Femoral shaft fractures in pediatric patients are treated by elastic intramedullary nailing using titanium or stainless-steel nails. SMIFH2 supplier The elastic stable intramedullary nailing behaves as an internal splint, promoting early mobilization. This type of treatment involves a minimally invasive approach, no damage to the growth plates, and no impairment of femoral head blood supply.

The aim of our study was to identify the negative predicting factors that might lead to an increased complication rate after elastic stable intramedullary nailing of femoral shaft fractures in children.

We conducted a retrospective study on 137 patients with femoral shaft fractures treated by elastic stable intramedullary nailing. Patients' age ranged between 4 and 17years. We used data from the medical records of the patients to evaluate postoperative complications. Plain radiographs were analyzed to determine the fracture type, fracture location, and postoperative complications such as delayed union, angular deformities, and limb length discrepancies. Multivariate analysis was conducted to identify predictors for poor outcomes.

Complications occurred in 29 patients (21%) and consisted of delayed union, axial deformities, or lower limb length discrepancies. In the group of patients that suffered from complications, mechanism of injury, age, and weight were significant. They were older by an average of 5years; half of them weighed more than 50kg and over a half were involved in a road traffic accident.

Elastic nailing is a successful tool to treat femoral shaft fractures. Three factors were demonstrated to influence the outcome. The mechanism of injury, age>11years, and weight>50kg are the most important and are predictors for development of complications such as delayed union or deformity.

Propofol has become the preferred anesthetic in recent years due to its desirable pharmacologic properties. However, propofol possesses a very narrow therapeutic window between the favorable clinical effect and potentially lethal toxicity, therefore, a rapid, simplified, and sensitive liquid chromatography-atmospheric pressure chemical ionization tandem mass spectrometry (LC-APCI-MS/MS) method is presented in this study for the quantification of propofol in human plasma using the isotope-labeled internal standard (IS) of propofol-d17, and then applied in a bioequivalence study.

Sample preparation was accomplished through simple one-step precipitation of plasma protein with acetonitrile. Chromatographic separation was acquired on an ACE Excel 3 Super C

column (2.1 × 50 mm, 3µm) using gradient elution at a flow rate of 0.5mL/min. The MS detection was achieved in the negative ion APCI by multiple reaction monitoring (MRM) mode using the transitions of m/z 177.2 → 161.0 for propofol and m/z 194.2 → 174.2 focts, and there were no serious adverse events during the study.

The method is more simplified and sensitive than the previously reported modes of propofol detection. The two propofol MCT/LCT preparations were considered to be bioequivalent.

This paper analyzes the potential outliers in the bioanalytical and clinical part of a bioequivalence study, the effect on bioequivalence decisions whether or not it is appropriate to eliminate them from the statistical evaluation of bioequivalence.

The clinical part was a cross-over, two periods, two sequences bioequivalence study concerning two piroxicam formulations, on healthy subjects. A simulation study evaluated the influence of 10% errors on the percent bias of calculated concentrations from nominal ones.

In bioequivalence studies, it is not possible to distinguish between relevant types of outliers based only on statistical criteria. The "problem" is particularly acute when the omission of outliers leads to a bias in the decision concerning bioequivalence from rejection to acceptance. In such cases, there is the suspicion of subjective analysis and torture of data. The effect of analytical errors at high plasma levels was criticized for the calculated concentrations in the neighborhood of lowers evaluation of the implications of the decision concerning elimination of outliers on the decision concerning bioequivalence; application of the statistic tests for detection of outliers data; evaluations from the point of view of physiological pharmacokinetics, final decision concerning elimination of outliers.

Perampanel is an approved anti-seizure drug. A new formulation of perampanel fine granules (FG; 1%perampanel) has been developed for patients who are unable to take tablets. Bioequivalence between the 4-mg FG and tablet perampanel formulations, as well as their safety and tolerability, were assessed.

In this phase I, single-center, open-label, 2-period, 2-sequence, crossover, bioequivalence study (NCT03399734), healthy Japanese subjects were randomized to receive single doses of the 4-mg FG perampanel and 4-mg perampanel tablet (separated by a ≥ 6-week washout period). Plasma samples for perampanel concentration analysis were collected pre-dose and at intervals up to 168hours post-dose. The maximum observed concentration (C

) and area under the concentration-time curve from time zero to 168hours (AUC

) were used to assess the bioequivalence of the two formulations.

The 90% confidence intervals (CIs) for the geometric mean ratio of test/reference for C

and AUC

were within the bioequivalence criteria of 80 - 125% (C

90% CI 90.8%, 110%; AUC

90% CI 98.2%, 112%; N = 21). 10/24 (41.7%) subjects with FG experienced ≥ 1 treatment-emergent adverse event (TEAE). The events were mild in severity and resolved within 4hours of onset. There were no deaths, severe TEAEs, serious AEs, or TEAEs leading to study-drug withdrawal.

Bioequivalence of 4-mg FG and 4-mg tablet of perampanel was demonstrated. Both perampanel formulations were generally safe and well tolerated. These data suggest that perampanel FG may be a suitable alternative formulation for patients with epilepsy who have difficulties taking perampanel tablets.

Opioids are commonly used analgesics for moderate to severe pain, but levels of drug effect vary among individuals. As for the mechanisms underlying these individual differences, there have been reports suggesting effects of polymorphisms in the gene encoding μ-opioid receptor (

). However, whether these polymorphisms affect the actions of μ-opioid receptor partial agonists has yet to be determined. This study aimed to assess differences in the pharmacological actions of buprenorphine, a μ-opioid receptor partial agonist, due to a polymorphism (A118G, rs1799971) in the

gene in humans.

Ten healthy adult men (5 with

c.118AA and 5 with

c.118GG) received a single intravenous dose of buprenorphine hydrochloride at 0.001 mg/kg. Blood samples were collected up to 360 minutes after drug administration to assess the pharmacokinetics of buprenorphine. Nociceptive thresholds (temperature), digital symbol substitution test (DSST), and visual analog self-rating scale (VAS) for subjective symptoms were also evaluated over time to assess the pharmacodynamics.

Nociceptive thresholds were significantly increased in the AA as compared to the GG group after buprenorphine administration (p = 0.025), while the DSST scores were significantly lower in the AA group (p < 0.001). The VAS scores for drowsiness (p < 0.001), malaise (p < 0.001), nausea (p < 0.001), and euphoria (p = 0.004) were higher in the AA than in the GG group.

Levels of pharmacological actions of a μ-opioid receptor partial agonist vary in accordance with a polymorphism in the

gene (A118G).

Contrast-induced acute kidney injury (CI-AKI) is a major complication after coronary angiography (CAG) or percutaneous coronary intervention (PCI) and is associated with increased morbidity and mortality. It remains controversial whether renin-angiotensin system (RAS) blockers increase or decrease CI-AKI. In this meta-analysis, we investigated the association between RAS blockers and CI-AKI in patients with normal kidney function or mild-to-moderate chronic kidney disease (CKD).

We performed a systematic search of PubMed, EMBASE, clinicaltrials.gov, and the Cochrane Library up to December 2019 for studies that assessed the association between RAS blockers and CI-AKI events after CAG/PCI. The primary outcome was the development of CI-AKI. Odds ratios (ORs) with corresponding 95% confidence interval (CI) were synthesized.

Five randomized controlled trials (RCTs) and five observational studies were included, accounting for a total of 7,420 patients. Unstratified, RAS blocker administration was significantlthis study did not demonstrate significant evidence, it indicated that clinicians need to be vigilant in assessing the potential risk for RAS blockers to cause CI-AKI in low-risk patients.

There is conflicting data regarding the association of pre-transplant AT1R antibody levels and long-term outcomes following kidney transplantation.

We examined the association between pre-transplant antibodies and long-term graft outcome by assaying pre-transplant sera from 125 kidney transplant recipients from 1999 to 2009.

The mean age at transplant was 55.7±13 years; 67.2% were male, 87.2% were Caucasian, and 67.2% received a deceased donor transplant. Induction therapy included 44.8% thymoglobulin. Human leukocyte antigen (HLA) donor-specific antibodies (DSA) were present in 22 (17.6%) patients, while AT1R antibodies >17U/mL were present in 24 (19.2%). The mean AT1R antibodies level was 13±7.2 U/mL. Patients were followed-up for 7.1±1.9 years after transplant. Pre-transplant AT1R antibodies were associated with rejection (p<0.0001), antibody-mediated rejection (ABMR) (p<0.0001), and death-censored graft failure (DCGF) (p=0.01). This was confirmed by univariate Cox regression analyses for AT1R antibodies >10U/mL (HR 2.64, 95% Cl 1.35 - 5.17, p=0.04) and AT1R antibodies >17U/mL (HR=1.74, 95% Cl 1.061-2.98, p=0.04). Multivariable analyses did not retain AT1R antibodies as independent predictors of DCGF; however, pre-transplant HLA, DSA, and acute rejection during the first year were associated with DCGF (HR 2.07, 95% Cl 1.13 - 3.78, p=0.02 and HR 3.03, 95% Cl 1.13 - 3.78, p=0.0002, respectively).

Our study indicates that in patients with a functioning kidney allograft >5years, pre-transplant AT1R antibodies may be associated with a greater risk of rejection and late graft failure.
