HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic, progressive neurological disorder and shares many radiological and clinical features with other more prevalent myelopathies. Here, we quantified spinal cord and brain volumes in adults with HAM/TSP in comparison with healthy volunteers (HVs) and individuals diagnosed with relapsing-remitting or progressive multiple sclerosis (RRMS or P-MS). Clinical disability and MRI were assessed in 24 HVs, 43 HAM/TSP subjects, and 46 MS subjects.

Article Synopsis
  • In spring 2018, infrasound sensor arrays in the southeastern US were used to analyze data during a storm front that caused multiple tornado touchdowns, with intensities ranging from EF-0 to EF-2.
  • The sensors managed to accurately determine the locations of the tornadoes, detecting signals from over 100 km away, as well as earlier weaker signals from a convective storm cell that didn't produce tornadoes.
  • The analysis revealed that the main infrasound signals from the tornadoes fell within a frequency range of 2 to 6 Hz, with atmospheric conditions impacting signal detection and requiring advanced signal processing methods to distinguish between multiple storm sources.

Article Synopsis
  • Conjunctivitis can be caused by viruses, bacteria, or allergies, and is very common, especially in primary care settings; there’s no clear way to tell viral from bacterial types just by symptoms.
  • Supportive treatments for viral and allergic conjunctivitis include artificial tears, cold compresses, and antihistamine eye drops, while strict hygiene practices are crucial to prevent spreading the infection.
  • Bacterial conjunctivitis is more frequent in children with distinct symptoms, and while immediate antibiotic prescribing can help, opting for delayed prescriptions can offer similar relief; patients with severe symptoms may need to see a specialist.
