Chae Su Hyun,Lee Chulmin,Yoon Sang-Hee,Shim Seung-Hyuk,Lee Sun Joo,Kim Soo-Nyung,Chung Sochung,Lee Ji Young 대한의학회 2021 Journal of Korean medical science Vol.36 No.1

Background: To identify sarcopenia as a predictive prognostic factor of ovarian cancer in terms of survival outcome in patients with early-stage ovarian cancer. Methods: Data of Konkuk University Medical Center from March 2002 to December 2017 were reviewed retrospectively. Eighty-two patients who underwent surgery due to early-stage (International Federation of Gynecology and Obstetrics stage I/II) ovarian cancer and had computed tomography (CT) images taken at the initial diagnosis were included. The initial CT scan images were analyzed with SliceOmatic software (TomoVision). A sarcopenia cutoff value was defined as a skeletal muscle index of ≤ 38.7 cm2 /m2 . Overall survival (OS) times were compared according to the existence of sarcopenia, and subgroup analyses were performed. Results: A Kaplan-Meier analysis showed a significant survival disadvantage for patients with early-stage ovarian cancer when they had sarcopenia (P < 0.001; log-rank test). Sarcopenia remained a significant prognostic factor for OS in early-stage ovarian cancer, in a Cox proportional hazards model regression analysis (HR, 21.9; 95% CI, 2.0–199.9; P = 0.006). Conclusion: This study demonstrated that sarcopenia was predictive of OS in patients with early-stage ovarian cancer. Further prospective studies with a larger number of patients are warranted to determine the extent to which sarcopenia can be used as a prognostic factor in ovarian cancer.

목적: To compare the perioperative outcomes between transvaginal and conventional laparoscopic surgery for ovarian dermoid cysts in a case-matched manner. 방법: Using a prospectively gathered database of patients with dermoid cyst in our institution, we analyzed all consecutive patients who underwent transvaginal or conventional laparoscopy between 2007 and 2013. Patients of transvaginal group were matched with conventional group (at 1:1 ratio) based on age, body mass index, diameter of tumor, bilaterality, previous abdominal surgery history, and operative procedures. The main outcome measurements included surgical and follow-up outcomes. 결과: One-hundred sixty-six patients undergoing transvaginal laparoscopy for dermoid cyst were matched with patients undergoing conventional laparoscopy. One patient (0.6%) in conventional group but no cases in transvaginal group required conversion to laparotomy. The operating time, estimated blood loss, transfusions, and length of postoperative hospital stay were similar. Perioperative complications occurred in one patient (0.6%) in transvaginal group and two patients (1.1%) in conventional group. Transvaginal group showed significantly lower visual analog score [expressed as median (interquartile range)] for pain at 3 hours [3 (3-4) vs. 4 (3-4), p=0.001], 8 hours [2 (2-3) vs. 3 (3-4), p<0.001] and 16 hours [3 (2-3) vs. 3 (3-4), p<0.001] after surgery. After a median follow-up time of 36 months (range, 3-78 months), one patient (0.6%) in transvaginal group and three patients (1.8%) in conventional group showed recurrent dermoid cyst (p=0.37). 결론: This is the first matched cohort study comparing transvaginal versus conventional laparoscopic surgery for dermoid cyst. Transvaginal group showed similar feasibility and efficacy with conventional group in the management of dermoid, while it is associated with less postoperative pain and better cosmetic effect. This finding should be confirmed in the future randomized controlled trial.

<P><B>Abstract</B></P> <P>Implantable electronic medical devices (IEMDs) can potentially be used to solve various clinical problems including the monitoring of chronic diseases and electro-organ transplantation. Several recently introduced techniques based on implantable devices that exploit novel metal- or carbon-based hybrid materials are biocompatible owing to their encapsulation in nontoxic polymers. However, such techniques limit the correct functioning of implantable devices, resulting in frequent replacement, difficult miniaturization, and inflammatory side effects in the body. Here, we describe a new technique for application to IEMDs that is capable of providing energy storage using the natural ions of body fluids as electrolytes in a supercapacitor (or ultracapacitor). The system is constructed with a solar cell for energy harvesting and a supercapacitor for energy storage. We assembled IEMDs with two biocompatible electrodes, specifically, MnO<SUB>2</SUB> nanoparticles affixed to multi-walled carbon nanotubes as the positive electrodes and phosphidated activated carbon as the negative electrodes. From the obtained result, this work can be further extended to the use of rats. This technique avoids the problems of performance degradation and toxicity that normally limits the reaction that is permissible in extracellular fluid. We present this concept schematically. The two biocompatible electrodes were successfully implanted into the subcutaneous layer of a rat's skin with both electrodes showing stable performance in use as parts of a supercapacitor. These findings establish a platform for potential biocompatible materials for implantable energy storage devices.</P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
