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.

Blood donation is an essential step in transfusion medicine that must take into account the donor’s welfare, collection effectiveness, and blood product quality. This prospective study enrolled 13 canine blood donors, each subjected to both gravity and suction collection methods, in a randomized order. Clinical parameters, including heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), and rectal temperature (RT), were evaluated at four time points, including when the donor was on the floor and on the collection table, and before and after blood donation. The number of times the donor and needle required repositioning, the duration of the donation, the noise created by the apparatus, and the presence of a hematoma were evaluated. The weight, index of hemolysis, and hematocrit of each unit of blood were recorded. There was no significant difference between collection methods for either the clinical parameters at each time point or the prevalence of hematoma formation, the frequency of needle repositioning, the hemolysis index, or hematocrit. Collection by suction was noisier (P < 0.0001), faster (P = 0.004), and associated with significantly less donor repositioning (P = 0.007). Suction appears to be a safe and cost-effective method that should be considered to optimize blood donation.

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.

Background: Meat safety is important for public health. As part of the meat chain abattoirs are required to give attention to meat hygiene and safety in order to minimize hazards. Therefore, the current study was conducted to evaluate the bacteriological quality of sheep carcasses, knowledge and hygienic practices of workers in a selected abattoir and to determine the effect level of 2.5% citric acid spray on total coliforms and aerobic bacteria load of raw sheep carcasses surfaces. Methods: A cross-sectional study design with structured questionnaire and observational checklists observation were used. A systematic random sampling technique was employed. A total of 50 sample swabs (25 swabs before citric acid spray and 25 after citric acid spray) were randomly taken from brisket, flank and rump of sheep’s carcasses. Swabs were moistened with buffered peptone water (BPW) and samples were taken by rubbing 100 cm2 (10 cm × 10 cm) area delineated by sterile aluminum template. In addition, we administered a structured questionnaire and an observational checklists to assess knowledge and hygienic practices of workers. Bacteriological quality of sheep carcasses were analyzed using the methods described by the US bacteriological analytical manual. Results: The mean count for aerobic bacteria of the sheep carcasses before and after citric acid spray were 7.2log10 CFU/ml and 6.4log10 CFU/ml, respectively. The test results also showed that 21 (84%) and 15 (60%) of the swab samples were positive before and after spraying citric acid, respectively. The mean counts for coliform bacterial of the sheep carcasses before and after citric acid spray were 3.5log10 CFU/ml and 2.9log10 CFU/ml, respectively. The mean total aerobic and coliform counts before and after citric acid spray were significantly different ( P < .05). Regarding the hygiene condition of workers, all the respondents reported that they always washed their hands with soap before and after entering the slaughtering room and 23 (53.5%) of the workers reported that they used hot water. Thirty-one (72.1%) of the workers reported that they do not used soap to wash hands after visiting toilet. Thirty-five (81.4%) of the production workers did not wear mouth mask while handling and distribute meat/carcass. On the other hand, all of the workers wore capes, gowns and boots at the time of the observation and only 18 (18.6%) of the production workers wore gloves at the time of the survey. Conclusion: The current study revealed that significant proportion of sheep carcasses were positive for total aerobic bacteria and total coliform. Moreover, the study also showed that spraying of sheep carcasses with 2.5% citric acid significantly reduced the total coliform and aerobic counts. However, we did not assessed how much spray results to this effect. Therefore, we recommended further studies to determine how much spray of 2.5% citric acid significantly reduce bacterial contamination of sheep carcasses. In addition, the abattoir has to follow the food hazard analysis critical control point (HACCP) system to minimize meat contamination during harvesting and processing. The abattoir has to also implement strict operation laws to improve hygiene conditions of the workers. In addition, the abattoir can minimize meat contamination using 2.5% citric acid as a decontaminant.

Objectives The aim of this study was to compare the quality of sedation and recovery, and ease of venipuncture following sedation for feline blood donation using two intramuscular (IM) sedation protocols: alfaxalone/butorphanol (AB) and dexmedetomidine/butorphanol (DB). Methods This was an experimental randomized, blinded, crossover study. Ten client-owned healthy cats were recruited to participate in the study. Cats were sedated with AB (alfaxalone 2 mg/kg and butorphanol 0.2 mg/kg) for one donation and DB (dexmedetomidine 10 μg/kg and butorphanol 0.2 mg/kg) for another. Reaction to injection, quality of sedation and quality of recovery were assessed by a blinded observer. Time to lateral recumbency, number of venipuncture attempts, time required for blood collection and time to return to sternal recumbency were recorded. Cats were monitored for evidence of gastrointestinal distress. Each donation consisted of a maximum of 53 ml whole blood drawn over 3–22 mins. Donors received 100 ml subcutaneous lactated Ringer’s solution in recovery. Owners, unaware of sedation protocol, were asked to complete a questionnaire evaluating their cat’s behavior following sedation. Results IM injections were well tolerated by both treatment groups. There was no significant difference between treatment groups in sedation scores for posture ( P = 0.30) or behavior ( P = 0.06). Cats sedated with DB had significantly higher muscle relaxation scores ( P = 0.03) compared with AB. There was no significant difference between treatment groups in time to lateral recumbency ( P = 0.12), number of venipuncture attempts ( P = 0.91) and time for blood draw ( P = 0.29). There was no difference in quality of recoveries between treatment groups based on simple descriptive scores ( P = 0.18) and owner evaluation 24 h following sedation. One cat vomited following administration of DB. Conclusions and relevance Alfaxalone is a suitable alternative to dexmedetomidine when combined with butorphanol and used as part of an IM sedation protocol for cats undergoing blood donation.

This article describes the semen characteristics from different collection methods between captive and confiscated Malayan pangolins, Manis javanica. Semen was collected from 15 pangolins; two captive and 13 confiscated individuals at the mean weight of 9.36 ± 1.94 kg. The three semen collection methods employed were electroejaculation, rectal massage and a combination of both techniques. The semen characteristics (mean ± standard deviation) of the Malayan pangolin are volume (73.75 ± 144.57 µL), pH (7.63 ± 0.53), spermatozoa concentration (997.19 ± 728.98 × 106 /mL), total motility (59.60% ± 30.00%), progressive motility (48.95% ± 30.93%), mass motility (3.50 ± 1.50) and live spermatozoa (80.25% ± 13.45%). There was no significant difference in semen characteristics between the three collection methods. The percentages of live spermatozoa were significantly different, suggesting better samples from captive compared to confiscated animals. However, there was no significant difference in spermatozoa kinetics between the captive and confiscated samples, suggesting the potential of utilizing confiscated individuals for gamete recovery to conserve the genetic pool of pangolins. All three methods of semen collection were successfully performed in pangolins and should be considered; however, electroejaculation remains the most consistent method of obtaining semen from the species.

A Gas chromatography-mass spectrometry (GC/MS) method was developed and validated for the quantitation of the antimalarial drug, nanoformulated Primaquine (PQ), in whole blood and plasma. The analyte was extracted using a protein precipitation method followed by chromatographic separation on a Waters Xterra, RP C8, 2.5µm, 50mm x 4.6mm analytical column with a mobile phase consisting of A: 0.5% Formic acid in 20mM NH4COOH, B: Methanol pH adjusted to 3.0 with FA at a ratio of 3:7 (v/v), delivered at a constant flow rate of 0.5 ml/min. Mefloquine (MEF) was used as the internal standard. Compound reaction monitoring was performed using 260.4 Da for precursor ion and 175. 2 and 379.2 Da for product ions for the quantification of PQ and 379.2 Da for precursor ion and 175.2 and 379.2 Da for product ions for the quantification, respectively. Calibration curves were constructed over the concentration range 16.7–4300 ng/ml. The mean intra- and inter-assay accuracy values for the analysis of PQ in WB was 104% (%CV = 5.6) and 98.6% (%CV = 5.7), respectively. The mean intra- and inter-assay accuracy values for the analysis of PQ in plasma was 92.7% (%CV = 3.7) and 93.7% (%CV = 5.4), respectively. No significant matrix effect was observed during the method validation. The validated method was applied to an absorption study in mice, to determine and compare PQ concentrations in whole blood and plasma samples. Results of the statistical analysis using a linear mixed effects growth curve model concluded that there was no significant difference (p-value = 0.688) between WB and plasma PQ concentrations. This method utilizes a small sample volume of 20 µl, facilitating low blood collection volumes and a short chromatographic run time of 3 min which allows for high sample through put analysis.
