Background & Objective: The present study was conducted on the prevalence of malaria as co-infection amongst 'asymptomatic HIV' and 'symptomatic HIV' subjects to see if such prevalence deviated from that commonly reported in apparently health individuals in same locality.
Methods: A prospective study that involved 196 participants grouped according to their HIV status as: 'asymptomatic HIV seropositive group' (n = 101); 'symptomatic HIV seropositive group' (n = 48) and 'control HIV-seronegative group (n = 47). Blood samples collected from the participants were used for double HIV screening by rapid immunoassay technique and immunochromatographic technique, and for the diagnosis of Plasmodium falciparum malaria using rapid P. falciparum antigen detection method.
Results: The result showed that the prevalence of P. falciparum malaria as a co-infection amongst the asymptomatic HIV seropositive group was 12 (11.8%) and amongst the symptomatic HIV seropositive group was 16 (33.3%). However, the prevalence rate of P. falciparum malaria amongst the control HIV seronegative group was 5 (10.6%) and the combined burden of P. falciparum malaria amongst both groups of HIV seropositives was 28 (18.9%).
Interpretation & Conclusion: The present study observed different prevalence rates of P. falciparum malaria amongst the three groups. The prevalence was tripled in symptomatic HIV seropositive group. This shows a clear departure from possible obtainable prevalence of malaria infection alone in this malaria endemic area. Due to the mortality rates associated with malaria infection in an endemic area, it may be necessary that routine malaria screening be adopted as part of the management policy to check the co-infection.

Background And Aims: People who have diabetes mellitus (DM) are thought to be more susceptible to pulmonary tuberculosis (PTB). Several published comparative investigations have reported that chest x-ray images from PTB with DM are considered atypical due to their frequent involvement of the lower lung field (LLF). This study aimed to investigate the frequency of lower lung field tuberculosis (LLF-TB) in DM and the risk factor of DM for the development of TB.

Background: Due to social-structural marginalization, sex workers experience health inequities including a high prevalence of sexually transmitted and blood-borne infections, mental health disorders, trauma, and substance use, alongside a multitude of barriers to HIV and substance use services. Given limited evidence on sex workers' broader primary healthcare access, we aimed to examine social-structural factors associated with primary care use among sex workers over 7 years.
Methods: Data were derived from An Evaluation of Sex Workers Health Access (AESHA), a community-based open prospective cohort of women (cis and trans) sex workers in Metro Vancouver, from 2014 to 2021.
Harmony in healthcare: recommended infant feeding practices and associated factors among HIV positive mothers in Eastern Ethiopian hospitals.

Background: For mothers identified as HIV-infected, recommended infant feeding practices must prioritize the highest likelihood of ensuring HIV-free survival for their children while preserving maternal health. Consequently, understanding the feeding status during critical infancy stages, especially under the risk of HIV, plays a crucial role in enhancing the quality of life within this specific population segment. Hence, this study was conducted to assess the magnitude and associated factors of recommended infant feeding practices and its associated factors among HIV-positive mothers in Eastern Ethiopian Hospitals.

Background: Fertility desire-based service guided by behavioral theory is a potential strategy to mitigate the HIV transmission risk, while related evidence remains scarce. We examined the long-term effect of theory-guided fertility desire-based services on HIV seroconversion between seropositive/seronegative partners in areas with high HIV prevalence and a cultural emphasis on fertility in China.
Methods: We established a retrospective cohort by recruiting 8,653 seropositive partners with seronegative partners between January 1, 2009, and December 31, 2020, in Liangshan, China.
