Cloning and characterization of the gene encoding a blasticidin S acetyltransferase from Streptoverticillum sp.
A gene (bls) encoding a blasticidin S-acetyltransferase from Streptoverticillum sp. JCM4673 was cloned in the Streptomyces plasmid pIJ702 and expressed in S. lividans 1326. Four of the recombinant plasmids contained a common 1129-bp BclI-PstI DNA fragment, which by subcloning experiments was shown to carry the bls gene. Sequencing of the 1129-bp BclI-PstI fragment indicated that it contains two open reading frames of 408 and 366 nucleotides (nt), both starting with ATG and terminating at TGA triplets. Deletion analysis showed that the correct bls sequence is that of 408 nt, whose deduced amino acid sequence conforms to a polypeptide of Mr 15073. A 175-bp DNA fragment from the 5' region of the bls gene had promoter activity in the promoter-probe plasmid pIJ486.

Calcium intake, calcium excretion and blood pressure in adolescents in the upper decile of the distribution: the Torrejon study.
We studied, by dietary recall, the calcium and magnesium intake in 1109 adolescents aged 14-18 years; from 128 we collected a 24-h urine sample to determine electrolyte excretion. Subjects with blood pressure greater than 90th percentile (211) did not consume less calcium or magnesium than those with blood pressure less than 50th (597). Urinary calcium excretion tended to be higher in the adolescents with the highest blood pressure, the difference being statistically significant in males. Urinary sodium excretion also tended to be higher in those adolescents with blood pressure above the 90th percentile than in those with blood pressure below the 50th percentile, the differences being statistically significant in females. A positive significant correlation was found between systolic blood pressure and both calcium and sodium excretion. Our results suggest that hypercalciuria is present in the early phase of hypertension and demonstrate that adolescents at high risk of developing hypertension consume the same amounts of calcium and magnesium as those with low blood pressure.

[Characteristics of falls producing hip fracture in an elderly population. Differences according to age and gender].
BACKGROUND: The majority of hip fractures are produced because of a fall. We examined the characteristics associated with falls causing hip fracture in elderly patients. MATERIAL AND METHODS: Characteristics of falls owing to hip fracture were analyzed in 410 consecutive patients admitted in 6 hospitals during the 2004. We evaluated the location, time and the possible cause of fall: intrinsic risk factor, extrinsic or combined. RESULTS: We evaluated 316 women (77%) and 94 men, mean age 81.9 years. Previous to the hip fracture, the mean BI was 77.5. The mean value of falls during the last year was 1.9. Previously to the fall that caused hip fracture, we found that 24% of the patients had fallen repeatedly (more than two falls). Usually falls were at home (68%) and during daytime (80%). In 45% of patients an intrinsic risk factor was considered the most likely cause, in 33% an extrinsic risk factor and in 22% a combination. CONCLUSIONS: The majority of falls owing to hip fracture in elderly people happen in daytime, at home and due to intrinsic risk factors. Efforts to identify elderly people at risk of fall should be stressed in order to establish preventive measures.

Comparison of anticoagulation clinic patient outcomes with outcomes from traditional care in a family medicine clinic.
BACKGROUND: Giving patients oral anticoagulation therapy in an ambulatory clinic setting is associated with substantial risk of adverse outcomes leading to emergency department visits and unplanned inpatient admissions. This article describes an effectiveness study conducted in a well-characterized family practice setting that compares anticoagulation outcomes in patients managed by a traditional care model with outcomes obtained with an anticoagulation clinic model. METHODS: All study patients received continuous anticoagulation care at the Family Medicine of Southwest Washington (FMSW) clinic during the 1-year study period. The method was retrospective and used linked record review, including outpatient, inpatient, and emergency department records. Patients were divided into two groups as naturally observed: those treated in the clinic by traditional care compared with those treated in an anticoagulation clinic model. Data analyses compared the two groups in terms of patient demographics, anticoagulation control, and inpatient admissions and emergency department visits that were related to clotting or bleeding events. RESULTS: There were no differences in demographic variables between the anticoagulation clinic and traditional care groups. There was a statistically significant difference in anticoagulation control as measured by international normalized ratio (INR) values. The anticoagulation clinic group had fewer INR values outside the target range, +/- 0.1, than the traditional care group (40.4% vs 47.3% P = .022). The anticoagulation clinic group also had significantly fewer INR tests drawn more than 6 weeks apart than the traditional care group (3.7% vs 8.1% P = .01). There was no statistically significant difference in emergency department visit rates caused by adverse events. Inpatient admission rates for the anticoagulation clinic and traditional care groups were not statistically different; however, they were clinically different (4.7 vs 19.7 admissions per 100 patient years of therapy P = .15). CONCLUSIONS: More anticoagulation patients treated by the anticoagulation clinic model at FMSW received an INR test at least every 6 weeks than those treated by the traditional care model, and more of their INR results were within target range +/- 0.1 when compared with the traditional care model.
