The maturation of hypothalamo-pituitary-gonadal (HPG) axis causes the onset of puberty, which stimulates the development of secondary sex characteristics and changes in the size and composition of the body. Furthermore, the size of the thyroid gland increases and its function also changes as an adaptation to the requirements of the transformation of child to an adult. It has also been reported that the thyroid hormones including thyroxin (T4) and triiodothyronine (T3) have a f...

Introduction: Elevated intraocular (vitreous) leptin is implicated in proliferative diabetic retinopathy. The source of vitreous leptin is uncertain and it could be derived from systemic leptin. However we showed that leptin (ob) mRNA is present in rat retina, suggesting that retinal tissue could also be a source of intraocular leptin. The present investigation quantified ob mRNA in human retinal tissue obtained from diabetic and control cadavers. In a parall...

We describe two unrelated men with a previously unreported combination of tumours. The first patient developed a right-sided testicular teratoma at the age of 25 years treated with orchidectomy. He went on to develop a left-sided seminoma at the age of 35 years, treated with orchidectomy followed by prophylactic para-aortic radiotherapy (30 Gy in 15 fractions). At the age of 48 years he developed a nodule in the left lobe of thyroid (AC4/Thy4 on FNA) treated with hemithyroidec...

We report a case of a well 40 year old gentleman who self-referred for confirmation of diagnosis of diabetes. On further history he had been informed by other healthcare professionals the possibility of diabetes based on his elevated fasting serum glucose of 13.8 mmol/L and HbA1c of 81mmol/mol with no osmotic symptoms. His triglyceride was also elevated at 12.26 with rather variable compliance to statin. Examination of all systems were unremarkable, however on neck examination...

Puberty, a crucial biological process, ends up in sexual maturation, reproductive capability and adult body size. It is controlled by hypothalamo–pituitary–gonadal axis (HPG), where hypothalamus synthesizes and secretes gonadotropin releasing hormone, which stimulates the adenohypophysis to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH causes formation of sperms and LH stimulates production of testosterone (T). Puberty needs an intact H...

Background: The prevalence of obesity associated comorbidities, such as Type 2 Diabetes(T2D) and hypertension, continues to rise globally. Our study aimed to describe the long-term effects on blood pressure management in individuals with T2D post bariatric surgery in a single centre prospective observational cohort study in North-West England.Methods: We undertook a 10-year prospective cohort study on people who underwen...

Background: Bariatric surgery (BS) results in metabolic pathway recalibration. When major metabolic change occurs, blood protein components have a key role and can be altered significantly. We set out to identify potential biomarkers of change in plasma following BS in people achieving remission of type 2 diabetes mellitus (T2DM).Methods: Longitudinal analysis was performed on serum samples from 10 individuals who all achieved remission of T2DM following...

Background: Bariatric surgery (BS) can have significant effects on multiple body systems and has been an effective intervention for morbid obesity, improving many comorbid medical conditions that are associated with mental health and cognitive dysfunction. It was previously shown that cognitive impairment was partly reversible in obese patients after BS [1], however, the effects of BS on proteins associated to central nervous system (CNS) still unknown. We evaluated if there a...

Aims: We used sequential window acquisition of all theoretical fragment ion spectra Mass Spectrometry (SWATH-MS) to identify proteins acting as markers of remission of type 2 diabetes (T2DM) in patients who lost weight after bariatric surgery.Background: Bariatric surgery results in remission of T2DM in up to 80% of patients. The mechanisms underpinning are largely unknown. N-acetylmuramoyl-L-alanine amidase (PGLRYP2) is an immune response enzyme that br...

Background: Male sexual dysfunction is common in obesity with complex underlying mechanisms. Testosterone replacement has often been initiated in clinical practice in the presence of sexual dysfunction and male obesity-associated secondary hypogonadism. The benefits to sexual functioning, however, are not well documented. The aims of the study were to investigate the relationship between sexual function and hypogonadism in severe obesity and to understand the impact of bariatr...
