Background: While causing a financial and economic loss in many countries in a few months, COVID 19 was of great impact on public health. The Iraqi government took several measures since the first Iraqi case was discovered in February 2020. One of the fundamental measures to control this pandemic is social isolation, which depends greatly on people’s awareness to decrease the incidence of COVID-19. Objectives: To study the COVID-19-effect on dentists’ social life and their future plan, and to find the relation between that effect and some dentists’ demographic variables. Methods: A cross-sectional study was conducted from 2nd January to 7th May 2021, by an electronic version of the questionnaire through Google form. With facilitating orders delivered to all the specialist dental centers for adults of Al-Resafa health directorate;any dentists working in specialist dental centers for adults of Al-Resafa health directorate, and accept to participate in this study. Results: A total of 10 specialist dental centers for adults of the Al-Resafa health directorate represent 566/628 dentists enrolled in this study with a response rate of 88.99%. Most of them aged less than 30 years old (62.2%), female (60.6%), married status (50.4%), had 1 - 3 children (71.91%), Rotator (51.1%), with less than five years of experience (61.3%). Conclusion: COVID-19 affected so many aspects of health workers’ lives including dentists. About two-thirds of dentists had negative feelings, of which almost all had anxiety. Younger ages, females, married and having children are factors that contribute to the affection of dental social lives more than other categories. 展开更多

Neuronal plasticity,the brain's ability to adapt structurally and functionally,is essential for learning,memory,and recovery from injuries.In neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease,this plasticity is disrupted,leading to cognitive and motor deficits.This review explores the mechanisms of neuronal plasticity and its effect on Alzheimer's disease and Parkinson's disease.Alzheimer's disease features amyloid-beta plaques and tau tangles that impair synaptic function,while Parkinson's disease involves the loss of dopaminergic neurons affecting motor control.Enhancing neuronal plasticity offers therapeutic potential for these diseases.A systematic literature review was conducted using databases such as PubMed,Scopus,and Google Scholar,focusing on studies of neuronal plasticity in Alzheimer's disease and Parkinson's disease.Data synthesis identified key themes such as synaptic mechanisms,neurogenesis,and therapeutic strategies,linking molecular insights to clinical applications.Results highlight that targeting synaptic plasticity mechanisms,such as long-term potentiation and long-term depression,shows promise.Neurotrophic factors,advanced imaging techniques,and molecular tools(e.g.,clustered regularly interspaced short palindromic repeats and optogenetics)are crucial in understanding and enhancing plasticity.Current therapies,including dopamine replacement,deep brain stimulation,and lifestyle interventions,demonstrate the potential to alleviate symptoms and improve outcomes.In conclusion,enhancing neuronal plasticity through targeted therapies holds significant promise for treating neurodegenerative diseases.Future research should integrate multidisciplinary approaches to fully harness the therapeutic potential of neuronal plasticity in Alzheimer's disease and Parkinson's disease. 展开更多

Kidney transplantation(KT)accounts for nearly three-fourths of organ transplants in India,with living donors contributing to 82%of cases.Induction immunosuppression is essential to optimize initial immunosuppression,reduce acute rejections,and enable tailored use of maintenance agents.Rabbit anti-thymocyte globulin(rATG)and interleukin-2 receptor anatagonists(IL-2RA/IL-2RBs)are the most widely used induction therapies.However,data on induction practices across India are limited.To evaluate induction immunosuppression practices across KT centers in India and establish a consensus for different subsets of KT recipients.A nationwide online survey was conducted by the Indian Society of Organ Transplantation(ISOT)among its members(400 KT centers).Responses were analyzed to assess induction practices across diverse donor types,age groups,and immunological risk profiles.Heterogeneity in practices prompted consensus building using a modified Delphi process.Literature review and expert panel discussions(April 2024)were followed by structured voting,and 16 consensus statements were finalized.Of 400 centers approached,254 participated.rATG was the most commonly used induction therapy,followed by IL-2RBs;alemtuzumab was least used.Significant heterogeneity was observed in type,dose,and duration of induction therapy.Consensus recommendations were framed:rATG for high immunological risk recipients and deceased donor KTs;IL-2RB or low-dose rATG for low immunological risk;rituximab in ABOincompatible KTs;and tailoring based on age,diabetes,donor type,infection risk,and affordability.This first ISOT consensus provides 16 India-specific statements on induction therapy in KT.It emphasizes risk-stratified,evidenceinformed,and context-appropriate induction strategies,supporting standardization of care across the country. 展开更多

This paper highlights the crucial role of Indonesia’s GNSS receiver network in advancing Equatorial Plasma Bubble(EPB)studies in Southeast and East Asia,as ionospheric irregularities within EPB can disrupt GNSS signals and degrade positioning accuracy.Managed by the Indonesian Geospatial Information Agency(BIG),the Indonesia Continuously Operating Reference Station(Ina-CORS)network comprises over 300 GNSS receivers spanning equatorial to southern low-latitude regions.Ina-CORS is uniquely situated to monitor EPB generation,zonal drift,and dissipation across Southeast Asia.We provide a practical tool for EPB research,by sharing two-dimensional rate of Total Electron Content(TEC)change index(ROTI)derived from this network.We generate ROTI maps with a 10-minute resolution,and samples from May 2024 are publicly available for further scientific research.Two preliminary findings from the ROTI maps of Ina-CORS are noteworthy.First,the Ina-CORS ROTI maps reveal that the irregularities within a broader EPB structure persist longer,increasing the potential for these irregularities to migrate farther eastward.Second,we demonstrate that combined ROTI maps from Ina-CORS and GNSS receivers in East Asia and Australia can be used to monitor the development of ionospheric irregularities in Southeast and East Asia.We have demonstrated the combined ROTI maps to capture the development of ionospheric irregularities in the Southeast/East Asian sector during the G5 Geomagnetic Storm on May 11,2024.We observed simultaneous ionospheric irregularities in Japan and Australia,respectively propagating northwestward and southwestward,before midnight,whereas Southeast Asia’s equatorial and low-latitude regions exhibited irregularities post-midnight.By sharing ROTI maps from Indonesia and integrating them with regional GNSS networks,researchers can conduct comprehensive EPB studies,enhancing the understanding of EPB behavior across Southeast and East Asia and contributing significantly to ionospheric research. 展开更多

BACKGROUND Monkeypox(Mpox),is a disease of global public health concern,as it does not affect only countries in western and central Africa.AIM To assess Burundi healthcare workers(HCWs)s’level of knowledge and confidence in the diagnosis and management of Mpox.METHODS We conducted a cross-sectional study via an online survey designed mainly from the World Health Organization course distributed among Burundi HCWs from June-July 2023.The questionnaire comprises 8 socioprofessional-related questions,22 questions about Mpox disease knowledge,and 3 questions to assess confidence in Mpox diagnosis and management.The data were analyzed via SPSS software version 25.0.A P value<0.05 was considered to indicate statistical significance.RESULTS The study sample comprised 471 HCWs who were mainly medical doctors(63.9%)and nurses(30.1%).None of the 22 questions concerning Mpox knowledge had at least 50%correct responses.A very low number of HCWs(17.4%)knew that Mpox has a vaccine.The confidence level to diagnose(21.20%),treat(18.00%)or prevent(23.30%)Mpox was low among HCWs.The confidence level in the diagnosis of Mpox was associated with the HCWs’age(P value=0.009),sex(P value<0.001),work experience(P value=0.002),and residence(P value<0.001).The confidence level to treat Mpox was significantly associated with the HCWs’age(P value=0.050),sex(P value<0.001),education(P value=0.033)and occupation(P value=0.005).The confidence level to prevent Mpox was associated with the HCWs’education(P value<0.001),work experience(P value=0.002),residence(P value<0.001)and type of work institution(P value=0.003).CONCLUSION This study revealed that HCWs have the lowest level of knowledge regarding Mpox and a lack of confidence in the ability to diagnose,treat or prevent it.There is an urgent need to organize continuing medical education programs on Mpox epidemiology and preparedness for Burundi HCWs.We encourage future researchers to assess potential hesitancy toward Mpox vaccination and its associated factors. 展开更多

Magnesium(Mg)alloys are ideal candidates for automotive applications due to their high strength to weight ratio,castability,recyclability etc.,however,they lack corrosion and oxidation resistance.Solid-state deposition techniques,such as cold spray,have been demonstrated to enhance their corrosion resistance as it relies on the severe plastic deformation of powder particles upon impact with the substrate to form a metallurgical bond with the substrate and within the coating.At cold sprayed interfaces,a heterogeneous microstructure is formed that includes some porosity,oxides and intermetallics which can significantly affect coating performance.Thus,establishing a direct correlation between the interface microstructure and its properties can aid in designing optimal cold spray parameters.In this study,we investigated the microstructure and mechanical properties of a zinc(Zn)coating deposited on a high pressure die cast(HPDC)AZ91 Mg substrate via high resolution scanning transmission electron microscopy,in situ micro-tensile testing,and finite element method(FEM)modeling.Micro-tensile pillars fabricated using the plasma focused ion beam(PFIB)successfully isolates the coating-substrate interface within the gauge length.The average bond strength of Zn-Mg interface was determined to be∼140 MPa with failure occurring partially at the interface and mostly into the coatings.A detailed microstructural characterization revealed evidence of a strong metallurgical bonding at the Zn-Mg interface and formation of the C14 MgZn_(2)laves phase interlayer resulting in a mixed mode of fracture during the micro-tensile experiments.FEM modeling reveals the stress distribution along the interfaces and suggests that a MgZn_(2)layer thickness between 200–400 nm is optimum to increase the bond strength and minimize the triaxiality.Such a site-specific interfacial analysis with correlative computational modeling provides crucial insight into the overall performance of cold spray interfaces. 展开更多

In a re-examination of the Neogene stratigraphy of the Uşak,Güre,and Selendi basins of western Anatolia,western Turkey,the stratigraphic position of the previously definedİnay Group is revised,which was previously considered to be of the Middle Miocene age.Based on mammalian biochronology and stratigraphic relationships,two sequences are identified,separated by conformable/transitional contacts within the former group:the Middle Miocene Güre Group is composed of the FakılıFormation,characterized by alluvial fan deposits,and the lacustrine Derbent Formation.Radiometric dating of alkaline volcanics laterally associated with Güre Group sediments in the Uşak and Güre basins,and mammalian fossils re-evaluated into the MN5-6 biozones in the Selendi Basin,indicate early Middle Miocene.Considering the stratigraphic relationship with the overlying early Late Mioceneİnay Group as redefined,we estimate that the Güre Group was deposited in the Middle Miocene.Theİnay Group is characterized by a lateral-vertical transition from alluvial deposits of the Ahmetler Formation to the overlying lacustrine Ulubey Formation.An MN9-10 fauna,containing deinotheres,was found within the latter formation. 展开更多

The Zagros Basin in southwestern Iran is a significant source of coal,with numerous coal mines operating in the region.Ensuring the stability of coal mines is crucial for safe and efficient mining operations.This study investigates the time-varying response of rocks and roof resistance in coal mines in the Zagros Mountains using a novel approach that combines numerical simulation,relaxation testing,and rock displacement studies.The results show that rocks exhibit significant time-dependent behavior,with changes in rock mechanical properties over time.A comprehensive viscoelastic-plastic model is devel-oped to accurately describe the time-varying strain-softening response of rocks and simulate laboratory tests.The model integrates the Burgers and strain-softening models,simulating stress relaxation curves and rock displacement over time.The study reveals that the rock mass displays significant nonlinear behavior,with changes in rock mechanical properties over time.The findings of this study highlight the importance of considering the time-varying response of rocks and roof resistance in coal mine stability analysis.The results provide valuable insights into the time-dependent behavior of rock mass in coal mines in Iran,which can inform mining practices and mitigate potential hazards.Results in this study can contribute to developing strategies for improving roof stability and reducing the likelihood of roof collapses. 展开更多

High-pressure die cast(HPDC)AZ91 magnesium alloy is widely used in automotive components such as transmission housings and brackets for its excellent strength-to-weight ratio.Zinc-based cold spray coatings can be applied selectively to vulnerable areas to enhance corrosion resistance,minimize galvanic coupling with dissimilar metals,and eliminate the need for full-surface oxide coatings,making the process more efficient and targeted.A comprehensive evaluation of 16 combinations of nitrogen carrier gas temperatures and pressures led to the identification of an optimal range of process parameters,yielding Zn coatings with porosity<0.5% by area,wear rates reduced by a factor of two compared to uncoated AZ91,and adhesion strengths up to 35 MPa.The enhanced mechanical performance of the coating is attributed to the low porosity and the formation of a metallurgical bond at the coating-substrate interface.Corrosion studies using macroscale potentiodynamic polarization(PDP)and electrochemical impedance spectroscopy(EIS)revealed a significant decrease in corrosion rate and a shift to more noble corrosion potentials(ZCP)for coated substrates.Furthermore,the Zn cold-sprayed samples exhibited significantly lower corrosioninduced evolved hydrogen content compared to the base AZ91 substrate and AZ91 coated with industrial coatings,demonstrating that the Zn layer effectively protects the substrate from the corrosive environment.Overall,cold spray Zn coatings significantly improve the mechanical and corrosion performance of AZ91 Mg alloys,addressing key material challenges and enabling their broader use in automotive applications. 展开更多

This study was conducted at Fafan Research Center, Golajo research site to evaluate the effect of Moringa stenopetala and pigeon pea leaf supplementation on growth performance of short-eared Somali goat breed. A total of fifteen yearling indigenous short-eared Somali goat breeds with an initial weight of 15.2 ± 0.30 kg were assigned to three treatment groups using completely randomized design. Pigeon pea (Pp) and Moringa stenopetala (MS) feeds were formulated using 0%, 5%, and 10% inclusion levels of MSLM and PPLM as experimental diets, respectively. The feed of the experiment was prepared in two levels (2 kg of Moringa stenopetala and 2 kg of pigeon pea) and was supplemented to experimental animals in treatments one and two, respectively. The average e initial body weight of selected male goats was 18.82 ± 0.37, 18.8 ± 0.37 and 17.8 ± 0.37 kg under treatment groups T1, T2 and control respectively. Data was analyzed using general linear model (GLM) procedure of SAS computer package Version 9.0 (SAS, 2002). The final weights gain (FWG) of goats on T1 and T2 of experimental group was significantly (P 0.05) the final weight gain of goat supplemented on Moringa stenopetala (T1) and pigeon pea levels (T2). The mean average weight gains (AWG) obtained from the supplemented group in this study were 7.50 ± 0.37 and 7.82 ± 0.37 kg for T1 and T2, whereas mean weight gains for un-supplemented goats were found to be 6.26 ± 0.37 kg. Feeding of dried Moringa stenopetala and pigeon pea leaves mixture improved body weights and average daily body weight gain without affecting feed intake and overall health of Somali goat breed. As Moringa stenopetala and pigeon pea leaves are rich nitrogen/protein source, they can be used effectively as substitute for conventional concentrate in the diet of growing goats at small holder farmer’s level where they can be grown in abundance. Therefore, for higher quality of forage and higher total DM yield for animal feeding, moringa should be harvested at wider harvesting intervals of at least 6th- to 8th-week intervals. Similarly, for pigeon peas, 4- to 6-week harvesting interval can result in optimum forage as well as feed quality and resulted in better growth performances for Somali short-eared goat breeds. 展开更多

Objective:This article employs a scoping review methodology,integrates knowledge and information about current pediatric nurses'practices and perceptions regarding family-centered care in pediatric settings.Methods:Published articles were retrieved from databases including EBSCO host,PubMed,Springer,Science Direct,Ovid,and CINAHL between 2013 and 2023.Results:The finding shows a better understanding of pediatric nurses'perceptions of family-centered care in association with their clinical settings.However,the evidence indicates that integrating family-centered care components into health care services is difficult and confusing to nurses and is often not implemented in a clinical setting.As evidenced by this review,studies have consistently reported similar results;family-centered care was a good perception and understood by pediatric nurses as a concept but inconsistently used in a daily practice setting.Conclusions:This scoping review is the first phase in promoting a strategic plan to provide educational interventions for pediatric nurses to implement family-centered care in their daily practice settings.It's necessary to recognize pediatric nurses'perceptions and practices concerning family-centered care to provide optimal healthcare services in pediatric settings. 展开更多

Pancreatic cancer is usually associated with a poor prognosis.Surgery is the main curative treatment but pancreatic operations are aggressive and new tools that help clinicians to predict surgical and prognostic outcomes are necessary.Lu et al recently published a retrospective,single centre cohort study evaluating the impact of seven nutritional and inflammatory markers in pancreatic cancer surgical patients:The albumin-to-globulin ratio,prognostic nutritional index(PNI),systemic immune-inflammation index(SII),neutrophil-to-lymphocyte ratio(NLR),platelet-to-lymphocyte ratio(PLR),nutritional risk index,and the geriatric nutritional risk index.A significant correlation was found between the PNI,SII,NLR,and PLR and a hospital discharge of less than 15 days.In a univariable analysis,PNI,SII,NLR and PLR were significantly related to recurrence-free survival and,in a multivariable analysis PNI was associated with overall survival.Various meta-analyses corroborate the results in terms of prognosis but individual studies are discordant on their usefulness.Besides,the cut-off values for these markers vary significantly between studies and there are no clinical trials comparing them to identify the most relevant ones.These are limitations when implementing nutritional and inflammatory biomarkers into clinical practice and further studies are needed in order to answer these questions. 展开更多

Objectives:We systematically reviewed the rational use of medicines using the World Health Organization/International Network of Rational Use of Drugs(WHO/INRUD)core drug use indicators.We also assessed the impact of the coronavirus disease 2019 pandemic and the National Drug Policy(NDP)2005 on the rational use of medicines.Methods:Searches were conducted in PubMed,Scopus,and Google Scholar databases to identify studies that met our eligibility criteria.Assessment of the quality of studies was conducted using the Joanna Briggs Institute criteria for analytical studies.We reported and compared the median values of WHO/INRUD core drug use indicators with standard thresholds.Data were presented with median,interquartile range(IQR),and percentages.MannWhitney and Kruskal-Wallis tests were conducted to assess for statistical significance(P<0.05)across variables.Results:Thirty-one studies were included in the review,comprising 50,931 patient encounters across 268 health facilities.Within prescribing indicators,average number of medicines per patient encountered[3.4(IQR:3.0to 4.0)],percentage of medicines prescribed by generic[50.4%(IQR:47.4%to 65.0%)],percentage of encounters with antibiotic prescribed[40.2%(IQR:30.5%to 52.7%)],percentage of encounters with injection prescribed[18%(IQR:3.2%to 30.0%)]and the percentage of medicines prescribed from essential medicines list[82.0%(IQR:66.4%to 89.3%)].The median percentage of encounters with antibiotics(P=0.04)and the median percentage of medicines prescribed by generics(P=0.03)increased during and after the COVID-19 pandemic.Prescribing indicators were worse in primary and secondary health facilities,with significant differences in the median percentage of encounters with antibiotics(P=0.007)and injections(P=0.0002)across primary,secondary,and tertiary health facilities.There were improvements across all prescribing indicators after the implementation of NDP 2005.Conclusions:Core drug use indicators in Nigerian health facilities deviated from the WHO/INRUD thresholds,with noticeable improvement after the implementation of NDP 2005.More efforts are needed to improve rational drug use in Nigerian hospitals. 展开更多

Quantifying the spatial and temporal distribution of natural groundwater recharge is essential for effective groundwater modeling and sustainable resource management.This paper presents M-RechargeCal,a user-friendly software tool developed to estimate natural groundwater recharge using two widely adopted approaches:the Water Balance(WB)method and Water Table Fluctuation(WTF)method.In the WB approach,the catchment area is divided into seven land-use categories,each representing distinct recharge characteristics.The tool includes eighteen different reference Evapotranspiration(ET0)estimation methods,accommodating varying levels of climatic input data availability.Additional required inputs include crop coefficients for major crops and Curve Numbers(CN)for specific land-use types.The WTF approach considers up to three aquifer layers with different specific yields(for unconfined aquifer)or storage coeffi-cient(for confined aquifer).It also takes into account groundwater withdrawal(draft)and lateral water movement within or outside the aquifer system.M-RechargeCal is process-based and does not require cali-bration.Its performance was evaluated using six datasets from humid-subtropical environments,demon-2 strating reliable results(R=0.867,r=0.93,RE=10.6%,PMARE=9.8,ENS=0.93).The model can be applied to defined hydrological or hydrogeological units such as watersheds,aquifers,or catchments,and can be used to assess the impacts of land-use/land-cover changes on hydrological components.However,it has not yet been tested in arid regions.M-RechargeCal provides modelers and planners with a practical,accessible tool for recharge estimation to support groundwater modeling and water resource planning.The software is available free of charge and can be downloaded from the author's institutional website or obtained by contacting the author via email. 展开更多

BACKGROUND Human beings,by nature,have many expectations that create a feeling of anxiety about the future,but they are endured and long-ranged.They expect to have relationships with others and need to perceive an emotional interest,an interpersonal bond,and sustainment to continue living.Perceiving this link is required for feelings of belongingness,which decreases future anxiety.AIM To investigate the future anxiety and belongingness of young and older adults and determine their relationships.METHODS The study was conducted with 404 volunteer participants.Data were collected using the demographic characteristics from the“Dark Future Scale”and“General Belongingness Scale”.RESULTS The mean age of older adults was 66.76±3.74,while that of younger adults was 36.72±10.12.The average score for“future anxiety”was 18.81±7.59,and for“general belongingness",it was 63.31±1.40.Findings indicated a reverse correlation between future anxiety and belongingness.A significant difference in belonging scores was observed between young and older adults(P=0.016,which is<0.05),whereas no significant difference was found regarding future anxiety scores(P>0.05).CONCLUSION Participants had a moderate level of“future anxiety”and higher“belongingness”.Lower belongingness scores correlated with increased future anxiety.Older adults reported a lower sense of belonging than younger individuals. 展开更多
