ABSTRACT
@#There was an increasing trend in dengue infection in Malaysia with many outbreaks that occurred in Petaling District, Selangor in 2013 – 2014. A high rise apartment in Petaling Jaya reported ten episodes of dengue outbreaks from June 2013 to June 2014. We studied the prolonged dengue hotspot at this residential complex in Petaling Jaya, Selangor and made recommendations to prevent future prolonged dengue outbreaks. This was a retrospective exploratory study by analysing secondary data on dengue outbreaks from years 2013 to 2014. Small group discussions, interview sessions with staff and site visits were carried out to obtain necessary information. Two hundred and ninety-one cases were notified during the dengue outbreaks from Epid week (EW) 25 in 2013 to EW 26 in 2014 with no mortality reported. Information entered into dengue databases might be incomplete or mixed up. Active case detection and environmental risks assessment based on cases were not carry out due to the massive outbreak. Basic information on the population in the outbreak locality was unavailable. Various control activities were carried out with varying outcomes. Community participation was poor with little cooperation from residents during health education and community-based mosquito breeding prevention activities. To ensure better management of dengue outbreaks and to prevent prolonged dengue outbreaks in the future, integrated case findings, effective control activities, extensive environmental assessment on the outbreak locality and adopting innovative community outreach initiative with sufficient staff are required to curb dengue vector.
ABSTRACT
Objective: To analyze potential activation of oxidative stress tolerance systems by SAB E-41 bacterial extract in promoting the life span of yeast Schizosaccharomyces pombe. Methods: In vitro analysis was done to assess antioxidant activity of SAB E-41 bacterial extract. Antiaging property of the particular extract was then assayed through spot test and chronological life span assays. Furthermore, sty1 mitogen-activated protein kinase, pap1 transcriptional factor of oxidative stress response and its downstream genes, ctt1 were evaluated via real time PCR. The protein level of ctt1 was then observed via Western Blot analysis. In addition, accumulation of reactive oxygen species and mitochondrial activity were conducted to understand the effect of SAB E-41 upon oxidative stress response systems in vivo. Results: The IC
ABSTRACT
Background: The restless legs syndrome (RLS) is a movement disorder characterized by an imperative urge to move the legs, associated with paraesthesias, motor restlessness and worsening of symptoms at night with at least partial relief by activity. Its prevalence ranges between 2-15 percent of general adult population and 20-30 percent of uremic patients. Aim: To evaluate the frecuency and the clinical features of RLS in a sample of general adult population and in uremic patients, in Chile, correlating it with biochemical parameters. Method: 100 relatives of outpatients and 166 uremic patients undergoing chronic haemodialysis were interviewed assessing the presence and severity of RLS according to current diagnostic criteria. Biochemical parameters assessed were hematocrit, serum ferritin, phosphate, intact parathyroid hormone (iPTH) levels. Results: 13 percent of the general population sample was affected, 15 percent of them were severe. Forty three cases were found among uremic patients (25.9 percent) (p <0.01 vs general population), 60 percent of them were severe and women were affected with higher frequency (p <0.05) and severity (p <0.01). Four patients presented RLS even during hemodialysis. No correlation was found with biochemical parameters. Most RLS cases had not been diagnosed previously. Conclusions: In our population RLS is common and undetected. It is especially prevalent and severe in uremic patients: we found no evidence that anaemia, iron deficiency or iPTH level play a major pathogenic role. Our findings emphasize the need of greater medical awareness of RLS because available therapy may improve the quality of life
