Published: August 2023

Sarcomatoid carcinoma of the pancreas is a rare malignancy characterised by a predominant sarcomatoid component associated with a well-differentiated adenocarcinomatous component. We report the case of an 84-year-old patient with a history of cardiac arrhythmia who was admitted to hospital with jaundice of one month's duration. Ultrasound and abdominal computed tomography revealed a solid and locally advanced pancreatic head mass. The patient underwent endoscopic ultrasound with biopsy of the mass and placement of a biliary stent. Pathological examination of the biopsy revealed a sarcomatoid carcinoma of the pancreas. In view of the patient's bedridden condition and comorbidities, it was decided at a multidisciplinary consultation meeting to withhold treatment. The patient died 1 month later.

Published: August 2023

Abstrak: Studi ini mengkaji konsep ilmuwan Muslim tentang klasifikasi ilmu. Studi ini merupakan studi kepustakaan. Data didasarkan pada sumber-sumber tertulis dan otoritatif. Studi ini didasari oleh fakta bahwa Islam mewajibkan setiap Muslim menuntut ilmu. Alquran maupun hadis memberikan petunjuk bahwa Islam merupakan agama yang memandang penting ilmu. Aktivitas membaca menjadi kegiatan penting menurut Alquran, dan ini bisa dilihat dari fakta bahwa ayat pertama yang diturunkan kepada Nabi adalah berkaitan dengan kegiatan membaca (iqra’). Nabi dalam berbagai hadisnya juga memberi isyarat tentang kewajiban dan keutamaan menuntut dan mengembangkan ilmu. Studi ini menunjukkan bahwa para pemikir Muslim merinci pandangan Alquran dan hadis tentang ilmu yang wajib dipelajari. Studi ini akan mengungkap pandangan al-Ghazâlî, Quthb al-Dîn al-Syîrâzî, Ibn Khaldûn, Ibn al-Qayyim al-Jauziyah dan Syed Muhammad Naquib al-Attas. Pendapat mereka mengarah pada kesimpulan bahwa Islam mewajibkan kaum Muslim untuk menuntut dan mengembangkan ilmu yang bermanfaat bagi dunia Muslim, baik ilmu syariah maupun ilmu filsafat. Studi ini turut memperkuat gugusan referensi tentang kajian epistemologi Islam di Indonesia.

Published: August 2023

The decolourisation of the reactive Congo red dye from synthetic wastewater was studied using ElectroCoagulation (EC) technique. In an effort to increase removal efficiency, the effects of operating parameters including flow, inter electrode distance, conductivity, voltage, and Hydraulic Detention Time (HDT) were investigated. An electrochemical cell was initially created with an aluminum cathode and anode. Following that, each variable's impact was examined independently using synthetic wastewater. The colour removal efficiency was 93% when the initial dye concentration was 4 mg/L, the conductivity was 300 ppm, the temperature was 24 oC, the interelectrode spacing was 1 cm, and the HDT of the electrolysis was 120 min.
HDAC3 is modestly differentially expressed in central nervous system metastasis.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published microarray and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We observed modest differential expression of histone deacetylase 3, encoded by HDAC3, among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of HDAC3 in CNS metastasis in patients with lung cancer. HDAC3 mRNA was present at increased quantities in metastasis to the brain in humans with lung cancer. However, high expression of HDAC3 in primary tumors of the breast was favorably correlated with patient distant metastasis-free and recurrence-free survival. Modulation of HDAC3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.

IL15 is differentially expressed in central nervous system metastasis.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published RNA-sequencing and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that interleukin-15, encoded by IL15, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of IL15 in CNS metastasis in patients with lung cancer. IL15 mRNA was present at decreased quantities in metastasis to the brain in humans with lung cancer. Primary tumor expression of IL15 was not correlated with overall, distant metastasis-free, recurrence-free survival in patients with breast cancer. Modulation of IL15 expression may be relevant to the biology by which tumor cells metastasize from the primary organ site to the brain in humans with cancer of the lung and breast.

Authors: Hernández Juan Carlos Pacho , Gutiérrez José Luis González , Yunta-Rua Laura , Pocinho Ricardo , López Almudena López
Published: August 2023

Objective: Cognitive reappraisal and distraction modulate pain; however, little is known about their effectiveness at different levels of pain intensity. Thus, the aim of this study has been to analyze the differential efficacy of both strategies to reduce perceived pain intensity and pain unpleasantness in low and moderate pain levels. Methods: 3 (Emotion regulation strategy: cognitive reappraisal, distraction, and control) by 2 (Intensity of the painful stimuli: low and moderate intensity) by 2 (time: pre-test and post-test) mixed factorial design. Ninety healthy adults were randomly assigned to one of six experimental conditions, pain was induced using an advanced thermal stimulator. All participants completed the experimental pre-test and post-test phases, in each phase twelve pain stimuli were administered. At the end of each pain stimulus, participants rated the level of perceived pain intensity and pain unpleasantness experienced during the painful stimulation using the CoVAS. Data were collected from May 2022 to November 2022. Results: Analyses of covariance (ANCOVA), showed that at post-test (n = 90), cognitive reappraisal and distraction were equally effective in reducing perceived pain intensity in low pain levels, whilst distraction was more effective than cognitive reappraisal in decreasing perceived pain intensity in moderate pain levels. Neither distraction nor cognitive reappraisal were effective in decreasing pain unpleasantness. Conclusions: These findings highlighted the beneficial use of both strategies in the short-term for pain relief, being more effective distraction in moderate pain levels. Applying both strategies to everyday situations that may cause short-term acute pain could be of great clinical relevance.

Published: August 2023

We investigated lower secondary school students’ (N = 511, M age = 15.3 years, girls 51.9%) perfectionistic profiles, profile stability during the ninth grade, and how profile stability and transitions relate to students’ well-being. Using latent profile analysis, students were classified according to their perfectionistic strivings and concerns (measured with SAPS). Four profiles were identified: moderately concerned, perfectionists, ambitious, and non-perfectionists. Latent transition analysis indicated substantial stability in the profiles (transition probabilities: .78–.87). Around 82% of students held stable profiles over time, but significant transitions were also found: from moderately concerned to non-perfectionists or perfectionists, and from perfectionists to moderately concerned. Although ambitious and perfectionists were highly engaged, perfectionists displayed higher burnout, anxiety, and depressive symptoms. Also, the transitions were meaningfully linked to well-being. For example, transitioning from moderately concerned to perfectionists was related to higher exhaustion. The findings highlight the crucial role of perfectionistic concerns on students’ well-being.
Saintly fund managers cannot earn a license to make sinful investments
Authors: Niszczota Paweł , Conway Paul
Published: August 2023

Can investment fund managers earn a license to invest unethically? Past moral behavior can provide a perceived license to behave less morally, yet people may expect ethical consistency. In four experiments (N = 2,677), we examined whether people license ethical fund managers to engage in ethically questionable ‘sin stocks’—or whether people view ethical fund managers making ethically questionable investments as hypocritical. We investigated both same-domain (past ethical investment) and cross-domain (distinguished military service) evidence for the fund manager’s moral character and earning via both traditional investing and ‘shorting’ sin stocks. We found no evidence of a moral license for ethical investors to earn money off sin stocks (even by shorting them). In contrast, people rated ethical fund managers as less permitted to invest in such stocks, consistent with expectations of ethical commitment—a finding partially mediated by perceived hypocrisy. Hence, people expect ethical fund managers to maintain high ethical investment standards.
No evidence that Chinese playtime mandates reduced heavy gaming in one segment of the video games industry

Published: August 2023

Governments around the world are considering regulatory measures to reduce young people’s time spent on digital devices, particularly video games. This raises the question of whether proposed regulatory measures would be effective. Since the early 2000s, the Chinese government has been enacting regulations to directly restrict young people’s playtime. In November 2019, it limited players aged under 18 to 1.5 hours of daily playtime and 3 hours on public holidays. Using telemetry data on over seven billion hours of playtime provided by a stakeholder from the video games industry, we found no credible evidence for overall reduction in the prevalence of heavy playtime following the implementation of regulations: individual accounts became 1.14 times more likely to play heavily in any given week (95% confidence interval 1.139–1.141). This falls below our preregistered smallest effect size of interest (2.0) and thus is not interpreted as a practically meaningful increase. Results remain robust across a variety of sensitivity analyses, including an analysis of more recent (2021) adjustments to playtime regulation. This casts doubt on the effectiveness of such state-controlled playtime mandates.
The Effect of Sense of Agency on Self-Efficacy Beliefs: A Virtual Reality Paradigm
Authors: Alsaleh Ala , Schubert Moritz , Endres Dominik
Published: August 2023

A sense of control over the environment can stem from mere motor control to overarching belief systems of control. Sense of agency is defined as perceiving oneself as the cause of an action or its effects. It can be conceptualized as the low-level experience of online motor control over one's actions. Self-efficacy is the high-level belief in one's ability to achieve intended goals. Both constructs have been frequently studied on their own, but this is the first study that empirically investigates a possible link between the two. To this end, we conducted a virtual reality (VR) experiment in which participants had to trace shapes while experiencing both movement and feedback distortions. The experiment used a 2x2 design with the first factor being the translation of the participant's movements into VR (accurate vs distorted) and the second factor being feedback upon task completion (real vs hyper-positive). We found that these two factors manipulated the sense of agency and, in turn, influenced self-efficacy, and see this as a first step in the investigation of a possible causal link between the two constructs. Thus, the constructs of agency and self-efficacy appear more closely linked than previous research suggests. Future research targeting the sense of agency as a bottom-up influence on self-efficacy beliefs holds promising implications for both clinical and positive psychological interventions as well as motor rehabilitation.

Ibero-American journalism in the face of scientific disinformation: Fact-checkers’ initiatives on the social network Instagram
Authors: Martín-Neira Juan-Ignacio , Trillo-Domínguez Magdalena , Olvera-Lobo María-Dolores
Published: August 2023

The fight against disinformation is one of the major battles that journalism has had to face in recent years, especially after the coronavirus pandemic. As a counterbalance, “fact-checker” news media –platforms that have an important role in verifying whether or not the content circulating is true and that have harnessed the benefits of social networks, in spite of the difficulties inherent in these applications, to disseminate reliable and fact-checked content– have emerged. This study aims to explore how 10 prominent fact-checking accounts in Ibero-America use the social network Instagram to debunk false information, focusing in particular on the field of science and health. Applying a content analysis method using a checklist with quantitative and qualitative indicators, a total corpus of 240 posts from the first half of 2022 was obtained. The results allow us to determine which type of hoax has been used most as well as whether Twitter, Facebook, and WhatsApp are used for its dissemination. It was observed that health topics are the ones that attract the greatest interest from fact-checker accounts when it comes to creating fact-checks, and they tend to use static images or slide mode as opposed to video. In addition, they tend to use formal language in their presentation. This study also reveals that there were no instances of interaction with followers. While fact-checker accounts extensively use Instagram owing to its visual capabilities, they do not necessarily take advantage of its graphic potential. In addition, it was concluded that coronavirus is still a relevant topic for fact-checker media outlets, which must constantly refute the hoaxes that are mostly spread through social networks.

The objective of this study was to evaluate the frequency of contraceptive administration carried out by tutors in domestic cats. The work was carried out in veterinary clinics in João Pessoa, Paraíba, Brazil. For that, a structured questionnaire was given out to cat tutors in two veterinary clinics, seeking to collect information on the frequency and age at which contraceptives are administered, side effects in their pets, as well as the possible side effects, adverse events and knowledge about the risks they pose to the animal. A total of 50 tutors were interviewed, where it was identified that the ages at which the cats most received contraceptives was between 1 and 3 years old, and 78% of the tutors use or would use these drugs to avoid pregnancy in females. It was observed that 79% of the tutors use the drugs even though they are aware of the undesirable side effects, and revealed that the reason for using them would be financial, since castration would cost more. About 90% of those tutors use the injectable form of the drugs and most (85%) buy them freely in pet shops. It is concluded that the use of contraceptives in cats has a high percentage, even with the tutors’ knowledge of the risks in continuous use, such as pyometra or neoplasms. It is also concluded that these drugs are easily sold in Agricultural house and that most are not administered by veterinary doctors.

Published: August 2023

Gastric neoplasms are less prevalent in dogs and cats, and manifest as loss of appetite, weight loss, vomiting (with or without blood), polyuria, polydipsia and bloody stools, leading to anemia. Helicobacter spp. is a Gram-negative, spiral-shaped, flagellated bacterium that infects the gastric mucosa of humans and animals such as dogs and cats. Helicobacter spp is the cause of several diseases of varying severity. Studies have demonstrated the relationship of this bacterium with human gastritis, gastric and duodenal ulcers, and gastric tumors. Despite occurring in humans, the relationship between these tumors and dogs is considered inconclusive, mainly due to the lack of research. The present report describes the clinical evaluation of a patient diagnosed with undifferentiated sarcoma due to probable infiltration of Helicobacter spp. in the antral pyloric region, which is considered a rare form of presentation in dogs. It is noteworthy that the diagnostic complexity of these cases is related to the lack of specificity of the clinical signs and the need for a biopsy to confirm the diagnosis.

Solving the problem of improving the training process of qualified sprinters on the basis of a comprehensive assessment of physical fitness, various approaches to its study, and the diversity of its aspects is an actual direction that requires its further study. The purpose of the study is to develop and experimentally test the method of comprehensive control of the physical fitness of qualified sprinters in the annual cycle of training. Research methods: analysis, generalization and systematization of scientific literature data, pedagogical research methods (pedagogical observation, pedagogical testing, pedagogical experiment), mathematical methods of processing the obtained results. Research results. The use of staged, operational and ongoing control of the physical training process made it possible to effectively make adjustments to the volume and intensity of training work in order to improve the necessary indicators of physical fitness and bring them closer to the model values for each period of training. At the end of the one-year training cycle, the athletes of the experimental group in the running test exercises increased their performance from 2.52 to 10.4%; in jumping exercises, the increase in results was from 2.82 to 4.05%; in exercises for demonstrating strength abilities, the increase in results was from 5 to 5.14% (p<0.05), and in the test for demonstrating flexibility - 5.71%. Conclusions. The analysis of the data obtained during the experiment shows that the proposed method of monitoring the physical fitness of track and field athletessprinters is quite acceptable for practice, is effective and can be recommended for use in the training process of short-distance runners.

OBJECTIVE

The optimal extent of resection of craniopharyngiomas to minimize the long-term risks of hypothalamic and endocrine dysfunction (obesity and panhypopituitarism) in children remains uncertain. The purpose of this study was to report long-term outcomes of pediatric patients with craniopharyngioma undergoing surgical treatment and to study rates of endocrinological and hypothalamic dysfunction in association with extent of resection.

METHODS

This retrospective study was performed in a cohort of children who underwent resection for craniopharyngioma at Children’s of Alabama between 1990 and 2020. The primary outcome was hypothalamic dysfunction defined as a 0.5 increase in body mass index (BMI) Z-score and as a BMI > 2 SDs with or without psychiatric disturbances. Univariable analysis was performed using ANOVA, Wilcoxon rank-sum test, Pearson’s chi-square test, and Fisher’s exact test as appropriate. Missing data on the primary outcome were handled via multiple imputations. Relative risks were estimated using a multivariable generalized linear model with a priori variables selected using a modified Poisson regression approach with robust error variance to estimate risk ratios.

RESULTS

The cohort includes 39 patients (24 girls and 15 boys; age range 1 month–16 years) who underwent resection of craniopharyngioma at the authors’ center between 1990 and 2020. The preoperative goal of treatment was cyst decompression (CD) in 5, subtotal resection (STR) in 13, and gross-total resection (GTR) in 21 patients. The median long-term follow-up after surgery was 8.11 years (average 8.21, range 0.4–24.33 years). Univariate analysis demonstrated a statistically significant increase in hypothalamic dysfunction in patients undergoing GTR when compared to those undergoing STR or CD at 1 month postoperatively (p = 0.006) and 6–11 months postoperatively (p = 0.010), but with this difference not persisting beyond 1 year. Multivariable analysis showed patients older than 10 years at time of surgery to be the most affected and at highest risk of developing significant hypothalamic dysfunction. There was no significant difference in pituitary or neurological function between the STR/CD and GTR groups at 12–24 months or at most recent follow-up. There was no significant difference in BMI Z-scores between the STR/CD and GTR groups at 6–12 months or at most recent follow-up.

CONCLUSIONS

Both STR and GTR of craniopharyngioma were associated with significant endocrinological sequelae after 1 year. These potential complications should be discussed with patients and their families, and postoperative protocols should include early nutritional and endocrinological interventions with endocrinologist consultation.

OBJECTIVE

Chronic subdural hematomas (CSDHs) are the among the most common conditions treated by neurosurgeons. Midline shift (MLS) is used as a radiological marker of CSDH severity and the potential need for urgent surgical evacuation. However, a patient’s age may affect the degree of MLS for a given hematoma volume. This study aimed to investigate the correlation between the patient’s age and the MLS caused by CSDH.

METHODS

The database of patients treated for CSDH was reviewed in a single institution. Patients with unilateral CSDH were included. To measure CSDH volume, the preprocedural head CT scans underwent 3D volumetric reconstruction using the TeraRecon software. The effect of age on MLS after adjusting for CSDH volume was investigated using linear regression analysis.

RESULTS

Sixty-nine hematomas in 69 patients were included. The age of patients ranged from 25 to 94 years (mean 71.6 years). Hematoma volume and MLS ranged from 27.8 to 215 mL (mean 99.3 mL) and 0–17 mm (mean 6.5 mm), respectively. On multivariate regression analysis, MLS showed a significant independent negative correlation with age after adjusting for CSDH volume (OR −0.11, 95% CI −0.16 to −0.06; p < 0.001), meaning that for a fixed CSDH volume, with each 10-year increase in age the MLS will reduce by 1.1 mm. Moreover, MLS-to-volume ratio showed a significant negative linear correlation with age (r2 = 0.32; p < 0.001). Ten-milliliter increments in CSDH volume resulted in a 1.09-mm increase in MLS in patients younger than 60 years, which is 2.4-fold higher compared to the 0.46-mm increase in those older than 75 years (p < 0.001).

CONCLUSIONS

For a fixed CSDH volume, older age correlates with significantly lower MLS. This could be explained by higher parenchymal compliance in older individuals due to increased brain atrophy, and a larger subdural space. Clinical use of MLS to estimate severity of CSDH and gauge treatment decisions should take the patient’s age into account.
Bilateral brain microstructural alterations in patients with left-sided classic trigeminal neuralgia: a diffusion kurtosis imaging study

OBJECTIVE

White matter microstructural abnormalities in patients with classic trigeminal neuralgia (TN) have been observed. However, the impact of classic TN in both hemispheres, the difference and extent of alterations in bilateral hemispheres, and the relationship between the impaired area and pain conduction are not fully understood. The purpose of this study was to investigate brain microstructural alterations and compare the bilateral hemispheres in patients with unilateral classic TN, as well as to explore their clinical implications.

METHODS

The authors performed a cross-sectional study of 36 patients with left classic TN (TN group; age 40–66 years) and 36 healthy controls (HC group; age 40–66 years). Diffusion kurtosis imaging (DKI; b-values = 0, 1250, and 2500 sec/mm2) was performed in all patients using a 3T MRI scanner. The FMRIB Software Library with tract-based spatial statistics was used to analyze intergroup differences in both hemispheres. Atlas-based region of interest analysis was conducted in fiber tracts and gray matter structures.

RESULTS

Decreased fractional anisotropy (FA) and increased mean diffusivity in 2.70% and 5.34% of white matter regions, such as the corona radiata, corpus callosum, internal capsule, superior longitudinal fasciculus, and cingulum, were detected in the TN group compared with the HC group (p < 0.05, family-wise error correction). Reduced mean kurtosis (MK), axial kurtosis, and radial kurtosis were detected in the bilateral thalamus in TN patients. The FA and MK values decreased asymmetrically in both cerebral hemispheres. Atlas-based region of interest analysis revealed more pronounced FA and MK reductions in the left thalamus and posterior corona radiata. There were negative associations of disease duration and pain intensity with the MK values in the thalamus, internal capsule, and superior corona radiata.

CONCLUSIONS

The authors concluded that unilateral TN could have asymmetrical microstructural alterations in bilateral hemispheres, which might be due to the compromised fiber tract integrity and abnormal neurons and synapses. The thalamus could be an important relay station in the pain conduction and modulation pathway and could have microstructural abnormalities in both the left and right sides. DKI could provide important information on the CNS pathophysiology of TN and assist in prognostic evaluation.

OBJECTIVE

Ulnar neuropathy at the elbow (UNE) is common, affecting 1%–6% of the population. Despite this, there remains a lack of consensus regarding optimal treatment. This is primarily due to the difficulty one encounters when trying to assess the literature. Outcomes are inconsistently reported, which makes comparing studies or developing meta-analyses difficult or even impossible. Thus, there is a need for a core outcome set (COS) for UNE (COS-UNE) to help address this problem. The objective of this study was to utilize a modified Delphi method to develop COS-UNE.

METHODS

A 5-stage approach was utilized to develop COS-UNE: stage 1, consortium development; 2, literature review to identify potential outcome measures; 3, Delphi survey to develop consensus on outcomes for inclusion; 4, Delphi survey to develop definitions; and 5, consensus meeting to finalize the COS and definitions. The study followed the Core Outcome Set-STAndards for Development (COS-STAD) recommendations.

RESULTS

The Core Outcomes in Nerve Surgery (COINS) Consortium comprised 21 participants, all neurological surgeons representing 11 countries. The final COS-UNE consisted of 22 data points/outcomes covering the domains of demographic characteristics, diagnostics, patient-reported outcomes, motor/sensory outcomes, and complications. Appropriate instruments, methods of testing, and definitions were set. The consensus minimum duration of follow-up was 6 months, with the consensus optimal timepoints for assessment identified as preoperatively and 3, 6, and 12 months postoperatively.

CONCLUSIONS

The authors identified consensus data points/outcomes and also provided definitions and specific scales to be utilized to help ensure that clinicians are consistent in their reporting across studies on UNE. This COS should serve as a minimum set of data to be collected in all future neurosurgical studies on UNE. The authors hope that clinicians evaluating ulnar neuropathy will incorporate this COS into routine practice and that future studies will consider this COS in the design phase.
