To investigate the differences in postoperative short-term complications and long-term prognosis of pancreatic cancer(PC) patients after total pancreatectomy(TP) and pancreaticoduodenectomy(PD).

Abdominal surgery as a common type of clinical surgery, postoperative treat-ment and rehabilitation has always been the focus of surgeons. Somatostatin drugs are commonly used for postoperative bleeding, portal hypertension bleeding, and prophylactic treatment of com-plications such as acute pancreatitis. However, the standardized application of somatostatin still faces numerous challenges in clinical practice. The famous experts and their teams in the field of digestive surgery, medical insurance expert and lawyer, combined with the experience of their respective centers, under the new national medical insurance policy, explore the significance of treatment and rehabilitation after abdominal surgery and the application strategy of somatostatin drugs from different angles. Professor Zhang Taiping succinctly explained the incidence and harm of gastro-intestinal fistula, pointing out that "how to heal the fistula in a short time" is the main rehabilitation goal and the treatment is mainly comprehensive treatment. Professor Chen Chaowu comprehen-sively introduces diagnostic and treatment processes for several representative cases encountered in clinical practice while sharing his team′s rich clinical experience and posing reflective questions. Professor Li Fei starts with practical cases, focusing on duodenal fistula, including fistula caused by complications after endoscopic retrograde cholangiopancreatography, with special emphasis on Stanford classification and different types of treatment. Ms. Zhang Qun interprets national medical insurance policies. She emphasizes the significance of supervising medical insurance funds and shares experiences related to issues regarding autonomous management by healthcare institutions. Lawyer Li Hongqi provides comprehensive suggestions on rational use of drug based on policy guidance and practical cases.

Objective To explore the application value of deep learning image reconstruction(DLIR)with coronary computed tomography angiography(CCTA)using 100 kV.Methods Sixty patients who underwent CCTA were selected.The tube voltage of 100 kV,noise index of 24 were applied.The 60％adaptive statistical iterative reconstruction-Veo(ASIR-V)and DLIR-low(DLIR-L),DLIR-medium(DLIR-M)and DLIR-high(DL1R-H)were reconstructed.The CT values and standard deviation(SD)values of the aortic root,left main artery,left anterior descending artery,left circumflex artery,right coronary artery and pericardial fat of the four groups of images were measured,and the signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated.Two radiologists with five-year working experience subjectively evaluated the image quality using a five-point method double-blindly.Results The differences in noise(SD values),SNR values and CNR values among the four groups of images were statistically significant(P＜0.001).As the reconstruction gradually changed of 60％ASIR-V,DLIR-L,DLIR-M and DLIR-H,the coronary SD values gradually decreased,while the SNR values and CNR values gradually increased,among which the DLIR-H had the lowest SD values and the highest SNR values and CNR values.The subjective scores of the four groups of images by two radiologists showed good consistency(Kappa value=0.929,P＜0.001),and the subjective scores were all above 3 points which met the clinical diagnosis criteria.The subjective scores of DLIR-L,DLIR-M and DLIR-H were significantly higher than those of 60％ASIR-V(P＜0.001),with the DLIR-H achieving the highest subjective score.Conclusion DLIR can significantly reduce image SD value and improve image quality of CCTA with 100 kV,among which DLIR-H has the best effect on improving CCTA image quality.

Objective:To discuss the performance of visual score and heart-to-contralateral lung (H/CL) ratio of 99Tc m-pyrophosphate (PYP) SPECT/CT scintigraphy for diagnosing transthyretin-related cardiac amyloidosis (ATTR-CA) by using Meta-analysis. Methods:Relevant studies on 99Tc m-PYP SPECT/CT diagnosis of ATTR-CA published before August 20, 2023 from databases including Pubmed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang and China Science and Technology Journal Database (VIP) were retrieved. Articles were screened and indices which reflect the diagnostic efficiency such as sensitivity and specificity were extracted. Forest plots were drawn, and subgroup analysis was performed to analyze the heterogeneity. Results:A total of 160 articles were retrieved, and 11 articles involving 1 802 patients were enrolled, of whom 605 were diagnosed with ATTR-CA. All 11 articles were enrolled when analyzing the diagnostic efficiency of visual score for diagnosing ATTR-CA. After integration, the sensitivity and specificity were 0.95(95% CI: 0.91-0.97) and 0.95(95% CI: 0.90-0.98), respectively. Ten articles (1 611 patients) were enrolled when analyzing the diagnostic efficiency of H/CL ratio for diagnosing ATTR-CA. After integration, the sensitivity and specificity were 0.93(95% CI: 0.82-0.98) and 0.99(95% CI: 0.90-1.00), respectively. Subgroup analysis indicated that lack of uniformity in diagnostic criteria was the primary source of heterogeneity. Conclusion:99Tc m-PYP SPECT/CT scintigraphy exhibits high diagnostic efficiency for ATTR-CA.

Purpose To investigate the feasibility of CT-based feature tracking technology to quantify left ventricular myocardial strain(MS)and its significance in hypertrophic obstructive cardiomyopathy(HOCM).Materials and Methods A total of 35 HOCM patients who underwent cardiac coronary angiography from March 2019 to December 2021 in the First Affiliated Hospital of the Air Force Military Medical University were retrospectively included,and a total of 60 cases who were negative for cardiac coronary angiography among those who visited the hospital with suspected coronary artery disease were randomly enrolled.Conventional cardiac functional parameters and MS parameters were quantified via post-processing software,and differences of parameters between the groups were analyzed.The diagnostic efficacy of MS parameters for HOCM was further evaluated.Results Compared to the control group,the HOCM group exhibited significant increases in various conventional left ventricular functional parameters,including left ventricular wall thickness,mass,mass index,end-diastolic volume and stroke volume(t=2.119 to 24.861,all P<0.05).However,there were no statistically significant differences in end-systolic volume and cardiac output between the two groups(P>0.05).The global longitudinal and radial strain values of HOCM group were significantly lower than those of control group(t=12.857,-6.427,P<0.01),while the endocardial global circumferential strain of HOCM group was significantly higher than that of control group(t=-2.369,P<0.05).Among MS parameters,global longitudinal strain exhibited the best diagnostic efficacy for HOCM,with an area under the curve of 0.997.A cutoff value of≤20.78%for global longitudinal strain showed that the sensitivity and specificity was 100%and 95%,respectively.Conclusion The MS parameters quantified by the CT-based feature tracking technique are superior to left ventricular ejection fraction in quantifying left ventricular function,with the highest sensitivity and specificity for early myocardial function impairment of longitudinal strain.In addition,the technique has good repeatability and is expected to become a new indicator for the assessment of myocardial function in HOCM.

Aneurysms and pseudoaneurysm are commonly encountered with arteriovenous vascular access for haemodialysis. They are difficult complications to manage. Due to the limited number of vascular centers available, patients were unable to seek treatment until further complications arise. The technique of partial aneurysmectomy and primary repair was adopted as the method of repair in this study. A total of 20 cases underwent the surgery from 2019 to 2020. Among the 20 cases, one patient had two pseudoaneurysms at different location which requires her to undergo the procedure twice. The successful cannulation rate post repair was 70% whereas the overall complication rate was 35% which might be attributed to the small sample size. Overall, this study demonstrated that AVF aneurysm and pseudoaneurysm can be safely treated with this approach and can be done effectively in non-vascular centers by general surgeons.

A 78-year-old post-stroke man with multiple comorbidities who was activity of daily living-dependent developed aspiration pneumonia associated with nasogastric tube (NGT) blockage. He presented with malnutrition and risk of sarcopenia with hypoalbuminaemia, small calf circumference (CC), low body mass index and small mid upper arm circumference. He showed symptoms of moderate-to-severe vascular dementia with behavioural psychological stress disorder, resulting in carer stress. Psychoeducation among the carers and referral to a neuro-psychiatrist were ensued after outpatient-based team meeting discussion. Herein, we highlight the importance of screening for sarcopenia and nutritional status in post-stroke patients with the use of the CC and serum albumin level as well as the involvement of a multidisciplinary team in the primary care setting to improve patient outcomes. Percutaneous endoscopic gastrostomy tubes are more suitable than NGTs for post-stroke patients who require enteral feeding to improve the nutritional status.

Introduction: Erectile dysfunction (ED) is common in men with diabetes and is associated with coronary artery disease and psychological distress. However, discussion of ED in primary care consultations is uncommon. Interventions, such as audit and feedback, mandate of management, and workshop on men’s sexual health, have been proposed to improve ED screening in public health clinics. This study aimed to pilot test a multi-faceted intervention to increase ED screening among men with diabetes and to improve knowledge and confidence in ED screening among primary healthcare providers (PHPs). Methods: We conducted an interrupted time-series quasi-experimental study with PHPs at public health clinics in Perak, Malaysia from February 2019 to February 2020. Doctors, nurses, and assistant medical officers involved in diabetes care were recruited. The intervention was conducted between July and September 2019 and comprised two phases: audit and feedback, and mandate from management (phase 1), and an interactive face-to-face workshop (phase 2). The primary outcome measure was monthly ED screening rate, and the data were retrieved from health records and the clinical diabetes registry. The PHPs completed a questionnaire on ED knowledge and confidence in ED screening before and after the workshop. Results: The total number of attendances by patients with diabetes was 50,325 during the study period, of which 21,413 were by men. A total of 30 PHPs participated in the training workshop: 7 (23.3%) doctors, 12 (40%) medical assistants, and 11 (36.7%) nurses. The mean duration of employment at a health clinic was 7 ± 5 years. The majority of the participants were male (56.7%), Malay (80%), married (76.7%), and had no experience with working in a urology department (76.7%). There was a significant improvement in the mean knowledge score (39.0 ± 11.4 vs. 63.6 ± 6.2, p<0.001) and median confidence level in ED screening from 2 (IQR 2–3) to 4 (IQR 4–4) after the workshop (p<0.001). After phase 1, the rate of ED screening increased from a baseline of between 10.3% (February 2019) and 12.7% (June 2019) before intervention to between 15% (July 2019) and 18.9% (September 2019) and was maintained between 18% (October 2019) and 17.9% (December 2019) after phase 2. Subsequently, the ED screening rate declined from 14.6% (January 2020) to 10.9% (February 2020). Conclusion This study found that audit and feedback with mandate from management increased ED screening and detection rate. The workshop improved the participants’ knowledge and confidence in ED screening but did not further increased ED screening. The improved practice was sustained for 6 months after the intervention, while the detection rate of ED persisted. We propose regular audit and feedback with mandate from management to sustain the practice of ED screening in men with diabetes.

Introduction: Obesity is associated with an increased risk for non-communicable diseases. Local studies have shown that 33.1% of healthcare providers (HCPs) are overweight, while 21.1% are obese. Interventions that consist of diet, physical exercise and cognitive behavioural training have been shown to be successful in reducing weight. Methods: We designed a weight loss programme for our HCPs named the ‘Fit and Trimmed Staff’ programme, which consisted of 3 months of group education on obesity-related health problems led by a doctor, a pharmacist, a nutritionist and an occupational therapist among HCPs. Monthly individual dietary counselling by a nutritionist was also provided for 6 months. We measured the body weight, body mass index, percentage of body fat, visceral fat and percentage of skeletal muscle of the HCPs before and after the intervention. Results: Forty-five (56.25%) HCPs at Simpang Health Clinic were either overweight or obese; the majority of them were drivers and administrative clerks (100%), followed by health attendants (69.2%) and medical assistants (63.6%). At 6 months post-intervention, there was a trend towards a non-significant reduction in the fat percentage (median=-0.8%, P=0.423). Approximately 42% (n=19) of the HCPs lost weight, while 58% gained weight. Weight loss was observed more commonly in the male HCPs (>50%) than in the female HCPs. Conclusion A weight loss programme solely consisting of health discussion and nutritional advice is inadequate to induce weight reductions. A multimodal approach may be considered in managing weight among HCPs.
