INTRODUCTION: Streptococcus agalactiae (Group B Streptococcus , GBS) is a leading pathogen of neonatal sepsis. The host-pathogen interactions underlying the progression to life-threatening infection in newborns are incompletely understood. Macrophages are first line in host defenses against GBS, contributing to the initiation, amplification, and termination of immune responses. The goal of this study was to compare the response of newborn and adult monocyte-derived macrophages (MDMs) to GBS...

The endothelium is a biologically active interface with multiple functions, some of them common throughout the vascular tree, and others that depend on its anatomical location. Endothelial cells are continually exposed to cellular and humoral factors, and to all those elements (biological, chemical, or hemodynamic) that circulate in blood at a certain time. It can adapt to different stimuli but this capability may be lost if the stimuli are strong enough and/or persistent in time. If the endothelium loses its adaptability it may become dysfunctional, becoming a potential real danger to the host...

Impetigo herpetiformis (IH) is a rare dermatosis that can manifest during the last trimester of pregnancy. It has the potential to cause fatality to both the mother and the fetus. After birth, it often vanishes spontaneously and rapidly. Clinically and histologically, it resembles pustular psoriasis, leading some authors to call it "the pustular psoriasis of pregnancy." Steroids were previously the treatment of choice, but treatment remains challenging. A dermatologist with experience in skin conditions during pregnancy should assess any generalized pustular psoriasis instances...

Renal cysts are prevalent conditions and are often diagnosed incidentally. The infection of renal cysts is an uncommon presentation. It is even more rare in solitary simple cysts than in autosomal dominant polycystic kidney disease (ADPKD). Patients with infected renal cysts can have variable presenting symptoms; however, almost universally, they have flank pain. Here, we report a case of a solitary renal cyst infection in the absence of flank pain, a relatively rare condition. A 60-year-old male patient presented to our emergency department (ED) for ongoing periumbilical/lower abdominal pain, chills, and high-grade fever...

Calcific uremic arteriolopathy, or calciphylaxis, is a highly morbid, life-threatening syndrome of microvascular calcification leading to progressive skin necrosis. It affects 1-4% of the population with end-stage renal disease (ESRD) and is rarely seen in other conditions. The one-year mortality rate is 80% for patients with ulcerations. There is no evidence-based treatment, and the response to therapy is poor; thus, it creates a serious therapeutic challenge for clinicians. Our aim is to discuss a diagnostic approach and management of calciphylaxis and to raise awareness about this condition among the medical community...

BACKGROUND: There is currently no biomarker that can reliably identify sepsis, despite recent scientific advancements. We systematically evaluated the value of lysosomal genes for the diagnosis of pediatric sepsis. METHODS: Three datasets (GSE13904, GSE26378, and GSE26440) were obtained from the gene expression omnibus (GEO) database. LASSO regression analysis and random forest analysis were employed for screening pivotal genes to construct a diagnostic model between the differentially expressed genes (DEGs) and lysosomal genes...

Long considered a "forgotten disease" of a bygone era, the apparent reemergence of Lemierre syndrome highlights the need for awareness of this rare condition to ensure timely diagnosis and treatment. Lemierre syndrome should be suspected in young adults presenting with a chest or neck infection and requires prolonged antibiotic therapy, surgical drainage of collections, and often anticoagulation.

Patients with septic shock complicated by septic cardiomyopathy (SCM) can be extremely ill and at high risk for mortality. If early assessment of cardiac function is neglected during treatment, sepsis may be further exacerbated. We report a 77-year-old male patient with severe septic shock who underwent intraoperative transesophageal echocardiography (TEE) because of progressive circulatory instability, SCM was diagnosed. Further perioperative treatment to support the circulation was successfully adjusted based on TEE and pulse index continuous cardiac output (CO) by ProAQT/PulsioFlex hemodynamic monitoring...

BACKGROUND AND OBJECTIVES: The safety and efficacy of granulocyte-colony stimulating factor (G-CSF) for the treatment of acute-on-chronic liver failure (ACLF) remain controversial. This meta-analysis aimed to evaluate the effectiveness and safety of G-CSF in treating ACLF. METHODS: The estimated pooled risk ratio (RR) and 95% confidence interval (CI) assessed the treatment effects of G-CSF. Mean differences (MD) and 95% confidence intervals were used to analyze continuous data...

INTRODUCTION: Fetal infection during labor with fetal inflammatory response syndrome (FIRS) is associated with neurodevelopmental disabilities, cerebral palsy, neonatal sepsis, and mortality. Current methods to diagnose FIRS are inadequate. Thus, the study aim was to explore whether fetal heart rate variability (HRV) analysis can be used to detect FIRS. MATERIAL AND METHODS: In chronically instrumented near-term fetal sheep, lipopolysaccharide (LPS) was injected intravenously to model FIRS...

Severe urinary tract infections occasionally cause sepsis and disseminated intravascular coagulation (DIC). We examined the efficacy of recombinant thrombomodulin (rTM) for treating DIC caused by urosepsis. We enrolled 40 patients who were diagnosed with DIC caused by urosepsis at our hospital between April 2018 and May 2022. Twenty-six patients were treated with rTM (rTM group), while 14 patients did not receive rTM (non-rTM group). The DIC score before treatment in the rTM group was significantly higher than that in the non-rTM group (P<0...

Streptococcus agalactiae (Group B Streptococcus; GBS) is a common cause of sepsis in neonates. Previous work detected GBS DNA in the placenta in ~5% of women before the onset of labour, but the clinical significance of this finding is unknown. Here we re-analysed this dataset as a case control study of neonatal unit (NNU) admission. Of 436 infants born at term (≥37 weeks of gestation), 7/30 with placental GBS and 34/406 without placental GBS were admitted to the NNU (odds ratio (OR) 3.3, 95% confidence interval (CI) 1...

AIMS: Sepsis represents a profound proinflammatory response with a major contribution from oxidative injury. Here we evaluated possible impact of heavy metal scavenger metallothionein (MT) on endotoxin lipopolysaccharide (LPS)-induced oxidative stress, endoplasmic reticulum (ER) stress, autophagy, and ferroptosis enroute to myocardial injury along with interplay among these stress domains. MATERIALS AND METHODS: Echocardiographic, cardiomyocyte mechanical and intracellular Ca2+ responses were monitored in myocardia from WT and transgenic mice with cardiac-selective MT overexpression challenged with LPS...

Anaphylaxis is a life-threatening condition that involves severe cutaneous, respiratory, and cardiovascular symptoms. Disseminated intravascular coagulation (DIC) is an acquired, widespread activation of coagulation that can be caused by infectious conditions (e.g., sepsis) and noninfectious conditions. The onset of DIC following anaphylaxis is not commonly known, and information regarding the pathomechanism linking anaphylaxis to DIC is scarce. Further, demographic and clinical data in anaphylaxis-induced DIC are still missing to this day...
