Statistical Analysis of Malignant Brain Neoplasms (ICD-10: C71) in the Lower Silesia Region of Poland in the Years 2006-2012
Abstract:
It is crucial for the society, the government and the medical community to retrieve the full and reliable statistical information on malignant brain neoplasms (C71-C71.9 ICD-10) to adjust the medical financing, staff and equipment properly. In order to retrieve information useful for public health policies, data from the years 2006-2012 concerning relevant cases registered by the Polish public healthcare insurance provider Narodowy Fundusz Zdrowia in Lower Silesia region of Poland (NFZ) and by the Polish national neoplasms registry Krajowy Rejestr Nowotworow (KRN) were analyzed. The number of new malignant brain neoplasms cases registered by the KRN has risen slightly in the years 2006-2012. At the same time the number of cases reported by the NFZ rose dynamically, which means a significant increase in medical care intensity, and thus also workload on the medical facilities and stuff associated with the care for grossly the same amount of brain malignant ...
A Role for in Vitro Disease Models in the Landscape of Preclinical Cardiotoxicity and Safety Testing
Abstract:
Drug-induced cardiotoxicity is one of the predominant reasons for drug attrition and withdrawals. This is of critical concern when potentially cardiotoxic drugs are administered to individuals with inherited arrhythmogenic cardiac diseases or with metabolic diseases such as obesity and diabetes, which are key risk factors for cardiovascular diseases. Pathophysiological alteration prevalent under such conditions can alter or exacerbate cardiotoxic responses. The growing incidence of obesity, diabetes and metabolic syndrome subject a significant percentage of the population to drug treatments, thereby augmenting their risk for drug-induced cardiovascular toxicity. Hence, screening for drug-induced cardiotoxicity early in the preclinical stages of drug development, by using appropriate human disease models, can be effective in ensuring safety in clinical trials and preventing late stage and post-marketing drug withdrawals owing to cardiotoxicity. The advent of human ...
Expression of Estrogen Receptor β in Hypothalamic Stem Cells
Abstract:
Neural stem cell activity at least partially accounts for the postweaning development of the sexually dimorphic nucleus of the preoptic area (SDN-POA) and estrogen selectively mobilizes neural stem cells in the 3rd ventricle stem cell niche (3VSCN). Here, we examined the expression of estrogen receptor β (ERβ) in the SDN-POA and the 3VSCN. A subset of cells within the SDN-POA--delineated with or without calbindin D28K (CB28)-immunoreactivity (ir)--exhibited ERβ-ir. The ependymal cells that expressed nestin within the 3VSCN also expressed ERβ. Interestingly, a few proliferating (Ki67 positive) cells within the 3VSCN and the hypothalamic parenchyma, including the SDN-POA, displayed ERβ-ir. In parallel, a subset of cells in the subventricular zone was double-labeled with nestin and ERβ or Ki67 and ERβ while the subgranular zone exhibited few such double-labeled cells. ERβ is expressed in hypothalamic stem cells that may regulate cell regenerative c...
Venous Thromboembolism after Orthopaedic Surgery – How Long is the Patient at Risk?
Abstract:
Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in hospital with orthopaedic surgery already an established risk factor. This study aims to establish the length of time that a patient is at risk of sustaining a VTE post orthopaedic surgery. A retrospective case series of all patients who underwent orthopaedic surgery between 2010 and 2014 whom re-presented with a VTE within one year of their initial operation. Demographic, operative and clinical information was obtained in order to identify potential risk factors. 53 patients were identified as having a VTE within one year of discharge. The majority (63.4%) underwent lower limb arthroplasty. 29% of the cohort had either a family or ...
Mycosis Fungoides Presenting as a Pigmented Purpuric Dermatosis in a Renal Transplanted Patient
Abstract:
Cutaneous lymphoma after organ transplantation is rare and its diagnosis may be delayed by both atypical clinical manifestations and failure to consider it in the differential diagnosis. Beside skin-directed therapy for the stage, immunosuppression reduction is also important for disease control. We describe a clinical case of mycosis fungoides after renal transplantation and discuss the therapeutic options.
Increased Level of Lactate Dehydrogenase Correlates with Disease Growth in Algerian Children with Lymphoma
Abstract:
This study aimed to evaluate the relation of Lactate dehydrogenase (LDH) levels with stage of the disease and it role in monitoring tumor response to therapy in lymphoma patients. LDH levels were evaluated on 65 diagnosed Algerian children and compared to healthy control. Our results revealed that LDH levels were significantly higher in untreated children with both hodgkin’s and non hodgkin’s lymphomas compared to control. Moreover, it was observed that the higher is the stage of disease, the more serum LDH level will be. However, there was a significant fall in serum LDH activity by completion of the chemotherapeutic courses.
Vitamin D Status in Diabetes Mellitus: Comparison Between Outpatients and Inpatients
Abstract:
Vitamin D (25(OH)D) status has been extensively evaluated in different populations and care settings. A negative relationship between glycated hemoglobin (HbA1c) and serum 25(OH)D levels in outpatients with diabetes has been reported, while data about 25(OH)D status in inpatients with diabetes are inconsistent. The aim of the study was to evaluate 25(OH)D levels in a large series of inpatients with type 1 and type 2 diabetes and in an age-, sex-, serum creatinine-, and HbA1c-matched group of outpatients with diabetes. After the preliminary exclusion of patients with confounding factors, 540 subjects with diabetes were retrospectively evaluated in a 1:1 matched case-control study between inpatients and outpatients.
Multivariate Analysis of Noise, Socioeconomic and Sociodemographic Factors and Their Association with Depression on Borough Level in the City State of Hamburg, Germany
Abstract:
The objective of this first part of our study was to investigate associations of road traffic noise, socioeconomic and -demographic risk factors, and health access on depression on borough level. We investigated in a large metropolis associations between prevalence rates of depression per borough (n = 67 boroughs) in all age groups (excluding the age group of 0–17 years) using health claims data (year 2011) and the variables “social deprivation” and “number of family members”, which were obtained from a previously conducted principal component analysis, and by using multivariate regression model. Additionally, the proportion of borough area affected by noise > 65 db(A) and physician density used as a surrogate parameter for health access were considered as potentially associated factors for depression. The results demonstrated that depression might be associated with increasing social borough deprivation. ...
Relationship Between Inflammatory Infiltrate Canine Mammary Carcinomas.
Abstract:
The mammary tumor is one of the most common cancer in female dogs and, at the present days, there is a big focus on the study of the relation between this kind of tumor in animals and the cells that stay around them, like the inflammatory cells. The objective of this study was to evaluate and show where the inflammatory cells stay in simple mammary carcinomas in female dogs by immunohistochemistry. Samples of simple mammary carcinomas (tumor group; n=26) and mammary gland samples without tumor (control group; n=18) were submitted to immunohistochemical analysis for the detection of T lymphocytes, macrophages, plasma cells and the MHC-II molecule. The mast cells were evaluated by the histochemical technique (toluidine blue). Lymphocytes, macrophages and mast cells were observed distributed in the tumor stroma. MHC-II was detected in tumor cells and in the inflammatory infiltrate. Plasma cells predominated in the peritumoral stroma. Macrophages differed significantl...
Shotgun Label-Free Proteomic Analyses of the Oyster Parasite Perkinsus Marinus
Abstract:
Perkinsus marinus is an intracellular parasitic protozoan that is responsible for serious disease epizootics in marine bivalve mollusks worldwide. Despite all available information on P. marinus genomics, more baseline data is required at the proteomic level. Our aim was to study the proteome profile of in vitro cultured P. marinus isolated from oysters Crassostrea spp. using a label-free shotgun UDMSE approach. A total of 4073 non-redundant proteins were identified across three biological replicates with stringent identification. Proteins specifically related to adaptive survival, cell recognition, antioxidants, regulation of apoptosis and others were detected. Important virulence factors of P. marinus were identified including serine protease and iron-dependent superoxide dismutase. Other proteins with involvement in several pathogens invasion strategies were rhoptries, serine-threonine kinases, and protein phosphatases. Interestingly, peptides corresponding to ...
