Objective: To describe the etiologies of West syndrome (WS) among children followed in a rehabilitation center.

Method: Retrospective study with emphasis in the following items: gender, age at the diagnosis of WS and its etiology. The etiologies were divided into three categories: symptomatic, cryptogenic and idiopathic. Symptomatic cases were classified as follows: pre, post and perinatal.

Results: Ninety-five patients were included. Fifty-nine were boys (62%). Mean age at the diagnosis was 4.9 (+/- 5.0) months. There were 25 cryptogenic (26.3%), one idiopathic (1.1%) and 69 (72.6%) symptomatic cases, most of them of perinatal origin.

Conclusion: Our findings are in agreement with the literature. In the future, as our knowledge in the field of WS and its diagnostic methods increase, there will be a small number of cryptogenic and idiopathic cases.

Acanthamoeba spp. are widespread protists that feed on bacteria via phagocytosis. This predation pressure has led many bacteria to evolve strategies to resist and survive inside these protists.

Multiple Sclerosis (MS), a debilitating inflammatory disorder of the central nervous system characterized by demyelination, is significantly influenced by polygenic variations. Although the precise cause of MS remains unclear, it is believed to arise from a complex interplay of genetic and environmental factors. Recent investigations have focused on the polygenic nature of genetic alterations linked to MS risk.

Background: The pathogenesis of non-alcoholic fatty liver disease (NAFLD) with a global prevalence of 30% is multifactorial and the involvement of gut bacteria has been recently proposed. However, finding robust bacterial signatures of NAFLD has been a great challenge, mainly due to its co-occurrence with other metabolic diseases.

Results: Here, we collected public metagenomic data and integrated the taxonomy profiles with in silico generated community metabolic outputs, and detailed clinical data, of 1206 Chinese subjects w/wo metabolic diseases, including NAFLD (obese and lean), obesity, T2D, hypertension, and atherosclerosis.

Background: Abdominal aortic calcification (AAC) is considered as a strong predictor of cardiovascular disease (CVD) events. Our study aimed to investigate whether the predicted risk for cardiac death with the Framingham risk score (FRS) could be further improved with the addition of AAC score in general population aged ≥ 40 years.

Methods: A total of 2971 participants aged ≥ 40 years in the National Health and Nutrition Examination Surveys (NHANES) 2013-2014 were followed up.
