Tetanus is a vaccine-preventable disease that commonly occurs in under-resourced countries; clinically, it manifests as spontaneous muscle spasms and overall body rigidity, which can lead to autonomic dysfunction. The diagnosis of tetanus is primarily clinical, although laboratory testing is available, treatment of a clinical case should never be delayed. Management includes general support measures, prevention of complications, control of muscle spasms, and immunoglobulin.

Increased gas adsorption in a series of post-synthetically modified metal-organic frameworks (MOFs) of the type HKUST-1 was achieved by the partial cation exchange process. Manipulation of post-synthetic conditions demonstrates high tunability in the site substitution and gas adsorption properties during the dynamic equilibrium process. In this work, post-synthetic modification of Cu(BTC) is carried on by exposure to TM solutions (TM = Mn, Fe, Co, Ni) at different time intervals.

Although alcohol and nicotine are often used together, the biological consequences of these substances are not well understood. Identifying shared targets will inform cessation pharmacotherapies and provide a deeper understanding of how co-use of alcohol and nicotine impacts health, including biomarkers of stress and inflammation. We examined the effects of nicotine exposure and withdrawal on alcohol self-administration (SA), stress and inflammatory biomarkers, and a G-protein coupled receptor subunit (Gβ) in brain areas associated with drug use.

A horseshoe kidney (HSK) is a urological malformation that is typically found incidentally after a traumatic injury due to its asymptomatic nature. We present a 25-year-old male with multiorgan injuries secondary to blunt abdominal trauma caused by a gunshot wound. We report the courses of action taken that led to the identification of the HSK and other associated intra-abdominal injuries and the subsequent surgical management.
