Antimicrobial Stewardship in Emergency Department
Despite the demonstrated effectiveness of antimicrobial stewardship programs in antibiotic consumption and minimizing multi-drug-resistant bacterium development, the characteristics of emergency departments pose a challenge to their implementation. The inclusion of rapid diagnostic tests, tracking microbiological results upon discharge, conducting audits with feedback, and implementing multimodal educational interventions have proven to be effective tools for optimizing antibiotic use in these units.

Tuberculosis Disease
Tuberculosis disease is caused by the bacterium Mycobacterium tuberculosis. It is estimated that 10 million people have developed tuberculosis disease globally, leading to 1.4 million deaths in 2019. Treatment of tuberculosis has been especially challenging due to the rise of multidrug-resistant (MDR-TB) and extensive drug-resistant (XDR-TB) tuberculosis. In addition to drug-resistant genotypes, the standard treatment of tuberculosis by first-line agents is also challenging due to toxicity and costs.

Applications of BoNT Detection
Botulinum neurotoxins (BoNTs) are produced as protein complexes by bacteria of the genus Clostridium that are Gram-positive, anaerobic and spore forming (Clostridium botulinum, C. butyricum, C. baratii and C. argentinense spp.). BoNTs show a high immunological and genetic diversity. Therefore, fast, precise, and more reliable detection methods are still required to monitor outbreaks and ensure surveillance of botulism. The botulinum toxin field also comprises therapeutic uses, basic research studies and biodefense issues.

Lung Microbiome in Critically Ill Patients
The microbiome is a diverse ecosystem that includes all host-associated microorganisms and their genomes. These microorganisms belong to various kingdoms including some potential pathogens such as bacteria, viruses and fungi. To obtain a comprehensive view of the lung microbiome, including not only bacterial but also viral and fungal data, is of great value to improve our understanding of critical lung illnesses such as VAP or ARDS. The evolution of the lung microbiome over time and the description of its dysbiosis will be key elements to improve diagnosis and preventive measures in ventilated patients.

H7N7 and H7N9 AIVs from South Korea
Avian influenza viruses (AIVs) are eight segmented, single-stranded negative-sense RNA viruses. Based on viral surface proteins, hemagglutinin (HA) and neuraminidase (NA), influenza viruses are classified into 18 HA and 11 NA subtypes. H1-16 and N1-9 have been detected in avian species, but H17-18 and N10-11 have been discovered only in bats. In particular, H5 and H7 are important subtypes because they have the potential to mutate into highly pathogenic avian influenza viruses (HPAIVs), causing severe clinical signs in poultry.

Convalescent Plasma Transfusion for COVID‐19
More than one year into the novel coronavirus disease 2019 (COVID-19) pandemic, healthcare systems across the world continue to be overwhelmed with soaring daily cases. The treatment spectrum primarily includes ventilation support augmented with repurposed drugs and/or convalescent plasma transfusion (CPT) from recovered COVID-19 patients. CPT is a promising COVID-19 therapeutic option that merits internationally coordinated RCTs to achieve a scientific risk-benefit consensus.

Cardiovascular Pathophysiology Related to COVID-19 and Clinical Phenotypes
The intricate relationship between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the cardiovascular system is an extensively studied pandemic topic, as there is an ever-increasing amount of evidence that reports a high prevalence of acute cardiac injury in the context of viral infection. In patients with Coronavirus disease 2019, COVID-19, a significant increase in serum levels of cardiac troponin or other various biomarkers was observed, suggesting acute cardiac injury, thus predicting both a severe course of the disease and a poor outcome.

Virology of Phages and Phage-Resistance in Therapy
Bacteriophages, also known simply as phages, are prokaryotic viruses that exclusively infect and kill bacteria. Phage therapy has been overshadowed in the past by the widespread use of antibiotics in Western countries. However, it has been revitalized as a powerful approach due to the increasing prevalence of antimicrobial-resistant bacteria. Although bacterial resistance to phages has been reported in clinical cases, studies on the fitness trade-offs between phage and antibiotic resistance have revealed new avenues in the field of phage therapy.

Anti-SARS-CoV-2 Activity of Glycyrrhizic Acid
Licorice, a natural medicine derived from the roots and rhizomes of Glycyrrhiza species, possesses a wide range of therapeutic applications, including antiviral properties. Glycyrrhizic acid (GL) and glycyrrhetinic acid (GA) are the most important active ingredients in licorice. Glycyrrhetinic acid 3-O-mono-β-d-glucuronide (GAMG) is the active metabolite of GL. GL and its metabolites have a wide range of antiviral activities against viruses, such as, the hepatitis virus, herpes virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and so on.

Detection of persistent virus-DNA in Formalin Fixed samples
The DNA damage and cross-linking induced by formalin fixation can hinder nucleic acid screening. This is of particular concern in the detection of low-abundance targets, such as persistent DNA viruses, present only as a part per million of the total DNA in a sample. We evaluated the analytical sensitivity of the detection of persistent viruses in tissue specimens fixed in formalin for up to 10 days. To this end, we used short amplicon qPCRs and targeted enrichment plus Next-generation sequencing.

Merkel Cell Polyomavirus and β Human Papillomavirus Types
Oncogenic viruses are recognized to be involved in some cancers, based on very well-established criteria of carcinogenicity. For cervical cancer and liver cancer, the responsible viruses are well-known (e.g., HPV, HBV); in the case of skin cancer, there are still many studies which are trying to identify the possible viral etiologic agents as principal co-factors in the oncogenic process. In order to optimize the management of skin cancer, a health condition of very high importance, it would be ideal that the screening of skin cancer for these two analysed viruses (MCPyV and beta HPV types) to be implemented in each region’s/country’s cancer centres’ molecular detection diagnostic platforms, with multiplex viral capability, optimal sensitivity, and specificity; clinically validated, and if possible, at acceptable costs. For confirmatory diagnosis of skin cancer, another method should be used, with a different principle, such as immunohistochemistry, with specific antibodies for each virus.

Chronic Hepatitis E
Hepatitis E is an inflammation of the liver caused by infection with the hepatitis E virus (HEV), and it is a major cause of acute viral hepatitis worldwide, the virus is usually transmitted via the fecal–oral route, principally via contaminated water. Chronic hepatitis E (CHE) has been identified as associated with chronic liver damage induced by HEV genotypes 3, 4, and 7—usually in immunocompromised patients such as transplant recipients. In addition, patients infected with HIV and those receiving chemotherapy for malignancy, along with patients with rheumatic disease and COVID-19, have been reported as having CHE.

Severe Thrombocytopenia as a Manifestation of COVID-19 Infection
Clinical manifestations of COVID-19 infection can range from an asymptomatic clinical form to acute respiratory distress depending on the virus gateway, viral load, host immunity, and existing comorbidities. Some patients with COVID-19 infection can present hematological changes depending on the patient’s immune response and the severity of the infection. Patients affected by the pandemic can develop platelet count changes such as thrombocytopenia. Thrombocytopenia can be detected in almost half of the patients infected by SARS-CoV-2 and in almost 95% of those critically ill.

The Diabetic Foot Ulcer
The term “neuropathy” in diabetes is a generic term that refers to the loss of sensation and steadiness of the distal limb. The loss of sensation affects peripheral blood movement. Therefore, dysregulating the protective sensation leads to systemic inflammatory status of diabetic foot ulcers (DFUs). Diabetic foot ulcers (DFUs) are characterized by a lack of angiogenesis and distal limb diabetic neuropathy.
