The association between self-efficacy, perceived social support, and family resilience in patients undergoing hemodialysis: a cross-sectional study.

BACKGROUND: Self-efficacy of patients on hemodialysis is considered a main component of the successful management of chronic kidney diseases. The self-efficacy of these patients may be influenced by many individual and social factors. This study aimed to assess the association between perceived self-efficacy and social support by patients on hemodialysis treatment and the resilience of their families. METHODS: This cross-sectional study was conducted on 183 patients and 183 families of hemodialysis patients in the largest hemodialysis center in northwest of Iran. Data was collected from July to December 2021 using chronic kidney disease self-efficacy, multidimensional perceived social support (MSPSS), and the Walsh family resilience questionnaire (WFRQ). The collected data were analyzed by SPSS software using descriptive and inferential statistical tests. RESULTS: The findings showed that the mean score of patients' self-efficacy was 171.63 ± 38.19 in a possible range of 25 to 250. Moreover, the mean score of perceived social support was 62.12 ± 16.12 in a possible range of 7 to 84. The mean total score of family resilience was 119.08 ± 26.20 in a possible range of 32 to 84. Also, the results of the study showed a positive and significant relationship between the self-efficacy of patients with their perceived social support and the resilience of their families (p < 0.01). CONCLUSION: The results of the study showed that there is a significant relationship between patient self-efficacy and family resilience and social support received in chronic kidney patients undergoing hemodialysis. Therefore, it is suggested to consider practical strategies in the field of family resilience and social support to improve patients' self-efficacy.

Relationship between resilience and self-efficacy among Iranian nurses: a cross-sectional study during the post-Corona era.

BACKGROUND: Resilience and self-efficacy play an influential role in nurses' clinical performance, which are considered resources for improving adaptability and promoting work engagement. This study aimed to determine the relationship between resilience and self-efficacy among nurses at Shahroud University of Medical Sciences hospitals during the post-Corona era. METHODS: This cross-sectional study was conducted on 280 nurses in all clinical departments. Nurses with a bachelor of science in nursing or higher degree and at least one year of full-time work experience were included in the study using a convenience sampling method. Participants completed a three-part tool, which included the demographic information form, the Connor-Davidson Resilience Scale, and the General Self-Efficacy Scale. The data were analyzed using descriptive statistics and inferential tests (multivariate linear regression using the backward method). RESULTS: In this study, nurses reported low levels of resilience (63.64 ± 15.66) and high levels of self-efficacy (63.01 ± 9.57). Among the five resilience subscales, the highest mean item score was associated with "spiritual influences" (2.80 out of 4), while the lowest mean item score was associated with "trust in one's instincts and tolerance of negative affect" (2.36 out of 4). Furthermore, the multivariate linear regression model results indicated that self-efficacy accounted for 33.6% of the variance in resilience (P < 0.001 and ß = 0.952). CONCLUSION: According to the results of the present study, it is suggested that nurses' psychological capabilities, such as self-efficacy, should be increased to improve resilience and address the stressful conditions of the work environment.

Comparison of barriers to effective nurse-patient communication in COVID-19 and non-COVID-19 wards.

BACKGROUND: Communication is a basic need of humans. Identifying factors that prevent effective nurse-patient communication allows for the better implementation of necessary measures to modify barriers. This study aims to compare the barriers to effective nurse-patient communication from the perspectives of nurses and patients in COVID-19 and non-COVID-19 wards. MATERIALS AND METHODS: This cross-sectional descriptive study was conducted in 2022. The participants included 200 nurses (by stratified sampling method) and 200 patients (by systematic random sampling) referred to two conveniently selected hospitals in Shahroud, Iran. The inclusion criteria for nurses were considered having at least a bachelor's degree and a minimum literacy level for patients to complete the questionnaires. Data were collected by the demographic information form and questionnaire with 30 and 15 questions for nurses and patients, which contained similar questions to those for nurses, based on a 5-point Likert scale. Data were analysis using descriptive indices and inferential statistics (Linear regression) in SPSS software version 18. RESULTS: The high workload of nursing, excessive expectations of patients, and the difficulty of nursing work were identified by nurses as the main communication barriers. From the patients' viewpoints, the aggressiveness of nurses, the lack of facilities (welfare treatment), and the unsanitary conditions of their rooms were the main communication barriers. The regression model revealed that the mean score of barriers to communication among nurses would decrease to 0.48 for each unit of age increase. Additionally, the patient's residence explained 2.3% of the nurses' barriers to communication, meaning that native participants obtained a mean score of 2.83 units less than non-native nurses, and there was no statistically significant difference between the COVID and non-COVID wards. CONCLUSION: In this study, the domain of job characteristics was identified by nurses as the major barrier, and patients emphasized factors that were in the domain of individual/social factors. There is a pressing need to pay attention to these barriers to eliminate them through necessary measures by nursing administrators.

Inhibitors and facilitators of compliance with professional ethics standards: nurses' perspective.

INTRODUCTION: The clinical practices of nurses should be in accordance with the principles of professional ethics. Respecting professional ethics principles depends on several factors. The present study was conducted to investigate the effective inhibitors and facilitators in compliance with professional ethics and their importance from the nurses' perspective. METHODS: During this cross-sectional descriptive study, 452 nurses were included by the census sampling method. The data were collected via the "inhibitors of compliance with professional ethics standards by the nurses' perspective" and "facilitators of compliance with professional ethics standards by the nurses' perspective" questionnaires. Additionally, by designing the "open-ended question" section, other inhibiting and facilitating factors of professional ethics standards from the nurses' perspective were investigated. The data were analyzed using descriptive and inferential statistics (Wilcoxon signed ranks test). RESULTS: The individual care-related dimension as a facilitator had the highest mean score compared to the other dimensions (76.62 ± 4.92). Furthermore, seven items in the inhibitor section, 19 items in the facilitator section had higher scores. Among them, there were seven items in common. Strong or weak belief in compliance with ethical issues had the highest mean scores in the role of facilitator and inhibitor (90.54 ± 12.13 and 89.54 ± 14.88, respectively). CONCLUSION: Strong or weak belief in compliance with ethical issues was the most important inhibitor and facilitator from the nurses' perspective, which makes it necessary to examine individual beliefs about ethical issues among applicants to enter the nursing profession.

Psychometric evaluation of the Persian version of the Sense of Belonging in Nursing School (SBNS): a quantitative and cross-sectional design.

BACKGROUND: This study aimed to evaluate the psychometric indicators of the Persian version of the Sense of Belonging in Nursing School scale (SBNS). METHODS: The study conducted in Shahroud and Semnan schools of nursing and midwifery in Iran examined nursing students using a cross-sectional approach by convenience sampling method from 3/6/2023 to 24/8/2023. To assess the SBNS scale, the forward-backward procedure was used to translate it into Persian. Face and content validity were evaluated, and exploratory and confirmatory factor analyses were conducted with sample sizes of 200 and 182, respectively. Reliability was assessed using Cronbach's alpha coefficient, MacDonald's omega, and intra-class correlation coefficient. RESULTS: The exploratory factor analysis resulted in the exclusion of four items, leaving a final selection of 15 items. These items were categorized into three factors: classmates, clinical staff, and inclusive educational environment, which accounted for 49.16% of the overall variance. The confirmatory factor analysis indicated that the model was a good fit for the observed data, and the subscales had high internal consistency (Cronbach's alpha coefficient was 0.752 to 0.880) and stability (intra-class correlation coefficient was 0.889 to 0.968). CONCLUSION: According to the results, it can be concluded that the Persian version of the SBNS scale demonstrates sufficient validity and reliability in assessing students' sense of belonging to the nursing school.

Barriers to maintaining dignity for patients with schizophrenia: A qualitative study.

BACKGROUND: Since dignity is one of the fundamental rights of each patient, maintaining patients' dignity is essential. Unfortunately, in many cases, particularly among patients with schizophrenia (SCZ), dignity is not fully respected. Nonetheless, there is limited knowledge regarding this matter in Middle Eastern Nations. RESEARCH OBJECTIVE: This study aimed to identify the barriers to maintaining dignity for patients with schizophrenia from the perspective of patients with schizophrenia, their family caregivers, and healthcare personnel. RESEARCH DESIGN: This qualitative study was conducted with patients (n = 16), family caregivers (n = 4), and healthcare personnel (n = 6) who were selected using a purposeful sampling method. The data were collected through semi-structured, in-depth face-to-face interviews until the data reached saturation. Data were analyzed using the Graneheim and Lundman method. ETHICAL CONSIDERATIONS: The Research Ethics Committee of Urmia University of Medical Sciences (IR.UMSU.REC.1401.099). FINDINGS: Analysis of the interviews revealed two main themes and five subthemes as the barriers to maintaining dignity for patients with schizophrenia. The main themes included "Black shadow of stigma" (three subthemes: "Facing the fear and discrimination of others," "Misconceptions in society," and "Social rejection") and "Facing violations" (two subthemes: "Basic human rights violation" and "Negative emotional responses"). CONCLUSION: Patients' dignity with schizophrenia was at a low level due to the negative attitude of society toward these patients. In this respect, the basic human rights violations, social rejection, and misconceptions were abundant in society and care centers. An in-depth comprehension of the threatening factors affecting dignity can assist policymakers in safeguarding their dignity through effective programs.

Organizational silence and hidden threats to patients' dignity with schizophrenia: A qualitative study.

BACKGROUND: Maintaining patients' dignity is a key ethical requirement in healthcare and is emphasized in nursing standards. This issue is particularly significant for patients with schizophrenia because they face unique challenges such as physical and psychological difficulties, dependence on others, and social isolation, making them more vulnerable. Organizational factors can either threaten or preserve their dignity. However, there is little knowledge in this domain within the sociocultural context of Iran. RESEARCH OBJECTIVE: This study aimed to explore the role of the healthcare organization in the dignity of patients with schizophrenia, based on the opinions of patients, healthcare personnel, and family caregivers. RESEARCH DESIGN: This qualitative study was conducted with 26 participants (16 patients, 4 family caregivers, 2 nurses, 3 psychologists, and 1 service worker) who were selected using a purposeful sampling method. The data were collected through semi-structured, in-depth face-to-face interviews until data saturation was reached. The data were analyzed via Graneheim and Lundman's method. ETHICAL CONSIDERATIONS: The study protocol was approved by the Research Ethics Committee of Urmia University of Medical Sciences (IR.UMSU.REC.1401.099). FINDINGS: Based on data analysis, participants reported the three following challenges as organizational hidden threats to patients' dignity: "Lack of facilities," "premature management," and "ineffective communication." CONCLUSION: The study findings indicated that the healthcare organization does not support the dignity of patients. Management inefficiency and lack of facilities are evident in psychiatric hospitals, and healthcare centers are not monitored based on standard criteria. Limited interactions between healthcare personnel and patients were identified as the main reasons for the neglect of patients with schizophrenia and the violation of their dignity. The results of this study can help healthcare policymakers in designing and implementing effective programs to preserve the dignity of patients with schizophrenia.

Psychometric Properties of the Revised Version of the Prolonged Grief Disorder Scale (PG-13-R): A Methodological Study in the Iranian Population.

Prolonged grief disorder has recently been officially introduced as a new mental disorder. This study aimed to validate the Persian version of the revised Prolonged Grief Scale (PG-13-R). This study was conducted among the general population in Shahroud, Iran, during 2023. Employing face and content validity, along with exploratory and confirmatory factor analyses (EFA), the study validates the PG-13-R. Average variance extracted value showed an acceptable convergent validity. The EFA reveals a singular factor structure explaining 60.541% of the variance in prolonged grief disorder, and the confirmatory factor analysis demonstrates an excellent model fit. Internal consistency, evaluated through Cronbach's alpha and MacDonald's omega, highlights the scale's reliability. The Persian version of PG-13-R had acceptable composite reliability. Stability is confirmed by an intra-class correlation coefficient. In conclusion, the Persian PG-13-R displays satisfactory validity and reliability to assessing prolonged grief symptoms in the Iranian population.

Prevalence of uncontrolled hypertension and its associated factors in 50-74 years old Iranian adults: a population-based study.

BACKGROUND: By the lengthening of life span, the incidence of chronic diseases such as hypertension and uncontrolled hypertension has increased. This study aims to determine the prevalence of uncontrolled hypertension and its related factors in the age group of 50-74 years in Shahroud, northeast Iran. METHODS: The data of the third phase of the Shahroud Eye Cohort Study were used in this study. This phase of the cohort study included 4394 participants aged 50 to 74 years from the previous phases. In addition to ophthalmological and optometric examinations, demographic characteristics, blood biochemistry tests, and blood pressure measurements were performed in this phase. Individuals with a blood pressure ≥ 140/90 mm/Hg (being treated or not treated with antihypertensive medicines) were defined as uncontrolled hypertension. In patients with diabetes and chronic kidney disease, blood pressure equal to or higher than 130/80 mm/Hg was considered uncontrolled hypertension. Descriptive statistics and multiple logistic regression were used to analyze the data. FINDINGS: Overall, the prevalence of uncontrolled hypertension out of all the participants was 61.7% (95% CI: 60.3-63.2). Multiple regression results showed that the male gender (OR: 2.1, 95% CI: 1.5-2.9), patients with diabetes (OR:3.2, 95% CI: 2.4-4.3), and patients with chronic kidney disease (CKD) (OR: 3.2, 95% CI: 2.5-4.1) increased the risk of uncontrolled hypertension while in patients with cardiovascular disease (OR: 0.6, 95% CI: 0.4-0.8) and polypharmacy (OR: 0.2, 95% CI: 0.1-0.2) reduced the risk of uncontrolled hypertension. CONCLUSION: The present study showed that uncontrolled hypertension has a high prevalence, and factors such as male gender, diabetes, and CKD are associated with this disorder. So, it is recommended to take the necessary measures to formulate and implement immediate actions to prevent or control hypertension.

Comparison of the effect of pressure control and volume control ventilation on endotracheal tube cuff pressure in patients undergoing general anesthesia and mechanical ventilation: a parallel randomized clinical trial.

BACKGROUND: Endotracheal intubation and mechanical ventilation are prevalent interventions in the operating room and intensive care unit. Recently, the complications of endotracheal tube cuff pressure have been a topic of interest. Therefore, this study compared the effect of pressure control and volume control ventilation modes on the endotracheal cuff pressure rate in patients undergoing general anesthesia and mechanical ventilation. METHODS: In this triple-blinded randomized clinical trial, 50 patients undergoing open limb surgery and inguinal hernia were allocated to two groups of 25 based on inclusion criteria. After intubation, one group underwent ventilation on the pressure control ventilation mode, and the other underwent ventilation on the volume control ventilation mode. In both groups, using a manometer, the cuff's pressure was first adjusted in the range of 25-30 cm of water. Then, the cuff pressure was measured at 10, 20, and 30 min intervals. The data were statistically analyzed using independent t-test, and two-way repeated measures ANOVA. RESULTS: The present study's findings showed that cuff pressure has significantly decreased over time in both study groups (F = 117.7, P < 0.001). However, a repeated measures ANOVA with a Greenhouse-Geisser correction showed no interaction between time and groups (F = 0.019, P = 0.98). The two groups had no significant difference in cuff pressure (F = 0.56, P = 0.458). CONCLUSION: Since the cuff pressure has been significantly reduced in both groups over time, continuous monitoring of endotracheal tube cuff pressure in patients undergoing mechanical ventilation is essential. Therefore, it is suggested to keep the cuff pressure within the recommended range to prevent complications resulting from cuff pressure reduction, such as aspiration and ventilation decrease. TRIAL REGISTRATION: The study was registered in the Iranian Registry of Clinical Trial on 23/02/2019 (trial registration number: IRCT20181018041376N1).

Relationship between academic success, distance education learning environments, and its related factors among medical sciences students: a cross-sectional study.

BACKGROUND: Academic success is among the most important criteria for determining students' competence. Hence, one of the concerns of education system researchers has always been investigating its associated factors. Therefore, this study aimed to determine the relationship between academic success, distance education learning environments, and its related factors among Shahroud University of Medical Sciences students. METHODS: This cross-sectional study was conducted on 208 medical sciences students who completed at least two online and two in-person academic semesters. Participants were selected through the convenience sampling method and filled out three questionnaires, including the demographic information form, the Academic Success Inventory for College Students, and the Distance Education Learning Environments Survey. Finally, the data were analyzed using descriptive statistics and inferential tests (t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression). RESULTS: In this study, students reported moderate levels of academic success (107.81 ± 10.72). Moreover, they assessed their distance education learning environment as the positive points were more than the negative points (74.10 ± 14.89). Distance education learning environment (ß = 0.233 and P < 0.001) and field satisfaction (ß = 9.797 and P = 0.001) were also mentioned as factors related to students' academic success. CONCLUSION: According to the present results, it is suggested to improve the learning environment of distance education and increase students' satisfaction to enhance their academic outcomes such as academic success.

Reasons for resistance to change in nursing: an integrative review.

BACKGROUND: Change is a very complex and multifaceted phenomenon that is intertwined with the understanding of nursing practice, so, resistance to change in nursing can be considered as an important challenge. Knowing the reasons for this resistance can help in solving it in nursing. Therefore, the present study was conducted with the aim of investigating the reasons for resistance to change in nursing as an integrated review. METHODS: This integrative review was conducted using the Whittemore & Knafl method in 5 stages, including problem identification, searching the literature, evaluating primary sources, analyzing data, and presenting the results. Databases like SID, Irandoc, Magiran, Google Scholar, Web of Science, PubMed, CINAHL, and Scopus were searched using the keywords; "Resistance", "Change", "Nursing", "Resistance to Change" and their Persian equivalents in the time range of 2000 to January 2023. After applying inclusion criteria and assessing the articles using Bowling's Quality Assessment Tool, finally, 15 papers were included from 2964. RESULTS: After reviewing and critically appraisal of the qualified articles, the findings were placed in three main categories including; (1) individual factors, (2) interpersonal factors, and (3) organizational factors and six subcategories. CONCLUSION: Undoubtedly, change is an integral component in nursing care, and resistance to it is the result of a set of individual, interpersonal and organizational factors that change managers should pay special attention to in order to make changes due to the reasons of this resistance, and the development process of developing changes in the clinical field is easily possible.

Spiritual Well-Being and Death Anxiety: A Cross-Sectional Study Among Iranian Patients With Acute Coronary Syndrome.

Acute coronary syndrome (ACS) patients experience a tremendous psychological burden, typically in the form of death worry due to acute medical conditions and the possibility of mortality. The unfavourable conditions of ACS patients cause them to reconsider the meaning of life and their spiritual well-being. This study evaluated the association between death anxiety and spiritual well-being in a total of 241 ACS patients in Shahroud, northeast of Iran. The data were collected using the Templer Death Anxiety Scale, and the Spiritual Well-being Scale by convenience sampling method. All patients indicated a high degree of death anxiety, and roughly half reported a moderate level of spiritual well-being. There was a significant and direct correlation between death anxiety and spiritual well-being levels. Older age, single status, and non-smoking were other predictors of good spiritual well-being. A multidisciplinary health team should identify and implement approaches to promote spiritual well-being and reduce mental suffering.

Isolated systolic hypertension and its associated risk factors in Iranian middle age and older population: a population-based study.

BACKGROUND: Isolated systolic hypertension (ISH), is the most common form of hypertension in older adults. However, the ISH prevalence is not well known in many developing countries such as Iran. This study was conducted to determine the ISH prevalence and its related risk factors in an Iranian population. METHODS: Data were obtained from the second phase of the Shahroud eye cohort study (ShECS) in 2014. ShECS is a longitudinal population-based study which the first phase had been conducted in 2009 using the stratified multistage cluster sampling design on 5190 people aged 40 to 70 years. The ISH prevalence was determined based on the eighth Joint National Commission guidelines for different demographic variables. The associated risk factors were estimated by multiple logistic regression and a two-tailed p-value less than 0.05 was considered significant. RESULTS: The ISH prevalence was 15.89% (95% CI: 14.88-16.96). It was 15.68% (14.12-17.39) and 15.87% (14.54-17.29) for men and women, respectively. The prevalence of ISH increased significantly with increasing age. The 65-70 compared to 45-69 year age group (OR = 4.21), body mass index (OR = 1.03), diabetes (OR = 1.64), retirement, compared to practitioner job (OR = 1.53), and waist to hip ratio (WHR) (OR = 9.81) were significantly associated with ISH prevalence. CONCLUSIONS: ISH is highly prevalent among the older adult population in Iran. Given the risk of cardiovascular disease associated with ISH, it is recommended to conduct education and public health interventions to improve the detection, prevention, and treatment of ISH.

Ability of older adults to recognize cognitive changes and its relationship with mental health: a cross-sectional study.

INTRODUCTION: With rising age, the incidence of physical and mental problems increases. Physiological and social changes occur across the lifespan that can affect an individual's health and ability. The present study was aimed to determine older adult's ability to recognize cognitive changes and its relation with mental health status. MATERIALS AND METHODS: A descriptive correlational design was used to recruit 423 older adults who were referred to health centers in Tabriz, Iran in 2019 to receive primary health care. A systematic random sampling method was used for selecting participants. Data collection tools included a demographic-social questionnaire, General Health Questionnaire for assessing mental health (with 4 subscales) and a questionnaire of ability to recognize cognitive changes (with 8 sub-scales). Data were analyzed using descriptive statistics and inferential statistics. RESULTS: The mean score of mental health of the older adults was 56.35 (8.40) which shows moderately impaired mental health. The most impaired aspect of mental health detected was the social function dimension 13.20 (2.67). The average of the total ability score was 41.19 (4.78) and the physical strength dimension had the highest average of 9.08 (1.80) and the empowerment obligation dimension had the lowest average of 3.06 (1.08). There was significant relationship between dimensions of depression (r = 0.21, p < 0.001), anxiety (r = 0.1, p = 0.04) and social functioning (r = 0.17), p < 0.001) with the ability to recognize cognitive changes of the older adults. CONCLUSION: Negative mood states and social functioning were associated with the ability to recognize cognitive changes in this population of older adults. This sample exhibited moderately impaired mental health status and relatively large burdens of untreated affective symptoms. Although causality cannot be determined with this cross-sectional design, use of social programs to keep older adults mentally active, as well as cognitive rehabilitation programs could be tested with longitudinal designs for their impact on cognitive change recognition.

Health Care Providers' Attitudes Toward Do-Not-Resuscitate Order in COVID-19 Patients: An Ethical Dilemma in Iran.

This study aimed to investigate the health care providers' attitudes toward the Do-Not-Resuscitate order (DNR) in COVID-19 patients. This study was conducted on 332 health care providers (HCPs) at the COVID-19 referral hospital in Shahroud, Iran by convenience sampling method. The study tools included a demographic information form and the DNR attitude questionnaire. Significance level was considered 0.05 for all tests. The mean scores of attitudes toward DNR order, the procedure of DNR, some aspects of passive euthanasia, and religious and cultural factors were 25.27 ± 2.78, 40.61 ± 5.99, 11.26 ± 2.51, and 6.12 ± 1.27, respectively. The death of relatives due to COVID-19 and female gender were associated with high and low scores of attitudes toward DNR order, respectively. Extended working hours and more work experience were correlated with high scores of DNR procedure. The history of COVID-19 increased the mean score of attitudes toward some aspects of passive euthanasia. In addition, an increase in following COVID-19 news decreased the score of religious and cultural factors affecting DNR order. Despite the legal ban on implementation of the DNR in Iran, the attitude of Iranian HCPs toward this was positive in COVID-19 patients.

Salt intake and blood pressure in Iranian children and adolescents: a population-based study.

BACKGROUND: Previous studies have reported a high prevalence of hypertension in Iranian students, especially in rural areas. The aim of this study was to investigate the daily intake of salt in students and its association with high blood pressure. METHODS: A random sub-sample was selected from the participants of the second phase of Shahroud schoolchildren eye cohort study and then a random urine sample was tested for sodium, potassium and creatinine. Urine electrolyte esexcretion and daily salt intake were calculated by Tanaka et al.'s formula. RESULTS: Among 1455 participants (including 230 participants from rural area and 472 girls), the mean age was 12.9 ± 1.7 year and the mean daily salt intake was 9.7 ± 2.6 g (95% CI 9.5-9.8). The mean salt consumption in rural areas [10.8 (95% CI 10.4-11.2)] was higher than urban areas [9.4 (95% CI 9.3-9.6)], in people with hypertension [10.8 (95% CI 10.3-11.3)] was more than people with normal blood pressure [9.4 (95% CI 9.3-9.6)], and in boys [9.8 (95% CI 9.7-10.0)] was more than girls [9.3 (95% CI 9.1-9.6)]. Higher age, BMI z-score, male sex and rural life, were associated with increased daily salt intake. Increased salt intake was associated with increased systolic and diastolic blood pressure. CONCLUSION: Daily salt intake in Iranian adolescents was about 2 times the recommended amount of the World Health Organization, was higher in rural areas and was associated with blood pressure. Reducing salt intake should be considered as an important intervention, especially in rural areas.

High-speed microjets issue from bursting oil gland reservoirs of citrus fruit.

The rupture of oil gland reservoirs housed near the outer surface of the citrus exocarp is a common experience to the discerning citrus consumer and bartenders the world over. These reservoirs often rupture outwardly in response to bending the peel, which compresses the soft material surrounding the reservoirs, the albedo, increasing fluid pressure in the reservoir. Ultimately, fluid pressure exceeds the failure strength of the outermost membrane, the flavedo. The ensuing high-velocity discharge of oil and exhaustive emptying of oil gland reservoirs creates a method for jetting small quantities of the aromatic oil. We compare this jetting behavior across five citrus hybrids through high-speed videography. The jetting oil undergoes an extreme acceleration to reach velocities in excess of 10 m/s. Through material characterization and finite element simulations, we rationalize the combination of tuned material properties and geometries enabling the internal reservoir pressures that produce explosive dispersal, finding the composite structure of the citrus peel is critical for microjet production.

Validation of the Persian version of the comprehensive frailty assessment instrument plus in community-dwelling older adults.

This study aimed to examine the validity and reliability of the Persian Version of the Comprehensive Frailty Assessment Instrument Plus (CFAI-Plus) among community-dwelling older adults. It was completed by 340 older adults ≥60 years. The content and face validity were confirmed based on the opinion of the target group and experts. In the exploratory factor analysis, seven factors were extracted, explaining 62.8% of the total variance. Confirmatory factor analysis showed acceptable fit indices (Root Mean Square Error of Approximation = 0.045; Comparative Fit Index = 0.93; Tucker-Lewis Index = 0.92). Internal consistency was adequate for factors (Cronbach's alpha: range 0.47 to 0.88), and the test-retest reliability was acceptable (intra-class correlation coefficient: range 0.76 to 0.92). A higher CFAI-Plus score were found in those who were older, female, less-educated, single, lived alone, and had inadequate income. This study supports the reliability and validity of the Persian CFAI-Plus in community-dwelling older adults.

Influences of Occupational Burnout and Personality on Lipid Peroxidation Among Nurses in Shahroud City, Iran.

Considering the relationship between occupational burnout and oxidative stress, identifying the factors that affect occupational burnout, such as recognizing individual characteristics, would be beneficial for implementing strategies to reduce oxidative stress levels. This study was conducted on 92 nurses from a hospital in Shahroud, a city in northeastern Iran, who were chosen at random. The data was collected through the Demographic Questionnaire, Maslach Burnout Inventory and Personality Factors Inventory. Each participant's serum markers of oxidative stress were also measured. Total antioxidant capacity (TAC) and neuroticism were found to have a negative relationship in this study. Furthermore, marital status, the ward where nurses work, the type of contract, emotional exhaustion, and depersonalization were all found to be significant predictors of malondialdehyde (MDA). Neuroticism, emotional exhaustion, and depersonalization were the most important predictors of oxidative stress levels.The results of this study suggest that some approaches to reducing oxidative stress can be implemented by identifying the factors influencing occupational burnout and also by recognizing individuals' personality traits.
