International Hepato-Pancreato-Billiary Association (IHPBA) registry study on COVID-19 infections in HPB surgery patients.

Background: In response to the pandemic, the International Hepato-Pancreato-Biliary Association (IHPBA) developed the IHPBA-COVID Registry to capture data on HPB surgery outcomes in COVID-positive patients prior to mass vaccination programs. The aim was to provide a tool to help members gain a better understanding of the impact of COVID-19 on patient outcomes following HPB surgery worldwide.

Methods: An online registry updated in real time was disseminated to all IHPBA, E-AHPBA, A-HPBA and A-PHPBA members to assess the effects of the pandemic on the outcomes of HPB procedures, perioperative COVID-19 management and other aspects of surgical care.

Prognostic value of haematological parameters and [F]FDG PET/CT metabolic parameters in head and neck cancer.

Aim: To determine the usefulness of neutrophil/lymphocyte (N/L) and platelet/lymphocyte (P/L) ratios as well as quantitative [F]FDG PET/CT parameters as prognostic factors for overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) in patients with head and neck squamous cell carcinoma (HyN).

Material And Methods: Sixty-six patients (56 men) diagnosed with HyN carcinoma were retrospectively assessed over an 8-year interval. Maximum SUV (SUV), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) parameters were determined from the PET/CT study at diagnosis.

Selective Indication of T-Tube in Liver Transplantation: Prospective Validation of the Results of a Randomized Controlled Trial.

Background And Aims: T-tube placement during choledochocholedochostomy (CCS) associated with liver transplantation (LT) remains controversial. This study was designed to validate the results of an earlier prospective randomized controlled trial (RCT) on use versus nonuse of the T-tube during CCS associated with LT.

Methods: Prospective cohort study.

Prognostic Value of Pre-transplantation Serum Alpha-Fetoprotein Levels in Hepatocellular Carcinoma Recurrence.

Serum alpha-fetoprotein (AFP) value is still not included in the consensus guidelines to make decisions referring to liver transplantation (LT) for hepatocellular carcinoma (HCC). Many studies demonstrated the influence of high AFP level in poor prognosis after LT for HCC. We studied 301 consecutive recipients transplanted for HCC from January 2002 to December 2011.

Design, fabrication and charge recombination analysis of an interdigitated heterojunction nanomorphology in P3HT/PC(70)BM solar cells.

In this work interdigitated heterojunction photovoltaic devices were manufactured. A donor layer of P3HT nanopillars was fabricated by soft nanoimprinting using nanoporous anodic alumina templates. Subsequently, the PC70BM acceptor layer was deposited by spin coating on top of the P3HT nanopillars using a solvent that would not dissolve any of the previous material.
