Healthcare utilization following spinal cord injury: Objective findings from a regional hospital registry

Objective: The purpose was to describe the prevalence and characteristics of healthcare utilization among individuals with spinal cord injury (SCI) from a Level I trauma center.

Design: Retrospective data analysis utilizing a local acute trauma registry for initial hospitalization and merged with the Dallas-Fort Worth Hospital Council registry to obtain subsequent health care utilization in the first post-injury year.

Setting: Dallas, TX, USA.

Participants: Six hundred and sixty four patients were admitted with an acute traumatic SCI from January 2003 through June 2014 to a Level I trauma center. Fifty five patients that expired during initial hospitalization and 18 patients with unspecified SCI (defined by ICD-9 with no etiology or level of injury specified) were not included in the analysis, leaving a final sample of 591.

Outcome Measures: Data included demographic and clinical characteristics, charges, and healthcare utilization.

Results: Mean age was 46.1?years (±18.9?years), the majority of patients were male (74%), and Caucasian (58%). Of the 591 patients, 345 (58%) had additional inpatient or emergency healthcare utilization accounting for 769 additional visits (median of 3 visits per person). Of the 769 encounters, 534 (69%) were inpatient and 235 (31%) were emergency visits not resulting in an admission. The most prevalent ICD-9 codes listed were pressure ulcer, neurogenic bowel, neurogenic bladder, urinary tract infection, fluid electrolyte imbalance, hypertension, and tobacco use.

Conclusion: Individuals with SCI experience high levels of healthcare utilization which are costly and may be preventable. Increasing our understanding of the prevalence and causes for healthcare utilization after acute SCI is important to target preventive strategies.     

Male circumcision for HIV prevention in India: emerging viewpoints and practices of health care providers

A compelling case for promoting male circumcision (MC) as an intervention for reducing the risk of heterosexually acquired HIV infection was made by dissemination of the results of three studies in Africa. The WHO/UNAIDS recommendation for MC for countries like India, where the epidemic in concentrated in high-risk groups, advocates MC for specific population groups such as men at higher risk for HIV acquisition. A multicentre qualitative study was conducted in four geographically distinct districts (Belgaum, Kolkata, Meerut and Mumbai) in India during June 2009 to June 2011. Two categories of health care providers: Registered Healthcare Providers (RHCPs) and traditional circumcisers were interviewed by trained research staff who had received master's level education using interview guides with probes and open-ended questions. Respondents were selected using purposive sampling. A comparative analysis of the perspectives of the RHCP vs. traditional circumcisers is presented. Representatives of both categories of providers expressed the need for Indian data on MC. Providers feared that promoting circumcision might jeopardize/undermine the progress already made in the field of condom promotion. Reservation was expressed regarding its adoption by Hindus. Behavioural disinhibition was perceived as an important limitation. A contrast in the practice of circumcision was apparent between the traditional and the trained providers. MC should be mentioned as a part of comprehensive HIV prevention services in India that includes HIV counselling and testing, condom distribution and diagnosis and treatment of sexually transmitted infections. It should become an issue of informed personal choice rather than ethnic identity.     

Thrombocytopenia in children with malaria–A study from coastal Karnataka,India

ObjectiveTo study the occurrence and severity of thrombocytopenia in children with malaria.MethodsIt was a retrospective study, done at Fr Muller Medical College Hospital Mangalore, in Karnataka, India. Data regarding all positive cases of malaria < 15 years admitted in the hospital between January 2010 to June 2011 were obtained. Patients were further assessed for thrombocytopenia and its severity. Data were analysed by Chi square test using SPSS version 13.0.ResultsA total of 159 cases were included in the study with a mean age of presentation of 9 years. Plasmodium vivax was identified in 106 (66%) patients while Plasmodium falciparum in 26 (16%) and mixed infection in 27 (18%) patients. Thrombocytopenia was observed in 113 (71%) cases, of which 35 (31%) cases had mild, 49 (43%) cases moderate and 29 (26%) cases had severe thrombocytopenia. Thrombocytopenia was equally found in vivax and falciparum infection with no significant difference in severity between vivax and falciparum species.ConclusionsThrombocytopenia is frequently seen in malaria and it is not dependent on type of malaria. In any acute febrile illness, thrombocytopenia should alert one to the possibility of malaria.     

Hypolipidemic activity of a hydroalcoholic extract of Cyperus scariosus Linn. root in guinea pigs fed with a high cholesterol diet

Lipid-lowering and antioxidant activities of a hydroalcoholic extract of Cyperus scariosus Linn. root（HCS） were evaluated in guinea pigs fed with a high cholesterol diet. Serum lipid profile（total cholesterol, triglycerides, LDL-C, VLDL-C, and HDL-C）, atherogenic indices and serum enzymes（ALT, AST, ALP, LDH, and CK-MB） were performed in each group at 0 days and at the end of 60 days. Histological study of liver and kidney was done in groups 1, 2, 5, 6 and 7. The total phenolic and flavonoid content in HCS and its antioxidant activity were evaluated by the DPPH assay. Both doses of HCS decreased serum lipid profile and atherogenic indices（P 〈 0.05）. HCS has lipid lowering, immunosuppressive and antioxidant properties, and mays have value in atherosclerosis prevention. The higher dose of HCS also reduced serum AST, ALP, and LDH levels and rosuvastatin increased AST and ALP levels（P 〈 0.05）. Histology of the liver showed decreased lipid accumulation and improvement in hepatocytes in HCStreated animals. The antioxidant activity of HCS may be responsible for its lipid lowering and cytoprotective action. HCS had significant lipid lowering and antioxidant activity, which; may be due to the phenolic compounds. HCS may be a safe and cost effective alternative to current statin therapy for patients with dyslipidaemia.     

Productivity,Organic Carbon and Residual Soil Fertility of Pigeonpea–Wheat Cropping System Under Varying Tillage and Residue Management

Conservation agriculture improves productivity and soil quality, but most of the research results are only confined to the rice–wheat system. Hence, a long term field experiment was conducted at Indian Agricultural Research Institute, New Delhi during 2008–2009 to 2011–2012 on a sandy loam soil to study the effect of tillage and crop establishment techniques, and residue management practices on system productivity, residual nutrient status, microbial biomass carbon, microbial biomass nitrogen and enzymatic activities under a pigeonpea–wheat cropping system. It was observed that zero tillage gave 5.4 and 2.3 % higher pigeonpea and wheat yield, respectively, over conventional tillage. Similarly, it resulted in 9.6 and 4.9 % higher Kjeldahl N and extractable K, respectively and the plots under zero tillage had 20.6, 8.0 and 6.1 % higher dehydrogenase and acid and alkaline phosphatase activities, respectively, over conventional tillage. Application of crop residue at 3 t/ha provided 14.3 and 34.4 % higher pigeonpea and wheat grain yield, respectively, over no residue. Further, organic C, Kjeldahl N and Olsen’s P in soil were enhanced by 7.4, 6.9 and 7.5 %, respectively, due to residue compared to no residue plots. Combined application of pigeonpea + wheat residue at 3 t/ha resulted in higher dehydrogenase (20.9 µg triphenylformazan/g/h), β-glucosidase (145 µg p-nitrophenol/g/h), and acid phosphatase activities (24.5 µg p-nitrophenol/g/h) than the single application of wheat or pigeonpea residue in either season or no residue control.     

Vascular endothelial growth factor as a marker of disease activity in neurotuberculosis

Vascular endothelial growth factor (VEGF) is a potent angiogenesis mediator. Scant reports are available defining the role of VEGF in active and inactive tubercular meningitis (TBM) with no studies on brain tuberculoma. We quantified VEGF levels by enzyme linked immunoassay (ELISA) in cerebrospinal fluid (CSF) and serum in 20 cases each with active and inactive TBM as well as 22 cases of intraparenchymal tuberculoma. VEGF expression and microvessel angiogenesis quantification was done in 7 cases where tuberculomas were excised. Significantly increased VEGF levels in CSF were found in active TBM cases (106.0+/-50.0 pg/ml) compared to inactive TBM cases (14.7+/-10.0 pg/ml) (p<0.001). Mean serum VEGF levels in active TBM, inactive TBM and tuberculoma were 694.93+/-820.66 pg/ml, 499.61+/-238.33 pg/ml and 541.0+/-389.0 pg/ml, respectively. Immunohistochemical staining of excised tuberculoma demonstrated high expression of VEGF in granulomatous areas with intense positivity in inflammatory mononuclear cells, Langhan's giant cells as well as reactive astrocytes and fibrocytes. A strong positive correlation was observed between microvessel density and VEGF expression. Serial decrease in serum VEGF levels was observed with increasing duration of therapy in tuberculoma. We conclude that increased CSF and serum VEGF levels are a measure of activity of the disease in neurotuberculosis and its gradual decrease over a period of time is probably an indicator of therapeutic response.     

Nonhemolytic antibody-induced loss of erythrocyte surface antigen

Transfusion of red blood cells (RBCs) into patients with anti-donor RBC antibodies (crossmatch-incompatible transfusion) can result in lethal antibody-mediated hemolysis. Less well appreciated is the ability of anti-RBC antibodies to specifically remove their target antigen from donor RBCs without compromising cell survival or adversely affecting the transfusion recipient. In an effort to elucidate the mechanistic details of this process, we describe the first animal model of nonhemolytic antibody-induced RBC antigen loss. RBCs from transgenic mHEL mice express surface hen egg lysozyme (HEL) as a transmembrane protein. Transfusion of mHEL RBCs into mice immunized with HEL results in selective loss of HEL antigen from donor RBCs without affecting other blood group antigens or reducing the circulatory life span of the transfused RBCs. While this process does not require the presence of a spleen, it requires both anti-RBC immunoglobulin G (IgG) antibodies and the FcgammaIII receptor. These studies provide mechanistic insight into the phenomenon of antigen loss during incompatible transfusion in humans.
