High Dietary Sodium Intake is Associated with Shorter Event-Free Survival in Patients with Heart Failure and Comorbid Diabetes.

The aim was to determine whether 24-hour urine sodium excretion predicted event-free survival of patients with heart failure (HF) and diabetes mellitus (DM). Twenty-four hour urine sodium, as an indicator of dietary sodium, was collected from 107 patients with HF and comorbid DM. Patients were followed for a median period of 337 days to determine time to the first event of either all-cause hospitalization or cardiac-related mortality. There were 44 patients (41%) who had an event of death or hospitalization. Cox regression showed that higher urine sodium (>3.8 gm/day) was associated with 2.8 times greater risk for an event than lower urine sodium after controlling for age, gender, New York Heart Association class (I/II vs. III/IV), left ventricular ejection fraction, and body mass index. These data suggest that dietary sodium restriction may be beneficial for patients with HF and DM

The health outcomes of inflammation and obesity in patients with heart failure.

BackgroundAlthough obesity is a risk factor for cardiovascular disease, higher body mass index is related to longer event-free survival in patients with heart failure (HF). While previous research demonstrated that higher levels of inflammatory mediators were associated with shorter event-free survival, the effect of inflammation on the association between obesity and outcomes of HF have not been considered.HypothesisBased on the obesity paradox, we hypothesized that patients with higher baseline body mass index (BMI) would experience better event-free survival than those with lower BMI regardless of inflammatory status.MethodA sample of 415 patients with HF (age 61 ± 11.5 years; 31% female) provided blood to measure soluble tumor necrosis factor receptor1 (sTNFR1), a biomarker of inflammation. Patients were divided into 4 groups based on BMI and a median split of sTNFR1 levels: (1) high BMI ≥ 30 and sTNFR1 > 1804 pg/ml, (2) high BMI ≥ 30 and low sTNFR1 ≤ 1804 pg/ml, and (3) low BMI  1804 pg/ml vs. (4) low BMI ResultsThere were 177 patients (43%) who experienced either an all-cause hospitalization or death. In a Cox regression, high BMI and high sTNFR1 category predicted time to event (hazard ratio = 1.7, 95% confidence interval = 1.01-2.9) with age, gender, race, left ventricular ejection fraction, New York Heart Association functional class (I/II versus III/IV), log-transformed N-terminal Pro-B-type natriuretic peptide levels, prescribed statin (yes/no), and comorbidity as covariates.ConclusionBeing in a higher inflammation group was associated with shorter event-free survival regardless of BMI. This study provides evidence that inflammation is an important consideration in the association between obesity and better outcomes in patients with HF

The Preventable Effect of Taekwondo Sport among Cadets and Junior’ Bone Mineral Density: DEXA Assessment

Athletes competing in Taekwondo (TKD), the weight-category sport, tend to rapidly lose weight to achieve the desired body weight for better competitive results. Little is known about the effect of rapid weight reduction on bone mass density (BMD), especially during childhood and adolescence. The current study aimed to investigate the impact of rapid weight loss on BMD among cadets and juniors TKD athletes. A descriptive case series study design was conducted and collected from 28 males and females aged 12–17 years old, with mean age 14.4 ± 1.7. Dual-energy X-ray absorptiometry (DEXA) was used for both BMD and body composition assessment, and laboratory tests were also performed for the total calcium (Ca), TSH, free T4 (FT4), and 25-OH-vitamin D. Results showed normal levels of Ca (82.1%), TSH (96.4%), and FT4 (96.4%), whilst 85.7% had vitamin D deficiency. DEXA results showed that within male athletes, juniors had a wider range of BMD than cadets, while within females, results did not vary, with no statistical difference between both males and females. Our results suggested that children and adolescents’ BMD was positively related to TKD sport regardless of the abnormal weight loss strategies used, as evidenced by laboratory results. Children and adolescents should be conscious and practice TKD sport adopting healthy weight loss behaviors
