ReviewPathogenesis, clinical manifestations and complications of coronavirus disease 2019 (COVID-19).
Aim: Despite the similarities in the pathogenesis of the beta coronaviruses, the precise infective mechanisms of SARS-CoV-2 remain unclear. Objective: In this review, we aim to focus on the proposed theories behind the pathogenesis of SARS-CoV-2 and highlight the clinical complications related to COVID-19. ⋯ Conclusion: Respiratory system and the lungs are the most commonly involved sites of COVID-19 infection. Cardiovascular, liver, kidneys, gastrointestinal and central nervous systems are involved with different frequencies and degrees of severity.

Safety, immunogenicity and risk-benefit analysis of rVSV-ΔG-ZEBOV-GP (V920) Ebola vaccine in Phase I-III clinical trials across regions.
To evaluate the risk-benefits balance of the rVSV-ΔG-ZEBOV-GP vaccine. We performed a systematic review to summarize data on safety, immunogenicity and efficacy. ⋯ The 20 million plaque-forming units dose yielded GP-specific antibody titres which peaked at day 28 with a pooled geometric mean titres of 2557.7 (95% CI: 1665.5-3934.2) versus 1156.9 (95% CI: 832.5-1649.2) but with similar seroconversion rates at 96% (95% CI: 87-100) versus 100% (95% CI: 90-100) for HICs and LMICs, respectively. Data from stringent Phase I-II clinical trials in LMICs and HICs and from the ring efficacy trials yielded a good risk-benefit balance of the V920 vaccine in adults, but also in children and pregnant and lactating women and HIV-infected people.

ReviewTherapeutic potential of lefamulin in the treatment of community-acquired pneumonia.
Despite the increasing availability of antibiotics with activity against pathogens that cause community-acquired pneumonia (CAP), CAP remains a major cause of morbidity, hospital admissions and re-admissions, and mortality. Lefamulin is a novel pleuromutilin antibiotic with potent in vitro activity against both typical and atypical CAP pathogens. In this review of the medical literature, we summarize the available information, including mounting clinical evidence, about lefamulin and its potential value in CAP.

ReviewClostridioides (Clostridium) difficile infection: current and alternative therapeutic strategies.
Clostridioides difficile (C. difficile) has become a pathogen of worldwide importance considering that epidemic strains are disseminated in hospitals of several countries, where community-acquired infections act as a constant source of new C. difficile strains into hospitals. Despite the advances in the treatment of infections, more effective therapies against C. difficile are needed but, at the same time, these therapies should be less harmful to the resident gastrointestinal microbiota. The purpose of this review is to present a description of issues associated to C. difficile infection, a summary of current therapies and those in developmental stage, and a discussion of potential combinations that may lead to an increased efficacy of C. difficile infection treatment.

ReviewOmadacycline: development of a novel aminomethylcycline antibiotic for treating drug-resistant bacterial infections.
Omadacycline is a first-in-class aminomethylcycline antibiotic that circumvents common tetracycline resistance mechanisms. In vitro omadacycline has potent activity against Gram-positive aerobic bacteria including methicillin-resistant Staphylococcus aureus, penicillin-resistant and multidrug-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus spp. ⋯ Ongoing Phase III clinical trials with omadacycline are investigating once daily doses of 100 mg intravenously followed by once-daily doses of 300 mg orally for the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia. This paper provides an overview of the microbiology, nonclinical evaluations, clinical pharmacology and initial clinical experience with omadacycline.
