The wide application of ISR and DST has greatly improved the anal preservation rate for low rectal cancers, but the technical difficulty has also been obviously increased because of the limited pelvic space. Although many scholars have tried to solve this problem, all the methods have failed to fundamentally solve the problem of "the oblique dissection" of the distal rectum. To solve the problem above, the director of this clinical trial has explored a new distal rectal resection method-- transanterior obturator nerve gateway approach. The purpose of this clinical trial is to prospectively collect and compare data on the patients' perioperative variables and postoperative functional and oncological outcomes of this novel approach with the traditional approach to confirm the safety and feasibility of this novel approach and its advantages over the traditional approach.
Neck pain is an important public health problem with a high lifetime prevalence and frequently occurring in all industrialized countries. Clinical practice guidelines for chronic neck pain recommend conservative management. Conservative treatment includes many approaches such as endurance, stretching and strengthening exercises, manual therapy, proprioceptive exercises, pilates and yoga. In patients with chronic neck pain, atrophy of deep neck muscles, deterioration in fiber type ratio, muscle tenderness and decreased range of motion are observed. These problems cause poor cervical postural control system and thus impaired sense of proprioception, loss of balance, decreased eye movement and cervical muscle activity. Sensorimotor control of upright posture and head-eye movement relies on information from the vestibular, visual, and proprioceptive systems that assemble throughout the central nervous system.The cervical spine has an important role in providing proprioceptive input. This role is associated with an abundance of cervical mechanoreceptors. Recent studies have shown that proprioceptive training is associated with cervical joint position sense, joint range of motion, pain and disability. Also yoga combines physical exercises with breathing techniques and meditation and yoga is one of the most commonly used complementary treatments for neck pain.The aim of study is to determine the effectiveness of exercises for sensorimotor structure and yoga exercises with physical and meditative effects in individuals with chronic neck pain.
Rationale: Obstructive sleep apnea (OSA) is a highly prevalent, often undiagnosed, modifiable risk factor for atrial fibrillation (AF), as well as AF-related complications and treatment effectiveness. It is unclear which OSA-related pathophysiological mechanism, i.e. intrathoracic pressure shifts, hypoxemia or sympathovagal imbalance, plays the most dominant role, and a better understanding of these mechanisms could provide valuable information in future diagnostic and therapeutic strategies in this population. Objective: The primary objective is to assess the role of OSA-related pathophysiological mechanisms in the initiation of AF by a multi-parametric strategy that combines the estimated parameters. The main hypothesis is that intrathoracic pressure fluctuations are the predominant mechanism. The secondary objective is to validate a nonobtrusive sensing technology based on photoplethysmography (PPG) and diaphragm electromyography (dEMG) measurements as surrogates for gold standard technology based on invasive intraoesophageal pressure (PES) measurement. Study population: Adult patients with paroxysmal AF with nocturnal onset and high risk of OSA based on the STOP-BANG questionnaire. Study design: An observational study in a selected cohort. Subjects are recruited from the AF outpatient clinic of the Catharina Hospital, and referred to Kempenhaeghe Centre for Sleep Medicine for a one-night full PSG, with the addition of dEMG and PPG. The acquired data will be analysed at the Eindhoven Technical University. Main study parameters/endpoints: Primary endpoint: Identification of prognostic factors for the initiation of AF in relation to OSA-related pathophysiological mechanisms..nl
A common therapeutic intervention after spinal cord injury (SCI) is prolonged standing in a standing frame. For people with SCI, standing for 40 minutes or more, three to four times weekly improves several health-related issues including well-being, circulation, skin integrity, reflex activity, bowel and bladder function, digestion, sleep, pain, and fatigue. However, a person who experiences orthostatic hypotension (OH)-defined as a decrease of 20mm hg in systolic blood pressure or a decrease of 10mm hg in diastolic pressure within 3 minutes of standing from a sitting or supine position-secondary to SCI may not tolerate positioning in a standing frame, thus resulting in a loss of access to these health benefits. OH is common for people with SCI. It results from central nervous system dysregulation causing pooling of blood in the lower extremities that can lead to dizziness, light-headedness, blurred vision, weakness, fatigue, nausea, palpitations, headache, and/or syncope. Although an array of physical and pharmacologic interventions are available to people in the general population for managing OH, few such interventions have been evaluated for use by people with SCI, especially when the level of injury is C5 or above. One possible intervention that may be effective for people with OH secondary to SCI is functional electrical stimulation (FES) because its application results in a dose-dependent increase in blood pressure. An unanswered question is whether the placement of FES electrodes on various parts of the body has differential effects. Therefore, the purpose of this study is to evaluate blood pressure responses among people with OH secondary to cervical SCI when receiving FES intervention involving the placement of electrodes in three different positions as well as when receiving no FES intervention during tilt table sessions. The selected positions for electrode placement are: (a) the calves, (b) the quads and abdominals, and (c) the quads, abdominals, and calves. The researchers hypothesize that FES intervention, regardless of placement, will result in better control of OH than no FES intervention and that no significant blood pressure difference will occur across the three FES placements.
The study is a randomized controlled study to determine the effect of white noise on sucking success and infant comfort in newborns in babies aged 34-37 weeks who were fed orally by a full enteral mother in the Neonatal Intensive Care Unit.
The aim of this study is to develop and evaluate a low intensity, multifaceted, digital health intervention to prevent T2DM based on: i) the use of a system comprising mobile health (mHealth) technology integrated with electronic health records to send tailored text messages (SMSs) promoting lifestyle changes in people at risk of T2DM, and, ii) the provision of online education to primary healthcare workers about prediabetes management.
The aim of this randomized study is to investigate local tumor control,survival outcomes and complications on patients of liver metastasis in small cell lung cancer.
This is a continuation study to the Omega Tots trial (NCT01576783). The purpose of this study is to follow-up with participants of the original study to determine the long-term effect a daily fatty acid dietary supplement taken during toddlerhood might have on children born preterm now that they are 8.5-10.5 years old.
The primary objective is to use machine learning methods on large survey and health register data to identify participants with different treatment trajectories and health outcomes after surgical and/or conservative treatment for spinal disorders. Secondary objectives are to 1) conduct external validation of the prediction models, and 2) explore how the prediction models can be implemented into AI-based clinical co-decision tools and interventions.
aimed to discuss the short term surgical outcomes of Anatomical versus Non anatomical laparoscopic Liver resection for Liver tumors.
