Summary: Smoking prevalence is high among patients with serious mental illness. Digital interventions for smoking cessation have shown promise in non-clinical populations, but their effectiveness in patients with serious mental illness is uncertain. This systematic review evaluated the effectiveness, acceptability, adherence, usability, and safety of digital interventions for smoking cessation in patients with serious mental illness. Thirteen articles were included, reporting data on nine different digital interventions. Overall, digitally delivered health interventions for smoking cessation show promise, but larger trials with standardized measures are needed to provide more definitive evidence and recommendations.

Summary: This study investigated whether comorbid substance use disorders (SUDs) in bipolar disorder (BD) were associated with differences in medication regimens. The results showed that overall, BD with comorbid SUD did not have different pharmacological treatment compared to BD alone. However, there were country-specific associations between specific SUDs and medications, indicating the need for further research.

Summary: The use of structured interviews helped physicians identify major depressive disorder by the second visit in patients with complex psychopathology. Patients with high complexity/severity of symptoms and more difficulty with functioning were less commonly identified with bipolar disorder even with the assistance of a structured interview.Structured assessment tools may improve the detection of psychiatric illness by clinicians at the first visit.

Summary: This study aimed to assess the association and familial coaggregation between early-onset type 2 diabetes and mood, anxiety, and stress-related disorders and estimate the contribution of genetic and environmental factors to their co-occurrence. The findings suggest that there is a higher risk of psychiatric disorders among individuals with early-onset type 2 diabetes and their relatives, and this association is largely explained by genetic factors.

Summary: The prevalence, correlates, and management of tobacco use disorder (TUD) or nicotine dependence (ND) among people with severe mental illness (SMI) remain unclear. Rates of TUD/ND co-occurrence are high, especially among males, and while bupropion and varenicline show promise for treating schizophrenia patients with TUD/ND, non-pharmacological interventions require further research, especially for those with primary mood disorders. More well-designed RCTs are needed to inform the management of TUD/ND among people with SMI.

Summary: Evidence suggests a higher comorbidity rate of obsessive-compulsive disorder (OCD) in bipolar disorder (BD) patients, particularly in those experiencing bipolar depression (BP-D). A study found 26% of BD patients with their first depressive episode also had OCD, while 23.2% met criteria for subthreshold OCD. No differences in demographic and clinical variables were observed between BD patients with and without OCD. Further research is needed to explore the longitudinal course, treatment approaches, and outcomes of comorbid BP-D/OCD.

Summary: Major depressive disorder is a common and heterogeneous illness, with treatment resistance observed in at least 50% of patients. Initial research focused on the monoamine system, but recent studies have explored other mechanisms, including synaptic involvement in depression. This article discusses reductions in synaptic density, dendritic spines, boutons, and glia associated with stress and depression, as well as the potential of drugs like ketamine to restore or generate synapses. Neuroimaging techniques, such as MRI and PET, are valuable tools for assessing these synaptic changes in vivo and monitoring synaptic restoration after ketamine administration. While more research is needed, these techniques enhance our understanding of depression and contribute to the development of targeted and effective treatments.

Summary: Clinical investigations have shown that metabotropic glutamate receptor 5 (mGluR5) is involved in the pathophysiology of fear learning in trauma-related disorders. This study used a 4-day fear learning paradigm combined with positron emission tomography (PET) to examine the relationship between mGluR5 availability and the response of rats to repeated footshock exposure. The results suggest that increased mGluR5 availability following footshock exposure may be related to greater contextual fear memory, and there are sex differences in the molecular response to footshock, including differential involvement of mGluR5-related molecular networks.

Summary: This study measured the availability of metabotropic glutamate receptor 5 (mGluR5) in individuals with bipolar disorder (BD) and major depressive disorder (MDD) using positron emission tomography. The results showed significant differences in mGluR5 availability between BD, MDD, and healthy control groups, suggesting a potential role of mGluR5 as a treatment target for depressive symptoms in MDD and cognitive alterations in both disorders.

Summary: PF-05212377 is a potent and selective 5-HT6 antagonist that was previously developed for Alzheimer's disease treatment. Species differences were observed in its brain penetration, with a higher ratio in non-human primates compared to rats. Pre-clinical and clinical evidence confirmed the similarity of PF-05212377's brain penetration and target engagement between non-human primates and humans, suggesting that non-human primates are more suitable for predicting human brain penetration for this drug.

Summary: This study aimed to investigate the associations between resting-state network (RSN) connectivity and synaptic density. The findings showed that higher synaptic density in the medial prefrontal cortex was associated with greater fractional amplitude of low-frequency fluctuations (fALFF) in the anterior default-mode, posterior default-mode, and executive-control networks. Additionally, higher synaptic density in the striatum was associated with greater fALFF in the anterior default-mode and salience networks. These results provide initial evidence of a neurophysiological link between RSN activity and local synaptic density, which may be relevant in neurodegenerative and psychiatric disorders.

Summary: Alterations in glutamatergic and GABAergic function in the medial prefrontal cortex (mPFC) play a role in major depressive disorder. Scopolamine, a muscarinic receptor antagonist, has rapid antidepressant-like effects by targeting M1-type acetylcholine receptors (M1R). In this study, M1R deletion in SST interneurons in the mPFC attenuates the antidepressant-like effects of scopolamine and impairs GABAergic and glutamatergic function. These findings suggest that modulation of excitatory and inhibitory plasticity via M1R blockade in SST interneurons could be a promising strategy for developing antidepressants.

Summary: The neurotransmitter acetylcholine (ACh) plays a crucial role in regulating various cognitive and behavioral processes. Measurement of ACh dynamics in the brain is essential for understanding the neural mechanisms underlying these processes. This review discusses several techniques for measuring ACh levels in the brain in vivo, with a focus on genetically encoded fluorescent sensors coupled with fiber photometry. These sensors provide a means for accurately measuring ACh release in awake, behaving animals, contributing to a better understanding of cholinergic modulation of complex behaviors.
