Recovery of cortical volume and thickness after remission from acute anorexia nervosa
2018
Objective Reduced grey (GM) and white matter (WM) volumes and increased cerebrospinal fluid (CSF) have been frequently reported in anorexia nervosa (AN), but studies focusing on cortical thickness (CT) are scarce and findings inconsistent. We conducted the first study in AN that analyzed both parameters in the same study to gain novel and comprehensive insight. Method Voxel-based morphometry (VBM) analysis was performed on T1-weighted magnetic resonance images from 34 predominantly adult women with acute AN, 24 REC participants, and 41 healthy controls (HC). Global brain segment volumes (GM, WM, and CSF), regional GM volume, and cortical thickness measures were obtained from the same study …
A new PCSK9 gene promoter variant affects gene expression and causes autosomal dominant hypercholesterolemia.
2008
Autosomal dominant hypercholesterolemia (ADH) is a genetic disorder characterized by increased low-density lipoprotein (LDL)-cholesterol levels, leading to high risk of premature cardiovascular disease. More than 900 mutations in LDL receptor, six in APOB and 10 in PCSK9 have been identified as a cause of the disease in different populations. All known mutations in PCSK9 causing hypercholesterolemia produce an increase in the enzymatic activity of this protease. Up to now, there are data about the implication of PCSK9 in ADH in a low number of populations, not including a Spanish population.The objective of the study was to study the prevalence of PCSK9 mutations in ADH Spanish population.W…
Femtosecond laser versus mechanical microkeratome laser in situ keratomileusis for myopia: Metaanalysis of randomized controlled trials.
2011
Purpose To examine differences in efficacy, accuracy, safety, and changes in aberrations between femtosecond and mechanical microkeratome laser in situ keratomileusis (LASIK) for myopia. Setting Department of Ophthalmology, Shanghai First People's Hospital Affiliated to Shanghai Jiaotong University, Shanghai, China. Design Evidence-based manuscript. Methods Data sources, including PubMed, Medline, EMBASE, and Cochrane Controlled Trials Register, were searched to identify potentially relevant prospective randomized controlled trials. Primary outcome measures were efficacy (uncorrected distance visual acuity ≥20/20), accuracy (±0.50 diopter mean spherical equivalent), and safety (loss of ≥2 l…
Temporal trends and determinants of peripartum hysterectomy in Lombardy, Northern Italy, 1996-2010.
2013
Purpose: To analyze the temporal trends of peripartum hysterectomy (PH) in the period 1996-2010 in Lombardy, Italy. Methods: Using data from the Regional Database, PH ratios/1,000 deliveries were calculated from 1996 to 2010, in strata of age and mode of delivery among women resident in Lombardy, Italy. PH cases were identified searching the database for the ICD-9 and ICD-10 codes for subtotal and total hysterectomy. PH ratios/1,000 deliveries in strata of age, mode of delivery and calendar year were computed. Poisson's regression analysis was used to test trend over time. Results: A total of 905 PH and 1,289,163 deliveries were recorded between 1996 and 2010. The overall PH ratio was 0.70/…
The effect of exposure to radiofrequency fields on cancer risk in the general and working population: A protocol for a systematic review of human obs…
2021
Highlights • RF-EMF was classified by IARC as possibly carcinogenic to humans (2B) in May 2011 • A systematic review of all subject-relevant epidemiological studies is now needed. • A detailed protocol ensures the review's transparency, utility and credibility. • Original study validity will be evaluated with a customized OHAT risk of bias tool. • Internal coherence and external plausibility will inform conclusions.
Second European evidence-based consensus on the prevention, diagnosis and management of opportunistic infections in inflammatory bowel disease
2014
The treatment of inflammatory bowel disease (IBD) has been revolutionised over the past decade by the increasing use of immunomodulators, mainly azathioprine (AZA)/6-mercaptopurine (6-MP) and methotrexate (MTX), together with the advent of biological therapy. Immunomodulators are being used more often and earlier in the course of the disease.1 The introduction of biologic agents, especially inhibitors of the key proinflammatory cytokine, tumor necrosis factor alpha (TNF-α) initiated a new therapeutic era, whose use has grown continuously since their introduction in 1998.2 With such immunomodulation, the potential for opportunistic infection is a key safety concern for patients with IBD. Opp…
Multicomponent Physical Exercise Training in Multimorbid and Palliative Oldest Adults
2021
Exercise counteracts aging and pathology symptoms, but there is still scarce research on exercise programs for multimorbid and/or palliative old patients (MPO-Ps). In order to analyze whether the multicomponent physical–cognitive training is beneficial for this population, 17 MPO-Ps (81.59 ± 5.63 years) completed a >
Tyrosine hydroxylase Val-81-Met polymorphism associated with early-onset alcoholism
2005
The present study examined the association of the Tyrosine hydroxylase Val-81-Met polymorphism with alcohol dependence. One hundred and fifty-nine patients in a psychiatric unit with alcohol dependence were genotyped as well as 92 healthy volunteers. The Val allele was more frequent in patients with alcohol dependence (69.5%) than in controls (62.5%). This effect was largely due to the association with early-onset alcoholism (77.8%), whereas no difference was noted between late-onset patients and controls. Our results suggest a role for tyrosine hydroxylase in early-onset alcoholism.
Effect of an Endurance and Strength Mixed Circuit Training on Regional Fat Thickness: The Quest for the “Spot Reduction”
2021
Accumulation of adipose tissue in specific body areas is related to many physiological and hormonal variables. Spot reduction (SR) is a training protocol aimed to stimulate lipolysis locally, even though this training protocol has not been extensively studied in recent years. Thus, the present study sought to investigate the effect of a circuit-training SR on subcutaneous adipose tissue in healthy adults. Methods: Fourteen volunteers were randomly assigned to spot reduction (SR) or to a traditional resistance training (RT) protocol. Body composition via bioimpedance analysis (BIA) and subcutaneous adipose tissue via skinfold and ultrasound were measured before and after eight weeks of train…
Epidemiology of distal radius fractures in children and adults during the COVID-19 pandemic - a two-center study
2021
Abstract Background Distal radius fractures (DRFs) constitute 15–21% of all fractures. There are no detailed data on the possible changes in the epidemiology and treatment of DRFs in children and adults during the Covid pandemic. The purpose of our study was a comprehensive assessment of the impact of the COVID-19 pandemic on distal radius fractures (DRF) epidemiology, including both children and adults and various fracture fixation methods in two large trauma centers in Poland. Methods This study compared the medical data on the treatment of distal radius fractures in Poland in two periods: the period of the COVID-19 pandemic (from March 15 to October 15, 2020) and the corresponding period…
