RESUMO

The primary goal of the peer review of research grant proposals is to evaluate their quality for the funding agency. An important secondary goal is to provide constructive feedback to applicants for their resubmissions. However, little is known about whether review feedback achieves this goal. In this paper, we present a multi-methods analysis of responses from grant applicants regarding their perceptions of the effectiveness and appropriateness of peer review feedback they received from grant submissions. Overall, 56-60% of applicants determined the feedback to be appropriate (fair, well-written, and well-informed), although their judgments were more favorable if their recent application was funded. Importantly, independent of funding success, women found the feedback better written than men, and more white applicants found the feedback to be fair than non-white applicants. Also, perceptions of a variety of biases were specifically reported in respondents' feedback. Less than 40% of applicants found the feedback to be very useful in informing their research and improving grantsmanship and future submissions. Further, negative perceptions of the appropriateness of review feedback were positively correlated with more negative perceptions of feedback usefulness. Importantly, respondents suggested that highly competitive funding pay-lines and poor inter-panel reliability limited the usefulness of review feedback. Overall, these results suggest that more effort is needed to ensure that appropriate and useful feedback is provided to all applicants, bolstering the equity of the review process and likely improving the quality of resubmitted proposals.

RESUMO

BACKGROUND: Clinical data to guide management of patients with cancer and hepatitis B virus (HBV) infection who are treated with immunosuppressive chemotherapy are lacking. The purpose of this study was to describe HBV+ rates in a population of patients with cancer and evaluate a risk-stratified management protocol for the prevention of HBV reactivation (HBVr). METHODS: This was a descriptive study conducted in an integrated healthcare delivery system. Patients with cancer and hepatitis B virus infection who received immunosuppressive chemotherapy between 1 January 2014 and 31 January 2016 were included. A risk-stratified management protocol that continued for six months after chemotherapy completion or 12 months after completion of B-cell targeted chemotherapy was assessed. Outcomes included the proportion of patients who were HBV+ and amongst patients who initiated immunosuppressive therapy, proportions who received hepatitis B virus monitoring or anti-hepatitis B virus prophylaxis, or experienced HBVr or hepatitis B virus-related complications. RESULTS: There were 2463 patients with cancer screened for hepatitis B virus with 114 (4.6%) HBV+ of whom 59 (51.8%) initiated chemotherapy. Included patients were primarily older, male, and white with gastrointestinal or hematologic cancers and initiated intermediate/low-risk cytotoxic chemotherapy. During follow-up, 41 (69.5%) received hepatitis B virus DNA monitoring and 17 (28.8%) initiated anti-hepatitis B virus prophylaxis. No HBVr was observed. ALT and AST abnormalities were common but mostly Grade 1 and primarily related to the patient's malignancy or medications. CONCLUSIONS: Universal hepatitis B virus screening coupled with a risk-stratified management strategy utilizing HBVr monitoring and anti-hepatitis B virus prophylaxis in HBV+ patients receiving immunosuppressive chemotherapy for cancer may prevent HBVr.

RESUMO

Scientific peer reviewers play an integral role in the grant selection process, yet very little has been reported on the levels of participation or the motivations of scientists to take part in peer review. The American Institute of Biological Sciences (AIBS) developed a comprehensive peer review survey that examined the motivations and levels of participation of grant reviewers. The survey was disseminated to 13,091 scientists in AIBS's proprietary database. Of the 874 respondents, 76% indicated they had reviewed grant applications in the last 3 years; however, the number of reviews was unevenly distributed across this sample. Higher review loads were associated with respondents who had submitted more grant proposals over this time period, some of whom were likely to be study section members for large funding agencies. The most prevalent reason to participate in a review was to give back to the scientific community (especially among frequent grant submitters) and the most common reason to decline an invitation to review was lack of time. Interestingly, few suggested that expectation from the funding agency was a motivation to review. Most felt that review participation positively influenced their careers through improving grantsmanship and exposure to new scientific ideas. Of those who reviewed, respondents reported dedicating 2-5% of their total annual work time to grant review and, based on their self-reported maximum review loads, it is estimated they are participating at 56-87% of their capacity, which may have important implications regarding the sustainability of the system. Overall, it is clear that participation in peer review is uneven and in some cases near capacity, and more needs to be done to create new motivations and incentives to increase the future pool of reviewers.

RESUMO

While it is widely recognized that financial stock portfolios can be stabilized through diverse investments, it is also possible that certain habitats can function as natural portfolios that stabilize ecosystem processes. Here we propose and examine the hypothesis that free-flowing river networks act as such portfolios and confer stability through their integration of upstream geological, hydrological, and biological diversity. We compiled a spatially (142 sites) and temporally (1980-present) extensive data set on fisheries, water flows, and temperatures, from sites within one of the largest watersheds in the world that remains without dams on its mainstem, the Fraser River, British Columbia, Canada. We found that larger catchments had more stable fisheries catches, water flows, and water temperatures than smaller catchments. These data provide evidence that free-flowing river networks function as hierarchically nested portfolios with stability as an emergent property. Thus, free-flowing river networks can represent a natural system for buffering variation and extreme events.

RESUMO

Research on fisheries bycatch and discards frequently involves the assessment of reflex impairment, injury, or blood physiology as means of quantifying vitality and predicting post-release mortality, but exceptionally few studies have used all three metrics concurrently. We conducted an experimental purse seine fishery for Pacific salmon in the Juan de Fuca Strait, with a focus on understanding the relationships between different sublethal indicators and whether mortality could be predicted in coho salmon (Oncorhynchus kisutch) bycatch. We monitored mortality using a ~24-h net pen experiment (N = 118) and acoustic telemetry (N = 50), two approaches commonly used to assess bycatch mortality that have rarely been directly compared. Short-term mortality was 21% in the net pen experiment (~24 h) and estimated at 20% for telemetry-tagged fish (~48-96 h). Mortality was predicted by injury and reflex impairment, but only in the net pen experiment. Higher reflex impairment was mirrored by perturbations to plasma ions and lactate, supporting the notion that reflex impairment can be used as a proxy for departure from physiological homeostasis. Reflex impairment also significantly correlated with injury scores, while injury scores were significantly correlated with plasma ion concentrations. The higher time-specific mortality rate in the net pen and the fact that reflexes and injury corresponded with mortality in that experiment, but not in the telemetry-tagged fish released into the wild could be explained partly by confinement stress. While holding experiments offer the potential to provide insights into the underlying causes of mortality, chronic confinement stress can complicate the interpretation of patterns and ultimately affect mortality rates. Collectively, these results help refine our understanding of the different sublethal metrics used to assess bycatch and the mechanisms that can lead to mortality.

RESUMO

BACKGROUND: Vascular endothelial growth factor inhibitors such as bevacizumab, sorafenib, and sunitinib are utilized in the treatment of multiple cancers. Although these agents are associated with hypertension, there is a lack of evidence describing patterns of antihypertensive use in patients with vascular endothelial growth factor inhibitor-associated hypertension in a non-trial, "real-world" setting. OBJECTIVE: To describe the occurrence and severity of vascular endothelial growth factor inhibitor-associated hypertension, patterns of antihypertensive use and occurrence of cardiovascular complications in a non-trial population, and to describe patterns of initial antihypertensive therapy in patients developing hypertension during treatment with a vascular endothelial growth factor inhibitor. METHODS: This retrospective cohort study utilized claims data from the Medstat MarketScan Commercial Claims and Encounter database to identify patients with claims for a vascular endothelial growth factor inhibitor and a diagnosis of cancer using International Classification of Diseases, 9th Revision, Clinical Modification codes, Healthcare Common Procedure Coding System J-codes and National Drug Codes. The study period encompassed claims from one year before the patient's first claim for a vascular endothelial growth factor inhibitor, and continued through one year after the initial vascular endothelial growth factor inhibitor claim. Patients meeting study criteria were classified into cohorts A1, patients with no hypertension throughout the study period; A2, patients without hypertension at baseline who developed hypertension after starting a vascular endothelial growth factor inhibitor; and cohort B, patients with hypertension prior to receiving a vascular endothelial growth factor inhibitor. We utilized medical and pharmacy claims data to describe the presence of hypertension, its severity, and the occurrence of cardiovascular complications throughout the study period. Initial antihypertensive use in cohort A2 was described. RESULTS: In all, 2177 patients met study criteria and were categorized into cohorts A1 (n = 708), A2 (n = 333) and B (n = 1136). Approximately 32% of patients without hypertension at baseline had claims suggestive for hypertension during the study period. Life-threatening (Grade 4) hypertension increased throughout the study period for cohorts A1, A2, and B, to 3.4%, 10.2%, and 16.4%, respectively (p < 0.001 for all). Claims suggestive of Grade 3 hypertension occurred in more patients in cohort B (45.8%) than in cohort A2 (32.7%, p < 0.001). Cardiovascular complications occurred in 4.7%, 15.6%, and 22.7% of patients in cohorts A1, A2, and B, respectively. Initial antihypertensive agent selection did not impact the occurrence of cardiovascular complications in cohort A2. CONCLUSION: Our study provides valuable insight into non-trial patterns of vascular endothelial growth factor inhibitor-associated hypertension occurrence and severity, and is consistent with prior claims analysis. Identification of optimal strategies to manage vascular endothelial growth factor inhibitor-associated hypertension remain to be clarified with the advent of more comprehensive data sets.

RESUMO

OBJECTIVE: To review vismodegib, the first Food and Drug Administration (FDA)-approved Hedgehog (Hh) signaling pathway inhibitor, in the treatment of advanced basal cell carcinoma (BCC). DATA SOURCES: MEDLINE and PubMed were searched using the terms vismodegib, GDC-0449, RG3616, and basal cell carcinoma for relevant clinical trials through September 2013. The FDA Web site, the National Clinical Trials registry, and abstracts from the American Society of Clinical Oncology (ASCO) were also evaluated to identify unpublished data and future clinical trials. STUDY SELECTION/DATA EXTRACTION: All identified clinical and preclinical studies published in the English language were assessed, including selected references from the bibliographies of articles. DATA SYNTHESIS: Activation of the Hh signaling pathway is well documented in BCC. Vismodegib is a small-molecule inhibitor of Hh signaling that acts by antagonizing the protein Smoothened (SMO), thereby preventing downstream transcriptional activation of genes involved in cell proliferation and survival. Vismodegib was approved by the FDA in January 2012 for the treatment of recurrent, locally advanced BCC (laBCC), or metastatic BCC (mBCC) for which surgery or radiation cannot be utilized. A pivotal phase 2 trial evaluating 104 patients demonstrated that treatment with vismodegib, 150 mg orally once daily, resulted in a 30% and 43% objective response rate in patients with mBCC and laBCC, respectively. The most common adverse effects from vismodegib were mild to moderate and included muscle spasms, dysgeusia, decreased weight, fatigue, alopecia, and diarrhea. However, clinical studies noted a high incidence of discontinuation of therapy by patients for reasons other than disease progression. CONCLUSIONS: The approval of vismodegib represents the only targeted, prospectively studied treatment option for patients with advanced BCC. Further research assessing the utility of vismodegib in the treatment of other malignancies and the development of resistance patterns will more clearly define the role of Hedgehog inhibition in the broader scheme of oncological disorders.

RESUMO

OBJECTIVE: To review the characteristics and clinical trial data of crizotinib in ALK-positive non-small cell lung cancer (NSCLC). DATA SOURCE: A literature search using PubMed/MEDLINE (up to December 2012) was performed using the terms crizotinib, ALK-positive, non-small cell lung cancer, and PF-02341066. STUDY SELECTION/DATA EXTRACTION: Phase 1, 2, and 3 trials evaluating the safety and efficacy of crizotinib in a cohort of patients with ALK rearrangements and advanced NSCLC were evaluated. All peer-reviewed articles with clinically relevant information were reviewed. DATA SYNTHESIS: ALK rearrangement results in an aberrant EML4-ALK fusion oncogene that constitutively activates ALK tyrosine kinase, resulting in inhibition of apoptosis and promotion of tumor cell proliferation. Approximately 3-5% of NSCLC exhibit this rearrangement. Crizotinib is an oral selective inhibitor of ALK and mesenchymal epithelial growth factor tyrosine kinases. Early phase trials with crizotinib showed improved response rates of 50-57% and extended duration of response of 6-10 months. Results of these studies led to accelerated Food and Drug Administration (FDA) approval of crizotinib. Further clinical trial results confirmed improvement in response rates, duration of response, as well as progression-free survival in ALK-positive patients with NSCLC receiving crizotinib. The drug undergoes hepatic metabolism by CYP3A4 and demonstrates autoinhibition of CY3A4, thus predisposing it to drug interactions. The most frequent toxicities with crizotinib include mild visual disturbances, nausea, vomiting, diarrhea, constipation, edema, and generally reversible, sometimes severe, elevations in aspartate aminotransferase and alanine aminotransferase. CONCLUSIONS: Crizotinib is a novel targeted anticancer agent that appears to be a favorable treatment option for patients with locally advanced or metastatic NSCLC that is ALK-positive as detected by an FDA-approved test.

RESUMO

Most oral health care providers encounter older adults in their practices and can play a critical role in supporting independence and quality of life for this aging cohort. Physiologic and structural oral cavity changes associated with normal aging may affect the presentation and oral health care of older adults. This article reviews the normative aging of dentition and oral structures and physiologic changes associated with normal aging, including cardiovascular, metabolic, and musculoskeletal changes, and how they may affect oral health. Oral health providers should be aware of normal aging processes when they plan care or schedule procedures for older adults.

RESUMO

BACKGROUND: Team communication and bias in and out of the operating room have been shown to impact patient outcomes. Limited data exist regarding the impact of communication bias during trauma resuscitation and multidisciplinary team performance on patient outcomes. We sought to characterize bias in communication among health care clinicians during trauma resuscitations. METHODS: Participation from multidisciplinary trauma team members (emergency medicine and surgery faculty, residents, nurses, medical students, emergency medical services personnel) was solicited from verified level 1 trauma centers. Comprehensive semistructured interviews were conducted and recorded for analysis; sample size was determined by saturation. Interviews were led by a team of doctorate communications experts. Central themes regarding bias were identified using Leximancer analytic software (Leximancer Pty Ltd., Brisbane, Australia). RESULTS: Interviews with 40 team members (54% female, 82% White) from 5 geographically diverse Level 1 trauma centers were conducted. More than 14,000 words were analyzed. Statements regarding bias were analyzed and revealed a consensus that multiple forms of communication bias are present in the trauma bay. The presence of bias is primarily related to sex but was also influenced by race, experience, and occasionally the leader's age, weight, and height. The most commonly described targets of bias were females and non-White providers unfamiliar to the rest of the trauma team. Most common sources of bias were White male surgeons, female nurses, and nonhospital staff. Participants perceived bias being unconscious but affecting patient care. CONCLUSION: Bias in the trauma bay is a barrier to effective team communication. Identification of common targets and sources of biases may lead to more effective communication and workflow in the trauma bay. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

RESUMO

OBJECTIVE: To present the current clinical evidence on everolimus for use in pancreatic neuroendocrine tumors (pNET). DATA SOURCES: A literature search was performed using PubMed and MEDLINE (1946-March 2012). Search terms were everolimus, RAD001, mTOR inhibitor, and pancreatic neuroendocrine tumors. Abstracts from the American Society of Clinical Oncology 2000-2012 meetings and Food and Drug Administration (FDA) reviews were searched to obtain otherwise unpublished data. The national clinical trials registry was searched for current and future studies of everolimus in pNET. STUDY SELECTION AND DATA EXTRACTION: Clinical studies available in the English language describing the pharmacology, pharmacokinetics, clinical activity, and safety of everolimus in pNET were included. All peer-reviewed, clinically relevant publications were reviewed for inclusion. DATA SYNTHESIS: Everolimus is an oral mammalian target of rapamycin (mTOR) inhibitor approved by the FDA in May 2011 for the treatment of progressive, advanced pNET. Everolimus exerts its effect by inhibiting multiple downstream pathways of mTOR, which decreases cell proliferation, survival, and angiogenesis. Its pNET indication was based on the results of RADIANT-3, a Phase 3 trial demonstrating increased median progression-free survival (11 months) with everolimus 10 mg orally once daily compared to placebo (4.6 months). Everolimus was well tolerated in clinical trials. The most commonly reported adverse events included stomatitis, rash, diarrhea, fatigue, infections, nausea, and decreased appetite. Grade 3/4 events including anemia, thrombocytopenia, pneumonitis, and hyperglycemia occurred in approximately 5% of patients. CONCLUSIONS: Based on review of the available literature, everolimus is a safe and effective treatment option for patients with low- to intermediate-grade, unresectable or metastatic pNET that have progressed on prior therapies. Until results of head-to-head, randomized controlled trials are conducted to compare everolimus to other treatment options, it cannot be said whether everolimus is more efficacious or tolerable than other treatment options.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of romidepsin in refractory cutaneous T-cell lymphoma (CTCL). DATA SOURCES: An English-language literature search of PubMed and MEDLINE (Nov 2011-April 2012) was performed using the terms romidepsin, CTCL, and depsipeptide (FK228). The National Comprehensive Cancer Network guidelines, American Society of Clinical Oncology abstracts, American Society of Hematology abstracts, clinical trial registry, and prescribing information from the manufacturer were reviewed for additional information. STUDY SELECTION AND DATA EXTRACTION: Phase 1 and 2 trials evaluating the efficacy and safety of romidepsin were reviewed with a specific focus on its use in cutaneous T-cell lymphoma. All peer-reviewed articles with clinically relevant information were evaluated for inclusion. DATA SYNTHESIS: In advanced stage CTCL, single or combination chemotherapy regimen responses are variable and lack durability. Romidepsin is a histone deacetylase inhibitor approved for refractory cutaneous T-cell lymphoma. Romidepsin has shown an improvement in duration of response and pruritus over traditional therapy. In 2 independent Phase 2 trials, romidepsin showed an overall response rate of 34% and durable response of 13-15 months in patients with refractory CTCL. The most frequent toxicities of romidepsin include nausea, vomiting, fatigue, or myelosuppression. Clinically insignificant QT interval changes have been observed but did not correlate with a decrease in left ventricular ejection fraction, or elevated laboratory markers of myocardial damage. CONCLUSIONS: Romidepsin is an effective, durable, and well-tolerated single-agent therapy in patients with refractory CTCL and should be considered for formulary addition in this population.

RESUMO

The aim of this article is to highlight the importance of promoting oral health for the geriatric population and implementing change to address their complex oral and systemic health needs. Oral healthcare providers are unequipped to meet the demanding oral health needs of the aging population, resulting in a geriatric oral health crisis that needs immediate attention and action. Despite the advancements in geriatric education over the last two decades, the geriatric curriculum in 2022 is still inadequate, and varies greatly among different US dental schools for both pre- and postdoctoral programs. Predoctoral students are graduating without being sufficiently trained to identify and treat the dental issues of older adults due to lack of a purposely planned curriculum with balanced didactic and clinical exposure. It is critical to have a trained and competent workforce that meets the oral health needs of current and future older adults. To change the present environment, there is a need for curriculum redesign, faculty development, and training. In addition, more research to evaluate pre- and postdoctoral geriatric dentistry curricula, their impact on increasing access to care, and the likelihood of graduating dentists competent to treat functionally dependent and frail older adults is needed. Furthermore, decision-makers in dental education, national dental organizations, and government institutions must support policies that integrate oral health into overall health through robust reimbursement mechanisms, including a dental benefit in Medicare, and recognition of geriatric dentistry as a specialty.

RESUMO

A continuous packed bed reactor for NADH-dependent biocatalysis using enzymes co-immobilized on a simple carbon support was optimized to 100% conversion in a residence time of 30 min. Conversion of pyruvate to lactate was achieved by co-immobilized lactate dehydrogenase and formate dehydrogenase, providing in situ cofactor recycling. Other metrics were also considered as optimization targets, such as low E factors between 2.5-11 and space-time yields of up to 22.9 g L-1 h-1. The long-term stability of the biocatalytic reactor was also demonstrated, with full conversion maintained over more than 30 h of continuous operation.

RESUMO

BACKGROUND: Funding agencies have long used panel discussion in the peer review of research grant proposals as a way to utilize a set of expertise and perspectives in making funding decisions. Little research has examined the quality of panel discussions and how effectively they are facilitated. METHODS: Here, we present a mixed-method analysis of data from a survey of reviewers focused on their perceptions of the quality, effectiveness, and influence of panel discussion from their last peer review experience. RESULTS: Reviewers indicated that panel discussions were viewed favorably in terms of participation, clarifying differing opinions, informing unassigned reviewers, and chair facilitation. However, some reviewers mentioned issues with panel discussions, including an uneven focus, limited participation from unassigned reviewers, and short discussion times. Most reviewers felt the discussions affected the review outcome, helped in choosing the best science, and were generally fair and balanced. However, those who felt the discussion did not affect the outcome were also more likely to evaluate panel communication negatively, and several reviewers mentioned potential sources of bias related to the discussion. While respondents strongly acknowledged the importance of the chair in ensuring appropriate facilitation of the discussion to influence scoring and to limit the influence of potential sources of bias from the discussion on scoring, nearly a third of respondents did not find the chair of their most recent panel to have performed these roles effectively. CONCLUSIONS: It is likely that improving chair training in the management of discussion as well as creating review procedures that are informed by the science of leadership and team communication would improve review processes and proposal review reliability.

RESUMO

We describe the use of carbon as a versatile support for H2-driven redox biocatalysis for NADH-dependent CX bond reductions in batch and flow reactions. In each case, carbon is providing an electronic link between enzymes for H2 oxidation and reduction of the biological cofactor NAD+, as well as a support for a multi-enzyme biocatalysis system. Carbon nanopowders offer high surface areas for enzyme immobilization and good dispersion in aqueous solution for heterogeneous batch reactions. Difficulties in handling multi-wall carbon nanotubes in aqueous solution are overcome by growing them on quartz tubes to form carbon nanotube column reactors, and we show that these facilitate simple translation of H2-driven biocatalysis into flow processes. Using this flow reactor design, high conversions (90%) and total enzyme turnover numbers up to 54,000 could be achieved. Use of an entirely heterogeneous biocatalysis system simplifies recovery and re-use of the enzymes; combined with highly atom-efficient cofactor recycling, this means that high product purity can be achieved. We demonstrate these methods as platform approaches for overcoming challenges with NADH-dependent biocatalysis.

RESUMO

We describe the implementation of a system of immobilised enzymes for H2-driven NADH recycling coupled to a selective biotransformation to enable H2-driven biocatalysis in flow. This approach represents a platform that can be optimised for a wide range of hydrogenation steps and is shown here for enantioselective ketone reduction and reductive amination.

RESUMO

OBJECTIVE: Optimal methods for medical student assessment in surgery remain elusive. Faculty- and housestaff-written evaluations constitute the chief means of student assessment in medical education. However, numerous studies show that this approach has poor specificity and a high degree of subjectivity. We hypothesized that an objective structured clinical examination (OSCE) in the surgery clerkship would provide additional data on student performance that would confirm or augment other measures of assessment. DESIGN: We retrospectively reviewed data from OSCEs, National Board of Medical Examiners shelf examinations, oral presentations, and written evaluations for 51 third-year Harvard Medical School students rotating in surgery at Massachusetts General Hospital from 2014 to 2015. We expressed correlations between numeric variables in Pearson coefficients, stratified differences between rater groups by one-way analysis of variance, and compared percentages with 2-sample t-tests. We examined commentary from both OSCE and clinical written evaluations through textual analysis and summarized these results in percentages. RESULTS: OSCE scores and clinical evaluation scores correlated poorly with each other, as well as with shelf examination scores and oral presentation grades. Textual analysis of clinical evaluation comments revealed a heavy emphasis on motivational factors and praise, whereas OSCE written comments focused on cognitive processes, patient management, and methods to improve performance. CONCLUSIONS: In this single-center study, an OSCE provided clinical skills data that were not captured elsewhere in the surgery clerkship. Textual analysis of faculty evaluations reflected an emphasis on interpersonal skills, rather than appraisal of clinical acumen. These findings suggest complementary roles of faculty evaluations and OSCEs in medical student assessment.
