Objective: To determine whether patients with obstructive sleep apnoea (OSA) have an increased risk of aortic aneurysm (AA). Methods: The data for the nationwide population-based retrospective cohort study described here were obtained from the Taiwan National Health Insurance Research Database (NHIRD). We selected adult patients who had been newly diagnosed as having OSA and were followed up between 2000 and 2010. We excluded patients who had been diagnosed as having AA before the date of the new OSA diagnosis. The control cohort consisted of individuals who had no OSA history. The patients and the control cohort were selected by 1: 4 matching according to the following baseline variables: sex, age, index year, and comorbidities. The outcome measure was AA diagnosis. Results: In total, 31,274 patients diagnosed as having OSA were identified. Compared to patients without OSA, they had no significantly discrepant cumulative risk of developing AA in subsequent years (p from log-rank test = 0.442). We used the Cox proportional-hazards regression model, which found that only male sex, older age, diabetes mellitus, chronic obstructive pulmonary disease (COPD), and coronary artery disease were independently associated with AA occurrence among subjects with an OSA diagnosis. OSA was not associated with AA development. On the other hand, in the subgroup of COPD, patients with OSA had a higher incidence of risk of AA than those without OSA. Conclusion: When compared to those without OSA, patients with OSA do not have an increased AA risk.

Background Obesity has been indicated to be a risk factor of diverticulosis. However, plausible relationship remained controversial. This cross-sectional study elucidated the association between percentage of body fat and the risk of diverticulosis. Methods The study was conducted at a single medical center in Taiwan from 2000–2016 which enrolled 5557 adults with age above 20 years old receiving a health examination including self-reported questionnaires, measurement of percentage of body fat (PBF), blood test and colonoscopy at the Tri-Service General Hospital (TSGH). Logistic regressions were used to analyze the association between PBF and diverticulosis. Further stratification of participants was based on age and gender and three extended models were established for multivariable adjustment. Results 243 of 3141 males and 103 of 2416 females were diagnosed with having diverticulosis. After covariates adjustment, only participants in the highest quartile of PBF (Q4 ≥33.8%) showed significantly positive association with the risk diverticulosis (OR 2.089, p <0.001). In subgroup analysis, the odds ratio for having diverticulosis in females was significantly higher than in males. In addition, We found that the odds ratio of having diverticulosis was higher in the group older than 60 years old compared to the younger group (OR 1.052; p<0.001; OR 1.043; p<0.001). Conclusions In conclusion, PBF was a potential risk factor of diverticulosis. Individuals with higher PBF exhibits increased risk of diverticulosis, especially in females. Furthermore, bioelectrical impedance analysis may create a simple, available and radiation-free way to assess the risk of diverticulosis.

Guillain–Barré syndrome (GBS) is an acute neuroimmunological disorder characterized by rapidly ascending symmetrical limb weakness, areflexia, and sensory deficits. Approximately 65% of patients with GBS present with autonomic dysfunction, which commonly occurs in advanced stages. However, paralytic ileus, a sign of gastrointestinal dysautonomia, is rare as the presenting feature in GBS before motor weakness becomes evident. We report the case of a 54-year-old man admitted to the Emergency Department with paralytic ileus as the prodromal feature in early-stage GBS. Total parenteral feeding and prokinetic use were initiated, but no clinical improvement was observed. The patient showed rapid progression to quadriplegia, which was ultimately determined to be respiratory muscle failure requiring mechanical ventilation and intensive care unit admission. He underwent 5 days of intravenous immunoglobulin therapy and muscle strength was partially improved thereafter. However, the patient’s enteral nutritional support was undesirable because of persistent poor gastric emptying complicated by fungemia and profound sepsis throughout the hospital course. Finally, he died 1 month after admission. Ignorance of this unusual prodrome to GBS could result in delayed treatment, along with potential progression to life-threatening events. Early recognition of GBS and prompt immunotherapy are critical for reducing morbidity and mortality.

Patients bitten by Protobothrops mucrosquamatus typically experience significant pain, substantial swelling, and potentially blister formation. The appropriate dosage and efficacy of FHAV for alleviating local tissue injury remain uncertain. Between 2017 and 2022, 29 snakebite patients were identified as being bitten by P. mucrosquamatus. These patients underwent point-of-care ultrasound (POCUS) assessments at hourly intervals to measure the extent of edema and evaluate the rate of proximal progression (RPP, cm/hour). Based on Blaylock’s classification, seven patients (24%) were classified as Group I (minimal), while 22 (76%) were classified as Group II (mild to severe). In comparison to Group I patients, Group II patients received more FHAV (median of 9.5 vials vs. two vials, p-value < 0.0001) and experienced longer median complete remission times (10 days vs. 2 days, p-value < 0.001). We divided the Group II patients into two subgroups based on their clinical management. Clinicians opted not to administer antivenom treatment to patients in Group IIA if their RPP decelerated. In contrast, for patients in Group IIB, clinicians increased the volume of antivenom in the hope of reducing the severity of swelling or blister formation. Patients in Group IIB received a significantly higher median volume of antivenom (12 vials vs. six vials; p-value < 0.001) than those in Group IIA. However, there was no significant difference in outcomes (disposition, wound necrosis, and complete remission times) between subgroups IIA and IIB. Our study found that FHAV does not appear to prevent local tissue injuries, such as swelling progression and blister formation, immediately after administration. When administering FHAV to patients bitten by P. mucrosquamatus, the deceleration of RPP may serve as an objective parameter to help clinicians decide whether to withhold FHAV administration.

Background The association between elevated serum uric acid (UA) levels and the risk of developing colonic diverticulosis has not yet been investigated. Thus, this cross-sectional study aimed to examine this correlation in individuals from Taiwan. Methods From Jan. 1, 2010, to Dec. 31, 2016., approximately 5,605 patients (aged >20 years) from Tri-Service General Hospital who met the inclusion criteria according to colonoscopy and laboratory test findings were included in this research. The correlation between serum UA levels and colonic diverticulosis was investigated via regression analyses. Results Participants with elevated serum UA levels were at a higher risk of colonic diverticulosis. The area under the curve for serum UA levels was significantly higher in women than in men (0.651 [95% confidence interval: 0.596–0.707] vs. 0.55 [0.507–0.593]). There were specific trends in female-specific indicators for colonic diverticulosis across increasing quartiles of serum UA levels. Conclusions Patients with elevated serum UA levels should be cautious regarding the development of colonic diverticulosis disorder in female. Moreover, prospective studies may provide additional information on the relationship between elevated serum UA levels and colonic diverticulosis.
