Introduction: This observational study was conducted to assess the knowledge, attitudes, and perceptions (KAP) of
Malaysians toward participating in clinical trials. It also aimed to look for factors that will influence people’s willingness to participate in trials. We planned and developed future outreach, education tools, and recruitment strategies
to increase clinical trial enrolment. Methods: A cross-sectional study was carried out on a randomly selected sample
of 398 Malaysian literate adults. An online questionnaire was created and distributed to the respondents. Descriptive
statistics were presented in the form of frequency and percentages. The chi-square test was employed to find the
association between independent variables. Results: The majority had good knowledge (61.3%) and high awareness
(88.7%) of clinical trials. However, most of them were not willing to take part in a clinical trial if they were assigned
to a group of unlicensed drugs (90.2%) or randomly assigned (66.1%). The main reasons for participating in trials
were recommendations from doctors (46.5%) and the potential for their own benefit (45.7%). Younger age was
positively associated with the necessity and confidentiality of clinical trials. Most respondents indicated negative
perceptions towards the safety of clinical trials regardless of demographic variables. Conclusion: We gained a better
understanding of Malaysian people who are potential participants in a future clinical trial. These findings could help
clinical researchers improve their understanding of the participants and develop effective outreach strategies for
clinical trial recruitment and retention.

Objective:
This study aimed to compare the accuracy of robotic spine surgery and conventional pedicle screw fixation in lumbar degenerative disease. We evaluated clinical and radiological outcomes to demonstrate the noninferiority of robotic surgery.
Methods:
This study employed propensity score matching and included 3 groups: robot-assisted mini-open posterior lumbar interbody fusion (PLIF) (robotic surgery, RS), c-arm guided minimally invasive surgery transforaminal lumbar interbody fusion (C-arm guidance, CG), and freehand open PLIF (free of guidance, FG) (54 patients each). The mean follow-up period was 2.2 years. The preoperative spine condition was considered. Accuracy was evaluated using the Gertzbein-Robbins scale (GRS score) and Babu classification (Babu score). Radiological outcomes included adjacent segmental disease (ASD) and mechanical failure. Clinical outcomes were assessed based on the visual analogue scale, Oswestry Disability Index, 36-item Short Form health survey, and clinical ASD rate.
Results:
Accuracy was higher in the RS group (p < 0.01) than in other groups. The GRS score was lower in the CG group, whereas the Babu score was lower in the FG group compared with the RS group. No significant differences were observed in radiological and clinical outcomes among the 3 groups. Regression analysis identified preoperative facet degeneration, GRS and Babu scores as significant variables for radiological and clinical ASD. Mechanical failure was influenced by the GRS score and patients’ age.
Conclusion
This study showed the superior accuracy of robotic spine surgery compared with conventional techniques. When combined with minimally invasive surgery, robotic surgery is advantageous with reduced ligament and muscle damage associated with traditional open procedures.

Background:
and Purpose Syncope is characterized by the temporary loss of consciousness and is commonly associated with migraine. However, the genetic factors that contribute to this association are not well understood. This study investigated the specific genetic loci that make patients with migraine more susceptible to syncope as well as the genetic factors contributing to syncope and migraine comorbidity in a Han Chinese population in Taiwan.
Methods:
A genome-wide association study was applied to 1,724 patients with migraine who visited a tertiary hospital in Taiwan. The patients were genotyped using the Affymetrix Axiom Genome-Wide TWB 2.0 array and categorized into the following subgroups based on migraine type: episodic migraine, chronic migraine, migraine with aura, and migraine without aura. Multivariate regression analyses were used to assess the relationships between specific single-nucleotide polymorphisms (SNPs) and the clinical characteristics in patients with syncope and migraine comorbidity.
Results:
In patients with migraine, SNPs were observed to be associated with syncope. In particular, the rs797384 SNP located in the intron region of LOC102724945 was associated with syncope in all patients with migraine. Additionally, four SNPs associated with syncope susceptibility were detected in the nonmigraine control group, and these SNPs differed from those in the migraine group, suggesting distinct underlying mechanisms. Furthermore, the rs797384 variant in the intron region of LOC102724945 was associated with the score on the Beck Depression Inventory.
Conclusions
The novel genetic loci identified in this study will improve our understanding of the genetic basis of syncope and migraine comorbidity.
