Introduction: The COVID-19 pandemic has promoted an intensive investigation into the pathophysiological mechanisms of SARS-CoV-2 infection, risk factors, and its impact on disease severity. Vitamin D has generated significant attention for its potential role in viral prevention and immune defense due to its pleiotropic functions, including immunomodulation and antimicrobial effects. This study aimed to assess serum 25(OH)D3 levels in patients with COVID-19 compared to those with other viral respiratory infections and to evaluate associations of vitamin D levels with symptomatology, clinical characteristics, presence of comorbidities and laboratory investigation.

Introduction: This paper examines the use of local antibiotic therapy in one-stage septic revision surgery for late periprosthetic joint infections (PJIs). This case study suggests that morselized bone allografts impregnated with antibiotics in powder form are a preferable alternative to polymethyl methacrylate (PMMA) because they can generate higher local antibiotic concentrations. Current research also recommends using vancomycin and aminoglycosides as the preferred choice of antibiotics, as they may have low diffusion in tissues when administered intravenously, but are effective when administered locally.

infection (CDI) is one of the main causes of morbidity associated with antibiotic use, producing both healthcare-associated infections and community infections. This study aims to describe the epidemiological characteristics, the clinical outcomes, previous antibiotic exposure, and other risk factors of hospitalized patients with CDI in a tertiary infectious disease hospital in Bucharest, Romania. We performed a descriptive analysis based on four-year surveillance data, collected in a tertiary infectious disease hospital in Bucharest, Romania.

Pulmonary abscess is a rare but serious condition in pediatric patients, caused by severe pulmonary infection that leads to tissue destruction and necrosis. It can be classified as primary or secondary depending on the cause. Establishing an etiology in pediatric pulmonary abscesses is challenging, underscoring the essential role of advanced imaging techniques, such as computed tomography, in achieving an accurate diagnosis and differentiating among various conditions that may mimic lung abscess.

Background: Histological findings of infective endocarditis (IEs) in mechanical valves present a complex diagnostic challenge owing to the lack of a precise definition. This ambiguity is further complicated by the natural degenerative processes that occur in the mechanical valves over time. Consequently, pathologists and clinicians face significant difficulties in distinguishing between genuine infective processes and the normal wear and tear of mechanical valves.

Background/objectives: We aimed to characterize the fibrosis following COVID-19 pneumonia, using quantitative analysis, after three months and subsequently, after two years of patients' release from the hospital, and to identify the risk factors for pulmonary fibrosis.

Methods: We performed a retrospective, observational cohort study on 420 patients with severe forms of COVID-19. For all patients, we registered demographic, inflammatory and biochemical parameters, complete blood count and D-dimers; all patients underwent three computed tomography scans (at admittance, at 3 months and at 2 years).

Objectives: Our objective was to explore how women living with HIV aged ≥40 years perceive their care in relation to their HIV infection, comorbidities, and menopausal health and to evaluate the extent to which the care they receive meets their expectations, comparatively across World Health Organization (WHO) European regions.

Methods: We conducted a cross-sectional survey (May-December 2023) among women living with HIV aged ≥40 years from the WHO European region. Five dimensions of care were assessed: content of care, information, relationship with caregiver, organization of care, and patients' rights and privacy, in addition to management of non-HIV comorbidities and menopause.

Article Synopsis
  • The study assessed the safety and tolerability of bulevirtide (BLV), a new treatment for chronic hepatitis delta (CHD), by analyzing data from three clinical trials involving 269 patients.
  • The findings indicated that certain adverse events, such as increased bile acid levels and injection-site reactions, were more common with BLV compared to a control group, but serious side effects were minimal and did not lead to treatment discontinuation.
  • Overall, BLV was deemed safe and well tolerated over 48 weeks of therapy in patients with CHD, showing promise as an effective treatment option.

Monitoring the HIV epidemic in Romania has proven challenging due to many factors, including the reluctance of newly diagnosed patients to disclose relevant epidemiological aspects during the clinical interview, such as sexual orientation or the existence of previous issues with injectable drug usage. We propose in this study a molecular approach to mitigate this problem with the help of bioinformatic tools, such as cluster analysis of phylogenetic trees. Both a maximum likelihood estimation, as implemented with FastTree, and a Bayesian approach, as used in BEAST, have been applied to our data set of 312 HIV subtype F1 gene sequences.

Tuberculosis is the primary cause of death due to infection in the world. Identification of in sputum is a diagnostic test, which can be used in screening programs-especially in countries with a high incidence of tuberculosis-to identify and treat those persons with the highest risk of disseminating the infection. We previously developed an algorithm which is able to automatically detect mycobacteria on tissue; in particular, our algorithm identified acid-fast bacilli on tissue with 100% specificity, 95.

Introduction: is one of the associated bacteria that can cause the rare but high mortality hematological pathology known as purpura fulminans (PF) in both adults and children. Pediatric patients with PF can progress quickly to sepsis and multiorgan failure, especially immunocompromised individuals and young children. Due to the thrombotic blockage of blood arteries in PF, there is diffuse intravascular thrombosis and hemorrhagic infarction of the skin, which evolves from ecchymosis to skin necrosis, risk of limb sequelae, sepsis and fatality.

Article Synopsis
  • A survey was conducted among 32 senior clinicians across 20 European countries to understand current practices in postnatal prophylaxis (PNP) and infant feeding guidelines.
  • Twenty-three clinicians responded, revealing that all countries use risk stratification for PNP, but methods and regimens widely differ, with zidovudine being the most commonly used drug.
  • There is significant variation in guidelines regarding infant feeding for babies born to HIV-positive parents, highlighting the need for harmonization in policies to minimize HIV transmission and support informed feeding choices.

  • * There is a noted but poorly defined connection between GD and cutaneous keratinocyte carcinomas, specifically non-melanoma skin cancers (NMSCs), with very few studies highlighting this relationship between 1983 and 2024.
  • * GD has been misdiagnosed as various NMSCs, and understanding this connection could provide insights into its underlying mechanisms, possibly reclassifying GD as a unique syndrome.

There is existing controversy regarding the efficacy of tigecycline (TG) in treating complicated urinary tract infections (cUTIs) because of its pharmacokinetic concerns. We present three patients with cUTIs caused by carbapenem-resistant gram-negative (GN) pathogens successfully treated with high-dose tigecycline (HDT)-based regimens, as cefiderocol and aztreonam were not available in our country. The first case describes a 67-year-old patient with diabetes, prostate cancer, and double J ureteral stenting who was hospitalized with a febrile, complicated urinary tract infection (cUTI).
