RESUMEN
The targeted pollination strategy has shown positive results in directing honey bees to crop flowers offering nectar along with pollen as reward. Kiwifruit is a functionally dioecious species, which relies on bees to transport pollen from staminate to pistillate nectarless flowers. Following the targeted pollination procedures recently validated, we first developed a mimic odor (KM) based on kiwifruit floral volatiles for which bees showed the highest level of generalization to the natural floral scent, although the response towards pistillate flowers was higher than towards staminate flowers. Then, in the field, feeding colonies KM-scented sucrose solution resulted in higher amounts of kiwifruit pollen collected by honey bees compared to control colonies fed unscented sucrose solution. Our results support the hypothesis that olfactory conditioning bees biases their foraging preferences in a nectarless crop, given the higher visitation to target flowers despite having provided the mimic odor paired with a sugar reward.

Many local agencies in the United States and other countries are tasked to install air pollution monitoring systems of highly accurate sensors that have high acquisition, operating, and maintenance costs. The need for expanded coverage of air quality measurements across Salt Lake County (SLCO), Utah is being met by mounting air quality and temperature sensors on an expanding fleet of battery electric buses (BEBs). Monitoring air quality from a mobile sensor network provides real-time insights into air pollution patterns at high temporal and spatial resolution. Mobile measurements contribute to assessing residents' exposure to air pollution, facilitating the implementation of cost-effective public health policies and highlighting disparities. The Electric Bus Air Quality Observation Project was launched in SLCO during July 2021 and has collected millions of observations to date. A BEB traveling at typical traffic speeds (~10â¯mâ¯s-1) can provide multiple measurements along city block lengths of up to ~200â¯m. With careful analysis that factors in the time response of the differing sensors, variability from block-to-block may be attributed to fine-scale factors (e.g., pollution and heat sources, tree shading and urban vegetation, etc.). Preliminary findings showcase the value of increased coverage and resolution. During an extreme heat event in July 2023, both the morning and afternoon temperature readings showed differences of over 6.5⯰C (12⯰F), primarily as an east-west gradient with similar gradients in ozone. We conclude that temperature and pollutant concentration readings, at fine spatial and temporal resolutions, will facilitate future health studies and equitable policy and mitigation strategies. Our study demonstrates that our partnerships established with governmental, non-profit, and transit agencies facilitate the successful transfer of research and development to operational real-time mobile air quality monitoring.
RESUMEN
Intraventricular neurocytoma is a low incidence central nervous system tumor. It predominantly affects young adults with no apparent gender predilection. The main symptoms include headache, nausea and vomiting. These result from hydrocephalus due to the obstruction of cerebrospinal fluid flow. On diagnostic imaging, neurocytoma can be suspected by some features, such as peripheral cysts, lobulated contours and septa that bridge the ventricular wall, giving a "scalloped" appearance. There are other characteristics, but they are less specific for the diagnosis. The atypical variant of neurocytoma is even rarer and leads to a worst prognosis. Atypical neurocytomas develop higher proliferative potential identified by the Ki-67 biomarker and higher recurrence rate. There are few studies about the imaging characteristics of atypical neurocytomas. At this point, there are no reliable distinctive features to differentiate atypical neurocytomas, especially due to their low incidence. We present the case of a 20-year-old female patient with symptoms of intracraneal hypertension. CT and MRI of the brain revealed a mass occupying the body of the left lateral ventricle, adjacent to the foramen of Monro. The mass was primarily solid with discrete peripheral cyst and a few scalloped areas. It also showed signs of supratentorial obstructive hydrocephalus. The tumor was partially removed because of bleeding and compromise of vascular structures. Immunohistochemistry revealed positive synaptophysin, elevated Ki-67 (7%), increased number of blood vessels and moderate nuclear atypia. After surgery, the patient persisted with signs of intracranial hypertension, not improving with clinical management and requiring aggressive surgical procedures. While rare, atypical neurocytoma requires a better characterization, especially through imaging, to optimize immediate management and explore new therapeutic options.
RESUMEN
BACKGROUND: The COVID-19 pandemic accelerated the use of telehealth. However, this also exacerbated healthcare disparities for vulnerable populations. OBJECTIVE: To explore the feasibility and effectiveness of a medical student-led initiative to identify and address gaps in patient access to digital health resources in adult primary care clinics at a safety-net academic center. METHODS: Medical students used an online HIPAA-compliant resource directory to screen for digital needs, connect patients with resources, and track outcome metrics. Through a series of Plan-Do-Study-Act (PDSA) cycles, the program grew to offer services such as information and registration for subsidized internet and phone services via the Affordable Connectivity Program (ACP) and Lifeline, assistance setting up and utilizing MyChart (an online patient portal for access to electronic health records), orientation to telehealth applications, and connection to community-based digital literacy training. RESULTS: Between November 2021 and March 2023, the program received 608 assistance requests. The most successful intervention was MyChart help, resulting in 83% of those seeking assistance successfully signing up for MyChart accounts and 79% feeling comfortable navigating the portal. However, subsidized internet support, digital literacy training, and telehealth orientation had less favorable outcomes. The PDSA cycles highlighted numerous challenges such as inadequate patient outreach, time-consuming training, limited in-person support, and unequal language assistance. To overcome these barriers, the program evolved to utilize clinic space for outreach, increase flier distribution, standardize training, and enhance integration of multilingual resources. CONCLUSION: This study is, to the best of our knowledge, the first time a medical student-led initiative addresses the digital divide with a multi-pronged approach. We outline a system that can be implemented in other outpatient settings to increase patients' digital literacy and promote health equity, while also engaging students in important aspects of non-clinical patient care.
RESUMEN
Adolescents and young adults (AYAs) living with HIV have high rates of co-sexually transmitted infections (STIs). During the coronavirus disease (COVID) pandemic, STI prevention strategies, including access to testing/treatment facilities, availability of health care workers, and condom availability, may have decreased. This study aimed to determine if differences in STI incidence for first infection and reinfection existed between the pre-COVID and COVID eras in a cohort of AYAs living with HIV in Atlanta, GA. Retrospective chart review was conducted for all patients between ages 13 and 24 at the Grady Ponce Clinic. Two eras were identified: a pre-COVID era (January 1, 2009-December31, 2019) and a COVID era (January 1, 2020-June 30, 2021). STIs recorded included gonorrhea, chlamydia, human papillomavirus, syphilis, trichomonas, herpes simplex virus, lymphogranuloma venereum, hepatitis C, bacterial vaginosis, and chancroid. First and recurrent incidence rates for any STIs were reported. Our sample included 766 sexually active AYAs with HIV. A total of 721 patients were included in the pre-COVID era and 583 (80.9%) had at least one STI. A total of 337 patients were included in the COVID era, and 158 had at least one STI (46.9%). The overall first STI incidence rate increased from 42.47 to 58.67 per 100 person-years (PY) and the recurrent STI incidence rate increased from 121.50 to 169.85 per 100 PY from the pre-COVID to the COVID era (p < 0.001). Our study demonstrated significantly higher incidence rates of first and recurrent STIs in AYAs living with HIV in the COVID era. We urge continuation of existing STI prevention programs to avoid secondary clinical and economic adverse effects of increased infections.

Objective: Cleft lip and palate is the most common craniofacial birth anomaly and requires surgery in the first year of life. However, craniofacial surgery training opportunities are limited. The aim of this study was to present and evaluate an open-source cleft lip and palate hybrid (casting and three-dimensional (3D) printing) simulation model which can be replicated at low cost to facilitate the teaching and training of cleft surgery anatomy and techniques. Design: The soft tissue component of the cleft surgery training model was casted using a 3D printed 5-component mold and silicone. The bony structure was designed to simulate the facial anatomy and to hold the silicone soft tissue. Setting: Two groups, one group of trainees and one group of expert surgeons, at University Hospital Basel in Switzerland and Pontifical Catholic University of Chile in Santiago, Chile, tested the cleft lip and palate simulation model. Participants completed a Likert-based face and content validity questionnaire to assess the realism of the model and its usefulness in surgical training. Results: More than 70 % of the participants agreed that the model accurately simulated human tissues found in patients with unilateral cleft lip and palate. Over 60 % of the participants also agreed that the model realistically replicated surgical procedures. In addition, 80-90 % of the participants found the model to be a useful and appropriate tool for teaching the anatomy and surgical techniques involved in performing unilateral cleft lip and palate repair. Conclusion: This open-source protocol provides a cost-effective solution for surgeons to introduce the cleft morphology and surgical techniques to trainees on a regular basis. It addresses the current financial barrier that limits access to commercially available models during the early stages of surgeon training prior to specialization in the field.
RESUMEN
OBJECTIVES: Determine SARS-CoV-2 IgG antibody incidence over time in unvaccinated pediatric healthcare workers (pHCWs). DESIGN: A prospective longitudinal cohort of unvaccinated pHCWs measuring the incidence of new infection after initial prevalence was established at 4.1% with seropositive predominance in emergency department (ED)-based pHCWs. Serum samples were collected at follow-up visits to detect new SARS-CoV-2 seropositivity. Univariate analysis was performed to estimate different incidence rates between participant demographics, job, employment location, and community risk factors. Anxiety levels about COVID-19 were collected. SARS-CoV-2 antibody decay postinfection and neutralization antibodies were evaluated. Log-linear Poisson regression models were used to estimate incidence. RESULTS: Of 642 initially enrolled, 390 pHCWs presented for at least one follow-up serology test after baseline analysis. The incidence of SARS-CoV-2 seropositivity was 8.2%. The seropositive cohort, like the negative one, consisted mainly of females in non-ED settings and nonphysician roles. There were no statistically significant differences in incidence across variables. Seropositive participants dropped antibody titers by 50% at 3 months. Neutralization antibodies correlated to SARS-CoV-2 binding antibodies (r = 0.43, P < 0.0001). CONCLUSION: The incidence of seropositivity was 8.2%. Although seropositivity was higher among ED staff during the early stages of the pandemic, this difference declined over time, likely due to the universal adoption of personal protective equipment.

BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) recommends an upper limit of 10% for atypia of undetermined significance (AUS). Recent data suggest that this category might be overused when the rate of cases with molecular positive results is low. As a quality metric, the AUS and positive call rates for this facility's cytology laboratory and each cytopathologist (CP) were calculated. METHODS: A retrospective analysis of all thyroid cytology cases in a 4.5-year period was performed. Cases were stratified by TBSRTC, and molecular testing results were collected for indeterminate categories. The AUS rate was calculated for each CP and the laboratory. The molecular positive call rate (PCR) was calculated with and without the addition of currently negative to the positive results obtained from the ThyroSeq report. RESULTS: A total of 7535 cases were classified as nondiagnostic, 7.6%; benign, 69%; AUS, 17.5%; follicular neoplasm/suspicious for follicular neoplasm, 1.4%; suspicious for malignancy, 0.7%; and malignant, 3.8%. The AUS rate for each CP ranged from 9.9% to 36.8%. The overall PCR was 24% (range, 13%-35.6% per CP). When including cases with currently negative results, the PCR increased to 35.5% for the cytology laboratory (range, 13%-42.6% per CP). Comparison analysis indicates a combination of overcalling benign cases and, less frequently, undercalling of higher TBSRTC category cases. CONCLUSIONS: The AUS rate in the context of PCR is a useful metric to assess cytology laboratory and cytopathologists' performance. Continuous feedback on this metric could help improve the overall quality of reporting thyroid cytology.

Introduction Uncontrolled hypertension significantly contributes to the development and deterioration of various medical conditions, such as myocardial infarction, chronic kidney disease, and cerebrovascular events. Despite being the most common preventable risk factor for all-cause mortality, only a fraction of affected individuals maintain their blood pressure in the desired range. In recent times, there has been a growing reliance on online platforms for medical information. While providing a convenient source of information, differentiating reliable from unreliable information can be daunting for the layperson, and false information can potentially hinder timely diagnosis and management of medical conditions. The surge in accessibility of generative artificial intelligence (GeAI) technology has led to increased use in obtaining health-related information. This has sparked debates among healthcare providers about the potential for misuse and misinformation while recognizing the role of GeAI in improving health literacy. This study aims to investigate the accuracy of AI-generated information specifically related to hypertension. Additionally, it seeks to explore the reproducibility of information provided by GeAI. Method A nonhuman-subject qualitative study was devised to evaluate the accuracy of information provided by ChatGPT regarding hypertension and its secondary complications. Frequently asked questions on hypertension were compiled by three study staff, internal medicine residents at an ACGME-accredited program, and then reviewed by a physician experienced in treating hypertension, resulting in a final set of 100 questions. Each question was posed to ChatGPT three times, once by each study staff, and the majority response was then assessed against the recommended guidelines. A board-certified internal medicine physician with over eight years of experience further reviewed the responses and categorized them into two classes based on their clinical appropriateness: appropriate (in line with clinical recommendations) and inappropriate (containing errors). Descriptive statistical analysis was employed to assess ChatGPT responses for accuracy and reproducibility. Result Initially, a pool of 130 questions was gathered, of which a final set of 100 questions was selected for the purpose of this study. When assessed against acceptable standard responses, ChatGPT responses were found to be appropriate in 92.5% of cases and inappropriate in 7.5%. Furthermore, ChatGPT had a reproducibility score of 93%, meaning that it could consistently reproduce answers that conveyed similar meanings across multiple runs. Conclusion ChatGPT showcased commendable accuracy in addressing commonly asked questions about hypertension. These results underscore the potential of GeAI in providing valuable information to patients. However, continued research and refinement are essential to evaluate further the reliability and broader applicability of ChatGPT within the medical field.
RESUMEN
Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory condition of the nasal and paranasal tissues, characterized by the presence of bilateral nasal polyps. While etiology and pathogenetic mechanisms are heterogeneous and complex, in most patients, disease is mediated predominantly through type 2 inflammatory processes. Clinical management is challenging, and a multidisciplinary approach is preferred. Principal treatment approaches are the use of local/systemic corticosteroids and sinonasal surgery, although outcomes can be unsatisfactory. Recent availability of biological therapies targeting underlying inflammatory processes can offer effective treatment options in uncontrolled disease. Specialist guidelines greatly assist clinical decision-making, although as these are chiefly written from a global/international perspective, they may not wholly accommodate disease patterns and clinical practice at a regional level. An expert panel of specialists from Latin America was convened to develop regional guidance on the management of CRSwNP through a consensus approach. The present article presents the chief observations and recommendations which can provide guidance for clinicians in the Latin American region.
RESUMEN
BACKGROUND: Combined intramuscular long-acting cabotegravir and long-acting rilpivirine constitute the first long-acting combination antiretroviral therapy (ART) regimen approved for adults with HIV. The goal of the IMPAACT 2017 study (MOCHA [More Options for Children and Adolescents]) was to assess the safety and pharmacokinetics of these drugs in adolescents. METHODS: In this phase 1/2, multicentre, open-label, non-comparative, dose-finding study, virologically suppressed adolescents (aged 12-17 years; weight ≥35 kg; BMI ≤31·5 kg/m2) with HIV-1 on daily oral ART were enrolled at 15 centres in four countries (Botswana, South Africa, Thailand, and the USA). After 4-6 weeks of oral cabotegravir (cohort 1C) or rilpivirine (cohort 1R), participants received intramuscular long-acting cabotegravir or long-acting rilpivirine every 4 weeks or 8 weeks per the adult dosing regimens, while continuing pre-study ART. The primary outcomes were assessments of safety measures, including all adverse events, until week 4 for oral cabotegravir and until week 16 for long-acting cabotegravir and long-acting rilpivirine, and pharmacokinetic measures, including the area under the plasma concentration versus time curve during the dosing interval (AUC0-tau) and drug concentrations, at week 2 for oral dosing of cabotegravir and at week 16 for intramuscular dosing of cabotegravir and rilpivirine. Enrolment into cohort 1C or cohort 1R was based on the participant's pre-study ART, meaning that masking was not done. For pharmacokinetic analyses, blood samples were drawn at weeks 2-4 after oral dosing and weeks 4-16 after intramuscular dosing. Safety outcome measures were summarised using frequencies, percentages, and exact 95% CIs; pharmacokinetic parameters were summarised using descriptive statistics. This trial is registered at ClinicalTrials.gov, NCT03497676, and is closed to enrolment. FINDINGS: Between March 19, 2019, and Nov 25, 2021, 55 participants were enrolled: 30 in cohort 1C and 25 in cohort 1R. At week 16, 28 (97%, 95% CI 82-100) of the 29 dose-evaluable participants in cohort 1C and 21 (91%; 72-99) of the 23 dose-evaluable participants in cohort 1R had reported at least one adverse event, with the most common being injection-site pain (nine [31%] in cohort 1C; nine [39%] in cohort 1R; none were severe). One (4%, 95% CI 0-22) participant in cohort 1R had an adverse event of grade 3 or higher, leading to treatment discontinuation, which was defined as acute rilpivirine-related allergic reaction (self-limiting generalised urticaria) after the first oral dose. No deaths or life-threatening events occurred. In cohort 1C, the week 2 median cabotegravir AUC0-tau was 148·5 (range 37·2-433·1) µg·h/mL. The week 16 median concentrations for the every-4-weeks and every-8-weeks dosing was 3·11 µg/mL (range 1·22-6·19) and 1·15 µg/mL (<0·025-5·29) for cabotegravir and 52·9 ng/mL (31·9-148·0) and 39·1 ng/mL (27·2-81·3) for rilpivirine, respectively. These concentrations were similar to those in adults. INTERPRETATION: Study data support using long-acting cabotegravir or long-acting rilpivirine, given every 4 weeks or 8 weeks, per the adult dosing regimens, in virologically suppressed adolescents aged 12 years and older and weighing at least 35 kg.

BACKGROUND: Long-acting injectable cabotegravir and rilpivirine have demonstrated safety, acceptability, and efficacy in adults living with HIV-1. The IMPAACT 2017 study (MOCHA study) was the first to use these injectable formulations in adolescents (aged 12-17 years) living with HIV-1. Herein, we report acceptability and tolerability outcomes in cohort 1 of the study. METHODS: In this a secondary analysis of a phase 1/2, multicentre, open-label, non-comparative dose-finding study, with continuation of pre-study oral combination antiretroviral treatment (ART), 55 adolescents living with HIV-1 were enrolled to receive sequential doses of either long-acting cabotegravir or rilpivirine and 52 received at least two injections. Participants had a body weight greater than 35 kg and BMI less than 31·5 kg/m2 and had been on stable ART for at least 90 consecutive days with an HIV-1 viral load of less than 50 copies per mL at a participating IMPAACT study site. Participants had to be willing to continue their pre-study ART during cohort 1. The primary objectives of the study were to confirm doses for oral and injectable cabotegravir and for injectable rilpivirine in adolescents living with HIV. This analysis of participant-reported outcomes included a face scale assessment of pain at each injection and a Pediatric Quality of Life Inventory (PedsQL) at baseline and week 16 for participants in the USA, South Africa, Botswana, and Thailand. A subset of 11 adolescents and 11 parents or caregivers in the USA underwent in-depth interviews after receipt of one or two injections. This trial is registered at ClinicalTrials.gov, NCT03497676. FINDINGS: Between March 19, 2019, and Nov 25, 2021, 55 participants were enrolled into cohort 1. Using the six-point face scale, 43 (83%) of participants at week 4 and 38 (73%) at week 8 reported that the injection caused "no hurt" or "hurts little bit", while only a single (2%) participant for each week rated the pain as one of the two highest pain levels. Quality of life was not diminished by the addition of one injectable antiretroviral. In-depth interviews revealed that parents and caregivers in the USA frequently had more hesitancy than adolescents about use of long-acting formulations, but parental acceptance was higher after their children received injections. INTERPRETATION: High acceptability and tolerability of long-acting cabotegravir or rilpivirine injections suggests that these are likely to be favoured treatment options for some adolescents living with HIV.

When training Artificial Intelligence and Deep Learning models, especially by using Supervised Learning techniques, a labeled dataset is required to have an input with data and its corresponding labeled output data. In the case of images, for classification, segmentation, or other processing tasks, a pair of images is required in the same sense, one image as an input (the noisy image) and the desired (the denoised image) one as an output. For SAR despeckling applications, the common approach is to have a set of optical images that then are corrupted with synthetic noise, since there is no ground truth available. The corrupted image is considered the input and the optical one is the noiseless one (ground truth). In this paper, we provide a dataset based on actual SAR images. The ground truth was obtained from SAR images of Sentinel 1 of the same region in different instants of time and then they were processed and merged into one single image that serves as the output of the dataset. Every SAR image (noisy and ground truth) was split into 1600 images of 512 × 512 pixels, so a total of 3200 images were obtained. The dataset was also split into 3000 for training and 200 for validation, all of them available in four labeled folders.
RESUMEN
Having reliable interdependent infrastructure networks is vital for well-being of a safe and productive society. Systems are vulnerable to failure or performance loss due to their interdependence among various networks, as each failure can propagate through the whole system. Although the conventional view has concentrated on optimizing the restoration of critical interdependent infrastructure networks using a centralized approach, having a lone actor as a decision-maker in the system is substantially different from the actual restoration decision environment, wherein infrastructure utilities make their own decisions about how to restore their network service. In a decentralized environment, the definition of whole system optimality does not apply as each decision-maker's interest may not converge with the others. Subsequently, this results in each decision-maker developing its own reward functions. Therefore, in this study, we address the concern of having multiple decision-makers with various payoff functions in interdependent networks by proposing a decentralized game theory algorithm for finding Nash equilibria solutions for network restoration in postdisaster situations.
RESUMEN
Today, type 2 diabetes mellitus (T2DM) and skeletal muscle atrophy (SMA) have become increasingly common occurrences. Whether the onset of T2DM increases the risk of SMA or vice versa has long been under investigation. Both conditions are associated with negative changes in skeletal muscle health, which can, in turn, lead to impaired physical function, a lowered quality of life, and an increased risk of mortality. Poor nutrition can exacerbate both T2DM and SMA. T2DM and SMA are linked by a vicious cycle of events that reinforce and worsen each other. Muscle insulin resistance appears to be the pathophysiological link between T2DM and SMA. To explore this association, our review (i) compiles evidence on the clinical association between T2DM and SMA, (ii) reviews mechanisms underlying biochemical changes in the muscles of people with or at risk of T2DM and SMA, and (iii) examines how nutritional therapy and increased physical activity as muscle-targeted treatments benefit this population. Based on the evidence, we conclude that effective treatment of patients with T2DM-SMA depends on the restoration and maintenance of muscle mass. We thus propose that regular intake of key functional nutrients, along with guidance for physical activity, can help maintain euglycemia and improve muscle status in all patients with T2DM and SMA.

RESUMEN
This study aims to review surgical treatment in paediatric condylar fractures and describe different types of techniques performed, along with the results obtained from them. A retrospective review was conducted from records of paediatric patients (from one to 17 years old) who sustained fractures of the mandibular condyle and underwent surgical treatment from 2003 to 2023. The number of patients, age, location, and type of fracture, clinical and imaging examinations, treatment methods, intraoperative/postoperative complications, removal of osteosynthesis material, follow up and outcomes were recorded and analysed. A total of 68 patients with 79 fractures were identified. The most common fracture pattern was condylar neck fracture (61.1%). Of the 68 patients who underwent surgical treatment, one had a complication of minimal temporal paraesthesia and another patient had near-complete resorption of the condyle. A total of 55 patients (81%) reported normal dental occlusion, mouth opening (>35 mm), lateral excursions (7-8 mm), TMJ function, no pain, no deviation of the midline or the jaw, and no ankylosis. Thirteen patients (19%) developed an unsatisfactory result, nine patients (13%) had a jaw deviation on mouth opening, four patients (6%) had mandibular retrusion, and seven patients (10%) had signs of TMJ dysfunction. A total of 59 patients (87%) reported bone completely healed with no signs of bone abnormality; seven patients (10%) had shortening of the condylar neck and/or ramus. Surgical treatment can lead to good or excellent results for severely dislocated and displaced condylar fractures in children and can reduce the unsatisfactory results resulting from closed treatment.

Resumo A legalidade da morte assistida é controversa em todo o mundo devido a aspectos bioéticos. Em países como Luxemburgo e Canadá, a eutanásia foi aprovada, gerando impactos positivos na qualidade de vida de pacientes; entretanto, há aspectos negativos, como o abandono de opções paliativas. Esta revisão bibliográfica descritiva considerou publicações dos últimos cinco anos com enfoques bioéticos a favor da morte assistida, com base na importância de aliviar definitivamente a sintomatologia do paciente, além de proporcionar qualidade de vida, mas referiu também que a longo prazo a legalidade desse procedimento pode acarretar desumanização médica. O Código Orgânico Integral Penal Integral do Equador apresenta artigos ambíguos a favor e contra a morte assistida, com brechas legais que não permitem sua aplicação no sistema de saúde. Embora haja argumentos sólidos a favor e contra a eutanásia, a decisão deve ser adaptada ao contexto do paciente e do sistema de saúde.
Abstract The legality of assisted dying is a controversial matter worldwide due to bioethical aspects. In countries such as Luxembourg and Canada, euthanasia was approved, with positive impacts on the quality of life of patients; however, there are negative aspects, such as not taking palliative options into consideration. This descriptive literature review considered publications from the last five years with bioethical approaches in favor of assisted dying, based on the importance of definitively alleviating patient symptomatology, in addition to providing quality of life, but also noting that in the long term the legality of this procedure may lead to medical dehumanization. Ecuador's Comprehensive Organic Criminal Code presents ambiguous articles for and against assisted dying, with legal loopholes that preclude its application in the health care system. Despite solid arguments for and against euthanasia, the decision must be adapted to the context of the patient and health care system.

Objective: To identify the effect of workplace health promotion activities (WHPA) on the health status of health personnel. Methodology: A systematic literature review was performed. Six computerized databases were used to search for studies on the effect of at least one health promotion activity on the health status of health personnel. Studies were included if they were published in peer-reviewed and indexed journals and were written either in English, Spanish, or Portuguese. Information such as study population, sample size, type of study, outcome, and health promotion activities performed were extracted from each publication. All the included articles were measured in terms of their methodological quality, including the risk of bias. Results: Lower scores on perceived stress, emotional exhaustion, and mood symptoms were reported. An improvement in sleep hours and quality and a reduction in dietary sodium intake were informed. Improvements in participants' dietary habits, weight loss, and body fat percentage, along with increased physical activity and a reduction in pain levels were reported. A reduction in the prevalence of cigarette smoking was found. Conclusions: WHPAs can enhance physical and mental health, and overall well-being, and encouraging healthier behaviors among health personnel. Most of the studies targeting mental health focused their efforts primarily on reducing healthcare workers' perceived stress. WHPAs that addressed both diet and physical activity behaviors were more effective at improving weight outcomes than those that used only one approximation. Overall, this study offers valuable information on the impact of worksite-based health promotion interventions, including the effect of different strategies applied.
Objetivo: Identificar el efecto de las actividades de promoción de la salud en el lugar de trabajo (APST) sobre el estado de salud del personal sanitario. Metodología: Se realizó una revisión sistemática de la literatura. Se utilizaron seis bases de datos computarizadas para buscar estudios sobre el efecto de al menos una actividad de promoción de la salud en el estado de salud del personal sanitario. Se incluyeron los estudios publicados en revistas revisadas por pares e indexadas y escritos en inglés, español o portugués. De cada publicación se extrajo información como la población del estudio, el tamaño de la muestra, el tipo de estudio, el resultado y las actividades de promoción de la salud realizadas. Se analizaron todos los artículos incluidos en términos de su calidad metodológica, teniendo en cuenta el riesgo de sesgo. Resultados: Se registraron puntuaciones menos elevadas en el estrés percibido, agotamiento emocional y alteración del estado de ánimo. Se informó de una mejoría en las horas y la calidad del sueño, y de una reducción de la ingesta de sodio en la dieta. Se registraron mejorías en los hábitos alimentarios de los participantes, pérdida de peso y porcentaje de grasa corporal, así como un aumento de la actividad física y una reducción de los niveles de dolor. Se observó una reducción de la prevalencia del tabaquismo. Conclusiones: Las AMPS pueden mejorar la salud física y mental, así como el bienestar general, y fomentar comportamientos más saludables entre el personal sanitario. La mayoría de los estudios dirigidos a la salud mental centraron sus esfuerzos principalmente en reducir el estrés percibido por el personal sanitario. Las AMPS que abordaron tanto los comportamientos relacionados con la alimentación como con la actividad física fueron más eficaces a la hora de mejorar los resultados en cuanto al peso que las que sólo utilizaron una aproximación. En general, este estudio ofrece información valiosa sobre el impacto de las intervenciones de promoción de la salud en el lugar de trabajo, así como el efecto de las distintas estrategias aplicadas
