed at cerebral aqueduct, foramen magnum, C2–3, and D12–L1 vertebral levels with site showing maximal alteration of CSF flow dynamics considered as the region of interest. Velocity encoding was kept at 20 cm/s. Patients with pathology atcraniovertebral junction were considered separately (group I) from others (group II) due to different flow dynamics. Follow-up scans were performed after an interval of 1 month for temporal evaluation of changes in CSF flow dynamics. Results Patients in both groups showed a significant change in peak CSF velocity postoperatively (mean change of 1.34 cm/s in group I and 0.28 cm/s in group II) with bidirectional improvement in flow on cine-phase-contrast qualitative images. Regional pain (82%) and headache (46%) were seen in most of the patients preoperatively. Postoperatively clinical symptoms improved in 59.5%, static in 26.2%, and worsened in 14.3%. In both the groups, an improvement in clinical symptomatology had significant correlation with mean changes in peak CSF velocity postoperatively (p = 0.04 in both groups). Conclusion PCMRI can effectively evaluate changes in CSF flow noninvasively both pre- and postoperatively. This may have potential role in determining clinical outcome and prognosis of patients undergoing procedures in craniospinal axis.

Abstract:

For paired carrier multiple access (PCMA) signals, a new single-channel blind separation on neural network was proposed. Firstly, the sample waveforms (three symbols) which contains different bit information are constructed, secondly, the time-frequency spectrum of each sample under the different influences of the trailing symbols is Intercepted, finally, the characteristic data of the spectrum as the input data, and the two-bit sequence in each sample as the output data to be trained, network trains these data repeatedly to complete the construction of separation model. The receiver carries on window truncation to the time-frequency spectrum of PCMA signal, neural network recognize the characteristic data of these spectrums to realizes the separation of bit sequences. Experimental results show that this algorithm has lower complexity than PSP algorithm, and the accuracy of it is close to PSP algorithm (L=5).

Abstract:

Drug-induced hepatorenal damage is a significant worldwide clinical challenge. In Nigeria, Copaifera salikounda seed pod ethanol extract (CSSPEE) is used in the treatment of many ailments including liver disorders. This study investigated the protective efficacy of CSSPEE against paracetamol (PCM) induced hepatorenal toxicity.Male albino Wistar rats were assigned at random into five different groups (n = 6). The normal control (Group I) was given normal saline via oral administration while Group II was given 500 mg/kg body weight of PCMvia intra-peritoneal administration; Group III was administered 100 mgkg-1 of silymarin (reference drug) while Groups IV and V were administered 200 and 400 mg kg-1 of CSSPEE, respectively, per os for seven days prior to administration of PCM. CSSPEEpretreated groups protected PCM-induced hepatorenal damage as reflected by significant diminution (P < 0.05) in liver enzymes activities and levels of malondialdehyde (MDA), total bilirubin (TB), triglycerides (TG) and urea in comparison with group II. Also, CSSPEE pretreatment significantly increased (P < 0.05) the activities of catalase and GSH relative to group II while no significant elevation (P > 0.05) in superoxide dismutase (SOD), glutathione peroxidase (GPx), and high-density lipoprotein (HDL) was observed in comparison to PCM group. CSSPEE also reversed liver and kidney PCMoverdose caused histopathological alterations and ameliorated the tissue histology thereby corroborating the results of biochemical findings. CSSPEE produced analogous effects comparable to those produced by silymarin (reference drug). The results indicated that oral administration of CSSPEE conferred a dose-dependent protection against paracetamol-induced oxidative damage to liver and kidney.

Abstract:

This paper investigates an improved current predictive model control (PCMC) strategy with a prediction horizon of one sampling time for voltage regulation in standalone system based on diesel engine driven fixed speed of a synchronous generator. An adaptive PR controller with anti-windup scheme is employed to achieve high performance regulation without saturation issues. In addition, new method to obtain the optimal parameters of the adaptive PR controller to achieve high performance during the transition and in steady state is provided. To balance the power at the point of common coupling (PCC) as well as to feed a clean power to the connected loads, a three-phase voltage source inverter (VSI) with LRC filter is controlled using the developed improved PCMC strategy, where the output filter current is controlled using the predicting of the system behaviour model in the future step, at each sampling prediction time. The performances of the proposed configuration and the improved control strategy are verified using Matlab/Simulink interface.
