[Guidelines of the European Resuscitation Council (ERC) on cardiopulmonary resuscitation 2021: update and comments].

The European guidelines on cardiopulmonary resuscitation, which are divided into 12 chapters, have recently been published. In addition to the already known chapters, the topics "epidemiology" and "life-saving systems" have been integrated for the first time. For each chapter five practical key statements were formulated.

Septum resection in women with a septate uterus: a cohort study.

Study Question: Does septum resection improve reproductive outcomes in women with a septate uterus?

Summary Answer: In women with a septate uterus, septum resection does not increase live birth rate nor does it decrease the rates of pregnancy loss or preterm birth, compared with expectant management.

What Is Known Already: The septate uterus is the most common uterine anomaly with an estimated prevalence of 0.2-2.

Pregnancy, malignancy or mother nature? Persistence of high hCG levels in a perimenopausal woman.

Despite the fact that a small percentage of peri en postmenopausal women have mild elevations in human chorionic gonadotrophin (hCG) concentrations (<14 IU/L) besides high levels of gonadotrophins, a considerable number of clinicians are not aware of this phenomenon. We report a case of a 53-year-old woman with an unusually high hCG concentration (>40 IU/L) given her menopausal state. Although a pregnancy or a malignancy was unlikely on the basis of stable hCG levels, elevated gonadotrophins and a negative transvaginal ultrasound, her physicians were uncertain and chose an expectant approach by repeated testing.

In-hospital major arrhythmias, arrhythmic death and resuscitation after successful primary percutaneous intervention for acute transmural infarction: a retrospective single-centre cohort study.

Background: Transmural acute myocardial infarction (AMI) is associated with a high risk for ventricular arrhythmia before, during and after treatment. Consequently, it is recommended that patients diagnosed with transmural AMI be monitored in a cardiac care unit (CCU) so life-threatening arrhythmias can be treated promptly. We examined the incidence and timing of in-hospital malignant ventricular arrhythmias, sudden cardiac or arrhythmic death (SCD/AD) and resuscitation requirements in patients with transmural AMI recovering from percutaneous coronary intervention (PCI) undertaken within 12 h of symptom onset and without antecedent thrombolysis.
