The first photometric light curve investigation of the NSVS 8294044,V1023 Her,and V1397 Her binary systems is presented.We used ground-based observations for the NSVS 8294044 system and Transiting Exoplanet Survey Satellite data for V1023 Her and V1397 Her.The primary and secondary times of minima were extracted from al the data,and,by collecting the literature,a new ephemeris was computed for each system.Linear fits for the O-C diagrams were conducted using the Markov Chain Monte Carlo (MCMC) method.Light curve solutions were performed using the PHysics Of Eclipsing BinariEs Python code and the MCMC approach.The systems were found to be contact binary stars based on the fillout factor and mass ratio.V1023 Her showed the O’Connell effect and a cold starspot on the secondary component was required for the light curve solution.The absolute parameters of the system were estimated based on an empirical relationship between orbital period and mass.We presented a new T–M equation based on a sample of 428 contact binary systems and found that our three target systems were in good agreement with the fit.The positions of the systems were also depicted on the M–L,M–R,q–L_(ratio),and M_(tot)–J_(0)diagrams in the logarithmic scales.

Comparing the efficacy and safety of low,medium,and high dosages of selexipag for treating pulmonary hypertension:A systematic review and meta-analysis

Background:The maintenance dosage of selexipag is categorized as low,medium or high.In order to assess the efficacy and safety of different dosages of selexipag for the risk stratification of pulmonary arterial hypertension(PAH),we performed a sys-tematic review and meta-analysis.Methods:Studies assessing PAH risk stratification indices,such as the World Health Organization functional class(WHO-FC),six-minute walk distance(6MWD),N-terminal pro-B-type natriuretic peptide(NT-proBNP)level,right atrial pressure(RAP),cardiac index(CI)and mixed venous oxygen saturation(SvO2),were included.Results:Thirteen studies were included.Selexipag led to improvements in the 6MWD(MD:24.20 m,95%CI:10.74-37.67),NT-proBNP(SMD:-0.41,95%CI:-0.79-0.04),CI(MD:0.47 L/min/m^(2),95%CI:0.17-0.77)and WHO-FC(OR:0.564,95%CI:0.457-0.697).Subgroup analysis demonstrated that all three dosages improved the 6MWD.A moderate dosage led to improvements in the CI(MD:0.30 L/min/m^(2),95%CI:0.15-0.46)and WHO-FC(OR:0.589,95%CI:0.376-0.922).Within 6 months of treatment,only the WHO-FC and CI were significantly improved(OR:0.614,95%CI:0.380-0.993;MD:0.30 L/min/m^(2),95%CI:0.16-0.45,respectively).More than 6 months of treatment significantly improved the 6MWD,WHO-FC and NT-proBNP(MD:40.87 m,95%CI:10.97-70.77;OR:0.557,95%CI:0.440-0.705;SMD:-0.61,95%CI:-1.17-0.05,respectively).Conclusions:Low,medium,and high dosages of selexipag all exhibited good effects.When treatment lasted for more than 6 months,selexipag exerted obvious effects,even in the low-dosage group.This finding is important for guiding individualized treatments.

Gut microbiota modulating therapy for diabetes mellitus should be individualized

In this editorial,we commented on two articles published online in August and September 2024 in the World Journal of Diabetes,which focused on modifying the gut microbiota(GM)to prevent or delay the progression of diabetes mellitus(DM)and DM-related complications.Numerous studies,many of which are animal studies,have indicated the potential role of GM in the pathogenesis of DM.However,the detailed causality and mechanisms between GM and DM have not been fully clarified.Although there have been some reports of a potential role of modifying the GM in treating DM,most lack long-term observations and are not mechanistic.Additionally,the GM and its role in DM might vary among individuals;therefore,GM-targeted interventions should be individualized to realize their therapeutic potential.

Exploration of cardiac rehabilitation nursing for elderly patients with myocardial infarction based on individualized cardiac rehabilitation

BACKGROUND Myocardial infarction is a high-risk condition prevalent among the elderly population,often leading to adverse clinical manifestations such as reduced cardiopulmonary function,anxiety,and depression post-surgery.Consequently,cardiac rehabilitation holds immense importance in mitigating these complications.AIM To evaluate the effect of individualized cardiac rehabilitation on blood pressure variability(BPV)and baroreflex sensitivity(BRS)in elderly patients with myocardial infarction.METHODS A cohort of 74 elderly patients diagnosed with myocardial infarction and admitted to our hospital between January 2021 and January 2022 were subjected to random selection.Subsequently,all patients were divided into two groups,namely the research group(n=37)and the control group(n=37),utilizing the number table method.The control group received conventional drug treatment and nursing guidance intervention,while the study group underwent individualized cardiac rehabilitation in addition to the interventions received by the control group.All patients were continuously intervened for 12 wk,and the BPV of these two groups in the 1st wk(T0),the 4th wk(T1)and the 12th wk(T2)were compared,BRS,changes in cardiopulmonary function measures,and adverse cardiovascular events.RESULTS Of 24 h diastolic BPV,24 h systolic BPV,carbon dioxide ventilation equivalent slope of the research group were lower than those of the control group at T1 and T2,BRS,peak heart rate and systolic blood pressure product,1 min heart rate recovery were higher than those of the control group,and the incidence of adverse events in the research group was lower than that of the control group,the difference was statistically significant(P<0.05).CONCLUSION In this study,we found that after individualized cardiac rehabilitation in elderly patients with myocardial infarction,BPV and BRS can be effectively improved,cardiac function is significantly enhanced,and a better prognosis is obtained.

BSN:The First Light Curve Analysis of the Total Eclipse Binary System EL Tuc

We conducted the first light curve study of the binary star EL Tuc within the Binary Systems of South and North project's framework.The photometric observations were made using standard multiband BVR_cI_c filters at an observatory in Argentina.We presented a new ephemeris for EL Tuc and a linear fit to the O–C diagram,utilizing our extracted times of minima and additional literature.We employed the PHysics Of Eclipsing BinariEs Python code and the Markov chain Monte Carlo approach for the system's light curve analysis.The target system's light curve solution required a cold starspot on the hotter component.We conclude that EL Tuc is a total contact binary system with a low mass ratio of q=0.172±0.002,an orbital inclination of i=83°.74±0°.40,and a fillout factor of f=53.7%±1.6%.We used the P-a relationship and the Gaia Data Release 3 parallax method to determine the absolute parameters of EL Tuc to compare the precision of our results.This system was classified as W-type based on the mass and effective temperature of the companion stars.The positions of the systems were depicted on the M-L,M-R,T-M,and q-Lratiodiagrams.The relationship between the spectroscopic and photometric mass ratios of binaries was discussed.

An Experimental Study on the Effectiveness of Individualized Online Intervention for Mental Health Literacy of Community Residents

Background:Understanding how to improve mental health literacy is conducive to maintaining and promoting individuals’mental health and well-being.However,to date,interventions for mental health literacy primarily depend on traditional education and contact interventions,which have limitations with regard to pertinence and individualization.Artificial intelligence(AI)and big data technology have influenced mental health services to be more intellectual and digital,and they also provide greater technical convenience for individualized interventions for promoting mental health literacy.However,there is relatively little research on the effectiveness of individualized online intervention for mental health literacy in the literature.This study aims to fill this void.To verify whether individualized online intervention can improve the level of mental health literacy.Methods:We conducted a pretest–post-test control experiment.The participants were recruited from a large community located in central China.A total of 152 participants completed the research.We use mixed linear model estimation and paired t-tests to analyze the data.Results:Individualized online intervention can effectively improve the mental health literacy level of participants.Specifically,we found that compared with the control group,the mental health literacy in the experimental group was significantly improved after receiving individualized online intervention.Likewise,the mental health literacy of the control group has also improved after receiving individualized online intervention.In addition,we compared the mental health literacy level of the experimental group at Time 3 to those at Time 2 and found that the mental health literacy level at Time 3 had not decreased one month later.This shows that individualized online intervention was not only momentarily effective,but also had long-term efficacy.Conclusion:This study illustrates that the individualized online intervention has both great momentary and long-term effectiveness in improving community residents’mental health literacy.

BSN:Photometric Light Curve Analysis of Two Contact Binary Systems LS Del and V997 Cyg

The light curve analyses and orbital period variations for two contact binary stars,LS Del and V997 Cyg,are presented in this work which was conducted in the frame of the Binary Systems of South and North project Ground-based photometric observations were performed at two observatories in France.We used the Transiting Exoplanet Survey Satellite(TESS)data for extracting times of minima and light curve analysis of the targe systems.The O-C diagram for both systems displays a parabolic trend.LS Del and V997 Cyg’s orbital periods are increasing at rates of dP/dt=7.20×10^(-08)days yr^(-1)and dP/dt=2.54×10^(-08)days yr^(-1),respectively Therefore,it can be concluded that mass is being transferred from the less massive star to the more massive component with a rate of dM/dt=-1.96×10^(-7)M_(⊙)yr^(-1)for the LS Del system,and dM/dt=-3.83×10^(-7)M_(⊙)yr-1for V997 Cyg.The parameters of a third possible object in the system are also considered.The PHysics Of Eclipsing BinariEs Python code was used to analyze the light curves.The light curve solutions needed a cold starspot due to the asymmetry in the LS Del system’s light curve maxima.The mass ratio fill-out factor,and star temperature all indicate that both systems are contact binary types in this investigation.Two methods were applied to estimate the absolute parameters of the systems:one method relied on the parallax of Gaia DR3,and the other used a P-M relationship.The positions of the systems are also depicted on the M-L,M-R q-L_(ratio),and logM_(tot)-logJ_(0)diagrams.We recommend that further observations and investigations be done on the existence of a fourth body in this system.

Application of patient-derived tumor models in anticancer drug development and individualized medicine

Malignant tumor is the second leading cause of death due to its high incidence, lack of effective treatment and poor prognosis. The evaluation of anticancer drugs used to based on NCI-60 cell line models, but the limited heterogeneity and the divorce from clinical practice of models lead to extremely low success rate of novel anticancer drugs during clinical trials (less than 10%). In recent years, because of the high heterogeneity and human derived tumor matrix, patient-derived tumor models have been gradually applied to the preclinical evaluation of various antitumor drugs, which shows certain advantages in predicting the clinical efficacy of antitumor drugs. Optimize the drug combination through patient-derived tumor models to achieve individualized medicine has gradually become an indispensable strategy in clinical cancer therapy. The current review summarized the development of patient-derived tumor models, characterized the application, advantages and challenges of them in preclinical antitumor drug evaluation and clinical precise medicine, which will provide a scientific basis and novel insights for further basic research, drug development and clinical application.

Intracranial magnetic resonance venography in healthy individuals:normal anatomy and variations of the cerebral venous system

Objective:To evaluate the basic appearance and variation of the venous sinuses and veins in healthy individuals.Methods:Prospectively-recruited healthy volunteers completed a questionnaire and underwent magnetic resonance imaging plus contrast-enhanced magnetic resonance venography(CE-MRV)to measure their sinus diameters.Anatomical variations of cerebral venous sinuses were evaluated.Results:Fifty-eight individuals were included.The mean diameter of the left transverse sinus(LTS)(5.37±1.35 mm)was significantly smaller than that of the right transverse sinus(RTS)(6.65±1.57 mm)(P<0.001),and the average discrepancy was 19.2%.RTS dominance was noted in 55.1%of cases.Four superior sagittal sinus(SSS)anatomical variations were found.Type A was the most common and was present in 43 participants(74.1%).The SSS preferentially drained into the RTS in 32 patients(55.2%),and arachnoid granulation was observed in the transverse sinus(TS)and SSS in patients.According to our reclassification combined with Osborn’s previous research,we found that the SSS commonly drained into the RTS and that the straight sinus(StS)branched into both TSs.Conclusions:A 19%difference between the LTS and RTS provides a threshold for TS lateral dominance instead of a TS abnormality.Clinicians and radiologists should not ignore the influence of acquired pathology when the SSS drains in a non-RTS-dominant manner.Anatomical variations of the torcular herophili are frequent;the most commonly observed was the StS branching into both TSs,with the SSS draining into the RTS.

Research Progress on Individualized Treatment of Splenic Aneurysm

Splenic artery aneurysm has a hidden onset and atypical symptoms.There are various diagnostic methods for splenic aneurysms,among which ultrasound is the first choice for aneurysm screening.The diagnostic rate of CTA and DSA reaches 100%.In clinical practice,it is necessary to integrate medical history,symptoms and signs,and multiple imaging results to improve the diagnostic rate.In terms of treatment plans,both intervention and surgical procedures have their strengths,and the application of intervention will be more extensive.We need to adhere to the principle of individualization and choose a reasonable treatment plan for patients.At present,there are many reports on pregnant women with large splenic aneurysms both domestically and internationally.Some scholars believe that large splenic aneurysms may be related to hormonal imbalances during pregnancy,and the specific pathogenic mechanism will become a hot topic in future research.

Effect of individualized nutrition interventions on clinical outcomes of pregnant women with gestational diabetes mellitus

BACKGROUND Gestational diabetes mellitus(GDM)can lead to excessive pregnancy weight gain(PWG),abnormal glucolipid metabolism,and delayed lactation.Therefore,it is necessary to provide appropriate and effective interventions for pregnant women with GDM.AIM To clarify the effects of individualized nutrition interventions on PWG,glucolipid metabolism,and lactation in pregnant women with GDM.METHODS The study population consisted of 410 pregnant women with GDM who received treatment at the Northern Jiangsu People's Hospital of Jiangsu Provinceand Yangzhou Maternal and Child Health Hospital between December 2020 and December 2022,including 200 who received routine in-terventions[control(Con)group]and 210 who received individualized nutrition interventions[research(Res)group].Data on PWG,glucolipid metabolism[total cholesterol,(TC);triglycerides(TGs);fasting blood glucose(FPG);glycosylated hemoglobin(HbA1c)],lactation time,perinatal complications(cesarean section,premature rupture of membranes,postpartum hemorrhage,and pregnancy-induced hypertension),and neonatal adverse events(premature infants,fetal macrosomia,hypo-glycemia,and respiratory distress syndrome)were collected for comparative analysis.RESULTS The data revealed markedly lower PWG in the Res group vs the Con group,as well as markedly reduced TG,TC,FPG and HbA1c levels after the intervention that were lower than those in the Con group.In addition,obviously earlier lactation and statistically lower incidences of perinatal complications and neonatal adverse events were observed in the Res group.CONCLUSION Individualized nutrition interventions can reduce PWG in pregnant women with GDM,improve their glucolipid metabolism,and promote early lactation,which deserves clinical promotion.

Establishment of organoid models for pancreatic ductal adenocarcinoma and screening of individualized therapy strategy

Background:Patients with pancreatic ductal adenocarcinoma(PDAC)who undergo surgical resection and receive effective chemotherapy have the best chance for longterm survival.Unfortunately,because of the heterogeneity of pancreatic cancer,it is difficult to find a personalized treatment strategy for patients.Organoids are ideal preclinical models for personalized medicine.Therefore,we explore the cultivation conditions and construction methods of PDAC organoid models to screen the individualized therapy strategy.Methods:Fresh PDAC tissues from surgical resection were collected and digested with digestive enzymes;then the tumor cells were embedded in Matrigel with a suitable medium to establish the PDAC organoid models.The genetic stability of the organoids was analyzed using whole exon sequencing;hematoxylin and eosin staining and immunohistochemistry of organoids were performed to analyze their consistency with the pathological morphology of the patient's tumor tissue;After 2 days of organoid culture,we selected four commonly used clinical chemotherapy drugs for single or combined treatment to analyze drug sensitivity.Results:Two cases of PDAC organoid models were successfully established,and the results of their pathological characteristics and exome sequencing were consistent with those of the patient's tumor tissue.Both PDAC organoids showed more sensitivity to gemcitabine and cisplatin,and the combined treatment was more effective than monotherapy.Conclusion:Both organoids better retained the pathological characteristics,genomic stability,and heterogeneity with the original tumor.Individual PDAC organoids exhibited different sensitivities to the same drugs.Thus,this study provided ideal experimental models for screening individualized therapy strategy for patients with PDAC.

BACKGROUND The impact caused by the coronavirus disease 2019(COVID-19)on the Portuguese population has been addressed in areas such as clinical manifestations,frequent comorbidities,and alterations in consumption habits.However,comorbidities like liver conditions and changes concerning the Portuguese population's access to healthcare-related services have received less attention.AIM To(1)Review the impact of COVID-19 on the healthcare system;(2)examine the relationship between liver diseases and COVID-19 in infected individuals;and(3)investigate the situation in the Portuguese population concerning these topics.METHODS For our purposes,we conducted a literature review using specific keywords.RESULTS COVID-19 is frequently associated with liver damage.However,liver injury in COVID-19 individuals is a multifactor-mediated effect.Therefore,it remains unclear whether changes in liver laboratory tests are associated with a worse prognosis in Portuguese individuals with COVID-19.CONCLUSION COVID-19 has impacted healthcare systems in Portugal and other countries;the combination of COVID-19 with liver injury is common.Previous liver damage may represent a risk factor that worsens the prognosis in individuals with COVID-19.

Light Curve Analysis of the AP Dor Binary System using Ground-based and TESS Observations

The short-period eclipsing binary AP Dor’s first in-depth and multiband photometric solutions are presented.We made use of our eight nights of ground-based opportunity at a southern hemisphere observatory,and twelve sectors of TESS observations.We extracted eight and 1322 minima from our observations and TESS,respectively.We suggest a new linear ephemeris based on the trend of orbital period variations using the Markov chain Monte Carlo(MCMC)approach.The PHysics Of Eclipsing BinariEs(PHOEBE)Python code and the MCMC approach were utilized for the light curve analysis.This system did not require a starspot for the light curve solutions.We calculated the absolute parameters of the system by applying the Gaia DR3 parallax method.The orbital angular momentum(J_(0))of AP Dor indicates that this system is located in a region corresponding to contact binaries.According to our results,this system is an overcontact binary system with a mass ratio of 0.584,a fillout factor of 48%,and an inclination of 53°.The positions of component stars in the AP Dor system on the Hertzsprung–Russell diagram are found.

The First Multiband Photometric Light Curve Solutions of the V Gru Binary System from the Southern Hemisphere

The first multiband photometric solutions of the short-period V Gru eclipsing binary from the southern hemisphere are presented in this study.Light curves of the system were observed through BVI filters at the Congarinni Observatory in Australia for 15 nights.In addition to the new ground-based data,we also used the TESS observations in two sectors.We analyzed the light curves of the system using the PHysics Of Eclipsing BinariEs(PHOEBE)2.4.7 version code to achieve the best accordance with the photometric observations.The solutions suggest that V Gru is a near-contact binary system with q=1.302(81)mass ratio,f_(1)=0.010(23),f_(2)=-0.0.009(21),and i=73.45(38).We considered the two hot spots on the hotter and cooler components for the light curve analysis.We extracted the minima times from the light curves based on the Markov Chain Monte Carlo(MCMC)approach.Using our new light curves,TESS,and additional literature minima,we computed the ephemeris of V Gru.The system’s eclipse timing variation trend was determined using the MCMC method.This system is a good and challenging case for future studies.

First Detailed Photometric Investigation on the Nature of Contact Binary System AA Cet

The TESS light curve(LC)of the marginal contact binary A A Cet was analyzed simultaneously with the radial velocity and the orbital period(OP)change of the system was investigated.The physical parameters of the system were obtained by analyzing the LC of A A Cet with the Wilson-Devinney method,and the absolute parameters of the components were calculated using the results obtained.For the components of AA Cet,the masses and radii were calculated as M_(1)=1.39±0.04 M_⊙,M_(2)=0.48±0.02 M_⊙,and R_(1)=1.64±0.03 R_⊙,R_(2)=1.01±0.04 R_⊙,respectively.AA Cet is a marginal contact binary with a temperature difference of 1305 K between its components.A total of 14 eclipse times were obtained from the TESS data and used in the OP analysis together with those collected from the literature.It has been observed that the change in the OP of AA Cet is in the form of a decreasing parabola.Conservative mass transfer between the components has been interpreted as the reason for this change.The OP decrease amount of A A Cet was obtained as dP/dt=0.0062±0.0006 s yr^(-1).and the reason for this decrease was attributed to a 3.3(9)×10^(-8)M_⊙.mass transfer per year from the more massive component to the less massive one.The age of A A Cet has been estimated as 7 Gyr,as the age of contact systems helps us to understand their evolution.

Breast Cancer Treatment (Mastectomy Experiences) May Initiate Individuation Process That Redefines Identities: A Systematic Review

This systematic literature review examines the impact of breast cancer treatment experiences, with a focus on mastectomy, on the psychosocial well-being of women. While previous studies have shown that mastectomy is associated with negative psychological outcomes such as anxiety, depression, and a loss of femininity, a new body of literature suggests that it can also be a catalyst for post-traumatic growth and personal transformation. The article argues that mastectomy experiences can initiate an individuation process that leads to a more empowered sense of self and a higher quality of life. The review identified 25 studies that employed qualitative methods and analyzed data from interviews, focus groups, and surveys. The article discusses the application of Jung’s individuation theory to categorize the experiences of women with breast cancer and links breast cancer diagnosis and treatment to the death-experience stage of the theory. The content highlights the importance of movement, contemplation, and spirituality in the healing process, and how they can help women connect with their bodies and develop a new sense of identity. Additionally, the content discusses the role of spirituality in enhancing growth and healing among indigenous native women patients with breast cancer. Overall, this article provides insights into how breast cancer treatment experiences can shape women’s identity, enhance resilience, and provide opportunities for personal growth and transformation.
