Platelet-to-albumin ratio: a potential biomarker for predicting all-cause and cardiovascular mortality in patients undergoing peritoneal dialysis

BackgroundAlthough peritoneal dialysis (PD) is an efficient therapy for renal replacement, the long-term survival rate of patients undergoing PD remains low. The platelet-to-albumin ratio (PAR), recently identified as a parameter of inflammatory and nutritional status, is associated with an adverse prognosis for various diseases. However, the association between the serum PAR and prognosis of patients undergoing PD is poorly understood. This study aimed to evaluate whether the PAR is a reliable predictor of cardiovascular disease (CVD) and all-cause mortality in patients undergoing PD.MethodsThis multicenter cohort study enrolled patients undergoing PD from January 1, 2009, to September 30, 2018. The patients were divided into four groups according to the quartiles of their baseline PAR. The primary endpoint was all-cause and CVD-related mortality. Cox proportional hazard models were used to determine the association between the PAR and all-cause or CVD-related mortality. The receiver operating characteristic (ROC) curve was utilized to compare the performance among PAR and other inflammatory indicators. C-statistic, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were applied to examine the incremental prognostic value of PAR compared with baseline model for predicting all-cause and CVD mortality.ResultsA total of 2825 patients were included. During the follow-up period of 47.5 ± 28.3 months, 747 (26.4%) mortality cases were observed, of which 415 (55.6%) were CVD-related. Compared with the Q1 (PAR < 4.43), placement in Q4 (PAR > 7.27) was associated with an increased risk of all-cause mortality and CVD mortality (p < 0.001). The adjusted restricted cubic spline analysis indicated that the relationship of the PAR with all-cause and cardiovascular mortality was linear (p for nonlinearity = 0.289 and 0.422, respectively). No positive correlations were shown in the interaction tests. PAR exhibited superior predictive value for mortality compared to other inflammatory indicators, with a respective AUC value of 0.611 (P < 0.001) for all-cause mortality and 0.609 (P < 0.001) for cardiovascular mortality. According to the C-statistic, continuous NRI and IDI, the addition of PAR to the baseline model yielded a moderate but significant improvement in outcome prediction.ConclusionsThe PAR is an independent prognostic factor associated with all-cause and cardiovascular mortality in patients undergoing PD.

Effects of Diet and Supplements on Parameters of Oxidative Stress, Inflammation, and Antioxidant Mechanisms in Patients with Chronic Renal Failure Undergoing Hemodialysis.

The prevalence of chronic kidney disease (CKD) worldwide increases as the population ages. The progression of the disease increases the risk of complications and death and leads to end-stage renal failure, requiring renal replacement therapy. Despite the positive effect of hemodialysis (HD), patients are at risk of developing malnutrition, inflammation, oxidative stress, or cardiovascular disease, which worsens quality of life and can lead to organ dysfunction. The occurrence of the mentioned disorders depends largely on the diet, so changes in diet composition are an important part of the treatment of kidney disease. This study aimed to evaluate the effects of a balanced diet on some parameters of oxidative stress, immune response, and nutritional status in patients. This study included 57 HD patients (19 women and 38 men). In all of them, nutritional status and diet were initially determined, and then, they were divided into six groups, which received different diets and supplements. Serum levels of albumin, total protein, MDA, and the cytokines Il-1, IL-6, IL-8, TNF-α, and IL-10 were determined, and the activity of the enzymes such as CAT, SOD, and GSH-Px were determined in erythrocytes by spectrophotometry. Based on the results of BMI, albumin, and total protein, it can be concluded that a well-balanced diet can reduce weight loss. This study shows that a well-balanced diet can reduce the secretion of pro-inflammatory cytokines, and ensure the normal activity of antioxidative enzymes in the blood of HD patients.

Hygienic characteristics of changes in the nutritional status of adult population in the Omsk region during the implementation of Demography national project

Aim. To evaluate changes in nutritional status parameters among the adult population of the Omsk region during.Materials and Methods. The comparison of nutritional status parameters was conducted as a part of an experimental epidemiological study using a "before-after" design. The intervention consisted of activities carried out in the region from 2019 to 2023 under the federal project "Strengthening Public Health." In 2018, a representative sample (n = 241) was formed, stratified by age, gender, and residential area; in 2023, a similar sample (n = 506) was used. Nutritional status was assessed using somatometric, clinical, and laboratory methods.Results. We have documented a significant reduction in the prevalence of severe obesity (grades II-III, from 7.1 ± 1.1% to 2.4 ± 0.9%), and a trend towards a decrease in prevalence of underweight (from 5.4 ± 1.4% to 3.0 ± 0.8%; p = 0.078). In 2023, the proportion of individuals with overweight was 36.0 ± 2.1%, and 16.4 ± 2.4% of the adult population suffered from obesity. The prevalence of micronutrient deficiencies decreased significantly (p &lt; 0.001). In 2023, deficiencies in vitamin D (61.8 ± 1.7%), folates (50.0 ± 3.2%), vitamins B1 (26.6 ± 2.8%), B6 (36.7 ± 3.1%), and E (28.5 ± 2.9%), magnesium (32.0 ± 2.0%), zinc (27.2 ± 2.8%), copper (36.0 ± 3.1%), iron (25.0 ± 1.7%), and selenium (31.2 ± 3.9%) were the most common. Compared to 2018, the prevalence of deficiencies in vitamins D, E, B1, B6, and folates significantly decreased (p &lt; 0.05), while the provision of essential elements remained unchanged.Conclusion. The prevalence of various nutritional disorders among the adult population of the Omsk region reduced, as the implementation of the federal project «Strengthening Public Health» under the national project "Demography" improved the provision of vitamins.

Association of the Length of Service in the 24/48 Shift of Firefighters of the State Fire Service in Wroclaw on Selected Serum Biochemical Parameters of Nutritional Status.

The aim of the study was to evaluate the association of the quality of diet as calculated by the Nutrient Rich Food index (NRF9.3), and length of service (LS) (≤10 years vs. >10 years) with selected serum biochemical parameters, the proportions of different lipid profile fractions and advanced glycation endproduct (AGE) values of 108 firefighters from the State Fire Service in Wroclaw. The LS officers > 10 years had significantly higher total cholesterol (211.50 (184.00-254.00) vs. 184.00 (166.00-194.00)), LDL (123.75 (108.20-167.90) vs. 105.18 (90.24-119.00)) non-HDL (151.70 (132.00-196.70) vs. 122.00 (106.00-140.00)), triglycerides (118.50 (96.00-158.00) vs. 78.00 (67.00-103.00)) and lower HDL concentrations (51.30 (45.60-56.70) vs. 58.00 (51.70-66.10)) compared to firefighters in the LS ≤ 10 years group. Significant differences between the seniority groups were also noted for all lipid profile ratios. Regardless of the officers' seniority, systolic blood pressure was observed at the highest normal level of 134.4 ± 14.4 in the LS ≤ 10 years group and 139.5 ± 14.3 in the LS > 10 years group. Advanced glycation endproduct values were significantly dependent on diet quality, as expressed by the NRF9.3 index and on the TG/HDL ratio, but not on seniority. Diet quality, as expressed by the NRF9.3 index, had a significant association with GLU and FI levels, and components of the lipid profile between seniority groups. As NRF9.3 increased, TG/HDL, LDL/HDL, TC/HDL, and non-HDL/HDL ratios decreased. AGEs were significantly affected by NRF9.3 and significantly associated with TG/HDL. Firefighters' diets, as assessed by the NRF9.3 index, had a significant association with predictors of insulin resistance, diabetes, and cardiometabolic predictors between seniority groups. The nutritional education of firefighters (and other professional groups working irregularly), especially those with longer tenure (e.g., >10 years), is necessary to prevent the development of, e.g., CVD, MetS, and T2DM, which contribute towards a reduced ability to perform professional duties.

A correlation of serum fibroblast growth factor 21 level with inflammatory markers and indicators of nutritional status in patients with inflammatory bowel disease.

Fibroblast growth factor 21 (FGF21) is a stress-inducible hormone that regulates nutrient and metabolic homeostasis. Inflammatory state is one of the stimulators of FGF21 secretion. The aim of the study was to assess correlations between serum FGF21 level and inflammatory markers as well as nutritional status indicators in patients with inflammatory bowel disease (IBD). Fasting serum FGF21 level was measured using ELISA test in 105 IBD patients and 17 healthy controls. There were 31 subjects with active ulcerative colitis (UC), 16 with inactive UC, 36 with active Crohn's disease (CD), and 22 with inactive CD. Clinical and endoscopic activity of IBD was evaluated based on validated scales and indices. Fecal calprotectin, serum CRP, and selected parameters of nutritional status were tested in all patients. Serum FGF21 level was characterized by fluctuations depending on the IBD activity. FGF21 level was significantly higher in both active UC and CD compared to inactive phases of the diseases and to the controls. A correlation between FGF21 and fecal calprotectin levels was also found in UC and CD. Additionally, in CD, FGF21 level positively correlated with CRP level. In both UC and CD, a negative correlation was noted between FGF21 level and nutritional status parameters including cholesterol, protein, albumin levels, and BMI. The intensity of intestinal inflammation is related to FGF21 level, which correlates negatively with nutritional status indicators in IBD. The disturbances in FGF21 secretion may contribute to the multifactorial pathogenesis of malnutrition and weight loss in IBD patients.

The Assessment of the Nutritional Status among the Young-Old and Old-Old Population with Alimentary-Dependent Diseases.

Background and Objectives: Unhealthy nutrition can contribute to the development or progression of various alimentary-dependent diseases, including obesity, type 2 diabetes mellitus, metabolic syndrome, anaemia, and arterial hypertension. Young-old and old-old individuals often have diets deficient in essential vitamins, minerals, and macronutrients, characterized by high consumption of carbohydrate-rich foods and insufficient intake of plant-based products like vegetables and fruits. This study aims to identify key parameters of nutritional status among the young-old (aged 60-74 years) and old-old (aged 75-90 years) populations in central Kazakhstan, particularly in relation to specific alimentary-dependent diseases. Materials and Methods: The study involved 300 participants aged 60-90 years. The study incorporated a dietary questionnaire, food consumption records (such as 24 h recalls), and measurements of anthropometric indicators including weight and skinfold measurements. Results: Residents in the surveyed regions typically consumed food 3-4 times daily, with breakfast, lunch, and dinner being eaten at consistent times. A significant proportion of individuals, especially older adults, followed this meal schedule. About one-third ate before bedtime, and more than half believed they adhere to a specific diet. The mean BMI for men aged 60-74 years was 28.3 (95% CI: 20.1-43.2) and, for those aged 75-90 years, it was 29.0 (95% CI: 22.1-40.8). Caloric intake among individuals aged 60-74 was higher compared to those aged 75-90, with males consuming an average of 2372.7 kcal and females consuming 2236.78 kcal versus 2101.5 kcal for males and 2099.9 kcal for females in the older age group. Conclusions: The dietary patterns observed among old-old individuals were marked by excessive calorie intakes and imbalances in macronutrient composition, with a predominant emphasis on high-carbohydrate foods at the expense of essential nutrients like proteins, fats, and key vitamins (such as C, E, B vitamins) and minerals (such as potassium, calcium, and iron).

Potential Celiac Disease in Children: Health Status on A Long-Term Gluten-Containing Diet.

Potential celiac disease (PCD) is a clinical condition characterised by the presence of a positive CD-specific serology and a normal intestinal architecture. Asymptomatic PCD patients are generally advised to continue on a gluten-containing diet (GCD), but long-term risks of this approach have never been explored. In the present study, we aimed to investigate nutritional and autoimmune complications possibly developing overtime in a cohort of asymptomatic PCD children on a GCD. We compared children's parameters of growth, nutritional status, and autoimmunity between the time of diagnosis and on the occasion of their last medical check, after a long-term gluten-containing diet. Altogether, we collected data from 171 PCD children with a mean follow-up time of 3 years (range 0.35-15.3 years). During follow-up, although patients did not reduce their amount of daily gluten intake, their anti-tissue transglutaminase (anti-TG2) antibodies spontaneously and significantly decreased. Most parameters analysed had not changed during follow-up (height centile, ferritin, albumin, cholesterol, calcium, alkaline phosphatase, parathormone, and vitamin D) or even improved significantly (weight and BMI centile, haemoglobin, blood iron, HDL, glycaemia, and HbA1C, p < 0.05), always remaining within the limit of normality. Equally, autoantibodies for other concomitant autoimmune disorders did not increase overtime. Similar results were obtained excluding from analysis patients who had stopped producing anti-TG2 and those with a follow-up time < 3 years. Our pilot study has provided reassuring results regarding the maintenance of a gluten-containing diet in asymptomatic PCD children, even when long-term follow-up was considered.

A Prospective, Observational Study of the Effect of a High-Calorie, High-Protein Oral Nutritional Supplement with HMB in an Old and Malnourished or at-Risk-of-Malnutrition Population with Hip Fractures: A FracNut Study.

Hip fractures are prevalent among older people, often leading to reduced mobility, muscle loss, and bone density decline. Malnutrition exacerbates the prognosis post surgery. This study aimed to evaluate the impact of a 12-week regimen of a high-calorie, high-protein oral supplement with β-hydroxy-β-methylbutyrate (HC-HP-HMB-ONS) on nutritional status, daily activities, and compliance in malnourished or at-risk older patients with hip fractures receiving standard care. A total of 270 subjects ≥75 years of age, residing at home or in nursing homes, malnourished or at risk of malnutrition, and post hip fracture surgery, received HC-HP-HMB-ONS for 12 weeks. Various scales and questionnaires assessed outcomes. During the 12 weeks of follow-up, 82.8% consumed ≥75% of HC-HP-HMB-ONS. By week 12, 62.4% gained or maintained weight (+0.3 kg), 29.2% achieved normal nutritional status (mean MNA score +2.8), and 46.8% improved nutritional status. Biochemical parameters improved significantly. Subjects reported good tolerability (mean score 8.5/10), with 87.1% of healthcare providers concurring. The administration of HC-HP-HMB-ONS markedly enhanced nutritional status and biochemical parameters in older hip-fracture patients, with high compliance and tolerability. Both patients and healthcare professionals expressed satisfaction with HC-HP-HMB-ONS.

Machine learning approach to assess the association between anthropometric, metabolic, and nutritional status and semen parameters.

Many lifestyle factors, such as nutritional imbalance leading to obesity, metabolic disorders, and nutritional deficiency, have been identified as potential risk factors for male infertility. The aim of this study was to evaluate the relationship between semen parameters and anthropometric, metabolic and nutritional parameters. Relationship was first assessed individually, then after the application of a previously constructed and validated machine learning score that allows their combination. Anthropometric, metabolic, antioxidant, micronutrient, and sperm parameters from 75 men suffering from idiopathic infertility from four infertility centers in France (Jean-Verdier ART Center Hospital, Bondy; North Hospital ART Center, Saint-Étienne; Navarre Polyclinic ART Center, Pau; and Cochin Hospital ART Center, Paris) between September 2009 and December 2013 were collected. After assessing standard correlation analysis, a previously built machine learning model, providing a score ranging from 0 (the poorest) to 1 (the most favorable), was calculated for each man in the study cohort. This machine learning model, which separates infertile/fertile men with unexplained infertility on the basis of their bioclinical signature, provides a more holistic evaluation of the influence of the considered markers (anthropometric, metabolic, and oxidative status). We observed a significant correlation of some anthropometric, metabolic, and nutritional disorders with some sperm characteristics. Moreover, an unfavorable machine learning score was associated with a high level of sperm DNA fragmentation. Favorable anthropometric, metabolic, and oxidative patterns, which may reflect an appropriate lifestyle, appear to positively impact overall health, in particular reproductive function. This study, consistent with previous publications, suggests that beyond semen quality parameters, in an essential assessment of male fertility, other key factors should be taken into account. In this regard, the application of emerging artificial intelligence techniques may provide a unique opportunity to integrate all these parameters and deliver personalized care.

Association between Blood Parameters of Nutritional Status and Functional Status in Extreme Longevity.

The relationship between functional and nutritional status in the geriatric population remains an issue of debate and there is a gap in the knowledge regarding this field in long-lived individuals. The main aim of this study was to assess the association between selected blood parameters of nutritional status and functional status in extreme longevity. The inclusion criteria were centenarians above 100 years of age who were examined at their homes, and blood samples were collected. The study group consisted of 170 individuals (25 men and 145 women, median age 100.75 years [100.29-101.58]). Total protein and albumin serum concentration was significantly lower in long-lived individuals with severe functional decline compared to individuals with preserved functional status, p = 0.000001 and p = 0.0000, respectively. Iron serum level was significantly higher in the group with preserved functional status, p = 0.04. Preserved functional status was positively correlated with total protein serum concentration (p = 0.000), albumin concentration (p = 0.000), and iron serum level (p = 0.029). A negative correlation was stated between c-reactive protein (CRP) and functional status (p = 0.032). Univariable logistic regression analysis showed that the functional status of long-lived individuals depends on total protein (OR 2.89, CI 95% [1.67-5.0]) and albumin concentrations (OR 2.34, CI 95% [1.39-3.92]). Multivariable backward stepwise logistic regression analysis showed that a total protein concentration was the only variable independently related to the preserved functional status (OR 3.2, 95% Cl [1.8-5.67]). In long-lived individuals, the total serum protein and albumin levels are lower in centenarians with severe functional decline, and they correlate with functional status. Total protein serum concentration is the only factor independently related to the preserved functional status in extreme longevity.

Are the nutritional status and growth parameters of children with juvenile idiopathic arthritis akin to their healthy peers? A single-center experience

ObjectiveProper nutrition is a significant contributor to growth achievement in patients with juvenile idiopathic arthritis (JIA). In this study, the aim was to analyze the growth parameters and nutritional status of children with JIA and then compare them with their healthy peers. MethodsA cross-sectional study was conducted with 54 patients with JIA and the same number of healthy peers. Growth parameter z-scores and nutrient distributions were analyzed and compared with a control group and among disease subgroups. ResultsWhile the average height in the control group was significantly greater than in the patient group, there was similarity in terms of body weight and body mass index (BMI) (P < 0.001, P = 0.33, P = 0.14, respectively). Body weight and BMI z-scores of patients with high disease activity at the most recent visit were significantly lower (P = 0.03, P = 0.01, respectively). Both groups had similar energy and protein requirement–meeting percentages (P = 0.62, P = 0.51). JIA atients had higher carbohydrate intake (P = 0.04), and fat intake was higher in controls (P = 0.02). Energy obtained from junk food was higher in patients with entesitis-related arthritis (ERA) compared to oligoarticular JIA and polyarticular JIA (P = 0.03). Micronutrient intake in the ERA group was significantly lower for vitamin E, C, and folate (P = 0.02, P = 0.03, P < 0.001). ConclusionIn our cohort, patients had a lower height score. As they have a diet characterized by adequate energy/protein, carbohydrate, and high fat intake, this may be a reflection of disease activity. Although some of the micronutrient intakes were less than normal in both groups, significant deficiencies were identified in the ERA group.

Nutritional status in advanced pancreatic cancer

Background. Exocrine pancreatic insufficiency (EPI) occurs in most patients with advanced pancreatic cancer (PC) and even more often when a tumor is localized in the head of the pancreas. However, insufficient attention is paid to the diagnosis of EPI and assessment of nutritional status, which negatively affects the results of treatment.&#x0D; Materials and methods. One hundred fifty eight patients with primary diagnosed locally advanced and metastatic PC were included in the retrospective study. We used the calculation of the odds ratio with 95% CI with an assessment of the p value using the Pearson ÷2 test to compare the incidence of clinical and laboratory parameters of nutritional status with values below the lower limit of normal (LLN) depending on the location of the tumor in the pancreas.&#x0D; Results. Fecal elastase test was performed in only 19 (12%) patients. In this group, the incidence of EPI was 73.6%. Pancreatic enzyme replacement therapy in the minimal sufficient dose was prescribed in 17.1% of the general cohort. The level of hemoglobin, erythrocytes and albumin below the LLN was found in patients with the tumor in the pancreatic head, respectively, 2.742 (95% CI 1.27–5.92), 3.788 (95% CI 1.554–9.232) and 9.767 (95% CI 1.255–76.027) times more often than in patients with cancer in the body-tail of the pancreas. In patients with the tumor in the pancreatic head, the lower levels of hemoglobin (median 125 g/l vs 132 g/l, respectively), erythrocytes (4.19 mil/μl vs 4.51 mil/μl), total protein (69.6 g/l vs 71.5 g/l), and albumin (40.1 g/l vs 42 g/l), as well as the values of nutritional indices: prognostic nutritional index, nutritional risk index, hemoglobin, albumin, lymphocyte and platelet ratio index, and prognostic immune nutritional index were observed.&#x0D; Conclusion. Diagnosis and treatment of EPI remains inadequately attended. The values of nutritional status parameters in patients with PC in the head are lower than in patients with a tumor in the body-tail of the pancreas, which reflects the contribution of EPI.

Probiotic supplementation for 24 weeks in patients with non-alcoholic steatohepatitis: the PROBILIVER randomized clinical trial.

Considering the increasing prevalence of non-alcoholic steatohepatitis (NASH) and treatment gaps, this study aimed to evaluate the effect of probiotic supplementation on liver function markers, nutritional status, and clinical parameters. This double-blind, randomized clinical trial (ClinicalTrials.gov ID: NCT0346782) included adult outpatients with biopsy-proven NASH. The intervention consisted of 24 weeks of supplementation with the probiotic mix Lactobacillus acidophilus (1 × 109 CFU) + Lactobacillus rhamnosus (1 × 109 CFU) + Lactobacillus paracasei (1 × 109 CFU) + Bifidobacterium lactis (1 × 109 CFU), or placebo, twice a day. The following parameters were evaluated: demographic and clinical data, transient elastography (FibroScan), liver enzymes, NAFLD fibrosis score, fatty liver index, laboratory assessment, serum concentration of toll-like receptor-4 (sTLR-4) and cytokeratin 18 (CK-18), anthropometric data, dietary intake, and physical activity. Regarding data analysis, the comparison between the groups was based on the delta of the difference of each variable analyzed (value at the end of treatment minus the baseline value) using the t-test for independent samples or the Mann-Whitney U-test. Forty-four patients with NASH completed the trial (51.4 ± 11.6 years). At baseline, 87% of participants had a mild liver fibrosis degree on biopsy, normal values of liver enzymes, transient elastography values consistent with grade 1 fibrosis in both groups, increased waist circumference (WC), a BMI of 30.97 kg/m2, and 76% presented with metabolic syndrome (MetS). After the intervention, no differences were observed between the probiotic and placebo groups in terms of MetS, WC, BMI scores, or liver enzyme levels (p > 0.05 for all). The elastography values remained consistent with grade 1 fibrosis in both groups. Although CK-18 was reduced in both groups, a larger effect size was noted in the probiotic group (D = 1.336). sTLR-4 was also reduced in both groups, with no difference between groups (p = 0.885). Intervention with probiotics in the early stages of NASH demonstrated no significant change in hepatic and clinical parameters. ClinicalTrials.gov, identifier NCT0346782.

An Evaluation of the Effectivity of the Green Leaves Biostimulant on Lettuce Growth, Nutritional Quality, and Mineral Element Efficiencies under Optimal Growth Conditions.

The use of biostimulants is becoming a useful tool for increasing crop productivity while enhancing nutritional quality. However, new studies are necessary to confirm that the joint application of different types of biostimulants, together with bioactive compounds, is effective and not harmful to plants. This study examined the impact of applying the biostimulant Green Leaves, comprising Macrocystis algae extract and containing a mixture of amino acids, corn steep liquor extract, calcium, and the bioactive compound glycine betaine. The effect of applying two different doses (3 and 5 mL L-1) of this biostimulant was evaluated on lettuce plants, and growth and quality parameters were analyzed along with photosynthetic efficiency, nutritional status, and nutrient efficiency parameters. The application of Green Leaves improved plant weight (25%) and leaf area and enhanced the photosynthetic rate, the accumulation of soluble sugars and proteins, and the agronomic efficiency of all essential nutrients. The 3 mL L-1 dose improved the nutritional quality of lettuce plants, improving the concentration of phenolic compounds and ascorbate and the antioxidant capacity and reducing NO3- accumulation. The 5 mL L-1 dose improved the absorption of most nutrients, especially N, which reduced the need for fertilizers, thus reducing costs and environmental impact. In short, the Green Leaves product has been identified as a useful product for obtaining higher yield and better quality.

Effectiveness of Preoperative Immunonutrition in Improving Surgical Outcomes after Radical Cystectomy for Bladder Cancer: Study Protocol for a Multicentre, Open-Label, Randomised Trial (INu-RC).

Radical cystectomy (RC) with pelvic lymph node dissection is the standard treatment for patients with limited-stage muscle-invasive bladder cancer. RC is associated with a complication rate of approximately 50-88%. Immunonutrition (IMN) refers to the administration of substrates, such as omega-3 fatty acids, arginine, glutamine, and nucleotides, that modulate the immune response. IMN has been associated with improved outcomes following surgery for esophagogastric, colorectal and pancreatic cancer. In this paper, we describe a study protocol for a multicentre, randomised, open-label clinical trial to evaluate the effect of IMN in patients undergoing RC for bladder cancer. A 7-day preoperative course of IMN is compared with a standard high-calorie high-protein oral nutritional supplement. The primary outcome of this study is the rate of complications (infectious, wound-related, gastrointestinal, and urinary complications) in the first 30 days after RC. Secondary outcomes include time to recovery of bowel function and postoperative mobilisation, changes in muscle strength and body weight, biochemical modifications, need for blood transfusion, length of stay, readmission rate, and mortality. The results of this study may provide new insights into the impact of IMN on postoperative outcomes after RC and may help improve IMN prescribing based on patient nutritional status parameters.

4-week results of “Linni Slim” synbiotic in patients with metabolic syndrome

The purpose of the study is to evaluate the efficacy and safety of a synbiotic in a short-term course (4 weeks), including an extract of garcinia cambogia, probiotics and prebiotics in patients with MS Materials and methods. The pilot, observational, open-label, non-randomized prospective clinical trial included 20 patients with metabolic syndrome (13 males and 7 females, Me age 42 years). A biologically active food supplement (synbiotic) “LINNI SLIM” (PharmlandBIO, Republic of Belarus) was used, including an extract of garcinia cambogia (containing 60% hydroxycitric acid, 0.03 g/g), probiotic strains of the genus Bifidobacterium (B. bifidum, B. animalis ssp lactis, B. longum ssp longum) CFU/g) - 0.066x 109 CFU/g and Lactobacillus (L. Acidophilus, L. Plantarum, L. Rhamnosus, L. Casei, L. Crispatus, L. Reuteri, L. Gasseri) - 0,134 x 109 CFU/g; prebiotics (psyllium husk, microcrystalline cellulose, linseed fiber, inulin, fenugreek). The daily dose of garcinia cambogia is 0.3 g, dietary fiber is 5.16 g. The parameters of nutritional (including bioimpedance analysis) and metabolic status, safety (hepatotoxic effects) and tolerability (gastrointestinal symptoms, 2H-breath test with lactulose and glucose) were evaluated. Results. There was a significant decrease in serum concentrations of insulin (15.2 [9.7; 23.0] Vs 10.9 [6.6; 16.4] mcU/ml; p=0.002), triglycerides (2.1 [1.4; 2.3] Vs 1.2 [1.2; 1.9] mmol/l; p=0.002), values of the HOMA-IR index (3.77 [2.54; 6.08] Vs 2.50 [1.44; 3.65]; p=0.003) without deviation of serum biomarkers of liver damage. Good tolerability and safety of “LINNI SLIM” was established: the appearance of symptoms of dyspepsia, stool disorders requiring the abolition of dietary supplements, deviations in the results of the 2H-breath test were not registered. Conclusion. A 4-week course of using the “LINNI SLIM” synbiotic at a daily dose of 10 grams has a positive effect on the metabolic status of the body (reduction of insulin, triglycerides, HOMA-IR - insulin resistance index) with satisfactory safety parameters. The effectiveness and improvement of “metabolic health” allows the use of the “LINNI SLIM” synbiotic in the initial therapy for reducing (controlling) body weight in people suffering from metabolic syndrome on the background of obesity.

The influence of nutritional status and associated factors on the quality of life among COVID-19 patients in Saudi Arabia: A cross-sectional study

BackgroundCOVID-19 adversely affects the nutritional characteristics of patients which may negatively impact their quality of life (QOL). The current study determined the association between the nutritional status of COVID-19 patients, its impact on their QOL, and the factors that affected patients' QOL. MethodsA cross-sectional study was conducted at Al Madinah Al Munawarah in Saudi Arabia. Patients confirmed with COVID-19 infection by a nucleic acid-positive test and identified as acute severe or acute non-severely ill were enrolled. The World Health Organization Quality of Life Questionnaire (WHO-BREF QOL) was used to assess the patients' QOL, and nutritional status was assessed using the Malnutrition Screening Tool. Demographic characteristics, food intake, and body mass index (BMI) were also assessed. Data was analyzed using SPSS version 28. Results515 patients were enrolled, with 391 (76%) having acute non-severe symptoms. Patients (15%) were malnourished and suffered from loss of appetite (32%), low food intake (19.4%) and weight loss (16%). Most patients were satisfied or very satisfied with their health (80.2%), and 76.2% rated their QOL as good or very good. Loss of appetite negatively impacted the physical (p = 0.004, 95% CI 0.086, 0.458) and psychological (p = 0.021, 95% CI 0.034, 0.405) QOL domains. Also, decreased food intake affected patients' physical (p = 0.034, 95% CI 0.018, 0.458) QOL domain. Greater weight loss influenced the psychological (p = 0.005.95% CI 0.002, 0.049) QOL domain. ConclusionsPoor nutritional status among COVID-19 patients was associated with adverse health outcomes and impaired QOL. Nutritional interventions should focus on patients with poor nutritional status or nutrition-related parameters such as weight loss, and loss of appetite which will help improve their QOL.

Nutritional Status Predicts the Length of Stay and Mortality in Patients Undergoing Electrotherapy Procedures.

(1) Background: Nutritional status is a factor that impacts the patients' outcomes in various medical conditions including cardiovascular patients or surgical procedures. However, there is limited available information about its impact on the short-term outcomes of cardiac implantable electronic device (CIED) implantations. This study aimed to assess the relationship between nutritional status, complications, mortality risk, and length of stay at the hospital in patients undergoing CIED implantations. (2) Material and Methods: 588 patients who underwent CIED implantation in 2022 and 2023 were included in the retrospective analysis. The nutritional status assessment was performed using NRS 2002 and BMI. The implanted devices were single-chamber pacemakers (n = 82), dual-chamber pacemakers (n = 329), one-chamber ICDs (n = 83), dual-chamber ICDs (n = 19), CRT-P (n = 19), and CRT-D (n = 56). (3) Results: The regression analysis showed that the NRS 2002 score predicted the length of stay (age-adjusted: β = 1.02, p = 0.001) among the CIED-implanted patients. The CRT-D subgroup was particularly responsible for this relationship (β = 4.05, p = 0.003 after age adjustment). The analysis also revealed significant differences between the NRS 2002 score in the in-hospital death subgroups (1.75 ± 1.00 points for deaths vs. 1.00 ± 1.00 points for survivors; p = 0.04). There were no significant differences in nutritional status parameters regarding early complications subgroups. (4) Conclusions: This study showed that nutritional risk assessed with NRS 2002 is a predictor of length of stay (particularly for CRT-D) and mortality among patients undergoing CIED implantations. The results of the analysis point out the impact of patients' nutritional status on short-term outcomes of CIED implantations, particularly in CRT-D implants where 1 NRS 2002 point was a predictor of a mean 4.05 days (77.2%) longer hospitalization.

Poor diet quality is associated with biochemical parameters of protein nutritional status after Roux-en-Y gastric bypass

ObjectiveTo assess diet quality and its association with body and biochemical parameters in patients who underwent Roux-en-Y gastric bypass (RYGB). MethodsProspective observational study with individuals of both sexes subjected to RYGB. Body composition, biochemical parameters, and diet quality were assessed before and six months after RYGB. Diet quality was assessed by the Healthy Eating Index (HEI). Data were analyzed by the paired t-test or Wilcoxon signed-rank test, with a significance level of 5%. Spearman's correlation and simple linear regression were performed between variables. ResultsThe final sample included 34 patients. Their diet was classified as poor before and 6 mo after RYGB. BMI, fat mass, fat-free mass, waist perimeter, serum total protein, transthyretin, alpha-1-acid glycoprotein, and C-reactive protein decreased significantly (P < 0.05). Variations in the HEI score and caloric intake were associated with serum albumin and transthyretin (P < 0.05). ConclusionPoor diet quality was present before and six months after RYGB, and the study data suggest that poor diet quality is associated to a risk of loss of lean body mass and visceral protein six months after RYGB.

Determination of nutrition index and correlation with activity of lupus nephritis

Background/Aim. Lupus nephritis (LN), as an immuno-inflammatory kidney lesion, and the most serious manifestation of systemic lupus erythematosus (SLE), is accompanied by a disorder of the nutritional status of patients. Our goal was to determine the importance of determining and the association of parameters of nutritional status - nutritional risk index (NRI), prognostic nutritional index (PNI) and control nutritional status (CONUT) with standard parameters of LN activity. Methods. The clinical study included a group of 92 subjects. 67 patients had LN (34 patients had LN active disease , the LNa group, and 33 patients were in LN remission, the LNr group) and 25 healthy subjects (control group). In addition to standard laboratory parameters, LN activity parameters, derived parameters were also determined: PNI=10 x albumin value (g/dL) + 0.005 x number of peripheral lymphocytes (/mm3); NRI = 1.519 ? serum albumin, g/dL + 41.7 ? weight (kg)/ideal body weight ( kg); CONUT score = serum albumin + total lymphocyte score + total cholesterol. Results. A statistically significant difference between all three groups was observed for the PNI (p=0.001) and for the CONUT score (p=0.000), while the NRI did not have a significant difference. Statistical significance was found for the correlation of PNI in the LNa group, with the levels of albumin, complement C3 and C4, and a significant negative correlation with the value of anti-ds-DNA Ab. NRI correlated with statistical significance only with proteinuria in the LNa group. CONUT showed significant correlations with the most of the parameters for disease activity: negative correlation with albumin and complement C3 (p = 0.000), and positive correlation with anti -double strand (ds) - DNA Antibody (p=0.002),with Systemic Lupus Erythematosus Disease Activity Index/renal (SLEDAI/r) and with proteinuria/24 hrs (p=0.000). Conclusion. In our group of patients, a statistically significant difference was observed between the groups for the nutrition score CONUT. and the PNI. Their correlation with standard parameters of active disease was significant for most parameters in the group of patients with LNa.
