Depressive symptoms are common in the growing geriatric surgical population and are associated with important patient-centred surgical outcomes, including postoperative delirium, discharge to postacute care facility and decline in functional status. Few interventions have been developed to address depressive symptoms in the perioperative setting.

We designed a feasibility and acceptability study of a nine-session problem-solving therapy (PST) telehealth perioperative intervention aimed at reducing postoperative functional decline and depressive symptoms among at-risk older adults undergoing major surgical procedures. Acceptability will be evaluated using a patient-centred five-question survey, assessing participant satisfaction and perceived usefulness of the perioperative intervention. A feasibility assessment will rely on objective measures including ease of participant recruitment, frequency and timing of delivery of intervention sessions and retention of participants throughout the duration of the intervention. With respect to the efficacy of the proposed PST intervention, the primary outcome of interest is postoperative functional status, as measured by the WHO Disability Assessment Schedule 2.0 at the 6-month postoperative time point. The secondary outcome of interest is the degree of depressive symptoms as assessed by the Patient Health Questionnaire-9 at both 3 months and 6 months postoperatively. The broader goals of this study include: (1) assessing the feasibility of implementing a PST perioperative intervention for older surgical patients at risk of postoperative functional decline, (2) demonstrating the acceptability of the PST intervention and (3) assessing the preliminary impact of the PST intervention on postoperative functional status and depressive symptoms.

The study received ethical approval from the University of California San Francisco Institutional Review Board. Results of this study will be published in peer-reviewed scientific journals with further dissemination at local institutional meetings and professional conferences.

This study aims to estimate the prevalence and dual use of cigarettes, heated tobacco products (HTPs) and electronic cigarettes (e-cigarettes) among individuals aged 18–24 in Japan.

This cross-sectional study involved a door-to-door survey administered by trained interviewers using a structured questionnaire.

Individuals aged 18–24 residing in 220 areas within 10 ordinance-designated cities (Sapporo, Sendai, Saitama, Chiba, Yokohama, Kawasaki, Sagamihara, Nagoya, Osaka and Fukuoka) as well as Tokyo’s 23 wards in Japan in 2019 were included.

A total of 1738/5500 individuals were included in the analysis, with participants evenly distributed by sex, age and residential area.

Cigarette, HTP and e-cigarette use was assessed.

The weighted prevalence of the current use of cigarettes, HTPs and e-cigarettes accounted for 10.1% (95% CI 8.7, 11.5), 5.1% (95% CI 4.1, 6.1) and 1.8% (95% CI 1.2, 2.4), respectively. Approximately 68.2% of the people who used HTPs at the time were dual users of both HTPs and cigarettes. There was a significant gap in tobacco product use between individuals aged 20–24 and those aged 18–19, with this difference remaining after adjusting for covariates.

In 2019, cigarettes were the most used tobacco-related product among young adults in Japan. Smoking initiation appears to notably increase at age 20 when smoking becomes legal in Japan. The prevalence of HTP use among young adults in Japan is notably higher than in other countries.
