Objective
To evaluate the non-inferiority of a lower therapeutic dose (300,000 IU) in comparison to standard dose (600,000) IU of Vitamin D for increasing serum 25(OH) D levels and achieving radiological recovery in nutritional rickets.Design
Randomized, open-labeled, controlled trial.Setting
Tertiary care hospital.Participants
76 children (median age 12 mo) with clinical and radiologically confirmed rickets.Intervention
Oral vitamin D3 as 300,000 IU (Group 1; n=38) or 600,000 IU (Group 2; n=38) in a single day.Outcome variables
Primary: Serum 25(OH)D, 12 weeks after administration of vitamin D3; Secondary: Radiological healing and serum parathormone at 12 weeks; and clinical and biochemical adverse effects.Results
Serum 25(OH)D levels [geometric mean (95% CI)] increased significantly from baseline to 12 weeks after therapy in both the groups [Group 1: 7.58 (5.50–10.44) to 16.06 (12.71–20.29) ng/mL, P<0.001]; Group 2: 6.57 (4.66–9.25) to 17.60 (13.71–22.60, P<0.001]. The adjusted ratio of geometric mean serum 25(OH)D levels at 12 weeks between the groups (taking baseline value as co-variate) was 0.91 (95% CI: 0.65–1.29). Radiological healing occurred in all children by 12 weeks. Both groups demonstrated significant (P<0.05) and comparable fall in the serum parathormone and alkaline phosphatase levels at 12 weeks. Relative change [ratio of geometric mean (95% CI)] in serum PTH and alkaline phosphatase, 12 weeks after therapy, were 0.98 (0.7–1.47) and 0.92 (0.72–1.19), respectively. The serum 25(OH)D levels were deficient (<20 ng/mL) in 63% (38/60) children after 12 weeks of intervention [Group 1: 20/32 (62.5%); Group 2: 18/28 (64.3%)]. No major clinical adverse effects were noticed in any of the children. Hypercalcemia was documented in 2 children at 4 weeks (1 in each Group) and 3 children at 12 weeks (1 in Group 1 and 2 in Group 2). None of the participants had hypercalciuria or hypervitaminosis D.Conclusion
A dose of 300,000 IU of vitamin D3 is comparable to 600,000 IU, administered orally, over a single day, for treating rickets in under-five children although there is an unacceptably high risk of hypercalcemia in both groups. None of the regime is effective in normalization of vitamin D status in majority of patients, 3 months after administering the therapeutic dose. 相似文献32.

This study aims to prospectively evaluate the ultrasound appearance of the normal Lisfranc’s ligament in 50 patients (100 ft) with no prior or current ligament injury. Fifty normal asymptomatic patients between the ages of 18 and 80 years were assessed. Three key features were recorded: ultrasound appearance, thickness, and length of the Lisfranc’s ligament. Patients excluded from this study included pediatric patients and those with history of injury or symptoms related to the foot. The mean right- and left-sided ligament (RT) thickness were 0.096 (0.021) and 0.104 (0.023), respectively. The mean right- and left-sided ligament RT length was 0.54 (0.11) and 0.57 (0.11), respectively. The appearance of the ligament was similar in all patients with a central thin band of hypoechogenicity lined by hyperechoic lines on either side. Understanding the normal appearance, thickness, and length of the Lisfranc’s ligament in a large sample is imperative to diagnose abnormal appearances of this ligament including sprains and tears by ultrasound. Ultrasound, with its easy accessibility, can be used in the emergency department to rapidly exclude injury of the ligament. Increased understanding and awareness of the Lisfranc’s ligament on ultrasound can allow for more accurate diagnosis and treatment. 相似文献

The authors investigated the effectiveness and specificity of the Penn Resiliency Program (PRP; J. E. Gillham, L. H. Jaycox, K. J. Reivich, M. E. P. Seligman, & T. Silver, 1990), a cognitive-behavioral depression prevention program. Children (N = 697) from 3 middle schools were randomly assigned to PRP, Control (CON), or the Penn Enhancement Program (PEP; K. J. Reivich, 1996; A. J. Shatté, 1997), an alternate intervention that controls for nonspecific intervention ingredients. Children's depressive symptoms were assessed through 3 years of follow-up. There was no intervention effect on average levels of depressive symptoms in the full sample. Findings varied by school. In 2 schools, PRP significantly reduced depressive symptoms across the follow-up relative to both CON and PEP. In the 3rd school, PRP did not prevent depressive symptoms. The authors discuss the findings in relation to previous research on PRP and the dissemination of prevention programs. 相似文献

In 1978, Jonathan Sprent and Robert Korngold proved that graft-versus-host disease (GVHD) is caused by donor T cells that attack the host's non-MHC antigens. T cell depletion of donor grafts has since become a staple of transplantation strategies to combat leukemia and other inherited blood disorders. 相似文献

BACKGROUND: Intermediate care (IC) services have been widely introduced in England and have the strategic objectives of reducing hospital and long-term care use. There is uncertainty about the clinical outcomes of these services and whether their strategic aims will be realised. SETTING: A metropolitan city in northern England. DESIGN: A quasi-experimental study comparing a group of older people before and after the introduction of an IC service. A quota sampling method was used to match the groups. SUBJECTS: Patients presenting as emergency admissions to two elderly care departments with falls, confusion, incontinence or immobility. Intervention: a city-wide service in which a joint care management team (multi-agency, multi-disciplinary) assessed patient need and purchased support and rehabilitation from sector-based IC teams. OUTCOMES: Nottingham Extended Activities of Daily Living score, Barthel Index, Hospital Anxiety and Depression score, mortality, readmission to hospital, and new institutional care placement at 3, 6 and 12 months post-recruitment. RESULTS: There were 800 and 848 patients, respectively, in the control and intervention groups. Clinical outcomes, hospital and long-term care use were similar between the groups. Uptake of IC was lower than anticipated at 29%. An embedded case-control study comparing the 246 patients who received IC with a matched sample from the control group demonstrated similar clinical outcomes but increased hospital bed days used over 12 months (mean +8 days; 95% CI 3.1-13.0). CONCLUSION: This city-wide IC service was associated with similar clinical outcomes but did not achieve its strategic objectives of reducing long-term care and hospital use. 相似文献

A 290-kilobase-pair chromosomal segment containing the genes encoding the human class I major histocompatibility complex molecules HLA-B and HLA-C as well as a class I pseudogene has been isolated on three overlapping yeast artificial chromosome (YAC) clones. One YAC clone contains both the HLA-B and HLA-C genes. These loci are located approximately 85 kilobase pairs apart, each in close association with a CpG island. Southern blotting and nucleotide sequencing showed no evidence of alteration of the structure of the cloned DNA in the YACs. End fragments from the YAC inserts have been isolated and used to confirm the overlaps between clones. These fragments can also serve as polymorphic markers for structural analysis of the major histocompatibility complex. Our data show that YAC cloning offers an attractive alternative for analysis of the structures of large gene complexes such as HLA. 相似文献

BackgroundSeveral Medicaid programs have implemented approaches to ensure the appropriateness of opioid utilization and decrease opioid dispensing.ObjectiveTo evaluate whether Medicaid opioid harm reduction strategies (OHRS) resulted in a decrease in opioid claims, costs, or units reimbursed per beneficiary.MethodsThe number of OHRS was determined for each state's fee-for-service (FFS) Medicaid program according to previously published data. Publically available FFS Medicaid data were tabulated by state for opioid claims, costs, and units reimbursed in state fiscal years 2016 and 2017. Multivariable generalized estimating equation (GEE) models were utilized to analyze the data.ResultsGEE results indicated that OHRS intensity or change in OHRS did not impact opioid claims or units reimbursed in Medicaid FFS programs. A significant finding on reduction in beneficiary-adjusted opioid costs was observed for states with two OHRS compared to states with no OHRS. There were no significant differences in opioid claims, units reimbursed, and costs based on states with 3 or fewer OHRS versus those with four or more. When examining the differential effect of each individual type of OHRS, there were no significant differences in opioid claims, units reimbursed, nor medication costs.ConclusionsThe number of OHRS may not be associated with opioid dispensing or utilization in FFS Medicaid programs. Other factors may have led to the decrease in opioid claims for Medicaid. 相似文献
