Validity and reliability of the Arabic version of Activities of Daily Living (ADL)

Background. The Activity of Daily Living (ADL) is an instrument that screens elderly respondents for physical functioning and assesses whether they are dependent or independent in their daily activities. This study demonstrates a translation procedure and obtains the reliability and validity of a translated, Arabic ADL. Methods. The ADL was translated to Arabic through a forward translation method followed by a committee-consensual approach. The ADL and the Arabic Mini-Mental State Examination (AMMSE) were administered to an opportunistic sample of 354 Lebanese elderly living in nursing homes who did not have dementia. Results. Reliability split half measures, sensitivity, and negative predictive values were high across all dimensions of the ADL with the exception of feeding. There were non-significant differences on the scored ADL between the three age groups: young age, middle age and older old. In addition, a non-significant difference was found on the scored ADL between the high and low AMMSE scores. Conclusion. Overall, the translated ADL was consistent and valid measure for assessing daily activities in elderly nursing home residents. As it is quick and easy to use, the ADL in Arabic could help caregivers and doctors to prescribe appropriate physical exercise for elderly Arabic speaking patients

Violencia y contrapoder: una ventana al mundo de las mujeres indígenas migrantes, en México Violence and means to counteract power: a view to migrant indigenous women in Mexico

El artículo analiza las condiciones en las que las mujeres se incorporan al sector agrícola de exportación en México. Este sector genera una fuerte demanda de mano de obra en el nivel nacional, lo cual ocasiona importantes flujos de migración en los que algunas indígenas participan de manera significativa. El artículo muestra cómo dicha incorporación de mano de obra femenina al mercado de trabajo pone en juego desigualdades de género y étnicas que se traducen en una segmentación dentro de las ramas y sectores de la economía. Asimismo, el estudio describe los procesos a que recurren las indígenas con el fin de contrarrestar la violencia real y simbólica de que son objeto.<br>The article analizes the conditions in which women farmers incorporate into México&#8217;s exports processes. This sector has a great need of labour at the national level, which in turn brings about many migration fluxes in which indigenous women play an important role. The study shows how this feminine incorporation into the labour market triggers gender as well as ethnic inequalities that manifest themselves in a segmentation within the branches and sectors of the national economy. Also, the article describes the means to which indigenous women turn to in order to counteract the actual and symbolic violence they are submitted to

Nusinersen Versus Sham Control In Infantile-Onset Spinal Muscular Atrophy

BACKGROUND & para;& para;Spinal muscular atrophy is an autosomal recessive neuromuscular disorder that is caused by an insufficient level of survival motor neuron (SMN) protein. Nusinersen is an antisense oligonucleotide drug that modifies pre-messenger RNA splicing of the SMN2 gene and thus promotes increased production of full-length SMN protein.& para;& para;METHODS & para;& para;We conducted a randomized, double-blind, sham-controlled, phase 3 efficacy and safety trial of nusinersen in infants with spinal muscular atrophy. The primary end points were a motor-milestone response (defined according to results on the Hammersmith Infant Neurological Examination) and event-free survival (time to death or the use of permanent assisted ventilation). Secondary end points included over all survival and subgroup analyses of event-free survival according to disease duration at screening. Only the first primary end point was tested in a prespecified interim analysis. To control the overall type I error rate at 0.05, a hierarchical testing strategy was used for the second primary end point and the secondary end points in the final analysis.& para;& para;RESULTS & para;& para;In the interim analysis, a significantly higher percentage of infants in the nusinersen group than in the control group had a motor-milestone response (21 of 51 infants [41 %] vs. 0 of 27 [0%], P<0.001), and this result prompted early termination of the trial. In the final analysis, a significantly higher percentage of infants in the nusinersen group than in the control group had a motor-milestone response (37 of 73 infants [51%] vs. 0 of 37 [0%]), and the likelihood of event-free survival was higher in the nusinersen group than in the control group (hazard ratio for death or the use of permanent assisted ventilation, 0.53; P=0.005). The likelihood of overall survival was higher in the nusinersen group than in the control group (hazard ratio for death, 0.37; P=0.004), and infants with a shorter disease duration at screening were more likely than those with a longer disease duration to benefit from nusinersen. The incidence and severity of adverse events were similar in the two groups.& para;& para;CONCLUSIONS & para;& para;Among infants with spinal muscular atrophy, those who received nusinersen were more likely to be alive and have improvements in motor function than those in the control group. Early treatment may be necessary to maximize the benefit of the drug.Wo
