Retinopathy and the Risk of Cardiovascular Disease in Patients With Chronic Kidney Disease (from the Chronic Renal Insufficiency Cohort Study). - The American journal of cardiology
Patients with chronic kidney disease (CKD) experience other diseases such as cardiovascular disease (CVD) and retinopathy. The purpose of this study was to assess whether retinopathy predicts future CVD events in a subgroup of the participants of the Chronic Renal Insufficiency Cohort (CRIC) study. In this ancillary investigation, 2,605 participants of the CRIC study were invited to participate, and nonmydriatic fundus photographs were obtained in 1,936 subjects. Using standard protocols, presence and severity of retinopathy (diabetic, hypertensive, or other) and vessel diameter caliber were assessed at a central photograph reading center by trained graders masked to study participant's information. Patients with a self-reported history of cardiovascular disease were excluded. Incident CVD events were adjudicated using medical records. Kidney function measurements, traditional and nontraditional risk factors, for CVD were obtained. Presence and severity of retinopathy were associated with increased risk of development of any CVD in this population of CKD patients, and these associations persisted after adjustment for traditional risk factors for CVD. We also found a direct relation between increased venular diameter and risk of development of CVD; however, the relation was not statistically significant after adjustment for traditional risk factors. In conclusion, the presence of retinopathy was associated with future CVD events, suggesting that retinovascular pathology may be indicative of macrovascular disease even after adjustment for renal dysfunction and traditional CVD risk factors. Assessment of retinal morphology may be valuable in assessing risk of CVD in patients with CKD, both clinically and in research settings.Copyright © 2015 Elsevier Inc. All rights reserved.

2D and 3D similarity landscape analysis identifies PARP as a novel off-target for the drug Vatalanib. - BMC bioinformatics
Searching for two-dimensional (2D) structural similarities is a useful tool to identify new active compounds in drug-discovery programs. However, as 2D similarity measures neglect important structural and functional features, similarity by 2D might be underestimated. In the present study, we used combined 2D and three-dimensional (3D) similarity comparisons to reveal possible new functions and/or side-effects of known bioactive compounds.We utilised more than 10,000 compounds from the SuperTarget database with known inhibition values for twelve different anti-cancer targets. We performed all-against-all comparisons resulting in 2D similarity landscapes. Among the regions with low 2D similarity scores are inhibitors of vascular endothelial growth factor receptor (VEGFR) and inhibitors of poly ADP-ribose polymerase (PARP). To demonstrate that 3D landscape comparison can identify similarities, which are untraceable in 2D similarity comparisons, we analysed this region in more detail. This 3D analysis showed the unexpected structural similarity between inhibitors of VEGFR and inhibitors of PARP. Among the VEGFR inhibitors that show similarities to PARP inhibitors was Vatalanib, an oral "multi-targeted" small molecule protein kinase inhibitor being studied in phase-III clinical trials in cancer therapy. An in silico docking simulation and an in vitro HT universal colorimetric PARP assay confirmed that the VEGFR inhibitor Vatalanib exhibits off-target activity as a PARP inhibitor, broadening its mode of action.In contrast to the 2D-similarity search, the 3D-similarity landscape comparison identifies new functions and side effects of the known VEGFR inhibitor Vatalanib.
Estimating the cost of TB and its social impact on TB patients and their households. - Public health action
Illness often poses a significant financial burden on individuals and their households, and tuberculosis (TB) is no exception. Although TB treatment is free in Nigeria, patients are likely to incur costs due to multiple visits during treatment. The purpose of this study was 1) to examine the health-seeking behaviour of TB patients and the costs borne by TB patients in Nigeria, and 2) to assess the social impact of TB disease on TB patients and their families/households. Of 260 TB patients surveyed, the majority (74.7%) were aged between 20 and 49 years. TB patients expended an average of US$52.02 (N = 8323.58, at the rate of US$1 = N = 160) per person on all visits associated with diagnosis and receipt of diagnostic test results. Overall, households experienced a shortfall of about US$57.30 (N = 9174.72) or 24.9% of income loss due to TB illness. Further analysis revealed that 9.7% of TB patients relied on children of school age or below to finance the costs of TB illness.
HIV-TB co-infection in children: associated factors and access to HIV services in Lagos, Nigeria. - Public health action
Human immunodeficiency virus (HIV) and tuberculosis (TB) are the leading causes of death from infectious disease worldwide. The World Health Organization estimates that the prevalence of HIV among children with TB in moderate to high prevalence countries ranges between 10% and 60%. This study aimed to determine the access to HIV services of HIV-TB co-infected children.A retrospective review of data of children diagnosed with TB in Lagos State, Nigeria from 1 January 2012 to 31 December 2013.A total of 1199 children aged between 0 and 14 years were diagnosed with TB. Of 1095 (91.3%) who underwent testing for HIV, 320 (29.2%) were HIV seropositive. The male-to-female ratio of HIV-TB positive outcomes was 1:0.9. Of the 320 HIV-TB co-infected children, 57 (17.8%) were aged <1 year, 86 (26.9%) 1-4 years and 186 (58.1%) 5-14 years; 186/320 (58.1%) began cotrimoxazole preventive therapy (CPT), and 151 (47.2%) were put on antiretroviral treatment (ART). ART uptake was not significantly higher in facilities where HIV-TB services were co-located (P > 0.05).The uptake of CPT and ART was low. There is a need to intensify efforts to improve access to HIV services in Lagos State, Nigeria.
Patients with idiopathic recurrent miscarriage show higher levels of DR+ activated T-cells that are less responsive to mitogens. - Journal of reproductive immunology
In 50% of recurrent miscarriages (RM) the cause remains unknown and standardized immunological diagnosis and treatment of idiopathic RM (iRM) is yet not established. In this prospective case-control study, out of 220 RM patients screened, 97 iRM patients were identified and compared to 26 healthy controls without a previous pregnancy or blood transfusion in order to identify deregulated immunological parameters. Blood levels of lymphocyte subpopulations, cytokines and neopterin were determined by FACS, ELISA, and Luminex technique. Lymphocyte function was studied by in-vitro lympocyte proliferation tests. As compared to controls, patients had significantly higher proportions of activated CD3+DR+, CD4+DR+ and CD8+DR+ lymphocytes, elevated levels of neopterin and a lower in-vitro proliferation of lymphocytes (all p<0.05). Within the iRM patients higher proportions of CD3+DR+ T-lymphocytes correlated with higher proportions and absolute numbers of CD4+DR+ and CD8+DR+ T-lymphocytes and lower CD16+CD56+ NK-cells. Further, it was associated with lower absolute numbers of CD19+ B-lymphocytes, CD3+CD25+ T-lymphocytes and CD45+ total lymphocytes (all p<0.05). In addition we found decreased in-vitro lymphocyte proliferation in iRM patients with high CD3+DR+ T-lymphocytes (p<0.05). In summary patients with iRM showed increased activated T-cells that are less responsive to mitogens in-vitro. The inverse relationship of increased DR but decreased CD25 expression on CD3+ T-cells and the decreased in-vitro proliferation characterize an immunological disorder with similarities to T-cell exhaustion in patients with HIV and cancer. These abnormalities potentially contribute to the pathogenesis of iRM and might be a target for future immunomodulatory therapies.Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

DilataciÓn endoscÓpica biliar transpapilar con balÓn para el tratamiento de la colÉdoco litiasis. - Revista de gastroenterologia del Peru : organo oficial de la Sociedad de Gastroenterologia del Peru
To evaluate the efficacy and safety of transpapillary papilloplasty in patients with choledocholithiasis.All endoscopic retrograde cholangiopancreatography (ERCP) procedures performed at Hospital Ana Costa, in the city of Santos, Brazil, over the last five years were retrospectively evaluated using the hospital's information database. The success of the procedure and complications due to residual calculi, pancreatitis, bleeding and perforation were evaluated.From January 2010 to May 2014, 1860 ERCP procedures were performed. Fifty-five patients were evaluated here. Their ages ranged from 12 to 98 years (mean, 66.3; standard deviation, 19.34; median, 71). Thirty-two patients (58.2%) were women. Sixteen (29.1%) presented giant choledocholithiasis, with calculi larger than 12 mm. Twenty-seven (49.1%) had mul-tiple choledocholithiasis.In view of the therapeutic efficacy and low complication rate among our patients, we can conclude that endoscopic papilloplasty is a safe and effective method for endoscopic treatment of choledocolithiasis in selected cases.
Comparative Analysis of Linear and Angular Measurements on Digital Orthopantomogram with Calcaneus Bone Mineral Density. - Journal of clinical and diagnostic research : JCDR
Bone remodeling is a continuous and complex process which occurs throughout life. Radiomorphometric and radioangular indices on the orthopantomogram are the predictors of bone remodeling associated with mandible. Bone mineral density is the amount of calcified tissue in a certain volume of the bone.Fifty normal healthy individuals within the age range of 25-55 years were included in the study. Linear measurements including mandibular cortical width (MCW) and panoramic mandibular index (PMI); and angular measurements including mandibular angle (MA) and antegonial angle (AGA) were recorded. Quantitative ultrasound bone mineral density (BMD) scan of the heel bone (calcaneus) of the same patient were also performed.In our study, for both males and females, antegonial angle (AGA) had highest correlation with calcaneus bone mineral density. In the age group of less than 35 years, PMI in males, and AGA in females had highest correlation. In the age range of more than 35 years, MA in males and AGA in females had highest correlation.There is a correlation between the mandibular bone remodelling changes and calcaneal bone mineral density in case of elder subjects and thus these parameters may be used as an inexpensive alternative screening method to assess the bone mineral density and identify individuals at risk for osteoporosis and fractures and also for dental treatment planning.
