Abstract
BACKGROUND We hypothesized that the time to successful fibreoptic tracheal intubation through the nasal route would be faster than the oral route for both experts and trainees in children <2 yr of age. METHODS One hundred children, 24 months and under in age, were randomized to an operator (expert or trainee), and route (nasal or oral) for fibreoptic tracheal intubation. Three separate times were then measured: (i) time to first glottic view, (ii) time to carinal view, and (iii) total time to successful tracheal intubation. The number of attempts made, manoeuvres needed to obtain an adequate laryngeal view, and manoeuvres for tracheal tube passage were also recorded. RESULTS Time to successful tracheal intubation was significantly faster for experts than trainees. There was no difference in the time to tracheal intubation between the nasal and oral routes for experts. In trainees, intubation times were shorter for the nasal route-median (inter-quartile range) time (s) to carinal view was 35 (27-63) for the nasal route vs 59 (38-94) for the oral route (P=0.03), and the median time to successful tracheal intubation were 62 (49-122) vs 117 (61-224), P=0.05, for the nasal and oral routes, respectively. For trainees, the oral route required a greater number of airway manoeuvres for adequate laryngeal views and passage of the tracheal tube compared with the nasal route. CONCLUSIONS For clinicians with less experience in using paediatric bronchoscopes, fibreoptic tracheal intubation through the nasal route may be a more straightforward process than the oral route in children <2 yr of age.

Abstract
In multiple quantitative trait locus (QTL) mapping, a high-dimensional sparse regression model is usually employed to account for possible multiple linked QTLs. The QTL model may include closely linked and thus highly correlated genetic markers, especially when high-density marker maps are used in QTL mapping because of the advancement in sequencing technology. Although existing algorithms, such as Lasso, empirical Bayesian Lasso (EBlasso) and elastic net (EN) are available to infer such QTL models, more powerful methods are highly desirable to detect more QTLs in the presence of correlated QTLs. We developed a novel empirical Bayesian EN (EBEN) algorithm for multiple QTL mapping that inherits the efficiency of our previously developed EBlasso algorithm. Simulation results demonstrated that EBEN provided higher power of detection and almost the same false discovery rate compared with EN and EBlasso. Particularly, EBEN can identify correlated QTLs that the other two algorithms may fail to identify. When analyzing a real dataset, EBEN detected more effects than EN and EBlasso. EBEN provides a useful tool for inferring high-dimensional sparse model in multiple QTL mapping and other applications. An R software package 'EBEN' implementing the EBEN algorithm is available on the Comprehensive R Archive Network (CRAN).

Abstract
This review summarises most currently used indices to assess and monitor patients with systemic lupus erythematosus (SLE) in clinical trials, long-term observational studies, and clinical care. Six SLE disease activity indices include the British Isles Lupus Assessment Group Index (BILAG), European Consensus Lupus Activity Measurement (ECLAM), Systemic Lupus Activity Measure (SLAM), Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), Lupus Activity Index (LAI), and Systemic Lupus Erythematosus Activity Questionnaire (SLAQ). Three SLE responder indices include Responder Index for Lupus Erythematosus (RIFLE), SLE Responder Index (SRI), and BILAG Based Combined Lupus Assessment (BICLA). Three SLE damage indices include the Systemic Lupus International Collaborating Clinics/American College of Rheumatology-Damage Index (SLICC/ACE-DI), Lupus Damage Index Questionnaire (LDIQ), and Brief Index of Lupus Damage (BILD). The SLAQ, LDIQ and the BILD are patient self-report questionnaires, which appear to give similar information to physician-completed indices, but are pragmatically more easily completed as patients do almost all the work. Additional self-report indices which have been used to assess and monitor patients with in SLE include a generic general health short form 36 (SF36), a SLE-specific Lupus Patient Reported Outcome (LupusPRO), and a generic rheumatology index, Routine Assessment of Patient Index Data 3 (RAPID3). These activity, response, damage and patient self-report indices have been validated at different levels with no consensus about what it is the most appropriate for every setting. Sensitive and feasible assessment of SLE in clinical trials, observational studies, and busy clinical settings remains a challenge to the rheumatology community.

Abstract
The aim of the study was to investigate and compare the clinical manifestations between HLA-B27(+) and HLA-B27(-) ankylosing spondylitis (AS) patients in order to obtain knowledge of the impact of HLA-B27 status on AS, and to inform clinical treatment. A nationwide epidemiological investigation was performed from November 2008 to October 2010. The demographic data and clinical characteristics, and the status of HLA-B27 were collected using questionnaires and laboratory assay, respectively. A total of 2144 patients (78.5% males and 78.4% HLA-B27(+) AS patients) participated in this study. The percentages of males, patients with family history, and involvement of lumbar spine, thoracic spine and hip joints, were observed to be significantly higher in the HLA-B27(+) AS patients than in their HLA-B27(-) AS peers.

Meta-analysis on the efficacy and tolerability of the augmentation of antidepressants with atypical antipsychotics in patients with major depressive disorder. ACTA ACUST UNITED AC 2014; 47:605-16.

Abstract
We assessed the efficacy and tolerability of the augmentation of antidepressants
(ATDs) with atypical antipsychotics (AAPs) to treat patients with major depressive
disorder. A retrograde study to identify relevant patient data included databases of
PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Database of
Abstracts of Reviews of Effects. Data from 17 trials, involving 3807 participants,
were identified. The remission rate (RR) and overall response rate (ORR) of
adjunctive treatment with AAPs were significantly higher than placebo treatment:
RR=1.90 (95%CI=1.61-2.23, z=7.74, P<0.00001) and ORR=1.68 (95%CI=1.45-1.94,
z=7.07, P<0.00001). We found that the short-term (4 weeks) treatment [ORR=1.70
(95%CI=0.98-2.95, Z=1.89, P=0.06)] was significantly different from the long-term
(6-12 weeks) treatment [ORR=1.68 (95%CI=1.45-1.94, z=7.07, P<0.00001)]. No
significant difference in ORR was observed between groups with or without sedative
drugs. The discontinuation rate due to adverse effects was higher for adjunctive
treatment with AAPs: ORR=3.32 (95%CI=2.35-4.70, z=6.78, P<0.00001). These results
demonstrate that the augmentation of ATDs with AAPs (olanzapine, quetiapine,
aripiprazole, and risperidone) was more effective than a placebo in improving
response and remission rates, although associated with a higher discontinuation rate
due to adverse effects.

Abstract
Abstract
Various components of the phosphatidylinositol 3-kinase (PI3K) pathway are deregulated across a spectrum of human cancers. Notably, cancers with PIK3CA mutations, seen in roughly 30% of breast cancers, are amongst the most sensitive to PI3K inhibitors (PI3Ki) as single agents. Therefore, there have been great efforts to develop PI3K inhibitors specifically for these types of cancers, and many agents have already entered the clinic.
Although initial responses and prolonged stable disease have been observed, resistance frequently emerges. Moreover, there is a subset of PIK3CA mutated cancers that unexpectedly do not exhibit an initial response or disease stabilization upon exposure to PI3K inhibitors, despite presence of the mutation. These cancers are said to have de novo resistance to PI3K inhibition. To determine methods of overcoming resistance to PI3K inhibitors, we generated two models with acquired resistance to the p110a isoform specific inhibitor BYL-719 (BYL) using MDA-MB-453 (453) and T47D. We also established one model of resistance to the pan-PI3K inhibitor GDC-0941 using MCF7 cells. These lines were chosen because of their PIK3CA mutated status and sensitivity to PI3K inhibition. Each cell line was grown in increasing concentrations of PI3K inhibitor until the cells proliferated readily at a dose of drug that effectively reduced cell viability and inhibited pAKT in the sensitive parental cell lines. Interestingly, both BYL resistant cells (453R and T47DR) were cross resistant GDC and the MCF7R line was refractory to BYL.
To elucidate mechanisms to overcome resistance to PI3K inhibitors, we undertook a combinatorial drug screen, in which PI3K inhibitor resistant cells were treated with escalating doses of a panel of 45 targeted agents, both in the presence and absence of a fixed dose of PI3Ki, to determine which agents synergized effectively with PI3K inhibition in these resistant cells. We observed in each of the three PI3Ki resistant models a synergy between the CDK4/6 inhibitor LEE-011 and PI3K inhibition. We furthermore tested this combination of agents in a PIK3CA mutated breast cancer model with de novo resistance to PI3K inhibitors, CAL51, and again noted efficacy with the combination of GDC and LEE-011 while either agent on its own displayed minimal activity.
To determine whether addition of CDK 4/6 inhibition might be an effective addition to PI3Ki in the upfront setting in vivo, we injected each of the PIK3CA mutated lines MCF7, 453, and T47D into female nude mice and treated with vehicle, BYL, LEE-011, or the combination. We noted in each of the three models that the combination of agents, led to tumor regression that was more substantial than single agent treatment, and furthermore delayed the acquisition of resistance relative to single agent therapy. We furthermore tested GDC with LEE-011 singly and in combination in both MCF7 and CAL51 xenografts and again noted that the combination of agents led to tumor regression, whereas in these instances, single agent treatment did not.
We conclude that the combination of PI3K and CDK 4/6 inhibition may be an effective strategy for treating PIK3CA mutated breast cancer and deserves further study in the clinical setting.

Risk of kidney stones with surgical intervention in living kidney donors. Am J Transplant 2013; 13:2935-44.

Abstract
A kidney stone in a person with a solitary kidney requires urgent attention, which may result in surgical and/or hospital attention. We conducted a matched retrospective cohort study to determine if living kidney donors compared to healthy nondonors have a higher risk of: (i) kidney stones with surgical intervention, and (ii) hospital encounters for kidney stones. We reviewed all predonation charts for living kidney donations from 1992 to 2009 at five major transplant centers in Ontario, Canada, and linked this information to healthcare databases. We selected nondonors from the healthiest segment of the general population and matched 10 nondonors to every donor. Of the 2019 donors and 20 190 nondonors, none had evidence of kidney stones prior to cohort entry. Median follow-up time was 8.4 years (maximum 19.7 years; loss to follow-up <7%). There was no difference in the rate of kidney stones with surgical intervention in donors compared to nondonors (8.3 vs. 9.7 events/10 000 person-years; rate ratio 0.85; 95% confidence interval [CI] 0.47-1.53). Similarly there was no difference in the rate of hospital encounters for kidney stones (12.1 vs. 16.1 events/10 000 person-years; rate ratio 0.75; 95% CI 0.45-1.24). These interim results are reassuring for the safety of living kidney donation.

Abstract
BACKGROUND AND PURPOSE Carotid blowout is a serious late complication of prior treatment of advanced head and neck cancer. We evaluate the efficacy of CTA in the diagnosis of impending carotid blowout syndrome in patients with head and neck cancer, and its capability to predict clinical outcome. MATERIALS AND METHODS The clinical data of 29 patients with impending carotid blowout who underwent CTA were collected and analyzed. Imaging signs included tissue necrosis, exposed artery, viable perivascular tumor, pseudoaneurysm, and contrast extravasation. DSA was obtained in 20 patients. One-year outcomes were compared based on management. RESULTS The most common CTA finding was necrosis (94%), followed by exposed artery (73%), viable tumor (67%), pseudoaneurysm (58%), and contrast extravasation (30%). Exposed artery, pseudoaneurysm, and contrast extravasation were the 3 CTA findings related to outcomes. All of the pseudoaneurysm and contrast extravasation cases were associated with an exposed artery. An exposed artery was the most important prognostic predictor and could not be diagnosed on DSA. Patients without the 3 findings on CTA (group 1) had the best survival rate at 1-year follow-up, followed by patients with the 3 findings treated immediately by permanent artery occlusion (group 2). Patients with the 3 findings who had no immediate treatment (group 3) had the worst outcomes (P < .001 in group 1 vs group 3 and group 2 vs group 3; P = .056 group 1 vs group 2). CONCLUSIONS CTA, with its ability to diagnose an exposed artery compared with DSA, may offer important management and prognostic information in patients with impending carotid blowout.

Abstract
OBJECTIVE We introduce a new laparoscopic cholecystectomy by using 2-mm needle-shape instruments and compare it with single-incision laparoscopic cholecystectomy. PATIENTS AND METHODS From January 2011 to June 2011, 60 patients who satisfied the inclusion and exclusion criteria were prospectively selected and randomized to receive either a scar-hidden novel laparoscopic cholecystectomy (NLC group) (n=30) or a single-incision laparoscopic cholecystectomy (SILC group) (n=30). Their operation time, pain score, and satisfaction score were contrasted. RESULTS All operations were successful. Two patients were converted to conventional three-port laparoscopic cholecystectomy in the SILC group. No postoperative complications occurred in both groups. The operation time was significantly lower in the NLC group (14.17±3.51 minutes in the NLC group versus 24.67±4.12 minutes in the SILC group, P<.01). As to the satisfaction score, the NLC group was superior to the SILC group (4.53±0.57 in the NLC group versus 4.07±0.52 in the SILC group P<.01). There was also a lower postoperative pain score in the NLC group, although the results did not reach statistical significance. CONCLUSIONS The new scar-hidden laparoscopic cholecystectomy is a safe and feasible technique. Compared with single-incision laparoscopic cholecystectomy, it has a lower operation time and less difficulty but a higher satisfaction score. It demonstrates a new approach for minimal invasive surgery.

Abstract
Activation of specific oncogenes and inactivation of tumor suppressor genes play major roles in mechanisms leading to neoplastic transformation. The potential involvement of these genes in determining genome stability is an important issue. To examine the relationships between altered oncogene expression and the effects on genome stability, we have investigated the drug sensitivity properties of mouse 10T1/2 fibroblasts transfected with combinations of H-ras, c-myc and the proline 193 mutant form of p53. The relative colony forming efficiencies of these cells were investigated in the absence or presence of various concentrations of the chemotherapeutic agents, methotrexate, N-(phosphonacetyl)-L-aspartate (PALA) or hydroxyurea. The effects of altered oncogene expression were found to be drug and locus specific, and to lead to increased drug resistance (e.g. H-ras transfectants were significantly resistant to methotrexate or PALA), decreased drug resistance (e.g. H-ras/-myc transfectants were significantly less resistant to PALA or hydroxyurea than H-ras transfected cells), or to no significant change in drug sensitivity (e.g. H-ras transfected cells were not significantly different in sensitivity to hydroxyurea than non-transfected cells). Gene amplification was an important but not the only mechanism for drug resistance. Cells that were transfected with p53 (H-ras/p53 or H-ras/c-myc/p53) exhibited the greatest drug resistance properties with all three chemotherapeutic agents, in keeping with the important role of p53 in DNA repair and DNA amplification mechanisms. Although both H-ras/p53 and H-ras/c-myc/p53 groups exhibited very similar genome stability characteristics as determined by drug sensitivity results, they were significantly different in their abilities to produce transformed foci in vitro and lung metastases in vivo. The H-ras/c-myc/p53 transfected cells formed significantly higher numbers of transformed foci and exhibited a greater malignant potential. These results are consistent with observations that H-ras expression directly correlates with malignant potential, and that H-ras/c-myc/p53 transfected cells have higher H-ras expression than H-ras/p53 transfected cells. Alterations in genomic integrity through changes in onocogene expression play important roles in mechanisms determining drug sensitivity; in addition to genome destabilization, other events are critically involved in regulating transformed and malignant characteristics.
