Mild hyperhomocysteinemia and the common C677T polymorphism of methylene tetrahydrofolate reductase gene are not associated with the metabolic syndrome in Type 2 diabetes.

A moderate increase of total homocysteine (tHcy) plasma levels seems to increase cardiovascular disease (CVD) risk in Type 2 diabetic subjects, but its relationship with diabetes and insulin-resistance is still controversial. We examined whether mild hyperhomocysteinemia and its major genetic determinant would cluster with the metabolic syndrome (MS) in Type 2 diabetes. One hundred Type 2 diabetic subjects with and without MS were enrolled in the study. Fasting tHcy, vitamin B12, and folate plasma levels, insulin-resistance [assessed by homeostasis model assessment, (HOMAIR)] and the methylene tetrahydrofolate reductase (MTHFR) C677T genotype were assessed in all the participants. Geometric mean tHcy concentration and the prevalence of mild hyperhomocysteinemia, as commonly defined by tHcy >/=15 micromol/l, were comparable in diabetic subjects with and without MS, even after adjustment for age, sex, vitamin B12, folate and creatinine levels. In both groups, the MTHFR C677T genotype distribution was not significantly different from the Hardy-Weinberg equilibrium, with a TT homozygous frequency of 21% in subjects with and 18% in those without the syndrome (p=ns). tHcy plasma levels and the degree of insulin-resistance did not differ across MTHFR genotypes in both groups, even after multivariable adjustment. Overall, tHcy significantly correlated with creatinine (r=0.25; p=0.009) and trygliceride concentrations (r=0.24; p=0.02), but not with HOMAIR. At multivariate analysis, only creatinine was significantly correlated with tHcy levels (beta=0.42; p=0.001). In conclusion, hyperhomocysteinemia and the common C677T variant of MTHFR gene are not associated with MS in Type 2 diabetic subjects.

Predictors of high level of burden and distress in caregivers of demented patients: results of an Italian multicenter study.

BACKGROUND: Considerable suffering is experienced by carers of patients with dementia. Most existing studies do not consider the coexistence of subjective and objective aspects that cause, interacting to each other, this suffering. OBJECTIVES: In this study we: (1) define the high-risk group of caregivers on the bases of the scores obtained on the four scales evaluating burden, distress, depression and anxiety (BDDA) taken into account simultaneously and (2) evaluate risk factors related to the high level of BDDA. SUBJECTS AND METHODS: 419 elderly outpatients with dementia and their caregivers were enrolled. Patients were evaluated for their cognitive, neuropsychological and functional impairment and for comorbidity. Caregivers were evaluated with four scales for the assessment of burden, distress related to neuropsychological disturbances, depression and anxiety. Cluster analysis was used to identify the group with the High level of BDDA (HBDDA). RESULTS: By multiple logistic analysis, disability, specific behavioural disturbances of the patients as well as caregiver's age, type of relationship and living in the south of Italy were observed to be a major risk factor for HBDDA. CONCLUSION: The targeted use of scales specifically assessing BDDA of the caregiver and the identification of particular patient and caregiver characteristics are able to allow a precise and early definition of caregivers at high risk of burden and distress. This might be helpful in planning the correct social/clinical/rehabilitative approach.

Inflammatory markers in women with a recent history of gestational diabetes mellitus.

Gestational diabetes mellitus (GDM) is a risk factor for both Type 2 diabetes (DM2) and insulin-resistance syndrome (IRS). C-reactive protein (CRP), fibrinogen and leukocyte count are increased in the IRS and predict DM2 and cardiovascular disease (CVD). The chemochine monocyte chemoattractant protein-1 (MCP-1/CCL2) is also elevated in DM2 and CVD. Recent evidence suggests a relation between chronic inflammation and GDM, but post-delivery information on inflammatory markers in these high-risk women is lacking. Serum levels of CRP, fibrinogen, MCP-1/ CCL2, and leukocyte blood count have been assessed in 26 women with and 26 women without a recent history of GDM, matched for age, body mass index (BMI), post-partum duration and parity. DM2 was excluded in all the participants by an oral glucose tolerance test (OGTT). Women with previous GDM showed significantly higher CRP (p=0.007) and fibrinogen (p=0.02) serum concentrations, whereas MCP-1/CCL2 serum levels and leukocyte blood count were comparable in the two groups. Overall, CRP levels significantly correlated with BMI (r=0.40, p=0.03), waist-to-hip ratio (WHR) (r=0.44, p=0.001), fasting insulin (r=0.27, p=0.04), insulin-resistance assessed by means of the homeostatic model (HOMA) (r=0.28, p=0.04), and fibrinogen concentration (r=0.49, p=0.0001). At linear regression analysis, only WHR and fibrinogen were independently associated with CRP levels. In conclusion, the increase of inflammatory markers may be one of the first detectable disorders in healthy women at high risk of DM2 and IRS, like those with a GDM history.

Insulin aspart improves meal time glycaemic control in patients with Type 2 diabetes: a randomized, stratified, double-blind and cross-over trial.

AIMS: This randomized, multi-centre, double-blind, stratified, two period, cross-over trial was undertaken to assess the pharmacokinetics and pharmacodynamics of insulin aspart injected immediately before compared with regular human insulin injected 30 min before a Mediterranean-style meal in 37 (23 M, 14 F) patients with Type 2 diabetes. METHODS: Insulin aspart or regular human insulin was given subcutaneously (0.15 U/kg) in random sequence, using a double-dummy technique (at one visit: human regular insulin at t=-30 min and placebo at t=0; at the other visit: placebo at t=-30 min and aspart insulin at t=0). Serum glucose and insulin concentrations (15 points) were measured after each meal for 240 min. RESULTS: Post-prandial glycaemic excursions were 20% lower with insulin aspart (IAsp) compared with regular human insulin (HI) treatment [ratio (Iasp/HI)=0.80, CI=(0.66-0.98), P=0.034]. The maximum serum glucose (SG) concentration was similar for the two treatments (P=NS). The (median) time to maximum SG was 25 min shorter for IAsp compared with HI (P=0.048). Maximum serum insulin concentration was higher after IAsp compared with HI (P=0.023) as well as the area under the 4-h serum insulin curve (P=0.006). Furthermore, the time to maximum serum insulin concentration was 27 min shorter after IAsp (P=0.039), even though IAsp was injected 30 min after HI. No adverse events occurred during the trial. CONCLUSIONS: In patients with Type 2 diabetes a more favourable insulin profile and a better glycaemic control were found with IAsp injected immediately before compared with HI injected 30 min before a Mediterranean-style meal.

Effects of a long-term treatment with raloxifene on insulin sensitivity in postmenopausal women.

AIMS/HYPOTHESIS: Our aim was to investigate the effect of long-term administration of raloxifene, a selective estrogen receptor modulator, on insulin sensitivity, glucose tolerance and plasma lipid concentrations in a group of postmenopausal women. METHODS: A total of 24 women with postmenopausal osteoporosis were consecutively enrolled and randomly assigned to take raloxifene, 60 mg/day for 12 months or placebo. At baseline and after 6 and 12 months, in each subject insulin sensitivity (M-index) was assessed by means of an euglycaemic hyperinsulinaemic clamp. Plasma concentrations of total cholesterol, triglycerides and HDL-cholesterol were also measured and glucose tolerance was evaluated. RESULTS: In the raloxifene-treated group, the M index decreased after 6 and 12 months with respect to the placebo group (-21%, p=0.042 and -23%, p=0.018, respectively). Neither fasting plasma glucose nor glucose tolerance changed in the raloxifene-treated group, compared to the placebo group. Low density lipoprotein cholesterol concentrations decreased at 12 months (-13%, p=0.047). CONCLUSION/INTERPRETATION: A long-term treatment with raloxifene in osteoporotic, otherwise healthy post-menopausal women can reduce insulin sensitivity without affecting glucose tolerance.

Preventive-comprehensive assessment (PCA): a new screening method for subclinical cognitive problems.

Physicians often need to be able to assess cognition in a simple way, particularly for screening of subclinical processes in aged people. This paper describes a new, quick test battery called preventive-comprehensive assessment (PCA). It consists of six various testing items (repetition of three words, back-spelling of the word "sport", problem searching ina complex picture, recall of the three words, three progressive colored matrices, clock drawing test), evaluating language, recent memory, executive function, judgment and thinking capacities. The total scores. compared to the normal performance of different age groups, allow us to distinguish between normal and pathological status. If abnormal results are recorded, we need to perform further and deeper neuropsychological investigations, in order to obtain the possibly exact diagnosis. The PCA battery is sensitive and reliable; it can be used in itself, or as a part of a more complex battery of an intense comprehensive evaluation (ICE), carried out in population screening aimed at promoting healthy and active aging.

The chronically ill elderly patients discharged from the hospital: interim report from a controlled study of home care attendance.

This controlled study evaluated various outcomes in a group of 127 chronically ill and frail elderly patients when discharged from a hospital ward, and cared at home, enrolled during 12 months starting from September 2001. The observation of patients is programmed to be of two years from enrollment, with a scheduled program of follow up at baseline,6, 12, and 24 months. Patients (of both sexes) were randomly assigned to one of two groups: (i) Control group (61 patients: mean age 85.2 years) having a usual home care program of assistance, guaranteed by the Social Health Care Service. (ii) Intervention group (66 patients: mean age 83.2 years), for whom the program of care mentioned above was integrated providing collaboration of a home care attendant. This was a lay-working person who has attended a specializing course about care of the elderly and of the very frail. The home attendance was provided for 4-10 hrs daily, according to a program established by a Geriatric Evaluation Unit. The team evaluated the patients at their home,deciding the amount of hours of attendance in the presence of the caregiver. The financial cost of the additional home care attendance was sponsored, totally or in part, according to the financial situation of the patient's family, by the "Fondazione del Monte di Bologna e di Ravenna". This report takes into consideration only few preliminary data, coming from the first 6 months of observation of all the patients included. The two groups were homogeneous when compared statistically at baseline. Data coming form laboratory and biological analysis will be available only at the end of the project as they are recorded in a blind methodology. A lower degree of mortality and of dropouts in the intervention group was observed,compared to the control group, already at 6 months. These outcomes can be considered favorable, and perhaps can be related to the various benefits gained by additional program of home attendance.

Correlates of total homocysteine plasma concentration in type 2 diabetes.

BACKGROUND: Although well-defined in the general population, correlates of total homocysteine (tHcy) plasma concentration have not been sufficiently evaluated in diabetes. We investigated factors potentially associated with tHcy concentration in a cohort of type 2 diabetic subjects. MATERIALS AND METHODS: The common methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism, fasting tHcy, vitamin B12 and folate plasma levels were assessed in 312 diabetic subjects, whose clinical, metabolic and lifestyle information was also available. RESULTS: The MTHFR genotype distribution was comparable to the Hardy-Weinberg equilibrium, with an overall TT homozygous frequency of 22%. Fasting tHcy concentration was significantly higher in men than in women (P < 0.001). Multivariate-adjusted tHcy concentration was significantly different across the quartiles of age (P < 0.001), folate (P = 0.01), vitamin B12 (P = 0.03), creatinine concentrations (P = 0.001) and smoking (P = 0.02). Overall, significant trends were noted for creatinine clearance (P for trend = 0.02) and systolic blood pressure (BP) (unadjusted P for trend = 0.01), whereas no differences were noted according to BMI, diastolic BP, presence of hypertension, and diabetes-related variables, such as diabetes duration, fasting glucose and glycated haemoglobin concentrations, current treatment and diabetes long-term complications. Total homocysteine levels significantly correlated with age, systolic BP, vitamin B12, creatinine and creatinine clearance, but only age, creatinine, folate and vitamin B12 levels were independently associated with tHcy concentration in stepwise regression analysis. CONCLUSIONS: Age, creatinine, folate, vitamin B12, and to a minor extent, sex, smoking, TT genotype and systolic BP were significantly associated with Hcy plasma concentration in type 2 diabetes, whereas no significant associations were noted with diabetes-related variables.

Musculoskeletal pain in Europe: its impact and a comparison of population and medical perceptions of treatment in eight European countries.

OBJECTIVES: To describe the impact of musculoskeletal pain (MP); to compare management of MP by the population and by primary care physicians; and to identify misconceptions about treatment. METHODS: 5803 people with MP and 1483 primary care physicians, randomly selected, in eight European countries were interviewed by telephone. A structured questionnaire was used to ask about usual management of MP and perceived benefits and risks of treatment. Current health status (SF-12) was also assessed. RESULTS: From primary care physicians' perceptions, MP appears to be well managed. All presenting patients are offered some form of treatment, 90% or more doctors are trying to improve patients' quality of life, and most are aware and concerned about the risks of treatment with NSAIDs. From a population perspective, up to 27% of people with pain do not seek medical help and of those who do, several wait months/years before seeing a doctor. 55% or fewer patients who have seen a doctor are currently receiving prescription treatment for their pain. Communication between doctors and patients is poor; few patients are given information about their condition; and many have misconceptions about treatment. CONCLUSIONS: Management of MP is similar across eight European countries, but there is discordance between physician and patient perspectives of care. Some people with pain have never sought medical help despite being in constant/daily pain. Those who do seek help receive little written information or explanation and many have misperceptions about the benefits and risks of treatment that limit their ability to actively participate in decisions about their care.

Validation of the Italian version of the WHO-Well-Being Questionnaire (WHO-WBQ) and the WHO-Diabetes Treatment Satisfaction Questionnaire (WHO-DTSQ).

AIM: To validate the Italian version of the World Health Organization (WHO)-Well-Being Questionnaire (WBQ) and the WHO-Diabetes Treatment Satisfaction Questionnaire (DTSQ) in Type 1 and Type 2 diabetic patients. METHODS: The cultural adaptation of the questionnaires was performed by using standard forward/backward techniques. Internal consistency reliability was estimated by Cronbach's alpha coefficient. Construct validity was evaluated using the Short Form-36 (SF-36) Health Status Questionnaire. Finally, the discriminative properties of the questionnaires were evaluated relative to the patients' characteristics. The questionnaires were administered to a random sample of patients identified in twelve outpatient diabetes clinics. RESULTS: Overall, 412 subjects were recruited, of whom 96 (23%) with Type 1 diabetes. Item-scale correlations were >0.40 for all the items. Cronbach's alpha coefficient was 0.86 for the WHO-DTSQ and ranged between 0.79 and 0.91 for the WHO-WBQ. High correlations were found between WHO-WBQ scales and the mental dimensions of the Short Form-36 (SF-36) questionnaire, but not between WHO-DTSQ and SF-36 scores. Women, obese subjects, those with longer diabetes duration and multiple complications showed a worse quality of life in all of the four areas of the WHO-WBQ. In Type 2 diabetic subjects, SF-36 scores, but not WHO-WBQ scores, were able to discriminate the population according to the treatment modalities. Lower levels of treatment satisfaction were related to female gender, longer diabetes duration, insulin treatment, presence of diabetes complications and HbA1c levels >7.0%. The flexibility of the treatement was perceived as a major problem even among patients treated with oral agents. CONCLUSIONS: The WHO-DTSQ can be considered as a valuable instrument to be used internationally for the description of diabetes treatment satisfaction. The WHO-WBQ also shows adequate psychometric properties, but additional data are needed to clarify whether it is more sensitive than SF-36, the most widely used generic instrument.

Adeno-associated viral vector-mediated human vascular endothelial growth factor gene transfer stimulates angiogenesis and wound healing in the genetically diabetic mouse.

AIMS/HYPOTHESIS: We studied the gene therapy efficacy of diabetes-associated wound healing disorder with an adeno-associated virus (AAV) vector expressing the 165-amino acid isoform of human vascular endothelial growth factor-A (VEGF-A) by using an incisional skin-wound model produced on the back of female diabetic C57BL/KsJ db+/db+ mice and their normal littermates ( db+/+m). METHODS: Animals were randomized to receive intradermally into the wound edges either rAAV-LacZ (a control gene), or rAAV-VEGF165. Animals were killed on different days (7 and 14 days after skin injury) and wounded skin tissues were used for gene marker studies, histological evaluation and immunohistochemistry, and wound breaking strength analysis. Furthermore we studied the VEGF mature protein in the wounds. RESULTS: We found that AAV vectors are highly efficient for gene transfer to the mouse skin, displaying an exquisite tropism for the panniculus carnosus by using the beta-galactosidase activity assay. We confirmed the increased expression of the angiogenic factor at day 7 by measuring the wound content of the mature protein. Delivery of VEGF165 to incisional skin wounds of diabetic mice resulted in a remarkable induction of new vessel formation with consequent improvement in the wound healing process. The rAAV-VEGF165 gene improved wound healing in diabetic mice through the stimulation of angiogenesis, reepithelization, synthesis and maturation of extracellular matrix. Moreover the recombinant AAV encoding the human VEGF165 increased the breaking strength of the wound and enhanced the wound content of VEGF. CONCLUSION/INTERPRETATION: Our study suggests that VEGF gene transfer might represent a new approach to treat wound healing disorders associated with diabetes.

Natural history of glucose tolerance, beta-cell function and peripheral insulin sensitivity in cystic fibrosis patients with fasting euglycemia.

OBJECTIVE: The loss of pancreatic beta-cells is thought to be one of the principal causes of diabetes mellitus (DM) in cystic fibrosis (CF), but the role of peripheral insulin resistance (IR) in the pathogenesis of DM in CF remains unclear. The aim of this study was to evaluate whether eventual changes of glucose tolerance (GT) over time were associated with modifications of insulin secretion or sensitivity. METHODS: Plasma glucose and insulin responses to an oral GT test (OGTT) were investigated and reinvestigated 13 Years later in 14 CF patients with initial and persistent fasting euglycemia and no history of insulin treatment. Insulin sensitivity (IS) at both tests was assessed on the basis of insulin and glucose levels both in the fasting state and during OGTTs. RESULTS: From the 1st to the 2nd OGTT: (a) the prevalence of DM responses significantly increased; (b) the areas beneath the respective glucose and insulin curves significantly increased and decreased respectively; (c) IR and IS indices decreased and increased respectively, even in the patients who developed DM; (d) pulmonary function significantly worsened in the entire series, especially in the patients who developed DM. CONCLUSIONS: (i) the natural history of glyco-metabolic status in CF is characterized by deteriorating GT over time; (ii) insulinopenia plays a prominent role in the pathogenesis of GT worsening; (iii) IR does not play any significant part in the pathogenesis of DM development; (iv) deterioration of lung function tests is more severe in the subjects who develop DM over time.

Oxidative stress causes nuclear factor-kappaB activation in acute hypovolemic hemorrhagic shock.

Nuclear Factor kappaB (NFkappaB) is an ubiquitous rapid response transcription factor involved in inflammatory reactions and exerts its action by expressing cytokines, chemokines, and cell adhesion molecules. We investigated the role of NF-kappaB in acute hypovolemic hemorrhagic (Hem) shock. Hem shock was induced in male anesthetized rats by intermittently withdrawing blood from an iliac catheter over a period of 20 min (bleeding period) until mean arterial blood pressure (MAP) fell and stabilized within the range of 20-30 mmHg. Hemorrhagic shocked rats died in 26.3 +/- 2.1 min following the discontinuance of bleeding, experienced a marked hypotension (mean arterial blood pressure = 20-30 mmHg) and had enhanced plasma levels of Tumor Necrosis Factor-alpha (200 +/- 15 pg/ml, 20 min after the end of bleeding). Furthermore, aortas taken 20 min after bleeding from hemorrhagic shocked rats showed a marked hypo-reactivity to phenylephrine (PE; 1nM to 10 microM) compared with aortas harvested from sham shocked rats. Hem shocked rats also had increased levels of TNF-alpha mRNA in the liver (15-20 min after the end of bleeding) and enhanced plasma levels of 2,5-dihydroxybenzoic acid (2,5-DHBA; 6 +/- 2.2 microm), 2,3-dihydroxybenzoic acid (2,3-DHBA; 13 +/- 2.1 microm), both studied to evaluate OH(*) production. Electrophoretic mobility shift assay showed that liver NF-kappaB binding activity increased in the nucleus 10 min after the end of hemorrhage and remained elevated until the death of animals. Western blot analysis suggested that the levels of inhibitory IkappaBalpha protein in the cytoplasm became decreased at 5 min after the end of bleeding. IRFI-042, a vitamin E analogue (20 mg/kg intraperitoneally 2 min after the end of bleeding), inhibited the loss of IkappaBalpha protein from the cytoplasm and blunted the increase in NF-kappaB binding activity. Furthermore IRFI-042 increased survival time (117.8 +/- 6.51 min; p <.01) and survival rate (vehicle = 0% and IRFI-042 = 80%, at 120 min after the end of bleeding), reverted the marked hypotension, decreased liver mRNA for TNF-alpha, reduced plasma TNF-alpha (21 +/- 4.3 pg/ml), and restored to control values the hypo-reactivity to PE. Our results suggest that acute blood loss (50% of the estimated total blood volume over a period of 20 min) causes early activation of NF-kappaB, likely through an increased production of reactive oxygen species. This experiment indicates that NF-kappaB-triggered inflammatory cascade becomes early activated during acute hemorrhage even in the absence of resuscitation procedures.

Association of the Sst-I polymorphism at the APOC3 gene locus with variations in lipid levels, lipoprotein subclass profiles and coronary heart disease risk: the Framingham offspring study.

Apolipoprotein (apo) CIII participates in the regulation of the metabolism of triglyceride-rich lipoproteins and it is a major component of chylomicrons and VLDL. The APOC3 gene is on chromosome 11q23 and is highly polymorphic. The less common allele (S2) of the SstI polymorphism on the 3' untranslated region of the APOC3 gene has been previously associated with increased triglycerides, total cholesterol (TC), and apoCIII levels and cardiovascular risk on several, but not all, studies. The aim of this study was to examine the association of this polymorphism with plasma lipid levels, lipoprotein subfractions and coronary heart disease (CHD) risk in a population-based study: The Framingham Offspring Study. The frequency of the S2 allele was 0.086, consistent with previous reports in Caucasian populations. In men, the S2 allele was associated with lower concentrations of high-density lipoprotein cholesterol (HDL-C; P<0.04) and HDL2-C (P<0.02) and a significant increase in apoCIII non-HDL (P<0.05). TG levels were higher in men carriers of the S2 allele, but this association did not reach statistical significance (P=0.30). Conversely, in women, the S2 allele was associated with increased TC (P<0.03), low-density lipoprotein cholesterol (LDL-C; P<0.03), and ApoB levels (P<0.04). Lipoproteins subfractions were also examined using nuclear magnetic resonance (NMR) spectroscopy. S2 male carriers had significantly lower concentrations of large LDL and a significant reduction in LDL particle size (P<0.04). In women, there was a significant increase in intermediate LDL particles (P<0.05) with no significant effect on lipoprotein diameters. We also examined the associations between the S2 allele and biochemical markers of glucose metabolism. In men, the S2 allele was associated with elevated fasting insulin concentrations (P<0.04), whereas no significant associations were observed in women. Despite the described associations with lipid and glucose metabolism related risk factors, we did not find any significant increase in CHD risk associated with the S2 allele in this population.

Regular moderate intensity physical activity and blood concentrations of endogenous anabolic hormones and thyroid hormones in aging men.

BACKGROUND: Physical activity has been reported to affect endocrine function in elderly men. OBJECTIVE: To establish an association between regular moderate physical activity and endogenous anabolic hormone levels in healthy aging men. PARTICIPANTS: Twenty four middle-aged (57.4+/-4.7 years) and 24 elderly (68.3+/-2.6 years) physically active men who in the past 10 years had been regularly bicycling during leisure time were compared with 24 middle-aged (57.9+/-4.0 years) and 24 elderly (67.2+/-1.7 years) sedentary men. Groups did not differ for body composition. MEASUREMENTS: Serum dehydroepiandrosterone sulfate (DHEAS), insulin-like growth factor-I (IGF-1), free testosterone (FT), and thyroid hormone levels were assessed. RESULTS: In general, elderly men had lower IGF-1 (P<0.001), DHEAS (P=0.013), and triodothyronine levels (P<0.001) than their middle-aged counterparts. Independently of age, however, physically active men had on average higher IGF-1 (P=0.031), DHEAS (P=0.001), and triodothyronine serum levels (P<0.001) than sedentary men. FT and thyroid stimulating hormone (TSH) serum concentrations did not differ across age groups, but physically active men had lower TSH values than sedentary men (P=0.021). CONCLUSIONS: Our results suggest that, in aging men, regular moderate physical activity is associated with higher levels of IGF-1 and DHEAS levels and with thyroid function alterations.
