Gender Self-Identification: Opinions About Transgender Women from a National Online Survey in Taiwan.

Gender self-identification (transgender) is not permitted in most Asian countries. In Taiwan, individuals recognized as transgender must meet requirements mandated by the Gender Recognition Act. Currently, lifting the requirement for proof of sex-reassignment surgery is pending. The aim of this study was to survey a large sample of Taiwanese to gain a better understanding of the general population's attitudes toward gender self-identification. A self-report survey, entitled "Opinions of Gender Self-Identification," collected demographic information and responses (agree = 1, disagree = 0) to 14 statements about transgender women and women's safety, personal rights, and the law; one statement discussed rights of transgender men to give birth; total scores ranged from 0 to 14. The online survey was distributed to non-government organizations across Taiwan and the Taiwanese islands and was available between April 16 and 30, 2022. Most of the 10,158 respondents were female (77.4%); ages of respondents ranged from 15 to > 65 years. The mean total score was 0.95 ± 2.27, indicating respondents strongly disagreed with support for transgender females; 91.56% disagreed with all statements. Although there were significant differences in scores between parents and non-parents, and those ≤ 35 years versus ≥ 36 years (p < .01), all strongly disagreed with gender self-identification. Given the majority of respondents were females, survey findings should be regarded with caution. Public acceptance of gender self-identification requires support from its residents. Our findings suggest that gender self-identification has not begun to approach even a moderate level of public support among survey respondents.

Impact of class cancellations on parents' and children' adaptation following an outbreak of the Omicron variant during the COVID-19 pandemic in Taiwan in April 2022.

OBJECTIVE: To explore the impact on Taiwanese parents and children following an outbreak of the Omicron variant during the COVID-19 pandemic. METHODS: Data were collected following class cancellations mandated by the Ministry of Education due to an outbreak of the Omicron variant of COVID-19 in April 2022. A national parent organization developed self-report survey questionnaire, "Impact of the Pandemic-related School Closures/Class Cancellations" (IPRSCCC), assessed parents' perceived impact of school cancellations on their child/children' and on their adaptation. The online survey was available between May 4 and May 9, 2022, in 20 districts throughout Taiwan. RESULTS: A total of 2126 parents representing 2592 children responded. Total scores on the IPRSCCC were significantly higher for parents of children whose classes were cancelled (n = 891) compared with parents whose children continued in-person classes (n = 1053). Parents perceived the class cancellations of the child/children disrupted daily routine, learning loss and impacted academic motivation. They also reported emotional stress and no time for rest, which were associated with parental burnout. However for these parents, there were no significant differences in scores between parents living in low and high socioeconomic areas. Only the subscale score for disrupted daily routine was significantly higher for fathers, and emotional stress was significantly higher for parents with two, or ≥ 3 children. When academic impacts were examined using national examination scores for 12th grade students, the percent of students with scores of ≤ 6 in English, Chinese, and mathematics was higher in 2022 than in 2020. CONCLUSIONS: Higher IPRSCCC scores for parents of children whose classes were cancelled provides additional evidence of the impact of disruptions of in-person classes due to the COVID-19 pandemic. Examination scores confirmed class cancellations impacted academic performance.

Prevalence and Comorbidity of Gender Dysphoria in Taiwan, 2010-2019.

Gender dysphoria (GD) is a condition in which a person exhibits marked incongruence between their expressed or experienced gender and their sex assigned at birth. The last survey of individuals with GD in Taiwan was conducted approximately 10 years ago. In this study, we investigated the prevalence of GD in Taiwan within the last 10 years as well as comorbidities. A retrospective medical record review was performed for all patients in the database of the Health and Welfare Data Science Center covered by National Health Insurance in Taiwan from January 2010 until December 2019. The study population of persons with GD was defined as individuals who had been diagnosed with transsexualism (transgender or transsexual) or gender identity disorders. Our review found case numbers and prevalence of GD in 2019 were about twice that of patients in 2010 for both assigned males and assigned females at birth. Case numbers for 2010 versus 2019 were 440 versus 867 for assigned males at birth, and 189 versus 386 for assigned females at birth. The 1-year prevalence for 2010 versus 2019 was 3.8/100,000 versus 7.4/100,000 for assigned males at birth, and 1.6/100,000 versus 3.2/100,000 for assigned females at birth. Comorbidities of attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and psychosis were more likely in children with GD younger than 12 years of age; comorbid depression was more likely in adolescents and adults with GD. Improvements in social and mental health support should be provided to help address these comorbidities of ADHD, ASD, and depression among individuals with GD.

Legalization of marijuana or not? Opinions from over 38,000 residents in Taiwan.

BACKGROUND: Marijuana is legal in many Western countries and Thailand. In Taiwan, Marijuana remains a category-2 narcotic; however, some legislative candidates recently advocated legalization of medical marijuana. This study surveyed a large sample of Taiwanese to gain a better understanding of the public's knowledge and attitudes towards legalizing marijuana. METHODS: This cross-sectional mixed-methods study included demographic data and responses to a survey questionnaire, "Knowledge and Attitudes of Legalizing Marijuana" (KALM). The survey included 15 statements about four categories: public health, social impact, medical applications of THC (Δ9-tetrahydrocannabinol), and legal and tax consequences; and two yes/no questions about medical use and legalization of marijuana. Knowledge was scored as disagree = 0, no knowledge = 2, or agree = 4; attitude was scored from 0 = very unimportant to 4 = very important. Responses to an open-ended question asking for additional comments/concerns were analysed with content analysis. The survey was conducted from February 15 to March 1, 2023. RESULTS: Data were analysed from 38,502 respondents, aged 15 to > 56 years. Most were female (67.1%) and parents (76.4%). Scores were higher for respondents who were parents, religious, ≥ 36 years of age, had a high-income status, no history of substance abuse, knowledge of medical marijuana, and did not support legalization of marijuana. Medical personnel had greater knowledge of marijuana, but their attitude indicated they viewed legalization as less important. In the open-ended question, many respondents requested more information about marijuana be provided to the public before considering legalization. CONCLUSIONS: Taiwanese respondents considered legalization of marijuana a significant concern, especially as it relates to impacts on public health.

Towards stimulated Raman scattering spectro-microscopy across the entire Raman active region using a multiple-plate continuum.

Stimulated Raman scattering (SRS) has attracted increasing attention in bio-imaging because of the ability toward background-free molecular-specific acquisitions without fluorescence labeling. Nevertheless, the corresponding sensitivity and specificity remain far behind those of fluorescence techniques. Here, we demonstrate SRS spectro-microscopy driven by a multiple-plate continuum (MPC), whose octave-spanning bandwidth (600-1300 nm) and high spectral energy density (∼1 nJ/cm-1) enable spectroscopic interrogation across the entire Raman active region (0-4000 cm-1), SRS imaging of a Drosophila brain, and electronic pre-resonance (EPR) detection of a fluorescent dye. We envision that utilizing MPC light source will substantially enhance the sensitivity and specificity of SRS by implementing EPR mode and spectral multiplexing via accessing three or more coherent wavelengths.

CyberLimb: a novel robotic prosthesis concept with shared and intuitive control.

BACKGROUND: Existing assistive technologies attempt to mimic biological functions through advanced mechatronic designs. In some occasions, the information processing demands for such systems require substantial information bandwidth and convoluted control strategies, which make it difficult for the end-user to operate. Instead, a practical and intuitive semi-automated system focused on accomplishing daily tasks may be more suitable for end-user adoption. METHODS: We developed an intelligent prosthesis for the Cybathlon Global Edition 2020. The device was designed in collaboration with the prosthesis user (pilot), addressing her needs for the competition and aiming for functionality. Our design consists of a soft robotic-based two finger gripper controlled by a force-sensing resistor (FSR) headband interface, automatic arm angle dependent wrist flexion and extension, and manual forearm supination and pronation for a shared control system. The gripper is incorporated with FSR sensors to relay haptic information to the pilot based on the output of a neural network model that estimates geometries and objects material. RESULTS: As a student team of the Munich Institute of Robotics and Machine Intelligence, we achieved 12th place overall in the Cybathlon competition in which we competed against state-of-the-art prosthetic devices. Our pilot successfully accomplished two challenging tasks in the competition. During training sessions, the pilot was able to accomplish the remaining competition tasks except for one. Based on observation and feedback from training sessions, we adapted our developments to fit the user's preferences. Usability ratings indicated that the pilot perceived the prosthesis to not be fully ergonomic due to the size and weight of the system, but argued that the prosthesis was intuitive to control to perform the tasks from the Cybathlon competition. CONCLUSIONS: The system provides an intuitive interface to conduct common daily tasks from the arm discipline of the Cybathlon competition. Based on the feedback from our pilot, future improvements include the prosthesis' reduction in size and weight in order to enhance its mobility. Close collaboration with our pilot has allowed us to continue with the prosthesis development. Ultimately, we developed a simple-to-use solution, exemplifying a new paradigm for prosthesis design, to help assist arm amputees with daily activities.

Stressors experienced by children with autism spectrum disorder in Taiwan: Perspectives of children and their parents.

Autism spectrum disorder has only recently been recognized as a developmental disability in Taiwan. We conducted an exploratory qualitative descriptive study with children (n = 14, mean age = 13.57 years) and their parents to understand stressors experienced by children with autism spectrum disorder in Taiwan. An analysis of face-to-face interviews revealed that children with autism spectrum disorder experienced stressors of daily living, which included environmental stimuli, academic and behavioral expectations, deviations in routine, behavioral expectations, and emotional control, and stressors of socializing, which included bullying, communication, personal interactions, conflict resolution, and difficulty understanding others' emotions. Stressors resulted from the core symptoms and characteristic behaviors of autism spectrum disorders, and also Taiwanese cultural expectations. Our findings could help develop individualized educational plans and culturally-sensitive behavioral interventions. Facilitation of these interventions could be used by nurses and health-care professionals to help facilitate problem solving and communication skills, which could reduce the stress for children with autism spectrum disorder in Taiwan.

Coping strategies of Taiwanese children with autism spectrum disorders.

AIMS AND OBJECTIVES: To explore and describe the coping experiences of children with autism spectrum disorders in Taiwan. BACKGROUND: Children with autism spectrum disorders are faced with daily social and living challenges, which can cause stress. Chinese culture emphasises discipline and obedience, which may influence coping strategies of children with autism spectrum disorders in Taiwan. DESIGN: This qualitative study employed an exploratory descriptive design. METHOD: Data were collected from in-depth, face-to-face structured interviews. Interviews explored coping strategies of Taiwanese school-aged children (aged 6-19) with autism spectrum disorders. Children (N = 17) and their caregivers were recruited by purposive sampling. Transcribed interview data were thematically analysed using the procedure of Miles and Huberman. RESULT: Five themes emerged from the analysis of the data, which described the coping strategies of the children: (1) problem-solving, (2) acting-out, (3) avoidance, (4) seeking help and (5) self-regulation. These themes included multiple coping strategies, which employed the concepts of engagement and disengagement. CONCLUSIONS: The children with autism spectrum disorder used many strategies to cope with the stresses resulting from behaviours and symptoms associated with the disorder. Most of the Taiwanese children use both problem-solving and emotional-focused coping strategies. RELEVANCE TO CLINICAL PRACTICE: Understanding coping strategies of children with autism spectrum disorder could help caregivers (parents, teachers) and medical professionals develop interventions to reduce these challenges, which could alleviate stress and improve social functioning for these children.

Hb and dyslipidaemia as predicting markers of serum alanine aminotransferase elevation in Chinese adolescents.

OBJECTIVE: Fe is an essential element for erythropoiesis and Hb synthesis. High Hb levels affect the blood's viscosity and are associated with cardiovascular dysfunction. The aim of the present study was to examine relationships of Hb and cardiometabolic abnormalities with the risk of alanine aminotransferase (ALT) elevation in adolescents. DESIGN: A population-based, cross-sectional study. SETTING: National Nutrition and Health Survey in Taiwan (2010-2011, adolescents). SUBJECTS: Healthy adolescents aged 13-18 years. RESULTS: In total, 1941 adolescents (963 boys and 978 girls) were entered in the study. The mean age was 15·3 (sd 0·1) years (boys, 15·3 (sd 0·1) years; girls, 15·2 (sd 0·1) years). ALT tertile cut-off points for boys were 11 and 16 U/l, and for girls were 9 and 12 U/l. Girls without dyslipidaemia and presenting in the highest quartile (Q1) of Hb (>13·6 g/dl) were 1·89 and 3·76 times more likely to have raised serum ALT (9 and >12 U/l, respectively) than the reference (lowest quartile of Hb (Q1), 12 U/l) than the reference (Q1 of Hb, 15·4 g/dl), who were 7·40 times more likely to have elevated serum ALT of >16 U/l than the reference (Q1 of Hb, <14·1 g/dl). CONCLUSIONS: Our findings suggest that an increased Hb level is a predictor of elevated serum ALT in adolescent girls with dyslipidaemia. Our study also highlights the importance of further research to establish cut-off points for Hb and its utility in diagnosing and preventing the onset of dyslipidaemia in adolescents.

Interleukin 10 and clustering of metabolic syndrome components in pediatrics.

BACKGROUND: Interleukin 10 (IL-10) has multifaceted anti-inflammatory properties that are known to regulate insulin sensitivity and atherosclerotic development. However, studies in children are limited and have yielded conflicting results. The aim of this study was to evaluate whether changes in this circulating anti-inflammatory cytokine is a marker for metabolic syndrome. MATERIALS AND METHODS: This cross-sectional study involved children and young adolescents from eight elementary schools and two junior high schools located in Taipei and New Taipei City. A total of 553 children ages 8, 11 and 13 years old were included in the analysis. Parameters for obesity, anti- and pro-inflammatory cytokines, and metabolic risk profiles were evaluated. RESULTS: Overweight/obese children had lower serum IL-10 concentrations compared with normal weight children in the same age group (all P < 0·001). IL-10 quartiles were negatively associated with body mass index (BMI) and percentage (%) body fat (all P < 0·05). Multivariate regression analysis showed significant inverse relationship between IL-10 concentrations and % body fat (ß = -0·009, P < 0·0001), and total cholesterol (ß = -0·726, P = 0·003), and a small positive correlation between IL-10 and systolic blood pressure (ß = 0·980, P = 0·027). In normal weight children, IL-10 concentrations were independently associated with fasting plasma insulin (ß = 0·2912, P = 0·001) and waist circumference (ß = 0·0069, P = 0·022). By contrast, % body fat (ß = -0·016, P = 0·0009) was independently associated with IL-10 concentrations in overweight and obese children. Association between IL-10 and fasting plasma insulin concentrations was weaker in overweight/obese children compared with normal weight (ß = 0·283, P = 0·011 vs. ß = 0·2912, P = 0·001). CONCLUSION: Our data indicate that changes in circulating IL-10 concentrations are marker of metabolic risk in children.

Usefulness of cone-beam computed tomography-reformatted epidurography in percutaneous epidural adhesiolysis: A pilot study.

BACKGROUND: Conventional epidurography (CE) is thought to have insufficient usefulness on percutaneous epidural adhesiolysis (PEA). We aimed to evaluate the association between the outcome of PEA and cone-beam computed tomography-reformatted epidurography (CBCT-RE). METHODS: After ethics board approval and written informed consent were obtained, we performed 30 PEA in 26 participants, and evaluated their post-PEA image findings. Two independent radiologists categorized and recorded the occurrence of contrast in the intracanal ventral and extraforaminal regions on CE, and in the dorsal canal (DC), ventral canal (VC), dorsal foramen (DF), and ventral foramen (VF) on CBCT-RE. Reproducibility was assessed using intraclass correlation coefficients (ICCs). Baseline characteristics along with contrast distribution patterns of CE and CBCT-RE were analyzed in terms of their association with symptom relief at 1 month after PEA. RESULTS: The rate of patients with symptoms relief >50% after PEA was 63.3%. The inter-reader agreement was higher for CBCT-RE (ICC = 0.955) than for CE (ICC = 0.793). Participants with contrast coexisting in VC and DF adjacent to the irritated nerve root on CBCT-RE ( p = 0.015) had a significantly better response after PEA than those without contrast at these locations on CBCT-RE, independent of baseline characteristics (adjusted odds ratio: 11.414 [ p = 0.012]). CONCLUSION: CBCT-RE with identifying contrast distribution patterns is useful for predicting outcome of PEA.

Association between interleukin 1ß and interleukin 10 concentrations: a cross-sectional study in young adolescents in Taiwan.

BACKGROUND: In adults, low circulating interleukin 10 (IL10) has been associated with obesity and type 2 diabetes. However, studies investigating IL10 in overweight and obese children have yielded conflicting results. The aim of this study was to investigate factors associated with serum IL10 concentration in young Chinese adolescents. METHODS: Young adolescents (n=325) ages 13.33±1.10 years were recruited into the cross-sectional study from 2010 to 2011. Parameters of obesity, individual components of MetS, iron status and serum IL10 were evaluated. RESULTS: Compared with their normal weight counterparts, overweight adolescents had lower serum IL10 but higher TNFα, nitric oxide (NO) and IL1ß concentrations (all p<0.05). Obese adolescents had increased IL1ß but decreased hepcidin concentration compared with normal weight (p<0.01 and p<0.05; respectively). A strong inverse relationship (p<0.0001) was found between IL10 and pro-inflammatory cytokines (TNFα and IL1ß). Multivariate linear regression analysis showed serum IL1ß was significantly correlated with IL10 (ß=-0.156, p<0.0001). When overweight and obese adolescents were assessed separately from normal weight, only IL1ß was inversely associated with serum IL10 (ß=-0.231, p=0.0009). The association between IL10 and IL1ß was weaker in adolescents with normal weight (ß=-0.157, p=0.0002), after adjusting for gender, TNFα, IFNγ and NO. CONCLUSIONS: Our study confirmed that low IL10 concentration is associated with overweight and obesity in young adolescents. We also demonstrated for the first time that pro-inflammatory cytokine IL1ß is independently associated with IL10. A decline in IL10 concentration in overweight and obese adolescents may further contribute to the IL1ß-mediated inflammatory environment associated with obesity.

Exploring Coping Strategies of Parents of Children With Autism Spectrum Disorder in Taiwan: A Qualitative Study.

BACKGROUND: Children with autism spectrum disorder (ASD) experience impairments in their social interactions, language communication, and stereotypical patterns of behavior. Parents of children with ASD experience higher levels of stress and more depression and anxiety than parents of children with other disabilities or typically developing children. Parents of children with disabilities develop coping strategies to counteract the stresses associated with raising a child with special needs. Understanding coping strategies to help counteract the stresses associated with parenting a child with ASD may enhance well-being in parents of children with ASD, improve the quality of care provided to these children, and foster better parent-child relationships. PURPOSE: The purpose of this study was to explore the coping strategies used by parents in Taiwan parenting a child with ASD. METHODS: In this descriptive qualitative study, thematic analysis was conducted on data collected during face-to-face interviews. Fourteen parents of children with ASD were recruited using purposive sampling. Researchers employed a teamwork approach for data analysis to increase the dependability and consistency of the transcribed interviews. Team members discussed coding and identified the themes collaboratively. RESULTS: Taiwanese parents of children with ASD coped with the psychological impacts of parenting by employing problem-focused and emotion-focused strategies. Problem-focused strategies included communication, support, and management, whereas emotion-focused strategies included acceptance and adaptation. Findings showed that both coping strategies were useful in addressing specific situations and circumstances. Social and clinical support improved parents' mental health and children's external behaviors. CONCLUSIONS/IMPLICATION FOR PRACTICE: Healthcare providers should evaluate how parents are coping with the stresses related to raising a child with ASD and consider the cultural factors that might influence how they accept and adapt to parenting children with ASD. Understanding these variables may be used to tailor strategies appropriate to reducing stress and improving the well-being of parents and their children. Support and resource referrals should be considered, including parent support groups, books, web-based services, and recommendations for professional consultations with social workers or therapists.

Patent blue versus methylene blue and indigo carmine as a better dye for chromodiscography: in vitro staining efficacy and cytotoxicity study using bovine coccygeal intervertebral discs.

BACKGROUND CONTEXT: Chromodiscography is an integral part of full-endoscopic discectomy (FED), comprising ordinary discography with radiopacity produced by contrast medium and intradiscal stain for visualizing annular defects in the endoscopic field. Nevertheless, concerns remain about the cytotoxicity of the stains used. The study of their staining efficacy is also lacking. PURPOSE: To evaluate the feasibility of methylene blue, patent blue, and indigo carmine for intradiscal injection, investigate the effectiveness of each dye, and define critical concentration with adequate staining efficacy and tolerable cytotoxicity for use in chromodiscography during FED. STUDY DESIGN: An experimental in vitro study. METHODS: Dye stock solutions were prepared from powder. The stock was diluted with culture medium or balanced saline and used for cytotoxicity or intervertebral disc staining assays, respectively. Bovine tails were obtained from the local slaughterhouse and functional spine units of intervertebral discs were acquired by transverse incision at the disc level. Each disc was punctured over the posterolateral aspect using a surgical knife to simulate an annular defect. The intradiscal injection was performed with each dye at different concentrations using a 22G needle from the contralateral aspect of the punctured site. Staining efficacy was quantified using ImageJ software. Primary cells of bovine tails were cultivated in each dye at different concentrations. Cytotoxicity was assessed 24 hours after stain exposure using the CCK-8 toxicity assay. RESULTS: Staining efficacy and cytotoxicity were proportional to the concentration of tested dyes. Lower limits of concentration producing significant staining efficacy of indigo carmine, methylene blue, and patent blue were 0.25 mg/mL, 0.25 mg/mL, and 0.05 mg/mL, respectively. Compared with controls, concentrations showing significant toxicity for indigo carmine, methylene blue, and patient blue were 1 mg/mL, 0.5 mg/mL, and 2.5 mg/mL, respectively. CONCLUSIONS: Patent blue can serve as a more suitable tissue stain than either indigo carmine or methylene blue due to the widest range of tradeoff concentration within 0.05 to 2.5 mg/mL. CLINICAL SIGNIFICANCE: Patent blue with the characteristic of good staining efficacy and lower cytotoxicity may be a promising option for chromodiscography during FED.

Impact of Taiwan's 2021 COVID-19 lockdown on the symptom severity and quality of life of patients with narcolepsy.

COVID-19 lockdowns can influence the sleep quality and daytime condition of patients with narcolepsy. Using data from our cohort study, we investigated changes in the quality of life and the symptom severity of patients with narcolepsy during Taiwan's 2021 lockdown and investigated differences by narcolepsy subtype, sex, and age. Patients with type 1 and type 2 narcolepsy (NT1 and NT2, respectively) aged 6-40 years were retrospectively recruited from our narcolepsy cohort study. These patients were regularly evaluated using the Short Form 36 Health Survey questionnaire (SF-36), the Epworth Sleepiness Scale (ESS), the visual analog scale (VAS) for hypersomnolence, the VAS for cataplexy and sleep diary. We compared the differences between the lockdown and the prelockdown periods by narcolepsy subtype, sex, and age. We used a paired t test analysis to compare differences in the SF-36, ESS, VAS scores and data of sleep diary between the prelockdown and lockdown periods (p1), and an independent t test analysis was used to compare the changes in different subgroups between the prelockdown and lockdown periods (p2). A total of 120 patients with narcolepsy were recruited (mean age 24.22 ± 6.87 years; 58% male); 80 of the patients had NT1 (mean age 25.25 ± 6.79 years; 60% male) and 40 had NT2 (mean age 22.16 ± 6.64, 53% male). During the lockdown period, the ESS score of total patients was decreased (p = 0.039) and body mass index was increased (p = 0.02). The NT1 group decreased significantly (p1 = 0.017), especially in men (p1 = 0.016) and adults (p1 = 0.04); scores for the VT domain of the SF-36 increased significantly in male and adult patients with NT2 (p1 = 0.048 and 0.012). Additionally, male patients with NT2 exhibited significantly decreased scores in the physical and emotional role functioning domains (p1 = 0.028, 0.024). The children and adolescents with NT1 had significantly decreased scores in the general health domain of the SF-36, but no significant change was noted in that of adults (p1 = 0.027, p2 = 0.012). We observed both negative and positive impacts of Taiwan's 2021 lockdown on patients with narcolepsy. A more flexible but structured daily routine with adequate sleep time should be considered for this population during lockdown and nonlockdown periods.

Electronic Preresonance Stimulated Raman Scattering Spectromicroscopy Using Multiple-Plate Continuum.

Stimulated Raman scattering (SRS) spectromicroscopy is a powerful technique that enables label-free detection of chemical bonds with high specificity. However, the low Raman cross section due to typical far-electronic resonance excitation seriously restricts the sensitivity and undermines its application to bio-imaging. To address this bottleneck, the electronic preresonance (EPR) SRS technique has been developed to enhance the Raman signals by shifting the excitation frequency toward the molecular absorption. A fundamental weakness of the previous demonstration is the lack of dual-wavelength tunability, making EPR-SRS only applicable to a limited number of species in the proof-of-concept experiment. Here, we demonstrate the EPR-SRS spectromicroscopy using a multiple-plate continuum (MPC) light source able to examine a single vibration mode with independently adjustable pump and Stokes wavelengths. In our experiments, the C═C vibration mode of Alexa 635 is interrogated by continuously scanning the pump-to-absorption frequency detuning throughout the entire EPR region enabled by MPC. The results exhibit 150-fold SRS signal enhancement and good agreement with the Albrecht A-term preresonance model. Signal enhancement is also observed in EPR-SRS images of the whole Drosophila brain stained with Alexa 635. With the improved sensitivity and potential to implement hyperspectral measurement, we envision that MPC-EPR-SRS spectromicroscopy can bring the Raman techniques closer to a routine in bio-imaging.

Human umbilical cord mesenchymal stem cells suppress breast cancer tumourigenesis through direct cell-cell contact and internalization.

The purpose of this study was to investigate how human umbilical cord mesenchymal stem cells (HUMSCs) affect breast cancer tumourigenesis. To observe the influence of HUMSCs on tumourigenesis in vitro, we performed a co-culture of MDA MB-231 breast cancer cells with HUMSCs, and a result of HUMSCs on tumourigenesis in vivo was achieved by injection of HUMSCs into nonobese diabetic/severe combined immunodeficient mice following tumour establishment with MDA-MB231. During the co-culture, apoptosis of MDA-MB231 was noted, which was driven either by binding with HUMSC through direct cell-cell contact or by formation of a novel cell-in-cell phenomenon after internalization of HUMSC. Also, treatment with HUMSC injection was efficacious in both in situ and metastatic breast cancers in the animal models. Since HUMSCs were proved to efficaciously suppress breast cancer tumourigenesis both in vitro and in vivo, it is our expectation that treatment with HUMSCs can be a viable therapy for breast cancer in the near future. In addition, we share a new point of view on the role of HUMSCs in foetal development during pregnancy.

Integration of a service-learning component into a course on nursing care for children with developmental disorders: A mixed-methods study.

BACKGROUND: Service-learning provides nursing students with hands-on experience in a real-world setting. Students learn how to care for others and manage their emotions. AIM: This study examined the effectiveness of integrating service-learning into a nursing course on nursing care for children with developmental disorders. DESIGN: This was a mixed-methods study with two pretest-posttest quantitative analyses and a qualitative component. METHODS: Nursing students (N = 74) enrolled in a semester-long course in nursing care for children with developmental disorders participated in the study. Data were collected between February 2017 and June 2021. The service-learning part of the course assigned teams of two to three students to provide nursing care for a child (ages 5-19 years) diagnosed with a developmental disorder. At the conclusion of the course, students presented a short video with reflections of their experiences. Pretest versus post-test scores compared mid-term and final exam scores regarding knowledge of children with developmental disorders and scores on a 9-item self-report instrument on service-learning skills. Self-reflections from the video presentation provided qualitative data about the impact on students' awareness of the caregiving needs of children with developmental disorders. RESULTS: The mean final exam scores were significantly higher compared with midterm scores (96.12, (SD = 4.63) vs 94.82 (SD = 12.08); F = 6.81, p < .001), indicating knowledge of developmental disabilities had increased. Pretest vs posttest scores for service-learning skills indicated confidence had significantly increased (p < .001). Students' video reports indicated sensitivity to the challenges and needs of these children had increased. CONCLUSIONS: Service-learning exposed nursing students to the challenges and rewards of caring for children with developmental disorders. Knowledge, as well as confidence, increased. Nurse educators could easily integrate service-learning into courses required as part of the curriculum for pediatric nursing students.

Survey Responses of School Closures During the COVID-19 Outbreak in Taiwan.

Background: Taiwan faced a surge of COVID-19 infections in May 2021. Because new cases were quickly increasing, parents called for school closures. A national parent group used an online survey to collect opinions about upcoming school closings planned by the Ministry of Education. This study evaluated the results of the survey for all respondents and investigated the level of viral transmission following school closures among students in Taiwan. Methods: An online survey titled "Survey of Opinions of School Closures during the Current COVID-19 Outbreak" (SOSC-COVID-19) was designed by the national parent association and then distributed to members of the community throughout Taiwan via local parent groups from May 17 to 18, 2021. The survey included an open-ended respondents' opinions about school closures. Differences among regions and socioeconomic scores (SES) were analyzed with chi-square tests. Results: A total of 8,703 completed survey forms data were analyzed. Nearly all respondents (7,973, 91.6%) approved of school closures; there were no differences of opinions inside and outside municipalities or by regional SES scores. Only 8.4% of respondents were opposed to any type of school closure, believing parents should decide whether their child attended school, which also did not vary with region or SES score. Qualitative feedback from parent and teacher responders indicated students' health and economic impacts were additional concerns that influenced their choice of whether the government or parents should decide about school closures. On the afternoon of May 18, 2021, the government of Taiwan closed all schools. Although a spike in new cases of COVID-19 occurred among students 10 days after school closures, over the next 40 days new cases declined, falling to zero by July 5th. Conclusions: Despite the inability of nationwide school closures to completely halt transmission of the virus within families during the COVID-19 outbreak, school closures helped to impede transmission between students.

An Effective Life-Sex-Emotions Course for Taiwanese Adolescents on Health Perceptions: A Cohort Study.

Aim: Adolescence is a time of transition from childhood to adulthood, when young people go through a number of vital physical and psychological developments. It is surprising yet unfortunate that the number of teenage suicide deaths and teenage infections of gonorrhea have increased over the years, becoming serious public health concerns in Taiwan. The aim of this study was to investigate the effect of an education course on teenagers' understanding of adolescence and their attitudes toward life, sex, gender equality, and mental health. Material and Methods: Participants were comprised of Taiwanese students in Grades 5 to 9 who completed a Life-Sex-Emotions course, titled "Sailing through Adolescence." The effect of the course was measured using pre- and post-test scores on the Perception Index of Life-Sex-Emotions Education (PILSEE) instrument. Qualitative data included subjective responses to questions before and after the course. Data were collected between September 2017 and June 2020. Results: A total of 10,506 completed questionnaires were collected. The mean PILSEE pretest scores for each subscale ranged from 8.71 to 13.37 (SD = 1.499-1.99); posttest subscale scores ranged from 9.30 to 13.95 (SD range = 1.490-2.288). The mean overall pretest score was 86.86 (SD = 10.83); the mean posttest score was 92.62 (SD = 10.30). The paired t-test demonstrated that post-test scores were significantly higher than pretest scores (t = 55.46; p < 0.01). Qualitative feedback indicated that the course improved students' self-esteem, their understanding adolescence, and awareness of influences of the media. Conclusion: Our findings indicate that an educational course about life, sex, and emotions during adolescence can be an effective intervention to help teenagers understand the impact of adolescence on attitudes toward life, sex, mental health, and gender equality.
