Fracturas de la tibia proximal como complicación de la osteotomía tibial proximal valguizante.

Hemos realizado un estudio retrospectivo de 12 osteotomías valguizantes de tibia proximal en las que ocurrió fractura del fragmento proximal, de un total de 409 osteotomías realizadas en nuestro hospital para el tratamiento de la gonartrosis del compartimento medial. La fractura tuvo lugar en la meseta interna en 9 de ellas, en la eminencia intercondílea en 2 y en ambas mesetas tibiales en el caso restante. El mecanismo de producción fue el cierre de la osteotomía en 8 casos, la extensión de la línea de la osteotomía hacia un defecto en el cóndilo afectado en 2 y un fragmento proximal demasiado fino en otros 2. Todas las fracturas consolidaron en 6 semanas. Los resultados de la revisión fueron buenos en 8 y malos en 4 de ellos.We performed a retrospective study of 12 upper closing wedge valgus tibial osteotomies complicated with fracture of the proximal fragment, out of 409, with medial compartment osteoarthritis of the knee. The fracture occured on the medial condyle only in 8 knees, on the medial and lateral condyles in 1 knee and intercondyloid eminence in 2 knees. The mechanism of production were closing of the osteotomy in 8, osteotomy line extended into a defect of the affected condyle in 2, and a thin proximal fragment in 2. All fractures consolidated in six weeks. The clinical results at follow-up were good in 8 and bad in 4

Impacto del consejo médico para dejar de fumar durante la gestación

ObjetivoEl consumo de tabaco entre las mujeres ha aumentado en España en los últimos años, especialmente entre los grupos en edad reproductiva. El objetivo del estudio es evaluar el impacto del consejo médico integrado en la atención prenatal sobre el consumo de tabaco durante el embarazo y en el posparto.DiseñoEstudio de intervención cuasiexperimental.EmplazamientoHospital del Mar de Barcelona.PacientesEl grupo control estaba constituido por 219 pacientes que acudieron para atención al parto al hospital del Mar en 1996, el grupo de intervención, por 169 pacientes atendidas durante el embarazo en el mismo hospital en 1997.IntervencionesLas pacientes del grupo control habían recibido atención habitual. Las gestantes del grupo de intervención recibieron de forma sistemática un consejo estructurado para dejar de fumar, reforzado por un folleto elaborado con esta finalidad.Mediciones y resultadosLos grupos de intervención y control no presentaban diferencias estadísticamente significativas en las variables sociodemográficas ni en el consumo de tabaco. En ambos grupos se determinó la evolución del hábito tabáquico durante el embarazo a lo largo de las visitas prenatales, y a los 6 meses posparto, a través de una entrevista telefónica. De las gestantes del grupo control, 44 (20,1%) habían dejado de fumar antes de la primera visita prenatal y 11 (5%) lo hicieron durante el embarazo. En el grupo de intervención 26 (17,7%) habían dejado de fumar espontáneamente y 16 (10,9%) dejaron de fumar durante el embarazo. De las que dejaron de fumar completamente durante el embarazo, se mantenían abstinentes a los 6 meses el 36,4% de las mujeres del grupo de control y el 64,3% en el grupo de intervención (p = 0,002).ConclusionesEl consejo para dejar de fumar en la visita prenatal produce un aumento discreto en la proporción de abandonos, y una disminución significativa de las recaídas en el posparto.ObjectiveWomen´s tobacco consumption has increased in Spain in recent years, especially among women of reproductive age. This study aims to evaluate the impact of medical counselling integrated into pre-natal care on tobacco consumption during pregnancy and the period after delivery.DesignQuasi-experimental intervention study.SettingHospital del Mar, Barcelona.Patients219 patients who attended the Hospital del Mar for delivery during 1996 (control group) and 169 patients seen during their pregnancies at the same hospital in 1997 (intervention group).InterventionsThe control group patients had received normal care. The pregnant women in the intervention group received systematic structured counselling on giving up smoking, backed up by a special brochure composed for this purpose.Measurements and resultsThe intervention and control groups showed no statistically significant differences either in their social or demographic variables or in their tobacco consumption. In both groups the evolution of their smoking during pregnancy was determined during their pre-natal visits and six months after delivery through a telephone interview. 44 of the women in the control group (20.1%) gave up smoking before their first pre-natal visit, and 11 (5%) gave up during pregnancy. In the intervention group 26 (17.7%) had given up spontaneously and 16 (10.9%) gave up during pregnancy. Of those who gave up completely during pregnancy, 36.4% of women in the control group and 64.3% in the intervention group remained abstinent at six months (P=.002).ConclusionsCounselling at pre-natal checkups to give up smoking lightly increases the number of women who give up and reduces significantly the number of post-delivery backsliders

Increased circulating adiponectin levels and decreased leptin/soluble leptin receptor ratio throughout puberty in female ballet dancers:association with body composition and delay in puberty

Introduction: Ballet dancers (BDs) have a negative energy balance related to physical training that results in alterations in body composition, sexual development, and adipokine secretion. Our aims were to study anthropometric parameters, body composition, and their relationship with adipokines throughout pubertal development. Subjects and methods: We carried out a prospective follow-up study of 22 female Caucasian BDs (Tanner II stage) followed throughout puberty. Nutritional status was determined by measurement of height, weight, and body mass index (BMI). We calculated growth velocity, bone maturity, and body composition at Tanner stages II, III, and V by dual energy X-ray absorptiometry. Circulating leptin, adiponectin, and soluble leptin receptor (sObR) levels were determined. Results: BDs presented a delay in skeletal maturation during puberty, without affectation of final height. Energy intake was deficient according to their physical exercise, and they had a delay of 1 year in the mean age of menarche. Leptin levels were decreased, whereas sObR and adiponectin levels were increased throughout puberty. The percentage of trunk fat, total fat mass, and fat of the extremities was decreased throughout the study period (P<0.01). Lean mass was increased in the lower extremities, and bone mineral density was normal. Conclusion: A negative energy balance together with maintained physical exercise induced modifications in body composition in BDs. Changes in leptin and adiponectin levels appear to be more related to total fat content than to BMI. Furthermore, the onset and delayed progress of puberty may be related with an inadequate energy balance due to increased exercise

Folding of cytosine-based nucleolipid monolayer by guanine recognition at the air-water interface

Monolayers of a cytosine-based nucleolipid (1,2-dipalmitoyl-sn-glycero-3-(cytidine diphosphate) (ammonium salt), CDP-DG) at basic subphase have been prepared at the air-water interface both in absence and presence of guanine. The formation of the complementary base pairing is demonstrated by combining surface experimental techniques, i.e., surface pressure (π)–area (A), Brewster angle microscopy (BAM), infrared spectroscopy (PM-IRRAS) and computer simulations. A folding of the cytosine-based nucleolipid molecules forming monolayer at the air-water interface occurs during the guanine recognition as absorbate host and is kept during several compression-expansion processes under set experimental conditions. The specificity between nitrogenous bases has been also registered. Finally, mixed monolayers of CDP-DG and a phospholipid (1,2-dimyristoyl-sn-glycero-3-phosphate (sodium salt), DMPA) has been studied and a molecular segregation of the DMPA molecules has been inferred by the additivity rule

Landscape Services versus Ecosystem Services in the Mediterranean: a case study example and an invitation to reflect

Ecosystem Services, defined as the benefits people obtain from ecosystems, are triggering a paradigmatic shift in how we plan and implement decisions on land-use and land-cover change (Albert et al, 2014; Förster et al, 2015). However this concept is being challenged by critiques of scientific, operational and ideological nature (Norgaard, 2010; Hauck et al, 2013; Jax et al, 2013). Some of these critiques point out to the decoupling of the natural and human dimensions of land-use and land-cover that is inherent to Ecosystem Services (Schröter et al, 2014). We consider this to be especially relevant for mixed land-use mosaics in the Mediterranean region, as this is a geographical context where the cultural and perceived components of land-use and land-cover may be considered to equal, if not to prevail, in value and importance on respect to those of ecological nature (Blondel, 2006). In this paper, we argue that Landscape Services may be, in such contexts, a more adequate coneptual tool to disentangle the complex relationships between humans and nature. Landscape Services are defined as the contributions of landscapes and landscape elements to human wellbeing (Bastian et al, 2014). In contrast with ecosystems, landscapes are inarguably coupled social-ecological systems, which also embrace cultural, and perceptual aspects of landuse and land-cover (Pedroli, Pinto-Correia & Cornish, 2006). Furthermore, Landscapes are defined at scales at which coordinated decision-making for land-use change is most commonly apparent (Blaschke, 2006). Thus, we hereby will discuss if in Mediterranean rural contexts Landscape Services should directly substitute Ecosystem Services, and not just, as the aforementioned literature suggests,complement them

Efficacy and efficiency of a new therapeutic approach based on activity-oriented proprioceptive antiedema therapy (TAPA) for edema reduction and improved occupational performance in the rehabilitation of breast cancer-related arm lymphedema in women: a controlled, randomized clinical trial

Background: Breast cancer (BC) is a major public health issue. More than one out of five women treated for breast cancer will develop lymphedema in an upper extremity. Current evidence advocates transdisciplinary oncological rehabilitation. Therefore, research in this area is necessary since limited consensus having been reached with regard to the basic essential components of this rehabilitation. Consensus has, however, been reached on the use of decongestive lymphedema therapy (DLT), but due to a lack of tests, the necessary dosages are unknown and its level is moderately strong. This study attempts to verify both the efficacy of activity-oriented proprioceptive antiedema therapy (TAPA), as compared to conventional treatments such as DLT or Complex Physical Therapy (CPT), as well as its efficiency in terms of cost-effectiveness, for patients affected by breast cancer-related arm lymphedema. Methods: Controlled, randomized clinical trial with dual stratification, two parallel arms, longitudinal and single blind. 64 women with breast cancer-related arm lymphedema will take part in the study. The experimental group intervention will be the same for stage I and II, and will consist of neuro-dynamic exercises oriented to the activity, proprioceptive neuromuscular facilitation activities and proprioceptive anti-edema bandaging. The control group intervention, depending on the stage, will consist of preventive measures, skin care and exercise-prescribed training in the lymphedema workshop as well as compression garments (Stage I) or conservative Complex Decongestive Therapy treatment (skin care, multi-layer bandaging, manual lymphatic drainage and massage therapy) (Stage II). Results: Sociodemographic and clinical variables will be collected for the measurement of edema volume and ADL performance. Statistical analysis will be performed on intent to treat. Discussion: It has been recommended that patient training be added to DLT, as well as a re-designing of patient lifestyles and the promotion of health-related aspects. In addition, clinical trials should be undertaken to assess neural mobilization techniques and proprioceptive neuromuscular facilitation should be included in the therapy. Cohesive bandaging will also be performed as an early form of pressotherapy. The proposed study combines all of these aspects in order to increased comfort and promote the participation of individuals with lymphedema in everyday situations. Limitations: The authors have proposed the assessment of the experimental treatment for stages I and II. One possible limitation is the lack of awareness of whether or not this treatment would be effective for other stages as well as the concern for proper hand cleansing during use of bandages, given the current COVID-19 pandemic situation. Trial registration: This trial was registered in ClinicalTrials.gov (NCT03762044). Date of registration: 23 November 2018. Prospectively Registered
