Abstract
BACKGROUND: Currently, there are over 400 smoking cessation smartphone apps available, downloaded an estimated 780,000 times per month. No prior studies have examined how individuals engage with specific features of cessation apps and whether use of these features is associated with quitting. OBJECTIVES: Using data from a pilot trial of a novel smoking cessation app, we examined: (i) the 10 most-used app features, and (ii) prospective associations between feature usage and quitting. METHODS: Participants (n = 76) were from the experimental arm of a randomized, controlled pilot trial of an app for smoking cessation called "SmartQuit," which includes elements of both Acceptance and Commitment Therapy (ACT) and traditional cognitive behavioral therapy (CBT). Utilization data were automatically tracked during the 8-week treatment phase. Thirty-day point prevalence smoking abstinence was assessed at 60-day follow-up. RESULTS: The most-used features - quit plan, tracking, progress, and sharing - were mostly CBT. Only two of the 10 most-used features were prospectively associated with quitting: viewing the quit plan (p = 0.03) and tracking practice of letting urges pass (p = 0.03). Tracking ACT skill practice was used by fewer participants (n = 43) but was associated with cessation (p = 0.01). CONCLUSIONS: In this exploratory analysis without control for multiple comparisons, viewing a quit plan (CBT) as well as tracking practice of letting urges pass (ACT) were both appealing to app users and associated with successful quitting. Aside from these features, there was little overlap between a feature's popularity and its prospective association with quitting. Tests of causal associations between feature usage and smoking cessation are now needed.

Abstract
Tobacco use among college students increased substantially during the 1990s. Better understanding of college smokers is warranted to develop interventions specific to the needs of this population. We examined sociodemographic and tobacco-use characteristics associated with self-identification as a regular smoker and intentions to quit smoking among college students who smoke cigarettes. We conducted logistic regression analysis on baseline survey data from the Campus Health Action on Tobacco study, a 4-year group-randomized trial at 30 four-year colleges in Washington, Oregon, and Idaho. Students who self-identified as a regular smoker smoked more cigarettes before starting college, smoked a greater number of cigarettes the prior 30 days, smoked more cigarettes per day, and were more likely to smoke within 30 min of waking up, compared with students who were current smokers but did not consider themselves regular smokers. Females, older students, and those who had decreased the amount they smoked since coming to college were more likely to want to quit "very much." Females and students in early college years were more likely to be planning to quit before graduation, as were students who had decreased the amount they smoked since coming to college. Interventions should target students who are in their early college years, given that habits prior to college, changes in smoking habits while in college, and year in college are associated with students' self-identification as a regular smoker, desire to quit smoking, or plan to quit smoking while in college.

Abstract
INTRODUCTION: Decompression sickness (DCS) results from the formation of bubbles within the tissues and blood in response to a reduction in environmental pressure. Venous gas emboli (VGE) are common after diving and are usually only present in small numbers. Greater VGE numbers are an indication of decompression stress, and can be reliably detected using ultrasound imaging. AIM: To examine the relationship between production of VGE following a routine dive and the risk of DCS. METHODS: A matched population of divers with and without a history of DCS were monitored for the production of VGE at 15-minute intervals using ultrasound, following a 405 kPa air dive in a hyperbaric chamber using the DCIEM air decompression table. VGE production was graded using a validated grading system and the data analysed to compare maximum VGE grade and duration of VGE formation. RESULTS: Eleven divers with a history of DCS were compared with 13 divers with no history of DCS. Divers with a history of DCS demonstrated both a higher maximum grade (P=0.04) and longer duration (P=0.002) of VGE production compared to divers without a history of DCS. CONCLUSION: Higher maximum VGE grades and longer durations of VGE following decompression were associated with a history of DCS and, in particular, musculoskeletal DCS. Although the exact mechanism of DCS remains poorly understood, our data suggest some individuals are inherently more prone to develop VGE, increasing the probability of DCS. Modification of diving practices in those with high VGE grades could potentially decrease DCS risk in these individuals.

Abstract
BACKGROUND: Computed tomography-adapted Leaman score (CT-LeSc) was developed to quantify coronary CT angiography information about atherosclerotic burden (lesion localization, stenosis degree, and plaque composition). The objective of the study is to evaluate CT-LeSc long-term prognostic value in patients with suspected coronary artery disease (CAD). METHODS AND RESULTS: Single-center prospective registry including 1304 consecutive patients undergoing coronary CT angiography for suspected CAD. High CT-LeSc was defined by upper tertile (score, >5) cutoff. Segment involvement score and segment stenosis score were also evaluated. Hard cardiac events (cardiac death and nonfatal acute coronary syndromes) were considered for analysis. Different Cox regression models were used to identify independent event predictors. Kaplan-Meier event-free survival was evaluated in 4 patient subgroups stratified by obstructive (>/=50% stenosis) versus nonobstructive CAD and a high (>5) versus a low (=5) CT-LeSc. Of 1196 patients included in the final analysis (mean follow-up of 52+/-22 months), 125 patients experienced 136 hard events (18 cardiac deaths and 118 nonfatal myocardial infarction). All atherosclerotic burden scores were independent predictors of cardiac events (hazard ratios of 3.09 for segment involvement score, 4.42 for segment stenosis score, and 5.39 for CT-LeSc). Cumulative event-free survival was 76.8% with a high CT-LeSc and 96.0% with a low CT-LeSc. Event-free survival in nonobstructive CAD with high CT-LeSc (78.6%) was similar to obstructive CAD with high CT-LeSc (76.5%) but lower than obstructive CAD with low CT-LeSc (80.7%). CONCLUSIONS: CT-LeSc is an independent long-term predictor of hard cardiac events. Patients with nonobstructive CAD and high CT-LeSc had hard event-free survival similar to patients with obstructive CAD.

Abstract
BACKGROUND: The Food and Drug Administration can set standards that reduce the nicotine content of cigarettes. METHODS: We conducted a double-blind, parallel, randomized clinical trial between June 2013 and July 2014 at 10 sites. Eligibility criteria included an age of 18 years or older, smoking of five or more cigarettes per day, and no current interest in quitting smoking. Participants were randomly assigned to smoke for 6 weeks either their usual brand of cigarettes or one of six types of investigational cigarettes, provided free. The investigational cigarettes had nicotine content ranging from 15.8 mg per gram of tobacco (typical of commercial brands) to 0.4 mg per gram. The primary outcome was the number of cigarettes smoked per day during week 6. RESULTS: A total of 840 participants underwent randomization, and 780 completed the 6-week study. During week 6, the average number of cigarettes smoked per day was lower for participants randomly assigned to cigarettes containing 2.4, 1.3, or 0.4 mg of nicotine per gram of tobacco (16.5, 16.3, and 14.9 cigarettes, respectively) than for participants randomly assigned to their usual brand or to cigarettes containing 15.8 mg per gram (22.2 and 21.3 cigarettes, respectively; P

Abstract
Background: Water distribution systems have been demonstrated to be a major source of nosocomial legionellosis. We describe an outbreak in our institution in which a novel source of Legionella pneumophila was identified in the plumbing system. Methods: After an outbreak of 10 cases of legionellosis in our hospital, recommended measures including superheating of the hot water to 80° C, hyperchlorination to 2 ppm, and flushing resulted in no new cases in the following 5 years. Recently, despite these control measures, three new cases occurred. Surveillance cultures of shower heads and water tanks were negative; cultures of tap water samples remained positive. This prompted a search for another reservoir. Shock absorbers installed within water pipes to decrease noise were suspected. Results: One hundred twenty-five shock absorbers were removed and cultured. A total of 13 (10%) yielded heavy growth of L. pneumophila (serogroup 1). Since their removal, no new cases have been found and the percentage of positive results of random tap water culture has dropped from 20% to 5%. Conclusions: This is the first report that identifies shock absorbers as a possible reservoir for L. pneumophila. We recommend that institutions with endemic legionellosis assess the water system for possible removal of shock absorbers.

Abstract
BACKGROUND: Gastric cancer is the second leading cause of cancer death worldwide and occurs most frequently in the age group of 5070 years. Rarely reports have appeared regarding younger age groups. The purpose of this study was to compare clinical characteristics and outcome of treatment between young and elderly patients with gastric cancer in Thailand. MATERIALS AND METHODS: Clinical information, histological features, endoscopic findings and treatment outcome were reviewed and collected from Thammasat University Hospital, Pathumthani and Bangkok Medical Center, Bangkok, Thailand between September 2011March 2015. RESULTS: A total of 154 gastric tumor patients including 101 with benign tumors (22 males and 79 females, mean age= 62.6 years) and 53 with gastric cancers (27 males and 26 females, mean age= 60.6 years) were enrolled in this study. Gastric cancer patients presented with alarm symptoms such as anemia, anorexia and weight loss significantly more frequently than benign gastric tumor patients. In gastric cancer patients, mean duration of symptoms prior to diagnosis was shorter in younger (/=40 years) (73.3 days vs 84.8 days). Family history of GI malignancy and diffuse type of gastric cancer were significant greater in younger than older patients (36% vs 5% P=0.01; OR= 11.4, 95%CI = 1.874.7 and 73% vs 14%, P

Abstract
Microdilution method that determines the minimum inhibitory concentrations (MIC) of antifungal agents against Candida spp. is still the only method used in laboratories for both biofilm and planktonic forms. However, it was determined in several studies that there were susceptibility differences between the biofilm and planktonic forms of the same microorganism. The aims of this study were the determination of in vitro susceptibilities of planktonic and biofilm forms of Candida strains against antifungal agents, the comparison of the data obtained from planktonic and biofilm forms and the evaluation of two different methods used for the detection of susceptibilities of biofilm forms. Candida albicans ATCC 10231, Candida parapsilosis ATCC 90028 and Candida krusei ATCC 6258 were used as reference strains together with clinical isolates of one of each C.albicans, C.parapsilosis and Candida tropicalis. Microdilution method was used to determine the susceptibilities of planktonic forms of the strains according to CLSI M27-A3 standards, and MIC values of fluconazole, itraconazole, flucytosine, amphotericin B and nystatin were determined. For the detection of antifungal susceptibilities of Candida spp. biofilm forms, Calgary biofilm method (CBM) and BioTimer assay (BTA) were used, and minimum biofilm eradication concentration (MBEC) and minimum biofilm inhibition concentration (MBIC) values of the same antifungals were determined. The difference between MIC and CBM-MBEC, CBM-MBEC and BTA-MBEC, CBM-MBEC and BTAMBIC values were found statistically significant (p 0.05) for the other antifungal agents. These findings supported that antifungal susceptibilities of biofilm forming Candida strains should also be investigated. However, MBEC and MBIC of the antifungal agents should not always be expected to be higher than the MIC values since the mechanism of action of the specific antifungal agents and the first inoculum concentration of the microorganisms might differ.

Abstract
Determination of analytes at trace levels in complex samples (e.g. biological or contaminated water or soils) are often required for the environmental assessment and monitoring as well as for scientific research in the field of environmental pollution. A limited number of analytical techniques are sensitive enough for the direct determination of trace components in samples and, because of that, a preliminary step of the analyte isolation/enrichment prior to analysis is required in many cases. In this work the newest trends and innovations in liquid phase microextraction, like: single-drop microextraction (SDME), hollow fiber liquid-phase microextraction (HF-LPME), and dispersive liquid-liquid microextraction (DLLME) have been discussed, including their critical evaluation and possible application in analytical practice. The described modifications of extraction techniques deal with system miniaturization and/or automation, the use of ultrasound and physical agitation, and electrochemical methods. Particular attention was given to pro-ecological aspects therefore the possible use of novel, non-toxic extracting agents, inter alia, ionic liquids, coacervates, surfactant solutions and reverse micelles in the liquid phase microextraction techniques has been evaluated in depth. Also, new methodological solutions and the related instruments and devices for the efficient liquid phase micoextraction of analytes, which have found application at the stage of procedure prior to chromatographic determination, are presented.
