HIV/AIDS epidemic in the State of Amazonas: characteristics and trends from 2001 to 2012

A scoping review was conducted to describe the epidemiological characteristics of the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic in the State of Amazonas, Brazil, from 2001 to 2012, and temporary patterns were estimated from surveillance data. The results suggest that in its third decade, the Amazon HIV/AIDS epidemic is far from being stabilized and displays rising AIDS incidence and mortality rates and late diagnoses. The data suggest that AIDS cases are hitting mostly young adults and have recently shifted toward men, both homosexual and heterosexual. AIDS cases among the indigenous people have remained stable and low. However, the epidemic has disseminated to the interior of the state, which adds difficulties to its control, given the geographical isolation, logistical barriers, and culturally and ethnically diverse population. Antiretroviral (ARV) therapy has been decentralized, but peripheral ARV services are still insufficient and too distant from people who need them. Recently, the expansion of point-of-care (POC) rapid HIV testing has been contributing to overcoming logistical barriers. Other new POC devices, such as the PIMA CD4 analyzer, will bring the laboratory to the patient. AIDS uniquely coexists with other tropical infections, sharing their epidemiological profiles. The increased demand for HIV/AIDS care services can only be satisfied through increased decentralization to peripheral health units, which can also naturally integrate care with other tropical infections and can promote a shift from vertical to integrated programming. Future challenges involve building surveillance data on HIV case notification and covering the spectrum of engagement in care, including adherence to treatment and follow-up loss.

Prevalence of and factors influencing smoking among medical and non-medical students in Tbilisi, Georgia / Prevalência de tabagismo e fatores que o influenciam em estudantes de medicina e outros universitários em Tbilisi, Geórgia

OBJECTIVE: Smoking is a serious problem that has a devastating impact on health. The objective of this study was to describe the prevalence of and factors influencing smoking among medical and non-medical students in Tbilisi, Georgia, as well as to determine whether medical education has an impact on smoking. METHODS: A cross-sectional study was carried out at Tbilisi State Medical University and Tbilisi State University, both of which are located in Tbilisi, Georgia. A total of 400 4th-year students (200 students at each university) were asked to complete standardized questionnaires. RESULTS: Of the sample as a whole, 48.75% were identified as smokers and 51.25% were identified as nonsmokers. The mean age was 20.24 years among smokers and 20.26 years among nonsmokers. Of the medical students, 49.5% were smokers, as were 48.0% of the non-medical students. The male-to-female ratio in the study population was 0.9:1.1. Smoking was found to have a strong relationship with gender, males accounting for 65% of all smokers. Of the smokers, 56.9% stated that they would like to quit smoking (for health or financial reasons). Of the medical students, 59.5% expressed a willingness to quit smoking, as did 54.2% of the non-medical students. CONCLUSIONS: There is a need to improve smoking education for undergraduate students. Special attention should be given to the inclusion of anti-smoking education in undergraduate curricula, as well as to the implementation of smoking prevention campaigns at institutions of higher education. However, such measures will be effective only if tobacco control policies are strictly enforced on the national level as well. .

OBJETIVO: O tabagismo é um problema sério, cujo impacto na saúde é devastador. O objetivo deste estudo foi descrever a prevalência do tabagismo e os fatores que o influenciam em estudantes de medicina e outros universitários em Tbilisi, Geórgia, bem como determinar se a educação médica tem impacto no tabagismo. MÉTODOS: Foi realizado um estudo transversal na Universidade Médica Estadual de Tbilisi e na Universidade Estadual de Tbilisi, ambas em Tbilisi, Geórgia. Pedimos a 400 alunos de quarto ano (200 em cada universidade) que respondessem a questionários padronizados. RESULTADOS: Do total da amostra, 48,75% eram fumantes e 51,25% eram não fumantes. A média de idade dos fumantes foi de 20,24 anos e a dos não fumantes foi de 20,26 anos. Dos estudantes de medicina, 49,5% eram fumantes, assim como o eram 48,0% dos universitários que não estudavam medicina. A razão entre os gêneros masculino e feminino foi de 0,9:1,1. O tabagismo apresentou forte relação com o gênero; 65% dos fumantes eram do sexo masculino. Dos fumantes, 56,9% disseram que gostariam de parar de fumar (por motivos de saúde ou financeiros). Dos estudantes de medicina, 59,5% disseram que estavam dispostos a parar de fumar, assim como o disseram 54,2% dos universitários que não estudavam medicina. CONCLUSÕES: É preciso melhorar a educação sobre o tabagismo nas universidades. Deve-se dar atenção especial à inclusão de educação antitabagismo no currículo das universidades e à implantação de campanhas de prevenção ao tabagismo em instituições de ensino superior. Entretanto, essas medidas só serão eficazes se as políticas de controle do tabaco forem rigorosamente observadas também em nível nacional. .

Serodiagnosis of acute respiratory infections in children in Georgia.

OBJECTIVE: To investigate the etiology of acute respiratory infections in hospitalized children. METHODS: A total of 808 children were studied. Investigation of RSV, Adenovirus, Parainfluenza, Influenza A and B, C.trachomatis, C.pneumoniae, M. pneumonia and Legionella were performed with an ELISA for IgM, IgG and IgA antibodies detection. RESULTS: There were 496 males and 312 females giving a male: female ratio of 1.6:1. Ages range from 1 month to 15 years. The overall detection rate was 57.9%. The most frequently detected were: parainfluenza 12.6%, adenovirus 11.2%, influenza A 7.3%, RSV 6%, M. pneumoniae 5.4%, C.trachomatis 3.5% and mixed-infections 9.2%. Pneumonia was associated most frequently with adenovirus and mixed-infections; wheezing bronchitis--with adenovirus, RSV and M. pneumoniae; bronchitis--with parainfluenza and adenovirus, diseases of upper respiratory tract--with parainfluenza and adenovirus. Peak of the virus activity was during winter (influenza, parainfluenza, adenovirus, RSV) and autumn (parainfluenza, RSV). CONCLUSION: Viruses are the main causes of ARI in Georgian children. A better understanding of the etiology of ARI in all of the regions of the world may be helpful for timely decision of specific therapy, which can help pediatricians to estimate and manage children with ARI.
