The Biomarker Disruptor

Would you rather get a biopsy or a blood test to check for prostate cancer? Quanterix chairman/CEO Kevin Hrusovsky said with the help of his company's latest product, the SR-X Ultra-Sensitive Biomarker Detection System, a simple blood test could replace, or complement, invasive diagnostic procedures. Using digital technology, the SR-X can detect cancer, neurological disorders, inflammatory and infectious diseases, and heart events months or even years earlier, and less invasively, than existing technology.   Using Quanterix's single molecule array (Simoa) science, which is similar to a digital enzyme-linked immunosorbent assay (ELISA), the SR-X measures six biomarkers simultaneously with a roughly 1,000-fold improvement in sensitivity. This precision allows researchers to see proteins at a level not seen before; thus, detecting diseases when they're more easily treatable. As it builds its diagnostics division, Quanterix—which closed its IPO in December 2017—is putting its attention on two lower-risk areas: research, to discover and validate new biomarkers; and pharmaceuticals, where the company already has a strong foothold. During the 2018 JP Morgan Healthcare Conference in San Francisco, Hrusovsky said 23 of the top 25 pharmaceutical companies use Quanterix's technology. "There are ways to use biomarkers to make drugs less toxic and more effective by lowering the dose and making them more personalized," he explained in an interview. It's a worthwh...

Antiphospholipid Syndrome (APS) important in vascular medicine as well as obstetrics. In obstetrics, it is important because it can cause fetal loss, intrauterine growth retardation and severe preeclampsia. In vascular medicine it is important because it can cause thrombotic events which could be arterial, venous or microvascular [1]. It can also be accompanied by moderate thrombocytopenia [2]. Thrombotic events involving multiple organs may be termed catastrophic Antiphospholipid Syndrome [3]. APS is an autoimmune disease with antibodies directed against beta2 glycoprotein I. This leads to suppression of tissue fact...

It is needless to say that heart disease in pregnancy is a challenge for the obstetrician and the cardiologist. Hemodynamic changes in pregnancy and labour can adversely affect many of the significant cardiac lesions. Increase in blood volume and heart rate are the important factors during pregnancy. In general stenotic lesions and pulmonary hypertension are poorly tolerated, while regurgitant lesions are better tolerated. Specific risks like aortic dissection and rupture are there for coarctation of aorta. Several risk stratification schemes have been developed for assessing the risk of pregnancy with heart disease over ...

Authors: Pek WS, Tan BK, Ru Ng YY, Kiak Mien Tan V, Rasheed MZ, Kiat Tee Tan B, Ong KW, Ong YS Abstract BACKGROUND: Nipple-sparing mastectomies (NSMs) are increasingly performed to obtain the best aesthetic and psychological outcomes in breast cancer treatment. However, merely preserving the nipple-areolar complex (NAC) does not guarantee a good outcome. Darkly pigmented NACs and a tendency for poor scarring outcomes are particular challenges when treating Asian patients. Herein, we review the reconstructive outcomes following NSM at Singapore General Hospital. METHODS: All breasts reconstructed following NSM o...

In this report, we describe a patient who visited the emergency department with a large swelling in his right cheek. A blood test and computed tomography revealed odontogenic maxillary sinusitis. The patient developed sepsis due to a progressive multifocal abscess. An abscess was seen in the temporal muscle, infratemporal fossa, and interorbital region. To control this multifocal abscess, we used the facial dismasking flap (FDF) approach. After debridement using the FDF approach, we succeeded in obtaining sufficient drainage of the abscess, and the patient recovered from sepsis. The advantages of the FDF approach are that ...

This study aimed to investigate trends in mastectomy and breast reconstruction over the past 10 years and to evaluate the impact of NHIS coverage on breast reconstruction. METHODS: Nationwide data regarding mastectomy and breast reconstruction were collected from the Korean Breast Cancer Society registry database. Multiple variables were analyzed in the records of patients who underwent breast reconstruction from January 2005 to March 2017 at a single institution. RESULTS: At Seoul National University Hospital, the total number of reconstruction cases increased 13-fold from 2005 to 2016. The proportion of immediate...

Authors: Kwak MD, Machens HG Abstract Chronic lymphedema is caused by an impairment of the lymphatic system due to primary or secondary causes. Vascularized lymph node transplantation (VLNT) is currently the most promising and frequently used technique besides lymphaticovenous anastomosis. However, the vessel anatomy in the lateral thoracic region is sometimes quite variable. Based on our experiences with vascular anatomical inconstancy in the lateral thoracic region, we planned a lateral intercostal artery perforator flap for VLNT in a female patient with chronic stage II lymphedema of both legs after cervical can...

This study builds on preliminary findings from the first phase of the INTERSTROKE study, which identified ten modifiable risk factors for stroke in 6,000 participants from 22 countries. The full-scale INTERSTROKE study included an additional 20,000 individuals from 32 countries in Europe, Asia, America, Africa and Australia, and sought to identify the main causes of stroke in diverse populations, young and old, men and women, and within subtypes of stroke. To estimate the proportion of strokes caused by specific risk factors, the investigators calculated the population attributable risk for each factor (PAR; an esti...
