BACKGROUND: Associations between parenting and child outcomes are often interpreted as reflecting causal, social influences. However, such associations may be confounded by genes common to children and their biological parents. To the extent that these shared genes influence behaviours in both generations, a passive genetic mechanism may explain links between them. Here we aim to quantify the relative importance of passive genetic v. social mechanisms in the intergenerational association between parent-offspring relationship quality and offspring internalizing problems in adolescence...

OBJECTIVE: Irritable and oppositional behaviors are increasingly considered as distinct dimensions of oppositional defiant disorder. However, few studies have explored this multidimensionality across the broader spectrum of disruptive behavior problems (DBPs). This study examined the presence of dimensions and distinct subgroups of childhood DBPs, and the cross-sectional and longitudinal associations between these dimensions. METHOD: Using factor mixture models (FMMs), the presence of dimensions and subgroups of DBPs was assessed in the Generation R Study at ages 6 (n = 6,209) and 10 (n = 4,724) years...

PURPOSE: Disordered eating is more prevalent among adolescents with attention deficit/hyperactivity disorder. Both inattention and hyperactivity/impulsivity symptoms show strong associations with disordered eating, but few investigations of these associations have been longitudinal. Thus, we examined the effect of childhood to adolescent inattention and hyperactivity/impulsivity symptom trajectories on late adolescent disordered eating. METHODS: We used growth mixture modeling to identify distinct inattention and hyperactivity/impulsivity symptom trajectories (called "classes") across three time points (ages 8-9, 13-14, and 16-17 years) in the Swedish Twin study of CHild and Adolescent Development...

Open anterior repair for inguinal hernia offers several distinct advantages over endoscopic repair, especially when real-world effectiveness is taken into account. The learning curve for endoscopic techniques is long, whereas the Lichtenstein and other open tension-free techniques are easier to teach and replicate at all levels. The outcomes of Lichtenstein repairs for primary inguinal hernia as performed by non-experts and supervised residents are comparable to those of experts. Moreover, open tension-free repair does not require expensive instruments or dedicated equipment, other than the prosthetic mesh...

For centuries healing has been embedded in non-Western cultures. Traditional cultures believe that healing is derived from the divine and utilize a holistic approach to healing including the body, mind, and spirit. The community and environment are key elements in individual healing along with herbal remedies and ceremonies. Western cultures have accepted some traditional methods of relaxation and exercise, such as yoga and tai chi. In this paper we will examine some similar themes of traditional practices to better understand traditional patients' healing paradigm and find new tools as practitioners of Western medicine...

HIV disproportionately affects young Black men who have sex with men in the USA, with especially high rates in the Deep South. In this Alabama study, we interviewed 24 pairs of young Black men who have sex with men aged 19-24 and their close friends (n = 48) about sexual scripts, dating men and condom use. Three main themes emerged from the study: the power dynamics of 'top' and 'bottom' sexual positions for condom use; gender stereotyping in the iconic style of the 'I Love Lucy' show of the 1950s; and the sexual dominance of 'trade' men...

OBJECTIVE: To determine whether patients who receive an inguinal hernia repair father the same number of children as the background population. BACKGROUND: Although the effect of inguinal hernia repair on male fertility has previously been investigated through indirect measures, no previous studies have evaluated the final measure of male fertility, which is the number of children fathered by patients. METHODS: Prospectively collected data on 32,621 male patients between the ages of 18 and 55 years who received 1 or more inguinal hernia repairs during the years 1998 to 2012 were found in 5 comprehensive Danish linked registers...

OBJECTIVE: To estimate risks of neurodegenerative and psychiatric diseases among patients with amyotrophic lateral sclerosis (ALS) and their families. METHODS: We conducted a register-based nested case-control study during 1990-2013 in Sweden to assess whether patients with ALS had higher risks of other neurodegenerative and psychiatric diseases before diagnosis. We included 3,648 patients with ALS and 36,480 age-, sex-, and county of birth-matched population controls...

INTRODUCTION: Performance-based feedback is critical to surgical skills acquisition. Barriers of geography and time limit trainees' access to expert mentorship. In this study, we hypothesized that telementoring using an asynchronous, web-based video interface would allow trainees to receive systematic feedback from expert mentors despite these barriers. MATERIALS AND METHODS: Between October 2014 and October 2016, 18 surgeons in Brazil, Dominican Republic, Haiti, and Paraguay underwent in-person training in Lichtenstein for hernioplasty or laparoscopic total extraperitoneal inguinal hernia repair...

Twin studies show the established relation between bulimic symptoms and problematic alcohol involvement in adult females is partly due to shared familial factors, specifically shared genetic effects. However, it is unclear if similar shared etiological factors exist during adolescence or in males. We examined the familial overlap (i.e., genetic and common environmental correlations) between bulimic symptoms and various levels of alcohol involvement in 16- to 17-year-old female and male same-sex twin pairs using sex-specific biometrical twin modeling...

Fatty acids (FAs) are essential components of cell membranes and play an integral role in membrane fluidity. The lipophilic index [LI, defined as the sum of the products between FA levels and melting points (°C), divided by the total amount of FA: [Formula: see text]] is thought to reflect membrane and lipoprotein fluidity and may be associated with the risk of coronary heart disease (CHD). Therefore, we examined the associations of dietary and plasma phospholipid (PL) LI with CHD risk among postmenopausal women...

BACKGROUND: An incisional hernia in a case of antethoracic pedicled jejunal flap esophageal reconstruction after esophagectomy is a very rare occurrence, and this hernia was distinctive in that the reconstructed jejunum had passed through the hernial orifice; a standard surgical treatment for such a presentation has not been established. Herein, we describe a case of repair using mesh prosthesis for an atypical and distinctive incisional hernia after antethoracic pedicled jejunal flap esophageal reconstruction...

Importance: Individuals with attention-deficit/hyperactivity disorder (ADHD) are at greater risk for academic problems. Pharmacologic treatment is effective in reducing the core symptoms of ADHD, but it is unclear whether it helps to improve academic outcomes. Objective: To investigate the association between the use of ADHD medication and performance on higher education entrance tests in individuals with ADHD. Design, Setting, and Participants: This cohort study observed 61 640 individuals with a diagnosis of ADHD from January 1, 2006, to December 31, 2013...

BACKGROUND: Twin studies of hoarding symptoms indicate low to moderate heritability during adolescence and considerably higher heritability in older samples, suggesting dynamic developmental etiological effects. The aim of the current study was to estimate the relative contribution of additive genetic and environmental effects to hoarding symptoms during adolescence and young adulthood and to estimate the sources of stability and change of hoarding symptoms during adolescence. METHODS: Univariate model-fitting was conducted in three cohorts of twins aged 15 (n = 7,905), 18 (n = 2,495) and 20-28 (n = 6,218)...

School-based concussion management programs cover thousands of young athletes, yet there is little in the way of research to assess program processes or outcomes. This study examined the referral patterns of consultants working with ten high school concussion management programs. In addition to the number of referrals made to specialists, other potential outcome variables were explored. The sample included over 5,000 athlete-seasons and 298 concussions managed directly by certified athletic trainers. All programs used computerized neuropsychological testing (both baseline and post injury)...

The Bethe-Slater (BS) curve describes the relation between the exchange coupling and interatomic distance. Based on a simple argument of orbital overlaps, it successfully predicts the transition from antiferromagnetism to ferromagnetism, when traversing the 3d series. In a previous article [Phys. Rev. Lett. 116, 217202 (2016)] we reported that the dominant nearestneighbour (NN) interaction for 3d metals in the bcc structure indeed follows the BS curve, but the trends through the series showed a richer underlying physics than was initially assumed...
