PURPOSE OF REVIEW Treatment of Peyronie's disease with collagenase Clostridium histolyticum (CCh) has gained world-wide adoption following the phase III clinical trials IMPRESS I and II. However, the optimal treatment parameters remain largely unknown. Many groups have made modifications to CCh treatment in Peyronie's disease in recent years. This review aims to discuss the variations in CCh treatment reported and associated outcomes. RECENT FINDINGS Variations in CCh treatment protocols include administering higher CCh doses (0.9 mg) less frequently (q1month), use of home penile modeling, use of angulating penile traction devices, and vacuum therapy devices. Authors have reported different injection techniques to include three-point fans and tunneling techniques. Patient selection has expanded to include and evaluate responses among men with some extent of plaque calcification, and ventral curves. SUMMARY Since publication of the IMPRESS trials, several variations of CCh treatment have been reported with similar treatment responses to the original trials. However, future studies are required with prospective, randomized comparative designs to identify the optimal treatment strategies for men with Peyronie's disease.PURPOSE OF REVIEW The review presents a clinical algorithm for the evaluation and treatment for adolescents with Klinefelter's syndrome who desire fertility preservation. RECENT FINDINGS Sperm is present in the ejaculate in around 8% of men with Klinefelter's syndrome. Although most are severely oligospermic/azoospermic, 43-45% of men will have sperm found during a testicular sperm extraction, reaching up to 70% in adolescents. SUMMARY Klinefelter's syndrome (47, XXY) causes hypogonadotophic hypogonadism and severe oligospermia/azoospermia rendering natural conception rare. During puberty, boys often require testosterone replacement therapy to develop secondary sexual characteristics, which can further decrease spermatogenesis. There is a progressive decrease of testicular germ cells after the onset of puberty, suggesting that fertility evaluation and preservation should begin shortly thereafter. In adolescents desiring fertility evaluation, any testosterone therapy should be discontinued, hormones and gonadotrophins measured, and a semen analysis obtained. Adolescents with low testosterone are administered aromatase inhibitors, selective estrogen receptors modulators and/or human chorionic gonadotropin to increase endogenous testosterone production. After testosterone levels are normalized, semen analysis is performed, and cryopreservation encouraged if sperm is present. For those without sperm in the ejaculate, a testicular sperm extraction is offered.PURPOSE OF REVIEW The sensitivity of semen analysis for detection of infertility remains low. Many factors not measured in traditional semen analysis may contribute to male factor infertility. DNA fragmentation, oxidative stress, and sperm aneuploidy are three factors that may contribute further information to the evaluation when semen analysis is inconclusive. RECENT FINDINGS DNA fragmentation measures the destruction of and failure to repair damage to DNA. Increased DNA fragmentation has been used as a marker for oxidative stress as well as toxic exposure. Nintedanib The oxidative stress adduct measures DNA aberrations, which sperm cannot repair and has been used to support use of antioxidants. Lastly, the aneuploid sperm frequency is a quantitative measure of deviation from the normal chromosomal complement. Although elevated sperm aneuploid frequency has been associated with recurrent pregnancy loss and implantation failures, barriers remain to its routine use. SUMMARY We identified these three adjunctive tests, which have the potential to alter either management or counseling of patients with regards to male factor infertility. Elevated DNA fragmentation or significant sperm aneuploidy may suggest the need for further investigation or further preimplantation genetic testing prior to IVF. The oxidative stress adduct may lend further explanation and improved counseling of the infertile patient.PURPOSE OF REVIEW We will examine the current and future options in management of anemia in dialysis patients focusing on recent trials in iron supplementation and alternatives to erythropoietin-stimulating agents (ESAs). RECENT FINDINGS We review the literature on Erythropoietin (EPO)-stimulating agents, focusing on the risk benefits of various options available. We review the recent practice changing trial in iron supplementation in dialysis patients with chronic kidney disease and movements in the research on alternatives to EPO-stimulating agents primarily hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs). SUMMARY ESAs constitute the mainstay of treatment of anemia in dialysis and evidence does not support the preference of any one type over the other. But concerns exist about the cardiovascular safety of supra-physiological ESA levels. Iron supplementation has been shown to be a well tolerated method to decrease ESA doses while maintaining hemoglobin levels and recent evidence should result in a revisiting of the guidelines for iron supplementation. HIF-PHIs are potentially safe alternatives to ESAs that correct and maintain hemoglobin while maintaining physiological levels of erythropoietin. Ongoing phase III trials for these drugs will likely answer questions of long-term safety regarding these drugs.PURPOSE OF REVIEW The universal adoption of electronic health records, improvement in technology, and the availability of continuous monitoring has generated large quantities of healthcare data. Machine learning is increasingly adopted by nephrology researchers to analyze this data in order to improve the care of their patients. RECENT FINDINGS In this review, we provide a broad overview of the different types of machine learning algorithms currently available and how researchers have applied these methods in nephrology research. Current applications have included prediction of acute kidney injury and chronic kidney disease along with progression of kidney disease. Researchers have demonstrated the ability of machine learning to read kidney biopsy samples, identify patient outcomes from unstructured data, and identify subtypes in complex diseases. We end with a discussion on the ethics and potential pitfalls of machine learning. SUMMARY Machine learning provides researchers with the ability to analyze data that were previously inaccessible.
