Adiponectin,Leptin and Ghrelin Levels in Obese Adolescent Girls with Polycystic Ovary Syndrome

Study ObjectiveTo evaluate the differences in adipokines, namely adiponectin, leptin, and ghrelin, in obese adolescent girls with or without polycystic ovary syndrome (PCOS).DesignCase-control study.SettingUniversity hospital.Participants38 adolescent girls (age 15-20 years). Group I: 17 Obese adolescent girls with PCOS (BMI ≥ 30 kg/m²); Group II: Control group of 21 obese adolescent girls (BMI ≥ 30 kg/m²).Main Outcome MeasuresAdiponectin, leptin, and ghrelin measurements.ResultsLH, LH/FSH, and cortisol levels were significantly higher in the obese PCOS girls compared to the obese controls (6.94 ± 3.28 vs 4.44 ± 1.79; 1.50 ± 0.72 vs 0.90 ± 0.36; 16.02 ± 4.28 vs 12.46 ± 5.29; P < .05, respectively). Adiponectin, leptin, and ghrelin levels were similar between the obese PCOS girls and the obese controls (11.13 ± 6.00 vs 15.26 ± 12.66; 23.66 ± 11.54 vs 23.11 ± 11.17; 665.69 ± 402.12 vs 650.22 ± 467.73, respectively). Adiponectin negatively correlated with BMI (r = ?0.32; P = .04) and positively correlated with fasting glucose (r = 0.40; P = .01). Leptin positively correlated with BMI (r = 0.534; P = .001), estradiol (r = 0.354; P = .02), and TSH (r = 0.374; P = .02). No significant correlation was found between ghrelin and the test parameters.ConclusionAmong obese adolescents with PCOS, adiponectin, and leptin levels do not seem to be determined by the existence of PCOS, while ghrelin presents no significant correlation.     

Risk factors for childhood respiratory disease. Analysis of pulmonary function

Four thousand elementary-school-age children from a rural area of western Pennsylvania participated in a cross-sectional survey that consisted of a standardized respiratory questionnaire completed by their parents and spirometric testing at school. Spirographic tracings were digitized to obtain the FVC, FEV0.75, FEF25-75, Vmax75, and Vmax90, which were standardized for height, age, and sex for the subsequent analyses. Independent associations of potential risk factors with the standardized pulmonary function measures were evaluated with multiple regression techniques. Asthma, persistent wheeze, and parental smoking habits, especially those of the mothers, were associated with lower flow rates. The effect of parental smoking was primarily due to smoking by the mother and was stronger in girls. In female children of currently smoking mothers, FEF25-75 was 96% of predicted, Vmax75 was 95% of predicted, and Vmax90 was 92% of predicted; each flow measure was 98% of predicted in male children of smoking mothers. Prolonged hospitalization at birth was independently associated with lower FEV0.75 and flow rates. Low socioeconomic status was associated with lower FVC and FEV0.75. Neither current gas stove use nor a history of severe chest illness before 2 yr of age were independently associated with lower levels of pulmonary function.     

Diagnosis of comorbid psychiatric disorders in substance users assessed with the Psychiatric Research Interview for Substance and Mental Disorders for DSM-IV

OBJECTIVE: The authors used the Psychiatric Research Interview for Substance and Mental Disorders for DSM-IV (PRISM-IV) to test the reliability of DSM-IV-defined disorders, including primary and substance-induced disorders, in substance-abusing subjects. METHOD: Substance-abusing patients (N=285) from substance abuse/dual-diagnosis treatment settings and mental health treatment settings participated in test and blind retest interviews with the PRISM-IV, which includes specific guidelines for assessment of substance abusers. RESULTS: Kappas for primary and substance-induced major depressive disorder ranged from 0.66 to 0.75. Reliability for psychotic disorders, eating disorders, antisocial personality disorder, and borderline personality disorder was in the same range. Reliability for most anxiety disorders was lower. Reliability was good to excellent (kappas >/=0.65) for most substance dependence disorders. Continuous measures (severity, age at onset) had intraclass correlation coefficients >0.70 with few exceptions. Reliability was better for primary than for substance-induced disorders, although not greatly so. CONCLUSION: Most DSM-IV psychiatric disorders can be assessed in substance-abusing subjects with acceptable to excellent reliability by using specifically designed procedures. Good reliability improves the likelihood of significant study results.     

American Cancer Society Perspectives on Environmental Factors and Cancer

Cancer prevention is central to the mission of the American Cancer Society (ACS). The ACS's prevention activities take many forms, but are primarily focused on modifiable risk factors that have been demonstrated to have the largest impact on cancer risk in the general population (with particular emphasis on tobacco use because of its large impact on cancer), and well‐proven policy and program interventions. The ACS addresses nutrition, physical inactivity and obesity, alcohol consumption, excessive sun exposure, prevention of certain chronic infections, and selected other environmental factors through a variety of venues, including consensus guidelines (eg, nutrition and physical activity, human papillomavirus vaccination) and developing educational materials for health care providers and the general public. In contrast to the broad definition of environmental factors used by the ACS and most other public health agencies, some members of the general public associate the term “environmental” only with toxic air and water pollutants and other, predominantly manmade, hazards that people encounter, often involuntarily, in their daily life. This article will provide an overview of the ACS's approach to the prevention of cancer associated with such toxic pollutants in the context of its mission and priorities with respect to cancer prevention.
