Cross-cultural adaptation of the empowerment scale of pregnant women in China context: An integrative method of translation and linguistic validation.

AIM: To translate the Empowerment Scale for Pregnant Women (ESPW) into Chinese and to assess its linguistic validity. METHODS: The integrative method of the translation process, the Delphi technique, and cognitive interviews were used to implement cross-cultural adaptation and enhance comprehensibility and linguistic validation. This study recruited 14 experts in the expert review and cognitively reviewed 15 pregnant women. RESULTS: The two-round Delphi method created agreement on cultural applicability. The results of content validity achieved good levels: The item-level content validity index (CVI) ranged from 0.78 to 1.00, and the scale-level content validity index, calculated using two different formulas, were 0.97 and 0.81, respectively. Kappa values ranged from 0.74 to 1.00. Pregnant women could understand most of the items and response options in the cognitive interview. The revisions to the wording were made based on suggestions from experts and pregnant women. CONCLUSION: The prefinal simplified Chinese ESPW was semantically and conceptually equivalent to the English version, which was well prepared for further psychometric tests in the next stage of cross-cultural adaptation. PATIENT OR PUBLIC CONTRIBUTION: This comprehensive method successfully developed a Chinese tool to measure the empowerment of pregnant women, indicating the international applicability of this tool and the methodological scientific nature. The simplified Chinese ESPW has the potential to support the identification of empowerment levels of pregnant women and the evaluation of the effectiveness of health education and promotion programmes.

Psychometric validation of the Chinese version of the empowerment scale for pregnant women.

Empowering pregnant women is a crucial process that healthcare providers should evaluate, as empowerment is a meaningful indicator that can reflect the impact of health promotion and education in antenatal care. The Empowerment Scale for Pregnant Women (ESPW) is a reliable and valid instrument for measuring empowerment. The cross-sectional study was conducted to translate and validate the psychometric properties of the ESPW among 526 pregnant women in China. The forward-backward method was used to translate the English version of the ESPW into the Chinese version. Reliability was examined with the internal consistency and test-retest coefficients. Validity was analyzed with structural, dimensionality, convergent, discriminant, and concurrent validity. The Cronbach's α value of 0.97 and the intraclass correlation coefficient of 0.98 (95% confidence interval [CI], [0.96, 0.99]) demonstrated excellent internal consistency and test-retest reliability. Exploratory factor analysis revealed that five factors with eigenvalues > 1 explained 68.41% of the total variance. Confirmatory factor analysis verified an acceptable model that fit the data exceptionally. The Chinese-translated version of the ESPW (CV-ESPW) had acceptable convergent and discriminant validity. Concurrent validity was supported by the correlation between the total scores of the CV-ESPW and the Chinese version of the Patient Perceptions of the Empowerment Scale (r = 0.64, p < 0.001). The CV-ESPW is a valid and reliable assessment tool for measuring pregnant women's empowerment in China and can potentially contribute to evaluating the effectiveness of programs that empower pregnant women.

Development of a marital self-disclosure programme for alleviating the fear of cancer recurrence in patients with gastric cancer and undergoing chemotherapy: a modified Delphi method.

Aim: This study aimed to develop a marital self-disclosure programme to alleviate the fear of cancer recurrence in patients with gastric cancer who are undergoing chemotherapy. Design: Delphi method. Methods: Data from available literature and stakeholder interviews were utilised to formulate the initial draft of a marital self-disclosure programme aimed to alleviate the fear of cancer recurring in patients with gastric cancer and undergoing chemotherapy. A panel of experts subsequently conducted a two-round modified Delphi method to finalise the programme. Results: A total of 13 experts participated in the first round of consultation, while 11 experts were involved in the second round, as two experts withdrew due to unavailability. The response rates of both rounds of expert consultation were 100 and 84.62%, respectively, and the expert authority coefficients (Cr) of the programme were 0.83 and 0.84, respectively. The coordination coefficients of the expert opinions were 0.124 (χ2 = 61.214, p = 0.010) and 0.167 (χ2 = 69.668, p = 0.001) for each Delphi round. The average score of the second round was (4.545 ± 0.688) to (5.000 ± 0), with a full score ratio of 0.55-1.00. The coefficient of variation (CV) ranged from 0 to 0.031. Outcomes from both rounds of consultations were considered acceptable and credible. The finalised marital self-disclosure programme for alleviating the fear of cancer recurrence in patients with gastric cancer undergoing chemotherapy consists of two parts; disclosure guidance for patients and their spouse with nine items, and the structure and themes of marital self-disclosure with 31 items. Patient or public contribution: After two rounds of expert consultations, the marital self-disclosure programme for patients with gastric cancer undergoing chemotherapy is suggested to be scientifically valid and reliable. This programme is anticipated to potentially support patients and their spouses effectively by providing a reliable intervention plan focused on alleviating the fear of cancer recurrence.

Psychometric properties evaluation of the Advance Care Planning Readiness Scale for community-dwelling older adults with chronic diseases residing in suburban counties within the Chinese context.

AIM: To evaluate the psychometric properties of the Advance Care Planning Readiness Scale (ACPRS-C) within the context of community-dwelling older adults with chronic diseases residing in suburban counties in China. DESIGN: Descriptive, cross-sectional survey. METHODS: The research method employed in this study is characterized as a methodological study. Self-reported survey data were collected among community-dwelling older adults with chronic diseases residing in suburban counties in China. Including the following psychometric characteristics, item analysis was performed using the decision value method and Pearson's correlation analysis. Content validity was assessed through expert panel evaluation. The internal consistency of the questionnaire was determined by calculating Cronbach's alpha coefficient and corrected item-total correlation. Additionally, confirmatory factor analysis (CFA) was utilized to assess the construct validity of the ACPRS-C. RESULTS: A total of 228 older adults participated in this psychometric study from August to October 2023. The item content validity index ranged from 0.80 to 1.00, while the scale content validity index was 0.945. The scale demonstrated excellent internal consistency (Cronbach's alpha = 0.931), and the correlation between items and total score was satisfactory. The structural validity was deemed robust (CFA model fit: chi-square/df = 1.121, comparative fit index = 0.992). CONCLUSION: The ACPRS-C is a scale with strong psychometric properties to assess the ACP readiness within the context of community-dwelling older adults with chronic diseases residing in suburban counties in China. Its reliability and validity hold considerable significance for both research and clinical practice.

Marital Self-Disclosure Intervention for the Fear of Cancer Recurrence in Chinese Patients With Gastric Cancer: Protocol for a Quasiexperimental Study.

BACKGROUND: Patients with gastric cancer experience different degrees of fear of cancer recurrence. The fear of cancer recurrence can cause and worsen many physical and psychological problems. We considered the "intimacy and relationship processes in couples' psychosocial adaptation" model. OBJECTIVE: The study aims to examine the effectiveness of a marital self-disclosure intervention for improving the level of fear of cancer recurrence and the dyadic coping ability among gastric cancer survivors and their spouses. METHODS: This is a quasiexperimental study with a nonequivalent (pretest-posttest) control group design. The study will be conducted at 2 tertiary hospitals in Taizhou City, Jiangsu Province, China. A total of 42 patients with gastric cancer undergoing chemotherapy and their spouses will be recruited from each hospital. Participants from Jingjiang People's Hospital will be assigned to an experimental group, while participants from Taizhou People's Hospital will be assigned to a control group. The participants in the experimental group will be involved in 4 phases of the marital self-disclosure (different topics, face-to-face) intervention. Patients will be evaluated at baseline after a diagnosis of gastric cancer and reassessed 2 to 4 months after baseline. The primary outcome is the score of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF) for patients. The secondary outcomes are the scores of the FoP-Q-SF for partners and the Dyadic Coping Inventory. RESULTS: Research activities began in October 2022. Participant enrollment and data collection began in February 2023 and are expected to be completed in 12 months. The primary results of this study are anticipated to be announced in June 2024. CONCLUSIONS: This study aims to assess a marital self-disclosure intervention for improving the fear of cancer recurrence in Chinese patients with gastric cancer and their spouses. The study is likely to yield desirable positive outcomes as marital self-disclosure is formulated based on evidence and inputs obtained through stakeholder interviews and expert consultation. The study process will be carried out by nurses who have received psychological training, and the quality of the intervention will be strictly controlled.

Measuring empowerment in pregnant women: A scoping review of progress in instruments.

BACKGROUND: The empowerment of pregnant women is a meaningful strategy that profoundly impacts the health of women and their children. Despite a significant increase in the empowerment of pregnant women and its measurement, little attention was given to a consensus on the selection and application of assessment instruments used for pregnant women. OBJECTIVE: To identify the available assessment instruments for measuring the empowerment of pregnant women and to describe the appraisal content and their psychometric properties. METHODS: We searched nine bibliographic databases for original studies that focus on the measurement of empowerment in pregnant women. Arksey and O'Malley's methodology and PRISMA-ScR were selected to guide the implementation of this scoping review. The COSMIN criteria was employed to assess the methodological quality and the quality of psychometric properties. RESULTS: A total of 23 studies were included and 13 instruments were extracted. Given comprehensive considerations, Kameda's prenatal empowerment scale may be deemed suitable. The included instruments comprehensively measured the attributes of empowerment, with a particular focus on facilitating women's choice and decision-making. Except for the four most recent self-designed questionnaires, the remaining instruments had been tested for reliability and/or validity. CONCLUSION: There were heterogeneous results regarding the included instruments' appraisal content and psychometric properties. Future studies focusing on the development or validation of measurement instruments should be guided by influential and identical standards.

Nurses' Burnout, Resilience, and Its Associated Factors in Sichuan, China, During the Peak of Coronavirus Disease 2019 Infection.

AIM: To investigate the level of burnout and resilience, and the associated factors when the coronavirus disease 2019 infection hit a peak in the community in Sichuan, China. METHOD: This was a descriptive cross-sectional design study. Data were collected from 25 to 31 December 2022, at six hospitals in Sichuan province. Using convenience sampling, a total of 717 participants were recruited, using the revised version of the Maslach Burnout InventoryGeneral Survey, and the Resilience Assessment Scale for healthcare workers. RESULTS: More than half of nurses reported a moderate level of emotional exhaustion (66.50%, n = 484), cynicism (68.20%, n = 489), and personal accomplishment (68.76%, n = 493); nearly one-third and one-fourth of nurses experienced a high level of emotional exhaustion (27.48%, n = 197) and cynicism (20.78%, n = 149), respectively. In resilience, the highest scoring dimension was interpersonal connectedness, followed by decisional coping, flexible self-adaptation, and rational thinking. Satisfaction with work income, patient-nurse conflict, frequency of overtime work, age, and marital status were significant factors influencing burnout among nurses (p < .05). CONCLUSION: The findings of the study enlighten nursing administrators on the level of burnout and resilience and associated factors among nurses during the peak of coronavirus disease 2019 infection in China. This would be of immense help in planning a welfare program to support the nurses.

The mediating role of coping styles in the relationship between second victim experience and professional quality of life among nurses: a cross-sectional study.

BACKGROUND: Studies have shown that second-victim experiences could increase risks of the compassion fatigue while support from individuals and organisations is most often protection. However, the risk for poor compassion satisfaction and increased compassion fatigue in nurses aroused by adverse events remains an underestimated problem, meanwhile, litter known about the role of positive and negative coping styles among nurses suffering from adverse events. This study aims to investigate the effect of second-victim experiences on the professional quality of life among nurses and to determine the mediating role of coping styles in the relationship between second-victim experiences and professional quality of life. METHODS: Multistage sampling was used to recruit registered nurses from Hunan province in China. Registered nurses who identified themselves as experiencing adverse events from nine tertiary hospitals were included in this study. Participants were recruited to complete a survey on the second victim experience and support tool, the simplified coping style questionnaire, and the professional quality of life scale. The stress coping theory was used to develop the framework in this study. The structural equation modelling approach was used for conducting the mediating effects analysis via IBM SPSS Statistics 26.0 and Mplus 8.3. RESULTS: In total, 67% (n = 899) of nurses reported a second victim experience during their careers. In a bivariate analysis, both second-victims experiences and coping styles were significantly associated with their professional quality of life. The results showed that the effects of second victim experiences on their professional quality of life were fully mediated by coping styles. A total of 10 significantly indirect pathways were estimated, ranging from -0.243 to 0.173. CONCLUSIONS: Second-victim experiences are common among nurses in this study. Since the mediating effects of coping styles were clarified in this study, it is imperative to promote the perception of negative coping styles and encourage nurses to adopt more positive coping styles with adequate support systems.

The mediating role of psychological capital in the relationship between job stress and professional identity in Chinese medical interns.

BACKGROUND: Adaption to clinical work during the internship can induce several stressors among medical students, especially in the context of the coronavirus disease 2019 (COVID-19) pandemic. Particularly, job stress could be linked to the development of psychological traits and the formation of the professional identity of medical interns. OBJECTIVE: This study aimed to explore the relationship between job stress, psychological capital, and professional identity through a mediation analysis of Chinese medical interns. METHODS: A descriptive cross-sectional study was conducted in 30 hospitals and clinics in China from June 2021 to March 2022. A total of 665 medical interns filled out questionnaires related to demographic questions, psychological capital, job stress, and professional identity. Data analysis was executed using the IBM SPSS version 22.0 software and its add-in PROCESS Windows version 4.0. RESULTS: The findings indicated a statistically significant mediating effect of psychological capital between job stress and professional identity. Job stress and job stress combined with psychological capital accounted for 5.3% and 37.9%, respectively, of the variance in professional identity. The bootstrapping method corroborated the significance of the indirect effect of job stress through psychological capital (95% bootstrap CI = -4.7921, -2.4345). CONCLUSION: The current findings underscore the need for increased attention on improving the psychological capital of medical interns.

Effects of marital self-disclosure on marital relationship and psychological outcome for cancer patients: a systematic review.

PURPOSE: Literature on marital self-disclosure interventions for cancer patients lacks consistency in methodology and content. Moreover, the impact of such interventions on physical and psychological health, marital relationships, and self-disclosure ability is controversial. This review aims to systematically analyze the studies of marital self-disclosure intervention, synthesize the structure and topics of marital self-disclosure, and summarize and evaluate its effects on improving physical and psychological outcomes and marital relationships in cancer patients and their spouses. METHOD: This systematic review used the preferred reporting items of Systematic Reviews and Meta-Analyses (PRISMA). We conducted a systematic review of randomized controlled and quasi-experimental studies published from the establishment of the database to October 2022. Marital self-disclosure interventions were conducted with both cancer patients and their spouses. Studies published in a language other than English or Chinese, and studies below a quality grade of C were excluded. Data were extracted through a standardized data collection form, and two reviewers independently extracted and evaluated the data. The quality of the included studies was assessed using the Cochrane Handbook of Systematic Reviews of Interventions, and a third reviewer adjudicated in case of disagreement. The data were synthesized by vote counting based on direction of effect according to the Synthesis Without Meta-analysis (SWiM) reporting guideline. RESULTS: Thirteen studies were included in the review. Based on quality evaluation, three studies were categorized as grade A (good), and ten studies were grade B (moderate). Seven studies reported moderate rates of participant refusal and attrition. The structure and topics of marital self-disclosure varied across different studies. The five studies had various prespecified disclosure topics, such as fear of cancer recurrence, benefit finding, and emotional distress. The overall results suggest that marital self-disclosure interventions can improve physical and psychological health, enhance marital relationships, and increase self-disclosure ability. CONCLUSION: The limited number of studies, small sample sizes, diverse intervention strategies, and methodological heterogeneity weakened the evidence base for the effectiveness of marital self-disclosure interventions. Therefore, further high-quality randomized controlled trials (RCTs) are recommended to confirm the effectiveness of such interventions. These studies should also evaluate the interventions' long-term impact, analyze optional topics and methods, identify key features, and explore the development of the best intervention program.

Nurses' Perception and Satisfaction Toward Electronic Medical Record System.

AIM: This study aims to assess the perception and satisfaction of nurses toward the electronic medical record system in a teaching hospital. METHOD: A cross-sectional study was conducted among 350 nurses in a teaching hospital via a self-administered questionnaire between May to October 2019. Descriptive analysis, independent t-test, analysis of variance, and hierarchical multiple regression were used to analyze the data using Statistical Package for Social Sciences software version 25. In addition, a The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) was used as guide in reporting the results of this study. RESULTS: Almost all the nurses (98%, n = 343) had a positive perception toward the electronic medical record system, though their perceptions significantly differ across work units, computer or laptop ownership, and daily time spent on the system (all p < .05). Nurses who had received training reported better satisfaction with the system. CONCLUSION: Among the issues highlighted by the participants that warrant attention were system development and connectivity. This study, therefore, emphasizes the involvement of nursing personnel in system development to ensure an appropriate approach for nursing care delivery.

Intraneuronal sortilin aggregation relative to granulovacuolar degeneration, tau pathogenesis and sorfra plaque formation in human hippocampal formation.

Extracellular ß-amyloid (Aß) deposition and intraneuronal phosphorylated-tau (pTau) accumulation are the hallmark lesions of Alzheimer's disease (AD). Recently, "sorfra" plaques, named for the extracellular deposition of sortilin c-terminal fragments, are reported as a new AD-related proteopathy, which develop in the human cerebrum resembling the spatiotemporal trajectory of tauopathy. Here, we identified intraneuronal sortilin aggregation as a change related to the development of granulovacuolar degeneration (GVD), tauopathy, and sorfra plaques in the human hippocampal formation. Intraneuronal sortilin aggregation occurred as cytoplasmic inclusions among the pyramidal neurons, co-labeled by antibodies to the extracellular domain and intracellular C-terminal of sortilin. They existed infrequently in the brains of adults, while their density as quantified in the subiculum/CA1 areas increased in the brains from elderly lacking Aß/pTau, with pTau (i.e., primary age-related tauopathy, PART cases), and with Aß/pTau (probably/definitive AD, pAD/AD cases) pathologies. In PART and pAD/AD cases, the intraneuronal sortilin aggregates colocalized partially with various GVD markers including casein kinase 1 delta (Ck1δ) and charged multivesicular body protein 2B (CHMP2B). Single-cell densitometry established an inverse correlation between sortilin immunoreactivity and that of Ck1δ, CHMP2B, p62, and pTau among pyramidal neurons. In pAD/AD cases, the sortilin aggregates were reduced in density as moving from the subiculum to CA subregions, wherein sorfra plaques became fewer and absent. Taken together, we consider intraneuronal sortilin aggregation an aging/stress-related change implicating protein sorting deficit, which can activate protein clearance responses including via enhanced phosphorylation and hydrolysis, thereby promoting GVD, sorfra, and Tau pathogenesis, and ultimately, neuronal destruction and death.

The COVID-19 Global Pandemic and Its Impact on the Mental Health of Nurses in Malaysia.

The Coronavirus disease 2019 (COVID-19) global pandemic since its onset has had a dramatic and often devastating impact, both physical and psychological, on all healthcare workers. This study aimed to assess the impact of psychological distress that COVID-19 has on nurses, as well as the coping strategies that they employed. This is a cross-sectional national online survey. A total of 859 nurses actively involved in caring for patients with suspected or confirmed COVID-19 in Malaysia participated in the study. More than three-quarters of the nurses experienced stress (77.2%). A total of 88.7% and 7.2% of nurses revealed a moderate and high stress level, respectively. Approximately one in eight (12.1%) nurses reported feeling depressed. Nurses working in the outpatient departments reported significantly higher stress levels than nurses working in inpatient care departments. Nurses having chronic health problems reported significantly higher depression levels than nurses with no chronic health problem. Highly stressed or depressed nurses tend to adopt avoidance coping strategies while religion and emotional support were used regardless of the stress or depression levels experienced. The findings of the study provide insight into the mental health and coping strategies of nurses actively involved in caring for patients with suspected or confirmed COVID-19 in Malaysia. This would be of tremendous help to nursing administrators in implementing mental health services for nurses during and following the COVID-19 global pandemic.

Escalating progression of mental health disorders during the COVID-19 pandemic: Evidence from a nationwide survey.

Since the first nationwide movement control order was implemented on 18 March 2020 in Malaysia to contain the coronavirus disease 2019 (COVID-19) outbreak, to what extent the uncertainty and continuous containment measures have imposed psychological burdens on the population is unknown. This study aimed to measure the level of mental health of the Malaysian public approximately 2 months after the pandemic's onset. Between 12 May and 5 September 2020, an anonymous online survey was conducted. The target group included all members of the Malaysian population aged 18 years and above. The Depression Anxiety Stress Scale (DASS-21) was used to assess mental health. There were increased depressive, anxiety and stress symptoms throughout the study period, with the depression rates showing the greatest increase. During the end of the data collection period (4 August-5 September 2020), there were high percentages of reported depressive (59.2%) and anxiety (55.1%) symptoms compared with stress (30.6%) symptoms. Perceived health status was the strongest significant predictor for depressive and anxiety symptoms. Individuals with a poorer health perception had higher odds of developing depression (odds ratio [OR] = 5.68; 95% confidence interval [CI] 3.81-8.47) and anxiety (OR = 3.50; 95%CI 2.37-5.17) compared with those with a higher health perception. By demographics, young people-particularly students, females and people with poor financial conditions-were more vulnerable to mental health symptoms. These findings provide an urgent call for increased attention to detect and provide intervention strategies to combat the increasing rate of mental health problems in the ongoing COVID-19 pandemic.

Informal carer's knowledge of traumatic brain injury questionnaire: Initial development and validation.

AIM: To develop and psychometrically test the instrument for measuring the knowledge of traumatic brain injury of informal carers. DESIGN: Instrument development. METHOD: Focus group discussions were conducted among informal carers and healthcare specialists in March 2017. The content validity was determined by the mean of the item content validity index. A reliability test was performed by the Kuder-Richardson 20 and Pearson's correlation coefficient among 40 informal carers of patients with a traumatic brain injury in the rehabilitation medicine department of a tertiary hospital from August-September 2017. RESULTS: The final 34-item questionnaire covers the nature of traumatic brain injury, the consequences of traumatic brain injury, the rehabilitation process, and the role of the caregiver. The item content means ranged from 0.8-1.00, and the difficulty of knowledge items ranged from 0.18-0.98. The internal consistency reliability and correlation coefficient were 0.70 and 0.84, respectively.

Evaluating Safety and Efficacy of Follow-up for Patients With Abdominal Pain Using Video Consultation (SAVED Study): Randomized Controlled Trial.

BACKGROUND: The benefits of telemedicine include cost savings and decentralized care. Video consultation is one form that enables early detection of deteriorating patients and promotion of self-efficacy in patients who are well but anxious. Abdominal pain is a common symptom presented by patients in emergency departments. These patients could benefit from video consultation, as it enables remote follow-up of patients who do not require admission and facilitates early discharge of patients from overcrowded hospitals. OBJECTIVE: The study aimed to evaluate the safety and efficacy of the use of digital telereview in patients presenting with undifferentiated acute abdominal pain. METHODS: The SAVED study was a prospective randomized controlled trial in which follow-up using existing telephone-based telereview (control) was compared with digital telereview (intervention). Patients with undifferentiated acute abdominal pain discharged from the emergency department observation ward were studied based on intention-to-treat. The control arm received routine, provider-scheduled telereview with missed reviews actively coordinated and rescheduled by emergency department staff. The intervention arm received access to a platform for digital telereview (asynchronous and synchronous format) that enabled patient-led appointment rescheduling. Patients were followed-up for 2 weeks for outcomes of service utilization, efficacy (compliance with their disposition plan), and safety (re-presentation for the same condition). RESULTS: A total of 70 patients participated, with patients randomly assigned to each arm (1:1 ratio). Patients were a mean age of 40.0 (SD 13.8; range 22-71) years, predominantly female (47/70, 67%), and predominantly of Chinese ethnicity (39/70, 56%). The telereview service was used by 32 patients in the control arm (32/35, 91%) and 18 patients in the intervention arm (18/35, 51%). Most patients in control (33/35, 94%; 95% CI 79.5%-99.0%) and intervention (34/35, 97%; 95% CI 83.4%-99.9%) arms were compliant with their final disposition. There was a low rate of re-presentation at 72 hours and 2 weeks for both control (72 hours: 2/35, 6%; 95% CI 1.0%-20.5%; 2 weeks: 2/35, 6%, 95% CI 1.0%-20.5%) and intervention (72 hours: 2/35, 6%; 95% CI 1.0%-20.5%; 2 weeks: 3/35, 9%, 95% CI 2.2%-24.2%) arms. There were no significant differences in safety (P>.99) and efficacy (P>.99) between the two groups. CONCLUSIONS: The application of digital telereview for the follow-up of patients with abdominal pain may be safe and effective. Future studies are needed to evaluate its cost-effectiveness and usefulness for broader clinical application.

A SOC1-like gene MtSOC1a promotes flowering and primary stem elongation in Medicago.

Medicago flowering, like that of Arabidopsis, is promoted by vernalization and long days, but alternative mechanisms are predicted because Medicago lacks the key regulators CO and FLC. Three Medicago SOC1-like genes, including MtSOC1a, were previously implicated in flowering control, but no legume soc1 mutants with altered flowering were reported. Here, reverse transciption-quantitative PCR (RT-qPCR) indicated that the timing and magnitude of MtSOC1a expression was regulated by the flowering promoter FTa1, while in situ hybridization indicated that MtSOC1a expression increased in the shoot apical meristem during the floral transition. A Mtsoc1a mutant showed delayed flowering and short primary stems. Overexpression of MtSOC1a partially rescued the flowering of Mtsoc1a, but caused a dramatic increase in primary stem height, well before the transition to flowering. Internode cell length correlated with stem height, indicating that MtSOC1a promotes cell elongation in the primary stem. However, application of gibberellin (GA3) caused stem elongation in both the wild type and Mtsoc1a, indicating that the mutant was not defective in gibberellin responsiveness. These results indicate that MtSOC1a may function as a floral integrator gene and promotes primary stem elongation. Overall, this study suggests that apart from some conservation with the Arabidopsis flowering network, MtSOC1a has a novel role in regulating aspects of shoot architecture.

What influences student nurses' intention to work with older people? A cross-sectional study.

BACKGROUND: Studies have reported that student nurses hold positive attitudes towards older people; nevertheless, working with older people has consistently remained one of the least desired career choices among student nurses in most countries. OBJECTIVES: The current study aimed to assess student nurses' intentions to work with older people and to determine the predictors of working intentions among nursing students. DESIGN: The study adopted a cross-sectional design. SETTINGS: Multistage sampling was used to recruit nursing students from five states in Malaysia. PARTICIPANTS: A total of 1462 nursing students from eleven nursing education institutions participated in this study. METHODS: A self-administered questionnaire was used to collect data. This study is underpinned by the Theory of Planned Behaviour. The Intent to Work with Older People Scale and Kogan Attitudes Toward Old People Scale were used to assess nursing students' intentions and attitudes towards care of older people respectively. Researcher-developed instruments were used to assess subjective norms and perceived behavioural control among nursing students. RESULTS: The present study found that nursing students in Malaysia demonstrated a moderate level of intention to work with older people, with a mean of 39.72 (±4.38). There were significant differences in effects of gender, ethnic group, academic level, type of nursing institution and setting of older person care clinical experience on intentions to work with older people. There was a moderate and positive relationship between attitudes towards older people and intentions to work with older people, as well as between perceived behavioural control and intentions to work with older people; it was found that r = 0.36 for both relationships. Attitudes, subjective norms and perceived behavioural control accounted for 19.7% of the variance in intentions to work with older people. CONCLUSION: The primary findings of this national study revealed that Malaysian nursing students have a moderate level of intention to work with older people. It is imperative to develop educational interventions to nurture attitudes for caring and promote stronger intentions to work with older people.

A systematic review of psychometric testing of instruments that measure intention to work with older people.

AIMS: To review systematically the psychometric properties of instruments used to measure intention to work with older people. BACKGROUND: Nursing students are part of the future healthcare workforce; thus, being aware of their intention to work with older people would give valuable insights to nursing education and practice. Despite a plethora of research on measuring intention to work with older people, a valid and reliable instrument has not been identified. DESIGN: A systematic literature review of evidence and psychometric properties. DATA SOURCES: Eight database searches were conducted between 2006 - 2016. REVIEW METHODS: English articles were selected based on inclusion and exclusion criteria. The COSMIN checklist was used to assess instruments reporting a psychometric evaluation of validity and reliability. RESULTS: Of 41 studies identified for full text review, 36 met the inclusion criteria. Seven different types of instruments were identified for psychometric evaluation. Measures of reliability were reported in eight papers and validity in five papers. Evidence for each measurement property was limited, with each instrument demonstrating a lack of information on measurement properties. Based on the COSMIN checklist, the overall quality of the psychometric properties was rated as poor to good. CONCLUSION: No single instrument was found to be optimal for use. Studies of high methodological quality are needed to properly assess the measurement properties of the instruments that are currently available. Until such studies are available, we recommend using existing instruments with caution.

MtVRN2 is a Polycomb VRN2-like gene which represses the transition to flowering in the model legume Medicago truncatula.

Optimising the timing of flowering contributes to successful sexual reproduction and yield in agricultural plants. FLOWERING LOCUS T (FT) genes, first identified in Arabidopsis thaliana (Arabidopsis), promote flowering universally, but the upstream flowering regulatory pathways can differ markedly among plants. Flowering in the model legume, Medicago truncatula (Medicago) is accelerated by winter cold (vernalisation) followed by long day (LD) photoperiods leading to elevated expression of the floral activator, FT-like gene FTa1. However, Medicago, like some other plants, lacks the activator CONSTANS (CO) and the repressor FLOWERING LOCUS C (FLC) genes which directly regulate FT and are key to LD and vernalisation responses in Arabidopsis. Conversely, Medicago has a VERNALISATION2-LIKE VEFS-box gene (MtVRN2). In Arabidopsis AtVRN2 is a key member of a Polycomb complex involved in stable repression of Arabidopsis FLC after vernalisation. VRN2-like genes have been identified in other eudicot plants, but their function has never been reported. We show that Mtvrn2 mutants bypass the need for vernalisation for early flowering in LD conditions in Medicago. Investigation of the underlying mechanism by transcriptome analysis reveals that Mtvrn2 mutants precociously express FTa1 and other suites of genes including floral homeotic genes. Double-mutant analysis indicates that early flowering is dependent on functional FTa1. The broad significance of our study is that we have demonstrated a function for a VRN2-like VEFS gene beyond the Brassicaceae. In particular, MtVRN2 represses the transition to flowering in Medicago by regulating the onset of expression of the potent floral activator, FTa1.
