COVID-19 Vaccination Rates and Predictors of Uptake Among Adults With Coronary Heart Disease: Insight From the 2022 National Health Interview Survey.

INTRODUCTION: COVID-19 has become a burden to all nations across the globe, and vaccination currently remains the most effective means of fighting the SARS-COV-2 pandemic. From the time of approval and subsequent distribution of the various COVID-19 vaccines, nearly 72.3% (5.5 billion) of the globe's population have been vaccinated, leaving slightly more than a quarter of the globe's population at risk. With the approval and availability of booster vaccine dosages to individuals with chronic conditions, including coronary heart disease (CHD), it is vital to comprehend the factors underlying the uptake of COVID-19 vaccination in such subgroups. Further, the American Heart Association recommends vaccination against COVID-19 in populations with coronary heart disease (CHD). This is because they are more likely to experience severe outcomes due to COVID-19 infection. This study assesses the uptake of COVID-19 vaccines as well as predictors of its uptake. METHODS: Using the 2022 survey data from the National Health Interview Survey (NHIS), 1,708 adults ≥ 40 years with CHD who responded yes/no to whether they had received the vaccine were identified. A Pearson's chi-square test was used to ascertain differences among those who had received the vaccine and those who had not. A logistic regression (multivariate regression) was used to evaluate predictors of COVID-19 vaccination. RESULTS: About 1,491/1,708 (86.8%) adults ≥ 40 years reported being vaccinated against COVID-19. Among them, 1,065/1,491 (68.4%) had received more than two vaccination doses. The predictors of COVID-19 vaccination were older age (odds ratio (OR): 2.01 (95% confidence interval (CI): 1.40-2.89), p < 0.001), ratio of family income to poverty threshold of 1 and above (OR: 2.40 (95% CI: 1.58-3.64), p < 0.001), having a college degree (OR: 3.09 (95% CI: 1.85-5.14), p < 0.001), and being insured (OR: 3.26 (95% CI: 1.03-10.26), p = 0.044). CONCLUSION: The findings of the study have indicated that 68.4% of adults 40 years and above with CHD have been vaccinated against COVID-19 and have received more than two doses of vaccines. More than half have followed recommendations and have received booster doses of the vaccine. Old age (above 40 years) and a higher socioeconomic class are associated with being more likely to follow COVID-19 vaccination guidelines. Despite the higher vaccination rate of 68.4% in the adults with heart diseases group, strategies for improving booster vaccine awareness alongside accessibility are needed to enhance additional dosage uptake, protect them against novel COVID-19 variants, and ensure the development of sustained immunity.

A Comprehensive Review of Myocardial Bridging: Exploring Diagnostic and Treatment Modalities.

Myocardial bridging (MB) is a congenital coronary artery anomaly involving an overlying myocardium's partial or complete encasement of a coronary artery segment. The obstruction can lead to significant cardiac symptoms, resulting in myocardial ischemia, arrhythmia, and sudden cardiac death. Several approaches, including invasive and non-invasive methods, have been proposed to diagnose and manage MB. Invasive modalities, such as intravascular ultrasound (IVUS) and coronary angiography, offer high specificity and sensitivity. In contrast, non-invasive methods like Doppler ultrasound, multislice computed tomography (MSCT), and magnetic resonance imaging (MRI) are advantageous due to their non-invasive nature, high sensitivity and specificity, and cost-effectiveness. Treatment options for MB mainly focus on relieving symptoms and preventing adverse outcomes. The use of pharmacological agents and surgical and percutaneous interventions has been documented in numerous studies. Studies conclude that MB is a treatable cardiac anomaly, and a combined approach of diagnosis, treatment, and follow-up is necessary to reduce the morbidity and mortality associated with this condition.

The Use of Cannabis and Its Effects on Postpartum Depression.

Cannabis use and depression management have been studied, with a preponderance of exacerbating effects, but there are few studies on postpartum depression (PPD). Depression affects a significant number of women, with a portion of it manifesting as PPD in childbearing women in the United States each year. The pharmacologic management approaches have disadvantages such as side effects, cost-benefit ratio, contraindications, use reluctance, medication adherence, and stigmatization in patients. Anecdotal claims of medical cannabis' therapeutic benefits have led to widespread legalization in several regions, making cannabis and its extracts a possible alternative. Cannabis is widely used during pregnancy and in general. Even though substance use disorders exacerbating depression symptoms have been reported, there are increasing reports and evidence about the therapeutic benefit of dose-dependent cannabis or its extracts in some depression symptoms, such as acute psychosocial stress relief, its purported anxiolytic effect, appetite, and sleep quality, thus stimulating more interest that may be inferred to depression. PPD marijuana use is unclear. This paper reviewed works of literature that claimed cannabis' therapeutic benefit in treating depression and, by extension, PPD. Our findings show the link between cannabis and PPD has not been fully explored. Self-reported studies link marijuana uses to positive mood, anxiety relief, sleep regulation, nausea and vomiting reduction, and appetite stimulation-all PPD symptoms. Others opposed postpartum marijuana use.

Antibiogram at a Rural Hospital Against the Background of COVID-19: A Five-Year Retrospective Review.

Background and objective The role of the antibiogram in reducing hospital length of stay (LOS), mortality rate, health care costs, and, by extension, patients' social, physical, and emotional wellness has a significant impact on the medical community. Hospitals in large cities serve a dynamic population of diverse ethnic groups. Many scholarly works and publications have shown that the antimicrobial pattern in rural settings has significant variability annually. Over the last two years, the spread of coronavirus disease 2019 (COVID-19) has brought about many unknowns in the sphere of healthcare. The pattern of pathology accompanying COVID-19 has affected hospital policies and direct patient management, leading to a paradigm shift in approaches, policies, and resource utilization. The years 2019 to 2021 were marked by many admissions due to COVID-19, and the effects of COVID-19 are still being studied. In light of this, this study examined the changes in sensitivity patterns, new trends, and nature of bacteria isolates, antimicrobial rates, and susceptibility based on a rural hospital's annual antibiogram pertaining to its central departments: the intensive care unit (ICU), patient care unit (PCU), the outpatient unit, and emergency department (ED). Methods This five-year retrospective antibiogram review compared antibiogram patterns two years before the first case of COVID-19 was reported in the hospital and those two years after the initial outbreak. Results The organism comparative susceptibility tests for Escherichia coli (E. coli) were not significant except for increased susceptibility toward nitrofurantoin (p=0.003); Klebsiella pneumoniae (K. pneumoniae) was also not significant except for the increased susceptibility to ciprofloxacin (p=0.003). Pseudomonas aeruginosa (P. aeruginosa) had no changes in susceptibility patterns, while Proteus mirabilis (P. mirabilis) had increased susceptibility to imipenem (p=0.05), aztreonam (p=0.00), and meropenem (p=0.004), with reduced susceptibility to gentamicin (97.47% vs. 88.24%, p=0.006). There was a whopping decrease in the sensitivity of methicillin-resistant Staphylococcus aureus (MRSA) to clindamycin (75.93% vs. 50.7%, p=0.000), linezolid (99.54% vs. 88.73, p=0.004), trimethoprim/sulfamethoxazole (92.59% vs. 74.65%, p=0.001), and vancomycin (99.54% vs. 88.73%, p=0.004). Staphylococcus aureus (S. aureus) had no significant variation except an increase in susceptibility to nitrofurantoin (p=0.023), and perhaps ironically, Streptococcus pneumoniae (S. pneumoniae) had no significant changes in susceptibility pattern. Conclusion Our data demonstrate that the susceptibility of different drugs against different bacterial pathogens varied. However, some antibiotic drugs were found to have high susceptibility against different isolated organisms, and these drugs include amikacin, levofloxacin, vancomycin, cefotaxime, nitrofurantoin, and ceftriaxone. Some organisms showed a significantly declined antibiotic susceptibility, while others showed a significant improvement. The role of COVID-19 regarding these changes is unknown. COVID-19 may not be the cause of the observed differences. We believe that further research on antibiotic legislation and prescribing trends is required. Other non-significant study findings may be attributed to the limited data available to us.

A Meta-Analysis of Randomized Controlled Trials on the Effectiveness of Exercise Intervention in Preventing Sports Injuries.

Athletes risk injury every day during practice sessions and actual games, with the majority of the affected population being young males. The Centers for Disease Control and Prevention 2011-2014 report on sport and recreation-related injuries in the United States has consistently shown the average annual estimate of the millions of dollars spent on sport and recreation injuries. These injuries translate to a significant financial implication for the athlete, the team, the health system, and the public health. We composed a review protocol. We enumerated our inclusion and exclusion criteria, injury definition, and search strategy. We searched PubMed and SPORTDiscus. Then we used Forrest plots for the meta-analysis of the relevant selected studies. We used various keywords in our search strategy. These included "injury," "sports," "exercise," "prevention," "techniques," and every possible combination of them. Search results showed 2516 hits with our keywords, and we included 20 of those results. Twenty trials, including 19712 individuals with 2855 injuries, were analyzed. Eccentric Training relative risk (RR) of 0.54 (95% CI 0.395 to 0.739 with X2 of p < 0.05) showed that the risk of the injury was decreased by 54% in the intervention group compared to the control group. In the neuromuscular training group, a RR of 0.682 (95% CI 0.621 to 0.749 with X2 of p < 0.001) showed that the risk of the injury was decreased by 68.2% in its intervention group subgroup compared to its control group. Also, the "11" International Federation of Association Football (FIFA) program had a RR of 0.771, indicating that there was a 77.1% decrease in injury by this set of exercises (95% CI 0.728 to 0.816 with X2 of p < 0.05), and this "11" FIFA program also had the most preventative effects. Warm-up had a RR of 0.843 (95% CI 0.749 to 0.949 with X2 of p < 0.05) and showed small prevention. Strength Training RR of 0.97 (95% CI 0.57 to 1.63 with X2 of p > 0.05) had no preventive effect. Our analysis showed that different exercises have preventive roles in sports injuries. The warm-up FIFA, neuromuscular training, and eccentric training reduced the risk of injury in the intervention group compared to the control group by a high percentage. At the same time, neuromuscular warm-up and FIFA 11 dynamic warm-up also decreased the relative risk of injury in the intervention group. These effects varied among exercise type, injury type, and sport.

Diagnostic utility of PAX8, TTF-1 and napsin A for discriminating metastatic carcinoma from primary adenocarcinoma of the lung.

TTF-1 and napsin A are useful biomarkers for differentiating primary lung adenocarcinoma from metastatic tumors. Studies have shown, however, that TTF-1 and napsin A also can be expressed in extrapulmonary carcinomas, and that a small fraction of primary lung adenocarcinomas do not co-express these two markers. We attempted to determine whether a tissue-specific transcriptional factor, PAX8, can help determine primary sites of lung carcinomas. Immunohistochemical stains for PAX8, TTF-1 and napsin A were performed on 103 cases of metastatic lung carcinomas from a variety of origins and 120 cases of primary lung adenocarcinomas. Our data demonstrated that all 103 metastatic carcinomas were negative for napsin A, while 14 (13.6%; four thyroid, two endometrium, three colon, one prostate, one salivary adenoid cystic, two renal cell carcinomas, and one ovary) showed weak to strong TTF-1 nuclear staining in 5-60% of the tumor cells. All primary lung adenocarcinomas were negative for PAX8, whereas 46 (44.7%) metastatic carcinomas from the kidney (29/33), ovary (6/8), endometrium (5/5), endocervix (1/1), thyroid (4/5) and urinary tract (1/3) were positive for PAX8. Our data demonstrate that of combined use of PAX8, TTF-1 and napsin A is reliable to separate reliably lung primary from metastatic tumors.

Taurine: a novel tumor marker for enhanced detection of breast cancer among female patients.

INTRODUCTION: The antioxidant Taurine found to display antineoplastic effect through down regulation of angiogenesis and enhancement of tumor cell apoptosis. It has been found that progressive inhibition of apoptosis and induction of angiogenesis may contribute to tumor initiation, growth and metastasis in the pathogenesis of breast cancer. AIM OF THE STUDY: To correlate taurine level with the levels of some bioomolecules operating in both angiogenesis (VEGF, CD31) and apoptosis (TNF-α and Caspas-3) which could help for breast cancer pronostication and to evaluate a possible role of serum taurine level as an early marker for breast cancer in Egyptian patients. PATIENTS AND METHODS: Four groups of a total 85 female candidates were studied in this work. The first group consists of 50 female patients at National Cancer Institute (NCI), Cairo University were diagnosed and undergoing surgery for breast carcinoma. In the second group 10 having benign breast lesions, were included. The third group consists of five cases, with positive family history. Twenty healthy females were also recruited as control. A preoperative blood sample were taken from each patient to measure serum level of VEGF; Taurine; CA15.3 and TNF- α. Sample of fresh tumor and their corresponding safety margins were obtained from the first and second groups, for determination of caspase-3; histopathological examination and immunohistochemical assay of VEGF and CD31. RESULT: No significant differences in the serum level of CA15.3 between the breast cancer patients, the high risk and the control group. TNF-α (apoptotic biomolecule) level showed a significant difference only between breast cancer group and control group. The VEGF (angiogenic biomarker) showed a highly significant difference between breast cancer patients, the high risk and the control group. Regarding the antioxidant taurine (antiangiogenic biomolecule) serum level in breast cancer group exhibited a value strongly lower than the high risk and control group. Also the correlative ratio between the angiogenic/apoptotic biomarker (VEGF/TNF-α) showed a highly significant difference between the main previous three groups. Same observation were also noticed in the correlation between angiogenic/antiangiogenic (VEGF/taurine) ratio in the same groups. Moreover the enzymatic activities of Casp-3 in the tissue homogenate were statistically higher in adjacent normal tissues than in malignant tissues. The result of immunohistochemical investigation showed a significant increase in the density of intracellular VEGF and microvessel density expressed as CD31 in cancer cases compared to normal adjacent tissue. CONCLUSION: It is suggested that assessment of taurine level in sera of patients with high risk for breast cancer are of great value in the early diagnosis of malignant changes in the breast.

Effect of variety and moisture content on some engineering properties of paddy rice.

The effect of variety and moisture content on some engineering properties of five improved paddy rice varieties was investigated within moisture content range of 10% and 30% dry basis (d.b.). Increase in moisture content was found to increase the linear dimensions, mass of 100 seeds, surface area, apparent volume, true volume, arithmetic mean diameter, effective geometric diameter, sphericity, angle of repose, porosity and static coefficient of friction while bulk density and true density decreased with increase in moisture content. Static coefficient of friction was found to increase as moisture content increased from 0.34-0.46, 0.35-0.59, 0.36-0.46 and 0.34-0.45, respectively on plywood, galvanized steel, mild steel and glass structural surfaces. The highest static coefficient was found on galvanized steel. Angle of repose was found to increase as moisture content increases. The study concludes that variety and changes in moisture content significantly (P < 0.05) affected most of the engineering properties determined.

Immunohistochemistry in the evaluation of neovascularization in tumor xenografts.

Angiogenesis, or neovascularization, is known to play an important role in the neoplastic progression leading to metastasis. CD31 or Factor VIII-related antigen (F VIII RAg) immunohistochemistry is widely used in experimental studies for quantifying tumor neovascularization in immunocompromised animal models implanted with transformed human cell lines. Quantification, however, can be affected by variations in the methodology used to measure vascularization including antibody selection, antigen retrieval (AR) pretreatment, and evaluation techniques. To examine this further, we investigated the microvessel density (MVD) and the intensity of microvascular staining among five different human tumor xenografts and a mouse syngeneic tumor using anti-CD31 and F VIII RAg immunohistochemical staining. Different AR methods also were evaluated. Maximal retrieval of CD31 was achieved using 0.5 M Tris (pH 10) buffer, while maximum retrieval of F VIII RAg was achieved using 0.05% pepsin treatment of tissue sections. For each optimized retrieval condition, anti-CD31 highlighted small vessels better than F VIII RAg. Furthermore, the MVD of CD31 was significantly greater than that of F VIII RAg decorated vessels (p<0.001). The choice of antibody and AR method has a significant affect on immunohistochemical findings when studying angiogenesis. One also must use caution when comparing studies in the literature that use different techniques and reagents.

Vaginal masses: magnetic resonance imaging features with pathologic correlation.

The detection of vaginal lesions has increased with the expanding use of cross-sectional imaging. Magnetic resonance imaging (MRI) - with its high-contrast resolution and multiplanar capabilities - is often useful for characterizing vaginal masses. Vaginal masses can be classified as congenital, inflammatory, cystic (benign), and neoplastic (benign or malignant) in etiology. Recognition of the typical MR imaging features of such lesions is important because it often determines the treatment approach and may obviate surgery. Finally, vaginal MR imaging can be used to evaluate post-treatment changes related to previous surgery and radiation therapy. In this article, we will review pertinent vaginal anatomy, vaginal and pelvic MRI technique, and the MRI features of a variety of vaginal lesions with pathological correlation.

Laparoscopic cholecystectomy in the Academy Medical Centre, Khartoum, Sudan.

OBJECTIVE: To highlight the results of minimum access surgery in Sudanese patients. DESIGN: Prospective audit of laparoscopic cholecystectomies. SETTING: The Academy Medical center (Yastabshiroon), Teaching University Hospital. SUBJECTS: All the patients who had this type of surgery were included in the study. Clinical and operative data were evacuated from March 2002 to March 2004. MAIN OUTCOME MEASURES: One hundred and twenty patients had laparoscopic cholecystectomy at the center. There were 97 females and 23 males; age range was 22-90 years with a mean of 52 years. Indications for surgery were repeated attacks of biliary colic in 38, chronic cholecystitis in 60, acute cholecystis in 10 and mucocele in 12 patients. RESULTS: Three patients with chronic cholecystitis had peri-portal fibrosis due to bilharzial infestations, in spite of which laparoscopic surgery was successful. Operating time was 25-120 minutes with a mean of 47 minutes. Conversion was performed in six (2%) patients because of bleeding and four for extensive dense adhesions. There was one mortality case of a 75-year-old female who had pulmonary embolus. Hospital stay was 16-24 hours with a mean of 22 hours. Two patients had port site discharge. CONCLUSION: In general, patients were satisfied with the results of surgery and this encourages us to popularise this procedure to take off in the Sudan.

The possible role of the age of the human host in determining the localization of hydatid cysts.

Cystic hydatid disease or cystic echinococcosis (CE) is a cyclozoonotic infection distributed world-wide. The morbidity attributable to the infection depends on the size of the cyst(s) and the organ(s) involved. The cysts are most commonly found in the liver and lungs but certain locations have been reported to be more prevalent in children and/or young adults than in older subjects. In order to identify the relationship, if any, between the age of the patient and the site of involvement, the age and cyst distribution of 92 cases of CE were analysed. Lung, brain, spinal and orbital hydatid cysts were more commonly seen in younger patients whereas other sites were preferentially involved in older patients. The factors that determine the final localization of the cysts are discussed. It is concluded that age somehow alters the host-parasite relationship and thus affects the organ distribution of the cysts.
