Vietnam’s political economy: a discussion on the 1986-2016 period

Being a member of the thriving ASEAN and successfully implementing economic renovation (Doi Moi) have drawn the world's attention on Vietnam around the turn of the millennium. Some even expected a much faster pace of transformation, and renewed economic, AND political, reforms in Vietnam, or Doi Moi II.However, in the recent transition turmoil the Vietnamese economy has experienced some significant setback, and the solution for getting the country out of the downward spiral of low productivity, waning purchasing power and increasing costs of doing business cannot be worked out without addressing those political economy issues that have shaped the modus operandi of the nation's economic system. This article discusses the post-Doi Moi political economy in Vietnam, from 1986 to 2016 – when the 12th Congress of the Communist Party of Vietnam takes place – and prospects of reviving reform momentum in subsequent years.

Humoral and B-cell memory responses in children five years after pertussis acellular vaccine priming.

The resurgence of pertussis suggests the need for greater efforts in understanding the long-lasting protective responses induced by vaccination. In this paper we dissect the persistence of humoral and B-cell memory responses induced by primary vaccination with two different acellular pertussis (aP) vaccines, hexavalent Hexavac(®) vaccine (Hexavac) (Sanofi Pasteur MSD) and Infanrix hexa(®) (Infanrix) (GlaxoSmithKline Biologicals). We evaluated the specific immune responses in the two groups of children, 5 years after primary vaccination by measuring the persistence of IgG and antibody secreting cells (ASC) specific for vaccine antigens. Part of the enrolled children received only primary vaccination, while others had the pre-school boost dose. A similar level of antigen-specific IgG and ASC was found in Infanrix and Hexavac vaccinated children. The mean IgG levels were significantly higher in children that received the pre-school boost as compared with children that did not receive the boost dose. A longer persistence after the pre-school boost of IgG-Pertussis Toxin (PT) and IgG-pertactin levels was observed in Infanrix primed children, but it was not statistically significant. More than 80% of children presented a positive ASC B memory response. Around 50% of children still presented protective IgG-PT levels which are reduced to 36% in no-boosted children. The pre-school booster dose restores the percentage of protected children above 50%. In conclusion our data underline the importance of giving a booster dose 5 years after primary vaccination and suggest the need for a new vaccine able to induce a long lasting protective response.

Adjuvant portal-vein infusion of fluorouracil and heparin in colorectal cancer: A randomised trial

Background. There is conflicting evidence on the efficacy of regional adjuvant chemotherapy, via portal-vein infusion (PVI), after resection of colorectal cancer. We undertook a randomised controlled multicentre trial to investigate the efficacy of PVI (500 mg/m2 fluorouracil plus 5000 IU heparin daily for 7 days). Methods. 1235 of about 1500 potentially eligible patients were randomly assigned surgery plus PVI or surgery alone (control). The patients were followed up for a median of 63 months, with yearly screening for recurrent disease. The primary endpoint was survival; analyses were by intention to treat. Findings. 619 patients in the control group and 616 in the PVI group met eligibility criteria. 164 (26%) control-group patients and 173 (28%) PVI-group patients died. 5-year survival did not differ significantly between the groups (73 vs 72%; 95% CI for difference -6 to 4). The control and PVI groups were also similar in terms of disease-free survival at 5 years (67 vs 65%) and the number of patients with liver metastases (79 vs 77%). Interpretation. PVI of fluorouracil, at a dose of 500 mg/m2 for 7 days, cannot be recommended as the sole adjuvant treatment for high-risk colorectal cancer after complete surgical excision. However, these results cannot eliminate a small benefit when PVI is used at a higher dosage or in combination with mitomycin.

Guidelines on artificial nutrition versus hydration in terminal cancer patients

Whether a terminally ill cancer patient should be actively fed or simply hydrated through subcutaneous or intravenous infusion of isotonic fluids is a matter of ongoing controversy among clinicians involved in the care of these patients. Under the auspices of the European Association for Palliative Care, a committee of experts developed guidelines to help clinicians make a reasonable decision on what type of nutritional support should be provided on a case-by-case basis. It was acknowledged that part of the controversy related to the definition of the terminal cancer patient, since this is a heterogeneous group of patients with different needs, expectations, and potential for a medical intervention. A major difficulty is the prediction of life expectancy and the patient's likely response to vigorous nutritional support. In an attempt to reach a decision on the type of treatment support (artificial nutrition vs. hydration) which would best meet the needs and expectations of the patient, we propose a three-step process: Step I: define the eight key elements necessary to reach a decision: Step II: make the decision; and Step III: reevaluate the patient and the proposed treatment at specified intervals. Step I involves assessing the patient concerning the following: 1) oncological/clinical condition; 2) symptoms; 3) expected length of survival; 4) hydration and nutritional status; 5) spontaneous or voluntary nutrient intake; 6) psychological profile; 7) gut function and potential route of administration; and 8) need for special services based on type of nutritional support prescribed. Step II involves the overall assessment of pros and cons, based on information determined in Step I, in order to reach an appropriate decision based on a well-defined end point (i.e. improvement of quality of life; maintaining patient survival; attaining rehydration). Step III involves the periodic reevaluation of the decision made in Step II based on the proposed goal and the attained result.

Human E2F6 is alternatively spliced to generate multiple protein isoforms

E2F6 protein belongs to the family of the E2F transcription factors. Here, we showed that the human E2F6 gene contains nine exons distributed along 20.4kbp of genomic DNA on chromosome 2 leading to the transcription of six alternatively spliced E2F6 mRNAs that encode four different E2F6 proteins. Moreover, we identified an E2F6 pseudogene localized on chromosome 22 completely spliced and devoid of exons 2, 3, and 4, and part of exons 1 and 5. Definition of the transcriptional initiation site and sequence analysis show that the gene contains a TATA less, CAAT less, GC-rich promoter with multiple transcription start sites. Regulatory elements necessary for basal transcription reside within a 134bp fragment as determined by transient transfection experiments. © 2004 Elsevier Inc. All rights reserved.

The Ets transcription factors of the PEA3 group: Transcriptional regulators in metastasis

The PEA3 group is composed of three highly conserved Ets transcription factors: Erm, Er81, and Pea3. These proteins regulate transcription of multiple genes, and their transactivating potential is affected by post-translational modifications. Among their target genes are several matrix metalloproteases (MMPs), which are enzymes degrading the extracellular matrix during normal remodelling events and cancer metastasis. In fact, PEA3-group genes are often over-expressed in different types of cancers that also over-express these MMPs and display a disseminating phenotype. Experimental regulation of the synthesis of PEA3 group members influences the metastatic process. This suggests that these factors play a key role in metastasis. © 2006 Elsevier B.V.

Pneumococcal aetiology and serotype distribution in paediatric community-acquired pneumonia.

Community-acquired pneumonia (CAP) is a major cause of morbidity in children. This study estimated the proportion of children with pneumococcal CAP among children hospitalised with CAP in Belgium and describes the causative serotype distribution after implementation of the 7-valent pneumococcal conjugate vaccine. Children 0-14 years hospitalised with X-ray-confirmed CAP were prospectively enrolled in a multicentre observational study. Acute and convalescent blood samples were collected. Pneumococcal aetiology was assessed by conventional methods (blood or pleural fluid cultures with Quellung reaction capsular typing or polymerase chain reaction [PCR] in pleural fluid), and recently developed methods (real-time PCR in blood and World Health Organization-validated serotype-specific serology). A total of 561 children were enrolled. Pneumococcal aetiology was assessed by conventional methods in 539, serology in 171, and real-time PCR in blood in 154. Pneumococcal aetiology was identified in 12.2% (66/539) of the children by conventional methods alone but in 73.9% by the combination of conventional and recently developed methods. The pneumococcal detection rate adjusted for the whole study population was 61.7%. Serotypes 1 (42.3%), 5 (16.0%), and 7F(7A) (12.8%) were predominant. In conclusion, Streptococcus pneumoniae remains the predominant bacteria in children hospitalised for CAP in Belgium after implementation of 7-valent pneumococcal conjugate vaccine, with non-vaccine-serotypes accounting for the majority of cases. The use of recently developed methods improves diagnosis of pneumococcal aetiology.

Operational scales, sources of finance, and firms’ performance: evidence from Vietnamese longitudinal data

This study investigates a longitudinal dataset consisting of financial and operational data from 37 listed companies listed on Vietnamese stock market, covering the period 2004-13. By performing three main types of regression analysis - pooled OLS, fixed-effect and random-effect regressions - the investigation finds mixed results on the relationships between operational scales, sources of finance and firms' performance, depending on the choice of analytical model and use of independent/dependent variables. In most situation, fixed-effect models appear to be preferable, providing for reasonably consistent results. Toward the end, the paper offers some further explanation about the obtained insights, which reflect the nature of a business environment of a transition economy and an emerging market.

Effect of cytochalasin B on 3-O-[(14)C]-methyl-D-glucose or D-[U-(14)C]glucose handling by BRIN-BD11 cells.

The present study aimed to investigate the effects of cytochalasin B (20 μM) on the uptake of 3-O-[(14)C]-methyl-D-glucose or D-[U-(14)C]glucose (8.3 mM each) by BRIN-BD11 cells. Taking into account the distribution space of tritiated water ((3)HOH), which was unexpectedly increased shortly after exposure of the cells to cytochalasin B and then progressively returned to its control values, and that of L-[1-(14)C]glucose, used as an extracellular marker, it was demonstrated that cytochalasin B caused a modest, but significant inhibition of the uptake of D-glucose and its non-metabolized analog by the BRIN-BD11 cells. These findings resemble those observed in acinar or ductal cells of the rat submaxillary gland and displayed a relative magnitude comparable to that found for the inhibition of D-glucose metabolism by cytochalasin B in purified pancreatic islet B cells. These findings reinforce the view that the primary site of action of cytochalasin B is located at the level of the plasma membrane.

"L'Invitation au voyage" de Baudelaire :une analyse évocative

This paper presents a detailed analysis of Baudelaire's poem ''L'Invitation au voyage''. It aims to understand the general meaning of this poem, showing that Baudelaire's ''voyage'' comes less to an ideal paradise than to a kind of voluptuous purgatory. We associate together dimensions of the poem that are usually treated separately :biographical background, stylistic and intertextual borrowings (orientalized Holland, Goethe's Mignon, popular song and romance, Weber's music, Biblical episodes), formal structure and cognitive effects. Our method is based on Benoît de Cornulier's theory of metrics, Searle and Vanderveken's speech act theory and Marc Dominicy's theory of poetic evocation. As Dominicy's theory is quite recent, our article provides substantial summary and clarification of its main theoretical and methodological hypothesis.

The Harsh Reality of Pursuing Innovations: Emerging Market Perspectives

This short conference paper serves as a distillation of a keynote address delivered at the the Second National Conference on Management and Higher Education Trends & Strategies for Management & Administration hosted by Bangkok-based Stamford International University (Thailand) on November 1, 2014.Innovation is discussed as the heart of entrepreneurial processes occurring in today's capitalist economic systems, including transition economies like China and Vietnam, which underscores economic competitiveness of firms and economies. But the innovation effort and process also face dilemma of "entrepreneurial curse of innovation". Advantages and disadvantages are weighed for a more balanced view, especially in the context of outnumbering SMEs and given existence of pitfalls and traps along the innovation path of development. Toward the end, the value of the market is once again stressed amid the concern of subjective assumption and illusion about availability of market opportunities in the mind of innovators, which may contrast totally with the dismal outcome the actual market realities may show ex post.

Incidence of febrile neutropenia and neutropenic infections in elderly patients receiving anthracycline-based chemotherapy for breast cancer without primary prophylaxis with colony-stimulating factors

There is concern about the potential increase of hematological toxicity in elderly patients treated with chemotherapy. Recently, primary prophylaxis with colony-stimulating factors (CSFs) was proposed for elderly patients receiving moderately toxic chemotherapy. However, evidence for the benefits of this primary prophylaxis for elderly breast cancer patients is currently lacking. We retrospectively analyzed the incidence of febrile neutropenia (FN) and neutropenic infections in elderly breast cancer patients receiving anthracycline-based chemotherapy without primary prophylaxis with colony-stimulating factors. In addition, we assessed the direct costs of hospitalization for these complications. Febrile neutropenia or neutropenic infection occurred in 13% of the 46 patients. Further studies are needed to adequately evaluate the risk of neutropenic complications (NC) in elderly patients receiving standard-dose chemotherapy for breast cancer and the potential benefits of primary prophylaxis with colony-stimulating factors. © 2004 Elsevier Ireland Ltd.

CB1 cannabinoid receptor deficiency promotes cardiac remodeling induced by pressure overload in mice

Background: The endocannabinoid system is known to play a role in regulating myocardial contractility, but the influence of cannabinoid receptor 1 (CB1) deficiency on chronic heart failure (CHF) remains unclear. In this study we attempted to investigate the effect of CB1 deficiency on CHF induced by pressure overload and the possible mechanisms involved. Methods and results: A CHF model was created by transverse aortic constriction (TAC) in both CB1 knockout mice and wild-type mice. CB1 knockout mice showed a marked increase of mortality due to CHF from 4 to 8 weeks after TAC (p = 0.021). Five weeks after TAC, in contrast to wild-type mice, CB1 knockout mice had a higher left ventricular (LV) end-diastolic pressure, lower rate of LV pressure change (± dp/dt max), lower LV contractility index, and a larger heart weight to body weight ratio and lung weight to body weight ratio compared with wild-type mice (all p < 0.05-0.001). Phosphorylation of the epidermal growth factor receptor (EGFR) and mitogen-activated protein kinases (P38 and ERK) was higher in CB1 knockout mice than that in wild-type mice. In cultured neonatal rat cardiomyocytes, a CB1 agonist reduced cAMP production stimulated by isoproterenol or forskolin, and suppressed phosphorylation of the EGFR, P38, and ERK, while the inhibitory effect of a CB1 agonist on EGFR phosphorylation was abrogated by CB1 knockdown. Conclusion: These findings indicate that cannabinoid receptor 1 inactivation promotes cardiac remodeling by enhancing the activity of the epidermal growth factor receptor and mitogen-activated protein kinases. © 2012 Elsevier Ireland Ltd.

Evaluation of the quality of the management of cancer of the corpus uteri-Selection of relevant quality indicators and implementation in Belgium

Objective Describe the methodology and selection of quality indicators (QI) to be implemented in the EFFECT (EFFectiveness of Endometrial Cancer Treatment) project. EFFECT aims to monitor the variability in Quality of Care (QoC) of uterine cancer in Belgium, to compare the effectiveness of different treatment strategies to improve the QoC and to check the internal validity of the QI to validate the impact of process indicators on outcome. Methods A QI list was retrieved from literature, recent guidelines and QI databases. The Belgian Healthcare Knowledge Center methodology was used for the selection process and involved an expert's panel rating the QI on 4 criteria. The resulting scores and further discussion resulted in a final QI list. An online EFFECT module was developed by the Belgian Cancer Registry including the list of variables required for measuring the QI. Three test phases were performed to evaluate the relevance, feasibility and understanding of the variables and to test the compatibility of the dataset. Results 138 QI were considered for further discussion and 82 QI were eligible for rating. Based on the rating scores and consensus among the expert's panel, 41 QI were considered measurable and relevant. Testing of the data collection enabled optimization of the content and the user-friendliness of the dataset and online module. Conclusions This first Belgian initiative for monitoring the QoC of uterine cancer indicates that the previously used QI selection methodology is reproducible for uterine cancer. The QI list could be applied by other research groups for comparison. © 2013 Elsevier Inc.
