불안방어에 대한 단계적 지침 (Coping with Anxiety: A Stem-by-Step Guide)
Cohn Lucile 대한간호협회 1980 대한간호 Vol.19 No.5
이 글은 Wisconsin주 Milwaukee General Hospital의 정신간호학과 과장으로 있는 Lucile Cohn박사가 자신의 경험에 의해 터득한 불안에 대한 방어기술을 언급한 것으로 임상에 있는 간호원으로 하여금 불안을 제거하고 이를 건설적으로 처리할 수 있게 하는데 지침이 될 수 있다고 생각되어 소개한다.

본 논문의 1부에서는 Graham Greene이 그의 작품 The Quiet American의 주인공 Alden Pyle을, 1950년대 전반과 중반에 걸쳐 월남에서의 실재인물이며 OSS대원인 Edward G. Landsdale을 어느 정도로 모델로 하였는가를 밝혀보고자 하였다. 특히 중요한 것은 Landsdale과 Trinh minh th?장군과의 관계를 둘러싸고 있는 사실들에 관한 규명이니, 왜냐하면 Greene의 Alden Pyle이 소설속의 Th?장군에게 많은 월남 민간인들을 죽게하였던 테러 폭발 사건에 사용된 플라스틱 폭탄들을 제공하였기 때문이다. 2분에서는 Greene의 The Quiet American의 성격묘사 인물들의 상호관계, 분위기와 mood, 철학과 도덕의 문제, 그리고 문체등과 Hemingway의 The Sun Also Rises와의 유사성을 증명하려고 시도하였다.
Cancer genetics for the general Gynecologist
( David E. Cohn ) 대한산부인과학회 2022 대한산부인과학회 학술대회 Vol.108 No.-
As the cancer genome has been mapped, the genetic basis of disease has been progressively elucidated. This has led to a greater understanding of inherited cancer syndromes that result from germline mutations to somatic acquisition of mutations in cancers. Preventative or early detection strategies in people with inherited cancer susceptibility genes has led to a reduction in the death from certain cancers. Somatic cancer analysis has led to improved prognostic and predictive biomarkers as well as novel approaches to cancer therapy that result in improved outcomes. This presentation will review our current understanding of cancer genetics and will identify practical applications of this knowledge for general gynecologists.

Objective: To assess the potential cost-effectiveness of prehabilitation in medically frail patients undergoing surgery for epithelial ovarian cancer (EOC). Methods: We created a cost-effectiveness model evaluating the impact of prehabilitation on a cohort of medically frail women undergoing primary surgical intervention for EOC. Cost was assessed from the healthcare system perspective via (1) inpatient charges from 2018–2019 institutional Diagnostic Related Grouping data for surgeries with and without major complications; (2) nursing facility costs from published market surveys. Major complication and non-home discharge rates were estimated from the literature. Based on published pilot studies, prehabilitation was determined to decrease these rates. Incremental cost-effectiveness ratio for cost per life year saved utilized a willingness-to-pay threshold of $100,000/life year. Modeling was performed with TreeAge software. Results: In a cohort of 4,415 women, prehabilitation would cost $371.1 Million (M)versus $404.9 M for usual care, a cost saving of $33.8 M/year. Cost of care per patient with prehabilitation was $84,053; usual care was $91,713. When analyzed for cost-effectiveness, usual care was dominated by prehabilitation, indicating prehabilitation was associated with both increased effectiveness and decreased cost compared with usual care. Sensitivity analysis showed prehabilitation was more cost effective up to a cost of intervention of $9,418/patient. Conclusion: Prehabilitation appears to be a cost-saving method to decrease healthcare system costs via two improved outcomes: lower complication rates and decreased care facility requirements. It represents a novel strategy to optimize healthcare efficiency. Prospective studies should be performed to better characterize these interventions in medically frail patients with EOC.
Photometric redshift requirements for lens galaxies in galaxy–galaxy lensing analyses

<P><B>ABSTRACT</B></P><P>Weak gravitational lensing is a valuable probe of galaxy formation and cosmology. Here we quantify the effects of using photometric redshifts (photo‐<I>z</I>) in galaxy–galaxy lensing, for both sources and lenses, both for the immediate goal of using galaxies with photo‐<I>z</I> as lenses in the Sloan Digital Sky Survey (SDSS) and as a demonstration of methodology for large, upcoming weak lensing surveys that will by necessity be dominated by lens samples with photo‐<I>z</I>. We calculate the bias in the lensing mass calibration as well as consequences for absolute magnitude (i.e. <I>k</I>‐corrections) and stellar mass estimates for a large sample of SDSS Data Release 8 (DR8) galaxies. The redshifts are obtained with the template‐based photo‐<I>z</I> code <SMALL>zebra</SMALL> on the SDSS DR8 <I>ugriz</I> photometry. We assemble and characterize the calibration samples (∼9000 spectroscopic redshifts from four surveys) to obtain photometric redshift errors and lensing biases corresponding to our full SDSS DR8 lens and source catalogues. Our tests of the calibration sample also highlight the impact of observing conditions in the imaging survey when the spectroscopic calibration covers a small fraction of its footprint; atypical imaging conditions in calibration fields can lead to incorrect conclusions regarding the photo‐<I>z</I> of the full survey.</P><P>For the SDSS DR8 catalogue, we find σ<SUB>Δ<I>z</I>/(1+<I>z</I>)</SUB>= 0.096 and 0.113 for the lens and source catalogues, with flux limits of <I>r</I>= 21 and 21.8, respectively. The photo‐<I>z</I> bias and scatter is a function of photo‐<I>z</I> and template types, which we exploit to apply photo‐<I>z</I> quality cuts. By using photo‐<I>z</I> rather than spectroscopy for lenses, dim blue galaxies and <I>L</I><SUB>*</SUB> galaxies up to <I>z</I>∼ 0.4 can be used as lenses, thus expanding into unexplored areas of parameter space. We also explore the systematic uncertainty in the lensing signal calibration when using source photo‐<I>z</I>, and both lens and source photo‐<I>z</I>; given the size of existing training samples, we can constrain the lensing signal calibration (and therefore the normalization of the surface mass density) to within 2 and 4 per cent, respectively.</P>

Background: This study analyzed questions entered online by rotator cuff patients and determined types and quality of websites providing information at the top of queries. Methods: Three strings related to rotator cuff repair were explored in Google Search. The result pages were manually collected under the “People also ask” function for frequent questions and associated webpages. Questions were categorized using Rothwell’s classification with further topical subcategorization. Webpages were evaluated by Journal of American Medical Association (JAMA) benchmark criteria for source quality. Results: One hundred twenty “People also ask” questions were collected with their associated webpages. Based on the Rothwell classification of questions, queries were thematically organized into fact (41.7%), value (31.7%), and policy (26.7%) categories. The most common webpage categories were academic (28.3%) and medical practice (27.5%). The most common question subcategories were timeline of recovery (21.7%), indications/management (21.7%), and pain (18.3%). The average JAMA score for all 120 webpages was 1.50. Journal articles had the highest average JAMA score (3.77), while commercial websites had the lowest JAMA score (0.91). The most common suggested question for rotator cuff repair/surgery was, “Is rotator cuff surgery worth having?,” while the most common suggested question for rotator cuff repair pain was, “What happens if a rotator cuff is not repaired?” Conclusions: The most common questions asked on Google pertaining to rotator cuff repair evaluate management options and relate to the timeline of recovery and pain management. Most information is provided by medical practice, academic, and medical information websites, which have highly variable reliability. By understanding the questions that rotator cuff repair patients are asking online, surgeons can tailor preoperative education to common patient concerns and improve postoperative outcomes. Level of evidence: IV.
