Near zero-strain silicon oxycarbide interphases for stable Li-ion batteries.

We investigate silicon oxycarbide nanotubes that incorporate Si, SiC, and silicon oxycarbide phases, which exhibit near zero-strain volume expansion, leading to reduced electrolyte decomposition. The composite effectively accommodates the formation of -LiSi, as validated by TEM analyses and electrochemical tests, thereby proposing a promising solution for Li-ion battery anodes.

Impact of community health interventions on maternal and child health indicators in the upper east region of Ghana.

Background: This paper reports on results of a health system strengthening implementation research initiative conducted the Upper East Region of northern Ghana. Transformative interventions to accelerate and strengthen the health delivery were implemented that included empowering community leaders and members to actively participate in health delivery, strengthening the referral systems through the provision of community transport systems, providing basic medical equipment to community clinics, and improving the skills of critical health staff through training.

Methods: A mixed method design was used to evaluate the impact of the interventions.

Design Principles for Fluorinated Interphase Evolution via Conversion-Type Alloying Processes for Anticorrosive Lithium Metal Anodes.

Over the past decade, lithium metal has been considered the most attractive anode material for high-energy-density batteries. However, its practical application has been hindered by its high reactivity with organic electrolytes and uncontrolled dendritic growth, resulting in poor Coulombic efficiency and cycle life. In this paper, we propose a design strategy for interface engineering using a conversion-type reaction of metal fluorides to evolve a LiF passivation layer and Li-M alloy.

Role of reactive thrombocytosis after primary cytoreductive surgery in advanced ovarian cancer.

We investigated the incidence of reactive thrombocytosis after maximal cytoreductive surgery in advanced epithelial ovarian cancer (EOC) and its role in patient survival. We retrospectively reviewed the electronic medical records of patients who underwent primary cytoreductive surgery for advanced EOC from 1 January 2012 to 31 December 2017. We analyzed the serum platelet counts at various time points from before surgery, during the peri-operative period, and after each cycle of adjuvant chemotherapy.

Comparison of Surgical Outcomes of Hysterectomy by Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) versus Single-Port Access (SPA) Surgery.

Single-port access (SPA) laparoscopic surgery and vaginal natural orifice transluminal endoscopic surgery (vNOTES) have many advantages. The objective of the present study is to compare patient characteristics, operative details, and postoperative outcomes between the two surgical methods. Patients who were planned to undergo vNOTES or SPA laparoscopic surgery between April 2020 and June 2021 were prospectively enrolled.

Clinical outcome of pulmonary lymphangitic carcinomatosis in gynecologic malignancy: A single-institution experience.

Objective: Pulmonary lymphangitic carcinomatosis (PLC) is a rare event of metastatic lung disease in advanced gynecologic malignancy. Nonspecific symptoms of patients and difficulties in detection of PLC often result in a delayed diagnosis. In this study, we evaluated the clinical outcomes of PLC in patients with gynecologic cancer.

The prevention of postoperative port-site adhesion following single-port access (SPA) laparoscopic surgeries.

No studies have examined the issue of intraabdominal port-site adhesion following single-port access (SPA) laparoscopic surgeries. The purpose of the present study was to investigate the clinical effects of temperature-sensitive adhesion barrier solution in preventing periumbilical adhesion in SPA laparoscopy. This was a prospective, single-arm study in which patients were given GUARDIX-SGTM after SPA laparoscopic surgery for benign gynecologic diseases.

pelvic resection of ovarian cancer with rectosigmoid colectomy: a literature review.

Maximal cytoreductive surgery is an important prognostic factor in advanced epithelial ovarian cancer (EOC). To achieve maximal cytoreductive surgery, en bloc pelvic resection with rectosigmoid colectomy can be an effective surgical strategy. This surgical methodology was first described in 1968 as "radical oophorectomy.

The implementation of enhanced recovery after surgery protocols in ovarian malignancy surgery.

The enhanced recovery after surgery (ERAS) refers to multimodal interventions to reduce the length of hospital stay and complications at various steps of perioperative care. It was first developed in colorectal surgery and later embraced by other surgical disciplines including gynecologic oncology. The ERAS Society recently published guidelines for gynecologic cancer surgeries to enhance patient recovery.

Hysterectomy and Adnexal Procedures by Vaginal Natural Orifice Transluminal Endoscopic Surgery (VNH): Initial Findings From a Korean Surgeon.

To evaluate feasibility and safety of hysterectomy and adnexal procedures by vaginal natural orifice transluminal endoscopic surgery (vNOTES). This is a prospective observational study at a tertiary center and teaching University hospital. We enrolled prospectively 34 patients with benign diseases sequentially.

Anti-Cancer Activity of AsO and its Efficacy in a Series of Patient-Derived Xenografts for Human Cervical Cancer.

Purpose: To investigate the anti-cancer effects of tetraarsenic hexoxide (TAO, AsO) in cervical cancer cell lines and in a series of patient-derived xenograft (PDX) mouse models.

Methods: Human cervical cancer cell lines, including HeLa, SiHa and CaSki, and human umbilical vein endothelial cells (HUVECs), were used to evaluate the anti-cancer activity of TAO. Cellular proliferation, apoptosis, and enzyme-linked immunosorbent assay (ELISA) for matrix metallopeptidase 2 (MMP-2) and 9 (MMP-9) were assessed.

Establishing a nurse-managed health center for the urban poor in Dhaka, Bangladesh.

Objectives: Despite the rise in community health problems in populations living in urban slums, activities of community health nurses are limited in Bangladesh. This study aimed to describe how a nurse-managed health center (NMHC) was developed in Dhaka, Bangladesh.

Design: An exploratory-descriptive research design was used.

Comparison of Laparoscopy and Laparotomy for Para-Aortic Lymphadenectomy in Women With Presumed Stage I-II High-Risk Endometrial Cancer.

To compare laparoscopic surgery to laparotomy for harvesting para-aortic lymph nodes in presumed stage I-II, high-risk endometrial cancer patients. Patients with histologically proven endometrial cancer, presumed stage I-II with high-risk tumor features who had undergone hysterectomy, bilateral salpingoophorectomy, or pelvic and para-aortic lymphadenectomy by either laparoscopy or laparotomy in Samsung Medical Center from 2005 to 2017 were retrospectively investigated. The primary outcome was para-aortic lymph node count.

Uterine artery ligation at its origin following retroperitoneal space development decreases blood loss during single-port total laparoscopic hysterectomy.

Objective: This study aimed to determine risk factors associated with the failure of uterine artery ligation at its origin following development of the retroperitoneal space (UALr) and evaluated its efficacy in decreasing estimated blood loss (EBL) during single-port total laparoscopic hysterectomy (SP-TLH).

Pharmacogenomic analysis of patient-derived tumor cells in gynecologic cancers.

Background: Gynecologic malignancy is one of the leading causes of mortality in female adults worldwide. Comprehensive genomic analysis has revealed a list of molecular aberrations that are essential to tumorigenesis, progression, and metastasis of gynecologic tumors. However, targeting such alterations has frequently led to treatment failures due to underlying genomic complexity and simultaneous activation of various tumor cell survival pathway molecules.

Pretreatment Lymph Node Metastasis as a Prognostic Significance in Cervical Cancer: Comparison between Disease Status.

Purpose: Lymph node metastasis (LNM) is the most significant prognostic factor in cervical cancer that was recently incorporated into the International Federation of Gynecology and Obstetrics (FIGO) staging system. This study was performed to evaluate whether the prognostic significance of LNM differs according to disease status.

Materials And Methods: Patients with FIGO stage IB or higher cervical cancer who had pretreatment computed tomography and/or magnetic resonance imaging studies as well as long-term follow-up were enrolled in this retrospective study.
