Guía de consenso para el abordaje de la neumonía adquirida en la comunidad en el paciente anciano

The incidence of community-acquired pneumonia increases with age and is associated with an elevated morbidity and mortality due to the physiological changes associated with aging and a greater presence of chronic disease. Taking into account the importance of this disease from an epidemiological and prognostic point of view, and the enormous heterogeneity described in the clinical management of the elderly, we believe a specific consensus document regarding this patient profile is necessary. The purpose of the present work was to perform a review of the evidence related to the risk factors for the etiology, the clinical presentation, the management and the treatment of community-acquired pneumonia in elderly patients with the aim of producing a series of specific recommendations based on critical analysis of the literature. This document is the result of the collaboration of different specialists representing the Spanish Society of Emergency Medicine and Emergency Care (SEMES), the Spanish Society of Geriatrics and Gerontology (SEGG), the Spanish Society of Chemotherapy (SEQ), the Spanish Society of Internal Medicine (SEMI), the Spanish Society of Respiratory Medicine and Thoracic Surgery (SEPAR), Spanish Society of Home Hospitalization (SEHAD) and the Spanish Society of Infectious Disease and Clinical Microbiology (SEIMC).     

Evaluación del sufrimiento en la demencia avanzada

Introduction

At the end stage of life of dementia, medical comorbidities are associated with a high degree of patient suffering. The aim of this study was to assess the relationship between the lack of symptoms of discomfort and the level of patient suffering. The relationship with psychological distress and caregiver burden was also clarified.

Material and methods

This study included patients with advanced dementia according to the criteria of the Hospice Enrolment Criteria for End-stage Dementia patients. Patient suffering was assessed with Mini-Suffering State Examination (MSSE). The caregivers were scored by Zarit caregiver burden scale (ZR), and the General Health Questionnaire of Goldberg (GHQ-28). Central tendency and correlation tests were used in the statistical analysis.

Results

The study recorded data from 71 patients. In the comorbidity of medical symptoms associated with advanced dementia, pneumonia (Spearman's rho: −0.29; P=.01), and malnutrition (Spearman's rho: −0.25; P=.03), showed a significant association with the total scale score of MSSE. There were no significant correlations between patient suffering and caregiver psychological distress (r: 0.11; P=.37), or caregiver burden (r: 0.13; P=.32).

Conclusions

The identification of suffering in patients with advanced dementia is recognised by specific symptoms, such as pneumonia and malnutrition. The caregiver’ psychological distress of the caregiver was shown to be unrelated to patient suffering as measured by MSSE.     

Risk Factors for Aspiration Pneumonia in Older Adults

BackgroundsAspiration pneumonia is a dominant form of community-acquired and healthcare-associated pneumonia, and a leading cause of death among ageing populations. However, the risk factors for developing aspiration pneumonia in older adults have not been fully evaluated. The purpose of the present study was to determine the risk factors for aspiration pneumonia among the elderly.ConclusionThe risk factors for aspiration pneumonia were sputum suctioning, deterioration of swallowing function, dehydration, and dementia. These results could help improve clinical management for preventing repetitive aspiration pneumonia.     

The traditional Chinese medicine banxia houpo tang improves swallowing reflex.

A marked depression of swallowing reflex has been found in patients with aspiration pneumonia. We have examined the effects of Banxia Houpo Tang (BHT, Hange Koboku-To in Japanese), on swallowing reflex among the elderly. Thirty-two patients, mean age 74.2 +/- 1.7 years who had at least one episode of aspiration pneumonia, were divided into two groups. Twenty patients took BHT extracts of 7.5 g per day for four weeks, and the other 12 patients took a placebo. The swallowing reflex was measured by a bolus injection of 1 ml of distilled water into the pharynx through a nasal catheter. The reflex was evaluated by the latency time of response, which was the time from the injection to the onset of swallowing. The latency of response decreased significantly from 11.6 +/- 3.0 sec to 2.6 +/- 0.4 sec in the group treated with BHT (p < 0.01), while in the other group with placebo it was from 11.0 +/- 4.0 to 10.8 +/- 3.6 (p > 0.5). Depletion of substance P in the pharynx causes impairments of the swallowing reflex. Substance P in the saliva of treated patients increased from 9.2 +/- 2.5 fmol/ml to 15.0 +/- 2.2 fmol/ml after BHT treatment (p < 0.01), while levels were 8.0 +/- 4.0 fmol/ml before and 7.1 +/- 3.1 fmol/ml after among the placebo group (no significant difference). We suggest that BHT improves the impaired swallowing reflex and may help to prevent aspiration pneumonia in the elderly.     

Efectos del ejercicio físico en la funcionalidad y calidad de vida en mayores institucionalizados diagnosticados de gonartrosis

Introduction

At present, aging and increased life expectancy implies a greater susceptibility to dependence, which then leads to the irreversible loss of quality of life, in many cases due to chronic diseases such as osteoarthritis (OA). The aim of this study was to determine the effect of a treatment based on aerobic exercise in institutionalised elderly people diagnosed with knee osteoarthritis.

Material and method

An experimental, prospective, single blind study was conducted. The sample (n = 31), was divided into two groups. The experimental group (n = 17) was treated based on aerobic exercise for 4 weeks with 2 sessions per week and each lasting 50 minutes. We conducted a pre-test and post-test assessment using a visual analogue scale, WOMAC questionnaire and SF-36 as measuring instruments. The statistical program SPSS15.0 was used for the analysis of the data.

Results

We obtained significant differences in the t-test for paired samples in the three dimensions of the WOMAC questionnaire, P<.001, in the perceived pain P<.001 and in the physical function, vitality and mental health dimensions of the SF-36 with a 95% confidence interval.

Conclusion

Exercise gave positive results in functional (pain, stiffness, physical function) and psychological aspects (mental health and vitality) in the institutionalised elderly.     

1. Reunión Nacional de Trabajo Multidisciplinar en Oncogeriatría: documento de consenso

On 2nd of June 2011 the Institut Català d’ Oncologia l’Hospitalet--Hospital Duran i Reynals hosted the first Meeting of Multidisciplinary Work in Oncogeriatrics. The reason for the meeting, which follows on from an initiative of the Medical Societies of Radiotherapy, Oncology, Geriatrics and Gerontology and Palliative Care and Medical Oncology, was to initiate a joint line of work among the different specialties that generally take part in the handling of the elderly patient suffering from oncologic pathologies. This document summarises the different subjects covered during the Meeting.     

Relación entre el rendimiento en la prueba de estación unipodal y la velocidad del centro de presión en adultos mayores

Introduction

Frequent falls are one of the most important health problems in the elderly population. The unipedal stance test (UPST), asses postural stability and is used in fall risk measures. Despite this, there is little information about its relationship with posturographic parameters (PP) that characterizes postural stability. Center of pressure velocity (CoPV) is one of the best PP that describes postural stability. The aim of this study was to analyze the relation between UST score and CoPV in elderly population.

Materials and methods

A sample of 38 healthy elderly subjects where divided in two groups according to their UPST score, low performance (LP, n = 11) and high performance (HP, n = 27). The correlation between UPST score and COP mean velocity (CoPmV), recorded from a posturographic test, was analyzed between both groups.

Results

An inverse correlation between UPST score and CoPmV was found in both groups. However, this was higher in the LP group (r = −0.69, P = .02) compared to the HP (r = −0.39, P = .04).

Conclusions

Based on the results of this investigation, it may be concluded that the achievement on UPST has an inverse relationship with CoPmV, especially in subjects with low performance in the UPST.     

High correlation between the bacterial species in denture plaque and pharyngeal microflora

Objectives : The morbidity and mortality of the dependent elderly that result from aspiration pneumonia are recognized as a major geriatric health problem. Most cases of bacterial pneumonia are initiated following colonization or superinfection of the pharynx by pathogenic bacteria, followed by aspiration of pharyngeal contents. A recent study revealed that bacteria, that commonly cause respiratory infection, colonized the dentures of dependent elderly. This suggests that denture plaque may function as a reservoir of potential respiratory pathogens to facilitate colonization on the pharynx. The purpose of this study was to determine the possible correlation between denture and pharyngeal microflora. Study Design : The denture and pharyngeal bacterial flora of 50 dependent elderly were examined, and the microorganisms identified by culturing. The agreement between the bacterial species in denture plaque and pharyngeal microflora was investigated using the Kappa method. Results : The microorganism species on the dentures and pharyngeal mucosa of the subjects had an agreement rate of 68.5%. The agreement rate for each of the bacterial species of the dentures and pharynx was also demonstrated to be high. Conclusions : Dentures should be considered an important reservoir of organisations which could colonise the pharynx, and the importance of controlling denture plaque for the prevention of aspiration pneumonia cannot be overemphasized.     

Resultados de la endarterectomía carotídea en pacientes ancianos

Introduction

Forty-five per cent of stoke patients have a surgically accessible stenosis. The objective of our study is to describe the response to carotid endarterectomy (EA) in patients of advanced age compared to younger ones.

Material and method

Retrospective evaluation of the clinical history of all patients who underwent an endarterectomy in a tertiary hospital between January 1995 and December 2006. The patients were grouped into those 75 years or older and those less than this age. The incidence of peri-operative complications in the first month after surgery, and the long-term mortality was evaluated using a survival analysis.

Results

Data were collected on 147 EA in 134 patients of 75 years or more, and on 201 EA in 177 patients less than 75 years-old. The incidence of peri-operative complications was similar in both groups, with a mortality of 2% in the older age group and a stroke incidence of 2.6% (half transient ischaemic accidents). The older patients had a mean follow-up of 4.1 years, with a survival of 86% at one year and 54% at 5 years and with the main cause of death being heart disease.

Conclusions

Carotid EA is a safe and effective technique for the treatment of extracranial carotid stenosis in the elderly, having the same peri-operative morbidity and mortality as younger ones. Age must not affect our therapeutic attitude, although an exhaustive cardiology study must be made in the elderly prior to the operation.     

Effect of Seihai-to, a Kampo medicine, in relapsing aspiration pneumonia an open-label pilot study

Two published case reports described palliation of disease after Seihai-to therapy for refractory aspiration pneumonia caused by recurrent laryngeal nerve paralysis and cerebrovascular disease. We undertook an open-label trial in patients with relapsing aspiration pneumonia. Fifteen patients with relapsing aspiration pneumonia were randomly divided into conventional therapy group (n = 8) or Seihai-to group (n = 7). In Seihai-to group, patients were treated with Seihai-to in addition to conventional therapy (Western medicines). Frequency of feverish days and antibiotics-use, CRP value and chest CT or X-ray findings were compared between the two groups during the study period of 16 weeks. In the Seihai-to group, the latency of swallowing reflex was measured in 6 patients before and after administration of Seihai-to. The mean values of fever index, CRP value and antibiotics-use in the Seihai-to group were decreased significantly, compared with those of the conventional therapy group. However, the latency of the swallowing reflex after 4 weeks of treatment was not significantly changed (p = 0.249), compared with the latency before administration of Seihai-to. No adverse reaction was observed in either group. Seihai-to was effective in reducing relapse of aspiration pneumonia in this small group. Seihai-to might not improve the swallowing reflex, but might instead improve a defense mechanism or excessive inflammation caused by pneumonia in the lower airway. Further evaluation of Seihai-to therapy for patients with aspiration pneumonia in a larger population is warranted.     

Oral health care and aspiration pneumonia in frail older people: a systematic literature review

Objective: To systematically review the literature on oral health care interventions in frail older people and the effect on the incidence of aspiration pneumonia. Background: Oral health care seems to play an important role in the prevention of aspiration pneumonia in frail older people. Methods: Pubmed, Web of Science, Cochrane Library, EMBASE and CINAHL were searched for eligible intervention studies. Only publications with regard to hospitalized or institutionalized older people, who were not dependent on mechanical ventilation were eligible. Two authors independently assessed the publications for their methodological quality. Results: Five publications were included and reviewed. Two studies showed that improvement of oral health care diminished the risk of developing aspiration pneumonia and the risk of dying from aspiration pneumonia directly. The three studies remaining showed that adequate oral health care decreased the amount of potential respiratory pathogens and suggested a reduction in the risk of aspiration pneumonia by improving the swallowing reflex and cough reflex sensitivity. Conclusions: According to the results of the current systematic literature review oral health care, consisting of tooth brushing after each meal, cleaning dentures once a day, and professional oral health care once a week, seems the best intervention to reduce the incidence of aspiration pneumonia.     

La neurólisis del nervio mediano en el paciente anciano: evaluación a largo plazo

Purpose

Carpal tunnel release by opening the flexor retinaculum is considered a satisfactory treatment. However, several factors, like ageing, may influence postoperative results. We present the long term outcomes in elderly patients.

Methods

This is an historical prospective long term study of 52 patients who received surgical treatment of carpal tunnel syndrome when they were 65 or older. We have carried out a clinical-functional (with the Levine questionnaire), electromyographic and dynamometric valuation of the patients studied, up to ten years from the surgery.

Results

The results of Levine's questionnaire, revealed favourable data for a mean follow-up of 10.35 years, with a mean improvement in the clinical score of 1.93 points (95% confidence interval [CI]: 1.72-2.17) and in the functional score of 0.83 points (95% CI: 0.68-0.99). Similarly, the electromyographic values showed a significant improvement compared to preoperative ones (mean difference of sensory velocity of 8.43 m/s, 95% CI: 8.17-11.63; mean difference of motor latency of 1.65 ms, 95% CI: 1.24-2.25). The data on grip strength did not reach statistical significance.

Conclusions

In elderly patients, complete section of the carpal transverse ligament, allows maintaining favourable differences in most of the parameters studied, ten years after surgery, making the surgical treatment a recommendable option.     

Aspiration-Related Deaths in 57 Consecutive Patients: Autopsy Study

Background

Aspiration can cause a diverse spectrum of pulmonary disorders some of which can lead to death but can be difficult to diagnose.

Patients and Methods

The medical records and autopsy findings of 57 consecutive patients in whom aspiration was the immediate cause of death at Mayo Clinic (Rochester, MN, USA) over a 9-yr period, from January 1 2004 to December 31 2012 were analyzed.

Results

The median age at death was 72 years (range, 13–95 years) and included 39 (68%) males. The most common symptom before death was dyspnea (63%) and chest radiography revealed bilateral infiltrates in the majority (81%). Most common precipitating factors for aspiration were depressed consciousness (46%) and dysphagia (44%). Aspiration-related syndromes leading to death were aspiration pneumonia in 26 (46%), aspiration pneumonitis in 25 (44%), and large airway obstruction in 6 patients (11%). Aspiration was clinically unsuspected in 19 (33%) patients. Antimicrobial therapy had been empirically administered to most patients (90%) with aspiration pneumonia and aspiration pneumonitis.

Conclusion

We conclude aspiration-related deaths occur most commonly in the elderly with identifiable risks and presenting bilateral pulmonary infiltrates. One-third of these aspiration-related pulmonary syndromes were clinically unsuspected at the time of death.     

Informe: análisis de las publicaciones de socios de la Sociedad Española de Geriatría y Gerontología del año 2006 al 2011

Data is presented from the survey conducted by the Sociedad Española de Geriatría y Gerontología (SEGG) (Spanish Society of Geriatrics and Gerontology) among its members in order to assess their scientific production between 2006 and 2011, specifically articles in journals that are indexed in the Science Citation Index. The scientific quality of the publications was quantified using the number of times every article was cited and the journal's impact factor. A total of 162 out of the 2450 members responded (6.6%), reporting a total of 903 individual articles, 335 (37%) of them in geriatrics-specific journals, and 568 (63%) in other journals of other specialties. The number of publications increased yearly from 128 in 2006 to 201 in 2010. The scientific quality could be calculated for 530 articles. On average, publications have been cited 8.2 times (median: 2), with the range of citations being from 0 to 242. The average impact factor was 3.1 (median 2.4), ranging from 0 to 53.5. A number of articles have been published in some of the largest impact factor journals, in those of general-interest, as well as geriatrics-specific and basic science journals.     

Guías visuales como herramienta terapéutica en la enfermedad de Parkinson. Una revisión sistemática

Sensory stimuli or sensory cues are being used as a therapeutic tool for improving gait disorders in Parkinson's disease patients, but most studies seem to focus on auditory stimuli. The aim of this study was to conduct a systematic review regarding the use of visual cues over gait disorders, dual tasks during gait, freezing and the incidence of falls in patients with Parkinson to obtain therapeutic implications. We conducted a systematic review in main databases such as Cochrane Database of Systematic Reviews, TripDataBase, PubMed, Ovid MEDLINE, Ovid EMBASE and Physiotherapy Evidence Database, during 2005 to 2012, according to the recommendations of the Consolidated Standards of Reporting Trials, evaluating the quality of the papers included with the Downs & Black Quality Index. 21 articles were finally included in this systematic review (with a total of 892 participants) with variable methodological quality, achieving an average of 17.27 points in the Downs and Black Quality Index (range: 11-21). Visual cues produce improvements over temporal-spatial parameters in gait, turning execution, reducing the appearance of freezing and falls in Parkinson's disease patients. Visual cues appear to benefit dual tasks during gait, reducing the interference of the second task. Further studies are needed to determine the preferred type of stimuli for each stage of the disease.     

Deterioro cognitivo y riesgo de caída en el anciano

Risk of fall is significantly increased in old people with cognitive decline due to specific associations between gait parameters and cognition. This association has recently been demonstrated, there being increasing evidence that cognitive domains such as attention, executive function and types of memory are critical for the correct regulation of gait. Gait disturbances can appear as early predictors of dementia in elderly patients. In the assessment of the fall risk, the use of dual tasks is novel, simple and relevant, especially in cognitive decline. Evidence for interventions in this population is limited, with vitamin D and physical exercise being the most encouraging, for decreasing the risk of fall in dementia.     

Implicaciones de los síntomas depresivos en los ancianos hospitalizados por afección médica

Introduction

Depressive symptoms in hospitalized patients are very common, and they have been related to higher mortality. The aim of the study was to estimate the prevalence of depressive symptoms in hospitalized elderly patients and its relationship to various diseases, as well as their functional and mental status and mortality.

Material and methods

A total of 115 patients over 64 years of age were prospectively studied. The validated Spanish version of the Geriatric Depression Scale of Yesavage (15-item version) was used. Patients were considered to have depressive symptoms if ≥6 points were obtained. The demographic characteristics, the Charlson comorbidity index, the diagnosis at admission, the functional status assessed by the Barthel and Lawton-Brodie index, the mental capacity assessed by the Pfeiffer questionnaire, the length of the hospital stay, and hospital mortality were recorded.

Results

Out of the 115 patients studied, with a mean age of 70.5 years, 71 (61.7%) were female. Depressive symptoms were observed in 46 patients (40%, 95% CI: 34.8-43.9). Patients who died showed a significantly higher score on the Yesavage scale (P=.04). The multivariate analysis showed a significantly independent association between depressive symptoms and functional capacity (P=.026), mental status (P=.021), renal failure (P=.001), liver disease (P=.018), and osteoarthritis (P=.017), but losing the previously seen significant association with diabetes (P=.43).

Conclusions

The prevalence of depressive symptoms in hospitalized elderly patients is high, and is associated with the diagnoses of renal failure, liver disease and osteoarthritis, with a higher comorbidity and especially with a poorer functional capacity.     

¿Qué pacientes se benefician más de la atención geriátrica hospitalaria en opinión de los especialistas en Geriatría?

Objective

To assess the most appropriate criteria considered by geriatricians to select patients who might benefit the most from geriatric hospital care.

Material and methods

We carried out a survey that consisted of various socio-demographic, clinical, functional and mental criteria included in the definition of the geriatric and frail elderly patient. The survey was sent to all specialists in geriatrics in the different hospitals of the Madrid Health Service. They were asked to answer to each criterion indicating whether they considered it as high priority, priority, low priority or no priority. The responses were clustered by type of hospital: acute hospitals with or without a post-graduate geriatric program for medical residents, and medium and long stay hospitals.

Results

A total of 83 questionnaires were completed (70% of the study population): 42 teaching hospitals a post-graduate geriatric program (74% of possible), 20 of those with an emergency department but without a post-graduate geriatric program (56% of possible), and 21 medium and long stay hospitals (84% of potential). All proposed criteria were considered individually as priority or high-priority by more than 50% of respondents. An age 85 years and over, admission for hip fracture, the presence of severe cognitive or functional impairment, frailty, and unexplained deterioration of health status, were considered individually as criteria for selecting high-priority target population by more than 85% of respondents.

Conclusions

Certain criteria, such as advanced age, or the presence of geriatrics-specific conditions, such as hip fracture or severe functional or cognitive impairment, are identified by geriatricians as useful to select patients to receive geriatric specialist hospital care.     

Tafonomía y contexto paleoambiental de los restos de un cetáceo del Mioceno medio de Tarragona (NE España)

A new finding of a marine mammal is documented from the middle Miocene of El Camp basin in Tarragona (NE Spain). The incomplete and disarticulated bone remains belong to the skeleton of a juvenile cetacean. These remains appear deposited above a transgression surface and included within a glauconitic calcisiltite layer. This unit constitutes the beginning of a shallowing-upwards sequence and was deposited under low-energy conditions and low sedimentation rates in a middle-outer platform setting. This context was responsible for the long exposure of the remains and, consequently, an extension of the biostratinomic stage. These conditions favored the natural decomposition and disarticulation of the carcass, allowing the action of different types of scavenging organisms. The interpretation of the paleoenvironmental setting is based in the combination of different datasets: taphonomic data of the bone remains, paleoecologic and taphonomic information provided by the fauna associated to the bones, and ichnologic and sedimentologic interpretation of the sediments where the fossils are included. Combination of such different proxies enables a very good characterization of the paleoenvironmental context of the studied fossils.
