Background and ObjectiveWe are exposed to solar radiation from early childhood, so learning different photoprotection strategies is fundamental. As a primary prevention tool, knowledge of the solar ultraviolet radiation to which we are exposed is fundamental. There are devices based on the color change of photochromic substances when exposed to UV radiation which are widely used as a tool for children’s play. The aim was to assess both quantitatively and qualitatively the effectiveness of the use of these devices under different conditions of simulated sun exposure.Materials and MethodsTen commercial UV-indicating photochromic devices plus three pure photochromic substances were used. Photochromic devices belong to the spirooxazine family of molecules. They were exposed to different rates of UV radiation under a solar UV-visible simulator, and their velocity, degree of response, and color reversal time were analyzed both visually and objectively using a colorimeter based on three-dimensional CIE L*a*b* color space values. Activation response was also evaluated under different UV high-energy visible light wavelengths using different cut-off filters. Finally, the devices were exposed under high UV irradiance (corresponding to UVI of 10) and interposing sunscreens of different sun protection factors in order to evaluate their potentials as indicators for sunscreen re-application.ResultsAll the devices and pure substances offered color change almost immediately under simulated solar radiation. From very low irradiances (UVI &gt;3), they saturated color, and it was not possible to observe and measure color change. The time to color reversal took longer than activation (from 60 s to obtain initial values). When devices were exposed to a UVI of 10 with topical sunscreen overlay, color was observed after 1 min irradiation even under SPF of 50+ sunscreen. Photochromic devices were activated under both UVA and high energy visible light.ConclusionUV radiation indicators using photochromic substances which, although possible awareness-raising elements, are of limited use as indicators of UV radiation intensity and dosimetry. They are useful elements for detecting the presence/absence of UV radiation and do not distinguish between different UV radiation spectral bands. Moreover, their incorporation as photoprotective elements used by minors could lead to exposures that are not objectively controlled.

Introduction: Hepatic cystic echinococcosis (HCE) is a widely seen parasitic infection. Biological activity is crucial for treatment planning. This work aims to explore the potential applications of a deep learning radiomics (DLR) model, based on CT images, in predicting the biological activity grading of hepatic cystic echinococcosis.Methods: A retrospective analysis of 160 patients with hepatic echinococcosis was performed (127 and 33 in training and validation sets). Volume of interests (VOIs) were drawn, and radiomics features and deep neural network features were extracted. Feature selection was performed on the training set, and radiomics score (Rad Score) and deep learning score (Deep Score) were calculated. Seven diagnostics models (based on logistic regression algorithm) for the biological activity grading were constructed using the selected radiomics features and two deep model features respectively. All models were evaluated using the receiver operating characteristic curve, and the area under the curve (AUC) was calculated. A nomogram was constructed using the combined model, and its calibration, discriminatory ability, and clinical utility were assessed.Results: 12, 6 and 10 optimal radiomics features, deep learning features were selected from two deep learning network (DLN) features, respectively. For biological activity grading of hepatic cystic echinococcosis, the combined model demonstrated strong diagnostic performance, with an AUC value of 0.888 (95% CI: 0.837–0.936) in the training set and 0.876 (0.761–0.964) in the validation set. The clinical decision analysis curve indicated promising results, while the calibration curve revealed that the nomogram’s prediction result was highly compatible with the actual result.Conclusion: The DLR model can be used for predicting the biological activity grading of hepatic echinococcosis.

IntroductionTo evaluate the preoperative health-related quality of life (HRQoL) and influencing factors of HRQoL in patients undergoing thyroidectomy based on patient-reported outcomes.Materials and methodsPatients who were diagnosed and treated in Sichuan Cancer Hospital from February 2022 to December 2022 and were scheduled to undergo thyroidectomy were included. Each participant completed the basic information questionnaire and patient-reported outcome assessment scales before surgery. HRQoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30), the Thyroid Cancer-Specific Quality of Life (THYCA-QoL), and the Hamilton Anxiety Scale (HAMA). The Wilcoxon rank sum test or the Kruskal-Wallis test was used to analyze the association between patient characteristics and HRQoL, and the variables with statistical significance were included in multiple linear regression analysis.Results450 patients were included in the study. According to the analysis of the THYCA-QoL scores, the psychological subscale was the most complained about. Anxiety was the most common symptom of the HAMA. Factors associated with worse general QoL on the EORTC QLQ-C30 included nondiagnostic/unsatisfactory fine-needle aspiration (FNA) result. Planned lateral neck dissection and nondiagnostic/unsatisfactory FNA result were influential factors for preoperative anxiety. Males and longer sleep duration were associated with better thyroid cancer-specific QoL, better general QoL, and less anxiety.ConclusionThe preoperative HRQoL of patients undergoing thyroidectomy was generally good. Females, insufficient sleep duration, planned lateral neck dissection, and nondiagnostic/unsatisfactory FNA result were associated with worse preoperative HRQoL.

BackgroundSuicide among college students is a significant public health concern in China. While suicidal ideation serves as a crucial predictor of subsequent suicidal plans and behaviors, it is important to recognize that most instances of suicidal ideation may only be fleeting thoughts that do not progress to an actual plan. Therefore, it is imperative to identify the factors associated with the transition from suicidal ideation to a concrete plan. Consequently, this study aims to investigate whether certain frequently cited factors can differentiate individuals who have formulated a specific suicidal plan from those who have experienced suicidal thoughts without planning, based on data obtained through a cross-sectional survey.Materials and methodsThis survey was conducted as part of routine mental health assessments among second-year college students in October 2023. Data from a total of 4,858 second-year college students were utilized for the final analyses. Two survey questions were employed to identify past-year suicidal ideation and past-year suicidal plan. All participants were required to complete various assessments, including the Chinese version of Depression Anxiety Stress Scale 21 items (DASS-21), the Chinese version of Gratitude Questionnaire-six items (GQ-6), the Chinese version of Meaning in Life Questionnaire (MLQ), and the Chinese version of State Hope Scale (SHS).ResultsAmong 4,858 participants, a total of 134 individuals (2.8%) were confirmed to have experienced past-year suicidal ideation. Out of these, 53 (1.1% overall) reported having a past-year suicidal plan, accounting for approximately 39.6% of those with suicidal ideation. Logistic regression analyses revealed that while most potential variables differentiated between students with and without suicidal ideation, only two factors stood out in distinguishing individuals with a suicidal plan from those who had not made such plans despite experiencing suicidal thoughts—presence of stress (OR=2.49, 95% CI: 1.04–5.96) and lower scores of hope agency (OR=0.84, 95% CI: 0.72–0.98).ConclusionThese findings suggest that the stress may contribute to susceptibility for transitioning from mere thoughts to actual planning regarding suicide; conversely, hope agency appears to offer protection against this transition process. Therefore, we advocate for targeted interventions aimed at fostering hope among individuals who have encountered adverse and stressful life events.

BackgroundOver the past decade migration to Italy has increased significantly for various reasons including armed conflicts. Generally, the migration process is exposed to different risk factors during different periods of migration, which can compromise well-being and promote the onset or exacerbation of mental disorders. A community with resources and the perception of one’s community as resilient can be important protective factor in the context of migration.PurposeThis study aims to understand which variables in migration predict an increase in perceived community resilience and to understand the role of community resilience in the relationship between mental disorders and subjective well-being in a sample of 100 adult migrants at the first consultation interview in the ambulatories of Psychiatry Unit.MethodsAfter defining the inclusion and exclusion criteria, migrants were asked to fill out self-report questionnaires to collect socio-demographic data and to assess perception of mental disorders, perceived community resilience and perception of subjective well-being. Descriptive analysis, simple regression, and moderation analyses were conducted to test the hypotheses.ResultsThe results show that the variable meaning attributed to the community with reference to the host community, migration with someone, and longer duration of stay in Italy contribute to increased perceptions of community resilience. In addition, a direct negative effect of mental disorders on subjective well-being and the moderating role of community resilience in relationship between mental disorders and subjective well-being have been demonstrated.ConclusionsThis result underscores the importance of perceived community resilience in mitigating the negative effects of mental disorders on subjective well-being. Perceiving one’s community as more resilient seems to protect against the impact of mental disorders on subjective well-being. Our results support an ecological model of migrants’ mental health that values the community and its resources in coping with mental disorders in the context of migration.

Published: August 2024

IntroductionThis study explores the influence of artificial intelligence (A.I.) applications on the job performance of healthcare providers, based on data from standardised-trained residents in the First People’s Hospital of Yunnan Province in China.MethodsThe ordinary least squares model is employed to examine the relationship between A.I. applications and job performance. To address potential endogeneity and missing variables, we utilise the propensity score matching method and alternative regression models.ResultsThe findings indicate that the job performance of standardised-trained residents positively correlates with A.I. applications. This relationship remains robust after addressing endogenous and missing variables. Further discussion reveals that patients’ support mediates the relationship between A.I. and job performance. Under identical conditions, the job performance of female residents empowered by A.I. is found to be significantly better than that of their male counterparts. Conversely, no heterogeneity is observed regarding the impact of A.I. on the job performance of medical practitioners and clinical medical technicians.DiscussionThis study underscores the positive role of A.I. applications in enhancing the job performance of standardised-trained residents. The results highlight the mediating role of patient support and suggest gender-based differences in the efficacy of A.I. empowerment.

BackgroundHuman papillomavirus (HPV) is a main pathogenic factor for cervical carcinoma. The prevalence and genotypes distribution of HPV vary in different regions. Thus, our study aimed to investigate the epidemiology of HPV in Huizhou, China.MethodsHPV tests were detected in 5,325 female outpatients, we focused on the overall HPV prevalence, genotypes distribution, and the correlation of HPV genotypes with cervical cytology.ResultsThe overall HPV prevalence was 27.53%, HPV52, HPV58, HPV39, HPV16 and HPV51 were predominant genotypes with single infection rate of 70.80%. HPV infection rate showed a U-shaped age distribution, statistical differences were observed among 5 age groups (χ2 = 50.497, p &lt; 0.01), and the higher positive rate was aged under 30 (34.42%) and above 60 (34.74%). Among high-risk HPV (hrHPV) infections, 60.69% involved NILM, 0.99% HSIL. The degrees of cervical lesions in multiple hrHPV infections were worse than those in single infection (p &lt; 0.01).ConclusionThe HPV infection rate is high in Huizhou, Guangdong, single infection was predominant. HPV infection presented with a U-shaped age distribution. Multiple hrHPV infection was worrying since it may aggravate cervical lesions. Women should pay more attention to HPV detection and choose a more appropriate HPV vaccine according to local HPV type distribution.

The motoric cognitive risk syndrome (MCR) is a syndrome characterized by subjective memory complaints and slow walking speeds that can identify older adults at increased risk for developing Alzheimer’s disease or a related dementia (ADRD). To date, the feasibility of community-based physical activity (PA) programs for improving outcomes in MCR have yet to be examined. To address this knowledge gap, we conducted a translational randomized controlled trial (RCT) comparing 24-weeks of PA to a healthy aging education (HE) control intervention delivered within the infrastructure of an urban senior center in Greater Boston (clincaltrials.gov identifier: NCT03750682). An existing senior center employee was trained to administer the multimodal group-based PA program that included moderate-intensity aerobic walking, strength, flexibility and balance training. A total of 79 older adults attended the senior center for a screening visit, of whom 29 met the MCR criteria and 25 were randomized to PA or HE (mean age: 74.4 ± 7 years; BMI: 32.4 ± 7 kg/m2; 85% female; 3MSE score: 92.4 ± 7; gait speed: 0.52 ± 0.1 m/s; SPPB score 4.8 ± 1.9). Due to the Covid-19 pandemic the study was stopped prematurely. Participants could successfully adhere to the study interventions (overall attendance rate: PA: 69% vs. HE:70% at study termination). Participants also successfully completed baseline and follow-up study assessments that included a computerized cognitive testing battery and objective tests of physical performance and functional exercise capacity. No study-related adverse events occurred. Notable trends for improved cognitive performance, gait speed and 6-min walk distance were exhibited in PA compared to HE. Our study provides important preliminary information to aid the design of larger-scale RCTs of PA that may help to preserve the independence of vulnerable older adults at high risk for ADRD in community-based settings.

IntroductionOnline question-and-answer (Q&amp;A) platforms are frequently replete with extensive human resource support. This study proposes a novel methodology of a customized large language model (LLM) called Chaotic LLM-based Educational Q&amp;A System (CHAQS) to navigate the complexities associated with intelligent Q&amp;A systems for the educational sector.MethodsIt uses an expansive dataset comprising over 383,000 educational data pairs, an intricate fine-tuning process encompassing p-tuning v2, low-rank adaptation (LRA), and strategies for parameter freezing at an open-source large language model ChatGLM as a baseline model. In addition, Fuzzy Logic is implemented to regulate parameters and the system's adaptability with the Lee Oscillator to refine the model's response variability and precision.ResultsExperiment results showed a 5.12% improvement in precision score, an 11% increase in recall metric, and an 8% improvement in the F1 score as compared to other models.DiscussionThese results suggest that the CHAQS methodology significantly enhances the performance of educational Q&amp;A systems, demonstrating the effectiveness of combining advanced tuning techniques and fuzzy logic for improved model precision and adaptability.
