Phentermine: A Systematic Review for Plastic and Reconstructive Surgeons.

PURPOSE: Phentermine is the most prescribed antiobesity drug in America, with 2.43 million prescriptions written in 2011. Case reports suggest there are anesthetic risks, such as refractory hypotension, involved with its perioperative use. Despite these risks and the frequency of phentermine use among plastic surgery patients, there are no published guidelines for the perioperative management of phentermine use in the plastic surgery literature. To address this patient safety issue, we performed a systematic review and provide management recommendations. METHODS: A systematic review of the pharmacology of phentermine and the anesthetic risks involved with its perioperative use was undertaken using the search engines PubMed/MEDLINE, EMBASE, and Scopus. RESULTS: A total of 251 citations were reviewed, yielding 4 articles that discussed perioperative phentermine use and complications with anesthesia. One was a review article, 2 were case reports, and 1 was a letter. Complications included hypotension, hypertension, hypoglycemia, hyperthermia, bradycardia, cardiac depression, and acute pulmonary edema. CONCLUSIONS: The relationship between phentermine and anesthesia, if any, is unclear. Hypotension on induction of general anesthesia is the most reported complication of perioperative phentermine use. Specifically, phentermine-induced hypotension may be unresponsive to vasopressors that rely on catecholamine release, such as ephedrine. Therefore, the decision to perform surgery, especially elective surgery, in a patient taking phentermine should be made with caution. Because of the half-life of phentermine, we recommend discontinuing phentermine for at least 4 days prior to surgery. This differs from the classic 2-week discontinuation period recommended for "fen-phen." The patient should be made aware of the increased risk of surgery, and a skilled anesthesiologist should monitor intraoperative blood pressure and body temperature for signs of autonomic derailment.

The impact of limited English proficiency on oncological outcomes in the United States: A systematic review.

BACKGROUND: The increasing number of immigrants in the United States (U.S.) has resulted in more patients with limited English proficiency (LEP). LEP contributes to patient-provider language discordance, which may impact oncologic health outcomes. OBJECTIVES: To assess the effects of LEP compared to English proficiency (EP) for oncological outcomes in adult cancer patients in the United States. SEARCH METHODS: We searched MEDLINE (Ovid), the Cochrane Library (Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials), PsycINFO, CINAHL and Scopus from data inception to 26 January 2023. We also searched the reference lists and cited lists of included studies. Studies were limited to the United States and the English language. SELECTION CRITERIA: We included retrospective and cross-sectional studies that analyzed one or more clinical outcomes (survival, readmission, length of stay, complications and discharge disposition) in LEP and EP cancer patients. Studies were eligible if they assessed cancer patients in the United States who were 18 years and older. DATA COLLECTION AND ANALYSIS: Using a piloted, standardized data collection form, two non-blinded, independent reviewers extracted data in duplicate from studies meeting our inclusion criteria. Reviewers resolved discrepancies through discussion. We then performed a qualitative assessment of the findings. MAIN RESULTS: We retrieved 2425 records from the database searches. We screened 1496 records by title and abstract and reviewed the full text of eight records. We retrieved 347 records from additional search methods and reviewed the full text of six records. We included 14 papers in total for analysis. The studies included 55,141 total patients and assessed outcomes in brain, oesophageal, head and neck, pancreatic and skin cancer. Our qualitative assessment demonstrated limited information on whether LEP impacted survival, complications and discharge disposition. We found no significant association between LEP and readmission or length of stay. CONCLUSIONS: Studies assessing the impact of LEP and EP on the health outcomes of cancer patients are sparse and inconsistent in the measurements of outcomes and data reporting. The inconclusiveness of our study indicates that further standardized research is needed to assess the impact of LEP on the outcomes of cancer patients in the United States.

Comprehensive Literature Search to Identify Assessment Tools for Operating Room Nontechnical Skills to Determine Common Critical Components.

BACKGROUND: Effective use of nontechnical skills (NTS) contributes to the provision of safe, quality care in the fast-paced, dynamic setting of the operating room (OR). Inter-professional education of NTS to OR team members can improve performance. Such training requires the accurate measurement of NTS in order to identify gaps in their utilization by OR teams. Although several instruments for measuring OR NTS exist in the literature, each tool tends to define specific NTS differently. AIM: We aimed to determine commonalities in defined measurements among existing OR NTS tools. METHODS: We undertook a comprehensive literature review of assessment tools for OR NTS to determine the critical components common to these instruments. A PubMed search of the literature from May 2009 to May 2019 combined various combinations of keywords and Medical Subject Headings (MeSH) related to the following subjects: teamwork, teams, assessment, debriefing, surgery, operating room, nontechnical, communication. From this start, articles were selected describing specific instruments. Three reviewers then identified the common components measured among these assessment tools. Reviewers collated kin constructs within each instrument using frequency counts of similarly termed and conceptualized components. RESULTS: The initial PubMed search produced 119 articles of which 24 articles satisfied the inclusion criteria. Within these articles, 10 assessment tools evaluated OR NTS. Kin constructs were grouped into six NTS categories in the following decreasing frequency order: communication, situation awareness, teamwork, leadership, decision making, and task management/decision making (equal). CONCLUSION: NTS OR assessment tools in the literature have a variety of kin constructs related to the specific measured components within the instruments. Such kin constructs contain thematic cohesion across six primary NTS groupings with some variation in scale and scope. Future plans include using this information to develop an easy-to-use assessment tool to assist with debriefing in the clinical environment.

Primary Resection and Immediate Autologous Reconstruction of Fronto-orbital Infantile Myofibromatoses.

Infantile myofibromatosis is an unusual and rare lesion of the bone and soft tissue, which can be seen in the craniofacial skeleton. These complex tumors present a challenge to craniofacial surgeons regarding diagnosis, management, and safe and effective surgical treatment, frequently requiring complex reconstruction. We present the case of a 7-month-old girl with multicentric infantile myofibromatosis of the right parietal and fronto-orbital region, the associated clinical presentation, histopathologic findings, and surgical management, along with a review of the relevant literature.

Improvement in student-led debriefing analysis after simulation-based team training using a revised teamwork assessment tool.

BACKGROUND: Team debriefing is an important teamwork development intervention for improving team outputs in healthcare. Debriefing is a key component of experiential team training teamwork development interventions such as simulation-based training. Improving the quality of debriefing of healthcare teams, therefore, has multiple benefits. We investigated whether the quality of student-led debriefing improved using a shortened guide. METHODS: Senior medical students, nurse anesthesia students, and senior undergraduate nursing students participated in student operating room team training at a health sciences center in the southeastern United States. Student teams participated in a dual-scenario simulation-based training session with immediate after-action debriefings after each scenario. In 2018, student teams conducted the second debriefing using as a guide the teamwork assessment scale, an 11-item, 3-subscale, 6-point Likert-type instrument. In 2019, they used a shortened, revised, 5-item version of the teamwork assessment scale, the quick teamwork assessment scale. Trained observers rated the quality of the student-led debriefings using the Objective Structured Assessment of Debriefing, an 8-item, 5-point instrument. The Wilcoxon-Mann-Whitney test was used to compare the teamwork assessment scale-guided and the quick teamwork assessment scale-guided mean item debriefing scores. RESULTS: Two observers rated 3 student-led team debriefings using the teamwork assessment scales as a guide in 2018, and 6 such debriefings happened using the quick teamwork assessment scale as a guide in 2019. For each debriefing, observer scores were averaged for each Objective Structured Assessment of Debriefing item; these mean scores were then averaged with other mean scores for each year. The use of the quick teamwork assessment scale resulted in a statistically significant higher mean score for the Analysis Objective Structured Assessment of Debriefing item compared with the use of the teamwork assessment scale (4.92 [standard deviation 0.20] versus 3.83 [standard deviation 0.76], P = .023). CONCLUSION: The use of a shortened teamwork assessment instrument as a debriefing guide for student teams in student operating room team training was more effective in analysis of actions than the original, longer tool. Next steps include determining the efficacy of the quick teamwork assessment scale in an actual clinical setting.

Predictors of Inappropriate Helicopter Transport.

BACKGROUND: Helicopter transport (HT) is an efficient, but costly, means for injured patients to receive life-saving, definitive trauma care. Identifying the characteristics of inappropriate HT presents an opportunity to improve the utilization of this finite medical resource. METHODS: Trauma registry records of all HT for a 3-year period (2016-2018) to an urban Level I trauma center were reviewed. HT was defined as inappropriate for patients who were discharged home from the emergency department or had a hospital length of stay <1 day, and who were discharged alive. Chi-square analysis and Student's t-test were used for univariate analysis. Predictors with a P value of less than .15 were subject to binary logistic regression analysis. A P value ≤.05 was considered significant. RESULTS: There were 713 patients who received HT during the study period. One-hundred and forty-eight (20.8%) patients met the criteria as an inappropriate HT. In univariate analysis, Glasgow Coma Scale >8, Shock Index <0.9, and fall mechanism were found to be significantly associated with inappropriate HT. Age >55 was found to be associated with an appropriate HT. The average Injury Severity Score of the inappropriate HT group was 3.86 (±3.85) compared with 16.80 (±11.23) (P = .0001, Student's t-test). DISCUSSION: Our findings suggest that there are evidence-based predictors of patients receiving inappropriate HT. Triage of HT using these predictors has the potential to decrease unnecessary deployments and reduce health care costs.

A Microphysiologic Platform for Human Fat: Sandwiched White Adipose Tissue.

White adipose tissue (WAT) plays a crucial role in regulating weight and everyday health. Still, there are significant limitations to available primary culture models, all of which have failed to faithfully recapitulate the adipose microenvironment or extend WAT viability beyond two weeks. The lack of a reliable primary culture model severely impedes research in WAT metabolism and drug development. To this end we have utilized NIH's standards of a microphysiologic system to develop a novel platform for WAT primary culture called 'SWAT' (sandwiched white adipose tissue). We overcome the natural buoyancy of adipocytes by sandwiching minced WAT clusters between sheets of adipose-derived stromal cells. In this construct, WAT samples are viable over eight weeks in culture. SWAT maintains the intact ECM, cell-to-cell contacts, and physical pressures of in vivo WAT conditions; additionally, SWAT maintains a robust transcriptional profile, sensitivity to exogenous chemical signaling, and whole tissue function. SWAT represents a simple, reproducible, and effective method of primary adipose culture. Potentially, it is a broadly applicable platform for research in WAT physiology, pathophysiology, metabolism, and pharmaceutical development.

Sandwiched White Adipose Tissue: A Microphysiological System of Primary Human Adipose Tissue.

White adipose tissue (WAT) is a critical organ in both health and disease. However, physiologically faithful tissue culture models of primary human WAT remain limited, at best. In this study we describe a novel WAT culture system in which primary human WAT is sandwiched between tissue-engineered sheets of adipose-derived stromal cells. This construct, called "sandwiched white adipose tissue" (SWAT), can be defined as a microphysiological system (MPS) since it is a tissue-engineered, multicellular, three-dimensional organ construct produced using human cells. We validated SWAT against the National Institutes of Health MPS standards and found that SWAT is viable in culture for 8 weeks, retains physiologic responses to exogenous signaling, secretes adipokines, and engrafts into animal models. These attributes position SWAT as a powerful tool for the study of WAT physiology, pathophysiology, personalized medicine, and pharmaceutical development.
