Sexual communication is a principal means of transmitting sexual values, expectations, and knowledge from parents to their children and adolescents. Many parents seek information and guidance to support talking with their children about sex and sexuality. Parent education materials can deliver this guidance but must use appropriate readability levels to facilitate comprehension and motivation. This study appraised the readability of educational materials to support parent sexual communication with their children. Fifty brochures, pamphlets, and booklets were analyzed using the Flesch-Kincaid, Gunning Fog, and Simple Measure of Gobbledygook (SMOG) index methods. Mean readability grade-level scores were 8.3 (range = 4.5-12.8), 9.7 (range = 5.5-14.9), and 10.1 (range = 6.7-13.9), respectively. Informed by National Institutes of Health-recommended 6th to 7th grade levels and American Medical Association-recommended 5th to 6th grade levels, percentages falling at or below the 7.0 grade level were calculated as 38%, 12%, and 2% and those falling at or below the 6.0 grade level were calculated as 12%, 2%, and 0% based on the Flesch-Kincaid, Gunning Fog, and SMOG methods, respectively. These analyses indicate that the majority of educational materials available online to support parents' communication with their children about sex and sexuality do not meet the needs of many or most parents. Efforts to improve the accessibility of these materials are warranted.

Objectives. The mortality rate of a street-recruited homeless youth cohort in the United States has not yet been reported. We examined the six-year mortality rate for a cohort of street youth recruited from San Francisco street venues in 2004. Methods. Using data collected from a longitudinal, venue-based sample of street youth 15-24 years of age, we calculated age, race, and gender-adjusted mortality rates. Results. Of a sample of 218 participants, 11 died from enrollment in 2004 to December 31, 2010. The majority of deaths were due to suicide and/or substance abuse. The death rate was 9.6 deaths per hundred thousand person-years. The age, race and gender-adjusted standardized mortality ratio was 10.6 (95% CI [5.3-18.9]). Gender specific SMRs were 16.1 (95% CI [3.3-47.1]) for females and 9.4 (95% CI [4.0-18.4]) for males. Conclusions. Street-recruited homeless youth in San Francisco experience a mortality rate in excess of ten times that of the state's general youth population. Services and programs, particularly housing, mental health and substance abuse interventions, are urgently needed to prevent premature mortality in this vulnerable population.

Living Donor Liver Transplantation (LDLT) is a valuable solution to the shortage of donor organs for patients with end-stage liver disease. However, the eligibility of obese donors for LDLT remains a subject of debate. This literature review explores global practices and perceptions of LDLT, identifies donor eligibility criteria, and discusses special considerations and ethical caveats. The review highlights the need for standardized guidelines for donor selection, considering the global distribution of Body mass index and variations in population-specific criteria. It also emphasizes the importance of non-invasive testing and pre-operative optimization of liver steatosis for select obese donors. Furthermore, the review examines the outcomes and complications associated with obese donors in LDLT. The findings of this review contribute to the ongoing discussion on the inclusion of obese donors in LDLT and provide insights for future research and guideline development. [ABSTRACT FROM AUTHOR]

Reversible interactions between DNA and silica are utilizedinthe solid phase extraction and purification of DNA from complex samples.Chaotropic salts commonly drive DNA binding to silica but inhibitDNA polymerase amplification. We studied DNA adsorption to silicausing conditions with or without chaotropic salts through bulk depletionand quartz crystal microbalance (QCM) experiments. While more DNAadsorbed to silica using chaotropic salts, certain buffer conditionswithout chaotropic salts yielded a similar amount of eluted DNA. QCMresults indicate that under stronger adsorbing conditions the adsorbedDNA layer is initially rigid but becomes viscoelastic within minutes.These results qualitatively agreed with a mathematical model for amultiphasic adsorption process. Buffer conditions that do not requirechaotropic salts can simplify protocols for nucleic acid sample preparation.Understanding how DNA adsorbs to silica can help optimize nucleicacid sample preparation for clinical diagnostic and research applications.

Background: Ulcerative Colitis (UC) is characterized by chronic, relapsing and remitting inflammation in the colon and rectum. Pathogenic T cell activity is thought to play a major role in this process. T cell effector function is determined by the T cell receptor (TCR) and the antigen it recognizes. Examining the TCR repertoire can provide key insights into the adaptive immune response., Objective: To characterize the longitudinal TCR repertoire of patients with UC across disease activity to determine if recurrent antigen(s) are responsible for active inflammation., Design: Bulk TCR Vβ sequencing was done on colon tissue of 20 patients with UC across multiple time points of disease. Corresponding clinical metadata was also obtained over the same time period for each patient to map their clinical disease course. The top ten most highly abundant clones from each time point were longitudinally tracked and correlated with disease phenotype., Results: Seventy-five percent of patients did not have overlapping abundant TCR clones across multiple time points of disease. The remaining 25% of patients had one to five TCR clones present in high abundance in their tissue during every time point analyzed., Conclusion: These results demonstrate that most patients with UC do not share a similar TCR repertoire over time, indicating that times of inflammation are associated with unique antigen exposures. A smaller group of patients have persistent, private TCR clones with high abundance, 60% of whom had more unremitting, active disease.

Objective: To describe the prescription of hydrocodone-containing products (HCPs) and codeine-containing products (CCPs) by patient and provider race and ethnicity at two pediatric emergency departments (EDs) before and after the US Drug Enforcement Administration (DEA) rescheduling of HCPs in 2014., Design and Setting: The authors performed a secondary analysis of data describing the prescription of HCPs and CCPs for 6 months before and after the DEA rescheduling of HCPs in two academic, urban pediatric EDs., Patients, Participants: The authors included all children for whom race and ethnicity data were available and who were prescribed HCPs or CCPs at the time of discharge from the ED during a 12-month period (n = 1,246). The authors sent a three-question survey soliciting name, race, and ethnicity to all providers who prescribed an HCP or a CCP during the study period., Main Outcome Measures: Chi-square comparisons were made between the number of HCP and CCP prescriptions for primary ED diagnosis and patient ethnicity or race. The number of HCP and CCP prescriptions before and after the DEA rescheduling were compared to patient and provider race and ethnicity using the Breslow-Day test for homogeneity., Results: There were no significant differences in the number of HCP and CCP prescriptions between the pre- and post-DEA rescheduling periods across all racial and ethnic groups. When comparing the number of HCP and CCP prescriptions to patient race, Caucasian patients (84.4 percent) were prescribed more HCPs and CCPs than African Americans (15.6 percent) for abdominal pain (p value = 0.02). Non-Hispanic providers prescribed CCPs more often (n = 38, 55.2 percent) than Hispanic providers (n = 0, 0.0 percent) after DEA rescheduling (Breslow-Day p value = 0.01). Providers of all races wrote similar numbers of HCP and CCP prescriptions before and after the DEA rescheduling (Breslow-Day p value = 0.99)., Conclusions: Pediatric patients of all races and ethnicities received fewer HCP prescriptions after the 2014 DEA rescheduling of HCPs. However, Caucasian patients were prescribed HCPs and CCPs for abdominal pain more frequently than African American patients. There were no significant differences in the number of prescriptions of HCPs and CCPs by provider race.

A 34-year-old woman with chronic sinusitis and nasal polyps was treated with bilateral pansinusotomy. Postoperatively, she had a unilateral superior oblique paresis. We suspect that superior oblique damage occurred without involvement of the medial rectus because of inadvertent entry of the endoscopic probe through the superior lamina into the left orbit., (Copyright © 2015 American Association for Pediatric Ophthalmology and Strabismus.
