Previous research has identified a replicable role for the posterior parietal cortex (PPC) in risk behaviors, but it is unclear whether this relationship is causal. Here, we used a targeted neuromodulation protocol leveraging a single-session of 10-Hz rTMS to the PPC versus a control region in the visual cortex (V5), as well as two active comparison regions [superior frontal gyrus (SFG), dorsolateral prefrontal cortex (DLPFC)] (within-person, randomized order), to examine within-session changes in a comprehensive measure of self-reported risk-taking propensity (the Domain-Specific Risk-Taking or DOSPERT scale). Individuals with tobacco use disorder were selected as sample participants who present with clinically relevant risk-taking propensity ( = 50; 14 women, mean [] age=33.

We report a case of a new-onset, persistent tremor that developed during a clinical trial (NCT02927236) of intermittent theta burst stimulation [iTBS, a form of repetitive magnetic transcranial magnetic stimulation (rTMS)] for cocaine use disorder. Although the participant exhibited an exceptionally strong clinical response, subsequent unblinding revealed that they received sham iTBS. This case highlights the potential for strong functional neurological placebo responses in rTMS trials, and functional disorders might be a marker of a placebo response.

Background: Auditory verbal hallucinations (AVH) are a disabling symptom for people with schizophrenia (SCZ), and do not always respond to antipsychotics. Repetitive transcranial magnetic stimulation (rTMS) has shown efficacy for medication-refractory AVH, though the underlying neural mechanisms by which rTMS produces these effects remain unclear. This systematic review evaluated the structural and functional impact of rTMS for AVH in SCZ, and its association with clinical outcomes.

Article Synopsis
  • The study reviews the last 25 years of functional magnetic resonance imaging drug cue reactivity (FDCR) research, highlighting the gap between findings and clinical applications as no FDCR-derived biomarkers have been approved yet.
  • The objective is to summarize FDCR research, evaluate its readiness for biomarker development, and propose a systematic process for qualifying these biomarkers in the context of addiction treatment.
  • Out of 415 published FDCR studies from 1998 to 2022, a significant number explored addictive substances like nicotine and alcohol, suggesting potential for developing various types of biomarkers related to addiction, though most studies mainly focused on therapeutic and diagnostic responses.

While pharmacological, behavioral and psychosocial treatments are available for substance use disorders (SUDs), they are not always effective or well-tolerated. Neuromodulation (NM) methods, including repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS) and deep brain stimulation (DBS) may address SUDs by targeting addiction neurocircuitry. We evaluated the efficacy of NM to improve behavioral outcomes in SUDs.

Background: Metabolic and bariatric surgery (MBS) is the most effective and durable obesity treatment. However, there is heterogeneity in weight outcomes, which is partially attributed to variability in appetite and eating regulation. Patients with a strong desire to eat in response to the reward of palatable foods are more likely to overeat and experience suboptimal outcomes.

Background: After a Design Team (DT) conducted a workforce health assessment of correctional supervisors, they selected sleep as an intervention priority, given its numerous health and work consequences. Existing workplace sleep interventions are designed with little worker input, but participatory solutions that incorporate workers' lived experiences and root causes of poor sleep may be more relevant, appropriate, and acceptable to end-users, resulting in better uptake.

Methods: The DT met bi-monthly to complete the Intervention Design and Analysis Scorecard (IDEAS) tool to brainstorm interventions that address root causes of poor sleep, and evaluate, rank, and select interventions for implementation.

Background: Substance use disorders (SUDs) are a common yet poorly studied comorbidity in individuals with psychotic disorders. The co-occurrence of the two complicates recovery and interferes with pharmacological and behavioral treatment response and adherence. Recently, researchers have been exploring both invasive and non-invasive neuromodulation techniques as potential treatment methods for SUDs.

Introduction: The global burden of maternal mortality remains high and inequitably distributed between countries. Antenatal care (ANC) was identified as critical component in achieving the Millennium Development Goal of improving maternal health. This scoping review aimed to summarize trends and critically explore research about ANC attendance for East African women conducted during the Millennium Development Goals initiative, with a specific focus on barriers to ANC access.

Background: Indigenous women world-wide are diverse and heterogenous, yet many have similar experiences of colonization, land dispossession, and discrimination. These experiences along with inequitable access to, and quality of, maternal healthcare increase adverse maternal health outcomes. To improve health outcomes for Indigenous women, studies must be conducted with Indigenous involvement and reflect Indigenous research principles.

Recent research has demonstrated that psychopathic offenders exhibit dynamic cognitive and behavioral deficits on a variety of lab tasks that differentially activate left hemisphere resources. The Left Hemisphere Activation (LHA) hypothesis is a cognitive perspective that aims to address these deficits by conceptualizing psychopathy as a disorder in which behavior and cognitive processing change dynamically as a function of the differential taxation of left hemisphere resources. This study aimed to investigate whether psychopathic traits are associated with electrophysiological anomalies under conditions that place differential demands on left hemisphere language processing systems.

Developing new, effective treatments for substance use disorders (SUDs), especially cocaine and opioid use disorders (CUD and OUD), are of immense importance. These are chronic, relapsing brain diseases characterized by dysregulated circuits manifesting from neuroplastic change brought on by repeated exposure to substances of abuse. A potential treatment is therapeutically inducing neuroplastic change in targeted dysregulated circuits.

Introduction: The correctional workforce experiences persistent health problems, and interventions designed with worker participation show favorable outcomes. However, participatory intervention research often leaves workers out of the health needs assessment, the basis of interventions subsequently developed. This omission risks failure to detect factors contributing to the health and is less likely to result in primary prevention interventions.
