Authors: Chughtai Muhammad Salman , Khalid Yasra , Mushtaque Iqra , Yusrini Lenny , Akhtar Nasreen 
Published: January 2024

Purpose - The present study investigates the intervening mechanism of change self-efficacy between the change-oriented leadership and change-oriented organizational citizenship behaviors relationship. This study also examines the moderating role of proactive personality between change-oriented leadership and change self-efficacy relationship and the moderating role of felt obligation between the relationship of change self-efficacy and change-oriented organizational citizenship behaviors.
Design/methodology/approach - The proposed model was tested using simple random sampling with a time-lagged technique; 394 subordinates and 149 immediate supervisors/managers who were full-time employees of manufacturing sector organizations freely joined the survey process. Through different statistical methods, proposed hypotheses (direct, mediation, and moderation) were analyzed using SPSS v.25, PROCESS-macro, and Smart-PLS.
Findings - The present study reveals that change self-efficacy partially mediates the change-oriented leadership and change-oriented organizational citizenship behaviors relationship. Furthermore, a proactive personality moderates the relationship between change-oriented leadership and change self-efficacy, and felt obligation moderates the change self-efficacy and change-oriented organizational citizenship behaviors link.
Research Limitations/implications - For successful implementation of change strategies, this study highlights the significance of subordinates' extra-role activities, which can be attained using leadership's value in assisting them to build their self-confidence and engage in actions outside their job description. The present also enlightens the worth of personality for improving change self-efficacy and the psychological state, i.e., a sense of responsibility for positive change, which encourages them to show extra-role behaviors.
Originality/value of the results - The present study guides practitioners and policymakers to understand the role of leadership, personality attributes, and psychological states, i.e., self-efficacy and felt obligation for the success of organizational change strategies. Also, leadership enthusiasm during organizational change boosts subordinates' ability to handle challenging situations, which leads to extra-role activities. Subordinates can also successfully adopt and support organizational change strategic planning through motivation, encouragement, and higher self-confidence.

Authors: Ye Zhenbang , Huang Ning , Fu Yongliang , Tian Rongle , Wang Liming , Huang Wenting 
Published: January 2024

Background:Diffuse large B-cell lymphoma (DLBCL) is the predominant type of malignant B-cell lymphoma. Although various treatments have been developed, the limited efficacy calls for more and further exploration of its characteristics.Methods:Datasets from the Gene Expression Omnibus (GEO) database were used for identifying the tumor purity of DLBCL. Survival analysis was employed for analyzing the prognosis of DLBCL patients. Immunohistochemistry was conducted to detect the important factors that influenced the prognosis. Drug-sensitive prediction was performed to evaluate the value of the model.Results:VCAN, CD3G, and C1QB were identified as three key genes that impacted the outcome of DLBCL patients both in GEO datasets and samples from our center. Among them, VCAN and CD3G+ T cells were correlated with favorable prognosis, and C1QB was correlated with worse prognosis. The ratio of CD68 + macrophages and CD8 + T cells was associated with better prognosis. In addition, CD3G+T cells ratio was significantly correlated with CD68 + macrophages, CD4 + T cells, and CD8 +T cells ratio, indicating it could play an important role in the anti-tumor immunity in DLBCL. The riskScore model constructed based on the RNASeq data of VCAN, C1QB, and CD3G work well in predicting the prognosis and drug sensitivity.Conclusions:VCAN, CD3G, and C1QB were three key genes that influenced the tumor purity of DLBCL, and could also exert certain impact on drug sensitivity and prognosis of DLBCL patients.Funding:This work is supported by the Shenzhen High-level Hospital Construction Fund and CAMS Innovation Fund for Medical Sciences (CIFMS) (2022-I2M-C&T-B-062).

Published: January 2024

Abstract: Market garden crops constitutes an important source of food and is one of the most income-generating activities in Côte d'Ivoire. In the Abidjan district, several market gardening sites are located near illegal landfill sites, therefore representing a danger for consumers.
Aims: This study was carried out to map these different sites, inventory the plant species cultivated and characterize the cultivation practices with a view to highlighting the constraints and identifying prospects for improvement.
Methodology: Semi-structured individual interviews were carried out in 4 communes of Abidjan (Abobo, Bingerville, Cocody and Port-bouët) to collect information from 400 residents including 280 men and 120 women. The statistical analysis of the survey results was carried out using Google Form and Excel software.
Results: The results revealed six (6) market garden sites with landfills distributed in four (4) different communes (Abobo - Akeikoi village; Bingerville - Bingerack city; Cocody - M'pouto village and M'badon village; Port-bouët - 4th bima and Mafiblé village). Thirteen (13) market garden species which are divided into eight families. Lettuce and basil are grown on all identified sites and represent the most cultivated species (40%). Market garden crops is practiced by young people aged 10 to 30 (70%) with a relatively low level of education. Pests (insects, rodents, fungi) and heavy metals from illegal dumps constitute the main obstacles to production and are vectors of frequent diseases.
Conclusion: It would be wise to adopt an integration policy for market gardening, in urban development plans, and to combat the proliferation of uncontrolled landfill sites, this will help to improve the quality and yield of market garden crops in Abidjan.

Aims: to analyze and map the international scientific production of Nursing on Alzheimer's Disease, in the historical series from January 2016 to November 2021.
Methodology: This is a study of a basic nature, with a mixed approach and under the light of procedures methodological, configures itself as research of the Bibliometric type. Data collection took place in July 2021 through institutional online access to the CAPES Journal Portal, in the Scopus (Elsevier) database, using the combination of the following MESHs: "Alzheimer's disease", "Elderly", "Very Old" and “Nursing”, all mediated by the Boolean operators “AND” and/or “OR”. The final sampling resulted in 189 publications.
Results: n=189 publications were identified, distributed in n=66 journals, divided into 30 countries. It was evidenced that the year 2016 has the highest number of publications with n=44 (23.28%), followed by the year 2017 with n=42 (22.22%) articles and 2018 with n=38 (20.11) %) articles, these being the years with the highest number of publications. From the analysis of the included studies, it was observed that the publications that made up this Bibliometric review addressed 4 large distinct thematic groups: 1) Difficulties encountered by family caregivers with elderly people with Alzheimer's disease; 2) Nursing in Home Care for the Elderly with Alzheimer's Disease in Palliative Care; 3) Behaviors Observed in Elderly People with Severe Dementia and 4) Quality of Life in Elderly People with Cognitive Disabilities.
Conclusion: Despite the few publications in the database, it is observed that the publications are at a high level of quality when we look at the evaluation metrics of the selected studies. It can be seen that the main research centers on the subject are in countries such as France, Japan, the United Kingdom and the Netherlands. Furthermore, the study demonstrated the various gaps that need to be addressed and deepened on the subject that require scientific investigation.
Parameter Estimation for Partially Complete Time and Type of Failure Data
Authors: Kundu Debasis 
Published: April 2004

AbstractThe theory of competing risks has been developed to asses a specific risk in presence of other risk factors. In this paper we consider the parametric estimation of different failure modes under partially complete time and type of failure data using latent failure times and cause specific hazard functions models. Uniformly minimum variance unbiased estimators and maximum likelihood estimators are obtained when latent failure times and cause specific hazard functions are exponentially distributed. We also consider the case when they follow Weibull distributions. One data set is used to illustrate the proposed techniques. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A Mixed Model Approach to Discriminant Analysis with Longitudinal Data
Authors: Wernecke K.‐D. , Kalb G. , Schink T. , Wegner B. 
Published: April 2004

AbstractIn medical diagnostics data are often characterized by repeated observations on the same subject (patient), particularly in form of time series, dose‐response curves etc. If the aim is an individual allocation of patients into one of different groups (diagnoses), a discriminant analysis has to be applied. In a first attempt, Tomasko et al., 1999 [5] modified the well‐known linear discriminant analysis using the mixed model MANOVA for the estimation of fixed effects and for a determination of various structures of covariance matrices, including unstructured, compound symmetry, and autoregressive of order 1. We extended that approach by a random subject effect (Azzalani, 1995 [1]), validated error estimations, and cross‐validated feature selection (Wernecke, 2002 [9]). In this paper, we complete the investigations of the new method with a cross‐validated selection of the adequate model (covariance structure) and extensive Monte‐Carlo simulations. An application to contrast‐enhanced breast MRI signals in a multicenter study is also given. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Empirical models of cadmium accumulation in maize, rye grass and soya bean plants
Authors: Tudoreanu Liliana , Phillips Clive JC 
Published: April 2004

AbstractLinear regression of published values for soil parameters and cadmium concentrations in plant tissues offers the opportunity to develop uptake coefficients that can be applied in a wide range of circumstances. A widespread literature search was performed which identified publications from the last 20 years containing information on cadmium uptake by maize and rye grass plants. After discarding experiments with inadequate data or parameters, 10 and eight papers were chosen for maize and rye grass respectively to develop linear models that related pH and cadmium concentration in the growth media (soil in pots or nutrient solution) to cadmium concentration in maize or rye grass plants (excluding roots). Cadmium concentrations in both maize and rye grass were positively correlated with soil cadmium concentration, and in the case of maize negatively correlated with soil pH. They were also negatively correlated with the product of soil cadmium concentration and soil pH, demonstrating that at high soil cadmium concentration a high soil pH reduced plant cadmium concentration. A further model of data generated from one experiment with soya beans demonstrated that other factors, such as soil temperature, can have a major influence on uptake.

Authors: Taleb‐Contini S. H. , Salvador M. J. , Balanco J. M. F. , Albuquerque S. , de Oliveira D. C. R. 
Published: April 2004

AbstractPhytochemical study of Chromolaena hirsuta (Hook. & Arn.) R. King & H. Robinson crude extract (collected in Furnas, MG‐Brasil) produced ﬁfteen ﬂavonoids, two triterpenes and ﬁve steroids. IR, UV, 1H and 13C NMR spectroscopy and GC analysis were used for the identiﬁcation of these compounds.The dichloromethanic and ethanolic crude extracts (ﬂowers and leaves) and six ﬂavonoids isolated from this specie have been assayed for antiprotozoal activity against tripomastigote forms of Trypanosoma cruzi and promastigote forms of Leishmania amazonensis. The crude extracts signiﬁcantly reduced the viability of T. cruzi and Leishmania amazonensis, and the six ﬂavonoids showed considerable antiproliferative effect of development of two parasites evaluated. This is the ﬁrst report of antiprotozoal activity of extracts of C. hirsuta. Copyright © 2004 John Wiley & Sons, Ltd.
Using Digest to implement the pathway participation method for detecting inﬂuential system structure
Authors: Mojtahedzadeh Mohammad , Andersen David , Richardson George P. 
Published: April 2004

AbstractThis article brieﬂy deﬁnes and describes the pathway participation metric (PPM), a mathematical calculation that can help to identify the linkages between the structure and behavior of a dynamic system. PPM has been implemented in an experimental piece of software called Digest, which we then present. Digest is not a simulation language, but rather a companion to any commercial system dynamics package, which accepts a text version of a simulation model and performs post formulation analysis of the model. Digest detects and displays which feedback loops are most inﬂuential in explaining a selected pattern of behavior in a model. Output from a sample Digest run is presented and described.

Resection of Peritoneal Implantation of Hepatocellular Carcinoma after Hepatic Resection: Risk Factors and Prognostic Analysis
Authors: Yeh Chun‐Nan , Chen Miin‐Fu 
Published: April 2004

Abstract.Peritoneal implantation from hepatocellular carcinoma (HCC) after hepatic resection is infrequent, and information on risk factors and long‐term survival of such patients is lacking. The clinicopathologic features and risk factors of 16 HCC patients after hepatic resection who developed peritoneal implantation from an HCC and the prognosis after surgical resection of these HCC implants were assessed. The clinical features of 16 HCC patients after hepatic resection undergoing resection of peritoneal HCC implants (P‐HCC) from 1986 and 2000 were reviewed. The clinical features and outcomes of 195 HCC patients undergoing hepatectomy without recurrence (NR‐HCC) were used for comparison. During 1986 and 2000 a total of 749 HCC patients underwent hepatic resection. Of these 749 patients, 465 (62.1%) had HCC recurrence after hepatic resection during the follow‐up period (median 26 months). Of the 465 patients, 26 (5.6%) developed peritoneal implants, and 16 of them underwent resection. Multivariate logistic regression analysis revealed that a high α‐fetoprotein (AFP) level and capsular invasion by the tumor cells may predispose posthepatectomy patients to peritoneal implantation from their HCCs. The overall survival of the P‐HCC patients after peritoneal implant resection was similar to that of the NR‐HCC patients. An elevated AFP level might be regarded as a significant prognostic factor for poor overall survival (p = 0.0577) after resection of peritoneal implants from HCCs. Peritoneal implantation occurs infrequently in posthepatectomy patients with an HCC. Elevated AFP values and capsule invasion by tumor cells may predispose posthepatectomy patients to peritoneal implantation from HCCs. Surgical resection of peritoneal implants from HCCs may prolong survival in selected patients. Elevated AFP levels may be regarded as a possibly significant prognostic factor for poor overall survival after resection of peritoneal HCC implants.

Objective The potential contribution of psychological and anatomical changes to sexual dysfunction following hysterectomy is not clear. Radical hysterectomy for cervical cancer causes surgical damage to the autonomic nerves which are responsible for the increased vaginal blood flow during sexual arousal. Simple hysterectomy causes more limited nerve disruption. Photoplethysmographic assessment of vaginal pulse amplitude objectively measures vaginal blood flow during sexual arousal. We hypothesised that damage of the autonomic nerves results in a disrupted vaginal blood flow response during sexual stimulation.Design Between‐groups comparison of vaginal pulse amplitude.Setting University hospital.Sample Twelve women with a history of radical hysterectomy, 12 women with a history of simple abdomonal hysterectomy and 17 aged‐matched controls.Methods Photoplethysmographic assessment of vaginal pulse amplitude during sexual stimulation by erotic films. Self‐reported ratings of subjective sexual arousal were collected after each erotic stimulus condition.Main outcome measure Maximum vaginal pulse amplitude.Results Maximum vaginal pulse amplitude differed between the three groups (P= 0.043). Women with a history of radical hysterectomy had a lower response than controls (P= 0.015). Women in the radical hysterectomy group and controls reported an equally strong subjective arousal. Women with a history of simple hysterectomy showed an intermediate maximum vaginal pulse amplitude.Conclusions Radical hysterectomy seems associated with a disturbed vaginal blood flow response during sexual arousal. This cannot be explained solely by uteric extirpation, since it was not observed to the same extent after simple hysterectomy, but might be related to a denervation of the vagina which increases with increasing radicality of surgery.
Nursing Management of Second Stage Labor
Authors: McKeon Valerie A. , O'Reilly Maureen 
Published: April 2004

Abstract(1) Despite considerable research into nursing management of second stage labor, traditional approaches continue to predominate. Women are still encouraged to deliver in a recumbent position using sustained, closed‐glottis pushing. Current research suggests that utilizing an upright position with pushing that is open glottis and complementary with the involuntary bearing‐down reflex produces good maternal/fetal outcomes. Issues such as position, second stage phases, and bearing‐down techniques are discussed in view of recent research findings. Gaps in knowledge are identified and practice implications are clearly defined. Now is the time to apply research‐based knowledge to nursing management of second stage labor.
Sibling Visitation: Research Implications for Pediatric and Neonatal Patients
Authors: Andrade Tonya M. 
Published: April 2004

Abstract(1) Little research has been published addressing the effects of sibling visitation on the nonhospitalized sibling. This integrative review synthesizes the studies and has been summarized to include findings, gaps, and limitations. The majority of research regarding the benefits of sibling visitation has come from the Neonatal Intensive Care Unit (NICU). This summary, however, includes one study set in the NICU, one set in an adult ICU, two on a postpartum floor, and one based on siblings of pediatric patients. Findings indicate that children who visited their sibling exhibited improved activity levels, spoke more about their siblings, and did not increase the frequency of infectious signs and symptoms in the newborn siblings. Implications for research utilization include the identified benefits and minimal risks of sibling visitation. Nurses have a vital role initiating and implementing policies that incorporate more liberal sibling visitation.
