Introduction: The insulin-like growth factor-I receptor (IGF-IR) plays a key role in regulating growth, survival and invasion of several human malignancies including prostate cancer. In prostate cancer cells, the IGF-IR expression is upregulated by androgens through a nongenotropic signaling unresponsive to antiandrogens and requiring AMP-response element-binding protein (CREB) activation. This mechanism sensitizes cells to the proliferative and protumor effects of IGF-I. Metf...

Bone metabolism can be measured indirectly with specific biochemical markers. Desoxypyridinolin (DPD) is a derivate of hydroxypyridinium, which is discharged by bone resorption and is totally excreted urinary. A further marker of collagen resorption is the c-terminal telopeptide of collagen type I, which is liberated to blood circulation within the bone’s degradation and undergoes renal elimination. The aim of our investigation was to look after a correlation of these par...

Background: The ACE I/D polymorphism of the ACE gene, associated with cardiovascular risk and athletic performance, accounts for half the variation in resting ACE. DD subjects have the greatest, ID intermediate, and II subjects the lowest serum ACE. Exercise stimulates the renin-angiotensin system, producing a rise in angiotensin II. 3 small (n=6-8) lab studies suggest serum ACE does not change with exercise, despite a rise in angiotensin II, whereas 2 other studies have demon...

Background: During childhood, growth hormone (GH) doses are usually calculated using total body weight (TBW). This may result in inappropriately high doses in obese children where the intravascular compartment does not increase in proportion with the increase in weight, as the volume of distribution of GH is consistent with the majority of the drug being distributed in the total body water compartment.Methods: Single centre, retrospective cohort study of...

Introduction: The clinical relevance of low IGF-I levels, caused by cranial radiotherapy, in adult childhood cancer survivors has not been studied extensively. We evaluated whether IGF-I is a useful marker for altered body composition and growth hormone deficiency in this group.Methods: We analyzed retrospective data from 610 adult childhood cancer survivors, retrieved from the late effects clinic. Median age at diagnosis was 6 years (interquartile range...

Introduction: Diabetic nephropathy (DN) is one of the most serious chronic complications of diabetes mellitus characterized by persistent albuminuria, raised arterial blood pressure, a lowered glomerular filtration rate, and high-risk of cardiovascular morbidity and mortality. The vascular genes (Angiotensin-converting enzyme) ACE, and (aldosterone synthase) CYP11B2 are involved in alterations in vascular endothelium, and are suggested to play a role in the susceptibi...

Objective: The finding of new biomarkers is needed to have an early diagnosis of breast cancer. In this study we evaluated serum levels of carboxylated osteocalcin (OC) and uncarboxylated osteocalcin(UcOC), CRP as a diagnostic biomarker for breast cancer.Design and methods: Blood samples of 39 women with newly diagnosed breast cancer with stage I were obtained before surgery and 39 age and BMI matched health women were selected as controls.<p class="...

Background: Advanced small cell lung cancer (SCLC), extra-pulmonary neuroendocrine carcinoma (EP-NEC) and pancreatic adenocarcinoma (PDA) are rapidly progressive cancers characterized by unbridled replication stress. Patients with these malignancies possess dismal prognoses with limited options after initial first-line chemotherapy. These tumors rely on the integrity of DNA damage repair pathways to ensure genomic stability. The ataxia telangiectasia and Rad3-related (ATR) pro...

Background: Early glycaemic control improves long-term outcomes in children with Type I diabetes. The NICE target for children with T1DM is HbA1c ≤ 48 mmol/mol. 2018 data from our newly diagnosed patients (pre-QI) demonstrated mean HbA1c 50 mmol/mol at 3 months and 62 mmol/mol at 12 months.Aims and methods: Our aim is to improve average blood glucose levels at day 28 post diagnosis and achieve a median HbA1c of <48 mmol/mol at 3 and 12 months p...

Background: Improved knowledge of the range of anomalies encountered in DSD may improve our understanding of the underlying aetiology. However, given the rarity of these conditions, thorough analysis of congenital anomalies in DSD has not previously been possible.Aims: To discover the frequency of congenital anomalies in DSD, and to identify patterns of anomalies within specific conditions.Methods: 1050 registered cases on The I-DS...
