Background: This study aimed to determine the prevalence and factors related to needle stick injuries (NSIs) and to assess related safety measures among a sample of Iranian nurses. Methods: In this cross-sectional study, a random sample of 168 registered active nurses was selected from different wards of one of the hospitals of Shiraz University of Medical Sciences (SUMS). Data were collected by an anonymous questionnaire and a checklist based observational method among the 168 registered active nurses. Results: The prevalence of NSIs in the total of work experience and the last year was 76% and 54%, respectively. Hollow-bore needles were the most common devices involved in the injuries (85.5%). The majority of NSIs occurred in the morning shift (57.8%) and the most common activity leading to NSIs was recapping needles (41.4%). The rate of underreporting NSIs was 60.2% and the major reasons for not reporting the NSIs were heavy clinical schedule (46.7%) and perception of low risk of infection (37.7%). A statistically significant relationship was found between the occurrence of NSIs and sex, hours worked/week, and frequency of shifts/month. Conclusion: The study showed a high prevalence of NSIs among nurses. Supportive measures such as improving injection practices, modification of working schedule, planning training programs targeted at using personal protective equipment, and providing an adequate number of safety facilities such as puncture resistant disposal containers and engineered safe devices are essential for the effective prevention of NSI incidents among the studied nurses.

Background: Shoulder instability procedures have low morbidity; however, complications can arise that result in readmission to an inpatient healthcare facility. The purpose of this study is to identify the demographics and risk factors associated with unplanned 30-day readmission and reoperation following arthroscopic and open treatment for shoulder instability. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried to find patients who underwent shoulder instability surgery from 2015 to 2019. Independent sample Student t-tests, chi-square, and (where appropriate) Fisher's exact tests were used in univariate analyses to identify demographic, lifestyle, and perioperative variables related to 30-day readmission and reoperation following repair for shoulder instability. Multivariate logistic regression modeling was subsequently performed. Results: Of the 11,230 cases included in our sample, only 0.54% were readmitted, and 0.23% underwent reoperation within the 30-day postoperative period. Multivariate logistic regression modeling confirmed that the following patient variables were associated with statistically significantly increased odds of readmission and reoperation: open repair, congestive heart failure (CHF), and hospital length of stay. Conclusions: Unplanned 30-day readmission and reoperation after shoulder instability surgery is infrequent. Patients with American Society of Anesthesiologists class II, CHF, longer than average hospital length of stay, or an open procedure have higher odds of readmission than patients without those factors. Patients who have CHF, longer than average hospital length of stay, and open surgery have higher odds of reoperation than others. Arthroscopic procedures should be used to manage shoulder instability, if possible. Level of evidence: III.

우리나라 자살률은 Organization for Economic Cooperation and Development 국가 중 압도적 1위이며, 특히 아동·청소년들은 삶의 만족도가 낮고, 자살률 또한 매년 증가하고 있다. 아동·청소년 시기는 어느 발달단계보다 격동적이고 충동적인 시기로 자살 그 자체가 치명적이고, 전염성이 높다. 또한 의미 있는 작업을 잃어버렸을 경우에도 자살률이 높은데, 이는 자살고위험군 아동·청소년도 마찬가지이다. 정신건강복지법이 개정되고, 정신건강전문요원에 작업치료사가 포함되기 시작하면서 정신건강서비스에 있어 작업치료를 포함한 다학제적 접근이 강조되고 있다. 아동·청소년 자살을 막기 위한 선별도구로 자살사고척도(Suicidal Ideation Questionnaire), Beck의 자살사고척도(Beck Scale for Suicide Ideation), 콜롬비아 대학 자살 심각성 평가 척도(Columbia-Suicide Severity Rating Scale), 청소년용 삶의 이유척도(The Reasons for Living Inventory for Adolescents), 학생 정서·행동 특성검사(Student Emotional and Behavioral Screening Test)가 사용되었고, 작업치료평가도구인 Canadian Occupational Performance Measure도 사용되었다. 또한 다양한 학문과 기관에서 다양한 자살예방프로그램이 제시되고 있다. 하지만 자살고위험군 현실적 특성상 신속하고 적기에 서비스를 제공해야 하기 때문에 다른 자살예방프로그램보다 상대적으로 그 수가 적으며 이 또한 대부분 인지행동적 측면에 초점이 맞춰져 있다. 따라서 본 연구는 아동·청소년 자살고위험군을 대상으로 정신건강서비스를 제공하는 전문가들에게 다양한 자살예방프로그램을 소개하고, 각기 처해 있는 실정에 맞게 현장에서 활용할 수 있도록 하는 데 목적이 있다.

The ABO blood group has been recently proposed to influence development of oral cancer. The aim ofthis study was to evaluate the association between the type of ABO blood group and oral cancer. In a case-control study, 104 patients with oral cancer were compared with 90 blood donors without cancer as controls. Data regarding the patient demographics, blood groups, Rh status, cancer characteristics and oral habits were also compared between two subgroups of squamous and non-squamous oral cancers. For statistical analysis, Chi-square test, t-student Test and Logistic Regression were used to analyze the relationship between ABO blood groups and oral cancer. The frequency of blood group B was significantly higher in oral cancer patients than controls (32% vs 13%) (p value=0.01), but Rh factor did not show significant difference between cases and controls. According to Logistic Regression, people with blood group B and those older than 50 had 3.5 and 19.4 times elevated risk of developing oral cancer, respectively. The frequency of squamous cell cancer was also significantly higher in men and people older than 50. On the other hand, females, people under 50, and those with blood group B were at 5.6, 2.9 and 4.3 times higher risk of developing non-squamous cell oral cancer,respectively. People with blood group B are at a greater risk of developing oral cancer, and female patients under 50 years of age with blood group B have the highest risk to develop non-squamous cell oral cancer.

Background: Breast Cancer (BCa) is the most common malignant tumour in Mexican women. In BCa, several studies have linked ${\beta}2-adrenergic$ receptor activation with increased tumour growth and progression as related with Epinephrine-NorEpinephrine (E-NE) stimulation. The aim of this study was to describe Beta-Blocker (BB) treatment related with reduction of the risk of metastasis in Mexican patients with BCa. Materials and Methods: We collected data of 120 patients seen at the High-Specialty Naval General Hospital in Mexico City (HOSGENAES), all of these with a histopathological diagnosis of BCa. Four groups of patients were divided as follows: without Systemic Arterial Hypertension (SAH); with SAH treatment with non-selective BB; with SAH treatment with selective BB, and with SAH treatment with other antihypertensive drugs. Chi-square, Mantel-Haenszel, Student t, and ANOVA tests were performed for data analysis. Results: On average, patients were $54.8{\pm}11.8$ years of age. Risk factors such as smoking and consuming alcohol exhibited a frequency of 33 and 36.5% respectively. Clinical stages III- IV were found in 50% of patients, while, 30% of patients had arterial hypertension (n=29 and N=96, respectively) and 17.5% used BB. One hundred percent of patients with arterial hypertension treated with BB for ${\beta}1$ - and ${\beta}2$ -adrenergic-receptors did not present metastasis globally, but patients treated with ${\beta}1$ BB presented 30% of metastasis while patients treated with no BB or without SAH had around 70% of metastasis. Conclusions: In Mexican patients with BCa and SAH treated with non-selective (${\beta}1$- and ${\beta}2-adrenergic$ receptors) BB, a decrease in the risk for metastasis was observed at the time of diagnosis.

Purpose: Along with the country's decreasing birth rate, many South Korean women are currently facing the issue of high risk pregnancy. Despite the increasing number of women who prefer to get married at an older age, fewer of them are aware of how to prepare for healthy pregnancy at such age. The following study has been conducted to check the level of awareness and educational demand regarding healthy pregnancy among female university students who are not majoring in medical fields. Methods: Google Forms was used to survey 245 female students attending a university located in the Province of Gyenongi. We asked about their attitudes to and knowledge of pregnancy, their lifestyle, and the demand for pregnancy education. Results: The average age of the participants was 20.4 years. Although the majority of the correspondents answered that they have received education about pregnancy before, many of them displayed a low level of knowledge regarding pregnancy. On contrast, the demand for education about pregnancy and high risk pregnancy was high. Conclusion: For healthier pregnancy and childbirth, more preparation is needed before entering pregnancy. Management programs to be given prior to pregnancy should be developed to promote the knowledge and awareness of healthy pregnancy.

Background: A permit to work (PTW) is a formal written system to control certain types of work which are identified as potentially hazardous. However, human error in PTW processes can lead to an accident. Methods: This cross-sectional, descriptive study was conducted to estimate the probability of human errors in PTWprocesses in a chemical plant in Iran. In the first stage, through interviewing the personnel and studying the procedure in the plant, the PTW process was analyzed using the hierarchical task analysis technique. In doing so, PTWwas considered as a goal and detailed tasks to achieve the goal were analyzed. In the next step, the standardized plant analysis risk-human (SPAR-H) reliability analysis method was applied for estimation of human error probability. Results: The mean probability of human error in the PTW system was estimated to be 0.11. The highest probability of human error in the PTW process was related to flammable gas testing (50.7%). Conclusion: The SPAR-H method applied in this study could analyze and quantify the potential human errors and extract the required measures for reducing the error probabilities in PTW system. Some suggestions to reduce the likelihood of errors, especially in the field of modifying the performance shaping factors and dependencies among tasks are provided.

Background & Objectives: The most northern and northwestern regions of Iran are at a high risk for gastric cancer. The aim of this study was to assess the general population's awareness about risk factors, symptoms and signs, preventive methods and management of gastric carcinoma in a high prevalence city in the North of Iran. Methods: A cross-sectional population-based telephone survey which was conducted on 3,457 residents of Rasht, the capital city of Guilan Province, to assess their awareness regarding gastric carcinoma. The questionnaires contained demographic data and statements on respondents' knowledge about risk factors, symptoms and signs, prevention and management of gastric cancer which were filled by general practitioners after asking the subjects. Data were analyzed in SPSS14. P<0.05 was considered significant. Results: The mean knowledge score of the respondents was $5.05{\pm}1.37$ regarding risk factors of gastric carcinoma, $4.39{\pm}1.99$ regarding symptoms and signs, $6.0{\pm}1.22$ regarding preventive strategies, and $1.6{\pm}1.16$ regarding management. Totally the mean knowledge level of the respondents toward gastric carcinoma would be $17.1{\pm}3.97$ from the maximum grade of 29. The age group of 45-55 y/o, bachelor degree and higher, physicians and nurses, those who had cancer history in friends or had the history of gastrointestinal diseases showed significantly higher knowledge scores (P=0.001). Conclusion: There is a general lack of awareness of cancer risk factors, symptoms and signs, methods of prevention, and importance of early diagnosis and treatment. Educational programs should be developed to promote adherence to recommended screening guidelines.

Purpose: The purpose of the study was to survey male high school students on their MERS(Middle East Respiratory Syndrome)-related knowledge, risk perception, and health behaviors and to identify the factors affecting health behaviors during the MERS outbreak in Korea. Methods: The subjects in this study were 144 students in a male high school. Data were collected through self-reported questionnaires in July, 2015. The collected data were analyzed by ANOVA, Pearson's correlation and multiple regression using SPSS/WIN 21.0. Results: The proportion of correct answers to questions testing MERS-related knowledge was 71.6% among male high school students; their health behaviors were rated at 48.9%; and their risk perception rate was 1.8 out of 4. There was a positive correlation between knowledge, risk perception, and health behaviors. Knowledge and risk perception explained 15.1% of the variance in health behaviors. Conclusion: To improve students' health behaviors, their risk perception and knowledge over MERS should be strengthened. Therefore, it is necessary to develop and implement efficient and feasible MERS education programs for high school students.
