“…Venous thrombosis and ischemic stroke in patients with active cancer had been reported due to cancer related hypercoagulability [2,5], and perioperative venous thrombosis and ischemic stroke had also been reported in cancer patients due to surgery related hypercoagulability [9,10]. In this case, both cancerrelated hypercoagulability and surgery-related hypercoagulability may together promote the occurrence of fatal ischemic stroke following by pulmonary embolism within 24 hours after surgery.…”

“…Not only that, more and more studies found that DVT and ischemic stroke may occur at the same time, and together threaten life for the patient with cancer. In addition, since surgery was still one of the main therapies for cancers and anticoagulant therapy was discontinued during perioperative period, perioperative DVT and ischemic stroke, which are common complications of patients with surgical therapy and are involved surgery-related hypercoagulability [7,8], also independently or jointly lead to poor prognosis of patients with cancer [9,10].…”

Background: Deep venous thrombosis (DVT) including limber and pulmonary embolism is a common complication of cancer. DVT and ischemic stroke may independently or jointly lead to poor prognosis in cancer patients. Case presentation: A 36-year-old female patient, received insertion of inferior vena cava filter and oral rivaroxaban for deep venous thrombosis in limbers and pulmonary artery, was suspected of cervical cancer for a three-month history of vaginal discharge and was transferred to our hospital for further treatment. After cervical tissue biopsy and pelvic cavity magnetic resonance imaging (MRI) examination, she was diagnosed with cervical adenocarcinoma (stage Ⅱ A). She discontinued taking oral rivaroxaban two days before surgery. Within 24 hours after ovariohysterectomy, she suffered from ischemic stroke following by pulmonary embolism，and was transferred to the intensive care unit（ICU）and received therapies including mechanical ventilation, mannitol and nadroparin calcium. Nevertheless, she worsened for cerebral hernia. Eventually, her family refused further treatment for her. Conclusions: It was still a challenge for clinicians to prevent arterial and venous thrombosis in cancer patients, especially in perioperative period with elevated risk for ischemic vascular events.

“…Perioperative stroke is a cerebrovascular incident that can arise intra-operatively. A study by Sukegawa et al [ 159 ] described the case of a female patient who experienced peri-operative stroke. The authors demonstrated that there was no prophylaxis for the incidence of perioperative stroke in patients undergoing surgery for oral, neck, and head cancer.…”

One of the primary causes of disability and mortality in the adult population worldwide is stroke. A person’s general health is significantly impacted by their oral and dental health. People who have poor oral health are more susceptible to conditions such as stroke. Stroke risk has long been linked to oral and dental conditions. The risk of stroke and its cost impact on the healthcare systems appear to be significantly reduced as a result of the decline in the incidence and prevalence of oral and dental illnesses. Hypothetically, better management of oral hygiene and dental health lead to reduced stroke risk. To the authors’ best knowledge, for the first time, the potential link between dental health and stroke were cross-examined. The most typical stroke symptoms, oral and dental illnesses linked to stroke, and the role of oral healthcare professionals in stroke prevention are revealed. The potential mediating processes and subsequent long-term cognitive and functional neurological outcomes are based on the available literature. It must be noted that periodontal diseases and tooth loss are two common oral health measures. Lack of knowledge on the effects of poor oral health on systemic health together with limited access to primary medical or dental care are considered to be partially responsible for the elevated risk of stroke. Concrete evidence confirming the associations between oral inflammatory conditions and stroke in large cohort prospective studies, stratifying association between oral disease severity and stroke risk and disease effects on stroke survival will be desirable. In terms of clinical pathology, a predictive model of stroke as a function of oral health status, and biomarkers of systemic inflammation could be useful for both cardiologists and dentists.

“…Most of the histological types of oral cancer are squamous cell carcinomas. Treating oral cancer when it has already advanced in stage has been reported to have a significant impact on the patient's post-treatment quality of life and is associated with a reduced possibility of complete recovery 2 – 4 , which make early detection and treatment of paramount importance.…”

The use of sharpness aware minimization (SAM) as an optimizer that achieves high performance for convolutional neural networks (CNNs) is attracting attention in various fields of deep learning. We used deep learning to perform classification diagnosis in oral exfoliative cytology and to analyze performance, using SAM as an optimization algorithm to improve classification accuracy. The whole image of the oral exfoliation cytology slide was cut into tiles and labeled by an oral pathologist. CNN was VGG16, and stochastic gradient descent (SGD) and SAM were used as optimizers. Each was analyzed with and without a learning rate scheduler in 300 epochs. The performance metrics used were accuracy, precision, recall, specificity, F1 score, AUC, and statistical and effect size. All optimizers performed better with the rate scheduler. In particular, the SAM effect size had high accuracy (11.2) and AUC (11.0). SAM had the best performance of all models with a learning rate scheduler. (AUC = 0.9328) SAM tended to suppress overfitting compared to SGD. In oral exfoliation cytology classification, CNNs using SAM rate scheduler showed the highest classification performance. These results suggest that SAM can play an important role in primary screening of the oral cytological diagnostic environment.
