Topical Vancomycin for Neurosurgery Wound Prophylaxis

This study is a collaboration between New York Presbyterian (NYP)-Columbia and NYP-Cornell that seeks to evaluate the use of topical vancomycin and its reduction on surgical site infection (SSI) in neurosurgical procedures. Adult patients undergoing neurosurgery at either institution will be eligible for participation in this randomized control trial. Patients randomized to the treatment group will receive 2g of vancomycin applied as a powder or paste to the wound site and/or bone flap. Subjects in the control group will receive the current standard of care without topical vancomycin. All subjects will undergo swabbing of the anterior nares and the surgical site prior to surgery, once 10-14 days following the operation and 90 days following the operation. The primary outcome measure will be surgical site infection, assessed daily throughout the hospital stay, at the first follow-up visit, and by telephone at 14-30 days and 90 days (+/- 7 days). Secondary outcomes will include length of hospital stay, length of intensive care stay, rate of reoperation and patient mortality. In addition, systemic vancomycin levels will be assessed at 6 hours and 20 hours postoperatively in each patient. Patients who have an external ventricular drain in place will have vancomycin levels assessed daily. In patients who have cranial drains placed, vancomycin concentrations will be analyzed from daily in wound drainage. Skin and nasal flora will be analyzed to assess the impact of topical vancomycin on the patient microbiome. Although there has been a decrease in the incidence of infections following craniotomy secondary to prophylactic intravenous antibiotics, proper sterile techniques, and other interventions, SSIs continue to significantly impact morbidity, mortality, and cost burden. Although never studied in neurosurgical procedures other than instrumented spine, the application of topical vancomycin to the surgical site prior to wound closure has demonstrated a reduction in SSIs in spine, cardiac and ophthalmologic procedures. The benefits of using prophylactic vancomycin topically, as opposed to intravenously, include reduced systemic levels of the drug, and therefore, a decreased probability of adverse events related to the drug, such as inducing resistance among the native flora. The investigators propose a single-blinded randomized control trial to evaluate the effectiveness of topical vancomycin in reducing SSIs rates following neurosurgical procedures.

The Impact of Physical Exercise on Sleep in Colorectal Cancer Patients During Prehabilitation Period

Main objective: To evaluate the bidirectional relationships between physical exercise and sleep parameters, as a part of multimodal prehabilitation intervention, on pre- and postoperative outcomes in surgical patients with colorectal cancer, in an RCT. Secondary objective: to determine whether the levels of anxiety and depression affect these relationships. Objectives are based on the overarching hypothesis that is sleep and physical activity influence each other through complex, reciprocal interactions including multiple physiological and psychological pathways. To achieve this, providing a multimodal prehabilitation, specifically physical exercise, involved in mental and physical health through different mechanisms, i.e., improving physical functioning and fitness, reducing side effects of cancer treatments, preventing bone loss and weight gain, improving the quality of life and sleep, decreasing symptoms of fatigue and depression. The present is a pilot study aiming to evaluate the bidirectional relationships between sleep and physical exercise, and the preliminary outcome has important implications for informing both clinical and public health practice. Research question: Does a multimodal intervention including physical exercise improve sleep quality and duration compared to standard of care, during the perioperative period? Conversely, does a better sleep quality and duration increases the level of physical exercise during the perioperative period? How the level of anxiety and depression will affect these relationships? If the Prehabilitation program specifically physical exercise will positively affect sleep quality and duration after surgery, in the way to be a protective factor of sleep to not be reduced by up to 55% compared to those receiving standard of care?

Locoregional Treatment and Palbociclib in de Novo, Treatment Naive, Stage IV ER+, HER2- Breast Cancer Patients

Approximately 3.5% to 6% of newly diagnosed breast cancer patients are stage IV metastatic. De novo metastatic breast cancer accounts for 20% to 25% of these cases. Despite a decrease in mortality in Europe and North America due to early detection and access to treatment, breast cancer remains the 2?? leading cause of cancer deaths in developed countries after lung cancer and the world's leading cause. In the ESME French national retrospective cohort (NCT03275311), the newly diagnosed estrogen receptor (ER)-positive and HER2-negative (luminal) metastatic patients had a 59.1 months overall survival (OS) for pre-menopausal women and 44.7 months for postmenopausal women. In the same cohort, the median OS was 47.4 months for de novo metastatic patients with hormone receptor (HR)-positive / HER2-negative breast cancer. The most important current treatment for metastatic breast cancer remains systemic therapy. Surgery and radiation are mainly used to treat symptoms. However, more than 15 retrospective studies have assessed the impact of locoregional treatment on relapse and OS. These studies suggested an improvement of the OS in patients with de novo metastatic breast cancer thanks to the addition of locoregional treatment to systemic therapy. Recent data from the ESME cohort suggest that patients with de novo luminal or HER2-positive metastatic breast cancer may benefit from local treatment of the primary tumor. Several prospective trials have attempted to demonstrate the benefit of locoregional treatment with mixed results. This can be explained by a limited power of statistical analysis, on the recruitment of patients with breast cancer of all types, and on a limited access to effective systemic therapies in some cases and all before the area of anti CD4/6 which is the current standard treatment in patients with HR-positive / HER2-negative luminal metastatic disease. However, guidelines indicate that a "multimodal approach, including curative locoregional treatments, should be considered". As a result, many clinicians offer locoregional treatment of the primary tumor, especially if there is a good response to the first line of systematic treatment. Taken together, these data underscore the need for an evaluation of the value of combined therapy - endocrine therapy - CDK4/6 inhibitor and locoregional treatment - in this population of patients with newly diagnosed HR-positive / HER2-negative breast cancer.
