Cross-cultural adaptation and validation of the Short Musculoskeletal Function Assessment (SMFA) into Spanish (Chile).

The purpose of this protocol was to adapt and validate the English version of the Short Musculoskeletal Function Assessment (SMFA) into Chilean Spanish according to the World Health Organisation guidelines. This is a cross-sectional study of 897 surveys of patients with non-traumatic surgical orthopaedic pathologies. We analysed internal consistency, validity, and acceptability, including correlation with the short form 36 (SF-36) medical score. The validation included 900 participants with a response rate of 99,66%, with excellent internal consistency (Cronbach's α = 0.962). The Dysfunction and Bother Index items showed a value of 0.952 and 0.884 respectively, eliminating one item in the Dysfunction sub-scale. The principal component analysis was forced to four factors explaining 55.5% of the variance. SMFA-CL sub-scales are significantly correlated with SF-36 components and subcomponents. The first version of the SMFA-CL version (Spanish-Chilean) scale is reported. This culturally adapted score demonstrated a high rate of reliability, validity, and ability to objectively evaluate foot and ankle pathologies.

The use of copper to help prevent transmission of SARS-coronavirus and influenza viruses. A general review.

The SARS-CoV-2 is the causative agent of the COVID-19 disease, a severe acute respiratory syndrome-coronavirus (SARS-CoV). Its main transmission pathway is through large respiratory droplets, as well as direct and indirect contact. Copper in different formats has been used in research and clinical settings to reduce the risk of bacterial and viral contamination. Therefore, this review aims to search for evidence about the biocidal properties of copper over the Coronaviridae family. A literature review was performed using PubMed and Ovid servers without date or language restrictions. The search was carried out on March 7, 2020, using the following search terms: [Copper] Coronavirus OR CoV OR SARS OR MERS OR Influenza. Copper destroys the replication and propagation abilities of SARS-CoV, influenza, and other respiratory viruses, having high potential disinfection in hospitals, communities, and households. Copper can eliminate pathogenic organisms such as coronavirus bacterial strains, influenza virus, HIV, and fungi after a short period of exposure. Copper seems to be an effective and low-cost complementary strategy to help reduce the transmission of several infectious diseases by limiting nosocomial infectious transmission. Copper oxide or nanocompounds may be used as filters, face masks, clothing, and hospital common surfaces to reduce viruses and bacterial incubation.

Cross-cultural adaptation and validation of the Foot and Ankle Outcome Score (FAOS) into Spanish (Chile).

PURPOSE: To adapt and validate the English version of the Foot and Ankle Outcome Score (FAOS) into Spanish FAOS-CL, following the WHO guidelines. METHODS: A cross-sectional study including 318 outpatients with non-traumatic conditions. Validity, acceptability and internal consistency including correlations with the Medical Outcome Study Short Form 36 are reported. RESULTS: The preliminary version resulted from the forward and back-translation and a pilot administration. Validation response rate was 99.22%. Substantial ceiling effects were observed for Symptoms and ADL and floor effect for QoL sub-scales. The FAOS-CL had excellent internal consistency (Cronbach's α = 0.98). The principal component analysis gave five factors explaining the 72.6% of the variance. The FAOS-CL items significantly correlate with their sub-scales. FAOS-CL sub-scales significantly correlated with SF-36 components and subcomponents. CONCLUSION: The first Spanish version of the FAOS was generated. Culturally adapted and validated with high reliability capable of evaluating different foot and ankle conditions.

An 11-year-old girl with up to 19,200 coughs per day: broadening therapeutic strategies.

An 11-year-old girl was transferred to the Universidad de Chile Clinical Hospital after 2.5 months of persistent and unresponsive treatment for coughlike spasms. On arrival, the frequency of symptoms was 1 cough every 4 s, which disappeared during sleep. A multidisciplinary examination excluded allergic, viral, respiratory, epileptic, and other more usual causes of similar conditions. Two diagnoses (psychogenic cough and transient vocal tic disorder) and a mixed intervention were proposed leading to resolution in 12 days of treatment. No recurrence of symptoms was observed during several evaluations within 12 months of medical follow-up. An association between the 2 diagnoses is proposed and discussed.
