Wastewaters contain complex mixtures of chemicals, which can cause adverse toxic effects in the receiving environment. In the present study, the toxicity removal during wastewater treatment at seven municipal wastewater treatment plants (WWTPs) was investigated using an effect-based approach. A battery of eight bioassays was applied comprising of cytotoxicity, genotoxicity, endocrine disruption and fish embryo toxicity assays. Human cell-based CALUX assays, transgenic larval models and the fish embryo toxicity test were particularly sensitive to WWTP effluents...

In the last few years, stakeholders in the scientific community have raised alarms about a perceived lack of reproducibility of scientific results. In reaction, guidelines for journals have been promulgated and grant applicants have been asked to address the rigor and reproducibility of their proposed projects. Neither solution addresses a primary culprit, which is the culture of null hypothesis significance testing that dominates statistical analysis and inference. In an innovative research enterprise, selection of results for further evaluation based on null hypothesis significance testing is doomed to yield a low proportion of reproducible results and a high proportion of effects that are initially overestimated...

Infertility affects a remarkable one in four couples in developing countries. Psychological stress is a ubiquitous facet of life, and while stress affects us all at some point, prolonged or unmanageable stress may become harmful for some individuals, negatively impacting on their health, including fertility. For instance, women who struggle to conceive are twice as likely to suffer from emotional distress than fertile women. Assisted reproductive technology treatments place an additional physical, emotional and financial burden of stress, particularly on women, who are often exposed to invasive techniques associated with treatment...

The psychologic stress on the child and family, which arise from hemangiomas, the most common neoplasm of childhood, cannot be overestimated. This study determined the preoperative and postoperative psychosocial status and variation among Oriental children with hemangiomas and their families by questionnaire. Thirty patients who underwent surgery for hemangiomas were assessed for preoperative and postoperative psychosocial status by questionnaire. The distribution of the total mean score and variation between the preoperative and postoperative status was estimated...

Interpretation of mammography for breast cancer (BC) screening can confer a mortality benefit through early BC detection, can miss a cancer that is present or fast growing, or can result in false-positives. Efforts to improve screening outcomes have mostly focused on intensifying imaging practices (double instead of single-reading, more frequent screens, or supplemental imaging) that may add substantial resource expenditures and harms associated with population screening. Less attention has been given to making mammography screening practice 'smarter' or more efficient...

INTRODUCTION: Changes to the U.S. smokeless tobacco landscape in recent years include a change to health warnings on packages, the implementation of bans in some stadiums, and the launch of a federal youth prevention campaign. It is unclear whether such changes have impacted consumer beliefs about smokeless tobacco. This study examines relative harm perceptions of smokeless tobacco compared to cigarettes among adults and assesses changes in smokeless tobacco harm perceptions over time...

INTRODUCTION: Understanding the concept of a standard drink (SD) is foundational knowledge to many public health policies aimed at reducing alcohol-related harms. These policies include adhering to low-risk drinking guidelines, screening brief intervention and referral activities, and counter alcohol-impaired driving initiatives. A lack of awareness of SDs might preclude the effectiveness of these interventions. A systematic review was conducted to review the evidence about how effective alcohol labels are in communicating SD information to the consumer...

Imaging studies are important adjuncts in the diagnostic evaluation of acute and chronic conditions. However, confusion about the safety of these modalities for pregnant and lactating women and their infants often results in unnecessary avoidance of useful diagnostic tests or the unnecessary interruption of breastfeeding. Ultrasonography and magnetic resonance imaging are not associated with risk and are the imaging techniques of choice for the pregnant patient, but they should be used prudently and only when use is expected to answer a relevant clinical question or otherwise provide medical benefit to the patient...

Brain-computer interfaces (BCIs) can enable communication for persons in severe paralysis including locked-in syndrome (LIS); that is, being unable to move or speak while aware. In cases of complete loss of muscle control, termed "complete locked-in syndrome," a BCI may be the only viable solution to restore communication. However, a widespread ignorance regarding quality of life in LIS, current BCIs, and their potential as an assistive technology for persons in LIS, needlessly causes a harmful situation for this cohort...

Nanoparticles (NPs) are part of our daily life, having a wide range of applications in engineering, physics, chemistry, and biomedicine. However, there are serious concerns regarding the harmful effects that NPs can cause to the different biological systems and their ecosystems. Toxicity testing is an essential step for assessing the potential risks of the NPs, but the experimental assays are often very expensive and usually too slow to flag the number of NPs that may cause adverse effects. In silico models centered on quantitative structure-activity/toxicity relationships (QSAR/QSTR) are alternative tools that have become valuable supports to risk assessment, rationalizing the search for safer NPs...

Nitric oxide (NO) is an important endogenous neurotransmitter and mediator. It participates in regulation of physiological processes in different organ systems including airways. Therefore, it is important to clarify its role in the regulation of both airway and vascular smooth muscle, neurotransmission and neurotoxicity, mucus transport, lung development and in the. surfactant production. The bioactivity of NO is highly variable and depends on many factors: the presence and activity of NO-producing enzymes, activity of competitive enzymes (e...

With the advancement of diagnostic tests, the call for an ever-earlier diagnosis of people with memory problems is becoming louder. Diagnostic tests for people with mild cognitive impairment are in fact prognostic tests, complicating the application and interpretation of test results. There is currently insufficient evidence on the incremental diagnostic (or prognostic) value of specific diagnostic tests including MRI, CSF and PET scanning in representative memory clinic populations. Labelling large groups of people who may never develop dementia as having prodromal Alzheimer's disease may be more harmful than a postponed nosological diagnosis in those with mild cognitive impairment...

Introduction Studies have shown that electronic cigarettes have gained immense popularity and their use has increased dramatically all over the world. However, little is known about the knowledge and attitudes towards e-cigarettes in third world countries such as Pakistan. The aim of this study was to determine the perceptions of teenagers in Karachi regarding e-cigarettes and whether the differences in said perceptions were affected by gender and level of education. Methods We conducted a cross-sectional study in January 2017 using convenience sampling and interviewed 441 young individuals, aged 13 to 19 years, to determine their knowledge, attitudes, and practices regarding e-cigarettes...

INTRODUCTION: Alcohol use is a widely prevalent problem and poses hazard during work for certain groups such as fishermen. Disorders such as Attention-Deficit/Hyperkinetic Disorder (ADHD) correlate with early onset and greater severity of alcohol use disorders. AIMS: We planned to study the frequency of ADHD among fishermen in a fishing hamlet of southern India using adult ADHD self-reported scale (ASRS) and correlated with the severity of alcohol use disorder as evidenced by age at initiation of alcohol use, presence of harmful use, or dependence use as defined by Alcohol Use Disorders Identification Test (AUDIT)...

BACKGROUND: Methods to identify preventable adverse events typically have low yield and efficiency. We refined the methods of Institute of Healthcare Improvement's Global Trigger Tool (GTT) application and leveraged electronic health record (EHR) data to improve detection of preventable adverse events, including diagnostic errors. METHODS: We queried the EHR data repository of a large health system to identify an 'index hospitalization' associated with care escalation (defined as transfer to the intensive care unit (ICU) or initiation of rapid response team (RRT) within 15 days of admission) between March 2010 and August 2015...
