This pilot randomized controlled trial will evaluate whether catheter size affects the efficacy and performance of ultra-low-flow extracorporeal carbon dioxide removal (ECCO₂R) in mechanically ventilated adults with acute respiratory distress syndrome (ARDS) and hypercapnic respiratory acidosis. Participants will be randomly assigned to receive ECCO₂R using a 12F, 13F, or 15F catheter. The primary outcome is the percentage change in PaCO₂ from baseline during ECCO₂R. Secondary outcomes include achievement and time to correction of hypercapnic respiratory acidosis, changes in PaO₂, circuit lifespan, maximum blood flow, and device- and patient-related complications.

During critical illness, patients experience a hypercatabolic state. This hypercatabolic state causes muscle wasting in patients, resulting in intensive care unit acquired weakness (ICU-AW). ICU-AW is associated with prolonged mechanical ventilation (MV) weaning, extubating failure and extended length of stay. Previously recognized risk factors for ICU-AW include shock, sepsis, multiple organ failure, hyperglycemia, and prolonged exposure to corticosteroids, sedatives, or paralytic agents. Critical illness is complicated by the development of acute kidney injury (AKI). AKI causes muscle wasting by increasing protein degradation and decreasing protein synthesis. Furthermore, patients with severe AKI often require renal replacement therapy (RRT), which contributes to additional protein loss. Studies have estimated that amino acid losses associated with RRT may range from 5 to 19 g/d, with greater losses observed in patients undergoing continuous renal replacement therapy (CRRT). AKI requiring CRRT has recently been proposed to contribute to an increased risk of ICU-AW. Therefore, critically ill patients with AKI may require increased protein intake to compensate for these metabolic alterations. However, higher protein intake, particularly during the early acute phase of critical illness, may be associated with prolonged need for RRT or delayed kidney recovery. The objective of this trial is to compare the effects of a high protein intake versus a standard protein intake on muscle mass change in critically ill patients with AKI requiring CRRT. The goal of this clinical trial is to learn if high protein intake (1.5-1.7 g/kg/d) can reduce ICU associated weakness in critically ill patients with AKI requiring CRRT. The main questions it aims to answer is: • Does High protein intake (1.5-1.7 g/kg/d) reduce the change in RF-CSA, as measured by ultrasonography at day 7 in critically ill patients with AKI requiring CRRT Researchers will compare drug high protein intake to standard protein intake to see if high protein intake effect on muscle mass by ultrasonography. Participants will: * Receive high protein group (1.5-1.7 g/kg/d) in High protein group and standard protein intake (1.0-1.2 g/kg/d) in control group for 7 days * Rectus femoris ultrasonography was performed twice on day 1 and day 7

The goal of this randomised controlled trial is to compare the cumulative fluid balance over the first 72 h following inclusion guided by mVExUS versus standard of care in critically ill patients with acute kidney injury receiving CRKT . It will also compare the proportion of CRRT-related complications-including intradialytic hypotension and arrhythmias-between patients managed with mVExUS-guided fluid management and those receiving standard care. The main questions it aims to answer are: Does fluid removal rate guided by mVExUS will reduce cumulative fluid balance over the course of the first 72 h of CRRT in ICU patients compared to standard care Participants will: Get fluid assessment by mVExUS protocol or a strandard care every 8 hours for 72 hours

So in management of Leptospirosis patients There really is no another approach to treatment. The importance of the problem was acknowledged by the researchers. As a result, this study was performed in order to The Leptospirosis Care Bundle has been used, and has been proved that its use can reduce the risk of acute renal failure.

The goal of this observational study is to learn how common headache and migraine are and to describe headache patterns among transgender adults in Thailand. The main questions it aims to answer are: * How common are headache and migraine among transgender adults in Thailand? * What headache patterns and levels of headache-related disability do participants report? * Are gender-affirming hormone therapy, gender-affirming surgery, or HIV pre-exposure prophylaxis (PrEP) use related to headache or migraine? About 500 transgender adults aged 18 years or older who currently attend or previously attended the Tangerine Clinic in Bangkok, Thailand, will take part. Participants will: * Provide consent online * Complete an online questionnaire about their general health and headache symptoms * Answer questions about gender-affirming hormone therapy, gender-affirming surgery, and PrEP use * Complete questionnaires that screen for migraine and measure how headaches affect daily activities This study will not assign any treatment or change the participants' usual medical care.

The goal of this observational study is to learn about the variability of apixaban blood levels and identify the clinical factors that influence them in Asian patients with atrial fibrillation. The main questions it aims to answer are: 1. What are the specific pharmacokinetic parameters and their variabilities for apixaban in this patient population? 2. Which clinical factors, such as kidney function or body weight, are the primary predictors of how apixaban is cleared and distributed in the body? Participants will be asked to give consent to allow researchers to use their existing electronic outpatient medical records and previously collected blood concentration data for analysis.

Obesity is a major global health problem. Bariatric surgery is the most effective treatment, leading to substantial weight loss and improvement in obesity-related comorbidities. The most commonly performed procedures are Laparoscopic Roux-en-Y gastric bypass (LRYGB) and Laparoscopic sleeve gastrectomy (LSG). LRYGB is typically selected for patients with a BMI exceeding 50 kg/m2. Recently, LSG with duodenojejunal bypass (LSG-DJB) has been introduced. To date, no randomized controlled trial has compared LRYGB and LSG-DJB in patients with super morbid obesity, particularly regarding postoperative hormonal responses. This study aims to address this gap. If LSG-DJB results in a lower incidence of post-bariatric hypoglycemia than LRYGB, it would support its clinical benefit. Evaluation of GLP-1, GIP, glucagon, and insulin responses will clarify mechanisms underlying weight loss and postprandial glycemic changes.

The goal of this clinical trial is to determine whether a low-calorie diet combined with intensive lifestyle intervention using Integrated Personalized Diabetes Management (iPDM) is more effective than standard care in achieving diabetes remission in adults with overweight and type 2 diabetes mellitus. The study will also evaluate the effects of the intervention on metabolic and clinical outcomes associated with diabetes remission. The main questions it aims to answer are: * Does a low-calorie diet combined with intensive lifestyle intervention using iPDM increase the proportion of participants who achieve diabetes remission compared with standard care? * Does the intervention improve metabolic and patient-centered outcomes, including glycemic control, body weight, body composition, Time in Range (TIR) measured by continuous glucose monitoring (CGM), quality of life, and cost-effectiveness? Researchers will compare participants receiving a low-calorie diet combined with intensive lifestyle intervention using iPDM with participants receiving standard diabetes care to determine whether the intervention is more effective in achieving diabetes remission and improving metabolic health. Participants will: * Be randomly assigned to either the intervention group or the standard care group. * Attend study visits for assessments of diabetes-related clinical and metabolic outcomes throughout the 6-month study. * If assigned to the intervention group, consume two low-calorie meal replacements per day and follow an individualized meal plan providing no more than 1,200 kcal per day during the first 3 months (intensive phase), together with a personalized exercise program, continuous glucose monitoring (CGM), and lifestyle counseling delivered via telemedicine every 2 weeks. During the following 3 months (maintenance phase), continue lifestyle modification with reinforcement sessions delivered via telemedicine every 4 weeks while following a meal plan providing no more than 1,500 kcal per day.

The goal of this clinical trial is to learn whether adding calcitriol to vitamin D2 can improve vitamin D deficiency in children with cholestasis and chronic liver disease. Cholestasis is a condition in which bile flow is reduced, which can make it difficult for the body to absorb and process vitamin D. The study will also learn about the safety of using vitamin D2 together with calcitriol. The main questions it aims to answer are: * Does vitamin D2 plus calcitriol increase blood 25-hydroxyvitamin D (25-OHD) levels more than vitamin D2 alone after 3 months of treatment? * Does vitamin D2 plus calcitriol help more children reach an adequate vitamin D level by 3 and 6 months? * What medical problems, especially high calcium or high phosphorus levels, occur during treatment? Researchers will compare children who receive vitamin D2 alone with children who receive vitamin D2 plus calcitriol to see which treatment improves vitamin D levels more effectively and safely. Participants will: * Take vitamin D2 alone or vitamin D2 plus calcitriol as assigned by randomization * Visit the clinic for study assessments at the start of the study, at 3 months, and at 6 months * Have blood tests to measure vitamin D levels, calcium, phosphorus, parathyroid hormone, liver function, and other safety markers * Have their treatment reviewed at 3 months; participants whose vitamin D level remains low may have their treatment adjusted according to the study plan * Bring back medication packages so researchers can check how regularly the study medicines were taken

Acute liver failure patients posed high mortality rate despite receiving standard therapy. The severity and mortality even higher in patients with underlying liver disease. Acute liver failure cause hyperinflammatory response in early stage and immunoparalysis in later stage. The surge of proinflammatory cytokines leads to multiorgan failure and more liver injury. Subsequent immunoparalysis may lead to lethal secondary infections. Liver support system had been used in acute and acute ontop chronic liver disease for last several decades. Double plasma molecular adsorption system (DPMAS) is one of the promising non-biological liver support system that have been extensively investigated in acute ontop chronic liver failure from hepatits B viral. DPMAS circuit consist of BS330 (bilirubin adsorber) and HA330 (Cytokines adsorber). Thus, DPMAS can also remove various cytokines. The effect of DPMAS on immune function in these patients has not been explored. Recent randomized controlled trial by Srisawat et al. demonstrated improvement of mHLA-DR in septic shock patients who received polymyxin B extracorporeal therapy compare to control arm. Since liver failure show change of immunological profile resemble to sepsis. Investigators proposed that removal of toxic liver toxins and lethal cytokines by DPMAS will improve immunological profiles in acute ontop chronic liver failure patients. Investigators plan to conduct a randomized controlled trial in acute ontop chronic liver failure patients who admitted to intensive care unit. Investigators plan to compare the immunomodulatory effects of DPMAS with standard treatments.

Understanding the changes in bite force and occlusal force distribution in ETT is clinically important, as it can directly influence tooth prognosis, guide restorative treatment planning, and impact the long-term survival of the treated tooth. Therefore, this study aims to further explore changes and possible correlation in maximum bite force (MBF), occlusal force distribution and patients' subjective perception of chewing function of endodontically treated teeth after non-surgical root canal treatment, subsequent restoration, and during long-term follow-up, along with comparing to contralateral vital teeth. Methods: Patients aged 20-60 years who underwent non-surgical root canal treatment at the Graduate Endodontic Clinic, Faculty of Dentistry, Chulalongkorn University, with the following teeth indicated for endodontic treatment. Measurements of maximum bite force (MBF) of ETT and contralateral vital teeth, relative occlusal force (ROF), and questionnaire responses, are performed at the following time points: before NS-RCT, 1 month after completion of NS-RCT (before doing restoration), 3 months after crown restoration, 1, 2 and 4 years after completion of NS-RCT. Differences in MBF and ROF over time points within subjects and differences in MBF and ROF between ETT and their contralateral vital teeth were statistically analyzed.

This research project investigates the clinical and genetic associations of Actinic Prurigo (AP) in the Thai population. As a rare chronic photodermatosis, AP has been observed to occur more frequently in individuals with certain genetic predispositions, particularly specific Human Leukocyte Antigen (HLA) types. Previous studies have suggested variations in clinical presentation and HLA allele distributions between Asian and Western populations. The primary aim is to explore the relationship between clinical manifestations of AP and genetic profiles, including HLA typing, among Thai individuals. Additionally, the study seeks to examine whether different HLA types are associated with varying responses to treatment. The study design is a cross-sectional comparative study, involving both AP patients and age-matched healthy controls. Given the rarity of the condition, patient recruitment will be conducted across four collaborating institutions: King Chulalongkorn Memorial Hospital Siriraj Hospital Institute of Dermatology
