Background: This systematic review aims to comprehensively assess the diagnostic accuracy of cognitive screening tools validated for older adults in Iran, providing evidence-based recommendations for clinicians and researchers., Methods: A comprehensive search in March 2023 across Web of Science, PubMed, Scopus, ScienceDirect, SID, IranMedex, and IranDoc, enhanced by hand-searching references and Google Scholar, identified cross-sectional studies on cognitive screening in Iranian seniors. We assessed diagnostic accuracy, cognitive domains, and test strengths and weaknesses. A bivariate random-effects meta-analysis provided summary estimates and 95% confidence intervals, illustrated in forest plots., Results: Our review, derived from an initial screening of 38 articles, focused on 17 studies involving 14 cognitive screening tools and participant counts from 60 to 350, mostly from specialized clinics. The MMSE was the only tool examined in at least three studies, prompting a meta-analysis revealing its sensitivity at 0.89 and specificity at 0.77 for dementia detection, albeit amidst significant heterogeneity (I^2 > 80%). ACE-III demonstrated the highest diagnostic accuracy for MCI and dementia, while MoCA's performance was deemed adequate for MCI and excellent for dementia. High bias risk in studies limits interpretation., Conclusion: This review identifies key cognitive tools for dementia and MCI in Iranian older adults, tailored to educational levels for use in primary and specialized care. It emphasizes the need for further validation to enhance diagnostic precision across diverse settings, within a concise framework prioritizing brevity and accuracy for clinical applicability., (© 2024.

Background: Pompe disease, classified as glycogen storage disease type II, arises from a deficiency in the acid alpha-glucosidase (GAA) enzyme, leading to glycogen accumulation in multiple tissues. The unique correlation between genotype and enzyme activity is a key feature. This case highlights an infantile-onset form, emphasizing genetic counseling and prenatal testing importance., Case Presentation: An 18-week-old infant with respiratory distress, cyanosis, and fever was admitted. Born healthy, her sibling died from Pompe disease. She presented with cardiomegaly, hypotonia, and absent reflexes. Diagnosis was confirmed by significantly reduced GAA activity. Despite treatment initiation, the patient succumbed to cardiac arrest., Conclusions: The case underscores genetic counseling's role, offering insights into prenatal testing advancements, antenatal diagnosis through echocardiography, and the significance of early intervention, particularly in infantile-onset Pompe disease., Synopsis: Genetic risk assessment and prenatal testing are crucial for families with a history of Pompe disease to improve early diagnosis and management outcomes., (© 2024.

Background: The mental health of medical residents, challenged by their intensive training, is of utmost concern. In light of reported suicides among Iranian medical residents in 2021, this study investigates the factors behind suicidal ideation among medical residents during the COVID-19 pandemic in Tehran., Methods: This study conducted a cross-sectional online survey among medical residents in various specialties in Tehran, Iran, amidst the COVID-19 pandemic. Suicidal ideation was assessed using the Beck Scale for Suicidal Ideation (BSSI), while depression, anxiety, and stress were measured using the DASS-21. It also collected demographic and clinical data from the participants. The data were analyzed using descriptive statistics, the Chi-square test, and multiple linear regression to examine the prevalence and determinants of suicidal ideation among medical residents., Results: The study enrolled 353 medical residents and found that 34.3% of them had suicidal ideation, with 10.2% indicating a high risk. The study also found high levels of depression, anxiety, and stress among the participants. The variables that significantly predicted suicidal ideation were depression, history of alcohol/substance use, personal history of suicide attempts, history of self-mutilation, family history of suicide attempts, number of shifts in a month, death of close persons because of COVID-19, and income. Depression was the strongest predictor of suicidal ideation., Conclusion: These findings underscore the urgent need for effective interventions and support systems to address the mental health needs of medical residents in Iran. The strategies should prioritize destigmatizing mental health, promoting access to mental health services, fostering a supportive training environment, and enhancing income opportunities., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Saeed et al.

Fahr's disease is a rare neurodegenerative disorder with brain calcifications and neuropsychiatric symptoms. It can have variable phenotypic expression and intermittent symptomatology, making diagnosis challenging. In this report, we describe a young female patient presenting with symptoms of psychosis and confusion, which could be indicative of a delirium superimposed on the cerebral vulnerability associated with Fahr's disease. Notably, about two years prior, she experienced multiple episodes of tonic-clonic seizures that spontaneously resolved without pharmacological intervention. She had no previous psychiatric history. Following comprehensive investigations, other organic causes were ruled out, and Fahr's disease was diagnosed based on bilateral symmetrical brain calcifications seen on a head CT scan. Her treatment regimen encompassed antipsychotics and anticonvulsants. This case highlights the importance of considering Fahr's disease as a differential diagnosis in patients with new-onset neuropsychiatric symptoms. The case also explores the atypical early onset and intermittent nature of symptoms in the absence of a positive family history, highlighting the complexity of Fahr's disease. A multidisciplinary approach and regular follow-up are crucial for optimizing patient care and monitoring disease progression. Further research is needed to enhance our understanding of Fahr's disease and develop standardized treatment strategies for this rare condition.

Background: Limited studies have examined psychometric properties of dementia screening tools in university-educated older adults. We aimed to examine this population's diagnostic accuracy of the Iranian version of Mini-Addenbrooke's Cognitive Examination (M-ACE)., Materials & Methods: Eighty-seven participants with over 60 years with university education were divided into three groups: Major neurocognitive disorder, mild neurocognitive disorder, and healthy control. The Iranian version of M-ACE, the Mini-Mental State Examination (MMSE), the Geriatric Depression Scale (GDS), the Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale and Diagnostic and Statistical Manual of Mental Disorders 5th edition-Text Revision (DSM-5) were used., Results: A high internal reliability of questionnaire was confirmed by Cronbach's alpha coefficient. One-way ANOVA and post hoc analysis confirmed a significant difference between study groups. The scores of M-ACE were found to have a high positive correlation with MMSE, IADL, ADL, and a moderate correlation with GDS. The optimal cutoff score of M-ACE to screen for mild and major neurocognitive disorders were 27.5 and 20.5, respectively., Conclusion: The M-ACE was a concise and reliable tool used to identify neurocognitive disorders in highly educated older adults, but they should be evaluated at a higher traditional cut score in earlier stages.

Background: Obesity is now well-recognized as an independent risk factor for cognitive decline. Although extensive research has been conducted on cognitive outcomes following bariatric surgery in young adults, very little is known about the impact of advanced age on the cognitive benefits of weight-loss procedures., Objectives: This study aimed to assess cognitive function in older Iranian patients before and after bariatric surgery., Setting: University Hospital METHODS: In this prospective longitudinal study, 24 older adults were examined before and 4 months after bariatric surgery using the Digit Span Test (DGS), the computerized version of the Wisconsin Card Sorting Test-64 (WCST-64), and the paper-and-pencil versions of the Trail Making Test (TMT), parts A and B, spanning the 4 cognitive domains of attention, working memory, processing speed, and executive functioning. The bariatric surgery group was simultaneously compared to a waiting list control group., Results: At 4 months of follow-up, comparisons between the groups revealed that the surgical group performed significantly better than the control group on the forward DGS, WCST, and TMT parts A and B. In contrast, there was no significant difference between groups on the backward DGS. Further within-group comparisons demonstrated significant improvements from baseline in forward DGS, WCST, and TMT components A and B. Nevertheless, the same variables did not alter significantly over time in the control group., Conclusions: The study suggests measurable cognitive benefits following bariatric surgery in older adults., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery.

Background and Aims: Alzheimer's disease (AD) is the main cause of dementia and over the 55 million people live with dementia worldwide. We aimed to establish the first database called the Iranian Alzheimer's Disease Registry to create a powerful source for future research in the country. In this report, the design and early results of the Iranian Alzheimer's Disease Registry will be described., Methods: We performed this multicenter investigation and patients' data including age, sex, educational level, disease status, Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS) from 2018 to 2021 were collected, registered, and analyzed by GraphPad Prism software., Results: Totally 200 AD patients were registered in our database. 107 (54%) were women and age of 147 (74%) were over 65. The mean age for men and women was 76.20 ± 8.29 and 76.40 ± 8.83 years, respectively. 132 (66%) were married and 64 (32%) were illiterate. Also, 94 (47%) were in the moderate stage of disease, and 150 (75%) lived at home together with their families. The most frequent neurological comorbidity was psychosis ( n  = 72, 36%), while hypertension was the most common non-neurological comorbidity ( n  = 104, 52%). The GDS score of women in the mild stage (5.23 ± 2.9 vs. 6.9 ± 2.6, p  = 0.005) and moderate stage (5.36 ± 2.4 vs. 8.21 ± 2.06, p  = <0.001) of the disease was significantly greater than men. In univariate analysis, MMSC score was remarkably associated with stroke ( β  = -2.25, p  = 0.03), psychosis ( β  = -2.18, p  = 0.009), diabetes ( β  = 3.6, p = <0.001), and hypercholesteremia ( β  = 1.67, p  = 0.05). Also, the MMSE score showed a notable relationship with stroke ( β  = -2.13, p  = 0.05) and diabetes ( β  = 3.26, p  = <0.001) in multivariate analysis., Conclusion: Iranian Alzheimer's Disease Registry can provide epidemiological and clinical data to use for purposes such as enhancing the current AD management in clinical centers, filling the gaps in preventative care, and establishing effective monitoring and cure for the disease., Competing Interests: The authors declare no conflict of interest., (© 2022 The Authors.

Background: For screening and distinguishing between mild neurocognitive disorder (mNCD) and normal cognitive age-related changes in primary care centers, a simple and practical tool is necessary. Therefore, this study aims to determine the validity and reliability of the Farsi version of the Ascertain Dementia 8-item (AD8-F) informant interview in patients with mNCD., Methods: This is a study of the psychometric properties of the Farsi AD8. The participants include sixty informant-patient dyads with mNCD and sixty controls with normal cognition. The AD8 was compared to the mini-mental state examination (MMSE) and the Mini-Cog. As a gold standard, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for mNCD was used. The reliability was measured using internal consistency and test-retest. Validity was assessed by evaluating the content, concurrent, and construct validity. Data were analyzed via Cronbach's α, Pearson correlation, independent t-test, and analysis of variance (ANOVA) and area under the curve (AUC) by statistical package for the social sciences (SPSS) v.23., Results: Cronbach's α was 0.71. Test-retest reproducibility was 0.8. The AD8 had inverse correlations with the Mini-Cog (r = - 0.70, P < 0.01) and MMSE (r = - 0.56, P < 0.01). The area under the curve was 0.88. The optimal cutoff score was > 2. Sensitivity and specificity were 80 and 83%, respectively. The positive predictive value was 83%. The negative predictive value was 81%., Conclusion: Our results suggest that this tool can be used as a screening tool to detect a mild neurocognitive disorder in primary care centers., (© 2022.

Background: Medications currently recommended for the treatment of Obsessive-Compulsive Disorder (OCD) usually relieve the severity of symptoms by as much as 20-30%, and satisfactory treatment is obtained in 40-60% of patients with OCD. Nevertheless, the remaining symptoms continue to impair the patients' function. Therefore, it is necessary to investigate possible strategies to improve the mitigation of symptoms. In this study, the main objective was to examine and investigate the effectiveness of granisetron, which is a serotonin 5-hydroxytryptamine receptor type 3 (5-HT 3 ) antagonist, as an adjunct therapy to selective serotonin reuptake inhibitors, for the purpose of ameliorating OCD symptoms., Methods: fifty-eight patients diagnosed with OCD, based on Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, who had a Yale-Brown obsessive-compulsive scale (Y-BOCS) score of more than 21 were recruited in a double-blinded, parallel-group, placebo-controlled, clinical trial of 10 weeks to receive either granisetron (1 mg twice daily) and sertraline (100 mg daily initially followed by 200 mg daily after week 4) or placebo and sertraline. The primary outcome was OCD symptoms measured by the Y-BOCS., Results: Y-BOCS total score significantly dropped in both groups (28.9 to 17.7 for granisetron plus sertraline and 27.5 to 19.3 for placebo plus sertraline group with a slightly greater drop for granisetron plus sertraline group), while the granisetron plus sertraline group experienced a significantly greater reduction in obsession scores (Greenhouse-Geisser F(2.32,97.57) = 4.52,p-value = 0.01). Moreover, in comparison with the placebo plus sertraline group, the proportion of the patients showing complete response was considerably higher among the granisetron plus sertraline group (P-value < 0.01). No major adverse effects were observed in any of the groups., Conclusion: The results suggest that granisetron augmentation of sertraline may increase the rate of response in patients with moderate to severe non-refractory OCD. Further studies are suggested in this regard., (© 2022. The Author(s).)

Caregiving for dependent older adults with dementia has become an important public health issue. However, not much is known about the caregiver experience for caregivers of patients with dementia in Iran. This study was designed to examine the relationship between variables pertaining to primary caregivers and patients and the level of perceived caregiver burden. The participants of this cross-sectional study were 60 caregiver and care-recipient pairs presented to Rasoul-e Akram hospital and Brain and Cognition Clinic, in Tehran, Iran. A sociodemographic questionnaire, the Zarit Caregiver Burden Interview (ZBI), the General health questionnaire-28 (GHQ-28), the NEO Five-Factor Inventory (NEO-FFI), the Spiritual Well-Being Scale (SWBS), the Neuropsychiatric Inventory (NPI), and the Mini-Mental State Examination (MMSE) were used. Descriptive statistics, correlation coefficients, T -test, and multiple linear regression analyses were used in this study. Years of caregiving, hours of caregiving/week, total and subscale GHQ-28 scores, existential well-being subscale score on SWBS, and total NPI score were found to be significantly associated with the level of caregiving burden ( p  < 0.05). In addition, among the caregivers' personality traits, neuroticism and agreeableness predicted caregiver burden. Other sociodemographic factors and MMSE scores were not found to be significantly related to caregiver burden. A better understanding of the indicators of caregiver burden can help physicians, policy makers, and mental health managers to tailor the most appropriate preventative and remedial interventions for family caregivers.

Background: Sildenafil citrate is a commonly used medication for the management of erectile dysfunction. Previous studies have described some neuropsychiatric side effects of this medication. So far, however, there has been little discussion about sildenafil-induced psychosis., Case Presentation: We here present the case of a 32-year-old Iranian male, without a known psychiatric history, who developed psychotic symptoms following initiation of sildenafil. We also postulate a mechanism by which this may occur., Conclusions: This report highlights the importance of watchful observation for the occurrence of this rare but serious side effect. Further studies are needed to clarify the precise mechanism that causes sildenafil-induced psychosis., (© 2022. The Author(s).)

Background: Accurate diagnosis and management of patients with rapidly progressive dementia may be challenging during the COVID-19 pandemic, which has negatively influenced the diagnostic performances, medical resource allocation and routine care for all non-COVID-19 diseases. Case presentation: We herein present a case of a 57-year-old male with rapidly progressive cognitive decline, headache, diplopia, myalgia, unsteady gait, aggression, depression, insomnia, hallucinations and delusions of persecution. COVID-19-associated encephalitis was briefly considered as a differential diagnosis. However, this hypothesis was rejected upon further investigation. A final diagnosis of sporadic Creutzfeldt-Jakob disease was made. Conclusion: A timely and accurate diagnosis of Creutzfeldt-Jakob disease gives patients and their families the chance to receive a good standard of healthcare and avoid extensive evaluations for other conditions.

Background: Late-onset Alzheimer's disease (LOAD) is associated with many environmental and genetic factors. The effect of systemic inflammation on the pathogenesis of neurodegenerative diseases such as AD has been strongly suggested. T helper cells (Th) are one of the important components of the immune system and can easily infiltrate the brain in pathological conditions. The development of each Th-subset depends on the production of unique cytokines and their main regulator., Objective: This study aimed to compare the mRNA levels of Th-related genes derived from peripheral blood mononuclear cells of LOAD patients with control. Also, the identification of the most important Th1/Th2 genes and downstream pathways that may be involved in the pathogenesis of AD was followed by computational approaches., Methods: This study involved 30 patients with LOAD and 30 non-demented controls. The relative expression of T-cell cytokines (IFN-γ, TNF-α, IL-4, and IL-5) and transcription factors (T-bet and GATA-3) were assessed using Real-time PCR. Additionally, protein-protein interaction (PPI) was investigated by gene network construction., Results: A significant decrease at T-bet, IFN-γ, TNF-α, and GATA-3 mRNA levels was detected in the LOAD group, compared to the controls. However, there was no significant difference in IL-4 or IL-5 mRNA levels. Network analysis revealed a list of the highly connected protein (hubs) related to mitogen-activated protein kinase (MAPK) signaling and Th17 cell differentiation pathways., Conclusion: The findings point to a molecular dysregulation in Th-related genes, which can promising in the early diagnosis or targeted interventions of AD. Furthermore, the PPI analysis showed that upstream off-target stimulation may involve MAPK cascade activation and Th17 axis induction.

Background: Amongst the contributing factors of depression, vitamin D deficiency has increasingly drawn attention in recent years. This paper seeks to examine the association between serum vitamin D level and depression in patients with obesity., Methods: In this comparative observational study, serum 25-hydroxyvitamin D [25(OH)D] levels were compared between obese individuals with depression (n = 174) and those without depression considering the effect of potential confounders. Participants were selected from males and females aged 18 to 60 years old visiting the outpatient obesity clinic of Rasoul-e Akram hospital, Tehran, Iran. The diagnosis of depressive disorder was made based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. Additional clinical and laboratory data were collected from hospital electronic records. Mann-Whitney U test (nonparametric), Student's t-test (parametric), and Chi-squared test were used to analyze the differences between the two groups. To examine age and gender differences in the relationship between vitamin D deficiency and depression, stratified analyses were conducted by age and gender groups., Results: The mean 25(OH) D levels were significantly different between depressed and non-depressed groups (20 ± 15 vs. 27 ± 13, P <  0.001). Vitamin D insufficiency/deficiency was detected in 78 and 67% of the depressed and non-depressed groups, respectively, which was significantly different (P = 0.03). The associations between depression and the serum 25(OH) D levels were observed regardless of gender and age. The overall average vitamin D levels were not significantly different between total males and females (22 ± 13 vs. 23 ± 14, P = 0.49). The average level of vitamin D was higher in the older age group (40-60 years) compared to younger participants (18-39 years) (26 ± 15 vs. 21 ± 13, P = 0.004)., Conclusion: The present study provides additional evidence for the hypothesis that low vitamin D serum concentration is associated with depression in obese adults, and highlights the need for further research to determine whether this association is causal., (© 2021.

Background: Obsessive-compulsive disorder (OCD) is among the most disabling neuropsychiatric conditions characterized by the presence of repetitive intrusive thoughts, impulses, or images (obsessions) and/or ritualized mental or physical acts (compulsions). Serotonergic medications, particularly Selective Serotonin Reuptake Inhibitors (SSRIs), are the first-line treatments for patients with OCD. Recently, dysregulation of glutamatergic system has been proposed to be involved in the etiology of OCD. We designed this systematic review and meta-analysis to evaluate clinical efficacy of glutamatergic medications in patients with OCD, according to the guidelines of Cochrane collaboration., Method: We searched Medline, Scopus, and Cochrane library without applying any language filter. Two of the authors independently reviewed search results for irrelevant and duplicate studies and extracted data and assessed methodological quality of the studies. We transformed data into a common rubric and calculated a weighted treatment effect across studies using Review Manager., Results: We found 476 references in 3 databases, and after exclusion of irrelevant and duplicate studies, 17 studies with total number of 759 patients with OCD were included. In the present review we found evidence for several drugs such as memantine, N-acetylcysteine (NAC), Minocycline, L-carnosine and riluzole. Glutamaterigic drug plus SSRIs were superior to SSRI+ Placebo with regard to Y-BOCS scale [standardized mean difference (SMD = - 3.81 95% CI = - 4.4, - 3.23)., Conclusion: Augmentation of glutamatergic medications with SSRIs are beneficial in obsessive-compulsive patients, no harmful significant differences in any safety outcome were found between the groups., (© 2021.

Background: Sestrin2 and beclin1 are two newly found proteins that have essential roles in autophagy. This study attempted to evaluate the plasma concentrations of sestrin2 and beclin1 in women with polycystic ovary syndrome (PCOS) and healthy controls and to explore the clinical value of these proteins as novel biomarkers for PCOS., Methods: In this case-control study, plasma levels of sestrin2 and beclin1, fasting blood sugar (FBS), lipid profile, insulin, and androgens were evaluated in 63 women (31 patients and 32 controls). Sestrin2 and beclin1 levels were determined using enzyme-linked immunosorbent assay (ELISA). Descriptive statistics, correlation coefficients, logistic regression, and ROC curve analyses were used in this study., Results: Plasma sestrin2 levels of the subjects with PCOS (40.74 [24.39-257.70]) were significantly lower than those of healthy subjects (255.78 [25.46-528.66]; p-value = 0.040). ROC curve analysis showed that a cutoff value of 420.5 ng/L had an appropriate sensitivity (83.87%) and specificity (46.88%) for discriminating individuals with and without PCOS, with the area under the curve (95% CI) of 0.648 (0.518 to 0.764), p = 0.036. There were no statistically significant differences between the two groups concerning plasma levels of beclin1, biochemical parameters, blood pressure, and anthropometric features., Conclusion: Our findings highlight the dysregulation of sestrin2 as a marker of autophagy in PCOS and its potential usefulness as a novel biomarker for PCOS. Further research is needed to better understand the role of this protein in the pathophysiology of PCOS and its value as a diagnostic tool for the evaluation of PCOS patients., (© 2021 The Authors.

Background: Attention deficit hyperactivity disorder (ADHD) is among the most common neurodevelopmental disorders in children and adolescents. There is a controversy over the true prevalence of ADHD in Iran, the knowledge of which is crucial for allocating health care resources and identifying research priorities. This is an updated systematic review of the prevalence of ADHD in Iranian children and adolescents. Methods: For this systematic review, PubMed/Medline, Web of Science, Scopus, PsycINFO, IranPsych, IranMedex, Irandoc, Google Scholar, and grey literature were reached for publications between January 1990 and December 2018 that reported prevalence estimates of ADHD in Iran. Parallel independent assessments were conducted. The Quality Assessment Checklist for Prevalence Studies was used to assess the overall quality of studies. Results: A total of 34 original studies covering 33 621 Iranian children, adolescents, and adults were included. The included studies were mostly conducted on the population of preschool, elementary, middle, and high school-aged children as well as adolescents. Also, 6 studies addressed university students. Prevalence estimates of ADHD reported varied substantially across the studies and offered a range of heterogeneous data. Conclusion: Overall, making exact comparisons among studies was not easy because the assessment method and the type of sampling could impact prevalence estimates. These factors need to be considered when comparing data from different studies., (© 2021 Iran University of Medical Sciences.)

Background: Promoting drug-related knowledge and improving relevant attitudes among students are of crucial importance toward the prevention of drug misuse. Objective: This study aimed to assess the validity and reliability of the "drug-related knowledge and attitude questionnaire" among Iranian medical students. Methods: The participants of this cross-sectional study were students of Iran University of Medical Sciences. The "drug-related knowledge and attitude questionnaire" and a socio-demographic questionnaire were used to gather the data. Content validity was assessed by a panel of 11 experts, and face validity was evaluated by 10 participating students. Item-total correlation and Cronbach's alpha coefficients were used as internal consistency estimates. Results: The face and content validity of the questionnaire were satisfactory. The overall content validity index was .82. Cronbach's alpha was .679, indicating an acceptable degree of internal consistency and homogeneity between the items. Overall, most of the students had adequate knowledge about the harmful effects of addictive substances (48.11 ± 3.26). Conclusions: The "drug-related knowledge and attitude questionnaire" has favorable validity and reliability to assess the knowledge and attitude of Iranian students toward drug misuse and may be used in clinical and epidemiological studies. Besides, our findings can provide a suitable starting point for the implementation of effective psychoeducational interventions aimed at the improvement of the students' knowledge and attitudes toward drug misuse.

What Is Known and Objective: Major depressive disorder (MDD) is a complex disease and one of the leading contributors to disease burden throughout the world. In the current study, we explored the efficacy and tolerability of vortioxetine versus sertraline on symptoms of depression in elderly patients with MDD., Methods: Sixty patients diagnosed with MDD (based on DSM-5) and Hamilton Depression Rating Scale (HAM-D) score ≥ 19 were entered into a randomized double-blind study and were randomized to receive either vortioxetine (15 mg daily) or sertraline (75 mg daily) for six weeks. Patients were assessed using the HAM-D scale at baseline and weeks 3 and 6. Changes in HAM-D score, response rates, remission rate and time to response or remission were also compared between the two study groups., Results and Discussion: Fifty patients completed the trial after six weeks. General linear model repeated measures demonstrated no difference in trend of the two treatment groups (P = .897). There was no significantly different improvement in the HDRS scores from baseline to weeks 3 and 6, as well. Differences in response rate, remission rate, time to response and time to remission periods were not statistically significant. Finally, there was not any significantly difference between the two study groups in the frequency of adverse events., What Is New and Conclusion: This study showed no significant differences in the efficacy and safety of vortioxetine in comparison with sertraline in order for it to be used safely for treatment of major depressive disorder in elderly patients., (© 2020 John Wiley & Sons Ltd.)

Background: Dementia constitutes a public health hazard in developing countries. The aim of this study was to evaluate the prevalence of dementia and its associated factors in older hospitalized patients., Methods: The participants of this cross-sectional study consisted of older patients admitted to medical wards in Rasoul-e Akram hospital in Tehran, Iran. Mini-Mental State Examination, Mini-Cog test, Geriatric Depression Scale, Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, and socioeconomic questionnaires were used., Results: A total of 205 elderly inpatients were included. The mean age was 71.33 ± 7.35 years; 63.4% of the participants had normal cognitive function, while 36.6% had some degree of cognitive impairment. There was a statistically significant relationship between gender, age, number of children, and occupation and the prevalence of dementia., Conclusion: Appropriate cognitive screening of older patients upon admission to hospitals could help identify potential adverse events and enhance the quality of care for patients with comorbid dementia.
