Article Synopsis
  • Major depressive disorder (MDD) is associated with changes in brain structure and synaptic function, particularly in limbic regions.
  • Astrocytes, brain cells affected by chronic stress, show altered gene profiles that may play a role in these changes, especially in the nucleus accumbens (NAc).
  • The study found that a specific astrocyte-produced protease gene is downregulated in males and upregulated in females, revealing sex-specific responses to stress and offering potential new targets for MDD treatment.

In Senegal, cervical cancer is the most common cancer among women and the leading cause of morbidity and mortality from all cancers. In 2018, Senegal launched a national human papillomavirus (HPV) vaccination program with Gavi, the Vaccine Alliance (Gavi), support. HPV vaccination was incorporated into the national immunization program as a two-dose schedule, with a 6-12-month interval, to nine-year-old girls via routine immunization (RI) services at health facilities, schools and community outreach services throughout the year.

Background: After a pilot project in 2014-15 Zimbabwe introduced the human papillomavirus (HPV) vaccine nationally in 2018 for girls aged 10-14 years through a primarily school-based vaccination campaign with two doses administered at 12-month intervals. In 2019, a first dose was delivered to a new cohort of girls in grade 5 of girls age 10 years if out-of-school (OOS), along with a second dose to the 2018 multiple cohorts. Additional effort was made to identify and mobilize OOS girls by Village Health Workers (VHWs) in the community.

We compared case definitions for suspected, probable, and confirmed coronavirus disease (COVID-19), as well as diagnostic testing criteria, used in the 25 countries with the highest reported case counts as of October 1, 2020. Of the identified countries, 56% followed World Health Organization (WHO) recommendations for using a combination of clinical and epidemiologic criteria as part of the suspected case definition. A total of 75% of identified countries followed WHO recommendations on using clinical, epidemiologic, and diagnostic criteria for probable cases; 72% followed WHO recommendations to use PCR testing to confirm COVID-19.

Following successful school-based demonstration programs in 2014-2016, the human papillomavirus (HPV) vaccine was introduced nationwide in Senegal for 9-year-old girls in 2018, using a routine service delivery strategy at health facilities, schools, and other outreach sites. We reviewed the HPV vaccine introduction in Senegal to understand the successes, challenges, and lessons learned. Focusing on three key domains (program decision-making, planning, and implementation), we conducted ten semi-structured interviews during 2019-2020 with purposively selected national-level stakeholders (government, expert advisory committee, key technical and implementation partners) and comprehensive desk reviews of country documents on HPV vaccine introduction.
