This is a prospective, single-arm, open-label，multi-center, phase II study, aiming to evaluate the efficacy and safety of AK104 combined with preoperative chemotherapy in patients with locally advanced ESCC.
The purpose of this study is to investigate the efficacy and safety of Lenvatinib Plus Tislelizumab for Locally Advanced Unresectable or Metastatic Hepatocellular Carcinoma With Hepatitis B Virus Infection and Biomarker Analyses.
The purpose of this study is to specifically evaluate the effectiveness of PuraGel, a RADA16 polypeptide hydrogel, in expediting post-operative healing and re-mucosalization of the nasoseptal flap harvest site during endoscopic skull base surgery and the impact on patient and sinonasal morbidity.
This study is a single-arm, multicenter clinical study to evaluate the efficacy and safety of Cadonilimab in combination with gemcitabine/cisplatin as a first-line treatment for recurrent or metastatic nasopharyngeal carcinoma.
Melanoma is a serious type of skin cancer and is the 5th most common cancer in the United Kingdom (UK). It can affect anywhere on the skin including on the head and neck. The cancer often is first noticed as an abnormal mole. Treatment is by removing the cancer with surgery. Early spread of the cancer can be found by testing nearby glands called lymph nodes. This operation is called a sentinel lymph node biopsy (SLNB). If the cancer has spread then new treatments, such as immunotherapy, can be given to help the person live for longer. The sentinel lymph nodes are usually in the armpits or groin for melanoma on the body, arms or legs. For cancers in the head and neck the sentinel lymph nodes will usually be in the neck. For several reasons SLNB in the neck is not offered in every hospital that manages patients with melanoma. The problem with this is that some patients who could benefit are not offered the new treatments that extend life because it is not known that their cancer has spread. In this study we aim to gather national data on the management of melanoma of the head and neck including variation in practice between different hospitals. We will use routinely collected anonymous data called 'Hospital Episode Statistics' to look at who is offered SLNB after melanoma of the head or neck, what treatments they have, if their melanoma comes back and how long they survive for. By doing this, we hope to identify whether SLNB should be made available to everyone diagnosed with melanoma of the head and neck.
Breast-feeding; It is the basic step of newborn, maternal and community health. Breastfeeding counseling, which is planned to encourage, initiate and continue breastfeeding in line with the recommendations of the World Health Organization, is extremely important in order to achieve the Sustainable Development Goals. Breastfeeding counseling with mixed reality technology will contribute to the literature. The research will be carried out between January 2023 and December 2024 in the hospitals in Mersin with a delivery room. The universe will consist of all pregnant women who come to the obstetrics clinics of the specified hospitals for follow-up purposes. G Power 3.1 program was used for sampling. By using the G Power 3.1 program in the sample calculation (30); According to the Cohen Guidelines (Cohen's d); effect size was 0.5, power was 0.80, and significance level was 0.05. It was calculated as 102 people, with at least 51 people in the intervention group and at least 51 people in the control group. The sample number was determined as 112 pregnant women to receive 10% (5 each) for the intervention and control groups in case the participants dropped out of the study. In the study, "Block Randomization" method, which is one of the fixed probability randomization methods, will be used in order to ensure homogeneity between the groups and to eliminate selection bias. In the intervention group; Introductory Information Form, Antenatal Breastfeeding Self-Efficacy Scale will be applied as a pre-test to pregnant women in their 3rd trimester and breastfeeding counseling based on mixed reality technology will be given. The LATCH Breastfeeding Diagnosis and Evaluation Scale and Postpartum Breastfeeding Self-Efficacy Scale will be filled in within 24 hours and on the 7th day after giving birth. The same steps will be performed for the pregnant women in the control group, and unlike the intervention group, counseling will be applied with Power Point technique instead of mixed reality technology. Statistical analyzes will be made using a package program called SPSS (IBM SPSS Statistics 24). In descriptive statistical analysis, mean, standard deviation, median, frequency, percentile, minimum and maximum values will be calculated. Descriptive, parametric and nonparametric statistical analysis methods will be used in the analysis of the data. Various studies have been conducted in Turkey using different methods on breastfeeding counseling, but no study has been found in which breastfeeding counseling was provided with mixed reality technology. Therefore, a randomized controlled experimental type study will be conducted to evaluate the effect of mixed reality technology-based breastfeeding counseling on breastfeeding success and self-efficacy of women.
To evaluate the efficacy and safety of envafolimab combined with concurrent chemoradiotherapy in limited stage small cell lung cancer.
Lumbosacral spine surgeries are commonly performed under GA. Perioperative pain following spine surgeries not only contributes to significant morbidities but also hampers early mobilization. Perioperative opioids, though relieve pain but hampers consciousness, increase PONV and delays mobilization. Caudal analgesia can be effectively given preemptively to alleviate pain and facilitate early mobilization. Caudal epidural block places the needle through the sacral hiatus into the epidural space to deliver medications. It can be performed as ultrasound guided procedure with very high successful rates. Single shot caudal block with local anesthetic provides analgesia for 2-4 hours but this can be further prolonged by adding adjuvants like opioids, steroids, ketamine, alpha 2 agonists, adrenaline etc. Ropivacaine is a long-acting amide local anesthetic agent which is less lipophilic, less cardiac and central nervous system toxicity with similar duration of analgesia, has lesser motor blockade and facilitates earlier mobilization than bupivacaine. Dexamethasone is a highly potent, long acting glucocorticoid. Caudal dexamethasone prolongs the analgesic duration of the ropivacaine. The aim of this study is to evaluate the role of pre-emptive caudal epidural analgesia for postoperative pain relief in lumbosacral surgeries and to compare the effect of adding dexamethasone to ropivacaine with respect to quality of analgesia, duration of analgesia, hemodynamic effects and associated side effects.
The level of pancreatic neck transection during laparoscopic pancreaticoduodenectomy (LPD) is not conclusive. Theoretically, the level of pancreatic transection can significantly affect the occurrence of postoperative pancreatic fistula (POPF) by influencing both the blood supply to the anastomosis and the location of the main pancreatic duct in the pancreatic transverse section. The investigators conduct a retropective propensity score-matched comparison to compare the impact of extended pancreatic transection and conventional pancreatic transection on POPF and the performance of the pancreaticojejunostomy during LPD.
Sexual dimorphism from skeletal remains a crucial step towards biological profile reconstruction since these are some of the last structures to remain after death. Paranasal sinuses remain intact even in extreme situations and are able to resist adverse environmental conditions due to their unique properties. The maxillary sinus is the largest of all paranasal sinuses and is considered as characteristic entity like human fingerprints for each person. Also, sphenoid air sinus is located deeply in the skull and is enveloped by different structures inside the sphenoid body. It is the least possibly affected by external deteriorating factors. Owing to limited research on the Egyptian population on the role of 3D volumetric assessment of paranasal sinuses in forensics, this study will be designed to investigate the significance of the volume of both sphenoid and maxillary sinuses in sexual discrimination.
