OBJECTIVE: Muscle dysmorphia is a form of body dysmorphic disorder in which individuals develop a pathological preoccupation with their muscularity. METHOD: The authors interviewed 24 men with muscle dysmorphia and 30 normal comparison weightlifters, recruited from gymnasiums in the Boston area, using a battery of demographic, psychiatric, and physical measures. RESULTS: The men with muscle dysmorphia differed significantly from the normal comparison weightlifters on numerous measures, including body dissatisfaction, eating attitudes, prevalence of anabolic steroid use, and lifetime prevalence of DSM-IV mood, anxiety, and eating disorders. The men with muscle dysmorphia frequently described shame, embarrassment, and impairment of social and occupational functioning in association with their condition. By contrast, normal weightlifters displayed little pathology. Indeed, in an a posteriori analysis, the normal weightlifters proved closely comparable to a group of male college students recruited as a normal comparison group in an earlier study. CONCLUSIONS: Muscle dysmorphia appears to be a valid diagnostic entity, possibly related to a larger group of disorders, and is associated with striking and stereotypical features. Men with muscle dysmorphia differ sharply from normal weightlifters, most of whom display little psychopathology. Further research is necessary to characterize the nosology and potential treatment of this syndrome. 相似文献
Parental awareness of risk factors for sudden infant death syndrome (SIDS) and infant care practices were compared in an area of relative deprivation and one of relative affluence in Cardiff. Awareness was high in both areas. More infants slept on the side in the deprived area (p < 0.02). One in three babies was exposed to cigarette smoking, significantly more in the deprived area (p < 0.001). Health professionals should discourage side sleeping and smoking, especially in areas of deprivation. 相似文献
Introduction: Hepatocellular carcinoma (HCC) is one of the most common and lethal cancers. Progress has been made in treatment of HCC; however, improved outcomes are much needed. The increased metabolic needs of cancer cells underscore the importance of metabolic pathways in cancer cell survival. Lipid metabolism has a role in HCC development; aberrant overexpression of several key enzymes is seen in many solid human tumors.
Areas covered: We discuss aberrant lipid metabolism and the promise of multiple targets, in particular related to HCC treatment. We searched PubMed and clinicaltrials.gov for published and unpublished studies from 2000 to 2019. These terms were used: lipids, fatty acid metabolism, lipid metabolism, liver cancer, HCC, de novo fatty acid synthesis, ATP citrate lyase, stearoyl CoA denaturase, fatty acid synthase, acetyl coenzyme A carboxylase, CD147, KLF4, monoglyceride lipase, AMP activated protein kinase.
Expert opinion: The importance of dysregulation of fatty acid synthesis in cancer is a growing area of research. HCC demonstrates significant alteration in lipid metabolism, representing great potential as a target for novel therapeutics. Various agents have demonstrated promising anti-neoplastic activity. This strategy deserves further development for improved outcomes. 相似文献
Mycosis fungoides (MF), the most common cutaneous T‐cell lymphoma (CTCL), is rare in childhood. The prognosis and response to treatment are poorly described in children. The objective of the current study was to evaluate the response to phototherapy in a pediatric cohort. A retrospective cohort study of all patients diagnosed with MF before the age of 18 years and referred to the regional CTCL phototherapy service was performed between January 1990 and April 2012. Twenty‐eight patients were identified (13 boys, 15 girls). The mean age at presentation was 11.6 ± 3.9 years. The hypopigmented variant was noted in 79% of patients. All patients had stage I disease (IA = 10, IB = 17, unknown = 1). The median follow‐up after diagnosis was 43 months (range 6–274 mos). Narrowband ultraviolet B (NbUVB; 311 nm) was used as first‐line phototherapy in 18 patients and psoralen (bath) plus ultraviolet A (PUVA) was used in 8 patients. Complete or partial response was observed in 19 of 22 patients (86%). A further course of phototherapy was required in 7 of 12 patients (58%) treated with NbUVB after a median of 4 months (range 4–29 mos). A further course of phototherapy was required in four of eight patients (50%) successfully treated with PUVA after a median of 45.5 months (range 30–87 mos). No disease progression was noted over the follow‐up (median 43 mos). The majority of patients in our cohort had hypopigmented MF. Phototherapy offers an effective option for treatment of childhood MF, although the period of remission may be greater in patients treated with PUVA. 相似文献
