There is a paucity of interventions for young adults who have parents with a mental health or substance use issue. The 6-week mi.spot (supportive, preventive, online, and targeted) professionally moderated, online intervention fills this gap. The purpose of this study was to present evidence of the acceptability, safety, and preliminary effectiveness of this intervention. In response to social media advertising, 31 young people aged 18–25 years participated in mi.spot. Intervention effectiveness was examined via a single-group pre, post, and 6-week follow-up study design, measuring primary changes in depression, anxiety, stress, and psychological well-being and secondary changes in coping, self-efficacy, social connectedness, attribution of responsibility, help-seeking, and mental health literacy. Acceptability and safety were determined by system use and participants' self-reports. Over the 6 weeks of the intervention, 28 (90.3%) of 31 participants used one or more components of the mi.spot intervention. Significant improvements were reported in depression and stress from preintervention to 6-week postintervention. Trend improvements were evident in well-being, social connection, and coping. No change was reported in general help-seeking, social connectedness, mental health literacy, self-efficacy, or attribution. No safety violations were reported. Participants reported mi.spot to be safe and acceptable. mi.spot appears to be safe and acceptable and shows promise as an effective online intervention to improve the mental health and well-being of young adults with parents with mental health and/or substance use issues.

Background & Aims The immunosuppressant rapamycin frequently causes noninfectious diarrhea in organ transplant recipients. We investigated the mechanisms of this process. Methods We performed a retrospective analysis of renal transplant recipients treated with rapamycin from 2003 through 2010 at Albany Medical College, collecting data on serum levels of rapamycin. Levels of the Na+/H+ exchanger 3 (NHE3) were measured in human ileal biopsy specimens from patients who did and did not receive rapamycin (controls), in ileum tissues from rats or mice given rapamycin, and in mice with intestine-specific disruption of mammalian target of rapamycin ( Mtor ) ( mTOR f/f :Villin-cre mice) or Atg7 ( Atg7 flox/flox ; Villin-Cre ). Exchange activity and intestinal water absorption were measured using a pH-sensitive dye and small intestine perfusion, respectively. Results Episodes of noninfectious diarrhea occurred in organ recipients after increases in serum levels of rapamycin. The expression of NHE3 was reduced in the ileal brush border of patients with diarrhea. In rats and mice, continuous administration of low doses of rapamycin reduced levels of NHE3 in intestinal tissues; this effect was not observed in mice with intestinal deletion of ATG7, indicating that autophagy is required for the reduction. Administration of single high doses of rapamycin to mice, to model the spikes in rapamycin levels that occur in patients with severe diarrheal episodes, resulted in reduced phosphorylation of S6 and AKT in ileal tissues, indicating inhibition of the mTOR complex (mTORC1 and mTORC2). The intestines of mice with intestine-specific deletion of mTOR were dilated and contained large amounts of liquid stools; they also had reduced levels of total NHE3 and NHERF1 compared with control mice. We observed a significant reduction in Na + /H + exchange activity in ileum tissues from these mice. Conclusions Rapamycin inhibition of mTOR reduces levels of NHE3 and Na + /H + exchange activity in intestinal tissues of patients and rodents. This process appears to require the autophagic activity mediated by ATG7. Loss of mTOR regulation of NHE3 could mediate the development of diarrhea in patients undergoing rapamycin therapy.
