Compressive Strength of Newly Developed Nonsintered Hydroxyapatite Blocks for Bone Graft Applications.

Objective:  This study aimed to fabricate and evaluate the phase purity and compressive strength of the nonsintered hydroxyapatite (HA) block obtained via phase transformation of set calcium sulfate dihydrate (CSD) block under hydrothermal conditions at different temperatures.

Materials And Methods:  Nonsintered HA block was prepared by immersion CSD block (4 mm in diameter and 8 mm in height) in a 1 mol/L sodium phosphate (NaPO) solution under hydrothermal conditions at 100°C, 140°C, and 180°C for 48 hours. X-ray diffraction was used to determine the crystalline phase of the obtained blocks.

Effect of hydrothermal treatment of titanium in high concentration of AgNO solution on surface morphology and roughness.

Development of silver (Ag) modified titanium (Ti) as an antibacterial dental implant has recently been growing. Ag demonstrated an excellent antibacterial property without the risk of bacterial resistance. Hydrothermal treatment using AgNO solution is one of the facile and promising methods to modify Ti surface with Ag.

Happy hypoxia in critical COVID-19 patient: A case report in Tangerang, Indonesia.

Coronavirus Disease 2019 (COVID-19) is a public health emergency of international concern with increasing cases globally, including in Indonesia. COVID-19 clinical manifestations ranging from asymptomatic, acute respiratory illness, respiratory failure that necessitate mechanical ventilation and support in an intensive care unit (ICU), to multiple organ dysfunction syndromes. Some patients might present with happy hypoxia, a condition where patients have low oxygen saturations (S  < 90%), but are not in significant respiratory distress and often appear clinically well, which is confusing for the doctors and treatment strategies.
