Objective: To analyze the epidemiological features of the index cases of severe acute respiratory syndrome (SARS) occurred in different cities in Guangdong province and to trace for the source of infection.
Methods: Standardized individual case inventory was adopted to conduct investigation on index cases and on persons who had close contact with index cases in Guangdong province. Data on the epidemiological characteristics, secondary cases and the links among index cases were analyzed.
Results: Between November 16, 2002 and April 16, 2003, there had been 13 index cases of SARS including 3 cadres, 3 farmers, 2 retirees, 2 workers and 1 shop attendant, reported from 13 cities in Guangdong province. Between November 2002 and January 2003, there had been 7 cities reported to have identified index cases of SARS with 6 of them being infected in their own cities and 1 imported from Guangzhou city. All of the cases had no close contacts to similar patients but 6 of them later caused 2nd or even 3rd generation cases of SARS. Most cases hit young people (7/13) with a sex ratio of 1:0.6. The fatality rate of index cases was high (4/13).
Conclusion: No evidence showed that there was direct transmission among the index cases. Data regarding the geographical origin of those index cases led to the assumption that the infection had started in six cities of Pearl river delta region and the Hong Kong Special Administrative Region.

Feasibility of on-site CT-FFR analysis on cardiac photon-counting CT in evaluation of hemodynamically significant stenosis in comparison to invasive catheter angiography.

Objectives: Coronary CT angiography (CCTA) is an excellent tool in ruling out coronary artery disease (CAD) but tends to overestimate especially highly calcified plaques. To reduce diagnostic invasive catheter angiographies (ICA), current guidelines recommend CT-FFR to determine the hemodynamic significance of coronary artery stenosis. Photon-Counting Detector CT (PCCT) revolutionized CCTA and may improve CT-FFR analysis in guiding patients.

Background: Surgical site infection (SSI) is a significant complication following pediatric cardiovascular surgery. Although drain tip cultures (DTC) are sometimes used postoperatively to predict SSIs, their diagnostic value in pediatric cardiovascular surgery remains unclear. This study aimed to assess the diagnostic utility of DTC for predicting SSIs in pediatric cardiovascular surgery patients.

Objective: The potential of robot-assisted (RA) single-position (SP) lateral lumbar interbody fusion (LLIF) warrants further investigation. This study aimed to assess the efficacy of RA-SP-LLIF in improving both clinical and radiographic outcomes in patients undergoing lumbar spinal fusion surgery.
Methods: A total of 59 patients underwent either RA-SP-LLIF (n = 31 cases) or traditional LLIF (n = 28 cases).

Common early childhood concerns and behaviors include sleep issues, thumb-sucking, pacifier use, picky eating, school readiness, and oral health. Family physicians must recognize when these indicate an underlying disorder and offer constructive and evidence-based strategies to support healthy child development and family well-being. Behavioral interventions and education to address sleep issues can alleviate stress and decrease fatigue for the whole family.

Background: Teaching severe pelvic trauma poses a significant challenge in orthopedic surgery education due to the necessity of both clinical reasoning and procedural operational skills for mastery. Traditional methods of instruction, including theoretical teaching and mannequin practice, face limitations due to the complexity, the unpredictability of treatment scenarios, the scarcity of typical cases, and the abstract nature of traditional teaching, all of which impede students' knowledge acquisition.
Objective: This study aims to introduce a novel experimental teaching methodology for severe pelvic trauma, integrating virtual reality (VR) technology as a potent adjunct to existing teaching practices.
