Increasing plant protein in the diet induces changes in the plasma metabolome that may be beneficial for metabolic health. A randomized crossover study in males.

Background & Aim: Dietary shifts replacing animal protein (AP) with plant protein (PP) sources have been associated with lowering cardiometabolic risk (CMR), but underlying mechanisms are poorly characterized. This nutritional intervention aims to characterize the metabolic changes induced by diets containing different proportions of AP and PP sources in males at CMR.

Design: This study is a 4-week, crossover, randomized, controlled-feeding trial in which 19 males with CMR followed two diets providing either 36 % for the control diet (CON-D) or 64 % for the flexitarian diet (FLEX-D) of total protein intake from PP sources.

Multidimensional assessment of social cognition using non-immersive virtual reality in dementia with Lewy bodies and Alzheimer's disease: an exploratory study.

Introduction: Few studies have focused on social cognition in dementia with Lewy bodies (DLB), even though some brain structures being well known as underlying social cognitive processes are directly impacted in this disease. Furthermore, social cognition processes have been mostly studied independently using evaluations with poor ecological validity. We aimed at studying the ability of a new naturalistic and multidimensional social cognition task to reveal impairments in DLB patients.

[Good medicinal practice in epilepsy in the elderly].

Epilepsy is a frequent disease in the elderly. Diagnosis must be precise and systematic. Initiation of treatment must be assessed according to epileptic risk and comorbidities.

[Cerebral amyloid angiopathy and atrial fibrillation: anticoagulant dilemma].

Cerebral amyloid angiopathy and atrial fibrillation are two frequent comorbidities in older patients, leading to a therapeutic dilemma on the risk-benefit ratio of long-term anticoagulation. These patients both have a risk of cardioembolic complications due to atrial fibrillation, and a risk of cerebral haemorrhage from cerebral amyloid angiopathy. Since there is no therapeutic consensus, the best therapeutic strategy should be discussed during a multidisciplinary staff, based on four risk estimations: 1) the baseline risk of intracerebral haemorrhage without anticoagulation; 2) the risk of ischaemic stroke without anticoagulation; 3) the expected increase of intracerebral haemorrhage with anticoagulation; 4) the expected reduction in ischaemic stroke risk with anticoagulation.

[Pyoderma gangrenosum and hemopathies in older patients].

Pyoderma gangrenosum (PG) belongs to neutrophilic dermatoses. PG can have different clinical presentations (ulcerated, bullous, pustular), is often painful, and preferentially affects the lower limbs. The diagnosis can be challenging, and a cutaneous biopsy is often necessary, which shows an aseptic cutaneous infiltrate of neutrophils.

Prodromal characteristics of dementia with Lewy bodies: baseline results of the MEMENTO memory clinics nationwide cohort.

Background: Isolated subjective cognitive impairment (SCI) and mild cognitive impairment (MCI) are the prodromal phases of dementia with Lewy bodies (DLB). MEMENTO is a nationwide study of patients with SCI and MCI with clinic, neuropsychology, biology, and brain imaging data. We aimed to compare SCI and MCI patients with symptoms of prodromal DLB to others in this study at baseline.

Association between Vitamin D Deficiency and Prognosis after Hip Fracture Surgery in Older Patients in a Dedicated Orthogeriatric Care Pathway.

Objectives: Vitamin D deficiency is common in patients undergoing hip fracture surgery (HFS) and has been found to be associated with poor post-operative outcome in other settings. This study aimed to analyze the association between vitamin D status and prognosis after HFS.

Design: Observational, prospective, single-center study.

Evaluating the role of orange juice, HESPERidin in vascular HEALTH benefits (HESPER-HEALTH study): protocol for a randomised controlled trial.

Introduction: Although epidemiological studies associate the consumption of sugary beverages with adverse health effects, human experimental studies have demonstrated substantially different metabolic responses when 100% fruit juices are compared with artificial beverages. Fruit juices do not just provide sugars and associated calories, but they are also rich in bioactive compounds. Flavanones are bioactives specifically and abundantly found in citrus foods, with hesperidin as the major representative in sweet oranges.

[Confusional syndrome in the emergency room: from diagnosis to management].

Delirium is an emergency and can have serious consequences. On the arrival at the emergency room of an elderly person, it should be systematically checked for confusional syndrome. If it is confirmed, a systematic and rapid etiological assessment carried out in the emergency room allows the identification of predisposing and precipitating factors.

Fecal impaction is associated with postoperative urinary retention after hip fracture surgery.

Background: Postoperative urinary retention (POUR) is a common hip fracture (HF) complication. Although fecal impaction (FI) is one of the oft-cited causes of POUR in clinical practice, evidence regarding this association is scarce.

Objective: The aim of this study was to determine whether FI was associated with POUR after HF surgery in older patients.

FOXO3 targets are reprogrammed as Huntington's disease neural cells and striatal neurons face senescence with p16 increase.

Neurodegenerative diseases (ND) have been linked to the critical process in aging-cellular senescence. However, the temporal dynamics of cellular senescence in ND conditions is unresolved. Here, we show senescence features develop in human Huntington's disease (HD) neural stem cells (NSCs) and medium spiny neurons (MSNs), including the increase of p16 , a key inducer of cellular senescence.

Learning clinical networks from medical records based on information estimates in mixed-type data.

The precise diagnostics of complex diseases require to integrate a large amount of information from heterogeneous clinical and biomedical data, whose direct and indirect interdependences are notoriously difficult to assess. To this end, we propose an efficient computational approach to simultaneously compute and assess the significance of multivariate information between any combination of mixed-type (continuous/categorical) variables. The method is then used to uncover direct, indirect and possibly causal relationships between mixed-type data from medical records, by extending a recent machine learning method to reconstruct graphical models beyond simple categorical datasets.

Effects of Long-Term High-Fat Diet and Its Reversal on Lipids and Lipoproteins Composition in Thoracic Duct Lymph in Pigs.

BACKGROUND This study was carried out to evaluate the effects of a long-term high-fat diet on lipids and lipoproteins composition in thoracic duct lymph in pigs. MATERIAL AND METHODS We examined lymph taken from the thoracic duct from 24 female white sharp-ear pigs, divided into 3 experimental groups fed different diets for 12 months: (a) the control group, fed the standard balanced diet; (b) the HFD group, fed an unbalanced, high-fat diet, and (c) the reversal diet group (RD), fed an unbalanced, high-fat diet for 9 months and then a standard balanced diet for 3 months. RESULTS Lymph analysis after 12 months of fixed diets revealed significantly higher concentration of proteins in the HFD group in comparison to the control and RD groups.

Cognitive deficit, and neuropathological correlates, in the oldest-old.

Several disorders are usually involved in the cognitive deficit of the oldest old. Alzheimer disease is the commonest. It is usually characterized by progressive memory impairment - neocortical symptoms occurring much later in the course of the disease.

Multicenter phase III randomized trial comparing laparoscopy and laparotomy for colon cancer surgery in patients older than 75 years: the CELL study, a Fédération de Recherche en Chirurgie (FRENCH) trial.

Background: Several multicenter randomized controlled trials comparing laparoscopy and conventional open surgery for colon cancer have demonstrated that laparoscopic approach achieved the same oncological results while improving significantly early postoperative outcomes. These trials included few elderly patients, with a median age not exceeding 71 years. However, colon cancer is a disease of the elderly.

Simultaneous quantification of tau and α-synuclein in cerebrospinal fluid by high-resolution mass spectrometry for differentiation of Lewy Body Dementia from Alzheimer's Disease and controls.

Tau and α-synuclein are central in several neurodegenerative diseases, including Alzheimer Disease (AD), Dementia with Lewy Bodies (DLB) and Parkinson Disease (PD). New analytical methods for precise quantification of cerebrospinal fluid (CSF) levels of both tau and α-synuclein are required to differentiate between dementias or monitor therapeutic responses. Notably, levels of total α-synuclein reported by ELISA are inconsistent among studies, impacted by antibody specificity or lack of standardization.
