Pathways to prevention: insights on stemming HIV outbreaks in Larkana, Pakistan.

In the past two decades, Pakistan has faced multiple human immunodeficiency virus outbreaks, with Larkana appearing to be the hub of such outbreaks. While the previous Larkana outbreaks happened in high-risk populations, the alarming outbreak in 2019 occurred in a low-risk paediatric population, raising several concerning questions. Human immunodeficiency virus infections spilling into the general population is indicative of a steady increase in the number of cases, and the failure of control strategies to stem the concentrated epidemic from evolving. Although several causative factors have been identified from previous outbreaks, the one that occurred in 2019 may have been influenced by an additional, hitherto unexplored factor; child sexual abuse. The current narrative review was planned to summarise human immunodeficiency virus risk factors and causes identified in previous Larkana epidemics, to explore potential reasons for the outbreaks in children, and to discuss possible steps needed for stemming human immunodeficiency virus outbreaks in Pakistan.

Reducing post-operative length of stay, is it worth the effort?

BACKGROUND: Studies show that reducing the length of hospital stay (LOS) for surgical patients leads to cost savings. We hypothesize that LOS has a nonlinear relationship to cost of care and reduction may not have a meaningful impact on it. We have attempted to define the relationship of LOS to cost of care. We utilized the itemized bill, generated in real time, for hospital services. MATERIALS: Adult patients admitted under General, Neuro, and Orthopedic surgery over a 3-month period, with an LOS between 4 and 14 days, were the study population. Itemized bill details were analyzed. Charges in Pakistani rupees were converted to US dollar. Ethical exemption for study was obtained. RESULTS: Of the 853 patients, 38% were admitted to General Surgery, 27% to Neurosurgery, and 35% to Orthopedics. A total of 64% of the patients had an LOS between 4 and 6 days; 36% had an LOS between 7 and 14 days. Operated and conservatively managed constituted 82% and 18%, respectively. Mean total charge for operated patients was higher $3387 versus $1347 for non-operated ones. LOS was seen to have a nonlinear relationship to in-hospital cost of care. The bulk of cost was centered on the day of surgery. This was consistent across all services. The last day of stay contributed 2.4%-3.2% of total charge. CONCLUSIONS: For surgical patients, the cost implications rapidly taper in the postoperative period. The contribution of the last day of stay cost to total cost is small. For meaningful cost containment, focus needs to be on the immediate perioperative period.

Diagnostic value of bronchoscopy in Sars-Cov-2 infection: A systematic review.

OBJECTIVE: To investigate the diagnostic performance of bronchoscopy in patients with coronavirus disease 2019 infection. METHODS: The systematic review was conducted in April 2021 and comprised search of published articles and preprint servers for original articles assessing diagnostic performance of bronchoscopy in patients with suspected coronavirus disease 2019 infection. The primary outcome of interest was diagnostic sensitivity of bronchoalveolar lavage in the patients. The quality of each study was assessed using the Quality Assessment, Data Abstraction and Synthesis-2 tool. RESULTS: Of the 29 full-text articles assessed for eligibility, 4(13.8%) were included collectively comprising 209 patients who had undergone bronchoalveolar lavage. Mean sensitivity of bronchoalveolar lavage was 83.5% ± 10.63 (range: 68.2-940%). Overall, the 4 studies had an unclear or low risk of bias. CONCLUSIONS: Limited data suggested that bronchoscopy with bronchoalveolar lavage did not have reliably higher diagnostic sensitivity than that reported for either nasopharyngeal or oropharyngeal swabs.
