Nicotine replacement therapy (NRT) is effective in increasing quit attempts and abstinence but is underused. We assessed the feasibility of mobile chat-based intervention combined NRT sampling (NRT-S) on abstinence. In this two-arm, single-blinded, randomized controlled trial, adult (≥18 years) daily cigarette smokers were proactively recruited from Hong Kong community settings using 'foot-in-the-door' approach during December 2017 to March 2018. All participants received brief advice on quitting, 1-week of NRT-S, active referral to smoking cessation services, and were individually randomized (11) at baseline. The intervention group received two months of chat-based support via instant messaging. The control group received general smoking cessation text messages. The primary outcome was smoking abstinence validated by exhaled carbon monoxide (<4 ppm) and salivary cotinine (<10 ng/mL) at 3 and 6 montion, quit attempts, and NRT-S use in proactively recruited community smokers.

The purpose of this report is to record noteworthy events that occurred during the early years of chiropractic in the United States Military Health System (MHS). We used mixed methods to create this historical account, including documents, artifacts, research papers, and reports from personal experiences. Chiropractic care was first included in the MHS in 1995, after years of legislative activity. The initial program was a 3-year study of the feasibility and advisability of integrating chiropractic in the MHS. This period was called the Chiropractic Health Care Demonstration Project; 20 pioneering chiropractors began their MHS journeys at 10 military bases in fiscal year 1995. The Demonstration Project was extended for 2 mo
