He examined 770 fishes (in 54 species) and recovered from them 42 species of copepod parasites. Twelve of these Kojima Bay parasites have already been treated elsewhere (Tran The Do, 1981; Tran The Do and Kasahara, 1982; Ho and Tran The Do, 1982; Tran The Do and Ho, in press; Ho, Tran The Do and Kasahara, in press). In this report, we shall deal with three species of the collected parasites that belong to the Family Lernaeopodidae. In the course of our study of these newly collected Japanese lernaeopodids, we felt the necessity of reexamining the specimens of Brachiella elegans Richiardi that were reported by Wilson (1915) from Woods Hole, Massachusetts. Unexpectedly, this reexamination of Wilson's material led us to establish a new genus, Eobrachiella, for accommodation of one of the three lernaeopodids from Kojima Bay. We have also discovered that the character states of Charopinopsis, which was erected by Yamaguti (1963) for accommodation of a spurious Charopinus species (C. quaterina Wilson, 1935), needed to be reconsidered. A discussion on this matter was made possible through a study of the collection of Charopinopsis quaterina (Wilson) that was made by one of us (JSH), off Key West, Florida. We adopt Kabata's (1979) terminology in the present treatment of the Japanese lernaeopodids, except for the posteriormost paired structures called "uropods." We disagree with Kabata in calling them "uropods", because we consider them not to be homologous to the malacostracan uropods, which are the last pair of the abdominal appendages located at the posteriormost part of the growth zone. Since the posteriormost paired structure~ in all modern copepods are carried by the anal somite, 'which is located posterior to the growth zone, they can not be treated as homologous to the uropods. Thus, we shall follow the traditional terminology and call this paired structures the caudal rami. The type specimen has been deposited in the United States National Museum of Natural History,

This creates uncertainty as to whether patients receiving the TC regimen should also receive granulocyte colony-stimulating factor primary prophylaxis (G-CSFpp), which is recommended when chemotherapy regimens have ≥20 % FN rate. We conducted a meta-analysis of published studies to determine FN rate with the TC regimen, its dependence on patients' age, and the efficacy of G-CSFpp in reducing it in ESBC patients. We systematically searched the literature via PUBMED using the following terms: 'docetaxel', 'cyclophosphamide', 'febrile neutropenia', and 'breast cancer'. Inclusion criteria were full text peer-reviewed clinical studies in English reporting FN rates with TC regimen in relationship to G-CSFpp. Comprehensive meta-analysis software was u...

The paper explores progress on REDD+ Readiness across four countries (Cameroon, Indonesia, Peru and Vietnam) and provides broad lessons, recommendations and examples across these countries for further improving REDD+. The paper also suggests an innovative, credible and universally applicable set of criteria and indicators derived through a systematic review that could serve further global comparative analysis of readiness for REDD+ and relevant national environmental services delivery systems, including climate change mitigation.

A multi-stage cluster-randomised sampling method was used to recruit 2872 children. Anthropometric measurements included weight, height, mid-upper arm circumference, and waist and hip circumferences. Blood biochemistry involved analyses of Hb, serum ferritin, and vitamins A and D. Dietary intake was assessed using a 24 h recall questionnaire, and nutrient intakes were compared with the Vietnamese RDA. In children aged < 5 years, approximately 14 % were stunted, 8·6 % underweight and 4·4 % thin. A higher prevalence of stunting (15·6 %) and underweight (22·2 %) was observed in school-aged children. Undernutrition was more prevalent in rural areas than in urban areas. In contrast, almost 29 % of the urban children were either overweight or obese when compared with 4 % of the overwei...

Totally , 299 people aged over 18 were involved in this study. Among them, 98 subjects were selected from one commune with low income, 100 and 101 subjects from two urban areas with medium and high income respectively. Food intake was assessed by 24-h recall method and lipid status was evaluated by measuring serum concentration of triglyceride, total choles terol and its subfractions. The results showed that food consumption, dietary habits and lipid status varied with income levels. In general, diet was still unbalanced in all three groups, and low in fat and protein. In the rural, fat and protein intakes were lower than in the urban. The high prevalence of low serum cholesterol was observed in all three groups, the highest in the rural (45.3%) and the lowest in the urban (11.2%). On the contrary, the prevalence of high serum cholesterol was the lowest in the rural (2%) and the highest in the urban (16%). From these data, it is suggested that the majority of the Vietnamese might be vulnerable to some vascular diseases such as stroke if the situation of low fat intake and low serum cholesterol is not a problem of concern.

The impact of spatial dimensions of neonatal survival has not been thoroughly investigated even though access to good quality delivery care is considered to be one of the main priorities when trying to reduce neonatal mortality. This study examined the association between distance from the mother's home to the closest health facility and neonatal mortality, and investigated the influence of distance on patterns of perinatal health care utilisation. Methods: A surveillance system of live births and neonatal deaths was set up in eight districts of Quang Ninh province, Vietnam, from July 2008 to December 2009. Case referent design including all neonatal deaths and randomly selected newborn referents from the same population. Interviews were performed with mothers of all subjects and GIS coordinates for mothers' homes and all health facilities in the study area were obtained. Straightline distances were calculated using ArcGIS software. Results: A total of 197 neonatal deaths and 11 708 births were registered and 686 referents selected. Health care utilisation prior to and at delivery varied with distance to the health facility. Mothers living farthest away (4 th and 5 th quintile, ≥1257 meters) from a health facility had an increased risk of neonatal mortality (OR 1.96, 95% CI 1.40-2.75, adjusted for maternal age at delivery and marital status). When stratified for socioeconomic factors there was an increased risk for neonatal mortality for mothers with low education and from poor households who lived farther away from a health facility. Mothers who delivered at home had more than twice as long to a health facility compared to mothers who delivered at a health care facility. There was no difference in age at death when comparing neonates born at home or health facility deliveries (p = 0.56). Conclusion: Distance to the closest health facility was negatively associated with neonatal mortality risk. Health care utilisation in the prenatal period could partly explain this risk elevation since there was a distance decay in health system usage prior to and at delivery. The geographical dimension must be taken into consideration when planning interventions for improved neonatal survival, especially when targeting socioeconomically disadvantaged groups.

The results showed the suburban and urban populations had higher fat intake than the rural. The fat intake in quality was different in these three populations. The suburban had the highest consumption of fatty foods rich in n-6 polyunsaturated fatty acid (PUFA). The rural consumed more fatty foods rich in monounsaturated fatty acid (MUFA), but less fatty foods rich in n-3 PUFA than the two other populations. The high index of thrombogenicity (IT) of the Vietnamese diet may result from their low intake of fish and vegetable oils. Risk factors for premature cardiovascular disease (CVD) assessed by serum lipoprotein(a) and apolipoprotein levels were not observed in all three populations. However, coronary heart disease (CHD) and stroke are problems that should be monitored because the increase of CVD morbidity has been reported in Vietnamese people. From a nutritional point of view, the increase of fish and vegetable oils consumption is necessary for the prevention of CVD and CHD in these Vietnamese populations.
