Nutrition Assessment and Dietary Interventions in Heart Failure: JACC Review Topic of the Week.

Despite the high prevalence of nutrition disorders in patients with heart failure (HF), major HF guidelines lack specific nutrition recommendations. Because of the lack of standardized definitions and assessment tools to quantify nutritional status, nutrition disorders are often missed in patients with HF. Additionally, a wide range of dietary interventions and overall dietary patterns have been studied in this population. The resulting evidence of benefit is, however, conflicting, making it challenging to determine which strategies are the most beneficial. In this document, we review the available nutritional status assessment tools for patients with HF. In addition, we appraise the current evidence for dietary interventions in HF, including sodium restriction, obesity, malnutrition, dietary patterns, and specific macronutrient and micronutrient supplementation. Furthermore, we discuss the feasibility and challenges associated with the implementation of multimodal nutrition interventions and delineate potential solutions to facilitate addressing nutrition in patients with HF.

Normalising birth for women with a disability: the challenges facing practitioners.

UNLABELLED: Previous research on pregnant women with a disability and their experience of maternity care demonstrated that these mothers perceived themselves to be the 'perennial outsiders' with midwives automatically categorising them as 'high risk' because of their disability. They also felt that their ability to make choices, stay in control and have continuity of care was not considered to be part of the mainstream maternity care for them because they did not fit the 'normal' category. OBJECTIVE: this research was undertaken to explore the perceptions of two multiprofessional teams in Irish hospitals as to how maternity services to these mothers can be improved. PARTICIPANTS: nineteen health-care professionals from midwifery, social work and public health nursing were recruited. SETTING: two from two major maternity hospitals, one in the North and one in the South of Ireland. were featured. DESIGN: the method chosen was a qualitative approach, using focus group interviews in which case studies depicting a range and breadth of women's birthing experiences were presented and discussed. Newell and Burnard's (2006) six stage approach to thematic content analysis was used. FINDINGS: the professionals found the disabled women's stories believable, upsetting and challenging. KEY CONCLUSIONS: Staff acknowledged their 'lack of competence, knowledge and skill' regarding disability and felt that, on reflection, their failure to consult and collaborate with disabled women contributed to their failing to provide individualised woman centred care to women with a disability. IMPLICATIONS OF PRACTICe: A series of recommendations for improved practice was agreed.

Nutrition therapy of the severely obese, critically ill patient: summation of conclusions and recommendations.

This report compiles the conclusions and recommendations for nutrition therapy of the obese, critically ill patient derived by the group of experts participating in this workshop on obesity in critical care nutrition. The recommendations are based on consensus opinions of the group after review of the current literature. Obesity clearly adds to the complexity of nutrition therapy in the intensive care unit (ICU). Obesity alters the incidence and severity of comorbidities, tolerance of the prescribed regimen, and ultimately patient outcome through the course of hospitalization. Although the basic principles of critical care nutrition apply to the obese ICU patient, a high-protein, hypocaloric regimen should be provided to reduce the fat mass, improve insulin sensitivity, and preserve lean body mass. The ideal enteral formula should have a low nonprotein calorie to nitrogen ratio and have a variety of pharmaconutrient agents added to modulate immune responses and reduce inflammation.

Comparison of body composition methods during weight loss in obese women using herbal formula.

Bioelectrical impedance analysis (BIA), a device that analyzes the current conduction differences between the fat and water components is widely used for reasons that include convenience of use, non-invasiveness, safety, and low cost. Dual energy X-ray absorptiometry (DXA) allows for the assessment of total body and regional lean and fat tissues and bone mineral content (BMC). The objective of this study was to compare body composition assessments by BIA and DXA before and after a 6-week herbal diet intervention program in 50 pre-menopausal women [mean +/- SD: age 30.58 +/- 6.15, body mass index (BMI) 31.72 +/- 3.78]. Waist-to-hip ratio (WHR) was measured by BIA and anthropometry. Lean body mass (LBM), body fat (BF), BMC and percent body fat (%BF) were measured by BIA and DXA. Highly significant correlations were observed between BIA and DXA measurements for LBM, BF, BMC and %BF (r = 0.73, 0.93, 0.53, 0.79, respectively) before the intervention. Differences between BIA and DXA measurements were observed in LBM, BF, %BF and BMC before intervention (p < 0.01) where WHR by BIA was significantly higher compared to anthropometry before (p < 0.01) and after the intervention (p < 0.01). BIA underestimated LBM by 1.85 kg and overestimated BF by 2.54 kg compared to DXA before the intervention. Although BIA and DXA showed highly significant correlations for LBM, BF, BMC and %BF before the intervention, they did not produce statistically comparable results in pre-menopausal Korean women and therefore should not be used interchangeably when measuring body composition.
