Article Synopsis
  • Peritoneal fibrosis involves the abnormal production of extracellular matrix proteins, leading to thickening of the peritoneal membrane, often due to conditions from clinical practices like peritoneal dialysis and surgery.
  • This condition results from inflammation and injury to the membrane, contributing to fibrosis and the formation of myofibroblasts, which play a key role in these changes.
  • Understanding the molecular mechanisms of peritoneal fibrosis is crucial for developing therapies to prevent deterioration and restore membrane function.

Paramount efforts worldwide are seeking to increase understanding of the basic virology of SARS-CoV-2, characterize the spectrum of complications associated with COVID-19, and develop vaccines that can protect from new and recurrent infections with SARS-CoV-2. While we continue learning about this new virus, it is clear that 1) the virus is spread via the respiratory route, primarily by droplets and contact with contaminated surfaces and fomites, as well as by aerosol formation during invasive respiratory procedures; 2) the airborne route is still controversial; and 3) that those infected can spread the virus without necessarily developing COVID-19 (ie, asymptomatic). With the number of SARS-CoV-2 infections increasing globally, the possibility of co-infections and/or co-morbidities is becoming more concerning.

The impact of the coronavirus disease (COVID-19), caused by the novel coronavirus SARS-CoV-2, continues to be widespread, with more than 100 million cases diagnosed in more than 220 countries since the virus was first identified in January 2020. Although patients with mild to moderate forms of COVID-19 could be efficiently managed at home, thus reducing the pressure on the healthcare system and minimizing socio-psychological impact on patients, no trial has been proposed, conducted, or even published on COVID-19 home therapy to date. These expert opinions provide indications on the therapeutical at home management of COVID-19 patients, based on the evidence from the literature and on current guidelines.

Coronavirus disease 2019 (COVID-19) can act as a dual prong attack against management of people living with human immunodeficiency virus (HIV); it induces harm on both individual and national levels. People living with HIV may show rapid deterioration in severe acute respiratory syndrome coronavirus 2 infection as a result of physiological or psychological vulnerability. Additionally, the spread of COVID-19-especially in low- and middle-income countries-may limit HIV control measures, delivery and linkage to HIV care and prevention.

Article Synopsis
  • Since December 2019, the rapid spread of SARS-CoV-2 has led to a global pandemic, with disease severity varying based on individual health conditions and a lack of effective prognostic markers.
  • Researchers conducted 16S rRNA gene sequencing on 21 COVID-19 patients, revealing significant alterations in their nasal/oropharyngeal microbiota compared to controls, with specific metrics (Chao1 and Shannon indices) indicating varying levels of microbiota diversity.
  • Notably, ICU patients exhibited complete depletion of certain bacterial groups, while other coronaviruses showed different microbiota profiles, suggesting that understanding these microbial changes could aid in patient stratification and potential new treatment approaches.

  • In 2008, guidelines were established for researching autophagy, which has since gained significant interest and new technologies, necessitating regular updates to monitoring methods across various organisms.
  • The new guidelines emphasize selecting appropriate techniques to evaluate autophagy while noting that no single method suits all situations; thus, a combination of methods is encouraged.
  • The document highlights that key proteins involved in autophagy also impact other cellular processes, suggesting genetic studies should focus on multiple autophagy-related genes to fully understand these pathways.

It is not yet entirely clear what is the relevance of skin symptoms and what clinical implications are related to their appearance in COVID-19 patients. We describe two cases of COVID-19-associated pneumonia, which presented skin manifestations in advanced stage of illness, when nasopharyngeal swabs became negative for SARS-CoV-2. The first case presented erythematous, maculopapular lesions; the second developed petechial, vesicular and blood-encrusted lesions on the limbs.

Background: The aim of this secondary analysis of the TESEO cohort is to identify, early in the course of treatment with tocilizumab, factors associated with the risk of progressing to mechanical ventilation and death and develop a risk score to estimate the risk of this outcome according to patients' profile.

Methods: Patients with COVID-19 severe pneumonia receiving standard of care + tocilizumab who were alive and free from mechanical ventilation at day 6 after treatment initiation were included in this retrospective, multicenter cohort study. Multivariable logistic regression models were built to identify predictors of mechanical ventilation or death by day-28 from treatment initiation and β-coefficients were used to develop a risk score.

Background: The highly variable manifestation of the COVID-19 disease, from completely asymptomatic to fatal, is both a clinical and a public health issue. The criteria for discharge of hospitalized patients have been based so far on the negative result of Real-Time Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) tests, but the persistence of viral fragments may exceed that of the integral virus by weeks. The aim of our study was to verify the clearance of the virus at viral culture in patients hospitalized for COVID-19 that have clinically recovered but are still positive on nasopharyngeal swab.

Article Synopsis
  • - The study investigated whether administering heparin in hospitals improves survival rates among COVID-19 patients, due to a linked hypercoagulable condition that can worsen the disease.
  • - An analysis of 2,574 patients across Italy showed that 70.1% received heparin, leading to significantly lower death rates (7.4 vs. 14.0 per 1,000 person-days) among those treated with heparin.
  • - The findings suggest that heparin is associated with a 40% reduction in death risk, especially for critically ill patients, indicating its potential benefit, although further randomized clinical trials are necessary for definitive guidance.

Article Synopsis
  • - The study highlights that many individuals infected with SARS-CoV-2 can be asymptomatic, with infection severity varying from mild symptoms to critical respiratory issues, where hypercoagulability can lead to death.
  • - A case presented an asymptomatic COVID-19 patient who, despite testing negative, had a large blood clot in the pulmonary artery that resulted in death; post-mortem analysis showed extensive vascular issues in various organs.
  • - Findings suggest asymptomatic patients are still at risk of developing serious thrombotic complications, indicating the need for better screening and early antithrombotic treatments even for those without symptoms.

Scope: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has become pandemic, reaching almost one million death worldwide. At present standard treatment for coronavirus disease 2019 (COVID-19) is not well defined because the evidence, either from randomized or observational studies, with conflicting results, has led to rapid changes in treatment guidelines. Our aim was to narratively summarize the available literature on the management of COVID-19 in order to combine current evidence and interpretation of the data by experts who are treating patients in the frontline setting.

In severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) critically ill adults, hyperinflammation plays a key role in disease progression. The clinical manifestations of SARS-CoV-2 infection among children are much less severe compared with adult patients and usually associated with a good prognosis. However, hyperinflammation in SARS-CoV-2-infected pediatric patients has been described as pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 or as Kawasaki-like disease but is still little known, and optimal management has to be defined.
