ABSTRACT

Less is known about the risk of fracture in people with rheumatoid arthritis aged under 50 than those in older age groups. The study shows that the risk of fracture before age 50 remains significantly higher in those with rheumatoid arthritis than matched controls. This has implications for fracture risk management. INTRODUCTION: To determine the risk of first and subsequent fracture occurring before age 50 in people diagnosed with rheumatoid arthritis (RA) before age 50. METHODS: A retrospective observational cohort study of RA cases with matched controls using data from Clinical Practice Research Datalink (CPRD) of adults ≥ 18 years with diagnosis of RA recorded from 1992 to 2016 in the UK. Patients were followed from index date to the first fracture and subsequent fracture. A total of 36,858 cases were each matched to 3 controls. Incidence rates (IR) and incidence rate ratios (IRR) of first and subsequent fractures were calculated. A multivariate Cox's proportional hazards model was used to calculate the risk of first fracture and of subsequent fracture in the presence of different risk factors. RESULTS: The IR of first and subsequent fractures at any age is significantly higher in cases than controls for patients with onset of RA at any age. This includes first fractures occurring before age 50 for those diagnosed with RA before this age. In women, the rate of first fracture before age 50 are significantly higher than matched controls (IRR 1.29 CI 1.12-1.49), the IRR for subsequent fracture is higher but not significantly so. For men, the IRRs of first and subsequent fractures below age 50 are also higher but not significantly so. Gender, previous fracture, glucocorticoid prescription, osteoporosis diagnosis, alcohol, smoking, and bisphosphonate prescription have a significant effect on the risk of first fracture at any age for RA patients; all these variables except osteoporosis diagnosis and alcohol have a significant effect on the risk of subsequent fracture and first fractures before age 50. CONCLUSIONS: These results indicate an increased risk of first fracture before age 50 in people with RA diagnosed before this age. It is important that patients with RA of all ages are given timely support from the time of diagnosis to protect their bone health.

ABSTRACT

UNLABELLED: Men and women with hip fracture have higher short-term mortality. This study investigated mortality risk over two decades post-fracture; excess mortality remained high in women up to 10 years and in men up to 20 years. Cardiovascular disease (CVD) and pneumonia were leading causes of death with a long-term doubling of risk. INTRODUCTION: Hip fractures are associated with increased mortality, particularly short term. In this study with a two-decade follow-up, we examined mortality and cause of death compared to the background population. METHODS: We followed 1013 hip fracture patients and 2026 matched community controls for 22 years. Mortality, excess mortality, and cause of death were analyzed and stratified for age and sex. Hazard ratio (HR) was estimated by Cox regression. A competing risk model was fitted to estimate HR for common causes of death (CVD, cancer, pneumonia) in the short and long term (>1 year). RESULTS: For both sexes and at all ages, mortality was higher in hip fracture patients across the observation period with men losing most life years (p < 0.001). Mortality risk was higher for up to 15 years (women (risk ratio (RR) 1.9 [95 % confidence interval (CI) 1.7-2.1]); men (RR 2.8 [2.2-3.5])) and until end of follow-up ((RR 1.8 [1.6-2.0]); (RR 2.7 [2.1-3.3])). Excess mortality by time intervals, censored for the first year, was evident in women (<80 years, up to 10 years; >80 years, for 5 years) and in men <80 years throughout. CVD and pneumonia were predominant causes of death in men and women with an associated higher risk in all age groups. Pneumonia caused excess mortality in men over the entire observation period. CONCLUSION: In a remaining lifetime perspective, all-cause and excess mortality after hip fracture was higher even over two decades of follow-up. CVD and pneumonia reduce life expectancy for the remaining lifetime and highlights the need to further improve post-fracture management.

ABSTRACT

UNLABELLED: In 27 centres across Europe, the prevalence of deforming spinal Scheuermann's disease in age-stratified population-based samples of over 10,000 men and women aged 50+ averaged 8% in each sex, but was highly variable between centres. Low DXA BMD was un-associated with Scheuermann's, helping the differential diagnosis from osteoporosis. INTRODUCTION: This study aims to assess the prevalence of Scheuermann's disease of the spine across Europe in men and women over 50 years of age, to quantitate its association with bone mineral density (BMD) and to assess its role as a confounder for the radiographic diagnosis of osteoporotic fracture. METHODS: In 27 centres participating in the population-based European Vertebral Osteoporosis Study (EVOS), standardised lateral radiographs of the lumbar and of the thoracic spine from T4 to L4 were assessed in all those of adequate quality. The presence of Scheuermann's disease, a confounder for prevalent fracture in later life, was defined by the presence of at least one Schmorl's node or irregular endplate together with kyphosis (sagittal Cobb angle >40° between T4 and T12) or a wedged-shaped vertebral body. Alternatively, the (rare) Edgren-Vaino sign was taken as diagnostic. The 6-point-per-vertebral-body (13 vertebrae) method was used to assess osteoporotic vertebral shape and fracture caseness. DXA BMD of the L2-L4 and femoral neck regions was measured in subsets. We also assessed the presence of Scheuermann's by alternative published algorithms when these used the radiographic signs we assessed. RESULTS: Vertebral radiographic images from 4486 men and 5655 women passed all quality checks. Prevalence of Scheuermann's varied considerably between centres, and based on random effect modelling, the overall European prevalence using our method was 8% with no significant difference between sexes. The highest prevalences were seen in Germany, Sweden, the UK and France and low prevalences were seen in Hungary, Poland and Slovakia. Centre-level prevalences in men and women were highly correlated. Scheuermann's was not associated with BMD of the spine or hip. CONCLUSIONS: Since most of the variation in population impact of Scheuermann's was unaccounted for by the radiological and anthropometric data, the search for new genetic and environmental determinants of this disease is encouraged.

ABSTRACT

UNLABELLED: In a prospective cohort study of 395 geriatric outpatients, mortality after 3 years was associated with prevalent vertebral fractures at baseline. The mortality risk was independently associated with the presence of three or more vertebral fractures at baseline. In the surviving patients, the risk of incident fractures was noteworthy, occurring in 26 % of these patients. INTRODUCTION: The purpose of this study is to determine mortality rate and the incidence of vertebral fractures in a geriatric outpatient group, during a 3-year follow-up period, in a teaching hospital in Amsterdam, The Netherlands. METHODS: This study includes a prospective cohort study of 395 geriatric patients who had their baseline visit at a diagnostic day hospital in 2007 and 2008. They were invited for follow-up 3 years later. Lateral X-rays of the lumbar spine and chest were performed at baseline and after 3 years; vertebral fractures were scored in all patients according to the semi-quantitative method of Genant. RESULTS: After 3 years, mortality was 46 % and associated with prevalent vertebral fractures at baseline (odds ratio (OR), 1.83; 95 % CI, 1.23-2.74). The presence of three or more vertebral fractures at baseline was an independent risk factor for mortality (OR, 3.32; 95 % CI, 1.56-7.07). Other independently associated risk factors were greater age, higher co-morbidity score, and having more prescriptions. Higher cognitive capacity protected against mortality after 3 years. In 72 patients, radiography was repeated. Nineteen patients (26 %) had an incident radiographic vertebral fracture: 16 in those with a prevalent fracture, and 3 in those without a prevalent vertebral fracture at baseline. CONCLUSIONS: In geriatric outpatients, mortality after 3 years was associated with prevalent vertebral fractures at baseline, and the mortality risk was independently associated with 3 or more vertebral fractures at baseline. In survivors, the risk of incident fractures was noteworthy, since these occurred in 26 % of the patients, particularly in those with a prevalent vertebral fracture.

ABSTRACT

The aim of this study was to assess the prevalence, management and impact on quality of life of chronic musculoskeletal pain in Ireland by comparing the attitudes and perceptions of sufferers to those of general practice doctors (GPs). A telephone survey was conducted with 498 people with chronic musculoskeletal pain (screened from a total of 3323) and 150 GPs selected randomly from the medical register. The survey was based on a structured questionnaire that asked about the impact of CMP, usual management and perceived benefits and risks of treatment. Chronic musculoskeletal pain, including arthritis, affected one in six of the people screened for the survey. 25% of those surveyed have never consulted a doctor about their condition and many others will have waited up to two years before seeking help. 67% of respondents reported that pain caused significant reduction in their quality of life (measured using the SF-12 scale). The survey also indicated that people with chronic musculoskeletal pain have misconceptions about their condition, treatment options and side effects and patients rarely receive written information from their GP on these subjects. Chronic musculoskeletal pain, including arthritis is common and significantly reduces quality of life in Ireland. People delay seeking medical help, despite being in constant/daily pain. Written information is sparse and misperceptions relating to treatment are common. Improved awareness and valid information may lead to better care for people suffering from CMP in Ireland.

ABSTRACT

To address the burden of musculoskeletal (MSK) conditions, a competent health workforce is required to support the implementation of MSK models of care. Funding is required to create employment positions with resources for service delivery and training a fit-for-purpose workforce. Training should be aligned to define "entrustable professional activities", and include collaborative skills appropriate to integrated and people-centred care and supported by shared education resources. Greater emphasis on educating MSK healthcare workers as effective trainers of peers, students and patients is required. For quality, efficiency and sustainability of service delivery, education and research capabilities must be integrated across disciplines and within the workforce, with funding models developed based on measured performance indicators from all three domains. Greater awareness of the societal and economic burden of MSK conditions is required to ensure that solutions are prioritised and integrated within healthcare policies from local to regional to international levels. These healthcare policies require consumer engagement and alignment to social, economic, educational and infrastructure policies to optimise effectiveness and efficiency of implementation.

ABSTRACT

We have previously shown that center- and sex-specific fall rates explained one-third of between-center variation in upper limb fractures across Europe. In this current analysis, our aim was to determine how much of the between-center variation in fractures could be attributed to repeated falling, bone mineral density (BMD), and other risk factors in individuals, and to compare the relative contributions of center-specific BMD vs. center-specific fall rates. A clinical history of fracture was assessed prospectively in 2451 men and 2919 women aged 50-80 from 20 centers participating in the European Prospective Osteoporosis Study (EPOS) using standardized questionnaires (mean follow-up = 3 years). Bone mineral density (BMD, femoral neck, trochanter, and/or spine) was measured in 2103 men and 2565 women at these centers. Cox regression was used to model the risk of incident fracture as a function of the person-specific covariates: age, BMD, personal fracture history (PFH), family hip fracture history (FAMHIP), time spent walking/cycling, number of 'all falls' and falls not causing fracture ('fracture-free') during follow-up, alcohol consumption, and body mass index. Center effects were modeled by inclusion of multiplicative gamma-distributed random effects, termed center-shared frailty (CSF), with mean 1 and finite variance theta (theta) acting on the hazard rate. The relative contributions of center-specific fall risk and center-specific BMD on the incidence of limb fractures were evaluated as components of CSF. In women, the risk of any incident nonspine fracture (n = 190) increased with age, PFH, FAMHIP, > or =1 h/day walking/cycling, and number of 'all falls' during follow-up (all P < 0.074). 'Fracture-free' falls (P = 0.726) and femoral neck BMD did not have a significant effect at the individual level, but there was a significant center-shared frailty effect (theta = 0.271, P = 0.001) that was reduced by 4% after adjusting for mean center BMD and reduced by 19% when adjusted for mean center fall rate. Femoral trochanter BMD was a significant determinant of lower limb fractures (n = 53, P = 0.014) and the center-shared frailty effect was significant for upper limb fractures (theta = 0.271, P = 0.011). This upper limb fracture center effect was unchanged after adjusting for mean center BMD but was reduced by 36% after adjusting for center mean fall rates. In men, risk of any nonspine fracture (n = 75) increased with PFH, fall during follow-up (P < 0.026), and with a decrease in trochanteric BMD [RR 1.38 (1.08, 1.79) per 1 SD decrease]. There was no center effect evident (theta = 0.081, P = 0.096). We conclude that BMD alone cannot be validly used to discriminate between the risk of upper limb fractures across populations without taking account of population-specific variations in fall risk and other factors. These variations might reflect shared environmental or possibly genetic factors that contribute quite substantially to the risk of upper limb fractures in women.

ABSTRACT

Human parvovirus B19 has been associated with various clinical effects in a number of uncontrolled reports. To define the usual manifestations of B19 infection in adults and the factors that influence them we present a clinicoepidemiological study of an outbreak of B19 infection centered on a junior school. Four hundred fifty-three of 475 adults in this community were interviewed and blood was obtained for serological diagnosis. Fifty-four cases of recent infection were identified and were HLA typed. Fourteen of the cases were asymptomatic; 32 had an influenzalike illness; 23 a rash; and 26 an acute-onset polyarthropathy that was more common in women and lasted for up to 7 months. HLA-A, -B, and -C antigen frequencies were similar to a local control population and showed no association with symptoms except that HLA-DR1 was absent in those with persistent arthropathy.

ABSTRACT

UNLABELLED: More severe vertebral fractures have more personal impact. In the European Prospective Osteoporosis Study, more severe vertebral collapse was predictable from prior fracture characteristics. Subjects with bi-concave or crush fractures at baseline had a 2-fold increase in incident fracture size and thus increased risk of a disabling future fracture. INTRODUCTION: According to Euler's buckling theory, loss of horizontal trabeculae in vertebrae increases the risk of fracture and suggests that the extent of vertebral collapse will be increased in proportion. We tested the hypothesis that the characteristics of a baseline deformity would influence the size of a subsequent deformity. METHODS: In 207 subjects participating in the European Prospective Osteoporosis Study who suffered an incident spine fracture in a previously normal vertebra, we estimated loss of volume (fracture size) from plane film images of all vertebral bodies that were classified as having a new fracture. The sum of the three vertebral heights (anterior, mid-body, and posterior) obtained at follow-up was subtracted from the sum of the same measures at baseline. Each of the summed height loss for vertebrae with a McCloskey-Kanis deformity on the second film was expressed as a percentage. RESULTS AND CONCLUSIONS: In univariate models, the numbers of baseline deformities and the clinical category of the most severe baseline deformity were each significantly associated with the size of the most severe incident fracture and with the cumulated sum of all vertebral height losses. In multivariate modeling, age and the clinical category of the baseline deformity (crush > bi-concave > uni-concave > wedge) were the strongest determinants of both more severe and cumulative height loss. Baseline biconcave and crush fractures were associated at follow-up with new fractures that were approximately twice as large as those seen with other types of deformity or who previously had undeformed spines. In conclusion, the characteristics of a baseline vertebral deformity determines statistically the magnitude of vertebral body volume lost when a subsequent fracture occurs. Because severity of fracture and number of fractures are determinants of impact, the results should improve prediction of the future personal impact of osteoporosis once a baseline prevalent deformity has been identified.

ABSTRACT

Vertebral fracture is one of the major adverse clinical consequences of osteoporosis; however, there are few data concerning the incidence of vertebral fracture in population samples of men and women. The aim of this study was to determine the incidence of vertebral fracture in European men and women. A total of 14,011 men and women aged 50 years and over were recruited from population-based registers in 29 European centers and had an interviewer-administered questionnaire and lateral spinal radiographs performed. The response rate for participation in the study was approximately 50%. Repeat spinal radiographs were performed a mean of 3.8 years following the baseline film. All films were evaluated morphometrically. The definition of a morphometric fracture was a vertebra in which there was evidence of a 20% (+4 mm) or more reduction in anterior, middle, or posterior vertebral height between films--plus the additional requirement that a vertebra satisfy criteria for a prevalent deformity (using the McCloskey-Kanis method) in the follow-up film. There were 3174 men, mean age 63.1 years, and 3,614 women, mean age 62.2 years, with paired duplicate spinal radiographs (48% of those originally recruited to the baseline survey). The age standardized incidence of morphometric fracture was 10.7/1,000 person years (pyr) in women and 5.7/1,000 pyr in men. The age-standardized incidence of vertebral fracture as assessed qualitatively by the radiologist was broadly similar-12.1/1,000 pyr and 6.8/1,000 pyr, respectively. The incidence increased markedly with age in both men and women. There was some evidence of geographic variation in fracture occurrence; rates were higher in Sweden than elsewhere in Europe. This is the first large population-based study to ascertain the incidence of vertebral fracture in men and women over 50 years of age across Europe. The data confirm the frequent occurrence of the disorder in men as well as in women and the rise in incidence with age.

ABSTRACT

This study investigated the effectiveness of a poison center-initiated mailed intervention on improving the preventive practices of families whose preschool child had recently experienced a poisoning incident. A low-cost, mailed poisoning prevention packet consisting of telephone stickers, a +f41 coupon for syrup of ipecac, one slide-style cabinet lock, a nine-step checklist for "poison-proofing" the home, pamphlets, and a cover letter was tested prospectively on a population of parents calling a poison center for advice about possible poisoning exposures involving their preschool children. Parents without ipecac 1 week after the incident were randomized so that half received the mailed intervention. A "blind" follow-up telephone interview was conducted 3 months later. Of the 336 original families enrolled in the study, 301 (90% retention) completed the follow-up interview. Those who had received the intervention were more likely to have a telephone sticker than control families (78% vs 39%; P < .0001) and were more likely to be using at least one slide lock in the home (59% vs 40%; P < .001). However, intervention families were no more likely to have ipecac on hand than control families (57% vs 52%; P = not significant) and did not indicate a higher rate of compliance with suggested changes in other behaviors and practices to prevent poisonings. A poisoning recurrence rate of 3.7% was seen in the total sample during the 3-month period of surveillance; there was no difference between groups in recurrence rate. Even after a poisoning event, parents may not be sufficiently motivated to take poisoning prevention measures on their own.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

The first poison centers were established in the United States in the early 1950s, stimulated by an American Academy of Pediatrics' survey of office-based pediatric practices which ascertained that its members had no place to turn for ingredient information on medications and household products. With the help of the Academy, pediatrician Dr. Edward Press, the Illinois Department of Health, and several community hospitals, the first poison center emerged. Over the subsequent 40 years, remarkable progress has occurred in the fields of clinical toxicology, poison control, and poison prevention. Yet despite these accomplishments, challenging clouds are appearing on the horizon which threaten these gains. This commentary, by the authors who have viewed and participated in a large part of the history of this progress, will focus on these major accomplishments with an emphasis on (a) poison prevention utilizing the pre-event (primary prevention), (b) the event (secondary prevention), and (c) the postevent (tertiary prevention) model.

ABSTRACT

Osteoporosis is the reduction of expected bone mass. This results in structural failure with an increased risk of fracture and it is the most common bone disorder encountered. Bone mass declines with age, and in some people will fall below the threshold for easy fracture. This loss is accelerated in the postmenopausal period. Trauma and the internal trabecular structure of bone are additional determinants of risk of fracture. Effective management of osteoporosis depends on identifying and treating those at risk before reaching the critical bone mass and presenting with skeletal failure. There are limitations to methods available for assessing bone loss, and the final arbiter of any treatment is prevention of fracture. Primary prevention involves maximising peak adult bone mass and reducing the rate of bone loss. This may be attained by exercise, adequate dietary calcium, and the identification and treatment of risk factors such as postmenopausal hormone replacement. Once skeletal failure has occurred, long term treatment is required to have a clinically significant effect. Increasing bone mass cannot be assumed to reduce the risk of fracture, and such a reduction has not been directly demonstrated for several agents. Calcium supplements, hormone replacement therapy and fluoride are probably effective in reducing fracture rate, particularly when used in combination, whereas the efficacy of anabolic steroids, calcitonin and diphosphonates is yet to be established. Vitamin D is only of use in coexistent osteomalacia. The limitation of significantly strengthening the skeleton during the life expectancy of the elderly must be realised.

ABSTRACT

Parvoviruses (PVs) are unique in that they are the only single-stranded DNA viruses of vertebrates. Two human PVs have now been described and characterized, and genomes sequenced: B19 and RA-1. The B19 PV is known to be associated with arthritis in humans, and RA-1 was recovered from the synovial cells of a patient with rheumatoid arthritis. This article will discuss the nature of these two viruses, their possible relationships to chronic joint disease of humans, and the clinical illnesses of B19 infection.

ABSTRACT

BACKGROUND: While many previous reports describe injuries to adolescents in the workplace, few focus on toxic substance exposures among such injuries. Yet low-skill, entry-level jobs pose a particular hazard of toxic exposure owing to the frequent use of cleaning agents, solvents, and/or other chemicals in carrying out assigned tasks. OBJECTIVE: To analyze the types and severity of adolescent occupational toxic exposures. DESIGN: Secondary analysis of calls to a single regional poison control center (PCC). SETTING: Massachusetts PCC poisoning consultations between 1991 and 1996. SUBJECTS: Children aged 19 years or younger reporting toxic exposures occurring in the workplace. RESULTS: Of 7024 occupational toxic exposures recorded by the PCC in the 6 years of study, 269 incidents (3.8%) involved adolescents aged 14 to 19 years (median age, 18 years; 124 aged 14-17 years and 145 aged 18-19 years; 65% were male). The most frequently involved agents were cleaning compounds (27.8%); paints, solvents, and glues (9.0%); caustics (8.7%); hydrocarbons (8.7%); and bleaches (7.3%). Of 88 cases (32.7%) in which a worksite was identified, food services (30.7%), automotive services (14.8%), and general retail stores (12.5%) were the most common locations. One hundred fifty-six patients (58.0%) were triaged to an emergency department; 7 were hospitalized. Forty-three subjects (16.0%), 18 who were between the ages of 14 and 17 years and 25 who were aged 18 or 19 years, were judged to have moderate to severe injuries. There were no deaths. CONCLUSIONS: This study confirmed the usefulness of PCC surveillance as a source of information about adolescent toxic exposures occurring in the workplace. The occupational toxic exposures reported here most commonly involved cleaning agents, solvents, paints, caustics, and bleach used in those entry-level jobs most frequently filled by adolescents. We conclude that occupational toxic exposures are an underrecognized adolescent injury, and that PCC experience can be used to fill a gap in the surveillance of such workplace-associated events.

ABSTRACT

Childhood drug overdoses are a continuing important public health problem. Although drug overdoses are no longer the important cause of childhood mortality they once were, such poisonings account for highly frequent and unacceptable instances of childhood injuries. These poisonings exact a high cost from society. They result in many emergency department visits and hospitalisations, with the attendant indirect costs of suffering, parental anxiety, and lost days of work or school. Childhood drug overdoses are preventable; those children and families at highest risk show identifiable characteristics, and the medications which pose the greatest hazard to children have already been identified. These injuries divert expensive and scarce medical resources from society's other health problems. Thus, clinicians must do more to prevent childhood drug overdoses whenever possible.

ABSTRACT

Phenothiazines have been widely used for their antiemetic, antipsychotic and sedative properties for many years. The introduction of alternative agents for paediatric sedation has led to the re-evaluation of phenothiazines as paediatric sedatives. Newer agents, such as fentanyl and midazolam, have short half-lives and reversal agents are available. Therefore these agents may offer comparable therapeutic efficacy with a better safety profile in young children. Reports of sudden infant death syndrome in children receiving a phenothiazine-containing syrup for symptoms of upper respiratory infection means that the outpatient use of these compounds in very young infants is not recommended.

ABSTRACT

STUDY OBJECTIVE: This analysis aimed to determine the frequency of falls in men and women aged 50 years and over and to explore whether age variation in fall frequency may explain variation in the incidence of distal forearm fracture in women. DESIGN: This was a cross sectional survey. SETTING: Primary care based registers in four UK areas. PARTICIPANTS: Altogether 501 men and 702 women age 50-79 years participated. MAIN RESULTS: A total of 131 (26.1%) men and 181 (25.8%) women reported falling in the previous year. In women, the frequency of falls rose with age (chi 2 test for trend 4.33; p = 0.04), with no obvious early post-menopausal peak or subsequent decline. Men aged 50-54 years had a significantly increased risk of falls compared with women of this same age group, (odds ratio (OR) = 2.4; 95% confidence interval (CI) 1.3, 4.6), though above this age, the risk of falling was greater in women (OR = 1.2; 95% CI 0.9, 1.5). CONCLUSION: There are important differences in the frequency of falls in relation to age and sex. The data suggest that variation in fall frequency per se does not explain age variation in the incidence of distal forearm fracture in women.
