Parent-Reported Suicidal Ideation in Three Population-Based Samples of School-Aged Korean Children With Autism Spectrum Disorder and Autism Spectrum Screening Questionnaire Screen Positivity.

OBJECTIVES: Higher prevalence of suicidality has been reported in individuals with ASD. This study aimed to (1) Estimate the prevalence of suicidal ideation (SI) in epidemiologically-ascertained, population-based, samples of children with ASD or Autism Spectrum Screening Questionnaire (ASSQ) Screen Positivity (ASP); (2) Determine whether ASD/ASP is an independent risk factor for SI, controlling for known SI risk factors; and, (3) Develop an explanatory model for SI in children with ASD/ASP. METHODS: Participants came from three epidemiologically-ascertained samples of school-aged Korean children (n = 14,423; 3,702; 4,837). ASSQ ≥ 14 was the cutoff for ASP. A subsample (n = 86) was confirmed to have ASD. SI was based on parents' endorsement of items on the Behavioral Assessment System for Children-2-Parent Report Scale-Children. Logistic regressions were used to assess associations between SI and ASD/ASP, controlling for demographics, peer victimization, behavior problems, and depression. To develop an explanatory model for SI within ASD/ASP, the associations between SI and child characteristics (comorbid conditions, ASD symptoms, IQ, adaptive function) were tested. RESULTS: SI was higher in children with ASD (14%) and ASP (16.6-27.4%) than ASSQ Screen Negative (ASN) peers (3.4-6.9%). ASD/ASP was strongly predictive of SI (ORs: 2.87-5.67), after controlling for known SI risk factors compared to ASN. Within the ASD and ASP groups, anxiety was the strongest predictor of SI. CONCLUSIONS: SI prevalence was higher in non-clinical samples of children with ASD and ASP, relative to ASN peers. These results underscore the need for routine screening for SI in children with ASD and social difficulties, particularly those with high anxiety. HighlightsPopulation-based, epidemiologically-ascertained, school-aged childrenASD and ASP are independent risk factors for SI in school-aged childrenAnxiety is an independent risk factor for SI in children with ASD or ASP.

Prenatal exposure to paternal smoking and likelihood for autism spectrum disorder.

LAY ABSTRACT: What is Already Known about This Subject: Genetics, (including de novo mutations), environmental factors (including toxic exposures), and their interactions impact autism spectrum disorder etiology. Paternal smoking is a candidate risk for autism spectrum disorder due to biological plausibility, high prevalence, and potential intervention.What This Study Adds: This original study and its replication confirms that paternal factors can substantially contribute to autism spectrum disorder risk for their offspring. It specifically indicates that paternal smoking both before and during pregnancy contributes significantly to autism spectrum disorder risk.Implications for practice, research, or policy: Smoking prevention, especially in pregnancy planning, may decrease autism spectrum disorder risk in offspring.

Construção e Avaliação para 15 Listas de Palavras Baseadas no Paradigma Deese-Roediger-McDermott / Construction and Evaluation for 15-Word Lists Based on the Deese-Roediger-McDermott Paradigm

Resumo Com base nos estudos conduzidos de acordo com o paradigma Deese-Roediger-McDermott (DRM), em quais palavras de uma lista tendem a evocar outros itens relacionados, utilizado em pesquisas de falsas memórias, neste estudo elaborou-se 15 listas de palavras semanticamente relacionadas para o português. Para a elaboração das listas, foram considerados critérios como frequência de palavras no corpus de português brasileiro e extensão de palavras. A pré-seleção guiada por características linguísticas visava controlar possíveis vieses por parte dos voluntários. Testes de associação semântica e concretude de palavras foram realizados para apurar a conveniência dos itens selecionados, e um teste de recordação livre foi conduzido para avaliar características de evocação. Sugerimos a utilização das listas de palavras em pesquisas que avaliem falsas memórias.

Abstract Based on studies conducted in accordance with the Deese-Roediger-McDermott (DRM) paradigm, in which words of a list tend to evoke other related items, used in false memory research, this study produced 15 lists of semantically related words for Brazilian Portuguese. For the preparation of the lists, certain criteria were considered, such as word length and frequency of words in a Brazilian Portuguese corpus. Pre-selection guided by linguistic characteristics aimed to control possible biases among volunteers. Semantic association and concreteness tests were carried out to determine the suitability of the selected items, and a free recall test was performed to evaluate evocation characteristics. We suggest using word lists in researches that evaluate false memories.

Effects of a 2-year behavioral weight loss intervention on sleep and mood in obese individuals treated in primary care practice.

OBJECTIVE: To examine the effect of weight loss on sleep duration, sleep quality, and mood in 390 obese men and women who received one of three behavioral weight loss interventions in the Practice-based Opportunities for Weight Reduction trial at the University of Pennsylvania (POWER-UP). METHODS: Sleep duration and quality were assessed at baseline and months 6 and 24 by the Pittsburgh Sleep Quality Index (PSQI) questionnaire and mood by the Patient Health Questionnaire-8 (PHQ-8). Changes in sleep and mood were examined according to treatment group and based on participants' having lost ≥5% of initial weight vs. <5%. RESULTS: There were few significant differences between treatment groups in changes in sleep or mood. At month 6, however, mean (±SD) min of sleep increased significantly more in participants who lost ≥5% vs. <5% (21.6 ± 7.2 vs. 1.2 ± 6.0 min, P = 0.0031). PSQI total scores similarly improved (declined) more in those who lost ≥5% vs. <5% (-1.2 ± 0.2 vs. -0.4 ± 0.2, P < 0.001), as did PHQ-8 scores (-2.5 ± 0.4 vs. -0.1 ± 0.3, P < 0.0001). At month 24, only the differences in mood remained statistically significant (P < 0.05). CONCLUSION: Losing ≥5% of initial weight was associated with short-term improvements in sleep duration and sleep quality, as well as favorable short- and long-term changes in mood.

Behavioral treatment of obesity in patients encountered in primary care settings: a systematic review.

IMPORTANCE: In 2011, the Centers for Medicare & Medicaid Services (CMS) approved intensive behavioral weight loss counseling for approximately 14 face-to-face, 10- to 15-minute sessions over 6 months for obese beneficiaries in primary care settings, when delivered by physicians and other CMS-defined primary care practitioners. OBJECTIVE: To conduct a systematic review of behavioral counseling for overweight and obese patients recruited from primary care, as delivered by primary care practitioners working alone or with trained interventionists (eg, medical assistants, registered dietitians), or by trained interventionists working independently. EVIDENCE REVIEW: We searched PubMed, CINAHL, and EMBASE for randomized controlled trials published between January 1980 and June 2014 that recruited overweight and obese patients from primary care; provided behavioral counseling (ie, diet, exercise, and behavioral therapy) for at least 3 months, with at least 6 months of postrandomization follow-up; included at least 15 participants per treatment group and objectively measured weights; and had a comparator, an intention-to-treat analysis, and attrition of less than 30% at 1 year or less than 40% at longer follow-up. FINDINGS: Review of 3304 abstracts yielded 12 trials, involving 3893 participants, that met inclusion-exclusion criteria and prespecified quality ratings. No studies were found in which primary care practitioners delivered counseling that followed the CMS guidelines. Mean 6-month weight changes from baseline in the intervention groups ranged from a loss of 0.3 kg to 6.6 kg. In the control group, mean change ranged from a gain of 0.9 kg to a loss of 2.0 kg. Weight loss in both groups generally declined with longer follow-up (12-24 months). Interventions that prescribed both reduced energy intake (eg, ≥ 500 kcal/d) and increased physical activity (eg, ≥150 minutes a week of walking), with traditional behavioral therapy, generally produced larger weight loss than interventions without all 3 specific components. In the former trials, more treatment sessions, delivered in person or by telephone by trained interventionists, were associated with greater mean weight loss and likelihood of patients losing 5% or more of baseline weight. CONCLUSIONS AND RELEVANCE: Intensive behavioral counseling can induce clinically meaningful weight loss, but there is little research on primary care practitioners providing such care. The present findings suggest that a range of trained interventionists, who deliver counseling in person or by telephone, could be considered for treating overweight or obesity in patients encountered in primary care settings.

Robotic totally endoscopic coronary artery bypass grafting in men and women: are there sex differences in outcome?

BACKGROUND: According to several studies, women are at higher risk for mortality and experience less relief of angina after coronary artery bypass graft surgery (CABG) than men. Sex-related differences in patients undergoing totally endoscopic coronary bypass grafting (TECABG) have not been investigated thus far. The aim of the present study was to evaluate the impact of sex on the outcome of patients undergoing TECABG. METHODS: The data of 500 consecutive patients (364 male, 136 female) undergoing TECABG using the da Vinci telemanipulation system (Intuitive Surgical, Sunnyvale, CA) from 2001 to 2011 at two institutions were investigated regarding sex-related differences in short-term and long-term outcome. RESULTS: In all, 334 single, 150 double, 15 triple, and 1 quadruple TECABG procedures were carried out. Female patients were significantly older (63 years [range, 26 to 90] versus 59 years [range, 31 to 85], p = 0.001) and had higher European System for Cardiac Operative Risk Evaluation score levels (3 [range, 0 to 11] versus 2 [range, 0 to 13], p < 0.001). Male patients received slightly more grafts (1 [range, 1 to 4] versus 1 [range, 1 to 3], p = 0.028), female patients were more likely to undergo beating heart surgery (20% versus 28%, p = 0.042). In-hospital mortality was 3 of 364 men (0.8%) and 2 of 136 women (1.5%; p = 0.513). Comparison of long-term-survival revealed 1-, 3- and 5-year survival rates of 96%, 96%, and 95% in men and 96%, 96%, and 96% in women, respectively, without any significant difference. Analysis of freedom from major adverse cardiac and cerebrovascular events revealed 1-, 3-, and 5-year rates of 86%, 84%, and 82% in men and 85%, 81%, and 81% in women, respectively, without any significant difference. CONCLUSIONS: Our data show that women undergoing TECABG have outcomes similar to those of men.

Factors influencing hospital length of stay after robotic totally endoscopic coronary artery bypass grafting.

BACKGROUND: Robotic totally endoscopic coronary artery bypass grafting (TECAB) is an evolving minimally invasive technology with the potential to reduce hospital length of stay (LOS). Little is known about the factors that influence LOS after this procedure. The aim of this study is to define the preoperative, intraoperative, and postoperative variables that predict LOS after TECAB. METHODS: From 2001 to 2011, 541 patients, aged 60 years (range, 26 to 90 years), 394 (72.8%) male, 147 (27.1%) female, underwent TECAB using the daVinci telemanipulation system at one European and one American institution. Three hundred forty-six (63.9%) single-, 171 (31.6%) double-, 23 (4.2%) triple-, and 1 (0.2%) quadruple-vessel TECABs were carried out with an overall LOS of 6 days (range, 2 to 54 days) and 30-day mortality of 0.9% (5 of 541); 44.5% of patients (241 of 541) were hybrid intent-to-treat candidates. RESULTS: The following variables showed significant positive correlation with LOS: age, r = 0.188 (p < 0.001); Society of Thoracic Surgeons risk score, r = 0.263 (p < 0.001); EuroSCORE, r = 0.191 (p < 0.001); creatinine, r = 0.135 (p = 0.002); and operative time, r = 0.216 (p < 0.001). Other factors that had significant influence on LOS were hemodialysis (p = 0.037), cerebrovascular disease (p = 0.002), learning curve case (p < 0.001), intraoperative surgical problem (p < 0.001), conversion or on-table revision (p < 0.001), revision for bleeding (p < 0.001), postoperative stroke (p < 0.001), intraaortic balloon pump (p < 0.001), hemodialysis (p < 0.001), and atrial fibrillation (p < 0.001). By multivariate analysis, learning curve case, conversion or on-table revision, and revision for bleeding were independent predictors for prolonged LOS (defined as LOS > 6 days). CONCLUSIONS: Multiple variables affect LOS after TECAB. Older patients, patients on hemodialysis, patients with cerebrovascular disease, and those with higher general risk scores should expect prolonged LOS. Intraoperative surgical difficulties and conversion to open coronary artery bypass grafting also lead to extended LOS. Postoperative events that are known to prolong LOS in open coronary artery bypass grafting also prolong LOS after TECAB.

Five hundred cases of robotic totally endoscopic coronary artery bypass grafting: predictors of success and safety.

BACKGROUND: Robotic technology has enabled totally endoscopic coronary artery bypass (TECAB) grafting. Little information is available on factors associated with successful and safe performance of TECAB. We report a 10-year multicenter experience with 500 cases, elucidating on predictors of success and safety in TECAB procedures. METHODS: Between 2001 and 2011, 500 patients (364 [73%] men; 136 [27%] women; median age [minimum-maximum] 60 years [31-90 years], median EuroSCORE 2 [0-13]), underwent TECAB. Single, double, triple, and quadruple TECAB was performed in 334, 150, 15, and 1 patient, respectively. Univariate analysis and binary regression models were used to identify predictors of success and safety. Success was defined as freedom from any adverse event and conversion procedure, safety was defined as freedom from major adverse cardiac and cerebral events, major vascular injury, and long-term ventilation. RESULTS: Success and safety rates were 80% (400 cases) and 95% (474 cases), respectively. Intraoperative conversions to larger thoracic incisions were required in 49 (10%) patients. The median operative time was 305 minutes (112-1,050 minutes), and the mean lengths of stay in the intensive unit (ICU) and in hospital were 23 hours (11-1,048 hours) and 6 days (2-4 days), respectively. Independent predictors of success were single-vessel TECAB (p = 0.004), arrested-heart (AH)-TECAB (p = 0.027), non-learning curve case (p = 0.049), and transthoracic assistance (p = 0.035). The only independent predictor of safety was EuroSCORE (p = 0.002). CONCLUSIONS: Single-vessel and multivessel TECAB procedures can be safely performed with good reproducible results. Predictors of success include procedure simplicity and non-learning curve cases, whereas predictors of safety are mainly associated with patient selection.
