Despite advances in obstetric care, postpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide. Prior reviews of studies published through 2016 suggest an association of antidepressant use during late pregnancy and increased risk of PPH. However, a causal link between prenatal antidepressants and PPH remains controversial.

Article Synopsis
  • The study aimed to explore the trends of depression and anxiety among individuals with rheumatoid arthritis (RA) over a 30-year period, comparing them to matched non-RA individuals.
  • Researchers analyzed data from 1012 patients with RA and matched controls, finding that anxiety and co-occurring anxiety and depression increased significantly from 2005-2014 compared to 1985-1994, particularly in seropositive RA patients.
  • The findings highlight a growing concern for mental health among RA patients, suggesting an increased need for clinicians to address these rising rates of anxiety and depression.

Pharmacogenomic (PGx) biomarkers integrated using machine learning can be embedded within the electronic health record (EHR) to provide clinicians with individualized predictions of drug treatment outcomes. Currently, however, drug alerts in the EHR are largely generic (not patient-specific) and contribute to increased clinician stress and burnout. Improving the usability of PGx alerts is an urgent need.

Article Synopsis
  • - The study aimed to determine if exome sequencing could help efficiently identify individuals with hereditary breast and ovarian cancer (HBOC) and Lynch syndrome (LS), which are genetic conditions linked to increased cancer risk.
  • - Over 44,000 participants were recruited across diverse regions in the U.S., resulting in the identification of 550 carriers of HBOC and LS, with 52.1% being newly diagnosed and 39.2% not meeting current genetic evaluation criteria.
  • - The findings suggest a need for broader use of germline genetic screening to improve the screening and detection of those predisposed to these cancer syndromes, particularly among underrepresented populations.

This nonrandomized, multicenter, open-label clinical trial explored the impact of intravenous (IV) ketamine on cognitive function in adults (n = 74) with treatment-resistant depression (TRD). Patients received three IV ketamine infusions during the acute phase and, if remitted, four additional infusions in the continuation phase (Mayo site). Cognitive assessments using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were conducted at baseline, end of the acute phase, and end of the continuation phase (Mayo site).

Background: When job demand exceeds job resources, burnout occurs. Burnout in healthcare workers extends beyond negatively affecting their functioning and physical and mental health; it also has been associated with poor medical outcomes for patients. Data-driven technology holds promise for the prediction of occupational burnout before it occurs.

Objective: To examine the associations between antidepressant exposure during the third trimester of pregnancy, including individual drugs, drug doses, and antidepressant combinations, and the risk of poor neonatal adaptation (PNA).

Patients And Methods: The Rochester Epidemiology Project medical records-linkage system was used to study infants exposed to selective serotonin reuptake inhibitors (SSRIs; n=1014), bupropion, (n=118), serotonin-norepinephrine reuptake inhibitors (n=80), antidepressant combinations (n=20), or other antidepressants (n=22) during the third trimester (April 11, 2000-December 31, 2013). Poor neonatal adaptation was defined based on a review of medical records.

Article Synopsis
  • Severe persistent mental illness (SPMI) negatively impacts cancer patients' outcomes, particularly after mastectomy for breast cancer.
  • In a study of 670 breast cancer patients, those with SPMI were more likely to undergo bilateral mastectomy and less likely to receive breast reconstruction compared to those without SPMI.
  • Patients with SPMI had longer hospital stays and a higher risk of post-surgical infections and sepsis, indicating a need for better screening and management strategies for these individuals.

Article Synopsis
  • - The effectiveness of antidepressants for major depressive disorder (MDD) varies greatly among individuals, highlighting the need for better prediction methods for treatment outcomes, complicated by numerous biological, psychological, and environmental factors.
  • - This report reviews various studies on the use of machine learning (ML) and pharmacogenomics to predict how patients with MDD respond to antidepressants, noting their results, limitations, and opportunities for future research.
  • - While ML techniques show potential in predicting short-term responses to antidepressants, they should complement clinical judgment and require collaboration among healthcare and tech professionals for effective implementation and education.

Article Synopsis
  • Many patients with major depressive disorder do not benefit significantly from antidepressant treatment, but there's no clear definition of what "no meaningful benefit" (NMB) means.
  • A study used equipercentile linking to determine that a 30% improvement in the 17-item Hamilton Depression Rating Scale (HDRS-17) score correlates with a Clinical Global Impressions-Improvement (CGI-I) score of 3, indicating minimal improvement, after 4 and 8 weeks of treatment with citalopram or escitalopram.
  • The findings suggest that a maximum improvement of 30% in depression severity ratings can reliably indicate NMB from antidepressants for patients during short-term treatment periods.

This article provides an updated review of the pharmacological profile and available efficacy and tolerability/safety data for vilazodone, one of the most recent antidepressant drugs to be approved in the USA for the treatment of major depressive disorder (MDD) in adults. The efficacy of vilazodone for MDD in adults is supported by four positive short-term (8-10 weeks), randomized, placebo-controlled trials. Beyond these pivotal trials, we review updated research findings pertaining to the clinical effects of vilazodone for MDD including the results of switch studies, small comparative efficacy trials, key pooled and secondary data analyses focused on important depressive subtypes (anxious depression) and predictors of treatment outcome, and safety studies including direct studies of sexual side-effects.

The Clinical Global Impressions-Improvement (CGI-I) scale is widely used in clinical research to assess symptoms and functioning in the context of treatment. The correlates of the CGI-I with efficacy scales for adolescent major depressive disorder are poorly understood. This study focused on benchmarking CGI-I scores with changes in the Children's Depression Rating Scale-Revised (CDRS-R) and the Quick Inventory of Depressive Symptomatology-Adolescent (17-item) Self-Report (QIDS-A17-SR).

Importance: Longitudinal associations between comorbid depression and anxiety with the accumulation of chronic illnesses are unclear, and questions remain about the contributions associated with each condition in the increasing prevalence of multimorbidity.

Objective: To compare the risk and rate of accumulating chronic conditions in people with depression, anxiety, and comorbid depression and anxiety vs individuals with neither depression nor anxiety.

Design, Setting, And Participants: This cohort study used the Rochester Epidemiology Project medical records-linkage system to identify residents of Olmsted County, Minnesota, from January 1, 2005, to December 31, 2014, with follow-up ending December 31, 2017.

Age at depressive onset (AAO) corresponds to unique symptomatology and clinical outcomes. Integration of genome-wide association study (GWAS) results with additional “omic” measures to evaluate AAO has not been reported and may reveal novel markers of susceptibility and/or resistance to major depressive disorder (MDD). To address this gap, we integrated genomics with metabolomics using data-driven network analysis to characterize and differentiate MDD based on AAO.
