Skin Carotenoid Scores Reflect Immune Status Among Children Living With Hiv In Tanzania, Wilbert Mbuya, Thobias Boniphace, Michael Mwagala, Peter Agrea, Nazareth M Mbilinyi, Nancy E Moran, Andrew R Dinardo, Mkunde Chachage

Children’s Nutrition Research Center Staff Publications

Many individuals living with HIV experience persistent inflammation despite antiretroviral treatment, increasing their risk for cardiovascular diseases, cognitive decline, and other noncommunicable diseases. Carotenoids can inhibit this inflammation by reducing lipid peroxidation. Carotenoid intake and plasma concentrations can be approximated using a noninvasive cutaneous spectrophotometer. This study quantified skin carotenoid levels in Tanzanian children ages 5 to 15 years old (N = 185) both with and without HIV. Over 95% had low to moderate skin carotenoid scores (< 400 units). In children living with HIV, higher viral loads were linked to lower skin carotenoid scores (rho = -0.57, P < 0.001), whereas higher CD4 counts correlated with increased skin carotenoid scores (rho = 0.52, P < 0.001). Overall, carotenoid levels were low and associated with immune status, suggesting that elevated carotenoid scores correlate with lower inflammation in children living with HIV. Future studies investigating dietary carotenoid interventions to support immune function are warranted.

Optimization Of Pediatric Multidetector Ct Imaging Parameters Using A Machine Learning–Based Monte Carlo Simulation Model, Ali O. Masoud, Adithya Rajnaryanan, Khamis O. Amour, Ahmed M. Jusabani, Justin E Ngaile, Manoj Kumar, Mwingereza John Kumwenda Dr

Tanzania Journal of Science

This study utilized Monte Carlo (MC) simulations to optimize radiation doses in pediatric multidetector computed tomography (MDCT) head scans by analyzing key parameters like tube current (mA), tube voltage (kV), pitch, and slice thickness. The findings indicate that reducing tube current significantly lowers the Computed Tomography Dose Index (CTDIvol) and Dose Length Product (DLP), effectively minimizing patient radiation exposure. Higher pitch values (0.7–0.9) further reduced radiation by decreasing beam overlap, while using a thinner slice thickness (0.6 mm) improved dose efficiency. A comparison highlighted the effectiveness of optimization: simulated parameters kVp 100, mAs 81, pitch 0.98 yielded a CTDIvol of …

A Review Of Yellow Fever: Epidemiology, Pathogenesis, Clinical Manifestations, Treatment, Prevention, And Prognosis, Farah Ebrahim, Samina Somji, Reena Shah, Salim Surani

Internal Medicine, East Africa

Yellow fever is a mosquito-borne viral illness caused by the yellow fever virus (YFV), a member of the Flaviviridae family. Despite the availability of an effective live-attenuated vaccine, the disease remains endemic in regions of Africa and South America. Transmission occurs primarily via an infected mosquito called Aedes aegypti, with distinct urban, sylvatic, and intermediate transmission cycles. Clinically, infection ranges from mild febrile illness to severe disease, which is characterized by jaundice, hemorrhage, and multiorgan failure. Pathogenesis involves viral replication in hepatocytes, immune-mediated injury, and dysregulated inflammatory responses, leading to characteristic hepatic mid-zone necrosis. Diagnosis relies on molecular detection …

Otolaryngology (ENT) Resident Research

Head and neck cancer care delays are challenging, given the complexity of cancer care pathways, which leads to delays throughout the patient journey, from the symptom onset to treatment completion. Current models and literature addressing cancer care are limited by heterogeneous definitions of care intervals, a focus on specific aspects of the patient journey instead of the whole care continuum, and limited use of implementation science to target gaps in implementing evidence-based interventions. Here, we propose the Head and Neck Cancer TImely aCess TO Care Model as an approach to conceptualize, measure, and address delays in diverse health systems.
