The vague language use scale: Clinical utility and psychometrics from adults with traumatic brain injury.

Pragmatic communication difficulties encompass many distinct behaviours, including the use of vague and/or insufficient language, a common characteristic following traumatic brain injury (TBI) that negatively impacts psychosocial outcomes. Existing assessments evaluate pragmatic communication broadly, often with only one or two items capturing each behaviour, thus limiting sensitivity and precision to variations within each behaviour. Given that greater nuance is needed to detect subtle pragmatic communication differences and investigate underlying cognitive mechanisms, a more refined measure is critical to improve psychosocial outcomes. The Vague scale was developed to address those needs. To provide preliminary evidence supporting the novel Vague language use (Vague) scale's reliability, validity and clinical utility. The Vague scale rates each discourse sample utterance for vague language use on a 3-point scale; the measure's Vague score represents the mean of utterance-level ratings. Using the Vague scale, two raters naïve to diagnosis evaluated Cinderella narratives of 46 adults with severe TBI and 46 controls with no brain injury, providing reliability, construct validity and classification accuracy evidence. Vague scores were also compared to other clinical measures to gather criterion-related validity evidence. Interrater agreement across all transcripts was moderate. Construct validity was supported by expected group differences and criterion validation, including significant relationships with increased violations of Grice's maxim of quantity and measures of lexical variation; significant relationships with psychosocial outcomes, supporting clinical utility; and nonsignificant relationships with measures of syntax and overall pragmatic communication. Classification accuracy expectedly did not support using Vague scores in isolation for diagnosis, due to unacceptable sensitivity (0.696). Evidence supported the Vague scores' psychometric properties. Thus, the Vague scale shows promise as a measure of one distinct pragmatic communication behaviour: vague language use. Future research should apply the Vague scale to determine its sensitivity in individuals with subtle social communication challenges (e.g., mild TBI), explore its utility with more naturalistic discourse samples as part of a pragmatic communication battery, longitudinally examine changes in Vague scores, and investigate cognitive mechanisms underlying this specific pragmatic communication behaviour. What is already known on this subject Use of vague language is common following traumatic brain injury (TBI) and may contribute to negative psychosocial outcomes related to employment and relationships. However, existing measures of vague language lack sensitivity and precision, limiting their utility for identifying subtle performance variations or determining the cognitive mechanisms underlying this specific pragmatic communication behaviour. What this study adds to existing knowledge The current study gathered promising reliability, validity and clinical utility evidence to support using the novel Vague language use (Vague) scale, which was developed to address these limitations. Based on complex (Cinderella) stories of adults with and without TBI, Vague scores demonstrated moderate interrater agreement and promising construct validity based on expected group differences and criterion validation, including moderate associations with related constructs and weak associations with unrelated constructs. Because pragmatic communication profiles post-TBI can vary, classification accuracy expectedly indicated that Vague scores should not be used alone to identify communication differences post-TBI. What are the clinical implications of this work? Vague scores show promise for documenting clients' use of vague language and planning intervention to address associated discourse-level challenges. Future research should investigate applying the Vague scale to naturalistic discourse samples (1) as part of a battery that sensitively and precisely identifies pragmatic communication differences and (2) as a tool for investigating cognitive mechanisms underlying vague language use, with the goal of improving interventions that support pragmatic communication and enhance psychosocial outcomes.

Third generation sequencing analysis detects significant differences in duodenal microbiome composition between functional dyspepsia patients and control subjects.

Functional dyspepsia (FD) is a multifactorial disorder as its development may be based on several different pathophysiological mechanisms. Interaction of gut microbiome with the host has been proposed as a potential mechanism involved in the disease's pathogenesis. We aimed to characterize microbiome profiling on duodenal luminal content (DLC) of FD patients and compare it to that of controls (CG) and patients with irritable bowel syndrome (IBS). Outpatients fulfilling Rome IV criteria for FD, IBS, and control group (CG) underwent upper gastrointestinal endoscopy and 2 cc of duodenal aspirate (3rd - 4th part) was aspirated in sterile traps. Duodenal microbiome was assessed after DNA extraction and 16S gene-based sequencing on Oxford Nanopore MinION followed by EPI2ME analysis (ONT/Metrich-ore Ltd). Bioanalysis of the microbiome (alpha-, beta-diversity, comparisons of relative abundances for all taxonomic ranks) was implemented in Python. Multiple group means comparisons were performed with one-way Analysis of Variance (ANOVA) and Kruskal-Wallis test with Tuckey's and Dunn's post hoc tests respectively, in case of significance (P-value <0.05). 20 subjects with FD (8 females; age 49.9 ± 13.5 yrs.), 20 with IBS (14 females; age 57.6 ± 14.8 yrs.) and 10 CG (6 females; age 49.2 ± 13.8 yrs.) had their DLC analyzed. The α-diversity index of subjects with FD was significantly lower compared to controls (Shannon's index, p = 0.0218) and similar to that of patients with IBS. Principal Coordinate Analysis (PCoA) generated from species relative abundances (beta-diversity) showed no difference in the DLC profile of subjects with FD and IBS when compared to controls (p = 0.513). Compared to controls, the relative abundance (RA) of Chloroflexota phylum was lower in subjects with FD (p = 0.017) and IBS (p = 0.026), respectively. Additionally, the RA of the Rhodothermota and Thermotogota phyla was lower in FD (p = 0.017 and p = 0.018, respectively) but not in IBS patients (p = 0.15 and p = 0.06, respectively) compared to controls. Interestingly, the RA of specific taxa from Chloroflexota, Rhodothermota and Thermotogota phyla were consistently lower in subjects with FD when compared to CG but similar to IBS, during analysis of all the subsequent major ranks of taxonomy. At the class level, there were significant differences in Syntrophobacteria, Acidithiobacillia, Cytophagia and Flavobacteriia between the FD and CG groups (p < 0.05), but no such difference between FD and IBS was found. Finally, multiple significant differences at the order, family, genus and species level between the FD and CG groups were also detected. A positive relationship between the RA of Streptococcus and those from genus Granulicatella was observed both in FD (p = 0.014) and IBS (p = 0.014) patients. The microbiome profiling from duodenal luminal content of FD patients is significantly different to that of controls, including lower microflora diversity, different microflora structure/composition and specific taxa. Similar differences in the DLC between FD and IBS patients were not evident.

The Impact of Empathic Marketing on movie Promotion: A Case Study of the Movie Barbie

In movie marketing, the establishment of emotional empathy has always been the key to success. This study explores the concept of empathy marketing and its application in movie marketing, focusing on how Barbie successfully attracts audiences through empathy marketing strategies. Through the case study of the movie Barbie, this study firstly analyzes how empathy marketing stimulates the audience’s interest and clarifies the target audience of Barbie through STP analysis (market segmentation, target market selection, and market positioning). Secondly, this study proposes specific suggestions for applying empathy marketing in the production and promotion stages of the movie. The study shows that empathy marketing can effectively enhance a movie’s marketing effect by capturing the audience’s psychological needs and emotional resonance, expanding the movie’s scope, enhancing word-of-mouth communication, and thus promoting the movie’s successful release. Future research can further explore the specific mechanisms and necessary conditions of empathy marketing and the systematic categorization criteria of the target groups of movie empathy marketing.

The social ledger: qualitatively decoding interaction-driven investment decisions among Indian investors and fund managers

Purpose This study aims to investigate the antecedents of social interaction among Indian retail investors and fund managers to understand how these factors influence investment decisions. By identifying and examining these antecedents, the study aims to shed light on the social dynamics that shape investment behavior in the Indian financial market. Design/methodology/approach The researchers have mainly adopted an interpretive strategy for the present study. Qualitative data elicited through semistructured interviews with six retail investors and two fund managers were subjected to qualitative thematic analysis. Findings Our research found several factors that make Indian retail investors and fund managers connect and make financial decisions. Peers can improve a person’s investing performance through social facilitation, and discussing investment suggestions and lessons learned can affect a group’s investment behavior. Social norms also influenced investors’ financial decisions, demonstrating compliance. Investor closeness increased information sharing. Finally, the fear of missing out (FOMO), a psychological phenomenon where people fear missing out on rewarding experiences, encouraged social engagement as investors sought appealing prospects. Research limitations/implications The researchers interviewed eight carefully selected interviewees across the divide between retail investors and fund managers. Adopting other grouping criteria, conducting a focus group discussion with more respondents or adopting a mixed-methods approach may increase our understanding of the investment decision behaviors of Indian retail investors and fund managers. Practical implications The findings have far-reaching consequences, from deepening our knowledge of investors’ motivations and actions to directing individual savers, informing the development of financial literacy initiatives, influencing fund management practices and inspiring additional research in this study area. Originality/value This research, including retail investors and fund managers, significantly contributes to the literature on investment decisions and behavioral finance, particularly in the context of Indian investors and managers. This study’s unique perspective and comprehensive approach make it a valuable addition to the field, sparking interest and further exploration among academics, practitioners and investors alike.

Reverse-transcriptase real-time PCR in the diagnostic strategy for invasive infections caused by Aspergillus fumigatus.

The aim was to develop an RT-qPCR targeting Aspergillus fumigatus and compare its performance to that of Aspergillus fumigatus qPCR for the diagnosis of invasive aspergillosis (IA). Samples from patients of the Lyon University hospitals for whom a suspicion of IA led to the realization of an Aspergillus fumigatus qPCR molecular diagnostic test over a 2-year period were included. The patients were classified according to the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC-MSGERC) criteria for suspected IA; RT-qPCR and qPCR assays were performed on all included samples. The sensitivities and specificities of RT-qPCR and qPCR were calculated and compared using the results of the EORTC-MSGERC classification as reference. The cycle threshold (Ct) results were compared according to IA classification and sample type. Among the 193 samples analyzed, 91 were classified as IA excluded, 46 as possible IA, 53 as probable IA, and 3 as proven IA. For all sample types, RT-qPCR was significantly more sensitive than qPCR for all IA classifications with an additional 17/102 samples detected (P-value < 0.01). For plasma samples, sensitivity was significantly higher and specificity significantly lower using RT-qPCR for all IA classifications (P-value < 0.001). The mean Ct obtained with RT-qPCR were significantly lower than those obtained with qPCR for all IA classifications and all sample types (P-value < 0.001 and P-value < 0.0001, respectively). RT-qPCR presents a higher sensitivity than qPCR for the diagnosis of IA due to Aspergillus fumigatus, particularly in samples with an intrinsically low fungal load.IMPORTANCEAspergillus fumigatus belongs to the critical priority group of the World Health Organization fungal priority pathogens list. Invasive aspergillosis (IA) is a life-threatening infection with poor prognosis and challenging diagnosis. PCR has been integrated into the 2020 European Organization for Research and Treatment of Cancer/Mycoses Study Group consensus definitions for IA diagnosis. However, due to frequent low fungal burdens, its sensitivity needs to be improved. This work presents an innovative method for detecting total nucleic acids, corresponding to both ribosomal RNA and DNA, that enables IA diagnosis with greater sensitivity than conventional techniques, especially in non-invasive samples such as blood, enhancing the monitoring of this infection in high-risk patients.

Aspergillus serology and clinical outcomes in patients with bronchiectasis: data from the European Bronchiectasis Registry (EMBARC)

IntroductionAspergillus sp. cause diverse clinical manifestations in bronchiectasis including Allergic bronchopulmonary aspergillosis (ABPA), Aspergillus sensitization (AS) and raised IgG indicating exposure or infection with Aspergillus. Research QuestionWhat is the prevalence and clinical significance of Aspergillus-associated conditions in individuals with bronchiectasis? MethodsBronchiectasis patients enrolled into the EMBARC registry from 2015 to 2022 with laboratory testing for Aspergillus lung disease (total IgE, specific IgE to Aspergillus or Aspergillus skin test, IgG to Aspergillus and blood eosinophil counts) were included for analysis. Modified-ISHAM-ABPA working group criteria (2021) were used to define ABPA. Results9953 patients were included. 608 (6.1%) were classified as having ABPA, 570 (5.7%) showed Aspergillus sensitization, 806 (8.1%) had raised Aspergillus-specific IgG without sensitisation, 184 (1.8%) were both sensitised to Aspergillus and had raised Aspergillus-specific IgG and 619 (6.2%) had eosinophilic bronchiectasis (elevated eosinophil counts without evidence of Aspergillus lung disease). The remaining 72.0% had negative Aspergillus serology. Patients with ABPA, Aspergillus sensitization, and raised Aspergillus-specific IgG had more severe disease, with worse lung function and more frequent exacerbations at baseline. During long-term follow-up, patients with raised Aspergillus-specific IgG had higher exacerbation frequency and more severe exacerbations. Aspergillus sensitization associated with increased exacerbations and hospitalisations only in patients not receiving inhaled corticosteroids. InterpretationAspergillus lung disease is common in bronchiectasis. Raised IgG to Aspergillus is associated with significantly worse outcomes while ABPA and Aspergillus sensitization are associated with severe disease and exacerbations with a risk that is attenuated by inhaled corticosteroid use.

The presence of oligoclonal bands predicts conversion to multiple sclerosis in isolated myelitis

Acute transverse myelitis (ATM) is a disease characterized by inflammation of the spinal cord and may have various causes. In the context of this work, the distinction between isolated ATM and initial manifestation of autoimmune-mediated diseases of the central nervous system such as multiple sclerosis (MS) is crucial. Hence, the aim of this work was to identify predictive factors associated with the conversion to definite MS in a collective of individuals after their initial episode of isolated ATM (no initial identified cause). In this retrospective data analysis from the Vienna MS Database, all patients from Jan. 1, 1999, to Dec. 31, 2019, with a diagnosis of isolated ATM (according to the criteria of the Transverse Myelitis Consortium Working Group) who underwent lumbar puncture were extracted. Electronic medical records were reviewed on the availability of clinical data including therapy and follow-up, laboratory results including cerebrospinal fluid (CSF) analysis, evoked potentials (EP) as well as magnetic resonance imaging data. Among 42 patients with the diagnosis of isolated ATM, 12 (29%) were subsequently diagnosed with MS over a median follow-up period of 7.7 years. Univariately, MS converters were younger (32 years [25–39] vs. 42 years [31–50], p = 0.032), had a lower CSF/serum albumin ratio (29 [24–35] vs 37 [27–52], p = 0.037), lower CSF total protein (4.5 [2.8–4.8] vs. 5.5 [3.4–8.5], p = 0.023) and a higher proportion of CSF-specific oligoclonal bands (OCB; 83% vs. 30%, p = 0.002). In the multivariate regression analysis, the presence of CSF-specific OCB emerged as the sole predictive factor of subsequent MS diagnosis (OR: 14.42, 95% CI 1.39 to 149.48, p = 0.03). In a collective of 42 patients with isolated ATM and an MS conversion rate of nearly 30%, the only but highly predictive factor were CSF-specific OCB. This emphasizes the significance of conducting timely CSF analysis in such patients and underscores the need for tailored monitoring and follow-up strategies in this specific group.

A 7-year-boy with Recurrent Acute Disseminated Encephalomyelitis: A Case Report

Acute Disseminated Encephalomyelitis (ADEM) is one form of inflammatory demyelinating disorder of central nervous system affecting the children following an idiopathic course of onset and usually monophasic. Recurrent ADEM is a rare entity and will arise a confusion about its diagnosis. There is no definite clinical criteria and treatment protocol for the management of ADEM. Here we report a case of recurrent ADEM where a 6 year old boy presented with recurrent episodes of low grade fever, difficulty in walking, altered sensorium and focal seizure. MRI of brain showed reappearance of demyelinating lesion on the previous site. The gap between first and second episode was six months. After the first attack of ADEM patient were completely recovered both clinically and neuroradiologically with immunotherapy. But after 7 months of disease free remission, patient again developed same features. So we diagnosed the baby as recurrent ADEM based on the consensus criteria of International Pediatric MS study group (IPMSSG). BANGLADESH J CHILD HEALTH 2023; VOL 47 (1) : 51-54

Characteristics of patients with liver tumors deemed ineligible for enrollment on Children's Oncology Group trial AHEP1531: An opportunity to expand inclusion criteria and improve outcome.

Specific patients with hepatoblastoma (HB) and hepatocellular carcinoma (HCC) do not meet eligibility criteria for Children's Oncology Group (COG) trials, limiting an understanding of how comorbidities affect the outcome. We define such a population for future-focused care improvements. A questionnaire was sent to COG institutional principal investigators to obtain anonymized data regarding patients with a liver tumor diagnosis not enrolled on AHEP1531 due to ineligibility by trial criteria or other reasons (excluding parent/patient preference). Responses received for 55 patients (38 HB, 4 HCC, and 13 not reported) included 12 excluded from further analysis due to various factors, including lack of additional information. Five patients were eligible but not enrolled due to pandemic-related staffing issues (n=1) or the best interest of the patient (physician preference, n=1; risk for poor tolerance of chemotherapy, n=1; not specified, n=2). The remaining 38 patients included 1 ineligible due to a prior malignancy, 9 due to performance status, and 4 due to timing requirements. Thirty-five of 38 patients were ineligible due to organ function criteria (pulmonary/oxygen requirement, n=25; renal, n=10; liver, n=4; cardiac, n=3). Seven patients were ineligible due to two or more organ function criteria. Twenty-five of 38 patients were reported to have a preexisting condition including 4 patients with trisomy 18. Patients with HB, and potentially HCC, who are ineligible for COG trials are primarily patients with an oxygen requirement and/or renal insufficiency, often associated with preexisting congenital conditions. Such patients would benefit from future studies to improve outcomes.

STUDY OF THE ENDOMETRIAL GLANDULAR COMPONENT IN WOMEN WITH FERTILITY AND POST-COVID SYNDROME IN ANAMNESIS

The aim. To increase the effectiveness of the endometrial endometrial glandular component study in women with infertility and post-COVID syndrome. Materials and methods. A study was conducted at the State institution "Carpathian Human Reproduction Centre" of the Ministry of Health of Ukraine in the period from 2022 to the end of the first half-year of 2024. There were included 80 women in the experimental group and 40 women in the control group. The selection criterion for the study group was the presence of documented post-COVID syndrome (COVID-19 symptoms lasted longer than 12 weeks). The selection criterion for the control group was the absence of confirmed SARS-CoV-2 virus in the anamnesis. The following characteristics were common for both groups: diagnosed infertility, age – 25-42 years, written informed consent of the patient to participate in the study. The criteria for exclusion from the study for patients of both groups were: detection of human immunodeficiency virus, viral hepatitis, other sexually transmitted infections, tuberculosis of the genitourinary system, malignant diseases, mental disorders that make communication with person impossible or the awareness of written consent is questioned. General clinical and laboratory examinations and transvaginal sonographic examination of the pelvic organs were performed in the middle stage of proliferation and the middle stage of secretion according to the calendar calculation the menstrual cycle. A visually guided diagnostic office hysteroscopy was performed with the collection of biological material from the most changed areas (biopsies were collected in the middle stage of proliferation and the middle stage of secretion in different menstrual cycles). A routine staining of samples with hematoxylin-eosin, morphometry of the endometrial glandular component, optical determination of the number of glands and measurement of the diameter of the lumen of the studied glands, considering the possible measurement error, glandular-stromal ratio, functional activity of the glands, were performed. A histochemical PAS-reaction to identify the glycoproteins of gland secretions and immunohistochemical staining of the glandular epithelium to express the receptivity of the glands to estrogen and progesterone were carried out. The results. After conducting the PAS-reaction, a higher secretion was noted in the glands than in the stroma of the endometrium during the period of the implantation window in both cohorts. No statistically significant difference between the groups in the amount of glycogen of the middle proliferative phase in the glands (p=0.315) or stroma (p=0.486). Glycogen in this phase was visualized of very small granules and coarse granules, without their formation in clusters. A decrease in secretion was established in 16 (40%) patients of the control group and 49 (61.3%) women of the experimental group in the middle secretory phase, which was statistically significant (p=0.028). A decrease in the expression level of the progesterone receptor in the middle secretory phase was found to be significantly more pronounced in the experimental group than in the control group (р=0.044). Conclusions. In the middle secretory phase, a decrease in the secretion of glycogen by the endometrial glands and a decrease in the level of expression of the progesterone receptor in endometrial biopsies were detected by the routine histological, histochemical techniques and immunohistochemical stude in women with infertility and a history of post-COVID syndrome.

CHARACTERISTICS OF THE HOSPITALIZATION PERIOD IN PATIENTS WHO DIED AS A RESULT OF COVID-19 WITH ACUTE CARDIOVASCULAR COMPLICATIONS

The aim. To identify adverse risk factors in hospitalized patients with fatal consequences of the coronavirus disease-2019 and its acute cardiovascular complications. Materials and methods. A retrospective study was conducted of 66 people in the study group with acute respiratory failure and cardiovascular complications due to COVID-19. The comparison group was 48 people who died of acute cardiovascular events without SARS-CoV-2 infection or other bacterial or viral diseases. The criteria for inclusion in the study group were the presence of confirmed SARS-CoV-2 infection by the polymerase chain reaction method, the presence of acute cardiovascular complications during COVID-19, and patients hospitalized during its treatment. Inclusion criteria for the comparison group were hospitalized patients with acute cardiovascular diseases that led to death without SARS-CoV-2 infection. The exclusion criteria for both groups were: age before 18 years old; absence of informed consent of the authorized person of dead person or the decision of the authorized person to withdraw from the study at any of the stages; the presence of other co-infections that could have a cumulative negative effect on the state of the respiratory and cardiovascular systems (flu virus, hepatitis virus, human immunodeficiency virus, pathogens that led to symptoms of acute intestinal infections). Age and gender distribution, comorbidities, length of hospitalization, and laboratory markers were evaluated in both cohorts. Cardiovascular complications were confirmed by the results of ultrasound examinations, computed tomography angiography and comparison with postmortem morphological findings in autopsy reports for the analysis of the current study,. The results. There were 48 men (72.7%) and 18 women (27.3%) in the study group of 66 patients who developed cardiovascular complications at the background of COVID-19, and in the comparison group – 39 men (81.3%) and 9 women (18.7%), which indicates acceptable comparability of the groups among themselves due to sex (p=0.374) and age (p=0.338). In particular, the age median for men in the study group was 65 years (IQR - 21 years), with minimum and maximum age values ​​– 36 and 83 years, respectively; the median age for women in the study group was also 65 years (IQR – 12.5 years), with the lower and upper age limits in the group being 41 and 78 years. The age median for men in the comparison group was 62 years (IQR 15 years), with a lower and upper age range of 54 and 81 years. The age median for women in the comparison group was 68 years (IQR – 16.5 years), with the lower and upper age values ​​in the group being 55 and 79 years. Men and women of the comparison group did not statistically differ from each other in terms of age (р=0.412). A significant difference was found between the length of hospitalization in both cohorts (р˂0.00001) – the median length of stay in hospital for the study group was 15 days, and for the comparison group – 10 days. It was established that malignant diseases were an additional concomitant factor of mortality in the group of patients with COVID-19 (р=0.043). The percentage ratio of neutrophils (p=0.048) and lymphocytes (p=0.031) in patients of the study group significantly differed. Conclusions. Unfavorable risk factors in patients with fatal consequences of Coronavirus disease-2019 and acute cardiovascular complications were concomitant oncological pathology, a long period of hospitalization, and changes in the percentage ratio of neutrophils and lymphocytes.

Is HLA-DQ typing useful in screening for celiac disease among Arabs with type 1 diabetes? A case-control study.

The data on the usefulness of DQ-typing in screening for celiac disease (CD) among type 1 diabetic (T1D) patients came from the West. We conducted this study among T1D patients to: (1) determine the frequency of DQ-genotypes, (2) assess the risk associated with human leukocyte antigen (HLA)-DQ genotypes, and (3) identify the cost-effective screening strategy. HLA-DQ genotyping was performed on 67 T1D patients with CD (cases) (mean age 15 years) and 224 T1D patients without CD (controls) (mean age 18.29 years) (2021-2023). The entry criterion for the control group was duration of T1D ≥5 years and negative annual celiac serology assay. On comparison of the cases versus controls, T1D patients carrying homozygous DQ2.5 genotype (30% vs. 13.8%) or DR3-DQ2.5 haplotype (81.3% vs. 65.7%) showed significantly "higher risk" (odds ratio [OR] = 2.64, p = 0.002; OR = 2.3, p = 0.008, respectively) to develop CD. Only 4% do not harbor any of the CD-at risk genotypes (DQ2.5, DQ8, or DQ2.2) and none developed CD. Heterozygous DQ8 was associated with a significantly lower risk of developing CD with OR of 0.123 (1.5% in cases vs. 10.3% in controls, p = 0.022). Only 4% of Saudi patients with T1D carry DQ-genotypes at no risk to develop CD, which supports the European guidelines that recommend celiac serology test as the most cost-effective screening method. We identified the risk gradient associated with DQ-genotypes to develop CD in our population which could help in counseling patients for the risk to develop CD and planning follow-up serology tests.

Prevalence of Internet Use among Adolescents of 15 to 18 Years of Age in A Village under RHTC of A Medical College: Cross-Sectional Study

Background: The environment in which today’s adolescents are growing has changed drastically and affected their access to internet as well. The study was conducted with the aim of estimating the prevalence of internet use and pattern of internet use among adolescents of a village area. Methods: About 114 adolescents of a village in Western Maharashtra belonging to age group 15-18 years participated in the study. They were selected based on the inclusion criteria of age group and willingness to participate in the study via universal sampling method and were interviewed with the help of semi-structured questionnaire, which included questions regarding socio-demography, internet use and its interrelationship with other variables. Chi-square test was used as a test of statistical significance to study the association between the predictor variable and the outcome with (p&lt;0.05) as a level of significance. Results: The prevalence of internet use was 99.12%. Where 74% of adolescents used internet for an average of 1-2 hours in a day and 26% used internet for an about 2-4 hours in a day. Taking p &lt; 0.05 as a level of significance we found gender was significantly associated with duration of internet use (p = 0.01) and Purpose of internet use (p = 0.004). Conclusion: Almost all adolescents have access to internet and are more inclined towards its use for non-educational purpose which can be detrimental for their educational progress and long-term career goals. Hence, monitoring of internet use by adolescents has to be done by guardians/teachers. Further studies should be conducted on cause-effect relationship to study the either way of association.

Vestibular Dysfunction in Euthyroid Children with Hashimoto's Thyroiditis.

A relationship exists between autoimmune thyroid disorders and vestibular dysfunction. This study aimed to analyze cervicalevoked myogenic potentials (cVEMP) and video head impulse test (vHIT) results between children with Hashimoto thyroiditis (HT) and healthy controls to determine vestibular end-organ problems. Thirty-six children with HT and 30 healthy subjects were recruited. The main inclusion criteria for the healthy group were the presence of normal thyroid function and no clinical history of vestibular problems. Each participant (both HT and healthy groups) was assessed using audiovestibular tests, cVEMP, and vHIT. There was no significant difference between the groups in terms of cVEMP (p1 and n1) latencies for both ears. There was no significant difference in cVEMP amplitudes (p1-n1 peak-to-peak) between the groups. There were statistically significant differences in the VOR gain of the right and left ears between the groups (P < .001, P < .001). When we considered lower cutoff value as 0.80 for VOR gain, 29 of 36 patients with HT (80.6%) had lower VOR gain scores. Only 1 of 30 healthy participants (3.3%) had a lower VOR gain score. This difference was statistically significant (P < .001). Subclinical vestibulopathy may occur in children with HT. The vHIT seems to be a valuable tool for identifying and screening preclinical vestibular pathologies in this patient group.

Study on serum vitamin A level in patients with type 1 diabetes: A systematic review and meta-analysis.

There is controversy about the relationship between type 1 diabetes and vitamin A (VA) levels in the body. Through meta-analysis, the results of related studies can be aggregated to more accurately estimate the relationship between type 1 diabetes mellitus (T1DM) patients and the level of VA in the body. Our purpose is to review the study to investigate VA levels in type T1DM patients and to provide recommendations for future studies. Until January 2024, we searched the National Library of Medicine (PubMed), Cochrane Library, Embase Databases, Web of Sciences, Scopus, China National Knowledge Infrastructure (CNKI), VIP databases (VIP) and WAN FANG databases. After a systematic search, 8 case-control studies were included in our meta-analysis. In the process of data inclusion and extraction, the 2 reviewers selected literature independently of each other. In this study, RevMan5.3 software was used for meta-analysis. Eight case-control studies involving 689 participants were screened. The results after meta-analysis showed that there was a significant difference in serum VA between the patients with T1DM and the control group (standardized mean difference [SMD] = -0.82, 95% CI [-1.29, -0.36], P < .001, random effects model) with significant heterogeneity among these studies (P < .001, I2 = 84%). Similarly, the difference in the high-performance liquid chromatography (HPLC) subgroup on serum VA (SMD = -0.99, 95% CI [-1.60, -0.38], P = .002) as well as the difference in the countries of Asia and Europe subgroup on serum VA (SMD = -0.60, 95% CI [-1.15, -0.05], P = .03; SMD = -1.06, 95% CI [-1.88, -0.24], P = .01) were suggested to be statistically significant. A significant result was also observed in the National Diabetes Data Group (NDDG) criteria subgroup (SMD = -0.48, 95% CI [-0.85, -0.12]). Serum VA levels seem to have decreased in T1DM patients. Further research is needed to strengthen this finding and clarify possible impact mechanisms.

Is early pregnancy hemoglobin A1c useful to predict gestational diabetes mellitus diagnosed during mid pregnancy?

To verify whether hemoglobin A1c (HbA1c) levels in early pregnancy can predict the diagnosis of gestational diabetes mellitus (GDM) in mid-pregnancy. This was a retrospective cohort study of 2008 pregnant women who delivered singletons at the Yokohama City university Medical Center. Concomitant or history of diabetes mellitus and overt diabetes in pregnancy were excluded. Pregnant women at high risk for GDM underwent a one-step 75-g oral glucose tolerance test (OGTT) during mid-pregnancy. For other pregnant women, GDM was diagnosed by a two-step 75-g oral glucose tolerance test (OGTT) when the 50-g glucose challenge test result in mid-pregnancy was ≥140 mg/dL. The thresholds for 75-g OGTT followed those of the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria (92-180-153 mg/dL). The relationship between HbA1c level measured at <20 weeks of gestation and GDM diagnosis at mid pregnancy was assessed using a receiver operating characteristic curve (ROC); area under the curve (AUC) and optimal cutoff value of HbA1c, predictive of GDM were calculated. The median HbA1c level at <20 weeks of gestation was 5.3%, and 8.5% of women were diagnosed with GDM. In the ROC curve of the GDM diagnosis rate by HbA1c level, AUC was 0.706, and the optimal cutoff value was 5.4%, with a sensitivity of 0.6176, specificity of 0.6834, positive predictive value of 15.4%, and negative predictive value of 95.1%. Although HbA1c at less than 20 weeks of gestation is acceptable discrimination as a diagnostic tool of GDM in mid-pregnancy, it is not clinically useful to predict GDM in mid-pregnancy.

Automated quality control analysis for American College of Radiology (ACR) digital mammography (DM) phantom images.

To develop and validate an automated software analysis method for mammography image quality assessment of the American College of Radiology (ACR) digital mammography (DM) phantom images. Twenty-seven DICOM images were acquired using Fuji mammography systems. All images were evaluated by three expert medical physicists using the Royal Australian and New Zealand College of Radiologists (RANZCR) mammography quality control guideline. To enhance the robustness and sensitivity assessment of our algorithm, an additional set of 12 images from a Hologic mammography system was included to test various phantom positional adjustments. The software automatically chose multiple regions of interest (ROIs) for analysis. A template matching method was primarily used for image analysis, followed by an additional method that locates and scores each target object (speck groups, fibers, and masses). The software performance shows a good to excellent agreement with the average scoring of observers (intraclass correlation coefficient [ICC] of 0.75, 0.79, 0.82 for speck groups, fibers, and masses, respectively). No significant differences were found in the scoring of target objects between human observers and the software. Both methods achieved scores meeting the pass criteria for speck groups and masses. Expert observers allocated lower scores to fiber objects, with diameters less than 0.61mm, when compared to the software. The software was able to accurately score objects when the phantom position changed by up to 25mm laterally, up to 5 degrees rotation, and overhanging the chest wall edge by up to 15mm. Automated software analysis is a feasible method that may help improve the consistency and reproducibility of mammography image quality assessment with reduced reliance on human interaction and processing time.

Application of Fe2O3 nanoparticles improves the growth, antioxidant power, flavonoid content, and essential oil yield and composition of Dracocephalum kotschyi Boiss.

Dracocephalum kotschyi Boiss., an endemic and endangered medicinal and aromatic plant in Iran, showcases distinct botanical characteristics and therapeutic promise. According to the IUCN grouping criteria, this plant is facing challenges due to overcollection from its natural habitats. To address this issue, there is an increasing inclination towards cultivating this species within agricultural systems. This study aimed to evaluate the impact of applying Fe2O3 nanoparticles (NPs) at varying concentrations (50, 100, and 200 mg L-1), as well as bulk Fe2O3 at the same concentrations, on the growth, essential oil production, antioxidant capacity, total phenol, and flavonoid content of D. kotschyi. The foliar application of 100 and/or 200 mg L-1 of Fe2O3 NPs resulted in the greatest leaf length and dry weight, while Fe2O3 NPs at the level of 100 mg L-1 led to the highest leaf/stem ratio. Additionally, spraying 200 mg L-1 of Fe2O3 NPs and all concentrations of bulk Fe2O3 positively impacted chlorophyll and carotenoid levels. Both nano and bulk Fe2O3 supplements stimulated H2O2 production and subsequently enhanced enzymatic antioxidant activity. The use of 50 mg L-1 of Fe2O3 NPs resulted in the highest flavonoid content and non-enzymatic antioxidant activity. Meanwhile, the highest essential oil content and yield was achieved by the application of 50 and/or 100 mg L-1 Fe2O3 NPs. The addition of low concentration of Fe2O3 NPs (50 mg L-1) resulted in a significant increase in the concentration of geranial, while a higher supply of Fe2O3 NPs (200 mg L-1) significantly decreased the percentage of neral in the essential oil. Overall, the application of Fe2O3 NPs demonstrated significant potential for increased biomass, enhanced yield, essential oil production, and phytochemical attributes. The findings highlight the versatility of Fe2O3 NPs at optimal concentrations, acting as both a nano-fertilizer and a nano-inducer, promoting the production and accumulation of valuable secondary metabolites in plants.

Nuclear factor kappa B 1 A > G single-nucleotide polymorphism (rs4648068) in Egyptian patients with Behcet’s syndrome, case–control study

BackgroundBehcet's syndrome (BS) is a variable-vessel vasculitis characterized by hyperactive innate immunity. The nuclear factor kappa B (NFKB) pathway is involved in the regulation of inflammatory responses including innate and adaptive immune responses. BS could be associated with NFKB hyperactivation. We aimed to study the association between the NFKB1 A > G (rs4648068) single-nucleotide polymorphism (SNP) and BS in Egyptian patients, in comparison to healthy controls, and to correlate the presence of rs4648068 SNP with the different activity domains of the disease. After ethical committee approval (Faculty of Medicine, Cairo University, Egypt, code MD-228-2022), the International Study Group Criteria for Behçet's Disease (ISG) criteria was used to recruit 60 BS patients, and the activity of the disease was assessed using Behcet’s Disease Current Activity Form (BDCAF) and the Behcet Syndrome Activity Score (BSAS). Another 60 matched controls were recruited. DNA extraction was done followed by PCR amplification to detect the target SNP.ResultsThe GG genotype was significantly higher in BS versus controls (21.7% and 5%, respectively, p value = 0.015). Also, the G allele was significantly higher in BS versus controls (43.3% and 30%, respectively, p value = 0.033). Of the whole activity domains, only arthralgia was found to be significantly correlated with rs4648068 SNP.ConclusionNFKB1 rs4648068 A > G SNP increases the risk of developing BS. Among patients with BS, the GG genotype is protective against developing arthralgia. There is no statistically significant relation between rs4648068 SNP and either other activity domains of BS or the different activity scores of the disease.

9172 Contrasting Bone Profiles In Pcos Are Related To Bmi: A Systematic Review And Meta-analysis

Abstract Disclosure: M.O. Premaor: None. G. Risseti: None. J. Piovezan: None. F.V. Comim: None. Polycystic ovary syndrome (PCOS) is a complex and multifaceted disorder that may affect bone health. Controversial results have emerged regarding whether PCOS is protective or increases the risk of bone frailty. We conducted a systematic review and meta-analysis of published research on bone mineral density (BMD), bone markers, and the risk of fractures in individuals with PCOS. We searched MEDLINE, Embase, and conference s and preprints. Studies were eligible if the PCOS was defined according to the NIH criteria, the Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus Workshop Group criteria, AE-PCOS society criteria, or ICD codes. The endpoints studied included fractures, bone mineral density (BMD), and bone markers. The study protocol is available at PROSPERO (CRD42016049664). From the 3322 studies identified in the databases, 111 had their full texts evaluated, and 31 studies met the inclusion criteria for qualitative analysis. Overall, cross-sectional studies included 1822 individuals with PCOS and 1374 controls, while cohort studies incorporated 30305 women with PCOS and 101907 controls. No differences were observed between individuals with PCOS and the control group in the pooled analysis for the whole group. Nevertheless, contrasting profiles emerged after stratification using a BMI cutoff of 27 kg/m2. Women with PCOS and a mean BMI &amp;lt;27 kg/m2 exhibited lower spine BMD (MD -0.060; 95% CI, -0.110 and -0.011) and total hip BMD (MD -0.042; 95% CI, -0.068 and -0.017), and increased bone resorption marker (CTX) levels (SMD 0.38; 95%CI 0.03 and 0.72). Conversely, women with PCOS and a mean &amp;gt;27 kg/m2 exhibited increased spine BMD (MD 0.029; CI 95%, 0.009 to 0.048) and total hip BMD (MD 0.036; CI 95%, 0.010 to 0.063), with no significant changes in bone resorption markers. Due to the limited number of longitudinal studies available, it was not possible to determine the risk of bone fractures in both groups. In conclusion, the findings of this systematic review show a negative impact of PCOS on bone health in women with a BMI &amp;lt;27 kg/m2, suggesting that increased surveillance and research for bone disease may be necessary for this particular group.
