    Practicing Collective Biography

    Get PDF
    Collective biography uses researchers\u27 written memories about a set of experiences as texts for collective analysis. As a feminist approach to research, collective biography draws centrally on the idea that significant memories are critical in the constitution of the self, and maintains that in analyzing memories collectively, researchers can begin to tap into wider social processes and structures. Though rarely used in geography, collective biography could be useful in data collection and analysis for geographers. In this paper, we provide a brief history and description of collective biography. We situate collective biography in relation to life writing methods. We then identify a set of attributes that mark collective biography as a distinct research approach. In closing, we reflect on our experiences working with collective biography

    Background and ObjectivesPrimary colonic lymphoma (PCL) is rare, heterogeneous, and presents a therapeutic challenge for surgeons. Optimal treatment strategies are difficult to standardize, leading to variation in therapy. Our objective was to describe the patient characteristics, short‐term outcomes, and five‐year survival of patients undergoing nonpalliative surgery for PCL.MethodsWe performed a retrospective cohort analysis in the National Cancer Database. Included patients underwent surgery for PCL between 2004 to 2014. Patients with metastases and palliative operations were excluded. Univariate predictors of overall survival were analyzed using multivariable Cox proportional hazard analysis.ResultsWe identified 2153 patients. Median patient age was 68. Diffuse large B‐cell lymphoma accounted for 57% of tumors. 30‐ and 90‐Day mortality were high (5.6% and 11.1%, respectively). Thirty‐nine percent of patients received adjuvant chemotherapy. For patients surviving 90 days, 5‐year survival was 71.8%. Chemotherapy improved survival (surgery+chemo, 75.4% vs surgery, 68.6%; P = .01). Adjuvant chemotherapy was associated with overall survival after controlling for age, comorbidity, and lymphoma subtype (HR 1.27; 95% CI, 1.07‐1.51; P = .01).ConclusionsPatients undergoing surgery for PCL have high rates of margin positivity and high short‐term mortality. Chemotherapy improves survival, but <50% receive it. These data suggest the opportunity for improvement of care in patients with PCL.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/150597/1/jso25582_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/150597/2/jso25582.pd

    How Low Can We Go?: Comparing Long-term Oncologic Outcomes for APR and LAR in Very Low Rectal Cancer

    Management of very low rectal cancer is one of the most challenging issues faced by colorectal surgeons. For tumors in the mid and upper rectum, procedures can be done to resect the cancer while maintaining continence, a major determinant of post-operative quality of life. In the low rectum, however, to optimize oncologic outcomes, many surgeons feel compelled to pursue abdominoperineal (APR) over low anterior resection (LAR), a sphincter-preserving procedure. It was hypothesized that after robust adjustment, procedure choice will not be associated with a difference in disease-free survival in the resection of tumors in the low rectum. To analyze this, the US Rectal Cancer Collaborative Database, a comprehensive, multi-center dataset obtained from six institutions between 2010 and 2016, was queried. Patients undergoing TME resection for Stage I-III very low rectal cancers (involvement) were selected for this study. Patients were categorized by procedure- LAR vs APR. Primary outcome was five-year disease-free survival. Secondary outcomes included overall survival, recurrence, length of stay, and complications. An adjusted analysis was performed to account for all known potential confounders. 431 patients with very low rectal cancer treated by either APR or LAR were identified. 154 (35.7%) underwent APR. The overall recurrence rate was 19.6%. Median follow-up time was 42.5 months. An analysis adjusted for age, gender, BMI, ASA class, and pathologic stage observed no difference in disease free survival between operative types (HR=0.90, 95% CI [0.53-1.52], p=0.70). Similarly, secondary outcomes demonstrated no significant difference between operation types, including length of stay (Beta: 0.04, Std. error = 0.25, p = 0.54), overall survival (HR=1.29, 95% CI [0.71-2.32], p=0.39), or complications (OR = 1.53, 95% CI [0.94 - 2.50], p=0.09). In this analysis, no significant difference in disease-free survival or overall survival was observed between patients undergoing APR or LAR for very low rectal cancer. This comprehensive study supports the treatment of very low rectal cancer, less than 5cm from the anorectal ring with no sphincter involvement, by either abdominal perineal or low anterior resection. Further studies may focus on patient-reported and quality of life outcomes which may influence decision-making

    An eHealth System Supporting Palliative Care for Patients with Non-Small Cell Lung Cancer: A Randomized Trial

    BACKGROUND: In this study, the authors examined the effectiveness of an online support system (Comprehensive Health Enhancement Support System [CHESS]) versus the Internet in relieving physical symptom distress in patients with non-small cell lung cancer (NSCLC). METHODS: In total, 285 informal caregiver-patient dyads were assigned randomly to receive, for up to 25 months, standard care plus training on and access to either use of the Internet and a list of Internet sites about lung cancer (the Internet arm) or CHESS (the CHESS arm). Caregivers agreed to use CHESS or the Internet and to complete bimonthly surveys; for patients, these tasks were optional. The primary endpoint-patient symptom distress-was measured by caregiver reports using a modified Edmonton Symptom Assessment Scale. RESULTS: Caregivers in the CHESS arm consistently reported lower patient physical symptom distress than caregivers in the Internet arm. Significant differences were observed at 4 months (P = .031; Cohen d = .42) and at 6 months (P = .004; d = .61). Similar but marginally significant effects were observed at 2 months (P = .051; d = .39) and at 8 months (P = .061; d = .43). Exploratory analyses indicated that survival curves did not differ significantly between the arms (log-rank P = .172), although a survival difference in an exploratory subgroup analysis suggested an avenue for further study. CONCLUSIONS: The current results indicated that an online support system may reduce patient symptom distress. The effect on survival bears further investigation

    The main purpose of this study was to measure the postcompetition blood lactate concentration ([La]b) in master swimmers of both sexes aged between 40 and 79 years in order to relate it to age and swimming performance. One hundred and eight swimmers participating in the World Master Championships were assessed for [La]b and the average rate of lactate accumulation (La’;mmol l-1 s-1) was calculated. In addition, 77 of them were also tested for anthropometric measures. When the subjects were divided into 10-year age groups, males exhibited higher [La]b than women (factorial ANOVA, P < 0.01) and a steeper decline with ageing than female subjects. Overall, mean values (SD) of [La]b were 10.8 (2.8), 10.3 (2.0), 10.3 (1.9), 8.9 (3.2) mmol l-1 in women, and 14.2 (2.5), 12.4 (2.5), 11.0 (1.6), 8.2 (2.0) mmol l-1 in men for, respectively, 40–49, 50–59, 60–69, 70–79 years’ age groups. When, however, [La]b values were normalised for a ‘‘speed index’’, which takes into account swimming speed as a percentage of world record, these sex-related differences, although still present, were considerably attenuated. Furthermore, the differences in La’ between males and females were larger in the 40–49 age group (0.34 vs 0.20 mmol l-1 s-1 for 50-m distance) than in the 70–79 age group (0.12 vs 0.14 mmol l-1 s-1 for 50-m distance). Different physiological factors, supported by the considered anthropometric measurements, are suggested to explain the results

    Clinical development of new drug-radiotherapy combinations.

    In countries with the best cancer outcomes, approximately 60% of patients receive radiotherapy as part of their treatment, which is one of the most cost-effective cancer treatments. Notably, around 40% of cancer cures include the use of radiotherapy, either as a single modality or combined with other treatments. Radiotherapy can provide enormous benefit to patients with cancer. In the past decade, significant technical advances, such as image-guided radiotherapy, intensity-modulated radiotherapy, stereotactic radiotherapy, and proton therapy enable higher doses of radiotherapy to be delivered to the tumour with significantly lower doses to normal surrounding tissues. However, apart from the combination of traditional cytotoxic chemotherapy with radiotherapy, little progress has been made in identifying and defining optimal targeted therapy and radiotherapy combinations to improve the efficacy of cancer treatment. The National Cancer Research Institute Clinical and Translational Radiotherapy Research Working Group (CTRad) formed a Joint Working Group with representatives from academia, industry, patient groups and regulatory bodies to address this lack of progress and to publish recommendations for future clinical research. Herein, we highlight the Working Group's consensus recommendations to increase the number of novel drugs being successfully registered in combination with radiotherapy to improve clinical outcomes for patients with cancer.National Institute for Health ResearchThis is the final version of the article.
