Parotidectomy for deep lobe pleomorphic adenomas is associated with higher rates of complications and recurrence.

BACKGROUND: Pleomorphic adenoma (PA) is a common parotid tumor, yet due to the relative rarity of deep lobe PA (DLPA), there is a paucity of information about its clinical presentation and surgical outcomes. METHODS: We reviewed the charts of patients with previously untreated parotid PA between the years 1990 and 2015. Clinical parameters and surgical outcomes were compared between superficial lobe PA (SLPA) and DLPA. RESULTS: The cohort comprised 147 cases of DLPA and 222 cases of SLPA. DLPA were larger (median 2.6 cm vs. 2.0 cm, p < 0.001), more often discovered incidentally on imaging (33%, n = 48) and had unique presentations (pharyngeal mass, dysphagia, otalgia). Postsurgical complications were more frequently observed in DLPA (41% vs. 30% in SLPA, p = 0.025), mainly transient facial nerve weakness. DLPA also showed higher recurrence rates (n = 6, 4.1% vs. n = 1, 0.4%, p = 0.016). CONCLUSIONS: Parotidectomy for DLPA carries a higher risk of complications and recurrence compared to SLPA.

Assessing journal author guidelines for systematic reviews and meta-analyses: findings from an institutional sample.

OBJECTIVES: Systematic reviews and meta-analyses (SRs/MAs) are designed to be rigorous research methodologies that synthesize information and inform practice. An increase in their publication runs parallel to quality concerns and a movement toward standards to improve reporting and methodology. With the goal of informing the guidance librarians provide to SR/MA teams, this study assesses online journal author guidelines from an institutional sample to determine whether these author guidelines address SR/MA methodological quality. METHODS: A Web of Science Core Collection (Clarivate) search identified SRs/MAs published in 2014-2019 by authors affiliated with a single institution. The AMSTAR 2 checklist was used to develop an assessment tool of closed questions specific to measures for SR/MA methodological quality in author guidelines, with questions added about author guidelines in general. Multiple reviewers completed the assessment. RESULTS: The author guidelines of 141 journals were evaluated. Less than 20% addressed at least one of the assessed measures specific to SR/MA methodological quality. There was wide variation in author guidelines between journals from the same publisher apart from the American Medical Association, which consistently offered in-depth author guidelines. Normalized Eigenfactor and Article Influence Scores did not indicate author guideline breadth. CONCLUSIONS: Most author guidelines in the institutional sample did not address SR/MA methodological quality. When consulting with teams embarking on SRs/MAs, librarians should not expect author guidelines to provide details about the requirements of the target journals. Librarians should advise teams to follow established SR/MA standards, contact journal staff, and review SRs/MAs previously published in the journal.

Are Financial Payments From the Pharmaceutical Industry Associated With Physician Prescribing? : A Systematic Review.

BACKGROUND: Financial payments from the drug industry to U.S. physicians are common. Payments may influence physicians' clinical decision making and drug prescribing. PURPOSE: To evaluate whether receipt of payments from the drug industry is associated with physician prescribing practices. DATA SOURCES: MEDLINE (Ovid), Embase, the Cochrane Library, Web of Science, and EconLit were searched without language restrictions. The search had no limiting start date and concluded on 16 September 2020. STUDY SELECTION: Studies that estimated the association between receipt of industry payments (exposure) and prescribing (outcome). DATA EXTRACTION: Pairs of reviewers extracted the primary analysis or analyses from each study and evaluated risk of bias (ROB). DATA SYNTHESIS: Thirty-six studies comprising 101 analyses were included. Most studies (n = 30) identified a positive association between payments and prescribing in all analyses; the remainder (n = 6) had a mix of positive and null findings. No study had only null findings. Of 101 individual analyses, 89 identified a positive association. Payments were associated with increased prescribing of the paying company's drug, increased prescribing costs, and increased prescribing of branded drugs. Nine studies assessed and found evidence of a temporal association; 25 assessed and found evidence of a dose-response relationship. LIMITATION: The design was observational, 21 of 36 studies had serious ROB, and publication bias was possible. CONCLUSION: The association between industry payments and physician prescribing was consistent across all studies that have evaluated this association. Findings regarding a temporal association and dose-response suggest a causal relationship. PRIMARY FUNDING SOURCE: National Cancer Institute.

Professional development outcomes associated with interdisciplinary research: An integrative review.

BACKGROUND: Interdisciplinary research among health care professionals has gained importance over the last 20 years, but little is known about its impact on career development. PURPOSE: This study examined professional development outcomes associated with interdisciplinary research. METHODS: An integrative review was conducted using Whittmore and Knafl's framework. PubMed, Embase, PsycInfo, Web of Science, and CINAHL were searched to identify studies. FINDINGS: Thirteen studies were included. The majority used bibliometric analyses, finding that moderate level of interdisciplinary collaboration was associated with a greater amount and higher quality of publications. Interdisciplinary publications allocated more credit (i.e., had more authors). Interdisciplinary research proposals had less funding success than single discipline proposals. Important cultural and personal aspects of interdisciplinary research (e.g., work and communication styles, research goals) have not been assessed to date. DISCUSSION: Rigorous qualitative studies are needed to characterize benefits and challenges of interdisciplinary research to scholars and to institutions.

Systematic Review of Patient-Reported Outcomes following Surgical Treatment of Lymphedema.

INTRODUCTION: Analysis of quality of life (QOL) outcomes is an important aspect of lymphedema treatment since this disease can substantially impact QOL in affected individuals. There are a growing number of studies reporting patient-reported outcomes (PROMs) for patients with lymphedema. The purpose of this study was to conduct a systematic review of outcomes and utilization of PROMs following surgical treatment of lymphedema. METHODS: A literature search of four databases was performed up to and including March, 2019. Studies included reported on QOL outcomes after physiologic procedures, defined as either lymphovenous bypass (LVB) or vascularized lymph node transplant (VLNT), to treat upper and/or lower extremity primary or secondary lymphedema. RESULTS: In total, 850 studies were screened-of which, 32 studies were included in this review. Lymphovenous bypass was the surgical intervention in 16 studies, VLNT in 11 studies, and both in 5 studies. Of the 32 total studies, 16 used validated survey tools. The most commonly used PROM was the lymph quality of life measure for limb lymphedema (LYMQOL) (12 studies). In the remaining four studies, the upper limb lymphedema 27 scale (ULL27), the short form 36 questionnaire (SF-36), the lymphedema functioning, disability and health questionnaire (Lymph-ICF), and lymphedema life impact scale (LLIS) were each used once. QOL improvement following surgical treatment was noted in all studies. CONCLUSIONS: Physiologic surgical treatment of lymphedema results in improved QOL outcomes in most patients. The use of validated PROM tools is increasing but there is no current consensus on use. Future research to evaluate the psychometric properties of PROMs in lymphedema is needed to guide the development and use of lymphedema-specific tools.

How has DSM-5 Affected Autism Diagnosis? A 5-Year Follow-Up Systematic Literature Review and Meta-analysis.

We conducted a 5-year follow-up systematic review and meta-analysis to determine change in frequency of autism spectrum disorder (ASD) diagnosis since diagnostic and statistical manual 5 (DSM-5) publication and explore the impact of Social Communication Disorder (SCD). For 33 included studies, use of DSM-5 criteria suggests decreases in diagnosis for ASD [20.8% (16.0-26.7), p < 0.001], DSM-IV-TR Autistic Disorder [10.1% (6.2-16.0), p < 0.001], and Asperger's [23.3% (12.9-38.5), p = 0.001]; pervasive developmental disorder-not otherwise specified decrease was not significant [46.1% (34.6-58.0), p = 0.52]. Less than one-third [28.8% (13.9-50.5), p = 0.06] of individuals diagnosed with DSM-IV-TR but not DSM-5 ASD would qualify for SCD. Findings suggest smaller decreases in ASD diagnoses compared to earlier reviews. Future research is needed as concerns remain for impaired individuals without a diagnosis.

Clinical applications of breast cancer metabolomics using high-resolution magic angle spinning proton magnetic resonance spectroscopy (HRMAS 1H MRS): systematic scoping review.

INTRODUCTION: Breast cancer is a heterogeneous disease with different prognoses and responses to systemic treatment depending on its molecular characteristics, which makes it imperative to develop new biomarkers for an individualized diagnosis and personalized oncological treatment. Ex vivo high-resolution magic angle spinning proton magnetic resonance spectroscopy (HRMAS 1H MRS) is the most common technique for metabolic quantification in human surgical and biopsy tissue specimens. OBJECTIVE: To perform a review of the current available literature on the clinical applications of HRMAS 1H MRS metabolic analysis in tissue samples of breast cancer patients. METHODS: This systematic scoping review included original research papers published in the English language in peer-reviewed journals. Study selection was performed independently by two reviewers and preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed. RESULTS: The literature search returned 159 studies and 26 papers were included as part of this systematic review. There was considerable variation regarding tissue type, aims, and statistical analysis methods across the different studies. To facilitate the interpretation of the results, the included studies were grouped according to their aims or main outcomes into: feasibility and tumor diagnosis (n = 6); tumor heterogeneity (n = 2); correlation with proteomics/transcriptomics (n = 3); correlation with prognostic factors (n = 11); and response evaluation to NAC (n = 4). CONCLUSION: There is a lot of potential in including metabolic information of breast cancer tissue obtained with HRMAS 1H MRS. To date, studies show that metabolic concentrations quantified by this technique can be related to the diagnosis, prognosis, and treatment response in breast cancer patients.

Genomic profiling in pancreatic ductal adenocarcinoma and a pathway towards therapy individualization: A scoping review.

CONTEXT: Pancreatic cancer (PDAC) is one of the most challenging cancers to treat with modest recent improvements in survival from new systemic therapies. There is growing interest in individualized therapy underpinned by somatic and germline genomic alterations. OBJECTIVE: A systematic review of data on therapies targeting somatic and germline alterations, and their downstream pathways in PDAC. METHOD: A systematic literature search was conducted using PRISMA guidelines to include relevant results published after January 1, 2008. RESULTS: A total of 71 relevant studies were included. We identified 36 studies targeting the KRAS-pathway, the most common being with MEK-inhibitor therapy. Twenty-two studies were identified that evaluated platinum-based chemotherapy and PARP inhibitors in patients with deleterious mutations in DNA damage repair genes and have shown encouraging results. Immunotherapy has demonstrated activity in patients with mismatch repair deficiency/microsatellite instability. CONCLUSION: Evidence from translational and clinical research presents an exciting platform for genomic targeted therapy in PDAC. Validity for targeting BRCA with platinum and PARP inhibitors and microsatellite instability with immune therapy has been established, nonetheless, evidence for targeting the common driver oncogenes is lacking and much work is needed. Of importance is identifying the subgroup of KRAS -wild type PDAC (approximately 5%) where there is enrichment for targetable opportunities.

A Systematic Review of Treatment Options for Grieving Older Adults.

PURPOSE OF REVIEW: a)The purpose of this systematic review was to characterize the studies published on grief interventions for bereaved older adults in the last 5 years. Grief intervention studies were included that exclusively focused on older adults as well as those that included older adults in their samples, in order to summarize the most up-to-date treatment options available for bereaved older adults. RECENT FINDINGS: b)Twenty-four articles that investigated grief interventions in older adults were identified. Generally, findings suggest viable treatment approaches for bereaved older adults are those incorporating behavioral activation and guidance on restoration-oriented coping. However, similar to studies of broader adult populations, grief interventions had small effects on grief-related symptoms in older adults. Few studies examined age as a moderator of treatment effects. Studies varied greatly by study design, sample size, and outcomes measured, which all likely impacted the efficacy of results. SUMMARY: c)This review suggests that, while there has been a growing focus on older adults, who have unique vulnerabilities in bereavement, the evidence-base of efficacious interventions for this population is limited. Given the need for specialized bereavement support for older adults will increase in the coming years, future research should prioritize rigorous investigations of grief treatment options leveraging technology to increase access and incorporate techniques that enhance engagement in life and connectedness for this vulnerable population.
