[ES]El objetivo fue comprobar en la bibliografía el tratamiento de la osteoporosis de carácter preventivo y relacionado con la fisioterapia. Se realizó una búsqueda bibliográfica de publicaciones de los últimos 5 años y se seleccionaron 44 estudios para este trabajo. Se concluye que en diferentes tipos de situación como la postmenopáusica se desconoce su circuito de atención primaria. A través de este ejemplo se puede sustraer información relacionada con esta necesidad en la patología mencionada para las poblaciones con riesgo de fractura y poblaciones sin riesgo de fractura (aparentemente). En las guías de práctica clínica nacionales revisadas, no se explicita el algoritmo de actuación que ha de seguirse ante un paciente con fractura osteoporótica en el ámbito hospitalario.

Introducción: La adherencia al tratamiento oral del paciente con osteoporosis es baja, con un alto porcentaje de abandonos durante el primer año. La consecuencia más notable es la falta de respuesta terapéutica. Objetivo: Conocer la percepción de los facultativos involucrados en el abordaje del paciente osteoporótico en relación a la adherencia terapéutica de estos pacientes. Material y métodos: Estudio descriptivo transversal realizado mediante una encuesta de opinión dirigida a médicos de Atención Primaria y Atención Especializada involucrados en el tratamiento de la osteoporosis. Los participantes fueron seleccionados mediante muestreo intencionado. Resultados: El cuestionario fue contestado por 235 especialistas de Reumatología (54,5%), Traumatología (10,6%) y Atención Primaria (18,7%). En opinión del 43,8% de los encuentados, más de un 25% de los pacientes olvida alguna vez tomar el tratamiento. Según el 34,9%, más de 75% de los pacientes están concienciados con el tratamiento. Los efectos secundarios y la complejidad de la administración son las razones mayoritarias que propician un cambio de medicación, con una importancia media de 7,94±2,06 y 6±2,01 puntos respectivamente en una escala 0-10. Conclusiones: Los facultativos percibieron baja adherencia terapéutica asociada fundamentalmente a los efectos secundarios, a la polimedicación y a la falta de comunicación entre profesionales. Espaciar la dosificación y el uso de formas galénicas solubles podrían ser opciones para facilitar la adherencia del paciente al tratamiento con bisfosfonatos orales. Mejorar la educación sobre la importancia de la enfermedad o aumentar el seguimiento del paciente serían algunos de los aspectos que podrían favorecer la adherencia terapéutica.

Justificación: La osteoporosis es causa de fracturas patológicas y pérdida de autonomía y validismo en la mujer post-menopáusica. La identificación de factores de riesgo puede servir en la prevención de la aparición de esta co-morbilidad. Objetivos: Determinar la asociación entre la desmineralización ósea y características demográficas, clínicas y antropométricas selectas de la mujer post-menopásica que puedan asumirse como factores de riesgo. Diseño del estudio: No experimental, transversal, analítico. Serie de estudio: 53 mujeres con edades ≥ 60 años atendidas en el Hospital "San Juan" de Especialidades de Riobamba (Provincia del Chimborazo, República del Ecuador). Material y método: Se determinó la densidad mineral ósea (DMO) en 2 regiones de interés (columna lumbar I fémur) mediante DEXA (DPX-L, Lunar Technologies, EEUU). La desmineralización ósea se estableció ante puntajes "t" < -1,0 desviaciones estándar. La cuantía y calidad de los ingresos de Calcio dietético se estimaron mediante el puntaje pCa que tiene en cuenta la frecuencia de consumo de alimentos tenidos como fuente de calcio y la biodisponibilidad del mineral. Se evaluaron la naturaleza y la fuerza de la asociación entre la desmineralización ósea, por un lado, y los factores presuntivos de riesgo de osteoporosis y el estado del ingreso del calcio dietético, por el otro. Resultados: La desmineralización ósea fue dependiente de la región de interés: Fémur: Osteoporosis: 13,2% + Osteopenia: 50,9%; Columna lumbar: Osteoporosis: 49,1% + Osteopenia: 37,7%. Los mayores ingresos de calcio dietético se concentraron en: Leche y lácteos (pCa = 26,56), Carnes, pescados, mariscos y huevos (pCa = 6,51), Frijoles y otras leguminosas (soja incluida) (pCa = 2,85); y Verduras (pCa = 2,54); respectivamente. El puntaje "t" de DMO se asoció con la edad de la mujer, los antecedentes familiares de fracturas óseas, el Índice de Masa Corporal (IMC), y la grasa corporal (estimada mediante DEXA). Los ingresos de calcio dietético fueron independientes de los factores presuntivos de riesgo de desmineralización ósea, y del puntaje "t" de DMO en las regiones de interés. Las razones de disparidades para las variables asociadas univariadamente con la DMO fueron como sigue: Edad: OR = 2,09 (p < 0,05); IMC: OR = 0,278 (p = 0,059): y Grasa corporal: OR = 0,553 (p > 0,05); respectivamente. Conclusiones: La desmineralización ósea se asocia significativamente con el envejecimiento femenino, y una mayor presencia de la grasa corporal. Los antecedentes familiares de fracturas óseas pueden servir para identificar a la mujer post-menopáusica con un riesgo incrementado de desmineralización ósea. Se deben emprender investigaciones ulteriores para establecer el papel del ejercicio físico y mejores ingresos de calcio dietético como factores protectores de la pérdida de la DMO.

El calcio es el mineral que más abunda en el cuerpo humano y se necesita en cantidades importantes ya que tiene muchas propiedades, siendo más conocido por nutrir los huesos. Objetivo: conocer y establecer la ingesta de calcio en mujeres posmenopáusicas con osteoporosis que acudan a los hospitales Vicente Corral y José Carrasco de la ciudad de Cuenca. Materiales y Métodos: se realizó un estudio de tipo descriptivo. La muestra correspondió a 108 mujeres posmenopáusicas con osteoporosis que acudieron a los hospitales Vicente Corral y José Carrasco . Se evaluó la ingesta de calcio en los alimentos consumidos diariamente por cada paciente mediante una encuesta de recordatorio de 24 horas validada durante 3 días; previamente se determinó la osteoporosis en las pacientes postmenopáusicas a través de una densitometría axial y femoral. Para el análisis estadístico se utilizó el programa FP2 y el software SPS y se describieron medidas de tendencia central, diferencias de medias, porcentajes. Resultados: 97.32% de mujeres posmenopáusicas con osteoporosis presentaron una deficiente ingesta de calcio. El promedio de calcio ingerido fue 530.18 mg/día, cifra menor a lo recomendado por la OMS, mientras que el 1.79% de las personas encuestadas ingerían calcio en cantidades normales y el 0.89 % de las personas presentaron un consumo alto. El 65.18% perteneció a una condición socioeconómica media alta y 46.43% presentó un estado nutricional adecuado. Conclusión: En el presente estudio existió un predominio de mujeres Posmenopausicas con osteoporosis con ingesta inferior a 1200mg/día de calcio en pacientes que acuden a la consulta de los hospitales Vicente Corral y José Carrasco .

Purpose: To investigate the therapeutic effect of Rhizoma drynariae extract (RDE) on ovariectomyinduced osteoporosis in rats. Methods: Female Sprague-Dawley rats were randomly assigned to a sham-operated group (control) and five ovariectomy (OVX) subgroups: OVX with vehicle (OVX), OVX with 17ß-estradiol (E2, 25 μg/kg/day), and OVX with RDE doses (40, 80, and 160 mg/kg/day). Daily oral administration of E2 or RDE started 4 weeks after OVX and lasted for 16 weeks. The bone mineral density (BMD) of the L4 vertebrae and right femurs was estimated. The length of each femur was measured with a micrometer gauge, and the center of the diaphysis determined. Three representatives L4 vertebrae were selected to evaluate the trabecular microarchitecture. Serum alkaline phosphatase (ALP), urinary calcium (U-Ca), urinary phosphorus (U-P), urinary creatinine (Cr) and osteocalcin (OC) levels were measured. Results: The study showed that high-dose of RDE significantly inhibited the bone mineral density (BMD) reduction of L4 vertebrae (0.20 ± 0.02 g/cm3, p < 0.05) and femurs (0.18 ± 0.02 g/cm3, p < 0.05) caused by OVX and prevented the deterioration of trabecular microarchitecture (p < 0.05), which were accompanied by a significant decrease in skeletal remodeling (p < 0.05) as evidenced by the lower levels of bone turnover markers. High-dose of RDE improved morphometric parameters, namely, Tb-N (3.8 ± 0.2 mm, p < 0.05), Tb-Th (0.083 ± 0.011 mm, p < 0.05) and Tb-Sp (0.19 ± 0.01 mm, p < 0.05) in L4 vertebrae significantly. The present study indicates that the administration of RDE at higher doses over a 16-week period can prevent OVX-induced osteoporosis in rats without hyperplastic effects on the uterus. Conclusion: Thus, RDE is a potential natural alternative for postmenopausal osteoporosis treatment in elderly women.

Purpose: To investigate the anti-osteoporosis effect of Astragalus membranaceus (Fisch.) Bunge. extract (AMBE) in experimental rats. Method: Female Sprague-Dawley rats were randomly divided into six groups: control group, ovariectomy (OVX) with vehicle group, OVX with 17β-estradiol (E2, 25 μg/kg/day) group, and OVX with AMBE doses (60, 120 and 240 mg/kg/day) groups. Daily oral administration of AMBE or E2 was started 4 weeks after OVX and lasted for 16 weeks. The bone mineral density (BMD) of L4 vertebrae and right femurs was evaluated. The length of each femur was measured with a micrometer, and the center of diaphysis was determined. Three representative L4 vertebrae were selected to evaluate trabecular microarchitecture. Serum alkaline phosphatase (ALP), urinary calcium (U-Ca), urinary phosphorus (UP), urinary creatinine (Cr) and osteocalcin (OC) levels were measured. Results: AMBE dose-dependently inhibited the bone mineral density (BMD) reduction of L4 vertebrae (0.27 ± 0.03 g/cm2, p < 0.05) and femurs (0.23 ± 0.03 g/cm2, p < 0.05) caused by OVX and prevented the deterioration of trabecular microarchitecture (p < 0.05), which were accompanied by a significant decrease in skeletal remodeling (p < 0.05) as evidenced by the lower levels of bone turnover markers. A higher dosage of AMBE treatment (240 mg/kg/day) increased U-Ca/Cr (0.27 ± 0.03 mmol/mmol), ALP (137.23 ± 16.72 U/L), U-P/Cr (4.18 ± 0.27 mmol/mmol) and OC (8.47 ± 0.26 mmol/L) levels (both p < 0.05). Conclusion: The findings of this study indicate that AMBE prevents OVX-induced osteoporosis in rats.

Purpose: To investigate the therapeutic effects of Cistanche deserticola Ma. extract (CDME) on ovariectomy-induced osteoporosis in rats. Methods: Female Sprague-Dawley rats were randomly assigned to a control group and five ovariectomy (OVX) subgroups, that is, OVX with vehicle (OVX), OVX with 17ß-estradiol (E2, 25 μg/kg/day), and OVX with CDME doses (40, 80, or 160 mg/kg/day). Daily oral administration of E2 or CDME started 4 weeks after OVX and lasted for 16 weeks. Bone mineral density (BMD) of L4 vertebrae and right femur of rats was estimated, The length of each femur was measured, and biochemical analysis of serum and urine specimens were performed. Results: CDME dose-dependently inhibited the reduction in BMD of L4 vertebrae (0.23 ± 0.02 g/cm3, p < 0.05) and femurs (0.20 ± 0.03 g/cm3, p < 0.05) caused by OVX and prevented the deterioration of trabecular microarchitecture (p < 0.05), which were accompanied by a significant decrease in skeletal remodeling (p < 0.05) as evidenced by the lower levels of bone turnover markers. Conclusion: This study indicates that CDME prevents OVX-induced osteoporosis in rats, and could be used for treating osteoporosis in elderly women.

Objective: To assess the effectiveness of 12 weekly physical therapy sessions for urinary incontinence (UI) compared with a control intervention, for reducing the number of UI episodes measured with the 7-day bladder diary, at 3 months and 1 year postrandomization. Methods: A single parallel-group randomized controlled trial was conducted at one outpatient public health center, in postmenopausal women aged 55 years and over with osteoporosis or low bone density and UI. Women were randomized to physical therapy (PT) for UI or osteoporosis education. The primary outcome measure was number of leakage episodes on the 7-day bladder diary, assessed at baseline, after treatment and at 1 year. The secondary outcome measures included the pad test and disease-specific quality of life and self-efficacy questionnaires assessed at the same timepoints. Results: Forty-eight women participated (24 per group). Two participants dropped out of each group and one participant was deceased before 3-month follow-up. Intention-to-treat analysis was undertaken. At 3 months and 1 year, there was a statistically significant difference in the number of leakage episodes on the 7-day bladder diary (3 mo: P = 0.04; 1 y: P = 0.01) in favor of the PT group. The effect size was 0.34 at 1 year. There were no harms reported. Conclusions: After a 12-week course of PT once per week for UI, PT group participants had a 75% reduction in weekly median number of leakage episodes, whereas the control group's condition had no improvement. At 1 year, the PT group participants maintained this improvement, whereas the control group's incontinence worsened.

Bisphosphonates (BPs) are a class of drugs used to treat osteoporosis and malignant bone metastasis. BPs show high binding capacity to the bone matrix, especially in sites of active bone metabolism. The American Society for Bone and Mineral Research defines BRONJ as an area of exposed bone in the maxillofacial region that has not healed within 8 weeks after identification by a healthcare provider in a patient who is receiving or has been exposed to a bisphosphonate and has not had radiation therapy to the craniofacial region. Bisphosphonate-related osteonecrosis of the jaw (BRONJ) can adversely affect quality of life, as it may produce significant morbidity. The American Association of Oral and Maxillofacial Surgeons (AAOMS) considers as vitally important that information on BRONJ be disseminated to other dental and medical specialties. The purpose of this work is to offer a perspective on how dentists should manage patients on BPs, to show the benefits of accurately diagnosing BRONJ, and to present diagnostic aids and treatments strategies for the condition.

Seizures in some 30% to 40% of patients with epilepsy fail to respond to antiepileptic drugs or other treatments. While much has been made of the risks of new drug therapies, not enough attention has been given to the risks of uncontrolled and progressive epilepsy. This critical review summarizes known risks associated with refractory epilepsy, provides practical clinical recommendations, and indicates areas for future research. Eight international epilepsy experts from Europe, the United States, and South America met on May 4, 2013, to present, review, and discuss relevant concepts, data, and literature on the consequences of refractory epilepsy. While patients with refractory epilepsy represent the minority of the population with epilepsy, they require the overwhelming majority of time, effort, and focus from treating physicians. They also represent the greatest economic and psychosocial burdens. Diagnostic procedures and medical/surgical treatments are not without risks. Overlooked, however, is that these risks are usually smaller than the risks of long-term, uncontrolled seizures. Refractory epilepsy may be progressive, carrying risks of structural damage to the brain and nervous system, comorbidities (osteoporosis, fractures), and increased mortality (from suicide, accidents, sudden unexpected death in epilepsy, pneumonia, vascular disease), as well as psychological (depression, anxiety), educational, social (stigma, driving), and vocational consequences. Adding to this burden is neuropsychiatric impairment caused by underlying epileptogenic processes (essential comorbidities), which appears to be independent of the effects of ongoing seizures themselves. Tolerating persistent seizures or chronic medicinal adverse effects has risks and consequences that often outweigh risks of seemingly more aggressive treatments. Future research should focus not only on controlling seizures but also on preventing these consequences.

Obesity is currently considered a major public health problem in the world, already reaching epidemic characteristics, according to the World Health Organization. Excess weight is the major risk factor associated with various diseases, such as type 2 diabetes mellitus, hypertension, dyslipidemia and osteometabolic diseases, including osteoporosis and osteoarthritis. Osteoarthritis is the most prevalent rheumatic disease and the leading cause of physical disability and reduced quality of life of the population over 65 years. It mainly involves the joints that bear weight - knees and hips. However, along with the cases of obesity, its prevalence is increasing, and even in other joints, such as hands. Thus, it is assumed that the influence of obesity on the development of OA is beyond mechanical overload. The purpose of this review was to correlate the possible mechanisms underlying the genesis and development of these two diseases. Increased fat mass is directly proportional to excessive consumption of saturated fatty acids, responsible for systemic low-grade inflammation condition and insulin and leptin resistance. At high levels, leptin assumes inflammatory characteristics and acts in the articular cartilage, triggering the inflammatory process and changing homeostasis this tissue with consequent degeneration. We conclude that obesity is a risk factor for osteoarthritis and that physical activity and changes in diet composition can reverse the inflammatory and leptin resistance, reducing progression or preventing the onset of osteoarthritis.

The aim of the present study was to identify factors associated with the occurrence of falls among elderly adults in a population-based study (ISACamp 2008). A population-based cross-sectional study was carried out with two-stage cluster sampling. The sample was composed of 1,520 elderly adults living in the urban area of the city of Campinas, São Paulo, Brazil. The occurrence of falls was analyzed based on reports of the main accident occurred in the previous 12 months. Data on socioeconomic/demographic factors and adverse health conditions were tested for possible associations with the outcome. Prevalence ratios (PR) were estimated and adjusted for gender and age using the Poisson multiple regression analysis. Falls were more frequent, after adjustment for gender and age, among female elderly participants (PR = 2.39; 95% confidence interval (95% CI) 1.47 - 3.87), elderly adults (80 years old and older) (PR = 2.50; 95% CI 1.61 - 3.88), widowed (PR = 1.74; 95% CI 1.04 - 2.89) and among elderly adults who had rheumatism/arthritis/arthrosis (PR = 1.58; 95% CI 1.00 - 2.48), osteoporosis (PR = 1.71; 95% CI 1.18 - 2.49), asthma/bronchitis/emphysema (PR = 1,73; 95% CI 1.09 - 2.74), headache (PR = 1.59; 95% CI 1.07 - 2.38), mental common disorder (PR = 1.72; 95% CI 1.12 - 2.64), dizziness (PR = 2.82; 95% CI 1.98 - 4.02), insomnia (PR = 1.75; 95% CI 1.16 - 2.65), use of multiple medications (five or more) (PR = 2.50; 95% CI 1.12 - 5.56) and use of cane/walker (PR = 2.16; 95% CI 1.19 - 3,93). The present study shows segments of the elderly population who are more prone to falls through the identification of factors associated with this outcome. The findings can contribute to the planning of public health policies and programs addressed to the prevention of falls.
