Brain Blood Flow Measured With Light, New Technology

Biomedical engineers at the University of California, Davis, have developed a new technique for measuring blood flow in the human brain, which could be used in patients with stroke or traumatic brain injury, for example.

The new technique, based on conventional digital camera technology, could be significantly cheaper and more robust than prior methods. The work is described in a paper published in the journal Optica.

Evaluating The Efficacy Of Anterior Segment SS-OCT For Extraoscular Muscle Thickness

A study evaluated the usefulness of anterior segment SS-OCT in measuring horizontal extraocular muscle thickness, distance from the corneal limbus to the insertion of horizontal extraocular muscle (limbus to insertion distance, LTID) and scleral thickness in Korean pediatric strabismus patients. To evaluate the efficacy of anterior segment swept-source optical coherence tomography (SS-OCT) for examining horizontal extraocular muscle thickness, distance from the corneal limbus to the insertion of the horizontal extraocular muscle.

Astronauts Body Temperature Is Increased During Long-duration Space Missions

Humans’ core body temperature (CBT) is strictly controlled within a narrow range. Various studies dealt with the impact of physical activity, clothing, and environmental factors on CBT regulation under terrestrial conditions. However, the effects of weightlessness on human thermoregulation are not well understood. Specifically, studies, investigating the effects of long-duration spaceflight on CBT at rest and during exercise are lacking.

Teleradiology: Feasibility in Nepal

Teleradiology has been proposed as a way to make radiological services available in rural areas especially where the radiologists are separated from the major population. It involves the electronic transmission of non-invasive radiographic images such as digitized X-ray, ultrasound, CT scan, and MRI, nuclear medicine as well as consultative text from one geographical location to another for the purpose of interpretation, consultation, diagnosis, and treatment. 

Postoperative Pulmonary Complications after VATS Lobectomy and Risk Factors

The effect of VATS lobectomy in comparison to thoracotomy in reducing hospital LOS and postoperative pain is well established. It is also becoming increasingly evident that a VATS approach may reduce incidence of PPC, however, developing a PPC is still likely in patients undergoing VATS lobectomy, and PPC frequency needs confirmation, as well as identifying the effect of developing a PPC on short-term outcomes.

Evaluating The Effects Of Two Low-Doses Of Dexamethasone On Blood Glucose Concentrations Among Patients

A prospective study includes the impact of a low dose of Dexamethasone, is a potent corticosteroid when administered alone or in combination alone has proven efficacious in preventing nausea and vomiting (PONV) perioperatively. However, the administration of even a single dose has been associated with hyperglycemia. This is the first study that evaluates the effect of two low-doses of dexamethasone (4 and 8 mg) on blood glucose concentrations among diabetics and nondiabetics in patients who have received spinal anaesthesia.
