Development of a Clinical Prediction Rule for Adverse Events in Multimorbid Patients in Emergency and Hospitalisation.

(1) Background: There is currently a global consensus that the quality of comprehensive care for acutely hospitalised elderly people should include addressing functionality and mobility, cognitive status, prevention of pressure ulcers, urinary incontinence, falls and delirium, as well as pain control and medication-related problems. The aim of this study is to develop and validate a clinical prediction rule for multimorbid patients admitted to an acute care hospital unit for any of the five adverse events included in our vulnerability pentad: falls, pressure ulcers, urinary incontinence, pain and delirium. (2) Methods: Longitudinal analytical clinimetric study, with two cohorts. The study population will consist of multimorbid patients hospitalised for acute care, referred from the Emergency Room. A clinical prediction rule will be proposed, incorporating predictive factors of these five adverse outcomes described. This study has received funding, awarded in November 2020 (PI-0107-2020), and was approved in October 2019 by the Research Ethics Committee ″Costa del Sol″. (3) Conclusions: Preventing adverse events in hospitalised patients is particularly important for those with multimorbidity. By applying a clinical prediction rule to detect specific risks, an estimate can be obtained of their probability of occurrence.

Health-Related Quality of Life and Use of Hospital Services by Patients with Heart Failure and Their Family Caregivers: A Multicenter Case-Control Study.

BACKGROUND: Heart failure (HF) causes high rates of hospital admissions. It is known that disease progression impacts the health-related quality of life (HRQoL) of both patients and caregivers, yet to date, this finding is based on cross-sectional studies with limited samples. OBJECTIVES: The study aim is to analyze the relationship between HF patients' use of hospital services (a proxy for disease progression) and the HRQoL of their family caregivers. METHODS: This work is a multicenter nested case-control study on a population of patients admitted to hospitals in southern Spain due to heart failure. The sample comprised 530 patient-caregiver dyads. Hospital admission data were retrospectively collected for the 5 years prior to inclusion in the study. Bivariate analyses and multivariate logistic regression were used to determine associations between patient deterioration and caregivers' quality of life. RESULTS: Patients' use of hospital services was associated with worsened quality of life for family caregivers, with an overall OR of 1.48 (95% CI: 1.23-1.79). A positive correlation was found between patients' perceptions of their physical health and the perceived mental health of caregivers (r = 0.127, p = 0.004) and between the perceived mental health of both (r = 0.291; p <0.0001). CONCLUSIONS: Greater use of hospital services by patients with HF is an independent predictor of deterioration of family caregivers' HRQoL. The physical and mental components of patients' and their family caregivers' HRQoL interact and influence each other. Additional factors, such as the nature and intensity of care provided, also determine the worsening of a family caregiver's HRQoL. CLINICAL RELEVANCE: These results can be used to identify family caregivers of people with heart failure at risk of suffering a deterioration in their health-related quality of life. Increased use of hospital services is an independent predictor of the deterioration of the family caregivers' health-related quality of life. Since clinical nurses are the main provider who gives support and education to family caregivers, they should be alert to this situation and individualize interventions to prevent this deterioration.

ADCK2 Haploinsufficiency Reduces Mitochondrial Lipid Oxidation and Causes Myopathy Associated with CoQ Deficiency.

Fatty acids and glucose are the main bioenergetic substrates in mammals. Impairment of mitochondrial fatty acid oxidation causes mitochondrial myopathy leading to decreased physical performance. Here, we report that haploinsufficiency of ADCK2, a member of the aarF domain-containing mitochondrial protein kinase family, in human is associated with liver dysfunction and severe mitochondrial myopathy with lipid droplets in skeletal muscle. In order to better understand the etiology of this rare disorder, we generated a heterozygous Adck2 knockout mouse model to perform in vivo and cellular studies using integrated analysis of physiological and omics data (transcriptomics-metabolomics). The data showed that Adck2+/- mice exhibited impaired fatty acid oxidation, liver dysfunction, and mitochondrial myopathy in skeletal muscle resulting in lower physical performance. Significant decrease in Coenzyme Q (CoQ) biosynthesis was observed and supplementation with CoQ partially rescued the phenotype both in the human subject and mouse model. These results indicate that ADCK2 is involved in organismal fatty acid metabolism and in CoQ biosynthesis in skeletal muscle. We propose that patients with isolated myopathies and myopathies involving lipid accumulation be tested for possible ADCK2 defect as they are likely to be responsive to CoQ supplementation.

Utility of an immunocapture-agglutination test and an enzyme-linked immunosorbent assay test against cytosolic proteins from Brucella melitensis B115 in the diagnosis and follow-up of human acute brucellosis.

The utility of an immunocapture-agglutination (Brucellacapt, Vircell SL, Granada, Spain) test and an enzyme-linked immunosorbent assay IgG, IgA, and IgM (ELISA-IgG, ELISA-IgA, ELISA-IgM) against cytosolic proteins from Brucella melitensis B115 (R) was compared with ELISA-IgG, ELISA-IgA, and ELISA-IgM against smooth lipopolysaccharide (S-LPS) from B. melitensis 16M (S), serum agglutination test (SAT), and Coombs test in the diagnosis and follow-up for 10 months of 51 patients with acute brucellosis. The sensitivities of ELISA tests against cytosolic proteins varied from 49.0 % for ELISA-IgG to 64.7% for ELISA-IgM and were lower than the sensitivities showed by ELISA S-LPS (from 88.2% to 92.2%), SAT (88.2%), Coombs (96.1%), and Brucellacapt (98.0%) tests. Specificity was over 93% in all cases. The evolutionary behavior of the SAT, Coombs, and Brucellacapt tests was similar. There was a decrease of between 20% and 40% in antibody titer in the 10th month of evolution after treatment. The evolutional curves of IgG, IgA, and IgM against cytosolic protein increased slightly till the eighth month. The specific IgM and IgA antibodies against protein fractions began to show a drop from the eighth month on, showing levels slightly lower than the initial sera values by the end of the 10th month. In this month, titers of specific IgG against proteins fractions remained higher than the titers showed by the initial sera.

Diagnóstico de laboratorio y evolución serológica de pacientes con tularemia / Laboratory diagnosis and serologic evolution of patients with tularemia

Fundamento: La tularemia era una enfermedad prácticamente inexistente en España hasta finales de 1997, cuando se declaró un brote epidémico en nuestra comunidad. El objetivo de nuestro trabajo ha sido estudiar los datos existentes sobre el diagnóstico microbiológico de 55 pacientes que sufrieron tularemia. Pacientes y métodos: Se obtuvieron 32 muestras para cultivo pertenecientes a 19 pacientes y 151 sueros correspondientes a 55 pacientes. El diagnóstico serológico se realizó mediante seroaglutinación en tubo y microaglutinación. En todos los sueros se realizó una seroaglutinación de Wright (SAW) y un test de Coombs frente a Brucella y seroaglutinaciones frente a Yersinia enterocolitica O:9, Yersinia enterocolitica O:3 y Proteus OX 19. Resultados: Se aisló F. tularensis en dos muestras (6,25 por ciento) de las 32 estudiadas. Se obtuvieron títulos mayores o iguales a 1/160 en el 78,2 por ciento y en el 74,5 por ciento de los sueros iniciales por sero-aglutinación en tubo y microaglutinación, respectivamente. La correlación entre las dos pruebas fue de 0,80 (p < 0,001). Se observó fenómeno de prozona en el 59,9 por ciento de los sueros, y reactividad cruzada frente a Brucella y Proteus OX19 en el 9,3 y el 22,8 por ciento, respectivamente. No se observó reactividad cruzada con Y. enterocolitica O:3 y O:9. Conclusiones: El cultivo de F. tularensis es poco sensible. La correlación obtenida entre la seroaglutinación en tubo y microaglutinación es buena. Ambas técnicas son útiles en el diagnóstico de la tularemia, con algunas ventajas de la microaglutinación sobre la aglutinación. (AU)
