RESUMEN

The COVID-19 pandemic is spreading fast globally. Vietnam's strict containment measures have significantly reduced the spread of the epidemic in the country. This was achieved through the use of emergency control measures in the epidemic areas and integration of resources from multiple sectors including health, mass media, transportation, education, public affairs, and defense. This paper reviews and shares specific measures for successful prevention and control of COVID-19 in Vietnam, which could provide useful learning for other countries.

RESUMEN

BACKGROUND: The rapid and widespread development of social networking sites has created a venue for an increase in cyberbullying among adolescents. Protective mechanisms and actions must be considered, such as how proximal family factors can prevent self-harm and suicidal behaviors among adolescents exposed to cyberbullying. The present study examined the associations among cyberbullying, parental attitudes, self-harm, and suicidal behaviors after adjusting for confounding factors. METHODS: Data were obtained from a school-based survey of randomly selected grade 6 students (11 years old) performed in Hue City, Vietnam, in 2018. A total of 648 students were interviewed face-to-face using a structured questionnaire based on the Global School-based Student Health Survey (GSHS). Univariate, multivariable logistic regression analyses were performed at 95% confidence level. RESULTS: After adjusting for gender, perceived academic pressure, unhealthy behaviors, use of Internet devices, school bullying, and family living situation, a significantly higher risk of self-harm was detected among those who had experienced cyberbullying (adjusted odd ratio [AOR] = 2.97; 95% CI, 1.32-6.71). Parental acceptance retained a significant association with self-harm and suicidal behavior (P < 0.05) while parental concentration did not exhibit a significant association in a multivariable logistic regression model. In addition, suicidal ideation and suicidal planning were associated with an interaction effect between cyberbullying and parental concentration (AOR = 0.37; 95% CI, 0.15-0.94 and AOR = 0.23; 95% CI, 0.06-0.87, respectively). CONCLUSION: Cyberbullying has become an important phenomenon associated with self-harm among young adolescents in developing countries, and parental acceptance in proxy of parental attitude was positively related with severe mental health issues among adolescents. Thus, sufficient attention in efforts to promote adolescent health should be focused on family factors in the digital era of developing countries.

RESUMEN

The genus Ukamenia Oku (1981) was proposed with Simaethis sapporensis Matsumura (1931) from Japan as its type species, which had been originally described in the family Choreutidae. Oku (1981) based the new genus on characters of S. sapporensis that were typical of Tortricidae rather than Choreutidae, notably the naked haustellum (scaled in Choreutidae), among many other characters differing between the two families, such as wing venation, head morphology, and genital form. Oku (1981) assigned his new genus to the tribe Olethreu-tini, but mentioned that it resembled the genus Gatesclarkeana Diakonoff, 1966. In her extensive study of Australian Olethreutinae, Horak (2006) briefly noted Ukamenia as being referable to Gateclark-eanini.

RESUMEN

A new species of the synaphobranchid genus Atractodenchelys is described based on 31 specimens collected off Quy Nhon and Nha Trang, southern Vietnam. The new species can be distinguished from the only two congeners in the genus by having much fewer total vertebrae (155‒158, vs. 168‒172 in A. phrix and 186‒199 in A. robinsorum), a relatively long head (head length 10.1‒12.3% TL), a relatively short snout (30.0‒35.8% HL), head longer than trunk length (vs. about equal in length in both species); and 5‒6 compound teeth on vomer (vs. 7‒8 in A. robinsorum).

RESUMEN

A new species of Toleria Walker, [1865], T. aritai Ogane Kallies spec. nov., is described from Vietnam and Laos. Superficially, it resembles species of the genus Dasysphecia Hampson, 1919 but differs by venation and genitalia characters. The tribe Cissuvorini is briefly reviewed. Chimaerosphecia Strand, [1916] syn. rev. is considered a younger subjective synonym of Toleria. The following new combinations are introduced: Toleria aegerides (Strand, [1916]) comb. nov., Toleria colochelyna (Bryk, 1947) comb. nov., Toleria sinensis (Walker, [1865]) comb. rev. and Glossosphecia sinensis (Wang Yang, 2002) comb. nov.

RESUMEN

A new species of Megophrys is described from Cao Bang Province, northeastern Vietnam based on morphological and molecular data. Morphologically, the new species is distinguishable from its congeners by a combination of the following characters: Size small (SVL 34.9-38.9 mm in males); tympanum visible; vomerine teeth absent; tongue not notched posteriorly; male with a single vocal sac; toes with rudimentary webbing; subarticular tubercles and lateral fringes absent on all digits; nuptial pads present on fingers I and II in males, with spicules; dorsal skin with scattered granules and tubercles; flank with tubercles; dorsum with a X-shaped dorsal ridge; dorsolateral folds prominent; a small horn-like tubercle present at the outer edge of the eyelid; dorsal surface yellowish brown with a dark brown triangle between the eyes, and a dark brown marking along the X-shaped ridge on the back. In the phylogenetic analyses, the new species is unambiguously nested within the subgenus Panophrys with interspecific uncorrected genetic p-distances (16S rRNA gene) varying from 4.26% (compared with M. rubrimera) to 10.80% (compared with M. acuta).

RESUMEN

There has been no previous report detailing the taxonomy of marine bryozoans along the coasts of Vietnam. Here we report on the taxonomy and diversity of bryozoans collected among drift coral cobbles from a beach in the tropical Co To archipelago, Gulf of Tonkin, northern Vietnam. We detected 27 bryozoan species (23 cheilostomes, four cyclostomes) in a coelobite assemblage inhabiting crevices in the cobbles, and holes made by boring molluscs. The degree of bryozoan preservation varied greatly, suggesting that the cobbles had accumulated on the beach over a period of months to years, or even decades. Coral reefs in the Co To archipelago underwent a catastrophic decline in 2003-2008, and it is unclear whether the bryozoan assemblage reflects past diversity, present diversity remaining in the coral rubble, or both. We describe six new species: Parasmittina acondylata n. sp., Metroperiella cotoensis n. sp., Microporella tonkinensis n. sp., Rhynchozoon setiavicularium n. sp., R. latiavicularium n. sp., and Disporella phaohoa n. sp. All but two of the previously described species were already known from the Central Indo-Pacific coastal biogeographical realm of Spalding et al. (2007), which includes Vietnam. We report the third Recent record of the thalamoporellid Dibunostoma reversum (Harmer, 1926), which is quite similar to and might be conspecific with the lower Miocene species Thalamoporella transversa Guha Krishna, 2004; while it is premature to synonymize the two, we transfer T. transversa to Dibunostoma, as D. transversum. The calcareous, sheet-like, encrusting foraminiferan Planorbulina larvata was prominent in the coelobite assemblage and was often observed in substrate competition with bryozoans. A limited analysis of competitive interactions indicated that the encrusting bryozoans in the coelobite assemblage encountered P. larvata more often than they encountered other bryozoans, and that P. larvata out-competed bryozoans for substrate, reinforcing a growing sense of the importance of encrusting foraminifera in tropical and subtropical hard-substrate communities.

RESUMEN

Two nematode species isolated from sediments of the littoral zone of the South China Sea on the coast of Vietnam are described and illustrated. Microlaimus capitatus sp. n. is closely related to M. affinis Gerlach, 1958 and M. amphidius Kamran et al., 2009, but differs by having a thin, poorly developed pharyngostom, more posterior vulva and presence of terminal setae on the tail. The female of Dichromadora simplex Timm, 1961 is described and illustrated for the first time.

RESUMEN

We describe a new multidrug resistant Chitinophaga species that was isolated from patients with type 2 diabetes in Vietnam. Strain BD 01T was cultivated in 2017 from a blood sample of a patient suffering from bacteremia. Strain VP 7442 was isolated in 2018 from a pleural fluid sample of a patient who had presented with lung abscess and pleural effusion. Both strains are aerobic, Gram-negative, non-motile and non-spore-forming. The 16S rRNA gene sequences of both strains are 100 % similar and share a highest 16S sequence identity with Chitinophaga polysaccharea MRP-15T of 97.42 %. Their predominant fatty acid is iso-C15 : 0 (73.8 % for strain BD 01T and 79.8 % for strain VP 7442). The draft genome sizes of strains BD 01T and VP 7442 are 6 308 408 and 6 308 579 bp, respectively. They are resistant to beta-lactams, aminoglycosides, fluoroquinolones, metronidazole, fosfomycin, vancomycin and macrolides, and exhibit 20 and 18 antimicrobial resistance-related genes, respectively. Using the multiphasic taxonogenomic approach, we propose that strains BD 01T (=CSUR P9622=VTCC 70981) and VP 7442 (=CSUR P9623=VTCC 70982) represent a new species, for which we propose the name Chitinophaga vietnamensis sp. nov. Strain BD 01T was chosen as type strain of C. vietnamensis sp. nov.

RESUMEN

In line with information and communication technology (ICT) trends, nursing practice and its preparations are expected to change fundamentally over the coming decade. The Sustainable Development Goals (SDGs), issued by the United Nations, identify nurses as playing a significant role in achieving these goals and as using new technologies that will likely change how they deliver care to patients. Particularly for nursing care in developing countries, it is essential to emphasize the increased use and interoperability of electronic health records (EHR), mobile devices, big data analytics, and artificial intelligence. Four case studies, including the Malawi HIV system, community-based mobile APP in South Africa, the cloud base hospital information system (HIS) project in Marshall island, and smart hemodialysis in Vietnam, are examined in this article. In the near future, both information technology skills and interaction will have a significant impact on the nursing profession.

RESUMEN

The importance of faecal sludge management is gaining recognition. However, methods are still lacking to reasonably estimate the quantities and qualities (Q&Q) that need to be managed, which makes the planning for and implementing of management solutions quite difficult. The objective of this study was to collect and analyse Q&Q of faecal sludge at a citywide scale, and to evaluate whether "SPA-DET" data (=> spatially analysable - demographic, environmental and technical) could then be used as predictors of Q&Q of faecal sludge. 60 field samples and questionnaires from Hanoi and 180 from Kampala were analysed. Software tools were used in an iterative process to predict total solids (TS) and emptying frequency in both Hanoi, Vietnam and Kampala, Uganda. City-specific data could be predicted with types of "SPA-DET" data as input variables, and model performance was improved by analysing septic tanks and pit latrines separately. Individual models were built for TS concentrations and emptying frequency. In addition, a model was built across both cities for emptying frequency of septic tanks based on number of users and containment volume, indicating predictive models can be relevant for multiple cities. Number of users, containment volume, truck volume and income level were identified as the most common variables for the correction function. Results confirm the high intrinsic variability of faecal sludge characteristics, and illustrate the importance of moving beyond simple reporting of city-wide average values for estimations of Q&Q. The collected data and developed scripts have been made available for replication in future studies.

RESUMEN

To examine the willingness to pay (WTP) for a quality-adjusted life year (QALY) gained among advanced non-small cell lung cancer (NSCLC) patients in Viet Nam and to analyze the factors affecting an individual's WTP.A cross-sectional, contingent valuation study was conducted among 400 NSCLC patients across 6 national hospitals in Viet Nam. Self-reported information was recorded from patients regarding their socio-demographic status, EQ-5D (EuroQol-5 dimensions) utility, EQ-5D vas, and WTP for 1 QALY gained. To explore the factors related to the WTP, Gamma Generalized Linear Model and multiple logistic regression tools were applied to analyze data.The overall mean and median of WTP/QALY among the NSCLC patients were USD $11,301 and USD $8002, respectively. Strong association was recorded between WTP/QALY amount and the patient's education, economic status, comorbidity status, and health utility.Government and policymakers should consider providing financial supports to disadvantaged groups to improve their access to life saving cancer treatment.

RESUMEN

BACKGROUND: Tuberculosis (TB) is a major global health burden, with an estimated quarter of the world's population being infected. The World Health Organization (WHO) launched the "End TB Strategy" in 2014 emphasising knowing the epidemic. WHO ranks Vietnam 12th in the world of high burden countries. TB spatial and temporal patterns have been observed globally with evidence of Vitamin D playing a role in seasonality. We explored the presence of temporal and spatial clustering of TB in Vietnam and their determinants to aid public health measures. METHODS: Data were collected by the National TB program of Vietnam from 2010 to 2015 and linked to the following datasets: socio-demographic characteristics; climatic variables; influenza-like-illness (ILI) incidence; geospatial data. The TB dataset was aggregated by province and quarter. Descriptive time series analyses using LOESS regression were completed per province to determine seasonality and trend. Harmonic regression was used to determine the amplitude of seasonality by province. A mixed-effect linear model was used with province and year as random effects and all other variables as fixed effects. RESULTS: There were 610,676 cases of TB notified between 2010 and 2015 in Vietnam. Heat maps of TB incidence per quarter per province showed substantial temporal and geospatial variation. Time series analysis demonstrated seasonality throughout the country, with peaks in spring/summer and troughs in autumn/winter. Incidence was consistently higher in the south, the three provinces with the highest incidence per 100,000 population were Tay Ninh, An Giang and Ho Chi Minh City. However, relative seasonal amplitude was more pronounced in the north. Mixed-effect linear model confirmed that TB incidence was associated with time and latitude. Of the demographic, socio-economic and health related variables, population density, percentage of those under 15 years of age, and HIV infection prevalence per province were associated with TB incidence. Of the climate variables, absolute humidity, average temperature and sunlight were associated with TB incidence. CONCLUSION: Preventative public health measures should be focused in the south of Viet Nam where incidence is highest. Vitamin D is unlikely to be a strong driver of seasonality but supplementation may play a role in a package of interventions.

RESUMEN

Enterovirus-A71 (EV-A71) cyclically causes hand-foot-mouth disease (HFMD) epidemics in Asian children. An EV-A71 epidemic occurred in Southern Vietnam in 2011, but its scale is not clear. We collected residual sera from non-HFMD Vietnamese inpatients in 2012-2013 to determine seroprevalence of EV-A71 neutralizing antibodies, and measured cross-reactive neutralizing antibody titers against three EV-A71 genogroups. About 23.5% of 1-year-old children in Southern Vietnam has been infected by EV-A71, and the median age of infection was estimated to be 3 years. No significant antigenic variation could be detected among the three EV-A71 genogroups. The high seroprevalence of EV-A71 neutralizing antibody in children living in southern Vietnam indicates the necessity of introducing EV-A71 vaccines in southern Vietnam, particularly for children under 6 months of age. Moreover, it is critical to understand EV-A71 disease burden for formulating national vaccination policy.

RESUMEN

BACKGROUND: Joubert syndrome is a genetically heterogeneous autosomal recessive ciliopathy characterized by the combination of hypoplasia/aplasia of the cerebellar vermis, thickened and elongated superior cerebellar peduncles and a deep interpeduncular fossa, known as "molar tooth sign" associated with hypotonia, respiratory control disturbances and abnormal eye movements. To date, pathogenic variants in over 35 genes are known to cause autosomal recessive Joubert Syndrome, while one gene is associated with X-linked recessive inheritance. CASE PRESENTATION: We describe here a non-consanguineous Vietnamese family with Joubert syndrome, a fetus and 10-year-old developmentally delayed boy. Ultrasonography showed ventriculomegaly at 26 + 6 weeks of gestation in the fetus. The 10-year-old-boy was diagnosed with cerebral palsy of unknown origin. Clinical physical examination at the age of 10, he showed clinical features of Joubert syndrome including typical facial dysmorphism, ataxia, severe psychomotor delay, oculomotor apraxia and molar tooth sign on brain MRI. Whole exome sequencing analysis identified a novel compound heterozygous c.725A > G p.Asn242Ser and c.313-3 T > G p.Lys105Valfs*16 TMEM67 variant in the proband and the affected fetus. These two variants were inherited from each parent and confirmed by Sanger sequencing. The variant c.725A > G p.Asn242Ser was previously documented in patients with JS, the novel splice-site c.313-3 T > G p.Lys105Valfs*16 TMEM67 variant produced an aberrant transcript with the loss of four nucleotides of exon 03. CONCLUSION: This study confirms the diagnosis of Joubert syndrome in a Vietnamese family and expands the mutational spectrum of TMEM67 sequence variations. We also highlight the importance of molecular approaches to unravel underlying mechanisms of human genetic disorders. Early precise diagnosis could help provide further accurate genetic counseling for recurrence-risk assessment, future diagnostic option, management as well as treatment guidance for rare disorders.
