AI Article Synopsis
- High rates of antimicrobial resistance (AMR) are prevalent in Southeast Asia, but limited data exists for Timor-Leste, prompting this study to analyze AMR in bacteria from urine and skin swabs in Dili.
- The study processed 154 urine and 57 skin isolates, revealing that 35% of Enterobacteriaceae were resistant to ceftriaxone, while no carbapenem-resistant Gram-negative isolates were found, and 11% of Staphylococcus aureus were identified as CA-MRSA.
- The findings highlight a notable presence of ESBL-producing Gram-negative bacteria but a lower rate of methicillin-resistant S. aureus, indicating the need for better understanding and management of AMR in Timor-L
Article Abstract
Objectives: High rates of antimicrobial resistance (AMR) are seen throughout Southeast Asia. However, limited AMR data exist for Timor-Leste, which is situated on the south-eastern portion of the Malay Archipelago. The purpose of this study was to identify AMR in bacteria isolated from urine and skin swabs from patients in Dili, the capital of Timor-Leste.
Methods: Urine and skin swabs were collected from symptomatic patients in Timor-Leste and were processed for bacterial culture. Isolates were processed in Australia using a VITEK2 system for bacterial identification and to determine antimicrobial susceptibility according to Clinical and Laboratory Standards Institute (CLSI) guidelines.
Results: A total of 154 urine isolates and 57 skin isolates were analysed. Of the Enterobacteriaceae, 35% were resistant to ceftriaxone with an extended-spectrum β-lactamase (ESBL)-producing phenotype. Carbapenem resistance was not observed in any of the Gram-negative isolates. Of the Staphylococcus aureus isolates, 11% were of the community-associated methicillin-resistant S. aureus (CA-MRSA) phenotype.
Conclusions: A moderately high proportion of Gram-negative urine isolates in Timor-Leste demonstrate phenotypic ESBL production, and a relatively low proportion of S. aureus isolates were methicillin-resistant. Improved understanding of AMR rates in Timor-Leste can help guide antimicrobial prescribing and inform antimicrobial stewardship strategies.

Background: In acquired immunodeficiency syndrome patients, Talaromyces marneffei infections are mostly disseminated and may involve the skin, mucosa, respiratory system, digestive system, lymphatic system, and as some reports indicate, the nervous system. Mp1p, a cell wall-specific polysaccharide in Talaromyces marneffei, is used for laboratory diagnosis of Talaromyces marneffei in blood and urine samples. However, Cerebrospinal fluid Mp1p diagnosis of Talaromyces marneffei central nervous system infection has not been reported.

High ambient heat can directly influence blood pressure (BP) through the vasodilation of the skin vasculature and indirectly by affecting urinary volume and electrolyte levels. We evaluated the direct and urine electrolyte-mediated effects of ambient temperature on BP. We pooled 5,624 person-visit data from a community-based stepped-wedge randomized control trial in southwest coastal Bangladesh from December 2016 to May 2017.

Objective: The current management for complex urethral strictures commonly uses open reconstruction with buccal mucosa urethroplasty. However, there are multiple situations whereby buccal mucosa is inadequate (pan-urethral stricture or prior buccal harvest) or inappropriate for utilization (heavy tobacco use or oral radiation). Multiple options exist for use as alternatives or adjuncts to buccal mucosa in complex urethral strictures (injectable antifibrotic agents, augmentation urethroplasty with skin flaps, lingual mucosa, bladder mucosa, colonic mucosa, and new developments in tissue engineering for urethral graft material) (1, 2).
