Doxycycline's Potential Role in Reducing Thrombosis and Mortality in Critically Ill Patients With COVID-19: A Multicenter Cohort Study.

Doxycycline has revealed potential effects in animal studies to prevent thrombosis and reduce mortality. However, less is known about its antithrombotic role in patients with COVID-19. Our study aimed to evaluate doxycycline's impact on clinical outcomes in critically ill patients with COVID-19.

Patient Beliefs on Antibiotic Prescribing in Primary Care: A Cross-Sectional Survey in Saudi Arabia.

Background Antibiotic overuse is a critical global health issue, and patient attitudes and expectations play a significant role in the inappropriate use of antibiotics. Limited research has been conducted on patient knowledge, attitudes, and perceptions of antibiotic use in Saudi Arabia. This survey aimed to assess patients' knowledge and attitudes related to antibiotic use in Jeddah, Saudi Arabia.

Insights Into Medication Adherence Among Patients With Chronic Diseases in Jeddah, Saudi Arabia: A Cross-Sectional Study.

Background Non-adherence to medication is a common problem in managing chronic diseases, which are a significant public health concern globally. This study aimed to identify factors related to medication adherence among patients with chronic diseases in Saudi Arabia. Methods A cross-sectional survey design was used to collect data through an online survey administered to 400 patients with chronic diseases residing in Jeddah between January and March 2023.

Colistin Loading Dose in Septic Patients with Gram Negative Infections.

Purpose: Intravenous (IV) colistin is commonly used to treat multidrug-resistant gram-negative infections. It is primarily eliminated renally and may induce acute kidney injury (AKI) at a rate of up to 53%. Consequently, septic patients who require colistin administration have an additional risk of developing AKI.

Correlation Between Fine Needle Aspiration Cytology (FNAC) and Permanent Histopathology Results in Salivary Gland Masses.

Objective Fine-needle aspiration cytology (FNAC) has been widely accepted as a diagnostic safe method for preoperative assessment of salivary gland lesions. This diagnostic tool is inexpensive, easy to perform, relatively painless and it provides useful information to differentiate between benign and malignant salivary gland tumors that helps in the management and surgical planning. This study was undertaken to compare FNAC results with permanent histopathological findings of salivary gland tumors in order to assess its diagnostic accuracy.

Peripheral Neuropathy as a Risk Factor for Developing Cardiovascular Disease in Diabetic Patients.

Background Type 2 diabetes mellitus (DM) is prevalent in developing countries and is associated with many comorbidities, including diabetic peripheral neuropathy (DPN) and cardiovascular disease (CVD). In this study, we assessed and evaluated the association between DPN and CVD. Methods The study is a cross-sectional study that included DM patients who are attending DM primary care clinics.

Recurrence Rate in a Patient Treated with Colon Resection Followed by Chemotherapy in Comparison to a Patient Treated with Colon Resection without Chemotherapy.

Given that colon cancer is one of the most prevalent cancers worldwide, it is essential to employ strategies to try to reduce its incidence and recurrence rate. Though colon cancer is a sporadic disease in the vast majority of cases, multiple risk factors are linked to this disease, namely, obesity and cigarette smoking. Additionally, not many studies have been done in Saudi Arabia studying the recurrence rate of colon cancer.

Factors underlying suboptimal diagnostic performance in physicians under time pressure.

Context: Time pressure has been implicated in the suboptimal diagnostic performance of doctors and in increases in diagnostic errors. However, the reasons underlying these effects are not clear. The aim of this study was to investigate the influence of time pressure on physicians' diagnostic accuracy and to explore the mediating effects of perceived stress (emotional pathway) and number of plausible diagnostic hypotheses (cognitive pathway) on the proposed relationship.

Renal failure as a risk factor for venous thromboembolism in critically Ill patients: a cohort study.

Rationale: The relationship between kidney function and venous thromboembolism (VTE) in critically ill patients is not well studied. The main objective of this study was to evaluate this relationship in patients admitted to a medical-surgical intensive care unit (ICU).

Methods: This was a retrospective study of 798 patients admitted to a tertiary-care ICU and prospectively followed for the development of clinically suspected and radiologically diagnosed deep venous thrombosis or pulmonary embolism.

Even mild hyperlactatemia is associated with increased mortality in critically ill patients.

Introduction: The clinical significance of elevation of lactate levels within the reference range is not well studied. The objective of this study was to determine the best cutoff threshold for serum lactate within the reference range (0.01 to 2.

Dialysate potassium and risk of death in chronic hemodialysis patients.

Background: Few data guide the prescription of dialysate potassium (dK) in hemodialysis, which is usually prescribed empirically on the basis of predialysis serum potassium levels.

Methods: This was a retrospective cohort study of prospectively collected data. We studied all patients initiating chronic hemodialysis in the Northern Alberta Renal Program (NARP) between January 2001 and December 2006.
