Interprofessional interventions and factors that improve end-of-life care in intensive care units: An integratory review.

INTRODUCTION: The changes in health dynamics, caused by the SARS-COVD-2 pandemic and its consequences, generated a greater need to integrate palliative care in the ICU to promote a dignified death. OBJECTIVE: Identify interprofessional interventions and factors that improve the care of patients at the end of life. METHODOLOGY: Integrative review, including experimental, quasi-experimental, observational, analytical, and descriptive studies with correlation of variables, published from 2010 to 2021, identified in COCHRANE, CINAHL, CUIDEN, LILACS, SCIELO, Dialnet, PsychInfo, PubMed, PROQUES, PSYCHOLOGY, JOURNALS, SCIENCEDIRECT, with MeSH/DECS terms: "Critical Care", "IntensiveCare" "Life support care", "Palliative care", "Life Quality", "Right to die". 36,271 were identified, after excluding duplicate title, abstract, year of publication, design, theme, methodological quality, objectives, and content, 31 studies were found. RESULTS: It included 31 articles, 16.7% experimental, 3.3% quasi-experimental, 80% observational, analytical, and descriptive with correlation of variables, 38% published in the United States, 38%, and 19% in Brazil. The pooled sample was 24,779 participants. 32.2% of the studies had level of evidence 1 recommendation (c), and 25.8% level of evidence 2 recommendation (c). This paper synthesises evidence to promote Interprofessional Collaborative Practice in the ICU, improve end-of-life care, and interventions to achieve established therapeutic goals, implement effective care policies, plans, and programmes for critically ill patients and their families; factors that affect palliative care and improve with training and continuing education for health personnel. CONCLUSION: There are interventions to manage physical and emotional symptoms, training strategies and emotional support aimed at health personnel and family members to improve the quality of death and reduce stays in the ICU. The interdisciplinary team requires training on palliative and end-of-life care to improve care.

Microbiological evaluation of homemade mayonnaise and self-serve acai sold in Araguaína, Tocantins.

Foodborne diseases are common illnesses caused by the consumption of food contaminated with microorganisms, such as viruses, fungi, bacteria, and protozoa. Every year, 600 million people become ill and 420,000 people die as a result of consuming contaminated food. Therefore, food safety is an important issue. In this study, samples of homemade spiced mayonnaise and self-serve acai sold in the city of Araguaína, Tocantins, Brazil were analyzed for microbiological contaminants. Acai was collected from 10 stores, one sample from each store, and tested for mold, yeast, and coliforms, as well as coliform identification and total and thermotolerant coliform counts. Mayonnaise was collected from 20 snack bars, one sample from each. These samples were inoculated on MacConkey and Salmonella Shigella agar plates, and the plates were analyzed for growth. Salmonella spp. were detected in some Mayonnaise samples, and coliforms were detected in all acai samples; 60% of samples had thermotolerant coliforms, and only 40% were within the limits established by ANVISA. The collected samples of mayonnaise and acai were contaminated with molds and yeasts above the established limit of 103 CFU/g. Thus, the analyzed mayonnaise and acai samples were contaminated and unfit for consumption, demonstrating the importance of hygienic-sanitary measures in food handling.

Indicadores asistenciales y estándares de calidad asistencial para la psicología clínica en los centros de salud mental del Sistema Madrileño de Salud evaluados por sus profesionales / Care indicators and standards of quality of care for clinical psychology in the mental health centers of the Madrid Health System evaluated by their professionals

La disponibilidad en España de indicadores y estándares de calidad asistencial para Psicología Clínica en el Sistema Nacional de Salud es limitada. En este trabajo analizamos indicadores y estándares asistenciales ambulatorios informados por 107 Facultativos de Psicología Clínica en Centros de Salud Mental del Servicio Madrileño de Salud, a través de una encuesta online completada en 2021. El tiempo medio para la primera consulta normal en adultos fue de 4 meses y 5 en infanto-juvenil. El tiempo medio entre sesiones en ambos fueron 7 semanas. El número medio de pacientes nuevos semanales es de 8 y 6 en adultos e infanto-juvenil y de pacientes diarios fue de 9 y 8 respectivamente. La carga media total es 328 pacientes en adultos y 280 en infanto-juvenil. Sin embargo, los encuestados creen que la carga de pacientes activos debería ser 74, sin superar los 150 y un máximo de 6 al día. La mayoría de los psicólogos/as clínicos/as propone aumentar el número de plazas PIR y apoya la creación de Servicios de Psicología Clínica. La carga asistencial supera las recomendaciones de otros expertos. Se concluye que es imprescindible aumentar la ratio de psicólogos/as clínicos/as para alcanzar los estándares recomendados (AU)

Chronic immunoglobulin maintenance therapy in myasthenia gravis.

BACKGROUND AND PURPOSE: Long-term treatment of myasthenia gravis (MG) includes symptomatic and course-modifying therapies that target the immune system. Recently, both intravenous immunoglobulin (IVIG) and subcutaneous immunoglobulin (SCIG) have emerged as viable options for chronic therapy, considering the favourable safety-efficacy profile and possible immunosuppressant sparing properties. The aim was to investigate the outcomes of the long-term care of generalized MG with immunoglobulin (Ig). METHODS: This is a retrospective, repeated-measures design study. Charts of generalized MG patients, treated with IVIG/SCIG for at least 6 months, from January 2015 to January 2020, were analysed. The primary outcome was the mean change in Myasthenia Gravis Impairment Index (MGII) after treatment with Ig, comparing baseline to IVIG and SCIG treatment periods. Secondary outcomes included the changes in pyridostigmine, immunosuppressive medications and patient-reported outcome 'percentage of normal' (0%-100%). RESULTS: Thirty-four patients were treated with chronic Ig therapy (30 IVIG/SCIG, three SCIG, one IVIG). The mean durations of IVIG and SCIG periods were 21.8 ± 19.4 (range 3-64) months and 19.5 ± 11.3 (range 5-45) months respectively. There was a significant reduction in MGII scores (27.7 ± 15.7 baseline; 22.0 ± 17.4 IVIG period; 19.5 ± 18.1 SCIG period; F = 17.9; d.f. = 1.7; P < 0.01), pyridostigmine and immunosuppressant use (P = 0.00). The outcome 'percentage of normal' had a significant positive association with both treatments (P = 0.00). CONCLUSION: Our study results suggest that patients can be successfully transitioned to IVIG and from IVIG to SCIG in the chronic treatment of generalized MG with reductions in impairments and use of other medications and improvement in overall status with Ig therapy. Prospective, randomized studies are needed to clarify costs and comparative effectiveness.

Identificación por catálogo y detección molecular de bovinos Holstein portadores de braquiespina en Uruguay / Identification through sire catalogues analysis and molecular detection of brachyspina carriers in Uruguayan Holstein

Resumen El síndrome de braquiespina es una condición genética de la raza Holstein, detectada en el año 2006. Es causado por una deleción de 3.3 Kb en el gen FANCI localizado en el cromosoma bovino 21. La mutación fue identificada en poblaciones de Holstein de Europa, América del Norte y Asia. Dada la importancia económica del defecto y su amplia distribución mundial, el objetivo de este trabajo ha sido la identificación de animales portadores en el núcleo de selección genética de la raza en Uruguay y el diagnóstico molecular del alelo deletéreo en animales del rodeo nacional. En el presente estudio se analizaron 2598 registros de toros Holstein del catálogo de padres del sistema de evaluación genética lechera, los registros de toros pertenecientes a los catálogos de semen Holstein disponible para Uruguay de los años 2014 al 2018; y 71 vacas pertenecientes al rodeo general. Se encontraron 28 toros portadores de braquiespina de un total de 377 toros con información genética del catálogo de padres y cuatro vacas portadoras de un total de 71 genotipificadas en nuestro laboratorio. Se demostró una disminución en el ingreso de semen de animales portadores al país entre los años 2014 y 2018. La frecuencia significativa de animales portadores en Uruguay evidencia la necesidad de implementar estrategias que permitan eliminar gradualmente el defecto de la población.

Abstract Brachyspina syndrome is a hereditary recessive disease of recent identification in the Holstein breed. It is caused by a deletion of 3.3Kb in the FANCI gene located in the bovine chromosome 21. The mutation was identified in Holstein populations of Europe, North America and Asia. Given the economic importance of the defect and its wide distribution, the objective of this work was the identification of carrier animals in the genetic selection nucleus of the breed in Uruguay and the molecular verification of the deleterious allele in animals of the national herd. In the present study, 2598 records of Holstein bulls were analyzed from the list of parents of the dairy genetic evaluation system, records of bulls belonging to the Holstein semen catalogs available for Uruguay from 2014 to 2018; and 71 cows belonging to the general herd. Twenty-eight brachyspina carrier bulls were found of a total of 377 bulls with genetic information from the list of parents and four carrier cows of a total of 71 genotyped in our laboratory. A decrease in the income of semen from carrier animals to the country between 2014 and 2018 was demonstrated. The significant frequency of carrier animals in Uruguay evidences the need to implement strategies to gradually eliminate the population defect.

Potentially inappropriate medications in older adults living with HIV.

OBJECTIVES: We assessed the prevalence of potentially inappropriate medication (PIM) among older (≥ 65 years) people living with HIV (O-PLWH) in the region of Madrid. METHODS: We analysed the dispensation registry of community and hospital pharmacies from the Madrid Regional Health Service (SERMAS) for the period between 1 January and 30 June 2017, looking specifically at PIMs according to the 2019 Beers criteria. Co-medications were classified according to the Anatomical Therapeutic Chemical (ATC) classification system. RESULTS: A total of 6 636 451 individuals received medications. Of these individuals, 22 945 received antiretrovirals (ARVs), and of these 1292 were O-PLWH. Overall, 1135 (87.8%) O-PLWH were taking at least one co-medication, and polypharmacy (at least five co-medications) was observed in 852 individuals (65.9%). A PIM was identified in 482 (37.3%) O-PLWH. Factors independently associated with PIM were polypharmacy [adjusted odds ratio (aOR) 7.08; 95% confidence interval (CI) 5.16-9.72] and female sex (aOR 1.75; 95% CI 1.30-2.35). The distribution of PIMs according to ATC drug class were nervous system drugs (n = 369; 28.6%), musculoskeletal system drugs (n = 140; 10.8%), gastrointestinal and metabolism drugs (n = 72; 5.6%), cardiovascular drugs (n = 61; 4.7%), respiratory system drugs (n = 13; 1.0%), antineoplastic and immunomodulating drugs (n = 10; 0.8%), and systemic anti-infectives (n = 2; 0.2%). Five drugs accounted for 84.8% of the 482O PLWH with PIMs: lorazepam (38.2%), ibuprofen (18.0%), diazepam (10.2%), metoclopramide (9.9%), and zolpidem (8.5%). CONCLUSIONS: Prescription of PIMs is highly prevalent in O-PLWH. Consistent with data in uninfected elderly people, the most frequently observed PIMs were benzodiazepines and nonsteroidal anti-inflammatory drugs . Targeted interventions are warranted to reduce inappropriate prescribing and polypharmacy in this vulnerable population.

Lugar de fallecimiento de las personas con enfermedades susceptibles de cuidados paliativos en las diferentes comunidades autónomas de España / Place of death of people with conditions needing palliative care in the different autonomous communities (regions) of Spain

FUNDAMENTO: Conocer el lugar de fallecimiento por causas susceptibles de cuidados paliativos de personas residentes en España de 15 o más años de edad según la comunidad autónoma (CA), y cómo influyen las causas (oncológicas y no oncológicas). MÉTODO: Estudio transversal de base poblacional con análisis de los certificados médicos de defunción entre 2012 y 2015. Los efectos ajustados de las variables sociodemográficas, la CA y las causas sobre el lugar de fallecimiento se estimaron mediante las odds de fallecimiento en hospital frente a domicilio (OH/D) y en residencia frente a domicilio (OR/D), y las odds ratio (ORH/D y ORR/D) obtenidas por regresión logística multinomial. RESULTADOS: Se produjeron 1.611.767 muertes de las que 64,8% correspondieron a la población diana. La defunción en hospital fue un 77% más frecuente que en domicilio, y en residencia un 53% menor. Sexo masculino, menor edad, bajo nivel de estudios, lugar de nacimiento fuera de España, tamaño de municipio grande y estado civil no casado se asociaron a fallecimiento en hospital, y las mismas excepto sexo femenino y mayor edad a residencia. Las OH/D ajustadas fueron > 1 en todas las CA y las OR/D < 1, excepto Cataluña. Para las causas oncológicas, las ORH/D ajustadas disminuyeron y fueron significativamente <1 en casi la mitad de CA, y todas las ORR/D permanecieron <1. CONCLUSIONES: El fallecimiento se produjo mayoritariamente en hospital y menos en residencia, aunque las causas oncológicas aumentan la probabilidad de fallecer en domicilio en vez de en hospital (efecto ajustado)

BACKGROUND: Dying at home is the most frequent preference, with the institutionalized context being the most common place of death. To determine the place of death in conditions requiring palliative care of residents in Spain aged 15 or over by Autonomous Community (AC) and to examine the relationship with oncological vs. non-oncological causes of death. METHODS: Population-based cross-sectional study analysing medical death certificates. Adjusted effects of socio-demographic variables, AC and causes on the place of death were estimated calculating odds of death in hospital vs. at home (OH/H) and in a nursing home vs. at home (ON/H), and odds ratio (ORH/H and ORN/H) by multinomial logistic regression models. RESULTS: During 2012-2015, 1,611,767 deaths were recorded, 64.8% corresponding to the target population. Death in hospital was 77% more frequent than death at home, while death in a nursing home was 53% lower. Male sex, lower age, lower academic level, place of birth other than Spain, bigger city size and civil status other than married displayed a relationship with death in hospital, while the same variables except female sex and higher age did so in a nursing home. Adjusted OH/H > 1 and ON/H < 1 were observed in all AC, except Catalonia. Oncological causes made OH/H < 1 in almost 50% of AC, while ON/H continue to be < 1. CONCLUSIONS: Most deaths were in hospital and fewer at nursing homes, despite oncological causes increasing deaths at home (adjusted effect)

Adjusted O-H/H higher than 1 and O-N/H lower than 1 were observed in all AC, except Catalonia. Oncological causes made O-H/H lower than 1 in almost 50% of AC, while O-N/H continue to be lower than 1. CONCLUSIONS: Most deaths were in hospital and fewer at nursing homes, despite oncological causes increasing deaths at home (adjusted effect).

Two-dimensional speckle tracking echocardiography demonstrates no effect of active acromegaly on left ventricular strain.

BACKGROUND: Speckle tracking echocardiography (STE) allows for the study of myocardial strain (ε), a marker of early and subclinical ventricular systolic dysfunction. Cardiac disease may be present in patients with acromegaly; however, STE has never been used to evaluate these patients. OBJECTIVE: To evaluate left ventricular (LV) global longitudinal strain in patients with active acromegaly with normal LV systolic function. DESIGN: Cross-sectional clinical study. METHODS: Patients with active acromegaly with no detectable heart disease and a control group were matched for age, gender, arterial hypertension and diabetes mellitus underwent STE. Global LV longitudinal ε (GLS), left ventricular mass index (LVMi), left ventricular ejection fraction (LVEF) and relative wall thickness (RWT) were obtained via two-dimensional (2D) echocardiography using STE. RESULTS: Thirty-seven patients with active acromegaly (mean age 45.6 ± 13.8; 48.6% were males) and 48 controls were included. The mean GLS was not significantly different between the acromegaly group and the control group (in %, -20.1 ± 3.1 vs. -19.4 ± 2.2, p = 0.256). Mean LVMi was increased in the acromegaly group (in g/m2, 101.6 ± 27.1 vs. 73.2 ± 18.6, p < 0.01). There was a negative correlation between LVMi and GLS (r = -0.39, p = 0.01). CONCLUSIONS: Acromegaly patients, despite presenting with a higher LVMi when analyzed by 2D echocardiography, did not present with impairment in the strain when compared to a control group; this finding indicates a low chance of evolution to systolic dysfunction and agrees with recent studies that show a lower frequency of cardiac disease in these patients.

Efficacy of Change to New P2Y12 Receptor Antagonists in Patients High on Treatment Platelet Reactivity Undergoing Percutaneous Coronary Intervention.

Selective intensification of platelet inhibition may improve high on treatment platelet reactivity (HPR). We evaluated the efficacy of dual-antiplatelet therapy, including clopidogrel (CPG), compared to new P2Y12-receptor antagonists in patients with HPR undergoing percutaneous coronary intervention, regarding the outcome of composite major adverse cardiac events (MACEs, including death, acute coronary syndrome [ACS], and stent restenosis). The presence of HPR (71 of 181 patients) almost doubled the risk of MACEs. The new antiplatelet agent reduced MACEs (45.8%, 26%, and 16.7% for CPG, prasugrel, and ticagrelor [TGL]; RR 0.36; 0.13-0.98, P = .03, TGL), specifically in patients with ACS. Failure to reduce HPR after the antiplatelet change and diabetes were independent predictors for MACEs. The HPR was early and effectively reduced after changing the antiplatelet therapy, but the intensity of this reduction did not significantly decrease the risk of MACEs. These findings support the benefit of HPR-guided intensification of platelet inhibition. Whether the intensity of this reduction improves the patient's clinical outcomes deserves further investigation.

[Differential effects of diabetes education programs by levels of HbA1c and the presence of chronic complications in patients with type 1 diabetes]. / Efectos diferenciales de los programas de educación en diabetes según los niveles de HbA1c y la presencia de complicaciones crónicas en el paciente ti.

BACKGROUND: Diabetes Education Programs (DEP) that improve metabolic control are applied to a wide variety of patient types. The aim is to test whether DEPs work differently depending on the patient profile. MATERIALS AND METHODS: Thirty-six type 1 diabetics participated. They were divided into four groups according to their haemoglobin levels (range: 7-13 %) and into two groups according to the presence or absence of complications. The ECODI scale for assessing diabetes knowledge and the Frequency of Self-Care scale were completed by all patients. RESULTS: The results showed that HbA1c decreased after the DEP, with some areas of self-care also improving. There were no changes, however, to diet or exercise. CONCLUSIONS: DEP appear to work better in patients with worse control and with complications, suggesting that they have a certain role to play in prevention. Their lack of impact on diet or exercise, would suggest that the DEPs require improvement to include psychological strategies that motivate lasting lifestyle changes.

Efectos diferenciales de los programas de educación en diabetes según los niveles de HbA1c y la presencia de complicaciones crónicas en el paciente tipo 1 / Differential effects of diabetes education programs by levels of HbA1c and the presence of chronic complications in patients with type 1 diabetes

Fundamento: Los programas de Educación Diabetológica (PED) mejoran el control metabólico pero son aplicados a pacientes de muy diversa índole. El objetivo es comprobar si un PED funciona de manera diferente según el perfil del paciente. Material y Métodos: Participaron en el estudio 36 pacientes diagnosticados de diabetes tipo 1. Fueron segmentados en cuatro grupos según niveles de hemoglobina (rango de 7-13%) y en dos, según la presencia o no de complicaciones. Todos cumplimentaron la Escala ECODI y la de Frecuencia de Auto-Cuidado. Resultados: Se comprueba cómo tras el PED existe una disminución de la Hb1Ac y algunas áreas del auto-cuidado también mejoran, pero no hay cambios en dieta ni en el ejercicio. Conclusiones: El PED parece funcionar mejor en los pacientes con peor control y con complicaciones, y se discute, por tanto, su papel preventivo. Se concluye sobre la necesidad de mejorar la intervención, ya que no hay cambios en aspectos relativos a los factores de riesgo cardiovascular, incluyendo estrategias psicológicas que motiven un cambio real en el estilo de vida (AU)

The allergenic structure of the thaumatin-like protein Ole e 13 is degraded by processing of raw olive fruits.

BACKGROUND: The thaumatin-like protein (TLP) Ole e 13 in raw olive fruit is responsible for occupational allergy in olive oil mill workers. However, these workers do not experience allergic symptoms after ingestion of edible olive. OBJECTIVES: To analyze the presence of IgE-reactive TLP in raw and edible olive fruit and to assess the allergenic potency of both sources. METHODS: The content of TLP in raw and edible olive fruit protein extracts was analyzed using immunoblotting with sera from allergic patients and with olive TLP-specific IgG. The structural and immunological stability of TLP were assayed using immunoblotting after treatment of both raw olive and purified TLP with 0.25 M NaOH solution for 24 hours. Olive pollen extract was investigated by immunoblotting for TLP content. RESULTS: The TLP contained in raw olive fruit was not present in edible olives as a result of maceration before human consumption. No TLP was detected in olive pollen using specific IgG or sera from patients allergic to olive fruit. Sera from patients allergic to olive pollen did not react with purified TLP. CONCLUSIONS: IgE-reactive TLP is not present in edible olive, thus explaining the low number of patients allergic to this highly consumed fruit. Patients allergic to olive pollen are not sensitized toTLP and, therefore, not expected to be at risk of food allergy to olive fruit or TLP plant sources.

Introducción: La aceituna natural contiene una proteína de la familia de las taumatinas (TLP) que es responsable de la alergia ocupacional en trabajadores de molinos de aceite. Sin embargo, éstos no presentan síntomas cuando ingieren aceitunas comestibles. Objetivos: Analizar la presencia de TLP en aceituna natural y comestible, y correlacionar sus niveles con la potencia alergénica de ambos productos. Métodos: El contenido de TLP en los extractos proteicos de las aceitunas fue analizado por inmunotransferencia y tinción con sueros de pacientes alérgicos así como con antisuero específico para TLP de olivo. La estabilidad estructural e inmunológica de la TLP se ensayó mediante inmunotinción después del tratamiento del extracto de aceituna natural y de la TLP purificada con NaOH 0.25 M durante 24 h. También se analizó la presencia de TLP en el polen de olivo por inmunotinción. Resultados: La TLP presente en la aceituna natural no se detecta en la comestible como consecuencia del tratamiento de maceración al que es sometida para obtener el producto apto para el consumo humano. No se observó TLP reactiva en el polen de olivo, ni con anticuerpos específicos ni con sueros de pacientes alérgicos a aceituna. Sueros de pacientes alérgicos al polen de olivo no reaccionan con la TLP purificada de aceituna. Conclusiones: La TLP de olivo no está presente en las aceitunas comestibles lo que explica el escaso número de pacientes alérgicos a la aceituna. Además, los pacientes alérgicos al polen de olivo no están sensibilizados a TLP, por lo que no tendrían riesgo de sufrir alergia alimentaria a aceitunas o a fuentes vegetales de TLPs (AU)

Aspirin resistant patients with recent ischemic stroke.

Some patients with a recent ischemic stroke who are being treated with aspirin as an antiaggregant suffer a new ischemic stroke. These patients (15-25%) have been called unresponsive to aspirin or aspirin resistant. The aspirin-resistant patients have a four-time greater risk of suffering a stroke. Furthermore, these strokes are generally more severe, with increased infarct volume and greater risk of recurrence. There is currently no ideal laboratory test to detect the resistance to the antiaggregant effect of aspirin. The study of resistance to aspirin would only be indicated in selected cases. In these patients, one should first rule out any "pseudo-resistance" to aspirin (lack of compliance, concomitant treatments that interfere with the action of the aspirin).
