Changing patterns in the distribution of the Mayaro virus vector Haemagogus species in Trinidad, West Indies. Acta Trop. 2019 Jul 25;:105108 Authors: Ali R, Mohammed A, Jayaraman J, Nandram N, Feng RS, Lezcano RD, Seeramsingh R, Daniel B, Lovin DD, Severson DW, Ramsubhag A Abstract The Mayaro virus disease (MAYVD) is an emerging mosquito borne zoonosis that was first reported on the island of Trinidad in 1954. The viral agent for this disease is known to presently be endemic to Central and South America. The enzootic cycle of the Mayaro virus (MAYV) is not fully characterized, though primates are thought to be the main reservoir with Haemagogus species of mosquitoes as the primary vector. This virus has been responsible for several sporadic cases of infections and limited outbreaks, but it is postulated that the MAYVD will become a major epidemic in the future, following in the steps of the recent pandemics caused by Chikungunya and Zika viruses. Mitigating possible major outbreaks of MAYVD in the future would require effective strategies for vector control, for which knowledge on the ecology and distribution of the Haemagogus mosquitoes would be vitally important. In Trinidad, Haemagogus species have only been reported in the northwestern peninsula of the island based on studies up to 1995. However, no recent investigations have been completed to determine the status of this important vector on the island. The aim of this study was to investigate the cu...

Authors: Riskin A, Itzchaki O, Bader D, Iofe A, Toropine A, Riskin-Mashiah S Abstract BACKGROUND: The incidence of gestational diabetes mellitus (GDM) is increasing in parallel to the worldwide obesity and type 2 diabetes pandemic. Both GDM and pre-gestational diabetes mellitus (PGDM) are associated with short- and long-term consequences in the offspring. There are few recent studies addressing outcomes of newborns born to women diagnosed with GDM and PGDM in Israel. OBJECTIVES: To assess perinatal complications in offspring of women with GDM and PGDM. METHODS: The authors conducted a single-center retrospe...

CONCLUSIONS: The medical facility experienced a major decline in all aspects of the routine obstetrics activities during the time of the pandemic. The higher rate of operative vaginal deliveries among nulliparous may be associated with the pandemic effect on the rate of high-risk patients. PMID: 32954690 [PubMed - in process]

Authors: Werthmann PG, Riley D, Kienle GS Abstract Coronavirus disease 2019 (COVID-19) is a new, rapidly spreading pandemic that can lead to a life-threatening disease. Accurate and transparent COVID-19 case reports provide systematic clinical observations supporting researchers designing clinical trials and clinicians delivering health care. The checklist described here is designed to systematically and accurately capture data from case reports and case series for documentation on COVID-19. It is aligned with the CARE guidelines, available from the EQUATOR (Enhancing the QUAlity and Transparency Of health Research...
