ABSTRACT

The post-COVID condition (PCC) is a pathology stemming from COVID-19, and studying its pathophysiology, diagnosis, and treatment is crucial. Neuroinflammation causes the most common manifestations of this disease including headaches, fatigue, insomnia, depression, anxiety, among others. Currently, there are no specific management proposals; however, given that the inflammatory component involves cytokines and free radicals, these conditions must be treated to reduce the current symptoms and provide neuroprotection to reduce the risk of a long-term neurodegenerative disease. It has been shown that cannabis has compounds with immunomodulatory and antioxidant functions in other pathologies. Therefore, exploring this approach could provide a viable therapeutic option for PCC, which is the purpose of this review. This review involved an exhaustive search in specialized databases including PubMed, PubChem, ProQuest, EBSCO, Scopus, Science Direct, Web of Science, and Clinical Trials. Phytocannabinoids, including cannabidiol (CBD), cannabigerol (CBG), and Delta-9-tetrahydrocannabinol (THC), exhibit significant antioxidative and anti-inflammatory properties and have been shown to be an effective treatment for neuroinflammatory conditions. These compounds could be promising adjuvants for PCC alone or in combination with other antioxidants or therapies. PCC presents significant challenges to neurological health, and neuroinflammation and oxidative stress play central roles in its pathogenesis. Antioxidant therapy and cannabinoid-based approaches represent promising areas of research and treatment for mitigating adverse effects, but further studies are needed.

ABSTRACT

Patients with Parkinson's disease (PD) have cognitive deficits that cause functional impairments across several domains, including language. There is experimental evidence that basal ganglia and frontostriatal circuits are implicated in phonological processing, which leads to the hypothesis that a dysfunction of these circuits could be expressed behaviorally as phonological deficiencies in patients with PD. Using neuropsychological assessments, the present study aimed to explore the phonological processing abilities of patients in the initial stages of PD while controlling for other cognitive processes. The results showed lower scores in patients with PD on phonological tests with respect to a control group and these differences were independent of processes such as attention/working memory, long-term memory, thinking, and verbal language comprehension. However, there was an association between phonological skills and reading comprehension abilities. This finding implies a specific phonological deficit in terms of word reading.

ABSTRACT

Se analizaron 5,169 gasometrías arteriales mediante el cálculo de concordancia, brecha aniónica, cálculo de respuesta compensatoria esperada y de gradiente alvéolo-arterial de oxígeno. Se revisaron además 400 expedientes clínicos para establecer si la información obtenida se incluyó en los mismos. Se encontró que 424 (8 por ciento) gasometrías no fueron interpretadas por carecer de concordancia entre sus valores. Los servicios que más solicitaron el estudio fueron terapia intensiva, pediatría y urgencias de adultos. Las indicaciones más comunes fueron problemas metabólicos asociados a diabetes mellitus, insuficiencia renal y cirrosis. El trastorno ácido-básico más frecuente fue la alcalemia por acidosis metabólica y alcalosis respiratoria asociada a diabetes mellitus e insuficiencia crónica. Los demás trastornos ácido-básicos simples y complejos son poco frecuentes. Se encontraron 661 (13.9 por ciento) gasometrías normales, lo que sugiere que el médico indica adecuadamente el estudio. De los 400 expedientes clínicos revisados sólo en 10 (2.5 por ciento) se realizó una adecuada interpretación, lo que muestra que la gasometría arterial es un recurso subutilizado. La causa más frecuente de hipoxemia con gradiente alvéolo-arterial de oxígeno amplio fue la enfermedad broncopulmonar obstructiva crónica. Hipoxemia con gradiente alvéolo-arterial de oxígeno normal se asoció con enfermedad cerebrovascular. Se concluye que la gasometría arterial es un estudio confiable, generalmente bien indicado pero pobremente evaluado y esto hace que información valiosa se pierda

ABSTRACT

Helicobacter pylori es quizá la infección bacteriana crónica más frecuente en el mundo. Se calcula que hasta un 50 por ciento de la población puede esta infectada, cifra que alcanza 100 por ciento en poblaciones con escasas condiciones sanitarias. El espectro clínico de la enfermedad es amplio, abarca desde la gastritis y úlcera péptica hasta el cáncer gástrico, pasando por asociaciones menos claras, como enfermedad coronaria, rosácea y retraso del crecimiento en niños. Los mecanismos fisiopatológicos responsables apenas se comienzan a comprender, modificando el antiguo concepto de ®no ácido, no úlcera¼, que aunque aún es válido, no es suficiente. Por lo anterior, tiene suma importancia establecer la presencia del germen y proporcionar el tratamiento correcto
