BACKGROUND Post-transplant tertiary hyperparathyroidism(PT-tHPT)is a well-recognized complication following kidney transplantation,characterized by persistent excessive secretion of parathyroid hormone(PTH)despite improved renal function.It is potentially associated with an increased risk of cardiovascular events,renal osteodystrophy,pathologic fractures,graft loss,and mortality.AIM To evaluate the incidence,risk factors,and outcomes of PT-tHPT amongst kidney transplant recipients.METHODS A total of 887 transplant recipients who underwent transplantation between 2000 and 2020 were evaluated.Univariable and multivariable logistic regression was performed to determine the predictors of tertiary hyperparathyroidism.Graft and recipient outcomes were assessed using multivariable Cox regression.A separate multivariable Cox regression was performed to determine the effect of treatment strategies on outcomes.RESULTS PT-tHPT,defined as elevated PTH(>65 ng/L)and persistent hypercalcemia(>2.60 mmol/L),was diagnosed in 14%of recipients.Risk factors for PT-tHPT included older age[odds ratio(OR)=1.36,P<0.001],Asian ethnicity(OR=0.33,P=0.006),total ischemia time(OR=1.03,P=0.048 per hour),pre-transplant serum calcium(OR=1.38,P<0.001)per decile increase,pre-transplant PTH level(OR=1.31,P<0.001)per decile increase,longer dialysis duration(OR=1.12,P=0.002)per year,history of acute rejection(OR=2.37,P=0.012),and slope of estimated glomerular filtration rate change(OR=0.91,P=0.001).There were a 3.4-fold higher risk of death-censored graft loss and a 1.9-fold greater risk of recipient death with PT-tHPT.The three treatment strategies of conservative management,calcimimetic and parathyroidectomy did not significantly change the graft or patient outcome.CONCLUSION Pretransplant elevated calcium and PTH levels,older age and dialysis duration are associated with PT-tHPT.While PT-tHPT significantly affects graft and recipient survival,the treatment strategies did not affect survival. 展开更多

The concept of the brain cognitive reserve is derived from the well-acknowledged notion that the degree of brain damage does not always match the severity of clinical symptoms and neurological/cognitive outcomes.It has been suggested that the size of the brain(brain reserve) and the extent of neural connections acquired through life(neural reserve) set a threshold beyond which noticeable impairments occur.In contrast,cognitive reserve refers to the brain's ability to adapt and reo rganize stru cturally and functionally to resist damage and maintain function,including neural reserve and brain maintenance,resilience,and compensation(Verkhratsky and Zorec,2024). 展开更多

BACKGROUND The use of induction immunosuppression agents has improved kidney transplant outcomes,but selecting the optimal agent remains a point of debate.AIM To compare the long-term outcomes of kidney transplant recipients receiving alemtuzumab vs basiliximab induction,focusing on graft function,acute rejection,infection,malignancy,post-transplant glomerulonephritis,and survival,using a propensity score matched cohort design.METHODS Kidney transplant recipients who received alemtuzumab or basiliximab induction from 2014 to 2019 across two nephrology centres in Northwest England were evaluated.Propensity score matching at a 1:1.5 ratio ensured comparability between cohorts.Baseline characteristics,immunosuppression regimens,and outcomes were analyzed.Linear,binary logistic and Cox proportional hazard regression models.RESULTS A total of 436 recipients were included,with a median follow-up of 5.2 years.The matched cohort(n=262)had a mean age of 51.1±13.5 years;39%were female and 92%were white.There was no significant difference in the cumulative incidence of acute rejection[odds ratio(OR)=2.10;95%CI:0.9-4.9;P=0.110].Compared with basiliximab,alemtuzumab was associated with lower estimated glomerular filtration rate at 12 months(-6.6 mL/minute/1.73 m2;95%CI:-10.5 to-2.7;P<0.001)and higher risks of cytomegalovirus viremia(OR=3.2;95%CI:1.6-6.5;P<0.001),BK viremia(OR=2.4;95%CI:1.1-5.5;P=0.02),post-transplant malignancy(OR=6.2;95%CI:1.6-29.9;P=0.013),and death-censored graft loss(hazard ratio=3.6;95%CI:1.2-11.4;P=0.03).No significant differences were observed in post-transplant glomerulonephritis or recipient mortality.CONCLUSION In this propensity score-matched analysis,alemtuzumab induction was associated with lower graft function at 12 months and higher risks of viral infection,post-transplant malignancy,and graft loss compared with basiliximab.These findings highlight the need for further studies to confirm the long-term safety and effectiveness of alemtuzumab in kidney transplantation. 展开更多

While chronic hyperglycaemia resulting from poorly controlled diabetes mellitus(DM)is a well-known precursor to complications such as diabetic retinopathy,neuropathy(including autonomic neuropathy),and nephropathy,a paradoxical intensification of these complications can rarely occur with aggressive glycemic management resulting in a rapid reduction of glycated haemoglobin.Although,acute onset or worsening of retinopathy and treatment induced neuropathy of diabetes are more common among these complications,rarely other problems such as albuminuria,diabetic kidney disease,Charcot’s neuroarthropathy,gastroparesis,and urinary bladder dysfunction are also encountered.The World Journal of Diabetes recently published a rare case of all these complications,occurring in a young type 1 diabetic female intensely managed during pregnancy,as a case report by Huret et al.It is essential to have a comprehensive understanding of the pathobiology,prevalence,predisposing factors,and management strategies for acute onset,or worsening of microvascular complications when rapid glycemic control is achieved,which serves to alleviate patient morbidity,enhance disease management compliance,and possibly to avoid medico-legal issues around this rare clinical problem.This editorial delves into the dynamics surrounding the acute exacerbation of microvascular complications in poorly controlled DM during rapid glycaemic control. 展开更多

An imbalance in adenosine-mediated signaling,particularly the increased A_(2A)R-mediated signaling,plays a role in the pathogenesis of Parkinson's disease.Existing therapeutic approaches fail to alter disease progression,demonstrating the need for novel approaches in PD.Repetitive transcranial magnetic stimulation is a non-invasive approach that has been shown to improve motor and non-motor symptoms of Parkinson's disease.However,the underlying mechanisms of the beneficial effects of repetitive transcranial magnetic stimulation remain unknown.The purpose of this study is to investigate the extent to which the beneficial effects of prolonged intermittent theta burst stimulation in the 6-hydroxydopamine model of experimental parkinsonism are based on modulation of adenosine-mediated signaling.Animals with unilateral 6-hydroxydopamine lesions underwent intermittent theta burst stimulation for 3 weeks and were tested for motor skills using the Rotarod test.Immunoblot,quantitative reverse transcription polymerase chain reaction,immunohistochemistry,and biochemical analysis of components of adenosine-mediated signaling were performed on the synaptosomal fraction of the lesioned caudate putamen.Prolonged intermittent theta burst stimulation improved motor symptoms in 6-hydroxydopamine-lesioned animals.A 6-hydroxydopamine lesion resulted in progressive loss of dopaminergic neurons in the caudate putamen.Treatment with intermittent theta burst stimulation began 7 days after the lesion,coinciding with the onset of motor symptoms.After treatment with prolonged intermittent theta burst stimulation,complete motor recovery was observed.This improvement was accompanied by downregulation of the e N/CD73-A_(2A)R pathway and a return to physiological levels of A_(1)R-adenosine deaminase 1 after 3 weeks of intermittent theta burst stimulation.Our results demonstrated that 6-hydroxydopamine-induced degeneration reduced the expression of A_(1)R and elevated the expression of A_(2A)R.Intermittent theta burst stimulation reversed these effects by restoring the abundances of A_(1)R and A_(2A)R to control levels.The shift in ARs expression likely restored the balance between dopamine-adenosine signaling,ultimately leading to the recovery of motor control. 展开更多

Cultural ecosystem services(CES)provided by urban green infrastructure are essential for enhancing social well-being and resilience.Identifying and mapping CES at a local scale is crucial for informed land-use decisions that align with citizens'perceptions.However,research on ecosystem services in Romania has been limited,with a notable gap in the assessment of CES provided by urban green spaces.This study is the first to focus on Băneasa Forest,the only urban forest in Bucharest,which serves as a vital recreational area for thousands of residents and visitors.For the first time in Romania,this research uses a web-based Participatory GIS survey to collect spatially referenced data.The survey,which combines questionnaires and mapping exercises,allows us to produce high-resolution CES maps based on 816 responses.The results reveal that the forest's natural characteristics are perceived as the primary contributors to CES.These findings are valuable for urban planners,as they highlight the needs and expectations of forest visitors,promote conservation efforts,and foster collaboration to prevent conflicts.Alongside factors frequently discussed in the literature,such as age and accessibility,the percentage of green space in residents'neighborhoods emerges as a significant factor influencing CES preferences.This insight presents a novel contribution to the literature,being of particular importance for urban planners and policymakers,as it underscores the need to consider not just the green space within parks and forests,but also the broader context of surrounding neighborhoods when planning for CES.Understanding that the availability of nearby green space influences residents'CES preferences can guide more effective strategies to enhance access to CES in urban areas,both in Bucharest and elsewhere.This is especially relevant in the face of climate change and other emerging challenges,which are likely to increase the demand for CES in the future. 展开更多

Under conditions of increasing urbanization, the problem of studying the impact of synanthropic animal species on the functioning of urban ecosystems is becoming increasingly important. The purpose of this study was to identify and analyze the species composition of synanthropic birds and mammals in the urban area of Osh (Kyrgyzstan), assess the degree of their bio-damaging activity, and develop recommendations to minimize their negative impact on various sectors of the urban environment. Field studies conducted in 2023–2024 revealed 22 species of synanthropic birds and 7 species of synanthropic mammals. Among birds, representatives of Columbiformes (3 species), Apodiformes (2 species), and Passeriformes (18 species) were identified, including families Hirundinidae, Motacillidae, Sturnidae, Corvidae, Turdidae, Paridae, Passeridae, Fringillidae, and Emberizidae. All recorded mammal species belonged to Rodentia, represented by the families Gliridae, Cricetidae, Gerbillidae, and Muridae. Most of these species are closely related to human activities, including obligate and facultative synanthropes (23 species) successfully adapted to anthropogenic landscapes. There are also pseudosynanthropes (6 species) that occur in populated areas but are not directly dependent on humans. The analysis showed that synanthropic species cause considerable damage to urban agriculture, infrastructure, and utilities. Major impacts include crop destruction, deterioration of monuments, damage to networks, and disease transmission. Special attention was paid to Meriones libycus, Ellobius tancrei, and Dryomys nitedula, recently identified as synanthropic species in Kyrgyz cities. Their inclusion provides new insights into urban ecosystem dynamics. The study proposes integrated control measures, including mechanical, chemical, and biological methods for effective management of bio-damaging species. 展开更多

The article examines the impact of increased aridization of the territory due to an increase in air temperature,reduced precipitation,and the formation of moisture deficiency on grain yields in Northern Kazakhstan.The most important result of the work is the revealed inverse relationship between grain yields and the temperature of the growing season:low-yielding years are associated with high temperatures and droughts,and high-yielding years are associated with lower temperatures and an optimal ratio of heat and moisture.The novelty of this study is the use of the method of hydrological and climatic calculations in identifying the nature of temperature variability and precipitation in the territory of Northern Kazakhstan for the modern period(1991–2020)compared with the base period(1961–1990).At all the studied meteorological stations,there is a tendency for the average annual temperature and the temperature of the growing season to increase:in the forest-steppe zone with an average warming intensity of 0.3–0.33℃ per decade;in the steppe zone by 0.2–0.43℃ per decade;and in the growing season by 0.2–0.7℃ per decade.The air temperature in the steppe zone is rising more intensively than in the forest-steppe zone,and precipitation in the forest-steppe zone has changed more than in the steppe zone.An increase in the average annual air temperature during the growing season(May–August),combined with a shortage of atmospheric moisture or a constant amount of it,led to an increase in the degree of aridization of the territory,an increase in the frequency of droughts in the steppe zone of Northern Kazakhstan. 展开更多

Avian malaria,caused by parasites of the genus Plasmodium,is prevalent among wild bird populations worldwide and can have significant impact on avian health and populations.With the rise in global temperatures due to climate change,concerns have arisen about the spread of southern malaria species,that potentially can affect previously unexposed bird populations.We studied juvenile siskins infected with two distinct malaria parasites:Plasmodium relictum(SGS1 lineage)and P.ashfordi(GRW2 lineage).While the former is common in the Northern Palearctic,the latter is primarily found in Central and Southern Africa.We assessed the impact of these infections on siskins'physiological well-being using resting metabolic rate(RMR)and interleukin-6(IL-6)levels.Changes in RMR reflect the energetic cost of disease,while IL-6 serves as a one of the inflammatory cytokines in the innate immune system's response to infection.Our experimental findings reveal distinct outcomes during the acute phase of SGS1 and GRW2 infections.Infection with SGS1 was marked by reduced RMR and IL-6 levels in siskins.A similar IL-6 pattern was observed in the GRW2 group initially,though it was not sustained.Additionally,GRW2-infected siskins showed distinct RMR dynamics compared to SGS1-infected birds.Our study did not conclusively demonstrate that tropical malaria has more severe effects on siskins.However,similarities with previous studies with SGS1 infected birds and variations in disease progression between the two experimental groups underscore the complexity of host-parasite interactions in avian malaria infections. 展开更多

Carbon(δ^(13)C)and oxygen(δ^(18)O)isotope compositions are considered indicators of the effect of water conditions on plant photosynthesis(δ^(13)C)and transpiration(δ^(18)O).Hydrogen isotope composition(δ^(2)H),tracks transpiration like δ^(18)O,while also affected by the organ trophism.Such dual behaviour,together with its highly exchangeable nature have hindered the use of δ^(2)H to assess plant performance.We compared the effect of contrasting water pressure deficit(VPD)on the signatures of the three isotopes across different durum wheat parts.Plants were hydroponically grown under conditions,differing in VPD and the isotopic labelling of the nutrient solution(natural abundance versus δ^(2)H and δ^(18)O-enriched)and isotopic signatures analysed at mid-grain filling.Higher VPD increased plant-matter δ^(13)C,δ^(2)H,and δ^(18)O,in accordance with atmospheric drought decreasing stomatal conductance and transpiration.Moreover,positive correlations within and across organs betweenδ2H and δ^(18)O of organicmatter and water further supported a similar source of variation related to evaporation.However,δ^(2)H was depleted in photoautotrophic(leaves and glumes),enriched in mixotrophic(peduncle and awns)and even more in heterotrophic(grains)organs.This study highlights the similarities and differences in mechanisms determining δ^(2)H,δ^(18)O,and δ^(13)C through the interactions of these isotopes with VPD and plant organs. 展开更多

Recent research has increasingly highlighted the potential oncogenic effects of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection within the gastrointestinal tract.Growing evidence suggests that SARS-CoV-2 may contribute to the development of gastrointestinal malignancies through several mechanisms,including sustained chronic inflammation,disruption of normal cellular homeostasis,and potential viral integration into host cells.These pathological processes have the potential to dysregulate critical cellular pathways,thereby promoting cancer development in vulnerable populations.A thorough understanding of how SARS-CoV-2 interacts with the development of gastro-intestinal cancer is essential for optimizing patient care and establishing compre-hensive,long-term monitoring protocols.This review highlighted the pressing need for ongoing research into the complex relationship between SARS-CoV-2 infection and the risk of gastrointestinal cancer. 展开更多

BACKGROUND Endoscopic submucosal dissection(ESD)is increasingly used to treat gastric dysplasia and early neoplasia in the West.Unlike Eastern countries,data for Caucasian patients in the United Kingdom is limited due to its limited implementation in a few tertiary centres.AIM To evaluate the outcomes of ESD on gastric dysplasia and neoplasia in Caucasian patients.METHODS Our ten-year retrospective study at a single tertiary centre included data spanning from May 2012 to July 2023.The efficacy of ESD on gastric dysplasia and early neoplasia was measured using parameters set out by the National Institute for Health and Care Excellence,which include en-bloc and curative resection(CR)rates,local recurrence and survival rates.RESULTS ESD was attempted on 111 lesions in 93 patients.95.0%of completed procedures achieved endoscopic clearance.74.3%were en-bloc resections and the rest were hybrid ESD with piecemeal resections.In all,34.7%achieved histological CR.Overall,disease recurrence was 10.9%at latest follow-up(63 months,median follow-up).Importantly 100%of lesions in the CR group showed no disease recurrence at subsequent and latest follow-up.In the Indeterminate and Non-CR group,18.8%of lesions showed disease recurrence at subsequent endoscopic follow-ups.ESD changed the histological staging of 44.5%of lesions.Immediate complications were observed in 9.9%of all ESD procedures.The median survival time was 69 months post-ESD.The mean age at death is 82.2 years old.CONCLUSION The study affirms the long-term efficacy and safety of ESD for gastric dysplasia and early neoplasia in Caucasian patients. 展开更多

We tested the effectiveness of the gradual removal of Scots pine(Pinus sylvestris L.)in former plantations of this species in Roztocze National Park(SE Poland)to support the restoration of natural herbaceous flora and forest structure.We compared 0.5-ha study plots subjected to selective removal of pine trees with control plots excluded from any kind of human intervention for half a century.The observed changes in forest floor vegetation in the converted plots showed naturalization towards habitat-specific species.However,differences in the spatial distribution of trees between the treatment and control plots showed no universal pattern and revealed subtle but positive shifts from regular to random or clustered patterns.The mean tree diameters were higher in plots subjected to Scots pine removal,which resulted from the vigorous growth of tree species,consistent with habitat types.We conclude that forest restoration through the removal of planted trees can support the naturalization of former Scots pine plantations in protected areas.However,the selection of an appropriate method and its intensity are of vital importance.Methods that resemble typical management practices,such as selection thinning,are not always the best approach,as they may preserve or even increase the regular distribution of trees.Therefore,for restoration purposes,we recommend testing other methods that increase spatial heterogeneity,including systematic cutting or emulating natural disturbances.In addition,low-intensity thinning may not be sufficient to support the restoration of natural forest floor vegetation and the variability in forest stand structure. 展开更多

Eosinophils are multifunctional granulocytes that contribute to the initiation and modulation of inflammation.Accumulating evidence suggests that eosinophils are adaptable leukocytes that orchestrate the resolution of inflammatory responses.The most prevalent chronic inflammatory illness,rheumatoid arthritis(RA),is typified by persistent synovitis thatmakes it hard for the disease to go away on its own.Interestingly,a unique subset of eosinophils known as regulatory eosinophils has been found in RA patients’synovium,especially while the disease is in remission.Pro-resolving signatures of regulatory eosinophils in the synovium are distinct from those of their lung counterparts.The most recent research on eosinophils and their function in this disease pathogenesis is compiled in this review.Based on the role of regulatory eosinophils,a new pathological model of inflammation resolution in RA is proposed,and potential therapeutic strategies aimed at enhancing the action of regulatory eosinophils in RA are proposed. 展开更多

Neutrophil extracellular traps(NET)have emerged as critical players in the pathogenesis of atherosclerosis and other cardiovascular diseases(CVD).These web-like structures,composed of DNA,histones,and granule proteins released by neutrophils,contribute significantly to both inflammation and thrombosis.This manuscript offers a comprehensive review of the recent literature on the involvement of NET in atherosclerosis,highlighting their interactions with various pathophysiological processes and their potential as biomarkers for CVD.Notably,the impact of radiation on NET formation is explored,emphasising how oxidative stress and inflammatory responses drive NET release,contributing to plaque instability.The role of histones,particularly citrullinated histones,in endothelial dysfunction and plaque progression is discussed,highlighting their significance in the pathophysiology of atherosclerosis.Furthermore,the complex relationship between lipoproteins and NET formation is examined,with a focus on how elevated low-density lipoprotein(LDL)and decreased high-density lipoprotein(HDL)levels facilitate NET release,thus promoting vascular inflammation and plaque instability.The influence of cholesterol on NET formation is also explored,underscoring its contribution to plaque development and stability.The role of Peptidylarginine deiminase 4(PAD4)in the regulation of NETosis is reviewed,with attention given to how PAD4-driven citrullination of histones affects atherosclerosis progression.Moreover,the manuscript examines the potential of NET components—such as double-stranded DNA,myeloperoxidase–DNA complexes,and citrullinated histone H3—as biomarkers for assessing disease severity and predicting adverse cardiovascular events,including ST-elevation myocardial infarction(STEMI)and stroke.Elevated levels of these biomarkers correlate with worse clinical outcomes,suggesting their utility in guiding therapeutic interventions.In contrast to the existing body of work,this review highlights the novelty of integrating recent findings on NET interactions with lipid metabolism,histone modifications,and PAD4 activity in the context of atherosclerosis.Overall,NET plays an integral role in the inflammatory and thrombotic processes underpinning atherosclerosis,and their components hold promise as both diagnostic markers and therapeutic targets in cardiovascular disease management. 展开更多

Accurate and timely estimation of above-ground biomass is crucial for understanding crop growth dynamics,optimizing agricultural input management,and assessing productivity in sustainable farming practices.However,conventional biomass assessments are destructive and resource-intensive.In contrast,remote sensing techniques,particularly those utilizing low-altitude unmanned aerial vehicles,provide a non-destructive approach to collect imagery data on plant canopy features,including spectral reflectance and structural details at any stage of the crop life cycle.This study explores the potential visible-light-derived vegetative indices to improve biomass prediction during the flowering period of buckwheat(Fagopyrum tataricum).Red,green,and blue(RGB)images of buckwheat were acquired during peak flowering,using a DJI P4 multispectral Drone.From the analysis of those images,four vegetative indices were calculated.Aboveground fresh biomass was harvested and measured on 14 September 2024.The results showed negative correlations between the green-band based excess green(ExG),excess green minus excess red(ExGR),and green leaf index(GLI)indices and the fresh above-ground biomass of buckwheat,while the red band-based excess red(ExR)index showed an insignificant positive correlation at p<0.10.An investigation into greenband-based vegetation indices(VIs)for estimating fresh biomass revealed significant negative correlations during the experimental period.This unexpected inverse relationship is attributed to spectral interference from abundant white flowers during the flowering stage,where the high reflectance of white petals masked the green vegetation signal.Consequently,these green-band VIs demonstrated limited predictive power for biomass under such conditions,indicating that their utility is compromised when floral reflectance is dominant.Therefore,we suggest that further experiments are required to validate this relationship and improve the estimation of fresh above-ground biomass in white-flowered buckwheat plants. 展开更多
