Introduction: Urinary tract infections (UTIs) are among the most common bacterial infections, affecting 150 million people worldwide each year. Importantly, the incidence of UTI increases markedly with age. The increasing resistance to empirically prescribed antimicrobial agents complicates the management of this disease. This makes UTI an important issue in increasingly aging population and updated epidemiological investigation is advisable. : To understand the epidemiological variation in UTI resistance patterns among differently aged populations, we conducted a retrospective study among patients presenting to the emergency department (ED) of a large tertiary-care hospital in Italy during January 2013 and June 2017. Methods: 1281 patients who presented with UTI symptoms to the ED, were stratified into four age categories: young adults (18-44 years old;), adults (45-64), the elderly (65-84), and the oldest old (≥ 85). Inclusion criteria were urine collected in ED patients with UTI symptoms and first positive culture from one given patient in a given year. Results: 362 (28.2%) patients had a urine culture with positive result, leading to a total of 459 germs isolated, stratified into four categories: young adults (58 isolates, 12.6%), adults (98, 21.4%), the elderly (174, 37.9%), and the oldest old (129, 28.1%). : Escherichia coli represents the 60% of all monomicrobial infections, followed in frequency by Klebsiella pneumoniae (15%), and Enterococcus faecalis (5%). The other 20% of the infections are caused by various germs. : The most common association of germs in polymicrobial is E. coli + E. faecalis, accounting for the 28% of all infections. : Overall, we found a peak of susceptibility to amoxicillin (AMX) in the oldest old ( 81%), significantly higher compared to young adults (54%), adults (47%) and elderly (35%) (p : For ciprofloxacin (CIP) there is a greater susceptibility in the young adult (55.5%), but not so marked compared to the other three groups; for fosfomicin (FOS) the susceptibility was greater in the group of adults (60%) compared to young adults, elderly and the oldest old. Also for trimethoprim/ sulfamethoxazole (TMP-SMX) we found greater susceptibility in the adult group (60%), followed by the oldest old (57,6%), young adults (49%) and elderly (47%). Conclusion: Age-related differences in antimicrobial-resistant microorganisms were evident for adults with UTI, and could potentially contribute to the risk of inappropriate empirical therapy in elderly patients. Thus, different empirical antimicrobial regimens should be considered for distinct age groups.

Background Previous studies showed that troponin blood levels may increase after exercise. In this study we assessed whether, among patients admitted with suspected unstable angina, the increase in high-sensitive troponin T (hs-TnT) levels after exercise stress test (EST) might help identify those with obstructive coronary artery disease (CAD) and predict symptom recurrence during short term follow-up. Methods Maximal treadmill EST was performed in 69 consecutive patients admitted to the emergency room with a suspicion of unstable angina (acute chest pain but confirmed normal serum levels of cardiac troponins) was measured before and 4 hours after EST. Coronary angiography was performed in 22 patients (32.8%). Results hs-TnT increased after EST compared to baseline in the whole population (from 0.84±0.65 to 1.17±0.87 ng/dL, p

Acute uncomplicated diverticulitis (AUD) is an inflammation of the colon diverticulum. We tested the efficacy of Lactobacillus reuteri 4659 (L. reuteri) in treating AUD. Primary outcome was reduced abdominal pain and inflammatory markers (C-RP). Secondary outcome was reduced hours of hospitalization. A double-blind, placebo RCT was conducted with 88 (34M/54F mean age 61.9 ± 13.9) patients with a diagnosis of AUD. Group A (44 patients, 26F): ciprofloxacin 400 mg/bid and metronidazole 500 mg/tid for 1 week, plus L. reuteri/bid for 10 days. Group B (44 patients, 28F): same antibiotic therapy for 1 week, plus placebo/bid for 10 days. All patients completed a daily visual analog scale (VAS) for abdominal pain. Between days 1 and 3, the group A pain decreased by 4.5 points; group B decreased by 2.36 points (p

Acute intramucosal dissection of the esophagus (IED) is a rare complication of eosinophilic esophagitis (EoE). Only few of such IED cases have been described in the literature. We report the case of a 32-year-old man with a 4-months diagnosis of EoE who was referred to the Emergency Department complaining of dysphagia, epigastric pain and fever and who was diagnosed, after an urgent endoscopy, an IED. After careful evaluation and multidisciplinary assessment the patient was managed conservatively, with specific medical therapy—high-dose proton pump inhibitors, swallowed steroid, broad-spectrum antibiotic—and, after a period of absolute fasting, a diet regimen based on “six food elimination diet” with a stepwise increase of food consistency. The patient experienced a rapid and complete relief of symptoms, paralleled by a progressive healing of IED with no recurrence over a 6-month follow-up period. In EoE patients with a high clinical suspicion of an acute IED, we suggest an early execution of chest CT and a contrast esophagography, avoiding potentially dangerous endoscopic procedures in the acute phase that can contribute to enlargement of the dissection, or progression to perforation. Once the diagnosis of IED is confirmed, even in the presence of a contained perforation, a conservative treatment with a multidisciplinary management should always be considered.

Background & aims Diverticular Disease (DD) is a common clinical condition with a dramatic increasing of the prevalence among industrialized countries. Based on the most used classification, DD may be divided into asymptomatic diverticulosis, symptomatic uncomplicated diverticular disease and complicated diverticular disease. Since recent studies pointed out the role of GUT microbiota imbalance in promoting diverticular formation and inflammation, we have designed a systematic review focusing on the possible role of probiotics in the management of this condition. Methods According to PRISMA, we identified studies on DD patients treated with probiotics, by searching on Pubmed, Embase, Cochrane and ResearchGate. Results 13 studies were included in this review based on our selection criteria: 3 double-blind randomized placebo-controlled, 6 open randomized, and 4 non-randomized open studies. Conclusion This is the first systematic review providing an updated measure of evidence on the efficacy of probiotics in a different phase of DD. Even though the majority of studies are still preliminary, current data show a possible clinical application of certain probiotic strains in all stages of DD. Further investigation is then required to better understand when and how probiotics can be used in different phases of DD.

Aims: Subjects with chronic alcohol abuse can present several metabolic and nutritional alterations. The hypothalamic-pituitary-adrenal (HPA) axis may play a role in these nutritional and metabolic disorders. The goal of this study was to investigate if there is any relationship between HP-hormones and metabolic and nutritional parameters in alcoholic subjects. Methods: Sixteen alcoholics were considered before and after 3 months of total alcohol abstinence. HP-related hormones were determined. Nutritional and metabolic parameters were assessed by dual-energy X-ray absorptiometry (DXA) and indirect calorimetry. Results: At baseline, a significant negative correlation was found between fat mass (FM) and cortisol ( r = −0.54, P = 0.03). During abstinence, a significant increase of both body mass index (BMI) ( P < 0.0001) and FM ( P < 0.0001) was found at 12 weeks compared to baseline. A significant decrease of both plasma cortisol ( P = 0.044) and aldosterone ( P = 0.023) was found at 12 weeks compared to baseline. At 12 weeks, the significant correlation between cortisol and FM disappeared. Conclusions: A higher HPA-axis activation—reflected by higher cortisol levels—was associated with a lower FM in alcoholics. Conversely, during total abstinence a reduced HPA-axis activity can play a role in the parallel nutritional recovery. The present results suggest a role of the HPA axis throughout cortisol both in the etiology of the alcohol-related nutritional alterations and in their recovery after a period of total alcohol abstinence.

Background: A relationship between some hypothalamic–pituitary–related hormones and craving for alcohol has been suggested, leading to hypothesize a role of some hormones in the neurobiology of alcohol dependence. Investigating this association in alcohol-dependent (AD) patients was the aim of this preliminary and exploratory study. Methods: Cortisol, adrenocorticotropic hormone, prolactin, thyroid-stimulating hormone (TSH), free T3, free T4, growth hormone, follicle-stimulating hormone, luteinizing hormone as well as administering the Obsessive-Compulsive Drinking Scale (OCDS) and Penn Alcohol Craving Scale (PACS) were assessed at baseline and after 12 weeks in 25 current AD patients. Patients were treated with baclofen (10 mg t.i.d.) for these 12 weeks. Sixteen patients remained totally abstinent for 12 weeks. Results: At baseline, a significant inverse correlation was found between TSH and PACS (r = −0.46; p = 0.022) and OCDS scores (r = −0.53; p = 0.007). A significant direct correlation was found between free T3 and OCDS score (r = 0.44; p = 0.026). In the 16 abstinent patients, craving scores were significantly decreased at 12 weeks (p

SUMMARY Objectives: To evaluate state and trait form of anxiety and current depression in patients affected by gastrointestinal diseases. Methods: We studied 1641 outpatients with gastrointestinal disorders, consecutively referred to our Internal Medicine outpatients from 1997 to 2005. State and trait anxiety were assessed by the State and Trait Anxiety Inventory. Current depression was assessed by the Zung self-rating depression scale. Results: Among patients, 1379 (84.1%) showed state anxiety, 1098 (67%) showed trait anxiety and 442 (27%) showed current depression. The number of gastrointestinal diseases was directly correlated to state anxiety (p < 0.001) and trait anxiety (p = 0.04). Females showed higher levels of anxiety and depression than males (p < 0.001). State anxiety was related to food allergies (p < 0.001), small intestinal bacterial overgrowth (SIBO) (p = 0.001), Hp infection (p = 0.01) and ulcerative colitis in active phase (p = 0.03). Trait anxiety was related to irritable bowel syndrome (IBS) (p < 0.001), Helicobacter pylori (Hp) infection (p = 0.001), food allergies (p = 0.001) and SIBO (p = 0.001). Current depression was related to IBS (p < 0.001) and coeliac disease (p = 0.01), SIBO (p = 0.02). A predicted probability of 0.77 ± 0.16 to have state anxiety, of 0.66 ± 0.12 to have trait anxiety and of 0.39 ± 0.14 to have depression was found in these patients. Conclusions: Most of the patients who seek medical consultation for gastrointestinal problems show an associated affective disorder. These patients should be managed by a team including gastroenterologists, psychologists and ⁄ or psychiatrists, or by a gastroenterologist having expertise in the treatment of psychological disorders. What’s known Anxiety and depression represent a common feature in patients affected by gastrointestinal diseases. These affective disorders can be present as a personality trait or in a reactive form. What’s new The study supports that the approach to patients affected by gastrointestinal diseases should be managed by a team including gastroenterologists, psychologists and ⁄ or psychiatrists, or alternatively they should be managed by gastroenterologist having expertise in the treatment of psychological disorders. 1

Animal studies suggest that the gut-brain peptide ghrelin plays an important role in the neurobiology of alcohol dependence (AD). Human studies show an effect of alcohol on ghrelin levels and a correlation between ghrelin levels and alcohol craving in alcoholics. This investigation consisted of two studies. Study 1 was a 12-week study with alcohol-dependent subjects, where plasma ghrelin determinations were assessed four times (T0-T3) and related to alcohol intake and craving [Penn Alcohol Craving Score (PACS) and Obsessive Compulsive Drinking Scale (OCDS)]. Serum growth hormone levels and assessment of the nutritional/metabolic status were also performed. Study 2 was a pilot case-control study to assess ghrelin gene polymorphisms (Arg51Gln and Leu72Met) in alcohol-dependent individuals. Study 1 showed no significant differences in ghrelin levels in the whole sample, while there was a statistical difference for ghrelin between non-abstinent and abstinent subjects. Baseline ghrelin levels were significantly and positively correlated with the PACS score at T1 and with all craving scores both at T2 and T3 (PACS, OCDS, obsessive and compulsive OCDS subscores). In Study 2, although there was a higher frequency of the Leu72Met ghrelin gene polymorphism in alcohol-dependent individuals, the distribution between healthy controls and alcohol dependent individuals was not statistically significant. This investigation suggests that ghrelin is potentially able to affect alcohol-seeking behaviors, such as alcohol drinking and craving, representing a new potential neuropharmacological target for AD.

OBJECTIVES: Excessive alcohol consumption often results in intestinal damage, mediated by inflammatory processes, mainly characterized by an increased influx of leukocytes. Fecal calprotectin is a granulocyte cytosolic protein, representing as a promising marker of subclinical intestinal inflammation. In this study, we assessed fecal calprotectin concentrations (FCCs) in current drinking alcoholics, both at the baseline, and then during a subsequent 84-day period. Moreover, FCCs in the alcoholics were compared with the FCCs in healthy controls. METHODS: Twenty-eight, active-drinking alcoholics were enrolled in this study and compared with 40 healthy volunteers as the control group. In alcoholics, FCCs were determined at the beginning of the study (baseline; T0) and then every 2 weeks (T1-T6) during the following 84-day period. Potential differences in FCCs were analyzed between alcoholics and healthy controls, and during the 84-day period within the group of alcoholics. In addition, an analysis of FCCs was conducted in three subgroups of alcoholics, considering their drinking status during the 84-day period (abstinent, relapsed, and active). RESULTS: At baseline, no significant differences in median FCCs were found between alcoholics and controls. No significant changes of median FCCs were found, comparing baseline FCCs and FCCs during the 84-day period (T1-T6) in the whole group of alcoholics, nor in the three subgroups of alcoholics. CONCLUSION: FCCs in active-drinking alcoholics are not significantly different, compared with the healthy controls. Moreover, FCCs do not significantly differ according to the alcohol drinking status. These results may suggest the absence of a subclinal intestinal inflammation involving neutrophils in the alcoholics.

The effects of chronic abuse of alcohol and/or other substances of abuse vary considerably, depending, for example, on the concentration and dose. Furthermore, other factors also may play a role, such as nutritional status, gender, and ethnicity. This chapter analyzes the main medical consequences related to substance abuse, namely alcohol, nicotine, opioids, cocaine, amphetamine, and benzodiazepines. The effects of these substances on the liver, gut, pancreas, nervous system, cardiovascular system, and endocrine system are analyzed and discussed. The link between substance abuse disorders and tumors is also reported, as well as the relationship between substances of abuse and nutrition and body composition.

Treating alcohol use disorders represents a main goal in public health, but the effect of current medications is modest. Thus, in the last few years, research has been focusing on identifying new neuropharmacological targets for alcohol dependence. This review will summarize recent research, which has identified new targets to treat alcohol dependence. A variety of systems have been investigated, such as the endocannabinoid system, modulators of glutamatergic transmission, corticotropin-releasing factor (CRF), neuropeptide Y (NPY), nociceptin, glial cell line-derived neurotrophic factor (GDNF), acetaldehyde (ACD), substance P and Neurokinin 1 (NK1) receptor, nicotinic acetylcholine receptors (nAchRs), alpha-adrenergic receptor, and many others. Compared to preclinical studies, only a few clinical studies have been conducted so far. Thus, there is a critical need to translate successful preclinical results into human clinical trials. However, since some clinical studies have failed to replicate preclinical findings, future research will have not only to identify more efficacious medications, but also delineate the best match between a particular pharmacotherapy with a specific alcoholic subtype.

Alcoholism and stress share some common neurobiological circuits, including the GABAergic system. In particular, the GABA(B) receptor seems to play an important role. The GABA(B) receptor agonist baclofen has been studied as a treatment for alcohol-dependent subjects. Baclofen administration in alcohol-dependent patients was able to promote abstinence, inducing the remission of withdrawal symptoms, reducing alcohol craving, and reducing alcohol intake. Baclofen also reduced anxiety in alcohol-dependent subjects, probably acting on brain stress circuitry and/or on other neuroendocrine systems. Baclofen also showed excellent safety and tolerability, even in alcohol-dependent patients with advanced liver disease (i.e., cirrhosis). Future studies should investigate which alcoholic subtype may better benefit of the administration of baclofen in the treatment of alcohol dependence.

Several skin manifestations were described in patients affected by intestinal disorders. The development of skin diseases in these patients could be related to the impairment of intestinal absorption and motility, other than to immunological and hormonal changes. The growing evidence of the association between skin disorders and intestinal diseases suggests that the skin could be considered the ‘mirror of the gut’.

Both animal and human studies suggest that volume-regulating hormones could play a role in alcohol dependence as well as in alcohol craving. The role of the volume-regulating hormones, renin, aldosterone, and the N-terminal pro B-type natriuretic peptide (NT-proBNP) in alcohol craving was therefore evaluated in the present study. Twenty-five actively drinking alcohol-dependent patients satisfied the inclusion criteria and were enrolled into the study. The volume-regulating hormones, renin, aldosterone, and the NT-proBNP, and craving measurements—Obsessive-Compulsive Drinking Scale (OCDS) and Penn Alcohol Craving Scale (PACS)—were performed at baseline and after 12 weeks. Sixteen patients remained totally abstinent for the entire 12 weeks and were available for the second assessments. At baseline, no correlations between hormones and craving scores were found with either the 25 patients initially enrolled or the 16 abstinent patients. At 12 weeks, a significant increase of renin and a significant decrease of aldosterone were observed. Aldosterone showed a significant direct correlation with the obsessive OCDS subscore ( r =0.59, P =.016) and a trend toward a significant direct correlation with the PACS score ( r =0.48, P =.057). Renin demonstrated a significant direct correlation with the obsessive OCDS subscore ( r =0.51, P =.041) and with the PACS score ( r =0.56, P =.025). The NT-proBNP never correlated with craving measurements. In conclusion, the renin-aldosterone axis could play a role in craving in medium-term abstinent patients and thereby leading to the hypothesis that alcohol craving could be influenced by the fluid volume intake.

OBJECTIVE: A high prevalence of anxiety and depression has been reported in coeliac disease (CD). Although social phobia is included among the anxiety disorders, its presence in CD has never been investigated. The aim of the present study was to evaluate social phobia in CD patients. MATERIAL AND METHODS: A total of 40 CD patients were consecutively enrolled in the study. Fifty healthy subjects were studied as controls. Social phobia was assessed by the Liebowitz Social Anxiety Scale (LSAS) and current depression by the modified version of the Zung Self-rating Depression Scale (M-SDS). RESULTS: The percentage of subjects with social phobia was significantly higher in CD patients than in controls (70% versus 16%; p

Several extraintestinal clinical manifestations have been reported in celiac disease (CD). Among them, growing evidence suggests the association between CD and affective and psychiatric disorders. In this review the most frequent affective and psychiatric disorders associated with CD and the possible mechanisms involved in these associations were analyzed. The available data suggest that screening for CD in patients with affective and/or psychiatric symptoms may be useful since these disorders could be the expression of an organic disease rather than primary psychiatric illnesses.

Summary Background Intervention to achieve alcohol abstinence represents the most effective treatment for alcohol-dependent patients with liver cirrhosis; however, anticraving drugs might worsen liver disease. We aimed to investigate the effectiveness and safety of baclofen in achieving and maintaining alcohol abstinence in patients with liver cirrhosis. Methods Between October, 2003, and November, 2006, 148 alcohol-dependent patients with liver cirrhosis were referred to the Institute of Internal Medicine, Rome, Italy. 84 were randomly allocated either oral baclofen or placebo for 12 weeks. Primary outcome was proportion of patients achieving and maintaining alcohol abstinence. Measures of this outcome were total alcohol abstinence and cumulative abstinence duration, which were assessed at outpatient visits. Relapse was defined as alcohol intake of more than four drinks per day or overall consumption of 14 or more drinks per week over a period of at least 4 weeks. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00525252. Findings Of 42 patients allocated baclofen, 30 (71%) achieved and maintained abstinence compared with 12 (29%) of 42 assigned placebo (odds ratio 6·3 [95% CI 2·4–16·1]; p=0·0001). The number of dropouts (termination of treatment) did not differ between the baclofen (6/42 [14%]) and placebo (13/42 [31%]) groups (p=0·12). Cumulative abstinence duration was about twofold higher in patients allocated baclofen than in those assigned placebo (mean 62·8 [SE 5·4] vs 30·8 [5·5] days; p=0·001). No hepatic side-effects were recorded. Interpretation Baclofen is effective at promoting alcohol abstinence in alcohol-dependent patients with liver cirrhosis. The drug is well tolerated and could have an important role in treatment of these individuals.

Background: Ghrelin is a peptide produced mainly by the gut and hypothalamus. Ghrelin is able to stimulate food-seeking behavior. Alcohol-craving and food-seeking behavior could share common neural circuits. Ghrelin is related to nutritional status, but few data are available in alcoholic patients on the relationship between ghrelin and nutritional disorders. Methods: Plasma ghrelin was evaluated in 15 current alcoholic male patients compared with 15 healthy male volunteers. Craving was evaluated by the Obsessive–Compulsive Drinking Scale. Body composition was assessed by dual-energy X-ray absorptiometry. Energy substrate utilization was evaluated by indirect calorimetry. Results: Ghrelin was significantly reduced in alcohol-dependent patients with respect to healthy subjects (p=0.0278). A significant positive correlation was found between ghrelin and craving (r=0.55; p=0.034). A preferential utilization of lipids as an energy substrate with a reduction of the fat mass (p=0.01) and an increase of the free fat mass (p=0.0091) was found in alcoholic patients. Conclusions: Within our sample showing low ghrelin levels probably related to the impaired nutritional status; patients with higher levels of ghrelin showed higher levels of alcohol craving. These preliminary data indicate that ghrelin could be implicated in the neurobiological mechanisms of alcohol craving, other than a hormone influenced by the nutritional status.
