Immune Function, Oxidative, and Inflammatory Markers in Centenarians as Potential Predictors of Survival and Indicators of Recovery After Hospital Admission.

Several parameters of immune function, oxidative, and inflammatory stresses have been proposed as markers of health and predictors of longevity and mortality. However, it is unknown if any of these parameters can be used as predictors of survival in centenarians. Therefore, in a group of 27 centenarians, at the time of admission to the Clinical Hospital of Madrid, a series of immune function, antioxidant, oxidant, and inflammatory parameters were studied. Some centenarians survived and others did not, thus establishing two groups, "survivors" (n = 9) and "nonsurvivors" (n = 18). The results show that surviving centenarians display higher neutrophil chemotaxis and microbicidal capacity, natural killer activity, lymphoproliferation, glutathione reductase activity, and basal interleukin-10 release. Moreover, lower neutrophil and lymphocyte adherence, superoxide anion and malondialdehyde concentrations, and basal release of tumor necrosis factor α are also reported. The odds ratios for survival for these parameters were also calculated, with the highest odds ratios being the lymphoproliferative capacity and the ex vivo basal and stimulated release of interleukin-6 from mononuclear cells (odds ratio = 136.00). Therefore, these parameters have the potential to be used in the clinical setting as predictors of survival in centenarians. In the survivors group, the same parameters were also analyzed after 3 months. Because survivors showed an increase in neutrophil and lymphocyte chemotaxis capacity during the recovery period, reaching similar values to those observed in healthy centenarians, these parameters could be proposed as indicators of recovery.

Diagnóstico del delirium en pacientes con demencia, un gran reto / Diagnosing delirium in patients with dementia, a great challenge

El delirium, a pesar de su alta incidencia, graves consecuencias y potencial reversibilidad, sigue siendo un síndrome infradiagnosticado. En pacientes con demencia, el profesional sanitario puede encontrar dificultades para diferenciar si el paciente presenta alteraciones cognitivas y trastornos conductuales propios de la demencia o, por el contrario, se encuentra ante un cuadro de delirium superpuesto a la demencia (DSD). Ante esta dificultad, se han propuesto en los últimos años distintas herramientas para mejorar el diagnóstico de DSD. Estas herramientas intentan ser fáciles y rápidas de aplicar, y a pesar de centrarse en la evaluación de aspectos cognitivos como la atención o el nivel de consciencia, algunas de ellas han incorporado la valoración de otros aspectos más novedosos, como la capacidad de responder a estímulos externos (estado de alerta o activación) o el grado de movilidad

Delirium, despite its high incidence, serious consequences and potential reversibility, remains an underdiagnosed syndrome. In patients with dementia, the healthcare professional may find significant difficulties in differentiating whether the patient presents cognitive alterations and behavioural disorders characteristic of dementia or, on the contrary, is faced with a delirium superimposed on dementia (DSD). In view of this difficulty, many tools have been proposed in recent years to improve the diagnosis of DSD in these highly complex patients. The aim of these tools is to be easy and quick to apply, and although focusing on assessing cognitive aspects such as attention or level of consciousness, some of them have also incorporated the assessment of other more novel aspects, such as the ability to respond to external stimuli (Arousal) or the degree of mobility

Delayed surgery in hip fracture patients. Can we afford it?

The aim is to analyze whether time to surgery (TtoS) in hip fracture patients is associated with longer than expected length of stay (LofS) and whether there is any particular group in which this is especially relevant. We developed an observational study in Madrid, Spain. From 771 patients admitted to the orthopedic ward, we selected 723 with surgical delay ≤7 days. Age was characterized as younger (<81), elderly (81-90), very elderly (>90). Modified Barthel Index was classified as very dependent (<41), moderately dependent (41-80), independent (>80). RESULTS: Median (IQR) TtoS was 3 (1-4) days; LofS 12 (7-15). Mean age was 84.3 years, 78.4% were women. TtoS was associated with LofS, which increased by 1.80 days (95% CI, 1.50-2.10) per delayed day (p<0.001). After adjustment for age, sex, functional status, we found an increase of 1.75 days (1.46-2.04) per day (p<0.001). We did not find effect of age or sex. Functional status had a higher effect in moderately dependent patients 2.25 days (1.78-2.72) than in very dependent or independent patients, 1.33 (0.37-2.30) and 1.50 days (1.09-1.91) respectively (p 0.012). As conclusion we could affirm that increasing TtoS leads to longer than expected LofS in hip fracture patients, particularly moderately dependent patients. Copyright © 2016 John Wiley & Sons, Ltd.
