Simultaneous Bilateral Quadriceps Tendon Rupture Secondary to Parathyroid Carcinoma: A Case Report.

Simultaneous bilateral quadriceps tendon ruptures are a rare occurrence commonly associated with a traumatic event or systemic disease. A 31-year-old man presented with simultaneous bilateral quadriceps tendon ruptures with associated hyperparathyroidism secondary to parathyroid carcinoma. The injury occurred after the patient attempted to lift a small wooden log from the ground. We discussed the multidisciplinary management of this patient resulting in bilateral quadriceps tendon repairs, tumor resection, and oncological and endocrinological restoration. Clinical follow-up is reported at 15 years after surgery. Parathyroid carcinoma is an extremely rare cancer and rarely the cause of hyperparathyroidism. The systemic effects of the tumor eventually lead to the rupturing of both quadriceps tendons. Orthopaedic physicians must remain vigilant in identifying the root cause of injuries that are atypical in nature.

Surgical care and trauma patients capacity in Piura, Perú - Cross-sectional study.

Introduction: Low and medium income countries face challenges in access and delivery of surgical care, resulting in a high number of deaths and disabled individuals. Objective: To estimate the capacity to provide surgical and trauma care in public hospitals in the Piura region, Perú, a middle income country. Methods: A survey was administered in public hospitals in the Peruvian region of Piura, which combined the Spanish versions of the PIPES and INTACT surveys, and the WHO situational analysis tool. The extent of the event was assessed based in the absolute differences between the medians of the scores estimated, and the Mann-Whitney bilateral tests, according to the geographical location and the level of hospital complexity. Results: Seven public hospitals that perform surgeries in the Piura region were assessed. Three provinces (3/8) did not have any complexity healthcare institutions. The average hospital in the peripheral provinces tended to be smaller than in the capital province in INTACT (8.25 vs. 9.5, p = 0.04). Additionally, water supply issues were identified (2/7), lack of incinerator (3/7), lack of uninterrupted availability of a CT-scanner (5/7) and problems with working hours; in other words, the blood banks in two hospitals were not open 24 hours. Conclusions: There is a significant inequality among the provinces in the region in terms of their trauma care capacities and several shortfalls in the public sector healthcare infrastructure. This information is required to conduct future research on capacity measurements in every public and private institution in the Peruvian region of Piura.

Objetivo: Estimar la capacidad para la atención quirúrgica y de pacientes traumatizados en los hospitales públicos en la región de Piura, Perú, un país de ingreso mediano. Métodos: En los hospitales públicos de la región peruana de Piura se aplicó una encuesta que combinaba las versiones en español de las encuestas PIPES e INTACT y de la herramienta de análisis situacional de la Organizacion Mundial de la Salud (OMS). Se evaluó la magnitud del evento mediante las diferencias absolutas entre las medianas de los puntajes calculados y pruebas bilaterales de Mann-Whitney según la ubicación geográfica y el nivel de complejidad hospitalaria. Resultados: Se evaluaron siete hospitales públicos que realizan cirugía en la región de Piura. Tres provincias (3/8) no contaban con instituciones sanitarias con complejidad de hospital. La mediana de los hospitales de las provincias periféricas tuvo tendencia a ser menor que la de la provincia capital en la INTACT (8,25 vs. 9,5, p = 0,04). Asimismo, se hallaron problemas de abastecimiento de agua (2/7), ausencia de incinerador (3/7), falta de funcionamiento permanente de tomógrafo (5/7) y problemas con el horario de funcionamiento de los bancos de sangre, ya que no funcionaban las 24 horas del día en 2 hospitales (2/7). Conclusiones: Se describe la alta desigualdad entre las provincias de la región en la capacidad de atención de trauma y varias carencias en la infraestructura sanitaria del sector público. Esta información es necesaria para desarrollar futura investigación de medición de capacidades en todos los establecimientos públicos y privados de la región peruana de Piura.

Nonlinear control with friction compensation to swing-up a Furuta pendulum.

Different works in literature have reported that nonlinear controllers based on the energy approach are not effective to completely swing-up an inverted pendulum subjected to friction. Most studies trying to solve this issue consider static friction models in the design of controllers. This consideration is mainly because the stability proof of the system with dynamic friction in closed-loop is difficult. Hence, this paper presents a nonlinear controller with friction compensation to swing-up a Furuta pendulum with dynamic friction. With this aim, we consider that only the active joint of the system is subjected to friction, which is represented via a dynamic model, namely, the Dahl model. We first present Furuta Pendulum dynamic model with dynamic friction. Then, by slightly modifying an energy-based controller that has been previously reported in literature and by including friction compensation, we propose a nonlinear controller that allows to swing-up completely a Furuta pendulum subjected to friction. The unmeasurable friction state is estimated through a nonlinear observer and a stability analysis of the closed-loop system is accomplished with the direct Lyapunov method. Finally, successful experimental results are presented for a Furuta pendulum prototype built by authors. This shows the effectiveness of the proposed controller in achieving a complete swing-up of the Furuta pendulum, in a time feasible for experimental implementation, and ensuring closed-loop stability.

Conclusión: existe un bajo grado de conocimiento y mala actitud ante la violencia infligida en la pareja y esta se presenta en cualquiera de sus formas en las relaciones de pareja.

Factores asociados a la percepción de repercusiones del internado hospitalario peruano durante la COVID-19

Introducción: La pandemia afectó el internado de estudiantes de salud en su asistencia hospitalaria, en la cual realizan las prácticas. Objetivo: Determinar los factores asociados a la percepción de repercusiones del internado hospitalario peruano durante la COVID-19. Métodos: Estudio transversal; se obtuvo estadística descriptiva, analítica bivariada y multivariada basado en una encuesta realizada de forma exploratoria, como parte de otra investigación mayor, a la cual se le asoció variables como edad, sexo, tipo de universidad, estrés, ansiedad, depresión y repercusiones del internado. Resultados: De los 121 encuestados, la mayoría pensó que su familia le hubiese apoyado si se enfermaba de gravedad, que pudo haber infectado a sus familiares o alguna amistad/conocido si acudían al hospital. Muchos estuvieron en desacuerdo con que el hospital o la universidad les darían los implementos de seguridad, por la falta de apoyo de estas entidades. Hubo asociación entre el pensar que se habría contagiado de la COVID-19 si iba al hospital versus el puntaje de ansiedad (p= 0,030), el sexo masculino, según la percepción de que la universidad les daría los materiales para cuidarse (p= 0,029) y el provenir de una universidad privada según el percibir que el hospital no le hubiese apoyado, si se enfermaba de gravedad (p= 0,049). Conclusión: Los factores asociados a la percepción de repercusiones del internado son el apoyo familiar, el poder contagiar a sus familiares, falta de materiales dados por las universidades y hospitales, la ansiedad, el sexo masculino y provenir de universidades privadas.

Introduction: The pandemic affected the internship of health sciences students when they attended the hospital. Objective: To determine the factors associated with the perceived impact of the Peruvian hospital internship during COVID-19. Methods: Cross-sectional; descriptive, bivariate analytical and multivariate statistics were obtained based on an exploratory survey conducted as part of a larger investigation, to which variables such as age, sex, type of university, stress, anxiety, depression, and repercussions of the internship were associated. Results: Of 121 respondents, most of them thought that family would have supported if they have gotten a severe disease. Also, they thought that they could have infected their families or friends/acquaintances if they have gone to the hospital. Many of them disagreed on the statement about the hospital or university providing them safety implements. There was an association between thinking that they could have gotten COVID-19 if they have gone to the hospital versus anxiety score (p= 0,030), being a male according to the perception that the university provided materials to take care of themselves (p= 0,029), and having studied in a private university according to perceiving that the hospital would not have supported them if they have gotten seriously ill (p= 0,049). Conclusion: The factors associated with the perception of repercussions of the boarding school are family support, being able to infect their acquaintances, lack of materials provided by universities and hospitals, anxiety, being male, and coming from private universities.

Source-to-sink partitioning is altered by changes in the expression of the transcription factor AtHB5 in Arabidopsis.

Carbohydrates are transported from source to sink tissues. The efficiency of this transport determines plant growth and development. The process is finely regulated and transcription factors are crucial in its modulation. AtHB5 is a homeodomain-leucine zipper I transcription factor that is repressed during stem maturation. However, its function in this developmental event is unknown. Here, we investigated the expression pattern and role of AtHB5. AtHB5 was expressed in roots, hypocotyls, stems, petioles, pedicels, and central leaf veins. athb5 mutant plants exhibited wider and more lignified stems than controls, whereas AtHB5 overexpressors showed the opposite phenotype. Cross sections of athb5 mutant stems showed enlarged vascular bundle, xylem, phloem, and petiole areas, whereas AtHB5 overexpressors had callose deposits. Several genes involved in starch biosynthesis and degradation had altered transcript levels in athb5 mutants and AtHB5 overexpressors. Rosette and stem biomass was enhanced in athb5 mutants, positively impacting seed yield, protein, and lipid content. Moreover, these effects were more evident in debranched plants. Finally, transport to roots was significantly slowed in AtHB5 overexpressors. Altogether, the results indicated that AtHB5 is a negative modulator of carbon partitioning and sucrose transport from source to sink tissues, and its overexpression diminished plant biomass and seed yield.

Monitoring Indicators of Universal Access to Accessible and Safe Anesthetic and Surgical Care in a Peruvian Region: An Ambispective Study.

INTRODUCTION: The Lancet Commission on Global Surgery indicators for monitoring anesthetic and surgical care allow the identification of access barriers, evaluate the safety of surgeries, facilitate planning, and assess changes over time. The primary objective was to measure these indicators in all health facilities of a Peruvian region in 2020. METHODS: This was an ambispective observational study to measure the anesthetic and surgical care indicators in Piura, a region in Peru, between January 2020 and June 2021. Public and private health facilities in the Piura region that performed surgical care or had specialists from any surgical specialty participated in the study. Data were collected from all regional health facilities that provided surgical care to estimate the density of surgical workforce. Likewise, the percentage of the population with access to an operating room within 2 h was estimated using georeferenced tools. Finally, a public database was accessed to determine the surgical volume, the percentage of the regional population protected with health insurance. RESULTS: In 2020, 88.4% of the inhabitants of this Peruvian region had access to timely essential surgery. There were 18.4 surgical specialists and 1174 surgeries per 100,000 populations, and 91% of the population had health insurance. In addition, there was a rate of 2.1 working operating rooms per 100,000 inhabitants in 2021. CONCLUSIONS: This Peruvian region presented an increasing trend with respect to the population's access to essential and timely surgical care, and health insurance coverage. However, the workforce distribution was inequitable among the provinces of the region, the surgical volume was reduced, and timely access was hindered because of the SARS-CoV-2 pandemic.

Phosphoproteome Analysis Using Two-Dimensional Electrophoresis Coupled with Chemical Dephosphorylation.

Protein phosphorylation is a reversible post-translational modification (PTM) with major regulatory roles in many cellular processes. However, the analysis of phosphoproteins remains the most challenging barrier in the prevailing proteome research. Recent technological advances in two-dimensional electrophoresis (2-DE) coupled to mass spectrometry (MS) have enabled the identification, characterization, and quantification of protein phosphorylation on a global scale. Most research on phosphoproteins with 2-DE has been conducted using phosphostains. Nevertheless, low-abundant and low-phosphorylated phosphoproteins are not necessarily detected using phosphostains and/or MS. In this study, we report a comparative analysis of 2-DE phosphoproteome profiles using Pro-Q Diamond phosphoprotein stain (Pro-Q DPS) and chemical dephosphorylation of proteins with HF-P from longissimus thoracis (LT) muscle samples of the Rubia Gallega cattle breed. We found statistically significant differences in the number of identified phosphoproteins between methods. More specifically, we found a three-fold increase in phosphoprotein detection with the HF-P method. Unlike Pro-Q DPS, phosphoprotein spots with low volume and phosphorylation rate were identified by HF-P technique. This is the first approach to assess meat phosphoproteome maps using HF-P at a global scale. The results open a new window for 2-DE gel-based phosphoproteome analysis.

Comparative Proteomics of Potato Cultivars with a Variable Dormancy Period.

The control of the duration of the dormancy phase is a significant challenge in the potato industry and for seed producers. However, the proteome landscape involved in the regulation of the length of the dormancy period over potato cultivars remains largely unexplored. In this study, we performed for the first time a comparative proteome profiling of potato cultivars with differential duration of tuber dormancy. More specifically, the proteome profiling of Agata, Kennebec and Agria commercial potato varieties with short, medium and medium-long dormancy, respectively, was assessed at the endodormancy stage using high-resolution two-dimensional electrophoresis (2-DE) coupled to reversed-phase liquid chromatography-tandem mass spectrometry (LC-TripleTOF MS/MS). A total of 11 proteins/isoforms with statistically significant differential abundance among cultivars were detected on 2-DE gels and confidently identified by LC-TripleTOF MS/MS. Identified proteins have known functions related to tuber development, sprouting and the oxylipins biosynthesis pathway. Fructokinase, a mitochondrial ADP/ATP carrier, catalase isozyme 2 and heat shock 70 kDa were the proteins with the strongest response to dormancy variations. To the best of our knowledge, this study reports the first candidate proteins underlying variable dormancy length in potato cultivars.

Kidney Disease after Heart and Lung Transplantation.

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as interventions that may help alleviate this serious problem. The impact of pretransplant renal function and the overexaggerated role of chronic nephrotoxicity of calcineurin inhibitors is discussed in detail. Until the exact pathophysiology of kidney disease is better understood, there is a dire need to expand the research agenda beyond observational studies.

Respuesta molecular profunda con ponatinib en leucemia mieloide crónica en fase crónica con resistencia a imatinib y dasatinib: Reporte de caso y revisión de la literatura / Profound molecular response with ponatinib in chronic phase of chronic myeloid leukemia with resistance to imatinib and dasatinib: Case report and review of the literature

RESUMEN Se reporta el caso de una mujer quien a la edad de 54 años fue diagnosticada de leucemia mieloide crónica en fase crónica; inició tratamiento con inhibidor de tirosina cinasa de primera generación, y evidenció falla por ausencia de respuesta hematológica y citogenética. A pesar del cambio de tratamiento a un inhibidor de tirosina cinasa de segunda generación (dasatinib), no fue posible alcanzar niveles óptimos de respuesta, documentándose la positividad para la mutación T315I en dominio ABL de la tirosina cinasa desregulada BCR/ABL, frente a la cual el único medicamento que muestra actividad es ponatinib. Luego de iniciar tratamiento con ponatinib, se evidenciaron niveles óptimos de respuesta citogenética y molecular, así como una adecuada calidad de vida de la paciente.

SUMMARY We report the case of a woman who at the age of 54 years was diagnosed with chronic myeloid leukemia in chronic phase; she began treatment with a first-generation tyrosine kinase inhibitor, and evidenced failure due to the absence of a hematological and cytogenetic response. Despite changing treatment to a second-generation tyrosine kinase inhibitor (dasatinib), it was not possible to achieve optimal levels of response, documenting positivity for the T315I mutation in the ABL domain of the deregulated BCR/ABL tyrosine kinase, compared to ponatinib, the only drug that shows activity. After starting treatment with ponatinib, optimal levels of cytogenetic and molecular response were evidenced, as well as an adequate quality of life for the patient.

En el contexto de la llegada de las vacunas contra la COVID-19 al Perú, es importante conocer que rubros son los más dispuestos a realizarlo. El objetivo de este estudio fue determinar los factores socio-laborales asociados a la posibilidad de vacunación contra la COVID-19 si el trabajo se los exige. Estudio transversal analítico, que tuvo como pregunta principal si es que se vacunarían si es que es requisito para el trabajo, esto se comparó según el rubro laboral, el sexo y el grupo etario; se obtuvo estadística descriptiva y analítica. De los 6628 trabajadores encuestados, el 34% y 35% se vacunarían si es que el trabajo se los pide según el que aún no se enfermaran o que ya lo hubiesen hecho, respectivamente. En el análisis multivariado, hubo mayor frecuencia de estar de acuerdo con el vacunarse entre los que están en el sector de minería (RPa: 1,33; IC95%: 1,05-1,69; valor p=0,019), los que hacen labores domésticas (RPa: 1,14; IC95%: 1,01-1,29; valor p=0,036) y los hombres (RPa: 1,07; IC95%. 1,01-1,14; valor p=0,029); en cambio, a comparación de los más jóvenes, los del rango etario de 40-49 años (RPa: 0,82; IC95%: 0,71-0,95; valor p=0,010) los que pensaban en vacunarse menor frecuencia. Hubo una baja percepción a la posibilidad de vacunarse si es que el trabajo se los pide, siendo los principales factores asociados a la posibilidad de vacunarse el no haberse contagiado previamente de COVID-19, pertenecer al sector minería, realizar labores domésticas y ser hombre(AU)

In the context of the arrival of vaccines against COVID-19 in Peru, it is important to know which sectors are the most willing to be vaccinated. The objective of this study was to determine the socio-labor factors associated with the possibility of vaccination against COVID-19 if required by work. Analytical cross-sectional study, which had as its main question whether they would be vaccinated if it was a job requirement, this was compared according to work category, sex and age group; descriptive and analytical statistics were obtained. Of the 6628 workers surveyed, 34% and 35% would get vaccinated if required to do so by their job, based on whether they had not yet been sick or had already been sick, respectively. In the multivariate analysis, there was a higher frequency of agreement to be vaccinated among those in the mining sector (aPR: 1.33; 95%CI: 1.05-1.69; p-value=0.019), those doing domestic work (aPR: 1.14; 95%CI: 1.01-1.29; p-value=0.036) and men (aPR: 1.07; 95%CI. 1.01-1.14; p-value=0.029); in contrast, those in the younger age range 40-49 years (aPR: 0.82; 95%CI: 0.71-0.95; p-value=0.010) were less likely to be vaccinated than those in the younger age range (aPR: 0.82; 95%CI: 0.71-0.95; p-value=0.010). There was a low perception of the possibility of getting vaccinated if asked to do so at work, the main factors associated with the possibility of getting vaccinated being not having been previously infected with COVID-19, belonging to the mining sector, performing domestic work and being male(AU)

Anesthetic management of a parturient with Marfan syndrome scheduled for cesarean section: case report and review of literature / Manejo anestésico de una parturienta con síndrome de Marfan programada para cesárea: informe de un caso y revisión de la literatura

Abstract: Introduction: Marfan syndrome is an inherited disorder that affects connective tissue. Case: We report the anesthetic management of a parturient with Marfan syndrome scheduled for an elective C-section. Successful use of a combined spinal-epidural technique was used to provide neuraxial anesthesia; however, she presented an unfavorable evolution due to maternal sepsis. Likewise, a literature review of combined spinal-epidural anesthesia for C-sections in Marfan syndrome pregnant women was performed. Conclusion: Anesthetic management of parturients affected by Marfan syndrome during the cesarean section can be challenging. Strict blood pressure control during the intraoperative period has cornerstone importance. Likewise, neuraxial techniques have a significant percentage of failure in these patients.

Resumen: Introducción: El síndrome de Marfan es un desorden hereditario que afecta el tejido conectivo. Caso: Reportamos el manejo anestésico de una parturienta con síndrome de Marfan programada para una cesárea electiva. Para administrar anestesia neuroaxial se utilizó un bloqueo combinado espinal-epidural; sin embargo, la paciente presentó una evolución desfavorable debido a sepsis materna. Asimismo, se realizó una revisión de la literatura del uso de esta técnica anestésica para cesárea en gestantes con síndrome de Marfan. Conclusión: El manejo anestésico de parturientas afectadas por este síndrome puede ser complicado. El control estricto de la presión arterial durante el intraoperatorio tiene importancia fundamental. Además, las técnicas neuroaxiales tienen un porcentaje significativo de fallo en estas pacientes.

The role of left atrial enlargement and age in the prediction of recurrence in embolic strokes of undetermined source.

Objectives: Left atrial disease is an independent risk factor for ischemic stroke and can be used to predict atrial fibrillation (AF). We examine whether left atrial enlargement (LAE) could predict stroke recurrence in patients with embolic stroke of undetermined source (ESUS). Materials and methods: Sixty-four patients with a confirmed diagnosis of ESUS were followed for a median of 22 months. Clinical data and echocardiogram findings were recorded. The echocardiogram interpretation was performed centrally and blindly. The Brown ESUS - AF score was used to categorize patients into high (human resource planning [HRP]: score > 2) and low-risk patients (non-HRP score 0-1). Stroke recurrence was the primary outcome. Results: The median age was 62 years (range: 22-85 years); and 33 (51.6%) were men. The median initial NIHSS score was three points (range: 0-27). Twelve (18.8%) patients were categorized as HRP. We found a significant tendency toward recurrence among HRP versus non-HRP patients. Three (25%) HRP versus 2 (3.8%) non-HRP experienced recurrence (OR: 8.3 95% CI 1.2-57; p=0.042); this association was related to severe atrial dilatation (OR: 14.5 95% CI 0.78-277, p = 0.02) and age > 75 years (OR: 12.7 95% CI 1.7-92.2, p = 0.03). We found no differences in recurrence in a univariate analysis. Conclusions: Patients with severe LAE who are 75 years old or older have a significant tendency to experience stroke recurrence.

Objetivos: La patología atrial izquierda es factor de riesgo independiente para infarto cerebral y puede utilizarse para predecir fibrilación auricular. Examinamos si el crecimiento aurícular izquierdo puede predecir recurrencia en pacientes con infarto embolico de origen indeterminado (ESUS). Materiales y métodos: Sesenta y cuatro pacientes con diagnóstico confirmado de ESUS fueron seguidos por una mediana de seguimiento de 22 meses. Registramos los datos clínicos y ecocardiográficos. La interpretación ecocardiográfica fue centralizada y cegada. La escala de Brown ESUS ­ AF fue utilizada para categorizar a los pacientes en riesgo alto (HRP puntaje > 2) y bajo riesgo (no-HRP: puntaje 0-1). El descenlace primario fue recurrencia de infarto cerebral. Resultados: Mediana de edad fue de 62 años (rango: 22-85 años); 33 (51.6%) fueron hombres. La mediana inicial de la escala de NIHSS fue de 3 putnos (rango de 0 a 27). 12 (18.8%) pacientes fueron de alto riesgo (HRP) y 52 (81.3%) de bajo riesgo (non- HRP). El grupo HRP mostró tendencia significatica hacia mayor recurrencia. Tres (25%) HRP versus 2 (3.8%) no-HRP experimentaron recurrencia (OR: 8.3 IC 95% 1.2-57; p = 0.042); esta asociación se relacionó con dilatación auricular severa (OR: 14.5 IC 95% 0.78-277, p = 0.02) y edad > 75 años (OR: 12.7 IC 95% 1.7-92.2, p = 0.03). En el análisis multivarioado, no encontramos significativas. Conclusiones: El crecimiento auricular izquierdo severo y la edad mayor de 75 años mostraron tendencia significativa a recurrencia de infarto cerebral.

Tres (25%) HRP versus 2 (3.8%) no-HRP experimentaron recurrencia (OR: 8.3 IC 95% 1.2-57; p = 0.042); esta asociación se relacionó con dilatación auricular severa (OR: 14.5 IC 95% 0.78-277, p = 0.02) y edad > 75 años (OR: 12.7 IC 95% 1.7-92.2, p = 0.03). En el análisis multivarioado, no encontramos significativas. Conclusiones: El crecimiento auricular izquierdo severo y la edad mayor de 75 años mostraron tendencia significativa a recurrencia de infarto cerebral.

Calidad de vida y adherencia terapéutica en un programa de hipertensión arterial / Quality of life and therapeutic adherence in a hypertension program

RESUMEN Objetivo Determinar la asociación entre adherencia terapéutica (AT) y calidad de vida relacionada con la salud (CVRS). Materiales y Métodos Se llevó a cabo una investigación transversal en el programa de HTA de un hospital general. Se utilizó el cuestionario SF-36 y la versión española de la prueba de Morisky y Green. Se obtuvieron los puntajes de las dimensiones y componentes sumarios físico (PCS) y mental (MCS). Luego, se ejecutaron los respectivos análisis bivariante y multivariante. Resultados El 39% de los pacientes presentó AT. Los puntajes de todas las dimensiones presentaron asociación estadística con AT. La regresión de Poisson identificó las variables independientes asociadas a la obtención de un puntaje mayor de 50 en PCS [presencia de comorbilidad (factor de riesgo), estado laboral y AT (factores protectores)] y MCS (AT como factor protector). Conclusiones La AT, estado laboral y ausencia de comorbilidad presentaron asociación con una mejor calidad de vida relacionada con la salud.

ABSTRACT Objective To determine the association between treatment adherence and health-related quality of life. Methods and Materials A cross-sectional investigation was performed in an arterial hypertension program of a general hospital. The Spanish version of the Short Form-36 Health Survey and the Spanish version of the Morisky-Green test. The scores of the subscales and Physical Component (PCS) and Mental Component (MCS) summaries of the SF-36 survey were obtained, then the respective bivariate and multivariate analyzes (Poisson regression) were executed. Results 39% of patients had therapeutic adherence. All the dimensions of the SF-36 survey presented a statistical association with adherence to antihypertensive treatment. Poisson regression was executed to identify the independent variables associated with obtaining a score higher than 50 in the PCS [presence of comorbidity (risk factor), work status, and therapeutic adherence (protective factor)] and MCS (therapeutic adherence as a protective factor). Conclusions Therapeutic adherence, work status, and absence of comorbidity were associated with a better health-related quality of life.
