Medical Comorbidities, Nutritional Markers, and Cardiovascular Risk Markers in Youth With ARFID.

OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID) is common among populations with nutrition-related medical conditions. Less is known about the medical comorbidity/complication frequencies in youth with ARFID. We evaluated the medical comorbidities and metabolic/nutritional markers among female and male youth with full/subthreshold ARFID across the weight spectrum compared with healthy controls (HC). METHOD: In youth with full/subthreshold ARFID (n = 100; 49% female) and HC (n = 58; 78% female), we assessed self-reported medical comorbidities via clinician interview and explored abnormalities in metabolic (lipid panel and high-sensitive C-reactive protein [hs-CRP]) and nutritional (25[OH] vitamin D, vitamin B12, and folate) markers. RESULTS: Youth with ARFID, compared with HC, were over 10 times as likely to have self-reported gastrointestinal conditions (37% vs. 3%; OR = 21.2; 95% CI = 6.2-112.1) and over two times as likely to have self-reported immune-mediated conditions (42% vs. 24%; OR = 2.3; 95% CI = 1.1-4.9). ARFID, compared with HC, had a four to five times higher frequency of elevated triglycerides (28% vs. 12%; OR = 4.0; 95% CI = 1.7-10.5) and hs-CRP (17% vs. 4%; OR = 5.0; 95% CI = 1.4-27.0) levels. DISCUSSION: Self-reported gastrointestinal and certain immune comorbidities were common in ARFID, suggestive of possible bidirectional risk/maintenance factors. Elevated cardiovascular risk markers in ARFID may be a consequence of limited dietary variety marked by high carbohydrate and sugar intake.

Investigating the impact of nutritional insufficiency on parahippocampal neurons in domestic chickens, Gallus gallus domesticus.

Over time, scientists have been fascinated by the complex connections among nutrition, brain development, and behavior. It's been well understood that the brain's peak performance relies on having the right nutrients available. Thus, nutritional insufficiency, where an organism lacks vital nutrients crucial for optimal growth and function, can upset the body's balance, potentially triggering stress responses. However, our grasp of how the brain reacts to insufficient nutrition, particularly in avian species like domestic chickens, has shown inconsistencies in our understanding. Domestic chickens have frequently served as subjects for studying memory and learning, primarily focusing on the hippocampus-a region highly responsive to environmental changes. Yet, another critical brain region, the parahippocampal region, integral to memory and spatial cognition, had received relatively little attention concerning the consequences of inadequate nutrition and hydration. To address this knowledge gap, our study sought to investigate the impact of stress induced by nutritional insufficiency on the neuronal cells within the region parahippocampalis in two distinct age groups of domestic chickens, Gallus gallus domesticus: fifteen and thirty days old. We employed the Golgi-Cox-Impregnation technique to explore whether the structural characteristics of neuronal cells, specifically the dendritic spines, underwent changes under transient stressful conditions during these crucial developmental stages. The results were intriguing. Stress evidently induced observable alterations in the dendritic spines of the parahippocampal neuronal cells, with the extent of these changes being age-dependent. In fifteen-day-old chickens, stress prompted substantial modifications in the dendritic spines of parahippocampal multipolar and pyramidal neurons. In contrast, among thirty-day-old chickens, the response to stress was less comprehensive, with only specific parahippocampal multipolar neurons displaying such alterations. These findings underscored the influential role of stress in reshaping the structure of parahippocampal neurons and emphasized the importance of considering age when studying the impact of stress on the brain. Through this research, we aim to enhance our understanding of the intricate interplay between stress, brain structure, and the critical role of adequate nutrition, especially during pivotal developmental stages. Our future research objectives include a deeper investigation into the intracellular events including cellular and molecular mechanisms precipitating these changes and determining whether these alterations have downstream effects on crucial brain functions like learning and memory.

[Complications of percutaneous endoscopic gastrostomy in intensive care patients with dysphagia associated with neurological disorders]. / Oslozhneniya chreskozhnoi endoskopicheskoi gastrostomii u reanimatsionnykh bol'nykh s sindromom disfagii tsentral'nogo geneza.

OBJECTIVE: To develop an effective method for percutaneous endoscopic gastrostomy using gastropexy technology. MATERIAL AND METHODS: We retrospectively analyzed 260 ICU patients with dysphagia associated with neurological disorders between 2010 and 2020. All patients were divided into two groups: the main group (n=50) - percutaneous endoscopic gastrostomy with gastropexy, control group (n=210) - surgery without fixing the anterior wall of the stomach to the abdominal wall. RESULTS. G: Astropexy significantly reduced the incidence of postoperative complications (p=0.045) and severe complications (grade IIIa and higher) (χ2=3.701, p=0.055). Early postoperative complications occurred in 20 (7.7%) patients. Surgery and subsequent treatment were associated with normalization of leukocyte count (p=0.041), C-reactive protein (p=0.024) and serum albumin (p=0.0012). Mortality was similar in both groups. Overall 30-day mortality rate in both groups was 20.8% that was associated with clinical severity of patients. Percutaneous endoscopic gastrostomy was not the direct cause of death in any case. However, complications of endoscopic gastrostomy aggravated the underlying disease in 2.9% of cases. CONCLUSION: Percutaneous endoscopic gastrostomy with gastropexy reduces the incidence of postoperative complications.

Electrocardiographic QTc as a Surrogate Measure of Cardiac Risk in Children, Adolescents, and Young Adults With Eating Disorders.

The study goal was to investigate electrocardiographic findings, including corrected QT interval (QTc), in patients aged 8 to 23 with eating disorders (EDs) at presentation, compared with an age-and sex-matched control population. We retrospectively reviewed 200 ED patients, and 200 controls. Blinded electrocardiograms (ECGs) were interpreted by an expert reader, and QT intervals corrected using the Bazett formula. Eating disorder patients were 89.5% female, with mean age 16.4 years and median percent median body mass index (BMI)-for-age (%mBMI)a of 91.1%. In ED patients, QTc was significantly shorter than controls (399.6 vs 415.0msec, P < .001). After adjusting for height, %mBMI, sex, magnesium level, and bradycardia, mean QTc duration in patients with anorexia nervosa-restricting subtype (AN-R) was significantly shorter than other ED patients (P = .010). Higher %mBMI was associated with shorter QTc duration (P = .041) after adjusting for height, magnesium, bradycardia, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis. Within the ED group, no significant association was identified between QTc and medications, electrolytes, or inpatient status.

[The role of nutrition status correction in the rehabilitation of cancer patients]. / Rol' korrektsii nutritivnogo statusa v reabilitatsii onkologicheskikh patsientov.

Metabolic changes due to the progression of malignant neoplasms and the negative consequences of aggressive methods of its treatment lead to a decrease in food intake in patients, which contributes to the development of anorexia-cachexia syndrome in cancer patients due to complex interactions between pro-inflammatory cytokines and host metabolism. Within the framework of this article, the author analyzes the possibility of the influence of nutritional status in cancer patients. The analysis of the results of the study of a group of cancer patients with various nutritional statuses was carried out. It is concluded that the control and correction of nutritional status should become an integral part of the assessment of the quality of life and meet the needs and expectations of the patient.

[Characteristics of the metabolic status of children of the first year of life with protein-energy deficiency depending on the gestational age at birth.] / Характеристика метаболического статуса детей первого года жизни с белково-энергетической недостаточностью в зависимости от гестационного возраста при рождении.

Comparative analysis of energy-plastic exchange indicators in mature and premature children of the first year of life in the development of protein-energy malnutrition (PEM) was carried out. Unidirectional changes are revealed, including an increase in creatinine, lactate and creatine phosphokinase activity levels, suggesting a n increasing muscle mass deficit against the background of glucose anaerobic oxidation activation. In preterm infants, glucose and triacylglicerine levels decrease, which reflects uncompensated insufficiency of energy substrates and, accordingly, ATP level. Multidirectional deviations in metabolism are pyruvate and ATP content: increase in full-term infants and decrease in preterm infants, that should be taken into account when monitoring condition of children with PEM. A significant decrease of pyruvic acid in preterm infants against the background of the levels of total protein, albumin, hemoglobin, and transferrin, not exceeding reference values, can obviously testify to the active use of this integral metabolite to maintain the fund of substituted amino acids. Development of this pathology in both mature and premature infants creates a pre-morbid background for iron deficiency anemia-diagnostic panel, which should be supplemented by calculation of transferrin saturation coefficient. Regardless of gestational age in childbirth during the formation of PEM, the lipid spectrum is rearranged according to atherogenic type: at normal values of total cholesterol, there is a significant increase in low and very low density lipoproteins with an increase in the atherogenicity coefficient. This singles out children with the pathology in question as a risk group for the development of the atherosclerotic process later, which justifies the recommendation to control the lipid profile in children of the first year of life.

[Resected bowel syndrome: clinical course and treatment options].

The current concepts of the short bowel syndrome and malabsorption after intestinal surgery are generally accepted, but do not fully reflect the patients condition, making it difficult to diagnose and treat it. AIM: The purpose of the study is to analyze the clinical course of the patients after bowel resection, to create a classification based on the variants identified to allow for a differentiated treatment and to introduce the concept of the resected bowel syndrome. MATERIALS AND METHODS: We observed 239 patients (96 men and 143 women) aged 18 to 80 who underwent intestinal resection for 1 month to 16 years (from 2002 to 2018). The 1st group included 96 patients with small bowel resection (40 men and 56 women). The 2nd group included 39 men and 58 women with small bowel resection, including the resection of the ileocecal valve and the right-hand side of the colon (n=97). The 3rd group included 17 men and 29 women with the resection of the right-hand side of the colon or colectomy (n=46). The survey included the NRS-2002 (Nutritional Risk Screening 2002) screening test to identify nutritional risk, a clinical assessment of the symptoms that occurred after the surgery, instrumental methods (esophagogastroduodenoscopy, colonoscopy with biopsy, ultrasound of the abdominal cavity organs and the kidneys, a plain radiography of the abdominal cavity organs, an X-ray examination of the small intestine and the intestinal passage), serum citrulline and short-chain fatty acids in faeces. RESULTS: Based on the analysis of the clinical symptoms and the nutritional status of the patients, a new concept is proposed the resected bowel syndrome with two variants of its progression: either with or without the development of nutritional insufficiency of three types: the dehydration type, the protein-energy insufficiency type and a mixed type. Type 1 requires the use of antimicrobials with the control of SCFA concentrations in faeces. Type 2 requires the introduction of an optimal amount of easily digestible protein to correct protein-energy deficit. The 3rd (most severe) mixed type requires prescription of a parenteral nutrition component with the control of citrulline concentration in the blood serum. CONCLUSION: The proposed concept the resected bowel syndrome makes it possible to improve its diagnosis, take into account the variants of its progression and allow for a differentiated treatment.

A Diet High in Processed Foods, Total Carbohydrates and Added Sugars, and Low in Vegetables and Protein Is Characteristic of Youth with Avoidant/Restrictive Food Intake Disorder.

Avoidant/restrictive food intake disorder (ARFID) is characterized in part by limited dietary variety, but dietary characteristics of this disorder have not yet been systematically studied. Our objective was to examine dietary intake defined by diet variety, macronutrient intake, and micronutrient intake in children and adolescents with full or subthreshold ARFID in comparison to healthy controls. We collected and analyzed four-day food record data for 52 participants with full or subthreshold ARFID, and 52 healthy controls, aged 9-22 years. We examined frequency of commonly reported foods by logistic regression and intake by food groups, macronutrients, and micronutrients between groups with repeated-measures ANOVA. Participants with full or subthreshold ARFID did not report any fruit or vegetable category in their top five most commonly reported food categories, whereas these food groups occupied three of the top five groups for healthy controls. Vegetable and protein intake were significantly lower in full or subthreshold ARFID compared to healthy controls. Intakes of added sugars and total carbohydrates were significantly higher in full or subthreshold ARFID compared to healthy controls. Individuals with full or subthreshold ARFID had lower intake of vitamins K and B12, consistent with limited vegetable and protein intake compared to healthy controls. Our results support the need for diet diversification as part of therapeutic interventions for ARFID to reduce risk for nutrient insufficiencies and related complications.

[The Insufficiency Type of Metabolic Balance and Nutritional Status in Patient With Heart Failure].

A lot of data has been accumulated at present on the metabolic and nutritional insufficiency in patients with chronic heart failure (CHF). Researchers have noted an actuality of the study of nutritional and metabolic insufficiency in CHF patients as independent factors affecting the course of CHF and because of its relationship with triggers of inflammation, sympathetic-adrenal system, and markers of functional state of the cardiovascular system (CVS). In some works attention has been given to relationship of nutritional and metabolic insufficiency with autonomic regulation of cardiac rhythm. Attempts have been made to systematize obtained data, create contemporary pathophysiological portrait of CHF development and highlight prevailing mechanisms of progression of the disease. This review summarizes accumulated data on nutritional insufficiency in patients with CHF and systematizes metabolic changes according to types of metabolism and CHF functional class. We have also made an attempt of creating figurative representation of pathophysiological mechanism of development of nutritional insufficiency in CHF. We have emphasized the problem of inadequate knowledge on contribution of inflammatory markers in development of nutritional insufficiency especially in patients with I-II functional classes of CHF. We also present suggestions concerning strategy of studying nutritional insufficiency in CHF, its classification according to CHF functional class, stratification of risk factors of its development, and the methods of its prevention and correction.

Medical stabilization of adolescents with nutritional insufficiency: a clinical care path.

PURPOSE: Nutritional insufficiency (NI) is a potential consequence of restrictive eating disorders. NI patients often require hospitalization for refeeding to restore medical stability and prevent complications such as refeeding syndrome. Limited information is available on the optimal approach to refeeding. In this study, we describe an inpatient NI care path and compare treatment outcomes at an academic medical center and a community hospital. METHODS: A retrospective chart review was conducted on inpatients treated using a standardized NI care path at either the academic site, from August 2012 to July 2013 (n = 51), or the community site, from August 2013 to July 2014 (n = 39). Demographic information, eating disorder history, and treatment variables were recorded for each patient. Data were compared using the Kruskal-Wallis test and Fisher's exact test. RESULTS: Patients admitted to the community site had shorter hospital stays than patients admitted to the academic site (IQR 2-4 vs. 2-7 days, p = 0.03). All patients were discharged in <14 days with a median stay of 3 days. The median initial calorie prescription was 2200 calories for both groups. No clinical cases of refeeding syndrome occurred, with only one patient developing hypophosphatemia during refeeding. CONCLUSIONS: A standardized care path with a higher-calorie intervention allows for short-term hospitalization of NI patients without increasing the risk of refeeding syndrome, regardless of treatment site. This study demonstrates the efficiency and safety of treating NI patients on a regular medical floor at a community hospital.

Long-term effects of gastrectomy in patients with spirometry-defined COPD and patients at risk of COPD: a case-control study.

OBJECTIVE: Comorbidities are characteristic of COPD. However, little is known about the secondary manifestations of COPD in the gastrointestinal tract. Therefore, we aimed to explore the long-term effects of gastrectomy in patients with spirometry-defined COPD or those at risk of COPD. PARTICIPANTS: Subjects included 87 patients either with COPD or at risk of COPD (symptomatic) who underwent gastrectomy between December 2003 and October 2013 (group A), and 174 patients either with COPD or at risk of COPD, matched by age (±5 years), sex, and forced expiratory volume in 1 second (FEV1) as percentage of predicted (FEV1% predicted) (±5%) (group B). METHODS: All patients underwent routine blood chemistry and pulmonary function tests, arterial blood gas analysis, 6-minute walk test (6MWT), high-resolution chest computed tomography scans, and nutritional assessments. RESULTS: The mean duration postgastrectomy was 18.3±15.4 years. The mean FEV1 and FEV1% predicted were 2.07±0.76 L and 74.6±24.5%, respectively. Univariate analysis indicated that group A patients had significantly lower body mass index, fat-free mass index, and serum hemoglobin and albumin concentration (all P=0.00), and walked a significantly shorter distance in the 6MWT (P<0.05). Multivariate linear regression analysis for the distance in the 6MWT indicated that increased residual volume (RV) to total lung capacity (TLC) as percentage of predicted (%RV/TLC) alone was an independent and significant predictor of reduced distances in the 6MWT. CONCLUSION: We concluded that nutritional insufficiency in patients with COPD (or those at risk of COPD) who previously underwent gastrectomy might lead to hyperinflation and consequently, decreased exercise capacity.
