Lifestyle Factors and Early Clinical Outcome in Patients With Acute Stroke: A Population-Based Study.

BACKGROUND AND PURPOSE: We examined the associations of individual and combined lifestyle factors with early adverse stroke outcomes. METHODS: A total of 82 597 patients were identified from nationwide registries. Lifestyle factors at the time of stroke admission included body mass index (kg/m2), smoking habits, and alcohol intake, which were grouped (healthy, moderately healthy, moderately unhealthy, and unhealthy). The associations between lifestyle and outcomes were examined using multivariable regression. RESULTS: A total of 18.3% had a severe stroke, 7.8% pneumonia, 12.5% urinary tract infection, and 9.9% died within 30 days. The association between lifestyle, stroke severity, and mortality, respectively, differed according to sex. Unhealthy lifestyle was associated with lower risk of severe stroke (adjusted odds ratio [OR], 0.73; 95% confidence interval [CI], 0.63-0.84) and 30-day mortality among men (adjusted OR, 0.71; 95% CI, 0.58-0.87), but not among women (severe stroke: adjusted OR, 1.14; 95% CI, 0.85-1.55, and mortality: adjusted OR, 1.34; 95% CI, 0.90-1.99). No sex differences were found for pneumonia and urinary tract infection. Unhealthy lifestyle was not associated with a statistically significant increased risk of developing in-hospital pneumonia (adjusted OR, 1.30; 95% CI, 0.98-1.73) or urinary tract infection (adjusted OR, 0.98; 95% CI, 0.72-1.33). Underweight was associated with a higher 30-day mortality (men: adjusted OR, 1.71; 95% CI, 1.50-1.96, and women: adjusted OR, 1.46; 95% CI, 1.34-1.60). CONCLUSIONS: Healthy lifestyle was not associated with a lower risk of adverse stroke outcomes, in particularly among men. However, underweight may be a particular concern being associated with an increased risk of adverse outcomes among both sexes.

Pulmonary rehabilitation: A cohort study assessing the effectiveness of a multi-professional nutrition intervention.

BACKGROUND: Limited benefit of pulmonary exercise rehabilitation has been associated with fulfilment of energy and protein requirements. OBJECTIVES: The aim was to enhance dietary intake towards requirements and to maintain changes after a pulmonary rehabilitation program. METHODS: This single arm intervention study included multidisciplinary focus on nutrition and three sessions of individual dietary counselling during a 10-week pulmonary exercise rehabilitation in five municipalities centers. Data were collected at baseline (P0), at the end of intervention (P1) and for two municipalities at three months post intervention (P2). RESULTS: Of the 111 included participants, (mean age 70.8 (±9)) 99 (89%) completed the rehabilitation including the three individual dietary counselling's. A very large variation in body composition including body mass index and exercise abilities was found. Protein intake improved from 64 (±22 g) (P0) to 88 (±25 g) (P1) (p < 0.001) and energy intake from 1676 (±505 kcal) (P0) to 1941 (±553 kcal) (p < 0.001) (P1) and Muscle Mass Index increased from 10.6 (±3.2) (P0) to 10.9 (±3.2) (P1) (p = 0.007); number of 30 s chair stand test improved from 10.9 (±2.8) repetitions (P0) to 14.1 (±4.3) repetitions (P1) (p < 0.001), distance in six-minut walking test improved from 377.2 (±131.2 m) (P0) to 404.1 (±128.6 m) (P1) (p < 0.001). Two municipalities completed the three months follow-up. For those, dietary improvements remained stable, including protein intake. CONCLUSION: Including three sessions of dietary counselling in a multi-professional effort was associated with improved individualized dietary intake, as well as physical function. Benefits remained almost unchanged after three months. Improvements in function could not be fully explained by improved intakes.

Cancer risk in inflammatory bowel disease according to patient phenotype and treatment: a Danish population-based cohort study.

OBJECTIVES: Population-based studies of site-specific cancer risk in patients with inflammatory bowel disease (IBD) according to IBD phenotype and treatment are lacking. We studied cancer risk in a well-characterized population-based IBD cohort from North Jutland County, Denmark. METHODS: A total of 1,515 patients were diagnosed with ulcerative colitis (UC) and 810 with Crohn's disease (CD) during 1978-2002. Patients were followed until 31 December 2010 for occurrence of incident cancer, identified in the Danish Cancer Registry. Observed numbers of cancer were compared with expected numbers (based on age- and sex-specific background rates) and presented as standardized incidence ratios (SIRs) with 95% confidence intervals (CIs). RESULTS: Patients with UC were not at increased risk of cancer overall (SIR, 1.12; 95% CI, 0.97-1.28) despite increased risk of prostate cancer (SIR, 1.82; 95% CI, 1.17-2.71). Patients with CD had a 55% increased risk of cancer overall (SIR, 1.55; 95% CI, 1.29-1.84) related to young age, colonic disease, smoking, and thiopurine exposure. Patients were at increased risk of small bowel cancer (SIR, 15.18; 95% CI, 1.84-54.78), lung cancer (SIR, 2.13; 95% CI, 1.19-3.52 (associated with female gender and smoking)), colorectal cancer in males (SIR, 2.43; 95% CI, 1.05-4.78), cervical dysplasia (SIR, 1.65; 95% CI, 1.10-2.37 (associated with young age at diagnosis, smoking, 5-aminosalicylic acid, and thiopurine exposure)), and non-Hodgkin lymphoma (SIR, 3.43; 95% CI, 1.38-7.07 (unrelated to thiopurine exposure)). CONCLUSIONS: Patients with CD, but not UC, have an overall excess risk of cancer. Clinical characteristics of IBD patients at excess risk differ by cancer subtype.

Prevalence of sarcopenia in patients with chronic intestinal failure-how are SARC-F and the EWGSOP algorithm associated before and after a physical exercise intervention.

INTRODUCTION: Patients with chronic intestinal failure (IF) have a low degree of physical activity, decreased muscle mass, and decreased muscle strength, leading to a high risk of sarcopenia. We aimed to test the prevalence of sarcopenia by the use of SARC-F and EWGSOP and to investigate the association between the two at baseline and after 12 weeks of an exercise intervention. METHODS: Thirty-one patients with chronic IF completed 12 weeks of three weekly home-based individualized exercise sessions. Body composition was measured by bioimpedance analysis and physical function by handgrip strength (HGS) and timed up-and-go (TUG). Sarcopenia was assessed by SARC-F and EWGSOP. Multiple regression analysis was used to test for the association between the two tools. RESULTS: The prevalence of sarcopenia measured by EWGSOP was 59%. This prevalence did not change after the intervention. At baseline, 38.8% of patients were screened as at risk for sarcopenia by SARC-F. This decreased to 29.0% after the intervention (P < 0.001). A statistically significant increase was achieved in muscle mass (P = 0.017) and muscle mass index (P = 0.016). Furthermore, both TUG (P = 0.033) and HGS (P = 0.019) improved. CONCLUSIONS: Sarcopenia is prevalent in patients with chronic IF. EWGSOP finds more patients to be at risk of sarcopenia than SARC-F but was not sufficiently sensitive to measure changes induced by the physical intervention. The significant change in SARC-F may illustrate that patients, themselves, find an improvement in self-perceived health.

COVID-19 infection in patients on long-term home parenteral nutrition for chronic intestinal failure.

BACKGROUND AND AIMS: To investigate the incidence and the severity of COVID-19 infection in patients enrolled in the database for home parenteral nutrition (HPN) for chronic intestinal failure (CIF) of the European Society for Clinical Nutrition and Metabolism (ESPEN). METHODS: Period of observation: March 1st, 2020 March 1st, 2021. INCLUSION CRITERIA: patients included in the database since 2015 and still receiving HPN on March 1st, 2020 as well as new patients included in the database during the period of observation. Data related to the previous 12 months and recorded on March 1st 2021: 1) occurrence of COVID-19 infection since the beginning of the pandemic (yes, no, unknown); 2) infection severity (asymptomatic; mild, no-hospitalization; moderate, hospitalization no-ICU; severe, hospitalization in ICU); 3) vaccinated against COVID-19 (yes, no, unknown); 4) patient outcome on March 1st 2021: still on HPN, weaned off HPN, deceased, lost to follow up. RESULTS: Sixty-eight centres from 23 countries included 4680 patients. Data on COVID-19 were available for 55.1% of patients. The cumulative incidence of infection was 9.6% in the total group and ranged from 0% to 21.9% in the cohorts of individual countries. Infection severity was reported as: asymptomatic 26.7%, mild 32.0%, moderate 36.0%, severe 5.3%. Vaccination status was unknown in 62.0% of patients, non-vaccinated 25.2%, vaccinated 12.8%. Patient outcome was reported as: still on HPN 78.6%, weaned off HPN 10.6%, deceased 9.7%, lost to follow up 1.1%. A higher incidence of infection (p = 0.04), greater severity of infection (p < 0.001) and a lower vaccination percentage (p = 0.01) were observed in deceased patients. In COVID-19 infected patients, deaths due to infection accounted for 42.8% of total deaths. CONCLUSIONS: In patients on HPN for CIF, the incidence of COVID-19 infection differed greatly among countries. Although the majority of cases were reported to be asymptomatic or have mild symptoms only, COVID-19 was reported to be fatal in a significant proportion of infected patients. Lack of vaccination was associated with a higher risk of death.

Can the patient perspective contribute to quality of nutritional care?

AIM: Undernutrition has been seen in hospitalized patients at all times. Nurses have a central position in the nutritional care of the patient. Despite guidelines for nutritional practise and care, 20-55% of patients are still at risk of complications to insufficient nutrition intake. The aim of this study was to obtain knowledge of hospitalized patient's experiences of being undernourished, to understand implications this might have to quality of nutritional nursing care. METHODS: Qualitative interviews were undertaken in 12 hospitalized patients at severe nutritional risk. FINDINGS: Pain, no appetite, bad taste and side effects to medication were among reasons for poor eating. Nurses practically did not address or question symptoms that could influence poor eating and were only to a low degree involved at patient initiative. The patients appeared to divide into two groups; One 'Passive group', characterized with fatigue, lack of concentration and short term memory, were found insusceptible to increase nutrition intake by motivation and guidance. The overall motivation in the other 'Active' group was the setting of and achievement of goals, which had to be clear, communicated and followed up by nurses and physicians. This group furthermore found self-determination and active involvement determinant for a positive and fruitful cooperation between staff and themselves. CONCLUSIONS: Nurses were in progressive about clarifying why patients did not eat. Patients highly regarded nutrition registration when followed up, however, this was only practised to a low degree. Severely undernourished patients could be divided in two groups. The 'Passive group' should be attended to systematically. Artificial nutrition is often needed in this group. The 'Active group' should be cared for with individual, active involvement from nurses. Nurses should be able to distinct which nutritional care for which patient, and act upon it.

Reducing Disease Activity of Inflammatory Bowel Disease by Consumption of Plant-Based Foods and Nutrients.

Inflammatory bowel disease is a chronic and recurring inflammatory condition of the gastrointestinal tract encompassing ulcerative colitis and Crohn's disease. Although the pathogenesis of inflammatory bowel disease remains to be fully elucidated, environmental factors such as diet are believed to play a pivotal role in the onset and management of inflammatory bowel disease. Diet is thought to play an essential role in intestinal inflammation due to its regulatory effects on the microbiota, gut immune system, and epithelial barrier function. Although the evidence remains insufficient to draw firm conclusions on the role of specific dietary components in gastrointestinal diseases, studies have suggested that a Western diet with high intakes of total fats, omega-6 fatty acids, and meat have been associated with intestinal inflammation and relapse of inflammatory bowel disease. In contrast to a Western diet, plant-based diets often result in a reduced intake of total fats and meats and an increased intake of plant fibers which may contribute to reduced intestinal inflammation. This review critically examines the influence of plant-based dietary components on the clinical disease course of inflammatory bowel disease. Furthermore, this review discusses the benefits and possible limitations of plant-derived dietary components in the treatment of inflammatory bowel disease while addressing the principal type of disease and the anatomic site of inflammation within the gastrointestinal tract. Finally, this review points out important directions for future research on the role of diet in inflammatory bowel disease. A better understanding of the role of diet and intestinal inflammation may pave the way for novel dietary interventions and specific foods- or food supplements, which can support the treatment of inflammatory bowel disease.

Feasibility of a multimodal intervention on malnutrition in patients with lung cancer during primary anti-neoplastic treatment.

BACKGROUND: Wasting of body mass and skeletal muscle frequently develops in patients with cancer and is associated with impaired functional ability and poor clinical outcome and quality of life. This study aimed to evaluate the feasibility and explore the effect of a multimodal intervention targeting nutritional status in patients with non-small cell lung cancer receiving primary anti-neoplastic treatment. Additionally, predictive and prognostic factors of gaining skeletal muscle were explored. METHODS: This was a single-centre multimodal intervention trial using a historical control group. The multimodal intervention involved fish oil intake (2 g of eicosapentaenoic acid or docosahexaenoic acid daily), regular dietary counselling and unsupervised physical exercise twice weekly during the first three cycles of primary anti-neoplastic treatment. Feasibility was assessed through recruitment rate, completion rate and compliance rate with the intervention. Differences in skeletal muscle, body weight, and physical function between the intervention and historical control groups were analysed. Factors contributing to increased skeletal muscle were explored using univariate and multivariate ordinal logistic regression analyses. RESULTS: The recruitment and completion rates were 0.48 (n = 59/123) and 0.80 (n = 46/59), respectively. The overall compliance rate with all five individual interventions was 0.60 (n = 28/47). The individual compliance rates were 0.81 (n = 38/47) with fish oil intake, 0.94 (n = 44/47) with energy intake, 0.98 (n = 46/47) with protein intake, 0.51 (n = 24/47) with resistance exercise and 0.57 (n = 27/47) with aerobic exercise. No mean differences in skeletal muscle, body weight, or physical function were found between the intervention and control groups. However, a larger proportion of patients in the intervention group gained skeletal muscle (p < 0.02). The identified contributing factors of muscle gain were weight gain (OR, 1.3; p = 0.01), adherence to treatment plan (OR, 4.6; p = 0.02), stable/partial response (OR, 3.3; p = 0.04) and compliance to the intervention (OR, 7.4; p = 0.01). Age, sex, tumour stage, performance status, treatment type and baseline cachexia did not predict muscle gain. CONCLUSION: This three-dimensional intervention in patients with lung cancer undergoing primary anti-neoplastic treatment was feasible and increased the proportion of patients gaining skeletal muscle. Dietary counselling and fish oil use were useful strategies. The motivation for conducting unsupervised physical intervention was low. Clinical trials.gov identifier: NCT04161794.

Characteristics of adult patients with chronic intestinal failure due to short bowel syndrome: An international multicenter survey.

BACKGROUND AND AIMS: The case-mix of patients with intestinal failure due to short bowel syndrome (SBS-IF) can differ among centres and may also be affected by the timeframe of data collection. Therefore, the ESPEN international multicenter cross-sectional survey was analyzed to compare the characteristics of SBS-IF cohorts collected within the same timeframe in different countries. METHODS: The study included 1880 adult SBS-IF patients collected in 2015 by 65 centres from 22 countries. The demographic, nutritional, SBS type (end jejunostomy, SBS-J; jejuno-colic anastomosis, SBS-JC; jejunoileal anastomosis with an intact colon and ileocecal valve, SBS-JIC), underlying disease and intravenous supplementation (IVS) characteristics were analyzed. IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorized as <1, 1-2, 2-3 and >3 L/day. RESULTS: In the entire group: 60.7% were females and SBS-J comprised 60% of cases, while mesenteric ischaemia (MI) and Crohn' disease (CD) were the main underlying diseases. IVS dependency was longer than 3 years in around 50% of cases; IVS was infused ≥5 days/week in 75% and FE in 10% of cases. Within the SBS-IF cohort: CD was twice and thrice more frequent in SBS-J than SBS-JC and SBS-JIC, respectively, while MI was more frequent in SBS-JC and SBS-JIC. Within countries: SBS-J represented 75% or more of patients in UK and Denmark and 50-60% in the other countries, except Poland where SBS-JC prevailed. CD was the main underlying disease in UK, USA, Denmark and The Netherlands, while MI prevailed in France, Italy and Poland. CONCLUSIONS: SBS-IF type is primarily determined by the underlying disease, with significant variation between countries. These novel data will be useful for planning and managing both clinical activity and research studies on SBS.

High risk of disease-related malnutrition in gastroenterology outpatients.

OBJECTIVE: Disease-related malnutrition (DRM) in hospitalized patients is known to have significant negative impact on clinical outcomes. Meanwhile, DRM in gastroenterology outpatients is scarcely investigated. The aim of this study was to investigate the prevalence of unintentional weight loss (UWL) and reduced food intake (RFI) as contributors to the risk of DRM in outpatients. Furthermore, the aim was to investigate if UWL may be used as initial screening for DRM, based on the correlation between UWL and RFI. METHODS: All outpatients visiting the clinics for Medical and Surgery Gastroenterology, Aalborg University Hospital, Denmark, during 1 wk in September 2018, were invited to participate. Data regarding UWL within the past 3 mo, RFI the past week, and nutritional impact symptoms (NIS) were collected in this questionnaire-based cross-sectional study. Descriptive analysis, χ2 test, and multiple logistic regression analysis were used for statistics. RESULTS: Out of 348 eligible patients, 346 were included at the medical clinic (n = 170) and surgery clinic (n = 176). UWL occurred in 26%, with a mean weight loss of 7.1 kg (standard deviation [SD] 5.2), and 24% had RFI. A significantly increased risk of UWL was identified in patients with body mass index <18.5 kg/m2 (odds ratio 6.1; confidence interval 2.0-18.7; P = 0.003). NIS were more common in the medical clinic. The main self-reported reasons for NIS affecting UWL were lack of appetite (15% versus 12%), pain (14% versus 8%), and nausea (12% versus 3%). CONCLUSIONS: One in four outpatients experienced UWL to an extent that may have a significant negative impact on clinical outcome. A firm correlation was found between UWL and RFI. Thus, based on this superficial study, UWL may be used as initial screening for protein-energy malnutrition in the medical and surgery gastroenterology outpatient setting. The impact on clinical outcome and of early nutritional intervention in these settings need to be investigated.

Home parenteral nutrition provision modalities for chronic intestinal failure in adult patients: An international survey.

BACKGROUND & AIMS: The safety and effectiveness of a home parenteral nutrition (HPN) program depends both on the expertise and the management approach of the HPN center. We aimed to evaluate both the approaches of different international HPN-centers in their provision of HPN and the types of intravenous supplementation (IVS)-admixtures prescribed to patients with chronic intestinal failure (CIF). METHODS: In March 2015, 65 centers from 22 countries enrolled 3239 patients (benign disease 90.1%, malignant disease 9.9%), recording the patient, CIF and HPN characteristics in a structured database. The HPN-provider was categorized as health care system local pharmacy (LP) or independent home care company (HCC). The IVS-admixture was categorized as fluids and electrolytes alone (FE) or parenteral nutrition, either commercially premixed (PA) or customized to the individual patient (CA), alone or plus extra FE (PAFE or CAFE). Doctors of HPN centers were responsible for the IVS prescriptions. RESULTS: HCC (66%) was the most common HPN provider, with no difference noted between benign-CIF and malignant-CIF. LP was the main modality in 11 countries; HCC prevailed in 4 European countries: Israel, USA, South America and Oceania (p < 0.001). IVS-admixture comprised: FE 10%, PA 17%, PAFE 17%, CA 38%, CAFE 18%. PA and PAFE prevailed in malignant-CIF while CA and CAFE use was greater in benign-CIF (p < 0.001). PA + PAFE prevailed in those countries where LP was the main HPN-provider and CA + CAFE prevailed where the main HPN-provider was HCC (p < 0.001). CONCLUSIONS: This is the first study to demonstrate that HPN provision and the IVS-admixture differ greatly among countries, among HPN centers and between benign-CIF and cancer-CIF. As both HPN provider and IVS-admixture types may play a role in the safety and effectiveness of HPN therapy, criteria to homogenize HPN programs are needed so that patients can have equal access to optimal CIF care.

Exploring the dietary protein intake and skeletal muscle during first-line anti-neoplastic treatment in patients with non-small cell lung cancer.

BACKGROUND: Loss of skeletal muscle mass is the corner stone of cancer cachexia, but no effective therapies are yet identified. The optimal protein quantity and pattern to support muscle mass maintenance in cancer patients is unknown. The aim of the current exploratory study was to observe the pattern and quantity of dietary protein intake as well as the prevalence of muscle wasting in patients with inoperable non-small cell lung cancer (NSCLC) undergoing primary anti-neoplastic treatment. The secondary aim was to assess the potential contributory factors associated with maintenance of muscle mass. METHOD: A longitudinal observational study was conducted in patients with NSCLC undergoing first line of anti-neoplastic treatment. Nutrient intake was assessed by repeated 24-h recalls and skeletal muscle by routine thoraco-abdominal CT scans at baseline and after three cycles of treatment. Descriptive analyses, paired samples t-test, binomial logistic and linear regression analyses were performed. RESULTS: Out of 186 consecutively screened patients, 62 were included and 52 patients were available for analysis. Protein intake increased from baseline to follow up, but were lower in muscle wasters (1.0 g/kg/d) than in muscle maintainers (1.4 g/kg/d). The majority of the meals contributed less than 20 g of protein and less than 10% of the meals contributed at least 40 g of protein. Significant loss of skeletal muscle area was observed in 26 out of 52 patients. A higher protein intake (OR 18.7, p = 0.01), energy intake (OR 1.1, p = 0.04) and stable body weight (OR 1.2, p = 0.03) were associated with muscle maintenance in the univariate regression, whereas age, sex, cachexia, tumour stage, treatment adherence and response did not. In the multivariate regression, a trend was seen for protein intake (OR 35.2, p = 0.08) and body weight (OR 1.2, p = 0.06). CONCLUSION: Muscle wasting occurred frequently and early during primary anti-neoplastic treatment. Protein intake seems important for maintaining skeletal muscle. Validated dietary methods in cancer patients must be identified and the optimal protein quantity and intake pattern to support muscle maintenance should be explored in future trials.

Restoration of enteroendocrine and pancreatic function after internal hernia and short bowel syndrome in a young woman with gastric bypass - a 2-year follow-up.

A serious complication to the laparoscopic Roux-en-Y gastric bypass (RYGB) is internal hernia, which can lead to massive bowel necrosis that may result in short bowel syndrome. We determined postprandial enteropancreatic hormonal responses and metabolites in a 22-year-old nondiabetic woman with a history of RYGB experiencing severe internal herniation with widespread bowel necrosis. Extensive resections were performed leaving her with a saliva fistula from the pouch-enteric anastomosis, an intact duodenum, 15 cm of jejunum, 35 cm of ileum, and intact colon. Parenteral nutrition was initiated and 10 months after the bowel resection, intestinal continuity was re-established. After 6 weeks the patient reached parenteral nutrition independence. She underwent standardized liquid mixed meal tests before, 3 months after and 2 years after intestinal continuity was re-established. Gut hormone responses were completely restored postoperatively leading to very high concentrations in plasma. After 2 years, plasma concentrations had, however, decreased markedly, suggesting desensitization of the gut ostensibly in response to chronic hyperstimulation. There was no evidence of cephalic phase insulin secretion.

Clinical classification of adult patients with chronic intestinal failure due to benign disease: An international multicenter cross-sectional survey.

BACKGROUND & AIMS: The aim of the study was to evaluate the applicability of the ESPEN 16-category clinical classification of chronic intestinal failure, based on patients' intravenous supplementation (IVS) requirements for energy and fluids, and to evaluate factors associated with those requirements. METHODS: ESPEN members were invited to participate through ESPEN Council representatives. Participating centers enrolled adult patients requiring home parenteral nutrition for chronic intestinal failure on March 1st 2015. The following patient data were recorded though a structured database: sex, age, body weight and height, intestinal failure mechanism, underlying disease, IVS volume and energy need. RESULTS: Sixty-five centers from 22 countries enrolled 2919 patients with benign disease. One half of the patients were distributed in 3 categories of the ESPEN clinical classification. 9% of patients required only fluid and electrolyte supplementation. IVS requirement varied considerably according to the pathophysiological mechanism of intestinal failure. Notably, IVS volume requirement represented loss of intestinal function better than IVS energy requirement. A simplified 8 category classification of chronic intestinal failure was devised, based on two types of IVS (either fluid and electrolyte alone or parenteral nutrition admixture containing energy) and four categories of volume. CONCLUSIONS: Patients' IVS requirements varied widely, supporting the need for a tool to homogenize patient categorization. This study has devised a novel, simplified eight category IVS classification for chronic intestinal failure that will prove useful in both the clinical and research setting when applied together with the underlying pathophysiological mechanism of the patient's intestinal failure.

Increase in incidence and prevalence of inflammatory bowel disease in northern Denmark: a population-based study, 1978-2002.

OBJECTIVES: Although incidence rates of inflammatory bowel disease have been reported worldwide, few long-term population-based studies with current time-trend analyses exist. We therefore examined time trends in the incidence rate of inflammatory bowel disease in a 25-year study period, and estimated the prevalence in 2002. All patients diagnosed between 1978 and 2002 were included as incident cases (n=2,326) and all patients living in North Jutland County on 31 December 2002 were used to estimate prevalent cases (n=2,205). METHODS: Medical records of all patients diagnosed with ulcerative colitis and Crohn's disease in the North Jutland County Hospital Discharge Registry were reviewed to examine if the diagnostic criteria were fulfilled. Age-specific and gender-specific standardized incidence rates were calculated. RESULTS: For ulcerative colitis, incidence rates in women increased from 8.3 (95% confidence interval (CI): 6.7-9.9) in 1978-1982 to 17.0 (95% CI: 14.7-19.3) per 100,000 person-years in 1998-2002. The corresponding figures for men were 7.7 (95% CI: 6.1-9.3) and 16.7 (95% CI: 14.4-18.8) per 100,000 person-years. For Crohn's disease, the incidence rates in women increased from 4.1 (95% CI: 3.0-5.2) in 1978-1982 to 10.7 (95% CI: 8.8-12.5) per 100,000 person-years in 1998-2002. The corresponding figures for men were 3.2 (95% CI: 2.1-4.2) and 8.5 (95% CI: 6.9-10.2) per 100,000 person-years. The prevalence of ulcerative colitis and Crohn's disease was 294 and 151 per 100,000 inhabitants, respectively. CONCLUSIONS: A marked and parallel increase was seen in both ulcerative colitis and Crohn's disease in both genders during the last 25 years, with a corresponding high prevalence of both diseases.

Advances in clinical nutrition in GI surgery.

This review addresses recent relevant advances to clinical nutrition regarding gastrointestinal disease surgery. Medline Ovid, EMBASE and Central were searched systematically in April 2014. Inclusion criteria were randomized controlled trials, non-randomized controlled trials and observational studies evaluating nutritional support in gastrointestinal surgery published within 5 years. The review included 56 relevant studies. Themes were: nutrition screening and risk factors predict outcome; preoperative nutritional support; shortening fasting periods and including carbohydrate solutions; early nutrition after surgery; immune modulating nutrition; synbiotics, growth hormone, omega-3 and oral, enteral and parenteral nutrition in combination. Screening for nutritional risk is profound, with special focus on dietary intake in the past week. Age and severity of disease need to be included in the screening system. Patients at severe nutritional risk benefit from nutritional therapy before surgery. New standards are developing quickly and clinical guidelines on surgery should include updated knowledge within clinical nutrition.

Effects of perioperative supplementation with omega-3 fatty acids on leukotriene B4 and leukotriene B5 production by stimulated neutrophils in patients with colorectal cancer: a randomized, placebo-controlled intervention trial.

Omega-3 fatty acids (n-3 FA) may have beneficial clinical and immune-modulating effects in surgical patients. In a randomized, double-blind, prospective, placebo-controlled trial, 148 patients referred for elective colorectal cancer surgery received an n-3 FA-enriched oral nutritional supplement (ONS) providing 2.0 g of eicosapentaenoic acid (EPA) and 1.0 g of docosahexaenoic acid (DHA) per day or a standard ONS for seven days before surgery. On the day of operation, there was a significant increase in the production of leukotriene B5 (LTB5) (p < 0.01) and 5-hydroxyeicosapentaenoic acid (5-HEPE) (p < 0.01), a significant decrease in the production of leukotriene B4 (LTB4) (p < 0.01) and a trend for a decrease in the production of 5-hydroxyeicosatetraenoic acid (5-HETE) (p < 0.1) from stimulated neutrophils in the active group compared with controls. There was no association between LTB4 values and postoperative complications. In conclusion, oral n-3 FA exerts anti-inflammatory effects in surgical patients, without reducing the risk of postoperative complications.

Measuring nutritional risk in hospitals.

About 20%-50% of patients in hospitals are undernourished. The number varies depending on the screening tool amended and clinical setting. A large number of these patients are undernourished when admitted to the hospital, and in most of these patients, undernutrition develops further during hospital stay. The nutrition course of the patient starts by nutritional screening and is linked to the prescription of a nutrition plan and monitoring. The purpose of nutritional screening is to predict the probability of a better or worse outcome due to nutritional factors and whether nutritional treatment is likely to influence this. Most screening tools address four basic questions: recent weight loss, recent food intake, current body mass index, and disease severity. Some screening tools, moreover, include other measurements for predicting the risk of malnutrition. The usefulness of screening methods recommended is based on the aspects of predictive validity, content validity, reliability, and practicability. Various tools are recommended depending on the setting, ie, in the community, in the hospital, and among elderly in institutions. The Nutrition Risk Screening (NRS) 2002 seems to be the best validated screening tool, in terms of predictive validity ie, the clinical outcome improves when patients identified to be at risk are treated. For adult patients in hospital, thus, the NRS 2002 is recommended.
