Tolerance and nutritional therapy of dietary fibre from konjac glucomannan hydrolysates for patients with inflammatory bowel disease (IBD)

Carbohydrates may provide an alternative therapeutic approach for a number of digestive health disorders such as inflammatory bowel disease (IBD). The aim of this work was to characterise the tolerance and efficacy of low and high molecular weight konjac glucomannan hydrolysates within healthy volunteers and patients suffering from IBD and associated gut conditions. These conditions included constipation, Crohn's disease and ulcerative colitis. For general tolerance, fourteen patients participated whilst for the digestive disorder trial, there were twenty. Scores of taste/texture of the product, bowel movement, stool consistency, diarrhoea, existence/absence of blood in the faeces, abdominal pains, flatulence, vomiting, fever, improvement of life style after use, willingness to use in the future and clinician's statements about each patient's conditions before and after use were recorded. The results showed that the hydrolysates were tolerated well for patients with diarrhoea and had a significant improvement on bowel movement, stool consistency, abdominal pain and flatulence after ten days. With respect to effects on IBD, there was a significant health benefit after fourteen days of consumption for bowel movement, stool consistency, diarrhoea, existence/absence of blood in the faeces, abdominal pain, flatulence and vomiting. Most patients declared an improvement of their life style after consuming the hydrolysates. The use of konjac glucomannan hydrolysates as a therapeutic agent or adjunct to standard treatments could prove a successful tool for the treatment of a range of disorders; although large scale studies are required to characterise further the role of the carbohydrates.

Dyspeptic symptoms and delayed gastric emptying of solids in patients with inactive Crohn's disease

Background: Patients with Crohn's disease (CD) have been shown to present dyspeptic symptoms more frequently than the general population. Some of these symptoms could be related to motility disorders to some degree. Then, we propose to investigate whether gastric emptying of solids in patients with inactive CD is delayed and to determine the relationships between gastric emptying and dyspeptic symptoms in inactive CD. Methods: Twenty-six patients with inactive Crohn's disease, as defined by a Crohn's Disease Activity Index (CDAI) < 150, underwent a gastric emptying test by breath test using C-13 octanoic acid coupled to a solid meal and answered a validated questionnaire (The Porto Alegre Dyspeptic Symptoms Questionnaire) to assess dyspeptic symptoms. Patients with scores >= 6 were considered to have dyspepsia. The control group was composed by 19 age-and sex-matched healthy volunteers. Results: Patients with CD had a significantly longer t 1/2 and t lag (p<0.05) than the controls. CD patients with dyspepsia had significantly (p<0.05) prolonged gastric emptying when compared to patients without dyspeptic symptoms. When the individual symptom patterns were analyzed, only vomiting was significantly associated with delayed gastric emptying (p<0.05). There was no difference between the subgroups of patients with respect to gender, CDAI scores, disease location, clinical behavior (obstructive/obstructive) or previous gastrointestinal surgery. Conclusion: Delayed gastric emptying in inactive Crohn's disease patients seems to be associated with dyspeptic symptoms, particularly vomiting, even without any evidence of gastrointestinal obstruction.

THE OCCURRENCE OF HEADACHES AND THEIR EFFECT UPON NURSING UNDERGRADUATE STUDENTS

This study was performed with the objectives of identifying the occurrence of headache as the major cause of pain and characterizing the effect headaches have on the everyday activities of nursing undergraduate students. This cross-sectional study was performed at the College of Nursing of the Federal University of Goias, Goiania, Brazil, from May to June 2008. Participants included 203 students (mean age 21 years; s.d.=1.8), 48.5% from economic class A. Headaches were the major cause of pain for 34.5% of students; described as being of strong intensity; referred to as throbbing (74.3%), stabbing (62.9%), and causing nausea and/or vomiting (55.7%); with episodes occurring in the afternoon (52.9%), and lasting for several hours a day (51.4%). Factors related to the onset of pain were: studying (17.1%) and stress (11.4 %). The activities most affected were: their capacity to concentrate (84.3%) and their mood (84.3%) (p < 0.05). Headaches are less common in the population compared to other country studies, and they affect the students' everyday activities.

Wilson's disease: an analysis of 28 Brazilian children

OBJECTIVES: Clinical-laboratory and evolutionary analysis of twenty-eight patients with Wilson's disease. METHODS: Twenty-eight children (twelve females and sixteen males) with Wilson's disease were evaluated retrospectively between 1987 and 2009, with a follow-up of 72 months (1 -240 months). The clinical, laboratory, and histologic features at diagnosis were recorded at the end of the study. RESULTS: The median age at diagnosis was 11 years (2 -18 years). Twelve patients were asymptomatic, seven had hepatitis symptoms, five had raised aminotransferase levels, three had hepatomegaly associated with neurological disorders, one had fulminant hepatitis with hemolytic anemia, and six patients presented with a Kayser-Fleischer ring. A histological analysis revealed that six children had chronic hepatitis, seven had cirrhosis, two had steatosis, one had portal fibrosis, and one had massive necrosis. The treatment consisted of D-penicillamine associated with pyridoxine for 26 patients. Adverse effects were observed in the other two patients: one presented with uncontrollable vomiting and the other demonstrated elastosis perforans serpiginosa. At the end of the study, all 26 treated patients were asymptomatic. Twenty-four of the patients were treated with D-penicillamine and pyridoxine, and two were treated with trientine and zinc sulfate. A liver transplant was performed in one patient with fulminant hepatitis, but the final patient died 48 hours after admission to the intensive care unit. CONCLUSIONS: Family screenings associated with early treatment are important in preventing Wilson's disease symptoms and potentially fatal disease progression. The study suggests that Wilson's disease must be ruled out in children older than two years presenting with abnormal levels of hepatic enzymes because of the heterogeneity of symptoms and the encouraging treatment results obtained so far.

Effects of eating disorders on oral fungal diversity

Background. The eating disorders anorexia and bulimia nervosa can cause several systemic and oral alterations related to poor nutrition and induced vomiting; however, the oral microflora of these patients is poorly studied. Objective. The aim of this study was to evaluate fungal microflora in the oral cavity of these patients by culture-dependent and culture-independent methods. Study Design. Oral rinse samples were cultured to assess the prevalence of Candida species, and the isolates were identified by API system. Microorganism counts were compared by the Mann-Whitney test (5%). Ribotyping, a type of molecular analysis, was performed by sequencing the D1/D2 regions of 28S rRNA. Results. Our results demonstrated that the eating disorder group showed higher oral Candida spp. prevalence with culture-dependent methods and higher species diversity with culture-independent methods. Conclusions. Eating disorders can lead to an increased oral Candida carriage. Culture-independent identification found greater fungal diversity than culture-dependent methods.

Metabolic Improvements in Obese Type 2 Diabetes Subjects Implanted for 1 Year with an Endoscopically Deployed Duodenal-Jejunal Bypass Liner

Background: The purpose of this study was to evaluate the effect of the duodenal-jejunal bypass liner (DJBL), a 60-cm, impermeable fluoropolymer liner anchored in the duodenum to create a duodenal-jejunal bypass, on metabolic parameters in obese subjects with type 2 diabetes. Methods: Twenty-two subjects (mean age, 46.2 +/- 10.5 years) with type 2 diabetes and a body mass index between 40 and 60 kg/m(2) (mean body mass index, 44.8 +/- 7.4 kg/m(2)) were enrolled in this 52-week, prospective, open-label clinical trial. Endoscopic device implantation was performed with the patient under general anesthesia, and the subjects were examined periodically during the next 52 weeks. Primary end points included changes in fasting blood glucose and insulin levels and changes in hemoglobin A1c (HbA1c). The DJBL was removed endoscopically at the end of the study. Results: Thirteen subjects completed the 52-week study, and the mean duration of the implant period for all subjects was 41.9 +/- 3.2 weeks. Reasons for early removal of the device included device migration (n = 3), gastrointestinal bleeding (n = 1), abdominal pain (n = 2), principal investigator request (n = 2), and discovery of an unrelated malignancy (n = 1). Using last observation carried forward, statistically significant reductions in fasting blood glucose (-30.3 +/- 10.2 mg/dL), fasting insulin (-7.3 +/- 2.6 mu U/mL), and HbA1c (-2.1 +/- 0.3%) were observed. At the end of the study, 16 of the 22 subjects had an HbA1c < 7% compared with only one of 22 at baseline. Upper abdominal pain (n = 11), back pain (n = 5), nausea (n = 7), and vomiting (n = 7) were the most common device-related adverse events. Conclusions: The DJBL improves glycemic status in obese subjects with diabetes and therefore represents a nonsurgical, reversible alternative to bariatric surgery.

Influence of Roux-en-Y Gastric Bypass Surgery on Vitamin C, Myeloperoxidase, and Oral Clinical Manifestations: A 2-Year Follow-Up Study

Background: Bariatric surgery influences the intake and absorption of nutrients. The serum concentrations of vitamin C, myeloperoxidase (MPO) and oral clinical manifestations were examined in patients two years after Roux-en-Y gastric bypass (RYGB). Methods: Clinical prospective-study with control-group (CG; n = 26), assessed only once, and the bariatric-group (BG; n = 26), assessed in the basal period and at 12 and 24 months after surgery. The mean ages in the CG and BG were 37.8 +/- 1.51 and 39.6 +/- 1.93 years, respectively, and their body mass indices were 22.07 +/- 0.29 and 45.62 +/- 1.46 kg/m2, respectively. Results: At 12 months after surgery, increased episodes of vomiting (P < .001) and dental hypersensitivity (P=.012) were observed, with a reduction in the saliva buffering capacity of 21.3 2.9% (P=.004). At 24 months after RYGB, we detected a significant reduction in serum vitamin C (32.9 +/- 5.3%, P < .001) and MPO values were higher than in the basal period (P = .032). With regard to oral hygiene habits, 92.3% of patients reported frequent tooth brushing and 96.1% used fluoride, which were similar across the two years. However, dental hypersensitivity (P = .048) was significantly increased than baseline. Conclusions: The results demonstrated that vitamin C deficiency and increased vomiting after RYGB for morbid obesity may contribute to increased periodontal disease. The fact it is impossible to determine which factors (diet, poor compliance with supplementation, vomiting, poor oral hygiene) contributed to the dental problems in these patients is a shortcoming of the report.

Risk factors associated with death in Brazilian children with severe dengue: a case-control study

Objective: The purpose of this case-control study was to evaluate risk factors associated with death in children with severe dengue. Methods: The clinical condition of hospitalized patients with severe dengue who died (cases, n = 18) was compared with that of hospitalized patients with severe dengue who survived (controls, n = 77). The inclusion criteria for this study were age under 13 years; hospital admission in São Luis, northeastern Brazil; and laboratory-confirmed diagnosis of dengue. Results: Severe bleeding (hemoptysis), a defining criterion for dengue severity, was the factor most strongly associated with death in our study. We also found that epistaxis and persistent vomiting, both included as warning signs in the World Health Organization (WHO) classification of dengue, were strongly associated with death. No significant association was observed between any of the laboratory findings and death. Conclusions: The finding that epistaxis and persistent vomiting were also associated with death in children with severe dengue was unexpected and deserves to be explored in future studies. Because intensive care units are often limited in resource-poor settings, any information that can help to distinguish patients with severe dengue with a higher risk to progress to death may be crucial.

Ricerca di Escherichia coli produttori di verocitotossine e definizione di obiettivi di performance nella produzione primaria di alimenti di origine animale

La presenza di Escherichia coli produttori di verocitotossine (VTEC o STEC) rappresenta una tra le più importanti cause di malattia alimentare attualmente presenti in Europa. La sua presenza negli allevamenti di animali destinati alla produzione di alimenti rappresenta un importante rischio per la salute del consumatore. In conseguenza di comuni contaminazioni che si realizzano nel corso della macellazione, della mungitura i VTEC possono essere presenti nelle carni e nel latte e rappresentano un grave rischio se la preparazione per il consumo o i processi di lavorazione non comportano trattamenti in grado d’inattivarli (es. carni crude o poco cotte, latte non pastorizzato, formaggi freschi a latte crudo). La contaminazione dei campi coltivati conseguente alla dispersione di letame o attraverso acque contaminate può veicolare questi stipiti che sono normalmente albergati nell’intestino di ruminanti (domestici e selvatici) e anche prodotti vegetali consumati crudi, succhi e perfino sementi sono stati implicati in gravi episodi di malattia con gravi manifestazioni enteriche e complicazioni in grado di causare quadri patologici gravi e anche la morte. Stipiti di VTEC patogeni ingeriti con gli alimenti possono causare sintomi gastroenterici, con diarrea acquosa o emorragica (nel 50% dei casi), crampi addominali, febbre lieve e in una percentuale più bassa nausea e vomito. In alcuni casi (circa 5-10%) l’infezione gastroenterica si complica con manifestazioni tossiemiche caratterizzate da Sindrome Emolitico Uremica (SEU o HUS) con anemia emolitica, insufficienza renale grave e coinvolgimento neurologico o con una porpora trombotica trombocitopenica. Il tasso di mortalità dei pazienti che presentano l’infezione da E. coli è inferiore all’1%. I dati forniti dall’ECDC sulle infezioni alimentari nel periodo 2006-2010 hanno evidenziato un trend in leggero aumento del numero di infezioni a partire dal 2007. L’obiettivo degli studi condotti è quello di valutare la prevalenza ed il comportamento dei VTEC per una analisi del rischio più approfondita.

Einfluss einer indirekten pharmazeutischen Betreuung auf klinische und soziale Ergebnisse bei ambulant mit Chemotherapie behandelten Tumorpatienten

Krebspatienten, die eine Chemotherapie erhalten, leiden häufig an schwerwiegenden unerwünschten Arzneimittelwirkungen, wie z.B. Übelkeit und Erbrechen, welche nachweislich durch eine geeignete Supportivmedikation und durch eine direkte pharmazeutische Betreuung gesenkt werden können.rnIn dieser Arbeit wurde in einer prospektiven, nicht-interventionellen multizentrischen Studie untersucht, ob ambulant behandelte Mamma- und Colon-Carcinom-Patienten während der Chemotherapie Vorteile durch eine indirekte pharmazeutische Betreuung (Mitgabe einer schriftlichen Patienteninformation und der Begleitmedikamente) haben. Primäres Ziel der Studie war eine Reduktion von Häufigkeit und Schweregrad ausgewählter UAW, sekundäre Ziele waren die Verbesserung der Lebensqualität, der Patientenzufriedenheit und des Patientenwissens zur Therapie und Begleitmedikation. Die Daten wurden mittels vier verschiedener Patienten-Fragebögen in Form von Telefoninterviews zu drei verschiedenen Zeitpunkten der Chemotherapie erhoben.rnInsgesamt konnten 106 Patienten vom St.-Johannes-Hospital in Dortmund und von der Universitätsmedizin Mainz in die Studie eingeschlossen werden. Die UAW nach Häufigkeit und Schweregrad gemäß CTC konnten durch eine indirekte pharmazeutische Betreuung zu allen drei Zeitpunkten der Datenerfassung z.T. signifikant gesenkt werden. Eine Verbesserung konnte auch bei allen humanistischen Ergebnisparametern (Patientenwissen, Lebensqualität, Patientenzufriedenheit) beobachtet werden. Auf Grund der relativ kleinen, nicht vollständig rekrutierten Kontrollgruppe und den unterschiedlichen Rahmenbedingungen an den teilnehmenden Kliniken, sind weitere vergleichende Untersuchungen erforderlich, um den Nutzen einer indirekten pharmazeutischen Betreuung weiter zu belegen. rn
