Background and objective: Urinary tract infections (UTIs) are the most common minor complication after operations, mostly due to bladder catheterization that used routinely during operations. This investigation seeks to determine prevalence rate, bacterial features, antibiotic sensitivity and risk factors for urinary tract infection in postoperative patients in tertiary hospitals in Sana’a, Yemen. Methods: This prospective analysis included 390 patients undergoing surgery between 2017 and 2018 at Al-Thawra Hospital. The study includes 258 male and 132 female between the ages 5 to 80 years. Clinical and demographic data and factors affecting UTIs were collected in the standard questionnaire, and the sample was obtained after catheter removal; or, in patients with a clinical indication of continuous catheterization, a sample was obtained after the replacement of a new catheter. The samples were cultured, examined for significant possible bacterial pathogens, isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method. The operative characteristics associated with postoperative UTI were also analysis. Results: Postoperative UTI (POUTI) occurred in 144/390 (37%), and the predominant post-operative uropathogen was Escherichia coli (34%), followed by Pseudomonas aeruginosa 1(27%) and Staphylococcus coagulase negative (16.7%). In Gram-negative bacteria, high resistance to ampicillin (95%), nalidixic acid (63%), ceftriaxone (68%) and cotrimoxazole (55%) was recorded, while high sensitivity to amikacin (98%) and ciprofloxacin. (84%), cefotaxime (87%), gentamicin (87%) and imipenem (98%). In Gram-positive bacteria, high resistance to penicillin (90%), erythromycin (85%), and amoxicillin (78%) was recorded, while high sensitivity to aztreonam (94%), augmentin (83%),   ciprofloxacin (93%), cefotaxime (86%), gentamicin (85%), Rifampicin (100%) and vancomycin (97%).  The following characteristics are independently associated with postoperative UTI: female sex (OR 2.1, 95% CI 1.3–3.2), Rubber PTFE catheter (OR 4.7, 95% CI 1.99–11.4), longer duration of catheterization >10 days (OR 4.4, 95% CI 2.3–8.3), overweight (OR 1.7, 95% CI 1.1–2.9), and emergency surgery  (OR 1.9, 95% CI 1.2–3.0). Conclusions: POUTI remains an important problem in our hospitals and what complicates the situation is that all the causative microorganisms are MDR with few treatment options; and several risk factors were independently associated with POUTI.

Objectives:  Lower respiratory infections (LRTIs) are the leading reason of death infectious diseases in the world and the fifth leading cause of death in general. The study aimed to identify the general characteristics of LRTI, the causative bacteria and the results of sensitivity to antibiotics. Subjects and methods:  A multicentre prospective study was performed at 3 University hospitals. The study included 555 clinical diagnostic cases as LRTI cases, 328 male and 227 female, aged 3 to 69 years. Clinical and demographic data were collected in the standard questionnaire, and samples included sputum or bronchial lavage (BAL) staining and culture. Samples were cultured in 3 different bacterial media, blood agar and LJ slope, chocolate agar with Co2; cultures were then examined for possible bacterial pathogens of LRTI. Possible bacterial pathogens were isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method. Results:  LRTI was recorded among all age groups and with less frequency in children less than 16 years of age. A large number of LRTI (36.2%) was not diagnosed, most in CAP (52.4%), followed by HAP (33.9%) while unidentified cases were lower in AECOPD (22.8%). CAP isolates are K. pneumoniae (26.2%), S. pyogens (12.3%), and S. pneumoniae (9%); in HAP are MSSA (24%), E. Coli (12.9%), MRAS (11.1%), K. pneumoniae (10.5%) and P. aeruginosa (7%); and in AECOPD are M. catarrhalis (47.2%), K. pneumoniae (17.2%), H. influnzae (10.7%) and P. aeruginosa (2%). In Gram-positive bacteria, high resistance to ampicillin/sulbactam (100%) and amoxicillin/clavulanate (100%) was recorded, while moderate resistance to amikacin, vancomycin, cefepime and moxifloxacin was recorded. In Gram-negative bacteria, a high resistance to 3rd g Cephalosporin’s  (68.5%) was recorded, while a moderate sensitivity to the other antibiotics tested was recorded. Conclusion:  There is a high rate of undiagnosed LRTI in Yemen and this highlights the need for health authorities to develop strategies to diagnose most of the causes of LRTI, including Mycoplasma, Chlamydia, and viral causes. No antibiotics are completely effective in treating LRTI in our area and antibiotic sensitivity should be performed in all cases.

Background: Hepatitis B virus (HBV) is a most important health problem, it's a global pandemic. Previous surveys showed a high prevalence of hepatitis B infection in Yemen. Hepatitis B vaccination is the most efficient way to prevent hepatitis B virus infection and its outcomes (such as hepatocellular carcinoma, cirrhosis, and liver failure). Aim: To measure the immune status of hepatitis B virus amongst first-year students at the faculties of Thamar University during the academic year 2021-2022. Methods: A total 196 of first-year students participated in this cross-sectional study and tested for anti-HBsAg and the antibody to HBV core antigen (anti-HBc) and HBsAg by using ELISA during the period from January to May 2022 at Thamar University. An anti-HBs antibody titer ≥10 mIU/mL was regarded as being protective against HBV infection. Results: In this study, 22.4% of the students had protective levels against hepatitis B, while 77.6% had a non-protective level. HBV markers showed that 19.90%, 2.55%, and 75.51% of the students had been vaccinated and immunized due to a previous infection and exposed to HBV infection respectively and only 2.04% of them were non-obvious cases. The prevalence of anti-HBc was 4.6%. Risk factors that showed statistical significance were found between positive anti-HBc and family history of HBV (p=0.01). Conclusion: The low prevalence of hepatitis B protection levels in Thamar University medical students needs further research and necessitates implementation of a screening and vaccination program for all non-immunized healthcare students.                         Peer Review History: Received: 24 December 2022; Revised: 13 February 2023; Accepted: 8 March 2023, Available online: 15 March 2023 Academic Editor: Dr. Iman Muhammad Higazy, National Research Center, Egypt, imane.higazy@hotmail.com Received file:                             Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewers: Rola Jadallah, Arab American University, Palestine, rola@aauj.edu Dr. Wadhah Hassan Ali Edrees, Hajja University, Yemen, edress2020@gmail.com Similar Articles: PREVALENCE OF HEPATITIS A VIRUS, HEPATITIS B VIRUS, AND HEPATITIS C VIRUS, AMONG PATIENTS WITH HEPATIC JAUNDICE IN SANA’A CITY, YEMEN: A HOSPITAL BASED STUDY PREVALENCE OF DIFFERENT HEPATITIS B VIRUS GENOTYPES AND RISK FACTORS ASSOCIATED AMONG SELECTED YEMENI PATIENTS WITH CHRONIC HEPATITIS B INFECTION
