Background: Plantar ulcers are one of the significant causes of morbidity in diabetic and non- diabetic neuropathic foot and remain a major initiating event for amputation. This randomized controlled trial was carried out to establish the benefits of the 'Mandakini' dressing in comparison with conventional wet gauze dressings, in patients with neuropathic plantar ulcers.Methods: The treatment group received ‘Mandakini’ dressing which was changed every week. Control group received conventional wet gauze dressings. Size of the ulcer, grade of the ulcer and wound surface area was assessed at the end of every week up to 6 weeks in both groups. The percentage of wound covered with granulation tissue, the percentage of wound covered with non-viable tissue and the time taken for healing of the ulcer were compared between the two groups.Results: A total of 60 patients were randomized into treatment and control group with 30 patients in each. The ‘Mandakini’ dressing group had a significant reduction in the wound size at 6 weeks compared to the control group (1.29 vs. 2.31 cm2; p ≤0.0001). Time taken for healing of the ulcer was significantly less in ‘Mandakini’ dressing group (4.83 vs. 5.4 weeks; p=0.013).Conclusions: Mandakini dressing significantly reduces the wound size and time taken for the healing of plantar ulcer compared to conventional wet gauze dressing. Patient acceptability, patient satisfaction, quality of life and cost of the total treatment were better in Mandakini dressing group.

Full textAbstract:
The skin serves as a critical barrier against external pathogens, and its wound healing is a complex biological process that requires careful management to ensure optimal tissue regeneration. Hydrogels, a class of hydrophilic polymers, have emerged as promising materials for wound dressings due to their biocompatibility, biodegradability, and ability to create a moist wound environment conducive to cell proliferation and migration. In this research, a hydrogel dressing containing cefdinir (Cef) was made from a combination of carboxymethyl cellulose (CMC) and gelatin (Gel) by a physical crosslinking method, and their physicochemical, mechanical, and biological properties were investigated. Results show that the addition of Cef does not cause a significant change in the morphology or the tensile strength of the wound dressing. The swelling and degradation rate of the hydrogel slightly increased in the presence of Cef. The presence of Cef enhanced antibacterial effects up to 2.5-fold against P. aeruginosa (35 mm), S. aureus (36 mm), and S. pyogenes (35 mm). The results of the cytotoxicity test showed the absence of cytotoxicity in both drug-containing and drug-free wound dressings, as well as a survival rate of over 75% in cells after 48 h. The drug-containing wound dressing accelerates the formation of the epidermis layer and the production of fibroblast cells, and as a result, accelerates the wound healing process. The percentage of wound healing on the ninth day of treatment for an untreated wound was 30%, while this percentage was 40% with a wound dressing without medicine and 60% with a wound dressing containing medicine, and on the fifteenth day of treatment, the wound treated with both wound dressings had more than 85% healing. As a result, it is possible to use CMC/Gel hydrogel polymeric wound dressing containing Cef as a wound dressing for wound healing, according to the desired physicochemical properties and biocompatibility.

Objective: This study aimed to compare two dressing methods used as skin graft bolsters. The two dressings were compared as to efficacy (% graft take), ease of application, pain scores, safety (complication rate) and cost. Methods: This is a prospective randomized controlled trial involving 34 patients. The basis of comparison between the two dressing methods included: efficacy determined by percentage of graft take on the 7th and 14th day post-Split Thickness Skin Grafting; ease of the application (amount of time to apply dressing); pain (VAS) scores at 1st, 7th and 14th day post-Split Thickness Skin Grafting; complications and costs. Results: The NPWT group has statistically significant differences from the Tie-Over Bolster group. NPWT took less time to apply the dressing (1-10mins vs 6-15mins), had a higher percentage of graft take (99.05% vs 96.52%), had lower pain scores overall, had lower complication rates (infection: 0% vs 2.94%), and cost less (Php 2,917.00 vs Php 3,684.00). Discussion: The Low-Cost NPWT system was developed in this institution due to the exorbitant cost of commercial NPWT pump and dressing systems. Thus, a week-long NPWT therapy using commercial NPWT systems may cost as much as Php 24,000.00, while the low-cost NPWT alternative only costs Php2,917.00. Conclusions: The locally-developed, low-cost NPWT dressing has been proven to be faster to apply, more effective in integrating split thickness skin grafts, has less discomfort and complications, and is actually cheaper than the conventional tie-over bolster dressings Key words: Negative pressure wound therapy, Tie-over bolster dressing, Split thickness skin grafting

Full textAbstract:
Background: Diabetic foot ulcers (DFU) are one of the major complications of diabetes. Despite proper insulin treatment and a strict diabetic diet, 15% of diabetic population develop non-healing ulcers which leads to amputation of the lower limb. Wound dressings represent a part of the management of diabetic foot ulceration. Normal saline (0.9%) wound dressings have been a useful adjunct in the treatment of open wounds. Topical insulin dressing improves wound healing by regulating oxidative and inflammatory responses. PRP dressing has emerged as an adjunctive and newer method for treating DFUs. Hence, the present study was undertaken to compare the effect of topical insulin, platelet-rich plasma (PRP), and normal saline dressing in healing of DFU. Aims and Objectives: The aim of the study was to study the comparison between topical application of insulin versus PRP versus regular normal saline dressing in healing of DFU. Materials and Methods: It is a duration based prospective comparative study including 60 patients divided equally into normal saline dressing group, topical insulin dressing group and PRP dressing group after they fulfilled all the inclusion and exclusion criteria and after obtaining the proper informed and written consent from relatives/patients. Ulcers at days 0, 7 and 14 in terms of size, depth and percentage reduction in area of wound were analyzed. Results: The mean ulcer size at day 14 in normal saline was 4.19±0.95, in Insulin 2.64±0.83 while 2.08±0.47 in PRP group. The mean ulcer depth at day 14 in normal saline was 5.35±1.18, in insulin 4.30±1.38 while 2.35±1.42 (mm) in PRP group, percentage reduction of mean ulcer size in normal saline was 27.02±4.46, in insulin 50.31±7.53 and 63.80±5.75% in PRP group. Conclusion: PRP appears to be a promising agent in terms of faster wound healing, more significant reduction in the size of DFU as compared to topical insulin and other conventional dressings.

Full textAbstract:
In a multicentre, prospective, randomised trial of 44 patients with exuding leg ulcers, a new hydrofibre dressing was compared with an alginate dressing in terms of dressing performance, patient comfort, safety and cost-effectiveness. The groups were well matched with regard to sex and age. A statistically significant difference between treatment groups was observed in mean wear time, with a longer wear time of four days observed in the hydrofibre dressing group compared to three days in the alginate group. The hydrofibre dressing group therefore demonstrated a significantly lower frequency of dressing changes required per week. Significantly more patients achieved a seven-day wear time with the hydrofibre dressing than with the alginate dressing. There was no difference with regard to percentage change in ulcer area. Cost-effectiveness was based on the cost of dressings, compression therapy and nursing time to achieve a healed wound. However, because of small patient numbers, it was difficult to make an accurate comparison. This study suggests that the hydrofibre dressing may have clinical benefits that merit further investigation with larger patient numbers.

Full textAbstract:
Objective: To compare the effectiveness of two commonly used moist dressings, Aquacel and Aquacel Foam (both ConvaTec Ltd., UK), in managing split-thickness skin graft (STSG) donor site wounds. Method: Patients undergoing STSG harvesting for reconstruction were eligible for this quasi-experimental study. After reconstruction surgery, the Aquacel (A) or Aquacel Foam (AF) dressings were applied on the donor site wound. The STSG donor site was assessed by two trained research nurses daily. Clinical outcomes including pain on dressing removal, use of intravenous analgesics, signs and symptoms of wound infection, incidence of exudate leakage and percentage healed were recorded in a standardised form. Cost of the dressing change was retrieved from the hospital billing system. Results: Of 50 patients recruited, 25 received dressing A and 25 received the AF dressing for their STSG donor site wound. The average pain score on dressing removal was significantly lower in the AF dressing group compared with the A dressing group (0.8±0.8 versus 3.1±1.5, respectively (p=0.04)). Regression analysis demonstrated that compared with dressing A, the AF dressing was associated with a lower average pain score (beta: –2.27, standard error: 0.33; p<0.001), lower likelihood of pro re nata (PRN) intravenous analgesic use (odds ratio (OR)=0.21, 95% confidence interval: 0.06–0.71; p=0.01) and lower likelihood of exudate leakage (OR=0.11, p=0.01). The differences in time to wound healing, infection and cost were not statistically significant between the two groups. Conclusion: In this study, the AF dressing demonstrated superior performance in pain response on dressing removal for STSG donor site wounds compared with dressing A. Large-scale randomised controlled trials should be conducted to confirm the findings.

The aim of the study was to determine the effect of feed additives (algae, soybean, and sunflower oil) used in the rabbit feed on: growth indices and slaughter traits, pH, colour, texture, chemical composition, fatty acid profile and oxidative stability (TBARS) of the meat as well as FTO and FABP4 genes expression in the meat’s intramuscular fat (m. longissimus lumborum), depending on the age and sex. The experimental material consisted of Termond White rabbits (n = 160, 80 females and 80 males). Animals were weaned on the 35th day of life, and housed in metal cages arranged in batteries (4 rabbits of the same sex in a cage). From weaning to 12 or 18 weeks of age, the rabbits were fed pellets ad libitum. Animals in the control group (C) received non-supplemented pellets throughout the experiment. In the other groups, the pellet contained 1% algae (A), 3% sunflower oil (OS), and 3% soybean oil(SO).The experimental diets were formulated to have similar protein and energy content. Diets were balanced by lowering the proportion of other feed components. The total share of all components remained at 100%. The results indicate that 3% vegetable oils (soybean or sunflower) supplementation of diets for growing rabbits leads to an increase of body weight and improvement of some of the slaughter traits, while 1% addition of algae to the feed causes deterioration of body weight and slaughter traits. The effect of oil additive depends on the animals’ age. Supplementation of the rabbits’ diet with algae (1%) or sunflower and soybean oils (3%) led to an increase in the dressing percentage of rabbits slaughtered at 18 weeks of age (approx. 3%), but had no effect on the dressing percentage of rabbits slaughtered at 12 weeks of age. Feeding pellets with either 3% vegetable oils or 1% algae additive to the rabbits did not significantly change the chemical composition of the meat. Protein content increased and intramuscular fat content decreased with age, while ash and water content were similar. The feed additives significantly differentiated meat acidity without deteriorating meat quality. Diet modification has not affected negatively meat colour. 24 h after the slaughter, the colour of rabbit meat was similar across the studied feeding groups. Correlation between diet and rabbits’ age was found. Meat texture (hardness, springiness and chewiness) of all rabbit groups slaughtered at 12 weeks of age was similar, and the shear for cewas greater in rabbits fed pellets with algae and soybean oil. At 18 weeks of age, rabbit meat from experimental groups had lower hardness and chewiness, compared to meat of the animals from the control group. Meat shear force was higher in the control group, and from algae-supplemented group. The correlation between diet and age was also found. The use of 3% vegetable oils or 1% algae as feed additives significantly reduced meat oxidative stability. Soybean or sunflower oil (3%) usedas feed additives favourably modified the fatty acid composition of intramuscular fat. Polyunsaturated fatty acids (PUFA) content was increased, including linoleic acid, and PUFA/MUFA ratio was improved. The content of these acids decreased with age. The use of algae (1%) as a feed additive resulted in positive effect on the increase of n-3 fatty acid content (EPA and DHA) in meat intramuscular fat. Algae supplementation improved pro-health properties of meat, with low n-6/n-3 acid ratio (2.5), indicating that diet modification may affect the fatty acid composition of rabbit meat. The influence of diet and age on FTO and FABP4 gene expression in meat intramuscular fat (m. longissimus lumborum) was found. FTO and FABP4 gene expression increased with age and was the highest in the group of rabbits with 1% algae supplementation in the diet. The effect of rabbits’ gender on growth, slaughter traits, meat quality and gene expression in rabbits was not observed. In conclusion, the use of natural feed additives, such as sunflower, soybean oil or algae, can improve the nutritional value of rabbit meat, without changing its chemical or physical properties, and therefore the meat can serve as functional food, with properties beneficial to human health. The results obtained in this study also indicate that the expression of FTO and FABP4 genes in rabbit muscles is regulated by dietary factors and age, which, in addition to cognitive significance, has practical implications for improving technological and dietary quality of rabbit meat.

Full textAbstract:
Abstract Superfinishing is an abrasive finishing process in which a smooth work surface is produced by simultaneously loading a bonded abrasive stone against a rotating workpiece surface and oscillating (reciprocating) the stone at high frequencies. The surface topography of a 600 grit aluminum oxide stone used for superfinishing is quantitatively described using scanning phase-shift interferometry. A bounded three-parameter lognormal distribution is found to provide a more accurate representation of cutting edge height distribution than a bounded normal distribution, especially in fitting the upper tail end of data. Moreover, the stone surface characteristics are nearly constant throughout stone life suggesting that superfinishing is a self-dressing process. This stone surface geometry is used to develop a contact mechanics model of the superfinishing process. The model estimates the number of cutting edges involved in material removal, the load distribution on these edges, and the resulting surface roughness of the super-finished surface. The effect of contact pressure on these estimated values has been studied. Only a very small percentage (less than 0.16%) of the cutting edges, which are comprised of the large cutting edges occurring in the tail end of distribution, are actively engaged in material removal. Further, the arithmetic average surface roughness, Ra, is found to be related to the average depth of penetration while the peak-to-valley surface roughness, Rt or Rtm, is related to the maximum depth of penetration. The prediction of surface roughness of this model is found to agree very well with experimental results for superfinishing of hardened steel surfaces.

Abstract Drilling performance is greatly driven by the rate of penetration (ROP) and its optimization. Therefore, accurate prediction of ROP before drilling can help take measures to achieve drilling objectives smoothly. Numerous inter-twined formation and drilling parameters affect the ROP. Consequently, optimizing and predicting ROP is a complex challenge faced by the industry. This study proposes a novel computational intelligence-based (CI) model to predict ROP as a function of multiple readily available mud- and petrophysical- logs. Furthermore, multiple algorithms are utilized, and a comparative analysis is presented. Adaptive Neuro Fuzzy Inference System (ANFIS), along with Artificial Neural Network (ANN) based algorithms are utilized to analyze the data and develop models. A process-based approach is followed starting with systematic data analysis, which includes a selection of the most relevant input parameters, data cleaning, filtering, and data-dressing to ensure optimized inputs into the computational models. This step allows for developing ROP predictor as a function of pivotal formation-related logs such as neutron, density, wave velocity, and gamma ray. Moreover, historical drilling-related parameters such as weight on bit, mud pump parameters, and bit flow rate are also used as model inputs. Next, CI model parameters are tuned for both ANN and ANFIS through a sensitivity analysis on the number of neurons and the cluster radius, respectively. Finally, a comparison of ANN and ANFIS models is performed using graphical and statistical analysis. The developed models are tested on an unseen dataset to verify their efficiency. An error metrics analysis, comprising of average percentage error, root mean squared error, and the correlation coefficientis performed. This analysis ranks the respective CI models based on the highest performance efficiency and lowest prediction error. Resultantly, it is observed that the ANN-based model can perform better than the ANFIS model by accurately predicting ROP. The superior performance of ANN is due to its ability to map the complex non-linear interactions of formation and drilling parameters to the resultant ROP.
