A Study of Early Loading of Implants in the Maxillary Anterior Region With Alveolar Bone Defects...

Dental Implant

With the improvement of people's living standards, implant restoration has become an ideal method for partially and completely edentulous patients. Traditional classic implant theory suggests a 3-6 month undisturbed healing period is required before permanent loading can take place. However, this loading plan takes a long time and cannot timely meet the chewing function and aesthetic needs of patients with anterior maxillary tooth loss. Currently, with the continuous improvement of implant design and surface treatment techniques, the speed of implant-bone integration has been increasing, and early loading has gradually become a clinical option. After carefully reviewing the research conducted by domestic and international scholars on early loading of implants in the anterior maxillary region , we found that the cases included in the articles were patients with anterior maxillary tooth loss who did not require simultaneous guided bone regeneration (GBR) surgery. It is well known that patients with anterior maxillary tooth loss often have significant alveolar bone defects. In such cases, GBR techniques are commonly used to repair the bone defect. However, due to the lack of relevant studies, the clinical loading strategies for implant cases with accompanying bone defects are relatively conservative. Clinically, a delayed loading restoration strategy is usually employed, which typically requires a delay of 6 months or even longer. However, delayed loading increases the patient's edentulous time, affects the function and stability of the dental arch, and increases the patient's psychological burden. Therefore, whether an early loading strategy can be used for implant cases with alveolar bone defects in the anterior maxillary region has become a key issue in clinical practice. However, there is few research reported on the timing and effectiveness of early loading of implants in the anterior maxillary region with accompanying alveolar bone defects. This study aims to evaluate the clinical effects of early loading in patients with anterior maxillary single-wall bone defects through a prospective clinical randomized controlled trial.

Effect of MOPs During Orthodontic Movement in Periodontitis Patients

Stage IV PeriodontitisOrthodontic Tooth Movement

Micro-osteoperforations (MOPs) cause cortical bone injuries and consequently increase the expression of inflammatory mediators, allowing for increased bone and periodontal ligament remodeling associated with orthodontic movement. It remains unclear the effect of orthodontic intrusion combined with MOPs application on teeth with reduced periodontium. The general objective will be to determine the efficacy of MOPs during orthodontic tooth movement (OTM) in terms of periodontal and orthodontic outcomes in stage IV periodontitis patients, case type 2 with pathological tooth migration (PTM), characterized the presence of at least one flared tooth of the upper-anterior sextant with an intrabony defect (intrabony component <5mm)

Supramaximal High-Intensity Interval Training in People With and Without Chronic Obstructive Pulmonary...

COPDHealthy Controls

Beyond pulmonary complications, COPD presents with extrapulmonary manifestations including reduced cognitive, cardiovascular, and muscle function. While exercise training is the cornerstone in the non-pharmacological treatment of COPD, there is a need for new exercise training methods. The COPD-HIIT trial intend to investigate the effects and mechanisms of 12 weeks supramaximal high-intensity interval-training (HIIT) compared to moderate intensive continous training (MICT) in people with COPD and matched healthy controls on important clinical outcomes. The trial also intends to compare the effects of 24 months of exercise training (supramaximal HIIT or MICT) to usual care in people with COPD on brain health, cardiorespiratory fitness and muscle power; in people with COPD.

A Study to Assess the Effectiveness of BOTOX (Botulinum Toxin Type A) Injections for the Change...

Masseter Muscle Prominence

The masseter muscle is one of the muscles in the lower face used for chewing. Prominence of the masseter muscle can appear as a widened and square lower face shape, which is an aesthetic concern for individuals who prefer a narrower and more ovoid lower face shape. Treatments are available for masseter muscle prominice (MMP), but researchers are looking for new non-surgical treatments. This study will assess adverse events and effectiveness of BOTOX in adult participants with MMP. BOTOX is being investigated for the treatment of MMP. Participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is 1 in 4 chance that participants will be assigned to placebo. Around 248 adult participants with MMP will be enrolled in the study at approximately 30 sites in Europe. Participants will receive either BOTOX or Placebo administered as 6 intramuscular injections to the masseter on Day 1. Participants who are eligible for retreatment will be given BOTOX on Day 180 and will be followed for up to 6 months. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.

Study of Sodium Phenylbutyrate (ACER-001) for the Treatment of Patients With Medium Chain Acyl-CoA...

Medium-chain Acyl-CoA Dehydrogenase Deficiency

This is a medical research study to test a medication in patients 10 years of age and older with a disease called medium-chain acyl-CoA dehydrogenase deficiency (MCADD) caused by the common ACADM c.985 A>G (K304E) mutation. The medication is sodium phenylbutyrate (ACER-001), which is currently FDA approved for the treatment of Urea Cyle Disorders. Previous research suggests that sodium phenylbutyrate may also be effective in the treatment MCADD. This study will investigate the safety and efficacy (how well it works) of sodium phenylbutyrate in patients with MCADD.

Effectiveness of Rehabilitation in Adults Suffering From Persistent Concussion Symptoms

Postconcussion SyndromeMild Traumatic Brain Injury

Protocol Summary The present study was developed to better understand the effects and benefits of individualizing rehabilitative treatments based on subgroup classifications determined by a standardized clinical examination. The primary aim is to evaluate the response to individualized therapy on recovery, as measured by The Rivermead Post-concussion Symptoms Questionnaire (RPQ) and standardized clinical examination, when compared to an active control. The secondary aim is to evaluate the Pre and Post treatment state of the participants via a rapid advanced electroencephalography (EEG) when compared to the active control who will be provided the current standard form of therapy for persistent symptoms. The EEG changes will be compared to the standardized clinical examination findings as well as the RPQ. Sample Size: N= 50 Study Population Participants will be eligible for study participation if they meet the following inclusion criteria: 21-years and older; diagnosed with postconcussion syndrome; and have adequate language skills in English to read and take part in rehabilitation treatment program. Participants will be excluded should: they have an unremarkable or normal clinical examination; have a chronic infectious disease; uncontrolled hypertension; other neurological disorders (not attributed to their primary diagnosis); cancer treatment (other than basal cell carcinoma), craniotomy, or refractory subdural hematoma long-term use of psychoactive medications that would compromise their ability to comprehend and perform study activities; those with pacemakers or elevated cardiovascular risk; ongoing litigation surrounding their injury; have been diagnosed with a moderate or severe brain injury prior to enrolment; post-concussive symptoms persisting beyond 12-months. Study Design The investigators will be conducting a 12-week case-crossover randomized controlled trial. Participants will undergo 6-weeks of care in their respective streams. After 6-weeks, participants will undergo a re-examination. They will then crossover and undertake the alternative treatment for 6-weeks. At the end of 12-weeks, participants will undertake the endpoint examinations.

Clinical Study of Single Incision Laparoscopic Cholecystectomy in the Treatment of Patients With...

CholecystectomyLaparoscopic

Gallstone is a common disease in China.At present, the prevalence of gallstones in China is 15 %, and about 210 million people are sick. Acute cholecystitis is acute gallbladder inflammation, is one of the main complications of cholelithiasis or gallstones. The removal of gallbladder and gallstones in patients with acute cholecystitis in the presence of biliary pain will prevent the recurrence of gallbladder and reduce the risk of cholecystitis progression. If gallbladder perforation is not treated in time, the mortality rate is 30 %. Acute acalculous cholecystitis without treatment will be life-threatening, with a mortality rate of up to 50 %. At present, the vast majority of patients with acute cholecystitis are treated with 4-hole traditional laparoscopic cholecystectomy and open cholecystectomy. Their postoperative quality of life, pain and scar-related complications, remain major factors for patients.In recent years, with the renewal of the concept of minimally invasive surgery and the continuous advancement of instruments and technology, single-incision laparoscopic cholecystectomy has also maximized the quality of life after surgery and reduced postoperative pain and scar-related complications. At present, there are few reports on randomized controlled clinical trials of SILC in patients with acute cholecystitis, and there is a lack of large sample size studies.Due to the difficulty of SILC operation, the longer learning curve, the different equipment conditions and technical characteristics of each center, and the lack of standardized training, there is no effective consensus on the application indications and operation procedures of SILC in acute cholecystitis surgery. Based on the current status, the purpose of this study was to investigate the effect of SILC on postoperative quality of life, postoperative pain, scar assessment and postoperative complications in patients with acute cholecystitis, so as to propose a standardized single incision laparoscopic operation procedure in the treatment of acute cholecystitis.
