Deep-learning Based Location of Spine CT

CT-guided epidural steroid injection (ESI) thrives among interventional radiologists. Although X-ray fluoroscopy still remains as the gold standard to guide ESI, CT guidance has the merits of accurate location of needle tip and relatively low radiation doses with intermittent mode. However, it is time-consuming for doctors to select the optimal plane for needle placement and manually segment spinal structures. The main of the study is to automatically identify the optimal plane...

Artificial Intelligence Identifying Polyps in Real-world Colonoscopy

Recently, artificial intelligence (AI) assisted image recognition has made remarkable breakthroughs in various medical fields with the developing of deep learning and conventional neural networks (CNNs). However, all current AI assisted-diagnosis systems (ADSs) were established and validated on endoscopic images or selected videos, while its actual assisted-diagnosis performance in real-world colonoscopy is up to now unknown. Therefore, we validated the performance of an ADS in...

Estimation of CPR Chest Compression Depth

Optimal chest compression depth during CPR is 4.56cm which is at variance with the current guidelines of 5.0-6.0cm. A change in guidelines is only worthwhile if healthcare professionals can accurately judge a subtle reduction in chest compression depth during CPR by a relatively small amount.

Assessment of Renal Physiology by Magnetic Resonance Imaging (MRI) in Normal Volunteers

Estimation of Glomerular Filtration Rate (GFR) is the primary test used to assess patients with renal disease. Although serum creatinine based GFR and nuclear medicine based estimations are routinely used in clinical practice, GFR estimation by Inulin is the recommended gold standard. Inulin based estimation of GFR is cumbersome and time consuming. A decrease in blood flow to the kidney (Renal Blood Flow (RBF)) is known to cause a decrease in GFR. RBF is typically determined ...

mHealth-Assisted Conditional Cash Transfers to Improve Timeliness of Vaccinations

Vaccination is a cost-effective strategy for conferring immunity against a host of preventable diseases, however, rates of timely childhood vaccinations remain inadequate in resource-limited settings. We propose to evaluate the feasibility and efficacy of mHealth-assisted conditional cash transfers as a means of overcoming individual barriers to timely vaccinations. The study will form the basis for a pragmatic randomized controlled trial of the efficacy and cost-effectiveness ...

Umbilical Venous Catheter Insertion Depth in Neonates

In this randomized clinical study, neonates who require umbilical venous catheter (UVC) insertion as part of their routine care at anytime during their NICU admission will be randomized to one of the 2 formulas for estimation of the pre-insertion UVC depth (umbilicus to the nipple in cm minus 1 (UN - 1) or birth weight based formula ([(3× birth weight (Kg) + 9)/2+1)]. UVC will be inserted under sterile condition as per unit protocol. To verify the UVC tip position, a thoracoab...

Application of Deep-learning and Ultrasound Elastography in Opportunistic Screening of Breast Cancer

As the most common cancer expected to occur all over the world, breast cancer still faces with the unsatisfied diagnostic accuracy in US imaging. S-detect is a sophisticated CAD system for breast US imaging based on deep learning algorithms.

Non-inferiority Trial of Conditional vs Universal Follow up for Children With Fever in Democratic Republic of Congo

Providers in integrated Community Case Management (iCCM) programs in low resource settings often see children without any danger signs, presenting with fever but not having pneumonia, malaria, or diarrhea. These children are sent home (often with analgesic only), and caretakers are advised to return in 2 or 3 days. In this study, we are evaluating if conditional return advice (i.e. return in 2 or 3 day only if your child is still sick") results in the same proportion of childre...
