Background: With its abrupt and huge health and socio-economic consequences, the coronavirus disease (COVID-19) pandemic has led to a uniquely demanding, intensely stressful, and even traumatic period. Healthcare workers (HCW), especially nurses, were exposed to mental health challenges during those challenging times.

Objectives: Review the current literature on mental health problems among nurses caring for COVID-19 patients.

The development of biological agents against tumor necrosis factor (TNF) has revolutionized the management of inflammatory bowel disease (IBD), frequently achieving induction and maintenance of remission in both ulcerative colitis and Crohn's disease. However, a loss of response due to the development of anti-drug antibodies (ADA) is seen annually in approximately 20% of IBD patients receiving anti-TNF therapy. Current evidence suggests that the use of immunomodulators (IMM), such as thiopurines (azathioprine and 6-mercaptopurine) or methotrexate, may prevent or suppress ADA formation.

Inflammatory bowel disease (IBD) is a multisystemic disease with a wide range of extraintestinal manifestations in both ulcerative colitis and Crohn's disease, while increasing evidence supports the interaction between gut and central nervous system, described as "gut-brain axis". According to epidemiological studies, it seems that patients with IBD present more frequently with impaired mental status compared to the general population, leading to diagnostic and management problems in this group of patients. The association between IBD and mental disorders, such as dementia and autism spectrum disorders, has not been fully clarified; genetic factors and the gut-brain axis seem to be involved.

Background: venom immunotherapy (VIT) is a clinically effective treatment. However, little is known about its long-term clinical efficacy and biological effects. Several mechanisms have been proposed to account for VIT efficacy, including reduction of specific IgE and induction of allergen-specific IgG, but the overall picture remains elusive.

Background: Randomized Controlled Trials showed that omalizumab exhibited a good safety and tolerability profile in patients with moderate-to-severe asthma. However, safety data of long-term treatment with omalizumab are scarce. Our aim was to assess the safety of omalizumab in patients under long-term treatment in a real-life setting.

Background: There is still considerable disagreement on several aspects of monitoring asthma with symptom score and peak expiratory flow (PEF).

Objective: To investigate patient adherence to a retrospective diary-card monitoring method in patients with poorly controlled persistent asthma, in a clinical management setting; to develop improved methods for fast manual entry data into a computer; and to generate real-time informative graphs of the data.

Methods: In 115 consecutive adult patients we applied a diary-card monitoring method in which the patient records symptom score and PEF.

Aim: We report on quantitative analysis of skin tests in patients undergoing Hymenoptera venom immunotherapy. The need for accuracy, coupled with a sound manual technique, in performing this procedure is emphasized. Involuntary errors may occur and pose serious problems with interpretation of results.
