The present study examined the extent to which the currently established factor structure of the Personality Inventory for DSM-5 (PID-5; Krueger et al., 2013) generalizes to a large Persian community sample, as well as relations between the resulting PID-5 factors and two temperament measures. Cross-sectional data came from 946 adults (65% female) from western Iran. With the use of exploratory structural equation modeling (ESEM) with target rotation, we found factor loadings that showed fairly similar patterns to those found in two previous meta-analytic PID-5 studies with predominantly North American and European samples (Watters & Bagby, 2018; Somma et al., 2019). Despite slight differences in each of the target rotations, there were moderate congruence coefficients (~0.85) between loadings for the five PID-5 domains, with the weakest evidence supporting the Disinhibition factor. The resulting PID-5 factors showed meaningful associations with temperament domains assessed via the Temperament and Character Inventory (TCI; Cloninger, 1994) and Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A; Akiskal et al., 2005). Overall, our findings suggest that the documented structure of personality pathology assessed by the PID-5 generalizes somewhat to this sample of Persian participants, and pathological personality traits show important overlap with temperament, although these constructs are meaningfully distinct., (© 2024 John Wiley & Sons Ltd.)

Purpose: Evaluate safety and efficacy of 0.75% phentolamine ophthalmic solution (POS), an alpha-1 antagonist, in reversal of pharmacologically induced mydriasis., Design: Two Phase 3, multicenter, placebo-controlled, randomized, double-masked clinical trials in healthy subjects., Subjects: 553 healthy 12 to 80 year old subjects were randomized 1:1 (MIRA-2) and 2:1 (MIRA-3) to receive either POS or placebo eye drops OU., Methods: Subjects received POS or placebo administered 1 hour after mydriasis, induced by instillation of either 2.5% phenylephrine, 1% tropicamide, or Paremyd (1% hydroxyamphetamine / 0.25% tropicamide)., Main Outcome Measures: Primary endpoint was percent of subjects returning to ≤0.2 mm greater than baseline pupil diameter in study eye at 90 minutes after POS administration. Safety measures included treatment-emergent adverse events (TEAEs) and tolerability measures, including conjunctival hyperemia., Results: In MIRA-2, 185 subjects were randomized to treatment with placebo (94) or POS (91). In MIRA-3, 368 subjects were randomized to treatment with placebo (124) or POS (244). A statistically significant greater percentage of subjects treated with POS had study eyes that showed reversal of mydriasis at 90 minutes (primary endpoint) compared with the placebo treatment (48.9% vs 6.6% for MIRA-2; p<0.0001 and 58% VS 6% for MIRA-3; p<0.0001) and as early as 60 minutes (24.5% vs 5.5% for MIRA-2; p<0.0003 and 42% VS 2% for MIRA-3; p<0.0001). Between 28 to 34% of placebo-treated subjects had not returned to baseline PD at 24 hours following pharmacological dilation compared to 8 to 11% treated with POS (p<0.0001)., Conclusion: POS treatment had a rapid onset in reducing PD within 60- to 90-minutes, with a statistically significant time savings of 3 to 4 hours to return to baseline PD compared to placebo. One or 2 drops of POS rapidly reversed mydriasis in all subjects regardless of mydriatic agent or iris color. More subjects receiving POS reported a perceived benefit in the resolution of visual symptoms caused by pharmacologically induced mydriasis compared to placebo, with statistically significant differences noted as early as 1 hour. The safety profile was favorable, with the most common adverse effects being mild transient conjunctival hyperemia (11.2%), instillation site discomfort (10.9%), and dysgeusia (3.6%)., (Copyright © 2024.

Background: Pregnancy is a critical time for women, making them more susceptible to infectious diseases like COVID-19. This study aims to determine the immunogenicity of COVID-19 in pregnant women who have been infected compared to those who have received the inactive COVID-19 vaccine., Materials and Methods: In this retrospective cohort study, pregnant women who received the inactivated COVID-19 vaccine (Sinopharm) and those with a history of COVID-19 infection during pregnancy were studied. Participants who had experienced stillbirth, received different COVID-19 vaccines, or had intrauterine fetal death were excluded from the study. Overall, the study included 140 participants. The participants were divided into two groups of 70 participants - pregnant women who received the Sinopharm vaccine and pregnant women who had COVID-19 infection during pregnancy. Before delivery, blood samples were collected from all mothers to evaluate the maternal immunoglobulin G (IgG) level. Blood samples were also taken from the baby's umbilical cord during delivery to measure the newborn's IgG level. Additionally, blood samples were collected from babies whose mothers showed signs of acute infection to measure their IgM levels and evaluate vertical transmission., Findings: The study found a significant relationship between the mean level of maternal IgG and umbilical cord IgG within the groups (P < 0.001). The highest levels of maternal IgG (2.50 ± 2.17) and umbilical cord IgG (2.43 ± 2.09) were observed in pregnant women with a previous COVID-19 infection and no history of vaccination (P < 0.001). Only one baby was born with a positive IgM, and this baby was born to a mother who showed signs of COVID-19 infection in the last five days of pregnancy. The mother was 28 years old, with a BMI of 33; it was her first pregnancy, and she gave birth to a male newborn at term., Conclusion: Administering an inactivated vaccine during pregnancy can generate immunity in both the mother and the child. However, the vaccine's immunity level may not be as potent as that conferred by COVID-19 infection during pregnancy. Nonetheless, the risk of vertical transmission of COVID-19 is considered minimal and can be classified as negligible., (© 2024. The Author(s).)

Irreversible adsorption, or heel buildup, negatively impacts activated carbon performance and shortens its lifetime. This study elucidates the interconnections between flow rate and the oxygen impurity of desorption purge gas with heel buildup on beaded activated carbon (BAC). Nine thermal desorption scenarios were explored, varying nitrogen purge gas oxygen impurity levels (<5 ppmv, 10,000 ppmv, 210,000 ppm (21 %)) and flow rates (0.1, 1, 10 SLPM or 1 %, 10 %, 100 % of adsorption flow rate) during thermal desorption. Results reveal that increasing purge gas flow rate improves adsorption capacity recovery and mitigates adverse effects of purge gas oxygen impurity. Cumulative heel increased with higher purge gas oxygen impurity and lower flow rates. In the least effective regeneration scenario (0.1 SLPM N 2 , 21 % O 2 ), a 32.8 wt% cumulative heel formed on BAC after five cycles, while the best-case scenario (10 SLPM N 2 , <5 ppmv O 2 ) resulted in only 0.3 wt%. Comparing the pore size distributions of virgin and used BAC shows that heel initially forms in narrow micropores (<8.5Å) and later engages mesopores. Thermogravimetric analysis (TGA) showed that oxygen impurity creates high boiling point and/or strongly bound heel species. TGA confirmed that higher purge gas flow rates reduce heel amounts but encourage chemisorbed heel formation in oxygen's presence. These findings can guide optimization of regeneration conditions, enhancing activated carbon's long-term performance in cyclic adsorption processes., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests Zaher Hashisho reports financial support was provided by Ford Motor Company., (Copyright © 2024.

INTRODUCTION: Respiratory Distress Syndrome (RDS) is the most common respiratory disorder among premature infants. The use of surfactant has significantly reduced respiratory complications and mortality. There are two conventional methods for administering surfactant: Intubate-Surfactant-Extubate (INSURE) and Less Invasive Surfactant Administration (LISA). This study aims to compare the effects of surfactant administration using these two methods on the treatment outcomes of premature newborns. MATERIALS AND METHODS: In this retrospective cohort study, we included 100 premature newborns with RDS and spontaneous breathing who were admitted to the Neonatal Intensive Care Unit of Besat Hospital in Sanandaj city in 2021. Exclusion criteria comprised congenital anomalies and the needing for intubation for resuscitation at birth. The outcomes of empirically treated with two methods were compared: the LISA (50 neonates) and the INSURE (50 neonates). Our interesting outcomes were needing for mechanical ventilation, duration of medical ventilation, pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia. Finally, we entered the data into STATA-14 statistical software and analyzed it using chi-square and t-tests. RESULTS: In this study, 69% of the neonates were boys. The LISA group exhibited significantly lower rates of need for mechanical ventilation (P = 0.003) and ventilation duration (P < 0.001) compared to the INSURE group. Conversely, there were no significant differences between the two groups (P > 0.05) in terms of pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia rates. CONCLUSION: The results of this study suggest that the LISA method is a safe and non-invasive approach for surfactant administration. Notably, it resulted in a reduced need for mechanical ventilation and decreased ventilation duration compared to the INSURE method. [ABSTRACT FROM AUTHOR]

Kawasaki affects the middle-size arteries, especially the coronary arteries. Therefore, without adequate treatment, it may cause coronary artery aneurysm in 25% of patients. The purpose of this study was to investigate the relationship between Kobayashi, Sano, and Egami criterions with coronary artery aneurysm in KD patients during the last ten years and to identify risk factors in patients with intravenous immunoglobulin (IVIG)-resistant and coronary artery aneurysms.Methodology: Medical records of 363 Kawasaki patients referred during 2008– 2017 were reviewed. Patients’ demographic data and Kobayashi, Sano, and Egami scores of each patient were calculated. Based on echocardiographic findings, cases of coronary artery aneurysm were determined. Sensitivity, specificity, positive and negative predictive value, and the accuracy of each criterion were determined to predicting IVIG resistance and detect coronary artery aneurysm.Results: There was a slight relationship between IVIG-resistance in Kawasaki children and its prediction based on the Kobayashi risk score, but no relationship was found between the Egami and Sano criteria. Sixty-three patients (17.4%) had coronary artery lesions (CALs) on time of diagnosis. There were no statistically significant differences between gender and mean age of children with and without CALs. Also, there was no significant relationship between coronary artery aneurysm in Kawasaki children and its prediction based on the above three risk factors. The area under the ROC-curve of all three risk measures of Kobayashi, Egami, and Sano indicated that all three criteria were not useful in predicting CALs.Conclusion: Despite the low accuracy of the three above criteria to predictive of patients with IVIG resistance, it seems that the variables of age, duration of fever, and C-reactive protein (CRP) are more useful than other variables and may be utilized to evaluate patients by establishing a more appropriate cut-off point.Keywords: Kawasaki disease, coronary artery aneurysm, IVIG-resistant, Kobayashi, Sano, Egami

Background: Female sex workers (FSWs) in most societies run a high risk of health problems, including sexually transmitted infections (STIs) such as viral infections and syphilis. The present study examines the prevalence of viral infections and syphilis among FSWs., Methods: This cross-sectional study recruited 100 female sex workers (April 2019 to April 2020) who visited the Counseling Center for Behavioral Diseases or were selected via purposeful (snowball) sampling. A questionnaire (demographic information and STI risk factors) was completed in a face-to-face interview with the participants. Blood samples were then taken to test the markers for HBV, HCV Ab, HIV Ab, Rapid Plasma Reagin (RPR) for syphilis and a PCR was taken to test for HPV (in vaginal sex workers from the cervix and anal sex workers from the anal region). The data were analyzed in Stata 14., Results: Among 100 FSWs, 6 (6%) were infected with HIV, 1 (1%) with hepatitis B, and 2 (2%) were anti-HCV positive. 1 (1%) participant was suspected of having syphilis. Based on the PCR tests, 16 (16%) participants were infected with HPV. Moreover, 68 (68%) FSWs reported having unprotected sex., Conclusion: Due to the prevalence of viral infections and syphilis and unprotected sex in FSWs, immediate preventive measures are critical for this vulnerable group to control the transmission of these viral infections in society., Competing Interests: No potential conflict of interest was reported by the authors., (© The Author(s).)

Introduction: The last decade has seen the increased prevalence of obesity as a public health challenge, particularly in low- and middle-income countries. At the same time, studies have shown that there is a two-way relationship between low-calorie diets and depression in obese individuals. This study was designed and implemented to investigate the effect of a low-calorie high-protein diet on psychometric variables in obese individuals., Materials and Methods: The present study is a Randomized Clinical Trial. Individuals meeting the inclusion criteria were randomly assigned to either the intervention group (low-calorie diet with increased protein percentage) or the control group (standard protein percentage) using block stratification. Psychometric characteristics of the participants were evaluated using the DASS-21 questionnaire., Results: There were no significant differences in enrollment between the two groups with respect to anthropometric variables, body composition, and physical activity ( p -value > .05). Similarly, no significant differences were observed between the two groups in terms of psychological variables (depression, anxiety and stress) ( p -value > .05). However, the intervention groups had significantly lower depression and anxiety scores 15 days into the intervention ( p -value < .05). After 30 and 60 days of intervention, significant differences were observed between the 2 groups in terms of depression, stress, and anxiety ( p -value < .05), indicating a relative improvement in psychometric variables in the intervention group ( p -value < .05)., Conclusion: The results of this study showed that low-calorie diets with a high-protein percentage can significantly improve psychometric variables in obese people.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20221101056371N1..

The development of biomaterials capable of regulating cellular processes and guiding cell fate decisions has broad implications in tissue engineering, regenerative medicine, and cell-based assays for drug development and disease modeling. Recent studies have shown that three-dimensional (3D) nanoscale physical cues such as nanotopography can modulate various cellular processes like adhesion and endocytosis by inducing nanoscale curvature on the plasma and nuclear membranes. Two-dimensional (2D) biochemical cues such as protein micropatterns can also regulate cell function and fate by controlling cellular geometries. Development of biomaterials with precise control over nanoscale physical and biochemical cues can significantly influence programming cell function and fate. In this study, we utilized a laser-assisted micropatterning technique to manipulate the 2D architectures of cells on 3D nanopillar platforms. We performed a comprehensive analysis of cellular and nuclear morphology and deformation on both nanopillar and flat substrates. Our findings demonstrate the precise engineering of single cell architectures through 2D micropatterning on nanopillar platforms. We show that the coupling between the nuclear and cell shape is disrupted on nanopillar surfaces compared to flat surfaces. Furthermore, our results suggest that cell elongation on nanopillars enhances nanopillar-induced endocytosis. We believe our platform serves as a versatile tool for further explorations into programming cell function and fate through combined physical cues that create nanoscale curvature on cell membranes and biochemical cues that control the geometry of the cell.

Vadood Javadi Parvaneh, Mohsen Jari, Saeideh Qhasemi, Mohammad Mahdi Nasehi, Khosro Rahmani, Reza ShiariMofid Children’s Hospital, Shahid Beheshti Medical University of Sciences, Tehran, IranBackground: Systemic lupus erythematosus (SLE) is an autoimmune disease which involves multiple organs, including peripheral nervous system.Case presentation: We describe a 12-year-old boy with progressively worsening neurological symptoms as first manifestation. Legs pain, loss of balance, and lower extremity weakness were the reason for his admission in neurologic ward. The patient was started on intravenous immunoglobulin therapy due to the possibility of Guillain–Barre syndrome and acute inflammatory demyelinating polyneuropathy (AIDP). However, there was no appropriate response and he developed recurrent attacks of polyneuropathy again with diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP). Then, he received intravenous pulse of methylprednisolone for 5 consecutive days followed by oral prednisolone for 3 months. One month after withdrawal of corticosteroid he admitted again with the same manifestations. Rheumatologic workup revealed the presence of leukopenia, hemolytic anemia, hematuria, proteinuria, positive antinuclear antibodies, and ds-DNA antibodies. On the basis of the American College of Rheumatology and Systemic Lupus International Collaborating Clinics Classification Criteria for SLE, the patient had underlying diagnosis of SLE. Eventually, he was treated by the pulse of methylprednisolone and cyclophosphamide, and oral hydroxychloroquine and prednisolone. His neurological and physical symptoms improved and complete neurological recovery occurred several months later.Conclusion: SLE and AIDP/CIDP are different entities, but ADP/CIDP can be part of the neurologic manifestations of the SLE. Although the association between AIDP/CIDP and SLE is very rare especially as a first manifestation of SLE, it should be early recognized for rapid appropriate treatment.Keywords: Guillain–Barre syndrome, chronic inflammatory demyelinating polyneuropathy, systemic lupus erythematosus, nerve disorders

Environmental factors such as ultraviolet radiation, viral infections, drugs, hormones, and chemicals could trigger SLE flares in genetically predisposed patients.Case report: We presented a 13-year-old girl with the first presentation of systemic lupus erythematosus triggered by a mosquito bite. She presented with a malar rash started after a mosquito bite on her left cheek. She had oral ulcers, photosensitivity, lymphopenia, proteinuria, and positive serologic tests for SLE. Renal biopsy revealed class II lupus nephritis.Conclusion: Environmental factors can trigger the onset of SLE in genetically susceptible cases. Besides microbial agents, UV radiation, hormones, drugs, emotional stresses, immunization, and chemicals are some of the published examples. We presented a case with a mosquito bite as the possible environmental trigger.Keywords: mosquito bite, systemic lupus erythematosus, children, pediatrics, etiology, case report

Today, the construction of scaffolds promoting the differentiation of stem cells is an intelligent innovation that accelerates the differentiation toward the target tissue. The use of calcium and phosphate compounds is capable of elevating the precision and efficiency of the osteogenic differentiation of stem cells. In this research, osteoconductive electrospun poly (ɛ-caprolactone) (PCL) - poly (vinyl alcohol) (PVA) hybrid nanofibrous scaffolds containing modified cockle shell (CS) nanopowder were prepared and investigated. In this regard, the modified CS nanopowder was prepared by grinding and modifying with phosphoric acid, and it was then added to PVA nanofibers at different weight percentages. Based on the SEM images, the optimum content of the modified CS nanopowder was set at 7 wt %, since reaching the threshold of agglomeration restricted this incorporation. In the second step, the PVA-CS7 nanofibrous sample was hybridized with different PCL ratios. Concerning the hydrophilicity and mechanical strength, the sample named PCL50-PVA50-CS7 was ultimately selected as the optimized and suitable candidate scaffold for bone tissue application. The accelerated hydrolytic degradation of the sample was also studied by FTIR and SEM analyses, and the results confirmed that the mineral deposits of CS are available approximately 7 days for mesenchymal stem cells. Moreover, Alizarin red staining illustrated that the presence of CS in the PCL50-PVA50-CS7 hybrid nanofibrous scaffold may potentially lead to an increase in calcium deposits with high precipitates, authenticating the differentiation of stem cells towards osteogenic cells., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Background: There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra., Methods: A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported., Results: The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder., Conclusions: A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© 2024 The Author(s).)

Background: Road traffic accidents (RTAs) are predicted to become the world's seventh leading cause of death by 2030. Given the significant impact of RTAs on public health, effective hospital preparedness plays a pivotal role in managing and mitigating associated health and life-threatening issues. This study aims to meticulously evaluate the preparedness of selected hospitals in western Iran to handle road traffic accidents with mass casualties (RTAs-MC)., Methods: The study employed a descriptive-analytical approach, utilizing a reliable and valid questionnaire to measure hospitals' preparedness levels. Descriptive statistics (frequency distribution and mean) were utilized to provide an overview of the data, followed by analytical statistics (Spearman correlation test) to examine the relationship between hospital preparedness and its dimensions with the hospital profile. Data analysis, performed using SPSS software, categorized preparedness levels as weak, moderate, or high., Results: The study found that hospitals in Kurdistan province had a favorable preparedness level (70.30) to respond to RTAs-MC. The cooperation and coordination domain had the highest preparedness level (98.75), while the human resource management (59.44) and training and exercise (54.00) domains had the lowest preparedness levels. The analysis revealed a significant relationship between hospital preparedness and hospital profile, including factors such as hospital specialty, number of beds, ambulances, staff, and specialized personnel, such as emergency medicine specialists., Conclusion: Enhancing preparedness for RTAs-MC necessitates developing response plans to improve hospital profile, considering the region's geographic and topographic features, utilizing past experiences and lessons learned, implementing of Hospital Incident Command System (HICS), providing medical infrastructure and equipment, establishing communication channels, promoting cooperation and coordination, and creating training and exercise programs., (© 2024.

Introduction and Objectives: Henoch Schönlein purpura (HSP) and Kawasaki disease (KD) are two main inflammatory diseases among childhood vasculitis. Considering the anti-inflammatory effects of 25-hydroxyvitamin D3, we decided to investigate the association of serum 25-hydroxy vitamin D3 level with the type and severity of these conditions., Materials and Methods: The present study was performed as a historical cohort of 254 affected children with KD and HSP vasculitis. The required data were extracted, using a researcher-made questionnaire from patients' electronic file, and then they were analyzed after collecting information of the patients., Results: In HSP group, 54% of participants were boys. Similarly, in KD group, boys were more affected than girls. The comparative 25-hydroxyvitamin vitamin D3 level in HSP patients with and without renal involvement (P=0.02), hematuria (P=0.14), and in two groups with and without heart disease, and also with and without coronary artery dilatation in KD patients (P<0.001) were significant., Discussion and Conclusions: The findings showed that insufficient level of vitamin D3 were significantly associated with the exacerbation of complications of both diseases, and therefore it seems that vitamin D deficiency can be an effective predictive factor of severity in HSP and KD patients., (Copyright © 2024.

Background: In Iran, there is a lack of information and studies on acute rheumatic fever (ARF), a global health issue. The limited understanding of ARF's prevalence and primary clinical symptoms has led to confusion. This research investigates the characteristics of children aged 3-17 years who experience ARF with monoarthritis as their initial symptom., Methods: A retrospective evaluation of medical records of children diagnosed with ARF was conducted. The study aimed to determine the prevalence of monoarthritis as the first manifestation of ARF and its association with age, gender, family history, and cardiac involvement. Categorical variables were analyzed using the chi-square test with a significance level of < 0.05 and a confidence interval of 95%, using SPSS software (Version 23)., Results: The study included 62 patients with ARF, comprising 41 (66.1%) boys with an average age of 8.48±3.27 years. Among these patients, 12 exhibited cardiac involvement according to the revised Jones criteria, with 5 clinical carditis and 7 cases of subclinical carditis. Monoarthritis was the initial symptom in seven patients (11.29%); five (71.4%) also had carditis. There was a significant association ( p<0.001 ) between monoarthritis and carditis., Conclusion: The study concludes that monoarthritis may be an early sign of ARF in children and correlates significantly with cardiac involvement. However, more extensive research with more significant participant numbers is necessary to understand ARF in Iran comprehensively. A thorough cardiac examination is also crucial for patients with ARF and monoarthritis., Competing Interests: The authors declare that they have no competing interests., (© The Author(s).)

Background: Renal involvement is the most damaging long-term complication of Immunoglobulin-A (IgA) vasculitis. In the lack of a definite predictive biomarker for renal involvement, antiphospholipid antibodies (aPL) have been proposed in recent years., Methods: In this prospective cohort of 48 pediatric patients who were admitted with IgA vasculitis from September 2015 to June 2017, two serum samples were taken 12 weeks apart to detect Anti-Phospholipid antibodies. All patients were followed-up for renal involvement for six months., Results: Renal involvement occurred in 14 out of 48 patients with IgA vasculitis (29.16%). APLs were positive in nine out of 14 patients with IgA vasculitis and renal involvement (64.28%), in contrast to only six out of 34 patients with IgA vasculitis without renal involvement (17.64%). The presence of aPL antibodies was statistically associated with renal involvement (P=0.002). Although, the relationship between both sex (P=0.025) and age (P=0.046) with aPL positivity was statistically significant, performing a modified logistic regression test, the odds ratio was significant between the groups with and without renal involvement only in term of age and aPL positivity)., Conclusion: The presence of aPL antibodies was statistically associated with renal involvement. We found a significant relationship between the age and aPL positivity. Hence, we need multicenter, more extensive cohort studies to reach a better and more accurate conclusion on the relationship between serum aPLs and renal involvement in IgA vasculitis patients., Competing Interests: The authors report no conflicts of interest regarding this manuscript. None of the authors, nor their institutions, received any payment or services from a third party for any aspect of the submitted work., (© The Author(s).)

In this study, the effect of the compaction velocity as well as the size and volume content of the reinforcing particles on the thermal properties of Mg-B4C composites were evaluated. B4C reinforcing particles at various percentages (0, 5, 10%) and two sizes (micron-scale and nanoscale) were added to the magnesium matrix using a planetary ball mill and compacted at 450 °C and three different compaction velocities. The Instron device was utilized for the quasi-static compaction of the powder particles while a drop-hammer and a Split-Hopkinson bar were used for the dynamic compaction of composite powders at medium and high strain rates, respectively. The thermal behavior of the composites was studied by measuring their thermal conductivity and coefficient of thermal expansion. The results showed improvement in dimensional stability of the composites with increasing the volume percentage of the reinforcing particles. Higher compaction velocities led to higher thermal conductivity and coefficient of thermal expansion. Besides, further addition of the reinforcing particles to the matrix resulted in a decrease in the thermal properties. Magnesium samples reinforced with B4C nanoparticles exhibited superior thermal properties compared to those reinforced with micron-sized particles. [ABSTRACT FROM AUTHOR]

Frameworks have been developed to standardize the assessment of carcinogenic potential in the pharmaceutical and agrochemical industries, building upon decades of research. Carcinogenicity is also evaluated during the safety evaluation of food substances, using a comprehensive approach unique to each substance. To better understand these approaches, a retrospective assessment was conducted on the publicly available database of substances notified to the United States Food and Drug Administration (US FDA) as being Generally Recognized As Safe (GRAS). The data contained within these GRAS notifications (GRNs) were reviewed for the methods used to evaluate carcinogenic potential (genotoxicity studies, 2-year bioassays, other pre-clinical animal studies) to identify patterns that could provide an understanding of how this assessment has been conducted for different categories of food substances. While different approaches to the safety evaluation were required to adapt to the unique food substances, the data in all notifications supported the conclusion of safety. The evaluation of food substances for carcinogenic potential must consider all available data, including identifying the need for when more data must be generated to support an evaluation. Due to the complexity of substances used in food, ranging from defined chemical entities to minimally processed agricultural commodities to live microorganisms, the approach to conducting the safety evaluation of food substances must be able to adapt to the most relevant scientifically supported approach. This paper illustrates the data commonly used to support the safety of different types of food substances and proposes an approach familiar to other product sectors., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Khatera Rahmani is a full-time employee of Mars, Incorporated.

Introduction: Respiratory Distress Syndrome (RDS) is the most common respiratory disorder among premature infants. The use of surfactant has significantly reduced respiratory complications and mortality. There are two conventional methods for administering surfactant: Intubate-Surfactant-Extubate (INSURE) and Less Invasive Surfactant Administration (LISA). This study aims to compare the effects of surfactant administration using these two methods on the treatment outcomes of premature newborns., Materials and Methods: In this retrospective cohort study, we included 100 premature newborns with RDS and spontaneous breathing who were admitted to the Neonatal Intensive Care Unit of Besat Hospital in Sanandaj city in 2021. Exclusion criteria comprised congenital anomalies and the needing for intubation for resuscitation at birth. The outcomes of epmericaly trated with two methods were compared: the LISA (50 neonates) and the INSURE (50 neonates). Our interesting outcomes were needing for mechanical ventilation, duration of ventilation, pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia. Finally, we entered the data into STATA-14 statistical software and analyzed it using chi-square and t-tests., Results: In this study, 69% of the neonates were boys. The LISA group exhibited significantly lower rates of need for mechanical ventilation (P = 0.003) and ventilation duration (P < 0.001) compared to the INSURE group. Conversely, there were no significant differences between the two groups (P > 0.05) in terms of pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia rates., Conclusion: The results of this study suggest that the LISA method is a safe and non-invasive approach for surfactant administration. Notably, it resulted in a reduced need for mechanical ventilation and decreased ventilation duration compared to the INSURE method.

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., Competing Interests: The authors declare no competing financial interests., (© 2024, Gastroenterology and Hepatology From Bed to Bench (GHFBB).)

Background: The significant role of red blood cell distribution width (RDW) and D-Dimer as prognostic factors in patients with some blood malignancies has been reported recently., Aim: We designed and performed a meta-analysis to investigate the prognostic roles of RDW and D-Dimer in subjects with diffuse large B-cell lymphoma (DLBCL)., Materials and Methods: We systematically reviewed PubMed-Medline, SCOPUS, EMBASE, Web of Science Core Collection, and Google Scholar up to the present to look for publications on prognostic effects of RDW and D-Dimer in DLBCL patients. For investigation of the associations between RDW and D-Dimer with the overall survival (OS) and progression-free survival (PFS) of the DLBCL cases, hazard ratio (HR) with 95% confidence intervals (CIs) was used., Results: We included 13 eligible studies in the present meta-analysis. The results of pooled analysis showed that increased levels of RDW was related to poor OS (HR = 2.01, 95% CI: 1.62-2.48, p value <.01, I 2  = 0%) and poor PFS (HR = 1.52, 95% CI: 1.24-1.85, p value <.01, I 2  = 16%) among the DLBCL patients. Similarly, a significant relationship was found between increased D-Dimer and poor OS (HR = 2.30, 95% CI: 1.03-5.14, p value <.05, I 2  = 95%) of the DLBCL patients as well. In addition, there was no significant heterogeneity in OS (p value H = 0.65) and PFS (p value H = 0.31) related to RDW among studies included in the meta-analysis., Conclusion: Our finding clearly confirmed that elevated RDW levels and D-Dimer were associated with adverse OS and PFS in DLBCL., (© 2023 The Authors.

Backgrounds: Previous studies have indicated that users' health information-seeking behavior can serve as a reflection of current health issues within a community. This study aimed to investigate the online information-seeking behavior of Iranian web users on Google about Henoch-Schönlein purpura (HSP)., Methods: Google Trends (GTr) was utilized to collect big data from the internet searches conducted by Iranian web users. A focus group discussion was employed to identify users' selected keywords when searching for HSP. Additionally, keywords related to the disease's symptoms were selected based on recent clinical studies. All keywords were queried in GTr from January 1, 2012 to October 30, 2022. The outputs were saved in an Excel format and analyzed using SPSS., Results: The highest and lowest search rates of HSP were recorded in winter and summer, respectively. There was a significant positive correlation between HSP search rates and the terms "joint pain" (P = 0.007), "vomiting" (P = 0.032), "hands and feet swelling" (P = 0.041) and "seizure" (P < 0.001)., Conclusion: The findings were in accordance with clinical facts about HSP, such as its seasonal pattern and accompanying symptoms. It appears that the information-seeking behavior of Iranian users regarding HSP can provide valuable insights into the outbreak of this disease in Iran., (© 2023. The Author(s).)

Background: If somatization is an independent personality trait, it is not clear whether it is specific to the temperament or maladaptive spectrum of personality. We aimed at the head-to-head comparison of temperament and maladaptive systems and spectra of personality to predict both somatization and somatic symptom and related disorders (SSRD)., Methods: The samples included 257 cases with SSRD (70.8% female) and 1007 non-SSRD (64.3% female) from Western Iran. The Personality Inventory for DSM-5 (PID-5), Personality Diagnostic Questionnaire-4 (PDQ-4), Temperament and Character Inventory (TCI), Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire (TEMPS-A), Affective and Emotional Composite Temperament Scale (AFECTS), and Positive Affect and Negative Affect Model (PANAS) was used to data collection. A somatization factor plus temperament and maladaptive spectra of personality were extracted using exploratory factor analysis. Several hierarchical linear and logistic regressions were used to test the predictive systems and spectra., Results: All personality systems jointly predict both somatization and SSRD with a slightly higher contribution for temperament systems. When the temperament and maladaptive spectra were compared, both spectra above each other significantly predicted both somatization (R 2  = .407 versus .263) and SSRD (R 2  = .280 versus .211). The temperament spectrum explained more variance beyond the maladaptive spectrum when predicting both the somatization factor (change in R 2  = .156 versus .012) and SSRD (change in R 2  = .079 versus .010)., Conclusion: All temperament and maladaptive frameworks of personality are complementary to predicting both somatization and SSRD. However, the somatization is more related to the temperament than the maladaptive spectrum of personality., (© 2023. The Author(s).)

Background: Fibrodysplasia ossificans progressiva (FOP) as a rare and heritable disorder with the infrequent genetic transmission of the condition is a catastrophic disorder of heterotopic ossification (HO) and a cause of extraskeletal bone formation in humans. Given the lack of effective treatment for this disease, the important point is to avoid aggravating factors such as bone biopsy, surgery, and intramuscular injection., Case Presentation: In this report, we present a 52-year-old female patient, Kurdish ethnic, suspected to FOP who had a surgical intervention on the second toe of the right foot, which subsequently, it caused further deterioration of the disease in the person including necrosis and amputation of the distal phalanx of the second toe., Conclusions: Although, based on our investigation and the available scientific evidence, surgery may a cause for faster progression and worsening of the FOP disorder, but its proof requires further studies., (© 2023.

Electroconvulsive therapy (ECT) is an effective and safe medical treatment for patients with severe mood and neuropsychiatric disorders. Since the advent of ECT, extensive research has been performed to identify the predictive factors for response to ECT. In recent decades, postictal suppression on an electroencephalogram (EEG) has been considered a potential predictor of response to ECT. We aimed to investigate the direct association between postictal suppression and the therapeutic effects of ECT. In this systematic review, all articles in the field of the association between postictal suppression and the therapeutic effects of ECT published between 1990 and 2021 were identified. The full texts of these articles, which include clinical trials and retrospective and cross-sectional studies, are available in scholarly research databases and search engines, including PubMed, Google Scholar, OVID, Web of Science, and Scopus. Of all retrieved articles, eight studies, including four retrospective cohort articles and four clinical trials, met the inclusion criteria for further analyses. The findings of this study showed a significant association between postictal suppression and the therapeutic efficacy of ECT. Factors such as electrode placement, tachycardia, type of anesthetic agent, and EEG amplitude were also directly related to postictal suppression and the efficacy of ECT. Postictal suppression on EEG can be considered a predictor of response to ECT. To increase the effectiveness of treatment with ECT and increase postictal suppression, factors including electrode placement, tachycardia, type of anesthesia, and EEG amplitude should be considered, which highlights the need for further research., (© 2023 John Wiley & Sons Australia, Ltd.)

In developing countries, broiler farmers often use imbalanced energy diets, hence our study aims to evaluate the combined effect of addition of commercial exogenous enzymes (CEE), in low energy level corn/soybean meal based-diet on performance, serum biochemical parameters, meat characteristics in male and female of broiler chickens. A total of 120 one day old Hubbard F15 broiler chickens were divided on 2 groups (60 animals/group) with 5 replicates/group. The control group received a standard diet, while CEE group received the same diet supplemented with enzymes (250 g/ton). Addition of enzymes reduced significantly feed (p

Surface plasmon technology is regarded as having significant potential for the enhancement of the performance of 2D oxide semiconductors, especially in terms of improving the light absorption of 2D MoO 3 photodetectors. An ultrathin MoO 3 /Ir/SiO 2 /Si heterojunction Schottky self-powered photodetector is introduced here to showcase positive photoconductivity. In wafer-scale production, the initial un-annealed Mo/2 nm Ir/SiO 2 /Si sample displays a sheet carrier concentration of 5.76 × 10 11 /cm², which subsequently increases to 6.74 × 10 12 /cm² after annealing treatment, showing a negative photoconductivity behavior at a 0 V bias voltage. This suggests that annealing enhances the diffusion of Ir into the MoO 3 layer, resulting in an increased phonon scattering probability and, consequently, an extension of the negative photoconductivity behavior. This underscores the significance of negative photoconductive devices in the realm of optoelectronic applications.
