Background Pathogenesis of acute diverticulitis and diverticular bleeding remains poorly defined, and few data compare directly risk factors for these complications. Aims to assess differences in clinical features, lifestyles factors and concurrent drug use in patients with acute diverticulitis and those with diverticular bleeding. Methods Data were obtained from the REMAD Registry, an ongoing 5-year prospective, observational, multicenter, cohort study conducted on 1,217 patients. Patient- and clinical- related factors were compared among patients with uncomplicated diverticular disease, patients with previous acute diverticulitis, and patients with previous diverticular bleeding. Results Age was significantly lower (OR 0.48, 95% CI: 0.34–0.67) and family history of diverticular disease was significantly higher (OR 1.60, 95% CI: 1.11–2.31) in patients with previous diverticulitis than in patients with uncomplicated diverticular disease, respectively. Chronic obstructive pulmonary disease was significantly higher in patients with previous diverticular bleeding as compared with both uncomplicated diverticular disease (OR 8.37, 95% CI: 2.60–27.0) and diverticulitis (OR 4.23, 95% CI: 1.11–16.1). Conclusion This ancillary study from a nationwide Registry showed that some distinctive features identify patients with acute diverticulitis and diverticular bleeding. These information might improve the assessment of risk factors for diverticular complications.

There are no evidence-based recommendations for performing upper gastrointestinal endoscopy (UGIE) in patients with extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD). However, UGIEs are often performed in clinical practice in these patients. We aimed to assess the prevalence of gastro-oesophageal lesions in patients with atypical GORD symptoms.Patients complaining of at least one extra-oesophageal GORD symptom and undergoing UGIE in seven centres were prospectively enrolled. Clinically relevant lesions (Barrett's oesophagus, erosive oesophagitis, gastric precancerous conditions, peptic ulcer, cancer, andTwo hundred eleven patients were enrolled (male/female: 74/137; mean age: 55.5 ± 14.7 years). Barrett's oesophagus was detected in 4 (1.9%), erosive oesophagitis in 12 (5.7%), gastric precancerous conditions in 22 (10.4%), andClinically relevant lesions are uncommon among young (≤50 years) patients with extra-oesophageal GORD symptoms. Hiatal hernia is not more prevalent in patients with cardiologic symptoms and suspicion of GORD. The usefulness of UGIE in these patients is questionable.Não existem recomendações baseadas na evidencia para realização de endoscopia digestiva alta (EDA) em doentes com sintomas extra-esofágicos da doença de refluxo gastroesofágico (DRGE). No entanto, EDAs são frequentemente realizadas na orientação clínica destes doentes. O nosso objectivo foi a valiar a prevalência de lesões gastro-esofágicas em doentes com sintomas atípicos de DRGE.Doentes com pelo menos um sintoma extra-esofágico de DRGE e que realizaram EDA em 7 centros foram prospectivamente recrutados. Lesões clinicamente relevantes (esófago de Barrett, esofagite erosiva, condições pré-malignas gástricas, úlcera péptica, cancro e infecção H. pylori) foram estatisticamente comparadas entre os grupos tendo em conta sintomas de DRGE (atípicos vs. quer típicos e atípicos), tipo de sintomas atípicos, idade e presenta de hérnia do hiato.Duzentos e onze doentes foram recrutados (H/M: 74/137; Idade média: 55.5 ± 14.7 anos). Esófago de Barrett foi detetado em 4 (1.9%), esofagite erosiva em 12 (5.7%), condições pré-malignas gástricas em 22 (10.4%) e infeção H. pylori em 38 (18%) doentes. A prevalência de lesões clinicamente relevantes foi inferior em doentes com apenas sintomas atípicos (28.6 vs. 42,5%; p = 0.046; teste de qui-quadrado), doentes com50 anos (20 vs. 44.8%; p = 0.004; teste de qui-quadrado), e nos doentes medicados com iniciadores da bomba de protões (IBP) (21.1 vs.40.2%; p = 0.01; teste de qui-quadrado). Nenhuma lesáo clinicamente relevante foi detectada nos doentes com50 anos, sem sintomas de alarme e medicados com IBP. Hérnia do hiato foi diagnosticada apenas em 6 doentes com sintomas do tipo cardíaco e em 41 com sintomas ORLs (11.3 vs. 35.1%; p = 0.03; teste de qui-quadrado).Lesões clinicamente relevantes são incomuns em doentes jovens com sintomas extra-esofágicos de DRGE. Hérnia do hiato não é mais prevalente em doentes com sintomas do tipo cardíaco e suspeita de DRGE. A utilidade da EDA nestes doentes é discutível.

The therapeutic use of biological agents such as anti tumor necrosis factor-alpha drugs carries on an increased risk of reactivation of bacterial infections. Among these, listeriosis is a particularly dreadful infection in that may be associated with septic complications such as meningitis and encephalitis and a relatively high mortality rate. This article will discuss listeria infections in patients treated with biological agents.

The association between gluten related disorders and psychiatric diseases has been firmly demonstrated. Non-celiac gluten sensitivity (NCGS) is a syndrome diagnosed in patients responsive to gluten-free diet after ruling out celiac disease and wheat allergy. The pathogenesis of neuro-psychiatric disorders in NCGS is unclear. An association between gluten and schizophrenia was described for the first time in 1950 by Bender et al. In the 1950's, Dicke noted that gluten-free diet improved mood in celiac patients. In 1970, Goldberg et al., in a study of 80 celiac patients, found that 34% of them showed minor affective disorders. Bipolar disorder patients show an increase of blood anti gliadin deamidated antibodies (IgG). The effect of diet and nutrition on autistic spectrum disorders has been investigated in the last two decades, particularly focusing on the symptoms of hyperactivity and attention. Toxoplasma gondii and other neurotropic pathogens as Influenzavirus and Coronavirus may be associated with mood disorders, probably secondary to an increased intestinal permeability. Abnormalities of host-microbiota interactions or of gut-microbiota composition have been associated with central nervous system disorders, such as autism, anxiety, depression and the integrity of intestinal microbiota may be considered a potential therapeutic goal to treat these conditions.
