Prevalence of stress urinary incontinence and urge urinary incontinence in multiples sclerosis patients: a systematic review and meta-analysis.

Urinary incontinence (UI), encompassing stress urinary incontinence (SUI) and urge urinary incontinence (UUI), is a prevalent and debilitating condition in patients with multiple sclerosis (MS), profoundly impacting their quality of life. This systematic review and meta-analysis aimed to elucidate the worldwide prevalence rates of SUI and UUI among MS patients. This study was conducted by examining observational studies published between 2000 and 2023. An exhaustive literature search was conducted across databases such as PubMed, MEDLINE, Web of Science, Scopus, ProQuest, and Google Scholar. The Meta-prop method facilitated pooled prevalence estimation of UUI and SUI, while Egger tests assessed publication bias. In total, 27 studies with 15,052 participants were included in the meta-analysis. The findings revealed a high random effect pooled prevalence of UUI at 41.02% (95% Confidence Interval [CI]: 30.57-51.89; I2 = 99%, p < 0.001) and SUI at 25.67% (95% CI: 19.30-32.58%; I2 = 94.9%, P < 0.001). Additionally, the pooled prevalence of mixed urinary incontinence (MUI) was reported at 18.81% (95% CI: 7.55-33.48; I2:95.44%, p < 0.001). The high heterogeneity observed suggests variable prevalence across populations and highlights the intricate nature of UI in MS. These findings underscore the critical need for dedicated supportive, therapeutic, and rehabilitative interventions to manage this common complaint in MS patients effectively.

The quality of life of men experiencing infertility: a systematic review.

BACKGROUND: Men experiencing infertility encounter numerous problems at the individual, family, and social levels as well as quality of life (QOL). This study was designed to investigate the QOL of men experiencing infertility through a systematic review. MATERIALS AND METHODS: This systematic review was conducted without any time limitation (Retrieval date: July 1, 2023) in international databases such as Scopus, Web of Science, PubMed, and Google Scholar. The search was performed by two reviewers separately using keywords such as QOL, infertility, and men. Studies were selected based on inclusion and exclusion criteria. The quality of the articles were evaluated based on the Newcastle-Ottawa Scale. In the initial search, 308 studies were reviewed, and after removing duplicates and checking the title and abstract, the full text of 87 studies were evaluated. RESULTS: Finally, 24 studies were included in the final review based on the research objectives. Based on the results, men's QOL scores in different studies varied from 55.15 ± 13.52 to 91.45 ± 13.66%. Of the total reviewed articles, the lowest and highest scores were related to mental health problems and physical dimensions, respectively. CONCLUSION: The reported findings vary across various studies conducted in different countries. Analysis of the factors affecting these differences is necessary, and it is recommended to design a standard tool for assessing the quality of life of infertile men. Given the importance of the QOL in men experiencing infertility, it is crucial to consider it in the health system. Moreover, a plan should be designed, implemented and evaluated according to each country's contex to improve the quality of life of infertile men.

The design of an Obstetric Telephone Triage Guideline (OTTG): a mixed method study.

BACKGROUND: Clarifying the dimensions and characteristics of obstetric telephone triage is important in improving the quality of services in the health system because researchers can evaluate the effectiveness of treatment, care and diagnostic measures in the form of obstetric telephone triage by developing a guideline. Therefore, this study aimed to design an Obstetric Telephone Triage Guideline (OTTG) using a mixed-method study. METHODS: The present study was carried out using an exploratory sequential mixed method study in two qualitative and quantitative phases. An inductive-deductive approach was also used to determine the concept of obstetric telephone triage. In this respect, a qualitative study and a literature review were used in the inductive and deductive stages, respectively. Moreover, the validity of the developed guideline was confirmed based on experts' opinions and results of the AGREE II tool. RESULTS: The guideline included the items for evaluating the severity of obstetric symptoms at five levels including "critical", "urgent", "less urgent", "no urgent", and "recommendations". The validity of the guideline was approved at 96%, 95%, 97%, 95%, 93%, and 100% for six dimensions of AGREE II including scope and purpose, stakeholder involvement, the rigor of development, clarity of presentation, applicability, and editorial independence, respectively. CONCLUSION: The OTTG is a clinically comprehensive, easy-to-use, practical, and valid tool. This guideline is a standardized tool for evaluating the severity of symptoms and determining the urgency for obstetrics triage services. By using this integrated and uniform guideline, personal biases can be avoided, leading to improved performance and ensuring that patients are not overlooked. Additionally, the use of OTTG promotes independent decision-making and reduces errors in triage decision-making.

APOE and Alzheimer's disease: Pathologic clues from transgenic Drosophila melanogaster.

Alzheimer's disease (AD) is one of the most common forms of neurodegenerative diseases. Apolipoprotein E4 (ApoE4) is the main genetic risk factor in the development of late-onset AD. However, the exact mechanism underlying ApoE4-mediated neurodegeneration remains unclear. We utilized Drosophila melanogaster to examine the neurotoxic effects of various human APOE isoforms when expressed specifically in glial and neural cells. We assessed impacts on mitochondrial dynamics, ER stress, lipid metabolism, and bio-metal ion concentrations in the central nervous system (CNS) of the transgenic flies. Dachshund antibody staining revealed a reduction in the number of Kenyon cells. Behavioral investigations including ethanol tolerance and learning and memory performance demonstrated neuronal dysfunction in APOE4-expressing larvae and adult flies. Transcription level of marf and drp-1 were found to be elevated in APOE4 flies, while atf4, atf6, and xbp-1 s showed down regulation. Enhanced concentrations of triglyceride and cholesterol in the CNS were observed in APOE4 transgenic flies, with especially pronounced effects upon glial-specific expression of the gene. Spectrophotometry of brain homogenate revealed enhanced Fe++ and Zn++ ion levels in conjunction with diminished Cu++ levels upon APOE4 expression. To explore therapeutic strategies, we subjected the flies to heat-shock treatment, aiming to activate heat-shock proteins (HSPs) and assess their potential to mitigate the neurotoxic effects of APOE isoforms. The results showed potential therapeutic benefits for APOE4-expressing flies, hinting at an ability to attenuate memory deterioration. Overall, our findings suggest that APOE4 can alter lipid metabolism, bio metal ion homeostasis, and disrupt the harmonious fission-fusion balance of neuronal and glial mitochondria, ultimately inducing ER stress. These alterations mirror the main clinical manifestations of AD in patients. Therefore, our work underscores the suitability of Drosophila as a fertile model for probing the pathological roles of APOE and furthering our understanding of diverse isoform-specific functions.

Coenzyme Q10 supplementation in burn patients: a double-blind placebo-controlled randomized clinical trial.

BACKGROUND: Burn injuries are important medical problems that, aside from skin damage, cause a systemic response including inflammation, oxidative stress, endocrine disorders, immune response, and hypermetabolic and catabolic responses which affect all the organs in the body. The aim of this study was to determine the effect of coenzyme Q10 (CoQ10) supplementation on inflammation, oxidative stress, and clinical outcomes in burn patients. METHODS: In a double-blind placebo-controlled randomized clinical trial, 60 burn patients were randomly assigned to receive 100 mg CoQ10 three times a day (total 300 mg/day) or a placebo for 10 days. Inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), oxidative stress markers including total antioxidant capacity (TAC), malondialdehyde (MDA) and superoxide dismutase (SOD) activity, fasting blood glucose (FBG), blood urea nitrogen (BUN), creatinine, white blood cells (WBC), and body temperature were assessed as primary outcomes and albumin, prothrombin time (PT), partial thromboplastin time (PTT), international normalized ratio (INR), other hematological parameters, blood pressure, O2 saturation, ICU duration, and 28-mortality rate were assessed as secondary outcomes. RESULTS: Fifty-two participants completed the trial. CRP and ESR levels were not significantly different between CoQ10 and placebo groups at the end of the study (P = 0.550 and P = 0.306, respectively). No significant differences between groups were observed for TAC (P = 0.865), MDA (P = 0.692), and SOD activity (P = 0.633) as well. Administration of CoQ10 resulted in a significant increase in albumin levels compared to placebo (P = 0.031). There was no statistically significant difference between the two groups in other measured outcomes (P > 0.05). CONCLUSION: Results showed that in patients with burn injury, CoQ10 administration had no effect on inflammatory markers and oxidative stress, although serum albumin levels were improved after supplementation. Further studies with albumin as the primary outcome are needed to confirm this finding.

The self-care situation analysis of reproductive-aged women in Tehran: a survey study.

BACKGROUND: Along with a global increase in the prevalence of infectious and non-communicable diseases, self-care with an emphasis on reproductive health Self-care has received special attention. Given the importance of women's health, assessment of their self-care status using a valid and reliable tool seems to be necessary to determine the needs for future women's reproductive health promotion interventions. The present study aimed to assess the women's self-care at reproductive age in Tehran, to determine women's health needs based on global guidelines for women's health. METHODS: This was a descriptive cross-sectional study on 1051 women of reproductive age, living in Tehran. The Subjects were recruited using a multi-stage sampling method. The women completed a socio-demographic and valid and reliable questionnaire to assess their self-care status. The data were analyzed using SPSS 24 and by Pearson, Spearman, ANOVA, and regression tests. RESULTS: The mean score of self-care was 49.57 ± 23.50% in the reproductive-aged women. The lowest scores were related to psychosocial health (32.12 ± 29.93%) and reproductive-sexual health (49.74 ± 27.99%) respectively. There were significant positive correlations between the self-care and women's education level (r = 0.180; p < 0.01), and husband's education level (r = 0.272; p < 0.01), while there was a negative significant correlation between the self-care and the family size (r = - 0.135; p < 0.01). CONCLUSION: The findings showed inadequate self-care among reproductive-aged women in Tehran. The most important challenge in their self-care behaviors was related to psychosocial and reproductive-sexual health. It seems to provide a package for promoting women's self-care in four areas of physical, psychosocial, reproductive-sexual health, and screening tests, with an emphasis on the first two priorities, namely psychosocial and reproductive health necessary in Tehran.

The framework for integrated, people-centered health services was introduced in 2016 by the World Health Organization (WHO) (World Health Organization, Interim report: placing people and communities at the Centre of health services: WHO global strategy on integrated peoplecentred health services 2016-2026: executive summary, 2015). A people-centered approach supports health literacy so that people can take responsibility for their health with evidence-based self-care interventions. When people have agency and autonomy, they can make and enact decisions in all aspects of their lives, including health (World Health Organization, WHO consolidated guideline on self-care interventions for health: sexual and reproductive health and rights: executive summary, 2019). The WHO defines self-care as "the ability of individuals, families, and communities to promote health, prevent disease, maintain health, and to cope with illness and disability with or without the support of a healthcare provider". Self-care allows people to become agents of their health, leading to improved outcomes, especially in the area of sexual and reproductive health where stigma may prevent them from seeking care. Women and girls can identify their own health needs, and effectively manage their health conditions through self-care approaches. The WHO places great emphasis on promoting self-care, especially in women's reproductive-sexual health, and encourages countries to design and implement their programs. Given the diversity of women's self-care needs, this study designed women's self-care assessment tools in two reproductive age groups in 4 dimensions including physical, psychosocial, sexual-reproductive health, and screening tests, based on a review of the valid international guidelines. The results showed that women are practicing only half of self-care and the main challenges were in psychosocial health and sexual-reproductive-health self-care in Tehran. It seems that evidence-based planning is necessary to promote self-care among reproductive-aged women.

Prevalence of depression in infertile men: a systematic review and meta-analysis.

BACKGROUND: Generally, infertile men hide their depression, which can threaten their health and lower their quality of life. Given the role of depression and its impact on people's health, this systematic review and meta-analysis aimed to investigate the prevalence of depression in infertile men. METHODS: This research is a systematic review and meta-analysis based on preferred reporting items for systematic reviews and meta-analyses (PRISMA). Using the keywords of "Depression", "Emotional Depression", "Infertility", "Prevalence", and "Epidemiology", all English language articles were searched in international databases (PubMed, Cochran library, Web of sciences, Scopus, Embase, PsyINFO, and Google scholar) by two reviewers independently and without considering the time limit until September 2022. Title, abstract, full text and quality of each study were evaluated by two reviewers independently using the Newcastle-Ottawa Scale checklist. The results were analyzed using programming language and R software, and I2 test and Egger's Test were used to check heterogeneity and publication bias, respectively. RESULTS: Twenty-two studies were included in the systematic part of this study; and 8 different measurement tools were used to identify depression. Then, based on the possibility of meta-analysis, 18 studies were included in 4 subgroups. Given the heterogeneity of the articles, random effect model was used. The overall prevalence of depression in infertile men was 18.30%. The lowest and highest overall prevalence of depression in men was reported to be 14.04% and 23.63% in the Zung Self-Rating Depression Scale (ZDS) and the Depression Anxiety Stress Scales (DASS) tools, respectively. The overall prevalence of depression among infertile men was reported to be 18.55% and 16.75% using the Beck Depression Inventory (BDI) and the Hospital Anxiety and Depression Scale (HADS) tools, respectively. CONCLUSION: Based on the findings of this study, the significant prevalence of depression in infertile men requires a specific attention and planning. The study revealed varying degrees of depression among infertile men, emphasizing the importance of assessing their mental health, specifically in terms of depression, during infertility treatments as a hidden variable. It is strongly recommended to develop training programs for health service providers to effectively utilize diagnostic tools in this particular field.

Development and validation of the code of ethics for midwives in Iran.

BACKGROUND: Considering ethical issues in midwifery care is essential for improving the quality of health services and the client's satisfaction. This study aimed to develop and validate the code of ethics for Midwives in Iran (ICEM). MATERIALS AND METHODS: This was a mixed sequential study that was performed in three phases including a qualitative study, a review, and the content validity assessment. The first phase was a qualitative study with a content analysis approach. The data were collected by conducting in-depth semi-structured individual interviews with 14 midwifery and ethics experts. The purposive sampling method was used to recruit the participants and sampling continued until data saturation. The data were analyzed using the conventional content analysis described by Graneheim and Lundman. Lincoln and Guba's criteria were used to confirm the trustworthiness of the data. Then, a narrative review of the selected national and international codes of ethics for Midwives was performed to complete the items of the ICEM. For validity assessment, the face and content validity of the items of ICEM was assessed by 15 experts to calculate the content validity ratio (CVR) and index (CVI). RESULTS: Fourteen experts were interviewed in the qualitative phase, and 207 codes were extracted from a content analysis which were categorized into 23 sub-categories and 6 main categories. The extracted codes were considered as the items for ICEM that were completed by a review of the selected national and international code of ethics for Midwives. The content validity and ratio assessment of the items demonstrated an average CVI = 0.92 and CVR = 0.85. Then, the final version of ICEM was developed with 92 items in 6 domains about; 1) "professional Commitments" with 30 items; 2) "providing midwifery services to the client and her companions" with 26 items; 3) "relationship with colleagues" with 11 items; 4) "herself" with 6 items; 5) "education and research" with 8 items; and, 6) "management" with 11 items. CONCLUSION: ICEM was prepared with 92 items in six sections that facilitate its use for midwives who are working in the different fields of care, counseling, education, research, and management. In this new version of the ICEM, the items related to recent social-, scientific, and technical improvements were considered for providing ethical midwifery care.

The effect of probiotics on oxidized LDL levels: A systematic review and meta-analysis of clinical trials.

BACKGROUND: It has been widely reported that the use of probiotics has beneficial effects on the prevention and treatment of a wide range of human diseases. Previous clinical trials have investigated the effect of probiotics on oxLDL, but the results are controversial. OBJECTIVE: This study aimed to conduct a systematic review and meta-analysis of clinical trials to assess the effect of probiotic consumption on oxLDL levels. METHOD: A comprehensive search was conducted in PubMed, ISI Web of Science, and Scopus using the appropriate search strategy. After the screening, seven studies comparing the effects of probiotic consumption with the control were included in the analysis. A random-effects analysis was used to estimate the overall effect size. RESULTS: Probiotic supplementation significantly reduced oxLDL (Hedge's: -1.18; 95% CI:-1.85, -0.52) compared to the control group. Subgroup analysis showed that reduction was greater in the unhealthy group compared to healthy subjects (-2.05 vs. -0.84). The results also showed that probiotic supplementation reduced TC by -14.77 mg/dl (95% CI: -24.46, -5.08), LDL-C by -10.03 mg/dl (95% CI: -16.05, -4.001), LDL-C/HDL-C ratio by -0.37 (95% CI: -0.66, 0.07), and TG by -14.86 mg/dl (95% CI: -23.45, -6.28) but the effects on HDL-C and glucose were not significant. CONCLUSION: In this study, probiotic supplementation was found to improve oxLDL concentrations and have favorable effects on lipid profiles, but no significant positive effect on HDL-C and glucose was reported. However, the findings should be interpreted with caution due to the low number of included studies.

Design, implementation, and validation of an application for childbirth preparation classes to improve the performance of midwifery students: Study protocol.

BACKGROUND: Childbirth preparation classes are incredibly useful for midwifery students as future medical personnel. Nowadays, given the outbreak of Covid-19 pandemic and as mobile applications are extensively welcomed, virtual space can be used for education in the area of childbirth preparation classes. Given the lack of an application for childbirth preparation classes, this study will be conducted to design, implement and validate such an application to improve the performance of midwifery students in the areas of pregnancy and safe delivery. MATERIALS AND METHODS: The present study will be conducted in three phases. In the first phase, content will be provided to Information Technology experts based on the content of the national guidelines for physiological delivery in Iran, and the application will be designed and validated for the use of midwifery students, then develop app for other medical students, midwives and physicians. In the second phase, the assessment will be based on Kirkpatrick's model. In the third stage, develop app for other medical students, midwives and physicians based on the results of the first and second phase. SPSS version 17 will be used in this phase for analysis of data through descriptive and analytical tests. CONCLUSION: Owing to the expansion of virtual space and the outbreak of Covid-19 pandemic, design, validation, and evaluation of an application for childbirth preparation classes is an exceptionally significant necessity which contributes to the process of educating midwifery students.

The efficacy of dietary approaches to stop hypertension (DASH) diet on lipid profile: A systematic review and meta-analysis of clinical controlled trials.

BACKGROUND: Dyslipidemia is considered a causal risk factor for coronary heart disease and stroke. Plant-based diets such as dietary approaches to stop hypertension (DASH) have beneficial effects on cardiovascular health. This meta-analysis was conducted to assess the effects of the DASH diet on lipid profiles based on clinical controlled trials. METHODS: An inclusive online search was performed in medical databases including Web of Science, PubMed, Scopus, and Google Scholar up to October 2021 to identify trials assessing the effect of the DASH diet on lipid profiles. RESULTS: Seventeen studies comprising 2218 individuals were included in this meta-analysis. In comparison to the control group, following the DASH diet resulted in a significant reduction in serum triglycerides (WMD: -5.539 mg/dl; 95% CI: -8.806, -2.272) and low-density lipoprotein cholesterol (WMD: -6.387 mg/dl; 95% CI: -12.272, -0.501). However, DASH diet could not reduce serum total cholesterol (WMD: -5.793 mg/dl; 95% CI: -12.84, 1.254), high-density lipoprotein cholesterol (WMD: 0.631 mg/dl; 95% CI: -0.749, 2.011), and total cholesterol/high-density lipoprotein cholesterol ratio (WMD: -0.11 mg/dl; 95% CI: -0.27, 0.05). CONCLUSION: Findings of this meta-analysis showed that following the DASH diet had beneficial effects on serum triglycerides and low-density lipoprotein cholesterol, however, it had no effect on serum total cholesterol and high-density lipoprotein cholesterol levels. Based on these results, the DASH diet can be considered a strategy for the prevention and complementary management of dyslipidemia.

Evaluation of Curcumin-Piperine Supplementation in COVID-19 Patients Admitted to the Intensive Care: A Double-Blind, Randomized Controlled Trial.

BACKGROUND: Curcumin is a traditional remedy for diseases associated with hyper-inflammatory responses and immune system impairment. Piperine, a bioactive compound in black pepper, has the potential to enhance curcumin bioavailability. 0This study aims to examine the effect of the curcumin-piperine co-supplementation in patients infected with SARS-CoV-2 and admitted to the intensive care unit (ICU). MATERIAL AND METHODS: In this parallel randomized, double-blind, placebo-controlled trial, 40 patients with COVID-19 admitted to ICU were randomized to receive three capsules of curcumin (500 mg)-piperine (5 mg) or placebo for 7 days. RESULTS: After 1 week of the intervention, serum aspartate aminotransferase (AST) (p = 0.02) and C-reactive protein (CRP) (p = 0.03) were significantly decreased, and hemoglobin was increased (p = 0.03) in the curcumin-piperine compared to the placebo group. However, compared with the placebo, curcumin-piperine had no significant effects on the other biochemical, hematological, and arterial blood gas and 28-day mortality rate was three patients in each group (p = 0.99). CONCLUSION: The study results showed that short-term curcumin-piperine supplementation significantly decreased CRP, AST, and increased hemoglobin in COVID-19 patients admitted to the ICU. Based on these promising findings, curcumin appears to be a complementary treatment option for COVID-19 patients, although some parameters were not affected by the intervention.

The effect of phytochemicals in prediabetic patients: A systematic review of randomized controlled trials.

This study aimed to perform a systematic review to evaluate the effect of phytochemical consumption on the cardiometabolic parameters of prediabetic patients. A comprehensive search was conducted in PubMed, Scopus and ISI Web of Science, and Google Scholar up to June 2022 to find randomized controlled trials investigating the effects of phytochemicals alone or in combination with other nutraceuticals on prediabetic patients. Twenty-three studies with 31 treatment arms comprising 2177 individuals were included in this study. Totally, in 21 arms, phytochemicals had positive effects on at least one measured cardiometabolic factor. In 13 out of 25 arms, fasting blood glucose (FBG) and in 10 out of 22 arms, hemoglobin A1c (HbA1c) significantly decreased compared with the control group. Furthermore, phytochemicals had beneficial effects on 2-h postprandial and postprandial glucose, serum insulin, insulin sensitivity, and insulin resistance as well as inflammatory factors including high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor α (TNF-α), and interleukin 6 (IL-6). Triglyceride (TG) was the abundant improved factor in the lipid profile. However, no sufficient evidence for notable positive effects of phytochemicals on blood pressure and anthropometry indices was observed. Phytochemical supplementation may have beneficial impacts on prediabetic patients by ameliorating glycemic status.

A situation analysis on postmenopausal women's self-care needs and priorities in Tehran: a population-based study.

BACKGROUND: Women need special care during and after menopause. Due to the emphasis of the World Health Organization on promoting self-care in postmenopausal women, this study aims to analyze the situation and prioritize the self-care needs of postmenopausal women in the Tehran-Iran. METHODS: This was a descriptive-analytical study on 486 postmenopausal women aged 46-85 years living in Tehran in 2021. The Subjects were recruited using a multi-stage sampling method. Data were collected using a socio-demographic and a valid and reliable questionnaire to assess postmenopausal women's self-care status with four domains including physical health, psychosocial health, reproductive-sexual health, and screening tests. The data were analyzed by SPSS-24. RESULTS: The mean age of the participants was 62.58 ± 7.75 years. The mean score of self-care was 44.63 ± 21.64% in the postmenopausal women. The lowest score and highest scores were related to psychosocial health (25.12 ± 28.21%) and periodic tests (50.62 ± 24.40%) respectively. There were significant positive correlations between self-care with women's education level (r = 0.277; p < 0.001), husband's education level (r = 0.258; p < 0.001), as well as monthly income (r = 0.153; p = 0.001). There was a negative correlation between self-care with the number of children (r = - 0.215; p < 0.001). The level of self-care was higher in employed women (p = 0.001) and also, in women whose husbands were employed (p = 0.012). Multiple linear regression test showed the level of education of the husband (B = 2.72, p = 0.038) and the family size (B = -1.54, p = 0.023) are predictors of the self-care of postmenopausal women. CONCLUSION: The findings showed more than 55% of challenges in the self-care behaviors of postmenopausal women in Tehran. The most and least challenging self-care behaviors were related to psychosocial health and performing periodic tests. The priorities were in psychosocial health and reproductive-sexual health dimensions. Self-care promotion is necessary, especially in postmenopausal women, who need special care due to various physical, psychological, and social changes.

Evaluation Of The Effectiveness of Dantrolene Sodium against Digoxin-Induced Cardiotoxicity In Adult Rats.

BACKGROUND: Digoxin poisoning commonly occurs in people treated with digoxin. It has been suggested that treatment with dantrolene may be a suitable strategy for digoxin-induced cardiotoxicity. OBJECTIVE: The aim of this study was to evaluate the protective effect of dantrolene on digoxin-induced cardiotoxicity in male rats. METHODS: This study was approved by the ethics committee of Birjand University of Medical Sciences (Ethical number: IR.BUMS.REC.1400.067). Forty-two Wistar rats weighing between 300- 350 gr were randomly allocated to 7 groups (n=6) as follows:Normal Saline (NS) group, Normal Saline + Ethanol (NS + ETOH) group), Normal Saline + dantrolene 10 mg/kg (NS + Dan 10) group, Digoxin (Dig) group), Digoxin + dantrolene 5 mg/kg (Dig + Dan 5) group),Digoxin + dantrolene 10 mg/kg (Dig + Dan 10) group), Digoxin + dantrolene 20 mg/kg (Dig + Dan 20) group), Dig was injected intravenously at 12 mL / h (0.25 mg / mL). Dan (5, 10 and 20 mg/kg) was injected intravenously at 5-8 min/mL. After 1 hour, blood samples were obtained from the animals&#039; cavernous sinus and each animal&#039;s heartremoved. The blood sample was rapidly centrifuged at 2,500 rpm for 10 minutes and the serum was separated for measurement of creatine phosphokinase (CPK), potassium (K), sodium (Na), calcium (Ca), and magnesium (Mg). The samples were stored at -20 oC. The heart samples were fixed in formalin 10% for histopathological evaluation. RESULTS: K levels slightly increased in the dig group versus the NS group. A significant increase in the K levels was observed in the Dig + Dan 20 group versus the NS group (p < 0.001). dig slightly decreased Ca levels in the treated group versus the NS group. The levels of Ca significantly increased in the Dig + Dan 10 group versus the Dig group (p < 0.05). Histological examination of the heart tissue in the dig group showed cardiomyocyte degeneration, increased edematous intramuscular space associated with hemorrhage, and congestion. Focal inflammatory cell accumulation in the heart tissue was also seen. Cardiomyocytes were clear and arranged in good order in the Dig + Dan 10 group. CONCLUSION: dantrolene (10 mg/kg) was cardioprotective in a model of digoxin-induced cardiotoxicity, secondary to cardiac remodeling and hyperkalemia. However, further research is necessary to determine dantrolene&#039;s cardioprotective and cardiotoxic doses in animal models.

Pharmaceutical toxicity is a common pattern of inpatient acute poisonings in Birjand City, East of Iran.

Information on the pattern of acute poisonings in hospitals of Birjand city, Iran, is limited. This study aimed to address this knowledge gap by examining the admissions in a major poisoning center in eastern Iran. This cross-sectional study included patients admitted to the Imam Reza Hospital in Birjand over 12 months. Medical records of the poisoned patients were reviewed, and the study variables were used for data analysis. During the study period, 534 cases of acute poisonings were evaluated. The patient's ages ranged from 12 to 84 years, with a high rate of poisonings between 15 and 35 years. The female predominance in poisoning cases was 52.1%. Most cases of poisonings occurred in spring, and the common route of exposure was oral (93.1%). The incidence of poisoning in married couples, uneducated patients, and residents of urban areas was 56.5%, 90.1%, and 74.6%, respectively. Patients with a previous medical history experienced addiction and psychiatric disorders. Intentional poisoning accounted for 23.4% of acute poisoning cases referred to the hospital in the current study. The main groups of toxicants were pharmaceutical products (48.1%), narcotics (25.8%), chemical products (10.1%), envenomation (7.1%), and alcohol (1.7%). The mean hospital stay was 2.5 ± 3.0 days, and the final treatment outcome was complete recovery, except for one patient intoxicated by warfarin and alprazolam. Our results indicate that the high toxicity cases were related to pharmaceutical product and opioids abuse, especially methadone (8.4%), alprazolam (7.9%), clonazepam (7.5%), and acetaminophen (9.9%) taken orally and more commonly happened at home. Due to the high rate of deliberate poisonings, especially among young adults and students, monitoring drug distribution and exceptional attention to mental health should be seriously considered by national health authorities to prevent suicide attempts.

Oxytocin Effect in Adult Patients with Autism: An Updated Systematic Review and Meta-Analysis of Randomized Controlled Trials.

INTRODUCTION: The efficacy of oxytocin in the treatment of autism spectrum disorder (ASD) has not been fully characterized. This systematic review and meta-analysis study evaluated randomized controlled trials (RCTs) on the treatment of intranasally administered oxytocin for autism. METHODS: The study was conducted in accordance with the PRISMA statement. Two authors searched Scopus, PubMed/ Medline, Google Scholar, and Web of Science search engines and databases from inception through December 2020. Quality assessment was carried out by with the "ROB-2, Cochrane collaboration's tool". The random-effects model was used for pooled analyses. I2 and Q tests were used to investigate study heterogeneity. The visual inspection of funnel plots along with Egger's regression asymmetry test was used to assess the potential sources of publication bias. RESULTS: Ten RCTs were selected for the systematic review. No study corroborated the efficacy of oxytocin for the treatment of anxiety and repetitive behavior. One out of 4 studies reported clinical improvement in severity, and 1 out of 6 studies indicated improvement in social function. Our metaanalyses findings suggest that oxytocin shows no significant efficacy in the treatment of anxiety (SMD: -0.168, SE= 0.112; 95% CI: -0.387, 0.050, p = 0.132), repetitive behavior (SMD: -0.078, SE= 0.155; 95% CI: -0.382, 0.225, p = 0.614), social function (SMD: -0.018, SE= 0.133; 95% CI: -0.279, 0.242, p = 0.891) and severity (SMD: -0.084, SE= 132; 95% CI: -0.343, 0.175, p = 0.524) of autism. No significant heterogeneity nor publication bias were observed between studies. CONCLUSION: Our findings failed to corroborate the efficacy of oxytocin in the treatment of ASD. Nonetheless, given the several limitations of our study, the results should be interpreted cautiously and stimulate future research on this timely topic.

Investigating different dimensions of infertile women's quality of life: a descriptive cross-sectional study.

BACKGROUND: Infertility is a major challenge in the life of women which affects their quality of life. Infertile women's quality of life is a relatively new field of research that has recently been considered by health researchers. However, there has been no standard tool for measuring different aspects of infertile women's quality of life with female factors, and general and specific tools of infertile couples have been used to assess their quality of life. This study, thus, aimed to analyze different aspects of the quality of life of infertile women. METHODS: This descriptive cross-sectional study was conducted on 320 infertile women referred to a teaching hospital affiliated with Mazandaran University of Medical Sciences and private infertility treatment centers in Sari, Iran. Demographic and fertility characteristics and the quality of life questionnaire for infertile women questionnaire (a 25-item tool was designed which measured 7 factors of psychological effects, sexual life with infertility family and social effects, infertility-related concerns, physical effects, adaptive approaches and factors preventing infertility adaptation), were recruited for data gathering. Data were analyzed using SPSS version 22. Descriptive statistics (percentage, mean, standard deviation), correlation coefficient, independent sample t-test, and multiple linear regression were used. P-values less than 0.05 were considered statistically significant. RESULTS: The total mean score of infertile women's quality of life was 65.68 ± 8.91%. Findings were indicative of infertile women's quality of life in the dimensions of adaptive approach (70.48 ± 15.02%), psychological (67.88 ± 12.06%), family and social (64.63 ± 10.76%), physical, 63.42 ± 11.36%), inhibitory factors/ factors preventing adaptation (60.98 ± 8.24%), related concerns (51.52 ± 10.21%) and sexual life (40.12 ± 14.28%). According to the final multiple linear regression model, women's education (B = 2.57, p < 0.001), spouse's education (B = 1.56, p = 0.046), economic status (B = 1.64, p < 0.001), age of women (B = -0.62, p < 0.001), age of spouse (B = -0.65, p < 0.001), duration of infertility (B = -0.36, p = 0.024) and duration of marriage (B = -0.39, p = 0.022) were the final predictors of the quality of life score in infertile women of the study. CONCLUSION: Given that infertility causes extensive changes in individuals, families, and social dimensions of infertile women, it can affect their quality of life. We can take steps to improve the health of infertile women by promoting various dimensions of their quality of life.

Evaluation of the effectiveness of the modified nutrition risk in the critically ill (mNUTRIC) score in critically ill patients affected by COVID-19 admitted to the intensive care unit (ICU).

BACKGROUND: COVID-19 is a very harmful pandemic, and its recovery process is highly influenced by nutritional status; however, an appropriate nutritional scale has not yet been proposed for these patients. Therefore, the purpose of this study was to evaluate the effectiveness of the modified Nutrition Risk in the Critically ill (mNUTRIC) score in critically ill patients affected by COVID-19 admitted to the intensive care unit (ICU). MATERIAL AND METHODS: This was a cross-sectional study performed on 204 critically ill patients affected by COVID-19 admitted to the ICU wards. Evaluated indicators include the mNUTRIC Score as well as demographic, and biochemical indicators. RESULTS: A high percentage of COVID-19 patients (67.2%) had severe disease. Hospital and ICU stay (p > 0.001) and PH (p > 0.001) values were significantly lower in non-survivors than in survivors. mNUTRIC score (p > 0.001), PCO2 (p = 0.003), and CRP levels (p = 0.021) were significantly higher in non-survivors than survivors. mNUTRIC score had a direct correlation with age (p > 0.001), AST (p = 0.000), LDH (p = 0.026), and CRP (p = 0.014) and an inverse correlation with hospital duration (p = 0.031), albumin (p = 0.003) and PH (p < 0.001). Furthermore, there was a non-significant correlation between the mNUTRIC score and mortality chance (OR = 1.085, 95%CI [0.83, 1.42], p = 0.552). While, patients with more severe COVID-19 disease (OR = 8.057, 95%CI [1.33, 48.64], p = 0.023) and higher PCO2 (OR = 1.042, 95%CI [1.01, 1.08], p = 0.023) levels had higher odds of mortality. CONCLUSIONS: Our findings revealed that COVID-19 patients with higher CRP levels and lower PH had higher mortality and poor nutritional condition. Moreover, there was a non-significant association between the mNUTRIC score and mortality chance.
