Exposure of bone to ionizing radiation, as occurs during radiotherapy for some localized malignancies and blood or bone marrow cancers, as well as during space travel, incites dose-dependent bone morbidity and increased fracture risk. Rapid trabecular and endosteal bone loss reflects acutely increased osteoclastic resorption as well as decreased bone formation due to depletion of osteoprogenitors. Because of this dysregulation of bone turnover, bone's capacity to respond to a mechanical loading stimulus in the aftermath of irradiation is unknown...

Obesity is a risk factor for a plethora of severe morbidities and premature death. Most supporting evidence comes from observational studies that are prone to chance, bias and confounding. Even data on the protective effects of weight loss from randomized controlled trials will be susceptible to confounding and bias if treatment assignment cannot be masked, which is usually the case with lifestyle and surgical interventions. Thus, whilst obesity is widely considered the major modifiable risk factor for many chronic diseases, its causes and consequences are often difficult to determine...

OBJECTIVE: To study the therapeutic efficacy of an oral iron retard preparation in patients with iron deficiency anemia. METHODS: In an investigator-initiated open study, 28 patients with iron deficiency anemia were treated with an iron sulfate sustained-release preparation (80 mg iron ions per tablet). The bioavailability was determined from the increase in the haemoglobin value under therapy and the measured blood loss. For the quantification of individual blood losses, a (59)Fe labeling method was used and the (59)Fe whole body retention in the observation period was measured with a whole body counter...

Distal nephron acid secretion is mediated by highly specialized type A intercalated cells (A-ICs), which contain vacuolar H(+)-ATPase (V-type ATPase)-rich vesicles that fuse with the apical plasma membrane on demand. Intracellular bicarbonate generated by luminal H(+) secretion is removed by the basolateral anion-exchanger AE1. Chronically reduced renal acid excretion in distal renal tubular acidosis (dRTA) may lead to nephrocalcinosis and renal failure. Studies in MDCK monolayers led to the proposal of a dominant-negative trafficking mechanism to explain AE1-associated dominant dRTA...

INTRODUCTION: Lymph node dissection (LND) performed during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) remains controversial and difficult to evaluate. The aim of this study was to investigate whether removal of more lymph nodes during RNU is safe and improves oncologic outcomes. METHODS: We evaluated 422 patients who underwent RNU with concomitant LND for upper tract urothelial carcinoma between 1976 and 2015, assessing for an association between total nodes removed, recurrence-free survival, and cancer-specific survival using Cox proportional hazards models...

BACKGROUND AND PURPOSE: Small infants with biliary atresia and hypoplastic portal veins (PV) are at risk for portal vein thrombosis (PVT) after liver transplantation (LT), which can lead to graft loss and mortality. Extra-anatomical PV reconstruction techniques have been established for adult cases of PVT; however, they have not been widely accepted for infants. METHODS: Here, we report the successful use of an extra-anatomical meso-portal venous jump graft to treat early PVT after LT in a 6-month-old infant with biliary atresia and PV hypoplasia...

BACKGROUND: Spindle cell lipoma is an uncommon variant of lipoma and usually occurs as a solitary, subcutaneous, and well circumscribed lesion in the posterior neck, shoulders, and back of older men. Primary renal lipomas are rarely reported. Spindle cell lipoma in the kidney has not been previously described in the literature. CASE REPORT: A 60-year-old Chinese man suffered graft failure 10 years after living related donor kidney transplantation. During cancer surveillance, he was found to have a mass in the renal allograft, which increased in size and was suspicious for renal cell carcinoma on computerized tomographic scan...

BACKGROUND: Antibody-mediated response in solid organ transplantation is critical for graft dysfunction and loss. The use of immunosuppressive agents partially inhibits the B-lymphocyte response leading to a risk of acute and chronic antibody-mediated rejection. This study evaluated the impact of JAK3 and PKC inhibitors tofacitinib (Tofa) and sotrastaurin (STN), respectively, on B-cell proliferation, apoptosis, and activation in vitro. METHODS: Human B cells isolated from peripheral blood of healthy volunteers were cocultured with CD40 ligand-transfected fibroblasts as feeder cells in the presence of interleukin (IL) 2, IL-10, and IL-21...

INTRODUCTION: Along with death engraftment, in recent years, antibody-mediated damage has been identified as the leading cause of loss of kidney transplants. Despite the recognition of the role of the B-lymphocyte subpopulation in the development of both tolerance and rejection, little is known about the trigger mechanisms and effectors of this humoral response. BACKGROUND: We analyzed the relationship between B lymphocyte subpopulations and levels of B-cell-activating factor (BAFF) with the histological findings in biopsies of renal transplantation...

PURPOSE: Iatrogenic noise produced by mastoid or craniotomy drills may cause hearing damage, which is induced by the generation of reactive oxygen species (ROS) and the reduction of cochlear blood flow (CoBF). This study investigated whether propofol could reduce noise-induced hearing loss (NIHL) in a guinea pig model. METHODS: Sixty-four male pigmented guinea pigs were randomly and equally divided into 4 groups: control, noise, propofol and propofol+noise. Propofol was infused intravenously for 20 min prior to noise exposure with a loading dose of 5 mg·kg(-1) for 5 min and a maintenance infusion of 20 mg·kg(-1)·h(-1) for 135 min...

REVIEW
Sabri Soussi, Matthieu Legrand
Burn shock is characterized by profound hemodynamic alterations mainly associated with rapid loss of intravascular volume related to severe capillary leak. Thus, fluid resuscitation conventionally based on macrocirculatory targets is considered as a corner stone of initial management of patients with burns. Nonetheless, traditional markers such as blood pressure, urinary output, and cardiac output are helpful but do not sufficiently reflect the adequacy of perfusion and oxygenation at the microcirculatory level...

REVIEW
Philip Arnemann, Laura Seidel, Christian Ertmer
The ultimate goal of fluid therapy is to improve the oxygenation of cells by improving the cardiac output, thus improving microcirculation by optimizing macrocirculation. This haemodynamic coherence is often altered in patients with haemorrhagic shock and sepsis. The loss of haemodynamic coherence is associated with adverse outcomes. It may be influenced by the mechanisms of the underlying disease and properties of different fluids used for resuscitation in these critically ill patients. Monitoring microcirculation and haemodynamic coherence may be an additional tool to predict the response to fluid administration...
