ABSTRACT

BACKGROUND: Enhanced Recovery After Surgery Society publishes guidelines on perioperative care, but these guidelines should be validated prospectively. OBJECTIVE: To evaluate the association between compliance with Enhanced Recovery After Surgery Gynecologic/Oncology guideline elements and postoperative outcomes in an international cohort. STUDY DESIGN: The study comprised 2101 patients undergoing elective gynecologic/oncology surgery between January 2011 and November 2017 in 10 hospitals across Canada, the United States, and Europe. Patient demographics, surgical/anesthesia details, and Enhanced Recovery After Surgery protocol compliance elements (pre-, intra-, and postoperative phases) were entered into the Enhanced Recovery After Surgery Interactive Audit System. Surgical complexity was stratified according to the Aletti scoring system (low vs medium/high). The following covariates were accounted for in the analysis: age, body mass index, smoking status, presence of diabetes, American Society of Anesthesiologists class, International Federation of Gynecology and Obstetrics stage, preoperative chemotherapy, radiotherapy, operating time, surgical approach (open vs minimally invasive), intraoperative blood loss, hospital, and Enhanced Recovery After Surgery implementation status. The primary end points were primary hospital length of stay and complications. Negative binomial regression was used to model length of stay, and logistic regression to model complications, as a function of compliance score and covariates. RESULTS: Patient demographics included a median age 56 years, 35.5% obese, 15% smokers, and 26.7% American Society of Anesthesiologists Class III-IV. Final diagnosis was malignant in 49% of patients. Laparotomy was used in 75.9% of cases, and the remainder minimally invasive surgery. The majority of cases (86%) were of low complexity (Aletti score ≤3). In patients with ovarian cancer, 69.5% had a medium/high complexity surgery (Aletti score 4-11). Median length of stay was 2 days in the low- and 5 days in the medium/high-complexity group. Every unit increase in Enhanced Recovery After Surgery guideline score was associated with 8% (IRR, 0.92; 95% confidence interval, 0.90-0.95; P<.001) decrease in days in hospital among low-complexity, and 12% (IRR, 0.88; 95% confidence interval, 0.82-0.93; P<.001) decrease among patients with medium/high-complexity scores. For every unit increase in Enhanced Recovery After Surgery guideline score, the odds of total complications were estimated to be 12% lower (P<.05) among low-complexity patients. CONCLUSION: Audit of surgical practices demonstrates that improved compliance with Enhanced Recovery After Surgery Gynecologic/Oncology guidelines is associated with an improvement in clinical outcomes, including length of stay, highlighting the importance of Enhanced Recovery After Surgery implementation.

ABSTRACT

PURPOSE: This study tested the ability of lonidamine (LND), a clinically applicable inhibitor of monocarboxylate transporters (MCT), to thermally sensitise human melanoma cells cultured at a tumour-like extracellular pH (pHe) 6.7. MATERIALS AND METHODS: Human melanoma DB-1 cells cultured at pHe 6.7 and pHe 7.3 were exposed to 150 µM LND for 3 h, beginning 1 h prior to heating at 42 °C (2 h). Intracellular pH (pHi) was determined using 2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein (BCECF) and whole spectrum analysis. Levels of heat shock proteins (HSPs) were determined by immunoblot analysis. Cell survival was determined by colony formation. RESULTS: Treatment with LND at pHe 6.7 reduced pHi to 6.30 ± 0.21, reduced thermal induction of HSPs, and sensitised cells growing at pHe 6.7 to 42 °C. When LND was combined with an acute acidification from pHe 6.7 to pHe 6.5, pHi was reduced to 6.09 ± 0.26, and additional sensitisation was observed. LND had negligible effects on cells cultured at pH 7.3. CONCLUSIONS: The results show that LND can reduce pHi in human melanoma cells cultured at a tumour-like low pHe so that the 42 °C induction of HSPs are abrogated and the cells are sensitised to thermal therapy. Cells cultured at a normal tissue-like pHe 7.3 were not sensitised to 42 °C by LND. These findings support the strategy that human melanoma cells growing in an acidic environment can be sensitised to thermal therapy in vivo by exposure to an MCT inhibitor such as LND.

ABSTRACT

AIMS AND OBJECTIVES: To explore and understand medical-surgical nurses' perceived self-confidence and leadership abilities as first responders in recognising and responding to clinical deterioration prior to the arrival of an emergency response team. BACKGROUND: Patients are admitted to hospitals with multiple, complex health issues who are more likely to experience clinical deterioration. The majority of clinical deterioration events occur on medical-surgical units, and medical-surgical nurses are frequently the first healthcare professionals to identify signs and symptoms of clinical deterioration and initiate life-saving interventions. DESIGN: A prospective, cross-sectional, descriptive quantitative design using a survey method was used. METHODS: Nurses were recruited from an integrated healthcare system located in the south-east United States. Nurses completed a demographic, a self-confidence and a leadership ability questionnaire. RESULTS: One hundred and forty-eight nurses participated in the study. Nurses felt moderately self-confident in recognising, assessing and intervening during clinical deterioration events. In addition, nurses felt moderately comfortable performing leadership skills prior to the arrival of an emergency response team. A significant, positive relationship was found between perceived self-confidence and leadership abilities. Age and certification status were significant predictors of nurses' leadership ability. CONCLUSION: Although nurses felt moderately self-confident and comfortable with executing leadership abilities, improvement is needed to ensure nurses are competent in recognising patients' deterioration cues and making sound decisions in taking appropriate, timely actions to rescue patients. Further strategies need to be developed to increase nurses' self-confidence and execution of leadership abilities in handling deterioration events for positive patient outcomes. RELEVANCE TO CLINICAL PRACTICE: Educational provisions should focus on various clinical deterioration events to build nurses' self-confidence and leadership abilities in handling clinical deterioration. Nurses should obtain national certification to increase their knowledge and clinical reasoning skills.

ABSTRACT

OBJECTIVE: The objective of this study is to examine the outcomes of combined chemotherapy using methotrexate and dactinomycin in the management of women with low-risk gestational trophoblastic neoplasia (GTN). The primary outcome is the total number of cycles of chemotherapy required to achieve a normal level of human chorionic gonadotropin (hCG). The secondary outcome is treatment-related toxicity. METHODS: A retrospective chart review of all patients with GTN treated between 1996-2007 and 1991-2007 was performed at the Alberta Cross Cancer Institute and the British Columbia Cancer Agency, respectively. Patients with low-risk GTN, treated with 0.6 mg/m(2) dactinomycin (days 1 and 2) and methotrexate 100mg/m(2) were included. Toxicities were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events. The number of cycles to achieve normalization of hCG was determined, and multivariate analyses were performed to identify factors associated with treatment duration. RESULTS: One hundred women were eligible. The average age was 29 years (range 15-46). The median number of cycles to achieve a normal hCG was 3 (range 1-11). Two patients required second-line treatment and one patient chose to proceed with hysterectomy. Ninety-eight percent of patients were primarily cured with this regimen, and 2 were cured with second line treatment. Grade 3 and 4 hematologic toxicities were experienced by 12% and 8% of patients, respectively. Grade 2 and 3 stomatitis or mucositis were noted in 44% and 3% of patients, respectively. CONCLUSIONS: Low-risk GTN is reliably and rapidly cured with combined methotrexate-dactinomycin. Toxicity is modest.

ABSTRACT

OBJECTIVES: Preoperative mechanical bowel preparation (MBP) is commonly used in gynecologic oncology (GO). We wished to assess the practice patterns and beliefs within the Society of Gynecologic Oncologists of Canada (GOC), review the literature on MBP as applicable to GO surgeries, and construct recommendations specific to our subspecialty. METHODS: A 23-question, 10-minute Internet survey was sent to 110 GOC members regarding their use, rationale, and understanding of the literature pertaining to MBP for GO surgeries. The historical justifications for using MBP before pelvic and abdominal surgery were identified through literature review. RESULTS: Half of respondents (48%) routinely order MBP despite acknowledgment in 77% that there was no good evidence to support its use. Use encompassed all cancer sites (53% ovary, 32% endometrial, 27% cervical, and 8% vulvar) and approaches (43% laparotomy and 29% laparoscopy/robotics). The most common reasons cited for ordering MBP were to decrease risk of anastomotic leak and improve visualization. In the last 5 years, use of MBP has decreased in most (77%) GOC respondents. Of all respondents, 71% felt that formal recommendations specific to the field of GO would be helpful. None of the arguments for using MBP could be justified in the literature. In contrast, common and often serious sequelae from MBP are frequently described. Admitted use of bowel preparation in other surgical specialties was even higher (53%-99%) than within the GOC. CONCLUSIONS: There is no literature to support the routine use of MBP in GO. Published recommendations (herein) should support and guide change in practice.

ABSTRACT

BACKGROUND: Lower urinary tract dysfunction is a common morbidity related to radical hysterectomy (RAH). Although transurethral catheterization (TUC) has traditionally been used for postoperative bladder drainage following RAH, suprapubic catheterization (SPC) is an alternative method that may be advantageous. OBJECTIVES: To determine, by means of a retrospective cohort study, the incidence of urinary tract infection (UTI), duration of postoperative hospital stay, and time to trial of voiding in women catheterized suprapubically or transurethrally after RAH for early stage cervical cancer. METHODS: Two hundred twelve patients who underwent RAH and staging for stage IA1 + LVS, 1A2, and 1B1 cancer of the cervix in Edmonton between 1996 and 2006 were included in the study. Three gynaecologic oncologists performed the surgeries. Operative, postoperative, and demographic data were extracted from patient records. Patients were catheterized either suprapubically (SPC group) or transurethrally (TUC group) according to the surgeon's discretion. Comparative tests and multivariate regression analysis were used to compare outcome measures between the groups and to adjust for confounding variables. RESULTS: The TUC group had a higher proportion of patients with UTI (27%) than the SPC group (6%) (P < 0.001). The SPC group had a shorter postoperative hospital stay (4.8 vs. 5.7 days; P < 0.001) and an earlier trial of voiding (2.7 vs. 4.4 days; P < 0. 001). Following regression analysis, statistically significant differences remained for UTI and time to initiation of a trial of voiding. CONCLUSION: After RAH for early stage cervical cancer, suprapubic catheterization is associated with a lower rate of UTI and an earlier trial of voiding than transurethral catheterization.

ABSTRACT

OBJECTIVE: Although the SOGC Strategic Directions 2006-2011 includes a commitment to the development of a human resource strategy for obstetrical and gynaecological care, little is known about the career plans of Canadian obstetrics and gynaecology residents. If we are to determine the needs of our profession, we must be aware of the expected practice patterns of future women's health care providers. The primary objective of this study was to evaluate the future career plans of Canadian obstetrics and gynaecology residents. METHODS: The SOGC Junior Member Committee administered two career surveys to Canadian obstetrics and gynaecology residents. The first was directly distributed to all Canadian residents and collected by local representatives of the SOGC Junior Member Committee in November 2002. The second was electronically administered from November 2005 to January 2006. The data collected from the surveys were collated and analyzed using statistical analysis software. RESULTS: The first survey, in 2002, was completed by 236 obstetrics and gynaecology residents (68% response rate) and the second, in 2006, by 246 (65% response rate). In both surveys, respondents were evenly distributed over all five years of residency training and all residency training programs. In 2002, 63 residents (30%) were considering additional postgraduate fellowship training following completion of residency compared with 130 residents (53%) in 2006 (P < 0.001). In both surveys, senior residents (postgraduate years IV and V) were significantly less likely to consider further postgraduate training than residents in their first three years (2002: 17% vs. 38%; 2006: 42% vs. 58%). Of total respondents to the 2002 and 2006 surveys, 87% planned to practice obstetrics upon graduation. The 2006 survey also found that the majority of residents desired to work in call groups of 6 to 10 physicians, work three to five on-call shifts per month, and work a 40- to 60-hour week; 44% of residents planned work as locums after graduation. CONCLUSION: Recognition of the planned practice patterns of our current residents may assist in the development of an appropriate human resource strategy for future obstetrical and gynaecological care in Canada.

ABSTRACT

PURPOSE: Metabolomics is a new, rapidly expanding field dedicated to the global study of metabolites in biological systems. In this article metabolomics is applied to find urinary biomarkers for breast and ovarian cancer. EXPERIMENTAL DESIGN: Urine samples were collected from early- and late-stage breast and ovarian cancer patients during presurgical examinations and randomly from females with no known cancer. After quantitatively measuring a set of metabolites using nuclear magnetic resonance spectroscopy, both univariate and multivariate statistical analyses were employed to determine significant differences. RESULTS: Metabolic phenotypes of breast and ovarian cancers in comparison with normal urine and with each other revealed significance at Bonferroni-corrected significance levels resulting in unique metabolite patterns for breast and ovarian cancer. Intermediates of the tricarboxylic acid cycle and metabolites relating to energy metabolism, amino acids, and gut microbial metabolism were perturbed. CONCLUSIONS: The results presented here illustrate that urinary metabolomics may be useful for detecting early-stage breast and ovarian cancer.

ABSTRACT

OBJECTIVE: To report a case of autoimmune thrombocytopenia due to chronic lymphocytic leukemia (CLL) treated with fludarabine. CASE SUMMARY: A 68-year-old white woman with CLL was treated with oral chlorambucil. She subsequently presented with severe autoimmune thrombocytopenia purpura (ITP). Intravenous gammaglobulin was administered without response, and a therapeutic splenectomy produced only a temporary response, with platelets reaching 65 x 10(3)/mm(3). Four weeks later, the platelet level was below 10 x 10(3)/mm(3). At that time, the woman was treated with fludarabine. The platelet count 4 weeks later was normal (270 x 10(3)/mm(3)) and has been sustained for over 22 months. DISCUSSION: Fludarabine has been reported to be causative in the onset of autoimmune cytopenias with CLL. Our case cautiously suggests fludarabine as a potential treatment for cases of CLL-associated ITP refractory to standard therapy. CONCLUSIONS: Fludarabine could be considered as treatment of ITP in CLL refractory to standard treatment.
