In older adults, the most common kidney biopsy diagnoses include pauci-immune crescentic glomerulonephritis, membranous nephropathy, and focal segmental glomerulosclerosis. Recently, investigators described a small series of older patients (aged 66-80 years) with acute kidney injury and a kidney biopsy demonstrating tubular basement membrane (TBM) immune deposits of polytypic immunoglobulin G (IgG) and C3, acute tubular injury, and tubulointerstitial inflammation. They identified a circulating antibody against kidney tubular low-density lipoprotein (LDL) receptor-related protein 2 (LRP2; also known as megalin) in patients' sera and colocalization of LRP2 with IgG in TBM deposits...

Background Plasma glucose levels provide the cornerstone of diabetes evaluation, and so it is crucial that clinical laboratories provide accurate and reliable plasma glucose results. To prevent in vitro glycolysis, citrate is used. Here, we present the first study on the 75-g oral glucose tolerance test (OGTT) using the currently available new citrate-containing tubes in liquid and granular forms and the previous sodium fluoride (NaF) for the diagnosis of carbohydrate metabolism disorders and gestational diabetes mellitus (GDM) according to the American Diabetes Association (ADA) guidelines...

BACKGROUND: Hantavirus infections are endemic worldwide, and its incidence in Europe has been steadily increasing. In Western Europe, hantavirus infections are typically caused by Puumala hantavirus and cause nephropathia epidemica (NE), a mild form of haemorrhagic fever with renal syndrome. Up to now, there is only little data about the course of acute NE in children, but it has been suggested that hantavirus infections take a lighter course in children when compared to adults. We performed a retrospective analysis of adults and children diagnosed with acute NE in two counties in South-Western Germany to investigate if there are differences in the course of the disease...

Background: The core features of autism spectrum disorder (ASD) are easily recognizable in non-structured clinical and real-life situations. The features are often difficult to capture in structured laboratory settings, and the results from tests do not necessarily reflect symptom severity. We investigated neurophysiological processing in the passive parts of a cued Go-NoGo task, using the active parts of the test as a comparator. Methods: Forty-nine adolescents diagnosed with ASD and 49 typically developing (TD) adolescents (age 12-21 years) were included...

BACKGROUND: Staphylococcus argenteus and Staphylococcus schweitzeri, previously known as divergent Staphylococcus aureus clonal lineages, have been recently established as novel, difficultly delimitable, coagulase-positive species within the S.aureus complex. Methicillin-resistant S.argenteus are known from Australia and U.K.. Knowledge on their epidemiology, medical significance and transmission risk is limited and partly contradictory, thus, hampering definitive recommendations. There is mounting evidence that S...

BACKGROUND: Diabetes mellitus (DM) is common among tuberculosis (TB) patients and often undiagnosed or poorly controlled. We compared point of care (POC) with laboratory glycated haemoglobin (HbA1c ) testing among newly diagnosed TB patients to assess POC test accuracy, safety and acceptability in settings in which immediate access to DM services may be difficult. METHODS: We measured POC and accredited laboratory HbA1c (using high-performance liquid chromatography) in 1942 TB patients aged 18 years recruited from Peru, Romania, Indonesia and South Africa...

BACKGROUND: Brucella is high-consequence pathogen and one of the most common seen laboratory- acquired infection pathogens. Quick and accurate detection of the pathogen will be of great important to reducing laboratory- acquired infection. Traditional biomedical reaction based method is time consumption, and mass spectrometry based method greatly reduces time consumption in pathogen identification. In the case presented here, we shared our experience in identification of Brucella directly from positive blood culture with mass spectrometry based method...

In France, the frequency of premature rupture of the membranes (PROM) is 2%-3% before 37 weeks' gestation (level of evidence [LE] 2) and less than 1% before 34 weeks (LE2). Preterm delivery and intrauterine infection are the major complications of preterm PROM (PPROM) (LE2). Prolongation of the latency period is beneficial (LE2). Compared with other causes of preterm delivery, PPROM is associated with a clear excess risk of neonatal morbidity and mortality only in cases of intrauterine infection, which is linked to higher rates of in utero fetal death (LE3), early neonatal infection (LE2), and necrotizing enterocolitis (LE2)...

BACKGROUND: Early initiation of antiretroviral therapy (eiART) can improve clinical outcomes for persons with HIV and reduce onward transmission risk. Baseline drug resistance testing (bDRT) can inform regimen selection upon subsequent treatment initiation. We examined the uptake of eiART and bDRT within 3 months and 30 days of HIV diagnosis. METHODS: We analyzed a population-based sample from the San Francisco Department of Public Health HIV/AIDS Case Registry of newly-diagnosed HIV/non-AIDS individuals between 2001 and 2015 who received care at publicly-funded facilities (N = 3,124)...

Worldwide, sickle cell disease (SCD) poses a significant public health concern. It causes recurrent morbidity, and premature death is a distinct possibility, especially in Nigeria, which bears half the world's burden of SCD patients. Nigeria has yet to establish a newborn screening program; consequently, most affected children are diagnosed between one and three years of age when a health problem arises. Parents are unprepared to identify SCD and seek comprehensive management early enough for the best outcome...

BACKGROUND: Primary central nervous system lymphoma (PCNSL) is a rare subtype of extranodal lymphoma. Despite established clinical prognostic scoring such as that of the Memorial Sloan Kettering Cancer Center (MSKCC) and the International Extranodal Lymphoma Study Group, outcome prediction needs to be improved. Several studies have indicated an association between changes in hematologic laboratory parameters with patient outcomes in PCNSL. We sought to assess the association between hematological parameters and overall survival (OS) in patients with PCNSL...
