Human Streptococcus suis Disease in Southeast Asia
The public health systems of Southeast Asian countries are financially challenged by a comparatively higher incidence of human S. suis infections than other geographical areas. Efforts to improve practices in production settings, including improved meat inspection regulations, prevention of the slaughtering of non-healthy pigs, and enhanced hygiene practices at processing facilities, along with improvements in the pork supply chain, all appear promising for reducing food cross-contamination with S. suis.

Gas6/TAM Axis Involvement in COVID-19 Patients
Gas6 (growth arrest-specific gene 6) is a widely expressed vitamin K-dependent protein that is involved in many biological processes such as homeostatic regulation, inflammation and repair/fibrotic processes. It is known that it is the main ligand of TAMs, a tyrosine kinase receptor family of three members, namely MerTK, Tyro-3 and Axl, for which it displays the highest affinity. Gas6/TAM axis activation is known to be involved in modulating inflammatory responses as well as fibrotic evolution in many different pathological conditions. The Axl is a SARS-CoV-2 infection driver, the use of existing Axl inhibitors is beneficial for COVID-19 management.

Microbial Natural Products and COVID-19 Infection
The SARS-CoV-2 virus, which caused the COVID-19 infection, was discovered two and a half years ago. It caused a global pandemic, resulting in millions of deaths and substantial damage to the worldwide economy. Only a few vaccines and antiviral drugs are available to combat SARS-CoV-2. However, there has been an increase in virus-related research, including exploring new drugs and their repurposing. Since discovering penicillin, natural products, particularly those derived from microbes, have been viewed as an abundant source of lead compounds for drug discovery.

Nanostructures and Combating Oral Bacterial Diseases
The oral cavity is an ideal environment for microbial cell growth, survival, and stability, followed by oral biofilm formation on the tooth surface. Biofilms contain a set of bacteria that are produced in extracellular polymeric substances (EPS). Bacterial growth results in the conversion of bacterial biofilm from commensal plaque to a pathogenic form. Bacteria present in the biofilm are significantly less sensitive to antimicrobial agents than planktonic bacteri.

Nanotechnology-Based Drug Delivery to Control Bacterial-Biofilm-Associated Lung Infections
Airway mucus dysfunction and impaired immunological defenses are hallmarks of several lung diseases, including asthma, cystic fibrosis, and chronic obstructive pulmonary diseases, and are mostly causative factors in bacterial-biofilm-associated respiratory tract infections. To combat bacterial biofilm in the respiratory tract, researchers have developed various strategies, including a pipeline of new antibiotics, biofilm biomatrix disruption, quorum sensing inhibition, biofilm dispersion promotion, or combinations of these. Among the strategies, nanoparticle-based drug delivery systems have received increasing attention for delivering antibiotics to biofilm sites or enhancing anti-biofilm activity through the nanoparticles themselves.

Iron in Health and Disease
Iron dysregulation is a common characteristic in many subtypes of acute lung injury (ALI). On the one hand, iron is needed to produce reactive oxygen species (ROS) as part of the immune response to an infection; on the other hand, iron can accelerate the occurrence of ferroptosis and extend host cell damage. Iron chelation represents a novel therapeutic strategy for alleviating lung injury and improving the survival of patients with ALI.

Tocilizumab in COVID-19
Tocilizumab (TCZ) is a humanized monoclonal antibody that, via the binding to soluble and membrane interleukin (IL)-6 receptors, produces inhibition of the proinflammatory signals. It is commonly used in several types of inflammatory arthritis, in Castleman’s syndrome, and in cytokine release syndrome secondary to chimeric antigen receptor T cell therapies. Given its ability to intercept proinflammatory cascades, TCZ is potentially useful in all clinical conditions produced by the dysregulation of inflammatory processes, especially when refractory to other approved treatments.

Hepatitis B Surface Antigen Isoforms
The hepatitis B surface antigen (HBsAg) is a multifunctional glycoprotein composed of large (LHB), middle (MHB), and small (SHB) subunits. HBsAg isoforms have numerous biological functions during HBV infection—from initial and specific viral attachment to the hepatocytes to initiating chronic infection with their immunomodulatory properties. Their immunogenic properties make them a major target for developing HBV vaccines, and they have been recognised as valuable targets for new therapeutic approaches. In addition, HBsAg isoform quantitation can become a useful non-invasive biomarker for assessing chronically infected patients.

Primary Care of the Person Living with HIV
HIV has transformed from an illness that resulted in one complication after another and nearly always resulted in death to a chronic illness that for most patients is more easily managed than diabetes or heart disease. Antiretroviral therapy (ART) is now simple and well-tolerated. The most important priority of HIV treatment is ensuring that people living with HIV stay on continuous, effective ART. ART, although not curative, suppresses the virus and allows the immune system to recover. Even when the CD4 count remains low, suppressive ART helps prevent opportunistic infections and other HIV related complications. Suppressive ART is important not only to the health of the individual living with HIV but is an important public health goal since people living with HIV will not transmit HIV to their sexual partners if their viral load is undetectable. A respectful, culturally appropriate patient–provider relationship is one of the most important factors in keeping people living with HIV engaged in care. Persons living with HIV deserve both excellent HIV and primary care. Some communities have providers that are experts in both, but often people living with HIV receive the best care by collaboration between their primary care provider and an HIV expert.

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.
