摘要:
A retrospective investigation was conducted to determine if acute ethanol (EtOH) ingestion before injury leads to hematologic impairment as noted by coagulation and transfusion parameters. Patients older than 18 years of age were grouped according to the presence or absence of detectable EtOH concentrations in the blood, with further subdivision based on an Injury Severity Score of 8 or less or 9 or more. The following direct and indirect indicators of hematologic function were studied: volume of resuscitation fluids administered (including blood products), prothrombin time, partial thromboplastin time, and hematocrit. Of the 304 patients who were evaluated, 152 had detectable EtOH concentrations and 136 had andetectable EtOH concentrations; 16 patients had not been tested for blood EtOH concentrations and were excluded from the analysis. There were no significant differences between groups with regard to blood or fluid requirements or coagulation parameters. Detectable blood EtOH concentrations in trauma patients are not associated with significant changes in transfusion requirements or coagulation parameters compared to patients without detectable EtOH concentrations.

摘要:
This placebo-controlled randomized trial was conducted to ascertain the value of calcium citrate supplementation in averting bone loss in 63 postmenopausal women, 57 of whom were early postmenopausal (five years after menopause) and six of whom were mid-postmenopausal (five to ten years after menopause). Bone density data were available for 25 women who took 800 mg of calcium citrate daily and 31 women who received placebo for one to two years. The two groups were similar in baseline age, years postmenopause (3.3 in the calcium citrate group vs 2.7 in the placebo group), height, weight, calcium intake, and L2-L4 bone density. L2-L4 bone density did not change during calcium citrate treatment (+1.03% after two years), whereas it declined significantly by −2.38% after two years on placeboP< .001). Femoral neck bone density did not change in either group. Radial shaft bone density did not change in the calcium citrate group (-0.02% after two years), but it declined significantly in the placebo group (-1.79% after one year and −3.03% after two years,P< .01). The difference in bone density of the L2-L4 vertebrae and radial shaft after two years of treatment was significant between the two groups. An analysis of covariance disclosed no significant effect of calcium citrate on L2-L4 bone density during the first three years after menopause, but a protective effect after three years.Although serum PTH did not change, serum and urinary calcium increased and serum calcitriol and urinary phosphorus decreased in the calcium citrate group, indicative of parathyroid suppression. Serum bone-specific alkaline phosphatase and osteocalcin, and urinary hydroxyproline and N-tetopeptide decreased during some calcium citrate treatment periods, indicative of a reduction in bone turnover. Thus, calcium citrate supplementation (400 mg of calcium twice daily) averted bone loss and stabilized bone density in the spine, femoral neck, and radial shaft in women relatively soon after menopause. This bone-sparing action was probably due to the inhibition of bone resorption from parathyroid suppression.

摘要:
Objective.To perform a meta-analysis of data from available published trials comparing the bio-availability of calcium carbonate with that of calcium citrate.Data sources.The whole set was comprised of 15 studies involving 184 subjects who underwent measurement of calcium absorption from calcium carbonate and calcium citrate. Category A excluded four studies for lack of physiological relevance, use of a mixed preparation with low content of calcium carbonate, or wide variability in results. Category B was comprised of five studies (from Category A) involving 71 subjects who took calcium supplements on an empty stomach. Category C was comprised of six studies (from Category A) involving 65 subjects who took calcium preparations with meals.Method.The meta-analysis of calcium absorption data from calcium carbonate and calcium citrate, with calculation of effect size and 95% confidence intervals.Results.Calcium absorption from calcium citrate was consistently significantly higher than that from calcium carbonate by 20.0% in the whole set, by 24.0% in Category A, by 27.2% on an empty stomach, and by 21.6% with meals.Conclusion.Calcium citrate is better absorbed than calcium carbonate by approximately 22% to 27%, either on an empty stomach or co-administered with meals.

摘要:
Injectable gallium (Ga) nitrate, approved in the United States for the treatment of hypercalcemia of malignancy, has been known for more than 2 decades to have immunosuppressive properties. At therapeutic doses, it has few adverse effects, although high-dose infusions may result in severe nephrotoxicity, particularly in patients who are not adequately hydrated, and severe anemia. In animal models, Ga has been shown to have efficacy in the treatment of adjuvant arthritis, type 1 diabetes, experimental autoimmune encephalomyelitis, experimental pulmonary inflammation, cardiac allograft rejection, experimental autoimmune uveitis, endotoxic shock, and systemic lupus erythematosus. Clinical trials have demonstrated efficacy in Paget's disease of bone and activity against some malignancies, including epithelial ovarian carcinoma, non-squamous cell carcinoma of the cervix, bladder cancer, and non-Hodgkin's lymphoma. Other clinical trials underway include studies of sarcoidosis and rheumatoid arthritis. Future studies should be conducted not only in other autoimmune diseases, such as multiple sclerosis, but also in graft-versus-host disease, leprosy, and acquired immunodeficiency syndrome (AIDS).

摘要:
The geriatric population accounts for over 12% of the United States population and consumes over 25% of all prescription medications. Polypharmacy and patient noncompliance are often encountered in caring for these patients. These issues along with a variety of age-related physiologic changes and the presence of multiple medical illnesses place the elderly at an increased risk for adverse drug reactions. Especially worrisome is the use of long-acting benzodiazepines and anti-cholinergic medications in this population. The problem of adverse drug reactions is a common clinical problem that is of great public concern as the number of older persons in the United States continues to grow. In response, a variety of proactive measures have been developed. These measures include the development of consensus criteria for inappropriate medications, federal government regulation, expansion of the role of clinical pharmacists, and computer-assisted prescribing protocols.
