- IMPORTANCE: Cohort studies, mainly based on questionnaires and interviews, have reported high rates of reflux recurrence after antireflux surgery, which may have contributed to a decline in its use. Reflux recurrence after laparoscopic antireflux surgery has not been assessed in a long-term population-based study of unselected patients. OBJECTIVES: To determine the risk of reflux recurrence after laparoscopic antireflux surgery and to identify risk factors for recurrence. DESIGN AND SETTING: Nationwide population-based retrospective cohort study in Sweden between January 1, 2005, and December 31, 2014, based on all Swedish health care and including 2655 patients who underwent laparoscopic antireflux surgery according to the Swedish Patient Registry. Their records were linked to the Swedish Causes of Death Registry and Prescribed Drug Registry. EXPOSURES: Primary laparoscopic antireflux surgery due to gastroesophageal reflux disease in adults (>18 years). MAIN OUTCOMES AND MEASURES: The outcomewas recurrence of reflux, defined as use of antireflux medication (proton pump inhibitors or histamine2 receptor antagonists for >6 months) or secondary antireflux surgery. Multivariable Cox regression was used to assess risk factors for reflux recurrence. RESULTS: Among all 2655 patients who underwent antireflux surgery (median age, 51.0 years; interquartile range, 40.0-61.0 years; 1354 men [51.0%]) and were followed up for a median of 5.6 years, 470 patients (17.7%) had reflux recurrence; 393 (83.6%) received long-term antireflux medication and 77 (16.4%) underwent secondary antireflux surgery. Risk factors for reflux recurrence included female sex (hazard ratio [HR], 1.57 [95%CI, 1.29-1.90]; 286 of 1301 women [22.0%] and 184 of 1354 men [13.6%] had recurrence of reflux), older age (HR, 1.41 [95%CI, 1.10-1.81] for age 61 years compared with 45 years; recurrence among 156 of 715 patients and 133 of 989 patients, respectively), and comorbidity (HR, 1.36 [95%CI, 1.13-1.65] for Charlson comorbidity index score 1 compared with 0; recurrence among 180 of 804 patients and 290 of 1851 patients, respectively). Hospital volume of antireflux surgery was not associated with risk of reflux recurrence (HR, 1.09 [95%CI, 0.77-1.53] for hospital volume 24 surgeries compared with 76 surgeries; recurrence among 38 of 266 patients [14.3%] and 271 of 1526 patients [17.8%], respectively). CONCLUSIONS AND RELEVANCE: Among patients who underwent primary laparoscopic antireflux surgery, 17.7%experienced recurrent gastroesophageal reflux requiring long-term medication use or secondary antireflux surgery. Risk factors for recurrence were older age, female sex, and comorbidity. Laparoscopic antireflux surgery was associated with a relatively high rate of recurrent gastroesophageal reflux disease requiring treatment, diminishing some of the benefits of the operation.

- Importance: Prenatal antidepressant exposure has been associated with adverse outcomes. Previous studies, however, may not have adequately accounted for confounding. Objective: To evaluate alternative hypotheses for associations between first-trimester antidepressant exposure and birth and neurodevelopmental problems. Design, Setting, and Participants: This retrospective cohort study included Swedish offspring born between 1996 and 2012 and followed up through 2013 or censored by death or emigration. Analyses controlling for pregnancy, maternal and paternal covariates, as well as sibling comparisons, timing of exposure comparisons, and paternal comparisons, were used to examine the associations. Exposures: Maternal self-reported first-trimester antidepressant use and first-trimester antidepressant dispensations. Main Outcomes and Measures: Preterm birth (<37 gestational weeks), small for gestational age (birth weight <2 SDs below the mean for gestational age), and first inpatient or outpatient clinical diagnosis of autism spectrum disorder and attention-deficit/hyperactivity disorder in offspring. Results: Among 1580629 offspring (mean gestational age, 279 days; 48.6% female; 1.4% [n = 22544] with maternal first-trimester self-reported antidepressant use) born to 943776 mothers (mean age at childbirth, 30 years), 6.98% of exposed vs 4.78% of unexposed offspring were preterm, 2.54% of exposed vs 2.19% of unexposed were small for gestational age, 5.28% of exposed vs 2.14% of unexposed were diagnosed with autism spectrum disorder by age 15 years, and 12.63% of exposed vs 5.46% of unexposed were diagnosed with attention-deficit/hyperactivity disorder by age 15 years. At the population level, first-trimester exposure was associated with all outcomes compared with unexposed offspring (preterm birth odds ratio [OR], 1.47 [95% CI, 1.40-1.55]; small for gestational age OR, 1.15 [95% CI, 1.06-1.25]; autism spectrum disorder hazard ratio [HR], 2.02 [95% CI, 1.80-2.26]; attention-deficit/hyperactivity disorder HR, 2.21 [95% CI, 2.04-2.39]). However, in models that compared siblings while adjusting for pregnancy, maternal, and paternal traits, first-trimester antidepressant exposure was associated with preterm birth (OR, 1.34 [95% CI, 1.18-1.52]) but not with small for gestational age (OR, 1.01 [95% CI, 0.81-1.25]), autism spectrum disorder (HR, 0.83 [95% CI, 0.62-1.13]), or attention-deficit/hyperactivity disorder (HR, 0.99 [95% CI, 0.79-1.25]). Results from analyses assessing associations with maternal dispensations before pregnancy and with paternal first-trimester dispensations were consistent with findings from the sibling comparisons. Conclusions and Relevance: Among offspring born in Sweden, after accounting for confounding factors, first-trimester exposure to antidepressants, compared with no exposure, was associated with a small increased risk of preterm birth but no increased risk of small for gestational age, autism spectrum disorder, or attention-deficit/hyperactivity disorder.

- Key PointsQuestionIs internet-delivered cognitive behavioral therapy (CBT) implemented in a stepped-care model noninferior to in-person CBT for children and adolescents with obsessive-compulsive disorder? FindingsIn this randomized, noninferiority clinical trial, 152 children and adolescents with obsessive-compulsive disorder were treated with an internet-delivered CBT program followed by traditional in-person CBT if necessary vs in-person CBT alone. After 6 months, the mean Children's Yale-Brown Obsessive-Compulsive Scale score was 11.57 in those treated with internet-delivered CBT vs 10.57 in those treated with in-person CBT, a difference that met the noninferiority criterion of 4 points. MeaningTreating children and adolescents with obsessive-compulsive disorder with an internet intervention followed by traditional face-to-face therapy if necessary was noninferior to in-person therapy alone. ImportanceIn most countries, young people with obsessive-compulsive disorder have limited access to specialist cognitive behavioral therapy (CBT), a first-line treatment. ObjectiveTo investigate whether internet-delivered CBT implemented in a stepped-care model is noninferior to in-person CBT for pediatric obsessive-compulsive disorder. Design, Setting and ParticipantsA randomized clinical noninferiority trial conducted at 2 specialist child and adolescent mental health clinics in Sweden. Participants included 152 individuals aged 8 to 17 years with obsessive-compulsive disorder. Enrollment began in October 2017 and ended in May 2019. Follow-up ended in April 2020. InterventionsParticipants randomized to the stepped-care group (n=74) received internet-delivered CBT for 16 weeks. Nonresponders at the 3-month follow-up were then offered a course of traditional face-to-face treatment. Participants randomized to the control group (n=78) immediately received in-person CBT for 16 weeks. Nonresponders at the 3-month follow-up received additional face-to-face treatment. Main Outcomes and MeasuresThe primary outcome was the masked assessor-rated Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) score at the 6-month follow-up. The scale includes 10 items rated from 0(no symptoms) to 4(extreme symptoms), yielding a total score range of 0 to 40, with higher scores indicating greater severity. Assessors were masked to treatment allocation at pretreatment, posttreatment, 3-month follow-up, and 6-month follow-up assessments. The predefined noninferiority margin was 4 points on the CY-BOCS. ResultsAmong the 152 randomized participants (mean age, 13.4 years; 94 [62%] females), 151 (99%) completed the trial. At the 3-month follow-up, 34 participants (46%) in the stepped-care group and 23 (30%) in the in-person CBT group were nonresponders. At the 6-month follow-up, the CY-BOCS score was 11.57 points in the stepped-care group vs 10.57 points in the face-to-face treatment group, corresponding to an estimated mean difference of 0.91 points ([1-sided 97.5% CI, -infinity to 3.28]; P for noninferiority=.02). Increased anxiety (30%-36%) and depressive symptoms (20%-28%) were the most frequently reported adverse events in both groups. There were 2 unrelated serious adverse events (1 in each group). Conclusions and RelevanceAmong children and adolescents with obsessive-compulsive disorder, treatment with an internet-delivered CBT program followed by in-person CBT if necessary compared with in-person CBT alone resulted in a noninferior difference in symptoms at the 6-month follow-up. Further research is needed to understand the durability and generalizability of these findings. Trial RegistrationClinicalTrials.gov Identifier: NCT03263546 This noninferiority trial compares the effects of an internet-delivered cognitive behavioral therapy (CBT) program followed by traditional in-person CBT if necessary vs in-person CBT alone on symptoms of obsessive compulsive disorder (OCD) in children and adolescents.
