Book Description
The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

Book Description
Upper Tract Urothelial Carcinoma represents the first book of its kind to be dedicated solely to UTUC. It's aim is to improve understanding and eventually care of a disease that is greatly understudied and underappreciated, yet commonly dealt with by many medical and urologic oncologists. The volume features new data regarding genetic susceptibility, gene expression studies and causative factors; contemporary concepts and controversies regarding diagnosis and staging of UTUC; prediction tools and their value in treatment decisions within each disease stage and patient selection and treatment options such as endoscopic management, distal ureterectomy, radical nephroureterectomy and chemotherapy. Up-to-date information regarding boundaries of surgical resection, indication and extent of lymphadenectomy is covered as well as the role of perioperative/neoadjuvant chemotherapy in patients with high-risk UTUC. Upper Tract Urothelial Carcinoma will be of great value to all Urologists, Medical Oncologists and fellows in Urologic Oncology as well as upper level residents in training in Urology and Medical Oncology.

Book Description
Nutrition in Kidney Disease, Second Edition addresses the relationships between nutrition and (1) normal kidney function and disease, (2) the progressiveness of chronic kidney disease (CKD) and strategies to prevent further compromise, and (3) the treatment and management of kidney failure especially during medical crises, such as acute kidney injury and its consequent nutritional therapies (e.g., enteral and parenteral nutrition). Demographic patterns, trends and outcomes in the current health care systems are explored in the United States and abroad. Disease prevention and management are presented over the entire lifespan, beginning with pregnancy, followed by infancy, childhood, adolescence, and adulthood, concluding with the elder years. Foundations for clinical practice are established by devoting a complete section towards conducting a comprehensive nutritional assessment, comprising of anthropometric, biochemical, clinical, physical parameters and psychosocial concerns unique to the kidney disease population. Nutritional therapy is also discussed across the spectrum of kidney disease, and pertinent aspects critical to successful management of disorders and conditions, such as bone disease, obesity, and nephrotic syndrome are explored. Nutrition in Kidney Disease, Second edition highlights cutting edge research in regards to exercise and functional outcomes, malnutrition and the inflammatory response, experimental therapies, and the use of complementary and alternative medicine, with a special emphasis on relevant preventative strategies.

Book Description
"They Leave Their Kidneys in the Fields takes the reader on an ethnographic tour of the melon and corn harvesting fields in California's Central Valley to understand why farmworkers die at work each summer. Laden with captivating detail of farmworkers' daily work and home lives, Horton examines how U.S. immigration policy and the historic exclusion of farmworkers from the promises of liberalism has made migrant farmworkers what she calls 'exceptional workers.' She explores the deeply intertwined political, legal, and social factors that place Latino migrants at particular risk of illness and injury in the fields, as well as the patchwork of health care, disability, and Social Security policies that provide them little succor when they become sick or grow old. The book takes an in-depth look at the work risks faced by migrants at all stages of life: as teens, in their middle-age, and ultimately as elderly workers. By following the lives of a core group of farmworkers over nearly a decade, Horton provides a searing portrait of how their precarious immigration and work statuses culminate in preventable morbidity and premature death"--Provided by publisher.

Book Description
This book is a comprehensive resource and up-to-date description of all urinary sediment constituents which are presented in bright-field mode and in phase-contrast mode. Thanks to numerous detailed images of urinary sediment constituents, the reader is able to easily compare what they view microscopically with high-resolution photographs and short films. The book is also designed to aid the identification of rare urine constituents in their native state without prior staining. It also features guidance on how set-up a microscope , microscopy techniques, and preanalytics. Exercises focused on microscopic analysis and diagnosis and a urinary sediment quiz reinforce key concepts to aid learning. Urine Sediment provides a practically applicable guide to the recognition of urinary sediment constituents. It is therefore a critical resource for trainees and experienced practitioners in urology, nephrology, gynecology and general practice who need to be able to accurately and quickly identify urine sediment constituents.

Book Description
This pocket manual is designed to guide medical professionals in acquiring skills in basic ultrasound imaging. It describes the most common scans performed at the patient’s bedside, specifically in the emergency department or intensive care unit. Following an overview of basic ultrasound principles, the use of this modality to visualize specific organ systems is described. In a quick-reference bulleted format, each chapter details indications, basic techniques (patient position, organ windows/views), probe placement, anatomy, pathology, pearls, and key points in ultrasound imaging. The extensive collection of images helps orient the reader in interpreting the scans, depicts anatomic landmarks, and identifies key pathologic findings for each organ system. Clinical Ultrasound: A Pocket Manual is an accessible guide to performing bedside ultrasound imaging for emergency medicine physicians, primary care physicians, critical care medicine providers, residents, and medical students.
