Numerous studies in different capital markets show that stock prices in initial public offerings change after a very short time, resulting in significant and unusual returns, which are referred to as underpricing of initial public offerings. Considering that previous studies, which are mainly based on the theory of information asymmetry and behavioral biases, have considered various and sometimes contradictory reasons as the cause of this phenomenon. This study aims to provide a comprehensive model of the factors explaining this abnormal return. Also, the role of accounting information in explaining this phenomenon is investigated.To discover these factors, the researcher studies the subject literature extensively, uses the qualitative method of theme analysis and interviews experts to extract their opinions. Then extracting repetitive patterns among the opinions and classifying them, the researcher develops a comprehensive model of factors affecting stock price in initial public offerings.In the model presented in this research, four factors of shortcomings of the initial supply process, fundamental factors, behavioral aspects and information content in the initial public offerings lead to underpricing in such a way that by intervening of regulatory bodies in the supply and demand mechanism, pricing errors occur and fundamental factors are not reflected in offering prices. Investors' behavioral aspects and insufficient accounting information content intensify this matter.According to the research findings, those shareholders who analyze the available information, especially accounting information, can gain abnormal returns. Also, the need to provide prospective accounting information in an initial public offering to determine the real share price leads to an increase in accounting information content.

Background: Strongyloidiasis, caused by the nematodes Strongyloides stercoralis and Strongyloides fuelleborni, is estimated to affect over 600 million individuals worldwide. The disease is endemic in Southeast Asia, where a warm-humid climate and socio-economic conditions maintain the parasite's life cycle and transmission. However, the current diagnostic methods may not be sufficiently sensitive, suggesting that the true prevalence of strongyloidiasis could be seriously underestimated in this. This study aims to determine the prevalence of strongyloidiasis in Southeast Asia through a systematic review and meta-analysis and to discuss the implications of the estimated prevalence on diagnostic approaches and control strategies., Methods: Following PRISMA guidelines, we conducted a systematic literature search in PubMed and Google Scholar databases to identify studies reporting Strongyloides prevalence data in the 11 Southeast Asian countries up to December 2022. A random effects model was employed to estimate the pooled prevalence of S. stercoralis at both regional and country levels., Results: Out of 3722 articles identified, 224 met our inclusion criteria. For S. stercoralis specifically, we found 187 articles, of which 52.4% were from Thailand. All Southeast Asian countries, except Brunei, had at least one study on Strongyloides prevalence. The estimated pooled prevalence of S. stercoralis regionally was 12.7% (95% CI 10.70-14.80%), ranging from 0.4 to 24.9% at the country level. Cambodia had the highest pooled prevalence (24.9%, 95% CI 15.65-35.38%), followed by Lao PDR (16.5%, 95% CI 9.50-24.95%). Moreover, we obtained a pooled prevalence of 10% (95% CI 7.06-13.52%) in a group comprising immigrants, workers, and veterans from Southeast Asian countries. S. stercoralis infects various host types, including nonhuman primates, domestic dogs and cats, rodents, and transport carriers such as cockroaches and vegetables., Conclusions: A high prevalence of strongyloidiasis in Southeast Asia was revealed, highlighting the importance of the region's ongoing research, surveillance, and control efforts. Factors contributing to the strongyloidiasis transmission include the role of animal hosts, the impact of global connectivity, and the significance of the co-endemicity of other Strongyloides species. Based on these findings, a multi-pronged One-Health approach is essential for sustainable intervention and control., (© 2023. National Institute of Parasitic Diseases.)

Toxoplasmosis and brucellosis are zoonotic diseases of worldwide distribution. They both cause abortion and infertility in human and animals. Limited data are available about these pathogens in Somali people and their animals. Hence, this study has evaluated the prevalence of anti- Toxoplasma gondii and anti- Brucella spp. antibodies in pregnant women in Mogadishu, Somalia. Serum samples from 307 pregnant women from Mogadishu, Somalia were tested for anti- T. gondii antibodies by Latex Agglutination Test (LAT) and anti- Brucella spp. antibodies by Rose Bengal Plate Test (RBPT) and a commercial competitive-ELISA (cELISA). A total of 119/307 (38.76%) pregnant women had a prior history of abortion. A total of 159/307 (51.79%; 95% CI: 46.2-57.35%) pregnant women were seroreactive for T. gondii by LAT at different stages of pregnancy. For Brucella spp., when RBPT and cELISA were combined 4/307 (1.30%; 95% CI: 0.36-3.30%) pregnant women were seroreactive to anti- Brucella spp. antibodies, being 2/307 (0.65%; 95% CI: 0.18-2.34%) by RBPT and 3/307 (0.98%; 95% CI: 0.33-2.83%) by cELISA. Two women were seroreactive for both agents. A high seropositivity to T. gondii and low seropositivity to Brucella spp. have been found in pregnant women from Mogadishu, Somalia. Considering the high number of abortions in the country associated to the fact that awareness on other zoonotic abortifacient pathogens in Somalis is very low, further studies should be conducted to evaluate the potential causes of abortions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Yusuf, Hassan-Kadle, Ibrahim, Hassan-Kadle, Yasin, Khojaly, Garcia and Vieira.)

Background: Begging and destitution constitute serious health and social problems in low and middle-income countries (LMICs)., Objectives: The objective of this study was to assess the trainability of beggars and the destitute in Abakaliki Nigeria in order to provide scientific evidence required for the development of a policy on their health, vocational rehabilitation and social reintegration., Methods: The study was a cross-sectional descriptive survey of 50 purposively selected beggars and destitute persons identified from motor parks, church cathedrals, market places etc. Data was collected using a structured interviewer-administered questionnaire. Analysis was based on mean rating (MNR), median rating (MDR), and range. Interview of each respondent lasted approximately 20 minutes., Results: Of the 50 respondents who participated in this study, 17 (34%) were females. Most subjects were of age category 31-35 years (30%) and 36-40 years (34%). Fifteen (30%) admitted having sight impairment while 17 (34%) admitted that they were physically challenged. The outcome of the trainability assessment showed relatively high mean ratings (MNRs) ranging from 3.42-4.06 on a scale of 5 points., Conclusion: The findings of this study clearly suggest that there is a very high potential for the vocational rehabilitation and social reintegration of beggars and the destitute in the study area., (© 2019 Nweze et al.)

To improve the stool concentration procedure, we modified different steps of the standard formalin-ether concentration technique and evaluated these modifications by examining stool samples collected in the field. Seven samples were found positive by the modified formalin-ether concentration technique (M-FECT). Therefore, the M-FECT procedure provides enhanced detection of Cryptosporidium oocysts., (Copyright © 2014 Elsevier B.V. All rights reserved.)

Permanent staining of faecal smears by Wheatley's trichrome technique has been used by many scientists for the detection of parasites in the past and it was found to be highly sensitive. This study was conducted to evaluate the use of Wintergreen oil in comparison with xylene in Wheatley's trichrome staining technique, as the reference technique. In a blind comparison study, 500 collected faecal samples from aboriginal communities were examined. Wintergreen oil was found to be more superior than xylene as a clearing agent in the Wheatley's trichrome staining of polyvinyl alcohol-fixed faecal smears for the identification of intestinal protozoa. Elimination of toxic, carcinogenic, and fire hazards makes Wintergreen oil the preferred choice in routine parasitology examinations., (Copyright © 2012 Elsevier B.V. All rights reserved.)

The flagellate protozoan parasite, Giardia intestinalis, is widely distributed throughout the world with a high prevalence in developing countries in the tropics and subtropics, including Malaysia. Approximately 200 million people are infected with the parasite globally, with 500,000 new cases reported annually. This cross-sectional study was conducted among three tribes of Orang Asli communities in Selangor, Perak and Pahang states of Malaysia. The main objective was to determine the prevalence of and risk factors for giardiasis. Stool samples were collected from 500 individuals aged between 2 and 74 years (males=219, females=281). The samples were examined with formalin-ether sedimentation and trichrome staining techniques. Socioeconomic data were collected through a pre-tested questionnaire. The overall prevalence of giardiasis was 20.0% with the highest prevalence in the Proto-Malays (33.3%) followed by Negritos (20.1%) and Senois (10.4%). The positive cases showed a decrease with increasing age and most of the positive cases were observed in individuals less than 24 years old. Males had significantly higher prevalence than females (χ(2)=5.283, P=0.022). Logistic regression analysis of the overall population studied and the Senoi tribe confirmed that being a child aged less than 15 years, being male, the consumption of raw vegetables and the presence of other family members infected with G. intestinalis were the main risk factors for giardiasis. The presence of other family members infected with G. intestinalis was the only risk factor highlighted in the Proto-Malay and Negrito tribes. Diarrhoea was significantly associated with giardiasis. However, the cause and effect relationship has yet to be determined. Thus, screening family members and treating the infected individuals are the main strategies that should be adopted by the public health authority in combating this infection in Orang Asli communities as well as health education regarding good personal and food hygiene practises., (Copyright © 2012 Australian Society for Parasitology Inc.
