Article Synopsis
  • PCSK9 is crucial for regulating LDL-cholesterol and certain variants, like p.Ser127Arg, lead to higher cholesterol levels and are mainly found in France, with few in South Africa and Norway due to a common ancestor effect.
  • The study analyzed 14 p.Ser127Arg carriers from eight families and compared them with other variants to understand their genetic background and health impact.
  • Results indicated that the common ancestor lived about 775 years ago, and carriers of p.Ser127Arg had significantly higher LDL-C levels, suggesting it may have a stronger effect on cholesterol levels compared to other mutations.

Background: Heterozygous familial hypercholesterolemia (HeFH) predisposes to premature cardiovascular diseases. Since 2015, the European Atherosclerosis Society has advocated initiation of statins at 8-10 years of age and a low-density lipoprotein cholesterol (LDL-C) target of <135 mg/dL. Longitudinal data from large databases on pharmacological management of pediatric HeFH are lacking.

Despite years of study and major research advances over the past 50 years, atherosclerotic diseases continue to rank as the leading global cause of death. Accumulation of cholesterol within the vascular wall remains the main problem and represents one of the early steps in the development of atherosclerotic lesions. There is a complex relationship between vesicular cholesterol transport and atherosclerosis, and abnormalities in cholesterol trafficking can contribute to the development and progression of the lesions.

Introduction: Bariatric surgery can become technically challenging in the setting of liver steatosis and hepatomegaly. The protein sparing modified fast (PSMF) diet helps in achieving rapid weight loss. The aim of this study is to explore the results of a preoperative PSMF diet on liver volume and steatosis as well as on intraoperative and postoperative complications in patients with hepatomegaly undergoing Roux-en-Y gastric bypass (RYGB).

Objective: To identify childhood and parental factors associated with initiation of statin therapy in children with heterozygous familial hypercholesterolemia (HeFH), including underlying genetic diagnosis or parental premature atherosclerotic cardiovascular disease (ASCVD).

Study Design: This multicenter cohort study included 245 HeFH child-parent pairs from the REFERCHOL national register (2014-2020). Demographic and clinical characteristics at the last visit were collected.

We report 3 cases of spontaneous intracranial hypotension (SIH) associated with consciousness disorder and coma. In patients, SIH was suspected on a computed tomography scan and diagnosed by cerebral magnetic resonance imaging (MRI). Spinal MRI confirmed cerebrospinal fluid leakage.

Background: Most guidelines recommend a systematic screening of asymptomatic high risk patients with diabetes for silent ischemia, but the clinical benefit of this strategy has not been demonstrated compared with the simple control of cardiovascular risk factors. We sought to determine whether referring asymptomatic diabetic patients for screening of silent ischemia decreases the risk of cardiovascular events compared with usual care.

Methods: DYNAMIT was a prospective, randomized, open, blinded end-point multicenter trial run between 2000 and 2005, with a 3.

Chronic diseases such as obesity, diabetes, macrovascular disease including coronaropathy and stroke, osteoporosis and various cancer have, in one way or another, food and nutritional determinants and may be considered as nutritionally or environmental-related diseases. There is a growing literature indicating that specific dietary constituents or diet are able to influence the development and the outcome of chronic disease. Long term prospective clinical trials are yet locking to confirm on evidences-based medicine criteria the correlation described between food and disease.

Hyperglycemia is commun in critically ill patients without previously known diabetes. Hyperglycemia occurring in these patients is mainly a consequence of stress associated to complex glucose metabolism abnormalities which have deleterious effects on tissues and vascular function. Several epidemiologic and intervention studies had established that hyperglycemia is related to morbidity and mortality.
