NK Cells—the Immune System against Glioblastoma
Glioblastoma (GBM) is the primary cancer with the highest incidence within the central nervous system. Natural killer (NK) cells are innate lymphocytes that play an important role in immunosurveillance, acting alongside other immune cells in the response against various types of malignant tumors and the prevention of metastasis. NK cells are being exploited in many ways to treat cancer. The broad arsenal of NK-based therapies includes adoptive transfer of in vitro expanded and activated cells, genetically engineered cells to contain chimeric antigen receptors (CAR-NKs), in vivo stimulation of NK cells (by cytokine therapy, checkpoint blockade therapies, etc.), and tumor-specific antibody-guided NK cells, among others.

Climate Change and Child Health Inequality
Geographical location, socioeconomic resources and intergenerational differences were explored as dimensions of inequality with regard to the increased risk of adverse health outcomes among children resulting from climate change. Definitions and descriptions of climate change and of child health in the reviews were explored as secondary themes.

Resistance Training: Intensity and Volume
Resistance training is a form of exercise that can increase or maintain muscle mass and muscle strength, which helps older adults preserve their independence and quality of life. It can overcome the loss of muscle mass and strength, build resilience, ease the management of chronic conditions, and reduce physical vulnerability. Resistance training can be done in several ways depending on the physiological and functional or performance goals. The different trainable characteristics of the neuromuscular system include strength, endurance, power, muscle hypertrophy, and motor performance. A list of resistance training types for practical resistance training in older adults is presented below, pointing out intensity and volume.

Comparison of Different Food Classification Systems
The technological developments and the rise in highly processed food availability have introduced the concept of ultra-processed food (UPF). Food classification systems based on processing are now a new basis for epidemiological research. Different results from these classifications might influence conclusions on the population’s consumption of UPF or its association with health outcomes.

Long-Term Effects of Human Papillomavirus Vaccination
The preventive effect of Human papillomavirus (HPV) vaccines against anogenital and oropharyngeal cancers has been proven in both clinical trials and real-world data. The longest period of preventive effect for the bivalent, 4-valent, and 9-valent vaccine were 11 years in the Costa Rica trial, 14 years in the FUTURE II, and 8 years in the LTFU extension study of V503-002 and the Scandinavian study, respectively. The sustained clinical effect during the observation period was longest for the 4-valent vaccine. In real-world data, the longest observation period of the vaccine effectiveness was 12 years in an Australian study for the 4-valent vaccine. For the bivalent vaccine, additional long-term follow-up studies may not have been planned due to the launch of the 4-valent and 9-valent vaccines. In some studies of the 9-valent vaccine, the results have not yet been published because of the short observation period. The additional results are expected in the future. In a national immunization program, most girls and boys are inoculated with HPV vaccine by the time puberty begins; thus, it is important to monitor the vaccine effect at least until the sexually active period in their 20s and 30s.

COVID-19 and Adolescents’ Sexual/Reproductive Health in Low-/Middle-Income Countries
There are various aspects of adolescents’ sexual and reproductive health that were highly impacted due to the COVID-19 pandemic. These include limited access to sexual and reproductive health services, including access to contraceptives, menstrual products, and medications for HIV treatment; increased rates of early marriage due to school closures and a lack of support from school management; a rise in intimate partner and sexual violence; disruptions in maternity care; and increased involvement of adolescents in risky or exploitative work.

Cryptococcus neoformans
Cryptococcus neoformans var. neoformans is the second most prevalent agent of cryptococcosis in central Europe. Infections mostly present with localized skin and disseminated infections. Clinical isolates of C. neoformans var. neoformans present a substantial phenotypic variability. Median survival of G. mellonella varied between 6 and 14 days. C. neoformans var. neoformans isolates from disseminated infections showed stronger melanization and larger capsules.

Palatal Rugae Pattern after Orthodontic Treatment
Palatal rugae are the irregular connective tissue also known as “plicae palatinae. These are anatomical folds located posterior to the incisive papilla in the palatal anterior third. These folds, which form as early as 3 months in utero, are largely attributed to the hardened connective tissue that covers the bone. Their orientation and pattern are formed in the fourth month of intrauterine life. Their uniqueness lies in the fact that they are stable and show post-mortem resistance until oral mucosal degeneration after death . Their anatomical location on the internal aspect of the oral cavity protects them from different environmental factors including rising temperature, palatal infections, trauma, and tooth exfoliation and eruption. They are considered suitable landmarks for forensic identification.

Consanguinity and Congenital Heart Disease Susceptibility
Congenital heart disease (CHD) encompasses a wide range of structural defects of the heart and, in many cases, the factors that predispose an individual to disease are not well understood, highlighting the remarkable complexity of CHD etiology. Evidence of familial aggregation of CHD has been demonstrated in different communities and for different cardiac lesions. Consanguinity, particularly among first cousins, is an added risk factor for these families, particularly in societies where it is considered a common cultural practice, as confirmed in previous studies conducted in Saudi Arabia and other countries.

Upper Airway Changes in Diverse Orthodontic Looms
Upper airway assessment is particularly important in the daily work of orthodontists, because of its close connection with the development of craniofacial structures and with other pathologies such as Obstructive Sleep Apnea Syndrome (OSAS). Rapid maxillary expansion and surgical advancement for the correction of Class II patients are associated with significant improvement in the upper airway, whereas maxillary protraction, extraction therapy, orthognathic surgery for Class III, and the use of a functional appliance have no significant impact.
