Factors Influencing Adolescent Girls’ Sexual Behavior: A Secondary Analysis of the 2011 Youth Risk Behavior Survey

Adolescence is a tumultuous and challenging time period in life. Sexual risk behavior among adolescents is a widespread topic of interest in the current literature. Two common factors that influence increased sexual risk behavior are symptoms of depression and negative body image. The purpose of this study was to investigate the effect of body image and symptoms of depression upon sexual risk-taking in an adolescent female population. A secondary data analysis of the 2011 Youth Risk Behavior Survey (YRBS) was used to explore girls’ sexual activity, body image, and mental health. There were 7,708 high-school girls who participated in this study. Three questions were used to represent the constructs under investigation. There were significant correlations between sexual activity, body image, and symptoms of depression; only symptoms of depression were significant predictors of both sexual activity and condom usage. Body image was a predictor of sexual activity, but not condom use. Our findings support previous studies that suggested that people with depressive symptoms were more likely to engage in risky sexual behaviors. Our study also supports the idea that a negative body image decreases sexual activity; however, other researchers have reported that negative body image leads to an increase in sexual activity.     

Response to treatment with rosiglitazone in familial partial lipodystrophy due to a mutation in the LMNA gene

Background Familial partial lipodystrophy (FPLD) is a monogenic form of diabetes characterised by a dominantly inherited disorder of adipose tissue associated with the loss of subcutaneous fat from the limbs and trunk, with excess fat deposited around the face and neck. The lipodystrophy causes severe insulin resistance, resulting in acanthosis nigricans, diabetes, dyslipidaemia, and increased risk of cardiovascular disease. Preliminary results from animals and man suggest that increasing subcutaneous fat by treatment with thiazolidinediones should improve insulin resistance and the associated features of this syndrome. Case report We report a 24-year-old patient with FPLD caused by a mutation in the LMNA gene (R482W) treated with 12 months of rosiglitazone. Subcutaneous fat increased following rosiglitazone treatment as demonstrated by a 29% generalised increase in skin-fold thickness. Leptin levels increased from 5.8 to 11.2 ng/ml. Compared with treatment on Metformin, there was an increase in insulin sensitivity (HOMA S% 17.2–31.6) but no change in glycaemic control. The lipid profile worsened during the follow-up period. Conclusion This initial case suggests that, for modification of cardiovascular risk factors, there are no clear advantages in treating patients with FPLD with rosiglitazone despite increases in subcutaneous adipose tissue. Larger series will be needed to identify moderate beneficial effects and treatment may be more effective in patients with generalised forms of lipodystrophy.     

Issues surrounding chiropractic fee negotiations in Saskatchewan

Chiropractic fee negotiations in Saskatchewan utilize the Chiropractic Compensation Review Committee with recourse to the Chiropractic Consultation Committee. Health care professionals who practise on a fee for service basis provide the government with a budgetary problem. Although the fees are set, the health care provider can determine his own income by deciding how many visit services he/she wishes to provide. In the fiscal years 1981-82 to 1990-91, chiropractors earned $699.00 per year more than one would expect given the increases in fee schedules. Each chiropractor earned $2,329.00 per year more than was necessary to make up for losses due to inflation. The allegation that unnecessary treatments were performed on patients is countered by analysis of the services per discrete patient values by mode of practice. The increased earnings of chiropractors was accomplished by treating an increasing percentage of the population who sought health care. Comparative information was obtained from the four western provinces.     

Practical application of comfort theory in the perianesthesia setting.

Comfort management is a priority for patients in all settings. Comfort theory provides a foundational and holistic approach to comfort management. This article reviews comfort theory and presents the application of comfort theory in the perianesthesia setting. OBJECTIVES: -Based on the content of the following article, the reader will be able to (1) define comfort; (2) identify comfort interventions; and (3) discuss the importance of a goal for enhanced comfort in patients.     

The mentored clinical casebook project at Harvard Medical School.

An excellent physician must be aware of the countless issues that affect each patient's health. Many medical education programs expose students to a broad spectrum of disparate knowledge and hope they will integrate all the pieces into a coherent whole. The authors describe an explicit approach to integration used at Harvard Medical School since 2003 that aims to enhance students' learning in medical school and throughout their medical careers: the Mentored Clinical Casebook Project (MCCP). The MCCP is constructed on the premise that such integration does not occur suddenly but, rather, is an unending process. A first-year student is assigned to one clinician and follows one patient for one year. The student is expected to spend as much time with the patient as possible, in both clinical and nonclinical settings, seek help from the clinician, and consult other experts and sources to develop a complete picture of the patient's life. The student must produce a casebook that includes, but is not limited to, the patient's history; basic science, clinical, socioeconomic, and cultural issues; and self-reflection. The MCCP is intended to allow students to develop a deeper and more diverse understanding of what comprises a patient's health care life, to discern the patient as a person and the person as a patient. This educational project has been popular with students since its inception, providing them with a personal framework from which to address the needs of future patients and introducing them to how much they will continue to learn from their patients.     

A differential efficiency of adenovirus-mediated in vivo gene transfer into skeletal muscle cells of different maturity

High titre (10¹¹–10¹² pfu/ml) suspensions of autonomouslyreplication-defective type 5 human adenovirus (AV) recombinantswith different reporter gene inserts (CMV-Luciferase (Lux),CMV-ß-galactosidase (Lac Z), RSV-Lux and RSV-Lac Z)were injected Into intact quadrlceps muscles of 1–5 dayold (Group 1) or 35–45 day old (Group 2) normal mice,as well as regenerating adult mouse muscles (Group 3) and 35day old mdx muscles (Group 4). The expression of the reportergenes was quantitated 10 days and 2 months later. At 10 dayspostinjection all reporter gene expression was very high inthe neonatally injected (Group 1) muscles. In Group 2 musclesthe transduction was markedly less. In Group 3 muscles the geneexpression was significantly better than in the Group 2 muscles.In adult mdx muscles (Group 4) where spontaneous regenerationis usually present, the results were similar to those in Group3 animals. At 2 months post-injection in Group 1 animals, theRSV-Lux expression was even higher than at 10 days postinjection.The cell surface density of
