Intestinal parasitic infections: telephone health literacy with men in areas of poverty in the syndemic

OBJECTIVES

to assess Popular Health Education practices on intestinal parasites, carried out by telephone contact with men living in urban communities in Rio de Janeiro, Brazil, during the COVID-19 syndemic.

METHOD

a quasi-experimental, quantitative and descriptive study, carried out with men aged 20 to 59 years. Pre-test was applied, and participants were divided into two groups: control and experimental. Popular Education in Health practices were carried out with an experimental group, and post-test was applied for both.

RESULTS

health education practices were significant in the experimental group, with a reduction in incorrect answers. There was an increase in incorrect answers in the control group's post-test.

CONCLUSIONS

the Brazilian National Policy for Popular Education in Health contributed to qualify men's health literacy on intestinal parasites. Practice by telephone contact proved to be a powerful strategy for nursing and public policies to access this group and promote health in Primary Health Care.

Evaluation matrix for health promotion programs in socially vulnerable territories

Health promotion has a set of strategies for advancing health and reducing inequalities. However, evaluating the effectiveness of health promotion programs has been a challenge. This paper shows the development and application of the Evaluation Matrix, constructed with qualitative-quantitative and multidimensional indicators supported by public policies targeting socially vulnerable territories. This is a cross-sectional study with the implementation of a health promotion program in order to develop an Evaluation Matrix to be applied in two distinct socio-environmentally vulnerable areas. The Evaluation Matrix proved to be easily applicable and enabled the detection of strengths and weaknesses of health promotion programs applied in different territories. The participation of managers, teams, population and multiple sectors of society was decisive for the success of the program. Furthermore, community health workers stood out as essential stakeholders due to their linkages with the population. Contributions include a tool and methodology for evaluating health promotion programs to be applied in different territories and modified according to the territory.

Socioenvironmental conditions and intestinal parasitic infections in Brazilian urban slums: a cross-sectional study

Methods

A cross-sectional study covering an agglomeration of urban slums was conducted between 2015 and 2016 using participants observation, a socioeconomic survey, and the spontaneous sedimentation method with three slides per sample to analyze fresh stool specimens ( n =595) searching for intestinal parasites.

Results

Endolimax nana ( n =95, 16.0%) and Entamoeba coli ( n =65, 10.9%) were the most frequently identified agents, followed by Giardia intestinalis ( n =24, 4.0%) and Ascaris lumbricoides ( n =11, 1.8%). Coinfections caused by E. nana and E. histolytica/dispar and by Entamoeba coli/A. lumbricoides were significant. The use of piped water as drinking water, the presence of A. lumbricoides , and contamination with coliform bacteria and Escherichia coli were more common in major area (MA) 1. Children (0-19 years) had a greater chance of living in poverty (OR 3.36; 95% CI: 2.50- 4.52; p <0.001) which was pervasive. The predominance of protozoa parasites suggests that a one-size-fits-all approach focusing on preventive chemotherapy for soil-transmitted helminths is not appropriate for all communities in developing countries. It is important that both residents and health professionals consider the socioenvironmental conditions of urban slums when assessing intestinal parasitic infections for disease control and health promotion initiatives.

Environmental aspects related to tuberculosis and intestinal parasites in a low-income community of the Brazilian Amazon

We carried out a cross-sectional study from January to December 2015 on 1,425 inhabitants from a floating population in the Brazilian Amazon (Murinin district, Pará State) to describe the population-based prevalence of tuberculosis (TB) from 2011 to 2014, recent TB contacts (rCts) latently infected with Mycobacterium tuberculosis (LTBI) , the coverage of the local health network, socio-environmental factors, and frequency of intestinal parasitic infection (IPI). We found that the sanitary structure was inadequate, with latrines being shared with other rooms within the same accommodation; well water was the main source of water, and 48% of families had low incomes. The average rate of TB was 105/100, 000 inhabitants per year; one third of TB patients had been household contacts of infected individuals in the past, and 23% of rCts were LTBI. More than half (65%) of 44% of the stools examined (representing 76% of the housing) had IPIs; the highest prevalence was of fecal-oral transmitted protozoa (40%, Giardia intestinalis ), followed by soil-transmitted helminths (23%). TB transmission may be related to insufficient disease control of rCts, frequent relocation, and underreporting. Education, adopting hygienic habits, improving sanitation, provision of a treated water supply and efficient sewage system, further comprehensive epidemiological surveillance of those who enter and leave the community and resources for basic treatment of IPIs are crucial in combating the transmission of these neglected diseases.

New morphological data of Litomosoides chagasfilhoi (Nematoda: Filarioidea) parasitizing Nectomys squamipes in Rio de Janeiro, Brazil

Litomosoides chagasfilhoi, originally described by Moraes Neto, Lanfredi & De Souza (1997) parasitizing the abdominal cavity of the wild rodent, Akodon cursor (Winge, 1887), was found in the abdominal cavity of Nectomys squamipes (Brants, 1827), from the municipality of Rio Bonito, Rio de Janeiro State, Brazil. This study led to addition of new morphological data and a new geographical distribution for this filarioid in Brazil. Several characters were detailed and emended to previous records of L. chagasfilhoi in N. squamipes, and confirming the original description in A. cursor: buccal capsule longer than wide with walls thinner than the lumen, right spicule slightly sclerotized, with membranous distal extremity slender, with a small tongue-like terminal portion, left spicule with handle longer than the blade, whose edges form large membranous wings folded longitudinally.
