OBJECTIVES: The diagnostic yield and clinical impact of image-guided core needle biopsy(ICNB) of suspected vertebral osteomyelitis in adults is heterogenous in published studies due to small sample size, indicating the need for large cohort studies. METHODS: A retrospective analysis of ICNBs was performed from 2010-2021 for patients with imaging findings consistent with vertebral osteomyelitis. For each biopsy, a series of factors were analyzed, as well as if histopathology was diagnostic of osteomyelitis and if microbiological cultures were positive...

OBJECTIVES: To evaluate the neutralizing antibody (NAbs) levels against the SARS-CoV-2 Omicron variants BF.7, BQ.1, BQ.1.1, XBB.1, and XBB.1.5 after vaccination and natural infection. METHODS: The NAbs against the different viral strains of 490 SARS-CoV-2 infected and 187 uninfected individuals in Beijing COVID-19 outbreak during December 2022 to January 2023 were analyzed. RESULTS: In uninfected individuals, limited levels of NAbs were produced against both the prototype and variant strains after two doses vaccine, but significantly increased after three or four doses vaccine...

BACKGROUND: Early isolation and care for Ebola Disease patients at Ebola Treatment Units (ETU) curb outbreak spread. We evaluated time to ETU entry and associated factors during the 2022 Sudan virus disease (SVD) outbreak in Uganda. METHODS: We included persons with RT-PCR-confirmed SVD with onset September 20-November 30, 2022. We categorized days from symptom onset to ETU entry ('delays') as short (≤2), moderate (3-5), and long (≥6); the latter two were 'delayed isolation'...

BACKGROUND: Information is scarce on clinical experiences with non-neutropenic patients with invasive fungal infection (IFI) receiving isavuconazole. We aimed to report the safety and effectiveness of this drug as a first-line treatment or rescue in real life. METHODS: A retrospective, observational multicentric study of non-neutropenic patients who received isavuconazole as an IFI treatment at 12 different university hospitals (January 2018 - 2022). All patients met criteria for proven, probable or possible IFI according to EORTC-MSG...

OBJECTIVE: To determine the incidence of mortality and its predictors among pulmonary TB (PTB) survivors treated at a rural Ugandan tertiary hospital. METHODS: We conducted a retrospective chart review of data between 2013 and 2023. We included all people that met the WHO's definition of tuberculosis cure and traced them or their next of kin to determine vital status (alive/deceased). We estimated the cumulative incidence of mortality per 1,000 population, crude all-cause mortality rate per 1,000 person-years, and median years of potential life lost (YPLL) for deceased individuals...

We report a long-term remission in candidiasis in a 57-year-old Finnish female with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) suffering from recurrent oral, esophageal, gastric, vaginal, and anal candidiasis since childhood. Candidiasis treatment with antifungal medicines fluconazole, itraconazole, posaconazole, voriconazole, caspofungin, nystatin or amphotericin-B during 2008-2021 had variable effects and intermittent development of antifungal resistance and hospital periods. The patient started using fermented lingonberry juice (FLJ) as a mouth rinse daily in April 2021...

OBJECTIVES: To investigate if SARS-CoV-2 mRNA vaccination has an impact on HIV-related viro-immunological parameters. METHODS: PWH of the VAXICONA-ORCHESTRA cohort who received ≥1 dose of SARS-CoV-2 mRNA vaccine and for whom paired measures of immuno-virological markers [Viral Load (VL), CD4, CD8 count 1 month before and after a vaccine dose (VD)] were available, were included. Paired t-test and generalized estimating equation linear regression analyses were used to study changes over ± 1 month around the VD...

BACKGROUND: Vietnam continues to have measles and rubella outbreaks following supplementary immunization activities (SIA) and routine immunization despite both having high reported coverage. To evaluate immunization activities, age-specific immunity against measles and rubella, and the number of averted Congenital Rubella Syndrome (CRS) cases, must be estimated. METHODS: Dried blood spots were collected from 2,091 randomly selected individuals aged 1-39 years. Measles and rubella virus-specific immunoglobulin G (IgG) were measured by enzyme immunoassay...

OBJECTIVES: Determine SARS-CoV-2 IgG antibody incidence over time in unvaccinated pediatric healthcare workers (pHCWs). DESIGN: Prospective longitudinal cohort of unvaccinated pHCWs measuring incidence of new infection after initial prevalence was established at 4.1% with seropositive predominance in emergency department (ED)-based pHCWs. Serum samples were collected at follow-up visits to detect new SARS-CoV-2 seropositivity. Univariate analysis was performed to estimate different incidence rates between participant demographics, job, employment location and community risk factors...

INTRODUCTION: The COVID-19 pandemic significantly changed respiratory viruses' epidemiology due to non-pharmaceutical interventions and possible viral interactions. This study investigates whether the circulation patterns of respiratory viruses have returned to pre-pandemic norms by comparing their peak timing and duration during the first three SARS-CoV-2 seasons to pre-pandemic times. METHODS: GISRS data from 194 countries (2014-2023) was analyzed for epidemic peak timing and duration, focusing on pre-pandemic and pandemic periods across both hemispheres and the intertropical belt...

OBJECTIVES: Accuracy of malaria rapid diagnostic tests is threatened by Plasmodium falciparum with pfhrp2/3 deletions. This study compares gene deletion prevalence determined by multiplex qPCR and conventional PCR (cPCR) using existing samples with clonality previously determined by microsatellite genotyping. METHODS: Multiplex qPCR was used to estimate prevalence of pfhrp2/3 deletions in three sets of previously collected patient samples from Eritrea and Peru. The qPCR was validated by multiplex digital PCR...

OBJECTIVES: In winter 2022/23 SARS-CoV-2 had developed into one of many seasonal respiratory pathogens, causing an additional burden of acute respiratory infections (ARI). While testing was still widely used, many positive tests were not reported for the official statistics. Using data from a population-based cohort, we aimed to investigate the contribution of SARS-CoV-2 to the burden of ARI. METHODS: Over 70,000 participants of the German population-based DigiHero study were invited to a questionnaire about the number and time point of ARI, and SARS-CoV-2 test results in winter 2022/23...

OBJECTIVES: To investigate the effectiveness of intravenous immunoglobulin (IVIG) as treatment for COVID-19 in immunocompromised patients. METHODS: This retrospective study investigated outcomes for immunocompromised, vaccine non-responsive, patients that between September 2022 and April 2023 received IVIG as treatment for COVID-19 in the region of Västerbotten, Sweden. We analyzed clinical data, viral load, and anti-SARS-CoV-2 IgG binding and neutralization levels of patient serum samples and IVIG production batches...

BACKGROUND: In Haematology, prophylaxis for Pneumocystis jirovecii pneumonia (PCP) is recommended for patients undergoing hematopoietic stem cell transplantation and in selected categories of intensive chemotherapy for hematological malignancies. Trimethoprim-sulfamethoxazole (TMP-SMX) is the recommended first-line agent, but its use is not straightforward. Inhaled pentamidine is the recommended second-line agent but aerosolized medications were discouraged during respiratory virus outbreaks, especially during the COVID-19 pandemic, in view of potential contamination risks...
