[Analysis of the challenges and dilemmas that bioethics of the 21st century will face in the digital health era]. / Análisis de retos y dilemas que deberá afrontar la bioética del siglo xxi, en la era de la salud digital.

The medical history underscores the significance of ethics in each advancement, with bioethics playing a pivotal role in addressing emerging ethical challenges in digital health (DH). This article examines the ethical dilemmas of innovations in DH, focusing on the healthcare system, professionals, and patients. Artificial Intelligence (AI) raises concerns such as confidentiality and algorithmic biases. Mobile applications (Apps) empower but pose challenges of access and digital literacy. Telemedicine (TM) democratizes and reduces healthcare costs but requires addressing the digital divide and interconsultation dilemmas; it necessitates high-quality standards with patient information protection and attention to equity in access. Wearables and the Internet of Things (IoT) transform healthcare but face ethical challenges like privacy and equity. 21st-century bioethics must be adaptable as DH tools demand constant review and consensus, necessitating health science faculties' preparedness for the forthcoming changes.

Results of a Community-Based Screening Program for Chlamydia trachomatis Genital Infection in Young People Aged 18-25 Years.

Introduction and aim Chlamydia trachomatis (CT) cases have increased in the last decade. The aim of the study was to assess the prevalence of CT genital infection in asymptomatic, sexually active young people and determine whether a community screening program would be effective in reducing the number of cases. Methods A descriptive cross-sectional studyof consecutive inclusion of asymptomatic people aged 18-25 years between September 2021 and May 2022. Community interventions in high schools, universities, and cultural events were planned to realize the screening. Sociodemographic variables of gender, age, country of origin, and educational level, as well as sexual habits, were recorded for each patient. CT was detected via urine samples. An estimate of the prevalence of CT genital infection and its 95% confidence interval (CI) was made based on the exact binomial distribution, assuming that the sample is representative of the study population. Results A total of 628 subjects participated in the study, of whom 33 had a CT infection, giving a prevalence of 5.2% (95% CI: 3.6%, 7.3%). 93.9% of subjects with CT infection were female (p≤0.019) and 85% of the participants were Spanish nationals. Among vocational training students, the prevalence was 8.1%. Having had four or more sexual partners in the last month and in the previous year was significantly associated with CT infection (p<0.001). Conclusion Screening for CT genital infection in young sexually active women should be implemented in our country, as recommended by the various guidelines.

Comparison of heart, grace and TIMI scores to predict major adverse cardiac events from chest pain in a Spanish health care region.

Acute non-traumatic chest pain (ANTCP) is the second cause of consultation in the Emergency department (ED). About 70% of all Acute Myocardial Infarctions present as non persistent ST-elevation acute coronary syndrome (NSTE-ACS) in the electrocardiogram. Our aim was to compare whether the HEART risk score is more effective than the GRACE and TIMI scores for the diagnosis and prognosis of Major Adverse Cardiac Events (MACE) at six weeks in patients with ANTCP and NSTE-ACS. A prospective cohort study was conducted with patients with ANTCP that attended an ED and a Primary Care Emergency Center (PCEC) from April 2018 to December 2020. The primary outcome was MACE at six weeks. Diagnostic performance was calculated for each scale as the Area under the Receiver Operating Characteristic (ROC) curve (AUC), sensitivity (SE), specificity (SP), and predictive values (PV). Qualitative variables were compared using the Chi-square test, and continuous variables were compared using the nonparametric Kruskal-Wallis test. We adjusted a logistic regression for risk groups, age, and gender to determine the effect of the HEART, GRACE, and TIMI scores on MACE. The degree of agreement (kappa index) was calculated in the categorical classification of patients according to the three risk scales. Cox proportional hazards regressions were performed for each scale and were compared using partial likelihood ratio tests for non-nested models. From a sample of 317 patients with ANTCP, 14.82% had MACE at six weeks. The AUC was 0.743 (95% CI 0.67-0.81) for the HEART score, 0.717 (95% CI 0.64-0.79) for the TIMI score, and 0.649 (95% CI 0.561-0.738) for the GRACE score. The HEART scale identified low-risk patients with a higher SE and negative PV than the GRACE and TIMI scores. The HEART scale was better than the GRACE and TIMI scores at diagnosing and predicting MACE at six weeks in patients with ANTCP and probable NSTE-ACS. It was also a reliable tool for risk stratification in low-risk patients. Its application is feasible in EDs and PCECs, avoiding the need for complementary tests and their associated costs without compromising patient health.

Improving Photodynamic Therapy Anticancer Activity of a Mitochondria-Targeted Coumarin Photosensitizer Using a Polyurethane-Polyurea Hybrid Nanocarrier.

Integration of photosensitizers (PSs) within nanoscale delivery systems offers great potential for overcoming some of the "Achiles' heels" of photodynamic therapy (PDT). Herein, we have encapsulated a mitochondria-targeted coumarin PS into amphoteric polyurethane-polyurea hybrid nanocapsules (NCs) with the aim of developing novel nanoPDT agents. The synthesis of coumarin-loaded NCs involved the nanoemulsification of a suitable prepolymer in the presence of a PS without needing external surfactants, and the resulting small nanoparticles showed improved photostability compared with the free compound. Nanoencapsulation reduced dark cytotoxicity of the coumarin PS and significantly improved in vitro photoactivity with red light toward cancer cells, which resulted in higher phototherapeutic indexes compared to free PS. Importantly, this nanoformulation impaired tumoral growth of clinically relevant three-dimensional multicellular tumor spheroids. Mitochondrial photodamage along with reactive oxygen species (ROS) photogeneration was found to trigger autophagy and apoptotic cell death of cancer cells.

A retrospective HEART risk score comparation of acute non-traumatic chest pain patients in an emergency department in Spain.

Non traumatic chest pain is the second most common cause of attention at the Emergency Departments (ED). The objective is to compare the effectiveness of HEART risk score and the risk of having a Major Adverse Cardiovascular Event (MACE) during the following 6 weeks in 'Acute Non-traumatic Chest Pain' (ANTCP) patients of an ED in Lleida (Spain). The ANTCP patient cohort was defined using medical data from January 2015 to January 2016. A retrospective study was performed among 300 ANTCP patients. Diagnostic accuracy to predict MACE, HEART risk score effectiveness and patient risk stratification were analysed on the ANTCP Cohort. HEART risk score was conducted on ANTCP Cohort data and patients were stratified as low-risk (n = 116, 38.7%), moderate-risk (n = 164, 54.7%) and high-risk (n = 20, 6.7%); differently from the assessment performed by 'Current Emergency Department Guidelines' (CEDG) on the same patients: low risk and discharge (n = 56, 18.7%), medium risk and need of complementary tests (n = 137, 45.7%) and high risk and hospital admission (n = 107, 35.7%).The incidence of MACE was 2.5%, 20.7% and 100% in low, moderate and high-risk, respectively. Discrimination and accuracy indexes were moderate (AUC = 0.73, 95% confidence interval: 0.67-0.80). Clustering moderate-high risk groups by MACE incidence showed an 89.5% of sensitivity. Data obtained from this study suggests that HEART risk score stratified better 'acute non-traumatic chest pain' (ANTCP) patients in an Emergency Department (ED) compared with 'Current Emergency Department Guidelines' (CEDG) at the Hospital Universitari Arnau de Vilanova (HUAV). HEART score would reduce the number of subsequent consultations, unnecessary admissions and complementary tests.Trial registration: Retrospectively registered.

Impact of the SARS-COV-2 Pandemic Lockdown on Sexually Transmitted Urethritis in a Spanish Health Region.

Background The incidence of sexually transmitted diseases (STD) has increased in recent years, especially in the young population. Urethritis is one of the most common clinical presentations of STD in emergency departments. During the SARS-COV-2 pandemic, in Spain lockdown lasted almost three months, and mobility was greatly restricted. This is the first study of these characteristics conducted in Spain. Methods A cross-sectional study of all patients treated for clinical symptoms of urethritis between March and June 2019 and between March and June 2020 was conducted. We evaluated patients' sociodemographic and clinical variables. Results Seventy-nine patients were included in the study: 37 in 2019 and 38 in 2020 of whom 94.9% were men. The main symptoms were urethral discharge (59.5%) followed by dysuria (26.6%). Risky sexual relations were reported by 63.2% of patients in 2019, and this percentage decreased to 43.9% in 2020. Conclusions The number of patients attending an emergency department in our health region for urethritis did not undergo any variations between 2019 and 2020. No significant reduction in the number of cases of urethritis was observed, probably because people continued with unsafe sexual relations despite the social restrictions and difficulties posed by the lockdown.

Survival Analysis of Geriatric Patients with Low Digestive Hemorrhage Attending an Emergency Department.

BACKGROUND: The increase in life expectancy and low mortality have doubled the number of individuals older than 65 in the last 30 years. METHODS: We conducted a retrospective study of 101 patients older than 80 years of age treated by low digestive hemorrhage (LDH) in an emergency department during 2018. Sociodemographic variables were evaluated, as well as comorbidity and survival at 18 months. Survival was assessed by a Kaplan-Meier test. RESULTS: 52.5% of the subjects were women. The average comorbidity of the sample was 1.97. The survival rate per year was 60%. The finding on colonoscopy shows no association with mortality. However, those patients on anticoagulant/antiplatelet therapy have a higher survival rate. CONCLUSION: Survival per year is high, so urgent colonoscopy for an LDH should be performed after evaluating the patient's stability and functional status in a scheduled and outpatient manner.

Palliative sedation and mortality in emergency departments: descriptive study of cases in the MORCAT registry. / Registro MORCAT: descripción de la sedación paliativa y la mortalidad en los servicios de urgencias.

OBJECTIVES: To describe the clinical management of palliative sedation and the characteristics of sedated patients in 11 Catalan hospital emergency departments. MATERIAL AND METHODS: Prospective descriptive study of a cohort of patients given palliative sedation between April and July 2018. We registered patient demographic and disease data, the Charlson comorbidity index (CCI), patient's point of origin before emergency department arrival, times related to emergency care, and medications used. RESULTS: We included 323 patients (48.9% men) with a mean (SD) age of 84 (12) years. The CCIs were significantly higher in patients attended in level-I hospitals. Palliative sedation was the first option in 27% and was initiated within 18 (28) hours of arrival on average, an interval that was significantly shorter in level-II hospitals. Most patients (74.2%) died in the emergency department. CONCLUSION: Patients treated with palliative sedation in hospital emergency departments are older and have serious concomitant conditions. Most patients are first treated with intention to cure. Time until the start of palliative sedation differs significantly according to hospital level.

OBJETIVO: Describir las características y manejo de los pacientes con sedación paliativa (SP) en 11 servicios de urgencias hospitalarios (SUH) catalanes. METODO: Estudio prospectivo descriptivo de pacientes que recibieron SP entre abril y julio de 2018. Se recogieron variables demográficas, enfermedades del paciente, índice de Charlson (IC), procedencia, tiempos en urgencias y fármacos utilizados. RESULTADOS: Se incluyeron 323 pacientes (48,9% varones) con una edad media de 84 (DE 12) años. El IC fue significativamente mayor en hospitales de primer nivel. La SP se consideró primera opción de tratamiento en el 27% y se inició en una media de 18 (DE 28) horas tras su llegada, significativamente diferente en hospitales de segundo nivel. Fallecieron mayoritariamente en el SUH (74,2%). CONCLUSIONES: Los pacientes que reciben SP en los SUH son ancianos con comorbilidad grave, y en su mayoría reciben tratamiento con intención curativa como primera opción terapéutica. Existen diferencias significativas del tiempo transcurrido hasta el inicio de la SP según la complejidad del centro.

Exacerbations of chronic obstructive pulmonary disease: An analysis of the care process in a regional hospital emergency department.

To describe the characteristics of patients visiting a Hospital Emergency Department (HED) due to chronic obstructive pulmonary disease (COPD) exacerbation (AECOPD) and to evaluate their management.A cross-sectional study of the first 219 patients with AECOPD visiting the HED of the University Hospital Arnau de Vilanova, Lleida, Spain, was performed from January to May 2016. The data collected included the following: main patient characteristics, diagnostic tests, applied treatments, response times, discharge destination, need for hospital admission, and re-admissions and deaths at 90 days. Comparisons were made according to sex and need for hospitalization.The patients consisted of 84% men, with a mean age (standard deviation [SD]) of 75.9 (11) years and a FEV1/FVC of 56 (13)%; 63% were ex-smokers. The median time (P25-P75) in the HED was 6 (4-10) hours, with shorter waiting times for severe patients. Additionally, 74% of patients required hospital admission. The percentages of re-admissions and mortality at 90 days were 25% and 14%, respectively. Among female patients, 63% never consumed tobacco, and the most frequent clinical phenotype was asthma combined with COPD; female patients visited the family doctor sooner after AECOPD than men (4 vs 7 days). Overall, the following areas of improvement were identified: use of sputum culture (performed in 3% of patients); documentation of variables; patient care times; and reduction in the time until first medical check-up.The overall quality of care provided to AECOPD patients was satisfactory and consistent with current clinical guidelines. Nevertheless, improving the quality of care at the HED requires establishing protocols that ensure that the necessary diagnostic tests are performed, optimize response times and guarantee that all relevant information is collected.

Assessment of the length of sick leave in patients with ischemic heart disease.

BACKGROUND: The prevalence of ischemic heart disease is high. Few recent studies have investigated the periods of sick leave of these patients. Our aim is to determine the length of sick leave after an acute coronary syndrome, its costs, associated factors and to assess the use of antidepressants and/or anxiolytics. METHODS: An observational study of a retrospective cohort of patients on sick leave due to ischemic heart disease in a health region between 2008-2011, with follow-up until the first return to work, death, or end of the study (31/12/2012). MEASUREMENTS: length of sick leave, sociodemographic variables and medical prescriptions. RESULTS: Four hundred and ninety-seven patients (mean age 53 years, 90.7% male), diagnosed with acute myocardial infarction (60%), angina pectoris (20.7%) or chronic form of ischemic heart disease (19.1%). Thirty-seven per cent of patients took anxiolytics the year after diagnosis and 15% took antidepressants. The average duration of sick leave was 177 days (95% CI: 163-191 days). Patients diagnosed with acute myocardial infarction returned to work after a mean of 192 days, compared to 128 days in cases with angina pectoris. Patients who took antidepressants during the year after diagnosis returned to work after a mean of 240 days. The mean work productivity loss was estimated to be 9,673 euros/person. CONCLUSIONS: The mean duration of sick leave due to ischemic heart disease was almost six months. Consumption of psychotropic medication doubled after the event. Older age, suffering an acute myocardial infarction and taking antidepressants were associated with a longer sick leave period.

Association between Sick Leave Prescribing Practices and Physician Burnout and Empathy.

OBJECTIVES: To investigate the association between sick leave prescription and physician burnout and empathy in a primary care health district in Lleida, Spain. METHODS: This descriptive study included 108 primary care doctors from 22 primary care centers in Lleida in 2014 (183,600 patients). Burnout was measured with the Maslach Burnout Inventory and empathy with the Jefferson Scale of Physician Empathy. The reliability of the instruments was measured by calculating Cronbach's alpha and normal distribution was analyzed using the Kolmogorov-Smirnov-Lilliefors and χ2 tests. Burnout and empathy scores were analyzed by age, sex, and place of work (urban vs rural). Sick leave data were obtained from the Catalan Health Institute. RESULTS: High empathy was significantly associated with low burnout. Neither empathy nor burnout were significantly associated with sick leave prescription. CONCLUSION: Sick leave prescription by physicians is not associated with physicians' empathy or burnout and may mostly depend on prescribing guidelines.

Hardware optimization and serial implementation of a novel spiking neuron model for the POEtic tissue.

In this paper we describe the hardware implementation of a spiking neuron model, which uses a spike time dependent plasticity (STDP) rule that allows synaptic changes by discrete time steps. For this purpose an integrate-and-fire neuron is used with recurrent local connections. The connectivity of this model has been set to 24 neighbours, so there is a high degree of parallelism. After obtaining good results with the hardware implementation of the model, we proceed to simplify this hardware description, trying to keep the same behaviour. Some experiments using dynamic grading patterns have been used in order to test the learning capabilities of the model. Finally, the serial implementation has been realized.
