The use of SGLT2 inhibitors (SGLT2is) has been found in large clinical studies to slow the progression of chronic kidney disease (CKD) and to lower the risk of acute kidney injury (AKI). Recent reports suggest that SGLT2is may also reduce the likelihood of developing radiocontrast-associated nephropathy (CAN) following contrast-enhanced imaging and intravascular interventions. This review underscores potential pitfalls and confounders in these studies and calls for caution in adopting their conclusions regarding the safety and renoprotective potency of SGLT2is, in particular in patients at high risk, with advanced CKD and hemodynamic instability undergoing coronary intervention.

Apical ballooning syndrome, commonly known as Takotsubo syndrome, is a distinct cardiomyopathy often resembling acute myocardial infarction in presentation. Takotsubo syndrome patients exhibit varied patterns of left ventricular wall motion abnormalities, most frequently apical dyskinesis with basal hyperkinesis, that are characteristically transient. Although emotional or physical stressors precipitate Takotsubo syndrome in most cases, a significant proportion presents without identifiable triggers, with a pronounced female predominance.

Hemodialysis patients are susceptible to excess volume accumulation, particularly over the 2-day interval (long interdialytic gap), resulting in higher interdialytic weight gain (IDWG). We thought to determine whether a novel device designed to enhance fluid and salt loss by activating the eccrine sweat glands can mitigate IDWG. Patients eligible for the study were undergoing regular hemodialysis for ≥3 months, without residual renal function, and with IDWG (as a percentage of IDWG/dry body weight) ≥2.

Article Synopsis
  • This study looked at two ways to treat a type of liver cancer called hepatoblastoma in kids: doing surgery right away or giving chemotherapy first and then doing surgery later.
  • They compared the results from over 500 patients to see which method worked better for survival and recovery.
  • The study showed that both methods had similar results in terms of surgery success and complications, but some patients with certain conditions did better with surgery first.

Background: Quantification of left atrial (LA) conduit function and its contribution to left ventricular (LV) filling is challenging because it requires simultaneous measurements of both LA and LV volumes. The functional relationship between LA conduit function and the severity of diastolic dysfunction remains controversial. We studied the role of LA conduit function in maintaining LV filling in advanced diastolic dysfunction.

Background: Electroporation is a promising nonthermal ablation method for cardiac arrhythmia treatment. Although initial clinical studies found electroporation pulsed-field ablation (PFA) both safe and efficacious, there are significant knowledge gaps concerning the mechanistic nature and electrophysiological consequences of cardiomyocyte electroporation, contributed by the paucity of suitable human in vitro models. Here, we aimed to establish and characterize a functional in vitro model based on human-induced pluripotent stem cells (hiPSCs)-derived cardiac tissue, and to study the fundamentals of cardiac PFA.

Article Synopsis
  • Understanding the cause of cardiac arrest (CA) is crucial for making treatment choices, and this study focuses on the effectiveness of high-sensitivity cardiac troponin-I (hs-cTnI) in such cases.
  • A retrospective study of 201 patients who experienced out-of-hospital cardiac arrest (OHCA) found significant differences in hs-cTnI levels between those with acute myocardial infarction (AMI) and those without.
  • Findings indicate that peak hs-cTnI and the rate of increase (upslope) can effectively differentiate between AMI and non-AMI causes of CA, suggesting these measures can support other diagnostic approaches.

Purpose: A comprehensive operative report for cancer surgery is crucial for accurate disease staging, risk stratification, and therapy escalation/de-escalation, which affects the outcome. Narrative operative reports may fail to include some critical findings. Furthermore, standardized operative reports can form the basis of a local registry, which is often lacking in limited-resource settings (LRSs).

Article Synopsis
  • Congestive heart failure (CHF) negatively impacts kidney function, with the activation of the renin-angiotensin-aldosterone system (RAAS) leading to issues like salt/water retention and cardiac hypertrophy.
  • In a study on rats, acute administration of angiotensin 1-7 (Ang 1-7) showed positive effects on kidney function parameters like urinary flow and filtration rates, especially in non-CHF rats.
  • Chronic treatment with Ang 1-7 significantly improved kidney function and reduced cardiac hypertrophy in CHF rats, suggesting it could be a potential therapeutic agent for managing CHF-related complications.

Aims: The development of acute heart failure (AHF) is a critical decision point in the natural history of the disease and carries a dismal prognosis. The lack of appropriate risk-stratification tools at hospital discharge of AHF patients significantly limits clinical ability to precisely tailor patient-specific therapeutic regimen at this pivotal juncture. Machine learning-based strategies may improve risk stratification by incorporating analysis of high-dimensional patient data with multiple covariates and novel prediction methodologies.

Introduction: Wilms tumor therapy in low- and middle-income countries (LMICs) relies on treatment protocols adapted to resource limitations, but these protocols have rarely been evaluated in real-world settings. Such evaluations are necessary to identify high-impact research priorities for clinical and implementation trials in LMICs. The purpose of this study was to identify highest priority targets for future clinical and implementation trials in sub-Saharan Africa by assessing outcomes of a resource-adapted treatment protocol in Malawi.

Small cell undifferentiated (SCU) histology and alpha-fetoprotein (AFP) levels below 100 ng/mL have been reported as poor prognostic factors in hepatoblastoma (HB); subsequent studies reported mutations in some SCU HBs confirming the diagnosis of rhabdoid tumor. The Children's Hepatic tumors International Collaboration (CHIC) database was queried for patients with HB who had AFP levels less than 100 ng/mL at diagnosis or were historically diagnosed as SCU HBs. Seventy-three of 1605 patients in the CHIC database were originally identified as SCU HB, HB with SCU component, or HB with low AFP levels.

Background: Current treatment of fluid retention in heart failure relies primarily on diuretics. However, adequate decongestion is not achieved in many patients. We aimed to study the feasibility and short-term performance of a novel approach to remove fluids and sodium directly from the interstitial compartment by enhancing sweat rate.

Article Synopsis
  • - Congestive heart failure (HF) results from impaired heart function leading to reduced blood flow, which triggers neurohormonal systems causing fluid retention and symptoms like dyspnea and fatigue.
  • - The heart and kidneys interact in HF through mechanisms like reduced blood flow and renal perfusion, leading to hypoxia in the renal tubules and further complications due to the activation of systems like RAAS and SNS.
  • - Despite the presence of beneficial hormones like ANP and BNP, the negative effects of neurohormonal activation, such as continued sodium and water retention, dominate, contributing to worsening heart health and renal function.

Article Synopsis
  • Acute heart failure (AHF) can lead to high lactate levels and various acid-base imbalances, which may indicate worse outcomes for patients.
  • In a study of 4,012 normotensive AHF patients, 38% had elevated lactate; this was linked to an increased risk of in-hospital death, especially in cases of acidosis and alkalosis.
  • The presence of hyperlactataemia and different acid-base disorders was common in AHF patients and significantly associated with higher mortality risk, regardless of blood pressure status.

Diet quality is now established as the single leading predictor of perennial premature death in modern countries. However, practice at scale in modern medicine is driven as much by financial as clinical imperatives and yet, the ability to quantify the potential ROI of Food as medicine (FaM) interventions is limited by a lack of data. Utilizing a novel advance in dietary assessment and data from the peer-reviewed literature, we constructed and tested a web-based calculator simulating the return-on-investment associated with FaM interventions.
