Divergence of Drosophila species: Longevity and reproduction under different nutrient balances.

How nutrition impacts growth, reproduction and longevity is complex because relationships between these life events are difficult to disentangle. As a first step in sorting out these processes, we carried out a comparative analysis of related species of Drosophila with distinct feeding habits. In particular, we examined life spans and egg laying of two generalists and three specialists on diets with distinct protein-to-carbohydrate ratios.

UTIs in patients with neurogenic bladder.

Urinary tract infections (UTI) remain one of the most prevalent and frustrating morbidities for neurogenic bladder patients, and death attributed to urosepsis in the spinal cord injury (SCI) patient is higher when compared to the general population. Risk factors include urinary stasis, high bladder pressures, bladder stones, and catheter use. While classic symptoms of UTI include dysuria, increased frequency and urgency, neurogenic bladder patients present differently with increased spasticity, autonomic dysreflexia, urinary incontinence, and vague pains.

Prostate cancer and the increasing role of active surveillance.

Prostate cancer (PC) is the most often diagnosed non-skin cancer and the second leading cause of cancer-related death among men in the United States. As a result, for many years the American Urological Association (AUA) and the American Cancer Society have issued statements recommending screening for PC, resulting in its widespread implementation in the United States. Recently, the United States Preventative Services Task Force gave PC screening a recommendation of D, that is, against PC screening for all men.

Multiple liver amoebic abscesses detected on FDG PET/CT.

We report a case of liver amoebic abscesses in a 58-year-old man referred for a FDG PET/CT with an initial diagnosis of secondary hepatic lesions. This patient, coming from Sri Lanka, presented with fever and shivers, pain in the right flank, vomiting, and diarrhea for a month. The FDG PET/CT showed a hepatic heterogeneous uptake with multiple cold lesions surrounded by a faint hypermetabolism.
