MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Targeted treatment options for metastatic triple negative breast cancer (TNBC) are limited. TNBCs are associated with a high frequency of PTEN loss, which can lead to activation of the mTOR pathway and tumor proliferation but may be reversible with the mTOR inhibitor everolimus. A prior phase II single arm trial of carboplatin and everolimus in patients with advanced TNBC demonstrated good tolerability and preliminary efficacy. The current study is a randomized phase II trial comparing carboplatin and everolimus with carboplatin alone in patients with metastatic TNBC.
We found that the combination of carboplatin and everolimus reduced the risk of progression or death by 52%. The regimen was well tolerated and provides a promising treatment option for patients with advanced TNBC.

MedicalResearch.com: What is the background for this study?
Response: The germline genome of each individual person has a unique combination of millions of genetic variants that influence virtually all biological processes throughout life, including cancer evolution. In this study, we have investigated the impact of germline variants – genetic defects one is born with – on gene expression and protein abundance in tumors across cancer types.
MedicalResearch.com: Would you describe the technique of precision peptidomics?
Response: We have leveraged a cohort of 1,064 patients with multiple cancer types to explore the impact of germline variations on cancer-relevant genes through multiple-omics layers: from DNA to RNA, protein abundance and post-translational modifications. To assess the effects of coding variants and their association with cognate proteins, we used precision peptidomics, which is the quantification of peptides carrying genetic variants from individual patients. Through this approach, we mapped 337,469 protein coding germline variants onto patient peptides, revealing their potential impact on protein modifications, protein stability, allele-specific expression, and protein structure by leveraging the relevant protein databases.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Sleep apnea is associated with incident cardiovascular disease, and is a common chronic condition affecting over a billion people worldwide. In diagnosing and treating sleep apnea, it is imperative to establish the type of sleep apnea—whether it is obstructive or central sleep apnea. The differential contribution of central vs. obstructive sleep apnea toward incidental cardiovascular disease in those with significant sleep apnea has not been well studied.
Our group has developed an automated algorithm that deduces on a breath-by-breath level whether reductions in airflow are predominantly due to obstructive or central phenomena. Our algorithm uses several features that are known to be key in distinguishing the type of events and derives a probability of obstruction across each “small” (reduced amplitude) breath. The breath-by-breath probability is then used to determine whether a patient’s burden of sleep apnea is predominantly obstructive or central.
In this work, we analyzed sleep study data from The Osteoporotic Fractures in Men (MrOS) cohort (N=2793) consisting of elderly men, across two visits separated on average by 6.5 years, and derived the probability of obstruction on a breath-by-breath level. The median probability of obstruction for each subject was computed and analyzed against outcomes of cardiovascular disease. We also assessed the stability of the metric in those without any prevalent cardiovascular disease. We find that median probability of obstruction was stable across the two visits, and those with any incident cardiovascular disease had a lower median probability of obstruction: patients with incident cardiovascular outcomes had a significant burden of sleep apnea that was predominantly “central” in nature.

Response: Accurate classification of acute myocardial infarction is instrumental for the appropriate diagnosis and effective management of patients suffering from this widely prevalent cardiovascular condition.
In the past, there have been a variety of clinical scores published to advise clinicians on the best classifications schemes for patients with acute MI. These have included the Thrombolysis in Myocardial Infarction (TIMI) risk score, the HEART score, and the Killip classification. The strength of these traditional scores includes their practicality, as they can be implemented at the bedside to rapidly assist with prognostication. Nonetheless, as technologic advancements have made imaging and tissue identification more accessible, national and international committees are looking to revise traditional classification schemes of acute MI with novel ones leveraging multimodal approaches.

MedicalResearch.com: What is the background for this study? Would you briefly describe the condition of UC?
Response: Lucent 1 and Lucent 2 were the induction and maintenance registration trials studying the efficacy and safety of mirikizumab in patients 18 years and older with moderate to severely active ulcerative colitis. Mirikizumab is a monoclonal antibody targeting the p19 subunit of IL23. Lucent-3 is the open label extension arm for those meeting inclusion criteria after completing Lucent 2. This study evaluated the long term efficacy and safety of mirikizumab in patients with ulcerative colitis who completed a total of 104 weeks of active mirikizumab treatment.
Ulcerative colitis is a chronic incurable inflammatory condition of colon. Common symptoms include diarrhea, blood in the stool, abdominal cramping and bowel urgency. Bowel urgency is one of the most burdensome symptoms that a patient with you could experience.

Response: We generated preliminary data in mice that difelikefalin suppresses itch robustly with very little to no effect on inflammation in a model of atopic dermatitis. This led us to hypothesize that the primary mode of action of difelikefalin must be by direct modulation of sensory neurons to suppress itch and thus would be best suited for a neuropathic itch condition. These are conditions in which itch occurs relatively independently of skin inflammation as in atopic dermatitis due to hyperactive nerves.

MedicalResearch.com: What is the background for this study?
Response: The epidermis is the primary barrier and the first line of defense to combat environmental stressors. The sun's ultraviolet (UV) is one of the main environmental stressors that our body is exposed to daily. UV produces DNA damage in epidermal cells and is a leading cause of skin cancers.
To protect from the damaging effects of UV, epidermal cells become pigmented by melanocytes, pigment-producing cells. Taken up by epidermal cells, the melanin pigment absorbs UV light and reduces DNA damage. How the epidermis senses UV and how it leads to epidermal pigmentation is poorly understood.

Response: Universal screening for SARS-CoV-2 infection on Labor and Delivery (L&D) units is a critical strategy to manage patient and health worker safety, especially in a vulnerable high-prevalence community. We describe the results of a SARS-CoV-2 universal screening program at the L&D Unit at Elmhurst Hospital in Queens, NY, a 545-bed public hospital serving a diverse, largely immigrant and low-income patient population and an epicenter of the global pandemic.
