Introduction: The muscular segments which overlie the epicardial arteries are termed as myocardial bridges and the artery which travels through them are termed as tunnel arteries. These tunnel arteries get compressed during the systolic compression of the heart, thus partially or completely blocking the blood supply to the corresponding areas. Aim & Objectives: To assess the impact of these myocardial bridges on the proximal segment of the myocardial arteries. Methodology: The present study was cadaveric-based cross-sectional study. A total of 22 hearts which showed the presence of myocardial bridges were collected from two sources namely: cadaver dissections, autopsy. The hearts were clean and numbered. This was followed by fixation, dehydration, clearing, embedding, block formation, section cutting and staining. Result: The present study showed that there is a significant thickening in the tunica intima of the proximal to bridge segment of the coronary artery. The present study also noted that there is a marked thinning of the tunica media of the same segment. Conclusion: The present study concludes that there is a marked hyperplasia in the proximal segment of the myocardial bridges under tunica intima.

Various risk factors including blood iron may create coronary artery diseases and lead to myocardial infarction. There are controversies with regard to the impact of blood iron on myocardial infarction. Therefore, the aim of this paper was to investigate the relationship between iron reserves and the intensity of coronary artery stenos is among angiographic candidates in Zanjan, Iran. This was a cross sectional study. Samples were consisted of patients who were hospitalized for diagnostic coronary angiography in hospitals in an urban area of Iran. A convenient sampling method was used to recruit samples via interviews and laboratory examinations for FBS, iron, TIBC, ferritin, creatinine serum, CBC, cholesterol, HDL and LDL. The samples were divided into control and intervention groups. After coronary angiography, the intervention group was evaluated by four different methods including the extent score, stenos is score, vessel score and Duke CAN Index. The samples were consisted of 89 men (60.1%) and 59 women (39.9%). The levels of ferritin (p=0.003) and iron (p=0.002), and transferrin saturation percent (p=0.002) showed significant differences between males and females (p=0.004)

Coronary artery disease (CAD) is a very ordinary health problem around the globe. CAD is affected by numerous factors like diabetes, obesity, smoking, gender, and diet. However, the association of CAD with diet is understudied in our region that’s why our study was aimed to evaluate the effect of diet on CAD incidence. This cross-sectional study was completed among local population of Rawalpindi, Pakistan in almost 6 months from November 2020 to April 2021. People were taken in our study via set criteria. Data was collected by self-structured proforma. Data analysis was performed by applying IBM SPSS version 25. Descriptive statistics were applied for quantitative variables. Statistical tests like Chi-square test and Spearman correlation analysis were applied to know the association, direction, and strength of study variables. Our current study displays overall high prevalence CAD (17.48%) among study population. Mean value of age for study participants was 45.42 with SD of ±8.01years. Prevalence of CAD was more common among females, faster food eaters and fresh fruit and raw vegetables non-eaters. Gender, fast food, and fresh fruits and vegetables were associated with CHD significantly with p-values 0.030, 0.0007, and 0.0006 respectively. Strength and direction for fast food and CAD association was very strong and positive while for association between fresh fruits and raw vegetables and CAD was very strong and negative with correlation coefficient +0.812 and -0.831 respectively. In a nutshell, current study indicates high prevalence of CAD especially among females, fast food eaters and fresh fruits and raw vegetables non-eaters. Higher consumption of fast foods leads to higher incidence of CAD and vice versa while higher consumption of fresh fruits and raw vegetables bring down the incidence of CAD incidence and vice versa. So, we need to create awareness among people about the impact of food on CAD and gender specific interventions for each gender to lower down the CAD incidence.

Background. Khat chewing is a common habit in Yemen despite increased evidence of its negative impact on the cardiovascular system.Aims. We aimed to study the epicardial coronary arteries in khat chewers presenting with myocardial infarction (AMI).Materials and Methods. A descriptive, cross-sectional study was conducted between November 2008 and May 2009 in Yemen. AMI patients who underwent coronary angiogram were enrolled and divided into groups (gp): gp1 (diabetic and khat chewers), gp2 (khat chewers and nondiabetic), and gp3 (diabetic and non-khat users).Results. Of 347 AMI patients 63%, 21%, and 16% were in gp 2, 3, and 1, respectively. Khat chewers were younger in comparison to non-khat users. Group 3 patients were more likely to have multivessel disease, severe left anterior descending (LAD), right coronary artery (RCA) stenosis and total RCA, and left circumflex (Lcx) occlusion compared to other groups. Group 1 patients were more likely to have total LAD occlusion and severe Lcx lesions. In multivariate analysis, age, diabetes mellitus, and smoking were significant independent predictors for significant coronary artery lesions; however, khat chewing did not show such association.Conclusions. Coronary spasm is the main mechanism of AMI in khat chewers. The impact of our finding for risk stratification and management warrants further studies.

Abstract. Background: Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties. Methods: This is a retrospective cross-sectional study design. 20,748 invasive, percutaneous PVI of PAD conducted in the metropolitan area of Hamburg (Germany) were consecutively collected between January 2004 and December 2014. Results: MTD prior to PVI was associated with lower odds of early unsuccessful termination of the procedures (Odds Ratio 0.662, p < 0.001). The proportion of MTD decreased over the study period (30.9 % until 2009 vs. 16.6 % from 2010, p < 0.001) while rates of critical limb-threatening ischemia (34.5 % vs. 42.1 %), patients´ age (70 vs. 72 years), PVI below-the-knee (BTK) (13.2 % vs. 22.4 %), and rates of severe TASC C/D lesions BTK (43.2 % vs. 54.2 %) increased (all p < 0.001). Utilization of MTD was different between medical specialties with lowest frequency in procedures performed by internists when compared to other medical specialties (7.1 % vs. 25.7 %, p < 0.001). Conclusions: MTD prior to PVI is associated with technical success of the procedure. Nonetheless, rates of MTD prior to PVI are decreasing during the study period. Future studies should address the impact of multidisciplinary vascular teams on long-term outcomes.

BACKGROUND The impact and quality of a faculty members publications is a key factor in promotion and tenure decisions and career advancement. Traditional measures, including citation counts and journal impact factor, have notable limitations. Since 2010, alternative metrics have been proposed as another means of assessing the impact and quality of scholarly work. The Altmetric Attention Score is an objective score frequently used to determine the immediate reach of a published work across the web, including news outlets, blogs, social media, and more. Several studies evaluating the correlation between the Altmetric Attention Score and number of citations have found mixed results and may be discipline-specific. OBJECTIVE To determine the correlation between higher Altmetric Attention Scores and citation count for journal articles published in major pharmacy journals. METHODS This cross-sectional study evaluated articles from major pharmacy journals ranked in the top 10% according to the Altmetric Attention Score. Sources of attention that determined the Altmetric Attention Score were obtained, as well each articles open access status, article type, study design, and topic. Correlation between journal characteristics, including the Altmetric Attention Score and number of citations, was assessed using the Spearman’s correlation test. A Kruskal-Wallis 1-way analysis of variance (ANOVA) was used to compare the Altmetric Attention Scores between journals. RESULTS Six major pharmacy journals were identified. A total of 1,376 articles were published in 2017 and 137 of these represented the top 10% with the highest Altmetric Attention Scores. The median Altmetric Attention Score was 19 (IQR 15-28). Twitter and Mendeley were the most common sources of attention. Over half (56.2%) of the articles were original investigations and 49.8% were either cross-sectional, qualitative, or cohort studies. No significant correlation was found between the Altmetric Attention Score and citation count (rs=0.07, P = 0.485). Mendeley was the only attention source that correlated with the number of citations (rs=0.486, P<0.001). The median Altmetric Attention Score varied widely between each journal (P<0.001). CONCLUSIONS The overall median Altmetric Attention score of 19 suggests articles published in major pharmacy journals are near the top 5% of all scientific output. However, we found no correlation between the Altmetric Attention Score and number of citations for articles published in major pharmacy journals in the year 2017.

Background. Diarrheal diseases are still one of the major causes of morbidity in under-five children in sub-Saharan Africa. In Ethiopia, diarrhea is responsible for 9% of all deaths and is the major cause of under-five mortality. Objective. To assess the impact of community-led total sanitation and hygiene on the prevalence of diarrheal disease and factors associated among under-five children in Gamo Gofa Zone. Methods. Community-based comparative cross-sectional study design was used to compare the impact of community-led total sanitation and hygiene intervention on under-five diarrheal disease. Multistage sampling method was employed. The data were collected by using pretested structured questionnaires. Data quality was ensured by daily supervision completeness and consistency. The data were coded, entered, and cleaned by using Epi Info version 7 and were analyzed by using SPSS version 20. Bivariate and multivariable analyses were carried out by using binary logistic regression. Significance was declared by using p value of <0.05 and AOR with 95% confidence intervals. Results. The response rate of this study was 93.3%. The overall diarrhea prevalence was 27.5% (CI = (24.06, 30.97)) which was 18.9% (CI = (14.94, 23.2)) in implemented and 36.2%. (CI = (30.41, 41.59)) in nonimplemented woredas. Children whose age was between 12 and 23 months (AOR = 1.6) and greater than 24 months (AOR = 5), availability of handwashing facilities (AOR = 4), disposal of waste in open field (AOR = 9.7), unimproved source of drinking water (AOR = 6.5), using only water for handwashing (AOR = 6), children who started complementary feeding less than 6 months (AOR = 5.6) and greater than 6 months (AOR = 5.2), and utensils used to feed children such as bottle (AOR = 3.9) were the factors positively associated with diarrhea. Conclusion. The overall prevalence of under-five diarrhea was 27.5%. The prevalence was low in CLTSH woredas as compared with non-CLTSH woredas. The study showed that handwashing facility, using only water for handwashing, open refuse disposal, and unimproved source of drinking water among under-five had a statistically significant association with diarrhea occurrence in CLTSH nonimplemented areas. Integrated efforts are needed from the Ministry of Health together with the WASH Project in improving drinking water, handwashing facilities, and solid waste disposal practices.

Some of the frequently used buzz words in the corporate sector include green leadership, green human resource management, green employee engagement and green work-life balance. The intention of this article is to identify and examine the logical reasons that govern “green work-life balance” or, in simple terms, “greenwashing” work-life balance. The paper also aims at providing a comprehensive conceptualization of work-life balance, while thoroughly examining the components of measuring the construct. Based on a cross-sectional study in the banking industry with a sample of 170 managerial employees, this study analyzes the impact of work-life balance on employee job performance mediated by employee engagement. Results support the assumed relationship between work-life balance and employee job performance embedded in employee engagement. The theoretical contribution of this study concerns the application of role behavior theory to describe the mechanisms shaping the relationship between work-life balance and job performance through employee engagement. The practical implications of the paper include recommendations for improving job performance by enhancing the work-life balance and strengthening employee engagement.
