Background: The COVID-19 pandemic has impacted the lives of individuals, families, and children worldwide. In Italy, the implementation of measures such as lockdowns and distance learning in schools affected the mental health of children and families. Methods: This article employs a qualitative method to explore the efficacy of a death education project that aimed to help primary school children process the emotions and losses that they experienced during the COVID-19 pandemic. The study encompassed both the children who took part in the death education project and their teachers and parents to investigate their perspectives on the emotions of the minors and the effectiveness of the project. Results: Distance learning posed challenges for the learning process and exacerbated social inequalities. The children suffered from limited social contact with their friends and experienced negative emotions, including anger, fear, and concern for the health of their loved ones. The death education project provided a safe space for children’s emotional expression and facilitated their acquisition of coping strategies. Open communication between adults and children about illness and death proved effective in mitigating the psychological impacts of loss and preventing traumatic bereavement. Conclusion: The findings highlight the utility of death education in enhancing children’s ability to express their emotions and approach the topic of death more frankly.

This study employs a qualitative methodology to explore the effects of the pandemic on the lives of ALS patients and their caregivers. It aims to understand whether and how online self-help groups have assisted families dealing with amyotrophic lateral sclerosis (ALS) patients. ALS is a neurodegenerative disease with both physical and psychosocial implications. Consequently, it significantly affects the lives of patients’ caregivers. In 2020, the COVID-19 pandemic exacerbated this situation. The results show that the pandemic has had a negative impact on the well-being of ALS caregivers and patients. Furthermore, bereavement and death were dealt with in different ways by the families involved. The pandemic aggravated the health of ALS patients and increased the workload of their caregivers; however, online psychological support was appreciated for its role in providing emotional help and diminishing social isolation.

Amongst other approaches, adipose-derived stromal cells (ASCs) have recently been tested with respect to their regenerative capacity for treatment of neuromuscular disorders. While beneficial effects of ASCs on muscle recovery were observed previously, their impact on regeneration of neuromuscular junctions (NMJs) is unclear. Here, we used a murine glycerol damage model to study disruption and regeneration of NMJs and to evaluate the effects of systemic application of ASCs on muscle and NMJ recovery. In mice that were not treated with ASCs, a differential response of NMJ pre- and post-synapses to glycerol-induced damage was observed. While post-synapses were still present in regions that were necrotic and lacking actin and dystrophin, pre-synapses disappeared soon in those affected areas. Partial regeneration of NMJs occurred within 11 days after damage. ASC treatment slightly enhanced NMJ recovery and reduced the loss of presynaptic sites, but also led to a late phase of muscle necrosis and fibrosis. In summary, the results suggest a differential sensitivity of NMJ pre- and post-synapses to glycerol-induced muscle damage and that the use of ASC for the treatment of neuromuscular disorders needs further careful evaluation.

Neuromuscular junctions (NMJs) mediate skeletal muscle contractions and play an important role in several neuromuscular disorders when their morphology and function are compromised. However, due to their small size and sparse distribution throughout the comparatively large, inherently opaque muscle tissue the analysis of NMJ morphology has been limited to teased fiber preparations, longitudinal muscle sections, and flat muscles. Consequently, whole mount analyses of NMJ morphology, numbers, their distribution, and assignment to a given muscle fiber have also been impossible to determine in muscle types that are frequently used in experimental paradigms. This impossibility is exacerbated by the lack of optical tissue clearing techniques that are compatible with clear and persistent NMJ stains. Here, we present MYOCLEAR, a novel and highly reproducible muscle tissue clearing protocol. Based on hydrogel-based tissue clearing methods, this protocol permits the labeling and detection of all NMJs in adult hindleg extensor digitorum longus muscles from wildtype and diseased mice. The method is also applicable to adult mouse diaphragm muscles and can be used for different staining agents, including toxins, lectins, antibodies, and nuclear dyes. It will be useful in understanding the distribution, morphological features, and muscle tissue context of NMJs in hindleg muscle whole mounts for biomedical and basic research.
