OBJECTIVES

o demonstrate the utility of the supraclavicular artery island flap (SCAIF) as a viable alternative to free tissue transfer for reconstruction of large cervicofacial defects.

METHODS

Design:Case Report

Setting:Tertiary National University Hospital

Patient: One

RESULTS

A 43-year-old woman with a giant cavernous hemangioma measuring 21.43 x 9.91 x 20.75cm underwent tumor resection and immediate reconstruction using SCAIF. Following preoperative embolization and complete tumor excision, an 11 x 15cm cervicofacial defect was successfully reconstructed using SCAIF. The patient experienced post-operative complications including multiple wound dehiscences and hypertrophic scar formation but achieved significant functional and aesthetic improvement. At three months follow up, the patient reported cessation of bleeding episodes, improved feeding capacity, and enhanced quality of life despite persistent tracheostomy dependence. Plans for secondary surgery include scar revision, commissuroplasty, and intralesional steroid injections.

CONCLUSION

The supraclavicular artery island flap presents a practical, cost-effective alternative to free tissue transfer for extensive cervicofacial reconstruction, particularly in resource-limited environments or in patients where free tissue transfer is contraindicated. Advantages include good color match, wide arc of rotation, and ease of harvest. Despite potential complications, it offers excellent functional and aesthetic outcomes with acceptable donor site morbidity.

BACKGROUND

Organizational commitment strengthens care delivery and system responsiveness, yet high turnover and workforce exhaustion threaten healthcare stability. Understanding factors that sustain commitment is especially critical during crises such as the COVID-19 pandemic.

AIM

This study examined how nurses' attitudes toward their practice environment predict organizational commitment at King Abdullah Medical City (KAMC), Makkah, Saudi Arabia.

DESIGN

Across-sectional predictive correlational design was used.

METHODS

Data was collected from 275 staff nurses between October and November 2020 using convenience sampling. Attitudes toward the practice environment were assessed with the Practice Environment Scale of the Nursing Work Index (PESNWI), while organizational commitment was measured using the Revised Three-Component Model Employee Commitment Survey. Descriptive statistics, Pearson's correlations, and multiple regression were conducted in SPSS version 21.

RESULTS

Nurses reported positive work attitudes, with the highest ratings for nursing care and interdisciplinary relationships, followed by management and leadership, and the lowest for adequate resources. Organizational commitment was moderate across affective, normative, and continuance domains. Regression analyses identified nursing care and interdisciplinary relationships as the most consistent predictor across all domains of commitment, including affective (p < .001), normative (p = .047), continuance (p = .004), and overall organizational commitment (p < .001). Adequate resources significantly predicted affective (p = .014) and overall commitment (p = .050), while management and leadership predicted normative commitment (p = .016).

CONCLUSION

Nurses' perceptions of their practice environment significantly shape organizational commitment during crisis conditions. Interdisciplinary collaboration consistently emerged as the strongest predictor, underscoring the value of teamwork and nurse–physician partnerships. Adequate staffing and resources also reinforced commitment, particularly in sustaining affective bonds. These findings underscored that supportive practice environments, through collaboration, adequate resources, and participatory leadership, enhance nurses' autonomy and sense of meaningful work, which in turn strengthen organizational commitment, retention, and resilience during crises.

OBJECTIVES: To investigate the effect of age-friendly social and family care environment on the long-term care (LTC) services for the disabled elderly people. METHODS: A questionnaire-based survey was conducted among disabled elderly people in three cities of Zhejiang province from June to August 2022, involving 311 subjects from Ningbo city (LTC service insurance pilot site, insured group) and 542 subjects from Hangzhou and Quzhou cities (uninsured group). The service provisions, including ensuring daily activities, preventive healthcare, and satisfying spiritual comfort, were compared among the groups. The family friendly care environment was evaluated with the Family Function Scale and assistance of daily activities, financial support and emotional comfort. The social friendly care environment was measured with the revised WHO recommended age-friendly city environmental framework, including accessibility guarantee environment, information dissemination environment, social participant environment, and life security environment. After controlling for covariates such as sociodemographic, elderly care status, and health risk characteristics, the impact of environment on the effectiveness of service provision of LTC insurance was explored by multiple logistic regression analysis. The mediating and moderating effects were tested to explore the role of age-friendly care environment. A fixed effects model was used to test the service provision effects of LTC insurance policy. RESULTS: Disabled elderly with LTC insurance had a higher proportion of their preventive health care and spiritual comfort needs met. Additionally, a multifactorial analysis found a significant positive association between LTC insurance and meeting the spiritual comfort needs. Compared with insured group (Ningbo city), disabled elderly people in Hangzhou urban area (OR=0.45, 95%CI:0.27-0.74, P<0.01) and Quzhou rural area (OR=0.21, 95%CI:0.12-0.37, P<0.01) were more likely to feel unsatisfied with spiritual comfort. The results of mediation analysis showed that the scores of accessibility guarantee environment (OR=1.22, 95%CI:1.02-1.45, P<0.05), information dissemination environment (OR=1.19, 95%CI:1.02-1.39, P<0.05), and social participation environment (OR=1.40, 95%CI:1.17-1.67, P<0.01) in a socially friendly care environment were positively correlated with the satisfaction rate of mental comfort services. The results of the moderation effect analysis indicated that a socially friendly care environment (OR=1.46, 95%CI:1.16-1.84, P<0.01) could compensate for the difference in effectiveness between insured (Ningbo) and uninsured (Hangzhou and Quzhou) areas of LTC insurance. A fixed effect model confirmed the policy chain of LTC insurance policy-social friendly care environment-mental health service satisfaction. CONCLUSIONS The implementation of LTC insurance has improved service accessibility, making disabled elderly people feel "seen and valued", and generating psychological and spiritual satisfaction. Accelerating the establishment and improvement of the LTC insurance system requires systematic design, especially emphasizing the supportive role of a socially friendly care environment, and promoting it in urban and rural areas according to the local conditions.

BACKGROUND: To date, results on relationship between CYP3A4 gene polymorphism were limited and inconclusive, and no study focused on the influence of CYP3A4 gene-obesity interaction on breast cancer risk, especially in Chinese women. The purpose of this study was to evaluate the impact of four single nucleotide polymorphisms (SNPs) of CYP3A4 gene, the SNP-SNP and gene-environment interactions on the susceptibility to breast cancer in Chinese women. METHODS: Logistic regression was used to explore the relationship between four SNPs of CYP3A4 gene and the risk of breast cancer. Generalized multifactor dimensionality reduction (GMDR) was used to screen the best SNP-SNP and gene-abdominal obesity interaction combinations among four SNPs and abdominal obesity. Haplotype examination among 4 SNPs was conducted using the SHEsis web-based platform. RESULTS: Logistic regression analysis showed that carriers of rs2242480- T allele have significantly higher breast cancer risk, than those with rs2242480- CC genotype, adjusted OR (95%CI) was 1.68 (1.23-2.16) and 2.03 (1.53-2.58) for participants with CT genotype and TT genotype under additive model. We did not find any notable interactions between the four SNPs within the CYP3A4 gene. GMDR model found a significant association in a two-locus model involving rs2242480 and obesity, with a p-value of 0.018. Stratified analysis found that breast cancer risk was the highest in obese participants with rs2242480- CT or TT genotype, compared to those non-obese participants with rs2242480- CC genotype, OR (95%CI) was 3.02 (1.83-4.25). We found that all haplotype combinations were not correlated with breast cancer risk. CONCLUSIONS We found that the T allele of rs2242480 within the CYP3A4 gene and interaction between rs2242480 and obesity were associated with an increased risk of breast cancer. However, the results of this study were only applicable to the Han ethnic group and cannot be generalized to other ethnic groups in China, and more SNPs of CYP3A4 gene should been enrolled in the analysis in the future, to verify the results obtained in this study.

With the continuous advancement of deep space exploration missions, maintaining astronaut skin health has become a critical medical issue affecting the safety and effectiveness of long-duration missions. Deep space environmental stressors, including microgravity, ionizing radiation, lunar dust exposure, and microbiome dysbiosis, can synergistically disrupt the skin barrier structure, leading to immune homeostasis imbalance and impaired wound healing. In recent years, research on skin protection in deep space has gradually evolved into a systematic "multi-dimensional integrated protective" framework. From the engineering protection perspective, optimization of multi-layer composite spacesuit structures, the use of hydrogen-rich and boron-containing shielding materials, as well as cabin temperature-humidity regulation and debris-resistant technologies, have greatly enhanced environmental defense capacity. From the biomedical protection perspective, functional hydrogels, antimicrobial dressings, and active compounds derived from traditional Chinese medicine have demonstrated remarkable potential in repairing the skin barrier, modulating immunity, and providing antioxidant defense. Meanwhile, the development of skin microecological interventions and wearable physiological monitoring systems has fostered a trend toward personalized health management. Future research should focus on elucidating the interactive mechanisms among the space environment, skin, and immune barrier, while exploring intelligent monitoring and nanotechnology-based protection strategies. Establishing a predictive and preventive skin health safeguarding system will provide comprehensive medical support for future deep space missions.

The unique characteristics of the deep space environment, microgravity, cosmic radiation, and extreme temperature fluctuations, are emerging as major driving forces for pharmaceutical innovation. These factors provide new avenues for optimizing drug formulations, improving crystal structure quality, and accelerating the discovery of therapeutic targets. Advances in deep space research not only help overcome critical bottlenecks in terrestrial drug development but also promote progress in structure-based drug design and deepen understanding of cellular stress-response mechanisms. Current progress in space-based pharmaceutical research primarily includes the study of disease mechanisms under microgravity, protein crystallization in microgravity, and drug development utilizing deep space radiation and resources. However, the operational complexity, high costs, and limited data reproducibility of space experiments remain key challenges hindering widespread application. Looking ahead, with the integration of automation, artificial intelligence analysis, and on-orbit manufacturing, deep space drug development is expected to achieve greater scalability and precision, opening a new frontier in biopharmaceutical science.

BACKGROUND AND OBJECTIVES

The drug problem in the Philippines is influenced by various factors, but research on the specific risk factors and onset of drug use—an early predictor of severe drug abuse—is limited. This crosssectional study aims to identify factors associated with the onset of illicit drug use, focusing on variables such as sex, perceived socioeconomic status, adverse life events (including physical, verbal, and sexual abuse, and bullying), adverse home environments (like family substance abuse and parental separation), and premorbidities (such as anxiety and depression). Understanding these factors is crucial since early drug use often predicts more severe abuse later.

METHODS

This cross-sectional study involved 354 participants aged 7 to 34 years, all undergoing rehabilitation for at least three months. Data were collected through self-administered questionnaires at their rehabilitation centers. Regression analysis was used to examine the relationship between the onset of drug use and the identified risk factors.

RESULTS

Regression analysis revealed that, apart from premorbidities, all the examined factors were significantly correlated with the onset of drug use. Specifically, being male, having higher affluence, experiencing more adverse life events, and living in a more adverse home environment were associated with an earlier onset of drug use. Among these factors, adverse life events and home environment were the strongest predictors of the onset of illicit drug use, while premorbidities did not show a significant relationship with drug use onset.

CONCLUSION

The study highlights that sex, socioeconomic status, adverse life events, and home environment are significant in the early onset of drug use, while premorbidities are not. Early intervention should focus on these key risk factors. A risk-focused approach, guided by biopsychosocial perspectives, is recommended. Targeted interventions should address adverse life events and home environments to prevent early drug use and subsequent abuse effectively.

Environmental damage affects many aspects of healthcare, from extreme weather events to evolving population disease. Singapore's healthcare sector has the world's second highest healthcare emissions per capita, hampering the nation's pledge to reduce emissions by 2030 and achieve net zero emissions by 2050. In this review, we provide an overview of the impact environmental damage has on healthcare, including facilities, supply chain and human health, and examine measures to address healthcare's impact on the environment. Utilising the 'R's of sustainability - rethinking, reducing/refusing, reusing/repurposing/reprocessing, repairing, recycling and research - we have summarised the opportunities and challenges across medical disciplines. Awareness and advocacy to adopt strategies at institutional and individual levels is needed to revolutionise our environmental footprint and improve healthcare sustainability. By leveraging evidence from ongoing trials and integrating sustainable practices, our healthcare system can remain resilient against environment-driven challenges and evolving healthcare demands while minimising further impacts of environmental destruction.

The Remote Home Environment Assessment (RHEA) Framework is a guide designed to help therapists conduct structured home environment assessments remotely using tools and technology. It offers an efficient and practical approach to overcoming the limitations of facility-based home assessments. The framework offers step-by-step procedures for remote home environment assessment for adult clients with physical dysfunction. It involves four major steps that focus on assessing the client’s physical environment: a) screening for selecting the most appropriate remote home environment assessment modality/ies; b) a preparatory phase that includes signing consent forms, explaining the assessment process, and previewing preliminary information; c) administration of the remote assessment; and d) consolidation of the home information. Furthermore, supplementary materials such as screening form, client and health facility consent forms, home evaluation questionnaire and checklist, and client instructions were developed to facilitate and guide the implementing therapist through the aforementioned steps. Pilot testing is recommended to gain accurate and practical insights into the RHEA Framework’s usability and effectiveness.
