Butterflies in urban parks in the Bangkok Metropolitan Region, Thailand.

ABSTRACT: Background:For residents of East-Southeast Asia's megacities, interactions with "nature" may be largely limited to interactions taking place in urban parks. Urban parks provide refuges for ecologically-important biodiversity, such as insect pollinators. While residents may be unlikely to notice small insects, butterflies are more likely to be noticed and to provide positive human-"nature" interactions. Engaging residents and city planners in promoting habitat for butterflies is valid conservation practice and has well-understood educational and well-being benefits. Surveying and monitoring is an essential activity to corroborate, improve and communicate the outcomes of conservation practices amongst city governments, scientists and other stakeholders. Here we present the data from a survey of butterflies in urban parks in the megacity of the Bangkok Metropolitan Region as part of the "Urban biodiversity and human well-being in East-Southeast Asia's megacities" project organised by the "Urban Butterflies in Asia Research Network". New information:We recorded 51 species of butterflies from ten urban parks in the Bangkok Metropolitan Region. This was more than double the 25 species reported in Bangkok's City Biodiversity Index application. However, this was lower than that recorded in other megacities in Southeast Asia, such as Kuala Lumpur at 60 species. Most of the butterflies recorded were common and widespread species. DNA barcodes are provided for most of the butterflies sampled.

Project description:Canine filariasis is caused by several nematode species, such as Dirofilaria immitis, Dirofilaria repens, Brugia pahangi, Brugia malayi, and Acanthocheilonema reconditum. Zoonotic filariasis is one of the world's neglected tropical diseases. Since 2000, the World Health Organization (WHO) has promoted a global filarial eradication program to eliminate filariasis by 2020. Apart from vector control strategies, the infection control of reservoir hosts is necessary for more effective filariasis control. In addition, many studies have reported that Wolbachia is necessary for the development, reproduction, and survival of the filarial nematode. Consequently, the use of antibiotics to kill Wolbachia in nematodes has now become an alternative strategy to control filariasis. Previously, a case of subconjunctival dirofilariasis caused by Dirofilaria spp. has been reported in a woman who resides in the center of Bangkok, Thailand. Therefore, our study aimed to principally demonstrate the presence of filarial nematodes and Wolbachia bacteria in blood collected from domestic dogs from the Bangkok Metropolitan Region, Thailand. A total of 57 blood samples from dogs with suspected dirofilariasis who had visited veterinary clinics in Bangkok were collected. The investigations for the presence of microfilaria were carried out by using both microscopic and molecular examinations. PCR was used as the molecular detection method for the filarial nematodes based on the COI and ITS1 regions. The demonstration of Wolbachia was performed using PCR to amplify the FtsZ gene. All positive samples by PCR were then cloned and sequenced. The results showed that the filarial nematodes were detected in 16 samples (28.07%) using microscopic examinations. The molecular detection of filarial species using COI-PCR revealed that 50 samples (87.72%) were positive; these consisted of 33 (57.89%), 13 (22.81%), and 4 (7.02%) samples for D. immitis, B. pahangi, and B. malayi, respectively. While the ITS1-PCR showed that 41 samples (71.93%) were positive-30 samples (52.63%) were identified as containing D. immitis and 11 samples (19.30%) were identified to have B. pahangi, whereas B. malayi was not detected. Forty-seven samples (82.45%) were positive for Wolbachia DNA and the phylogenetic tree of all positive Wolbachia was classified into the supergroup C clade. This study has established fundamental data on filariasis associated with Wolbachia infection in domestic dogs in the Bangkok Metropolitan Region. An extensive survey of dog blood samples would provide valuable epidemiologic data on potential zoonotic filariasis in Thailand. In addition, this information could be used for the future development of more effective prevention and control strategies for canine filariasis in Thailand.

Project description:BackgroundHealthcare workers (HCW), who are crucial workforce, have experienced stress during the COVID-19 pandemic. They have been learning to fight against and support patients as much as possible. Thus, this study aims to account for the psychological impact of the COVID-19 outbreaks on the healthcare workers of medical school hospitals in terms of their perceived stress and coping styles.MethodThis cross-sectional study was conducted from June to August, 2021. 517 HCWs self-administered the online survey. Perceived Stress Scale (PSS-10) in Thai-version was used to examine the perceived stress symptoms. Brief-COPE score was used to determine the coping strategies. Independent sample t-test, one-way analysis of variance (ANOVA), and multivariable regression analysis were utilized. The level of significance was set at p-value < 0.05.ResultThe prevalence of perceived stress among the HCWs was 41.97%. Coping strategies were used to deal with stress during the outbreak for problem-solving (Mean ± SD = 0.25 ± 0.60) and positive attitude (Mean ± SD = 2.85 ± 0.62). Significant difference was observed in the use of coping strategies among those who differ in marital status (F2, 514 = 7.234, p-value = 0.001), having children (t515 = -4.175, p-value < 0.001), and days off (t515 = -1.992, p-value = 0.047). Multivariable regression analysis reported who those perceived stress symptoms using social support more than those normal stress (AOR 1.54, 95% CI 1.070-2.236, p-value = 0.02). The perceived stress symptoms group used the avoidance strategy 2.03 times more than the other group (AOR 2.03, 95% CI 1.406-2.934, p-value < 0.001). Interestingly, the participants who perceived stress symptoms applied a positive attitude strategy lesser than those who experienced normal stress (57.5%) (AOR 0.42, 95% CI 0.307-0.590, p-value < 0.001).ConclusionThe impact of the COVID-19 pandemic on mental distress remains. The findings of this study suggest further study to assess the HCWs' stress after the pandemic. HCWs should consider merging each of the coping strategies to balance work and lifestyle in pandemic situations.
