Understanding malaria treatment patronage from informal healthcare providers in Nigerian urban settlements: insights from community members and providers.

Background: Informal Healthcare Providers (IHCPs), including Proprietary Patent Medicine Vendors (PPMVs), drug peddlers, traditional healers, and herbal drug sellers are often the first choice for malaria treatment, especially in urban slums. Unplanned urbanization significantly impacts malaria transmission by creating cities with inadequate safety nets and healthcare access, increasing reliance on IHCPs. While the World Health Organization recognizes IHCP's crucial role and emphasizes integrating them into formal healthcare for improved malaria care, they lack requisite training in malaria management and operate outside official regulations, raising concerns about the quality of care they provide.

Detection of High-Risk Human Papillomavirus Genotypes Among HIV-Infected Women in Four States in Nigeria.

Introduction The World Health Organization states that almost all cervical cancer cases are linked to infection with high-risk human papillomaviruses transmitted through sexual contact. Implementing effective surveillance and preventive measures would enable the prevention of most cervical cancer cases, especially in HIV-infected women. Every year, about 12,000 women in Nigeria are diagnosed, with almost 8,000 deaths.

Designing a Collaborative Breast Radiology Training Program to Tackle Tanzania's Breast Cancer Crisis.

Breast cancer incidence and mortality continue to increase in Africa. In Tanzania, breast cancer is the second leading cause of cancer death for women, and breast cancer incidence and mortality are projected to increase by 80% by 2030. Education gaps among health care workers, delayed presentation, limited screening, and low health literacy all pose significant challenges to providing optimal breast cancer care.

The V-BRCH Project: Strengthening HIV Research Capacity in Nigeria through Intensive Workshops in Implementation Science and Grant Writing.

As persons with HIV live longer as the result of antiretroviral therapy, morbidity from HIV-associated noncommunicable diseases (NCDs) is increasing. The Vanderbilt-Nigeria Building Research Capacity in HIV and Noncommunicable Diseases program is a training platform created with the goal of training a cohort of successful Nigerian investigators to become leaders in HIV-associated NCD research. We describe survey findings from two week-long workshops in Kano, Nigeria, where trainees received instruction in implementation science and grant writing.

Prevalence of Cytopenia and its Correlation with Immunosuppression in Naïve HIV-1 Infected Patients Initiating First-Line Antiretroviral Therapy: A Pilot Study.

This study aimed to assess the prevalence of cytopenias and their correlation with the level of immunosuppression in treatment-naive HIV-infected participants after initiating highly active combined antiretroviral drug therapy (cART24).

Materials And Methods: This prospective study focused on evaluating cytopenia in 44 treatment-naive HIV-infected patients who consented to initiate cART and were consecutively enrolled.

Novel Complex of Zinc (II) Dichloroethylenediamine: Synthesis, Characterization, In-silico, and In-vitro Evaluation against Cervical Cancer Cells.

Objective: Cervical cancer is a malignancy originating from the cervix and often caused by oncogenic Human Papilloma Virus (HPV), specifically subtypes 16 and 18. Anticancer drugs are chemotherapeutic compounds used for cancer treatment. Therefore, this research aims to synthesize and characterize Zinc (II) dichloroethylenediamine (Zn(en)Cl2) complex, as well as determine its antiproliferative activity against HeLa cells.

Effects of anti-retroviral therapy on baseline serum interleukin-18 levels in HIV-I infected patients relative to viral suppression and CD4+ gain: A prospective pilot study.

Background: In HIV infection, dysregulation of cytokines, including interleukin 18 (IL-18), has been linked to poor clinical outcomes in studies mainly conducted in resource-rich countries. This phenomenon has not been well-studied in resource-limited settings where outcomes could be confounded by exposure to endemic infections and genetic factors.

Objectives: Therefore, the influence of immunological and virological status of HIV-infected, antiretroviral therapy (ART)-naïve patients on serum IL-18 levels at baseline (pretreatment) and 24 weeks following initiation of combination ART (cART24) in a resource-limited setting was investigated.
