Mechanistic regulation of inflammation inciting prostate cancer remains largely uncharacterized. Therefore, we investigated the role of c-kit/SCF pathway, which has been associated with the control of prostate carcinogenesis, in chronic prostatitis (CP) rats, and evaluated the anti-prostatitis effect of resveratrol. H&E staining was performed to identify the histopathological changes in prostates. Multiple approaches examined the expression levels of c-kit, stem cell factor (SCF), Sirt1, carcinogenesis associated proteins...

BACKGROUND: Environmental exposures are contributing factors to prostate cancer etiology, but these remain unclear. We aimed to document the associations between environmental risk factors and prostate cancer in Chinese, with special reference to bisphenol A (BPA). METHODS: We recruited 431 newly diagnosed prostate cancer cases and 402 age-matched controls from Prince of Wales Hospital in Hong Kong. We obtained each participant's clinical data and epidemiological information on chronic BPA exposure and other environmental risk factors (e...

Acute myeloid leukemia (AML) developing in patients with chronic lymphocytic leukemia (CLL) is very uncommon and usually associated with prior treatment. Acute promyelocytic leukemia (APL) accounts for a very small proportion of treatment-associated AML. So far, there has been only one reported case of APL occurring post radiation for prostate cancer in a patient with CLL. We report herein the first case of APL and CLL presenting concomitantly in an untreated patient. Evaluation of peripheral blood and bone marrow aspirate with immunohistochemistry, flow cytometry, and FISH to confirm two morphologically, molecularly and genetically distinct leukemic populations characteristic of APL and CLL is required...

OBJECTIVES: Chronic bacterial prostatitis (CBP) is the most common urological disease in patients younger than 50 years, whose long-standing symptoms could be related to an inappropriate therapeutic regimen. The objective was to analyse the sensitivity of microorganisms isolated from patients with CBP and measure the weekly antibiotic concentrations in serum, semen and urine. MATERIAL AND METHODS: For the antibiotic sensitivity study, 60 clinical isolates were included between January 2013 and December 2014 from semen samples from patients with microbiologically confirmed CBP...

BACKGROUND: Cancer-related fatigue (CRF) reduces quality of life and the activity level of patients with cancer. Cancer related fatigue can be reduced by exercise interventions that may concurrently increase muscle mass. We hypothesized that low muscle mass is directly related to higher CRF. METHODS: A total of 233 patients with advanced cancer starting palliative chemotherapy for lung, colorectal, breast, or prostate cancer were studied. The skeletal muscle index (SMI) was calculated as the patient's muscle mass on level L3 or T4 of a computed tomography scan, adjusted for height...

Curcumin, an extract from the turmeric rhizome (Curcuma longa), is known to exhibit anti-inflammatory, antioxidant, chemopreventive and antitumoral activities against aggressive and recurrent cancers. Accumulative data indicate that curcumin may induce cancer cell death. However, the detailed mechanism underlying its pro-apoptotic and anti-cancer effects remains to be elucidated. In the present study, we examined the signaling pathways triggered by curcumin, specifically, the exact molecular mechanisms of curcumin-induced apoptosis in highly metastatic human prostate cancer cells...

Chronic prostatitis (CP) with complex pathogenesis is difficult for treatment. c-kit has been associated with the control of cell proliferation of prostate cells. This study aims to evaluate the role of resveratrol, an activator of Sirt1, in regulating the expression of c-kit in CP and investigate the consequent effects on cell cycle. Rat model of CP was established through subcutaneous injections of diphtheria-pertussis-tetanus vaccine and subsequently treated with resveratrol. Hematoxylin and eosin staining was performed to identify the histopathological changes in prostates...

BACKGROUND: Infections of the genital tract are considered common causes of male fertility disorders, with a prevalence of 6-10%. Most of the affected men are asymptomatic. The diagnostic evaluation is based mainly on laboratory testing. Inconsistent diagnostic criteria have been applied to date, and this may explain the controversial debate about the role of infection and inflammation in the genital tract as a cause of infertility. The risk of an irreversible fertility disorder should not be underestimated...

BACKGROUND: Prostate cancer (PC) is a common noncutaneous malignancy in men. The incidence of PC is increasing at an alarming rate across the globe. Progression of PC is associated with elevated levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in malignant cells. Overexpression of these players is accompanied by chronic inflammation, increased angiogenesis, proliferation, migration, and inhibition of apoptosis. Moreover, their elevated circulating levels promote the disease progression from androgen-dependent to androgen-independent state...

Heart failure (HF) is a debilitating and life-threatening condition, with 5-year survival rate lower than breast or prostate cancer. It is the leading cause of hospital admission in over 65s, and these admissions are projected to rise by more than 50% over the next 25 years. Transthoracic echocardiography (TTE) is the first-line step in diagnosis in acute and chronic HF and provides immediate information on chamber volumes, ventricular systolic and diastolic function, wall thickness, valve function and the presence of pericardial effusion, while contributing to information on aetiology...

INTRODUCTION: There is no obvious criterion about kidney transplantation for patients with pretransplant malignancy. Minimum tumor-free waiting periods differ according to type of cancer, staging, site of occurrence, response to therapy, and risk of cancer recurrence. We report a case of living donor kidney transplantation (LDKT) in a patient after brachytherapy for prostate cancer. CASE REPORT: The patient was a 65-year-old man with chronic kidney disease due to chronic glomerular nephritis...

BACKGROUND: Cancer progression has been associated with altered immune cell function and activation. Neopterin, which is secreted by interferon-γ stimulated macrophages, exhibits an association with multiple cancer types and metastatic disease. Chitotriosidase, which is secreted by chronically activated macrophages and granulocyte-macrophage colony-stimulating factor stimulated neutrophils has not been studied in the setting of cancer. OBJECTIVE: The goal of this discovery study was to screen chitotriosidase for diagnostic capacity in detecting cancer and compare its operating characteristics with those of neopterin...

INTRODUCTION: Benign prostatic hyperplasia is a prevalent chronic condition with expenditures exceeding $1 billion each year. Little is known about management of patients by primary care physicians compared to urologists. We assessed changes in management after medication initiation in these two settings. METHODS: From the Chronic Condition Warehouse 5% sample of Medicare beneficiaries linked to Medicare Part D data, we defined a cohort of men, 66 to 90 years old, with initial prescriptions for alpha-blocker, 5-alpha reductase inhibitor (5-ARI), or both...

OBJECTIVE: Multiple solid cancers contain tertiary lymphoid organs (TLO). However, it is unclear whether they promote tumor rejection, facilitate tumor evasion, or simply whether they are a byproduct of chronic inflammation. We hypothesize that although chronic inflammation induces TLO formation, the tumor milieu can modulate TLO organization and functions in prostate cancer. Therefore, our study seeks to elucidate the cellular and molecular signatures in unique prostatectomy specimens from evanescent carcinoma patients to identify markers of cancer regression, which could be harnessed to modulate local immunosuppression or potentially enhance TLO function...
