Abstract
Background: Nationally, 85% of general surgery graduates pursue fellowships reducing the incoming general surgical workforce with a predicted shortage of 41,000 general surgeons by 2025. In recent studies, the lack of confidence appears to be a major factor contributing to resident decision to pursue fellowship. The aim of the study was to determine if a hybrid academic/community program contributes to early autonomy and the decision to pursue fellowship in general surgery graduates.
Methods: We evaluated the level of confidence, level of autonomy, and decision to pursue fellowship at a hybrid academic/community program that historically graduates 70% of their residents into general surgery practice through an anonymous survey. Participants responded using Likert scales along with simple polar questions.
Results: Most current residents (90%) reported, upon graduation, that they feel very confident (45%) or fairly confident (45%) performing major cases independently. Most attendings (64%) reported that during their third year of residency, they began performing the majority (more than 75%) of their major cases as surgeon junior while current residents (55%) reported they were performing the majority as a second-year resident. Fifty-five percent of residents felt that confidence played a role in the decision to pursue fellowship. Thirty-three percent of our current chief residents and only 34% of the total general surgery residents plan to pursue fellowships. Conclusions: Our study showed that our residents appear to have earlier levels of autonomy than that experienced by our practicing surgeons when they were residents. Confidence continues to play a role in the decision to pursue fellowship and overall our residents are confident in technical skills at graduation. Our unique program continues to graduate the majority of our surgical residents into successful general surgery practice.

Abstract
Abstract
A study was designed to compare the Kjel-Foss automated macro-Kjeldahl method and a block digestion- steam distillation method. The official AOAC Kjeldahl method was used as a reference procedure. Six products with a crude protein range of 10-30% were analyzed by 23 laboratories. Five laboratories analyzed the samples by the official AOAC method, 8 laboratories used the automated Kjel-Foss method, and 11 laboratories used the block digestion with steam distillation method. Standard deviations for each product and each method for both repeatability and reproducibility are given. The block digestion- steam distillation method has been adopted official first action.

Abstract
Abstract
Background
An infiltrative cardiomyopathy is a common manifestation of AL-amyloidosis, with cardiac involvement associated with a poor prognosis. Wild-type transthyretin amyloidosis (wt-TTR), is a distinct clinical entity occurring predominantly in men > 65 yrs, that has gained interest recently due to novel treatment options. Regional strain analysis has been shown to discriminate both forms of cardiac amyloidosis from other causes of concentric left ventricular hypertrophy, with a characteristic pattern of ‘apical sparing’. Due to the significant difference in both the course of the disease and treatment options between groups, a non-invasive echocardiographic method of determining subtype would be valuable.
Aim/Method: We sought to compare traditional and novel echocardiographic parameters in a cohort of AL ( n = 80) and wild type (wt-TTR) amyloid ( n = 32) patients. All amyloid patients underwent comprehensive transthoracic echocardiography, including both conventional parameters and LV longitudinal strain. Further novel parameters were computed including the ratio of global longitudinal strain (GLS) to LV ejection fraction (LVEF), as well as GLS to indexed LV mass.
Results
wt-TTR patients had significantly greater LV mass (176 ± 59g/m2vs118 ± 37g/m2, p < 0.001), and worse diastolic dysfunction as expressed as E/E’ (21.5 ± 11vs17 ± 8, p = 0.04). LVEF was significantly lower in wt-TTR patients however remained in the normal range in both groups (53 ± 6%vs57 ± 6%, p = 0.001), whilst GLS was significantly reduced compared to AL-amyloid patients (11.5 ± 3.4%vs16.2 ± 4.6%, p < 0.001). LVEF:GLS was significantly higher in wt-TTR patients (4.93 ± 1.4vs3.87 ± 1.3, p = 0.001) reflecting a more profound reduction in strain with a relatively preserved ejection fraction. Similarly, the ratio of GLS to LV mass was significantly lower in wt-TTR amyloidosis (0.078 ± 0.05vs0.155 ± 0.07, p < 0.001), reflecting a more significant reduction in strain for a given wall thickness in wt-TTR patients. GLS:LV mass was the strongest discriminator between subtypes (AUC 0.82), with a cutoff of 0.09 giving a sensitivity and specificity of 71% and 80% respectively, for detecting wt-TTR.
Conclusion
In this cohort, patients with wt-TTR had significantly greater increase in LV wall thickness and diastolic dysfunction, which may in part reflect their increased age (77vs62). However, GLS was also significantly reduced compared to AL-amyloid, even when accounting for LV ejection fraction and LV mass, suggesting these composite parameters may have value in determining the subtype of cardiac amyloidosis.

Abstract
Older people are more prone to memory distortions and errors than young people, but do not always show greater false recognition in the Deese-Roediger-McDermott (DRM) task. We report two preregistered experiments investigating whether recent findings of age-invariant false recognition extend to designs in which studied items are blocked. According to (Tun, P. A., Wingfield, A., Rosen, M. J., & Blanchard, L. (1998). Response latencies for false memories: Gist-based processes in normal aging. Psychology and Aging, 13(2), 230-241.), age effects on false recognition in the DRM task are due to a greater reliance on gist processing which is enhanced under blocked study conditions. Experiment 1 assessed false recognition in an online variant of the DRM task where words were presented visually, with incidental encoding. The results showed Bayesian evidence against greater false recognition by older adults, whether lures were semantically associated with studied lists, or perceptually related (presented in the same distinctive font as studied lists) or both. Experiment 2 used a typical DRM procedure with auditory lists and intentional encoding, closely reproducing (Tun, P. A., Wingfield, A., Rosen, M. J., & Blanchard, L. (1998). Response latencies for false memories: Gist-based processes in normal aging. Psychology and Aging, 13(2), 230-241.) Experiment 2 but omitting an initial test of recall. The results showed evidence against an age-related increase in critical lure false recognition under these conditions. Together, the data suggest that older people do not make more associative memory errors in recognition tests than young people.

Abstract
Abstract
A collaborative study was conducted to validate new enrichment methods for the TECRA Listeria Visual Immunoassay (TLVIA). These new methods incorporate a newly formulated medium, TECRA Listeria Enrichment Broth, which does not contain the highly toxic antifungal agent, cycloheximide. The new procedures will provide an alternative to the enrichment procedures described in AOAC Method 995.22. Three food types (raw ground beef, lettuce, and ice cream) were analyzed in the United States, and 2 food types (cooked turkey and cooked fish fillets) were analyzed in Australasia. Thirty collaborators participated in the study, 16 in Australasia and 14 in the United States. With the exception of one batch of ground beef, comparison of the proportion of positive test portions (p ≥ 0.05) showed no significant difference between the TLVIA and the reference method for the 5 foods at 3 inoculation levels. For the one batch of naturally contaminated raw ground beef, the TLVIA gave significantly more confirmed positive results than the reference method.

Abstract
Abstract
Background
Danon Disease (DD) is a rare X-linked autophagic vacuolar myopathy, characterized by high penetrance and severe cardiomyopathy; cognitive, skeletal muscle and vision impairment may occur as well. Due to its rarity, clinical presentation and outcomes are still uncertain.
Purpose
To describe clinical features and outcomes of DD in female and male patients
Methods
Individuals and families from United Kingdom, Australia, and United States were recruited through via advertisements on Facebook groups related to DD. Participants completed a survey about symptoms and medical history and provided their medical records to the research team.
Results
A total of 44 patients (54.5% female) with positive genetic testing for DD were included. De novo mutations occurred in one out of four patients. Cardiomyopathy occurred in 86.3% of patients (18/24 females, 20/20 males) at a mean age of 7.3 years for males and 19.4 years for females (p=0.001). Females presented with either hypertrophic cardiomyopathy (HCM, 66.7%) or dilated cardiomyopathy (DCM, 8.3%) whereas males presented with HCM 90% of the time. 34.2% of patients were diagnosed with Wolff-Parkinson-White syndrome.
Twelve patients (7 females, 5 males) underwent cardiac magnetic resonance (CMR) Out of the 9 cases, 8 (88.9%) exhibited extensive patchy late gadolinium-enhancement (LGE) in multiple segments of the left ventricle; 3 cases also had right ventricular LGE. Median cardiac mass index was 155 g/m2 (Q1-Q3: 70–237; v.n. 31–79 g/m2). Overall, 17 (38.6%) patients died or required or heart transplant (HTx). Median age at the time of death or HTx was 17 years and 42 years in males and females, respectively (p=0.025 by the log-rank test)
Cognitive impairment, mainly described as learning disabilities, was diagnosed in 90.0% of males (18/20) and 79.2% (19/24) of females; intelligence quotient (IQ) measurement was reported in 8 patients (3 females, 5 males) and 7 of them showed IQ below the average. Symptomatic skeletal myopathy was present in 28 (63.3%) of patients, with a higher prevalence in males (85% vs. 45.8%; p<0.01). Retinopathy was reported in 14 (31.2%) patients and occurred equally in both genders (p=0.34).
Conclusions
DD causes significant cardiac morbidity with the need for transplant at a young age; in 25% of cases DD is due to a de novo mutation. While in males DD is more frequently multisystemic with a more rapid clinical deterioration, in females the clinical presentation is variable. However, the presence of severe cases in females warrant the clinicians to screen for DD in both sexes with clinical manifestations or positive family history

Abstract
Abstract
Background
Genotype-phenotype correlations in dilated cardiomyopathy (DCM) and in particular the effects of gene variants on clinical outcomes remain poorly understood.
Purpose
To investigate the prognostic role of genetic variant carrier status in a large cohort of DCM patients.
Methods
We analyzed 487 DCM patients by next-generation sequencing and categorized the disease genes into functional gene groups. The following composite outcome measures were assessed: 1) all-cause mortality, heart transplantation or left ventricular assist device (D/HTx/VAD); 2) sudden cardiac death or malignant ventricular arrhythmias (SCD/MVAs); 3) heart failure related death, heart transplantation or left ventricular assist device implantation (DHF/HTx/VAD).
Results
A total of 187 pathogenic/likely pathogenic variants were found in 180 patients (37%): 55 (11%) TTN; 19 (4%) LMNA; 24 (5%) structural cytoskeleton-Z disk genes; 16 (3%) desmosomal genes; 47 (10%) sarcomeric genes; 8 (2%) ion channels genes; 11 (2%) other genes. The occurrence of D/HTx/VAD was no different between variant carriers and non-carriers (p=0.17). However, carriers of desmosomal and LMNA variants experienced the highest rate of SCD/MVA, which was independent of the left ventricular ejection fraction.
Conclusions
Desmosomal and LMNA gene variants identify the subset of DCM patients at greatest risk for SCD and life-threatening ventricular arrhythmias, regardless the left ventricular ejection fraction.

Abstract
Increased concentrations of atmospheric greenhouse gases have led to a global mean surface temperature 1.0°C higher than during the pre-industrial period. We expand on the recent IPCC Special Report on global warming of 1.5°C and review the additional risks associated with higher levels of warming, each having major implications for multiple geographies, climates, and ecosystems. Limiting warming to 1.5°C rather than 2.0°C would be required to maintain substantial proportions of ecosystems and would have clear benefits for human health and economies. These conclusions are relevant for people everywhere, particularly in low- and middle-income countries, where the escalation of climate-related risks may prevent the achievement of the United Nations Sustainable Development Goals.

Abstract
Introduction Electronic medical record (EMR) databases have become increasingly popular for secondary purposes, such as health research. The Canadian Primary Care Sentinel Surveillance Network (CPCSSN) is the first and only pan-Canadian primary care EMR data repository, with de-identified health information for almost two million Canadians. Comprehensive and freely available documentation describing the data ‘lifecycle’ is important for assessing potential data quality issues and appropriate interpretation of research findings. Here, we describe the flow and transformation of CPCSSN data in the province of Alberta. Approach In Alberta, the data originate from 54 publicly-funded primary care settings, including one community pediatric clinic, with 318 providers contributing de-identified EMR data for 410,951 patients (as of December 2018). Data extraction methods have been developed for five different EMR systems, and include both backend and automated frontend extractions. The raw EMR data are transformed according to specific rules, including trimming implausible values, converting values and free text to standard terminologies or classification systems, and structuring the data into a common CPCSSN format. Following local data extraction and processing, the data are transferred to a central repository and made available for research and disease surveillance. Conclusion This paper aims to provide important contextual information to future CPCSSN data users.

Thalassemia and sickle cell disease (SCD) are among the most common inherited diseases worldwide. Red blood cell transfusion is a cornerstone of their treatment, but its indications have significantly changed over the past years. New therapies are emerging in both syndromes: among them, hematopoietic stem cell transplantation is now routinely proposed, and gene therapy has shown promising preliminary results.

Abstract
Background The Asenze study has the long-term goal of promoting better physical, cognitive and psychosocial functioning of children in a rural area in KwaZulu-Natal, 50 km from Durban with a view to planning interventions to promote growth and development for very young children. The specific objective in this paper was to provide information for the Child Health and Development project of the Valley Trust to assist with intervention planning. The broader goal was to assess developmental delays in communities ravaged by the HIV epidemic.The Asenze study was designed in two phases from 2008 and 2012. The current paper reports on 1581 4-6years old children in the baseline phase (2008-2010) in the five adjacent tribal areas in the study area. Method The participants included all the 4 - 6 year olds whose parents had consented to inclusion in the project and their caregivers. Data were derived from a brief questionnaire administered in the homes of participants, and subsequently from medical and psychological assessments of the children and their caregivers at the Asenze clinic. The association between child factors and other factors (geographic area, socioeconomic status (SES), parental level of education, the child's pre-school education) on the one hand and, the child's cognitive performance (as measured by the Grover Counter and subtests of the KABC-11) were analysed. Linear regression models were employed to determine which predictor variables of interest in a model were associated with the children's cognitive scores as the dependent variables. Results Based on the data, the principal factors associated with children's cognitive outcomes were height-for-age z-score (HAZ), preschool education and the area of residence, Generally children who had low cognitive scores were more often stunted (as defined by the WHO anthropometric tables), had not had pre-school education, and came from areas less favourable in terms of local infrastructure and access to employment opportunities and arable land. Conclusion The finding from this cross-sectional analysis of baseline data showed that in addition to height for age and pre-school education, which are commonly thought to impact on cognition, the local authority area where the children lived was associated with their scores on cognitive tests. This has implications for intervention planning. The functioning of local government in promoting the type of community development which will protect the rights of children should be taken into account.

Abstract
BACKGROUND The use of home parenteral nutrition (HPN) for palliative indications is increasing internationally and is the leading indication in some countries. Discharge on HPN can be complex in metabolically unstable patients and requires intestinal failure expertise. METHODS Between 2012 and 2018, we performed a retrospective analysis aiming to assess the impact of a novel remote discharge pathway for palliative HPN patients. This was evaluated using a quality improvement approach. RESULTS One hundred and twenty-five patients with active malignancy [mean (range) age 58 (25-80) years] were referred to the intestinal failure unit (IFU) for remote discharge. Of 82 patients were discharged from the oncology Centre on HPN using the pathway. The remaining 43 patients either declined HPN or the Oncology team felt that the patient became too unwell for HPN or died prior to discharge. There was an increase in patients referred for remote discharge from 13 in 2012 to 43 in 2017. The mean number of days between receipt of referral by the IFU to discharge on HPN from the oncology centre reduced from 29.4 days to 10.1 days. Following remote discharge, the mean number of days on HPN was 215.9 days. Catheter-related blood stream infection rates in this cohort were very low at 0.169 per 1000 catheter days. CONCLUSIONS This is the first study to demonstrate the remote safe, effective and rapid discharge of patients requiring palliative HPN between two hospital sites. This allows patients with a short prognosis more time in their desired location.

Abstract
AIMS The purpose of this exploratory study was to investigate if the 24-hour activity profile (i.e. waking activities and sleep) objectively measured using wrist-worn accelerometry of patients scheduled for total hip arthroplasty (THA) improves postoperatively. PATIENTS AND METHODS A total of 51 THA patients with a mean age of 64 years (24 to 87) were recruited from a single public hospital. All patients underwent THA using the same surgical approach with the same prosthesis type. The 24-hour activity profiles were captured using wrist-worn accelerometers preoperatively and at 2, 6, 12, and 26 weeks postoperatively. Patient-reported outcomes (Hip Disability and Osteoarthritis Outcome Score (HOOS)) were collected at all timepoints except two weeks postoperatively. Accelerometry data were used to quantify the intensity (sedentary, light, moderate, and vigorous activities) and frequency (bouts) of activity during the day and sleep efficiency. The analysis investigated changes with time and differences between Charnley class. RESULTS Patients slept or were sedentary for a mean of 19.5 hours/day preoperatively and the 24-hour activity pattern did not improve significantly postoperatively. Outside of sleep, the patients spent their time in sedentary activities for a mean of 620 minutes/day (sd 143) preoperatively and 641 minutes/day (sd 133) six months postoperatively. No significant improvements were observed for light, moderate, and vigorous intensity activities (p = 0.140, p = 0.531, and p = 0.407, respectively). Sleep efficiency was poor (< 85%) at all timepoints. There was no postoperative improvement in sleep efficiency when adjusted for medications (p > 0.05). Patient-reported outcome measures showed a significant improvement with time in all domains when compared with preoperative levels. There were no differences with Charnley class at six months postoperatively. However, Charnley class C patients were more sedentary at two weeks postoperatively when compared with Charnley class A patients (p < 0.05). There were no further differences between Charnley classifications. CONCLUSION This study describes the 24-hour activity profile of THA patients for the first time. Prior to THA, patients in this cohort were inactive and slept poorly. This cohort shows no improvement in 24-hour activity profiles at six months postoperative.
