Implantación de una Unidad de Ortogeriatría de Agudos en un hospital de segundo nivel

Background

Patients with hip fracture (HF), due to their characteristics, require a specific support. The Acute Orthogeriatric Unit (OGU) has been shown to be one of the most beneficial.

Objective

To evaluate the main variables of HF patients treated at an OGU and compare them with the previous referral model (RC).

Material and methods

A prospective observational study with retrospective control was conducted on 169 patients, split into two groups. In the RC group, patients were admitted to conventional trauma ward. In the OGU group, an early geriatric assessment was performed, and patients were simultaneously attended daily by the orthopaedic surgeon, nurse and geriatrician, and the surgery times, work load, discharge and destination, were planned in a weekly meeting with the rest of professionals.

Results

A total of 71 patients were included in the RC group and 96 in the OGU group. The preoperative characteristics were similar, except for a slightly higher comorbidity in the OGU group. The OGU patients were operated on earlier (3.82±2.08 vs 4.61±2.5 days; P<.32), and overall hospital stay was reduced by 28% (11.84±4.04 vs 16.46±8.4 days; P<.001). The functional efficiency (Barthel Index at discharge-Barthel Index at admission/overall stay - stay before surgery) was higher in the OGU group (1.56±0.7 vs 2.61±1.1; P<.05). There were no differences in functional status, mortality or discharge location.

Conclusions

The OGU is a level of care that provides effective medical care in HF patients in general hospitals.     

Fractura de odontoides en un paciente anciano con mala evolución final: a propósito de un caso y revisión de la bibliografía existente

Odontoid fractures are the most common cervical spine fracture in elderly patients, with falls being the most common mechanism of fracture in these patients. The clinical symptoms range from mild neck pain to quadriplegia, or even death. Treatment options include surgical and non surgical therapies, such as cervical collar or halo vest.     

Experiencia de una Unidad de Prevención de Caídas de un hospital de cuidados intermedios

Introduction

The aim of this study is to determine clinical features and interventions in patients attended in our hospital falls prevention unit.

Material and methods

Medical records and evaluation protocols from October 2010 to June 2012 were reviewed. Results are expressed in means and standard deviation.

Results

We studied 68 patients: 53 came due to falls (77.9%), and 15 (22%) due to gait disorders. The mean age was 77.6±7.9. Number of women: 63 (92.6%). Previous Barthel Index was 94/100, cognitive impairment 23 (33.8%), polypharmacy 69.1%, orthostatic hypotension 18 (26.4%). Walking speed 0.66± 0.19 m/s and Time up and go to (TUG) 16.6±4.5 s. Post-urography detected vestibular dysfunction in 34 patients (77%). Clinical cause of fall and/or gait disorder was multifactorial in 33 (48.5%), Parkinsonism 19 (27.9%), chronic pain/arthropathy 8 (11.4%), and vestibular syndrome 8 (11.4%). Two-thirds (45; 66.1%) of the patients began Physical therapy, and vitamin D was given to 47 (69.1%). Phone calls were made to patients and/or their relatives and noted that after 3 months of the treatment: 48 (70.5%) had no fall; 59 (86.7%) patients followed the recommendations, and 57 (83.8%) were satisfied.

Conclusions

In this sample of older patients, mostly female with a good functional and cognitive condition, the causes of the falls were multifactorial in the half of the cases, and the post-urography detected vestibular changes in the half of the patients.     

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.     

La comparaison à un niveau de référence : un nouveau traitement statistique de données paléoécologiques

The successive levels of a section are compared independently with a reference level (referential) having well identified characters. The comparison is realized by means of a distance or dissimilarity index. The choice of the index as function of the nature of data is argued, as well as the choice of the referential. This new approach is applied to the study of two examples from liassic series of southern France. The treatment of micropaleontological or faciological datas reveals cycles that are coincident with 3rd order eustatic cycles.     

Delirium y delirium subsindrómico: prevalencia de un espectro de enfermedad

Introduction

Subsyndromal delirium (SSD) is a developing concept of disease with a spectrum beyond the diagnostic dichotomy of delirium with standard criteria.

Material and methods

To study the prevalence and significance of SSD we have conducted a cross-sectional prospective multicenter study of all patients admitted to three Geriatric Departments in tertiary hospitals. The SSD diagnostic criteria used were based on Marcantoniós criteria, and the DRS-R-98 scale was also used as a continuous variable of the degree of delirium.

Results

We studied 85 patients, 56% women, Barthel 62 (SD: 32), age 87 (SD: 6), CIRS-G 24 (SD: 6.85). Three quarters (75.3%) of patients had at least one CAM positive item, and half of them with at least 13 points in the DRS-R-98 scale. The prevalence of delirium was 53% and 22.3% for SSD. The degree of delirium-DSS was associated with different geriatric syndromes, levels of malnutrition, and degree of functional and cognitive impairment, with a significant linear trend between groups. Patients without delirium have higher levels than those with subsyndromal delirium, and these in turn are higher than those without diagnosed delirium. There is also a tendency in the degree of delirium measured by the DRS-R-98.

Conclusion

Beyond the dichotomous concept of the presence or absence of delirium, this study suggests the probable continuity of cognitive processes and the possibility of more effective and earlier diagnostic and therapeutic measures     

Apport de l’imagerie hybride TEMP-TDM dans le suivi d’un cancer différencié de la thyroïde

In the management of patients with differentiated thyroid cancer (DTC), abnormalities detected on planar whole body scan and ¹³¹I-SPECT are difficult to interpret because of a lack of anatomical landmarks and limited specificity. Integrated ¹³¹I-SPECT-CT imaging has an additional value for characterization of equivocal tracer uptake seen on planar imaging as well as for precise localization. We illustrate through an observation the incremental diagnostic value of ¹³¹I-SPECT-CT images in the diagnosis of a cervical lymph node mimicking a physiological uptake on planar views. A 35-year-old Tunisian female was followed for papillary thyroid carcinoma, for which she underwent total thyroidectomy and iratherapy. Three years after a complete remission, the thyroglobulin (Tg) level on TSH stimulation increased. Diagnostic planar images with ¹³¹I did not disclose any obvious pathological foci. Furthermore, we noticed an increased ¹³¹I-uptake in the left sub-mandibulary area, which suggested a salivary physiological activity. SPECT-CT of the neck and chest were then performed with a Symbia T camera. Fused images demonstrate that this activity corresponds to a cervical lymph node closely adjacent to sub-mandibulary gland. Management of the patient was then changed. In selected patients with DTC, hybrid imaging should be used as a complementary to planar imaging in terms of diagnostic accuracy, because of superior focus localization and additional anatomic information derived from the CT component. Integrated SPECT-CT is then a useful tool, especially in cases of unclear diagnoses, precising anatomical localization of areas of increased ¹³¹I-uptake and distinguishing malignant lesions from normal physiological uptakes. This is particularly important in an oncologic center, as ours, where we don’t yet have a positron emission tomography (PET) camera is not yet available.     

Calidad de vida percibida por las personas mayores. Consecuencias de un programa de estimulación cognitiva a través de la motricidad «Memoria en movimiento»

Introduction

This article presents the results of evaluation of health related quality of life in a group of elderly people who were engaged in the program of cognitive stimulation «Memory in movement».

Materials and methods

A content analysis was conducted to determine the type of experience that the subjects stated in the context of an interview. The statements were classified into categories created ad hoc. The sample consisted of 32 participants with a mean age of 69.92 ± 4.98 years. The software QSR NVivo-8 was used for data processing.

Results

The results show that the 48% of the elderly perceive some improvements in their memorisation abilities, 47% in attention and concentration, and 10% in the satisfaction with life after being in the program. They are especially worried about the loss of memory -stated by the 65.62%- and they came to the cognitive stimulation program with the aim of improving this capacity. The feelings that participants reported having experienced during the program have to do with fun, vitality and energy.

Conclusions

Programs on cognitive stimulation that incorporate some physical activities, together with a clear playful and social component, improve the psychic and social capacities and they open an important line of intervention due to their good acceptance by the elderly.     

Mise en evidence de l'existence de sensilles chemorecepteurs sur les antennes d'un crustace mysidace cavernicole et de l'intervention de ces sensilles dans la detection d'un extrait de nourriture

The cavernicolous crustacean Antromysis juberthiei showed unexpected behavior when presented with food extract : it avoids the area of odor inflow. This avoidance reaction is reduced by removal of various combinations of antennae and disappears almost with bilateral removal of the first antennae (the aesthetasc-bearing antennules).     

Étude conductimétrique des effets de trois auxines sur un parenchyme de réserve

Conductimetric study of the effects of three auxins on a storage tissue. The change of conductivity of calibrated disks of potato tuber tissue was measured after a 6 h immersion in a mixed aqueous solution of 1 × 10^?3M auxin and 0.2 M mannitol, or pure auxin, or mannitol, of the same concentrations; then measured anew after a l h immersion in 0.1 M KCI. The auxins used were: β-indolyl-acetic acid (AIA), α-naphtyl-acetic acid (ANA) and β-naphtoxyacetic acid (ANOX). A final higher conductivity was observed, the effect increasing from AIA to ANA and ANOX. The physiological significance of the results is discussed.
