Systematic review and meta-analysis of measurement properties of the Hip disability and Osteoarthritis Outcome Score - Physical Function Shortform (HOOS-PS) and the Knee Injury and Osteoarthritis Outcome Score - Physical Function Shortform (KOOS-PS)

Objective: The aim of this systematic review and meta-analysis was to evaluate all evidence on measurement properties of the Hip disability and Osteoarthritis Outcome Score - Physical function Shortform (HOOS-PS) and the Knee Injury and Osteoarthritis Outcome Score - Physical function Shortform (KOOS-PS). Design: This study was conducted according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of PROMs. MEDLINE, EMBASE, The Cochrane Library, CINAHL and PsychINFO through February 2019 were searched. Eligible studies evaluated patients with hip or knee complaints and described a measurement property, interpretability, feasibility, or the development of either the HOOS-PS or KOOS-PS. Results: Twenty-three studies were included. For both questionnaires, the content validity was found inconsistent and the quality evidence was moderate for a sufficient reliability and high for an insufficient construct validity. The HOOS-PS had a high quality evidence of sufficient structural validity and internal consistency (pooled Cronbach's alpha 0.80; n = 3761) and low quality evidence of sufficient measurement error and indeterminate responsiveness. Concerning the KOOS-PS, the quality evidence was high for an insufficient responsiveness, moderate for an inconsistent structural validity and internal consistency and low for an inconsistent measurement error. Conclusions: The inconsistent evidence for content validity implies that scores on the HOOS-PS and KOOS-PS may inadequately reflect physical functioning. Furthermore, there is evidence for insufficient construct validity and responsiveness in patients with knee osteoarthritis receiving conservative treatment. Using the HOOS-PS or KOOS-PS as outcome measurement instruments for comparing outcomes, measuring improvements or benchmarking in patients with hip or knee complaints or undergoing arthroplasty should only be done with great caution.

Significant association between circumvallate placenta, placental abruption and acute chorioamnionitis in preterm birth:A 23-year retrospective cohort study

Aim:circumvallate placenta, placental abruption and acute chorioamnionitis separately are associated with unfavourable clinical outcomes. We aimed to determine the prevalence and define whether an association exists between the three abnormalities. Methods: 16,042 placenta pathology reports between 1997 and 2020 from a tertiary care centre in the Netherlands were retrospectively analysed. For the statistical analysis, the chi-square test and bootstrapping were used to evaluate an association. Results: In our cohort the prevalence of circumvallate placenta is 2.2 %, placental abruption cases 4.0 % and acute chorioamnionitis 20.6 %. We observed a statistically significant association between all three placental abnormalities: circumvallate placenta, placental abruption and acute chorioamnionitis. In addition, there was also an association between circumvallate placenta and acute chorioamnionitis. Conclusion: Our results show that combined presence of circumvallate placenta, placental abruption and acute chorioamnionitis are associated in preterm birth (p = 0.001). A remarkable finding is that the combination of all three abnormalities (circumvallate placenta, placental abruption and acute chorioamnionitis) was not observed in term pregnancies &gt;37 weeks.</p

Gripforce reduction in children with an upper neonatal brachial plexus palsy

Objective: To assess gripforce in children with a C5 and C6 neonatal brachial plexus palsy, as it may affect hand use. Applying classic innervation patterns, gripforce should not be affected, as hand function is not innervated by C5 or C6. This study compares gripforce in children with a neonatal brachial plexus palsy with that in a healthy control group, and assesses correlations with hand sensibility, bimanual use and external rotation.Methods: A total of 50 children with neonatal brachial plexus palsy (mean age 9.8 years) and 25 controls (mean age 9.6 years) were investigated. Nerve surgery had been performed in 30 children, and 20 children had been treated conservatively. Gripforce of both hands was assessed using a Jamar dynamometer. Sensibility of the hands was assessed with 2-point discrimination and Semmes-Weinstein monofilaments. External rotation was assessed using the Mallet score. Bimanual use was measured by using 1 of 3 dexterity items of the Movement Assessment Battery for Children-2. The affected side of the neonatal brachial plexus palsy group was compared with the non-dominant hand of the control group using 1-way analysis of variance (ANOVA), x(2) and Mann-Whitney tests.Results: The mean gripforce of the affected non-dominant hand of children with neonatal brachial plexus palsy was reduced compared with healthy controls (95 N and 123 N, respectively, with p = 0.001). The mean gripforce of the non-dominant hand in the control group was 92% of that of the dominant hand, while it was only 76% in the neonatal brachial plexus palsy group (p =0.04). There was no relationship between gripforce reduction and sensibility, bimanual use or shoulder external rotation.Discussion: The gripforce in neonatal brachial plexus palsy infants with a C5 and C6 lesion is lower than that of healthy controls, although classic interpretation of upper limb innervation excludes this finding. The reduction in gripforce in upper neonatal brachial plexus palsy lesions is not widely appreciated as a factor inherently compromising hand use. The reduction in gripforce should be taken into consideration in planning the type of rehabilitation and future activities.Scientific Assessment and Innovation in Neurosurgical Treatment Strategie

Mapping aerial metal deposition in metropolitan areas from tree bark : a case study in Sheffield, England

We investigated the use of metals accumulated on tree bark for mapping their deposition across metropolitan Sheffield by sampling 642 trees of three common species. Mean concentrations of metals were generally an order of magnitude greater than in samples from a remote uncontaminated site. We found trivially small differences among tree species with respect to metal concentrations on bark, and in subsequent statistical analyses did not discriminate between them. We mapped the concentrations of As, Cd and Ni by lognormal universal kriging using parameters estimated by residual maximum likelihood ({\sc reml}). The concentrations of Ni and Cd were greatest close to a large steel works, their probable source, and declined markedly within 500~metres of it and from there more gradually over several kilometres. Arsenic was much more evenly distributed, probably as a result of locally mined coal burned in domestic fires for many years. Tree bark seems to integrate airborne pollution over time, and our findings show that sampling and analysing it are cost-effective means of mapping and identifying sources

The clinical effectiveness of concise cognitive behavioral therapy with or without pharmacotherapy for depressive and anxiety disorders; a pragmatic randomized controlled equivalence trial in clinical practice

Background: Depressive and anxiety disorders contribute to a high disease burden. This paper investigates whether concise formats of cognitive behavioral- and/or pharmacotherapy are equivalent with longer standard care in the treatment of depressive and/or anxiety disorders in secondary mental health care. Methods: A pragmatic randomized controlled equivalence trial was conducted at five Dutch outpatient Mental Healthcare Centers (MHCs) of the Regional Mental Health Provider (RMHP) \u27Rivierduinen\u27. Patients (aged 18-65 years) with a mild to moderate anxiety and/or depressive disorder, were randomly allocated to concise or standard care. Data were collected at baseline, 3, 6 and 12 months by Routine Outcome Monitoring (ROM). Primary outcomes were the Brief Symptom Inventory (BSI) and the Web Screening Questionnaire (WSQ). We used Generalized Estimating Equations (GEE) to assess outcomes. Results: Between March 2010 and December 2012, 182 patients, were enrolled (n = 89 standard care; n = 93 concise care). Both intention-to-treat and per-protocol analyses demonstrated equivalence of concise care and standard care at all time points. Severity of illness reduced, and both treatments improved patient\u27s general health status and subdomains of quality of life. Moreover, in concise care, the beneficial effects started earlier. Discussion: Concise care has the potential to be a feasible and promising alternative to longer standard secondary mental health care in the treatment of outpatients with a mild to moderate depressive and/or anxiety disorder. For future research, we recommend adhering more strictly to the concise treatment protocols to further explore the beneficial effects of the concise treatment

Resident training does not influence the complication risk in total knee and hip arthroplasty

Background and purpose - Gaining experience in the surgery room during residency is an important part of learning the skills needed to perform arthroplasties. However, in practice, patients are often not fully comfortable with trainee involvement in their own surgery. Therefore, we investigated complications, revision rates, mortality, and operative time of orthopedic surgeons and residents as primary surgeon performing total knee arthroplasties (TKAs) or total hip arthroplasties (THAs). Patients and methods - In this multi-center retrospective cohort study, 3,098 TKAs and 4,027 THAs performed between 2007 and 2013 were analyzed. Complications, revisions, mortality, and operative time were compared for patients operated on by the orthopedic surgeon or a resident as primary surgeon. An additional analysis was performed to determine whether the complication risk was affected by the postgraduate year of the resident. Results - Orthopedic complication rates were similar (TKA: orthopedic surgeon: 10%, resident: 11%; THA: 9% and 8%), revision rates (TKA: 3% and 2%, THA: 3% and 2%), or mortality rates (TKA: 0.1% and 0.3%, THA: 0.2% and 0.3%). For both procedures a higher non-orthopedic complication rate was found in the resident group (TKA: 8% and 10%; p = 0.03, THA: 8% and 10%; p = 0.01) and a slightly longer operative time (TKA: mean difference 9.0 minutes (8%); THA: 11.3 minutes (11%)). Interpretation - Complications, revisions, and mortality were similar in TKAs or THAs performed by the resident as primary surgeon compared with surgeries performed by an orthopedic surgeon. This data can be used in teaching hospitals and may help to reassure patients.Orthopaedics, Trauma Surgery and Rehabilitatio

Endoglin is an important mediator in the final common pathway of chronic kidney disease to end-stage renal disease

Chronic kidney disease (CKD) is a slow-developing, progressive deterioration of renal function. The final common pathway in the pathophysiology of CKD involves glomerular sclerosis, tubular atrophy and interstitial fibrosis. Transforming growth factor-beta (TGF-beta) stimulates the differentiation of fibroblasts towards myofibroblasts and the production of extracellular matrix (ECM) molecules, and thereby interstitial fibrosis. It has been shown that endoglin (ENG, CD105), primarily expressed in endothelial cells and fibroblasts, can function as a co-receptor of TGF signaling. In several human organs, endoglin tends to be upregulated when chronic damage and fibrosis is present. We hypothesize that endoglin is upregulated in renal interstitial fibrosis and plays a role in the progression of CKD. We first measured renal endoglin expression in biopsy samples obtained from patients with different types of CKD, i.e., IgA nephropathy, focal segmental glomerulosclerosis (FSGS), diabetic nephropathy (DN) and patients with chronic allograft dysfunction (CAD). We showed that endoglin is upregulated in CAD patients (p Immunopathology of vascular and renal diseases and of organ and celltransplantationIP1
