Introduction: Dietary changes play a role in metabolic response of patients with metabolic-associated fatty liver disease, and there is little evidence on the use of partial meal replacement (pMR) diets in this pathology.

Aim: We decided to evaluate the modifications in transaminases levels after a pMR hypocaloric diet in subjects with obesity and elevated fatty liver index (FLI).

Material And Methods: A sample of 606 patients with obesity and FLI ≥ 60 were enrolled and treated during 3 months with a pMR diet.

People who are blind do not have access to graphical data and imagery produced by science. This exclusion complicates learning and data sharing between sighted and blind persons. Because blind people use tactile senses to visualize data (and sighted people use eyesight), a single data format that can be easily visualized by both is needed.

Hereditary ataxias are a group of devastating neurological disorders that affect coordination of gait and are often associated with poor coordination of hands, speech, and eye movements. Ataxia with ocular apraxia type 1 (AOA1) (OMIM: 606,350.0006) is characterized by slowly progressive symptoms of childhood-onset and pathogenic mutations in APTX; the only known cause underpinning AOA1.

Article Synopsis
  • The CDKAL1 gene influences insulin secretion and glucose regulation, specifically through the rs7756992 genetic variant.
  • A study involving 44 obese individuals following a partial meal replacement diet revealed notable effects on fasting glucose and insulin resistance based on genetic variations.
  • Non-G allele carriers experienced significant improvements in fasting glucose, insulin levels, and HOMA-IR compared to G allele carriers after the diet, indicating a link between the genetic variant and glycemic response.

Aim: the objective of our real-life study was to evaluate adherence and taste preferences of a hypercaloric and hyperprotein oral nutritional supplement (ONS) in malnourished hospitalized patients. Methods: a total of 34 in patients with recent weight loss were included in this study. One flavor (coffe, vanilla or strawberry) was administered each day in a random way to each patient during three consecutive days.

Background: cancer patients are a group at high nutritional risk. Oral nutritional supplementation (ONS) can improve nutritional status. Objective: the objective of our study was to evaluate the effectiveness on nutritional parameters and quality of life of a ω3-enriched ONS in oncology outpatients in a real-world study.

The role of gene variants on metabolic improvements after weight change secondary to different hypocaloric diets remained unclear. We evaluate the effect of rs3774261 of polymorphism on biochemical improvements and weight change after high polyunsaturated fat hypocaloric diet with a Mediterranean dietary pattern for 12 weeks. A population of 361 obese subjects was enrolled in an intervention trial with a calorie restriction of 500 calories over the usual intake and 45.

Handheld models help students visualize three-dimensional (3D) objects, especially students with blindness who use large 3D models to visualize imagery by hand. The mouth has finer tactile sensors than hand, which could improve visualization using microscopic models that are portable, inexpensive, and disposable. The mouth remains unused in tactile learning.

Background: The CDKAL1 (CDK5 Regulatory Subunit Associated Protein 1 Like 1) gene encodes cyclin-dependent kinase 5 (CDK5) regulatory subunit-associated proten1 like 1. This protein has been shown to contribute to the glucose-dependent regulation of insulin secretion in pancreatic islets.

Aims: The aim of our study was to analyze the effects of the rs7756992 genetic variant of CDKAL1 gene on fasting glucose and insulin resistance after weight loss secondary to partial meal replacement hypocaloric diet (pMRHD).

Background: the SNP 3´UTR C/T (rs10401670) of the RETN gene is a polymorphism that has been associated with the presence of type-2 diabetes mellitus in a single work in the literature. Objective: the objective of our study was to evaluate the influence of this resistin gene SNP (rs10401670) on the serum levels of resistin, as well as on the presence of type-2 diabetes mellitus in obese subjects and on insulin resistance. Material and methods: a Caucasian population of 653 obese subjects was analyzed.

Our primary objective was to assess the independent association between liver fibrosis (LF) and abdominal fat accumulation (AFA) and fatty liver disease (FLD). We also aimed to determine the diagnostic accuracy of AFA and FLD for the prediction of cirrhosis measured using unenhanced low-dose computed tomography (CT). This is a cross-sectional study in stable human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients with active HCV replication.

Objective: the purpose of this investigation was to investigate the associations between nutritional status by Mini Nutritional Assessment (MNA) test and dysphagia by EAT-10 in elderly individuals requiring nutritional oral care in an acute hospital.

Patients: this was a cross-sectional survey covering a sample of 560 elderly individuals. As anthropometric parameters, weight and body mass index (BMI) have been included.

Background: There is little evidence of the association between CETP SNPs and obesity and/or related metabolic parameters.

Objective: To analyze the association of the polymorphism rs1800777 of the CETP gene with anthropometric parameters, lipid profile, metabolic syndrome and its components, and adipokine levels in obese subjects without type 2 diabetes mellitus or hypertension.

Design: A population of 1005 obese subjects was analyzed.

Background/aims: The aim of our study was to evaluate the influence of lifestyle factors and molecular biomarkers on the maintenance of the weight lost after a hypocaloric Mediterranean diet.

Design: After 3 months on a diet, patients (n = 335) remained with no controlled diet during 3 years and they were revaluated.

Results: Using linear regression, in the group of responders, we detected that a positive weight loss at 3 months, serum levels of leptin at 3 months, and each 30 min per week of physical activity were associated with weight loss maintenance.

Objectives: Liver fibrosis (LF) is crucial for the individualized management of patients with hepatitis C virus (HCV). We evaluated the concordance between two noninvasive methods for staging LF, transient elastography (TE) and acoustic radiation force impulse (ARFI), in patients coinfected with human immunodeficiency virus and HCV. We propose an algorithm for optimal use of both techniques in routine clinical practice.

The factors associated with overall mortality and liver decompensation in HIV and hepatitis C virus (HCV)-coinfected patients who are evaluated to receive HCV antiviral therapy with a known liver histological fibrosis stage were evaluated in a prospective cohort study. A total of 387 consecutive HIV/HCV-coinfected patients attending an outpatient clinical unit between January 1997 and December 2007 who fulfilled criteria to be treated with interferon and to whom liver biopsy was performed were included and followed every 6 months from time of liver biopsy to death or to December 2008. The follow-up period was 6.
