Background: The neurodevelopmental conditions known as autism spectrum disorders (ASDs) start in early childhood and last the entirety of a person's life. They are characterized by distorted social interaction, difficulties communicating, and repetitive, stereotypical behavior. Objective: This study sought to evaluate general practitioners (GPs)' attitudes and knowledge of ASDs and related factors at Gondar University Hospital. Methods: An institutional-based cross-sectional study design was used. Using a convenience-sample method, three-hundred sixty individuals were chosen for this study. Data were collected using a self-administered questionnaire. The GPs who took part in this survey were characterized by descriptive statistics. The relationship between the dependent variables (knowledge and attitude) and the sociodemographic characteristics was examined using an independent two-sample t-test and Pearson correlation analysis. The Statistical Package for the Social Sciences Version 25 was used for all data analyses. Results: In this study, the GPs had an average age of 31.82 years, with an average of 18 years since graduation and 16 years of practice. Participants' average overall knowledge and attitude scores on autism were 15.83 (SD = 3.27) and 29.54 (SD = 3.21), respectively, both falling within the moderate range. Using an independent t-test, we found a significant difference (p < 0.001) between the attitudes of male and female GPs regarding autism. The study also identified weakly significant correlations between GPs' age and their attitudes toward autism (r = 0.271⁣^∗∗, p < 0.001) and between years of practice and attitudes (r = 0.105⁣^∗, p=0.046). However, no significant correlations emerged between GPs' knowledge and their age, years since graduation, or years of practice (r = 0.069, p=0.194; r = 0.069, p=0.193; and r = -0.053, p=0.312, respectively). In addition, we observed a weakly significant association (r = 0.004⁣^∗∗, p < 0.001) between GPs' knowledge and their attitudes about autism. Conclusion: Based on their total scores, the participants had a moderate level of knowledge and attitudes toward autism. There was a favorable correlation found between the study subjects' attitudes regarding autism and their age, as well as their practice year. Furthermore, a clear correlation was observed between GPs' attitudes and their understanding of autism.

Background: Skin wounds, whether medically or incidentally induced, are always at a risk of becoming infected, but the infection risks are greater when the wounds are recovering under ischemic, poorly perfused conditions. Staphylococcus aureus, which frequently infects cutaneous and soft tissue, can infect to a greater extent when wounds are poorly perfused. Bad as this may be, both MSSA and MRSA strains of S. aureus can cause severe infections, with MRSA being considered more aggressive.

Methods: In this study, we used a lagomorph ear excisional wound model to initially test the influence of partial ischemia on uninfected wound healing. We then subsequently test the same ischemic injury model under an active MSSA infection and compared these wounds against normally perfused MSSA-infected wounds. Lastly, we test whether differences in healing exist between MSSA-infected and MRSA-infected wounds, both under the same ischemic model.

Results: The data suggest that partial ischemia considerably reduces healing of noninfected wounds (epithelial gap P=^∗∗∗∗, granulation gap P=^∗∗∗, and granulation area P=^∗∗∗∗). Similarly, partial ischemic wounds coupled with MSSA infection display healing impairments against likewise-infected wounds healing under normal perfusion (epithelial gap P=^∗, granulation gap P=^∗, and granulation area P=^∗∗). No significant differences were observed between MSSA-infected and MRSA-infected wounds healing under ischemia.

Conclusion: The data produced quantitative differences in healing under various conditions consequent to ischemia and S. aureus infection. Although it is well recognized that ischemia and infection adversely influence healing, by testing these conditions, we determined the detrimental magnitude such circumstances inflict on skin healing, thereby providing a relative reference to compare and gauge when met with similar conditions clinically.

Introduction: Obesity, a pressing global health issue worldwide, contributes to risk factors such as hypertension and dyslipidemia, creating an unfavorable cardiovascular environment and increasing the likelihood of adverse cardiac events. His study aims to assess the impact of obesity on various cardiovascular parameters.

Methods: A cross-sectional analysis was conducted at a Heart Center, focusing on adults admitted for suspected heart diseases. The dataset included information on demographics, clinical history, laboratory results, and echocardiography. Descriptive analysis and multiple linear regression were employed using IBM SPSS Statistics version 26.

Results: The study of 105 individuals with suspected heart diseases revealed prevalent health factors such as hypertension (47.6%) and hyperlipidemia (61%). Body mass index (BMI) averaged 30, indicating a trend toward overweight. Obesity significantly associated with higher systolic blood pressure (SBP, p=0.005) and diastolic blood pressure (DBP, p=0.002), larger cardiac volumes (end-diastolic volume, EDV, p=0.013; end-systolic volume, ESV, p=0.040), and a marginally significant influence on left ventricular end-diastolic diameter (LVEDD, p=0.068). No significant associations were found with left ventricular end-systolic diameter (LVEDS), heart rate (HR), or ejection fraction (EF).

Conclusions: Our study highlights a significant association between obesity and elevated blood pressure, larger cardiac volumes, and a marginal impact on left ventricular end-diastolic diameter. While caution is needed in inferring causation due to the study's cross-sectional nature, these findings underscore the importance of addressing obesity as a potential risk factor for adverse cardiovascular outcomes. Further investigations are warranted to enhance our understanding of the complex interplay between obesity and cardiovascular health.

Background: The incidence of complications and mortality associated with Staphylococcus aureus (S. aureus) bloodstream infections has been increasing significantly, particularly in developing countries where control strategies against this virulent pathogen and its resistance to antibacterial agents are insufficient. The aim of this study was to investigate coagulase typing, the prevalence of toxin genes, and the antibiotic resistance profile of S. aureus isolated from bloodstream infections.

Methods: Antibiotic susceptibility of the isolates was determined by the disk diffusion method. The prevalence of toxin genes was determined using the polymerase chain reaction (PCR) method. Genetic variability of isolates was determined using multiplex PCR based on coagulase gene polymorphism.

Results: Out of 120 strains, 55 (46%) were methicillin-resistant S. aureus (MRSA) and 65 (54%) were methicillin-sensitive S. aureus (MSSA). All isolates were susceptible to linezolid and teicoplanin but showed varying levels of resistance to other antibiotics. The highest resistance was observed for ampicillin (92.5%), gentamicin (69.2%), and amikacin (68.3%). Multidrug resistance was observed in all isolates. PCR analysis revealed a higher prevalence of toxin genes in MRSA (tst: 38%, pvl: 29.1%, eta: 10%, and etb: 4.1%) than that in MSSA. According to the coa typing, the most prevalent types were coa III (29.2%), coa II (26.7%), and coa VI (10%).

Conclusion: The presence of genetic variability and widespread multidrug resistance in our hospitals emphasizes the circulation of various coa types. Therefore, it is crucial to implement antimicrobial stewardship and infection control measures to prevent and control the spread of these strains.

Background: Ineffective nursing documentation practices have been reported to negatively impact patient outcomes and health professional efficiency. On the prevalence of nurses' documentation practices in Ethiopia, several separate studies have been carried out. However, there is no pooled prevalence of nurses' documentation practice. Therefore, this systematic review and meta-analysis aimed to assess the overall prevalence of nursing care documentation practice and related factors in Ethiopia.

Methods and materials: This review only included articles that were published. The main databases were Medline/PubMed, Web of Science, Google Scholar, Scopus, Ethiopian University Repository Online, and the Cochrane Library. Cross-sectional studies that satisfy the criteria and are written in English are included in the review. Using a random effects model, the pooled prevalence of nurses' documentation practices was determined. The funnel plot and the Eggers test were also used to look into publication bias. All statistical analyses were done with STATA version 14.

Result: This review included nine studies with a total of 2,900 participants. The pooled prevalence of nurses' documentation practice in Ethiopia was 50.01% (95% CI: 42.59 and 57.18; I² = 93.8%; and P ≤ 0.001). In terms of subgroup analysis, Addis Ababa had the highest prevalence of nurses' documentation practice at 84% (95% CI: 77.18 and 90.82), while Southern Ethiopia had the lowest at 40.00% (95% CI: 38.10 and 44.90). Nursing documentation practices were statistically associated with the availability of nursing documentation formats, adequate nurse-to-patient ratio, motivation, and training.

Conclusion: This review showed that one in two nurses practiced poor documentation of their daily activities in Ethiopia. Therefore, strict monitoring, evaluation, and supervision of nursing care documentation services are highly recommended for all stakeholders. We strongly recommend improving the identified factors by arranging training for nurses, motivating them, providing adequate documentation formats, and maintaining a nurse-to-patient ratio.

Background: The global threat of COVID-19 has created the need for researchers to investigate the disease's progression, especially through the use of biomarkers to inform interventions. This study aims to assess the correlations of laboratory parameters to determine the severity of COVID-19 infection.

Methods: This study was conducted among 191 COVID-19 patients in Sumeru Hospital, Lalitpur, Nepal. According to their clinical outcomes, these patients were divided into severe and nonsevere groups. Inflammatory markers such as LDH, D-dimer, CRP, ferritin, complete blood cell count, liver function tests, and renal function tests were performed. Binary logistic regression analysis determined relative risk factors associated with severe COVID-19. The area under the curve (AUC) was calculated with ROC curves to assess the potential predictive value of risk factors.

Results: Out of 191 patients, 38 (19.8%) subjects died due to COVID-19 complications, while 156 (81.7%) survived and were discharged from hospital. The COVID-19 severity was found in patients with older age and comorbidities such as CKD, HTN, DM, COPD, and pneumonia. Parameters such as d-dimer, CRP, LDH, SGPT, neutrophil, lymphocyte count, and LMR were significant independent risk factors for the severity of the disease. The AUC was highest for d-dimer (AUC = 0.874) with a sensitivity of 82.2% and specificity of 81.2%. Similarly, the cut-off values for other factors were age >54.5 years, D-dimer >0.91 ng/ml, CRP >82.4 mg/dl, neutrophil >78.5%, LDH >600 U/L, and SGPT >35.5 U/L, respectively.

Conclusion: Endorsement of biochemical and hematological parameters with their cut-off values also aids in predicting COVID-19 severity. The biomarkers such as D-dimer, CRP levels, LDH, ALT, and neutrophil count could be used to predict disease severity. So, timely analysis of these markers might allow early prediction of disease progression.

Introduction: We describe an outbreak of Serratia marcescens (S. marcescens) infection in the neonatal intensive care unit at Women's Hospital in Sinaloa, Mexico.

Methods: In April 2021, an outbreak of S. marcescens infection was identified. A case was identified as any patient who tested positive for S. marcescens and showed signs of an infectious process.

Results: S. marcescens was isolated from the blood cultures of 15 neonates with clinical signs of neonatal sepsis. Statistical analysis showed that all neonates had an invasive medical device. The problem was controlled after hospital hygiene and sanitation measures were strengthened.

Conclusion: The study provides evidence of an outbreak of nosocomial bacteremia due to the cross-transmission of S. marcescens. The findings highlight the need for hospitals to implement strict hygiene measures, especially regarding hand washing, to prevent future outbreaks.

Rates of obesity have risen over the past few decades. Subsequently, the popularity of the pharmaceutical weight-loss drug market has grown over the past few years to meet growing demand. Among the most commonly prescribed drugs for weight management, many are glucagon-like peptide-1 receptor agonists (GLP-1 agonists) which are also utilized for the management of type 2 diabetes. There is a substantial and growing body of research comparing the efficacy of different clinical trials and examining long-term safety. This literature review examines the rise of off-label prescribing practices in the management of weight, with a focus on GLP-1 agonists. Physicians and patients should be aware of the unique aspects of existing treatment options, the impacts of off-label prescribing, and the effects of these medications. This review emphasizes the importance of informed decision-making, as well as the need for further research to guide future clinical practice.
