Equine cervical intervertebral disc degeneration is associated with location and MRI features

Morphology of the equine cervical intervertebral disc is different from that in humans and small companion animals and published imaging data are scarcely available. The objectives of this exploratory, methods comparison study were (a) to describe MRI features of macroscopically nondegenerated and degenerated intervertebral discs (b) to test associations between spinal location and macroscopic degeneration or MRI-detected annular protrusion and between MRI-detected annular protrusion and macroscopic degeneration, and (c) to define MRI sequences for characterizing equine cervical intervertebral disc degeneration. Ex vivo MRI of intervertebral discs was performed in 11 horses with clinical signs related to the cervical region prior to macroscopic assessment. Mixed-effect logistic regression modeling included spinal location, MRI-detected annular protrusion, and presence of macroscopic degeneration with "horse" as random effect. Odds ratio and 95% confidence interval were determined. Reduced signal intensity in proton density turbo SE represented intervertebral disc degeneration. Signal voids due to presence of gas and/or hemorrhage were seen in gradient echo sequences. Presence of macroscopic intervertebral disc degeneration was significantly associated with spinal location with odds being higher in the caudal (C5 to T1) versus cranial (C2 to C5) part of the cervical vertebral column. Intervertebral discs with MRI-detected annular protrusion grades 2-4 did have higher odds than with grade 1 to have macroscopic degeneration. It was concluded that MRI findings corresponded well with gross macroscopic data. Magnetic resonance imaging of the equine cervical intervertebral disc seems to be a promising technique, but its potential clinical value for live horses needs to be explored further in a larger and more diverse population of horses

Albuminuria and markers for cardiovascular risk in 12-year-olds from the general Dutch population:a cross-sectional study

In adults, albuminuria represents a risk factor for cardiovascular disease and is associated with hypertension and obesity. Pediatric data from the general population are inconsistent and largely based on randomly collected urine. A possible association between antenatal programming and albuminuria at school age has still to be investigated. The purpose of this study is to assess albuminuria in first morning void urine samples in a population-based pediatric cohort and to investigate cross-sectionally the association with factors related to cardiovascular risk. Moreover, we investigate the possible association of antenatal factors with albuminuria. A first morning void urine sample was collected in the population-based GECKO (Groningen Expert Center for Kids with Obesity) Drenthe cohort at the age of 12 years. We investigated cross-sectionally associations between albuminuria and body mass index (BMI), waist circumference (WC), blood pressure (BP) and antenatal factors. The prevalence of U ACR (urinary albumin-creatinine ratio) ≥ 3 mg/mmol was 3.3% (95%CI 2.3-4.2). In a multivariate linear regression model, U AC was negatively associated with z-BMI (β-0.08, p = 0.013) and positively with z-systolic BP (β 0.09, p = 0.006), model significance p = 0.002. U ACR was negatively associated with z-BMI (β - 0.13, p &lt; 0.001) and positively with z-diastolic BP (β 0.09, p = 0.003), model significance p = 0.001. Albuminuria was not significantly associated with antenatal factors such as gestational age and standardized birth weight. CONCLUSIONS: Albuminuria in first morning void urine in 12-year-olds has a lower prevalence than previously reported by randomly collected samples. A negative association between albuminuria and BMI is confirmed. A positive association with blood pressure, but no association with antenatal factors was found.WHAT IS KNOWN: • While, in adults, albuminuria is a recognized risk factor for cardiovascular disease and is associated with hypertension and obesity, pediatric data are inconsistent and largely based on randomly collected urine. • A possible association between antenatal programming and albuminuria at school age has still to be investigated.WHAT IS NEW: • In this population study on first morning void urine samples from 12-year-olds of the general population, albuminuria is negatively associated with body mass index, and positively associated with blood pressure, while there is no association with antenatal factors. • The prevalence of albuminuria at 12 years is lower than previously reported in studies based on randomly collected urine samples, probably due to elimination of orthostatic proteinuria.</p

Women's adjustment trajectories during IVF and impact on mental health 11–17 years later

STUDY QUESTION Do patients present different adjustment trajectories during and after IVF treatment? SUMMARY ANSWER Most women show resilient trajectories during and after IVF treatment but 37% show temporary or chronic maladjustment during IVF and 10% are maladjusted 11–17 years after treatment. WHAT IS KNOWN ALREADY Research on patient psychosocial adjustment during treatment has contributed to identifying the most distressful stages of IVF treatment and profiling patients at risk for emotional maladjustment at these specific stages. This knowledge is currently driving the deliverance of psychosocial care at fertility clinics by tailoring it to patients' risk profiles and specific treatment stages. However, current care does not take into consideration how individuals adjust across the entire treatment pathway. This can be assessed by profiling individual adjustment trajectories. STUDY DESIGN, SIZE, DURATION A longitudinal cohort study with five assessment moments that combines data from two different studies, the STRESSIVF and OMEGA projects. Participants enrolled in the STRESSIVF study (started IVF in 1998–2000) were assessed before and after the first IVF treatment cycle and 6 months and 2.5 years after the last IVF cycle. A subset participated in the OMEGA project (started IVF in 1995–2000) and reported on their mental health 11–17 years after treatment. PARTICIPANTS/MATERIALS, SETTING, METHODS Three hundred and forty-eight women participated in the STRESSIVF project and 108 of these in the OMEGA. Anxiety was measured with the State and Trait Anxiety Inventory, depression with the Beck Depression Inventory and mental health with the Mental Health Inventory. Latent class growth mixed modelling was carried out to identify distinct anxiety and depression trajectories over the four STRESSIVF study assessment moments. Multinominal logistic regressions were conducted to investigate predictors of trajectory membership, and stepwise linear regressions were performed to investigate if adjustment trajectories predicted mental health 11–17 years after IVF treatment. MAIN RESULTS AND THE ROLE OF CHANCE A total of 67 and 86% of women showed normal levels of anxiety and depression, respectively, throughout treatment (resilient trajectories), 24 and 33% experienced anxiety and depression only during treatment (recovery trajectories), 4.6 and 4.9% experienced anxiety and depression only after treatment (delayed trajectories), and 4.3% showed chronic anxiety (chronic trajectory, not identified for depression). Non-resilient trajectories were associated with unsuccessful treatment, marital dissatisfaction, lack of social support and negative infertility cognitions. One in 10 women had a delayed or chronic trajectory and these trajectories predicted serious mental health impairment 11–17 years after treatment. LIMITATIONS, REASONS FOR CAUTION The study only focuses on women. In the OMEGA project adjustment was assessed using a mental health measure. Although we could investigate how trajectories predicted mental health, it would have been preferable to map anxiety and depression trajectories up to 11–17 years after treatment. Missing analysis showed selective dropout from the study but this was accounted for by using mixed models and imputation procedures. Finally, data on other life stressors were not collected; therefore any contribution from these events cannot be assessed. WIDER IMPLICATIONS OF THE FINDINGS Fertility health-care providers have been called upon considering their responsibility in supporting patients in the aftermath of treatment. Results show it is possible to profile different groups of at-risk women at the start of the treatment and tailor psychosocial support to risk profile to promote health adjustment during treatment and thereafter

Longitudinal relationship between albuminuria in infancy and childhood

Background: Mildly increased albuminuria is common in the general adult population and is a strong predictor for cardiovascular events, even in otherwise healthy individuals. The underlying pathophysiological process could be endothelial dysfunction. Previously, we reported that increased albuminuria can also be found in 2-year-olds from the general population. We hypothesized that some individuals have constitutionally higher levels of albuminuria, possibly as an expression of early or inborn endothelial dysfunction. The aim of this study is to evaluate longitudinal persistence of albuminuria from infancy into school age. Methods: In the population-based GECKO (Groningen Expert Center for Kids with Obesity) cohort, urine was collected from 816 children at the age of 2 years as well as 12 years (random urine and first morning void urine, respectively). We evaluated prevalence and persistence of increased albuminuria (U ACR ≥ 3 mg/mmol) at the two time points. Results: The prevalence of U ACR ≥ 3 mg/mmol at 2 and 12 years of age was 31.9% (95% CI 28.7–35.2) and 3.1% (95% CI 2.0–4.5), respectively. U ACR &lt; 3 mg/mmol at both 2 and 12 years of age was present in 540 children (66.2%). Only 9 children (3.5%) of the 260 children with an U ACR ≥ 3 mg/mmol at 2 years had an U ACR ≥ 3 mg/mmol at 12 years (p &lt; 0.001). Conclusion: Albuminuria in 2-year-olds does largely not persist until the age of 12, indicating that albuminuria at 2 years of age is not a marker for constitutional endothelial dysfunction in this cohort.

Prevalence and distribution of (micro)albuminuria in toddlers

Background. Microalbuminuria is common in the general adult population, with a prevalence of similar to 7%, and is an independent indicator of renal and cardiovascular risks. Whether albuminuria is acquired during life (as a result of hypertension/diabetes) or is congenital and already present at birth is unknown. We studied the prevalence of microalbuminuria in toddlers and compared the distribution of albuminuria with that of the general adult population. In addition, we looked for possible associations between microalbuminuria and antenatal, postnatal and maternal factors.Methods. The urinary albumin concentration (U-AC) was measured in 1352 children and the urinary albumin:creatinine ratio (U-ACR) in 1288 children from the Groningen Expert Center for Kids with Obesity (GECKO) Drenthe cohort (age range 20-40 months). Albuminuria distribution was compared with the albuminuria distribution in 40 854 participants of the general adult cohort of the Prevention of Renal and Vascular End stage Disease (PREVEND) study. Associations between albuminuria (expressed as U-AC and U-ACR) and antenatal, postnatal and maternal factors were tested with linear regression analysis.Results. The median U-AC in the GECKO study was 2.3 mg/L (5th-95th percentiles: 2.1-25.5) and in the PREVEND study it was 6.0 mg/L (2.3-28.6) (P distribution comparison 0.053). The prevalence of U-AC a parts per thousand yen 20 mg/L was 6.9% in the GECKO study and 7.8% in the PREVEND study (P = 0.195). The prevalence of U-ACR a parts per thousand yen 30 mg/g in the GECKO study was 23.4%. U-AC and U-ACR were lower in boys. U-AC was not associated with other determinants, but U-ACR was associated with age and gestational diabetes.Conclusions. The distribution of U-AC and the prevalence of U-AC &gt; 20 mg/L in toddlers and in the young general adult population are comparable. These findings suggest that microalbuminuria is a congenital condition that may predispose to a higher cardiovascular risk later in life.</p

Background: Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament has been described in Friesian horses as well as in other breeds. The objectives of this study were to review the outcome of clinical cases of this disease in Friesian horses and analyse the pathology of the bone-ligament interface. Case records of Friesian horses diagnosed with axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament in the period 2002-2012 were retrospectively evaluated. Post-mortem examination was performed on horses that were euthanized (n = 3) and included macroscopic necropsy (n = 3), high-field (9.4 Tesla) magnetic resonance imaging (n = 1) and histopathology (n = 2). Results: Twelve horses were included, aged 6.8 +/- 2.7 years. The hindlimb was involved in all cases. Lameness was acute in onset and severe, with a mean duration of 1.9 +/- 1.0 months. Three horses were euthanized after diagnosis; 9 horses underwent treatment. Two horses (22%) became sound for light riding purposes, 2 horses (22%) became pasture sound (comfortable at pasture, but not suitable for riding), 5 horses (56%) remained lame. In addition to bone resorption at the proximo-axial margin of the proximal sesamoid bones, magnetic resonance imaging and histopathology showed osteoporosis of the peripheral compact bone and spongious bone of the proximal sesamoid bones and chronic inflammation of the intersesamoidean ligament. Conclusions: Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament in the hindlimb of Friesian horses carries a poor prognosis. Pathological characterization (inflammation, proximo-axial bone resorption and remodelling of the peripheral compact bone and spongious bone of the proximal sesamoid bones) may help in unravelling the aetiology of this disease
