Growing evidence suggests the neurobiological mechanism upholding post-COVID-19 depression mainly relates to immune response and subsequent unresolved low-grade inflammation. Herein we exploit a broad panel of cytokines serum levels measured in COVID-19 survivors at one- and three-month since infection to predict post-COVID-19 depression. 87 COVID survivors were screened for depressive symptomatology at one- and three-month after discharge through the Beck Depression Inventory (BDI-13) and the Zung Self-Rating Depression Scale (ZSDS) at San Raffaele Hospital.

Background: Obesity and frailty are prevalent geriatric conditions that share some pathophysiological mechanisms and are associated with adverse clinical outcomes. The relationship between frailty, obesity, and polymorphism remains inadequately explored. Single nucleotide polymorphisms (SNPs) offer insights into genetic predispositions that may influence the development of both frailty and obesity.

Article Synopsis
  • Acute sarcopenia is a rapid decline in muscle mass and function in older adults after events like illness or surgery, affecting 28% to 69% of hospitalized patients but often goes undiagnosed.
  • Key factors contributing to acute sarcopenia include systemic inflammation, endocrine imbalances, and anabolic resistance, with interventions like early mobilization, resistance exercises, and nutritional support showing promise.
  • Future research should focus on continuous muscle assessments, finding biomarkers, and a team approach to manage sarcopenia effectively, emphasizing the importance of early interventions to prevent long-term disability.

Aging is a universal biological process characterized by a progressive, cumulative decline in homeostatic capabilities and physiological functions, which inevitably increases vulnerability to diseases. A number of molecular pathomechanisms and hallmarks of aging have been recognized, yet we miss a thorough understanding of their complex interconnectedness. This review explores the molecular and cellular mechanisms underlying human aging, with a focus on the multiple roles of high mobility group Box 1 protein (HMGB1), the archetypal damage-associated molecular pattern (DAMP) molecule.

  • Acute COVID-19 infection leads to elevated levels of neurofilament light chain (NfL), indicating potential damage to the nervous system.
  • A study of 103 COVID-19 patients revealed that NfL levels are significantly influenced by various circulating inflammatory markers, such as cytokines and chemokines.
  • These findings suggest that NfL could serve as a useful marker for neuronal damage linked to the inflammation caused by COVID-19.

Pre-existing mental disorders are considered a risk factor for severe COVID-19 outcomes, possibly because of higher vascular burden. Moreover, an unconventional platelet activation characterizes COVID-19 and contributes to inflammatory and thrombotic manifestations. In the light of the inflammation theory of mental disorders, we hypothesized that patients with mental disorders could be sensitive to the SARS-CoV-2 elicited platelet activation.

Seasonal rhythms affect the immune system. Evidence supports the involvement of immuno-inflammatory mechanisms in bipolar disorder (BD), with the neutrophil to lymphocyte ratio (NLR), and the systemic immune-inflammatory index (SII; platelets × neutrophils/lymphocytes) consistently reported to be higher in patients with BD than in HC, but seasonal rhythms of innate and adaptive immunity have never been studied. We retrospectively studied NLR and SII in 824 participants divided into three groups: 321 consecutively admitted inpatients affected by a major depressive episode in course of BD, and 255 consecutively admitted inpatients affected by obsessive-compulsive disorder (OCD; positive psychiatric control), and 248 healthy controls (HC).

Article Synopsis
  • The study examined pregnancy outcomes in women with autoimmune rheumatic diseases (ARD) enrolled in the Italian P-RHEUM.it cohort from 2018 to 2023, focusing on maternal and infant health.
  • Results showed that out of 866 pregnancies, 15.6% experienced maternal disease flares, 30.1% had obstetrical complications, and 91.7% resulted in live births, with a relatively low rate of perinatal deaths and complications.
  • The research concluded that effective preconception counseling and proper medication management during pregnancy may help reduce disease-related risks, suggesting that outcomes for women with ARD were comparable to those in the general obstetric population.

Article Synopsis
  • This study investigated the lasting effects of COVID-19, focusing on how immune response markers in the blood are linked to ongoing symptoms after recovery.
  • The research involved 94 adults who had been infected with SARS-CoV-2 and looked at various immune markers at different stages: during acute illness, and then 1 and 6 months later.
  • Results showed that while baseline immune markers didn't predict ongoing symptoms, a decrease in one specific marker (PTX3) over time was linked to lower levels of depression and anxiety six months post-infection.

Introduction: Chronic autoimmune (type 1 diabetes and coeliac disease) and metabolic/cardiovascular (type 2 diabetes, dyslipidaemia, hypertension) diseases are highly prevalent across all age ranges representing a major public health burden. Universal screening for prediction/early identification of these conditions is a potential tool for reducing their impact on the general population. The aim of this study is to assess whether universal screening using capillary blood sampling is feasible at a population-based level.

Introduction: The COVID-19 pandemic represents the most severe health and socioeconomic crisis of our century. It began with the first reports in China, in the Wuhan region in December 2019, and quickly spread worldwide, causing a new Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Among the population most at risk of infection and developing severe forms of the disease are the elderly and healthcare workers, who are more exposed to infected individuals.

Older individuals face an elevated risk of developing geriatric syndromes when confronted with acute stressors like COVID-19. We assessed the connection between in-hospital delirium, malnutrition, and frailty in a cohort of COVID-19 survivors. Patients aged ≥65, hospitalized in a tertiary hospital in Milan for SARS-CoV-2 pneumonia, were enrolled and screened for in-hospital delirium with the 4 'A's Test (4AT) performed twice daily (morning and evening) during hospital stay.

Introduction: SARS-CoV-2 mRNA vaccinations elicit both virus-specific humoral and T-cell responses, but a complex interplay of different influencing factors, such as natural immunity, gender, and age, guarantees host protection. The present study aims to assess the immune dynamics of humoral, T-cell response, and influencing factors to stratify individual immunization status up to 10 months after Comirnaty-vaccine administration.

Methods: To this aim, we longitudinally evaluated the magnitude and kinetics of both humoral and T-cell responses by serological tests and enzyme-linked immunospot assay at 5 time points.

The efficacy of low molecular weight heparin (LMWH) is well-established in patients with obstetric antiphospholipid syndrome (O-APS). Their role in women with unexplained recurrent pregnancy loss (U-RPL) and late obstetrical complications (intrauterine growth restriction, IUGR and preeclampsia) is controversial. Here we compared rates of miscarriage and late obstetrical complications in RPL patients diagnosed with O-APS (n = 57) or hereditary thrombophilia (n = 25) (both assuming LMWH from the beginning of pregnancy) and in patients with a history of U-RPL (n = 118), assuming or not LMWH, followed at the 'Pregnancy at risk' and 'Recurrent pregnancy loss' outpatient clinics at the San Raffaele Hospital from April 2010 to April 2020.
