Iron deficiency (ID) is a common manifestation of inflammatory bowel disease (IBD), arising primarily due to chronic inflammation and/or blood loss. There is no gold standard for ID diagnosis, which ...is often complicated by concomitant inflammation. Zinc protoporphyrin (ZnPP) correlates with parameters of iron homeostasis and has been identified as a promising marker for ID, irrespective of inflammation. We investigated the diagnostic performance of ZnPP in ID, iron deficiency anemia, anemia of chronic disease and mixed anemia in a cross-sectional study in 130 patients with IBD. Different parameters were compared by receiver operator characteristic (ROC) analysis as detectors of iron-restricted erythropoiesis (IRE). IRE was detected in 91 patients (70.0%); fifty-nine (64.8%) had absolute ID and 23 (25.4%) functional ID. When inflammation was present, ZnPP was a more reliable sole biomarker of IRE than MCV, transferrin saturation (TSAT) or ferritin (AUC; 0.855 vs. 0.763, 0.834% and 0.772, respectively). The specificity of TSAT was significantly lower than ZnPP when inflammation was present (38% vs. 71%, respectively). We conclude that ZnPP is a reliable biomarker of functional ID in patients with IBD and more dependable than ferritin or TSAT, which are influenced by chronic inflammation. We propose that ZnPP may also have utility in patients with other chronic diseases.
Statement of problem Edentulism in combination with chronic alveolar ridge resorption can lead to a debilitating oral state which conventional complete dentures cannot alleviate. The provision of ...anterior mandibular implants positively contributes to both function and an improved quality of life for these patients. However, individuals who could most benefit from the treatment are usually older and more likely to have or develop serious health issues. Purpose The purpose of the study was to assess the long-term success of one of the simpler implant treatments available and to consider the impact of a number of factors, including sex, age, health issues, and tobacco habits. This study also assessed the specific implant used, the Calcitek hydroxyapatite coated cylinder. Material and methods Forty-one patients who received 102 implants for mandibular overdenture retention from 1 operator between 1996 and 2002 were included in the study. Measurements were made from a series of radiographs to assess the effect of periimplant bone loss on surviving implants after a period of implant function of between 6 and 10 years. Results The loss of 1 implant lowered the survival rate to 99%. The overall annual bone loss observed was 0.16 mm/year. Individuals with a significant comorbidity exhibited a slight but significant increase in annual bone loss. Conclusions The implant system in this study performed to an acceptable level in a mixed cohort of older individuals, including those with a serious comorbidity or tobacco habit.
Disseminated intravascular coagulopathy (DIC) is a very rare outcome post endovascular repair of aortic aneurysm dissections. We present a case of a 70‐year‐old male who presented with DIC post a ...thoracic endovascular aortic repair (TEVAR) procedure due to a type 1A endoleak. Initially, the patient was treated with red blood cells and blood products; however, when failing to improve, he underwent a hybrid arch replacement. In this study, we will analyze the management of DIC post TEVAR and look at its presentation more extensively, as it is currently a topic that is poorly studied.
The endoscopically implanted duodenal–jejunal bypass liner (DJBL) is an impermeable fluoropolymer device which prevents food making contact with the proximal intestine, thus inducing weight loss and ...improvement of type 2 diabetes mellitus (T2DM). However, weight and HbA1c levels generally increase post explantation. This study investigated the safety and feasibility of early DJBL reimplantation in five patients with obesity whose glucose levels had relapsed post explantation, examining the effect of reimplantation on weight loss, BMI and T2DM management. All DJBL implantation and explantation procedures were performed without complications. Despite reduction of T2DM medications, reduction in body weight and HbA1c levels resumed after reimplantation. In conclusion, early reimplantation of DJBL appears feasible, safe and effective.
In the absence of a feasible noninvasive gold standard, iron deficiency (ID) anemia (IDA) is best measured using multiple indicators. However, the choice of an appropriate single iron biomarker for ...ID screening continues to be debated. Low hemoglobin density (LHD%) from Coulter counters has been suggested as a useful tool to detect ID. This study investigated the reliability of LHD% for the assessment of iron status in patients with inflammatory bowel disease (IBD) and IDA, anemia of chronic disease (ACD) or mixed anemia (MIX).
The study population consisted of 143 patients with IBD (aged 39.03±12.53 years, 61.5% female). Blood count, transferrin saturation, serum ferritin, and C-reactive protein were determined by routine assays. Patients with anemia were divided into 3 groups: IDA, ACD and MIX, according to specific criteria. Receiver operator characteristic (ROC) curves were constructed.
ROC analysis for LHD% in the detection of ID yielded a cutoff value of 3.8%. In anemic patients, LHD% values did not differ statistically significantly between groups (IDA, ACD, MIX) and no significant difference in LHD% values was observed between patients with IDA and ID.
These results demonstrate that LHD% is a reliable biomarker for the detection of iron deficiency in patients with IBD and anemia, regardless of whether inflammation is present. Our findings indicate that LHD% can provide added value in diagnosing iron deficiency.
During the last decade, Greece faced one of the most severe debt crises among developed countries, leading to Economic Adjustment Programs in order to avoid a disorderly default. Public expenditure ...was cut, tax rates were increased and new taxes were introduced, aiming at restoring public finances. Prominent among the latter were recurrent property taxes that had played a very minor role before the crisis. These taxes helped to boost public revenues but were hugely unpopular. The paper examines in detail their distributional impact andfinds that they led to increases in inequality and (relative) poverty. The result is stronger in the case of inequality indices that are relatively more sensitive to changes close to the bottom of the distribution and poverty indices that are sensitive to the distribution of income among the poor.
