vaginal delivery for pregnant women with COVID-19. Premature delivery was the main adverse event for newborns. The vertical transmission rate calculated by SARS-CoV-2 nucleic acid tests was 3.91%. Serum antibodies against SARS-CoV-2 should be tested more frequently, and multiple samples should be included in pathogenic testing.

Obstetric anal sphincter injuries (OASIS) increase the risk for pelvic floor dysfunctions. The goal of this study was to examine the long-term outcomes after OASIS on pelvic floor functions and quality of life.

Between 2005 and 2013, 424 women had an OASIS at the Women University Hospital Ulm. Out of these 71 women completed the German pelvic floor questionnaire, which includes questions regarding prolapse symptoms as well as bladder, bowel and sexual function. In addition, 64 women were physically examined, including a speculum examination to evaluate the degree of prolapse, a cough test to evaluate urinary stress incontinence (SI) and an evaluation of both pelvic floor sphincter (modified Oxford score) and anal sphincter contraction.

A high rate of pelvic floor disorders after OASIS was found, as 74.6% of women reported SI, 64.8% flatus incontinence and 18.3% stool incontinence, respectively. However, only few women stated a substantial negative impact on quality of life. The clinical examination showed that a positive cough test, a weak anal sphincter tone and a diagnosed prolapse correlated with the results of the self-reported questionnaire.

On one hand, OASIS has an influence on pelvic floor function going along with lots of complaints, while on the other hand, it still seems to be a taboo topic, as none of the participants spoke about the complaints after OASIS with a doctor. Therefore, the gynecologist should actively address these issues and offer therapy options for the women with persisting problems.

Persistent activation of valvular endothelial cells leads to leaflet fibrosis through endothelial-to-mesenchymal transition (EMT). Tenascin C (TNC), an extracellular matrix glycoprotein involved in cardiovascular remodeling and fibrosis, was also identified in inducing epithelial-to-mesenchymal transition. In this study, we hypothesized that TNC also plays a role in the valvular remodeling observed in ischemic MR by contributing to valvular excess EMT. Moderate ischemic MR was induced by creating a posterior papillary muscle infarct (7 pigs and 7 sheep). Additional animals (7 pigs and 4 sheep) served as controls. Pigs and sheep were sacrificed after 6 weeks and 6 months, respectively. TNC expression was upregulated in the pig and sheep experiments at 6 weeks and 6 months, respectively, and correlated well with leaflet thickness (R = 0.68; p  less then  0.001 at 6 weeks, R = 0.84; p  less then  0.001 at 6 months). To confirm the translational potential of our findings, we obtained mitral valves from patients with ischemic cardiomyopathy presenting MR (n = 5). Indeed, TNC was also expressed in the mitral leaflets of these. Furthermore, TNC induced EMT in isolated porcine mitral valve endothelial cells (MVEC). Interestingly, Toll-like receptor 4 (TLR4) inhibition prevented TNC-mediated EMT in MVEC. We identified here for the first time a new contributor to valvular remodeling in ischemic MR, namely TNC, which induced EMT through TLR4. Our findings might set the path for novel therapeutic targets for preventing or limiting ischemic MR.Recently commenced host-parasite interactions provide an excellent opportunity to study co-evolutionary processes. Multi-host systems are especially informative because variation in virulence between hosts and temporal changes provides insight into evolutionary dynamics. However, empirical data under natural conditions are scarce. In the present study, we investigated the interaction between Darwin’s finches and the invasive fly Philornis downsi whose larvae feed on the blood of nestlings. Recently, however, the fly has changed its behavior and now also attacks incubating females. Two sympatric hosts are affected differently by the parasite and parasite load has changed over time. Our study observed a reversal of trends described two decades ago while, currently, small tree finches (Camarhynchus parvulus) experience significantly higher parasite load than warbler finches (Certhidea olivacea), this was the opposite two decades ago. Currently, fledging success is higher in warbler finches compared to small tree finches. Our data indicate that not only intensity but also timing of infestation influences hosts’ reproductive success and parasite fitness. find more During incubation, prevalence was higher in warbler finches, but once chicks had hatched, prevalence was 100% in both species and parasite load was higher in small tree finches. Furthermore, our results suggest faster development and higher reproductive success of P. downsi in small tree finch nests. A change in host preference driven by larvae competition could have led to the reversal in parasite load.The immune system is an effective defense against invading pathogens and is accompanied by recruitment of immune cells and initiation of an inflammatory reaction. This can also be triggered by noninfectious stimuli, e.g. a large surgical intervention and cause severe tissue destruction and organ dysfunction. The organism cannot distinguish many stimuli that are released during a large surgical intervention from exogenous pathogens. Therefore, there is a high risk for the occurrence of systemic inflammatory reactions, particularly in large surgical interventions. This excessive immune response leads to release of proinflammatory cytokines, endothelial dysfunction, damage to the glycocalyx, activation of leukocytes as well as tissue and organ destruction. This article summarizes the molecular principles of the surgery-associated inflammatory reaction, the differentiation from other inflammatory complications and treatment options.
