RESUMO

Approved therapies for the treatment of patients with pulmonary arterial hypertension (PAH) mediate pulmonary vascular vasodilatation by targeting distinct biological pathways. International guidelines recommend that patients with an inadequate response to dual therapy with a phosphodiesterase type-5 inhibitor (PDE5i) and endothelin receptor antagonist (ERA), are recommended to either intensify oral therapy by adding a selective prostacyclin receptor (IP) agonist (selexipag), or switching from PDE5i to a soluble guanylate-cyclase stimulator (sGCS; riociguat). The clinical equipoise between these therapeutic choices provides the opportunity for evaluation of individualized therapeutic effects. Traditionally, invasive/hospital-based investigations are required to comprehensively assess disease severity and demonstrate treatment benefits. Regulatory-approved, minimally invasive monitors enable equivalent measurements to be obtained while patients are at home. In this 2 × 2 randomized crossover trial, patients with PAH established on guideline-recommended dual therapy and implanted with CardioMEMS™ (a wireless pulmonary artery sensor) and ConfirmRx™ (an insertable cardiac rhythm monitor), will receive ERA + sGCS, or PDEi + ERA + IP agonist. The study will evaluate clinical efficacy via established clinical investigations and remote monitoring technologies, with remote data relayed through regulatory-approved online clinical portals. The primary aim will be the change in right ventricular systolic volume measured by magnetic resonance imaging (MRI) from baseline to maximal tolerated dose with each therapy. Using data from MRI and other outcomes, including hemodynamics, physical activity, physiological measurements, quality of life, and side effect reporting, we will determine whether remote technology facilitates early evaluation of clinical efficacy, and investigate intra-patient efficacy of the two treatment approaches.

RESUMO

The Antarctic Circumpolar Current (ACC) represents the world's largest ocean-current system and affects global ocean circulation, climate and Antarctic ice-sheet stability1-3. Today, ACC dynamics are controlled by atmospheric forcing, oceanic density gradients and eddy activity4. Whereas palaeoceanographic reconstructions exhibit regional heterogeneity in ACC position and strength over Pleistocene glacial-interglacial cycles5-8, the long-term evolution of the ACC is poorly known. Here we document changes in ACC strength from sediment cores in the Pacific Southern Ocean. We find no linear long-term trend in ACC flow since 5.3 million years ago (Ma), in contrast to global cooling9 and increasing global ice volume10. Instead, we observe a reversal on a million-year timescale, from increasing ACC strength during Pliocene global cooling to a subsequent decrease with further Early Pleistocene cooling. This shift in the ACC regime coincided with a Southern Ocean reconfiguration that altered the sensitivity of the ACC to atmospheric and oceanic forcings11-13. We find ACC strength changes to be closely linked to 400,000-year eccentricity cycles, probably originating from modulation of precessional changes in the South Pacific jet stream linked to tropical Pacific temperature variability14. A persistent link between weaker ACC flow, equatorward-shifted opal deposition and reduced atmospheric CO2 during glacial periods first emerged during the Mid-Pleistocene Transition (MPT). The strongest ACC flow occurred during warmer-than-present intervals of the Plio-Pleistocene, providing evidence of potentially increasing ACC flow with future climate warming.

RESUMO

Importance: Children with speech and language difficulties are at risk for learning and behavioral problems. Objective: To review the evidence on screening for speech and language delay or disorders in children 5 years or younger to inform the US Preventive Services Task Force. Data Sources: PubMed/MEDLINE, Cochrane Library, PsycInfo, ERIC, Linguistic and Language Behavior Abstracts (ProQuest), and trial registries through January 17, 2023; surveillance through November 24, 2023. Study Selection: English-language studies of screening test accuracy, trials or cohort studies comparing screening vs no screening; randomized clinical trials (RCTs) of interventions. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, study quality, and data extraction; results were narratively summarized. Main Outcomes and Measures: Screening test accuracy, speech and language outcomes, school performance, function, quality of life, and harms. Results: Thirty-eight studies in 41 articles were included (N = 9006). No study evaluated the direct benefits of screening vs no screening. Twenty-one studies (n = 7489) assessed the accuracy of 23 different screening tools that varied with regard to whether they were designed to be completed by parents vs trained examiners, and to screen for global (any) language problems vs specific skills (eg, expressive language). Three studies assessing parent-reported tools for expressive language skills found consistently high sensitivity (range, 88%-93%) and specificity (range, 88%-85%). The accuracy of other screening tools varied widely. Seventeen RCTs (n = 1517) evaluated interventions for speech and language delay or disorders, although none enrolled children identified by routine screening in primary care. Two RCTs evaluating relatively intensive parental group training interventions (11 sessions) found benefit for different measures of expressive language skills, and 1 evaluating a less intensive intervention (6 sessions) found no difference between groups for any outcome. Two RCTs (n = 76) evaluating the Lidcombe Program of Early Stuttering Intervention delivered by speech-language pathologists featuring parent training found a 2.3% to 3.0% lower proportion of syllables stuttered at 9 months compared with the control group when delivered in clinic and via telehealth, respectively. Evidence on other interventions was limited. No RCTs reported on the harms of interventions. Conclusions and Relevance: No studies directly assessed the benefits and harms of screening. Some parent-reported screening tools for expressive language skills had reasonable accuracy for detecting expressive language delay. Group parent training programs for speech delay that provided at least 11 parental training sessions improved expressive language skills, and a stuttering intervention delivered by speech-language pathologists reduced stuttering frequency.

RESUMO

OBJECTIVE: Although there is a growing body of literature that discusses the etiology and impact of racial trauma, there are few evidence-based treatment modalities to support BIPOC individuals who have experienced race trauma. Furthermore, current clinicians are ill-equipped to navigate racial trauma symptoms in the therapy due to a dearth in training opportunities during their educational and professional careers. The current study addresses the dearth in racial trauma therapy training opportunities for clinicians through the implementation and evaluation of a training protocol based on the KNIFFLEY Racial Trauma Therapy Model (KRTTM) with community-based clinicians. METHOD: Fifty-four clinicians who participated in the KRTTM training protocol completed a 7-item efficacy scale as well as a 17-item training satisfaction survey before and at the end of the training. RESULTS: Results of the paired-samples t-test revealed a statistically significant change in perceived efficacy among clinicians who completed the KRTTM training. Specifically, survey scores among clinicians averaged approximately 22 (i.e., M = 22.2, SD = 4.9) at pretest and 30 (i.e., M = 29.8, SD = 3.7) at posttest, indicating a statistically significant increase in perceived efficacy, t(53), -9.9, p = .000. Further, results of the paired-samples t-test split by race indicated differences in pretest efficacy scores between White (M = 21.7, SD = 4.5) and BIPOC (M = 23.6, SD = 5.9) clinicians in this study. CONCLUSIONS: Overall, the results from the current study highlight that there is a need for more training on evidenced-based treatment models, to include the KRTTM intervention, to build clinicians' capacity to provide support to BIPOC individuals who have experienced racial trauma during their lifetimes.

RESUMO

In patients with heart failure, guideline directed medical therapy improves outcomes and requires close patient monitoring. Pulmonary artery pressure monitors permit remote assessment of cardiopulmonary haemodynamics and facilitate early intervention that has been shown to decrease heart failure hospitalization. Pressure sensors implanted in the pulmonary vasculature are stabilized through passive or active interaction with the anatomy and communicate with an external reader to relay invasively measured pressure by radiofrequency. A body mass index > 35 kg/m2 and chest circumference > 165 cm prevent use due to poor communication. Pulmonary vasculature anatomy is variable between patients and the pulmonary artery size, angulation of vessels and depth of sensor location from the chest wall in heart failure patients who may be candidates for pressure sensors remains largely unexamined. The present study analyses the size, angulation, and depth of the pulmonary artery at the position of implantation of two pulmonary artery pressure sensors: the CardioMEMS sensor typically implanted in the left pulmonary artery and the Cordella sensor implanted in the right pulmonary artery. Thirty-four computed tomography pulmonary angiograms from patients with heart failure were analysed using the MIMICS software. Distance from the bifurcation of the pulmonary artery to the implant site was shorter for the right pulmonary artery (4.55 ± 0.64 cm vs. 7.4 ± 1.3 cm) and vessel diameter at the implant site was larger (17.15 ± 2.87 mm vs. 11.83 ± 2.30 mm). Link distance (length of the communication path between sensor and reader) was shorter for the left pulmonary artery (9.40 ± 1.43 mm vs. 12.54 ± 1.37 mm). Therefore, the detailed analysis of pulmonary arterial anatomy using computed tomography pulmonary angiograms may alter the choice of implant location to reduce the risk of sensor migration and improve readability by minimizing sensor-to-reader link distance.

RESUMO

Background: Admission to a neonatal intensive care unit (NICU) for prematurity or illness is necessary for approximately 20% of newborns in Australia, resulting in parent-infant separation. Web cameras in the NICU provide a virtual link for parents to remain remotely connected to their infant during admission. Web camera use is increasing; however, there is limited evidence on the impact of web cameras on parents, infants, and neonatal staff. Objective: There were two objectives: (1) to determine the attitudes of parents and staff toward web cameras in the NICU and (2) to compare parental depression, anxiety, and stress levels using validated scales before and after web camera implementation in the NICU. Methods: A pre- and postevaluation survey was administered before and after implementation of the NICVIEW camera system in a tertiary NICU in Sydney, Australia. The NICVIEW camera system provides secure real-time viewing of infants and can be accessed from any device with an internet connection. Surveys were administered to parents of inpatients and staff, and included open- and closed-ended questions and Likert scales. Survey questions aimed to determine parent and staff attitudes and use of web cameras before and after implementation. In addition, pre- and postimplementation parental levels of depression, anxiety, and stress, as measured by the 21-item version of the Depression Anxiety Stress Scale (DASS-21) and Parental Stressor Scale: Neonatal Intensive Care Unit, were recorded. Results: In total, 94 parents and 109 staff members completed the pre- and postimplementation surveys. Post implementation, 43 of 44 (98%) parents supported web cameras, and 40 of 42 (95%) parents stated that they used web cameras. The most common reasons for support from parents included web cameras making parents feel more at ease, facilitating parent-infant bonding, increasing parental confidence in staff, and allowing others to see infants. There was no significant difference between the parental groups for the depression, anxiety, or stress scales measured by DASS-21. Staff support for web cameras increased significantly from 34 of 42 (81%) participants before to 64 of 67 (96%) participants after implementation (P=.01). Following implementation, there was a resolution in staff concerns about web cameras having an adverse impact on staff roles and privacy and security concerns. Conclusions: Web camera use in a tertiary Australian NICU was strongly supported by parents and staff and may reduce parental stress, facilitate parent-infant bonding, and encourage positive parent-staff engagement. Web cameras are a feasible method of providing continuity of care for families and should be considered as a standard of care in similarly resourced settings.

RESUMO

Importance: Neural tube defects are among the most common birth defects in the US. Objective: To review new evidence on the benefits and harms of folic acid supplementation for the prevention of neural tube defects to inform the US Preventive Services Task Force. Evidence Review: Sources included PubMed, Cochrane Library, Embase, and trial registries from July 1, 2015, through July 2, 2021; references; and experts, with surveillance through February 10, 2023. Two investigators independently reviewed English-language randomized studies and nonrandomized cohort studies in very highly developed countries that focused on the use of folic acid supplementation for the prevention of neural tube defect-affected pregnancies; methodological quality was dually and independently assessed. Findings: Twelve observational studies (reported in 13 publications) were eligible for this limited update (N = 1 244 072). Of these, 3 studies (n = 990 372) reported on the effect of folic acid supplementation on neural tube defects. For harms, 9 studies were eligible: 1 randomized clinical trial (n = 431) reported on variations in twin delivery, 7 observational studies (n = 761 125) reported on the incidence of autism spectrum disorder, and 1 observational study (n = 429 004) reported on maternal cancer. Two cohort studies and 1 case-control study newly identified in this update reported on the association between folic acid supplementation and neural tube defects (n = 990 372). One cohort study reported a statistically significant reduced risk of neural tube defects associated with folic acid supplementation taken before pregnancy (adjusted relative risk [aRR], 0.54 [95% CI, 0.31-0.91]), during pregnancy (aRR, 0.62 [95% CI, 0.39-0.97]), and before and during pregnancy (aRR, 0.49 [95% CI, 0.29-0.83]), but this association occurred for only the later of 2 periods studied (2006-2013 and not 1999-2005). No other statistically significant benefits were reported overall. No study reported statistically significant harms (multiple gestation, autism, and maternal cancer) associated with pregnancy-related folic acid exposure. Conclusions and Relevance: New evidence from observational studies provided additional evidence of the benefit of folic acid supplementation for preventing neural tube defects and no evidence of harms related to multiple gestation, autism, or maternal cancer. The new evidence was consistent with previously reviewed evidence on benefits and harms.

RESUMO

BACKGROUND: The development of atrial flutter and fibrillation (AFL/AF) in patients with pre-capillary pulmonary hypertension has been associated with an increased risk of morbidity and mortality. Rate and rhythm control strategies have not been directly compared. METHODS: Eighty-four patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH) with new-onset AFL/AF were identified in the ASPIRE registry. First, baseline characteristics and rates of sinus rhythm (SR) restoration of 3 arrhythmia management strategies (rate control, medical rhythm control and DC cardioversion, DCCV) in an early (2009-13) and later (2014-19) cohort were compared. Longer-term outcomes in patients who achieved SR versus those who did not were then explored. RESULTS: Sixty (71%) patients had AFL and 24 (29%) AF. Eighteen (22%) patients underwent rate control, 22 (26%) medical rhythm control and 44 (52%) DCCV. SR was restored in 33% treated by rate control, 59% medical rhythm control and 95% DCCV (p < 0.001). Restoration of SR was associated with greater improvement in functional class (FC) and Incremental Shuttle Walk Distance (p both <0.05). It also independently predicted superior survival (3-year survival 62% vs 23% in those remaining in AFL/AF, p < 0.0001). In addition, FC III/IV independently predicted higher mortality (HR 2.86, p = 0.007). Right atrial area independently predicted AFL/AF recurrence (OR 1.08, p = 0.01). DCCV was generally well tolerated with no immediate major complications. CONCLUSIONS: Restoration of SR is associated with superior functional improvement and survival in PAH/CTEPH compared with rate control. DCCV is generally safe and is more effective than medical therapy at achieving SR.

RESUMO

Importance: Obstructive sleep apnea (OSA) is associated with adverse health outcomes. Objective: To review the evidence on screening for OSA in asymptomatic adults or those with unrecognized OSA symptoms to inform the US Preventive Services Task Force. Data Sources: PubMed/MEDLINE, Cochrane Library, Embase, and trial registries through August 23, 2021; surveillance through September 23, 2022. Study Selection: English-language studies of screening test accuracy, randomized clinical trials (RCTs) of screening or treatment of OSA reporting health outcomes or harms, and systematic reviews of treatment reporting changes in blood pressure and apnea-hypopnea index (AHI) scores. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, and study quality. Meta-analysis of intervention trials. Main Outcomes and Measures: Test accuracy, excessive daytime sleepiness, sleep-related and general health-related quality of life (QOL), and harms. Results: Eighty-six studies were included (N = 11 051). No study directly compared screening with no screening. Screening accuracy of the Multivariable Apnea Prediction score followed by unattended home sleep testing for detecting severe OSA syndrome (AHI ≥30 and Epworth Sleepiness Scale [ESS] score >10) measured as the area under the curve in 2 studies (n = 702) was 0.80 (95% CI, 0.78 to 0.82) and 0.83 (95% CI, 0.77 to 0.90). Five studies assessing the accuracy of other screening tools were heterogeneous and results were inconsistent. Compared with inactive control, positive airway pressure was associated with a significant improvement in ESS score from baseline (pooled mean difference, -2.33 [95% CI, -2.75 to -1.90]; 47 trials; n = 7024), sleep-related QOL (standardized mean difference, 0.30 [95% CI, 0.19 to 0.42]; 17 trials; n = 3083), and general health-related QOL measured by the 36-Item Short Form Health Survey (SF-36) mental health component summary score change (pooled mean difference, 2.20 [95% CI, 0.95 to 3.44]; 15 trials; n = 2345) and SF-36 physical health component summary score change (pooled mean difference, 1.53 [95% CI, 0.29 to 2.77]; 13 trials; n = 2031). Use of mandibular advancement devices was also associated with a significantly larger ESS score change compared with controls (pooled mean difference, -1.67 [95% CI, 2.09 to -1.25]; 10 trials; n = 1540). Reporting of other health outcomes was sparse; no included trial found significant benefit associated with treatment on mortality, cardiovascular events, or motor vehicle crashes. In 3 systematic reviews, positive airway pressure was significantly associated with reduced blood pressure; however, the difference was relatively small (2-3 mm Hg). Conclusions and Relevance: The accuracy and clinical utility of OSA screening tools that could be used in primary care settings were uncertain. Positive airway pressure and mandibular advancement devices reduced ESS score. Trials of positive airway pressure found modest improvement in sleep-related and general health-related QOL but have not established whether treatment reduces mortality or improves most other health outcomes.

RESUMO

Importance: Depression, suicidal ideation, and self-harm behaviors in youth are associated with functional impairment and suicide. Objective: To review the evidence on screening for depression or suicide risk in children and adolescents to inform the US Preventive Services Task Force (USPSTF). Data Sources: PubMed, Cochrane Library, PsycINFO, CINAHL, and trial registries through July 19, 2021; references, experts, and surveillance through June 1, 2022. Study Selection: English-language, randomized clinical trials (RCTs) of screening for depression or suicide risk; diagnostic test accuracy studies; RCTs of psychotherapy and first-line pharmacotherapy; RCTs, observational studies, and systematic reviews reporting harms. Data Extraction and Synthesis: Two reviewers assessed titles/abstracts, full-text articles, and study quality and extracted data; when at least 3 similar studies were available, meta-analyses were conducted. Main Outcomes and Measures: Test accuracy, symptoms, response, remission, loss of diagnosis, mortality, functioning, suicide-related events, and adverse events. Results: Twenty-one studies (N = 5433) were included for depression and 19 studies (N = 6290) for suicide risk. For depression, no studies reported on the direct effects of screening on health outcomes, and 7 studies (n = 3281) reported sensitivity of screening instruments ranging from 0.59 to 0.94 and specificity from 0.38 to 0.96. Depression treatment with psychotherapy was associated with improved symptoms (Beck Depression Inventory pooled standardized mean difference, -0.58 [95% CI, -0.83 to -0.34]; n = 471; 4 studies; and Hamilton Depression Scale pooled mean difference, -2.25 [95% CI, -4.09 to -0.41]; n = 262; 3 studies) clinical response (3 studies with statistically significant results using varying thresholds), and loss of diagnosis (relative risk, 1.73 [95% CI, 1.00 to 3.00; n = 395; 4 studies). Pharmacotherapy was associated with improvement on symptoms (Children's Depression Rating Scale-Revised mean difference, -3.76 [95% CI, -5.95 to -1.57; n = 793; 3 studies), remission (relative risk, 1.20 [95% CI, 1.00 to 1.45]; n = 793; 3 studies) and functioning (Children's Global Assessment Scale pooled mean difference, 2.60 (95% CI, 0.78 to 4.42; n = 793; 3 studies). Other outcomes were not statistically significantly different. Differences in suicide-related outcomes and adverse events for pharmacotherapy when compared with placebo were not statistically significant. For suicide risk, no studies reported on the direct benefits of screening on health outcomes, and 2 RCTs (n = 2675) reported no harms of screening. One study (n = 581) reported on sensitivity of screening, ranging from 0.87 to 0.91; specificity was 0.60. Sixteen RCTs (n = 3034) reported on suicide risk interventions. Interventions were associated with lower scores for the Beck Hopelessness Scale (pooled mean difference, -2.35 [95% CI, -4.06 to -0.65]; n = 644; 4 RCTs). Findings for other suicide-related outcomes were mixed or not statistically significantly different. Conclusion and Relevance: Indirect evidence suggested that some screening instruments were reasonably accurate for detecting depression. Psychotherapy and pharmacotherapy were associated with some benefits and no statistically significant harms for depression, but the evidence was limited for suicide risk screening instruments and interventions.

RESUMO

Importance: Anxiety in children and adolescents is associated with impaired functioning, educational underachievement, and future mental health conditions. Objective: To review the evidence on screening for anxiety in children and adolescents to inform the US Preventive Services Task Force. Data Sources: PubMed, Cochrane Library, PsycINFO, CINAHL, and trial registries through July 19, 2021; references, experts, and surveillance through June 1, 2022. Study Selection: English-language, randomized clinical trials (RCTs) of screening; diagnostic test accuracy studies; RCTs of cognitive behavioral therapy (CBT) or US Food and Drug Administration-approved pharmacotherapy; RCTs, observational studies, and systematic reviews reporting harms. Data Extraction and Synthesis: Two reviewers assessed titles/abstracts, full-text articles, and study quality and extracted data; when at least 3 similar studies were available, meta-analyses were conducted. Main Outcomes and Measures: Test accuracy, symptoms, response, remission, loss of diagnosis, all-cause mortality, functioning, suicide-related symptoms or events, adverse events. Results: Thirty-nine studies (N = 6065) were included. No study reported on the direct benefits or harms of screening on health outcomes. Ten studies (n = 3260) reported the sensitivity of screening instruments, ranging from 0.34 to 1.00, with specificity ranging from 0.47 to 0.99. Twenty-nine RCTs (n = 2805) reported on treatment: 22 on CBT, 6 on pharmacotherapy, and 1 on CBT, sertraline, and CBT plus sertraline. CBT was associated with gains on several pooled measures of symptom improvement (magnitude of change varied by outcome measure), response (pooled relative risk [RR], 1.89 [95% CI, 1.17 to 3.05]; n = 606; 6 studies), remission (RR, 2.68 [95% CI, 1.48 to 4.88]; n = 321; 4 studies), and loss of diagnosis (RR range, 3.02-3.09) when compared with usual care or wait-list controls. The evidence on functioning for CBT was mixed. Pharmacotherapy, when compared with placebo, was associated with gains on 2 pooled measures of symptom improvement-mean difference (Pediatric Anxiety Rating Scale mean difference, -4.0 [95% CI, -5.5 to -2.5]; n = 726; 5 studies; and Clinical Global Impression-Severity scale mean difference, -0.84 [95% CI, -1.13 to -0.55]; n = 550; 4 studies) and response (RR, 2.11 [95% CI, 1.58 to 2.98]; n = 370; 5 studies)-but was mixed on measures of functioning. Eleven RCTs (n = 1293) reported harms of anxiety treatments. Suicide-related harms were rare, and the differences were not statistically significantly different. Conclusions and Relevance: Indirect evidence suggested that some screening instruments were reasonably accurate. CBT and pharmacotherapy were associated with benefits; no statistically significant association with harms was reported.

RESUMO

Importance: Of youths diagnosed with type 2 diabetes, many develop microvascular complications by young adulthood. Objective: To review the evidence on benefits and harms of screening children and adolescents for prediabetes and type 2 diabetes to inform the US Preventive Services Task Force (USPSTF). Data Sources: PubMed/MEDLINE, Cochrane Library, and trial registries through May 3, 2021; references; experts; literature surveillance through July 22, 2022. Study Selection: English-language controlled studies evaluating screening or interventions for prediabetes or type 2 diabetes that was screen detected or recently diagnosed. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, and study quality; qualitative synthesis of findings. Main Outcomes and Measures: Mortality, cardiovascular morbidity, diabetes-related morbidity, development of diabetes, quality of life, and harms. Results: This review included 8 publications (856 participants; mean age, 14 years [range, 10-17 years]). Of those, 6 were from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. No eligible studies directly evaluated the benefits or harms of screening. One randomized clinical trial (RCT) (TODAY; n = 699 adolescents with obesity; mean age, 14 years) comparing metformin, metformin plus rosiglitazone, and metformin plus lifestyle intervention reported that 2 youths with recently diagnosed diabetes developed kidney impairment (0 vs 1 vs 1, respectively; P > .99) and 11 developed diabetic ketoacidosis (5 vs 3 vs 3, respectively; P = .70). One RCT of 75 adolescents (mean age, 13 years) with obesity with prediabetes compared an intensive lifestyle intervention with standard care and reported that no participants in either group developed diabetes, although follow-up was only 6 months. Regarding harms of interventions, 2 RCTs assessing different comparisons enrolled youths with recently diagnosed diabetes. Major hypoglycemic events were reported by less than 1% of participants. Minor hypoglycemic events were more common among youths treated with metformin plus rosiglitazone than among those treated with metformin or metformin plus lifestyle intervention in TODAY (8.2% vs 4.3% vs 3.4%, P = .05). In 1 study, gastrointestinal adverse events were more commonly reported by those taking metformin than by those taking placebo (abdominal pain: 25% vs 12%; nausea/vomiting: 17% vs 10%; P not reported). Conclusions and Relevance: No eligible studies directly evaluated the benefits or harms of screening for prediabetes and type 2 diabetes in children and adolescents. For youths with prediabetes or recently diagnosed (not screen-detected) diabetes, the only eligible trials reported few health outcomes and found no difference between groups, although evidence was limited by substantial imprecision and a duration of follow-up likely insufficient to assess health outcomes.

RESUMO

AIMS: To investigate the outcomes and associated costs of haemodynamic-guided heart failure (HF) management with a pulmonary artery pressure (PAP) sensor in a multicentre European cohort. METHODS AND RESULTS: Data from all consecutive patients receiving a PAP sensor in Ziekenhuis Oost-Limburg, University Hospital Zurich and Sheffield Teaching Hospitals NHS Foundation Trust before January 2021 were collected. Medication changes, total number of HF hospitalizations and HF related health care costs (composed of HF hospitalizations, outpatient cardiology visits and monitoring costs) were compared between the pre-implantation and post-implantation period at 3, 6, and 12 months. PAP evolution post-implantation were grouped according to baseline mPAP ≥25 mmHg versus <25 mmHg and changes from baseline were analyzed via an area under the curve (AUC) analysis. A total of 48 patients received a PAP sensor (29 CardioMEMS and 19 Cordella devices) with a median follow-up of 19 (13-30) months. Mean age was 71 ± 10 years, 25.0% were female, 68.8% had a left ventricular ejection fraction < 50%, median NT-proBNP was 1801 (827-4503) pg/mL, and 89.6% were in NYHA class III. The number of diuretic therapy changes were non-significantly increased after 3 months (49 vs. 82; P = 0.284) and 6 months (82 vs. 127; P = 0.093) with a significant increase noted after 12 months (118 vs. 195; P = 0.005). The mPAP AUC decreased by -1418 mmHg-days for patients with a baseline mean PAP ≥ 25 mmHg. The number of HF hospitalizations was reduced for all patients after 6 (34 vs. 17; P = 0.014) and 12 months (48 vs. 29; P = 0.032). HF related health care costs were reduced from € 6286 to € 3761 at 6 months (P = 0.012) and from € 8960 to € 6167 at 12 months (P = 0.032). CONCLUSION: Haemodynamic-guided HF management reduces HF hospitalizations and HF related health care costs in selected HF patients amongst different European health care systems.

RESUMO

Background: Current European Society of Cardiology and European Respiratory Society guidelines recommend regular risk stratification with an aim of treating patients with pulmonary arterial hypertension (PAH) to improve or maintain low-risk status (<5% 1-year mortality). Methods: Consecutive patients with PAH who underwent cardiac magnetic resonance imaging (cMRI) were identified from the Assessing the Spectrum of Pulmonary hypertension Identified at a Referral centre (ASPIRE) registry. Kaplan-Meier survival curves, locally weighted scatterplot smoothing regression and multi-variable logistic regression analysis were performed. Results: In 311 consecutive, treatment-naïve patients with PAH undergoing cMRI including 121 undergoing follow-up cMRI, measures of right ventricular (RV) function including right ventricular ejection fraction (RVEF) and RV end systolic volume and right atrial (RA) area had prognostic value. However, only RV metrics were able to identify a low-risk status. Age (p < 0.01) and RVEF (p < 0.01) but not RA area were independent predictors of 1-year mortality. Conclusion: This study highlights the need for guidelines to include measures of RV function rather than RA area alone to aid the risk stratification of patients with PAH.

RESUMO

Importance: Eating disorders are associated with adverse health and social outcomes. Objective: To review the evidence on screening for eating disorders in adolescents and adults to inform the US Preventive Services Task Force. Data Sources: MEDLINE, Cochrane Library, PsycINFO, and trial registries through December 19, 2020; surveillance through January 1, 2022. Study Selection: English-language studies of screening test accuracy, randomized clinical trials (RCTs) of screening or interventions for eating disorders in populations with screen-detected or previously untreated eating disorders (trials limited to populations who are underweight were ineligible). Data Extraction and Synthesis: Dual review of abstracts, full-text articles, and study quality. Meta-analysis of test accuracy studies and intervention trials. Main Outcomes and Measures: Test accuracy, eating disorder symptom severity, quality of life, depression, and harms. Results: Fifty-seven studies were included (N = 10 773); 3 (n = 1073) limited to adolescents (mean or median age, 14-15 years). No study directly evaluated the benefits and harms of screening. Seventeen studies (n = 6804) evaluated screening test accuracy. The SCOFF questionnaire (cut point ≥2) had a pooled sensitivity of 84% (95% CI, 74% to 90%) and pooled specificity of 80% (95% CI, 65% to 89%) in adults (10 studies, n = 3684). Forty RCTs (n = 3969) evaluated interventions for eating disorders; none enrolled a screen-detected population. Lisdexamfetamine for binge eating disorder (4 RCTs; n = 900) was associated with larger reductions in eating disorder symptom severity on the Yale-Brown Obsessive Compulsive Scale modified for binge eating (YBOCS-BE) than placebo (pooled mean difference, -5.75 [95% CI, -8.32 to -3.17]). Two RCTs (n = 465) of topiramate for binge eating disorder found larger reductions in YBOCS-BE scores associated with topiramate than placebo, from -6.40 (95% CI, -8.16 to -4.64) to -2.55 (95% CI, -4.22 to -0.88). Nine pharmacotherapy trials (n = 2006) reported on harms. Compared with placebo, lisdexamfetamine was associated with higher rates of dry mouth, headache, and insomnia, and topiramate was associated with higher rates of paresthesia, taste perversion, confusion, and concentration difficulty. Twenty-four trials (n = 1644) assessed psychological interventions. Guided self-help for binge eating disorder improved eating disorder symptom severity more than control (pooled standardized mean difference, -0.96 [95% CI, -1.26 to -0.67]) (5 studies, n = 391). Evidence on other interventions was limited. Conclusions and Relevance: No studies directly assessed the benefits and harms of screening. The SCOFF questionnaire had adequate accuracy for detecting eating disorders among adults. No treatment trials enrolled screen-detected populations; guided self-help, lisdexamfetamine, and topiramate were effective for reducing eating disorder symptom severity among referred populations with binge eating disorder, but pharmacotherapies were also associated with harms.

RESUMO

Importance: Type 2 diabetes is common and is a leading cause of morbidity and disability. Objective: To review the evidence on screening for prediabetes and diabetes to inform the US Preventive Services Task Force (USPSTF). Data Sources: PubMed/MEDLINE, Cochrane Library, and trial registries through September 2019; references; and experts; literature surveillance through May 21, 2021. Study Selection: English-language controlled studies evaluating screening or interventions for prediabetes or diabetes that was screen detected or recently diagnosed. Data Extraction and Synthesis: Dual review of abstracts, full-text articles, and study quality; qualitative synthesis of findings; meta-analyses conducted when at least 3 similar studies were available. Main Outcomes and Measures: Mortality, cardiovascular morbidity, diabetes-related morbidity, development of diabetes, quality of life, and harms. Results: The review included 89 publications (N = 68 882). Two randomized clinical trials (RCTs) (25 120 participants) found no significant difference between screening and control groups for all-cause or cause-specific mortality at 10 years. For harms (eg, anxiety or worry), the trials reported no significant differences between screening and control groups. For recently diagnosed (not screen-detected) diabetes, 5 RCTs (5138 participants) were included. In the UK Prospective Diabetes Study, health outcomes were improved with intensive glucose control with sulfonylureas or insulin. For example, for all-cause mortality the relative risk (RR) was 0.87 (95% CI, 0.79 to 0.96) over 20 years (10-year posttrial assessment). For overweight persons, intensive glucose control with metformin improved health outcomes at the 10-year follow-up (eg, all-cause mortality: RR, 0.64 [95% CI, 0.45 to 0.91]), and benefits were maintained longer term. Lifestyle interventions (most involving >360 minutes) for obese or overweight persons with prediabetes were associated with reductions in the incidence of diabetes (23 RCTs; pooled RR, 0.78 [95% CI, 0.69 to 0.88]). Lifestyle interventions were also associated with improved intermediate outcomes, such as reduced weight, body mass index, systolic blood pressure, and diastolic blood pressure (pooled weighted mean difference, -1.7 mm Hg [95% CI, -2.6 to -0.8] and -1.2 mm Hg [95% CI, -2.0 to -0.4], respectively). Metformin was associated with a significant reduction in diabetes incidence (pooled RR, 0.73 [95% CI, 0.64 to 0.83]) and reduction in weight and body mass index. Conclusions and Relevance: Trials of screening for diabetes found no significant mortality benefit but had insufficient data to assess other health outcomes; evidence on harms of screening was limited. For persons with recently diagnosed (not screen-detected) diabetes, interventions improved health outcomes; for obese or overweight persons with prediabetes, interventions were associated with reduced incidence of diabetes and improvement in other intermediate outcomes.
