Long-Term Follow-up Study of Hospitalizations for Acute Coronary Syndrome in Kobe-City and Other Districts Under the Hyogo Smoking Ban Legislation - A Nationwide Database Study.

Background: Hyogo Prefecture has managed smoking ban legislation with partial restrictions in public places (Hyogo-L) since 2013. Previous studies have reported a significant decrease in admissions for acute coronary syndrome (ACS) in Kobe-city, but not in other districts of Hyogo Prefecture in the 2 years after Hyogo-L. The aim of the present study was to define the long-term effect of Hyogo-L.

Effectiveness of a smoking cessation educational program for Japanese nurses on subsequent changes of behavior in delivering smoking cessation counseling.

Introduction: Despite the effectiveness of smoking cessation counseling, participation of nurses in delivering smoking cessation advice has been far from satisfactory in practice. Training nurses is considered to be important for increasing self-efficacy and skills for routine delivery of smoking cessation counseling. The aim of the present study was to evaluate the effectiveness of a smoking cessation educational program for Japanese nurses on subsequent changes of their behavior in delivering smoking cessation counseling, three months later.

How Self-Efficacy toward, Perceived Importance of, and Beliefs about Smoking Cessation Support Impact-Related Behaviors in Japanese Nursing Professionals.

This study investigated the relationships among Japanese nursing professionals' percetions of the importance of smoking cessation support (SCS), attitude toward SCS, SCS self-efficacy, and SCS behaviors. An anonymous, self-administered questionnaire was administered to 613 nursing professionals (valid response rate: 89.9%) who participated in SCS workshops in Japan between May 2019 and February 2020.

[Secondhand smoke exposure in a car].

Objective: The Health Promotion Act was revised in 2018 and prohibits smoking inside taxis and buses. However, there is no regulation for smoking in the business vehicles of companies or private cars. This paper examined exposure to secondhand smoke in vehicles with digital dust monitors.

Exposure Assessment of Environmental Tobacco Aerosol from Heated Tobacco Products: Nicotine and PM Exposures under Two Limited Conditions.

It is too early to provide a clear answer on the impact of exposure to the second-hand aerosol of heated tobacco products (HTPs) in the planning of policy for smoke-free indoors legislation. Here, we conducted a preliminary study to evaluate indoor air quality with the use of HTPs. We first measured the concentration of nicotine and particulate matter (PM) in the air following 50 puffs in the use of HTPs or cigarettes in a small shower cubicle.

Estimating the Carcinogenic Potency of Second-Hand Smoke and Aerosol from Cigarettes and Heated Tobacco Products.

The revised Promotion Act, enforced in April 2020, allows the establishment of dedicated smoking rooms for heated tobacco products (HTPs). Since carcinogenicity assessment is unable to determine the safe level of secondhand smoke, we estimated excess lifetime cancer risk using previously reported risk factors. Assuming that nicotine inhalation is proportional to cancer potency, the lifetime cancer risk for HTP IQOS is expected to be below 10 (1/100,000), which is three orders of magnitude lower than that for cigarettes.

Characteristics of Abdominal Aortic Aneurysm in Japanese Patients Aged 50 Years or Younger.

We investigated the characteristics and surgical outcomes of abdominal aortic aneurysm (AAA), which typically occurs in elderly persons, in Japanese patients aged 50 years or younger. Clinical records of 999 patients who underwent open or endovascular repair for AAA at our hospital between 2007 and 2015 were reviewed to identify the clinical characteristics and surgical outcomes of young patients with AAA. The cohort included 14 patients aged 50 years or younger (mean, 40.

Electronic Cigarette Use and Smoking Abstinence in Japan: A Cross-Sectional Study of Quitting Methods.

The benefit of electronic cigarettes (e-cigarettes) in smoking cessation remains controversial. Recently, e-cigarettes have been gaining popularity in Japan, without evidence of efficacy on quitting cigarettes. We conducted an online survey to collect information on tobacco use, difficulties in smoking cessation, socio-demographic factors, and health-related factors in Japan.

Acute Aortic Dissection Occurring "Behind The Wheel", Report of 11 Cases.

We investigated the clinical picture of non-traumatic acute aortic dissection (AAD) occurring behind the wheel. Between 1990 and 2014, AAD had occurred in 11 patients while driving (nine men, mean age; 58.3 years, seven commercial drivers).

Biodegradation of chlordane and hexachlorobenzenes in river sediment.

Contamination of river sediments by persistent organic pollutants (POPs) is a worldwide concern, and microbial degradation is regarded as an important process for removal of POPs from river sediments. To date, there is still a lack of systematic study on chlordane biodegradation in river sediments, and the information on hexachlorobenzene (HCB) biodegradation in river sediments is very limited in Japan. We investigated the anaerobic biodegradation potential of trans-chlordane (TC), cis-chlordane (CC), and HCB in sediment samples collected at three sites along the Kamogawa River in Saitama Prefecture, Japan.

Epicardial radiofrequency ablation for chronic atrial fibrillation undergoing simultaneous on-pump beating coronary artery bypass grafting.

Off-pump coronary artery bypass grafting has become an attractive surgical alternative for myocardial revascularization because of the advantage of myocardial protection and other benefits of patients. However, it is still regarded as a controversial treatment for the coronary artery disease accompanied by atrial fibrillation (AF). A significant number of patients in need of coronary revascularization have chronic AF.
