Background: Selective Serotonin Reuptake Inhibitors (SSRIs) represent a diverse class of medications widely prescribed for depression and anxiety. Despite their common use, there is an absence of large-scale, real-world evidence capturing the heterogeneity in their effects on individuals. This study addresses this gap by utilizing naturalistic search data to explore the varied impact of six different SSRIs on user behavior.

Objective: To test whether the association between flavor at first vape and continued use is mediated through subjective experience at first vape.

Study Design: In a 2020 cross-sectional survey, 955 young adult ever-vapers recalled their first flavor vaped, subjective experiences at first use, current vaping behavior, nicotine dependence, and quit attempts. A latent class model grouped first-use subjective experiences into classes.

Early-life adversity increases the risk of health problems. Interventions supporting protective and responsive caregiving offer a promising approach to attenuating adversity-induced changes in stress-sensitive biomarkers. This study tested whether participation in an evidence-based dyadic psychosocial intervention, child-parent psychotherapy (CPP), was related to lower epigenetic age acceleration, a trauma-sensitive biomarker of accelerated biological aging that is associated with later health impairment, in a sample of children with trauma histories.

Importance: Posttraumatic stress disorder (PTSD) symptom reduction is linked with lower risk of incident type 2 diabetes (T2D), but little is known about the association between PTSD and comorbid T2D outcomes. Whether PTSD is a modifiable risk factor for adverse T2D outcomes is unknown.

Objective: To determine whether patients with PTSD who improved and no longer met diagnostic criteria for PTSD had a lower risk of adverse T2D outcomes compared with patients with persistent PTSD.

Passive smartphone measures hold significant potential and are increasingly employed in psychological and biomedical research to capture an individual's behavior. These measures involve the near-continuous and unobtrusive collection of data from smartphones without requiring active input from participants. For example, GPS sensors are used to determine the (social) context of a person, and accelerometers to measure movement.

Article Synopsis
  • The DSM's criteria for mental disorders allow for varied symptoms among individuals, but this has led to concerns about the reliability of these classifications in research due to inconsistent symptom combinations.
  • The study investigates how symptom definitions and assessments influence the likelihood of specific symptom combinations in disorders like PTSD, depression, schizophrenia, and anxiety.
  • Analyzing data from over 155,000 participants revealed that while some symptom combinations were more common, most had low probabilities of occurrence, indicating a skewed distribution in the way symptoms manifest across different individuals.

Background: Despite the frequent diagnostic delays of rare neurologic diseases (RND), it remains difficult to study RNDs and their comorbidities due to their rarity and hence the statistical underpowering. Affecting one to two in a million annually, stiff person syndrome (SPS) is an RND characterized by painful muscle spasms and rigidity. Leveraging underutilized electronic health records (EHR), this study showcased a machine-learning-based framework to identify clinical features that optimally characterize the diagnosis of SPS.

Posttraumatic stress disorder (PTSD) is associated with poor quality of life. Although randomized clinical trial data show improvements in quality of life following trauma-focused therapies (TFTs), including prolonged exposure therapy (PE) and cognitive processing therapy (CPT), less is known about how these improvements are experienced from the trauma survivor's perspective. A national sample of 60 veterans who recently completed TFT as part of routine care at U.

Article Synopsis
  • The review examines the connection between gastrointestinal (GI) conditions and sleep disturbances, noting a high prevalence of sleep issues among individuals with GI problems.
  • It highlights the role of arousal as a key factor in both insomnia and GI conditions, emphasizing the need to explore shared influences across various domains like psychosocial and physical health.
  • By analyzing this bidirectional relationship, the review advocates for a multidisciplinary approach to treatment that addresses both sleep and GI issues together.

Anhedonia and depressed mood are two cardinal symptoms of major depressive disorder (MDD). Prior work has demonstrated that cannabis consumers often endorse anhedonia and depressed mood, which may contribute to greater cannabis use (CU) over time. However, it is unclear (1) how the unique influence of anhedonia and depressed mood affect CU and (2) how these symptoms predict CU over more proximal periods of time, including the next day or week (rather than proceeding weeks or months).

Tics are a common feature of early-onset neurodevelopmental disorders, characterized by involuntary and repetitive movements or sounds. Despite affecting up to 2% of children and having a genetic contribution, the underlying causes remain poorly understood. In this study, we leverage dense phenotype information to identify features (i.

Article Synopsis
  • - The study investigates the effects of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies on health-related quality of life (HRQoL) and well-being among people with cystic fibrosis (PwCF) and their caregivers.
  • - Results show that adult PwCF currently on modulator therapy experience better physical and mental health compared to those who have stopped or never used the treatments, but some (23%) report declines in mental well-being.
  • - The findings aim to inform future research, policy, and communication efforts that could enhance the well-being of PwCF by understanding their experiences with modulator therapies.

  • Many-analyst studies investigate how well different analysis teams can interpret the same dataset and how robust their conclusions are against alternative methods.
  • Typically, these studies only report one outcome measure, like effect size, making it hard to grasp the full impact of different analysis choices.
  • To address this, researchers created the Subjective Evidence Evaluation Survey (SEES) using feedback from experts, helping to evaluate the quality of research design and evidence strength, ultimately offering a deeper understanding of analysis outcomes.

Background: Rural healthcare has unique characteristics that affect the dissemination and implementation of evidence-based interventions. Numerous theories, models, and frameworks have been developed to guide implementation of healthcare interventions, though not specific to rural healthcare. The present scoping review sought to identify the theories, models, and frameworks most frequently applied to rural health and propose an approach to rural health research that harnesses selected constructs from these theories, models, and frameworks.

Background: Depression is common in Parkinson's disease (PD) but is underrecognized clinically. Although systematic screening is a recommended strategy to improve depression recognition in primary care practice, it has not been widely used in PD care.

Methods: The 15-item Geriatric Depression Scale (GDS-15) was implemented at 5 movement disorders clinics to screen PD patients.

Article Synopsis
  • Major depressive disorder (MDD) and borderline personality disorder (BPD) frequently co-occur, with 20% of MDD patients meeting criteria for BPD, prompting a study on how BPD traits might affect the instability of depression symptoms over time.
  • The study involved 207 adults with MDD who tracked their depression symptoms three times a day for 90 days, measuring both BPD severity and neuroticism through self-report assessments.
  • Results showed that BPD severity did not significantly predict changes in depression symptoms, suggesting a complex relationship between these disorders and highlighting the need for further research on their association.
