RESUMO

Importance: Dental caries is common in children and adolescents aged 5 to 17 years and potentially amenable to primary care screening and prevention. Objective: To systematically review the evidence on primary care screening and prevention of dental caries in children and adolescents aged 5 to 17 years to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews (to October 3, 2022); surveillance through July 21, 2023. Study Selection: Diagnostic accuracy of primary care screening instruments and oral examination; randomized and nonrandomized trials of screening and preventive interventions and systematic reviews of such studies; cohort studies on primary care oral health screening and preventive intervention harms. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Random-effects meta-analysis was performed for fluoride supplements and xylitol; for other preventive interventions, pooled estimates were used from good-quality systematic reviews. Main Outcomes and Measures: Dental caries, morbidity, functional status, quality of life, harms; diagnostic test accuracy. Results: Three systematic reviews (total 20 684 participants) and 19 randomized clinical trials, 3 nonrandomized trials, and 1 observational study (total 15 026 participants) were included. No study compared screening vs no screening. When administered by dental professionals or in school settings, fluoride supplements compared with placebo or no intervention were associated with decreased change from baseline in the number of decayed, missing, or filled permanent teeth (DMFT index) or decayed or filled permanent teeth (DFT index) (mean difference, -0.73 [95% CI, -1.30 to -0.19]) at 1.5 to 3 years (6 trials; n = 1395). Fluoride gels were associated with a DMFT- or DFT-prevented fraction of 0.18 (95% CI, 0.09-0.27) at outcomes closest to 3 years (4 trials; n = 1525), fluoride varnish was associated with a DMFT- or DFT-prevented fraction of 0.44 (95% CI, 0.11-0.76) at 1 to 4.5 years (5 trials; n = 3902), and resin-based sealants were associated with decreased risk of carious first molars (odds ratio, 0.21 [95% CI, 0.16-0.28]) at 48 to 54 months (4 trials; n = 440). No trial evaluated primary care counseling or dental referral. Evidence on screening accuracy, silver diamine fluoride, xylitol, and harms was very limited, although serious harms were not reported. Conclusions and Relevance: Administration of fluoride supplements, fluoride gels, varnish, and sealants in dental or school settings improved caries outcomes. Research is needed on the effectiveness of oral health preventive interventions in primary care settings and to determine the benefits and harms of screening.

RESUMO

Importance: Dental caries and periodontal disease are common adult oral health conditions and potentially amenable to primary care screening and prevention. Objective: To systematically review the evidence on primary care screening and prevention of dental caries and periodontal disease in adults to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews (to October 3, 2022); surveillance through July 21, 2023. Study Selection: Diagnostic accuracy studies of primary care screening instruments and oral examination; randomized and nonrandomized trials of screening and preventive interventions; cohort studies on primary care oral health screening and preventive intervention harms. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Diagnostic accuracy data were pooled using a bivariate mixed-effects binary regression model. Main Outcomes and Measures: Dental caries, periodontal disease, morbidity, quality of life, harms; and diagnostic test accuracy. Results: Five randomized clinical trials, 5 nonrandomized trials, and 6 observational studies (total 3300 participants) were included. One poor-quality trial (n = 477) found no difference between oral health screening during pregnancy vs no screening in caries, periodontal disease, or birth outcomes. One study (n = 86) found oral health examination by 2 primary care clinicians associated with low sensitivity (0.42 and 0.56) and high specificity (0.84 and 0.87) for periodontal disease and with variable sensitivity (0.33 and 0.83) and high specificity (0.80 and 0.93) for dental caries. Four studies (n = 965) found screening questionnaires associated with a pooled sensitivity of 0.72 (95% CI, 0.57-0.83) and specificity of 0.74 (95% CI, 0.66-0.82) for periodontal disease. For preventive interventions no study evaluated primary care counseling or dental referral, and evidence from 2 poor-quality trials (n = 178) of sealants, and 1 fair-quality and 4 poor-quality trials (n = 971) of topical fluorides, was insufficient. Three fair-quality trials (n = 590) of persons with mean age 72 to 80 years found silver diamine fluoride solution associated with fewer new root caries lesions or fillings vs placebo (mean reduction, -0.33 to -1.3) and decreased likelihood of new root caries lesion (2 trials; adjusted odds ratio, 0.4 [95% CI, 0.3-0.7]). No trial evaluated primary care-administered preventive interventions. Conclusions and Relevance: Screening questionnaires were associated with moderate diagnostic accuracy for periodontal disease. Research is needed to determine benefits and harms of oral health primary care screening and preventive interventions.

RESUMO

PURPOSE: In 2019 the American Urological Association (AUA) released the evidence-based guideline "Recurrent Uncomplicated Urinary Tract Infections in Women: AUA/CUA/SUFU Guideline." Information supporting the guideline came from a 2019 systematic evidence review prepared for the AUA by the Pacific Northwest Evidence-based Practice Center (EPC). The AUA used evidence found for 11 Key Questions (Appendix C) in the EPC's report to derive 16 Guideline Statements. In 2021 the EPC conducted an Update Literature Review (ULR) assessing abstracts from new studies published since the 2019 systematic review. The AUA asked the EPC to further assess a subset of studies included in the ULR report, to support potential changes to the 2019 guideline. MATERIALS/METHODS: A systematic-review utilized research from the Oregon Health & Science University. Pacific Northwest EPC was used to update the 2019 AUA Guideline on rUTI in women with new evidence published through 2021. RESULTS: Updates were made to reflect changes in literature since 2019. Updates include recent publications on antibiotic prophylaxis, non-antibiotic prophylaxis, and estrogen therapy. CONCLUSION: The presence of rUTI is crucial to the health of patients and its effects must be considered for the welfare of society. This document will undergo updating as the knowledge regarding current treatments and future treatment options continues to expand. .

RESUMO

OBJECTIVE: The authors of this systematic review (SR) sought to provide evidence for effects of commonly used psychosocial interventions on several outcomes among adults with schizophrenia. METHODS: MEDLINE, the Cochrane Library, and PsycINFO databases were searched through July 2020. Eligible studies were SRs and trials of at least 12 weeks duration and with ≥50 participants that compared psychosocial interventions with treatment as usual among adults with schizophrenia. Study design, year, setting, country, sample size, eligibility criteria, population, clinical and intervention characteristics, results, and funding source were extracted, along with quality criteria. The evidence was evaluated on quality and strength of evidence stratified by intervention area and outcome, according to the Evidence-Based Practice Centers Methods Guide of the Agency for Healthcare Research and Quality. RESULTS: Nine SRs and 30 trials (N=23,921 patients) in 11 intervention areas were included. Trials were mostly of fair quality and had low-to-moderate strength of evidence. Compared with treatment as usual, most psychosocial interventions were more effective in improving intervention-targeted outcomes, including core illness symptoms. Compared with treatment as usual, assertive community treatment, cognitive-behavioral therapy (CBT), family interventions, psychoeducation, social skills training, supported employment, and early interventions for first-episode psychosis (FEP) improved various functional outcomes. CBT and early interventions for FEP improved quality of life. Family interventions, psychoeducation, illness self-management, and early interventions for FEP reduced relapse. CONCLUSIONS: Compared with treatment as usual, most psychosocial interventions improved functional outcomes, quality of life, and core illness symptoms, and several reduced relapse frequency among adults with schizophrenia.

RESUMO

OBJECTIVE: To understand the benefits and harms of physical activity in people who may require a wheelchair with a focus on people with multiple sclerosis (MS), cerebral palsy (CP), and spinal cord injury (SCI). DATA SOURCES: Searches were conducted in MEDLINE, Cumulative Index to Nursing and Allied Health, PsycINFO, Cochrane CENTRAL, and Embase (January 2008 through November 2020). STUDY SELECTION: Randomized controlled trials, nonrandomized trials, and cohort studies of observed physical activity (at least 10 sessions on 10 days) in participants with MS, CP, and SCI. DATA EXTRACTION: We conducted dual data abstraction, quality assessment, and strength of evidence. Measures of physical functioning are reported individually where sufficient data exist and grouped as "function" where data are scant. DATA SYNTHESIS: No studies provided evidence for prevention of cardiovascular conditions, development of diabetes, or obesity. Among 168 included studies, 44% enrolled participants with MS (38% CP, 18% SCI). Studies in MS found walking ability may be improved with treadmill training and multimodal exercises; function may be improved with treadmill, balance exercises, and motion gaming; balance is likely improved with balance exercises and may be improved with aquatic exercises, robot-assisted gait training (RAGT), motion gaming, and multimodal exercises; activities of daily living (ADL), female sexual function, and spasticity may be improved with aquatic therapy; sleep may be improved with aerobic exercises and aerobic fitness with multimodal exercises. In CP, balance may be improved with hippotherapy and motion gaming; function may be improved with cycling, treadmill, and hippotherapy. In SCI, ADL may be improved with RAGT. CONCLUSIONS: Depending on population and type of exercise, physical activity was associated with improvements in walking, function, balance, depression, sleep, ADL, spasticity, female sexual function, and aerobic capacity. Few harms of physical activity were reported in studies. Future studies are needed to address evidence gaps and to confirm findings.

RESUMO

The prevalence of major unipolar depression in children and adolescents is increasing in the United States. In 2016, approximately 5% of 12-year-olds and 17% of 17-year-olds reported experiencing a major depressive episode in the previous 12 months. Screening for depression in adolescents 12 years and older should be conducted annually using a validated instrument, such as the Patient Health Questionnaire-9: Modified for Teens. If the diagnosis is confirmed, treatment should be initiated for persistent, moderate, and severe depression. Active support and monitoring may be sufficient for mild, self-limited depression. For more severe depression, evidence indicates greater response to treatment when psychotherapy (e.g., cognitive behavior therapy) and an antidepressant are used concurrently, compared with either treatment alone. Fluoxetine and escitalopram are the only antidepressants approved by the U.S. Food and Drug Administration for treatment of depression in children and adolescents. Fluoxetine may be used in patients older than eight years, and escitalopram may be used in patients 12 years and older. Monitoring for suicidality is necessary in children and adolescents receiving pharmacotherapy, with frequency of monitoring based on each patient's individual risk. The decision to modify treatment (add, increase, change the medication or add psychotherapy) should be made after about four to eight weeks. Consultation with or referral to a mental health subspecialist is warranted if symptoms worsen or do not improve despite treatment and for those who become a risk to themselves or others.

RESUMO

INTRODUCTION: Overactive bladder (OAB) is a common condition, increasing with age and affecting quality of life. While numerous OAB drugs are available, persistence is low. We evaluated evidence published since 2012 to determine if newer drugs provided better efficacy and harm profiles. METHODS: We searched MEDLINE and the Cochrane Library from 2012 to September 2018 using terms for included drugs and requested information from manufacturers of included drugs. We performed dual review of all systematic review processes, evaluated study quality, and conducted meta-analyses using random effects models. RESULTS: In addition to 31 older studies, we included 20 trials published since 2012 (N = 16,478; 4 good, 11 fair, and 5 poor quality). Where statistical differences were found, they were clinically small (reductions of < 0.5 episodes/day). Solifenacin plus mirabegron improved efficacy outcomes over monotherapy with either drug, but significantly increased constipation compared with solifenacin and dry mouth compared with mirabegron. Solifenacin reduced incontinence over mirabegron and tolterodine and urgency episodes over tolterodine. Mirabegron did not differ from tolterodine in efficacy but had significantly lower incidence of dry mouth than solifenacin or tolterodine. Fesoterodine showed significant improvements but also anticholinergic effects vs. tolterodine. Oxybutynin, solifenacin, and tolterodine had similar efficacy, but dry mouth led to greater discontinuation with oxybutynin. Blurred vision, cardiac arrhythmia, and dizziness were uncommon. CONCLUSION: New evidence confirms small, but clinically uncertain, differences among monotherapies and also between combination and monotherapy, regardless of statistical significance. While drugs mainly differed in incidence of dry mouth or constipation, none provided improved efficacy without increased harms.

RESUMO

Importance: Prenatal screening for HIV can inform use of interventions to reduce the risk of mother-to-child transmission. The US Preventive Services Task Force (USPSTF) previously found strong evidence that prenatal HIV screening reduced risk of mother-to-child transmission. The previous evidence review was conducted in 2012. Objective: To update the 2012 review on prenatal HIV screening to inform the USPSTF. Data Sources: Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews from 2012 to June 2018, with surveillance through January 2019. Study Selection: Pregnant persons 13 years and older; randomized clinical trials and cohort studies of screening vs no screening; risk of mother-to-child transmission or maternal or infant harms associated with antiretroviral therapy (ART) during pregnancy; screening yield at different intervals or in different risk groups. Data Extraction and Synthesis: One investigator abstracted data; a second checked accuracy. Two investigators independently rated study quality. Main Outcomes and Measures: Mother-to-child transmission; harms of screening and treatment; screening yield. Results: Sixty-two studies were included in this review, including 29 new studies. There remains no direct evidence on effects of prenatal screening vs no screening on risk of mother-to-child HIV transmission, maternal or infant clinical outcomes, or the yield of repeat or alternative screening strategies. New evidence confirms that combination ART is highly effective at reducing the risk of mother-to-child transmission, with some new cohort studies reporting rates of mother-to-child transmission less than 1% when combination ART was started early in pregnancy (when begun in first trimester, 0%-0.4%; when begun after first trimester, or at any time if timing of ART initiation not reported, 0.4%-2.8%). New evidence on harms of ART was also largely consistent with the previous review. Evidence from primarily observational studies found prenatal combination ART with a boosted protease inhibitor associated with increased risk of preterm delivery (range, 14.4%-26.1%). For other birth outcomes (low birth weight, small for gestational age, stillbirth, birth defects, neonatal death), results were mixed and depended on the specific antiretroviral drug or drug regimen given and timing of prenatal therapy. Conclusions and Relevance: Combination ART was highly effective at reducing risk of mother-to-child HIV transmission. Use of certain ART regimens during pregnancy was associated with increased risk of harms that may be mitigated by selection of ART regimen. The 2012 review found that avoidance of breastfeeding and cesarean delivery in women with viremia also reduced risk of transmission and that prenatal screening accurately diagnosed HIV infection.

RESUMO

INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been commonly used to treat endodontic postoperative pain. The purpose of this study was to address the following Population, Intervention, Comparator, Outcome, Timing, Study design and setting question: in patients with preoperative pain who undergo initial orthograde endodontic treatment, what is the comparative efficacy of NSAIDS compared with non-narcotic analgesics or placebo in reducing postoperative pain and the incidence of adverse events. METHODS: Ovid MEDLINE (1946-December 15, 2015), the Cochrane Database of Systematic Reviews (2005-December 15, 2015), and the Cochrane Central Register of Controlled Trials (to December 15, 2015) were searched using included drugs, indications, and study designs as search terms. Hand searches in texts were also conducted. Two independent reviewers assessed eligibility for inclusion, extracted data, and assessed quality using the risk of bias tool. L'Abbe plots were used for qualitative review. Where applicable, meta-analysis was conducted on the pooled effect size (ES). RESULTS: Two thousand two hundred eighty-four studies were identified through the database searches; 405 full-text articles were assessed. Fifteen articles met the inclusion criteria; qualitative analysis revealed all studies had a moderate to high risk of bias. Ibuprofen was the most studied NSAID. The L'Abbe plots showed that NSAIDS are effective at relieving postoperative endodontic pain overall. Meta-analysis showed that ibuprofen 600 mg is more effective than placebo at 6 hours postoperatively (ES = 10.50, P = .037), and ibuprofen 600 mg + acetaminophen 1000 mg combination is more effective than placebo (ES = 34.89, P = .000) but not significantly different than ibuprofen (ES = 13.94, P = .317). Five studies reported patients experiencing adverse events such as drowsiness, dizziness, nausea, and emesis; 2 studies reported that patients experienced no adverse events. CONCLUSIONS: A combination of ibuprofen 600 mg and acetaminophen 1000 mg is more effective than placebo but not significantly different than ibuprofen 600 mg at 6 hours postoperatively. Ibuprofen 600 mg is more effective than placebo at 6 hours postoperatively; however, there are insufficient data to recommend the most effective NSAID, dose amount, or dose interval for the relief of postoperative endodontic pain of longer duration in patients with preoperative pain.

RESUMO

There is uncertainty regarding the use of bladder-sparing alternatives to standard radical cystectomy, optimal lymph node dissection techniques, and optimal chemotherapeutic regimens. This study was conducted to systematically review the benefits and harms of bladder-sparing therapies, lymph node dissection, and systemic chemotherapy for patients with clinically localized muscle-invasive bladder cancer. Systematic literature searches of MEDLINE (from 1990 through October 2014), the Cochrane databases, reference lists, and the ClinicalTrials.gov Web site were performed. A total of 41 articles were selected for review. Bladder-sparing therapies were found to be associated with worse survival compared with radical cystectomy, although the studies had serious methodological shortcomings, findings were inconsistent, and only a few studies evaluated currently recommended techniques. More extensive lymph node dissection might be more effective than less extensive dissection at improving survival and decreasing local disease recurrence, but there were methodological shortcomings and some inconsistency. Six randomized trials found cisplatin-based combination neoadjuvant chemotherapy to be associated with a decreased mortality risk versus cystectomy alone. Four randomized trials found adjuvant chemotherapy to be associated with decreased mortality versus cystectomy alone, but none of these trials reported a statistically significant effect. There was insufficient evidence to determine optimal chemotherapeutic regimens.

RESUMO

BACKGROUND: Seventeen of 172 included studies in a recent systematic review of blood tests for hepatic fibrosis or cirrhosis reported diagnostic accuracy results discordant from 2 × 2 tables, and 60 studies reported inadequate data to construct 2 × 2 tables. This study explores the yield of contacting authors of diagnostic accuracy studies and impact on the systematic review findings. METHODS: Sixty-six corresponding authors were sent letters requesting additional information or clarification of data from 77 studies. Data received from the authors were synthesized with data included in the previous review, and diagnostic accuracy sensitivities, specificities, and positive and likelihood ratios were recalculated. RESULTS: Of the 66 authors, 68% were successfully contacted and 42% provided additional data for 29 out of 77 studies (38%). All authors who provided data at all did so by the third emailed request (ten authors provided data after one request). Authors of more recent studies were more likely to be located and provide data compared to authors of older studies. The effects of requests for additional data on the conclusions regarding the utility of blood tests to identify patients with clinically significant fibrosis or cirrhosis were generally small for ten out of 12 tests. Additional data resulted in reclassification (using median likelihood ratio estimates) from less useful to moderately useful or vice versa for the remaining two blood tests and enabled the calculation of an estimate for a third blood test for which previously the data had been insufficient to do so. We did not identify a clear pattern for the directional impact of additional data on estimates of diagnostic accuracy. CONCLUSIONS: We successfully contacted and received results from 42% of authors who provided data for 38% of included studies. Contacting authors of studies evaluating the diagnostic accuracy of serum biomarkers for hepatic fibrosis and cirrhosis in hepatitis C patients impacted conclusions regarding diagnostic utility for two blood tests and enabled the calculation of an estimate for a third blood test. Despite relatively extensive efforts, we were unable to obtain data to resolve discrepancies or complete 2 × 2 tables for 62% of studies.

RESUMO

BACKGROUND: In 2004, the U.S. Preventive Services Task Force determined that evidence was insufficient to recommend behavioral interventions and counseling to prevent child abuse and neglect. PURPOSE: To review new evidence on the effectiveness of behavioral interventions and counseling in health care settings for reducing child abuse and neglect and related health outcomes, as well as adverse effects of interventions. DATA SOURCES: MEDLINE and PsycINFO (January 2002 to June 2012), Cochrane Central Register of Controlled Trials and Cochrane Database of Systematic Reviews (through the second quarter of 2012), Scopus, and reference lists. STUDY SELECTION: English-language trials of the effectiveness of behavioral interventions and counseling and studies of any design about adverse effects. DATA EXTRACTION: Investigators extracted data about study populations, designs, and outcomes and rated study quality using established criteria. DATA SYNTHESIS: Eleven fair-quality randomized trials of interventions and no studies of adverse effects met inclusion criteria. A trial of risk assessment and interventions for abuse and neglect in pediatric clinics for families with children aged 5 years or younger indicated reduced physical assault, Child Protective Services (CPS) reports, nonadherence to medical care, and immunization delay among screened children. Ten trials of early childhood home visitation reported reduced CPS reports, emergency department visits, hospitalizations, and self-reports of abuse and improved adherence to immunizations and well-child care, although results were inconsistent. LIMITATION: Trials were limited by heterogeneity, low adherence, high loss to follow-up, and lack of standardized measures. CONCLUSION: Risk assessment and behavioral interventions in pediatric clinics reduced abuse and neglect outcomes for young children. Early childhood home visitation also reduced abuse and neglect, but results were inconsistent. Additional research on interventions to prevent child abuse and neglect is needed.

RESUMO

BACKGROUND: Conflict of interest (COI) is an important potential source of bias in the development of clinical practice guidelines (CPGs) and high rates of COI among guideline authors have been reported in the past. Our objective was to report current rates of disclosure and specific author COI across a broad range of CPGs and to examine whether CPG characteristics were associated with the presence of disclosures and of conflicts. METHODS AND FINDINGS: We selected a random sample of 250 CPGs listed in the National Guideline Clearinghouse on November 22, 2010, representing approximately a 10% sample of guidelines listed in the NGC on that date. We abstracted information on author COI from each CPG and examined predictors of the disclosures and COI using a logistic generalized estimating equation regression model. 87% of organizations developing guidelines had a CPG-specific policy, however, 40% of CPGs did not indicate that they had collected disclosures from guideline authors. In addition, 42% of organizations that did collect author disclosures did not have those disclosures available in the public domain. Of CPGs where we had disclosures for all authors, 60% had one or more authors with a conflict. On average, 28% of the authors of CPGs with available disclosures had a COI. Guidelines that were published in journals with an impact factor greater than 5.0 were more likely to have one or more authors with a COI than guidelines not published in journals. CONCLUSIONS: Rates of disclosure of author COI and the public availability of that information are unacceptably low, however rates of COI among guideline authors may have decreased in recent years. Continued efforts are needed to establish and enforce optimal COI policies in clinical practice guideline development in order to minimize the risk of bias associated with those conflicts.
