Effectiveness of Osteopathic Manipulative Treatment in Adults with Irritable Bowel Syndrome: A Systematic Review and Meta-Analysis.

The aim of this systematic review and meta-analysis was to evaluate the effectiveness of the osteopathic manipulative treatment (OMT) in adults with irritable bowel syndrome (IBS). A literature resview was carried out on the following databases: PubMed, Embase, Cochrane, Cinahl, Scopus, PEDro and ClinicalTrials.gov. 350 articles were recovered. Eligibility criteria were evaluated by two independent reviewers, including randomized controlled trials (RCTs), quasi-RCTs, or ongoing RCTs with OMT compared to any kind of control in patients diagnosed with IBS. Six studies (five RCTs and one ongoing RCT) were considered eligible. Four RCTs were classified as some concerns and one as high risk of bias. In the meta-analysis, OMT compared to sham/no intervention showed statistically significant results for abdominal pain (effect size ES = -1.14 [-1.66, -0.62]; p < 0.0001) and constipation (ES = -0.66 [-1.12, -0.20]; p = 0.005). Instead, OMT was not superior to the control for the IBS symptoms measured with the IBS Severity Score and the Likert scale (ES = -0.34 [-0.83, 0.16]; p = 0.19), and diarrhea (ES = -1.20 [-2.84, 0.43]; p = 0.15). The quality of evidence was "low" for IBS symptoms in general for abdominal pain and constipation, while it was judged as "very low" for diarrhea. OMT turns out to be safe in the treatment of IBS without major adverse effects. OMT may be effective in IBS patients, however the results must be interpreted carefully due to the low methodological quality of the studies.

Postoperative bleeding in coronary artery bypass patients on double antiplatelet therapy: predictive value of preoperative aggregometry.

OBJECTIVES: We tested the possible value of routine aggregometry testing for bleeding prediction following coronary artery bypass grafting in patients who received preoperative double antiplatelet therapy. METHODS: In 226 patients undergoing on-pump isolated coronary artery bypass grafting, aggregometry [adenosine diphosphate (ADP) test and ASPI test] was always prospectively performed by Multiplate® analyser immediately before surgery. We assessed the differences in postoperative bleeding according to the type of double antiplatelet therapy [acetylsalicylic acid plus clopidogrel (ASA+C), or plus ticagrelor (ASA+T)], duration of clopidogrel/ticagrelor withdrawal (0-3 days or ≥ 4 days) and results of aggregometry tests. Multivariable predictors of blood losses were sought by linear regressions (drainage amount at 6, 12 and 24 postoperative hours) and logistic regression (increased bleeding: 75th percentile of blood losses at 6 h, i.e. >450 ml). RESULTS: Overall, postoperative blood losses did not significantly differ between treatment groups (median at 6 h: ASA + C = 335 ml, ASA + T = 300 ml, P = 0.21). With longer withdrawal interval, higher rates of patients with normal ADP-related platelet function were observed in both groups (ASA + C: P = 0.04; ASA + T: P = 0.006) but only in the ASA + T group were blood losses significantly smaller at all 3 time points. Bleeders (>450 ml at 6 h) were significantly less frequent among patients with ADP test showing recovered platelet function (ASA + T: P = 0.002; ASA + C: P = 0.053). The correlation between ADP test result and blood losses amount was stronger in the ASA + T group (e.g. at 6 h: r = -0.6; P < 0.001). In multivariable analyses, the ADP test result independently predicted postoperative bleeding in the ASA + T group and the ASPI test in the ASA + C group. CONCLUSIONS: Aggregometry can help in predicting postoperative bleeding in double antiplatelet therapy patients undergoing coronary artery bypass grafting.

A Very Late Life-Threatening Complication After Percutaneous Closure of an Atrial Septal Defect.

Percutaneous closure is widely recognized as the first therapeutic option in the majority of cases of secundum atrial septal defect (ASD) because of its high effectiveness and safety. Nonetheless, with the progressive increase of implanted devices and follow-up duration, several adverse events, some of them potentially life-threatening, have been reported. We report the case of an asymptomatic aortic erosion that occurred 13 years after the procedure. The main feature of our case is the very late occurrence of a life-threatening asymptomatic complication of ASD percutaneous closure, which should prompt lifelong surveillance in this population.

What do you do with the antiplatelet agents in patients with drug eluting stents who then receive a mechanical valve?

Dual antiplatelet therapy (DAT) with aspirin and clopidogrel is a cornerstone of treatment during and after percutaneous coronary interventions with drug-eluting stent (DES) implantation. Oral anticoagulation (OAC) is the recommended treatment for patients with mechanical heart valves. When patients with DES need a mechanical heart valve or vice versa, we face the difficult choice of their antithrombotic therapy. Different institutions empirically follow a combination of OAC and single or DAT, the so-called triple antithrombotic therapy (TT) aiming to find the best balance between the thrombotic and bleeding risk for this subset of patients. A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether there is an optimal antithrombotic management for patients with DES undergoing mechanical heart valve or vice versa. Altogether, more than 148 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. We conclude that DES implantation in patients who could potentially need valve surgery in the future should be discouraged and bare-metal stent or an aortic bioprosthesis preferred. However, in high-risk patients with DES, the recommendation is to postpone elective surgery for 1 year and, if surgery cannot be deferred, continue aspirin during the perioperative period. Moreover, when OAC is given in combination with clopidogrel and/or low-dose aspirin, the target INR should be 2.0-2.5 (Class IIb, level of evidence C). As per the long-term management, antithrombotic management with DAT alone in mechanical aortic valve replacement might be possible, but there is not enough evidence to support it. The available evidence suggests that triple anticoagulation (OAC + DAT) is associated with the best clinical outcome compared with all the other possible strategies. The duration of TT should be 3 months after sirolimus DES implantation, and 6 months after paclitaxel DES implantation, followed by long-term therapy with OAC plus clopidogrel or aspirin with either PPIs, or H2-receptor antagonists (Class IIa Level of Evidence C).
