RESUMEN

Purpose: Two-photon microscopy (2PM) is an emerging clinical imaging modality with the potential to non-invasively assess tissue metabolism and morphology in high-resolution. This study aimed to assess the translational potential of 2PM for improved detection of high-grade cervical precancerous lesions. Experimental Design: 2P images attributed to reduced nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) and oxidized flavoproteins (FP) were acquired from the full epithelial thickness of freshly excised human cervical tissue biopsies (N = 62). Fifteen biopsies harbored high-grade squamous intraepithelial lesions (HSILs), 14 biopsies harbored low-grade SILs (LSILs), and 33 biopsies were benign. Quadratic discriminant analysis (QDA) leveraged morphological and metabolic functional metrics extracted from these images to predict the presence of HSILs. We performed gene set enrichment analysis (GSEA) using datasets available on the Gene Expression Omnibus (GEO) to validate the presence of metabolic reprogramming in HSILs. Results: Integrating metabolic and morphological 2P-derived metrics from finely sampled, full-thickness epithelia achieved a high 90.8 ± 6.1% sensitivity and 72.3 ± 11.3% specificity of HSIL detection. Notably, sensitivity (91.4 ± 12.0%) and specificity (77.5 ± 12.6%) were maintained when utilizing metrics from only two images at 12- and 72-µm from the tissue surface. Upregulation of glycolysis, fatty acid metabolism, and oxidative phosphorylation in HSIL tissues validated the metabolic reprogramming captured by 2P biomarkers. Conclusion: Label-free 2P images from as few as two epithelial depths enable rapid and robust HSIL detection through the quantitative characterization of metabolic and morphological reprogramming, underscoring the potential of this tool for clinical evaluation of cervical precancers.

RESUMEN

STUDY OBJECTIVE: To describe opioid distribution and patient use after gynecologic procedures. DESIGN: Survey study (Canadian Task Force classification III). SETTING: An urban academic tertiary care hospital. SUBJECTS: Ninety-six gynecologists in the Boston area, and 147 patients who underwent a benign hysterectomy between January 2015 and April 2016. INTERVENTIONS: Survey study of physicians and patients composed of 2 parts: (1) a physician survey on opioid prescribing practices after gynecologic procedures and (2) a patient survey on opioid consumption after hysterectomy. Physicians were contacted via e-mail to participate in an online survey. Eligible patients were contacted via telephone and asked to participate in a telephone survey. MEASUREMENTS AND MAIN RESULTS: Fifty-one physicians responded to an online survey and prescribed a mean of 27.1 tablets (range, 5-30) of oxycodone (5 mg) or hydromorphone (2 mg) after abdominal hysterectomy (AH), a mean of 22.6 tablets (range, 5-30) after laparoscopic hysterectomy (LH), and a mean of 16.8 tablets (range 5-30) after vaginal hysterectomy (VH). Physicians prescribed more opioids for AH compared with LH, with a mean difference of 4.5 tablets (standard deviation, 4.7; p < .01), and AH compared with VH, with a mean difference of 6.8 tablets (standard deviation, 5.8; p < .01), which were both statistically significant. In addition, 40.0% of physicians prescribe opioids after a hysteroscopy and 19.2% after a dilation and curettage. Fifty-six patients participated in the telephone survey: 64.6% of patients used less than half of the opioids prescribed and 16.1% used none. For AH, patients reported being prescribed a mean of 25.7 tablets and using a mean of 8.7 tablets (range, 0-60; 33.9% used). For LH or VH, patients reported being prescribed a mean of 24.2 tablets and using a mean of 10.0 tablets (range, 0-30; 41.4% used). Opioid consumption was not significantly different for AH compared with LH or VH (p = .613 for AH to LH, p = .279 for AH to VH). CONCLUSIONS: With respect to the physician survey, we conclude there is a wide range of opioid prescription practices and patient opioid consumption after gynecologic surgery. The patient survey revealed that physicians prescribe fewer opioid tablets after a minimally invasive approach to hysterectomy versus open hysterectomy. However, most patients use less than half of prescribed opioids, and a fraction did not use any opioids at all.

RESUMEN

CONTEXT: - See, Test & Treat is a pathologist-driven program to provide cervical and breast cancer screening to underserved and underinsured patient populations. This program is largely funded by the CAP Foundation (College of American Pathologists, Northfield, Illinois) and is a collaborative effort among several medical specialties united to address gaps in the current health care system. OBJECTIVE: - To provide an outline for administering a See, Test & Treat program, using an academic medical center as a model for providing care and collating the results of 5 years of data on the See, Test & Treat program's findings. DESIGN: - Sources include data from patients seen at Tufts Medical Center (Boston, Massachusetts) who presented to the See, Test & Treat program and institutional data between 2010 and 2014 detailing the outline of how to organize and operationalize a volunteer cancer-screening program. RESULTS: - During the 5-year course of the program, 203 women were provided free cervical and breast cancer screening. Of the 169 patients who obtained Papanicolaou screening, 36 (21.3%) had abnormal Papanicolaou tests. In addition, 16 of 130 patients (12.3%) who underwent mammography had abnormal findings. CONCLUSIONS: - In general, women from ethnic populations have barriers that prevent them from participating in cancer screening. However, the CAP Foundation's See, Test & Treat program is designed to reduce those barriers for these women by providing care that addresses cultural, financial, and practical issues. Although screening programs are helpful in identifying those who need further treatment, obtaining further treatment for these patients continues to be a challenge.

RESUMEN

In 2002, the World Health Organization estimated that over 58% of cardiovascular disease in North America is due to 'both blood pressure and cholesterol higher than optimal'. Unfortunately, less than a third of patients with both conditions are identified, and fewer than one in ten reach the treatment goals for both factors. Adherence to treatment is notably improved when therapy is initiated simultaneously. Combination therapy of amlodipine besylate (Norvasc, Pfizer Ltd) with atorvastatin calcium (Lipitor, Pfizer Ltd), marketed as Caduet (Pfizer Ltd) is the first dual-therapy compound designed to treat hypertension and/or angina and dyslipidemia concurrently with a single daily pill in the full range of dosing combinations. Amlodipine/atorvastatin retains the safety and efficacy of its parent compounds whilst simplifying the management of these comorbid conditions, in what may be considered the first version of a polypill.
