Objective: To evaluate the impact of Truenat assays on the diagnosis of TB at peripheral facilities in Nigeria.
Methods: This was a retrospective cross-sectional study across 34 out of 38 Truenat-implementing facilities in Nigeria. These facilities offer DOTS services. Information on turnaround time (TAT) for TB diagnosis and time to commencement of treatment was obtained. Also, trends in TB case notifications at the facilities 9 months prior to and 9 months during Truenat implementation were compared.
Results: Of 2,335 entries, 70.1% (1,636) were used to determine TAT, while 45.8% ( = 1,070) were used for time to treatment initiation. The median time to diagnosis was <24 hours (IQR 0-1 days). The majority (57.9%) were diagnosed in <24 hours. The median time to treatment initiation was 1.5 days (IQR 0-3). In 9 months before the introduction of Truenat, 8% of 20,424 presumptives evaluated were positive for TB, while during the implementation, 9% of 37,087 presumptives were positive for TB.
Conclusion: Truenat deployment led to an increase in TB and DR-TB case detection in peripheral facilities in Nigeria. It also decreased TAT and time to TB treatment initiation. These have positive implications in the fight against TB, and Truenat is relevant in finding missing TB cases in Nigeria.

Introduction: Tuberculosis (TB) continues to be a major health concern that has a significant impact on morbidity and mortality worldwide. Tubercular meningitis (TBM) may be fatal due to its severe neurological outcomes if not diagnosed and treated promptly. The newer molecular diagnostic techniques have brought significant advancements in the detection of (MTB).

Background: In 2020, the WHO-approved Molbio Truenat platform and MTB assays to detect Mycobacterium tuberculosis complex (MTB) and resistance to rifampicin directly on sputum specimens. This primary health care center-based trial in Mozambique and Tanzania investigates the effect of Truenat platform/MTB assays (intervention arm) combined with rapid communication of results compared to standard of care on TB diagnosis and treatment initiation for microbiologically confirmed TB at 7 days from enrolment.
Methods: The Tuberculosis Close the Gap, Increase Access, and Provide Adequate Therapy (TB-CAPT) CORE trial employs a pragmatic cluster randomized controlled design to evaluate the impact of a streamlined strategy for delivery of Truenat platform/MTB assays testing at primary health centers.

Purpose: The COVID-19 pandemic was unique in the history of outbreaks because of the massive scaling up of resources related to diagnostics, treatment modalities, and vaccines. To understand the impact of the pandemic among laboratory professionals, we aimed to conduct a survey to assess the improvement in the lab capacity post-covid in terms of infrastructure and accreditation status across various levels of hospitals and to determine the changes in the practice of infection control precautions during the pandemic.
Methods: This was an anonymous, online-based survey (using 58 item questionnaire) conducted between July 09, 2021, and August 07, 2021.

Background: Programmes that introduce rapid molecular tests for tuberculosis and tuberculosis drug resistance aim to bring tests closer to the community, and thereby cut delay in diagnosis, ensure early treatment, and improve health outcomes, as well as overcome problems with poor laboratory infrastructure and inadequately trained personnel. Yet, diagnostic technologies only have an impact if they are put to use in a correct and timely manner. Views of the intended beneficiaries are important in uptake of diagnostics, and their effective use also depends on those implementing testing programmes, including providers, laboratory professionals, and staff in health ministries.
