Abstract

In the early pregnancy decidua, lymphocytes express some activation markers on their surface, suggesting that maternal lymphocytes are activated and recognize the semiallograftic fetus. Therefore, the immunoregulation system must work to prevent fetus rejection. Recent data showed that parts of the immunoregulation system such as CD4+CD25+ regulatory T (Treg) cells, Th3 cells, Tr1 cells, regulatory NK cells, and a tryptophan-catabolizing enzyme, indolamine 2,3 deoxygenase, play very important roles in the maintenance of pregnancy. Not only Treg cells but also regulatory NK cells may inhibit maternal T cell or NK cell fetal attack.

Ob bei einer Notfalloperation nach Schenkelhalsfraktur eine Hemiarthroplastik oder eine totale Endoprothese (TEP) eingebaut wird, sollte nicht allein vom Alter der Patientinnen und Patienten abhängen. Auch über 90-Jährige können von der TEP profitieren.

25.04.2024 Hypotonie Nachrichten

Wenn unter einer medikamentösen Hochdrucktherapie der diastolische Blutdruck in den Keller geht, steigt das Risiko für schwere kardiovaskuläre Ereignisse: Darauf deutet eine Sekundäranalyse der SPRINT-Studie hin.

Bei schweren Reaktionen auf Insektenstiche empfiehlt sich eine spezifische Immuntherapie

Insektenstiche sind bei Erwachsenen die häufigsten Auslöser einer Anaphylaxie. Einen wirksamen Schutz vor schweren anaphylaktischen Reaktionen bietet die allergenspezifische Immuntherapie. Jedoch kommt sie noch viel zu selten zum Einsatz.

Beginnen ältere Männer im Pflegeheim eine Antihypertensiva-Therapie, dann ist die Frakturrate in den folgenden 30 Tagen mehr als verdoppelt. Besonders häufig stürzen Demenzkranke und Männer, die erstmals Blutdrucksenker nehmen. Dafür spricht eine Analyse unter US-Veteranen.
