RESUMEN

BACKGROUND: People with life-threatening diseases and their family caregivers confront psychosocial and spiritual issues caused by the persons' impending death. Reviews of death education interventions in the context of life-threatening diseases are scarce and limited to certain intervention types. AIMS: This study aims to ascertain existing evidence on death education interventions for the population of adults with advanced diseases and/or their family caregivers and identify gaps for future research. DESIGN: A scoping review guided by Arksey and O'Malley's framework. DATA SOURCES: Thirteen electronic databases were searched for experimental and qualitative studies on death education interventions for the advanced disease population and/or their family caregivers between 1 January 1960 and 25 October 2023. RESULTS: Nine types of interventions were identified in 47 studies, which included 5 qualitative and 42 experimental designs, half of which were pilot and feasibility trials. Most of the studies focused on people with advanced cancer, and only seven investigated caregivers or families/couples. Death-related outcomes were less likely to be assessed relative to psychological outcomes, spiritual well-being, and quality of life. Life review interventions, cognitive-behavior therapy, narrative therapy, and general psychosocial interventions decreased depression and anxiety, but evidence was limited. Factors contributing to the interventions' success included intervention content, which enabled the disclosure of personal experience and death concerns comfortably, trained professionals, and connection to family caregivers. CONCLUSIONS: This work identified a few potentially effective death education interventions for psychological outcomes for people with advanced cancer or their caregivers. Additional trials are needed to confirm the effectiveness of these interventions.

RESUMEN

OBJECTIVE: Although unmet support needs are associated with health-related quality of life (HRQOL) in cancer caregivers, little is known about the mechanism underlying the relationship between two variables. The self-efficacy (SE) theory and literature suggest that caregiving SE is important in the perception of and reaction to caregiving demands, which in turn affects HRQOL. The aim of this study was to examine whether caregiving SE mediates the relationship between unmet support needs and HRQOL in family caregivers of palliative cancer patients. METHODS: This secondary analysis used the data from 125 family caregivers of palliative cancer patients who were recruited from two public hospitals in Hong Kong. The caregivers completed a survey questionnaire that covered socio-demographic characteristics, unmet support needs, caregiving SE, and HRQOL. Parallel mediation analyses were conducted via SPSS PROCESS macro (Model 4) to test the hypothesized models. RESULTS: The direct effect of unmet support needs on mental HRQOL was significant (effect = -0.49, 95% CI = -0.06 to -0.92). For the indirect effect, only caregiving SE in the domain of 'care for the care recipient' mediated the relationship between unmet support needs and mental HRQOL (effect = -0.32, 95% CI = -0.08 to -0.59). CONCLUSION: The findings suggest that caregiving SE may function as a mechanism through which unmet support needs influence mental HRQOL in family caregivers of palliative cancer patients. Healthcare providers should consider developing supportive care interventions to improve caregivers' HRQOL by incorporating effective strategies to enhance SE and reduce unmet needs for this population.

RESUMEN

This study aimed to describe and compare end-of-life care and decision-making preferences among Chinese community-dwelling older adults between Wuhan and Hong Kong in China. The study adopted a cross-sectional correlation design and recruited a convenience sample of 259 older adults, aged ≥65 years old from five community centers in Wuhan and Hong Kong. Participants completed a validated structured questionnaire that measured their end-of-life care and decision-making preferences. Multivariate logistic regression analyses were conducted. Results showed that Wuhan participants were significantly more likely to view "trying every means to extend the life span" as very important/important; and they perceived "support from religious personnel" as unimportant/very unimportant. Different from those older adults in Hong Kong, the Wuhan participants significantly chose their home as the preferred place for end-of-life care and death. They also tended to prefer family members to enact the decision-maker role in end-of-life decision situations. The study suggests older adults in Hong Kong and Wuhan have some differences in preferences for end-of-life care and decision-making, which provides the basis for future development of culturally relevant community-based end-of-life care.

RESUMEN

PURPOSE: While the existing knowledge base on the impact of prostate cancer (PC) and its treatment on sexuality and intimacy has been generated from Western populations, there is a lack of such evidence in the Asian context. This study aimed to explore men's experiences of sex and intimacy after PC treatment in China. METHODS: This study adopted an interpretive descriptive design. Using purposive sampling, 13 PC patients were selected from a urology outpatient unit of a hospital in South China and proceeded with individual semi-structured telephone interviews. Each interview was transcribed verbatim and analyzed using constant comparison analysis. RESULTS: Four themes emerged from the interview data, including (a) encountering altered sexuality, (b) communication and sexual adjustments, (c) maintenance of quality intimate relationship, and (d) lack of sexual health support. CONCLUSIONS: The findings revealed that PC treatment significantly impaired patients' sexual functions, and their sexual health needs were mainly unmet by healthcare providers. There is a great need to design culturally relevant interventions to improve sexual health among this population.

RESUMEN

OBJECTIVE: This study aimed to systematically identify and synthesize evidence on the feasibility, acceptability, and effects of behavior change interventions for improving multiple dietary behaviors among cancer survivors. METHODS: A total of 14 electronic databases and three trial registries were searched. Experimental studies that examined the feasibility, acceptability, and effects of behavior change interventions for improving multiple dietary behaviors among cancer survivors and published in English or Chinese peer-reviewed journals or protocols were considered eligible. The methodological quality of the included studies was evaluated using the revised Cochrane risk-of-bias assessment tool. Data were extracted and synthesized narratively. RESULTS: Six studies, with a sample size ranging from 50 to 3088, were included. The studies had a high overall risk of bias. Six studies reported feasibility data, and the average eligibility, recruitment, and retention rates at post-intervention were 60.7%, 66.7%, and 90.7%, respectively. Only one study measured the acceptability and reported that 66.6% of participants were satisfied with the intervention. Five out of the six studies that measured fruit and vegetable consumption reported statistically significant positive intervention effects. Two studies reported inconsistent intervention effects on wholegrain consumption. Only one study measured the consumption of processed meat, sugar, and alcohol, which had statistically nonsignificant intervention effect. CONCLUSIONS: Behavior change interventions for improving multiple dietary behaviors might be feasible and effective to increase fruit and/or vegetable consumption among cancer survivors. Further research is needed to examine the acceptability and effects of the intervention for modifying other dietary behavior.

RESUMEN

OBJECTIVE: This study aimed to examine the previous uptake of cervical cancer screening and intention to be screened and its associated factors among women living with HIV in China. METHODS: We conducted a cross-sectional survey of 213 women living with HIV to collect information about cervical cancer screening behaviour, demographics, knowledge about cervical cancer and screening, and perception of HIV symptom severity. RESULTS: Seventy-eight women living with HIV (36.6%) had undergone cervical cancer screening, and 83 (61.5%) of the nonscreened women had the intention to be screened in the future. Using multivariate analysis, women who had more knowledge about cervical cancer screening (OR = 2.373, 95% CI = 1.593-3.534, p = 0.000) and had at least one nongynecological symptom (OR = 0.446, 95% CI = 0.204-0.978, p = 0.044) were more likely to have received screening previously. CONCLUSION: This study emphasised that knowledge, as a salient factor, was crucial to promoting cervical cancer screening behaviour among women living with HIV. Effective measures should be taken to promote the knowledge about cervical cancer prevention. A new healthcare model, including preventive healthcare in addition to HIV/AIDS care, may be needed to address the complex needs of women living with HIV in China.

RESUMEN

Breastfeeding is an integral part of early childhood interventions as it can prevent serious childhood and maternal illnesses. For breastfeeding support programmes to be effective, a better understanding of contextual factors that influence women's engagement and satisfaction with these programmes is needed. The aim of this synthesis is to suggest strategies to increase the level of satisfaction with support programmes and to better match the expectations and needs of women. We systematically searched for studies that used qualitative methods for data collection and analysis and that focused on women's experiences and perceptions regarding breastfeeding support programmes. We applied a maximum variation purposive sampling strategy and used thematic analysis. We assessed the methodological quality of the studies using a modified version of the CASP tool and assessed our confidence in the findings using the GRADE-CERQual approach. We included 51 studies of which we sampled 22 for in-depth analysis. Our sampled studies described the experiences of women with formal breastfeeding support by health care professionals in a hospital setting and informal support as for instance from community support groups. Our findings illustrate that the current models of breastfeeding support are dependent on a variety of contextual factors encouraging and supporting women to initiate and continue breastfeeding. They further highlight the relevance of providing different forms of support based on socio-cultural norms and personal backgrounds of women, especially if the support is one-on-one. Feeding decisions of women are situated within a woman's personal situation and may require diverse forms of support.

RESUMEN

Trigeminal neuralgia is a severe neuropathic disorder, affecting the distribution area of the trigeminal nerve and often impairs the quality of life of patients. More and more scholars agree that one of the pathogenesis of trigeminal neuralgia is due to the demyelinating lesion caused by vascular compression or arachnoid bundle wrapping on the root exit zone of trigeminal nerve. In this regard, the most effective method is microvascular decompression, which can relieve the compression of the offending vessels and the thickened arachnoid on the trigeminal nerve. However, it still has some disadvantages, such as the possibility of fatal complications. In recent years, with the advancement of neurosurgical treatment technology, new progress has been made in microvascular decompression. This article mainly introduces the surgical techniques and new methods of the microvascular decompression.

RESUMEN

BACKGROUND: Among the few existing needs assessment tools for family carers, the 14-item Carer Support Needs Assessment Tool (CSNAT) is the only brief and holistic needs screening tool designed for everyday use in palliative care practices. The aim of this study was to evaluate the reliability, validity, and acceptability of the traditional Chinese version of the CSNAT in palliative care settings in Hong Kong. METHODS: This adopted a cross-sectional and correlation design with repeated measures. The participants were 125 family carers of palliative cancer patients and 10 healthcare providers (HCPs) that were recruited from two local hospitals. The evaluation of psychometric properties included the following: (1) content validity through HCPs including frontline physicians, nurses, social workers, and clinical psychologists; (2) construct validity between the CSNAT items and those of the validated tools that measured caregiver burden, social support, and caregiving self-efficacy; and (3) one-week test-retest reliability in a sub-sample of 81 caregivers. The acceptability of the tool was assessed by the carers using several closed-ended questions. RESULTS: The content validity index of the CSNAT at the scale level was 0.98. Each item of the CSNAT was significantly and moderately correlated with caregiver burden (Spearman's r = 0.24 to 0.50) and caregiving self-efficacy (r = - 0.21 to - 0.52), but not for social support. All CSNAT items had fair to moderate test-retest reliability (weighted kappa = 0.21 to 0.48), with the exception of two items "managing your relatives' symptoms, including giving medicines" and "having time for yourself in the day". Regarding the acceptability of the CSNAT, almost all HCPs were willing to use the CSNAT for carer assessment and support. 89.6% of the carers demonstrated a comprehensibility of the CSNAT tool and 92.9% felt comfortable answering the questions. Around 90% of the carers agreed to use the tool for screening, discussing needs, and making referrals. CONCLUSION: The traditional Chinese version of the CSNAT is a tool with high validity and acceptability and adequate reliability that measures family carers' support needs, which should be considered for wide application in local palliative care practices.

RESUMEN

Previous studies have reported that miRNAs are involved in the progression of glioma, and that miR-27b-3p is involved in a variety of cancers. However, whether miR-27b-3p has a role in glioma is still unknown. Here, we demonstrated that miR-27b-3p is downregulated in glioma, and this is associated with the development of glioma. Overexpression of miR-27b-3p in glioma cells inhibits cell proliferation and migration, and induces cell apoptosis, which suppresses the progression of glioma. Furthermore, in our study, overexpression of miR-27b-3p also inhibited the growth of xenografted glioma tumors in-vivo. Finally, we verified that Yes Associated Protein 1 (YAP1) is the downstream target of miR-27b-3p, and that miR-27b-3p controls the proliferation, migration, and apoptosis of glioma cells via regulating YAP1. Our study reveals a novel mechanism through which miR-27b-3p functions in the development of glioma, and thus provides a potential therapeutic target for the treatment of glioma.

RESUMEN

High-resolution mass spectrometry (HRMS) is an important technology for studying biotransformations of drugs in biological systems. In order to process complex HRMS data, bioinformatics, including data-mining techniques for identifying drug metabolites from liquid chromatography/high-resolution mass spectrometry (LC/HRMS) or multistage mass spectrometry (MSn ) datasets as well as elucidating the detected metabolites' structure by spectral interpretation software, are important tools. Data-mining technologies have widely been used in drug metabolite identification, including mass defect filters, product ion filters, neutral-loss filters, control sample comparisons and extracted ion chromatographic analysis. However, the metabolites identified by current different technologies are not the same, indicating the importance of technique integration for efficient and complete identification of metabolic products. In this study, a universal, high-throughput workflow for identifying and verifying metabolites by applying the drug metabolite identification software UNIFI is reported, to study the biotransformation of verapamil in rats. A total of 71 verapamil metabolites were found in rat plasma, urine and faeces, including two metabolites that have not been reported in the literature. Phase I metabolites of verapamil were identified as N-demethylation, O-demethylation, N-dealkylation and oxidation and dehydrogenation metabolites; phase II metabolites were mainly glucuronidation and sulfate conjugates, indicating that UNIFI software could be effective and valuable in identifying drug metabolites.

RESUMEN

This study aimed to translate the Perspectives on Caring for Older Patients scale into Chinese, both the full and the shortened versions, and test its psychometric properties among Chinese nursing students. In this methodological research, the scale were translated and administered to 307 nursing students recruited from two universities in mainland China. The psychometric testing mainly included internal consistency reliability using Cronbach's alphas, 2-week test-retest reliability using the intraclass correlation coefficient, convergent validity with Kogan's Attitude toward Older People scale, and factorial validity using exploratory factor analysis. Cronbach's alphas for the full and the shortened version scales were 0.77 and 0.75, respectively. The intraclass correlation coefficient values of both versions exceeded 0.70 and their scores were moderately correlated with the Kogan's Attitude toward Older People scale's scores. While exploratory factor analyses revealed a six-factor structure for the full version with factor loadings of five items below 0.3, the shortened version identified two factors with all factor loadings above 0.3. This study concluded that the psychometric properties of the full version scale were adequate and similar to those of the shortened version except for factorial validity.

RESUMEN

BACKGROUND: In China, cervical cancer cases are increasing, making an impact on the worldwide burden of cervical cancer. Despite the initiatives undertaken by the Chinese government, the current coverage of cervical screening in China remains suboptimal. There is an urgent need to identify the facilitators and barriers associated with the uptake of cervical cancer screening among the Chinese population. PURPOSE: The study aimed to explore the experiences and perceptions of cervical cancer screening of mainland Chinese women in relation to their screening behaviour, particularly in the aspects of health care system and health profession roles. METHODS: A qualitative research was conducted using semi-structured interviews. A total of 27 Chinese women aged 25 to 50 (both screened and non-screened women) completed the interviews. The analysis of the interview data was undertaken inductively using latent content analysis. DISCUSSION AND CONCLUSION: Results showed that organised health examination programmes provide a good basis for integrating cervical screening into broader checks on the health of women, and utilising different networks of social support facilitate the utilisation of the screening service. However, education on cervical cancer and screening must be made more generally available. More importantly, there is a need for a more participatory and empowering exchange in the encounter between health professions and these women. Appropriate training program is strongly recommended for health professions about communicate skills with patients. Future work should focus on identifying strategies to overcome the barriers to cervical screening related to health care system and medical professions among this population.

RESUMEN

In this study, we investigated the anticancer potentials of Rhein, an anthraquinone derivative of most commonly used Chinese rhubarb on the rat F98 glioma cells. The experimental studies revealed that Rhein induced cell cycle arrest, caspase mediated apoptosis. It results in the formation of intracellular acidic vesicles in cytoplasm, leading to autophagy. Differentiation of viable cells towards elongation of matured astrocytes was proved by monitoring dramatic changes in morphological characteristics as well as identified from the elevation of glial fibrillary acidic protein (GFAP) expression. Rhein treatment did not alter the phosphorylated MAPKs activation including p-38, JNK and NF-κB, transcription unit whereas rhein significantly inhibited ERK1/2 activation in F98 glioma cells. PD98059, a specific inhibitor for ERK activation imitates rhein effects on morphology and expressions of GFAP but did not help to induce any apoptosis or autophagy. Collective data exhibited that potentials of rhein in anti-cancer property in ERK-independent apoptosis and autophagy in association with downregulated ERK-dependent differentiation process of glioma cell lines.

RESUMEN

BACKGROUND: With increasing awareness in the chronic nature of cancer, promoting the engagement of breast cancer survivors in self-management has become a priority of cancer care reform initiatives. This study aimed to reveal Chinese breast cancer survivors' views and experiences of self-management in extended survivorship. METHODS: Archived interview transcripts from 19 breast cancer survivors (<5 years since diagnosis) were subjected to a secondary analysis. Each transcript was re-examined through qualitative content analysis. RESULTS: Three categories were established to represent the perceptions of the participants on their self-management tasks related to health and well-being, emotions, and roles and relationships. Managing health and well-being covers modifying lifestyle, taking traditional Chinese medicine, attending regular follow-ups, managing symptoms, and adhering to hormonal therapy. Managing emotions involves maintaining a positive attitude and utilizing supportive resources. Managing roles and relationships comprises adjusting to life as cancer survivors, maintaining marital relationships, and performing familial and other social roles. CONCLUSIONS: Most participants actively participated in various self-management tasks and behaviors that can help improve their health and prevent cancer recurrence. They may exhibit optimal self-management in their emotions and most health aspects but may exert limited efforts in managing their different roles during survivorship.

RESUMEN

PURPOSE: Although we acknowledge the negative and positive aspects of the cancer survivorship experience, we have little information on this issue from the perspective of Chinese breast cancer survivors. This study aimed to explore the perceptions of negative and positive life changes following treatment completion among this population. METHODS: Using purposive sampling, 29 breast cancer survivors were selected from the attendees of a local cancer self-help organization in middle China and proceeded with semi-structured in-depth interviews. Each interview was transcribed verbatim and analyzed using directed content analysis. RESULTS: Two predetermined categories were identified to represent participant perception of the breast cancer survivorship experience, namely, negative life changes and positive life changes. The first category included fear of recurrence, symptom experience, poor body image, altered sexuality and intimacy, and financial burden. The second category consisted of new life perspective, personal growth, and enhanced relationships with family. CONCLUSIONS: Our findings contribute to the emerging evidence on the duality of breast cancer survivorship. This enhanced understanding of the specific negative and positive changes experienced by Chinese breast cancer survivors can assist health professionals in addressing survivorship issues by designing appropriate interventions to minimize negative consequences and enhance positive growth.

RESUMEN

Quality of life (QOL) in cancer survivorship is a multidimensional and subjective concept, which represents the personal sense of the physical, psychological, social, and spiritual consequences of cancer diagnosis and its treatment. This mixed method study aimed to explore the QOL of Chinese breast cancer survivors. Participants were recruited from a cancer self-help organization in the central area of China. QOL was assessed using the QOL-Cancer Survivor Scale and subsequently elicited by in-depth interviews. Results showed that participants had good overall QOL but with unfavorable aspects in psychological and social well-being. Interview data revealed that participants seldom attended spiritual activities. Instead, they actively reconnected with their "self" to create a positive meaning from their cancer experience. Understanding how Chinese breast cancer survivors perceive QOL is important for health professionals to address survivorship in this population.

RESUMEN

BACKGROUND: Bullet-induced brain wounds are common among military personnel in war zones and among civilians with gun accidents or crime-related gun injuries. The goal of this study was to develop a nonfatal porcine model of penetrating craniocerebral gunshot wound (PCGW) by firing a projectile in live swine to induce PCGW in such a realistic manner as to reconstruct their physical characteristics. MATERIALS AND METHODS: We established a nonfatal porcine model of PCGW based on a custom-designed experimental gun that emulates the shooting of a 5.56-mm NATO standard rifle at 800 m (317 m/s; 200.9 J). Commercial swine (n = 20) were subjected to a ballistic wound to the bilateral frontal lobe, and four swine were used as controls. Surviving swine were used in subsequent first-aid, management, and monitoring experiments for neurosurgeons. Various physiological variables were measured continuously. After computed tomography (CT) scanning and three-dimensional CT reconstructions, all pigs underwent primary lifesaving emergency interventions, including emergency decompressive craniotomies and hemorrhage control. RESULTS: In our nonfatal porcine model of PCGW, injuries were comparable in their morphology to real gunshot wounds, as evidenced by analysis of wound characteristics and CT scan images. The survival rates of the pigs were 100% within 2 h, 95% within 6 h, 85% within 12 h, and 85% within 24 h (P < 0.01). Hemodynamics, hematology, blood routine biochemistry, coagulation, and other physiological parameters also exhibited significant changes in the PCGW pigs. CONCLUSIONS: This model makes possible the laboratory reproduction of real ballistic wounds in a live large animal model that is close to humans.

RESUMEN

This study assessed previous research aimed at mitigating the adverse effects of freeze-thawing on meat quality. Specifically, it focuses on assessing the physicochemical alterations in meat resulting from freezing, freeze-thawing, or technologies to minimize these alterations. Recent studies have focused on conventional freeze-thaw technology applicable across various livestock species and muscle types. However, recent research has indicated the necessity for developing freeze-thaw technology considering the unique characteristics of individual muscles. In this review, we summarize previous studies that have compared alterations in the physicochemical properties of primary muscles owing to freezing or freeze-thawing. Despite the introduction of various technologies to significantly reduce the adverse effects on meat quality resulting from freeze-thawing, it is essential to consider the unique characteristics (proximate composition, pH, and muscle fiber characteristics) of individual muscles or cuts to develop enhanced the freeze-thaw processing technology.

RESUMEN

Meat derived from skeletal muscles of animals is a highly nutritious type of food, and different meat types differ in nutritional, sensory, and quality properties. This study was conducted to compare the results of previous studies on the muscle fiber characteristics of major porcine skeletal muscles to the end of providing basic data for understanding differences in physicochemical and nutritional properties between different porcine muscle types (or meat cuts). Specifically, the muscle fiber characteristics between 19 major porcine skeletal muscles were compared. The muscle fibers that constitute porcine skeletal muscle can be classified into several types based on their contractile and metabolic characteristics. In addition, the muscle fiber characteristics, including size, composition, and density, of each muscle type were investigated and a technology based on these muscle fiber characteristics for improving meat quality or preventing quality deterioration was briefly discussed. This comparative review revealed that differences in muscle fiber characteristics are primarily responsible for the differences in quality between pork cuts (muscle types) and also suggested that data on muscle fiber characteristics can be used to develop optimal meat storage and packaging technologies for each meat cut (or muscle type).
