Predictors of mortality among multidrug-resistant tuberculosis patients after decentralization of services in Tanzania from 2017 to 2019: retrospective cohort study

BackgroundMultidrug-resistant tuberculosis (MDR-TB) presents persistent global health challenges, characterized by low treatment success rates among patients enrolled for treatment. The World Health Organization recommends decentralization to improve outcomes. This study aims to assess predictors of mortality among MDR-TB patients after decentralization of services in Tanzania. This was a retrospective cohort study involving all MDR-TB patients enrolled in treatment in all 31 regions in Tanzania from 2017 to 2019. The overall mortality rate among MDR-TB patients was calculated using the incidence rate. Additionally, independent factors of MDR-TB mortality were determined using multivariable cox proportional hazards models.ResultsThe study followed 985 patients for a total of 12,929 months. During this time, it found that approximately 12 out of every 1000 patients died each month. Specifically, the death rates were about 18 out of 1000 patients at 6 months, 8 out of 1000 at 12 months, and 7 out of 1000 at 24 months. Patients who had both MDR-TB and HIV, as well as those who were malnourished, had a lower chance of surviving at 6, 12, and 24 months. Malnourished patients had almost three times the risk of dying [adjusted hazard ratio (aHR) 2.96, with a 95% confidence interval (CI) of 2.10–4.19], while those with HIV had nearly double the risk [aHR 1.91, with a 95% CI of 1.37–2.65].ConclusionIn summary, our study on MDR-TB patient outcomes in Tanzania between 2017 and 2019 reveals a pattern of high mortality rates within the first 6 months of treatment. Furthermore, malnutrition and HIV co-infection were found to be significant predictors of mortality. To decrease mortality, it is crucial to closely monitor patients during the initial 6 months of treatment, especially those who are malnourished or co-infected with HIV, and ensure they receive appropriate and timely care. Additionally, further investigation is needed to find out what may be contributing to possible rise in mortality rate.

Unveiling the impact: Exploring malnutrition rates in patients with cancer and its association with anticancer treatments.

189 Background: Malnutrition is a common cause of morbidity and mortality in patients with cancer. Malnutrition is seen in 40 to 80% of patients with cancer. Recent literature has shown loss of lean body mass in cancer population can be an independent factor for poorer outcomes. Anorexia, the loss of appetite has been either secondary to the disease itself or as a side effect of treatment. The mechanism of anorexia development is due to physiologic alteration in metabolism during carcinogenesis. Hence, it becomes important to screen for malnutrition in all patients with diagnosis of cancer. Methods: This single-center cohort study, conducted between January 15, 2024, and February 9, 2024, involved 106 patients receiving outpatient oncology care. Patients aged 18 to 90 years who consented to participate were administered the Mini Nutritional Assessment (MNA) questionnaire at the oncology registration desk. Exclusion criteria included patients with a dietician and those with pure nonmalignant hematological diagnoses. Data analysis comprised identifying patients at risk of malnutrition (8-11 points) or malnourished (0-7 points) using the MNA scale, followed by retrospective chart review. Primary outcomes focused on identifying prevalent cancer types among malnourished or at-risk patients, while secondary outcomes included comparing malnutrition proportions among different treatment groups and assessing gastrointestinal tract metastases and common causes of malnutrition. Results: The data encompassed 106 patients, among whom 29 (27.3%) were identified as at risk of malnutrition, while 9 (8.4%) were malnourished. Notably, a majority of at-risk or malnourished patients (60.5%) were classified as overweight or obese. The most prevalent cancers among these patients were breast cancer (26.3%), genitourinary cancer (23.6%), and gastrointestinal cancer (18.4%). Chemotherapy use was noted in 16 (42.1%) patients, immune checkpoint inhibitor treatment in 12 (31.5%), and a combination of both in 7 (18.4%). Gastrointestinal metastasis was observed in 5 (13.1%) patients. Among those at risk of malnutrition, the primary contributing factors identified were tumor impact and location (63.1%), diarrhea (18.4%), and fatigue (18.4%). Conclusions: The study underscores the significant prevalence of malnutrition risk among cancer patients, emphasizing the importance of systematic screening during outpatient oncology follow-ups.

High-Protein Nutritional Supplements Improve Nutritional Status in Malnourished Patients with Systemic Sclerosis.

(1) Background: Impaired nutritional status in systemic sclerosis (SSc) is prevalent. (2) Objective: This study aimed to identify pre-cachexia and malnutrition in SSc patients and to estimate the effectiveness of a high-protein oral nutritional supplement (ONS) in improving their nutritional status. (3) Materials and methods: The SSc population comprised 56 patients and a control group of 49 healthy persons. After a baseline clinical evaluation, bioelectrical impedance analysis (BIA), and laboratory tests, SSc patients were divided into well-nourished, pre-cachectic, and malnourished categories. SSc patients with a nutritional disbalance received a high-protein ONS once daily for 3 months. Patients were reassessed at 3 and 12 months after inclusion in the study. (4) Results: SSc patients, in comparison to the control group, had a significantly lower seven-point SGA value [6(0) vs. 7(1), p < 0.001)], lean tissue mass [LTM, 35.1 (10.5) vs. 40.1 (10.10), p = 0.008], and lean tissue index [LTI, 13.5 (3) vs. 14.9 (4), p = 0.009]. Of the 56 SSc patients, 40 (71.4%) were well nourished, 5 (8.9%) had pre-cachexia, and 11 (19.7%) were malnourished. A high-protein ONS in the pre-cachexia group stabilized the SGA value, anthropometric measurements, and BIA after 3 and 12 months. In malnourished patients, it significantly improved the SGA value [5(0) vs. 6(0), p = 0.002], LTI [12.1 (2.1) vs. 12.7 (3.2), p = 0.021] and LTM [31.1 (7.7) vs. 35.1 (9.1), p = 0.021], and that effect remained stable at 12 months. (5) Conclusion: Malnutrition is a common complication of SSc that can be improved with nutritional intervention.

Malnutrition in Amyotrophic Lateral Sclerosis: Insights from Morphofunctional Assessment and Global Leadership Initiative on Malnutrition Criteria.

Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease frequently accompanied by malnutrition due to weight loss, increased energy expenditure, and muscle mass loss. This study aimed to evaluate morphofunctional assessment tools as predictors of malnutrition and to investigate their relationship with muscle status and disease severity in ALS patients. A cross-sectional study was conducted with 45 ALS patients at the San Cecilio University Hospital in Granada. Malnutrition was assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Morphofunctional assessment was performed using Bioimpedance Vectorial Analysis (BIVA), handgrip strength (HGS), and Short Physical Performance Battery (SPPB). Malnutrition prevalence was 38% according to GLIM criteria. Significant differences were observed between malnourished and non-malnourished groups in age (70 ± 9 vs. 62 ± 10 years, p = 0.01), sex (female prevalence: 58.8% vs. 25.0%, p = 0.02), dysphagia prevalence (83% vs. 29%, p < 0.001), PEG/PRG use (35.3% vs. 3.6%, p = 0.01), and ALSFRS-R scores (30 ± 12 vs. 34 ± 12, p = 0.02). Malnourished patients had lower values in anthropometric measurements, muscle mass obtained by BIVA, and phase angle (PA) (4.05 ± 0.8° vs. 5.09 ± 0.8°, p < 0.001). No significant differences were found in muscle strength or functional status. PA showed significant correlations with muscle strength (r = 0.52, p < 0.001) and muscle mass measures (r = 0.48, p < 0.001). Moreover, PA was associated with poorer disease progression and physical performance. In our sample, BIVA metrics such as PA (<4.3°), SPA (<-0.8), body cell mass (<9.2 kg/m), and extracellular water (>49.75%) were identified as malnutrition risk factors. The study underscores the critical importance of comprehensive morphofunctional assessment and the use of advanced diagnostic criteria, for early identification and intervention in malnutrition among people with ALS. Further research is warranted to validate these findings and develop targeted nutritional strategies into routine clinical practice.

Validation of the Global Leadership Initiative on Malnutrition Criteria for Predicting Adverse Outcomes in Acute Pancreatitis.

The Global Leadership Initiative on Malnutrition (GLIM) has proposed criteria for the diagnosis of malnutrition. No studies validated the GLIM criteria in acute pancreatitis (AP). The present study aimed to validate the predictive capacity of GLIM criteria for adverse outcomes in AP patients. Clinical data of 269 patients with AP were analyzed retrospectively. The Nutritional Risk Screening 2002 (NRS2002) was chosen as the screening tool. Multivariate logistic regression analyses evaluated the adverse clinical outcomes in malnourished patients. Overall, 160 patients (59.5%) were at nutritional risk and 38 (14.1%) were malnourished. Reduced muscle mass/ low bodymassindex + inflammation combinations contributed most to malnutrition overall and in each subgroup. The malnourished group had lower hemoglobin, neutrophils, albumin, total cholesterol, and triglycerides than the well-nourished group. The malnourished group had higher hospitalization costs (CNY, 11319.34 vs 9258.22, p <0.001) and more local complications (34.2% vs 14.7%, p =0.009) than the well-nourished group. There was an interaction between malnutrition and overweight/obesity on local complications (p for interaction = 0.023). Multivariate logistic regression showed malnutrition was significantly associated with local complications (OR 12.2, 95% CI: 2.51-59.37), infectious complications (OR 9.95, 95% CI: 1.25-79.44) and composite adverse outcome (OR 4.78, 95% CI: 1.05-21.73) in the overweight/obesity subgroup. There was no association between malnutrition and the rate of various adverse outcomes in the non-overweight/obesity subgroup. Additionally, we observed an association between malnutrition and composite adverse outcome (OR 6.75, 95% CI: 1.49-30.68) in patients <70 years only in females. Malnourished AP patients were more likely to have adverse outcomes than well-nourished patients. Malnutrition was associated with various adverse outcomes only in the overweight/obesity subgroups.

Variations in vertebral muscle mass and muscle quality in adult patients with different types of cancer

ObjectivesAssessment of malnutrition-related muscle depletion with computed tomography (CT) using skeletal muscle index (SMI) and muscle radiation attenuation (MRA) at the third lumbar vertebra is well validated. However, SMI and MRA values at other vertebral locations and interchangeability as parameters in different types of cancer are less known. We aimed to investigate whether adult patients with different types of cancer show differences in SMI and MRA at all vertebral levels. MethodsWe retrospectively analyzed CT images from 203 patients:120 with head and neck cancer, esophageal cancer, or lung cancer (HNC/EC/LC) and 83 with melanoma (ME). Univariate and multivariate linear regression analyses determined the association between SMI (cm²/m2) and MRA (Hounsfield units) and cancer type at each vertebral level (significance corrected for multiple tests, P ≤ 0.002). The multivariate analyses included age, sex, cancer stage, comorbidity, CT protocol, and body mass index (BMI) (MRA analyses). ResultsSMI was lower in the HNC/EC/LC group versus the ME group at all vertebral levels, except C4 through C6 in the multivariate analyses. Female sex was associated with lower SMI at almost all levels. MRA was similar at most vertebral levels in both cancer groups but was lower at C1 through C4, T7, and L5 in the multivariate analyses. Use of contrast fluid and BMI were associated with higher MRA at all vertebral levels except T8 to T9 and C1 to C2, respectively. ConclusionsSMI, but not MRA, was lower in HNC/EC/LC patients than in ME patients at most vertebral levels. This indicates that low muscle mass presents itself across the various vertebral muscle areas. MRA may less consistently mark muscle depletion in malnourished patients.

Investigation of nutrition status and analysis of 180-day readmission factors in elderly hospitalized patients with COPD

Background and objectiveMalnutrition is prevalent among elderly patients with COPD, who also experience a high rate of readmission. Therefore, it is imperative to investigate the nutrition status of these patients, identify risk factors for readmission, and offer insights for clinical management. To achieve this, a cross-sectional study was conducted to investigate factors influencing nutrition status using GLIM criteria and explore the 180-day readmission factors among hospitalized elderly COPD patients.Methords and resultsThe data were collected from a hospital in Southwest China, encompassing a cohort of 319 eligible patients. Among elderly hospitalized COPD patients, the prevalence of malnutrition was 49.53% (158/319). Multivariate logistic regression revealed malnutrition (OR = 3.184), very severe airway obstruction (OR = 3.735), and Number of comorbidities ≥ 3 (OR = 5.754) as significant risk factors for 180-day readmission.ConclusionsThese findings suggest that malnutrition is a prevalent issue among elderly hospitalized patients with COPD and constitutes one of the risk factors contributing to the 180-day readmission rate. Therefore, timely identification and treatment for malnourished patients are crucial.

Adherence to the Mediterranean Diet Mitigates Inflammation and Hospital Stay in Frail Elderly Patients: A Moderation Analysis.

We conducted two-way ANOVA and multiple regression analysis to evaluate the effects of nutritional status and MD adherence on the CRP levels and LOS in a cohort of 117 frail elderly patients aged 65 years or older. Patients with cancer or acute infection were excluded. Adherence to the MD was assessed using the 14-item PREDIMED questionnaire. Significant interactions were found between nutritional status and MD adherence for both the CRP and LOS. The patients with low-level MD adherence and a poor nutritional status exhibited higher CRP levels and longer hospital stays compared to those with high MD adherence. Specifically, a statistically significant interaction was observed for the CRP (F (1, 113) = 7.36, p = 0.008) and LOS (F (1, 113) = 15.4, p < 0.001), indicating the protective effect of high-level MD adherence. Moderation analysis confirmed that high-level MD adherence mitigates the adverse effects of malnutrition on both the inflammatory response and LOS. These findings highlight the importance of promoting the MD, particularly in malnourished elderly patients, to improve health outcomes and reduce hospitalization duration. Further longitudinal studies are warranted to establish causality and explore the underlying mechanisms.

Evaluation of five nutritional scores as predictors of postoperative outcome following pancreatic resection: A prospective, single-center study

Background and aimsPatients undergoing pancreatic resection are commonly malnourished. It is still unclear whether nutritional scores reliably predict postoperative outcomes after pancreatic resection. This study evaluated whether five commonly used preoperative nutritional screening scores predicted severe complications and length of stay. MethodsPatients scheduled for pancreatic resection (pancreatoduodenectomy, distal and total pancreatectomy) at a national referral center for pancreatic surgery from September 2022 to June 2023 were prospectively screened for malnutrition with MNA, MUST, SGA, SNAQ, and NRS2002 scores. Postoperative complications were classified using the Clavien-Dindo classification. #NCT05608538. ResultsThree hundred patients were enrolled, including 168 pancreatoduodenectomies (56%), 102 distal pancreatectomies (34%), and 30 total pancreatectomies (10%). Final pathology revealed malignancy in 203 cases (67.7%). When applying the scores, the proportion of patients malnourished or at risk of malnutrition ranged from 21.7% for SGA to 79.3% for NRS2002. After adjusting for selected confounders, only an MNA <17 was associated with severe postoperative complications (OR 8.39, 95%CI[1.95 – 32.31], p=0.01). MNA, SGA, and SNAQ predicted the length of stay (all p<0.01), while MNA and SGA also correlated with a higher probability of having a greater heterogeneity in the length of stay (p=0.04 and 0.002, respectively). DiscussionWe promote using MNA to detect malnourished patients at risk of severe postoperative complications and longer hospitalization after pancreatic surgery. SGA and SNAQ may also have value in predicting patients who will be hospitalized longer. More prospective studies will be needed to corroborate these findings.

Impact of Malnutrition on the Outcomes in Patients Admitted with Heart Failure.

Background: Heart failure, a major public health concern, significantly contributes to hospital admissions. This study evaluates the impact of malnutrition on both patient and hospital outcomes in heart failure admissions, with a specific focus on variations in outcomes based on the severity of malnutrition. Methods: Utilizing the National Inpatient Sample (NIS) database, this retrospective cohort study included adult patients admitted with a principal diagnosis of heart failure. Malnutrition was identified using the well-validated ICD 10 codes. We compared outcomes between patients with and without malnutrition, focusing on mortality, length of stay (LOS), hospital charges, cardiac arrest, and cardiogenic shock. Results: Out of 1,110,085 heart failure patients, 36,522 (3.29%) were malnourished. Malnourished patients exhibited significantly higher adjusted in-hospital mortality rates (aOR 3.32; 95% CI 3.03-3.64), longer LOS (mean increase of 4.67 days; p < 0.001), and higher hospital charges (mean increase of USD 77,416.9; p < 0.01). Increased rates of cardiac arrest (aOR 2.39; 95% CI 1.99-2.86; p < 0.001) and cardiogenic shock (aOR 3.74; 95% CI 3.40-4.12; p < 0.001) were also noted in malnourished patients. Severely malnourished patients faced worse outcomes compared to those with mild to moderate malnutrition. Conclusions: Heart failure patients with malnutrition experience higher mortality rates, longer hospital stays, increased hospitalization charges, and greater complication rates, including cardiac arrest and cardiogenic shock, compared to non-malnourished patients. Outcomes deteriorate with the increasing severity of malnutrition. Timely and individualized nutritional interventions may significantly improve outcomes for heart failure admissions.

Association between protein intake and functional capacity in critically ill patients: A retrospective cohort study.

Intensive care unit (ICU) protein benchmarks are based on mortality and morbidity; whether these targets also support functional recovery is unknown. We assessed whether different protein doses influenced patients' functional capacity, measured by the Chelsea Physical Assessment score (CPAx). Single-center retrospective cohort study on ICU survivors with length of stay ≥7 days admitted between October 2014 and September 2020. Eligible patients were divided according to protein intake (g/kg/day): low (<0.8), medium (0.8-1.19), high (1.2-1.5), and very high (>1.5). Protein dose effect on CPAx was assessed at ICU discharge with analysis of covariance adjusting for age, illness severity, hospital length of stay before ICU admission, time to start nutrition support, and mechanical ventilation duration. We also investigated effect modification by energy intake and nutrition status. Enrolled patients (n = 531) were similar for age, nutrition status, and illness severity across groups. CPAxs were nonlinearly associated with protein doses and similar among low, medium, and very high groups. The CPAx for the high group was statistically different (P = 0.014), indicating that the data of three groups could be pooled. Mean CPAx difference remained statistically significant after adjusting for confounding variables (3.9 ± 1.8, P = 0.029 in the four-group model, and 2.7 ± 0.9, P = 0.003 in the pooled two-group model). Energy intake was equivalent between groups and did not modify CPAx. The high group had superior CPAx in both well-nourished and malnourished patients, indicating nutrition status was not an effect modifier. Protein dose 1.2-1.5 g/kg/day was associated with superior functional capacity at ICU discharge compared with other doses. Neither energy intake nor nutrition status modified functional capacity across groups; therefore, the results appear to be influenced by 1.2-1.5 g/kg/day.

Nutritional Prehabilitation in Patients Undergoing Abdominal Surgery-A Narrative Review.

Malnutrition plays a crucial role as a risk factor in patients undergoing major abdominal surgery. To mitigate the risk of complications, nutritional prehabilitation has been recommended for malnourished patients and those at severe metabolic risk. Various approaches have been devised, ranging from traditional short-term conditioning lasting 7-14 days to longer periods integrated into a comprehensive multimodal prehabilitation program. However, a significant challenge is the considerable heterogeneity of nutritional interventions, leading to a lack of clear, synthesizable evidence for specific dietary recommendations. This narrative review aims to outline the concept of nutritional prehabilitation, offers practical recommendations for clinical implementation, and also highlights the barriers and facilitators involved.

The effect of Lactobacillus reuteri on pulmonary function test and growth of cystic fibrosis patients.

Cystic fibrosis (CF) patients frequently experience gut microbiota dysbiosis. Probiotic supplementation is a potential therapeutic approach to modify gut microbiota and improve CF management through the gut-lung axis. The aim of this study was to investigate the effect of Lactobacillus reuteri supplementation on pulmonary function test, respiratory symptoms and growth in CF patients. A randomized, placebo-controlled clinical trial was carried out on 40 children with CF aged from 6 to 20 years. Participants were designated to receive either L. reuteri or placebo daily for 4 months. Pulmonary function tests, weight, height and body mass index (BMI) z-scores were measured pre and post treatment. The median baseline BMI of the patients was 16.28 kg m-2. A significant change in the probiotic group's BMI z-score after the study period was observed (P = 0.034) but not for weight and height z-scores (P > 0.05). After treatment, Pseudomonas aeruginosa grew in sputum cultures of seven in the placebo and one patient in the intervention group (P = 0.03) while at baseline it grew in the sputum of four patients in each group. There was no significant difference in forced expiratory volume in the first second, forced expiratory flow at 25-75% or forced vital capacity change between the two groups after the treatment period (P > 0.05). Additionally, no significant differences were found in pulmonary exacerbations, hospitalization frequencies or COVID-19 infection between the two groups during the study (P > 0.05). The results suggest that L. reuteri supplementation may impact the growth of severely malnourished CF patients. Furthermore, it may be concluded that this strain might reduce P. aeruginosa in the sputum culture of CF patients. © 2024 Society of Chemical Industry.

Prevalence of malnutrition and impact on 30-day hospital readmission in adults receiving home care and ambulatory care: A descriptive cohort study.

Little is known about the prevalence of malnutrition among patients receiving home care (HC) and ambulatory care (AC) services. Further, the risk of hospital readmission in malnourished patients transitioning from hospital to HC or AC is also not well established. This study aims to address these two gaps. A descriptive cohort study of newly referred HC and AC patients between January and December 2019 was conducted. Nutrition status was assessed by clinicians using the Mini Nutritional Assessment-Short Form (MNA-SF). Prevalence of malnutrition and at risk of malnutrition (ARM) was calculated, and a log-binomial regression model was used to estimate the relative risk of hospital readmission within 30 days of discharge for those who were malnourished and referred from hospital. A total of 3704 MNA-SFs were returned, of which 2402 (65%) had complete data. The estimated prevalence of malnutrition and ARM among newly referred HC and AC patients was 21% (95% CI: 19%-22%) and 55% (95% CI: 53%-57%), respectively. The estimated risk of hospital readmission for malnourished patients was 2.7 times higher (95% CI: 1.9%-3.9%) and for ARM patients was 1.9 times higher (95% CI: 1.4%-2.8%) than that of patients with normal nutrition status. The prevalence of malnutrition and ARM among HC and AC patients is high. Malnutrition and ARM are correlated with an increased risk of hospital readmission 30 days posthospital discharge.

Secondary carnitine deficiency during refeeding in severely malnourished patients with eating disorders: a retrospective cohort study

BackgroundSecondary carnitine deficiency in patients with anorexia nervosa has been rarely reported. This study aimed to investigate the occurrence of carnitine deficiency in severely malnourished patients with eating disorders during refeeding and assess its potential adverse effects on treatment outcomes.MethodIn a cohort study of 56 female inpatients with eating disorders at a single hospital from March 2010 to December 2020, we measured plasma free carnitine (FC) levels and compared to those of a healthy control group (n = 35). The patients were categorized into three groups based on FC levels: FC deficiency (FC< 20 µmol/L), FC pre-deficiency (20 µmol/L ≤ FC< 36 µmol/L), and FC normal (36 µmol/L ≤ FC).ResultsUpon admission, the patients had a median age of 26 years (interquartile range [IQR]: 21–35) and a median body mass index (BMI) of 13.8 kg/m2 (IQR: 12.8–14.8). Carnitine deficiency or pre-deficiency was identified in 57% of the patients. Hypocarnitinemia was associated with a decline in hemoglobin levels during refeeding (odds ratio [OR]: 0.445; 95% confidence interval [CI]: 0.214–0.926, p = 0.03), BMI at admission (OR: 0.478; 95% CI: 0.217–0.874, p = 0.014), and moderate or greater hepatic impairment at admission (OR: 6.385; 95% CI: 1.170–40.833, p = 0.032).ConclusionsHypocarnitinemia, particularly in cases of severe undernutrition (BMI< 13 kg/m2 at admission) was observed in severely malnourished patients with eating disorders during refeeding, a critical metabolic transition phase. Moderate or severe hepatic impairment at admission was considered a potential indicator of hypocarnitinemia. Although hypocarnitinemia was not associated with any apparent adverse events other than anemia during refeeding, the possibility that carnitine deficiency may be a risk factor for more serious complications during sudden increases in energy requirements associated with changes in physical status cannot be denied. Further research on the clinical significance of hypocarnitinemia in severely malnourished patients with eating disorders is warranted.

Effect of Enteral Protein Supplements on Malnourished Hemodialysis Patients

Abstract Background Protein-calorie malnutrition is common in chronic hemodialysis patients and correlates with morbidity and mortality. There are limited trials evaluating the efficacy of oral nutritional supplementation in malnourished CHD patients. Aim of the Work To evaluate the effect of 6-month-long intradialytic amino acids (AA) supplementation on selected nutritional variables in malnourished hemodialysis (HD) patients. Patients and Methods This was prospective, intervention-controlled study, was conducted in haemodialysis unit Ahmed Maher Teaching Hospital, and other authorized hospitals nephrology clinics on 60 patients divided into 2 groups: (Group A); received oral formula, (Group B); the control group on their normal diet. Results There were high statistically difference between the studied groups on nutritional markers. Conclusion Malnutrition is common in incident and prevalent HD patients however enteral protein supplements can also help on increasing nutritional markers.

610 The Effectiveness of Adipose Tissue Derived Mesenchymal Stem Cells Mixed with Platelet Rich Plasma in the Healing of Inflammatory Bowel Anastomoses: A Pre-Clinical Study in Rats

Abstract Aim Anastomotic leak is a detrimental complication following bowel surgery leading to prolonged hospital stay, increased healthcare costs and significant increase in morbidity and mortality. The aim of this study is to investigate the effect of adipose derived mesenchymal stem cells (MSCs) mixed with platelet rich plasma (PRP) in the healing of bowel anastomoses, in an inflammatory environment . Method Thirty-five male Wistar rats were divided into five groups of seven animals: normal controls, colitis controls, PRP, MSCs, and PRP + MSCs. All groups underwent laparotomy, segmental colectomy and anastomosis in situ. Colitis was previously established by transrectal administration of 2,4,6-trinitrobenzene sulfonic acid (TNBS) except for the normal controls. Post-mortem histopathological, tissue hydroxyproline and anastomotic bursting pressure (ABP) assessments were performed. Results Tissue hydroxyproline and ABP were significantly increased in the group of PRP+MSCs compared to colitis controls (p=0.0151 and p=0.0104, respectively). Inflammatory cell infiltration was lower and fibroblast activity higher in PRP + MSCs group, but not statistically significant. Neoangiogenesis (p=0.0073) and anastomotic area epithelialization (p=0.0182) were significantly higher in PRP + MSCs group compared to colitis controls. Conclusions The synergic effect of the PRP and MSCs is shown to significantly improve healing in bowel anastomoses even on a background of inflammation. These results give hope for primary anastomosis and potentially avoiding stoma and its complications, especially in immunocompromised or malnourished patients undergoing bowel resection. Clinical studies should follow in order to support the clinical application of PRP and MSCs combination in gastrointestinal anastomoses.

Malnutrition among Egyptian hemodialysis patients: prevalence and risk factors

Background Malnutrition commonly affects hemodialysis (HD) patients. Malnourished HD patients have increased morbidity and mortality. We aimed to assess the prevalence and risk factors of malnutrition among Egyptian hemodialysis patients. Material and methods This is a cross-sectional study carried out on ESRD patients with regular HD. All participants were subjected to detailed history taking and complete physical examination. Assessment of nutritional status was done using subjective global assessment (SGA). Anthropometric measures included mid-arm circumference (MAC), triceps skin fold (TSF), and body mass index (BMI) assessment. Results One hundred thirty patients with a mean age of 55.2 ± 12.6 years, completed the study. The mean duration of HD was 4.51 ± 3.68 years. The mean SGA was 12.1 ± 3.9. Malnutrition was present in 34 (26.2%) patients [mild to moderate (23.8%), severe (2.4%)]. Patients had a mean BMI of 25.69 ± 4.5 kg/m2, a mean MAC of 25.9 ± 4.9 cm, and a mean TSF of 18.1 ± 8.9 mm. There was a significant negative correlation between malnutrition and mid arm circumference and serum Na with P value of 0.003 and 0.012, respectively. Patients with malnutrition had a significantly longer duration on HD (P=0.004), lower Kt/V (P=0.040), lower serum albumin (P=0.007), lower BMI (P=0.002), less MAC (P=0.002), less TSF (P=0.002). Conclusions Malnutrition is common in HD patients with a significant inverse correlation with mid arm circumference and serum Na. Malnourished patients had a longer duration on HD, lowered serum albumin, BMI, dialysis adequacy and anthropometric measures.

Nutritional support in pancreatic cancer patients and its effect on nutritional status: an observational regional HPB network study investigating current practice

PurposePreoperative malnutrition is associated with poor postoperative outcomes in patients with pancreatic cancer. This study evaluated the effectiveness of current practice in nutritional support for patients with pancreatic cancer.MethodsObservational multicenter HPB network study conducted at the Isala Clinics Zwolle, Medical Spectrum Twente, Medical Center Leeuwarden, and University Medical Center Groningen between October 2021 and May 2023. Patients with a suspected pancreatic malignancy scheduled for surgery were screened for malnutrition using the Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire and referred to a dedicated dietician for nutritional support comprising pancreatic enzyme replacement therapy, dietary advice, and nutritional supplements to achieve adequate caloric and protein intake. At baseline, 1 day preoperatively, and 3 months postoperatively, the nutritional status and muscle thickness were evaluated.ResultsThe study included 30 patients, of whom 12 (40%) classified as malnourished (PG-SGA ≥ 4) at baseline. Compared to well-nourished patients, malnourished patients were younger, were predominantly female, and had a higher body mass index, despite having lost more body weight in the past 6 months. All malnourished patients and 78% of the well-nourished patients received nutritional support. Consequently, a preoperative increase in caloric and protein intake and body weight were observed. Postoperatively, despite a further increase in caloric intake, a considerable decrease in protein intake, body weight, and muscle thickness was observed.ConclusionMalnutrition is prevalent in patients undergoing pancreatic surgery. Nutritional support by a dedicated dietician is effective in enhancing patients’ preoperative nutritional status. However, postoperative monitoring of adequate nutritional intake in patients could be improved.

Albumin-dNLR score could be an etiological criterion to determine inflammation burden for GLIM in medical inpatients over 70 years old: A multicenter retrospective study

AimTo validate the role of the albumin-derived neutrophil-to-lymphocyte (ALB-dNLR) score in diagnosing malnutrition in medical inpatients over 70 years old. MethodsThis is a retrospective cross-sectional study involving 7 departments from 14 Chinese hospitals. The ALB-dNLR score was calculated, and outcomes between groups with positive and negative ALB-dNLR scores were compared after propensity score matching (PSM). Afterwards, the outcomes were compared between the groups receiving nutrition support and those not receiving support among malnourished patients diagnosed using the Global Leadership Initiative Malnutrition (GLIM) criteria after PSM. ResultsOut of 10,184 cases, 6165 were eligible. 2200 cases were in the positive ALB-dNLR score group. After PSM, 1458 pairs were analyzed, showing lower in-hospital mortality (0.8 % vs. 2.1 %, p = 0.005) and a lower nosocomial infection rate (5.9 % vs. 11.0 %, p < 0.001) in the negative ALB-dNLR score group. In malnourished patients, 259 pairs were analyzed after PSM. It showed better outcomes in mortality (0.8 % vs. 3.5 %, p = 0.033), nosocomial infection rate (5.4 % vs. 15.4 %, p < 0.001), length of stay (LOS) (13.8 ± 10.3 vs. 18.4 ± 14.1, p < 0.001), and total hospital cost (3315.3 ± 2946.4 vs. 4795.3 ± 4198.2, p < 0.001) in the support group. In malnourished patients with ALB-dNLR score as the sole etiological criterion, 94 pairs were calculated. It showed better outcomes in mortality (0.0 % vs. 6.4 %, p = 0.029), nosocomial infection rate (7.4 % vs. 18.1 %, p = 0.029), LOS (13.7 ± 8.3 vs. 19.8 ± 15.2, p = 0.001), and total hospital cost (3379.3 ± 2955.6 vs. 4471.2 ± 4782.4, p = 0.029) in the support group. ConclusionsThe ALB-dNLR score was validated to predict in-hospital mortality in medical inpatients over 70 years old. Malnutrition patients diagnosed by the GLIM criteria and using the ALB-dNLR score might benefit from nutrition support.
