Effect of peer intervention by popular opinion leaders among young students who have sex with men / 中国学校卫生

Objective@#The proposal of this study is to determine the feasibility of using online social software to guide popular opinion leaders(POLs) among young students MSM (men who have sex with men, MSM) carrying out comprehensive AIDS prevention in young students MSM.@*Methods@#From November to December 2019 in Tianjin, 22 POLs who had previously experienced AIDS prevention education and training foucus on life skills were recruited. Though snowball sampling method, 100 POLs partners (friends, sexual partners, classmates, etc) were invited into the study. From January to March 2020, regular posters will be sent through the WeChat platform to guide POL to intervene their partners/sexual partners. The questionnaire surveys were conducted before and after the intervention.@*Results@#After the intervention, both the proportion of young students MSM had sex and with multiple sex partners decreased(χ2=12.12, 5.94, P<0.05). The comprehensive ability of AIDS prevention has improved significantly, the "National Eight Items" correct rate has risen from 90.0% to 99.0%(χ2=5.82, 7.56, P<0.05), and the "Youth Eight Items" correct rate has increased from 86.0% to 98.0%(P<0.01). Knowledge score increased from(11.08±1.89) to (11.84±1.27); Attitude score increased from (54.29±4.01) to (56.06±3.75), the behavior score increased from (52.12±4.78) to (55.08±4.25), skill score increased from (51.96±4.75) to (54.67±5.04), The comprehensive prevention ability score (percent) increased from (87.30±6.95) to (91.86±5.42)(t=-4.21, -3.51, -5.32, -5.16, -6.45, P<0.01).@*Conclusion@#Using Wechat platform to guide POL carrying out comprehensive AIDS prevention is effective for improving the comprehensive AIDS prevention ability of young students MSM.

Toxoplasmose gástrica em paciente infectado pelo vírus da imunodeficiência humana. Relato de caso / Gastric toxoplasmosis in patient infected with human immunodeficiency virus. Case report

A toxoplasmose é uma zoonose altamente disseminada. A maio­ria das infecções em imunocompetentes é assintomática. Porém, em pacientes imunodeprimidos, a infecção adquire um curso variável. Em pacientes com contagem de CD4 abaixo de 100 e que foram previamente expostos ao Toxoplasma gondii, pode haver reativação da doença em diversos tecidos. Envolvimento do trato gastrintestinal por Toxoplasma gondii é raramente relatado. Embora os sintomas gastrintestinais sejam comuns entre os pacientes com síndrome da imunodeficiência adquirida, a maioria é causada por infecções entéricas que não o Toxoplasma gondii. O objetivo deste estudo foi relatar um caso raro de toxoplasmose gástrica. Paciente do gênero feminino, 38 anos, com diagnóstico recente de vírus da imunodeficiência humana, iniciou sintomas gástricos inespecíficos como: epigastralgia, náuseas, vômitos e perda ponderal. O diagnóstico definitivo foi fechado com o estudo anatomopatológico da lesão na mucosa gástrica. Foi instituído tratamento para a toxoplasmose com clindamicina, pirimetamina e ácido folínico (devido à mielotoxicidade), com melhora parcial dos sintomas. Embora raro, a toxoplasmose gástrica deve entrar no diagnóstico diferencial de dor epigástrica em pacientes portadores da síndrome da imunodeficiência adquirida com contagem de CD4 baixa. Seu diagnóstico pre­suntivo pode ser dado pelo quadro clínico, mas o diagnóstico definitivo é obtido pela biópsia da lesão...

Toxoplasmosis is a highly disseminated zoonosis. Most infections are asymptomatic in immunocompetent patients. However, in immunocompromised patients, infection acquires a variable course. In patients with CD4 counts lower than 100 and who have been previously exposed to Toxoplasma gondii, there may be reactivation of the disease in various tissues. Involvement of the gastrointestinal tract by Toxoplasma gondii is rarely reported. Although gastrointestinal symptoms are common among patients with acquired immunodeficiency syndrome, most are caused by enteric infections other than Toxoplasma gondii. The aim of this study was to report a rare case of gastric toxoplasmosis. A 38-year-­old female patient, recently diagnosed with immunodeficiency human virus, presented with nonspecific gastric symptoms such as epigastric pain, nausea, vomiting and weight loss. The definitive diagnosis was reached with anatomopathological examination of gastric mucosa damage. She was treated for toxoplasmosis with clindamycin, pyrimethamine and folinic acid (due to myelotoxicity), with partial improvement of symptoms. Although rare, gastric toxoplasmosis should enter the differential diagnosis of epigastric pain in patients with acquired immunodeficiency syndrome with low CD4 count. Its presumptive diagnosis can be made on a clinical basis, but the definitive diagnosis is reached with biopsy...

Status and demand on HIV/AIDS control among men who have sex with men in main districts of Chongqing / 第二军医大学学报

Objective: To survey the knowledge, attitude and behavior about HIV/AIDS among men who have sex with men (MSM) in the main districts of Chongqing and to analyze the current status and demand on HIV/AIDS control in the districts. Methods: Questionnaire survey was conducted among MSM, and qualitative interviews of MSM and some key informants, including the centers for disease control and prevention (CDC) staff, volunteers and the owners of bars or public bathrooms were done. Results: About 80% of MSM were younger than 30 years old and were unmarried. More than half of MSM had college degree or above. Most of them were students, office staff and entertainment staff, and about 25% of them were bisexual. Television and newspapers were the main pathways to obtain knowledge on HIV/AIDS; friends, free publicity materials, internet and consulting services were also ways to obtain related knowledge. It was found that in the recent six months, 6.5%(50/772) of MSM sold and 3.9%(30/772) bought sexual services, and about 17.1% (132/772) MSM had sex with women in the recent six months. The rates of condom use among MSM when having sex with men and women at every intercourse were 41.9%(271/647) and 29.5%(39/132), respectively. And 82.0%(633/772) of them had intervention service. MSM suggested that their privacy should be fully protected during the intervention, more attractive publicity materials should be provided, and more knowledge was needed on other sex transmitted diseases; the intervention ways should be diversified; and they needed the consultation of professional. The volunteers required more training and independent offices. The owners of entertainment argued that more efforts should be made to encourage the entertainment workers to promote intervention. Conclusion: MSM in the main district of Chongqing have many high risk factors of HIV/AIDS. Though various interventions have been given and some achievement has been made, more efforts are needed to protect the privacy of MSM population and to improve the intervention. And efforts should also be made to promote the initiation of the volunteers, entertainment owners and staff.
