Effect of Adding Intravenous Somatostatin to Rectal Indomethacin on Post-Endoscopic Retrograde Cholangiopancreatography (ERCP) Pancreatitis in High-risk Patients: A Double-blind Randomized Placebo-controlled Clinical Trial.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) has an important role in the treatment of pancreaticobiliary disorders. GOALS: Considering the high prevalence and importance of postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) and the controversial findings, we aimed to determine the effect of adding intravenous somatostatin to rectal indomethacin on the incidence of PEP in high-risk patients. STUDY: In this prospective study, 530 patients underwent ERCP during March 2018 and February 2019. Patients were randomized into 2 groups. The intervention group received a bolus injection of 250 µg somatostatin followed by an infusion of 500 µg of somatostatin for 2 hours. In both groups, 100 mg of pre-ERCP suppository indomethacin was administrated. All patients were screened for PEP symptoms and signs for 24 hours after ERCP (Iranian Registry of Clinical Trials code: IRCT20080921001264N11). RESULTS: A total of 376 patients were finally analyzed. PEP was the most common adverse event with 50 (13.2%) episodes, including 21 (5.5%) mild, 23 (6.1%) moderate, and 6 (1.2%) severe. The rate of PEP was 15.2% in the control group and 11.4% in the intervention group ( P =0.666). The incidence of post-ERCP hyperamylasemia was 21.7% in the control group and 18.2% in the intervention group ( P =0.395). No death occurred. CONCLUSIONS: In this study administration of somatostatin plus indomethacin could safely reduce the rate of post-ERCP hyperamylasemia and PEP in the intervention group compared with the control group, but the differences were not significant. Further studies with larger sample sizes are required.

Serum and salivary tissue transglutaminase IGA (tTG-IGA) level in celiac patients.

BACKGROUND: Celiac disease (CD) is a genetically determined autoimmune disease triggered by gluten consumption. Patients with these conditions have intraepithelial lymphocytosis, crypt hyperplasia, and severe intestinal atrophy. Gluten elimination is the only way to reduce this chronic inflammation. The diagnosis of CD is usually made by analyzing anti-tTG, anti-DGP, or EMA serological tests, and it is confirmed by biopsy of the duodenum. In people with CD, xerostomia or dry mouth is a common complication. This condition causes the salivary glands to malfunction and, in turn, may result in oral plaque and periodontal disease. By comparing salivary and serum levels of tissue transglutaminase IgA (tTG-IgA), this study aims to suggest a non-invasive method for diagnosis of CD. Furthermore, the present study evaluates the severity of xerostomia symptoms in people with CD. METHODS: In this case-control study, participants were patients referred to the internal ward of Sayyad Shirazi hospital. The control group was selected from healthy people who attended Gorgan Dental College. In this study, an analysis of serum was performed following consent from patients. This was followed by a salivary test, and the results of both tests were compared. The Xerostomia Inventory questionnaire was also used to determine the severity of xerostomia. As part of this study, examination of factors such as total protein concentration of saliva, albumin concentration, amylase level, pH, sodium, calcium, potassium, phosphorus, and interleukin (6, 18, and 21) were conducted. RESULTS: A total of 78 people were studied (aged 15 to 68), 26 were male (33.3%) and 52 were female (66.7%). In comparisons of the serum and saliva of people with and without CD, the level of amylase was higher in the latter group. The average levels of IL-6، IL-18 ،IL-21, and salivary and serum tTG were higher in people with CD. Additionally, CD patients were more likely to develop xerostomia. CONCLUSION: Study findings showed that CD can reduce certain salivary enzymes and elements, as well as increase inflammatory cytokines, salivary, and serum tTG. The management of dry mouth should also be recommended for celiac disease patients in order to prevent its complications.

The relation between serum levels of interleukin 10 and interferon-gamma with oral candidiasis in type 2 diabetes mellitus patients.

BACKGROUND: Type 2 Diabetes mellitus (T2DM) is one of the most common endocrine diseases that weakens the immune system. Candida albicans, is part of the natural oral flora and increases in cases of compromised immune systems. The exact cause of the increased prevalence of candidiasis in patients with T2DM is still unclear. The study aimed to correlate serum interleukin 10 (IL-10) and interferon-gamma cytokines (IFN-γ) with oral candidiasis in T2DM. METHODS: In this case-control study, 81 patients with T2DM and 41 non-diabetic individuals aged 30 to 70 years participated. Demographic information, a Blood sample (for blood glucose and cytokine tests), and an oral cotton swab sample from each individual were obtained. The samples were then incubated in a Sabroud dextrose agar medium. Colony growth was calculated and the type of yeast species in individuals with oral candidiasis was identified by culture in CHROMagar Candida medium. IL-10 and IFN-γ were measured by ELISA kit and the data were analyzed using SPSS-18. RESULTS: An overall of 122 participants comprised 73.77% females and 26.22% males. An increase in interleukin-10 by 40% and a decrease in IFN-γ by 6% can increase oral candidiasis prevalence among diabetic patients. Candida albicans was the most prevalent Candida species (spp.) in the diabetic and non-diabetic groups. The presence of oral candidiasis was not associated with HbA1c or FBS levels in both groups. CONCLUSION: In the diabetic population, an increase in IL-10 or a decrease in IFN-γ may be associated with an increased risk of oral candidiasis.

Association Between Helicobacter pylori Colonization and Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: Various observational studies have examined a potential relationship between Helicobacter pylori colonization and inflammatory bowel diseases (IBDs); however, results are inconclusive. This systematic review evaluates articles reporting an association between human H. pylori colonization and IBD. METHODS: A systematic search of studies was conducted to evaluate a possible relationship between H. pylori colonization and IBD. Seven databases and different types of gray literature were searched. After screening for relevant articles, selection and data extraction were done. After that, the data were analyzed, and pooled odds ratios (ORs) were calculated, using meta-analysis. Heterogeneity, sensitivity, and subgroups analyses were conducted. Funnel plots followed by Begg and Egger tests were done to assess the publication bias. RESULTS: Among 58 studies, including 13,549 patients with IBD and 506,554 controls, the prevalence of H. pylori colonization was 22.74% and 36.30%, respectively. A significant negative association was observed between H. pylori colonization and IBD (pooled OR: 0.45, 95% confidence interval 0.39-0.53, P≤0.001). The random-effect model showed significant statistical heterogeneity in the included studies (I2=79%). No publication bias was observed. Among subgroups, ORs were notably different when the data were stratified by the age difference between patient and control group, and by study regions and/or continent. Finally, the meta-regression analysis showed significant results, in terms of the age difference and region variables. CONCLUSIONS: In this meta-analysis, all statistical data support the theory that H. pylori has a protective role in IBD. However, more primary studies using proper methodology are needed to confirm this association.

Mycobacterium tuberculosis typing using Allele-specific oligonucleotide multiplex PCR (ASO-PCR) method.

Mycobacterium tuberculosis (M. tuberculosis) genotyping provides valuable information related to the origin and the evolution of the isolates. This study aimed to evaluate the applicability of single-nucleotide polymorphisms (SNPs) technique for lineages identification of M. tuberculosis and compare it with mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) method. The lineages of 162 clinically isolates were evaluated using six pair primers by Multiplex-PCR based on SNPs. Among 162 isolates, 70 (43.2%) isolates were lineage 4, following that 62 (38.3%) and 22 (13.6%) isolates were lineage 3 and 2, respectively. The method could not type 8 (4.9%) isolates. Moreover, we could identify 71 out of 79 unknown isolates resulted from the MIRU-VNTR method. The results showed that the SNP typing method has the potential to determine the lineages of M. tuberculosis as a rapid laboratory screening test.

The expansion of CD14+ CD163+ subpopulation of monocytes and myeloid cells-associated cytokine imbalance; candidate diagnostic biomarkers for celiac disease (CD).

Celiac disease (CD) is a chronic autoimmune disorder of small intestine against dietary gluten, among genetically predisposed individuals. Monocytes are versatile innate immune cells involved in the regulation of inflammation, and strongly involved in the intestinal immunity. However, the role of monocytes and their subtypes in CD is not well demonstrated. METHODS: Here, we assessed the polarization of CD14+ monocytes by evaluating the M1 (CD16) and M2 (CD163) markers by flowcytometry, their soluble forms (sCD16 and sCD163), and the serum levels of IL-10, IL-12, TGF-ß, and TNF-α cytokines using ELISA method, among 30 CD patients and 30 sex- and age-matched healthy subjects (HS). We also analyzed the diagnostic values of all variables with significant differences. RESULTS: CD14+CD163+ monocytes were more frequent in CD patients than HS, while CD14+CD16+ monocytes were higher in HS. IL-10and TNF-α increased, and TGF-ß expression was decreased among CD patients. The sCD16 serum levels were elevated in patients, while sCD163 was higher but not significant among CD patients. CD163+/CD16+ and IL-10/IL-12 ratios were higher in CD patients, and TGFß/TNFα ratio was higher in HS group. IL-10, CD14+CD163+, TNF-α, and IL-10/IL-12 ratios with the AUC over 0.7 were introduced as fair diagnostic markers. Our findings revealed that the M2 (CD14+CD163+) monocytes were more frequent among CD patients, and the cytokine balance was disturbed. CONCLUSION: According to the significant functional diversities of monocyte subtypes between CD patients and HS group, these immunologic markers could be introduced as specific diagnostic biomarkers for CD.

Incidence, risk factors and clinical characteristics of extra-pulmonary tuberculosis patients: a ten-year study in the North of Iran.

OBJECTIVE: To determine the incidence of extra-pulmonary tuberculosis (EPTB) and examine the risk factors and the clinical features of the disease over a ten-year period. METHODS: Retrospective study of records of patients who were followed and registered in the TB registry programme in the health district of Gorgan, Iran from January 1, 2008, through December 31, 2017. RESULTS: Among 2280 TB records, 609 (26.71%) were EPTB. They were mostly female patients (53.7%) and residents in rural areas (56.5%) with a mean age of 40.55 years [±16]. The average age of female patients (37.55 years [±16.99]) was lower than of male patients (44.07 years [±20.59]). The median of the incidence rate was 7.5 per 100 000 inhabitants for EPTB; biopsy and pathology were the best methods for the detection of EPTB. The most frequent forms of EPTB were lymphatic TB (193/609 = 31.7%) and pleural TB (158/609 = 25.9%). In most cases (245/609 = 40.2%), one to three months elapsed between occurrence of symptoms and final confirmation of EPTB. The outcome of EPTB was weaker than of pulmonary TB (PTB). CONCLUSION: Our most important finding was the increasing incidence of EPTB, which shows the importance of attention to this disease. Lymph node and pleural tissue were the most commonly infected tissues. Skeletal TB presents a challenge in the diagnosis and treatment of EPTB.

OBJECTIF: Déterminer l'incidence de la tuberculose extra-pulmonaire (EPTB) et examiner les facteurs de risque et les caractéristiques cliniques de la maladie sur une période de dix ans. MÉTHODES: Etude rétrospective des dossiers des patients qui ont été suivis et enregistrés dans le programme d'enregistrement de la TB dans le district de santé de Gorgan, en Iran, du 1er janvier 2008 au 31 décembre 2017. RÉSULTATS: Parmi 2.280 enregistrements de TB, 609 (26,71%) étaient des EPTB. Il s'agissait principalement de femmes (53,7%) et de résidents des zones rurales (56,5%) avec un âge moyen de 40,55 ans [± 16]. L'âge moyen des patients de sexe féminin (37,55 ans [± 16,99]) était inférieur à celui des hommes (44,07 ans [± 20,59]). La médiane du taux d'incidence était de 7,5 pour 100.000 habitants pour l'EPTB; la biopsie et la pathologie étaient les meilleures méthodes pour la détection de l'EPTB. Les formes les plus fréquentes d'EPTB étaient la TB lymphatique (193/609 = 31,7%) et la TB pleurale (158/609 = 25,9%). Dans la plupart des cas (245/609 = 40,2%), un à trois mois s'étaient écoulés entre l'apparition des symptômes et la confirmation finale de l'EPTB. Le résultat de l'EPTB était plus faible que celui de la TB pulmonaire (PTB). CONCLUSION: Notre découverte la plus importante a été l'incidence croissante d'EPTB, ce qui montre l'importance de l'attention portée à cette maladie. Les ganglions lymphatiques et les tissus pleuraux étaient les tissus les plus fréquemment infectés. La TB osseuse présente un défi dans le diagnostic et le traitement de l'EPTB.

The inhibitory effects of carvacrol, nystatin, and their combination on oral candidiasis isolates.

BACKGROUND: Candida, a common oral microbiota, can cause opportunistic fungal infections. With rising Candida infections and limited effective antifungals, new treatments are needed. This study investigates carvacrol essential oil's effect on oral candidiasis, alone and with nystatin, compared to nystatin alone. MATERIALS AND METHODS: In this study, oral samples were collected from dental clinic patients, especially denture users. The presence of Candida was confirmed and cultured from these samples. Candidiasis was detected by observing Candida colonies. Drug sensitivity was tested on 100 positive samples. The minimum concentration of inhibition and lethality of each isolate was evaluated using nystatin and carvacrol. The results were compared using two-way analysis of variance. Finally, the minimum inhibitory concentration (MIC) of nystatin and carvacrol was calculated individually and in combination. RESULTS: The present study found that Candida albicans and non-albicans species were equally prevalent. Carvacrol showed significant biological activity against all Candida species, with an average MTT of 50.01%. The average MIC value of carvacrol was 24.96 µg/ml, indicating its potential to inhibit Candida growth. The mean Minimum Fungicidal Concentration (MFC) value of carvacrol was 23.48 µg/ml, suggesting its effectiveness in killing the fungi. CONCLUSION: The study's findings reveal that the MIC of carvacrol was significantly lower than that of nystatin and the combination of nystatin and carvacrol. This suggests that carvacrol holds potential as an effective herbal remedy for candidiasis.

Risk factors and treatment outcome of smear positive pulmonary tuberculosis patients: A five-year study in the North of Iran.

Background: It is essential to constantly review the risk factors and treatment outcomes of tuberculosis (TB). This study evaluated some important risk factors of TB over five years. Methods: Between 2013 and 2018, all available information and possible risk factors related to TB patients were analyzed from the TB registry program of the health district of Gorgan, Iran. Results: Among 349 TB patients, 194 (55.59%) were males and 167 (47.85%) had at least a comorbidity. The death rate was higher in the age group more than 65 years (p < 0.001), the low-educated group (P = 0.012), and patients with underlying diseases, especially diabetes (p < 0.001). In total, univariate and multivariate statistical analyzes showed that having comorbidity (OR = 4.34; 95% CI 1.49 - 13.49), as well as, being jobless (OR = 3.07; 95% CI 1.19 - 8.59) were the main factors influencing the adverse events. Conclusion: According to the study, aging, underlying diseases, and cultural poverty include a higher share of the main risk factors for active TB and/or treatment outcomes. By considering these risk factors and training the medical staff continually, we can reduce the time of TB diagnosis, and prevent it from spreading.

Effectiveness of an Informal Home Care Support Intervention Program to Reduce Loneliness and Improve Quality of Life among Lonely Community-Dwelling Older Adults: A Feasibility Study.

Background: Establishing cost-effective informal care services for lonely older adults living at home in developing countries can be an innovative approach for improving their well-being. This study investigated the effectiveness of an informal home care support intervention program (HoSIP) reducing the loneliness and improving quality of life of lonely community-dwelling older adults. Methods: This quasi-experimental pre-post study employed a non-randomized control group design with a 12-week intervention period and three follow-up points at the end of the HoSIP. Questionnaires were used to measure feelings of loneliness (20-item UCLA Loneliness Scale), quality of life (Control, Autonomy, Self-Realization and Pleasure Scale), general health (12-item General Health Questionnaire), social network (six-item Lubben Social Network Scale), social support (12-item Multidimensional Scale of Perceived Social Support), and self-care ability (17-item Self-care Ability Scale for the Elderly). Repeated-measures analysis of variance was used to gauge the effect of the intervention program over time and in comparison to the control group. Data analyses were performed using the IBM SPSS Statistics software (IBM Corp., USA). Results: We found a significant relationship between the outcome variables, including feelings of loneliness (P<0.001) and quality of life (P<0.001), at different stages of measurement. Despite the positive feasibility results, the implementation of the HoSIP faced challenges due to a lack of facilities (e.g., place restriction for holding educational classes, educational facilities like computers, video projector, and whiteboard at daycare center) and the absence of supporting organizations. Conclusion: Utilizing the existing capabilities of older adults to provide online and face-to-face care services can be a cost-effective way to improve their quality of life and reduce loneliness. The process of facilitating such informal care services for lonely older adults should be managed by either governmental or non-governmental organizations to reduce the rate of social isolation among this vulnerable population.

Differential privacy preserved federated learning for prognostic modeling in COVID-19 patients using large multi-institutional chest CT dataset.

BACKGROUND: Notwithstanding the encouraging results of previous studies reporting on the efficiency of deep learning (DL) in COVID-19 prognostication, clinical adoption of the developed methodology still needs to be improved. To overcome this limitation, we set out to predict the prognosis of a large multi-institutional cohort of patients with COVID-19 using a DL-based model. PURPOSE: This study aimed to evaluate the performance of deep privacy-preserving federated learning (DPFL) in predicting COVID-19 outcomes using chest CT images. METHODS: After applying inclusion and exclusion criteria, 3055 patients from 19 centers, including 1599 alive and 1456 deceased, were enrolled in this study. Data from all centers were split (randomly with stratification respective to each center and class) into a training/validation set (70%/10%) and a hold-out test set (20%). For the DL model, feature extraction was performed on 2D slices, and averaging was performed at the final layer to construct a 3D model for each scan. The DensNet model was used for feature extraction. The model was developed using centralized and FL approaches. For FL, we employed DPFL approaches. Membership inference attack was also evaluated in the FL strategy. For model evaluation, different metrics were reported in the hold-out test sets. In addition, models trained in two scenarios, centralized and FL, were compared using the DeLong test for statistical differences. RESULTS: The centralized model achieved an accuracy of 0.76, while the DPFL model had an accuracy of 0.75. Both the centralized and DPFL models achieved a specificity of 0.77. The centralized model achieved a sensitivity of 0.74, while the DPFL model had a sensitivity of 0.73. A mean AUC of 0.82 and 0.81 with 95% confidence intervals of (95% CI: 0.79-0.85) and (95% CI: 0.77-0.84) were achieved by the centralized model and the DPFL model, respectively. The DeLong test did not prove statistically significant differences between the two models (p-value = 0.98). The AUC values for the inference attacks fluctuate between 0.49 and 0.51, with an average of 0.50 ± 0.003 and 95% CI for the mean AUC of 0.500 to 0.501. CONCLUSION: The performance of the proposed model was comparable to centralized models while operating on large and heterogeneous multi-institutional datasets. In addition, the model was resistant to inference attacks, ensuring the privacy of shared data during the training process.

Paranormal believers show reduced resting EEG beta band oscillations and inhibitory control than skeptics.

Paranormal believers' thinking is frequently biased by intuitive beliefs. Lack of inhibition of these tempting beliefs is considered a key element in paranormal believers' thinking. However, the brain activity related to inhibitory control in paranormal believers is poorly understood. We examined EEG activities at resting state in alpha, beta, and gamma bands with inhibitory control in paranormal believers and skeptics. The present study shows that paranormal belief is related to the reduced power of the alpha, beta, and gamma frequency bands, and reduced inhibitory control. This study may contribute to understanding the differences between believers and skeptics in brain activity related to inhibitory control in paranormal believers.

The Role of Cognitive Control in Paranormal Beliefs: A Study Based on Performance in Go/No-go Task.

Introduction: Cognitive control plays a role in human behavior and mental processes and affects paranormal beliefs. This study aims to investigate the role of cognitive control in paranormal beliefs using the go/no-go task. Methods: A total of 92 people were selected based on low, middle, and high scores in the revised paranormal belief scale (R-PBS) and assigned to 3 groups. The groups included 30 severe paranormal believers (13 females with a mean age of 25.3 years), 31 mild paranormal believers (14 females with a mean age of 26.4 years), and 31 skeptics (16 females with a mean age of 25.8 years). All participants were tested on the go/no-go task. A multivariate analysis of variance was conducted with the given groups (severe paranormal believers, mild paranormal believers, and skeptics) as the independent variable and the go/no-go subscales scores as dependent variables. Results: The findings showed a significant difference between the mean scores in errors of go (F(2, 89)=7.20, P=0.01), errors of no-go (F(2, 89)=11.81, P=0.01), and reaction time (F(2, 89)=21.46, P=0.01) between the groups. Conclusion: The severe and mild paranormal believers had lower accuracy and slower reaction times than the skeptics group. Therefore, severe paranormal believers and mild paranormal believers had a weakness in all go/no-go subscale scores. This finding suggests that paranormal beliefs may be related to poor cognitive control. Highlights: Believers show weak cognitive control.Skeptics perform better in accuracy and reaction time.Paranormal beliefs linked to poor cognitive control. Plain Language Summary: This study explores why some people strongly believe in paranormal phenomena while others don't. This study investigated the connection between cognitive control (our ability to manage thoughts and behavior) and paranormal beliefs. They found that individuals with stronger paranormal beliefs had poorer cognitive control, as they made more errors and had slower reaction times compared to skeptics. However, it's important to note that this study doesn't prove causation; it only highlights a potential link that needs more research. Understanding this connection is important because it helps us grasp why some people are more prone to believing in paranormal events. It also opens up avenues for studying how cognitive control affects human behavior and thinking. In conclusion, this study provides valuable insights into the relationship between cognitive control and paranormal beliefs, contributing to our understanding of human behavior and belief systems. More research can further deepen our knowledge of why people hold different beliefs and how cognitive processes influence those beliefs.

Conspiracy beliefs are associated with a reduction in frontal beta power and biases in categorizing ambiguous stimuli.

Prior beliefs, such as conspiracy beliefs, significantly influence our perception of the natural world. However, the brain activity associated with perceptual decision-making in conspiracy beliefs is not well understood. To shed light on this topic, we conducted a study examining the EEG activity of believers, and skeptics during resting state with perceptual decision-making task. Our study shows that conspiracy beliefs are related to the reduced power of beta frequency band. Furthermore, skeptics tended to misclassify ambiguous face stimuli as houses more frequently than believers. These results help to explain the differences in brain activity between believers and skeptics, especially in how conspiracy beliefs impact the categorization of ambiguous stimuli.

Association between high-sensitive cardiac troponin level and coronary artery disease: A systematic review and meta-analysis.

Background and objectives: Previous studies suggest a link between high-sensitive cardiac troponin (hs-cTn) levels and coronary artery disease (CAD). However, the nature of this relationship is disputed. To address this, we conducted a study to gather and assess evidence on the association between hs-cTn and CAD prediction. Data sources: Studies were systematically searched and collected from four databases and different types of gray literature to cover all available evidence. After the screening, the selected articles' quality and risk of bias assessment were evaluated. Synthesis method: Meta-analysis calculated std. mean difference on the extracted data. Furthermore, heterogeneity, sensitivity, subgroups, and publication bias analyses were assessed. Results: Twenty-two studies were included in this systematic review, with a total of 844 cases and 2101 control people. The results of the meta-analysis on nine studies showed a significant and positive association between hs-cTn levels and CAD (pooled std. mean difference = 0.44; 95% confidence interval = 0.14-0.73; p < 0.003), with no publication bias (p = 0.9170). Among subgroups, std. mean differences were notably different only when the data were stratified by region or risk of bias; however, subgroup analysis could not determine the source of heterogeneity. Conclusions: Available prospective studies indicate a strong association of hs-cTn with the risk of CAD and significant improvements in CAD prediction. Further investigations in both molecular and clinical fields with proper methodology and more detailed information are needed to discover more evidence and underlying mechanisms to clear the interactive aspects of hs-cTn level in CAD patients.

Resting-State Electroencephalogram (EEG) Coherence Over Frontal Regions in Paranormal Beliefs.

Introduction: Paranormal beliefs are defined as the belief in extrasensory perception, precognition, witchcraft, and telekinesis, magical thinking, psychokinesis, superstitions. Previous studies corroborate that executive brain functions underpin paranormal beliefs. To test this hypotheses, neurophysiological studies of brain activity are required. Methods: A sample of 20 students (10 girls, Mean±SD age: 22.50±4.07 years) were included in the current study. The absolute power of resting-state electroencephalogram (EEG) was analyzed in intra-hemispheric and inter-hemispheric coherence with eyes open. The paranormal beliefs were determined based on the total score of the revised paranormal belief scale (RPBS). Results: The results of this study demonstrated a significant negative relationship between paranormal beliefs and resting-state EEG in alpha band activity in the frontal lobe (left hemisphere), EEG coherence of alpha and ß1, ß2, and gamma band activities in the frontal lobe (right hemisphere) and coherence of alpha and ß1, ß2 and gamma band activities between frontal regions (two hemispheres). In addition, the results showed that coherence of α, α1, ß, and ß2 band activities between the frontal lobe (right hemispheres) and the EEG coherence of Δ, α1, and beta band activities in the frontal lobe (two hemispheres) predict paranormal beliefs. Conclusion: This study confirms the connection of executive brain functions to paranormal beliefs and determines that frontal brain function may contribute to paranormal beliefs. Highlights: Paranormal beliefs were negatively related to the EEG coherence.Paranormal beliefs were associated with EEG coherence in the right frontal lobe.We found a negative correlation between paranormal beliefs and the EEG coherence in the frontal lobes.EEG coherence the frontal lobes predicted paranormal beliefs. Plain Language Summary: Paranormal beliefs were negatively related to the EEG coherence. They were associated with EEG coherence in the right frontal lobe. In this study, we found a negative correlation between paranormal beliefs and the EEG coherence in the frontal lobes. EEG coherence the frontal lobes predicted paranormal beliefs.

The global scientific publications on gut microbiota in type 2 diabetes; a bibliometric, Scientometric, and descriptive analysis.

Background: Modifying gut dysbiosis has achieved great success in managing type 2 diabetes mellitus (T2DM) and also T2DM affected the gut microbial composition. Objectives: To determine the research trend of scientific publications on the relationship between gut microbiota and T2DM through a bibliometric and descriptive approach. Method: We included originals and reviews related to both topics of gut microbiota and T2DM through searching in Scopus up to 31 December 2019 and then characterized their bibliometric profiles including the number of publications, citations, institutions, journals, countries, and the collaboration network of authors, countries, terms and keywords. Moreover, we performed a descriptive evaluation of the clinical trials based on their intervention type and its influence on gut dysbiosis. Results: We achieved 877 articles (436 originals and 441 reviews) according to our inclusion criteria. The annual publications were constantly increased over time and reached 220 publications in 2019. Out of 436 original articles, 231 animal studies and 174 human studies were found. The majority of human studies were clinical trials (n = 77) investigating the influence of drugs (n = 21), regimens (n = 21), pre/pro/symbiotic (n = 19), surgeries (n = 15), or both drug and regimen (n = 1) on gut dysbiosis. Roux-en-Y gastric bypass and metformin were assessed the most in these trials. Obesity side by side T2DM has been assessed in this area of literature based on term and keyword analyses showing their possible similar pathways mediated by gut microbiota. Conclusion: The exponentially growing documents on gut microbiota and T2DM had been published during the last decade and revealed gut microbiota alteration mediated antidiabetic effect of many interventions. Thus, we suggest other researchers to consider this pathway in efficacy assessment of therapeutic modalities and to find the optimal composition of gut microbiota that guarantees healthy insulin sensitivity.

Clinical Presentations of the Survivor and Non-survivor Hospitalized Patients with COVID-19 in the Golestan Province of Iran during the First Peak of the Epidemics.

Background: Considering the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic, which causes coronavirus disease 2019 (COVID-19), we aimed to report the clinical features of 427 patients with COVID-19 and the outcomes after one-month admission to major teaching hospitals in the northeast of Iran. Materials and Methods: Data of patients hospitalized with COVID-19 from 20 February 2020 to 20 April 2020 was analyzed using the R software. The cases and their outcomes were monitored up to one month following their admission. Results: Among 427 patients with a median age of 53 years (50.8% male), 81 (19%) were directly admitted to the ICU ward, and 68 (16%) died during the study. The mean (SD) lengths of hospital stay were significantly higher in the non-survivors (6 (9) days) than survivors (4 (5) days) (P = 0.018). Ventilation need was reported in 67.6% of the non-survivors and 0.8% of the survivors (P < 0.001). Cough (72.8%), fever (69.3%), and dyspnea (64.0%) were the most common symptoms. There were more comorbidities in the severe cases (73.5%) and non-survivor (77.5%). Liver and kidney damage were significantly more common in non-survivors. Ninety percent of the patients had at least one abnormal chest CT scan finding, including crazy paving and consolidation patterns (27.1%), followed by the ground-glass opacity (24.7%). Conclusion: Results showed that the patients' age, underlying comorbidities, levels of SpO2, and laboratory findings at the time of admission may predict the progress of the disease and can be considered mortality-related factors.

COVID-19 prognostic modeling using CT radiomic features and machine learning algorithms: Analysis of a multi-institutional dataset of 14,339 patients.

BACKGROUND: We aimed to analyze the prognostic power of CT-based radiomics models using data of 14,339 COVID-19 patients. METHODS: Whole lung segmentations were performed automatically using a deep learning-based model to extract 107 intensity and texture radiomics features. We used four feature selection algorithms and seven classifiers. We evaluated the models using ten different splitting and cross-validation strategies, including non-harmonized and ComBat-harmonized datasets. The sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) were reported. RESULTS: In the test dataset (4,301) consisting of CT and/or RT-PCR positive cases, AUC, sensitivity, and specificity of 0.83 ± 0.01 (CI95%: 0.81-0.85), 0.81, and 0.72, respectively, were obtained by ANOVA feature selector + Random Forest (RF) classifier. Similar results were achieved in RT-PCR-only positive test sets (3,644). In ComBat harmonized dataset, Relief feature selector + RF classifier resulted in the highest performance of AUC, reaching 0.83 ± 0.01 (CI95%: 0.81-0.85), with a sensitivity and specificity of 0.77 and 0.74, respectively. ComBat harmonization did not depict statistically significant improvement compared to a non-harmonized dataset. In leave-one-center-out, the combination of ANOVA feature selector and RF classifier resulted in the highest performance. CONCLUSION: Lung CT radiomics features can be used for robust prognostic modeling of COVID-19. The predictive power of the proposed CT radiomics model is more reliable when using a large multicentric heterogeneous dataset, and may be used prospectively in clinical setting to manage COVID-19 patients.
