IntroductionAssessing the likelihood of engaging in high-risk sexual behavior can assist in delivering tailored educational interventions. The objective of this study was to identify the most effective algorithm and assess high-risk sexual behaviors within the last six months through the utilization of machine-learning models.MethodsThe survey conducted in the Longhua District CDC, Shenzhen, involved 2023 participants who were employees of 16 different factories. The data was collected through questionnaires administered between October 2019 and November 2019. We evaluated the model's overall predictive classification performance using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. All analyses were performed using the open-source Python version 3.9.12.ResultsAbout a quarter of the factory workers had engaged in risky sexual behavior in the past 6 months. Most of them were Han Chinese (84.53%), hukou in foreign provinces (85.12%), or rural areas (83.19%), with junior high school education (55.37%), personal monthly income between RMB3,000 (US$417.54) and RMB4,999 (US$695.76; 64.71%), and were workers (80.67%). The random forest model (RF) outperformed all other models in assessing risky sexual behavior in the past 6 months and provided acceptable performance (accuracy 78%; sensitivity 11%; specificity 98%; PPV 63%; ROC 84%).DiscussionMachine learning has aided in evaluating risky sexual behavior within the last six months. Our assessment models can be integrated into government or public health departments to guide sexual health promotion and follow-up services.

MotivationAugmented reality head-up display (AR-HUD) interface design takes on critical significance in enhancing driving safety and user experience among professional drivers. However, optimizing the above-mentioned interfaces poses challenges, innovative methods are urgently required to enhance performance and reduce cognitive load.DescriptionA novel method was proposed, combining the IVPM method with a GA to optimize AR-HUD interfaces. Leveraging machine learning, the IVPM-GA method was adopted to predict cognitive load and iteratively optimize the interface design.ResultsExperimental results confirmed the superiority of IVPM-GA over the conventional BP-GA method. Optimized AR-HUD interfaces using IVPM-GA significantly enhanced the driving performance, and user experience was enhanced since 80% of participants rated the IVPM-GA interface as visually comfortable and less distracting.ConclusionIn this study, an innovative method was presented to optimize AR-HUD interfaces by integrating IVPM with a GA. IVPM-GA effectively reduced cognitive load, enhanced driving performance, and improved user experience for professional drivers. The above-described findings stress the significance of using machine learning and optimization techniques in AR-HUD interface design, with the aim of enhancing driver safety and occupational health. The study confirmed the practical implications of machine learning optimization algorithms for designing AR-HUD interfaces with reduced cognitive load and improved occupational safety and health (OSH) for professional drivers.

ObjectiveWe report the effect of Hb E heterozygosity on HbA1c value by the Tosoh HLC-723G11.Case reportA 45 years-old Chinese woman presented with an abnormally low HbA1c level of 3.7% (3.9%–6.1%) in a health examination. Fasting blood glucose was normal. Blood routine examination and serum bilirubin were in the normal range. HbA1c was determined by Tosoh HLC-723G11. There was an abnormal peak between A1c and A0 on the chromatogram. Hemoglobin electrophoresis indicated that the Hb E zone accounted for 25.1%. The β-thalassemia-related genes (mutant type) were βE M/N, and the related gene CD26 (A &gt; G) was mutated. OGTT indicated prediabetes.ConclusionHb E heterozygosity may reduce HbA1c value with abnormal chromatograms, as determined by a Tosoh HLC G11 analyzer. The Tosoh HLC G11 analyzer can well identify Hb E variation. In this case, further blood glucose-related tests should be performed to avoid missed diagnoses. However, a large sample size is needed to confirm this conclusion.

IntroductionIt is essential to protect cancer patients from contracting COVID-19 through vaccination. A majority of cancer patients are recommended by international health authorities to take up the vaccines. COVID-19 vaccine refusal among cancer patients during the pandemic period is under-researched. This study investigated factors of vaccine refusal based on the Health Belief Model (HBM).MethodsA cross-sectional study was conducted among female breast cancer patients, male/female thyroid cancer patients, and gynecological cancer patients in Shantou, China from April to August 2022 (n = 1,115). Multinomial logistic regression analysis adjusted for socio-demographics was conducted to test factors of COVID-19. Adjusted odds ratios of the two models comparing vaccine refusal vs. “vaccine non-refusal” and vaccine refusal vs. ever-vaccination were derived and presented.ResultsOf all the participants, the prevalence of vaccine refusal, “vaccine non-refusal,” and ever-vaccination was 25.9, 22.2, and 51.8%, respectively. In both multinomial logistic regression models, significant factors of vaccine refusal included socio-demographics (age, education level, employment status, monthly household income, cancer type, duration since cancer diagnosis, current treatment status) and some vaccine-related HBM (perceived benefits, perceived barriers, cue to action, and self-efficacy). Perceived severity of COVID-19 was significant only in the vaccine refusal vs. ever-vaccination model. In neither model, perceived susceptibility to contract COVID-19 was statistically significant.ConclusionAbout ¼ of the participants expressed vaccine refusal. Interventions are warranted. Future longitudinal studies are needed to verify this study’s findings. Pilot interventions should also be launched to test effectiveness of interventions modifying the significant HBM factors found in this study.

BackgroundThe COVID-19 pandemic became a global emergency, and it is vital to understand the knowledge, attitudes, and practices of populations regarding this disease to prevent its spread.ObjectiveThe study aimed to investigate the knowledge, attitudes, and practices of the Indonesian public toward COVID-19.MethodsAn observational study was conducted in Indonesia between November 2020 and January 2021. The study employed a validated questionnaire with 391 respondents to the survey. A comparative analysis was performed to assess the mean differences in respondents’ characteristics in terms of their knowledge, attitude, and practice scores. Furthermore, regression analysis was used to investigate those factors associated with the good practice of health protocols during the COVID-19 pandemic.ResultsThe findings showed significant differences in the average knowledge scores across gender, geographical location, and educational attainment. Furthermore, significant differences in practices were identified in terms of gender and educational attainment. The findings of the study indicate that the participants demonstrated a significant awareness of COVID-19, as evidenced by their high mean knowledge score of 17.83 ± 1.74 out of a possible total score of 22 points. The results indicate that the respondents exhibited a positive attitude toward COVID-19 prevention measures, as evidenced by an attitude score of 26.95 ± 3.14 out of a possible total score of 30 points. Additionally, the mean score for good practice in health protocols aimed at reducing COVID-19 infection was found to be high (4.23 ± 0.96) at 5 points. This suggests that the study participants had already adopted effective measures to comply with the recommended health guidelines. The results of the regression analysis indicated that gender, level of education, and knowledge were statistically significant predictors for adherence to health protocols during the COVID-19 pandemic (p &lt; 0.05).ConclusionThe aforementioned results offer significant perspectives into the populace’s comprehension, disposition, and conduct regarding COVID-19 in Indonesia. These insights could potentially contribute to the formulation of efficacious measures aimed at curtailing transmission of the virus.

IntroductionBiomarkers of mental effort may help to identify subtle cognitive impairments in the absence of task performance deficits. Here, we aim to detect mental effort on a verbal task, using automated voice analysis and machine learning.MethodsAudio data from the digit span backwards task were recorded and scored with automated speech recognition using the online platform NeuroVocalixTM, yielding usable data from 2,764 healthy adults (1,022 male, 1,742 female; mean age 31.4 years). Acoustic features were aggregated across each trial and normalized within each subject. Cognitive load was dichotomized for each trial by categorizing trials at &gt;0.6 of each participants' maximum span as “high load.” Data were divided into training (60%), test (20%), and validate (20%) datasets, each containing different participants. Training and test data were used in model building and hyper-parameter tuning. Five classification models (Logistic Regression, Naive Bayes, Support Vector Machine, Random Forest, and Gradient Boosting) were trained to predict cognitive load (“high” vs. “low”) based on acoustic features. Analyses were limited to correct responses. The model was evaluated using the validation dataset, across all span lengths and within the subset of trials with a four-digit span. Classifier discriminant power was examined with Receiver Operating Curve (ROC) analysis.ResultsParticipants reached a mean span of 6.34 out of 8 items (SD = 1.38). The Gradient Boosting classifier provided the best performing model on test data (AUC = 0.98) and showed excellent discriminant power for cognitive load on the validation dataset, across all span lengths (AUC = 0.99), and for four-digit only utterances (AUC = 0.95).DiscussionA sensitive biomarker of mental effort can be derived from vocal acoustic features in remotely administered verbal cognitive tests. The use-case of this biomarker for improving sensitivity of cognitive tests to subtle pathology now needs to be examined.

IntroductionWe conducted this systematic review and meta-analysis (SRMA) to evaluate the impact of bariatric surgery on obstructive sleep apnea (OSA) as represented by the following polysomnography (PSG) parameters: apnea-hypopnea index (AHI), oxygen desaturation index (ODI), mean oxygen desaturation (mean SpO2), total sleep time spent with SpO2 &lt; 90% (T-90), and the nadir of oxygen saturation (L SpO2).MethodsA comprehensive search of the literature was conducted in Ovid MEDLINE, Embase, and Scopus databases from inception to March 31, 2023. Only articles written in English were reviewed. The analysis of all outcomes was performed using a random-effects model. We included 30 studies (two randomized controlled trials and 28 observational studies) in the final quantitative synthesis with a total of 1,369 patients.ResultsWe concluded that bariatric surgery (regardless of the type) was associated with reduction in AHI [MD 23.2 events/h (95%CI 19.7, 26.8)], ODI [MD 26.8 events/h (95%CI 21.6, 32.1)], mean SpO2 [MD−1.94% (95%CI −2.5, −1.4)], T-90 [MD 7.5min (95%CI 5.0, 10.0)], and L SpO2 [MD 9.0% (95%CI −11.8, −6.3)].ConclusionOur SRMA results are updates to previously published results and continue to support the positive impact of bariatric surgery on OSA and sleep-related hypoxia.

Objectives: The study describes the attitudes of Polish nursing personnel towards Jehovah’s Witnesses’ (JWs’) refusal to receive blood and blood products.Methods: We developed an online survey assessing nurses’ knowledge and attitudes towards JWs’ refusal of blood transfusion in a life-threatening condition. It also examined nurses’ attitudes towards ethical and legal issues associated with JWs’ refusal of blood transfusions. These questions were explored using a sample of 202 Polish nurses.Results: Nurses’ knowledge of JWs’ stance towards blood transfusions is inadequate and they tended to be ill-disposed towards JWs’ refusal of blood transfusions. Although most nurses respected adult JW patients’ autonomy and supported their right to refuse blood, in the case of JW children they are guided by paternalism. Nurses’ attitudes were affected by whether they had children, whether they declared themselves religious, their level of education and prior experience with patients who had refused a blood transfusion.Conclusion: Since most nurses felt unprepared to care for JW patients, this study reveals an urgent need to train nurses in transcultural nursing and increase nurses’ cultural competencies, and that this should be incorporated into medical curricula.
