Methodology: This was a retrospective cohort study. HIV-infected children on ART aged less than 15 years were divided into two groups Group 1 (G1) comprising children who started ART prior 2 years and Group (G2) those put on treatment thereafter. Main Measures: Percentage of children with growth retardation measured by Height for Age (H/A) and Weight for Age (W/A) Results: In total, we included 90 subjects. The median age was 10 years with a slight female predominance (51.2%). Most children were asymptomatic at the time of the study (96.6%), compliant with treatment (81%), 54.8% of children were on cotrimoxazole, 33% knew their status. At initiation, underweight was predominant in group 1 compared to group 2 (52% versus 29.5%;p = 0.015). Conversely, stunted growth predominated in G2 compared to G1 but without significant difference (38% versus 50%;p = 0.147). At the time of our study (median age of 10 years), catch-up height and weight predominated in G1 compared to G2;only a small proportion remained below −2SD (4% versus 18.2%;p = 0.015 and 9% versus 29.5%;p = 0.006 respectively for underweight and stunted growth). Conclusion and Global Health Implications: Growth retardation was common at ART initiation. Catch-up in height was more evident in the early treatment group. Initiation of ART before the age of 2 years rather influences children’s height than weight. The result of this study further emphasizes the need of early ART and closed clinical monitoring to better assess the impact of ART in areas with high rates of undernutrition.展开更多

文摘This study investigated the effects of planting duration(1,5,10 and 15 years)on soil properties,bacterial community diversity,and function in the rhizosphere of Zanthoxylum bungeanum.We employed Illumina highthroughput sequencing and PICRUSt2 functional prediction to analyze the structure and functional potential of rhizosphere soil bacterial communities.The Mantel test and redundancy analysis were used to identify physicochemical factors influencing bacterial community structure and function.The results indicated significant differences in rhizosphere soil physicochemical properties across planting years:the content of organic matter,alkaline hydrolyzable nitrogen in the soil,as well as the activity of invertase,urease,and alkaline phosphatase initially increased and then decreased,while available potassium,Olsen-phosphorus content,and peroxidase activity continued to increase.However,bacterial alpha diversity(Chao1 and Shannon indices)and the number of amplicon sequence variants increased continuously with planting duration.Principal coordinate analysis and Adonis tests revealed that the planting year significantly influenced the bacterial community structure(p<0.05).The phyla Proteobacteria,Actinobacteria,Acidobacteriota and Chloroflexi collectively constituted 56.7%to 71.2%of the relative abundance,representing the dominant taxa.PICRUSt2 predictions indicated key functional categories(cellular processes,metabolism,genetic information processing,and environmental information processing)each exceeding 10%relative abundance.BugBase analysis revealed a progressive increase in aerobic and oxidative stress-tolerant bacteria and a decrease in anaerobic and potentially pathogenic bacteria.Differential indicator species analysis identified Firmicutes,Planctomycetes,Methylomirabilota and Actinobacteriota as key discriminators for the 1-,5-,10-and 15-year stages,respectively.Organic matter,alkaline phosphatase,soil pH,and available phosphorus were the primary physicochemical drivers of bacterial communities.Notably,soil organic matter significantly influenced both the community structure(p<0.05)and predictedmetabolic functions(p<0.05).In conclusion,prolonged planting duration significantly enhanced rhizosphere microbial diversity and functional gene abundance in Z.bungeanumwhile driving the structural succession of bacterial communities dominated by Proteobacteria,Actinobacteria,Acidobacteriota,and Chloroflexi.This ecological shift,characterized by increased aerobic/oxidative-stress taxa and decreased anaerobic/pathogenic bacteria,was primarily regulated by soil organic matter,a key driver shaping both community structure and metabolic functions,ultimately improving soil microecological health.

文摘This study analyzed case and prescription data of children aged 12 to 18 years diagnosed with influenza A from the outpatient and emergency departments at the Women and Children’s Hospital of Ningbo University during the influenza epidemic period between February and April 2023.Patients were categorized into two groups based on their medication:the Baloxavir Marboxil group(196 cases)and the Oseltamivir group(126 cases).SPSS Statistics 24.0 software was utilized to compare variables between the two groups,including age,sex,weight,first visit department,number of visits,average prescription cost per patient,drug varieties used,hospitalization rate,and the combined medication usage,to evaluate the relative advantages and disadvantages of the two treatments.The results indicated that the number of visits in the Baloxavir Marboxil group was significantly lower than in the Oseltamivir group,whereas the average prescription cost per patient was higher(P<0.05).There were no significant differences between the two groups regarding age,sex,weight,first visit department,number of drug types used,hospitalization rate,or combined medication usage(P>0.05).When comparing the use of single-class combined drugs,only the quantity of antiviral drugs differed significantly(P<0.05).The Oseltamivir group required more adjuvant treatment with both Chinese and Western antiviral medications.The distribution of the number of combined drug types was concentrated around three and two types in both groups(Baloxavir Marboxil group:41.34%and 39.66%;Oseltamivir group:44.54%and 36.97%).This study highlighted that the new drug,Baloxavir Marboxil,offered certain therapeutic benefits over Oseltamivir in treating influenza among children aged 12 to 18 years,including advantages in single-dose administration,oral compliance,and specific treatment outcomes.The higher unit cost associated with Baloxavir Marboxil might be a factor for further consideration.These findings provided a new reference point for the clinical selection of anti-influenza medications.
文摘On the evening of January 25,2025 Happy Chinese New Year global launch ceremony and gala was held in Kuala Lumpur,Malaysia.This year,the“Happy Chinese New Year”event will witness nearly 500 performances and exhibitions featuring diversified forms and rich contents across more than 100 countries and regions worldwide,including activities such as the New Year Concert,square celebration,the New Year Temple Fair,global lantern lighting,Walking Reunion Dinner on Chinese Lunar New Year s Eve,so as to have the people around the world sense the unique charm of the excellent Chinese traditional culture,and jointly celebrate and enjoy the happiness of the Chinese New Year.

文摘The historical movements of relative sea level(RSL)reflect the geomorphological dynamics around coastal regions in the past,and reconstructing the RSL curve contributes to the prediction of future RSL movements.On the basis of the sediment sequence and optical stimulated luminescence(OSL)dating data of three boreholes in the Yellow River Delta(YRD),the positions of paleo-coastlines and the movements of RSL in the last 2000 years were reconstructed.The main results are as follows:1)the YRD coast transformed from a tide-dominated silty coast to a wave-dominated sandy coast and back to a tide-dominated silty coast in the last 2000 years.2)The sand layers consisting of shell fragments indicated the locations of the coastline in 1855 AD,893 AD,and 40 BC,and their top elevations were close to the mean high water level in the corresponding years.3)The mean sea level elevation in 79 BC,1019 AD,and 1800 AD relative to the modern sea level was -4.52,-4.52,and-2.92 m,respectively.4)The RSL was almost stagnant during 79 BC-1019 AD,rose slowly during 1019-1800 AD due to the reverse change of global climate from the Little Ice Age to the Medieval Warm Period,and rose significantly after 1800 AD due to the warm period.5)The movement of RSL controlled the surface slope of YRD,which was a slope of approximately 0.022‰ at 893 AD,an inverted slope of 0.144‰ at 1855 AD,and a slope of 0.075‰ recently.These findings indicate that the modern YRD is far from being abandoned in the future,providing a historical geomorphological basis for the management of the Yellow River Estuary.
