Skin Adhesive Plus Intra-cuticular Suture Versus Suture Alone for Cesarean Skin Closure

The goal of this randomized control trial is to compare two skin closure techniques after cesarean section. Both techniques are currently in wide use but no comparison between the two was reasserted yet. The two techniques are- First technique is intracuticular suture using monofilament suture, Second technique is intracuticular suture and biological adhesive material. The investigators' primary outcome is to explore the rate of skin scar complications to understand whether one technique has a lower complication rate then the other. The secondary outcomes is to check whether one technique is better then the other in terms of patients' satisfaction, convenience and scar healing and appearance. Patients at the age of 18 and above, undergoing elective cesarean section at the Hadassa medical center, can participate. participants will be randomly assigned to one of the groups- the firs or the second technique. Patients will be asked to fill out a questionnaire on POD 2 and attend a check-up appointment in-person with their surgeon 6-8 weeks post surgery. at the check-up the patient will be asked to fill out another questionnaire and undergo a scar appearance evaluation by the surgeon.

Efficacy of Integrating Next Generation Sequencing for Treatment of Surgical Site Infection After Fracture Fixation:

The study focuses on the serious problem of infections and wound-healing issues that can happen after high-energy bone fractures. These complications are common and can affect between 10% and 60% of patients, especially those with severe injuries. When a fracture is repaired with surgery and an infection develops afterward, patients often face long recovery times, more pain, and sometimes multiple surgeries. In the worst cases, the infection can lead to permanent disability or even amputation. The current standard test used in hospitals, called a culture, often misses certain bacteria, which can make treatment less effective. Because of this, the study aims to find out whether adding a newer test called Next Generation Sequencing (NGS) can help doctors identify infections more accurately and improve patient outcomes. The main goal of the study is to see whether using NGS along with standard hospital cultures reduces the number of treatment failures compared to using standard cultures alone. Treatment failure means the infection does not get better and the patient must return to the operating room. The study also wants to learn whether NGS helps doctors make better antibiotic choices and avoid unnecessary or ineffective treatments. Another goal is to understand which NGS results are most helpful when doctors decide to change a patient's antibiotics. By learning this, researchers hope to create a model that explains how NGS information influences treatment decisions. To join the study, patients must be between 18 and 84 years old and have a deep infection after a fracture was repaired with internal fixation, such as plates, screws, or rods. Patients must also meet infection criteria from either the Fracture-Related Infection (FRI) guidelines or the CDC's infection criteria. A total of 250 patients will be randomly placed into one of two groups: one group will receive treatment guided by both NGS and standard cultures, while the other group will receive treatment based only on standard cultures. Researchers will then compare how often treatment fails in each group. Treatment failure includes several possible outcomes. The most important is an unplanned return to the operating room because the infection did not improve. Other types of failure include new superficial infections that do not require surgery, bones that fail to heal properly (called nonunion), amputation, and complications caused by antibiotics. Patients will return for follow-up visits at 2 weeks, 6 weeks, 3 months, 6 months, and 12 months after joining the study so researchers can track the patient's progress and monitor for any problems. Right now, the failure rate for treating these infections using standard hospital cultures is about 30%, which is considered unacceptably high. The researchers believe that adding NGS will help lower this number because NGS can detect more types of bacteria, including ones that are hard to grow in a lab. With better information, doctors can choose antibiotics that are more likely to work the first time, which may reduce the need for additional surgeries and improve healing. This could be especially important for military service members, who often suffer high-energy injuries and face a greater risk of long-term complications if treatment fails. NGS is already available, covered by Medicare, and fast enough to be useful in real-time medical decisions. If this study shows that NGS improves treatment outcomes, hospitals could begin using it widely and quickly. The researchers hope that this approach will lead to fewer infections, better antibiotic use, faster recovery, and improved long-term function for patients.

A Clinical Prediction Model for Surgical Site Infection After Central Nervous System Tumor Surgery

1. Study Background For patients undergoing brain or spinal tumor surgery, postoperative surgical wound infection (known as "surgical site infection," SSI) is a recognized risk. Once an infection occurs, it may complicate and prolong the recovery process. Currently, doctors primarily rely on clinical experience to judge which patients are at higher risk of infection. Our research team has previously developed an intelligent prediction model (a machine learning tool) that can very accurately identify which patients are at higher risk of postoperative infection. This study aims to validate whether implementing enhanced preventive measures for high-risk patients in advance, based on the model's predictions, can effectively reduce the occurrence of infection. 2. Study Purpose The primary purpose of this study is to validate whether an individualized intervention strategy based on an intelligent prediction model can effectively reduce the incidence of surgical site infection in patients after central nervous system tumor surgery. Simultaneously, we will also evaluate the safety of this strategy, its impact on patient hospital stay length and medical costs, as well as its feasibility in practical clinical application. 3. Study Design Type: This is a prospective, single-center clinical validation study. "Prospective" means the research plan is established first, followed by patient recruitment and data collection according to the plan; "single-center" indicates the study is conducted solely at the Chinese Academy of Medical Sciences Cancer Hospital. Process: For all patients who consent to participate in this study, within 72 hours after surgery, the research system will automatically calculate their infection risk based on 8 key clinical indicators (such as blood test results, medical history, etc.). High-Risk Group (model-predicted infection probability ≥50%): Will receive a set of enhanced, individualized infection prevention measures (e.g., adjusted antibiotic regimen, enhanced nutritional support, closer monitoring). Low-Risk Group (model-predicted infection probability \<50%): Will receive the current standard, high-quality postoperative care. Duration: The study is planned to run from February 2026 to October 2029. Each participating patient will be followed for 3 months (90 days) to observe whether infection occurs. Sample Size: It is planned to recruit approximately 500 eligible patients. 4. Primary Evaluation Indicators Primary Indicator: The incidence of surgical site infection within 90 days after surgery. The diagnosis of infection will be made by experts who are unaware of the patient's group assignment, strictly following international standards. Secondary Indicators: Include the accuracy of the intelligent prediction model in practical use, patient hospital stay length, other infection-related complications, medical costs, and the adoption rate of the model's recommendations by physicians. 5. Eligibility Criteria (Inclusion Criteria Summary) You may be eligible to participate in this study if you meet the following conditions: Diagnosed with a brain or spinal tumor and scheduled for elective surgery. Aged 18 years or older. Expected survival exceeds 3 months and able to cooperate with postoperative follow-up. Voluntary participation and signing of a written informed consent form. (Note: This study has detailed exclusion criteria. Final confirmation of whether all criteria are met will be determined by your study doctor.) 6. Patients' Rights and Safety Voluntary Participation: Participation in this study is entirely voluntary. You have the right to withdraw from the study at any time, which will not affect the quality of any normal medical services you are entitled to at our hospital or your relationship with it. Informed Consent: Before the study begins, your study doctor will explain all study procedures, potential risks, and benefits in detail, and you will sign an "Informed Consent Form." Privacy Protection: All your personally identifiable information will be kept strictly confidential. Codes will replace your name and other identifiable information in research analyses and reports. Safety Assurance: This study has been reviewed and approved by the hospital's Ethics Committee.

Comparing Polyglactin vs Polypropylene Sutures for Rectus Sheath Closure

This randomized controlled trial aims to compare the outcomes of Polyglactin (Vicryl) versus Polypropylene (Prolene) sutures for rectus sheath closure in patients undergoing midline laparotomy. The study will evaluate the rates of incisional hernia, surgical site infection (SSI), wound dehiscence, chronic pain, and suture sinus formation. Participants aged 18-70 years, undergoing either elective or emergency laparotomy, will be randomly assigned to receive either Polyglactin or Polypropylene sutures. The primary outcome measure is the incidence of incisional hernia at 6 months, with secondary outcomes including SSI, wound complications, and chronic pain. The study is particularly important in the context of Pakistan, where such comparative data is limited, and aims to provide evidence-based recommendations for optimal suture material selection in general surgery.
