Simultaneous mechanical ventilation of several patients with a single ventilator might reduce the deficit of these devices for the care of patients with acute respiratory failure due to Covid-19. ⋯ Simultaneous mechanical ventilation should be implemented by medical personnel with experience in the procedure, be restricted to two patients and carried out in the intensive care unit.

Biography Historical Article
Carl von Rokitansky, the Linné of pathological anatomy.
Carl von Rokitansky was one of the most important figures in pathological anatomy, and was largely responsible for the resurgence of Vienna as the great medical center of the world in the mid-19th century. He was born in current Hradec Králové, studied medicine in Prague and Vienna and was graduated in 1828. He was greatly influenced by the anatomy, embryology and pathology studies of Andral, Lobstein and Meckel. ⋯ It is possible that he had access to between 1,500 and 1,800 cadavers annually to be able to perform 30,000 necropsies; in addition, he reviewed several thousand more autopsies. In Handbuch der pathologischen Anatomie, published between 1842 and 1846, he made numerous descriptions: lobar and lobular pneumonia, endocarditis, diseases of the arteries, cysts in several viscera, various neoplasms and acute yellow atrophy of the liver. With his brilliant work on gross pathology, Rokitansky established the nosological classification of diseases, for which Virchow named him "the Lineé of pathological anatomy".

The way in which two clinical procedures related to infant feeding are carried out in medical consultations for children younger than six months in a health center in Mexico City is analyzed. The first one refers to infants' anthropometric measurement, and the second, to feeding modalities' identification. Corrective actions are required based on the quality of children's health care in the public sector.

The disease caused by the new SARS-CoV-2 coronavirus (COVID-19) spread rapidly from China to the entire world. Approximately one third of SARS-CoV-2-infected patients have neurological disorders, especially those classified as severe cases and that require mechanical ventilation. ⋯ So far, whether early neurological disorders such as hyposmia or anosmia, dysgeusia or ageusia, headache and vertigo are significant in the progression to the severe form of the disease or whether they are related to entry to the central nervous system via peripheral nerves has not been determined. Considering the great similarity between SARS-CoV and SARS-CoV-2, and that the severity of the condition that leads to death cannot be explained solely by lung involvement, it is important to determine whether SARS-CoV-2 potential invasion to the central nervous system is partially responsible for the severe respiratory component observed in patients with COVID-19.

Natural killer cell reconstitution after hematopoietic stem-cell transplantation in children.
After hematopoietic stem cell transplantation (HSCT), natural killer (NK) cells reconstitution is the main barrier against viral infections. ⋯ The first period of NK cell recovery occurs between three and six months after transplantation. Reconstitution is transient and the number of NK cells varies in the first years.
