The Association Between Substance Use and Violence: Results from a Nationally Representative Sample of High School Students in the United States.

With over 52% of high school students reporting that they have tried alcohol or illicit drugs, 16% carrying a weapon, and 23% engaging in a physical fight, substance use and youth violence remain critical public health challenges in the United States. Using data from the 2017 Youth Risk Behavior Survey, study results revealed that youth who reported heavy use of either alcohol, marijuana, or illicit drugs were three to ten times more likely to report carrying a weapon or engaging in a physical fight. Similarly, youth with heavy substance use were one and half times to 14 times more likely to be a victim of violence or sexual or dating violence. The SEM analysis indicated that substance use had a significant effect on all aspects of violence. School-based behavioral health specialists and community-based pediatricians may need to develop targeted messages to address the potential for violence among youth who use alcohol and/or illicit drugs.

"All boats will rise": Physicians' perspectives on multidisciplinary lung cancer care in a community-based hospital setting.

PURPOSE: We explored the perceived strengths, barriers to implementation, and suggestions for sustainable implementation of a multidisciplinary model within a community-based hospital system from the physicians' perspectives. METHODS: We conducted 9 focus groups with 37 physicians involved in the care of lung cancer patients. Grounded theory methodology guided the identification of recurrent themes that emerged from the qualitative data analysis. RESULTS: The majority of study participants agreed that the multidisciplinary model could benefit patients by promoting high quality, efficient, and well-coordinated care. Co-location, financial disincentives, and time constraints were identified as major deterrents to full participation in a multidisciplinary clinic. Other perceived challenges were the integration of a multidisciplinary care model into the existing healthcare system, maintenance of referral streams, and designation of the physician primarily responsible for a patient's care. Educating physicians about the availability of a multidisciplinary clinic, establishing efficient processes for initial consultations, implementing technology for virtual participation, and using a nurse navigator with reliable closed-loop communication were suggested to improve the implementation of the multidisciplinary model. CONCLUSIONS: Physicians generally agreed that the multidisciplinary model could improve lung cancer care, but they perceived significant personal, institutional, and system-level barriers that need to be addressed for its successful implementation in a community healthcare setting.

Psychosocial interventions for informal caregivers of lung cancer patients: A systematic review.

OBJECTIVE: Caregivers of patients with lung cancer often face physical, emotional, and financial distress, which not only negatively affects the caregivers' mental health and quality of life but may also impact patients' well-being. The purpose of this systematic review is to examine the content, delivery, and efficacy of psychosocial interventions targeting caregivers of lung cancer patients. METHODS: Studies included in this systematic review assessed psychosocial interventions for caregivers of lung cancer patients that were published in English between January 2009 and December 2017. These interventions focused on burden, mental health, quality of life, self-efficacy, and/or coping as outcome measures. CINAHL, PubMed, PsycInfo, Science Direct, and Web of Science databases were searched using the terms (lung cancer OR lung neoplasms OR thoracic cancer) AND (caregiver OR caregiving) AND (intervention OR program) to systematically review the relevant literature on this topic. RESULTS: From the 22 studies included in this systematic review, interventions were classified into four categories: communication-based interventions, coping skills training interventions, multicomponent interventions, and stress reduction interventions. The majority of the interventions (especially communication-based and multicomponent) led to improvement, albeit not always statistically significant, in one or more outcomes; however, the most frequently reported improvements included, burden, distress, anxiety, depression, overall quality of life, self-efficacy, and coping abilities. CONCLUSIONS: The unmet needs of informal caregivers of lung cancer patients have a significant impact on their mental health and quality of life, but this burden can be alleviated by psychosocial interventions that offer appropriate support, education, and resources.

Bone Accrual in Children and Adolescent Nonelite Swimmers: A 2-Year Longitudinal Study.

OBJECTIVE: To examine differences in bone mass between children and adolescents swimming competitively at nonelite levels (locally and regionally) and nonathletes and to assess changes in bone mass in these 2 groups over 24 months after taking into consideration several known confounders of bone mass. DESIGN: Observational prospective study. PARTICIPANTS: White nonelite swimmers (n = 128) and nonathletes (n = 106) 8 to 18 years of age from Memphis, Tennessee, USA. MAIN OUTCOME MEASURES: Participants underwent dual-energy x-ray absorptiometry to assess total body and hip bone mineral content (BMC) at baseline and 12 and 24 months later. RESULTS: At baseline, swimmers had 4.2% and 6.1% higher adjusted BMC for the total body and hip, respectively, compared with nonathletes (P values < 0.027). Averaging across assessment points, swimmers had 73.5 and 2.2 g higher BMC for the total body and hip, respectively, than nonathletes. Although there was a significant annual increase in total body and hip BMC in both groups (33.5 and 0.7 g, respectively), there was no difference in annualized bone accrual between swimmers and nonathletes for either total body BMC (swim by time effect; P = 0.213) or hip BMC (P = 0.265). CONCLUSIONS: Competitive swimming at nonelite levels during childhood and adolescence does not seem to compromise bone accrual.

Comparison of nutritional intake in US adolescent swimmers and non-athletes.

Swimming is a very popular sport among adolescents in the US. Little is known about the diet of competitive adolescent swimmers in the US but data from other countries indicate several inadequacies, including excessive intake of fat and lower than recommended intake of carbohydrate and several micronutrients that may affect athletic performance and bone accrual. We assessed usual diet, using a food frequency questionnaire and calcium checklist, among 191 adolescent males and females [91 swimmers (mean 13.7, s = 2.5 years) and 100 non-athletes (mean 14.4, s = 2.8 years)]. For both males and females, swimmers and non-athletes generally had similar average intakes of macro- and micro-nutrients, including higher than recommended amounts of total fat (36%) and saturated fat (12%), and inadequate amounts of calcium, vitamin D, and daily servings of fruits, vegetables, grains, and dairy products. This first study of nutritional intake among adolescent swimmers in the US suggests that dietary habits of adolescents who swim competitively may jeopardize optimal athletic performance and place them at risk for future chronic diseases, including osteoporosis.

Complex segregation analysis of hypospadias.

Hypospadias, when the urethra opens on the ventral side of the penis, is a common malformation seen in about 3 per 1000 male births. It is considered a complex disorder with both genetic and environmental factors involved in the pathogenesis. Low birth weight is known to be an important risk factor for hypospadias, but several observations speak in favour of genetic factors as well. In order to delineate the relative contribution of the genetic factors behind hypospadias, we performed a complex segregation analysis of 2005 pedigrees in Sweden. The probands were ascertained through the departments of paediatric surgery and departments of plastic surgery and urology in Sweden where boys with hypospadias undergo surgery. In 7% of the ascertained families one or more additional cases of hypospadias were present. The complex segregation analysis showed a heritability of 0.99 and evidence for multifactorial inheritance. The results suggest that hypospadias might be due to monogenic effects in a small proportion of the families, but that there is a multifactorial cause for the majority of the cases.
