Abstract
Background
Previous studies assessing the hypothesis that the construct of ‘aberrant salience’ is associated with psychosis and psychotic symptoms showed conflicting results. For this reason, the association between measures to index aberrant salience and subclinical psychotic symptoms in a general population sample was analysed. In addition, genetic vulnerability was added to the analysis as a modifier to test the hypothesis that modification by genetic vulnerability may explain variability in the results.

Methods
The TwinssCan project obtained data from general population twins (N = 887). CAPE (Community Assessment of Psychic Experience) scores were used to index psychotic experiences. Aberrant salience was assessed with white noise task and ambiguous situations task.

Results
Measures of aberrant salience were not associated with psychotic experiences, nor was there evidence for an interaction with genetic predisposition in this association (Z = 1.08, p = 0.282).

Conclusions
Various studies including the present could not replicate the association between aberrant salience and psychotic experiences in general population samples. The conflicting findings might be explained by moderation by genetic vulnerability, but results are inconsistent. If there was evidence for a main effect or interaction, this was in the positive symptom scale only. On the other hand, the association was more robust in so-called ‘ultra-high risk’ patients and first episode psychosis patients. Thus, this association may represent a state-dependent association, present only at the more severe end of the psychosis spectrum.

Published: October 2024

Abstract
Background
One procedure that has gained popularity in the surgical management of hallux valgus is the minimally invasive Chevron and Akin osteotomy (MICA). The purpose of this systematic review was to evaluate the learning curve associated with this technically demanding procedure.

Methods
A search of the EMBASE and PubMed databases was performed to identify all clinical studies that assessed the learning curve associated with the MICA procedure. Studies where patients were not diagnosed with hallux valgus, did not undergo MICA, or did not report data on operation time, fluoroscopy exposure, or complications were excluded. A risk of bias assessment was conducted to assess the validity of the studies.

Results
The initial literature search yielded 287 studies, and seven studies were included in the final analysis. A quantitative comparative analysis could not be performed as the included studies used different statistical methods to quantify the learning curve. Lewis et al. determined that after 38 operations, there was a decrease in operation time and fluoroscopy exposure (p < .001). Merc et al. found that it took 29 and 30 operations to reach a plateau for operation time and fluoroscopy exposure, respectively (p < .001). Palmanovich et al. found that it took 20 and 26 operations to reach a plateau for operation time and fluoroscopy exposure, respectively (p < .001). Toepfer and Strässle found there was a significant decrease in operation time and fluoroscopy exposure after the first 19 procedures in their series (p < .001). With respect to complications, one study found a significant difference after the 42nd operation (p = .007). However, the remaining studies found that complication rates did not significantly change with increased technical proficiency. All seven studies were deemed to have a moderate risk of bias.

Conclusions
Surgeons can expect a learning curve of 20 to 40 operations before reaching technical proficiency with the MICA procedure. After the learning curve is achieved, surgeons can expect to see a significant decrease in both operation times and fluoroscopy exposure. No consistent significant difference was found in complications as one becomes more technically proficient with the procedure.
Evaluating the effectiveness of web-based oral health education on enhancing mothers’ awareness: a semi-experimental internet-based intervention
Authors: Kashani Kasra , Shahravan Arash , Sarafinejad Afshin 
Published: October 2024

Abstract
Objectives
This study examined the impact of web-based education on enhancing mothers’ awareness of oral health care for children aged 9 and 12 years. It focused on the crucial role of mothers in educating about oral health to prevent dental diseases and reduce long-term healthcare costs.

Methods
Mothers were divided into three groups: control, intervention with a web system, and intervention with a brochure. Over one month, their knowledge about their children’s oral health was assessed before and after the intervention.

Results
Data were analyzed using parametric t-tests and non-parametric Mann-Whitney U tests. The findings indicated a significant increase in parental awareness in both intervention groups.

Conclusion
It is recommended that parent education be done using web-based systems or mobile apps, which are better choices due to greater accessibility and interactivity.

Published: October 2024

Abstract
Background
Central odontogenic fibroma (COF) is a rare benign odontogenic tumor with a wide range of histopathologic features. We evaluated COF diagnosed in our institute with 16 years’ experience using 2022 WHO classification.

Methods
Our archives were reviewed and cases diagnosed as COF were selected. Clinical, radiographic and microscopic features were tabulated and analyzed.

Results
Of 13,736 specimens, six cases (0.04%) of COF were discovered. Patients ranged in age from 14 to 44 years. There were two males and four females. Maxilla and mandible were affected equally. Five cases showed radiolucent appearance (4 unilocular, 1 multilocular) and one case showed a mixed radiolucent-radiopaque pattern. Histopathologically, three cases were conventional type (2 epithelium-rich, 1 epithelium-poor). Two cases were the hybrid COF with central giant cell granuloma (CGCG) and one of which was also associated with secondary aneurysmal bone cyst (ABC). The last case with a mixed radiolucent-radiopaque pattern was the ossifying subtype.

Conclusion
Our results demonstrated that COF is a rare odontogenic tumor and exhibits diverse radiographic and microscopic appearances. The triphasic tumor consisting of the COF, CGCG and ABC, is reported here for the first time, while the ossifying subtype is considered the tenth case reported in the English-language literature. Oral and maxillofacial pathologists and other healthcare personnel must be aware of this rare odontogenic tumor and its variants to achieve the definite diagnosis.

Published: October 2024

Abstract
Background
India bears the highest global burden of oral cancer, despite having an operational tobacco cessation framework. Occupational groups like solid waste management personnel face significant health challenges due to prevalent tobacco use, leading to oral potentially malignant lesions and oral cancer. Enhanced tobacco control strategies are essential for these groups.

Methods
A pre-post interventional, community-based study enrolled 1200 municipal workers in Varanasi, India, from July 2022 to August 2023. 858 tobacco users underwent screening and were randomly assigned to one of three interventions: Very Brief Advice, Individual Behavioral Counseling, or Group Behavioral Therapy. Follow-up was conducted one year after the baseline interventions Effectiveness was measured by nicotine dependence reduction using the Fagerstrom Test for Nicotine Dependence (FTND) scores and cessation rates defined as at least 6-month abstinence. Appropriate statistical tests assessed the burden of tobacco use, oral potentially malignant lesions, and pre-post differences in FTND scores within and between groups. A p-value of < 0.05 was considered statistically significant.

Results
Municipal workers exhibited a high prevalence (71.5%) of smokeless tobacco (SLT) use. One-third (32.9%) of the participants screened positive for oral potentially malignant lesions and oral cancer. Leukoplakia was the most common lesion. Screened positivity correlated with significant nicotine dependence. Among 494 follow-up participants, 47.1% reported a significant reduction in nicotine dependence across all intervention groups. Quade’s ANCOVA indicated significant differences in post-test FTND scores, with individual behavioral counselling showing the greatest reduction. However, no cessation was achieved in any group despite the significant decline in dependence.

Conclusion
Solid waste management personnel in Varanasi show heightened SLT use and associated oral potentially malignant lesions. The persistent tobacco use in these high-risk occupational populations undermines government tobacco control efforts and highlights the need for robust policy and implementation strategies. The study demonstrated a significant reduction in nicotine dependence following interventions, though tobacco cessation was not achieved. More frequent interventions and addressing quitting barriers—such as cultural norms, lack of awareness, easy accessibility, and adverse working conditions—are crucial. Developing a tailored workplace model to tackle tobacco use in occupational settings may facilitate cessation.

Diagnosis of canine B-cell chronic lymphoid leukemia with a CD21 negative phenotype using the LT21 clone CD21 antibody in flow cytometry: a case report
Authors: Choi Eun Wha , Jeong Yunho , Ahn Jin-Ok 
Published: October 2024

Abstract
Background
Chronic lymphoid leukemia (CLL) is a hematological disorder characterized by the clonal expansion of small mature lymphocytes that accumulate in the blood and bone marrow. CLL can arise from B-, T-, or natural killer cell clones. The cytological evaluation of blood smears is often the simplest and least invasive method for diagnosing lymphoid leukemia. Immunophenotyping is used to further subclassify the type of lymphoid leukemia.

Case presentation
A 15-year-old, 4.4-kg spayed female Shih Tzu was presented to the veterinary medical teaching hospital of Kangwon National University. Despite having a normal appetite and activity level, cervical and inguinal lymph node enlargement was noted on physical examination. Complete blood count revealed severe leukocytosis, severe lymphocytosis, and monocytosis. Splenomegaly, hepatomegaly, and lymph node enlargement were detected on radiographic and ultrasonographic examination. Immunophenotyping was performed using peripheral blood mononuclear cells (PBMCs). The majority of lymphocytes exhibited the following profiles: CD3−CD79a− (97.5%), CD4−CD8− (98.6%), CD21−CD79a− (98.4%), CD34− (0.1%), CD45+ (99.6%), major histocompatibility complex class II+ (99.5%), and CD14− (0.5%). Based on the immunophenotyping results, possible differentials considered included the following: the majority of lymphocytes may be natural killer (NK) cell clones, plasma cell clones, or show aberrant expression or loss of CD21 marker due to the neoplastic nature of the cells. Further flow cytometry was performed using antibodies against CD3, CD5, CD94, and granzyme B. The combined results indicated that the predominant lymphocyte subset in the PBMCs was CD3−CD5−CD21−CD94−granzyme B−. To confirm monoclonality and exclude the aberrant loss of CD markers, a polymerase chain reaction for antigen receptor rearrangement (PARR) assay was conducted. The PARR assay, using DNA from blood and lymph node samples, showed B-cell monoclonality. Immunocytochemistry using PBMCs showed that the plasma cell marker Multiple Myeloma Oncogene 1 (MUM1) was not expressed. Therefore, the diagnosis was confirmed to be B-cell CLL.

Conclusion
Immunophenotyping can help subclassify the type of lymphoid leukemia; however, as tumor cells can show aberrant expression or loss of the CD21 marker, combining immunophenotyping with the PARR assay could yield a more accurate diagnosis.
Association between the non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) and angina pectoris in US adults: a cross-sectional retrospective study based on NHANES 2009–2018
Authors: Cui Ying , Choi Mankyu 
Published: October 2024

Abstract
Background
The non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) plays a potential role in cardiovascular diseases. However, its association with angina pectoris remains unclear. Herein, we aimed to explore their relationship.

Methods
This cross-sectional retrospective study included the 2009–2018 data from 22,562 adults diagnosed with angina pectoris, retrieved from the National Health and Nutrition Examination Survey (NHANES) database. NHHR was estimated from laboratory data, and angina pectoris diagnosis was ascertained from the NHANES questionnaire.

Results
Angina pectoris risk was greater in the highest than in the lowest NHHR tertile (odds ratio [OR] = 1.61; 95% confidence interval (CI), 1.15–2.54; P = 0.006). Weighted logistic regression showed a positive association between NHHR and angina pectoris in the fully adjusted model (OR = 1.17; 95% CI, 1.07–1.28; P = 0.001). Restricted cubic spline analysis showed a linear association (P = 0.6572). Subgroup analyses indicated no significant differences across different stratifications (P > 0.05, all). Random forest analyses and Boruta algorithm corroborated that NHHR is a strong predictor of angina pectoris. Among the eight machine-learning models evaluated for predictive capabilities, the logistic regression model demonstrated the strongest predictive capability, with an area under the curve of 0.831.

Conclusions
Our study suggests that NHHR is a risk factor for angina pectoris and may be used for risk prediction and to inform future intervention programs to reduce its incidence.
Validation of the Warwick-Edinburgh Mental Well-Being Scale for the Mental Health Surveillance (MHS) of German adults
Authors: Peitz Diana , Thom Julia , Walther Lena , Hoelling Heike , Cohrdes Caroline 
Published: October 2024

Abstract
Background
Mental health encompasses more than just the absence of mental disorders. Thus, a Mental Health Surveillance (MHS) and reporting system for Germany should monitor mental well-being in addition to psychopathology to capture a more complete picture of population mental health. The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) is an internationally established inventory for the integrated assessment of different aspects of mental well-being (i.e., hedonic and eudaimonic) in population samples that has not yet been validated for Germany.

Methods
Using data from a cross-sectional online survey of a convenience sample of N = 1.048 adults aged 18–79 years (51% female) living in Germany, the factorial structure, measurement invariance (age, sex) and psychometric properties of the WEMWBS in its long (14 items) and short (7 items) versions were analyzed. Additionally, correlations to relevant factors (e.g., health-related quality of life, psychological distress) were investigated as indicators of criterion validity.

Results
Means of model fit indices did not confirm a unidimensional factor structure for either version. The three-factor-correlative models showed moderate to good fit while the bifactor model with one general mental well-being factor and three grouping factors fitted the data best. The full range of possible responses was used for all items, and the distribution of both scales was approximately normal. Moreover, the results revealed measurement invariance across sex and age groups. Initial evidence of criterion validity was obtained. Internal consistencies were α = 0.95 and α = 0.89, respectively. Average mental well-being was comparable to that of other European countries at 3.74 for the long version and 3.84 for the short version. While there were no differences by sex, comparisons between age groups revealed higher mental well-being among the older age groups.

Conclusions
Both versions of the WEMWBS showed sound psychometric characteristics in the present German sample. The findings indicate that the instrument is suitable for measuring mental well-being at the population level due to its distributional properties. These results are promising, suggesting that the scale is suitable for use in a national MHS that aims to capture positive mental health in the population as a foundation for prevention and promotion efforts within public mental health.

Published: October 2024

Abstract
Backgrounds
Preoperative imaging, particularly with magnetic resonance imaging (MRI) and computed tomography (CT) scans, plays a crucial role in distinguishing between benign and malignant parotid gland tumors, while the reliability of Ultrasound-Guided Fine Needle Aspiration (FNA) in diagnosing these masses remains a topic of debate.

Methods
This two-center retrospective analysis was conducted on 347 patients with parotid gland tumors who had FNA and preoperative imaging (CT or MRI). All patients underwent surgery and final histopathological examination was available, along with complete medical records between January 2008 and May 2023.

Results
Among the 347 patients, 318 (92%) had benign and 10 (3%) had malignant tumors based on FNA, with 19 (5%) unsatisfactory specimens. Final histological diagnosis revealed 303 (87%) benign and 44 (13%) malignant lesions, with a false-negative rate of 10.6% for FNA. Multivariate analysis identified irregular shape and invasion as independent predictors of malignancy in patient with benign or unsatisfactory FNA results. The odds ratio for irregular shape was 3.06 and for invasion was 12.73.

Conclusion
Imaging characteristics, such as irregular shape and invasion may indicate towards malignant parotid tumors, even in patients with false-negative benign findings in FNA.

Published: October 2024

Abstract
Background
Salmonella, a foodborne pathogen, possesses a type I-E clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated (Cas) system. We investigated the system’s role in regulating Salmonella virulence by deleting the CRISPR arrays and Cas operon.

Results
Our study demonstrates invasion and proliferation defects of CRISPR-Cas knockout strains in intestinal epithelial cells and macrophages owing to the repression of invasion and virulence genes. However, proliferation defects were not observed in the Gp91phox−/− macrophages, suggesting the system’s role in the pathogens’ antioxidant defense. We deduced that the CRISPR-Cas system positively regulates H2O2 importer (OmpW), catalase (katG), peroxidase (ahpC), and superoxide dismutase (soda and sodCI), thereby protecting the cells from oxidative radicals. The knockout strains were attenuated in in-vivo infection models (Caenorhabditis elegans and BALB/c mice) due to hypersensitivity against antimicrobial peptides, complement proteins, and oxidative stress. The attenuation in virulence was attributed to the suppression of LPS modifying (pmr) genes, antioxidant genes, master regulators, and effectors of the SPI-1 (invasion) and SPI-2 (proliferation) islands in knockout strains. The regulation could be attributed to the partial complementarity of the CRISPR spacers with these genes.

Conclusions
Overall, our study extends our understanding of the role of the CRISPR-Cas system in Salmonella pathogenesis and its virulence determinants.

Abstract
Background
Rasburicase, a recombinant urate oxidase enzyme, has potent efficacy in controlling uric acid and is widely used to prevent tumor lysis syndrome in high-risk patients owing to its low toxicity profile. However, it has been associated with a risk of anaphylaxis, especially on re-exposure, owing to its immunogenic potential.

Case presentation
A 71-year-old Japanese female diagnosed with diffuse large B cell lymphoma with a large tumor burden experienced anaphylactic shock leading to death upon initial administration of rasburicase. The pre-and postmortem examination revealed that the cause of death was a cascade of events starting with anaphylaxis-induced distributive shock leading to obstructive shock due to the collapse of the heart, which was compressed by the post-mediastinal tumor. This was further compounded by massive bleeding from the tumor and tension hemothorax, resulting in circulatory collapse.

Conclusions
Although extremely rare, rasburicase can cause fatal anaphylaxis, even on first exposure.
