A Case Report of Hide-Line-Suture-Prosthesis Repair for Anal Fistula

Hide-line-suture-prosthesis repair was introduced by Yibing Li from Shenzhen TCM Anorectal Hospital. In his early years, it was used in rectovaginal fistula, in which it achieved good curative effect. As the pathology of rectovaginal fistula and anal fistula is similar, Yibing Li innovated and applied it to anal fistula cases. This is a case report of a patient with low complex anal fistula who was treated in Shenzhen TCM Anorectal Hospital after two surgeries. The purpose of this report is to share the diagnosis and treatment experience in this case, so as to provide reference for clinicians.

Full depth CNN classifier for handwritten and license plate characters recognition

Character recognition is an important research field of interest for many applications. In recent years, deep learning has made breakthroughs in image classification, especially for character recognition. However, convolutional neural networks (CNN) still deliver state-of-the-art results in this area. Motivated by the success of CNNs, this paper proposes a simple novel full depth stacked CNN architecture for Latin and Arabic handwritten alphanumeric characters that is also utilized for license plate (LP) characters recognition. The proposed architecture is constructed by four convolutional layers, two max-pooling layers, and one fully connected layer. This architecture is low-complex, fast, reliable and achieves very promising classification accuracy that may move the field forward in terms of low complexity, high accuracy and full feature extraction. The proposed approach is tested on four benchmarks for handwritten character datasets, Fashion-MNIST dataset, public LP character datasets and a newly introduced real LP isolated character dataset. The proposed approach tests report an error of only 0.28% for MNIST, 0.34% for MAHDB, 1.45% for AHCD, 3.81% for AIA9K, 5.00% for Fashion-MNIST, 0.26% for Saudi license plate character and 0.97% for Latin license plate characters datasets. The license plate characters include license plates from Turkey (TR), Europe (EU), USA, United Arab Emirates (UAE) and Kingdom of Saudi Arabia (KSA).

How consumption-supportive packaging functionality influences consumers’ purchase intentions: the mediating role of perceived product meaningfulness

Purpose The purpose of this paper is to provide the first empirical evidence on how consumption-supportive packaging functionality influences consumers’ purchase intentions. Consumption-supportive packaging functionality implies that the packaging itself serves a function that actively helps users achieve their consumption goals and that supports the objectives consumers have in mind when using it. Design/methodology/approach To achieve the research goal, this study presents four between-participant experimental studies. In the studies, this paper tests for the direct effect of consumption-supportive packaging functionality on consumers’ purchase intentions across different product categories. Moreover, this study tests for the mediating effect of perceived product meaningfulness to explain the underlying mechanism (Studies 2 and 3) and for the moderating effect of product complexity (Study 4). Findings This paper shows that consumption-supportive packaging functionality leads to higher purchase intentions. The findings also reveal that perceived product meaningfulness is one underlying mechanism that helps us to explain the positive effect of consumption-supportive packaging functionality on purchase intention. Moreover, findings reveal that the positive effect of consumption-supportive packaging functionality only works for low-complex products, but not for high-complex ones. Research limitations/implications This research offers a new perspective on package design, and thus advances the understanding of how to package functionality can influence consumer responses. Moreover, this study contributes to the Gestalt theory because it applies a holistic design view on the packaging that influences product perception. Practical implications For low complex products, marketing managers should consider integrating packaging functionality into their communication strategy to focus on the overall Gestalt of the product. Product designers should integrate consumption-supportive packaging functionality in the product design to evoke positive consumer responses. Originality/value The research gives first empirical evidence on how and when consumption-supportive packaging functionality influences consumers’ product evaluations.

Effective operating room (OR) utilization by performing low-complex surgical procedures during the 2020 corona pandemic

Purpose The SARS-CoV-2 pandemic has almost stopped all elective surgical treatment throughout the world. As operating room (OR) capacities are reduced everywhere to ensure availability of intensive care capacities, especially low-complex surgical procedures are often postponed. These include totally implantable central-venous access ports which are important for the oncologic treatment of cancer patients. Methods In our study, we investigated the potential of an outpatient surgical centre (OSC) in terms of workflow effectiveness compared to the central operating room complex (COR) of a university hospital using low-complex surgical procedures as an example. Data of 524 consecutive patients who received a Port-a-cath procedure (422 implantations (80.5%) and 102 explantations (19.5%)) in our department between February 2019 and February 2020 were evaluated. Results A total of 277 patients were operated in outpatient surgical centre (OSC), and 247 patients received the procedure in the central OR (COR) complex. Grade II and III complications according to the Clavien–Dindo classification occurred in 5.2% (OSC) and 7.3% (COR) of patients. Incision-to-suture time was significantly quicker in the OSC group (36 vs. 42 min., p < 0.032). Total OR time (01:08 vs. 01:20 h) and preparation-to-incision time were also shorter in the OSC group (12 vs. 17 min., p < 0.002). Conclusion In order to ensure effective OR utilization especially in times of the corona pandemic, the use of smaller decentralized OR units, e.g., outpatient surgical centres, for performing low-complex surgical cases is beneficial. Our study revealed shorter total OR and preparation-to-incision times.
