Background: Breastfeeding maintains the maternal-fetal immune link after birth, favors the transmission of immunological competence, and is considered an important contributing factor to the development of the babies' immune system.

Objective: This study aimed to obtain data related to the effects of gestational diabetes on immunoglobulin A (IgA) and cytokines levels in the colostrum, before and during the pandemic of the new coronavirus, in order to study the possible outcomes regarding the immunological characteristics of human milk.

Methods: This systematic review was registered in PROSPERO CRD42020212397, and the question elaborated using the PICO strategy was: does maternal hyperglycemia associated or not with Covid-19 influence the immunological composition of colostrum? Electronic searching and reference lists of published reports were used to identify studies that reported the influence of gestational diabetes on colostrum and milk composition.

Article Synopsis
  • The study focuses on the rising issue of coinfection rates between human visceral leishmaniasis (HVL) and HIV in Brazil from 2007 to 2015, highlighting the geographic overlap of these diseases.
  • The research utilized geoprocessing tools to analyze spatial patterns and epidemiological data, revealing significant correlations and an increasing trend in HVL/HIV cases, particularly in regions like the North and Northeast, as well as states like Maranhão and Sergipe.
  • Findings emphasize the need for targeted interventions in areas with high rates of coinfection to prevent further cases, indicating a clear link between the two diseases.

American tegumentary leishmaniasis (ATL) is considered a neglected disease, for which an effective vaccine or an efficient diagnosis is not yet available and whose chemotherapeutic arsenal is threatened by the emergence of resistance by etiological agents such as Leishmania amazonensis. ATL is endemic in poor countries and has a high incidence in Brazil. Vaccines developed from native parasite fractions have led to the identification of defined antigenic subunits and the development of vaccine adjuvant technology.
