Several factors exert considerable influence on oocyte production and quality, such as donor age, nutrition, season and others. However, very few studies have been done to verify the effects of breed on the quantity or quality of oocytes, or both. In Brazil, the Nellore breed has been developed as a result of many years of selective breeding from 6 major ancestor bulls imported from India in the 1960s. These animals have characterised their respective lineages, as evidenced by the well-defined genetic traits. This study was carried out to investigate the influence of the genetic lineage of oocyte donors on the number and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore cows derived from 2 lineages of bulls [Karvadi (K) and Taj Mahal (T)]. Both maternal (Km and Tm) and paternal (Kp and Tp) lineages were investigated. Oocyte aspirations were repeatedly performed with an aspiration interval of 15 days without the superovulation procedure in 56 donor females over a period of 2 years. At the beginning of the experiment, the animals were on average 78 ± 12 months old with a body condition score of 3.6 ± 0.08 (on a 5-point scale). Recovered cumulus–oocyte complexes were counted, morphologically examined and classified into 7 categories (grades I to VII) according to the number of layers of the cumulus–oocyte and the appearance of the cytoplasm. Data were analysed using ANOVA and Tukey's test after transformation into log(x + 1). Values are reported as means ± s.e.m. and differences (P > 0.05) were taken as significant. The mean number of oocytes retrieved from donors of lineage Tp-Tm was higher (n = 9; 28.23 ± 1.92; P < 0.05) than that obtained for lineages Kp-Tm (n = 11; 21.34 ± 1.32), Kp-Km (n = 15; 21.28 ± 1.73) and Tp-Km (n = 21; 16.72 ± 1.31). There was no significant difference in the mean number of recovered oocytes between donors of lineages Kp-Tm and Kp-Km; however, lineage Tp-Km yielded a lower number of oocytes. Donors of lineage Kp yielded more (P < 0.05) oocytes of grade III than lineage Tp (10.11 ± 0.66 vs 8.79 ± 0.58, respectively). These lineages produced a higher mean number of oocytes graded as I, II and III (3.14 ± 0.21, 4.93 ± 0.33 and 10.11 ± 0.66 vs 3.19 ± 0.21, 5.59 ± 0.44 and 8.79 ± 0.58, respectively) than any other categories. However, more oocytes (P < 0.05) of grades I, II and III were obtained for lineage Tm (3.64 ± 0.25, 5.9 ± 0.42 and 11.67 ± 0.67) than for lineage Km (2.85 ± 0.19, 4.92 ± 0.40 and 7.73 ± 0.56, respectively), with similar results for oocytes of grades IV, V, VI and VII. In conclusion, the genetic lineage of the oocyte donor influenced the production and quality of oocytes obtained through ultrasound-guided follicular aspiration in Nellore cows. Selection of donor cows based on their oocyte morphology and availability can further improve IFV programs.

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.

USG guided coeliac plexus neurolysis become benevolence in these patients on part of their pain management and quality of life improvement. To compare the efficacy of USG guided coeliac plexus neurolysis for pain relief in upper abdominal malignancies by using different concentration of alcohol (50% vs 75%).This Prospective, comparative, randomised double blinded study was conducted during Sep 2019 – Aug 2020 at our tertiary care centre. Total 60 cases were taken as per following inclusion and exclusion criteria and randomly divided into 2 groups i.e. 30 each group, we compare Visual Analogue Scale (VAS) score, quality of life (QOL) and need of rescue analgesia profile between the groups to know the efficacy of USG guided coeliac plexus block. In our study, we observed that the baseline mean VAS score in group I was 8.26±0.78 while in group II was 8.03±0.76. No significant difference was found in mean VAS score at this time between the groups (p=0.24). The baseline mean QOL score in group-I was 77.46±3.40 while for the cases of group II the mean QOL score was 77.36±3.33. No significant difference was found in mean QOL score at baseline between the groups (p=0.90). The baseline mean morphine consumption in group-I was 113.33±39.24 mg while for the cases of group-II the mean morphine consumption was 120.33±38.37mg. No significant difference was found in mean morphine consumption at this time between the groups (p=0.48).Both groups having 50% alcohol and 75% alcohol decreases the VAS score from baseline in patients having upper abdominal malignancies along with QOL and dosages of rescue analgesia whereas no significant difference in VAS score in patients of both groups.

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.

The state of Michigan has been constructing directional crossovers in the medians of boulevard roadways since the 1960s to alleviate the congestion and interlocking that were occurring at bidirectional crossover locations. The objective of this research is to investigate the safety benefits of divided roadway and directional crossover median designs. An investigation of the mean accident rates of roadways with boulevards compared to the mean accident rates of roadways with continuous center left-turn lanes revealed that there is a significant difference, with boulevard roadways having a lower mean accident rate for those Michigan roadways investigated. Investigation into the difference of the mean accident rates for boulevard roadways with medians of different widths indicated that roadways with medians greater than 9.15 m (30 ft) but less than 18.30 m (60 ft) had the lowest mean accident rate of the three median categories investigated. The difference was significant for most accident types when compared to roadways with medians less than or equal to 9.15 m (30 ft) and greater or equal to 18.30 m (60 ft). The investigation of the accident rates for boulevard roadways with directional and bidirectional signalized crossovers, while not conclusive, indicated that boulevard roadways with direction crossovers had a lower mean accident rate than boulevard roadways with bidirectional crossovers for signalized roadways.

The objective of this study was to investigate to what extent fertility and lambing season of fat-tailed ewes raised under an extensive production system are related to liveweight, body condition and changes around mating. Ewe liveweight and body condition score (BSC) were recorded in June, July and August over a period of 3 years (1999–2001) in 11 flocks (eight flocks of Kurdi breed and three flocks of Kurdi × Sanjabi crossbred). Both Kurdi and Sanjabi are native fat-tailed breeds in western Iran. In total, 3278 lambing records relating to 1592 ewes and data on mating date, liveweight and BCS of 1930 ewes (3975 records) were used for statistical analyses. The statistical model for bodyweight and body condition data included fixed effects of breed group, flock nested within breed group, year, the future lambing status following summer breeding (barren, autumn lambing and winter lambing), ewe age and all two-way interactions. Breed group had a significant effect on ewe liveweight (P < 0.01). However, there was no significant difference between BCS of the two breed groups around mating. Ewe liveweights measured in June, July and August had significant effects on fertility and lambing season (P < 0.01). Ewes that produced lambs were generally heavier at mating than barren ewes (P < 0.01). Autumn-lambing ewes were heavier than winter-lambing ewes in June and July (P < 0.01). Effects of changes in liveweight on fertility and lambing season were significant (P < 0.01). The effects of BCS in June, July and August (P < 0.01) and changes in BCS during the mating period (P < 0.05) on fertility and lambing season were also significant. The mean BCS (in June and July) of autumn-lambing ewes was greater than that of the winter-lambing and barren ewes (P < 0.05). The proportion of autumn-lambing ewes significantly increased as BCS in July increased, whereas the proportion of barren ewes decreased (P < 0.01). Fertility was associated with age so that as the age of the ewes increased from 2 to 7 years, the proportion of barren ewes significantly decreased from 29 to 5% (P < 0.01). There was a relatively high proportion of very thin ewes of 2 and 3 years of age. These findings imply that low body condition is a particular problem in younger ewes suggesting the importance of giving special nutritional treatment to younger ewes to reduce the proportion of barren ewes.

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.
