Evolución de la flexibilidad de la cadena cinética posterior en escolares de 5 a 11 años

La finalitat del nostre estudi és valorar l’evolució de la flexibilitat de la cadena cinètica posterior en els escolars de 5 a 11 anys, i observar en quins grups d’edat és necessària l’aplicació de programes específics per a millorar-la. Els escolars varen ser sotmesos a les mateixes valoracions: el test de “sit and reach”, la pressa de les mesures antropomètriques, altura i pes, i el qüestionari Minesotta sobre el consum calòric en el temps de lleure. Dels resultats es desprèn que a mesura que augmenta l’edat, la flexibilitat dels escolars estudiats disminueix progressivament. Existeix un interval d’edat situat en els 9 anys que sembla marcar un canvi de tendència en la flexibilitat dels escolars. És a partir d’aquesta edat quan el grau de flexibilitat disminueix de forma significativa i, es més marcada entre els nens, sent necessària una intervenció més específica en ells

Programa de intervención específico para la mejora de la flexibilidad en escolares: es efectiva la intervención del MEF?

La finalitat del nostre va ser valorar l’aplicació d’un programa d’intervenció específic per a millorar la flexibilitat en un grup d’escolars de 9 anys. Van ser inclosos en l’estudi 63 escolars de 4º curs d’Educació Primària, del Centre Escolar la Salle i el CEIP St. Ignasi, ambdós de Manresa (Barcelona). Durant tres setmanes, el centre La Salle va aplicà un programa específic per a millorar la flexibilitat de la cadena cinètica posterior. En canvi, el CEIP St. Ignasi es va utilitzar com a grup control, continuant el seu programa educatiu habitual. Hem observat que l’aplicació de programes específics per a millorar la flexibilitat és efectiva en los escolares de 9 anys. La forma de aplicar els programes de educació física modifica significativament el grau de flexibilitat en los escolares

Fuerza prensil de la mano asociada al grado de autonomía y riesgo de caída en ancianos

Objetivo: Determinación de la fuerza de prensión de la mano como indicador de la capacidad funcional y grado de autonomía para actividades cotidianas en personas de la tercera edad. Diseño: Se realizó un estudio observacional de diseño transversal. Emplazamiento: Medio comunitario. Centros cívicos, centros culturales y residencias de la tercera edad de la comarca del Bages (Barcelona). 2 Participantes: Se estudió a 61 personas, 40 mujeres y 21 hombres, con un rango de edad comprendido entre los 65 y 90 años, quienes no presentaban afecciones invalidantes graves. Se solicitó su colaboración y aceptación voluntaria tras informar del objetivo del estudio. Mediciones principales: El grado de autonomía funcional se valoró mediante el test de Barthel y el test de Lawton-Brody, y el riesgo de caída mediante el test de Tinetti. La fuerza muscular máxima voluntaria (FMMV) se determinó mediante el test de prensión de la mano (handgrip). Resultados: Los hombres mostraron una correlación positiva y estadísticamente significativa (p=0.001) entre la fuerza prensil de la mano y el grado de autonomía funcional y el menor riesgo de caída (p=0.037). Dicha correlación no fue observada en las mujeres respecto al grado de autonomía (p=0.232) y fue escasa para el riesgo de caída (p=0.048). Conclusiones: El test de handgrip es una herramienta potencialmente útil para estimar la autonomía funcional e instrumental y el riesgo de caídas, especialmente en varones que sobrepasan los 65 años.Objective: To determine the hand strength as an indicator of functional ability and degree of autonomy in activities of daily living for older people. Design: An observational study of transversal design. Setting: Community setting. Civic centres, cultural centres and residences of the third age of the region of the Bages (Barcelona). Participants: We studied 61 subjects, 40 women and 21 men, age 65 to 90 years, who had no serious disabling conditions. Requested his collaboration and voluntary acceptance after informing of the aim of the study. Main measurements: The degree of functional autonomy was assessed by the Barthel and Lawton-Brody test, and the risk of falling through the Tinetti test. The maximum voluntary hand strength was determined by the handgrip test. Results: Men showed a statistically significant positive correlation (p = 0.001) between the handgrip strength and the degree of functional autonomy and a reduced risk of falling (p = 0.037). This correlation was not observed in women on the degree of autonomy (p = 0.232) and was limited to the risk of falling (p = 0.048). Conclusions: The handgrip test is a potentially useful tool to estimate the functional and instrumental autonomy and the risk of falls, especially in men older of 65 years

Oxaliplatin plus raltitrexed and leucovorin-modulated 5-fluorouracil i.v. bolus: a salvage regimen for colorectal cancer patients

The aim of the present study was to define the activity and tolerability of a triplet regimen including oxaliplatin 130 mg m−2 (2 h i.v. infusion) and raltitrexed 3.0 mg m−2 (15 min i.v. infusion) given on day 1, followed by levo-folinic acid 250 mg m−2 (2 h i.v. infusion) and 5-fluorouracil 1050 mg m−2 i.v. bolus on day 2, every 2 weeks, in pretreated colorectal cancer patients. From April 1999 to December 2000, 50 patients were enrolled: 26 were males and 24 females, their median age was 63 (range, 43–79) years; ECOG performance status was 0 in 26 patients, ⩾1 in 24 patients; 26 patients had received previous adjuvant chemotherapy, 40 patients had been exposed to one or two lines of palliative chemotherapy (including irinotecan in 31 cases); 18 patients were considered chemo-refractory. A total of 288 cycles were administered, with a median number of 6 (range 1–12) courses per patient. A complete response was obtained in three patients, and a partial response in nine patients, giving a major response rate of 24% (95% confidence interval, 13–38%), while 15 further patients showed a stable disease, for an overall control of tumour growth in 60% of patients. Three complete responses and three partial responses were obtained in patients pretreated with irinotecan (response rate, 19%); among refractory patients, three achieved partial responses (response rate, 13%). After a median follow-up of 18 (range, 10–30) months, 40 patients showed a progression of disease: the growth modulation index ranged between 0.2 and 2.5: it was ⩾1.33 (showing a significant delay of tumour growth) in 16 (40%) patients. Actuarial median progression-free survival time was 7.6 months, and median survival time was 13.6 months: estimated probability of survival was 55% at 1 year. Main severe toxicity was neutropenia: World Health Organisation grade 4 affected 32% of patients; non-haematological toxicity was mild: World Health Organisation grade 3 diarrhoea was complained of by 8%, and grade 3 stomatitis by 4% of patients; neurotoxicity (according to Lévi scale) was scored as grade 3 in 8% of patients. In conclusion, this regimen was manageable and active as salvage treatment of advanced colorectal cancer patients; it showed incomplete cross-resistance with irinotecan-based treatments, and proved to delay the progression of disease in a relevant proportion of treated patients

Concomitant MPZ and MFN2 Gene Variants and Charcot Marie Tooth Disease in a Boy: Clinical and Genetic Analysis-Literature Review

: Charcot- Marie- Tooth (CMT) disease includes a group of clinically and genetically heterogeneous neuropathic disorders with an estimated frequency of 1 on 2.500 individuals. CMTs are differently classified according to the age of onset, type of inheritance, and type of inheritance plus clinical features. For these disorders, more than 100 genes have been implicated as causal factors, with mutations in the PMP22 being one of the most common. The demyelinating type (CMT1) affects more than 30% of the CMTs patients and manifests with motor and sensory dysfunctions of the peripheral nervous system mainly starting with slow progressive weakness of the lower extremities. We report here a 12 year- old boy presenting with typical features of CMT1 type, hearing impairment, and inguinal hernia who at the next-generation sequence analysis displayed a concomitant presence of two variants: the c.233 C>T p.Ser 78Leu of the MPZ gene (NM_000530.6) characterized as pathogenetic and the c.1403 G>A p.Arg 468His of the MFN2 gene (NM_014874.3) characterized as VUS. Concomitant variant mutations in CMTs have been uncommonly reported. The role of these gene mutations on the clinical expression and a literature review on this topic is discussed

Cervical dystonia incidence and diagnostic delay in a multiethnic population.

BackgroundCurrent cervical dystonia (CD) incidence estimates are based on small numbers in relatively ethnically homogenous populations. The frequency and consequences of delayed CD diagnosis is poorly characterized.ObjectivesTo determine CD incidence and characterize CD diagnostic delay within a large, multiethnic integrated health maintenance organization.MethodsWe identified incident CD cases using electronic medical records and multistage screening of more than 3 million Kaiser Permanente Northern California members from January 1, 2003, to December 31, 2007. A final diagnosis was made by movement disorders specialist consensus. Diagnostic delay was measured by questionnaire and health utilization data. Incidence rates were estimated assuming a Poisson distribution of cases and directly standardized to the 2000 U.S. census. Multivariate logistic regression models were employed to assess diagnoses and behaviors preceding CD compared with matched controls, adjusting for age, sex, and membership duration.ResultsCD incidence was 1.18/100,000 person-years (95% confidence interval [CI], 0.35-2.0; women, 1.81; men, 0.52) based on 200 cases over 15.4 million person-years. Incidence increased with age. Half of the CD patients interviewed reported diagnostic delay. Diagnoses more common in CD patients before the index date included essential tremor (odds ratio [OR] 68.1; 95% CI, 28.2-164.5), cervical disc disease (OR 3.83; 95% CI, 2.8-5.2), neck sprain/strain (OR 2.77; 95% CI, 1.99-3.62), anxiety (OR 2.24; 95% CI, 1.63-3.11) and depression (OR 1.94; 95% CI, 1.4-2.68).ConclusionsCD incidence is greater in women and increases with age. Diagnostic delay is common and associated with adverse effects. © 2019 International Parkinson and Movement Disorder Society

Baseline physical functioning status of metastatic colorectal cancer patients predicts the overall survival but not the activity of a front-line oxaliplatin-fluoropyrimidine doublet

No differences in response rate (RR), progression-free survival (PFS), overall survival (OS) and quality of life (QoL) were seen in patients randomly treated with biweekly oxaliplatin plus either fluorouracil/folinic acid or capecitabine
