ROX index as predictor of high flow nasal cannula therapy success in acute respiratory failure due to SARS-CoV-2.

Background: High-Flow Nasal Cannula (HFNC) therapy is useful treatment in patients with acute respiratory failure (ARF). The ROX index (ratio of pulse oximetry/fraction of inspired oxygen to respiratory rate) has been evaluated to predict success of HFNC in patients with pneumonia.

Objective: The aim of this study was to determine whether the ROX Index could predict HFNC therapy success in patients with ARF due to SARS-CoV-2 pneumonia.

Machine Learning-Based Approach Highlights the Use of a Genomic Variant Profile for Precision Medicine in Ovarian Failure.

Ovarian failure (OF) is a common cause of infertility usually diagnosed as idiopathic, with genetic causes accounting for 10-25% of cases. Whole-exome sequencing (WES) may enable identifying contributing genes and variant profiles to stratify the population into subtypes of OF. This study sought to identify a blood-based gene variant profile using accumulation of rare variants to promote precision medicine in fertility preservation programs.

Endometriosis in a postmenopausal woman without previous hormonal therapy: a case report.

Introduction: The prevalence of pelvic endometriosis is high, affecting approximately 6% to 10% of women of reproductive age. Although endometriosis has been associated with the occurrence of menstrual cycles, it can affect between 2% to 5% of postmenopausal women.

Case Presentation: We present a case of ovarian endometriosis in a 62-year-old Spanish Caucasian woman with no previous use of hormonal therapy and no history of endometriosis or infertility.

[Treatment for endometriosis].

Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, which induced a chronic inflammatory reaction. Endometriosis is associated with severe dysmenorrhea, deep dyspareunia, chronic pelvic pain, ovulation pain, cyclical, or perimenstrual symptoms, with or without abnormal bleeding, infertility, and chronic fatigue. Therapies can be useful to relieve and sometimes solve the symptoms, encourage fertility, eliminate endometrial lesions, and restore the anatomy of the pelvis.

Ultrasound study of the myoendometrial border.

Abnormal thickening of the Endometrial Subendometrial Myometrium Unit (ESEMy Unit, including basal endometrium and inner myometrium) has been detected on imaging and referred to as "diffuse adenomyosis" in infertile patients with proven endometriosis. However, no robust relationship exists between enlargement of the ESEMy Unit and adenomyosis proven on hysterectomy specimen examination; moreover, if any correlation exists, it lacks histological validation in women wishing to preserve fertility. While adenomyosis effects on fertility, if any, remain elusive, thickening of the ESEMy Unit have been consistently linked to fertility impairment in both experimental and clinical models.

Thrombospondin-1 serum levels do not correlate with pelvic pain in patients with ovarian endometriosis.

Objective: Thrombospondin-1 serum levels is correlate with pelvic pain in patients with ovarian endometriosis.

Patients: Thrombospondin-1 serum levels were prospectively analysed in 51 patients (group A asymptomatic patients or patients presenting mild dysmenorrhea and women comprised group B severe dysmenorrhea and/or chronic pelvic pain and/or dyspareunia) who underwent surgery for cystic ovarian endometriosis to asses whether a correlation exists among thrombospondin-1 serum levels and pelvic pain.

Results: From 56 patients, five cases were ultimately excluded, because the histological diagnosis was other than cystic ovarian endometriosis (2 teratomas and 3 haemorrhagic cysts).

Obesity surgery results depending on technique performed: long-term outcome.

Background: Many techniques have excellent results at 2 years of follow-up but some matters regarding their long-term efficacy have arisen. This is why bariatric surgery results must be analyzed in long-term follow-up. The aim of this study was to extend the analysis over 5 years, evaluating weight loss, morbidity, and mortality of the surgical procedures performed.

[Tunneled catheters. Complications during insertion].

Introduction: The creation of vascular accesses for hemodialysis in patients affected with terminal kidney failure affections, is presented periodically as a problem. Because of it, the availability of alternatives to the arteriovein fistula is something necessary; different types of tunnelled dialysis catheters are being developed, among which the Tesio catheter is the most well known and most widely utilized. Often it is implanted by vascular surgeons or radiologists; this creates dependence for the nephrology services that can delay obtaining the new vascular access and initiating or reinitiating the treatment.

Triage for surgical management of ovarian tumors in asymptomatic women: assessment of an ultrasound-based scoring system.

Objectives: To prospectively evaluate an ultrasound-based scoring system as a method for triaging asymptomatic women presenting with an adnexal mass for surgical treatment.

Methods: Two hundred and four adnexal masses in 189 asymptomatic women undergoing elective surgical treatment at our institution were included in this prospective study. Patients were evaluated by transvaginal power Doppler ultrasound imaging before surgery.

Three-dimensional power Doppler assessment of uterine vascularization in women with primary dysmenorrhea.

Objective: The aim of this study was to assess myometrial vascularization with 3-dimensional (3D) power Doppler angiography (PDA) in women with different grades of primary dysmenorrhea at the moment of maximum menstrual pain in an effort to improve the pathophysiologic knowledge of one of the most common gynecologic conditions.

Methods: This was a cross-sectional study involving 70 voluntary women that studied or worked at the Clinica Universitaria de Navarra between January 2006 and January 2008. All women underwent transvaginal sonographic 3D PDA on the day of maximum pain after the onset of menstruation or during the first 24 to 48 hours of the new cycle if no pain was present.
