Tube weaning

BACKGROUND: Prolonged tracheal tube placement following severe traumatic brain injury (TBI) can cause serious complications. Safe removal requires sufficient ability for independent breathing and airway protection. Thus, identifying important factors for time to removal of the tracheal tube (decannulation) is essential for safe and efficient weaning. This study aimed to identify significant factors for time to decannulation in a Danish population of subjects with tracheostomy after TBI...

High sugar-sweetened beverage intake has been related to kidney disease and metabolic alterations in humans. We determine the impact of high sucrose intake from pregnancy until early postnatal days, and during postweaning on kidneys from adult male offspring rats. Wistar female rats were mated and assigned into two groups: one control drinking tap water (CM) and another drinking 5% sucrose diluted in water (SM). At weaning, two offspring per mother were randomly allocated into two experimental groups, one of them had free access to simple water (CO) and the other to 5% sucrose (SO) for 14 weeks...

Regulation of nucleotide biosynthesis is necessary for maintaining cellular processes including DNA replication and repair. A key enzyme in this process is deoxythymidylate kinase (dTYMK), which catalyzes the initial step in the production of dTTP from dTMP. This gene constitutes the first merged step of dTTP synthesis from the de novo and salvage pathways which regulate dTMP biosynthesis. Decreased de novo dTMP biosynthesis causes dysregulated dTTP:dUTP pools, and leads to increased uracil in DNA and neural tube closure defect (NTD) development in mice...

Introduction  The criteria for the removal of the tracheostomy tube (decannulation) vary from center to center. Some perform an endoscopic evaluation under anesthesia or computed tomography, which adds to the cost and discomfort. We use a simple two-part protocol to determine the eligibility and carry out the decannulation: part I consists of airway and swallowing assessment through an office-based flexible laryngotracheoscopy, and part II involves a tracheostomy capping trial. Objective  The primary objective was to determine the safety and efficacy of the simplified decannulation protocol followed at our center among the patients who were weaned off the mechanical ventilator and exhibited good swallowing function clinically...

Congenital nasal pyriform aperture stenosis (CNPAS) is a very rare cause of neonatal respiratory distress and is often missed because of its rarity. It arises from the overgrowth of the nasal process of the maxilla. Maxillofacial CT scan findings of pyriform aperture width <11 mm in a full-term baby, median central incisor, triangular-shaped palate, and median palatal ridge confirm the diagnosis. We describe here a case of CNPAS admitted with respiratory distress that increased further on feeding...

UNLABELLED: Nonketotic hyperglycinemia due to deficient glycine cleavage enzyme activity causes a severe neonatal epileptic encephalopathy. Current therapies based on mitigating glycine excess have only limited impact. An animal model with postnatal phenotyping is needed to explore new therapeutic approaches. We developed a Gldc p.Ala394Val mutant model and bred it to congenic status in 2 colonies on C57Bl/6J (B6) and J129X1/SvJ (J129) backgrounds. Mutant mice had reduced P-protein and enzyme activity indicating a hypomorphic mutant...

The stimulation of mesenchymal stromal cells (MSCs) with inflammatory molecules is often employed to boost their therapeutic effect. Prolonged exposure to inflammatory molecules has been explored to improve their action since MSCs therapies seem to be improved transiently with such stimuli. However, the possibility of cyclically stimulating MSCs to recover their optimized therapeutic potential is still to be elucidated, although the efficacy of cell-based therapies may be dependent on the ability to readapt to the relapse pathological conditions...

Bromvalerylurea (BVU) is a sedative-hypnotic drug with a high risk of acute poisoning. In the present case, hemodialysis (HD) was introduced in a patient with severe BVU poisoning who later demonstrated respiratory arrest, and then HD clearances (CLHD ) were assessed in detail. A 20-year-old female was transported to the emergency department by ambulance, an estimated two to four hours after orally ingesting 144 tablets of Utto® (12,000 mg BVU) in a suicide attempt. The patient was comatose on arrival...

BACKGROUND: Since weaning failure is multifactorial, comprehensive weaning scores encompassing not only the respiratory component but also nonrespiratory aspects are quintessential for successful weaning prediction. MATERIALS AND METHODS: This was a single-center prospective observational study on 128 intensive care unit (ICU) patients undergoing spontaneous breathing trials (SBT). The extubation prediction score (ExPreS), heart rate, acidosis, consciousness, oxygenation, respiratory rate (HACOR), and weaning parameters, endotracheal tube size, arterial blood gas analysis, nutrition, secretions, neuromuscular affecting agents, obstructive airway problems and wakefulness (WEANSNOW) scores were compared for their diagnostic accuracy for successful weaning prediction...

The objective was to develop an interdisciplinary weaning protocol (IWP) for patients with tracheostomy tubes due to acquired brain injury, and to effect evaluate implementation of the IWP on decannulation rates and weaning duration. An expert panel completed a literature review in 2018 to identify essential criteria in the weaning process. Based on consensus and availability in clinical practice, criteria for guiding the weaning process were included in the protocol. Using the IWP, dysphagia is graded as either severe, moderate, or mild...

BACKGROUND: Overuse of sedation and anesthesia causes delays in gastrojejunostomy tube (GJ) exchanges, increased risk of complications, unnecessary use of resources, preventable hospital admissions, and an adverse impact on patient and family experience. Our hospital was over-utilizing sedation and anesthesia, and we aimed to decrease this use from 78% to 20% within two years. METHODS: An interdisciplinary quality improvement team comprehensively evaluated current processes for GJ tube exchanges through a retrospective chart review for baseline data with prospective time series analysis after improvement implementation...

SUMMARY: Myxoedema coma is a severe form of hypothyroidism with multiple organ dysfunction, characterised by an altered state of consciousness and hypothermia. Intravenous thyroid hormone replacement therapy is the preferred treatment for myxoedema. The mortality rate associated with this disease is high, and early detection and intervention are essential. Supraglottal myxoedema is a rare form of periglottic oedema and can be fatal. A previously healthy 66-year-old man presented with impaired consciousness, hypothermia, and nonpitting oedema...

We describe a critical case of a respiratory syncytial virus (RSV) infection in a preterm infant resulting in respiratory failure with advanced respiratory interventions and discharge from our hospital without the requirement for home oxygen therapy or tube feeding. The infant, delivered at 35 weeks gestation due to a premature rupture of the membranes with a birth weight of 2 kg, initially demonstrated a stable postnatal course. The baby required no resuscitation, with Apgar scores of 8 and 9 at one and five minutes, respectively...

X is a 22-month-old White male infant with a complex medical history, including diagnoses of FBXO11 mutation, hypotonia, restrictive lung disease and mild intermittent asthma, laryngotracheomalacia, obstructive sleep apnea (OSA), feeding difficulties with a history of aspiration, gastroesophageal reflux disease (GERD), and developmental delays. X's medical presentation has resulted in multiple prior medical admissions for respiratory failure due to acute illnesses, procedures and treatments including gastrojejunostomy (GJ) tube dependence, supraglottoplasty to reshape tissues of the upper larynx, and the use of biphasic positive airway pressure (BiPAP) at night and room air during the day when he is at baseline...

Social dominance encompasses winning dyadic contests and gaining priority access to resources and reproduction. Dominance is influenced by environmental factors, particularly during early postnatal life and adolescence. A disinhibitory medial prefrontal cortex (mPFC) microcircuit has been implicated in the expression of dominance in the "tube test" social competition paradigm in mice, but the neuroplasticity underlying dominance is not known. We previously reported that male pups raised by physically active (wheel-running, as opposed to sedentary) dams exhibit tube test dominance and increased reproductive fitness, and here we show that social isolation from weaning also increases dominance...

In patients with chronic obstructive pulmonary disease (COPD), single lung transplantation (SLT) is sometimes performed as an alternative to bilateral lung transplantation due to limited organ availability. However, the postoperative management of SLT presents challenges, including complications related to the distinct compliance of each lung. This case report presents the case of a 65-year-old male patient who underwent SLT and was in the weaning period from mechanical ventilation. High-flow oxygen therapy (HFOT) was administered, and the physiological effects were measured using electrical impedance tomography (EIT)...

BACKGROUND: Pneumothorax is a common issue in the intensive care unit and emergency department, often diagnosed using lung ultrasound. The absence of lung sliding and the presence of the lung point sign are characteristic findings for pneumothorax. We describe a case of left pneumothorax diagnosed incidentally while performing a cardiac ultrasound through a new variant of the lung point sign. CASE REPORT: A 60-year-old patient with a medical history of diabetes, stroke, and right colon cancer underwent urgent surgical treatment for intestinal sub-occlusion...

BACKGROUND: Until recently, the treatment of spinal muscular atrophy (SMA) was limited to symptomatic treatment with no cure. Three innovative drugs, nusinersen, onasemnogene abeparvovec (OA), and risdiplam have been developed to treat SMA. Although the clinical trials for these drugs have demonstrated their efficacy, there is limited information on real world treatment strategies. In this study, we present a case of a male infant with SMA type 1 who underwent OA treatment after nusinersen treatment...

We present the case of a 71-year-old woman with severe bilateral primary alveolar proteinosis admitted for bilateral whole lung lavage (WLL) with a double-lumen endotracheal tube. She had a cardiac arrest of respiratory origin during the procedure and recovered after one minute of advanced resuscitation. A second LLP was scheduled under respiratory support with veno-venous extracorporeal membrane oxygenation (VV-ECMO). During this second WLL the patient was completely VV-ECMO-dependent, and the procedure was successfully completed...

(1) Background: Because of a complicated intraoperative course and/or poor recovery of graft function, approximately 15% of lung transplant (LT) recipients require prolonged mechanical ventilation (PMV) and receive a tracheostomy. This prospective study aimed to assess the effect of High-Flow Tracheal Oxygen (HFTO) on tracheostomy tube removal in LT recipients receiving PMV postoperatively. (2) Methods: The clinical course of 14 LT recipients receiving HFTO was prospectively evaluated and compared to that of 13 comparable controls receiving conventional oxygen therapy (COT) via tracheostomy...
