Gender, health-seeking, and tuberculosis
Tuberculosis (TB) remains a persistent public health concern in Peru, particularly in densely populated urban districts marked by poverty, informal labor, and overcrowded housing. Drawing on 25 semi-structured interviews with adult residents insured under the public health system (Seguro Integral de Salud) in San Juan de Lurigancho, Lima, this article examines how gender norms shape everyday understandings of TB, health-seeking practices, and mor…
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 …
Fighting tuberculosis hand in hand
Tuberculosis (TB) is an infectious disease closely intertwined with stigma, discrimination, and the social determinants of health. Communities of people affected by TB are experts in their care pathways, but the TB field continues to fall short of meaningfully engaging communities in TB research. This is a missed opportunity to improve the quality, relevance, person-centeredness, positive impact, and sustainability of TB research outputs. We ackn…
Original article
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…
The community as an active part in the implementation of interventions for the prevention and care of tuberculosis
Interventions involving direct community stakeholders include a variety of approaches in which members take an active role in improving their health. We evaluated studies in which the community has actively participated to strengthen tuberculosis prevention and care programs. A literature search was performed in Pubmed, Scopus, ERIC, Global Index Medicus, Scielo, Cochrane Library, LILACS, Google Scholar, speciality journals, and other bibliograph…
Diagnostic performance of four lateral flow immunoassays for Covid-19 antibodies in Peruvian population
Serological assays have been used in seroprevalence studies to inform the dynamics of COVID-19. Lateral flow immunoassay (LFIA) tests are a very practical technology to use for this objective; however, one of their challenges may be variable diagnostic performance. Given the numerous available LFIA tests, evaluation of their accuracy is critical before real-world implementation. We performed a retrospective diagnostic evaluation study to independ…
Situación de la comorbilidad tuberculosis y diabetes en personas adultas en el Perú, 2016-2018
DM is the most frequent comorbidity in patients with TB in Peru, although no association with higher mortality was found
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
Interventions for the prevention of risk factors and incidence of type 2 diabetes in the work environment
OBJECTIVE: To evaluate the effectiveness of interventions aimed at the prevention of risk factors and incidence of type 2 diabetes in the workers population. METHODS: Systematic review of interventions aimed at adult workers at risk of type 2 diabetes published in Medline, Embase, Web of Science, Central Cochrane Registry of Controlled Trials, and Lilacs. Randomized trials, quasi-experimental research and cohort studies were selected; in English,…
Comorbilidad de tuberculosis y diabetes
Co-morbidity between tuberculosis and diabetes has been described since the early 20th century. In developed countries, where there has been a decrease of infectious diseases with an increase of non-communicable diseases, as well as those countries who still have a high prevalence of infectious diseases but an increase of non-communicable diseases, it is observed that the prevalence of co-morbidity between tuberculosis and diabetes is increasing,…
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
Conocimientos, actitudes y prácticas sobre la enfermedad de Carrión en población rural de Ancash, Perú
Even though these three communities have a history of Carrión's disease, their inhabitants did not demonstrate adequate knowledge, attitudes, or practices for preventing it. In view of this, and given that this illness has cyclical outbreaks, it is imperative to design and implement a program to educate residents of these communities-focusing on the role of habits and customs-about how to prevent Carrión's disease, as well as the region's other m…
