Admissions to a low resource neonatal unit in Malawi using The NeoTree application: A digital perinatal outcome audit
Background:
Mobile-health has increasing potential to address health outcomes in under-resourced settings as smart-phone coverage increases. The NeoTree is a mobile-health application co-developed in Malawi to improve the quality of newborn care at the point of admission to neonatal units. While collecting vital demographic and clinical data this interactive platform provides clinical decision-support, and training for the end-users (health care workers (HCW)), according to evidence based national and international guidelines.
Objective:
Our aims were to examine one month of data collected using the NeoTree in an outcome audit of babies admitted to a district-level neonatal nursery in Malawi and to demonstrate proof of concept of digital audit data in this setting.
Methods:
Using a phased approach over one month (21 Nov – 19 Dec, 2016), frontline HCWs were trained and supported to use the NeoTree to admit newborns. Discharge data were collected by the research team using a discharge form within the NeoTree ‘NeoDischarge’. Descriptive analysis was conducted on the exported pseudonomysed data and presented to the newborn care department as a digital audit.
Results:
Of 191 total admissions, 134 (70%) admissions were completed using the NeoTree and 129 (67%) were exported and analysed. Of these 129, 102 (79%) were discharged alive. Overall case fatality rate was 93 per 1000 admitted babies. Prematurity with respiratory distress syndrome, Birth Asphyxia, and Neonatal sepsis contributed to 41.6%, 58.3% and 16.6% of deaths respectively. Deaths may have been under-reported due to phased implementation and some families of babies with imminent deaths self-discharging home. Detailed characterisation of the data enabled departmental discussion of modifiable factors for quality improvement, for example improved thermoregulation of infants.
Conclusions:
This digital outcome audit demonstrates that data can be captured digitally at the bedside by HCWs in under-resourced newborn facilities and these data can contribute to meaningful review of quality of care/outcomes and potential modifiable factors. Coverage may be improved during future implementation by streamlining the admission process to be solely via digital format. Our results present a new methodology for newborn audit in low-resource settings and are a proof of concept for a novel newborn data system in these settings
Alterations in functional connectivity for language in prematurely born adolescents
Recent data suggest recovery of language systems but persistent structural abnormalities in the prematurely born. We tested the hypothesis that subjects who were born prematurely develop alternative networks for processing language. Subjects who were born prematurely (n = 22; 600–1250 g birth weight), without neonatal brain injury on neonatal cranial ultrasound, and 26 term control subjects were examined with a functional magnetic resonance imaging (fMRI) semantic association task, the Wechsler Intelligence Scale for Children-III (WISC-III) and the Clinical Evaluation of Language Fundamentals (CELF). In-magnet task accuracy and response times were calculated, and fMRI data were evaluated for the effect of group on blood oxygen level dependent (BOLD) activation, the correlation between task accuracy and activation and the functional connectivity between regions activating to task. Although there were differences in verbal IQ and CELF scores between the preterm (PT) and term control groups, there were no significant differences for either accuracy or response time for the in-magnet task. Both groups activated classic semantic processing areas including the left superior and middle temporal gyri and inferior frontal gyrus, and there was no significant difference in activation patterns between groups. Clear differences between the groups were observed in the correlation between task accuracy and activation to task at P < 0.01, corrected for multiple comparisons. Left inferior frontal gyrus correlated with accuracy only for term controls and left sensory motor areas correlated with accuracy only for PT subjects. Left middle temporal gyri correlated with task accuracy for both groups. Connectivity analyses at P < 0.001 revealed the importance of a circuit between left middle temporal gyri and inferior frontal gyrus for both groups. In addition, the PT subjects evidenced greater connectivity between traditional language areas and sensory motor areas but significantly fewer correlated areas within the frontal lobes when compared to term controls. We conclude that at 12 years of age, children born prematurely and children born at term had no difference in performance on a simple lexical semantic processing task and activated similar areas. Connectivity analyses, however, suggested that PT subjects rely upon different neural pathways for lexical semantic processing when compared to term controls. Plasticity in network connections may provide the substrate for improving language skills in the prematurely born
Six-Minute Walk Test Performance in Persons With Multiple Sclerosis While Using Passive or Powered Ankle-Foot Orthoses
Objective
To determine whether a powered ankle-foot orthosis (AFO) that provides dorsiflexor and plantar flexor assistance at the ankle can improve walking endurance of persons with multiple sclerosis (MS). Design
Short-term intervention. Setting
University research laboratory. Participants
Participants (N=16) with a neurologist-confirmed diagnosis of MS and daily use of a prescribed custom unilateral passive AFO. Interventions
Three 6-minute walk tests (6MWTs), 1 per footwear condition: shoes (no AFO), prescribed passive AFO, and portable powered AFO (PPAFO). Assistive devices were worn on the impaired limb. Main Outcome Measures
Distance walked and metabolic cost of transport were recorded during each 6MWT and compared between footwear conditions. Results
Each participant completed all three 6MWTs within the experimental design. PPAFO use resulted in a shorter 6MWT distance than did a passive AFO or shoe use. No differences were observed in metabolic cost of transport between footwear conditions. Conclusions
The current embodiment of this PPAFO did not improve endurance walking performance during the 6MWT in a sample of participants with gait impairment due to MS. Further research is required to determine whether expanded training or modified design of this powered orthosis can be effective in improving endurance walking performance in persons with gait impairment due to MS

An Ivor Lewis Esophagectomy Designed to Minimize Anastomotic Complications and Optimize Conduit Function
We describe a novel esophagogastric anastomotic technique ("side-to-side: staple line-on-staple line", STS) for intrathoracic anastomoses designed to create a large diameter anastomosis while simultaneously maintaining conduit blood supply. This technique aims to minimize the incidence of anastomotic leaks and strictures, which is a frequent source of morbidity and occasional mortality after esophagectomy. We analyze the results of this STS technique on 368 patients and compared outcomes to 112 patients who underwent esophagogastric anastomoses using an end-to-end stapler (EEA) over an 8-year time interval at our institution. The STS technique involves aligning the remaining intrathoracic esophagus over the tip of the lesser curve staple line of a stomach tube, created as a replacement conduit for the esophagus. A linear stapling device cuts through and restaples the conduit staple line to the lateral wall of the esophagus in a side-to-side fashion. The open common lumen is then closed in two layers of sutures. There was a total of 12 (3.8%) anastomotic leaks in patients who underwent STS esophagogastric anastomosis. Two of eight patients (25%) had anastomotic leaks after esophagectomy for end-stage achalasia as compared to a 2.8% leak rate (10/336) after esophagectomy for other conditions. Eighteen (5.2%) patients required a median of 2 dilatations for anastomotic stricture after STS anastomosis. Supplemental jejunostomy feedings were required in only 11.1% of patients undergoing STS anastomoses following hospital discharge. In contrast, patients undergoing EEA anastomoses demonstrated anastomotic leak and stricture rates of 16.1% and 14.3% respectively (p<0.01). Time analysis of postoperative contrast studies following the STS technique typically demonstrated a straight/uniform diameter conduit with essentially complete contrast emptying into the small bowel within 3 minutes in 88.4% of patients. The incidence of esophagogastric anastomotic leaks and strictures were extremely low using this novel anastomotic technique. Additionally we believe that based on time and qualitative analyses of postoperative contrast studies, this technique appears to optimize postoperative upper gastrointestinal tract function; however, further comparative studies are needed
