Background: Pelvic organ prolapse (POP) increases in incidence and severity with aging. At least 1 in 4 women seek pelvic floor care and many more suffer with concurrent symptoms of bowel, bladder and sexual dysfunction, which can have a large impact on quality of life. It is estimated that 1 in 5 women will undergo surgery for POP.

Sacrospinous ligament suspension is used for suspension of apical prolapse; however, it has a high rate of recurrence compared with sacrocolpopexy, and a high rate of pain compared with uterosacral suspension. We developed a novel surgical procedure of bilateral sacrospinous vaginal vault fixation with synthetic mesh arms. We previously demonstrated its safety, and in Supplementary video 1, we describe a step-by-step surgical approach that could be replicated.

Muscle dysfunction and muscle atrophy are common complications resulting from Chronic Obstructive Pulmonary Disease (COPD). The evaluation of the peripheral muscles can be carried out through the assessment of their structural components from ultrasound images or their functional components through isometric and isotonic strength tests. This evaluation, performed mainly on the quadriceps muscle, is not only of great interest for diagnosis, prognosis and monitoring of COPD, but also for the evaluation of the benefits of therapeutic interventions.

Although transcranial direct current stimulation constitutes a non-invasive neuromodulation technique with promising results in a great variety of applications, its clinical implementation is compromised by the high inter-subject variability reported. This study aims to analyze the inter-subject variability in electric fields (E-fields) over regions of the cortical motor network under two electrode montages: the classical C3Fp2 and an alternative P3F3, which confines more the E-field over this region.Computational models of the head of 98 healthy subjects were developed to simulate the E-field under both montages.
