Pitfalls and Limitations of Glioblastoma Diagnosis and Follow-Up
Glioblastoma (GBM) is the most common and aggressive primary brain tumor. Glioblastoma is mainly diagnosed by neuroimaging techniques followed by histopathological and molecular analysis of the resected or biopsied tissue.

Psycho-Oncology
Psycho-oncology is an interdisciplinary field at the intersection of physical, psychological, social, and behavioral aspects of the cancer experience for both patients and caregivers. Also known as psychiatric oncology or psychosocial oncology, researchers and practitioners in the field are concerned with aspects of individuals' experience with cancer beyond medical treatment, and across the cancer trajectory, including at diagnosis, during treatment, transitioning to and throughout survivorship, and approaching the end-of-life. Founded by Jimmie Holland in 1977 via the incorporation of a psychiatric service within the Memorial Sloan Kettering Cancer Center in New York, the field has expanded drastically since and is now universally recognized as an integral component of quality cancer care. Cancer centers in major academic medical centers across the country now uniformly incorporate a psycho-oncology service into their clinical care, and provide infrastructure to support research efforts to advance knowledge in the field. Psycho-oncology deals with psychological reactions to the experience of cancer, the behavioral component of coping with cancer as well as health behavior change including preventive medicine, and social factors that are associated with diagnosis and treatment of cancer, including communication with providers and loved ones and social support. In addition, research related to the influence of psychosocial factors on biological disease-related processes has burgeoned over the past two decades. Much research takes a biopsychosocial approach to account for the interplay between biological, psychological, and social factors in coping with cancer. The integration of psycho-oncology into routine oncologic care represents a major step forward in terms of care for the whole patient.

The Mechanisms of Autism
Autism is a neurodevelopmental condition that starts in childhood and continues into adulthood. The core characteristics include difficulties with social interaction and communication, together with restricted and repetitive behaviours. There are a number of key abnormalities of brain structure and function that trigger these behavioural patterns, including an imbalance of functional connectivity and synaptic transmission, neuronal death, gliosis and inflammation. In addition, autism has been linked to alterations in the gut microbiome.

NRF2-Activating Compounds Bearing α,β-Unsaturated Moiety
The surge of scientific interest in the discovery of Nuclear Factor Erythroid 2 (NFE2)-Related Factor 2 (NRF2)-activating molecules underscores the importance of NRF2 as a therapeutic target especially for oxidative stress. The chemical reactivity and biological activities of several bioactive compounds have been linked to the presence of α,β-unsaturated structural systems. The α,β-unsaturated carbonyl, sulfonyl and sulfinyl functional groups are reportedly the major α,β-unsaturated moieties involved in the activation of the NRF2 signaling pathway. The carbonyl, sulfonyl and sulfinyl groups are generally electron-withdrawing groups, and the presence of the α,β-unsaturated structure qualifies them as suitable electrophiles for Michael addition reaction with nucleophilic thiols of cysteine residues within the proximal negative regulator of NRF2, Kelch-like ECH-associated protein 1 (KEAP1). The physicochemical property such as good lipophilicity of these moieties is also an advantage because it ensures solubility and membrane permeability required for the activation of the cytosolic NRF2/KEAP1 system.

Leishmaniases
The control of leishmaniases, a complex parasitic disease caused by the protozoan parasite Leishmania, requires continuous innovation at the therapeutic and vaccine levels. Thus, the classical drugs are toxic and generate drug resistance. These limitations are also the consequence of a non adapted biodistribution of the active principles. Chitosan is a biocompatible polymer administrable via different routes and possessing numerous qualities to be used in the antileishmanial strategies.

Energy Metabolism and Ketogenic Diets
It is well consolidated that a common mesenchymal cell progenitor shared by bone, skeletal muscle, and adipocytes cell progenitors exists. This makes the role of the skeleton in energy metabolism no longer surprising. Moreover, it also suggests that bone fragility could also be seen as a consequence of a “poor” quality in nutrition. Despite of the fact that ketogenic diet has been proven to be effective in epilepsy, long-term follow-up studies on epileptic children undergoing ketogenic diet reported an increased incidence of bone fractures and decreased bone mineral density too. However, the causes of such negative impacts on bone health have to be better defined. More recently, shorter-terms, or repeated cyclically for more or less short periods, KDs are used also in patients affected by T2DM, obesity, PCOS and so on. While possible correlations between KD and bone health were at least conceivable in children, it remains unclear whether the KD effects on bone health may be different in adults. Only few clinical studies have been adequately designed to investigate bone health are scarce and bone health related aspects, so far.  A narrative review on this issue, together practical advice on designing and implementing clinical studies on ketogenic nutritional regimens and bone health outcomes, is provided.

Drug Carriers for Arthritis Therapy
Drug carriers are used to penetrate the biological barriers and deliver the requisite active pharmaceutical ingredients (API). This has greater significance for medication in arthritis therapies because the inflammatory progression of rheumatoid arthritis (RA) and osteoarthritis (OA) is complex, intertwined, and influenced by one another. For this purpose, the drug delivery systems (DDS) of this carrier are currently being investigated with exogenous triggers and endogenous stimuli. This flexible-release invention will solve the problems of multiple implantations and local toxic accumulation at the lesion sites.

Applications of Artificial Intelligence for Palliative Care
Artificial intelligence (AI) model development for synthetic data generation to improve Machine Learning (ML) methodologies is an integral part of research in Computer Science and is currently being transferred to related medical fields, such as Systems Medicine and Medical Informatics. Palliative care (PC) uses a team-oriented approach to improve the quality of life of patients and their families who are facing problems associated with a life-threatening illness.

Creatine for Exercise/Sports Performance
Creatine is one of the most studied and popular ergogenic aids for athletes and recreational weightlifters seeking to improve sport and exercise performance, augment exercise training adaptations, and mitigate recovery time. Studies consistently reveal that creatine supplementation exerts positive ergogenic effects on single and multiple bouts of short-duration, high-intensity exercise activities, in addition to potentiating exercise training adaptations.
