Prevalence of the use of oral nutritional supplements among acute inpatients at risk of malnutrition and associated patient characteristics.

AIM: To provide a snapshot of the current use of oral nutritional supplements, its association with inpatient characteristics, and with a focus on the role of nursing monitoring of food intake and implementing nutritional interventions for patients with low intake. DESIGN: Retrospective cohort study. METHODS: The study collected data from a hospital database regarding oral nutritional supplement initiation and variables of patients hospitalised in internal medicine departments, who did not receive enteral or parenteral nutrition. RESULTS: Of the 5155 admissions, 1087 fulfilled the inclusion criteria (47% female; mean age, 72.4 ± 14.6 years; mean length of stay, 14.6 ± 11.4 days). Sufficient food intake reporting was noted in 74.6% of the patients; of these 17% had decreased intake. Oral nutritional supplements and non-oral nutritional supplements groups did not differ in terms of sex, age, length of stay, Charlson Comorbidity Index, proportion of nursing reports, and absence of intake monitoring. Oral nutritional supplements were initiated in 31.9% of patients with a Malnutrition Universal Screening Tool score ≥2 and in 34.6% with decreased food intake. On multivariable analysis, hypoalbuminemia (adjusted odds ratio, 3.70), decreased food intake (adjusted odds ratio, 3.38), Malnutrition Universal Screening Tool score ≥2 (adjusted odds ratio, 2.10), and age <70 years (adjusted odds ratio, 1.56) were significantly associated with oral nutritional supplements use. CONCLUSION: The prevalence of oral nutritional intervention was suboptimal in patients at risk of malnutrition during acute hospitalisation, although decreased food intake and Malnutrition Universal Screening Tool score ≥2 independently increased the probability of oral nutritional supplements initiation. RELEVANCE IN CLINICAL PRACTICE: Understanding the clinical practice and nursing impact of care management in relation to nutritional intervention can assist in reviewing and improving patient care. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE IMPACT (ADDRESSING): This study informs clinical management and influences nursing practice standards related to assessing, monitoring, and managing malnutrition risk. IMPACT: The study impacts the quality of care for patients at risk of malnutrition. REPORTING METHOD: We adhered to the STROBE Checklist for cohort studies. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Practical guideline on obesity care in patients with gastrointestinal and liver diseases - Joint ESPEN/UEG guideline.

BACKGROUND: Patients with chronic gastrointestinal disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean gastrointestinal patients. The present guideline addresses this question according to current knowledge and evidence. OBJECTIVE: The present practical guideline is intended for clinicians and practitioners in general medicine, gastroenterology, surgery and other obesity management, including dietitians and focuses on obesity care in patients with chronic gastrointestinal diseases. METHODS: The present practical guideline is the shortened version of a previously published scientific guideline developed according to the standard operating procedure for ESPEN guidelines. The content has been re-structured and transformed into flow-charts that allow a quick navigation through the text. RESULTS: In 100 recommendations (3× A, 33× B, 24 × 0, 40× GPP, all with a consensus grade of 90% or more) care of gastrointestinal patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially metabolic associated liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. CONCLUSION: The present practical guideline offers in a condensed way evidence-based advice how to care for patients with chronic gastrointestinal diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Evaluation of prevalence of food intake monitoring during acute hospitalization and its association with malnutrition screening scores of inpatients who were not considered for enteral or parenteral nutrition.

OBJECTIVES: Malnutrition risk can be recognized by nurses using screening tools and food intake monitoring. We measured the prevalence of food intake reporting and its association with malnutrition screening scores or other patient characteristics. METHODS: This retrospective cohort study collected hospital database information regarding patients aged ≥18 y who were hospitalized for ≥ 7 consecutive days and were orally fed or had medical records that no tube feeding or parenteral nutrition had been administered. Data were collected and statistically analyzed focusing on food intake reporting, Malnutrition Universal Screening Tool (MUST) scores, oral nutritional intervention, and other secondary characteristics. RESULTS: Out of 5155 patients admitted to two internal medicine departments over 1 y (July 1, 2018, through August 31, 2019), 1087 fulfilled the inclusion criteria with a mean age of 72.4 ± 14.6 y; of these, 74.6% had sufficient food intake reports. No food intake was reported for one-third of patients with MUST scores ≥ 2. There were no differences between the groups of patients with and without reported food intake with regard to MUST scores, sex, mean albumin level, comorbidity, length of stay, all-cause in-hospital mortality, hospital-acquired pressure injury, or the rate of oral nutritional intervention. MUST scores ≥ 2 were not significantly associated with intake reporting. Increased probability of having food intake reported was found in patients ages ≥70 y (adjusted odds ratio = 1.36; P = 0.036 [95% CI, 1.02-1.82]) and those who had Norton scores ≤ 13 (adjusted odds ratio = 1.60; P = 0.013 [95% CI, 1.10-2.31]). However, the model had a weak predictive efficacy (area under the curve = 0.577; P < 0.0001 [95% CI, 0.538-0.616]). CONCLUSIONS: More adherence to food intake monitoring guidelines is needed.

The Association Between Low Body-Mass Index and Serious Post-endoscopic Adverse Events.

BACKGROUND: Low body mass index (LBMI) was associated with longer colonoscopy procedure time and procedural failure, and commonly considered to be a risk factor for post-endoscopic adverse events, but evidence is lacking. AIM: We aimed to assess the association between serious adverse events (SAE) and LBMI. METHODS: A single center retrospective cohort of patients with LBMI (BMI ≤ 18.5) undergoing an endoscopic procedure was matched (1:2 ratio) to a comparator group (19 ≤ BMI ≤ 30). Matching was performed according to age, gender, inflammatory bowel disease or malignancy diagnoses, previous abdomino-pelvic surgery, anticoagulation therapy and type of endoscopic procedure. The primary outcome was SAE, defined as bleeding, perforation, aspiration or infection, following the procedure. The attribution between each SAE and the endoscopic procedure was determined. Secondary outcomes included each complication alone and endoscopy-attributed SAEs. Univariate and multivariate analyses were applied. RESULTS: 1986 patients were included (662 in the LBMI group). Baseline characteristics were mostly similar between the groups. The primary outcome occurred in 31/662 (4.7%) patients in the LBMI group and in 41/1324 (3.1%) patients in the comparator group (p = 0.098). Among the secondary outcomes, infections (2.1% vs. 0.8%, p = 0.016) occurred more frequently in the LBMI group. Multivariate analysis revealed an association between SAE and LBMI (OR 1.76, 95% CI 1.07-2.87), male gender, diagnosis of malignancy, high-risk endoscopic procedure, age > 40 years, and ambulatory setting. CONCLUSION: Low BMI was associated with higher post-endoscopic serious adverse events. Special attention is required when performing endoscopy in this fragile patient population.

Absence of oral nutritional support in low food intake inpatients is associated with an increased risk of hospital-acquired pressure injury.

BACKGROUND & AIMS: Hospital-acquired pressure injury (HAPI) incidence is a common burden in hospitals. Decreased food intake leading to malnutrition compromises body tissues involved in pressure injury occurrence. However, most tools for predicting pressure injuries do not include daily food intake monitoring nor consider further nutritional interventions. This study aimed to investigate clinical practices for food intake monitoring and its association with predicting HAPI risk, together with Norton Scale use, and whether the initiation or absence of oral nutritional supplements (ONS), separately from other nutritional interventions, was associated with HAPI incidence in low food intake inpatients, who consumed less than 50% of requirements. METHODS: This observational cohort study covered a one-year period (08/2018-07/2019). Demographic and clinical data were extracted from computerized files of patients hospitalized ≥7 days, aged ≥60 years, and who ate orally. Patients receiving enteral or parenteral nutrition were excluded. Differences were studied between groups without and with HAPI grade ≥2. Subgroups divided by Norton Scale and intake, Norton Scale and albumin levels, food intake and initiation (or not) of any nutritional intervention versus ONS only, were examined for the consistency of association with HAPI. RESULTS: Of the 5155 admissions during the study period, 895 patients fulfilled the inclusion criteria: 48% female, mean age 77.6 ± 9.1 years, 11% with MUST score ≥2. Nutritional intake was reported in 76% of patients, of them 22% had low food intake, and 9% of the study group developed HAPI grade ≥2. Regarding HAPI incidence, no differences were found between groups divided by MUST scores. Independent risk factors significantly associated with HAPI were Norton <14, albumin levels <3 g/dl, and low food intake. Not providing ONS in low food intake patients had an adjusted 3.49-fold (95%CI 1.57-7.75) increase in HAPI risk (6-fold for non-adjusted relative risk). CONCLUSION: Failure to initiate ONS as part of nutritional support in low food intake patients is associated with high HAPI risk in these patients. Consequently, monitoring of daily food intake for identifying low intake patients should be integrated into routinely used tools such as the Norton Scale, and adherence to nutritional protocols should be addressed.

European guideline on obesity care in patients with gastrointestinal and liver diseases - Joint European Society for Clinical Nutrition and Metabolism / United European Gastroenterology guideline.

BACKGROUND: Patients with chronic gastrointestinal (GI) disease such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, gastroesophageal reflux disease (GERD), pancreatitis, and chronic liver disease (CLD) often suffer from obesity because of coincidence (IBD, IBS, celiac disease) or related pathophysiology (GERD, pancreatitis and CLD). It is unclear if such patients need a particular diagnostic and treatment that differs from the needs of lean GI patients. The present guideline addresses this question according to current knowledge and evidence. OBJECTIVE: The objective of the guideline is to give advice to all professionals working in the field of gastroenterology care including physicians, surgeons, dietitians and others how to handle patients with GI disease and obesity. METHODS: The present guideline was developed according to the standard operating procedure for European Society for Clinical Nutrition and Metabolism guidelines, following the Scottish Intercollegiate Guidelines Network grading system (A, B, 0, and good practice point [GPP]). The procedure included an online voting (Delphi) and a final consensus conference. RESULTS: In 100 recommendations (3x A, 33x B, 24x 0, 40x GPP, all with a consensus grade of 90% or more) care of GI patients with obesity - including sarcopenic obesity - is addressed in a multidisciplinary way. A particular emphasis is on CLD, especially fatty liver disease, since such diseases are closely related to obesity, whereas liver cirrhosis is rather associated with sarcopenic obesity. A special chapter is dedicated to obesity care in patients undergoing bariatric surgery. The guideline focuses on adults, not on children, for whom data are scarce. Whether some of the recommendations apply to children must be left to the judgment of the experienced pediatrician. CONCLUSION: The present guideline offers for the first time evidence-based advice how to care for patients with chronic GI diseases and concomitant obesity, an increasingly frequent constellation in clinical practice.

Monogenic Inflammatory Bowel Disease: It's Never Too Late to Make a Diagnosis.

Background: More than 50 different monogenic disorders have been identified as directly causing inflammatory bowel diseases, typically manifesting in the first years of life. We present the clinical course and immunological work-up of an adult patient who presented in adolescent years with an atypical gastrointestinal phenotype and was diagnosed more than two decades later with a monogenic disorder with important therapeutic implications. Methods: Whole exome sequencing was performed in a 37-years-old patient with a history of diarrhea since adolescence. Sanger sequencing was used to validate the suspected variant. Mass cytometry (CyTOF) and flow cytometry were conducted on peripheral blood mononuclear cells for deep immunophenotyping. Next-generation sequencing of the TCRB and IgH was performed for global immune repertoire analysis of circulating lymphocytes. Results: We identified a novel deleterious c.1455C>A (p.Y485X) mutation in LRBA. CyTOF studies demonstrated significant changes in immune landscape in the LRBA-deficient patient, including an increase in myeloid derived suppressor cells and double-negative T cells, decreased B cells, low ratio of naïve:memory T cells, and reduced capacity of T cells to secrete various cytokines following stimulation, including tumor necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ). In addition, this patient exhibited low frequency of regulatory T cells, with a reduction in their CTLA4 expression and interleukin (IL)-10 secretion. Finally, we show marked oligoclonal expansion of specific B- and T-cell clones in the peripheral blood of the LRBA-deficient patient. Conclusions: LRBA deficiency is characterized by marked immunological changes in innate and adaptive immune cells. This case highlights the importance of advanced genetic studies in patients with a unique phenotype, regardless of their age at presentation.

Physician adherence to societal guidelines following colonoscopy with polypectomy.

BACKGROUND: Colorectal cancer is a significant cause of mortality and morbidity in western countries. Polypectomy reduces the incidence and mortality of colorectal cancer. Following polypectomy, recommendations regarding the frequency and duration of surveillance rely mostly on features of the resected polyps and are summarized in various gastroenterological societal guidelines. In this study, we aimed to delineate the accuracy of current post-polypectomy surveillance recommendations and to check whether active intervention would lead to an improvement in accuracy and consistency with societal guidelines. METHODS: We prospectively collected polypectomy reports over a 3-month period in 2 tertiary medical centers. We then performed an intervention that included: 1) presentation of results from 1st phase; 2) re-affirming the guidelines in a departmental meeting; 3) addition of a dedicated reporting form for post-polypectomy surveillance recommendations in the patients' electronic medical file. Finally, we conducted a second prospective collection of post-polypectomy recommendations, over a second 3-month period. RESULTS: Prior to the intervention, 76% of the colonoscopies with polypectomy had a recommendation for surveillance, compared to 85% after the intervention (P=0.003). Prior to the intervention, 65% of patients received a recommendation consistent with societal guidelines, compared with 78% after the intervention (P=0.001). CONCLUSION: Intervention, including re-affirmation of the current guidelines and creation of a dedicated reporting platform, significantly increases the number of follow-up recommendations after polypectomy and their consistency with societal guidelines.

[DIAGNOSIS, TREATMENT AND PREVENTION OF GASTROINTESTINAL DISEASES PRE AND POST BARIATRIC SURGERY PROCEDURES].

INTRODUCTION: In the last decade, the number of bariatric surgery procedures increased dramatically in Israel similar to what has occurred worldwide. Bariatric surgery procedures have a proven efficacy in the treatment of morbid obesity. However, post-operative complications that involve the gastrointestinal tract may occur. Beyond the importance of early diagnosis and treatment, it is crucial to understand that we may decrease and prevent some of the complications by selecting the bariatric procedure according to the patient's medical background. This review addresses diagnosis, treatment and prevention of gastrointestinal diseases pre- and post-bariatric surgery procedures. Recommended pre-operative diagnostic procedures are listed including the eradication of helicobacter pylori and the protective effect of proton pump inhibitors. We reviewed the effect of specific bariatric procedures on gastroesophageal reflux disease and on intestinal motility. Prevention and treatment of nutritional deficits and metabolic complications are also discussed. Finally, this document was written by a panel of experts representing the attitudes of the Israeli Societies for Metabolic and Bariatric Surgery (ISMBS), Pharmaceutical (PSI), Study of Obesity and the Israeli Gastroenterology and Liver Diseases Association, all endorsed by the Institute for Quality in Medicine of the Israeli Medical Association (IMA).

Achieving the Recommended Gestational Weight Gain in High-Risk Versus Low-Risk Pregnancies.

BACKGROUND: Abnormal gestational weight gain (GWG) has been associated with adverse outcomes for mothers and their offspring. OBJECTIVES: To compare the achievement of recommended GWG and lifestyle factors in women with high-risk versus normal-risk pregnancies. METHODS: Pregnant women hospitalized in a gynecological and obstetrics department and pregnant women who arrived at a community clinic for a routine checkup were interviewed and completed questionnaires relating to weight gain and lifestyle factors (e.g., smoking, diet, exercise). Recommended GWG was defined by the American Congress of Obstetricians and Gynecologists (ACOG). RESULTS: GWG higher than ACOG recommendations was reported by 52/92 women (57%) with normal pregnancies and by 43/86 (50%) with high-risk pregnancies. On univariate analysis, characteristics associated with greater GWG were: current or past smoking, age > 40 years, pre-gestational body mass index (BMI) > 25 kg/m2, low fruit intake, and high snack intake. High-risk pregnancies were associated with pre-gestational BMI > 25 kg/m2 (48% vs. 27%, P = 0.012), consumption of vitamins (84% vs. 63%, P = 0.001), avoidance of certain foods (54% vs. 21%, P = 0.015), receiving professional nutritionist consultation (65% vs. 11%, P = 0.001), and less physical activity (9% vs. 24%, P = 0.01). CONCLUSIONS: A minority of pregnant women met the recommended GWG. No difference was noted between normal and high-risk pregnancies. High-risk population tended to have a less healthy lifestyle. Counseling to follow a healthy, balanced diet should be recommended, regardless of pregnancy risk, with particular attention to women at high risk of extra weight gain.

Dietary Therapy With the Crohn's Disease Exclusion Diet is a Successful Strategy for Induction of Remission in Children and Adults Failing Biological Therapy.

BACKGROUND: Loss of response [LoR] to biologics in Crohn's disease [CD] is a significant clinical problem. Dietary therapy as a treatment strategy in this setting has not been previously reported. We report the use of dietary strategies using enteral nutrition coupled with the Crohn's Disease Exclusion Diet [CDED] for LoR to infliximab or adalimumab as a single-centre experience. METHODS: Patients with LoR to a biologic despite dose escalation or combination therapy were treated with partial enteral nutrition [PEN] by a polymeric formula and the CDED for 12 weeks. Paediatric patients with severe flares received 14 days of exclusive enteral nutrition followed by PEN + CDED as above. All patients were seen at weeks 6 and 12 for follow up. Current and prior treatment, Harvey Bradshaw Index [HBI], C-reactive protein [CRP] and albumin were recorded. Remission was defined as HBI <5 at week 6. RESULTS: Twenty-one patients, mean age 22.1 ± 8.9 years [11 adults and ten children] met study criteria. Seventeen patients [81%] had used combination therapy, and 10/21 [47.6%] had failed a second biologic. Seven patients had a prior intestinal resection. Dose escalation had failed in 13/21 [62%] patients. Clinical remission by physician's global assessment and HBI after 6 weeks was obtained in 13/21 [61.9%]. Mean HBI decreased from 9.4 ± 4.2 to 2.6 ± 3.8 [p < 0.001], mean CRP decreased from 2.8 ± 3.4 to 0.7 ± 0.5 [p = 0.005] and mean albumin increased from 3.5 ± 0.6 to 3.8 ± 0.5 [p = 0.06]. CONCLUSION: Dietary treatment combining PEN with the CDED may be a useful salvage regimen for patients failing biological therapy despite dose escalation.

Gestational Weight Gain and Its Relationship with Maternal Characteristics.

BACKGROUND: Both high and insufficient weight gain during pregnancy have been associated with adverse outcomes for mothers and their offspring. OBJECTIVES: To describe self-reported weight gain during pregnancy, assess the concurrence of this weight gain with issued recommendations, and investigate associations between lifestyle factors and weight gain. METHODS: In this cross-sectional study, 109 pregnant women hospitalized in one gynecological and obstetrics department completed questionnaires related to weight gain and lifestyle factors such as smoking, diet and exercise. Recommended weight gain was defined by the American Congress of Obstetricians and Gynecologists and was compatible with the Ministry of Health guidelines in Israel. RESULTS: Fifty-three (49%) participants reported weight gain above the recommendation, 31 (28%) met the recommendations and 25 (23%) reported weight gain below the recommendations. Characteristics associated with high weight gain included past smoking and/or age above 36 years and/or body mass index (BMI) above 25 kg/m2. Only 34 women (31%) reported seeking professional nutritional counseling during pregnancy. An increased tendency to consult a nutritionist was reported among diabetic women. CONCLUSIONS: Only a minority of women gained the recommended weight during pregnancy. High BMI and/or a history of smoking and/or older age were associated with weight gain above recommendations. Particular effort should be directed toward counseling women at high risk of weight gain during pregnancy.

Nurse's perceptions of barriers to optimal nutritional therapy for hospitalized patients.

BACKGROUND & AIMS: Nurses have crucial roles in optimizing nutritional therapy for patients. The aim of this study was to explore nurses' perceptions regarding barriers to effective nutritional therapy. METHODS: Hospital-based nurses completed a questionnaire regarding various aspects of malnutrition/risk identification and barriers to effective nutritional treatment. The study was conducted at Rambam Health Care Campus with 100 nurses completing the questionnaire. RESULTS: Eighty-eight percent of those surveyed perceived identification of patients at risk for malnutrition as the nurse's responsibility. Significant differences were found when comparing head vs. bedside nurses regarding recognition of barriers to optimal nutritional therapy. More than 40% of the nurses found that the following issues were significant barriers to optimal patient treatment: the time it takes to prescribe nutritional therapy, lack of protocols, and awareness of the staff of the nutritional therapy. Overall bedside nurses found significantly more barriers preventing optimal nutritional therapy than did head nurses. CONCLUSIONS: Barriers to optimal nutrition are often remediable. Head nurses set ward policies but had a significantly different perception of barriers to nutritional care than bedside nurses. Collaboration is imperative for all sectors and authorities involved in patient care, including bedside nurses, to ensure that workable policies are implemented for the patients' benefit.

Micronutrient deficiencies in inflammatory bowel disease.

PURPOSE OF REVIEW: Malnutrition, protein-energy, and micronutrient deficiencies are common among patients with inflammatory bowel disease (IBD). The deficiencies are a manifestation of the complicated disease and a cause of morbidity. The present review summarizes recent advances and evidence-based knowledge regarding micronutrients in relation to patients with IBD. RECENT FINDINGS: Micronutrient deficiencies occur in more than half of patients with IBD. Most common are deficiencies of iron, B12, vitamin D, vitamin K, folic acid, selenium, zinc, vitamin B6, and vitamin B1. Deficiencies are more common in Crohn's disease than in ulcerative colitis, and more in active disease than at times of remission. Micronutrient deficiency is associated with prolonged and complicated course of disease. Iron deficiency is the most common cause for anemia. Definite diagnosis of B12 deficiency cannot be established by serum levels alone. Vitamin D and vitamin K deficiencies are thought to be associated with heightened inflammatory state. The relationship of these deficiencies with bone disease is controversial. The present review focuses on the significance, epidemiology, treatment options, and recommendations regarding micronutrient deficiencies in IBD. SUMMARY: Micronutrient deficiencies are common and have clinical significance. High suspicion for micronutrient deficiencies is advocated so that treatable causes of morbidity are treated appropriately and late and irreversible sequlae are prevented.

Malnutrition in cardiac surgery: food for thought.

BACKGROUND: Undernourished patients treated in general surgery departments suffer from prolonged and complicated hospitalizations, and higher mortality rates compared with well nourished patients. Pivotal information regarding patients' nutritional status and its effect on clinical outcome is lacking for cardiac surgery patients. We investigated the prevalence of malnutrition risk and its association with 30-day hospital mortality and postoperative complications. METHODS AND RESULTS: Four hundred and three patients who underwent cardiac surgery during 2008 and were screened with the Malnutrition Universal Screening Tool (MUST) on admission were enrolled. Univariate and multivariate logistic regression analyses compared the association of high and low risk for malnutrition with length of hospitalization (LOS), in-hospital and 30-day mortality, and postoperative complications. Almost 20% of the patients were found to be at high risk for malnutrition. Univariate analyses revealed higher in-hospital mortality rates (p = 0.03) and greater incidence of LOS and antibiotic treatment longer than 21 days (p = 0.002 and p = 0.04, respectively), vasopressor treatment longer than 11 days (p = 0.02), and positive blood cultures (p = 0.02) in patients belonging to the high-risk MUST group. Incorporation of the MUST in a multivariate model with the European System for Cardiac Operative Risk Evaluation (EuroSCORE) significantly improved postoperative complications prediction, as well as in-hospital and 30-day mortality, compared with the EuroSCORE alone. CONCLUSIONS: Malnutrition is prevalent in patients undergoing cardiac surgery, associated with higher postoperative mortality and morbidity. Preoperative MUST screening has emerged as highly relevant for enabling early diagnosis of patients at malnutrition risk, predicting postoperative mortality and morbidity, thus promoting well timed treatment. Prospective studies are needed to explore whether intervention can decrease malnutrition risk.

Thiopurine effectiveness in patients with Crohn's disease: a study of genetic and clinical predictive factors.

BACKGROUND: Thiopurines are efficacious in the treatment of Crohn's disease and were recently shown to induce T-cell apoptosis by modulation of Rac1 activation. To assess whether polymorphisms in Rac1 and other apoptosis-related genes, combined with clinical parameters, can predict response to thiopurines. METHODS: A retrospective cohort of 156 thiopurine-treated patients with Crohn's disease was genotyped for 11 single-nucleotide polymorphisms (SNPs): 9 SNPs in Rac1, 1 SNP in the Fas ligand -843 T>C, and 1 SNP in the Caspase-9 93 C>T. Clinical data were extracted from the medical charts. Odds ratios (ORs) and 95% confidence intervals (CIs) of the association between demographic, clinical, and genetic variables and thiopurine response rates were calculated. RESULTS: The overall response rate to thiopurines was 74% (115/156). The Rac1 SNP rs34932801 heterozygote genotype GC was associated with a lower response rate compared with the wild-type GG genotype (46% versus 76%; OR = 0.26; 95% CI, 0.08-0.91; P = 0.036). Only wild-type homozygotes were found for 5 Rac1 SNPs. None of the other 3 Rac1 SNPs were associated with response to thiopurines. Patients with Montreal B3 behavior pattern responded worse than those with a B1 behavior pattern (59%, versus 80%; OR = 0.37; 95% CI, 0.17-0.83; P = 0.016). Sephardic Jews had a lower response rate to thiopurines compared with Jews of Ashkenazi or mixed ancestry (60% versus 82%; OR = 0.32; 95% CI, 0.15-0.69, P = 0.003). CONCLUSIONS: Rac1 SNP rs34932801carriage, Montreal B3 disease behavior, and a Sephardic Jewish origin were associated with unfavorable response to thiopurines. Corroboration of these associations in larger cohorts is warranted.

Maternal inflammatory bowel disease has short and long-term effects on the health of their offspring: a multicenter study in Israel.

BACKGROUND: There are concerns about the effect of inflammatory bowel diseases (IBD) on fertility, pregnancy and pregnancy outcomes, but no long-term data on the health of offspring born to IBD mothers. The aims were to assess the short- and long-term effects of maternal IBD on the morbidity and development of their offspring. METHODS: Female IBD patients and controls completed questionnaires on their pregnancy outcome, and their offspring's short- and long-term health and development. RESULTS: IBD and control mothers (159 and 175, respectively) were recruited. Medical data of 412 IBD and 417 control offspring were recorded. IBD mothers had significantly more singleton pregnancies, their offspring's birth weight was significantly lower, and they breastfed significantly less compared to controls (P=0.028, 0.007, and <0.0001, respectively). There were significantly more congenital anomalies (mainly limb deformities) among the IBD offspring (P<0.035). Offspring born post-maternal IBD diagnosis, compared to pre-diagnosis, tended to have more neurodevelopmental problems (e.g., gross motor delay, P=0.03). IBD was significantly more prevalent in the offspring of IBD mothers, while allergies and atopic dermatitis were more frequent in offspring of control mothers. More offspring of IBD mothers taking medications during pregnancy were born preterm and had lower birth weights compared to offspring of IBD mothers not taking medications during pregnancy. Children of mothers taking steroids had the lowest birth weights, compared to those of IBD mothers taking 5ASAs or immunomodulators. CONCLUSIONS: Maternal IBD affects pregnancy and the offspring's immediate and long-term morbidity, specifically, congenital anomalies and neurodevelopmental problems.

Proactive screening in Israel identifies alarming prevalence of malnutrition among hospitalized patients--action is needed.

OBJECTIVE: Malnourished patients suffer from higher morbidity and mortality rates than well-nourished patients do. However, few studies have controlled the outcomes for the underlying illnesses. Our aim was to determine the prevalence of malnutrition among patients admitted to the internal medicine ward and to determine whether malnutrition is an independent risk factor for adverse outcomes in these settings. METHODS: Consecutive patients screened for malnutrition with the MUST (Malnutrition Universal Screening Tool), admitted to an internal medicine department, were included in this study. Demographic data, background disease, laboratory results, length of stay, and mortality rates were retrieved from the computerized file and Charlson Comorbidity Index (CCI) was calculated. Univariate and multivariate analyses were used to check for the association of malnutrition and outcome measures. RESULTS: One thousand consecutive patients were included in the study. Mean age was 67.6 y; 25.4% of patients were found to be at high risk for malnutrition. Patients at high risk for malnutrition had significantly longer length of stay and mortality rates than well-nourished patients (9.7 d versus 6.2 d and 19.3% versus 3.2%; accordingly [P < 0.001]). On multivariate analyses, increased mortality was found to be associated with a high risk for malnutrition as well as pneumonia, acute myocardial infarction, acute renal failure, or shock on admission and a high CCI score. CONCLUSION: The prevalence of malnutrition among hospitalized patients, as measured by the MUST score, is common. Malnutrition is prevalent and represents an independent and significant risk factor for in-hospital mortality and increased length of stay in patients admitted to the internal medicine ward.
