Skull Vibration Induced Nystagmus
Skull vibration induced nystagmus (SVIN) is a dramatic clinical observation—if a vibrator is applied to either mastoid of a patient with a total unilateral vestibular loss (TUVL) and switched on at a frequency of 100 Hz and at moderate intensity (about the strength a body massager) the patient immediately has a nystagmus, mainly horizontal, with the clinically obvious quick phases (QPs) beating away from the lesioned ear.

Contraceptive Use in the United States
Contraceptive use is deemed one of the 10 greatest public health achievements of the 20th century because its benefits are universally acknowledged as a cornerstone for reducing global maternal morbidity and mortality. Current data indicates gaps in contraceptive use patterns in the US, particularly among low-income women and those from racial/ethnic and gender minority subgroups, necessitating further investigation using an ecological approach.

Urban Green Space and Residents’ Mental Health
As an important part of urban built environment, urban green space has long been recognized in the fields of promoting residents’ mental health. The mediators can be divided into environmental factors, outdoor activity, and social cohesion. From the perspective of heterogeneity, both individual characteristics (e.g., age and gender) and group characteristics (e.g., level of urban development and urban density) of residents are considered to be the cause of various mediating effects. Types of urban green space tend to affect residents’ mental health through different paths.

Helminth Management
Understanding and managing the risk posed by helminth eggs (HE) is a key concern for wastewater engineers and public health regulators. The treatment processes that produce recycled water from sewage at wastewater treatment plants (WWTPs) rely on achieving a defined log10 reduction value (LRV) in HE concentration during the production of recycled water from sewage to achieve the guideline concentration of ≤1.0 HE/L.

Renin-Angiotensin System and COVID-19
The renin–angiotensin system (RAS), an essential enzymatic cascade involved in maintaining blood pressure and electrolyte balance, is involved in the pathogenicity of COVID-19, since the angiotensin-converting enzyme II (ACE2) acts as the cellular receptor for SARS-CoV-2 in many human tissues and organs. In fact, the viral entrance promotes a downregulation of ACE2 followed by RAS balance dysregulation and an overactivation of the angiotensin II (Ang II)–angiotensin II type I receptor (AT1R) axis, which is characterized by a strong vasoconstriction and the induction of the profibrotic, proapoptotic and proinflammatory signalizations in the lungs and other organs. This mechanism features a massive cytokine storm, hypercoagulation, an acute respiratory distress syndrome (ARDS) and subsequent multiple organ damage.

NAFLD Distribution
Non-alcoholic fatty liver disease (NAFLD) is considered the liver manifestation of metabolic syndrome. Nowadays, its prevalence is 25% worldwide and it is projected to reach the 30% in 2030, making NAFLD an important public health issue. NAFLD prevalence can vary according to the region and the social group under study. In fact, NAFLD distribution shows large inequalities by social group: Males have higher NAFLD prevalence, although if only postmenopausal women are taken into account, the prevalence is similar between genders. In the US, the Hispanic population has the highest NAFLD prevalence and African-American the lowest. Finally, higher NAFLD prevalence has been found among individuals with lower socioeconomic positions and food-insecure households.

Biopotential Signal Monitoring Systems in Rehabilitation
Rehabilitation consists of an iterative process involving assessments and specialized training, which unfortunately are often limited by healthcare centres’ restricted resources. To overcome this limitation, wearable technology should be an important, potential and valid solution to objectively assess and monitor patients inside and/or outside clinical environments. The information extracted by the use of this technology should provide a more detailed evaluation of the impairment, also allowing the identification of rehabilitation therapies.
