Short-term Results of Hemiarthroplasty of the Ankle Joint for Talar-Sided Cartilage Loss.

Background: Ankle hemiarthroplasty is a 1-piece implant system replacing the talar side of the tibiotalar joint. Hemiarthroplasty offers limited bone resection and may provide easier revision options than joint-ablating procedures.

Methods: Prospective, multicenter, noncomparative, nonrandomized clinical study with short term follow-up on patients undergoing hemiarthroplasty of the ankle.

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.

Safety and Non-Inferiority Evaluation of Two Immunization Schedules with an Inactivated SARS-CoV-2 Vaccine in Adults: A Randomized Clinical Trial.

Several vaccines have been developed to control the COVID-19 pandemic. CoronaVac, an inactivated SARS-CoV-2 vaccine, has demonstrated safety and immunogenicity, preventing severe COVID-19 cases. We investigate the safety and non-inferiority of two immunization schedules of CoronaVac in a non-inferiority trial in healthy adults.

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.

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.

Food allergy: Children's symptom levels are associated with mothers' psycho-socio-economic variables.

Background: Allergies affect children's health as well as their quality of life, stress levels, and family budget. The available literature suggests that family, social and psychological factors are affected by allergic pathologies such as rhinitis, asthma and atopic dermatitis. However, few studies have focused on quantifying such association in child food allergy.

Validation of the English Version of the Scale for Psychosocial Factors in Food Allergy and the Relationship with Mental Health, Quality of Life, and Self-Efficacy.

Background. The Scale for Psychosocial Factors in Food Allergy (SPS-FA) is based on the biopsychosocial model of health and was developed and validated in Chile to measure the interaction between psychological variables and allergy symptoms in the child. We sought to validate this scale in an English speaking population and explore its relationship with parental quality of life, self-efficacy, and mental health.

Development of the scale of perceived social support in HIV (PSS-HIV).

Social support (SS) plays a key role for HIV/AIDS prevention and disease management. Numerous general and disease-specific SS instruments have been developed and perception of support has been increasingly considered, though no scales have been specifically developed to measure perceived social support (PSS) in HIV/AIDS. To help fill this gap a 12-item scale was developed.

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.

Development of the scale of psychosocial factors in food allergy (SPS-FA).

Background: Food allergy (FA) is a growing condition among children and it's psychological impact over the patients and their caregivers is well known, establishing a vicious circle that perpetuates stress levels. However, psychosocial factors are not commonly included in allergy treatments. Based on the lack of evidence of records about a scale that indicates the level of interaction between biopsychosocial factors in the patient-caregivers dyad for FA, the present research aims to develop a scale with these characteristics as a helpful tool to achieve a more comprehensive system of health care.

The effects of abnormal blood pressure on arterial sampler filling times.

Background: Sampler filling time begins with the initial flash of blood in the needle hub until the preset sampler volume is obtained. Previous studies have shown statistically significant differences between arterial and venous sampler filling times, but included only a few subjects with abnormal blood pressures.

Objective: To determine whether the time required to fill a vented arterial sampler is an accurate indication of a successful arterial blood sample in adults with abnormal blood pressure.
