Ischemia/reperfusion injury (I/R) is a leading cause of acute kidney injury (AKI) in conditions like kidney transplants, cardiac surgeries, and nephrectomy, contributing to high global mortality and morbidity. This study aimed to analyze the protective effects of 2'-hydroxychalcones in treating I/R-induced AKI by targeting key pathological pathways. Considering strong antioxidant action along with other pharmacological roles of chalcone derivatives, six 2'-hydroxychalcones were synthesized via Claisen-Schmidt condensation and analyzed for their protective effects in an I/R induced AKI model using HK-2 cells.

To evaluate the urinary biomarkers related to sepsis in preterm newborns (NBs) and to investigate the predictive capacity of these biomarkers for a longer hospital stay. Serum and urine were collected from 27 healthy NBs, 24 NBs with neonatal infection without sepsis and 11 NBs with sepsis for the measurement of sindecan-1, lipocalin associated with urinary neutrophil gelatinase (uNGAL), urinary cystatin-C (uCysC) and urinary kidney injury molecule-1. Levels of uNGAL and urinary cystatin-C were elevated in NBs with sepsis and neonatal infection, and uNGAL was significant predictor of hospital stay longer than 30 days (odds ratio: 1.

Arboviruses are endemic in several countries and represent a worrying public health problem. The most important of these diseases is dengue fever, whose numbers continue to rise and have reached millions of annual cases in Brazil since the last decade. Other arboviruses of public health concern are chikungunya and Zika, both of which have caused recent epidemics, and yellow fever, which has also caused epidemic outbreaks in our country.

Article Synopsis
  • The study examined factors predicting in-hospital mortality in patients hospitalized for COVID-19 with silent hypoxemia in Brazil from January to June 2021.
  • Among 46,102 patients, those who died were generally older, had more comorbidities, and required more intensive medical support compared to survivors.
  • Key findings showed that advanced age, comorbidities, and respiratory distress were linked to higher mortality risk, while experiencing a cough and needing non-invasive respiratory support were protective factors against death.

Chronic kidney disease (CKD) represents one of today's main public health problems. Serum creatinine measurement and estimation of the glomerular filtration rate (GFR) are the main tools for evaluating renal function. There are several equations to estimate GFR, and CKD-EPI equation (Chronic Kidney Disease - Epidemiology) is the most recommended one.

Objective: To assess whether the use of ELMO, a helmet for noninvasive ventilation created in Brazil, had a positive impact on the prognosis of patients with hypoxemic respiratory failure caused by severe COVID-19.

Methods: This is a retrospective study of 50 critically ill COVID-19 patients. Epidemiological, clinical, and laboratory data were collected on ICU admission, as well as before, during, and after ELMO use.

Article Synopsis
  • The study aimed to assess how well vascular biomarkers can predict the need for hemodialysis in critically ill COVID-19 patients.
  • It involved 58 patients in the ICU, measuring biomarkers like VCAM-1 and angiopoietins upon admission.
  • The results indicated that VCAM-1 and the Ang-2/Ang-1 ratio were significant predictors for both dialysis necessity and mortality risk, with specific cutoff values helping to identify high-risk patients.

Background: The clinical picture of coronavirus disease 2019 (COVID-19)-associated sepsis is similar to that of sepsis of other aetiologies. The present study aims to analyse the role of syndecan-1 (SDC-1) as a potential predictor of septic shock in critically ill patients with COVID-19.

Methods: This is a prospective study of 86 critically ill patients due to COVID-19 infection.

Predicting risk factors for death in leptospirosis is challenging, and identifying high-risk patients is crucial as it might expedite the start of life-saving supportive care. Admission data of 295 leptospirosis patients were enrolled, and a machine-learning approach was used to fit models in a derivation cohort. The comparison of accuracy metrics was performed with two previous models-SPIRO score and quick SOFA score.

This study aimed to investigate the association between novel biomarkers and renal injury in people with HIV (PWH). A cohort study was carried out with PWH under chronic use of antiretroviral therapy (ART), followed at a public outpatient service. Clinical and laboratory parameters of the patients were evaluated year by year, from 2015 [at baseline (year 1, Y1)] to 2019 [year 5 (Y5)].

Article Synopsis
  • The tropics encompass over 125 countries with a population projected to increase by 60% in the coming decades, facing widespread public health issues like infectious diseases and poor healthcare access.
  • Many tropical diseases, such as leptospirosis and dengue, can lead to acute kidney injury (AKI) through various mechanisms, with contributions from toxins and environmental factors exacerbating the condition.
  • The article emphasizes the importance of understanding the causes, prevention, and management of AKI in tropical regions, highlighting that many of these health issues are potentially preventable and treatable.

  • Many patients with chronic kidney disease on dialysis own smartphones, with 64% reporting ownership, but only a small fraction (3.1%) are aware of kidney-related apps.
  • Despite this, 59.3% believe that mobile applications could aid in managing their condition effectively.
  • The study highlights that smartphone ownership correlates with higher education and income levels, and is associated with better adherence to treatment regimes.

Objective: To investigate risk factors for mortality in dengue.

Methods: We performed a systematic review and meta-analysis searching MEDLINE, Embase, SciELO, LILACS Bireme, and OpenGrey databases to identify eligible observational studies of patients with dengue, of both genders, aged 14 years or older, that analysed risk factors associated with mortality and reported adjusted risk measures with their respective confidence intervals (CIs). We estimated the pooled weighted mean difference and 95% CIs with a DerSimonian and Laird random-effects model.
