Background: Chest tube infection is one of the complications of the tube thoracostomy. Infectious complications may develop in 2% to 25% of patients who undergo thoracotomy tube placement. The use of prophylactic antibiotics to prevent infections associated with thoracostomy tubes remains a subject of debate. Current practices in managing infections related to tube thoracostomy are hindered by the lack of comprehensive and localised data on the microbial profile and their resistance patterns. Objective: To determine the prevalence of thoracostomy tube infections and associated clinical characteristics among patients treated with a thoracostomy tube at KCMC Zonal Referral Hospital. Methodology: Prospective cohort study done at KCMC Zonal Referral Hospital. Include all patients undergoing thoracostomy tube insertion from September 2024 to April 2025. Results: A total of 84 patients underwent tube thoracostomy during the study time. Of these 22 (26.2%) developed SSI. Out of the 22 samples collected, 17 (77.3%) had positive culture results. The most commonly identified pathogens were Pseudomonas aeruginosa (41.2%) and Staphylococcus aureus (29.4%). The highest overall susceptibility was observed with amikacin, effective against 10 (58.8%) of the tested organisms. The most common resistance was observed against ceftazidime (56.3%) and piperacillin-tazobactam (50.0%). Prolonged chest tube duration (>7 days) was the strongest independent predictor of tube thoracostomy infection. Conclusion: This study revealed a high prevalence of tube thoracostomy infection. Prolonged tube duration and admission to a non-surgical ward care emerge as key risk factors for SSI. These findings underscore the importance of limiting chest tube duration when clinically feasible and ensuring optimal postoperative care environments to minimise the risk of infection.

BackgroundFerroptosis has emerged as a promising therapeutic target in IRI. However, it remains largely unclear how and when this iron-dependent regulated cell death manifests during IRI. Therefore, we explored malondialdehyde (MDA), a byproduct of lipid peroxidation, and glutathione peroxidase 4 (GPX4), as a marker of redox capacity, in multiple IRI models. With this explorative study, we aimed to uncover MDA dynamics in renal and hepatic IRI, which could provide valuable insights for future internal studies. MethodsHistorical plasma and tissue samples from rat and porcine models of renal and hepatic IRI were selected based on varying conditions of ischemic injury, reperfusion and perfusion. MDA was measured using a colorimetric assay with N-methyl-2-phenylindole, methanol, acetonitrile and hydrochloric acid and quantified at 595 nm. GPX4 protein concentrations were investigated using standard western blotting. ResultsIn rat clamping models, plasma MDA concentrations revealed no difference between control and IRI settings. However, an increasing trend could be observed in tissue samples after IRI. Similarly, a decrease in tissue GPX4 concentrations was observed after IRI. In porcine studies, MDA concentrations were increased during reperfusion of kidneys exposed to prolonged warm ischemia and livers exposed to short periods of cold ischemia. Dynamic preservation could attenuate MDA concentrations. ConclusionWe found that MDA and GPX4 are affected within the first hours after reperfusion, stressing the need for early sampling in studies focusing on characterizing ferroptosis. Moreover, MDA dynamics during organ perfusion revealed an increased vulnerability of ischemic organs to lipid peroxidation and a potential protective effect of dynamic preservation. These preliminary results should be confirmed in studies focusing on ferroptosis characterization, as notable observations regarding sample age and storage conditions and experimental design limit the validity of this study.

Background: Spotted fever is caused by spotted fever group rickettsiae (SFGR) belonging to the genus Rickettsia. Transmission to humans is primarily via the bite of infected ticks. Being a vector-borne disease, the occurrence of spotted fever is related to factors that allow the vector to thrive. This spatio-temporal analysis gives an insight into the distribution of cases and correlation with seasonality. Methodology: A suspected AFI patient was considered spotted fever positive if either serology (ELISA/IFA) or molecular assay (Nested PCR/qPCR) was tested positive. Demographic data of confirmed cases were included for the analysis. Results: In the 18-year dataset, a total of 2153 suspected patients were tested for spotted fever, of which 516 (24%) were positive. On spatio-temporal analysis, Vellore district reported 39.9% of cases, Chittoor 38.8%, Tirupattur 12.5%, Ranipet 4.5%, and Tiruvannamalai 4.3%. Maximum spotted fever cases were reported between the months of September to March, with a peak in January. Children below 10 years and housewives were at risk of spotted fever. Conclusion: The findings of this retrospective analysis highlight the importance of considering spotted fever group rickettsioses in patients presenting with acute undifferentiated febrile illness, particularly children aged <10 years, from areas with higher spatial clustering, during or following the monsoon season.

Schizophrenia (SCZ) and type 2 diabetes mellitus (T2DM) are common comorbid disorders that severely impair patient prognosis and quality of life. This study aimed to explore the association between the methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism and MTHFR promoter methylation in patients with comorbid SCZ and T2DM. A total of 120 participants were enrolled from Liaocheng Fourth Peoples Hospital between January 2025 and June 2025, comprising 30 subjects in each of the four groups: SCZ group, T2DM group, SCZ-T2DM comorbid (SCZ+T2DM) group, and healthy control (CTL) group. Corresponding primers were designed for genetic analysis, and methylation-specific PCR (MSP) was performed to detect the methylation level of the MTHFR promoter. Genotype distribution of the MTHFR C677T polymorphism was consistent with Hardy-Weinberg equilibrium (HWE) (p>0.05). The C677T polymorphism was significantly associated with an elevated risk of SCZ and T2DM comorbidity (p<0.05). Notably, the methylation rate of the MTHFR promoter in the SCZ+T2DM group (95.00%) was not significantly higher than that in the CTL group (90.00%) (p>0.05). In conclusion, the MTHFR gene may serve as a susceptibility gene for SCZ-T2DM comorbidity, whereas MTHFR promoter methylation is not associated with the pathogenesis of this comorbid condition. These results indicate that genetic variation in MTHFR, rather than promoter methylation, contributes critically to the comorbidity of SCZ and T2DM in the Han Chinese population. Our findings may provide novel molecular insights into their shared pathophysiology and inform future clinical strategies for patients with this complex phenotype.

Introduction: Solitary plasmacytomas (SP) are rare neoplasm of localised proliferation of clonal plasma cells. It can be classified based on site of involvement and bone marrow involvement. It is an indolent disease in the majority of patients. Primary modality of treatment is radiotherapy and surgical excision. Materials and methods: This was a retrospective audit of SP who were treated and followed up at a tertiary care center in eastern India from January 2012 to December 2025. Patients who has solitary plasma cytoma with more than 10% plasma cells, POEMS syndrome, have been excluded from analysis. Results: We identified 46 patients of SP. The median age of the studied population was 53 years (23-75 years). Males were more commonly affected than females (M:F=2.2:1). Most common chief complaints were bony pain (67.4%). SBP was seen in 39 (84.8%) cases whereas SEP was seen in 7 (15.2%) cases. Vertebra was the most common site of involvement (61.4%). Median M band concentration 0.24 g/dL (0.1 to 1.95 gm/dL). IgG was the most common isotype accounting for 60.6% cases. Six cases (13%) had minimal bone marrow involvement. The majority of the patients received local radiotherapy (89.1%). With a median follow up of 5.4 years (95% CI: 1.8 - 9.0), median OS was not reached, median PFS was 9.22 years (95% CI: 5.8-12.6), median time to next treatment (TTNT) was 9.86 years (95% CI: 6.8 - 12.9). Conclusion: Solitary plasmacytoma commonly affects young males. Bones are more commonly affected than extramedullary sites. SP has a lower rate of progression and excellent prognosis when treated with local radiotherapy.

Hemoglobinopathies are inherited disorders of hemoglobin, most notably sickle cell anemia and thalassemia. These conditions result from mutations in the globin genes, leading either to structural abnormalities in the globin chains or to reduced synthesis of normal globin chains. Hemoglobinopathies is a worldwide health problem according to the World Health Organization; it affects mostly the indigenous Tharu groups in Nepal. Both the global and local rates of illness and death associated with these diseases are on the rise. The objective of this study was to assess the presence of hemoglobinopathies and common mutations of the beta-globin gene within the Tharu population in western Nepal. A cross-sectional study of 1,400 Tharu individuals was conducted among individuals obtained through hospitals within the Banke district, Bardiya district, and Kailali district in western Nepal. A thorough hematological analysis was done with the use of a Sysmex XN-350 analyzer. Hemoglobin variants were detected via high-performance liquid chromatography (HPLC). The molecular characterization of the seven most common mutations of {beta}-thalassemia was performed on a subset of 20 confirmed cases by using a real-time PCR kit.The total number of cases diagnosed with hemoglobinopathies was 14.43% (n=202 out of 1,400). Sickle cell trait (HbAS) was reported as the most prevalent type of Hemoglobinopathies (8.50% of population), followed by {beta}-thalassemia trait (4.00%). In addition to these disorders were sickle cell disease (HbSS), HbE trait, and compound heterozygous states. Hematological parameters differed significantly across types of hemoglobinopathies, and the patterns of microcytic, hypochromic, and hemolytic anemia were also distinct. Commonly documented symptoms included fatigue and joint pain (42.5% and 23.1%, respectively). Molecular characterization of {beta}-thalassemia cases demonstrated that most individuals were compound heterozygotes with IVS1-6 (T>C) as the most prevalent variant. The research identified that the Tharu population in western Nepal has a significant burden of hemoglobinopathies (especially sickle cell trait and {beta}-thalassemia), highlighting the requirement for appropriate screening programs, genetic counseling and public health strategies to help manage and prevent these conditions within this particular region.

ABSTRACT Background: Student nurses satisfaction with their academic programme is crucial for measuring the success of nursing training institutions. However, in Ghana, studies on student nurses' satisfaction have mainly focused on clinical learning, neglecting their satisfaction with the academic programme as a whole. This study therefore, assessed the predictors of student nurses satisfaction with their academic programme. Methods: A quantitative cross-sectional study design was used in the study. A systematic random sampling technique was employed to recruit 241 student nurses from two Nursing Training Institutions in the Eastern Region of Ghana. The Nursing Student Satisfaction Scale (NSSS) was used for data collection and data was analyzed using Statistical Package for Social Sciences (SPSS) version 27 software. Results: Correlation analysis revealed significant positive associations between satisfaction with curriculum (r = 0.583, p<0.001), faculty role (r = 0.650, p<0.001), social interaction (r=0.680, p<0.001), and overall satisfaction with the academic programme. After adjusting for the school of the student nurses, the school environment (B=0.354, p =0.000) and social interaction (B=0.291, p=0.001) emerged as significant predictors of student nurses' satisfaction with their academic programme. Conclusion: The study highlights the need for interventions to enhance the school environment and foster positive social interactions to improve student nurses satisfaction with their academic programme.

BackgroundSexual violence (SV) is a major public health problem with far-reaching consequences; however, adolescent survivors rarely seek help. This underestimates the prevalence of SV and undermines prevention and response efforts. This study was conducted to determine the prevalence and reporting of sexual violence among adolescents in Ibadan, Nigeria. MethodsBetween September and October 2021, a cross-sectional study was conducted among 360 in-school adolescents in Ibadan South-West local government area, Nigeria. Adolescents were selected using multi-stage sampling. Information on experience and reporting of sexual violence was obtained with the aid of an interviewer-administered questionnaire. Data were analysed using descriptive and inferential statistics at p[&le;]0.05 level. ResultsRespondents mean age was 14.6{+/-}1.7 years, and 50% were female. Thirty-five per cent reported at least one incident within the past 12 months. Forms of sexual violence experienced included unwanted sexual touch (25.6%), forced sex (19.2%), attempted rape (15.2%), and suggestive comments (9.6%). Seventy per cent of adolescents who experienced sexual violence did not report to anyone; reasons included fear of getting in trouble (46.6%), thinking it was not a problem (31.8%), feeling it was their fault (30.7%), and embarrassment for self/family (27.3%). Adolescents who were closer to their mothers and younger adolescents were more likely to report their experience of sexual violence (p=0.006 and p=0.038, respectively). ConclusionSexual violence is common among in-school adolescents in Ibadan, yet reporting remains low. This study highlights the need to strengthen prevention and address barriers to reporting among adolescent survivors. Key MessageO_ST_ABSWhat is already known on this topicC_ST_ABSSexual violence has physical, psychological, and social consequences on the health and well-being of adolescent survivors, and low levels of reporting and help-seeking contribute to these consequences. What this study addsThis study provides evidence on the prevalence and reporting patterns of sexual violence among adolescents in Ibadan, Nigeria. It highlights key barriers and facilitators of reporting. How this study might affect research, practice, or policyThis study provides information about factors at individual, relationship, societal and policy levels that are associated with reporting and help-seeking among adolescent survivors of sexual violence in Ibadan, Nigeria. This highlights the importance of training stakeholders, such as parents, teachers, health workers, other caregivers and the adolescents themselves, on responding to sexual violence experience and reporting. It underscores the need for improved adolescent-friendly services, policy implementation and collaboration across families, schools, communities and states to address sexual violence.

Digital pathology, coupled with advanced image recognition algorithms, represents a transformative frontier in histopathological diagnosis. This sub-Saharan African laboratorys exploratory study investigates the application of a Convolutional Neural Network (CNN) model, specifically leveraging the VGG16 architecture with transfer learning, for automated analysis and classification of selected gastrointestinal (GIT) and liver tissue samples, incorporating both routine and specialized staining protocols. The study utilized a dataset comprising 114 samples (18 liver, 96 GIT images) derived from archival formalin-fixed paraffin-embedded tissue blocks at University College Hospital, Ibadan, Nigeria. Specialized staining techniques included Alcian Yellow for GIT mucin visualization and Massons Trichrome for liver fibrosis assessment, alongside conventional H&E staining. Model performance was evaluated using statistical methodologies including Wilson Score confidence intervals (CI), Bayesian probability assessment, and effect size analysis. Results reveal a striking dichotomy in model performance. The GIT tissue model achieved perfect classification accuracy (100% test accuracy) with exceptional statistical significance (Z=10.0, p<0.0001), Wilson CI [96.29%, 99.99%], Cohens h=1.571, and Bayesian probability >99.99%. Conversely, the liver tissue model demonstrated diagnostic failure (42.86% test accuracy), with Z=-1.428, p=0.9236, Wilson CI [33.59%, 52.65%], Cohens h=-0.144, and Bayesian probability of 7.64%. This performance divergence correlates with training data availability, as the liver dataset fell far below empirically established thresholds (>100-200 samples) for reliable classification. The liver models failure reveals limitations in transfer learning with insufficient data. These findings underscore critical implications for AI-enhanced digital pathology, demonstrating potential deployment of the GIT model as a promising one that supports tissue-specific model development.

A systematic review and meta-analysis of sleep studies in schizoaffective disorder were conducted using published articles researched in major databases within the period from inception to December 1, 2025. The sleep parameters: total sleep time, sleep efficiency, sleep latency, wakefulness, REM time and percentage, REM latency, REM density, stage 1, 2, 3 and 4 sleep time and percentage, delta sleep time and percentage, of drug-free schizoaffective patients were analyzed and, where available, compared with case-control data of healthy controls, depressed unipolar patients and schizophrenic patients. Forty studies were identified in the systematic review. Nine case-control studies with 67 schizoaffective patients, 88 schizophrenic patients, 79 healthy controls and 131 depressed patients were included in the meta-analyses. The primary outcome was the standard mean difference. Data were fitted with a random-effects model. Publication bias assessment was checked by Egger's Regression and funnel plot asymmetry. Patients with schizoaffective disorder showed reduced total sleep time, increased sleep latency and wakefulness, along with reduced REM time and shortened REM latency, reduced stage 4 sleep time and percentage compared to healthy controls. Patients with schizoaffective disorder differed from depressed patients only for increased sleep latency, while they did not show any difference compared to patients with schizophrenia. SZA showed a non-significant trend (p=0.08) towards increased REM density compared to SCZ, suggesting the need to better clarify the role of REM density in mood and psychotic disorders.

There is an ongoing Oropouche Fever (OF) outbreak in Brazil since 2024. There are dengue and chikungunya prediction models available, but none to help discriminate dengue, chikungunya, and OF. Objective: This study aims to develop and validate clinical prediction models for dengue, chikungunya, OF. Methods: This study uses surveillance data from Espirito Santo state / Brazil, from 2023-2025. Epidemiological investigations and biological samples were used to conclude cases as either (a) clinical-epidemiologically confirmed, (b) laboratory confirmed, or (c) discarded. The predictors were all data related to signs, symptoms, and comorbidities available in the notification forms. The analysis was performed using random forest regression models, one for each outcome, in development and validation datasets. Results: A total of 465,280 observations were analyzed, 261,691 dengue cases (56.6%), 18,676 chikungunya cases (4.0%), 12,174 OF cases (2.6%), and 179,115 discarded cases (38.6%). All three models had good discrimination and moderate to good calibration after scaling prediction. The models retained from 26 to 16 predictors each. Leukopenia and vomiting were the most discriminatory predictors for dengue, arthritis, arthralgia, and rash were the most discriminatory for chikungunya, and epidemiological features were the most relevant for OF. The dengue, chikungunya, and OF models had ROC AUC of 0.726, 0.851, and 0.896 in the validation set, respectively. Conclusion: This research identified predictors most discriminative between dengue, chikungunya, and OF. We developed and validated predictive models, one for each condition, with moderate to very good performance available at https://pedrobrasil.shinyapps.io/INDWELL/. One may use them in diagnostic work-up and arbovirus surveillance.

Abstract Background: To influence malaria-related behaviours, it is important to understand key behavioural drivers, encourage enablers and address barriers to individuals and communities adoption of interventions to prevent malaria. The capability(C), opportunity(O), and motivation(M) Behaviour(B) model (COM-B model) was used to inform development of perennial malaria chemoprevention (PMC) social, and behaviour change (SBC) message delivered through routine immunization (RI) platform. This paper presents how the COM-B model was used for designing the SBC messages for PMC using the findings from a qualitative study. Methodology The COM-B model provided the theoretical framework for designing the PMC SBC intervention by identifying, capability, opportunity motivation for PMC as well as the barriers, and possible enablers for PMC uptake. A qualitative study was conducted as key source of information. Twelve focus group discussions (FGDs) were conducted with the target audience comprising of mothers of children under two years, pregnant women, men, ward development committee members, community mobilizers and health workers. A total of 120 people participated in the study. An SBC workshop was conducted to develop key messages and content for a community dialogue flipbook and facilitators' guide. Results Knowledge of malaria signs that prompt mothers to seek health care for their children as well as awareness about malaria prevalence and severity, were identified as capabilities that could drive behaviour change, while forgetting the time to visit the health facility was noted as a hindrance. Opportunities and social influencers included spousal support, the positive influence of health workers, accessibility and affordability of the intervention, and the availability of transportation. Motivation was shaped by the perceived seriousness of malaria as a health problem that could lead to the death of children. Fathers were motivated when they observed reduced malaria burden and improved child health, although a lack of perceived urgency remained a demotivating factor for seeking care. Mothers' motivation was strengthened by encouragement from husbands, community mobilisers and health workers. Conclusion The COM-B model provided an effective framework for identifying and developing key messages that informed changes needed to improve capability, opportunities, motivation of individuals and communities towards increased uptake of PMC during PMC pilot study in Osun state Nigeria.

Purpose Diabetic retinopathy (DR) is one of the most important complications of diabetes mellitus (DM), representing the leading cause of blindness among working age adults in developed countries. This study was aimed to investigate the epidemiology and risk factors of DR in patients with diabetes mellitus in a hospital setting in Somalia. Methods The study was an observational, descriptive cross-sectional and hospital-based study and data were collected from January 2023 to May 2023. A structured questionnaire was used to collect relevant demographic and clinical data. Both univariate and bivariate tables were used for analysis. Data analysis included frequency distribution, cross-tabulation, co-relation and association, and statistically significant tests between variables (X2, p-value, and CI). Results A total of 384 DM patients were studied and 76% (n=293) of them had type 2 DM. The average duration of diabetes mellitus was 9.7 SD 6.9 years and the mean age was 47.24 SD 19.36 years (range 18 -100 years old). A majority 66% (n=253) were female, about a third of them had normal body mass index (BMI) (n=172, 44.8%) and 170 (44.3%) had concomitant hypertension. About 51% of the patients (n=197) had DR out of which 17% had non-proliferative diabetic retinopathy (NPDR) (n=67) and 26% had Macular oedema (n=98). Age above 40 years (p=0.020), marital status (P=0.010), employment status (P=0.002) and literacy status (P=0.020) were significantly associated with the presence of DR. Patients aged below 40 had 37% lesser risk of having diabetic retinopathy than patients aged above 40 years. Longer duration of diabetes (p=0.001) and the presence of concomitant cardiac illness (p=0.001) were strongly associated with the presence of diabetic retinopathy. Patients with duration of diabetes more than 10 years had approximately 2 times higher chance of developing DR than those with duration less than 10 years. Conclusion: The very high prevalence of DR (51%) among our patients implies the needs for a good health policy to manage DM and DR patients in Somalia. Effective regular eye screening and treatment for all diabetes patients should get priority.

BackgroundFamily-based HIV index case testing identifies family members with unknown HIV status and links them to care. Data are limited in southern Ethiopia. MethodsA facility-based cross-sectional study was conducted among 377 adults on antiretroviral therapy (ART) in Wolaita Zone, Southern Ethiopia, from November 2022 to May 2023. Participants were selected using systematic random sampling. Data were collected via interviewer-administered semi-structured questionnaire. Multivariable logistic regression identified factors associated with index case family testing. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) were calculated, and statistical significance was declared at p < 0.05. ResultsThe proportion of index case family testing for HIV was 84.9% (95% CI: 81.2- 88.6). In multivariable analysis, urban residence (AOR = 2.8; 95% CI: 1.16-6.75), duration on ART greater than 12 months (AOR = 13.0; 95% CI: 4.6-36.9), disclosure of HIV status to family members (AOR = 5.6; 95% CI: 1.9-16.5), discussion of HIV status with family members (AOR = 6.6; 95% CI: 1.9-23.2), and being counselled by health professionals to bring families for testing (AOR = 6.3; 95% CI: 2.1-19.0) were significantly associated with index case family testing. ConclusionThe prevalence of family-based HIV index case testing in Wolaita Zone was 84.9%, below the national 95% target. Health professionals should strengthen counselling on ART adherence, status disclosure, family discussion, and active referral to improve testing uptake among family members of people living with HIV.

Background Urinary catheterization is a routine procedure after ureteroscopy lithotripsy URSL , but it often causes catheter-related bladder discomfort (CRBD) and urethral pain, which aggravates patients' postoperative discomfort. This study finds out the effect of topical anesthesia on CRBD and urethra pain in patients undergoing ureteroscopy lithotripsy and urinary catheterization. Methods In this study, 330 patients undergoing ureteroscopy lithotripsy enrolled, with 160 cases in the control group and 170 cases in the experimental group. The experimental group divided into two subgroups based on the local anesthetic used: Tetracaine Hydrochloride Gel subgroup and Oxybuprocaine Gel subgroup. Postoperative assessments conducted using CRBD scores and urethra pain numerical rating scale (NRS) score. CRBD and urethra pain NRS scores measured at T0, T1, T2, T3, T4, T5, and T6. Results Compared to the control group, the use of local anesthetics significantly reduced both CRBD scores and urethra pain NRS scores in the experimental group, with the differences being statistically significant (P < 0.01). In male patients, patients who used local anesthetics markedly decreased CRBD scores and urethra pain NRS scores compared to those not receiving local anesthetics, showing statistical significance (P < 0.01), whereas no significant difference followed in female patients. No statistically significant differences found between Rigid ureteroscopy lithotripsy R-URSL and Flexible ureteroscopy lithotripsy F-URSL) regardless of the use of local anesthetics. Within the experimental group, the effects of different local anesthetics were similar, with comparable impacts on CRBD scores and urethra pain NRS scores, and no statistical differences noted. These findings suggest that local anesthetics are effective in reducing postoperative CRBD scores and urethra pain NRS scores, especially in male patients. Conclusion Topical anesthesia following ureteroscopy lithotripsy reduces CRBD scores and urethra pain NRS scores in patients undergoing urinary catheterization, especially in male patients.

Flaxseeds have high nutritive value due to the presence of proteins, lignins (SDG), fatty acids, vitamins, dietary fibers, minerals and carbohydrates. This research was conducted to evaluate the effect of distinct doses of flaxseeds on hematological parameters, immunity and lipid profile of male rabbit. In this research, 60 male rabbits were isolated into four groups, three treatment groups T1, T2 and T3 and a control group T0, with 15 rabbits in each group. The treatment groups were given 4%, 6% and 8% of flaxseeds per daily diet for 45 days. On 15th, 30th and 45th day of experiment, blood samples were collected to examine their hematological parameters. Serum was separated from the collected blood sample to perform ELISA and serum lipid profile test to assess antibody titer and lipid profile of the rabbits respectively. The results indicated a significant reduction in TC, TG, and LDL-C levels in contrast to HDL-C which increased significantly in all treatment groups. Whereas, the statistical analysis of hematological parameters showed an HSD (p[&le;]0.05) in flaxseed treated groups. A maximum level of Hb, WBCs, RBCs, MCHC, MCV, HCT, MCH and differential leukocytes count was recorded in high dose group T3 (8% flaxseeds) followed by medium dose group T2 (6% flaxseeds) and low dose group T1 (4% flaxseeds) respectively. There was a significant rise in antibody titer (p[&le;]0.05) against RHDV (Rabbit Hemorrhagic Disease Virus) comparable to non-treated group. The outcomes illustrated that flaxseeds as nutritional supplement are undoubtedly beneficial to health and prevent various diseases. Study contributionThis research specifically explores how dietary supplementation with flaxseeds, a widely recognized source of omega-3 fatty acids, fiber, and antioxidants, can influence metabolic health and immune function. These findings have significant implications for nutritional interventions aimed at improving cardiovascular health, immune support, and overall well-being, making it highly relevant to the journals readership. The aim of this study was to investigates the dose-dependent effect of flaxseeds on hematological parameters, lipid profile and immunity of male rabbits. Using a controlled experimental design, male rabbits were fed a diet supplemented with varying doses of flaxseeds over a period of 45 days. Key parameters such as total cholesterol, triglycerides, LDL-C, HDL-C, antibody titer, red, white blood cell, platelet counts, Hb, HCT, MCV. MCHC, MCH and differential leukocytes levels were measured to assess the impact of flaxseeds. The results demonstrated that flaxseed supplementation significantly restored lipid profiles by reducing total cholesterol and triglycerides, LDL-C and increasing HDL-C while also enhancing immune function by rising antibody titer and maintaining healthy blood profiles in the subjects.

Culture plays a crucial role in health; family, community, culture, and social conventions all have a significant impact on how an infant with jaundice is treated. Written or unwritten rules govern what parents and the community are allowed to do, which may have a detrimental effect on the neonates care. ObjectivesThe study explored how social expectations affect midwives management of neonatal jaundice at the St Patricks hospital in Maase-Offinso, in the Ashanti region of Ghana. MethodA total of seventeen midwives were sampled purposively using an exploratory descriptive design. Participants were engaged in interviews and focus group discussion after ethical approval was obtained. A semi-structured focus group discussion guide and interview guide was used to collect data. ResultsThe study discovered that the treatment of neonatal jaundice was adversely affected by social pressures, misconceptions, maternal choices, and spiritual views. Mothers and midwives socially approved sunbathing, and there were indications that grandmothers disapproved hospital care for their grandchildren. ConclusionCulture, family and social norms cannot be separated from health especially for the neonate whose means of identification is to belong to a family. Consequently, it is essential to respond to social influences, cultural conventions, and the various cultures of families with a culturally sensitive approach.

Abstract Background: ST-elevation myocardial infarction (STEMI) is reported to be a leading cause of mortality worldwide. While cardiac troponins are the gold standard for myocardial injury detection but creatine kinase-MB (CK-MB) and total creatine phosphokinase (CPK) retain prognostic use in resource-limited settings. Objective: To evaluate the prognostic significance of admission CK-MB and CPK levels in STEMI patients and to assess their association with hematological parameters for integrated risk stratification. Methods: This cross-sectional study enrolled 15 consecutive STEMI patients from the Punjab Institute of Cardiology, Lahore, during January 2024. Comprehensive laboratory analysis including cardiac biomarkers (CK-MB, CPK, troponin-I, LDH), complete blood count, renal function, serum electrolytes, and metabolic parameters, was performed on admission. Pearson correlation and comparative statistical analyses were also conducted to assess the relationships between cardiac biomarkers and hematological indices. Results: The cohort includes 15 patients (mean age 50.1 +/- 12.2 years; 73.3% male). Cardiac biomarker elevation was prevalent: CK-MB was elevated in 12/15 (80%), CPK was elevated in 12/15 (80%), with concordant elevation in 11/15 (73.3%), which indicates extensive myocardial necrosis. Troponin-I showed the highest elevation rate at 13/15 (86.7%). Hematological abnormalities included anemia (60%), WBC elevation (53.3%), and RBC reduction (40%). Random glucose averaged 150.80 +/- 63.55 mg/dL, with 66.7% highlighted the hyperglycemia. Remarkably, electrolyte balance was preserved in all of the patients (0% sodium, potassium, and bicarbonate abnormalities), indicating maintained homeostasis. Pearson correlation analysis revealed a significant correlation between CK-MB and CPK (r = 0.615, p = 0.0126), while correlations between cardiac biomarkers and hematological parameters were weak (p > 0.05). Risk stratification identified 53.3% of patients as high-risk who required intensive management. Conclusions: CK-MB and CPK demonstrate significant concordance and retain prognostic value in STEMI patients, particularly in resource-limited settings where troponin access may be constrained. While troponin-I remains the most sensitive biomarker, combined assessment of conventional cardiac enzymes supports reliable evaluation of myocardial injury. Hematological parameters reflect systemic response but show limited correlation with cardiac biomarkers.

Background/Objectives: This study aimed to evaluate the efficacy and outcomes of operative hysteroscopy for the removal of endometrial polyps and assess the procedure's impact on pain experienced by patients. The research was conducted to determine whether the minimally invasive nature of operative hysteroscopy compromises patient comfort when compared with diagnostic hysteroscopy. Methods: The study was conducted at the Gynecology and Obstetrics Clinic of Ba[g]clar Training and Research Hospital over a period of four months. It included 200 women over 18 years of age who were indicated for hysteroscopy. Operative hysteroscopy procedures were performed without the use of a speculum, cervical dilation, anesthesia, or analgesic agents, emphasizing the procedure's minimally invasive approach. Pain assessment utilized the Visual Analog Scale (VAS). Patients were stratified into two groups--those undergoing operative and those undergoing diagnostic hysteroscopy--to compare outcomes and pain scores. Results: The study found that operative hysteroscopy successfully removed 85.1% of the lesions, primarily polyps. There was no significant difference in pain scores between the operative and diagnostic hysteroscopy groups, indicating that the minimally invasive procedure does not increase patient discomfort. Conclusions: Operative hysteroscopy is an effective and tolerable procedure for the removal of endometrial polyps, with high success in complete lesion removal and without significantly impacting the pain experienced by patients. The findings support the use of operative hysteroscopy as a first-line treatment option for endometrial polyps, underscoring the importance of patient selection and the need for further studies on long-term outcomes related to fertility and recurrence.

Background: Out-of-pocket healthcare expenditure (OOPHE) remains a major challenge to accessing adequate medical service, often discouraging individuals from seeking necessary medical services. The extent of OOPHE in Jigjiga city is unknown. This study aimed to assess the magnitude and associated factors of OOPHE among outpatients visiting public hospitals in Jigjiga city, Somali region, Eastern Ethiopia. Methods: A hospital-based cross-sectional study was conducted among 406 outpatients selected through systematic random sampling from three public hospitals in Jigjiga city. Data were collected through interviews-administered questionnaires and analysed by SPSS version 25.0. Binary and multivariable logistic regression analyses were performed to identify factors associated with OOPHE among outpatients (p < 0.05). Results: Overall, 89.5% of respondents incurred out-of-pocket healthcare payments at the point of service delivery. The mean OOPHE per outpatient was 485.6 {+/-} 349 birr ($3.12 {+/-} $2.24). Female [AOR = 3.38, 95% CI (1.54-7.42)], unmarried [AOR = 5.32, 95% CI (1.77-16.03)], and traveled [&ge;]5 km [AOR = 7.07, 95% CI (1.46-34.29)] and higher educational attainment (college and above) [AOR = 7.07, 95% CI (1.55-32.28)] were independently associated with higher odds of incurred OOPHE. Conclusion: The magnitude of out-of-pocket healthcare payments among outpatients was high. Sex, marital status, educational level, and distance to reach a public health facility were significant predictors of OOPHE. Policy action to reduce OOPHE in this setting should include strengthening and expanding the Community-Based Health Insurance scheme and promoting prepayment mechanisms, such as Social Health Insurance, for formal sector employees, specifically for government employees.
