Derivation and validation of a biomarker-based clinical algorithm to rule out sepsis from noninfectious systemic inflammatory response syndrome at emergency department admission: a multicenter prospective study

Objectives: To derive and validate a predictive algorithm integrating a nomogram-based prediction of the pretest probability of infection with a panel of serum biomarkers, which could robustly differentiate sepsis/septic shock from noninfectious systemic inflammatory response syndrome. Design: Multicenter prospective study. Setting: At emergency department admission in five University hospitals. Patients: Nine-hundred forty-seven adults in inception cohort and 185 adults in validation cohort. Interventions: None.

Inflammatory biomarkers and clinical judgment in the emergency diagnosis of urgent abdominal pain

BACKGROUND: The early diagnosis of urgent abdominal pain (UAP) is challenging. Most causes of UAP are associated with extensive inflammation. Therefore, we hypothesized that quantifying inflammation using interleukin-6 and/or procalcitonin would provide incremental value in the emergency diagnosis of UAP. METHODS: This was an investigator-initiated prospective, multicenter diagnostic study enrolling patients presenting to the emergency department (ED) with acute abdominal pain.

Neuropsychological, electrophysiological, and neuroimaging biomarkers for REM behavior disorder

Introduction: Rapid eye movement (REM) sleep behavior disorder (RBD) is a REM sleep parasomnia characterized by dream enacting behaviors allowed by the loss of physiological atonia during REM sleep. This disorder is recognized as a prodromal stage of neurodegenerative disease, in particular Parkinson’s Disease (PD) and Dementia with Lewy Bodies (DLB). Therefore, a timely identification of biomarkers able to predict an early conversion into neurodegeneration is of utmost importance.

Salivary alpha-synuclein in the diagnosis of parkinson's disease and progressive supranuclear palsy

Introduction: Alpha-synuclein (α-syn) aggregation is the pathological hallmark of Parkinson's Disease (PD). In this study, we measured α-syn total (α-syn total ), oligomeric α-syn (α-syn olig ) and α-syn olig /α-syn total ratio in the saliva of patients affected by PD and in age and sex-matched healthy subjects. We also compared salivary α-syn total measured in PD with those detected in Progressive Supranuclear Palsy (PSP), in order to assess whether salivary α-syn can be used as a biomarker for PD and for the differential diagnosis between PD and PSP.

Therapeutic vaccines and immune checkpoints inhibition options for gynecological cancers

Treatments for gynecological cancer include surgery, chemotherapy, and radiation. However, overall survival is not improved, and novel approaches are needed. Immunotherapy has been proven efficacious in various types of cancers and multiple approaches have been recently developed. Since numerous gynecological cancers are associated to human papilloma virus (HPV) infections, therapeutic vaccines, targeting HPV epitopes, have been developed.

Src nuclear localization and its prognostic relevance in human osteosarcoma

Osteosarcoma is the most common malignant bone tumor in children and young adults.
The identification of proteins which exhibit different subcellular localization in low- versus
high-risk osteosarcoma can be instrumental to obtain prognostic information and to
develop innovative therapeutic strategies. Beside the well-characterized membrane and
cytoplasmic localization of Src protein, this study evaluated the prognostic relevance of its
so-far unknown nuclear compartmentalization. We analyzed the subcellular distribution

Secreted miR-210-3p as non-invasive biomarker in clear cell renal cell carcinoma

The most common subtype of renal cell carcinoma (RCC) is clear cell RCC (ccRCC).
It accounts for 70-80% of all renal malignancies representing the third most common
urological cancer after prostate and bladder cancer. The identification of non-invasive
biomarkers for the diagnosis and responsiveness to therapy of ccRCC may represent
a relevant step-forward in ccRCC management. The aim of this study is to evaluate
whether specific miRNAs deregulated in ccRCC tissues present altered levels also

Precision medicine and drug development in Alzheimer's disease: the importance of sexual dimorphism and patient stratification

Neurodegenerative diseases (ND) are among the leading causes of disability and mortality. Considerable sex differences exist in the occurrence of the various manifestations leading to cognitive decline. Alzheimer's disease (AD) exhibits substantial sexual dimorphisms and disproportionately affects women. Women have a higher life expectancy compared to men and, consequently, have more lifespan to develop AD.

Two-year longitudinal monitoring of amnestic mild cognitive impairment patients with prodromal alzheimer's disease using topographical biomarkers derived from functional magnetic resonance imaging and electroencephalographic activity

Auditory "oddball" event-related potentials (aoERPs), resting state functional magnetic resonance imaging (rsfMRI) connectivity, and electroencephalographic (rsEEG) rhythms were tested as longitudinal functional biomarkers of prodromal Alzheimer's disease (AD). Data were collected at baseline and four follow-ups at 6, 12, 18, and 24 months in amnesic mild cognitive impairment (aMCI) patients classified in two groups: "positive" (i.e., "prodromal AD"; n = 81) or "negative" (n = 63) based on a diagnostic marker of AD derived from cerebrospinal samples (Aβ42/P-tau ratio).
