Filter by:Background: Few studies have investigated the difference of bacterial contamination between conventional reused ventilator systems and disposable closed ventilator-suction systems. The aim of this study was to investigate the bacterial contamination rates of the reused and disposable ventilation systems, and the association between system disconnection and bacterial contamination of ventilator systems. Methods: The enrolled patients used a conventional reused ventilator system and a disposable closed ventilator-suction system, respectively, for a week; specimens were then collected from the ventilators' internal system to evaluate human and environmental bacterial contamination. The sputum specimens from patients were also analyzed in this study. Results: The detection rate of bacteria in the conventional reused ventilator system was substantially higher than that in the disposable system. The inspiratory and expiratory limbs of disposable closed ventilator-suction system had higher bacterial concentrations than the conventional reused ventilator system. The bacterial concentration in the heated humidifier (HH) of the reused system was significantly higher than that in the disposable system. Positive associations existed among the bacterial concentrations at different locations in the reused and disposable ventilator systems, respectively. The predominant bacteria identified in the reused and disposable ventilator systems included Acinetobacter spp., Bacillus cereus, Elizabethkingia spp., Pseudomonas spp., and Stenotrophomonas (Xan) maltophilia. Conclusion: Both the reused and disposable ventilation systems had high bacterial contamination rates after one week of use. Disconnection of the ventilator systems should be avoided during system operation for decreasing the risks of environmental pollution and human exposure, especially for the disposable system.
This is a randomized, sham-controlled, patient masked, outcome assessor-blinded study to assess a Pharyngeal Electrical Stimulation (PES) Catheter for treatment of oropharyngeal dysphagia following a stroke.
Chronic obstructive pulmonary disease (COPD) is a common, chronic progressive lung disease that is characterized by shortness of breath, activity limitation, and a predisposition to flare-ups resulting in frequent emergency department (ED) visits and hospitalizations. COPD flare-ups increase risks of disease progression and mortality and account for the greatest proportion of preventable hospitalizations among major chronic diseases. Evidence show that timely integrated disease management can prevent future COPD flare-ups and readmissions, but recent data indicate that appropriate follow-up after a COPD hospitalization is limited. To reduce this care gap, the investigators developed a discharge care bundle to help a patient that are being discharged from hospital or ED after COPD flare-up transition to community care. The aim of this study is to assess how effective and cost-effective is such bundle delivered alone or supported by the dedicated care manager. The investigators will be assessing reduction of ED and hospital readmission.
Objective: To evaluate the effect of intrauterine navigation using intrauterine insemination catheter (IUI) one day prior to day 3 embryo transfer (ET) on pregnancy rate. Design: Pilot randomized controlled study. Setting: Tertiary referral center, King Fahad Medical City. Patients: Patients who underwent ET during the period of the study after two or less in-vitro fertilization failures and fulfilled the inclusion criteria. Interventions: Mock ETs were performed on day 2 post oocytes retrieval using intrauterine insemination catheter, followed by day 3 ET. Main Outcome Measure: Pregnancy rate. Key Words: embryo transfer, mock embryo transfer, endometrial receptivity, endometrial scratching, IVF.
This phase I trial studies the side effects of DEC-205/NY-ESO-1 fusion protein CDX-1401, poly ICLC, decitabine, and nivolumab in treating patients with myelodysplastic syndrome or acute myeloid leukemia. DEC-205/NY-ESO-1 fusion protein CDX-1401 is a vaccine that may help the immune system specifically target and kill cancer cells. Poly ICLC may help stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as nivolumab, may interfere with the ability of cancer cells to grow and spread. Giving DEC-205/NY-ESO-1 fusion protein CDX-1401, poly ICLC, decitabine, and nivolumab may work better in treating patients with myelodysplastic syndrome or acute myeloid leukemia.
Objectives: 1. To investigate the effectiveness of adjuvant with aripiprazole to methylphenidate for disruptive mood dysregulation disorder (DMDD) in youths with attention-deficit/hyperactivity disorder (ADHD) 2. To investigate the neural basis of chronic irritability in youths with functional magnetic resonance imaging (fMRI) 3. To compare the clinical characteristics of youths with comorbid ADHD and DMDD to youths with ADHD only
Emergence agitation (EA) is one of the unpleasant symptoms after general anesthesia. The patient can be irritable, uncooperate, cry, moan and combative behaviors. Sometimes the patient may need to be thrashed to prevent physical harm. The mechanism of EA is still unknown. EA is usually self limiting within 45 to 60 minutes after wake up from anesthesia. The incidence of EA is much higher in pediatric group when compared with adult. In some centre the incidence of EA can be up to 67 % depends on anesthesia technique, race, and child's temperament. Kain et al, reported that the patient who had marked EA tended to have post operative maladaptive behaviors. These maladaptive behaviors such as insomnia, eating disturbance, aggressive behavior and even developmental regression can be happen until one year after anesthesia. From the previous study, reported that fast emergence was associated with a high incidence of agitation. This prospective observation study is conducted to determine that emergence time has any effect on EA or not. The authors use process electroencephalogram (entropy) to monitor emergence time which defined as the time which state entropy level over sixty to eighty. Meanwhile, we will evaluate the emergence time by the conventional method which used the time from ceasing anesthesia to the time of eye opening by normal voice stimuli. The primary outcome of this study is the correlation between emergence time (both from Process EEG and clinical presentation) and incidence of emergence agitation. Two secondary outcomes will be measured. Firstly, the correlation between emergence time and postoperative behavioral changes. Secondly, the relationship between entropy monitoring and clinical symptoms.
The purpose of this study is to determine the prevalence of macroscopic deciduosis found randomly in Cesarean sections and the secondary objective to determine the association with any obstetrical complications or adverse effects.
The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
Positioning during the process of tracheal intubation is critical, as optimal positioning can greatly facilitate successful intubation. Many complications can occur as a result of failed intubation, ranging from airway injury, lack of oxygen, with even deaths. Today, the most popular positioning of patients for intubation is in the "sniffing" position. There is however evidence to support that intubation in the bed-up-head-elevated position may be better. In today's technological age, video assisted laryngoscopy (Laryngoscopy is the process of visualizing the vocal cords prior to intubation), a new method where the anaesthetist intubates a patient via aid of an image guided view of the airway, is increasingly popular due to its reliability and superiority to normal intubation. However, it is not widely available, and may suffer from technical breakdowns. The Glidescope is one example of a video laryngoscope, and has been widely researched in the medical literature. In this study, the investigators wish to investigate whether intubation in the bed-up-head-elevated position will be as good as, if not better than Glidescope assisted tracheal intubation, in patients undergoing elective surgery and planned for general anaesthesia.
