Lifetime exposure to smoking and substance abuse may be associated with late-onset multiple sclerosis: a population-based case-control study.

BACKGROUND: Late-onset multiple sclerosis (LOMS), defined as the development of MS after the age of 50, has shown a substantial surge in incidence rates and is associated with more rapid progression of disability. Besides, studies have linked tobacco smoking to a higher chance of MS progression. However, the role of smoking on the risk of developing LOMS remains unclear. This study aims to evaluate the possible association between lifetime exposure to cigarette and waterpipe smoking, drug abuse, and alcohol consumption and the risk of LOMS. METHODS: This population-based case-control study involved LOMS cases and healthy sex and age-matched controls from the general population in Tehran, Iran. The primary data for confirmed LOMS cases were obtained from the nationwide MS registry of Iran (NMSRI), while supplementary data were collected through telephone and on-site interviews. Predesigned questionnaire for multinational case-control studies of MS environmental risk factors was used to evaluate the LOMS risk factors. The study employed Likelihood ratio chi-square test to compare qualitative variables between the two groups and utilized two independent sample t-test to compare quantitative data. Adjusted odds ratio (AOR) for age along with 95% confidence intervals (CI) were calculated using matched logistic regression analysis in SPSS 23. RESULTS: Totally, 83 LOMS cases and 207 controls were included in the analysis. The female to male ratio in the cases was 1.5: 1. The mean ± SD age of 83 cases and 207 controls was 61.14 ± 5.38) and 61.51 ± 7.67 years, respectively. The mean ± SD expanded disability status scale (EDSS) score was 3.68 ± 2.1. Although the results of waterpipe exposure had no significant effect on LOMS development (P-value: 0.066), ever cigarette-smoked participants had a significantly higher risk of developing LOMS than those who never smoked (AOR: 2.57, 95% CI: 1.44-4.60). Furthermore, people with a history of smoking for more than 20 years had 3.45 times the odds of developing MS than non-smokers. Drug and alcohol abuse were both associated with LOMS in our study; of which opioids (AOR: 5.67, 95% CI: 2.05-15.7), wine (AOR: 3.30, 95% CI: 1.41-7.71), and beer (AOR: 3.12, 95% CI: 1.45-6.69) were found to pose the greatest risk of LOMS, respectively. CONCLUSION: For the first time, we identified smoking, drug, and alcohol use as potential risk factors for LOMS development. According to the global increase in cigarette smoking and alcohol use, these findings highlight the importance of conducting interventional approaches for prevention.

Therapeutic roles of CAR T cells in infectious diseases: Clinical lessons learnt from cancer.

Cancer immunotherapy has made improvements due to the advances in chimaeric antigen receptor (CAR) T cell development, offering a promising treatment option for patients who have failed to respond to traditional treatments. In light of the successful use of adoptive CAR T cell therapy for cancer, researchers have been inspired to develop CARs for the treatment of other diseases beyond cancers such as viral infectious diseases. Nonetheless, various obstacles limit the efficacy of CAR T cell therapies and prevent their widespread usage. Severe toxicities, poor in vivo persistence, antigen escape, and heterogeneity, as well as off-target effect, are key challenges that must all be addressed to broaden the application of CAR T cells to a wider spectrum of diseases. The key advances in CAR T cell treatment for cancer and viral infections are reviewed in this article. We will also discuss revolutionary CAR T cell products developed to improve and enhance the therapeutic advantages of these treatments.

Prediction and interpretation of rare missense variant in OTOG associated with hearing loss.

OTOG encodes for otogelin, a component of the tectorial membrane. This gene is associated with nonprogressive mild-to-moderate hearing loss. However, no studies have yet identified the association between OTOG variation and severe-to-profound hearing loss. Therefore, to address this issue, a family-based whole-exome sequencing strategy (WES) was carried out. Two unrelated Iranian families with non-syndromic hearing loss were identified, and WES was conducted on one selected candidate from each family. As a result, a rare homozygous missense variant, OTOG (c.C2383T:p.R795C), was detected in both of the subjected probands, and segregation analysis confirmed the c.C2383T variant in seven cases of severe-to-profound hearing loss. Additionally, the results from the protein modeling demonstrated that the altered position of a few disulfide bonds in the TIL domain may have a deleterious impact on protein stability and normal functionality. In conclusion, it seems that the homozygosity of the OTOG c.C2383T mutation sheds light on hearing loss pathobiology. Nevertheless, further studies are required to unravel the precise function of OTOG mutation, which is potentially associated with severe-to-profound hearing loss.

Association of ACE Gene Insertion/Deletion Polymorphism with Suicidal Attempt in an Iranian Population.

Deregulation of the renin-angiotensin system (RAS) plays an important role in suicide. Angiotensin converting enzyme (ACE) gene is a key component in this system. The relationship between insertion/deletion (I/D) polymorphism of ACE gene with suicide attempt (SA) is controversial. According to previous studies, allele D in this polymorphism has been considered as a potential risk factor for suicide. However, no study has been conducted in Iran to investigate this matter. This case-control study has focused on investigating the association of ACE I/D polymorphism (rs1799752) with SA in an Iranian population. The frequency of genotypes was 14% for II, 55% for ID, and 31% for DD in the case group (100 persons), and 18% for II, 74% for ID, and 8% for DD in control group (100 persons). Results show there was a significant difference in the distribution of ACE I/D polymorphism genotypes in men with SA compared to controls, as well as in women with SA compared to controls. Also, there was a significant association between DD genotype and the risk of SA compared to II genotype as reference. The severity of depression was significantly different between DD and II genotypes in SA group. According to the results, we suggest that the presence of DD genotype is possibly associated with an increased risk of SA. Maybe part of that is related to severity of depression in DD genotypes carriers of ACE I/D polymorphism.

Study the effect of 24-epibrassinolide application on the Cu/Zn-SOD expression and tolerance to drought stress in common bean.

To study the possibility of increasing the drought tolerance of common bean with the exogenous application of 24-epibrassinolide (EBL), an experiment was conducted in 2016 and 2017. In this experiment, two irrigation levels (optimal irrigation and drought stress) were applied to the main plots and two common bean genotypes (Kusha cultivar and COS16 genotype) and four EBL concentrations (0, 2, 4, and 6 µM) were allocated to sub-plots as factorial. In the flowering stage, drought stress was applied and plants were sprayed with EBL. The results showed that drought stress reduced relative water content (RWC) and increased proline content, malondialdehyde (MDA) content, and antioxidant enzymes activity. However, exogenous application of EBL reduced the seed yield loss and increased the drought stress tolerance in both common bean genotypes by decreasing the MDA content and increasing the RWC, proline content, antioxidant enzymes activity, and nitrate reductase activity. It can be concluded that foliar spray of 4 µM EBL as the best concentration may increase the seed yield and enhance the drought stress tolerance of common bean. Also, Cu/Zn-SOD was up-regulated in response to the drought stress and exogenous EBL. The COS16 genotype showed better response to the drought stress and exogenous EBL than the Kusha cultivar, because of the higher up-regulation of Cu/Zn-SOD in this genotype compared to the Kusha cultivar. Therefore, EBL can be used as a plant growth regulator to enhance drought stress tolerance and minimize the seed yield loss of common bean caused by water deficit.

Quality of life and psychological distress in women with recurrent miscarriage: a comparative study.

BACKGROUND: This study aimed to evaluate quality of life and psychological distress in Iranian women with recurrent miscarriage and to compare it in women without miscarriage. METHODS: This was a comparative study of quality of life among women with and without recurrent miscarriage. Cases were selected from patients with complain of recurrent miscarriage and comparison group were selected from women attending to two teaching hospitals for annual screening. Quality of life (QOL) was measured using the 36-Item Short Form Survey (SF-36). In addition the Hospital Anxiety and Depression Scale (HADS) were used to measure anxiety and depression. Comparison was made between two groups using the independent samples t-test and chi-square. RESULTS: In all 105 women with recurrent miscarriage and 105 healthy women were studied. The socio-demographic status for both groups was similar. Women with recurrent miscarriage showed a significant higher degree of psychological distress [mean (SD) anxiety score was: 10.6 (2.3) vs. 9.1 (2.2), P < 0.0001; and mean (SD) depression score was: 11.0 (2.3) vs. 9.5 (1.9), P < 0.0001]. In addition women with recurrent miscarriage reported significantly lower level of quality of life in all domains (role physical, general health, vitality, social functioning, role emotional, and mental health, all P values < 0.0001), except for physical functioning (P = 0.06) and bodily pain (P = 0.17). CONCLUSION: The findings demonstrated that women with recurrent miscarriage reported extensive functional disability, and lower level of well-being compared to women without recurrent miscarriage. The findings have some implications for prenatal care and suggest that appropriate treatment of recurrent miscarriage is essential.

In Vitro Effect of Luting Cement on Fracture Resistance of Primary Maxillary Central Incisors with Fiber Posts.

Objectives: The use of fiber posts in endodontically treated primary maxillary central incisors improves the retention of composite resin restorations. The purpose of this study was to evaluate the effect of 4 different luting cements on fracture resistance of primary maxillary central incisors with fiber posts. Materials and Methods: In this in vitro study, 40 primary maxillary central incisors were endodontically treated and obturated with Metapex. They were then randomly divided into four groups (n=10) for cementation of fiber posts with GC Fuji I glass ionomer luting cement, Panavia F2.0 dual-cure luting cement, Panavia SA Luting Plus cement (self-adhesive), and TotalCem self-adhesive cement. After 1000 thermal cycles, the fracture resistance was measured. Data were statistically analyzed using ANOVA (alpha=0.05). Results: The mean fracture resistance was 267.07±130.01N in TotalCem, 257.27±102.56N in Panavia F2.0 dual-cure cement, 227.82±110.40N in Panavia SA Luting Plus self-adhesive cement, and 220.89±59.96N in GC Fuji I glass ionomer group. There was no statistically significant difference in fracture resistance among the four groups (P=0.714). Conclusion: Type of luting cement had no significant effect on fracture resistance of primary maxillary central incisors with fiber posts. Nonetheless, TotalCem yielded the highest fracture resistance. Considering its self-adhesive property and easy workability, it can be a good option for cementation of fiber posts in endodontically treated primary central incisors.

Rectal gastrointestinal stromal tumor (GIST) in a patient with Crohn's disease: a rare coincidence case report and brief literature review.

Gastrointestinal stromal tumors (GISTs) are the most common type of gastrointestinal mesenchymal tumors. The most common site for developing these neoplasms is the stomach and small intestine. In contrast, anorectal GISTs are very rare. Population-based studies have shown an increased risk of colorectal cancers (CRC) in patients with Crohn's disease (CD). As in sporadic CRC, adenocarcinomas are the most commonly observed tumor. Accordingly, it is expected that rectal mass in CD patients to be an adenocarcinoma. Some reports have presented CD cases with GISTs along the gastrointestinal tract; however, to the best of our knowledge, a rectal GIST has not been reported in CD. Herein, we report a 41-year-old woman with CD who presented with 8 weeks of constipation and was diagnosed with rectal GIST and briefly review existing reports regarding GIST in IBD.

Opium use and gastrointestinal cancers: a systematic review and meta-analysis study.

Aim: The current systematic review and meta-analysis aimed to assess the association between Gastrointestinal (GI) cancers and opium use. Background: GI malignancies are a global public health issue and are associated with many risk factors including genetic and lifestyle factors. Methods: PubMed, Web of Science, Embase and Scopus and the Google Scholar search engine in addition to Persian databases including Magiran and SID were searched using relevant keywords. The associations of opium use, long duration of opium use, high daily amount opium use and high cumulative opium use and GI cancer and various subtypes of GI cancers were estimated and pooled in format of odds ratios (OR) and their corresponding 95% confidence intervals (CI) with a random effects model. Results: 22 articles that were published between 1983 and 2022 entered the analyses. There were significant relationships between opium use based on crude effect sizes (OR: 2.53, 1.95-3.29) and adjusted effect sizes (OR: 2.64, 1.99-3.51), high daily opium use (or: 3.41, 1.92-6.06), long duration of opium use (OR: 3.03, 1.90-4.84) and high cumulative opium use (OR: 3.88, 2.35-6.41), all compared to never opium use, and GI cancer. The results were not sensitive to sensitivity analyses and no influential publication biases were found in these analyses. Conclusion: Our meta-analysis showed that opium use could be associated with increased risk of overall and some particular GI cancers including oropharyngeal, gastric, pancreatic and colorectal cancers. Opium use as a potentially modifiable factor, therefore, should be more emphasized.

A Rapid Sterility Method Using Solid Phase Cytometry for Cell-Based Preparations and Culture Media and Buffers.

In this article, we demonstrate a rapid sterility testing method for non-filterable cell-based preparations and its in-process control media/buffers. The selected rapid sterility test (RST) in this work is based on the ScanRDI® system, which detects fluorescently labeled microorganisms with solid-phase cytometry. ScanRDI® has been chosen due to its sensitivity for detecting viable microorganisms down to one microbial cell with a shorter time to detection compared with the compendial sterility test (CST) method. The RST was validated for a CAR-T cell-therapy product with 4 days of time to detection (TTD) and evaluated for in-process control of media/buffers with real-time detection method success according to USP <1223>, Ph. Eur. 5.1.6, and PDA Technical Report No. 33. The validation parameters included limit of detection and equivalence in routine operations, specificity, robustness, ruggedness, and repeatability. For the validation, a combination of pharmacopoeial ATCC strains as well as in-house isolates were used. In addition, the evaluation study of this RST for in-process control of media/buffers was assessed by performing the limit of detection and equivalence with four representative microorganisms. Where applicable, results were statistically evaluated to demonstrate equivalence and no significant difference of the rapid method as compared with the CST method have been detected. All acceptance criteria have been met, and the solid-phase cytometry technology was successfully validated as an alternative sterility test for cell-based preparations and for its in-process control of media/buffer.

The inhibitory effect of cannabidiol on the rewarding properties of methamphetamine in part mediates by interacting with the hippocampal D1-like dopamine receptors.

Cannabidiol (CBD) is a potential treatment to decrease the rewarding properties of psychostimulants. However, the exact mechanism and distinct neuroanatomical areas responsible for the CBD's effects remain unclear. Indicatively, the D1-like dopamine receptors (D1R) in the hippocampus (HIP) are essential for expressing and acquiring drug-associated conditioned place preference (CPP). Therefore, given that involving D1Rs in reward-related behaviors and the encouraging results of CBD in attenuating the psychostimulant's rewarding effects, the present study sought to investigate the role of D1Rs of the hippocampal dentate gyrus (DG) in the inhibitory effects of CBD on the acquisition and expression of METH-induced CPP. To this end, over a 5-day conditioning period by METH (1 mg/kg; sc), different groups of rats were given intra-DG SCH23390 (0.25, 1, or 4 µg/0.5 µl, saline) as a D1Rs antagonist before ICV administration of CBD (10 µg/5 µl, DMSO12%). In addition, a different set of animals, after the conditioning period, received a single dose of SCH23390 (0.25, 1, or 4 µg/0.5 µl) before CBD (50 µg/5 µl) administration on the expression day. The results showed that SCH23390 (1 and 4 µg) significantly reduced the suppressive effects of CBD on the acquisition of METH place preference (P < 0.05 and P < 0.001, respectively). Furthermore, the highest dose of SCH23390 (4 µg) in the expression phase remarkably abolished the preventive effects of CBD on the expression of METH-seeking behavior (P < 0.001). In conclusion, the current study revealed that CBD's inhibitory effect on rewarding properties of METH partially acts through D1Rs in the DG area of the HIP.

The effect of Allium saralicum R. M. Fritsch nanocapsules in yogurt on type 2 diabetes in male rats: physicochemical characterization and pharmacodynamics assessment.

To treat illness, people are increasingly turning to natural foods rather than pharmaceuticals. Herbal extracts with antioxidant and anti-diabetic properties could be a good alternative for treating diabetes. The purpose of this study was to look into the effects of ethanol extraction on the Morphology of liver cells and hyperglycemia in rats of Allium saralicum RM Fritsch nanocapsules based on chitosan incorporated with yogurt. In this experimental study, 32 adult Wistar rats were randomly selected. The effect of Nano extraction on hypoglycemia was assessed using blood glucose levels three and fifteen days after a streptozotocin intraperitoneal (60 mg/kg) injection, as well as hepatocyte count and liver tissue morphology. The average size of the chitosan nanoparticles was determined to be 86 nm. After comparing the blood sugar levels of the A. saralicum nanocapsules groups to the untreated diabetes group, a significant decrease was constructed to observe hyperglycemia. Because of increased effective absorption in the intestine, nanocapsules incorporated into yogurt were able to reduce hyperglycemia in diabetic rats. As a result, a new yogurt formulation containing A. saralicum nanocapsules extract is recommended for diabetic patients.

Unusual presentation of transthyretin (ATTR) cardiac amyloidosis: A case report of pruritus as a possible initial symptom and challenging diagnosis.

Key Clinical Message: This case emphasizes the significance of cardiac amyloidosis as a potential diagnosis in individuals manifesting with lesion-free pruritus and normal liver tests. Abstract: Amyloidosis is a complex disorder in which misfolded proteins accumulate in various organs of the body. Cardiac amyloidosis (CA) can lead to heart failure, cardiac arrhythmia, sudden cardiac death, and deposition of proteins in coronary arteries. Diagnosing CA can be difficult, as the cardiac manifestations of amyloidosis can be similar to more prevalent etiologies. In addition, the accumulation of proteins in soft tissues, including the skin, can cause pruritus. In this paper, we present a 70-year-old man with generalized pruritus and no skin lesions, later diagnosed as CA after detecting ascites fluid. This case underscores the importance of considering amyloidosis in patients presenting with nonspecific symptoms, particularly those affecting the skin, and highlights the need for increased awareness of this disease among clinicians.

Cardiac calcified amorphous tumor in a patient with colon cancer.

Although one of the most important differential diagnoses of cardiac masses in cancer patients is metastasis from the underlying tumor, it may also be caused by benign etiologies. In this article, we describe cardiac calcified amorphous tumor, which is one of the benign causes of cardiac masses, in a patient with colon cancer.

Impact of maintenance dose of eptifibatide in patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) is usually caused by a rupture in the atherosclerotic plaque, followed by platelet aggregation which ultimately leads to acute coronary artery occlusion. So far, few studies have investigated the effect of maintenance dose of Eptifibatide (glycoprotein IIb/IIIa inhibitor) in STEMI patients who underwent primary percutaneous coronary intervention (PPCI). Therefore, in this study, we investigated the effect of maintenance dose of Eptifibatide in patients with STEMI who underwent PPCI. 264 patients who had acute chest pain suggestive of STEMI were entered in the study. All patients received the same dose of bolus dose of Eptifibatide in the cardiac catheterization laboratory. Then the patients were randomly divided into two groups, one group (n = 147) received a maintenance dose of intravenous Eptifibatide (infusion of 2 µg/kg/min) and the other group (n = 117) did not receive this treatment. Standard medical treatment of STEMI after PPCI was performed based on guidelines and the same in both groups. All patients were evaluated 1, 2, and 3 months after the start of treatment in terms of predicted outcomes. RESULTS: The occurrence of 3-month major adverse cardiovascular events (MACE) between the case and control groups did not have a statistically significant difference (28.6% versus 35.0%; P value: 0.286). Also, investigations showed that the rate of re-infarction (P value: 0.024) and target lesion revascularization (P value: 0.003) was significantly lower in the group that received Eptifibatide infusion. CONCLUSIONS: Eptifibatide maintenance dose infusion in patients who undergo PPCI in the context of STEMI, does not significantly reduce MACE, although it does significantly reduce re-infarction and target lesion revascularization. It also does not increase the risk of bleeding and cerebrovascular events.

Prevalence of Thromboembolic Events, Including Venous Thromboembolism and Arterial Thrombosis, in Patients with COVID-19: A Systematic Review with Meta-Analysis.

Background: Many studies have evaluated thromboembolic events in COVID-19 patients, and most of them have reported a high estimation of the prevalence of such events. The present study sought to evaluate the prevalence of thromboembolic events in patients with COVID-19. Methods: This study is a systematic review with meta-analysis that investigated thromboembolic events in patients with COVID-19 from the start of the pandemic to August 31, 2021. The 4 main databases for collecting articles were Medline, Scopus, Google Scholar, and Web of Science. Deep vein thrombosis, pulmonary embolism, arterial thrombosis, and the overall rate of thromboembolic events were considered primary outcomes. Results: In a total of 63 studies (104 920 patients with COVID-19), the overall thrombosis rate was 21% (95% CI, 18% to 25%), the rate of deep vein thrombosis was 20% (95% Cl, 16% to 25%), the rate of pulmonary embolism was 8% (95% Cl, 6% to 10%), and the rate of arterial thrombosis was 5% (95% Cl, 3% to 7%). The prevalence of all primary outcomes in critically ill patients admitted to the intensive care unit (ICU) was significantly higher (P<0.05). In older patients, the prevalence of overall thrombosis, pulmonary embolism, or deep vein thrombosis was significantly higher (P<0.05). Conclusion: This study showed that COVID-19 increases the risk of thromboembolic events, especially in elderly and critically ill patients admitted to the ICU. Therefore, more strategies are needed to prevent thromboembolic events in patients with COVID-19, especially in ICU-admitted and elderly patients.

Effect of Photobiomodulation Therapy with 915 nm Diode Laser on Pain Perception during Local Anesthesia of Maxillary Incisors: A Randomized Controlled Trial.

This study aimed to evaluate the effect of photobiomodulation therapy (PBMT) with 915 nm wavelength on pain reduction during maxillary incisors' local infiltration in a randomized clinical trial study. A prospective triple-blinded split-mouth clinical trial was designed to assess pain perception during needle insertion and local anesthetic injection in 32 healthy patients required operative caries management on contralateral maxillary incisors. After laser treatment (915 nm, power of 1.5 W, duty cycle of 60% and energy density of 72 J cm^-2 ) in active group and no irradiation in sham group, the injection was performed. Patients' perception of pain was immediately assessed using numerical rating scale (NRS) for pain. Washout period between two appointments was one week. Wilcoxon signed-rank and Pearson correlation statistical analyses were used to assess the comparison of pain score between two appointments and the effect of anxiety level of previous dental injections. The mean scores of pain for the active laser and sham laser groups were 2.5 ± 2.19 and 4.34 ± 2.52, respectively, with a statistically significant higher NRS in the sham laser group (P ˂ 0.05). In this study's condition, diode PBMT reduced pain during infiltration on maxillary incisors. Anxiety experience of dental injection had no significant effect on pain perception scale (P ˃ 0.05).

Co-Expression Network Analysis of Soybean Transcriptome Identify Hub Genes Under Saline-Alkaline and Water Deficit Stress.

Background: Soybean is an important oilseed crop that its development and production are affected by environmental stresses (such as saline-alkaline and water deficit). Objectives: This experiment was performed with the aim of identifying candidate genes in saline-alkaline stress and water-deficit stress conditions using transcriptome analysis and to investigate the expression of these genes under water deficit stress conditions using RTqPCR. Materials and Methods: In this experiment, soybean transcriptome data under saline-alkaline and water-deficit stress were downloaded from the NCBI website, and then the co-expression modules were determined for them and the gene network was plotted for each module, and finally, the hub genes were identified. To compare the expression of genes in saline-alkaline and water deficit conditions, soybean plants were subjected to water deficit stress and their gene expression was determined using RTqPCR. Results: The filtered (Log FC above +2 and below -2) genes of soybean were grouped under saline-alkaline stress in 15 modules and under water-deficit stress in 2 different modules. Within each module, the interaction of genes was identified using the gene network, then three genes of ann11, cyp450 and zfp selected as hub genes. These hub genes are highly co-expression with other network genes, which not only display differential expression but also differential co-expression. The results of RT-PCR indicated that cyp450 gene expression was not significantly different from the control, while ann11 gene expression significantly increased under water deficit stress, but zfp gene expression decreased significantly under water deficit stress. Conclusions: We identified three genes, ann11, cyp450 and zfp, as hub genes. According to our results, ann11 gene had a significant increase in expression under water deficit stress, which can indicate the importance of this gene under drought conditions. Therefore, according to the results of this experiment as well as other researchers, we introduce this gene as a key gene in water deficit tolerance and recommend its use in genetic engineering to increase the tolerance of other plants.

The efficacy of transdiagnostic cognitive behavioural therapy on reducing negative affect, anxiety sensitivity and improving perceived control in children with emotional disorders - a randomized controlled trial.

In response to the high rate of comorbidity among different types of emotional disorders in children, Transdiagnostic Unified Protocol of Emotional disorder in children (UP-C) was developed to address common underlying mechanisms in the development and maintenance of emotional disorders using empirically supported cognitive and behavioural strategies. Although, studies supported the effectiveness of this protocol in the treatment of wide range of emotional disorders, further studies are needed to examine its effect on transdiagnostic factors. The present study aimed to investigate the efficacy of the UP-C on negative affect, anxiety sensitivity and perceived control in children with emotional disorders. During this randomized controlled trial, 34 children aged 7 to 13 with emotional disorders were randomly assigned to treatment (n=18) and control (n=16) groups. The treatment group and their parents received 15 sessions of UP-C. Negative Affect Schedule for Children (PANASNA- C), Children's Anxiety Sensitivity Index (CASI), Anxiety Control Questionnaire-Children (ACQ-C) were carried out in all phases (pre-treatment, post-treatment, 3 and 8 months follow- up). The results showed that following UP-C, negative affect (hedges'g=2.01) and anxiety sensitivity (hedges'g=1.05) were significantly reduced, and perceived control (hedges'g= -2.36) was significantly improved. The results remained relatively constant during the follow-ups. Findings provide evidence that the UP-C has significant effect on negative affect, anxiety sensitivity and perceived control as roots of emotional disorders.

Comparison of portal hypertensive gastropathy and gastric antral vascular ectasia: an update.

Portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE) are two distinct entities that are frequently mistaken with each other, because they present with similar manifestations. This issue may cause catastrophic outcomes, as each one of them has a unique pathophysiology, thereby making their management approaches completely different. There are clinical clues that help physicians distinguish these two. Direct vision via upper endoscopy is often mandatory to establish the diagnosis, and sometimes biopsy is required. In this review, we sought to discuss different aspects of both conditions and highlight clinical evidence that may help in identifying and managing the disease appropriately.
