TL;DR: This study demonstrates that normal knee kinematics is achieved in the ACL deficient arthritic knee following ACLR and UKA, and as a result these patients, who tend to be young and high demand, have excellent outcome and achieve high levels of function.
Abstract: The in vivo kinematics of 10 patients after combined anterior cruciate ligament reconstruction (ACLR group) and Oxford unicompartmental knee arthroplasty (UKA) was compared to those of 10 Oxford UKA patients with an intact ACL (ACLI group) and a group of 22 normal knees. The kinematics during a step-up exercise and a deep knee bend exercise was measured using a fluoroscopic technique. The patellar tendon angle (PTA) to knee flexion angle relationship during both exercises was similar for all three groups of subjects. For the UKA groups the pattern of mobile bearing movement during both exercises was similar. This study demonstrates that normal knee kinematics is achieved in the ACL deficient arthritic knee following ACLR and UKA. As a result these patients, who tend to be young and high demand, have excellent outcome and achieve high levels of function. As the relative position of the components and thus component loading are similar to the ACLI UKA, we would expect similar long term survival.

TL;DR: Of the 18 patients tested there were no consistent, generalizable, recognizable patterns of sensory recovery demonstrated, and somatosensory recovery showed marked variation in subtests both within and between patients.
Abstract: Purpose. The aim of this study was to characterize the recovery pattern of stroke patients in the first 6 months following stroke.
Method. Using the Rivermead Assessment of Somatosensory Performance (RASP), the Motricity index and the Barthel Activities of Daily Living (ADL) index, a case series of serial somatosensory and motor measurements was made on 18 patients with a diagnosis of a first ever stroke. Patients comprised 2 distinct groups, acute and subacute. The acute group were seen weekly for the first month post onset and the subacute group were seen monthly for 6 months. Participants were seen at hospital, regional rehabilitation unit and/or the participant's home. Standard local rehabilitation was given.
Results. The somatosensory subtest of proprioception demonstrated the greatest level of recovery. No patient achieved full recovery on all somatosensory subtests. Motor and functional recovery demonstrated continual improvement over time, somatosensory recovery showed marked variation in subtests both within and between patients.
Conclusion. Of the 18 patients tested there were no consistent, generalizable, recognizable patterns of sensory recovery demonstrated.

TL;DR: A Bayesian meta-analysis approach to data from 19 studies on 17 replicated associations with type 2 diabetes yielded point estimates for the genetic effects that were very similar to those previously reported based on fixed- or random-effects models, but uncertainty about several of the effects was substantially larger.
Abstract: For most associations of common single nucleotide polymorphisms (SNPs) with common diseases, the genetic model of inheritance is unknown. The authors extended and applied a Bayesian meta-analysis approach to data from 19 studies on 17 replicated associations with type 2 diabetes. For 13 SNPs, the data fitted very well to an additive model of inheritance for the diabetes risk allele; for 4 SNPs, the data were consistent with either an additive model or a dominant model; and for 2 SNPs, the data were consistent with an additive or recessive model. Results were robust to the use of different priors and after exclusion of data for which index SNPs had been examined indirectly through proxy markers. The Bayesian meta-analysis model yielded point estimates for the genetic effects that were very similar to those previously reported based on fixed- or random-effects models, but uncertainty about several of the effects was substantially larger. The authors also examined the extent of between-study heterogeneity in the genetic model and found generally small between-study deviation values for the genetic model parameter. Heterosis could not be excluded for 4 SNPs. Information on the genetic model of robustly replicated association signals derived from genome-wide association studies may be useful for predictive modeling and for designing biologic and functional experiments.

TL;DR: This series emphasizes the usually incorrect initial diagnosis, the misinterpretation of the histology, the unpredictable prognosis and the failure of current treatment in patients with fibrodysplasia (myositis) ossificans progressiva.
Abstract: Patients with fibrodysplasia (myositis) ossificans progressiva (FOP) (n = 28) were studied for up to 24 years. All had characteristic short big toes potentially recognizable at birth; there were radiographic changes in the toes, thumbs, cervical spine and metaphyses of the long bones, including exostoses. Ossification in the large skeletal muscles began from birth to 16 years (mean age 4.6 years) initially in 25 patients in the neck and upper spinal muscles, and later around the hips, major joints and jaw. The rate and extent of disability was unrelated to the time of onset. There was no evidence that any form of treatment produced consistent benefit. Despite the unique combination of skeletal abnormalities and ectopic ossification, the first diagnosis in patients with FOP was often wrong and usually delayed after ectopic ossification began (mean 2.7 years, range 0-14). Except where presentation was unusual, such as progressive stiffness, this delay was mainly due to failure to recognize the significance of the abnormal toes. The most frequent erroneous histological diagnoses were soft tissue sarcoma or fibromatosis. This series emphasizes the usually incorrect initial diagnosis, the misinterpretation of the histology, the unpredictable prognosis and the failure of current treatment. Despite its extreme rarity, there is a need for wider knowledge of this condition both to avoid clinical errors and to stimulate research.
