“…Three studies reported that difficulty in accessing health services resulted in some participants not seeking treatment for schistosomiasis [32, 37, 44]. A further three studies highlighted that dependence on external control measures in the area, for treatment of the disease, may result in health services not being used [26, 27, 44].…”

Schistosomiasis is a chronic and debilitating parasitic disease acquired through contact with infested freshwater. An essential component of its control is passive case finding, which, in order to be effective, requires a detailed understanding of health-seeking behaviour. This study aimed to systematically review evidence on health-seeking behaviour for schistosomiasis, in order to determine factors influencing use or non-use of modern health services for the infection. Quantitative, qualitative and mixed method studies reporting on factors related to seeking treatment from modern health services for schistosomiasis were obtained, combining electronic and hand searching. Data extraction and quality assessment of the included articles were performed, with all studies qualitatively analysed using thematic synthesis. A total of 19 studies were included in the review. Six themes were identified from the analysis: biomedical knowledge on schistosomiasis, perceptions of modern treatment and health services, financial considerations of treatment, perceptions on the symptoms, stigma of the infection, and physical location and community. These findings were consistent across studies of different design, setting and quality. Many of the themes identified echo existing literature on health-seeking behaviour. The synthesis also highlighted the role of stigma, and aspects of the physical location and community that may affect treatment-seeking for schistosomiasis. Health education programmes that intend to improve the utilisation of modern health services for the infection need to acknowledge the multiple determinants influencing their use. Future research should move beyond describing health-seeking behaviour to identifying the factors that underlay such behaviour.

“…36 Moreover, the local health services are poor, thus hindering the population's access to actions aimed at health promotion and disease prevention, control and treatment. 35 Thus, this evidence of clustering and combination patterns of metabolic syndrome components contributes towards the existing knowledge. It corroborates the usefulness of metabolic syndrome as a diagnostic tool with simple clinical-laboratory criteria that are easily applicable at the primary health care level, including isolated rural areas in one of the poorest regions of Brazil.…”

Clustering and combining pattern of metabolic syndrome components in a rural Brazilian adult population

CONTEXT AND OBJECTIVE: Metabolic syndrome is characterized by clustering of cardiovascular risk factors such as obesity, dyslipidemia, insulin resistance, hyperinsulinemia, glucose intolerance and arterial hypertension. The aim of this study was to estimate the probability of clustering and the combination pattern of three or more metabolic syndrome components in a rural Brazilian adult population. DESIGN AND SETTING: This was a cross-sectional study conducted in two rural communities located in the Jequitinhonha Valley, Minas Gerais, Brazil. METHODS:The sample was composed of 534 adults (both sexes). Waist circumference, blood pressure and demographic, lifestyle and biochemical characteristics were assessed. The prevalences of metabolic syndrome and its components were estimated using the definitions of the National Cholesterol Education Program -Adult Treatment Panel III. A binomial distribution equation was used to evaluate the probability of clustering of metabolic syndrome components. The statistical significance level was set at 5% (P < 0.05). RESULTS: Metabolic syndrome was more frequent among women (23.3%) than among men (6.5%). Clustering of three or more metabolic syndrome components was greater than expected by chance. The commonest combinations of three metabolic syndrome components were: hypertriglyceridemia + low levels of HDL-c + arterial hypertension and abdominal obesity + low levels of HDL-c + arterial hypertension; and of four metabolic syndrome components: abdominal obesity + hypertriglyceridemia + low levels of HDL-c + arterial hypertension. CONCLUSION:The population studied presented high prevalence of metabolic syndrome among women and clustering of its components greater than expected by chance, suggesting that the combination pattern was non-random. RESUMO CONTEXTO E OBJETIVO:A síndrome metabólica é caracterizada pela agregação de fatores de risco cardiovasculares como obesidade, dislipidemia, resistência à insulina, hiperinsulinemia, intolerância à glicose e hipertensão arterial. Este estudo objetivou estimar a probabilidade de agregação e o padrão de combinação de três ou mais componentes da síndrome metabólica em população rural adulta brasileira. TIPO DE ESTUDO E LOCAL: Estudo transversal, conduzido em duas comunidades rurais da região do Vale do Jequitinhonha, Minas Gerais. MÉTODOS: A amostra foi constituída de 534 adultos, de ambos os sexos, dos quais foram aferidas a circunferência da cintura, a pressão arterial e características demográficas, do estilo de vida e bioquímicas. Prevalências da síndrome metabólica e seus componentes foram estimados usando a definição da National Cholesterol Education Program -Adult Treatment Panel III. A equação da distribuição binomial foi utilizada para avaliar a probabilidade de agregação dos componentes da síndrome metabólica. O nível de significância estatística estabelecido foi 5% (P < 0,05). RESULTADOS: Síndrome metabólica foi mais frequente em mulheres (23,3%) que homens (6,5%). A agregação de três ou mais componentes da síndrome meta...

“…While these data from 2009 seem to indicate a reduction in the transmission of this disease in Brazil, there were 820 cases of the most severe forms between 2000 and 2010, with approximately 505 deaths in the period [2]. It is therefore clear that access of infected individuals to diagnosis and treatment remains limited [3].…”

Usnic Acid Potassium Salt: An Alternative for the Control of Biomphalaria glabrata (Say, 1818)

In Brazil, the snail Biomphalaria glabrata is the most important vector of schistosomiasis due to its wide geographical distribution, high infection rate and efficient disease transmission. Among the methods of schistosomiasis control, the World Health Organization recommends the use of synthetic molluscicides, such as niclosamide. However, different substances of natural origin have been tested as alternatives for the control or eradication of mollusks. The literature describes the antitumor, antimicrobial and antiviral properties of usnic acid as well as other important activities of common interest between medicine and the environment. However, usnic acid has a low degree of water solubility, which can be a limiting factor for its use, especially in aquatic environments, since the organic solvents commonly used to solubilize this substance can have toxic effects on aquatic biota. Thus, the aim of the present study was to test the potassium salt of usnic acid (potassium usnate) with regard to molluscicidal activity and toxicity to brine shrimp (Artemia salina). To obtain potassium usnate, usnic acid was extracted with diethyl ether isolated and purified from the lichen Cladonia substellata. Biological assays were performed with embryos and adult snails of B. glabrata exposed for 24 h to the usnate solution solubilized in dechlorinated water at 2.5; 5 and 10 µg/ml for embryos, 0.5; 0.9; 1;5 and 10 µg/ml for mollusks and 0.5; 1; 5; 10 µg/ml for A. salina. The lowest lethal concentration for the embryos and adult snails was 10 and 1 µg/ml, respectively. No toxicity to A. salina was found. The results show that modified usnic acid has increased solubility (100%) without losing its biological activity and may be a viable alternative for the control of B. glabrata.
