RESUMEN

PURPOSE: Cancer patients experience distress and anxiety when undergoing imaging studies to monitor disease status, yet these symptoms are not always appropriately identified or well-managed. This interim analysis of a phase 2 clinical trial explored feasibility and acceptability of a virtual reality relaxation (VR) intervention for primary brain tumor (PBT) patients at the time of clinical evaluation. METHODS: English speaking, adult PBT patients with previous reports of distress and upcoming neuroimaging were recruited between March of 2021 and March 2022. A brief VR session was done within 2 weeks prior to neuroimaging with patient-reported outcomes (PROs) collected before and immediately post-intervention. Self-directed VR use over the next 1 month was encouraged with additional PROs assessments at 1 and 4 weeks. Feasibility metrics included enrollment, eligibility, attrition, and device-related adverse effects with satisfaction measured with qualitative phone interviews. RESULTS: Fifty-five patients were approached via email, 40 (73%) responded and 20 (50%) enrolled (9 declines, 11 screen fails). 65% of participants were ≤ 50 years, 50% were male, 90% were White/non-Hispanic, 85% had good KPS (≥ 90), and most were on active treatment. All patients completed the VR intervention, PROs questionnaires, weekly check-ins, and qualitative interview. Most (90%) reported frequent VR use and high satisfaction and only 7 mild AEs were recorded (headache, dizziness, nausea, neck pain). CONCLUSION: This interim analysis supports feasibility and acceptability of a novel VR intervention to target psychological symptoms for PBT patients. Trial enrollment will continue to assess for intervention efficacy. TRIAL REGISTRATION: NCT04301089 registered on 3/9/2020.

RESUMEN

While many studies have found an association between childhood emotional abuse and alcohol use disorders (AUD) during adulthood, underlying psychological mechanisms linking the two remain inadequately understood. Drawing on the developmental psychopathology perspective, this study examined the relationship between childhood emotional abuse and AUD during adulthood with a national sample of women in Nepal (N = 1,100, M age = 37.73), focusing on the mediating role of borderline personality traits. Mediation analyses were performed using the Karlson-Holm-Breen (KHB) method and bootstrapping confidence intervals. Results indicated that Nepali women's borderline personality traits significantly mediated the relationship between childhood emotional abuse and AUD. Hence, emotional abuse in childhood increases the risk for AUD during adulthood for Nepali women by increasing the risk of borderline personality traits. Findings underscore the necessity of continued emphasis on developing and implementing early interventions for childhood emotional abuse and therapeutic interventions for borderline personality traits in reducing AUD among vulnerable women in Nepal.

RESUMEN

Conflicts between couples and their parents-in-law are a common phenomenon in Chinese families. In this study, in-law psychological aggression (InPA) victimization and its association with intimate partner violence (IPV), women's health, and gender role valuation were examined. A household face-to-face survey with random sampling was conducted, and a total of 260 married Chinese women with parents-in-law were recruited. Among the participants, 11.2% and 43.1% had experienced InPA victimization and IPV victimization, respectively, and 7.3% had experienced both. Women's daily contact with parents-in-law, anxiety symptoms, demand to obey parents-in-law, and the low valuation of the male role significantly positively related to InPA victimization, whereas discussions of in-law conflict with husbands were significantly negatively related to InPA victimization. Therefore, in developing interventions for women experiencing InPA victimization, the role of the husband in InPA victimization and the risk of co-occurring InPA and IPV should be considered. These findings reflect the need to raise awareness about the influence of culture on gender roles, the harm caused by InPA victimization, and the urgent need to help Chinese women who are experiencing in-law conflict.

RESUMEN

BACKGROUND: Kinship care has become a favourable alternative care option for orphans and vulnerable children without adequate parental care in Ghana. However, kinship care practices in Ghana are considered informal cultural practices without formal regulations. The absence of formal regulations could have consequences on the health and development of children due to the lack of proper supervision and empirical assessment of children's needs. In line with recent policy discussions on mechanisms to regulate informal kinship care practices, this study aimed to identify how the State could be involved in improving kinship care experience for children. METHODS: Qualitative in-depth interviews were conducted with 22 young persons (aged 18-23) who had been received into kinship care to share their experiences on how the State could be involved in improving kinship care experience for children. Narratives from the young people were analysed following the constructivist grounded theory approach. RESULTS: Introduction of a welfare scheme for kinship caregivers, policy on child care, provision of start-up capital and training for caregivers, were measures suggested by the young people to improve kinship care practice. Providing start-up capital to kinship caregivers was identified to mitigate caregivers' unemployment challenges, which could have ripple effects on the well-being of children by escalating caregiver stress. CONCLUSION: The study's findings suggest that the State has a significant role to ensure that caregivers are equipped with the needed resources to provide adequate care for children. Regulating kinship care practices should embrace a strength-based empowerment model that builds on the capacity of the caregivers to ensure better outcomes for children. Studies that explore the views of policy makers and caregivers in a larger sample may yield promising results to complement the current findings.

RESUMEN

Theoretical models and empirical studies of anxiety have predominately focused on the main effects of various predictors such as executive functioning deficits on anxiety. This study examined the moderating role of parental demandingness in the relationship between executive functioning deficits and anxiety in children. Ninety children (46.67% female) aged from 9 to 14 years completed several executive functioning tasks and a measure of anxiety. Parental demandingness was rated based on an observation of parent-child interactions. The children completed the anxiety measure again at one-year follow-up. The results showed that parental demandingness significantly moderated the prospective relationship between executive functioning deficits and anxiety, such that the association between executive functioning deficits and anxiety in children was weaker when parental demandingness was lower. These findings suggest that low parental demandingness may serve as a protective factor that buffers the detrimental effects of executive functioning deficits on anxiety.

RESUMEN

Although meningioma is the most common primary tumor of the central nervous system, the mechanism of progression from benign to atypical or anaplastic grade remains elusive. The present case reports the genomic evaluation of two synchronous meningiomas with different histological grades (benign and atypical) in the same patient. Under the assumption that the atypical tumor may have progressed from the benign tumor, the clonal origin of the lesions was investigated to identify genomic events responsible for the oncogenic process of evolution to higher grades in meningioma. A 59 year-old female patient was diagnosed with two synchronous meningiomas with different histological grades, benign and atypical. Whole-exome sequencing (WES) and RNA sequencing (RNA-seq) analysis of both tumors were done. WES analysis showed that each meningioma harbored distinct mutation profiles, and RNA-seq analysis revealed distinct gene expression profiles between the two tumors. The only apparent common genetic abnormality found in both tumors was the loss of heterozygosity of chromosome 22, raising the possibility that this event is the initial step in tumor formation, after which distinct subsequent mutations lead to the evolvement of two separate tumors of different grades. The result provides additional evidence on previous reports suggesting separate, independent mechanism of progression into higher grades in meningioma.

RESUMEN

Healthcare services constitute the first formal support that many intimate partner violence (IPV) victims receive and a link to formal welfare and psychological support. The help-seeking behavior for psychosocial support, e.g., Accident and Emergency Departments (AED) onsite counseling, is key to developing effective support for IPV victims. This study aimed to strengthen the health-welfare support link to aid IPV prevention in AEDs by investigating the acceptance and refusal of on-site counseling by IPV victims. A retrospective cohort study retrieved and reviewed all records of IPV victims presenting at the AEDs of two Hong Kong hospitals between 2010 and 2014. A total of 157 male and 823 female IPV victims were identified, 295 of whom refused on-site counseling. Bivariate and multivariate analyses were performed to examine the association between help-seeking and demographic and violent injury-related factors. The odds of help-seeking via on-site counseling were significantly lower for victims with mental illness (aOR=0.49; 95% CI=0.27, 0.88). After controlling for all demographic characteristics, mental illness, and drug abuse information, sex remained an independent predictor of help-seeking (aOR=2.62; 95% CI=1.45, 4.74); victims who had experienced >2 abuse incidents were more likely to seek help than those who had experienced ≤2 abuse incidents (aOR=1.90; 95% CI=1.11, 3.26). The factors associated with help-seeking from on-site services by IPV victims reflect the need for multidisciplinary collaborative work aimed at IPV prevention. Healthcare professionals require training on how to promote help-seeking behavior targeted specifically for male and female IPV victims according to their needs and preferences.

RESUMEN

One of the most robust findings in health economics is that higher educated individuals tend to be in better health. This paper tests whether health disparities across education are to some extent due to differences in reporting error across education. We test this hypothesis using data from the pooled National Health and Nutrition Examination Survey (NHANES) for 1999-2012, which include both self-reports and objective verification for an extensive set of health behaviors and conditions, including smoking, obesity, high blood pressure, high cholesterol, and diabetes. We find that college graduates are more likely to give false negative reports of obesity and high total cholesterol; one possible explanation for this is social desirability bias. However, college graduates are also significantly less likely to give false positive reports of smoking, obesity, and high cholesterol. Because there are far more truly negative people (who are less likely to give a false positive report) than more truly positive people (who are more likely to give a false negative report), we find that college graduates report their health significantly more accurately overall.

RESUMEN

PURPOSE: Theories explaining the impact of intimate partner violence (IPV) on mental health have focused on heterosexual relationships. It is unclear whether mental health disparities between heterosexual and sexual minority people are due to IPV or factors related to sexual orientation. The present study aimed to investigate pathways of how sexual orientation influenced quality of life and mental health. METHODS: The present cross-sectional study was conducted in 1076 young adults in a university population (934 heterosexual and 142 sexual minority groups). Structural equation modelling was used to examine the pathways of sexual orientation, dating violence, sexual orientation concealment, quality of life and mental health (perceived stress, anxiety and depression). RESULTS: After adjusting for sociodemographic factors, quality of life in sexual minority people was poorer [estimate -2.82, 95 % confidence interval (CI) -4.77 to -0.86, p = 0.005], and stress (estimate 2.77, 95 % CI 1.64-3.92, p < 0.0001), anxiety (estimate 1.84, 95 % CI 1.13-2.56, p < 0.0001) and depression levels (estimate 0.62, 95 % CI 0.05-1.2, p < 0.0001) were higher than in heterosexual people. Dating violence and sexual orientation concealment were mediators, with the models showing a good fit. CONCLUSION: Our study has progressed investigation of the link between sexual orientation and quality of life and mental health in the Chinese context. It has helped identify health disparities between heterosexual and sexual minority people and determined specific factors affecting their quality of life and mental health.

RESUMEN

BACKGROUND: Cohabitation, referring to a co-residential romantic relationship between two intimate partners without a marriage license, has become widely accepted in contemporary societies. It has been found that cohabitating women have a higher risk of experiencing intimate partner violence (IPV) than married women. However, as yet, no studies have investigated the level and pattern of IPV-associated physical injuries and its mental health impact on cohabitating women. Therefore, we aim to compare IPV-associated physical injuries between cohabitating and married women by conducting a review of 5-year medical records from the emergency departments of two major public hospitals in Hong Kong. METHODS: This is a retrospective cohort study. Using two computerized systems, we identified the medical charts of 1011 women who had experienced IPV and presented at emergency departments between 2010 and 2014, of which, 132 were cohabitating and 833 were married. RESULTS: Cohabitating women were significantly younger (p-value < .0001) and had obtained a higher educational level (p-value = .008) than married women. After adjusting for those two variables, the logistic regression models showed that cohabitating women were approximately 2.1 times more likely than married women to present with head, neck, or facial injuries (OR = 2.1, 95% CI = 1.30-3.40, p = .002), and the risk of having multiple injuries in different locations (head, neck, face, torso, limbs) was almost twice that for cohabitating women compared with married women (OR = 1.82, 95% CI = 1.25-2.65, p = .001). Furthermore, cohabitating women were almost two times as likely as married women to experience more than one method of physical violence (OR = 1.72, 95% CI = 1.18-2.51, p = .005). There were no significant differences regarding mental health, police reporting, and discharge plans. CONCLUSIONS: Owing to recent social changes to the family structure, including the growing acceptance of cohabitation, it is essential that a screening program for IPV is established for cohabitating women, as well as the inclusion of IPV content in medical and nursing curriculums and in-service training.

RESUMEN

Polychlorinated biphenyl (PCB) exposure may affect serum concentrations of polyunsaturated fatty acids (PUFAs) by inhibiting desaturases ∆5 and ∆6 that drive their synthesis from precursor fatty acids. Such changes in the composition of fatty acids may affect cardiovascular disease risk, which is thought to increase at elevated PCB exposures. This population-based cross-sectional study examined 712 Faroese men and women aged 70-74 years. The serum phospholipid fraction of fasting blood samples was used to determine the PUFA profile, including linoleic acid, dihomo-γ-linolenic acid, arachidonic acid, eicosatrienoic acid, and other relevant fatty acids. Ratios between precursor and metabolite fatty acids were used as proxies for ∆5 and ∆6 desaturase activity. Tertiles of serum-PCB concentrations were used in multiple regression analyses to determine the association between the exposure and desaturase activity. In multiple regression models, PCB exposure was inversely related to the estimated Δ6 desaturase activity resulting in accumulation of precursor fatty acids and decrease in the corresponding product PUFAs. A positive association between PCB and Δ5 desaturation was also found. A relative increase in EA was also observed, though only in the third tertile of PCB exposure. Non-linear relationships between the exposure and the desaturase activity were not found. Consuming fish and seafood may not be translated into beneficial fatty acid profiles if the diet simultaneously causes exposure to PCBs. Although the desaturase estimates were likely influenced by dietary intakes of product PUFAs, the association between PCB exposure and ∆6 desaturase activity is plausible and may affect cardiovascular disease risk.

RESUMEN

BACKGROUND: Few studies have focused on the characteristics of male victims of intimate partner violence (IPV). Providers of care lack knowledge on the pathognomonic features to identify male IPV victims, who tend to be hidden. OBJECTIVES: This study investigated the injury patterns of male IPV victims and their help-seeking characteristics. METHODS: A retrospective cohort study was carried out in two regional hospitals in Hong Kong. Data were collected from the hospital computer databases (i.e., the Accident & Emergency Information System and the Clinical Data Analysis and Reporting System) and the medical charts completed by physicians. RESULTS: Medical records were retrieved from August 1, 2009 to December 31, 2011 for all IPV victims presenting at the accident and emergency departments. There were 372 cases in total, including 54 male and 318 female cases. Male victims were more likely to have abrasions/scrapes (66.7%), human bites (20.4%), and laceration/cutting (18.5%) than female victims (31.4%, 1.3%, 6.9%; p < 0.001, p < 0.01, p < 0.001, respectively). More male victims received dressing (38.9%) and injection (13.0%) than female victims (14.5%, 3.5%; p < 0.001, p < 0.01, respectively). Fewer male victims attended consultation by the medical social worker (MSW; 5.6%) than female victims (21.7%). CONCLUSION: Abrasion wounds are the most common in male victims of IPV. Male victims have lower rates of seeking help from MSWs, and most are aged 40 years or above. This study has identified important characteristics of male victims to aid the development of a comprehensive program for early IPV detection and management.

RESUMEN

The cord-blood mercury concentration is usually considered the best biomarker in regard to developmental methylmercury neurotoxicity. However, the mercury concentration may be affected by the binding of methylmercury to hemoglobin and perhaps also selenium. As cord-blood mercury analyses appear to be less precise than suggested by laboratory quality data, we studied the interrelationships of mercury concentrations with hemoglobin in paired maternal and cord blood samples from a Faroese birth cohort (N=514) and the Mothers and Children's Environmental Health study in Korea (n=797). Linear regression and structural equation model (SEM) analyses were used to ascertain interrelationships between the exposure biomarkers and the possible impact of hemoglobin as well as selenium. Both methods showed a significant dependence of the cord-blood concentration on hemoglobin, also after adjustment for other exposure biomarkers. In the SEM, the cord blood measurement was a less imprecise indicator of the latent methylmercury exposure variable than other exposure biomarkers available, and the maternal hair concentration had the largest imprecision. Adjustment of mercury concentrations both in maternal and cord blood for hemoglobin improved their precision, while no significant effect of the selenium concentration in maternal blood was found. Adjustment of blood-mercury concentrations for hemoglobin is therefore recommended.

RESUMEN

PURPOSE: The aim of this study was to report translation and transcultural adaptation of the 15-item Dispositional Resilience Scale in traditional Chinese (C-DRS-15) and evaluate its psychometric properties. METHODS: The DRS is a self-report instrument that measures psychological hardiness. We followed an international standard of cross-cultural translation and validation of patient-reported outcome measures to create the Chinese version. Then, the translated C-DRS-15 was validated on 542 Chinese women from a population-based sample in Hong Kong. RESULTS: The internal consistency and criterion-related validity were investigated. Exploratory and confirmatory factor analysis revealed that the C-DRS-15 was supported by a modified three-factor structure in our Chinese sample (RMSEA = .06, CFI = .94, TLI = .92, and SRMR = .06). The reliability (Cronbach's α coefficient = .78) and validity were satisfactory. Total resilience score was negatively correlated with depression (p < .001), with non-depressed women scoring higher on the C-DRS-15. CONCLUSIONS: The C-DRS-15 was demonstrated to be a reliable and valid measurement to assess hardiness in Chinese women.

RESUMEN

BACKGROUND: Intimate partner violence (IPV) related injuries have been recognized among health care professionals. However, few studies have provided detailed information on injuries to the head, neck and face regions in Chinese women. As abused Chinese women are generally unwilling to disclose IPV and there are differences in socio-demographic characteristics, societal norms and behaviours, the women may exhibit different patterns, aetiology and risk factors of IPV-related HNF injuries. This study aims to examine the patterns of head, neck and face injuries presenting to Accident and Emergency departments, including the anatomical regions, types, severity, aetiology and demographic and non-demographic risk factors of injuries inflicted by intimate partners in Chinese context. METHODS: Medical charts of 223 women presented to the Accident and Emergency departments of two regional hospitals in Hong Kong between January 2010 and December 2011 were reviewed independently by two reviewers. RESULTS: Head, neck and face injuries remained the most common injuries found in abused Chinese women (77.6%), and punching with a fist was the most common aetiology (60.2%). In particular, punching with a fist was significantly associated on the upper third of the maxillofacial region (p = .01) and the back part of the head (p = .03). Moreover, cohabiting and separated women were more likely to have multiple injuries than those who were married (OR = 3.3, 95% CI = 1.4, 7.8; OR = 2.1, 95% CI = .4, 11.9). CONCLUSIONS: The findings enhance the understanding of head, neck and face injuries and inform clinicians about the linkage among injuries and risks in abused Chinese women.

RESUMEN

SARS-CoV-2, the virus responsible for the COVID-19 pandemic, has spurred the urgent need for practical diagnostics with high sensitivity and selectivity. Although advanced diagnostic tools have emerged to efficiently control pandemics, they still have costly limitations owing to their reliance on antibodies or enzymes and require high-tech equipment. Therefore, there is still a need to develop rapid and low-cost diagnostics with high sensitivity and selectivity. In this study, we generated aptamer display particles (AdP), enabling easy fabrication of a SARS-CoV-2 detection matrix through particle PCR, and applied it to diagnosis using fluorometric and colorimetric assays. We designed two AdPs, C1-AdP and C4-AdP, displayed with SpS1-C1 and SpS1-C4 aptamers, respectively, and showed their high binding ability against SARS-CoV-2 spike protein with a concentration-dependent fluorescence increase. This enabled detection even at low concentrations (0.5 nM). To validate its use as a diagnostic tool for SARS-CoV-2, we designed a sandwich-type assay using two AdPs and high-quality aptamers targeting SARS-CoV-2 pseudoviruses. The fluorometric assay achieved a detection limit of 3.9 × 103 pseudoviruses/mL. The colorimetric assay using an amplification approach exhibited higher sensitivity, with a detection limit of 1 × 101 pseudoviruses/mL, and a broad range of over four orders of magnitude was observed.

RESUMEN

The global challenges posed by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have underscored the critical importance of innovative and efficient control systems for addressing future pandemics. The most effective way to control the pandemic is to rapidly suppress the spread of the virus through early detection using a rapid, accurate, and easy-to-use diagnostic platform. In biosensors that use bioprobes, the binding affinity of molecular recognition elements (MREs) is the primary factor determining the dynamic range of the sensing platform. Furthermore, the sensitivity relies mainly on bioprobe quality with sufficient functionality. This comprehensive review investigates aptamers and nanobodies recently developed as advanced MREs for SARS-CoV-2 diagnostic and therapeutic applications. These bioprobes might be integrated into organic bioelectronic materials and devices, with promising enhanced sensitivity and specificity. This review offers valuable insights into advancing biosensing technologies for infectious disease diagnosis and treatment using aptamers and nanobodies as new bioprobes.

RESUMEN

INTRODUCTION: Pancreatic cancer cells generally accumulate large numbers of lipid droplets (LDs), which regulate lipid storage. To promote rapid diagnosis, an automatic pancreatic cancer cell recognition system based on a deep convolutional neural network was proposed in this study using quantitative images of LDs from stain-free cytologic samples by optical diffraction tomography. METHODS: We retrieved 3D refractive index tomograms and reconstructed 37 optical images of one cell. From the four cell lines, the obtained fields were separated into training and test datasets with 10,397 and 3,478 images, respectively. Furthermore, we adopted several machine learning techniques based on a single image-based prediction model to improve the performance of the computer-aided diagnostic system. RESULTS: Pancreatic cancer cells had a significantly lower total cell volume and dry mass than did normal pancreatic cells and were accompanied by greater numbers of lipid droplets (LDs). When evaluating multitask learning techniques utilizing the EfficientNet-b3 model through confusion matrices, the overall 2-category accuracy for cancer classification reached 96.7 %. Simultaneously, the overall 4-category accuracy for individual cell line classification achieved a high accuracy of 96.2 %. Furthermore, when we added the core techniques one by one, the overall performance of the proposed technique significantly improved, reaching an area under the curve (AUC) of 0.997 and an accuracy of 97.06 %. Finally, the AUC reached 0.998 through the ablation study with the score fusion technique. DISCUSSION: Our novel training strategy has significant potential for automating and promoting rapid recognition of pancreatic cancer cells. In the near future, deep learning-embedded medical devices will substitute laborious manual cytopathologic examinations for sustainable economic potential.

RESUMEN

Background: Glioblastoma (GBM) is the most aggressive primary brain malignancy with <45% living a year beyond diagnosis. Previously published investigations of long-term survivors (LTS) provided clinical data but rarely incorporated a comprehensive clinical and molecular analysis. Herein, we identify clinical, imaging, molecular, and outcome features for 23 GBM-LTS patients and compare them with a matched cohort of short-term survivors (STS). Methods: Molecularly confirmed Isocitrate Dehydrogenase (IDH) wildtype GBM patients living ≥3 years post-diagnosis (NLTS = 23) or <3 years (NSTS = 75) were identified from our Natural History study. Clinical and demographic characteristics were compared. Tumor tissue was analyzed with targeted next generation sequencing (NGS) (NLTS = 23; NSTS = 74) and methylation analysis (NLTS = 18; NSTS = 28). Pre-surgical MRI scans for a subset of LTS (N = 14) and STS control (N = 28) matched on sex, age, and extent of resection were analyzed. Results: LTS tended to be younger. Diagnostic MRIs showed more LTS with T1 tumor hypointensity. LTS tumors were enriched for MGMTp methylation and tumor protein 53 (TP53) mutation. Three patients with classic GBM histology were reclassified based on NGS and methylation testing. Additionally, there were LTS with typical poor prognostic molecular markers. Conclusions: Our findings emphasize that generalized predictions of prognosis are inaccurate for individual patients and underscore the need for complete clinical evaluation including molecular work-up to confirm the diagnosis. Continued accrual of patients to LTS registries that containcomprehensive clinical, imaging, tumor molecular data, and outcomes measures may pro\vide important insights about individual patient prognosis.

RESUMEN

OBJECTIVES: To study the impact of a financial education program on financial well-being among college students. PARTICIPANTS: 162 students at a university. METHODS: We designed a digital educational intervention to improve money management practices and financial well-being among college students, where we delivered weekly nudges for three months via mobile phone and email to review and complete activities from the online platform CashCourse. We evaluated our intervention using a randomized controlled trial (RCT), and the outcome variables of interest were the financial self-efficacy scale (FSES) and financial health score (FHS). RESULTS: Using a difference-in-difference regression analysis we found that students in the treatment group were significantly more likely to pay their bills on time after the intervention compared to the control group. Students who had higher than median financial self-efficacy level reported lower stress levels related to COVID-19. CONCLUSIONS: Digital education programs for college students to improve financial knowledge and behavior could be one strategy, among others, to improve financial self-efficacy particularly among females and help mitigate the adverse impact from unexpected financial hardships.
