One of the key points in the frozen food processing is thawing with minimal damage to the quality. Since the commonly used methods for thawing of foods are slow and reduce the quality of the product, application of an efficient method seems necessary. In this research, thawing of tuna fish was performed by immersion ohmic method. Thawing rate roles a vital key in the quality and significantly increased by ohmic ([Formula: see text], the mean of ohmic group) in comparison with conventional thawing ([Formula: see text], the mean of conventional group) methods. Immersion ohmic thawing increased rate of thawing about 5 times. Parameters important in quality such as T-VBN, protein solubility, thawing evaporation loss, pH, thawing loss and press juice were measured. Group analyses showed significant difference between ohmic and conventional treatment in protein solubility, thawing evaporation and thawing loss (p < 0.05).

Abstract Background The consequences of obstetric fistula on affected women are more than the medical condition. It has extensive physical, psychological, social, and economic consequences on them. Obstetric fistula affects the entire health and entire life of women. Women suffering from obstetric fistula are often abandoned by her partner, relatives, and the community. This study aimed to determine the quality of life of obstetrics fistula patients before and after surgical repair. Methods Institutional-based prospective, before and after study design was conducted in the Jimma University Medical Center from November 1, 2019–October 30, 2020. A face-to-face interview was conducted with fistula patients who visited Jimma University Medical center, fistula clinic during the study period. All fistula patients were included in the study. Accordingly, 78 women who underwent surgical repair were interviewed. The means and the standard deviation were computed using conventional statistics formulas. The unpaired t-test was used to compare two independent means, and one-way analysis of variance (ANOVA) was used to compare the quality of life before repair and after a successful repair. Linear regression analysis was done for identifying determinants of quality of life. A P value of 0.05 will be considered statistical significance. Result The overall quality of life of women was 58.17 ± 7.2 before the surgical repair and 71.20 ± 10.79 after surgical repair. The result indicates there is a significant difference in the mean value of pre and post-operative (P < 0.001). The overall satisfaction of women with their health status before the surgical repair was 22.5 ± 1.30and it has increased to 53.0 ± .90after surgical repair. The physical health dimension score was 16.51 ± 5.27 before the surgical repair while it has increased to 21.77 ± 5.38 after the surgical repair. The score of the social domain before the surgical repair was 5.19 ± 1.34 and it has increased to 7.13 ± 3.67 after the surgical repair. The score of the environmental health domain was 17.41 ± 2.89 before the surgery while it also increased to 21.65 ± 4.04 after the surgical repair. The results have shown there was a significant difference in the mean values of pre and post-operatives in both social and environmental scores (P < 0.001). The score of the psychological health domain before the surgery was 19.06 ± 1.46 and it was increased to 19.84 ± 3.21 after the surgical repair. The result showed there is a significant difference in mean value pre and post-operative (P = 0.048), though it is a slight improvement compared to other domains. Conclusion The overall quality of life of the patient with fistula was improved after successful surgical repair. Although all domains of quality of life had shown significant improvement after successful surgical repair, the psychological domain showed slight improvement.

Abstract Background and Aims Dialysis patients are often prescribed a large number of medications to improve metabolic control and manage co-existing comorbidities. However, several studies suggest that a large number of medications can also detrimentally affect their health-related quality of life (HRQoL). Therefore, this study aims to provide insight in the association between the number of medications and various aspects of HRQoL in dialysis patients. Method A multicentre study was conducted among dialysis patients from Dutch dialysis centres three months after initiation of dialysis as part of the ongoing prospective DOMESTICO study. The number of medications, defined as the number of concomitantly prescribed types of drugs, was obtained from electronic patient records. Primary outcome was HRQoL measured with the Physical Component Summary (PCS) score and Mental Component Summary (MCS) score (range 0-100) of the Short Form 12. Secondary outcomes were number of symptoms (range 0-30) measured with the Dialysis Symptoms Index and self-rated health (range 0-100) measured with the visual analogue scale of the EuroQol-5D-5L. Data were analysed using linear regression and adjusted for possible confounders, including age, sex, dialysis modality, and comorbidity. Analyses for MCS and number of symptoms were performed after categorising patients in tertiles according to their number of medications because assumptions of linearity were violated for these outcomes. Results A total of 162 patients were included. Mean age of patients was 58 ± 17 years, 35% were female, and 80% underwent haemodialysis. The mean number of medications was 12.2 ± 4.5. Mean PCS and MCS were 36.6 ± 10.2 and 46.8 ± 10.0, respectively. The mean number of symptoms was 12.3 ± 6.9 and mean self-rated health 60.1 ± 20.6. In adjusted analyses, PCS was 0.6 point lower for each additional medication (95%CI -0.9 – -0.2; p=0.002). MCS was 4.9 point lower (95%CI -8.8 – -1.0; p=0.01) and 1.0 point lower (95%CI -5.1 – 3.1; p=0.63) for the highest and middle tertiles of medications, respectively, compared to the lowest tertile. Patients in the highest tertile of medications reported 4.1 more symptoms compared to the lowest tertile (95%CI 1.5 – 6.6; p=0.002) but no significant difference in the number of symptoms was observed between the middle and lowest tertile. Self-rated health was 1.5 point lower for each medication (95%CI -2.2 – -0.7; p&lt;0.001). Conclusion After adjustment for comorbidity and other confounders, a higher number of medications was associated with a lower PCS, MCS, and self-rated health in dialysis patients and with more symptoms. This suggests that it may be relevant to weigh expected therapeutic benefits of medication against their possible harmful effects on HRQoL. An unfavourable balance between expected benefits and impact on HRQoL might be ground to deviate from clinical guidelines, especially for patients with a limited life-expectancy and for whom a kidney transplant is unattainable.

Objectives This research aimed to evaluate the performance of a closed blood collection system and to compare it with an open system in terms of feasibility, tolerability by the donor, quality of blood collected and bacterial contamination. Methods Eight feline blood donors were prospectively and randomly subjected to both collection methods. Heart rate (HR), respiratory rate (RR) and blood pressure (BP) were evaluated before sedation, after sedation and after blood collection. The duration of the donation, the formation of a hematoma, and the degree of hemolysis and packed cell volume (PCV) of each blood unit were evaluated. Aliquot samples were aseptically collected from each unit and tested for bacterial contamination by culture and PCR on days 0, 14 and 28 of storage. Results There was no significant difference between collection methods for HR and RR at any time point. Before sedation, the mean systolic BP was significantly higher with the closed system (closed 169 mmHg, open 137 mmHg; P = 0.003). The average duration of collection was significantly shorter with the closed system (closed 3 mins 10 s, open 8 mins; P = 0.035); however, the prevalence of a successful blood collection with a single venipuncture and hematoma formation were not significantly different between systems. The mean unit PCV was significantly higher with the open system (closed 31%, open 34%; P = 0.026). On bacterial culture, 15/16 units were negative at all time points (closed 7; open 8). Using PCR, 5/16 units were positive for Ralstonia species for at least one time point (closed 3; open 2). Conclusions and relevance Our designed closed system appears to be well adapted to feline blood collection and was well tolerated by the donors, performing similarly to an open system, and could represent a valuable clinical device for the development of a feline blood bank, namely feline blood storage.

The objective of the present study was to evaluate the effect of hyaluronan (HA) during IVM on meiotic maturation, embryonic development, and the quality of oocytes, granulosa cells (GC), and obtained blastocysts. COCs were maturedin vitroin control medium and medium with additional 0.035% or 0.07% of exogenous HA. The meiotic maturity did not differ between the analysed groups. The best rate and the highest quality of obtained blastocysts were observed when 0.07% HA was used. A highly significant difference (P<0.001) was noted in the mean number of apoptotic nuclei per blastocyst and in the DCI between the 0.07% HA and the control blastocysts (P<0.01). Our results suggest that addition of 0.035% HA and 0.07% HA to oocyte maturation media does not affect oocyte nuclear maturation and DNA fragmentation. However, the addition of 0.07% HA during IVM decreases the level of blastocysts DNA fragmentation. Finally, our results suggest that it may be risky to increase the HA concentration during IVM above 0.07% as we found significantly higherBaxmRNA expression levels in GC cultured with 0.07% HA. The final concentration of HA being supplemented to oocyte maturation media is critical for the success of the IVP procedure.

ObjectiveTo assess the quality of eyeglass prescriptions provided by an affordable wavefront autorefractor operated by a minimally trained technician in a low-resource setting.Methods and Analysis708 participants were recruited from consecutive patients registered for routine eye examinations at Aravind Eye Hospital in Madurai, India, or an affiliated rural satellite vision centre. Visual acuity (VA) and patient preference were compared between trial lenses set to two eyeglass prescriptions from (1) a novel wavefront autorefractor and (2) subjective refraction by an experienced refractionist.ResultsThe mean±SD VA was 0.30±0.37, –0.02±0.14 and −0.04±0.11 logarithm of the minimum angle of resolution units before correction, with autorefractor correction and with subjective refraction correction, respectively (all differences p<0.01). Overall, 25% of participants had no preference, 33% preferred eyeglass prescriptions from autorefraction, and 42% preferred eyeglass prescriptions from subjective refraction (p<0.01). Of the 438 patients 40 years old and younger, 96 had no preference and the remainder had no statistically significant difference in preference for subjective refraction prescriptions (51%) versus autorefractor prescriptions (49%) (p=0.52).ConclusionAverage VAs from autorefractor-prescribed eyeglasses were one letter worse than those from subjective refraction. More than half of all participants either had no preference or preferred eyeglasses prescribed by the autorefractor. This marginal difference in quality may warrant autorefractor-based prescriptions, given the portable form factor, short measurement time, low cost and minimal training required to use the autorefractor evaluated here.

In the present study, the application of immersion ohmic heating was examined to improve thawing of frozen tuna fish cubes. The experimental tuna cubes (3 × 3 × 3 cm3) were thawed under ohmic heating subjected to three different voltages (40, 50, and 60 V) with three different concentrations (0.3, 0.4, and 0.5% w/v) of brine solution. The parameters associated with the quality of tuna, such as thawing time, thawing rate, thawing loss, cooking and total losses, centrifugal loss, lipid oxidation, texture, and color, were investigated during ohmic heating thawing, and compared with the conventional still air thawing, water thawing at 27 and 40 ℃. The results showed that immersion ohmic thawing significantly decreased the thawing time of frozen tuna fish cubes. Thawing time in ohmic treatment (50 V- 0.3% brine) was 5.95 times shorter than conventional conditions. The lowest thawing and cooking losses were observed at ohmic treatments. In addition, the ohmic treatments (group 1) were evaluated versus conventional methods (group 2) and the results showed that thawing and total losses in group 1 were significantly lower than group 2.

Objective To evaluate the effect of intra-articular injection of autologous micronized adipose tissue (MAT) with ankle arthroscopic debridement in patients with advanced-stage posttraumatic osteoarthritis (PTOA) of ankle. Design A retrospective cohort study investigating patients treated with arthroscopic debridement and autologous MAT injection for ankle PTOA was performed. Patients with Kellgren-Lawrence (KL) grade 3 to 4 were included. Visual analogue scale (VAS), Foot and Ankle Outcome Scores (FAOS), and patient satisfaction were evaluated. Results A total of 19 patients (19 ankles) were included (KL grade 3, 8 patients; grade 4, 11 patients). At a mean follow-up time of 14.3 months (range, 7-23 months), the mean FAOS subscales for pain and quality of life significantly increased from 48.8 and 20.1 preoperatively to 61.1 and 30.1 ( P = 0.029 and 0.048, respectively). The mean VAS score significantly improved from 6.1 to 3.8 (P = 0.003) at final follow-up. A total of 10.5% (2/19) of patients were very satisfied, 31.6% (6/19) satisfied, 26.3% (5/19) neutral, 21.1% (4/19) unsatisfied, and 10.5% (2/19) very unsatisfied with their outcomes. The overall FAOS score demonstrated a significant difference in pre- to postoperative change with 14.8 for KL grade 3 and 5.9 for KL grade 4 ( P = 0.048). Conclusions Autologous MAT injection is a safe and potentially beneficial procedure for advanced-stage ankle PTOA as an adjunct to arthroscopic debridement, although more than one-third of patients were unsatisfied with the procedure. This procedure may be more beneficial for KL grade 3 patients than grade 4 patients. However, future investigations are necessary to define the role of MAT for ankle PTOA.
