Filter by:It is widely known that the quality of the diet is able to modify the expression of many bacterial genes populating the intestine of the host, as well as the type of bacteria themselves. This is also expressed with a more or less evident and troublesome after meals symptomatology that many patients complain to the health care staff. A good composition of the microbiota is crucial for the health of the individual, both at the intestinal level as well as at the systemic level because, depending on the type of food substrate available at the intestinal level, metabolites will be produced capable of positively or negatively affect the health of the individual. In fact, scientific evidence shows the existence of the causal link between the health of the microbiota and the genesis of inflammatory diseases not only intestinal, but also systemic, and even of cancer, obesity, metabolic syndrome and atherosclerosis. The recent diffusion of gene sequencing techniques has brought significant developments in the study of the human and bacterial genome, which allow to produce enormous quantities of sequences at a lower cost and at a higher speed than previous techniques. Therefore the clinical Nutrition Clinic of the IRCCS De Bellis in Castellana Grotte (BA) proposes to check if changes in the intestinal microbiota correlate, not only with anthropometric and clinical-laboratory parameters, but also with the typical symptoms of irritable bowel syndrome (IBS), a functional pathology very widespread with the advent of the modern era, in which, a diet rich in sugars and proteins of animal origin and poor in plant foods, is unfortunately common also in the areas of the Mediterranean basin.
The aim of the study was to evaluate the effects of hypotensive treatment combined with a higher zinc supply in the diet and supplements on the mineral status and selected biochemical parameters of newly diagnosed hypertensive patients on monotherapy.
Introduction Sarcopenia is defined as progressive generalized loss of skeletal muscle mass, strength and function. Sarcopenia due to lack of physical activity is a known phenomenon and is usually observed as a normal part of aging or in certain diseases and pathogenic processes. Major associated factors causing development of sarcopenia may be summarized as interactions of environmental and hormonal factors, underlying diseases, activation of inflammatory pathways, mitochondrial dysfunction, reduced satellite cell numbers, and loss of neuromuscular junctions. Intensive care acquired weakness (ICU-AW) known formerly as critical illness polyneuropathy, is a diagnosis that becomes more common as survival rates from long ICU hospitalization are more prevalent. It is characterized by a primary axonal degeneration, without demyelination, that typically affects motor nerves more than sensory nerves. ICU-AW affects the limbs (particularly the lower extremities) in a symmetric pattern. Weakness is most notable in proximal neuromuscular areas (e.g., the shoulders and hip girdle). In addition, involvement of the respiratory muscles can occur and can impede weaning from mechanical ventilation. The pathophysiological mechanisms of ICU-acquired weakness are believed to be multifactorial. Some suspected factors include dysfunctional microcirculation and hyperglycemia. It has been shown that tight glucose control in ICU patients reduces the risk for ICU-AW (although it has been associated with other adverse events). Sodium channels channelopathy is also a researched cause for ICU-AW. Muscle loss in the ICU are usually related to bedridden condition and lack of mobility, increase in ubiquitination and inadequate protein administration associated with large negative nitrogen balance. In addition mechanical ventilation contributes greatly to this problem. This has been particularly relevant in post trauma/surgical long stayer patients. In the past years great progress was made in the investigation of protein balance, breakdown and synthesis using stable isotope tracers in various medical conditions. In a research performed in PICU (1-5) and ICU (6, 7) regarding the measurement of plasma amino acid during critical illness, stable phenylalanine, tyrosine leucine, arginine and citrulline isotope were used intravenously without any safety issue problem. Another study was performed on adults suffering from COPD with matched healthy adults, using stable isotopes of phenylalanine, tyrosine leucine, isoleucine and valine (8). During the study the isotopes were given parenterally as well as enterally. The study showed significant change in splanchnic extraction of various amino acids and higher turnover of BCAA in COPD patients. Using the theory that supplemental milk can compensate for the elevated turnover of BCAA in COPD patients, using the isotope analysis demonstrated that this theory was proven wrong and the conclusion was that alterations are present in BCAA metabolism despite normal plasma levels in normal weight COPD. Further research is needed to find a way to compensate for it. These studies and other recent studies (9-19) show us the safety regarding the use of stable isotope tracers whether IV or PO, while giving us the opportunity to assess the metabolism of amino acid in all sorts of pathological states. Hypothesis & Aim of the study We think that based on current literature, there are important differences between critically ill patients and healthy population in the amino acid profile and distribution in the body as well as synthesis and breakdown. The aim of the study is to measure these differences in long ICU stayers (above 7 days) admitted in the ICU after surgical/trauma injury, and to try and help aiming future treatment and research in this field.
Cooking for Health Optimization with Patients (CHOP) is the first known multi-site prospective cohort study with a nested Bayesian adaptive randomized trial in the preventive cardiology field of culinary medicine. It is also the first known longitudinal study to assess the impact of hands-on cooking and nutrition education on patient outcomes, with those classes taught by medical students and other future and current medical professionals who have first been trained in those classes on how to integrate diet and lifestyle counseling of patients with their respective scopes of clinical practice. CHOP is the primary research study of the world's first known medical school based teaching kitchen, The Goldring Center for Culinary Medicine at Tulane University School of Medicine. Medical trainees and professionals are followed in this study long-term to understand how the classes impact their competencies in patient counseling, attitudes about the counseling, and their own diets. Patients who consent to being randomized to these classes compared to standard of care are studied within the nested Bayesian adaptive randomized trial to understand how the classes impact their health outcomes, clinical and food costs, and the costs of health systems caring for these patient populations. CHOP is designed as a pragmatic population health trial to hopefully improve healthcare effectiveness, equity, and cost by establishing an evidence-based, scalable, sustainable model of healthcare intervention targeting the social determinants of health, while complementing the pharmacological and/or surgical management of patients.
Patients admitted to the ICU with diagnosis of sepsis and requiring mechanical ventilation for at least 24-hours and receiving enteral or parenteral nutrition will be prospectively randomized to one of two arms. Patients allocated to the estimated energy expenditure group will receive nutrition with caloric intake calculated based on the Penn State equation. Patients randomized to the measured group will receive nutrition with caloric intake calculated based on IC measurement present in the GE ventilator. Patients in the estimated group will have IC performed, but these data will not be used for prescription of nutrition. An equal number of beds within the ICU will be allocated to the measured group and the estimated group. The primary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improvement in muscular structure, and consequent reduction of mechanical ventilation duration in patients with sepsis in comparison to utilizing the Penn State estimation equation for caloric goal calculation. The secondary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improved adequacy of nutritional delivery in comparison to the adequacy of nutritional delivered when utilizing the Penn State estimation equation. Adult patients (> 18 years of age) admitted to the hospital with diagnosis of sepsis, and who require mechanical ventilation during hospitalization will be considered. Patients newly ventilated for at least one day but less than three days will be included in the study. Informed consent will be obtained from the legal authorized representative (LAR).
The aim of the study is to determine the factors affecting the bioavailability of iron and folic acid during the simultaneous use of iron supplements and folic acid supplements in non-pregnant women of childbearing age.
This cluster randomized controlled trial will test the effect of the promotion of vitamin A-rich orange flesh sweet potato (OFSP) production and nutrition education on vitamin A and energy intake, including any added value of the Healthy Baby Toolkit.
An observational study was conducted in a health examination center to distinguish risk factors for health in a randomly recruited volunteers of Chinese population.
Malnutrition or its risk is common among older people, especially among those receiving home care services. It impairs the quality of life of the older people and results in significant costs to society. To maintain adequate nutrition, increased meal frequency is important. In addition to main meals, regular consumption of tasty, convenient, nutrient- and energy-dense snacks is recommended. The purpose of this study is to investigate the effects of dairy- and berry-based snack consumption on nutritional and functional status and quality of life among vulnerable older people at home care.
The purpose of this study is to learn if participants in the ADORE study (NCT02626299), who took a DHA supplement during pregnancy, see favorable body fat in their infants from birth to 24 months, and if excessive or appropriate weight gain during pregnancy impacts this result.
