Article Synopsis
  • The study examined how certain genomic biomarkers can predict treatment outcomes for patients with adenocarcinoma of the uterine cervix undergoing chemoradiotherapy (CRT).
  • It analyzed data from 21 patients using tissue samples and next-generation sequencing to identify key genetic alterations affecting survival rates.
  • Key findings indicated that MCL1 gene amplification and lower TNF-α levels were linked to worse disease-free survival, with specific prognostic implications suggested for better patient management.

Background: Dysmenorrhea and stroke are health problems affecting women worldwide in their day-to-day lives; however, there is limited knowledge of the stroke risk in women with dysmenorrhea, and there have been no studies assessing the specific distribution of stroke subtypes. This case-control study assessed stroke subtypes by age and the role of comorbidities in women with dysmenorrhea.

Methods And Findings: Data obtained between 1997 and 2013 from Taiwan's health insurance database identified 514 stroke cases and 31,201 non-stroke controls in women with dysmenorrhea aged 15-49 years.

Aim: To compare the advantage of image-guided brachytherapy (IGBT) over conventional two-dimensional brachytherapy (2DBT) in patients with advanced cervical squamous cell carcinoma.

Patients And Methods: This study included 253 patients with stage IB2-IVA diseases treated with two schemes of brachytherapy. One hundred and thirty-six patients received 2DBT, whereas 117 patients received IGBT.

Objective: Choice of hysterectomy and adjuvant treatment for International Federation of Gynecology and Obstetrics (FIGO) 2009 stage II endometrioid endometrial cancer (EEC) is still controversial. Aims of this study were to evaluate survival benefits and adverse effects of different hysterectomies with or without adjuvant radiotherapy (RT), and to identify prognostic factors.

Methods: The patients at 14 member hospitals of the Taiwanese Gynecologic Oncology Group from 1992 to 2013 were retrospectively investigated.

Background: Remodeling spacing factor 1 (RSF-1/HBXAP) has been linked to a variety of cancer types, however, its roles and the therapeutic potential are not clear in cervical cancer.

Methods: RSF-1 expression in cancer tissues was analyzed by immunohistochemical staining followed by statistical analysis with SPSS. Anti-RSF-1 studies were performed by treating cells with specific siRNA or a dominant mutant form (RSF-D4).

Objective: To assess risks of postpartum hypertension and diabetes mellitus (DM) for women with hypertension during pregnancy (HDP) with and without gestational DM (GDM).

Patients And Methods: From insurance data of 15- to 44-year-old women with pregnancy in 2000-2011, we established an HDP/GDM cohort (n=1270), an HDP/non-GDM cohort (n=5077), and a comparison cohort without either disorder (n=12,594), frequency matched by age and year of pregnancy. Postpartum hypertension and DM were assessed before 2012.

Article Synopsis
  • The study investigates the impact of two specific probiotics, Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14, on reducing Group B Streptococcus (GBS) colonization in pregnant women.
  • A total of 110 GBS-positive pregnant women were randomly assigned to receive either probiotics or a placebo before bedtime until delivery, with follow-up GBS testing before childbirth.
  • Results showed that 42.9% of women in the probiotic group tested negative for GBS by delivery, compared to only 18.0% in the placebo group, indicating probiotics may effectively reduce GBS colonization.

Introduction: Invasive procedures including loop electrosurgical excision, cervical conization, and endometrial sampling are often recommended when atypical glandular cells (AGC) are detected on Pap smear with unsatisfactory colposcopy. These invasive procedures may result in patient anxiety, increased medical expense, and increasing the risk of preterm delivery in subsequent pregnancies. This study was performed to assess methylation biomarkers in the triage of AGC on Pap smear for invasive procedures.

Objective: The objective of this study was to assess prospectively the clinical outcomes of low-dose prophylactic extended-field, intensity-modulated radiotherapy (IMRT) plus concurrent weekly cisplatin for patients with stage IB2-IIIB cervical cancer, positive pelvic lymph nodes (PLNs), and negative para-aortic lymph nodes (PALNs).

Methods: Thirty-two patients with stage IB2-IIIB cervical cancer with positive PLN and negative PALN were included prospectively. All lymph nodes were assessed with positron emission tomography.

Objective: To evaluate the clinical outcome and parameters related to coexisting endometrial carcinoma in women with tissue-diagnosed endometrial hyperplasia.

Methods: Between January 1991 and December 2009, three hundred and eighty-six patients with the presumptive diagnosis of endometrial hyperplasia were retrieved. Among these, one hundred and twenty-five patients were identified as having coexisting endometrial carcinoma in hysterectomy specimens.

Exercise can improve and maintain neural or muscular function, but the effects of exercise in physiological adaptation to paralysis caused by botulinum toxin A has not been well studied. Twenty-four rats were randomly assigned into control and treadmill groups. The rats assigned to the treadmill group were trained on a treadmill three times per week with the running speed set at 15 m/min.

Background: Early rehabilitation for children with developmental delay without a defined etiology have included home and clinic programs, but no comparisons have been made and efficacy is uncertain. We compared a weekly visit for institutional-based therapy (IT) to IT plus a structured home activity program (HAP).

Methods: Seventy children who were diagnosed with motor or global developmental delay (ages 6-48 months and mean developmental age 12.

Cesarean section defect had been found to be one of the causes of prolonged bleeding in women with previous cesarean delivery. Lin's hysteroscopy (TCR)-metroplasty method had focused on 4 predisposed anatomical defects, which ensured correction of the cesarean section defect. With this simple procedure, the patients had greatly improved their quality of life, as well as discomfort.

Objective: This study aimed to elucidate the possible relationship between surgical blood loss (SBL) and medical outcomes of laparoscopic-assisted vaginal hysterectomy (LAVH).

Materials And Methods: Patients who underwent LAVH performed by the same surgeon for benign gynecologic diseases from 2004 to 2006 were analyzed retrospectively. Patients were divided into two groups according to the amount of SBL (< 150 mL or > or = 150 mL, 75th percentile of mean SBL).
