Epidemiology of extended-spectrum beta-lactamase producing Enterobacteriaceae in Qatar: A 3-year hospital-based study.

Background: The incidence of ESBL infections is exponentially increasing with variable prevalence among geographical areas and treatment settings. Identifying local prevalence rate and patient-related factors will help in earlier recognition and initiation of appropriate antibiotics treatment of patients with ESBL infections.

Methods: Retrospective analysis of all positive cultures for ESBL producing Enterobacteriaceae collected in Al-Khor hospital from January 2010 to December 2012.

Prevalence and global trends of polypharmacy among people living with HIV: a systematic review and meta-analysis.

Background: There has been a rising prevalence of polypharmacy among people living with HIV (PLWH). Uncertainty however remains regarding the exact estimates of polypharmacy among these cohorts of patients.

Methods: We conducted a systematic search of PubMed; EMBASE, CROI, Cochrane Database of Systematic Reviews; Science Citation Index and Database of Abstracts of Reviews of Effects for studies between 1 January 2000 and 30 June 2021 that reported on the prevalence of polypharmacy (ingestion of > 5 non-ART medications) among PLWH on antiretroviral therapy regimen (ART).

HIV and AIDS-defining opportunistic illnesses in the state of Qatar: A cohort population-based retrospective study covering 17 years (2000-2016).

Background And Introduction: Human immune deficiency virus (HIV) infection remains a major health problem since discovery of the virus in 1981. Globally, since introduction of antiretroviral therapy, AIDS-related mortality was reduced by 47% since 2010. Also, HIV-related opportunistic infections (OIs) became less common, especially with use of prophylaxis to prevent such infections.

Accuracy of clinical scoring systems for the diagnosis of tuberculosis meningitis in a case mix of meningitides a retrospective cohort study.

Background: Tuberculosis meningitis (TBM) is elusive to diagnosis. Two widely used clinical scores are the Thwaites diagnostic score (TDS) and The Lancet Consensus score (LCS). We aim to evaluate the accuracy of these scores in a retrospective cohort of meningitis patients.

Diagnostic Delay among Adults with Pulmonary Tuberculosis in a High Gross Domestic Product Per Capita Country: Reasons and Magnitude of the Problem.

Background: To determine the mean and median delays in pulmonary tuberculosis (PTB) diagnosis among adults in one of the world's highest gross domestic product per capita countries and identify patient and health system-related reasons for these delays.

Methods: This is a cross-sectional, face-to-face, prospective study of 100 subjects with confirmed PTB, conducted at main tuberculosis (TB) admitting facilities in Qatar. The mean and median diagnostic delays were measured.

Hepatitis E in Qatar imported by expatriate workers from Nepal: epidemiological characteristics and clinical manifestations.

Prompted by cases of acute hepatitis in expatriate workers presenting at Alkhor Hospital, Qatar, a limited prospective observational study was conducted from July 2005 to June 2006 to determine the epidemiological and clinical features of patients (predominantly Nepalese) presenting with acute hepatitis. Countrywide during that period samples from 86 Nepalese presenting at different centers were found to be anti-HEV IgG positive and 50 of these were also positive for anti-HEV IgM. Fifty-eight of those Nepalese were seen and treated at Alkhor Hospital and of them 43 were confirmed as cases of acute HEV, being positive for both anti-HEV IgM and IgG.

Rupture of spleen in a mechanically ventilated patient with falciparum malaria admitted with pulmonary edema.

Rupture of the spleen in malaria may constitute a diagnostic challenge to many clinicians particularly in non-endemic areas where experience with malaria is limited. Our aim is to increase the awareness among clinicians from non-endemic areas of serious malarial complications. We present a young American military man who was admitted to Hamad General Hospital and had 2 serious malarial complications, namely, acute pulmonary edema and rupture of the spleen.
