Authors: Schoephoerster Jamee , Matas Arthur , Jackson Scott , Pruett Timothy L. , Finger Erik , Kandaswamy Raja , Dunn Ty , Kirchner Varvara , Anderson J. Kyle , Humphreville Vanessa 
Published: February 2023

Background.
Laparoscopic donor nephrectomy (LDN) offers advantages to the donor. The reported incidence of testicular pain after LDN varies in the literature ranging from 3% to 55%.

Methods.
A survey was sent to 322 male LDN patients who donated from February 5, 2009, to February 5, 2019. The survey assessed if the donor had testicular pain or saw an additional medical professional after donation.

Results.
Of the 322 surveyed, 147 (46%) responses were received. Of those who had a left nephrectomy, 39% had testicular pain; 23.8% of those patients had testicular swelling in addition. Of those who had pain, laterality of kidney donated did not impact if the patient had pain, pain onset, pain level, or pain duration. Of those who donated their right kidney, 35% had testicular pain, and 16.7% of those patients reported testicular swelling in addition. Twenty-seven symptomatic patients sought additional medical care for the testicular symptoms postdonation. Seven (25%) had hydroceles, 2 (7%) had testicular cysts, 1 had a urinary tract infection, and 16 (59%) had reassurance or no additional procedures provided.

Conclusions.
Our results suggest that orchialgia is not as uncommon as previously thought and may be one of the most common minor complications experienced by male donors.

Authors: Shakibaei Fereshteh , Jelvani Danial 
Published: February 2023

ObjectivesThe present research aimed to evaluate the effect of addingl-carnitine to risperidone in treating children and adolescents with autism spectrum disorder (ASD).MethodsIn this randomized controlled clinical trial study, 50 ASD children and adolescents were divided into 2 groups: those receivingl-carnitine and risperidone (n = 25) and those receiving placebo and risperidone (n = 25). Treatment continued for 8 weeks, and participants were assessed at the beginning of the study, in the fourth and eighth weeks, by the Aberrant Behavior Checklist (ABC).Resultsl-Carnitine add-on therapy reduced the scores of total ABC and subscales of restlessness, lethargy and social isolation, stereotypic behavior, and inappropriate speech at weeks 4 and 8. There was a significant difference between the 2 groups in the score of total ABC and subscale of lethargy and social isolation.ConclusionsAccording to the present study, addingl-carnitine to risperidone improves ASD symptoms.
Dispelling Dogma: American Association for Surgery of Trauma Prospective, Multicenter Trial of Index vs Delayed Fasciotomy after Extremity Trauma
Authors: Keating Jane J , Klingensmith Nathan , Moren Alexis M , Skarupa David J , Loria Anthony , Maher Zoe , Moore Sarah A , Smith Michael C , Seamon Mark J ,   Fasciotomy Group Investigators
Published: February 2023

Background:
Surgical dogma states that “if you think about doing a fasciotomy, you do it,” yet the outcome benefit to this approach remains unclear. We hypothesized that early fasciotomy during index operative procedures for extremity vascular trauma would be associated with improved patient outcomes.

Study Design:
This prospective, observational multicenter (17 Level-I, one Level-II) analysis included patients ≥15 years-old with extremity vascular injuries requiring operative management. Clinical variables were analyzed with respect to fasciotomy timing for correlation with outcomes including muscle necrosis and limb amputation. Associated variables (p<0.05) were input into multivariable logistic regression models evaluating these endpoints.

Results:
Of 436 study patients, most were males (87%) with penetrating (57%) lower extremity (77%) arterial (73%) vein (40%) and bony (53%) injuries with prolonged hospital length of stay (11 days). Patients who had index fasciotomy (66%) were compared to those who did not (34%) and no differences were appreciated with respect to age, initial SBP, tourniquet time, “hard” signs of vascular injury, MTP activation, or ISS (all p<0.05). Of the 289 patients who underwent index fasciotomy, 49% were prophylactic, 11% developed muscle necrosis, 4% required an additional fasciotomy and 8% required amputation while only 28 of 147 (19%) required delayed fasciotomy in those without index fasciotomy. Importantly, forgoing index fasciotomy did not correlate (p>0.05) with additional muscle necrosis or amputation risk in the delayed fasciotomy group. After controlling for confounders, index surgery fasciotomy was not associated with either muscle necrosis or limb salvage in multivariable models.

Conclusions:
Routine, index operation fasciotomy failed to demonstrate an outcome benefit in this prospective, multicenter analysis. Our data suggests that a careful observation and fasciotomy when needed approach may limit unnecessary surgery and its resulting morbidity in extremity vascular trauma patients.

Published: February 2023

SummaryImmune checkpoint inhibitors (ICIs) are a breakthrough in oncology treatment, and studies of screening predictive biomarkers of ICIs are emerging. We developed a web server named IMPACT (http://impact.brbiotech.com/) to thoroughly explore immunotherapeutic predictive or prognostic biomarkers. IMPACT contains a large dataset of 6,276 patients treated with ICIs and integrates 11 well-designed function modules, enabling an in-depth solution for biomarkers exploration. Compared with the existing tools, IMPACT was implemented with one exclusive module for interaction analysis and several optimized conventional functions for discovering novel biomarkers. Specifically, the interaction analysis of biomarker-treatment effect is essential to determine whether a biomarker is predictive and/or prognostic for ICIs. Moreover, several optimized functions allow complicated biomarker exploration, including customized selections of variant types in more detail, automatically screening meaningful co-mutations among multiple genes, and selecting cut-off values for gene expression biomarkers. In summary, IMPACT is a comprehensive analysis resource to facilitate biomarker research of ICIs.
Measurement and analysis of vibration characteristics of nanocrystalline magnetic core under symmetrical/asymmetrical waveforms
Authors: Chen Bin , Xi Binsheng , Wan Nina , Wang Shuaibing , Tang Bo 
Published: February 2023

Purpose
Because the nanocrystalline core is widely used in power electronic equipment, and the excitation waveform of its working mode is complex, the vibration at medium and high frequencies cannot be ignored. Therefore, this study aims to study the vibration mechanism of nanocrystalline strip and the vibration characteristics of nanocrystalline magnetic ring under different excitation waveforms.

Design/methodology/approach
First, the electromagnetic vibration mechanism between nanocrystalline strips is analyzed by finite element analysis, and the force of the magnetic ring with and without air gap is compared and analyzed. Then, the vibration of nanocrystalline magnetic ring under different excitation waveforms such as sine wave, triangular wave, symmetric rectangular wave and asymmetric rectangular wave is analyzed by experimental method. The acceleration time domain waveform measured by the experiment is analyzed by fast Fourier transform, and the vibration is analyzed according to the spectrum.

Findings
Because of the increase of magnetic flux leakage, the volume force density and the Maxwell force on the surface of the nanocrystalline magnetic ring will increase after the air gap is opened, resulting in the intensification of vibration. Under symmetric/asymmetric rectangular wave excitation, the vibration acceleration varies with the duty cycle. Due to the influence of harmonic excitation, the relationship between the main frequency of vibration and the excitation frequency is not two times, and its multiple decreases with the increase of excitation frequency.

Originality/value
The research and analysis of this paper can promote the application of new magnetic materials in electrical equipment in small and medium-sized and medium- to high-frequency fields.
Non-linear dynamics and stability of rolling bearing–axle coupling system of a railway freight wagon with the change of axle rotating speed
Authors: Juping Yang , Wang Junguo , Yongxiang Zhao 
Published: February 2023

PurposeThe purpose of this paper is to investigate the non-linear characteristics and stability of the rolling bearing–axle coupling system under the excitation of the axle/wheel speed of railway freight cars, so as to put forward a rationale for judging the vibration law and running stability of railway freight wagon.Design/methodology/approachConsidering the effects of eccentric force of the railway wagon axle, the non-linear resistance of the wagon and non-linear support forces of axle box rolling bearings, a centralized mass model of rolling bearing-axle coupling system of railway freight wagon is presented on the basis of the theory of rotor dynamics and non-linear dynamics. Then the Runge-Kutta method is adopted to solve the non-linear response of the proposed system, and numerical simulation including bifurcation diagrams, axis trajectory curves, phase plane plots, Poincaré sections and amplitude spectras are analysed when the axle rotating speed is changed. Meantime, the relation curve between Floquet multiplier and axle rotating speed, which affects the stability of coupling system, is plotted by numerical method based on the Floquet theory and method.FindingsThe simulation results of the dynamic model reveal the abundant dynamic behaviour of the coupling system when the axle rotating speed changes, including single period, quasi period, multi-period and chaotic motion, as well as the evolution law from multi-period motion to chaotic motion. And especially, the bearing–axle coupling system is in stable state with a single period motion when the axle rotating speed changes from 410 rpm to 510 rpm, in which the running speed of railway freight wagon is changed from 62 km/h to 80 km/h, the vibration displacement of the coupling system in X direction is between 1.2 mm and 1.8 mm, and the vibration displacement of the coupling system in Y direction is between 1.0 mm and 1.45 mm. Meanwhile, the influence law of axle rotating speed on the stability is obtained by comparing the bifurcation diagram and Floquet multiplier graph of the coupling system.Originality/valueThe numerical simulation data obtained in this study can provide a theoretical evidence for designing the running speed of railway freight wagon, utilizing or controlling the non-linear dynamic behaviours of the proposed coupling system, and ensuring the stability of railway freight wagons.
Why do firms adopt collective incentives? An analysis of family and non-family firms
Authors: Salimi Meysam , Della Torre Edoardo , Miniaci Raffaele 
Published: February 2023

PurposeBy combining structural contingency theory and socio-emotional wealth (SEW) theory, this study aims to identify the organizational determinants of collective performance-related pay (PRP) adoption by examining the interplay between a firm's ownership characteristics (i.e. family or non-family ownership) and other organizational characteristics.Design/methodology/approachThis study adopts a quantitative approach, conducting empirical analyses of a longitudinal dataset of 4,222 Italian companies in the manufacturing sector for 2009–2017. The probability of adopting collective PRP schemes is estimated using the average marginal effects of the probit and linear probability models (LPMs).FindingsThe results show that family firms are less likely to adopt collective PRP schemes than non-family firms. Moreover, ceteris paribus, firm characteristics such as size, age and past (firm and labor) productivity are important determinants of firms' adoption of collective incentive pay; however, the significance and magnitude of their effects vary depending on a firm's ownership structure.Originality/valueThis analysis has two major elements of novelty. First, it increases the knowledge of how organizational contingencies differ in family versus non-family contexts regarding pay decisions. Second, it brings new theoretical perspectives to the pay debate by combining structural contingency theory and SEW theory, thus developing new and fertile theoretical grounds for advancing our understanding of the pay determinants. To the best of authors' knowledge, this is one of the first (if any) studies to shed light on collective PRP in family and non-family firms.
Investigation of the multi-layers of imprinting on corporate working capital management
Authors: Davaadorj Zagdbazar , Enkhtaivan Bolortuya , Weathers Jamie 
Published: February 2023

PurposeThe paper aims to investigate the imprinting effect on working capital (WC) management as higher-level managers' transition to chief executive officer (CEO) positions. This paper proposes that WC management defined as a shorter cash conversion cycle (CCC) can be carried forward to the new firm when the managers are appointed as a CEO.Design/methodology/approachThe authors employ a multivariate regression approach. The data in this study come from two sources: Execucomp which provides data for corporate managers of the largest 2,000 USA firms including S&P 1,500 US and Compustat which provides financial information of firms.FindingsThe authors find a positive imprinting effect of “new” CEOs on WC outcomes – proxied by the CCC. CCC shortens by approximately 16 days when CEOs are efficient managers at previous institutions, predominantly derived from improvements in inventory and payables. The effect is sensitive to individuals' age, familiarity with the industry and high-pressure circumstances.Practical implicationsThe paper includes important implications of WC management for firms to consider, especially during economic crises when liquidity management is a priority.Originality/valueThis paper extends the literature on the imprinting effect on managerial decision-making. The paper offers evidence of cooperative yet dynamic efforts in managing WC during CEO turnover events, which are unique findings.

Authors: Creek Steven A. , Maurer Joshua D. , Kent Justin K. 
Published: February 2023

PurposeThe purpose of this study is to examine how crowdfunding backer perceptions of market orientation and foreignness impact crowdfunding performance in emerging economies.Design/methodology/approachUsing content analysis software, the authors analyzed 756 Kickstarter campaign narratives from the emerging economies of Brazil, Russia, India, China, and South Africa for the period between 2009 and 2019.FindingsThe authors’ results show that behavioral market orientation signals are positively related to amounts raised while decision criteria signals are negatively related. The authors also find that foreign entrepreneur status interacts with the two market orientations to impact funding amounts.Practical implicationsWhen creating crowdfunding campaigns in emerging economies, domestic entrepreneurs should use high levels of behavioral market orientation rhetoric but low levels of decision criteria rhetoric within their campaign narratives.Originality/valueThis study unpacks the components of market orientation and examines their positive and negative effects on crowdfunding success in the context of emerging economies.

Published: February 2023

AbstractBackgroundThe study aimed to fully understand small bowel necrosis, a rare but fatal complication after esophagectomy.MethodsPatients who underwent esophagectomy for esophageal cancer at the Fudan University Shanghai Cancer Center from January 2013 to December 2021 were retrospectively reviewed. Clinical information on the demographics, presenting features, and outcomes of the cases were collected.ResultsOf the 6607 patients during the study period, 11 (0.2%) underwent reoperation due to bowel necrosis, including nine males (81.8%) and two females (18.2%). Among them, eight cases (72.7%) had hypertension and seven (63.6%) suffered from lower thoracic esophageal cancer. Eight (72.7%) and three (27.3%) patients underwent the Ivor‐Lewis and McKewon procedures, respectively. Jejunostomy was performed in nine patients (81.8%). The first signs of bowel necrosis appeared within 5 days after esophagectomy. Abdominal distension and deteriorating renal function were observed in seven patients (63.6%). There was no evidence of mesenteric vascular occlusion in any of the 11 cases, except for the hepatic portal venous gas found in seven patients on the computed tomography (CT) scan. Eight (72.7%) of the 11 patients underwent reoperation within 24 h due to the onset of the first symptoms. Eight (72.7%) had ileal necrosis, and three (27.3%) died.ConclusionClose attention should be paid to patients with abdominal distension, renal function damage, and portal hepatic venous gas after esophagectomy. These patients may suffer from small bowel necrosis, which may result in rapid disease progression. Exploratory laparotomy and bowel resection are effective treatments for such patients.

Published: February 2023

AbstractObjectivesThis study evaluated the impact of a 5‐week educational and supportive program for people newly diagnosed with dementia and their caregivers.MethodsThe study involved a pretest–posttest survey followed by interviews. Wilcoxon signed‐rank test was conducted to determine postprogram changes. Kruskal–Wallis tests measured variation in responses between the people with dementia and their caregivers. Interviews were analysed using the NVivo software identifying themes against the program objectives of improving knowledge on dementia, coping strategies, communication and support services for people with dementia and their caregivers.ResultsFifty‐three dyads (n = 106) completed the survey. There were significant improvements in participants' level of understanding of dementia (z = −8.04, p < 0.001), knowledge of local services (z = −8.11, p < 0.001) and coping with life with dementia (z = −6.93, p < 0.001). These findings were consistent with interview data from 16 dyads.ConclusionsThe increasing number of people with dementia and their caregivers living in the community present health challenges. Programs that assist this group to function well in the community are important. Evaluation of this program indicated improved outcomes in relation to adjusting to life with dementia, enhancing knowledge, fostering communication and reducing feelings of isolation. Areas of improvement included lengthening the program with ongoing contact sessions with program facilitators and other participants. Given the positive effects of the program on this vulnerable group of people, it maybe useful for health‐care agencies involved in dementia care to conduct this type of program as a matter of routine treatment and care for people newly diagnosed with dementia.
The Pedagogical Account of Parliamentarism at India's Founding
Authors: Bhatia Udit 
Published: February 2023

AbstractThis article explores a distinctive approach to parliamentarism advanced by key figures from India's founding period in response to their anxieties about concerns about the masses’ backwardness alongside a commitment to democratic self‐rule. Both orientations, one democratic and the other, suspicious of the peoples’ political capacities, existed alongside each other in tension, generating a dilemma: how could the seemingly backward masses facilitate the overthrow of their backwardness in a democratic process? The thinkers studied in this article responded, I argue, with a pedagogical conception of parliamentarism, which viewed parliament and legislators as bearing the function of preparing the masses for democratic citizenship. Their approach represented a critical departure from the ideal of a deliberative legislative assembly at the apex of the lawmaking process, while avoiding strategies of exclusion historically associated with parliamentarism.
Inclusive urban entrepreneurial ecosystem: An exploration of factors affecting organizational ambidexterity
Authors: Shakiba Hojjat , Pazhouhan Ayoub , Amiri Saba , Sakhdari Kamal 
Published: February 2023

AbstractOne of the main challenges inclusive urban entrepreneurial ecosystems (IUEEs) face is balancing their organizations' two opposing individual and cooperative activities. The closest concept in the management of dual structures is the so‐called organizational ambidexterity (OA). We refer to it as “Individual–Collective Organizational Ambidexterity”. Thus, it is necessary to explore factors affecting the OA of the IUEE's organizations to benefit simultaneously from individual and collective potentials and form successfully. To do so, a model was designed by examining the factors affecting the OA capacity of the IUEE's organizations. The statistical population was organizations involved in the IUEE of 36 cities in Kermanshah province, one of the poorest provinces in IRAN (N = 2041). 328 valid responses were collected as statistical sample based on the sampling table of Krejcie and Morgan (from 1970), and through the proportional stratified sampling method. The main instrument was a questionnaire. Data were analyzed by SPSS version 26 and Smartpls3 software. The results showed among the factors studied, diversity, learning orientation, and promotion of entrepreneurial culture had a positive and significant effect on OA. Networking capacities and commitment to collaboration in the ecosystem did not significantly affect OA. OA also had a positive and significant effect on the performance of IUEE. The discussion eventually suggests the future directions of the research. The findings of this study can be used to develop IUEEs and achieve entrepreneurial cities.
