Неравенство доходов в различных секторах экономики Вьетнама: анализ структурных связей

Несмотря на выдающиеся достижения в области сокращения бедности, неравенство доходов во Вьетнаме по-прежнему имеет тенденцию к увеличению, оказывая негативное влияние на устойчивое развитие страны. Цель исследования — выявление и измерение влияния секторов экономики на доходы различных групп населения; полученные данные могут быть использованы для снижения уровня бедности во Вьетнаме. Связь между секторами экономики и распределением доходов населения Вьетнама была выявлена при помощи методологии анализа структурных связей, основанной на матрице социальных счетов за 2016 г., которая до сих пор не получила широкого применения среди вьетнамских ученых. По сравнению с предыдущими работами, данное исследование проведено на уровне страны, а не региона. Также были подробно описаны факторы, влияющие на распределение доходов, такие как секторы экономики, трудовые ресурсы и группы населения. Анализ выявил, что распределение большей части доходов 25 секторов экономики происходит по 513 потокам. При расширении секторов экономики вследствие политических изменений повышение доходов населения в основном зависит от таких показателей, как квалификация работников, капитал и масштаб межотраслевых связей. Примечательно, что на доходы городских домохозяйств существенное влияние оказывает показатель «высококвалифицированный труд», в то время как капитал является наиболее важным фактором, влияющим на доходы сельских домохозяйств. Согласно проведенному анализу, 32 потока наиболее значимо влияют на доходы населения. Важную роль в борьбе с бедностью играют следующие секторы экономики: лесное хозяйство, древесина и изделия из древесины, рыболовство, добыча угля, сырой нефти и природного газа, производство обуви, поставки электроэнергии, газа, воды и коммунальных услуг, а также розничная и оптовая торговля. Полученные данные послужили основой для рекомендаций в области сокращения неравенства доходов

The Association Between Ambient Temperatures and Hospital Admissions Due to Respiratory Diseases in the Capital City of Vietnam

This study aimed to examine the short-term effects of ambient temperature on hospital admissions due to respiratory diseases among Hanoi residents. We collected 34,653 hospital admissions for 365 days (November 1, 2017, to November 31, 2018) from two hospitals in Hanoi. A quasi-Poisson regression model with time series analysis was used to explore the temperature-health outcome relationship's overall pattern. The non-linear curve indicated the temperatures with the lowest risk range from 22 degrees (Celcius) to 25 degrees (Celcius). On average, cold temperatures showed a higher risk than hot temperatures across all genders and age groups. Hospital admissions risk was highest at 13 degrees (Celcius) (RR = 1.39; 95% CI = 1.26–1.54) for cold effects and at 33 degrees (Celcius) (RR = 1.21, 95% CI = 1.04–1.39) for the hot effects. Temporal pattern analysis showed that the most effect on respiratory diseases occurred at a lag of 0 days for hot effect and at a lag of 1 day for cold effect. The risk of changing temperature among women and people over 5 years old was higher than other groups. Our results suggest that the risk of respiratory admissions was greatest when the temperature was low. Public health prevention programs should be enhanced to improve public awareness about the health risks of temperature changes, especially respiratory diseases risked by low temperatures

A Bibliometric Analysis of the Global Research Trend in Child Maltreatment

Child maltreatment remains a major health threat globally that requires the understanding of socioeconomic and cultural contexts to craft effective interventions. However, little is known about research agendas globally and the development of knowledge-producing networks in this field of study. This study aims to explore the bibliometric overview on child maltreatment publications to understand their growth from 1916 to 2018. Data from the Web of Science Core Collection were collected in May 2018. Only research articles and reviews written in the English language were included, with no restrictions by publication date. We analyzed publication years, number of papers, journals, authors, keywords and countries, and presented the countries collaboration and co-occurrence keywords analysis. From 1916 to 2018, 47, 090 papers (53.0% in 2010–2018) were published in 9442 journals. Child Abuse & Neglect (2576 papers; 5.5%); Children and Youth Services Review (1130 papers; 2.4%) and Pediatrics (793 papers, 1.7%) published the most papers. The most common research areas were Psychology (16, 049 papers, 34.1%), Family Studies (8225 papers, 17.5%), and Social Work (7367 papers, 15.6%). Among 192 countries with research publications, the most prolific countries were the United States (26, 367 papers), England (4676 papers), Canada (3282 papers) and Australia (2664 papers). We identified 17 authors who had more than 60 scientific items. The most cited papers (with at least 600 citations) were published in 29 journals, headed by the Journal of the American Medical Association (JAMA) (7 papers) and the Lancet (5 papers). This overview of global research in child maltreatment indicated an increasing trend in this topic, with the world’s leading centers located in the Western countries led by the United States. We called for interdisciplinary research approaches to evaluating and intervening on child maltreatment, with a focus on low-middle income countries (LMICs) settings and specific contexts

The Vietnam Initiative on Zoonotic Infections (VIZIONS): A Strategic Approach to Studying Emerging Zoonotic Infectious Diseases

The effect of newly emerging or re-emerging infectious diseases of zoonotic origin in human populations can be potentially catastrophic, and large-scale investigations of such diseases are highly challenging. The monitoring of emergence events is subject to ascertainment bias, whether at the level of species discovery, emerging disease events, or disease outbreaks in human populations. Disease surveillance is generally performed post hoc, driven by a response to recent events and by the availability of detection and identification technologies. Additionally, the inventory of pathogens that exist in mammalian and other reservoirs is incomplete, and identifying those with the potential to cause disease in humans is rarely possible in advance. A major step in understanding the burden and diversity of zoonotic infections, the local behavioral and demographic risks of infection, and the risk of emergence of these pathogens in human populations is to establish surveillance networks in populations that maintain regular contact with diverse animal populations, and to simultaneously characterize pathogen diversity in human and animal populations. Vietnam has been an epicenter of disease emergence over the last decade, and practices at the human/animal interface may facilitate the likelihood of spillover of zoonotic pathogens into humans. To tackle the scientific issues surrounding the origins and emergence of zoonotic infections in Vietnam, we have established The Vietnam Initiative on Zoonotic Infections (VIZIONS). This countrywide project, in which several international institutions collaborate with Vietnamese organizations, is combining clinical data, epidemiology, high-throughput sequencing, and social sciences to address relevant one-health questions. Here, we describe the primary aims of the project, the infrastructure established to address our scientific questions, and the current status of the project. Our principal objective is to develop an integrated approach to the surveillance of pathogens circulating in both human and animal populations and assess how frequently they are exchanged. This infrastructure will facilitate systematic investigations of pathogen ecology and evolution, enhance understanding of viral cross-species transmission events, and identify relevant risk factors and drivers of zoonotic disease emergence

Safety and efficacy of fluoxetine on functional outcome after acute stroke (AFFINITY): a randomised, double-blind, placebo-controlled trial

Background Trials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to show if daily oral fluoxetine for 6 months after stroke improves functional outcome in an ethnically diverse population. Methods AFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial done in 43 hospital stroke units in Australia (n=29), New Zealand (four), and Vietnam (ten). Eligible patients were adults (aged ≥18 years) with a clinical diagnosis of acute stroke in the previous 2–15 days, brain imaging consistent with ischaemic or haemorrhagic stroke, and a persisting neurological deficit that produced a modified Rankin Scale (mRS) score of 1 or more. Patients were randomly assigned 1:1 via a web-based system using a minimisation algorithm to once daily, oral fluoxetine 20 mg capsules or matching placebo for 6 months. Patients, carers, investigators, and outcome assessors were masked to the treatment allocation. The primary outcome was functional status, measured by the mRS, at 6 months. The primary analysis was an ordinal logistic regression of the mRS at 6 months, adjusted for minimisation variables. Primary and safety analyses were done according to the patient's treatment allocation. The trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12611000774921. Findings Between Jan 11, 2013, and June 30, 2019, 1280 patients were recruited in Australia (n=532), New Zealand (n=42), and Vietnam (n=706), of whom 642 were randomly assigned to fluoxetine and 638 were randomly assigned to placebo. Mean duration of trial treatment was 167 days (SD 48·1). At 6 months, mRS data were available in 624 (97%) patients in the fluoxetine group and 632 (99%) in the placebo group. The distribution of mRS categories was similar in the fluoxetine and placebo groups (adjusted common odds ratio 0·94, 95% CI 0·76–1·15; p=0·53). Compared with patients in the placebo group, patients in the fluoxetine group had more falls (20 [3%] vs seven [1%]; p=0·018), bone fractures (19 [3%] vs six [1%]; p=0·014), and epileptic seizures (ten [2%] vs two [<1%]; p=0·038) at 6 months. Interpretation Oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and epileptic seizures. These results do not support the use of fluoxetine to improve functional outcome after stroke

Degradation of Poly (3-Hydroxybutyrate) (PHB) by Bacillus gelatini isolated from Vietnam

Poly (3-hydroxybutyrate) (PHB) is a natural polymer produced by many bacteria as a means to store carbon and energy. PHB have attracted commercial biotechnological interest because of their biodegradability and biocompatibility. Several aerobic and anaerobic PHB-degrading microorganisms have been isolated from soil, activated and aerobic sludge, seawater and lake water. The percentage of PHB-degrading microorganisms in the environment was estimated to be 0.5 - 9.6% of the total colonies. Majority of the PHB-degrading microorganisms were isolated at ambient or mesophilic temperatures and a few of them were able to degrade PHB at higher temperature. The composting at high temperature is one of the most promising technologies for recycling biodegradable plastics and the thermophilic microorganisms that could degrade polymers play an important role in the composting process. Thus, microorganisms that are capable of degrading various kinds of polyesters at high temperatures are of interest. In this study, we have isolated 11 thermophilic PHB-degrading bacteria strains. Among them strain B2 was able to use PHB as a carbon source for growth at high temperature (50oC). This bacteria grew at temperatures between 37 - 60oC, at NaCl concentration between 0.5 - 3% and at pH between 5 - 8. This strain was able to used sucrose, D-glucose, fructose, mannose... but not used D (+) glucosamin. This strain produced some extracellular enzymes such as cellulase, protease, catalase but not amylase.16S rDNA sequence analysis of strain B2 indicated that this novel isolation was related phylogenetically of Bacillus genus. Base on phenotypic, chemotaxonomic and phylogenetic results for strain B2, we describe a novel species named Bacillus gelatini. After 30 days of cultivation in the media with the concentration of PHB in the range of 1-2 g/l, B. gelatini degraded more than 50% total amount of PHB added. Strain B. gelatini can degrade not only PHB but also PLA, PCL at the rate of more than 20% after 20 days cultivation. For further studies, the purification of an extracellular PHB depolymerase from B. gelatini is necessary
