Mapping trust relationships in organ donation and transplantation: a conceptual model.

The organ donation and transplantation (ODT) system heavily relies on the willingness of individuals to donate their organs. While it is widely believed that public trust plays a crucial role in shaping donation rates, the empirical support for this assumption remains limited. In order to bridge this knowledge gap, this article takes a foundational approach by elucidating the concept of trust within the context of ODT. By examining the stakeholders involved, identifying influential factors, and mapping the intricate trust relationships among trustors, trustees, and objects of trust, we aim to provide a comprehensive understanding of trust dynamics in ODT. We employ maps and graphs to illustrate the functioning of these trust relationships, enabling a visual representation of the complex interactions within the ODT system. Through this conceptual groundwork, we pave the way for future empirical research to investigate the link between trust and organ donation rates, informed by a clarified understanding of trust in ODT. This study can also provide valuable insights to inform interventions and policies aimed at enhancing organ donation rates.

An innovative approach to improve the detection and treatment of risk factors in poor urban settings: a feasibility study in Argentina.

BACKGROUND: The effective management of cardiovascular (CVD) prevention among the population with exclusive public health coverage in Argentina is low since less than 30% of the individuals with predicted 10-year CVD risk ≥10% attend a clinical visit for CVD risk factors control in the primary care clinics (PCCs). METHODS: We conducted a non-controlled feasibility study using a mixed methods approach to evaluate acceptability, adoption and fidelity of a multi-component intervention implemented in the public healthcare system. The eligibility criteria were having exclusive public health coverage, age ≥ 40 years, residence in the PCC's catchment area and 10-year CVD risk ≥10%. The multi-component intervention addressed (1) system barriers through task shifting among the PCC's staff, protected medical appointments slots and a new CVD form and (2) Provider barriers through training for primary care physicians and CHW and individual barriers through a home-based intervention delivered by community health workers (CHWs). RESULTS: A total of 185 participants were included in the study. Of the total number of eligible participants, 82.2% attended at least one clinical visit for risk factor control. Physicians intensified drug treatment in 77% of participants with BP ≥140/90 mmHg and 79.5% of participants with diabetes, increased the proportion of participants treated according to GCP from 21 to 32.6% in hypertensive participants, 7.4 to 33.3% in high CVD risk and 1.4 to 8.7% in very high CVD risk groups. Mean systolic and diastolic blood pressure were lower at the end of follow up (156.9 to 145.4 mmHg and 92.9 to 88.9 mmHg, respectively) and control of hypertension (BP < 140/90 mmHg) increased from 20.3 to 35.5%. CONCLUSION: The proposed CHWs-led intervention was feasible and well accepted to improve the detection and treatment of risk factors in the poor population with exclusive public health coverage and with moderate or high CVD risk at the primary care setting in Argentina. Task sharing activities with CHWs did not only stimulate teamwork among PCC staff, but it also improved quality of care. This study showed that community health workers could have a more active role in the detection and clinical management of CVD risk factors in low-income communities.

Left-sided infective endocarditis caused by Streptococcus agalactiae: rare and serious.

A comparative study of the behaviour of left-sided infective endocarditis (left-sided IE) due to Streptococcus agalactiae (GBS) with left-sided IE caused by Staphylococcus aureus (SA). A prospective, multicentre cohort study in eight public hospitals in Spain, from January 1984 to December 2015; comparative analysis and factors associated with mortality. In total, there were 1754 episodes of left-sided IE; 41 (2.3%) caused by GBS vs. 344 (19.6%) due to SA, definitive IE 39 vs. 324 cases, males, 25 vs. 213, respectively. There were no differences in age or comorbidity, and healthcare-associated acquirement was 10% vs. 43%, p 0.001. Transthoracic echocardiogram (TTE) was performed in 95% vs. 96.8% and a transesophageal echocardiogram (TEE) in 61% vs. 56%. Vegetations were detected in 80% and measured > 1 cm in a similar proportion. It affected native valves in 85.4% vs. 82.6% and late prosthetic valve in 14.6% vs. 9.6%. The course was acute in both groups. There were more skin manifestations in SA left-sided IE, 7.3% vs. 32%, p 0.001. Both groups had similar complications, but in SA, there was more renal failure, 24% vs. 45%, p 0.010. Surgical risk and operated patients were similar. Mortality was proportionally higher in the SA group, without significance 29% vs. 43% (150), p 0.09. Heart failure, septic shock and neurological deterioration conditioned mortality: HR 1.96, 1.69 and 1.37 (CI 95% 1.40-2.73; 1.19-2.39 and 0.99-1.88 respectively) and to a lesser degree SA as aetiology agent and age. Left-sided IE caused by GBS is similar in severity to left-sided IE caused by SA.

Infective endocarditis in patients with bicuspid aortic valve: Clinical characteristics, complications, and prognosis. / Endocarditis infecciosa sobre válvula aórtica bicúspide: características clínicas, complicaciones y pronóstico.

INTRODUCTION: Bicuspid aortic valve (BAV) is the most frequent congenital cardiac disease. It is associated to a higher risk of cardiovascular complications, including infective endocarditis (IE). METHODS: Retrospective, observational and single centre study that included all patients with IE diagnosed between 1996 and 2014. An analysis was made of the epidemiological, clinical, microbiological and echocardiographic data, complications during hospital admission, need for surgery, in-hospital mortality, and 1-year follow-up. Cases with endocarditis on prosthetic valves or other locations were excluded, as well as those for which the aortic valve morphology had not been accurately defined. A comparative statistical analysis was performed between BAV and tricuspid (TAV). RESULTS: Of a total of 328 cases with IE, 118 (35.67%) were on aortic valve, with 18 (16.22%) of them being BAV. The BAV cases were younger than TAV (51±19.06 vs. 60.83±15.73 years, P=.021) and they had less comorbidity (Charlson 0.67±0.77 vs. 1.44±1.64, P=.03).). There was a higher tendency of Staphylococcal origin (38.9 vs. 21.5%, P=.137), and 55.6% showed peri-valvular complications (TAV 16.1%, P=.001), in particular, abscesses (38.9 vs.16.1%, P=.047). BAV was the only predictive factor of peri-valvular complications (OR 7.87, 95% CI; 2.38-26.64, P=.001). Patients with BAV had more surgery during their admission (83.3 vs. 44.1%, P=.004), had less in-hospital mortality, with no statistical significance (5.6 vs. 25.8%, P=.069), and 1-year survival was significantly superior (93.8 vs 69.3%, P=.048). CONCLUSIONS: Patients with IE on BAV are young, with low comorbidity. They frequently present with peri-valvular complications and they often require early surgery. Compared to TAV cases, in-hospital mortality is lower and 1-year survival is significantly higher.

Induction of immunogenic apoptosis by blockade of epidermal growth factor receptor activation with a specific antibody.

Despite promising results in the use of anti-epidermal growth factor receptor (EGFR) Abs for cancer therapy, several issues remain to be addressed. An increasing emphasis is being placed on immune effector mechanisms. It has become clear for other Abs directed to tumor targets that their effects involve the adaptive immunity, mainly by the contribution of Fc region-mediated mechanisms. Given the relevance of EGFR signaling for tumor biology, we wonder whether the oncogene inhibition could contribute to Ab-induced vaccine effect. In a mouse model in which 7A7 (an anti-murine EGFR Ab) and AG1478 (an EGFR-tyrosine kinase inhibitor) displayed potent antimetastatic activities, depletion experiments revealed that only in the case of the Ab, the effect was dependent on CD4(+) and CD8(+) T cells. Correspondingly, 7A7 administration elicited a remarkable tumor-specific CTL response in hosts. Importantly, experiments using 7A7 F(ab')(2) suggested that in vivo Ab-mediated EGFR blockade may play an important role in the linkage with adaptive immunity. Addressing the possible mechanism involved in this effect, we found quantitative and qualitative differences between 7A7 and AG1478-induced apoptosis. EGFR blocking by 7A7 not only prompted a higher proapoptotic effect on tumor metastases compared with AG1478, but also was able to induce apoptosis with immunogenic potential in an Fc-independent manner. As expected, 7A7 but not AG1478 stimulated exposure of danger signals on tumor cells. Subcutaneous injection of 7A7-treated tumor cells induced an antitumor immune response. This is the first report, to our knowledge, of a tumor-specific CTL response generated by Ab-mediated EGFR inhibition, suggesting an important contribution of immunogenic apoptosis to this effect.

Communication of medical errors in a simulated clinical scenario. Experience with a pediatric residency group.

OBJECTIVE: To determine the performance of groups of pediatric residents from a Buenos Aires hospital, in terms of correct recognition and communication of a medical error (ME), in a high-fidelity simulation scenario. To describe the reactions and communication attempts following the ME and the self-perception by the trainees before and after a debriefing. METHODS: Quasi-experimental uncontrolled study conducted in a simulation center. First- and third-year pediatric residents participated. We designed a simulation case in which an ME occurred and the patient deteriorated. During the simulation, participants had to provide information on communicating the ME to the patient's father. We assessed communication performance and, additionally, participants completed a self-perception survey about ME management before and after a debriefing. RESULTS: Eleven groups of residents participated. Ten (90.9%) identified the ME correctly, but only 27.3% (n=3) of them reported that a ME had occurred. None of the groups told the father they were going to give him important news concerning his son's health. All 18 residents who actively participated in this communication completed the self-perception survey, with an average score before and after debriefing of 5.00 and 5.05 (out of 10) (p=0.88). CONCLUSIONS: We observed a high number of groups that recognized the presence of a ME, but the communication action was substantially low. Communication skills were insufficient and residents' self-perception of error management was regular and not modified by the debriefing.

Family bereavement and organ donation in Spain: a mixed method, prospective cohort study protocol.

INTRODUCTION: There is a discrepancy in the literature as to whether authorising or refusing the recovery of organs for transplantation is of direct benefit to families in their subsequent grieving process. This study aims to explore the impact of the family interview to pose the option of posthumous donation and the decision to authorise or refuse organ recovery on the grieving process of potential donors' relatives. METHODS AND ANALYSIS: A protocol for mixed methods, prospective cohort longitudinal study is proposed. Researchers do not randomly assign participants to groups. Instead, participants are considered to belong to one of three groups based on factors related to their experiences at the hospital. In this regard, families in G1, G2 and G3 would be those who authorised organ donation, declined organ donation or were not asked about organ donation, respectively. Their grieving process is monitored at three points in time: 1 month after the patient's death, when a semistructured interview focused on the lived experience during the donation process is carried out, 3 months and 9 months after the death. At the second and third time points, relatives' grieving process is assessed using six psychometric tests: State-Trait Anxiety Inventory, Beck Depression Inventory-II, Inventory of Complicated Grief, The Impact of Event Scale: Revised, Posttraumatic Growth Inventory and Connor-Davidson Resilience Scale. Descriptive statistics (means, SDs and frequencies) are computed for each group and time point. Through a series of regression models, differences between groups in the evolution of bereavement are estimated. Additionally, qualitative analyses of the semistructured interviews are conducted using the ATLAS.ti software. ETHICS AND DISSEMINATION: This study involves human participants and was approved by Comité Coordinador de Ética de la Investigación Biomédica de Andalucía (CCEIBA) ID:1052-N-21. The results will be disseminated at congresses and ordinary academic forums. Participants gave informed consent to participate in the study before taking part.

CONCLUSIÓN: El ámbito universitario es un espacio ideal para el abordaje de actividades de promoción y prevención de estos FR.

The Use of 2 e-Learning Modalities for Diabetes Education Using Facebook in 2 Cities of Argentina During the COVID-19 Pandemic: Qualitative Study.

BACKGROUND: The COVID-19 pandemic and the confinement that was implemented in Argentina generated a need to implement innovative tools for the strengthening of diabetes care. Diabetes self-management education (DSME) is a core element of diabetes care; however, because of COVID-19 restrictions, in-person diabetes educational activities were suspended. Social networks have played an instrumental role in this context to provide DSME in 2 cities of Argentina and help persons with diabetes in their daily self-management. OBJECTIVE: The aim of this study is to evaluate 2 diabetes education modalities (synchronous and asynchronous) using the social media platform Facebook through the content of posts on diabetes educational sessions in 2 cities of Argentina during the COVID-19 pandemic. METHODS: In this qualitative study, we explored 2 modalities of e-learning (synchronous and asynchronous) for diabetes education that used the Facebook pages of public health institutions in Chaco and La Rioja, Argentina, in the context of confinement. Social media metrics and the content of the messages posted by users were analyzed. RESULTS: A total of 332 messages were analyzed. We found that in the asynchronous modality, there was a higher number of visualizations, while in the synchronous modality, there were more posts and interactions between educators and users. We also observed that the number of views increased when primary care clinics were incorporated as disseminators, sharing educational videos from the sessions via social media. Positive aspects were observed in the posts, consisting of messages of thanks and, to a lesser extent, reaffirmations, reflections or personal experiences, and consultations related to the subject treated. Another relevant finding was that the educator/moderator role had a greater presence in the synchronous modality, where posts were based on motivation for participation, help to resolve connectivity problems, and answers to specific user queries. CONCLUSIONS: Our findings show positive contributions of an educational intervention for diabetes care using the social media platform Facebook in the context of the COVID-19 pandemic. Although each modality (synchronous vs asynchronous) could have differential and particular advantages, we believe that these strategies have potential to be replicated and adapted to other contexts. However, more documented experiences are needed to explore their sustainability and long-term impact from the users' perspective.

[Feminist public health, another view on the pandemic.] / Por una salud pública feminista, otra lectura sobre la pandemia.

Theorists of the ethics and politics of care, with their feminist and intersectional analyses, have spent decades trying to leave their mark on clinical practice and political structures . In them, extensive processes of humanization of the relationship between professionals and people who need their care are required, without neglecting inequalities due to gender, social class or belonging to vulnerable minority groups that go through health and disease experiences in the community. society. It is evident that our institutions must be extensively rethought in their foundations; from nursing homes to highly technological ICUs; from the saturation of primary care to the lack of specialized personnel. In areas such as nursing, great emphasis is placed on models based on interdependence and the particular context to generate another care framework , while fighting for hierarchies and invisibilities related to highly feminized professions . Not surprisingly, the reflections that follow are signed by three women with hybrid profiles who have dedicated part of our working life to the field of primary and hospital care (both in nursing and in physiotherapy) and, in turn, to research and teaching in bioethics, philosophy and humanities. We have experienced in our flesh the contradictions between a will to serve and some axes of oppression connatural to the institutions.

Las teóricas de las éticas y políticas del cuidado, con sus análisis en clave feminista e interseccional, llevan décadas intentando dejar huella en la práctica clínica y en las estructuras políticas . En ellas, se requieren amplios procesos de humanización de la relación entre profesionales y personas que necesitan su atención, sin dejar de lado las desigualdades por motivos de género, clase social o pertenencia a colectivos vulnerables minoritarios que atraviesan las vivencias de salud y enfermedad en la sociedad. Es evidente que nuestras instituciones deben ser ampliamente repensadas en sus fundamentos; desde las residencias de ancianos a las UCI altamente tecnologizadas; desde la saturación de la atención primaria a la falta de personal especializado. En ámbitos como la enfermería se hace gran hincapié en los modelos basados en la interdependencia y el contexto particular para generar otro marco de asistencia , a la vez que se lucha por las jerarquías e invisibilidades relacionadas con las profesiones altamente feminizadas . No en vano las reflexiones que siguen las firman tres mujeres con perfiles híbridos que hemos dedicado parte de nuestra vida laboral al ámbito de la atención primaria y hospitalaria (tanto en enfermería como en fisioterapia) y, a su vez, a la investigación y la docencia en bioética, filosofía y humanidades. Hemos vivido en nuestras carnes las contradicciones entre una voluntad de servicio y unos ejes de opresión connaturales a las instituciones.

[Left-sided endocarditis due to gram-negative bacilli: epidemiology and clinical characteristics]. / Endocarditis sobre válvulas izquierdas por bacilos gran negativos: epidemiología y características clínicas.

INTRODUCTION: The aim of this study is to describe the epidemiological, clinical characteristics, and outcome of patients with left-side endocarditis caused by gram-negative bacteria. METHOD: Prospective multicenter study of left-sided infective endocarditis reported in the Andalusian Cohort for the Study of Cardiovascular Infections between 1984 and 2008. RESULTS: Among the 961 endocarditis, 24 (2.5%) were caused by gram-negative bacilli. The most common pathogens were Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica. Native valves (85.7%) were mainly affected, most of them with previous valve damage (57%). Comorbidity was greater (90% vs 39%; P=.05) than in endocarditis due to other microorganism, the most frequent being, diabetes, hepatic cirrhosis and neoplasm. A previous manipulation was found in 47.6% of the cases, and 37% were considered hospital-acquired. Renal failure (41%), central nervous system involvement (33%) and ventricular dysfunction (45%) were the most frequent complications. Five cases (21%) required cardiac surgery, mostly due to ventricular dysfunction. More than 50% of cases were treated with aminoglycosides, but this did not lead to a better outcome or prognosis. Mortality (10 patients) was higher than that reported with other microorganisms (41% vs 35%; P=.05). CONCLUSIONS: Left-sided endocarditis due to gram-negative bacilli is a rare disease, which affects patients with major morbidities and often with a previous history of hospital manipulations. Cardiac, neurological and renal complications are frequent and associated with a high mortality. The association of aminoglycosides in the antimicrobial treatment did not involve a better outcome or prognosis.

Prevalence of leg ulcers in the province of Cuenca: a study in Primary Care. / Prevalencia de las úlceras de pierna en la provincia de Cuenca: un estudio en Atención Primaria.

OBJECTIVE: To determine the prevalence of leg ulcers, and to describe the affected patients, wounds, and treatment. METHOD: Observational, cross-sectional prevalence study. An ad hoc online questionnaire was sent to all nurses attending Primary Care centres of the "Gerencia de Atención Integrada de Cuenca" (Integrated Care Management of Cuenca, Spain). Data regarding patient sociodemographic and clinical variables, lesion characteristics and the type of intervention (concerning prevention and treatment) were collected. RESULTS: In total, 152 professionals (response rate=98.1%) completed the questionnaire, collecting data from 131,190 inhabitants. A total of 63 patients (75.5±12.6 years old) with 75 ulcers were identified, finding an overall prevalence of 0.480‰ (CI 95%: 0.375-0.614), distributed as: venous ulcer 0.274‰ (n=36), diabetic foot 0.145‰ (n=19), and arterial ulcer 0.061‰ (n=8). The prevalence was similar regarding gender (0.535‰ vs. 0.426‰, respectively, p=.365), but men exhibited more diabetic foot (0.214‰ vs. 0.076‰, p=.037). In all three types of lesions prevalence increased with age, reaching 1.743‰ in 64+age group. The median of the leg ulcer duration and corrected area were 190.0±340.0 days and 5.0±13.7cm2, respectively, with a recurrence rate of 74.7%. CONCLUSIONS: The prevalence of chronic leg ulcers was lower than that reported in other studies, although with high recurrence rates. Overall estimators from previous studies may have overestimated the prevalence, especially in regions with a high rural component.

Taking Particle Tracking into Practice by Novel Software and Screening Approach: Case-Study of Oral Lipid Nanocarriers.

The success on the design of new oral nanocarriers greatly depends on the identification of the best physicochemical properties that would allow their diffusion across the mucus layer that protects the intestinal epithelium. In this context, particle tracking (PT) has arisen in the pharmaceutical field as an excellent tool to evaluate the diffusion of individual particles across the intestinal mucus. In PT, the trajectories of individual particles are characterized by the mean square displacement (MSD), which is used to calculate the coefficient of diffusion (D) and the anomalous diffusion parameter (α) as MSD=4Dτα. Unfortunately, there is no stablished criteria to evaluate the goodness-of-fit of the experimental data to the mathematical model. This work shows that the commonly used R2 parameter may lead to an overestimation of the diffusion capacity of oral nanocarriers. We propose a screening approach based on a combination of R2 with further statistical parameters. We have analyzed the effect of this approach to study the intestinal mucodiffusion of lipid oral nanocarriers, compared to the conventional screening approach. Last, we have developed software able to perform the whole PT analysis in a time-saving, user-friendly, and rational fashion.

Ampicillin Plus Ceftriaxone Combined Therapy for Enterococcus faecalis Infective Endocarditis in OPAT.

Ampicillin plus ceftriaxone (AC) is a well-recognized inpatient regimen for Enterococcus faecalis infective endocarditis (IE). In this regimen, ceftriaxone is usually administered 2 g every 2 h (AC12). The administration of AC in outpatient parenteral antibiotic treatment (OPAT) programs is challenging because multiple daily doses are required. AC regimens useful for OPAT programs include once-daily high-dose administration of ceftriaxone (AC24) or AC co-diluted and jointly administered in bolus every 4 h (ACjoined). In this retrospective analysis of prospectively collected cases, we aimed to assess the clinical effectivity and safety of three AC regimens for the treatment of E. faecalis IE. Fifty-nine patients were treated with AC combinations (AC12 n = 32, AC24 n = 17, and ACjoined n = 10). Six relapses occurred in the whole cohort: five (29.4%) treated with AC24 regimen and one (10.0%) with ACjoined. Patients were cured in 30 (93.3%), 16 (94.1%), and eight (80.0%) cases in the AC12, AC24 and ACjoined groups, respectively. Unplanned readmission occurred in eight (25.0%), six (35.3%), and two (20.0%) patients in the AC12, AC24 and ACjoined groups, respectively. The outcome of patients with E. faecalis IE treated with AC in OPAT programs relies on an optimization of the delivery of the combination. AC24 exhibit an unexpected rate of failures, however, ACjoined might be an effective alternative which clinical results should corroborate in further studies.

Communication of medical errors in a simulated clinical scenario. Experience with a pediatric residency group / Comunicação de erros médicos em cenário clínico simulado. Experiência com residentes em Pediatria

ABSTRACT Objective: To determine the performance of groups of pediatric residents from a Buenos Aires hospital, in terms of correct recognition and communication of a medical error (ME), in a high-fidelity simulation scenario.

RESUMO Objetivo: Determinar o desempenho de grupos de residentes pediátricos de um hospital de Buenos Aires, em termos de reconhecimento e comunicação correta de um erro médico (EM),em cenário de simulação. Descrever as reações e tentativas de comunicação após o EM e a autopercepção pelos estagiários antes e depois de um questionário. Métodos: Estudo quase experimental não controlado realizado em centro de simulação. Participaram residentes pediátricos do primeiro e terceiro anos. Concebeu-se um caso de simulação em que ocorreu um EM com deterioração de um paciente. Durante a simulação, os participantes tiveram que fornecer informações relacionadas à comunicação do EM ao pai do paciente. Avaliou-se o desempenho da comunicação e, adicionalmente, os participantes completaram um inquérito de autopercepção sobre a gestão da EM, antes e depois de um questionário. Resultados: Onze grupos de residentes participaram. Dez (90,9%) identificaram corretamente o EM, mas apenas 27,3% (n=3) deles comunicaram que havia ocorrido o EM. Nenhum dos grupos disse ao pai que iria dar notícias importantes sobre a saúde do seu filho. Todos os 18 residentes que participaram ativamente da comunicação completaram o questionário de autopercepção com uma pontuação média antes e depois do questionário de 5,00 e 5,05 (máximo: 10 pontos) (p=0,88). Conclusões: Observamos elevado número de grupos que reconheceram a presença de um EM, mas a ação de comunicação foi rara. A capacidade de comunicação foi insuficiente e a autopercepção da gestão de erros por parte dos residentes foi regular, não sendo modificada pelo debriefing.

Soil management effects on aggregate dynamics in semiarid Aragon (NE Spain).

During decades, in semiarid rainfed Aragon, intensive soil tillage and low crop residue input have led to the loss of soil structure and soil degradation. Conservation tillage and cropping intensification can improve soil structure in these areas. The objective of this study was to determine the influence of three different tillage systems (traditional tillage, reduced tillage and no-tillage) under two cropping systems (fallow-barley rotation and barley monoculture) on soil aggregation dynamics during a cropping season. A decrease in tillage intensity resulted in a higher mean size of dry aggregates and a greater water aggregate stability in both cropping systems particularly under no-tillage.

Estudio de la adherencia al tratamiento en pacientes con la enfermedad de Parkinson desde la farmacia comunitaria y las asociaciones de Parkinson de la Región de Murcia / Study of the treatment adherence in patients with Parkinson's disease from the community pharmacy and the Parkinson associations from the Region of Murcia

Introducción: La falta de adherencia al tratamiento farmacológico es uno de los principales problemas en pacientes con enfermedades crónicas. Una falta de adherencia se relaciona con un aumento de la discapacidad y de los costes sanitarios. El objeti-vo principal de este artículo es conocer el grado de adherencia al tratamiento en pacientes con la enfermedad de Parkinson. Método: se ha realizado un estudio observacional, longitudinal y prospectivo en colaboración con la Federación de Asociaciones de Parkinson de la Región de Murcia (FEPAMUR) y farmacias colabo-radoras de la Región de Murcia. Se llevó a cabo un procedimiento de recogida de datos demográficos del paciente (sexo y edad) con el fin de caracte-rizarlos, y se evaluó la adherencia al tratamiento mediante el Test de Morisky-Green y el test de Hermes.Resultados: Al estudiar la adherencia con el Test de Morisky-Green se aprecia que el 64% obtuvo una adherencia baja al tratamiento, el 19% presentó una adherencia media, mientras que sólo el 17% de los pacientes fue muy adherente. Según el test de Hermes se observa que un 42% de los pacientes son adherentes al tratamiento. Conclusiones: Existe una baja adherencia al trata-miento farmacológico, según el test de Hermes y el test de Morisky-Green. En función del sexo se con-cluye que las mujeres son más adherentes que los hombres y si nos enfocamos en la edad, se erigen como más adherentes aquellos pacientes con una edad menor a 60 años. (AU)

Introduction: Lack of adherence to drug treatment is one of the main problems in patients with chronic diseases. A lack of adherence is related to an in-crease in disability and healthcare costs. The main objective of this article is to evaluate the degree of adherence to treatment in patients with Parkinson's disease. Method: An observational, longitudinal and pros-pective study has been carried out in collaboration with the Federation of Parkinson's Associations of the Region of Murcia (FEPAMUR) and collaborating pharmacies of the Region of Murcia. A patients demographic data collection procedure (sex and age) was carried out in order to characterize them. Besides, adherence to treatment was evaluated using the Morisky-Green test and the Hermes test.Results: When studying adherence with the Moris-ky-Green Test, it could be seen that 64% had low adherence to treatment, 19% had medium adhe-rence, while only 17% of the patients were highly adherent. According to the Hermes test, it was observed that 42% of the patients were adherent to treatment.Conclusions: There is a low adherence to pharma-cological treatment, according to the Hermes test and the Morisky-Green test. According to sex, we conclude that women are more adherent than men, and if we focus on the age, patients under 60 years of age are more adherent. (AU)
