Appropriate feeding practices are important during infancy for good health, growth and development of infants and children. WHO revised its earlier recommendation of Exclusive Breastfeeding (EBF) of infants from 4 to 6 months of age to EBF until about 6 months of age, with the addition of complementary foods thereafter. This recommendation confirms that breast milk alone is sufficient to meet infants’ nutritional requirements for the first 6 months of life. The main objective of this study was to investigate the effect of various feeding practices on the Nutritional status of infants 0 - 12-month-old in the Kumba 1 Sub-Division. A descriptive cross-sectional study was conducted from December 2019 to August 2020. A total of 341 nursing mothers and their infants 0 - 12 months of age were recruited. Socio-demographic factors and the different feeding habits of the children were assessed using a semi-structured questionnaire. Nutritional status was assessed using anthropometric measurements. The overall proportion of infants who exclusively breastfed for 6 months was 69.2% and those who were mix-fed were 30.8% in the study area. The overall prevalence of malnutrition in the population was 61.0%. Among the malnourished children, 53.1% were underweight, 19.6% were wasted and 10.0% were stunted. Though not significant, the prevalence of wasting (21.0%) and underweight (58.3%) was higher among Mix-Fed (MF) children when compared to their EBF counterparts. Feeding practices affected the nutritional status of the infants. Underweight and wasting were observed among infants on Complementary Feeding (CF), although some exclusively breast-fed infants were stunted. Hence, nursing mothers should try as much as possible to practice EBF as recommended by WHO and can practice CF when the child is above six months. 展开更多

Background:Hypertrophic scars and keloids,common complications following median sternotomy for cardiac surgery,significantly impact patient quality of life due to their aesthetic and symptomatic burden.Recent advancements in laser therapy have made it a prominent option for managing these complex scars,yet a com-prehensive understanding of its efficacy is lacking.The aim of this scoping review is to explore the effects of laser therapy in managing hypertrophic scars and keloids after median sternotomy.Methods:This scoping review ana-lyzed studies up to February 2024 from databases including PubMed,EMBASE,CINAHL,Scopus,Web of Science,and the Cochrane Library.We included any study that assessed laser therapy’s effects on hypertrophic scars and keloids following median sternotomy.Studies were selected based on predefined inclusion criteria with-out publication year,design,or origin restrictions.Results:Six studies met the inclusion criteria,involving a total offive RCTs and one review.These studies primarily tested 585 and 595-nm pulsed dye laser(PDL)treatments,focusing on scar appearance,patient symptoms,and treatment satisfaction.Most studies reported significant improvements in scar height reduction and patient symptom relief after treatment,with mixed results for scar erythema and elasticity.Adverse events were generally mild and transient.Conclusions:Laser therapy offers a beneficial approach for improving the appearance and symptoms of hypertrophic scars and keloids post-median sternotomy.However,further research is necessary to optimize treatment parameters and explore the long-term psychosocial impacts of this therapy.This review highlights the need for more comprehensive studies to establish standardized treatment protocols and evaluate their effectiveness. 展开更多

However, the adaptation physiology between leeches and hosts is not fully understand. To disclose the molecular mechanisms of adaptation between leech and host, the body transcriptomes of hunger and fed blood-sucking Poecilobdella javanica, Haemadipsa cavatuses, and Hirudo nipponia leeches were obtained by RNA sequencing, after comparison, a stratified unigenes group was obtained, which closely correlated to body distension. In the group, Rfamide receptor decreased significantly (P < 0.05) while serotonin receptor increased significantly (P < 0.05). Moreover, four KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways, including cardiac muscle contraction, complement and coagulation cascades, renin-angiotensin system, and hypertrophic cardiomyopathy were significantly enriched. The unigenes annotation, neuroregulators correlation analysis and induced function of the KEGG pathways, were consistently supported the same result as: vasoconstriction and systole reaction enhance in hunger leeches and vice versa vasodilation and diastole increase in fed leeches, meanwhile, Interspecific comparison and correlative analyses of physiological function showed that the strongest reaction of induced heart failure from four KEGG occur in strongest reaction of systole in hungry P. javanica and in strongest reaction of diastole in fed H. nipponia. Overall, heart failure is likely a physiological function involved in feeding behaviour. 展开更多

Although the effects of diet on intestinal microbiotas have been well investigated,the effect of feeding time on the rhythm of gut microbiota remains uncertain.A 9-week feeding trial on Pelteobagrus fulvidraco was conducted.Two triplicate groups of fish were fed identically either at 8:00(day)or at 20:00(night).After 9 weeks,three fish from each cage were sacrificed every 4 h for 24 h.The intestinal contents were analyzed using high-throughput sequencing.Three phyla(Fusobacteria,Proteobacteria,and Verrucomicrobia),and three genera(Cetobacterium,Akkermansia,and Clostridium)were dominant at every time point.Moreover,33.02%of detected amplicon sequence variants showed cyclical variations in fish fed at 20:00,and 3.47%in fish fed at 8:00.Among the top 20 genera,17 showed cyclical variations in the 20:00 group,and only two in the 8:00 group.Rhodobacter,Ralstonia,Mycobacterium,Lactococcus,Halomonas,Akkermansia,and Acinetobacter contributed more to the predicted functional pathways.Moreover,144 and 38 pathways exhibited daily cyclical fluctuations in fish fed at 20:00 and 8:00,respectively.Overall,certain intestinal microorganisms showed a circadian rhythm in P.fulvidraco,and this circadian rhythm was affected by shifted feeding times. 展开更多

Aim: Recently, the role of feeding coparenting has gained attention in the child eating research field. The Feeding Coparenting Scale (FCS), a measure of how caregivers interact with their partners when feeding their children was developed in the United States in 2019. However, there is no valid and reliable measure to assess feeding coparenting among caregivers of school-aged children in Japan. Therefore, this study aimed to develop a Japanese version of the FCS (FCS-J) questionnaire for caregivers with school-aged children. Methods: This was a web-based cross-sectional survey completed by caregivers of children aged 10-12 years. A preliminary survey using interviews and a web-based survey was conducted and found that the translated items of the FCS into Japanese were understandable to Japanese people. The developed survey was administered to parents of children at an elementary school. The reliability of the survey was assessed using both test-retest reliability and internal consistency analysis. Exploratory factor analysis was used to test construct validity, and known population validity was examined in relation to attributes, marital satisfaction, and feeding tasks. Results: Findings with 135 parents of school-aged children showed good internal reliability and validity of the FCS-J. The mean score for the overall FCS-J score was 46.2 (SD = 6.2), with Cronbach’s α of 0.72. For the subscales, Cronbach’s α ranged from 0.75 to 0.79. In sum, the present study’s results support the three-factor structure of the FCS in Japanese caregivers in Japan. Conclusions: The developed FCS-J was found to have a certain degree of reliability and validity. In this study, a Japanese version of the FCS-J was developed. . 展开更多

The aim of the study was to assess feeding practices and the use of lysine and methionine in pig rationing on intensified and semi-intensive pig breeding in the Koudougou and Bobo-Dioulasso areas. To this end, a cross-sectional survey was carried out on 87 breeding in these towns. A Discriminant Factorial Analysis (DFA) confirming a k-means classification of the data collected was used to retain 71 breeding divided into three breeding classes: Class A (32.4% of breeding), Class B (14.08%) and Class C (53.52%). The results show that the majority of pig breeders were men between the ages of 36 and 59. Average herd sizes were 35 ± 28;79 ± 42 and 89 ± 21 pigs for Classes A, B and C respectively. The main breeds of pig found on the breeding were crossbred, Large white, local, Landrace and Duroc. Class A (26.1%), B (30%) and C (15.8%) breeders were familiar with both lysine and methionine. Class A breeders distributed feed staggered (65.2%) and in rations (34.8%). Lysine (13%) and methionine (8.7%) were purchased at 5250 FCFA/kg. Those in class B distributed feed staggered (50%) and in the form of rations (50%), in which they incorporated lysine (30%) and methionine (30%) purchased at a cost of 2500 FCFA/kg and 3000 FCFA/kg respectively. Rationing and staggered feeding were practiced by 23.7% and 76.3% of Class C breeders respectively. Only lysine purchased at 3400 FCFA/kg was incorporated into rations by 10.5% of breeders. The high cost of lysine and methionine was incriminated by Class A (100%), B (33.3%) and C (50%) breeders. In conclusion, intensive pig breeding, the practice of rationing and the incorporation of the amino acids lysine and methionine are of ascending importance from classes C, A to B. The high cost of feedstuffs, particularly lysine and methionine, compromises their use in rations, which could have a negative impact on expected breeding performance. The screening and use of feeds rich in and/or enriched with these amino acids, through the development or adaptation of technologies, could improve the efficiency of rations and the productivity of intensive pig breeding in Burkina Faso. 展开更多

BACKGROUND Early initiation of enteral feeding is recognized to play a crucial role in improving the outcomes of treatment of acute pancreatitis.However,the method of adminis-tration of enteral nutrition remains debatable.We present the experience of treating a patient with moderate-severe acute pancreatitis,at high risk of progressing to a severe or fatal condition,using a novel method of selective feeding with duodenal isolation.CASE SUMMARY A 27-year-old female patient presented to the emergency unit of the hospital with a typical manifestation of acute pancreatitis.Despite a conventional treatment,the patient’s condition deteriorated by day 2 of hospitalization.Using an endoscopic approach,a novel catheter PandiCathffwas placed to the duodenum of the patient,isolating its segment between the duodenal bulb and the ligament of Treitz.In the isolated area created,a negative pressure was applied,followed by introduction of early selective enteral feeding.The patient’s condition subsequently improved in a rapid manner,and no complications often associated with moderate-to-severe acute pancreatitis developed.CONCLUSION Within 48 h of starting treatment with the novel method,it can prevent the development of multiple organ failure and,when combined with minimally invasive drainage methods,help prevent infection. 展开更多

Scars, when in good evolution, result in a smooth, thin and discreet tissue. Keloid scars, however, are a type of abnormal and exacerbated repair response to tissue injury, whether in surgical interventions or in various injuries, which present in a prominent and gross way. In this context, there is an excess of collagen deposition in the tissue repair process, which can lead to the formation of keloids. The diagnosis of the condition presented is made by the medical professional or by the patient himself after the surgical intervention or skin injury. Under this analysis, protruding, rough and bad-looking scars are identified. In addition, we highlight the existence of keloids similar to large tumors, described as Jorge Lobo disease. The treatment encompasses massages, compressions, corticosteroids, chemotherapy, collagenase and cryotherapy. At first, we used corticosteroid-based massages, and then we started using compressive dressings until we started intrakeloid infiltrations with injectable triamcinolone. Triamcinolone 10 mg injectable—1/10—in 0.9% saline, with syringe and fixed needle 0.3 mm × 8 mm, intralesional infiltrate, in this context, proved to be effective for its treatment when applied sequentially and linearly. In cases where the medication was applied, there was an improvement after 21 days of application and a definitive improvement 2 months after the injury. In comparison, on the other hand, patients who were not subjected to the application of the medication may improve after 4 months of the injury or worsen compared to the initial case. We have come to the conclusion that this procedure may be one of the chosen ones for the treatment of keloid scars, being one of the most recommended for cases of keloid already installed. 展开更多

Background:Given that the formation of eating behaviors in childhood is largely dependent on parental feeding,it is necessary to consider eating behaviors along with feeding behaviors when exploring child nutrition.Responsive feeding can not only promote the development of self-regulation ability,prevent overweight and obesity,and develop healthy dietary behaviors but also enhance the psychosocial ability,cognitive ability,and language ability of infants.it is of great significance for the growth and development of infants to identify whether the feeding behavior of caregivers is responsive feeding as early as possible.Methods:The progress of the literature summarizes the relevant concepts,evaluation tools,and the relationship between responsive feeding and dietary behavior.Results:This is a fact that China lacks the unified response feeding definition and responsive feeding evaluation tools suitable for homes in China.The relationship between responsive feeding and dietary behavior is in the stage of infancy,and systematic response feeding and dietary behavior have not been formed.Conclusion:It is time to pay attention to the dietary behavior of Chinese children.Intervening measures such as promoting the application of responsive feeding should be actively carry out,accordingly,childhood obesity can be prevented. 展开更多

Plants with bioactive properties are greatly useful in preventing and controlling blood-sucking and disease-vector invertebrates, particularly in developing countries and low-income communities. Their application is a promising alternative to synthetic compounds whose use remains a health, environmental, and economic challenge. However, many are still unknown and unvalued, while others are becoming ignored and threatened. The main objective of this ethnobotanical study is to identify and characterize indigenous and locally grown plants against blood-sucking and disease-vector insects. Salient opportunities and challenges of using these plants are documented and discussed. Semi-structured interviews, using a prepared questionnaire, were conducted with 228 informants. The consensus index (CI) was calculated to analyze the reliability of the collected information. The identified 31 anti-insect plant species belong to 20 botanical families, four morphological categories, and six habitat types. They can be categorized as insecticidal plants (42% of the total), insect repellent (42% of the total), and both insecticidal and insect repellent (16% of the total). More than 54% of these are still abundant in the study area, while about 35.5% have become rare and difficultly accessible. Based on the numerical importance of related anti-insect plant species, the seven targeted blood-sucking insects range in the following decreasing order: Jiggers (16 species) > Fire Ants (9 species) > Flies (8 plants) > Mosquitoes (4 species) > Fleas (2 species) > Bedbugs (1 species) > lice (0 species). The three most commonly used plants, with the highest confirmation indices, are Tetradenia riparia (ICs = 0.712), Eucalyptus globulus subsp. maidenii (ICs = 0.302), and Solanum aculeastrum (ICs = 0.288). The antimicrobial role of many locally grown anti-insect plants and the multiple other associated valorization possibilities are ignored by most informants. Domesticating, propagating, protecting, and promoting the sustainable use of these plants would be an appropriate route for their conservation and continued availability. 展开更多

为探讨脱氢表雄酮(Dehydroepiandrosterone,DHEA)对饲喂高脂饲料肉鸡脂质代谢、抗氧化和血管内皮功能的影响,将200只15日龄青脚麻鸡随机分为5组,其中对照组(CON)饲喂基础饲料,高脂饲料组(High Fat Diet,HFD)、DHEA低剂量干预组(HFD+D5)... 为探讨脱氢表雄酮(Dehydroepiandrosterone,DHEA)对饲喂高脂饲料肉鸡脂质代谢、抗氧化和血管内皮功能的影响,将200只15日龄青脚麻鸡随机分为5组,其中对照组(CON)饲喂基础饲料,高脂饲料组(High Fat Diet,HFD)、DHEA低剂量干预组(HFD+D5)、DHEA中剂量干预组(HFD+D15)、DHEA高剂量干预组(HFD+D45)分别饲喂添加0、5、15、45 mg/kg DHEA的高脂饲料。于试验第2、4周,测定肌间脂肪宽、皮下脂肪厚、皮脂质量、腹脂质量,计算腹脂率、皮脂率;采集血样检测激素和生化指标;采集肝脏组织检测抗氧化功能和肝脂酶(Hepatic Lipase,HL)活性。与对照组相比,高脂饲料显著增加肉鸡的腹脂质量、腹脂率、皮脂率及血液甘油三酯(Triglyceride,TG)、脂蛋白a(Lipoprotein a,LP(a))、血管紧张素Ⅱ(AngiotensimⅡ,AngⅡ)水平,但降低血清高密度脂蛋白(High Density Lipoprotein,HDL)、T_(3)、T_(4)、FT_(3)、FT_(4)和一氧化氮(NO)水平;同时,高脂饲料显著提高肝脏丙二醛(Malondiadehyde,MDA)含量,但降低肝脏(HL)、总超氧化物歧化酶(Superoxide Dismutase,SOD)和谷胱甘肽过氧化物酶(Glutathione Peroxidase,GSH-Px)活性。与HFD组相比,DHEA处理对饲喂高脂饲料肉鸡的体脂沉积及血清中TG、TC、LP(a)含量均有降低趋势;同时,DHEA能够升高血清T_(3)、T_(4)、FT_(3)、FT_(4)、NO水平及肝脏HL、SOD、GSH-Px活性,并降低肝脏MDA含量和血浆AngⅡ水平。补充DHEA对高脂饲料引发的肉鸡脂代谢紊乱、氧化应激和内皮功能障碍有一定缓解作用,其作用机理可能是通过调节血清甲状腺激素水平,增强肝脏HL活性,从而加速脂肪的分解,抑制脂肪沉积,继而减弱氧化应激,并改善血管内皮功能。 展开更多
