ABSTRACT

Sperm cryopreservation is a rather complex process that needs to be adapted to wild and domestic bird species to ensure adequate efficiency. This study aimed to determine the usability of different cryoprotectants in the cryopreservation of Gloster canary sperm. For this purpose, sperm samples were collected from 12 2-year-old male Gloster canaries three times a week using cloacal massage for 4 weeks. After individual evaluation, sperm samples from the canaries were combined. Mixed sperm were divided into two groups in the study. Overall, 8% dimethyl sulfoxide (DMSO) and ethylene glycol (EG) were used as cryoprotectants. Sperm samples were drawn into straws after adding Dulbecco’s Modified Eagle Medium (DMEM) extender with high glucose ratio and two different cryoprotectants in a 1:1 ratio and frozen to -80°C with liquid nitrogen vapour and then stored in liquid nitrogen at -196°C. Frozen-thawed semen samples were evaluated regarding motility, vitality, plasma membrane integrity (hypoosmotic swelling test [HOST]), density and abnormal spermatozoa rate. The highest motility value after freezing and thawing was determined in the EG group with 31.667% ± 4.773%. In addition, vitality, plasma membrane integrity and normal sperm morphology were statistically significantly higher in the EG-frozen group, whereas head and tail abnormality was low (p < 0.05). This study determined that a DMEM extender containing 8% EG was more advantageous than a DMEM containing DMSO regarding spermatological parameters and could be used for long-term storage of canary sperm.

ABSTRACT

BACKGROUND: Understanding the nature of inflammatory responses in cats with bacterial and viral infections is essential for accurately managing the infection. This study aimed to investigate the diversities of inflammatory responses between bacterial and viral infections in cats to figure out their role in the pathophysiology of these infections.

METHODS: Seventy-five owned cats were included in the study. The evaluations were performed based on three groups: healthy control, bacterial infection group (those with bronchopneumonia and gastrointestinal tract and urinary tract infections) and viral infection group (21 with feline coronavirus [FCoV], 3 with feline leukaemia virus [FeLV] and 1 with feline calicivirus), each containing 25 individuals. Total and differential leukocyte counts, C-reactive protein (CRP), transforming growth factor beta (TGF-β), interleukin-6 (IL-6), tumour necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-10 (IL-10) concentrations were assessed in the blood samples collected from sick and healthy animals.

RESULTS: No statistically significant difference was noted in serum TNF-α, IL-1β and IL-10 concentrations of the infected cats (p = 0.996, p = 0.160 and p = 0.930, respectively). Serum TGF-β concentration in the viral infection group was reduced compared to the healthy control (p = 0.001). In contrast, WBC count and IL-6 and CRP concentrations were increased in the cats with bronchopneumonia, gastrointestinal tract infections and urinary tract infections compared to the healthy control and viral infection groups (p = 0.001, p = 0.001 and p = 0.001, respectively).

CONCLUSION: This study revealed significant differences between bacterial and viral infections regarding the fashion of inflammatory responses in cats, and the relevant data will undoubtedly contribute to the management and control of feline infectious diseases, rendering the development of novel therapeutic strategies.

ABSTRACT

The guinea fowl (Numida meleagris) holds significant agricultural importance in Ghana, particularly in the Northern, Upper East and Upper West Regions. Despite their economic and cultural significance, guinea fowls face a potential threat from avian influenza, a global concern for its adverse impact on poultry populations. This study assessed the seroprevalence of the virus in mature guinea fowls in the Upper East Region. A cross-sectional survey was conducted in three districts within the Upper East Region from April to June 2023. Blood samples were collected from 397 guinea fowls that are over 4 weeks old, and seroprevalence was determined using ID Screen Influenza A Antibody Competition Enzyme-linked immunosorbent assay (ELISA). The study analysed demographic factors such as sex, age and source of birds, employing statistical methods to establish associations. Among the sampled guinea fowls, 24.7% tested positive for avian influenza antibodies, whereas 75.3% were seronegative. Age did not show statistically significant associations with seroprevalence, but intriguing patterns were observed. Adult guinea fowls exhibited higher seroprevalence (23.7%) compared to growers (1.0%). The source of birds showed no significant association, but birds from slaughter points demonstrated higher seroprevalence (11.6%) compared to households (5.0%) and live bird markets (8.1%). In conclusion, the study underscores the importance of monitoring avian influenza in guinea fowls to implement effective control measures. The presence of antibodies suggests guinea fowls may contribute to virus transmission in the Upper East Region. The study recommends ongoing nationwide surveillance to assess the true prevalence of avian influenza in guinea fowls across Ghana.

ABSTRACT

OBJECTIVE: To conduct a systematic review and meta-analysis to assess the impact of transcranial electrical stimulation (TES), proposed as a potential therapy for post-stroke dysphagia, on swallowing function in stroke survivors.

METHODS: The PubMed, Embase, Web of Science, and Cochrane Library databases were searched for relevant studies on TES for post-stroke dysphagia. Search results were reviewed following PRISMA guidelines, and the following data were extracted from included studies: study characteristics, demographics, and outcomes. Bias was assessed using the Cochrane tool. Heterogeneity and effect sizes were analysed using I² statistics and appropriate effects models. The study protocol was registered with PROSPERO (registration No. CRD42024578243).

RESULTS: Six randomized controlled trials met the inclusion criteria (I² = 0.0%). The meta-analysis indicated a significant improvement in dysphagia with TES (standardized mean difference [SMD] 0.43, 95% confidence interval [CI] 0.13, 0.73). Subgroup analysis suggested that low-intensity TES was effective (SMD 0.46, 95% CI 0.09, 0.82), whereas high-intensity TES showed no significant improvement (SMD 0.37, 95% CI -0.17, 0.91). No publication bias was detected.

CONCLUSION: TES may improve swallowing in stroke patients, with potential benefits from low-intensity protocols.

ABSTRACT

OBJECTIVE: Clinical studies indicated a link between DTI imaging characteristics and epilepsy, but the causality of this connection had not been established. Therefore, we employed the Mendelian randomization analysis method to determine the causal relationship between DTI imaging characteristics and epilepsy.

METHOD: We used Mendelian randomization analysis to identify the causal relationship between brain structure and the risk of epilepsy. GWAS data of DTI phenotypes, focal epilepsy, and genetic generalized epilepsy (GGE) were utilized in the analysis.

RESULTS: Our study found that DTI imaging phenotypes had a causal risk relationship with epilepsy. These phenotypes had a statistical impact on the risk of epilepsy seizures. There were differences in DTI phenotype causality between GGE and focal epilepsy, which were associated with the clinical phenotype differences of the two types of epilepsy.

SIGNIFICANCE: Our study demonstrated that the diagnosis of subtypes could be assisted by comparing the differences in DTI phenotypes of specific brain regions. This meant that by studying the changes in brain regions before the onset of epilepsy, we might be able to intervene in epilepsy at an earlier stage.

PLAIN LANGUAGE SUMMARY: Our study used Mendelian randomization to explore the causal relationship between brain structure, as seen in DTI imaging, and epilepsy. We found that specific DTI phenotypes are linked to an increased risk of epilepsy seizures, with notable differences between genetic generalized epilepsy and focal epilepsy. This suggested that analyzing DTI phenotypes could help in diagnosing and potentially intervening in epilepsy earlier by finding brain changes before seizures begin.

ABSTRACT

In forensic handwriting analysis, it is crucial to understand the relative frequencies of findings relevant to the specific author, especially when using statistical methods. These are factored into the likelihoods used to determine the probabilities for the different authorship hypotheses. However, if ad hoc writings are included in the comparison materials, the representation of a comparison writer’s habits can be distorted. An overrepresentation of certain creation time points can be avoided by treating ad hoc series of comparison writing samples as internally homogeneous agglomerates, incorporating only a single value per series into the average relative frequency of a given finding for a comparison writer. Additionally, the proposed approach produces finding counts largely independent of the length of the handwriting sample, which has a positive impact on the efficiency and cost-effectiveness of the expert evaluation.

ABSTRACT

BACKGROUND: An evidence gap still exists regarding the efficacy and safety of tegoprazan in Chinese patients with erosive esophagitis (EE) in China. This study aimed to verify the efficacy and safety of tegoprazan vs. esomeprazole in patients with EE in China.

METHODS: This study was a multicenter, randomized, double-blind, parallel, active-controlled, non-inferiority phase III trial of patients with EE randomized 1:1 to tegoprazan 50 mg/day vs. esomeprazole 40 mg/day. This study was conducted in 32 sites between October 24, 2018 and October 18, 2019. The primary endpoint was the cumulative endoscopic healing rate at week 8. The secondary endpoint included endoscopic healing rate at week 4, changes in the reflux disease questionnaire (RDQ) and gastroesophageal reflux disease health-related quality of life (GERD-HRQL) scores, and symptom improvement.

RESULTS: A total of 261 patients were randomized: 132 to the tegoprazan group and 129 to the esomeprazole group. The cumulative endoscopic healing rate at 8 weeks in the tegoprazan group was non-inferior to that of the esomeprazole group (91.1% vs. 92.8%, difference: -1.7, 95% confidence interval [CI]: -8.5, 5.0, P = 0.008). There were no statistically significant differences in the changes in RDQ (total, severity, and frequency) and GERD-HRQL scores between the two groups (all P >0.05). The percentages of days without symptoms, including daytime and nighttime symptoms based on patients’ diaries, were similar between the two groups (all P >0.05). In the tegoprazan and esomeprazole groups, 71.5% (93/130) and 61.7% (79/128) of the participants reported adverse events (AEs), 2.3% and 0 experienced serious AEs, while 70.0% and 60.2% had treatment-emergent AEs, respectively.

CONCLUSION: Tegoprazan 50 mg/day demonstrated non-inferior efficacy in healing EE, symptom improvement, and quality of life, and it has similar tolerability compared with esomeprazole 40 mg/day.

ABSTRACT

Introduction: Patients are at risk of hospital readmission after kidney and liver transplantation due to the complexity of posttransplant care. Currently, clinical practice relies on providers’ prediction since there is a lack of specific strategies. However, the accuracy of clinicians’ ability to predict readmissions using clinical judgment alone is unknown. Research Question: What is the accuracy of clinicians’ ability to predict readmissions after transplantation using clinical judgment alone? Design: In 2019, clinical providers at a large, urban transplant center were electronically surveyed. Primary surgeons, nephrologists, transplant pharmacists, hepatologists, and nurses were asked, within 24 h of any kidney or liver transplant recipient discharge, to predict whether a patient would be readmitted within 30 days, and the suspected causes of readmission. Prediction accuracy was assessed by sensitivity, specificity, positive and negative predictive value, and F-score. Kappa scores were calculated to assess agreement between transplant surgeons and other providers. Results: Overall, N = 34 unique providers were surveyed about 148 kidney and 63 liver transplant recipients, and 27.0% of kidney recipients and 25.4% of liver recipients were readmitted within 30 days. The positive predictive values were low among clinical providers, ranging from 0.25 to 0.55. Agreements between providers were weak, but higher among kidney transplant providers (range: 0.42-0.44) than for liver transplant providers (range: -0.02-0.26). Conclusion: Clinical judgment alone to predict readmission among transplant recipients may not be sufficient and a combination of clinicians’ predictions, multitiered discharge surveillance strategies and data-based predictive models may better identify high-risk patients and guide interventions to reduce readmission.

ABSTRACT

Background: Nurses who provide person-centered care even after death must possess essential competencies to perform their duties effectively. Therefore, it is imperative to develop educational programs to enhance the capabilities of new nurses in care after death. Objective: To develop a care after-death mentoring program that includes an augmented reality (AR) end-of-life experience for new nurses and to describe its effectiveness. Design: A quasi-experimental pre- to post-test design was followed to evaluate program outcomes. Setting/Participants: The participants (n = 18) were nurses with <12 months of experience working at a tertiary general hospital in South Korea. Measurements: A pre-post survey was conducted on comfort in bereavement/end-of-life care, death anxiety, and compassion competency. Data were analyzed using the SPSS program, employing descriptive statistics and paired sample t-tests. Results: Significant improvements were observed in both comfort during bereavement/end-of-life care and compassion competency (t = -8.43, p < 0.001; t = -4.90, p < 0.001). Conclusions: This study demonstrated enhancements in participants’ comfort levels regarding bereavement and end-of-life care, as well as their ability to exhibit compassion after participating in the program. Consequently, it was confirmed that simulation-based care after-death mentoring education utilizing an AR app helped enhance the capabilities of new nurses.

ABSTRACT

Introduction: The sleeve gastrectomy (SG) often requires conversion to Roux-en-Y gastric bypass (RYGB) due to gastroesophageal reflux disorder (GERD). Many postbariatric patients seek body-contouring surgery such as abdominoplasty to remove unwanted skin and fat. Although the number of abdominoplasties performed in postbariatric patients is increasing each year, the number of conversion surgeries is increasing in accordance. This study evaluates the impact of abdominoplasties in patients with prior SG on the development of GERD and the need for conversion to RYGB. Methods: A retrospective study was conducted with 630 patients who underwent conversions from SG to RYGB at our institution between January 2014 and December 2023. Outcomes were stratified for comparison between patients with GERD as an indication for conversion and patients with inadequate weight loss as an indication for conversion. Between the two groups we compared the number of patients with post-SG abdominoplasty and the number of hiatal hernias (HH) seen during conversion surgery. A logistic regression analysis was performed to identify factors independently associated with GERD. Results: There was a statistically significant higher number of abdominoplasties in patients who underwent conversion to RYGB for GERD (29 patients, 8.6%) compared to inadequate weight loss (12 patients, 4.1%), P value .034. However, these patients also had statistically significantly more HH (98 patients, 28.9%) compared to patients with inadequate weight loss as an indication for conversion (46 patients, 15.8%), P value <.001. In the logistic regression comparing these two variables, only the presence of HH seen during surgery was found to be a significant predictor of GERD (odds ratio 2.7, confidence interval 1.7-4.1, P < .001). Conclusion: Our data shows that abdominoplasty surgery does not directly influence the development of GERD in post-SG patients. However, the presence of HH in this population significantly impacts the development of GERD, often necessitating conversion to RYGB.
