Abusive use of Zolpidem as a Result of COVID-19 and Perspectives of Continuity of the Problem in the Post-Pandemic Period.

Zolpidem is a non-benzodiazepine hypnotic drug that works as a positive modulator of Gamma-Amino Butyric Acid-A (GABA-A) receptors, with high selectivity for α1 subunits. Given this selective binding, the drug has a strong hypnotic activity. Social isolation during the SARS-CoV-2 pandemic has contributed to increased rates of anxiety, depression, and insomnia. As a result, studies have pointed to a possible increase in the indiscriminate use of drugs with sedative effects, such as Zolpidem, during the pandemic. The aim of this work was to present prospective evidence that warns of the possibility of the abusive use of Zolpidem even after the pandemic. High rates of addiction to this drug have been reported around the world after the emergence of the coronavirus. Data from the National Survey on Drug Use and Health and from Medicaid support the continuing growth in prescription and indiscriminate use of Zolpidem during the pandemic and afterward. Therefore, there is enough evidence to support the indiscriminate use of this drug since the beginning of the pandemic. Rates of indiscriminate use of sedatives may continue to increase in the post-pandemic period, especially if strict control measures are not taken by health authorities.

S100 proteins and their implication in the thalamus: an integrative review / Las proteínas S100 y su implicación en el tálamo: una revisión integradora

SUMMARY: S100 proteins belong group of calcium-binding proteins and are present in physiological intracellular and extracellular regulatory activities, such as cell differentiation, and act in inflammatory and neoplastic pathological processes. Recently, its expressions in the nervous system have been extensively studied, seeking to elucidate its action at the level of the thalamus: A structure of the central nervous system that is part of important circuits, such as somatosensory, behavioral, memory and cognitive, as well as being responsible for the transmission and regulation of information to the cerebral cortex. This article is an integrative review of scientific literature, which analyzed 12 studies present in Pubmed. The analysis showed that the relationship of S100 proteins and the thalamus has been described in neoplastic processes, mental disorders, hypoxia, trauma, stress, infection, Parkinson's disease and epilepsy. In summary, it is possible to conclude that this protein family is relevant as a marker in processes of thalamic injury, requiring further studies to better understand its clinical, preclinical meanings and its prognostic value.

Las proteínas S100 pertenecen al grupo de proteínas fijadoras de calcio y están presentes en actividades reguladoras fisiológicas intracelulares y extracelulares, como la diferenciación celular, y actúan en procesos patológicos inflamatorios y neoplásicos. Recientemente, sus expresiones en el sistema nervioso han sido ampliamente estudiadas, buscando dilucidar su acción a nivel del tálamo: una estructura del sistema nervioso central que forma parte de importantes circuitos, como el somatosensorial, conductual, de memoria y cognitivo, así como además de ser responsable de la transmisión y regulación de la información a la corteza cerebral. Este artículo es una revisión integradora de la literatura científica, que analizó 12 estudios presentes en Pubmed. El análisis mostró que la relación de las proteínas S100 y el tálamo ha sido descrita en procesos neoplásicos, trastornos mentales, hipoxia, trauma, estrés, infección, enfermedad de Parkinson y epilepsia. En resumen, es posible concluir que esta familia de proteínas es relevante como marcador en procesos de lesión talámica, requiriendo más estudios para comprender mejor su significado clínico, preclínico y su valor pronóstico.

Clinical profile and quality of life in climacteric women.

BACKGROUND: The Quality of Life in climacteric women is intrinsically related to signs and symptoms influenced by the decrease of estrogen and psychosocial factors linked to the natural aging process. Thus, this study aimed to trace the sociodemographic and clinical profiles of climacteric women working at the State University of Rio Grande do Norte (UERN) and evaluate their Quality of Life. METHODS: It is a descriptive, exploratory, and quantitative study. The population consisted of female workers from UERN, aging between 40 and 65 years. The total sample consisted of 63 women who answered the forms. Data collection was completely online, which allowed the women to have free choice to choose the most appropriate time to answer the questions. RESULTS: The majority of the participants were older than 50 years (53.97%, n = 34), were married or in a stable union (55.56%, n = 35), and lived in Mossoró-RN (82.53%, n = 52). Regarding skin color, white and brown women had the same percentage of 44.44% (n = 28). The pain, general health status, and vitality domains evidence the predominance of poor quality of life in the SF-36 questionnaire. Regarding the level of satisfaction with their current health status, 4.76% (n = 3) stated that they fit the level considered excellent, 44.44% (n = 28) very good, 46, 03% (n = 29) were good, and 4.77% (n = 3) stated unsatisfied with their current health status. The intensity of symptoms related to estrogen deficiency established by the Kupperman menopause index is as Mild 55.56% (n = 35), moderate 41.27% (n = 26), and severe 3.17% (n = 2). CONCLUSIONS: The occurrence of symptoms and perception of these symptoms differs from woman to woman, to a greater or lesser extent. These findings emphasize the need for qualified and individualized care for the needs of these women in health services and the development of applicable solutions for solving problems based on each woman profile.

Experimental considerations concerning the use of stem cells and tissue engineering for facial nerve regeneration: a systematic review.

PURPOSE: Peripheral nerve trauma results in functional loss in the innervated organ, and recovery without surgical intervention is rare. Many surgical techniques can be used for repair in experimental models. The authors investigated the source and delivery method of stem cells in experimental outcomes, seeking to clarify whether stem cells must be differentiated in the injured facial nerve and improve the regenerative process. MATERIALS AND METHODS: The following key terms were used: nervous regeneration, nerve regeneration, facial nerve regeneration, stem cells, embryonic stem cells, fetal stem cells, adult stem cells, facial nerve, facial nerve trauma, and facial nerve traumatism. The search was restricted to experimental studies that applied stem cell therapy and tissue engineering for nerve repair. RESULTS: Eight studies meeting the inclusion criteria were reviewed. Different sources of stem and precursor cells were explored (bone marrow mesenchymal stem cells, adipose-derived stem cells, dental pulp cells, and neural stem cells) for their potential application in the scenario of facial nerve injuries. Different material conduits (vases, collagen, and polyglycolic acid) were used as bridges. Immunochemistry and electrophysiology are the principal methods for analyzing regenerative effects. Although recent studies have shown that stem cells can act as a promising bridge for nerve repair, considerable optimization of these therapies will be required for their potential to be realized in a clinical setting. CONCLUSION: Based on these studies, the use of stem cells derived from different sources presents promising results related to facial nerve regeneration and produces effective functional results. The use of tubes also optimizes nerve repair, thus promoting greater myelination and axonal growth of peripheral nerves.
