Treatment modification after second-line failure among people living with HIV in the Asia-Pacific.

Background: The World Health Organization recommends continuation with the failing second-line regimen if third-line option is not available. We investigated treatment outcomes among people living with HIV in Asia who continued with failing second-line regimens compared with those who had treatment modifications after failure.

Methods: Treatment modification was defined as a change of two antiretrovirals, a drug class change or treatment interruption (TI), all for >14 days.

Nosocomial Coronavirus Disease Outbreak Containment, Hanoi, Vietnam, March-April 2020.

We report on the public health response generated by an outbreak of coronavirus disease (COVID-19) that occurred during March 2020 at Bach Mai Hospital (BMH) in Hanoi, northern Vietnam's largest hospital complex. On March 18, a total of 3 distinct clusters of COVID-19 cases were identified at BMH. Diagnosis of the initial 3 COVID-19 cases led to contact tracing, symptom screening, and testing of 495 persons and limited quarantine of affected institutes or departments.

Prevalence of Opportunistic Infections and Associated Factors in HIV-Infected Men Who Have Sex With Men on Antiretroviral Therapy in Bach Mai Hospital, Hanoi, Vietnam: A Case-Control Study.

Objective: To investigate the distribution of opportunistic infections (OIs) and factors associated with acquiring OIs in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) in comparison to those of heterosexual patients.

Method: A cross-sectional study was conducted on 82 HIV-infected MSM and 120 HIV-infected heterosexual men in Bach Mai Hospital, Hanoi, Vietnam. Demographical characteristics and clinical data were collected and analyzed using appropriate statistics (Mann-Whitney, Chi-square, Fisher's exact test, and logistic regression).

A clinic-based direct real-time fluorescent reverse transcription loop-mediated isothermal amplification assay for influenza virus.

Seasonal influenza virus causes acute respiratory tract infections, which can be severe in children and the elderly. At present, rapid influenza diagnostic tests (RIDTs) are popular at clinical sites because they enable early diagnosis and avoid unnecessary use of antibiotics; in addition, high risk patients with underlying disease can be given antiviral drugs. However, the sensitivity and specificity of some of those tests are relatively poor.

Erythropoietin during porcine aortic balloon occlusion-induced ischemia/reperfusion injury.

Background: Aortic occlusion causes ischemia/reperfusion injury, kidney and spinal cord being the most vulnerable organs. Erythropoietin improved ischemia/reperfusion injury in rodents, which, however, better tolerate ischemia/reperfusion than larger species. Therefore, we investigated whether erythropoietin attenuates porcine aortic occlusion ischemia/reperfusion injury.

Hemodynamic and metabolic effects of hydrogen sulfide during porcine ischemia/reperfusion injury.

In awake spontaneously breathing mice, inhaling gaseous hydrogen sulfide (H2S) produced a "suspended animation-like" metabolic status with hypothermia and reduced O2 demand, thus protecting from lethal hypoxia. Murine models may be questioned, however, because due to their large surface area/mass ratio, rodents can rapidly drop their core temperature. Therefore, we investigated whether intravenous H2S (Na2S, sodium sulfide) would induce a comparable metabolic response in anesthetized and mechanically ventilated pigs.
