Background: Renal cell carcinoma (RCC) is a common malignancy, and nephrectomy is the mainstay of treatment for non-metastatic disease. The choice of surgery depends on the risks of oncologic recurrence, kidney function decline, and perioperative complications. This study aimed to identify factors associated with adverse post-operative outcomes in RCC patients undergoing nephrectomy at Townsville University Hospital (TUH).

The use of next-generation sequencing technologies such as exome and genome sequencing in research and clinical care has transformed our understanding of the molecular architecture of genetic kidney diseases. Although the capability to identify and rigorously assess genetic variants and their relationship to disease has advanced considerably in the past decade, the curation of clinically relevant relationships between genes and specific phenotypes has received less attention, despite it underpinning accurate interpretation of genomic tests. Here, we discuss the need to accurately define gene-disease relationships in nephrology and provide a framework for appraising genetic and experimental evidence critically.

Article Synopsis
  • Autosomal dominant polycystic kidney disease (ADPKD) is a major hereditary kidney disease, with traditional treatment focusing on symptom management rather than disease progression.
  • Recent advancements in understanding the disease's mechanisms have led to new medications aimed at halting its progression, though their effectiveness for all patients remains uncertain.
  • The review aims to assess the safety and impact of these interventions using patient-focused outcomes while analyzing data from various clinical studies and trials.

Article Synopsis
  • Mitochondrial donation is now legally allowed in Australia to help prevent the passing of mitochondrial diseases from mothers to their children as part of a clinical trial.
  • A systematic literature review analyzed five cohort studies and 19 case reports on how mitochondrial disease affects pregnancy.
  • While many women with mitochondrial disease experience no negative health effects during pregnancy, there is a risk of serious complications, leading to proposed guidelines for preconception counseling and antenatal care.

(1) Background: Mid-level managers in healthcare are central to improving safety and quality of care. Their ability in demonstrating leadership and management competency in their roles and supporting frontline managers and frontline staff has a direct effect on staff retention and turn-over. Yet, investment in their professional development and support for mid-level managers is often neither adequate nor effective, and high rates of staff turnover are evident.

New evidence indicates potential benefit of genomics to illuminate nonkidney monogenic morbidity and mortality risk among kidney transplant recipients. This might be of direct relevance to an equivalent proportion of patients to those who harbor a monogenic kidney disease. Further evidence and replication are indicated, including a broadening potential range of monogenic and polygenic opportunities to improve clinical outcomes.

Introduction: Kidney stones is common with an increasing trend over time and has been well studied in the general population. However, incidence and outcomes of kidney stones leading to kidney failure (KF) and receiving kidney replacement therapy (KRT) is poorly examined. We examined the incidence of KF due to kidney stones and compared outcomes to KRT patients due to other causes.

Background: Metformin has been used in the management of diabetes for decades. It is an effective, low-cost intervention with a well-established safety profile. Emerging evidence suggests that metformin targets a number of pathways that lead to chronic kidney damage, and long-term use may, therefore, slow the rate of kidney function decline and chronic kidney disease (CKD) progression.
