Abstract
Arrhythmia, a frequently encountered and life-threatening cardiac disorder, can manifest as a transient or isolated event. Traditional automatic arrhythmia detection methods have predominantly relied on QRS-wave signal detection. Contemporary research has focused on the utilization of wearable devices for continuous monitoring of heart rates and rhythms through single-lead electrocardiogram (ECG), which holds the potential to promptly detect arrhythmias. However, in this study, we employed a convolutional neural network (CNN) to classify distinct arrhythmias without QRS wave detection step. The ECG data utilized in this study were sourced from the publicly accessible PhysioNet databases. Taking into account the impact of the duration of ECG signal on accuracy, this study trained one-dimensional CNN models with 5-s and 10-s segments, respectively, and compared their results. In the results, the CNN model exhibited the capability to differentiate between Normal Sinus Rhythm (NSR) and various arrhythmias, including Atrial Fibrillation (AFIB), Atrial Flutter (AFL), Wolff-Parkinson-White syndrome (WPW), Ventricular Fibrillation (VF), Ventricular Tachycardia (VT), Ventricular Flutter (VFL), Mobitz II AV Block (MII), and Sinus Bradycardia (SB). Both 10-s and 5-s ECG segments exhibited comparable results, with an average classification accuracy of 97.31%. It reveals the feasibility of utilizing even shorter 5-s recordings for detecting arrhythmias in everyday scenarios. Detecting arrhythmias with a single lead aligns well with the practicality of wearable devices for daily use, and shorter detection times also align with their clinical utility in emergency situations.

Abstract
BACKGROUND Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has greater reproducibility than LDI. This study investigated the use of LSCI in the evaluation and treatment of six patients who developed vascular complications after facial dermal filler injections. METHODS The areas of vascular occlusion were accurately defined in real time by LSCI and were more precise than visual inspections or photographic evidence for guiding needling and hyaluronidase treatment. RESULTS All patients had achieved satisfactory outcomes as early as Day 2 of treatment and no procedure-related complications were reported after a median follow-up of 9.5 (7-37) days. CONCLUSION LSCI accurately and noninvasively delineated vascular occlusions in real time among patients experiencing complications of facial dermal filler injections. Moreover, LSCI was more accurate than visual and photographic evaluations. Clinicians can use LSCI to reliably follow-up therapeutic outcomes after salvage interventions for vascular occlusions.

Abstract
Background and Objectives: Psoriasis is a chronic, long-term, incurable skin inflammatory disease characterized by the excessive proliferation of epidermal keratinocytes, dilation of blood vessels, thickening of the skin, and the formation of visible red patches of variable sizes. The impact on patients differs with the severity of the disease, leading to physiological discomfort and psychological distress, which significantly affect the quality of life. The etiology of psoriasis is not completely clear, but immune cells, including type 1 and type 17 cytokine-producing cells modulated by regulatory T cells (Tregs), play a critical role in driving the disease pathogenesis. With the ability to specifically target inflammatory markers, biologics can efficiently inhibit the spread of inflammation to achieve therapeutic effects. The goal was to explore the changes in body image and quality of life in psoriasis patients undertaking therapies with biologic agents. Materials and Methods: This study employed a quasi-experimental, single-sample, pretest-posttest design. Forty-four psoriasis patients were recruited from the dermatology outpatient clinics at two medical centers in northern Taiwan. A structured questionnaire, including demographic information, the Body Image Scale (BIS), and the Dermatology Life Quality Index (DLQI), was used as a research tool. Questionnaire assessments were conducted both before and three months after the biologic agent intervention. Statistical analyses were performed using SPSS version 22.0. Results: Our results indicated a significant difference in body image between psoriasis patients before and after intervention with biologic agents. In addition, overall quality of life (QoL) also showed significant improvements before and after biologic agent intervention. There was a positive correlation between body image and quality of life in psoriasis patients. Conclusions: The treatment for psoriasis has evolved rapidly in recent years, and biologic agents have proven to be effective therapies to improve the quality of life for psoriasis patients. Our study suggests that health-related education and psychological support can further benefit psoriasis patients to willingly and positively undertake treatment and therefore improve their positive body image and quality of life.

Abstract
Objective: Patients with advanced sarcomas have a dismal prognosis with few effective therapies. The purpose of this study was to evaluate the efficacy and safety of anlotinib in the treatment of advanced sarcoma and to explore the relationship between adverse events (AEs) and efficacy. Methods: Data from 45 advanced sarcoma patients who received anlotinib monotherapy at Affiliated Cancer Hospital of Zhengzhou University between June 2018 and August 2021 were retrospectively analyzed. According to Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1, the objective remission rate (ORR) and disease control rate (DCR) were calculated, and the progression free survival (PFS) and treatment-related AEs were recorded and analyzed. Survival analysis was conducted using the Kaplan-Meier survival rates were compared using the Log rank test. Results: Forty patients were treated for more than 1.5 months and received efficacy evaluation. The ORR and DCR after 3 months were 7.5%(3/40) and 80.0%(32/40), respectively. The overall ORR was 2.5%(1/40), the total DCR was 27.5%(11/40), and the median progression-free survival (m-PFS) was 6.70 months; The m-PFS of alveolar soft tissue sarcoma (ASPS) was 10.27 months, which was significantly longer than that of other subtypes of sarcoma (P=0.048). In addition, the DCR of ASPS and synovial sarcoma (SS) was significantly better than that of osteosarcoma (P<0.05). The most common AEs were elevated thyroid stimulating hormone (17.8%, 8/45), anemia (15.6%, 7/45), fatigue (11.1%, 5/45). Five patients developed grade 3 AEs after treatment; The PFS of patients with hand-foot syndrome after treatment was significantly longer than that of patients without hand-foot syndrome (14.10 vs 6.00, P=0.024). Conclusions: The efficacy of anlotinib in the treatment of ASPS and SS is better than that of other subtypes. The PFS in the group with hand-foot syndrome was significantly longer than that of the group without hand-foot syndrome.

Abstract
Objective: To explore the possible clinical benefits of CT/MRI image fusion and computer-assisted simulation techniques in guiding type Ⅲ and Ⅳ primary pelvic bone tumor surgeries. Methods: The clinic data of primary bone sarcomas patients treated at Department of Bone and Soft Tissue,Zhenghzhou University Affiliated Cancer Hospital from January 2019 to December 2021 were retrospectively analyzed. Based on whether the CT and MRI image fusion technique was utilized for tumor evaluation and surgical planning,the patients were divided into image fusion group (n=21) or control group (n=27). There were 7 male and 14 female patients included in the image fusion group, with the age of (37.0±10.4) years(range: 18 to 67 years). In the control group, there were 10 males and 17 females with the age of (39.7±15.2) years (range: 16 to 65 years). Both groups included osteosarcoma,chondrosarcoma and undifferentiated polymorphic sarcoma as the pathological diagnosis. Clinical information such as gender,age,pathological diagnosis,location of disease,and metastasis at diagnosis were collected. Surgical related information such as duration of surgery,blood loss,surgical margin,and wound complications were also obtained. Periodical follow-ups every 3 months were performed for all patients to monitor the status of local recurrence,distant metastasis,and survival information. Independent t test and χ² test were used for data comparison between groups. Results: Significant reduced duration of surgery was observed in the image fusion group in comparison with control group both in type Ⅲ and Ⅳ surgeries ((144.0±31.6)min vs. (248.2±56) min,t=-8.084, P<0.01); (173.0±42.0)min vs. (306.1±62.0)min, t=-4.518, P<0.01). Blood loss was significantly reduced in the image fusion group compared with the control group ((484.8±226.3)ml vs. (836.1±359.8)ml,t=-4.130, P<0.01). In addition, significant lower ratio of R1 margin and recurrence rates of type Ⅲ and Ⅳ surgeries were found in the image fusion group comparing with the control group (4.8%(1/21) vs. 22.2%(6/27), χ²=4.214, P=0.040; 4.8%(1/21) vs. 22.2%(6/27), χ²=4.214, P=0.040).In the image fusion group, there were 3 cases of incision infection, 1 of which underwent secondary debridement.And in thecontrol group there were 7 cases of incision infection, 3 of which underwent secondary debridement. There was no significant difference in the incidence of complications between the two groups (14.2%(3/21)vs. 25.9%(7/27), χ²=0.645, P=0.422). Up to the last follow-up, 1 patient died in the image fusion group and 2 patients died in the control group, the difference was not statistically significant (χ²=1.885, P=0.220). Conclusion: Compared with the traditional operation,the image fusion technique can significantly reduce the duration of surgery,blood loss and lower the recurrence rate by achieving better surgical margins.

Abstract
Abstract
Background
Reuse of cardiac implantable electronic devices (CIEDs) can reduce the cost of using these expensive devices. However, whether resterilized CIEDs will increase the risk of reinfection in patients with previous device infection remains unknown. The aim of the present study is to compare the reinfection rates in patients who had initial CIED infection and underwent reimplantation of resterilized CIEDs or new devices.
Methods
Data from patients with initial CIED infection who received debridement of the infected pocket and underwent reimplantation of new or resterilized CIEDs at MacKay Memorial Hospital, Taipei, Taiwan, between January 2014 and June 2019 were retrospectively analyzed. Patient characteristics, relapse rates of infection, and potential contributing factors to the infection risk were examined.
Results
Twenty-seven patients with initial CIED infection and reimplanted new CIEDs (n = 11) or resterilized CIEDs (n = 16) were included. During the 2-year follow-up, there were 1 (9.1%) and 2 (12.5%) infection relapses in the new and resterilized CIED groups, respectively. No relapse occurred for either group if the lead was completely removed or cut short. The median duration between debridement and device reimplantation in patients with infection relapse vs patients without relapse was 97 vs 4.5 days for all included patients, and 97 vs 2 days and 50.5 vs 5.5 days for the new and resterilized CIED groups, respectively.
Conclusions
Subpectoral reimplanting of resterilized CIEDs in patients with previous device infection is safe and efficacious. With delicate debridement and complete extraction of the leads, the CIED pocket infection relapse risk can be greatly decreased.

Few studies have assessed the efficacy and safety of reconstruction of sternal infection using a pectoralis muscle flap combined with a rectus abdominis muscle (RAM) sheath fasciocutaneous flap. We report here our experience with this procedure to reconstruct the sternal defect in patients (n = 46) with a deep sternal wound infection (DSWI) after cardiac surgery. After wound reconstruction, the proportion of prolonged mechanical ventilation use and intensive care unit (ICU) stay were 17.4% (n = 8) and 21.7% (n = 10), respectively. The 30‐day all‐cause mortality was 15.2%; recurrence rate was 17.4%; postoperative complications were 15.2%; and median hospital stay was 31 (0‐157) days. Multivariate logistic regression analysis revealed that hypertension (β = 21.32, 95%CI 4.955‐37.68, P = .014), drainage‐tube use (β = 0.944, 95%CI 0.273‐1.614, P = .008), and prolonged intensive care unit stay (β = 53.65, 95%CI 31.353‐75.938, P < .001) were significantly correlated with hospital stay. In conclusion, a procedure including surgical debridement, sternal reconstruction with bilateral PM and RAM sheath flap, long‐term antibiotics, and adequate drainage is a beneficial technique in the reconstruction of deep sternal wound infection after cardiac surgery. Duration of drainage tube use may be as an index for a hospital stay or wound healing.

Abstract
ABSTRACT Kimura disease (KD) is a rare, chronic inflammatory disorder presenting with solitary or multiple masses. Treatment options include surgical excision, corticosteroids, and radiotherapy; however, optimal therapy remains to be established. Moreover, efficacy of a humanized monoclonal antibody, dupilumab (Dupixent), requires to be demonstrated. Here, we present a 36-year-old male patient with an enlarging mass in the left medial thigh and chronic eczema over the abdomen and lower legs. Kimura disease was diagnosed after surgical excision. Postoperative treatment with dupilumab was applied with an initial dose of 600 mg followed by 300 mg every 2 weeks for 8 months. No recurrence of KD was observed in the 1-year follow-up. The eczematous lesions improved greatly. To our knowledge, this is the first report of using dupilumab for treating KD.

Abstract
Vascular occlusion is a rare but severe complication of dermal filler injections. Early treatment of this complication produces better outcomes. Current diagnostic methods for vascular occlusion in the skin are subjective and imprecise; these include capillary refill time, skin color, and reports of pain. This study aimed to assess the use of laser Doppler imaging (LDI) in the evaluation and treatment of vascular complications caused by dermal filler injections. This retrospective study used laser Doppler imaging (LDI) in 13 patients who developed vascular occlusion after facial dermal filler injections, with subsequent follow-up. The precise areas of perfusion observed on LDI were compared with the findings of clinical and photographic evaluation. The results showed that LDI accurately identified areas of vascular occlusion and improved treatment precision among these thirteen patients. The procedure was more precise than visual inspection or photographic evidence. Satisfactory outcomes were achieved for all patients, and no procedure-related complications were reported. Collectively, LDI provides fast, noninvasive, and accurate delineation of areas of vascular occlusion caused by complications of dermal filler injections and avoids several subjective shortcomings of visual and photographic evaluations. Thus, LDI effectively tracks treatment outcomes. However, large-scale studies are required to confirm the present findings.

Abstract
ABSTRACT The Morel-Lavallée lesion (MLL) is a posttraumatic close degloving injury, which is often underdiagnosed at first. Patients with MLLs usually present with tender and enlarging soft tissue swelling with fluctuation, decreased skin sensation, ecchymosis, or even skin necrosis hours to days after the inciting injury. The lesion can lead to intractable morbidity if it remains untreated. There is no consensus regarding the treatment for MLL at present. Here, we report an MLL in the pretibial region of a 43-year-old woman who experienced a low-energy contusion in a motorbike accident. The pretibial lesion was diagnosed using sonography and fine-needle aspiration. We successfully treated the patient by performing percutaneous debridement via a small incision and injections of fibrin after conservative treatment failed. The method we herein propose achieved the goal of open surgical debridement, providing faster recovery and a high degree of patient comfort. We reviewed the available pertinent literature and propose our own treatment protocol with the aim to establish common therapies ofMLL.

Abstract
The relatively new medial sural artery perforator flap is increasingly being used for reconstruction. However, muscle necrosis of the medial head of gastrocnemius after MSAP flap harvest is a previously unnoticed early complication of the donor site. We present two cases of MSAP flap reconstruction that developed this early complication.
