Predictors of mortality among hospitalized hypertensive patients with COVID-19 during third and fourth waves in Pakistan.

INTRODUCTION: Hypertension significantly contributes to the severity and mortality of COVID-19 patients. It has also been a risk factor for prolonged hospitalization and the need for intensive care. However, the data is still evolving. Therefore, this study investigated the predictors of mortality among hypertensive COVID-19 patients. METHODOLOGY: A single-center cohort study was performed at Indus Hospital and Health Network, Karachi, Pakistan, between April 1, 2021, and October 31, 2021. This study included 333 hospitalized hypertensive COVID-19 patients and evaluated their clinical characteristics and survival outcomes. A multivariate logistic regression model was applied in IBM SPSS 27.0 to determine the predictors of mortality. RESULTS: The majority of patients were females (54.7%), the median age was 62 [55-70] years, with co-existing diabetes (56.5%) and severely ill (52.6%). The independent predictors of mortality identified were age ≥ 65 years (aOR 20.89, 95% CI, 5.81-75.15; p < 0.001), pulse rate (aOR 1.03, 95% CI 1.01-1.63; p = 0.006), serum creatinine (aOR 1.34, 95% CI 1.11-1.63; p = 0.002), use of antibiotics (aOR 3.40, 95% CI 1.29-8.98; p = 0.014)), corticosteroid (aOR 49.68, 95% CI 1.83-1350.31; p = 0.020), and who needed high flow oxygen supply (aOR 13.08, 95% CI 1.70-100.54; p < 0.001), non-invasive mechanical ventilation (aOR 229.01, 95% CI 29.30-1789.71; p < 0.001) and invasive mechanical ventilation (aOR 379.54, 95% CI 36.60-3935.87; p < 0.001). CONCLUSIONS: Our study suggests that older age, elevated pulse rate, serum creatinine, use of antibiotics and corticosteroids, and the need for mechanical ventilation predict mortality among hypertensive COVID-19.

Thyroid and Its Ripple Effect: Impact on Cardiac Structure, Function, and Outcomes.

Thyroid dysfunction is a widespread and complex issue in the field of endocrine disorders. It has a significant impact on multiple physiological systems, particularly on the heart. This review explores the complex interaction between thyroid dysfunction and cardiac dynamics, examining the detailed network of molecular, cellular, and systemic changes that underlie the close connection between these two physiological areas. Thyroid dysfunction, which includes both hyperthyroidism and hypothyroidism, is a common endocrine condition that affects millions of people worldwide. The thyroid hormones thyroxine and triiodothyronine regulate various metabolic activities essential for maintaining cellular balance. Disruptions in thyroid function result in widespread consequences, affecting the cardiovascular system. Thyroid hormones directly impact cardiac muscle cells, controlling their ability to contract, their electrical properties, and their reaction to hypertrophy. Thyroid dysfunction goes beyond the level of individual cells and involves complex interactions among vascular dynamics, neurohormonal control, and endothelial function. These factors all contribute to the development of cardiovascular illness. The impact of thyroid dysfunction on cardiac structure, function, and outcomes is not limited to a one-way pattern. Instead, it involves a dynamic two-way interaction. The manifestations of this condition can vary from minor changes in the electrical activity of the heart to more obvious structural abnormalities, such as an increase in the size of the heart muscle and a decrease in its ability to relax during the filling phase. Furthermore, the correlation between thyroid dysfunction and adverse cardiovascular outcomes, such as heart failure and arrhythmias, highlights the clinical importance of this connection. This review provides a complete overview of the relationship between thyroid dysfunction and cardiac dynamics by analyzing a wide range of research from clinical, molecular, and epidemiological perspectives. This study seeks to enhance our comprehension of the comprehensive effects of thyroid dysfunction on the anatomy and function of the heart by explaining the complex molecular mechanisms and systemic consequences. The goal is to establish a basis for informed clinical treatment and future research efforts.

Exploring Patient Safety Culture: A Study of Community Pharmacies in Karachi, Pakistan.

Background Community pharmacies are integral to the healthcare system, actively contributing to patient safety through accurate dispensing, education, collaboration, monitoring, and the implementation of safety protocols. Their accessibility and role as medication experts make them key partners in promoting positive health outcomes for individuals and communities. Objective The current study will evaluate the patient safety culture (PSC) among community pharmacies in Karachi, Pakistan. Additionally, this study will measure the association between patient safety culture in community pharmacies and the demographic characteristics of the pharmacy staff. Methods A cross-sectional survey of pharmacy staff was conducted using a survey instrument developed by the US Agency for Healthcare Research and Quality (AHRQ). Demographic variables and assessments of safety culture in pharmacies were studied. The data were analyzed using descriptive statistics. Results Among the 102 participants, positive responses ranged from 30% to 87.5%. The highest positive response was for the dimension "mistakes in communication" (86.3%), followed by "communication across shifts" (82.2%) and "communication openness" (81.7%). The dimensions "overall perceptions of patient safety" and "response to mistakes" had the lowest positive responses (56.0% and 60.9%, respectively). Furthermore, many staff did not regularly record the errors, even if they impacted the practices. Conclusion There was an overall unfavorable perception of patient safety culture among the surveyed pharmacies of Karachi, Pakistan. However, the communication dimensions showed the highest positive response. There is a strong need to improve the overall perception of patient safety among the staff and develop an optimistic response to mistakes.

Thrombolysis vs Anticoagulation: Unveiling the Trade-Offs in Massive Pulmonary Embolism.

Massive pulmonary embolism (MPE) is a severe form of venous thromboembolism (VTE) wherein enormous blood clots block the pulmonary arteries, resulting in substantial illness and death. Even with the progress made in diagnostic methods and treatments, the most effective approach for managing MPE is still a topic of considerable discussion. This study examines the delicate equilibrium between thrombolysis and anticoagulation in managing the problematic clinical situation posed by MPE, elucidating the compromises linked to each strategy. The genesis of MPE lies in the pathophysiology of VTE, when blood clots that originate from deep veins in the lower legs or pelvis move to the pulmonary vasculature, leading to an abrupt blockage. This obstruction leads to a series of hemodynamic alterations, such as elevated pulmonary vascular resistance, strain on the right ventricle, and compromised cardiac output, finally resulting in cardiovascular collapse. The seriousness of MPE is commonly categorized according to hemodynamic stability, with significant cases presenting immediate risks to patient survival. Traditionally, heparin has been the primary approach to managing MPE to prevent the spread of blood clots and their movement to other parts of the body. Nevertheless, there have been ongoing discussions regarding the effectiveness of thrombolysis, which entails the immediate delivery of fibrinolytic drugs to remove the blood clot. The use of thrombolysis in managing MPE is being reconsidered because of concerns over bleeding complications and long-term results despite its capacity to resolve the blocking clot quickly. This review rigorously analyzes the current body of evidence, exploring the intricacies of thrombolysis and anticoagulation in MPE. The focus is on evaluating the risk-benefit balance of each treatment option, considering aspects such as the patient's other medical conditions, hemodynamic stability, and potential long-term consequences. This review aims to clarify the complexities of the thrombolysis versus anticoagulation dilemma. It seeks to provide clinicians, researchers, and policymakers with a thorough understanding of the trade-offs in managing MPE. The goal is to facilitate informed decision-making and enhance patient outcomes.

Survey data of public in Sindh Pakistan regarding willingness to accept COVID-19 vaccination.

OBJECTIVE: The COVID-19 pandemic has badly affected the world with its devastating effects, including Sindh, Pakistan. A massive vaccination campaign against COVID-19 is considered one of the effective ways to curtail the spread of the disease. However, the acceptability of the COVID-19 vaccine is based on the general population's knowledge, attitude, perception and willingness for vaccination. Therefore, a survey among the public in Sindh, Pakistan, was done to evaluate their knowledge, attitude, perception and willingness to accept COVID-19 vaccination. METHOD: The online survey was conducted among the residents of Sindh, Pakistan, in July 2021 through a survey tool designed using Google Forms and sent to the population through various social media. RESULTS: Of 926 study participants, 59.0% were male, and 68.6% were aged between 18 and 31 years. Higher percentages of responses were recorded from the Hyderabad division (37.5%), and 60.0% of respondents were graduates, with 34.8% of them in the private sector. The results showed that 36.4% of respondents had good knowledge, and 30.3% had a positive attitude toward COVID-19 vaccination. Almost 77% of respondents perceived that everyone should get vaccinated in the country and those health care workers on priority. A majority (80.8%) of respondents were willing to accept COVID-19 vaccination. CONCLUSION: Despite having insufficient knowledge and a low percentage of positive attitude public in Sindh are willing to be vaccinated. Based on this finding, more effort has to be done to promote vaccination among the public, especially among the less educated population.

Knowledge, perception, and fear among the global population towards newly evoked variant Omicron (B.1.1.529).

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-1), notoriously known as COVID-19, emerged in 2019 and was responsible for causing acute respiratory collapse. Moreover, in September 2020, new variant cases of severe acute respiratory syndrome coronavirus 2 were reported in the United Kingdom, with many patients and deaths. This study aimed to see knowledge, perception, and fear among the global population towards a new variant of severe acute respiratory syndrome coronavirus 2, known as Omicron (B.1.1.529). This online cross-sectional global study was conducted during the emergence of the B.1.1.529 variant, also known as the Omicron variant. The survey was carried out from 2nd December 2021 to 3rd January 2022. The descriptive analysis was presented as frequencies (N), percentages (%), and mean ± standard deviation (m ± SD). The association between dependent and categorical independent variables was determined using the Chi-square test (x2). Statistical analysis was performed by using SPSS version 23. Of 353 respondents, approximately 61% were females. One hundred fifty-four respondents were in the age group of 18-27 years. The average age was 31.53±10.3 (mean± SD). The majority of respondents (43.9%) were from Indonesia. The mean knowledge score about the Omicron variant was 3.18±1.14. Our study suggests that people have some knowledge about the new variant, Omicron (B.1.1.529). Besides, there was a significant association (p = 0.05) for the perception of the fatality rate of Omicron among the respondents from different countries. However, there is still an ample research gap in enlightening people about this infection (B.1.1.529).

A total of 946 respondents participated in the study, of which the majority were female (514, 54.3%). Most students belonged to a medical background, specifically pharmaceutical sciences. Most of the respondents did not know about monkeypox before 2022 (646, 68.3%). Regarding overall knowledge of monkeypox, most of the respondents had average knowledge (726, 76.7%), with very few having good knowledge (60, 6.3%). Regarding overall attitudes towards monkeypox, most of the respondents had neutral attitudes (648, 68.5%). There was a significant association between knowledge of Monkeypox with the type of academic degree (p < 0.001), type of discipline (p < 0.001), and region of respondents (p < 0.001). The willingness to vaccinate among the population was (67.7%). The current study pointed out that the overall knowledge of monkeypox was average in most respondents, with considerable knowledge gaps in most aspects. The overall attitude towards monkeypox was neutral. Further, the knowledge about monkeypox was strongly associated with academic degree, study discipline, and region of respondents. Our findings emphasize the need to raise public awareness by educating students on the monkeypox virus. This will improve adherence to preventative recommendations.

Bullous Pyoderma Gangrenosum Associated with Hairy Cell Leukemia and Its Complete Response to Cladribine Therapy.

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis seen in association with systemic disorders including hematologic malignancies. Hairy cell leukemia (HCL) however, is an unusual association of PG. We describe a 49-year old lady who presented to our hematology clinic with easy fatiguability and ulcerative skin lesions of 6 months duration. Examination revealed pallor and massive splenomegaly. Indurated, ulcerated lesion with undermined edges and necrotic base was observed on left thigh. Investigations revealed pancytopenia and bone marrow examination identified typical hairy cells. Flow cytometry of marrow aspirate was suggestive of classical HCL. BRAF V600E mutation was detected in peripheral blood by reverse transcriptase polymerase chain reaction. Skin biopsy revealed neutrophilic dermatosis and findings classical of bullous PG. Cladribine therapy (0.09 mg/kg/day by continuous intravenous infusion for 7 days) led to remission of both HCL and PG after a duration of 4 weeks. Cladribine monotherapy in a case of PG with HCL may avoid the additional immunosuppresion risk imposed by treating PG separately with corticosteroids. Immunosuppressive role of cladribine might be helpful in treating PG concurrent with HCL.

Unsuspected invasive neonatal gastrointestinal mucormycosis: A clinicopathological study of six cases from a tertiary care hospital.

AIM: To analyse the clinicopathological features of neonatal mucormycosis MATERIALS AND METHODS: Retrospective analysis of cases of neonatal gastrointestinal mucormycosis. RESULTS: THERE WERE SIX NEONATES WITH MALE: female ratio of 1:1. Except one all were preterm babies. The clinical presentation was abdominal distension in the majority. All were clinically diagnosed as either NEC or toxic megacolon with perforation. Neonatal gastrointestinal mucormycosis was not suspected clinically in any. All the children were explored immediately. Biopsy revealed transmural hemorrhagic necrosis/infarction of the intestinal wall with fungal hyphae. CONCLUSIONS: The physicians should have a high index of suspicion for gastrointestinal tract mucormycosis in neonates with metabolic disturbances who present with abdominal distension and pneumoperitoneum. Early diagnosis and aggressive medical and surgical treatment may improve the outcome of neonates with this potentially lethal invasive disease.

Evidence for tissue selectivity of the synthetic androgen 7 alpha-methyl-19-nortestosterone in hypogonadal men.

The potent synthetic androgen 7 alpha-methyl-19-nortestosterone (MENT) is resistant to 5 alpha-reductase but is a substrate for aromatase. It may therefore offer selective sparing of the prostate gland while supporting other androgen-dependent tissues. MENT acetate implants were administered for 24 wk to 16 hypogonadal men, randomly allocated to 1 or 2 implants (groups I and II, respectively; releasing approximately 400 microg/d x implant). Hemoglobin concentration and hematocrit were maintained during MENT treatment. Prostate volume fell in group I and to a small, but statistically nonsignificant, degree in group II; the level of prostate-specific antigen fell significantly in both. Lumbar spine bone mineral density decreased in both groups. Sexual behavior and erectile function declined in group I, but were maintained in group II. Thus, overall, one MENT implant appeared to provide subphysiological androgen replacement. The 2-implant dose of MENT was able to maintain most androgen-dependent functions, except bone mass, and there was evidence to support selective sparing of the prostate gland. These results demonstrate for the first time in humans the selectivity of MENT in tissues dependent on 5 alpha-reductase. In addition, our data are consistent with the importance of adequate estrogenicity as part of the necessary spectrum of activity of an androgen for replacement therapy in men.
