ABSTRACT
BACKGROUND: Active and Environmental Tobacco Smoke (ETS) are a global cause of death. Osteoporosis (Op) is the most common metabolic bone disorder worldwide, impacting on mortality and disability, with high health and welfare costs. Active smoking is a known risk factor for Op, but there is few information regarding Op and ETS in men. PURPOSE: The study aim is to evaluate the association between smoking habits and Op in community-dwelling men that have been subjected to Dual-X-ray Absorptiometry and completed a questionnaire about their own and cohabiter's smoking habits. METHODS: We performed a cross-sectional study based on administrative data. This study is part of the SIMON protocol. The binary logistic regression analysis was used to estimate the role of ETS on the risk of Op, adjusting for age, body mass index (BMI), type 2 diabetes mellitus (T2DM) and eGFR. RESULTS: Four hundred sixteen men were selected and, based on questionnaire replies, 167 were classified as current smokers (CS), 93 as passive smokers (PS) and 156 as never smokers (NS). NS showed a lower prevalence of past fragility fracture, radiological features of osteoporosis and hypovitaminosis D compared to PS and CS (p < 0.05). NS showed a lower prevalence of Op compared to PS and CS, also after correction for age, BMI, T2DM and eGFR (p < 0.05). CONCLUSION: The study results demonstrate that PS and CS have a higher risk of Op, fragility fractures and vitamin D deficiency compared to NS.
ABSTRACT
PURPOSE: Current smoking is a risk factor for osteoporosis (Op), but few data are available regarding the passive smoke impact on Op susceptibility. This cross-sectional study aimed to evaluate the association between the smoking habits and Op in community-dwelling women undergoing dual-energy X-ray absorptiometry (DXA). METHODS: On 01/06/2018, general practitioners from "COMEGEN" Medical Cooperative, Naples, Italy, selected the medical records from the last 10 years of women who had a measurement of bone mineral density performed and simultaneously completed a questionnaire about their smoking behaviour and their cohabiters'. The binary logistic regression analysis was used to estimate the role of passive smoke on the risk of Op, adjusting for age and body mass index (BMI). RESULTS: Among 10,616 subjects, 3942 were currently smokers [CS; mean age 69.4 ± 10.4 years; BMI 27.0 ± 4.9 kg/m2], 873 were passive smokers (PS; mean age 67.8 ± 11.6 years; BMI 27.0 ± 4.9 kg/m2) and 5781 were never smokers (NS; mean age 67.8 ± 11.6 years; body mass index (BMI) 27.0 ± 4.9 kg/m2). Of all, 8562 women (mean age 70.3 ± 10.2 yrs; BMI 27.0 ± 4.9 kg/m2) received the Op diagnosis. PS showed an increased Op risk compared to NS [odds ratio (OR) 1.38 (1.14-1.67)] and comparable to CS [OR 1.02 (0.84-1.24)]. CONCLUSION: The study results demonstrate an association between passive smoke and Op in community-dwelling women already presenting with susceptibility to Op according to Italian essential assistance levels, suggesting that passive and active smoke are equivalent Op risk factors in women.

The latest European Guidelines of Arterial Hypertension have officially introduced uric acid evaluation among the cardiovascular risk factors that should be evaluated in order to stratify patient's risk. In fact, it has been extensively evaluated and demonstrated to be an independent predictor not only of all-cause and cardiovascular mortality, but also of myocardial infraction, stroke and heart failure. Despite the large number of studies on this topic, an important open question that still need to be answered is the identification of a cardiovascular uric acid cut-off value. The actual hyperuricemia cut-off (> 6 mg/dL in women and 7 mg/dL in men) is principally based on the saturation point of uric acid but previous evidence suggests that the negative impact of cardiovascular system could occur also at lower levels. In this context, the Working Group on uric acid and CV risk of the Italian Society of Hypertension has designed the Uric acid Right for heArt Health project. The primary objective of this project is to define the level of uricemia above which the independent risk of CV disease may increase in a significantly manner. In this review we will summarize the first results obtained and describe the further planned analysis.

OBJECTIVE: Recurrent respiratory papillomatosis (RRP) is characterized by exophytic, benign, and papillary lesions infected by the virus in the epithelium of the upper aerodigestive tract. RRP is caused by persistent infection of the respiratory epithelium by human papillomavirus (HPV) HPV6 and-11. The clinical course of RRP is unpredictable, frequently relapsing, and may be lifelong. The aim of this study is to evaluate the efficacy and safety of the use of intralesional Cidofovir in the treatment of RRP. PATIENTS AND METHODS: We have selected articles on the use of cidofovir as adjuvant therapy in laryngeal papillomatosis. We reviewed 20 reports that enrolled 185 patients with "adult onset recurrent respiratory papillomatosis" (AORRP) and 85 patients with "juvenile onset recurrent respiratory papillomatosis" (JORRP). We evaluated concentration of cidofovir, number of injections, injection interval, therapeutic response, side effects, and progression to dysplasia. RESULTS: The mean concentration of cidofovir was 7.5 mg/ml at injection. The mean number of injections per patient is 6 with 26 days between injections. The percentage of patients with dysplasia after use of cidofovir is 1.48%. The AORRP response to cidofovir is better with a 74% complete response rate, compared to 56.5% of the JORRP. CONCLUSIONS: Intralesion use of cidofovir has a good adjuvant action in RRP increasing the complete remission of the disease. The treatment does not increase the risk of laryngeal dysplasia.

PURPOSE: Leptin is associated with cardiovascular risk factors (e.g. hypertension, insulin resistance, kidney disease and excess body weight). Experimental studies showed that leptin might affect serum uric acid, by modulation of the uric acid excretion. However, there are few observational data on the relationship between leptin and uric acid in the general population. Therefore, the aim of the present study was to evaluate the relationship between leptin and uric acid and its excretion in a large middle-aged male general population. METHODS: A sample of 930 adult male individuals (mean age: 52 years) without therapy for high uric acid was included in the analysis (the Olivetti Heart Study). RESULTS: Uric acid was significantly and positively associated with blood pressure, BMI, waist circumference, insulin resistance, C-reactive protein and leptin (p < 0.01), while inversely with renal function (p = 0.01). The multivariate analysis confirmed the association between leptin and uric acid after adjustment for potential confounders (p < 0.01). After division for adiposity, this trend was confirmed separately for normal weight and excess body weight participants. Moreover, leptin was inversely associated with excretion of uric acid (p < 0.01), also in multivariate analysis (p = 0.03). CONCLUSION: The results of this study indicate a positive association between circulating leptin levels and uric acid, independently of potential confounders, both in normal and excess body weight men. Furthermore, an inverse association between leptin and uric acid excretion was detected.

BACKGROUND AND AIMS: Leptin (LPT) is associated with unfavourable cardio-metabolic risk profile. Although a number of studies have found a positive association between LPT and insulin resistance (IR), no observational study has evaluated a prospective association to detect a predictive role of LPT in IR. Therefore, the aim of this study was to estimate the role of LPT on the incidence of IR in an 8-year follow-up of a sample of adult men (The Olivetti Heart Study). METHODS AND RESULTS: The study included 527 not diabetic men without IR (homeostasis model assessment - HOMA index < 2.77 UI) at baseline. Baseline LPT was significantly and positively associated with HOMA index, body mass index (BMI), waist circumference and blood pressure. At the end of the 8-year follow-up period, a positive and significant association was detected between baseline LPT and changes in HOMA index (r = 0.25, p < 0.01) and incidence of IR (OR: 2.6, 95%CI: 1.9-3.4). This trend was also confirmed after adjustment for potential confounders. In addition, the predictive value of LPT was found in subjects who had not experienced any weight increase over the years, and for normal weight and excess body weight participants, separately. CONCLUSIONS: The results of this prospective study suggest a predictive role of circulating LPT levels on a reduction of insulin sensitivity over time, independently of main potential confounders, in non-diabetic men without IR at baseline. In addition, in normal weight individuals, LPT levels were associated with development of IR.

BACKGROUND/OBJECTIVES: The aim of the present study was to validate a short questionnaire on habitual dietary salt intake, to quickly and easily identify individuals whose salt consumption exceeds recommended levels. SUBJECTS/METHODS: A total of 1131 hypertensive subjects participating in the MINISAL-SIIA study were included in the analysis. Anthropometric indexes, blood pressure, and 24-h urinary sodium excretion (NaU) were measured. A fixed-sequence questionnaire on dietary salt intake was administered. RESULTS: NaU was significantly associated with scores, with a linear association across categories (p for trend <0.0001). In addition, participants who achieved a total score above the median value (eight points) had significantly higher NaU than those whose score was below median (p < 0.0001). In the total sample, the prevalence of "high NaU" (NaU > 85 mmol/day) and "very high NaU" (NaU > 170 mmol/day) was 86 and 35%, respectively. The score of the questionnaire had a significant ability to detect both "high NaU"-with a specificity of 95% at the score of 10 points-and "very high NaU"-with a specificity of 99.6% at score of 13 points. CONCLUSIONS: The main results of the study indicates that a higher score of this short questionnaire is distinctive of habitual high salt consumption in hypertensive patients.

BACKGROUND: Obstructive sleep apnoea (OSA) is a common disorder that may affect at least 2 to 4% of the adult population. Nasal-Continuous Positive Airway Pressure (N-CPAP) is today considered the gold standard for the treatment of OSA. The development of oral appliances (OAs) represents a new approach for the management of this pathology. The aim of this systematic review is to compare the efficacy of OAs and N-CPAP in the treatment of patients with mild to severe OSA. MATERIAL AND METHODS: A PubMed-MEDLINE and Cochrane databases search of articles published between 1982 and 2016 comparing the effect of N-CPAP and OAs in OSA patients was conducted during July 2016. The studies were selected and stratified according to PRISMA and SORT criteria. The main outcome measure was post-treatment Apnoea-Hypopnoea Index (AHI) while secondary outcomes included post-treatment Epworth Score Scale (ESS) score and lowest Oxygen Saturation level. RESULTS: N-CPAP was significantly more effective in suppressing AHI than OA. Moreover, N- CPAP was significantly more effective in increasing post-treatment lowest Oxygen Saturation level than OA. However, no significant different in decreasing ESS values was found between the two treatments. CONCLUSIONS: On the basis of evidence in this review it would appear appropriate to offer OA therapy to those who are unwilling or unable to persist with CPAP therapy. N-CPAP still must be considered the gold standard treatment for OSA and, therefore, OAs may be included in the list of alternative options.

BACKGROUND: P53, a crucial suppressor of tumor formation, generates multiple isoforms, whose role in disease is still being defined. METHODS: By immunohistochemistry, we studied the expression of P53 protein and relative isoforms in benign papillomas (PA, n=9), inverted papilloma (IPA, n=10) and squamous cell carcinomas (SCC, n=21). RESULTS: In all lesions, P53 isoforms were significantly more expressed than P53. Immunoexpression of P53 matched with P53 isoforms in IPA as well as in SCC. Simultaneous immunoexpression of P53 and related isoforms was double in SCC compared to IPA (10% vs 24%), while expression of P53 isoforms was strongly reduced (70% vs 43%). IPA showed the highest percentage of both reactive cases and immunostained cells expressing P53 isoforms. CONCLUSIONS: We found the higher expression of P53 isoforms in IPA and SCC compared to PA, suggesting their role in local aggressiveness and malignant proliferation in head-neck lesions.

The role of cVEMPs and vHIT in the evaluation of otosclerosis and its eventual vestibular impairment: preliminary findings. OBJECTIVES: Otosclerosis is one of the most common causes of hearing loss in adults, with a prevalence of 0.3% to 0.4% in Caucasians. Vestibular symptoms may occur, with an incidence ranging between 5% and 57% of patients. The aim of our study is to evaluate the vestibular function and its eventual changes after stapes surgery in patients affected by otosclerosis. METHODS: Prospective case-control study. Twenty patients (17 females; age range 33-58; mean age 44) who underwent surgery for otosclerotic disease between April 2012 and February 2014 were prospectively studied. These patients underwent preoperative and postoperative audiological tests. Furthermore, vestibular function was evaluated using the cervical evoked myogenic potentials test (cVEMPs) and video head impulse test (vHIT), preoperatively and postoperatively. A case-control study was also performed. Quantitative and statistical analysis of patients' vestibular function was carried out both before and after stapes surgery. RESULTS: The means of the vHIT gains in the case group were 1.03 on the right side and 1.01 on the left side. A significant difference between case and control groups was seen, with a lower left gain registered in the control group. No cases with a gain of less than 0.8 were found in either group. Moreover, a significant postoperative reduction in P1/NI amplitude was seen in patients complaining of postoperative dizziness or vertigo. CONCLUSIONS: These findings indicate a probable traumatic saccular impairment in patients with vestibular symptoms. However, a longer follow-up may help in understanding the behaviour of cVEMPs in post-stapes surgery vertigo.

BACKGROUND AND AIMS: Recently, some studies have indicated that a new anthropometric index, body adiposity index (BAI), could be more strongly correlated with the percentage of body fat than BMI. However, the results on its role in predicting cardiovascular risk were not univocal. Therefore, the aim of our study was to compare the predictive role of BMI and BAI on risk of hypertension (HP), blood pressure (BP) changes, and subclinical organ damage after an 8-year follow-up, in a sample of adult men participating in the Olivetti Heart Study. METHODS AND RESULTS: Participants were 350 untreated normotensive men without diabetes, examined twice at baseline (1994-95) and after 8 years of follow-up [2002-04]. BMI was expressed as kg/m(2). BAI was calculated according to the following formula: [(hip circumference (cm)/height(1.5) (m)) - 18]. Subclinical organ damage was detected by urinary albumin excretion (UAE) and left ventricular mass, evaluated by the Cornell product (CP). At baseline, BAI and BMI were both associated with diastolic blood pressure (DBP) and mean arterial pressure (MAP). After 8 years, both baseline BAI and BMI were associated with changes (Δ) in systolic BP, MAP and pulse pressure, while only BMI was also positively related to ΔDBP. Analysis of HP incidence showed that both indices were significant predictors of HP. In addition, both BAI and BMI were significantly associated with ΔUAE, but not with ΔCP. Analysis of the changes in BAI and BMI confirmed these results, as the two indices were significantly associated with risk of HP and changes in BP and UAE, but not with changes in CP. CONCLUSIONS: In this sample of healthy adult men, BAI and BMI were significant predictors of risk of HP and changes in BP, after an 8-years follow-up. In addition both indices predicted UAE changes, but neither was associated with the CP changes.

OBJECTIVE: Olfactory dysfunction is a possible side effect of chemo-radiotherapy performed in patients affected by nasopharyngeal carcinoma. Self-rating measurements and olfactory event-related potentials were used and compared in order to evaluate the impact of this treatment on the olfactory system. METHODS: Nine patients underwent subjective evaluation of olfactory function (using visual analogue scales for olfactory symptoms and quality of life, and a six-item Hyposmia Rating Scale), and a quantitative and objective measurement (olfactory event-related potentials). RESULTS: Spearman's rank correlation analyses highlighted significant relationships between the clinical scales and olfactory event-related potentials. Inter-group analyses showed significant differences in the latency and in the amplitude of olfactory event-related potentials between patients and controls. CONCLUSION: Taking into account the small sample size and the lack of pre-treatment assessment, olfactory event-related potentials seemed to allow a more objective diagnosis of unilateral and bilateral olfactory loss. Moreover, olfactory event-related potentials and subjective scales results were concordant.

The aim of this study was to detect the prevalence of resistant hypertension (RH), allowing for adherence to appropriate lifestyle measures according to European Society of Hypertension-European Society of Cardiology (ESH-ESC) 2013 guidelines, in a sample of 1284 hypertensive subjects participating at the MINISAL-SIIA study. Hypertensive patients were recruited in 47 Italian centres, recognised by the Italian Society of Hypertension. Anthropometric indexes, blood pressure and 24-h urinary sodium (Na24h) and potassium (K24h) excretion were measured. Data on antihypertensive therapy were available for 1177 (92%) subjects. The population was divided into three groups (North, Central and South), according to their geographical location. Accounting only at the treatment criteria, the prevalence of RH was 8.2% (96/1177). RH prevalence in the southern, central and northern regions was respectively: 1, 3.8 and 3.3% (P<0.001). Participants with RH were older and showed a higher body mass index (BMI) and waist circumference compared with other subjects (P<0.005). RH risk was statistically significant (P<0.01) increased of 1.52-fold (95% confidence interval (CI):1.20-1.92) for one unit increase in s.d. score of age (11 years), and 1.50-fold (95% CI:1.22-1.83) for one unit increase in s.d. score of BMI (4.5 kg m-2). Including in RH diagnosis also the adherence to appropriate lifestyle measures, such as dietary salt restriction (Na24h <100 mmol) and normal BMI (18-25 kg m-2), RH prevalence felt respectively to 2.2% (26/1177) and 0.8% (9/1177). In conclusion in this national sample of Italian hypertensive population, among participants following both drug treatment and lifestyle modifications advises, the 'true' RH prevalence appears to be particularly low.

Subannular T-tubes for the treatment of adhesive otitis: how we do it. OBJECTIVES: Adhesive otitis is a chronic otitis media (OM) that consists of the adhesion of the tympanic membrane (TM) to the promontory. The aim of our study is to evaluate a new way of positioning subannular T-tubes (SATs) in patients affected by adhesive otitis. METHODOLOGY: This study enrolled 22 patients (average age: 36.7 yo, 2.5 SD; M/F ratio: 14/8) affected by unilateral chronic adhesive otitis. All of the patients underwent the positioning of a SAT and a Silastic@ sheet in the tympanic cavity. The clinical course was evaluated, considering otoscopic and audiological variations. RESULTS: In our series, only one case of extrusion of tubes with residual perforation of TM was recorded. Auditory outcomes were satisfying in 18/22 patients (81.8%). CONCLUSIONS: The proposed addition of a Silastic disk seems to avoid a new adhesion of the tympanic membrane to the promontory and, therefore, prevents treatment failures. A longer follow-up and a larger case series are needed to prove the efficacy of this surgical variation. Finally, the positioning of SATs can be considered as a valid and safe procedure for the treatment of adhesive otitis.

Simple nodular goiter and Hashimoto's thyroiditis are 2 frequent nonmalignant thyroid diseases. Tobacco smoking has detrimental effects on the endocrine system and in particular on thyroid function and morphology. The objective of this cross-sectional study, involving 1800 Caucasian adults from a geographical area with mild iodine deficiency, was to evaluate the relationship between tobacco smoking, smoking cessation, and the prevalence of simple nodular goiter and Hashimoto's thyroiditis. Thyroid status was evaluated by ultrasonic exploration of the neck, measurement of FT3, FT4, TSH, antibodies against thyroid peroxidase and thyroglobulin, and urinary iodine excretion. The fine-needle aspiration biopsy of significant nodules was also performed. Smoking habits were evaluated by a specific questionnaire and the calculation of number of pack years. Both current and previous smokers showed an increased risk of simple nodular goiter compared to never smokers after adjustment for potential confounders and known goitrogen factors. Interestingly, the simple nodular goiter risk was similar for never smokers and for previous smokers declaring a time since cessation of smoking for more than 69 months. Smoking habit was not associated to an increased risk of Hashimoto's thyroiditis.Smoking appears to be an independent risk factor for simple nodular goiter but not for Hashimoto's thyroiditis in an area with mild iodine deficiency. A prolonged withdrawal of smoking dramatically reduces the risk of simple nodular goiter occurrence.

OBJECTIVE: To evaluate seizures as first clinical manifestation of brain arteriovenous malformations (AVMs), in relation to angioarchitectural features of these vascular anomalies. METHODS: We performed a prospective observational study, collecting records of patients with AVMs consecutively admitted to the Neurological and Neurosurgery Units of Perugia University and to the Neurosurgery Unit of Terni Hospital, during a 10-year period (1 January 2002 to 1 June 2012). Two groups of patients, with or without seizures as AVM first presentation, were analysed to identify differences in demographic and angiographic features. A multivariate logistic regression model was also developed. RESULTS: We examined 101 patients with AVMs, 55 male and 46 female. Seizures were the initial clinical manifestation in 31 (30.7%) patients. We found a significant difference (p<0.05) between two groups of patients, with or without seizures as AVM first presentation concerning location, side, topography and venous drainage. A multivariate logistic regression model showed that clinical presentation with seizures was correlated with a location in the temporal and frontal lobes, and with a superficial topography. The strongest association (OR 3.48; 95% CI 1.77 to 6.85) was observed between seizures and AVM location in the temporal lobe. CONCLUSIONS: Vascular remodelling and haemodynamic changes of AVMs might create conditions for epileptogenesis. However, here we show that malformations with specific angiographic characteristics are more likely to be associated with seizures as first clinical presentation. Location is the most important feature related to epilepsy and in particular the temporal lobe might play a crucial role in the occurrence of seizure.

OBJECTIVE: As excess sodium and inadequate potassium intake are causally related to hypertension and cardiovascular disease, the MINISAL-GIRCSI Program aimed to provide reliable estimates of dietary sodium and potassium intake in representative samples of the Italian population. DESIGN AND METHODS: Random samples of adult population were collected from 12 Italian regions, including 1168 men and 1112 women aged 35-79 yrs. Electrolyte intake was estimated from 24 hour urine collections and creatinine was measured to estimate the accuracy of the collection. Anthropometric indices were measured with standardised procedures. RESULTS: The average sodium excretion was 189 mmol (or 10.9 g of salt/day) among men and 147 mmol (or 8.5 g) among women (range 27-472 and 36-471 mmol, respectively). Ninety-seven % of men and 87% of women had a consumption higher than the WHO recommended target of 5g/day. The 24 h average potassium excretion was 63 and 55 mmol, respectively (range 17-171 and 20-126 mmol), 96% of men and 99% of women having an intake lower than 100 mmol/day (European and American guideline recommendation). The mean sodium/potassium ratio was 3.1 and 2.8 respectively, i.e. over threefold greater than the desirable level of 0.85. The highest sodium intake was observed in Southern regions. Sodium and potassium excretion were both progressively higher the higher the BMI (p < 0.0001). CONCLUSIONS: These MINISAL preliminary results indicate that in all the Italian regions thus far surveyed dietary sodium intake was largely higher and potassium intake lower than the recommended intakes. They also highlight the critical association between overweight and excess salt intake.

Excess dietary sodium chloride (salt) intake is etiologically related to hypertension and cardiovascular disease (CVD). Moderate reduction of salt intake reduces blood pressure (BP) and is expected to contribute to reduce the risk of CVD. Previous community-based trials to reduce BP by means of salt reduction were very successful. The initial positive results of national strategies of dietary salt intake reduction in several European countries, driven by the initiative of the World Health Organisation (WHO) and non-governmental organisations such as the World Action of Salt and Health (WASH), have paved the way for action in other European Union (EU) member states. In Italy, several initiatives aiming at reduction of salt intake at the population level have been recently undertaken. These initiatives include i) the evaluation of current dietary habits promoted by the Working Group for Dietary Salt Reduction in Italy (GIRCSI); ii) the chemical analysis of the bread salt content, a major source of sodium intake in Italy, and the agreement between the bakers' associations and the Ministry of Health for a gradual reduction of the bread salt content; iii) the implementation of educational campaigns to increase population awareness, iv) the involvement of the food catering system. In the immediate future, food reformulation must be extended to other food categories in collaboration with industry, foods' salt targets ought to be defined, the food labelling system must be improved and population salt awareness must be further increased through educational campaigns. The GIRCSI Working Group is committed to pursue these objectives.

BACKGROUND AND AIM: High leptin (LPT) is associated with high blood pressure (BP), insulin resistance and systemic inflammation but also excess body weight and adiposity. To disentangle these multiple relations, we analyzed BP, HOMA and circulating C-reactive protein concentration (hs-CRP) in white male adults with different LPT levels but similar age, body mass index (BMI) and body fat distribution. The novel aspect is the different statistical approach used to investigate the relation between LPT and the other alterations present in obesity. METHODS AND RESULTS: 972 Olivetti Heart Study participants were stratified according to the median LPT distribution (2.97 ng/ml) into low LPT (l-LPT) and high LPT (h-LPT). The two groups were then carefully matched for age and BMI. We identified two groups of 207 h-LPT and 207 l-LPT individuals with overlapping age, BMI and waist/hip ratio. The two groups had different BP (132.9 ± 16.2/85.7 ± 9.0 vs 128.7 ± 18.2/82.8 ± 9.8 mmHg, p = 0.014 for SBP and p = 0.002 for DBP) and prevalence of hypertension (57% vs 43%, p = 0.027). Upon separate evaluation of untreated individuals with BMI < 25 or BMI ≥ 25, within the latter subgroup h-LPT compared with l-LPT participants (n = 133 each group) had higher BP (p = 0.0001), HOMA index (p = 0.013), hs-CRP (p = 0.002) and heart rate (p = 0.008) despite similar age and BMI. By contrast, within the normal weight subgroup, h-LPT individuals did not differ from l-LPT (n = 37 each) for any of these variables. CONCLUSIONS: High LPT is associated with higher BP, HR, hs-CRP and HOMA index independently of BMI and fat distribution but only among overweight individuals.

BACKGROUND/OBJECTIVES: To assess dietary habitual sodium intake and the association between daily sodium intake and anthropometric indices, food habits and hypertension in the sample of adult male population participating in the Olivetti Heart Study. SUBJECTS/METHODS: The study population was composed of 940 men participating in the 2002-2004 follow-up examination of the Olivetti Heart Study. Blood pressure, anthropometric indices, biochemical parameters and sodium excretion in a 24-h urine collection were measured. The frequency of consumption of selected foods was estimated by a food frequency questionnaire (FFQ) capturing the previous year data. In a subgroup of the study population (n=138), the fractional excretion of sodium was estimated by endogenous lithium clearance. RESULTS: Dietary sodium intake estimated by 24 h urinary excretion was 203+/-70 mmol/day. Sodium excretion was significantly lower in treated hypertensive patients and higher in overweight/obese participants when compared with normotensive and normal-weight individuals, respectively. In addition, the inverse correlation detected in normal-weight individuals (r=-0.321; P<0.05) between fractional proximal tubular sodium reabsorption and dietary sodium intake was disrupted in overweight/obese individuals (r=0.058; P=NS). The independent determinants of 24 h urinary sodium excretion were body mass index (BMI), the occurrence of antihypertensive treatment, and frequency of consumption of pasta and cold cuts. CONCLUSIONS: Habitual salt intake in this sample of male adult population in southern Italy was well above the recommended amounts. A higher salt intake and an altered renal sodium handling were observed in overweight and obese participants. Sodium intake was only slightly reduced in hypertensive participants on pharmacological therapy.
