Background/Aims: Chronic constipation is prevalent yet under-diagnosed across Asia, compromising quality of life and burdening healthcare systems. Cultural stigma, varied diets, and limited access to standardized diagnostic tools delay timely care. Methods: The Bali Chronic Constipation Roundtable in November 2024, brought together experts from 11 Asian countries. The group reviewed epidemiological data, analyzed multinational questionnaire on clinical practice pattern, and conducted structured discussions to identify key barriers and propose region-specific recommendations. Results: Chronic constipation prevalence varies across Asia, ranging from 1.8% in India to 16.6% in Japan, with women and the elderly disproportionately affected. Under-reporting persists owing to cultural taboos and widespread self treatment with laxatives and traditional medications. Although the Rome IV criteria remains the global standard, they may not fully reflect Asian symptom profiles, and diagnosis is limited by scarce motility laboratories. First line therapies such as dietary-fiber optimization and osmotic laxatives are widely available, but newer pharmacotherapies (prucalopride, linaclotide, lubiprostone, and elobixibat) remain costly and unevenly accessible. Biofeedback for dyssynergic defecation is underutilized due to limited availability. Experts recommend expanded regional research on to refine diagnostic criteria, coupled with enhanced physician education and public awareness. They advocate accessibility to second-line and novel therapies that incorporate culturally attuned regional guidelines, and improved access to gastrointestinal motility testing. Conclusions The Bali Chronic Constipation Roundtable highlighted Asia’s need for region specific diagnostics and management. Addressing diagnostic and treatment gaps will improve outcomes, while ongoing researcher clinician policy collaboration must standardize guidelines, advance research, and ensure equitable care across Asia.

No adverse cardiovascular events occurred during the entire treatment period in both groups. <b>Conclusionb> Huoxin pill （concentrated pill） combined with Baduanjin was more effective than western therapy in improving LVEF, 6MWT distance, exercise tolerance and cardiac function in patients with acute myocardial infarction complicated with heart failure.

Background: Hearing loss (HL) is one of the most common sensory disorders, affecting over 5-8% of the world's population. Approximately half of HL cases are attributed to genetic factors. In hereditary deafness, about 75-80% is inherited through autosomal recessive inheritance, and common pathogenic genes include GJB2 and SLC26A4. Pathogenic variants in the SLC26A4gene are the leading cause of hereditary hearing loss in humans, second only to the GJB2 gene. Variants in the SLC26A4gene cause hearing loss, which can be non-syndromic autosomal recessive deafness (DFNB4, OMIM #600791) associated with enlarged vestibular aqueduct (EVA) or Pendred syndrome (Pendred, OMIM #605646). DFNB4 is characterized by sensorineural hearing loss combined with EVA or less common cochlear malformation defect. Pendred syndrome is characterized by bilateral sensorineural hearing loss with EVA and an iodine defect that can lead to thyroid goiter. Currently, it is known that EVA is associated with variants in the SLC26A4 gene and is a penetrant feature of SLC26A4-related HL. Predominant mutations in these genes differ significantly across populations. For instance, predominant SLC26A4 mutations differ among populations, including p.T416P and c.1001G>A in Caucasians, p.H723R in Japanese and Koreans, and c.919-2A>G in Han Taiwanese and Han Chinese. On the other hand, there has been no study of hearing loss related to SLC26A4 gene variants among Mongolians, which is the basis of our research. Aim: We aimed to identify the characteristics of the SLC26A4 gene variants in Mongolian people with Enlarged vestibular aqueduct and Mondini malformation. Materials and Methods: In 2022-2024, We included 13 people with hearing loss and enlarged vestibular aqueduct, incomplete cochlea (1.5 turns of the cochlea with cystic apex- incomplete partition type II- Mondini malformation) were examined by CT scan of the temporal bone in our study. WES (Whole exome sequencing) analysis was performed in the Genetics genetic-laboratory of the National Taiwan University Hospital. Results: Genetic analysis revealed 26 confirmed pathogenic variants of bi-allelic SLC26A4 gene of 8 different types in 13 cases, and c.919-2A>G variant was dominant with 46% (12/26) in allele frequency, and c.2027T>A (p.L676Q) variant 19% (5/26), c.1318A>T(p.K440X) variant 11% (3/26), c.1229C>T (p.T410M) variant 8% (2/26) ) , c.716T>A (p.V239D), c.281C>T (p.T94I), c.1546dupC, and c.1975G>C (p.V659L) variants were each 4% (1/26)- revealed. Two male children, 11 years old (SLC26A4: c.919-2A>G) and 7 years old (SLC26A4: c.919-2A>G:, SLC26A4: c.2027T>A (p.L676Q))had history of born normal hearing and progressive hearing loss. Conclusions 1. 26 variants of bi-allelic SLC26A4 gene mutation were detected in Mongolian people with EVA and Mondini malformation, and c.919-2A>G was the most dominant allele variant, and rare variants such as c.1546dupC, c.716T>A (p.V239D) were detected. 2. Our study shows that whole-exome sequencing (WES) can identify gene mutations that are not detected by polymerase chain reaction (PCR) or NGS analysis.

Background: When the incidence of the chronic shoulder pain syndrome is increasing year by year, it is necessary to determine the effects of pain relief, recovery of joint disability, and impact on quality of life through clinical trial research when calculating the results of Turem treatment, which is one of the main methods of traditional medical treatment. Aim: To study the effects of traditional medicine chiropractic on pain relief, mobility improvement, joint function recovery, and quality of life in chronic shoulder pain syndrome. Materials and Methods: The study was conducted using a single-blind, randomized controlled clinical trial (RCT) design. In the study, 60 clients were randomly selected from people suffering from of the shoulder joint pain, and group 1 received Turem treatment together with physical therapy, and group 2 received physical therapy. The results of the study were evaluated by shoulder pain (VAS score), muscle strength, range of motion of the shoulder joint with a goniometer, and the Disability of Arms, Shoulders, and Paws Questionnaire (DASH). The research was conducted in accordance with the appropriate ethical approvals (No. 2024/3-05), (No. 2024-18) and confirmed by an informed consent form. Clinical trial research results were processed using T-test, Independent T-test, repeated ANOWA test. Results: The average age of the participants in the study was 56.13±7.13 years in the treatment group and 53.87±8.05 years in the control group, and 55% were male and 45% female. When shoulder joint pain was evaluated by VAS assessment, the values before and after treatment and after 1 month of treatment in the turem treatment group and the control group decreased statistically significantly (p=0.000). There was a statistical difference between the results of the 2 study groups. When assessing muscle strength, no statistically significant difference was observed between the results of the turem treatment and control groups. When measuring the amplitude of the shoulder joint in the subjects, the amplitude of shoulder extension, abduction, external rotation, and inward rotation increased after the treatment, and compared to the two groups, the index of the turem treatment group increased with statistical significance (p=0.000). When assessed by the Hand, Shoulder, and Hand Dysfunction Questionnaire (DASH), the score of the questionnaire decreased significantly (p=0.000) before, after, and after 1 month of treatment in the turem treatment group and the control group. Turem treatment has been shown to reduce the rate of shoulder disability and improve function in chronic shoulder pain syndrome. Conclusion: Turem treatment for chronic shoulder pain syndrome can reduce shoulder pain, increase joint range, and improve muscle strength. Also, turem treatment reduced the rate of shoulder disability and improved function. Conclusion Turem treatment for chronic shoulder pain syndrome can reduce shoulder pain, increase joint range, and improve muscle strength. Also, turem treatment reduced the rate of shoulder disability and improved function.

Objective: Chest pain, a common emergency department presentation, requires rapid evaluation. The current gold standard of care is serial troponin measurements from blood draws along with an electrocardiogram and clinical presentation. However, an optical technology-based noninvasive wearable device, the Infrasensor, which can rapidly and transcutaneously assesses cardiac troponin I (cTnI), was recently developed. We aimed to perform a pilot study to evaluate the performance of the Infrasensor in cTnI defined cohorts. Methods: This was a 10-hospital prospective observational study in healthy US subjects with a normal cTnI level and in patients with an elevated local cTnI level. Healthy subjects as determined by a negative questionnaire and bloodwork underwent 3-minute Infrasensor measurement and levels of high-sensitivity cTnI (hs-cTnI), n-terminal pro-B-type natriuretic peptide (NTproBNP), creatinine, and glycosylated hemoglobin (HbA1c) were evaluated from blood. Patients with elevated cTnI had the same Infrasensor and blood sample measurements. Using a fivefold cross-validation technique, cTnI-based binary classification models that did and did not include age were trained on 80% and validated on 20% of the dataset (n=168; elevated hs-cTnI equally partitioned into five nearly equally-sized subsets ). Results: Of 840 patients, 727 (87.5%) had normal (nonelevated) cTnI levels while the remaining 113 had elevated cTnI. Median age was 61 years (interquartile range, 52–71 years) for the elevated cohort and 48 years (interquartile range, 32–57 years) for the nonelevated. Overall, 416 (50.5%) were female, with 33 of 113 (29.2%) in the elevated cohort and 383 of 727 (52.7%) in the nonelevated cohort. Overall, the sensitivity, specificity, negative and positive predictive values of the Infrasensor for identifying elevated cTnI were 0.90, 0.70, 0.98 and 0.48, respectively, with a C-statistic of 0.90 (95% confidence interval, 0.89–0.99). Conclusion The Infrasensor accurately identifies elevated cTnI within 3 minutes of application.
