Background:
This study examined the distribution of stress-cortisol responses and risk factors affecting perceived stress and cortisol responses among 187 university students in South Korea.
Methods:
Perceived stress, depressive symptoms, and health-promoting lifestyle were assessed using structured questionnaires. Blood analyses and anthropometrics were used to determine cortisol and cardiometabolic risks. Multinomial logistic regression analysis was used to examine the factors affecting stress-cortisol responses.
Results:
Four groups of stress-cortisol responses were found, including normal (39.0%), high stress (34.8%), high stress-cortisol (13.9%), and high cortisol group (12.3%). Age, systolic blood pressure, high-density lipoprotein cholesterol, depressive symptoms, and physical activity were associated with stress-cortisol responses.
Conclusions
Multidimensional interventions are needed to reduce stress levels and promote normal stress-cortisol responses.

OBJECTIVE: Upper paraaortic lymph node dissection (UPALD) to the infrarenal level is one of the most challenging robotic procedures. Because robotic system has the limitation in robotic arm mobility. This surgical video introduces a novel robotic approach, lower pelvic port placement (LP3), to perform optimally and simultaneously both UPALD and pelvic procedures in gynecologic cancer patients using da Vinci Xi system. METHODS: The patient presented with high-grade endometrial cancer. She underwent robotic surgical staging operation. For the setup of the LP3, a line was drown between both anterior superior iliac spines. At 3 cm below this line, another line was drown and four robotic ports were placed on this line. RESULTS: After paraaortic lymph node dissection (PALD) was completed, the boom of robotic system was rotated 180° to retarget for the pelvic lateral displacement. Robotic ports were placed and docked again. The operation was completed robotically without any complication. CONCLUSION: The LP3 was feasible for performing simultaneously optimal PALD as well as procedures in pelvic cavity in gynecologic cancer patients. The advantage of LP3 technique is the robotic port placement that affords for multi-quadrant surgery, abdominal and pelvic dissection. The LP3 is facilitated by utilizing advanced technology of Xi system, including the patient clearance function, the rotating boom, and ‘port hopping’ that allows using every ports for a camera. The LP3 will enable surgeons to extend the surgical indication of robotic surgical system in the gynecologic oncologic field.

Dengue fever is one of the commonest tropical disease in
the tropics. It can present with mild acute febrile illness to
severe organ failure. Reported neurological complications
of dengue include dengue encephalopathy, encephalitis,
transverse myelitis and intracranial haemorrhage.
Intracranial haemorrhage in dengue can present as subdural
haematoma, extradural haematoma, intracerebral
haemorrhage and subarachnoid haemorrhage. We report
here a case of subarachnoid haemorrhage in a patient with
severe dengue. Our patient was a 30-year-old man who
presented with acute febrile illness. He subsequently
developed plasma leakage and upper gastrointestinal
bleeding. He then had reduced conscious level. Computed
tomography of his brain showed subarachnoid
haemorrhage. He eventually succumbed to his illness.

Objective:
Patients with severe symptomatic aortic stenosis are assessed for coronary artery disease (CAD) prior to transcatheter aortic valve implantation (TAVI) with treatment implications. Invasive coronary angiography (ICA) is the recommended modality but is associated with peri-procedural complications. Integrating machine learning (ML)-based computed tomography-derived fractional flow reserve (CT-FFR) into existing TAVI-planning CT protocol may aid exclusion of significant CAD and thus avoiding ICA in selected patients.
Materials and Methods:
A single-center, retrospective study was conducted, 41 TAVI candidates with both TAVI-planning CT and ICA performed were analyzed. CT datasets were evaluated by a ML-based CT-FFR software. Beta-blocker and nitroglycerin were not administered in these patients. The primary outcome was to identify significant CAD. The diagnostic performance of CT-FFR was compared against ICA.
Results:
On per-patient level, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy were 89%, 94%, 80%, 97% and 93%, respectively. On per-vessel level, the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 75%, 94%, 67%, 96% and 92%, respectively. The area under the receiver operative characteristics curve per individual coronary vessels yielded overall 0.90 (95% confidence interval 85%–95%). ICA may be avoided in up to 80% of patients if CT-FFR results were negative.
Conclusion
ML-based CT-FFR can provide accurate screening capabilities for significant CAD thus avoiding ICA. Its integration to existing TAVI-planning CT is feasible with the potential of improving the safety and efficiency of pre-TAVI CAD assessment.
