Filter by:The aim of the study is to determine whether the optimisation of the preoperative nutritional status affects the course of the perioperative period in patients with frailty. Subjects: Patients 65 and over years of age with frailty or risk of it, with suboptimal nutritional status who are prescribed to elective cardiac surgery . Research methods: Edmonton Crispness Scale, a Mini Nutritional Assessment (MNA-SF) test will be used to select subjects. Body composition will be examined by bioelectrical impedance analysis (BIA) to determine the degree of phase angle. Changes in laboratory blood tests will be recorded and evaluated The subjects randomly will be divided into control and study groups. The diet of the patients in the study group will be optimised by protein supplements before elective heart surgery. The benefits of optimising nutritional status will be evaluated comparing laboratory blood tests, changes in organ function, adverse outcomes, the need for vasoactive drugs, artificial lung ventilation time and length of hospitalisation between the groups.
Nutritional status during pregnancy plays an important role in maternal health and birth outcomes. While few factors impacting nutritional status during pregnancy have been identified, studies of undernutrition in children have revealed a key role for the gut microbiome. Remarkably, studies examining the dynamics of the maternal gut microbiome before and during pregnancy and its impact on birth outcomes are limited. This study is being conducted to investigate how a mother's nutritional status and her gut microbiome during pregnancy contribute to the birth outcomes and health of her baby. The gut microbiome is the totality of microorganisms (e.g. bacteria, viruses, fungi) living in the gastrointestinal tract. This study will focus on married pregnant women 24 years and younger living in Matiari District in Pakistan. The focus is on younger women due to their vulnerability to undernutrition. Pregnant participants, and upon delivery, their newborns will be followed throughout pregnancy and for a year afterwards. Throughout this period, the investigators will collect stool samples, rectal swabs, blood samples, health assessments, nutritional and dietary assessments and birth/ labour details. The goal is to define the relationship between a mother's nutritional status and her microbiome dynamics during pregnancy and how they contribute to the birth outcomes and growth of her newborn. Investigators hypothesizes that alterations of the microbiota in the maternal gut (dysbiosis) is exacerbated by nutritional status or pathogen exposure during pregnancy. This impacts weight gain because of impaired nutrient absorption, and can lead to corresponding negative birth outcomes.
The CAREPATH will conduct Technical Validation and Usability (TVU) study by involving ≥ 45 target end users (16 patients with MCI or mild dementia with their informal caregivers and 16 healthcare professionals from various disciplines) and Clinical Investigation (CI) study involving ≥ 200 patients (≥ 100 users to pilot the CAREPATH platform and ≥ 100 patients as reference cases). Both of these pilot studies will be coordinated in four European countries (Spain, Romania, Germany and UK) with diverse health and social care systems, ICT landscape/digital maturity of healthcare provision and dementia national programs, which will allow for strengthening the evidence base on health outcomes and efficiency gains. The CAREPATH outcomes can be summarized as: 1. An Integrated Care Platform that jointly addresses multimorbidity, dementia and diminished intrinsic capacity and optimally manages healthcare interventions for its users (patients, informal caregiver, healthcare providers, etc). 2. Technical Validation and Usability (TVU) study involving over 45 users and Clinical Investigation (CI) involving over 200 patients that will be conducted in four European countries (Spain, Romania, Germany and UK) during two years and mobilizing the other necessary actors, such as caregivers and healthcare professionals, for the validation of healthcare interventions. 3. Dementia / Multimorbidity Guidelines that will be conceived for best healthcare delivery. 4. Health Economics Impact Assessment for healthcare cost effectiveness and care provision equalities. The incremental cost-effectiveness and the incremental cost-utility ratio would allow revealing the incremental cost (or the potential savings) per unit of benefit of switching from usual care to CAREPATH-an integrated patient-centred approach- in multimorbid elderly patients with dementia, and therefore, to determinate whether the CAREPATH approach would be considered as a cost-effective alternative.
Malnutrition and sarcopenia (muscle wasting) are common in health care settings and represent a health and economic burden due to associated increased mortality and prolonged hospital stays. Nutritional therapy co-management is recommended for both diagnoses. This study investigates the efficacy of individualized nutrition therapy (iNT) in pulmonary rehabilitation. Patients at significant risk for malnutrition already receive iNT within clinical routine during rehabilitation. The investigators will investigate if patients with only mild to moderate risk of malnutrition and possible sarcopenia also benefit from iNT.
Background: Children with acute malnutrition have immature gut microbial communities compared to age-matched children with healthy growth that can not be repaired by existing therapeutic foods (Subramanian et al., Nature. 2014). Hence, investigators' recent work in Bangladesh has focused on developing Microbiota-Directed Complementary Foods (MDCF) containing locally-available food ingredients, that repair the gut microbiota of children with acute malnutrition to a configuration that resembles that of healthy children living in the same urban community (Raman et al., Science 2019; Gherig et al., Science 2019). The investigators recently completed a randomized, controlled proof-of-concept (POC) study of current lead microbiota-directed complementary food, MDCF-2 compared to a standard ready-to-use supplementary food (RUSF), in Bangladeshi children with moderate acute malnutrition (MAM)(Chen et al., N Engl J Med 2021). Children who received MDCF-2 for 3 months exhibited significantly greater repair of their gut microbial communities and faster rates of ponderal growth compared to those treated with RUSF (a formulation that was not designed based on knowledge of its effects on the gut microbiota). The superior effect of MDCF-2 on gut microbiota repair and weight gain was even more notable as the RUSF was significantly more energy dense than MDCF-2. In the aforementioned POC study, MDCF-2 was prepared fresh daily in icddr,b field kitchens prior to distribution and supervised administration to study participants. The lack of a shelf-stable, bio-equivalent formulation of MDCF-2 limits the ability to perform larger studies in Bangladesh as well as in other geographic settings. This pre-POC study in Bangladeshi children with MAM will assess the bioequivalence of MDCF prototypes that the investigators have developed with the potential for improved storage stability compared to current MDCF-2, using the degree of microbiota repair after 4-weeks of treatment as the primary outcome. Objective: To develop a scalable, shelf-stable formulation that is bioequivalent to MDCF-2 with respect to microbiota repair in 8-12 month-old Bangladeshi children with MAM after 4-weeks of treatment. Methods: A 5-arm, randomized single-blind pre-POC study will be conducted in 8-12-month-old Bangladeshi children with MAM to compare the efficacy of alternative MDCF formulations in repairing their gut microbiomes compared to the repair produced by the current kitchen prepared MDCF-2 formulation. Arm 1 - Reference control: kitchen-prepared MDCF-2 Arm 2 - Ready-to-use supplementary food Arm 3 - Individually packaged, pre-measured sachets of MDCF-2 ingredients, combined and reconstituted in the home setting prior to consumption. Arm 4 - MDCF-2 shelf-stable foil pouch formulation with green banana powder. Arm 5 - MDCF shelf-stable foil pouch formulation with sweet potato instead of green banana.
This is a pilot study to test how a growing-up formula (GUF) compares to a common nutritional supplement (NS), which is regularly used to help toddlers (ages 12-36 months) gain weight. This study will look at whether GUF helps to increase solid food intake for children who are thought to be "picky eaters" and see the effects on growth compared with the NS. To date, it is not clear if GUFs help to increase intake of solid foods. Participants will be placed into one of the two study arms: Enfagrow (GUF) or Pediasure (standard NS).
The present study aims to investigate the prognostic value of preoperative fat-free mass index for postoperative outcomes in patients undergoing esophagogastric cancer surgery, and to explore the role of the FFMI in the Global Leadership Initiative on Malnutrition (GLIM) criteria.
Background: Burden: Globally, an estimated 14.3 million under-5 children are severely malnourished. Two-thirds of them live in Asian countries, including Bangladesh. Acute malnutrition is an underlying cause of nearly half of global deaths in under-5 children despite standardized rehabilitation protocols. It is also associated with high relapse rates following discharge. Knowledge Gap: Malnourished children suffer from deficiencies of several essential nutrients. Studies showed that malnourished children had lower serum carnitine levels and demonstrated its role in the rate of weight gain in children with severe acute malnutrition (SAM). The consequences of nutritional impairment can be perilous if carnitine deficiency is coupled with Environmental Enteric Dysfunction (EED). Recent evidence confirms that EED is characterized by secondary carnitine deficiency in children. Carnitine deficiency leading to EED may cause childhood growth faltering and impaired cognitive development. However, evidence on carnitine status and its consequences in relation to EED in diarrheal children with SAM is very limited in Bangladesh. Relevance: Such lack of information regarding the role of L-carnitine in improving the rate of weight gain in malnourished children susceptible to EED is an obstacle in limiting the relapse and adverse consequences of SAM in diarrheal children living in resource-limited countries. Hypothesis: L- carnitine supplementation for 15 days in children with SAM will improve the rate of weight gain and biomarkers of EED Objective: 1. To investigate the role of L-carnitine supplementation on the rate of weight gain among the children with SAM 2. To investigate the role of L-carnitine supplementation on the duration of the hospital stays 3. To examine the role of L-carnitine supplementation on EED biomarkers, for instance, myeloperoxidase (MPO), neopterin (NEO), alpha-1 anti-trypsin (A1AT), kynurenine: tryptophan (KT) ratio, and citrulline in children with SAM Methods: This study will be a double-blinded, placebo-controlled randomized clinical trial
The purpose of this study is to evaluate the feasibility and effectiveness of weekly iron and folic acid (IFA) supplementation and one-time deworming treatment at the community level in improving hemoglobin levels among adolescent girls in Liberia, West Africa, and to assess the feasibility and effectiveness of a targeted nutrition education program in improving nutrition knowledge, attitudes, and practices in the same population.
EE is increasingly recognized as a key factor underlying malnutrition, weakened immune response and impaired cognitive development in children in developing countries. Absence of a distinct biomarker of EE in the blood, urine or stool makes it difficult to study the impact of interventions against it. Biomarkers for EE have been challenging to find, partly because of our inadequate understanding of its pathophysiology. Investigators aim to identify novel biomarkers for EE, based on our hypothesis that EE is a result of two processes: 1) repeated exposure to enteric pathogens and environmental toxins leading to gut inflammation and 2) weaning on diets high in carbohydrates but low in proteins and fat, leading to atrophy of the intestinal mucosa. This leads to gut dysfunction, including leaky gut, small bowel stasis, bacterial overgrowth, decreased immune response to infections, and frequent diarrhea. The candidate biomarkers investigators have selected for our study (CRP, GLP- 2, Claudin 3, Reg-1, plasma amino acids profile, serum cytokine profile, Neopterin and Myeloperoxidase) are markers of inflammation, hormonal dysfunction and tight junction malfunction of the small intestines. The 'gold standard test' for EE will be direct histopathologic analysis of the duodenal mucosa, which will be available in a subset of study children undergoing upper GI endoscopy. For other study subjects, clinical surrogates for EE will be used to calculate the sensitivity and specificity of biomarkers being tested. These clinical surrogates of EE include HAZ and WAZ score < 2 SD at 12 months and 15 months of age, and the worsening in HAZ and WAZ scores between 6, 9, 12 and 15 months of age. Investigators plan to study and compare duodenal biopsies from children with and without EE using cutting edge technologies including electron microscopy, immunofluorescence, and mRNA sequencing. This will allow direct correlation of the biomarkers in the blood, urine and stools with the histopathologic features of the gut mucosa. The mRNA sequencing of the gut tissue will allow us to identify new evidence-based biomarkers for EE, which could be further tested in the future. This is a strong, multidisciplinary collaboration between investigators in Pakistan and the United States with expertise in complementary areas including chemokines, inflammation, gut architecture, infectious diseases, field studies, and technology development.
