Introduction

First-line targeted therapies have been developed for advanced non–small-cell lung cancer (NSCLC). However, small biopsy samples pose a challenge to testing all relevant biomarkers. The present study characterized clinician-ordered single-gene lung cancer testing and evaluated tissue stewardship and the ability to successfully determine mutation status with single-gene testing or investigational use of the Oncomine Dx Target Test.

Materials and Methods

Clinician-submitted orders for 3659 single-gene tests (EGFR, ALK, ROS1, BRAF, KRAS, ERBB2, MET, RET, FGFR1) across 1402 samples at a large US-based commercial reference laboratory and 169 investigational Oncomine Dx Target Tests were retrospectively evaluated. The testing success rates and tissue consumption were evaluated by sample type, test type, and number of single-gene tests per sample.

Results

The large majority of lung tissue samples submitted for clinical testing were small (70.5% core needle biopsies; 10.0% fine needle aspirations). With single-gene testing, mutation status was successfully reported for ≥ 1 biomarker for 88.4% of the clinical samples. The success rates decreased and tissue consumption increased with testing of additional biomarkers. Investigational Oncomine Dx Target Tests were permitted 1 tissue slide each and demonstrated success rates similar to single-gene testing for ≥ 5 biomarkers on core needle biopsies, ≥ 4 biomarkers on fine needle aspirations, and ≥ 2 biomarkers on surgical resection specimens.

Conclusion

Tissue stewardship is important to enable successful completion of genetic testing and informed NSCLC treatment decisions. Preliminary assessment of the investigational Oncomine Dx Target Test suggests it could facilitate access to multiple biomarker testing using small tissue samples to support therapy decisions for patients with advanced NSCLC.  相似文献

‘Revenge porn’ or ‘cyber rape’ occurs when intimate images that were previously sent with permission are leaked to a wider audience without consent. This research investigated the perceptions that individuals form about ‘revenge porn’ victims, aiming to gain more understanding from a victimisation perspective as a first step towards improving victim outcomes. One hundred and twenty-two individuals were presented with a scenario depicting a leaked intimate image with a female victim. Two distinct nudity levels: low (lingerie) and high (bare-chest, breasts exposed) were included, and participants’ responses to the Sexual Double Standards Scale were analysed to determine whether acceptance of the traditional sexual double standard was correlated with victim perception. Results indicated that victims were perceived as more promiscuous and more blameworthy when they were more naked, and by participants with more traditional gender roles. There is a need for policy to address potential stigma directed at ‘revenge porn’ victims.  相似文献

The mosquito Anopheles gambiae is the principal Afrotropical vector for human malaria. A central component of its vectorial capacity is the ability to maintain sufficient populations of adults. During both adult and preadult (larval) stages, the mosquitoes depend on the ability to recognize and respond to chemical cues that mediate feeding and survival. In this study, we used a behavioral assay to identify a range of odorant-specific responses of An. gambiae larvae that are dependent on the integrity of the larval antennae. Parallel molecular analyses have identified a subset of the An. gambiae odorant receptors (AgOrs) that are localized to discrete neurons within the larval antennae and facilitate odor-evoked responses in Xenopus oocytes that are consistent with the larval behavioral spectrum. These studies shed light on chemosensory-driven behaviors and represent molecular and cellular characterization of olfactory processes in mosquito larvae. These advances may ultimately enhance the development of vector control strategies, targeting olfactory pathways in larval-stage mosquitoes to reduce the catastrophic effects of malaria and other diseases.  相似文献

In 2008, the New Jersey Department of Health (NJDOH) identified a 21.1% increase in reported invasive pneumococcal disease (IPD). In 2009, NJDOH piloted nucleic acid-based serotyping to characterize serotypes causing IPD. From April through September, NJDOH received specimens from 149 of 302 (49%) case patients meeting our case definition. An uncommon serotype, 10A, accounted for 25.2% of IPD overall and was identified in 12 counties, but it was associated with one county (rate ratio = 5.4, 95% confidence interval [CI] 2.1, 11.8). NJDOH subsequently conducted a case-control study to assess the presentation of and clinical risk factors for 10A IPD. Case patients with 10A IPD were more likely to have had immunosuppression, asthma, and multiple chronic medical conditions than control subjects had (odds ratio [OR] = 2.6, 95% CI 1.1, 6.3; OR=4.7, 95% CI 1.7, 13.2; and OR=2.3, 95% CI 1.0, 5.2, respectively). State-based pneumococcal serotype testing identified an uncommon serotype in New Jersey. Continued pneumococcal serotype surveillance might help the NJDOH identify and respond to future serotype-specific increases.Streptococcus pneumoniae (S. pneumoniae) is a leading cause of bacterial pneumonia, bacteremia, and meningitis. In 2008, the New Jersey Department of Health (NJDOH) observed a 21.1% increase in reported invasive pneumococcal disease (IPD) compared with IPD cases reported in 2007 (95% confidence interval [CI] 8.6, 35.2, 8.33 cases/100,000 population in 2008 vs. 6.88 cases/100,000 population in 2007), including increases in four counties. In response, in 2009, NJDOH began a pilot project to characterize the serotypes causing IPD and to determine if serotypes not included in current vaccines contributed to these increases. When our investigation identified an unusual serotype, 10A, NJDOH conducted a case-control study to assess the presentation of and clinical risk factors for 10A IPD.  相似文献

Objective

To evaluate the impact of opioid controlled substance agreements (CSAs) enrollment on health care utilization.

Patients and Methods

We retrospectively evaluated health care utilization changes among 772 patients receiving long-term opioid therapy for chronic noncancer pain enrolled in a CSA between July 1, 2015, and December 31, 2015. We ascertained patient characteristics and utilization 12 months before and after CSA enrollment. Decreased utilization was defined as a decrease of 1 or more hospitalizations or emergency department visits and 3 or more outpatient primary and specialty care visits. Multivariate modeling assessed demographic characteristics associated with utilization changes.

Results

The 772 patients enrolled in an opioid CSA during the study period had a mean ± SD age of 63.5±14.9 years and were predominantly female, white, and married. The CSA enrollment was associated with decreased outpatient primary care visits (odds ratio [OR], 0.16; 95% CI, 0.14-0.19) and increased diagnostic radiology services (OR, 1.22; 95% CI, 1.02-1.47). After CSA enrollment, patients with greater comorbidity (Charlson Comorbidity Index score >3) were more likely to have reduced hospitalizations (adjusted OR, 2.8; 95% CI, 1.3-6.0; P=.008), reduced outpatient primary care visits (adjusted OR, 2.0; 95% CI, 1.2-3.2; P=.005), and reduced specialty care visits (adjusted OR, 2.0; 95% CI, 1.2-3.3; P=.006).

Conclusion

For patients receiving long-term opioid therapy for chronic noncancer pain, CSA enrollment is associated with reductions in primary care visits and increased radiologic service utilization. Patients with greater comorbidity were more likely to have reductions in hospitalizations, outpatient primary care visits, and outpatient specialty clinic visits after CSA enrollment. The observational nature of the study does not allow the conclusion that CSA implementation is the primary reason for these observed changes.  相似文献

Background and aims

Children with first complex febrile seizure (CFS) are often admitted for observation. The goals of this study were 1) to assess the risk of seizure recurrence during admission, 2) to determine whether early EEG affects acute management.

Design/methods

We retrospectively reviewed a cohort of children 6–60 months of age admitted from a Pediatric Emergency Department for first CFS over a 15 year period. We excluded children admitted for supportive care of their febrile illness. Data extraction included age, gender, seizure features, laboratory and imaging studies, EEG, further seizures during admission, and antiepileptic drugs (AEDs) given.

Results

One hundred eighty three children met inclusion criteria. Seven patients had seizures during the admission (7/183 or 3.8%) Since 38 children were loaded with anti-epileptic medication during their visit, the adjusted rate is 7/145 or 4.8.Increased risk of seizure recurrence during admission was observed in children presenting with multiple seizures (P = 0.005).EEG was performed in 104/183 children (57%) and led to change in management in one patient (1%, 95% C.I. 0.05–6%). Six of the 7 children with seizure had an EEG. The study was normal in 3 and findings in the other 2 did not suggest/predict further seizures during the admission.

Conclusions

Children with first CFSs are at low risk for seizure recurrence during admission. Multiple seizures at presentation are associated with risk of early recurrence and may warrant an admission. EEG had limited effect on acute management and should not be an indication for admission.  相似文献

Simultaneous primary malignancy of the lung and kidney has been rarely recognized during life. Three patients with synchronous primary pulmonary and renal cancer are described. The pulmonary tumors were asymptomatic and were discovered on plain chest roentgenography. The renal tumors, also asymptomatic, were incidentally discovered on CT, performed for staging. Although one patient was treated with interleukin-2 for a presumed solitary pulmonary metastasis from renal carcinoma, in all three patients, both the kidney and lung tumors were eventually removed either concurrently or sequentially. Prior autopsy case series are reviewed. In the elderly, synchronous asymptomatic pulmonary and renal malignancy is not surprising, and it should be approached as a distinct clinical problem. With the use of chest roentgenography for screening high risk populations and CT for staging, simultaneous primary pulmonary and renal malignancy will probably be recognized increasingly.  相似文献
