Overall survival of patients with head and neck squamous cell carcinoma (HNSCC) remains unsatisfactory due to often advanced clinical stage at diagnosis and high rate of recurrence and second primaries. About 75 % of patients with localized HNSCC are expected to show circulating tumor DNA (ctDNA) pre-treatment. ctDNA reflects tumor genome and disease burden and is termed 'liquid biopsy' (LB) when collected through venous bloodstream. LB has potential to assist in early diagnosis of recurrence and progression, and prediction of response to targeted therapeutic agents. Increased metabolic activity measured in positron emission tomography-computed tomography (PET-CT) is currently the most sensitive technique to detect residual cancer or progression of HNSCC after curative treatment. High metabolically active tumor volume (MTV) is associated with treatment resistance and shows independent prognostic significance. The objective is (i) to investigate whether MTV detected with PET-CT correlates to the pattern and amount of genetic alterations in ctDNA of patients with HNSCC referred to radio- (chemo)therapy (RT/CRT). Another objective is (ii) to determine sensitivity of LB compared to PET/CT in detecting residual tumor 3 months after completion of RT/CRT. Third (iii), genetic landscape in LB and fresh tumor samples will be evaluated to detect resistance genes and targets for immunotherapy and surveillance post-treatment. This prospective study includes 30 patients with stage III/IV HNSCC. Before onset and 3 months from RT/CRT, LB is obtained for next-generation DNA sequencing using a commercial platform. ctDNA and digital droplet PCR will be quantified and compared to MTV in simultaneously acquired PET-CT. The investigators hypothesize that LB could assist or replace PET/CT in response monitoring and detection of recurrence after RT/CRT.
A Randomized, Double blind, Placebo-controlled, Single-dose, Dose-escalation Study to Evaluate Pharmacokinetics, Safety, and Tolerability with Oral Administration of Ildong COL-144 tablet in Korean Healthy Volunteers
Surgery of the lumbar spine is characterized by diffuse and severe postoperative pain. In recent years, some case reports indicate that the thoracolumbar interfascial plane block (TLIPB) can reduce postoperative pain after spinal surgery, which targets the dorsal roots of the thoracolumbar nerves by depositing local anesthetic at the level of third lumbar vertebra between the multifidus and longissimus muscles. However, a new approach of the TLIPB technique by injecting local anesthetic between the longissimus and iliocostalis muscles, that is the Lateral TLIPB. According some relevant literature reports show that this technique simpler to perform and reduces the risk of neuraxial puncture. So, the purpose of this study is to investigate the efficacy and safety of the Lateral TLIPB combined with patient controlled intravenous analgesia (PCIA) is superior to PCIA in reducing postoperative pain in patients undergoing spinal surgery.
Lactase is high in the newborn intestine, allowing him to digest the high amounts of lactose present in breastmilk. From weaning, lactase is genetically programmed to decrease, reaching residual levels in the adult. This situation occurs in 75% of the world population and is known as "adult primary hypolactasia" while the remaining 25% is "lactase persistent" i.e. maintains in adulthood lactase values similar to these of newborns. In subjects with hypolactasia, the intake of milk products can produce digestive symptoms, making that the affected individuals spontaneously reduce the consumption of these products and, therefore, their intake of calcium and proteins. In addition to lactose-free milk and exogenous lactase, a strategy for the intolerant subjects to continue consuming dairy products is, for example, to consume yogurt, due to the fact that the lactase of the yogurt bacteria continues to function in the intestine of the consumer, hydrolyzing lactose and decreasing the development of digestive symptoms. Similarly, many probiotic strains, such as L. acidophilus NCFM, L. casei CRL431, B. longum 401 and B. bifidum Orla Jensen 1424, express β-galactosidases that hydrolyze lactose, preventing its fermentation and the production of gases. The acute administration of these strains improves lactose tolerance. In addition, a recent study reported that dietary supplementation of intolerant subjects for 4 weeks with L. casei Shirota and B. breve Yakult reduced digestive symptoms and breath hydrogen excretion not only at the end of the period of administration of the probiotics but also 3 months after having discontinued the use of probiotics. Based on this background, the aim of this study is to determine whether the regular consumption of an ice cream with the strain B. bifidum 900791 improves lactose intolerance in hypolactasic subjects, even after the suspension of the consumption of the product. To determine if this effect is due to the adaptation of the microbiota, the investigators will also evaluate changes in the composition of the microbiota and the generation of volatile fatty acids.
All patients with SLE that will be admitted in internal medicine department from August 2019 to January 2021 are eligible to be targeted and included in the study. The diagnosis of SLE will be according to the 1997 American college of Romatology revised criteria (Hochberg 1997). SLE patients with lupus nephritis will take kidney biopsy for standard care of management according to American college of Romatology guidelines 2012. The study will include three groups as follow: 1 - SLE patients with lupus nephritis. 2- SLE patients without lupus nephritis 3-A group of age and sex matched healthy individuals. The first group will represent the study group while the second and third groups group will be taken as control group Exclusion criteria: patients with 1- Chronic renal failure 2- Diabetes mellitus (DM) 3-Obstructive nephropathy 4- Renal artery stenosis 5- Hypertension 6- Heart failure 7- Hepatic diseases. 8- Existing intra renal A-V fistula. 9-Renal vein thrombosis Aims of the Research : 1. Assessment of the renal resistive index in patients with lupus nephritis (LN), in SLE patients without lupus nephritis and in the healthy controls. 2. Comparing the renal resistive index values in SLE patients with lupus nephritis with the SLE patients without LN and healthy controls. 3. Assessment of the correlation between renal resistive index (RRI) and histological findings in renal biopsy in patients with lupus nephritis. 4. Assessment of the correlation between renal resistive index (RRI) and renal function parameters (BUN, S Cr and eGFR). 5. Evaluation of the role of RRI as predictor of treatment outcomes in patients with lupus nephritis. The study will be enrolled in three steps: The first step:comparison of renal artery resistive index(RRI) values between study group and controls. The second step :correlation between RRI of the patients with lupus nephritis and histological findings in renal biopsy and/ or kidney function parameters (BUN ,SCr , eGFR). The third step:the patients with lupus nephritis will be followed up for six month receiving the usual treatment according to KDIGO guidelines 2012 to demonstrate the response to treatment in patient with pathological RRI compared to with normal RRI

The study's goal will be achieved through 3 specific aims: Demonstrate device capability to selectively and predictably engage distinct brain networks Delineate depression-relevant networks and demonstrate behavioral changes with network-targeted stimulation Demonstrate that chronic DBS using steered, individualized targeting is feasible and safe for reducing depressive symptoms
The therapeutic approach taken by trial SAKK 66/17 is different from those already used in clinical practice and possibly offers patients a therapeutic benefit after failure of standard chemotherapy and immunotherapy. Patients with laser ablation-accessible solid tumors are treated by thermal ablation followed immediately by an injection of IP-001. IP-001 is intended to trigger a tumor-specific systemic immune response when exposed to thermally liberated tumor antigens. There is strong preclinical and early clinical evidence that combining thermal ablation with IP-001 might be able to turn 'cold' tumors into 'hot' tumors, inducing a systemic immune response and resulting in shrinkage of the treated tumor including long-term response mediated by the patient's immunological defense system against any remaining tumor cells (residual primary and metastatic tumor cells) even those that are outside or distant from the treated area. This trial will provide information on the safety and tolerability of thermal ablation followed immediately by an intratumoral IP-001 injection (Ablation + IP-001) in patients with laser ablation-accessible solid tumors ('all comers', Part 1 - safety run in). Further information on safety and tolerability and as well preliminary antitumor activity will be evaluated in patients with soft tissue sarcoma (Part 2, Cohort1) and addition, in melanoma patients the anti-tumor activity will be defined as a primary objective (Part 2, Cohort 2). The trial treatment consists of an Ablation + IP-001 in 4-week intervals for up to six scheduled treatments. Thermal ablation will be performed according to the instruction of the medical device and IMP IP-001 will be administered in different dose levels according to the trial design. A follow up of all patients until progression of disease or until start of a subsequent treatment is part of the trial.

For decades, vitamin K antagonists are the main oral anticoagulants used for primary and secondary prevention of arterial and venous thromboembolic events. Both observational and randomized controlled trials have confirmed an outstanding outcome (the percentage of time in the therapeutic range-TTR, effectiveness and safety) in patients received anticoagulation management provided by pharmacists (AMPP) in comparing with usual physician care. However, at present, pharmacist-managed anticoagulation services are still not popular in developing countries. In addition, there are few studies evaluating the patient outcomes with the AMPP model in Vietnam. Above all, it is important to explore whether AMPP is superior to other usual models in the improvement of effectiveness and safety.
