Fodder production in arid rangelands has been traditionally considered as the main source of nutrition for livestock.However,the production of these fodder may be influenced by some socio-economic and climatic factors.This study aims to identify the various rangeland use forms and determine the types of livestock feeding system in the El Ouara rangelands of Ben guarden District in southern Tunisia by analysing the importance of supplemental feeding and main determinants of this practice.Data were collected by a survey that targeted a sample of 50 breeders in the El Ouara rangelands.Descriptive statistics and binary logistic regression were used to analyse the data.The results showed that there are two types of association practiced by breeders:“Cherka”association practiced by 10.00% of breeders and cash payment association practiced by 53.00% of breeders.Then,transhumance,sedentary,and semi-urban forms are the main ways in which breeders use the rangelands.There are four livestock feeding systems in the El Ouara rangelands being used to feed livestock:natural rangeland,rangeland-based,mixed,and concentrate-based feeding systems.Supplemental feeding has become fundamental for the livestock feeding system in the El Ouara rangelands.The breeders with the largest camel size still use the natural rangeland feeding system,while the breeders who have the largest herd size practice the mixed feeding system.The logistic regression results reveal that breeder age,cereal area,herd size,migrant remittance,second activity,and agricultural development group membership can significantly impact the supplemental feeding.In summary,this study can help policy-makers plan innovative practices based on climatic change,ensure the sustainability of livestock feeding system,and make effective decisions for local development. 展开更多

BACKGROUND Hypoxemia due to respiratory depression and airway obstruction during upper gastrointestinal endoscopy with sedation is a common concern.The Wei nasal jet tube(WNJT)is a new nasopharyngeal airway with the ability to provide supraglottic jet ventilation and oxygen insufflation via its built-in wall channel.The available evidence indicates that with a low oxygen flow,compared with nasal cannula,the WNJT does not decrease the occurrence of hypoxemia during upper gastrointestinal endoscopy with propofol sedation.To date,there has been no study assessing the performance of WNJT for supplemental oxygen during upper gastrointestinal endoscopy with sedation when a moderate oxygen flow is used.AIM To determine whether the WNJT performs better than the nasal prongs for the prevention of hypoxemia during gastroscopy with propofol mono-sedation when a moderate oxygen flow is provided in patients with a normal body mass index.METHODS This study was performed in 291 patients undergoing elective gastroscopy with propofol mono-sedation.Patients were randomized into one of two groups to receive either the WNJT(WNJT group,n=147)or the nasal cannula(nasal cannula group,n=144)for supplemental oxygen at a 5-L/min flow during gastroscopy.The lowest SpO2 during gastroscopy was recorded.The primary endpoint was the incidence of hypoxemia or severe hypoxemia during gastroscopy.RESULTS The total incidence of hypoxemia and severe hypoxemia during gastroscopy was significantly decreased in the WNJT group compared with the nasal cannula group(P=0.000).The lowest median SpO2 during gastroscopy was significantly higher(98%;interquartile range,97-99)in the WNJT group than in the nasal cannula group(96%;interquartile range,93-98).Epistaxis by device insertion in the WNJT group occurred in 7 patients but stopped naturally without any treatment.The two groups were comparable in terms of the satisfaction of physicians,anesthetists and patients.CONCLUSION With a moderate oxygen flow,the WNJT is more effective for the prevention of hypoxemia during gastroscopy with propofol mono-sedation compared with nasal prongs,but causing slight epistaxis in a few patients. 展开更多

BACKGROUND Hypoxemia is a common complication in obese patients during gastroscopy with sedation.The Wei nasal jet tube(WNJT)is a new special nasopharyngeal airway with the ability to provide supraglottic jet ventilation and oxygen insufflation via its built-in wall channels.The aim of this study was to compare the efficacy and safety of the WNJT vs a nasal cannula for supplemental oxygen during gastroscopy with propofol mono-sedation in obese patients.AIM To compare the efficacy and safety of the WNJT vs a nasal cannula for supplemental oxygen during gastroscopy with propofol mono-sedation in obese patients.METHODS A total of 103 obese patients with a body mass index of 30 kg/m2 or more undergoing elective gastroscopy under propofol mono-sedation were randomly assigned to receive supplemental oxygen at 5 L/min through either a WNJT(WNJT group,n=51)or a nasal cannula(nasal cannula group,n=52).The lowest pulse oxygen saturation(SpO2)and mild and severe hypoxemia during gastroscopy were recorded.The primary outcome was the incidence of hypoxemia.RESULTS The lowest SpO2 during gastroscopy with propofol mono-sedation was significantly increased in the WNJT group compared with the nasal cannula group.The incidence of mild hypoxemia and total incidence of hypoxemia were significantly lower in the WNJT group than in the nasal cannula group.Other than a higher incidence of epistaxis in the WNJT group,the occurrence of adverse events was similar between the devices.While neither device demonstrated a statistically significant difference in satisfaction among patients,the WNJT did result in improved satisfaction among anesthetists and physicians.CONCLUSION During gastroscopy with propofol mono-sedation in obese patients,the WNJT,when compared with a nasal cannula for supplemental oxygen,can significantly reduce the occurrence of hypoxemia and improve both arterial oxygenation and satisfaction among anesthetists and physicians.The use of the WNJT may,however,lead to epistaxis in a few patients.In view of this clinically acceptable risk-benefit ratio,the WNJT may be recommended as an alternative tool for supplemental oxygen for the prevention of hypoxemia during gastroscopy with propofol mono-sedation in obese patients. 展开更多

Ridge-furrow rainwater harvesting(RFRH) planting pattern can lessen the effect of water deficits throughout all crop growth stages, but water shortage would remain unavoidable during some stages of crop growth in arid and semiarid areas. Supplemental irrigation would still be needed to achieve a higher production. Field experiments were conducted for two growing seasons(2012–2013 and 2013–2014) to determine an appropriate amount of supplemental irrigation to be applied to winter oilseed rape at the stem-elongation stage with RFRH planting pattern. Four treatments, including supplemental irrigation amount of 0(I1), 60 mm(I2) and 120 mm(I3) with RFRH planting pattern and a control(CK) irrigated with 120 mm with flat planting pattern, were set up to evaluate the effects of supplemental irrigation on aboveground dry matter(ADM), nitrogen nutrition index(NNI), radiation use efficiency(RUE), water use efficiency(WUE), and seed yield and oil content of the oilseed rape. Results showed that supplemental irrigation improved NNI, RUE, seed yield and oil content, and WUE. However, the NNI, RUE, seed yield and oil content, and WUE did not increase significantly or even showed a downward trend with excessive irrigation. Seed yield was the highest in I3 for both growing seasons. Seed yield and WUE in I3 averaged 3 235 kg ha^(–1) and 8.85 kg ha^(–1) mm^(–1), respectively. The highest WUE was occurred in I2 for both growing seasons. Seed yield and WUE in I2 averaged 3 089 kg ha^(–1) and 9.63 kg ha^(–1) mm^(–1), respectively. Compared to I3, I2 used 60 mm less irrigation amount, had an 8.9% higher WUE, but only 4.5 and 0.4% lower seed yield and oil content, respectively. I2 saved water without substantially sacrificing yield or oil content, so it is recommended as an appropriate cultivation and irrigation schedule for winter oilseed rape at the stem-elongation stage. 展开更多

Based on split plot design method of field test,the impacts of supplemental irrigation based on soil moisture measurement and nitrogen use on winter wheat yield and nitrogen absorption and distribution were studied.Supplemental irrigation had three levels: 60%(W_1),70%(W_2) and 80%(W3) of the targeted relative water content at 0-40 cm of soil layer during jointing period of winter wheat.Nitrogen fertilization had three levels: not using nitrogen(N_0),using pure nitrogen of 195 kg/hm^2(N_(195)) and 255 kg/hm^2(N_(255)).Results showed that:(i)different supplemental irrigation and nitrogen fertilization significantly affected plant height and leaf area of winter wheat during key growth period.Under the same supplemental irrigation treatment,both plant height and leaf area of winter wheat showed as N_(255)> N_(195)> N_0(P <0.05).Plant height in N_(195) and N_(255)treatments was significantly higher than that in N_0 treatment,but there was not significant difference between N_(195) and N_(255)(P >0.05).Under the same nitrogen fertilization,plant height in W_2(569.4 m^3/hm^2) and W3(873.45 m^3/hm^2) treatments was significant higher than that in W_1(265.2 m^3/hm^2),but there was not significant difference between W_2 and W3(P >0.05).It illustrated that excessive nitrogen fertilization and supplemental irrigation did not significantly affect plant height and leaf area of winter wheat.(ii) Under the same nitrogen fertilization level,yield increase effect of winter wheat by supplemental irrigation showed a declining trend with nitrogen application amount increased.It illustrated that nitrogen fertilization and supplemental irrigation had certain critical values on the yield of winter wheat.When surpassing the critical value,the yield declined.When nitrogen fertilization amount was 195 kg/hm^2,and supplemental irrigation amount was 70% of field moisture capacity(569.4 m^3/hm^2),the highest yield 8500 kg/hm^2 could be obtained.(iii) During mature period of winter wheat,nitrogen accumulation amount of plant treated by nitrogen was significantly higher than that not treated by nitrogen(P <0.05).But under the treatments of W_2 and W3,nitrogen accumulation amount in N_(255) significantly declined when compared with N_(195)(P <0.05).Especially under W3(873.45 m^3/hm^2) level,nitrogen accumulation amount in N_(255) was even lower than N_0.Under the treatments of N_0 and N_(195),nitrogen accumulation amount of plant significantly increased with supplemental irrigation increased(P < 0.05).But under N_(255) treatment,there was not significant difference(P > 0.05).It illustrated that moderate supplemental irrigation and nitrogen fertilization could improve nitrogen absorption ability of winter wheat,but excessive supplemental irrigation and nitrogen fertilization were not favorable for plant's nitrogen absorption.(iv) Although the increase of supplemental irrigation during jointing period improved nitrogen absorption ability of winter wheat and promoted winter wheat absorbing more nitrogen,it inhibited nitrogen transferring and distributing to seed.Comprehensively considering growth condition of winter wheat and nitrogen risk condition,it is suggested that nitrogen application amount was 195 kg/hm^2,and supplemental irrigation reached 70% of field moisture capacity(569.4 m^3/hm^2),which could be as the suitable water and fertilizer use amounts in the region. 展开更多

This paper provides empirical evidence that improved supplemental irrigation (ISI) can be justified on both environmental and economic grounds. Results of a stochastic frontier model which explicitly and simultaneously accounts for technical inefficiency and production risk applied to data collected from 513 wheat farms in the rainfed areas of Syria show that the typical adopter farmer obtained yield and productive efficiency gains of 6% and 7% respectively. A stochastic dominance criterion also showed that the adopter farmers got 10% and 13% reductions in risk of obtaining yield levels below 4 tons/ha and 3 tons/ha respectively. Given its adoption level of 22.3% in 2010, ISI led to the production of 52 thousand metric tons (6%), more wheat and conservation of 120 million cubic meters of water (10%). ISI has the potential to reduce total irrigation water use by upto 45% and for further increases in yield if accompanied with sprinklers and other improved agronomic practices, thereby enhancing food security and environmental sustainability in the country. An important policy implication of these findings is that wider dissemination of ISI along with other complementary agronomic practices in postwar Syria could be a viable option to be considered by national and international efforts for the restoration and rehabilitation of agriculture in the country. 展开更多

Quantitative Precipitation Forecast(QPF)is a challenging issue in seamless prediction.QPF faces the following difficulties:(i)single rather than multiple model products are still used;(ii)most QPF methods require long-term training samples not easily available,and(iii)local features are insufficiently reflected.In this work,a multi-model blending(MMB)algorithm with supplemental grid points(SGPs)is experimented to overcome these shortcomings.The MMB algorithm includes three steps:(1)single-model bias-correction,(2)dynamic weight MMB,and(3)light-precipitation elimination.In step 1,quantile mapping(QM)is used and SGPs are configured to expand the sample size.The SGPs are chosen based on similarity of topography,spatial distance,and climatic characteristics of local precipitation.In step 2,the dynamic weight MMB uses the idea of ensemble forecasting:a precipitation process can be forecast if more than 40% of the models predict such a case;moreover,threat score(TS)is used to update the weights of ensemble members.Finally,in step 3,the number of false alarms of light precipitation is reduced,thus alleviating unreasonable expansion of the precipitation area caused by the blending of multiple models.Verification results show that using the MMB algorithm has effectively improved the TS and bias score(BS)for blended 6-h QPF.The rate of increase in TS for heavy rainfall(25-mm threshold)reaches 20%-40%;in particular,the improvement has reached 47.6% for forecast lead time of 24 h,compared with the ECMWF model.Meanwhile,the BS is closer to 1,which is better than any single-model forecast.In sum,the QPF using MMB with SGPs shows great potential to further improve the present operational QPF in China. 展开更多

Metastasis remains the primary cause for mortality of breast cancer.Despite advances in current therapeutic agents,patients with metastatic breast cancer still have poor prognoses.Tumor hypoxia,a key microenvironment factor,is emerging as an attractive target to prevent metastasis and is also involved with resistance to phototherapy.Here,we show an effective nanotherapeutic approach based on manganese dioxide-coated polydopamine nanocarriers to trigger robust anti-tumor and anti-metastasis responses against metastatic breast cancer by supplemental oxygenation and multimodal imaging-guided phototherapies.In cancer cells,the produced oxygen by the developed nanoplatform decreases the expression of hypoxia-inducible factors 1 a to inhibit tumor metastasis,and enhances the efficacy of photodynamic therapy.This nanotherapeutic approach enables the combined photodynamic/photothermal treatments with great inhibition on cell migration and invasion in vitro.Moreover,the nanotherapeutics effectively suppresses primary tumor progress and inhibits lung metastasis in v ivo in a breast cancer mouse model with satisfying biosafety.This study suggests that the tumor hypoxia-targeting nanotherapeutics have great potential for preventing and treating metastatic cancers. 展开更多

Background:This study aimed to determine the effect of different carbohydrate(CHO)doses on exercise capacity in patients with McArdle disease—the paradigm of“exercise intolerance”,characterized by complete muscle glycogen unavailability—and to determine whether higher exogenous glucose levels affect metabolic responses at the McArdle muscle cell(in vitro)level.Methods:Patients with McArdle disease(n=8)and healthy controls(n=9)underwent a 12-min submaximal cycling constant-load bout followed by a maximal ramp test 15 min after ingesting a non-caloric placebo.In a randomized,double-blinded,cross-over design,patients repeated the tests after consuming either 75 g or 150 g of CHO(glucose:fructose=2:1).Cardiorespiratory,biochemical,perceptual,and electromyographic(EMG)variables were assessed.Additionally,glucose uptake and lactate appearance were studied in vitro in wild-type and McArdle mouse myotubes cultured with increasing glucose concentrations(0.35,1.00,4.50,and 10.00 g/L).Results:Compared with controls,patients showed the“classical”second-wind phenomenon(after prior disproportionate tachycardia,myalgia,and excess electromyographic activity during submaximal exercise,all p<0.05)and an impaired endurance exercise capacity(-51%ventilatory threshold and55%peak power output,both p<0.001).Regardless of the CHO dose(p<0.05 for both doses compared with the placebo),CHO intake increased blood glucose and lactate levels,decreased fat oxidation rates,and attenuated the second wind in the patients.However,only the higher dose increased ventilatory threshold(+27%,p=0.010)and peak power output(+18%,p=0.007).In vitro analyses revealed no differences in lactate levels across glucose concentrations in wild-type myotubes,whereas a doseresponse effect was observed in McArdle myotubes.Conclusion:CHO intake exerts beneficial effects on exercise capacity in McArdle disease,a condition associated with total muscle glycogen unavailability.Some of these benefits are dose dependent. 展开更多

Background:The purported ergogenic and health effects of probiotics have been a topic of great intrigue among researchers,practitioners,and the lay public alike.There has also been an increased research focus within the realm of sports science and exercise medicine on the athletic gut microbiota.However,compared to other ergogenic aids and dietary supplements,probiotics present unique study challenges.The objectives of this systematic scoping review were to identify and characterize study methodologies of randomized controlled trials investigating supplementation with probiotics in athletes and physically active individuals.Methods:Four databases(MEDLINE,CINAHL,Cochrane CENTRAL,and Cochrane Database of Systematic Reviews)were searched for randomized controlled studies involving healthy athletes or physically active individuals.An intervention with probiotics and inclusion of a control and/or placebo group were essential.Only peer-reviewed articles in English were considered,and there were no date restrictions.Results were extracted and presented in tabular form to detail study protocols,characteristics,and outcomes.Bias in randomized controlled trials was determined with the RoB 2.0 tool.Results:A total of 45 studies were included in the review,with 35 using a parallel group design and 10 using a cross-over design.Approximately half the studies used a single probiotic and the other half a multi-strain preparation.The probiotic dose ranged from 2×10^(8)to 1×10^(11)colony forming units daily,and the length of intervention was between 7 and 150 days.Fewer than half the studies directly assessed gastrointestinal symptoms,gut permeability,or the gut microbiota.The sex ratio of participants was heavily weighted toward males,and only 3 studies exclusively investigated females.Low-level adverse events were reported in only 2 studies,although the methodology of reporting varied widely.The risk of bias was generally low,although details on randomization were lacking in some studies.Conclusion:There is a substantial body of research on the effects of prob iotic supplementation in healthy athletes and physically active individuals.Considerable heterogeneity in probiotic selection and dosage as well as outcome measures has made clinical and mechanistic interpretation challenging for both health care practitioners and researchers.Attention to issues of randomization of participants,treatments and interventions,selection of outcomes,demographics,and reporting of adverse events will facilitate more trustworthy interpretation of probiotic study results and inform evidence-based guidelines. 展开更多

Shorebird populations are declining worldwide,mainly due to human disturbances and loss of coastal wetlands.However,supratidal habitats as saltpans could play a role in buffering human impact.Saltpans have shown to be important as feeding or breeding sites of some shorebird species.A potential conservation strategy to increase shorebird populations in saltpans is to manipulate the cues that birds use to select optimal breeding habitat.Here it is hypothesized that shorebirds are attracted to bivalve shells due to the advantages they offer.Following this hypothesis,we supplemented a restored saltpan in 2019 and 2021 with bivalve shells,expecting an increase in the number of breeding birds’ nests.More than 75% of Kentish Plover(Charadrius alexandrinus) and Little Tern(Sternula albifrons) nests were found in patches with shells in both years.The best model for both species indicates that the presence of shells is the factor that most correlates with the location of nests.The probability of choosing one place over another to settle their nest increases in areas with an abundance of shells,double in the case of the Kentish Plover and triple in the case of the Little Tern.The result of this study may constitute a valuable tool for attracting birds to restored saltpans and could contribute to the success of expensive restoration projects where time is usually a constraint. 展开更多

Malaria presents a significant global public health challenge,with severe malarial anaemia being a primary manifestation of the disease.The understanding of anaemia caused by malaria remains incomplete,making the treatment more complex.Iron is a crucial micronutrient essential for haemoglobin synthesis,oxygen delivery,and other vital metabolic functions in the body.It is indispensable for the growth of human beings,as well as bacteria,protozoa,and viruses in vitro and in vivo.Iron deficiency is among the most common nutritional deficiencies and can have detrimental effects during developmental stages of life.Malaria-induced iron deficiency occurs due to the hemolysis of erythrocytes and the suppression of erythropoiesis,leading to anaemia.Meeting iron requirements is particularly critical during pivotal life stages such as pregnancy,infancy,and childhood.Dietary intake alone may not suffice to meet adequate iron requirements,thus highlighting the vital role of iron supplementation.While iron supplementation can alleviate iron deficiency,it can exacerbate malaria infection by providing additional iron for the parasites.However,in the context of pregnancy and childhood,iron supplementation combined with malaria prevention and treatment has been shown to be beneficial in improving birth outcomes and ensuring proper growth and development,respectively.This review aims to identify the role and impact of iron supplementation in malaria infection during the life stages of pregnancy and childhood. 展开更多

Background This study investigated the effects of inorganic and organic minerals on physiological responses,oxidative stress reduction,and rumen microbiota in Holstein bull calves(123.81±9.76 kg;5 months old)during short-term heat stress(HS)and recovery periods.Eight Holstein calves were randomly assigned to four treatment groups:no mineral supplementation(Con),inorganic minerals(IM),organic minerals(OM),and high-concentration organic minerals(HOM)and two thermal environments(HS and recovery)using 4×2 factorial arrangement in a crossover design of four periods of 35 d.Calves were maintained in a temperature-controlled barn.The experimental period consisted of 14 d of HS,14 d of recovery condititon,and a 7-d washing period.Results Body temperature and respiration rate were higher in HS than in the recovery conditions(P<0.05).Selenium concentration in serum was high in the HOM-supplemented calves in both HS(90.38μg/dL)and recovery periods(102.00μg/dL)(P<0.05).During the HS period,the serum cortisol was 20.26 ng/mL in the HOM group,which was 5.60 ng/mL lower than in the control group(P<0.05).The total antioxidant status was the highest in the OM group(2.71 mmol Trolox equivalent/L),followed by the HOM group during HS,whereas it was highest in the HOM group(2.58 mmol Trolox equivalent/L)during the recovery period(P<0.05).Plasma malondialdehyde and HSP70 levels were decreased by HOM supplementation during the HS and recovery periods,whereas SOD and GPX levels were not significantly affected(P>0.05).The principal coordinate analysis represented that the overall rumen microbiota was not influenced by mineral supplementation;however,temperature-induced microbial structure shifts were indicated(PERMANOVA:P<0.05).At the phylum level,Firmicutes and Actinobacteria decreased,whereas Fibrobacteres,Spirochaetes,and Tenericutes increased(P<0.05),under HS conditions.The genus Treponema increased under HS conditions,while Christensenella was higher in recovery conditions(P<0.05).Conclusion HOM supplementation during HS reduced cortisol concentrations and increased total antioxidant status in Holstein bull calves,suggesting that high organic mineral supplementation may alleviate the adverse effects of HS. 展开更多

The resource of Fenneropenaeus chinensis has declined sharply due to excessive fishing intensity,ecological changes and diseases.In order to supplement the fishing yield and restore resources of F.chinensis,the relevant authorities have carried out the activities of stock enhancement and releasing.It can increase biomass and recover resources.However,compared with increasing biomass,there were still few reports on its effect on the recovery of resources.Resource recovery is a process related to whether the released individuals can form a reproductive population.Up to now,there has been a lack of evidence whether the released F.chinensis can complete the entire life history,and form reproduction population.In this study,gravid female shrimp after spawning migration were captured from coastal waters of Haiyang,Qingdao,and Yellow Sea.After identifying parentage relationships using simple sequence repeat(SSR)and mtDNA haplotype,it was finally confirmed that there were eight released individuals in the recapture samples.It was confirmed for the first time that at least part of the released F.chinensis can complete overwintering and reproductive migration,and maintain the migration habits as their wild counterparts.Therefore,we infered that the released shrimp can reproduce under natural conditions,these F.chinensis can form reproductive populations theoretically if without human intervention.These results indicated that enhancenment and release activities have a positive effect on resource recovery. 展开更多

Alzheimer’s disease(AD),the major form of neurodegenerative diseases that can severely impede normal cognitive function,makes it one of the most common fatal diseases.There are currently over 50 million AD patients worldwide.The neuropathology of AD is perplexing and there is a scarcity of disease-modifying treatments.Currently,early diagnosis of AD has been made possible with the discovery of biological markers associated with pathology,providing strong support for the improvement of the disease status.The search for inhibitors of AD markers from dietary supplements(DSs)has become a major hot topic.Especially with the widespread use of DSs,DSs containing polyphenols,alkaloids,terpenes,polysaccharides and other bioactive components can prevent AD by reducing Aβdeposition,inhibiting tau protein hyperphosphorylation,reconstructing synaptic dysfunction,weakening cholinesterase activity,regulating mitochondrial oxidative stress,neuronal inflammation and apoptosis.This review summarizes the anti-AD effects of the main DSs and their bioactive constituents,as well as the potential molecular mechanisms covers from 2017 to 2023.Additionally,we discussed the opportunities and challenges faced by DSs in the process of AD prevention and treatment,aiming to further provide new perspectives for functional food development. 展开更多

BACKGROUND Sepsis exacerbates intestinal microecological disorders leading to poor prognosis.Proper modalities of nutritional support can improve nutrition,immunity,and intestinal microecology.AIM To identify the optimal modality of early nutritional support for patients with sepsis from the perspective of intestinal microecology.METHODS Thirty patients with sepsis admitted to the intensive care unit of the General Hospital of Ningxia Medical University,China,between 2019 and 2021 with indications for nutritional support,were randomly assigned to one of three different modalities of nutritional support for a total of 5 d:Total enteral nutrition(TEN group),total parenteral nutrition(TPN group),and supplemental parenteral nutrition(SPN group).Blood and stool specimens were collected before and after nutritional support,and changes in gut microbiota,short-chain fatty acids(SCFAs),and immune and nutritional indicators were detected and compared among the three groups.RESULTS In comparison with before nutritional support,the three groups after nutritional support presented:(1)Differences in the gut bacteria(Enterococcus increased in the TEN group,Campylobacter decreased in the TPN group,and Dialister decreased in the SPN group;all P<0.05);(2)different trends in SCFAs(the TEN group showed improvement except for Caproic acid,the TPN group showed improvement only for acetic and propionic acid,and the SPN group showed a decreasing trend);(3)significant improvement of the nutritional and immunological indicators in the TEN and SPN groups,while only immunoglobulin G improved in the TPN group(all P<0.05);and(4)a significant correlation was found between the gut bacteria,SCFAs,and nutritional and immunological indicators(all P<0.05).CONCLUSION TEN is recommended as the preferred mode of early nutritional support in sepsis based on clinical nutritional and immunological indicators,as well as changes in intestinal microecology. 展开更多

BACKGROUND The surge in traditional herbal dietary supplement(HDS)popularity has led to increased drug-induced liver injuries(DILI).Despite lacking evidence of efficacy and being prohibited from making medical claims,their acceptance has risen over sevenfold in the last two decades,with roughly 25%of United States(US)adults using these supplements monthly.An estimated 23000 emergency room visits annually in the US are linked to HDS side effects.NIH-funded research suggests HDS contribute to 7-20%of DILI cases,with similar trends in Europe—Spain reporting 2%and Iceland up to 16%.Patients with acute liver failure from HDS undergo liver transplantation more frequently than those from prescription medicines.Here we describe a case of drug-induced autoimmune hepatitis due to Skullcap supplements,this association appears to be the first documented instance in literature.CASE SUMMARY A middle-aged Caucasian woman,previously healthy,presented with sudden jaundice.Four months earlier,her liver enzymes were normal.She mentioned recent use of Skullcap mushroom supplements.Tests for chronic liver disease were negative.The first liver biopsy indicated severe resolving drug-induced liver injury.Despite treatment,she was readmitted due to worsening jaundice.Followup tests raised concerns about autoimmune hepatitis.A subsequent biopsy confirmed this diagnosis.The patient responded as expected to stopping the medication with improvement in liver enzymes.CONCLUSION This scenario highlights an uncommon instance of DILI caused by Skullcap supplements.It's crucial for hepatologists to recognize this connection due to the increasing prevalence of herbal supplements. 展开更多
