Response: The research I presented on details a randomized, prospective study done to evaluate whether it would be feasible and effective to implement a yoga program for breast cancer patients receiving chemotherapy that could reduce patients' chemotherapy-related symptoms and improve their quality of life.
50 patients were recruited, half of whom underwent a 12-week long yoga program with weekly courses, while the other half did not participate in the program.
Surveys were completed at baseline, 6 weeks, and 12 weeks assessing patients' functional wellbeing, sleep quality, and anxiety/depression levels.

Response: In recently published meta-analyses, focusing on the general population, showed that both overt hypothyroidism and subclinical hypothyroidism were linked to higher all-cause and cardiovascular mortality. However, there is still debate and conflicting evidence on managing overt and subclinical hypothyroidism in the elderly.
This study aimed to evaluate and confirm the association between hypothyroidism and mortality in the elderly population.

Response: Nailfold capillaroscopy (NFC), long used in rheumatology is a new approach to investigation of glaucoma.
Posterior to the nailbed and just anterior to the proximal nailfold is the cuticle, which has no structural elements visible to the naked eye. NFC is a non-invasive imaging modality that provides a highly magnified view of the capillaries at the nailfold of digits. It has also been used in ophthalmology to show morphological changes at the nailfold capillaries of POAG and XFG/XFS patients, helping to confirm the systemic nature of these diseases.

Nailfold Capillaroscopy / Dr. Ritch[/caption]
With nailfold capillaroscopy, an extensive array of capillaries can be seen greatly enlarged on a monitor screen. Capillary loops can be imaged, stored, recorded with videoscopy, and blood flow actively imaged and measured..
The first series of papers on glaucoma were written by Prof Josef Flammer’s group at the turn of the 21st century, looking at vasospasm, blood flow in normal-tension and high-tension glaucoma, and relating ocular blood flow alterations to systemic vascular regulation and relating laser Doppler flowmetry to NFC.
Studies from Korea later associated nailbed hemorrhages and loss of nailbed capillaries to the presence of optic disc hemorrhages and investigated correlation of of heart rate variability with visual field defects and nailfold capillaroscopy.
Studies by our group began with the publication in 2015 of a paper by Pasquale et al (Nailfold Capillary Abnormalities in Primary Open-Angle Glaucoma: A Multisite Study. IOVS;56:7021) using NFC video microscopy, associating dilated capillaries, avascular zones, and hemorrhages with primary open-angle glaucoma. Successive manuscripts and presentations at conferences have indicated differences between capillary loop patterns in high-tension and normal-tension POAG and exfoliation syndrome/exfoliation glaucoma.
Our goal in this paper was to compare nailfold peripheral blood flow in XFG, which had not previously been compared to control subjects using NFC. We explored the peripheral blood flow at the nailfold of patients with high-tension glaucoma, normal-tension glaucoma, exfoliation glaucoma (XFG) and compared it to control subjects further evaluate the possible differences between these glaucoma entities. We examined the morphology and extent of nailfold capillary loops, vascular tortuosity, blood flow, and nailfold hemorrhages.

Response: The Oncotype DX Breast Cancer Assay was developed to genetically profile patients with early stage, hormone positive breast cancer and predict their 10-year risk of distant recurrence. A high-risk recurrence score is associated with a benefit from adjuvant chemotherapy whereas a low risk recurrence score is associated with little to no benefit.
BRCA mutated tumors have been associated with higher risk recurrence scores as compared to BRCA negative breast cancer patients. However, there have been minimal studies relating discordance to BRCA mutations. Discordance refers to a poorly differentiated or high-grade tumor with a low risk recurrence score. Prior studies demonstrated 7-19% discordance, or difference between recurrence score and tumor grade in breast cancer patients regardless of BRCA mutation status.
It has been concluded that patients who exhibit discordance may benefit from additional therapy in conjunction with endocrine therapy.

Response: Very few studies have examined the association between frozen embryo transfer and the risk of childhood cancer and most of them have been too small to show any effects.
In our large nationwide population based study we found that frozen embryo replacement was associated with an increased risk of childhood cancer and especially for leukemia and neuroblastomas.

Response: HIV pre-exposure prophylaxis (PrEP) is being rolled out globally. This will protect many people from HIV, however PrEP does not protect against other sexually transmitted infections (STI). So we wanted to quantify how much STIs are in PrEP users as a means to advocate to strengthen sexual health services in these settings where PrEP is being offered.

Response: Deletions on chromosome 2p16.3, involving deletion of the NEUREXIN1 gene, dramatically increase the risk of developing a wide range of neurodevelopmental disorders including autism, Tourette’s syndrome and schizophrenia. We don’t fully understand the mechanisms involved. In our study we wanted to understand how the genetic deletion impacts on brain function and the ability of brain regions to communicate with one another, as these are known to be impaired in these neurodevelopmental disorders. We also wanted to determine how the genetic deletion impacts on the function of neurotransmitter systems involved in these disorders, and whether drugs targeting these neurotransmitter systems could restore some of the deficits in brain function seen.

Response: Approximately one-third of patients with intractable status epilepticus do not respond to benzodiazepines, often the first line medications given in the emergency department, leaving doctors to decide among three commonly prescribed anti-convulsants.
In this study all of the anti-convulsants were equally effective.
The trial gives doctors a way to clear the air of arguments that one of these drugs works any better than the others, or that any one of them is a lot safer. It gives doctors a reason to choose a dosing strategy in status epilepticus for levetiracetam, which has otherwise been controversial and non-standard.

Response: Our work focuses on elucidating the mechanisms that drive the pathogenesis and progression of myeloproliferative neoplasms (MPN). Dysregulation of the TP53 pathway is associated with MPN progression evidenced by the association of TP53 loss of heterozygosity with transformation to acute myeloid leukemia (AML) and the presence of inactivating mutations of TP53 found in a proportion of MPN-related AML patients. Studies have shown that TP53 mutations, TP53 deletions and overexpression of the negative regulator of TP53, Murine Double Minute 2 (MDM2) all contribute to TP53 downregulation in MPNs and we therefore are interested in exploring other potential means by which TP53 is downregulated. Protein Phosphatase, Mg2+/Mn2+
Dependent 1D (PPM1D) is another negative regulator of the TP53 pathway and activating mutations in this gene are present in myeloid malignancies including MPNS. We therefore hypothesized that genomic alterations in PPM1D and/or overexpression of PPM1D would be found in the hematopoietic cells of MPN patients.

Response: Triple-negative breast cancer (TNBC), a subtype of breast cancer that lacks estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2), represents 12-20% of all breast cancers. TNBC has poor prognosis, high recurrence, a low survival rate, and has higher incidence in African-American and Hispanic women. Currently, there are no effective therapies for treating a substantial portion of TNBC patients.
Enhancer of zeste homolog 2 (EZH2) is the main enzymatic subunit of the polycomb repressive complex 2 (PRC2) which catalyzes trimethylation of histone H3 lysine 27 (H3K27me3) to promote transcriptional silencing. EZH2 is overexpressed in multiple types of cancer including triple negative breast cancer (TNBC) and high expression levels correlate with poor prognosis. Several EZH2 inhibitors which inhibit the enzymatic activity of EZH2 have shown promise in treating sarcoma and follicular lymphoma in clinics. However, current EZH2 inhibitors are ineffective at blocking proliferation of TNBC cells even though they effectively inhibit the enzymatic activity of EZH2. While the proteolysis targeting chimera (PROTAC) technology for selective degradation of the target protein has been rapidly gaining momentum in the drug discovery field, the hydrophobic tagging approach for selective protein degradation has received considerately less attention from the scientific community.

Response: Relapsed or refractory Peripheral T-Cell Lymphoma (R/R PTCL) remains a disease of significant unmet medical need.
Duvelisib is an oral dual inhibitor of PI3K-δ and PI3K-γ approved for the treatment of adult patients with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) after at least two prior therapies, relapsed or refractory follicular lymphoma (FL) after at least two prior systemic therapies, and is being developed for the treatment of additional hematologic malignancies including R/R PTCL.
In early studies, we saw a suggestion of quite good activity of duvelisib as a single agent in a range of subtypes of T-cell lymphoma.
The PRIMO study is an ongoing, multi-center, open-label, registration-directed Phase 2 study evaluating duvelisib in patients with R/R PTCL that is expected to enroll approximately 120 patients. The study includes both a dose optimization phase and an expansion phase.
The Primo study will be sufficiently powered to give a much more precise estimate of the activity in peripheral t cell lymphomas. However, prior to initiating the main cohort we needed to first try to identify an optimal dose. That “dose optimization cohort” is the subject of our presentation here.

Response: The rate of rural hospital closures has been increasing over the last ten years. Rural hospitals close for a number of reasons including poor hospital economic health tied to uncompensated care and community factors, like a local aging population.
Rural hospital and unit closures have been tied to decreased access to emergency and specialty care for patients including decreased access to obstetric-gynecological services and increase travel time for appointments. A recent paper also found a 6% increase in mortality in conditions needing emergent attention after rural hospital closures. We examined the impact of hospital closures in rural counties on the counties’ supply of physicians.

Response: Opioid reuse and relapse are common outcomes even when a person is seeking treatment for their addiction. These reuse events pose many health risks, as well as risk for treatment failure. We currently lack the much needed tools to understand and predict this reuse vulnerability.
In this study, we used computer games that assess a person's decision making process, to get at psychological processes related to how people make decisions involving risks, when they transitioned between lower and higher reuse vulnerability states during the first few months of opioid treatment.

Response: One of the most common questions we get from parents with a child with autism is, "what is the likelihood of having a second or third child with autism, and what is the chance others in our family will have kids with autism?".
To help provide answers to these questions, we started the infant (or baby) siblings study ten years ago. Families having an older sibling with a diagnosis of autism were invited to enroll their next born for assessment and following to see if they also developed autism, and what the likelihood of that happening was. Biological samples like blood, and DNA from blood, were also collected and tested.

Response: Graft-versus-host disease (GVHD) is the leading cause of non-relapse mortality (NRM) after allogeneic hematopoietic cell transplantation (HCT). Acute GVHD occurs in approximately 50% of HCT patients and targets the skin, liver, and gastrointestinal tract primarily. The change in clinical symptoms (e.g. reduction in volume of diarrhea) is used as the primary endpoint in most trials of acute GVHD treatment, but more accurate metrics are needed to predict long-term survival.
Over the past decade, the Mount Sinai Acute GVHD International Consortium (MAGIC) has studied two biomarkers important in GVHD pathogenesis: suppressor of tumorigenesis 2 (ST2) and regenerating islet-derived 3 alpha (REG3). These proteins are shed into the bloodstream when the gastrointestinal tract is damaged during GVHD, the most lethal form of acute GVHD. The concentrations of ST2 and REG3 can be used generate an individual’s estimated probability of 6 month NRM known as the MAGIC Algorithm Probability (MAP).
Our study evaluated whether the MAP measured at the start of GVHD treatment and four weeks later could predict long-term survival and we compared the MAP to clinical response after four weeks, the gold standard of response.

Response: We found that many children who were planning to travel internationally were eligible for MMR vaccination prior to departure but often did not receive it - especially if they were aged 6 months to 6 years. That is because most children do not routinely receive their first dose of MMR till 12-15 months of age and their second dose of MMR till 4-6 years of age. However, ACIP recommendations are different for children who are traveling internationally. The risk of being infected with measles is much higher outside of the US, so it is recommended that children older than 1 year have had 2 MMR vaccinations and that children 6-12 months receive 1 MMR vaccination prior to travel. MMR vaccination is a safe and effective way to greatly reduce the risk of measles infection.

Response: The Phase 2 CAPTIVATE (PCYC-1142) clinical trial evaluated 164 patients younger than 70 years (median age of 58 years) with previously untreated CLL/SLL. Patients were planned to receive ibrutinib for 3 cycles, followed by 12 cycles of ibrutinib and venetoclax in combination. Ninety percent of patients was able to complete the planned therapy. MRD status was evaluated in PB after 6, 9, and 12 cycles and in BM after 12 cycles of the combination.

Response: Professional societies and government agencies have variable recommendations regarding how often women should get a screening mammogram. Breast cancer screening may be recommended annually or biennially. These differing recommendations lead to confusion for both referring physicians and patients.
The goal of our study was to better understand differences between annual and biennial screening. We reviewed clinical outcomes of women undergoing annual or biennial mammographic screening to determine if there is an advantage to annual screening.

Response: The background, or what prompted this study, is that research on this topic is pertinent right now as more states continue down a path towards legalization. A large share of the research base and public debate centers around the potential adverse effects of marijuana accessibility, consumer-based concerns, and health specific outcomes associated with usage.
This research instead focuses on a lesser explored question related to the potential for the physical dispensary locations to impact crime levels, which is also an important consideration when assessing the impact of recreational marijuana legalization.

Response: Opioid use in pregnancy is a major public health crisis. Opioids adversely impact maternal, fetal and infant health. Infants who were exposed to opioids in the womb, can have withdrawal symptoms soon after birth, and are also at risk for poor long term neurodevelopment outcomes.
Our group studied the changes in brain function in infants exposed to opioids in the womb, to understand how opioids affect the developing brain. We used resting state functional MRI to study these infants.

Response: Chronic hepatitis C (HCV) infection affects millions of persons in the United States but especially minorities and persons from low income communities. Current national guidelines recommend testing all baby boomers (born 1945 – 65) for HCV with the aim of ultimately curing those with chronic HCV infection with a short course of highly effective medication. However implementation of these guidelines faces many hurdles in “safety net” practices serving vulnerable populations.
