Humanising and optimising HIV health care for refugees and asylum seekers.

Displaced populations living with HIV, including refugees and asylum seekers, face substantial challenges across various regions globally. The intersection of forced migration and HIV presents both shared challenges and region-specific differences. Key issues include little access to health care, pervasive stigma, discrimination, and disruptions in the continuity of HIV care.

Interventions to ensure access to and continuity of HIV care for international migrants: an evidence synthesis.

International migrants, especially those belonging to key populations, face a considerable HIV burden. However, continuity of HIV care for this group is often challenged along the migration route. We assess the available evidence on the existing interventions that aim to strengthen community and health systems to ensure the continuity of HIV care for international migrants.

Frequency of Major Transmitted Integrase Resistance in Poland Remains Low Despite Change in Subtype Variability.

With the widespread use of integrase inhibitors and the expanding use of long-acting cabotegravir in both pre-exposure prophylaxis and antiretroviral treatment, molecular surveillance on the transmission of integrase resistance has regained clinical significance. This study aimed to determine the frequency of INSTI-transmitted drug resistance mutations (DRMs) among treatment-naïve individuals in Poland from 2016 to 2023. INSTI resistance was analyzed in 882 antiretroviral treatment-naïve individuals using Sanger sequencing.

Cardiovascular Risk in People Living with Human Immunodeficiency (HIV) Viremia Suppression in a Young, Mid-Eastern European Population - Preliminary Study.

In-hospital mortality during the wild-type, alpha, delta, and omicron SARS-CoV-2 waves: a multinational cohort study in the EuCARE project.

Background: Investigating outcomes of hospitalised COVID-19 patients throughout the pandemic is crucial to understand the impact of different SARS-CoV-2 variants. We compared 28-day in-hospital mortality of Wild-type, Alpha, Delta, and Omicron variant infections. Whether the difference in risk by variant varied by age was also evaluated.

Phylodynamic evolution of HIV-1 A6 sub-subtype epidemics in Poland.

The human immunodeficiency virus type 1 (HIV-1) A6 sub-subtype is highly prevalent in Eastern Europe. Over the past decade, the dissemination of the A6 lineage has been expanding in Poland. The recent Russian invasion of Ukraine may further escalate the spread of this sub-subtype.

Unveiling the Heart of the Matter: Echocardiographic Insights into Diastolic Function and Left Ventricular and Atrial Changes in HIV Patients with Controlled Viremia.

Background: People living with human immunodeficiency virus (HIV) (PLWH) have increased risk of developing diastolic dysfunction (DD) and heart failure with preserved ejection fraction (EF). In this observational study, we evaluated DD and left ventricular hypertrophy (LVH) in PLWH receiving antiretroviral therapy (ART) with undetectable viremia.

Methods: We conducted an observational study.

VEGFR and DPP-IV as Markers of Severe COVID-19 and Predictors of ICU Admission.

The pathophysiology of the severe course of COVID-19 is multifactorial and not entirely elucidated. However, it is well known that the hyperinflammatory response and cytokine storm are paramount events leading to further complications. In this paper, we investigated the vascular response in the pathophysiology of severe COVID-19 and aimed to identify novel biomarkers predictive of ICU admission.

Comparison of clinical course of Mpox among HIV-negative and HIV-positive patients: A 2022 cohort of hospitalized patients in Central Europe.

Mpox has become the most significant orthopoxviral infection among humans. Since May 2022, there has been a multicountry outbreak of mpox across six continents. Retrospective observational cohort study of 94 patients with probable or confirmed mpox of whom 86.

EuCARE-hospitalised study protocol: a cohort study of patients hospitalised with COVID-19 in the EuCARE project.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), can lead to hospitalisation, particularly in elderly, immunocompromised, and non-vaccinated or partially vaccinated individuals. Although vaccination provides protection, the duration of this protection wanes over time. Additional doses can restore immunity, but the influence of viral variants, specific sequences, and vaccine-induced immune responses on disease severity remains unclear.

EuCARE-POSTCOVID Study: a multicentre cohort study on long-term post-COVID-19 manifestations.

Background: Post-COVID-19 condition refers to persistent or new onset symptoms occurring three months after acute COVID-19, which are unrelated to alternative diagnoses. Symptoms include fatigue, breathlessness, palpitations, pain, concentration difficulties ("brain fog"), sleep disorders, and anxiety/depression. The prevalence of post-COVID-19 condition ranges widely across studies, affecting 10-20% of patients and reaching 50-60% in certain cohorts, while the associated risk factors remain poorly understood.

Artificial neural network based prediction of the lung tissue involvement as an independent in-hospital mortality and mechanical ventilation risk factor in COVID-19.

Introduction: During COVID-19 pandemic, artificial neural network (ANN) systems have been providing aid for clinical decisions. However, to achieve optimal results, these models should link multiple clinical data points to simple models. This study aimed to model the in-hospital mortality and mechanical ventilation risk using a two step approach combining clinical variables and ANN-analyzed lung inflammation data.

Clinical Perspective on Human Immunodeficiency Virus Care of Ukrainian War Refugees in Poland.

Background: The Russian invasion of Ukraine forced migration for safety, protection, and assistance. Poland is the primary sheltering country for Ukrainian refugees, providing support including medical care, which resulted in the rapid ∼15% increase in the number of followed-up people with human immunodeficiency virus (HIV) (PWH) in the country. Here, we present the national experience on HIV care provided for refugees from Ukraine.
