Disnea y psicopatología en el paciente anciano con enfermedad pulmonar obstructiva crónica

Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease with dyspnoea perception as a main symptom. In severe stages, dyspnoea can constitute a risk factor for depression, anxiety and somatization disorders.

Objective

The objective was to evaluate the presence of these psychopathologies based on dyspnoea and severity stages in patients with COPD.

Materials and methods

Patients (n=51) were evaluated by means of the Hospital Anxiety and Depression Scale, the dyspnoea scale (MRC), the General Health Questionnaire (GHQ-28) and spirometric criteria.

Results

The increase in dyspnoea level and disease severity lead to a progressive worsening of anxiety, depressive and somatic symptoms with clinical relevance (P<0.05). There was a significant correlation between those parameters (P<0.05).

Conclusions

The early detection and treatment of these psychopathologies associated with dyspnoea and progression of the disease must be taken into account in this complex pathology.     

El carcinoma diferenciado incidental de tiroides es menos prevalente en la enfermedad de Graves que en el bocio multinodular

ObjectiveRisk factors for differentiated thyroid carcinoma (DTC) are poorly understood, but serum TSH levels, thyroid nodularity, and presence of autoimmunity are well-recognized factors that modulate DTC prevalence. TSH stimulates proliferation of both normal and neoplastic follicular cells. Consequently, thyroid-stimulating immunoglobulins (TSI), because of its TSH-like action, should induce DTC progression in patients with Graves’ disease (GD). The study objective was to compare the prevalence of incidental DTC in patients undergoing thyroidectomy for benign thyroid disease.MethodsThe pathology reports of 372 patients with preoperative diagnosis of euthyroid multinodular goiter (EMG) or hyperthyroidism were reviewed. Scintigraphy results and serum TSI levels were used to diagnosed either GD or hyperactive MG (HMG) to hyperthyroid subjects. Prevalence of DTC in each category was calculated using a Chi-square test.ResultsEMG, GD, and HMG were diagnosed in 221, 125, and 26 patients. There were 58 DTCs, distributed as follows [n (%)]: EMG, 49 (22.2%); GD, 8 (6.4%), and HMG, 1 (3.8%). Difference in prevalence of incidental DTC between the groups was statistically significant (p < 0.001). After adjustment for age, patients with EMG had a greater DTC prevalence than GD patients, with an OR of 4.17 (p < 0.001). Tumor size (mm, mean ± SD) was 6.92 ± 11.26, 1.97 ± 1.85, and 9.0 for EMG, GD and HMG respectively (p = 0.017).ConclusionsIncidental DTC was less prevalent in GD as compared to EMG irrespective of age. This finding may suggest a predisposition to develop DTC in patients with thyroid nodular disease and/or a potential effect of autoimmunity to protect against development of neoplastic disease.     

Experiencia con el uso del registrador implantable de eventos en una serie de personas mayores con caídas y sospecha de síncopes de origen arrítmico

Objective

To review our experience on using an implantable loop recorder (ILR) in patients with recurrent falls, when an arrhythmogenic cause is suspected.

Material and methods

This is a retrospective, observational study of patients with repetitive unexplained falls, suspected syncope, or electrocardiographic abnormalities. All of them had been evaluated by a cardiologist, who decided to implant a loop recorder (ILR) for an accurate diagnosis.

Results

A total of 13 patients received an ILR. The average falls rate for the sample was 3.3. The mean age was 78 years, and 46% were female, with a mean follow-up period of 24 months. During this time, three patients did not suffer from a new fall. An arrhythmogenic diagnosis was obtained in 5 patients: bradycardia was identified in 4 cases, and tachycardia in one of them. The symptoms did not coincide with a documented arrhythmia in the rest of the patients.

Conclusion

ILR is a helpful tool to establish an arrhythmogenic cause of unexplained and recurrent falls, in this selected sample of older adults.     

Déficit de vitamina D en una cohorte de mayores de 65 años: prevalencia y asociación con factores sociodemográficos y de salud

Introduction

Vitamin D deficiency is common in the elderly, especially among institutionalized and/or hip fracture patients. However, there are few population studies on the prevalence of this deficiency in the general population over 64 years in our environment. The aim of this study was to determine the prevalence of vitamin D deficiency in an urban population cohort of over 64 years, and analyze its relationship with sociodemographic, climatic, and health factors.

Material and methods

Cross-sectional study from «Peñagrande cohort», a population-based cohort consisting of people over 64 years. We determined 25-hydroxyvitamin D levels, and recorded sociodemographic data (age, sex, marital status, education, socioeconomic status), season of measurement and health variables (comorbidity, obesity, malnutrition, renal failure, cognitive impairment, vitamin D supplements, and disability).

Results

A total of 468 individuals with a mean age of 76.0 years (SD: 7.7) were included, of which 53.4% were women. The mean value of vitamin D was 20.3 ± 11.7 ng/mL. The large majority (86.3%, 95% CI: 83.0-89.5) had a vitamin insufficiency (≤ 30 ng/ml), and 35.2% (95% CI: 30.8-39.7) showed severe vitamin deficiency (≤ 15 ng/ml). Vitamin insufficiency increases linearly with age (OR 1.06; 95% CI: 1.01-1.11), and was associated with low socioeconomic status (OR 3.29; 95% CI: 1.55-6.95). Severe vitamin D deficiency increases with age (OR 1.06; 95% CI: 1.02-1.09), female gender (OR 1.80; 95% CI: 1.18-2.75) and with cognitive impairment (OR 1.71; 95% CI: 1.04-2.83).

Conclusion

The prevalence of vitamin D deficiency in people over 65 years of age in our community is high. It would be advisable to determine the vitamin D values in the high risk elderly in order to introduce measures of pharmacological supplementation in those with inadequate levels.
