Gambling behavior in alcohol-serving and non-alcohol-serving-venues: a study of electronic gaming machine players using account records

Aim: Contextual factors, such as venue characteristics appear to influence gambling behavior. However, few studies have compared the relationship between gambling behavior in alcohol-serving venues (ASVs) and non-alcohol serving venues (NASVs). The aim of the study was to examine individual gambling behavior in ASVs and NASVs. Method: A repeated-measures design was used to examine individual gambling behavior in ASVs and NASVs covering a month. The sample comprised 1,452 observations of 726 individuals (25.2% female). A quantile regression model was conducted to examine individual differences in gambling behavior (number of days, sessions, bets made, stake and time spent, net balance, and average bet size) across ASVs and NASVs. Analyses were broken down by gambler category (those that reached legal mandatory spending limits and those that did not) as well as on time frame (overall gambling behavior and average in-session gambling behavior). Results: Individuals gambled regularly in NASVs and occasionally in ASVs. Compared to NASVs, in-session gambling behavior was more variable in ASVs. In-session analysis showed that non-limit reaching gamblers staked less money in ASVs than in NASVs but lost more money in ASVs than in NASVs. Limit reaching gamblers showed no differences in gambling behavior across venues. Conclusion: The findings show that in-session gambling behavior is more variable in ASVs compared to NASVs regardless of gambling category. Non-limit reaching gamblers may be more sensitive to contextual factors than limit reaching gamblers and appear to be more willing to take more risk in ASVs compared to NASVs. The contextual implications are discussed

Verification of Snapshotable Trees using Access Permissions and Typestate

Abstract. We use access permissions and typestate to specify and verify a Java library that implements snapshotable search trees, as well as some client code. We formalize our approach in the Plural tool, a sound modular typestate checking tool. We describe the challenges to verifying snapshotable trees in Plural, give an abstract interface specification against which we verify the client code, provide a concrete specification for an implementation and describe proof patterns we found. We also relate this verification approach to other techniques used to verify this data structure.

Empowering patient education on self-care activity among patients with colorectal cancer - a research protocol for a randomised trial

Background: Chemotherapy-induced side effects may have a negative effect on nutrition intake, thus increasing the risk of malnutrition and consequently, other serious complications for patients with cancer. The prevalence of malnutrition is common among patients with colorectal cancer. Nurse-led empowering education may have a positive effect on self-care activity in this patient group. Therefore, our purpose is to develop an empowering educational nursing intervention and test its effect on self-care activation and knowledge level among patients with colorectal cancer during chemotherapy. Secondary outcomes are quality of life and risk of malnutrition. Methods: An interdisciplinary expert group developed a face-to-face empowering educational intervention using teach-back method. A two-arm, single-centre, superiority trial with stratified randomisation (1:1) and pre-post measures will be used to assess the effect of the intervention compared to standard care. Patients (N = 40 + 40) will be recruited in one university hospital outpatient clinic in Finland. Eligibility criteria are adult patients diagnosed with colorectal cancer starting oral fluoropyrimidine or combination chemotherapy treatment. A registered nurse experienced in oncology will deliver the intervention 2 weeks after the first chemotherapy. Outcomes are measured before intervention (M0) and after a two-month follow-up period (M1). Discussion: This study will assess whether nurse-led empowering education using teach-back method is effective on self-care activity among patients with colorectal cancer. If the intervention has a positive effect, it may be implemented into patient education in a corresponding context.Peer reviewe

Sinus Barotraumas in Commercial Aircrew

BACKGROUND: Sinus barotraumas are a common condition in aviation medicine, sometimes compromising flight safety and even permanently grounding aircrew. Considering this and the ever-increasing amount of commercial aviation, a thorough examination is required. METHODS: In this survey study, an anonymous, electronic questionnaire was distributed to commercial aircrew of the three major commercial airlines operating in Finland (N = 3799), covering 93% of the target population (i.e., all commercial aircrew operating in Finland, N = 4083). Primary outcomes were self-reported prevalence, clinical characteristics, and health and occupational effects of sinus barotraumas in flight. Secondary outcomes were adjusted odds ratios (OR) for frequency of sinus barotraumas with respect to possible risk factors. RESULTS: Response rate was 47% (N = 1789/3799), with 61% (N = 1088) of the respondents having experienced sinus barotraumas in flight. Of those affected, 59% had used medications, 18% had undergone surgical procedures, and 53% had been on sick leave due to sinus barotraumas (38% during the last year) in flight. Factors associated with sinus barotraumas were female sex [OR, 2.47; 95% confidence interval (CI) 1.35-4.50] and a high number of upper respiratory tract infections (>= 3 vs.Peer reviewe

Middle Ear Barotraumas in Commercial Aircrew

BACKGROUND: Middle ear (ME) barotraumas are the most common condition in aviation medicine, sometimes seriously compromising flight safety. Considering this and the ever-increasing amount of commercial aviation, a detailed overview is warranted. METHODS: In this survey study, an anonymous, electronic questionnaire was distributed to commercial aircrew of the three major commercial airlines operating in Finland (N = 3799), covering 93% of the target population (i.e., all commercial aircrew operating in Finland, N = 4083). Primary outcomes were self-reported prevalence, clinical characteristics, and health and occupational effects of ME barotraumas in flight. Secondary outcomes were adjusted odds ratios (OR) for frequency of ME barotraumas with respect to possible risk factors. RESULTS: Response rate was 47% (N = 1789/3799), with 85% (N 1516) having experienced ME barotraumas in flight. Of those affected, 60% had used medications, 5% had undergone surgical procedures, and 48% had been on sick leave due to ME barotraumas (40% during the last year). Factors associated with ME barotraumas included a high number of upper respiratory tract infections [>= 3 URTIs/yr vs. 0 LIRTIs/yr: OR, 9.02; 95% confidence interval (CI) 3.99-20.39] and poor subjective performance in Valsalva ("occasionally" vs."a lways" successful: OR, 7.84; 95% CI 3.97-15.51) and Toynbee ("occasionally" vs."always" successful: OR, 9.06; 95% CI 2.67-30.78) maneuvers. CONCLUSION: ME barotraumas were reported by 85% of commercial aircrew.They lead to an increased need for medications, otorhinolaryngology-related surgical procedures, and sickness absence from flight duty. Possible risk factors include a high number of URTIs and poor performance in pressure equalization maneuvers.Peer reviewe

Patients’ involvement in nursing students’ clinical education: A scoping review

BACKGROUND: Actual contacts with patients are crucial in developing the skills that students need when working with patients. Patients are accustomed to the presence of students. The concept of learning from patients has emerged recently, shifting the focus from learning from professionals as role models to the relationship between the student and patient.AIM: With focus on patients' perspective in clinical practice placements, this scoping review aims to review and summarize the existing empirical literature regarding patients' involvement in nursing students' clinical education.DESIGN AND METHOD: A broad search without time limitations was performed in the databases CINAHL, Medline, PsycINFO and ERIC. A manual search was also performed. Only empirical studies describing aspects of patient involvement in nursing education from the patient's perspective were taken into account. Thirty-two studies published from 1985 to June 2016 met the selection criteria and were analysed using inductive content analysis.RESULTS: The perspective of real patients focused on their role in students' learning and assessment processes. In general, patients appreciated the opportunity to contribute to a student's learning process and thus enhance the quality of patient care. However, the patients' approaches varied from active to passive participants, comprising active participants contributing to students' learning, followers of care and advice, and learning platforms with whom students practiced their skills. Some patients perceived themselves as active participants who facilitated students' learning by sharing knowledge and experience about their own care and wellbeing as well as assessed students' performance by providing encouraging feedback.CONCLUSION: The state and degrees of patient involvement in nursing students' clinical education were made explicit by the literature reviewed. However, the number of studies examining the involvement of real patients in students' education in clinical settings is very limited. To understand this untapped resource better and to promote its full realization, recommendations for nursing education and future research are made.</p
