This method follows different goals. This study aims to investigate the effect on psychiatry residents of changing journal clubs from the traditional method to the evidence-based method. Method: This study was conducted using a before–after design. First- and second-year residents of psychiatry were included in the study. First, the status quo was evaluated by standardized questionnaire regarding the effect of journal club. Then, ten sessions were held to familiarize the residents with the concept of journal club. After that, evidence-based journal club sessions were held. The questionnaire was given to the residents again after the final session. Data were analyzed through descriptive statistics (frequency and percentage frequency, mean and standard deviation), and analytic statistics (paired t-test) using SPSS 22. Results: Of a total of 20 first- and second-year residents of psychiatry, the data of 18 residents were finally analyzed. Most of the subjects (17 [93.7%]) were females. The mean overall score before and after the intervention was 1.83±0.45 and 2.85±0.57, respectively, which showed a significant increase (P

Background and Objectives: Obesity is one of the major health problems in the developed and developing countries. Therefore, this study was conducted to determine the prevalence of obesity and overweight in preschool children in Rafsanjan. Materials and Methods: In this cross-sectional study, the status of obesity, overweight, normality, weight loss and severe weight loss in 1292 pre-school children was investigated in 2018. Data were analyzed using chi-square test and one-way ANOVA. Results: Of the total number of children, who were examined, 91 children (7.0%) were very thin, 248 children (19.2%) thin, 750 children (58.0%) normal, 108 children (8.4%) overweight and 95 children (7.4%) obese. The results also showed no statistically significant association between gender and the state of obesity and weight loss in the children (p=0.303). Conclusion: Considering the relatively high prevalence of obesity and overweight, it seems necessary to examine the causes and take action to prevent it. [ABSTRACT FROM AUTHOR]

Background: Opioid-induced constipation (OIC) is the most prevalent side effect of methadone maintenance therapy (MMT). Naloxone could reduce the OIC., Method: Fifty-six MMT cases (< 75 mg/day methadone, > 3 months) were entered randomly into four groups of a trial. They received placebo or naloxone tablets (0.5, 2, or 4 mg/day) once a day for 2 weeks. They continued their conventional laxative. Their constipation and opiate withdrawal (OWS) were evaluated by the Bristol Stool Form Scale (stool consistency and frequency), Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire, Constipation Scoring System (CSS), and the Subjective Opiate Withdrawal Scale (SOWS) before starting treatment and at the end of the first and second weeks., Results: The dose of 4 mg/day naloxone was excluded from the study due to severe OWS. The precipitants of groups had similar ages, methadone dose and duration, laxative use, and constipation scores at the start of the trial. However, 2 mg of naloxone could change the stool consistency (PV = 0.0052) and frequency (P = 0.0133), 0.5 mg/day dose only improved the stool consistency (P = 0.0016). The patients' CSS and PAC-SYM scores were reduced by naloxone after the 1st week of treatment. However, there was no significant difference in the mean score of SOWS at different assessment times and groups. Also, 3 and 4 cases of 0.5 and 2 mg/day groups, respectively, withdrew from the study due to OWS., Conclusion: Oral naloxone at doses of 0.5 and 2 mg/day was significantly more effective than placebo on OIC in MMT. However, the dose of 4 mg induced intolerable OWS., (© 2024. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.)

Backgrounds: Restless legs syndrome (RLS) is an unpleasant condition that affects the quality of life of patients. Its prevalence in increased in women with premenstrual syndrome (PMS). Vitamin D plays a key role in female reproduction through its impact on calcium homeostasis and neurotransmitters. We aimed to evaluate the effect of dairy products fortified with Vitamin D 3 on RLS in women with PMS., Materials and Methods: We conducted a 2.5-month, randomized, total-blinded clinical trial to evaluate the effectiveness of low-fat milk and yogurt fortified with vitamin D on RLS in women with PMS. Among 141 middle-aged women with abdominal obesity, 71 and 70 cases received fortified and non-fortified low-fat dairy products, respectively. All subjects completed a Symptoms Screening Tool (PSST) and RLS questionnaires., Results: The results showed that in the women with severe PMS (PSST > 28), serum levels of vitamin D increased significantly following vitamin D fortification. The mean restless legs score in the severe PMS subgroup (PSST > 28) was significantly lower after the intervention (p < 0.05. Serum Vitamin D levels significantly differed between intervention and control groups in all individuals (PSST < 19, PSST 19-28, and PSST > 28) (p < 0.05), but no significant differences were found between RLS scores of the intervention and control groups in the three PMS subgroups (p > 0.05)., Conclusion: Fortifying dairy products with vitamin D 3 can increase the serum levels of vitamin D and reduce the RLS severity in women with severe PMS, but not in other groups., (© 2024.

Every year millions of people are burned and many of them are transported to specialized burn centers. One of the most important challenges in the face of burn patients in urban areas is deciding about referring patients to specialized burn centers. In this study, correlation between referral distance and mortality rate is investigated. Our cross-sectional analytic study included admission data of 7248 burn patients from Imam Reza Burn Center (Mashhad, Iran) over 9 years. The outcomes of interest were mortality, length of hospital stay, and the Abbreviated Burn Severity Index (ABSI). Also, we measured the distance between the patient referral location to Mashhad. SPSS version 16 was used for data analysis. Overall, 52.7% of admitted patients were referred from hospitals in other cities. The referred group had more severe burn injury (P < .001), higher mortality rate (P < .001), and longer length of hospital stay (P < .001). The referred distance was associated with an increased risk of death (Odds ratio = 1.68, 95% CI, 1.47-1.92), but after controlling the severity of burns, only ABSI was the statistically significant predictor of mortality (Odds ration = 2.17, 95% CI, 2.05-2.28). Therefore, increasing the distance from urban areas to specialized burn center did not increase the mortality rate. After adjusting for ABSI, the mortality rate in referred patients was not related to referral distance. By observing referral points based on available guidelines, distance from a referral burn center does not affect mortality rate independently. Therefore, equipping the existing burn centers instead of building new ones and focusing on improving referral system can be a good strategy in low- and middle-income countries with limited resources., (© The Author(s) 2023.

Background: Infections with herpes simplex virus type 2 (HSV-2) and varicella-zoster virus (VZV) are associated with serious maternal and neonatal health consequences. The literature review reveals a research gap regarding the seroprevalence of HSV-2 and VZV among women of reproductive age in Mashhad, Northeast of Iran. The present study aims to evaluate the seroprevalence of these viruses among a group of women in Mashhad, Iran., Methods: Sera were collected by health center personnel using a cluster sampling method from healthy women with specific age characteristics residing in three distinct socioeconomic regions of the city. The participants, aged 20-35, were divided into three groups (20-25, 26-30, and 31-35 years). The levels of VZV and HSV-2 IgG antibodies were evaluated using commercial ELISA kits. Subsequently, the results were analyzed using SPSS software., Results: A total of 93 women were included in the study. Anti-HSV-2 IgG antibody was detected in 3 out of 93 participants (7.5%), while anti-VZV IgG antibody was found positive in 80 out of 93 individuals (83.3%). The HSV-2 positive cases were concurrently positive for the VZV antibody. There was no significant difference in the positivity of anti-HSV-2 and anti-VZV antibody positivity within age groups or socioeconomic status ( P > 0.05)., Conclusions: The high seroprevalence of VZV among nonvaccinated participants indicates a widespread presence of the virus and underscores its potentially serious impact on community health. Therefore, it is recommended that a VZV vaccination program be considered by the health system. Furthermore, the reactivation of latent HSV-2, whether symptomatic or asymptomatic, during pregnancy should not be disregarded as a life-threatening threat., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 International Journal of Preventive Medicine.)

Background: Bariatric surgery delivers substantial weight loss for obese patients with comorbidities like diabetes mellitus. We aimed to investigate the impacts of bariatric surgery on diabetic markers after 5 years of follow-up. Methods: This is a retrospective study on patients with diabetes and a history of bariatric surgery between 2016-2017. The diabetic markers before and 5 years following surgery, including a lipid profile, glucose level, and the required antidiabetic medications, were evaluated. Results: 34 consecutive patients were included, 30 (88.2%) women, with a mean age of 52.71±8.53 years. The majority (65%) of surgeries were Roux-en-Y gastric bypass (RYGB), and the remaining were one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG). The serum levels of diabetic markers reduced during follow-up ( P =0.001), except for high-density lipoprotein levels and serum total cholesterol, which increased ( P =0.011, P =0.838). Low-density lipoprotein levels reduced, but it was insignificant ( P =0.194). Surgery types had affected the changes of diabetic markers ( P >0.05). Demand for oral medication was reduced significantly, but insulin injection reduction was not significant ( P =0.006 and P =0.099, respectively). Conclusion: Our study showed favorable bariatric surgery results on patients with diabetes in long-term follow-up. However, dyslipidemia is still a concern., Competing Interests: Competing Interests The authors declare no conflict of interest related to this work., (© 2023 Middle East Journal of Digestive Diseases.)

Inflammatory processes in the brain play a role in acute mania etiopathogenesis. There is little evidence indicating the efficacy of celecoxib adjuvant therapy in treatmenting of manic episodes of bipolar disorder. Therefore, this clinical trial aimed to assess the celecoxib effect on treating acute mania. In a double-blind, placebo-controlled trial, 58 patients meeting the criteria for acute mania were enrolled. After considering eligibility, 45 patients were included in the study and randomly divided into two groups. The first group (23 patients) received sodium valproate 400 mg/day along with celecoxib 400 mg/day, and the second group (22 patients) received sodium valproate 400 mg/day and a placebo. The subjects were evaluated by the Young Mania Rating Scale (YMRS) at the beginning of the study and 9, 18, and 28 days following the initiation of the medication. Evaluation of baseline factors indicated a significant difference in age ( P  = 0.01) and psychiatric history ( P  = 0.02) between the two groups. However, other factors were similar between groups ( P  ≥ 0.05). Comparing the YMRS score between celecoxib and placebo groups revealed no significant difference on days 0, 9, 18, and 28. However, the YMRS score at the end of the study decreased by 16.05 ± 7.65 in the intervention group ( P  < 0.001) and 12.50 ± 5.98 in controls ( P  < 0.001) compared to the baseline, the trend of change was not significant between the two groups during the time of the study ( F  = 0.38; P  = 0.84). Although celecoxib adjuvant therapy indicated no considerable side effects, a longer treatment duration may be needed to detect its beneficial effects for treating acute mania in bipolar patients.

Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus known to be associated with adult T-cell lymphoma and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Previous researches and brain imaging techniques have suggested cognitive abnormalities as well as brain damage in individuals infected with this virus. Given the insufficient amount of studies on how this virus can impact the affected person's cognition, we aimed to assess and compare the cognitive abnormalities of HAM/TSP patients, asymptomatic HTLV-1 carriers, and healthy controls. This cross-sectional study was conducted on 51 patients divided into 3 groups; a group of HAM/TSP patients, a group of asymptomatic HTLV-1 carriers, and an uninfected control group. Each group contained 17 members. The cognitive state of the studied population was assessed using the Mini-Mental State Exam (MMSE), Symbol Digit Modalities Test (SDMT), Rey-Osterrieth complex figure test (ROCF), the "Verbal Fluency Test" and the "Trail Making Test" (TMT) components of the Delis-Kaplan executive function system (D-KEFS) test, the Rey Auditory Verbal Learning Test (RAVLT), and digit span memory test. Patients diagnosed with HAM/TSP received significantly lower scores on the SDMT, ROCF, TMT, RAVLT, digit span memory test, and the orientation, calculation, and recall component of the MMSE assessment (p-value < 0.001). In addition, the asymptomatic HTLV-1 carriers obtained lower scores on the SDMT, ROCF, digit span memory test, and the orientation, calculation, and recall component of the MMSE assessment compared to the control group (p-value < 0.001). Overall, the findings suggest that HAM/TSP, or an asymptomatic infection with HTLV-1 could lead to cognitive deficits in the affected individuals. This can further emphasize the importance of assessing the cognitive function and psychiatric abnormalities of those infected with this virus., (© 2023.

Human T-cell lymphotropic virus type 1 (HTLV-1) can induce a neuroinflammatory condition that leads to myelopathy. Pentraxin 3 (PTX3) is an acute-phase protein that its plasma concentration increases during inflammation. We aimed to determine whether PTX3 serum level is elevated in HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients and HTLV-1 asymptomatic carriers (ACs) and evaluate its association with proviral load and clinical features. The serum level of PTX3 was measured using an enzyme-linked immunosorbent assay in 30 HAM patients, 30 HTLV-1 ACs, and 30 healthy controls. Also, the HTLV-1 proviral load was determined via real-time PCR technique. The findings showed that PTX3 serum level was significantly higher in HAM patients than in both asymptomatic carriers and healthy controls (p values < 0.0001). No correlation between PTX3 and the proviral load was observed in HAM patients and asymptomatic carriers (r = - 0.238, p = 0.205 and r = - 0.078, p = 0.681, respectively). The findings showed that there was no significant correlation between PTX3 and motor disability grading (MDG) (r = - 0.155, p = 0.41) nor urinary disturbance score (UDS) (r = - 0.238, p = 0.20). Higher levels of PTX3 are associated with HTLV-1-associated myelopathy compared to asymptomatic carriers. This finding may support the idea that PTX3 has the potential as a diagnostic biomarker., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

We aimed to evaluate the effect of spirulina sauce on glycemic indices, lipid profile, oxidative stress markers, and anthropometric measurement in type 2 diabetic patients. Forty patients were randomly assigned to receive 20 g/day spirulina sauce (containing 2 g of spirulina) or placebo for 2 months. Anthropometric and biochemical indices were measured at the beginning and end of the intervention. Fasting blood glucose (mean difference (MD): -15.3 mg/dL, 95% confidence (CI): -44.2 to 13.60, p  = .26), HbA1c (MD: 0.13%, 95% CI: -0.83 to 0.57, p  = .75), insulin (MD: -1.46 μIU/mL, 95% CI: -4.0 to 1.09, p  = .28), and HOMA-IR (MD: -0.35, 95% CI: -2.0 to 1.32, p  = .68) did not change significantly between groups. QUICKI increased significantly (MD: 0.025, 95% CI: 0.006 to 0.045, p  = .03). Among the lipid profile, triglyceride (TG) (MD: -68.6 mg/dL, 95% CI: -107.21 to -29.98, p  < .001), total cholesterol (MD: -29.55 mg/dL, 95% CI: -55.28 to -3.81, p  = .02), and LDL (MD: -17.7 mg/dL, 95% CI: -33.24 to -2.15, p  = .01) were significantly decreased in the spirulina group compared to the control; whereas, the change in HDL was non-significant. No significant change was observed in body composition and anthropometric measurements, except waist circumference, which was reduced (MD: -2.65 cm, 95% CI: -3.91 to -1.38, p  = .001). Hunger index significantly decreased and fullness increased marginally significantly. Although malondialdehyde was significantly reduced, no change was observed in total antioxidant capacity (TAC). Spirulina sauce was not effective for glycemic control in type 2 diabetes; however, could be useful for controlling appetite and ameliorating lipid profile., Competing Interests: No conflicts of interest., (© 2023 The Authors.

Objectives: The present study was designed to conduct a comprehensive systematic review and meta-analysis to assess the efficacy of herbal medicines as add-on therapy on lung function in asthmatic patients., Methods: A comprehensive search of online databases was performed up to December 2021 to identify randomized controlled trials that used orally herbal preparations for asthma as add-on therapy. Studies were assessed for methodological quality using the Cochrane Collaboration's Risk of Bias tool. The main outcome was percent predicted value of forced expiratory volume (% predicted FEV1). Pooled weighted mean difference (WMD) estimate with corresponding 95% confidence interval (CI) was calculated using inverse-variance weights method while random effects meta-analysis was used, taking into account clinical and conceptual heterogeneity., Results: As a result, 1,525 studies were identified. 169 studies were reviewed in-depth and 23 studies met our systematic review inclusion criteria. Finally, nine randomized controlled trials were included in the meta-analysis. Findings indicated that use of herbal medicines in patients with asthma significantly improved % predicted FEV1 (WMD 3.73, 95% CI 1.76-5.70), with no evidence for significant heterogeneity (p = 0.56 [Q statistic], I 2 = 0.0%). In subgroup analysis by age, improvement in % predicted FEV1 was higher and significant in adults (WMD 5.16; 95% CI 2.68-7.63) compared to children (WMD = 1.27; 95% CI -1.98-4.51). Sensitivity analysis showed the significant effect of herbal medicine consumption on improving FEV1 was consistently (range of summary WMDs 3.27-4.59), indicating that the meta-analysis model was robust. There was no evidence of publication bias both visually and statistically., Conclusion: Findings support, the complementary use of herbal medicines resulted in significant improvement in the lung function compared to standard treatment in asthmatic patients with no considerable adverse events. This improvement is more likely to be observed amongst adults., Competing Interests: CONFLICTS OF INTEREST The authors declared there were no conflicts of interest related to the study., (© 2023 Korean Pharmacopuncture Institute.)

Background: Coronavirus disease 2019 (COVID-19) viral load determined from the cycle threshold (CT) values may be a marker of disease severity and predict disease progression. Our study aimed to investigate the relationship between SARS-CoV-19 cycle thresholds or viral load, laboratory markers, and patient prognosis., Methods: Patients who were admitted to Imam Reza Hospital at Mashhad University of Medical Sciences between March 2020 and March 2021 and had COVID-19 polymerase chain reaction (PCR)-confirmed at random were included in this cross-sectional study. Patients were randomly selected from those who tested positive on nasopharyngeal and oropharyngeal reverse transcription-PCR samples. The inclusion criteria were all patients older than 16 years with positive COVID-19 PCR results. Samples with Ct values of ≤36 were considered positive for SARS-CoV-2 RNA. Patients who did not have laboratory markers were excluded. We used SPSS Version 16 (Pearson correlation, analysis of variance, and logistic regression tests) to analyze the data. A P ≤ 0.05 was considered statistically significant., Results: In our study, serum lactate dehydrogenase and aspartate aminotransferase were found to be laboratory biomarkers inversely correlated with COVID-19 Ct values, indicating higher viral load (r = -0.14; P = 0.024 and r = -0.12; P = 0.053, respectively). Also, the platelet count is lower in patients with higher viral loads (r = 0.18; P < 0.001). However, we found no correlation between the viral load and some laboratory biomarkers such as ferritin, white blood cell and lymphocyte count, alanine transaminase, and c-reactive protein ( P > 0.05). The patient's length of hospital stay was not correlated with their viral load ( P > 0.05)., Conclusion: The COVID-19 viral load has been linked to some laboratory indicators and may be used to predict patient death. These discoveries might help in the treatment of COVID-19 disease., Competing Interests: The authors declare that they have no competing interests., (© 2023 Iran University of Medical Sciences.)

Background: Anemia is a serious public health problem which may be associated with cardiovascular diseases (CVDs) and brain damage. This survey aims to determine the prevalence of anemia and its association with demographic and biochemical factors and metabolic syndrome in a human sample derived from the MASHAD cohort study., Methods: This survey was conducted on a sub-sample of 9847 individuals aged 35 to 65 as part of the MASHAD cohort study. Demographic characteristics and biochemical and anthropometrics indices were recorded. Data were analyzed using SPSS version 20., Results: Anemia was seen in 11.5% of the population. Anemia was significantly more prevalent in younger subject ( P <0.001), females ( P <0.001) and those with elevated body mass index (BMI) ( P <0.001). Mean high-density lipoprotein (HDL) was higher in anemic participant ( P =0.032). The incidence of anemia was significantly lower in smokers ( P <0.001) and also participant with hypertension (HTN) ( P <0.001), diabetes mellitus (DM) ( P <0.001) and metabolic syndrome (MetS) ( P <0.001). Mean FBG ( P <0.001), TG ( P <0.001), total cholesterol ( P <0.001), LDL ( P <0.001) and uric acid ( P <0.001) were significantly lower in anemic subjects. Cholesterol, MetS, low-density lipoprotein (LDL), BMI, uric acid, diabetes mellitus and also TG remained significantly different after multivariate analysis between anemic and healthy participants., Conclusion: The studied population had a lower prevalence of anemia compared to the previous WHO report for Iranians. Iron deficiency is recognized as the most important cause of anemia in Iran; however, further investigations will be need to confirm this pattern. We demonstrated that anemia is adversely associated with MetS and DM., (© 2023 The Author(s).

Introduction: The findings of previous studies are inconclusive in terms of psychological abnormalities and sexual function in asymptomatic human lymphotropic virus type 1 (HTLV-1) carriers., Aim: This study aimed to evaluate the prevalence of sexual dysfunction and its relationship with psychological abnormalities in asymptomatic HTLV-1 carriers., Materials and Methods: This cross-sectional study was conducted on asymptomatic HTLV-1 patients who were referred to the Neurology Clinic of a tertiary hospital in Mashhad, Iran. Patients with spastic paraparesis, leukemia, and uveitis, and those with an expanded disability status scale (EDSS) score higher than 2 were excluded. Sexual function in male and female subjects was evaluated using the brief male sexual function inventory (BMSFI) and female sexual dysfunction index (FSFI) questionnaires, respectively. The severity of psychological symptoms was evaluated in all patients using the symptom checklist-90-revised (SCL-90-R) questionnaire., Results: A total of 117 patients (61 males and 56 females) with a mean age of 35.3 ± 6.3 years were evaluated. Overall, 50.9% of males had a high and 39.3% of females had a good sexual function. Both male and female patients with poor sexual function were older and had more children compared to those with good sexual function ( P < 0.05). There was no significant difference in the distribution pattern of SCL-90 domains between patients with high and low to moderate sexual function among male patients ( P > 0.05). Depression, hostility, interpersonal sensitivity, paranoid ideation, and psychological abnormality were significantly more prevalent in female patients with poor sexual function compared to those with good sexual function ( P < 0.05)., Conclusion: The prevalence of psychological abnormalities was high in female with sexual dysfunction and these disorders might have a negative effect on various dimensions of sexual function., Competing Interests: The authors have no conflict of interest to declare., (Copyright: © 2023 Indian Journal of Psychiatry.)

Background: Training professional medical experts is so much dependent on the efficacy of the medical curriculum. Bearing this in mind, we aimed to evaluate the attitude of the undergraduate medical students toward the Early clinical exposure (ECE) program as a facilitator transition to the clinical phase., Methods: This quasi-experimental study was conducted on undergraduate medical students at the Mashhad University of Medical Sciences, Mashhad, Iran who were transferring from the pre-clinical course to the externship course from 2021 to 2022 by census method (i.e. all eligible students were included and no sampling was performed). An eight-session ECE intervention was performed on the participants by two professors of the Internal medicine department of Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. The participants' attitude toward the program and the program quality was assessed with the valid and reliable scale developed by Mirzazadeh et al. (Cronbach's alpha = 0.72). Statistical analyses were performed by SPSS software (version.16) with a statistically significant level of less than 0.05., Results: A total of 118 undergraduate medical students were enrolled in the study. Our results revealed that this program could familiarize (n = 95,81.2%)the students with the role of basic sciences knowledge in clinical settings, and 104(88.9%) participants believed that this intervention could motivate them toward learning more. The data revealed that this program was highly interesting for international students. There was a significant differentiation between Iranian and international students in familiarity with doctoring skills in medicine(P < 0.001), familiarity with the roles and responsibilities of clinical students(P < 0.001), and utility of early clinical exposure and providing more experiences(P < 0.001). According to the students' reports, the major strengths of the program were familiarizing themselves with the clinical fields, having excellent instructors, and performing admirable training. On the other hand, the major weakness of the program was the short duration and the high population of participants in each group., Conclusions: The ECE program had a positive impact on the students' satisfaction with medical education, and it also enhanced their understanding of the role they will play as future physicians. Therefore, we recommend that this program be implemented as a part of the medical education curriculum in medical universities., (© 2023. The Author(s).)

Background: Nutrition management is an important pre-operative and post-operative challenge in liver transplantation. Preoperative malnutrition is associated with increased length of intensive care unit (ICU) stay, mortality, and length of hospital stay in liver transplant patients. This study aimed to evaluate the nutritional status of patients before and after liver transplantation and post-transplant complications., Method: This longitudinal study was conducted on liver transplant patients in Montaserieh Hospital, Mashhad and Firoozgar Hospital, Tehran from May 2021 to January 2022. Demographic characteristics, Subjective Global Assessment (SGA) standard questionnaire, anthropometric indices, laboratory analyses, and 3-day food records were collected before, one, and three months after transplantation., Results: Thirty-nine patients with a mean age of 48.4 ± 14.2 were evaluated. Prevalence of severe malnutrition was 43.6% (56.3% women and 34.8% men) before transplantation. Body mass index (BMI), body weight, lean mass, total body water, and total serum protein significantly decreased after transplantation compared to before transplantation (P < 0.001). One month after transplantation, 54% of the patients lost more than 10% of their weight. Energy intake increased significantly after transplantation (P < 0.001). A significant relationship was observed between BMI (P = 0.005) and metabolic complications and between Arm Muscle Circumference and renal complications (P = 0.003) after transplantation. A cut-off point of 4.6 was determined for the phase angle in terms of SGA three months after transplantation., Conclusion: Malnutrition, weight loss, and nutritional problems were common in liver transplantation patients. Screening for nutritional status is necessary in these patients to treat or prevent malnutrition-related complications., Competing Interests: Declaration of competing interest Authors have no conflict of interest to declare., (Copyright © 2022 European Society for Clinical Nutrition and Metabolism.

Human BK polyomavirus (BKPyV) is a latent infectious agent in the genitourinary tract associated with hemorrhagic cystitis and nephropathy. This virus can be a risk factor for various human malignancies, including prostate cancer (PCa). It may contribute to prostate cancer development, as it demonstrates oncogenic properties by encoding oncoproteins. This study assessed the prevalence of this virus in benign and malignant prostate tissues. Between 2009 and 2019, 49 formalin-fixed paraffin-embedded (FFPE) PCa and 49 benign prostatic hyperplasia (BPH) samples were gathered from the pathology department of a tertiary care university hospital. They were used as cases and controls, respectively. After deparaffinization and DNA extraction, nested PCR was applied to identify the BKPyVgp5 gene (LTAg) using inner and outer primers. The nested PCR showed a 278-bp bond corresponding to the BKPyVgp5 genome (LTAg) in 53.1% (26/49) of PCa and 14.3% (7/49) of BPH (p<0.001). The presence of BKV was significantly associated with an increased risk of PCa development (OR=6.78, 95% CI=2.55-18.02, p<0.001). The BKV LTAg gene was significantly more prevalent in PCa samples than in BPH samples. These results demonstrate the presence of the virus in prostate cancer tissues., Competing Interests: The authors declare no conflict of interest.

Psychosis is a state of mind that makes it difficult to determine what is real and what is not. Psychosis can have serious negative effects. Like many psychiatric phenomena, psychosis has a variety of causes, such as schizophrenia, bipolar disorder, and psychotic depression. Antipsychotic medications, psychotherapy, and social support are the most common treatments. Antipsychotic drugs reduce the symptoms of psychosis by changing brain chemistry. Based on the mechanism of action, antipsychotics have two groups, typical and atypical. Most people who take antipsychotics experience side effects. People taking typical antipsychotics tend to have higher rates of extrapyramidal side effects, but some atypical drugs, especially olanzapine, are associated with the risk of significant weight gain, diabetes, and metabolic syndrome, which, in turn, increases the risk of atherosclerotic cardiovascular disease and premature death. Physical exercise, diet regimen, psychoeducation, monotherapy, or switching to an alternative antipsychotic are strategies to correct metabolic aberrates in atypical antipsychotic users. In light of several successful studies on the use of medicinal plants to control metabolic syndrome, this article briefly reviews the studies on some herbal medications for the management of metabolic disorders associated with atypical antipsychotics and discusses probable mechanisms. Therefore, we searched the Cochrane, Scopus, PubMed, and Google Scholar databases for works published before July, 2022, on the effect of herbal medications on antipsychotic-related metabolic abnormalities in animals or humans. We recommend that some herbal medicines may be efficient for regulating the metabolic changes related to atypical antipsychotics due to their multipotential action, and more efforts should be made to make herbal drug treatments more effective. We hope this review will be a reference for research on developing herbal therapeutics for metabolic alterations in antipsychotic customers., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

No study, best of our knowledge, has been conducted on assessing the validity and reliability of community attitudes toward the mentally ill (CAMI) inventory in Iran. The questionnaire was translated into Persian and then returned to English. Content validity ratio (CVR), content validity index (CVI), impact score (IS) to assess content validity, Cronbach's alpha, and test-retest reliability was used to prove the internal and external reliabilities, respectively. The questionnaires were distributed to 130 people from different levels of society. Some were in contact with at least one patient with mental illness and some others had no connection. After 2 weeks, the questionnaires were resent to 50 participants to evaluate the reliability using the test-retest method. All questions had CVI (>0.79) and CVR (>0.49) except for three questions (Q 10, 24, and 30), which were excluded from the questionnaire. The questions were relevant, clear, simple, and valid. The IS was more than 1.5. The Cronbach's alpha values of four subscales including authoritarianism, benevolence, social restrictiveness, and community mental health ideology were recorded as 0.61, 0.49, 0.64, and 0.76, respectively. The CAMI scale is a valid and sustainable tool over time to assess the negative attitude toward mental illness., (Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.)

Acorn is a nutritious fruit with the reported potential of ameliorating diseases, including diabetes. This research aimed to assess the effects of acorn muffin consumption on glycemic, lipid indices, and appetite in patients with type 2 diabetes. Sixty-six subjects were dichotomized to receive either one muffin containing 10 grams of acorn flour or a placebo muffin containing white wheat flour (no bran), per day, for 8 weeks. Acorn muffin consumption improved glycated hemoglobin ( p  = .06, mean difference [MD] = -0.65), triglyceride ( p  = .06, MD = -36.38), and high-density lipoprotein ( p  = .05, MD = 1.30), albeit only marginally significantly. Among appetite parameters, hunger, desire to eat, and prospective to eat were significantly lower, and satiety and fullness were significantly higher, in the acorn muffin group. In conclusion, acorn muffins could be utilized as an adjuvant therapy to control appetite and ameliorate glycated hemoglobin in patients with type 2 diabetes. However, further investigations are required for a more comprehensive conclusion., Competing Interests: None., (© 2022 The Authors. Food Science & Nutrition published by Wiley Periodicals LLC.)

Background: Three-dimensional models are used to guide residents and physicians in accessing specific anatomical areas and types of fractures and better diagnosis of anomalies. These models are useful for illuminating complex anatomical areas, such as orbit, especially limited space with sensitive access. The aim of this study was to design a three-dimensional visualization educational modeling for ophthalmology residents' training. Methods: This study is a product-oriented application that uses radiological images of anatomy, anomalies, and orbital fractures based on actual CT scans of patients. These CT scans were carefully selected from the Picture Archiving and Communication System of Ghaem Hospital of Mashhad University of Medical Sciences. Results: To produce twelve 3D models, the CT scan files were converted to 3D printer output. Then, the models were presented to residents at a training session by an ophthalmologist. These models created all major fractures associated with the orbit area and most disorders, anomalies of this area and several normal anatomical. The features of 3D models were mentioned. The strengths and weaknesses of the educational modeling, the level of satisfaction with the use of three-dimensional models, suggestions and criticisms were assessed qualitatively by the residents. Satisfaction was reported 100% by residents. Suggestions for future 3D models were presented, and the only criticism was fear of exams and grades. Conclusion: Real-size 3D modeling help to understand the spatial and mental imagery of anatomy and orbital pathology and to touch different anatomical areas creates a clear image in the minds of residents, especially in the orbit., Competing Interests: The authors declare that they have no competing interests., (© 2022 Iran University of Medical Sciences.)

Background: Enteral feeding intolerance, energy-protein malnutrition, and muscle wasting are common conditions in the critical care setting. The primary aim of this study was to investigate the effect of synbiotic supplementation on enteral feed volume, energy and protein homeostasis, and muscle mass maintenance in critically ill adult patients., Methods: A consecutive of 42 patients admitted to the Edalatian Medical ICU, requiring enteral nutrition (EN), were prospectively randomized to receive the synbiotic capsule (containing a combination of Lactobacillus, Bifidobacterium, Streptococcus, and fructooligosaccharides) or placebo (21 patients in each group) for a maximum of 14 days. Enteral intolerance and energy homeostasis were evaluated on a daily basis. Nitrogen balance and 24-h urine creatinine excretion were recorded on days 1 and 14. Mid-arm circumference was recorded every 3 days., Results: Mean EN volume, energy, and protein intake per day were 962.5 ± 533.82 ml, 770 ± 427.05 kcal, and 38.5 ± 21.35 g (fourth day) vs. 590 ± 321.1 ml, 472 ± 256.81 kcal, and 23.6 ± 12.84 g (first day) in the synbiotic group (p < 0.05). Changes in the placebo group were not statistically significant. On day 1, nitrogen balance (NB) was - 19.84 ± 8.03 in the synbiotic vs. - 10.99 ± 9.12 in the placebo group (p = 0.003). On day 14, NB was - 14.18 ± 13.05 in the synbiotic and - 9.59 ± 7.71 in the placebo group (p = 0.41). Mid-arm circumference (MAC), 24-h urine creatinine, and creatinine-height index were almost steady in the synbiotic group, while they decreased in the placebo group., Conclusion: Overall, it can be concluded that enteral nutrition supplemented with synbiotics has no statistically significant effect on energy and protein homeostasis and muscle mass maintenance of critically ill patients on day 14, but it can increase enteral feed volume and energy and protein intake during the first 4 days of ICU admission., Trial Registration: The trial protocol has been approved in Iranian Registry of Clinical Trials on March 17, 2019.

Experimental autoimmune encephalomyelitis (EAE) is an appropriate model for the study of the immunologic and pathologic mechanisms in multiple sclerosis (MS). According to the hygiene hypothesis, helminths can improve immunoregulation and have therapeutic effects on immune-mediated diseases. In this study, we used Dicrocoelium dendriticum (Dicrocoeliidae, Platyhelminthes) eggs for the evaluation of their prophylactic and treatment effects on EAE disease. D. dendriticum eggs were extracted. Female C57BL/6 mice were immunized with the specific antigen MOG 35-55 , and then the egg extracts were utilized for prophylaxis and/or treatment. Clinical symptoms and other relevant parameters were assessed daily. The mRNA expression of transforming growth factor-β (TGF-β), interleukin-10 (IL-10), IL-6, IL-23 and IL-17 were assessed with a real-time polymerase chain reaction technique. Furthermore, secretion of TGF-β and IL-17 cytokines were determined by enzyme-linked immunosorbent assay. Data indicated that clinical symptoms in prophylaxis and treatment groups were decreased significantly in comparison with the untreated control group (p < .001). Our results showed a significant decrease in IL-17, as well as an increase in TGF-β cytokine in the treatment group compared to the EAE control group (p < .01). Furthermore, in the prophylaxis and treatment groups, the mRNA expression of disease-associated cytokines decreased and the mRNA expression of the anti-inflammatory cytokines increased. In this study, the D. dendriticum egg ameliorates the clinical symptoms of the EAE model through the modulation of related cytokines of Th17 and Treg cells. Therefore, using this parasite egg could be a new treatment for MS., (© 2022 John Wiley & Sons Ltd.)

Objectives: Asthma is a chronic disease, and the demand for herbal medicines in this field has increased in recent years. The new findings highlight the role of the gut-lung axis in the pathophysiology of asthma. Hence, this study will evaluate the safety and efficacy of Glasthma syrup, an herbal formula based on Persian medicine, in improving asthma and regulating intestinal permeability. The formula consists of five herbal ingredients that have anti-inflammatory effects on the respiratory tract, also known as gut tonics., Methods: The study will be conducted as a placebo-controlled, triple-blind, randomized trial. It will consist of a 4-week intervention followed by a 4-week follow-up period. The target sample size is 20 patients with moderate asthma aged 18 to 60 years. Eligible participants will be randomly assigned to either the experimental group or the control group in equal numbers. Patients in the experimental group will take Glasthma syrup (7.5 mL, twice a day), while patients in the control group will take a matching placebo. Both groups will receive a 4-week combination of a long-acting beta2 agonist and a leukotriene modulator as standard of care. Inhaled corticosteroids can be used as rescue medication as needed., Results: The primary outcomes are asthma symptom scale, lung function, and intestinal permeability. Secondary outcomes include quality of life, symptom recurrence rates, and blood tests. A safety assessment will also be conducted during the trial., Conclusion: In this trial, the effects of Glasthma syrup in patients with moderate asthma will be examined. The study will also assess the effects of the formulation on the gut-lung axis by simultaneously monitoring the gut permeability index, asthma symptoms, and lung function., Competing Interests: CONFLICT OF INTEREST The authors declare no conflict of interests., (© 2022 Korean Pharmacopuncture Institute.)

Introduction: In traumatic brain injury (TBI) patients, inflammatory processes and oxidative stress have been linked to the development of neurodegenerative diseases, disability, increased rate of muscle catabolism, malnutrition, hospital stay and mortality. Previous in vitro and in vivo studies have shown that trehalose can decrease inflammatory and oxidative factors. Therefore, the present study was designed to evaluate the effect of oral trehalose consumption on this marker in critically ill TBI patients at intensive care unit (ICU)., Methods and Analysis: This study is a pilot randomised, prospective and double-blind clinical trial. The study sample size is of 20 (10 patients in each group) TBI patients aged 18-65 years at ICU. Randomisation is performed by permuted block randomisation method. The allocation ratio is 1:1. An intervention group will receive 30 g of trehalose instead, as a part of the carbohydrate of daily bolus enteral feeding and the control group will receive standard isocaloric hospital bolus enteral feeding for 12 days. The inflammatory factors (C reactive protein, interleukin 6) and oxidative stress markers (glutathione, malondialdehyde, superoxide dismutase, pro-oxidant-antioxidant balance, total antioxidant capacity) will be measured at the baseline, at the 6th day, and at the end of the study (12th day). Sequential Organ Failure Assessment, Acute Physiology and Chronic Health Evaluation II, Nutrition Risk in the Critically ill scores, 28-day mortality, anthropometric assessments and the clinical and nutritional status will be measured. Each patient's nutritional needs will be calculated individually. The statistical analysis would be based on the intention to treat., Ethics and Dissemination: The vice-chancellor of the research centre of Mashhad University of Medical Sciences is sponsoring this study.

Aim: Critical ill patients experience catabolic stress, which results in a systemic inflammatory response. The inflammatory response is associated with increased complications, including infection, multi-organ dysfunction, increased length of ICU stays, and mortality. l-Carnitine supplementation may play an important role in these patients by regulating inflammatory cell function. The purpose of the present study was to investigate the effect of l-Carnitine supplementation on clinical status, inflammatory markers, and mortality rate in critically ill patients admitted to the intensive care unit (ICU)., Methods: This randomized, double-blind, placebo-controlled trial was performed on critically ill patients. Subjects were randomly assigned into placebo (n = 27) and l-Carnitine (n = 27) groups. l-Carnitine (3000 mg/day) was administered via nasogastric tube for the intervention group for 7 days, while the other group received a placebo for the same duration. Serum levels of inflammatory markers, including C-reactive protein (CRP) and interleukin-6 (IL-6) were measured. Nutritional status and the acute physiology and chronic health evaluation (APACHE) score, sequential organ failure assessment (SOFA) score, and 28-day mortality were also recorded., Results: Fifty-one critically ill patients completed the study. l-Carnitine supplementation significantly reduced the levels of CRP (mean change ± SE: -34.9 ± 6.5) and IL-6 (mean change ± SE: -10.64 ± 2.16) compared to the baseline, which is both statistically significant compared with the control group (p < 0.05). The SOFA and APACHE scores were significantly reduced in the l-Carnitine group compared with the placebo group (p = 0.02 and p < 0.001, respectively)., Conclusions: l-Carnitine supplementation showed beneficial effects on inflammatory and clinical outcomes of critically ill patients., Trial Registration Details: Trial registration: IRCT, Registered 30 May 2018, https://www.irct.ir/trial/30748., Competing Interests: Declaration of competing interest The authors declare that, they have no competing interests., (Copyright © 2022 European Society for Clinical Nutrition and Metabolism.

The present study aimed to assess the relative validity and reliability of a modified Food and Nutrition Literacy (M-FNLIT) questionnaire in primary school children in the city of Mashhad. The study was conducted in four phases. In the first step, the content and face validity of the questionnaire were evaluated by Delphi consensus as well as interviewing the students. Then, construct validity was examined using Confirmatory Factor Analysis (CFA). The internal consistency and reliability of the questionnaire were also assessed using Cronbach α and Intraclass Correlation Coefficient (ICC), respectively. Finally, a receiver operating characteristic analysis was performed to detect the cut-off scores of the M-FNLIT scale. Findings of two rounds of Delphi showed satisfactory levels of Content Validity Ratio: 0·72 and 0·92, Content Validity Index (CVI): 0·92 and 0·98, respectively. The results of CFA for domains and subscales of the M-FNLIT questionnaire including cognitive domain (understanding food and nutrition information and nutritional health knowledge) and skill domain (functional, food choice, interactive, and critical skills) indicated acceptable fit indices. M-FNLIT subscale-specific Cronbach α values ranged between 0·68 and 0·8 and ICC was 0·95 (95 % CI 0·93, 96). The final questionnaire included forty items (thirty-six Likert-type and four true-false items). FNLIT scores were categorized as low (≤ 58), medium (> 58–< 81), and high (≥ 81). The M-FNLIT questionnaire has a good level of validity and reliability to measure food and nutrition literacy in primary school children. The questionnaire can be applied in the evaluation of nutritional interventions in this age group.

Background and Aim: One of the main causes of mortality among obese patients is cardiovascular disease (CVD). Carotid intima-media thickness (CIMT) is an independent predictor for atherosclerosis and risk of CVD, and has been demonstrated to be related with obesity. This study aimed to evaluate the effect of substantial weight loss after bariatric surgery on CIMT., Methods: This prospective study was performed on patients with morbid obesity and standard indications for bariatric surgery in a tertiary referral center in Iran. The mean CIMT values were assessed using B-mode ultrasonography before and 6 months after bariatric surgery., Results: A total of 32 patients (25 females, 7 males) with a mean age of 38.18 ± 1.18 years were enrolled. Body mass index (BMI) was significantly reduced from 43.66 ± 6.44 to 29.01 ± 2.56 kg/m 2 during 6 months following surgery (p: 0.001). The mean CIMT values at 6 months after surgery were significantly lower than the baseline (0.53 ± 0.06 vs. 0.50 ± 0.08; p: 0.001). Along with a significant hypertension and metabolic syndrome remission, we observed considerable reduction in FBS (p: 0.019), cholesterol (p: 0.061), triglycerides (p: 0.001), and insulin levels (p: 0.001). Besides, liver stiffness was significantly decreased after surgery (6.15 ± 0.82 vs. 5.26 ± 0.83; p: 0.001). There was no statistically significant correlation between changes in quantitative variables and changes in CIMT., Conclusion: Bariatric surgery results in significant reduction in CIMT, metabolic syndrome factors, and liver stiffness in patients with morbid obesity., (© 2022.

Background:  Gutmicrobiota dysbiosis, endotoxemia, and systemic inflammation are major factors contributing to disease pathophysiology in patients with critical illness. The present study aimed to assess the effects of synbiotic supplementation on serum endotoxin and inflammationof adult patients with critical illness., Methods:  This double-anonymized, randomized controlled trial was conducted at the intensive care unit (ICU) of Imam Reza Hospital in Mashhad, Iran. In the intervention group, 20 patients received synbiotic capsules (containing a combination of Lactobacillus, Bifidobacterium, Streptococcus, and fructooligosaccharides) twice per day for a maximum of 14 days. In the control group, 18 patients received placebo capsules. The serum levels of endotoxin and C-reactive protein and the neutrophil to lymphocyte ratio (NLR) were measured before and after the intervention. In addition, clinical outcomes and Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment scores were recorded., Results:  Basic characteristics were similar in the intervention and control groups. The NLR and serum endotoxin levels (median [IQR]) significantly declined in the synbiotic group (7.83 [4.58-12.57] to 6.01 [4.25-9.38]; P = .04; and 11.98 [10.64-12.65] to 10.58 [9.41-12.34]; P = .03, respectively). However, no significant changes were observed in the mentioned parameters in the placebo group. The clinical outcomes were also similar in the study groups, such as the length of hospital/ICU stay and hospital/28-day mortality rate., Conclusion:  Although synbiotic supplementation (500 mg twice daily for 14 days) could reduce serum endotoxin and inflammatory markers, it had no effects on the clinical outcomes of the patients., (© 2021 American Society for Parenteral and Enteral Nutrition.)

During chronic HTLV-1 infections oxidative stress occurs and contributes in viral pathogenesis. Glutaredoxin (Grx) system is one of the most effective antioxidant components. The system maintains the cellular redox and scavenges reactive oxygen species through the function of glutathione reductase (GR) enzyme, NADPH and reduced glutathione (GSH). This study was performed to investigate potential changes in GR gene expression and activity as well as GSH level, and their association with the viral load in HTLV-1 infection. Forty HTLV-1 seropositive patients divided into two groups: asymptomatic carriers (N = 20) and HAM/TSP (N = 20) with the same number of age and sex-matched healthy controls were recruited in this study. GR cellular gene expression and viral load in PBMCs were determined using Real-time PCR Technique. Enzyme activity and GSH level in sera were measured by commercial kits based on manufacturer's provided protocols. GR gene expression and GR enzyme activity, as well as GSH level, were significantly lower in HTLV-1 patients. A negative correlation between viral load and GR gene expression/enzyme activity was observed in HAM/TSP group. Similarly, a negative relationship between viral load and GSH levels was observed in both carrier and HAM/TSP groups. We also found that in profound complicated condition of HTLV-1 infection, HAM/TSP, Grx system components activity was significantly decreased compared to the controls. Such observation was not the case in clinically healthy HTLV-1 carriers. These findings may shed a light on the conditions contributing in pathogenesis of the complications and exacerbation of the disease in the HAM/TSP cases., Supplementary Information: The online version contains supplementary material available at 10.1007/s13337-022-00758-y., Competing Interests: Conflict of interestAuthors declare no conflict of interest., (© The Author(s), under exclusive licence to Indian Virological Society 2022.)

Background: Obesity and arteriosclerosis are both independently associated with cardiovascular disease risk. Obesity also may increase arterial stiffness., Aims: This study aimed to investigate the association between anthropometric indices and non-invasive arterial stiffness parameters, using data from a large population-based cohort of seemingly healthy women and men., Methods: A total of 5023 eligible participants were included in the study. The pulse wave velocity (PWV), central blood pressures, and bio-impedance measures were obtained at the time of enrollment. Multiple regression analysis was performed to assess the relationship between anthropometric indices with arterial stiffness parameters., Results: The mean age of participants was 45.3 ± 8.8 years, 2368 (47.1%) were males and 2655 (52.8%) were females. The prevalence of participant with underweight, normal weight, overweight, and obesity were 0.73%, 33.2%, 48.7%, and 17.2% respectively. Systolic and diastolic blood pressure, fatty liver, and hypertension were significantly higher in overweight/obesity participants. The overweight/obesity participants had significantly higher PWV than the normal-weight group (471.5 ± 42.6/496.7 ± 47.5 cm/s vs. 448.1 ± 41.4 cm/s, p  < 0.001)., Conclusion: The prevalence of diabetes, hypertension, fatty liver disease, chronic lung disease, and also kidney stones were significantly higher in overweight and individuals with obesity. Body mass index, body fat mass, waist-hip ratio abdominal circumference, neck circumference, visceral fat area, total body water, 50-kHz whole body phase angle are positively correlated with PWV. Augmentation index had no significant correlation with body mass index, arm, hip, and abdominal circumferences., Competing Interests: The authors declare no conflict of interest., (© 2021 The Authors.

Objectives: Evaluation of the incidence of infectious diseases after natural disasters can help develop healthcare policies. This study provides a global review of the most prevalent infectious diseases observed after earthquakes., Study Design: A systematic review and meta-analysis were performed., Methods: A systematic review was performed on electronic databases, including PubMed, Scopus and Web of Science, up to March 2020 (with no time limitations). Studies addressing earthquakes and infectious diseases were collected based on specified inclusion and exclusion criteria. Subsequently, the quality of the studies was assessed by the Newcastle-Ottawa scale (NOS). Data analyses were carried out on six subgroups under five different disease categories using comprehensive meta-analysis software., Results: In total, 24 studies qualified for the systematic review and 18 were included in the meta-analysis. The incidences of gastrointestinal infections, dermal infections, respiratory infections, central nervous system infections and other infectious diseases were as follows: odds ratio (OR) 163.4 (95% confidence interval [CI]: 31.0-858.1), OR 84.5 (95% CI: 27.1-262.8), OR 9.9 (95% CI: 3.5-27.7), OR 0.5 (95% CI: 0.2-1.1) and OR 4.4 (95% CI: 1.9-9.9) cases per 100,000 people, respectively. The association between the incidences of infectious diseases before and after earthquakes was significant, namely, 1.561 (95% CI: 1.244-1.957) with a P-value <0.001., Conclusions: The results show an increase in the prevalence of infectious diseases after earthquakes. Governments should take essential measures to be better prepared for such unpredictable catastrophes., (Copyright © 2021 The Royal Society for Public Health. Published by Elsevier Ltd.

Background and Aims: The aim of the present study was to investigate the effects of gut microbiota modulation through synbiotic supplementation on lipid and glucose homeostasis in tube-fed critically-ill adult patients., Methods: This study is placebo-controlled, parallel, single-center, double-blind clinical trial. 42 patients were randomly distributed in placebo and synbiotic groups to receive intervention for a maximum of 14 days. Serum levels of fasting glucose, total cholesterol, and triglycerides, insulin, and free fatty acids were obtained from blood sampling at baseline and the end of the study. Also, insulin resistance was determined by homeostasis model assessment of insulin resistance (HOMA-IR)., Result: Fasting glucose level (Day0 = 87.84 ± 15.51, Day14 = 83.76 ± 8.71 mg/dl, P = 0.51), fasting insulin level (Day0 = 9.46 ± 7.31, Day14 = 7.97 ± 5.19 mIU/L, P = 1.00), and HOMA index (Day0 = 1.89 ± 1.48, Day14 = 1.72 ± 1.17, P = 0.75) during the study were decreasing in both groups, but the decreases were not significant. Serum levels of total cholesterol, triglyceride, and free fatty acidsat the beginning of the study were 114.18 ± 43.43 mg/dl, 146.59 ± 53.99 mg/dl, 0.83 ± 0.57 mmol/L, and at the end of the study were 129.10 ± 39.05 mg/dl, 127.40 ± 91.88 mg/dl, 0.88 ± 0.77 mmol/L, respectively. None of these changes were significant either (P = 0.99, P = 0.38, P = 0.90, respectively)., Conclusions: According to our findings, synbiotics supplementation in critically ill patients has no significant effect on lipid and glucose profile., Competing Interests: Declaration of competing interest Authors declare no conflict of interest., (Copyright © 2021.

Inflammation plays an important role in the outcome of patients with cystic fibrosis (CF). It may develop due to cystic fibrosis transmembrane conductance regulator protein dysfunction, pancreatic insufficiency, or prolonged pulmonary infection. Fecal calprotectin (FC) has been used as a noninvasive method to detect inflammation. Therefore, the aim of the current meta-analysis was to investigate the relationship between FC and phenotype severity in patients with CF. In this study, searches were conducted in PubMed, Science Direct, Scopus, and Embase databases up to August 2021 using terms such as "cystic fibrosis," "intestine," "calprotectin," and "inflammation." Only articles published in English and human studies were selected. The primary outcome was the level of FC in patients with CF. The secondary outcome was the relationship between FC and clinical severity. Statistical analysis was performed using Comprehensive Meta-Analysis software. Of the initial 303 references, only six articles met the inclusion criteria. The mean (95% confidence interval [CI]) level of FC was 256.5 mg/dL (114.1-398.9). FC levels were significantly associated with pancreatic insufficiency (mean, 243.02; 95% CI, 74.3 to 411.6; p =0.005; I 2 =0), pulmonary function (r=-0.39; 95% CI, -0.58 to -0.15; p =0.002; I 2 =60%), body mass index (r=-0.514; 95% CI, 0.26 to 0.69; p <0.001; I 2 =0%), and Pseudomonas colonization (mean, 174.77; 95% CI, 12.5 to 337.02; p =0.035; I 2 =71%). While FC is a reliable noninvasive marker for detecting gastrointestinal inflammation, it is also correlated with the severity of the disease in patients with CF., Competing Interests: Conflict of Interest: The authors have no financial conflicts of interest., (Copyright © 2022 by The Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition.)

Background: The current study aimed to evaluate growth and neurodevelopmental status in patients with retinopathy of prematurity (ROP) treated with intravitreal bevacizumab (IVB)., Methods: This historical cohort study was conducted on neonates with ROP who were treated with IVB and age and birth weight-matched controls who did not need IVB. Apgar score less than five, history of blood transfusion and history of infectious diseases were among exclusion criteria. Indirect ophthalmoscopic examinations were performed till complete retinal vascularization. Growth and neurodevelopmental status were evaluated by Age and Stages Questionnaire (ASQ) at the ages of 6, 12, and 18 months. Developmental milestones were assessed in five areas (gross motor, fine motor, personal-social status, problem-solving, and relationship) and overall issues., Results: A total of 34 cases and 36 controls were included in the present study. Birth weight and corrected gestational age were not statistically different between the groups. In a follow-up period of 18 months, bevacizumab was effective as a primary treatment in the treatment of severe cases of ROP. There was no significant difference between the two groups regarding the five areas and overall issues in follow-up intervals (P > 0.05)., Conclusions: The obtained results did not show any growth and neurodevelopmental differences between treatment-naïve infants and those receiving IVB for the treatment of ROP., (© 2021.

Decreased food intake is an effective mechanism for gastric bypass surgery (GBS) for successful weight loss. This cross-sectional study aimed to assess dietary intake, micro-and macro-nutrients in the patients undergoing GBS and determine the possible associations with weight changes. We assessed anthropometric indices and food intake at 24 month-post gastric bypass surgery. Dietary data was evaluated using three-day food records. After the 24 months of surgery, among 35 patients (mean age: 43.5 ± 11.2 years; 82.85% females), with the mean body mass index (BMI) of 30.5 ± 4.5 kg/m 2 , 17 cases were < 50% of their excess weight. The average daily calorie intake was 1,733 ± 630 kcal, with 14.88% of calories from protein. Consumption amounts of protein (0.82 ± 0.27 g/kg of the current weight), as well as fiber, and some micro-nutrients (vitamin B9, E, K, B5, and D3) were lower than recommended amounts. Patients were classified into three groups based on their success in weight loss after surgery. Calorie intake was not significantly different between groups, but successful groups consumed considerably more protein and less carbohydrate than the unsuccessful group (p < 0.05). Based on our findings, the patients undergoing GBS had inadequate macro- and micro-nutrient intake after 24 months. However, protein intake can affect patients' success in achieving better weight loss. Long-term cohort and clinical studies need to be conducted to comprehend this process further., Competing Interests: Conflict of Interest: The authors declare that they have no competing interests., (Copyright © 2021.

Background: Due to the COVID-19 outbreak, protective measures including alcohol-based hand rub, received unexampled popularity in Iran. Alcohol hand rub is effective, inexpensive and simple to use, but it is a flammable liquid, which might cause burn injuries. In this study, we investigated burn injuries due to alcohol hand sanitizers during the COVID-19 disease outbreak in Iran. Methods: This cross-sectional study was performed on burn patients referred to Motahari Burns and Reconstruction Center from February 20th, 2020 (official announcement of the epidemic of COVID-19 in Iran) up to April 19th, 2020. All outpatients and hospitalized burn injuries caused by alcohol during the abovementioned period were included. Results: There were 76 burn injuries due to the use of alcohol hand sanitizer. Sixty patients were treated outpatient, and 16 were hospitalized. The mean ± SD age of patients was 33.2±17.9 years and most were males (57 individuals, 75%). Also, the mean ± SD of TBSA was 6.1±6.5%. In hospitalized ones, the mean ± SD hospital stay was 11.7±8.6 days. The most burnt area was the head (39.5%) followed by the right upper limb (35.5%) and the left upper limb (23.7%). Patients were actively engaged in burn injury in 61.8% of cases, while they were passively burnt in 34.2% of cases and in 3.9% the mechanism was unknown. Burn injuries mostly happened in the yard (22.4%) followed by the rooftop (21.1%) and outdoors (18.4%). Conclusion: Appropriate general education, especially through mass media, can reduce burns caused by alcohol-based sanitation during the COVID-19 outbreak. Most of these burn injuries involved face and hands, which are cosmetically and functionally important., (© 2021 Iran University of Medical Sciences.)
