Abstract
BACKGROUND AND AIMS Bariatric surgery (BS) reduces long-term mortality in comparison with medical treatment of obesity. Some studies indicate that this effect is significant for patients above mean age in different cohorts, but not for younger patients. These findings raise the question whether morbid obese patients should undergo BS as soon as possible, or whether patients might undergo surgery later in their life. METHODS We performed a post hoc analysis of two studies; we evaluated surgery-related long-term mortality in: (1) the whole cohort [857 surgery patients (163 diabetes) vs. 2086 controls (512 diabetes)]; (2) patients above mean age [> 43 years, 427 surgery patients (133 diabetes) vs. 1054 controls (392 diabetes)]; (3) patients below mean age [≤ 43 years, 432 surgery patients (30 diabetes) vs. 1032 controls (120 diabetes]. Then, we analyzed age-related long-term mortality in the whole cohort, as well as in surgery patients and in controls. Finally, we analyzed incident diseases (diabetes, cardiovascular disease, and cancer) as a function of surgery versus no-surgery and of mean age. RESULTS Surgery patients, compared with controls receiving standard medical/dietary treatment, had reduced mortality in the whole cohort (HR = 0.45, 95% CI 0.33-0.62, p = 0.001) and in the study group aged > 43 years (HR = 0.39, 95% CI 0.28-0.56, p = 0.001), but not in the study group aged ≤ 43 years (HR = 0.87, 95% CI 0.42-1.80, p = 0.711). Reduced mortality was observed in non-diabetic and diabetic patients aged > 43 years (HR = 0.37, 95% CI 0.23-0.62, p = 0.001 and HR = 0.45, 95% CI 0.27-0.74, p = 0.002, respectively) who underwent bariatric surgery. In contrast, in patients aged ≤ 43 years, no significant protective effect of bariatric surgery appeared in non-diabetic patients (HR = 0.64, 95% CI 0.24-1.71, p = 0.371), and mortality increased, almost significantly, in diabetic patients aged < 43 years (HR = 2.87, 95% CI 0.96-8.56, p = 0.058), and even more in diabetic patients aged 33-43 years; HR = 4.99, 95% CI 1.18-21.09, p = 0.029). As expected, age-related mortality was increased in the whole cohort (HR = 7.23, 95% CI 5.14-10.17, p = 0.001), in non-diabetic and diabetic controls (HR = 8.55, 95% CI 5.77-12.68, p = 0.001, and HR = 3.76, 95% CI 1.97-7.18, p = 0.001, respectively). The effect of aging was slightly reduced in surgery patients (HR = 3.76, 95% CI 1.87-7.58, p = 0.001), while it was not significant in diabetic surgery patients (HR = 0.70, 95% CI 0.26-1.90, p = 0.88), further emphasizing that diabetes per se has a strong negative effect on survival, also with concomitant bariatric surgery. In a supplementary analysis, HRs did not change when surgery and control parents were matched for the presence of diabetes. Incident diseases (cardiovascular, diabetes, and cancer) were less frequent in surgery than in control patients, irrespective of age. CONCLUSION Bariatric surgery reduces long-term mortality in comparison with medical treatment when performed in patients aged > 43 years, but not in younger patients, where it is neutral or could even increase mortality; reduction in morbidity occurs at any age.

Abstract
The aim of this study was to evaluate in morbid obesity clinical and metabolic effects related to weight loss on liver steatosis (LS), measured through chemical-shift magnetic resonance imaging (MRI) and liver enzymes. Forty obese subjects (8 M/32 W; BMI 42.8 ± 7.12 kg/m(2), mean ± SD) were evaluated for LS through ultrasound (US-LS), chemical-shift MRI (MRI-LS), liver enzymes [aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyltransferase (GGT), alkaline phosphatase (ALP)], anthropometric parameters [weight, BMI, waist circumference (WC)], lipids, insulin, insulin resistance (HOMA-IR), glycated hemoglobin (HbA1c), oral glucose tolerance test, and body composition [fat mass (FM) and fat-free mass (FFM) at bio-impedance analysis (BIA)]. Anthropometric measures, MRI-LS, BIA, and biochemical parameters were reevaluated 6 months later in 18 subjects undergoing restrictive bariatric approach, i.e., intragastric balloon (BIB, n = 13) or gastric banding (LAGB, n = 5), and in 13 subjects receiving hypocaloric diet. At baseline, US-LS correlates only with MRI-LS, and the latter correlates with ALT, AST, and GGT. After 6 months, subjects undergoing BIB or LAGB had significant changes of BMI, weight, WC, ALT, AST, GGT, ALP, HbA1c, insulin, HOMA-IR, FM, FFM, and MRI-LS. Diet-treated obese subjects had no significant change of any parameter under study; change of BMI, fat mass, and fat-free mass was significantly greater in LAGB/BIB subjects than in diet-treated subjects. Change of MRI-LS showed a significant correlation with changes in weight, BMI, WC, GGT, ALP, and basal MRI-LS. Significant weight loss after BIB or LAGB is associated with decrease in chemical-shift MRI-LS and with reduction in liver enzymes; chemical-shift MRI and liver enzymes allow monitoring of LS in follow-up studies.

Abstract
Few and mostly uncontrolled studies indicate that weight loss improves heart rate variability (HRV) in grade-3 obesity. The aim of this study was to compare in grade-3 obesity surgery and hypocaloric diet on clinical and metabolic variables and on autonomic indices of HRV. Twenty-four subjects (body mass index, BMI 45.5 ± 9.13 kg/m(2)) underwent surgery (n = 12, gastric banding, LAGB) or received hypocaloric diet (n = 12, 1,000-1,200 kg/day). Clinical [BMI, systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate] and metabolic variables [glucose, cholesterol, HDL- and LDL-cholesterol, triglycerides, AST and ALT transaminases] and 24-h Holter electrocardiographic-derived HRV parameters [R-R interval, standard deviation of R-R intervals (SDNN); low/high-frequency (LF/HF) ratio, and QT interval] were measured at baseline and after 6 months. The two groups were identical at baseline. BMI (-7.5 ± 3.57 kg/m(2), mean ± SD), glucose (-24.1 ± 26.77 mg/dL), SBP (-16.7 ± 22.19 mmHg) and DBP (-6.2 ± 8.56 mmHg) decreased in LAGB subjects (p < 0.05) and remained unchanged in controls. At 6 months, SDNN increased in LAGB subjects (+25.0 ± 37.19 ms, p < 0.05) and LF/HF ratio diminished (2.9 ± 1.84 vs. 4.9 ± 2.78; p = 0.01), with no change in controls; LF (daytime) and HF (24 h and daytime) increased in LAGB subjects, with no change in controls. Decrease in BMI correlated with SBP and DBP decrease (p < 0.05), and DBP decrease correlated with HR decrease (p < 0.05) and QT shortening (p < 0.05). Weight loss is associated with improvement of glucose metabolism, of blood pressure, and with changes in time and frequency domain parameters of HRV; all these changes indicate recovery of a more physiological autonomic control, with increase in parasympathetic and reduction in sympathetic indices of HRV.

Abstract
An increased prevalence of female sexual dysfunction (FSD) has been reported in women with diabetes mellitus (DM). Our aim was to evaluate correlates (psychological, cardiovascular, and neurophysiologic) of FSD in DM women without chronic diabetic complications. Female Sexual Function Index (FSFI), Beck Depression Inventory (BDI), Michigan Diabetic Neuropathy Index (DNI), and the symptoms of diabetic neuropathy (SDN) questionnaires, metabolic variables, endothelial vascular function (flow-mediated dilation, FMD), echocardiography, and electromyography were studied. 109 pre-menopausal women (18-50 years) [48 with DM (14 type 1 DM, 34 type 2 DM, duration 12.6 ± 1.91 years), and 61 healthy women] received the above questionnaires; physical activity, smoking habits, parity, BMI, waist circumference, HOMA-IR index, fibrinogen, cholesterol (total, HDL, LDL), triglycerides, HbA1c, high-sensitivity C-reactive protein, total testosterone, and estradiol were measured; echocardiography, assessment of intima-media thickness (IMT), FMD, ECG (heart rate and Qtc, indexes of sympathetic activity), and electromyography were performed. FSFI total score and score for arousal, lubrication, and orgasm domains were lower in DM women than in controls (P < 0.05); DM women had higher BDI, Doppler A wave peak velocity, DNI, and SDN score (P < 0.001 to P < 0.04). Doppler E wave peak velocity, peroneal, posterior tibial and sural nerves conduction velocity and amplitude were lower in diabetic women than in controls (P < 0.05 to P < 0.001). FSFI score was positively correlated with physical activity, Doppler E wave peak velocity, and peroneal nerve amplitude and negatively with BDI, parity, IMT, SDN, and HbA1c (P < 0.05 to P < 0.001). At stepwise regression, SDN score (negatively) and Doppler E wave peak velocity (positively) predicted FSFI score (r = 507, P < 0.001). In conclusion, cardiovascular and neurological impairments are associated with FSD in diabetic women. Follow-up studies are required to evaluate sexual dysfunction as a risk factor for future cardiovascular or neurological events.

Abstract
OBJECTIVE Malabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the changes of cholesterol metabolism induced by malabsorptive and restrictive surgery independent of weight loss. RESEARCH DESIGN AND METHODS In a nonrandomized, self-selected, unblinded, active-comparator, bicenter, 6-month study, glucose metabolism (blood glucose and serum insulin levels and homeostasis model assessment of insulin resistance [HOMA-IR] index) and cholesterol metabolism (absorption: serum campesterol and sitosterol levels; synthesis: serum lathosterol levels; catabolism: rate of appearance and serum concentrations of serum 7-α- and serum 27-OH-cholesterol after infusions of deuterated 7-α- and 27-OH-cholesterol in sequence) were assessed in grade 3 obesity subjects undergoing BIBP (n = 10) and AGB (n = 10). Evaluations were performed before and 6 months after surgery. RESULTS Subjects had similar values at baseline. Weight loss was similar in the two groups of subjects, and blood glucose, insulin levels, HOMA-IR, and triglycerides decreased in a similar way. In contrast, serum cholesterol, LDL cholesterol, non-HDL cholesterol, serum sitosterol, and campesterol levels decreased and lathosterol levels increased only in BIBP subjects, not in AGB subjects. A significant increase in 7-α-OH-cholesterol occurred only with BIBP; serum 27-OH-cholesterol decreased in both groups. CONCLUSIONS Malabsorptive surgery specifically affects cholesterol levels, independent of weight loss and independent of glucose metabolism and insulin resistance. Decreased sterol absorption leads to decreased cholesterol and LDL cholesterol levels, accompanied by enhanced cholesterol synthesis and enhanced cholesterol catabolism. Compared with AGB, BIBP provides greater cholesterol lowering.

Abstract
Background Bariatric surgery is able to improve glucose and lipid metabolism, and cardiovascular function in morbid obesity. Aim of this study was to compare the long-term effects of malabsorptive (biliary pancreatic diversion, BPD), and restrictive (laparoscopic gastric banding, LAGB) procedures on metabolic and cardiovascular parameters, as well as on metabolic syndrome in morbidly obese patients. Methods 170 patients studied between 1989 and 2001 were called back after a mean period of 65 months. 138 patients undergoing BPD (n = 23) or LAGB (n = 78), and control patients (refusing surgery and treated with diet, n = 37) were analysed for body mass index (BMI), blood glucose, cholesterol, and triglycerides, blood pressure, heart rate, and ECG indexes (QTc, Cornell voltage-duration product, and rate-pressure-product). Results After a mean 65 months period, surgery was more effective than diet on all items under evaluation; diabetes, hypertension, and metabolic syndrome disappeared more in surgery than in control patients, and new cases appeared only in controls. BPD was more effective than LAGB on BMI, on almost all cardiovascular parameters, and on cholesterol, not on triglyceride and blood glucose. Disappearance of diabetes, hypertension, and metabolic syndrome was similar with BPD and with LAGB, and no new cases were observed. Conclusion These data indicate that BPD, likely due to a greater BMI decrease, is more effective than LAGB in improving cardiovascular parameters, and similar to LAGB on metabolic parameters, in obese patients. The greater effect on cholesterol levels is probably due to the different mechanism of action.

Abstract
BACKGROUND AND AIM Bariatric surgery induces significant weight loss and improves glucose metabolism in obese patients (BMI>35 kg/m(2)). Our aim was to compare restrictive (LAGB, laparoscopic gastric banding) and malabsorptive approaches (BIBP, biliary-intestinal bypass) on the loss of fat-free mass (FFM), fat mass (FM), and on changes of glucose and lipid metabolism. METHODS AND RESULTS Body composition (bio-impedance analysis, BIA), blood glucose (BG), insulin, triglycerides, total- and HDL-cholesterol, liver enzymes (AST and ALT) were measured at baseline and 1 year after surgery in patients undergoing LAGB, BIBP, and in diet-treated control patients. In the main study, with patients matched for initial BMI (43-55 kg/m(2), LAGB=24, BIBP=12, controls=6), decreases of BMI, FM, BG and cholesterol were greater in patients with BIBP than with LAGB (p<0.01), while decreases of FFM, insulin, HOMA-IR and triglycerides were similar. No effects on BMI, FM, FFM, BG, insulin, HOMA-IR or cholesterol were observed in the control patients. Decreases of BG, insulin, HOMA-IR, cholesterol and triglycerides correlated with FM but not with FFM decrease. Similar results were obtained in an additional study in patients with a different initial BMI (LAGB=25, BIBP=6, controls=24) and when considering all subjects together. A decrease of liver enzymes (ALT) was greater with LAGB than with BIBP, and HDL-cholesterol increased with LAGB and decreased with BIBP. CONCLUSION BMI, FM, BG and cholesterol decrease more with malabsorptive than with restrictive surgery, while FFM, insulin, HOMA-IR and triglycerides decrease in a similar way. FFM loss is of low entity. Changes of glucose and lipid metabolism are proportional to a decrease of fat mass but not of fat-free mass.

Abstract
Diagnosis of erectile dysfunction (ED) requires anamnestic investigation, being rarely spontaneously declared by patients. ED occurs frequently in diabetes mellitus, and anecdotal evidence suggests that ED occurs in obesity and in hypothyroidism. The aim of this study was to evaluate the prevalence of ED in patients affected by thyroid disorders (hypothyroidism and hyperthyroidism), in comparison with control subjects and with patients at risk for ED, such as patients with obesity and with type II diabetes mellitus, and the role of age. Spontaneous deposition and International Index of Erectile Dysfunction (IIEF)-5 questionnaire were considered for control subjects and for all patients. Spontaneous deposition of ED occurred for three diabetic patients, never for obese patients, thyroid patients and controls, confirming the value of IIEF-5 in detecting ED. ED was more frequent in obese subjects (42%), and in patients affected by thyroid diseases (59%), than in controls (30%), although less frequent than in type II diabetes mellitus (81%). Both below and above the age of 50 years, ED score was worse in thyroid patients than in control subjects, while ED was more frequent in obese patients than in control subjects only below the age of 50 years.

Abstract
The clinical effectiveness of 23-valent pneumococcal vaccine in human immunodeficiency virus (HIV)-infected patients is controversial, because of the low immunological response in these subjects. We studied the clinical response of pneumococcal vaccine and the relative impact of influenza vaccine by administering both pneumococcal and influenza vaccine in a group of 150 HIV patients belonging to all CDC categories. In the group of 90 HIV-infected patients vaccinated against both pneumonia and influenza virus, there was a low incidence of mild influenza (13.3%) and no case of pneumococcal pneumonia. On the contrary, among 60 nonvaccinated HIV patients, 61.6% underwent mild to severe influenza and two developed pneumococcal pneumonia. 23-valent pneumococcal vaccine (PV) seems to be clinically effective in preventing pneumonia in HIV-infected patients, and even more if strengthened by influenza vaccine.

Abstract
The aim of this study was to assess the relationship between homocysteine (tHcy), folate and vitamin B12 levels, urinary albumin excretion, and arterial blood pressure in patients with non-insulin-dependent diabetes mellitus (NIDDM). Our study was carried out in 33 NIDDM patients (16 men, 17 women) and 16 healthy volunteers as controls (seven men, nine women). Fasting and postmethionine load plasma tHcy levels were assessed, together with folate, vitamin B12, and urinary albumin excretion levels. In NIDDM patients, there were correlations between folate and mean arterial pressure (r = -0.352, P = .046), folate and systolic blood pressure (r = -0.437, P = .013), folate and vitamin B12 (r = 0.499, P = .004), tHcy and vitamin B12 (r = -0.348, P = .04), ln tHcy and ln folate (r = -0.404, P = .01), and, lastly, between tHcy, either fasting or postload, and urinary albumin excretion. Patients with elevated tHcy levels had significantly higher diastolic blood pressure (P = .04) and mean arterial pressure (P = .03). Otherwise, higher folate values were associated with lower systolic blood pressure (P = .004) and mean arterial pressure (P = .02). In addition, NIDDM patients with complications presented higher tHcy basal values than the group without complications (P = .003). A particular propensity of such patients towards endothelial dysfunction could explain the presence of correlations between these metabolic parameters and arterial blood pressure.

Abstract
The study aim was to assess the relationship between homocyst(e)inemia and microalbuminuria in non-insulin-dependent diabetes mellitus (NIDDM) patients. The study was performed on 33 NIDDM patients (16 males and 17 females), and 16 healthy control subjects (seven males and nine females). Plasma fasting and post-methionine load homocyst(e)ine (tHcy), together with other parameters that could modify tHcy levels, were assessed. There were no significant differences between NIDDM patients and controls for fasting tHcy (8.12 +/- 3.17 v 7.19 +/- 2.40 micromol/L) and post-methionine load tHcy (26.51 +/- 11.50 v 25.06 +/- 10.76 micromol/L). Moreover, there was a significant correlation between urinary albumin excretion (UAE) and fasting tHcy (r = .340, P = .05) and post-methionine load tHcy (r = .502, P = .004) in NIDDM patients. Fasting tHcy was correlated both with post-methionine load tHcy (r = .429, P = .01) and with vitamin B12 (r = -.349, P = .04) in NIDDM patients. Microalbuminuric NIDDM patients had higher fasting tHcy (9.05 +/- 3.83 micromol/L) than normoalbuminurics (7.12 +/- 1.95 micromol/L). In addition, NIDDM patients with complications presented higher fasting tHcy values than the group without complications (9.61 +/- 3.34 v 6.53 +/- 2.09 micromol/L, Kolmogorov-Smirnov two-sample test for nonparametric data [KS] = 1.794, P = .003), without any other significant differences in the parameters considered. tHcy could be an important risk factor worsening the prognosis in NIDDM patients, especially microalbuminuric patients. Microalbuminuric NIDDM patients could be particularly prone to hyperhomocyst(e)inemia, probably due to endothelial or renal dysfunction with a reduction in the scavenging of tHcy.

Abstract
Conflicting evidence has been reported on the metabolic fate of glucose following oral ingestion. We measured the metabolic pattern of gluconeogenic substrates as alanine, predominantly produced by muscle, and lactate after an oral glucose load in ten normal subjects and in eighteen non-insulin dependent diabetes mellitus (NIDDM) subjects. Neither in normal or NIDDM subjects were significant increases in plasma alanine observed, whereas a significant increase in plasma lactate was observed at 60, 90 and 120 min after a glucose load. Although a similar behaviour in plasma alanine and lactate between normal and NIDDM subjects was found, in NIDDM significantly higher levels of plasma alanine and lactate were found at each time. From these observations we conclude: 1) when glucose is ingested under post-absorptive conditions, since plasma alanine levels do not change concurrently with lactate increase, muscle tissue does not play a predominant role in glucose disposal 2) after an oral glucose load, the pattern of gluconeogenic precursors (alanine and lactate) is similar in normal and NIDDM subjects 3) the main cause of fasting and post-prandial hyperglycemia in NIDDM subjects may be due to an overproduction of alanine as well as lactate.
