Current guidelines for the treatment of heart failure with reduced ejection fraction (HFrEF) are based on studies that have excluded or underrepresented older patients.To assess the value of guideline directed medical therapy (GDMT) in HFrEF patients 80 years of age and older.A single-center retrospective study included patients hospitalized with a first and primary diagnosis of acute decompensated heart failure (ADHF) and ejection fraction (EF) of ≤ 40%. Patients 80 years of age and older were stratified into two groups: GDMT, defined as treatment at hospital discharge with at least two drugs of the following groups: beta-blockers, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), or mineralocorticoid antagonists; and a personalized medicine group, which included patients who were treated with up to one of these drug groups. The primary outcomes were 90-day all-cause mortality, 90-day rehospitalization, and 3-years mortality.The study included 1152 patients with HFrEF. 254 (22%) patients who were at least 80 years old. Of the group, 123 were GDMT at discharge. When GDMT group was compared to the personalized medicine group, there were no statistically significant differences in terms 90-day mortality (17% vs. 13%, P = 0.169), 90-day readmission (51 % vs. 45.6%, P = 0.27), or 3-year mortality (64.5% vs. 63.3%, P = 0.915).Adherence to guidelines in the older adult population may not have the same effect as in younger patients who were studied in the randomized clinical trials. Larger prospective studies are needed to further address this issue.

Fluoroquinolone prophylaxis during allogeneic hematopoietic stem cell transplantation (allo-HSCT) reduces bloodstream infections. However, this practice affects the gut microbiome and potentially increases dysbiosis, which is closely related to transplantation outcomes, and lower gastrointestinal (GI) tract acute graft-versus-host disease (GVHD). This study assessed the impact of omitting ciprofloxacin prophylaxis on GI GVHD, clinical outcomes, and microbiome composition in patients undergoing allo-HSCT. In this single-center, retrospective study comprising recipients of allo-HSCT performed between 2018 and 2020, routine ciprofloxacin prophylaxis (the exposure variable) was stopped in December 2018. The primary outcome was acute lower GI GVHD within 100 days post-transplantation; secondary outcomes were 1-year overall survival, nonrelapse mortality, relapse, and overall acute GVHD. Outcomes were compared using univariate and multivariate analyses and Kaplan-Meier/competing-risk analyses. Sequential stool samples were collected prospectively from a subpopulation of recipients, and the microbiome composition was analyzed. Seventy-five of the 129 patients (58.1%) received prophylactic ciprofloxacin treatment. Baseline characteristics did not differ between the 2 study groups: patients with ciprofloxacin prophylaxis and those without ciprofloxacin prophylaxis. The rate of lower GI GVHD also did not differ between the 2 groups (24% versus 18.5%; P = .597). None of the secondary outcomes was significantly different between the 2 groups in univariate, multivariate, and time-to-event analyses. In addition, microbiome analysis in a subpopulation of 22 patients did not reveal any significant between-group difference in alpha or beta diversity. Omitting prophylactic ciprofloxacin during allo-HSCT did not affect microbiome composition, lower GI-GVHD rate, or other significant clinical outcomes. The use of prophylactic antibiotics in this setting should be evaluated further.

Inflammatory bowel diseases are associated with various immune- and non-immune-mediated conditions. We aimed to assess the association of inflammatory bowel diseases with comorbidities at late adolescence. Jewish Israeli adolescents who underwent a general health evaluation prior to enlistment to the Israeli Defense Forces from 2002 to 2016 were included. Overall, 891 subjects (595 Crohn’s disease, 296 ulcerative colitis, median age 17.1 years) and 1,141,841 controls were analyzed. Crohn’s disease was associated with arthritis (odds ratio (OR) 4.7, 95% confidence interval (CI) 2.4–9.1), thyroid disease (OR 2.6, 95% CI 1.2–5.5), atopic dermatitis (OR 2, 95% CI 1.1–3.6), autoimmune hepatitis (OR 4.4, 95% CI 2.3–8.6), nephrolithiasis (OR 3.6, 95% CI 1.2–11.4), and pancreatitis (OR 41.8, 95% CI 17.2–101.9). Ulcerative colitis was associated with arthritis (OR 3.6, 95% CI 1.0–9.8), thyroid disease (OR 4.8, 95% CI 1.2–19.4), autoimmune hepatitis (OR 8, 95% CI 4–16.2), and pancreatitis (OR 51, 95% CI 16.1–158.9). Primary sclerosing cholangitis was associated with both diseases. Asthma, celiac, type 1 diabetes, psoriasis, and bone fractures were not more common in both diseases. Male predominance was noted for most associations. At adolescence, both Crohn’s disease and ulcerative colitis are associated with multiple comorbidities, not limited to autoimmune disorders.

BackgroundViral culture is currently the most accurate method to demonstrate viability and infectivity of Severe acute respiratory syndrome Coronavirus (SARS-2 CoV). Routine clinical diagnosis, however, is mostly performed by PCR – based assays that do not discriminate between infectious and non-virus. Herein, we aimed to determine the correlation between positive viral cultures and either PCR positivity, the Cycle Threshold (Ct) or the number of viral copies.MethodsA systematic electronic literature search was performed and studies that reported both viral SARS-CoV-2 culture and PCR–based assays were included. A separate search for samples from blood, urine, stool, breast milk and tears were performed. To convert Ct values reported in the reviewed studies were to viral genomic copies, calibration experiments with four different reaction performed, using quantified RNA molecules.ResultsA total 540 articles were reviewed, and 38 studies were included in this review. Out of 276 positive-culture of non-severe patients, 272 (98.55%) were negative ten days after symptoms onset, while PCR assays remained positive for up to 67 days. In severely ill or immunocompromised patients positive-culture was obtained up to 32 days and out of 168 cultures, 31 (18.45%) stayed positive after day 10. In non-severe patients, in Ct value greater than 30 only 10.8% were still culture-positive while in Ct >35 it was nearly universally negative. The minimal calculated number of viral genome copies in culture-positive sample was 2.5 × 103 copies / mL. These findings were similar in immunocompromised patients. Recovering positive culture from non-respiratory samples was sporadically obtained in stool or urine samples. Conversion of Ct values to viral genome copies showed variability between different PCR assays and highlighted the need to standardize reports to correctly compare results obtained in different laboratories.ConclusionDuring the pandemic phase, non-severe COVID-19 patients who are recovering and are not immuno-suppressed, can be regarded as non-infectious, within 10 days from symptom onset, or with Ct value greater than 35 (or a calculated viral load lower than 1.2×103 copies / mL). These findings have important implications for recovering patients and asymptomatic patients, with respect to isolation criteria. The conversion of Cq values to viral genome copies described herein may be useful in future work, enabling a more standardized comparison between results reported in different studies from different laboratories.

BACKGROUND The incidence and prevalence trends of inflammatory bowel disease (IBD) vary between developed and developing countries. AIM To investigate the prevalence and associated sociodemographic factors of IBD in Israeli Jewish adolescents METHODS: The files of the army medical corps were reviewed for adolescents recruited in 2002-2016 with confirmed IBD. Covariate data included birth date, patient and parental country of birth, number of children in the household, age at diagnosis, and socioeconomic status. Findings were compared with the remaining recruits without IBD. RESULTS Of the 1,144,213 adolescents recruited, 2372 (0.2%) had IBD (Crohn's disease, 68%). Median age of the cohort was 17.1 years (interquartile range, 16.9-17.3). Over the study period, the annual point prevalence per 100,000 examinees significantly increased: total IBD, 58 to 373; Crohn's disease, 42 to 425; ulcerative colitis, 16 to 128. Mean age at IBD diagnosis decreased from 15.0 ± 2.8 years in 2002-2008 to 14.3 ± 3.1 years in 2009-2016 (P

BACKGROUND Growth impairment is common in pediatric inflammatory bowel disease (IBD) patients. Nevertheless, a controversy exists regarding disease impact on anthropometric measures in the long term. Thus, we aimed to investigate the impact of IBD on anthropometric measures, including weight, height, and body mass index (BMI), during late adolescence in a cross-sectional, population-based study. METHODS A total of 1,144,213 Jewish Israeli adolescents who underwent a general health examination from 2002 to 2016 at a median age (interquartile range) of 17.1 (16.9-17.3) years were included. Inflammatory bowel disease cases were stratified into Crohn's disease (CD) and ulcerative colitis (UC). Patients were also subgrouped based on age at IBD diagnosis. RESULTS Overall, 2372 cases of IBD were identified out of 1,144,213 persons examined (0.2%). Crohn's disease accounted for 68% of IBD cases. Males and females with CD (but not with UC) had significantly lower weight and BMI compared with controls. Differences in height at late adolescence were not statistically significant for either disease compared with controls (females: 162 cm vs 161.7 cm vs 161.5 cm; males: 174 cm vs 173.7 cm vs 173.6 cm for controls, UC, and CD, respectively). In a subgroup analysis, patients with CD diagnosed at age

The increase in abdominal volume is slow, progressive and late noticed in some cases, mingling with ascites in about 18-20%. There are few reports of malignant mesenteric cysts, usually low-grade sarcomas. Kurtz et al. reviewed 162 cases and found only 3% of malignant transformation, all in adults. Are incidental findings during laparotomy or imaging, up to 40 % of cases. Acute abdomen occurs when there is rupture, infection, bleeding or twisting of the cyst, and confused with appendicitis or aortic aneurysm. Laboratory tests little help the diagnosis. Simple X-rays of the abdomen may show calcifications; arteriography and intestinal transit may show compressive mass. However, ultrasonography, computed tomography computed and magnetic resonance imaging are the exams that provide better diagnosis. Once diagnosed, all mesenteric cyst should be resected in order to avoid their complications 2-11 , recurrence, malignant transformation and possible complications (hemorrhage, torsion, obstruction, traumatic rupture and infection) 8-12 . Internal drainage may be an option when there is possibility of short bowel syndrome. In selected cases laparoscopic approach can be used 13-15 . Santana et al. 11 classified them as pathologically serous, bloodserous, chylous, with blood. In this case hydatid cist was also placed on judgment in the differential diagnosis, before the end of lymphangioma.

Hypereosinophilic syndrome represents a heterogeneous group of disorders with the common feature of prolonged eosinophilia of unknown cause and organ system dysfunction including the pulmonary system. Hypereosinophilic syndrome, with and without pulmonary involvement, in association with pregnancy is very rare, and to the best of our knowledge only one case of hypereosinophilic syndrome with pulmonary involvement during pregnancy has been previously reported in the medical literature. We describe a case of a patient with previously symptomatic hypereosinophilic syndrome with pulmonary involvement who experienced exacerbations of her disease during two consecutive pregnancies. To the best of our knowledge this is the first report which demonstrates a worsening effect of pregnancy on both eosinophil count and end organ involvement in a patient with previous diagnosis of hypereosinophilic syndrome.
