Factors associated with unsuccessful treatment outcomes among drug-resistant tuberculosis patients in Loreto, Peru, 2015–2023
In Loreto, Peru, unsuccessful treatment outcomes among patients with drug-resistant tuberculosis (DR-TB) remain high, underscoring the need to identify associated factors in this Amazonian region. This retrospective cohort study included 417 DR-TB cases registered in the national TB system in Loreto between 2015 and 2023. Loss to follow-up, death, and treatment failure were combined into a single composite outcome variable defined as unsuccessful…
Diagnostic accuracy study of the multiplex Truenat MTB Ultima/Covid-19 assay for simultaneous detection of Tuberculosis and Sars-CoV2 (Covid-19)
The COVID-19 pandemic led to significantly disrupted tuberculosis case detection and management. Additionally, overlapping symptoms, radiological findings and risk factors make differentiating tuberculosis and COVID-19 disease difficult. We conducted a prospective multicentre diagnostic accuracy study to determine sensitivity, specificity and operational characteristics of the Truenat MTB Ultima/COVID-19 assay, using a combined sputum plus nasoph…
Performance evaluation of the Molbio diagnostics Truenat MTB Ultima/Covid-19 multiplex assay for TB and Covid-19 case detection among people with symptoms suggestive of tuberculosis—a study protocol f…
Background: Tuberculosis (TB) remains a major public health problem globally, as reflected in persistently high morbidity and mortality rates. Current control efforts have been further complicated by the ongoing SARS-CoV-2 (COVID-19) pandemic. Rapid molecular diagnostics remain crucial to identifying the millions of people with undiagnosed TB. Objectives: The study aimed to determine the diagnostic accuracy of Truenat MTB Ultima/COVID-19 for the …

Objectives: The COVID-19 pandemic caused a global shortage of nasopharyngeal (NP) swabs, required for RT-PCR testing. Canadian manufacturers were contacted to share NP swab innovations. The primary objective was to determine whether novel NP test swabs were comparable to commercially available swabs regarding user characteristics, ability to collect a specimen, and diagnostic performance using RT-PCR testing. Methods: Participants were randomized…
Improving tuberculosis case detection through contact risk stratification by Xpert MTB/RIF Ultra and spatial parameters
Prompt diagnosis is critical for tuberculosis (TB) control, as it enables early treatment which in turn, reduces transmission and improves treatment outcomes. We investigated the impact on TB diagnosis of introducing Xpert Ultra as the frontline diagnostic test, combined with an innovative active-case finding (ACF) strategy (based on Xpert Ultra semi-quantitative results and spatial parameters), in a semi-rural district of Southern Mozambique. Fr…
Prediction models of Covid-19 fatality in nine Peruvian provinces
There are initiatives to promote the creation of predictive COVID-19 fatality models to assist decision-makers. The study aimed to develop prediction models for COVID-19 fatality using population data recorded in the national epidemiological surveillance system of Peru. A retrospective cohort study was conducted (March to September of 2020). The study population consisted of confirmed COVID-19 cases reported in the surveillance system of nine pro…
Optimizing the cascade of prevention to protect people from tuberculosis
The provision of tuberculosis preventive treatment is one of the critical interventions to reduce tuberculosis incidence and ultimately eliminate the disease, yet we still miss appropriate tools for an impactful intervention and treatment coverage remains low. We used recent data, epidemiological estimates, and research findings to analyze the challenges of each step of the cascade of tuberculosis prevention that currently delay the strategy impl…
Risk factors for disruptions in tuberculosis care in Uganda during the Covid-19 pandemic
Background : During the COVID-19 pandemic, TB mortality increased while diagnoses decreased, likely due to care disruption. In March, 2020, Uganda—a country with high TB burden, implemented a COVID-19 lockdown with associated decrease in TB diagnoses. This study aims to examine patient level risk factors for disruption in TB care during the COVID-19 pandemic in Uganda. This retrospective cross-sectional cohort study included six TB clinics in Uga…
Utilization of accessible resources in the fabrication of an affordable, portable, high-resolution, 3D printed, digital microscope for Philippine diagnostic applications
Philippine clinical laboratory licensing requirements mandate that diagnostic microscopy for Tuberculosis (TB) sputum microscopy, urinalysis, pap smears, wet smears, an option for complete blood count, stool exams, and malaria thick and thin smears should be accessible and available in health facilities including primary care centers. However, access to these essential diagnostics is hampered by the lack of trained personnel, relatively high cost…
Type 2 diabetes mellitus and antibiotic-resistant infections
Prevalence of positive TST among healthcare workers in high-burden TB setting in Peru
This study supports previous reports that TB infection is an occupational hazard for HCWs. Prevention of TB transmission through control measures, as well as timely diagnosis of LTBI in this particular high-risk group, is critical for individual and public health
Vulnerable populations and the right to health
Our study shows the need to go beyond developing a strong legal framework to ensure vulnerable populations such as indigenous people are able to realize their right to health. Governments need to allocate funds, improve training and adapt healthcare provision to the cultural, geographical, and social context of indigenous people
HIV Stigma as a Barrier to Retention in HIV Care at a General Hospital in Lima, Peru
Knowledge about HIV prevention and transmission among recently diagnosed tuberculosis patients
The study shows inadequate levels of knowledge about HIV transmission and prevention among newly-diagnosed TB patients in this setting, and underscores the need for implementing educational interventions in this population
