TL;DR: Although the BBB barrier prevents most drugs from reaching their targets, molecular vectors such as peptide shuttles offer great promise to safely overcome this formidable obstacle as mentioned in this paper and have received growing attention because of their lower cost, reduced immunogenicity, and higher chemical versatility than traditional Trojan horse antibodies and other proteins.
Abstract: Brain delivery is one of the major challenges in drug development because of the high number of patients suffering from neural diseases and the low efficiency of the treatments available. Although the blood–brain barrier (BBB) prevents most drugs from reaching their targets, molecular vectors – known as BBB shuttles – offer great promise to safely overcome this formidable obstacle. In recent years, peptide shuttles have received growing attention because of their lower cost, reduced immunogenicity, and higher chemical versatility than traditional Trojan horse antibodies and other proteins.

TL;DR: A minimum FECR rate of 95% for A. lumbricoides, 70% for hookworm, and 50% for T. trichiura is expected in MEB-dependent PC programs, which may indicate the development of potential drug resistance.
Abstract: Background: The three major soil-transmitted helminths (STH) Ascaris lumbricoides, Trichuris trichiura andNecator americanus/Ancylostoma duodenale are among the most widespread parasites worldwide. Despite the global expansion of preventive anthelmintic treatment, standard operating procedures to monitor anthelmintic drug efficacy are lacking. The objective of this study, therefore, was to define the efficacy of a single 400 milligram dose of albendazole (ALB) against these three STH using a standardized protocol. Methodology/Principal Findings : Seven trials were undertaken among school children in Brazil, Cameroon, Cambodia, Ethiopia, India, Tanzania and Vietnam. Efficacy was assessed by the Cure Rate (CR) and the Fecal Egg Count Reduction (FECR) using the McMaster egg counting technique to determine fecal egg counts (FEC). Overall, the highest CRs were observed for A. lumbricoides (98.2%) followed by hookworms (87.8%) and T. trichiura (46.6%). There was considerable variation in the CR for the three parasites across trials (country), by age or the pre-intervention FEC (pre-treatment). The latter is probably the most important as it had a considerable effect on the CR of all three STH. Therapeutic efficacies, as reflected by the FECRs, were very high for A. lumbricoides (99.5%) and hookworms (94.8%) but significantly lower for T. trichiura (50.8%), and were affected to different extents among the 3 species by the pre-intervention FEC counts and trial (country), but not by sex or age. Conclusions/Significance: Our findings suggest that a FECR (based on arithmetic means) of >95% for A. lumbricoidesand >90% for hookworms should be the expected minimum in all future surveys, and that therapeutic efficacy below this level following a single dose of ALB should be viewed with concern in light of potential drug resistance. A standard threshold for efficacy against T. trichiura has yet to be established, as a single-dose of ALB is unlikely to be satisfactory for this parasite.

TL;DR: The development of antiepileptic drugs urgently needs to be revitalized so that the authors can discover more effective antiseizure drugs for the treatment of drug resistant epilepsy, including catastrophic forms.
Abstract: Epilepsy is a serious, potentially life shortening brain disorder, the symptoms of which can be successfully treated in most patients with one or more antiepileptic drug. About two in three adults with new onset epilepsy will achieve lasting seizure remission on or off these drugs, although around half will experience mild to moderately severe adverse effects. Patients with epilepsy, especially the 20-30% whose seizures are not fully controlled with available drugs (drug resistant epilepsy), have a significantly increased risk of death, as well as psychiatric and somatic comorbidities, and adverse effects from antiepileptic drugs. Newer drugs have brought more treatment options, and some such as levetiracetam cause fewer drug interactions and less hypersensitivity than older ones. However, they do not reduce the prevalence of drug resistant epilepsy or prevent the development of epilepsy in patients at high risk, such as those with a traumatic brain injury. The development of antiepileptic drugs urgently needs to be revitalized so that we can discover more effective antiseizure drugs for the treatment of drug resistant epilepsy, including catastrophic forms. Antiepileptogenic agents to prevent epilepsy before the first seizure in at risk patients and disease modifying agents to control ongoing severe epilepsy associated with progressive underlying disease are also needed.

TL;DR: Almost one in ten adults in Bangladesh was found to have diabetes, which has recently become a major public health issue, and urgent action is needed to counter the rise in diabetes through better detection, awareness, prevention and treatment.
Abstract: Objective To estimate the prevalence of diabetes and prediabetes in Bangladesh using national survey data and to identify risk factors Methods Sociodemographic and anthropometric data and data on blood pressure and blood glucose levels were obtained for 7541 adults aged 35 years or more from the biomarker sample of the 2011 Bangladesh Demographic and Health Survey (DHS), which was a nationally representative survey with a stratified, multistage, cluster sampling design Risk factors for diabetes and prediabetes were identified using multilevel logistic regression models, with adjustment for clustering within households and communities Findings The overall age-adjusted prevalence of diabetes and prediabetes was 97% and 224%, respectively Among urban residents, the age-adjusted prevalence of diabetes was 152% compared with 83% among rural residents In total, 560% of diabetics were not aware they had the condition and only 395% were receiving treatment regularly The likelihood of diabetes in individuals aged 55 to 59 years was almost double that in those aged 35 to 39 years Study participants from the richest households were more likely to have diabetes than those from the poorest In addition, the likelihood of diabetes was also significantly associated with educational level, body weight and the presence of hypertension The prevalence of diabetes varied significantly with region of residence Conclusion Almost one in ten adults in Bangladesh was found to have diabetes, which has recently become a major public health issue Urgent action is needed to counter the rise in diabetes through better detection, awareness, prevention and treatment

TL;DR: Stable and protective childhoods are critical factors in the development of resilience to health-harming behaviors in England, with nurturing childhoods supporting the adoption of health-benefiting behaviors and the provision of positive childhood environments for future generations.
Abstract: Background: Epidemiological and biomedical evidence link adverse childhood experiences (ACEs) with health-harming behaviors and the development of non-communicable disease in adults. Investment in interventions to improve early life experiences requires empirical evidence on levels of childhood adversity and the proportion of HHBs potentially avoided should such adversity be addressed. Methods: A nationally representative survey of English residents aged 18 to 69 (n = 3,885) was undertaken during the period April to July 2013. Individuals were categorized according to the number of ACEs experienced. Modeling identified the proportions of HHBs (early sexual initiation, unintended teenage pregnancy, smoking, binge drinking, drug use, violence victimization, violence perpetration, incarceration, poor diet, low levels of physical exercise) independently associated with ACEs at national population levels. Results: Almost half (47%) of individuals experienced at least one of the nine ACEs. Prevalence of childhood sexual, physical, and verbal abuse was 6.3%, 14.8%, and 18.2% respectively (population-adjusted). After correcting for sociodemographics, ACE counts predicted all HHBs, e.g. (0 versus 4+ ACEs, adjusted odds ratios (95% confidence intervals)): smoking 3.29 (2.54 to 4.27); violence perpetration 7.71 (4.90 to 12.14); unintended teenage pregnancy 5.86 (3.93 to 8.74). Modeling suggested that 11.9% of binge drinking, 13.6% of poor diet, 22.7% of smoking, 52.0% of violence perpetration, 58.7% of heroin/crack cocaine use, and 37.6% of unintended teenage pregnancy prevalence nationally could be attributed to ACEs. Conclusions: Stable and protective childhoods are critical factors in the development of resilience to health-harming behaviors in England. Interventions to reduce ACEs are available and sustainable, with nurturing childhoods supporting the adoption of health-benefiting behaviors and ultimately the provision of positive childhood environments for future generations.

TL;DR: This is the first in a planned series of 10 volumes that will attempt to "summarize epidemiological knowledge about all major conditions and most risk factors" and use historical trends in main determinants to project mortality and disease burden forward to 2020.
Abstract: This is the first in a planned series of 10 volumes that will attempt to "summarize epidemiological knowledge about all major conditions and most risk factors;...generate assessments of numbers of deaths by cause that are consistent with the total numbers of deaths by age sex and region provided by demographers;...provide methodologies for and assessments of aggregate disease burden that combine--into the Disability-Adjusted Life Year or DALY measure--burden from premature mortality with that from living with disability; and...use historical trends in main determinants to project mortality and disease burden forward to 2020." This first volume includes chapters summarizing results from the project as a whole. (EXCERPT)
