Obesity produces a significant deterioration in general and sexual health. The aim of this cross-sectional study was to investigate the impact of obesity on sexuality, illustrating the psychological constructs that may play a significant role in determining sexual functioning and satisfaction. During the psychological assessment for bariatric surgery eligibility, 171 obese men filled out a socio-demographic questionnaire, the International Index of Erectile Function (IIEF), the 20 Item-Toronto Alexithymia Scale, the Symptom Checklist-90-Revised, the Body Uneasiness Test, and the Obesity-related Disability test. A series of hierarchical multiple regression analyses highlighted how obese men sexual desire (F = 10.128, p < 0.001), erectile function (F = 63.578, p < 0.001), orgasmic function (F = 33.967, p < 0.001), intercourse satisfaction (F = 159.752, p < 0.001), and general satisfaction (F = 18.707, p < 0.001) were significantly associated with other IIEF sexual domains, difficulties in identifying feelings, psychopathological symptoms (such as depression and paranoid ideation), body image, and quality of life. Findings are useful for deepening understanding of obese male sexual response, and more generally, for analyzing the complex and multivariate relation between obesity and sexuality, supporting the need of a multidisciplinary approach to obesity care that includes professionals with specific training in sexology.

Pro/Anti-inflammatory cytokine imbalance in postischemic left ventricular remodeling.

Mediators Inflamm 2010 9;2010:974694. Epub 2010 May 9.

Division of Internal Medicine, Department of Clinical Medicine and Immunology, University of Siena, V. le Bracci, 53100 Siena, Italy.

Objectives: Cytokines play an important role in left ventricular remodeling consequent to myocardial ischemia. The aim of this study was to correlate cytokine production and lymphocyte apoptosis to post-ischemic left ventricular remodeling in patients affected by acute myocardial infarction (AMI) undergoing primary cutaneous angioplasty (PCI).

Methods: In 40 patients, affected by AMI and undergoing PCI, we evaluated peripheral blood mononuclear cells (PBMCs), tumor necrosis factor-alpha (TNF-alpha) and interleukin 10 (IL10) production and apoptosis on day 1, day 3, day 7, 1 month and 6 months after PCI. Patients were divided into two subgroups of remodeling or not remodeling by echocardiographic criteria.

Results: In the subgroup of remodeling patients, at each timepoint TNF-alpha production was increased significantly in comparison with the subgroup of not remodeling patients. IL10 production was statistically lower in remodeling subjects than in not remodeling ones 1 and 6 months after reperfusion. There were no differences between the two groups as regards lymphomonocyte apoptosis.

Conclusions: We found an increased production of pro-inflammatory cytokine TNF-alpha and a corresponding decrease of anti-inflammatory/regulatory cytokine IL10 in remodeling patients and we concluded that this cytokine imbalance resulted in pro-inflammatory effects which might contribute to the progression of left ventricular remodeling.
