The TMEM132B-GABAA receptor complex controls alcohol actions in the brain.

Alcohol is the most consumed and abused psychoactive drug globally, but the molecular mechanisms driving alcohol action and its associated behaviors in the brain remain enigmatic. Here, we have discovered a transmembrane protein TMEM132B that is a GABAA receptor (GABAAR) auxiliary subunit. Functionally, TMEM132B promotes GABAAR expression at the cell surface, slows receptor deactivation, and enhances the allosteric effects of alcohol on the receptor. In TMEM132B knockout (KO) mice or TMEM132B I499A knockin (KI) mice in which the TMEM132B-GABAAR interaction is specifically abolished, GABAergic transmission is decreased and alcohol-induced potentiation of GABAAR-mediated currents is diminished in hippocampal neurons. Behaviorally, the anxiolytic and sedative/hypnotic effects of alcohol are markedly reduced, and compulsive, binge-like alcohol consumption is significantly increased. Taken together, these data reveal a GABAAR auxiliary subunit, identify the TMEM132B-GABAAR complex as a major alcohol target in the brain, and provide mechanistic insights into alcohol-related behaviors.

TikTok as a teaching and learning method for nursing students: A quasi-experimental study.

BACKGROUND: Social networks have emerged as powerful tools in education, offering new opportunities for interactive learning. TikTok has gained popularity among young people and has potential for use as a teaching tool in health disciplines. OBJECTIVE: To evaluate the effectiveness of an educational program based on a multimodal intervention using the TikTok platform to improve theoretical-practical knowledge about diabetic debut and vaccination schedules and satisfaction in nursing students. DESIGN: A quasi-experimental study design. SETTINGS: Faculty of Nursing, University of Cadiz, Spain. PARTICIPANTS: 74 third-year undergraduate university nursing students. METHODS: According to Kolb's experiential learning model, a multimodal educational intervention was carried out during the academic year 2022/2023, with 12 h of training. In these sessions, theoretical content on the vaccination calendar and diabetic debut was developed with written case studies. In the last session, 19 working groups were formed and each group was given a practical case study to solve through role-playing and creating a video in TikTok. A questionnaire to measure individual knowledge and a rubric questionnaire were used to evaluate the simulations in TikTok platform. RESULTS: A significant improvement (z = 6.843, p < 0.001) was observed in the mean scores (9.93 ± 1.65) of the posttest of the knowledge questionnaire, used to evaluate abstract conceptualisation abilities. Additionally, a mean score of 10.42 (SD = 1.42) of the items on the rubric questionnaire, designed to assess active experimentation and reflective observation abilities, were correctly performed. It stands out that 97.1 % of the students positively valued the elements of teaching innovation implemented, while 82.9 % showed a high level of satisfaction with their activity. CONCLUSION: A multimodal educational intervention using TikTok platform proved to be effective in improving the acquisition of theoretical-practical knowledge in the university students included in the study. Therefore, this type of experiential training is recommended for the training of future health professionals.

Quality of care assessment for non-small cell lung cancer patients: transforming routine care data into a continuous improvement system.

PURPOSE: The complexity of cancer care requires planning and analysis to achieve the highest level of quality. We aim to measure the quality of care provided to patients with non-small cell lung cancer (NSCLC) using the data contained in the hospital's information systems, in order to establish a system of continuous quality improvement. METHODS/PATIENTS: Retrospective observational cohort study conducted in a university hospital in Spain, consecutively including all patients with NSCLC treated between 2016 and 2020. A total of 34 quality indicators were selected based on a literature review and clinical practice guideline recommendations, covering care processes, timeliness, and outcomes. Applying data science methods, an analysis algorithm, based on clinical guideline recommendations, was set up to integrate activity and administrative data extracted from the Electronic Patient Record along with clinical data from a lung cancer registry. RESULTS: Through data generated in routine practice, it has been feasible to reconstruct the therapeutic trajectory and automatically calculate quality indicators using an algorithm based on clinical practice guidelines. Process indicators revealed high adherence to guideline recommendations, and outcome indicators showed favorable survival rates compared to previous data. CONCLUSIONS: Our study proposes a methodology to take advantage of the data contained in hospital information sources, allowing feedback and repeated measurement over time, developing a tool to understand quality metrics in accordance with evidence-based recommendations, ultimately seeking a system of continuous improvement of the quality of health care.

Age-, region-, and day/night-related variation of the chloride reversal potential in the rat suprachiasmatic nucleus.

The master control of mammalian circadian rhythms is the suprachiasmatic nucleus (SCN), which is formed by the ventral and dorsal regions. In SCN neurons, GABA has an important function and even excitatory actions in adulthood. However, the physiological role of this neurotransmitter in the developing SCN is unknown. Here, we recorded GABAergic postsynaptic currents (in the perforated-patch configuration using gramicidin) to determine the chloride reversal potential (ECl) and also assessed the immunological expression of the Na-K-Cl cotransporter 1 (NKCC1) at early ages of the rat (postnatal days (P) 3 to 25), during the day and night, in the two SCN regions. We detected that ECl greatly varied with age and depending on the SCN region and time of day. Broadly speaking, ECl was more hyperpolarized with age, except for the oldest age studied (P20-25) in both day and night in the ventral SCN, where it was less negative. Likewise, ECl was more hyperpolarized in the dorsal SCN both during the day and at night; while ECl was more negative at night both in the ventral and the dorsal SCN. Moreover, the total NKCC1 fluorescent expression was higher during the day than at night. These results imply that NKCC1 regulates the circadian and developmental fluctuations in the [Cl-]i to fine-tune ECl, which is crucial for either excitatory or inhibitory GABAergic actions to occur in the SCN.

Role of the health literacy assessment in healthcare: Content validation of "Health Literacy Behaviour" nursing outcome.

PURPOSE: To validate the content of the "Health Literacy Behaviour" nursing outcome (NO). METHODS: A content validation study was conducted during 2022. Each indicator was included in the NO, and its response levels were operationally defined. The initial version of each indicator and its response levels were refined and validated through the Delphi method. A panel of health literacy (HL) and nursing taxonomies experts evaluated the content through two content validity indicators. The content validity of the NO and each index was determined by calculating the content validity index (CVI). A qualitative analysis of the recommendations provided by the experts was carried out to improve the understanding of the indicators and their levels. FINDINGS: A total of 108 experts participated in this study. Mostly females with more than 10 years of professional experience. The results demonstrated a high CVI of the indicators and the NO "Health Literacy Behaviour." All indicators achieved excellent (CVI ≥ 0.80) relevance and clarity. The CVI universal average method (CVI-p) of the NO achieved an excellent result of 0.90. CONCLUSIONS: The indicators included in the NO "Health Literacy Behaviour" have content validity. IMPLICATIONS FOR NURSING PRACTICE: These findings provide evidence-based indicators to measure the patient's actions to obtain, process, and understand information about health and disease, interact with the health system, and make informed health decisions. The validation of this NO would identify populations with low HL, allowing the health of this community to be promoted. Health literacy should be a priority objective of health management and policies.

Clinical approach for managing patients with unexpected CDH1 mutations: A case report.

BACKGROUND: Hereditary diffuse gastric cancer (HDGC) (OMIM# 137215) is an autosomal dominant cancer syndrome associated with CDH1 (OMIM# 192090) mutations. Prophylactic total gastrectomy (PTG) is the most recommended preventive treatment when a pathogenic mutation is found. However, the increasing use of genetic testing has led to the identification of incidental CDH1 mutations in individuals without a family history of gastric cancer. It remains unclear whether these patients should undergo prophylactic total gastrectomy. METHODS: Germline DNA, obtained from peripheral blood, was analysed by NGS. RESULTS: A 47-year-old woman was diagnosed with high-grade serous ovarian carcinoma, FIGO stage IIIC, with a Homologous Recombination Deficiency (HRD) GIS status of 78 (positive, cut-off: 43). She received chemotherapy and niraparib treatment. A multigene panel test revealed no pathogenic mutations in BRCA1 (OMIM# 113705)/BRCA2 (OMIM# 600185) genes, but a de novo deletion of exon 16 in CDH1 was found incidentally. She had no previous family history of gastric or breast cancer. The patient was enrolled in a surveillance program involving periodic endoscopy and was diagnosed with diffuse gastric cancer through biopsies of a pale area in the antrum after 1 year of close endoscopic follow-up. CONCLUSION: This case presents supportive evidence for the pathogenic classification of the loss of the last exon of CDH1.

Workplace health promotion programs: The role of compliance with workers' expectations, the reputation and the productivity of the company.

INTRODUCTION: Addressing the health and safety of workers is key to achieving Sustainable Development Goals 3 and 8. The European Union urges companies in its member countries to promote measures in this regard. However, this type of program is not a general approach in European companies. This study aims to identify whether the implementation of Workplace Health Promotion measures is influenced by the company's desire to meet its employees' expectations in this area; and if this relationship involves the company's reputation and productivity. METHODS: A multi-step methodology is used (descriptive sample portrait, analysis of influences by linear regression, and double-intermediation model analysis) to find out if reputation and productivity mediate the relationship between the satisfaction of employee health expectations and the number of Workplace Health Promotion measures applied. RESULTS: The more weight the company gives to this compliance, the more motivated it is to implement a more significant number of Workplace Health Promotion measures. The increase in productivity does not seem to weigh in this relationship, but the improvement of the company's reputation does. CONCLUSIONS: The more the employees' expectations of working in a healthy company are desired to be met, the more measures the company will put in place. PRACTICAL APPLICATIONS: The findings have theoretical implications, by increasing knowledge about the factors that influence a company's decision to activate Workplace Health Promotion policies. They can also serve as guidance for implementing policies that encourage health promotion in companies and contribute to the achievement of Sustainable Development Goals 3 and 8: for workers' representatives, by better understanding how these factors influence the fulfillment of their constituents' expectations; for company managers, by better knowing the variables involved in this relationship; and for researchers of this topic.

Generation and External Validation of a Histologic Transformation Risk Model for Patients with Follicular Lymphoma.

Follicular lymphoma (FL) is the most frequent indolent lymphoma. Some patients (10%-15%) experience histologic transformation (HT) to a more aggressive lymphoma, usually diffuse large B-cell lymphoma (DLBCL). This study aimed to validate and improve a genetic risk model to predict HT at diagnosis.We collected mutational data from diagnosis biopsies of 64 FL patients. We combined them with the data from a previously published cohort (total n = 104; 62 from nontransformed and 42 from patients who did transform to DLBCL). This combined cohort was used to develop a nomogram to estimate the risk of HT. Prognostic mutated genes and clinical variables were assessed using Cox regression analysis to generate a risk model. The model was internally validated by bootstrapping and externally validated in an independent cohort. Its performance was evaluated using a concordance index and a calibration curve. The clinicogenetic nomogram included the mutational status of 3 genes (HIST1HE1, KMT2D, and TNFSR14) and high-risk Follicular Lymphoma International Prognostic Index and predicted HT with a concordance index of 0.746. Patients were classified as being at low or high risk of transformation. The probability HT function at 24 months was 0.90 in the low-risk group vs 0.51 in the high-risk group and, at 60 months, 0.71 vs 0.15, respectively. In the external validation cohort, the probability HT function in the low-risk group was 0.86 vs 0.54 in the high-risk group at 24 months, and 0.71 vs 0.32 at 60 months. The concordance index in the external cohort was 0.552. In conclusion, we propose a clinicogenetic risk model to predict FL HT to DLBLC, combining genetic alterations in HIST1H1E, KMT2D, and TNFRSF14 genes and clinical features (Follicular Lymphoma International Prognostic Index) at diagnosis. This model could improve the management of FL patients and allow treatment strategies that would prevent or delay transformation.

The infectivity of AAV9 is influenced by the specific location and extent of chemically modified capsid residues.

BACKGROUND: Several treatments for genetic diseases utilizing recombinant adeno-associated viruses (AAVs) have recently gained approval. However, the development of a greater number of therapeutic AAVs is constrained by certain limitations. While extensive efforts have concentrated on screening AAV genetic libraries, an alternative strategy involves modifying the AAV capsid by attaching various moieties. The capsid of AAV plays a pivotal role in transducing target cells and evading immune responses, making modifications a key avenue for engineering improved variants. RESULTS: In our study, we replaced specific AAV9 capsid residues with an unnatural amino acid bearing a bioorthogonal group, identifying four positions with no adverse impact on production. Utilizing click chemistry, we attached varying proportions of Cy5.5 to these positions, allowing us to assess the impact of these modifications on AAV9 infectivity in cultured cells. Our findings reveal that both the position and degree of capsid modification significantly affect AAV transduction. While higher amounts of attached molecules lead to an increased number of AAV genomes within cells, this does not positively impact transgene expression. Conversely, a negative impact on transgene expression is observed when the AAV capsid is highly modified, with the degree of this effect associated with the modified residue. CONCLUSION: Careful control of both the degree and specific position of capsid modifications is crucial for optimizing transduction efficiency and minimizing undesired effects on transgene expression. These results underscore the importance of precision in AAV capsid modification to achieve optimal transduction efficiency while mitigating potential drawbacks on transgene expression.

Increased glutamatergic neurotransmission between the retinohypothalamic tract and the suprachiasmatic nucleus of old mice.

Circadian rhythms synchronize to light through the retinohypothalamic tract (RHT), which is a bundle of axons coming from melanopsin retinal ganglion cells, whose synaptic terminals release glutamate to the ventral suprachiasmatic nucleus (SCN). Activation of AMPA-kainate and NMDA postsynaptic receptors elicits the increase in intracellular calcium required for triggering the signaling cascade that ends in phase shifts. During aging, there is a decline in the synchronization of circadian rhythms to light. With electrophysiological (whole-cell patch-clamp) and immunohistochemical assays, in this work, we studied pre- and postsynaptic properties between the RHT and ventral SCN neurons in young adult (P90-120) and old (P540-650) C57BL/6J mice. Incremental stimulation intensities (applied on the optic chiasm) induced much lesser AMPA-kainate postsynaptic responses in old animals, implying a lower recruitment of RHT fibers. Conversely, a higher proportion of old SCN neurons exhibited synaptic facilitation, and variance-mean analysis indicated an increase in the probability of release in RHT terminals. Moreover, both spontaneous and miniature postsynaptic events displayed larger amplitudes in neurons from aged mice, whereas analysis of the NMDA and AMPA-kainate components (evoked by RHT electrical stimulation) disclosed no difference between the two ages studied. Immunohistochemistry revealed a bigger size in the puncta of vGluT2, GluN2B, and GluN2A of elderly animals, and the number of immunopositive particles was increased, but that of PSD-95 was reduced. All these synaptic adaptations could be part of compensatory mechanisms in the glutamatergic signaling to ameliorate the loss of RHT terminals in old animals.

(Pro)renin receptor signaling in hypothalamic tyrosine hydroxylase neurons is required for obesity-associated glucose metabolic impairment.

Glucose homeostasis is achieved via complex interactions between the endocrine pancreas and other peripheral tissues and glucoregulatory neurocircuits in the brain that remain incompletely defined. Within the brain, neurons in the hypothalamus appear to play a particularly important role. Consistent with this notion, we report evidence that (pro)renin receptor (PRR) signaling within a subset of tyrosine hydroxylase (TH) neurons located in the hypothalamic paraventricular nucleus (PVNTH neurons) is a physiological determinant of the defended blood glucose level. Specifically, we demonstrate that PRR deletion from PVNTH neurons restores normal glucose homeostasis in mice with diet-induced obesity (DIO). Conversely, chemogenetic inhibition of PVNTH neurons mimics the deleterious effect of DIO on glucose. Combined with our finding that PRR activation inhibits PVNTH neurons, these findings suggest that, in mice, (a) PVNTH neurons play a physiological role in glucose homeostasis, (b) PRR activation impairs glucose homeostasis by inhibiting these neurons, and (c) this mechanism plays a causal role in obesity-associated metabolic impairment.

Cancer-Related Fatigue and Circulating Biomarkers in Breast Cancer Survivors.

PURPOSE: Cancer-related fatigue (CRF) is the most common and disruptive symptom experienced by cancer survivors and because of its frequency and severity is especially worrisome in breast cancer survivors (BCS). Despite a great deal of research, the mechanisms underlying CRF have not been determined. The present study aims to describe associations between CRF in BCS and different blood biomarkers. METHODS: A descriptive and cross-sectional study was conducted. A set of biomarkers assessing inflammation were measured in BCS: C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), IL-1ß, IL-6, IL-8, IL-10, tumor necrosis factor (TNF); HPA axis dysfunction (cortisol), autonomic dysfunction (noradrenaline); oxidative stress (8-OH deoxyguanosine); insulin resistance markers (insulin, IGF-I, IGFBP3) and sexual hormones (estrogens, progesterone, testosterone). RESULTS: NLR (p = .00) and cortisol (p = .02) were positive and negatively associated with CRF, respectively. The rest of the blood markers were not associated with CRF. CONCLUSION: Our results increase the evidence on pathophysiological mechanisms driving CRF in BCS. However, longitudinal studies are needed to explore the role of these factors as potential causal mechanisms.

Sexual dysfunction in patients with cancer, a challenge in oncology practice: results of the CLARIFY project.

BACKGROUND: Sexual dysfunction (SD) associated with oncological treatment is a common and understudied disorder. Our aim was to characterize SD in a cohort of Spanish patients. METHODS: Analytic observational study in patients included in the CLARIFY H2020 project at the Hospital Universitario Puerta de Hierro. Clinical variables and validated measures of sexual function were collected from October 2020 to May 2022. Frequency and quality of sexual activity were assessed. Descriptive, trend associations, and logistic regression analyses were performed. RESULTS: A total of 383 patients were included: breast cancer 68.14% (261), lung cancer 26.37% (101), and lymphoma 5.50% (21). Mean age was 56.5 years (range 33-88). 19.58% (75) were men and 80.42% (308) were women. 69% and 31% of men and women, respectively, reported being sexually active. The absolute frequency of overall sexual dissatisfaction was 76% in women and 24% in men. Women with breast cancer were most likely to have severe sexual dysfunction. Those with early disease had resolved complaints after 5 years. In multinomial logistic regression, significant associations were found in women with metastatic breast cancer and severe disorders of arousal (p 0.000), lubrication (p 0.002), orgasm (p 0.000), as well as dissatisfaction with sexual performance (p 0.000) and global sexual dissatisfaction (p 0.000). Women with lung cancer have severe arousal dysfunction (p 0.016) and global sexual dissatisfaction (p 0.044). CONCLUSIONS: Our population has a high prevalence of SD, which supports the need to increase awareness of this disorder among the medical oncology team and the importance of including sexual health assessment in oncological patient follow-up.

A genetic profiling guideline to support diagnosis and clinical management of lymphomas.

The new lymphoma classifications (International Consensus Classification of Mature Lymphoid Neoplasms, and 5th World Health Organization Classification of Lymphoid Neoplasms) include genetics as an integral part of lymphoma diagnosis, allowing better lymphoma subclassification, patient risk stratification, and prediction of treatment response. Lymphomas are characterized by very few recurrent and disease-specific mutations, and most entities have a heterogenous genetic landscape with a long tail of recurrently mutated genes. Most of these occur at low frequencies, reflecting the clinical heterogeneity of lymphomas. Multiple studies have identified genetic markers that improve diagnostics and prognostication, and next-generation sequencing is becoming an essential tool in the clinical laboratory. This review provides a "next-generation sequencing" guide for lymphomas. It discusses the genetic alterations of the most frequent mature lymphoma entities with diagnostic, prognostic, and predictive potential and proposes targeted sequencing panels to detect mutations and copy-number alterations for B- and NK/T-cell lymphomas.

Patterns and outcome of unplanned care in lung cancer patients: an observational study in a medical oncology department.

Background: There is increasing interest in unplanned care utilization among lung cancer patients and its evaluation should allow the identification of areas for quality improvement. Being a major priority for transformation in oncology, we aim to measure the risk and burden of unplanned care in a medical oncology department and identify factors that determine acute care. Methods: This was an observational retrospective cohort study that included all lung cancer patients treated at Puerta de Hierro-Majadahonda University Hospital between January 1st 2016 and December 31st 2020. Data cut off: June 30th, 2021. The main objective was to assess the incidence of unplanned care, emergency department (ED) visits and unplanned hospital admissions, from the first visit to the medical oncology service and its potential conditioning variables, considering patient death as a competitive event. As secondary objectives, a description and a quality of unplanned care evaluation was carried out. Results: A total of 821 lung cancer patients, all histologies and stages, were included (median follow-up: 32.8 months). Six hundred and eighty-one patients required consultation in the ED (82.9%), and 558 required an unplanned admission (68%). Eighty-six percent of ED consultations and 80.9% of unplanned hospital admissions were related to cancer or its treatment. The 1-year cumulative incidence for ED consultation and for unplanned hospital admission was 71.3% (95% CI: 67.8-74.5%) and 56.7% (95% CI: 53-60%), respectively. In the multivariable analysis, a higher tumor stage increased the risk of consultation in the ED, while a higher stage, Eastern Cooperative Oncology Group performance status (ECOG PS) 2 compared to ECOG PS 0, male sex, opioid or steroid use at first consultation increased the risk of unplanned admission. Conclusions: Our study shows that lung cancer patients have an extremely high demand for unplanned care. It is an early need and related to cancer in the majority of consultations and admissions and therefore a key issue for the management of oncology departments. We must optimize the follow-up of patients with a higher risk of unplanned care, advanced lung cancer or symptomatic patients, incorporating remote monitoring strategies and early interventions, as developing specific urgent care pathways for a better comprehensive cancer care.

Needs of patients with multi-morbidity and heart failure for the development of a mHealth to improve their self-management: A qualitative analysis.

Objective: To provide practical information regarding needs, preferences of content and format of an app to assist the self-management in patients with multi-morbidity and heart failure (HF). Methods: The three-phase study was conducted in Spain. Six integrative reviews, a qualitative methodology based on Van Manen's hermeneutic phenomenology through semi-structured interviews and user stories were used. Data collection continued until data saturation was reached. All data were transcribed verbatim and analysed using a framework approach. Thematic analysis technique following the methods of Braun and Clarke was used for emerging themes. Results: Integrative reviews conducted included practical recommendations to include in the content and format of the App and helped create the interview guide. Interviews revealed 15 subthemes that captured the meaning of narratives offering contextual insights into the development of the App. The main effective mechanisms of multicomponent interventions for patients with HF must contain (a) components that increase the patient's understanding of HF, (b) self-care, (c) self-efficacy and participation of the family/informal caregiver, (4) psychosocial well-being and (5) professional support and use of technology. User stories revealed that patients prioritized improvements in direct contact with health services in case of emergency (90%), nutritional information (70%), type of exercises in order to improve their physical condition (75%) and information about food and drug interaction (60%). The importance of motivation messages (60%) was highlighted by transversal way. Conclusions: The three-phase process integrating theoretical basis, evidence from integrative reviews and research findings from target users has been considered a guide for future app development.

Intervention programme to improve knowledge, attitudes, and behaviour of nursing students towards organ donation and transplantation: A randomised controlled trial.

AIM: To develop and evaluate an educational programme aimed at undergraduate training to increase and improve knowledge, attitudes and behaviour towards the organ and tissue donation and transplants (OTDT). BACKGROUND: The request for OTDT falls on the health personnel and the reduction of family refusals depends on their attitude and competence, which is vital to increase OTDT. The evidence highlights the efficacy of starting training at early stages and the implementation of educational programmes in universities is recommended to reduce family refusals. DESIGN: A randomised controlled trial. METHODS: A randomised controlled trial with an experimental group (EG) -theory class and round table- and a control group (CG) -theory class- that transitions to a delayed experimental group. A sample of 73 students was distributed in parallel randomised groups. RESULTS: The groups increased their knowledge and improved their attitude, significantly changing their behaviour in the follow-up. These changes in the experimental groups were more significant than in CG in perceived quality of information (z = -4.948; p = <0.001), level of knowledge (EG1 and CG z = -2.245; p = 0.025) (EG2 and CG z = -2.215; p = 0.027), attitude (EG1 and CG z = -2.687; p = 0.007) (EG2 and CG z = -2.198; p = 0.028) and behaviour (EG1 and CG t = 2.054; p = 0.044) (EG2 and CG z = -2.797; p = 0.005). CONCLUSIONS: The education programme has proven effective, promoting knowledge, change and entrenchment of attitudes, facilitating conversations with families, enabling willingness to donate and increasing potential donors.

Long-term outcomes in Hodgkin lymphoma survivors. Temporary trends and comparison with general population.

The high cure rates of Hodgkin lymphoma (HL) make this oncological disease among those with the greatest number of long-term survivors. This single-institution study including 383 HL patients with up to 45 years of follow-up, analyses the morbidity and mortality of this population after treatments in comparison with the overall Spanish population, and investigates whether it has changed over time stratifying by periods of time, as a consequence of therapeutic optimization. The median age was 34.8 years (range 15-87) with median overall survival of 30 years, significantly higher in women (HR 0.58, 95% CI 0.42-0.79) (p = 0.0002). 185 late-stage diseases were noted (35% patients), cardiovascular disease (CVD) being the most frequent (23.2%). 30% of patients developed at least one second malignant neoplasm (SMN) to give a total of 174 SMNs. 20.9% of the patients died from HL and 67.0% died from non-HL causes (32.2% from SMN, 17% from CVD). The overall standardized mortality ratio (SMR) was 3.57 (95% CI: 3.0-4.2), with striking values of 7.73 (95% CI: 5.02-8.69) and of 14.75 (95% CI: 11.38-19.12) for women and patients <30 years at diagnosis, respectively. Excluding HL as the cause of death, the SMRs of those diagnosed before 2000 and from 2000 were proved to be similar (3.88 vs 2.73), maintaining in this last period an unacceptable excess of mortality due to secondary toxicity in patients cured of HL. Our study confirm that HL treatment substantially reduces the life expectancy of patients cured of HL. In recent periods, despite therapeutic optimization, deaths from toxicity continue to occur, mainly from CVD and SMN. Risk-factor monitoring should be intensified, prevention programs developed, and therapeutic optimization of LH investigated, especially in two vulnerable groups: those aged <30 years at diagnosis, and women.

Content and Clinical Validation of the Nursing Outcome "Health Literacy Behaviour": A Validation Protocol.

Health literacy (HL) is a result of health promotion and education that has been included as a nursing intervention since 2013. It was proposed, as a nursing activity, to "determine health literacy status at initiation of contact with the patient through informal and/or formal assessments". Because of that, the outcome 'Health Literacy Behaviour' has been incorporated in the sixth edition of the Nursing Outcomes Classification (NOC). It collects the patient's different HL levels and allows them to be identified and evaluated in a social and health context. Nursing outcomes are helpful and provide relevant information for the evaluation of nursing interventions. OBJECTIVES: To validate the contents of the nursing outcome 'Health Literacy Behaviour (2015)' in order to use them in nursing care plans, and to evaluate their psychometric properties, application level, and effectiveness in nursing care to detect low health literacy patients. METHODS: a methodological two-phased study: (1) an exploratory study and content validation by expert consensus, who will evaluate revised content of nursing outcomes; (2) methodological design by clinical validation. CONCLUSION: The validation of this nursing outcome in NOC will enable the generation of a helpful tool that would facilitate nurses to set individualised and efficient care interventions and identify low health literacy populations.

Knowledge, Attitudes and Behaviours of Adolescents and Young Adult Population on the Use of E-Cigarettes or Personal Vaporizer.

The use of electronic cigarettes (e-cig) or personal vaporizers (PV) has increased in recent years, especially among adolescents and adults, increasing risk factors for their health or being a starting point for other risk behaviours. The aim of our study is to learn the knowledge, attitudes and behaviours of the adolescent and young adult population on the use of e-cigarettes or PVs. A cross-sectional descriptive study was carried out among 375 subjects. The use of e-cigs or PVs was measured using a self-administered questionnaire. Overall, 13.33% of the respondents used e-cigarettes or PVs. A correlation could be established between vape use and age, with 14-18-year-olds being the highest users (25.9%). Additionally, 90.13% of the respondents answered that e-cig or PV use was harmful to health. Other behaviours, such as consumption of energy drinks (ED), increases the probability of vaping by 3.08 times (CI = 1.55-6.29; p = 0.001). Subjects aged 23-26 years and 27-34 years are less likely to vape than subjects aged 14-18 years (OR = 0.31: CI = 0.09-0.96; p = 0.044; OR = 0.07: CI = 0.00-0.63; p = 0.037).
