A proposed one-stop-shop approach for the delivery of integrated oral, mental, sexual and reproductive healthcare to adolescents in Nigeria.

Pan Afr Med J 2020 21;37:172. Epub 2020 Oct 21.

Department of Mental Health, Obafemi Awolowo University, Ile-Ife, Osun State, Nigeria.

The interconnectedness of oral, mental, sexual, and reproductive health (OMSRH) in adolescents prompts exploration of novel approaches to facilitate comprehensive access of this population to the relevant health services. This paper proposes an integrated one-stop-shop approach to increasing adolescents' access to OMSRH care by leveraging on dental clinics as a template for integration, using a non-stigmatized platform to deliver stigmatized healthcare. Novel healthcare delivery models are needed to enhance adolescents' access to the comprehensive prevention and treatment services that they critically need. Read More

Addressing disparities and challenges in underserved patient populations with metastatic breast cancer in Europe.

Breast 2021 Feb 13;55:79-90. Epub 2020 Dec 13.

ABC Global Alliance, C/o Champalimaud Foundation, Av. Brasília, Lisbon, 1400-038, Portugal; Breast Unit, Champalimaud Clinical Center/Champalimaud Foundation, Lisbon, Portugal. Electronic address:

People with metastatic breast cancer face many challenges and disparities in obtaining optimal cancer care. These challenges are accentuated in underserved patient populations across Europe, who are less likely to receive quality healthcare for reasons including socioeconomic inequalities, educational or cultural status, or geographic location. While there are many local and national initiatives targeted to address these challenges, there remains a need to reduce disparities and improve access to healthcare to improve outcomes, with a focus on multidisciplinary stakeholder engagement.

Adaptive selection drives TRPP3 loss-of-function in an Ethiopian population.

Sci Rep 2020 12 2;10(1):20999. Epub 2020 Dec 2.

Laboratory of Molecular Physiology, Department of Experimental and Health Sciences, Universitat Pompeu Fabra, 08003, Barcelona, Spain.

TRPP3 (also called PKD2L1) is a nonselective, cation-permeable channel activated by multiple stimuli, including extracellular pH changes. TRPP3 had been considered a candidate for sour sensor in humans, due to its high expression in a subset of tongue receptor cells detecting sour, along with its membership to the TRP channel family known to function as sensory receptors. Here, we describe the functional consequences of two non-synonymous genetic variants (R278Q and R378W) found to be under strong positive selection in an Ethiopian population, the Gumuz. Read More

Lockdown measures in response to COVID-19 in nine sub-Saharan African countries.

BMJ Glob Health 2020 10;5(10)

Institute of Population Health Sciences, Barts and London Medical and Dental School, Queen Mary University of London, London, UK

Lockdown measures have been introduced worldwide to contain the transmission of COVID-19. However, the term 'lockdown' is not well-defined. Indeed, WHO's reference to 'so-called lockdown measures' indicates the absence of a clear and universally accepted definition of the term 'lockdown'. Read More

Investigating the demographic history of Japan using ancient oral microbiota.

Philos Trans R Soc Lond B Biol Sci 2020 11 5;375(1812):20190578. Epub 2020 Oct 5.

Australian Centre for Ancient DNA, University of Adelaide, Adelaide, Australia.

While microbial communities in the human body (microbiota) are now commonly associated with health and disease in industrialised populations, we know very little about how these communities co-evolved and changed with humans throughout history and deep prehistory. We can now examine these communities by sequencing ancient DNA preserved within calcified dental plaque (calculus), providing insights into the origins of disease and their links to human history. Here, we examine ancient DNA preserved within dental calculus samples and their associations with two major cultural periods in Japan: the Jomon period hunter-gatherers approximately 3000 years before present (BP) and the Edo period agriculturalists 400-150 BP.

Indoor radon exposure and excess of lung cancer mortality: the case of Mexico-an ecological study.

Environ Geochem Health 2021 Jan 24;43(1):221-234. Epub 2020 Aug 24.

SNI, Sistema Nacional de Investigadores, Mexico, Mexico.

Radon is a radioactive gas that can migrate from soils and rocks and accumulate in indoor areas such as dwellings and buildings. Many studies have shown a strong association between the exposure to radon, and its decay products, and lung cancer (LC), particularly in miners. In Mexico, according to published surveys, there is evidence of radon exposure in large groups of the population, nevertheless, only few attention has been paid to its association as a risk factor for LC.
