Tabaquismo y trastorno mental grave: conceptualización, abordaje teórico y estudios de intervención.

El hábito tabáquico es un grave problema de salud en los pacientes con trastorno mental grave. Este trabajo realiza una revisión actualizada de sus bases neurofisiológicas y abordaje terapéutico. Existe una vinculación conocida entre neurotransmisión nicotínica y esquizofrenia sin una propuesta de modelo etiológico. El abordaje terapéutico del tabaquismo en enfermos psiquiátricos requiere formación específica y unidades de tabaquismo o servicios de salud mental preparados. La asociación con consumo de sustancias tóxicas, psicofármacos, comorbilidad psiquiátrica y falta de motivación profesional constituyen factores limitantes. La intervención breve aprovecha el contacto sanitario para explorar la presencia de tabaquismo y valorar la predisposición del paciente a dejar de fumar. El tratamiento utiliza terapia sustitutiva con nicotina, antidepresivos, agonistas del receptor nicotínico y/o intervenciones psicosociales. El tratamiento con bupropion es el más efectivo y seguro, mientras la terapia sustitutiva con nicotina y la vareniclina son también útiles. En la práctica clínica la utilización de farmacoterapia y psicoterapia puede ser la opción más razonable

Influence of social cognition as a mediator between cognitive reserve and psychosocial functioning in patients with first episode psychosis

Background: Social cognition has been associated with functional outcome in patients with first episode psychosis (FEP). Social cognition has also been associated with neurocognition and cognitive reserve. Although cognitive reserve, neurocognitive functioning, social cognition, and functional outcome are related, the direction of their associations is not clear. Therefore, the main aim of this study was to analyze the influence of social cognition as a mediator between cognitive reserve and cognitive domains on functioning in FEP both at baseline and at 2 years. Methods: The sample of the study was composed of 282 FEP patients followed up for 2 years. To analyze whether social cognition mediates the influence of cognitive reserve and cognitive domains on functioning, a path analysis was performed. The statistical significance of any mediation effects was evaluated by bootstrap analysis. Results: At baseline, as neither cognitive reserve nor the cognitive domains studied were related to functioning, the conditions for mediation were not satisfied. Nevertheless, at 2 years of follow-up, social cognition acted as a mediator between cognitive reserve and functioning. Likewise, social cognition was a mediator between verbal memory and functional outcome. The results of the bootstrap analysis confirmed these significant mediations (95% bootstrapped CI (-10.215 to -0.337) and (-4.731 to -0.605) respectively). Conclusions: Cognitive reserve and neurocognition are related to functioning, and social cognition mediates in this relationship

Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
