RESUMO

PURPOSE: Patients with gynaecological cancer often experience psychological issues due to multiple stressors. Psychological disturbances have debilitating effects on patients with gynaecological cancer. In recent decades, digital psychosocial interventions have rapidly advanced and been incorporated into mental health interventions. Digital psychosocial interventions could provide patients with several benefits over traditional in-person interventions, including convenience, anonymity, flexible scheduling, and geographic mobility. The aim of this systematic review was to synthesize the effectiveness of digital psychosocial intervention in reducing psychological distress, depression, and anxiety and improving health-related quality of life in patients with gynaecological cancer. METHODS: Three-step extensive search was performed on 22 December 2022 from nine bibliographic databases, trial registries and grey literature. Experimental studies involving patients with gynaecological cancer utilizing digital psychosocial interventions for the improvement of mental health outcomes were included. Meta-analysis was conducted using RevMan 5.4 software. Heterogeneity was analysed by Cochran's Q test and I2. Subgroup analyses were attempted to evaluate relative effect sizes of subgroup features. RESULTS: Meta-analysis of nine studies revealed small effect size in reduction of depression post-intervention (d = 0.24, 95% CI - 0.46 to - 0.02) and medium effect size in reduction of psychological distress post-intervention (d = 0.51, 95% CI - 0.81 to - 0.21) and follow-up (d = 0.65, 95% CI - 1.25 to - 0.05) compared to the control group. The effects of digital psychosocial interventions on anxiety and health-related quality of life were not statistically significant. CONCLUSIONS: Digital psychosocial interventions probably reduced psychological distress and slightly reduced depression amongst patients with gynaecological cancer compared to the control group, which can be integrated into clinical practice. Additional trials with rigorous methodology and bigger sample sizes are needed to validate findings. TRIAL REGISTRATION: PROSPERO (CRD42023389502).

RESUMO

BACKGROUND: Spinal disorders are highly prevalent worldwide with high socioeconomic costs. This cost is associated with the demand for treatment and productivity loss, prompting the exploration of technologies to improve patient outcomes. Clinical decision support systems (CDSSs) are computerized systems that are increasingly used to facilitate safe and efficient health care. Their applications range in depth and can be found across health care specialties. OBJECTIVE: This scoping review aims to explore the use of CDSSs in patients with spinal disorders. METHODS: We used the Joanna Briggs Institute methodological guidance for this scoping review and reported according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) statement. Databases, including PubMed, Embase, Cochrane, CINAHL, Web of Science, Scopus, ProQuest, and PsycINFO, were searched from inception until October 11, 2022. The included studies examined the use of digitalized CDSSs in patients with spinal disorders. RESULTS: A total of 4 major CDSS functions were identified from 31 studies: preventing unnecessary imaging (n=8, 26%), aiding diagnosis (n=6, 19%), aiding prognosis (n=11, 35%), and recommending treatment options (n=6, 20%). Most studies used the knowledge-based system. Logistic regression was the most commonly used method, followed by decision tree algorithms. The use of CDSSs to aid in the management of spinal disorders was generally accepted over the threat to physicians' clinical decision-making autonomy. CONCLUSIONS: Although the effectiveness was frequently evaluated by examining the agreement between the decisions made by the CDSSs and the health care providers, comparing the CDSS recommendations with actual clinical outcomes would be preferable. In addition, future studies on CDSS development should focus on system integration, considering end user's needs and preferences, and external validation and impact studies to assess effectiveness and generalizability.

RESUMO

INTRODUCTION: Nurses, assuming a wide range of clinical and patient care responsibilities in a healthcare team, are highly susceptible to direct and indirect exposure to traumatic experiences. However, literature has shown that nurses with certain traits developed a new sense of personal strength in the face of adversity, known as post-traumatic growth (PTG). This review aimed to synthesize the best available evidence to evaluate personal and work-related factors associated with PTG among nurses. DESIGN: Mixed studies systematic review. METHODS: Studies examining factors influencing PTG on certified nurses from all healthcare facilities were included. Published and unpublished studies were identified by searching 12 databases from their inception until 4th February 2023. Two reviewers independently screened, appraised, piloted a data collection form, and extracted relevant data. Meta-summary, meta-synthesis, meta-analysis, as well as subgroup and sensitivity analyses were performed. Integration of results followed result-based convergent design. RESULTS: A total of 98 studies with 29,706 nurses from 18 countries were included. These included 49 quantitative, 42 qualitative, and seven mixed-methods studies. Forty-six influencing factors were meta-analyzed, whereas nine facilitating factors were meta-summarized. A PTG conceptual map was created. Four constructs emerged from the integration synthesis: (a) personal system, (b) work-related system, (c) event-related factors, and (d) cognitive transformation. CONCLUSION: The review findings highlighted areas healthcare organizations could do to facilitate PTG in nurses. Practical implications include developing intervention programs based on PTG facilitators. Further research should examine the trend of PTG and its dynamic response to different nursing factors. CLINICAL RELEVANCE: Research on trauma-focused therapies targeting nurses' mental health is lacking. Therefore, findings from this review could inform healthcare organizations on the PTG phenomenon and developing support measures for nurses through healthcare policies and clinical practice.

RESUMO

In this study, we examined the effects of rumen-protected L-tryptophan supplementation on the productivity and physiological metabolic indicators in lactating Holstein cows under heat stress conditions. The study involved eight early lactating Holstein cows (days in milk = 40 ± 9 days; milk yield 30 ± 1.5 kg/day; parity 1.09 ± 0.05, p < 0.05), four cows per experiment, with environmentally controlled chambers. In each experiment, two distinct heat stress conditions were created: a low-temperature and low-humidity (LTLH) condition at 25 °C with 35-50% humidity and a high-temperature and high-humidity (HTHH) condition at 31 °C with 80-95% humidity. During the adaptation phase, the cows were subjected to LTLH and HTHH conditions for 3 days. This was followed by a 4-day heat stress phase and then by a 7-day phase of heat stress, which were complemented by supplementation with rumen-protected L-tryptophan (ACT). The findings revealed that supplementation with ACT increased dry matter intake as well as milk yield and protein and decreased water intake, heart rate, and rectal temperature in the HTHH group (p < 0.05). For plateletcrit (PCT, p = 0.0600), the eosinophil percentage (EOS, p = 0.0880) showed a tendency to be lower, while the monocyte (MONO) and large unstained cells (LUC) amounts were increased in both groups (p < 0.05). Albumin and glucose levels were lower in the HTHH group (p < 0.05). The gene expressions of heat shock proteins 70 and 90 in the peripheral blood mononuclear cells were higher in the ACT group (HTHH, p < 0.05). These results suggest that ACT supplementation improved productivity, physiological indicators, blood characteristics, and gene expression in the peripheral blood mononuclear cells of early lactating Holstein cows under heat-stress conditions. In particular, ACT supplementation objectively relieved stress in these animals, suggesting that L-tryptophan has potential as a viable solution for combating heat-stress-induced effects on the cattle in dairy farming.

RESUMO

AIM: This study examined the correlation among turnover intention, emotional intelligence and job burnout in male nurses and determined its influencing factors. BACKGROUND: The number of male nurses has increased in China; however, the turnover rate is very high. Nurses' turnover intention is related to job burnout and emotional intelligence. INTRODUCTION: Recent studies have shown that job burnout and emotional intelligence are related to medical and health institution employees' intention to leave their jobs. It is not clear if the same conclusions can be drawn about male nurses. METHODS: For this cross-sectional study, 627 male nurses were recruited from across China between May and July 2018. Data were collected through an online questionnaire, and Pearson's product-moment correlation coefficient and multiple linear regression were performed to analyse the data. RESULTS: There was a weak negative, moderate positive and moderate negative correlation between turnover intention and emotional intelligence, turnover intention and job burnout, and emotional intelligence and job burnout, respectively. Factors that significantly affected turnover intention among male nurses included job burnout, young age, lack of interest in nursing and working in the emergency department. CONCLUSION: The study revealed the factors that affected male nurses' turnover intention and the relationships between turnover intention, emotional intelligence and job burnout. IMPLICATIONS FOR NURSING MANAGEMENT AND SOCIAL POLICY: Hospital managers should provide necessary help and support to reduce male nurse turnover rates and incorporate emotional intelligence training. The policy should eliminate the unfair college admission practices for students choosing nursing majors, raise the nursing profession's salaries and vigorously develop specialty nursing. In addition, diversified values should be promoted, and stereotypes of male nurses in nursing should be broken.

RESUMO

Fenbendazole (FBZ) has been safely used as an antiparasitic agent in animals for decades, and the anticancer effects of FBZ have been studied through various mechanisms. However, there is a lack of in vivo studies that include lymphoma. Therefore, this study examined the effects of FBZ on EL-4 cells and a mouse T lymphoma model. FBZ induced G2/M phase arrest in EL-4 cells, resulting in cell death and decreased metabolic activity. However, FBZ had no anticancer effects on an EL-4 mouse lymphoma model in vivo, as evident by rapid weight loss and tumor growth comparable to the control. The FBZ-treated EL-4 cells expressed higher levels of PD-L1 and CD86, which are associated with T cell immunity in the tumor microenvironment (TME), than the controls. Furthermore, the hematoxylin and eosin staining of the FBZ-treated tumor tissues showed a starry sky pattern, which is seen in actively proliferating cancer tissues, and an immunohistochemical analysis revealed a high percentage of immunosuppressive M2 macrophages. These changes in the immune activity in the TME contradict the results of the in vitro experiments, and further studies are needed to determine the detailed mechanisms by which FBZ induces these responses.

RESUMO

Excessive endogenous or exogenous levels of the stress hormone cortisol have negative effects on various tissues, including the skin. Iris pallida (IP), used in traditional medicine and perfumes, exhibits biological activities, such as antioxidant and anti-inflammatory activities. In this study, we aimed to investigate the inhibitory effect of IP extract (IPE) on cortisol activity in human skin cells. We found that IPE alleviated the cortisol-induced decrease in the levels of procollagen type 1 and hyaluronic acid (HA), which were significantly recovered by 106% and 31%, respectively, compared with cortisol-induced reductions. IPE also rescued the suppression of the gene expression of COL1A1 and the HA synthases HAS2 and HAS3 in cortisol-exposed cells. Moreover, IPE blocked the cortisol-induced translocation of the glucocorticoid receptor (GR) from the cytoplasm to the nucleus as effectively as the GR inhibitor mifepristone. Analysis using a high-performance liquid chromatography-diode-array detector system revealed that irigenin, an isoflavone, is the main component of IPE, which restored the cortisol-induced reduction in collagen type 1 levels by 82% relative to the cortisol-induced decrease. Our results suggest that IPE can act as an inhibitor of cortisol in human skin cells, preventing cortisol-induced collagen and HA degradation by blocking the nuclear translocation of the GR. Therefore, IPE may be used as a cosmetic material or herbal medicine to treat stress-related skin changes.

RESUMO

Food parenting practices, especially Autonomy Support practices and Structure practices, have not been comprehensively studied among parents of children born with low birth weight in Asia. The aim of this study was to investigate food parenting practices among parents of preschoolers who were born with low (<2500 g) and normal birth weight (≥2500 g) in Singapore. We recruited 197 parents of pre-school children (aged 3-5 years) who completed a socio-demographic questionnaire and the HomeSTEAD questionnaire, which examined food parenting practices. Among parents, 98 (49.8%) and 99 (50.2%) had children who were normal (NBW) and low birth weight (LBW) respectively. Parents of children with LBW had lower scores in one Autonomy Support practice (Encouragement) and three Structure practices (Meal setting, Planning and preparation of healthy meals, Rules and limits around unhealthy foods), after controlling for ethnicity and parental education. Parents of children with LBW also scored higher in one Autonomy Support practice (Guided choices: when food is given). There were no significant differences in Coercive Control practices between parents of both groups. Healthcare professionals could use this information to assess parental needs when facilitating parents' positive food parenting practices, especially among children with low birth weight.

RESUMO

BACKGROUND: Day surgery allows families to return home quickly. Only a few approaches to preparing for day surgery have demonstrated how digital solutions can support families and children. OBJECTIVE: This study aims to evaluate the effectiveness of a mobile app intervention on preschool children's fear and pain and parents' anxiety and stress in preparing children for day surgery. METHODS: This study was conducted at the Pediatric Day Surgical Department of a university hospital in Finland between 2018 and 2020. Parents of children (aged 2-6 y) who were in a queue for elective day surgery were randomized into the intervention group (IG; n=36) and control group (CG; n=34). The CG received routine preparations, whereas the IG was prepared using a mobile app. Parents' and children's outcomes were measured using validated scales at 4 different points: at home (T1 and T4) and at the hospital (T2 and T3) before and after surgery. Group differences were analyzed using statistical methods suitable for the material. RESULTS: Before surgery, parents in both groups experienced mild anxiety, which decreased after surgery. Parental anxiety did not differ between groups preoperatively (P=.78) or postoperatively (P=.63). Both groups had less anxiety at home after surgery compared with before. The IG showed a significant decrease (P=.003); the CG also improved (P=.002). Preoperatively at home, most parents in both groups experienced no stress or mild stress (P=.61). Preoperatively at the hospital, parents in both groups experienced mild stress; however, parents in the IG experienced more stress during this phase (P=.02). Parents in the IG experienced significantly less stress postoperatively than those in the CG (P=.05). Both groups showed decreased stress levels from before to after surgery (IG: P=.003; CG: P=.004) within each group. There were no significant differences in children's pain levels between the groups and measurement points. This was observed before surgery at home (P=.25), before surgery at the hospital (P=.98), and after surgery at the hospital (P=.72). Children's fear decreased more in the IG (P=.006) than in the CG (P=.44) comparing the phases before and after surgery at home. Fear did not differ between the IG and CG preoperatively at home (P=.20) or at the hospital (P=.59) or postoperatively at the hospital (P=.62) or at home (P=.81). CONCLUSIONS: The mobile app intervention did not reduce anxiety or pain. However, it was observed that parents in the IG experienced substantially heightened stress levels before surgery at the hospital, which decreased significantly after surgery at home. In addition, fear levels in children in the IG decreased over time, whereas no significant change was observed in the CG. These results are important for developing health care service chains and providing families with innovative and customer-oriented preparation methods.

RESUMO

This study investigated the effects of dietary energy levels on growth, blood metabolites, and stress biomarkers in Korean native calves subjected to heat stress (HS). Twenty-four calves (BW: 221.5 ± 24.9 kg; age: 162 ± 4.8 d) were randomly housed in climate-controlled chambers using 3 × 2 factorial design. There were three treatment groups including low energy (LE = 2.53), medium energy (ME = 2.63), and high energy levels (HE = 2.72 Mcal/kg of DM) and two stress levels (threshold: THI = 70-73; severe: THI = 89-91). The calves were adapted to 22 °C for 7 days, then to the target THI level for 14 days. Energy intake, average daily gain, and gain to feed ratio were determined to decline (p < 0.05) under severe HS compared with threshold. Under severe HS, rectal temperature was increased 0.67 °C compared with threshold. Severe HS increased glycine, ammonia, and 3-methylhistidine concentrations compared with threshold (p < 0.05). Gluconeogenic AAs in the blood were increased among the various energy levels regardless of HS. In PBMCs the expression of HSP70 gene was increased in the LE group (p < 0.05), and the HSP90 gene expression was increased in LE and ME groups (p < 0.05) under severe HS. However, the expression of genes HSP70 and HSP90 in HE group did not differ under severe HS (p > 0.05). It has been suggested that HE intake may have a beneficial effect on PBMCs by mitigating ATP depletion. No differences in growth performance were found when increasing energy intake with high protein (CP 17.5%) under HS. However, the increase in energy levels resulted in increased gluconeogenic AAs but decreased urea and 3-methylhistidine in blood. In conclusion, increased energy levels are thought to improve HS adaptability by inhibiting muscle degradation and glucose production using gluconeogenic AAs in Korea native calves under HS condition.

RESUMO

PURPOSE: To evaluate the effects of the Parent-Child Sandplay Therapy (PCST) Program on autism behaviors, social responsiveness and sleep quality among preschool children with autism spectrum disorder (ASD), and their mothers' parenting stress. DESIGN AND METHODS: A prospective, randomized controlled, parallel-group trial was employed. Fifty-two child-mother dyads were randomly assigned to an intervention group (n = 26) or a control group (n = 26) from February 2017 to February 2019. The intervention group was treated with a 20-week PCST Program plus an Applied Behavior Analysis-based program (ABA-based program), whereas the control group received only the ABA-based program. Outcome measures included the Autism Behavior Checklist total scores, Social Responsiveness Scale scores, Children's Sleep Habits Questionnaire scores, and Parenting Stress Index-Short Form scores, measured at baseline, post-intervention (20 weeks after baseline) and follow-up assessments (32 weeks after baseline). RESULTS: Finally, 43 dyads completed the study. The linear mixed model analysis resulted in a significant group*time interaction effect of ABC score (Est = 2.027, t = 3.277; p < 0.01), SRS score (Est = 3.377, t = 6.095; p < 0.01), PSI-SF score (Est = 3.873, t = 4.253, p < 0.01), and CSHQ score (Est = 3.158, t = 6.485; p < 0.05). CONCLUSION: Our findings suggested that the PCST Program could potentially improve social interaction and sleep quality of preschool children with ASD while decreasing parenting stress. PRACTICE IMPLICATIONS: The PCST Program was found to be a feasible and a promising treatment for children with mild-to-moderate ASD as well as for their parents. It was a nurse-led program, which could be integrated into the usual nursing care of children with autism spectrum disorder in special education schools. TRIAL REGISTRATION: Chinese Clinical Trials Registry, ChiCTR2100047699.

RESUMO

AIM: The aim of this work is to examine the effectiveness of a psychoeducational intervention on self-efficacy (primary outcome), anxiety, depression, treatment adherence, and health-related quality of life (HRQoL) of patients undergoing haemodialysis. METHODS: A two-group randomized controlled trial of 124 patients (65 and 59 patients in the intervention and control groups, respectively) recruited from a tertiary hospital in Singapore was conducted. Data were collected from January 2015 to June 2016. Outcomes were measured at baseline and 1, 3, and 6 months after the intervention. General linear model was used to analyse data. RESULTS: Our findings showed significant group effect on HRQoL (effects of kidney disease on daily life; p = 0.041), time effect on all outcomes (p < 0.05; except for treatment adherence behaviours and HRQoL [burden of kidney disease]), and group * time interaction effect on anxiety (p = 0.040) and depression (p = 0.003), with the intervention group reporting better outcomes. CONCLUSIONS: The positive effects of our intervention on patients' self-efficacy, psychological well-being, treatment adherence attitudes, and HRQoL implied its potential use in dialysis/renal centres to improve patients' self-care and health outcomes.

RESUMO

Disulfiram (DSF), a medication for alcoholism, has recently been used as a repurposing drug owing to its anticancer effects. Despite the crucial role of dendritic cells (DCs) in immune homeostasis and cancer therapy, the effects of DSF on the survival and function of DCs have not yet been studied. Therefore, we treated bone marrow-derived DCs with DSF and lipopolysaccharide (LPS) and performed various analyses. DCs are resistant to DSF and less cytotoxic than bone marrow cells and spleen cells. The viability and metabolic activity of DCs hardly decreased after treatment with DSF in the absence or presence of LPS. DSF did not alter the expression of surface markers (MHC II, CD86, CD40, and CD54), antigen uptake capability, or the antigen-presenting ability of LPS-treated DCs. DSF decreased the production of interleukin (IL)-12/23 (p40), but not IL-6 or tumor necrosis factor-α, in LPS-treated DCs. We considered the granulocyte-macrophage colony-stimulating factor (GM-CSF) as a factor to make DCs resistant to DSF-induced cytotoxicity. The resistance of DCs to DSF decreased when GM-CSF was not given or its signaling was inhibited. Also, GM-CSF upregulated the expression of a transcription factor XBP-1 which is essential for DCs' survival. This study demonstrated for the first time that DSF did not alter the function of DCs, had low cytotoxicity, and induced differential cytokine production.

RESUMO

Doxorubicin (DOX) and vincristine (VC) are anti-cancer drugs commonly used for lymphoma in veterinary and human medicine. However, there are several side effects caused by these drugs. In this study, the protective effects of sonicated Bordetella bronchiseptica bacterin (sBb) on dendritic cells (DCs) damaged by two anti-cancer drugs were investigated. DCs play important roles in the innate and adaptive immunity of hosts, especially activating T cells that can suppress tumor growth. The metabolic activity of DCs significantly increased after the treatment with sBb compared to that of control DCs. In addition, there was a marked change in mitochondrial integrity between DOX-treated DC and DOX + sBb-treated DCs. Flow cytometric analysis also demonstrated that sBb upregulated the expression of the surface markers of DCs, particularly CD54. In mixed lymphocyte responses, sBb significantly increased the antigen-presenting capability of DCs. In particular, sBb increased the capability of control DCs by approximately 150% and that of VC-treated DCs by 221%. These results suggest that sBb can be used as a potential immunostimulatory agent to protect DCs from anti-cancer drug-induced damage and provide fundamental information about using a combination of DCs and vincristine in immunotherapy.

RESUMO

Pregnancy gingivitis peaks during mid-pregnancy and resolves transiently towards the postpartum period. However, the role of maternal immune response in orchestrating gingival inflammation has not yet been fully understood. Hence, in this study, we examined the salivary protein profile during the three trimesters of pregnancy, in context to pregnancy gingivitis, employing iTRAQ-based quantitative proteomics. Unstimulated saliva was collected from 10 subjects in each trimester of pregnancy and postpartum period. Samples were analysed using iTRAQ analysis and ELISA and SEM was performed to validate results. Neutrophil mediated immune response was overrepresented in all three trimesters of pregnancy, despite the decrease in phagocytic responses during the second and third trimesters. ELISA showed a significantly higher Neutrophil Extracellular Traps (NETs) formation in the third trimester of pregnancy coinciding with the resolution of pregnancy gingivitis. The NETs-associated proteins (neutrophil elastase and myeloperoxidase) showed a positive correlation with estrogen hormones, which was also highest during the third trimester. Sex hormone-driven NETs formation could be the mainstay of defence that contributes to the remission of pregnancy gingivitis. This study has provided a new insight into the role of immune-modulation in pregnancy gingivitis, which will aid development of new therapeutics for managing pregnancy gingivitis in future.

RESUMO

PURPOSE: Colorectal cancer (CRC) surgeries are major, complex, and often associated with debilitating symptoms or significant deconditioning that may impair patients' quality of life. Little is known about how patients and family caregivers cope and their unmet needs during this daunting perioperative phase. This study aimed to explore the experiences and needs of CRC patients who undergo surgery and their family caregivers. METHODS: An exploratory qualitative design was adopted. A total of 27 participants comprising fifteen outpatients who had undergone colorectal cancer surgery and twelve family caregivers were recruited through purposive sampling from a public tertiary hospital in Singapore between December 2019 and November 2020. Individual, audio-recorded, semi-structured interviews were conducted, transcribed verbatim, and analyzed using thematic analysis. RESULTS: Four themes emerged: initial reactions to the diagnosis, impact of the illness and surgery, personal coping, and external support. The lack of apparent assessments on the psychological well-being of patients was found despite several participants exhibiting early signs of distress. Access to psychological support provided by healthcare professionals or peers was selective, and knowledge deficit was prevalent, especially in the preoperative stage. CONCLUSION: Psychological priming and strengthening are important for CRC patients' and their caregivers' adaptive coping throughout the treatment continuum. Technology-based, dyadic psychoeducation should be offered preoperatively to ease CRC patients' acceptance of their diagnosis and adjustment to life after surgery while at the same time reduce the burden of family carers.

RESUMO

AIMS: To synthesize the effectiveness of web-based psychosocial interventions on self-efficacy, anxiety, depression, quality of life (QoL), non-specific psychological and cancer-specific distress among patients with colorectal cancer (CRC). DESIGN: A systematic review and meta-analysis. DATA SOURCES: Six databases (PubMed, PsycINFO, Embase, Scopus, CINAHL and CNKI) were searched from inception to December 2021. REVIEW METHODS: Experimental/quasi-experimental studies involving patients with CRC for the improvement of aforementioned outcomes were included. Two reviewers screened and extracted the data, and assessed studies' methodological quality using risk of bias tools. Meta-analyses and narrative syntheses were performed. RESULTS: Nineteen studies consisting of 1386 participants were identified. Cognitive-behavioural therapy delivered online was the most common trialled web-based psychosocial intervention. Meta-analyses revealed no positive effect for self-efficacy (standardized mean difference 0.93, 95% CI: 0.52 to 1.35, p < .01) and minimal benefit for QoL (mean difference [MD] 2.83, 95% CI: -0.31 to 5.98, p = .08) but significant positive effects for anxiety (MD -2.23, 95% CI: -3.31 to -1.14, p < .01) and depression (MD -2.84, 95% CI: -4.09 to -1.59, p < .01) among CRC survivors in the intervention group as compared with the control group. Narrative synthesis suggested possible benefits in reducing distress. CONCLUSION: Web-based psychosocial interventions are promising alternatives to conventional delivery methods in reducing patients' anxiety, depression and distress. However, evidence on self-efficacy and QoL remains inconsistent. More adequately powered, well-designed trials with targeted and theory-based interventions are required to ascertain findings. IMPACT: By highlighting the potential of web-based psychosocial interventions in reducing anxiety and depression among CRC survivors, this review has put forth beneficial information supporting the use and acceptance of web-based care delivery in light of COVID-19 restrictions and nationwide lockdowns. Meanwhile, the paucity of empirical support reflects the necessity of more extensive research to test and improve other health outcomes. PROSPERO registration number: CRD42021261396.

RESUMO

Heat stress (HS) damages the global beef industry by reducing growth performance causing high economic losses each year. However, understanding the physiological mechanisms of HS in Hanwoo calves remains elusive. The objective of this study was to identify the potential biomarkers and metabolic pathways involving different levels of heat stress in Hanwoo calves. Data were collected from sixteen Hanwoo bull calves (169.6 ± 4.6 days old, BW of 136.9 ± 6.2 kg), which were maintained at four designated ranges of HS according to the temperature−humidity index (THI) including: threshold (22 to 24 °C, 60%; THI = 70 to 73), mild (26 to 28 °C, 60%; THI = 74 to 76), moderate (29 to 31 °C, 80%; THI = 81 to 83), and severe (32 to 34 °C, 80%; THI = 89 to 91) using climate-controlled chambers. Blood was collected once every three days to analyze metabolomics. Metabolic changes in the serum of calves were measured using GC-TOF-MS, and the obtained data were calculated by multivariate statistical analysis. Five metabolic parameters were upregulated and seven metabolic parameters were downregulated in the high THI level compared with the threshold (p < 0.05). Among the parameters, carbohydrates (ribose, myo-inositol, galactose, and lactose), organic compounds (acetic acid, urea, and butenedioic acid), fatty acid (oleic acid), and amino acids (asparagine and lysine) were remarkably influenced by HS. These novel findings support further in-depth research to elucidate the blood-based changes in metabolic pathways in heat-stressed Hanwoo beef calves at different levels of THI. In conclusion, these results indicate that metabolic parameters may act as biomarkers to explain the HS effects in Hanwoo calves.

RESUMO

AIMS: To explore nurses' perceptions of the transformation in Singapore's nursing education and its impact on the delivery of nursing care. BACKGROUND: Nursing education in Singapore has sailed through a sea of changes, from the apprenticeship model of training in hospitals to institutions of higher learning. Limited primary studies have explored the evolution of nursing education, and none have explored its impact on the delivery of nursing care, based on nurses' perceptions. METHODS: A descriptive qualitative design with purposive and snowball sampling was used to recruit 18 experienced nurses from local teaching institutions and healthcare clusters. Semistructured individual face-to-face interviews were conducted using an interview guide. Data were analysed using thematic analysis. The Consolidated Criteria for Reporting Qualitative Research reporting guideline was used to report the study. FINDINGS: Five themes emerged: 'evolution of the nursing education approach', 'clinical learning environments', 'evaluation of changes in the nursing education approach', 'attitudes toward the provision of various levels of education' and 'influences of various competencies on the delivery of nursing care'. CONCLUSION: Changes in teaching pedagogies, learning, assessment, curriculum structure, content and clinical learning environment were commonly reported, which provided insights into understanding nursing education transformation and its impact on nursing practice. IMPLICATIONS FOR NURSING EDUCATION: The findings could better prepare nurses for the demanding needs of the contemporary healthcare landscape. Nurse educators and leaders should evaluate gaps in nursing education and implement strategies to improve students' learning experiences and outcomes. IMPLICATIONS FOR NURSING POLICY: Policy-makers can draw on our findings to revise the core competencies guidelines and improve future training by supporting the healthcare needs of society.

RESUMO

Background and Objectives: The COVID-19 pandemic has caused global public panic, leading to severe mental illnesses, such as post-traumatic stress disorder (PTSD). This study aimed to establish a risk prediction model of PTSD based on a machine learning algorithm to provide a basis for the extensive assessment and prediction of the PTSD risk status in adults during a pandemic. Materials and Methods: Model indexes were screened based on the cognitive-phenomenological-transactional (CPT) theoretical model. During the study period (1 March to 15 March 2020), 2067 Chinese residents were recruited using Research Electronic Data Capture (REDCap). Socio-demographic characteristics, PTSD, depression, anxiety, social support, general self-efficacy, coping style, and other indicators were collected in order to establish a neural network model to predict and evaluate the risk of PTSD. Results: The research findings showed that 368 of the 2067 participants (17.8%) developed PTSD. The model correctly predicted 90.0% (262) of the outcomes. Receiver operating characteristic (ROC) curves and their associated area under the ROC curve (AUC) values suggested that the prediction model possessed an accurate discrimination ability. In addition, depression, anxiety, age, coping style, whether the participants had seen a doctor during the COVID-19 quarantine period, and self-efficacy were important indexes. Conclusions: The high prediction accuracy of the model, constructed based on a machine learning algorithm, indicates its applicability in screening the public mental health status during the COVID-19 pandemic quickly and effectively. This model could also predict and identify high-risk groups early to prevent the worsening of PTSD symptoms.
