Authors: Almansour Bashar Yaser , Elkrghli Sabri , Almansour Ammar Yaser 
Published: July 2023

Purpose: This study aims to examine the impact of behavioral finance factors on the investment decisions of Gulf investors in the cryptocurrency market.

Theoretical Framework: The study is based on the behavioral finance theory, which highlights the role of emotions and cognitive biases in shaping investment decisions. It examines the investment behavior and decision-making of Gulf investors in the cryptocurrency market using a comprehensive set of factors, including herding, heuristics, prospect, market, familiarity bias, and self-attribution bias.

Design/Methodology/Approach: Primary data is collected through a survey-based approach using a 23-question distributed at the country level covering the United Arab Emirates, Kuwait, Qatar, and Saudi Arabia. The study analyzes the data collected using statistical methods to study the impact of behavioral finance factors on the investment decisions.

Findings: The results show that herding and heuristics strongly influence investment decisions in the cryptocurrency market among Gulf investors. The prospect factor positively affects investment decision-making in KSA and Qatar but not in UAE and Kuwait. The market factor is a significant determinant of investment behavior, and investors in UAE and Qatar are more cautious and risk-averse compared to KSA and Kuwait. The familiarity bias factor has different effects on investment decision making in KSA and UAE.

Research, Practical & Social Implications: This study offers valuable insights into how behavioral finance factors impact investment decisions in the cryptocurrency market. These findings can be useful to investors and financial institutions in developing investment strategies that take into account the cognitive and emotional biases of investors.

Originality/Value: The study uses a comprehensive set of behavioral finance factors and includes respondents from four Gulf countries. Therefore, the study contributes to the existing literature by providing unique insights into the investment behavior and decision-making of Gulf investors in the cryptocurrency market.

Published: July 2023

In the present study waste aluminium cans were recycled and converted to produce alumina catalyst. These cans contain more than 98% aluminum oxide in their structure and were successfully synthesized to produce nano sized gamma alumina under mild conditions. A comprehensive study was carried out in order to examine the effect of several important parameters on maximum yield of alumina that can be produced. These parameters were reactants mole ratios (1.5, 1.5, 2, 3, 4 and 5), sodium hydroxide concentrations (10, 20, 30, 40, 50 and 55%) and weights of aluminum cans (2, 4, 6, 8 and 10 g). The compositions of alumina solution were determined by Atomic absorption spectroscopy (AAS); and maximum yield of alumina solution was 96.3% obtained at 2 mole ratios of reactants, 40% sodium hydroxide concentrations and 10g of aluminum cans respectively. Gamma alumina was acquired by hydrothermal treatment of alumina solution at pH 7 and calcination temperature of 550 ºC. The prepared catalyst was characterized by X-ray diffraction (XRD), N2 adsorption/ desorption isotherms, X-ray fluorescence (XRF) and atomic force microscopy (AFM). Results showed good crystallinity of alumina as described by XRD patterns, with surface area of 311.149 m2/g, 0.36 cm3/g pore volume, 5.248 nm pore size and particle size of 68.56 nm respectively.

Language and culture in health communication in an emergency context: do health practitioners and patients talk differently about uncertainty and risk?
Authors: Nissen Vanda , Meuter Renata F. I. 
Published: July 2023

ObjectiveTo explore how expressions of uncertainty are used and understood by patients and their health practitioners (HPs) in language-concordant vs. language-discordant consultations and to invoke CAT to identify the use of communication strategies, with a focus on HPs.MethodsThis qualitative study encompassed 15 transcribed video and audio recordings of medical consultations between monolingual and bilingual patients and HPs captured in an Australian Emergency Department (ED). HPs and patients also completed a Language Background Questionnaire (LBQ). The main outcome measures included the number and type of expressions of risk and uncertainty used by patients and HPs and the strategies used by HPs to accommodate their patients' conversational needs.ResultsA total of 15 representative conversations were analyzed, involving two bilingual and two monolingual HPs and 14 patients (of whom five were bilingual). All conversations contained epistemic expressions (e.g., probably), which were used more frequently by patients and more often by bilingual patients. HPs accommodated the patients effectively overall, but some bilingual patients showed difficulties in their understanding.ConclusionAll interlocutors expressed uncertainty to varying degrees. The greater use of uncertainty expressions by (bilingual) patients suggests that HPs could increase their communicative effectiveness by attending specifically to their patients' uncertainty talk. Such talk may reflect a need for reassurance. For culturally and linguistically diverse patients, it may reflect issues with comprehension.

BackgroundDespite the importance of attaining optimal lipid levels from a young age to secure long-term cardiovascular health, the detailed impact of non-optimal lipid levels in young adults on coronary artery calcification (CAC) is not fully explored. We sought to investigate the risk of CAC progression as per lipid profiles and to demonstrate lipid optimality in young adults.MethodsFrom the KOrea Initiative on Coronary Artery calcification (KOICA) registry that was established in six large volume healthcare centers in Korea, 2,940 statin-naïve participants aged 20–45 years who underwent serial coronary calcium scans for routine health check-ups between 2002 and 2017 were included. The study outcome was CAC progression, which was assessed by the square root method. The risk of CAC progression was analyzed according to the lipid optimality and each lipid parameter.ResultsIn this retrospective cohort (mean age, 41.3 years; men 82.4%), 477 participants (16.2%) had an optimal lipid profile, defined as triglycerides &lt;150 mg/dl, LDL cholesterol &lt;100 mg/dl, and HDL cholesterol &gt;60 mg/dl. During follow-up (median, 39.7 months), CAC progression was observed in 434 participants (14.8%), and more frequent in the non-optimal lipid group (16.5% vs. 5.7%; p &lt; 0.001). Non-optimal lipids independently increased the risk of CAC progression [adjusted hazard ratio (aHR), 1.97; p = 0.025], in a dose-dependent manner. Even in relatively low-risk participants with an initial calcium score of zero (aHR, 2.13; p = 0.014), in their 20 s or 30 s (aHR 2.15; p = 0.041), and without other risk factors (aHR 1.45; p = 0.038), similar results were demonstrable. High triglycerides had the greatest impact on CAC progression in this young adult population.ConclusionNon-optimal lipid levels were significantly associated with the risk of CAC progression in young adults, even at low-risk. Screening and intervention for non-optimal lipid levels, particularly triglycerides, from an early age might be of clinical value.

Published: July 2023

BackgroundPoor sleep quality is associated with different physical and mental health diseases. It is proposed that increased hypothalamic-pituitary-adrenal axis activity is a potential contributor affecting sleep pattern and quality. We aimed to analyze the relationship between subjective sleep quality indicators and hair glucocorticoid levels among relatively healthy perimenopausal and postmenopausal women.MethodsA total of 145 women aged 50–64 y.o. were enrolled in the cross-sectional pilot study. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index, while stress level was measured using the Perceived Stress Scale. Hair cortisol and cortisone levels were determined by ultra-high-performance liquid chromatography-tandem mass spectrometry.ResultsStatistically significant positive relationship was found between hair cortisol concentration and Pittsburgh sleep quality index score. Similarly, statistically significant positive associations were observed between hair total glucocorticoid level and Pittsburgh sleep quality index, sleep disturbance, and Perceived Stress Scale scores. Subjects with prolonged sleep latency had significantly higher hair cortisol and total hair glucocorticoid concentrations compared with individuals whose sleep latency is not disturbed. Additionally, Chi-squared test indicated that lower hair cortisol concentration was significantly related to better sleep efficiency.ConclusionIncreased hair glucocorticoid (cortisol, cortisone) levels were found to be related with worse sleep quality measured by Pittsburgh sleep quality index score.

Authors: Liu Huawei , Sun Qingyan , Bi Wenting , Mu Xiaodan , Li Yongfeng , Hu Min 
Published: July 2023

Background: Effects of hypertension, type 2 diabetes and obesity on Bell’s palsy risk remains unclear. The aim of the study was to explore whether hypertension and these metabolic disorders promoted Bell’s palsy at the genetic level.Methods: Genetic variants from genome-wide association studies for hypertension, type 2 diabetes, body mass index and several lipid metabolites were adopted as instrumental variables. Two-sample Mendelian randomization including IVW and MR-Egger was used to measure the genetic relationship between the exposures and Bell’s palsy. Sensitivity analyses (i.e., Cochran’s Q test, MR-Egger intercept test, “leave-one-SNP-out” analysis and funnel plot) were carried out to assess heterogeneity and horizontal pleiotropy. All statistical analyses were performed using R software.Results: Hypertension was significantly associated with the increased risk of Bell’s palsy (IVW: OR = 2.291, 95%CI = 1.025–5.122, p = 0.043; MR-Egger: OR = 16.445, 95%CI = 1.377–196.414, p = 0.029). Increased level of LDL cholesterol might upexpectedly decrease the risk of the disease (IVW: OR = 0.805, 95%CI = 0.649–0.998, p = 0.048; MR-Egger: OR = 0.784, 95%CI = 0.573–1.074, p = 0.132). In addition, type 2 diabetes, body mass index and other lipid metabolites were not related to the risk of Bell’s palsy. No heterogeneity and horizontal pleiotropy had been found.Conclusion: Hypertension might be a risk factor for Bell’s palsy at the genetic level, and LDL cholesterol might reduce the risk of the disease. These findings (especially for LDL cholesterol) need to be validated by further studies.

PurposeTo explore the etiology and choroidal thickness (ChT) pattern in children with early-onset high myopia (eoHM).MethodsSixty children with eoHM and 20 healthy controls were enrolled in this study between January 2019 and December 2021. All children underwent comprehensive ophthalmologic examinations including swept-source optical coherence tomography. ChT was measured in the subfoveal region and at 1000 μm and 2,500 μm nasal, temporal, superior, and inferior to the fovea.ResultsOverall, 120 eyes of 60 children with eoHM were examined (mean spherical equivalent, −8.88 ± 3.05 D; mean axial length, 26.07 ± 1.59 mm). Simple high myopia (SHM), familial exudative vitreoretinopathy (FEVR), and Stickler syndrome (STL) were the most frequent etiologies of eoHM and were included in further ChT analysis. Adjusted the effect of SE, multivariate regression analysis showed that children with SHM had thinnest ChT at N2500 and I2500 among the subgroups (p = 0.039, p = 0.013). FEVR group showed thinner ChT at T2500 (p = 0.023), while STL patients exhibited thin ChT at all locations.ConclusionThis study revealed that SHM, STL and FEVR was the most frequent etiology, and showed a distinctive pattern of ChT. Asymmetric nasal ChT thinning is a distinctive biomarker for SHM, asymmetric temporal ChT thinning might serve as a biomarker for FEVR, and symmetric diffuse thinning is more common in STL. These ChT patterns may provide a convenient, fast, and noninvasive strategy to differentiate the potential etiology of eoHM.

Authors: Sattoe Jane N. T. , Hilberink Sander R. 
Published: July 2023

IntroductionAging with a childhood-onset disability, such as cerebral palsy (CP), spina bifida (SB), and muscular diseases (MD), comes along with significant impairments and comorbidities. Despite the increasing evidence an overall picture is lacking. This study aimed to review the literature about adults with CP/SB/MD and impairments and comorbidities to perform a meta-analysis.Materials and methodsEmbase, PubMed, Cinahl, and Google Scholar were searched (2000–2020). Search terms included adults with one of the aforementioned disabilities combined with impairments and comorbidities. If specific impairments or comorbidities were reported by at least four studies, these were included in the study. Pooled prevalence (95% Confidence Interval) of impairments/comorbidities were calculated.ResultsThe search yielded 7,054 studies of which 95 were included in the meta-analysis (64 CP, 31 SB, 0 MD). In total estimates were calculated for 26 (CP) and 11 (SB) outcomes. In adults with CP, pain [56.4% (95%CI 48.8–63.8)], deformities [44.2% (95%CI 12.9–78.4)], intellectual disability [37.2% (95%CI 26.7–48.3)], and fatigue [36.9% (95%CI 24.6–50.1)] were most prevalent; renal disease [3.0% (95%CI 2.1–4.2)] and stroke/rheumatic diseases {4.8% (95%CI 3.4–6.5; 4.8% (95%CI 1.5–9.9)] respectively} were least prevalent. For adults with SB, bladder incontinence [60.0% (95%CI 50.5–69.2)], bowel incontinence [49.2% (95%CI 34.5–64.0)], pain [44.1% (95%CI 27.4–61.5)], and sleeping problems [30.3% (95%CI 4.7–65.8)] were most prevalent; diabetes [4.8% (95%CI 2.8–7.3)] and renal disease [8.7% (95%CI 2.0–19.9)] were least prevalent. The included studies showed large heterogeneity.ConclusionsMore research is needed to study health issues in adults with MD. Adults with CP or SB deal with a variety of health issues. More attention for the mental health of these adults is needed. There also is a need for accessible and adequate screening, preventive measures and clinical follow-up.

Published: July 2023

Background and purposePrevious studies have described an association between pulse pressure (PP) level and mortality in stroke patients. Evidence of associations between PP level and the risk of mortality remains unknown in non-traumatic subarachnoid hemorrhage (SAH) patients. We aimed to explore the relationship between the baseline PP level and hospital mortality.MethodsThis cohort study of 693 non-traumatic SAH adults used Medical Information Mart for Intensive Care (MIMIC-IV) data from 2008–2019 admissions to Intensive Care Unit (ICU). PP level was calculated as the first value after admission to the ICU. The endpoint of the study was in-hospital mortality. Cox proportional hazards models were utilized to analyze the association between baseline PP level and hospital mortality. Restricted Cubic Splines (RCS) analysis was utilized to determine the relationship curve between hospital mortality and PP level and examine the threshold saturation effect. We further applied Kaplan–Meier survival curve analysis to examine the consistency of these correlations. The interaction test was used to identify subgroups with differences.ResultsThe mean age of the study population was 58.8 ± 14.6 years, and 304 (43.9%) of participants were female. When baseline PP level was assessed in quartiles, compared to the reference group (Q1 ≤ 56 mmHg), the adjusted hazard ratio (HR) in Q2 (57–68 mmHg), Q3(69–82 mmHg), Q4 (≥83 mmHg) were 0.55 (95% CI: 0.33–0.93, p = 0.026), 0.99 (95% CI, 0.62–1.59, p = 0.966), and 0.99 (95% CI: 0.62–1.59, p = 0.954), respectively. In the threshold analysis, for every 5 mmHg increase in PP level, there was an 18.2% decrease in hospital mortality (adjusted HR, 0.818; 95% CI, 0.738–0.907; p = 0.0001) in those with PP level less than 60 mmHg, and a 7.7% increase in hospital mortality (adjusted HR, 1.077; 95% CI, 1.018–1.139; p = 0.0096) in those with PP level was 60 mmHg or higher.ConclusionFor patients with non-traumatic SAH, the association between baseline PP and risk of hospital mortality was non-linear, with an inflection point at 60 mmHg and a minimal risk at 57 to 68 mmHg (Q2) of baseline PP level.

BackgroundPsychedelic drug experiences are shaped by current-moment contextual factors, commonly categorized as internal (set) and external (setting). Potential influences of past environments, however, have received little attention.AimsTo investigate how previous environmental stimuli shaped the experiences of patients receiving ketamine for treatment-resistant depression (TRD), and develop the concept of “imprinting” to account for such time-lagged effects across diverse hallucinogenic drugs.MethodsRecordings of treatment sessions and phenomenological interviews from 26 participants of a clinical trial investigating serial intravenous ketamine infusions for TRD, conducted from January 2021 to August 2022, were retrospectively reviewed. A broad literature search was undertaken to identify potentially underrecognized examples of imprinting with both serotonergic and atypical psychedelics, as well as analogous cognitive processes and neural mechanisms.ResultsIn naturalistic single-subject experiments of a 28-year-old female and a 34-year-old male, subjective ketamine experiences were significantly altered by varying exposures to particular forms of digital media in the days preceding treatments. Higher levels of media exposure reduced the mystical/emotional qualities of subsequent psychedelic ketamine experiences, overpowering standard intention-setting practices and altering therapeutic outcomes. Qualitative data from 24 additional patients yielded eight further spontaneous reports of past environmental exposures manifesting as visual hallucinations during ketamine experiences. We identified similar examples of imprinting with diverse psychoactive drugs in past publications, including in the first-ever report of ketamine in human subjects, as well as analogous processes known to underly dreaming.Conclusions/interpretationPast environmental exposures can significantly influence the phenomenology and therapeutic outcomes of psychedelic experiences, yet are underrecognized and understudied. To facilitate future research, we propose expanding the contextual model of psychedelic drug actions to incorporate imprinting, a novel concept that may aid clinicians, patients, and researchers to better understand psychedelic drug effects.Clinical trial registrationClinicalTrials.gov, identifier NCT04701866.
