Previous publications list ten species in the Laurencia complex from South Africa with all ascribed to the genus Laurencia sensu stricto. However, the diversity of the complex in South Africa has not yet been reassessed following the numerous recent taxonomic changes. The present study investigated the phylogenetic relationships and taxonomy of this group in South Africa using recent collections. Methods included a molecular phylogenetic analysis of plastid rbcL gene sequences (a total of 146; including eleven outgroup taxa) using Bayesian Inference, and the examination of morphological and anatomical characters, including the number of corps en cerise when present...

INTRODUCTION: Lamotrigine is used in pregnancy to control epilepsy and mood disorders. The reproductive safety of this widely used drug remains undefined and may represent a significant public health concern. OBJECTIVE: We aimed to perform a systematic review and meta-analysis of existing knowledge related to malformation rates and maternal-neonatal outcomes after in utero exposure to monotherapy with lamotrigine. METHODS: Relevant studies were identified through systematic searches conducted in MEDLINE (Ovid), Embase (Ovid), CENTRAL (Ovid), and Web of Science (Thomson Reuters) from database inception to July 2016; no language or date restrictions were applied...

Hepatitis E is an emerging zoonotic infection of increasing public health threat for the UK, especially for immunosuppressed individuals. A human recombinant vaccine has been licensed only in China and is not clear whether it protects against hepatitis E virus (HEV) genotype 3, the most prevalent in Europe. The aim of this study was to use phage display technology as a tool to identify peptides that mimic epitopes of HEV capsid (mimotopes). We identified putative linear and conformational mimotopes using sera from Scottish blood donors that have the immunological imprint of past HEV infection...

On March 15, 2017 the union cabinet approved the new National Health Policy. The next day a 28-page policy text and an accompanying 13-page situational analysis were placed in Parliament and in the public domain. To have, at all times, a health policy in place that shows a road map on how a nation would show "progressive realization" of health as a basic human right is an obligation under the International Covenant on Economic, Social and Cultural Rights. This is an international treaty adopted in 1976, to which India became a signatory in 1979, and this was one of the catalysts for the adoption of the first National Health Policy in 1 983...

Substance use disorders are among the most prevalent and emergent public health problems in India. The treatment of individuals with these disorders is associated with many ethical dilemmas. Due to the pervasiveness of substance use disorders, the majority of mental health professionals working in the area of addiction medicine face several ethical dilemmas. When discussing substance use disorders, it must be borne in mind that there are important differences between India and the western countries in terms of the social and cultural aspects, as well as the legislative framework and healthcare delivery system...

Exposure to inorganic arsenic (iAs) in drinking water is a global public health concern and is associated with a range of health outcomes, including immune dysfunction. Children are a particularly sensitive population to the effects of inorganic arsenic, yet the biological mechanisms underlying adverse health outcomes are understudied. Here we used a proteomic approach to examine the effects of iAs exposure on circulating serum protein levels in a cross-sectional children's cohort in Mexico. To identify iAs-associated proteins, levels of total urinary arsenic (U-tAs) and its metabolites were determined and serum proteins assessed for differences in expression...

Maternal immunisation has the potential to substantially reduce morbidity and mortality from infectious diseases after birth. The success of tetanus, influenza, and pertussis immunisation during pregnancy has led to consideration of additional maternal immunisation strategies to prevent group B streptococcus and respiratory syncytial virus infections, among others. However, many gaps in knowledge regarding the immunobiology of maternal immunisation prevent the optimal design and application of this successful public health intervention...

Within the United States and Puerto Rico, publicly owned treatment works (POTWs) process 130.5 Gl/d (34.5 Bgal/d) of wastewater, producing sludge as a waste product. Emerging technologies offer novel waste-to-energy pathways through whole sludge conversion into biofuels. Assessing the feasibility, scalability and tradeoffs of various energy conversion pathways is difficult in the absence of highly spatially resolved estimates of sludge production. In this study, average wastewater solids concentrations and removal rates, and site specific daily average influent flow are used to estimate site specific annual sludge production on a dry weight basis for >15,000 POTWs...

Predatory open access is a controversial publishing business model that exploits the open-access system by charging publication fees in the absence of transparent editorial services. The credibility of academic publishing is now seriously threatened by predatory journals, whose articles are accorded real citations and thus contaminate the genuine scientific records of legitimate journals. This is of particular concern for public health since clinical practice relies on the findings generated by scholarly articles...

INTRODUCTION: Cytotoxic chemotherapy is the mainstay treatment for metastatic colorectal cancer (mCRC). Fluoropyrimidines, oxaliplatin, and irinotecan are the most active drugs; however, their optimal sequencing has not yet been established. Some evidence has shown that upfront treatment with 5-fluorouracil, oxaliplatin, and irinotecan (FOLFOXIRI regimen) can improve outcomes for patients with mCRC. MATERIALS AND METHODS: We performed a systematic search in electronic databases...
