Abstract

Background: For the past two decades, the Copenhagen Psychosocial Questionnaire (COPSOQ) has been established as a valid instrument to measure psychosocial stress at work. Nowadays, the COPSOQ international network is responsible for the monitoring and improvement of COPSOQ. 2019, a new questionnaire was published, and the Greek version is now being validated.
Methods: Measurement qualities of the Greek COPSOQ III have been explored in adherence to the usual requirements of a validation study as defined by DIN EN ISO 10075-3. A sample of observations from 2.189 participants surveyed with the COPSOQ in Greece was used to validate the current version with appropriate statistical analyses. Exploratory factor analysis was used to assess statistical relations for many scales.
Results: With its 108 items and 40 scales, the Greek COPSOQ III includes all psychosocial work factors that have been internationally validated and remain compatible with about 72% of the COPSOQ III German version content. Beyond primary results, congruence with widely used theoretical approaches like the Demand-Control(−Support) model (DCM) or the Job Demands-Resources model (JDR) is generally satisfactory. In summary, our validation study for the Greek COPSOQ III version showed adequate reliability and validity, which is in line with the COPSOQ III questionnaire from other European countries, and it is also compatible with the validation of the German COPSOQ III (Lincke, 2021). Our regression analysis showed that the 34 psychosocial work factors (34 “context” scales) could adequately predict the scores of the satisfactory and health scales (6 “outcome” scales). The analysis also indicated the top five (5) predictors (context variables) for each of the six (6) “effect” scales (outcome variables).
Conclusions: With the launch of COPSOQ III in Greece, current and new workplace psychosocial aspects could be explored. COPSOQ III(GR) is a beneficial instrument for enterprise research and risk assessment.

Abstract

Purpose:To evaluate the outcomes of surgical treatment in adult and pediatric patients with postcorrosive gastric outlet obstruction (GOO) in Yemen.
Patients and Methods: A prospective observational study was conducted at the Al-Thawra Modern General Hospital in Sana'a, Yemen, from January 1, 2019, to January 31, 2023. The study included 77 patients, including both adults and children, who were admitted for surgical treatment of postcorrosive GOO. Data was collected from medical records, patient interviews, and follow-up visits.
Results: Among the 77 patients, 77% (n=59) were pediatric patients and 23% (n=18) were adults. The mean age of the cohort was 10.6 years, with an average age of 4.12 years for pediatric patients and 30.8 years for adults. Accidental ingestion of acidic substances was the primary cause of postcorrosive GOO (97% of cases). Universal symptoms at presentation included vomiting, early satiety, and weight loss. Definitive surgery was performed in one stage in 95% of patients, with Mikulicz pyloroplasty being the most common procedure (82%) in pediatric cases, whereas gastrojejunostomy was mainly used in adults (67%). Postoperative complications occurred in 22% of patients, with vomiting, wound infection, and aspiration pneumonia being the most common. Anastomotic restricture occurred in two pediatric patients who required reoperation. The overall mortality rate in one pediatric patient was 1.3%. Improvement in GOO symptoms were observed in 96% of patients. Pediatric patients had a longer median hospital stay (6.5 days) than adult patients (6 days).
Conclusion: Corrosive injuries, particularly in the pediatric population, are a significant issue in Yemen due to the unsafe storage of sulfuric acid. Early surgical intervention within 4 weeks after ingestion is recommended to prevent weight loss and prolong hospitalization. Further research and interventions are needed to prevent such injuries, improve public awareness, and regulate the sale and storage of corrosive substances.

Abstract

Background:Public health experts currently agree that heated tobacco products (HTPs) pose a significant health risk for their consumers. The same concentrations and speed of delivery of nicotine found for HTPs and conventional combustion cigarettes make it necessary to consider the addictiveness of HTPs, and provide precise diagnostic instruments to serve as the basis for effective treatment plans. Therefore, the main objectives of this study were to design a questionnaire for HTPs addiction called “HeatedTobaccoProductsAddictionQuestionnaire (HeaTPAQ)” and to examine its psychometric properties.Methods:Adults from the general population of Lebanon (n = 754) were administered the HeatPAQ, along with the Fagerström test for nicotine dependence (FTND), the Generalized Anxiety Disorder 7-item, and the Patient Health Questionnaire-9. We split the main sample into two subsamples; subsample 1 consisting of 33% of the participants used for the exploratory factor analysis (EFA) (n=246; mean age 27.82±9.38 years) and subsample 2 consisting of 67% of the participants used for the confirmatory factor analysis (CFA) (n=508; mean age 27.81±8.80 years).Results:EFA then CFA analyses revealed a one-factor model consisting of 13 items with acceptable fit to the data. The HeaTPAQ reached excellent internal consistency coefficients, with both Cronbach’s α and McDonald’s ω values of .96. The one-dimensional structure of the HeaTPAQ was found to be invariant across sex groups. Convergent validity was demonstrated through significant positive correlation with FTND scores. Furthermore, HeaTPAQ scores correlated positively with measures of anxiety and depression, which suggests the adequate concurrent validity of the scale.Conclusion:Findings suggest that the HeatPAQ is a specific, short and simple-to-use self-report questionnaire to assess HTPs addiction reliably and validly. We hope that the HeatPAQ will facilitate routine screening for HTPs addiction, which is an essential step towards appropriate prevention and intervention efforts and to inform policy makers.
A Riemannian Inexact-Newton Method for Solving the Orthogonal INDSCAL Problem in Multidimensional Scaling
Authors: Zhou Xue-lin , Li Chao-qian , Li Jiao-fen 
Published: August 2024

Abstract

The well-known individual differences scaling (INDSCAL) model is intended for simultaneous metric multidimensional scaling (MDS) of several doubly centered matrices of squared dissimilarities. In this work, the problem of fitting the orthogonal INDSCAL model to the data is reformulated and studied as a matrix optimization problem on the product manifold of orthonormal and diagonal matrices. A Riemannian inexact Newton method is proposed to address the underlying problem, with the global and quadratic convergence of the proposed method established under some mild assumptions. Furthermore, the positive definiteness condition of the Riemannian Hessian of the objective function at a solution is derived. Some numerical experiments are provided to illustrate the efficiency of the proposed method.

Abstract

The discovery of a new, strong reaction channel of the deuteron-deuteron fusion at very low energies might have major consequences for the construction of a future clean and efficient energy source. Following the first theoretical and experimental indications for the existence of the deuteron-deuteron threshold resonance in the 4He nucleus and its dominant decay by the internal e+e- pair creation, we present here an extensive experimental study confirming emission of high-energy electrons and positrons. A simultaneous use of Si charged particle detectors of different thicknesses and large volume NaI(Tl) and HPGe detectors has allowed for the first time to determine the branching ratio between emitted protons, neutrons and e+e- pairs for deuteron energies down to 5 keV. The high-energy positrons could be unambiguously detected by their bremsstrahlung spectra and annihilation radiation, supported by the Monte Carlo Geant4 simulations. The theoretical calculations, based on a destructive interference between the threshold resonance and the known broad resonance in 4He, agree very well with experimentally observed increase of branching ratios for lowering projectile energies. The partial width of the threshold resonance for the e+e- pair creation should be at least 10 times larger than that of the proton channel.

Abstract

Objective: In TIA and stroke patients with carotid stenosis, estimations of future ipsilateral ischemic stroke risk and treatment decisions are currently primarily based on the degree of stenosis. Intraplaque hemorrhage (IPH), which can be readily visualized on carotid MRI, is increasingly established as an easy to assess and a very strong and independent predictor for ipsilateral stroke risk, stronger than any clinical risk factor. We developed a clinical prediction model (IMPROVE) incorporating IPH, degree of stenosis, and clinical risk factors to select patients with symptomatic carotid stenosis at high risk for stroke.
Methods: IMPROVE was developed on pooled clinical and MRI data from five cohort studies of 760 recent TIA or minor stroke patients with carotid plaque who received optimal medical treatment. We used Cox proportional hazards models to determine the coefficients of IMPROVE. IMPROVE was internally validated using bootstrapping and converted to one- and three-year ipsilateral ischemic stroke risk.
Results: The development dataset contained 65 ipsilateral incident ischemic strokes that occurred during a median follow-up of 1.2 years (IQR: 0.5-4.1). The IMPROVE model includes five predictors, which are in order of importance: degree of stenosis, presence of IPH on MRI, classification of last event (cerebral vs ocular), sex, and age. Internal validation revealed a good accuracy (C-statistic: 0.82; 95% CI: 0.77–0.87) and no evidence for miscalibration (calibration slope: 0.93).
Interpretation: Using presence of IPH on MRI and only four conventional parameters, the IMPROVE model provides accurate individual stroke risk estimates, which may facilitate stratification for revascularization.
Gender in mineral names

Abstract
Minerals are the fundamental constituents of Earth, and mineral names appear in scientific literature for disciplines including geology, chemistry, materials science, biology, and medicine, among others. Choosing a name is the full responsibility of the authors of new mineral proposals submitted to the International Mineralogical Association (IMA). Scientific nomenclature and its traditions have evolved over time, and consequently, mineral names track changes in the landscape of mineralogy with respect to language, technology, and culture. To evaluate these changes, the namesake information for all 5896 minerals approved by the IMA or “grandfathered” into use as of December 2022 was recorded and categorized within a workable database. The compiled information yields diverse insights into the intersection of science and culture and could also be used to project future trends. In this study, we used the name database to investigate gender diversity among mineral eponyms.
More than half (ca. 54%) of all mineral species are named after people, the identities of whom are largely a reflection of the people that have historically been involved, in one way or another, in the geosciences and the mining industry. Of the 2738 people with minerals named for them, ∼6.1% are (interpreted to be) women. Nearly all minerals named for women were named during the last 60 years, although the growth rate in the year-on-year percentage of women among new mineral namesakes has slowed since about 1985. If current and historical trends hold, our model predicts that women will not comprise more than about 10.35% of newly established mineral namesakes in future years. The representation of women among mineral namesakes also differs starkly among countries. For example, Russians comprise 43.11% of women with minerals named for them but account for only 15.12% of all eponyms. However, there are additional disparities beyond the proportions of namesakes. For scientists who were alive when a mineral was named for them, women averaged 3.74 years older than men when evaluated over the same timespan (1954–2022). These results demonstrate that gender-based disparities are imprinted into current mineral nomenclature and indicate that gender parity among new mineral namesakes is impossible without unprecedented changes in the upstream demographics that are most likely to affect naming trends.

Abstract
Al-hematite occurs in a wide range of terrestrial soils, but the impact of hydrologic factors on the formation and preservation of Al-hematite remains uncertain. Experimental studies indicate that the ratio of the intensity (I) of the (110) reflection to the intensity of the (104) reflection [(I(110)/I(104)] increases with increasing Al content in a series of synthetic Al-hematite analyzed by X-ray Diffraction (XRD), whereas the ratio of the full-width at half maximum (W) of the (110) reflection to the full-width at half maximum of the (104) reflection [W(110)/W(104)] decreases. Quantitative constraints were applied to determine the various levels of Al-substituted hematite in a basaltic laterite (a 48-m-long drill hole) from Hainan Island in South China. The spatial correlation between the distribution of hematite with varying Al content and the location of the groundwater table in the basaltic laterite indicates that hydrologic conditions play a crucial role in regulating the formation and preservation of Al-hematite. The weathering of basalt in a stable water-saturated environment with a relatively slower flow rate promotes the formation of Al-poor hematite. Conversely, the formation of Al-rich hematite was favored by a relatively high flow rate and alternating wet and dry conditions above the groundwater table. Additionally, capillary water in the surficial soil facilitates the expulsion of Al during the recrystallization of Al-rich hematite, resulting in the formation of Al-poor hematite in the surficial soil. Observations from landed instruments and ground-based telescopes have led to the longstanding suspicion that Al-hematite exists on the surface of Mars. The potential presence of Al-hematite in certain martian outcrops may suggest the existence of transient liquid water with slightly higher flow rates, such as episodic floods, emphasizing the dynamic hydrologic conditions on Mars. Moreover, this study suggests that visible and near-infrared (VNIR) spectroscopy can be employed to identify and characterize Al-rich hematite. This approach could be employed to assess the potential presence of Al-rich hematite on Mars, aiding in the study of the planet’s hydrologic environment.

Published: August 2024

Biology learning is closely related to conceptual understanding. Incorrect understanding of students if not immediately corrected can lead to misconceptions. This study aims to analyze and identify the causes of students' misconceptions about cell material using a four-tier diagnostic test with the CRI method. This type of research is descriptive quantitative research. The population used was all students of class XI MA Darul Muqorrobin Kendal. The research subjects were 52 students using purposive sampling technique. Data collection techniques using tests, interviews, questionnaires and documentation. The results of the data analysis showed that the percentage of students who had misconceptions was 51%, understood the concept 22%, guessed 10% and did not understand the concept 17%. While the highest misconception for each sub material is 60% in protein synthesis. The percentage of factors that cause misconceptions from students is 60%, teachers are 44%, learning methods are 66%, teaching context errors are 48%, and textbooks are 40%. Based on the results of this analysis, misconceptions still often occur in cell material, so further research is needed on other materials.
Herlyn-Werner-Wunderlich Syndrome Accompanying Hemosalpinx and Endometriotic Ovarian Cyst suspected as Tubo-Ovarian Abscess: A Rare Congenital Anomaly of Genitourinary System in a 12-year-old Female Patient
Authors: Kim Hayeon , Park So Hee , Choi Jeong In , Chung Soo-Ho , Sang Jae Hong 
Published: August 2024

Introduction:
The Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital
anomaly of the Mullerian duct and Wolffian duct with three symptoms of uterus: didelphys, obstructed
hemivagina, and ipsilateral renal agenesis. In this syndrome, hydrometrocolpos or hematocolpometra,
which are clinically equivalent to colpatresia, causes mass and pain.

Case Presentation:
This case reports a case of HWW syndrome with a left adnexal mass suspected
as a tubo-ovarian abscess found on an abdominal CT image in a 12-year-old female patient who
visited our hospital with the main complaint of lower abdominal pain and fever.

Conclusion:
A patient with HWW syndrome may be admitted to the emergency room with abdominal
pain, though it is a rare case. This syndrome is manifested as abdominal pain and a mass
due to hematocolpometra, mainly in women after puberty. For an adolescent female with ipsilateral
renal agenesis accompanied by abdominal pain and mass, the diagnostic imaging test may be performed,
considering HWW syndrome and precise surgical treatment should be planned.
Depression and the Glutamate/GABA-Glutamine Cycle
Authors: Mamelak Mortimer 
Published: August 2024

:
Many features of major depressive disorder are mirrored in rodent models of psychological
stress. These models have been used to examine the relationship between the activation of the hypothalamic-
pituitary axis in response to stress, the development of oxidative stress and neuroinflammation,
the dominance of cholinergic neurotransmission and the associated increase in REM sleep pressure.
Rodent models have also provided valuable insights into the impairment of glycolysis and brain
glucose utilization by the brain under stress, the resulting decrease in brain energy production and the
reduction in glutamate/GABA-glutamine cycling. The rapidly acting antidepressants, scopolamine,
ketamine and ECT, all raise extracellular glutamate and scopolamine and ketamine have specifically
been shown to increase glutamate/GABA-glutamine cycling in men and rodents with corresponding
short-term relief of depression. The nightly use of gammahydroxybutyrate (GHB) may achieve more
permanent results and may even act prophylactically to prevent the development or recurrence of depression.
GHB is a GABAB agonist and restores the normal balance between cholinergic and monoaminergic
neurotransmission by inhibiting cholinergic neurotransmission. It relieves REM sleep pressure.
GHB’s metabolism generates NADPH, a key antioxidant cofactor. Its metabolism also generates
succinate, the tricarboxylic acid cycle intermediate, to provide energy to the cell and to synthesize glutamate.
In both animals and man, GHB increases the level of brain glutamate.
Quelles perspectives pour Israël après la guerre?

Après avoir été marginalisé pendant près d’une décennie par les conséquences des Printemps arabes, le conflit israélo-palestinien est de nouveau au coeur des préoccupations de la communauté internationale. Le 7 octobre2023, le Hamas a lancé l’assaut le plus sanglant de son histoire contre les localités et les installations militaires israéliennes situées en périphérie de la Bande de Gaza. En réaction, les Forces de Défense d’Israël (« Tsahal » enhébreu) ont mené une offensive destructrice à grande échelle à l’intérieur de l’enclave. À l’heure où les deux protagonistes semblent déterminés à poursuivre l’affrontement pour consolider leurs acquis respectifs, cet articlese propose d’explorer les perspectives qui se présentent à Israël à l’issue de cette guerre*.*Le présent article » est l’actualisation en langue française de l’article de Berger, Chloé et Leroy, Didier, « WhatProspects for Israel after the war?, » e-Note 56 (Institut royal supérieur de défense), 15 mars 2024, https://www.defence-institute.be/en/publications-2/e-note/e-note-56/.
