@sudeshna What the engineering team came up with is a curved shape that allows the bugs to store energy to fuel rapid movements. This allows the robots to function with only a few volts of electricity. The team published results from early tests of their prototype robotic bugs in the journal Advanced Materials Technologies. At this stage, their main success is that they've worked out a way for the cricket-size robots to move with speed and precision using artificial muscle, a technology that typically moves more like a tortoise than a hare. Versatile movements and a lightweight structure should let these robots travel a wide range of terrain, whether it's shifting sand dunes, rocky cliffs, or choppy waters, the engineers say.

RE: Sustained Jawline Definition From Hyaluronic Gel, Study Reports
@sudeshna In this study, 208 patients with severe (74%) or moderate loss of jawline definition were randomized in a 3:1 ratio to receive the filler or serve as controls. The initially untreated controls received the gel after the primary outcome analysis at 6 months. The hyaluronic gel was injected at five sites along the jawline. The mean age of participants was 58 years. The majority were women, and most were White. Dermatologists blinded to treatment compared photos at 6 months relative to those taken at baseline using the photonumeric grading system of 1 to 5. Change in patient satisfaction at 6 months and again at 12 months relative to baseline was also evaluated. From baseline, when 28.9% of participants reported satisfaction on the Global Aesthetic Improvement Scale (GAIS), rates rose to 89.0% at month 6. There was a decline at month 12, but 79.9% remained satisfied after this period of follow-up.
Prognosis of bacterial keratitis
Bacterial keratitis is a serious ocular problem that can, if not appropriately treated, lead to sight-threatening complications such as corneal scarring, perforation, endophthalmitis, and, ultimately, blindness. A particular feature of bacterial keratitis is its rapid progression; corneal destruction may be complete in 24-48 hours with some of the more virulent bacteria. Corneal ulceration, stromal abscess formation, surrounding corneal edema, and anterior segment inflammation are characteristic of this disease.
RE: How to prevent Tick-Borne Diseases?
@sarmistha Prevention strategies for tick-borne diseases can be divided into 3 general categories: environmental, personal, and prophylactic (after a tick bite has occurred). Environmental strategies (eg, control of the population of deer and other vectors and tick control measures) are beyond the scope of this article.
CDC guidelines on the prevention of tickborne diseases are as follows:
Use tick repellents containing DEET, IR3535, picaridin (1-piperidinecaboxylic acid, 2-[2-hydroxyethyl], 1-methlypropyl ester), or other EPA-registered products when outdoors. Follow package label instructions for application.
Wear protective clothing, including long-sleeved shirts, pants, socks, and closed-toe shoes.
Permethrin-treated or impregnated clothing can significantly reduce the number of tick bites when working outdoors.
Protect pets from tick bites by regularly applying veterinarian-approved ectoparasite control products, such as monthly topical acaricide products, acaricidal tick collars, oral acaricidal products, and acaricidal shampoos.
Burnout Rates Rising Among Psychiatrists!
The lingering effects of the COVID-19 pandemic continue to take a toll on the happiness, well-being and lifestyles of many segments of the population, but especially those in the healthcare field, including psychiatrists. The newly released Medscape Cardiologist Lifestyle, Happiness & Burnout Report 2022 explores psychiatrists’ happiness in their personal and professional lives and how they are maintaining mental and physical health. But as the pandemic has worn on, feelings have shifted, and there are clear signs of stress and strain on those in the healthcare field. Now, the percentage of psychiatrists who say they are currently "very" or "somewhat" happy outside of work has fallen to 62%, similar to physicians overall (59%). Female psychiatrists reported being burned out at a greater rate than their male colleagues (46% vs 30%).
Is continuous glucose monitoring (CGM) safe?
Hello, doctor has advised me to get a continuous glucose monitoring (CGM) where a tiny sensor associated with the CGM is inserted under the skin, usually on the belly or arm. It tests glucose frequently in regular intervals (typically 5 to 15 minutes), and a wireless transmitter sends the glucose reading to a display device. Is continuous glucose monitoring (CGM) safe? Please provide some inputs.
Folate deficiency presenting as pyrexia!!
Hello, my 29-year-old caucasian male colleague in USA presented to our medical admissions unit complaining of a 6 week history of dyspnoea on exertion, recurrent fevers and sweats. He had a 7 year history of alcohol excess, drinking 3–4 litres of cider per day. He was a smoker of 10 cigarettes per day, but was otherwise fit and well with no significant past medical or family history. The patient reported no other symptoms and did not take any regular medication. Examination revealed a pulse rate of 124 beats/minute and a blood pressure of 120 mmHg/48 mmHg. He was noted to be febrile with a temperature of 38.8°C. Oxygen saturations were 100% on room air with no signs of respiratory distress. Serum folate levels were found to be low at 1.2 ug/L (normal range 4–24 ug/L) and vitamin B12 levels were low-normal at 202 ng/L (normal range 180–900 ng/L). Iron studies were normal. Initial blood film and subsequent bone marrow examination confirmed a severe megaloblastic picture, consistent with folate deficiency. How to treat folate deficiency?
RE: Dysentery in 2 years old- how to cure?
@srijit Bacillary and amoebic dysentery are both highly infectious and can be passed on if the poo (faeces) of an infected person gets into another person's mouth. This can happen if someone with the infection does not wash their hands after going to the toilet and then touches food, surfaces or another person. If your symptoms are severe or persistent, a physician may prescribe a short course of antibiotics. If you have very severe dysentery, you may need treatment in hospital for a few days.
RE: Cholestatic jaundice- treatment options?
@mainak Management of cholestatic jaundice widely depends upon underlying etiology and type of cholestasis. Usually, the mainstay of obstructive cholestasis is biliary decompression. Management of hepatocellular cholestasis includes symptomatic treatment of associated symptoms while specific treatment for the underlying disease process is attempted. In common bile duct stones, endoscopic sphincterotomy with or without stent placement can relieve the obstruction. Similarly, in benign CBD strictures, stricture dilation and stent placement can relieve the obstruction.
In malignant obstruction, depending upon the stage of disease and the operative candidacy of the patient, surgical resection of the obstructive lesion is preferred. If complete resection is not possible, surgical hepaticojejunostomy and the Roux-en-Y bypass is an option. If a patient is not a surgical candidate, either palliative CBD stent is placed endoscopically (usually metal stent). If endoscopic stent placement is not successful, a percutaneous transhepatic cholangiography tube can be placed for biliary decompression. Antibiotics are considered in pre and post biliary decompression phase to reduce the risk of sepsis.
RE: Iron deficiency anemia- how to recover?
@deepan Your doctor may recommend over-the-counter iron tablets to replenish the iron stores in your body. Your doctor will let you know the correct dose for you. Iron is also available in liquid form for infants and children. To improve the chances that your body will absorb the iron in the tablets, you may be instructed to: Take iron tablets on an empty stomach. If possible, take your iron tablets when your stomach is empty. However, because iron tablets can upset your stomach, you may need to take your iron tablets with meals.
Don't take iron with antacids. Medications that immediately relieve heartburn symptoms can interfere with the absorption of iron. Take iron two hours before or four hours after you take antacids.
Take iron tablets with vitamin C. Vitamin C improves the absorption of iron. Your doctor might recommend taking your iron tablets with a glass of orange juice or with a vitamin C supplement.
