Consultation outcomes for musculoskeletal conditions at two community health centres in Cape Town

Objectives: To compare the proportion of patients with documented diagnoses and management plans when they presented with musculoskeletal complaints at two community health centres (CHCs) using two models of care: one with a rheumatology outreach service and the other with none. Secondly, to describe the profile of patients with rheumatoid arthritis (RA) who attended the CHC with the outreach service. Design: Cross-sectional. Setting: Heidelberg Community Health Centre and Vanguard Community Health Centre, Cape Town. Subjects: A group of 59 patients at each CHC were compared regarding engagement of their musculoskeletal complaints by doctors and clinical nurse practitioners (CNPs). Secondly, 24 RA patients who attended Heideveld CHC were profiled. Results: A comparison of the “overall engagement” between the two CHCs [risk difference (RD) -0.06, 95% confidence interval (CI): -0.17–0.05, odds ratio (OR) 0.79, 95% CI: 0.51–1.24, chi-square 0.82, p-value 0.36] was not significantly different. Comparison between doctors (RD -0.05, 95% CI: -0.05–0.08, OR 0.80, 95% CI: 0.46–1.40, chi-square 0.41, p-value 0.52) was also not significantly different. The comparison between the CNPs at the two CHCs was statistically significant (RD 0.30, 95% CI: 0.14–0.45, OR 8.37, 95% CI: 1.05–66.60, Fisher's exact test 0.01), but the CI around OR was large. Patients with RA had a mean age of 60 years, an average of two co-morbidities and an average of three annual clinic visits. Eighty- three per cent resided in the drainage area of the clinic. Conclusion: There was no significant difference in engagement between the CHCs. The potential that CNPs seemed to show of being positively influenced by the outreach service should be further researched. Patients with RA had co- morbidities that required management at primary healthcare level

IgG autoantibody to brain beta tubulin III associated with cytokine cluster-II discriminate cerebral malaria in central India

We investigated the significance of these self-reactive antibodies in clinically well-defined groups of P. falciparum infected patients manifesting mild malaria (MM), severe non-cerebral malaria (SM), or cerebral malaria (CM) and in control subjects from Gondia, a malaria epidemic site in central India using quantitative immunoprinting and multivariate statistical analyses. A two-fold complete-linkage hierarchical clustering allows classifying the different patient groups and to distinguish the CM from the others on the basis of their profile of IgG reactivity to brain proteins defined by PANAMA Blot. We identified beta tubulin III (TBB3) as a novel discriminant brain antigen in the prevalence of CM. In addition, circulating IgG from CM patients highly react with recombinant TBB3. Overall, correspondence analyses based on singular value decomposition show a strong correlation between IgG anti-TBB3 and elevated concentration of cluster-II cytokine (IFNγ, IL1β, TNFα, TGFβ) previously demonstrated to be a predictor of CM in the same populatio

Self-Reactivities to the Non-Erythroid Alpha Spectrin Correlate with Cerebral Malaria in Gabonese Children

BACKGROUND: Hypergammaglobulinemia and polyclonal B-cell activation commonly occur in Plasmodium sp. infections. Some of the antibodies produced recognize self-components and are correlated with disease severity in P. falciparum malaria. However, it is not known whether some self-reactive antibodies produced during P. falciparum infection contribute to the events leading to cerebral malaria (CM). We show here a correlation between self-antibody responses to a human brain protein and high levels of circulating TNF alpha (TNFα), with the manifestation of CM in Gabonese children. METHODOLOGY: To study the role of self-reactive antibodies associated to the development of P. falciparum cerebral malaria, we used a combination of quantitative immunoblotting and multivariate analysis to analyse correlation between the reactivity of circulating IgG with a human brain protein extract and TNFα concentrations in cohorts of uninfected controls (UI) and P. falciparum-infected Gabonese children developing uncomplicated malaria (UM), severe non-cerebral malaria (SNCM), or CM. RESULTS/CONCLUSION: The repertoire of brain antigens recognized by plasma IgGs was more diverse in infected than in UI individuals. Anti-brain reactivity was significantly higher in the CM group than in the UM and SNCM groups. IgG self-reactivity to brain antigens was also correlated with plasma IgG levels and age. We found that 90% of CM patients displayed reactivity to a high-molecular mass band containing the spectrin non-erythroid alpha chain. Reactivity with this band was correlated with high TNFα concentrations in CM patients. These results strongly suggest that an antibody response to brain antigens induced by P. falciparum infection may be associated with pathogenic mechanisms in patients developing CM

Evaluation of spent coffee obtained from the most common coffeemakers as a source of hydrophilic bioactive compounds

The main hydrophilic antioxidant compounds (3-, 4-, and 5-monocaffeoylquinic and 3,4-, 3,5-, and 4,5-dicaffeoylquinic acids, caffeine, and browned compounds, including melanoidins) and the antioxidant capacity (Folin-Ciocalteu, ABTS, DPPH, Fremy's salt, and TEMPO) were evaluated in Arabica and Robusta spent coffee obtained from the preparation of coffee brews with the most common coffeemakers (filter, espresso, plunger, and mocha). All spent coffee grounds, with the exception of those from the mocha coffeemaker, had relevant amounts of total caffeoylquinic acids (6.22-13.24 mg/g of spent coffee), mainly dicaffeoylquinic acids (3.31-5.79 mg/g of spent coffee), which were 4-7-fold higher than in their respective coffee brews. Caffeine ranged from 3.59 to 8.09 mg/g of spent coffee. The antioxidant capacities of the aqueous spent coffee extracts were 46.0-102.3% (filter), 59.2-85.6% (espresso), and <42% (plunger) in comparison to their respective coffee brews. This study obtained spent coffee extracts with antioxidant properties that can be used as a good source of hydrophilic bioactive compounds

Enzymatic synthesis of some O-beta-D-digalactosyl glycopeptides, using beta-D-galactosidase.

International audienceDisaccharide-peptide conjugates were obtained in yields of 30-50% from o-nitrophenyl beta-D-galactopyranoside by employing beta-D-galactosidase from E. coli as catalyst. Two series of beta-D-galactosyldipeptides were examined as galactosyl acceptors. They both contain an L-serine residue beta-linked to the anomeric carbon of galactose. In the first series, serine is in the N-terminal position of the dipeptide; in the second series, serine is in the C-terminal position. The second amino acid is L-alanine or glycine. Some of our substrates gave a high yield of beta-(1-->3)-digalactosyldipeptide derivatives and all gave very little of the beta-(1-->6) regioisomer. The conditions and the limitations of the transgalactosylation reaction are discussed

Evaluation of Biological Treatments for the Adsorption of Phenol from Polluted Waters

In this study, we describe the efficiency of three biological techniques (using Pseudomonas aeruginosa ) for the removal of phenol from polluted water. We explore the possibilities of elimination with free bacteria present in solution, fixed bacteria on granular activated carbon (GAC) and immobilized bacteria in calcium alginate beads. Our study results show that for all the three methods the removal of phenol from solution (300 mg l −1 ) is complete. The kinetic constants for phenol removal are equivalent for two methods, namely, bacteria fixed on the GAC and those immobilized in calcium alginate beads (≈0.2 h −1 ), while for the free bacteria in solution, it is about half of this value. We also report how the biomass production in solution depends on the method applied. The concentration seems to act as a regulator for the amount of bacteria released in solution
