RESUMO
BACKGROUND: Coronary artery disease (CAD) is an atherosclerotic disease of an inflammatory nature. Previous studies examining the relationship between triglycerides and high-density lipoprotein cholesterol have highlighted the importance of plasma atherogenic index (AIP) as an important predictor of coronary heart disease. However, due to the lack of adequate information on this topic, this study aimed to investigate the relationship between AIP and coronary heart disease risk. RESULTS: This study included 2,226 women and 1,690 men aged 35-70 years who participated in the Bandar Kong Cohort study and met the eligibility criteria. The data was collected using a checklist and questionnaires, which were designed by experienced individuals. After participants completed a registration form and gave informed consent, face-to-face interviews were conducted by trained experts. The validity and reliability of the questionnaire had been verified by the national cohort team prior to its use. The Ethics Committee of Hormozgan University of Medical Sciences (IR.HUMS.REC.1400.171) approved the study. Data from the initial cohort survey using SPSS software version 25, were analyzed to include several factors, including age, sex, smoking status, body mass index (BMI), physical activity level, socioeconomic status, AIP, systolic blood pressure, and diastolic blood pressure. The prevalence of coronary heart disease was found to be 7.5% higher in people with a BMI of 25 or higher. Also, Individuals with low physical activity had a higher prevalence. Individuals with CAD had significantly higher mean values for the AIP, age, systolic blood pressure, and diastolic blood pressure (0.46, 57.50, 128.43, and 81.10, respectively) compared to those without CAD. Furthermore, patients with CAD had lower years of education (2649.45 and 3.59) than individuals without CAD (P < 0.05). Importantly, our findings showed that AIP increased the odds ratio of coronary heart disease by 1.86 as an independent risk factor. CONCLUSIONS: Based on our investigation, the AIP is a valuable and independent predictive risk factor for coronary artery disease. This index can be utilized effectively due to its accessibility and affordability, making it a promising tool for risk assessment in clinical settings.
RESUMO
Cancer is a global health concern and affects patient quality of life, anxiety, depression, and sleep. Physical exercise shows promise in alleviating these effects. Karate is a holistic intervention that could be used to improve several outcomes related to cancer disease, but to date its effect remains unexplored. This quasi-experimental pre-/poststudy evaluated the effects of a 6-month karate program conducted twice a week for 60 minutes each session on quality of life, anxiety, depression, sleep quality, and psychosomatic symptoms in 22 patients with posttherapy oncology. Significant improvements in quality of life (P = .006), anxiety (P < .001), depression (P < .001), and sleep quality (P = .011) were observed. Multidimensional psychophysical evaluation showed significant reductions in symptoms (P < .05). High participant satisfaction was reported across all dimensions. This pilot study shows the potential benefits in oncology patients, but more research is necessary to confirm these findings.

Background: Hookah smoking has pointedly increased worldwide and could have different harmful health effects. However, long term hookah smoking effects on chronic diseases has not been well studied. This study was aimed to investigate the relationship between hookah smoking with metabolic syndrome and diabetes. Methods: In this prospective study, the baseline data from 3695 participant (35-70 years old) of Bandar-e-Kong cohort study in Hormozgan province, Iran were used. In this study, data were collected through the questionnaires designed in the Kong cohort study and 25 mm of blood sample. All analyses were performed using SPSS version 27.0 and the ggplot2 package in RStudio version 2023.06.1 + 524. p < 0.05 was considered a significant difference. Results: The prevalence of hookah smoking was 17.3% in total. Also, the prevalence of metabolic syndrome, diabetes, hypertension, and dyslipidemia were 35.6, 15.2, 31.2, and 78.0%, respectively. Our results showed that there were statistically significant relationship between hookah smoking and metabolic syndrome, hypertension and diabetes (p < 0.05). In the case of dyslipidemia, hookah smoking was also associated with increase in dyslipidemia (p < 0.05). Conclusions: More evidence is needed to understand the mechanism of hookah smoking and these health effects. As well as, health education and increasing public awareness about the health effects of hookah smoking and implementation of smoking prohibition policies are highly recommended.
RESUMO
BACKGROUND: Human resources are the most important organizational resources and play the most important role in the production and productivity cycle. Considering the importance of people's health and the study of their burnout as a possible cause of occupational cognitive failures, this study aimed to investigate the relationship between burnout, cognitive failure, and general health. PARTICIPANTS AND PROCEDURE: A cross-sectional-analytical study was conducted in Iran Tire Factory. The statistical population of this study was 302 personnel who were randomly selected. Data were collected by four valid questionnaires (demographic information, Maslach burnout, cognitive failure, and general health questionnaire). Then data were analyzed using SPSS software. RESULTS: The results of the analysis revealed a significant and direct relationship between burnout and cognitive failure (p < .001), and a significant inverse relationship was found between cognitive failure and physical health (p = .022). The other results showed that emotional exhaustion and depersonalization dimensions are significantly associated with cognitive failure (p < .001, p = .016). CONCLUSIONS: According to the results of this study, burnout causes cognitive failures among factory personnel and on the other hand, cognitive failures affect the physical health of individuals and lead to deterioration of physical health, which in turn can reduce a person's performance and reduce work efficiency.
RESUMO
Background: Elevated low-density lipoprotein cholesterol (LDL-C) is a significant risk factor for cardiovascular diseases. LDL-C can be directly measured using various methods, but this requires expensive equipment. Currently, clinical laboratories estimate LDL-C based on Friedewald's formula (FF). We aimed to develop a modified formula based on directly measured LDL-C (D-LDL-C) values in a large population in Southern Iran and compare the results with various other estimation formulas. Methods: The participants of this cross-sectional study were adults aged >18 years living in Southern Iran. Blood samples from 15,200 individuals were collected, and the measured lipid parameters were randomly divided into training (n=10,184) and validation (n=5,016) datasets. A new formula was developed using a linear regression model, and its accuracy was validated. Pearson's correlation and Cohen's kappa were used to determin the relationship between D-LDL-C and calculated LDL-C (C-LDL-C). Results: The developed formula for the estimation of LDL-C was 0.857 total cholesterol (TC)-0.915 high-density lipoprotein cholesterol (HDL-C)-0.115 triglycerides (TG). Based on our proposed formula, for TG<150 and TG≥150 mg/dL, there was a significant correlation between mean values of D-LDL-C and C-LDL-C (r=0.985 and r=0.974, respectively). Compared to other formulas, C-LDL-C obtained from the proposed formula had the highest correlation with D-LDL-C. The agreement between D-LDL-C and C-LDL-C for TC<200, 200-239, and ≥240 mg/dL was 80.8%, 63.2%, and 67.4%, respectively, indicating a higher level of agreement than other formulas. Conclusion: The new formula appears to be more accurate than FF when applied to the population of Southern Iran.

BACKGROUND: Equitable care is a fundamental value in the nursing profession. Healthcare workers have both a moral and professional duty to ensure that they do not discriminate. AIM: This study aimed to explore how patients perceive equitable nursing care. RESEARCH DESIGN, PARTICIPANTS, AND RESEARCH CONTEXT: This descriptive phenomenological qualitative research study used purposeful sampling to select 17 patients from various departments of a general hospital in southern Iran. The participants were then interviewed using a semi-structured in-depth interview format, which aimed to delve into their experiences with equitable nursing care. The collected data were analyzed using Colaizzi's seven-step method and MAXQDA20 software. ETHICAL CONSIDERATIONS: Oral and written information about the study was provided before the participants gave their written consent. The transcribed interviews were de-identified. The study was approved by the Ethics Committee of Jiroft University of Medical Sciences. FINDINGS: The data analysis of the study identified three main themes and six subthemes that were related to the experiences of patients with equitable nursing care. The first theme, equitable care, encompassed subthemes such as nurses' dedicated efforts to facilitate patient recovery and adherence to ethical behavior. The second theme, unconscious causes of inequitable nursing care, included subthemes such as unintentional discrimination stemming from organizational constraints and unconscious biases resulting from a lack of knowledge and skills. The third theme, discriminatory care, comprised subthemes such as deliberate discrimination based on personal traits and selective discrimination. CONCLUSION: The study findings indicate that achieving equitable nursing care requires a multifaceted approach. This includes effective hospital management, organizational reforms, and regulatory enhancements. Additionally, it is crucial to pay close attention to the needs of patients, enhance nurses' theoretical and practical skills in providing equitable care, fostering a culture of equality within healthcare settings, and consider the personality dimensions and moral characteristics of nurses.
RESUMO
Considering the harmful effects of smoking on oral and dental health, our aim was to investigate the oral and dental health status of people in the city of Bandare-Kong, Iran, and its relationship to smoking. This cross-sectional population-based study used baseline data from the Bandare-Kong Cohort Study. A total of 4063 participants aged 35-70 years were included in this study. Using Stata17 software, negative binomial regression was employed to identify factors related to the decayed, missing, and filled teeth (DMFT) index. The association between smoking status and DMFT was assessed by the adjusted incidence rate ratio (IRR). Of the 4063 participants, 987 (24.29%) used cigarettes, hookahs, or both. The mean ± standard error (SE) DMFT index in all subjects was 11.08 ± 0.15; it was 14.17 ± 0.53 for cigarette smokers and 12.39 ± 0.37 for hookah users (p < 0.001). After adjusting for other variables, the rate of DMFT for cigarette smokers was 0.33 (IRR: 1.33; 95% confidence interval [CI]: 1.22, 1.44), which was higher than for those who did not use cigarettes. The rate of DMFT for those who used cigarettes, hookahs, or both was 0.11 (IRR: 1.11; 95% CI: 1.05, 1.18), which was also higher than for those who did not smoke. Cigarette smoking is a risk factor for oral health complaints. Although the rate of DMFT was increased in hookah smokers, it was not a predictor of dental problems. However, we suggest that hookah use be included in educational policies to control oral and dental diseases.
RESUMO
BACKGROUND: Ectopic pregnancy (EP) has many adverse effects on the relationship between couples. The present study aims to assess the association between sexual function (SF), quality of marital relationship (QMR) and associated factors in women with a history of EP. METHOD: This cross-sectional study was performed on 220 women with a history of EP in Kerman in 2022. Convenience sampling method was applied. Data were collected using the female sexual function index (FSFI) and the perceived relationship quality components scale (PRQC) questionnaires and were analyzed with descriptive and inferential statistics (median regression) in Stata software version 17. A P-value < 0.05 was considered statistically significant. RESULTS: Of the female participants, 20.4% had sexual dysfunction (SD). Longer duration of marriage (P = 0.045) and increase in the number of EPs (P < 0.001) were associated with a decrease in SF. A quarter of women experienced poor QMR. Increase in spouse age (P = 0.047), longer duration of marriage (P = 0.028), and increase in the number of EPs (P < 0.001) were associated with a decrease in QMR. There was a significant direct relationship between SF and the QMR (r = 0.857; P < 0.001). CONCLUSION: The present study showed a significant relationship between SF and the QMR in women with a history of EP. Therefore, SF and the QMR are necessary to be considered in future health promotion programs of these women.

BACKGROUND: Menopause is a natural period in women's life and can be affected by several factors. The aim of this study was to identify the associated factors for age of natural menopause and among women with early and premature menopause based on a cohort study in Iran. METHODS: This population-based study was conducted on 894 post menopause women between 35 and 70 years old who participated in the Bandare-Kong Non-Communicable Diseases (BKNCD) Cohort Study, a part of Prospective Epidemiological Research Studies in Iran (PERSIAN) from March 2016 to February 2019. All women completed a standard self-reported questionnaire. Data were analyzed using chi-square test, independent t test, and ANOVA as well as a multivariable linear regression model. RESULTS: The mean age at natural menopause was 48.31 ± 6.34 years. After adjusting other variables, gravida, history of cardiac disease, socioeconomic status and residence status were predictive of age at menopause (P < 0.001). Among the premature menopause group, the mean age at menopause was significantly higher among women with diabetes compared to women without diabetes group (35.68 ± 2.92 vs. 33.82 ± 3.06; P = 0.043), while the mean age at menopause was significantly lower in women with infertility compared to women without infertility (29.13 ± 5.22 vs. 34.84 ± 2.826; P = 0.048). CONCLUSIONS: This study suggests that the predictors of menopausal age differed in women with premature menopause compared to overall menopause age. Prospective studies are needed to evaluation the effects of these factors on menopausal age.
RESUMO
BACKGROUND: Self-medication is the use of unprescribed drugs to treat a disease. Elderly self-medication can be more dangerous compared to other age groups because of changes in organ functions that occur due to senescence. This study aimed to estimate the prevalence of self-medication in the elderly, its related factors, and common drugs used in this regard. MATERIALS AND METHODS: Electronic databases such as PubMed, Scopus, and Web of Science were searched between January 2016 and June 2021. The search strategy was built on two core concepts: "self-medication" and "aged". The search was limited to original articles in the English language. A random effect model was used to estimate the pooled prevalence of self-medication. Heterogeneity among studies was assessed using both the I2 statistic and the χ 2 test. Also, a meta-regression model was used to investigate the potential sources of heterogeneity of the studies. RESULTS: Out of 520 non-duplicate studies, 38 were included in the meta-analysis. Self-medication in the elderly ranged from 0.3% to 82%. The pooled proportion of self-medication was 36% (95% CI: 27%-45%). The result of the χ 2 test and the I2 index (P < 0.001, I2= 99.90%) revealed notable heterogeneity among the included studies in the meta-analysis. The meta-regression showed a significant association between the sample size (adjusted ß = -0.01; P = 0.043) and the pooled proportion of self-medication. CONCLUSION: The prevalence of self-medication in the elderly is high. Education through mass media to raise awareness about the dangers of self-medication can help solve this problem.
RESUMO
OBJECTIVES: This study aims to evaluate the effect of vitamin D and magnesium supplementation on clinical symptoms and serum inflammatory and oxidative stress markers in patients with COVID-19. TRIAL DESIGN: This study is a 4-arm randomized, double-blind, placebo-controlled clinical trial with a factorial design and the intervention period is 3 weeks. PARTICIPANTS: This study is conducted on COVID-19 patients admitted to the Shahid Mohammadi hospital in Bandar Abbas, Iran, who are eligible for inclusion in the study. Patients are included only if they meet all of the following criteria: (1) aged from 18 to 65 years old; (2) confirmation of COVID-19 by RT-PCR test; (3) completing informed consent; (4) passing less than 48 h since the patient's hospitalization; (5) no skin or gastrointestinal allergies due to taking multivitamin supplements, vitamin D, and magnesium; and (6) having more than 30 breaths per minute and less than 93% oxygen saturation in room air and sea level. Patients are excluded if they have any of the following conditions: (1) pregnancy or lactation; (2) taking a daily multivitamin or take a vitamin D or magnesium supplement in the last month; (3) participating in other clinical trials; (4) renal failure or dialysis, severe liver disease or cirrhosis; (5) known diagnosis of hypercalcemia; (6) discharging from the hospital less than 24 h after the start of the intervention; (7) history of kidney stones in the last year; (8) transfer the patient to the ICU; (9) baseline vitamin D levels above 80 ng/ml; (10) baseline magnesium levels above 2.6 mg/dl; and (11) unwillingness of the patient to continue the study. INTERVENTION AND COMPARATOR: Participants will be randomly allocated to one of the four following groups: (A) vitamin D (two 50,000 IU capsules at the beginning of the study, two 50,000 IU capsules on the 4th day, one 50,000 IU capsule on the 11th day, and one 50,000 IU capsule on the 17th day) and magnesium supplement (300 mg/day); (B) vitamin D capsule and magnesium placebo; (C) magnesium supplement and vitamin D placebo; and (D) vitamin D placebo and magnesium placebo. MAIN OUTCOMES: The resolution of clinical symptoms (fever, dry cough, shortness of breath, headache, myalgia, oxygen saturation, and mortality rate) and interpretation of laboratory assays (CRP, MDA, TAC, WBC, neutrophils count, lymphocytes count, ratio of neutrophils to lymphocytes, levels of 25 hydroxyvitamin D and magnesium) will be assessed in the study groups. RANDOMIZATION: A computer-generated block randomization list is used for randomization. BLINDING (MASKING): Investigators and patients are blinded to group allocation and treatment. A double-blind design is achieved using matched placebos. NUMBERS TO BE RANDOMIZED (SAMPLE SIZE): A total of 104 eligible patients are randomized into four groups of 26 subjects (1:1:1:1 allocation ratio). DISCUSSION: With the rapid prevalence of COVID-19 in recent years, more attention has been paid to effective dietary supplementation to improve clinical symptoms and biochemical parameters in these patients. To our knowledge, this is the first study to evaluate the effects of vitamin D supplementation in combination with magnesium or alone with respect to this infectious disease. The findings of the current RCT will provide evidence regarding the effectiveness of dietary supplementation strategies to improve COVID-19 outcomes.

BACKGROUND: Obesity is one of the major determinants of blood pressure. This study aimed to determine the optimal sex- and age-specific cut-off points of anthropometric indices, including body mass index (BMI), waist circumference (WC), hip circumference (HC), wrist circumference (WrC), waist-hip ratio (WHR), and waist-height ratio (WHtR), to screen for hypertension (HTN) in a cohort of Iranian adults aged 35 to 70 years, and to compare the predictive performance of the indices based on receiver operating characteristic (ROC) curves. METHODS: This population-based study was carried out on the participants aged 35 to 70 years of the Bandare-Kong Non-Communicable Diseases (BKNCD) Cohort Study, a part of the Prospective Epidemiological Research Studies in IrAN (PERSIAN). Using the area under the receiver operating characteristic curve (AUC) and Youden's J index, optimal sex- and age-specific cut-off points of the anthropometric indices in association with HTN were calculated. RESULTS: This study included a total of 2256 females and 1722 males. HTN was diagnosed in 736 females (32.6%) and 544 males (31.6%). The optimal cut-off of WC for HTN was 90 cm in males and 95 cm in females, with an area under the ROC curve (AUROC) of 0.60 and 0.64, respectively. For HC, the optimal cut-off was 95 cm for males and 108 cm for females (AUROC = 0.54 for both). Moreover, WrC optimal cut-offs were 17 cm for males (AUROC = 0.56) and 15 cm for females (AUROC = 0.57). As for BMI, the optimal cut-off was 25 kg/m2 in males and 27 kg/m2 in females (AUROC of 0.59 and 0.60, respectively). Also, a cut-off of 0.92 was optimal for WHR in males (AUROC = 0.64) and 0.96 in females (AUROC = 0.67). On the other hand, WHtR optimal cut-offs were 0.52 for males and 0.60 for females (AUROC of 0.63 and 0.65, respectively). CONCLUSIONS: WHR and WHtR, as anthropometric indices of obesity, were demonstrated to be significant predictors of HTN. Further, we suggest using WHR (cut-off point of 0.92 for males and 0.96 for females) and WHtR (cut-off point of 0.52 for males and 0.60 for females) as measures of preference to predict HTN among the southern Iranian population. Further multicenter longitudinal studies are recommended for a more accurate prediction of HTN.

Chronic non-communicable diseases (NCDs), are the leading causes of death among adults worldwide. It is projected that half of the NCDs could be avoided by preventing measures. Under the prospective epidemiological research studies in Iran (PERSIAN), we established a prospective population-based cohort study in southern Iran. The present study was designed to observe changing pattern of lifestyle transition over time and investigate the incidence and prevalence of regional modifiable risk factors as well as their associations with major NCDs. At baseline, 4063 participants aged 35-70 years were recruited on Oct, 2016and planned to get re-evaluated every 5 years along with annual follow-up. Data using validated electronic questionnaire comprising 55 questions and 482 items including general, medical and nutrition queries was collected. Blood, hair, nails, urine specimens and anthropometric measurements were taken. The response rate was 99%. In the results; male and female participants were 42.5% and 57.5%, respectively. Of note, 30.4% of women and 16.1% of men were obese. The prevalence of hypertension in men and women was 14.6% and 21%; however, diabetic men and women were 17.4% and 12.4%, respectively. Living in rural areas increased the odds of having hypertension by 1.33 (AOR = 1.33, 95% CI:1-09, 1.61). Noteworthy, logistic regression displayed that aging could predispose individuals to be more overweight, hypertensive and diabetic. The prevalence of multimorbidity of 3 or more NCDs were 8% (No. 326) and 6% (No.240), respectively. Intake of fruits, vegetables and dairy was less than two servings per day in 9.2%, 13% and 58.3% of the participants. Lower cardiovascular diseases and serum level of FBS and higher HDL level in sailors/fishermen compared to other job groups were significant (p-value <0.001). The second annual follow-up was completed and now at the end of the third wave. Findings of the present study signified the high prevalence of behavioral risk factors and their associations with respective NCDs. Subsequently, it is essential to keep track lifestyle variations, the modifiable risk factors and NCDs trends by prospective population-based cohort studies.

BACKGROUND: So far, no comprehensive studies have been performed to assess burden and determinants of anemia in Iran. In the present study, we aimed to answer this query using the data obtained from the Prospective Epidemiological Research Studies in IrAN (PERSIAN). METHODS: In this cross-sectional study, we included 161,686 adult participants (aged 35 years and older) from 16 provinces of Iran. Anemia was defined as a hemoglobin concentration of <13 g/dL in males and <12 g/dL in females. To evaluate the association between anemia and different factors, we used the multivariable Poisson regression analysis with robust variance by applying adjusted prevalence ratio (PR) with 95% confidence interval (CI). RESULTS: Of the total number of subjects, 72,387 (44.77%) were male and others were female. Mean age was 49.39±9.15 years old. The overall age- and sex-standardized prevalence of anemia was 8.83% (95% CI: 8.70-8.96%) in the included population. The highest and the lowest age- and sex-standardized prevalence of anemia pertained to Hormozgan (37.41%, 95% CI: 35.97-38.85%) and Kurdistan (4.57%, 95% CI: 3.87-5.27%) provinces, respectively. Being female (PR = 2.97), rural residence (PR = 1.24), being retired (PR = 1.53) and housewife (PR = 1.11), third and fourth wealth status quartiles (PR = 1.09 and PR = 1.11, respectively), being underweight (PR = 1.49), drug user (PR = 1.35), inadequate sleep (PR = 1.16), poor physical activity (PR = 1.15), diabetes (PR = 1.09), renal failure (PR = 2.24), and cancer (PR = 1.35) were associated with increased risk of anemia. On the other hand, illiteracy (PR = 0.79) and abdominal obesity (PR = 0.77) decreased the risk of anemia. CONCLUSIONS: According to the results, a variable prevalence of anemia was observed across the included provinces. We tried to provide an informative report on anemia prevalence for health professionals and authorities to take measures for identification and management of the cases of anemia in high-prevalence areas.

Background: The clinical characteristics of COVID-19 are diverse from a simple common cold symptom to acute respiratory distress syndrome (ARDS). In the present study, we attempted to identify the associated factors in surviving COVID-19 intensive care unit (ICU) patients based on their clinical characteristics. Materials and Methods: This retrospective study was performed on 114 laboratory-confirmed COVID-19 patients admitted to the intensive care units of Hormozgan University of Medical Sciences, Iran. Demographic, medical, clinical manifestations at admission time, and outcome data were obtained from the patient's medical records. Results: Of 114 participants included in this study, 64.9% were men. Their mean age was approximately 54 years old, 69.3% of them died and 30.7% of them were discharged. The mortality rate was 2.96 times higher in people who had ARDS compared to their counterparts, 1.37 times higher in people under non-invasive ventilation, and 3.56 times higher in people under invasive mechanical ventilation.Three common underlying diseases among them were hypertension in 34.2%, diabetes in 23.7%, and cardiovascular diseases in 17.5% of them. Alive and dead patients significantly differed only in the following laboratory tests: D-dimer, urea, troponin, Procalcitonin, and ferritin. Conclusion: The mortality rate among COVID-19 patients admitted to ICU is generally high. Dyspnea, as the initial presentation and comorbidity, especially hypertension, diabetes, and cardiovascular diseases, may be associated with a higher risk of developing severe disease and consequent mortality. Therefore, D-dimer, urea, troponin, Procalcitonin, and ferritin at the time of hospital admission could predict the severity of the disease and its probable mortality.
RESUMO
BACKGROUND: A variety of health problems, such as metabolic syndrome (MetS), have been linked to sleep disorders. While numerous epidemiological studies have shown a U-shaped relationship between sleep duration and poor health outcomes, the results were limited and inconsistent. This study was designed to evaluate the relationship between sleep duration and MetS. METHODS: This population-based study was conducted on the participants aged 35-70 of Bandare-Kong Non-Communicable Diseases (BKNCD) Cohort Study, a part of Prospective Epidemiological Research Studies in IrAN (PERSIAN). MetS was diagnosed according to the National Cholesterol Education Program (NCEP) criteria and the Iranian-specific cut-off for waist circumference (≥ 95 cm). Sleep information was extracted through a standard questionnaire based on self-reported information. Data were analyzed by R software using generalized additive models (GAMs). A statistically significant level was considered as P < 0.05. RESULTS: A total of 3695 participants were included in the analyses. The mean age was 48.05 years (SD 9.36), and 2067 (55.9%) were female. The estimated Prevalence of MetS was 35.9%, and women appeared to be more likely to have MetS than men (P < 0.001). There was a non-linear and linear association between sleep duration and the risk of MetS in women and men, respectively. The lowest risk was observed among those with 7-7.5 h of sleep duration per night. CONCLUSION: Long sleep duration was associated with increased risk of MetS and higher MetS severity score in both genders, while the short sleep duration increased the risk of Mets as well as MetS severity score just in women. The longitudinal studies would be suggested to assess the relationship between sleep quality and quantity components and MetS.
RESUMO
BACKGROUND: Nursing students experience a high level of stress in clinical settings. This study aimed to investigate the stress perceived by Iranian nursing students in the clinical learning environment and its relationship with the characteristics of students. METHODS: In this cross-sectional study, 430 nursing students who had passed at least 1 clinical training unit were recruited from universities in the Southeast of Iran using the census method. Data were collected by administering a demographic and researcher-made questionnaire to assess the perceived clinical stress. Demographic characteristics included age, sex, marital status, year of study, interest in the field, and previous semester average. Data were analyzed using independent t-test, ANOVA, and correlation coefficient test (α < 0.05). RESULTS: The mean score of overall stress experienced by the participants was 92.08±16.8 (out of 160), which was at a moderate level. Based on the study results, the most stress-inducing factors for students were instructors' limited clinical competence and instructors' inappropriate conduct. Gender (p = 0.01), fathers' education (p = 0.01), mothers' education (p = 0.01), interest in the field (p = 0.01), and year of study (p = 0.01) had a significant effect on the mean score of perceived clinical stress. CONCLUSION: The results of this study showed a moderate level of stress among the students. Also, instructors' limited clinical competence and inappropriate conduct were 2 factors that caused the highest perceived stress among nursing students more than other factors.
RESUMO
BACKGROUND: Breast cancer is a top biomedical research priority, and it is a major health problem. Therefore, the present study aimed to determine the prognostic factors of breast cancer survival using cure models. METHODS: In this retrospective cohort analytic study, data of 140 breast cancer patients were collected from Ali Ibn Abi Taleb hospital, Rafsanjan, Southeastern Iran. Since in this study, a part of the population had long-term survival, cure models were used and evaluated using DIC index. The data were analyzed using Openbugs Software. RESULTS: In this study, of 140 breast cancer patients, 23 (16.4%) cases died of breast cancer. Based on the findings, the Bayesian nonmixture cure model, with type I Dagum distribution, was the best fitted model. The variables of BMI, number of children, number of natural deliveries, tumor size, metastasis, consumption of canned food, tobacco use, and breastfeeding affected patients' survival based on type I Dagum distribution. CONCLUSION: The results of the present study demonstrated that the Bayesian nonmixture cure model, with type I Dagum distribution, can be a good model to determine factors affecting the survival of patients when there is the possibility of a fraction of cure. In this study, it was found that adapting a healthy lifestyle (eg, avoiding canned foods and smoking) can improve the survival of breast cancer patients.

BACKGROUND: Dialysis is a dominant therapeutic method in patients with chronic renal failure. The ratio of those who experienced the event to the predictor variables is expressed as event per variable (EPV). When EPV is low, one of the common techniques which may help to manage the problem is penalized Cox regression model (PCRM). The aim of this study was to determine the survival of dialysis patients using the PCRM in low-dimensional data with few events. STUDY DESIGN: A cross-sectional study. METHODS: Information of 252 dialysis patients of Bandar Abbas hospitals, southern Iran, from 2010-16 were used. To deal with few mortality cases in the sample, the PCRM (lasso, ridge and elastic net, adaptive lasso) were applied. Models were compared in terms of calibration and discrimination. RESULTS: Thirty-five (13.9%) mortality cases were observed. Dialysis data simulations revealed that the lasso had higher prediction accuracy than other models. For one unit of increase in the level of education, the risk of mortality was reduced by 0.32 (HR=0.68). The risk of mortality was 0.26 (HR=1.26) higher for the unemployed than the employed cases. Other significant factors were the duration of each dialysis session, number of dialysis sessions per week and age of dialysis onset (HR=0.93, 0.95 and 1.33). CONCLUSION: The performance of penalized models, especially the lasso, was satisfying in low-dimensional data with low EPV based on dialysis data simulation and real data, therefore these models are the good choice for managing of this type of data.
