Association of Maternal Obesity and Childhood Obesity: Implications for Healthcare Providers

The purpose of this critical appraisal was to assess the available literature on the association of maternal obesity as a risk factor for childhood obesity and to explore the implications for incorporating this evidence into practice. The increasing prevalence of childhood obesity, with its documented adverse health effects, is a critical public health threat in the United States and worldwide. Research studies have documented increased rates of childhood obesity associated with maternal obesity. Healthcare providers are challenged to expand their competencies to recognize the association of maternal obesity and childhood obesity and to address both primary and secondary prevention of childhood obesity. Stopping the cycle of obesity before it becomes the leading cause of preventable disease and death in the United States is a priority for community health nurses.     

Disparities in antidepressant treatment in Medicaid elderly diagnosed with depression

OBJECTIVES: To determine whether there were racial or ethnic disparities in the use of antidepressants in low-income elderly patients insured by Medicaid. DESIGN: Examination of 1998 Medicaid claims data. SETTING: Centers for Medicare and Medicaid Services Medicaid claims data for five U.S. states. PARTICIPANTS: All Medicaid recipients aged 65 to 84 with a diagnosis of depression. MEASUREMENTS: Treatment versus no treatment; in those treated, treatment with drugs was classified as old- or new-generation antidepressants. RESULTS: In 1998, 7,339 unique individuals aged 65 to 84 had at least one outpatient encounter with depression as the primary diagnosis. Nearly one in four (24.2%) received no antidepressant drug therapy, and 22% received neither psychotherapy nor an antidepressant. African-American individuals were substantially more likely to be untreated (37.1%) than Hispanic (23.6%), white (22.4%), or Asian (13.8%) individuals. In logistic regression models adjusting for sex, state, long-term care status, and age group, African Americans with a primary diagnosis of depression were almost twice as likely as whites not to receive an antidepressant within the study period (odds ratio=1.91, 95% confidence interval=1.62-2.24). Patients in long-term care facilities and those aged 65 to 74 were less likely to receive treatment. CONCLUSION: Substantial numbers of elderly Medicaid enrollees with a primary diagnosis of depression did not receive antidepressants or behavioral therapy. This gap in care disproportionately affected African-American patients.     

Focal nodular hyperplasia occurring after blunt abdominal trauma

Focal nodular hyperplasia of the liver is a benign neoplasm. The pathogenesis is unknown, but it was hypothesized that focal nodular hyperplasia may be a response to a vascular abnormality. We report on a case of focal nodular hyperplasia that developed in a young patient 1 year after a blunt hepatic injury.     

The identification of the UV degradants of melatonin and their ability to scavenge free radicals

Ultraviolet (UV) light is known to induce the generation of free radicals in biological tissues such as skin. Of these free radicals, the O2-. and particularly the.OH radical can induce cellular damage including lipid peroxidation. Thus, the use of antioxidants to prevent such damage induced by UV irradiation has received much attention recently. One such antioxidant, which has the potential to be incorporated into sunscreens, is the pineal secretory product melatonin. One of the concerns of using melatonin in sunscreens is its photostability. In the present study, we investigated the photostability of melatonin subjected to UV irradiation. In addition, we used liquid chromatography mass spectrometry (LC-MS) to identify the degradants and we also assessed the ability of the degradants to inhibit O2-. generation as well as lipid peroxidation in rat brain homogenate. The results show that UV irradiation of melatonin (0.1 mg/mL) using a 400-W lamp for 2 hr caused a significant decline of melatonin to 18% of its original concentration after 20 min, with the decline continuing until the melatonin concentration reaches zero at 120 min. The LC-MS results show that the degradants of melatonin are 6-hydroxymelatonin and N1-acetyl-N2-formyl-5-methoxykynurenamine (AFMK). These degradants were able to provide equipotent activity against potassium cyanide (KCN)-induced superoxide generation compared to non-irradiated melatonin. Thus, the study shows that although melatonin is rapidly degraded by UV irradiation, the degradants retain antioxidant activity, making melatonin a likely candidate for inclusion in sunscreens.
