RESUMEN
BACKGROUND: Local recurrence (LR) rates of dermatofibrosarcoma protuberans (DFSP) treated with different surgical modalities are unknown. OBJECTIVE: To evaluate the differences in LR rates of DFSP treated with wide local excision (WLE) versus Mohs micrographic surgery (MMS). MATERIALS AND METHODS: Pertinent studies of DFSP treated with either WLE or MMS were identified through a search of multiple databases, including Ovid MEDLINE (1946-2018), Embase (1988-2018), Web of Science (1975-2018), and Scopus (1970-2018). Comparative 2-arm and noncomparative single-arm studies were assessed through meta-analyses. RESULTS: Of the 517 studies identified, 88 met inclusion criteria (12 comparative studies; 76 single-arm studies). In the 12 comparative studies, 352 patients with DFSP underwent MMS and 777 patients with DFSP underwent WLE. The LR rate was 1.7% after MMS and 3.7% after WLE (odds ratio, 1.549; 95% CI, 0.710-3.381; p = .27). In the 76 noncomparative studies, 980 patients underwent MMS (LR rate, 1.5%; 95% CI, 0.9%-2.1%; p < .001), and 2,215 patients underwent WLE (LR rate, 9.4%; 95% CI, 7.5%-11.3%; p < .001). CONCLUSION: The LR rate of DFSP in patients treated with MMS is lower than in patients treated with WLE. Because of high rates of postoperative DFSP LR, MMS should be strongly considered when available.

BACKGROUND: Comprehensive treatment recommendations for Merkel cell carcinoma are complex. We aimed to systematically review the published data on recurrence and mortality rates associated with various treatment approaches for Merkel cell carcinoma. METHODS: Search of MEDLINE, Embase, Web of Science, and Scopus from inception to August 2015. Studies were included that reported comparative survival and recurrence data for two or more treatment modalities. Two reviewers independently reviewed and abstracted recurrence and mortality rates. Event rates for individual treatment arms in each study were pooled and meta-analyzed across studies using a random-effects model. RESULTS: Fifty-two retrospective studies met inclusion criteria, revealing a total of 1,804 patients with primary Merkel cell carcinoma with data available for analyses. The recurrence rate was higher for surgery alone (55.0%) versus a combination of surgery and radiotherapy (39.0%) (odds ratio, 2.089; 95% CI, 1.374-3.177; P < 0.001). Combination therapy including surgery, radiotherapy, and chemotherapy had a higher mortality rate (44.6%) than did combined surgery and radiotherapy (23.2%) (odds ratio, 2.688; 95% CI, 1.196-6.037; P = 0.02). CONCLUSIONS: The treatment of Merkel cell carcinoma with surgery plus adjuvant radiotherapy may produce lower recurrence rates.

BACKGROUND: Complete removal of melanoma is a primary goal of excision, and local recurrence is one measure to evaluate the efficacy of surgical technique. OBJECTIVE: To compare published local recurrence rates for melanoma treated with Mohs micrographic surgery (MMS) or staged excision versus wide local excision (WLE). METHODS AND MATERIALS: Search of 6 databases identified comparative and noncomparative studies that reported local recurrence rates after MMS, staged excision, or WLE for melanoma. Random-effects meta-analysis was used to estimate odds ratios and 95% confidence interval (CI) from comparative studies and event rates from noncomparative studies. RESULTS: Of the 71 studies included (16,575 patients), 12 were comparative studies (2,683 patients) and 56 were noncomparative studies (13,698 patients). Comparative studies showed increased recurrence after WLE compared with MMS or staged excision (odds ratio [OR], 2.5; 95% CI, 1.4-4.6) and compared with MMS alone (OR, 3.3; 95% CI, 1.8-5.9). Pooled data from comparative and noncomparative studies showed a local recurrence rate of 7% after WLE (95% CI, 5%-11%), 3% after staged excision (95% CI, 2%-4%), and less than 1% after MMS (95% CI, 0%-1%). Statistical heterogeneity was moderate to high. CONCLUSION: Local recurrence of melanoma is significantly lower after MMS (<1%) and staged excision (3%) compared with WLE (7%).

AIMS: Percutaneous mitral balloon valvotomy PMBV is an acceptable alternative to Mitral valve surgery for patients with mitral stenosis. The purpose of this study was to explore the immediate results of PMBV with respect to echocardiographic changes, outcomes, and complications, using a meta-analysis approach. METHODS: MEDLINE, and EMBASE databases were searched (01/2012 to 10/2018) for original research articles regarding the efficacy and safety of PMBV. Two reviewers independently screened references for inclusion and abstracted data including article details and echocardiographic parameters before and 24-72 h after PMBV, follow-up duration, and acute complications. Disagreements were resolved by third adjudicator. Quality of all included studies was evaluated using the Newcastle-Ottawa Scale NOS. RESULTS: 44/990 references met the inclusion criteria representing 6537 patients. Our findings suggest that PMBV leads to a significant increase in MVA (MD = 0.81 cm2; 0.76-0.87, p < 0.00001), LVEDP (MD = 1.89 mmHg; 0.52-3.26, p = 0.007), LVEDV EDV (MD = 5.81 ml; 2.65-8.97, p = 0.0003) and decrease in MPG (MD = -7.96 mmHg; -8.73 to -7.20, p < 0.00001), LAP (MD = -10.09 mmHg; -11.06 to -9.12, p < 0.00001), and SPAP (MD = -15.55 mmHg; -17.92 to -13.18, p < 0.00001). On short term basis, the pooled overall incidence estimates of repeat PMBV, mitral valve surgery, post-PMBV severe MR, and post-PMBV stroke, and systemic thromboembolism were 0.5%, 2%, 1.4%, 0.4%, and 0.7%% respectively. On long term basis, the pooled overall incidence estimates of repeat PMBV, mitral valve surgery, post-PMBV severe MR, and post-PMBV stroke, systemic thromboembolism were 5%, 11.5%, 5.5%, 2.7%, and 1.7% respectively. CONCLUSION: PMBV represents a successful approach for patients with mitral stenosis as evidenced by improvement in echocardiographic parameters and low rate of complications.
RESUMEN
BACKGROUND: Ketamine, a glutamate N-methyl-d-aspartate receptor antagonist, has shown rapid antidepressant effects in treatment-resistant depression. We conducted a systematic review of studies evaluating the efficacy of intravenous ketamine augmentation in treatment-resistant depression patients with bipolar disorder. METHODS: Major databases were searched for open-label and randomized controlled trials (RCT). Two independent reviewers screened and selected the studies that met the inclusion criteria. Studies were selected following the standard Cochrane methodology, and the findings are reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Methodological quality of the included studies was assessed using standardized measures. RESULTS: A total of 1442 articles were screened. Five studies were included in the systematic review (3 RCTs and 2 open-label studies) enrolling 110 subjects (mean age, 45.54 ± 12.65 years; 68.18% female). All the RCTs and open-label studies showed improvement in depressions symptoms after receiving a single infusion of ketamine. Included studies also suggested improvement in suicidal ideation and anhedonia after ketamine infusion. Dissociation and transient increase in blood pressure were the most common reported adverse effects with ketamine. Ketamine infusions did not increase mania symptoms. CONCLUSIONS: Limited data show efficacy and feasibility of intravenous racemic ketamine in treatment-resistant bipolar depression. Further studies with larger sample size are required to strengthen the evidence.

BACKGROUND: This systematic review appraises the evidence from human clinical trials comparing postoperative pain scores and opioid consumption in patients receiving intra-articular ketamine versus other modalities of analgesia after orthopedic joint procedures. METHODS: Studies were identified from Embase, Scopus, and OVID Medline databases. Included studies compared patients receiving intra-articular ketamine versus other modalities of analgesia. The primary outcome of interest was postprocedural pain score and total opioid consumption, whereas secondary outcomes included time to rescue analgesic medication request, active range of motion, time to mobilization, and adverse effects. RESULTS: Seventeen studies were included. Dosage of ketamine varied widely from 0.25 to 2 mg/kg. Fifteen of 17 demonstrated decreased overall pain scores and decreased total postoperative opioid consumption in patients receiving intra-articular ketamine versus control groups. Included studies generally demonstrated reduced time to mobilization and increased latency until rescue analgesic medication in the intra-articular ketamine group. CONCLUSIONS: Patients who received intra-articular ketamine generally reported lower pain scores and had lower postoperative opioid consumption after orthopedic joint procedures. This suggests that the intra-articular route of ketamine delivery may be a useful analgesic modality, although future larger-scale trials should explore its pharmacokinetics, optimal dosing, safety, and cost-effectiveness.

INTRODUCTION: Chronic kidney disease (CKD) is widely prevalent, associated with morbidity and mortality, but may be lessened with timely implementation of evidence-based strategies including blood pressure (BP) control. Nonetheless, an evidence-practice gap persists. We synthesize the evidence for clinician-facing interventions to improve hypertension management in CKD patients in primary care. METHODS: Electronic databases and related publications were queried for relevant studies. We used a conceptual model to address heterogeneity of interventions. We conducted a quantitative synthesis of interventions on blood pressure (BP) outcomes and a narrative synthesis of other CKD relevant clinical outcomes. Planned subgroup analyses were performed by (1) study design (randomized controlled trials (RCTs) or nonrandomized studies (NRS)); (2) intervention type (guideline-concordant decision support, shared care, pharmacist-facing); and (3) use of behavioral/implementation theory. RESULTS: Of 2704 manuscripts screened, 73 underwent full-text review; 22 met inclusion criteria. BP target achievement was reported in 15 and systolic BP reduction in 6 studies. Among RCTs, all interventions had a significant effect on BP control, (pooled OR 1.21; 95% CI 1.07 to 1.38). Subgroup analysis by intervention type showed significant effects for guideline-concordant decision support (pooled OR 1.19; 95% CI 1.12 to 1.27) but not shared care (pooled OR 1.71; 95% CI 0.96 to 3.03) or pharmacist-facing interventions (pooled OR 1.04; 95% CI 0.82 to 1.34). Subgroup analysis finding was replicated with pooling of RCTs and NRS. The five contributing studies showed large and significant reduction in systolic BP (pooled WMD - 3.86; 95% CI - 7.2 to - 0.55). Use of a behavioral/implementation theory had no impact, while RCTs showed smaller effect sizes than NRS. DISCUSSION: Process-oriented implementation strategies used with guideline-concordant decision support was a promising implementation approach. Better reporting guidelines on implementation would enable more useful synthesis of the efficacy of CKD clinical interventions integrated into primary care.

OBJECTIVES: The purpose of this study was to determine if health literacy is associated with mortality, hospitalizations, or emergency department (ED) visits among patients living with heart failure (HF). BACKGROUND: Growing evidence suggests an association between health literacy and health-related outcomes in patients with HF. METHODS: We searched Embase, MEDLINE, PsycINFO, and EBSCO CINAHL from inception through January 1, 2019, with the help of a medical librarian. Eligible studies evaluated health literacy among patients with HF and assessed mortality, hospitalizations, and ED visits for all causes with no exclusion by time, geography, or language. Two reviewers independently selected studies, extracted data, and assessed the methodological quality of the identified studies. RESULTS: We included 15 studies, 11 with an overall high methodological quality. Among the observational studies, an average of 24% of patients had inadequate or marginal health literacy. Inadequate health literacy was associated with higher unadjusted risk for mortality (risk ratio [RR]: 1.67; 95% confidence interval [CI]: 1.18 to 2.36), hospitalizations (RR: 1.19; 95% CI: 1.09 to 1.29), and ED visits (RR: 1.17; 95% CI: 1.03 to 1.32). When the adjusted measurements were combined, inadequate health literacy remained statistically associated with mortality (RR: 1.41; 95% CI: 1.06 to 1.88) and hospitalizations (RR: 1.12; 95% CI: 1.01 to 1.25). Among the 4 interventional studies, 2 effectively improved outcomes among patients with inadequate health literacy. CONCLUSIONS: In this study, the estimated prevalence of inadequate health literacy was high, and inadequate health literacy was associated with increased risk of death and hospitalizations. These findings have important clinical and public health implications and warrant measurement of health literacy and deployment of interventions to improve outcomes.

BACKGROUND: No consensus exists regarding optimal strategy for antifungal prophylaxis following lung transplant. OBJECTIVE: To review data regarding antifungal prophylaxis on the development of fungal infections. STUDY SELECTION/APPRAISAL: We searched MEDLINE, Embase, and Scopus for eligible articles through December 10, 2019. Observational or controlled trials published after January 1, 2001, that pertained to the prevention of fungal infections in adult lung recipients were reviewed independently by two reviewers for inclusion. METHODS: Of 1702 articles screened, 24 were included. Data were pooled using random effects model to evaluate for the primary outcome of fungal infection. Studies were stratified by prophylactic strategy, medication, and duration (short term < 6 months and long term ≥ 6 months). RESULTS: We found no difference in the odds of fungal infection with universal prophylaxis (49/101) compared to no prophylaxis (36/93) (OR 0.76, CI: 0.03-17.98; I2 = 93%) and preemptive therapy (25/195) compared to universal prophylaxis (35/222) (OR 0.91, CI: 0.06-13.80; I2 = 93%). The cumulative incidence of fungal infections within 12 months was not different with nebulized amphotericin (0.08, CI: 0.04-0.13; I2 = 87%) compared to systemic triazoles (0.07, CI: 0.03-0.11; I2 = 21%) (P = .65). Likewise, duration of prophylaxis did not impact the incidence of fungal infections (short term: 0.11, CI: 0.05-0.17; I2 = 89%; long term: 0.06, CI: 0.03-0.08; I2 = 51%; P = .39). CONCLUSIONS: We have insufficient evidence to support or exclude a benefit of antifungal prophylaxis.

OBJECTIVE: Bioprosthetic valves are being used with increased frequency for valve replacement, with controversy regarding risk:benefit ratio compared with mechanical valves in younger patients. However, prior studies have been too small to provide comparative estimates of less common but serious adverse events such as infective endocarditis. We aimed to compare the incidence of infective endocarditis between bioprosthetic valves and mechanical valves. METHODS: We searched PubMed, Cochrane, EMBASE, Scopus and Web of Science from inception to April 2018 for studies comparing left-sided aortic and mitral bioprosthetic to mechanical valves for randomised trials or observational studies with propensity matching. We used random-effects model for our meta-analysis. Our primary outcome of interest was the rate of infective endocarditis at follow-up. RESULTS: 13 comparison groups with 43 941 patients were included. Mean age was 59±7 years with a mean follow-up of 10.4±5.0 years. Patients with bioprosthetic valves had a higher risk of infective endocarditis compared with patients receiving mechanical valves (OR 1.59, 95% CI 1.35 to 1.88, p<0.001) with an absolute risk reduction of 9 per 1000 (95% CI 6 to 14). Heterogeneity within the included studies was low (I2=0%). Exclusion of the study with maximum weight did not change the results of the analysis (OR 1.57, 95% CI 1.14 to 2.17, p=0.006). A meta-regression of follow-up time on incidence of infective endocarditis was not statistically significant (p=0.788) indicating difference in follow-up times did not alter the pooled risk of infective endocarditis. CONCLUSIONS: Bioprosthetic valves may be associated with a higher risk of infective endocarditis. These data should help guide the discussion when deciding between bioprosthetic and mechanical valves in individual patients.

OBJECTIVE: Shared decision-making (SDM) is a process of collaboration between patients and clinicians. An increasing number of educational programs to teach SDM have been developed. We aimed to summarize and evaluate the body of evidence assessing the outcomes of these programs. METHODS: We conducted a systematic review of studies that aimed to teach SDM to medical trainees. Reviewers worked independently and in duplicate to select studies, extract data and evaluate the risk of bias. RESULTS: Eighteen studies were included. Most studies focused on residents/fellows (61 %) and combined a didactic component with a practical experience (50 % used a standardized patient). Overall, participants reported satisfaction with the courses. The effects on knowledge, attitudes/confidence and comfort with SDM were small; no clear improvement on SDM skills was noted. Evaluation of clinical behavior and outcomes was limited (3/18 studies). Studies had moderate risk of bias. CONCLUSION: Very low quality evidence suggests that educational programs for teaching SDM to medical trainees are viewed as satisfactory and have a small impact on knowledge and comfort with SDM. Their impact on clinical skills, behaviors and patient outcomes is less clear. PRACTICAL IMPLICATIONS: Integration of formal and systematic outcomes evaluation (effects on behavior/clinical practice) should be part of future programs.

BACKGROUND AND OBJECTIVES: High-flow nasal cannula (HFNC) oxygen may provide tailored benefits in patients with preset treatment limitations. The objective of this study was to assess the effectiveness of HFNC oxygen in patients with do-not-intubate (DNI) and/or do-not-resuscitate (DNR) orders. METHODS: We conducted a systematic review of interventional and observational studies. A search was performed using MEDLINE, EMBASE, CINAHL, Scopus, and Web of Science, from inception to October 15, 2018. RESULTS: We included six studies evaluating 293 patients. All studies had a high risk of bias. The hospital mortality rates of patients with DNI and/or DNR orders receiving HFNC oxygen were variable and ranged from 40% to 87%. In two before and after studies, the initiation of HFNC oxygen was associated with improved oxygenation and reduced respiratory rates. One comparative study found no difference in dyspnea reduction or morphine doses between patients using HFNC oxygen versus conventional oxygen. No studies evaluated quality of life in survivors or quality of death in nonsurvivors. HFNC was generally well tolerated with few adverse events identified. CONCLUSIONS: While HFNC oxygen remains a viable treatment option for hospitalized patients who have acute respiratory failure and a DNI and/or DNR order, there is a paucity of high-quality, comparative, effectiveness data to guide the usage of HFNC oxygen compared with other treatments, such as noninvasive ventilation, conventional oxygen, and palliative opioids.

PURPOSE: To assess the rates and variability of do-not-intubate orders in patients with acute respiratory failure. METHODS: We conducted a systematic review of observational studies that enrolled adult patients with acute respiratory failure requiring noninvasive ventilation or high-flow nasal cannula oxygen from inception to 2019. RESULTS: Twenty-six studies evaluating 10,755 patients were included. The overall pooled rate of do-not-intubate orders was 27%. The pooled rate of do-not-intubate orders in studies from North America was 14% (range 9-22%), from Europe was 28% (range 13-58%), and from Asia was 38% (range 9-83%), p = 0.001. Do-not-intubate rates were higher in studies with higher patient age and in studies where do-not-intubate decisions were made without reported patient/family input. There were no significant differences in do-not-intubate orders according to illness severity, observed mortality, malignancy comorbidity, or methodological quality. Rates of do-not-intubate orders increased over time from 9% in 2000-2004 to 32% in 2015-2019. Only 12 studies (46%) reported information about do-not-intubate decision-making processes. Only 4 studies (15%) also reported rates of do-not-resuscitate. CONCLUSIONS: One in four patients with acute respiratory failure (who receive noninvasive ventilation or high-flow nasal cannula oxygen) has a do-not-intubate order. The rate of do-not-intubate orders has increased over time. There is high inter-study variability in do-not-intubate rates-even when accounting for age and illness severity. There is high variability in patient/family involvement in do-not-intubate decision making processes. Few studies reported differences in rates of do-not-resuscitate and do-not-intubate-even though recovery is very different for acute respiratory failure and cardiac arrest.

OBJECTIVE: To conduct a systematic review and meta-analysis describing the association of thyroid function with posttraumatic stress disorder (PTSD) in adults. METHODS: The authors conducted a comprehensive search from databases' inception to July 20, 2018. The meta-analysis included studies that reported mean values and standard deviation (SD) of thyroid hormone levels (thyroid-stimulating hormone [TSH], free thyroxine [FT4], free triiodothyronine [FT3], total T4 [TT4], and total T3 [TT3]) in patients with PTSD compared with controls. Five reviewers worked independently, in duplicate, to determine study inclusion, extract data, and assess risk of bias. The mean value and SD of the thyroid function tests were used to calculate the mean difference for each variable. Random-effects models for meta-analyses were applied. RESULTS: The meta-analysis included 10 observational studies at low-to-moderate risk of bias. Studies included 674 adults (373 PTSD, 301 controls). The meta-analytic estimates showed higher levels of FT3 (+0.28 pg/mL; P = .001) and TT3 (+18.90 ng/dL; P = .005) in patients with PTSD compared to controls. There were no differences in TSH, FT4, or TT4 levels between groups. In the subgroup analysis, patients with combat-related PTSD still had higher FT3 (+0.36 pg/mL; P = .0004) and higher TT3 (+31.62 ng/dL; P<.00001) compared with controls. Conversely, patients with non-combat-related PTSD did not have differences in FT3 or TT3 levels compared with controls. CONCLUSION: There is scarce evidence regarding the association of thyroid disorders with PTSD. These findings add to the growing literature suggesting that thyroid function changes may be associated with PTSD.

BACKGROUND: Prompt, complete, and accurate information transfer at the time of discharge between hospital-based and primary care providers (PCPs) is needed for the provision of safe and effective care. PURPOSE OF THE STUDY: To evaluate timeliness, quality, and interventions to improve timeliness and quality of hospital discharge summaries. DATA SOURCES: PubMed, MEDLINE, EMBASE, CINAHL, Web of Science, and Scopus database published in English between January 2007 and February 2014 were searched. We also hand-searched bibliographies of relevant articles. STUDY SELECTION: Observational studies investigating transfer of information at hospital discharge (n = 7) and controlled studies evaluating interventions to improve timeliness and quality of discharge information (n = 12) were included. DATA EXTRACTION: We extracted data on availability, timeliness, and content of hospital discharge summaries and on the effectiveness of interventions targeting discharge summaries. Results of studies are presented narratively and using descriptive statistics. DATA SYNTHESIS: Across the studies, discharge summaries were completed within 48 hours in a median of 67% and were available to PCPs within 48 hours only 55% of the time. Most of the time, discharge summaries included demographics, primary diagnosis, hospital course, and discharge instructions. However, information was limited to pending test results (25%), diagnostic tests performed (60%), and postdischarge medications (78%). In 6 interventional studies, implementation of electronic discharge summaries was associated with improvement in timeliness but not quality. CONCLUSIONS: Delayed or insufficient transfer of discharge information between hospital-based providers and PCPs remains common. Creation of electronic discharge summaries seems to improve timeliness and availability but does not consistently improve quality.

OBJECTIVES: Treatment burden is the workload of healthcare for people with long-term conditions (LTC) and its impact on well-being. A method of measurement is required to identify those experiencing high burden and to measure intervention efficacy. Our aim was to identify, examine and appraise validated patient-reported measures (PRMs) of treatment burden in stroke. Here, stroke serves as an exemplar LTC of older adults. DESIGN: A systematic review of published studies that describe the development and validation of PRMs measuring treatment burden in stroke survivors. DATA SOURCES: We searched MEDLINE, Embase, CINAHL and PsycINFO electronic databases. ELIGIBILITY CRITERIA: Studies published between January 2000 and 12 April 2019 inclusive, in English language. No restrictions were set based on clinical setting or geographical location. DATA EXTRACTION AND SYNTHESIS: Screening, data extraction and quality appraisal were conducted by two independent reviewers. Content of the PRMs was compared with a published taxonomy of treatment burden. Quality appraisal was conducted using International Society for Quality of Life Research standards. RESULTS: From 3993 articles, 6 relevant PRMs were identified: 3 were stroke specific: The Satisfaction with Stroke Care questionnaire; The Stroke Patient-Reported Outcome Measure and The Barriers to Physical Activity after Stroke scale. Three were generic but validated in stroke: The WHO Quality of Life-100; The Patient's Questionnaire on Participation in Discharge Planning and The Chao Perception of Continuity scale. None comprehensively measured treatment burden. Examples of omitted burdens included developing coping strategies, managing finances and returning to driving. The most notable issue regarding quality appraisal was that three PRMs lacked any underpinning qualitative research relevant to the sample. CONCLUSION: There is a need to develop a comprehensive PRM of treatment burden for use in stroke, with potential for use in other older populations.

INTRODUCTION: There is a considerable implementation gap in managing early stage chronic kidney disease (CKD) in primary care despite the high prevalence and risk for increased morbidity and mortality associated with CKD. This systematic review aims to synthesise the evidence of efficacy of implementation interventions aimed at primary care practitioners (PCPs) to improve CKD identification and management. We further aim to describe the interventions' behavioural change components. METHODS AND ANALYSIS: We will conduct a systematic review of studies from 2000 to October 2017 that evaluate implementation interventions targeting PCPs and which include at least one clinically meaningful CKD outcome. We will search several electronic data bases and conduct reference mining of related systematic reviews and publications. An interdisciplinary team will independently and in duplicate, screen publications, extract data and assess the risk of bias. Clinical outcomes will include all clinically meaningful medical management outcomes relevant to CKD management in primary care such as blood pressure, chronic heart disease and diabetes target achievements. Quantitative evidence synthesis will be performed, where possible. Planned subgroup analyses include by (1) study design, (2) length of follow-up, (3) type of intervention, (4) type of implementation strategy, (5) whether a behavioural or implementation theory was used to guide study, (6) baseline CKD severity, (7) patient minority status, (8) study location and (9) academic setting or not. ETHICS AND DISSEMINATION: Approval by research ethics board is not required since the review will only include published and publicly accessible data. Review findings will inform a future trial of an intervention to promote uptake of CKD diagnosis and treatment guidelines in our primary care setting and the development of complementary tools to support its successful adoption and implementation. We will publish our findings in a peer-reviewed journal and develop accessible summaries of the results. PROSPERO REGISTRATION NUMBER: CRD42018102441.

BACKGROUND AND OBJECTIVES: Dialysis is a preference-sensitive decision where prognosis may play an important role. Although patients desire risk prediction, nephrologists are wary of sharing this information. We reviewed the performance of prognostic indices for patients starting dialysis to facilitate bedside translation. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Systematic review and meta-analysis following the PRISMA guidelines. We searched Ovid MEDLINE, Ovid Embase, Ovid Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus for eligible studies of patients starting dialysis published from inception to December 31, 2018. SELECTION CRITERIA: Articles describing validated prognostic indices predicting mortality at the start of dialysis. We excluded studies limited to prevalent dialysis patients, AKI and studies excluding mortality in the first 1-3 months. Two reviewers independently screened abstracts, performed full text assessment of inclusion criteria and extracted: study design, setting, population demographics, index performance and risk of bias. Pre-planned random effects meta-analysis was performed stratified by index and predictive window to reduce heterogeneity. RESULTS: Of 12,132 articles screened and 214 reviewed in full text, 36 studies were included describing 32 prognostic indices. Predictive windows ranged from 3 months to 10 years, cohort sizes from 46 to 52,796. Meta-analysis showed discrimination area under the curve (AUC) of 0.71 (95% confidence interval, 0.69 to 073) with high heterogeneity (I2=99.12). Meta-analysis by index showed highest AUC for The Obi, Ivory, and Charlson comorbidity index (CCI)=0.74, also CCI was the most commonly used (ten studies). Other commonly used indices were Kahn-Wright index (eight studies, AUC 0.68), Hemmelgarn modification of the CCI (six studies, AUC 0.66) and REIN index (five studies, AUC 0.69). Of the indices, ten have been validated externally, 16 internally and nine were pre-existing validated indices. Limitations include heterogeneity and exclusion of large cohort studies in prevalent patients. CONCLUSIONS: Several well validated indices with good discrimination are available for predicting survival at dialysis start.

Serum cystatin C has been proposed as a kidney biomarker to inform drug dosing. We conducted a systematic review to synthesize available data for the association between serum cystatin C and drug pharmacokinetics, dosing, and clinical outcomes in adults (≥18 years). PubMed, Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL, and Scopus were systematically searched from 1946 to September 2017 to identify candidate studies. Studies of cystatin C as a predictor for acute kidney injury or for management of contrast-associated acute kidney injury were excluded. Also, studies were excluded if drug concentrations were unavailable and if a reference standard for drug dosing (eg, serum creatinine) was not concurrently reported. The outcomes of interest included drug clearance (L/h), concentrations (mg/L), target level achievement (%), therapeutic failure (%), and drug toxicity (%). We included 28 articles that evaluated 16 different medications in 3455 participants. Vancomycin was the most well-studied drug. Overall, cystatin C-based estimated glomerular filtration rate (eGFRCystatin C) was more predictive of drug levels and drug clearance than eGFRCreatinine. In only one study were target attainment and outcomes compared between 2 drug-dosing regimens, one based on eGFRCreatinine-Cystatin C and one dosed with the Cockcroft-Gault creatinine clearance equation. Compared with eGFRCreatinine, use of eGFRCystatin C to predict elimination of medications via the kidney was as accurate, if not superior, in most studies, but infrequently were data on target attainment or clinical outcomes reported. Drug-specific dosing protocols that use cystatin C to estimate kidney function should be tested for clinical application.

BACKGROUND & AIMS: Studies have reported a lack of association between improvements in gastric emptying (GE) and upper gastrointestinal (UGI) symptoms with promotility drugs. However, GE test methods were suboptimal in some studies. We assessed improvements in GE and UGI symptoms in patients given promotility agents in studies with optimal or moderate test methods (scintigraphy or breath test, solid meal, >2 hours duration) compared to studies with suboptimal GE test methods. METHODS: With an expert librarian, we completed an extensive search of publications in the Ovid MEDLINE (1946 to present), EMBASE (1988 to January 2018), and EBM Reviews Cochrane Central Register of Controlled Trials, without restrictions on language or year. Two independent reviewers evaluated the following inclusion criteria: randomized, blinded, parallel, or crossover trials of 5HT4 agonists, D2 receptor antagonist, or ghrelin agonists; trials that measured change in GE (T1/2) or composite UGI symptoms; trials of patients with functional dyspepsia and gastroparesis; and trials of GE test methods. Standardized mean differences (units expressed as SD) were used to standardize symptom assessments that were not uniform across studies. Random effects model was used to analyze data and meta-regression was used to evaluate the association between change in GE and UGI symptoms. RESULTS: Of 899 studies considered, 22 studies assessed change in GE; 23 evaluated UGI symptoms; and 14 evaluated GE and UGI symptoms. Promotility agents significantly accelerated GE (T1/2) in all studies (mean reduction in T1/2, 16.3 minutes; 95% confidence interval, -22.1 to -10.6 minutes) and in studies that used optimal GE test methods (mean reduction in T1/2, 23.6 minutes; 95% confidence interval, -32.3 to -14.9 minutes). Promotility agents also significantly reduced UGI symptoms (mean reduction, 0.25 SD; 95% confidence interval, -0.37 to -0.13 SD). Meta-regression found no significant association between change in GE and UGI symptoms. However, when only studies with optimal GE test methods were evaluated, there was a significant positive association between improvement in GE and UGI symptoms (P = .02). CONCLUSIONS: In a meta-analysis of published trials, we found promotility agents to significantly accelerate GE (when optimal test methods were used) and to produce significant improvements in UGI symptoms.
