ABSTRACT

IMPORTANCE: Good-quality parent-infant interactions have protective effects on infant socio-emotional and behavioral development. These interactions are especially critical for very preterm infants at risk of vulnerabilities related to immaturity. Skin-to-skin contact (SSC) has been found to improve mother-preterm infant interaction behaviors, but few studies exist regarding its benefits when initiated immediately after birth.

OBJECTIVE: To determine the effect of immediate SSC at birth for very preterm infants on mother-infant interaction quality at 4 months of corrected age.

DESIGN, SETTING, AND PARTICIPANTS: This secondary analysis used data from the Immediate Parent-Infant Skin-to-Skin Study (IPISTOSS), a randomized clinical trial conducted between April 1, 2018, and June 30, 2021, at 3 neonatal units in Sweden and Norway. Participants included very preterm infants (28-33 gestational weeks of age) and their parents. Four-month follow-up was concluded in December 2021. Data analyses were performed on March 16 and September 18, 2023.

INTERVENTION: Infants were allocated to standard incubator care or SSC with either parent initiated at birth and continued throughout the first 6 hours after birth.

MAIN OUTCOMES AND MEASURES: The primary outcome was mother-infant interaction quality as measured with the Parent-Child Early Relational Assessment (PCERA), based on video recordings of a 5-minute free-play situation with mother-infant dyads at 4 months of corrected age. A multilevel regression analysis was performed.

RESULTS: This analysis included 71 infants (31 twins [44%]) and 56 mothers. Infants had a mean (SD) gestational age of 31 weeks 3 (1.3) days, and more than half were male (42 [59%]); mothers had a mean (SD) age of 32 (4.9) years. There were 37 infants allocated to standard care and 34 to SSC with either parent after birth. During the first 6 hours after birth, fathers provided more SSC than mothers, with a median (IQR) of 3.25 (2.25-4.5) and 0.75 (0-2.5) hours, respectively. A statistically significant difference in 1 of 5 PCERA subscales (subscale 3: infant positive affect, communicative and social skills) was observed, with higher-quality mother-infant interaction in the SSC group at 4 months (Cohen d = 0.67 [95% CI, 0.17 to 1.17]; P = .01). This effect remained significant when adjusting for primiparity, child sex, and observation setting.

CONCLUSIONS AND RELEVANCE: In this study of the effect of immediate parent-infant SSC after very preterm birth, SSC was beneficial for the mother-infant relationship. These findings suggest that immediate SSC should be supported in the clinical setting.

ABSTRACT

IMPORTANCE: Depression is a leading cause of disability worldwide, and there is increasing interest in nonpharmacological treatments. Auricular acupuncture (AA) is a simple, low-cost, and well-tolerated option, but further studies are needed to establish its efficacy and safety.

OBJECTIVE: To estimate the efficacy and safety of auricular acupuncture as a treatment for depression.

DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial was conducted at 4 university research centers in Brazil, from March to July 2023. Eligible patients were adults aged 18 to 50 years whose score on the Patient Health Questionnaire-9 (PHQ-9) indicated moderate depression (score 10-14) or moderately severe depression (score 15-19). Exclusion criteria included previous application of AA, risk of suicidal ideation, or severe depression (PHQ-9 score >20). An intent-to-treat analysis and modified intent-to-treat analysis were conducted.

INTERVENTION: Participants were randomized into 2 treatment groups, which included specific AA (SA) and nonspecific AA (NSA). Both groups received 12 sessions of AA with semipermanent needles with daily stimulation twice a week over 6 weeks and were followed-up for 3 months. All participants continued with their usual care for ethical reasons. The SA group’s treatment protocol consisted of 6 acupuncture points on the auricular pavilion chosen according to the diagnosis of depression by traditional Chinese medicine (Shenmen, subcortex, heart, lung, liver, and kidney). The NSA group’s acupuncture points were the external ear, the cheek and face area, and 4 nonspecific points in the helix region unassociated with mental health symptoms. A locator device was used to confirm which areas had neuroreactive points.

MAIN OUTCOMES AND MEASURES: The primary outcome was a reduction of at least 50% in the PHQ-9 score (ie, depression recovery) at 3 months. Secondary outcomes included depression recovery at 4 and 6 weeks; depression remission (PHQ-9 score < 5) at 4 weeks, 6 weeks, and 3 months); and adverse events.

RESULTS: A total of 304 participants were screened, and 74 participants (62 women [84%]; median [IQR] age, 29 [23-27] years) were included in the intention-to-treat analysis, with 37 participants randomized to each group (SA and NSA). A total of 47 participants (64%) were followed-up through 3 months. The results showed no statistically significant difference in depressive recovery between the groups at 3 months (14 of 24 participants in the SA group [58%] vs 10 of 23 participants in the NSA group [43%]; risk ratio [RR], 1.34; 95% CI, 0.76-2.45; P = .38). The proportions of depression recovery and remission at 4 and 6 weeks based on the PHQ-9 were higher in the SA group (except for depression recovery at 6 weeks) with no statistically significant differences. However, a statistically significant difference was observed in symptom remission at 3 months (11 of 24 participants in the SA group [46%] vs 3 of 23 participants in the NSA group [13%]; RR, 1.99; 95% CI, 1.16-3.34; P = .02) in favor of SA. There were no significant differences in adverse event rates between the groups, evidencing the intervention’s safety. Most participants reported mild pain at the needle application site (33 patients [94%] in the SA group vs 32 patients [91%] in the NSA group). Five participants dropped out of the study due to adverse events.

CONCLUSIONS AND RELEVANCE: The results of this randomized clinical trial suggest that SA over 6 weeks is safe. Although there was no statistically significant difference between groups for the primary efficacy outcome, patients receiving SA did experience greater symptom remission at 3 months. A larger sample size and longer intervention are needed to further evaluate the efficacy of SA for depression.

ABSTRACT

IMPORTANCE: The association between attention-deficit/hyperactivity disorder (ADHD) and schizophrenia has received increased attention; however, evidence on the association between psychiatric comorbidities and subsequent schizophrenia in patients with ADHD is limited.

OBJECTIVE: To investigate the risk of being diagnosed with schizophrenia in children and adolescents with ADHD considering the presence of psychiatric comorbidity.

DESIGN, SETTING, AND PARTICIPANTS: This was a population-based, retrospective cohort study using the Health Insurance Review and Assessment claims database from January 1, 2007, to December 31, 2019. Participants were children and adolescents aged 5 to 19 years who received an ADHD diagnosis between January 1, 2010, and December 31, 2018, in the nationwide claims data of Korea. Data were analyzed from January 2010 to December 2019.

INTERVENTIONS OR EXPOSURES: The presence of psychiatric comorbidity was assessed from diagnosis records within 1 year before ADHD diagnosis. Comorbidities were further categorized according to the number of comorbidities and specific comorbid disorders.

MAIN OUTCOMES AND MEASURES: Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% CIs, examining the association between psychiatric comorbidities and the risk of being diagnosed with schizophrenia. Furthermore, the occurrence of psychiatric comorbidity during the follow-up period was explored among patients without psychiatric comorbidity at baseline.

RESULTS: A total of 211 705 patients with newly diagnosed ADHD were included. A total of 157 272 patients (74.3%) were male, and the age of 5 to 9 years showed the highest distribution (115 081 patients [54.4%]). Patients with psychiatric comorbidity had a significantly higher risk of being diagnosed with schizophrenia than those without (adjusted HR, 2.14; 95% CI, 2.05-2.23). The association between schizophrenia and psychiatric comorbidity became progressively greater with the increasing number of comorbidities. Several individual psychiatric disorders showed an association with development of schizophrenia, with ASD, intellectual disability, tic disorder, depression, and bipolar disorder being the top 5 disorders most associated. Furthermore, 3244 patients (73.8%) without psychiatric comorbidities experienced the emergence of other psychiatric disorders before schizophrenia occurrence.

CONCLUSIONS AND RELEVANCE: In this retrospective cohort study involving children and adolescents with ADHD, the presence of psychiatric comorbidity in patients with ADHD was associated with an increased risk of being diagnosed with schizophrenia, with an increased risk observed in multiple comorbidities and a wide variety of comorbidities. These findings highlight the significance of assessing and managing psychiatric comorbidities in patients with ADHD to decrease subsequent schizophrenia risk and allow for early intervention.

ABSTRACT

OBJECTIVE: The dissociative subtype of posttraumatic stress disorder (PTSD) was incorporated into the diagnostic criteria for PTSD in Diagnostic and Statisical Manual of Mental Disorders, Fifth Edition (DSM-5). The subtype requires the presence of persistent or recurrent depersonalization or derealization; however, several authors have suggested that a broader array of dissociative symptoms could be included in the criteria. The objective of the present study was to gather data on a wide range of dissociative symptoms in a sample of highly traumatized individuals.

METHOD: The authors administered a set of measures to 62 inpatients in a private psychiatric inpatient program specializing in PTSD and dissociative disorders.

RESULTS: Almost every participant met International Classification of Diseases, 11th Edition criteria for complex PTSD, DSM-5 criteria for the dissociative subtype of PTSD, and DSM-5 criteria for dissociative identity disorder or other specified dissociative disorder; these four diagnoses seem to identify largely the same patients and may not be separate disorders.

CONCLUSIONS: A broad range of dissociative symptoms was endorsed on the Dissociative Experiences Scale and the Dissociative Disorders Interview Schedule. The results support a recommendation that a broad array of symptoms be included in the criteria for the dissociative subtype of PTSD in future editions of the Diagnostic and Statistical Manual of Mental Disorders.

ABSTRACT

OBJECTIVE: Untreated mental disorders are important among low- and middle-income country (LMIC) university students in Latin America, where barriers to treatment are high. Scalable interventions are needed. This study compared transdiagnostic self-guided and guided internet-delivered cognitive behavioral therapy (i-CBT) with treatment as usual (TAU) for clinically significant anxiety and depression among undergraduates in Colombia and Mexico.

METHOD: 1,319 anxious, as determined by the Generalized Anxiety Disorder-7 (GAD-7) = 10+ and/or depressed, as determined by the Patient Health Questionnaire-9 (PHQ-9) = 10+, undergraduates (mean [SD] age = 21.4 [3.2]); 78.7% female; 55.9% first-generation university student) from seven universities in Colombia and Mexico were randomized to culturally adapted versions of self-guided i-CBT (n = 439), guided i-CBT (n = 445), or treatment as usual (TAU; n = 435). All randomized participants were reassessed 3 months after randomization. The primary outcome was remission of both anxiety (GAD-7 = 0-4) and depression (PHQ-9 = 0-4). We hypothesized that remission would be higher with guided i-CBT than with the other interventions.

RESULTS: Intent-to-treat analysis found significantly higher adjusted (for university and loss to follow-up) remission rates (ARD) among participants randomized to guided i-CBT than either self-guided i-CBT (ARD = 13.1%, χ12 = 10.4, p = .001) or TAU (ARD = 11.2%, χ12 = 8.4, p = .004), but no significant difference between self-guided i-CBT and TAU (ARD = -1.9%, χ12 = 0.2, p = .63). Per-protocol sensitivity analyses and analyses of dimensional outcomes yielded similar results.

CONCLUSIONS: Significant reductions in anxiety and depression among LMIC university students could be achieved with guided i-CBT, although further research is needed to determine which students would most likely benefit from this intervention.

ABSTRACT

OBJECTIVE: Technology is changing the way individuals socially connect. However, not much is known about how online forms of social exchanges might link to outcomes that predict longevity. This preregistered study examined the association between online social support and social negativity with self-rated health (SRH) and potential pathways responsible for such links.

METHOD: In this preregistered analysis, a sample of 1,356 U.S. residents was recruited based on the U.S. Census track. Participants were at least 18-year-old social media users and completed the study online. Well-validated measures of online social support, online social negativity, general offline perceived support, internet addiction, social anxiety, and SRH were obtained.

RESULTS: Main results indicate that both online social support and social negativity were related to better SRH. However, the association between social negativity and better SRH was due to its statistical overlap with online social support. The association between online social support and SRH was primarily mediated by offline social support.

CONCLUSIONS: These results highlight the importance of considering how positive and negative online social interactions are related to health outcomes. It also highlights potential pathways that might be targeted for interventions. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

ABSTRACT

Salmonella is one of the main causes of human foodborne illness. It is endemic worldwide, with different animals and animal-based food products as reservoirs and vehicles of infection. Identifying animal reservoirs and potential transmission pathways of Salmonella is essential for prevention and control. There are many approaches for source attribution, each using different statistical models and data streams. Some aim to identify the animal reservoir, while others aim to determine the point at which exposure occurred. With the advance of whole-genome sequencing (WGS) technologies, new source attribution models will greatly benefit from the discriminating power gained with WGS. This review discusses some key source attribution methods and their mathematical and statistical tools. We also highlight recent studies utilizing WGS for source attribution and discuss open questions and challenges in developing new WGS methods. We aim to provide a better understanding of the current state of these methodologies with application to Salmonella and other foodborne pathogens that are common sources of illness in the poultry and human sectors.

ABSTRACT

BACKGROUND: There are conflicting data on the effect of cardiac resynchronization therapy with a defibrillator (CRT-D) on the risk of life-threatening ventricular tachyarrhythmia in heart failure patients.

OBJECTIVES: The authors aimed to assess whether QRS morphology is associated with risk of ventricular arrhythmias in CRT recipients.

METHODS: The study population comprised 2,862 patients implanted with implantable cardioverter defibrillator (ICD)/CRT-D for primary prevention who were enrolled in 5 landmark primary prevention ICD trials (MADIT-II [Multicenter Automated Defibrillator Implantation Trial], MADIT-CRT [Multicenter Automated Defibrillator Implantation Trial-Cardiac Resynchronization Therapy], MADIT-RIT [Multicenter Automated Defibrillator Implantation Trial-Reduction in Inappropriate Therapy], MADIT-RISK [Multicenter Automated Defibrillator Implantation Trial-RISK], and RAID [Ranolazine in High-Risk Patients With Implanted Cardioverter Defibrillators]). Patients with QRS duration ≥130 ms were divided into 2 groups: those implanted with an ICD only vs CRT-D. The primary endpoint was fast ventricular tachycardia (VT)/ventricular fibrillation (VF) (defined as VT ≥200 beats/min or VF), accounting for the competing risk of death. Secondary endpoints included appropriate shocks, any sustained VT or VF, and the burden of fast VT/VF, assessed in a recurrent event analysis.

RESULTS: Among patients with left bundle branch block (N = 1792), those with CRT-D (N = 1,112) experienced a significant 44% (P < 0.001) reduction in the risk of fast VT/VF compared with ICD-only patients (N = 680), a significantly lower burden of fast VT/VF (HR: 0.55; P = 0.001), with a reduced burden of appropriate shocks (HR: 0.44; P < 0.001). In contrast, among patients with non-left bundle branch block (NLBBB) (N = 1,070), CRT-D was not associated with reduction in fast VT/VF (HR: 1.33; P = 0.195). Furthermore, NLBBB patients with CRT-D experienced a statistically significant increase in the burden of fast VT/VF events compared with ICD-only patients (HR: 1.90; P = 0.013).

CONCLUSIONS: Our data suggest a potential proarrhythmic effect of CRT among patients with NLBBB. These data should be considered in patient selection for treatment with CRT.

ABSTRACT

BACKGROUND: Biological sex has a diverse impact on the cardiovascular system. Its influence on dilated cardiomyopathy (DCM) remains unresolved.

OBJECTIVES: This study aims to investigate sex-specific differences in DCM presentation, natural history, and prognostic factors.

METHODS: We conducted a prospective observational cohort study of DCM patients assessing baseline characteristics, cardiac magnetic resonance imaging, biomarkers, and genotype. The composite outcome was cardiovascular mortality or major heart failure (HF) events.

RESULTS: Overall, 206 females and 398 males with DCM were followed for a median of 3.9 years. At baseline, female patients had higher left ventricular ejection fraction, smaller left ventricular volumes, less prevalent mid-wall myocardial fibrosis (23% vs 42%), and lower high-sensitivity cardiac troponin I than males (all P < 0.05) with no difference in time from diagnosis, age at enrollment, N-terminal pro-B-type natriuretic peptide levels, pathogenic DCM genetic variants, myocardial fibrosis extent, or medications used for HF. Despite a more favorable profile, the risk of the primary outcome at 2 years was higher in females than males (8.6% vs 4.4%, adjusted HR: 3.14; 95% CI: 1.55-6.35; P = 0.001). Between 2 and 5 years, the effect of sex as a prognostic modifier attenuated. Age, mid-wall myocardial fibrosis, left ventricular ejection fraction, left atrial volume, N-terminal pro-B-type natriuretic peptide, high-sensitivity cardiac troponin I, left bundle branch block, and NYHA functional class were not sex-specific prognostic factors.

CONCLUSIONS: We identify a novel paradox in prognosis for females with DCM. Female DCM patients have a paradoxical early increase in major HF events despite less prevalent myocardial fibrosis and a milder phenotype at presentation. Future studies should interrogate the mechanistic basis for these sex differences.

ABSTRACT

PURPOSE: The aim of this project was to investigate whether opioid pain scores, postoperative opioid requirements, and postanesthesia care unit (PACU) length of stay were impacted when comparing a 24-hour intravenous lidocaine infusion versus postoperative discontinuation of the lidocaine infusion.

DESIGN: A retrospective chart review was used both before and after the discontinuation of postoperative lidocaine infusions for a quality improvement project.

METHODS: The project was carried out in the adult surgery PACU setting at a level 1 trauma center between April 2021 and September 2021. The sample included 100 adult patients who fell under surgical specialties that used enhanced recovery after surgery protocol. After approval was obtained, data was collected via an electronic chart review using an evaluation tool created by the project team.

FINDINGS: Between the five surgical specialties used for this review, the PACU length of stay variable was reduced only in the gynecology oncology service (P= .041). Additionally, the postoperative opioid requirements were significantly reduced in the surgical oncology service (P = .02). Comparing the groups as a whole, 50 participants who had a 24-hour continuous lidocaine infusion and 50 participants whose lidocaine infusion was discontinued before PACU admission had no statistically significant values with pain scores, postoperative opioid requirements, and PACU length of stay.

CONCLUSIONS: Results indicate that a 24-hour lidocaine infusion did not impact this patient population’s pain scores, postoperative opioid requirements, or PACU length of stay.
