Neonatal care practices in sub-Saharan Africa: a systematic review of quantitative and qualitative data.

BACKGROUND: Recommended immediate newborn care practices include thermal care (immediate drying and wrapping, skin-to-skin contact after delivery, delayed bathing), hygienic cord care and early initiation of breastfeeding. This paper systematically reviews quantitative and qualitative data from sub-Saharan Africa on the prevalence of key immediate newborn care practices and the factors that influence them. METHODS: Studies were identified by searching relevant databases and websites, contacting national and international academics and implementers and hand-searching reference lists of included articles. English-language published and unpublished literature reporting primary data from sub-Saharan Africa (published between January 2001 and May 2014) were included if it met the quality criteria. Quantitative prevalence data were extracted and summarized. Qualitative data were synthesized through thematic analysis, with deductive coding used to identify emergent themes within each care practice. A framework approach was used to identify prominent and divergent themes. RESULTS: Forty-two studies were included as well as DHS data - only available for early breastfeeding practices from 33 countries. Results found variation in the prevalence of immediate newborn care practices between countries, with the exception of skin-to-skin contact after delivery which was universally low. The importance of keeping newborn babies warm was well recognized, although thermal care practices were sub-optimal. Similar factors influenced practices across countries, including delayed drying and wrapping because the birth attendant focused on the mother; bathing newborns soon after delivery to remove the dirt and blood; negative beliefs about the vernix; applying substances to the cord to make it drop off quickly; and delayed breastfeeding because of a perception of a lack of milk or because the baby needs to sleep after delivery or does not showing signs of hunger. CONCLUSION: The majority of studies included in this review came from five countries (Ethiopia, Ghana, Malawi, Tanzania and Uganda). There is a need for more research from a wider geographical area, more research on newborn care practices at health facilities and standardization in measuring newborn care practices. The findings of this study could inform behaviour change interventions to improve the uptake of immediate newborn care practices

Effect of average litter weight in pigs on growth performance, carcass characteristics and meat quality of the offspring as depending on birth weight

Offspring born from normal litter size (10 to 15 piglets) but classified as having lower than average birth weight (average of the sow herd used: 1.46 ± 0.2 kg; mean ± s.d.) carry at birth negative phenotypic traits normally associated with intrauterine growth restriction, such as brain-sparing and impaired myofiber hyperplasia. The objective of the study was to assess long-term effects of intrauterine crowding by comparing postnatal performance, carcass characteristics and pork quality of offspring born from litters with higher (>1.7 kg) or lower ( 0.05). These pigs were fattened in group pen and slaughtered at 165 days of age. Pre-weaning performance of the litters and growth performance, carcass and meat quality traits of the selected pigs were assessed. Number of stillborn and pig mortality were greater (P 0.05) slaughter weight at 165 days of age. However, HL-gilts were more feed efficient and had leaner carcasses than HI-, LH- and LI-pigs (birth weight class × gender interaction P < 0.05). Meat quality traits were mostly similar between groups. The marked between-litter birth weight variation observed in normal size litters had therefore no evident negative impact on growth potential and quality of pigs from the lower birth weight grou

The presence of coconut in southern Panama in pre-Columbian times: Clearing up the confusion

Background The pre-Columbian presence of coconut on the Pacific coast of Panama is attested by a number of independent written accounts. However, recent papers question their accuracy and conclude that coconut was introduced to the region by the Spaniards after their conquests. Scope In order to examine the value of such claims, an extensive search was conducted of the relevant historical accounts of coconut in America and in the Orient. Key Results The Spanish chronicler Oviedo (1478-1557) is found to have effectively used fruit and seed size to distinguish coconut from other palms. In addition, it is shown that he has been inaccurately faulted with incorrectly representing a cluster of coconuts. The original drawing, a cluster of a native Bactris, was in the marginalia and was only assigned to coconut after Oviedo's death. Finally, the location is identified of a coastal Panamanian site described by Pedro Mártir de Anglería and where tidal dispersal of coconuts was observed. Conclusions This previously overlooked evidence confirms the pre-historical presence of coconut in Panama. Genetic data indicate that it must have been brought there directly or indirectly from the Philippines. But when, where and by whom remains a subject of research. Further molecular marker studies, computer simulation of natural drift and archaeological research could contribute to this research. (Résumé d'auteur

Decreasing the level of hemicelluloses in sow’s lactation diet affects the milk composition and post-weaning performance of low birthweight piglets

Hemicelluloses (HC) are polysaccharides constituents of the cell walls of plants. They are fermented in the gut to produce volatile fatty acids (VFA). The present study investigated the effects of decreasing HC level in a sow’s lactation diet on sow performances, offspring development and milk composition. From 110 days (d) of gestation until weaning (26 ± 0.4 d post-farrowing), 40 Swiss Large White sows were assigned to one of the four dietary treatments: (1) T13 (HC: 127 g/kg), (2) T11 (HC: 114 g/kg), (3) T9 (HC: 94 g/kg) and (4) T8 (HC: 80 g/kg). Milk was collected at 3 and 17d of lactation. At birth, piglets were divided into two groups according to their birthweight (BtW): normal (N-BtW; BtW &gt;1.20 kg) or low (L-BtW; BtW ≤1.20 kg). Decreased HC levels in the maternal diet linearly increased (p ≤.05) the body weight of L-BtW piglets at two weeks post-weaning and linearly decreased (p ≤.05) diarrhoea incidence and duration in this category. The concentrations of copper, threonine and VFA, as well as the proportion of butyrate, in milk linearly increased (p ≤.05), whereas lactose content linearly decreased (p ≤.05) with decreased HC in the maternal diet. The present study provides evidence that decreasing HC level in a sow’s lactation diet can positively affect the composition and VFA profile of milk and ultimately favour the growth and health of L-BtW piglets.Highlights The results of this study showed that decreasing the level of hemicelluloses in a sow’s lactation diet modified milk composition and had positive effects on the post-weaning performance of low birthweight piglets. This study highlighted the role of dietary fibres in the maternal diet to alleviate body weight variations at two weeks post-weaning. Nevertheless, before advising pig producers, further research should elucidate the optimal level of hemicelluloses for lactating sows

Malaysia as a culinary tourism destination : international tourists’ perspective / M. Shahrim Ab. Karim, Bee-Lia Chua and Hamdin Salleh

This study was conducted to determine Malaysia’s current food image and food attribute satisfaction from international tourists’ points of view and subsequently assess their overall satisfaction with the eating experience and behavioral intention. The results indicated that Malaysia possesses clear images of ‘core food value’, ‘Malaysian food specialty’, and ‘Malaysian food uniqueness’ but is rather unclear on the images of ‘food and dining atmosphere’ and ‘features of Malaysian food’. Tourists’ satisfaction with ‘quality and value of food’ and ‘accessibility convenience’ were relatively higher than ‘dining atmosphere’ and ‘culinary tourism products’. Regression analyses revealed that food images and food attributes’ satisfaction significantly predicted tourists’ overall satisfaction, and the overall satisfaction revealed a significant relationship with tourists’ behavioral intentions. Implications for managers who are involved in food tourism are posited
