Does the use of a diving mask adapted for non-invasive ventilation in hypoxemic acute respiratory failure in individuals with and without COVID-19 increase the ratio of arterial oxygen partial pressure to fractional inspired oxygen? A randomized clinical trial.

Non-invasive ventilation (NIV) can be used in acute hypoxemic respiratory failure (AHRF); however, verifying the best interface for its use needs to be evaluated in the COVID-19 pandemic scenario. The objective of this study was to evaluate the behavior of the ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2 ratio) in patients with AHRF with and without COVID-19 undergoing NIV with the conventional orofacial mask and the adapted diving mask. This is a randomized clinical trial in which patients were allocated into four groups: i) group 1: COVID-19 + adapted mask (n=12); ii) group 2: COVID-19 + conventional orofacial mask (n=12); iii) group 3: non-COVID-19 + adapted mask (n=2); iv) group 4: non-COVID-19 + conventional orofacial mask (n=12).

Predictive Factors of Male Sexual Dysfunction After Traumatic Spinal Cord Injury.

Study Design: Observational study (Ethics Committee Number 973.648).

Objective: Evaluating the social and clinical factors associated with sexual dysfunction in men with traumatic spinal cord injury, as well as predictive factors for sexual dysfunction.

Prevalence of urinary incontinence in high-impact sports athletes and their association with knowledge, attitude and practice about this dysfunction.

Objective: To evaluate the prevalence of urinary incontinence (UI) in female athletes practising high-impact sports and its association with knowledge, attitude and practice (KAP).

Design: Observational study.

Methods: A semi-structured evaluation form, KAP survey and the International Consultation on Incontinence Questionnaire - Short Form were used.

Abdominal and pelvic floor electromyographic analysis during abdominal hypopressive gymnastics.

Introduction: Abdominal hypopressive gymnastics appeared as an alternative to traditional abdominal exercises to promote abdominal muscles strength without overloading the pelvic floor muscles (PFM). To determine the activation level of abdominal muscles and PFM and the posture influence in the level of activation in these muscles during abdominal hypopressive gymnastics, we used surface electromyography in young and healthy multipara women.

Methods: This is an observational study with eutrophic nulliparous women aged between 18 and 35 years, with abdominal skinfold less than or equal to 3 cm and active or irregularly active physical activity.
