Achieving useful data analytics for marketing: Discrepancies in information quality for producers and users of information
Authors: Morales-Serazzi Manuel , González-Benito Óscar , Martos-Partal Mercedes 
Published: March 2021

This study proposes as a key cause of the high failure rates in the implementation of analytical projects for marketing decisions, the discrepancy in the information quality (DIQ) perceived between producers (information technology [IT]) and users (marketing) of knowledge. Given that the DIQ between agents is a determining factor in the success of the ability to data analytics, this study focuses on examining this concept and its causes, specifically the resources related to data analytics that influence DIQ. The results of the surveys carried out with the IT and marketing managers of 95 companies in Spain, analyzed with a comparative methodological approach (dyadic), reveal the sources of the discrepancy, namely, the quality of the data, the technological capabilities, the talent, Chief Executive Officer (CEO) support, and alignment of the data plan with the marketing plan.

Mismanaged Ankle Fractures, is it too Late to Save the Joint?
Authors: Abd-Ella Mohamed M. 
Published: March 2021

Category: Trauma; Ankle Introduction/Purpose: Mimanaged ankle fractures with a short fibula, talat shift, syndesmotic widening, malunion or nonunion following inappropriate conservative treatment or inadequate operative treatment are very challenging, especially in young patients. Whether or not to revise the fracture fixation after a period of time with weight bearing with a malaligned joint is a difficult question regarding the value of the operation after that time to prevent arthritis.The aim of the study was to evaluate the effect of operative intervention in these cases in improving symptoms and preventing arthritis Methods: The study was a prospective study. Inclusion criteria were mismanaged ankle fractures with a reasonable range of motion. Exclusion criteria were infection, severe arthritis, complete loss of motion, ischemia and diabetes. Standing radiographs for both limbs and CT scans were obtained for all patients to analyze the problem. Operative treatment was planned accordingly, and regular follow up was performed clinically and radiologically. Results: 29 patients were included. The average duration from the primary injury or primary fixation was 6 months (range 1.5 to 28 months). The lateral malleolus with or without the syndesmosis were affected in 25 out of 29 cases, the posterior malleolus was affected in 2 cases, the medical malleolus in 6 cases and the deltoid ligament in 12 cases. The minimum follow up duration was 9 months with a range from 9 months to 6 years. Three patients required an ankle fusion later. Ten patients report excellent results, 10 patients report good results, 4 patients report fair results and five patients report bad results, three of them underwent ankle arthrodesis.AOFAS score improved significantly from a mean of 28 points preoperative to a mean 85 points postoperative. Conclusion: Perfect primary treatment for ankle fractures is the best method for a good prognosis, but it is not late to reconstruct the joint if there is a reasonable range of motion.This can give good results and delay fusion, and it can make arthroplasty a valid option by restoring ankle anatomy and stability.

Authors: Gaston Tara E. , Skibicki Hope , Chapter Megan C. , Cheesman Quincy , Daniel Joseph N. 
Published: March 2021

Category: Sports; Ankle Introduction/Purpose: Operative treatment of chronic Achilles insertional tendinosis (AIT) involves tendon debridement, removal of the retrocalcaneal bursitis, and excision of the calcaneal exostosis, often followed by repair of the Achilles tendon and deep tendon transfer. The literature describes a variety of techniques without a single standard of care. The purpose of this study is to describe a novel approach for the treatment of chronic AIT and report clinical outcomes and complications of this technique. Methods: A retrospective review was performed of 57 patients with chronic AIT who were treated with the proposed surgical technique by a single surgeon from January 2015 through January 2019. Patient demographics, pain scores, functional outcome scores, and complications were reviewed. A telephone survey was also utilized to assess patient satisfaction. Following the breakdown of the data, comparisons of the preoperative scores were compared to the postoperative outcomes using Mann- Whitney U testing. Results: Preoperative VAS pain scores and VR-12 Physical scores were significantly improved at two year follow up. Additionally, patients described the outcome of their surgery as, ‘very good.’ Complications were also few and minimal. Three (5.3%) patients experienced superficial skin breakdown requiring return to the operating room and three (5.3%) developed postoperative cellulitis which responded to local care and oral antibiotics. There were no ruptures or record of recurrence of disease or pain. Conclusion: The technique described in this paper utilizes an excisional debridement of the central portion of the Achilles tendon in the shape of an apex superior triangle and therefore, does not require detachment of the tendon from its insertion on the calcaneus (Image 1). Functional outcome scores and pain significantly improved at two years follow up. Postoperative complications were similar to those previously reported with superficial wound breakdown being the most common. In conclusion, the authors encourage the use of this reliable, reproducible, and effective technique for the treatment of patients with chronic AIT.

Abstract
Introduction: The most kind of dementia is Alzheimer's disease. Alzheimer’s is a type of degenerative cerebrovascular disorder which exacerbates over time. Meanwhile, anticholinergic drugs can potentially modify the risk factors. As different studies have achieved different results and the clinical findings of these interventions have not been conclusive, the objective of this research will be to evaluate the effect of anticholinergic drugs on the risk of dementia.Materials& Methods: This systematic review and meta-analysis with no language limitation between 1988.12.15 and 2020.12.15 will search WoS, EMBASE, MEDLINE/PubMed, Scopus, ProQuest electronic databases and grey literature. Our search strategy with suitability criteria evaluating the effect of anticholinergic drugs on the risk of dementia. Two authors will independently implement the selection phases, data extraction, and quality assessment. Any discrepancies between reviewers will be resolved by consensus; otherwise, the viewpoint of a third specialist person will be applied. The reviewers will evaluate the risk of bias using NOS. We will conduct a meta-analysis with Random Effect Model or Fixed Effect Model according to severity of methodological heterogeneity. The results will be presented via the forest plot for the composition of final studies’ data, to demonstrate the separated and combined frequency and their corresponding 95% CIs and summary tables and narrative summaries. Using I2 statistics and the Q-statistic test, the statistical heterogeneity will be evaluated. For evaluating the possible reporting bias, the Funnel plot will be used; also Begg's and Egger's tests will be applied for significant results of the publication bias, and the Fill & Trim method for reformed publication bias. Ethical and dissemination: The systematic review findings will be published in a peer-reviewed journal and will also be presented at national/international academic and clinical conferences.PROSPRO Registration: CRD42020219612

BackgroundRecruitment processes for clinical trials of digital interventions for psychosis are seldom described in detail in the literature. Although trial staff have expertise in describing barriers to and facilitators of recruitment, a specific focus on understanding recruitment from the point of view of trial staff is rare, and because trial staff are responsible for meeting recruitment targets, a lack of research on their point of view is a key limitation.ObjectiveThe primary aim of this study was to understand recruitment from the point of view of trial staff and discover what they consider important.MethodsWe applied pluralistic ethnographic methods, including analysis of trial documents, observation, and focus groups, and explored the recruitment processes of the EMPOWER (Early Signs Monitoring to Prevent Relapse in Psychosis and Promote Well-being, Engagement, and Recovery) feasibility trial, which is a digital app–based intervention for people diagnosed with schizophrenia.ResultsRecruitment barriers were categorized into 2 main themes: service characteristics (lack of time available for mental health staff to support recruitment, staff turnover, patient turnover [within Australia only], management styles of community mental health teams, and physical environment) and clinician expectations (filtering effects and resistance to research participation). Trial staff negotiated these barriers through strategies such as emotional labor (trial staff managing feelings and expressions to successfully recruit participants) and trying to build relationships with clinical staff working within community mental health teams.ConclusionsResearchers in clinical trials for digital psychosis interventions face numerous recruitment barriers and do their best to work flexibly and to negotiate these barriers and meet recruitment targets. The recruitment process appeared to be enhanced by trial staff supporting each other throughout the recruitment stage of the trial.

LANGUAGE NOTE | Document text in English; abstract also in Chinese.
The purposes of this study were to investigate (1) the contribution of the different muscular strength to the performance of 30-second indoor rowing maximal test (30-sec Test) and 6-minute indoor rowing all-out test (6-min Test); and (2) the effects of 6-week handgrip strength training on the performance of 30-secTest and 6-minTest. Twenty young male rowers (age: 14.7±1.2years, height: 172.4±7.7cm, weight: 66.3±8.9kg) were randomized (n=10) into the experimental and control groups. The experimental group performed 3 sets of 12 Repetition Maximum barbell wrist curl training 3 times per week for 6 weeks. A series of tests for muscular strength and the two rowing performances were carried out Pre and Post the training period. The results of 30-secTest was significant correlated with the sum of left and right handgrip strength (HGS) (r = .76 - .78; p<.01) and the leg and back strength (LBS) (r = .65 -. 66; p<.05). Significant correlation was recorded between the performance of 6-minTest and the LBS (r=.84; p<.01), but not with the HGS. Results of a paired t-test show that only the HGS improved significantly in the experimental group with an overall improvement of 9.6% (p<.05) but produced no significant changes in the performance of 30-sec Test and 6-minTest.

AJANTA'S DRAWINGS AND COLOR COMBINATIONS (IN THE PERSPECTIVE OF GUPTA ART)
Authors: Dubey Shraddha 
Published: March 2021

The Gupta period is called the Golden Age of India's history. In this era of happiness, prosperity and splendor, all arts were equally upgraded. The biggest gift of this era is Ajanta's frescoes. The inaudible works created by painters sitting in deep cenotaphic caves are unmatched. In this, the content and themes were not only taken from the life and Jataka tales of Lord Tathagata, but kept them bound in any limit. In them, hundreds of years of folklore is mirrored like a mirror. In Ajanta, 29 caves have been made by cutting a semi-crescent mountain. It is divided into groups. Among them, the tenth and ninth caves are in the middle group.Most of the pictures of Ajanta caves have been erased, but the remaining ones are amazing. The earliest paintings have the influence of Shung Kala. Lord Tathagata is seated in a view of the ninth cave, King Rani Amatigan and the worshiping monks surround him. Amatyas have turbaned threads at the ends and are wearing heavy jewelery in the hands and neck. With the shapes, they appear to be people of a primitive caste from the south. We can call it the earlier tradition of Ajanta painting. There is more use of gray color in it, but due to the use of natural colors, every object can be seen clearly as above. Due to the lack of bright colors, they reveal the plot seriously and give impetus to its spiritual nature.
गुप्तकाल भारत के इतिहास का स्वर्ण-युग कहा जाता है। सुख समृद्धि और वैभव के इस काल में सभी कलाओं का समान रूप से उन्नयन हुआ। इस युग की सबसे बड़ी देन है अजंता के भित्तिचित्र। चित्रकारों ने गहन अधंकरामयी गुफाओं में बैठकर जिन अपार्थिव कृत्तियों का सृजन किया वे अप्रतिम है। इनमें कथावस्तु और विषय तो भगवान तथागत के जीवन और जातक कथाओं से ही लिए किन्तु उन्हें किसी सीमा में बांध कर नहीं रखा। उनमें सैकड़ों वर्षों का लोकजीव दर्पण की भाँति प्रतिबिम्बित है।अजंता में अर्ध-चन्द्राकार पर्वत को काटकर 29 गुफाएँ बनाई गई है। यह समूहों में बंटी हुई है। इनमें दसवीं और नवीं गुफाएँ बीच के समूह में है।अजंता की गुफाओं के अधिकांष चित्र मिट चुके हैं परन्तु जो शेष है वे अद्भुत हैं। सबसे पुराने चित्रों पर शुंग कला का प्रभाव है। नवीं गुफा के एक दृश्य में जो मिट सा गया है भगवान तथागत बैठे हैं, राजा रानी अमात्यगण और उपासक भिक्षु उन्हें घेरे हुए हैं। अमात्यों के सिरों पर लटूदार पगड़ियाँ है और वे हाथों और गले में भारी-भारी आभूषण पहने हैं। आकृतियों से वे दक्षिण की ही किसी आदिम जाति के लोग लगते हैं। इसे हम अजंता चित्रकला की पूर्व परम्परा कह सकते हैं। इसमें धूसरित रंग का प्रयोग अधिक है किन्तु प्राकृतिक रंगों के प्रयोग की वजह से प्रत्येक वस्तु ऊपर वर्णानुसार स्पष्ट नजर आती है। चटख रंग न होने की वजह से यह कथानक को गंभीरता से प्रकट करते हैं और उसके आध्यात्मिक स्वरूप को गति प्रदान करते हैं।

OBJECTIVE
Carotid webs (CWs) have increasingly been recognized as a cause of recurrent ischemic stroke. However, the natural history and clinical course of CWs remain unclear. The authors aimed to clarify the prevalence, imaging features, and optimal treatment of CWs in a Japanese cohort study.

METHODS
A series of 444 consecutive Japanese patients who had undergone CTA of the head and neck between April 2011 and October 2016 was retrospectively reviewed. CW was diagnosed on CT angiograms as a membrane-like intraluminal filling defect along the posterior wall of the carotid bulb or the origin of the internal carotid artery (ICA) on oblique sagittal images and a corresponding thin septum on axial images.

RESULTS
Two patients with CWs were identified among 132 patients with suspected stroke. The prevalence of CWs among symptomatic patients with suspected stroke was 1.5%. The prevalence of asymptomatic CWs was 2.2% (7 of 312 cases). The CWs were located in the posterior wall of the carotid bulb in 7 patients and just distal to the ICA origin in 2 patients. There were no apparent differences in the location or lesion length between symptomatic and asymptomatic CWs. Four of the 7 asymptomatic CWs remained asymptomatic for at least 2 years of follow-up. Two patients with symptomatic CWs developed recurrent cerebral infarction and transient ischemic attack despite being on a regimen of oral antiplatelet agents, and carotid endarterectomy was performed as radical treatment. Patients with CWs were younger than controls (median age 55 vs 69 years, p = 0.003) and were less frequently male than controls (33% vs 72%, p = 0.025). CW cases showed significantly fewer common atherosclerosis risk factors than the control group (p < 0.05).

CONCLUSIONS
Although limited to CTA patients, this study reported on the prevalence and common site of CWs, focusing on symptomatic and asymptomatic Japanese patients. Extensive cross-sectional and prospective observational studies are warranted to elucidate the overall prevalence and natural history of CWs.
Correction of the skull density ratio for transcranial MRI-guided focused ultrasound thalamotomy: clinical significance of predicting therapeutic temperature
Authors: Hori Hiroki , Iwamuro Hirokazu , Nakano Masayuki , Ouchi Takahiro , Kawahara Takashi , Taira Takaomi , Abe Keiichi , Iijima Ken , Yamaguchi Toshio 
Published: March 2021

OBJECTIVE
In transcranial magnetic resonance imaging–guided focused ultrasound (TcMRgFUS), a high skull density ratio (SDR) is advantageous to achieve a sufficiently high temperature at the target. However, it is not easy to estimate the temperature rise because the SDR shows different values depending on the reconstruction filter used. The resolution characteristic of a computed tomography (CT) image depends on a modulation transfer function (MTF) defined by the reconstruction filter. Differences in MTF induce unstable SDRs. The purpose of this study was both to standardize SDR by developing a method to correct the MTF and to enable effective patient screening prior to TcMRgFUS treatment and more accurate predictions of focal temperature.

METHODS
CT images of a skull phantom and five subjects were obtained using eight different reconstruction filters. A frequency filter (FF) was calculated using the MTF of each reconstruction filter, and the validity of SDR standardization was evaluated by comparing the variation in SDR before and after FF correction. Subsequently, FF processing was similarly performed using the CT images of 18 patients who had undergone TcMRgFUS, and statistical analyses were performed comparing the relationship between the SDRs before and after correction and the maximum temperature in the target during TcMRgFUS treatment.

RESULTS
The FF was calculated for each reconstruction filter based on one manufacturer's BONE filter. In the CT images of the skull phantom, the SDR before FF correction with five of the other seven reconstruction filters was significantly smaller than that with the BONE filter (p < 0.01). After FF correction, however, a significant difference was recognized under only one condition. In the CT images of the five subjects, variation of the SDR due to imaging conditions was significantly improved after the FF correction. In 18 cases treated with TcMRgFUS, there was no correlation between SDR before FF correction and maximum temperature (rs = 0.31, p > 0.05); however, a strong positive correlation was observed after FF correction (rs = 0.71, p < 0.01).

CONCLUSIONS
After FF correction, the difference in SDR due to the reconstruction filter used is smaller, and the correlation with temperature is stronger. Therefore, the SDR can be standardized by applying the FF, and the maximum temperature during treatment may be predicted more accurately.
Management strategies for recurrent pediatric craniopharyngioma: new recommendations
Authors: Fouda Mohammed A. , Karsten Madeline , Staffa Steven J. , Scott R. Michael , Marcus Karen J. , Baird Lissa C. 
Published: March 2021

OBJECTIVE
The goal of this study was to identify the independent risk factors for recurrence or progression of pediatric craniopharyngioma and to establish predictors of the appropriate timing of intervention and best management strategy in the setting of recurrence/progression, with the aim of optimizing tumor control.

METHODS
This is a retrospective cohort study of all pediatric patients with craniopharyngioma who were diagnosed and treated at Boston Children’s Hospital between 1990 and 2017. This study was approved by the institutional review board at Boston Children’s Hospital. All statistical analyses were performed using Stata software.

RESULTS
Eighty patients (43 males and 37 females) fulfilled the inclusion criteria. The mean age at the time of diagnosis was 8.6 ± 4.4 years (range 1.2–19.7 years). The mean follow-up was 10.9 ± 6.5 years (range 1.3–24.6 years). Overall, 30/80 (37.5%) patients developed recurrence/progression. The median latency to recurrence/progression was 12.75 months (range 3–108 months). Subtotal resection with no adjuvant radiotherapy (p < 0.001) and fine calcifications (p = 0.008) are independent risk factors for recurrence/progression. An increase (%) in the maximum dimension of the tumor at the time of recurrence/progression was considered a statistically significant predictor of the appropriate timing of intervention.

CONCLUSIONS
Based on the identified independent risk factors for tumor recurrence/progression and the predictors of appropriate timing of intervention in the setting of recurrence/progression, the authors propose an algorithm for optimal management of recurrent pediatric craniopharyngioma to increase the likelihood of tumor control.
