RESUMO

BACKGROUND: People with Huntington's disease (HD) have increased functional and cognitive dependence. While numerous clinical, genetic, and therapeutic management studies have been carried out, few studies have investigated the disease from the personal experience and the context of people living with HD. To better serve these patients, our purpose is to understand, from the perspective of the patient and their families, how people with HD cope with their daily lives outside the clinical setting. METHODS: Thirty-three affected or at-risk people participated in this study. Participants were interviewed at their homes on distinct occasions during a family visit. We analyzed the data using Grounded Theory, which allowed us to understand how people live with the disease on their own terms. RESULTS: Living with HD is a process that begins with acceptance or denial that one is at risk for the disease or, growing awareness of the condition due to motor, behavioral, and cognitive changes, and, finally, loss of autonomy with physical dependence on another person, and loss of sense of self and family. CONCLUSION: While the daily life of patients before disease onset was characterized by physical and mental/cognitive independence, with HD they become increasingly trapped in their bodies, and their complications are due to the lack of effective curable therapy.

RESUMO

Salmonellosis is a foodborne disease caused by Salmonella spp. Although cell culture is the gold standard for its identification, validated molecular methods are becoming an alternative, because of their rapidity, selectivity, and specificity. A simplex and duplex droplet digital polymerase chain reaction (ddPCR)-based method for the identification and quantification of Salmonella using ttr, invA, hilA, spaQ, and siiA gene sequences was validated. The method has high specificity, working interval between 8 and 8,000 cp/µL in ddPCR reaction, a limit of detection of 0.5 copies/µL, and precision ranging between 5 and 10% measured as a repeatability standard deviation. The relative standard measurement uncertainty was between 2 and 12%. This tool will improve food safety in national consumption products and will increase the competitiveness in agricultural product trade.
