Introduction: Human papillomavirus (HPV) causes cervical cancer, and HPV vaccination is highly effective in preventing vaccine-targeted HPV infection. However, low HPV vaccination coverage in Kisumu County, Kenya, at about 10% for the first dose, highlights the critical issue of vaccine hesitancy, particularly in low and middle-income countries.

Methods: This study explores the concerns, myths and barriers to HPV vaccine uptake among adolescent girls (aged 10-14) enrolled at human immune-deficiency virus comprehensive care clinics and their parents in Kisumu County.

While the incidence of cervical cancer has dropped in high-income countries due to organized cytology-based screening programs, it remains the leading cause of cancer death among women in Eastern Africa. Therefore, the World Health Organization (WHO) now urges providers to transition from widely prevalent but low-performance visual inspection with acetic acid (VIA) screening to primary human papillomavirus (HPV) DNA testing. Due to high HPV prevalence, effective triage tests are needed to identify those lesions likely to progress and so avoid over-treatment.

Article Synopsis
  • - The study explored how perceptions impact COVID-19 vaccination uptake among 115 pregnant women in Kenya, revealing a 73% vaccination rate and 41.4% vaccine hesitancy.
  • - Data collected through an online questionnaire indicated that while most participants were educated and knowledgeable about vaccines, concerns about effectiveness and discouragement from peers influenced their decisions.
  • - The findings highlight the importance of addressing attitudes towards vaccination and leveraging social networks in promoting vaccine uptake, suggesting WhatsApp could effectively disseminate reliable information.

Background: Of women with cervical cancer (CC) and HIV, 85% live in sub-Saharan Africa, where 21% of all CC cases are attributable to HIV infection. We aimed to generate internationally acceptable facility-based indicators to monitor and guide scale up of CC prevention and care services offered on-site or off-site by HIV clinics.

Methods: We reviewed the literature and extracted relevant indicators, grouping them into domains along the CC control continuum.

Article Synopsis
  • A study was conducted with 39 women in Western Kenya who have HIV and are receiving antiretroviral therapy, focusing on HIV-1 RNA levels in the genital tract.
  • The research aimed to measure HIV shedding before and after treatment with cryotherapy for cervical lesions.
  • Results showed that most HIV shedding occurred before cryotherapy, indicating that the treatment itself was not the main reason for the shedding.

Background: Eclampsia, considered as serious complication of preeclampsia, remains a life-threatening condition among pregnant women. It accounts for 12% of maternal deaths and 16-31% of perinatal deaths worldwide. Most deaths from eclampsia occurred in resource-limited settings of sub-Saharan Africa.

Cardiac disease is an important life-threatening complication during pregnancy. It is frequently seen in pregnant women living in resource-limited areas and often results in premature death. The aim of this hospital-based longitudinal study was to identify factors related to adverse maternal and neonatal outcomes in pregnant women with cardiac disease in low-resource settings.

Background: Screening of unvaccinated women remains essential to mitigate the high morbidity/mortality of cervical cancer. Here, we compared visual inspection with acetic acid (VIA), recommended by WHO as the most cost-effective screening approach in LMICs, with HPV-based screening, and usage of p16/Ki-67 dual stain cytology.

Methods: We prospectively enrolled women participating in a VIA-based cervical cancer screening program in two peri-urban health centers of Kenya.

To provide information on the development of a gynecologic oncology training program in a low-resource setting in Kenya. This is a review of a collaboration between Kenyan and North American physicians who worked together to develop a gynecologic oncology training in Kenya. We review the published data on the increase of cancer incidence in sub-Saharan Africa and outline the steps that were taken to develop this program.

Purpose: Cervical cancer screening has been successful in reducing the rates of cervical cancer in developed countries, but this disease remains the leading cause of cancer deaths among women in sub-Saharan Africa. We sought to understand factors associated with limited uptake of screening services in our cervical cancer-screening program in Western Kenya.

Participants And Methods: Using items from a previously validated cancer awareness questionnaire repurposed for use in cervical cancer and culturally adapted for use in Kenya, we interviewed 2,505 women aged 18-55 years receiving care in gynecology clinics or seeking other services in 4 health facilities in Western Kenya between April 2014 and September 2014.
