Purpose:Interdisciplinary research has become a critical approach to addressing complex societal,economic,technological,and environmental challenges,driving innovation and integrating scientific knowledge.While interdisciplinarity indicators are widely used to evaluate research performance,the impact of classification granularity on these assessments remains underexplored.Design/methodology/approach:This study investigates how different levels of classification granularity-macro,meso,and micro-affect the evaluation of interdisciplinarity in research institutes.Using a dataset of 262 institutes from four major German non-university organizations(FHG,HGF,MPG,WGL)from 2018 to 2022,we examine inconsistencies in interdisciplinarity across levels,analyze ranking changes,and explore the influence of institutional fields and research focus(applied vs.basic).Findings:Our findings reveal significant inconsistencies in interdisciplinarity across classification levels,with rankings varying substantially.Notably,the Fraunhofer Society(FHG),which performs well at the macro level,experiences significant ranking declines at meso and micro levels.Normalizing interdisciplinarity by research field confirmed that these declines persist.The research focus of institutes,whether applied,basic,or mixed,does not significantly explain the observed ranking dynamics.Research limitations:This study has only considered the publication-based dimension of institutional interdisciplinarity and has not explored other aspects.Practical implications:The findings provide insights for policymakers,research managers,and scholars to better interpret interdisciplinarity metrics and support interdisciplinary research effectively.Originality/value:This study underscores the critical role of classification granularity in interdisciplinarity assessment and emphasizes the need for standardized approaches to ensure robust and fair evaluations. 展开更多

Introduction: Malignant sylvian infarction (MSI) is a type of ischemic stroke (ICS) usually affecting the entire territory of the middle cerebral artery (MCA) associated with significant cerebral edema and a mass. It represents about 10% of all AICs, with a mortality of up to 80%. The objectives of our study were to describe the sociodemographic profile and the main clinical manifestations and identify the prognostic factors of ISM. Material and Methods: We conducted a retrospective descriptive study over a 2-year period. It included patients hospitalized for cerebral infarction involving 2/3 of the ACM territory with a NIHSS score ≥ 17 and/or a Glasgow score Results: We collected 223 patients hospitalized for ischemic stroke, of whom 21 patients (9.4%) presented with ISM. The mean age was 57.43 ± 24.24 years with a male predominance (52.4%). The mean admission time was 47 ± 0.87 hours, and hemiplegia was the frequent neurological sign (85.7%). HBP was the common cardiovascular risk factor (76.2%). The mean NIHSS at admission was 18.38 ± 12.29. Respiratory distress (p-value = 0.00015), aspiration pneumonia (p-value = 0.015) and brain herniation (p-value = 0.014) were the main complications associated with mortality. Conclusion: ISM is associated with poor prognosis in the absence of surgical treatment. Respiratory distress, aspiration pneumonia and brain herniation are associated with high mortality. 展开更多

The prompt fission neutron spectrum(PFNS)is a key nuclear data quantity that is of particular interest and plays a crucial role in understanding and modeling fission processes.An array comprising 48 liquid scintillation detectors and a parallelplate avalanche counter(PPAC)was developed at the China Institute of Atomic Energy(CIAE)to measure the PFNS of actinide nuclei.Efficiency and energy calibrations were performed for all the liquid scintillators,and their efficiencies were consistently found to be better than 5%.The time resolutions of the PPAC and liquid scintillators were measured to be 1.08 ns and 1.16 ns using~(252)Cf and~(207)Bi sources,respectively.The pulse shape discrimination of the liquid scintillator was utilized to identify neutron andγsignals on an event-by-event basis,and the figure of merit was deduced as 1.12 at a 200 ke Vee threshold.The contribution to the PFNS from multiple scattered neutrons was evaluated via Geant4 simulations,and those originating from the environment were found to be comparable to the crosstalk between the detectors.The neutron efficiency of the entire detection array was calibrated using a~(252)Cf spontaneous fission source and was demonstrated to be consistent with the Geant4 simulation results,which verified the reliability of the detection array. 展开更多

Introduction: Pain has been defined for more than 20 years by the International Association for the Study of Pain (IASP) as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. It has been recognized as a feature of Parkinson’s disease (PD) since the first descriptions of the disease. Material and Methods: This was a prospective descriptive study lasting six (06) months from November 1, 2023 to April 30, 2024. We included all patients diagnosed with PD and who had pain. Sociodemographic, clinical, paraclinical and therapeutic data were evaluated for each patient. Results: We identified a sample of 62 Parkinson’s patients, of whom 52 patients or 85.2% had associated pain. We noted a male predominance (38M/14F) and a sex ratio of 2.71. Musculoskeletal pain was common in 80% of our respondents. WHO level I, antidepressants and background treatment for KD were the most prescribed molecules. Conclusion: Our study shows a frequency of pain in PD. However, musculoskeletal pain is the most frequently encountered type of pain in PD patients. WHO step I analgesics, antidepressants and background treatment of KD were the main prescriptions in our study. 展开更多

BACKGROUND Bile spillage occurs more frequently in patients with incidental gallbladder carcinoma(iGBC)and may be associated with poor survival due to presumed high risk of peritoneal seeding.AIM To investigate the impact of bile spillage during primary surgery on the survival of patients with iGBC.METHODS Medical records of patients with iGBC diagnosed between 2000 and 2019 in 27 Dutch secondary centers and 5 tertiary centers were retrospectively reviewed.Patient medical records were assessed.Predictors for overall survival(OS)were determined using multivariable Cox regression.RESULTS Of the 346 included patients with iGBC,138(39.9%)had bile spillage,which was associated with higher American Society of Anesthesiologists classification(P=0.020),cholecystitis(P<0.001),higher tumor stage(P=0.005),and non-radical resection(P<0.001).Bile spillage was associated with poor OS[hazard ratio=1.97,95%confidence interval(CI):1.48-2.63,P<0.001]with a median OS of 12 months(95%CI:7-18 months)vs 34 months(95%CI:14-55 months,P<0.001).In multivariable analysis,spillage was not an independent prognostic factor for survival(hazard ratio=1.21,95%CI:0.84-1.74,P=0.313).CONCLUSION Although bile spillage correlates with prognostic factors,it lacks independent prognostic significance for survival.Patients with an indication for additional treatment should be promptly referred to a specialized hepatopancreatobiliary center,irrespective of whether bile spillage has occurred. 展开更多

Introduction: Vitamin D plays a key role in phosphocalcic metabolism, in normal functioning of the immune system and in the prevention of certain forms of cancer. Systematic vitamin D supplementation has been implemented in most Western countries, which has drastically reduced the prevalence of rickets. In Senegal, a country with enough sunshine, no large-scale data exists on vitamin D deficiency in children. In addition, there are no guidelines from the Ministry of Health and Social Action (MoHSA) on vitamin D supplementation. Our objective was to determine the prevalence of vitamin D deficiency in children aged 6 to 59 months and to analyze the factors associated with it at the Institute of Social Pediatrics in Pikine-Guédiawaye, a suburb of Dakar. Patients and Methods: This was a prospective, descriptive and analytical cross-sectional study over a 3-month period (from January to March 2024) at the Institute of Social Pediatric (IPS) of Pikine-Guédiawaye. The study population consisted of all children aged 6 to 59 months free from any acute or chronic pathology, whose parents had agreed to answer the questionnaires after having consented and signed the consent and children who had had a sample taken for vitamin D dosage. Results: We included 102 children, 35 of whom had vitamin D deficiency, i.e. a prevalence of 34.31% with a slight male predominance (sex ratio 1.05). Infants aged 13 - 24 months were more affected (41.67%), but the difference was not statistically significant (p-value = 0.385). Patients with acute malnutrition had a significantly higher prevalence of vitamin D deficiency (54.17% of cases versus 28.38%) in those without acute malnutrition (p = 0.02). On the other hand, chronic malnutrition, underweight and diversification foods were not significantly associated with vitamin D deficiency (p of 0.60, 0.42 and 0.09 respectively). Conclusion: Vitamin deficiency affects one-third of apparently healthy children under 5 and this deficiency has no significant relationship with diversification foods. This suggests that the observed vitamin D deficiencies are less related to diet than to lack of sun exposure. 展开更多

AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. 展开更多
