Detection of NT-proBNP Using Optical Fiber Back-Reflection Plasmonic Biosensors.

Heart failure (HF) is a clinical entity included in cardiovascular diseases affecting millions of people worldwide, being a leading cause of hospitalization of older adults, and therefore imposing a substantial economic burden on healthcare systems. HF is characterized by dyspnea, fatigue, and edema associated with elevated blood levels of natriuretic peptides, such as N Terminal pro-B-type Natriuretic Peptide (NT-proBNP), for which there is a high demand for point of care testing (POCT) devices. Optical fiber (OF) biosensors offer a promising solution, capable of real-time detection, quantification, and monitoring of NT-proBNP concentrations in serum, saliva, or urine. In this study, immunosensors based on plasmonic uncladded OF tips were developed using OF with different core diameters (200 and 600 µm). The tips were characterized to bulk refractive index (RI), anddetection tests were conducted with NT-proBNP concentrations varying from 0.01 to 100 ng/mL. The 200 µm sensors showed an average total variation of 3.6 ± 2.5 mRIU, an average sensitivity of 50.5 mRIU/ng·mL-1, and a limit of detection (LOD) of 0.15 ng/mL, while the 600 µm sensors had a response of 6.1 ± 4.2 mRIU, a sensitivity of 102.8 mRIU/ng·mL-1, and an LOD of 0.11 ng/mL. Control tests were performed using interferents such as uric acid, glucose, and creatinine. The results show the potential of these sensors for their use in biological fluids.

Diagnostic Accuracy of Cone Beam Computed Tomography and Periapical Radiography for Detecting Apical Root Resorption in Retention Phase of Orthodontic Patients: A Cross-Sectional Study.

Objectives: This clinical study aimed to evaluate and compare the diagnostic accuracy of intraoral periapical radiography (PR) and cone beam computed tomography (CBCT) in detecting external apical root resorption (EARR) in orthodontic patients during the retention phase. Methods: The research involved 41 Caucasian patients who had undergone comprehensive orthodontic treatment, with a total of 328 teeth analyzed. The Kappa values for inter- and intra-examiner agreement were high for both PR and CBCT, indicating a robust level of agreement among examiners. The study used a four-point scale for classifying EARR. Results: This study showed comparable accuracy, sensitivity, and specificity between PR and CBCT when using the most stringent criterion of "Definitely present". The data suggested that CBCT outperformed PR when using a less stringent criterion ("Definitely present" or "Probably present"), particularly for maxillary incisors. However, overall diagnostic performance, as measured by the area under the ROC curve, showed only a slight advantage for CBCT over PR. Areas under the ROC curve range between 0.85 and 0.90 for PR and between 0.89 and 0.92 for CBCT. According to DeLong's test, there is no evidence to conclude that the area under the ROC curve is different for PR and CBCT. Conclusions: Both PR and CBCT are accurate diagnostic tools for identifying EARR, with PR being deemed more suitable for routine clinical use due to its cost-effectiveness and lower radiation exposure. The findings emphasize the importance of considering the risk-benefit ratio when deciding on imaging modalities for monitoring EARR in orthodontic patients.

Bacteria: Potential Make-or-Break Determinants of Celiac Disease.

Celiac disease is an autoimmune disease triggered by dietary gluten in genetically susceptible individuals that primarily affects the small intestinal mucosa. The sole treatment is a gluten-free diet that places a social and economic burden on patients and fails, in some, to lead to symptomatic or mucosal healing. Thus, an alternative treatment has long been sought after. Clinical studies on celiac disease have shown an association between the presence of certain microbes and disease outcomes. However, the mechanisms that underlie the effects of microbes in celiac disease remain unclear. Recent studies have employed disease models that have provided insights into disease mechanisms possibly mediated by bacteria in celiac disease. Here, we have reviewed the bacteria and related mechanisms identified so far that might protect from or incite the development of celiac disease. Evidence indicates bacteria play a role in celiac disease and it is worth continuing to explore this, particularly since few studies, to the best of our knowledge, have focused on establishing a mechanistic link between bacteria and celiac disease. Uncovering host-microbe interactions and their influence on host responses to gluten may enable the discovery of pathogenic targets and development of new therapeutic or preventive approaches.

Intravesical Ty21a treatment of non-muscle invasive bladder cancer induces immune responses that correlate with safety and may be associated to therapy potential.

BACKGROUND: Standard of care treatment of non-muscle invasive bladder cancer (NMIBC) with intravesical Bacillus Calmette Guérin (BCG) is associated with side effects, disease recurrence/progression and supply shortages. We recently showed in a phase I trial (NCT03421236) that intravesical instillation in patients with NMIBC with the maximal tolerated dose of Ty21a/Vivotif, the oral vaccine against typhoid fever, might have a better safety profile. In the present report, we assessed the immunogenicity of intravesical Ty21a in patients of the clinical trial that had received the maximal tolerated dose and compared it with data obtained in patients that had received standard BCG. METHODS: Urinary cytokines and immune cells of patients with NMIBC treated with intravesical instillations of Ty21a (n=13, groups A and F in NCT03421236) or with standard BCG in a concomitant observational study (n=12, UROV1) were determined by Luminex and flow cytometry, respectively. Serum anti-lipopolysaccharide Typhi antibodies and circulating Ty21a-specific T-cell responses were also determined in the Ty21a patients. Multiple comparisons of different paired variables were performed with a mixed-effect analysis, followed by Sidak post-test. Single comparisons were performed with a paired or an unpaired Student's t-test. RESULTS: As compared with BCG, Ty21a induced lower levels of inflammatory urinary cytokines, which correlated to the milder adverse events (AEs) observed in Ty21a patients. However, both Ty21a and BCG induced a Th1 tumor environment. Peripheral Ty21a-specific T-cell responses and/or antibodies were observed in most Ty21a patients, pointing the bladder as an efficient local immune inductive site. Besides, Ty21a-mediated stimulation of unconventional Vδ2 T cells was also observed, which turned out more efficient than BCG. Finally, few Ty21a instillations were sufficient for increasing urinary infiltration of dendritic cells and T cells, which were previously associated with therapeutic efficacy in the orthotopic mouse model of NMIBC. CONCLUSIONS: Ty21a immunotherapy of patient with NMIBC is promising with fewer inflammatory cytokines and mild AE, but induction of immune responses with possible antitumor potentials. Future phase II clinical trials are necessary to explore possible efficacy of intravesical Ty21a.

Centriolar subdistal appendages promote double-strand break repair through homologous recombination.

The centrosome is a cytoplasmic organelle with roles in microtubule organization that has also been proposed to act as a hub for cellular signaling. Some centrosomal components are required for full activation of the DNA damage response. However, whether the centrosome regulates specific DNA repair pathways is not known. Here, we show that centrosome presence is required to fully activate recombination, specifically to completely license its initial step, the so-called DNA end resection. Furthermore, we identify a centriolar structure, the subdistal appendages, and a specific factor, CEP170, as the critical centrosomal component involved in the regulation of recombination and resection. Cells lacking centrosomes or depleted for CEP170 are, consequently, hypersensitive to DNA damaging agents. Moreover, low levels of CEP170 in multiple cancer types correlate with an increase of the mutation burden associated with specific mutational signatures and a better prognosis, suggesting that changes in CEP170 can act as a mutation driver but could also be targeted to improve current oncological treatments.

Outdoor airborne allergens: Characterization, behavior and monitoring in Europe.

Aeroallergens or inhalant allergens, are proteins dispersed through the air and have the potential to induce allergic conditions such as rhinitis, conjunctivitis, and asthma. Outdoor aeroallergens are found predominantly in pollen grains and fungal spores, which are allergen carriers. Aeroallergens from pollen and fungi have seasonal emission patterns that correlate with plant pollination and fungal sporulation and are strongly associated with atmospheric weather conditions. They are released when allergen carriers come in contact with the respiratory system, e.g. the nasal mucosa. In addition, due to the rupture of allergen carriers, airborne allergen molecules may be released directly into the air in the form of micronic and submicronic particles (cytoplasmic debris, cell wall fragments, droplets etc.) or adhered onto other airborne particulate matter. Therefore, aeroallergen detection strategies must consider, in addition to the allergen carriers, the allergen molecules themselves. This review article aims to present the current knowledge on inhalant allergens in the outdoor environment, their structure, localization, and factors affecting their production, transformation, release or degradation. In addition, methods for collecting and quantifying aeroallergens are listed and thoroughly discussed. Finally, the knowledge gaps, challenges and implications associated with aeroallergen analysis are described.

HTA and Reimbursement Status of Metastatic Hormone­Sensitive Prostate Cancer, Non-Metastatic Castration-Resistant Prostate Cancer, and Metastatic Castration-Resistant Prostate Cancer Treatments in Europe: A Patient Access Landscape Review.

Background: Prostate cancer is the second most common cancer in men, with up to one-third of men being diagnosed in their lifetime. Recently, novel therapies have received regulatory approval with significant improvement in overall survival for metastatic castration-resistant prostate cancer, metastatic hormone-sensitive prostate cancer, and nonmetastatic castration-resistant prostate cancer. To improve decision-making regarding the value of anticancer therapies and support standardized assessment for use by health technology assessment (HTA) agencies, the European Society for Medical Oncology (ESMO) has developed a Magnitude of Clinical Benefit Scale (MCBS). Objective: This review aimed to map HTA status, reimbursement restrictions, and patient access for 3 advanced prostate cancer indications across 23 European countries during 2011-2021. Methods: HTA, country reimbursement lists, and ESMO-MCBS scorecards were reviewed for evidence and data across 26 European countries. Results: The analysis demonstrated that only in Greece, Germany, and Sweden was there full access across all included prostate cancer treatments. Treatments available for metastatic castration-resistant prostate cancer were widely reimbursed, with both abiraterone and enzalutamide accessible in all countries. In 3 countries (Hungary, the Netherlands, and Switzerland), there was a statistically significant difference (P<.05) between status of reimbursement and ESMO-MCBS "substantial benefit" (score of 4 or 5) vs "no substantial benefit" (score <4). Conclusion: Overall, the impact of the ESMO-MCBS on reimbursement decisions in Europe is unclear, with significant variation across the countries included in this review.

Stent as bridge to surgery decreases postoperative complications without worsening oncological outcomes: retrospective unicentric cohort study and stent placement protocol.

BACKGROUND: Even if the use of stent as bridge to surgery (BTS) for obstructive colon cancer was described long ago, there is still much controversy on their use. Patient recovery before surgery and colonic desobstruction are just some of the reasons to defend this management that can be found in several available articles. METHODS: This is a single-center, retrospective cohort study, including patients with obstructive colon cancer treated between 2010 and 2020. The primary aim of this study is to compare medium-term oncological outcomes (overall survival, disease-free survival) between stent as BTS and ES groups. The secondary aims are to compare perioperative results (in terms of approach, morbidity and mortality, and rate of anastomosis/stomas) between both groups and, within the BTS group, analyze whether there are any factors that may influence oncological outcomes. RESULTS: A total of 251 patients were included. Patients belonging to the BTS cohort presented a higher rate of laparoscopic approach, required less intensive care management, less reintervention, and less permanent stoma rate, when comparing with patients who underwent urgent surgery (US). There were not significant differences in terms of disease-free survival and overall survival between the two groups. Lymphovascular invasion negatively affected oncological results but was not related with stent placement. CONCLUSION: The stent as a bridge to surgery is a good alternative to urgent surgery, which leads to a decrease in postoperative morbidity and mortality without significantly worsening oncological outcomes.

Health outcomes and budget impact projection of anti-PD-(L)1s in cancer care in Portugal.

Introduction: PD-[L]1 inhibitors revolutionized cancer treatment but challenge the affordability of health systems. This policy-focused model aimed to estimate the health and budget impact of anti-PD-(L)1s in Portugal and inform current discussions. Materials and methods: The Health Impact Projection (HIP) model estimates clinical (life years, progression-free survival [PFS] years, and quality-adjusted life years [QALY] gained and adverse events [AEs] incurred) and economic (direct and indirect costs) outcomes in a world where cancer patients are initiating treatment with standard-of-care (SOC) versus SOC plus anti-PD-(L)1s over a 3-year time horizon. Indications included adjuvant and metastatic melanoma, non-small cell lung cancer (first and second line), metastatic triple-negative breast cancer, head and neck cancer, urothelial carcinoma, and renal cell carcinoma. Model inputs were based on publicly available literature data and expert opinion. Results: The model estimated that, over 3 years, 7,773 patients would be treated with anti-PD-(L)1s, realizing a gain of 4,787 life years, 6,901 PFS years, and 4,214 QALYs and avoiding 399 AEs. The introduction of anti-PD-(L)1s had a projected average annual impact of ≈ €108 million and a share of 20% of total cancer medicines expenditure and 0.6% of total healthcare expenditure in 2021. Although higher disease management costs are expected for patients living longer with anti-PD-(L)1s and drug acquisition costs are considerable, that is partially offset by a reduction in end-of-life costs (€611,092/year) and costs associated with patient productivity lost to cancer (€9,128,142/year). Discussion: This model highlights the significant survival and QoL benefit of anti-PD-(L)1s for cancer patients in Portugal, with a relatively low increased cost in total healthcare expenditure.

BUPROPION MISUSE BY NASAL INSUFFLATION WITH A FATAL OUTCOME: CASE REPORT AND REVIEW.

Bupropion is the only FDA - approved synthetic cathinone, with increasing popularity in clinical practice due to its wide range of action, and lack of sexual side effects. However, its stimulant effect similar to amphetamines has growing the concern regarding its recreational use.

Uso indebido de bupropión por insuflación nasal con desenlace fatal: reporte de un caso y revisión / Abuse of bupropion by nasal insufflation with fatal outcome: report of a case and review

Introducción. El bupropión es la única catinona sintética aprobada por la FDA, con una creciente popularidad en la práctica clínica debido a su amplio rango de acción y la falta de efectos secundarios sexuales. Sin embargo, su efecto estimulante similar al de las anfetaminas ha hecho crecer la preocupación respecto a su uso recreativo. Objetivos y métodos. En este manuscrito informamos un caso de uso indebido de bupropión mediante insuflación nasal con desenlace fatal y realizamos una breve revisión deluso recreativo de bupropión. Resultados. Presentamos el caso de un hombre de unos50 años, con abuso prolongado de bupropión principalmente por insuflación nasal, que falleció súbitamente unas dos semanas después de ser dado de alta por un infarto agudo de miocardio tipo 2 secundario a sobredosis de bupropión. A lo largo de las últimas décadas, varios estudios han informado un uso indebido cada vez mayor de bupropión por vías no orales, especialmente a través de la insuflación nasal, y el uso intravenoso, particularmente en pacientes con antecedentes de abuso de sustancias, adolescentes o en entornos penitenciarios. A pesar de que la mayoría de los pacientes tienen efectos secundarios de leves a moderados, consecuencias devastadoras, tales como convulsiones refractarias o shock cardiogénico refractario, pueden ocurrir en caso de sobredosis, lo que exige un reconocimiento oportuno y un enfoque rápido para prevenir estos resultados importantes. En caso de sobredosis, no existe un antídoto específico disponible ni un tratamiento curativo aprobado, su manejo se centra en el tratamiento de los síntomas. Conclusiones. El bupropión es un antidepresivo eficaz, sin embargo, tiene potencial para uso recreativo, especialmente en grupos de alto riesgo. Este documento alerta a todos los médicos sobre el problema emergente relacionado con el uso indebido de bupropión y agrega algunas ideas sobre su reconocimiento y manejo oportunos. (AU)

Patterns of Medication Management and Associated Medical and Clinical Features among Home-Dwelling Older Adults: A Cross-Sectional Study in Central Portugal.

Ageing is frequently associated with multimorbidity and polypharmacy. The present study aimed to identify the current medication management patterns and the profiles of home-dwelling older adults and to find any association with their conditions, including frailty and cognitive impairment. Within the scope of this cross-sectional study, 112 older adults living in the community were assessed via face-to-face structured interviews. Frailty, cognitive status, medication management and clinical and sociodemographic variables were evaluated. Descriptive and inferential statistics were calculated. The mean participant age was 76.6 ± 7.1 years, 53.6% of participants were women, and 40.2% of participants lived alone. More than half were classified as having frailty (58.9%), almost one-fifth (19.6%) presented with a moderate cognitive impairment had more than one disease, and 60.7% were polymedicated. No associations were found between polymedication and medication self-management, the use of over-the-counter medications, living alone, having a poor understanding of pharmacological therapy and/or pathology, or having more than one prescriber. Self-management was associated with age, the number of medications, frailty and cognitive status. Binary logistic regressions showed that cognitive impairment had statistically significant differences with medication management, having a poor understanding of pharmacological therapy and/or pathology, having one prescriber and the use of medications not prescribed by physicians. Interventions to prevent medication-related problems in home-dwelling older adults are recommended.

Primary Hyperparathyroidism in a Post-total Thyroidectomy Patient: An Unexpected Diagnosis.

Hypercalcemia is commonly encountered in the clinical setting. Although primary hyperparathyroidism resulting from a single parathyroid adenoma is the most common cause, in patients who undergo total thyroidectomy, especially when there is no history of radiation exposure nor parathyroid autotransplantation, it becomes an even more unexpected diagnosis. Because the majority of patients are asymptomatic, the diagnosis often is made incidentally. However, with long-standing disease, as parathyroid hormone and blood calcium levels rise, symptoms become more noticeable, and its clinical manifestations can affect nearly every organ system in the body. We present the case of a 79-year-old woman with a history of surgical hypothyroidism secondary to total thyroidectomy, hypertension and chronic kidney disease, who was admitted to the Emergency Department after an episode of syncope. She mentioned abdominal pain and vomiting in the previous week and paresthesia of both hands and feet over the last months. The initial testing identified a first-degree auriculoventricular block, a worsened renal function and severe hypercalcemia caused by primary hyperparathyroidism. The mainstay of treatment was aggressive fluid therapy, intravenous bisphosphonate and calcimimetic. Definitive treatment was achieved by the surgical removal of a mass located in the left thyroidectomy bed, compatible with a parathyroid adenoma. No further therapy was needed, as calcium levels gradually returned to normal.

An Intervention Program to Reduce Medication-Related Problems Among Polymedicated Home-Dwelling Older Adults (OptiMed): Protocol for a Pre-Post, Multisite, Pilot, and Feasibility Study.

BACKGROUND: Effective medication management is one of the essential preconditions for enabling polymedicated home-dwelling older adults with multiple chronic conditions to remain at home and preserve their quality of life and autonomy. Lack of effective medication management predisposes older adults to medication-related problems (MRPs) and adverse health outcomes, which can lead to the degradation of a patient's acute clinical condition, physical and cognitive decline, exacerbation of chronic medical conditions, and avoidable health care costs. Nonetheless, it has been shown that MRPs can be prevented or reduced by using well-coordinated, patient-centered, interprofessional primary care interventions. OBJECTIVE: This study aimed to explore the feasibility and acceptability of an evidence-based, multicomponent, interprofessional intervention program supported by informal caregivers to decrease MRPs among polymedicated home-dwelling older adults with multiple chronic conditions. METHODS: This quasi-experimental, pre-post, multisite pilot, and feasibility study will use an open-label design, with participants knowing the study's objectives and relevant information, and it will take place in primary health care settings in Portugal and Switzerland. The research population will comprise 30 polymedicated, home-dwelling adults, aged ≥65 years at risk of MRPs and receiving community-based health care, along with their informal caregivers and health care professionals. RESULTS: Before a projected full-scale study, this pilot and feasibility study will focus on recruiting and ensuring the active collaboration of its participants and on the feasibility of expanding this evidence-based, multicomponent, interprofessional intervention program throughout both study regions. This study will also be essential to projected follow-up research programs on informal caregivers' multiple roles, enhancing their coordination tasks and their own needs. Results are expected at the end of 2024. CONCLUSIONS: Designing, establishing, and exploring the feasibility and acceptability of an intervention program to reduce the risks of MRPs among home-dwelling older adults is an underinvestigated issue. Doing so in collaboration with all the different actors involved in that population's medication management and recording the first effects of the intervention will make this pilot and feasibility study's findings very valuable as home care becomes an ever more common solution.

Detection of Patients at Risk of Multidrug-Resistant Enterobacteriaceae Infection Using Graph Neural Networks: A Retrospective Study.

Background: While Enterobacteriaceae bacteria are commonly found in the healthy human gut, their colonization of other body parts can potentially evolve into serious infections and health threats. We investigate a graph-based machine learning model to predict risks of inpatient colonization by multidrug-resistant (MDR) Enterobacteriaceae. Methods: Colonization prediction was defined as a binary task, where the goal is to predict whether a patient is colonized by MDR Enterobacteriaceae in an undesirable body part during their hospital stay. To capture topological features, interactions among patients and healthcare workers were modeled using a graph structure, where patients are described by nodes and their interactions are described by edges. Then, a graph neural network (GNN) model was trained to learn colonization patterns from the patient network enriched with clinical and spatiotemporal features. Results: The GNN model achieves performance between 0.91 and 0.96 area under the receiver operating characteristic curve (AUROC) when trained in inductive and transductive settings, respectively, up to 8% above a logistic regression baseline (0.88). Comparing network topologies, the configuration considering ward-related edges (0.91 inductive, 0.96 transductive) outperforms the configurations considering caregiver-related edges (0.88, 0.89) and both types of edges (0.90, 0.94). For the top 3 most prevalent MDR Enterobacteriaceae, the AUROC varies from 0.94 for Citrobacter freundii up to 0.98 for Enterobacter cloacae using the best-performing GNN model. Conclusion: Topological features via graph modeling improve the performance of machine learning models for Enterobacteriaceae colonization prediction. GNNs could be used to support infection prevention and control programs to detect patients at risk of colonization by MDR Enterobacteriaceae and other bacteria families.

Type 2 innate lymphoid cells are not involved in mouse bladder tumor development.

Therapies for bladder cancer patients are limited by side effects and failures, highlighting the need for novel targets to improve disease management. Given the emerging evidence highlighting the key role of innate lymphoid cell subsets, especially type 2 innate lymphoid cells (ILC2s), in shaping the tumor microenvironment and immune responses, we investigated the contribution of ILC2s in bladder tumor development. Using the orthotopic murine MB49 bladder tumor model, we found a strong enrichment of ILC2s in the bladder under steady-state conditions, comparable to that in the lung. However, as tumors grew, we observed an increase in ILC1s but no changes in ILC2s. Targeting ILC2s by blocking IL-4/IL-13 signaling pathways, IL-5, or IL-33 receptor, or using IL-33-deficient or ILC2-deficient mice, did not affect mice survival following bladder tumor implantation. Overall, these results suggest that ILC2s do not contribute significantly to bladder tumor development, yet further investigations are required to confirm these results in bladder cancer patients.

A pessoa com baixa autoestima: utilização de mediadores expressivos pelo enfermeiro especialista / The person with low self-esteem: use of expressive mediators by specialist nurses

A autoestima corresponde à perceção e avaliação que cada um faz de si, interferindo com todas as dimensões da experiência pessoal. É um processo dinâmico, contínuo e estruturado desde a infância, consequente de experiências que decorrem do relacionamento com a família, pares e sociedade, sujeito a alterações ao longo da vida. Com repercussões na vida afetiva, social, no bem-estar e qualidade de vida, corresponde a um indicador de saúde mental. Constitui um fator de risco que torna a pessoa vulnerável ao desenvolvimento de doença mental. Por sua vez, pessoas com experiência de doença mental, apresentam maior suscetibilidade para uma autoavaliação negativa. A abordagem holística do Modelo de Sistemas de Betty Neuman torna-o particularmente aplicável em pessoas que experimentam stressores complexos, que afetam múltiplas variáveis. Permite analisar como o cliente interage e dá resposta aos stressores, se adapta às mudanças, e aumenta a colaboração interdisciplinar. As intervenções de Enfermagem de Saúde Mental e Psiquiátrica com pessoas com baixa autoestima apresentam enfoque no autoconhecimento, na reestruturação cognitiva e na definição de objetivos de vida realistas, adequando o modo como a pessoa se valoriza e direcionando-a para ações construtivas. O desenho e a pintura foram utilizados, como mediadores expressivos, para representação de caraterísticas pessoais; do autoconceito e autoimagem; identificação de recursos pessoais e estratégias de coping utilizadas; reformulação de pensamentos; expressão de emoções e sentimentos; estimulação da criatividade; estimulação da interação social através de partilha ou discussão de uma opinião, agradecimento ou solicitação de ajuda. Com a realização das intervenções ao longo do estágio foi possível avaliar que estas facilitaram a tomada de consciência de si, a autoexploração e autodescoberta, a identificação de qualidades, estratégias de coping mais eficazes, a catarse, o estabelecimento de objetivos realistas para o futuro, e desenvolvimento de competências sociais, tornando-se assim evidente os contributos positivos destes mediadores expressivos.

Self-esteem corresponds to the perception and evaluation that each one makes of himself, interfering with all dimensions of personal experience. It is a dynamic, continuous and structured process since childhood, resulting from experiences that arise from the relationship with family, peers and society, subject to changes throughout life. With repercussions on affective and social life, well-being and quality of life, it corresponds to an indicator of mental health. It constitutes a risk factor that makes the person vulnerable to the development of mental illness. In turn, people with experience of mental illness are more susceptible to a negative self-assessment. The holistic approach of Betty Neuman's Model of Systems makes it particularly applicable to people who experience complex stressors that affect multiple variables. It allows analyzing how the client interacts and responds to stressors, adapts to changes, and increases interdisciplinary collaboration. Mental Health and Psychiatric Nursing interventions with people with low self esteem focus on self-knowledge, cognitive restructuring and the definition of realistic life goals, adapting the way the person values himself and directing him towards constructive actions. Drawing and painting were used as expressive mediators to represent personal characteristics; of self-concept and self-image; identification of personal resources and coping strategies used; reformulation of thoughts; expression of emotions and feelings; stimulation of creativity; stimulation of social interaction through sharing or discussing an opinion, thanking or asking for help. With the interventions carried out during the internship, it was possible to assess that they facilitated self-awareness, self-exploration and self-discovery, the identification of qualities, more effective coping strategies, catharsis, the establishment of realistic goals for the future, and development of social skills, thus making evident the positive contributions of these expressive mediators.

Intravesical Ty21a Treatment of Non-muscle-invasive Bladder Cancer Shows a Good Safety Profile.

Standard-of-care immunotherapy for non-muscle-invasive bladder cancer (NMIBC) with intravesical Bacillus Calmettte-Guérin (BCG) is associated with adverse events (AEs), disease recurrence/progression, and supply shortages. Preclinical data have shown that intravesical instillation of Ty21a/Vivotif, the oral vaccine against typhoid fever, may be an effective and safer alternative to BCG. We assessed the safety of intravesical Ty21a in NMIBC. For ethical reasons, patients with low- or intermediate-risk NMIBC not requiring BCG immunotherapy were enrolled. To determine the maximum tolerated dose, escalating doses of Ty21a/Vivotif were intravesically instilled in three patients once a week for 4 wk in phase 1a. In phase 1b, ten patients received the selected dose (1 × 108 CFU) once a week for 6 wk, as for standard BCG therapy. At this dose, all patients completed their treatment. Most patients experienced minor systemic AEs, while half reported mild local bladder AEs. AEs only occurred after one or two instillations for 40% of the patients. Ty21a bacteria were only recovered in three out of 72 urinary samples at 1 wk after instillation. Intravesical Ty21a might be well tolerated with no cumulative side effects, no fever >39 °C, and lower risk of bacterial persistence than with BCG. Ty21a treatment thus warrants clinical trials to explore its safety and antitumor efficacy in high-risk NMIBC. This trial is registered on ClinicalTrials.gov as NCT03421236. Patient summary: We examined the safety of a new intra-bladder immunotherapy for non-muscle-invasive bladder cancer as an alternative to the standard BCG treatment. Our data show that the Ty21a vaccine might be well tolerated. Further studies are needed to determine the safety and antitumor efficacy of this treatment.

Cost-Effective Fiber Optic Solutions for Biosensing.

In the last years, optical fiber sensors have proven to be a reliable and versatile biosensing tool. Optical fiber biosensors (OFBs) are analytical devices that use optical fibers as transducers, with the advantages of being easily coated and biofunctionalized, allowing the monitorization of all functionalization and detection in real-time, as well as being small in size and geometrically flexible, thus allowing device miniaturization and portability for point-of-care (POC) testing. Knowing the potential of such biosensing tools, this paper reviews the reported OFBs which are, at the moment, the most cost-effective. Different fiber configurations are highlighted, namely, end-face reflected, unclad, D- and U-shaped, tips, ball resonators, tapered, light-diffusing, and specialty fibers. Packaging techniques to enhance OFBs' application in the medical field, namely for implementing in subcutaneous, percutaneous, and endoscopic operations as well as in wearable structures, are presented and discussed. Interrogation approaches of OFBs using smartphones' hardware are a great way to obtain cost-effective sensing approaches. In this review paper, different architectures of such interrogation methods and their respective applications are presented. Finally, the application of OFBs in monitoring three crucial fields of human life and wellbeing are reported: detection of cancer biomarkers, detection of cardiovascular biomarkers, and environmental monitoring.

Children's Perspectives on Using Serious Games as a Complement to Promoting Their Social-Emotional Skills.

The use of serious games may be an appealing and complementary way to motivate curriculum-based social and emotional learning (SEL); still, investigation into this potential usefulness is scarce. This study aims to address the usefulness of serious games within the program 'Me and Us of Emotions'. Specifically, we analyzed the differences in children's satisfaction in sessions that did or did not use serious games as a complement to the intervention, explored the contribution of using serious games to the global satisfaction with the program, and explored children's qualitative feedback regarding the sessions. The participants were 232 children (122 boys and 110 girls) aged between 8 and 12 years old (M = 9.09, SD = 0.80). The measures were based on the subjective appraisals of the sessions made by the participating children, including quantitative and qualitative assessments of the degree of satisfaction of the participants. The results showed that there were similar levels of satisfaction with the sessions that did or did not use serious games as a complement to the program. However, only satisfaction with the sessions that used serious games (and not satisfaction with the sessions that did not use them) contributed significantly to explaining both the enjoyment of the activities and the interest in the subjects. Satisfaction with serious games was significantly and positively associated with fun, easiness, ability to understand the session, and ability to cope with emotions. Qualitative analysis showed three main themes, namely: positive aspects, negative aspects, and opportunities for improvement of the program. Overall, these results indicate that children's satisfaction with the 'Me and Us of Emotions' program is related to serious games, suggesting the relevance of using this complementary tool more often when intervening with younger generations.
