The prevalence, correlates, and management of tobacco use disorder (TUD) or nicotine dependence (ND) among people with severe mental illness (SMI), namely schizophrenia, bipolar disorder (BD), and major depressive disorder (MDD), remain unclear. Therefore, a systematic review and meta-analysis was conducted. Electronic databases were systematically searched from inception to July 12, 2020, for observational studies documenting the prevalence, odds, and correlates of TUD/ND among people with SMI; randomized controlled trials (RCTs) informing the management of TUD/ND in people with SMI were also included. Random-effects meta-analyses were conducted. Sources of heterogeneity were explored. Nineteen observational studies, including 7527 participants with SMI met inclusion criteria. TUD/ND co-occurred in 33.4-65% of people with SMI. Rates were higher among males. While bupropion and varenicline represent promising treatment opportunities for schizophrenia with TUD/ND, non-pharmacological interventions require further research, mainly for people with primary mood disorders. TUD/ND represent prevalent co-occurring conditions among people with SMI. Further well-designed RCTs are warranted to inform their management.

Despite the prevalence of these conditions, the interrelationships among them remain poorly understood in HD patients.

Methods: In this multicenter cross-sectional study, 858 HD patients from 7 dialysis centers were recruited.

Skeletal muscle index (SMI), as an effective indicator of nutritional status, plays an important role in the prognosis of malignancy. However, the impact of skeletal muscle changes on tumor prognosis has not been systematically elaborated. We aimed to explore the value of skeletal muscle changes in the prognosis of distal cholangiocarcinoma (DCC) patients undergone pancreaticoduodenectomy (PD).

The COVID-19 pandemic was an unprecedented global health crisis. Vulnerable populations with preexisting mental illness have been disproportionately burdened and may experience adverse mental health outcomes related to the COVID-19 pandemic. Our objective was to evaluate the association between COVID-19 diagnosis, known exposure to COVID-19, sheltering in place, symptom severity, psychological distress, and depression severity among adults with severe mental illness (SMI).

Objective: Tobacco smoking is the leading cause of preventable death among individuals with serious mental illness (SMI) but few persons with SMI are offered smoking cessation treatment. The purpose of this study was to pilot-test a multicomponent intervention to increase the delivery of evidence-based smoking cessation treatment in community mental health clinics (CMHCs).

Method: This study was carried out at five CMHCs in Maryland involving clinicians who participated in training in smoking cessation.

Aim: Identify values that could predict the presence of increased pressure-pain sensitivity independent of the migraine cycle through a single assessment.

Methods: This was a secondary analysis of a previous study in which 198 episodic and chronic migraine patients were assessed during all phases of the migraine cycle. Pressure pain threshold (PPT) was assessed over the temporalis, cervical spine, hand, and leg.
