Diagnostic Value of Microbial Cell-free DNA Sequencing for Suspected Invasive Fungal Infections: A Retrospective Multicenter Cohort Study.

Background: An early diagnosis and treatment of invasive fungal disease (IFD) is associated with improved outcome, but the moderate sensitivity of noninvasive diagnostic tests makes this challenging. Invasive diagnostic procedures such as bronchoalveolar lavage (BAL) have a higher yield but are not without risk. The detection and sequencing of microbial cell-free DNA (mcfDNA) may facilitate a noninvasive diagnosis.

Iron metabolism is prospectively associated with insulin resistance and glucose intolerance over a 7-year follow-up period: the CODAM study.

Objectives: Several markers of iron metabolism have been associated with insulin resistance (IR) and type 2 diabetes mellitus in cross-sectional studies. However, prospective data on these associations are scarce, and it is currently unclear in which tissues iron metabolism may contribute to IR. Therefore, we investigated whether markers of iron metabolism were associated with IR in muscle, liver, and adipocytes, and with glucose intolerance over a 7-year follow-up period.

Complement factor 3 is associated with insulin resistance and with incident type 2 diabetes over a 7-year follow-up period: the CODAM Study.

Objective: Immune dysregulation can affect insulin resistance (IR) and β-cell function and hence contribute to development of type 2 diabetes mellitus (T2DM). The complement system, as a regulator of immune and inflammatory homeostasis, may be a relevant contributor therein. However, longitudinal studies focusing on complement as a determinant of T2DM and IR are scarce.

Activated complement factor 3 is associated with liver fat and liver enzymes: the CODAM study.

Background: The complement system may be involved in the pathogenesis of alcoholic and nonalcoholic liver disease, although studies in humans are scarce. For this reason, we investigated whether circulating levels of activated complement factor 3 (C3a) were associated with hepatic steatosis and hepatocellular damage.

Materials And Methods: Plasma C3a, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT) were determined in 523 individuals (61% men, age 59 ± 7 years).

Diabetes mellitus at the time of diagnosis of cirrhosis is associated with higher incidence of spontaneous bacterial peritonitis, but not with increased mortality.

DM (diabetes mellitus) is present in 20-40% of patients with liver cirrhosis, but its prognostic impact is unclear. Therefore, in the present study, we investigated whether the presence of DM in patients with cirrhosis was associated with increased mortality, and/or with increased incidence of SBP (spontaneous bacterial peritonitis). We reviewed medical and laboratory data of 230 patients with cirrhosis from the period 2001-2011, for whom data were complete in n=226.

Iron metabolism is associated with adipocyte insulin resistance and plasma adiponectin: the Cohort on Diabetes and Atherosclerosis Maastricht (CODAM) study.

Objective: Adipocyte insulin resistance (IR) is a key feature early in the pathogenesis of type 2 diabetes mellitus (T2DM), and although scarce, data in the literature suggest a direct role for iron and iron metabolism-related factors in adipose tissue function and metabolism. Serum ferritin and transferrin were shown to be associated with muscle insulin resistance (IR) and T2DM, but little is known about the role of iron metabolism on adipose tissue. We therefore investigated whether markers of iron metabolism were associated with adipocyte IR and plasma adiponectin.

Low-grade inflammation and insulin resistance independently explain substantial parts of the association between body fat and serum C3: the CODAM study.

Objective: To investigate the role of low-grade inflammation and insulin resistance (HOMA2-IR) in adiposity-related increases in serum complement factor 3 (C3). Although C3 has been linked to type 2 diabetes and cardiovascular diseases, and C3 levels are closely related to body fat, the underlying mechanisms explaining this association are still unknown.

Methods: Adiposity measures (including BMI, waist circumference (WC), sagittal diameter and several skinfolds), HOMA2-IR and markers of inflammation (hs-CRP, IL-6, SAA, haptoglobin, ceruloplasmin, sICAM-1) were determined in 532 individuals (62% men, mean age 59±6.

[Diabetes mellitus and cirrhosis of the liver: a prognostically unfavourable combination].

We conducted a literature search to determine the prognostic effect of diabetes in patients with cirrhosis of the liver. We also searched for evidence on diagnosis and treatment of diabetes in these patients. Insulin resistance occurs in obese patients with cirrhosis due to non-alcoholic steatohepatitis, but also develops in patients with alcoholic or viral cirrhosis.

[Low back pain and MRI-abnormalities: atypical polymyalgia rheumatica].

A 64-year-old man was admitted to hospital with increasing low back pain, radiating to his upper legs. MRI of the lumbar spine showed inflammatory lesions of vertebrae L3-L5, after which the patient was treated with flucloxacilline for 6 weeks. However, he did not improve and the pain became more extensive.

[Thrombophlebitis of the leg: diagnosis and treatment by the general practitioner].

We reviewed the literature for the association between superficial vein thrombosis (SVT) and venous thromboembolism (VTE) and for evidence of treatment of SVT with low-molecular-weight heparin (LMWH). There is some evidence for an association between SVT and VTE. This association seems stronger for proximal SVT as compared with distal SVT.
