Background A connection between amyotrophic lateral sclerosis (ALS) and altered gut microbiota composition has previously been reported in animal models. This work is the first prospective longitudinal study addressing the microbiota composition in ALS patients and the impact of a probiotic supplementation on the gut microbiota and disease progression. Methods Fifty patients and 50 matched controls were enrolled. The microbial profile of stool samples from patients and controls was analyzed via PCR-Denaturing Gradient Gel Electrophoresis, and the main microbial groups quantified via qPCR. The whole microbiota was then analyzed via next generation sequencing after amplification of the V3-V4 region of 16S rDNA. Patients were then randomized to receive probiotic treatment or placebo and followed up for 6 months with ALSFRS-R, BMI, and FVC%. Results The results demonstrate that the gut microbiota of ALS patients is characterized by some differences with respect to controls, regardless of the disability degree. Moreover, the gut microbiota composition changes during the course of the disease as demonstrated by the significant decrease in the number of observed operational taxonomic unit during the follow-up. Interestingly, an unbalance between potentially protective microbial groups, such as Bacteroidetes, and other with potential neurotoxic or pro-inflammatory activity, such as Cyanobacteria, has been shown. The 6-month probiotic treatment influenced the gut microbial composition; however, it did not bring the biodiversity of intestinal microbiota of patients closer to that of control subjects and no influence on the progression of the disease measured by ALSFRS-R was demonstrated. Conclusions Our study poses the bases for larger clinical studies to characterize the microbiota changes as a novel ALS biomarker and to test new microbial strategy to ameliorate the health status of the gut.

In this paper, we demonstrate the development and optimization of two direct DNA-based quantitative real-time PCR assays using species-specific oligonucleotide primer pairs derived from rpoB and gyrA genes for A. faecis and A. lanthieri, respectively. Initially, the specificity of primers and amplicon size of each target reference strain was verified and confirmed by melt curve analysis. Standard curves were developed with a minimum quantification limit of 100 cells mL- 1 or g- 1 obtained using known quantities of spiked A. faecis and A. lanthieri reference strains in autoclaved agricultural surface water and dairy cow manure samples. Results Each species-specific qPCR assay was validated and applied to determine the rate of prevalence and quantify the total number of cells of each target species in natural surface waters of an agriculturally-dominant and non-agricultural reference watertal samples.Background Apolipoprotein E (APOE) is involved in the pathogenesis of atherosclerosis and conveys a higher risk of coronary artery disease (CAD). find more The aim of the present study was to investigate the possible association between APOE gene polymorphism and the risk of CAD in postmenopausal Hakka women in southern China. Methods The APOE genotypes of 653 CAD patients and 646 control participants were determined by the polymerase chain reaction (PCR) and hybridization to a Sinochip. Results The prevalence of each APOE genotype differed between CAD patients and control participants (P = 0.011). The E3/E3 genotype was the most common and the E2/E2 genotype was the least common in the study sample. Moreover, the presence of ε4 allele was associated with higher serum concentrations of triglycerides (TG), total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C), and lower concentration of high-density lipoprotein-cholesterol (HDL-C). Multiple logistic regression analysis revealed that participants with ε4 allele have a significantly higher risk of CAD after adjustment for the presence of diabetes mellitus and hypertension, and their serum uric acid, TC, and LDL-C concentrations (adjusted odds ratio (OR) 1.50, 95% confidence interval (CI) 1.10-2.05, P = 0.010). Conclusions The present results suggest that APOE polymorphism is associated with a higher risk of CAD in postmenopausal Hakka women in southern China.Background Patients with metastatic small-intestinal neuroendocrine tumours (NET) have been shown to have a reduced quality of life compared to the general population and many have disabling symptoms during somatostatin analogue (SSA) treatment. The aim of this prospective study was to document the patient-reported symptoms, coping and quality of life during SSA treatment and to measure patients' fat-soluble vitamin levels. Methods Patients with metastatic small-intestinal NET on treatment with long-acting SSA were included. Data on patient characteristics, blood samples, questionnaires (EORTC-QLQ-C30 and GI.NET-21) and structured patient interviews were collected at inclusion and after 1 year. Results Eighty-eight patients were included, 77 (88%) attended 1 year follow-up. Approximately 50% of patients reported symptoms, the most common symptoms at baseline and after 1 year follow-up were diarrhoea, flatulence, fatigue, abdominal discomfort and sore injection lumps. Diarrhoea and fatigue were reported as their main complaint, 23% had > 5 daily episodes of diarrhoea and 59% reported fatigue. However, patients reported a high perceived quality of life, high daily activity, coped with their symptoms and managed their daily life well. Deficiency of vitamin D (27%) and A (13%) were observed. Conclusions Patients with metastatic small-intestinal NET on SSA treatment reported a high frequency of symptoms. Minor improvements were seen after 1-year of follow-up, illustrating that many symptoms might be difficult to improve, or may not be recognised by the health service. Patients, however, generally reported a high quality of life. Care for NET patients on SSA treatment should include a regular systematic symptom registration and vitamin measurements.
