RESUMO

BACKGROUND: Women with substance-use issues are overrepresented in prison. Research on women's recidivism often focuses on offending behaviour rather than the health and social circumstances women are experiencing when reimprisonment occurs. This study examines the relationship between social determinants of health (SDOH), mental health, substance-use and recidivism among women exiting prison with histories of substance-use. METHODS: A retrospective cohort study of women exiting prison who completed the transitional support programme "Connections" between 2008 and 2018. Recidivism was measured up to two years post-release. Women's support needs were measured at baseline (4 weeks pre-release) and follow-up (four weeks post-release). Ongoing needs in relation to well-established SDOH were calculated if: (1) at baseline women were identified as having a re-entry need with housing, employment, finances, education, domestic violence, child-custody and social support and (2) at follow-up women reported still needing help in that area. Women's self-reported substance-use and mental health since release were captured at follow-up. Descriptive statistics were calculated for all measures. Associations between SDOH, mental health, substance-use and recidivism were estimated by multiple logistic regression, adjusting for potential confounders. We also evaluated the mediating effects of mental health on the relationship between SDOH and substance-use. RESULTS: Substance-use was associated with increased odds of recidivism (adjusted odds ratio (AOR) 1.8, 95% confidence interval (CI) 1.1-2.9; p = 0.02). Poor mental health (AOR 2.9, 95% CI 1.9-4.6; p = < 0.01), ongoing social support (AOR 3.0, 95% CI 1.9-5.0; p = < 0.01), child-custody (AOR 1.9, 95% CI 1.0-3.3 p = 0.04), financial (AOR 2.0, 95% CI 1.3-3.2; p = < 0.01) and housing (AOR 1.8, 95% CI 1.1-2.9; p = 0.02) needs were individually associated with increased odds of substance-use. Mediation analysis found mental health fully mediated the effects of ongoing housing (beta efficiency (b) = - 033, standard error (SE) 0.01; p = 0.05), financial (b = 0.15, SE 0.07; p = 0.05), child-custody (b = 0.18, SE 0.01; p = 0.05) and social support (b = 0.36, SE 0.1; p = 0.05) needs onto substance-use, and partially mediated the effects of domestic violence (b = 0.57, SE 0.23; p = 0.05) onto substance-use. CONCLUSION: This study underscores the critical importance of addressing the interplay between SDOH, mental health, substance-use and recidivism. An approach that targets SDOH holds the potential for reducing mental distress and substance-use, and related recidivism.

RESUMO

BACKGROUND: The impact of comorbid disease states on the development of atrial and ventricular arrhythmias in patients with hypertrophic cardiomyopathy (HCM) remains unresolved. OBJECTIVE: Evaluate the association of comorbidities linked to arrhythmias in other cardiovascular diseases (e.g., obesity, systemic hypertension, diabetes, obstructive sleep apnea, renal disorders, tobacco, and alcohol use) to atrial fibrillation (AF) and sudden cardiac death (SCD) events in a large cohort of HCM patients. METHODS: A total  of 2269 patients, 54 ± 15 years of age, 1392 males, were evaluated at the Tufts HCM Institute between 2004 and 2018 and followed for an average of 4 ± 3 years for new-onset clinical AF and SCD events (appropriate defibrillation for ventricular tachyarrhythmias, resuscitated cardiac arrest, or SCD). RESULTS: One or more comorbidity was present in 75% of HCM patients, including 50% with ≥2 comorbidities, most commonly obesity (body mass index [BMI] ≥ 30 kg/m2 ) in 43%. New-onset atrial fibrillation developed in 11% of our cohort (2.6%/year). On univariate analysis, obesity was associated with a 1.7-fold increased risk for AF (p = .03) with 12% of obese patients developing AF (3.3%/year) as compared to 7% of patients with BMI < 25 kg/m2 (1.6%/year; p = .006). On multivariate analysis, age and LA transverse dimension emerged as the only variables predictive of AF. Comorbidities, including obesity, were not independently associated with AF development (p > .10 for each). SCD events occurred in 3.3% of patients (0.8%/year) and neither obesity nor other comorbidities were associated with increased risk for SCD (p > .10 for each). CONCLUSIONS: In adult HCM patients comorbidities do not appear to impact AF or SCD risk. Therefore, for most patients with HCM, adverse disease related events of AF and SCD appear to be primarily driven by underlying left ventricular and atrial myopathy as opposed to comorbidities.

RESUMO

Myocardial hypertrophy is an independent risk factor for heart failure (HF), yet the mechanisms underlying pathological cardiomyocyte growth are incompletely understood. The c-Jun NH2-terminal kinase (JNK) signaling cascade modulates cardiac hypertrophic remodeling, but the upstream factors regulating myocardial JNK activity remain unclear. In this study, we sought to identify JNK-activating molecules as novel regulators of cardiac remodeling in HF. We investigated mixed lineage kinase-3 (MLK3), a master regulator of upstream JNK-activating kinases, whose role in the remodeling process had not previously been studied. We observed increased MLK3 protein expression in myocardium from patients with nonischemic and hypertrophic cardiomyopathy and in hearts of mice subjected to transverse aortic constriction (TAC). Mice with genetic deletion of MLK3 (MLK3-/-) exhibited baseline cardiac hypertrophy with preserved cardiac function. MLK3-/- mice subjected to chronic left ventricular (LV) pressure overload (TAC, 4 wk) developed worsened cardiac dysfunction and increased LV chamber size compared with MLK3+/+ littermates ( n = 8). LV mass, pathological markers of hypertrophy ( Nppa, Nppb), and cardiomyocyte size were elevated in MLK3-/- TAC hearts. Phosphorylation of JNK, but not other MAPK pathways, was selectively impaired in MLK3-/- TAC hearts. In adult rat cardiomyocytes, pharmacological MLK3 kinase inhibition using URMC-099 blocked JNK phosphorylation induced by neurohormonal agents and oxidants. Sustained URMC-099 exposure induced cardiomyocyte hypertrophy. These data demonstrate that MLK3 prevents adverse cardiac remodeling in the setting of pressure overload. Mechanistically, MLK3 activates JNK, which in turn opposes cardiomyocyte hypertrophy. These results support modulation of MLK3 as a potential therapeutic approach in HF. NEW & NOTEWORTHY Here, we identified a role for mixed lineage kinase-3 (MLK3) as a novel antihypertrophic and antiremodeling molecule in response to cardiac pressure overload. MLK3 regulates phosphorylation of the stress-responsive JNK kinase in response to pressure overload and in cultured cardiomyocytes stimulated with hypertrophic agonists and oxidants. This study reveals MLK3-JNK signaling as a novel cardioprotective signaling axis in the setting of pressure overload.

RESUMO

STUDY OBJECTIVE: Randomized controlled trials govern evidence-based clinical practice, and it is therefore critical that their results be robust. We aim to investigate the fragility of randomized controlled trials in emergency medicine by determining how often significance would be nullified with small changes in outcomes using the fragility index. METHODS: We conducted a methodological systematic review of randomized controlled trials in emergency medicine published in the top 10 general medicine journals and the top 10 emergency medicine journals. Inclusion criteria required that trials be emergency medicine studies structured with a 2-arm or 2-by-2 factorial design and report at least 1 statistically significant dichotomous outcome. RESULTS: A total of 180 trials met inclusion criteria. The median fragility index across all trials in emergency medicine was 4 (interquartile range [IQR] 2 to 10) and the median sample size was 140 (IQR 69.5 to 286). For trials from general medicine journals (n=32), the median fragility index was 9 (IQR 4 to 16.5) and the median sample size was 415.5 (IQR 219.5 to 901); for trials from emergency medicine journals (n=148), the median fragility index was 4 (IQR 1 to 9) and the median sample size was 119 (IQR 60 to 227.25). One third of all trials (62/180) had a loss to follow-up that was greater than or equal to the fragility index. There was a modest correlation between fragility index and total number of events (r=0.36; 95% confidence interval [CI] 0.23 to 0.48) and a weak correlation between fragility index and total sample size (r=0.26; 95% CI 0.12 to 0.39). There was no correlation between fragility index and either P value (r=-0.14; 95% CI -0.28 to -0.006) or Science Citation Index (r=0.07; 95% CI -0.08 to 0.22). CONCLUSION: The statistical significance of the results of randomized controlled trials in emergency medicine was often contingent on a small number of events. Until frequentist interpretation of clinical trials is replaced with Bayesian analysis, the fragility index may have utility as a tool to aid clinicians in assessing the robustness of randomized controlled trials in emergency medicine when considered in conjunction with the fragility quotient and other reported metrics.

RESUMO

Background Anal cancer disproportionately affects people with HIV infection, especially gay and bisexual men (GBM). The awareness and understanding of human papillomavirus (HPV) and anal cancer in a community-based sample of people living with HIV and GBM was explored to inform future evidence-based public health interventions. METHODS: Following consultation with affected communities and relevant healthcare professionals, a questionnaire was developed that assessed knowledge, understanding and experience of anal HPV, HPV vaccination, screening and perceived personal risk of anal cancer. Participants were recruited through HIV community and GBM organisations and anonymously completed the questionnaire online. RESULTS: Of 1660 questionnaires returned, 1574 were analysed from men, of whom 1535 (97.5%) identified as GBM and 15.7% reported being HIV-positive. Most (51.8%) of the HIV-positive men and 68.1% of HIV-negative or unknown men thought their risk of anal cancer was the same, or lower, than that of the general population. Only a small minority (12.5%) reported ever having talked to their doctor about anal HPV and/or anal cancer and 11.6% reported ever having had an anal cancer examination. Less than one-third (31.5%) had heard of HPV vaccination and only 2.9% of men recollected receiving HPV vaccination. CONCLUSIONS: Knowledge and awareness of anal cancer was generally poor in a sample of HIV-positive and HIV-negative GBM. Specific information targeted at these people could potentially raise awareness, leading to earlier diagnosis, reduced burden of disease among GBM and less demands on the healthcare system. Young GBM might benefit from education regarding the importance of HPV vaccination.

RESUMO

BACKGROUND: Advances in medical treatment for HIV are driving major changes in HIV policy and practice, including the encouragement of intake and adherence to HIV antiretroviral treatment (ART) by people living with HIV (PLHIV) for both personal and public health benefits. However, there is increasing recognition that achieving these goals will require a concurrent focus on the broader psychological and social wellbeing of PLHIV. Increasingly calls are being been made to incorporate a stronger focus on quality of life (QoL) of PLHIV into HIV prevention policy. In order to achieve this goal, HIV community, support and healthcare services need a valid, short and practical way to evaluate QoL of PLHIV accessing their programs. Current QoL measures are either long, complex, restricted in their use, or expensive. To address these shortcomings, the PozQoL study aimed to develop, test and validate a short and freely available scale assessing QoL among PLHIV. METHODS: Drawing on a literature review, the prioritisation of domains and development of the initial pool of items was conducted in consultation with PLHIV community organisations in Australia. The items covered health concerns, psychological, social, and functional wellbeing. Testing involved a baseline and a follow-up survey of 465 adult Australians living with HIV. Participants were recruited through social media and various community organizations nationwide. The survey included the pilot PozQoL scale and other validated measures of health and wellbeing. RESULTS: Guided by an Exploratory Factor Analysis and conceptual considerations, a 13-item scale was developed. The PozQoL scale demonstrated high levels of fit in a Confirmatory Factor Analysis, very good internal consistency, test-retest reliability, and concurrent validity with other measures that approximated different aspects of QoL. CONCLUSION: The PozQoL scale has been tested in a diverse sample of adult PLHIV living in Australia, demonstrating very good reliability and validity. The insights from PLHIV and other stakeholders supported the balancing of statistical rigour and conceptual accuracy. The scale is now ready to be implemented and field-tested across a range of community, support and healthcare programs for PLHIV. This will make a significant contribution to the evaluation and enhancement of programs for PLHIV.

RESUMO

PURPOSE: An estimated 85% of research is of limited value or wasted because the wrong research questions are addressed. We sought to identify research gaps using American Academy of Orthopaedic Surgeon (AAOS) clinical practice guidelines Treatment of Osteoarthritis of the Knee and Surgical Management of Osteoarthritis of the Knee. Using these recommendations, we conducted searches of ClinicalTrials.gov to discover the extent to which new and ongoing research addresses areas of deficiency. METHODS: For each recommendation in the AAOS guidelines, we created participants, intervention, comparator, outcomes questions, and search strings using a systematic process. Searches were then conducted of ClinicalTrials.gov to locate relevant studies. RESULTS: Our searches of ClinicalTrials.gov returned 945 studies for surgical and 1416 for non-surgical management of osteoarthritis. Of the 945 studies returned using our search string for surgical trials, 186 (20%) were relevant to 30 (79%) of the 38 recommendations made within the surgical management guideline. Of the 1416 studies returned using our search for non-surgical trials, 360 (25%) were relevant to 16 (89%) of the 18 recommendations made within the conservative management guideline. CONCLUSIONS: The development of clinical practice guidelines is a unique opportunity to simultaneously redefine day-to-day decision-making and provide a critical analysis of the status of the literature. Upon our search of the literature since the guidelines introduction, we have found that some inconclusive areas have received more attention than others. Our results should guide researchers towards conducting research on the topics most in need and, by doing so, strengthen the clinical practice guideline recommendations.

RESUMO

BACKGROUND: The optimal management of hypertrophic cardiomyopathy (HCM) patients with postoperative atrial fibrillation (POAF) after surgical myectomy remains unknown. We sought to investigate the association between POAF and atrial fibrillation (AF) or cardioembolic events during follow-up to bridge this gap. METHODS: Patients undergoing surgical myectomy at 2 HCM referral centres in North America from 2002 to 2020 were included in this study. Patients with preoperative AF were excluded. POAF was defined as any episode of AF within 30 days after surgery. RESULTS: Of 1176 patients, 375 (31.9%) had POAF. Age (adjusted hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.03-1.06; P < 0.001), premyectomy left atrial diameter (LAD; adjusted HR 1.6, 95% CI 1.32-2.02; P < 0.001), and smoking (adjusted HR 1.60, 95% CI 1.17-2.20; P = 0.001) were associated with POAF on multivariable analysis. Of 934 patients with follow-up data, of duration 4.3 ± 4.1 years, AF was detected in 86 (9.2%). Only POAF (HR 4.20, 95% CI 2.44-7.23; P < 0.001), previous history of stroke (HR 4.81, 95% CI 1.63-14.17; P = 0.01), and postmyectomy LAD (HR 1.80, 95% CI 1.21-2.70; P = 0.004) were associated with AF incidence during follow-up. Cardioembolic events occurred in only 15 patients (1.6%). POAF was not associated with increased cardioembolic risk, with only 3 patients with POAF suffering such an event, all more than 4 years after surgery. CONCLUSIONS: POAF is common in HCM patients undergoing myectomy and is a predictor of AF during follow-up. Over long-term follow-up, cardioembolic events are uncommon. These findings suggest that routine long-term anticoagulation for all HCM patients with postmyectomy AF is not justified after the initial postoperative period.

RESUMO

CONTEXT: The Cardiovascular and Renal Drugs Advisory Committee (CRDAC) of the Food and Drug Administration (FDA) reviews safety and efficacy data for cardiovascular and renal drugs, ultimately making recommendations to the Commissioner of Food and Drugs for approval. The Open Public Hearing segment of these meetings allows for patients, advocates, healthcare professionals, clinical trialists, and members of the public to provide testimony, which often results in expressing their preference for, or against, drug approval. Prior to providing testimony, the public speakers are highly encouraged to disclose any financial conflicts of interest (FCOIs) with the sponsor or other groups. Given the potential influence of these speakers on drug approval recommendations, we investigated the industry associations disclosed by public speakers in the Open Public Hearing section of the CRDAC meetings. Previous studies, such as one done by Lurie et al. indicated that positive testimony is tied to a higher likelihood of drug approval, and because drug companies provide financial compensation for speakers to provide testimony in general, we wanted to determine the likelihood with which speakers who have an FCOI provided a positive testimony vs. those without any FCOI. OBJECTIVES: The purpose is to evaluate whether public speakers with an FCOI are more likely to provide positive testimony regarding the drug in question during the CRDAC of the FDA between February 2009 and December 2019 through the use of publicly available transcripts. METHODS: Independent researchers investigated public transcripts and minutes of the CRDAC meetings with public speakers (n=20). We identified all speakers, along with characteristics such as an FCOI, and classified statements utilizing a pilot-tested Google form. The data collected were analyzed utilizing Stata. The speaker's testimony was then compared with their FCOI. An ordered logistic regression was performed utilizing the speaker's testimony regarding the drug as the dependent variable. RESULTS: Of the 88 speakers represented in our sample, 35 (35/88, 39.8%) disclosed an FCOI, most commonly regarding travel cost. Among speakers with an FCOI, 30 (30/35, 85.7%) spoke positively. Speakers with an FCOI were 4.96 times more likely to provide positive testimony (OR=4.96, 95% CI 1.67-14.78). Speakers with the disease were also more likely to provide positive testimony (OR=13.05, 95% CI 2.84-59.93). CONCLUSIONS: Public speakers often play a role during meetings, and they may also have an FCOI, most commonly related to travel expenses. Our study shows that speakers with an FCOI are more likely to provide positive testimony. Stipulations, such as requiring disclosure of FCOI and randomizing the selection process of speakers, can help ensure the integrity of the drug approval process.

RESUMO

OBJECTIVE: Evidence-based decision making is crucial in reducing the health and economic burdens imposed by tonsillar-related pathologies. Clinical practice guidelines are used to guide these decisions; however, uptake of recommendations in these guidelines is low. Systematic reviews are the highest level of evidence used to influence guideline recommendations; therefore, improving the reporting and methodological quality of systematic reviews related to tonsillar-related pathologies may improve guideline uptake and patient care. METHODS: We used PubMed to search for all clinical practice guidelines related to tonsillar-related pathologies from 2010 to 2020. Included guidelines were then searched for all systematic reviews and meta-analyses. Study characteristics were extracted from each cited systematic review/meta-analysis before being evaluated using the PRISMA (Preferred Reporting Instrument for Systematic Reviews and Meta-Analyses) and AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews 2) instruments. We then compared systematic reviews conducted by a Cochrane systematic review group with non-Cochrane systematic reviews. RESULTS: Seven clinical practice guidelines were included in our study and within these guidelines 98 SRs/MAs were cited, 80 of which were unique and included. Systematic reviews composed 9.1% (98/1082) of all guideline citations. Guideline PRISMA scores ranged from 0.47 to 0.83 with a mean score of 0.71 (n = 80) and guideline AMSTAR-2 scores ranged from 0.52 to 0.83 with a mean of 0.56 (7.29/13) and 0.75 (11.94/16) (n = 80). Cochrane systematic reviews displayed greater PRISMA (0.88 vs. 0.64: p < 0.001) and AMSTAR-2 (0.90 vs. 0.57; p < 0.001) scores compared to the non-Cochrane studies. We found PRISMA and AMSTAR-2 scores were positively correlated across guidelines (r = 0.93). CONCLUSION: Wide variation exists in adherence to PRISMA and AMSTAR-2 guidelines among systematic reviews cited in clinical practice guidelines for tonsillar-related pathologies. Prior registration and adequate risk of bias assessment are two areas where improvements may be needed. Given the importance of guideline uptake, careful considerations to improve the methodological and reporting quality of evidence supporting tonsillar-related pathology recommendations are necessary.

RESUMO

Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM) and is an important cause of morbidity and embolic stroke. The impact of outflow obstruction and the influence of surgical septal myectomy on the development of new-onset AF has not been well described. Consecutive patients with HCM without previous AF were followed for 5.0 ± 3.6 years for new-onset AF, including 717 with obstruction who did not undergo surgical myectomy (outflow gradients ≥30 mm Hg at rest or after provocation), 555 with nonobstructive HCM (outflow gradients <30 mm Hg), and 503 who underwent surgical myectomy. Patients with obstructive HCM who did not undergo myectomy had a 1.5-fold increased risk for new-onset AF compared with nonobstructive HCM (26% vs 16% at 10 years, hazard ratio = 0.69, p = 0.02). Patients who underwent myectomy had more advanced heart failure (95% vs 18% New York Heart Association class III, p <0.001) and had larger left atrium dimension (42 ± 7 vs 41 ± 7 mm; p <0.01) as compared with patients with obstructive HCM who did not undergo myectomy. However, after myectomy, the risk of new-onset AF was significantly lower than nonoperated obstructive (17% vs 26% at 10 years, p = 0.04) and no different from the risk of AF in patients with nonobstructive HC (hazard ratio 0.95, p = 0.81). In conclusion, patients with HCM with outflow obstruction are at a higher risk for AF compared with patients with nonobstructive HCM. However, after surgical myectomy, the risk for new-onset AF is substantially reduced. In addition to the known benefits of myectomy to permanently relieve outflow tract obstruction and mitral regurgitation, reverse heart failure symptoms, and increase longevity, myectomy is now shown to decrease susceptibility to AF in HCM.

RESUMO

BACKGROUND: Accurate assessment of right atrial pressure (RAP) and pulmonary artery systolic pressure (PASP) is critical in the management of heart transplant recipients. The accuracy of echocardiography in estimating these pressures has been debated. OBJECTIVE: To assess the correlation and agreement between echocardiographic estimations of right heart pressures with those of respective invasive hemodynamic measurements by right heart catheterization (RHC) in adult heart transplant recipients. METHODS: This is a prospective evaluation of 84 unique measurements from heart transplant recipients who underwent RHC followed by standard echocardiographic evaluation within 159 ± 64 min with no intervening medication changes. The relationship between noninvasive pressure estimations and invasive hemodynamic measurements was examined. RESULTS: Mean RAP was 7 ± 5 mmHg and mean PASP was 33 ± 8 mmHg by RHC. There was no significant correlation between echocardiographic estimation of RAP and invasive RAP (Spearman's rho = -0.05, p = .7), and no significant agreement between these two variables (weighted kappa = -0.1). There was a modest correlation between echocardiographic estimation of PASP and invasive PASP (r = .39, p = .002). Bland-Altman analysis showed a mean bias of 2.1 ± 9 mmHg (limits of agreement = -15 to 20 mmHg). CONCLUSION: In heart transplant recipients, there is no significant correlation or agreement between echocardiographic RAP estimation and invasively determined RAP. Noninvasive PASP estimation correlates significantly but modestly with invasively measured PASP. Further refinement of echocardiographic methods for assessment of RAP is warranted in this unique patient population.

RESUMO

Background: Thus, the purpose of the present study was to (1) characterize common postoperative complications and (2) quantify the rates of revision in patients undergoing hemiarthroplasty to reverse total shoulder arthroplasty revisional surgery. We hypothesize that hardware loosenings will be the most common complication to occur in the sample, with the humeral component being the most common loosening. Methods: This systematic review adhered to PRISMA reporting guideline. For our inclusion criteria, we included any study that contained intraoperative and/or postoperative complication data, and revision rates on patients who had undergone revision reverse total shoulder arthroplasty due to a failed hemiarthroplasty. Complications include neurologic injury, deep surgical site infections, hardware loosening/prosthetic instability, and postoperative fractures (acromion, glenoid, and humeral fractures). Results: The study contained 22 studies that assessed complications from shoulders that had revision reverse total shoulder arthroplasty from a hemiarthroplasty, with a total sample of 925 shoulders. We found that the most common complication to occur was hardware loosenings (5.3%), and of the hardware loosenings, humeral loosenings (3.8%) were the most common. The revision rate was found to be 10.7%. Conclusion: This systematic review found that revision reverse total shoulder arthroplasty for failed hemiarthroplasty has a high overall complication and reintervention rates, specifically for hardware loosening and revision rates.

RESUMO

OBJECTIVE: In light of the current national mental health crisis, we use Google Trends, Twitter and data obtained from the National Suicide Prevention Lifeline to evaluate the effect of '1-800-273-8255' on public awareness for the National Suicide Prevention Lifeline. DESIGN: Cross-sectional analysis. MAIN OUTCOME MEASURES: We extracted data from Google Trends and Twitter for terms related to suicide following the release of Logic's song, '1-800-273-8255'. We then used a forecasting autoregressive integrated moving algorithm model to determine the greater than expected search interest. RESULTS: Google searches for 'Suicide Hotline' increased 49% more than expected the day after Logic's song was released and sustained increase of queries resulted in an average relative search volume of 59.5%-9.1% higher than the mean forecasted value of 50.4% for the 28 days following the release. Tweets that engaged with the account '@800 273talk' on Twitter increased by 10 450% more than expected the day after the song was released and increased by a mean of 1497% greater than expected the week after the songs released. CONCLUSION: Findings from our study suggest that the entertainment industry can play an important role in increasing awareness of hotline numbers. Logic's song provides an example of a positive influence on public health and provides support for further development and standards for proper awareness of suicide in the public view.

RESUMO

INTRODUCTION: Complete reporting of systematic reviews of interventions is essential to the interpretation of research findings and the reproducibility of research results. The Template for Intervention Description and Replication (TIDieR) checklist-and the version specific to systematic reviews (TIDieR-SR)-was created to provide authors and researchers an evidence-based guide for reporting trial and systematic review interventions. In this study, we apply TIDieR-SR to Cochrane systematic reviews of surgical interventions. METHODS: We searched the Cochrane Database for relevant systematic reviews. Two investigators applied inclusion/exclusion criteria to all titles/abstracts and full texts. These same investigators extracted all data in duplicate while masked to the other's data. The primary outcome was adherence to TIDieR-SR items. RESULTS: Two hundred and thirty-eight systematic reviews were included. Overall, included SRs adhered to a median of 6 (IQR 5-7) out of eight TIDieR-SR items. The item with the lowest adherence was item 7 (share intervention materials, 1/238 (0.4%). DISCUSSION: Our results are encouraging, but the generalisability of our findings is compromised by the inclusion of only Cochrane systematic reviews. Future reporting of intervention materials is likely to improve the application of effective surgical interventions in the clinical practice.

RESUMO

BACKGROUND: Vasodilatory shock refractory to catecholamine vasopressors and arginine vasopressin is highly morbid and responsible for significant mortality. Synthetic angiotensin II is a potent vasoconstrictor that may be suitable for use in these patients. RESEARCH QUESTION: What is the safety and effectiveness of angiotensin II and what variables are associated with a favorable hemodynamic response? STUDY DESIGN AND METHODS: We performed a multicenter, retrospective study at five tertiary medical centers in the United States. The primary end point of hemodynamic responsiveness to angiotensin II was defined as attainment of mean arterial pressure (MAP) of ≥ 65 mm Hg with a stable or reduced total vasopressor dosage 3 h after drug initiation. RESULTS: Of 270 included patients, 181 (67%) demonstrated hemodynamic responsiveness to angiotensin II. Responders showed a greater increase in MAP (+10.3 mm Hg vs +1.6 mm Hg, P < .001) and reduction in vasopressor dosage (-0.20 µg/kg/min vs +0.04 µg/kg/min; P < .001) compared with nonresponders at 3 h. Variables associated with favorable hemodynamic response included lower lactate concentration (OR 1.11; 95% CI, 1.05-1.17, P < .001) and receipt of vasopressin (OR, 6.05; 95% CI, 1.98-18.6; P = .002). In severity-adjusted multivariate analysis, hemodynamic responsiveness to angiotensin II was associated with reduced likelihood of 30-day mortality (hazard ratio, 0.50; 95% CI, 0.35-0.71; P < .001). Arrhythmias occurred in 28 patients (10%) and VTE was identified in 4 patients. INTERPRETATION: In postmarketing use for vasopressor-refractory shock, 67% of angiotensin II recipients demonstrated a favorable hemodynamic response. Patients with lower lactate concentrations and those receiving vasopressin were more likely to respond to angiotensin II. Patients who responded to angiotensin II experienced reduced mortality.

RESUMO

OBJECTIVES/HYPOTHESIS: Spin-the practice of adding or omitting information intentionally or unintentionally to make the results of a study more favorable-may influence clinical decision making, especially when present in study abstracts. Here, we quantify and characterize the presence of spin in the abstracts of systematic reviews regarding tonsillectomy. METHODS: This study is an analysis of systematic review abstracts. Searches were conducted on September 23, 2019 on PubMed and Embase using the advanced search feature to retrieve systematic reviews regarding tonsillectomies. The nine most severe forms of spin were then evaluated. Spin was classified by two investigators in parallel, with each blinded to the classifications of the other. Study characteristics were also recorded in duplicate. Consensus meetings between investigators were held to resolve disagreements. RESULTS: In the 85 included systematic reviews, at least one form of spin was present in 44.7% (38/85) of abstracts. Journals with higher impact factors were less likely to contain spin in the abstracts of systematic reviews (point biserial correlation coefficient of -0.30). No statistically significant associations were found between the presence of spin and intervention type (P = .56) or adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (P = .08); however, there was a significant association between spin and funding source (P = .03). CONCLUSIONS: Spin was common in the abstracts of our sample of tonsillectomy systematic reviews. Researchers, clinicians, and peer reviewers could benefit from learning to recognize spin in medical literature. Further research is needed into the effects of spin on clinical decision making. LEVEL OF EVIDENCE: NA Laryngoscope, 2020.

RESUMO

Dubin-Johnson syndrome is a rare, benign disorder that results in conjugated hyperbilirubinemia. The disease manifests as intermittent jaundice without long-term hepatic or other clinical complications. This article reports a case of Dubin-Johnson syndrome, which was identified during cardiac transplant evaluation for cardiomyopathy secondary to a polyglycogen storage disease. The patient successfully underwent an orthotopic heart transplant. Postoperatively, her conjugated hyperbilirubinemia increased as compared to her baseline but resolved after several weeks. This report briefly reviews the hepatic manifestations in patients with Dubin-Johnson syndrome undergoing major surgery and highlights urinary coproporphyrin as a useful diagnostic test for Dubin-Johnson syndrome.
