Aim: To consider the question of whether to initiate trophic feeds with formula in the absence of own mother’s breastmilk or to wait for breastmilk to be available. Methods: A retrospective study of infants born prior to 32 weeks of gestation during the period 2012–2017 at a single tertiary center in Tel Aviv, Israel. Three TF groups were defined: exclusive breastmilk, mixed, and exclusive formula. Univariate and multivariate analyses were conducted. Logistic regression was used, and adjusted odds ratio and 95% interval were reported. Results: Univariate analysis demonstrated that infants in the exclusive breastmilk group were born earlier, had lower birth weights and lower Apgar scores, were given lower volumes of TF, and were more likely to have a longer hospital stay. Poor composite outcome was more common among the exclusive breastmilk group. Multivariate regression analysis revealed no differences in incidence of early neonatal morbidities between the groups, except for longer duration of parenteral nutrition in the exclusive breastmilk group. Conclusion: In our cohort, exclusive formula TF was not associated with increased risk of any of the studied morbidities. Clinicians should consider this finding in deciding between early TF or fasting while waiting for own mother’s breastmilk. 相似文献
The evolution of congenital cardiac surgery has seen significant innovative advances in collaborative efforts between congenital cardiac surgeons and interventionalists to provide the least invasive intervention with the greatest hemodynamic benefit for patients with congenital heart disease. This review looks at how this collaborative approach has evolved and is being applied to treat a number of congenital conditions across the age ranges. 相似文献
Low molecular weight heparins (LMWHs) are a rapidly growing class of anticoagulant drug. Their efficacy has been demonstrated in several clinical settings where they are rapidly becoming the anticoagulant of choice. Controlled clinical studies in patients with deep vein thrombosis, pulmonary embolism, and unstable angina have documented that the frequency of major hemorrhage is 0.5-4%. The purpose of the study was to determine the frequency of minor and major hemorrhage occurring in patients receiving anticoagulant doses of an LMWH (enoxaparin) during routine clinical practice. A prospective, observational study of consecutive patients receiving enoxaparin 1 mg/kg twice daily for at least 24 hours in five internal medicine wards of a university teaching hospital was performed. Five hundred forty-nine patients were studied. The mean age was 67.5+/-15.5 years and the mean duration of enoxaparin therapy was 3.8+/-1.5 days. Hemorrhage was documented in a total of 94 patients (17.3%). Major hemorrhage occurred in 14 patients (2.6%), injection-site hemorrhage occurred in 55 patients (10%), and minor hemorrhage (noninjection site) was documented in 25 patients (4.7%). There were two deaths attributed to hemorrhage. Patients with major hemorrhage were older than patients with minor or no hemorrhage (75.5+/-10.4 versus 66.8+/-15.2 years; p=0.03) and occurred in patients receiving enoxaparin for a longer period (5.14+/-3.8 days) than those with minor (4+/-2.5 days) or no hemorrhage (2.9+/-2.1 days). Major hemorrhage was significantly associated with impaired renal function, chronic liver disease, and concomitant treatment with warfarin or a proton pump inhibitor. Enoxaparin used in anticoagulant doses in unselected medical patients is not associated with more major hemorrhagic complications than observed in controlled clinical trials. Major hemorrhage may be more likely in older patients, in patients with chronic liver disease and impaired renal function, in patients receiving prolonged enoxaparin therapy, and in patients receiving warfarin or proton pump inhibitors. 相似文献
Distinguishing between fibrotic and inflammatory strictures in Crohn’s disease (CD) is still challenging. The capacity of diffusion-weighted (DWI) magnetic resonance (MRE) to identify intestinal fibrosis was recently demonstrated; however, the therapeutic implications of this association have never been evaluated. The aim of the current study was to identify imaging features, including DWI, which can predict response to anti-inflammatory treatment in patients with stricturing CD.
Methods
Consecutive CD patients with intestinal strictures that initiated treatment with anti-tumor necrosis alpha (anti-TNF) between June 2012 and April 2017 with MRE adjacent to treatment onset were retrospectively collected. The primary outcome was treatment failure, defined as drug discontinuation, CD-related surgery, or endoscopic dilatation of the stricture. Clinical, demographic, and imaging data were compared between patients who did and did not develop treatment failure within 12 months of anti-TNF treatment initiation.
Results
A total of 21 patients were included in the study; 9/21 (42.8%) developed treatment failure. None of the clinical/demographic parameters were associated with the risk of treatment failure. Among imaging parameters, only ADC value (< 1 × 10−3 mm2/s) was significantly associated with the risk of treatment failure (AUC = 0.81, 66% vs. 0%, p = 0.015).
Conclusions
Our results suggest that ADC value on DWI MRE may predict the risk of treatment failure in stricturing CD. If replicated in larger studies, these results may guide therapeutic decisions and suggest avoiding anti-TNF treatment.
Inflammatory bowel disease, encompassing Crohn’s disease (CD) and ulcerative colitis, are chronic immune-mediated inflammatory bowel diseases (IBD) that primarily affect the gastrointestinal tract with periods of activity and remission. Large body of evidence exist to strengthen the prognostic role of endoscopic evaluation for both disease activity and severity and it remains the gold standard for the assessment of mucosal healing. Mucosal healing has been associated with improved clinical outcomes with prolonged remission, decreased hospitalization, IBD-related surgeries and colorectal cancer risk. Therefore, endoscopic objectives in IBD have been incorporated as part of standard care. With the known increased risk of colorectal cancer in IBD, although prevention strategies continue to develop, regular surveillance for early detection of neoplasia continue to be paramount in IBD patients’ care. It is thanks to evolving technology and visualization techniques that surveillance strategies are continuously advancing. Therapeutic endoscopic options in IBD have also been expanding, from surgery sparing therapies such as balloon dilation of fibrostenotic strictures in CD to endoscopic mucosal resection of neoplastic lesions. In this review article, we discuss the current evidence on the use of endoscopy as part of standard of care of IBD, its role in surveillance of neoplasia, and the role of interventional endoscopic therapies. 相似文献
A balanced translocation affecting DISC1 cosegregates with several psychiatric disorders, including schizophrenia, in a Scottish family. DISC1 is a hub protein of a network of protein–protein interactions involved in multiple developmental pathways within the brain. Gene set‐based analysis has been proposed as an alternative to individual analysis of single nucleotide polymorphisms (SNPs) to get information from genome‐wide association studies. In this work, we tested for an overrepresentation of the DISC1 interacting proteins within the top results of our ranked list of genes based on our previous genome‐wide association study of missense SNPs in schizophrenia. Our data set consisted of 5100 common missense SNPs genotyped in 476 schizophrenic patients and 447 control subjects from Galicia, NW Spain. We used a modification of the Gene Set Enrichment Analysis adapted for SNPs, as implemented in the GenGen software. The analysis detected an overrepresentation of the DISC1 interacting proteins (permuted P‐value = 0.0158), indicative of the role of this gene set in schizophrenia risk. We identified seven leading‐edge genes, MACF1, UTRN, DST, DISC1, KIF3A, SYNE1, and AKAP9, responsible for the overrepresentation. These genes are involved in neuronal cytoskeleton organization and intracellular transport through the microtubule cytoskeleton, suggesting that these processes may be impaired in schizophrenia. 相似文献

Activating mutations of the interleukin‐7 receptor (IL7R) occur in approximately 10% of patients with T cell acute lymphoblastic leukaemia (T‐ALL). Most mutations generate a cysteine at the transmembrane domain leading to receptor homodimerization through disulfide bond formation and ligand‐independent activation of STAT5. We hypothesized that the reducing agent N‐acetylcysteine (NAC), a well‐tolerated drug used widely in clinical practice to treat acetaminophen overdose, would reduce disulfide bond formation, and inhibit mutant IL7R‐mediated oncogenic signalling. We found that treatment with NAC disrupted IL7R homodimerization in IL7R‐mutant DND‐41 cells as assessed by non‐reducing Western blot, as well as in a luciferase complementation assay. NAC led to STAT5 dephosphorylation and cell apoptosis at clinically achievable concentrations in DND‐41 cells, and Ba/F3 cells transformed by an IL7R‐mutant construct containing a cysteine insertion. The apoptotic effects of NAC could be rescued in part by a constitutively active allele of STAT5. Despite using doses lower than those tolerated in humans, NAC treatment significantly inhibited the progression of human DND‐41 cells engrafted in immunodeficient mice. Thus, targeting leukaemogenic IL7R homodimerization with NAC offers a potentially effective and feasible therapeutic strategy that warrants testing in patients with T‐ALL. 相似文献
