Genetic variation in Neotropical butterflies is associated with sampling scale, species distributions, and historical forest dynamics.

Mol Ecol Resour 2021 Jun 7. Epub 2021 Jun 7.

Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" (MACN-CONICET), Buenos Aires, Argentina.

Prior studies of butterfly diversification in the Neotropics have focused on Amazonia and the tropical Andes, while southern regions of the continent have received little attention. To address the gap in knowledge about the Lepidoptera of temperate South America, we analyzed over 3,000 specimens representing nearly 500 species from Argentina for a segment of the mitochondrial COI gene. Representing 42% of the country's butterfly fauna, collections targeted species from the Atlantic and Andean forests, biodiversity hotspots that were previously connected but are now isolated.

Health Disparities in Rheumatic Diseases: Understanding Global Challenges in Africa, Europe, Latin America, and Asia and Proposing Strategies for Improvement.

Rheum Dis Clin North Am 2021 Feb;47(1):119-132

Shanghai Institute of Rheumatology, Renji Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Rheumatic diseases reach across continents with some similarities as well as unique challenges. The intersection between genetic factors, environmental exposures and socioeconomic factors, as well as challenges, with delays in access to subspecialty care and medications, manifest in different ways. By understanding both the challenges and successes in different countries, while also recognizing the significant diversity both within and across continents, unified strategies to improve rheumatic disease outcomes and decrease disparities among the most vulnerable groups can be developed and disseminated.

PLoS One 2021 19;16(5):e0251263. Epub 2021 May 19.

The Ministry of Environment, Water and Agriculture (MEWA), Jazan Veterinary Diagnostic Laboratory, Jizan, Kingdom of Saudi Arabia.

Rift Valley fever virus (RVFV), an arbovirus belonging to the Phlebovirus genus of the Phenuiviridae family, causes the zoonotic and mosquito-borne RVF. The virus, which primarily affects livestock (ruminants and camels) and humans, is at the origin of recent major outbreaks across the African continent (Mauritania, Libya, Sudan), and in the South-Western Indian Ocean (SWIO) islands (Mayotte). In order to be better prepared for upcoming outbreaks, to predict its introduction in RVFV unscathed countries, and to run efficient surveillance programmes, the priority is harmonising and improving the diagnostic capacity of endemic countries and/or countries considered to be at risk of RVF.

Catalan Institute for Water Research (ICRA). Carrer Emili Grahit 101, 17003 Girona, Spain; University of Girona. Plaça de Sant Domènec 3, 17004 Girona, Spain. Electronic address:

Impacts from urban wastewater treatment plants (WWTP) to receiving riverine surface water bodies (SWBs) depend on the load of contaminants discharged, as well as on their dilution capacity. Yet, climate change impacts on such dilution capacity and ultimately on the SWBs ecological status remain unclear. Here, we assess SWBs dilution capacity across the European continent to identify most vulnerable areas using information from centralized European databases. Read More

Front Pharmacol 2021 26;12:596855. Epub 2021 Apr 26.

Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Ibadan, Ibadan, Nigeria.

The coronavirus disease 2019 (COVID-19) pandemic is caused by an infectious novel strain of coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which was earlier referred to as 2019-nCoV. The respiratory disease is the most consequential global public health crisis of the 21st century whose level of negative impact increasingly experienced globally has not been recorded since World War II. Up till now, there has been no specific globally authorized antiviral drug, vaccines, supplement or herbal remedy available for the treatment of this lethal disease except preventive measures, supportive care and non-specific treatment options adopted in different countries via divergent approaches to halt the pandemic.

Department of Zoology, PO Box 524, Auckland Park, University of Johannesburg, 2006, South Africa. Electronic address:

The burden of the human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS) infection has transformed the African continent into a major consumer of antiretrovirals (ARVs) drugs. In addition to HIV burden, the African continent has also a high incidence of tuberculosis (TB) and has been experiencing recurring outbreaks of several other viral, bacterial, and parasitic epidemic diseases. The novel severe acute respiratory syndrome coronavirus 2 (SARS-COV-2 or Covid-19) pandemic outbreak is adding to the continent's infectious diseases burden as experts are predicting that it will be here for a long time.

Dioctophimosis: A Parasitic Zoonosis of Public Health Importance.

Adv Exp Med Biol 2021 ;1306:129-142

Project Dioctophyme renale in Dogs and Cats (PRODIC), Department of Veterinary Clinics, Veterinary College, Federal University of Pelotas, Pelotas, RS, Brazil.

Dioctophyme renale, the giant kidney worm, is a renal nematode from domestic and wild mammals that has zoonotic potential. In humans, dioctophimosis has been reported in several countries, mainly on the Asian continent, totaling more than 40 cases, which describe the parasite mainly infecting the kidneys, bladder, urethra and skin. Infection in animals and humans is related to the ingestion of the infective larva (L3) present in the aquatic oligochaete annelid (mandatory intermediate host) or fish and anurans (facultative paratenic hosts).
