Notes

The actual cancer suppressant miR-642a-5p focuses on Wilms Tumour One gene as well as cell-cycle advancement in cancer of prostate.
Precise genomic editing has given rise to treatments in previously untreatable genetic diseases and has led to revolutions in treatment for cancer. In the past decade, the discovery and development of clustered regularly interspaced short palindromic repeats (CRISPR) technologies has led to advances across medicine and biotechnology. Specifically, the CRISPR/Cas9 system has improved translational discovery and therapeutics for oncology across tumor types. In this review, we briefly summarize the history and development of CRISPR, explain CRISPR-Cas systems and CRISPR gene editing tools, highlight the development and application of CRISPR technologies for translational and therapeutic purposes in different oncologic tumors, and review novel treatment paradigms using CRISPR in immuno-oncology, including checkpoint inhibitors and chimeric antigen receptor T cell therapy.
Immune checkpoint inhibitors (ICI) have led to improved survival in patients with a number of different tumor types. The ICI agent nivolumab induces anti-tumor immune responses by inhibiting the programmed cell death 1 protein, but side effects include cardiac immune-related adverse events (irAE) such as myocarditis.¹ The association of nivolumab with atherosclerotic disease has been rarely reported.

A 62-year-old man with metastatic melanoma and recent myocardial infarction (MI) presented with recurrent MI after having undergone several cycles of nivolumab therapy. Repeat cardiac catheterization revealed rapidly progressive in-stent restenosis and diffuse coronary artery disease (CAD) requiring bypass surgery and warranting cessation of nivolumab therapy.

Nivolumab has been linked with dysregulation of immune responses including enhanced T cell activity, which is implicated in CAD. The timing of nivolumab therapy and presentation with non ST elevation myocardial infarction in this patient suggests a serious T cell-driven medication adverse effect. Therefore, close monitoring for atherosclerotic disease progression is warranted in patients on immunotherapy.

Coordination of care between primary care providers and dermatologists is important to ensure high quality and cost efficiency. In our integrated care setting, we used a retrospective cohort study to assess which patients self-refer to dermatology and which returned for a follow-up visit in dermatology.

We identified 107,832 patients with a new rash diagnosis who presented to primary care or dermatology between January and March 2017. We compared patients who self-referred to dermatology with those who used primary care, using multi-level generalized estimating equations with adjustment for patient-level covariables and medical center. We also characterized patients who returned for a follow-up visit in dermatology.

Among patients with a new rash diagnosis, 99% were originally seen in primary care. Patients with a history of a dermatological condition were more likely to present to dermatology. CPI-203 Patients with a history of a dermatological condition or with psoriasis, pigment, hair, bullous, or multiple conditions were more likely to have a follow-up visit with a dermatologist. For each outcome, initial location of care and return for a follow-up visit, we found minimal clustering by medical center or provider.

One percent of patients with a new rash diagnosis self-refer to dermatology in this setting. Patients with a history of a dermatological condition were more likely to self-refer to dermatology and to have a follow-up visit with a dermatologist. Individual dermatologists and primary care providers had little impact on a patient's odds of returning for a follow-up visit.

Peripheral nerve sheath tumors, known as perineuriomas, are typically found on the trunk and extremities. They are less commonly described in the gastrointestinal tract (GI), and extremely rarely are described in the stomach.

We present a case of a 2-cm gastric perineurioma in a 42-year-old patient with nonspecific GI complaints of chronic dyspepsia and epigastric discomfort. Esophagogastroduodenoscopy, followed by endoscopic ultrasound, revealed a 2-cm umbilicated lesion in the stomach, which was subsequently removed with endoscopic submucosal dissection and sent for pathology. Immunohistochemical staining revealed a rare entity known as a gastric perineurioma.

Since the first case of gastric perineurioma was first described in 2004, there have only been 4 reported cases in the English literature. This case highlights the crucial interdisciplinary multidisciplinary effort between pathologists and GI specialists required to reach this diagnosis and showcases endoscopic diagnosis using endoscopic dissection, which allows for complete lesion resection and complete resolution of the patient's symptoms.

International Classification of Diseases-9/10 codes for chronic cough (CC) do not exist, limiting investigation.

To develop a computerized algorithm to determine CC prevalence and its characteristics.

This observational study using administrative data identified hierarchically patients aged 18 to 85 years with CC from 2013 to 2016. First, a specialist-diagnosed CC group was identified using an internal CC encounter code during an outpatient visit to a pulmonologist, allergist, otolaryngologist, or gastroenterologist. Subsequently, an event-diagnosed CC group was identified based on clinical notes through natural language processing, ICD-9/ICD-10 cough codes, and dispensed antitussives.

Prevalence of CC and comparison of clinical characteristics between specialist-diagnosed and event-diagnosed CC subgroups.

A total of 50,163 patients with CC of more than 8 weeks were identified. Of these, 11,290 (22.5%) were specialist diagnosed, and 38,873 (77.5%) were event diagnosed. The CC cohort was 57.4 ± 16.5 years of age; 67.
