Association of Polymorphism rs2736990 of the α-Synuclein Gene with Metabolic Syndrome Among the Population of Kazakhstan with Arterial Hypertension

Metab Syndr Relat Disord. 2024 Feb 20. doi: 10.1089/met.2023.0222. Online ahead of print.

ABSTRACT

Background: The prevalence of metabolic syndrome (MetS) in Kazakhstan reaches 40%. The presence of an association between certain genetic markers and the development of MetS will allow more accurately determining the cardiovascular risk for patients with hypertension and personalizing preventive recommendations. Methods: The purpose of the study was to investigate the presence of an associative relationship between various polymorphisms of the α-synuclein gene and the development of MetS in Kazakh people with high blood pressure. Four hundred twenty-six patients were examined [age 49.5 (interquartile range 42.5-56), men 209 (49.1%), women 217 (50.9%)]. Standard clinical and laboratory methods were used. AutoMate Express™ and OpenArray technologies were used for DNA extraction and further genotyping. Patients with MetS made up the ms+ group, those without MetS-the ms group. Results: In the examined patients, four polymorphisms of the α-synuclein gene were identified: rs356219, rs2736990, rs11931074, and rs2737029. According to the results of statistical analysis, the frequency and risk of developing MetS did not depend on different alleles and inheritance types of polymorphisms rs356219 and rs11931074. The minor allele of polymorphism rs2737029 exhibits a higher frequency in patients with arterial hypertension accompanied by MetS, although the specific model of inheritance remains to be conclusively determined. Conclusions: In carriers of the minor allele of polymorphism rs2736990, the risk of MetS increases 1.3 times, regardless of age and gender [odds ratio (95% confidence interval) = 1.36 (1.01-1.82), P < 0.05], the inheritance model is log-additive.

Denial, Attention-Seeking, and Posting Online While Intoxicated: Three Key Predictors of Collegiate Sadfishing

Cyberpsychol Behav Soc Netw. 2024 Feb 19. doi: 10.1089/cyber.2023.0268. Online ahead of print.

ABSTRACT

Sadfishing, or the exaggeration of one’s emotional state online to generate sympathy, is a maladaptive behavior that can negatively affect mental health. A better understanding of the characteristics of individuals who sadfish could inform tailored interventions to decrease sadfishing and improve quality of life. However, to date, the phenomenon of sadfishing remains understudied. Thus, the current project was designed to identify some of the key psychological and behavioral characteristics that may be associated with sadfishing. Undergraduate college students (N = 374) recruited from introductory psychology courses at a large, Hispanic-serving institution completed an anonymous online survey assessing sadfishing and other online behaviors, psychological characteristics (coping, stress, resilience, and social support), and alcohol use. Both univariate and multivariate statistical analyses were conducted. Results of the binary logistic regression analysis found that students who reported using denial as a coping strategy (p = 0.005), who endorsed the attention-seeking behaviors associated with histrionic personality disorder (p = 0.021), and who used social media while intoxicated (p = 0.017) were most likely to report sadfishing. This study furthers our knowledge of the maladaptive online behavior of sadfishing and identifies several key predictors that could become targets for tailored interventions. In particular, our results highlight the importance of coping skills training for individuals who sadfish.

Artificial Intelligence Versus Human Focus Group Rating of Facial Attractiveness

Facial Plast Surg Aesthet Med. 2024 Feb 19. doi: 10.1089/fpsam.2023.0281. Online ahead of print.

ABSTRACT

Background: Many open-access artificial intelligence (AI)-based websites that rate facial attractiveness are available, but none have been compared with human focus group outcomes. Objective: To compare human and AI-based websites scoring of facial attractiveness of adult female white faces. Methods: A 40-photograph database of AI-generated adult, white, female, expressionless, and frontal-view facial images were scored by otolaryngology residents and five AI-based facial rating websites: prettyscale.com, attractivenesstest.com, face-score.com/en, hotchat3000.com, and beautyscoretest.com. Sample t-test and bivariate correlation were performed for statistical analyses. Results: The focus group of 24 otolaryngology residents consisted of 62.5% males and 58.3% white participants. There was a strong positive correlation between average human score and average AI score for each photo (Pearson’s correlation 0.84, p < 0.01). The average human raters’ scores were significantly lower than the average AI scores (5.0 ± 1.8 vs. 6.9 ± 0.9, p < 0.01). Thirty images (75.0%) had statistically higher scores from the AI websites versus the focus group. On correlation analysis, all AI-based websites individually had scores that positively correlate with the human scores (all p < 0.05). Conclusion: AI-based websites and human focus-group scoring of facial attractiveness of adult white female faces were significantly correlated with the AI ratings biased toward higher values, encouraging their cautious utilization in future research.

Disparities in Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitors Prescription and Dispensing in the Israeli Population-A Retrospective Cohort Study

Diabetes Care. 2024 Feb 20:dc231652. doi: 10.2337/dc23-1652. Online ahead of print.

ABSTRACT

OBJECTIVE: To describe disparities in prescribing and dispensing sodium-glucose cotransporter 2 inhibitors (SGLT2i) in Israel.

RESEARCH DESIGN AND METHODS: This was a population-based retrospective cohort study of adults with type 2 diabetes eligible for SGLT2i treatment from 2017 to 2023. The primary outcome was the time between initial eligibility and the first prescription of SGLT2i.

RESULTS: Among 32,742 eligible patients, only 53% were prescribed SGLT2i. Multivariable analyses, adjusting for death as a competing risk, revealed delays in prescription were associated with older age, Arab or Bedouin ethnicity, neoplasms, acute kidney failure, falls, previous hospitalization, urinary tract infections, and dementia. Factors associated with shorter time intervals to prescription were sex (men), medium/high socioeconomic status, and residing in an intermediate or central area of Israel.

CONCLUSIONS: Disparities in drug prescription exist, even in a country with universal health coverage. Addressing these disparities requires improvements in health care systems, education, and alert systems to overcome barriers to evidence-based interventions.

Levels of Cytokines in Leptospirosis Patients with Different Serovars and rfb Locus

J Interferon Cytokine Res. 2024 Feb;44(2):80-93. doi: 10.1089/jir.2023.0091.

ABSTRACT

Leptospirosis has a wide spectrum of clinical manifestations ranging from mild to severe disease. The cytokine response is considered one of the key drivers for this varying manifestation. The different cytokine response observed in patients with leptospirosis could be due to the variation of infecting serovars. Since the rfb locus codes for the lipopolysaccharide synthesis of the bacterial cell wall, which also determines the serovar, this locus may play a role in driving a specific cytokine response in the host. We investigated 12 commonly used cytokine profiles in serum samples of culture, microscopic agglutination test (MAT), or polymerase chain reaction (PCR)-positive patients with leptospirosis. The sequences of the rfb locus in culture-positive samples were generated from whole genome sequencing and serovar status was drawn from original data published. Isolated cultures were subjected to whole genome sequencing using the PacBio RS II system, and the resulting data were used to determine the species. The recovered genomic data were annotated with the Rapid Annotation using Subsystem Technology (RAST) subsystem, and the rfb locus was extracted. The cytokine analysis was carried out using the Qiagen human ELISA kit. Eighteen samples were found to be positive by culture, while the other 7 samples were positive by PCR or MAT. Infections from Leptospira interrogans serovar Autumnalis (5), Pyrogens (3), Icterohaemorrhagiae (1) Leptospira borgpetersenii (all 7 samples clustered in same clonal group with serovar status not determined), Leptospira weilii (1 with serovar status not determined), and Leptospira kirschneri serovar Grippotyphosa (1) were included in the analysis. Three patients [infected with Leptospira interrogansserovar Autumnalis (2) and Pyrogens (1)] and 2 MAT-positive patients (highest titer against serovar Bratislava of L.interrognas) were reported to have severe clinical manifestations, while the rest had mild to moderate symptoms. Although the serum cytokine concentration of patients with severe clinical manifestation was comparatively higher, a statistically significant difference was observed only for interleukin (IL)-1β (P < 0.05). IL-10/tumor necrosis factor-alpha (TNF-α) ratio was high in patients with severe complications. In general, patients infected with L. interrogans showed higher concentration of cytokines compared to L. borgpetersenii.

Health Care Students’ Perceptions of Bias During Their Clinical Training and Insights on Mitigating It

J Physician Assist Educ. 2024 Mar 1;35(1):88-93. doi: 10.1097/JPA.0000000000000550. Epub 2023 Sep 1.

ABSTRACT

PURPOSE: To understand health care students’ perception of implicit bias and examine their insights to create a bias-free training environment.

METHODS: Clinical phase students from one university’s 4 health care programs participated in this study. Students were surveyed regarding their knowledge of implicit bias and perception of their experiences in the clinical learning environment.

RESULTS: The response rate was 50.9%, N = 161. In total, 52.6% reported having prior training on implicit bias, and 55% self-reported that they had personally observed preceptors who exhibited an implicit bias toward patients based on race, ethnicity, or other qualities. There was no statistically significant relationship between those with prior training on implicit bias and being able to identify implicit bias exhibited by preceptors. Participants also expressed their unwillingness to report an incident unless it is confidential due to fear of retribution.

CONCLUSION: This study found that health care students from one university’s 4 health care programs perceived implicit bias in their clinical learning environment, which they believe could be improved by taking intentional steps. Some suggestions provided were “Safe space to report and openly discuss bias,” “Education/training on implicit bias,” “Time for self-reflection,” and “Hiring process that evaluates/trains against implicit bias.” The implication of our study is to create a bias-free training environment that will help interrupt the propagation of biases contributing to health disparity. Further research should examine a national population and identify interventional methods and outcomes in multiple health care disciplines.

Work-related mental health problems in Switzerland

J Occup Environ Med. 2024 Feb 20. doi: 10.1097/JOM.0000000000003076. Online ahead of print.

ABSTRACT

OBJECTIVE: The study identifies work-related risk factors that are relevant to mental health and quantifies their influence. This allows estimation of risk levels for individual workplaces and of the proportion of occupational causation in the emergence of mental health problems.

METHODS: Swiss Health Survey data, containing information on several potential risk factors and health indicators that cover aspects of mental health, were used in multiple multivariate logistic regression analyses.

RESULTS: Stress was the predominant risk factor, followed by exposure to violence, unergonomic work processes, and work that conflicted with family life. Hotel and restaurant industries and health and social services had high exposure to risk factors. One out of 20 workplaces was deemed high-risk based on an odds ratio > 4.

CONCLUSIONS: Up to one-third of mental health problems within the active workforce may have highly predominant occupational causation.

Retinal-glia ischemia and inflammation induced by chronic stress: The SABPA study

Brain Behav Immun Health. 2019 Dec 17;2:100027. doi: 10.1016/j.bbih.2019.100027. eCollection 2020 Feb.

ABSTRACT

BACKGROUND: Psychobiological processes linking stress and vascular diseases remain poorly understood. The retina and the brain share a common embryonic-diencephalon origin and blood-barrier physiology e.g. ongoing ischemia facilitates S100B release with astrocytic activity and glial-fibrillary-acidic-protein expression (GFAP). However, GFAP decreases revealed astrocyte pathology in the prefrontal cortex of depression/suicide cases; and might be a key mechanism in stress – disease pathways.

METHODS: A chronic emotional stress phenotype independent of age, ethnicity or sex was used to stratify the current prospective cohort (N ​= ​359; aged 46 ​± ​9 years) into Stress (N ​= ​236) and no-Stress groups (N ​= ​123). Prospective data for glia ischemia risk markers were obtained, including 24 ​h BP, fasting S100B, GFAP, HbA1C and tumor-necrosis-factor-α (TNF-α). At 3-yr follow-up: diastolic-ocular-perfusion-pressure (indicating hypo-perfusion risk) was measured and retinal vessel calibers were quantified from digital images in the mydriatic eye.

RESULTS: Higher hypertension (75% vs. 16%), diabetes (13% vs. 0%) and retinopathy (57% vs. 45%) prevalence was observed in Stress compared to no-Stress individuals. Stressed individuals had consistently raised S100B, TNF-α, HbA1C and higher diastolic-ocular-perfusion-pressure, but decreases in GFAP and GFAP:S100B. Furthermore stroke risk markers, arterial narrowing and venous widening were associated with consistently raised S100B, GFAP:S100B (p ​= ​0.060), TNF-α and higher diastolic-ocular-perfusion-pressure [Adj. R2 0.39-0.41, p ​≤ ​0.05]. No retinal-glia associations were evident in the no-Stress group.

CONCLUSIONS: Retinal-glia ischemia and inflammation was induced by chronic stress. Persistent higher inflammation and S100B with GFAP decreases further reflected stress-induced astrocyte pathology in the human retina. It is recommended to increase awareness on chronic stress and susceptibility for brain ischemia.

Use of Cancer-Directed therapy at the end of life among adolescents and young adults

J Natl Cancer Inst. 2024 Feb 20:djae038. doi: 10.1093/jnci/djae038. Online ahead of print.

ABSTRACT

BACKGROUND: Adolescents and young adults (AYAs) frequently receive chemotherapy near death. We know less about use of targeted agents and immunotherapy or trends over time.

METHODS: We conducted a retrospective cohort study of 1,836 AYAs with cancer who died between 2009-2019 after receiving care at one of three sites (Dana-Farber Cancer Institute, Kaiser Permanente Northern California, and Kaiser Permanente Southern California). We reviewed electronic health data and medical records to examine use of cancer-directed therapy in the last 90 days of life, including chemotherapy, targeted therapy, immunotherapy, and investigational drugs.

RESULTS: Over the study period, 35% of AYAs received chemotherapy in the last 90 days of life; 24% received targeted therapy, 7% immunotherapy, and 5% investigational drugs. Fifty-six percent received at least one form of systemic cancer-directed therapy in the last 90 days of life. After adjustment for patient sex, race, ethnicity, age, site of care, diagnosis, and years from diagnosis to death, the proportion of AYAs receiving targeted therapy (odds ratio (OR) 1.05 per year of death, 95% confidence interval (CI) 1.02-1.10, P = .006), immunotherapy (OR 1.27, 95%CI 1.18-1.38, P<.0001), and any cancer-directed therapy (OR1.04, 95%CI 1.01-1.08, P=.01) in the last 90 days of life increased over time.

CONCLUSIONS: More than half of AYAs receive cancer therapy in the last 90 days of life, and use of novel agents such as targeted therapy and immunotherapy are increasing over time. While some AYAs may wish to continue cancer therapy while living with advanced disease, efforts are needed to ensure that use of cancer-directed therapy meets preferences of AYAs approaching death.

imputomics: web server and R package for missing values imputation in metabolomics data

Bioinformatics. 2024 Feb 20:btae098. doi: 10.1093/bioinformatics/btae098. Online ahead of print.

ABSTRACT

MOTIVATION: Missing values are commonly observed in metabolomics data from mass spectrometry (MS). Imputing them is crucial because it assures data completeness, increases the statistical power of analyses, prevents inaccurate results, and improves the quality of exploratory analysis, statistical modeling, and machine learning. Numerous Missing Value Imputation Algorithms (MVIAs) employ heuristics or statistical models to replace missing information with estimates. In the context of metabolomics data, we identified 52 MVIAs implemented across 70 R functions. Nevertheless, the usage of those 52 established methods poses challenges due to package dependency issues, lack of documentation and their instability.

RESULTS: Our R package, imputomics, provides a convenient wrapper around 41 (plus random imputation as a baseline model) out of 52 MVIAs in the form of a command-line tool and a web application. In addition, we propose a novel functionality for selecting MVIAs recommended for metabolomics data with the best performance or execution time.

AVAILABILITY: imputomics is freely available as an R package (github.com/BioGenies/imputomics) and a Shiny web application (biogenies.info/imputomics-ws). The documentation is available at biogenies.info/imputomics.

SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.
