RESUMO

BACKGROUND: It remains unclear why female general surgery residents perform fewer cases than male peers. This exploratory study investigated possible contributors to gender-based disparities and solutions for improving equity in operative experience. METHODS: Surveys, including Likert scale and free-text questions, were distributed to 21 accredited general surgery residency programs. RESULTS: There were 96 respondents, of whom 69% were female. 22% of females personally experienced barriers to operative experience versus 13% of males (p â€‹= â€‹0.41), while 52% of female residents believed operative training was affected by gender (p â€‹= â€‹0.004). Inductive analysis revealed the most common barrier to operating room participation was floor work/clinical tasks. The most common barrier for female residents was perceived sexism/gender bias, with subthemes of "misidentification," "feeling unwelcome," and "poor trust/autonomy." To improve parity, residents proposed structured program-level review, feedback, and transparent expectations about case assignments. CONCLUSION: Female general surgery residents believe gender bias impacts training. Further mixed-methods research is crucial to determine the cause of gender-based disparities in operative experience.

RESUMO

INTRODUCTION: Increasing interest in general surgery from students who are Under-Represented in Medicine (URiM) is imperative to advancing diversity, equity, and inclusion efforts. We examined medical student third year surgery clerkship evaluations quantitatively and qualitatively to understand the experiences of URiM and non-URiM learners at our institution. METHODS: Evaluations from 235 graduated medical students between the years of 2019 and 2021 were analyzed. T-tests were used to compare numerical data. Free-text comments were qualitatively analyzed using inductive thematic analysis by two independent reviewers with conflicts resolved by a third. RESULTS: Evaluations were completed by 214 non-URiM students (91.1 â€‹%) and 21 (8.9 â€‹%) URiM students. There were no significant differences between URiM and non-URiM students in ratings of faculty and resident teaching. When asked whether residents were positive role models for patient care, non-URiM students were more likely than URiM students to agree (3.284 vs. 2.864, p â€‹= â€‹0.040). When asked whether they considered faculty to be positive role models, non- URM students were also more likely to answer affirmatively than URiM students (3.394 vs. 2.909 p â€‹= â€‹0.013). Qualitative comments were similar between the two groups. When asked what the strengths of the clerkship were, the most commonly evoked theme was "interactions with team" with subthemes of "team integration" "feeling valued" and positive "faculty" or "resident" interactions. "Operative experience" was the second most commonly evoked strength of the clerkship. The most common criticisms of the clerkship involved "negative interactions with team" with subthemes of "not prioritized above other learners" and "ignored." Negative "academic experience" was the next most commonly evoked weakness, with an affiliated theme of "lack of teaching." CONCLUSIONS: URiM students are less likely than non-URiM students to see surgical residents and faculty as positive role models. Integrating medical students into the team, taking time to teach, and allowing students to feel valued in their roles improves the clerkship experience for trainees and can contribute to recruitment efforts.

RESUMO

BACKGROUND: Energy-based devices, such as nonablative lasers, are a promising method to enhance the delivery and absorption of topically applied molecules. OBJECTIVE: To characterize ex vivo uptake of common antioxidant topicals after pretreatment with a nonablative laser wavelength. MATERIALS AND METHODS: Using donor human skin tissue, uptake of 3 topical antioxidants was analyzed (C E Ferulic with 15% l-ascorbic acid [15% vitamin C serum], Phloretin CF with ferulic acid [10% vitamin C serum], and Phyto+ [botanical serum]; SkinCeuticals, Dallas, TX; 2010 formulations) after pretreatment with a 1,440-nm nonablative fractional diode laser. RESULTS: Pretreatment with the 1,440-nm laser enhanced uptake of 15% and 10% vitamin C serums by approximately 10 and 21 times, respectively, compared to controls. Laser pretreatment also enhanced uptake of botanical serum by approximately 6 times relative to controls. Permeation of vitamin C and botanical serums was also enhanced through laser pretreatment. CONCLUSION: Nonablative laser pretreatment increased uptake and permeation of topical antioxidants. Optimizing treatment requires consideration of the device and treatment parameters as well as the properties of the topical formulation.

RESUMO

BACKGROUND: Laser pretreatment with cosmeceutical topicals is growing in popularity. However, lasers may also enhance the uptake of medical topicals that treat dermatologic conditions, such as vitiligo, alopecia, and cancerous and precancerous lesions. Permeation of these topicals must be quantified to optimize treatment protocols. OBJECTIVE: To analyze transdermal uptake of 3 topicals after nonablative fractional 1,550-nm erbium-doped glass or 1,927-nm thulium fiber laser pretreatment. METHODS AND MATERIALS: Human donor tissue was pretreated with a nonablative fractional 1,550-nm erbium-doped glass or 1,927-nm thulium fiber laser followed by application of 0.03% bimatoprost, 0.5% 5-fluorouracil, or 5% minoxidil. Permeation and retention were measured over 24 hours (bimatoprost and 5-fluorouracil) or 90 minutes (minoxidil), and uptake was calculated. RESULTS: Pretreatment with 1,927-nm thulium laser (500 MTZ/cm2; 5 mJ; 5 W) enhanced uptake and retention of bimatoprost versus untreated control at 24 hours post-treatment. Pretreatment with 1,550-nm erbium-doped glass laser (2,000 MTZ/cm2; 10 mJ; 30 W) enhanced permeation, uptake, and retention of 5-fluorouracil at 24 hours post-treatment and enhanced permeation and uptake of minoxidil at 90 minutes post-treatment. CONCLUSION: Nonablative laser pretreatment may enhance topical treatment of dermatologic conditions. Device settings must be optimized to maximize topical permeation while minimizing laser-associated thermal side effects.

RESUMO

Background: For appropriately selected patients with early-stage breast cancer (ESBC), accelerated partial breast irradiation (APBI) yields equivalent rates of ipsilateral breast tumor recurrence with mixed results in patient-rated cosmesis compared with whole-breast radiotherapy depending on the technique utilized. When utilizing external beam radiotherapy for APBI, techniques to reduce target margins and overall treatment volume are potentially important to decrease rates of long-term adverse cosmesis. Stereotactic body radiotherapy (SBRT) is a promising technique to deliver APBI because of its increased accuracy and sparing of uninvolved breast tissue. We report the initial results of a prospective clinical trial investigating feasibility, safety, and cosmetic outcomes of a daily five-fraction SBRT regimen for APBI. Methods: Twenty-three patients with ESBC after lumpectomy who met APBI suitability were enrolled. During lumpectomy, a bioabsorbable three-dimensional fixed array tissue marker (BioZorb™, Hologic, Marlborough, MA) was placed for enhanced visualization of the cavity boundaries. Clinical target volume (CTV) was defined as the delineable cavity plus a 1-cm isotropic expansion followed by a 3-mm isotropic planning target volume (PTV) expansion. Patients received 30 Gy delivered in five planned consecutive daily fractions in either prone or supine positioning depending on individual anatomy. Two patients completed the five-fraction treatments in 9-day interval and 11-day interval due to external circumstances. A maximum PTV of 124cc was allowed to minimize incidence of fat necrosis. Plans utilized 10-MV flattening filter-free beams delivered on a Varian Edge linear accelerator. Local control, toxicity, and nurse/patient-scored cosmesis at pre-treatment baseline, 1 month post-treatment, and at subsequent 6-month intervals were recorded. Results: Twenty-three patients were accrued at the time of submission with median follow-up of 6 months. No patients experienced grade ≥3 acute toxicity. Of the 10 events reported probably related to SBRT, nine were grade 1 (n = 9/10, 90%). There was no evidence of difference, deterioration, or change in patient or nurse-scored cosmesis from baseline to 1 and 6 months post-treatment. One patient developed nodal failure shortly after APBI. Conclusions: Although longer follow-up is needed to assess long-term toxicity and local control, this study demonstrated a five-fraction SBRT regimen delivered over consecutive days is a safe, efficient, well-tolerated, and cosmetically favorable means of delivering APBI in suitable women.

RESUMO

BACKGROUND: Although the stratum corneum limits transdermal absorption of topicals, laser devices can enhance topical uptake by disrupting the skin barrier. Nonablative lasers are commonly used, but their effects on topical uptake should be quantified to optimize outcomes. OBJECTIVE: The objective of this study is to analyze transdermal uptake of 4 topicals after nonablative fractional diode laser pretreatment. METHODS AND MATERIALS: Human donor tissue was pretreated ex vivo with a nonablative fractional diode laser (1,927 nm or 1,440 nm, at varying treatment densities, powers, and peak energies) followed by application of either 2% salicylic acid, 10% ascorbic acid, over-the-counter mineral eye serum, or 4% hydroquinone. Topical uptake was quantified over 24 hours. RESULTS: Despite lower power settings, pretreatment with the 1,927 nm wavelength was associated with greater uptake of 10% ascorbic acid, mineral eye serum, and 4% hydroquinone than the 1,440 nm wavelength. In addition, 1,440-nm laser pretreatment with higher density (320 microscopic treatment zones [MTZ]/cm 2 ) and peak power (3 W) was associated with similar uptake but greater retention of 2% salicylic acid and greater uptake of 10% ascorbic acid than that with lower density (80 MTZ/cm 2 ) and peak power (1.2 W). CONCLUSION: When using laser pretreatment, device settings should be adjusted to balance outcomes with potential side effects.

RESUMO

BACKGROUND: A number of retrospective and prospective studies have documented substantial rates of regression in cervical intraepithelial neoplasia grade 2 lesions in young women. Initial observational management of cervical intraepithelial neoplasia grade 2 is increasingly accepted as appropriate for women under 25 years of age with screen-detected abnormalities and is included in a number of clinical guidelines. However, there has been a paucity of large prospective studies on observational management with strict inclusion criteria. A number of important questions remain, specifically regarding the clinical variables that are associated with the risk of progression or persistence of disease. To investigate these factors and to ensure that young women with cervical intraepithelial neoplasia grade 2 undergoing observational management were being managed in a well-monitored and an appropriately informed fashion, we conducted a large, multicenter prospective study on observational management of cervical intraepithelial neoplasia grade 2 in women under 25 years. OBJECTIVE: This study aimed to determine the regression rates and clinical, cytologic, and pathologic predictors of regression of cervical intraepithelial neoplasia grade 2 in women under 25 years undergoing observational management over 24 months. STUDY DESIGN: This study was a multicenter prospective study on observational management of cervical intraepithelial neoplasia grade 2 (ie, repeat colposcopy, cytology, and cervical biopsy every 6 months) for up to 24 months. A total of 615 consenting women under 25 years with newly-diagnosed, biopsy-proven cervical intraepithelial neoplasia grade 2 were recruited (from 2010 to 2016) through 16 hospital-based colposcopy units in New Zealand and Australia. RESULTS: At completion, 326 women had confirmed regression, 156 had persistent high-grade cervical intraepithelial neoplasia grade 2 or 3 or adenocarcinoma in situ, and 24 had unconfirmed regression (ie, first regression at the 24-month follow-up). A total of 109 women did not complete the protocol (41 because of delayed follow-up, 41 lost to follow-up, 22 elected treatment, 4 refused a biopsy, and 1 died of an unrelated cause). Confirmed regression was observed in 53% (326 of 615) of all women enrolled in the study and, when missing data were imputed, it was estimated that 64% of women (95% confidence interval, 60%-68%) would have experienced regression. Similarly, lesions regressed in 64% (326 of 506) of women who completed the observational protocol. Based on a multivariable analysis, detection of human papillomavirus 16 in a liquid-based cytology sample at the time of initial colposcopy decreased the chance of regression by 31% (risk ratio, 0.69; 95% confidence interval, 0.56-0.86; P<.001). In addition, at initial colposcopy, low-grade or normal colposcopic impression, later year of diagnosis, low-grade or normal cytology, and being a nonsmoker were all independently associated with an increased chance of regression. CONCLUSION: More than half of women under 25 years with cervical intraepithelial neoplasia grade 2 will regress to cervical intraepithelial neoplasia grade 1 or normal within 24 months without destructive treatment. The absence of human papillomavirus 16 is the most important predictor of regression.

RESUMO

INTRODUCTION: Coronavirus Disease 2019 (COVID-19) is a pandemic infection caused by the Severe Acute Respiratory Syndrome 2 Coronavirus (SARS-2-CoV). Although most prominently associated with pulmonary manifestations, COVID-19 is increasingly implicated in neuropsychiatric complications, including delirium and psychosis. There is a potential causal link between COVID-19 infection and psychotic symptoms; however, case reports to date have been incomplete, as the patients described had known psychiatric histories or other plausible medical causes for altered mental status. We present a longitudinal case of COVID-19 psychosis in a patient who underwent comprehensive diagnostic evaluation. This case is a contribution to the inchoate characterization of neuropsychiatric manifestations of COVID-19 infection. CASE REPORT: We present a case of late-onset psychosis in a middle-aged man with no psychiatric history who tested positive for COVID-19 on admission following a recently resolved upper respiratory illness. His acute presentation-characterized by delusions, hallucinations, and disorganized thought and behavior, for which he required inpatient medical admission and subsequent inpatient psychiatric hospitalization-was successfully treated. During his hospitalization, he underwent comprehensive medical and neurological workup (including neuroimaging; electroencephalography; and serum and cerebrospinal fluid testing) that was grossly unremarkable. DISCUSSION: Despite myriad potential causes of the patient's psychosis, this patient's diagnostic workup was largely unrevealing, apart from his nasopharyngeal SARS-2-CoV reverse transcriptase polymerase chain reaction assay. As such, psychosis secondary to COVID-19 infection emerged as the presumptive diagnosis.

RESUMO

BACKGROUND: Available retrospective data suggest the upgrade rate for intraductal papilloma (IP) without atypia on core biopsy (CB) ranges from 0 to 12%, leading to variation in recommendations. We conducted a prospective multi-institutional trial (TBCRC 034) to determine the upgrade rate to invasive cancer (IC) or ductal carcinoma in situ (DCIS) at excision for asymptomatic IP without atypia on CB. METHODS: Prospectively identified patients with a CB diagnosis of IP who had consented to excision were included. Discordant cases, including BI-RADS > 4, and those with additional lesions requiring excision were excluded. The primary endpoint was upgrade to IC or DCIS by local pathology review with a predefined rule that an upgrade rate of ≤ 3% would not warrant routine excision. Sample size and confidence intervals were based on exact binomial calculations. Secondary endpoints included diagnostic concordance for IP between local and central pathology review and upgrade rates by central pathology review. RESULTS: The trial included116 patients (median age 56 years, range 24-82) and the most common imaging abnormality was a mass (n = 91, 78%). Per local review, 2 (1.7%) cases were upgraded to DCIS. In both of these cases central pathology review did not confirm DCIS on excision. Additionally, central pathology review confirmed IP without atypia in core biopsies of 85/116 cases (73%), and both locally upgraded cases were among them. CONCLUSION: In this prospective study of 116 IPs without atypia on CB, the upgrade rate was 1.7% by local review, suggesting that routine excision is not indicated for IP without atypia on CB with concordant imaging findings.

RESUMO

BACKGROUND: The epidemiology of psychiatric symptoms among patients with coronavirus disease 2019 is poorly characterized. OBJECTIVE: This article sought to identify the prevalence of anxiety, depression, and acute stress disorder among hospitalized patients with coronavirus disease 2019. METHODS: Adult patients recently admitted to nonintensive care unit medical ward settings with coronavirus disease 2019 were eligible for enrollment. Enrolled patients were screened for depression, anxiety, and delirium. Subsequently, patients were followed up by phone after 2 weeks and rescreened for depression, anxiety, and acute stress disorder symptoms. Subjects' medical records were abstracted for clinical data. RESULTS: A total of 58 subjects were enrolled; of whom, 44 completed the study. Initially, 36% of subjects had elevated anxiety symptoms and 29% had elevated depression symptoms. At 2-week follow-up, 9% had elevated anxiety symptoms, 20% had elevated depression symptoms, and 25% had mild-to-moderate acute stress disorder symptoms. Discharge to home was not associated with improvement in psychiatric symptoms. CONCLUSIONS: A significant number of patients hospitalized with coronavirus disease 2019 experienced symptoms of depression and anxiety. While anxiety improved after index admission, depression remained fairly stable. Furthermore, a significant minority of patients experienced acute stress disorder symptoms, though these were largely mild to moderate.

RESUMO

BACKGROUND: The University of Alabama at Birmingham Preventative Care Program for Women's Cancer provides genetic testing, risk evaluation, and screening for breast cancer. Women diagnosed with high-risk mutations may opt to undergo active surveillance or prophylactic surgery. This decision requires understanding of the surveillance process and its potential outcomes. In this study, we report specifically on women with non-BRCA1 or BRCA2 mutations. METHODS: A retrospective, cross-sectional study was conducted of women enrolled in our program identified as high risk because of non-BRCA mutations. Events regarding genetic mutations, method of detection of suspicious lesions, number of biopsies, results of those biopsies, prophylactic surgery, and cancer diagnosis were collected. RESULTS: We identified 78 patients with asymptomatic non-BRCA deleterious mutations. Sixteen mutations were identified, with the most common being ATM, CHEK2, and PALB2. In total, 11.5% underwent prophylactic surgery and 88.5% underwent active surveillance. In the surveillance group, 63.8% had no examination or imaging to warrant biopsy, 24.6% had biopsy with benign result, and 11.6% had biopsy with malignant result. For the nine women who developed breast cancer during surveillance, six were diagnosed with ductal carcinoma in situ, two with stage I, and one with stage IIA cancer. CONCLUSIONS: Women with non-BRCA mutations enroll in prevention clinics with hopes of early detection of breast cancer. Because of increased screening, this population undergoes biopsy more frequently; however, during surveillance most do not require a biopsy. For those that do, the result is typically benign. This information can further allow women to make informed decisions about surveillance and establish realistic expectations regarding the likelihood of tissue sampling.

RESUMO

BACKGROUND: Nausea is one of the most commonly reported side effects in patients receiving chemotherapy. Patients who experience nausea during chemotherapy may also experience depression, metabolic imbalances, dehydration, decreased ability to function, and treatment delays, which can ultimately affect outcomes. OBJECTIVES: This study aimed to determine the efficacy of a cool damp washcloth with peppermint essential oil versus a cool damp washcloth alone on the self-reported intensity of nausea in patients receiving chemotherapy in the outpatient ambulatory setting. METHODS: 79 adult patients receiving chemotherapy were recruited from an outpatient ambulatory infusion center in the southeastern United States. Patients were separated into two groups (no scent and peppermint) and asked to rate the intensity of their chemotherapy-induced nausea at pre- and postintervention using the Baxter Retching Faces pictorial scale. FINDINGS: The results demonstrated that the use of peppermint oil was effective in decreasing the intensity of nausea experienced by patients compared to a cool washcloth alone.

RESUMO

Importance: Approximately 25% of patients with early-stage breast cancer who receive (neo)adjuvant chemotherapy experience a recurrence within 5 years. Improvements in therapy are greatly needed. Objective: To determine if pembrolizumab plus neoadjuvant chemotherapy (NACT) in early-stage breast cancer is likely to be successful in a 300-patient, confirmatory randomized phase 3 neoadjuvant clinical trial. Design, Setting, and Participants: The I-SPY2 study is an ongoing open-label, multicenter, adaptively randomized phase 2 platform trial for high-risk, stage II/III breast cancer, evaluating multiple investigational arms in parallel. Standard NACT serves as the common control arm; investigational agent(s) are added to this backbone. Patients with ERBB2 (formerly HER2)-negative breast cancer were eligible for randomization to pembrolizumab between November 2015 and November 2016. Interventions: Participants were randomized to receive taxane- and anthracycline-based NACT with or without pembrolizumab, followed by definitive surgery. Main Outcomes and Measures: The primary end point was pathologic complete response (pCR). Secondary end points were residual cancer burden (RCB) and 3-year event-free and distant recurrence-free survival. Investigational arms graduated when demonstrating an 85% predictive probability of success in a hypothetical confirmatory phase 3 trial. Results: Of the 250 women included in the final analysis, 181 were randomized to the standard NACT control group (median [range] age, 47 [24.77] years). Sixty-nine women (median [range] age, 50 [27-71] years) were randomized to 4 cycles of pembrolizumab in combination with weekly paclitaxel followed by AC; 40 hormone receptor (HR)-positive and 29 triple-negative. Pembrolizumab graduated in all 3 biomarker signatures studied. Final estimated pCR rates, evaluated in March 2017, were 44% vs 17%, 30% vs 13%, and 60% vs 22% for pembrolizumab vs control in the ERBB2-negative, HR-positive/ERBB2-negative, and triple-negative cohorts, respectively. Pembrolizumab shifted the RCB distribution to a lower disease burden for each cohort evaluated. Adverse events included immune-related endocrinopathies, notably thyroid abnormalities (13.0%) and adrenal insufficiency (8.7%). Achieving a pCR appeared predictive of long-term outcome, where patients with pCR following pembrolizumab plus chemotherapy had high event-free survival rates (93% at 3 years with 2.8 years' median follow-up). Conclusions and Relevance: When added to standard neoadjuvant chemotherapy, pembrolizumab more than doubled the estimated pCR rates for both HR-positive/ERBB2-negative and triple-negative breast cancer, indicating that checkpoint blockade in women with early-stage, high-risk, ERBB2-negative breast cancer is highly likely to succeed in a phase 3 trial. Pembrolizumab was the first of 10 agents to graduate in the HR-positive/ERBB2-negative signature. Trial Registration: ClinicalTrials.gov Identifier: NCT01042379.

RESUMO

BACKGROUND: Right-sizing instrument trays reduce processing and replacement costs, physical strain, and turnover times. Historically, a 98-instrument head and neck tray has been used for breast lumpectomy cases at our institution. Observations revealed that many instruments on the tray were not used during the breast cases. With the significant number of surgical breast lumpectomies performed annually, tray downsizing could significantly reduce costs and physical strain. METHODS: Surgical technicians identified instruments needed for a standard breast lumpectomy. Breast surgeons reviewed the list and made final recommendations. Three of 13 existing head and neck trays were converted to breast lumpectomy trays. The number of breast lumpectomies in 2017 was pulled from the institution's health information system. Instrument quantities were verified using instrument management software. Weights were taken on a digital scale, and processing cost was estimated by a consultant. RESULTS: The new breast trays included 51 instruments rather than the standard 98-instrument trays. Reprocessing cost decreased from $49.98 to $26.01. With 449 breast lumpectomies performed at the institution in 2017, the annual reprocessing savings totaled $10,763. The tray weight was reduced from 27 to 16 pounds. Setup time decreased from 7 to 4 min per use (22.5 h saved annually). CONCLUSIONS: Downsizing from a head and neck tray to a specific breast lumpectomy tray demonstrated a reduction in reprocessing cost, tray weight, and setup time. Lighter trays allow for safer handling and transport by surgical personnel. In the current health-care environment, it is important to maximize operating room efficiency and minimize cost.

RESUMO

BACKGROUND: Mastectomy remains an effective treatment for ductal carcinoma in situ (DCIS) but whether further therapy is warranted for close or positive margins is controversial. We aim to characterize the treatment practices of DCIS throughout the United States in patients who undergo mastectomy with close or positive margins to better understand the use of postmastectomy radiation therapy (PMRT). MATERIALS AND METHODS: Using the 2004-2013 National Cancer Database, we identified all female patients with a diagnosis of DCIS who underwent mastectomy. Distributional characteristics were summarized for overall and margin-stratified samples. Characteristic differences were assessed by region and receipt of radiation. Chi-square and independent sample t-tests were used to assess differences for categorical and continuous variables, respectively. RESULTS: In 21,591 patients who met inclusion criteria, 470 patients with close/positive margins were identified. Sixteen percent of patients with close/positive margins received PMRT compared to 1.5% with negative margins (P < 0.01). There was no difference in PMRT and patient race, insurance status, treatment facility, or endocrine therapy. Patients with close/positive margins who received PMRT were more likely to be in an urban setting from the Midwest (24.6%) and Northeast (21.8%) compared to the West (11.0%) and South (10.7%) (P < 0.01). CONCLUSIONS: Use of PMRT for DCIS following mastectomy with close/positive margins differs across the country. Regional variations in treatment patterns reinforce a need to determine whether PMRT improves survival to establish treatment guidelines.

RESUMO

Over the past several years, there have been numerous changes in the guidelines for screening mammography. Additionally, different societies have released guidelines with variance in the recommendations of age to initiate and frequency of imaging. The current recommendations as well as the importance of screening mammography for early detection and survival are discussed.
