Hip-dysplasia (malformation of the coxofemoral joint) in dogs is a major health problem. Under the British Veterinary Association/Kennel Club's voluntary hip-dysplasia scheme, dog-owners/breeders submit radiographs from animals >1-year-old, to ensure adequate skeletal maturity. An overall hip score quantifies the degree of malformation in the hip joints of these animals, by summing the scores for nine components of the radiographs of both the left and right joints. The hip score data for 29,610 Labrador retrievers (registered with The Kennel Club, UK) were merged with the Kennel Club pedigree database for 472,435 Labrador retrievers. The merged data included the animal's identity, date of birth, sex and hip score and similar records for the dog's relatives, including the hip score if the relative had been tested. In recent years, breeding had been increasingly from tested parents. The mean hip score for male Labradors was significantly higher than that for females. Regression modelling showed a significant, positive dependence of the hip score of the offspring upon the hip scores of its sire, dam and grandparents. Genetic heritability (using data from 13,382 Labrador retrievers comprising 718 litters) was highly significant: 0.34 from the two parents, 0.41 from sire alone and 0.30 from dam alone. Using components data from 2038 offspring Labrador retrievers comprising 1248 litters, three similar estimates of heritability were significant for three major components (Norberg angle, cranial acetabular edge and subluxation); for other components, heritability was significant from the sire but not from the dam. Offspring hip score could be reduced substantially by using only parents with zero hip score.

Tumor and viral antigens elicit a potent immune response by heat shock protein-dependent uptake of antigenic peptide with subsequent presentation by MHC I. Receptors on antigen-presenting cells that specifically bind and internalize a heat shock protein-peptide complex have not yet been identified. Here, we show that cells expressing CD40, a cell surface protein crucial for B cell function and autoimmunity, specifically bind and internalize human Hsp70 with bound peptide. Binding of Hsp70-peptide complex to the exoplasmic domain of CD40 is mediated by the NH(2)-terminal nucleotide-binding domain of Hsp70 in its ADP state. The Hsp70 cochaperone Hip, but not the bacterial Hsp70 homologue DnaK, competes formation of the Hsp70-CD40 complex. Binding of Hsp70-ADP to CD40 is strongly increased in the presence of Hsp70 peptide substrate, and induces signaling via p38. We suggest that CD40 is a cochaperone-like receptor mediating the uptake of exogenous Hsp70-peptide complexes by macrophages and dendritic cells.

The positive effect of postlearning sleep on memory consolidation as well as the relationship between sleep-related memory processes and the hippocampal formation are increasingly clarified topics in neurobiology. However, the possibility of a stable relationship between waking mnemonic performance and sleep-dependent hippocampal electric activity is unexplored. Here we report a correlative analysis between sleep-dependent parahippocampal-hippocampal (pHip-Hip) electric activity recorded by foramen ovale (FO) electrodes and different types of memory performances in epileptic patients. Psychological testing was performed days or weeks before electrophysiological recordings. The relative spectral power of the slow activity (below 1.25 Hz) during deep non-REM (NREM) sleep at the right pHip-Hip region correlated positively with the visual memory performance according to Rey-Osterrieth Complex Figure Test (ROCFT). Along the posterior-anterior direction of the hippocampal formation a linear increasing of correlations was observed. The relative power of the activity below 1.25 Hz at the left pHip-Hip during phasic REM sleep correlated positively with verbal learning performance and mnemonic retention values according to ROCFT. It is concluded that the pHip-Hip structures' capacity of producing high amplitude and synchronized slow (< 1 Hz) oscillation during deep NREM sleep is related to the functional power of these structures. We hypothesize that the asymmetric (side-specific) propagation of ponto-geniculo-occipital (PGO) activity to the pHip-Hip region is related to the memory correlates of phasic REM sleep.

Hip fractures are associated with 10% to 20% excess mortality in the first year and cause functional disability in most survivors. An estimated 17% of white women in the United States will sustain a hip fracture after the age of 50 years. Despite the availability of evidence-based guidelines for hip fracture prevention, routine screening and preventive measures have not been incorporated into standard primary care practice. Many physicians lack adequate knowledge to initiate bone mineral density testing and treatment with preventive medications to decrease the incidence of osteoporosis and fractures. Furthermore, patients are less likely to request information about bone health than about diseases for which systematic screening and prevention protocols have been established. This review describes preventive measures to decrease hip fracture in postmenopausal women, including screening by bone mineral density testing, risk factor assessment, and chemoprevention. Existing guidelines are summarized, and dilemmas regarding their implementation are discussed.

The ubiquitin/proteasome system has been proposed to play an important role in Alzheimer's disease (AD) pathogenesis. However, the critical factor(s) modulating both amyloid-beta peptide (Abeta) neurotoxicity and ubiquitin/proteasome system in AD are not known. We report the isolation of an unusual ubiquitin-conjugating enzyme, E2-25K/Hip-2, as a mediator of Abeta toxicity. The expression of E2-25K/Hip-2 was upregulated in the neurons exposed to Abeta(1-42) in vivo and in culture. Enzymatic activity of E2-25K/Hip-2 was required for both Abeta(1-42) neurotoxicity and inhibition of proteasome activity. E2-25K/Hip-2 functioned upstream of apoptosis signal-regulating kinase 1 (ASK1) and c-Jun N-terminal kinase (JNK) in Abeta(1-42) toxicity. Further, the ubiquitin mutant, UBB+1, a potent inhibitor of the proteasome which is found in Alzheimer's brains, was colocalized and functionally interacted with E2-25K/Hip-2 in mediating neurotoxicity. These results suggest that E2-25K/Hip-2 is a crucial factor in regulating Abeta neurotoxicity and could play a role in the pathogenesis of Alzheimer's disease.

The aim of the present study was to investigate the effects of hip arthroplasty followed by an inpatient rehabilitation. Moreover, the relationships among functional status, quality of life and satisfaction with life or health status were examined. Patients were assessed before hip arthroplasty, at the start and at the end of the inpatient rehabilitation. Functional status was measured by using the WOMAC questionnaire and quality of life with the Medical Outcome Survey Short Form 36 (SF-36). Satisfaction was determined with a specific questionnaire (FLZ). Hip arthroplasty followed by an inpatient rehabilitation resulted in significant and clinically highly important improvements of functional status, quality of life and satisfaction with health and life.

Hip fracture incidence accelerates approximately 10 years following the menopause in women and after age 70 in men. Approximately one million Americans suffer fragility fractures each year at a cost of over 14 billion dollars. The disability, mortality and cost of hip and vertebral fractures are substantial in the rapidly growing aging population so that prevention of osteoporosis is a major public health concern. Bone mineral density (BMD) measurement is used to make the diagnosis of osteoporosis prior to incident fracture, and to predict fracture risk. Recommendations for treatment and prevention of osteoporosis based on bone mineral density score published by the World Health Organization and the National Osteoporosis Foundation are outlined.

Ultrasound investigation of the hip according to Graf is performed, whenever possible, as a routine screening test for hip dysplasia and dislocation in neonates. However, in spite of screening, hip dysplasia and/or dislocation is identified in a number of children after the third month of life only. The present study presents an analysis of reasons and causes. Between August 1999 and July 2001 children aged between six months and five years were documented, in whom the diagnosis of hip dysplasia or dislocation was made, despite normal ultrasound findings at primary investigation and who required non operative or operative treatment by a specialist surgeon working in Switzerland in paediatric orthopaedics. The study included 26 children (17 girls / 9 boys). Hip dysplasia and/or dislocation was diagnosed between the age of 6 days and 41 months. Twelve children had to be excluded from the sample (n = 26), four were infants who had basic neurological disorders or multiple anomalies and there were eight children from abroad whose original documentation could not be obtained. Analysis of the remaining 14 children showed that 43% were misdiagnosed (n = 6) and a treatment error occurred in 36% (n = 5) of cases. One child presented with a teratogenic hip dislocation. In two other infants with normal primary ultrasound findings, hip dysplasia was identified radiographically once the child started to walk. Delayed diagnosis can be the result of technical errors or misinterpretation. The six patients meeting the criteria of misinterpretation can be expressed as a rate of 0.04% of all births. However, even if the disorder is correctly diagnosed, its identification and treatment may be inadequate or fail to produce the desired results. This was the case for five of the children, that is, for a rate of 0.03% of births.

Hip fracture occurs commonly in older individuals and can have a considerable impact on the functional independence and quality of life for older patients living in the community. In a population-based case-control study six months after hip fracture, we investigated the association between functionality and quality of life. The Functional Independence Measure (FIM), the Frenchay Activities of Daily Living Index (FAI), and the Berg Balance Scale (BBS) were used to measure physical function, and quality of life was measured by completing a Short Form-36 (SF-36). With age and gender match, the hip fracture group scores were significantly lower (p < or = 0.05) than the control group in all measurements of physical function (FIM 95.54 vs 103.5; FAI 23.68 vs 30.76; BBS 46.21 vs 54.25). The quality of life was assessed by SF-36, which has eight domains: physical function, physical role, bodily pain, mental health, emotional role, social function, general health and vitality. All eight domains were significantly lower in the hip fracture group compared with the controls (p<0.05). The reduction in function was reflected in a reduction in the quality of life. Thus, clinically reported hip fracture impairs both the functionality and quality of life of these subjects. The adverse impact of hip fracture on quality of life and functionality needs to be recognized by health personnel in the community, so that adequate health resources can be devoted to preventing and treating this debilitating condition.

We investigated the natural course of independent sitting in 28 institutionalized patients with severe cerebral palsy (CP) and evaluated the factors associated with presence or absence of independent sitting during adulthood. Seventeen subjects (61%) who could not sit at the age of 10 years were never able to reach the milestone of independent sitting. Five (45%) of 11 subjects subsequently lost the ability to sit independently during the early stage of adult life. In adulthood, many of the dependent sitters had poor activities of daily living (ADL) scores and required medical care for respiration and eating/swallowing. Hip dislocation was not directly associated with the presence or absence of independent sitting. We conclude that it is important to prevent further deterioration of swallowing and respiratory functions, as well as the development of deformities or contractures from childhood and to maintain previously acquired motor function and ADL in adults with severe CP.
