Arbind Kumar Choudhary, Etheresia Pretorius
Aspartame is a synthetic dipeptide artificial sweetener, frequently used in foods, medications, and beverages, notably carbonated and powdered soft drinks. Since 1981, when aspartame was first approved by the US Food and Drug Administration, researchers have debated both its recommended safe dosage (40 mg/kg/d) and its general safety to organ systems. This review examines papers published between 2000 and 2016 on both the safe dosage and higher-than-recommended dosages and presents a concise synthesis of current trends...

Depression and musculoskeletal pain are associated, but long-term follow-up studies are rare. We aimed to examine the relationship of early depressive symptoms with developmental patterns of musculoskeletal pain from adolescence to middle age. Adolescents ending compulsory school (age 16) in Luleå, Northern Sweden, in 1981 (n = 1083) were studied and followed up in 1986, 1995, and 2008 (age 43) for musculoskeletal pain. Attrition was very low. Indicators for any and severe pain were based on pain in the neck-shoulders, low back, and the extremities...

BACKGROUND: Previous reports have shown that lung cancer incidence and mortality were increasing both in male and female; however, the temporal trends in lung cancer eliminated life expectancy and potential years of life lost (PYLL) are very rare. Thus, we examine the temporal trends in lung cancer eliminated life expectancy and PYLL in Kunshan city, Jiangsu province, 1981-2015. METHODS: Data were collected from vital registry of Kunshan city. Lung cancer eliminated life expectancy and the PYLL were calculated by sex...

BACKGROUND: Although cancer treatment considerably affects cardiovascular health, little is known about how cancer patients are treated for an acute myocardial infarction. We aimed to investigate whether acute myocardial infarction patients with a history of cancer received the same guideline recommended treatment as those acute myocardial infarction patients without and whether they differ with respect to inhospital outcome. METHODS: All patients with ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction, enrolled between 2002 and mid-2015 in the acute myocardial infarction in Switzerland (AMIS Plus) registry with comorbidity data based on the Charlson comorbidity index were analysed...

With the increase in anthropogenic environmental disruption, the behavior of arsenic in the Baltic Sea has received more scientific attention because of its complex forms and toxicity, and was re-visited to determine if there have been measurable changes recently. A cruise was conducted in 10-19 May 2011 to investigate the species and distribution of total dissolved inorganic arsenic (TDIAs: [TDIAs]=[As(V)]+[As(III)]) revealing links between the hydrographic dynamics and biological/chemical reactions in the Baltic Sea...

OBJECTIVES: The association between Holocaust experience, suicide and psychiatric hospitalization has not been unequivocally established. The aim of this study was to determine the risk of suicide among three Jewish groups with past or current psychiatric hospitalizations: Holocaust survivors (HS), survivors of pre- Holocaust persecution (early HS) and a comparison group of similar European background who did not experience Holocaust persecution. METHODS: In a retrospective cohort study based on the Israel National Psychiatric Case Register (NPCR) and the database of causes of death, all suicides in the years 1981-2009 were found for HS (n = 16,406), early HS (n = 1,212) and a comparison group (n = 4,286)...

The Integrative Psychiatric Research (iPSYCH) consortium has established a large Danish population-based Case-Cohort sample (iPSYCH2012) aimed at unravelling the genetic and environmental architecture of severe mental disorders. The iPSYCH2012 sample is nested within the entire Danish population born between 1981 and 2005, including 1 472 762 persons. This paper introduces the iPSYCH2012 sample and outlines key future research directions. Cases were identified as persons with schizophrenia (N=3540), autism (N=16 146), attention-deficit/hyperactivity disorder (N=18 726) and affective disorder (N=26 380), of which 1928 had bipolar affective disorder...

Feline immunodeficiency virus (FIV), like other retroviruses, displays large genomic divergence when different isolates are compared. In this study, 31 FIV positive samples of domestic cats from Porto Alegre, RS, Brazil were used aiming at a detailed genomic characterization and a better understanding of the molecular epidemiology of the virus in Brazil. The proviral env genes were partially amplified, sequenced and compared with another 237 sequences from different continents. We identified several Brazilian highly supported clades (A, B1, B2, C and D) that suggest independent events of introduction of FIV in Brazil...

Growing water demands put increasing pressure on local water resources, especially in water-short countries. Virtual water trade can play a key role in filling the gap between local demand and supply of water-intensive commodities. This study aims to analyse the dynamics in virtual water trade of Tunisia in relation to environmental and socio-economic factors such as GDP, irrigated land, precipitation, population and water scarcity. The water footprint of crop production is estimated using AquaCrop for six crops over the period 1981-2010...

The difference in mortality between current and never-smokers varies over time, affecting future projections of health gains from tobacco control. We examine this heterogeneity by sex, ethnicity and cause of death on absolute and relative scales using New Zealand census data. These data included smoking status, and were linked to subsequent mortality records in 1981-84, 1996-99 and 2006-11 for 25-74 year olds (16.1 million person-years of follow-up). Age-standardised mortality rates and rate differences (SRDs) were calculated comparing current to never-smokers, and Poisson regression was used to adjust for multiple socioeconomic factors and household smoking...

Objective: Several studies of sex differences in lung cancer survival have been reported. However, large-size population-based studies based on long-term observation are scarce. We investigated long-term trends in sex differences in lung cancer survival using population-based cancer registry data from Osaka, Japan. Methods: We analyzed 79 330 cases from the Osaka Cancer Registry (OCR) diagnosed between 1975 and 2007. We calculated 5-year relative survival in the six periods (1975-1980, 1981-1986, 1987-1992, 1993-1997, 1998-2002 and 2003-2007)...

PURPOSE: In the U.S., Kaposi sarcoma (KS) occurs mostly in HIV-infected patients, who are also at increased risk of developing secondary cancers. The trends in secondary cancer risk are unclear in the HAART era. METHODS: We extracted data from the SEER database on patients diagnosed with KS between 1981 and 2013, stratified into the pre-HAART (1981-1995) and HAART (1996-2013) eras. We compared the risk of secondary cancer in KS patients and the general population, and estimated the absolute risk...

INTRODUCTION: According to the 1981 International League Against Epilepsy classification, absence seizures are the paradigm of idiopathic generalised seizures of childhood. Although absences are mainly of an idiopathic origin, there are also symptomatic absences, which account for 10% of all cases of absences. It is thought that a structural pathology can favour the appearance of absences in genetically predisposed individuals. CASE REPORTS: We report the cases of two patients with symptomatic absence seizures of childhood onset...

In 1981 I established kingdom Chromista, distinguished from Plantae because of its more complex chloroplast-associated membrane topology and rigid tubular multipartite ciliary hairs. Plantae originated by converting a cyanobacterium to chloroplasts with Toc/Tic translocons; most evolved cell walls early, thereby losing phagotrophy. Chromists originated by enslaving a phagocytosed red alga, surrounding plastids by two extra membranes, placing them within the endomembrane system, necessitating novel protein import machineries...

Deepthi Rajsekhar, Steven M Gorelick
In countries where severe drought is an anticipated effect of climate change and in those that heavily depend on upstream nations for fresh water, the effect of drier conditions and consequent changes in the transboundary streamflow regime induced by anthropogenic interventions and disasters leads to uncertainty in regional water security. As a case in point, we analyze Jordan's surface water resources and agricultural water demand through 2100, considering the combined impacts of climate change and land-use change driven by the Syrian conflict...
