Implications of Flaviviruses Immunity on ZIKV Vaccine
The Zika virus (ZIKV) was first isolated from a rhesus macaque in the Zika forest of Uganda in 1947. Isolated cases were reported until 2007, when the first major outbreaks of Zika infection were reported from the Island of Yap in Micronesia and from French Polynesia in 2013. In 2015, ZIKV started to circulate in Latin America, and in 2016, ZIKV was considered by WHO to be a Public Health Emergency of International Concern due to cases of Congenital Zika Syndrome (CZS), a ZIKV-associated complication never observed before. After a peak of cases in 2016, the infection incidence dropped dramatically but still causes concern because of the associated microcephaly cases, especially in regions where the dengue virus (DENV) is endemic and co-circulates with ZIKV. A vaccine could be an important tool to mitigate CZS in endemic countries. However, the immunological relationship between ZIKV and other flaviviruses, especially DENV, and the low numbers of ZIKV infections are potential challenges for developing and testing a vaccine against ZIKV.

HIV-Associated Tuberculosis in Adolescents
Children and adolescents living with HIV continue to be impacted disproportionately by tuberculosis as compared to peers without HIV. HIV can impact tuberculosis (TB) screening and diagnosis by altering screening and diagnostic test performance and can complicate prevention and treatment strategies due to drug–drug interactions. Post-tuberculosis lung disease is an underappreciated phenomenon in children and adolescents, but is more commonly observed in children and adolescents with HIV-associated tuberculosis.

HIV and Drug-Resistant Subtypes
Acquired Immunodeficiency Syndrome (AIDS) is a human viral infectious disease caused by the positive-sense single-stranded (ss) RNA Human Immunodeficiency Virus (HIV) (Retroviridae family, Ortervirales order). HIV-1 can be distinguished into various worldwide spread groups and subtypes. HIV-2 also causes human immunodeficiency, which develops slowly and tends to be less aggressive. HIV-2 only partially homologates to HIV-1 despite the similar derivation. Antiretroviral therapy (ART) is the treatment approved to control HIV infection, based on multiple antiretroviral drugs that belong to different classes: (i) NNRTIs, (ii) NRTIs, (iii) PIs, (iv) INSTIs, and (v) entry inhibitors. These drugs, acting on different stages of the HIV life cycle, decrease the patient’s total burden of HIV, maintain the function of the immune system, and prevent opportunistic infections.

Exosomes' Signaling Pathways in Promoting Diabetic Wound Healing
Impaired healing of diabetic wounds harms patients’ quality of life and even leads to disability and death, which is an urgent issue to be solved clinically. Exosomes have attracted special attention because they can be involved in immune response, antigen presentation, cell migration, cell differentiation, tumor invasion and other processes. The signaling pathways that exosomes modulate to accelerate diabetic wound healing include PI3K/Akt, Wnt, NF-κB, MAPK, Notch, Nrf2, HIF-1α/VEGF, TGF-β/Smad and so on.

Inherent Human Susceptibility to Fungal Diseases
In medical mycology, the main context of disease is iatrogenic-based disease. However, fungal diseases affect humans with no obvious risk factors, sometimes in a spectacular fashion. The field of “inborn errors of immunity” (IEI) has deduced at least some of these previously enigmatic cases; accordingly, the discovery of single-gene disorders with penetrant clinical effects and their immunologic dissection have provided a framework with which to understand some of the key pathways mediating human susceptibility to mycoses.

Molecular Targeted Therapy in Children with Hematological Malignancies
Targeted therapy differs from the conventional cytotoxic therapy in its specificity of targeted pathways that can halt the growth and spread of cancer cells rather than killing indiscriminately every rapidly dividing cell. Since 1985 when the first agent targeting antigens on the surface of lymphocytes was approved (muromonab-CD3), a multitude of such therapies have been used in children with hematologic malignancies.

Mycobacterium avium ssp. paratuberculosis and Crohn’s Disease
Mycobacterium avium ssp. paratuberculosis (MAP) is the cause of Johne’s disease (JD), which is a chronic infectious gastrointestinal disease of ruminants and is often fatal. In humans, MAP has been associated with Crohn’s disease (CD) for over a century, without conclusive evidence of pathogenicity. Numerous researchers have contributed to the subject, but there is still a need for evidence of the causation of CD by MAP.

Animal-Associated Methicillin-Resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus (MRSA) remains an important etiological factor of human and animal infectious diseases, causing significant economic losses not only in human healthcare but also in the large-scale farming sector. The constantly changing epidemiology of MRSA observed globally affects animal welfare and raises concerns for public health. High MRSA colonization rates in livestock raise questions about the meaning of reservoirs and possible transmission pathways, while the prevalence of MRSA colonization and infection rates among companion animals vary and might affect human health in multiple ways.

Insight on Infections in Diabetic Setting
The correlation between diabetes mellitus and infectious diseases is widely recognized. DM patients are characterized by the impaired function of the immune system. This translates into the occurrence of a variety of infections, including urinary tract, skin and surgical site infections, pneumonia, tuberculosis, and, more recently, SARS-CoV-2.

High-Dose Nebulized Colistin Methanesulfonate in Hospital-Acquired Pneumonia
Hospital-acquired pneumonia, including ventilator-associated pneumonia (VAP) due to difficult-to-treat-resistant (DTR) Gram-negative bacteria, contributes significantly to morbidity and mortality in ICUs. In the era of COVID-19, the incidences of secondary nosocomial pneumonia and the demand for invasive mechanical ventilation have increased dramatically with extremely high attributable mortality. Treatment options for DTR pathogens are limited. Therefore, an increased interest in high-dose nebulized colistin methanesulfonate (CMS), defined as a nebulized dose above 6 million IU (MIU), has come into sight.

Nitric Oxide as a Therapeutic Agent against SARS-CoV-2
Nitric oxide (NO) is a key player in both the cardiopulmonary and immune systems, which has already been reported as a worthy candidate for use in the treatment of human coronavirus infections, including COVID-19, because of its antivirus activity and its beneficial effects in the treatment of clinical complications in patients. In fact, inhaled nitric oxide (iNO), as a potent vasodilator, was approved to improve oxygenation in term and near-term neonates, and has been used in clinical settings. Along with its putative antiviral affect, iNO can reduce inflammatory cell-mediated lung injury by inhibiting neutrophil activation, lowering pulmonary vascular resistance, and decreasing edema in the alveolar spaces, thus collectively enhancing ventilation/perfusion matching.

TDM-Guided Recommendations in Septic Critically Ill Patients
Optimizing the entire therapeutic regimen in septic critically ill patients should be based not only on improving antibiotic use but also on optimizing the entire therapeutic regimen by considering possible drug–drug or drug–nutrient interactions. There are reports of endocarditis, meningitis, peritonitis, or pneumonia associated with probiotics in critically ill patients. In addition, probiotics are associated with risk of the spread of antimicrobial resistance. The therapeutic drug monitoring (TDM)-guided method ensures a true optimization of antibiotic therapy, and particular efforts should be applied globally.

Principles of Rational COVID-19 Therapy in Pediatrics
A structural analysis of the range of drugs and treatment strategies in the context of etiotropic, pathogenetic, and symptomatic therapy has shown that in the global context and in real clinical practice, the etiotropic-pathogenetic approach based on information about the effectiveness of individual medical technologies prevails today. It has been established that eight international nonproprietary/grouping names are present in international practice as means of etiotropic therapy for pediatric patients with COVID-19, and 18 positions are used for pathogenetic therapy. In terms of frequency of occurrence, the leading positions are occupied by remdesivir and the combination of nirmatrelvir with ritonavir, as well as dexamethasone and tocilizumab.

Antimicrobial Stewardship Programs in Latin American Emergency Departments
Antibiotic stewardship (AS) programs have become a priority for health authorities to reduce the number of infections by super-resistant microorganisms. The need for these initiatives to minimize the inadequate use of antimicrobials is essential, and the election of the antibiotic in the emergency department usually impacts the choice of treatment if the patients need hospital admission, becoming an opportunity for antibiotic stewardship. In the pediatric population, broad-spectrum antibiotics are more likely to be overprescribed without any evidence-based management, and most of the publications have focused on the prescription of antibiotics in ambulatory settings.

Sinonasal Orbital Apex Syndrome
Rhinosinusitis (RS) is an inflammatory disease of the nose and paranasal sinuses with a clinical picture of anterior or posterior nasal discharge, congestion, olfactory dysfunction, and facial pain or pressure. It must be confirmed with endoscopic or radiological signs of inflammation. By its duration, it is classified into acute (i.e., duration <4 weeks), subacute (4–12 weeks), and chronic RS (>12 weeks). Moreover, RS can be named according to the inflamed paranasal sinus, e.g., sphenoiditis in sphenoid sinus inflammation. RS significantly affects the patient’s quality of life due to the significant impact on personal development, sleep hygiene, mental health, physical condition, self-perception, and family relationships.
