Integrating Biological Early Warning Systems with High-Resolution Online Chemical Monitoring in Wastewater Treatment Plants.

Detection of micropollutants (MPs) in wastewater effluents using traditional toxicity tests or chemical analysis with discrete samples is challenging due to concentration dynamics. This study evaluates a continuous monitoring approach for detecting MPs in wastewater effluents using a combination of biological early warning systems (BEWS). Three BEWS with , , and were operated in parallel in a full-scale municipal wastewater treatment plant.

Application of biological early warning systems in wastewater treatment plants: Introducing a promising approach to monitor changing wastewater composition.

Wastewater treatment plants (WWTPs) are a major source of micropollutants to surface waters. Currently, their chemical or biological monitoring is realized by using grab or composite samples, which provides only snapshots of the current wastewater composition. Especially in WWTPs with industrial input, the wastewater composition can be highly variable and a continuous assessment would be advantageous, but very labor and cost intensive.

Health Information From Web Search Engines and Virtual Assistants About Pre-Exposure Prophylaxis for HIV Prevention in Adolescents and Young Adults: Content Analysis.

Background: Adolescents and young adults are disproportionately affected by HIV, suggesting that HIV prevention methods such as pre-exposure prophylaxis (PrEP) should focus on this group as a priority. As digital natives, youth likely turn to internet resources regarding health topics they may not feel comfortable discussing with their medical providers. To optimize informed decision-making by adolescents and young adults most impacted by HIV, the information from internet searches should be educational, accurate, and readable.

Adolescent Perceptions of Menstruation on Twitter: Opportunities for Advocacy and Education.

Purpose: While some adolescents celebrate menstruation as a rite of passage, others seek discretion due to stigma. Many youth have used Twitter to combat stigma and raise awareness about other culturally taboo topics, but previous work has not explored youth conversations regarding menstruation. This study aims to assess whether Twitter can provide useful insights into how youth perceive menstruation.

Evaluation of a full-scale wastewater treatment plant with ozonation and different post-treatments using a broad range of in vitro and in vivo bioassays.

Micropollutants present in the effluent of wastewater treatment plants (WWTPs) after biological treatment are largely eliminated by effective advanced technologies such as ozonation. Discharge of contaminants into freshwater ecosystems can thus be minimized, while simultaneously protecting drinking water resources. However, ozonation can lead to reactive and potentially toxic transformation products.

Fertility Desires of Adolescent Females: Decreased Desire for Children in Those Identifying as Transgender/Gender Diverse and in Depressed Adolescents.

Study Objective: We aimed to describe fertility desires in healthy adolescent females and to explore associations of fertility desire with conditions and therapies potentially compromising fertility.

Design: This was a cross-sectional, anonymous survey.

Setting And Participants: A total of 323 female adolescents aged 13-19 years were recruited from clinic waiting areas at a children's hospital.

The Reproductive Health Care of Transgender Young People: A Guide for Primary Care Providers.

Primary care providers should have a general understanding of the medical care available to transgender youth throughout childhood and adolescence. Providers and parents should create an affirming environment for young people at every developmental stage, while ensuring thorough and thoughtful evaluations prior to any medical intervention. Transgender teens have unique reproductive health care needs.

Impact of Percutaneous Drainage on Outcome of Intra-abdominal Infection Associated With Pediatric Perforated Appendicitis.

Background: Perforated appendicitis can result in potentially serious complications requiring prolonged medical care. The optimal approach to successfully managing this condition is controversial.

Methods: Review of 80 consecutive cases of pediatric acute perforated appendicitis with intra-abdominal infection (IAI) medically managed with parenteral antibiotics and percutaneous drainage (PD) during a 7-year period.

Cholecystectomy in the very elderly--is 90 the new 70?

Background: Nonagenarians are the fastest growing sector of population across Western Europe. Although prevalence of gallstone disease is high, elective cholecystectomy is still controversial in this age group.

Methods: A retrospective chart review was conducted of cholecystectomies done in patients over 90 years of age at our institution between 2004 and December 2009.
