BACKGROUND: The majority of Parkinson's disease patients with deep brain stimulation (DBS) use a monopolar configuration, which presents challenges for EEG and MRI studies. The literature reports algorithms to convert monopolar to bipolar settings. PURPOSE/HYPOTHESIS: To assess brain responses of Parkinson's disease patients implanted with DBS during fMRI studies using their clinical and presumed equivalent settings using a published conversion recipe. STUDY TYPE: Prospective...

BACKGROUND: Contrast-enhanced magnetic resonance imaging (CE-MRI) of the breast is highly sensitive for breast cancer detection. Multichannel coils and 3T scanners can increase signal, spatial, and temporal resolution. In addition, the T1 -reduction effect of a gadolinium-based contrast agent (GBCA) is higher at 3T. Thus, it might be possible to reduce the dose of GBCA at 3T without losing diagnostic information. PURPOSE: To compare a three-quarter (0.075 mmol/kg) dose of the high-relaxivity GBCA gadobenate dimeglumine, with a 1...

AIM: To explore how patients in areas without local percutaneous coronary intervention facilities experience patient participation in different phases of the myocardial infarction pathway. BACKGROUND: Acute treatment of myocardial infarction often involves percutaneous coronary intervention. In Norway, this treatment is centralized at certain hospitals; thus, patients often require long-distance transportation and experience frequent hospital transfers. Short hospital stays, transfers between hospitals and the patient's emotional state pose challenges to promoting patient participation...

BACKGROUND: Osteoporosis (OP) results in weak bone and can ultimately lead to fracture. Drugs such as glucocorticoids can also induce OP (glucocorticoid-induced osteoporosis [GIO]). Bone marrow adipose tissue composition and quantity may play a role in OP pathophysiology, but has not been thoroughly studied in GIO compared to primary OP. PURPOSE/HYPOTHESIS: Chemical shift-encoded (CSE) MRI allows detection of subregional differences in bone marrow adipose tissue composition and quantity in the proximal femur of GIO compared to OP subjects and has high agreement with the reference standard of magnetic resonance spectroscopy (MRS)...

BACKGROUND: Variable flip angle (VFA) imaging is widely used for the estimation of T1 relaxation in the prostate, but may have limited repeatability and reproducibility due to its sensitivity to B1 + inhomogeneity. PURPOSE: To assess the repeatability and reproducibility of prostate T1 estimation with and without compensating for B1 + variation. STUDY TYPE: Prospective. POPULATION: Twenty-one volunteers were prospectively recruited and scanned twice on two 3 T MRI scanners, resulting in 84 VFA T1 exams...

Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming and changes in human land use, such as grazing pressure and afforestation, have been suggested to be major threats for biodiversity in the mountain areas, affecting species abundance and causing distribution shifts towards mountaintops. Population shifts towards poles and mountaintops have been documented in several areas, indicating that climate change is one of the key drivers of species' distribution changes...

Bacteria isolated from lesions as well as apparently normal tissues of psittacine birds have previously been reported as taxon 37 and taxon 44 of Bisgaard. 16S rRNA gene sequence comparisons revealed a distant relationship to members of Pasteurellaceae at the species, genus and family levels. The polar lipid profile consisted of the major components phosphatidylethanolamine and phosphatidylglycerol. A new family Psittacicellaceae fam. nov. is proposed with the type genus Psittacicella gen. nov. The new genus Psittacicella includes the type species Psittacicella melopsittaci sp...

INTRODUCTION: In an epidemic context, the identification of suspected cases, among alert or contact cases, leads to caring for persons for whom only a minority will be confirmed cases, with a laboratory diagnosis positive for Ebola. How are suspected cases treated that are not subsequently confirmed and how do they feel about this experience? What are the medical or social consequences? METHODS: A qualitative study was conducted in two countries with a high Ebola risk epidemic situation in 2015-2016 (Senegal, Côte d'Ivoire)...

BACKGROUND: Magnetic resonance relaxometry studies in multiple sclerosis (MS) have suggested that iron accumulates within deep gray matter (DGM) structures early in the disease course. However, the commonly utilized mean R2* and magnetic susceptibility measures reflect regional iron concentration but not a structure's total iron content. Thus, tissue atrophy could impact mean R2* and magnetic susceptibility estimates. PURPOSE: To demonstrate that both average iron concentration and total iron content need to be reported in order to distinguish between atrophy-related and definite magnetic susceptibility changes...

INTRODUCTION: Biliary atresia (BA) represents the leading indication for liver transplantation in childhood. Only few studies reported the outcome of patients who survived more than 20 years on their native liver, and up to date there are no Italian data available. We reported our 40-year single centre experience with long-term follow-up of BA patients. MATERIALS AND METHODS: All consecutive patients who underwent Kasai portoenterostomy (KPE) for BA managed at our Institution between 1975 and 1996 were retrospectively reviewed...

Recent evidence suggests the existence of shared neural resources for rhythm processing in language and music. Such overlaps could be the basis of the facilitating effect of regular musical rhythm on spoken word processing previously reported for typical children and adults, as well as adults with Parkinson's disease and children with developmental language disorders. The present study builds upon these previous findings by examining whether non-linguistic rhythmic priming also influences visual word processing, and the extent to which such cross-modal priming effect of rhythm is related to individual differences in musical aptitude and reading skills...

Vitamin B supplementation can have side effects for human health, including cancer risk. We aimed to elucidate the role of vitamin B12 in lung cancer aetiology via direct measurements of pre-diagnostic circulating vitamin B12 concentrations in a nested case-control study, complemented with a Mendelian randomization (MR) approach in an independent case-control sample. We used pre-diagnostic biomarker data from 5,183 case-control pairs nested within 20 prospective cohorts, and genetic data from 29,266 cases and 56,450 controls...

Aims: The majority of previous research on the association between cardiorespiratory fitness (CRF) and cardiovascular disease (CVD) is based on indirect assessment of CRF in clinically referred predominantly male populations. Therefore, our aim was to examine the associations between VO2peak measured by the gold-standard method of cardiopulmonary exercise testing and fatal and non-fatal coronary heart disease (CHD) in a healthy and fit population. Methods and results: Data on VO2peak from 4527 adults (51% women) with no previous history of cardiovascular or lung disease, cancer, and hypertension or use of antihypertensive medications participating in a large population-based health-study (The HUNT3 Study), were linked to hospital registries and the cause of death registry...

Obesity is a major public health burden associated with neuropsychiatric comorbidities leading to social and occupational impairment. Given the growing prevalence of both obesity and mental disorders worldwide, understanding the risk factors of obesity-related neuropsychiatric comorbidities is crucial to develop preventive strategies and individualized treatments. Recent findings suggest that adiposity-driven inflammation contributes to neuropsychiatric comorbidities in obesity. However, not all obese subjects afflicted with chronic inflammation develop neuropsychiatric symptoms, suggesting additional risk factors...
