Apolipoprotein B and Lipid Profile in Italian Children and Adolescents.

RATIONALE: The prevention of cardiovascular (CV) disease is mandatory from childhood onwards. Among biochemical markers related to the clinical cardiovascular outcome, LDL cholesterol (LDL-C), non-HDL-C and apolipoprotein B (ApoB) are recognized as main target parameters. Emphasis on ApoB concentrations is growing, as representative of any class of atherogenic lipoprotein. This consideration allows checking of subjects under 18 years of age when the CV risk occurs. The aim of this study is to evaluate ApoB levels in a sample of Italian hyperlipidemic children and adolescents, and their siblings, to test any relationship with their lipid profile. METHODS: A retrospective study, including 1877 children and adolescents (aged 0-18 years), was performed. Clinical and biochemical data were selected from a database, including the lipid profile, ApoB analysis and anthropometric parameters of any proband. Participants had been checked as potentially hyperlipidemia affected, the suspicion raised by familial CV risk or because the dyslipidemia was already known. Data from the first visit at the University Hospitals in Rome and Turin were collected. Patients affected by secondary hyperlipidemia or obesity were excluded. Blood test analysis was performed in fasting conditions by automated commercial kits. Participants were classified according to gender, age (stratified in subgroups: 0-5, 6-10, 11-14, and 15-18 years old) and anthropometric parameters, referred to as weight in Kg and height in cm, and BMI calculated. Lipid profile results were stratified in relation to acceptable, borderline, or increased levels, as indicated by NCEP, and any potential relation with ApoB established. Statistics were performed by Epi-Info 7 programs to evaluate the variance analysis. Either parent could sign the informed consent. RESULTS: Among the whole sample n.1010 and n.867 participants were females and males, respectively. TC values acceptable (≤170 mg/dL), borderline (171-200 mg/dL) and elevated (≥201 mg/dL) were found in 411 (22%), 585 (31%) and 881 (47%) participants, respectively. The LDL-C cut-off considered was 110 mg/dL (90° percentile). Mean ApoB progressively increased from 65 to 110 mg/dL according to TC levels and resulted in significant correlation when any age subgroup and gender was considered. The highest ApoB values, TC and LDL-C related, were found in the youngest subgroup, regardless of gender. CONCLUSION: ApoB results increase progressively and in parallel with TC and LDL-C and represent a further parameter to distinguish between normal and hyperlipidemic subjects. Serum levels are close to 70 mg/dL and to 100 mg/dL in the former and latter group, respectively.

The Association between Mid-Upper Arm Circumference and Blood Pressure in an Italian Population of School-Aged Children and Adolescents with Lipid Disorders.

Background: Many anthropometric measurements have been investigated concerning their association with blood pressure (BP) in paediatric age groups. This study aims to find a relationship between mid-upper arm circumference (MUAC) and BP in a population of children and adolescents aged 1-18 years. Methods: 5853 subjects (2977 females and 2876 males) were studied. MUAC, body mass index (BMI), and BP were measured. The individuals in the study were subdivided and grouped by gender and type of school attended in Italy: 1-5 years (pre-school), 6-10 years (primary school), 11-13 years (secondary school), 14-18 years (high school). Results: In the age range of 6-13 years, all the subjects with MUAC > 50th percentile had systolic and diastolic BP significantly higher than children with MUAC below 50th percentile (p < 0.0001). In the age range 14-18 years, the relationship persisted only in females (p < 0.001 and p < 0.05 for diastolic and systolic BP, respectively). A linear relationship was found between MUAC and BMI. Conclusions: In Italian children of both genders aged 6-13, arm distribution of body fat is strongly associated with increased systolic and diastolic BP. As such, a simple anthropometric measurement like MUAC might represent a tool to identify young subjects who are at risk for HTN.

Masticatory Force in Relation with Age in Subjects with Full Permanent Dentition: A Cross-Sectional Study.

Masticatory performance is directly correlated with masticatory muscle work to grind and cut the food. Chewing efficacy is decisive to eating a variety of foods needed maintain general health status at all ages. Older people have oral problems that get worse with age. Elders have more pathologies such as periodontal diseases, caries, tooth loss and inadequate dental prostheses than younger subjects. OBJECTIVES: to investigate the correlation between masticatory bite force (MBF) and body mass index (BMI) vs. aging and sex. METHODS: This study was performed on 426 subjects (213 females plus 213 male) assigned into five different groups by age. Group "A" aged from 20 to 35 years; group "B" aged 45-59 years; group "C" aged 60-69 years; group "D" aged 70-79 years; and group "E" aged more than 79 years. RESULTS: There were not statistically significant differences in right-side MBF versus left-side MBF. The differences between sex were statistically significant with a stronger bite in males than females (p < 0.05). At the same time, younger subjects had a stronger bite than elders (p < 0.05). In group "E", more corpulent subjects (BMI > 25) had an MBF higher than less corpulent subjects (BMI < 25, p < 0.05). The analysis of mean MBF showed a statistically significant difference within all groups stratified by BMI with mean values inversely proportional with age (p < 0.001). CONCLUSION: The results in our study confirm data from many scientific papers. The importance of the present paper was to correlate data between and within a large sample with a wide range of ages. Our sample subjects had a 31%-33% decrease in MBF from group "A" to group "E" group, but they all had full permanent dentation and they preserved a valid MBF.

Lifestyle and awareness of cholesterol blood levels among 29159 community school children in Italy.

BACKGROUND AND AIM: Lifestyle habits including indoor and outdoor activities among community school children, adherence to the Mediterranean diet and awareness about total cholesterol blood levels represent determinant factors in cardiovascular disease (CVD) prevention. The aim of this study was to analyze the relationship between adherence to the Mediterranean diet, total cholesterol blood levels, body composition and hours per day spent in in-house or outdoor among 29,159 Italian 6-14 years-old community school children (50% boys). The KidMed questionnaire, modified to handle missing information on olive oil consumption, was used to assess the adherence to the Mediterranean diet among participants. METHODS AND RESULTS: Associations between variables were tested according to 3 classes of the Mediterranean diet adherence score using analysis of variance. Participants with high adherence to Mediterranean diet were few (1%). Overall awareness of total cholesterol blood levels was low among children (4.5%), slightly higher among parents (26.2 and 24.1% in mothers and fathers, respectively). Among Mediterranean diet adherent children, BMI was significantly (p < 0.001) smaller than among the non-Mediterranean or intermediate adherent children as were the total hours spent per day watching television or playing with videogames (p < 0.001) whereas the hours/day in sport or outdoor activities were more (p < 0.001). These results were confirmed by multiple linear regression with KidMed scored 0 to 8 as dependent variable. CONCLUSION: Although awareness of total cholesterol blood levels and adherence to the Mediterranean diet are rare among community school children, only among these a healthier lifestyle was practiced with a tendency to lower CVD risks. These results are important as the first sized experience of this type in Italy.

Echocolor Doppler morpho-functional study of the jugulo-subclavian confluence in chronic cerebro-spinal venous insufficiency and multiple sclerosis patients.

OBJECTIVES: The aim of this work is to measure the mean diameter of the confluence jugulo- subclavian, the impact of different types of jugular confluences and the correlation between the types of confluences and the Valsalva maneuver (jugular reflux) in subjects with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and Multiple Sclerosis. METHOD: We investigated by Echo-Color-Doppler (ECD) 103 subjects (67 F 36M) of mean age 45 ± 12 years (a minimum of 22 to a maximum of 79 years, with a median of 44 and a modal value 42 years), mean EDSS of 4.7 and average disease duration of 12 years. RESULTS: The 103 right jugular veins investigated had an average diameter of 8.4 ± 2.4 mm (minimum 4.0, maximum 14.9 mm; median 7.9; modal value 7.6 mm). Three form types were found: 56 cylindrical, 29 conical and 18 funnel. Valsalva maneuver was positive in 30 patients. The 103 left jugular investigated had an average diameter of 8.9 ± 2.4 mm (minimum 2.8, maximum 14.4 mm; median of 8.8; modal value 8.7 mm). The form types were found: 42 cylindrical, 45 conical and 16 funnel. Valsalva maneuver was positive in 30 patients. CONCLUSIONS: The mean diameter of the jugular veins was 8.7 mm. Internal jugular veins with cylindrical morphology have a diameter smaller than other forms; this difference is statistically significant. The different morphology of the jugular vein confluence does not increase the possibility of a reflux because the positive Valsalva maneuvers are not statistically significant when compared to the various types. KEY WORDS: CCSVI, EchoColorDoppler Map, Jugulo-Subclavian Confluence Diameter.

Venous compression syndrome of internal jugular veins prevalence in patients with multiple sclerosis and chronic cerebro-spinal venous insufficiency.

OBJECTIVES: Analysis of the incidence of Venous Compression Syndrome (VCS) with full block of the flow of the internal jugular veins (IJVs) in patients with Multiple Sclerosis and Chronic cerebro-spinal venous insufficiency. METHODS: We included 769 patients with MS and CCSVI (299 males, 470 females) and 210 controls without ms and ccsvi (92 males, 118 females). each subject was investigated by echo-color-doppler (ecd). morphological and hemodynamic ecd data were recorded by a computerized mem-net maps of epidemiological national observatory on ccsvi and they were analyzed by mem-net clinical analysis programs. RESULTS: VCS of IJVs occurs in 240 subjects affected by CCSVI and MS (31% of total) and in 12 controls (6% of total). The differences between the two groups are statistical significant (X² = 36.64, p<0.0001). CONCLUSION: Up to day there are no longitudinal studies that allow us to identify the WC of jugular and/or vertebral veins as etiology of a chronic neurodegenerative disease, but we note that Venous Compression Syndrome of IJVs is strongly associated with MS and CCSVI. KEY WORDS: Chronic Cerebro-Spinal Venous Insufficiency, Multiple Sclerosis, Venous Compression Syndrome.

Jugular diameter and venous reflux.

OBJECTIVES: Aims of this study were to investigate the prevalence of reflux on internal jugular veins(IJV) by Valsalva maneuver and to define the association between reflux of IJV in subjects with both CCSVI and MS. METHODS: We recruited 393 patients with MS and CCSVI. Study participants underwent EchoColor Doppler exam in order to define IJV diameter at confluence in subclavian (JSd). Subjects were divided in three groups: group "1

New acoustic wave therapy improves quality of life in patients with multiple sclerosis and chronic cerebrospinal venous insufficiency.

A Multiple Sclerosis patient with chronic cerebrospinal venous insufficiency (CCSVI) treated by acoustic waves, modulated in frequency and power of the Dreno-MAM® device, showed a progressive improvement in motor coordination, resistance to work, muscular power and rigidity, and distal microcirculation. Life quality, chronic fatigue, and clinical severity questionnaires EDSS show marked improvements with a follow-up of two years. We suggest that the method could be also used in the chronic fatigue syndrome and other neurological diseases such as Parkinson or Meniere syndrome. Analyses on statistically robust samples are in progress to validate such impressive result obtained by this nonpharmacological and non-invasive treatment.

C1-C2 X-Ray assessment of misalignment parameters in patients with Chronic Cerebra-spinal Venous Insufficiency and Multiple Sclerosis versus patients with other pathologies.

PURPOSE: The complete compression of the internal jugular veins, in front position, shows a prevalence of 48% and it is equally distributed in the various segments of these veins in patients with Chronic Cerebro-Spinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS). The aim of this search is to identify radiological dislocation of C1-C2 as specific markers in patients with CCSVI and Multiple Sclerosis (MS). METHOD: We investigated 386 patients suffering from CCSVI and Multiple Sclerosis and a control group of 156 patients without MS. RESULTS: The assessment of Anterior Intrusion shows the following average values: in the group with CCSVI and MS: 4.29 ±1.48 mm while in the control group: 3.78 ±1.45 mm (p = 0.0008).The evaluation of the Right Laterality shows the following average values: in group with CCSVI and MS: 2.31±1.41 mm, in control group: 1.97 ±1.28 mm (p = 0.0426). We found also that a longer duration of the disease corresponds to a higher severity of the pathological condition (p <0.0001). CONCLUSION: Data analysis of C1-C2 X-Ray parameters shows statistical significance of severe anterior intrusion and right laterality misalignment in the people with CCSVI and MS, that are two to three times more frequent as compared to controls. Considering the novelty of this work and the total absence of scientific similar works able to confirm this data, it is necessary to continue these studies in order to improve the clinical management of these patients and to perform therapeutic strategies based on venous decompressive treatments both surgical that manipulatives.

Preliminary results after upper cervical chiropractic care in patients with chronic cerebro-spinal venous insufficiency and multiple sclerosis.

PURPOSE: The aim of the study is to evaluate the clinical and X-ray results of the Upper Cervical Chiropractic care through the specific adjustments (corrections) of C1-C2 on patients with chronic venous cerebral-spinal insufficiency (CCSVI) and multiple sclerosis (MS). METHOD: We studied a sample of 77 patients before and after the Upper Cervical Chiropractic care, and we analyzed: A) The change of the X-ray parameters; B) The clinical results using a new set of questions. The protocol of the C1- C2 upper Cervical Chiropractic treatment, specific for these patients, lasts four months. From a haemodynamic point of view we divided the patients in 3 types: Type 1 - purely vascular with intravenous alterations; Type 2 - "mechanical" with of external venous compressions; Type 3 - mixed. RESULTS: We found an improvement in all kinds of subluxations after the treatment with respect to the pre-treatment X-ray evaluation, with a significant statistical difference. The differences between the clinical symptoms before and after the specific treatment of C1-C2 are statistically significant with p<0.001 according to the CHI-Square test revised by Yates. CONCLUSIONS: The preliminary X-ray and clinical improvements of the Upper Cervical Chiropractic corrections on C1- C2 on these patients with CCSVI and MS encourage us to continue with our studies. We believe that the Upper Cervical correction on C1-C2 could be the main non-invasive treatment of the CCSVI mechanical type in patients with MS. Further studies are required to evaluate the correlation between the Upper Cervical Chiropractic correction on C1-C2 on the cerebral venous drainage and the cerebro-spinal fluid.

Low dose chromium-polynicotinate or policosanol is effective in hypercholesterolemic children only in combination with glucomannan.

OBJECTIVE: A low-fat, fiber-rich diet is the first step in the management for hypercholesterolemic children. Glucomannan (GM) is a natural fiber that has been demonstrated to lower total and LDL-cholesterol. The use of high-dose chromium-polynicotinate (CP) and policosanol (PC) has also shown cholesterol-lowering benefits. We aimed at investigating the effects of low-dose CP or PC and their GM combination in hypercholesterolemic children. METHODS: A double-blind trial was conducted in 120 children (60 M, 60 F, 9 ± 4 years, median 9.6 years, range: 3-16 years) randomly assigned to 5 neutraceutical and 1 placebo (only resistant starch) 8-week treatment groups. Fasting blood glucose (FBG), total cholesterol (CholT), triglycerides (TG), HDL and LDL cholesterol were considered. RESULTS: GM combination of low-dose CP or PC reduced CholT and LDL without changing HDL, TG and FBG. The highest post-treatment changes were seen after GM combination with CP (CholT 85 ± 3% and LDL 85 ± 5%, of pretreatment) which was significantly (p < 0.01) less than with low-dose CP or PC and starch. When GM was associated with starch, there was no lipid lowering effect, which was an unexpected finding as compared to previous data with GM and no starch. No adverse effects were reported. CONCLUSION: This is the first report to show the cholesterol-lowering efficacy of GM combined treatment with low-dose CP or PC. Further studies are needed to investigate the best combinations and doses of nutraceutics to be added to the standard GM treatment. The potential negative association of GM and nutraceutics with starch is clearly shown.

Effect of dietary supplementation with glucomannan on plasma total cholesterol and low density lipoprotein cholesterol in hypercholesterolemic children.

AIM: This paper evaluates the effect of the adjunct of the hydrosoluble fiber glucomannan to a Step-One-Diet in 40 plasma hypercholesterolemic children, during a randomized controlled trial, to reduce plasma cholesterol. METHODS: All the subjects recruited underwent an 8-week run in diet period; a Step-One-Diet was prescribed. After that, they were randomly allocated to one of two groups: Step-One-Diet only (control), and Step-One-Diet plus glucomannan in gelatine capsules. After another 8 weeks of treatment, the results were compared within and between the two groups. RESULTS: Glucomannan treated group showed decreased values in plasma total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) vs. control group after 8 weeks of treatment. The percentage decrease showed a statistically significant difference between sex groups. Decreases were observed in favor of female vs. male children in TC (24% vs. 9%) and LDL-C (30% vs. 9%). CONCLUSIONS: These results suggest that glucomannan may represent a rationale adjunct to diet therapy in primary prevention in high risk hypercholesterolemic children.
