Control of Frequency Combs with Passive Resonators.

Tailored optical frequency combs are generated by nesting passive etalons within mode-locked oscillators. In this work, the oscillator generates a comb of 6.8 GHz with 106 MHz side-bands.

Two Fatty Liver Conditions Masquerading as Autoimmune Hepatitis.

Acute fatty liver of pregnancy (AFLP) is a rare obstetric condition that classically presents in the third trimester or early postpartum period and can lead to liver failure and death. Only six second trimester AFLP cases have been reported in the English literature. We present the earliest case of AFLP at 15 weeks of gestation confounded by a high titer anti-nuclear antibody (ANA >1 : 1280) and concern for autoimmune hepatitis.

The comprehensive complication index (CCI): proposal of a new reporting standard for complications in major urological surgery.

Purpose: The comprehensive complication index (CCI) is a new tool for reporting the cumulative burden of postoperative complications on a continuous scale. This study validates the CCI for urological surgery and its benefits over the Clavien-Dindo-Classification (Clavien).

Material And Methods: Data from a prospectively maintained data base of all consecutive patients at a university care-center was analyzed.

Prophylactic abdominal or retroperitoneal drain placement in major uro-oncological surgery: a systematic review and meta-analysis of comparative studies on radical prostatectomy, cystectomy and partial nephrectomy.

Purpose: To systematically analyze the impact of prophylactic abdominal or retroperitoneal drain placement or omission in uro-oncologic surgery.

Methods: This systematic review follows the Cochrane recommendations and was conducted in line with the PRISMA and the AMSTAR-II criteria. A comprehensive database search including Medline, Web-of-Science, and CENTRAL was performed based on the PICO criteria.

Can an amino acid-based oral rehydration solution be effective in managing immune therapy-induced diarrhea?

Immune checkpoint inhibitor (ICPi) therapy has transformed the way we treat cancer. However, its immune related adverse events (irAEs) can be debilitating and life threatening. Immune therapy-induced diarrhea (ITID) is one of the most commonly encountered irAEs and can lead to expensive and prolonged hospitalizations.
