The impact of steatotic liver disease on coronary artery disease through changes in the plasma lipidome.

Steatotic liver disease has been shown to associate with cardiovascular disease independently of other risk factors. Lipoproteins have been shown to mediate some of this relationship but there remains unexplained variance. Here we investigate the plasma lipidomic changes associated with liver steatosis and the mediating effect of these lipids on coronary artery disease (CAD).

Mediating role of atherogenic lipoproteins in the relationship between liver fat and coronary artery calcification.

Non-alcoholic fatty liver disease (NAFLD) is associated with increased secretion of apoB-containing lipoproteins and increased risk of coronary heart disease (CHD). ApoB-containing lipoproteins include low-density lipoproteins (LDLs) and triglyceride-rich lipoproteins (TRLs); and since both LDLs and TRLs are causally related to CHD, they may mediate a portion of the increased risk of atherosclerosis seen in people with NAFLD. In a cohort of 4161 middle aged men and women, we performed mediation analysis in order to quantify the mediating effect of apoB-containing lipoproteins in the relationship between liver fat and atherosclerosis-as measured by coronary artery calcium score (CACS).

Femur Osteomyelitis and Associated Fracture as an Initial Presentation of Aortoenteric Fistula.

Aortoenteric fistula is a rare condition. Atypical presentations may cause significant management delays. We present the case of a 64-year-old male who experienced a pathological femoral fracture as an initial presentation of an underlying aortoenteric fistula.

Predicting Goal-directed Attention Control Using Inverse-Reinforcement Learning.

Understanding how goals control behavior is a question ripe for interrogation by new methods from machine learning. These methods require large and labeled datasets to train models. To annotate a large-scale image dataset with observed search fixations, we collected 16,184 fixations from people searching for either microwaves or clocks in a dataset of 4,366 images (MS-COCO).

Midterm experience of Scarf osteotomy as a new technique in a General Orthopaedic Department.

Scarf osteotomy has become popular as a versatile procedure that could correct most cases of hallux valgus. The purpose of this study is to report the experience with scarf osteotomy performed as a new technique by different surgeons of a general orthopaedic department. This study reviewed the outcome of 67 patients with 78 feet with hallux valgus deformity treated by scarf osteotomy at our institution, with an average follow-up of 24 months (12-84).

[Age related dehydroepiandrosterone decrease: clinical significance and therapeutic interest].

Dehydroepiandrosterone (DHEA) and its sulfate ester (DHEAS) are the most abundant steroids in humans, but their levels fall with age. This decrease has been associated with several age related diseases such as falls, osteoporosis, depression, atherosclerosis and sexual disorders. Moreover, studies have shown positive effects of DHEA administration on several of these disorders, with a satisfying safety profile.

Off-label use of hormones as an antiaging strategy: a review.

Given demographic evolution of the population in modern societies, one of the most important health care needs is successful aging with less frailty and dependency. During the last 20 years, a multitude of anti-aging practices have appeared worldwide, aiming at retarding or even stopping and reversing the effects of aging on the human body. One of the cornerstones of anti-aging is hormone replacement.

Pulmonary rehabilitation: the reference therapy for undernourished patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) combines the deleterious effects of chronic hypoxia, chronic inflammation, insulin-resistance, increased energy expenditure, muscle wasting, and exercise deconditioning. As for other chronic disorders, loss of fat-free mass decreased survival. The preservation of muscle mass and function, through the protection of the mitochondrial oxidative metabolism, is an important challenge in the management of COPD patients.

[Dementia prevention: potential treatments and how to target high risk patients].

The burden related to the ever-increasing dementia prevalence in older individuals, imposes the implementation of prevention strategies. It is now known that brain lesions related to Alzheimer's disease precede the onset of the first symptoms. Consequently, prevention strategies should be implemented early, before clinically overt dementia.

A review of age-related dehydroepiandrosterone decline and its association with well-known geriatric syndromes: is treatment beneficial?

Dehydroepiandrosterone (DHEA) and its sulfate ester are the most abundant steroids in humans. DHEA levels fall with age in men and women, reaching values sometimes as low as 10%-20% of those encountered in young individuals. This age-related decrease suggests an "adrenopause" phenomenon.

Effects of widely used drugs on micronutrients: a story rarely told.

Vitamins and trace elements are essential to the body, however, deficiencies are frequently observed in the general population. Diet is mostly responsible for these deficiencies but drugs also may play a significant role by influencing their metabolism. These effects are rarely assessed in clinical practice, in part because of limited data available in the literature.

A view of geriatrics through hormones. What is the relation between andropause and well-known geriatric syndromes?

Age related male hypogonadism, or "andropause", is increasingly recognized as of frequent occurrence in older patients. Diagnosis requires both the presence of clinical symptoms and low testosterone levels. However, diagnosing andropause in this age group may be challenging since symptoms are frequently non specific and testosterone levels are influenced by a multitude of parameters such as lifestyle factors and chronic diseases.

The Hospital Anxiety and Depression Scale: low sensitivity for depression screening in demented and non-demented hospitalized elderly.

Background: We currently use the depression subscale (HADD) of the Hospital Anxiety and Depression Scale (HADS) for depression screening in elderly inpatients. Given recent concerns about the performance of the HADD in this age group, we performed a quality-control study retrospectively comparing HADD with the diagnosis of depression by a psychiatrist. We also studied the effect of dementia on the scale's performance.

[The impact of medication on vitamins and trace elements].

Epidemiological studies have shown that vitamin or trace-element deficiencies are frequent in the general population. Food intake can be incriminated, but various drugs may also precipitate micronutrient deficits. Indeed, the consequences of pharmacotherapy on micronutrients are yet modestly explored in clinical practice settings.

Testosterone replacement therapy in reversing "andropause": what is the proof-of-principle?

Abstract Testosterone replacement therapy is often equated with the macho male physique and virility and is viewed by some as an antiaging tonic. The growth in testosterone's reputation and its increased use by men of all ages has seemed to outpace the scientific evidences. This review will aim to examine the uncertainty regarding the nature and the clinical importance of the age-related reduction in the testosterone levels.

Aging adults and seasonal influenza: does the vitamin d status (h)arm the body?

Vitamin D (VitD), although originally described as an essential hormone for bone and mineral homeostasis, appears to have an active role in regulating specific facets of human immunity. Indeed, VitD has been shown to have significant effects on cytokine production and lymphocyte proliferation. Evidence that VitD affects clearance of selected pathogens is supported by epidemiological and clinical data, while its coadministration with influenza vaccine in mice enhanced both mucosal and systemic antibody responses.

Comparison of the interobserver variability of 2 different methods of dietary assessment in a geriatric ward: a pilot study.

Background: Protein-energy malnutrition is highly prevalent in aged populations. Associated clinical, economic, and social burden is important. A valid screening method that would be robust and precise, but also easy, simple, and rapid to apply, is essential for adequate therapeutic management.

Delayed fracture of a zirconium head after total hip arthroplasty.

We present a case of fracture of a zirconium head after a cemented total hip arthroplasty. The fracture occurred 81 months after the index operation without any history of trauma. The patient was thin, not participating in sports, and the zirconium head had 0-mm neck length.
