Incidencia y factores explicativos de las caídas en ancianos que viven en la comunidad

Introductionfalls in the elderly are a significant health problem that can be prevented once risk factors have been identified. The objective of this study was to determine the rate of falls among elderly persons living in the community and their risk factors.Patients and methodstwo hundred ambulatory individuals aged 75 years or older attending an outpatient clinic were evaluated by personal interview. Demographic and social variables, health characteristics, use of healthcare resources and falls were studied. Bivariate analysis was performed and significant variables were entered into a conditional logistic regression analysis.Resultsthe rate of falls per year was 56.5% and rate of recurrent falls was 10.5%. The factors associated with falls in the logistic regression model were living with a spouse (OR = 0.37), taking three or more drugs (OR = 5.30), cardiovascular diseases (OR = 0.29), and taking nitrates (OR = 0.21). The factors associated with recurrent falls were change of home (OR = 11.10), living with a spouse (OR = 0.20), respiratory (OR = 6.44) and cardiovascular diseases (OR = 0.27), and taking laxatives (OR = 9.55).Conclusionsin our study the rate of falls and recurrent falls was similar to that described in other studies in western countries. Our results suggest that taking at least three medications and the use of laxatives were potentially preventable risk factors. Living with a spouse seemed to protect from both falls and recurrent falls in elderly people living in the community.     

Caracterización y costes asociados al perfil del paciente con diabetes tipo 2 en tratamiento con metformina al que se le añade un segundo fármaco antidiabético oral: estudio de base poblacional

ObjectivesTo determine compliance, metabolic control, complications and healthcare costs of patients treated with metformin started a second antidiabetic drug in patients with type 2 diabetes (T2DM).Patients and methodsDesign multicenter observational retrospective. Patients were evaluated ≥30 years (age), treated with metformin and started a second antidiabetic treatment during 2008-2009. There were 4 patient groups (metformin and another antidiabetic): a) dipeptidyl peptidase-4 inhibitors (IDPP4), b) sulfonylureas, c) glitazones and d) insulin. Main measures: comorbidity, metabolic control, compliance and complications. Patients were followed for 2 years. The cost model differed direct health costs (primary care / specialist) and indirect (labor productivity). Statistical analysis: logistic regression models and ANCOVA, p < 0.05.Results2067 patients were included (mean age: 66.6 years male: 53.1%). 25.1% started a second treatment with IDPP4; 42.9% sulfonylureas, 14.0% glitazones and 18.0% insulin. At 2 years follow-up, patients treated with IDPP4 showed greater adherence vs. 70.3%. 59.9%, 60.3% and 58.4; better control of 64.3% vs. DM2. 62.6%, 62.8% and 50.5% and a decrease of 13.9% compared to hypoglycaemia 40.4%, 37.6% and 58.9% respectively (p < 0.001). The average / unit total costs was €2,321 vs. €2,475, €2,724 and €3,164, respectively, p < 0.001. Rates of cardiovascular events and renal failure were 3.7%, 6.4%, 7.6% and 10.2% respectively.ConclusionsSulfonylureas were the most commonly used drugs. Patients treated with IDPP4 had higher compliance and control of diabetes, with lower rates of hypoglycaemia and healthcare costs.     

Weekly iron folic acid supplementation plays differential role in maintaining iron markers level in non-anaemic and anaemic primigravida: A randomized controlled study

Anaemia during pregnancy is most commonly observed and highly prevalent in South-East Asia. Various effective programmes have been laid down for its management, mainly daily supplementation of iron folic acid (IFA) tablets. Following the same, standard obstetrical practice has included the IFA supplementation without requiring the determination of iron deficiency. In this study, a total of 120 primigravida (N = 60; non-anaemic (Hb > 11 g/dl) and N = 60 anaemic (Hb = 8–11 g/dl)) were selected among those attending the Antenatal Clinic in Department of Obstetrics and Gynaecology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, India. They were supplemented with daily and weekly IFA tablets till 6 weeks postpartum. Corresponding changes in haemoglobin level on advance of pregnancy, side effects and compliance associated with daily and weekly IFA supplementation and its associations with iron status markers were studied. The inflammatory markers were also estimated. The statistical significance level (p < 0.05) between the groups were assessed by applying unpaired t-test using SPSS (version 16.0). The obtained results publicized the salutary role of daily IFA supplementation in improving the haemoglobin level and iron status markers in anaemic pregnant women though the levels could not reach up to the non-anaemic haemoglobin levels. However, weekly IFA supplementation seems to be a better approach in non-anaemic pregnant women where almost comparable results were obtained in terms of haematological parameters, gestation length and birth weight.ConclusionWeekly IFA supplementation found to be as effective as daily supplementation in iron sufficient non-anaemic pregnant women whereas anaemic pregnant women should be prescribed daily IFA supplementation irrespective of iron replete/deplete state.     

Sacubitril/Valsartan is useful and safe in elderly people with heart failure and reduced ejection fraction. Data from a real-word cohort

BackgroundHF elderly patients are underrepresented in Sacubitril/Valsartan HF trials, and the effect of S/V in real-life patients with advanced age is unknown. The aim of this study was to evaluate the use and safety of S/V in a real-word cohort of elderly patients.MethodsWe performed a prospective registry of patients who started S/V in clinical practice. We compared baseline characteristics, adverse events during follow-up and causes of S/V withdrawal according to age.ResultsA total of 427 patients started treatment with S/V: 222 (52.0%) < 70 years old, 140 (32.8%) between 70 and 79 and 65 (15.2%) ≥ 80. During a mean follow-up of 7.0 ± 0.1 months S/V was well tolerated, with no age-related differences in adverse events (26.8%, 25.9%, 23.1% respectively; p = 0.83). Symptomatic hypotension tended to be more frequent in the elderly (19.8%, 25.6%, 33.3% respectively; p = 0.17). The withdrawal of S/V was more frequent in younger patients (14.4%, 10.0%, 4.6% respectively; p = 0.05) and related to poor prognosis (HR 13.51, 95% CI 3.22–56.13, p < 0.001).ConclusionsSacubitril/Valsartan is useful and safe in elderly people with HF-rEF in real-life clinical practice, and withdrawal is associated to poor prognosis. The doses achieved are lower in elderly people.     

Hierro intravenoso,recuperación funcional y delirium en pacientes con fractura de cadera. Estudio FEDEREF. Ensayo clínico unicéntrico aleatorizado,controlado con placebo,doble ciego. Número EudraCT: 2014-001923-53

Introduction

There are no previous studies evaluating the effect of intravenous iron therapy on functional and cognitive status of patients with hip fracture (HF).

Estimación del filtrado glomerular en el paciente anciano. Implicaciones clínicas en el uso de antibióticos

IntroductionIn elderly, impaired kidney function may lead to relevant clinical implications, especially in drug dosage. There is no consensus on the best formula to estimate glomerular filtration rate (GFR) in this context. While the Cockcroft–Gault (CG) equation is the most used one in drug development, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation is the most employed by clinical laboratories. The objective of this study is to analyze the differences and implications of using one or another equation when adjusting the dose of antibiotics.Material and methodsCross-sectional study performed in patients older than 80 years admitted to an acute geriatric unit for infectious disease. Socio-demographic, functional, clinic, assistance and laboratory variables were gathered, calculating GFR according to CG and CKD-EPI. A concordance study between both equations, bivariate analysis and multiple linear regression were carried out.Results100 patients were recruited, with mean age 88.5 ± 4.2 years, and 54% women. A relative overestimation of 13.63 mL/min was observed in GFR according to CKD-EPI, with a low-moderate concordance between both formulas. Greater need for dose adjustment of antibiotics with GC than with CKD-EPI was detected (38% vs. 23%; P < .001), as well as dosage discrepancies, especially with levofloxacin.ConclusionsBoth equations are not interchangeable in the elderly. When used to adjust antibiotic dose, CKD-EPI may overestimate GFR and may cause an increase in adverse reactions. Further studies should be carried out with the aim of reaching a consensus on the most appropriate equation for the elderly patient.     

Innovando en la toma de decisiones compartida con pacientes hospitalizados: descripción y evaluación de una herramienta de registro de nivel de intensidad terapéutica

Background and aimShared decision-making between patients and healthcare professionals is crucial to guarantee adequate coherence between patient values and preferences, caring aims and treatment intensity, which is key for the provision of patient-centred healthcare. The assessment of such interventions are essential for caring continuity purposes. To do this, reliable and easy-to-use assessment systems are required. This study describes the results of the implementation of a hospital treatment intensity assessment tool.Material and methodsThe pre-implementation and post-implementation results were compared between two cohorts of patients assessed for one month.ResultsSome record of care was registered in 6.1% of patients in the pre-implementation group (n = 673) compared to 31.6% of patients in the post-implementation group (n = 832) (P < .01), with differences between services. Hospital mortality in both cohorts is 1.9%; in the pre-implementation group, 93.75% of deceased patients had treatment intensity assessment.ConclusionsIn hospital settings, the availability of a specific tool seems to encourage very significantly shared decision-making processes between patients and healthcare professionals —multiplying by more than 5 times the treatment intensity assessment. Moreover, such tools help in the caring continuity processes between different teams and the personalisation of caring interventions to be monitored. More research is needed to continue improving shared decision-making for hospital patients     

Antihypertensive medications and survival in patients with cancer: A population-based retrospective cohort study

Background: The association between antihypertensive medications and survival in cancer patients remains unclear. Objectives: To explore the association between classes of antihypertensive drugs and survival in cancer patients. Methods: Provincial Cancer Registry data was linked with a Provincial Drug Program Information Network (DPIN) for patients with lung (n = 4241), colorectal (n = 3967), breast (n = 4019) or prostate (n = 3355) cancer between the years of 2004 and 2008. Cox regression analyses were used to compare survival of patients using beta blockers (BBs), angiotensin-converting enzyme inhibitors/receptor blockers (ACEi/ARB), calcium channel blockers (CCBs) or thiazide diuretics (TDs) to survival of patients who did not use any of these antihypertensive drugs. Survival of patients using only one class of antihypertensive drugs were compared to each other, with BBs as the reference class. Results: Compared to the antihypertensive drug non-user cohort, BBs had no effect on survival for any of the cancers. ACEi/ARBs use was weakly associated with increased deaths for breast cancer (HR: 1.22, 95% CI: 1.04–1.44) and lung cancer (HR: 1.11, 95% CI: 1.03–1.21) patients. Deaths were also increased with CCB use in patients with breast cancer (HR: 1.22, 95% CI: 1.02–1.47) and with TD use in lung cancer patients (HR: 1.1, 95% CI: 1.01–1.19). There was strong evidence (p-value <0.0001) of an increase in deaths with TD use for colorectal (HR: 1.28, 95% CI: 1.15–1.42), and prostate (HR 1.41, 1.2–1.65) cancer patients. When including only antihypertensive drug users prescribed one drug class, lung cancer patients receiving CCBs had improved survival compared to BBs (HR 0.79, 95% CI: 0.64–0.98). Conclusions: Some classes of antihypertensive agents are associated with a decreased survival in certain cancers. The decrease could be due to more comorbidities in antihypertensive drug users. However, CCB use was associated with improved survival in lung cancer patients.     

Effect of phytic acid,tannic acid and pectin on fasting iron bioavailability both in the presence and absence of calcium

ObjectiveTo determine the effect of phytic acid, tannic acid and pectin on fasting non-heme iron bioavailability in both the presence and absence of calcium.Research methodsTwenty-eight apparently healthy adult females participated in two iron absorption studies using radioactive iron isotopes (⁵⁹Fe and ⁵⁵Fe). One group received 5 mg of iron (as FeSO₄) alone (control), together with 10 mg of phytic acid, 100 mg of tannic acid and 250 mg of pectin (study A), on different days. The second group received the same iron doses and compounds as the other group, plus 800 mg of calcium (CaCl₂) (study B). The compounds were administered after an overnight fast, and no food or beverages were consumed for the following 3 h. Iron status and circulating radioactivity were measured in venous blood samples.ResultsThe geometric means of iron bioavailability (range ± 1SD) for iron alone, iron with phytic acid, iron with tannic acid, and iron with citrus pectin were 25.0% (11.9–52.0); 18.9% (9.9–35.8); 16.8% (8.7–32.3); and 21.1% (10.2–43.9), respectively (repeated-measures ANOVA, p < 0.02 (Dunnett's post hoc: control vs tannic acid p < 0.05). When 800 mg of calcium was added (study B), iron bioavailability was 16.7% (10.1–27.5); 13.2% (7.1–24.6); 14.8% (8.8–25.1); and 12.6% (5.5–28.8), respectively (repeated-measures ANOVA, NS).ConclusionsTannic acid decreases the fasting bioavailability of non-heme iron, however this effect did not exist in the presence of calcium. No effect was observed by phytic acid or citrus pectin on fasting non-heme iron bioavailability in both the presence and absence of calcium.     

Tendencias en las hospitalizaciones psiquiátricas de personas mayores de 65 años

BackgroundThe aim of this study was to analyse the trend in the percentages of elderly patients admitted to hospital for psychiatric reasons. An additional aim was to analyse the characteristics of the elderly population admitted to a psychiatric hospitalisation unit.Material an MethodsAn analysis was made of the trends in the percentages of discharges in elderly population at the national level and in the Mental Health Hospitalisation Unit (MHHU) of the Regional University Hospital of Malaga for a period of at least 18 years using segmented regression. For the study of the characteristics of the elderly population, all patients (N = 5,925) and consecutive episodes of admission (N = 15,418) were compared between 1999 and 2017 in the MHHU.ResultsAt the national level, there was an increase in hospital discharges in elderly patients with a significant mean annual percent change of 2.0%. In the study unit, the elderly population were more frequently female, involuntarily admitted, and had a longer hospital stay. They had been diagnosed more frequently with organic and depressive mental disorders, and less frequently with schizophrenia, substance use, and personality disorders.ConclusionsThere was a growing trend in the percentage of elderly psychiatric patients admitted to hospitals during the study period. These results point to the increase in elderly psychiatric admissions and thus the need to adapt psychiatric units to the characteristics of this population.     

Flexibilidad psicológica,burnout y satisfacción vital en profesionales que trabajan con personas afectadas de demencia

IntroductionThe clinical complexity of dementia, its physical burden, and the potential assaults associated with psychological and behavioral symptoms, could put healthcare workers working with dementia at high risk of burnout. Certain attitudes toward dementia and certain coping styles may be a protective factor against the stress experienced by these workers. On the other hand, it has been shown that a coping style based on psychological flexibility can prevent the development of burnout in the workplace. The present study analyzes the relationship between levels of burnout, psychological flexibility, attitudes towards dementia and life satisfaction in a sample of healthcare workers who work with people affected by dementia.MethodsA sample of 105 healthcare workers from the Ricard Fortuny Social Hospital was recruited (day hospital, hospitalization unit, and nursing home), and psychological flexibility (AAQII), burnout levels (MBI), life satisfaction (SWL), anxiety (STAI-R), and attitudes towards dementia (EAD) were assessed.ResultsPsychological inflexiblility showed a positive relationship with 2 dimensions of burnout (emotional exhaustion [r = .342, P < .01]; depersonalization [r = .328, P < .01]), and with anxiety (r = .723, P < .01), and also showed a negative relation with life satisfaction (r = ?.485, P < .01) and affect attitude (r = ?.209); p < .05). It was also found a negative relation between rejection attitude with emotional exhaustion (r = ?.328, P < .01) and with depersonalization (r = ?.328; P < .01).ConclusionsThose participants with greater psychological flexibility, in addition to feel more satisfaction with life, were found to be less likely to feel emotionally exhausted, to depersonalize patients with dementia, and felt more affection for them. On the other hand, no relationship was found between Burnout levels and the cognitive dimension of Attitudes towards dementia (the worker's knowledge of dementia). The results have significant implications regarding the type of training that is given to healthcare workers who work with people affected by dementia. Psychoeducational interventions promoting the psychological flexibility could help to reduce the risk of burnout in healthcare workers who work with dementia.     

Development of an LC-MS/MS method for the quantitation of 55 compounds prescribed in combined cardiovascular therapy

This paper reports an LC–MS/MS method with positive electrospray ionization for the screening of commonly prescribed cardiovascular drugs in human plasma, including compounds with antihypertensive (57), antidiabetic (12), hypolipemiant (5), anticoagulant (2) and platelet anti-aggregation (2) effects. Sample treatment consisted of a simple protein precipitation with MeOH/0.1 M ZnSO₄ (4:1, v/v) solution after the addition of internal standard, followed by evaporation and reconstitution. Analytes separation was performed on a Polar-RP column (150 mm × 2 mm, 4 μm) using a gradient elution of 15 min. The MS system was operated in MRM mode, monitoring one quantitation and one confirmation transition for each analyte. The recovery of the protein precipitation step ranged from 50 to 70% for most of the compounds, while some were considerably affected by matrix effects. Since several analytes fulfilled the linearity, accuracy and precision values required by the ICH guidelines, the method proved to be suitable for their quantitative analysis. The limits of quantitation varied from 0.38 to 9.1 μg/L and the limits of detection from 0.12 to 5.34 μg/L. The method showed to be suitable for the detection of plasma samples of patients under cardiovascular treatment with the studied drugs, and for 55 compounds reliable quantitative results could be obtained.     

Iron levels in the human brain: A post-mortem study of anatomical region differences and age-related changes

The link between brain iron homeostasis and neurodegenerative disease has been the subject of extensive research. There is increasing evidence of iron accumulation during ageing, and altered iron levels in some specific brain regions in neurodegenerative disease patients have been reported.Using graphite furnace atomic absorption spectrometry after microwave-assisted acid digestion of the samples, iron levels were determined in 14 different areas of the human brain [frontal cortex, superior and middle temporal, caudate nucleus, putamen, globus pallidus, cingulated gyrus, hippocampus, inferior parietal lobule, visual cortex of the occipital lobe, midbrain, pons (locus coeruleus), medulla and cerebellum (dentate nucleus)] of n = 42 adult individuals (71 ± 12 years old, range: 53–101 years old) with no known history or evidence of neurodegenerative, neurological or psychiatric disorders.It was found that the iron distribution in the adult human brain is quite heterogeneous. The highest levels were found in the putamen (mean ± SD, range: 855 ± 295 μg/g, 304–1628 μg/g) and globus pallidus (739 ± 390 μg/g, 225–1870 μg/g), and the lowest levels were observed in the pons (98 ± 43 μg/g, 11–253 μg/g) and medulla (56 ± 25 μg/g, 13–115 μg/g).Globally, iron levels proved to be age-related. The positive correlation between iron levels and age was most significant in the basal ganglia (caudate nucleus, putamen and globus pallidus).Compared with the age-matched control group, altered iron levels were observed in specific brain areas of one Parkinson's disease patient (the basal ganglia) and two Alzheimer's disease patients (the hippocampus).     

Análisis longitudinal de parámetros nutricionales en una cohorte de ancianos con y sin demencia

IntroductionIt is important to assess longitudinal nutritional parameters during the ageing process in order to determine body composition changes. This procedure is more relevant when dealing with institutionalised geriatric patients suffering from cognitive impairment. The aim of this study was to assess the interactions, if any, between mental status and several nutritional parameters in a cohort of elderly people.Material and methodsA longitudinal prospective two years follow-up evaluation was performed on 301 elderly residents (233 females and 68 males) in a nursing home, of whom 51 of them fulfilled the clinical criteria for dementia. Both anthropometric and biochemical parameters were obtained annually, according to standard procedures.ResultsThe dementia group had lower values when compared to the non-dementia group. Furthermore, nutritional values remained constant in the group with cognitive impairment (no significant differences were observed throughout the study period). BMI 24.5 ± 4.9 vs 24.2 ± 4.1; tricipital skinfold 15.0 ± 6.0 vs 14.7 ± 6.9; brachial circumference 25.9 ± 3.3 vs 25.7 ± 3.5, and albumin 3.7 ± 0.3 vs 3.7 ± 0.3. At the end of the study, the group without cognitive impairment showed lower values in all the parameters analysed when compared to the baseline ones, except for bicipital fold and plasma triglycerides.ConclusionsOur study shows that there are no variations in the elderly with cognitive impairment, as regards the nutritional, anthropometric and biochemist parameters analysed. On the contrary, the group with normal cognitive status showed a reduction in most of the parameters. Further studies analysing larger populations of elderly people and over longer periods of time will provide more information to improve our knowledge on this important issue.     

Detección y seguimiento de malos tratos en personas mayores en un hospital terciario: experiencia de 3 años

Objectives

The Hospital Clínico San Carlos Committee against violence established a protocol in 2012 in order to detect and follow-up violence against elderly persons. This article presents the experience after 3 years of its introduction, as well as an analysis comparing the differences between those younger and older than 65 years of age.
