Wang J, Zuo L, Cordente Martínez C. Basketball technique action recognition using 3D convolutional neural networks. Sci Rep 2024; 14:13156. [PMID: 38849454 PMCID: PMC11161614 DOI: 10.1038/s41598-024-63621-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 05/30/2024] [Indexed: 06/09/2024] Open
Abstract
This research investigates the recognition of basketball techniques actions through the implementation of three-dimensional (3D) Convolutional Neural Networks (CNNs), aiming to enhance the accurate and automated identification of various actions in basketball games. Initially, basketball action sequences are extracted from publicly available basketball action datasets, followed by data preprocessing, including image sampling, data augmentation, and label processing. Subsequently, a novel action recognition model is proposed, combining 3D convolutions and Long Short-Term Memory (LSTM) networks to model temporal features and capture the spatiotemporal relationships and temporal information of actions. This facilitates the facilitating automatic learning of the spatiotemporal features associated with basketball actions. The model's performance and robustness are further improved through the adoption of optimization algorithms, such as adaptive learning rate adjustment and regularization. The efficacy of the proposed method is verified through experiments conducted on three publicly available basketball action datasets: NTURGB + D, Basketball-Action-Dataset, and B3D Dataset. The results indicate that this approach achieves outstanding performance in basketball technique action recognition tasks across different datasets compared to two common traditional methods. Specifically, when compared to the frame difference-based method, this model exhibits a significant accuracy improvement of 15.1%. When compared to the optical flow-based method, this model demonstrates a substantial accuracy improvement of 12.4%. Moreover, this method showcases strong robustness, accurately recognizing actions under diverse lighting conditions and scenes, achieving an average accuracy of 93.1%. The research demonstrates that the method reported here effectively captures the spatiotemporal relationships of basketball actions, thereby providing reliable technical assessment tools for basketball coaches and players.

Abstract
INTRODUCTION AND IMPORTANCE Obesity is a global epidemic, and bariatric surgery is an effective treatment. During this surgery, rare abnormalities in the small intestine, like ectopic pancreas (EP), can be found. CASE PRESENTATION A 16-year-old male presented at the surgical clinic with a complaint of morbid obesity, weighing 140 KG. Since he was unable to commit to a diet, bariatric surgery was performed. During the surgery, the gastrointestinal tract was examined, and an incidental finding was noted in the wall of the proximal jejunum. The histopathology report revealed that the excisional biopsy was a complete EP in the proximal jejunum. The patient was discharged from the hospital on the first postoperative day, and his condition remained stable. CLINICAL DISCUSSION Our case of EP stood out due to its larger size, measuring 3.5 cm in diameter, while EP lesions are typically smaller, despite its size, the patient did not experience any symptoms. EP is more commonly found in individuals between 40 and 50 years old, with a higher incidence in males. However, our patient is only 16 years old. CONCLUSION Surgical resection is the most effective treatment, preventing malignant transformation and future complications. To the best of our knowledge, this is the first documented case of incidentally detected heterotopic pancreatic tissue in jejunum during a bariatric procedure in Syria, and it is also the fourth case in the medical literature.

Abstract
OBJECTIVE To identify CT features and establish a nomogram, compared with a machine learning-based model for distinguishing gastrointestinal heterotopic pancreas (HP) from gastrointestinal stromal tumor (GIST). MATERIALS AND METHODS This retrospective study included 148 patients with pathologically confirmed HP (n = 48) and GIST (n = 100) in the stomach or small intestine that were less than 3 cm in size. Clinical information and CT characteristics were collected. A nomogram on account of lasso regression and multivariate logistic regression, and a RandomForest (RF) model based on significant variables in univariate analyses were established. Receiver operating characteristic (ROC) curve, mean area under the curve (AUC), calibration curve and decision curve analysis (DCA) were carried out to evaluate and compare the diagnostic ability of models. RESULTS The nomogram identified five CT features as independent predictors of HP diagnosis: age, location, LD/SD ratio, duct-like structure, and HU lesion/pancreas A. Five features were included in RF model and ranked according to their relevance to the differential diagnosis: LD/SD ratio, HU lesion/pancreas A, location, peritumoral hypodensity line and age. The nomogram and RF model yielded AUC of 0.951 (95% CI: 0.842-0.993) and 0.894 (95% CI: 0.766-0.966), respectively. The DeLong test found no statistically significant difference in diagnostic performance (p > 0.05), but DCA revealed that the nomogram surpassed the RF model in clinical usefulness. CONCLUSION Two diagnostic prediction models based on a nomogram as well as RF method were reliable and easy-to-use for distinguishing between HP and GIST, which might also assist treatment planning.

Abstract
INTRODUCTION AND IMPORTANCE Heterotopic Pancreas (HP) is defined by the presence of pancreatic tissue in an anatomically distinct location from the main pancreas. While often clinically silent, it may present symptomatically. If located in the gastric antrum, HP may cause gastric outlet obstruction (GOO). The objective of this paper is to present a rare case of HP in the gastric antrum causing GOO. CASE PRESENTATION Herein, we report a 43-year-old man who presented with abdominal pain and non-bilious emesis in the setting of COVID-19 infection and alcohol consumption. During the initial workup, computed-tomography (CT) was non-specific but demonstrated GOO, concerning for cancer. Cold forceps biopsies taken during esophagogastroduodenoscopy (EGD) confirmed benign HP. Since the patient was symptomatic from gastric outlet compression, he underwent resection via laparoscopic distal gastrectomy and Billroth II gastrojejunostomy. At 1-month postoperative follow-up, the patient recovered uneventfully. We hypothesized that GOO by HP in this case may have been associated with cumulative effects of alcohol consumption and COVID-19 infection on the ectopic tissue. CLINICAL DISCUSSION HP is rare and difficult to diagnose preoperatively. When located in gastric antrum, HP can cause GOO, mimicking gastric malignancy. Combination of EGD/EUS, biopsy/FNA, and surgical resection are necessary to definitively make the diagnosis. Finally, it is important to consider that heterotopic pancreatitis or structural changes in HP may occur due to classic pancreatic stressors like alcohol and viral infections. CONCLUSION HP may cause GOO presenting with non-bilious emesis and abdominal pain, mistaken for malignancy on CT imaging.

Abstract
RATIONALE Heterotopic pancreas is a pancreatic tissue that occurs outside the normal anatomical site, the most common site is antrum. Due to the lack of specific imaging and endoscopic signs, heterotopic pancreas especially those occurring in the rare site, are often misdiagnosed, and leading to unnecessary surgical treatment. Endoscopic incisional biopsy and endoscopic ultrasound-guided fine-needle aspiration are effective means for diagnosing heterotopic pancreas. We reports a case of extensive heterotopic pancreas in a rare site, which was finally diagnosed by this way. PATIENT CONCERNS A 62-year-old man was admitted due to the presence of an angular notch lesion, which was suspected as gastric cancer before. He denied any history of tumor or gastric disease. DIAGNOSES No abnormality was found in the physical examination and laboratory testing after admission. Computed tomography showed localized thickening of the gastric wall measuring 30 mm in the long diameter. Gastroscope revealed a nodular-like submucosal protuberance at the angular notch with size of about 3*4 cm. Ultrasonic gastroscope showed that the lesion was located in the submucosa. The lesion exhibited mixed echogenicity. The diagnosis can not be identified. INTERVENTIONS 2 times of incision biopsy were performed to make a clear diagnosis. Finally, appropriate tissue specimens were obtained for pathology testing. OUTCOMES The patient was diagnosed as heterotopic pancreas according to pathology. He was recommended to undergo observation and regular follow-ups rather than surgery. Then he was discharged home with no discomfort. LESSONS Heterotopic pancreas occurring in the angular notch is extremely rare, the site is scarcely reported in the relevant literature. Therefore, it is easy to be misdiagnosed. In the cases of an vague diagnosis, endoscopic incisional biopsy or endoscopic ultrasound-guided fine-needle aspiration may be a good choice.

Abstract
The ectopic pancreas is a benign subepithelial tumor (SET) mostly found incidentally in the stomach and duodenum. Here, we present computed tomography (CT) scans and endoscopic ultrasound (EUS) images from a 71-year-old Taiwanese man newly diagnosed with colonic adenocarcinoma. CT examination revealed a mural nodule in the proximal jejunum, with good enhancement after IV contrast medium administration. Push enteroscopy was performed to localize the lesion and evaluate its nature, and a 1 cm subepithelial lesion was found. The lesion appeared hyperechoic within the submucosal layer of the bowel wall on endoscopic ultrasound examination. A tattoo was performed, and the lesion was removed during the resection of colon cancer. The histopathology confirmed the presence of pancreatic tissue inside. As far as we know, this is the first description in the literature of an endoscopic ultrasound finding of a jejunal ectopic pancreas.

Abstract
Heterotopic pancreas (HP) is defined as pancreatic tissue lacking vascular or anatomic connection with the normal pancreas. Surgical resection is often indicated for symptomatic gastric HP. However, intraoperative identification of gastric HP is often difficult during laparoscopic surgery. Herein, we describe a patient with gastric HP, which was marked with SPOT® dye (GI Supply, Camp Hill, PA, USA). The dye was seen clearly laparoscopically facilitating total excision of the lesion. The final pathology report confirmed the presence of heterotopic pancreatic tissue including pancreatic acini, small pancreatic ducts tissue with islets of Langerhans in the deep gastric submucosal area. There were no postoperative complications, and the patient was symptom-free. To the best of our knowledge, this was the first case report in the literature in which endoscopic tattooing of gastric HP before laparoscopic resection was performed. This method of localization was simple and reliable in children.

Abstract
Heterotopic pancreas is defined as the presence of ectopic pancreatic tissue outside boundaries of the pancreas without vascular and duct system connection with the pancreas. Ectopic locations are mostly found anywhere in the gastrointestinal tract such as the stomach (24-38%), the duodenum (9-36%), and the jejunum (0.5-27%). Clinical manifestations are not specific, vague, and misdiagnosed another digestive disease. Most cases are incidentally detected by histological examination of specimens resected for different pathologies during endoscopy, surgery, or even autopsy. We report a case of a 31-year-old man who admitted to the hospital with the reason of epigastric pain for 3 days. Clinical examination showed mild epigastric tenderness. The past medical history of patient was unremarkable. A submucosal lesion was observed in the first part of the duodenum during endoscopy. Computed tomography and endoscopic ultrasonography findings were suspected to be heterotopic pancreatic tissue. After laparoscopic surgery for biopsy, it was histologically confirmed duodenal ectopic pancreas. It is difficult to differentiate gastrointestinal pancreatic heterotopia from gastrointestinal stromal tumors, leiomyoma, or lymphomas by using endoscopy because ectopic tissue is mostly located in the submucosal layer. In addition, rare cases of ectopic pancreatic tissue transform malignancy. Surgical treatment should be considered to take adequate tissue samples for biopsy or resect the lesions in symptomatic patients. Duodenal pancreatic heterotopia is an uncommon congenital malformation and most patients are asymptomatic. Histological examination is essential to exclude malignant lesions and to have an appropriate treatment.
