Restless legs syndrome variants: A systematic review

Introduction

Restless Legs Syndrome (RLS) is a clinical syndrome that may manifest itself in non-leg parts of the body as well, called RLS variant, which is considered a distinct entity by some researchers. In this systematic review, we tried to evaluate various clinical features and effective treatments of RLS variants and compare them with that of typical RLS.

Methods

This study was conducted following the PRISMA guideline. The primary search was performed in the data resources of Medline (PubMed), Web of Science, and Scopus, as well as the Google Scholar search engine. The required data were extracted from the studies.

Results

In this review, 1565 studies were initially identified and finally 39 studies were selected. The most common RLS variants were observed to involve hands, head, abdomen, and genitalia. These patients mostly complained of sleep disturbance and feelings of itching, tingling and twitching. Supportive diagnostic criteria of RLS including familial history of RLS, periodic limb movements during sleep (PLMS) and response to treatment with dopaminergic agents were assessed.

Conclusion

It seems that patients with RLS variant can undergo the same diagnostic and therapeutic work-up as patients with conventional RLS. It is suggested that these two disorders fall into the same syndromic spectrum.

Attenuation of cannabis withdrawal symptoms by Prosopis farcta extract, its luteolin and melatonin in mice: Involvement of brain-derived neurotrophic factor and dopamine

The aim of this study was the identification of luteolin in Prosopis farcta extract (PFE) and melatonin to evaluate its effect on THC withdrawal syndrome in mice. Luteolin was identified by high-performance liquid chromatography (HPCL). Signs of toxicity of mice in PFE and luteolin were monitored for LD50 calculation. The behavioral symptoms of THC withdrawal (stereotypies, ambulation, and inactivity time) induced by the rimonabant challenge were illustrated in THC-dependent mice receiving PFE, luteolin, and melatonin. The expression of mature BDNF (mBDNF) was evaluated by Western blot analysis. The dopamine concentrations were measured using HPLC. PFE and luteolin LD50 were 650 and 220 mg/kg, respectively. PFE (300 mg/kg), all doses of luteolin, and melatonin increased significantly the mBDNF expression and decreased the dopamine concentration. The findings suggest that PFE, luteolin, and melatonin are mighty in reducing the signs of THC withdrawal. It seems these effects were due to a decrease in dopamine concentration level and an increase in mBDNF protein expression in mice brains.

A systematic review and meta-analysis of musculoskeletal disorders among firefighters

INTRODUCTION

Due to the nature of their job, firefighters face many ergonomic risk factors and are exposed to several musculoskeletal disorders (MSDs). The aim of this systematic review and meta-analysis was to investigate the prevalence of MSDs among firefighters.

MATERIALS AND METHODS

This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The literature search was conducted in the databases of PubMed, Scopus, Web of Science, Science Direct, SID, ISC and Google Scholar without applying a time limitation until the end of July 2022. The random effects model was used for meta-analysis, and the I2 index was used to check heterogeneity among studies. The data were analyzed using STATA version 14 software.

RESULTS

The primary literature searches in the databases identified 1,291 articles, 26 of which were entered the meta-analysis stage after screening, study selection, and quality assessment, including 36,342 firefighters. Based on the results of a meta-analysis, the overall prevalence of MSDs among firefighters was 46.39% (95% CI: 32.45-60.32, I2 = 99.7%, P < 0.001). The prevalence of MSDs was also investigated at neck (18.36%), low back (34.32%), shoulder (18.68%), hands (7.43%), upper back (10.15%), knee (19.97%) and foot (6.66%).

CONCLUSION

Considering the relatively high prevalence of MSDs among firefighters and their higher exposition to specific job-related risk factors of MSDs compared to other professions, it is suggested to provide firefighters with appropriate training, implement ergonomic interventions, and regularly screen them to reduce MSDs.

Comparison of machine learning algorithms to predict intentional and unintentional poisoning risk factors

Introduction

A major share of poisoning cases are perpetrated intentionally, but this varies depending on different geographical regions, age spectrums, and gender distribution. The present study was conducted to determine the most important factors affecting intentional and unintentional poisonings using machine learning algorithms.

Materials and methods

The current cross-sectional study was conducted on 658 people hospitalized due to poisoning. The enrollment and follow-up of patients were carried out during 2020-2021. The data obtained from patients' files and during follow-up were recorded by a physician and entered into SPSS software by the registration expert. Different machine learning algorithms were used to analyze the data. Fit models of the training data were assessed by determining accuracy, sensitivity, specificity, F-measure, and the area under the rock curve (AUC). Finally, after analyzing the models, the data of the Gradient boosted trees (GBT) model were finalized.

Results

The GBT model rendered the highest accuracy (91.5 ± 3.4) among other models tested. Also, the GBT model had significantly higher sensitivity (94.7 ± 1.7) and specificity (93.2 ± 4.1) compared to other models (P < 0.001). The most prominent predictors based on the GBT model were the route of poison entry (weight = 0.583), place of residence (weight = 0.137), history of psychiatric diseases (weight = 0.087), and age (weight = 0.085).

Conclusion

The present study suggests the GBT model as a reliable predictor model for identifying the factors affecting intentional and unintentional poisoning. According to our results, the determinants of intentional poisoning included the route of poison entry into the body, place of residence, and the heart rate. The most important predictors of unintentional poisoning were age, exposure to benzodiazepine, creatinine levels, and occupation.

Association of Serum Vitamin D Levels with the Risk of Suicidal Behavior in Ilam, Iran: A Brief Report

There are conflicting reports on the effect of serum vitamin D (VD) levels on the development of suicidal behavior. VD deficiency is prevalent in Ilam province, and this region has the highest suicide mortality rate in Iran. The present study aimed to evaluate a possible association between serum VD levels and the risk of suicide among the inhabitants of Ilam province. A total of 157 suicide attempters (case group) and 314 age- and sex-matched individuals (control group) without a history of suicide attempts were recruited into the study. Suicide attempters were admitted to the Emergency Department of Ilam Shahid Mostafa Khomeini Hospital (Ilam, Iran) between March 2018 and March 2019. The individuals in the control group were randomly selected from those referred to various medical laboratories in Ilam during the same period. The participants in both groups were aged 18-35 years, and none had a history of kidney, liver, or endocrine diseases. Serum VD levels were measured using the enzyme-linked immunosorbent assay method. Categorical and continuous variables were compared using the Chi square test and independent samples t test, respectively. Serum VD level in the control group (31.5±0.2 ng/mL) was significantly lower than in the case group (43.1±0.1 ng/mL) (P<0.001). The results of logistic regression analysis showed that an increase in serum VD score was associated with an increase in the likelihood of suicide attempts (OR=1.05, 95% CI=1.03-1.06, P<0.001). Our findings confirmed the role of VD deficiency in the development of suicidal behavior. However, it is not a significant factor in its pathogenesis.

The effects of prevalence of inequalities in mental disorders between groups using Blinder- Oaxaca decomposition

BACKGROUND

The prevalence of inequalities in sociodemographic factors in some mental disorders (MDs) has been shown in previous reports. The aim of this study was to assess the main contributors that affected prevalence of inequalities in MDs between groups.

MATERIALS AND METHODS

This was a cross-sectional study that was conducted on adults in 10 cities from Ilam province. We selected participants using cluster sampling; clusters were cities (n₁ = 10), geographical area (n₂ = 153), and households (n₃ = 382). Screening tools and clinical interview were applied through standardized and validated questionnaires, namely, GHQ-28 and DSM-IV-TR, respectively. Participants were divided into socioeconomic groups via principal composition analysis (PCA). Blinder-Oaxaca approach was applied to distinguish the gap in inequalities between groups.

RESULTS

The prevalence of MDs in the advantage group was 22.6% and, in disadvantages was 35.6%. The concentration index (CI) of the MD prevalence rate was -0.013 (95% CI: -0.022, -0.004) which indicated that MDs were more common in the disadvantaged groups. The odds of MDs in advantaged people was 81% more compared to the disadvantaged group (OR: 1.81; 95% CI: 1.28, 2.57), also in females compared to males (1.60; 95% CI: 1.21, 2.24). Analysis of gap inequality between groups showed that the gap in prevalence rates of MDs between groups was 12%.

CONCLUSION

This study revealed a socioeconomic inequality in MD rates in the adult population. Therefore, results of this study provide contributors in MDs inequality in order to control and reduce the prevalence of MDs in the community.

The Effect of a Non-Pharmacological Multicomponent Pain Management Program on Pain Intensity and Quality of Life in Community-Dwelling Elderly Men With Chronic Musculoskeletal Pain

BACKGROUND AND AIM

Improving the level of care for the elderly with musculoskeletal pain requires pharmacological and non-pharmacological pain control methods. This study aimed to investigate the effect of a non-pharmacological pain management intervention on pain intensity and quality of life in community-dwelling older men with musculoskeletal pain who were referred to comprehensive healthcare centers in the city of Ilam, Iran.

MATERIALS AND METHODS

A quasi-experimental study with pre and post-test design was performed on 65 older men with chronic musculoskeletal pain. The samples were selected regarding inclusion criteria as available and randomly assigned to either the control (usual care) or the experimental group (educational intervention plus physical exercises). Baseline characteristics of participants, the Visual Analogue Scale, and the CASP-19 Quality of Life were used to collect data. Data were analyzed by SPSS software using the ANCOVA, independent and paired t-test, and chi-square test at the statistically significant level of 5 %.

RESULTS

According to the findings, there was a significant difference between the experimental and control groups in terms of quality of life (p < .05) and pain intensity (p < .05) after the intervention. No relevant differences were found between groups regarding demographic characteristics at baseline.

CONCLUSIONS

A six-week physical activity and education program for community-dwelling older men with chronic musculoskeletal pain could improve quality of life and decrease pain intensity after a one-month follow-up compared with usual care. Therefore, it seems necessary to consider pain management programs in the elderly care program and familiarize health care professionals with these pain control methods.

Relationship between Moral Intelligence and Clinical Competency of Nurses in Ilam Educational Hospitals

"In this descriptive-analytical study, 110 nurses working in educational hospitals of the Ilam University of Medical Sciences were included. Participants were selected using a random sampling method. The data collection tools were the demographic information form, the moral intelligence questionnaire of Lenik and Kiel (2005), and the standard clinical competency assessment questionnaire (CIRN). Data were analyzed using SPSS software, version 21. Descriptive and inferential statistical tests were used to analyze the data. The mean ± SD score of nurses' moral intelligence and clinical competency was estimated at 157.59 ± 26.60 and 136.65 ± 46.08, respectively. Fifty-one percent of participants had low clinical competency, and 46% had high clinical competency. There was a significant association between moral intelligence and clinical competency (p<0.05). "

Death Trends and Years of Life Lost Due to Social Harms Such as Suicide, Homicide, and Addiction, Ilam Province, 2009-2019

Objective

This study aimed to investigate the death trend and years of life lost (YLL) caused by social harm in Ilam province.

Methods

This cross-sectional study was conducted in Ilam province from 2009 to 2019. To estimate YLL, all deaths caused by suicide, homicide, and addiction were included in the study. The data were collected from the Forensic Medicine Organization. The analysis was carried out using SPSS software (version 23.0). A p-value of <0.05 was considered statistically significant.

Results

Between 2009 and 2019, there were 1712 occurrences of suicide, homicide, and addiction, which resulted in a total of 62,605 years of lost life (53,934 per 100,000 people). The highest frequency was related to the age group of 15-29 years, while the lowest was related to the age group of 0-14 years (p<0.001). During the studied period, men were more likely than women to commit suicide, homicide, and addiction in Ilam (p>0.439). Between 2009 and 2019, the number of suicides and homicides in Ilam province started a decreasing trend for both sexes, while the number of deaths caused by addiction was increasing.

Conclusion

The results of this study indicated that the age groups of 15-29 years had the highest rate of YLL caused by suicide, homicide, and addiction for both sexes. Furthermore, the findings showed that YLL decreased for suicide and homicide, but increased for addiction.

The total YLLs of suicide and homicide were 15685 and 5317, respectively. 522 per 100,000 populations were suicide and 117 for homicide. The YLL and 95% confidence interval form suicide was 34.4 (32.8-36.1) for both sexes that 33.7 (31.6-35.8) for men, and 35.5 (32.7-38.3) for women. In this study period, YLLs rate began to increase over the years in both injury-related in 2016.

CONCLUSION

Results of this study disclosed the most prominent contribution of men and peoples aged 15-29 to the YLLs. Also our results indicate a recent increase in suicide and homicide YLLs for both genders.

The frequency, related cause of disease, and treatment of hepatitis B virus infection: A systematic review and meta-analysis in Iran

Background:

Hepatitis B virus (HBV) is one of the most dreadful viruses causing high mortality rates and serious damages to hepatocytes. The aim of this study was to assess the frequency, related causes/risk factors, and treatments of HBV infection in Iran by systematic review and meta-analysis.

Materials and Methods:

The data were obtained by a literature search in the PubMed, Scopus, SID, and Web of Sciences databases. Keywords included prevalence, risk factors, causes, treatment, and HBV. The Persian equivalents of these keywords were also searched. The time span included 2004 to2021. The Q and I² statistics were used to check heterogeneity among studies. The data were analyzed using Stata (version 14).

Results:

The frequencies of HBV infection and its pharmaceutical therapy were P = 6% (95% confidence interval [CI]: 4–9, I² = 95.2%, P < 0.001) and 19% (95% CI: 18%–30%, I² = 98.9%, P < 0.001), respectively. The most common risk factors/causes of HBV were narcotic consumption, blood-related factors, and transmission from infected individuals with the respective frequencies of 27% (95% CI: 16%–38%, I² = 88.7%, P < 0.001), 32% (95% CI: 11%–53%, I² = 99.8%, P < 0.001), 25% (95% CI: 10%–41%, I² = 99.3%, P < 0.001), and 15% (95% CI: 7%–22%, I² = 98.4%, P < 0.001), respectively.

Conclusion:

The most important causes of HBV infection were transmission from infected people, narcotic consumption, and blood-related factors. The main therapeutic intervention for HBV was pharmaceutical therapy.

Association between common stressful life events and coping strategies in adults

BACKGROUND

As shown in previous persons that used the effective coping strategies are more aware to recent stressful life events in their live, this study conducted to investigate the main stressful life events and common coping styles in adult's population.

MATERIALS AND METHODS

This cross-sectional study was conducted in 2018. In overall, 345 persons aged 18 years and more by stratified cluster sampling were enrolled in the study. The valid questionnaires including the coping inventory for stressful situations-21, the Holmes-Rahe Stress Inventory, and 28-item General Health Questionnaire (GHQ-28) were used to interview. The analysis of variance and t-student (t-test) was used to determine the association between the two variables. The statistical significance level was considered <0.05.

RESULTS

The top three importance events among 43 stressful items in our study were change in financial state, gain of a new family member, and death of close family member. We found that task-oriented coping (P < 0.001) and avoidance-oriented coping (P = 0.021) significantly more used in males compered to females. According to Holmes-Rahe life stress inventory instructions only 4.7% of participants are prone to getting ill in next 2 years.

CONCLUSION

The results of this study showed a positive relationship between coping styles and lower risk of mental health problems and stressful life events. Hence, activities and training programs aiming to enhance personal approach coping skills is important to reduce of side effects of stressful life events especially those recently exposed to negative life events and stresses.

Relationship between internet addiction and mental health in adolescents

BACKGROUND

Internet addiction (IA) currently is the major public health concern, especially in adolescents, although the results of previous reports are not generally uniform. This study was conducted to determine IA in adolescents and to examine the correlation of IA with mental health in adolescents.

METHODS

This cross-sectional study was conducted in 2019 in Ilam city. In this study, 362 persons were included using stratified cluster sampling; clusters were geographical area and schools. The valid questionnaires including Internet Addiction Test and 28-item General Health Questionnaire (GHQ-28) were used to interview. The correlation statistical technique was used to determine the association between the two variables. The significance level was considered <0.05.

RESULTS

The mean ± standard deviation age of the responders was 16.40 ± 2.47 years; the total score of IA and mental health was 43.02 ± 16.50 and 19.27 ± 9.72, respectively. We found that 5.5% of the adolescents had a severe level of IA. The lack of control with anxiety, neglect work and social dysfunction, and neglect social life and severe depression in internet users were found to be statistically significant: r (365) = 0.151, P < 0.033; r (365) = 0.126, P < 0.021; and r (365) = 0.125, P < 0.033, two-tailed, respectively.

CONCLUSION

According to the results, the excessive use of internet, lack of control, and neglect social life are significantly correlated with mental health in adolescents; these results could be contribute to improve the theoretical models for IA in adolescents.

The association between nurses' moral distress and sleep quality and their influencing factor in private and public hospitals in Iran

BACKGROUND

Nurses in their workplace, for a variety of reasons, always face moral distress that is an underlying issue in the nursing profession, which can lead to problems such as reduced quality and quantity of care and sleep disorder. Besides, given the increased privatization of hospitals, this study aimed to explore the association between nurses' moral distress and sleep quality and its comparison among nurses in private and public hospitals.

MATERIALS AND METHODS

This was a descriptive-analytical study involving 150 nurses working in Ilam Province hospitals. Sampling conducted using a multistage random sampling method. Data were collected through the questionnaire of sociodemographic characteristics, the Corley's Moral Distress Scale, and the Pittsburgh Sleep Quality Index. Data were analyzed using SPSS software version 22. Descriptive statistics such as frequency, mean, ANOVA, independent t-test, multiple linear regression, and Pearson correlation coefficient at the significant level of P < 0.05 were calculated.

RESULTS

The analysis revealed that moral distress was positively associated with sleep quality. Furthermore, the scores of nurses' moral distress and sleep quality were different in private and public hospitals, so that the level of moral distress in the public hospital and sleep quality in the private hospital was higher and lower, respectively, but the difference was not statistically significant. Moreover, sleep quality, and the type of employment was the most important predicting variables of moral stress (B = 1.86) and sleep quality (B = 2.39), respectively.

CONCLUSION

According to the study results, a positive and significant association was found between moral distress and nurses' sleep quality. It is recommended that appropriate strategies and training program be formulated by the health-care system to increase nurses' ability to combat moral distress adverse effects.

Global burden of 87 risk factors in 204 countries and territories, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND

Rigorous analysis of levels and trends in exposure to leading risk factors and quantification of their effect on human health are important to identify where public health is making progress and in which cases current efforts are inadequate. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 provides a standardised and comprehensive assessment of the magnitude of risk factor exposure, relative risk, and attributable burden of disease.

METHODS

GBD 2019 estimated attributable mortality, years of life lost (YLLs), years of life lived with disability (YLDs), and disability-adjusted life-years (DALYs) for 87 risk factors and combinations of risk factors, at the global level, regionally, and for 204 countries and territories. GBD uses a hierarchical list of risk factors so that specific risk factors (eg, sodium intake), and related aggregates (eg, diet quality), are both evaluated. This method has six analytical steps. (1) We included 560 risk-outcome pairs that met criteria for convincing or probable evidence on the basis of research studies. 12 risk-outcome pairs included in GBD 2017 no longer met inclusion criteria and 47 risk-outcome pairs for risks already included in GBD 2017 were added based on new evidence. (2) Relative risks were estimated as a function of exposure based on published systematic reviews, 81 systematic reviews done for GBD 2019, and meta-regression. (3) Levels of exposure in each age-sex-location-year included in the study were estimated based on all available data sources using spatiotemporal Gaussian process regression, DisMod-MR 2.1, a Bayesian meta-regression method, or alternative methods. (4) We determined, from published trials or cohort studies, the level of exposure associated with minimum risk, called the theoretical minimum risk exposure level. (5) Attributable deaths, YLLs, YLDs, and DALYs were computed by multiplying population attributable fractions (PAFs) by the relevant outcome quantity for each age-sex-location-year. (6) PAFs and attributable burden for combinations of risk factors were estimated taking into account mediation of different risk factors through other risk factors. Across all six analytical steps, 30 652 distinct data sources were used in the analysis. Uncertainty in each step of the analysis was propagated into the final estimates of attributable burden. Exposure levels for dichotomous, polytomous, and continuous risk factors were summarised with use of the summary exposure value to facilitate comparisons over time, across location, and across risks. Because the entire time series from 1990 to 2019 has been re-estimated with use of consistent data and methods, these results supersede previously published GBD estimates of attributable burden.

FINDINGS

The largest declines in risk exposure from 2010 to 2019 were among a set of risks that are strongly linked to social and economic development, including household air pollution; unsafe water, sanitation, and handwashing; and child growth failure. Global declines also occurred for tobacco smoking and lead exposure. The largest increases in risk exposure were for ambient particulate matter pollution, drug use, high fasting plasma glucose, and high body-mass index. In 2019, the leading Level 2 risk factor globally for attributable deaths was high systolic blood pressure, which accounted for 10·8 million (95% uncertainty interval [UI] 9·51-12·1) deaths (19·2% [16·9-21·3] of all deaths in 2019), followed by tobacco (smoked, second-hand, and chewing), which accounted for 8·71 million (8·12-9·31) deaths (15·4% [14·6-16·2] of all deaths in 2019). The leading Level 2 risk factor for attributable DALYs globally in 2019 was child and maternal malnutrition, which largely affects health in the youngest age groups and accounted for 295 million (253-350) DALYs (11·6% [10·3-13·1] of all global DALYs that year). The risk factor burden varied considerably in 2019 between age groups and locations. Among children aged 0-9 years, the three leading detailed risk factors for attributable DALYs were all related to malnutrition. Iron deficiency was the leading risk factor for those aged 10-24 years, alcohol use for those aged 25-49 years, and high systolic blood pressure for those aged 50-74 years and 75 years and older.

INTERPRETATION

Overall, the record for reducing exposure to harmful risks over the past three decades is poor. Success with reducing smoking and lead exposure through regulatory policy might point the way for a stronger role for public policy on other risks in addition to continued efforts to provide information on risk factor harm to the general public.

Estimating global injuries morbidity and mortality: methods and data used in the Global Burden of Disease 2017 study

BACKGROUND

While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria.

METHODS

In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced.

RESULTS

GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes.

CONCLUSIONS

GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future.

Mapping geographical inequalities in access to drinking water and sanitation facilities in low-income and middle-income countries, 2000-17

BACKGROUND

Universal access to safe drinking water and sanitation facilities is an essential human right, recognised in the Sustainable Development Goals as crucial for preventing disease and improving human wellbeing. Comprehensive, high-resolution estimates are important to inform progress towards achieving this goal. We aimed to produce high-resolution geospatial estimates of access to drinking water and sanitation facilities.

METHODS

We used a Bayesian geostatistical model and data from 600 sources across more than 88 low-income and middle-income countries (LMICs) to estimate access to drinking water and sanitation facilities on continuous continent-wide surfaces from 2000 to 2017, and aggregated results to policy-relevant administrative units. We estimated mutually exclusive and collectively exhaustive subcategories of facilities for drinking water (piped water on or off premises, other improved facilities, unimproved, and surface water) and sanitation facilities (septic or sewer sanitation, other improved, unimproved, and open defecation) with use of ordinal regression. We also estimated the number of diarrhoeal deaths in children younger than 5 years attributed to unsafe facilities and estimated deaths that were averted by increased access to safe facilities in 2017, and analysed geographical inequality in access within LMICs.

FINDINGS

Across LMICs, access to both piped water and improved water overall increased between 2000 and 2017, with progress varying spatially. For piped water, the safest water facility type, access increased from 40·0% (95% uncertainty interval [UI] 39·4-40·7) to 50·3% (50·0-50·5), but was lowest in sub-Saharan Africa, where access to piped water was mostly concentrated in urban centres. Access to both sewer or septic sanitation and improved sanitation overall also increased across all LMICs during the study period. For sewer or septic sanitation, access was 46·3% (95% UI 46·1-46·5) in 2017, compared with 28·7% (28·5-29·0) in 2000. Although some units improved access to the safest drinking water or sanitation facilities since 2000, a large absolute number of people continued to not have access in several units with high access to such facilities (>80%) in 2017. More than 253 000 people did not have access to sewer or septic sanitation facilities in the city of Harare, Zimbabwe, despite 88·6% (95% UI 87·2-89·7) access overall. Many units were able to transition from the least safe facilities in 2000 to safe facilities by 2017; for units in which populations primarily practised open defecation in 2000, 686 (95% UI 664-711) of the 1830 (1797-1863) units transitioned to the use of improved sanitation. Geographical disparities in access to improved water across units decreased in 76·1% (95% UI 71·6-80·7) of countries from 2000 to 2017, and in 53·9% (50·6-59·6) of countries for access to improved sanitation, but remained evident subnationally in most countries in 2017.

INTERPRETATION

Our estimates, combined with geospatial trends in diarrhoeal burden, identify where efforts to increase access to safe drinking water and sanitation facilities are most needed. By highlighting areas with successful approaches or in need of targeted interventions, our estimates can enable precision public health to effectively progress towards universal access to safe water and sanitation.

Investigating the sexual quality of life and its relationship with general health in older men in Iran

INTRODUCTION

Sexual problems in elder people are considered as a public health concern and can affect their overall health and quality of life. This study aimed to investigate the sexual quality of life and its relationship with general health in older men in the west of Iran.

METHODS

This was a cross-sectional study among 362 older men aged 60 years or older attending Comprehensive Health Care Centers in Ilam, Iran. Samples selected through Quota sampling method and simple random sampling. Data were collected using the Sexual Quality of Life Questionnaire-Male and General Health Questionnaire-28.

RESULTS

The mean ± standard deviation (SD) of age was 69.9 ± 8.1 years. The mean ± SD score of sexual quality of life and general health of older men was 46.6 ± 14.6 and 19.2 ± 9.7, respectively. A positive and significant association was found between sexual quality of life and general health (P < 0.001, r = -0.41). Moreover, general health, age, sleep problems, and the level of education were the important predictors for sexual quality of life in elder men (P < 0.05).

CONCLUSION

According to the results, the sexual quality of life of participants was at a moderate level. Since only some factors influencing the sexual quality of life were ascertained, further studies are required to investigate all factors influencing older men's sexual quality of life.

Mapping geographical inequalities in childhood diarrhoeal morbidity and mortality in low-income and middle-income countries, 2000-17: analysis for the Global Burden of Disease Study 2017

BACKGROUND

Across low-income and middle-income countries (LMICs), one in ten deaths in children younger than 5 years is attributable to diarrhoea. The substantial between-country variation in both diarrhoea incidence and mortality is attributable to interventions that protect children, prevent infection, and treat disease. Identifying subnational regions with the highest burden and mapping associated risk factors can aid in reducing preventable childhood diarrhoea.

METHODS

We used Bayesian model-based geostatistics and a geolocated dataset comprising 15 072 746 children younger than 5 years from 466 surveys in 94 LMICs, in combination with findings of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017, to estimate posterior distributions of diarrhoea prevalence, incidence, and mortality from 2000 to 2017. From these data, we estimated the burden of diarrhoea at varying subnational levels (termed units) by spatially aggregating draws, and we investigated the drivers of subnational patterns by creating aggregated risk factor estimates.

FINDINGS

The greatest declines in diarrhoeal mortality were seen in south and southeast Asia and South America, where 54·0% (95% uncertainty interval [UI] 38·1-65·8), 17·4% (7·7-28·4), and 59·5% (34·2-86·9) of units, respectively, recorded decreases in deaths from diarrhoea greater than 10%. Although children in much of Africa remain at high risk of death due to diarrhoea, regions with the most deaths were outside Africa, with the highest mortality units located in Pakistan. Indonesia showed the greatest within-country geographical inequality; some regions had mortality rates nearly four times the average country rate. Reductions in mortality were correlated to improvements in water, sanitation, and hygiene (WASH) or reductions in child growth failure (CGF). Similarly, most high-risk areas had poor WASH, high CGF, or low oral rehydration therapy coverage.

INTERPRETATION

By co-analysing geospatial trends in diarrhoeal burden and its key risk factors, we could assess candidate drivers of subnational death reduction. Further, by doing a counterfactual analysis of the remaining disease burden using key risk factors, we identified potential intervention strategies for vulnerable populations. In view of the demands for limited resources in LMICs, accurately quantifying the burden of diarrhoea and its drivers is important for precision public health.

The effect of performance feedback and educational video on endotracheal-suctioning practices of critical care nurses

INTRODUCTION

Majority of critical care nurses do not have desirable skills in performing endotracheal tube suctioning (ETS) despite related training taught in the curricula. This study aimed to investigate and compare the effect of education through video and performance feedback (PF) on nurses' skills in performing ETS.

METHODS

This was a quasi-experimental study. The sample size comprised of all nurses (n = 49) working in the intensive care unit of one of the educational hospital located in one of the western cities of Iran. Nurses were assigned to either one of educational video (EV) and PF groups. Data were collected using a 25-item structured best practices information sheet. Data were analyzed using SPSS software version 20 (SPSS Inc., Chicago, IL, USA).

RESULTS

After the interventions, no significant difference was found in the total mean score of nurses' practice in ETS between those who received education through EV and those who received through PF (16.3 vs. 15.1) (P > 0.05). Before and after the intervention, a significant improvement was observed in the total mean score and other dimensions of nurses' practice in endotracheal suctioning (P < 0.0001).

CONCLUSIONS

The results showed that both of methods through feedback and EV are useful in improving nurses' ETS practice. However, further studies are required to examine the effects of such interventions in the long term.

Investigating the Relationship between Iranian EFL Teachers' Empowerment and their Self-Efficacy as a Consequence for their Educational Improvement

INTRODUCTION

Teacher empowerment is thought to improve student learning by fostering teaching quality. Therefore, the purpose of this study is investigating the relationship between empowerment and self-efficacy of Iranian English as Foreign Language teachers.

MATERIALS AND METHODS

The present study is an experimental study; the population of the study includes all the English language teachers of the universities of Ilam, Iran. Among whom by random sampling, the sample which was consisted of 60 teachers were selected. Participants in this study answered the School Participant Empowerment Scale questionnaire (Short and Rinehart, 1992) as the instrument of the study. The Pearson product-moment correlation was computed to determine the relationship between teacher empowerment and teacher self-efficacy.

RESULTS

The results showed that there was a positive correlation between teacher empowerment and their self-efficacy (r = 0.55, P < 0.01) and differences among teachers' self-efficacy is not significant according to age (r = -0.14, P = 0.23).

CONCLUSIONS

Based on the results of the study, empowerment and self-efficacy have interactive relationships; i.e. self-efficacy in teachers leads to empowerment and empowerment in teachers leads to self-efficacy.

The burden of unintentional drowning: global, regional and national estimates of mortality from the Global Burden of Disease 2017 Study

Background

Drowning is a leading cause of injury-related mortality globally. Unintentional drowning (International Classification of Diseases (ICD) 10 codes W65-74 and ICD9 E910) is one of the 30 mutually exclusive and collectively exhaustive causes of injury-related mortality in the Global Burden of Disease (GBD) study. This study’s objective is to describe unintentional drowning using GBD estimates from 1990 to 2017.

Methods

Unintentional drowning from GBD 2017 was estimated for cause-specific mortality and years of life lost (YLLs), age, sex, country, region, Socio-demographic Index (SDI) quintile, and trends from 1990 to 2017. GBD 2017 used standard GBD methods for estimating mortality from drowning.

Results

Globally, unintentional drowning mortality decreased by 44.5% between 1990 and 2017, from 531 956 (uncertainty interval (UI): 484 107 to 572 854) to 295 210 (284 493 to 306 187) deaths. Global age-standardised mortality rates decreased 57.4%, from 9.3 (8.5 to 10.0) in 1990 to 4.0 (3.8 to 4.1) per 100 000 per annum in 2017. Unintentional drowning-associated mortality was generally higher in children, males and in low-SDI to middle-SDI countries. China, India, Pakistan and Bangladesh accounted for 51.2% of all drowning deaths in 2017. Oceania was the region with the highest rate of age-standardised YLLs in 2017, with 45 434 (40 850 to 50 539) YLLs per 100 000 across both sexes.

Conclusions

There has been a decline in global drowning rates. This study shows that the decline was not consistent across countries. The results reinforce the need for continued and improved policy, prevention and research efforts, with a focus on low- and middle-income countries.

Relationship between aggression and individual resilience with the mediating role of spirituality in academic students - A path analysis

BACKGROUND

The importance of spirituality and spiritual growth in humans has been increasingly taken to attention by psychologists and mental health professionals. In this study, we aimed to investigate the relationship between the tendency to aggression and individual resilience also considering the role of mediator of spirituality in academic students by path analysis.

MATERIALS AND METHODS

A cross-sectional study was conducted using structural equation method (SEM). The target population consisted all of undergraduate academic students in Ilam, Iran University of Applied Sciences, in 2018. Participants included 200 people whom were selected by stratified random sampling. Data collection tools were demographic, Buss and Perry aggression, spirituality assessment, and resiliency of Connor and Davidson questionnaire. In this study, bivariate analysis was used to determine the directionality correlation between the study variables.

RESULTS

The results showed that there was a significant and positive correlation between spirituality and resilience (r = 154% r = 83%). Furthermore, there was a negative and nonsignificant relationship between aggression with resiliency (r = -122% P = 101). In addition, there was no significant correlation between the aggression and spirituality (r = 0.05%, P = 0.942). The results of SEM showed that spirituality and aggression can predict about 20% of the variations in the degree of resilience in academic students. Accordingly, the results of SEM spirituality in an indirect path reduce the aggression and thus increase the resilience (r = 0.102).

CONCLUSION

The results of this study showed the effect of spirituality on increasing the level of resilience and also positive mediator role of spirituality between aggression and resiliency.

Quantifying risks and interventions that have affected the burden of diarrhoea among children younger than 5 years: an analysis of the Global Burden of Disease Study 2017

BACKGROUND

Many countries have shown marked declines in diarrhoeal disease mortality among children younger than 5 years. With this analysis, we provide updated results on diarrhoeal disease mortality among children younger than 5 years from the Global Burden of Diseases, Injuries, and Risk Factors Study 2017 (GBD 2017) and use the study's comparative risk assessment to quantify trends and effects of risk factors, interventions, and broader sociodemographic development on mortality changes in 195 countries and territories from 1990 to 2017.

METHODS

This analysis for GBD 2017 had three main components. Diarrhoea mortality was modelled using vital registration data, demographic surveillance data, and verbal autopsy data in a predictive, Bayesian, ensemble modelling tool; and the attribution of risk factors and interventions for diarrhoea were modelled in a counterfactual framework that combines modelled population-level prevalence of the exposure to each risk or intervention with the relative risk of diarrhoea given exposure to that factor. We assessed the relative and absolute change in diarrhoea mortality rate between 1990 and 2017, and used the change in risk factor exposure and sociodemographic status to explain differences in the trends of diarrhoea mortality among children younger than 5 years.

FINDINGS

Diarrhoea was responsible for an estimated 533 768 deaths (95% uncertainty interval 477 162-593 145) among children younger than 5 years globally in 2017, a rate of 78·4 deaths (70·1-87·1) per 100 000 children. The diarrhoea mortality rate ranged between countries by over 685 deaths per 100 000 children. Diarrhoea mortality per 100 000 globally decreased by 69·6% (63·1-74·6) between 1990 and 2017. Among the risk factors considered in this study, those responsible for the largest declines in the diarrhoea mortality rate were reduction in exposure to unsafe sanitation (13·3% decrease, 11·2-15·5), childhood wasting (9·9% decrease, 9·6-10·2), and low use of oral rehydration solution (6·9% decrease, 4·8-8·4).

INTERPRETATION

Diarrhoea mortality has declined substantially since 1990, although there are variations by country. Improvements in sociodemographic indicators might explain some of these trends, but changes in exposure to risk factors-particularly unsafe sanitation, childhood growth failure, and low use of oral rehydration solution-appear to be related to the relative and absolute rates of decline in diarrhoea mortality. Although the most effective interventions might vary by country or region, identifying and scaling up the interventions aimed at preventing and protecting against diarrhoea that have already reduced diarrhoea mortality could further avert many thousands of deaths due to this illness.

Socioeconomic Inequality in Self-immolation, between Genders; Oaxaca-Blinder Decomposition, Results of Registration-Based Suicide Data

Objective:

To assess the important socio-demographic inequalities in self-immolation in between genders.

Methods:

A cross-sectional study, 2011 to 2016, was conducted. A total of 540 completed suicides were recruited to the study. Data were collected by systematic registration suicide data (SRSD) and Legal Medicine Organization (LMO). The concentration index (CI) was used to determine the inequality. The inequality line was decomposed to find out the main sources of inequality in self-immolation between genders by Oaxaca-Blinder approach.

Results:

The mean ratio of self-immolation was 21.8% among completed suicides. The decreasing trend was found in self-immolations during 2011-2016 (z = -2.07, p = 0.039), the mean rate in six years, was 2.98 per 100.000 populations. Unemployment −.043 (−.07, −0.01), married subject’s −.016 (−.03, −0.00) and low educational level −.005 (−.01, −0.00) were the main inequality source in females compared to males.

Conclusion:

Our results suggest that despite the incidence decreasing in self-immolation within 6 years of study period, the inequality was detected in self-immolation. The main socio-demographics in inequalities were lower educational level, married persons and unemployment that prevention programs should be more concentrated in females to a decrease of inequality in self-immolation.

Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2017: A Systematic Analysis for the Global Burden of Disease Study

Importance

Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.

Objective

To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning.

Evidence Review

We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence.

Findings

In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs).

Conclusions and Relevance

The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

Global, regional, and national incidence, prevalence, and mortality of HIV, 1980-2017, and forecasts to 2030, for 195 countries and territories: a systematic analysis for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017

BACKGROUND

Understanding the patterns of HIV/AIDS epidemics is crucial to tracking and monitoring the progress of prevention and control efforts in countries. We provide a comprehensive assessment of the levels and trends of HIV/AIDS incidence, prevalence, mortality, and coverage of antiretroviral therapy (ART) for 1980-2017 and forecast these estimates to 2030 for 195 countries and territories.

METHODS

We determined a modelling strategy for each country on the basis of the availability and quality of data. For countries and territories with data from population-based seroprevalence surveys or antenatal care clinics, we estimated prevalence and incidence using an open-source version of the Estimation and Projection Package-a natural history model originally developed by the UNAIDS Reference Group on Estimates, Modelling, and Projections. For countries with cause-specific vital registration data, we corrected data for garbage coding (ie, deaths coded to an intermediate, immediate, or poorly defined cause) and HIV misclassification. We developed a process of cohort incidence bias adjustment to use information on survival and deaths recorded in vital registration to back-calculate HIV incidence. For countries without any representative data on HIV, we produced incidence estimates by pulling information from observed bias in the geographical region. We used a re-coded version of the Spectrum model (a cohort component model that uses rates of disease progression and HIV mortality on and off ART) to produce age-sex-specific incidence, prevalence, and mortality, and treatment coverage results for all countries, and forecast these measures to 2030 using Spectrum with inputs that were extended on the basis of past trends in treatment scale-up and new infections.

FINDINGS

Global HIV mortality peaked in 2006 with 1·95 million deaths (95% uncertainty interval 1·87-2·04) and has since decreased to 0·95 million deaths (0·91-1·01) in 2017. New cases of HIV globally peaked in 1999 (3·16 million, 2·79-3·67) and since then have gradually decreased to 1·94 million (1·63-2·29) in 2017. These trends, along with ART scale-up, have globally resulted in increased prevalence, with 36·8 million (34·8-39·2) people living with HIV in 2017. Prevalence of HIV was highest in southern sub-Saharan Africa in 2017, and countries in the region had ART coverage ranging from 65·7% in Lesotho to 85·7% in eSwatini. Our forecasts showed that 54 countries will meet the UNAIDS target of 81% ART coverage by 2020 and 12 countries are on track to meet 90% ART coverage by 2030. Forecasted results estimate that few countries will meet the UNAIDS 2020 and 2030 mortality and incidence targets.

INTERPRETATION

Despite progress in reducing HIV-related mortality over the past decade, slow decreases in incidence, combined with the current context of stagnated funding for related interventions, mean that many countries are not on track to reach the 2020 and 2030 global targets for reduction in incidence and mortality. With a growing population of people living with HIV, it will continue to be a major threat to public health for years to come. The pace of progress needs to be hastened by continuing to expand access to ART and increasing investments in proven HIV prevention initiatives that can be scaled up to have population-level impact.

Investigation the relationship between internet dependence with anxiety and educational performance of high school students

BACKGROUND

Internet is one of the most advanced modern communication technologies. Despite the positive uses of internet, the existence of extreme behaviors and its harmful consequences has attracted the attention of all. The aim of this study was to determine the relationship between internet addiction with anxiety and educational performance.

MATERIALS AND METHODS

This research is a descriptive correlative study. The statistical population of the study includes a total number of 4401 female students in the high school in the city of Ilam-Iran in the academic year of 2017-2018. The sample size includes353 students estimated using Cochran's formula. They were selected by random cluster sampling. For data collection, the Young's Internet Dependency Questionnaire, Academic Performance Inventory, and Marc et al., anxiety Scale were used. Data were analyzed at the significant level of α = 0.05.

RESULTS

The results showed a positive and significant correlation between internet dependency and students' anxiety (P < 0.01). There is also a negative and significant correlation between internet dependency and academic performance of students (P < 0.01), and also a negative and significant correlation between anxiety and educational performance of students (P < 0.01).

CONCLUSION

On the one hand, the results indicate a high prevalence of internet dependency and its significant relationship with anxiety and academic performance in students, and on the other hand, the negative effect of internet dependency on the students' educational performance. Therefore, it is necessary to design some intervention programs to prevent harm to students who are increasingly interacting with internet. In addition, raising the level of the students' awareness on the complications of internet addiction and the proper use of the internet seems to be necessary.

Mapping 123 million neonatal, infant and child deaths between 2000 and 2017

Since 2000, many countries have achieved considerable success in improving child survival, but localized progress remains unclear. To inform efforts towards United Nations Sustainable Development Goal 3.2-to end preventable child deaths by 2030-we need consistently estimated data at the subnational level regarding child mortality rates and trends. Here we quantified, for the period 2000-2017, the subnational variation in mortality rates and number of deaths of neonates, infants and children under 5 years of age within 99 low- and middle-income countries using a geostatistical survival model. We estimated that 32% of children under 5 in these countries lived in districts that had attained rates of 25 or fewer child deaths per 1,000 live births by 2017, and that 58% of child deaths between 2000 and 2017 in these countries could have been averted in the absence of geographical inequality. This study enables the identification of high-mortality clusters, patterns of progress and geographical inequalities to inform appropriate investments and implementations that will help to improve the health of all populations.

The effectiveness of an intervention program -barton intervention program- on reading fluency of Iranian students with dyslexia

BACKGROUND

Difficulty with reading fluency has been increasingly acknowledged as a significant aspect of reading disabilities which is called dyslexia. To investigate this important issue, this research aims to examine the impact of an intervention program on reading fluency of dyslexic students.

MATERIALS AND METHODS

The research is an experimental one. The population of the study included all the second- and third-grade male and female students in the city of Ilam, Iran, among whom 68 students were recognized to be dyslexic using a screening inventory reading test (IRT) developed by Shafiei et al., in 2009, they were selected using purposeful sampling method. The students were equally divided and assigned into a control and an experimental group. The experimental group received the Barton intervention program for 10 weeks. The reading fluency test was administered for the measurement of reading fluency in pre- and post-tests. Data were analyzed using descriptive statistics (mean and standard deviation) and paired t-test.

RESULTS

The analysis of the finding through t-test found a statistically significant difference between the control and experimental groups after the intervention program at P < 0.01.

CONCLUSIONS

The results revealed that the students who received the intervention program of the experimental group were improved in terms of their reading fluency.

The role of socio-economic inequality in the prevalence of hypertension in adults

Introduction: The large portion of burden of diseases, especially in the developing countries is attributed to hypertension. Identification of the potential risk factors of hypertension is essential for disease management. In this study we investigated the role of socio-economic inequality in the prevalence of hypertension in Ilam Province. Methods: Totally, 690 individuals aged over 15 were enrolled in this cross-sectional study, through systematic random sampling from March 1 to October 30, 2017. Socio-economic status (SES) score was calculated by 7 variables including; age, sex, job, marital status, educational level, and economic status, residency, then, it was divided to five levels. Concentration index was used to estimate the inequality in hypertension. To estimate the percentage contribution in final step elasticity divided to concentration index for each contributor and contributions to inequality is estimated. Results: The concentration index for hypertension was -0.154 95% CI (-0.02, -0.23), therefore hypertension was more prevalent in lower socioeconomic groups. The important socioeconomic contributors in inequality were job (P=0.008), educational level (P=0.005), and SES (P=0.003). According to concentration index decomposition, the main sources of inequality in hypertension were job (15%), educational level (18%), and SES (21%), respectively. Conclusion: Hypertension is more prevalent in lower SES groups and the job, education, and SES are important contributory factors of inequality. One substantial key point to achieve an effectiveness approach to deal with chronic diseases might be building partnership with disadvantaged populations.

Past, present, and future of global health financing: a review of development assistance, government, out-of-pocket, and other private spending on health for 195 countries, 1995-2050

BACKGROUND

Comprehensive and comparable estimates of health spending in each country are a key input for health policy and planning, and are necessary to support the achievement of national and international health goals. Previous studies have tracked past and projected future health spending until 2040 and shown that, with economic development, countries tend to spend more on health per capita, with a decreasing share of spending from development assistance and out-of-pocket sources. We aimed to characterise the past, present, and predicted future of global health spending, with an emphasis on equity in spending across countries.

METHODS

We estimated domestic health spending for 195 countries and territories from 1995 to 2016, split into three categories-government, out-of-pocket, and prepaid private health spending-and estimated development assistance for health (DAH) from 1990 to 2018. We estimated future scenarios of health spending using an ensemble of linear mixed-effects models with time series specifications to project domestic health spending from 2017 through 2050 and DAH from 2019 through 2050. Data were extracted from a broad set of sources tracking health spending and revenue, and were standardised and converted to inflation-adjusted 2018 US dollars. Incomplete or low-quality data were modelled and uncertainty was estimated, leading to a complete data series of total, government, prepaid private, and out-of-pocket health spending, and DAH. Estimates are reported in 2018 US dollars, 2018 purchasing-power parity-adjusted dollars, and as a percentage of gross domestic product. We used demographic decomposition methods to assess a set of factors associated with changes in government health spending between 1995 and 2016 and to examine evidence to support the theory of the health financing transition. We projected two alternative future scenarios based on higher government health spending to assess the potential ability of governments to generate more resources for health.

FINDINGS

Between 1995 and 2016, health spending grew at a rate of 4·00% (95% uncertainty interval 3·89-4·12) annually, although it grew slower in per capita terms (2·72% [2·61-2·84]) and increased by less than $1 per capita over this period in 22 of 195 countries. The highest annual growth rates in per capita health spending were observed in upper-middle-income countries (5·55% [5·18-5·95]), mainly due to growth in government health spending, and in lower-middle-income countries (3·71% [3·10-4·34]), mainly from DAH. Health spending globally reached $8·0 trillion (7·8-8·1) in 2016 (comprising 8·6% [8·4-8·7] of the global economy and $10·3 trillion [10·1-10·6] in purchasing-power parity-adjusted dollars), with a per capita spending of US$5252 (5184-5319) in high-income countries, $491 (461-524) in upper-middle-income countries, $81 (74-89) in lower-middle-income countries, and $40 (38-43) in low-income countries. In 2016, 0·4% (0·3-0·4) of health spending globally was in low-income countries, despite these countries comprising 10·0% of the global population. In 2018, the largest proportion of DAH targeted HIV/AIDS ($9·5 billion, 24·3% of total DAH), although spending on other infectious diseases (excluding tuberculosis and malaria) grew fastest from 2010 to 2018 (6·27% per year). The leading sources of DAH were the USA and private philanthropy (excluding corporate donations and the Bill & Melinda Gates Foundation). For the first time, we included estimates of China's contribution to DAH ($644·7 million in 2018). Globally, health spending is projected to increase to $15·0 trillion (14·0-16·0) by 2050 (reaching 9·4% [7·6-11·3] of the global economy and $21·3 trillion [19·8-23·1] in purchasing-power parity-adjusted dollars), but at a lower growth rate of 1·84% (1·68-2·02) annually, and with continuing disparities in spending between countries. In 2050, we estimate that 0·6% (0·6-0·7) of health spending will occur in currently low-income countries, despite these countries comprising an estimated 15·7% of the global population by 2050. The ratio between per capita health spending in high-income and low-income countries was 130·2 (122·9-136·9) in 2016 and is projected to remain at similar levels in 2050 (125·9 [113·7-138·1]). The decomposition analysis identified governments' increased prioritisation of the health sector and economic development as the strongest factors associated with increases in government health spending globally. Future government health spending scenarios suggest that, with greater prioritisation of the health sector and increased government spending, health spending per capita could more than double, with greater impacts in countries that currently have the lowest levels of government health spending.

INTERPRETATION

Financing for global health has increased steadily over the past two decades and is projected to continue increasing in the future, although at a slower pace of growth and with persistent disparities in per-capita health spending between countries. Out-of-pocket spending is projected to remain substantial outside of high-income countries. Many low-income countries are expected to remain dependent on development assistance, although with greater government spending, larger investments in health are feasible. In the absence of sustained new investments in health, increasing efficiency in health spending is essential to meet global health targets.

Investigating the relationship between conscientiousness and self-compassion with marital satisfaction among Iranian married employees

BACKGROUND

Marital satisfaction, conscientiousness, and self-compassion are necessary for successful and lasting marriages. Therefore, the purpose of this study was to investigate the relationship between marital satisfaction, conscientiousness, and self-compassion among married employees of Shahid Mostafa Khomeini Hospital in the city of Ilam in 2017.

METHODOLOGY

This study is a descriptive research with a correlation design. The research population included all 260 married employees of Mostafa Khomeini (I) Hospital in the city of Ilam, among which 150 were selected using simple random sampling. Data were collected using three questionnaires of conscientiousness, self-compassions, and marital satisfaction. Data were analyzed using Pearson correlation and multivariate regression.

RESULTS

The research results revealed a positive and significant relationship between conscientiousness and marital satisfaction (P = 0.028 and r = 0.187) and a positive and significant relationship between self-compassion and marital satisfaction (P = 0.000 and r = 0.185). Both conscientiousness and self-compassion variables could predict 51% of the variance of marital satisfaction among married employees.

CONCLUSIONS

Given the research results, it could be stated that people who have self-compassion and have a high level of conscientiousness make much effort for their improvement and resolving their committed mistakes. For this reason, they have high motivation to maintain marital relationships.

The association between body mass index and the risk of endometriosis: A meta-analysis

Background:

Many epidemiologic studies have been conducted to assess factors that were associated to endometriosis, but there is no consistency in results. Therefore, we conducted this meta-analysis to investigate the association between body mass index and the risk of endometriosis.

Methods:

In this meta-analysis, relevant studies that published in major international electronic bibliographic databases of PubMed, Scopus and Web of Science were systematically searched during November 2017. The Begg and Egger’s test was used to investigate publication bias in included studies. The Q-statistic and I2 tests were carried out for measuring heterogeneity. The random-effects model was conducted to obtain pooled odds ratio.

Results:

Our results showed a direct association between underweight and endometriosis in woman (odds ratio = 1.41, 95% confidence interval = 1.16–1.66), so underweight woman had 41% higher chance for endometriosis. However, we did not find linear association between overweight and endometriosis (odds ratio = 0.95; 95% confidence interval: 0.72–1.18) and obesity and endometriosis (odds ratio = 0.88; 95% confidence interval: 0.54–1.21), respectively.

Conclusions:

Our results suggested that underweight was a risk factor for the endometriosis, while overweight and obesity were not protective factors for endometriosis.

Angiogenic factors and the risk of preeclampsia: A systematic review and meta-analysis

Background

The etiological nature of preeclampsia is heterogeneous. The use of biomarkers indices in early pregnancy helps to have appropriate stratification of pregnancies into high- and low risk for the purpose of choosing timely interventions.

Objective

The aim of this systematic review was to determine the pathogenic role of soluble soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) in the prediction of preeclampsia in women.

Materials and Methods

We performed a systematic search of the international databases including PubMed, Scopus, and Web of Science until August 2017. The quality of included studies was assessed using the Newcastle-Ottawa Scale. The primary outcome in this review was preeclampsia. The statistical heterogeneity was assessed using the X2 test and quantified by I2. Pooled effects size was obtained by random effects model. Subgroup analyses were also carried out.

Results

Totally, 284 records were identified in the initial search and 15 records were finally included in the meta-analysis. The pooled odds ratios (ORs) for the association between the high level of sFlt-1 and low level of PlGF and subsequent development of preeclampsia among women were 5.20 (95% CI: 1.24–9.16) and 2.53 (95% CI: 1.33–3.75), respectively. The mean difference for sFlt-1 and PlGF in women with preeclampsia compared to controls was 1.15 (95% CI: 0.43–1.86) and –0.94 (95% CI: –1.37–0.52), respectively.

Conclusion

According to the results from this meta-analysis, increased levels of sFlt-1 and reduced levels of PlGF predict the subsequent development of preeclampsia.

5-year survival rates based on the type of leukemia in Iran, a Meta-analysis

Background:

According to epidemiological studies, leukemia is among the five most common cancers in Iran. Keeping efforts to estimate survival is critical to monitoring and improving patients’ quality of life with leukemia. The purpose of this study was to evaluate the 5-year survival rate of leukemia patients in Iran using meta-analysis method.

Methods:

This meta-analysis was carried out according to studies that adhere to inclusion and exclusion criteria during enrolment. The valid Iranian databases included: Medex, Magiran, SID, and Medlib, along with international data bases, namely, Scopus, Pubmed, and ISI were searched to find relevant articles. After determining the heterogeneity between studies, the random effects models were used to estimate pooled survival in leukemia patients.

Results:

In total, 18 studies involving 2517 participants were included in this meta-analysis. The pooled 5-year survival rate was 0.56 % (95% CI, 0.54 to 0.58). According to types AML and ALL, the 5-year survival rates in Iran were 35.0 % (95% CI: 32.0-38.0) and 57.0 % (95% CI: 54.0-60.0), respectively.

Conclusion:

Based on our findings, slightly less than 50% of leukemia deaths happened in the first 5 years after diagnosis, which is lower than the global average.

The relationship between smoking and dysmenorrhea: A meta-analysis

Many studies have investigated the potential association between smoking and dysmenorrhea. However, results from such studies have been inconsistent. In this study, we assessed the association between smoking and dysmenorrhea by meta-analysis. We performed a systematic search of the international databases, including PubMed, Scopus, Web of Science, EBSCO and Google Scholar by the MeSH heading and/or additional terms to obtain relevant studies published from 1990 until 2017. I² statistics were used to assess heterogeneity. Pooled effects size was obtained using a random effects model. Subgroup analyses were also conducted. Data were analyzed through Stata software version 12 (Stata Corp, College Station, TX, USA). A total of fourteen studies were included in meta-analysis. A significant positive association was observed between current smoking and dysmenorrhea in both the unadjusted (odds ratio [OR] = 1.60; 95 percent confidence interval [CI]: 1.35, 1.85) and adjusted models (AOR = 1.44; 95 percent CI: 1.18, 1.69). Also, the association between current smoking and primary dysmenorrhea was significant only in the unadjusted model (OR = 1.53; 95 percent CI: 1.21, 1.85). The pooled effects size showed a significant association between smoking and dysmenorrhea in the fourteen eligible studies. This provides a new approach for prevention from dysmenorrhea in females for policymakers.

The Relationship Between Human Development Index and Its Components with Thyroid Cancer Incidence and Mortality: Using the Decomposition Approach

BACKGROUND

The link between age specific-rates of thyroid cancer (TC) and human development index (HDI) and also its components can be a new direction for planning by policy makers.

OBJECTIVES

This study aimed at identifying the relationship between TC rates by gender, and HDI and its components in different regions of the world.

METHODS

An ecological study was conducted; the data was obtained from the GLOBOCAN project in 2012. Inequality in TC estimates (age-specific incidence and mortality rates), according to the HDI and its components was calculated. Concentration index (CI) was used to estimate inequality and CI was decomposed to determine contribution of HDI and its components in inequality.

RESULTS

The inequality index (CI) was 0.29 (95% CI: 0.21 - 0.38) and -0.15 (95% CI: -0.23 - 0.06) for incidence and mortality of TC by HDI, respectively. The important contributors in inequality for incidence rates of TC were life expectancy at birth (0.30), mean years of schooling (0.26), and expected years of schooling (0.18). The important contributors in inequality of mortality rates were mean years of schooling (0.19), expected years of schooling (0.17), and urbanization (0.17).

CONCLUSIONS

According to the findings of this study, global inequalities exist in the TC incidence and mortality rates; incidence rates of TC are more concentrated in countries with high HDI, yet inequality index showed that deaths occurred more in disadvantaged countries.

Trends of Suicide Attempts and Completed Suicide in Ilam Province of Iran; A Demographic Analysis Study

Suicide is a serious public health concern in the world. Epidemiologists are considered the mainstay of the management of problem. The purpose of this study was to investigate the trend of suicide (attempts and completed) by age and gender in a 6-year time period and to compare the suicide rates between in age and gender groups in Ilam. In this cross-sectional study, a total of number of suicidal attempts during a 6-year period from 2011 to 2016 were recorded. The data were derived from the systematic registration suicide data (SRSD) which collects official statistics from the Ilam University of Medical Sciences. Suicide rate in period of the study in men was reported to be 24.0 in 2011 to 17.9 in 2016 per 100,000 populations; also this rate in women was between 16.2 in 2011 to 7.3 in 2016 per 100,000 populations. Trend analysis revealed a decreasing trend (r= -0.82, p=.043), in attempts, as well as completed suicides (r= -0.53, p=.048). The current data demonstrated a decreasing trend in both attempts and completed suicide rates from 2011 to 2016. Also we found that the rate of completed suicide in all age groups were higher in men compared to women.

Epidemiologic Aspects of Overall Injuries in Hamadan Province; A Six-Year Registry-Based Analysis

Objective:

To investigate the epidemiological aspects of all-cause injuries in Hamadan province during a 6-year period.

Methods:

We conducted a cross-sectional study on injured subjects admitted to private or governmental hospitals in Hamadan province during March 2009 to March 2015. The epidemiological characteristics were retrieved from a registry-based system including gender, residency, injury mechanism and date of injury occurrence, outcome of hospitalization (full recovery/disability/death).

Results:

Totally, 135,925 hospitalized injured cases were recorded. The majority of cases were male (72.6%) and were occurred in urban areas (60%), about 40% of patients were in 20-34 years’ age group, and the highest proportion (30.13%) of injuries occurred in summer. Logistic regression showed that the odds of disability vs. recovery was significantly higher in rural areas [Adjusted odds ratio (AOR) =3.42] and the odds of death vs. recovery was higher among male gender (AOR=1.46). In addition, comparing to the 0-4-year age-group, odds of death were significantly higher in middle aged and elderly victims.  

Conclusion:

Our findings showed that middle age groups, male gender and urban area increase the odds of death. Injured males and old age subjects had the highest odds of death and out of residential area injuries were common cause of leading death injuries.

Prevalence of hepatitis C virus infection among high-risk groups in Iran: a systematic review and meta-analysis

OBJECTIVES

Determination of the true burden of hepatitis C virus (HCV) infection among high-risk groups relies heavily on occurrence measures such as prevalence, which are vital for implementation of preventive action plans. Nevertheless, up-to-date data on the prevalence of HCV infection remain scarce in Iran. This study aimed to review the relevant literature systematically and determine the pooled prevalence of HCV infection among high-risk groups in Iran.

STUDY DESIGN

Systematic review & meta-analysis.

METHODS

In 2016, electronic scientific databases including PubMed, Scopus, Web of Science and local databases were searched using a detailed search strategy with language restricted to English and Farsi. The reference lists of the studies included in this review were also screened. Data were reviewed and extracted independently by two authors. A random effects model was used to estimate the pooled prevalence. Sources of heterogeneity among the studies were determined using subgroup analysis and meta-regression.

RESULTS

In total, 1817 records were identified in the initial search, and 46 records were included in the meta-analysis. The overall prevalence of HCV among high-risk groups was 32.3%. The prevalence was 41.3% in injection drug users (IDUs), 22.9% in prisoners, 16.2% in drug-dependent individuals and 24.6% in drug-dependent prisoners. Subgroup and meta-regression analyses revealed that geographical location and year of publication were the probable sources of heterogeneity.

CONCLUSION

This meta-analysis found a high prevalence of HCV among high-risk groups in Iran, particularly among IDUs. There is a need for prevention strategies to reduce the burden of HCV infection among high-risk groups, particularly IDUs.

Epidemiology of Animal Bites and Associated Factors with Delay in Post-Exposure Prophylaxis; A Cross-Sectional Study

Objective:

To address the epidemiology of animal bites and associated factors with delay in post-exposure prophylaxis (PEP) in Nahvand district, western Iran.

Methods:

Data were obtained from Rabies Treatment Center (RTC) in Nahavan district from March 2015 to March 2017. All of referred cases to RTC include 1448 cases of animal bites using the census method were recruited. Epidemiological profile of participants was demonstrated using descriptive statistics and determinants of PEP was addressed by logistic regression model.

Results:

The majority of victims were males 1167(80.5%). superficial bites were more prevalent than deep status injuries (1145(79.0%) VS. 303(20.9%)). The biting rate differed according to season in the period of the study (p<0.001). Cases who experienced animal biting in the autumn was more likely to refer timely for PEP than cases in spring season (OR, 0.39; 95% CI: 0.26 - 0.59, p<0.001).

Conclusion:

Our findings addressed the pattern of potential delays in PEP including the role of season. Local authorities of Nahavand district should considered preventive activities and educational interventions to reduce animal biting and provide timely prophylaxis.

Socio-demographic factors associated with choosing violent methods of suicide, 2011-2016, Ilam province

BACKGROUND

In new strategies towards of suicide prevention the best approach currently is based on specific method had specific risk factors. Therefore in this study we aimed to find out the association between socio-demographic factors and methods in completed suicide, 2011-2016, Ilam province.

METHODS

A cross-sectional study, 2011-2016, was conducted. A total of 540 completed suicides were recruited to the study. Data were collected by systematic registration suicide data (SRSD) and Legal Medicine Organization (LMO). After performs of descriptive statistics, to analysis of effects of each independent variable to the methods Multinomial Logistic Regression (MLR) was used, also adjusted odds ratio (AOR) was used to reporting of associations.

RESULTS

According to the result (55.8%) of deaths were occurred by hanging and self-immolation also a majority of suicides were occurred in females (60%). The important methods in males and females were hanging (70.6%) and self-immolation (72.8%), respectively. The self-immolation vs. others was significantly higher in cases that have mental disorders (AOR) = 2.05, 95% CI: 1.11, 3.78); also in cases with financial problem (AOR) = 2.70, 95% CI: 1.28, 5.71).

CONCLUSION

According to the finding age groups, gender, marital status, residence, and mental disorders are the important risk factors that effects on choosing of methods. Therefore consideration of this excess risk by this mentioned factors in prevention programs can be reducing the risk of death from suicide in society.
