Summary: The study in public hospitals in Myanmar showed that implementing point-of-care HIV testing can improve survival rates for HIV-infected infants, but still faces challenges such as delayed sample reception and communication constraints among healthcare staff. Continuous focus on staff training, communication pathways and infrastructure is needed as plans for national scale-up evolve. Other models of care, such as allowing non-laboratory-trained personnel to perform POC testing and cost effectiveness, should also be evaluated.

Summary: In the Namibia population-based HIV impact assessment, the feasibility of near POC EID testing using GeneXpert platform was compared with the standard Roche COBAS AmpliPrep/COBAS TaqMan platform. The results showed 100% concordance between GeneXpert and Roche platforms, with GeneXpert having shorter average turnaround time and no sample failures, making it suitable for national-level POC EID testing.

Summary: The study describes the extent and variables associated with indeterminate HIV-PCR results and final HIV status in South Africa's early infant diagnosis program. The study found that missed diagnostic opportunities, diagnostic dilemmas, and delays in making a definite diagnosis are significant burdens for HIV-infected infants.

Summary: The targeted near-POC viral load testing in large HIV clinics in Lilongwe, Malawi showed that it enabled prompt clinical action, effectively managing patients. Although the all-in cost for near-POC testing was slightly higher compared to centralized testing, combining both methods in an optimized national program could further reduce the cost difference.

Summary: A study conducted in a hard-to-reach fishing community in Uganda identified factors associated with receiving early infant diagnosis (EID) tests for HIV-exposed infants. The study found that being under the care of a single mother and cessation of breastfeeding were significantly associated with not receiving the first DNA PCR test. The findings highlight the importance of enhancing early diagnosis services for infants in fishing communities.

Summary: A study conducted in Zambia showed that point-of-care (POC) early infant diagnosis (EID) can eliminate diagnostic delays and accelerate the initiation of antiretroviral therapy (ART). However, despite a high rate of ART initiation, the results did not show significant improvement in 12-month outcomes. Therefore, in settings where centralized EID is well functioning, POC EID is unlikely to improve pediatric HIV outcomes.

Summary: This scoping review summarizes the available evidence on the cost and cost-effectiveness of HIV early infant diagnosis (EID). The results suggest that most interventions designed to improve EID are cost-effective or cost-saving. However, comparing costs across studies is challenging due to heterogeneity in reporting. More studies are needed to capture the costs and benefits of delivering EID services in real-world settings.

Summary: The study evaluated the performance of Xpert EID as a consecutive test for HIV-exposed infants, showing high sensitivity, specificity, and positive predictive value, which can help reduce the rate of indeterminate results and improve accuracy.

Summary: The study identified various factors that hinder or facilitate the delivery and uptake of Early Infant Diagnosis (EID) of HIV services, including challenges within the health system and positive attitudes of health workers and mothers towards EID. Addressing these factors is crucial in improving the coverage of EID services in Sub-Saharan Africa, such as Ghana.

Summary: In this study, parallaxes from Gaia Early Data Release 3 were used to determine distances for 37 nearby Milky Way Cepheids. The distances obtained were found to be significantly different from geometric distances according to detached eclipsing binaries. The analysis suggests that the systematic uncertainties in the EDR3 parallaxes, combined with the uncertainties in the effect of metallicity on the Cepheid distance scale, result in a systematic error floor of approximately 3%. Therefore, the EDR3 data is currently not accurate enough to determine extragalactic distances precise to the 1% level.

Summary: POC EID in inpatient settings can increase testing volume, improve timely initiation of ART for HIV-positive infants, and reduce mortality rates. This study highlights the importance of expanding POC platforms for pediatric wards to improve early infant diagnosis and linkage to treatment.

Summary: This study aimed to determine early diagnostic methods for spinal tuberculosis. The results showed that GeneXpert MTB/RIF had a higher positive rate in diagnosis, and the tuberculosis-specific antigen/phytohemagglutinin ratio in the T-SPOT assay could predict and diagnose spinal tuberculosis effectively. Combining these two methods can lead to more accurate diagnosis of spinal tuberculosis.

Summary: Implementing point-of-care testing for early infant HIV diagnosis in rural Zambia through a hub-and-spoke model required significant investment in infrastructure, training, and supervision. However, it proved to be effective in rapidly diagnosing HIV-infected infants and facilitating early treatment initiation.

Summary: Early diagnosis and treatment of newborns with HIV can reduce mortality rates significantly. In low- and middle-income countries, scarce resources are required for processing HIV tests, leading to delays. This study presents a supply chain network model to optimize sample referral and minimize infant mortality due to delayed test results, using queuing theory and mathematical modeling. The proposed framework considers non-stationarity in resources and provides insights for managing sample referral networks in LMICs with limited resources.
