3D printed orthoses are custom-made braces and supports designed to stabilize joints and promote healing. By using 3D scanning and additive manufacturing, these devices can be perfectly contoured to a patient's body, offering superior comfort and effectiveness compared to standard off-the-shelf options.

The traditional method of making orthoses involves plaster casting, which is messy and time-consuming. With 3D printing, a clinician simply scans the affected limb, and a digital model is created. This allows for the design of "lattice" structures that are incredibly strong yet lightweight and breathable, preventing the skin irritation and bulkiness associated with traditional plastic or plaster braces.

One of the major advantages of 3D printing is the ability to vary the stiffness of the material within a single device. For example, a wrist brace can be designed to be rigid around the joint for stability but more flexible at the edges to allow for better range…

Syphilis testing remains a vital component of sexual health services, especially given the recent rise in cases in several regions. Early detection is key, as the disease is easily treated with antibiotics in its initial stages. Comprehensive screening programs help to prevent the long-term complications and further transmission.

Testing usually involves a blood test to look for antibodies, which can persist for years after an infection has been treated. In some cases, direct testing of a sore or lesion is performed. Ensuring that testing is accessible and confidential is essential for encouraging high-risk populations to seek help.

If left untreated, syphilis can progress to affect the heart, brain, and nervous system, leading to permanent damage or death. Congenital syphilis, where the infection is passed from mother to baby during pregnancy, is a particularly serious concern that can be prevented through routine screening of expectant mothers.

Modern diagnostic tools are now…
