Objective: Abdominal Radical hysterectomy (ARH) with pelvic lymph node assessment is considered the standard treatment for early-stage cervical cancer. Accepted routes have previously included laparoscopic or robotic approaches (LRH). Laparoscopy-assisted vaginal or vaginal radical hysterectomy (LVRH) are performed in some centers.

Background: Social, familial, and physiological stressors may put maternal-infant bonding at risk. Therefore, it is plausible that the stressful conditions brought on by COVID-19 could influence maternal-infant bonding. This study aimed to elucidate the contribution of COVID-19-related experience to variance in maternal-infant bonding, beyond that of established risk factors and as moderated by social support.

Exposure to repeated sexual trauma, particularly during childhood, often leads to protracted mental health problems. Childhood adversity is specifically associated with complex posttraumatic stress disorder (PTSD) presentation, which is particularly tenacious and treatment refractory, and features severe emotion dysregulation. Augmentation approaches have been suggested to enhance treatment efficacy in PTSD thus integrating first-line psychotherapy with mechanistically informed self-neuromodulation procedures (i.

Background: The hippocampus plays an important role in the pathophysiology of posttraumatic stress disorder (PTSD) and its prognosis. Accumulating findings suggest that individuals with larger pretreatment hippocampal volume are more likely to benefit from PTSD treatment, but the mechanism underlying this effect is unknown. We investigated whether further increase in hippocampal volume during treatment explains the better prognosis of individuals with greater pretreatment hippocampal volume.

Aim: Childhood sexual abuse (CSA) among women is an alarmingly prevalent traumatic experience that often leads to debilitating and treatment-refractory posttraumatic stress disorder (PTSD), raising the need for novel adjunctive therapies. Neuroimaging investigations systematically report that amygdala hyperactivity is the most consistent and reliable neural abnormality in PTSD and following childhood abuse, raising the potential of implementing volitional neural modulation using neurofeedback (NF) aimed at down-regulating amygdala activity. This study aimed to reliably probe limbic activity but overcome the limited applicability of functional magnetic resonance imaging (fMRI) NF by using a scalable electroencephalogram NF probe of amygdala-related activity, termed amygdala electrical-finger-print (amyg-EFP) in a randomized controlled trial.

Post-traumatic stress symptoms (PTSS) following childbirth are common within a stressful environment and are mitigated by social support. During the COVID-19 pandemic, an increase in such symptoms has been reported. The current study aims to longitudinally model the influence of general and pandemic-specific risk and protective factors on the temporal unfolding of symptoms among postpartum women.

Background: Contemporary views of emotion dysregulation in post-traumatic stress disorder (PTSD) highlight reduced ability to flexibly select regulatory strategies according to differing situational demands. However, empirical evidence of reduced regulatory selection flexibility in PTSD is lacking. Multiple studies show that healthy individuals demonstrate regulatory selection flexibility manifested in selecting attentional disengagement regulatory strategies (e.

Aim: To assess the efficacy of a novel neurofeedback (NF) method, targeting limbic activity, to treat emotional dysregulation related to premenstrual dysphoric disorder (PMDD).

Methods: We applied a NF probe targeting limbic activity using a functional magnetic resonance imaging-inspired electroencephalogram model (termed Amyg-EFP-NF) in a double-blind randomized controlled trial. A frontal alpha asymmetry probe (AAS-NF), served as active control.

Stress-related disorders (SRD) disproportionately affect women. Cortisol blunting, a failure to demonstrate a typical rise and fall of cortisol in response to stress, is associated with SRDs and has been found to be more pronounced among women. Cortisol blunting relates to both sex as a biological variable (SABV; e.

Objective: The use of chemoradiation in patients with stage IVB cancer of the cervix was evaluated to determine if definitive treatment offers benefit.

Methods: A database of 546 patients with cancer of the cervix treated between January 2005 and May 2021 at a tertiary academic medical center was reviewed retrospectively to identify patients with stage IVB disease. Log rank test, regression analysis, and the Kaplan-Meier method were used to identify and compare variables and estimate progression free survival and overall survival.

Minimally invasive surgery for the treatment of macroscopic cervical cancer leads to worse oncologic outcomes than with open surgery. Preoperative conization may mitigate the risk of surgical approach. Our objective was to describe the oncologic outcomes in cases of cervical cancer initially treated with conization, and subsequently found to have no residual cervical cancer after hysterectomy performed via open and minimally invasive approaches.

Background: Surgeon-administered transversus abdominis plane block is a contemporary approach to providing postoperative analgesia, and this approach is performed by transperitoneally administering local anesthetic in the plane between the internal oblique and transversus abdominis muscles to target the sensory nerves of the anterolateral abdominal wall. Although this technique is used in many centers, it has not been studied prospectively in patients undergoing a midline laparotomy.

Objective: This study aimed to evaluate whether surgeon-administered transversus abdominis plane block reduces postoperative opioid requirements and improves clinical outcomes.

Article Synopsis
  • - Endometrial carcinoma (EC) has four molecular subtypes, with the no specific molecular profile (NSMP) subtype being the most common, found in about 50% of cases. Although it generally has a favorable prognosis, it includes a wide range of tumor characteristics.
  • - This study analyzed 1,110 NSMP ECs to identify factors that could predict outcomes, focusing on clinicopathologic features, immunohistochemical markers, and genetic information to categorize tumors as low-risk or high-risk.
  • - Key findings revealed that low-risk NSMP tumors (grade 1-2, ER-positive) had a 5-year disease-specific death rate of only 1.6%, in contrast to high-risk NS

Article Synopsis
  • Recent research indicates that the type of molecular subtype in endometrial cancer (EC) can help predict clinical outcomes and guide treatment decisions.
  • In a study involving 2,472 EC patients, adjuvant chemotherapy showed significant benefits for patients with p53abn subtype but did not provide additional benefits for those with MMRd subtype.
  • The findings suggest that while adjuvant chemotherapy improves survival in p53abn EC patients, it may not enhance outcomes for MMRd patients, highlighting the need for further research tailored to specific molecular subtypes.
