Article Abstract
Background: Infections in critically ill patients are the main reasons for a lack of therapeutic success and increased mortality in intensive care units (ICUs). There have been many analyses of the incidence of infections in ICUs; however, no large studies of this kind have been conducted either in Poland or in Eastern and Central Europe.
Objectives: The aim of the research was to undertake a one-day study of the prevalence of infections in ICUs in Warszawa and the Mazovian region of Poland.
Material And Methods: A prospective questionnaire survey analysis - a one-day prevalence study of infections - was carried out on June 25, 2014, in 28 ICUs in Poland.
Results: Among 205 ICU patients (193 adults and 12 children), 134 infections were found in 101 patients (99/193 adults (51.30%) and 2/12 children (16.70%)), and bacterial colonization in 19/205 (9.3%) patients. In 66.42% of the cases, more than 1 site of infection was diagnosed. On the day of the study, 75.40% of the diagnosed infections had positive microbiological results. The most frequent were respiratory tract infections (53.73%), wound infections (18.65%) and bloodstream infections (14.92%). Most of the infections (64.10%) were caused by Gram-negative bacteria (GN), followed by Gram-positive bacteria (GP; 31.80%) and fungi (4.10%). The most frequently reported GN microorganisms were Enterobacteriaceae (44.7%). Methicillin-resistant Staphylococcus aureus (MRSA) infections were found in 8.80% of the patients. Antibiotics were administered to 75.60% of the adult patients, in 69.20% as targeted treatment. Mechanical ventilation, central vein catheterization and urinary bladder catheterization were used in 67.80%, 85.85% and 94.63% of the patients, respectively.
Conclusions: On the day of the study, more than half of the patients had infections, mostly from GN bacteria. Respiratory tract infections were the main type found. In about 2/3 of the patients, antibiotics were administered, mainly as targeted therapy.

The effects of missing data due to study dropout on longitudinal analysis inference using outcome-dependent sampling.

Background: Existing longitudinal cohort study data and associated biospecimen libraries provide abundant opportunities to efficiently examine new hypotheses through retrospective specimen testing. Outcome-dependent sampling (ODS) methods offer a powerful alternative to random sampling when testing all available specimens is not feasible or biospecimen preservation is desired. For repeated binary outcomes, a common ODS approach is to extend the case-control framework to the longitudinal setting.

Background: In recent years, social media has emerged as a pivotal tool in implementation science efforts to address the HIV epidemic. Engaging community partners is essential to ensure the successful and equitable implementation of social media strategies. There is a notable lack of scholarship addressing the operational considerations for studies using social media strategies in community-partnered HIV research.

Background: Scrub typhus (ST), also known as tsutsugamushi disease, is a common febrile vector-borne illness in South Korea, transmitted by trombiculid mites infected with Orientia tsutsugamushi, with rodents serving as the main hosts. Although vector-borne diseases like ST require both a One Health approach and a spatiotemporal perspective to fully understand their complex dynamics, previous studies have often lacked integrated analyses that simultaneously address disease dynamics, vectors, and environmental shifts.
Objective: We aimed to explore spatiotemporal trends, high-risk areas, and risk factors of ST by simultaneously incorporating host and environmental information.
Candidate Cytokine Biomarkers for the Diagnosis of Ocular- and Neurosyphilis.

Purpose: To describe differences in the expression of selected host biomarkers, by analysing the aqueous humour (AH), cerebrospinal fluid (CSF) and serum of patients with ocular syphilis, both with and without neurosyphilis and HIV infection, to support the diagnosis of ocular syphilis.
Methods: A prospective observational descriptive study was conducted at Tygerberg Academic Hospital in Cape Town, South Africa, from February 1, 2018, to January 31, 2021. The study included all patients aged 18 years or older who presented to the eye clinic with ocular syphilis, provided they had a positive serum Treponema pallidum antibodies (TPA) test, an RPR titre of ≥ 8 and confirmed ocular inflammation.
