Lazarus Phenomenon
Autoresuscitation is a phenomenon of the heart during which it can resume its spontaneous activity and generate circulation. It was described for the first time by K. Linko in 1982 as a recovery after discontinued cardiopulmonary resuscitation (CPR). J.G. Bray named the recovery from death the Lazarus phenomenon in 1993. It is based on a biblical story of Jesus’ resurrection of Lazarus four days after confirmation of his death. Up to the end of 2022, 76 cases (coming from 27 countries) of spontaneous recovery after death were reported; among them, 10 occurred in children. The youngest patient was 9 months old, and the oldest was 97 years old. The longest resuscitation lasted 90 min, but the shortest was 6 min.

Vitamin D on Skeletal Muscle Dysfunction with COPD
Skeletal muscle dysfunction is frequently associated with chronic obstructive pulmonary disease (COPD), which is characterized by a permanent airflow limitation, with a worsening respiratory disorder during disease evolution. COPD is a progressive lung disease, characterized by an irreversible airflow limitation. In COPD, the pathophysiological changes related to the chronic inflammatory state affect oxidant–antioxidant balance, which is one of the main mechanisms accompanying extra-pulmonary comorbidity such as muscle wasting. Muscle impairment is characterized by alterations on muscle fiber architecture, contractile protein integrity, and mitochondrial dysfunction. Vitamin D deficiency affects oxidative stress and mitochondrial function influencing disease course through an effect on muscle function in COPD patients.

Childhood Socioeconomic Status and Adult Food Preference
Early childhood socioeconomic status (SES) conditions can influence how an adult responds to stress, their food preferences, the volume of food consumed, the likelihood that one will desire to eat in the absence of an energy deficit, the development of eating disorders, and the likelihood that one will suffer from adult obesity.

Vaccine versus Variants
With the emergence and spread of new SARS-CoV-2 variants, concerns are raised about the effectiveness of the existing vaccines to protect against these new variants. Although many vaccines were found to be highly effective against the reference COVID-19 strain, the same level of protection may not be found against mutation strains.

The Molecular Hydrogen Hypothesis
Since the late 18th century, molecular hydrogen (H2) has been shown to be well tolerated, firstly in animals, and then in humans. However, although research into the beneficial effects of molecular hydrogen in both plant and mammalian physiology is gaining momentum, the idea of utilising this electrochemically neutral and non-polar diatomic compound for the benefit of health has yet to be widely accepted by regulatory bodies worldwide. Due to the precise mechanisms of H2 activity being as yet undefined, the lack of primary target identification, coupled with difficulties regarding administration methods (e.g., dosage and dosage frequencies, long-term effects of treatment, and the patient’s innate antioxidant profile), there is a requirement for H2 research to evidence how it can reasonably and most effectively be incorporated into medical practice.

Mitochondrial and Sperm Physiology
Besides ATP production, mitochondria are key organelles in several cellular functions, such as steroid hormone biosynthesis, calcium homoeostasis, intrinsic apoptotic pathway, and the generation of reactive oxygen species (ROS). Despite the loss of the majority of the cytoplasm occurring during spermiogenesis, mammalian sperm preserves a number of mitochondria that rearrange in a tubular structure at the level of the sperm flagellum midpiece. Although sperm mitochondria are destroyed inside the zygote, the integrity and the functionality of these organelles seem to be critical for fertilization and embryo development.

Nutrition and Food Literacy in the MENA Region
Improving food and nutrition literacy is fundamental to tackling the Middle East and North Africa (MENA) region’s enormous challenges, including malnutrition and food insecurity. To direct initiatives, it is crucial to assess the region’s food and nutrition literacy. People in these countries mostly had inadequate food and/or nutrition literacy levels, especially in the skills rather than the cognitive domain. Food and/or nutrition literacy showed associations with food habits, food-label use, food-consumption patterns, school performance, food security, dietary diversity, and nutrient adequacy. The MENA countries developed no policies or programs to address food and nutrition literacy.

Side Effects and Efficacy of COVID-19 Vaccines
Coronavirus vaccines were well-tolerated, safe, and produced an immune response against the virus in most cases. Most postvaccine side effects were mild to moderate, which indicated the building of immunity by the body for protection.

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.

Parenting Programme
Parenting programmes are important ways to contribute to a healthy, sustainable, and resilient society. They benefit parents by reducing signs of stress and depression and increasing their self-efficacy and social behaviour, which leads to positive changes in childcare. In addition, they bring benefits to the parent–child relationship by relieving social pressure from parents, allowing a focus on the relationship with the child as an individual. Parenting programmes also positively affect society through knowledge sharing, networking, and support so that children can grow up in healthy environments and maximise their full potential.
