卵巣子宮内膜症性嚢胞の嚢胞液鉄濃度が不妊に及ぼす影響について
The causes of infertility in women with endometriosis may range from anatomical distortions to various pathophysiological disturbances. The aim of the present study was to examine the effects of the cyst fluid (CF) concentration of iron on infertility in patients with ovarian endometrioma (OMA). Patients with histologically confirmed OMA were enrolled at the Department of Obstetrics and Gynecology, Nara Medical University Hospital between 2013 and 2019. The patients were divided into 2 groups, namely women experiencing current infertility (infertile group) and those without complaints of infertility (non‑infertile group). There were 2 types of patients in the infertile group: Patients who failed to achieve a clinical pregnancy following ≥12 months of regular unprotected sexual intercourse and those who had already been treated at fertility clinics. The CF concentration of iron was measured by the inductively coupled plasma‑optical emission spectrometry (ICP‑OES) method. The clinical data were analyzed retrospectively. A total of 77 patients were enrolled in the present study. Among these, 32 (41.6%) patients had infertility. When compared with the non‑infertile women, the infertile women were significantly younger (median age, 35 years; range, 24‑47 years; vs. median age, 40 years; range, 21‑53 years; respectively; P=0.003). The CF concentrations of iron (median, 324.8 mg/l; range, 71.3‑1046.3 mg/l; vs. median, 226.5 mg/l; range, 65.3‑737.5 mg/l; respectively; P=0.019) were significantly higher in the infertile group compared with the non‑infertile group. Multivariate logistic regression analysis indicated that age at diagnosis (≤38 years), the CF concentrations of iron (>326.6 mg/l) and the infertility index (iron/age ratio, >8.37) were independent risk factors for endometriosis‑related infertility. Multivariate analysis revealed that age (HR, 6.44; 95% CI, 2.06‑20.12) and iron (HR, 4.90; 95% CI, 1.48‑16.22) were independent factors for the identification of patients with OMA who presented with a complaint of infertility. In addition, the infertility index (iron/age ratio, >8.37; HR, 4.85; 95% CI, 1.01‑23.27) was an important predictor of infertility. ROC curve analysis also revealed that the areas under the ROC (AUC) for age, iron and infertility index were 0.699, 0.666 and 0.731, respectively. On the whole, the findings of the present study demonstrate that age at diagnosis and the CF concentration of iron may be potentially effective markers for predicting infertility in women with OMA.博士(医学)・乙第1500号・令和3年3月15日Copyright © Nagayasuet al.

授業と実習を通した看護学生のコミュニケーション能力の縦断的変化とその背景要因
看護学生のコミュニケーション能力の縦断的変化について明らかにし、学習支援や授業改善の資料とするために、大学1年生から2年生にわたり縦断的に調査を行った。調査内容及び方法は、コミュニケーション技術評価尺度を、1年生で行うコミュニケーション授業の前後と基礎看護学実習Ⅰ終了後、加えて2年生時の基礎看護学実習Ⅱの終了後に測定した。毎回の授業後には理解度・関心度を調査し、授業終了後には授業評価を実施した。なお、1年生で行う基礎看護学実習Ⅰ終了後には、コミュニケーションに関する感想や学び、課題を自由記述で求めた。結果として、1年生ではコミュニケーションの基本技術が向上し、2年生では、対象との関係性に向かうため非言語コミュニケーション力が向上していた。学習支援上の課題は、グループ活動による学習では、学生の対人緊張を和らげる工夫が必要と考えられた
精神疾患を有する人への「リカバリーゼミ」の実践~参加者の語りからの評価~
精神疾患を有し精神科デイケアや就労支援などの社会資源につながっていない人へのリカバリー支援としてのプログラム「リカバリーゼミ」を実施した。本研究の目的は、本実践が参加者のリカバリー推進に寄与できたのかを考察することである。研究対象者は5 名で、いずれもひきこもり傾向や何らかの依存傾向があった。実施期間は2015 年5 月~ 2016 年6 月で、基本的に月2 回、1 回2 時間のクローズドグループで実施した。結果はRecovery Assessment Scale:RAS の点数が、参加者5 人中4 名終了時に上昇していた。また、生活も参加者の望む方向へ変化していた。このことより「グループ学習や体験を通して参加者が自身の人生を前向きに捉え、自身の責任において自身の希望や目的に向かって、人生の歩みを進める一助となること」という本プログラムの目的を概ね達成し、各人のリカバリー推進に寄与できたと考える
Factors Associated with Cancer-Related Pain Requiring High-Dose Opioid Use in Palliative Cancer Patients
Background:There are no universal tools to predict the necessity of high-dose opioid use for cancer-related pain. Early recognition and interventions for intractable cancer pain could minimize the distress of palliative patients.Objective:We sought to identify the clinical factors associated with high-dose opioid use in advanced cancer patients to recognize palliative patients who would develop intractable cancer pain, as early as possible.Setting/Subjects:Among 385 in-hospital cancer patients from April 1, 2014 to July 31, 2019, who were referred to the palliative care team for cancer-related pain, clinical factors significantly correlated to high-dose opioid use were retrospectively analyzed.Measurements:We conducted a multiple logistic regression analysis to identify variables significantly related to high-dose opioid use (>120 mg/day oral morphine equivalent dose).Results:Independent factors of high-dose opioid use included younger age (odds ratio [OR] 0.965, 95% confidence interval [CI] 0.944-0.986, p = 0.001), respiratory cancers (OR 1.882, 95% CI 1.069-3.312, p < 0.001), and opioid switch (OR 2.869, 95% CI 1.497-5.497, p = 0.001). The percentage of correct classifications of the regression equation was 86.9%.Conclusions:Younger age, respiratory cancers, and opioid switch were related to high-dose opioid use. Our findings may help palliative caregivers to deal with intractable cancer pain in palliative patients, and thus relieve their distress

Synthetic PAMPS gel activates BMP/Smad signaling pathway in ATDC5 cells, which plays a significant role in the gel-induced chondrogenic differentiation
The purposes of this study were to identify signaling pathways that were specifically activated in ATDC5 cells cultured on poly (2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) gel in insulin-free maintenance medium and to evaluate the significance of the determined signaling pathways in the chondrogenic differentiation induced by this gel. In this study, ATDC5 cells cultured on PAMPS gel using the maintenance medium without insulin (PAMPS Culture) were compared with cells cultured on polystyrene using the differentiation medium containing insulin (PS-I Culture). The microarray analysis, Western blot analysis, and real-time PCR analysis demonstrated that the TGF-β/BMP signaling pathway was significantly enhanced at Days 1, 2, and 3 in the PAMPS Culture when compared with the PS-I Culture. Inhibition of the BMP type-I receptor reduced the phosphorylation level of Smad1/5 and expression of type-2 collagen and aggrecan mRNA in the cells accompanied by a reduction in cell aggregation at Day 13 in the PAMPS Culture. The inhibition of the TGF-β/BMP signaling pathway significantly inhibited the chondrogenic differentiation induced by the PAMPS gel. The present study demonstrated that synthetic PAMPS gel activates the TGF-β/BMP/Smad signaling pathway in the ATDC5 cells in the absence of insulin, and that this activation plays a significant role in the chondrogenic differentiation induced by PAMPS gel
Successful Chemotherapy with Carboplatin and S-1 for Thymic Carcinoma: A Case Report
Thymic carcinoma is a rare but aggressive neoplasm. Although there is no clearly optimal first- or second-line chemotherapy regimen for thymic carcinoma, platinum-based chemotherapy has repeatedly been shown to be of benefit to patients with advanced thymic carcinoma. Some case reports have described S-1 as a novel agent with good activity against advanced thymic carcinoma. A 74-year-old female was diagnosed with thymic carcinoma complicated by pleural dissemination and pericardial effusion of carcinomatosa. She was treated with carboplatin on day 1 plus S-1 on days 1-14 in cycles repeated every 3 or 4 weeks. Four cycles of this regimen were administered, and a partial response was confirmed. There were no severe hematological or nonhematological toxicities, and no dose reduction was necessary. To our knowledge, this is the first report to demonstrate the efficacy of combination chemotherapy consisting of carboplatin and S-1 against thymic carcinoma
