- Objective: The aim of this clinical trial is to examine whether it is possible to reduce postoperative complications using an individualized perioperative ventilatory strategy versus using a standard lung-protective ventilation strategy in patients scheduled for thoracic surgery requiring one-lung ventilation. Design: International, multicenter, prospective, randomized controlled clinical trial. Setting: A network of university hospitals. Participants: The study comprises 1,380 patients scheduled for thoracic surgery. Interventions: The individualized group will receive intraoperative recruitment maneuvers followed by individualized positive end-expiratory pressure (open lung approach) during the intraoperative period plus postoperative ventilatory support with high-flow nasal cannula, whereas the control group will be managed with conventional lung-protective ventilation. Measurements and Main Results: Individual and total number of postoperative complications, including atelectasis, pneumothorax, pleural effusion, pneumonia, acute lung injury; unplanned readmission and reintubation; length of stay and death in the critical care unit and in the hospital will be analyzed for both groups. The authors hypothesize that the intraoperative application of an open lung approach followed by an individual indication of high-flow nasal cannula in the postoperative period will reduce pulmonary complications and length of hospital stay in high-risk surgical patients.

- Experimenting is fundamental to the training process of all scientists and engineers. While experiments have been traditionally done inside laboratories, the emergence of Information and Communication Technologies added two alternatives accessible anytime, anywhere. These two alternatives are known as virtual and remote laboratories and are sometimes indistinguishably referred as online laboratories. Similarly to other instructional technologies, virtual and remote laboratories require some effort from teachers in integrating them into curricula, taking into consideration several factors that affect their adoption (i.e., cost) and their educational effectiveness (i.e., benefit). This chapter analyzes these two dimensions and sustains the case where only through international cooperation it is possible to serve the large number of teachers and students involved in engineering education. It presents an example in the area of electrical and electronics engineering, based on a remote laboratory named Virtual Instruments System in Reality, and it then describes how a number of European and Latin American institutions have been cooperating under the scope of an Erasmus+ project, for spreading its use in Brazil and Argentina.

- 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.

- While antidepressant use during pregnancy has been associated with adverse birth and neurodevelopmental outcomes, these associations may be attributed to confounding factors, such as genetic influences, maternal stress, or poor health practices during pregnancy. This study used 4 observational designs to investigate these associations, including sibling and paternal information.The study used multiple national Swedish registries. First-trimester exposures, defined as at least 1 dispensation between 90 days before estimated conceptions and 90 days after estimated conception, to any antidepressants and selective serotonin reuptake inhibitors, reported through either maternal self-report or dispensation records, were the main exposures evaluated. The main outcomes were small for gestational age, defined as birth weight less than 2 SDs below the mean for gestational age; preterm birth, defined as less than 37 gestational weeks; and diagnosis of autism spectrum disorder or attention-deficit/hyperactivity disorder (ADHD). Maternal and paternal covariates included age of childbearing, highest level of completed education, history of criminal conviction, history of psychiatric illnesses, history of suicide attempts, and country of origin (Sweden or outside Sweden). Parity and year of birth were pregnancy covariates. Population-wide baseline models were assessed adjusting only for pregnancy covariates. Then, population-wide associations were adjusted for maternal and paternal covariates as well. A third model compared exposure-and outcome-discordant offspring within families.After exclusion of multiple births, missing father identifiers, or other missing information, a final cohort of 1,580,629 offspring born to 943,776 was used. Of these, 26,477 offspring had first-trimester maternal antidepressant dispensations, 22,125 of which were selective serotonin reuptake inhibitor dispensations. Preterm births accounted for 6.98% of exposed and 4.78% of unexposed offspring. In the baseline models, first-trimester exposure was associated with all 4 outcomes (preterm birth odds ratio [OR], 1.47; 95% confidence interval [CI], 1.40-1.55]; small for gestational age OR, 1.15 [95% CI, 1.06-1.25]; ADHD HR, 2.21 [95% CI, 2.04-2.39]). After adjusting for pregnancy and maternal and paternal traits and comparing sibling data, first-trimester antidepressant exposure was associated with only a small increased risk of preterm birth (OR, 1.34 [95% CI, 1.18-1.52]) and was not associated with small for gestational age (OR, 1.01 [95% CI, 0.81-1.25]), ADHD (HR, 0.99 [95% CI, 0.79-1.25]), or autism spectrum disorder (HR, 0.83 [95% CI, 0.62-1.13]).Unexposed and exposed siblings were found to be at equal risk of small for gestational age, ADHD, and autism spectrum disorder as one another, whereas exposed siblings had a slightly increased risk of preterm birth. Both autism spectrum disorder and ADHD were associated with paternal first-trimester antidepressant dispensations, supporting the idea that familial confounding may explain associations between exposure and neurodevelopmental disorders.

- Individuals conceived with assisted reproductive techniques (ARTs) could be at elevated risk of psychiatric disorders owing to potential adverse effects of the procedures themselves, or because such traits or their risk factors may be more common in couples with infertility.To investigate the risk of psychiatric disorders in adolescents and young adults conceived with ARTs and to evaluate the role of treatment-related parental characteristics.This prospective follow-up of a nationwide birth cohort used linkage of Swedish population registers with coverage through 2018. All children born in Sweden from January 1, 1994, to December 31, 2006, were included in the analysis. Follow-up was completed on December 31, 2018, when participants were 12 to 25 years of age, and data was analyzed from March 17, 2020, to September 10, 2021.In vitro fertilization with or without intracytoplasmic sperm injection and transfer of fresh or frozen-thawed embryos.Clinical diagnoses of mood disorder, including major depression, anxiety, obsessive-compulsive disorder (OCD), or suicidal behavior, were identified from hospital records and outpatient specialist care. Suicide was additionally identified from death certificates. Antidepressant use was identified from dispensations of prescribed medications.A total of 1221812 children (48.6% female, 51.4% male) born between 1994 and 2006 were followed up to a median age of 18 (IQR, 15-21) years. Among these participants, 31565 (2.6%) were conceived with ART. Compared with all others, adolescents conceived with ART had an elevated risk of OCD (hazard ratio [HR],1.35 [95% CI, 1.20-1.51]), but the association was attenuated and no longer statistically significant after adjustment for parental characteristics (adjusted HR [aHR], 1.10 [95% CI, 0.98-1.24]) and was no longer present when restricted to individuals born to couples with known infertility (aHR, 1.02 [95% CI, 0.89-1.17]). Adolescents conceived with ARTs were not at elevated risk of depression or suicidal behavior compared with other adolescents (irrespective of parental infertility). Type of fertilization (standard in vitro fertilization or intracytoplasmic sperm injection) had no association with outcomes. Compared with non-ART-conceived children of couples with infertility, fresh, but not frozen, embryo transfer was associated with a lower risk of mood disorders (aHR, 0.90 [95% CI, 0.83-0.97]), making frozen embryo transfer appear less advantageous when directly contrasted with fresh embryo transfer.These findings suggest that adolescents conceived with ARTs around the millennium are not at risk of poor psychiatric health compared with the general population, except for an elevated risk of OCD that may be explained by differences in parental characteristics.

- The current study examined associations between labor induction and both (1) offspring attention-deficit hyperactivity disorder (ADHD) diagnosis in a Swedish birth cohort born 1992-2005 (n = 1,085,008) and (2) indices of offspring low academic achievement in a sub-cohort born 1992-1997 (n = 489,196). Associations were examined in the entire sample (i.e., related and unrelated individuals) with adjustment for measured covariates and, in order to account for unmeasured confounders shared within families, within differentially exposed cousins and siblings. We observed an association between labor induction and offspring ADHD diagnosis and low academic achievement in the population. However, these associations were fully attenuated after adjusting for measured covariates and unmeasured factors that cousins and siblings share. The results suggest that observed associations between labor induction and ADHD and low academic achievement may be due to genetic and/or shared environmental factors that influence both mothers' risk of labor induction and offspring neurodevelopment.

- IMPORTANCE: Induction of labor is a frequently performed obstetrical intervention. It would thus be of great concern if reported associations between labor induction and offspring risk of autism spectrum disorders (ASD) reflected causal influence. OBJECTIVE: To assess the associations of labor induction with ASD, comparing differentially exposed relatives (siblings and cousins discordant for induction). DESIGN, SETTING, AND PARTICIPANTS: Follow-up of all live births in Sweden between 1992 and 2005, defined in the Medical Birth Register. The register was linked to population registers of familial relations, inpatient and outpatient visits, and education records. Diagnoses of ASD were from 2001 through 2013, and data were analyzed in the 2015-2016 year. EXPOSURES: Induction of labor. MAIN OUTCOMES AND MEASURES: Autism spectrum disorders identified by diagnoses from inpatient and outpatient records between 2001 and 2013. Hazard ratios (HRs) quantified the association between labor induction and offspring ASD. In addition to considering a wide range of measured confounders, comparison of exposure-discordant births to the same woman allowed additional control for all unmeasured factors shared by siblings. RESULTS: The full cohort included 1362950 births, of which 22077 offspring (1.6%) were diagnosed with ASD by ages 8 years through 21 years. In conventional models of the full cohort, associations between labor induction and offspring ASD were attenuated but remained statistically significant after adjustment for measured potential confounders (HR, 1.19; 95% CI, 1.13-1.24). When comparison was made within siblings whose births were discordant with respect to induction, thus accounting for all environmental and genetic factors shared by siblings, labor induction was no longer associated with offspring ASD (HR, 0.99; 95% CI, 0.88-1.10). CONCLUSIONS AND RELEVANCE: In this nationwide sample of live births we observed no association between induction of labor and offspring ASD within sibling comparison. Our findings suggest that concern for ASD should not factor into the clinical decision about whether to induce labor.
