Factors such as high rates of FSW patronage, low rates of condom use during commercial sex, having sex with both commercial and noncommercial sexual partners, and high rates of STD infection may promote a heterosexual epidemic in China.
BackgroundIn Southeast Asia, data on malaria treatment-seeking behaviours and related affecting factors are rare. The population of the Wa ethnic in Myanmar has difficulty in accessing formal health care. To understand malaria treatment-seeking behaviour and household-affecting factors of the Wa people, a cross-sectional study carried out in Shan Special Region II, Myanmar.MethodsThe two methods, questionnaire-based household surveys to household heads and in-depth interviews to key informants, were carried out independently. The proportion of treatment-seeking patterns was calculated. Logistic regression was used to determine affecting factors of treatment-seeking. Qualitative data were analysed by using Text Analysis Markup System.ResultsOverall, 87.5% of the febrile population sought treatment, but only 32.0% did so within 24 hours. The proportion accessing the retail sector (79.6%) was statistically significant higher (P<0.0001) than accessing the public sector (10.6%). Multivariable logistic regression analysis identified family income, distances from a health facility, family decision and patient characteristics being independently associated with delayed malaria treatment.ConclusionMalaria treatment-seeking behaviour is not appropriate, and affecting factors include health service systems, social and cultural factors in Wa State of Myanmar.
Adenotonsillectomy is associated with improvements in PSG, behavior, and QOL in children with OSAS. However, it may not resolve OSAS in all children. The efficacy and role of additional therapeutic options require more study.
The H3N2 vaccine strain (A/Panama/2007/99) for the 2003-2004 influenza season did not antigenically match the circulating A/Fujian/411/02-like H3N2 viruses and had reduced effectiveness against influenza outbreaks. A/Wyoming/03/2003, an A/Fujian-like virus, was recommended as the vaccine strain for the 2004-2005 season. A/Wyoming differed from A/Panama by 16 amino acids in the HA1 molecule. Reverse genetics was used to determine the minimal amino acid changes that were responsible for the antigenic drift from A/Panama to A/Wyoming. After substitutions of 2 of the 16 amino acids in the HA (H155T, Q156H), the A/Panama HA variant was antigenically equivalent to A/Wyoming as determined by hemagglutination inhibition and microneutralization assays using ferret postinfection antisera. Conversely, A/Wyoming containing the His-155 and Gln-156 residues from A/Panama was antigenically equivalent to A/Panama. These results indicated that only these two HA residues specified the antigenic drift from A/Panama to A/Wyoming; other amino acid differences between these two H3N2 viruses had minimal impact on virus antigenicity but impacted virus replication efficiency in eggs.
Chinese MSM are at risk for HIV/STD infection and potential transmission of HIV to the general population. In addition to sexual risk reduction among MSM, reduction of homosexuality- related stigma should be part of effective intervention efforts. Volunteers from the MSM community and health care workers in primary health care system may serve as valuable resources for HIV/STD prevention and control among MSM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
