The reported COVID‐19 cases in the United States of America have crossed over 10 million and a large number of infected cases are undetected whose estimation can be done if country‐wide antibody testing is performed. In this study, we estimate this undetected fraction of the population by a modeling and simulation approach. We employ an epidemic model SIPHERD in which three categories of infection carriers, symptomatic, purely asymptomatic, and exposed are considered with different transmission rates that are taken dependent on the social distancing conditions, and the detection rate of the infected carriers is taken dependent on the tests done per day. The model is first validated for Germany and South Korea and then applied for prediction of the total number of confirmed, active and dead, and daily new positive cases in the United States. Our study predicts the possible outcomes of the infection if social distancing conditions are relaxed or kept stringent. We estimate that around 30.1 million people are already infected, and in the absence of any vaccine, 66.2 million (range: 64.3–68.0) people, or 20% (range: 19.4–20.5) of the population will be infected by mid‐February 21 if social distancing conditions are not made stringent. We find the infection‐to‐fatality ratio to be 0.65% (range: 0.63–0.67). [ABSTRACT FROM AUTHOR]

Chronic kidney disease (CKD) is commonly, if not universally, associated with derangements in bone and mineral metabolism, characterized by hyperphosphatemia, low calcitriol levels, and secondary hyperparathyroidism. The spectrum of these disorders is termed renal osteodystrophy or chronic kidney disease-mineral bone disease complex. Aggressive phosphorus control is the cornerstone of management to prevent debilitating complications. Dietary control, phosphate binders, and administration of active vitamin D analogues is the most common initial therapy. Frequently parathyroidectomy is required to reverse or slow the pathological changes when medical management fails. The most common adverse effect of parathyroidectomy is hypocalcemia. We describe a case report of severe hypocalcemia (secondary to surgical hypoparathyroidism) and “hungry bone syndrome,” treated successfully with teriparatide (Forteo®) in a patient who underwent renal transplantation following subtotal parathyroidectomy.
