OBJECTIVE The Society of Obstetricians and Gynaecologists of Canada (SOGC) and the Society of Gynaecologic Oncology of Canada (GOC) recommend complete removal of the fallopian tubes as a permanent contraceptive method because of its association with a reduced risk of ovarian cancer. Currently, many women are not offered bilateral salpingectomy as an alternative to tubal ligation for permanent contraception. METHOD As part of a quality improvement initiative, we reviewed all cases of sterilization performed at our university centre between 1 January and 31 December 2018. A literature review of the clinical and ethical considerations that prevent clinicians from offering bilateral salpingectomy as permanent contraception is also presented. RESULTS The records of 111 women who underwent tubal sterilization were reviewed. Of these, 31.5% underwent bilateral salpingectomy; 46.8% underwent tubal fulguration; 12.6% underwent clip ligation; and 9.1% underwent tubal implant ligation (Essure). According to the information on file, only 36.3% of women were offered bilateral salpingectomy, and of these, 83.8% chose this method. CONCLUSION Bilateral salpingectomy should be offered to all women seeking permanent contraception. The benefits and very low risks associated with this procedure should make it a first choice option. OBJECTIVE To assess the prevalence and characteristics of neuropathic pain (NP) at diagnosis of head and neck squamous cell carcinoma (HNSCC) and its impact on nutritional status and treatment tolerance. MATERIALS AND METHODS Patients treated for HNSCC between January 1, 2018 and January 30, 2019 were included. Pain was assessed prospectively on the DN2 and NSPI scales. Epidemiological characteristics, nutritional status and treatment tolerance were collected. Two groups were distinguished according to absence or presence of neuropathic pain (NP-, NP+). RESULTS Sixty patients were included. NP prevalence at diagnosis was 54%, mainly involving locally advanced oral cavity and oropharyngeal tumors. There was a significant intergroup difference in nutritional status, with 62% malnutrition in NP+ versus 32% in NP- (p=0.0321). There was no such difference in tolerance. CONCLUSION NP is frequent at diagnosis of HNSCC. Early diagnosis on a simple validated score can help improve quality of life and nutritional status. INTRODUCTION The current standard of care for advanced high grade serous ovarian cancer (HGSC) comprises a combination of debulking surgery and platinum-based chemotherapy given in the neoadjuvant or adjuvant setting. In the neoadjuvant setting, patients usually undergo 3 cycles of chemotherapy followed by interval cytoreductive surgery (ICS), then 3 further cycles of chemotherapy. However, the optimum timeframe to administer chemotherapy before and after ICS remains unclear. We therefore examine the survival impact of the interval between pre- and post-operative chemotherapy in patients undergoing ICS in a well-established patient cohort. Factors leading to "delays" in recommencing post-operative chemotherapy were also examined. METHODS The study comprises of a retrospective cohort of 205 cases with FIGO stage III and IV HGSC undergoing ICS. The duration of the interval between pre-operative and post-operative chemotherapy was correlated with progression-free (PFS) and overall survival (OS). Univariate and multivariate analyses were constructed to identify factors associated with survival and prolonged chemotherapy interruption. RESULTS The median interval between pre-operative and post-operative chemotherapy was 63 days. Multivariate analyses revealed macroscopic residual disease (HR2.280, 95% CI1.635-3.177, p ≤ 0.001) and interruption of chemotherapy >10 weeks (HR1.65, 95%CI1.201-2.290, p = 0.002) were associated with poorer OS. Existing medical comorbidities and longer hospital stay were independent prognostic factors for prolonging the chemotherapy interruption. https://www.selleckchem.com/products/pirtobrutinib-loxo-305.html CONCLUSION Our study recommends that interruption to chemotherapy to allow patients to undergo ICS should be ≤10 weeks; otherwise, OS is significantly impacted. Patients with pre-existing medical comorbidities should receive additional support pre- and post-operatively to keep the chemotherapy interruption to a minimum. The ubiquitous presence of aluminum in the environment leads to a high likelihood of human exposure. Neurotoxicity of the trivalent cationic form of this metal (Al3+) occurs in the central nervous system via accumulation of Al in cells of neural origin, including neural progenitor cells (NPCs). NPCs play a key role in the development and regeneration of the brain throughout life; therefore, this metal may contribute to neuropathological conditions. Here, we evaluated the effects of different Al3+ concentrations (0-50 μM) on the purinergic system of NPCs isolated from embryonic telencephalons, cultured as neurospheres. Al3+ adhered to the cell surface of neurospheres reducing extracellular ATP release, as well as ATP, ADP, and AMP hydrolysis by NTPDase and 5'-nucleotidase, respectively. In addition, impaired nucleotide release by Al3+ reduced P2Y1 and adenosine A2A receptors expression in differentiated neurospheres. These receptors are crucial for NPC proliferation during brain development and self-repair against external stimuli, such as metal exposure. Thus, Al3+ represents an environmental agent linked to neurodegeneration through alterations in the ATP-signalling pathway, proving to be a potential mechanism associated with NPC proliferation and brain degeneration. OBJECTIVES To determine the effect of a novel low volume high intensity concurrent training regimen and warm-up on physiological performance and musculoskeletal injury in Australian recruits. DESIGN Controlled longitudinal intervention. METHODS Military recruits completed 12 weeks of either experimental (EXP n=78, 6-8RM resistance loads, and high intensity intervals) or basic military (CON n=69, usual practice) matched for total sessions and time. Endurance (3.2km 22kg-load carriage, V˙O2 peak, multi-stage fitness test (MSFT)), 1RM strength and local muscle endurance (bench, squat, box-lift and push-ups) and power (squat jump) were assessed at Weeks 1,6,12. Body composition, physical activity (PAC·min-1) and heart rate reserve (HRR%), were assessed at Weeks 2,7,9. Musculoskeletal injury and mechanism were recorded. Two-way repeated measures ANOVA interaction (group×time), mean difference and effect size (ES) are reported p≤0.05. RESULTS A significant interaction over 12 weeks was observed for load carriage (ES -0.
