SARS-CoV-2 Spike Protein-Induced Dysfunction of the NRP-1/VEGF-A Complex
Long coronavirus disease-19 (COVID-19) is a newly discovered syndrome characterized by multiple organ manifestations that persist for weeks to months, following the recovery from acute disease. Occasionally, neurological and cardiovascular side effects mimicking long COVID-19 have been reported in recipients of COVID-19 vaccines. Hypothetically, the clinical similarity could be due to a shared pathogenic role of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spike (S) protein produced by the virus or used for immunization. The S protein can bind to neuropilin (NRP)-1, which normally functions as a coreceptor for the vascular endothelial growth factor (VEGF)-A. By antagonizing the docking of VEGF-A to NRP-1, the S protein could disrupt physiological pathways involved in angiogenesis and nociception. One consequence could be the increase in unbound forms of VEGF-A that could bind to other receptors. SARS-CoV-2-infected individuals may exhibit increased plasma levels of VEGF-A during both acute illness and convalescence, which could be responsible for diffuse microvascular and neurological damage.

Citrus Flavone Nobiletin and Circadian Rhythms
The importance of the circadian clock in maintaining human health is now widely acknowledged. Dysregulated and dampened clocks may be a common cause of age-related diseases and metabolic syndrome Thus, circadian clocks should be considered as therapeutic targets to mitigate disease symptoms.

PENG-Based Non-Invasive Medical Sensors
Piezoelectric nanogenerators (PENGs) not only are able to harvest mechanical energy from the ambient environment or body and convert mechanical signals into electricity but can also inform people about pathophysiological changes and communicate this information using electrical signals, thus acting as medical sensors to provide personalized medical solutions to patients.

Isoniazid Preventive Therapy for Tuberculosis among HIV Patients
Tuberculosis (TB) is a major cause of morbidity and mortality in people living with HIV (PLWHIV). Isoniazid preventive therapy (IPT) prevents TB in PLWHIV, but estimates of its effects and actual implementation vary across countries. PLHIV who were on IPT, independently or simultaneously with ART, were less likely to develop TB than those without IPT. IPT interventions had a significant association with improved CD4 count and reduced all-cause mortality. IPT was less effective in people with advanced HIV infection. The major factors influencing IPT implementation and uptake were stock-outs, fear of developing isoniazid-resistant TB, patient’s refusal and non-adherence, and improper counseling and low commitment of HIV clinical care providers. IPT alone or in combination with ART significantly reduces the incidence of TB and mortality in PLHIV in Ethiopia than those without IPT. More research on safety is needed, especially on women with HIV who receive a combination of IPT and ART.

Genetic Polymorphisms as Biomarkers of Susceptibility
A clean environment is fundamental to human health and well-being. However, environment can be a souce of  various stressors, such as bad quality of air, pollution, noise and hazardous substances affecting our health.The human health is also influenced by climate change, producing flood, heatwaves and presence of vector-borne disease affecting the global health. The climate changes, loss of biodiversity loss and land degradation contribute to impact the human well-being. Human health is influenced by various factors; these include genetic inheritance, behavioral lifestyle, socioeconomic and environmental conditions, and public access to care and therapies in case of illness, with the support of the national health system. All these factors represent the starting point for the prevention and promotion of a healthy lifestyle. However, it is not clear to what extent these factors may actually affect the health of an entire population. The exposures to environmental and occupational factors are several, most of which might be poorly known, contributing to influencing the individual health. Personal habits, including diet, smoking, alcohol, and drug consumption, together with unhealthy behaviors, may inevitably lead people to the development of chronic diseases, contributing to increase aging and decrease daily life expectancy. Despite such risks, humans should modify the bad habits in favour of virtuous habits.

Sustainable Health Care Provision Worldwide
Quality health care is an essential human right, on the agenda of sustainable development and presents a challenge in the twenty-first century. There are different perspectives regarding the price and quality of health care, and it is necessary to review the quality health care issue and how it influenced by price. Health care is a service industry, needs basic standards and specialized human resources to perform the procedure, and quality health care is not associated with an extra price. The quality of health care assures sustainability. Likewise, there are some additional choices during certain procedures, and those may have different price options and would be linked with quality. So, those optional health care and basic health need to define separately.

Methylmercury, DNA, and Chromatin
Methylmercury (MeHg) is an environmental neurotoxin that can adversely affect the development of the nervous system. The molecular integrity of chromatin in the nucleus is an important target of MeHg. Low levels of MeHg trigger epigenetic mechanisms that may be involved in long-lasting and transgenerational neurotoxicity after exposure. Emerging evidence has shown that these mechanisms include histone modification, short interfering RNA (siRNA), and DNA methylation.

Heart Failure with Preserved Ejection Fraction
Heart failure with preserved ejection fraction (HFpEF) remains a poorly characterized syndrome with many unknown aspects related to different patient profiles, various associated risk factors and a wide range of aetiologies. It comprises several pathophysiological pathways, such as endothelial dysfunction, myocardial fibrosis, extracellular matrix deposition and intense inflammatory system activation.

Digital Twins for Home Remote Motor Rehabilitation
The COVID-19 pandemic created the need for telerehabilitation development, while Industry 4.0 brought the key technology. As motor therapy often requires the physical support of a patient’s motion, combining robot-aided workouts with remote control is a promising solution. This may be realised with the use of the device’s digital twin so as to give it an immersive operation. Such technology may be used for manual remote kinesiotherapy, combined with the safety systems predicting potentially harmful situations. The concept is universally applicable to rehabilitation robots.
