Objective To compare efficacy of pharmacotherapies for chronic idiopathic constipation (CIC) based on comparisons to placebo using Bayesian network meta-analysis. Data sources We conducted searches (inception to May 2015) of MEDLINE, EMBASE, Scopus and Cochrane Central, as well as original data from authors or drug companies for the medications used for CIC. Study selection Phase IIB and phase III randomised, placebo-controlled trials (RCT) of ≥4 weeks' treatment for CIC in adults with Rome II or III criteria for functional constipation; trials included at least one of four end points. Data extraction and synthesis Two investigators independently evaluated all full-text articles that met inclusion criteria and extracted data for primary and secondary end points, risk of bias and quality of evidence. Outcomes Primary end points were ≥3 complete spontaneous bowel movements (CSBM)/week and increase over baseline by ≥1 CSBM/week. Secondary end points were change from baseline (Δ b ) in the number of SBM/week and Δ b CSBM/week. Results Twenty-one RCTs (9189 patients) met inclusion and end point criteria: 9 prucalopride, 3 lubiprostone, 3 linaclotide, 2 tegaserod, 1 each velusetrag, elobixibat, bisacodyl and sodium picosulphate (NaP). All prespecified end points were unavailable in four polyethylene glycol studies. Bisacodyl, NaP, prucalopride and velusetrag were superior to placebo for the ≥3 CSBM/week end point. No drug was superior at improving the primary end points on network meta-analysis. Bisacodyl appeared superior to the other drugs for the secondary end point, Δ b in number of SBM/week. Conclusions Current drugs for CIC show similar efficacy. Bisacodyl may be superior to prescription medications for Δ b in the number of SBM/week in CIC.

Objective To perform a systematic review of published literature on adrenal biopsy and to assess its performance in diagnosing adrenal malignancy. Methods Medline In-Process and Other Non-Indexed Citations, MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trial were searched from inception to February 2016. Reviewers extracted data and assessed methodological quality in duplicate. Results We included 32 observational studies reporting on 2174 patients (39.4% women, mean age 59.8 years) undergoing 2190 adrenal mass biopsy procedures. Pathology was described in 1621/2190 adrenal lesions (689 metastases, 68 adrenocortical carcinomas, 64 other malignancies, 464 adenomas, 226 other benign, 36 pheochromocytomas, and 74 others). The pooled non-diagnostic rate (30 studies, 2013 adrenal biopsies) was 8.7% (95%CI: 6–11%). The pooled complication rate (25 studies, 1339 biopsies) was 2.5% (95%CI: 1.5–3.4%). Studies were at a moderate risk for bias. Most limitations related to patient selection, assessment of outcome, and adequacy of follow-up. Only eight studies (240 patients) could be included in the diagnostic performance analysis with a sensitivity and specificity of 87 and 100% for malignancy, 70 and 98% for adrenocortical carcinoma, and 87 and 96% for metastasis respectively. Conclusions Evidence based on small sample size and moderate risk of bias suggests that adrenal biopsy appears to be most useful in the diagnosis of adrenal metastasis in patients with a history of extra-adrenal malignancy. Adrenal biopsy should only be performed if the expected findings are likely to alter the management of the individual patient and after biochemical exclusion of catecholamine-producing tumors to help prevent potentially life-threatening complications.

Although short‐term risks of living donor hepatectomy have been well defined, little is known about the longterm impact. We aimed to perform a systematic follow‐up to screen for unanticipated health consequences of liver donation. All donors who were more than 1 year from donation were invited for a systematic evaluation including physical and laboratory assessment, quality of life questionnaire, and magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP). Those unable to return were offered the questionnaire and laboratory assessment at home. Out of our total of 97 donors, 45 returned for a full assessment and 23 completed labs and survey locally (total n = 68; 70%) after a median of 5.5 years (1.5‐10.9 years) after donation. The only laboratory abnormality was a significant decrease in platelet count (median 198 ×109/L versus 224 ×109/L before donation; P < 0.001), whereas 93% of patients were still above normal limits. No late biliary strictures or other structural abnormalities were found on MRI/MRCP. Liver regeneration was complete. Spleen volume did significantly increase (median 278 cm3 versus 230 cm3 before donation; P < 0.001) without resulting in lowered platelets (P = 0.73). The most common complaints were persistent incisional numbness and changed bowel habits. Seven donors (11%) reported problems obtaining insurance. The vast majority (97%) would have donated again. In conclusion, longterm outcome following liver donation appears satisfactory. None of our donors have developed occult biliary strictures, failure of regeneration, abnormal liver function, or other important health consequences after a median of 5.5 years from surgery. These findings can be used when counseling potential donors in the future. Liver Transplantation 22 934–942 2016 AASLD

CONTEXT:The effectiveness of many interventions aimed at reducing the risk of retinopathy has not been well established.OBJECTIVE:To estimate the effectiveness of nutritional interventions, oxygen saturation targeting, blood transfusion management, and infection prevention on the incidence of retinopathy of prematurity (ROP).DATA SOURCES:A comprehensive search of several databases was conducted, including Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through March 2014.STUDY SELECTION:We included studies that evaluated nutritional interventions, management of supplemental oxygen, blood transfusions, or infection reduction and reported the incidence of ROP and mortality in neonates born at &lt;32 weeks.DATA EXTRACTION:We extracted patient characteristics, interventions, and risk of bias indicators. Outcomes of interest were any stage ROP, severe ROP or ROP requiring treatment, and mortality.RESULTS:We identified 67 studies enrolling 21 819 infants. Lower oxygen saturation targets reduced the risk of developing any stage ROP (relative risk [RR] 0.86, 95% confidence interval [CI], 0.77–0.97) and severe ROP or ROP requiring intervention (RR 0.58, 95% CI, 0.45–0.74) but increased mortality (RR 1.15, 95% CI, 1.04–1.29). Aggressive parenteral nutrition reduced the risk of any stage ROP but not severe ROP. Supplementation of vitamin A, E, or inositol and breast milk feeding were beneficial but only in observational studies. Use of transfusion guidelines, erythropoietin, and antifungal agents were not beneficial.LIMITATIONS:Results of observational studies were not replicated in randomized trials. Interventions were heterogeneous across studies.CONCLUSIONS:At the present time, there are no safe interventions supported with high quality evidence to prevent severe ROP.

AbstractObjective:To develop clinical practice guidelines for the management of patients with primary aldosteronism.Participants:The Task Force included a chair, selected by the Clinical Guidelines Subcommittee of the Endocrine Society, six additional experts, a methodologist, and a medical writer. The guideline was cosponsored by American Heart Association, American Association of Endocrine Surgeons, European Society of Endocrinology, European Society of Hypertension, International Association of Endocrine Surgeons, International Society of Endocrinology, International Society of Hypertension, Japan Endocrine Society, and The Japanese Society of Hypertension. The Task Force received no corporate funding or remuneration.Evidence:We searched for systematic reviews and primary studies to formulate the key treatment and prevention recommendations. We used the Grading of Recommendations, Assessment, Development, and Evaluation group criteria to describe both the quality of evidence and the strength of recommendations. We used “recommend” for strong recommendations and “suggest” for weak recommendations.Consensus Process:We achieved consensus by collecting the best available evidence and conducting one group meeting, several conference calls, and multiple e-mail communications. With the help of a medical writer, the Endocrine Society's Clinical Guidelines Subcommittee, Clinical Affairs Core Committee, and Council successfully reviewed the drafts prepared by the Task Force. We placed the version approved by the Clinical Guidelines Subcommittee and Clinical Affairs Core Committee on the Endocrine Society's website for comments by members. At each stage of review, the Task Force received written comments and incorporated necessary changes.Conclusions:For high-risk groups of hypertensive patients and those with hypokalemia, we recommend case detection of primary aldosteronism by determining the aldosterone-renin ratio under standard conditions and recommend that a commonly used confirmatory test should confirm/exclude the condition. We recommend that all patients with primary aldosteronism undergo adrenal computed tomography as the initial study in subtype testing and to exclude adrenocortical carcinoma. We recommend that an experienced radiologist should establish/exclude unilateral primary aldosteronism using bilateral adrenal venous sampling, and if confirmed, this should optimally be treated by laparoscopic adrenalectomy. We recommend that patients with bilateral adrenal hyperplasia or those unsuitable for surgery should be treated primarily with a mineralocorticoid receptor antagonist.

BACKGROUNDElevated cardiac troponin (cTn) is often observed in patients with acute decompensated heart failure (ADHF). We assessed the magnitude of association and quality of supporting evidence between cTn and clinically important outcomes in persons hospitalized for ADHF.METHODSWe searched MEDLINE In‐Process & Other Non‐Indexed Citations, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus from inception through February 28, 2015. The outcomes analyzed included hospital length of stay (LOS), readmissions, and mortality. Random effects meta‐analysis was used to combine outcomes across studies.RESULTSWe included 26 clinical studies. A detectable or elevated cTn was associated with increased LOS (odds ratio [OR]: 1.05; 95% confidence interval [CI]: 1.01‐1.10), increased in‐hospital mortality (OR: 2.57; 95% CI: 2.27‐2.91), and a composite of mortality and major adverse events (OR: 1.33; 95% CI: 1.03‐1.71) during hospitalization. ADHF patients with a detectable or elevated cTn were at increased risk for mortality and composite of mortality and readmission over the short term (mortality OR: 2.11; 95% CI: 1.43‐3.12; composite OR: 2.81; 95% CI: 1.60‐4.92), intermediate term (mortality OR: 2.21; 95% CI: 1.46‐3.35; composite OR: 2.30; 95% CI: 1.78‐2.99), and long term (mortality OR: 3.69; 95% CI: 2.64‐5.18; composite OR: 3.49; 95% CI: 2.08‐5.84). The overall confidence in estimates was moderate.CONCLUSIONSAmong ADHF patients, a detectable or elevated cTn identifies subjects at increased risk for adverse clinical outcomes during acute hospitalization and those at higher risk for postdischarge mortality and composite of readmission and mortality.
