Primary Resistance to Immunotherapy-Based Regimens in First Line Hepatocellular Carcinoma: Perspectives on Jumping the Hurdle.

Immune checkpoint inhibitors (ICIs) are a key component of different stages of hepatocellular carcinoma (HCC) treatment, particularly in the first line of treatment. A lesson on the primary resistance which hampers their efficacy and activity was learned from the failure of the trials which tested them as first-line mono-therapies. Despite the combination of anti-PD(L)1 agents with anti-VEGF, anti CTLA4, or TKIs demonstrating relevant improvements in efficacy, the "doublets strategy" still shows room for improvement, due to a limited overall survival benefit and a high rate of progressive disease as best response.

Near-ground effect of height on pollen exposure.

The effect of height on pollen concentration is not well documented and little is known about the near-ground vertical profile of airborne pollen. This is important as most measuring stations are on roofs, but patient exposure is at ground level. Our study used a big data approach to estimate the near-ground vertical profile of pollen concentrations based on a global study of paired stations located at different heights.

Ragweed allergy: Pollen count and sensitization and allergy prevalence in two Italian allergy centers.

Background: Ragweed allergy represents a challenge for allergists due to its increase in some geographic areas, mainly northern Italy.

Objectives: To compare two allergy centers in northern Italy by analyzing both the pollen count and the patient characteristics (sensitization and allergy prevalence) over a 10-year period.

Methods: Pollen counts for 10 years (2004-2013) were evaluated and compared in the two centers.

Effects of pulmonary rehabilitation on lung function in chronic obstructive pulmonary disease: the FIRST study.

Background: Chronic obstructive pulmonary disease (COPD) causes an impairment of respiratory function, well reflected by the progressive decrease in forced expiratory volume in 1 second (FEV1). The only interventions able to slow down the FEV1 decline are smoking cessation and drug treatment. Pulmonary rehabilitation (PR), is claimed to improve exercise tolerance, symptoms and quality of life, but its effects on lung function have been scantly investigated.
