The impact of education level and socioeconomic status on the association between depressive symptoms and memory in an older population in Latin America: An exploratory analysis from the Brazilian Longitudinal Study of Aging (ELSI-BRAZIL).

Purpose: The globally increasing older population raises concerns about age-related conditions, including cognitive impairment and depressive symptoms. In Latin America, nearly one-third of the population is affected by either of these conditions. However, data investigating the association between cognitive impairment and depressive symptoms, particularly in Brazil, are limited to small-scale studies that have not carefully examined the critical effects of variables such as education level and socioeconomic status on this relationship.

Malignancy diseases and kidneys: A nephrologist prospect and updated review.

Acute kidney injury (AKI), chronic renal failure, and tubular abnormalities represent the kidney disease spectrum of malignancy. Prompt diagnosis and treatment may prevent or reverse these complications. The pathogenesis of AKI in cancer is multifactorial.

Clinical, Radiological, and Outcome Characteristics of Acute Pulmonary Embolism: A 5-year Experience from an Academic Tertiary Center.

Background: Acute pulmonary embolism (PE) is a common and potentially life-threatening condition. This comprehensive study from a Gulf Cooperation Council (GCC) country aimed to evaluate the clinical, radiological, and outcome characteristics associated with acute PE.

Methods: This retrospective observational study analyzed data of patients with confirmed acute PE who were admitted to the largest academic tertiary center in the State of Qatar from January 1, 2014, to December 31, 2018.

Demographics and clinical characteristics of alcohol-related admissions in a tertiary care hospital in Qatar: Does age matter?

Background: Alcohol consumption is a major cause of acute and chronic health conditions associated with comorbidities and traumatic injuries, despite its partial prohibition in some countries. Moreover, alcohol-related hospital admissions increase the burden on the healthcare system. More than 80% of the population in Qatar comprises expatriates.

An unusual etiology of bilateral pulmonary nodules: Another challenge of hide and seek.

An elderly gentleman presented with bilateral pulmonary nodules found incidentally during the workup of acute pancreatitis. He did not have any respiratory or urogenital symptoms. A biopsy of the lung nodule revealed myxoid mesenchymal neoplasm of extraosseous origin.

Extrapulmonary Tuberculosis masquerading as chest wall malignancy: Just never ceases to surprise!

With the emergence of the acquired immunodeficiency syndrome, we witnessed a higher incidence of disseminated and extrapulmonary tuberculosis. The infection sites commonly include lymph nodes, pleura, and osteoarticular areas, although any organ can be involved. Given the atypical presentation of the extrapulmonary disease, it poses a significant diagnostic challenge for the physicians; therefore, a high index of suspicion should be maintained, particularly where tuberculosis is endemic.

Psychological and Coping Strategies Related to Home Isolation and Social Distancing in Children and Adolescents During the COVID-19 Pandemic: Cross-sectional Study.

Background: In December 2019, a novel coronavirus called SARS-CoV-2 was identified as the cause of a cluster of pneumonia cases in Wuhan, China. It rapidly spread due to human-to-human transmission, resulting in a global pandemic. Nearly every country, including Qatar, has established guidelines and regulations to limit the spread of the virus and to preserve public health.

Estimating point prevalence of COVID-19 in Qatar's primary care registered population: an RT-PCR drive-through study protocol.

Background: The first COVID-19 cases in Qatar were reported on 29 February 2020. As the epidemic progresses, essential epidemiological information is needed to facilitate monitoring of COVID-19 in the population and plan the pandemic response in Qatar.

Aim: The primary aim of this cross-sectional study is to estimate the point prevalence of COVID-19 in Qatar's primary care registered population.

Role of Fiberoptic Bronchoscopy in the Rapid Diagnosis of Sputum Smear-negative Disseminated Tuberculosis with Pulmonary Miliary Infiltrates.

Objectives: We sought to evaluate the role of bronchoscopy-related procedures such as bronchoalveolar lavage (BAL), bronchial wash (BW), bronchial brush (B brush), transbronchial biopsy (TBB), and post-bronchoscopy sputum (PBS), alone or in combination, in the rapid diagnosis of negative sputum smear disseminated tuberculosis (TB).

Methods: We performed a secondary post hoc analysis of data collected from our previous study entitled "Disseminated tuberculosis among adult patients admitted to Hamad General Hospital, Qatar: A five-year hospital-based study" with a modified objective.

Results: We identified 27 patients.

Long-term compliance with continuous positive airway pressure in Saudi patients with obstructive sleep apnea. A prospective cohort study.

Objectives: To evaluate continuous positive airway pressure (CPAP) compliance and define predictors of CPAP compliance among Saudi patients with obstructive sleep apnea (OSA) after applying an educational program. 

Methods: This prospective cohort study included consecutive patients diagnosed to have OSA based on polysomnography between January 2012 and January 2014 in King Saud University, Riyadh, Kingdom of Saudi Arabia. All patients had educational sessions on OSA and CPAP therapy before sleep study, and formal hands-on training on CPAP machines on day one, day 7, and day 14 after diagnosis.
