Introduction: Pharmacological poisonings in young children are avoidable. Previous studies report calls to poisons centres, presentations to emergency departments (ED) or hospital admissions. There are limited data assessing concurrent management of poisonings across all three settings. We aimed to describe accidental pharmacological poisonings in young children across our Poisons Information Centre (PIC), EDs and hospitals.
Methods: A population-based study in New South Wales, Australia, of PIC calls, ED presentations and hospital admissions for accidental pharmacological poisoning in children aged <5 years, 2007–2013. We examined trends, medicines responsible and subsequent management. Medicines were coded using ICD10-AM diagnosis codes (T36-50).
Results: Over 2007–2013, pharmacological poisonings accounted for 67,816 PIC calls, 7739 ED presentations and 2082 admissions. Rates (per 10,000 children) of PIC calls declined from 220 to 178; ED presentations were stable (~22–24), with a decrease in emergency cases offset by an increase in semi- or non-urgent presentations; hospital admissions declined (8–5). Most PIC calls related to “non-opioid analgesics” (25%), and “topical agents” (18%). Nearly every day, one child aged <5 years was admitted to hospital for poisoning. “Benzodiazepines”, “other and unspecified antidepressants”, “uncategorised antihypertensives”, and “4-aminophenol derivatives” accounted for over one-third of all admissions. Most PIC calls (90%) were advised to stay home, 6% referred to hospital. One-quarter of ED presentations resulted in admission.
Conclusions: Poisonings reported to PIC and hospitals declined, however, non-urgent ED presentations increased. Strategies to reduce therapeutic errors and access to medicines, and education campaigns to improve Poisons Centre call rates to prevent unnecessary ED presentations are needed. 相似文献
Impaired strength adversely influences an older person’s ability to perform activities of daily living. A cross-sectional study of 117 independently living men and women (age = 73.4 ± 9.4 year; body mass index (BMI) = 27.6 ± 4.8 kg/m2) aimed to assess the association between body composition and: (1) upper body strength (handgrip strength, HGS); (2) lower extremity performance (timed up and go (TUG) and sit to stand test (STS)); and (3) endurance (6-minute walk (SMWT). Body composition (% fat; lean body mass (LBM)) was assessed using bioelectrical impedance. Habitual physical activity was measured using the Minnesota Leisure Time Physical Activity Questionnaire (MLTPA) and dietary macronutrient intake, assessed using 24 h recalls and 3-day food records. Regression analyses included the covariates, protein intake (g/kg), MLTPA, age and sex. For natural logarithm (Ln) of right HGS, LBM (p < 0.001) and % body fat (p < 0.005) were significant (r2 = 46.5%; p < 0.000). For left LnHGS, LBM (p < 0.000), age (p = 0.036), protein intake (p = 0.015) and LnMLTPA (p = 0.015) were significant (r2 = 0.535; p < 0.000). For SMW, % body fat, age and LnMLTPA were significant (r2 = 0.346; p < 0.000). For STS, % body fat and age were significant (r2 = 0.251; p < 0.000). LBM is a strong predictor of upper body strength while higher % body fat and lower physical activity are associated with poorer outcomes on tests of lower extremity performance. 相似文献
Dietary intakes of sodium and potassium are important determinants of blood pressure. We assessed sodium and potassium intake in a cross-sectional survey which included a random sample of New Zealand Adults aged 18 to 64 years from two New Zealand cities: Dunedin and Wellington. Participants completed a short questionnaire, had height, weight and blood pressure measured, and collected a 24 h urine sample. Mean 24 h sodium excretion was 3386 mg/day (95% CI 3221, 3551): 3865 mg/day for men and for 2934 mg/day women. Mean 24 h potassium excretion was 2738 mg/day (95% CI 2623, 2855): 3031 mg/day for men and 2436 mg/day for women. Mean sodium:potassium ratio was 1.32 (95% CI 1.26, 1.39); 1.39 for men and 1.26 for women. Sodium intake was higher among younger people, men, those with a higher BMI and higher potassium excretion. Potassium excretion was higher among older people, men and those with a higher sodium excretion. New Zealand adults have high sodium intakes and low potassium intakes compared to recommended levels. This is likely to adversely affect population blood pressure levels as well as incidence of cardiovascular disease. A comprehensive public health programme to reduce dietary sodium intake and increase intake of fruit and vegetables is warranted. 相似文献
Summary: In 1505 patients with acute myocardial infarction (Ml) pericarditis was diagnosed most often in those with anterior transmural ECG changes. Those with pericarditis had a significantly greater hospital mortality and peak serum lactic dehydrogenase (LDH) levels and a greater incidence of left ventricular failure (LVF). The patients reported here1 and our methods of study2, 4 have been described. 相似文献
We have shown an age-associated increase in plasma osmolality (p less than 0.001) in 152 randomly selected subjects, living in the community. In the old [mean age 78.0 (7.5) years] the plasma osmolality was 302.2 (300.6-303.8) mOsmol/kg compared with 291.2 (290.0-292.3) mOsmol/kg in the young [39.2 (11.2) years] (p less than 0.0001). In a further group of 20 screened, health status defined, elderly subjects the plasma osmolality was 298.1 (295.9-300.3) mOsmol/kg, which was significantly higher than the young group (p less than 0.0001) but lower than the unscreened old subjects (p = 0.005). The variance was also significantly lower (p = 0.03). The results may reflect a loosening of homoeostatic control and highlight the need for care in subject selection in studies of ageing. 相似文献
Summary The hypothesis that nerves in diabetes mellitus exhibit an increased susceptibility to compression was experimentally tested.
Inhibition of fast axonal transport was induced by local compression in sciatic nerves of rats with streptozotocin-induced
diabetes mellitus. Fast anterograde axonal transport was measured after application of3H-leucine to the motor neurone cell bodies in the spinal cord. The sciatic nerve as subjected to local, graded compression
in vivo by a small compression chamber. The amount of accumulation of proteins was quantified by calculation of a transport
block ratio. Compression at 30 mm Hg for 3 h induced a significantly greater (p<0.05) accumulation of axonally transported proteins at the site of compression in nerves of diabetic animals (transport block
ratio: 1.01±0.35; n=7) than in nerves of controls (0.67±0.16;n=7). Accumulation was significantly higher in ligature experiments of both control (1.34±0.44;n=8;p< 0.01) and diabetic animals (1.45±0.30;n=8 ;p< 0.05), indicating that the block of transport in compressed nerves was incomplete. Neither sham compressed diabetic (0.50±0.09;n=6) nor control (0.49±0.11;n=6) nerves showed any block of axonal transport. The possible causes of the increased inhibition of fast axonal transport
in diabetic rats are discussed. The results indicate that diabetes may lead to an increased susceptibility of peripheral nerves
to compression. 相似文献
