RESUMO
BACKGROUND: Anastomotic leakage (AL) is one of the most significant complications after colorectal surgery, affecting length of stay, patient morbidity, mortality, and long-term oncological outcome. Serum C-reactive protein (CRP) level rises in infective and inflammatory states. Elevated CRP has been shown to be associated with anastomotic leak. OBJECTIVE: Perform a meta-analysis of current CRP data in AL after colorectal surgery. DATA SOURCES: MEDLINE, EMBASE, CINAHL, CENTRAL databases STUDY SELECTION: Comparative studies studying serum CRP levels in adult patients with and without AL after colorectal surgery. INTERVENTION(S): Elective and emergency open, laparoscopic or robotic colorectal excisions for cancer and benign pathology. MAIN OUTCOME MEASURES: Mean serum CRP measurements between post-operative days (POD) 1 through 7 in patients with and without AL. Perform ROC analysis to determine cut-off CRP values to indicate AL. RESULTS: Twenty-three studies with 6647 patients (482 AL). Pooled mean time to diagnosis of AL was 7.70 days. AL associated with higher CRP on POD1 (mean difference (MD) 15.19, 95% CI 5.88-24.50, p = 0.001), POD2 (MD 51.98, 05% CI 37.36-66.60, p < 0.00001), POD3 (MD 96.92, 95% CI 67.96-125.89, p < 0.00001), POD4 (MD 93.15, 95% CI 69.47-116.84, p < 0.00001), POD5 (MD 112.10, 95% CI 89.74-134.45, p < 0.00001), POD6 (MD 98.38, 95% CI 80.29-116.46, p < 0.00001), and POD7 (MD 106.41, 95% CI 75.48-137.35, p < 0.00001) compared with no AL. ROC analysis identified a cut-off CRP of 148 mg/l on POD3 with sensitivity and specificity of 95%. On POD4 through POD7, cut-off levels were 123 mg/l, 115 mg/l, 105 mg/l, and 96 mg/l, respectively, with sensitivity and specificity of 100%. LIMITATIONS: Study heterogeneity, some characteristics unreported, no RCT CONCLUSIONS: AL is associated with higher CRP levels on each post-operative day compared to no AL after colorectal surgery. The cut-off CRP values can be used to predict AL to expedite investigation and treatment.

OBJECTIVE: To design and investigate a pharmacist-run intervention using low health literacy flashcards and a smartphone-activated quick response (QR) barcoded educational flashcard video to increase medication adherence and disease state understanding. DESIGN: Prospective, matched, quasi-experimental design. SETTING: County health system in Dallas, Texas. PARTICIPANTS: Sixty-eight primary care patients prescribed targeted heart failure, hypertension, and diabetes medications INTERVENTION: Low health literacy medication and disease specific flashcards, which were also available as QR-coded online videos, were designed for the intervention patients. The following validated health literacy tools were conducted: Newest Vital Sign (NVS), Rapid Estimate of Adult Literacy Medicine-Short Form, and Short Assessment of Health Literacy-50. MAIN OUTCOME MEASURES: The primary outcome was the difference in medication adherence at 180 days after pharmacist intervention compared with the control group, who were matched on the basis of comorbid conditions, targeted medications, and medication class. Medication adherence was measured using a modified Pharmacy Quality Alliance proportion of days covered (PDC) calculation. Secondary outcomes included 90-day PDC, improvement of greater than 25% in baseline PDC, and final PDC greater than 80%. Linear regression was performed to evaluate the effect of potential confounders on the primary outcome. RESULTS: Of the 34 patients receiving the intervention, a majority of patients scored a high possibility of limited health literacy on the NVS tool (91.2%). The medication with the least adherence at baseline was metformin, followed by angiotensin-converting enzyme inhibitors and beta blockers. At 180 days after intervention, patients in the intervention group had higher PDCs compared with their matched controls (71% vs. 44%; P = 0.0069). CONCLUSION: The use of flashcards and QR-coded prescription bottles for medication and disease state education is an innovative way of improving adherence to diabetes, hypertension, and heart failure medications in a low-health literacy patient population.

BACKGROUND: Ankle fractures, which usually occur after a twisting incident, are a diverse collection of injuries with different levels of complexity and severity. They have an incidence of 1 in 1000 a year in children. Treatment generally involves splints and casts for minor fractures and surgical fixation with screws, plates and pins followed by immobilisation for more serious fractures. OBJECTIVES: To assess the effects (benefits and harms) of different interventions for treating ankle fractures in children. SEARCH METHODS: We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (22 September 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 8), MEDLINE (1946 to September Week 2 2015), MEDLINE In-Process & Other Non-Indexed Citations (21 September 2015), EMBASE (1980 to 2015 Week 38), CINAHL (1937 to 22 September 2015), trial registers (17 February 2015), conference proceedings and reference lists of articles. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials evaluating interventions for treating ankle fractures in children. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles, abstracts and full articles for inclusion, assessed risk of bias and collected data. We undertook no meta-analysis. MAIN RESULTS: We included three randomised controlled trials reporting results for 189 children, all of whom had a clinical diagnosis of a "low risk" ankle fracture. These were predominantly classified as undisplaced Salter-Harris type I fractures of the distal fibula. All three trials compared non-surgical management options. The three trials were at high risk of bias, primarily relating to the impracticality of blinding participants and treating clinicians to the allocated interventions.Two trials compared the Aircast Air-Stirrup ankle brace versus a rigid cast, which was a removable fibreglass posterior splint in one trial (trial A) and a below-knee fibreglass walking cast in the other trial (trial B). In trial A, both devices were removed at around two weeks. In trial B, removal of the brace was optional after five days, while the walking cast was removed after three weeks. There was low-quality evidence of clinically important differences in function scores at four weeks in favour of the brace groups of both trials. Function was measured using the Activities Scale for Kids-performance (ASKp; score range 0 to 100, higher scores mean better function) in trial A and using a modified version of the ASKp score (range 0 to 100%, higher percentages mean better function) in trial B. The results for trial A (40 participants) were median 91.9 in the brace group versus 84.2 in the splint group. The results for trial B (104 participants) were 91.3% versus 85.3%; mean difference (MD) 6.00% favouring brace (95% confidence interval (CI) 1.38% to 10.62%). Trial B indicated that 5% amounted to a clinically relevant difference in the modified ASKp score. Neither trial reported on unacceptable anatomy or related outcomes or long-term follow-up. There was very low-quality evidence relating to adverse events, none of which were serious. Trial A found twice as many children with pressure-related complications in the brace group (10 of 20 versus 5 of 20). In contrast, trial B found four times as many children in the cast group had adverse outcomes assessed in terms of an unscheduled visit to a healthcare provider (4 of 54 versus 16 of 50). Both trials linked some of the adverse events in the brace group with the failure to wear a protective sock. There was very low-quality evidence indicating an earlier return to pre-injury activity in the brace groups in both trials. Trial B provided low-quality evidence that children much prefer five days or more wearing an ankle brace than three weeks immobilised in a walking ankle cast. There was moderate-quality evidence of a lack of difference between the two groups in pain at four weeks.The third trial compared the Tubigrip bandage plus crutches and advice versus a plaster of Paris walking cast for two weeks and reported results at four weeks' follow-up for 45 children with an inversion injury of the ankle. The trial found very low-quality evidence of little difference in pain and function between the two groups, measured using a non-validated pain and function score at four weeks. The trial did not report on adverse effects. There was very low-quality evidence of an earlier return to normal activities, averaging six days, in children treated with Tubigrip (mean 14.17 days for Tubigrip versus 20.19 days for cast; MD -6.02 days, 95% CI -8.92 to -3.12 days).Recent evidence from magnetic resonance imaging studies of the main category of injury evaluated in these three trials suggests that most of the injuries in these trials were sprains or bone bruises rather than fractures of the distal fibular growth plate. AUTHORS' CONCLUSIONS: There is low-quality evidence of a quicker recovery of self reported function at four weeks in children with clinically diagnosed low-risk ankle fractures who are treated with an ankle brace compared with those treated with a rigid cast, especially a non-removable walking cast. There is otherwise a lack of evidence from randomised controlled trials to inform clinical practice for children with ankle fractures. Research to identify and address priority questions on the treatment of these common fractures is needed.

PURPOSE: The purpose of our study was to compare the agreement of emergency physician diagnoses relative to the 1991 American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) and 2001 ACCP/SCCM/European Society of Intensive Care Medicine/American Thoracic Society/Surgical Infection Society internationally accepted definitions of sepsis, severe sepsis, and septic shock. MATERIALS AND METHODS: This study was an observational cohort study of adult patients presenting to the emergency department (ED) with a chief complaint suggestive of infection over a 6-week period, during a daily enrollment schedule from 7:00 am to 10:00 pm. Patients were categorized as having "no sepsis," "sepsis," "severe sepsis," or "septic shock" based on ED physician diagnosis, the 1991 definitions, or 2001 definitions. Agreement statistics were performed. RESULTS: A total of 1275 patients were enrolled with age 50.1 ± 21.7 years and 59.1% were female. Among the enrolled patients, 228 were identified as having a source of infection. Temperature, heart rate, and white blood cell count were significantly higher in patients with infection, compared with those without (P < .001). The odds ratio for disagreement between a physician-designated no sepsis diagnosis and the 1991 definitions was 4.47 (95% confidence interval, 3.01-7.53) and 5.96 (3.78-9.46) between the same physician-designated diagnosis and the 2001 definitions. The odds ratios for disagreement of a severe sepsis physician diagnosis in relation to the 1991 and 2001 definitions were 0.06 (0.01-0.19) and 0.06 (0.01-0.20), respectively. The 1991 and 2001 consensus definitions had strong agreement, with κ = 0.86 and 91.2% agreement. No agreement was found between the physician diagnosis and 1991 consensus sepsis definitions (κ = 0.11 and 52.2% agreement) or between the physician diagnosis and the 2001 consensus sepsis definitions (κ = 0.13 and 50.0% agreement). CONCLUSIONS: Our study showed that ED physician diagnosis of sepsis may disagree with the international definitions such that severe sepsis is underrecognized by clinical judgment alone. Although these results are limited to a single center, we raise concern that early treatments for these high-risk patients may be delayed due to inaccurate clinical diagnosis. Efforts are needed to increase the application of sepsis guideline definitions to better identify ED patients with this potentially deadly condition.

BACKGROUND: Little is known about the use and effectiveness of over-the-counter (OTC) fish oil supplements for triglyceride (TG) lowering. OBJECTIVES: To (1) perform a medication-use evaluation (MUE) and (2) assess the efficacy of OTC fish oil. METHODS: Retrospective, observational cohort study using electronic medical records and the pharmacy database from Parkland Health and Hospital System in Dallas, Texas. Parkland is a tax-supported county institution that provides patients with single-brand OTC fish oil. Two separate analyses were conducted. Six hundred seventeen patients (prescribed fish oil between July 1, 2012, and August 31, 2012) were included in the MUE analysis and 235 patients (109 fish oil, 72 fenofibrate, and 54 gemfibrozil, prescribed between January 1, 2012, and July 31, 2013) were included in the efficacy analysis. The main outcome measure for the MUE was fish oil prescribing habits including dosages and patient adherence, as defined by medication possession ratio. The main outcome measure for the efficacy analysis was change in lipids measured using the last value before fish oil treatment and the first value after fish oil treatment. RESULTS: MUE: 617 patients received prescriptions for OTC fish oil. Sixty-four percent were prescribed a total daily dose of 2000 mg. Only 25% of patients were adherent. Efficacy analysis: despite being prescribed suboptimal doses, fish oil reduced TGs by 29% (95% confidence interval, 34.3-22.7). Compared with fish oil therapy, fibrate therapy resulted in a greater TG reduction: 48.5% (55.1-41.0) with fenofibrate and 49.8% (57.6-40.5) with gemfibrozil (P < .0001, both medications compared with fish oil). CONCLUSIONS: Health care providers prescribe suboptimal doses of fish oil, and adherence is poor. Even at low doses (2 g/d), though, fish oil lowers TGs by 29%.

The succession of developmental events in the C. elegans larva is governed by the heterochronic genes. When mutated, these genes cause either precocious or retarded developmental phenotypes, in which stage-specific patterns of cell division and differentiation are either skipped or reiterated, respectively. We identified a new heterochronic gene, lin-46, from mutations that suppress the precocious phenotypes caused by mutations in the heterochronic genes lin-14 and lin-28. lin-46 mutants on their own display retarded phenotypes in which cell division patterns are reiterated and differentiation is prevented in certain cell lineages. Our analysis indicates that lin-46 acts at a step immediately downstream of lin-28, affecting both the regulation of the heterochronic gene pathway and execution of stage-specific developmental events at two stages: the third larval stage and adult. We also show that lin-46 is required prior to the third stage for normal adult cell fates, suggesting that it acts once to control fates at both stages, and that it affects adult fates through the let-7 branch of the heterochronic pathway. Interestingly, lin-46 encodes a protein homologous to MoeA of bacteria and the C-terminal domain of mammalian gephyrin, a multifunctional scaffolding protein. Our findings suggest that the LIN-46 protein acts as a scaffold for a multiprotein assembly that controls developmental timing, and expand the known roles of gephyrin-related proteins to development.
