The Power of Mobile Health: The Girl With the Gadgets in Uganda.

Medical-grade ultrasound devices are now pocket sized and can be easily transported to underserved parts of the world, allowing health care providers to have the tools to optimize diagnoses, inform management plans, and improve patient outcomes in remote locations. Other great advances in technology have recently occurred, such as artificial intelligence applied to mobile health devices and cloud computing, as augmented reality instructions make these devices more user friendly and readily applicable across health care encounters. However, broader awareness of the impact of these mobile health technologies is needed among health care providers, along with training on how to use them in valid and reproducible environments, for accurate diagnosis and treatment. This article provides a summary of a Mayo International Health Program journey to Bwindi, Uganda, with a portable mobile health unit. This article shows how point-of-care ultrasonography and other technologies can benefit remote clinical diagnosis and management in underserved areas around the world.

Misplaced tracheoesophageal voice prosthesis: A case of foreign body aspiration.

Foreign body aspiration (FBA) is a rare, but potentially fatal condition frequently seen in the emergency department. Bronchoscopy plays a major role in its diagnosis and treatment. In patients with laryngectomy, the strategies for airway maintenance and foreign body retrieval are limited. We describe management of a patient with laryngectomy presenting with aspiration of a tracheoesophageal voice prosthesis (TEP). The TEP was not initially seen in chest radiography; however, computed tomography showed it within the right lower bronchus. Successful extraction of the TEP was achieved through bronchoscopy with forceps and retrieval basket. Otolaryngology placed a larger TEP and secured it with sutures. TEP migration is rare, but represents a risk for FBA. Initial imaging in the emergency department can be misleading, requiring a high degree of suspicion, as the TEP device may not be seen in standard chest radiography. Flexible bronchoscopy under moderate sedation in conjunction with forceps and retrieval basket may be appropriate for treatment of FBA in patients with laryngectomy and can be performed in the emergency department, preventing hospital admission.

Reintubation Summation Calculation: A Predictive Score for Extubation Failure in Critically Ill Patients.

OBJECTIVE: To derive and validate a multivariate risk score for the prediction of respiratory failure after extubation. PATIENTS AND METHODS: We performed a retrospective cohort study of adult patients admitted to the intensive care unit from January 1, 2006, to December 31, 2015, who received mechanical ventilation for ≥48 h. Extubation failure was defined as the need for reintubation within 72 h after extubation. Multivariate logistic regression model coefficient estimates generated the Re-Intubation Summation Calculation (RISC) score. RESULTS: The 6,161 included patients were randomly divided into 2 sets: derivation (n = 3,080) and validation (n = 3,081). Predictors of extubation failure in the derivation set included body mass index <18.5 kg/m2 [odds ratio (OR), 1.91; 95% CI, 1.12-3.26; P = 0.02], threshold of Glasgow Coma Scale of at least 10 (OR, 1.68; 95% CI, 1.31-2.16; P < 0.001), mean airway pressure at 1 min of spontaneous breathing trial <10 cmH2O (OR, 2.11; 95% CI, 1.68-2.66; P < 0.001), fluid balance ≥1,500 mL 24 h preceding extubation (OR, 2.36; 95% CI, 1.87-2.96; P < 0.001), and total mechanical ventilation days ≥5 (OR, 3.94; 95% CI 3.04-5.11; P < 0.001). The C-index for the derivation and validation sets were 0.72 (95% CI, 0.70-0.75) and 0.72 (95% CI, 0.69-0.75). Multivariate logistic regression demonstrated that an increase of 1 in RISC score increased odds of extubation failure 1.6-fold (OR, 1.58; 95% CI, 1.47-1.69; P < 0.001). CONCLUSION: RISC predicts extubation failure in mechanically ventilated patients in the intensive care unit using several clinically relevant variables available in the electronic medical record but requires a larger validation cohort before widespread clinical implementation.

A Combined Approach to Intracerebral Hemorrhage: Intravenous Mesenchymal Stem Cell Therapy with Minimally Invasive Hematoma Evacuation.

BACKGROUND: Mesenchymal stem cells (MSCs) are multipotent stromal cells currently being tested as therapy for a variety of diseases. MSC therapy and hematoma evacuation using a minimally invasive approach are being studied separately to improve clinical outcomes after stroke. We report the first case of a patient with intracerebral hemorrhage (ICH) treated with combination MSC therapy and endoscopic hematoma evacuation. CASE REPORT: A 36-year-old woman with a past medical history of essential chronic hypertension and right lung bronchial atresia presented to the emergency department with acute neurologic decline (National Institute of Health Stroke Scale [NIHSS] score, 22). Computed tomography showed a 4.4 × 3.5 × 3.5 cm right basal ganglia hemorrhage with intraventricular extension. An external ventricular drain was placed, and she was enrolled in a Phase I clinical trial investigating intravenous MSC therapy for acute ICH. Continued neurologic deterioration due to increased intracranial pressure led to minimally invasive hematoma evacuation using the Artemis Neuro Evacuation Device (Penumbra, Inc.) on hospital day 4. Follow-up scans showed decreased density and extent of hemorrhage. She was discharged on day 41 with improved neurologic function scores (NIHSS score, 2). At 3-month follow-up, she was walking on her own, but had residual left arm and hand weakness (modified Rankin Score, 2). CONCLUSIONS: This case report suggests that the combination of MSC therapy and minimally invasive hematoma evacuation may be safe and well tolerated. Further larger randomized clinical trials are required to identify whether MSC therapy in combination with minimally invasive hematoma evacuation is safe, tolerable, and potentially improves outcomes than either alone.

Focused transthoracic echocardiography curriculum for advanced practice providers assures good concordance with intensivists at echocardiography.

OBJECTIVE: To describe a focused transthoracic echocardiography (FoTE) curriculum for advanced practice providers (APPs) for echocardiography-driven diagnosis of shock in critically ill patients. METHODS: Twelve APPs in 4 intensive care units at an academic medical center received didactic sessions on FoTE, including 1-on-1 proctorship with a registered cardiac sonographer. For a period of 6 months the trainees performed individual studies, then they performed FoTE examinations on critically ill patients; their diagnoses were compared with those of experienced intensivists for the same patients. RESULTS: After 6 months of multiple steps of training, APPs could acquire good echocardiographic views, achieving a good inter-rater agreement (Cohen's κ of 0.745 [95% CI, 0.385-1.0; P < .01]) in the diagnosis of shock when compared to experienced intensivists. CONCLUSIONS: Structured FoTE curriculum enables APPs to have reasonably good diagnostic concordance with intensivists in an echocardiography-driven diagnosis of shock in critically ill patients.
