ICU-acquired weakness in critically ill patients at risk of malnutrition: risk factors, biomarkers, and early enteral nutrition impact

BACKGROUND: This study aimed to explore the risk factors associated with intensive care unitacquired weakness(ICU-AW) in critically ill patients at risk of malnutrition and to evaluate the efficacy of early enteral nutrition(EEN) and the role of biomarkers in managing ICU-AW.METHODS: This retrospective, observational cohort study included 180 patients at risk of malnutrition admitted to the emergency intensive care unit of the First Affiliated Hospital of Xiamen University Hospital from January 2022 to December 2023. Patients were divided into ICU-AW group and non-ICU-AW group according to whether they developed ICU-AW, or categorized into EEN and parenteral nutrition(PN) groups according to nutritional support. ICU-AW was diagnosed using the Medical Research Council score. The primary outcome was the occurrence of ICU-AW.RESULTS: The significant factors associated with ICU-AW included age, sex, type of nutritional therapy, mechanical ventilation(MV), body mass index(BMI), blood urea nitrogen(BUN), and creatinine(Cr) levels(P<0.05). The PN group developed ICU-AW earlier than did the EEN group, with a significant difference observed(log-rank P<0.001). Among biomarkers for ICU-AW, the mean prealbumin(PAB)/C-reactive protein(CRP) ratio had the highest diagnostic accuracy(area under the curve [AUC] 0.928, 95% confidence interval [95% CI] 0.892–0.946), surpassing the mean Cr/BUN ratio(AUC 0.740, 95% CI 0.663–0.819) and mean transferrin levels(AUC 0.653, 95% CI 0.574–0.733).CONCLUSION: Independent risk factors for ICU-AW include female sex, advanced age, PN, MV, lower BMI, and elevated BUN and Cr levels. EEN may potentially delay ICU-AW onset, and the PAB/CRP ratio may be an effective diagnostic marker for this condition.

Agricultural production structure,market conditions and farmers’nutritional intake in rural China

Nutrition poverty alleviation is an effective measure to improve the nutritional status of economically disadvantaged individuals,fundamentally improving their health and reducing poverty.Based on the Entitlement Theory and using the China Health and Nutrition Survey(CHNS)data,this paper examines the relationship between farmers’nutritional intake,production structure and regional market conditions.Results show that farmers with diversified production have better nutritional intake than those who specialize.Furthermore,the correlation between regional market conditions and nutritional intake varies between economically disadvantaged and non-economically disadvantaged households.Market conditions significantly influence the carbohydrate and fat intake of economically disadvantaged households and are positively associated with the dietary structure and nutritional intake of non-economically disadvantaged ones.Moreover,income is positively correlated with the nutritional intake of non-economically disadvantaged households but not with economically disadvantaged ones.

Nutritional Conditions for Application of Bacillus in Intensive Aquaculture of Shrimp

With the rapid development of intensive shrimp aquaculture, breeding en- vironment has been damaged severely, and diseases occur frequently. In aquacul- ture, probiotics are generally used to improve the ecological environment and inhibit pathogenic microorganisms, thereby reducing the incidence of diseases.They have been more and more commonly used in the intensive aquaculture of shrimp, and require certain nutritional conditions and need to reach a certain number to produce a good performance. In this paper, the basic nutrition requirements of the common- ly-used probiotic Bacillus and its water quality-improving effect were investigated to provide theoretical guidance for production.

Rice Germination and Its Impact on Technological and Nutritional Properties:A Review

Grain germination is a process involving numerous factors that influence the biochemical processes inside the plant cells.This review covered the abiotic factors that lead to the germination and significantly impact the nutritional properties and digestion behavior of rice grains.The macro-and micro-nutrients can be changed depending on the intensity of the applied variables during germination.For instance,germination time can increase the protein content in the grain and concurrently reduce its protein digestibility.In most cases,the number of bioactive compounds present in rice grains are increased regardless of germination conditions.Germination can promote the complexation of nutrients and thus negatively interfere with the digestibility of macronutrients.This review highlighted the influence of the germination process on the nutritional quality of rice grains,providing information about the germination conditions and their impacts on the anabolic and catabolic reactions of the grain,emphasizing the health benefits.

Drug Seeking Behavior of Amphetamine Addicted Sprague-Dawley Rats Is Eliminated after Nutritional Supplementation

Aim: The effectiveness of nutritional supplementation on drug-seeking behavior of amphetamine-addicted rats during withdrawal was investigated using a biased conditioned place preference (CPP) paradigm. Method: Twenty-four male Sprague-Dawley rats exhibiting baseline preference for the black chamber during a 20-minute pre-conditioning exploration of the CPP box completed the study. On alternate days of an 8-day schedule, twelve rats (Group AMP) were randomly selected, given either amphetamine sulfate (5 mg/ml, i.p.) and confined to the white chamber;or vehicle (1 ml saline, i.p.) and confined to the black chamber. A significant increased percentage time spent and number of entries made by Group AMP to the drug-paired, white chamber on the test day confirmed amphetamine addiction. Group AMP subsequently received increasing doses of amphetamine over 6 days. Following acute drug withdrawal, their CPP performance was compared with that of vehicle treated rats (Group SAL). Groups AMP and SAL were equally divided and randomly assigned to animals fed chow reconstituted with the nutritional supplement (AMP-S and SAL-S) over 8 weeks or standard rat chow (AMP-N and SAL-N). CPP performances for all rats were determined blindly from video recordings following this period. Results: Nutritionally supplemented, amphetamine withdrawn rats (AMP-S) exhibited significantly decreased percentage entries and time spent in the white chamber (p ?ve, control animals. Conclusion: Drug-seeking behavior by amphetamine-addicted animals was eliminated after treatment with a nutritionally supplemented diet.

Effects of fermentation conditions on bioactive substances in lactic acid bacteria-fermented soymilk and its storage stability assessment

The consumption of fermented soymilk(FSM)is of great interest to consumers because of its many potential health benefits.Nevertheless,soymilk's unpleasant flavor and astringent taste are a major concern in consumption.To obtain the soymilk with good flavor and functionality profiles,fermentation is one of the alternatives,which is why Lactobacillus plantarum NCU001563 and Streptococcus thermophilus NCU074001 were selected and used through different fermentation conditions(DFC).The single-factor test and orthogonal experiment comprehensively determine the FSM production process.The parameters of optimal conditions include mixed fermentation agents,water ratio(1:5),sterilization time(15 min),sterilization temperature(105℃),160-mesh press cloth,carbon source(glucose),amount of glucose(10%),inoculum amount(0.03%),fermented soymilk temperatures(FSM3,37℃;FSM4,42℃),and fermentation time(24 h)were retained.The DFC significantly affects nutritional factors such as proteins,amino acids,and others.At the same time,the anti-nutritional components showed the opposite results,except the total phenolic content exhibited a significantly higher content after fermentation.However,the DFC significantly decreased aldehydes such as hexanal in non-fermented soymilk(NFSM)from 19.30%to 4.97%in FSM3 and 1.60%in FSM4,respectively.Furthermore,the fermentation produced a higher abundance of 2-butanone,acetoin,and acetic acids,thus improving the overall sensory acceptability.Over time,the fermentation has been pertinent to exert preservation effects,especially for FSM4 at 4℃.The results indicated that the optimized DFCs have a good application for FSM by improving its flavor,functional profiles with health-promoting effects,and soymilk product preservations.

Drug-Seeking Behavior Is Significantly Attenuated in Nutritionally Supplemented Cocaine Withdrawn Sprague-Dawley Rats

Aim: The effect of patented nutritional supplementation on drug-seeking behavior in cocaine addicted rats during acute drug withdrawal was investigated using a biased Conditioned Place Preference (CPP) paradigm. Method: Twenty-four (24) male Sprague-Dawley rats with pre-conditioned preference for the black chamber of the CPP box were randomly divided into Cocaine (COC) or Saline (SAL) treated groups. Rats (n = 12) treated with cocaine hydrochloride 20 mg/kg/ml, i.p. (COC group) were confined individually to the white chamber on days 1, 3, 5 and 7. On alternate days, they were given 1 ml saline vehicle, i.p. and confined to the black chamber. Control rats (SAL group, n = 12) received only vehicle on all 8 days and were confined on alternate days to the white or black chamber. Positive place preference was confirmed for COC rats, which subsequently received 6 increasing daily doses of cocaine. CPP performances of both COC and SAL rats were recorded following an acute 3-day withdrawal period. All animals were then randomly assigned to rats fed either chow reconstituted with the nutritional supplement (COC-S and SAL-S) or standard rat chow (COC-N and SAL-N) for 8 weeks, followed by final CPP performances. Results: Following supplementation, COC-S rats made significantly less entries and time spent in the white chamber (p < 0.05) compared with COC-N rats. COC-S rats exhibited significant place aversion to the white chamber similar to drug-naive animals;whereas COC-N continued to show positive place preference. Conclusion: Drug-seeking behavior that persisted during cocaine withdrawal was significantly diminished in the nutritionally supplemented.

A comparison of several indices for assessing body condition of Mongolian gazelle

Riney kidney fat index (RKFI), whole kidney fat index (WKFI), femur marrow fat index (FMFI), and tibia marrow fat index (TMFI) of 51 Mongolian gazelles (Procapra gutturosa), collected in Hulunbeier grassland, Inner Mongolian, China, were measured during spring, autumn and winter in 1997-98. These different indexes were compared for using them in assessing the body condition. There was a linear relationship (y=0.9444x-20.139; r=0.9454; p<0.01) between RKFI and KMFI. A linear relationship (y=0.9348x+1.1843; r=0.9875; P<0.01) between TMFI and FMFI also occurred for gazelles. There was a curvilinear relationship (y=31.44Ln(x) -44.403; r=0.8643; P<0.01) between FMFI and RKFI. FMFI remained high, while RKFI decreased to a certain extent. After most of the kidney fat was used, the femur marrow fat abruptly decreased. The results showed that the kidney fat index is more adequate for evaluating the population nutrition in good condition, but marrow fat index was more useful for assessing in poorer nutritional condition.

Dietary fat intake of Japanese male children and its associated factors: Results of the 1995 National Nutrition Survey in Japan

Aim: To clarify the factors associated with reported dietary fat intake by Japanese male children. Methods: This study is based on the data of a nationally representative cross-sectional study in Japan. Three hundred and seventy-seven male children (age, 6 - 11 years) whose households were sampled in the 1995 Comprehensive Survey of Living Conditions of the People on Health and Welfare, and the 1995 National Nutrition Survey and whose parents were identified through record linkage between the 2 survey data sets were enrolled. Results: The final dataset in this study consisted of 377 boys with 329 of their parents. Fifty-two boys were found to be overweight (13.8%). The reported dietary fat intake was higher among the overweight boys than among the non-overweight boys. Maternal obesity was significantly associated with obesity in male children. Boys who frequently consumed foods from the “fats and lipids” group and the “meat” groups, and children from nuclear families rather than 3- generation families reported high dietary fat intake. In addition, parental fat intake was also significantly associated with fat intake of male children. Conclusions: Child and parental dietary habits along with the household status should be considered when implementing nutritional education programmes to control dietary fat intake and reduce the obesity risks of male children.

Effects of grazing intensity to water source on grassland condition, yield and nutritional content of selected grass species in Northwest Ethiopia

Background:Savanna grasslands are globally important ecosystems consisting of one of the most extensive grazing lands with unique biodiversity.The objectives of the study were to assess the effect of grazing intensity on grassland ecosystem condition,herbaceous plant biomass production,and nutritional content of selected grass species.Methods:The study was conducted at Chagni Ranch,Northwest Ethiopia.Four transects to water source point at regular intervals of 20m between sampling plots along transects were used for data collection.The distance between the four transects was 200m in radius.Data were collected on grass composition,basal cover,litter cover,number of seedlings,and age distribution of dominant grasses(i.e.,young,medium,or old in terms of stage of maturity),soil condition in terms of soil compaction,and soil erosion linked to the effects of trampling by grazing animals along transects(hereafter referred to as transect)to water source point.The total sample size for grass species was 160 plots.The grassland ecosystem condition,herbaceous biomass,and grass nutritional content were used as response variables linked to transect from water source point.The effects of transect on grassland ecosystem condition scores and grass nutritional content were analyzed using the analysis of variance(ANOVA).Results:Grassland condition factors like grass composition,basal cover,litter cover,age distribution of dominant grasses,and soil condition were significantly(P<0.05)higher for the furthest transect to water source point than nearest transect.Out of the 28 identified herbaceous species,grasses accounted for 64.3%of the herbaceous community.Within grass species,about 55.6%were highly desirable in terms of palatability and grazing value(as most palatable species are susceptible to heavy grazing intensity).The results showed a significantly(P<0.05)higher proportion of perennial grasses at the furthest transect to water source point than nearest transect.The dry matter yield at the furthest transect(TD4)and third transect(TD3)were significantly(P<0.05)higher than the nearest transect to water source point(i.e.,the first transect(TD1)and second transect(TD2)).Ash,neutral detergent fiber,acid detergent fiber,and acid detergent lignin contents of Cynodon dactylon,Sporobolus pyramidalis,and Digitaria ternata were significantly(P<0.05)higher at the furthest transect to water source point than nearest transect.Grazing intensity had no significant effect on the crude protein content of Cynodon dactylon and Sporobolus pyramidalis at different transects.Conclusions:The results showed that the furthest transect to water source point were in good condition.Grass biomass production and the nutritional contents of grasses were higher for the furthest transect to water source point.The results suggested that increased grazing intensity towards water source point greatly reduced the abundance of desirable perennial grasses and the sustainability of grassland for livestock production.
