Varenicline and Nicotine Replacement Therapy for Smokers Admitted to Hospitals: A Randomized Clinical Trial.

Importance: Varenicline is the most effective sole pharmacotherapy for smoking cessation. If used in combination with nicotine replacement therapy (NRT), cessation rates may be further improved, but the efficacy and safety of the combination need to be evaluated.

Objective: To examine whether hospitalized smokers treated with varenicline and NRT lozenges achieve higher prolonged smoking abstinence rates compared with those treated with varenicline alone.

Diazirine Photoprobes for the Identification of Vancomycin-Binding Proteins.

Vancomycin's interactions with cellular targets drive its antimicrobial activity and also trigger expression of resistance against the antibiotic. Interaction partners for vancomycin have previously been identified using photoaffinity probes, which have proven to be useful tools for exploring vancomycin's interactome. This work seeks to develop diazirine-based vancomycin photoprobes that display enhanced specificity and bear fewer chemical modifications as compared to previous photoprobes.

Telemedicine and gynecologic oncology: caring for patients remotely during a global pandemic.

Background: Telemedicine uses technology to deliver medical care remotely and has been shown to provide similar patient satisfaction and care outcomes compared with in-person visits.

Objective: This study aimed to assess the gynecologic oncology patient telehealth experience.

Study Design: All patients receiving telehealth care between March 23, 2020, to May 14, 2020, from a single institution's gynecologic oncology division were offered postvisit surveys to assess satisfaction.

Meningeal defects and focal cortical dysplasia: an unrecognized relationship? Illustrative case.

Background: Focal cortical dysplasias (FCDs) are a heterogenous cluster of histopathologic entities classically associated with medically refractory epilepsy. Because there is substantial histopathologic variation among different types of FCD, there are likely multiple pathogenic mechanisms leading to these disorders. The meninges are known to play a role in cortical development, and disruption of meningeal-derived signaling pathways has been shown to impact neurodevelopment.

Which smokers enroll in a hospital based smoking cessation trial? Survey of smoking related behaviors, quit attempts, and motivation to quit.

Background: Understanding smoking behaviors in hospital patients who smoke may improve inpatient cessation treatments. This study aimed to describe smoking-related behaviors, past-quit attempts, and self-reported difficulties experienced in quitting among those who enrolled in a smoking cessation trial of varenicline.

Methods: Baseline data were obtained from adult hospitalized smokers (average ≥ 10 cigarettes/day in 4-weeks prior to hospitalization) who enrolled in a randomized, placebo-controlled trial of varenicline ± nicotine lozenges at five Australian public hospitals.

Transfusion Requirements with Hybrid Management of Placenta Accreta Spectrum Incorporating Targeted Embolization and a Selective Use of Delayed Hysterectomy.

Objective: This study compares the number of units of red blood cells (RBCs) transfused in patients with placenta accreta spectrum (PAS) treated with or without a multidisciplinary algorithm that includes placental uterine arterial embolization (P-UAE) and selective use of either immediate or delayed hysterectomy.

Study Design: This is a retrospective study of deliveries conducted at a tertiary care hospital from 2001 to 2018 with pathology-confirmed PAS. Those with previable pregnancies or microinvasive histology were excluded.

Standardization of caregiver and nursing perioperative care on gynecologic oncology wards in a resource-limited setting.

Introduction: In Kampala, Uganda, there is a strong cultural practice for patients to have designated caregivers for the duration of hospitalization. At the same time, nursing support is limited. This quality improvement project aimed to standardize caregiver and nursing perioperative care on the gynecologic oncology wards at the Uganda Cancer Institute and Mulago Specialised Women and Neonatal Hospital.

Placental uterine artery embolization followed by delayed hysterectomy for placenta percreta: A case series.

We describe outcomes of patients with suspected placenta percreta treated with placental uterine artery embolization (P-UAE) followed by delayed hysterectomy. This is a prospective case series of subjects from 2005 to 2018 with suspected placenta percreta who underwent P-UAE at the time of cesarean delivery followed by delayed hysterectomy. Both scheduled and unscheduled surgical cases were included.

Structures of full-length VanR from Streptomyces coelicolor in both the inactive and activated states.

Vancomycin has historically been used as a last-resort treatment for serious bacterial infections. However, vancomycin resistance has become widespread in certain pathogens, presenting a serious threat to public health. Resistance to vancomycin is conferred by a suite of resistance genes, the expression of which is controlled by the VanR-VanS two-component system.

Management of high, moderate, and low penetrance ovarian cancer susceptibility mutations: an assessment of current risk reduction practices.

Objective: Limited information exists regarding risk reduction strategies for women with moderate and low penetrance ovarian cancer susceptibility mutations. We sought to assess current risk reduction practice patterns for carriers of these mutations through a survey of members of the Society of Gynecologic Oncology.

Methods: Society of Gynecologic Oncology members were emailed a survey consisting of two vignettes: (1) a 35-year-old premenopausal woman; (2) a 55-year-old postmenopausal woman with comorbidities.

Patient preferences for attributes of primary surgical debulking versus neoadjuvant chemotherapy for treatment of newly diagnosed ovarian cancer.

Background: Randomized trials have reported conflicting findings on survival for advanced-stage ovarian cancer treated with primary debulking surgery (PDS) versus neoadjuvant chemotherapy with interval debulking; surgical complications and mortality are higher with PDS. We assessed women's preferences for tradeoffs related to this important clinical decision.

Methods: Ovarian cancer patients were recruited to complete a discrete-choice experiment (DCE) consisting of 8 choice tasks presenting experimentally designed treatment alternatives in terms of treatment order, extent of surgery including risk of ostomy, chance of death from surgical complications (1%-10%), readmission for surgical complications (5%-50%), progression-free survival (1-3 years), and overall survival (3-5 years).

Associations between lymphovascular space invasion, nodal recurrence, and survival in patients with surgical stage I endometrioid endometrial adenocarcinoma.

Objective: To investigate the predictive value of lymphovascular space invasion (LVSI) for nodal recurrence and overall survival (OS) in patients with stage I endometrioid endometrial cancer (EC) following surgical staging that included adequate lymph node sampling.

Methods: Retrospective analyses of patients undergoing surgical staging for FIGO stage I endometrioid EC between 1998 and 2015 were performed using an institutional database and the National Cancer Database (NCDB). Using the institutional database, logistic regression modeling identified predictors of nodal recurrence; Cox proportional hazards modeling was used to predict progression-free survival (PFS).

A pilot study of lower extremity lymphedema, lower extremity function, and quality of life in women after minimally invasive endometrial cancer staging surgery.

Objective: The primary aim of this study was to pilot the use of an objective measurement technique to prospectively evaluate the incidence of lower extremity lymphedema (LEL) after minimally invasive staging surgery for endometrial cancer. Secondary objectives included observation of changes in lower extremity function and quality of life in this patient population.

Methods: A prospective evaluation of LEL was performed in 97 women who underwent minimally invasive staging surgery for endometrial cancer using comparative circumferential volume measurements.

Hysterectomy with sentinel lymph node biopsy in the setting of pre-operative diagnosis of endometrial intraepithelial neoplasia: A cost-effectiveness analysis.

Objectives: Sentinel lymph node biopsy (SLNB) may be considered in the setting of a pre-operative diagnosis of endometrial intraepithelial neoplasia (EIN) due to high rates of concurrent invasive cancer. The aim of this study is to compare the cost-effectiveness of different surgical management strategies for a pre-operative diagnosis of EIN.

Methods: A decision model was developed from a third party payer perspective to compare four surgical strategies for the management of EIN: (1) hysterectomy; (2) hysterectomy with frozen section (hysterectomy + frozen); (3) hysterectomy with SLNB (hysterectomy + SLNB); (4) hysterectomy with frozen section and SLNB (hysterectomy + frozen + SLNB).

Near-infrared fluorescence for detection of sentinel lymph nodes in women with cervical and uterine cancers (FILM): a randomised, phase 3, multicentre, non-inferiority trial.

Background: Accurate identification of sentinel lymph nodes in patients with cancer improves detection of metastatic disease and decreases surgical morbidity. We sought to establish whether indocyanine green fluorescent dye is non-inferior to isosulfan blue dye in detecting sentinel lymph nodes in women with cervical and uterine cancers.

Methods: In this non-inferiority, within-patient comparison study, patients aged 18 years or older with clinical stage I endometrial or cervical cancer undergoing curative surgery were randomly assigned 1:1 to lymphatic mapping with isosulfan blue dye (visualised by white light) followed by indocyanine green (visualised by near-infrared imaging), or indocyanine green followed by isosulfan blue dye.

Predicting 6- and 12-Month Risk of Mortality in Patients With Platinum-Resistant Advanced-Stage Ovarian Cancer: Prognostic Model to Guide Palliative Care Referrals.

Objective: Predictive models are increasingly being used in clinical practice. The aim of the study was to develop a predictive model to identify patients with platinum-resistant ovarian cancer with a prognosis of less than 6 to 12 months who may benefit from immediate referral to hospice care.

Methods: A retrospective chart review identified patients with platinum-resistant epithelial ovarian cancer who were treated at our institution between 2000 and 2011.

Use of a novel sentinel lymph node mapping algorithm reduces the need for pelvic lymphadenectomy in low-grade endometrial cancer.

Objectives: To evaluate the capability of a novel sentinel lymph node (SLN) mapping algorithm to reduce the need for pelvic lymphadenectomy (PLND) in patients with low-grade (G1-2) endometrial cancer (LGEC).

Methods: Patients with LGEC underwent evaluation according to a novel lymphatic assessment algorithm during hysterectomy with SLN biopsy at two academic gynecologic oncology programs. Side-specific PLND was only performed if ipsilateral SLN mapping failed and high-risk uterine features were identified on frozen section (FS).

Multidisciplinary approach to manage antenatally suspected placenta percreta: updated algorithm and patient outcomes.

Background: Due to the significant morbidity and mortality associated with placenta percreta, alternative management options are needed. Beginning in 2005, our institution implemented a multidisciplinary strategy to patients with suspected placenta percreta. The purpose of this study is to present our current strategy, maternal morbidity and outcomes of patients treated by our approach.

Prospective Evaluation of Lymph Node Processing at Staging Surgery for High-grade Endometrial Cancer.

To determine whether the processing of additional adipose tissue collected during lymph node (LN) dissection results in the identification of additional LNs during endometrial cancer (EC) staging and to determine if the division of LNs into nodal basin-specific specimens has an effect on the number of LNs identified during EC staging. A prospective randomized controlled trial was performed on women with high-grade EC undergoing surgical staging. Subjects were randomized to collection of LNs into nodal basin-specific containers on the randomized side versus simple labeling on the nonrandomized side.
