The present work aimed to evaluate, through ten different studies, the therapeutic efficacy of a new pour-on formulation, containing 1.5 per cent ivermectin +0.5 per cent abamectin, against parasites of cattle. Results obtained on trials against Rhipicephalus (Boophilus) microplus showed that the pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained superior efficacy indexes against this ectoparasite, when compared with formulations containing 0.5 per cent ivermectin, 1 per cent ivermectin and the combination of 1 per cent abamectin +20 per cent levamisole. The results of efficacy of the ivermectin+abamectin and the 0.5 per cent ivermectin against Haematobia irritans were similar. Against Cochliomyia hominivorax larvae, all pour-on formulations tested (1.5 per cent ivermectin +0.5 per cent abamectin, 0.5 per cent ivermectin and 0.5 per cent abamectin), as well as 1 per cent doramectin administered subcutaneously, were considered ineffective. Cattle medicated with 1.5 per cent ivermectin +0.5 per cent abamectin, pour-on, remained free from parasitism by Dermatobia hominis larvae during 42 days (96 per cent efficacy), while values superior to 90 per cent were obtained by 0.5 per cent ivermectin (92 per cent) and 0.5 per cent abamectin (93 per cent) until the 42nd and 35th days post treatment, respectively. Against Haemonchus placei and Oesophagostomum radiatum, the pour-on of ivermectin+abamectin showed better efficacy than the 0.5 per cent ivermectin and 0.5 per cent abamectin. As to Cooperia punctata, there was no difference regarding efficacy results obtained by the avermectins combination and abamectin. The pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained high efficacy against R. (B.) microplus, D. hominis and some species of cattle gastrointestinal helminths when compared with formulations of 0.5 per cent ivermectin and 0.5 per cent abamectin administered through the same route.

Introduction: is a soil-transmitted helminth that can lead to life-threatening hyperinfection in transplant recipients. Targeted screening based on social history alone may preclude a large proportion of seropositive patients. Our institution implemented universal screening for kidney transplant candidates.

Since December 2019, the new SARS-CoV-2 coronavirus causes COVID-19 disease worldwide, which occurs mainly in unvaccinated elderly and polymorbid patients with a more severe course and increased risk of complications and death. Vaccination and specific therapy for the disease using mainly new antiviral drugs are the way to reduce the number of infected, hospitalized patients with a more severe course. We present a case report of an at-risk polymorbid 57-year-old man who refused vaccination and standard treatment for COVID-19 disease based on misinformation from the community.

Cytomegalovirus is a major opportunistic infection after transplantation with significant morbidity and mortality for solid organ transplant recipients. Unrecognized infection with may result in significant morbidity and mortality in immunocompromised patients. Coinfection with multiple pathogens is possible, leading to diagnostic delays, and may make treatment more challenging.

Misinformation and promotion of well-intended but disproved therapies for COVID-19 have plagued evidence-based shared decision-making throughout the COVID-19 pandemic. In times of crisis, clinicians may feel that their strong inclination to prescribe potentially harmful, unproven therapies on behalf of their patients is supported by beneficence. Clinicians should mindfully identify and avoid commission bias during this pandemic, especially as more data have accumulated to assist with clinically sound decision-making.

Background: A mutation in the canine multidrug resistance gene (also referred as ), encoding for the multidrug resistance () P-glycoprotein (P-gp) transponder, causes a pathological condition known as 'ivermectin toxicosis'. The causative mutation, known since 2001, has been described to affects sheep herding breeds related to collie lineage. The present study is a retrospective investigation of the presence of mutated allele in Italian dog populations in a 5 years' time lapse.
