P2‐289: PREVALENCE AND CORRELATES OF SUBJECTIVE MEMORY IMPAIRMENT IN A RURAL ITALIAN POPULATION OF SUBJECTS AGED 50 YEARS AND OVER: DATA FROM THE ZAB…

2014

Background: Neuropathology related to dementia slowly accumulates over decades. Consequently, identifying persons at a higher risk of dementia could postpone or prevent dementia by timely targeting modifiable risk factors. In this light, mild cognitive impairment (MCI) has been identified as the transitional stage between normal aging and dementia. So far, the understanding of MCI in thegeneral population remains limited. Therefore,we investigated determinants, MRI-correlates, and prognosis of MCI within the populationbasedRotterdamStudy.Methods:A total of 4198 participants were included in this study. Firstly, we studied age, APOE4 carriership, waist circumference, hypertension, diabetes m…

Background: One of the global targets for non-communicable diseases is to halt, by 2025, the rise in the age standardised adult prevalence of diabetes at its 2010 levels. We aimed to estimate worldwide trends in diabetes, how likely it is for countries to achieve the global target, and how changes in prevalence, together with population growth and ageing, are aff ecting the number of adults with diabetes. Methods: We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes prevalence-defined as fasting plasma glucose of 7.0 mmol/L or higher, or history of diagnosi…

Influence of metal–support interaction on the surface structure of gold nanoclusters deposited on native SiOx/Si substrates

2014

The structure of small gold nanoclusters (R ~ 2.5 nm) deposited on different silica on silicon substrates is investigated using several characterization techniques (AFM, XRD, EXAFS and GISAXS). The grain morphology and the surface roughness of the deposited gold clusters are determined by AFM. The in-plane GISAXS intensity is modelled in order to obtain information about the cluster size and the characteristic length scale of the surface roughness. AFM and GISAXS results are in excellent agreement and show that the surface morphology of the deposited clusters depends on whether defect-rich (native) or defect-free (thermal) silica is used as a substrate. Gold clusters show a strong tendency …

Hepatocellular carcinoma recurrence after acute liver allograft rejection treatment: A multicenter European experience

2019

During the last decades, several risk factors for the recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) have been investigated. However, the impact of two important drivers of oncogenesis, namely the immunosuppression and the treatment of acute cellular rejection (ACR) have been marginally addressed. This study aimed at investigating the impact of ACR treatment on the incidence of tumor recurrence in a large European HCC-LT population. Seven hundred and eighty-one adult patients transplanted between February 1, 1985 and June 30, 2016 were retrospectively analyzed. After propensity score match, 116 patients treated for ACR using steroid boluses were compared with …

Renal Function at Two Years in Liver Transplant Patients Receiving Everolimus: Results of a Randomized, Multicenter Study

2013

In a 24-month prospective, randomized, multicenter, open-label study, de novo liver transplant patients were randomized at 30 days to everolimus (EVR) + Reduced tacrolimus (TAC; n = 245), TAC Control (n = 243) or TAC Elimination (n = 231). Randomization to TAC Elimination was stopped prematurely due to a significantly higher rate of treated biopsy-proven acute rejection (tBPAR). The incidence of the primary efficacy endpoint, composite efficacy failure rate of tBPAR, graft loss or death postrandomization was similar with EVR + Reduced TAC (10.3%) or TAC Control (12.5%) at month 24 (difference -2.2%, 97.5% confidence interval [CI] -8.8%, 4.4%). BPAR was less frequent in the EVR + Reduced TAC…

A higher incidence of moult–breeding overlap in great tits across time is linked to an increased frequency of second clutches: a possible effect of g…

2021

The rise of temperatures due to global warming is related to a lengthening of the breeding season in many bird species. This allows more pairs to attempt two clutches within the breeding season, thus finishing their breeding activity later in the season and therefore potentially overlapping these with post–breeding moult. We tested whether this occurred in two Spanish great tit Parus major populations. The proportion of pairs laying second clutches increased from 1 % to 32 % over the study period in one of the populations (Sagunto, 1995–2019), while it did not change in the other (Quintos, 2006–2019; mean 5 %). We did not find any temporal trend for moult start date of late–breeding birds i…

Female Vascular Senescence

2012

Long before the existence of cardiovascular imaging, Sir William Osler axiom that “man is as old as his arteries”. Followed by several physicians for decades, this aphorism has been widely confirmed by studies demonstrating that risk factors for cardiovascular disease increase as we age (Cooper et al., 1994; Lakatta & Levy, 2003). Nevertheless, a flaw in this statement is the generalization that men and women age similarly. Much data from clinical and basic research have established that vascular aging in women does not follow the same chronology as in men (Shaw et al., 2006; Pereira et al., 2010; Takenouchi et al., 2009). If known risk factors that influence cardiovascular aging are exclud…

Doubling Recruitment of Pediatric Low-grade Glioma within Two Decades does not change Outcome – Report from the German LGG Studies

2021

Successive multicenter studies for pediatric low-grade glioma (LGG) in Germany were accompanied by a doubling of annual recruitment over 2 decades. We investigated whether this increase conveyed a change of epidemiologic characteristics or survival.Participating centers reported 4634 patients with the radiologic/histologic diagnosis of LGG (1996-2018), rising from 109 to 278/year. Relating these numbers to all pediatric CNS tumors registered at the German Childhood Cancer Registry, the LGG fraction and annual crude incidence rates increased (32% to 51%; 0.94 to 2.12/100,000 children/adolescents15 years). The consecutive LGG studies recruited 899 (HIT-LGG 1996), 1592 (SIOP-LGG 2004), and 183…

Frequency of Twin Pregnancies Following Renal Transplantation

1994

Objective: To evaluate the incidence of twin pregnancy among renal-transplanted women.Methods: A retrospective review based on three national inquiries. A computer literature search of the Medline system was done. Only reports of series were included. For statistical analysis the probability of having a twin pregnancy was assumed to be 0.012.Main Outcome Measures: Incidence of twin pregnancy in women after renal transplantation.Results: There were 7 sets of twins among 153 pregnancies reported in the national inquiry group (4.57%). Thus, the overall incidence of twin pregnancy in these women was 1 in 22 pregnancies. The frequency of twinning in series reporting pregnancies after renal trans…

Hypothyroidism and pregnancy. Situation in Latvia

2015

The thyroid gland is the first of the body's endocrine glands to develop, on approximately the 24 th day or 3-4 weeks of gestation, but at around 10-12 weeks the thyroid begins to function on its own. Thyroid hormones are involved in regulation of vital body function. In general normal development, growth and reproduction cannot occur without them. The normal function of thyroid gland is predictor to normal pregnancy outcome and foetus development. It is important to know how many women have hypothyroidism and what kind of treatment they receive. Author selected and made retrospective analysis of women with hypothyroidism maternity cases from 2010 to 2011 year. Data compared to the control …
