Dynamics of Anti-S IgG Antibodies Titers after the Second Dose of COVID-19 Vaccines in the Manual and Craft Worker Population of Qatar.

There is limited seroepidemiological evidence on the magnitude and long-term durability of antibody titers of mRNA and non-mRNA vaccines in the Qatari population. This study was conducted to generate evidence on long-term anti-S IgG antibody titers and their dynamics in individuals who have completed a primary COVID-19 vaccination schedule. A total of 300 male participants who received any of the following vaccines BNT162b2/Comirnaty, mRNA-1273, ChAdOx1-S/Covishield, COVID-19 Vaccine Janssen/Johnson, or BBIBP-CorV or Covaxin were enrolled in our study.

Knowledge, awareness, and attitude regarding infection prevention and control among medical students: a call for educational intervention.

Background: Medical students can be exposed to serious health care-associated infections, if they are not following infection prevention and control (IPC) measures. There is limited information regarding the knowledge, awareness, and practices of medical students regarding IPC and the educational approaches used to teach them these practices.

Aim: To evaluate the knowledge, awareness, and attitude of medical students toward IPC guidelines, and the learning approaches to help improve their knowledge.

Epidemiology of bacteraemia in Hamad general hospital, Qatar: a one year hospital-based study.

We conducted a one-year observational study from July 2007 to June 2008 to describe the epidemiology of bacteraemia at Hamad general hospital. During this period, a total of 452 episodes of bacteraemia occurred, which corresponds to a rate of 19/1000 hospital admissions. Most patients 58.

Campylobacter peritonitis complicating continuous ambulatory peritoneal dialysis: report of three cases and review of the literature.

Background: The micro-organisms involved in continuous ambulatory peritoneal dialysis (CAPD) peritonitis are usually gram-positive cocci of cutaneous origin. Campylobacter species are rarely implicated as a cause of CAPD peritonitis.

Methods: A retrospective review of 100 consecutive episodes of peritonitis was carried out in patients undergoing CAPD or automated PD in our hospital from June 2004 to December 2007.

A rare and unsuspected complication of Clostridium difficile infection.

Objective: To report the occurrence of abdominal compartment syndrome (ACS) due to infection with Clostridium difficile.

Design: Case report.

Setting: Trauma intensive care unit (TICU) of Hamad General Hospital, a teaching hospital in Doha, Qatar.

Guillain-Barré syndrome associated with Salmonella paratyphi A.

A 31-year-old Nepali man was admitted to the intensive care unit with a 3-day history of fever associated with four-limb weakness, followed by difficulty in swallowing. The patient came from Nepal 20 days before admission. On examination the patient was conscious and appeared ill, with a temperature of 38.

Irreversible papillitis and ophthalmoparesis as a presenting manifestation of neurobrucellosis.

A 35-year-old man presented with a meningeal syndrome and acute onset of visual blurring. Clinical investigations revealed bacterial meningitis with bilateral papillitis and ophthalmoparesis. Serum and cerebrospinal fluid serology confirmed the diagnosis of chronic active neurobrucellosis.

Acute bacterial meningitis in Qatar.

Objective: To study the changes in the epidemiology, clinical and bacteriological profiles of bacterial meningitis in the era of the Haemophilus influenzae type b (Hib)vaccine and pneumococcus resistance.

Methods: This is a retrospective study of children aged <12 years admitted to the Hamad Medical Corporation, Qatar between January 1998 through December 2002 with positive cerebrospinal fluid culture.

Results: We described 64 patients with culture proven bacterial meningitis.

Antibiotic prescribing pattern in a medical intensive care unit in Qatar.

Objectives: The primary objectives were to evaluate the current usage of anti-microbial agents in the Medical Intensive Care Unit (MICU) of Hamad Medical Corporation (HMC) in Doha, State of Qatar and to correlate this with: a) the infectious disease pattern, b) the isolated microorganisms and their sensitivity pattern, and, importantly, c) the patient's clinical outcome. A secondary objective was to evaluate the influence of the use of steroid therapy on the development of fungal infections.

Methods: A prospective study covering a 2-month period from February through April 2004, including all patients admitted to the MICU for a minimum of 48 hours, and receiving a systemic antibiotic.

Gemella morbillorum endocarditis.

A case of Gemella morbillorum (G.morbillorum) endocarditis of the mitral valve in a patient with previously normal heart valves is reported. The presentation was subacute, and the infection was complicated by perforation of the posterior mitral leaflet that necessitated valve repair.

Clinical presentation of acute bacterial meningitis in Qatar.

Objective: To study the changes in the epidemiology of bacterial meningitis in the era of the Hemophilus influenzae (H. influenzae) type b vaccine and pneumoccous resistance.

Methods: Retrospective study which included patients admitted to Hamad Medical Corporation, Doha, Qatar between January 1998 through to December 2000 with positive cerebrospinal fluid culture.
