The aims of this study were to examine long-term survival in a population-based sample of spinal cord injury (SCI) survivors in Great Britain, identify risk factors contributing to deaths and explore trends in cause of death over the decades following SCI. Current survival status was successfully identi®ed in 92.3% of the study sample. Standardised mortality ratios (SMRs) were calculated and compared with a similar USA study. Relative risk ratio analysis showed that higher mortality risk was associated with higher neurologic level and completeness of spinal cord injury, older age at injury and earlier year of injury. For the entire ®fty year time period, the leading cause of death was related to the respiratory system; urinary deaths ranked second followed by heart disease related deaths, but patterns in causes of death changed over time. In the early decades of injury, urinary deaths ranked ®rst, heart disease deaths second and respiratory deaths third. In the last two decades of injury, respiratory deaths ranked ®rst, heart related deaths were second, injury related deaths ranked third and urinary deaths fourth. This study also raises the question of examining alternative neurological groupings for future mortality risk analysis.
We were surprised to find that vascular patients in a contemporary setting who require major lower extremity amputation and rehabilitation often remain independent despite infrequent prosthesis use and outdoor ambulation. Although any hope for postoperative ambulation in this population requires salvaging the knee joint, because of the morbidity incurred in both wound healing and rehabilitation efforts, aggressive effort should be reserved for selected patients at good risk. Ability to predict ambulation after BKA in the vascular population is poor.
This study tested the hypothesis that patients with PAD have impaired health-related quality of life (HRQoL) to a degree similar to that of patients with other types of cardiovascular disease (other-CVD), and also evaluated the clinical features of PAD associated with impaired HRQoL. This was a cross-sectional study in 350 primary care practice sites nationwide with 6,499 participants. The reference group had no clinical or hemodynamic evidence of PAD or other-CVD; the PAD group had an ankle-brachial index < 0.90 or a prior history of PAD; the other-CVD group had a clinical history of cardiac or cerebral vascular disease (but no PAD), and the combined PAD-other-CVD group included both diagnoses. Individuals were assessed using four HRQoL questionnaires including the Walking Impairment Questionnaire (WIQ), Medical Outcomes Study SF-36 (SF-36), Cantril Ladder of Life and the PAD Quality of Life questionnaire. PAD patients had lower WIQ distance scores than the other-CVD group. Both the PAD and other-CVD groups had significantly lower SF-36 Physical Function scores compared with the reference group. The WIQ revealed that PAD patients were more limited by calf pain, whereas other-CVD patients were more limited by chest pain, shortness of breath and palpitations. In conclusion, in this nationwide study, one of the first to directly compare the HRQoL burden of CVD with that of PAD, the evaluation of PAD in office practice revealed a HRQoL burden as great in magnitude as in patients with other forms of CVD.
Background—
Peripheral arterial disease (PAD) and diabetes are both associated with a high risk of ischemic events, but the role of intensive blood pressure control in PAD has not been established.
Methods and Results—
The Appropriate Blood Pressure Control in Diabetes study followed 950 subjects with type 2 diabetes for 5 years; 480 of the subjects were normotensive (baseline diastolic blood pressure of 80 to 89 mm Hg). Patients randomized to placebo (moderate blood pressure control) had a mean blood pressure of 137±0.7/81±0.3 mm Hg over the last 4 years of treatment. In contrast, patients randomized to intensive treatment with enalapril or nisoldipine had a mean 4-year blood pressure of 128±0.8/75±0.3 mm Hg (
P
<0.0001 compared with moderate control). PAD, which is defined as an ankle-brachial index <0.90 at the baseline visit, was diagnosed in 53 patients. In patients with PAD, there were 3 cardiovascular events (13.6%) on intensive treatment compared with 12 events (38.7%) on moderate treatment (
P
=0.046). After adjustment for multiple cardiovascular risk factors, an inverse relationship between ankle-brachial index and cardiovascular events was observed with moderate treatment (
P
=0.009), but not with intensive treatment (
P
=0.91). Thus, with intensive blood pressure control, the risk of an event was not increased, even at the lowest ankle-brachial index values, and was the same as in a patient without PAD.
Conclusions—
In PAD patients with diabetes, intensive blood pressure lowering to a mean of 128/75 mm Hg resulted in a marked reduction in cardiovascular events.
The aim of the present study was to document bone mineral density (BMD) in children with myelomeningocele and to identify variables that contribute to reduced BMD. The study included 24 children with myelomeningocele (nine males, 15 females; age range 4–18y), who had varied levels of neurological impairment (thoracic/high‐lumbar, n=6; mid‐lumbar, n=9; sacral, n=9) and ambulatory status (non‐ambulators, n=12; part‐time ambulators n=2; full‐time ambulators, n=10). BMD measurements of the femoral neck and whole body using dual energy X‐ray absorptiometry assessments of dietary calcium intake, and serum markers of bone metabolism were obtained. BMD is presented as standardized scores (z‐scores) which are age‐ and sex‐matched to normally developing children. The mean femoral‐neck z‐score was −2.41. Femoral‐neck z‐scores differed significantly according to ambulatory status, with lower z‐scores in children who were wheelchair‐dependent (p=0.03). The mean z‐score at the femoral neck demonstrated a trend toward lower z‐scores in children with higher levels of lesions. Almost all children met their recommended daily intake of calcium. Markers of bone metabolism were normal in all patients. This study demonstrates that reduced BMD is a major complication in children with myelomeningocele. There is a significant relationship with low BMD in children who are wheelchair‐dependent, a trend in those with higher neurological levels, and no relationship between fractures and reduced BMD.
