Longitudinal Description and Prediction of Smoking Among Borderline Patients: An 18-Year Follow-Up Study.

Objective: The objectives of this study were (1) to compare smoking between recovered and non-recovered patients with borderline personality disorder (BPD) over the course of 18 years and (2) to assess baseline predictors of tobacco use in patients with BPD.Methods: A total of 264 borderline patients were interviewed concerning their smoking history beginning at the 6-year follow-up wave in a longitudinal study of the course of BPD (McLean Study of Adult Development) and re-interviewed at 2-year intervals over the next 18 years. Initial data collection of the larger study happened between June 1992 and December 1995, and the DSM-III-R and the Revised Diagnostic Interview for Borderlines (DIB-R) were used as the diagnostic instruments for BPD.Results: Recovered patients had a 48% lower prevalence of smoking than non-recovered patients at 6-year follow-up (a significant difference; P = .01). Also, the rate of decline in smoking for the recovered group was 68% and was significantly faster (P = .008) than for the non-recovered group over the subsequent 18 years. Alcohol abuse or dependence (relative risk [RR] = 1.22; 95% CI, 1.06-1.40; P = .005), lower levels of education (RR = 1.28; 95% CI, 1.15-1.42; P < .001), and higher levels of the defense mechanism of denial (RR = 1.08; 95% CI, 1.03-1.13; P = .002) were significant predictors of smoking in borderline patients in multivariate analyses.Conclusions: Taken together, the results of this study suggest that recovery status was an important element in the prevalence of smoking among borderline patients over time. They also suggest that smoking was predicted by 3 factors: prior psychopathology, demographics, and psychological maturity.

Neuroimaging Studies of Nonsuicidal Self-Injury in Youth: A Systematic Review.

Nonsuicidal self-injury (NSSI) is prevalent and affects mainly the youth population. It is prospectively associated with suicide attempts, making it a target for suicide prevention. Recently, several studies have investigated neural pathways of NSSI using neuroimaging. However, there is a lack of systematized appraisal of these findings. This systematic review aims to identify and summarize the main neuroimaging findings of NSSI in youth. We followed PRISMA statement guidelines and searched MEDLINE, APA PsycInfo, and Google Scholar databases for neuroimaging studies, irrespective of imaging modality, specifically investigating NSSI in samples with a mean age of up to 25 years old. Quality assessment was made using the Newcastle-Ottawa and Joanna Briggs Institute scales. The initial search retrieved 3030 articles; 21 met inclusion criteria, with a total of 938 subjects. Eighteen studies employed functional neuroimaging techniques such as resting-state and task-based fMRI (emotional, interpersonal exposure/social exclusion, pain, reward, and cognitive processing paradigms). Three studies reported on structural MRI. An association of NSSI behavior and altered emotional processing in cortico-limbic neurocircuitry was commonly reported. Additionally, alterations in potential circuits involving pain, reward, interpersonal, self-processing, and executive function control processes were identified. NSSI has complex and diverse neural underpinnings. Future longitudinal studies are needed to understand its developmental aspects better.
