Boosting Dose of Pfizer-BioNtech mRNA Vaccine Against SARS-CoV-2 Does Not Affect Reproductive Outcomes in In-Vitro Fertilization Patients: A Cohort Study.

Since the introduction of anti-COVID-19 mRNA vaccination, few studies have shown that reproductive outcomes in artificial reproductive technology (ART) treatments are not impaired, after receiving the two-dose regimen. Our aim was to investigate whether a boosting dose of the Pfizer-BioNtech mRNA vaccine affects reproductive outcomes in ART patients. This is a prospective observational study, including 157 consecutive in-vitro fertilization (IVF) cycles between October 1, 2021, and November 24, 2021, in a single university affiliated IVF unit.

Elevated brain-derived cell-free DNA among patients with first psychotic episode - a proof-of-concept study.

Schizophrenia is a common, severe, and debilitating psychiatric disorder. Despite extensive research there is as yet no biological marker that can aid in its diagnosis and course prediction. This precludes early detection and intervention.

[Rare tumors of the prostate or seminal vesicles. Report of a case of leiomyosarcoma].

An unusual case of leiomyosarcoma of the prostate presented as a recurrent pelvic cystic mass. Prostatic sarcoma are rare in adults with a poor prognosis. It is often difficult to determine a definite origin.

[Micro-invasive cancer of the uterine cervix].

There is no current international consensus on the classification of microcarcinomas. There is still controversy over the depth of the stroma invasion and lymph node invasion as well as on confluence of invasive spread. The FIGO classification has been used since 1985 in which microinvasive carcinomas are considered as infraclinical cancers forming a group classed as stage 1a and divided into subgroups: 1a1 = early invasion of the stroma < 1 mm in depth; 1a2 = microinvasive carcinoma with invasion < 5 mm and width < 7 mm.
