Diagnostic accuracy of artificial intelligence models in detecting osteoporosis using dental images: a systematic review and meta-analysis.

The current study aimed to systematically review the literature on the accuracy of artificial intelligence (AI) models for osteoporosis (OP) diagnosis using dental images. A thorough literature search was executed in October 2022 and updated in November 2023 across multiple databases, including PubMed, Scopus, Web of Science, and Google Scholar. The research targeted studies using AI models for OP diagnosis from dental radiographs. The main outcomes were the sensitivity and specificity of AI models regarding OP diagnosis. The "meta" package from the R Foundation was selected for statistical analysis. A random-effects model, along with 95% confidence intervals, was utilized to estimate pooled values. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool was employed for risk of bias and applicability assessment. Among 640 records, 22 studies were included in the qualitative analysis and 12 in the meta-analysis. The overall sensitivity for AI-assisted OP diagnosis was 0.85 (95% CI, 0.70-0.93), while the pooled specificity equaled 0.95 (95% CI, 0.91-0.97). Conventional algorithms led to a pooled sensitivity of 0.82 (95% CI, 0.57-0.94) and a pooled specificity of 0.96 (95% CI, 0.93-0.97). Deep convolutional neural networks exhibited a pooled sensitivity of 0.87 (95% CI, 0.68-0.95) and a pooled specificity of 0.92 (95% CI, 0.83-0.96). This systematic review corroborates the accuracy of AI in OP diagnosis using dental images. Future research should expand sample sizes in test and training datasets and standardize imaging techniques to establish the reliability of AI-assisted methods in OP diagnosis through dental images.

Lead poisoning as a differential diagnosis in pediatric patients with chronic abdominal pain: a case-control study in Tehran-Iran.

BACKGROUND: Chronic abdominal pain is a potential symptom of lead poisoning, which is often challenging to diagnose. This case-control study aimed to evaluate blood lead levels in pediatric patients with chronic abdominal pain. METHODS: The case-control study was conducted on 190 pediatrics who presented to the Children's Medical Center Hospital clinics, Tehran between April 2021- 2023. The children were divided into two groups: the case group, consisting of 81 patients with chronic abdominal pain, and the matched control group; 109 children without any gastrointestinal symptoms. The statistical analysis of the data was performed using STATA 16. A multiple logistic regression model was used to assess the association of different independent variables with chronic abdominal pain. RESULTS: There was no significant difference between mean (± standard deviation [SD]) of age (8.80(2.7) years vs. control group: 9.23(3.9) years), sex, and BMI (16.55(4.6) vs. 17.32(4.7)) of the patients with chronic abdominal pain (case group) and the control group, whereas the mean weight was remarkably low in patients with chronic abdominal pain: 27.25(± 12.1) kg vs. 31.70(± 14.7) kg (P value = 0.028). Fifty-nine percent of children with chronic abdominal pain had serum lead levels ≥ 10 µg/dL. The mean (SD) of blood lead levels was statistically high in the case group: 11.09 (± 5.35) µg/dL vs. control group: 8.26 (± 5.01) µg/dL) (P value ≤ 0.05). The appetite level was significantly low in the case group: 3.8 (± 2.5) vs. control group 5.4 (± 1.3). CONCLUSIONS: Lead poisoning could be a possible cause of children's chronic abdominal pain. Regarding the high rate of lead poisoning in children exerting appropriate measures to reduce their exposure to lead is necessary.

Evaluation of the prevalence of cardiometabolic disorders (diabetes, hypertension, and hyperlipidemia) diagnosed, undiagnosed, treated, and treatment goal in the elderly: Bushehr Elderly Health Program (BEH).

As the population ages, the global burden of cardiometabolic disorders will increase. This study aimed to investigate the prevalence of cardiometabolic disorders (diabetes, hypertension, and hyperlipidemia) in elderly and to evaluate the effects of various variables including age, sex, education, marital status, smoking, income, physical activity, dementia and depressed mood on untreated cardiometabolic disorders. This was a cross sectional study conducted in Bushehr Elderly Health Program. A total 2381 participants were included. Medical data were collected by trained interviewers. The mean age of the study participants was 69.34 years. Proportions of diabetes, hypertension, hyperlipidemia and hypercholesterolemia were 43.25%, 75.71%, 64.74% and 35.31% respectively. Untreated diabetes prevalence was higher for males (OR = 1.60, 95%CI = 1.20-2.15), older adults (OR = 1.02, 95%CI = 1.00-1.05), and pre-frail status (OR = 0.69, 95%CI = 0.52-0.92). Males (OR = 2.16, 95%CI = 1.64-2.84) and current smokers (OR = 1.42, 95%CI = 1.05-1.93), in contrast to married participants (OR = 0.25, 95%CI = 0.08-0.78), people with higher education levels (OR = 0.51, 95%CI = 0.29-0.89) and dementia (OR = 0.78, 95%CI = 0.61-1.00) were more likely to have untreated HTN. Untreated dyslipidemia is more common in smokers (OR = 1.78, 95%CI = 1.19-2.66) and males (OR = 1.66, 95%CI = 1.21-2.27), while untreated hypercholesteremia is more common in males (OR = 3.20, 95%CI = 1.53-6.69) and is reported lower in people with dementia (OR = 0.53, 95%CI = 0.28-1.01).

The association of depressive symptoms with handgrip strength and gait speed in community-dwelling older adults: data from the baseline phase of Birjand Longitudinal Aging Study.

BACKGROUND: Depression is a multifaceted condition with a high prevalence and burden to society. Handgrip strength (HGS) and gait speed (GS) are indices of physical health, which is linked to mental health. Previous studies have shown heterogeneity among countries in the association of physical parameters and depression. In this study, we aimed to investigate the association of HGS and GS with depressive symptoms in older adults. METHODS: This is a cross-sectional study analyzing data from the Birjand Longitudinal Aging Study, a cohort of community-dwelling older adults (≥ 60 years old). Depressive symptoms were assessed by the nine-item Patient Health Questionnaire. HGS was measured with a hand dynamometer in a sitting position, and GS was estimated by a 15-foot walk test at usual pace. RESULTS: Compared to participants in the first quartile, those in the second quartile of HGS had significantly lower odds of suffering from depressive symptoms, while GS was not significantly associated with depressive symptoms. A higher HGS was associated with a lower risk of moderate depressive symptoms, while a higher GS was related to a lower risk of moderately severe and severe symptoms. CONCLUSIONS: Our findings suggest that older people residing in Birjand, Iran with a moderate HGS are less likely to suffer from depressive symptoms than those with lower HGS.

The relationship between internet addiction, sleep quality, and psycho-social problems among secondary school students in Erbil, 2023-2024.

OBJECTIVE: This study aimed to show the association between internet addiction (IA), sleep quality, and psycho-social problems among secondary school students DESIGN: A cross-sectional, descriptive, and correlational study design was used. SAMPLE: A total of 557 students from four secondary schools in Erbil were selected using multistage cluster sampling MEASUREMENTS: The questionnaires of this research contained socio-demographic data, Internet Addiction Test (IAT), Pittsburgh Sleep Quality Index (PSQI), and Pediatric Symptom Checklist-Y (PSC-Y) questionnaire. RESULTS: Findings indicated that students displayed a mild IA, averaging a score of 42.9 ± 19.18. Furthermore, the average sleep quality (PSQI) score was 8.95 ± 2.75, indicating moderate sleep disturbance, and the average score for psycho-social problems was 27.78 ± 13.29. Importantly, there was a strong and positive association between IA and psycho-social issues, as shown by a correlation coefficient of 0.31 (p < .001). Sleep quality was correlated with IA and psychosocial issues (p < .001, correlation values: .23 and .27, respectively) CONCLUSIONS: The study highlights the urgent need for health policymakers and nursing managers in Erbil to develop targeted interventions, such as awareness campaigns and digital well-being programs in school curricula, to mitigate the interlinked issues of IA, sleep quality, and psycho-social problems among students.

Investigating the relationship between missed/rationed nursing care and organizational commitment in Iranian nurses.

BACKGROUND AND OBJECTIVE: The primary objective of the nursing profession is to provide comprehensive and appropriate nursing care that meets the individual needs of patients. However, instances of missed/rationed nursing care can jeopardize the delivery of complete and safe healthcare, potentially putting patients' lives at risk. The level of organizational commitment demonstrated by nurses is likely to impact various personnel and organizational factors. Therefore, this study aims to predict instances of missed/rationed nursing care by examining the influence of organizational commitment. METHOD: This descriptive and cross-sectional study will be conducted in 2023. Three hundred nurses working in general and intensive critical care units at Tehran University of Medical Sciences hospitals were randomly selected. Data collection included Allen and Mayer's organizational commitment questionnaires, Kalish's missed care questionnaire, and demographic variables. A multiple linear regression model was used to analyze the prediction of missed care by commitment and other variables. The relationship between these variables was also explored using SPSS version 26 software. FINDINGS: Half of the nurses reported occasionally missing nursing care. Moreover, more than half of the nurses reported moderate organizational commitment in all dimensions. The most significant reasons identified by nurses for missed care were financial resources, human resources, and communication (p < 0.001). There was a significant relationship between missed/rationed nursing care and organizational commitment (p = 0.042). In the multiple regression equation, a significant portion of missed care due to commitment was predicted when considering demographic variables (p < 0.001). CONCLUSION: By understanding the relationship between organizational commitment and missed care, and identifying the factors contributing to missed/rationed care, managers can improve the efficiency of human resources and allocate appropriate financial resources. Establishing effective communication with employees can also enhance their commitment to addressing neglected care, ultimately reducing instances of oversight.

Death Anxiety in Patients with a History of Coronary Artery Bypass Graft Surgery During the COVID-19 Pandemic: The Role of Spiritual Well-Being and Coping Strategies.

Patients who have previously undergone coronary artery bypass surgery (CABG) were prone to death anxiety during the COVID-19 pandemic. It appears that spiritual well-being and appropriate coping strategies may mitigate the harmful effects of death anxiety. Therefore, this study aimed to determine the level of death anxiety in patients with CABG during the COVID-19 pandemic and investigate the relationship between spiritual well-being, coping strategies and death anxiety.This cross-sectional study was conducted on 100 patients with CABG history in Tehran from June 2021 to February 2022. The face-to-face questionnaire, containing questions on demographics, Templer's death anxiety scale, the spiritual well-being questionnaire, and the ways of coping questionnaire was administered to collect data. Statistical analysis was performed using descriptive-analytical statistics, correlation tests, and logistic regression models.Participants' mean age was 55.59 ± 12.78 years. The mean death anxiety score was 10.00 ± 2.16, with 87% of participants reporting high levels and 13% reporting low levels of death anxiety. Based on the results, there was a significant negative correlation between death anxiety and coping strategies, as well as subscales of distancing, seeking social support, accepting responsibility, and planful problem-solving. Logistic regression showed that with the increase in the score of spiritual well-being, the odds of having high levels of death anxiety decreased (p < 0.05). Furthermore, increasing the total score of coping strategies, and the score of self-controlling, seeking social support, accepting responsibility, and planful problem-solving, significantly reduced the odds of high levels of death anxiety (p < 0.05).The study showed that patients with a CABG history experienced high death anxiety during the COVID-19 pandemic. According to the findings, spiritual well-being and coping strategies, especially self-controlling, seeking social support, accepting responsibility, and planful problem-solving, may reduce the odds of severe death anxiety. These should be considered as effective targets for psychological intervention in these patients.

Dental Caries among the Elderly in Iran: A Meta-analysis.

Background: The prevalence of dental caries among the elderly is high worldwide, and dental caries cause the major burden of oral diseases. This meta-analysis aimed to determine the dental caries experience among the elderly in Iran. Methods: A systematic review of the published and grey literature on Iranians aged 65 years or older was performed. Six international and local databases provided the most comprehensive population-based studies. National oral health surveys and national disease and health surveys were considered other primary data sources. The quality of remained studies was assessed by a modified tool designed based on the STROBE statement checklist to evaluate the cross-sectional studies. R Version 3.6.0 was used for statistical analysis. Heterogeneity was assessed using Cochran's Q and F statistics. Subgroup analysis was performed to detect the source of heterogeneity. Funnel plots and Egger's regression intercept test were used to assess publication bias and selective reporting. Results: Overall, 3099 sources were found. After excluding ineligible studies, 46 data points with 10411 people ≥65 years were included in the meta-analysis. The mean pooled decayed, missing, and filled teeth (DMFT) among older people was 26.84 (range, 26.41-27.28). The DMFT was 26.78 (range, 26.12-27.43) in women and 26.91 (range, 26.32-27.50) in men. The mean number of decayed teeth was 1.48 (range, 1.32-1.65). The mean pooled missing teeth was 24.83 (range, 24.20-25.46), and the mean pooled filled teeth was 0.14 (range, 0.12-0.17). The majority (92%) of the DMFT was related to missing teeth. Conclusion: Iranian elderly have almost 5 sound teeth in their mouth on average. The Iranian oral health policymakers should address this considerable burden of dental caries in designing and implementing better oral health policies for the population, especially older Iranian adults.

Serum Vitamin D Status and Cognitive Function in Iranian Older Adults: Evidence from the Birjand Longitudinal Aging Study.

BACKGROUND: There is evidence of the role of vitamin D deficiency in cognitive decline. However, the results of studies regarding the relationship between the reduction of vitamin D concentrations and cognitive impairment are heterogeneous. OBJECTIVES: We aimed to answer the question of whether vitamin D deficiency is associated with cognitive decline in older adults. METHODS: In this cross-sectional study, the baseline data of the Birjand Longitudinal Aging Study (BLAS) were analyzed. Of 1420 participants in the BLAS, 1219 participants aged ≥60 y old were included in the present study. Serum concentrations of 25-hydroxyvitamin D [25(OH)D] were measured by the enzyme-linked immunosorbent assay method. The 6-item Cognitive Impairment Test (6-CIT), Mini-Mental State Examination (MMSE), Category Fluency Test (CFT), and Abbreviated Mental Test Score (AMTS) were used to assess cognitive function. Multiple logistic regression analysis, adjusted for potential confounders, was employed to estimate the association between cognitive function and 25(OH)D concentrations. RESULTS: Among study participants, 905 (74.24%) had sufficient vitamin D concentrations (≥20 ng/ml), 209 (17.15%) had insufficient vitamin D concentrations (12-20 ng/ml), and 105 (8.61%) had vitamin D deficiency (<12 ng/ml). There was no significant correlation between serum 25(OH)D concentrations and scores of 6-CIT (P = 0.279), AMTS (P = 0.181), MMSE (P = 0.118), and CFT (P = 0.259). Also, the prevalence of cognitive impairment had no significant relationship with vitamin D status. Finally, in the multiple logistic regression analysis, there was no association between the insufficient or deficient concentrations of 25(OH)D and impaired cognitive function both before and after adjustment for various cofounders. CONCLUSIONS: The present study found no significant association between vitamin D status and cognitive impairment.

Clinical utility of lipid ratios as potential predictors of metabolic syndrome among the elderly population: Birjand Longitudinal Aging Study (BLAS).

BACKGROUND: Elderly adults are at higher risk of developing metabolic syndrome (MetS). The present study aims to investigate the relationship between lipid ratios and MetS in the elderly population. METHODS: This study was conducted on elderly population of Birjand during 2018-2019. The data of this study was driven from Birjand Longitudinal Aging Study (BLAS). The participants were selected based on multistage stratified cluster sampling. Patients were categorized into quartiles according to the lipid ratios (TG/HDL-C, LDL-C/HDL-C, non-HDL/HDL-C), and the relationship between lipid ratio quartiles and MetS was determined by Logistic Regression using Odds Ratio. Finally, the optimal cut-off for each lipid ratio in MetS diagnosis was calculated according to the Area Under the Curve (AUC). RESULTS: This study included 1356 individuals, of whom 655 were men and 701 were women. In our study, the crude prevalence of MetS was 792 (58%), including 543 (77.5%) women and 249 (38%) men. Increasing trends were observed in quartiles of all lipid ratios for TC, LDL-C, TG, and DBP. TG/HDL was also the best lipid ratio to diagnose the MetS, based on NCEP ATP III criteria. One unit increased in level of TG/HDL resulted in 3.94 (OR: 3.94; 95%CI: 2.48-6.6) and 11.56 (OR: 11.56; 95%CI: 6.93-19.29) increasing risk of having MetS in quartile 3 and 4 compared to quartile 1, respectively. In men and women, the cutoff for TG/HDL was 3.5 and 3.0, respectively. CONCLUSIONS: Our results showed that the TG/HDL-C is superior to the LDL-C/HDL-C and the non-HDL /HDL-C to predict MetS among the elderly adults.

Low physical activity and depression are the prominent predictive factors for falling in older adults: the Birjand Longitudinal Aging Study (BLAS).

BACKGROUND: Falling in the older adults has many irreparable consequences, including hospitalization to long-term care centers and loss of independence, depression and social isolation, financial burden, and death. The present study was conducted to estimate the incidence of falls and their associated factors among community-dwelling older adults. METHODS: This program is a population-based prospective cohort study (≥ 60 years) in Birjand City from 2019 to 2020. A total of 1418 participants were included in the study, and 1344 participants were analyzed according to the inclusion criteria. Thirty-nine risk factors were evaluated. Basic information included demographic information, lifestyle factors, general health and medical history, and mental and functional health. RESULT: The incidence of falls among community-dwelling older adults in the previous approximately 24 months in the present study was 9.26% in women and 2.65% in men. In the multiple Cox proportional regression model based on fall risk factors, there was a strong significant relationship between male sex (HR = 0.37, CI = 0.21 to 0.64), being physically active (HR = 0.59, CI = 0.36 to 0.96), moderate-to-severe depression (HR = 2.97, CI = 1.47 to 6.01), severe depression (HR = 3.26, CI = 1.24 to 8.54), and high risk of falls according to the TUG test (HR = 1.73, CI = 1.10 to 2.72). CONCLUSIONS: Inactivity and depression were recognized as important factors in falls in older adults. It is recommended for older adults to have an active lifestyle to prevent falls and to prioritize the diagnosis and treatment of depression in older adults. Women as a group at higher risk should be considered in prevention programs. In addition, the use of the TUG test to identify high-risk older adults should be considered.

The effects of simulated video education about falling on falling rate and fear of falling among hospitalized elderly people: a randomized clinical trial.

BACKGROUND AND AIM: Management of falling and its consequences is a major challenge of elderly nursing care. An effective educational strategy is essential to prevent falling among elderly people. The aim of this study was to evaluate the effects of simulated video education (SVE) about falling on falling rate and fear of falling (FOF) among hospitalized elderly people. METHODS: This randomized controlled clinical trial was conducted from May 2021 to February 2022. Participants were 132 elderly people conveniently selected from a leading hospital in Qom, Iran, and randomly allocated to an intervention and a control group through block randomization. Data collection instruments were a demographic and clinical questionnaire, a researcher-made falling rate questionnaire, and the Falls Efficacy Scale-International. Participants in the intervention group individually watched three simulated videos (fifteen minutes in total) and had access to the videos for frequent watching. Their FOF was assessed on the first day of hospitalization, hospital discharge, and one and three months after hospital discharge. The data were analyzed at a significance level of less than 0.05 using the SPSS software (v. 16.0). RESULTS: Groups did not significantly differ from each other respecting baseline demographic and clinical characteristics (P > 0.05). After the intervention, falling rate in the intervention group was 46% less than the control group (incidence rate ratio = 0.5454, 95% CI = 0.307-0.968; P = 0.039). Moreover, the posttest mean score of FOF in the intervention group was significantly less than the control group (P < 0.001). CONCLUSION: SVE is effective in significantly reducing falling rate and FOF. Context-based SVE is recommended to reduce falling rate and FOF among hospitalized elderly people. CLINICAL TRIAL REGISTRATION: The effects of simulated video education about falling on falling rate and fear of falling among hospitalized elderly people. CLINICAL TRIAL REGISTRATION: this research was registered (17/09/2021) in the https://www.irct.ir with registration number: IRCT20210910052427N1).

Investigating the Relationship Between Spiritual Health, Meaning in Life, and Death Attitudes among COVID-19 Patients Discharged from ICUs: A Cross-Sectional Study in Iran.

The COVID-19 pandemic has been shown to affect both physical and mental health. Because of this mental health burden, it is important to pay attention to issues such as the relationship between spiritual health, death attitudes and meaning in life - all issues made more prominent during the pandemic. This study was conducted to determine the correlation between these three factors - spiritual health, meaning in life, and death attitudes, among patients with COVID-19 discharged from the intensive care units of hospitals affiliated with Tehran University of Medical Sciences, Tehran, Iran.This cross-sectional, descriptive-analytical study was conducted between April 2020 and August 2021 with 260 participants. The data collection instruments were a demographic characteristics questionnaire, Polotzin and Ellison's Spiritual Health Questionnaire, The Meaning in Life Questionnaire (MLQ), and Death Attitude Profile-Revised (DAP-R).The correlation between meaning in life, spiritual health, and death attitudes was determined by Spearman's correlation coefficient. The research results showed that there is an inverse and significant correlation between spiritual health and death attitudes (p = 0.01); an inverse, but insignificant correlation between existential health and subscales of death attitudes, except for the subscales of approach acceptance and neutral acceptance (p > 0.05); and an inverse, but insignificant, correlation between spiritual health and death attitudes, (p > 0.05). In addition, there was an inverse and significant correlation between the presence of meaning in life and escape acceptance (p = 0.002); an inverse and significant correlation between the search for meaning in life and neutral acceptance (p = 0.007); and an inverse and significant correlation between the meaning in life and death attitudes (p = 0.04). Besides, the findings showed an inverse but insignificant correlation between all spiritual health subscales and the meaning in life subscales (p > 0.05). Spiritual health has an inverse correlation with death attitudes.Also, there is an inverse correlation between the total score of spiritual health and death attitudes. Regarding the subscales of spiritual health, there is an inverse correlation between existential health and death attitudes subscales, except for approach acceptance and neutral acceptance. Also, the results showed an inverse and significant correlation between meaning in life and death acceptance and avoidance subscales, and there was an inverse and significant correlation between the meaning in life and death attitudes. Finally, the increase in spiritual health reduces patients' risks of thinking about death. The research results double the significance of the role of nurses, especially those dealing with critically ill patients and those who have experienced severe disease conditions.

Interactive relationship between Trp metabolites and gut microbiota: The impact on human pathology of disease.

Tryptophan (Trp), an α-amino acid, is the precursor of serotonin (5-hydroxytryptamine, 5-HT), which is involved in a variety of features of metabolic function and human nutrition. Evidence highlights the role of Trp metabolites (exclusively 5-HT) in the gastrointestinal (GI) tract; however, the mechanisms of action involved in the release of 5-HT in the GI tract are still unknown. Considering the fact that variations of 5-HT may facilitate the growth of certain GI disorders, gaining a better understanding of the function and release of 5-HT in the GI tract would be beneficial. Additionally, investigating Trp metabolism may clarify the relationship between Trp and gut microbiota. It is believed that other metabolites of Trp (mostly that of the kynurenine pathway) may play a significant role in controlling gut microbiota function. In this review, we have attempted to summarize the current research investigating the relationship of gut microbiota, Trp and 5-HT metabolism (with particular attention paid to their metabolite type, as well as a discussion of the research methods used in each study). Taking together, regarding the role that Trp/5-HT plays in a range of physical and mental diseases, the gut bacterial types, as well as the related disorders, have been exclusively considered.

Is There Any Link between Cognitive Impairment and Gut Microbiota? A Systematic Review.

BACKGROUND: Symptoms of cognitive impairments vary from mild without clinical manifestation to severe with advanced signs of dementia or Alzheimer's disease (AD). Growing evidence in recent years has indicated the association between the brain and gut microbiota, which has been described as the "gut-brain axis." This systematic review seeks to summarize the primary results from recent human and animal studies regarding the alteration of gut microbiota composition in cognitive disorders. METHODS: A systematic literature search was conducted on PubMed, Scopus, and Web of Science databases up to August 2020. The full texts of the papers were analyzed to retrieve the relevant information. RESULTS: Totally, 24 observational studies (14 animal and 13 human studies) were included. Most of the animal studies were performed on mouse models of AD. Human studies were conducted on patients with Parkinson's disease (3 studies), AD (4 studies), poststroke cognitive impairment patients (1 study), and patients with mild to severe cognitive impairment without mention to the cause of disease (5 studies). More recent evidence suggests that throughout aging Firmicutes and Bifidobacteria decrease but Proteobacteria increases. CONCLUSIONS: The gut microbiota may alter brain function or trigger various psychiatric conditions through the gut-brain axis. Prospective studies are needed in order to explore the role of the gut microbiota in the etiology of dementia and to achieve clinical recommendations.

Low physical activity is the strongest factor associated with frailty phenotype and frailty index: data from baseline phase of Birjand Longitudinal Aging Study (BLAS).

BACKGROUND: Frailty is the most complicated expression of aging that is related to disability or multi-morbidity. The aim of the present study was to estimate the prevalence of frailty and its associated factors among community-dwelling aged population. METHODS: A total of 1529 eligible community- dwelling older adults (≥ 60 years) were enrolled in the baseline phase of Birjand Longitudinal Aging Study (BLAS) from 2019 to 2020. Their frailty status was assessed using the Fried's frailty phenotype and frailty index. Sociodemographic factors, including sex, age, marital status, and education level, were collected. Health status assessment included the history of hypertension, diabetes mellitus, cardiovascular disease, Alzheimer's diseases and dementia, and other health conditions. Furthermore, functional assessment (ADL, IADL) and anthropometric measurements including height, weight, waist, calf, and mid-arm circumference were made and the body mass index was calculated. The nutrition status and polypharmacy (use 3 or more medication) were also evaluated. RESULTS: The prevalence of frailty was 21.69% according to the frailty phenotype and 23.97% according to the frailty index. A multiple logistic regression model showed a strong association between low physical activity and frailty phenotype (OR = 36.31, CI = 16.99-77.56, P < 0.01), and frailty index (OR = 15.46, CI = 5.65-42.34, P < 0.01). Other factors like old age (≥80), female sex, malnutrition, polypharmacy, obesity, and arthritis were also associated with frailty. The Kappa coefficient of the agreement between these two instruments was 0.18. CONCLUSION: It seems that low physical activity is the most important determinant of frailty. Low physical activity and some other factors may be preventable or modifiable and thus serve as clinically relevant targets for intervention.

Relationship between moral sensitivity and the quality of nursing care for the elderly with Covid-19 in Iranian hospitals.

BACKGROUND: The quality of care has a significant impact on the condition of elderly patients. Many factors affect the quality of care, including ethical considerations. Ethical considerations, such as moral sensitivity, change in times of crisis. The present study was conducted to assess the relationship between moral sensitivity and the quality of nursing care for the elderly with Covid-19 in Iranian hospitals. METHODS: This was a cross-sectional descriptive correlational study. The participants included 445 nurses that were selected by quota sampling method from hospitals admitting COVID-19 patients. The data were collected using the Moral Sensitivity Questionnaire (MSQ) and Quality Patient Care Scale (QUALPAC) as self-reports. We used the SPSS software v.16 for statistical analysis. RESULTS: The total score of moral sensitivity and quality of care was 52.29 ± 16.44 and 2.83 ± 0.23, respectively. Moral sensitivity negatively correlates with psychological, social, and physical aspects (P < 0.05). Modifying autonomy, interpersonal orientation, and experiencing moral conflict predicted ß = 0.10 of the psychosocial aspect of quality of care. Structural moral meaning and expressing benevolence predicted the changes in the physical dimension of quality of care (ß = 0.02). CONCLUSION: The quality of care had a significant inverse correlation with moral sensitivity. Multiple regression analysis showed that modifying autonomy, interpersonal orientation, and experiencing moral conflict could predict the psychosocial dimensions. Structuring moral meaning could predict the physical dimension. The communication aspects were not related to any of the dimensions of moral sensitivity.

The relationship of caregiver strain with resilience and hardiness in family caregivers of older adults with chronic disease: a cross-sectional study.

BACKGROUND: Providing long-term home care to older adults with chronic diseases may endanger the physical, mental, social, and spiritual health of caregivers and lead to care strain. OBJECTIVE: This study aimed to assess the relationship of caregiver strain with resilience and hardiness in family caregivers of older adults with chronic disease. METHODOLOGY: This cross-sectional correlational study was conducted in 2020-2021 in Tehran. Participants were 230 family caregivers randomly recruited from 8 urban health care centers. Data were collected using a personal characteristics questionnaire, the Modified Caregiver Strain Index, Connor-Davidson Resilience Scale, Family Hardiness Index, and the data were analyzed by using SPSS 22 version. Pearson's correlation coefficient was applied for data analysis. P-values ≤0.05 were considered significant. RESULTS: A total of 230 caregivers participated in the study. The mean age of participants was (46.65 ± 13.63) years and most of them were female (73.9%). Mean scores of caregiver strain, resilience, and hardiness in family caregivers were 16.23 ± 4.5, 39.89 ± 10.9, and 31.21 ± 7.79, respectively. Pearson correlation showed a significant and inverse correlation between caregiver strain and resilience (r = -0.310, P = 0.002), and also a significant and inverse relationship between caregiver strain and hardiness (r = -0.276, P = 0.001). CONCLUSION: In this study, family caregivers had moderate caregiver strain, low resilience, and high hardness. Caregiver strain in family caregivers of older adults with chronic disease is an important health issue associated with resilience and hardiness. To promote health, effective adaptation to long-term care, and reduce caregiver strain, designing effective interventions to increase resilience and hardiness in family caregivers seems necessary.

Written and computer simulation on the moral sensitivity of nurses.

Background: Moral sensitivity is the first step towards ethical decision-making. This sensitivity should form a basic attitude in healthcare team members, particularly nurses, toward providing effective and ethical care. This is highlighted in intensive care units (ICUs) where close attention should be paid to patient rights and moral or ethical decision-making.Objective: The present study aimed at determining and comparing the effect of written simulation and computer simulation of a virtual patient on the development of moral sensitivity of ICU nurses.Research design: Randomized controlled trial with one control arm and two experimental arms.Participants and content: This study involved 204 ICU nurses working in hospitals affiliated to Tehran University of Medical Sciences, Tehran, Iran, from 2019 to 2021 using a random allocation method. The participants were allocated to three groups comprising virtual patient computer simulation, written simulation, and the no simulation control group. After training based on a Patient Rights Charter, five scenarios, with themes reflecting the clauses of the Patient's Rights Charter, were written as a computer program and text for the computer simulation and written simulation groups, respectively. Finally, nurses' moral sensitivity was assessed using the Lützén moral sensitivity questionnaire as pre- and post-tests (immediately and 2 months after the intervention).Ethical considerations: Ethical permission was obtained for the study. All the participants signed the informed consent before the study onset.Results: The study results showed a significant difference in moral sensitivity among the three groups before the intervention (p = 0.003). Immediately after the intervention compared to pre-intervention, the three groups showed no significant differences in this regard (p = 0.056), however a significant difference among the three groups was found 2 months post-intervention (p < 0.001).

A perspective on the sense of loneliness and its determinants in Iranian older people.

BACKGROUND: The sense of loneliness is one of the common problems of older people and their quality of life, and is affected by many factors such as personal resources, gender, health condition, and age. This study investigates the determinants of the sense of loneliness between older men and women in Birjand. METHODS: This study was a part of the community-based prospective cohort study of the Birjand Longitudinal Aging Study (BLAS). Individuals over 60 years of age and their families (selected by random cluster sampling) were assessed through structured interviews with questionnaires such as Patient Health Questionnaire, Short-Form-12, Longitudinal Aging Study Amsterdam Physical Activity Questionnaire, loneliness, and social support questions. RESULTS: The mean age of the participants in the study was 68.59 ± 6.72, and 53.2% were women. Based on the findings of pathway analysis, the most critical determinants of loneliness in older men and women were the number of children (total effect = -0.112, P = 0.006) and mood, respectively (total effect = 0.142, P < 0.001). According to results, older people with fewer children feel lonelier. CONCLUSION: Compared with men, emotional loneliness is more common in older women. Older women, who lost their husbands, suffer from loneliness, mental health disorders, and low quality of life.
