Vascular Damage, Thromboinflammation, Plasmablast Activation, T-Cell Dysregulation and Pathological Histiocytic Response in Pulmonary Draining Lymph Nodes of COVID-19.

Although initial immunophenotypical studies on peripheral blood and bronchoalveolar lavage samples have provided a glimpse into the immunopathology of COVID-19, analyses of pulmonary draining lymph nodes are currently scarce. 22 lethal COVID-19 cases and 28 controls were enrolled in this study. Pulmonary draining lymph nodes (mediastinal, tracheal, peribronchial) were collected at autopsy.

[Weight discordance of the second twin: effect on perinatal morbidity and mortality. An 8-year analysis of 213 twin deliveries].

In this retrospective eight-years-study we examine factors to be considered responsible for higher perinatal mortality in twins, especially in twins with discordant body weight. As a main risk factor for this we find vaginal delivery, i.e.

[Epidemiological indications for the etiology of proteinuria, hypertension in pregnancy and pre-eclampsia--a longitudinal cohort studies of all Swedish women giving birth between 1973 and 1981 to 3 singleton infants].

Based on centrally recorded data about all pregnancies that led to delivery in Sweden in the years from 1973 to 1981 this longitudinal study considers the course of pregnancies of all women who gave birth to their first three single babies during observation time especially regarding hypertension, proteinuria, pre-eclampsia and eclampsia-here subsumized under HP-disease. Incidence of HP-disease is shown to be 8.1% of all observed women, depending on the theoretical approach at a minimum of 34% and a maximum of 44% being due to primary, pregnancy-induced HP-disease.

Capillary versus arterial plasma catecholamines as markers for sympatho-adrenal activity in infants.

In this study, we investigated whether capillary plasma catecholamines can be used as a suitable substitute for arterial catecholamines. Analysis was done radioenzymatically. Catecholamine concentrations were not different in arterial and simultaneously collected "arterialized" (warmed foot) capillary plasma obtained by heel-prick from 18 neonatal intensive care patients as assessed by linear regression analysis (correlation coefficient: 0.
