People living with HIV have a higher chance of developing TB, and once the disease has progressed, are at greater risk of having unfavorable TB treatment outcomes. Data on TB treatment outcomes among the HIV-associated TB population in Uzbekistan are limited.

Effectiveness and Safety of a Shorter Treatment Regimen in a Setting with a High Burden of Multidrug-Resistant Tuberculosis.

Treatment of drug-resistant tuberculosis is lengthy, insufficiently effective, and toxic. Since 2016, the World Health Organization has recommended shorter treatment regimens (STR). We assessed effectiveness and predictors of drug adverse events (DAE) among patients treated with STR.

Antimicrobial Resistance in a Tertiary Care Hospital in Armenia: 2016-2019.

Antimicrobial resistance (AMR) is the acquired ability of pathogens to withstand antimicrobial treatment. To bridge the gap in knowledge for implementing effective and targeted interventions in relation to the AMR in Armenia, we designed this study to explore the performance of AMR diagnostics and the profile of AMR in the Nork Infection Clinical Hospital (NICH) for the period of 2016-2019, particularly to (i) determine the proportions of antimicrobial resistance among all samples tested at the hospital laboratory, (ii) determine the proportion of resistance against specific antimicrobials, and (iii) identify factors associated with AMR. A cross-sectional study was conducted with a secondary data analysis that included all the patients tested for AMR in the laboratory of the NICH for the period of 2016-2019.

Depression and anxiety symptoms among people with rifampicin-resistant tuberculosis receiving in-patient care in the National Pulmonology Reference Institute in Romania.

Mental health comorbidities are common among tuberculosis patients, with higher prevalence among people with rifampicin-resistant/multidrug-resistant (RR/MDR) tuberculosis.  TB and depression share common risk factors adding to the overall disease burden. There is limited evidence about prevalence of depression and anxiety symptoms among tuberculosis patients in Romania.

Factors associated with loss to follow-up among people with tuberculosis in the country of Georgia: a cohort study.

Despite having universal access to tuberculosis (TB) treatment, loss to follow-up (LFU) rates remain high in Georgia, 6% among drug-susceptible TB (DS-TB) patients (2017 cohort) and 19% among drug-resistant TB (DR-TB) patients diagnosed in 2016. A cohort study was conducted to analyze secondary data from the Georgian National Tuberculosis Surveillance Database. Study population included adult (≥18 y.

Higher Surgery and Recovery Room Air Pressures Associated with Reduced Surgical Site Infection Risk.

Background: Incisional surgical site infections (SSIs) following coronary artery bypass grafting (CABG) prolong hospital stays, elevate healthcare costs and increase likelihood of further complications. High air pressure deactivates bacteria and is utilized for commercial food preservation, assuring microbiologically safe pharmaceuticals and sanitizing instruments. However, research on utilizing air pressure deactivation thresholds in surgical and postoperative rooms to reduce rates of SSIs is lacking.

Gaps in tuberculosis control in Armenia: How to improve the care system?

Introduction: Tuberculosis (TB) continues to be a global public health problem. People with weakened immune systems are more vulnerable to TB. It is one of the top 10 causes of death worldwide and is a leading cause of death for people living with HIV (PLWH).

Antiretroviral therapy among patients with HIV in Almaty, Kazakhstan: the implication for HIV-associated tuberculosis control.

Introduction: Antiretroviral therapy (ART) is an effective preventive strategy against tuberculosis (TB) in people living with HIV (PLWH). In Kazakhstan, according to the revised HIV treatment guideline (2017), ART should be initiated immediately after HIV diagnosis established, regardless of CD4+ count.

Aim: To evaluate the impact of early initiation of ART on TB infection in PLWH registered in the Center of Prevention and Control of AIDS, Almaty, Kazakhstan, between 2008 and 2018.

New approach for tuberculosis contact tracing implemented in the two regions of Kyrgyz Republic during 2017-2018.

Introduction: Tuberculosis (TB) contact investigation as a proved approach for finding new TB cases, is not fully performed in Kyrgyzstan. In 2018, the country started aligning the National Guidelines for tracking contacts with the WHO recommendations by expanding the definition for TB index cases to all close contacts, regardless of their TB risk status.

Methodology: This cross-sectional census aimed to determine the active case detection changes among TB contacts after implementation of a new TB tracing strategy using the National Surveillance data.
