When does life end? New organ donation strategy fuels debate
On a chilly holiday Monday in January 2020, a medical milestone passed largely unnoticed. In a New York City operating room, surgeons gently removed the heart from a 43-year-old man who had died and shuttled it steps away to a patient in desperate need of a new one. More than 3500 people in the United States receive a new heart each year. But this case was different—the first of its kind in the country. “It took us 6 months to prepare,” says Nader Moazami, surgical head of heart transplantation at New York University (NYU) Langone Health, where the operation took place. The run-up included oversight from an ethi...

A one-year longitudinal evaluation of cerebrospinal fluid and blood neurochemical markers in a patient with cryptococcal meningitis complicated by ischemic stroke.
Cryptococcal meningitis (CCM) is caused by the encapsulated basidiomycetous yeast Cryptococcus neoformans and is one of the most common central nervous system (CNS) infections in immunocompromised subjects [1 –4]. In this regard, autoimmune diseases, sarcoidosis, glucocorticoid treatment, solid-organ transplantation, hematologic malignancies, diabetes mellitus, chronic renal failure are well-known predisposing factors for CCM in HIV-negative patients [1–4]. Sources of C. neoformans are excrement of b irds such as pigeons, contaminated soil, and the bark of several tree species [1].

Central Nervous System Opportunistic Infections
Semin Neurol 2019; 39: 383-390 DOI: 10.1055/s-0039-1687842Opportunistic infections of the central nervous system are classically associated with immunosuppression arising from infection with human immunodeficiency virus and with various hematologic malignancies. However, over the past few years, they are increasingly associated with transplantation and various immunosuppressive treatments used to treat autoimmune diseases. They cause significant morbidity and mortality and remain a diagnostic challenge due to the absence of typical signs and symptoms of infection and mimicry by various noninfectious causes. The pathogens a...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Hydroxyurea Therapy Does Not Impact Current Survival Estimates in the East London Sickle Cell Newborn Cohort Study
Conclusions: The study is the first to evaluate survival in a newborn cohort past the age of 20 years. We have confirmed a low mortality rate in childhood, but increased number of deaths in young adults including those with HbSC. This study provides evidence of the benefit of newborn screening and comprehensive care which is accessible at all ages, free of charge. The uptake of HU, particularly at a young age, has been low and a positive effect of HU on survival as described in other studies has not yet been observed in this cohort. Earlier initiation of disease-modifying treatment and longer-term follow-up will be require...

The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2.

Neurological complications in renal transplant patients: A single-center experience
Conclusion We conclude that complications involving the neurological system occur in 10.5% of all transplant patients with 8% involving CNS and 7% involving the PNS. The high mortality rates associated with CNS complications warrant early diagnosis and aggressive treatment in renal transplant recipients.

Middle cerebral artery territory infarct due to Cryptococcus infectionstitle
Cryptococcal meningitis is the most common manifestation of cryptococcosis and is caused by the encapsulated yeast organism Cryptococcus neoformans. It occurs most commonly in patients with impaired cell‐mediated immunity such as in HIV infection; patients with hematological malignancies; patients post solid‐organ transplantation; on chronic steroids or immunosuppressants. Clinically, stroke can arise as a complication of cryptococcal meningitis. While cerebrospinal fluid (CSF) examination is usually not indicated for evaluation of stroke patients, demonstration of cryptococcal yeast forms in CSF is valuable in guiding...
