Attention Deficit Hyperactivity Disorder and Risk of Posttraumatic Stress and Related Disorders: A Prospective Longitudinal Evaluation in U.S. Army Soldiers

Crossâ sectional associations between attention deficit hyperactivity disorder (ADHD) and posttraumatic stress disorder (PTSD) have been observed, but longitudinal studies assessing this association are lacking. This prospective study evaluated the association between predeployment ADHD and postdeployment PTSD among U.S. Army soldiers. Soldiers who deployed to Afghanistan were surveyed before deployment (T0) and approximately 1 month (T1), 3 months (T2), and 9 months (T3) after their return. Logistic regression was performed to estimate the association between predeployment ADHD and postdeployment (T2 or T3) PTSD among 4,612 soldiers with data at all waves and no record of stimulant medication treatment during the study. To evaluate specificity of the ADHDâ PTSD association, we examined associations among predeployment ADHD, postdeployment major depressive episode (MDE), generalized anxiety disorder (GAD), and suicidal ideation. Weighted prevalence of ADHD predeployment was 6.1% (SE = 0.4%). Adjusting for other risk factors, predeployment ADHD was associated with risk of postdeployment PTSD, adjusted odds ratio (AOR) = 2.13, 95% CI [1.51, 3.00], p < .001, including incidence among soldiers with no predeployment history of PTSD, AOR = 2.50, 95% CI [1.69, 3.69], p < .001. ADHD was associated with postdeployment MDE, AOR = 2.80, 95% CI [2.01, 3.91], p < .001, and GAD, AOR = 3.04, 95% CI [2.10, 4.42], p < .001, but not suicidal ideation. Recognition of associations between predeployment ADHD and postdeployment PTSD, MDE, and GAD may inform targeted prevention efforts. Future research should examine whether treatment of ADHD is protective against PTSD and related disorders in traumaâ exposed individuals.ResumenSpanish Abstracts by Asociación Chilena de Estrés Traumático (ACET)El trastorno de déficit atencional con hiperactividad y el riesgo del trastorno de estrés postraumático y trastornos relacionados: Una evaluación longitudinal prospectiva en soldados del ejército estadounidenseTDAH Y RIESGO DE TEPT EN SOLDADOS DEL EJà RCITO DE EE.UU.Se han observado asociaciones transversales entre el trastorno por déficit de atención con hiperactividad (TDAH) y el trastorno por estrés postraumático (TEPT), pero faltan estudios longitudinales que evalúen esta asociación. Este estudio prospectivo evaluó la asociación entre el TDAH previo al despliegue y el TEPT posterior al despliegue entre los soldados del Ejército de Estados Unidos. Los soldados desplegados en Afganistán fueron encuestados antes del despliegue (T0) y aproximadamente 1 mes (T1), 3 meses (T2), y 9 meses (T3) después de su regreso del despliegue. Se realizó una regresión logística para estimar la asociación entre el TDAH previo al despliegue y el TEPT posterior al despliegue (T2 o T3) en 4.612 soldados con datos en todas las etapas y sin registro de tratamiento con medicamentos estimulantes durante el estudio. Para evaluar la especificidad de la asociación TDAHâ TEPT, examinamos las asociaciones entre el TDAH previo al despliegue, el episodio depresivo mayor posterior al despliegue (EDM), el trastorno de ansiedad generalizada (TAG), y la ideación suicida. La prevalencia ponderada del TDAH previo al despliegue fue de 6.1% (SE = 0.4%). Al controlar los otros factores de riesgo, el TDAH previo al despliegue se asoció con el riesgo de TEPT posterior al despliegue, odds ratio ajustado (AOR en su sigla en inglés) = 2.13, IC del 95% [1.51, 3.00], p <.001, incluida la incidencia entre soldados sin historial previo al despliegue de TEPT, AOR = 2.50, IC del 95% [1.69, 3.69], p <.001. El TDAH se asoció con el EDM posterior al despliegue, AOR = 2.80, IC del 95% [2.01, 3.91], p <.001, y TAG, AOR = 3.04, IC del 95% [2.10, 4.42], p <.001, pero no con ideación suicida. El reconocimiento de las asociaciones entre el TDAH previo al despliegue y el TEPT, el EDM, y el TAG posterior al despliegue puede informar los esfuerzos de prevención específicos. Las investigaciones futuras deberían examinar si el tratamiento del TDAH protege contra el TEPT y los trastornos relacionados en personas expuestas a trauma.æ ½è±¡Traditional and Simplified Chinese Abstracts by the Asian Society for Traumatic Stress Studies (AsianSTSS)ç°¡é« å ç¹ é« ä¸­æ æ ®è¦ ç ±äº æ´²å µå ·å¿ ç ç  ç©¶å­¸æ 翻譯Attention Deficit Hyperactivity Disorder and Risk of Posttraumatic Stress and Related Disorders: A Prospective Longitudinal Evaluation in US Army SoldiersTraditional Chineseæ¨ é¡ : å° æ³¨å ä¸ è¶³æ é åº¦æ´»èº ç è æ £å µå ·å¾ å£ å ç å ç ¸é ç ¾ç ç é¢¨é ª:å° ç¾ å è» äººé ²è¡ ç å ç »ç¸±è²«ç  ç©¶æ ®è¦ : é å¾ ä¸ ç ´æ ç  ç©¶æª¢è¦ å° æ³¨å ä¸ è¶³æ é åº¦æ´»èº ç (ADHD)è å µå ·å¾ å£ å ç (PTSD)ä¹ é ç æ©«æ ·æ §é é £, å ¯æ ¯, æ å ä» æ¬ ç¼ºæª¢è¦ å ©è é é £ç ç¸±è²«ç  ç©¶ã æ ¬å ç »ç  ç©¶æ ¨å ¨é é ç¾ è» æ¨£æ ¬, è© ä¼°æ å½¹å ADHDè· æ å½¹å¾ PTSDç é é £ã æ¨£æ ¬ç ºå å¾ é ¿å¯ æ± æ å½¹ç è» äºº, å ¨æ å½¹å (T0)å å® æ æ å½¹å¾ ç´ 1å æ (T1)ã 3å æ (T2)å 9å æ (T3)æ ¥å èª¿æ ¥ã æ å 以é 輯迴歸å æ å æ æ 波段ç æ ¸æ , ä¼°è¨ 4,612å è» äººæ å½¹å ADHDè· æ å½¹å¾ (T2 æ T3)PTSDç é é £ã ç  ç©¶ä¸­, æ¨£æ ¬ä¸¦ç ¡æ ç ¨è å¥®è ¥ç ©ã ç ºäº è§£ADHDâ PTSDç ç ¹æ® é é £, æ å æª¢è¦ ä»¥ä¸ é  ç ®ä¹ é ç é é £:æ å½¹å ADHDã å® æ æ å½¹å¾ ç å ´é æ é¬±ç¯ æ®µ(MDE)ã å»£æ³ æ §ç ¦æ ®ç (GAD)ã è ªæ®ºæ 念ã æ å½¹å ADHDæ ®é åº¦ç º6.1% (SE = 0.4%)ã å° å ¶ä» é¢¨é ªå  ç´ ä½ èª¿ç¯ å¾ , æ å½¹å ADHDè· æ å½¹å¾ æ £PTSDç é¢¨é ªæ æ é é £(å·²èª¿ç¯ å ç® æ¯ (AOR) = 2.13, 95% CI [1.51, 3.00], p < .001), ç ¶ä¸­å æ ¬æ å½¹å ä¸¦ç ¡PTSDç è» äºº(AOR = 2.50, 95% CI [1.69, 3.69], p < .001)ã ADHDè· å® æ æ å½¹å¾ æ £MDEç (AOR = 2.80, 95% CI [2.01, 3.91], p < .001)å GAD(AOR = 3.04, 95% CI [2.10, 4.42] p < .001)é ½æ é , ä½ è· è ªæ®ºæ å¿µç ¡é ã äº è§£æ å½¹å ADHDè· æ å½¹å¾ PTSDã MDEå GADç é é £, å ¯è ½æ å ©ç ¼å± é å° æ §ç é  é ²å·¥ä½ ã æ ªä¾ ç  ç©¶æ æª¢è¦ å° å å µäººå£«æ ä¾ ADHDæ²»ç , æ ¯å ¦å° å ¶PTSDå ç ¸é ç ¾ç æ ä¿ è­·æ æ ã Simplified Chineseæ  é¢ : ä¸ æ³¨å ä¸ è¶³æ è¿ åº¦æ´»è· ç ä¸ æ £å 伤å å å ç å ç ¸å ³ç ¾ç ç é£ é ©:å¯¹ç¾ å ½å äººè¿ è¡ ç å ç »çºµè´¯ç  ç©¶æ ®è¦ : è¿ å¾ ä¸ ç ´æ ç  ç©¶æ£ è§ ä¸ æ³¨å ä¸ è¶³æ è¿ åº¦æ´»è· ç (ADHD)ä¸ å 伤å å å ç (PTSD)ä¹ é ´ç æ¨ªæ ­æ §å ³è¿ , å ¯æ ¯, æ ä»¬ä» æ¬ ç¼ºæ£ è§ ä¸¤è å ³è¿ ç çºµè´¯ç  ç©¶ã æ ¬å ç »ç  ç©¶æ ¨å ¨é è¿ ç¾ å æ ·æ ¬, è¯ ä¼°æ å½¹å ADHDè· æ å½¹å PTSDç å ³è¿ ã æ ·æ ¬ä¸ºå å¾ é ¿å¯ æ± æ å½¹ç å 人, å ¨æ å½¹å (T0)å å® æ æ å½¹å 约1个æ (T1)ã 3个æ (T2)å 9个æ (T3)æ ¥å è° æ ¥ã æ ä»¬ä»¥é »è¾ å å½ å æ å æ æ 波段ç æ °æ ®, 估计4,612å å 人æ å½¹å ADHDè· æ å½¹å (T2 æ T3)PTSDç å ³è¿ ã ç  ç©¶ä¸­, æ ·æ ¬å¹¶æ  æ ç ¨å ´å¥ è ¯ç ©ã ä¸ºäº è§£ADHDâ PTSDç ç ¹æ® å ³è¿ , æ ä»¬æ£ è§ ä»¥ä¸ é¡¹ç ®ä¹ é ´ç å ³è¿ :æ å½¹å ADHDã å® æ æ å½¹å ç 严é æ é è 段(MDE)ã å¹¿æ³ æ §ç ¦è ç (GAD)ã è ªæ æ 念ã æ å½¹å ADHDæ ®é 度为6.1% (SE = 0.4%)ã å¯¹å ¶ä» é£ é ©å  ç´ ä½ è° è å , æ å½¹å ADHDè· æ å½¹å æ £PTSDç é£ é ©æ æ å ³è¿ (å·²è° è è ç® æ¯ (AOR) = 2.13, 95% CI [1.51, 3.00], p < .001), å½ ä¸­å æ ¬æ å½¹å å¹¶æ  PTSDç å 人(AOR = 2.50, 95% CI [1.69, 3.69], p < .001)ã ADHDè· å® æ æ å½¹å æ £MDEç (AOR = 2.80, 95% CI [2.01, 3.91], p < .001)å GAD(AOR = 3.04, 95% CI [2.10, 4.42] p < .001)é ½æ å ³, ä½ è· è ªæ æ å¿µæ  å ³ã äº è§£æ å½¹å ADHDè· æ å½¹å PTSDã MDEå GADç å ³è¿ , å ¯è ½æ å ©å å± é å¯¹æ §ç é¢ é ²å·¥ä½ ã æ ªæ ¥ç  ç©¶åº æ£ è§ å¯¹å å 人士æ ä¾ ADHDæ²»ç , æ ¯å ¦å¯¹å ¶PTSDå ç ¸å ³ç ¾ç æ ä¿ æ ¤æ åº ãPeer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146971/1/jts22347_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146971/2/jts22347.pd

Identifying future models for delivering genetic services: a nominal group study in primary care

BACKGROUND: To enable primary care medical practitioners to generate a range of possible service delivery models for genetic counselling services and critically assess their suitability. METHODS: Modified nominal group technique using in primary care professional development workshops. RESULTS: 37 general practitioners in Wales, United Kingdom too part in the nominal group process. The practitioners who attended did not believe current systems were sufficient to meet anticipated demand for genetic services. A wide range of different service models was proposed, although no single option emerged as a clear preference. No argument was put forward for genetic assessment and counselling being central to family practice, neither was there a voice for the view that the family doctor should become skilled at advising patients about predictive genetic testing and be able to counsel patients about the wider implications of genetic testing for patients and their family members, even for areas such as common cancers. Nevertheless, all the preferred models put a high priority on providing the service in the community, and often co-located in primary care, by clinicians who had developed expertise. CONCLUSION: There is a need for a wider debate about how healthcare systems address individual concerns about genetic concerns and risk, especially given the increasing commercial marketing of genetic tests

Treatment outcomes 24 months after initiating short, all-oral bedaquiline-containing or injectable-containing rifampicin-resistant tuberculosis treatment regimens in South Africa : a retrospective cohort study

DATA SHARING : The data used for this analysis in the form of deidentified participant data and a data dictionary will be made available after publication. Investigators wishing to access these data will need to have an approved research proposal and complete a data access agreement. All inquiries should be sent to the corresponding author ([email protected] or [email protected]).SUPPLEMENTARY MATERIAL 1 : French translation of the abstract. SUPPLEMENTARY MATERIAL 2 : Appendices.BACKGROUND : There is a need for short and safe all-oral treatment of rifampicin-resistant tuberculosis. We compared outcomes up to 24 months after treatment initiation for patients with rifampicin-resistant tuberculosis in South Africa treated with a short, all-oral bedaquiline-containing regimen (bedaquiline group), or a short, injectable-containing regimen (injectable group). METHODS : Patients with rifampicin-resistant tuberculosis, aged 18 years or older, eligible for a short regimen starting treatment between Jan 1 and Dec 31, 2017, with a bedaquiline-containing or WHO recommended injectable-containing treatment regimen of 9–12 months, registered in the drug-resistant tuberculosis database (EDRWeb), and with known age, sex, HIV status, and national identification number were eligible for study inclusion; patients receiving linezolid, carbapenems, terizidone or cycloserine, delamanid, or para-aminosalicylic acid were excluded. Bedaquiline was given at a dose of 400 mg once daily for two weeks followed by 200 mg three times a week for 22 weeks. To compare regimens, patients were exactly matched on HIV and ART status, previous tuberculosis treatment history, and baseline acid-fast bacilli smear and culture result, while propensity score matched on age, sex, province of treatment, and isoniazid-susceptibility status. We did binomial linear regression to estimate adjusted risk differences (aRD) and 95% CIs for 24-month outcomes, which included: treatment success (ie, cure or treatment completion without evidence of recurrence) versus all other outcomes, survival versus death, disease free survival versus survival with treatment failure or recurrence, and loss to follow-up versus all other outcomes. FINDINGS : Overall, 1387 (14%) of 10152 patients with rifampicin-resistant tuberculosis treated during 2017 met inclusion criteria; 688 in the bedaquiline group and 699 in the injectable group. Four patients (1%) had treatment failure or recurrence, 44 (6%) were lost to follow-up, and 162 (24%) died in the bedaquiline group, compared with 17 (2%), 87 (12%), and 199 (28%), respectively, in the injectable group. In adjusted analyses, treatment success was 14% (95% CI 8–20) higher in the bedaquiline group than in the injectable group (70% vs 57%); loss to follow-up was 4% (1–8) lower in the bedaquiline group (6% vs 12%); and disease-free survival was 2% (0–5) higher in the bedaquiline group (99% vs 97%). The bedaquiline group had 8% (4–11) lower risk of mortality during treatment (17·0% vs 22·4%), but there was no difference in mortality post-treatment. INTERPRETATION : Patients in the bedaquiline group experienced significantly higher rates of treatment success at 24 months. This finding supports the use of short bedaquiline-containing regimens in eligible patients.WHO Global TB Programme.http://www.thelancet.com/infectionhj2023Medical Microbiolog

Identifying patients with multidrug-resistant tuberculosis who may benefit from shorter durations of treatment.

ObjectiveStudying treatment duration for rifampicin-resistant and multidrug-resistant tuberculosis (MDR/RR-TB) using observational data is methodologically challenging. We aim to present a hypothesis generating approach to identify factors associated with shorter duration of treatment.Study design and settingWe conducted an individual patient data meta-analysis among MDR/RR-TB patients restricted to only those with successful treatment outcomes. Using multivariable linear regression, we estimated associations and their 95% confidence intervals (CI) between the outcome of individual deviation in treatment duration (in months) from the mean duration of their treatment site and patient characteristics, drug resistance, and treatments used.ResultsOverall, 6702 patients with successful treatment outcomes from 84 treatment sites were included. We found that factors commonly associated with poor treatment outcomes were also associated with longer treatment durations, relative to the site mean duration. Use of bedaquiline was associated with a 0.51 (95% CI: 0.15, 0.87) month decrease in duration of treatment, which was consistent across subgroups, while MDR/RR-TB with fluoroquinolone resistance was associated with 0.78 (95% CI: 0.36, 1.21) months increase.ConclusionWe describe a method to assess associations between clinical factors and treatment duration in observational studies of MDR/RR-TB patients, that may help identify patients who can benefit from shorter treatment

Chest X-ray Analysis With Deep Learning-Based Software as a Triage Test for Pulmonary Tuberculosis: An Individual Patient Data Meta-Analysis of Diagnostic Accuracy.

BACKGROUND: Automated radiologic analysis using computer-aided detection software (CAD) could facilitate chest X-ray (CXR) use in tuberculosis diagnosis. There is little to no evidence on the accuracy of commercially available deep learning-based CAD in different populations, including patients with smear-negative tuberculosis and people living with human immunodeficiency virus (HIV, PLWH). METHODS: We collected CXRs and individual patient data (IPD) from studies evaluating CAD in patients self-referring for tuberculosis symptoms with culture or nucleic acid amplification testing as the reference. We reanalyzed CXRs with three CAD programs (CAD4TB version (v) 6, Lunit v3.1.0.0, and qXR v2). We estimated sensitivity and specificity within each study and pooled using IPD meta-analysis. We used multivariable meta-regression to identify characteristics modifying accuracy. RESULTS: We included CXRs and IPD of 3727/3967 participants from 4/7 eligible studies. 17% (621/3727) were PLWH. 17% (645/3727) had microbiologically confirmed tuberculosis. Despite using the same threshold score for classifying CXR in every study, sensitivity and specificity varied from study to study. The software had similar unadjusted accuracy (at 90% pooled sensitivity, pooled specificities were: CAD4TBv6, 56.9% [95% confidence interval {CI}: 51.7-61.9]; Lunit, 54.1% [95% CI: 44.6-63.3]; qXRv2, 60.5% [95% CI: 51.7-68.6]). Adjusted absolute differences in pooled sensitivity between PLWH and HIV-uninfected participants were: CAD4TBv6, -13.4% [-21.1, -6.9]; Lunit, +2.2% [-3.6, +6.3]; qXRv2: -13.4% [-21.5, -6.6]; between smear-negative and smear-positive tuberculosis was: were CAD4TBv6, -12.3% [-19.5, -6.1]; Lunit, -17.2% [-24.6, -10.5]; qXRv2, -16.6% [-24.4, -9.9]. Accuracy was similar to human readers. CONCLUSIONS: For CAD CXR analysis to be implemented as a high-sensitivity tuberculosis rule-out test, users will need threshold scores identified from their own patient populations and stratified by HIV and smear status

Coronary volume to left ventricular mass ratio in patients with diabetes mellitus

BackgroundDiabetes mellitus is a major risk factor for coronary artery disease (CAD) and may provoke structural and functional changes in coronary vasculature. The coronary volume to left ventricular mass (V/M) ratio is a new anatomical parameter capable of revealing a potential physiological imbalance between coronary vasculature and myocardial mass. The aim of this study was to examine the V/M derived from coronary computed tomography angiography (CCTA) in patients with diabetes.MethodsPatients with clinically suspected CAD enrolled in the ADVANCE (Assessing Diagnostic Value of Non-invasive FFRCT in Coronary Care) registry and known diabetic status were included. Coronary artery volume and left ventricular myocardial mass were analyzed from CCTA and the V/M ratio was calculated and compared between patients with and without diabetes.ResultsOf the 3053 patients (age 66 ​± ​10 years; 66% male) with known diabetic status, diabetes was present in 21.9%. Coronary volume was lower in patients with diabetes compared to those without diabetes (2850 ​± ​940 ​mm3 vs. 3040 ​± ​970 ​mm3, p ​ConclusionThe V/M ratio was significantly lower in patients with diabetes compared to non-diabetics, even after correcting for obstructive coronary stenosis. The clinical value of the reduced V/M ratio in diabetic patients needs further investigation.</p

The Australasian Resuscitation In Sepsis Evaluation : fluids or vasopressors in emergency department sepsis (ARISE FLUIDS), a multi-centre observational study describing current practice in Australia and New Zealand

Objectives: To describe haemodynamic resuscitation practices in ED patients with suspected sepsis and hypotension. Methods: This was a prospective, multicentre, observational study conducted in 70 hospitals in Australia and New Zealand between September 2018 and January 2019. Consecutive adults presenting to the ED during a 30-day period at each site, with suspected sepsis and hypotension (systolic blood pressure <100 mmHg) despite at least 1000 mL fluid resuscitation, were eligible. Data included baseline demographics, clinical and laboratory variables and intravenous fluid volume administered, vasopressor administration at baseline and 6- and 24-h post-enrolment, time to antimicrobial administration, intensive care admission, organ support and in-hospital mortality. Results: A total of 4477 patients were screened and 591 were included with a mean (standard deviation) age of 62 (19) years, Acute Physiology and Chronic Health Evaluation II score 15.2 (6.6) and a median (interquartile range) systolic blood pressure of 94 mmHg (87–100). Median time to first intravenous antimicrobials was 77 min (42–148). A vasopressor infusion was commenced within 24 h in 177 (30.2%) patients, with noradrenaline the most frequently used (n = 138, 78%). A median of 2000 mL (1500–3000) of intravenous fluids was administered prior to commencing vasopressors. The total volume of fluid administered from pre-enrolment to 24 h was 4200 mL (3000–5661), with a range from 1000 to 12 200 mL. Two hundred and eighteen patients (37.1%) were admitted to an intensive care unit. Overall in-hospital mortality was 6.2% (95% confidence interval 4.4–8.5%). Conclusion: Current resuscitation practice in patients with sepsis and hypotension varies widely and occupies the spectrum between a restricted volume/earlier vasopressor and liberal fluid/later vasopressor strategy

Returns to Investors in Stocks in New Industries

We examine the returns to investors in publicly traded stock in new industries. We examine data from the United States on sellers of own-brand personal computers, airlines and airplane manufacturers, automobile manufacturers, railroads, and telegraphs. We find that a relatively small number of companies generate outstanding returns and many firms fail. Firms in new industries typically have high volatility of individual stocks' returns. Compared with indexes for the same period, expected returns of firms are higher for two industries, lower for one industry and roughly the same for two industries. Portfolios of firms in new industries generally have lower Sharpe ratios than the overall market

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms
