Forum: Feminism in German Studies

From Professor Wallach\u27s contribution entitled Jews and Gender : To consider Jews and gender within German Studies is to explore the evolution of German‐Jewish Studies with respect to feminist and gender studies. At times this involves looking beyond German Studies to other scholarship in Jewish gender studies, an interdisciplinary subfield in its own right. Over the past few decades, the focus on gender within German‐Jewish Studies has experienced several shifts in line with broader trends: an initial focus on the history of Jewish women and feminist movements gradually expanded to encompass the study of gender identity, masculinity, and sexuality. Historical and literary scholarly approaches now operate alongside and in dialogue with interdisciplinary scholarship in cultural studies, film and visual studies, performance studies, and other fields.

Recurrence and survival outcomes after anatomic segmentectomy versus lobectomy for clinical stage I non- Small-cell lung cancer: a propensity-matched analysis

Purpose: Although anatomic segmentectomy has been considered a compromised procedure by many surgeons, recent retrospective, single-institution series have demonstrated tumor recurrence and patient survival rates that approximate those achieved by lobectomy. The primary objective of this study was to use propensity score matching to compare outcomes after these anatomic resection approaches for stage I non-small-cell lung cancer. Patients and Methods: A retrospective data set including 392 segmentectomy patients and 800 lobectomy patients was used to identify matched segmentectomy and lobectomy cohorts (n = 312 patients per group) using a propensity score matching algorithm that accounted for confounding effects of preoperative patient variables. Primary outcome variables included freedom from recurrence and overall survival. Factors affecting survival were assessed by Cox regression analysis and Kaplan-Meier estimates. Results: Perioperative mortality was 1.2% in the segmentectomy group and 2.5% in the lobectomy group (P = .38). At a mean follow-up of 5.4 years, comparing segmentectomy with lobectomy, no differences were noted in locoregional (5.5% v 5.1%, respectively; P = 1.00), distant (14.8% v 11.6%, respectively; P = .29), or overall recurrence rates (20.2% v 16.7%, respectively; P = .30). Furthermore, when comparing segmentectomy with lobectomy, no significant differences were noted in 5-year freedom from recurrence (70% v 71%, respectively; P = .467) or 5-year survival (54% v 60%, respectively; P = .258). Segmentectomy was not found to be an independent predictor of recurrence (hazard ratio, 1.11; 95% CI, 0.87 to 1.40) or overall survival (hazard ratio, 1.17; 95% CI, 0.89 to 1.52). Conclusion: In this large propensity-matched comparison, lobectomy was associated with modestly increased freedom from recurrence and overall survival, but the differences were not statistically significant. These results will need further validation by prospective, randomized trials (eg, Cancer and Leukemia Group B 140503 trial)

Variation between plant species in pollen digestion rates in the green lacewing Chrysoperla carnea

Pollen are an important food source for numerous insects and may be used as natural markers in ecological studies. However, to make inferences about the movement rates of insects based on their gut contents, information on pollen digestion rates is needed. Here, we assessed how the consumption and digestion rates of pollen ingested by Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) adults are influenced by plant species, temperature, and sex. We offered pollen of two insect-pollinated plants – Acer pseudoplatanus L. (Sapindaceae) and Helianthus annuus L. (Asteraceae) – and two wind-pollinated plants – Fraxinus excelsior L. (Oleaceae) and Quercus rubra L. (Fagaceae) – differing in size and protein content, to adult lacewings at two temperatures, 20 and 25 °C. After feeding, lacewings were allowed to digest pollen for up to 14 days, sampled at 10 time intervals. At each of these intervals, lacewings were frozen and the internal pollen were obtained through acetolysis and quantified under a light microscope. The number of pollen grains decreased exponentially over time and declined faster for Acer than for the other three plant species. The half-life and the time at which 95% of the pollen grains were digested were lower for Acer than for the other plant species. Lacewings consumed more pollen grains from Acer and Quercus than from Fraxinus and Helianthus. Male lacewings consumed 30% fewer pollen grains than females, but without differences in their digestion rates. Our results show that lacewings consumed higher amounts of high-protein pollen (Acer and Quercus) and that digestion rates differed among plant species, which could be linked to their structural characteristics. The variable digestion rates of pollen grains may influence the study of lacewing diet composition. Studies that make inferences about the pollen diet or movement ecology of lacewings by analysing their gut contents should account for species-specific pollen digestion rates

Intraoperative Cytology for Video-Assisted Thoracic Surgery : A Quality Improvement Analysis

Background: Frozen section is a standard of care procedure during thoracic surgery when an immediate diagnosis is needed. An alternative procedure is intraoperative cytology. Video-assisted thoracic surgery is currently widely used for thoracic surgical procedures. The aim of this study was to assess intraoperative cytology together with frozen section for accuracy, turnaround time, and total response time during video-assisted thoracic surgery. Methods: We included patients having video-assisted thoracic surgery between August 2018 and February 2019 at our institution. A cytopathologist and a surgical pathologist independently performed intraoperative cytology and frozen sections, respectively. Final histologic diagnosis was the reference standard. Intraoperative cytology, frozen section turnaround, and total response times were analyzed. Results: A total of 52 specimens from 27 patients were included. The intraoperative cytology correlated with final histology in 98% of cases. Frozen section correlated with final histology in 100% of cases. Intraoperative cytology turnaround and total response times were equal (mean, 4.35 minutes; range, 2-15 minutes). Mean frozen section turnaround and response times were 26.2 minutes (range, 9-61 minutes) and 36.7 minutes (range, 16-90 minutes), respectively. We found a statistically significant difference between intraoperative cytology and frozen section turnaround time and total response times (P < .001). Conclusions: This study highlights that intraoperative cytology could be as accurate as frozen section and considerably faster during video-assisted thoracic surgery (P < .001). Total response time could potentially be used as a quality metric for video-assisted thoracic surgery
