The known human tumor viruses include the DNA viruses Epstein-Barr virus, Kaposi sarcoma herpesvirus, Merkel cell polyomavirus, human papillomavirus, and hepatitis B virus. RNA tumor viruses include Human T-cell lymphotrophic virus type-1 and hepatitis C virus. The serological identification of antigens/antibodies in plasma serum is a rapidly progressing field with utility for both scientists and clinicians. Serology is useful for conducting seroepidemiology studies and to inform on the pathogenesis and host immune response to a particular viral agent. Clinically, serology is useful for diagnosing current or past infection and for aiding in clinical management decisions. Serology is useful for screening blood donations for infectious agents and for monitoring the outcome of vaccination against these viruses. Serodiagnosis of human tumor viruses has improved in recent years with increased specificity and sensitivity of the assays, as well as reductions in cost and the ability to assess multiple antibody/antigens in single assays. Serodiagnosis of tumor viruses plays an important role in our understanding of the prevalence and transmission of these viruses and ultimately in the ability to develop treatments/preventions for these globally important diseases.

OBJECTIVE To analyze HIV/AIDS positive individual’s perception and attitudes regarding dental services. METHODS One hundred and thirty-four subjects (30.0% of women and 70.0% of men) from Nuevo León, Mexico, took part in the study (2014). They filled out structured, analytical, self-administered, anonymous questionnaires. Besides the sociodemographic variables, the perception regarding public and private dental services and related professionals was evaluated, as well as the perceived stigma associated with HIV/AIDS, through a Likert-type scale. The statistical evaluation included a factorial and a non-hierarchical cluster analysis. RESULTS Social inequalities were found regarding the search for public and private dental professionals and services. Most subjects reported omitting their HIV serodiagnosis and agreed that dentists must be trained and qualified to treat patients with HIV/AIDS. The factorial analysis revealed two elements: experiences of stigma and discrimination in dental appointments and feelings of concern regarding the attitudes of professionals or their teams concerning patients’ HIV serodiagnosis. The cluster analysis identified three groups: users who have not experienced stigma or discrimination (85.0%); the ones who have not had those experiences, but feel somewhat concerned (12.7%); and the ones who underwent stigma and discrimination and feel concerned (2.3%). CONCLUSIONS We observed a low percentage of stigma and discrimination in dental appointments; however, most HIV/AIDS patients do not reveal their serodiagnosis to dentists out of fear of being rejected. Such fact implies a workplace hazard to dental professionals, but especially to the very own health of HIV/AIDS patients, as dentists will not be able to provide them a proper clinical and pharmaceutical treatment.

Glanders is a contagious disease caused by the Gram-negative bacillus Burkholderia mallei. The number of equine glanders outbreaks has increased steadily during the last decade. The disease must be reported to the Office International des Epizooties, Paris, France. Glanders serodiagnosis is hampered by the considerable number of false positives and negatives of the internationally prescribed tests. The major problem leading to the low sensitivity and specificity of the complement fixation test (CFT) and enzyme-linked immunosorbent assay (ELISA) has been linked to the test antigens currently used, i.e., crude preparations of whole cells. False-positive results obtained from other diagnostic tests utilizing crude antigens lead to financial losses to animal owners, and false-negative results can turn a risk into a possible threat. In this study, we report on the identification of diagnostic targets using bioinformatics tools for serodiagnosis of glanders. The identified gene sequences were cloned and expressed as recombinant proteins. The purified recombinant proteins of B. mallei were used in an indirect ELISA format for serodiagnosis of glanders. Two recombinant proteins, 0375H and 0375TH, exhibited 100% sensitivity and specificity for glanders diagnosis. The proteins also did not cross-react with sera from patients with the closely related disease melioidosis. The results of this investigation highlight the potential of recombinant 0375H and 0375TH proteins in specific and sensitive diagnosis of glanders.

Serodiagnosis of human toxocariasis is difficult in tropical areas where other helminthiasis are endemic. Many studies have shown that glycans from helminths may be the responsible for cross-reactions in the immunoassays. In this study, we have evaluated the deglycosylation of the Toxocara canis excretory-secretory (TES) antigens for the detection of IgG antibodies using a panel of 228 serum samples (58 patients with toxocariasis, 75 patients with other helminth infections and 95 healthy individuals) by ELISA and Western blot assays. Our results showed that the deglycosylation of TES antigens resulted in a single fraction of 26 kDa (dTES) and was able to detect IgG antibodies with a sensitivity and specificity of 100% in both above-mentioned assays. The rate of cross-reactions, observed in ELISA with TES (13·3%), was significantly reduced (5·3%) when the dTES antigens were used. Likewise, the cross-reactivity observed with the fractions of 32, 55 and 70 kDa of the TES antigens was totally eliminated when the dTES were used in the Western blot. All these results showed that the deglycosylation of the TES antigens really improves the specificity of the serodiagnosis of human toxocariasis in endemic areas for helminth infections.

An indirect enzyme-linked immunosorbent assay (ELISA) was developed and evaluated for its diagnostic ability to detect human IgG antibodies against Fasciola hepatica saposin-like protein-2. The assay was compared with an indirect ELISA with excretory-secretory products (FhES) from adult F. hepatica. In an analysis of the sera of 37 patients infected with F. hepatica, 40 patients with other parasitic infections, and 50 healthy controls, the sensitivity of both ELISA assays was 100%. However, the FhSAP2-based ELISA was more specific (95.6%) than the FhES-ELISA (91.9%). These results demonstrated that FhSAP2 can be used in the serodiagnosis of chronic human fascioliasis with additional advantage that is relative cheap and easy to produce. Studies are in progress to evaluate this FhSAP2-ELISA assay in a large-scale prevalence surveys in endemic areas. PMID:21683266
Full Text Available ESAT-6 is one of the most studied antigens in vaccine, diagnosis, and pathogenic mechanism of tuberculosis. In the present study, a meta-analysis was performed regarding the use of ESAT-6 based antibody detection test for diagnosing nonhuman primate (NHP tuberculosis. Studies in English and Chinese were searched and selected strictly. Quality of included studies was assessed using the standardized QUADAS-2 tool. Heterogeneity was explored through meta-regression. Finally, eight studies were included with high degree of homogeneity. Quality of included studies was general satisfied except the bias of “patient selection” for the majority of serum samples were from experimental infections. Estimates of sensitivity ranged from 69% to 82%, while specificity ranged from 96% to 99%. Area under ROC curves and Q were 0.9503 and 0.8909 respectively, indicating a high diagnostic accuracy. Current evidence suggests that ESAT-6 based serodiagnosis has the potential to become useful diagnostic tools for NHP tuberculosis.

Counter-current immuno-electrophoresis was evaluated as a diagnostic test for the serodiagnosis of typhoid fever with somatic (O), flagellar (H) and capsular polysaccharide (Vi) antigens of Salmonella typhi on the sera of patients who were blood culture positive (confirmed typhoid cases) or had high Widal agglutination titres, > or = 320, (presumptive typhoid cases). Of the 37 sera from confirmed cases, 30% showed positivity with O antigen, 24% with H antigens and 51% with Vi antigen. In patients with a presumptive diagnosis, 45% were positive for O antibody, 27% for flagellar antibody and 52% for Vi antibody. When all three antigens were combined the reactivity to any of the antigens was found to be 59% in confirmed typhoid cases, 79% in presumptive typhoid cases and 93% in patients who were simultaneously positive by blood culture and Widal agglutination. However, none of the sera from 45 controls gave a positive precipitation reaction with any of the antigens. It is concluded that counter-current immuno-electrophoresis is a rapid test with low sensitivity and high specificity with Vi antigen, a panel of antigens being most effective, and is, therefore, recommended for rapid diagnosis of typhoid fever.

Background: Parasite proteases have important roles in cleavage of host proteins during the invasion of host tissues and participate in the parasite’s evasion from the host’s immune response. The aim of the present study was to estimate a metalloproteinase properties of Taenia solium metacestode (TsMP) during host-parasite interactions, and evaluate its potential as a serodiagnostic antigen for cysticercosis. Methods: The cDNA coding for the mature catalytic domain of TsMP was cloned into pGEX-6P-1 expression vector. A recombinant glutathione S-transferase and TsMP fusion protein was induced. After refolding and purification, enzymatic properties of the recombinant metalloproteinase were observed. Immunoblot assay was processed to evaluate its potential as a serodiagnostic antigen for cysticercosis. Results: The recombinant TsMP protein showed proteolytic activity, which preferred host extracellular matrix proteins such as collagen and fibronectin as degradable substrates. In immunoblot assay, 87.5% of sera from patients with cysticercosis showed strong reactivity. In sera from patients with other parasitic infections and from normal controls, it showed high specificity. Conclusions: TsMP might be involved in the processing of numerous host proteins and play an important role in the parasite life cycle. A single recombinant TsMP antigen could have a potential value for serodiagnosis of cysticercosis. PMID:27095967

Carbohydrates of pathogen antigens have been disrupted by periodate oxidation, in order to reduce nonspecific bindings and improve serodiagnosis of parasite infections. In the present study, the enzyme-linked immunosorbent assay (ELISA) was carried out with filariform larvae antigen treated, or not treated, with sodium metaperiodate. Groups of sera from patients with Strongyloides stercoralis infection, with other intestinal parasites and a normal control, were used. The oxidation of Strongyloides stercoralis glycosylated epitopes reduced the seroreactivity of sera from patients with S. stercoralis infection as demonstrated by ELISA, with a decrease in sera optical densities. The number of cross-reactions of IgG and IgE-ELISAs increased by 12% and 16%, respectively, after antigen treatment with metaperiodate. This was more often observed in patients infected with Schistosoma mansoni and hookworm. Moreover, the IgG depletion from sera tested by IgE-ELISA led to the detection of previous false-negative samples from S. stercoralis-infected patients.

An anti-pertussis toxin (PT) IgG enzyme-linked immunosorbent assay (ELISA) was analytically validated for the diagnosis of pertussis at a cutoff of 94 ELISA units (EU)/ml. Little was known about the performance of this ELISA in the diagnosis of adults recently vaccinated with tetanus-diphtheria-acellular pertussis (Tdap) vaccine, which contains PT. The goal of this study was to determine when the assay can be used following Tdap vaccination. A cohort of 102 asymptomatic health care personnel (HCP) vaccinated with Tdap (Adacel; Sanofi Pasteur) were aged 19 to 79 years (median, 47 years) at vaccination. For each HCP, specimens were available for evaluation at 2 to 10 time points (prevaccination to 24 months postvaccination), and geometric mean concentrations (GMC) for the cohort were calculated at each time point. Among 97 HCP who responded to vaccination, a mixed-model analysis with prediction and tolerance intervals was performed to estimate the time at which serodiagnosis can be used following vaccination. The GMCs were 8, 21, and 9 EU/ml at prevaccination and 4 and 12 months postvaccination, respectively. Eight (8%) of the 102 HCP reached antibody titers of ≥94 EU/ml during their peak response, but none had these titers by 6 months postvaccination. The calculated prediction and tolerance intervals were <94 EU/ml by 45 and 75 days postvaccination, respectively. Tdap vaccination 6 months prior to testing did not confound result interpretation. This seroassay remains a valuable diagnostic tool for adult pertussis.
Full Text Available Mycobacterial infections—tuberculosis (TB, bovine tuberculosis (bTB, and Johne’s disease (JD—are major infectious diseases of both human and animals. Methods presently in use for diagnosis of mycobacterial infections include bacterial culture, nucleic acid amplification, tuberculin skin test, interferon-γ assay, and serology. Serological tests have several advantages over other methods, including short turn-around time, relatively simple procedures, and low cost. However, current serodiagnostic methods for TB, bTB and JD exhibit low sensitivity and/or specificity. Recent studies that have aimed to develop improved serodiagnostic tests have mostly focused on identifying useful species-specific protein antigens. A review of recent attempts to improve diagnostic test performance indicates that the use of multiple antigens can improve the accuracy of serodiagnosis of these mycobacterial diseases. Mycobacteria also produce a variety of species-specific nonprotein molecules; however, only a few such molecules (e.g., cord factor and lipoarabinomannan have so far been evaluated for their effectiveness as diagnostic antigens. For TB and bTB, there has been recent progress in developing laboratory-free diagnostic methods. New technologies such as microfluidics and “Lab-on-Chip” are examples of promising new technologies that can underpin development of laboratory-free diagnostic devices for these mycobacterial infections.
Rapid and accurate diagnosis of infectious diseases, including mycobacterial disease such as tuberculosis (TB) and diseases due to nontuberculous mycobacteria (NTM), is a very important element of global health. The gold standard in diagnosis of mycobacterial diseases remains clinical examination, combined with direct microscopic examination of sputum and culture of bacteria. Culture of slowly growing mycobacteria, including Mycobacterium tuberculosis and NTM (such as M. avium complex: MAC), can take up to 4 to 6 weeks, and in 10-20% of cases the bacillus is not successfully cultivated. Diagnosis of MAC pulmonary disease (MAC-PD) is complicated and time-consuming (usually at least 1 month). I have characterized the nature of MAC antigens and immune responses from the aspect of basic mycobacteriology, and then translated to clinical science. My multicenter study in Japan has demonstrated the usefulness of a serodiagnostic test to determine serum IgA antibodies against mycobacterial glycopeptidolipid (GPL) core antigen for diagnosing MAC-PD within a few hours. To validate in a larger number of patients, at diverse geographic locations, and among other races, the test was also assessed the usefulness internationally in the United States and Taiwan. In this review, I discuss development of serodiagnosis of MAC-PD by translational research and international collaboration study.

Full Text Available To improve the serodiagnosis of human toxocariasis, a sensitive and specific enzyme-linked immunoelectrotransfer blot (EITB-IgG test was developed and evaluated using Toxocara canislarvae excretory-secretory antigens for detecting anti-Toxocara IgG antibodies. The EITB-IgG profile of toxocariasis was characterized by comparing 27 sera from patients with toxocariasis, 110 sera from healthy subjects and 186 sera from patients with other helminth diseases (ascariasis, ancylostomiasis, trichuriasis, enterobiasis, strongyloidiasis, hymenolepiasis, diphyllobothriasis, taeniasis, cysticercosis, hydatidosis and fascioliasis. Antigenic bands of 24, 28, 30, 35, 56, 117, 136 and 152 kDa were predominantly recognized in sera from all patients with toxocariasis. However, only bands of 24-35 kDa were highly specific for Toxocara infection (98.3%, whereas other antigenic bands observed displayed cross-reactivity. Additionally, when the results of the EITB-IgG test were compared to those of the ELISA-IgG test, a 100% concordance was observed for positive results in human toxocariasis cases. The concordance for negative results between the two tests for healthy subjects and patients with other helminth diseases were 96.3% and 53.7%, respectively, showing that the EITB-IgG test has a higher specificity than ELISA. In conclusion, the EITB-IgG test is a very useful tool to confirm the serological diagnosis of human toxocariasis.

Toxocariasis is a worldwide zoonosis caused by larvae of ascarid nematodes of dogs or cats, Toxocara canis or T. cati. Diagnosis of human toxocariasis currently relies on serology that uses T. canis excretory-secretory antigen to detect specific IgG antibodies by ELISA. We investigated the serodiagnostic efficacy of ELISA using crude antigen of T. canis larvae (TCLA). Serum specimens of 64 clinically confirmed toxocariasis, 115 healthy controls, and 119 other tissue-invading helminthiases were screened by ELISA using TCLA. The ELISA using TCLA showed 92.2% (59/64 patient samples) sensitivity and 86.6% (103/119) specificity. Its positive diagnostic predictivity was 78.7% and negative predictivity was 97.8%. No serum of healthy controls reacted but that of anisakiasis (45.5%), gnathostomiasis (19.2%), clonorchiasis (15.8%), sparganosis (11.1%), and cysticercosis (6.3%) cross-reacted. Immunoblot analysis on TCLA recognized antigenic proteins of 28- and 30-kDa bands in their dominant protein quantity and strong blotting reactivity. The present results indicate that the ELISA using our TCLA antigen is acceptable by the sensitivity and specificity for serodiagnosis of human toxocariasis. ELISA with TCLA is recommended to make differential diagnosis for patients with any sign of organ infiltration and eosinophilia.
Full Text Available BACKGROUND: Human fasciolosis is a re-emerging disease worldwide and is caused by species of the genus Fasciola (F. hepatica and F. gigantica. Human fasciolosis can be diagnosed by classical coprological techniques, such as the Kato-Katz test, to reveal parasite eggs in faeces. However, although 100% specific, these methods are generally not adequate for detection of acute infections, ectopic infections, or infections with low number of parasites. In such cases immunological methods may be a good alternative and are recommended for use in major hospitals where trained personnel are available, although they are not usually implemented for individual testing. METHODOLOGY/PRINCIPAL FINDINGS: We have developed a new lateral flow test (SeroFluke for the serodiagnosis of human fasciolosis. The new test was constructed with a recombinant cathepsin L1 from F. hepatica, and uses protein A and mAb MM3 as detector reagents in the test and control lines, respectively. In comparison with an ELISA test (MM3-SERO the SeroFluke test showed maximal specificity and sensitivity and can be used with serum or whole blood samples. CONCLUSIONS/SIGNIFICANCE: The new test can be used in major hospitals in hypoendemic countries as well as in endemic/hyperendemic regions where point-of-care testing is required.

Full Text Available Abstract Background The in vivo diagnosis of glanders relies on the highly sensitive complement fixation test (CFT. Frequently observed false positive results are troublesome for veterinary authorities and cause financial losses to animal owners. Consequently, there is an urgent need to develop a test with high specificity. Hence, a Western blot assay making use of a partly purified lipopolysaccaride (LPS containing antigen of three Burkholderia mallei strains was developed. The test was validated investigating a comprehensive set of positive and negative sera obtained from horses and mules from endemic and non endemic areas. Results The developed Western blot assay showed a markedly higher diagnostic specificity when compared to the prescribed CFT and therefore can be used as a confirmatory test. However, the CFT remains the test of choice for routine testing of glanders due to its high sensitivity, its feasibility using standard laboratory equipment and its worldwide distribution in diagnostic laboratories. Conclusions The CFT should be amended by the newly validated Western blot to increase the positive likelihood ratio of glanders serodiagnosis in non endemic areas or areas with low glanders prevalence. Its use for international trade of horses and mules should be implemented by the OIE.

Full Text Available A kit based on an enzyme immunoassay, EIE-Recombinant-Chagas-Biomanguinhos, developed by the Oswaldo Cruz Foundation, was evaluated for the serodiagnosis of chronic Chagas disease. Evaluation was performed with 368 serum samples collected from individuals living in an endemic area for Chagas disease: 131 patients in the chronic phase with confirmed clinical, epidemiological, and serological diagnosis (indirect immunofluorescence, indirect hemagglutination or enzyme-linked immunosorbent assay and 237 nonchagasic seronegative individuals were considered negative control. The EIE-Recombinant-Chagas-Biomanguinhos kit showed high sensitivity, 100% (CI 95%: 96.4-100% and high specificity, 100% (CI 95%: 98-100%. The data obtained were in full agreement with clinical and conventional serology data. In addition, no cross-reaction was observed with sera from patients with cutaneous (n=14 and visceral (n=3 leishmaniasis. However, when these sera were tested by conventional serological assays for Chagas disease, cross-reactions were detected in 14.3% and 33.3% of the patients with cutaneous and visceral leishmaniasis, respectively. No cross-reactions were observed when sera from nonchagasic seronegative patients bearing other infectious disease (syphilis, n=8; HTLV, n=8; HCV, n=7 and HBV, n=12 were tested. In addition, sera of patients with inconclusive results for Chagas disease by conventional serology showed results in agreement with clinical evaluation, when tested by the kit. These results are relevant and indicate that the refered kit provides a safe immunodiagnosis of Chagas disease and could be used in blood bank screening.
Full Text Available Individual rapid tests for serodiagnosis (RDT of human African trypanosomiasis (HAT are particularly suited for passive screening and surveillance. However, so far, no large scale evaluation of RDTs has been performed for diagnosis of Trypanosoma brucei gambiense HAT in West Africa. The objective of this study was to assess the diagnostic accuracy of 2 commercial HAT-RDTs on stored plasma samples from West Africa.SD Bioline HAT and HAT Sero-K-Set were performed on 722 plasma samples originating from Guinea and Côte d'Ivoire, including 231 parasitologically confirmed HAT patients, 257 healthy controls, and 234 unconfirmed individuals whose blood tested antibody positive in the card agglutination test but negative by parasitological tests. Immune trypanolysis was performed as a reference test for trypanosome specific antibody presence. Sensitivities in HAT patients were respectively 99.6% for SD Bioline HAT, and 99.1% for HAT Sero-K-Set, specificities in healthy controls were respectively 87.9% and 88.3%. Considering combined positivity in both RDTs, increased the specificity significantly (p ≤ 0.0003 to 93.4%, while 98.7% sensitivity was maintained. Specificities in controls were 98.7-99.6% for the combination of one or two RDTs with trypanolysis, maintaining a sensitivity of at least 98.1%.The observed specificity of the single RDTs was relatively low. Serial application of SD Bioline HAT and HAT Sero-K-Set might offer superior specificity compared to a single RDT, maintaining high sensitivity. The combination of one or two RDTs with trypanolysis seems promising for HAT surveillance.

Access to appropriate diagnostic tools is an essential component in the evaluation and improvement of global health. Additionally, timely detection of infectious agents is critical in early diagnosis and treatment of infectious diseases. Conventional pathogen detection methods such as culturing, enzyme linked immunosorbent assay (ELISA) or polymerase chain reaction (PCR) require long assay times, and complex and expensive instruments making them not adaptable to point-of-care (PoC) needs at resource-constrained places and primary care settings. Therefore, there is an unmet need to develop portable, simple, rapid, and accurate methods for PoC detection of infections. Here, we present the development and validation of a portable, robust and inexpensive electrochemical magnetic microbeads-based biosensor (EMBIA) platform for PoC serodiagnosis of infectious diseases caused by different types of microorganisms (parasitic protozoa, bacteria and viruses). We demonstrate the potential use of the EMBIA platform for in situ diagnosis of human (Chagas disease and human brucellosis) and animal (bovine brucellosis and foot-and-mouth disease) infections clearly differentiating infected from non-infected individuals or animals. For Chagas disease, a more extensive validation of the test was performed showing that the EMBIA platform displayed an excellent diagnostic performance almost indistinguishable, in terms of specificity and sensitivity, from a fluorescent immunomagnetic assay and the conventional ELISA using the same combination of antigens. This platform technology could potentially be applicable to diagnose other infectious and non-infectious diseases as well as detection and/or quantification of biomarkers at the POC and primary care settings.

Serodiagnosis of human toxocariasis is based on the detection of specific IgG antibodies by the enzyme-linked immunosorbent assay (ELISA) using Toxocara larvae excretory-secretory (TES) antigens, but its production is a laborious and time-consuming process being also limited by the availability of adult females of T. canis as source for ova to obtain larvae. Chemical synthesis of the di-O-methylated (DiM) glycan structure found in the TES antigens has provided material for studying the antibody reactivity in a range of mammalian hosts, showing reactivity with human IgM and IgG. In this study, we have evaluated the performance of the DiM glycan against a panel of sera including patients with toxocariasis (n = 60), patients with other helminth infections (n = 75) and healthy individuals (n = 94), showing that DiM is able to detect IgG antibodies with a sensitivity and specificity of 91·7% and 94·7%, respectively, with a very good agreement with the TES antigens (kappa = 0·825). However, cross-reactivity was observed in some sera from patients with ascariasis, hymenolepiasis and fascioliasis.

Toxocariasis is a cosmopolitan zoonotic disease caused by the infective larvae of Toxocara canis and T. cati. Diagnosis in humans is usually based on clinical symptoms and serology. Immunoglobulin G (IgG)-enzyme-linked immunosorbent assay kits using T. canis excretory-secretory (TES) larval antigens are commonly used for serodiagnosis. Differences in the antigens of the two Toxocara species may influence the diagnostic sensitivity of the test. In this study, T. cati recombinant TES-120 (rTES-120) was cloned, expressed, and compared with its T. canis homolog in an IgG4-western blot. The diagnostic sensitivity and specificity of T. cati rTES-120 were 70% (33/47) and 100% (39/39), respectively. T. canis rTES-120 showed 57.4% sensitivity and 94.4% specificity. When the results of assays using rTES-120 of both species were considered, the diagnostic sensitivity was 76%. This study shows that using antigens from both Toxocara species may improve the serodiagnosis of toxocariasis.

Trypanosoma evansi, the causative agent of surra, infects different domestic and wild animals and has a wide geographical distribution. It is mechanically transmitted mainly by haematophagous flies. Parasitological techniques are commonly used for the diagnosis of surra but have limited sensitivity. Therefore, serodiagnosis based on the detection of T. evansi specific antibodies is recommended by the World Organisation for Animal Health (OIE). Recently, we developed a new antibody detection test for the serodiagnosis of T. evansi infection, the Surra Sero K-SeT. Surra Sero K-SeT is an immunochromatographic test (ICT) that makes use of recombinant variant surface glycoprotein rVSG RoTat 1.2, produced in the yeast Pichia pastoris. In this study, we compared the diagnostic accuracy of the Surra Sero K-SeT and the Card Agglutination Test for T. evansi Trypanosomososis (CATT/T. evansi) with immune trypanolysis (TL) as reference test on a total of 806 sera from camels, water buffaloes, horses, bovines, sheep, dogs and alpacas. Test agreement was highest between Surra Sero K-SeT and TL (κ=0.91, 95% CI 0.841-0.979) and somewhat lower between CATT/T. evansi and TL (κ=0.85, 95% CI 0.785-0.922) and Surra Sero K-SeT and CATT/T. evansi (κ=0.81, 95% CI 0.742-0.878). The Surra Sero K-SeT displayed a somewhat lower overall specificity than CATT/T. evansi (94.8% versus 98.3%, χ(2)=13.37, p<0.001) but a considerably higher sensitivity (98.1% versus 84.4%, χ(2)=33.39, p<0.001). We conclude that the Surra Sero K-SeT may become an alternative for the CATT/T. evansi for sensitive detection of antibodies against T. evansi in domestic animals.

Leptospirosis is a zoonotic disease that occurs worldwide, particularly in tropical countries. In livestock the agent is responsible for reproductive problems such as infertility and abortion. Serogroup Sejroe, particularly serovar Hardjo, prevails in cattle in several regions. The microscopic agglutination test (MAT) is the current method for diagnosing leptospirosis. It has been proposed that the inclusion of local strains could detect a larger set of seroreactive animals. In that context, the aim of the present study was to evaluate if the usage of local strains as antigens increases the sensitivity of the serodiagnosis of bovine leptospirosis. Blood and urine samples were collected from 314 bovines from several herds randomly selected in a slaughterhouse in Rio de Janeiro, Brazil. Serological diagnosis was made with MAT using a 21 reference-strains panel (MAT21). Additionally, 12 local strains (MAT33) were included as antigens. PCR was performed with the urine samples and it was positive on 71 out of 222 samples (31.9%). MAT21 identified as seroreactive 173 (55.1%) out of the 314 animals studied, with Sejroe the most common (38.1%). In MAT33, 204 (65.0%) animals were seroreactive with a significant increase on seroreactivity (9.9%). In conclusion, MAT presented with a significant increase of sensitivity when local strains were used as antigens. Among the local strains, 2013_U152 (KP263062) (serogroup Shermani) and 2013_U280 (KP263069) (serogroup Grippotyphosa) showed to be more antigenic.

Currently, infectious syphilis has been resurgent in China and has become a significant public health problem. The rapid expansion of syphilis screening programs is urgently required. In the present study, the performance of the Determine Syphilis TP assay (Determine TP assay) for the detection of antibodies against Treponema pallidum (T. pallidum) for syphilis serodiagnosis was evaluated. In total, 300 serum samples were tested for the presence of treponemal-specific antibodies using the Treponema pallidum particle agglutination (TPPA) assay, the Determine TP assay, and the InTec immunochromatography assay (InTec assay). The Determine TP assay detected 99, 11, and 5 positive results, whereas the InTec assay detected 97, 3, and 3 positive samples from group I (100 TPPA-positive sera), group II (13 TPPA 1:80 +/- sera), and group III (187 TPPA-negative sera), respectively. The sensitivity, specificity, and the rate concordant with TPPA for the Determine TP assay were 97.35, 98.91, and 97.33%, respectively. In comparison to the TPPA, the Determine TP assay is simple to perform and time-saving, making it a favorable alternative for the detection of T. pallidum-specific antibodies where other T. pallidum-specific confirmatory tests are not available. In addition, this rapid treponemal test promotes prompt treatment for syphilis by providing early laboratory diagnosis.
Full Text Available Objective. To express truncated TssB protein of Burkholderia mallei and to evaluate its diagnostic efficacy for serological detection of glanders among equines. Materials and Methods. In an attempt to develop recombinant protein based enzyme-linked immunosorbent assay (ELISA, N-terminal 200 amino acid sequences of B. mallei TssB protein—a type 6 secretory effector protein—were expressed in prokaryotic expression system. Diagnostic potential of recombinant TssB protein was evaluated in indirect ELISA using a panel of glanders positive (n=49, negative (n=30, and field serum samples (n=1811. Cross-reactivity of the assay was assessed with equine disease control serum and human melioidosis positive serum. Results. In comparison to CFT, diagnostic sensitivity and specificity of ELISA were 99.7% and 100%, respectively. Conclusions. The indirect ELISA method using the truncated TssB offered safer and more rapid and efficient means of serodiagnosis of glanders in equines. These data highlight the use of TssB as potential diagnostic antigen for serological diagnosis of glanders.

Neosporosis is an infectious disease caused by Neospora caninum, and it primarily affects cattle and dogs. An infection by N. caninum causes fetal abortion and neonatal mortality. Previous proteomics and immunoscreening analyses revealed that N. caninum dense granule antigen 2 (NcGRA2) has potential for serodiagnosis of N. caninum. Consequently, we expressed the truncated NcGRA2 (NcGRA2t), which lacks a signal peptide. We compared the serodiagnostic performances of recombinant NcGRA2t with that of truncated surface antigen 1 of N. caninum (NcSAG1t). Specificity testing using sera from mice infected with Toxoplasma gondii indicated that the NcGRA2t recombinant protein does not cross-react with T. gondii. In addition, we detected anti-NcGRA2t antibody at the acute stage in experimentally infected dogs, while detecting anti-NcSAG1t antibody during both the acute and chronic stages. Our results suggest that the levels of anti-NcGRA2 antibody reflect parasite activation in dogs. In conclusion, antibodies against NcGRA2t and NcSAG1t are suitable indicators to distinguish the acute and chronic stages of N. caninum infection.

Serological methods used to diagnose visceral leishmaniasis (VL) are considered minimally invasive, but they present problems related with their sensitivity and/or specificity. In this study, a subtractive selection using the phage display technology against antibodies from healthy subjects living in endemic and non-endemic areas of disease, as well as from Chagas disease patients and those developing active VL, was developed. The aim of this study was to select bacteriophage-fused epitopes to be used in the serodiagnosis of human VL. Eight phage clones were selected after the bio-panning rounds, and their reactivity was evaluated in a phage-ELISA assay against a human serological panel. A wild-type clone and the recombinant K39-based immunochromatographic test were used as controls. In the results, it was shown that all clones showed an excellent performance to serologically identify VL patients, demonstrating the feasibility of the isolated phages for developing a specific and sensitive serodiagnosis of human VL.

The correct and early identification of humans and dogs infected with Leishmania are key steps in the control of leishmaniasis. Additionally, a method with high sensitivity and specificity at low cost that allows the screening of a large number of samples would be extremely valuable. In this study, we analyzed the potential of mitogen-activated protein kinase 3 (MAPK3) and mitogen-activated protein kinase 4 (MAPK4) proteins from Leishmania braziliensis to serve as antigen candidates for the serodiagnosis of human visceral and tegumentary leishmaniasis, as well as canine visceral disease. Moreover, we mapped linear B-cell epitopes in these proteins and selected those epitopes with sequences that were divergent in the corresponding orthologs in Homo sapiens, in Canis familiaris, and in Trypanosoma cruzi. We compared the performance of these peptides with the recombinant protein using ELISA. Both MAPK3 and MAPK4 recombinant proteins showed better specificity in the immunodiagnosis of human and canine leishmaniasis than soluble parasite antigens and the EIE-leishmaniose-visceral-canina-bio-manguinhos (EIE-LVC) kit. Furthermore, the performance of this serodiagnosis assay was improved using synthetic peptides corresponding to B-cell epitopes derived from both proteins.
Full Text Available Two recombinant Fasciola hepatica antigens, saposin-like protein-2 (recSAP2 and cathepsin L-1 (recCL1, were assessed individually and in combination in enzyme-linked immunosorbent assays (ELISA for the specific serodiagnosis of human fasciolosis in areas of low endemicity as encountered in Central Europe. Antibody detection was conducted using ProteinA/ProteinG (PAG conjugated to alkaline phosphatase. Test characteristics as well as agreement with results from an ELISA using excretory-secretory products (FhES from adult stage liver flukes was assessed by receiver operator characteristic (ROC analysis, specificity, sensitivity, Youdens J and overall accuracy. Cross-reactivity was assessed using three different groups of serum samples from healthy individuals (n=20, patients with other parasitic infections (n=87 and patients with malignancies (n=121. The best combined diagnostic results for recombinant antigens were obtained using the recSAP2-ELISA (87% sensitivity, 99% specificity and 97% overall accuracy employing the threshold (cut-off to discriminate between positive and negative reactions that maximized Youdens J. The findings showed that recSAP2-ELISA can be used for the routine serodiagnosis of chronic fasciolosis in clinical laboratories; the use of the PAG-conjugate offers the opportunity to employ, for example, rabbit hyperimmune serum for the standardization of positive controls.

This article reviews a peer group Acquired Immunodeficiency Syndrome (AIDS) educational program at a university in Australia. Studies in the US have shown that most adolescents, although sexually active, do not believe they are likely to become infected with the Human Immunodeficiency Virus, and therefore do not attempt to modify their sexual behavior. A 1st step in educating students is to introduce them to condoms and impress upon them the fact that condoms should be used at the beginning of all sexual relationships, whether homosexual or heterosexual. In this program 3rd year medical students were targeted, as they are effective communicators and disseminators of information to the rest of the student body. After class members blow up condoms, giving them a chance to handle various brands and observe the varying degrees of strength, statistical evidence about the contraceptive failure rate of condoms (0.6-14.7 per 100 women-years) is discussed. Spermicides, such as nonoxynol-9 used in conjunction with condoms, are also discussed, as are condoms for women, packaging and marketing of condoms, including those made from latex and from the caecum of sheep, the latter condoms being of questionable effectiveness in preventing transmission of the virus. The care of terminal AIDS cases and current global and national statistics on AIDS are presented. The program also includes cash prizes for the best student essays on condom use, the distribution of condoms, condom key rings and T-shirts, and a student-run safe sex stand during orientation week. All of these activities are intended to involve students and attract the interest of the undergraduate community. Questionnaires administered to students at the end of the course revealed that the lectures were received favorably. Questionnaires administered to new medical and English students attending orientation week revealed that 72% of students thought the stand was a good idea and 81% and 83%, respectively found it

This study presents an evaluation of the MIC1 (microneme protein 1)-MAG1 (matrix antigen 1) Toxoplasma gondii recombinant chimeric antigen for the serodiagnosis of human toxoplasmosis for the first time. The recombinant MIC1-MAG1 antigen was obtained as a fusion protein containing His tags at the N- and C-terminal ends using an Escherichia coli expression system. After purification by metal affinity chromatography, the chimeric protein was tested for usefulness in an enzyme-linked immunosorbent assay (ELISA) for the detection of anti-T. gondii immunoglobulin G (IgG). One hundred ten sera from patients at different stages of infection and 40 sera from seronegative patients were examined. The results obtained for the MIC1-MAG1 chimeric antigen were compared with those of IgG ELISAs using a Toxoplasma lysate antigen (TLA), a combination of recombinant antigens (rMIC1ex2-rMAG1) and single recombinant proteins (rMIC1ex2 and rMAG1). The sensitivity of the IgG ELISA calculated from all of the positive serum samples was similar for the MIC1-MAG1 chimeric antigen (90.8%) and the TLA (91.8%), whereas the sensitivities of the other antigenic samples used were definitely lower, at 69.1% for the mixture of antigens, 75.5% for the rMIC1ex2, and 60% for rMAG1. This study demonstrates that the MIC1-MAG1 recombinant chimeric antigen can be used instead of the TLA in the serodiagnosis of human toxoplasmosis.

Syphilis is a multistage disease caused by the invasive spirochete Treponema pallidum subsp. pallidum, and accurate diagnosis is important for the prevention and treatment of syphilis. Here, to identify appropriate diagnostic antigens for serodiagnosis of syphilis, 6 recombinant proteins were expressed in Escherichia coli and purified, including flagellins (FlaB1 [Tp0868], FlaB2 [Tp0792], and FlaB3 [Tp0870]), Tp0463, Tp0751, and Tp1038. The sensitivities were determined by screening sera from individuals with primary (n=82), secondary (n=115), latent (n=105), and congenital (n=65) syphilis. The specificities were determined by screening sera from uninfected controls (n=30) and potentially cross-reactive infections including Lyme disease (n=30), leptospirosis (n=5), and hepatitis B (n=30). Our data showed that FlaB1, FlaB2, FlaB3, Tp0463, and Tp1038 exhibited higher overall sensitivities and specificities for detecting IgG antibody, with 95.4% and 98.9%, 92.6% and 95.8%, 95.1% and 95.8%, 92.6% and 97.9%, and 95.9% and 98.9%, respectively. In contrast, Tp0751 demonstrated only an overall sensitivity of 39.2%. For comparison, the sensitivity and specificity of Architect Syphilis TP were determined to be 98.1% and 93.7%, respectively. In addition, FlaB1, FlaB2, FlaB3, and Tp0463 demonstrated excellent performance for detecting IgM antibody in primary and congenital syphilis, with sensitivities of 76.8% and 83.1%, 72.0% and 87.7%, 74.4% and 89.2%, and 64.6% and 75.3%, respectively. These results indicate that FlaB1, FlaB2, FlaB3, and Tp0463 could be as novel diagnostic candidates for serodiagnosis of syphilis.

The applicability of the recombinant LipL32 for serodiagnosis of leptospiral infection in field rodents was assessed in this study. An immunodominant region of LipL32 was determined by monoclonal antibodies, and then, truncated LipL32 (tLipL32) was designed to contain the region (87-188th amino acid). The tLipL32 was compared between two recombinant expression hosts Escherichia coli and Pichia pastoris in ELISA. With field rat sera, tLipL32 expressed by P. pastoris (tLipL32p) had high antigenicity without background reactions, while tLipL32 expressed by E. coli (tLipL32e) showed high background reactions, which were reduced by pre-adsorption of sera with E. coli. To evaluate tLipL32-ELISA, field rat sera were tentatively divided into a Leptospira infection positive (12 sera) and a negative group (12 sera) based on the results from flaB gene PCR of kidney samples and WB with whole Leptospira cell. Consequently, the sensitivity of tLipL32p-ELISA for field rat sera was 83% . A similar result was obtained from tLipL32e-ELISA with adsorbed sera, (92%). However, sensitivity of tLipL32e-ELISA using sera without an adsorption treatment was 50%. Regardless of the expression host, tLipL32-ELISA had 100% specificity and sensitivity in experimentally infected laboratory rats. These results suggest that recombinant LipL32 expressed by P. pastoris is more applicable for serodiagnosis in field rats due to a lack of background reaction.

The Institute for the Achievement of Human Potential developed a device known as the Vehicle for Initial Crawling (VIC); the acronym is a tribute to the crawler's inventor, Hubert "Vic" Vykukal; is an effective crawling aid. The VIC is used by brain injured children who are unable to crawl due to the problems of weight-bearing and friction, caused by gravity. It is a rounded plywood frame large enough to support the child's torso, leaving arms and legs free to move. On its underside are three aluminum discs through which air is pumped to create an air-bearing surface that has less friction than a film of oil. Upper side contains the connection to the air supply and a pair of straps which restrain the child and cause the device to move with him. VIC is used with the intent to recreate the normal neurological connection between brain and muscles. Over repetitive use of the device the child develops his arm and leg muscles as well as coordination. Children are given alternating therapy, with and without the VIC until eventually the device is no longer needed.

We determined the humoral immune response to outer surface protein C (OspC) of Borrelia burgdorferi in patients with early or late manifestations of Lyme disease and investigated the use of this antigen in the serodiagnosis of early infection. The ospC gene from the low-passage human isolate 297, a North American B. burgdorferi strain, was used to make a recombinant maltose-binding protein (MBP)-OspC fusion protein for serologic tests. This gene showed 84 to 85% nucleotide sequence identity and 76 to 79% amino acid identity with ospC of B. burgdorferi B31 and 2591. The antibody responses to MBP-OspC were determined in serial sera from 15 patients with Lyme disease who were monitored for 4 to 12 years of illness, in single-serum samples from 189 patients with early or late manifestations of the disorder, and in serum samples from 106 control patients. Early in the infection, patients with erythema migrans or meningitis commonly had weak to strong immunoglobulin M (IgM) responses to OspC and sometimes weak to moderate IgG responses. Months to years later, weak to strong IgG reactivity with this protein was often apparent in patients with arthritis, but this response was weak or absent in patients with chronic neuroborreliosis. When acute- and convalescent-phase serum samples from patients with erythema migrans were tested for reactivity against MBP-OspC, the sensitivity of the IgM test was 73% and the specificity was 98%, with either enzyme-linked immunosorbent assay (ELISA) or Western blotting. We conclude that the majority of patients with Lyme disease have a prominent IgM response to OspC early in the illness, which is often followed by a prominent IgG response in patients with arthritis. For the serodiagnosis of early infection, the sensitivity and specificity of IgM ELISA and Western blotting were comparable or slightly improved when MBP-OspC was used as the antigen compared with tests in which spirochetal lysates were used.

Leptospirosis is a zoonotic disease caused by pathogenic spirochetes of the genus Leptospira, causing febrile infection characterized by multi-organ failure in humans and animals. Leptospiral Ig-like protein B (LigB) is a surface-expressed antigen that mediates host cell invasion or attachment. In this study, N-terminal conserved region of LigB protein (46 kDa) was evaluated for its diagnostic potential to detect anti-leptospiral antibodies in the sera of various animal species. Dot blot analysis revealed immunoreactivity of Leptospira-positive sera of cattle, buffalo, dog, sheep and goat to purified LigB protein. We have analyzed 1126 bovine serum samples, collected from Northern and Eastern part of India, by microscopic agglutination test (MAT) and recombinant LigB (rLigB) based ELISA and latex agglutination test (LAT). The sensitivity of rLigB based ELISA for 554 MAT positive sera was 96.9% and the specificity with 572 MAT negative sera was 91.08% whereas LAT showed sensitivity and specificity of 93.68% and 92.31%, respectively. Kappa values of 0.879 and 0.860 for recombinant antigen based ELISA and LAT indicate excellent agreement with the gold standard serological test, MAT, for the detection of anti-leptospiral antibodies in sera. Further, LAT based on rLigB antigen is a simple and rapid test, suitable for serodiagnosis of leptospirosis under field conditions, owing to its portability and longer shelf life.

Various serological tests were used for the diagnosis of glanders in the past but still complement fixation test (CFT) is the internationally prescribed test for trading equines. A new immunoblot (IB) technique has recently been introduced to overcome the well known shortcomings of CFT i. e. a considerable number of false positive and negative results and anticomplementary effects of sera. The objective of this study was the comparative evaluation of two glanders CFT antigens commercially available at Central Veterinary Institute ofWageningen UR, Lelystad, NL (CIDC) and at c.c.pro GmbH, Oberdorla, DE (c.c.pro) in a glanders endemic area regarding specificity and sensitivity. A total of 1678 serum samples from the endemic region (Province Punjab, Pakistan) and a non-endemic area (Germany) were analysed. All sera tested positive or suspicious with CFT were analysed by the confirmatory IB to exclude CFT false positive results. Both CFT antigens showed 100% sensitivity. The use of CIDC or c.c.pro antigen resulted in specificities of 77.45% or 75.71% for sera from endemic area and 93.75% or 94.79% for sera from non-endemic areas, respectively. The results demonstrate the different performances of identical tests in different epidemiologically settings. Based on these results, the combined use of CFT and IB is highly suggestive for the serodiagnosis of glanders. Good agreement was calculated between CFT (using either c.c.pro or CIDC antigen) and immunoblot.

The aim of the study was to evaluate the usefulness of 3 chimeric Toxoplasma gondii antigens, P35-MAG1, MIC1-ROP1 and MAG1-ROP1, in the serodiagnosis of an acute toxoplasmosis in humans. Proteins were produced as fusion proteins containing His tags ends and then further purified by metal affinity chromatography. Their application for the diagnosis of recently acquired T. gondii infection was tested in IgG and IgM enzyme-linked immunosorbent assays (ELISAs). At 100%, 77.3%, and 86.4%, respectively, the reactivity of the IgG ELISA using P35-MAG1, MIC1-ROP1, and MAG1-ROP1 for sera from patients where acute toxoplasmosis was suspected was significantly higher than for the samples from people with a chronic infection, at 26.2%, 36.1%, and 32.8%, respectively. Moreover, P35-MAG1, MIC1-ROP1, and MAG1-ROP1 detected IgM antibodies with a reactivity at 81.8%, 72.7%, and 59.1%, respectively. The results presented in the article show that, particularly, P35-MAG1 may be useful in the preliminary detection of recent T. gondii infection.

Objective: To explore the serodiagnosis of hydatid cyst in human using different antigens of sheep (hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex) by ELISA and compares this result with commercial human ELISA kit. Methods: One hundred blood samples from patients with history of severe abdominal pain and eosinophilia were obtained. Ten serum samples were obtained from surgically and pathologically confirmed cystic echinococcosis patients from Mashhad university hospital as positive control and 5 serum samples from infant under one year old as negative control. Blood samples were centrifuged at 3 000íg at 20 ℃ for 15 min and sera were stored at -20 ℃. First, these samples were tested for the presence of antibody by commercial human ELISA. Then, ELISA was developed on microplates coated with hydatid fluid, Somatic and Excretory/secretory antigens of protoscolex of sheep. Results: The results of this study as analyzed by Kappa test showed that, hydatid fluid antigen could be used as a precise source of detection in indirect ELISA test. Conclusions: Hydatid fluid in comparison with Excretory-secretory and somatic antigens showed more compatibility agreement in kappa test which can be used for further studies in development of any ELISA test for diagnosis of human hydatidosis.

Full Text Available Thermostabilizing effect of heavy water (D2O or deuterium oxide has been demonstrated previously on several enzymes and vaccines like oral poliovirus vaccine and influenza virus vaccine. In view of the above observations, effect of heavy water on in situ thermostabilization of recombinant p26 protein on enzyme-linked immunosorbent assay (ELISA for serodiagnosis of equine infectious anemia virus (EIAV infection was investigated in the present study. The carbonate-bicarbonate coating buffer was prepared in 60% and 80% D2O for coating the p26 protein in 96-well ELISA plate and thermal stability was examined at 4°C, 37°C, 42°C, and 45°C over a storage time from 2 weeks to 10 months. A set of positive serum (n=12 consisting of strong, medium, and weak titer strength (4 samples in each category and negative serum (n=30 were assessed in ELISA during the study period. At each time point, ELISA results were compared with fresh plate to assess thermal protective effect of D2O. Gradual increase in the stabilizing effect of 80% D2O at elevated temperature (37°C < 42°C < 45°C was observed. The 80% D2O provides the thermal protection to rp26 protein in ELISA plate up to 2 months of incubation at 45°C. The findings of the present study have the future implication of adopting cost effective strategies for generating more heat tolerable ELISA reagents with extended shelf life.

VlsE, the variable surface antigen of Borrelia burgdorferi, contains an immunodominant conserved region named IR(6). In the present study, the diagnostic performance of a peptide enzyme-linked immunosorbent assay (ELISA) based on a 26-mer synthetic peptide (C(6)) with the IR(6) sequence was explored. Sensitivity was assessed with serum samples (n = 210) collected from patients with clinically defined Lyme disease at the acute (early localized or early disseminated disease), convalescent, or late disease phase. The sensitivities for acute-, convalescent-, and late-phase specimens were 74% (29 of 39), 85 to 90% (34 of 40 to 35 of 39), and 100% (59 of 59), respectively. Serum specimens from early neuroborreliosis patients were 95% positive (19 of 20), and those from an additional group of patients with posttreatment Lyme disease syndrome yielded a sensitivity of 62% (8 of 13). To assess the specificity of the peptide ELISA, 77 serum samples from patients with other spirochetal or chronic infections, autoimmune diseases, or neurologic diseases and 99 serum specimens from hospitalized patients in an area where Lyme disease is not endemic were examined. Only two potential false positives from the hospitalized patients were found, and the overall specificity was 99% (174 of 176). Precision, which was assessed with a panel of positive and negative serum specimens arranged in blinded duplicates, was 100%. Four serum samples with very high anti-OspA antibody titers obtained from four monkeys given the OspA vaccine did not react with the C(6) peptide. This simple, sensitive, specific, and precise ELISA may contribute to alleviate some of the remaining problems in Lyme disease serodiagnosis. Because of its synthetic peptide base, it will be inexpensive to manufacture. It also will be applicable to serum specimens from OspA-vaccinated subjects.
Full Text Available AbstractBackground and Purpose: According to the previous studies, Toxoplasma gondii excreted / secreted antigens (E/SA appear to be suitable marker for serodiagnosis of toxoplasmosis. Most of the previous studies used whole E/SA. The present study, was carried out to evaluate the ELISA method using E/SA components from Toxoplasma gondii for the diagnosis of toxoplasmosis.Materials and Methods: Components obtained by incubation of tachiziotes at RPMI-1640 culture medium were purified by Ion exchange chromatogeraphy and fractions were analyzed by native-PAGE electrophoresis. Forty noninfected rats were injected as IP with 4×106 Toxoplasma tachyzoites and their serum samples were collected at 8, 15, 22 and 60 days after infection then were tested by dye-test. Based on these results the sera of 15 and 60 days were selected and tested by ELISA using E/SA.Results: Second fraction of chromatography was selected as antigens. The cut-off point of ELISA with 99% confidence was found to be 0.41. Optical density of all sera samples of 15 and 3 of 60 days after infection and 2 negative sera were over the test cut-off. Therefore sensitivity and specificity of the method were determined to be 100% and 91% respectively.Conclusion: These results indicated that the second fraction of Ion exchange chromatography of Toxoplasma E/SA under these conditions may be useful tool for the serediagnosis and differentiation of acute and chronic phases of toxoplasmosis.

CHINA's first HIV positive diagnosis was in 1985, the victim an ArgentineAmerican. At that time most Chinese,medical workers included, thought of AIDS as a phenomenon occurring outside of China. Twenty years later, the number of HIV/AIDS patients has risen alarmingly. In 2003, the Chinese Ministry of Health launched an AIDS Epidemiological Investigation across China with the support of the WHO and UN AIDS Program. Its results show that there are currently 840,000 HIV carriers, including 80,000 people with full-blown AIDS, in 31 Chinese provinces, municipalities and autonomous regions. This means China has the second highest number of HIV/AIDS cases in Asia and 14th highest in the world. Statistics from the Chinese Venereal Disease and AIDS Prevention Association indicate that the majority of Chinese HIV carriers are young to middle aged, more than half of them between the ages of 20 and 29.

The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems.
Full Text Available Abstract Background The OmcB protein is one of the most immunogenic proteins in C. trachomatis and C. pneumoniae infections. This protein is highly conserved leading to serum cross reactivity between the various chlamydial species. Since previous studies based on recombinant proteins failed to identify a species specific immune response against the OmcB protein, this study evaluated an in silico predicted specific and immunogenic antigen from the OmcB protein for the serodiagnosis of C. trachomatis infections. Results Using the ClustalW and Antigenic programs, we have selected two predicted specific and immunogenic regions in the OmcB protein: the N-terminal (Nt region containing three epitopes and the C-terminal (Ct region containing two epitopes with high scores. These regions were cloned into the PinPoint Xa-1 and pGEX-6P-1 expression vectors, incorporating a biotin purification tag and a glutathione-S-transferase tag, respectively. These regions were then expressed in E. coli. Only the pGEX-6P-1 has been found suitable for serological studies as its tag showed less cross reactivity with human sera and was retained for the evaluation of the selected antigens. Only the Ct region of the protein has been found to be well expressed in E. coli and was evaluated for its ability to be recognized by human sera. 384 sera were tested for the presence of IgG antibodies to C. trachomatis by our in house microimmunofluorescence (MIF and the developed ELISA test. Using the MIF as the reference method, the developed OmcB Ct ELISA has a high specificity (94.3% but a low sensitivity (23.9. Our results indicate that the use of the sequence alignment tool might be useful for identifying specific regions in an immunodominant antigen. However, the two epitopes, located in the selected Ct region, of the 24 predicted in the full length OmcB protein account for approximately 25% of the serological response detected by MIF, which limits the use of the developed ELISA

Toxoplasma gondii infects all warm-blooded animals including humans, causing serious public health problems and great economic loss in the animal husbandry. Commonly used serological tests for diagnosis of toxoplasmosis involve preparation of whole Toxoplasma lysate antigen (TLA) from tachyzoites. The production of this antigen is associated with high costs and lengthy preparation and the possibility of staff infection. There are also some difficulties in the standardization of such tests. One approach in order to improve the diagnosis of T. gondii infection is to use recombinant chimeric antigens in place of the TLA, which was confirmed by studies in the serodiagnosis of toxoplasmosis in humans. In this paper, we assess, for the first time, the diagnostic utility of five T. gondii recombinant chimeric antigens (MIC1-MAG1-SAG1S, SAG1L-MIC1-MAG1, SAG2-GRA1-ROP1S, SAG2-GRA1-ROP1L, and GRA1-GRA2-GRA6) in immunoglobulin G (IgG) enzyme-linked immunosorbent assays (IgG ELISAs) with sera from three different groups of livestock animals (horses, pigs, and sheep). The reactivity of individual chimeric antigens was analyzed in relation to the results obtained in IgG ELISAs based on a mixture of three antigens (M1: rSAG1+rMIC1+rMAG1, M2: rSAG2+rGRA1+rROP1, and M3: rGRA1+rGRA2+rGRA6) and referenced to TLA. All chimeric antigens were characterized by high specificity (100%), and the sensitivity of the IgG ELISAs based on chimeric antigens was variable (between 28.4% and 100%) and mainly dependent on the animal species. The chimeric antigens were generally more reactive than mixtures of three antigens. The most effective for the diagnosis of toxoplasmosis was SAG2-GRA1-ROP1L, which can detect specific anti-T. gondii antibodies in 100%, 93.8%, and 100% of positive serum samples from horses, pigs, and sheep, respectively. The present study shows that recombinant chimeric antigens can be successfully used to diagnose T. gondii infection in farm animals, and can replace the commonly

World political aspects and the example of Australia as a national political response to AIDS are presented. Global policy on AIDS is influenced by the fact that the AIDS epidemic is the 1st to be largely predictable, that long lag times occur between intervention and measurable events, and by the prompt, professional leadership of WHO, lead by Dr. J. Mann. WHO began a Global Programme on AIDS in 1987, modelled on the responses of Canada and Australia. A world summit of Ministers of Health was convened in January 1988. These moves generated a response qualified by openness, cooperation, hope and common sense. The AIDS epidemic calls for unprecedented involvement of politicians: they must coordinate medical knowledge with community action, deal with public fear, exert strong, rational leadership and avoid quick, appealing counterproductive responses. 3 clear directions must be taken to deal with the epidemic: 1) strong research and education campaigns; 2) close contact with political colleagues, interest groups and the community; 3) a national strategy which enjoins diverse interest groups, with courage, rationality and compassion. In Australia, the AIDS response began with the unwitting infection of 3 infants by blood transfusion. A public information campaign emphasizing a penetrating TV ad campaign was instituted in 1987. Policy discussions were held in all parliamentary bodies. The AIDS epidemic demands rapid, creative responses, a break from traditions in health bureaucracy, continual scrutiny of funding procedures and administrative arrangements. In practical terms in Australia, this meant establishing a special AIDS branch within the Health Advancement Division of the Community Health Department. AIDS issues must remain depoliticized to defuse adversary politics and keep leaders in a united front.

Fifty-two patients with pulmonary complications of acquired immunodeficiency syndrome (AIDS) were studied over a 3-year period. The vast majority of the patients were homosexual; however, a significant number were intravenous drug abusers. Thirteen different organisms were noted, of which Pneumocystis carinii was by far the most common. Five patients had neoplasia. Most patients had initial abnormal chest films; however, eight patients subsequently shown to have Pneumocystis carinii pneumonia had normal chest films. A significant overlap in chest radiographic findings was noted among patients with different or multiple organisms. Lung biopsy should be an early consideration for all patients with a clinical history consistent with the pulmonary complications of AIDS. Of the 52 patients, 41 had died by the time this report was completed.

Full Text Available HIV infection and AIDS is increasingly becoming a major public health problem in our country. Currently, the reported cases represent only the 'tip of the iceberg' of the problem. In view of the fact that no cure or vaccine for the disease has yet been found, spreading knowledge and removing misconceptions is about the only way that AIDS can be effectively tackled.This handbook, developed by Prof. Shankar Chowdhury and associates, seeks to address all levels of medical and non-medical AIDS workers, as well as the layman. It deals with topics ranging from biology of the virus, symptoms and transmission of disease, to prevention, counselling for infected persons and action plan for AIDS education.The biology of the virus and the immune system is described in simple terms, as well as methods of testing for HIV, and what these test results mean. The progression of disease in adults and children, development of symptoms, diagnostic criteria for AIDS, treatment and outcome of disease is dealt with. How AIDS spreads between people, and the health risk for health workers and families is examined. The various ways in which transmission of HIV can be prevented is looked at in detail, including public health measures, national and internatonal action, and ethical and human rights issues involved.

Around the world, more and more women--principally poor women of color--are being diagnosed with and are dying of AIDS, the acquired immune deficiency syndrome. Yet, effective and appropriate prevention programs for women are sorely missing from the global program to control AIDS. To help us understand why this gap exists, and what we must do to close it, the three articles in this issue focus on women and AIDS. Examining the situation in such countries as Zimbabwe and South Africa, as well as in other economically underdeveloped and developed regions, the authors argue that women with the least control over their bodies and their lives are at greatest risk of acquiring AIDS. For example, the high rate of infection among women in Africa cannot be understood apart from the legacy of colonialism (including land expropriation and the forced introduction of a migrant labor system) and the insidious combination of traditional and European patriarchal values. Only by recognizing the socioeconomic and cultural determinants of both disease and sexual behavior, and only by incorporating these insights into our AIDS prevention programs, will we be able to curb the spread of this lethal disease.
Numerous cultural practices and attitudes in Africa represent formidable obstacles to the prevention of the further spread of acquired immunodeficiency syndrome (AIDS). Polygamy and concubinage are still widely practiced throughout Africa. In fact, sexual promiscuity on the part of males is traditionally viewed as positive--a reflection of male supremacy and male sexual prowess. The disintegration of the rural African family, brought about by urbanization, the migrant labor system, and poverty, has resulted in widespread premarital promiscuity. Contraceptive practices are perceived by many as a white conspiracy aimed at limiting the growth of the black population and thereby diminishing its political power. Condom use is particularly in disfavor. Thus, AIDS prevention campaigns urging Africans to restrict the number of sexual partners and to use condoms are unlikely to be successful. Another problem is that most Africans cannot believe that AIDS is sexually linked in that the disease does not affect the sex organs as is the case with other sexually transmitted diseases. The degree to which African governments are able to allocate resources to AIDS education will determine whether the epidemic can be controlled. Even with a massive outpouring of resources, it may be difficult to arouse public alarm about AIDS since Africans are so acclimated to living with calamities of every kind.

Between January 1984 and December 1987 a total of 178 AIDS cases were reported to the Colombian Ministry of Health. The location of these cases suggests that the human immunodeficiency virus (HIV) is widely distributed in Colombia. Most of those afflicted (97%) have been adult males. HIV seroprevalence studies of selected population groups revealed the highest antibody prevalence (5.65% in females, 22.5% in males) among individuals involved in high-risk behaviors who participated in a free AIDS testing program. High prevalences (from 0.6% to 3.9% in females, and 14.6% to 15.9% in males) were also found in patients (primarily female prostitutes and male homosexuals) attending clinics for sexually transmitted diseases in several urban areas. The number of AIDS cases in Colombia has doubled or tripled annually since reporting began in 1984, a pattern similar to that observed worldwide.

A study about mortality by AIDS had been undertaken since July 1st 1983, in the Service of Information on Medical causes of Death (INSERM SC8), which is in charge of developing mortality statistics in France. From July 1st 1983 to September 30th 1985, 243 deaths due to AIDS were recorded. Only the cases where this diagnosis was clearly mentioned were selected; more than 90% were notified by hospitals and mainly by highly specialized services. The number of deaths, which was low and varied rather irregularly at the beginning, then increased by successive stages. The first year, during which a tenth of deaths was recorded every three months, was followed by a great increase, doubling, then tripling the initial numbers. Lastly, a second and sudden rise occurred during the third trimester of 1985, the trimestrial number of deaths due to AIDS reaching 80.

AIDS associated malignancies (ARL) is a major complication associated with AIDS patients upon immunosuppression.Chronically immunocompromised patients have a markedly increased risk of developing lymphoproliferative disease. In the era of potent antiretrovirals therapy (ARV), the malignant complications due to HIV- 1 infection have decreased in developed nations where ARV is administered, but still poses a major problem in developing countries where HIV- 1incidence is high and ARV is still not yet widely available. Even in ARV treated individuals there is a concern that the prolonged survival of many HIV- 1 carriers is likely to eventually result in an increased number of malignancies diagnosed.Malignancies that were found to have high incidence in HIV-infected individuals are Kaposi's sarcoma (KS), Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The incidence of NHL has increased nearly 200 fold in HIV-positive patients, and accounts for a greater percentage of AIDS defining illness in the US and Europe since the advent of HAART therapy. These AIDS related lymphomas are distinct from their counterparts seen in HIV- 1 seronegative patients.For example nearly half of all cases of ARL are associated with the presence of a gamma herpesvirus, Epstein Barr virus (EBV) or human herpesvirus-8 (HHV-8)/Kaposi's sarcoma associated herpesvirus (KSHV). The pathogenesis of ARLs is complex. B-cell proliferation driven by chronic antigenemia resulting in the induction of polyclonal and ultimately monoclonal lymphoproliferation may occur in the setting of severe immunosuppression.

Two cases of post-transfusional AIDS in two premature babies who received blood of the same seropositive donor, are reported. The risk of the susceptibility to HIV infection of these patients, in relation to the immaturity of immune system and to the transfusional treatment often necessary in premature newborns, is stressed.

Tests to detect serum antibody to human T-lymphotropic virus type III (HTLV-III), based on an enzyme-linked immunosorbent assay (ELISA) that uses whole disrupted HTLV-III virus antigens, are now commercially available in the US. Recent surveys of groups at high risk for acquired immunodeficiency syndrome (AIDS) have found that 22-65% of homosexual men, 87% of active intravenous drug users, 56-72% of hemophiliacs, and 35% of women who were sexual partners of men with AIDS have had postitive ELISA tests compared with fewer than 1% of those with no known risk factors. A positive ELISA test could be due to subclinical infection, immunity, or cross-reactivity with other viral antigens. Laboratory error can also produce false positive results. Thus, it is recommended that the ELISA test be repeated at least once on all seropositive specimens before the result is reported to the patient. The western blot test appears to be more specific and less sensitive than the ELISA. Studies of asymptomatic seropositive homosexual men followed for 2-5 years have found that over 50% remain asymptomatic, 5-19% develop full blown AIDS, and 25% develop signs suggestive of the AIDS-related complex. Asymptomatic patients with positive ELISA tests should be made aware of early signs and symptoms of AIDS. Other data suggest that seropositive patients have the HTLV-III virus in their blood, semen, and/or saliva and can transmit the infection. Precautions to prevent transmission, such as the use of condoms, should be taken by such patients. Physicians should be sensitive to the fear and anxiety that a positive ELISA test will create.

Does perceived corruption in recipient countries reduce support for foreign aid in donor countries? This under-explored yet salient question is examined using the 2009 Eurobarometer survey for the 27 EU countries. We suggest that perceived corruption can cause aid fatigue but that this relationship...... is highly contextualized. The results show that perceptions about corruption in developing countries reduce overall support for aid among respondents in donor countries. However, this effect is mitigated by country and contextual-level effects and different understandings of what we call the “aid-corruption...... paradox,” namely that the need for foreign aid is often the greatest in corrupt environments. Three different dynamics of the aid-corruption paradox influence support for aid: moral, pragmatic, and strategic understandings. In EU-15 countries, the effect of perceived corruption in recipient states on aid...

Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

Full Text Available Tuberculosis (TB remains uniquely important among acquired immune deficiency syndrome (AIDS-associated opportunistic infections: it presents the greatest public health hazard worldwide, is the most readily curable, and is largely preventable with existing means. Given the expanding pool of human immunodeficiency virus (HIV seropositive persons, particularly in developing nations where Mycobacterium tuberculosis remains a leading health problem, one can expect a continued rise in TB cases during the 1990s. Global efforts to eliminate TB are now inextricably entwined with the effectiveness of measures to curtail the HIV epidemic. Mycobacterium avium complex infection, currently an intractable late complication of aids, may increase in clinical importance as success in managing other opportunistic infections and HIV disease itself improves. Understanding of the pathogenesis and management of mycobacterial diseases should increase rapidly given the renewed research spurred on by the advent of HIV.

We retrospectively reviewed our series of 35 pulmonary mycosis in patients with AIDS, observed from 1987 to 1999, to correlate the imaging and pathologic findings. We further evaluated the frequency of fungal pneumonia before and after the use of a highly active antiretroviral therapy (HAART). Early recognition of pulmonary mycosis is imperative in these patients and improved survival can be achieved with early CT detection and prompt institution of high-dose antifungal therapy.

Global health analysts have debated whether donor prioritization of HIV/AIDS control has lifted all boats, raising attention and funding levels for health issues aside from HIV/AIDS. We investigate this question, considering donor funding for 4 historically prominent health agendas-HIV/AIDS, health systems strengthening, population and reproductive health, and infectious disease control-over the decade 1998-2007. We employ funding data from the Development Assistance Committee of the Organization for Economic Cooperation and Development, which tracks donor aid. The data indicate that HIV/AIDS may have helped to increase funding for the control of other infectious diseases; however, there is no firm evidence that other health issues beyond the control of infectious diseases have benefited. Between 1998 and 2007, funding for HIV/AIDS control rose from just 5.5% to nearly half of all aid for health. Over the same period, funding for health systems strengthening declined from 62.3% to 23.9% of total health aid and that for population and reproductive health declined from 26.4% to 12.3%. Also, even as total aid for health tripled during this decade, aid for health systems strengthening largely stagnated. Overall, the data indicate little support for the contention that donor funding for HIV/AIDS has lifted all boats.

Sub-Saharan Africa is the epicenter of the HIV/AIDS epidemic, and in this issue of the Journal, seven authors discuss the moral, social and medical implications of having 70% of those stricken living in this area. Anton A. van Niekerk considers complexities of plague in this region (poverty, denial, poor leadership, illiteracy, women's vulnerability, and disenchantment of intimacy) and the importance of finding responses that empower its people. Solomon Benatar reinforces these issues, but also discusses the role of global politics in sub-Saharan Africa, especially discrimination, imperialism and its exploitation by first world countries. Given the public health crisis, Udo Schüklenk and Richard E. Ashcroft defend compulsory licensing of essential HIV/AIDS medications on consequentialist grounds. Keymanthri Moodley discusses the importance of conducting research and the need to understand a moderate form of communitarianism, also referred to as "ubuntu" or "communalism", to help some Africans understand research as an altruistic endeavour. Godfrey B. Tangwa also defends traditional African values of empathy and ubuntu, discussing how they should be enlisted to fight this pandemic. Loretta M. Kopelman criticizes the tendency among those outside Africa to dismiss the HIV/AIDS pandemic, attributing one source to the ubiquitous and misguided punishment theory of disease. The authors conclude that good solutions must be cooperative ventures among countries within and outside of sub-Saharan Africa with far more support from wealthy countries.

Britain has longed followed a disease-control strategy for providing aid in the health sector to developing, low-income countries. Given, however, the high level of waste upon tertiary care and specialized medicine in current health programs of low-income countries as documented by the World Bank; the poor performance of existing general government hospitals and clinics; and the poor image of Third World health systems in the eyes of Western officials and government ministers, the chief health advisor of the Overseas Development Administration has called for a drastic redirection of policy toward development aid. Specifically, a shift away from a specific-disease control approach toward an overall, sweeping reform of the health sector in developing countries is urged. The level of waste needs to be reduced and more attention given to the poor. Unless such changes result, government ministers will grow increasingly reluctant to provide tangible aid to the health sectors of countries in need. The availability of such funds invested in effective, well-managed health programs will grow more critical to health in the Third World as populations shift away from communicable disease morbidity and mortality toward illnesses which are of a more noncommunicable nature such as stroke and cancer.

An ELISA for the detection of anti-HEV using synthetic peptideantigens was developed. The synthetic antigens were encoded by OFR2 and OFR3 genes of HEV. The purpose of this study was to determine the applicability of the synthetic antigens in the serodiagnosis of hepatitis E. The anti-HEV detection using synthetic antigens was carried out in 47 healthy subjects and 89 patients with acute or chronic viral hepatitis. The results showed that the positive rate of anti-HEV-IgG in healthy subjects was 4.2%(2/47), and no IgM antibody to HEV was found. The positive rates of IgG and IgM antibodies to HEV in the hepatitis patients were 8.9% and 10% respectively. In addition, we compared the detecting efficacy of the synthetic antigens with that of the market reagent in 57 serum samples, the total coincident rate was 87.7% (50/57). All of the results accorded with the literatures reported. This study suggests that the ELISA based on the synthetic peptide antigens was specific, sensitive and convenient in diagnosis of HEV infection, it can be widely used in both clinical and epidemiological reseaches.
The myths and prejudices that distort the reality and hide the true causes and effects of natural and social phenomena related to sexuality have a fertile ground in AIDS, given its obvious link to sex. The alarming spread of AIDS has been 1 result of these myths and prejudices. Human beings are sexual by nature; genital organs determine sex and also induce sexual behavior. It is by not fairly well accepted that an individual's sexuality exists from birth. Puberty usually begins at 12-16 years for both sexes. The physical changes of puberty terminate in the ability of the female to conceive and the male to procreate. The sexual excitation of adolescents resulting from production of various hormones can only be eliminated by some type of sexual satisfaction or sublimation. Sexuality, according to Freud, is an organizing principle of the personality. The sexual organs exist not merely for reproduction but to provide pleasure. Puberty signifies entry into active sex life. But the ideological structure of society, perpetuated by the family, schools, religion, the mass media, and other social institutions, sends confused signals to adolescents, requiring abstinence and virginity until marriage for women while encouraging sexual adventures for men. Adolescents are confronted by their new sexual feelings in the midst of a virtual bombardment of visual sexual stimuli from the mass media. It becomes impossible for adolescents to satisfy the requirements of appearances while also resolving the problems and pressures of their newly gained sexual maturity. Many adolescents become sexually active, and the problem is not to prevent sexual activity but to improve the conditions under which it occurs. Adolescents, lacking education and information about sex, begin their sex lives without protection. AIDS has now been added to the list of dire consequences that can result. A true sex education beginning in the home is needed to enable young people to develop healthy and full sex

Full Text Available This paper explores the significance of social relationships to two important stages in the process of sexual behavioral change in response to increased HIV/AIDS risk in rural Africa: the perceived risk of becoming HIV-infected through unprotected sexual intercourse and the preferred methods of protection either through sexual fidelity, or through condom use. The empirical analyses are based on cross-sectional data from the 'Kenyan Diffusion and Ideational Change Project' (KDICP which provides information about AIDS-related, ego-centered communication networks of Kenyan men and women. The results show that perceived risks, as well as preferred methods of protection against HIV-infection, depend in general on the prevailing perceptions and favored protective methods within personal communication networks. However, different influential network properties can be found. The risk-perceptions of women are shaped by strong relationships and cohesive network structures. Male's risk perception depends more on the number of risk-perceivers in their communication networks. Heterogeneous relationships of various kinds are influential on women's and men's probability of favoring sexual faithfulness as a method of protection against HIV-infection.

In response to concern over the perceived limited effectiveness of Department of Health and Social Security (UK) advertising campaigns to inform the public of the basic facts of Acquired Immunodeficiency Syndrome (AIDS), a prospective questionnaire study was undertaken in Southampton, England to test the effectiveness of government education prior to a January, 1987 government television/leaflet advertising campaign. 300 questionnaires about AIDS were mailed in December of 1986 to a sample drawn from electoral rolls. The response rate was 61%. Most of the questions were drawn from material covered in the campaign. The results seemed to indicate a small overall increase in knowledge about AIDS. Some changes from a June survey were noted, e.g.: more people were aware that AIDS is a virus for which there is no cure and that it is not readily transmitted by sharing washing, eating or drinking utensils; more people believed that the statement that women are at greater risk for catching AIDS is false. Respondents were generally favorable to the government's continued use of television, even with explicit language, and to its use of the schools, for AIDS education. Many were not aware of the dangers to intravenous drug users or of the symptoms of AIDS. Other surveys have shown an increasing knowledge of AIDS dangers. It is possible that television coverage of the problem will continue to be necessary, in order that less literate populations be reached. Further AIDS health education in general is needed.

Great interest is currently shown for the contribution of nutrition to optimize training and athletic performance, and a considerable debate exists about the potential ergogenic value of several dietary supplements. However, most of the products used by athletes do not provide sufficient scientific evidence regarding their efficacy in enhancing physical performance as well as their specificity of action and safety. For this reason, sport nutrition professionals need skills in evaluating the scientific value of papers and advertisements on ergogenic aids and supplements in order to support athletes in their choice. In the present chapter, the efficacy of some of the most popular supplements used by athletes and sport practitioners will be discussed. Particular attention will be devoted to amino acids and derivatives, caffeine and caffeinated energy drinks, and some antioxidants.
The National Health Service (NHS) is one of the largest employers in the world and, with 1.3 million staff, the biggest employer in Europe. With over three hundred different careers on offer (NHS 2015), the acquisition of skills and qualifications, through academic and clinical training, is an integral part of day-to-day life in the health service. As such, mentoring has become a significant feature in the preparation of healthcare professionals, to support students and ensure learning needs and experiences are appropriate to competency. This article examines the mentor's role, in relation to a teaching innovation designed to address students' identified learning needs to meet the requirements of the multi-professional learning and assessment in practice course NM6156. The effectiveness of the aids to learning will be assessed through an online quiz, and its usefulness will be analysed with reference to educational theories of learning and development.

Tourists traveling internationally lower their inhibitions and take greater risks than they would typically in their home cultures. Loneliness, boredom, and a sense of freedom contribute to this behavioral change. Some tourists travel internationally in search of sexual gratification. This motivation may be actively conscious or subconscious to the traveler. Billed as romantic with great natural beauty, Thailand, the Philippines, Brazil, the Dominican Republic, and Kenya are popular destinations of tourists seeking sex. The Netherlands and countries in eastern Europe are also popular. With most initial cases of HIV infection in Europe having histories of international travel, mass tourism is a major factor in the international transmission of AIDS. While abroad, tourists have sex with casual partners, sex workers, and/or other tourists. Far from all tourists, however, carry and consistently use condoms with these partners. One study found female and non white travelers to be less likely than Whites and males to carry condoms. The risk of HIV infection increases in circumstances where condoms are not readily available in the host country and/or are of poor quality. Regarding actual condom use, a study found only 34% of sex tourists from Switzerland to consistently use condoms while abroad. 28% of men in an STD clinic in Melbourne, Australia, reported consistent condom use in sexual relations while traveling in Asia; STDs were identified in 73% of men examined. The few studies of tourists suggest that a significant proportion engage in risky behavior while traveling. HIV prevalence is rapidly increasing in countries known as destinations for sex tourism. High infection rates are especially evident among teenage sex workers in Thailand. Simply documenting the prevalence of risky behavior among sex tourists will not suffice. More research is needed on travelers and AIDS with particular attention upon the motivating factors supporting persistent high-risk behavior.

This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.
Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Conclusions. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

A promilitary coalition began to govern Thailand in March 1992. It reduced the budget for the original proposed national AIDS awareness campaign from 30 million British pounds to almost 15 million British pounds. The Ministry of Health professed that the campaign had exaggerated the problem of AIDS in Thailand and had damaged tourism. Yet prodemocracy demonstrations in Bangkok in which troops killed many protesters restored the politicians who started the AIDS campaign to power in May 1992. There were to remain in power until new elections in September 1992. In July, the Minister of Health, Mechai Viravaidya, said he would step down if the government did not completely restore the 30 million British pounds for the AIDS campaign. It then increased the budget to almost that amount. Mr. Viravaidya initiated Thailand's open policy on the AIDS crisis and was known as Mr. Condom. He claimed that at the present HIV prevalence rate, Thailand may have between 2-4 million HIV infected people by 2000. If the country would take on anti-AIDS efforts now, however, they could cut the spread of HIV by 75%. As of mid-1992, about 400,000 people living in Thailand were HIV positive. The AIDS campaign planned to sue the mass media to inform people about AIDS especially those in universities and schools and high risk occupational groups. The increasing number of construction workers in Bangkok and existing sex workers were a high risk occupational group. At the 2nd national seminar of AIDS, the Minister of Health reproached tourists who come to Thailand for its sex industry. He said that Thailand does not need the 1 billion British pounds they bring to Thailand annually, and Thais do not want their homeland to be referred to as the sex capital.
While Asia was the last region to be exposed to the global spread of HIV and AIDS, the incidence of HIV infection there is increasing fastest. The Asian Development Bank predicts mortality from AIDS will cause some town and village populations to begin declining by the year 2000. With an estimated 1 million people infected in India, and 400,000 in Thailand, these 2 countries are particularly exposed to the risk of epidemic HIV spread. In 5 years, more people may be affected by AIDS in India than anywhere else in the world. Concern over a growing presence of HIV is also merited for the Philippines, Indonesia, China, and the drug trade's Golden Triangle. The Second International Conference on AIDS in Asia and the Pacific in November 1992 stressed that AIDS no longer affects only homosexual and IV drug using populations. 50% of new infections worldwide in the first half of 1992 were among women, 65% of Thailand's AIDS cases are among heterosexuals, and 3-5% of Thailand's long-haul truck drivers have tested positive for HIV infection. HIV and AIDS robs economies and societies of their best workers. The immediate costs of caring for AIDS patients will pale next to the far greater losses to be realized in private sector economic productivity. Asia's more developed economies will probably be able to survive the epidemic, but small, poor countries like Laos will wilt. Prompt action must be taken to overcome public and religious ignorance and objections to promoting and using condoms throughout the region. For the first time, Beijing has organized an AIDS awareness conference for male homosexuals. Further, Singapore has implemented compulsory testing for lower-income foreign workers. Pakistan has even solicited educational assistance and support from Islamic religious leaders; similar action is being considered in Bangladesh.
Despite advances made in recent years in medical first aid, psychiatric intervention, survival training and equipment design, many people still perish quickly during and immediately following a disastrous event. In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

Full Text Available This work aims to explore some of the weaknesses that the international aid system presents for efficaciously operating in promoting development. For this, it adopts an institutionalapproach, attempting to investigate the problems of asymmetry in information that occur both in relationships between donor and receiver and within aid organisations. The analysis of these aspects leads the author to underscore the importance that learning processes have in enriching interventions in development; he also underscores the importance of the attitudes and aptitudes of the agents in fostering these processes of improvement in aid quality.

AIDS posters can be treated as material objects whose production, distribution and consumption varied across time and place. It is also possible to reconstruct and analyse the public health discourse at the time these powerful images appeared. More recently, however, these conventional historical approaches have been challenged by projects in literary and art criticism. Here, images of AIDS are considered in terms of their function in and for a new discursive regime of power centred on the human body and its visualization. How images of AIDS came to be understood in Western culture in relation to wider political and economic conditions redefines the historical task.

The central research problem of this project is the effective representation and display of surfaces, interpolating to given information, in three or more dimensions. In a typical problem, we wish to create a surface from some discrete information. If this information is itself on another surface, the problem is to determine a surface defined on a surface,'' which is discussed below. Often, properties of an already constructed surface are desired: such geometry processing'' is described below. The Summary of Proposed Research from our original proposal describes the aims of this research project. This Summary and the Table of Contents from the original proposal are enclosed as an Appendix to this Progress Report. The broad sweep from constructive mathematics through algorithms and computer graphics displays is utilized in the research. The wide range of activity, directed in both theory and applications, makes this project unique. Last month in the first Ardent Titan delivered in the State of Arizona came to our group, funded by the DOE and Arizona State University. Although the Titan is a commercial product, its newness requires our close collaboration with Ardent to maximize results. During the past year, four faculty members and several graduate research assistants have worked on this DOE project. The gaining of new professionals is an important aspect of this project. A listing of the students and their topics is given in the Appendix. The most significant publication during the past year is the book, Curves and Surfaces for Computer Aided Geometric Design, by Dr. Gerald Farin. This 300 page volume helps fill a considerable gap in the subject and includes many new results on Bernstein-Bezier curves and surfaces.

Full Text Available Rehabilitation of deaf individual is one of the important subjects that has attracted attention of many researchers during past centuries. Different opinions have been established in this direction. Electrophysiologic tests were established and developed parallel to developments in rehabilitation. Therefore, opinion of using electrophysiologic test for evaluation and fitting of hearing aid became gradually popular. Ultimately, the electrophysiologic tests are used in evaluation and fitting of hearing aid in two ways: 1-Direct way 2- Indirect way "nIn direct way aided ABR is obtained and special attention is paid to wave V. This technique has many difficulties. Inindirect way, electrophysiologic tests such, ECochG, OAE and ABR, AMLR, ALR and P300 and other objective tests are used, especially in infants and neonates for evaluating the state of hearing. Researches are continuing in this field. It is probable to have aided electrophysiologic responses with speech stimuli in near future.

As with affirmative action in the '70s, it is the big companies that have, in just the last 10 or 12 months, begun to address AIDS in the workplace. Their top executives have come to add such action to the list of management responsibilities. More employers of all sizes may join them, especially those that grasp the true role--and the non-role--of geography in the AIDS epidemic.

Full Text Available Abstract In the history of public health, HIV/AIDS is unique; it has widespread and long-lasting demographic, social, economic and political impacts. The global response has been unprecedented. AIDS exceptionalism - the idea that the disease requires a response above and beyond "normal" health interventions - began as a Western response to the originally terrifying and lethal nature of the virus. More recently, AIDS exceptionalism came to refer to the disease-specific global response and the resources dedicated to addressing the epidemic. There has been a backlash against this exceptionalism, with critics claiming that HIV/AIDS receives a disproportionate amount of international aid and health funding. This paper situations this debate in historical perspective. By reviewing histories of the disease, policy developments and funding patterns, it charts how the meaning of AIDS exceptionalism has shifted over three decades. It argues that while the connotation of the term has changed, the epidemic has maintained its course, and therefore some of the justifications for exceptionalism remain.

RATIONALE AND KEY POINTS: This article aims to help nurses to perform first aid in a safe, effective and patient-centred manner. First aid comprises a series of simple, potentially life-saving steps that an individual can perform with minimal equipment. Although it is not a legal requirement to respond to an emergency situation outside of work, nurses have a professional duty to respond and provide care within the limits of their competency. First aid is the provision of immediate medical assistance to an ill or injured person until definitive medical treatment can be accessed. First aid can save lives and it is essential that nurses understand the basic principles. REFLECTIVE ACTIVITY: Clinical skills articles can help update your practice and ensure it remains evidence based. Apply this article to your practice. Reflect on and write a short account of: 1. Your skill in performing first aid and any areas where you may need to extend your knowledge. 2. How reading this article will change your practice. Subscribers can upload their reflective accounts at: rcni.com/portfolio .
With a view to ensuring optimum use of the first-aid boxes on the CERN site, we should like to remind you of various changes introduced in March 2009: The TSO of the buildings concerned is responsible for the first-aid boxes, including checking their contents. First-aid boxes may be restocked ONLY at the CERN stores (SCEM No. 54.99.80). This is no longer possible at the Infirmary. The associated cost is charged to the Departments. First-aid boxes should be used only for mild injuries. All other cases should be referred to the Medical Service Infirmary (Bldg. 57 – ground-floor, tel. 73802) between 8.00 a.m. and 5.30 p.m. or to the Fire and Rescue Service (tel. 74444). N.B.: This information does not apply to the red emergency first-aid boxes in the underground areas or to the emergency kits for use in the event of being splashed with hydrofluoric acid.
Foreign aid has become closely connected to the development of democracy since the nineties. This paper analyses the democracy effects of aid accounting for this change in donors’ criteria.

The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

The political constraints slowing the battle against AIDS in Africa are getting AIDS on the public agenda, integrating the international community into the AIDS policy-making agenda and cultural barriers in national AIDS strategies. Policy making in most Africa is bureaucratic rather than democratic, so whether AIDS is a government priority depends largely on perception of AIDS risk by the leaders. In Zambia and Uganda, AIDS is a concern because it affects the ethnic group or family in power, while in Tanzania and Kenya, AIDS is associated with minority or "high risk" groups. The domination of AIDS agenda setting within nations in Africa by international donors and non-governmental organizations is a problem, made more severely severed by sensitivity of Africans who perceive research as a foreign effort to prove that AIDS originated there. Foreign domination is also detrimental because it prevents localities from becoming committed to AIDS interventions. Cultural barriers against effective interventions are similar to those in Western countries: AIDS is seen as a disease of shame affecting immoral people. In addition, the prevalent concept of fatalism defeats the Western insistence on intervention and strategies. Furthermore, women who are largely dependent on men cannot insist on preventive behavior, not do they have organizations in place to protect their rights. Finally, the concepts of behavioralism, and learning new behaviors for person-centered reasons, are foreign to much of Africa.
This is the first comprehensive book to present, in English, the multicriteria methodology for decision aiding In the foreword the distinctive features and main ideas of the European School of MCDA are outlined The twelve chapters are essentially expository in nature, but scholarly in treatment Some questions, which are too often neglected in the literature on decision theory, such as how is a decision made, who are the actors, what is a decision aiding model, how to define the set of alternatives, are discussed Examples are used throughout the book to illustrate the various concepts Ways to model the consequences of each alternative and building criteria taking into account the inevitable imprecisions, uncertainties and indeterminations are described and illustrated The three classical operational approaches of MCDA synthesis in one criterion (including MAUT), synthesis by outranking relations, interactive local judgements, are studied This methodology tries to be a theoretical or intellectual framework dire...

Bare et al (2015 Environ. Res. Lett. 10 125010) ask an important question: is international conservation enough? Since the 1990’s international conservation donors have spent over 3.4 billion on biodiversity conservation related projects in sub-Saharan Africa. Both donors and recipients have a right to know if this is effective. Surprisingly, this question is rarely asked. It is a difficult question—involving many rival social, environmental, and economic explanations. Bare, Kauffman and Miller uncover some interesting associations, supporting existing hypotheses and proposing their own: that conservation aid alone is insufficient to mitigate drivers of deforestation (and in some cases may even exacerbate forest loss). This controversial result warrants further investigation—but what is needed now is nuance and robustness in further analyses, to have more confidence in the critique and it’s implications for international conservation aid.

Full Text Available Management of any problem starts with an accurate diagnosis and this is not different in the field of endodontics. The diagnosis of dental pulp status should be seen as a synthesis of history , clinical examination , special tests and radiological examination , and not as the outcome of any one specific test. With the advent of technologies in our day to day life we need the help of technologies in dentistry also. An effort has been made to provide readers with contemporary , evidence based prospective on endodontic diagnosis. Vitality testing is an important aid in the diagnosis of pulp disease and apical periodontitis. The ideal pulp test method should provide a simple , objective , standardized , reproducible , nonpainful , noninjurious , accurate and inexpensive way of assessing the condition of the pulp tissue. This article describes the various t echnologies that are available to aid the dental practitioner in detecting a tooth with a relevant endodontic disease. It also explains the need and limitation of the technologies as an aid in our management of endodontically affected tooth.

Full Text Available Chronic diarrhea is a common problem in patients with acquired immune deficiency syndrome (AIDS, resulting in significant morbidity and potential mortality. In the early stages of immunodeficiency, human immunodeficiency virus (HIV-infected patients are susceptible to infection with the same enteric pathogens that cause diarrhea in immunocompetent hosts, but with progressive immunodeficiency, these patients become susceptible to numerous opportunistic disorders. The main factor to consider when tailoring the work-up of diarrhea in the HIV-infected patient is the immune status, which is reflected by the total CD4 lymphocyte cell count. A CD4 count of less than 100 cells/µL is significantly correlated with opportunistic disorders. For the HIV-infected patient with diarrhea, repeated stool studies to investigate for bacteria, ova and parasites should be the first step. When either upper or lower gastrointestinal tract symptoms are present and stool studies are negative, endoscopy directed to the probable organ of involvement is appropriate. If localizing symptoms are absent, the most appropriate next test is sigmoidoscopy with biopsies. Not infrequently, despite extensive evaluation, the cause of diarrhea in patients with AIDS remains unexplained. Recently, the widespread use of highly active antiretroviral therapy, including protease inhibitors, has led to a change in the epidemiology of diarrhea in AIDS patients. As their immune status improves, HIV-infected patients treated with combination therapy become less prone to opportunistic disorders. However, diarrhea appears to be frequent because several antiretroviral agents can themselves cause diarrhea.

The notion that foreign aid harms the institutions of recipient governments remains prevalent. We combine new disaggregated aid data and various metrics of political institutions to re-examine this relationship. Long-run cross-section and alternative dynamic panel estimators show a small positive...... net effect of total aid on political institutions. Distinguishing between types of aid according to their frequency domain and stated objectives, we find this aggregate net effect is driven primarily by the positive contribution of more stable inflows of ‘governance aid’. We conclude the data do...... not support the view that aid has had a systematic negative effect on political institutions....

Despite anecdotal evidence that the quality of governance in recipient countries affects the allocation of international health aid, there is no quantitative evidence on the magnitude of this effect, or on which dimensions of governance influence donor decisions. We measure health-aid flows over 1995-2006 for 109 aid recipients, matching aid data with measures of different dimensions of governance and a range of country-specific economic and health characteristics. Everything else being equal, countries with more political rights receive significantly more aid, but so do countries with higher corruption levels. The dependence of aid on political rights, even when we control for other governance indicators, suggests that health aid is sometimes used as an incentive to reward political reforms.

Aid may raise the marginal productivity of capital by financing complementary inputs, such as public infrastructure projects and human capital investment. However, aid may also crowd out productive private investments if it comes...... The notion that foreign aid and foreign direct investment (FDI) are complementary sources of capital is conventional among governments and international cooperation agencies. This paper argues that the notion is incomplete. Within the framework of an open economy Solow model we show...... in the shape of physical capital transfers. We therefore turn to an empirical analysis of the relationship between FDI and disaggregated aid flows.

Full Text Available A self-contained, self-fitting hearing aid (SFHA is a device that enables the user to perform both threshold measurements leading to a prescribed hearing aid setting and fine-tuning, without the need for audiological support or access to other equipment. The SFHA has been proposed as a potential solution to address unmet hearing health care in developing countries and remote locations in the developed world and is considered a means to lower cost and increase uptake of hearing aids in developed countries. This article reviews the status of the SFHA and the evidence for its feasibility and challenges and predicts where it is heading. Devices that can be considered partly or fully self-fitting without audiological support were identified in the direct-to-consumer market. None of these devices are considered self-contained as they require access to other hardware such as a proprietary interface, computer, smartphone, or tablet for manipulation. While there is evidence that self-administered fitting processes can provide valid and reliable results, their success relies on user-friendly device designs and interfaces and easy-to-interpret instructions. Until these issues have been sufficiently addressed, optional assistance with the self-fitting process and on-going use of SFHAs is recommended. Affordability and a sustainable delivery system remain additional challenges for the SFHA in developing countries. Future predictions include a growth in self-fitting products, with most future SFHAs consisting of earpieces that connect wirelessly with a smartphone and providers offering assistance through a telehealth infrastructure, and the integration of SFHAs into the traditional hearing health-care model.

More than 20 years ago, even before voters in Oregon had enacted the first aid in dying (AID) statute in the United States, Timothy Quill and colleagues proposed clinical criteria AID. Their proposal was carefully considered and temperate, but there were little data on the practice of AID at the time. (With AID, a physician writes a prescription for life-ending medication for a terminally ill, mentally capacitated adult.) With the passage of time, a substantial body of data on AID has developed from the states of Oregon and Washington. For more than 17 years, physicians in Oregon have been authorized to provide a prescription for AID. Accordingly, we have updated the clinical criteria of Quill, et al., based on the many years of experience with AID. With more jurisdictions authorizing AID, it is critical that physicians can turn to reliable clinical criteria. As with any medical practice, AID must be provided in a safe and effective manner. Physicians need to know (1) how to respond to a patient's inquiry about AID, (2) how to assess patient decision making capacity, and (3) how to address a range of other issues that may arise. To ensure that physicians have the guidance they need, Compassion & Choices convened the Physician Aid-in-Dying Clinical Criteria Committee, in July 2012, to create clinical criteria for physicians who are willing to provide AID to patients who request it. The committee includes experts in medicine, law, bioethics, hospice, nursing, social work, and pharmacy. Using an iterative consensus process, the Committee drafted the criteria over a one-year period.

As the number of HIV infected patients is multiplying exponentially day by day so are the associated ocular complications.The increasing longevity of individuals with HIV disease has resulted in greater numbers of pa-tients with ocular opportunistic infection.By the means of this article we describe various opportunistic ocular infections in AIDS and their clinical manifestations,discussed under four headings;1 )adnexal manifestation;2)anterior segment manifestation;3)posterior segment manifestation;4)neuro ophthalmic manifestation . Herpes zoster ophthalmicus,molluscum contagiosum and Kaposi sarcoma are common adnexal manifestations. Molluscum contagiosum being the commonest.Varicella Zoster Virus (VZV)and herpes simplex virus (HSV) most commonly cause infectious keratitis in HIV-positive patients .As compared to the immunocompetent indi-viduals the frequency of bacterial and fungal keratitis is not more in HIV patients,but it tends to be more se-vere.Posterior segment structures involved in HIV-positive patients include the retina,choroid,and optic nerve head.The herpesvirus family is implicated most commonly in infections of the retina and choroid in HIV positive patients.CMV is the most common cause of retinitis and the commonest intraocular infection in AIDS. Atypical presentations resistance to conventional treatment and higher rate of recurrence make the diagnosis and therapeutic intervention more difficult and challenging.In addition,in one eye,several infections may occur at the same time,rendering the situation more difficult.

This report presents a 15-year climatological study of severe weather events and related severe weather atmospheric parameters. Data sources included local forecast rules, archived sounding data, Cloud-to-Ground Lightning Surveillance System (CGLSS) data, surface and upper air maps, and two severe weather event databases covering east-central Florida. The local forecast rules were used to set threat assessment thresholds for stability parameters that were derived from the sounding data. The severe weather events databases were used to identify days with reported severe weather and the CGLSS data was used to differentiate between lightning and non-lightning days. These data sets provided the foundation for analyzing the stability parameters and synoptic patterns that were used to develop an objective tool to aid in forecasting severe weather events. The period of record for the analysis was May - September, 1989 - 2003. The results indicate that there are certain synoptic patterns more prevalent on days with severe weather and some of the stability parameters are better predictors of severe weather days based on locally tuned threat values. The results also revealed the stability parameters that did not display any skill related to severe weather days. An interactive web-based Severe Weather Decision Aid was developed to assist the duty forecaster by providing a level of objective guidance based on the analysis of the stability parameters, CGLSS data, and synoptic-scale dynamics. The tool will be tested and evaluated during the 2005 warm season.
In the 1998 food crisis in Rumbek county, South Sudan, Dinka mothers began voluntarily to remove their malnourished children from Oxfam's therapeutic feeding programs. This article explains how the incident has led Oxfam to re-examine its ideas about food aid in the region and to take a fresh look at Dinka ideas of need. It was shown that Dinka ideas of vulnerability do not always coincide with the norm when it comes to food aid distribution. Dinka life revolves around the cattle, which provide milk for the children and the elderly. Thus, they believed that a child whose family or clan has sufficient cattle should not need special attention, even if they happen to be thin occasionally. In view of this, Oxfam decided that the best way forward was to discuss these issues and set up a workshop of women and men involving food decision making. In the workshop, Oxfam explained the purposes and outcomes of giving food to the malnourished, or the ¿weak¿ as the Dinka termed it and this became a negotiation over feeding attendance. It was finally agreed that the chiefs would allow ¿weak¿ children to receive double rations, on the condition that Oxfam discuss the issues with the World Food Programme.

Designing modern hearing aids is a formidable challenge. The size of hearing aids is constantly decreasing, making them virtually invisible today. Still, as in all other modern electronics, more and more features are added to these devices driven by the development in modern IC technology....... The demands for performance and features at very low supply voltage and power consumption constantly prove a challenge to the physical design of hearing aids and not at least the design of the ICs for these. As a result of this all large hearing aid manufacturers use fully customized ASICs in their products....... The size of the amplifier is critical for the size of the final hearing aid and a study of the size of these for different manufactures will be presented. Designing the ICs for hearing aids poses many challenges and is a constant compromise between size, power consumption and performance of the individual...

Chinese development assistance is totally different in nature in comparison with the aid offered by the United States and Japan. The U.S. sees its aid as a form of "mercy" to less-developed countries and gives it with numerous conditions attached. Japan seems to mainly use it to pursue commercial interests. By contrast, Chinese aid is, in essence, cooperation and mutual support between developing countries. This fundamental difference helps to explain why Beijing's aid is so different from that of the Western donors.
This article considers the epidemic proportion of AIDS in developing countries, and discusses the U.S. Agency for International Development's (USAID) reworked and intensified strategy for HIV infection and AIDS prevention and control over the next 5 years. Developing and launching over 650 HIV and AIDS activities in 74 developing countries since 1986, USAID is the world's largest supporter of anti-AIDS programs. Over $91 million in bilateral assistance for HIV and AIDS prevention and control have been committed. USAID has also been the largest supporter of the World Health Organization's Global Program on AIDS since 1986. Interventions have included training peer educators, working to change the norms of sex behavior, and condom promotion. Recognizing that the developing world will increasingly account for an ever larger share of the world's HIV-infected population, USAID announced an intensified program of estimated investment increasing to approximately $400 million over a 5-year period. Strategy include funding for long-term, intensive interventions in 10-15 priority countries, emphasizing the treatment of other sexually transmitted diseases which facilitate the spread of HIV, making AIDS-related policy dialogue an explicit component of the Agency's AIDS program, and augmenting funding to community-based programs aimed at reducing high-risk sexual behaviors. The effect of AIDS upon child survival, adult mortality, urban populations, and socioeconomic development in developing countries is discussed. Program examples are also presented.

The present paper examines the macroeconomic impact of aid, by introducing endogenous aid allocations into a neoclassical growth framework. On this basis it is shown that donor policies can have important implications for the trajectory of recipients' GDP per capita. Depending on specific donor...... policy choices, aid disbursements may lead to faster transitional growth, stagnation or cyclical growth. Moreover, the analysis also suggests that donor policies may be part of the reason why foreign aid is not found to be uniformly effective in raising long-run productivity across recipients...

The AIDS dilemma continues to escalate, leaving a legacy that probably will affect the nation for years to come. The U.S. Centers for Disease Control, the National Academy of Sciences, and the U.S. Surgeon General have noted that in the absence of a vaccine or treatment for AIDS, education remains the only effective means to prevent the spread of the disease. Thus, schools have an important role in protecting the public health. To respond appropriately to the situation, school personnel must become familiar with relevant information and resources available concerning AIDS. This article first provides essential information about AIDS using a question-and-answer format. Second, policy statements addressing school attendance by students infected with the virus that causes AIDS are presented. Third, hotlines that can be used to obtain more detailed information about AIDS are described. Fourth, organizations that can provide information for school health education about AIDS are identified. Fifth, an annotated list of audiovisual materials that schools can use to provide education about AIDS is provided. Sixth, a bibliography of publications relevant to school health education about AIDS is offered.

Although most clinical tests focus on how much a particular hearing aid improves speech audibility under controlled conditions, it is unclear how these measures relate to hearing aid effectiveness, or the benefit perceived by the patient under everyday conditions. In this study, the relationship between audibility and hearing aid effectiveness was examined in a cohort of patients who obtained hearing aids through the Veteran's Administration. The measure of audibility was the Articulation Index, a common index of speech audibility. Measures of effectiveness included two hearing-specific surveys and self-reported ratings of global satisfaction and hearing aid use adherence. Results indicated that there were no systematic relationships between measurements of improved audibility and patient ratings of communication ability. Additionally, improved audibility was not related to overall satisfaction with the amplification characteristics of the hearing aid (fitting). However, improved audibility is related to hearing aid use adherence, with patients who achieve better audibility reporting that they use their hearing aids more frequently.
Navistar International Transportation Corporation, Chicago, IL, used three separate NASA-developed technologies in the design and testing of their 3000 Series Bus Chassis which was developed expressly for school bus applications. For structural analysis, they used the MSC/NASTRAN program which mathematically analyzes a design and predicts how it will hold up under stress. They also used the SPATE 9000 system for non-contact measurement of stress, load transfer mechanisms, detection of hidden flaws, and monitoring structural changes during fatigue testing. SPATE 9000 was based on infrared stress measurement technology developed by Langley Research Center. They also employed the Wyle Ride Quality Meter, which was developed by Langley to aid in passenger aircraft design by providing an accurate measurement of ride vibration and sound level. These numbers translate into a subjective discomfort level index. These technologies contribute to the company's 45-48 percent share of the school bus chassis market.

Full Text Available Food aid is a critical component of the global food system, particularly when emergency situations arise. For the first time, we evaluate the water footprint of food aid. To do this, we draw on food aid data from theWorld Food Programme and virtual water content estimates from WaterStat. We find that the total water footprint of food aid was 10 km3 in 2005, which represents approximately 0.5% of the water footprint of food trade and 2.0% of the water footprint of land grabbing (i.e., water appropriation associated with large agricultural land deals. The United States is by far the largest food aid donor and contributes 82% of the water footprint of food aid. The countries that receive the most water embodied in aid are Ethiopia, Sudan, North Korea, Bangladesh and Afghanistan. Notably, we find that there is significant overlap between countries that receive food aid and those that have their land grabbed. Multivariate regression results indicate that donor water footprints are driven by political and environmental variables, whereas recipient water footprints are driven by land grabbing and food indicators.

Hearing aids are one of the most widely used treatment options for the hearing impaired and optimal outcomes of hearing aids are supported by comprehensive hearing aid fitting protocols. Currently, the term 'hearing aid fitting' is prevalently used among service and industry sectors with its comprehensive procedures not systematically explicated. In addition, a variety of non-normalized guidelines for hearing aid fitting has led to non-uniform care, outcome variability, and dissatisfaction of the use of hearing aids. The main purpose of the present study is to suggest a general framework of standardized practice for hearing aid fitting management including its pre- and post-fitting stages. The management framework centers on its fitting process with its prior steps of assessment as well as its posterior steps of follow-up, thereby eliminating diverging interpretations and non-uniform practices. Outcomes of this study are also expected to improve potential benefits such as quality of hearing aid fitting, user satisfaction, and cost effectiveness across relevant stakeholders.

The importance of leadership, especially human rights-driven leadership, in the fight against HIV/AIDS is widely recognized. However, argues Michael Pates in this commentary, the type of bold leadership required to really make a difference has been lacking. Pates calls for the development of an AIDS Leadership Initiative and describes how it might happen.

Due to the large amount of options offered by the vast number of adjustable parameters in modern digital hearing aids, it is becoming increasingly daunting—even for a fine-tuning professional—to perform parameter fine tuning to satisfactorily meet the preference of the hearing aid user. In addition......, the communication between the fine-tuning professional and the hearing aid user might muddle the task. In the present paper, an interactive system is proposed to ease and speed up fine tuning of hearing aids to suit the preference of the individual user. The system simultaneously makes the user conscious of his own...... preferences while the system itself learns the user’s preference. Since the learning is based on probabilistic modeling concepts, the system handles inconsistent user feedback efficiently. Experiments with hearing impaired subjects show that the system quickly discovers individual preferred hearing-aid...
Full Text Available Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward.

In-the-ear, in-the-canal and behind-the-ear hearing aids were compared for ease of management by elderly people. Two hundred and forty-four clients were randomly assigned to be fitted with one aid type, and rated for ability to perform the manipulative tasks necessary to enable effective use of the aid. It was found that in-the-ear aids were easiest to use, that females experienced greater difficulties in manipulation than males and that some tasks were easier to perform and more quickly learned than others. The findings are discussed in terms of design requirements and aid fitting practices.
Full Text Available HIV entered and began to spread throughout India approximately one decade later than it did in the US, Canada, Europe, other developed countries, Africa, and the Caribbean. Accordingly, the AIDS epidemic in India continues to evolve, with the spread of HIV infection in many parts of India already reaching epidemic proportions. The long incubation period between HIV infection and the onset of AIDS, however, means that the majority of infected adults will come down with AIDS in the mid-1990s. AIDS in India will have significant adverse economic effects upon the country. Once ill with opportunistic infections as a result of HIV infection, people will require treatment. The costs of such treatment will strain resources. High levels of AIDS morbidity and mortality among individuals in their most productive years will also reduce the overall productive contributions of society to economic development. The extent of the HIV/AIDS problem in India needs to be accurately assessed, then followed by the implementation of appropriate prevention and care programs. The situation will not be able to reversed if responsible parties act only after the existence of HIV/AIDS becomes evident in large numbers of people. Policymakers and program planners working against the spread of HIV throughout India will be called upon to strike and maintain a balance in the allocation of resources for treatment and prevention. They will have to be realistic, yet humanistic, while considering individual rights in the context of more broad social welfare. The authors explain that it is cheaper to prevent AIDS than to treat and manage it, and that urgent measures are needed to protect the productive base of the economy. Sections discuss the role of epidemiology, the spread of HIV through infected needles and syringes, AIDS and HIV in Maharashtra, and the economics of AIDS.

Full Text Available In the Indonesia Demographic Health Survey 1994 ever married women age 15-49 years were asked whether they have ever heard of AIDS and if so their sources of information concerning prevention and treatment of the disease, and their personal perception about the risk of getting the disease. Half of the women age 20-34 years have ever heard about AIDS and among the older women less than half of them have ever heard about it. This analysis describes information about the relationship between knowledge of ever married women 15-49 years about AIDS with various background characteristics - age, education, occupation, exposure to mass media, area, and regions. This information is required to improve the existing health education campaign about AIDS. The results indicate that women with less than secondary education or married to husband with less than secondary education or women who do not work or working as farmers are less likely to have ever heard about AIDS. Women who are not exposed to any type of mass media or exposed to only one media are less likely to have ever heard about AIDS than those who are exposed to two or more media. The proportion of women who have ever heard about AIDS in outer Java Bali region is lower than in Java Bali region, likewise in the rural areas it is lower than in urban areas. There are significant associations between area, region, women' education, husbands' education, occupation, exposure to mass media and having ever heart about AIDS. The major source of information about AIDS are from TV and second are newspapers and radio. To control the transmission of HIV/ AIDS the role of mass media is very important and therefore it is necessary to improve the coverage and acceptability of the information considering mothers' education, region/area, and occupation. The information material should be simple and easily understood by the various social levels of community.

The scientific debate between pros and cons of the HIV criminal theory of AIDS still remains unsettled. The purpose of this review is to promote resolution of the problem by extracting a common principle of the host-virus relation using data resources for each of 4 viruses as follows: a) polyoma virus, b) Marek's disease virus, c) Ebola virus, d) Korean hemorrhagic fever virus. Conclusions drawn from this study are given as follows: i) Environment emerged as the cardinal factor to modify the process of virus infection in all of the 4 viruses studied. Above all, an accelerating effect of environmental stress on the progression of virus infection was noted in vivo in the majority of viral diseases. ii) Evidence is available to indicate that a healthy cell (or a healthy individual) may harbor virus genes of multiple species without manifesting any pathologic sign. iii) Evidence also suggests that the biological property as well as morphological structure of a virus may vary in reponse to a change of the bioenvironment. On the basis of the above information, we propose to renounce 2 assumptions of classical infection model: a) the hereditarily determined virulence of a microorganism (including virus) be the sole determinant of infection to the effect that its invasion into the host should automatically complete the programmed course of infection; b) virus, a quasi-living creature, should reserve its behavioral independence irrespective of a change of the bioenvironment. The new infection model was constructed on the basis of the selfish gene concept that had been invented by Richard Dawkins to explain the altruistic behavior of an individual. That is, the fate of an exogenous or endogenous virus is under the dual control of the host genome (selfish gene) and the outer environment. The progression of virus infection is conditioned by a crosstalk between them. The selfish gene may use virus (a lifeless substance) as a magic bullet to induce a designated host response. In
Advocates for many developing-world health and population issues have expressed concern that the high level of donor attention to HIV/AIDS is displacing funding for their own concerns. Even organizations dedicated to HIV/AIDS prevention and treatment have raised this issue. However, the issue of donor displacement has not been evaluated empirically. This paper attempts to do so by considering donor funding for four historically prominent health agendas--HIV/AIDS, population, health sector development and infectious disease control--over the years 1992 to 2005. The paper employs funding data from the Organization for Economic Cooperation and Development's (OECD) Development Assistance Committee, supplemented by data from other sources. Several trends indicate possible displacement effects, including HIV/AIDS' rapidly growing share of total health aid, a concurrent global stagnation in population aid, the priority HIV/AIDS control receives in US funding, and HIV/AIDS aid levels in several sub-Saharan African states that approximate or exceed the entirety of their national health budgets. On the other hand, aggregate donor funding for health and population quadrupled between 1992 and 2005, allowing for funding growth for some health issues even as HIV/AIDS acquired an increasingly prominent place in donor health agendas. Overall, the evidence indicates that displacement is likely occurring, but that aggregate increases in global health aid may have mitigated some of the crowding-out effects.
A multi-national lab collaborative team was assembled that includes experts from academia and industry to enhance recently developed Computer-Aided Battery Engineering for Electric Drive Vehicles (CAEBAT)-II battery crush modeling tools and to develop microstructure models for electrode design - both computationally efficient. Task 1. The new Multi-Scale Multi-Domain model framework (GH-MSMD) provides 100x to 1,000x computation speed-up in battery electrochemical/thermal simulation while retaining modularity of particles and electrode-, cell-, and pack-level domains. The increased speed enables direct use of the full model in parameter identification. Task 2. Mechanical-electrochemical-thermal (MECT) models for mechanical abuse simulation were simultaneously coupled, enabling simultaneous modeling of electrochemical reactions during the short circuit, when necessary. The interactions between mechanical failure and battery cell performance were studied, and the flexibility of the model for various batteries structures and loading conditions was improved. Model validation is ongoing to compare with test data from Sandia National Laboratories. The ABDT tool was established in ANSYS. Task 3. Microstructural modeling was conducted to enhance next-generation electrode designs. This 3- year project will validate models for a variety of electrodes, complementing Advanced Battery Research programs. Prototype tools have been developed for electrochemical simulation and geometric reconstruction.

A technique has been developed for combining features of a systems architecture design and assessment tool and a software development tool. This technique reduces simulation development time and expands simulation detail. The Architecture Design and Assessment System (ADAS), developed at the Research Triangle Institute, is a set of computer-assisted engineering tools for the design and analysis of computer systems. The ADAS system is based on directed graph concepts and supports the synthesis and analysis of software algorithms mapped to candidate hardware implementations. Greater simulation detail is provided by the ADAS functional simulator. With the functional simulator, programs written in either Ada or C can be used to provide a detailed description of graph nodes. A Computer-Aided Software Engineering tool developed at the Charles Stark Draper Laboratory (CSDL CASE) automatically generates Ada or C code from engineering block diagram specifications designed with an interactive graphical interface. A technique to use the tools together has been developed, which further automates the design process.

Activation-induced cytidine deaminase (AID) is expressed in a B cell differentiation stage-specific fashion and is essential for immunoglobulin (Ig) gene class switch DNA recombination (CSR) and somatic hypermutation (SHM). CSR and SHM play a central role in the maturation of antibody and autoantibody responses. AID displays a mutagenic activity by catalyzing targeted deamination of deoxycytidine (dC) residues in DNA resulting in dU:dG mismatches, which are processed into point-mutations in SHM or double-strand breaks (DSBs) in CSR. Although AID specifically targets the Ig gene loci (IgH, Igκ and Igλ), it can also home into a wide array of non-Ig genes in B-and non-B-cell backgrounds. Aberrant expression of AID is associated with multiple diseases such as allergy, inflammation, autoimmunity and cancer. In autoimmune systemic lupus erythematosus, dysregulated AID expression underpins increased CSR, SHM and autoantibody production. As a potent mutator, AID is under stringent transcriptional, post-transcriptional and post-translational regulation. AID is also regulated in its targeting and enzymatic function. In resting naïve or memory B cells, AID transcripts and protein are undetectable. These, however, are readily and significantly up-regulated in B cells induced to undergo CSR and/or SHM. Transcription factors, such as HoxC4 and NF-κB, which are up-regulated in a B cell lineage-and/or differentiation stage-specific manner, regulate the induction of AID. HoxC4 induces AID expression by directly binding to the AID gene promoter through an evolutionarily conserved 5'-ATTT-3' motif. HoxC4 is induced by the same stimuli that induce AID and CSR. It is further up-regulated by estrogen through three estrogen responsive elements in its promoter region. The targeting of AID to switch (S) regions is mediated by 14-3-3 adaptor proteins, which specifically bind to 5'-AGCT-3' repeats that are exist at high frequency in S region cores. Like HoxC4, 14-3-3 adaptors are induced

The Women and AIDS Research Program (International Center for Research on Women) has identified a series of obstacles to preventing HIV infection among women, including social norms that mandate female ignorance about sexual matters, women's economic dependence on men, widespread acceptance of male promiscuity, and violence against women. Most AIDS prevention programs fail to challenge these contextual determinants and continue to focus on the promotion of condom use among men. Recommendations to empower women and improve their status are dismissed as long-term measures outside the domain of AIDS prevention. Feasible, however, is the modification of existing AIDS prevention programs to ensure they are gender-sensitive. This would mean measures such as providing services at times that are convenient to women and integrating services to reduce waiting and travelling times. To address the contextual issues at the root of women's vulnerability to HIV, AIDS prevention programs can link up with economic interventions such as credit programs, agricultural extension services, and women's cooperatives. Moreover, AIDS programs can provide HIV-infected women with social support through group educational sessions or counseling. Finally, because improvements in women's socioeconomic status are essential for the success of all AIDS prevention, program managers should be in the forefront of broader struggles to enact policy changes to eliminate gender-based discrimination and inequality.

Reported are the results of a multicentre study involving 40 laboratories that was carried out in France to assess all the currently available methods used for the serodiagnosis of toxoplasmosis. For this purpose 10 batches of control sera were prepared with titres in the range 0-260 IU per ml. These sera were tested in nine laboratories using immunofluorescence methods; in three laboratories using dye tests; in forty laboratories using enzyme-linked immunosorbent assay; in four laboratories using direct agglutination and haemagglutination; in seven laboratories using the high-sensitivity IgG agglutination test; and in three laboratories using the latex agglutination test. In this way, 70 series of titrations were carried out using seven procedures and the results were compared with those obtained using the WHO reference serum in 15 cases, with the French national E6 serum in 16 other cases, and in 39 cases using 15 reference sera supplied by the reagent manufacturers. Rigorous comparison of the tests was not possible in all cases because one aim of the study was to ensure that the tests were carried out under the usual working conditions that prevailed in the participating laboratories. The results obtained indicate that the serological tests currently available for toxoplasmosis are acceptable for its serodiagnosis. Presentation of the titres in IU has advantages; however, caution is required since the definition of IU varies according to the test and reagents used. It is therefore essential that the conditions and limits for a positive reaction be carefully defined in each case, especially for commercially available kits.

Hatred and fear of homosexuals, together with a fear of losing tourism revenue, drove many high-level policymakers in the Caribbean to ignore the HIV/AIDS in its infancy. With an annual incidence rate of at least 146.6 people per 100,000, the Bahamas now has one of the highest AIDS rates in the world and the highest such rate in the English-speaking Caribbean. AIDS has become the major cause of death for men and women aged 20-44 in the Bahamas. Indeed, throughout the Caribbean, countries like the Bahamas must now cope with a growing AIDS epidemic. UN AIDS Program figures indicate that at least 310,000 people in the Caribbean have either HIV infection or AIDS, and that the prevalence rate among adults is almost 2%. This compares with an estimated 7.4% of the adult population of sub-Saharan Africa which is infected and 0.6% of adults in North America. 65% of reported AIDS cases in the region result from heterosexual intercourse. While the annual number of AIDS cases has been falling in North America over the last several years and rates in Latin America have leveled off, rates in the Caribbean are increasing sharply. Poverty, the population's lack of awareness, low levels of education, internal and international migration, crack cocaine use, promiscuity, high levels of STDs, prostitution, and tourism are also facilitating the spread of HIV in the Caribbean. Social conservatism, mainly in the English-Caribbean, about discussing sex impedes the implementation and success of HIV/AIDS prevention interventions.
A seminar of the International Labor Organization (ILO) was held to shed light on the role of AIDS in decimating qualified professionals in Anglophone Africa. The estimates of the World Health Organization indicate that the number of people infected with HIV in the whole world was 13-15 million persons at the end of 1994, of which 8 million lived in sub-Saharan Africa. In Uganda it is calculated that 1.5 million people are carriers of HIV, and by 1998 this figure could increase to 1.9 million. In both Zambia and Zimbabwe, in the 20-39 year age group, AIDS cases amount to 70% and 74%, respectively. Studies carried out in Rwanda, Zaire, Swaziland, and Zimbabwe revealed that AIDS is most frequent among members of the higher socioeconomic classes. The inability to find replacements for jobs requiring higher qualifications will result in dire consequences for these economies. During the 6-year period between 1988-89 and 1993-94 the Uganda Commercial Bank registered 229 deaths due to AIDS among its 1600 employees (14%). AIDS also requires the expenditure of scarce health resources on treatment: in 1992, hospital occupancy for diseases associated with AIDS reached 40-60% in Kinshasa, Zaire; 50% in Lusaka, Zambia; 60% in Kigali, Rwanda; and 70% in Bujumbura, Burundi. Various programs have been launched to fight HIV/AIDS in Zimbabwe, Zambia, and Uganda, to sensitize and educate people about the epidemic. The protection of human rights, the avoidance of discrimination, and the adoption of safe sex techniques are promoted by these programs. Companies have programs to combat AIDS. Ubombo Ranches Ltd. in Swaziland started an information program in 1991 and distributed free condoms. BAT Uganda Ltd. also started an information and training-of-trainers program in 1989, which by 1994 had benefitted about 90% of the employees. This has resulted in the reduction of AIDS cases and associated medical costs.

Full Text Available Explore new concept of self-aid and buddy-aid for combat wounded based on the emergency timeliness and the challenges we are going to face in the future combats, the importance of self-aid, buddy-aid and rescue are discussed. The concept and characteristics of self-aid and buddy-aid in our army are reviewed, and the care of the wounded in foreign armies were reviewed. Based on the experiences gained from previous combats, and the results of "Medical Service Mission-2014 Drill", it was believed that the emergency rescue of battle wounded should follow the timeliness rule and the principle of self-aid and buddy-aid technology. It might be beneficial to use cell protective agent, urgent relief of life-threatening conditions such as profuse bleeding from extremities, suffocation, pneumothorax, and traumatic shock etc., in order to stabilize the general condition of the wounded, according to the regime of "Platinum 10 minutes" and "golden 1 hour", self-aid and buddy-aid might play an important role in preventing early death and late morbidity of the wounded, thus helps reduce the mortality rate or the victims of combat wounds.

This compendium is the result of an effort to compile, organize, and rapidly publish as much relevant molecular data concerning the human immunodeficiency viruses (HIV) and related retroviruses as possible. The scope of the compendium and database is best summarized by the four parts that it comprises: (1) Nucleic Acid Alignments, (2) Amino Acid Alignments, (3) Reviews and Analyses, and (4) Related Sequences. Information within all the parts is updated throughout the year on the Web site, http://hiv-web.lanl.gov. This year we are not including floppy diskettes as the entire compendium is available both at our Web site and at our ftp site. If you need floppy diskettes please contact either Bette Korber (firstname.lastname@example.org) or Kersti Rock (email@example.com) by email or fax ((505) 665-4453). While this publication could take the form of a review or sequence monograph, it is not so conceived. Instead, the literature from which the database is derived has simply been summarized and some elementary computational analyses have been performed upon the data. Interpretation and commentary have been avoided insofar as possible so that the reader can form his or her own judgments concerning the complex information. The exception to this are reviews submitted by experts in areas deemed of particular and basic importance to research involving AIDS viral sequence information. These are included in Part III, and are contributed by scientists with particular expertise in the area of interest. In addition to the general descriptions below of the parts of the compendium, the user should read the individual introductions for each part.

This article is a systhematic literature review including the period from 1994 to 2009, whose objective was to discuss the aged woman's vulnerability in relation to Acquired Imunodeficiency Syndrome (Aids). The search for scientific texts was accomplished in the following databases: Biblioteca Virtual em Saúde, Scientific Eletronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE). The descriptors used were vulnerability, woman and Aids. Eighteen texts were analyzed, including articles in scientific journals, thesis and dissertations. As a conclusion, it was noted that aged women and vulnerability to Aids are directly related, through gender characteristics including submission and that were built historical and socially. We consider as fundamental the development of studies which may generate publications accessible to women, in order to help them see themselves as persons vulnerable to Aids contagion just for being women.

Relying on his tour of 16 sub-Saharan countries, the author judges the extent of acquired immunodeficiency syndrome (AIDS) in Africa on a scale from grade I (not much of a problem) to grade V (a catastrophe). In his assessment, AIDS is a problem (grade II) in only 5, possibly 6, countries where it has occurred. In no country is the AIDS problem consistently grade III (a great problem), nor ever grade IV (an extremely great problem), and in none can it be called a catastrophe (grade V). In Kenya, for instance, contrary to widespread rumors, the author rates AIDS in 1987 as grade I. Journalistic hyperbole has proved very expensive in that Africans overseas have experienced racial abuse and tourism has unjustly suffered. Tension seems to have developed between white doctors working in Africa, with externally funded research in danger of being halted in several countries.

The first case of AIDS was registered in Thailand in 1984; this syndrome was deemed to be mainly a disease affecting homosexuals and foreigners. However, soon thereafter its incidence among prostitutes and intravenous drug users increased. According to 1995 data, the number of AIDS patients was about 20,000 and there were approximately 800,000 HIV-positive people. A 1991 map of the AIDS incidence showed that, after the Bangkok metropolitan area, the province of Chiang Mai in the north exhibited a particularly high rate of infection. According to a medium-range forecast, by the year 2010 there will be close to 2.3 million cumulative HIV infection cases and 1.2 million AIDS cases in Thailand. This corresponds to an infection rate of about 3.2% vs. the present 2%. It is estimated that about 20% of all mortality in the age range of 20-48 years in the year 2000 will be caused by AIDS. In 1995, the prime minister predicted that AIDS would cause a 20% drop of the GDP by 2000. The boom of the economy in the 1980s and the early 1990s led to migration to the cities, where prostitution and drug use are rampant, as well as to the emergence of sex tourism, mainly from Germany (40,000-60,000 Germans traveled to Thailand in 1990). The age-old tradition among married men of seeking out the services of prostitutes, lack of condom use (only 20% of men intend to use it, according to recent studies), and disregard for the AIDS problem among the populace are other factors contributing to the rapid spread of AIDS. UNAIDS has undertaken sex education and other information campaigns to counter the epidemic.

In this paper we present a novel concept in which special band aid is developed for early detection of cancer. The band aid contains an array of micro needles with small detection array connected to each needle which inspects the color of the surface of the skin versus time after being pinched with the needles. We were able to show in pre-clinical trials that the color varies differently if the skin is close to tumor tissue.
The author explains why pictures have such impact. Images catch people's attention and to some extent can substitute for written words. They can be either still images like posters and flipcharts, three-dimensional images such as models or puppets, or they can show live events through drama, film, and video. Each of these are considered visual aids when used as teaching tools. When choosing visual aids, it is important to know which audience is being addressed and why, and to choose the visual aid which is most appropriate for the occasion. It is very important to pre-test pictures, especially when they will be used on their own without a facilitator to help participants analyze them. While some visual aids, such as maps and diagrams, are understood by everyone, people in some remote areas where there are very few books or papers may find pictures hard to understand. Facilitators are crucial to the successful use of visual aids. It is therefore very important that facilitators receive quality training. Well-trained facilitators from the local area will be more aware of local culture and concerns, and may be more trusted by participants. Poor training must be avoided. Finally, even though pictures can be misinterpreted, visual aids can make teaching and learning more enjoyable for many people. For people who find reading or speaking out difficult, the use of pictures may be the only way they can participate in discussions and decisions.

Advances in microsensors, microprocessors, and microdisplays are creating new opportunities for improving vision in degraded environments through the use of head-mounted displays. Initially, the cutting-edge technology used in these new displays will be expensive. Inevitably, the cost of providing the additional sensor and processing required to support binocularity brings the value of binocularity into question. Several assessments comparing binocular, binocular, and monocular head-mounted displays for aided vision have concluded that the additional performance, if any, provided by binocular head-mounted displays does not justify the cost. The selection of a biocular [corrected] display for use in the F-35 is a current example of this recurring decision process. It is possible that the human binocularity advantage does not carry over to the aided vision application, but more likely the experimental approaches used in the past have been too coarse to measure its subtle but important benefits. Evaluating the value of binocularity in aided vision applications requires an understanding of the characteristics of both human vision and head-mounted displays. With this understanding, the value of binocularity in aided vision can be estimated and experimental evidence can be collected to confirm or reject the presumed binocular advantage, enabling improved decisions in aided vision system design. This paper describes four computational approaches-geometry of stereopsis, modulation transfer function area for stereopsis, probability summation, and binocular summation-that may be useful in quantifying the advantage of binocularity in aided vision.
Ricewater has been proved to be an effective treatment of diarrhea by investigators at the International Center for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), who have shown that cereal-based solutions are even more effective than the much publicized mixtures of water, sugar, and salts. Diarrhea kills 8 or 9 children under the age of 5 every minute, often simply by draining out of them the water and salts the body needs to keep functioning. Only a few years ago, the conventional treatment for severe cases was a drip of saline fluid into the patients arm through a needle. But this requires hospital treatment, and few 3rd world children ever see the inside of a hospital. Recently, "oral rehydration therapy" (ORT)--giving children a carefully measured mix of water, sugar (or pure glucose), and sodium chloride and potassium salts--has gained world recognition as a simple, cheap, and effective treatment. A village mother can give it in her home, either from a prepackaged powder mixed with water or from solution she mixes herself. Sugar, or the glucose into which the body converts sugar, continues to be absorbed across the intestinal walls during diarrhea--when the body is absorbing little else. This process aids the absorption of the all-important salts. The standard ORT formula for a liter of water calls for 20 g of glucose or 40 g of household sugar. The newer cereal-based ORT replaces the sugar with rice powder. Tests have shown that 80-86% of the rice powder is converted into glucose and absorbed. According to Dr. A. Majid Molloa of ICDDR,B who pioneered the use of rice powder in ORT, 1 liter of rice powder solution is twice as effective as 2 liters of sugar solution. There are several advantages in using rice powder in ORT. Rice is the staple food of more than 1/2 the world's population, particularly so where diarrhea is a killer. It is grown and eaten throughout Asia, and in many parts of Latin America and Africa. Some rice is usually available in the
Full Text Available AID (Activation Induced Deaminase deaminates cytosines in DNA to initiate immunoglobulin gene diversification and to reprogram CpG methylation in early development. AID is potentially highly mutagenic, and it causes genomic instability evident as translocations in B cell malignancies. Here we show that AID is cell cycle regulated. By high content screening microscopy, we demonstrate that AID undergoes nuclear degradation more slowly in G1 phase than in S or G2-M phase, and that mutations that affect regulatory phosphorylation or catalytic activity can alter AID stability and abundance. We directly test the role of cell cycle regulation by fusing AID to tags that destabilize nuclear protein outside of G1 or S-G2/M phases. We show that enforced nuclear localization of AID in G1 phase accelerates somatic hypermutation and class switch recombination, and is well-tolerated; while nuclear AID compromises viability in S-G2/M phase cells. We identify AID derivatives that accelerate somatic hypermutation with minimal impact on viability, which will be useful tools for engineering genes and proteins by iterative mutagenesis and selection. Our results further suggest that use of cell cycle tags to regulate nuclear stability may be generally applicable to studying DNA repair and to engineering the genome.

OBJECTIVE: To study epidemiology and possible risk factors associated with the development of cryptosporidiosis among European patients with AIDS. METHODS: An inception cohort of 6548 patients with AIDS, consecutively diagnosed from 1979 to 1989, from 52 centres in 17 European countries was studied. Data on all AIDS defining events were collected retrospectively from patients' clinical records. Kaplan-Meier estimates, log rank tests and Cox proportional hazard models were used to examine for possible risk factors associated with cryptosporidiosis. RESULTS: Cryptosporidiosis was diagnosed in 432 (6.6%) patients, 216 at time of the AIDS diagnosis and 216 during follow-up. The probability of being diagnosed with cryptosporidiosis at AIDS diagnosis was significantly lower for intravenous drug users (1.3%) than for homosexual men (4.1%) and for patients belonging to other transmission categories (4.0%) (p < 0.001). The probability was also higher for patients from Central Europe compared with patients from South Europe (4.1% versus 2.5%, p = 0.005). The rate of developing cryptosporidiosis after the diagnosis of AIDS was 3 per 100 patient years of follow-up. The rate was significantly lower for intravenous drug users than for homosexual men (relative risk 0.34, 95% confidence limits 0.22-0.54) and for women compared with men (RR 0.43 (0.21-0.87)). The risk was higher in North Europe than in South and Central Europe. In a multivariate analysis only transmission category remained a significant predictor for the development of cryptosporidiosis. CONCLUSION: The development of cryptosporidiosis in AIDS patients may be associated with sexual risk behaviour. PMID:8698361

Background Effective risk communication is essential for informed decision making. Unfortunately, many people struggle to understand typical risk communications because they lack essential decision-making skills. Objective The aim of this study was to review the literature on the effect of numeracy on risk literacy, decision making, and health outcomes, and to evaluate the benefits of visual aids in risk communication. Method We present a conceptual framework describing the influence of numeracy on risk literacy, decision making, and health outcomes, followed by a systematic review of the benefits of visual aids in risk communication for people with different levels of numeracy and graph literacy. The systematic review covers scientific research published between January 1995 and April 2016, drawn from the following databases: Web of Science, PubMed, PsycINFO, ERIC, Medline, and Google Scholar. Inclusion criteria were investigation of the effect of numeracy and/or graph literacy, and investigation of the effect of visual aids or comparison of their effect with that of numerical information. Thirty-six publications met the criteria, providing data on 27,885 diverse participants from 60 countries. Results Transparent visual aids robustly improved risk understanding in diverse individuals by encouraging thorough deliberation, enhancing cognitive self-assessment, and reducing conceptual biases in memory. Improvements in risk understanding consistently produced beneficial changes in attitudes, behavioral intentions, trust, and healthy behaviors. Visual aids were found to be particularly beneficial for vulnerable and less skilled individuals. Conclusion Well-designed visual aids tend to be highly effective tools for improving informed decision making among diverse decision makers. We identify five categories of practical, evidence-based guidelines for heuristic evaluation and design of effective visual aids.

The authors describe the projected impact of AIDS on mortality, explain the reasons for the differences in mortality projections by major international organizations, and offer an approach to estimating the impact of AIDS upon life expectancy. Although AIDS has already significantly increased mortality in many countries, the impact of AIDS upon mortality is expected to grow substantially over the next 10 years and into future decades. By 2005, the population of the most severely affected countries in Africa will be 13-59 million less than it would have been without AIDS, and life expectancy may decline by as much as 27% in those countries. Uncertainty about current and future trends in HIV prevalence among adults has led to differences in the projections of future AIDS-related mortality. For example, while the UN projects that AIDS will reduce the population growth of the most severely affected countries in Africa by 13 million by 2005 and 30 million by 2025, the US Census Bureau projects the reduction to be 59 million by 2005 and 120 million by 2025. These differences are largely due to the use of different methodologies for projecting future levels of adult HIV prevalence. There are also differing estimates of current levels of HIV prevalence and differing assumptions about the length of the incubation period and the perinatal transmission rate. As data and projection methodologies improve, the differences in projections may be reduced for sub-Saharan Africa, while the growing epidemic in some of the largest countries of Asia may increase uncertainty about future global impacts.
Having a multitude of different ethnic communities forces Canada's AIDS educators to use many different methods to deliver their messages. These range from an AIDS bingo game that has been used to educate natives in northern Manitoba to attempts to take AIDS education to the streets of Toronto. With AIDS education, reports Olga Lechky, one message definitely does not fit all.

Employing sector-specific aid data, we find that the five largest donors react to aid giving by other donors with whom they compete in terms of exporting goods...... and services to a specific recipient country at both stages of their allocation of aid for economic infrastructure and production sectors. By contrast, evidence for export competition driving aid allocation is lacking for more altruistic donors and for aid in social infrastructure. © 2014 Elsevier Ltd....

In the absence of a drug or vaccine to curtail the acquired immunodeficiency syndrome (AIDS) epidemic, health education offers the most productive approach. The majority of National AIDS Committees have established AIDS education programs aimed at reducing the high-risk behaviors associated with AIDS. The content of an AIDS educational program varies according to the educational level and cultural norms of the target audience, but is crucial to determining whether misconceptions and prejudices about the disease will be reinforced or dispelled. It is suggested that all AIDS-related materials should be examined in relation to the following factors: accuracy (correct statistics and factually true statements); current (the presentation of present trends and developments); appropriate to objectives (suitable for the purpose); appropriate to the level of the target audience (in terms of not only literacy level, but also emotional maturity and special sensitivities); adequate (sufficient information as to be useful); and objective and unbiased. Each subject covered in AIDS prevention materials--the natural history of the epidemic, the nature of infection with AIDS, signs and symptoms, modes of transmission, and preventive strategies--should be analyzed in relation to the above factors.

Introduction The impact of auditory sensory deprivation in the life of an individual is enormous because it not only affects one's ability to properly understand auditory information, but also the way people relate to their environment and their culture. The monitoring of adult and elderly subjects with hearing loss is intended to minimize the difficulties and handicaps that occur as a consequence of this pathology. Objective To evaluate the level of user satisfaction with hearing aids. Methods A clinical and experimental study involving 91 elderly hearing aid users. We used the questionnaire Satisfaction with Amplification in Daily Life to determine the degree of the satisfaction provided by hearing aids. We evaluated mean global score, subscales, as well as the variables time to use, age, and degree of hearing loss. Results Mean global score was 4.73, the score for Positive Effects 5.45, Negative Factors 3.2, demonstrating that they were satisfied; Services and Costs 5.98: very satisfied ; 3.65 Personal Image: dissatisfied. We observed statistically significant difference for the time of hearing aid use, age, and degree of hearing loss. Conclusion The SADL is a tool, simple and easy to apply and in this study we can demonstrate the high degree of satisfaction with the hearing aids by the majority of the sample collected, increasing with time of use and a greater degree of hearing loss.

The Joint UN Program on AIDS reports that India has more than 3 million adults infected with HIV, more HIV-infected adults than any other country in the world. By the year 2005, India will have more people infected with HIV than does Africa. Having sex with a Bombay housewife today is at least twice as risky as it was to have sex with a prostitute in the city's red light district in 1988. 2-3% of all women in the city are infected with HIV. There is ignorance, apathy, corruption, and lack of commitment at all levels with regard to HIV/AIDS. Accordingly, India's lackluster campaign against AIDS launched 10 years ago has lost momentum just as the epidemic is exploding and at a time when traditional beliefs about cultural barriers and the sexual behavior of Indian males are being called into question. Considerable homosexual behavior occurs in India. However, the most important factor contributing to the spread of HIV throughout India is the virus' spread from urban areas into small villages, often through migrant laborers. Ignorance, illiteracy, and poverty in villages will make AIDS prevention especially difficult. Indian government policy forbidding the distribution of condoms in prisons, needles to injectable-drug users, and free drugs to AIDS patients further contributes to the spread of HIV.

The working memory plays an important role in successfully overcoming adverse listening conditions and should consequently be considered when designing and testing hearing aids. A number of studies have established the relationship between hearing in noise and working memory involvement, but with the Sentence-final Word Identification and Recall (SWIRL) test, it is possible to show that working memory is also involved in listening under favorable conditions and that noise reduction has a positive influence in situation with very little noise. Although the capacity of the working memory is a finite individual size, its involvement can differ with fatigue and other factors and individualization of hearing aids should take this into account to obtain the best performance. A way of individually adapting hearing aids is based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids. Such an adaptation could be done based on changes in the electrical activity of the brain (EEG). Here we present the possibilities that arise from using EEG and show that ear-mounted electrodes is able to record useful EEG that can be explored for individualization of hearing aids.

The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

This study clarified that automation bias is something unique to automated decision making contexts, and is not the result of a general tendency toward complacency. By comparing performance on exactly the same events on the same tasks with and without an automated decision aid, we were able to determine that at least the omission error part of automation bias is due to the unique context created by having an automated decision aid, and is not a phenomena that would occur even if people were not in an automated context. However, this study also revealed that having an automated decision aid did lead to modestly improved performance across all non-error events. Participants in the non- automated condition responded with 83.68% accuracy, whereas participants in the automated condition responded with 88.67% accuracy, across all events. Automated decision aids clearly led to better overall performance when they were accurate. People performed almost exactly at the level of reliability as the automation (which across events was 88% reliable). However, also clear, is that the presence of less than 100% accurate automated decision aids creates a context in which new kinds of errors in decision making can occur. Participants in the non-automated condition responded with 97% accuracy on the six "error" events, whereas participants in the automated condition had only a 65% accuracy rate when confronted with those same six events. In short, the presence of an AMA can lead to vigilance decrements that can lead to errors in decision making.

This has led to designs where the receiver (loudspeaker) and microphones are placed closely together. As a consequence, problems...... with vibroacoustic transmission from the receiver to the microphones often occur during the use of hearing aids. This transmission causes feedback at certain critical gain levels where it produces a loud uncomfortable squealing. Consequently feedback often constitutes the limiting factor for the maximum obtainable...... gain in the hearing aid and it therefore represents a critical design problem. Feedback in hearing aids is usually divided into external and internal feedback. External feedback is caused by the leakage of sound from the ear canal whereas internal feedback is due to transmission of sound and vibrations...
Urgent action is needed to fight the alarming spread of HIV/AIDS that infected 1.3 million people in Southeast Asia last year alone, Malaysia's foreign minister said July 24, 2000. Syed Hamid said the Association of Southeast Asian Nations (ASEAN) should tackle at regional and national level an epidemic that was taking its most drastic toll among the region's youth. "HIV/AIDS not only represents a major public health and social problem but is a serious challenge to development as well," Syed Hamid told the opening ceremony of ASEAN's 33rd annual foreign ministers' meeting. The crisis requires commitment at the "highest political level," he said, warning that HIV/AIDS could become a transnational problem within the 10-member group. Foreign ministers have recommended their leaders discuss the crisis later this year at an informal summit in Singapore and hold a summit on HIV/AIDS in conjunction with the 7th ASEAN Summit in Brunei next year. "I think people recognized the importance and the adverse impacts on our social development," Syed Hamid told reporters later. "I think it is a real issue that we cannot run away from." Among ASEAN members, Thailand, Cambodia, and Myanmar have some of the highest infection rates in Asia of HIV, the virus that causes AIDS.

Several recent papers find evidence that global health aid is being diverted to reserves, education, military, or other sectors, and is displacing government spending. This is suggested to occur because ministers of finance have competing, possibly corrupt, priorities and deprive the health sector of resources. Studies have found that development assistance for health routed to governments has a negative impact on health spending and that similar assistance routed to private nongovernmental organizations has a positive impact. An alternative hypothesis is that World Bank and IMF macro-economic policies, which specifically advise governments to divert aid to reserves to cope with aid volatility and keep government spending low, could be causing the displacement of health aid. This article evaluates whether aid displacement was greater when countries undertook a new borrowing program from the IMF between 1996 and 2006. As found in existing studies, for each $1 of development assistance for health, about $0.37 is added to the health system. However, evaluating IMF-borrowing versus non-IMF-borrowing countries reveals that non-borrowers add about $0.45 whereas borrowers add less than $0.01 to the health system. On average, health system spending grew at about half the speed when countries were exposed to the IMF than when they were not. It is important to take account of the political economy of global health finance when interpreting data on financial flows.
Pressures to create a profitable Third World market for Western drugs may have led to the suppression of acquired immunodeficiency syndrome (AIDS) treatments developed in Africa. Six years before four Western pharmaceutical companies announced the discovery of a three-drug regimen that appears to produce remission in some patients infected with human immunodeficiency virus (HIV), Ugandan physician Dr. Charles Ssali had developed a similar formulation. Beginning in 1989, Dr. Ssali gave HIV-infected patients at his Kampala clinic a preparation, Miriandina, containing 27 naturally occurring anti-oxidants and micronutrients that stimulate the immune system and prevent progression to AIDS. To date, he has treated over 12,000 patients, with an 80% success rate. His first patient, who presented in 1989 with full-blown AIDS, is alive and symptom-free. Miriandina is taken for 12-18 months, at a cost of only US $0.50 per tablet ($600 for six months of treatment). Another herbal formulation, Pearl Omega, developed by scientist Arthur Obel with funds provided by the Kenyan government, has produced a similar reversal of AIDS symptoms. However, international donor organizations and the AIDS establishment have refused to fund these African-based efforts or to publicize their success. It is suggested that this reflects a plan to force African countries to take out World Bank loans to finance the more expensive ($8300 a course) Western-based protease inhibitors.

Full Text Available OBJECTIVE: To determine the extent to which the narrowing of child mortality across wealth gradients has been related to foreign aid to the health sector in low- and middle-income countries. METHODS: Mortality and wealth data on 989,901 under-5 children from 957,674 households in 49 aid recipient countries in Africa, Asia, South America, and the Caribbean between 1993 and 2012 were used in the analysis. Declines in under-5 mortality in the four poorest wealth quantiles were compared to the decline among the wealthiest at varying levels of health aid per capita using fixed effects multivariable regression models and controlling for maternal education, urbanization, and domestic spending on health among recipient countries. RESULTS: Each additional dollar in total health aid per capita was associated with 5.7 fewer deaths per 10,000 child-years among children in the poorest relative to the wealthiest households (p<0.001. This was also true when measured in percent declines (1.90% faster decline in under-5 mortality among the poorest compared with the wealthiest with each dollar in total health aid, p = 0.008. The association was stronger when using health aid specifically for malaria than total health aid, 12.60% faster decline among the poorest compared with the wealthiest with each dollar in malaria aid, p = 0.001. CONCLUSIONS: Foreign aid to the health sector is preferentially related to reductions in under-5 mortality among the poorest compared with the wealthiest. Health aid addressing malaria, which imposes a disproportionate burden among the poor, may explain the observed effect.

HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

This study explores shared thinking about HIV/AIDS among Zambian adolescents. With high numbers affected, the question is how this group represents its risk. Social representations of the origin, spread and risk of HIV/AIDS were gleaned via 60 semistructured interviews with urban 15 to 20 year olds. A systematic analysis revealed a shared picture: AIDS was linked to the West, God and teenage girls; its spread lay beyond the control of adolescent boys and men; and the personal sense of vulnerability was low. The results are discussed in light of their corroboration of the finding that social representations of danger can be identity protective, yet also system justifying. The potential transfer of such findings to psychological theory and to health campaigns is considered.

Over the last few decades, computer-aided drug design has emerged as a powerful technique playing a crucial role in the development of new drug molecules. Structure-based drug design and ligand-based drug design are two methods commonly used in computer-aided drug design. In this article, we discuss the theory behind both methods, as well as their successful applications and limitations. To accomplish this, we reviewed structure based and ligand based virtual screening processes. Molecular dynamics simulation, which has become one of the most influential tool for prediction of the conformation of small molecules and changes in their conformation within the biological target, has also been taken into account. Finally, we discuss the principles and concepts of molecular docking, pharmacophores and other methods used in computer-aided drug design.
SINCE the first case of AIDS was reported in the early 1980s the number of HIV patients has been increasing. According to the estimate of the World Health Organization, the number of HIV carriers has risen to 19.5 million, among whom 4:5 million have developed AIDS, resulting in 1 million AIDS-related deaths. By the year 2000, the number of HIV carriers worldwide is predicted to reach 40 million. By the time the global 40 million mark is reached, 90 percent of these cases are predicted to be in developing countries. Then the number of HIV carriers in Asia will likely surpass the number in Africa. China, comprising one-fifth of the world’s population, with underdeveloped

This report describes the NASA Lexical Dictionary, a machine aided indexing system used online at the National Aeronautics and Space Administration's Center for Aerospace Information (CASI). This system is comprised of a text processor that is based on the computational, non-syntactic analysis of input text, and an extensive 'knowledge base' that serves to recognize and translate text-extracted concepts. The structure and function of the various NLD system components are described in detail. Methods used for the development of the knowledge base are discussed. Particular attention is given to a statistically-based text analysis program that provides the knowledge base developer with a list of concept-specific phrases extracted from large textual corpora. Production and quality benefits resulting from the integration of machine aided indexing at CASI are discussed along with a number of secondary applications of NLD-derived systems including on-line spell checking and machine aided lexicography.

Laws can only partially succeed in modifying behavior, especially with regard to sex, drug use, and other human pleasures. Effective and just laws to slow the spread of AIDS must therefore be based upon a thorough knowledge of the issues, not upon ignorance, fear, political expediency, or to meet the emotional demands of an often ignorant general population. Good laws, like good ethics, are founded in good data. The most effective response to the AIDS epidemic is neither prohibition nor punishment of individual behavior, but laws designed to truly affect human behavior and shape a society in which the spread of HIV is minimized. Central to an appropriate legislative response is the imperative of protecting the basic rights of individuals infected with HIV. An example of an enlightened, rational, and nondiscriminatory approach to checking the spread of HIV/AIDS while guaranteeing individual freedoms and rights is found in a report commissioned for the State Government of New South Wales. The following measures are recommended to bring state laws into harmony with the national HIV/AIDS strategy: decriminalize brothels, set regulations and public health standards for sex workers, cover sex workers under the Industrial Relations Act, ensure the privacy of HIV/AIDS patients and improve their redress against discrimination in the workplace, repeal laws which make it illegal to possess and administer drugs to oneself, investigate the therapeutic use of marijuana as a prescribed treatment for HIV/AIDS and other terminal illnesses, abandon compulsory testing for HIV in prisons, make condoms available to prisoners and sexually active children, establish a Natural Death Act to allow terminally ill patients to die with dignity, and give legal status to permanent relationships between homosexual couples.
Policy and program planners use information gained from computer-based statistical models to develop interventions against AIDS. Models of the epidemic's effect, however, show widely differing impacts on population. With the recent entry of a British researcher's view of the impact of AIDS on the population of Africa, the debate between researchers has only intensified. While the World Health Organization (WHO) has conservatively estimated that 40 million people will be infected with HIV by the year 2000, Roy Anderson of the University of London and Robert May of Oxford University expect AIDS to cause population decline in Africa after the year 2002. Major donors and researchers feel that while population growth rates will decline, growth rates will not turn negative due to AIDS. The British researchers, however, do not consider their views to differ greatly from those of US researchers, but they do have problems with overly conservative WHO projections. Their research assumes a higher degree of transmission between core groups of HIV-positive people, including prostitutes, IV drug users, and general populations in Africa's hardest hit areas. They project infection prevalence to reach 50% or more in some areas. Greater levels of prostitution and poverty, as well as the tendency for males to have sex with increasingly younger females, will lead to higher HIV incidence and prevalence in Africa. Family planning experts are voicing their concern over the integrity of these models and question whether they are more than simply educated guesses of what the future holds. Even though projections are uncertain and extremely data-dependent, family planning efforts must continue. Whether or not the AIDS pandemic eventually levels off in certain areas, critics must remember that family planning improves maternal and child health in addition to contributing to lower growth rates and prevent AIDS.
Full Text Available AIM: to clinically analyze 50 cases of low vision patients attending tertiary care hospital, their acceptance of low visual aids and to identify common ocular conditions leading to low vision. METHODS: A two year prospective study was done and fifty patients with low vision who attended the low vision clinic were examined for low visual aids acceptance and improvement of acuity, fields or ability to carry out daily activities. Patients underwent clinical low vision examination and they were assessed for low visual aids prescription and the kind of low visual prescribed for distance and near tasks. RESULTS: The age distribution showed maximum number of patients were in the age group of 51 - 60 years with male preponderance of 72 %. The most common disease causing low vision were retinitis pigmentosa followed my macular dystrophy, diabetic retinopathy and age related macular degeneration. Other diseases were POAG, myopic macular degeneration, optic atrophy and nystagmus. Spectacle magnifiers were most commonly prescribed in 44% for distant vision followed by telescopes in 38% of patients for near vision. Field expanders were prescribed for patients with advances glaucoma and retinitis pigmentosa. Other near vision aids included hand magnifiers, stand magnifiers and CCTV. Both the distant telescopes and magnifiers for near vision improved the visual acuity by three lines which improved further on increasing the illumination. In patients with extensive scotomas of near fixation point, hand and stand magnifiers were better than spectacle magnifier. CONCLUSI ON: The study shows that low visual aids can be prescribed in various ocular diseases depending upon occupation, age and needs of the patient. Low visual aids help patients to make use of remaining vision to maximum extent so that they utilize residual vision effectively to meet their daily requirement

The acquired immunodeficiency syndrome (AIDS) is an infectious disease caused by the human immunodeficiency virus (HIV). It was first recognized in the United States in 1981, and the HIV/AIDS epidemic has since spread to affect all countries. The interface of HIV/AIDS with opportunistic infectious diseases is well characterized, but further research is required into the concurrence of other chronic diseases. The objective of this review was to identify possible interferences of HIV infection in the diagnosis and management of rheumatoid arthritis (RA). A review of the available evidence was conducted using the GRADE approach. Overall, the quality of evidence was low. Our main conclusions were: (1) the occurrence of rheumatoid-like arthritis in patients with HIV/AIDS is quite rare; therefore, it is not recommended that HIV infection be considered routinely as a differential diagnosis in this condition (C2); (2) HIV infection may lead to rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody positivity, but usually at low titers (C1); (3) RA might cause false-positive HIV serology and ELISA seems to be a more specific test for HIV in patients with RA (C2); (4) RA and AIDS may coexist, even in cases of severe immunosuppression (C1); (5) RA emergence may seldom occur during or after immune reconstitution (C1); and (6) there is insufficient safety data to recommend use of specific disease-modifying antirheumatic drugs (DMARDs) in RA patients with HIV/AIDS. Therefore, these drugs should be used cautiously (C1).

The 18 research articles of this volume discuss the major themes that have emerged from mathematical and statistical research in the epidemiology of HIV. The opening paper reviews important recent contributions. Five sections follow: Statistical Methodology and Forecasting, Infectivity and the HIV, Heterogeneity and HIV Transmission Dynamics, Social Dynamics and AIDS, and The Immune System and The HIV. In each, leading experts in AIDS epidemiology present the recent results. Some address the role of variable infectivity, heterogeneous mixing, and long periods of infectiousness in the dynamics of HIV; others concentrate on parameter estimation and short-term forecasting. The last section looks at the interaction between the HIV and the immune system.

Indexing with computers is a far cry from indexing with the first indexing tool, the manual card sorter. With the aid of computer-aided lexicography, both indexing and indexing tools can provide standardization, consistency, and accuracy, resulting in greater quality control than ever before. A brief survey of computer activity in indexing is presented with detailed illustrations from NASA activity. Applications from techniques mentioned, such as Retrospective Indexing (RI), can be made to many indexing systems. In addition to improving the quality of indexing with computers, the improved efficiency with which certain tasks can be done is demonstrated.

Using two ethnographic case studies, the intersecting dynamics of inequality, morality, and corruption are examined as they play out in Nigerian AIDS NGOs. To the Nigerian public, local AIDS organizations are widely seen as conduits for corruption. But local opinions of particular NGOs and their leaders turn less on whether donor resources were misused and more on the ways that people who accumulate the benefits of corruption use them socially. Nevertheless, discontent swirls about corruption in general, a fact that suggests a gradual change in people's understandings of the processes that produce inequality in Nigeria.

Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to
Superbarrio is the name given to the folk hero and spokesperson of the Asamblea de Barrios--a democratic assembly of Mexico City's poorer neighborhoods. Dressed like Batman, he is often the central figure in mass demonstrations for better living conditions. Now he is appearing with Superwoman in the Assembly's campaign against AIDS. In February 1990, Superbarrio spoke at the opening of a community AIDS information center, set up and run by women members of the Assembly. A brigade of volunteer educators handed out leaflets and condoms in the surrounding streets and underground stations.

The Hispanic AIDS Committee for Education and Resources (HACER) was established in 1987 as an AIDS education program targeted at the Mexicano population of South Texas. The word "Mexicano" is used because "Hispanic" refers to a larger, more diversified group. "Mexicano" refers specifically to people of South Texas who are either Mexican-Americans (people of Mexican descent, born and educated in the US) or Mexicans (people born and educated in Mexico). Mexicanos constitute 56% of the population of South Texas and 54% of the population of San Antonio. Mexican-Americans, in general, speak and read English and listen to English-language television and radio. Mexicans are poorer and less educated, Spanish-speaking, and often illiterate. The Mexicanos do not constitute a high risk group for AIDS; at present there are only 64 Mexicano AIDS patients in San Antonio. AIDS education campaigns on television which are directed at the whole Hispanic community may be counter-productive when directed at the Mexicano population because they know that AIDS is not yet a serious problem among them, and scare tactics only cause hysteria. AIDS education is essential, but it must be specifically geared to the Mexicano community, which, in general, is a very conservative community, in which subjects like sex, homosexuality, condoms, or anal intercourse are not discussed in public. But it is also a community of young (median age 23) sexually active people. An AIDS education program directed at them must use simple, elementary language in standard Mexican Spanish for the Mexicans and in English for the young Mexican-Americans. The single most effective way to reach the Mexicano population would be public service announcements aired on television during the time when the telenovelas (soap operas) are on. Not only are the telenovelas widely watched, but their actors are popular heros, who will be listened to by their audience. The use of radio for public service announcements would be useful

Given the relevance of AIDS as a public health problem in the Italian context and of the role of mass media in the social construction of the phenomenon, the aim of the present study is twofold: (1) to explore the main AIDS-related themes in the Italian popular press; (2) to analyse the temporal trends of AIDS representations over the last decades. For the research, we decided to consult Italian newspaper articles produced between 1985 and 1990 and between 2005 and 2010 using the archives of the main two national newspapers (La Repubblica and Corriere della Sera), resulting in an overall sample of 446 newspaper articles. A computer-aided content analysis allowed the detection of five different thematic domains (clusters), respectively focused on: Medical care (7.47%), Family support (37.03%), Science and religion debate (27%), Social exclusion (17.6%) and Healthcare policies (10.9%). These thematic domains are conceived along two main latent dimensions (factors) which explain 72.47% of the data variance which respectively deal with: (1) Attitudes towards people with AIDS (care versus avoidance) and (2) Social mandate on AIDS (powerlessness versus control). The study results also reveal the potential evolution of representations of people with AIDS over time: from stigmatised subjects who represent a risk for the entire society within a climate of social control to people progressively symbolised as frail subjects that need to be taken care of.

Background The prevalence of HIV/AIDS in Chinese ethnic minorities is an important component of China's AIDS issues. In this study, we launched an intervention programme in Yunnan Province of China, where the Dai people live, to carry out the community-based HIV/AIDS health education and behavioral interventions on ordinary Dai farmers. The Dai people believe in Theravada Buddhism.Methods Four rural communities were randomly divided into two groups. In one group (Buddhist group), HIV/AIDS health education and behavioral intervention were carried out by monks. The other group (women group) was instructed by women volunteers. The intervention continued for one year and the data were collected before and after the intervention project.Results In the Buddhist group, the villagers' AIDS related knowledge score was boosted from 3.11 to 3.65 (P<0.001),and some indices of the villagers' behavior using condoms improved after the intervention. But this improvement was poorer than that in the women group. In the Buddhist group, the villager's attitude score towards the people living with HIV and AIDS (PLWHA) also increased significantly from 1.51 to 2.16 (P<0.001).Conclusion The results suggested that the Buddhist organization has limited success in promoting the use of condoms,but plays an important role in eliminating HIV/AIDS related discrimination.

This paper opens by expressing disappointment in the disparities between published estimations of the effectiveness of foreign aid to developing countries and effectiveness data which arise from the application of complex econometric methods. The new dilemmas for aid policy include the fact that aid increasingly devoted to human development at the expense of productive activity is unlikely to create the material development which will allow maintenance of human development targets. The second part of the paper presents comparative statistics on gross national product, official development assistance, and savings growth which paint a disturbing picture because the growth of domestic savings has been negative in the period 1967-87 in nine of the 11 less developed countries with data available. Section 3 covers the shortcomings of econometric experiments which neither confirm nor deny the findings of other studies on the effectiveness of aid. The fourth section describes constraints to the growth of income imposed by the foreign exchange, the rate of return on investment, and the growth of labor productivity and presents statistical evidence supporting aid policy which would 1) take advantage of opportunities to rehabilitate output growth in traditional industries without the addition of a great deal of capital, 2) direct attention to increasing the absolute gross national product (GNP) to raise the growth of per capital income, and 3) strategically reorient the structure of aid to increase the absolute GNP faster to accelerate reversal of the negative savings pattern and speed the reduction of fertility. Section 5 considers suggested shifts in aid policy orientation dealing with 1) population growth, income level, and food security; 2) reconstruction and structural adjustment; 3) rationalizing aid for social, institutional, and human development and technical assistance. The concluding section notes that the suggested strategic reorientation of the structure of aid

Loss of mobility in the elderly causes a significant economic burden to caregivers and is one of the most significant determinants of depression and loss of muscle strength and productivity in this age group. Mobility aids can assist with locomotion by providing physical support, however they fail to provide direction guidance and avoidance of obstacles and hazards. This talk will focus on design of intelligent adaptive wheeled walkers. By allowing the user varying degrees of control, from complete to collaborative, these walkers afford the user with the feeling of control, while helping to increase the ease and safety of their daily travels. The control systems of these walkers differ from those of other mobility aids and mobile robots because they must both assist in mobility and provide balance and support, but also give directional aid if necessary. These functions must be performed in a tight loop adaptation with a human whose input may be difficult to predict. Through the use of a wheeled walker equipped with force and sonar sensors, we were able to develop an intelligent self-guided mobility aid that can provide improved independence, autonomy, and quality of life for the elderly.

Especially the placement of the so-called faceplate on the hearing aid strongly influences the size and shape of the hearing aid. Since...... the future hearing aid production will be less manual there is a need for algorithms that mimic the craftsmanship of skilled operators. In this paper it is described how a statistical shape model of the ear canal can be used to predict the placement of the faceplate on a hearing aid made for a given ear...
In March 1994, the National AIDS Prevention and Control Programme in Pakistan launched its media campaign. Staffers have had to work within Islamic principles to inform the public about the risk of HIV infection and to encourage the public to adopt behavior to prevent its transmission. The media messages are not sexually explicit. They call for Pakistanis to call a hotline for or to ask medical professionals about more detailed information on AIDS. The hotline number is memorable (123). The 2 hotlines in Islamabad receive 250-300 calls/day. These hotlines deliver a recorded message with information on the significance of condoms in AIDS prevention and allows callers an opportunity to leave a telephone number or address if they want information. Staff advise callers who are concerned that they may be infected with HIV to obtain a test at 1 of 30 sites and to attend the National Institute for Health in Islamabad for more testing and counseling if the first test is positive. The hotline system will soon expand to all other major Pakistani cities. The program receives 300-400 letters/week asking for specific information. The program had workshops for journalists as its first wave of increasing AIDS awareness. The journalists followed with thoughtful articles on AIDS. Program staff spent much energy to obtain support from Islamic leaders. More media professionals have joined efforts to disseminate information through various media forums to encourage people to seek treatment for sexually transmitted diseases. The program's goal is a 55% increase in the number of people who can name at least 2 correct ways to prevent HIV transmission and an increase in condom use from 1% to 70%. The program eventually would like to increase outreach efforts by working with nongovernmental organizations and by developing videos and short stories.

Full Text Available Objectives: To describe information about HIV/AIDS in a youth population under 18 years of age affected with HIV/AIDS and caregivers in five Colombian cities: Cali, Buenaventura, Barranquilla, Santa Marta, and Cartagena.Methods: 286 personal surveys were conducted: 11 of children who were aware of their status of involvement with HIV/AIDS and 275 of caregivers of children who did not know their status of involvement with HIV/AIDS. The surveys were conducted in health institutions in the State and private sectors and private, using instruments in line with training programs from participating institutions to inquire about HIV/AIDS. Descriptive analysis was performed of the data and tabulation was done with the SPSS program.Results: Most children who knew their status of involvement with HIV/AIDS report that by acquiring the HIV virus, they may develop other diseases; however, half of these fail to recognize that AIDS weakens the body’s ability to fight infection. The children surveyed partly recognized the HIV/AIDS transmission and treatment mechanisms, while caregivers possess adequate information on the disease. We found reasons to delay the delivery of diagnosis by caregivers 96.2% (N=275 related to avoiding psychological harm to the children, and that if they were to know said status, they might inadvertently disclose this to others, probably exposing them to stigma and/or discrimination. Likewise, professionals providing health services to HIV seropositive children express lack of training regarding the proper procedure and age to reveal such information.Conclusions: It is a priority to enhance the capacity, information, and education of patients about effects, characteristics, manifestations, and treatment of the disease within the comprehensive health management processes conducive to supporting affected families.

Full Text Available This study evaluated differences in AIDS patients with and without tuberculosis (TB in Espírito Santo State, Brazil. Standard regional AIDS (SINAN, SISCEL, SICLOM and SIM and tuberculosis (SINAN databases were used. TB and AIDS databases were linked using Reclink software, version 3, with SPSS software support to identify co-infected cases. Data from July 2000 to June 2006 in Espírito Santo State were linked. The results showed 3,523 adult AIDS cases and 9,958 adult TB cases resulted in 430 co-infected patients, who were compared to 1,290 AIDS patients who never developed TB. Among 430 co-infected patients, TB was diagnosed first in 223 (51.9%, AIDS was first in 44 (10.2%, and AIDS and TB were diagnosed concurrently in 163 (37.9%. Median age did not differ between co-infected cases (36 years (interquartile range [IQR] 29-43 and non-co-infected cases (34 years; IQR 28-42. Pulmonary tuberculosis was diagnosed in 239 (55.6%; 109 (25.3% had extra-pulmonary TB and 82 (19.1% had both presentations.

Objective To evaluate the level of user satisfaction with hearing aids. Methods This is a cross-sectional group study comprising 108 subjects (56% men and 44% women. The average age of the subjects was 77 years. These subjects had been recently fitted with their hearing aids and showed sensorineural (90% and mixed (10% hearing loss as determined via the Questionnaire International Outcome Inventory for Hearing Aids Outcome Inventory (IOI-HA, which determined the benefit and satisfaction obtained by sound amplification. Results The hearing aids improved the quality of life of 52.78% of the patients, which was revealed by their high scores (mean = 27.3. The relationship of the user with the environment was significantly better (p < 0.001 than that of the user with the hearing aid. Conclusion IOI-HA is a simple and easy-to-use tool. Based on the results of this study, we can show a high degree of satisfaction with their hearing aids in the majority of the participants, which improved the quality of life.
Full Text Available Conventionally, heterogeneous object modeling methods paid limited attention to the concurrent modeling of geometry design and material composition distribution. Procedural method was normally employed to generate the geometry first and then determine the heterogeneous material distribution, which ignores the mutual influence. Additionally, limited capability has been established about irregular material composition distribution modeling with strong local discontinuities. This article overcomes these limitations by developing the computer-aided design–computer-aided engineering associative feature-based heterogeneous object modeling method. Level set functions are applied to model the geometry within computer-aided design module, which enables complex geometry modeling. Finite element mesh is applied to store the local material compositions within computer-aided engineering module, which allows any local discontinuities. Then, the associative feature concept builds the correspondence relationship between these modules. Additionally, the level set geometry and material optimization method are developed to concurrently generate the geometry and material information which fills the contents of the computer-aided design–computer-aided engineering associative feature model. Micro-geometry is investigated as well, instead of only the local material composition. A few cases are studied to prove the effectiveness of this new heterogeneous object modeling method.
By the end of 2005, the estimated number of HIV infected people in China was 650,000. The seriousness of the epidemic calls for effective control measures to tackle the problems in order to avoid the tragedy in Africa from happening in China. "Prevention First" is the cornerstone of the country's health policy. On 2003 World AIDS Day, Premier Jiabao Wen announced a new national AIDS control policy, "Four Frees and One Care". This policy clearly shows that the Chinese government has once again taken full responsibility to solve public health problems and has profound impact far beyond the AIDS field. In early 2006, the central government put scientific and technology innovation as a national priority and set the target to build an innovative China by year 2020. Since then, the government has been increasing investment in science and technology with major emphasis on both infectious diseases control and new drug research and development. For the first time, development of 100 new drugs and control of major infectious diseases (AIDS, HBV, TB and other emerging infectious diseases) have been selected as national key scientific projects. China's best minds in related fields will be pooled to work together in order to remove the technical barriers blocking efficient control of the major infectious disease in China. Knowledge on molecular epidemiology, immunology, pathogenesis, HAART, as well as HIVDR strains will certainly provide urgently needed scientific information for China's AIDS control program. Only evidence-based strategy from good research will provide long-term effective control of AIDS.

Serological diagnosis of Zika virus (ZIKV) infections is challenging due to high cross-reactivity between flaviviruses. We evaluated the diagnostic performance of a novel anti-ZIKV ELISA based on recombinant ZIKV non-structural protein 1 (NS1). Assay sensitivity was examined using sera from 27 patients with reverse transcription (RT)-PCR-confirmed and 85 with suspected ZIKV infection. Specificity was analysed using sera from 1,015 healthy individuals. Samples from 252 patients with dengue virus (n = 93), West Nile virus (n = 34), Japanese encephalitis virus (n = 25), chikungunya virus (n = 19) or Plasmodium spp. (n = 69) infections and from 12 yellow fever-vaccinated individuals were also examined. In confirmed ZIKV specimens collected ≥ 6 days after symptom onset, ELISA sensitivity was 58.8% (95% confidence interval (CI): 36.0–78.4) for IgM, 88.2% (95% CI: 64.4–98.0) for IgG, and 100% (95% CI: 78.4–100) for IgM/IgG, at 99.8% (95% CI: 99.2–100) specificity. Cross-reactivity with high-level dengue virus antibodies was not detected. Among patients with potentially cross-reactive antibodies anti-ZIKV positive rates were 0.8% (95% CI: 0–3.0) and 0.4% (95% CI: 0–2.4) for IgM and IgG, respectively. Providing high specificity and low cross-reactivity, the NS1-based ELISA has the potential to aid in counselling patients, pregnant women and travellers after returning from ZIKV-endemic areas.

Full Text Available We documented the types and degree of functional disability in 74 patients with AIDS at the Hospital de Clínicas of the Federal University of Paraná, Brazil. Few of these patients are referred for rehabilitation services and there is only a limited team approach in their care. We found that 91% of the patients had some degree of functional impairment; in 81% the complaint was weakness and in 47% it was neurological involvement. According to the Barthel Index, 79% were considered functionally independent, 14% partially dependent and 7% dependent. For most of them, independence requires effort and their quality of life is reduced. Severe disability was rather unusual, while mild or moderate disability levels were not. The functional physical disability found in 21% of the patients required management by a rehabilitation team. We conclude that it is important to focus attention on the quality of life of patients with AIDS.

This report describes the NASA Lexical Dictionary (NLD), a machine-aided indexing system used online at the National Aeronautics and Space Administration's Center for AeroSpace Information (CASI). This system automatically suggests a set of candidate terms from NASA's controlled vocabulary for any designated natural language text input. The system is comprised of a text processor that is based on the computational, nonsyntactic analysis of input text and an extensive knowledge base that serves to recognize and translate text-extracted concepts. The functions of the various NLD system components are described in detail, and production and quality benefits resulting from the implementation of machine-aided indexing at CASI are discussed.

Full Text Available Sexual relations hold an important place in the life and development of the individual. However, it can cause health risks such as HIV infection without done the necessary protective measures. The purpose of this study is to review sexual behaviors which increase HIV infection and AIDS risk. This sexual behavior expressed as: anal sex, one-night stand, sex without condoms, sex with older persons, concurrent sexual relationships, using alcohol and illegal drugs before or during intercourse, and starting sex at an early age. Because HIV is likely to rise in accordance with the increase in the number of people the person had sexual intercourse, especially concurrent sexual behavior and one-night stand, the most effective way to stay away from HIV/AIDS risk is to have sexual intercourse only with stable partners who know each other's sexual history and use condoms regularly.

Recently, new training techniques that involve the use of robots have been used in the rehabilitation of patients with hemiplegia and paraplegia. Robots used for training the arm include the MIT-MANUS, Arm Trainer, mirror-image motion enabler (MIME) robot, and the assisted rehabilitation and measurement (ARM) Guide. Robots that are used for lower-limb training are the Rehabot, Gait Trainer, Lokomat, LOPES Exoskeleton Robot, and Gait Assist Robot. Robot-aided therapy has enabled the functional training of the arm and the lower limbs in an effective, easy, and comfortable manner. Therefore, with this type of therapy, the patients can repeatedly undergo sufficient and accurate training for a prolonged period. However, evidence of the benefits of robot-aided training has not yet been established.

Although considerable attention has been placed on the role of prostitutes in the AIDS epidemic, little attention has been directed to features of prostitutes' work lives which are relevant to the control of AIDS. This article reviews several aspects of prostitution in the United States which have implications for control of the epidemic. The article first reviews the epidemiology of human immunodeficiency virus (HIV) infection among prostitutes. The legalized system of prostitution in Nevada serves as a basis for comparison to illegal prostitution. This article examines the effectiveness of mandatory testing of prostitutes for monitoring and controlling the epidemic. And finally, a peer education approach as a means to control HIV infection among prostitutes is explored.
