SUMMARYBackground: Small intestinal bacterial overgrowth and sugar malabsorption (lactose, fructose, sorbitol) may play a role in irritable bowel syndrome. The lactulose breath test is a reliable and non-invasive test for the diagnosis of small intestinal bacterial overgrowth. The lactose, fructose and sorbitol hydrogen breath tests are widely used to detect specific sugar malabsorption. Aim: To assess the extent to which small intestinal bacterial overgrowth may influence the results of hydrogen sugar breath tests in irritable bowel syndrome patients. Methods: We enrolled 98 consecutive irritable bowel syndrome patients. All subjects underwent hydrogen lactulose, lactose, fructose and sorbitol hydrogen breath tests. Small intestinal bacterial overgrowth patients were treated with 1-week course of antibiotics. All tests were repeated 1 month after the end of therapy.

For survivors of severe COVID-19 disease, having defeated the virus is just the beginning of an uncharted recovery path. What follows after the acute phase of SARS-CoV-2 infection depends on the extension and severity of viral attacks in different cell types and organs. Despite the ridiculously large number of papers that have flooded scientific journals and preprinthosting websites, a clear clinical picture of COVID-19 aftermath is vague at best. Without larger prospective observational studies that are only now being started, clinicians can retrieve information just from case reports and or small studies. This is the time to understand how COVID-19 goes forward and what consequences survivors may expect to experience. To this aim, a multidisciplinary post-acute care service involving several specialists has been established at the Fondazione Policlinico Universitario A. Gemelli IRCSS (Rome, Italy). Although COVID-19 is an infectious disease primarily affecting the lung, its multi-organ involvement requires an interdisciplinary approach encompassing virtually all branches of internal medicine and geriatrics. In particular, during the post-acute phase, the geriatrician may serve as the case manager of a multidisciplinary team. The aim of this article is to describe the importance of the interdisciplinary approach-coordinated by geriatrician-to cope the potential post-acute care needs of recovered COVID-19 patients.

SUMMARYBackground: Studies assessing the prevalence of small intestinal bacterial overgrowth in irritable bowel syndrome gave contrasting results. Differences in criteria to define irritable bowel syndrome patients and methods to assess small intestinal bacterial overgrowth may explain different results. Moreover, no data exist on small intestinal bacterial overgrowth prevalence in a significant population of healthy non-irritable bowel syndrome subjects. Aim: To assess the prevalence of small intestinal bacterial overgrowth by glucose breath test in patients with irritable bowel syndrome symptoms with respect to a consistent control group. Methods: Consecutive patients with irritable bowel syndrome according to Rome II criteria were enrolled. The control population consisted of 102 sex-and age-matched healthy subjects without irritable bowel

Background A remarkably high incidence of venous thromboembolism (VTE) has been reported among critically ill patients with COVID‐19 assisted in the intensive care unit (ICU). However, VTE burden among non‐ICU patients hospitalized for COVID‐19 that receive guideline‐recommended thromboprophylaxis is unknown. Objectives To determine the incidence of VTE among non‐ICU patients hospitalized for COVID‐19 that receive pharmacological thromboprophylaxis. Methods We performed a systematic screening for the diagnosis of deep vein thrombosis (DVT) by lower limb vein compression ultrasonography (CUS) in consecutive non‐ICU patients hospitalized for COVID‐19, independent of the presence of signs or symptoms of DVT. All patients were receiving pharmacological thromboprophylaxis with either enoxaparin or fondaparinux. Results The population that we screened consisted of 84 consecutive patients, with a mean age of 67.6 ± 13.5 years and a mean Padua Prediction Score of 5.1 ± 1.6. Seventy‐two patients (85.7%) had respiratory insufficiency, required oxygen supplementation, and had reduced mobility or were bedridden. In this cohort, we found 10 cases of DVT, with an incidence of 11.9% (95% confidence interval [CI] 4.98‐18.82). Of these, 2 were proximal DVT (incidence rate 2.4%, 95% CI −0.87‐5.67) and 8 were distal DVT (incidence rate 9.5%, 95% CI 3.23‐5.77). Significant differences between subjects with and without DVT were D‐dimer > 3000 µg/L (P < .05), current or previous cancer (P < .05), and need of high flow nasal oxygen therapy and/or non‐invasive ventilation (P < .01). Conclusions DVT may occur among non‐ICU patients hospitalized for COVID‐19, despite guideline‐recommended thromboprophylaxis.

SUMMARYBackground: Patients with inflammatory bowel disease have an increased risk of thrombotic complications; moreover, mesenteric microvascular thrombosis has been hypothesized as a contributing factor in the pathogenesis of inflammatory bowel disease. Aim: To assess the extent of subclinical atherosclerosis in inflammatory bowel disease by measuring the intima-media thickness of the common carotid artery. Methods: Fifty-two patients were enrolled in the study. Patients aged >45 years, with a history of cardiovascular disease and known risk factors for atherosclerosis were excluded from the study. Twenty healthy subjects were studied as controls. Carotid ultrasonography was performed in all patients and controls. intima-media thickness was measured proximal to the carotid bifurcation

SUMMARYBackground: Few controlled studies assessing choice and duration of antibiotic therapy for small intestinal bacterial overgrowth are available. Aim: To assess efficacy, safety and tolerability of different doses of rifaximin, a broad spectrum non-absorbable antibiotic, for intestinal bacterial overgrowth eradication. Methods: We enrolled 90 consecutive patients affected by small intestinal bacterial overgrowth. The presence of small intestinal bacterial overgrowth was based on the occurrence of a rise of H 2 values >12 p.p.m. above the basal value after 50 g glucose ingestion. Patients were randomized in three 7-day treatment groups:

Peripheral artery disease (PAD) is one of the most relevant complications of diabetes. Although several pharmacological and revascularization approaches are available for treating patients with diabetes and PAD, an endovascular approach is often associated with postprocedural complications that can increase the risk for acute limb ischemia or amputation. However, no definitive molecular associations have been described that could explain the difference in outcomes after endovascular treatment in patients with diabetes, PAD, and chronic limb-threatening ischemia (CLTI). RESEARCH DESIGN AND METHODSWe evaluated the relationship between the levels of the main cytokines associated with diabetic atherosclerosis and the outcomes after endovascular procedures in patients with diabetes, PAD, and CLTI. RESULTSA total of 299 patients with below-the-knee occlusive disease who were undergoing an angioplasty procedure were enrolled. The levels of key cytokinesdosteoprotegerin (OPG), tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), and C-reactive protein (CRP)dwere measured, and major adverse limb events (MALE) and major adverse cardiovascular events (MACE) were assessed 1, 3, 6, and 12 months after the procedure. There was a linear trend from the lowest to the highest quartile for each cytokine at baseline and incident MALE. A linear association was also observed between increasing levels of each cytokine and incident MACE. Receiver operating characteristics models were constructed using clinical and laboratory risk factors, and the inclusion of cytokines significantly improved the prediction of incident events.
