Patients With Heart Failure

Vitamin D deficiency is frequent among patients with heart failure (HF) and diabetes, disorders associated with exercise intolerance and muscle weakness. This study aims to search for associations between vitamin D sufficiency and physical function indexes in patients with HF and diabetes. A cross-sectional study of 146 HF patients, 39.7% with diabetes, at a Brazilian tertiary outpatient clinic was performed. Patients underwent clinical evaluation, 6-minute walk test (6 MWT), handgrip strength, physical activity level (IPAQ), and biochemical evaluations including serum 25-hydroxyvitamin D. Classification was done according to vitamin D status (≥30 ng/dL, sufficient) and presence/absence of diabetes in vitamin sufficient, no diabetes (DS-C,n=25), vitamin sufficient, diabetes (DS-DM,n=18), vitamin deficient, no diabetes (DD-C,n= 63), and vitamin deficient, diabetes (DD-DM,n=40). Patients age was 55.4 ± 8 yrs; 70.5% had vitamin D deficiency. Clinical characteristics were similar among groups. Total time expended in physical activity was similar among groups(P=0.26). DS-C covered higher distances in the 6 MWT (392 ± 60 m)versusDD-DM (309 ± 116 m);P=0.024. Handgrip strength was similar among groups but tended to lower levels in DD-DM(P=0.074)even after being adjusted to physical activity(P=0.069). Vitamin D deficiency can influence physical function in HF diabetic patients.

AbstractObjectiveTo investigate vitamin D status and its association with components of the metabolic syndrome (MetS) in adolescent girls attending high school in Boukan, Iran during winter 2012.DesignA cross-sectional study.SettingHigh schools of Boukan city, Iran.SubjectsA sample of 216 girls aged 14–17 years was selected by multistage random sampling from four districts of Boukan. Weight, height, waist circumference, blood pressure, daily energy intake, physical activity and serum 25-hydroxyvitamin D (25(OH)D), fasting blood glucose, TAG and HDL-cholesterol levels of all participants were evaluated. Serum 25(OH)D level <20 ng/ml was defined as vitamin D deficiency.ResultsMean serum 25(OH)D was 7·26 (sd 2·81) ng/ml and 96 % of the participants had vitamin D deficiency. According to age-modified definitions of the National Cholesterol Education Program Adult Treatment Panel III, MetS was diagnosed in 10·6 % of the participants. In multivariable regression analysis after adjustment for BMI, energy intake and physical activity level, serum 25(OH)D was inversely associated with fasting blood glucose (β = −0·143, P = 0·04). No significant relationship was found between serum 25(OH)D and other components of MetS.ConclusionsThe high prevalence of vitamin D deficiency warrants national polices and interventions towards improving this major health problem among adolescent girls. Low 25(OH)D level was significantly associated with increased fasting blood glucose. Prospective studies are needed to determine the effects of vitamin D deficiency on the development of MetS and related metabolic diseases in adolescent girls.

Zusammenfassung Hintergrund Nährstoffbezogene Empfehlungen müssen in lebensmittelbasierte Richtlinien übersetzt werden, damit sie für die Bevölkerung anwendbar werden. Noch praxisnäher sind mahlzeitenbezogene Richtlinien, gerade für die Kinderernährung. Diese Public-Health-Empfehlung wird in Deutschland mit dem Präventionskonzept der Optimierten Mischkost (OMK) für Kinder und Jugendliche umgesetzt. Verschiedene Überarbeitungen der D-A-CH-Referenzwerte für die Nährstoffzufuhr erforderten eine Neuberechnung der OMK. Methodik Ausgangsbasis waren Speisepläne für 4 Wochen (28 Tage) für 4 – 6-jährige Kinder als Referenzaltersgruppe. Mit einer vorsichtigen Optimierung von Lebensmittelauswahl und -mengen unter Berücksichtigung bevorzugt verzehrter Lebensmittel bei Kindern und Jugendlichen und üblicher Mahlzeitengewohnheiten (3 Haupt- und 2 Zwischenmahlzeiten am Tag) sollten die empfohlenen maximalen Nährstoffdichten (g[mg]/1000 kcal) im Altersbereich von 1 – 18 Jahren erreicht werden. Unter Annahme eines Energiebedarfs bei geringer körperlicher Aktivität (Physical Activity Level PAL 1.4) wurden altersgemäße Verzehrmengen für 11 Lebensmittelgruppen pro Tag und pro Mahlzeit ermittelt. Ergebnisse Allein mit herkömmlichen Lebensmitteln ohne Nährstoffanreicherung konnte bei den betrachteten Nährstoffen eine empfehlungsgerechte Zufuhr erreicht werden, mit Ausnahme der generell kritischen Nährstoffe Vitamin D und Jod. Dabei sind die Anteile der Lebensmittel am Gesamtverzehr pro Tag und pro Mahlzeit in allen Altersgruppen gleich, lediglich die Mengen ändern sich mit dem Energiebedarf. Die mahlzeitenspezifischen Nährstoffprofile ergänzen sich in einem Baukastensystem zu einer ausgewogenen Tagesernährung. Schlussfolgerung Mit dem durchkalkulierten Konzept der Optimierten Mischkost steht ein Referenzinstrumentarium für eine präventiv ausgerichtete Ernährung von Kindern und Jugendlichen zur Verfügung. Es kann für gesunde und kranke Kinder und Jugendliche in der Familienernährung und der Gemeinschaftsverpflegung angewendet werden.

Abstract Background Previous research has shown that bone mineral density (BMD), a measure of bone strength, may be lower among people with haemophilia. However, the majority of this research has been done in adults and in countries where the treatment for haemophilia differs from the standard of care in Canada, and there is a lack of paediatric data. Aims The primary objective of this study was to determine whether Canadian children and youth with severe haemophilia A and B have BMD similar to healthy controls matched for height, age and weight (HAW-score). Secondary objectives included the exploration of any association between BMD and the following variables: factor replacement regimen, Hemophilia Joint Health Score (HJHS), bleeding history, physical activity level, and dietary intake of calcium, vitamin D, vitamin K and protein. Methods A cross-sectional observational study was designed to determine the BMD of children with severe haemophilia A and B in Canada. Ethical approvals were obtained from participating institutions. Thirty-eight participants aged 3–18 with severe haemophilia A and B were recruited from two treatment centres in Canada. Subjects underwent dual-energy X-ray absorptiometry (DXA) scan, and data was collected from regular clinic visit to identify factor replacement regimen, HJHS, and number of joint bleeds over the lifespan. Physical activity level and dietary intake of calcium, vitamin D, vitamin K and protein were identified using self-report questionnaires. Results Participants showed a mean spine BMD Z-score and HAW-score higher than controls, with no participants showing a spine Z-score or HAW-score of <0. Hip BMD score was within normal range, and 2 participants had a Z-score and HAW-score of <−2. Total body BMD score was lower than controls, with 6 participants having a Z-score of <−2.0, and 3 participants having a HAW-score of <−2.0. Factor replacement regimen, HJHS, calcium intake, and physical activity level had no relationship to BMD Z-score or HAW-score. Low intake of vitamin D was associated with a low hip and spine BMD Z-score and HAW-score. Participants with a HJHS joint score greater than 0 had a higher total body HAW-score than those who had a joint score of 0. Conclusion Canadian children with severe haemophilia A and B demonstrate differences in spine and total body BMD from height-, age-, and weight-matched controls, where spine BMD is higher than controls and total body BMD is lower than controls. Studies with a larger sample size are needed to clarify the status of BMD in children with haemophilia treated with primary prophylaxis.

Background/Aims: Asian Indians have a high prevalence of vitamin D deficiency and metabolic syndrome. Vitamin D deficiency is associated with an increased risk of cardiovascular disease and diabetes. Methods: We performed a cross-sectional study of 150 Asian Indians (50% male) from the San Francisco Bay Area. We assessed the association between 25-OH vitamin D (25-OHD) levels and vitamin D deficiency with body composition (anthropometric and radiographic measures) and metabolic outcomes. Results: In both men and women, the presence of vitamin D deficiency was associated with higher systolic (p = 0.004) and diastolic (p = 0.01) blood pressure, and fasting glucose (p = 0.01). Only in women, vitamin D deficiency status was associated with higher body mass index (BMI), waist-to-hip ratio, visceral fat area, and hepatic fat content after adjusting for age, income, and physical activity level. In women, 25-OHD was also associated with fasting glucose after adjusting for age, income, and physical activity and further adjusting for BMI and waist circumference (β –2.1, 95% CI –0.86 to –0.01, p = 0.04). This association between vitamin D deficiency and metabolic parameters was not significant in men. Conclusions: A lower level of 25-OHD and vitamin D deficiency were associated with higher levels of metabolic factors among Asian Indians. Our findings suggest that 25-OHD metabolism may differ by the distribution of adipose tissue and involve previously unexplored pathways accounting for the variability in the role of vitamin D in cardiovascular disease.

Adherence to lifestyle changes - beginning to exercise, for example - is assumed to be mediated by self-referent thoughts. This paper describes a pilot study and three studies conducted to develop and validate a questionnaire for adults to determine their self-perceptions related to health-oriented exercise. The pilot study identified items pertinent to the domains considered important in this context, and began the process of selecting items. Study 2 examined the factor structure, reduced the number of items, determined the internal consistency of the factors, and explored the discriminative validity of the questionnaire as to physical activity level and gender. Four factors with a total of 24 items were accepted, measuring mastery of exercise, body perception, social comfort/discomfort in the exercise setting, and perception of fitness. All subscales had acceptable internal consistencies. Preliminary validity was demonstrated by confirming hypothesized differences in scores as to gender, age, and physical activity level. The third study examined and demonstrated convergent validity with similar existing subscales. The fourth study examined an English-language version of the questionnaire, confirming the existence of the factors and providing preliminary psychometric evidence of the viability of the questionnaire.
