: Out of 39.9 million adults living with HIV in 2022, 20 million were women. Despite bearing a significant burden, women remain underrepresented in clinical trials, including those for antiretroviral treatments (ART).

Mortality Attributable to Bloodstream Infections Caused by Different Carbapenem-Resistant Gram-Negative Bacilli: Results From a Nationwide Study in Italy (ALARICO Network).

Background: Our aim was to analyze mortality attributable to carbapenem-resistant (CR) gram-negative bacilli (GNB) in patients with bloodstream infections (BSIs).

Methods: Prospective multicentric study including patients with GNB-BSI from 19 Italian hospitals (June 2018-January 2020). Patients were followed-up to 30 days.

In-vitro NET-osis induced by COVID-19 sera is associated to severe clinical course in not vaccinated patients and immune-dysregulation in breakthrough infection.

Since neutrophil extracellular traps formation (NET-osis) can be assessed indirectly by treating healthy neutrophils with blood-derived fluids from patients and then measuring the NETs response, we designed a pilot study to convey high-dimensional cytometry of peripheral blood immune cells and cytokines, combined with clinical features, to understand if NET-osis assessment could be included in the immune risk profiling to early prediction of clinical patterns, disease severity, and viral clearance at 28 days in COVID-19 patients. Immune cells composition of peripheral blood, cytokines concentration and in-vitro NETosis were detected in peripheral blood of 41 consecutive COVID-19 inpatients, including 21 mild breakthrough infections compared to 20 healthy donors, matched for sex and age. Major immune dysregulation in peripheral blood in not-vaccinated COVID-19 patients compared to healthy subjects included: a significant reduction of percentage of unswitched memory B-cells and transitional B-cells; loss of naïve CD3CD4CD45RA and CD3CD8CD45RA cells, increase of IL-1β, IL-17A and IFN-γ.

Clinical characteristics and predictors of death among hospitalized patients infected with SARS-CoV-2 in Sicily, Italy: A retrospective observational study.

Since late December 2019, severe acute respiratory syndrome coronavirus 2 has spread across the world, which resulted in the World Health Organization declaring a global pandemic. Coronavirus disease 2019 (COVID-19) presents a highly variable spectrum with regard to the severity of illness. Most infected individuals exhibit a mild to moderate illness (81%); however, 14% have a serious disease and 5% develop severe acute respiratory distress syndrome (ARDS), requiring intensive care support.

A new call for influenza and pneumococcal vaccinations during COVID-19 pandemic in Italy: A SIP/IRS (Italian Respiratory Society) and SITA (Italian Society of Antiinfective therapy) statement.

Influenza and pneumococcal disease represent a well-known burden on healthcare systems worldwide, as well as they still have an attributed morbidity and mortality, especially in elderly individuals and vulnerable populations. In the context of the ongoing pandemic of COVID-19, a series of considerations in favor of extensive influenza and pneumococcal vaccination campaign are emerging, including a possible reduction of hospital extra burden and saving of sanitary resources. In addition, recent studies have suggested that prior vaccinations towards non SARS-CoV-2 pathogens might confer some protection against COVID-19.

Therapeutic strategies for severe COVID-19: a position paper from the Italian Society of Infectious and Tropical Diseases (SIMIT).

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.

Acute acalculous cholecystitis on a COVID-19 patient: a case report.

Introduction: We report an extremely rare case of acute acalculous cholecystitis on a COVID-19 patient. In our knowledge, this is the first report of laparoscopic cholecystectomy performed on a COVID-19 patient.

Presentation Of Case: A COVID-19 patient was diagnosed with acute acalculous cholecystitis and a multidisciplinary team decided to perform a percutaneous transhepatic biliary drainage (PTBD) as the first treatment.

Transcriptional landscape of SARS-CoV-2 infection dismantles pathogenic pathways activated by the virus, proposes unique sex-specific differences and predicts tailored therapeutic strategies.

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) has posed a serious threat to global health. As no specific therapeutics are yet available to control disease evolution, more in-depth understanding of the pathogenic mechanisms induced by SARS-CoV-2 will help to characterize new targets for the management of COVID-19. The present study identified a specific set of biological pathways altered in primary human lung epithelium upon SARS-CoV-2 infection, and a comparison with SARS-CoV from the 2003 pandemic was studied.

Is Transient Elastography Needed for Noninvasive Assessment of High-Risk Varices? The REAL Experience.

Introduction: The Baveno VI consensus guidelines and an expanded algorithm suggest that transient elastography (TE) and platelet (PLT) count can be used to identify patients with cirrhosis who can avoid esophagogastroduodenoscopy (EGD). The primary aims of this study were to assess the ability of a simple algorithm, which uses only laboratory parameters, to predict medium/large esophageal varices (EV) in patients with hepatitis C virus (HCV) and cirrhosis from the Rete Sicilia Selezione Terapia-HCV (RESIST-HCV) cohort and to compare the performance of the algorithm with Baveno VI and Expanded Baveno VI criteria. The secondary aim was to assess the role of TE in ruling out large EV.

Epidemiology and Microbiology of Skin and Soft Tissue Infections: Preliminary Results of a National Registry.

Skin and soft tissue infections (SSTIs) represent a wide range of clinical conditions characterized by a considerable variety of clinical presentations and severity. Their aetiology can also vary, with numerous possible causative pathogens. While other authors previously published analyses on several types of SSTI and on restricted types of patients, we conducted a large nationwide surveillance programme on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients.

Incidence of Hepatocellular Carcinoma in Patients With HCV-Associated Cirrhosis Treated With Direct-Acting Antiviral Agents.

Background & Aims: Studies have produced conflicting results of the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C virus-associated cirrhosis treated with direct-acting antivirals (DAAs). Data from clinics are needed to accurately assess the occurrence rate of HCC in patients with cirrhosis in the real world.

Methods: We collected data from a large prospective study of 2,249 consecutive patients (mean age = 65.

Neurobrucellosis: diagnostic and clinical management of an atypical case.

Brucellosis is the most common zoonosis in the world and it is caused by ingestion of foods contaminated by Brucella spp. that is able to avoid the immune system and can involve every organ system. The bacteria may affect the Central Nervous System (CNS) directly or using phagocytic cells with the way of the "Trojan Horse Model".

A Double-Blind Placebo-Controlled Trial of Liquid Thyroxine Ingested at Breakfast: Results of the TICO Study.

Background: Levothyroxine (LT4) is the recommended treatment for millions of hypothyroid patients. Current guidelines recommend that LT4 tablets be taken in a fasting state, but inability to adhere to this often leads to poor therapy compliance.

Methods: A randomized, double-blind, placebo-controlled, crossover trial was conducted in previously untreated hypothyroid patients randomly assigned to receive an oral solution of LT4 either at least 30 minutes before breakfast or directly at breakfast time.

[Management of infections from cardiac implantable electronic devices: recommendations from a study panel].

Cardiac Implantable Electronic Device (CIED) infections are an emerging clinical issue. There are no national recommendations on the management of these infections, also due to the limited number of dedicated and high quality clinical studies. Therefore, researchers from southern Italian centres have decided to share the clinical experience gathered so far in this field and report practical recommendations for the diagnosis and treatment of adult patients with CIED infection or endocarditis.

Thyroidal effect of metformin treatment in patients with polycystic ovary syndrome.

Objective: Metformin is widely used for the treatment of type 2 diabetes. Growing evidence supports the beneficial effects of metformin also in patients with polycystic ovary syndrome (PCOS). It was recently reported that metformin has a TSH-lowering effect in hypothyroid patients with diabetes being treated with metformin.

[Saccharomyces cerevisiae fungemia associated with multifocal pneumonia in a patient with alcohol-related hepatic cirrhosis].

Saccharomyces cerevisiae is usually considered non-pathogenic and has rarely been reported as a cause of fungemia in immunocompromised patients, especially those admitted to an intensive care unit or those affected by acquired immune deficiency syndrome or under immunosuppressive treatment. In all described cases the use of probiotic yeast has been given as the main risk factor. We report a case of S.

Serum leptin levels are higher in females affected by frontotemporal lobar degeneration than Alzheimer's disease.

Frontotemporal lobar degeneration (FTLD) includes different heterogeneous conditions, mainly characterised by personality changes, along with cognitive deficits in language and executive functions. Movement disorders are variably represented. Behavioural disturbances constitute the core feature of FTLD, and eating disorders represent one of the most distinguishing symptoms between FTLD and Alzheimer's disease (AD).
