Higher Waist Hip Ratio Genetic Risk Score Is Associated with Reduced Weight Loss in Patients with Severe Obesity Completing a Meal Replacement Programme. J Pers Med 2022; 12:jpm12111881. [PMID: 36579607 PMCID: PMC9695448 DOI: 10.3390/jpm12111881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 10/24/2022] [Accepted: 11/03/2022] [Indexed: 11/12/2022] Open
Abstract
Background: A better understanding of the influence of genetic factors on the response to lifestyle interventions in people with obesity may allow the development of more personalised, effective and efficient therapeutic strategies. We sought to determine the influence of six obesity-related genetic risk scores on the magnitude of weight lost by patients with severe obesity who completed a dietary intervention. Methods: In this single-centre prospective cohort study, participants with severe and complicated obesity who completed a 24-week, milk-based meal replacement programme were genotyped to detect the frequency of common risk alleles for obesity and type 2 diabetes-related traits. Genetic risk scores (GRS) for six of these traits were derived. Participants with a potentially deleterious monogenic gene variant were excluded from the analysis. Results: In 93 patients completing the programme who were not carrying a known obesity-related gene mutation, 35.5% had diabetes, 53.8% were female, mean age was 51.4 ± 11 years, mean body mass index was 51.5 ± 8.7 and mean total weight loss percent at 24 weeks was 16 ± 6.3%. The waist-hip ratio (WHR) GRS was inversely associated with percentage total weight loss at 24 weeks (adjusted β for one standard deviation increase in WHR GRS -11.6 [-23.0, -0.3], p = 0.045), and patients in the lowest tertile of WHR GRS lost more weight. Conclusions: Patients with severe and complicated obesity with a genetic predisposition to central fat accumulation had less weight loss in a 24-week milk-based meal replacement programme, but there was no evidence for influence from the five other obesity-related genetic risk scores on the response to dietary restriction.

Abstract
Background Older adults frequently attend the Emergency Department (ED) and experience high rates of adverse outcomes following ED presentation including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. A presentation to an ED can be viewed as an opportunity to assess those at risk of adverse outcomes and initiate a care plan in those deemed as ‘high risk'. Our aim was to evaluate the feasibility of a physiotherapy led integrated care intervention for older adults discharged from the ED (ED-PLUS). Methods Older adults presenting to the ED with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED-PLUS (Trial registration: NCT04983602). ED-PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient’s own home. Feasibility (recruitment and retention rates) and acceptability of the programme were assessed quantitatively and qualitatively. Functional decline was examined post-intervention using the Barthel Index. All outcomes were assessed by a research nurse blinded to group allocation. Results 29 participants were recruited, indicating 97% of our recruitment target. 90% of participants completed the ED-PLUS intervention. All participants expressed positive feedback about the intervention. The incidence of functional decline at 6 weeks was 10% in the ED-PLUS group versus 70-89% in the usual care and CGA-only groups. Conclusion High adherence and retention rates were observed among participants and preliminary findings indicate a lower incidence of functional decline in the ED-PLUS group. Recruitment challenges existed in the context of COVID-19. Data collection is ongoing for six-month outcomes.

Abstract
Aromatic L-amino acid decarboxylase deficiency is an autosomal recessive disorder that results in a lack of neurotransmitters including serotonin, dopamine, noradrenaline and adrenaline. It is characterised by developmental delay, severe hypotonia and autonomic disturbance. In patients with this condition, catecholamine deficiency and autonomic dysfunction, resulting in haemodynamic instability under anaesthesia is a primary concern. There is increased sensitivity to exogenous catecholamines and indirect acting agents, such as ephedrine, are ineffective. Hypoglycaemia, difficult airway status and drug interactions such as with monoamine oxidase inhibitors are also of concern, and these patients are at risk of dystonic crises peri-operatively. A 6-year-old boy with aromatic L-amino acid decarboxylase deficiency presented for gastrointestinal endoscopy. Following multidisciplinary discussion, we elected to provide general anaesthesia with a propofol target-controlled infusion, which proceeded without incident. In this report, we describe the precautions taken in this case, and discuss the provision of general anaesthesia for children with rare neurometabolic disorders.

Abstract
Abstract
Background
Neuro-medical complications post-stroke are common and often serious [1]. We first described complications in our stroke cohort in 1998 and sought to assess whether the severity and the nature of neuro-medical complications may have changed over time due to changes in presentation and the processes of care [2].
Methods
Analysis of stroke service database, which captures all neuro-medical complications as part of its portal for the Irish National Audit of Stroke (INAS), was completed. The frequency of each of the 19 complications was expressed as the percentage of patients that developed each complication over a certain year and over 5 years. Historical comparison was made with dataset from 1998, which captured six complications.
Results
Data on 1,283 patients presenting over 5 years between 2015–2019 was collected. The median age of all patients was 71 years (Range 21–101). In all, 19 different post-stroke complications were recorded; 48% (n = 622) had post-stroke pain, while 23.85% (n = 306) had cognitive decline. Data on 100 patients from 1998 was compared for a number of common metrics including; 21.82% (n = 275) of patients developed an LRTI in the 2015–2019 cohort compared with 14%(n = 14) in the 1998 cohort (p = 0.09) while 16.29% (n = 209) of patients developed a swallow disorder compared to 21% (n = 21) in 1998 (p = 0.22).
Conclusion
There are high levels of neuro-medical complications in stroke patients. Twenty years has seen extensive investment in hyperacute stroke care yet post-acute care complications did not appear to reduce significantly between this time, albeit with low numbers. Direction of future funding may consider the full spectrum of stroke care.

Abstract
Abstract
Background
Emergency Departments (ED) are complex and challenging environments to provide care to older adults. There is currently a paucity of high quality methodological research investigating the effectiveness of interventions focused on transitions of care from the ED to primary care services (Hughes et al, 2019). This study aims to evaluate the impact of a collaborative model of care between primary and secondary care services for older adults discharged home following ED index visit.
Methods
This was an observational retrospective study. Participants aged ≥65 years discharged home from the ED of a University Teaching Hospital and referred to a Multidisciplinary Community Intervention Team (MDCIT) were included. Referral pathways were via the OPTIMEND team (Cassarino et al, 2021) and MDCIT, which is a rapid access re-enablement team based in the community and compromises nursing staff, an occupational therapist, physiotherapist, therapy and healthcare assistants. Descriptive statistics were used to profile the baseline characteristics of study participants and to summarise data related to process outcomes. Ethical approval was granted for this study (020/2021).
Results
In the study period, January—December 2020, 54 patients were referred to the MDCIT. The mean age of participants was 80.1 years (SD 8.2), 57% were female, and the most common Manchester Triage System presenting complaint was ‘limb problems’. The median Patient Experience Time within the ED was 7.4 hours (IQR 13.1); 55% of participants were seen in their home within 24 hours of discharge. A mean of 10 interventions were delivered by the MDCIT. A 9.1% incidence rate of 30 day unscheduled hospital readmission was recorded.
Conclusion
Integrated care programmes have been advocated to improve the continuum of care from the ED into the community. This evaluation has demonstrated the feasibility of implementing such a model of care. However, further methodologically robust research is required to advance the evidence base and should also focus on patient outcomes.

Abstract
SUMMARY Carbimazole is a commonly used antithyroid drug (ATD), which is associated with several well-established side effects. However, Carbimazole-induced rhabdomyolysis is rarely reported in the literature. We report a 27-year-old male who presented with upper limb myalgia and significantly raised creatine kinase elevation, 1-month post commencement of Carbimazole for Graves' disease. Carbimazole was ceased with subsequent clinical and biochemical improvement. Though the pathophysiology remains unclear, we hope to raise awareness regarding this rare adverse effect with a view to promote early recognition and prompt discontinuation of the offending medication caused by a commonly used medication in endocrinology. LEARNING POINTS Musculoskeletal complaints can relate to unidentified and untreated hyperthyroidism. However one must be mindful that the treatment for these disorders can too induce myopathies. ATD-induced myopathy should be considered when there is a temporal relationship between introduction of ATDs and the onset of symptoms. If ATD-induced myopathy is being considered, other causes of myopathy should still be outruled. Prompt discontinuation of potentially offending medications may provide resolution of symptoms and avoid significant consequences.

Abstract
Abstract
Introduction
The British Orthopaedic Association Standards for Trauma and Orthopaedics(BOAST) have produced guidelines advising that all patients be reviewed by an orthopaedic consultant within 72 hours of presentation. However, data from traditional fracture clinics rarely fulfil this criterion. Furthermore, data from the National Health Service(NHS) has determined that traditional fracture clinics have become unfit for purpose with low patient satisfaction rates, excessive waiting times and over 6.9 million missed appointments every year. Our aim is to test the feasibility of a virtual fracture clinic(VFC) with a view to reducing service costs and improving adherence to BOAST guidelines specified timeline for orthopaedic consultant review.
Method
A retrospective analysis of 103 patients referred to our pilot VFC from January 1st to 31st 2019 was carried out. We included shoulder dislocations, clavicle injuries, simple distal radius fractures, radial head fractures, metacarpal and metatarsal injuries, undisplaced fractures of the medial and lateral malleolus of the ankle and soft tissue injuries. The primary outcome measured time from presentation to review by an orthopaedic consultant. A cost analysis was also performed to estimate the overheads and potential savings associated with VFC introduction. Statistical analysis was done via SPSS.
Result
Following VFC establishment, time from ED presentation to review by orthopaedic consultant reduced from a mean of 229 hours to 72 hours(P=0.0001). Cost analysis demonstrated that the VFC created savings of €3170 per week, amounting to projected savings of €38,040.
Conclusion
VFC has the potential to improve clinical performance while delivering substantial financial savings.
Take-home message
Virtual fracture clinic improves patients review times bringing them in line with BOAST guidelines while providing significant reductions in overheads leading to potential savings of over 38,000 euro.

Leptomeningeal Relapse of Embryonal Rhabdomyosarcoma after 15 years. IRISH MEDICAL JOURNAL 2020; 112:1026. [PMID: 32311247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
Aim Rhabdomyosarcoma (RMS) is the most common malignant soft tissue tumour of childhood. We present the case of a late relapse of RMS to the leptomeninges after 15 years. Methods A 20 year old male presented with a 3 week history of headaches and nausea. He previously had RMS of his right ear diagnosed at age 5 years which was treated with concurrent chemoradiotherapy. An MRI Brain and Spine confirmed extensive leptomeningeal disease and CSF analysis confirmed the presence of recurrent embryonal RMS. Results He completed two cycles of cyclophosphamide and topotecan followed by 45Gy/25Fr of craniospinal radiotherapy. Conclusion Late relapses beyond five years can be seen in up to 9% of patients, however very late recurrences (>10 years) are exceedingly rare. Molecular based methods such as gene expression profiling can aid risk stratification and survivorship clinics may become increasingly useful in following patients with high risk features.

Deciphering the role of Rhodnius prolixus CYP4G genes in straight and methyl-branched hydrocarbon formation and in desiccation tolerance. INSECT MOLECULAR BIOLOGY 2020; 29:431-443.

Abstract
Insect cuticle hydrocarbons are involved primarily in waterproofing the cuticle, but also participate in chemical communication and regulate the penetration of insecticides and microorganisms. The last step in insect hydrocarbon biosynthesis is carried out by an insect-specific cytochrome P450 of the 4G subfamily (CYP4G). Two genes (CYP4G106 and CYP4G107) have been reported in the triatomines Rhodnius prolixus and Triatoma infestans. In this work, their molecular and functional characterization is carried out in R. prolixus, and their relevance to insect survival is assessed. Both genes are expressed almost exclusively in the integument and have an expression pattern dependent on the developmental stage and feeding status. CYP4G106 silencing diminished significantly the straight-chain hydrocarbon production while a significant reduction - mostly of methyl-branched chain hydrocarbons - was observed after CYP4G107 silencing. Molecular docking analyses using different aldehydes as hydrocarbon precursors predicted a better fit of straight-chain aldehydes with CYP4G106 and methyl-branched aldehydes with CYP4G107. Survival bioassays exposing the silenced insects to desiccation stress showed that CYP4G107 is determinant for the waterproofing properties of the R. prolixus cuticle. This is the first report on the in vivo specificity of two CYP4Gs to make mostly straight or methyl-branched hydrocarbons, and also on their differential contribution to insect desiccation.

Abstract
Abstract
Background
Prevalence of non-communicable diseases (NCD) are growing among working populations globally. The World Health Organization (WHO) estimates NCD are responsible for 80% of all premature deaths (Lancet, 2016). The purpose of this study is to determine baseline level of NCD and risk factors among mine workers and to identify intervention strategies based on results. The collected results will be compared with a NCD study on the general population of Mongolia.
Methods
A cross sectional design was used for this study. 684 employees were randomly recruited to the study. We utilised WHO questionnaire to collect anthropogenic measurements, health behaviours, alcohol consumption, smoking, NCD and work related information.. The study focused on four (4) key risk factors of hypertension, obesity, drinking habits and smoking habits. These factors are key contributors to NCD and decreased life expectancy.
Results
Results of the study showed prevalence's of hypertension 12.9%, obesity 64.1%, alcohol users 22.1% and smokers 38.8%. The general population prevalence's are 27.5%, 56.8%, 15.5% and 24.8% respectively. Differences between gender in the study cohort for smoking rate (men = 43.3%, women = 8.9%), alcohol consumption (men = 29.9%, women = 16.1%) and central obesity (men = 78.3%, women = 35.1%) were statistically significant (p < 0.05).
Conclusions
Prevalence of arterial hypertension for the mine worker cohort was lower than general population, however, obesity, drinking and smoking rates were higher. The study findings allow us to target intervention strategies to mitigate the risk of NCD development in the future.
Key messages
Understand the risk factors and control measures available to mitigate the risk of the development of NCD. Comparison of the mine site cohort with the general population to understand similarities and differences.

The Impact of Prior Season Vaccination on Subsequent Influenza Vaccine Effectiveness to Prevent Influenza-related Hospitalizations Over 4 Influenza Seasons in Canada.

Abstract
BACKGROUND Recent studies have demonstrated the possibility of negative associations between prior influenza vaccines and subsequent influenza vaccine effectiveness (VE), depending on season and strain. We investigated this association over 4 consecutive influenza seasons (2011-2012 through 2014-2015) in Canada. METHODS Using a matched test-negative design, laboratory-confirmed influenza cases and matched test-negative controls admitted to hospitals were enrolled. Patients were stratified into 4 groups according to influenza vaccine history (not vaccinated current and prior season [referent], vaccinated prior season only, vaccinated current season only, and vaccinated both current and prior season). Conditional logistic regression was used to estimate VE; prior vaccine impact was assessed each season for overall effect and effect stratified by age (<65 years, ≥65 years) and type/subtype (A/H1N1, A/H3N2, influenza B). RESULTS Overall, mainly nonsignificant associations were observed. Trends of nonsignificant decreased VE among patients repeatedly vaccinated in both prior and current season relative to the current season only were observed in the A/H3N2-dominant seasons of 2012-2013 and 2014-2015. Conversely, in 2011-2012, during which B viruses circulated, and in 2013-2014, when A/H1N1 circulated, being vaccinated in both seasons tended to result in a high VE in the current season against the dominant circulating subtype. CONCLUSIONS Prior vaccine impact on subsequent VE among Canadian inpatients was mainly nonsignificant. Even in circumstances where we observed a trend of negative impact, being repeatedly vaccinated was still more effective than not receiving the current season's vaccine. These findings favor continuation of annual influenza vaccination recommendations, particularly in older adults. CLINICAL TRIALS REGISTRATION NCT01517191.

Abstract
Background Disturbed sleep is associated with cognitive decline in neurodegenerative diseases such as Alzheimer’s disease (AD) and frontotemporal dementia (FTD). The progressive sequence of how neurodegeneration affects aspects of sleep architecture in conjunction with behavioural changes is not well understood. Methods We investigated changes in sleep architecture, spectral power and circadian rhythmicity in the tet-off rTg4510 mouse overexpressing human P301L tau within the same subjects over time. Doxycycline-induced transgene-suppressed rTg4510 mice, tTa carriers and wild-type mice were used as comparators. Spectral power and sleep stages were measured from within the home cage environment using EEG electrodes. In addition, locomotor activity and performance during a T-maze task were measured. Results Spectral power in the delta and theta bands showed a time-dependent decrease in rTg4510 mice compared to all other groups. After the initial changes in spectral power, wake during the dark period increased whereas NREM and number of REM sleep bouts decreased in rTg4510 compared to wild-type mice. Home cage locomotor activity in the dark phase significantly increased in rTg4510 compared to wild-type mice by 40 weeks of age. Peak-to-peak circadian rhythm amplitude and performance in the T-maze was impaired throughout the experiment independent of time. At 46 weeks, rTG4510 mice had significant degeneration in the hippocampus and cortex whereas doxycycline-treated rTG4510 mice were protected. Pathology significantly correlated with sleep and EEG outcomes, in addition to locomotor and cognitive measures. Conclusions We show that reduced EEG spectral power precedes reductions in sleep and home cage locomotor activity in a mouse model of tauopathy. The data shows increasing mutant tau changes sleep architecture, EEG properties, behaviour and cognition, which suggest tau-related effects on sleep architecture in patients with neurodegenerative diseases.

Abstract
Abstract
Introduction
Guidelines on falls prevention recommend case ascertainment based on opportunistic case ascertainment and referral in those who have fallen. In October 2009 we implemented a novel multidisciplinary, multifactorial falls, syncope and dizziness service with enhanced case-ascertainment through proactive, primary care-based screening for associated risk factors. In addition to comprehensive geriatric assessment, 25% of 4032 service participants underwent strength and balance training. The baseline outcomes have been previously reported.1 Funding was withdrawn, and the service closed on 31/01/2014. We examined the effect of service-closure on fractures presenting to secondary care with and without the service running.
Methods
An interrupted time series method was used. ICD-10 coded fracture numbers attending secondary care were determined (Hospital Episode Statistics from 01/02/2012-31/05/2017) for all North Tyneside residents ≥60 years at the time of service closure, including 25-months with, and 40-months without, service provision.
Results
There was a 0.9% (p=0.018) monthly reduction in falls over 25-months of service provision which increased during the winter months of a 9.8% (p=0.015) increase. In the month following the service closure there was an initial increase in fractures of 8.5% (p=0.231), followed by an increase in the monthly time trend of 1% (p=0.018). This resulted in a post-service monthly increase in fractures of 0.1%, an estimated extra 625 fractures over the 40-month post-service cessation period. At an average £8600 per fracture, the estimated cost may have been £5,375,000.
Conclusions
In this naturalistic experiment, following an initial drop in fractures, disinvestment in this service resulted in a rise in elders’ fractures presenting to secondary care. The closure of the service may have had a large unintended cost, averaging £1.5 million annually, versus annual running costs of £220,000. Further research is needed to control for patient-level characteristics and to establish the cost-effectiveness of the service.

Abstract
Abstract
Background
In 2009 we implemented a novel multidisciplinary, multifactorial falls, syncope and dizziness service model utilising proactive, primary care-based screening (≥60 years). Participants underwent comprehensive geriatric assessment, while 25% of the 4032 service participants had exercise training. All had additional lifestyle advice on exercise, alcohol intake, weight loss and smoking cessation. The preliminary outcomes of this approach have been previously reported, with occult atrial fibrillation, murmurs, ECG-evident ischaemic heart disease (IHD) etc reported to GPs for further action.1 Funding was withdrawn and the service closed on 31/01/2014. We examined IHD secondary care attendances with and without service provision.
Methods
Patients: North Tyneside residents ≥60 years at time of closure of the service in January 2014, who were presented acutely to secondary care with IHD using an interrupted time series method. ICD-10 coded IHD numbers were determined (Hospital Episode Statistics from 01/02/2012[date of a change in coding compared to service commencement in 2009] until 31/05/2017) including 25-months with, and 40-months without, service provision.
Results
The Table summarises the change in IHD +/- service provision; there was a significant reduction in IHD non-elective admissions during both time series’, but the reduction was significantly lower without service provision.
In addition, immediately following the service closure there was an initial increase in IHD complications of 18.4% (p=0.059) followed by an increase in the time trend of 2.7% (p=0.029), resulting in a 0.6% post-service monthly reduction in IHD complications.
Conclusions
Disinvestment in this service resulted in a slowdown in the underlying reduction of IHD diagnoses in secondary care. However, further research is needed to control for patient-level characteristics, the economic impact and to look at the effect of the service on other cardiovascular diseases.

Validation of the Seegene RV15 multiplex PCR for the detection of influenza A subtypes and influenza B lineages during national influenza surveillance in hospitalized adults. J Med Microbiol 2020; 69:256-264.

Abstract
Background. The Serious Outcomes Surveillance Network of the Canadian Immunization Research Network (CIRN SOS) has been performing active influenza surveillance since 2009 (ClinicalTrials.gov identifier: NCT01517191). Influenza A and B viruses are identified and characterized using real-time reverse-transcriptase polymerase chain reaction (RT-PCR), and multiplex testing has been performed on a subset of patients to identify other respiratory virus aetiologies. Since both methods can identify influenza A and B, a direct comparison was performed.Methods. Validated real-time RT-PCRs from the World Health Organization (WHO) to identify influenza A and B viruses, characterize influenza A viruses into the H1N1 or H3N2 subtypes and describe influenza B viruses belonging to the Yamagata or Victoria lineages. In a subset of patients, the Seeplex RV15 One-Step ACE Detection assay (RV15) kit was also used for the detection of other respiratory viruses.Results. In total, 1111 nasopharyngeal swabs were tested by RV15 and real-time RT-PCRs for influenza A and B identification and characterization. For influenza A, RV15 showed 98.0 % sensitivity, 100 % specificity and 99.7 % accuracy. The performance characteristics of RV15 were similar for influenza A subtypes H1N1 and H3N2. For influenza B, RV15 had 99.2 % sensitivity, 100 % specificity and 99.8 % accuracy, with similar assay performance being shown for both the Yamagata and Victoria lineages.Conclusions. Overall, the detection of circulating subtypes of influenza A and lineages of influenza B by RV15 was similar to detection by real-time RT-PCR. Multiplex testing with RV15 allows for a more comprehensive respiratory virus surveillance in hospitalized adults, without significantly compromising the reliability of influenza A or B virus detection.

Management of primary hyperparathyroidism in pregnancy: a case series. Endocrinol Diabetes Metab Case Rep 2019; 2019:EDM190039.

Abstract
Primary hyperparathyroidism (PHPT) is characterised by the overproduction of parathyroid hormone (PTH) due to parathyroid hyperplasia, adenoma or carcinoma and results in hypercalcaemia and a raised or inappropriately normal PTH. Symptoms of hypercalcaemia occur in 20% of patients and include fatigue, nausea, constipation, depression, renal impairment and cardiac arrythmias. In the most severe cases, uraemia, coma or cardiac arrest can result. Primary hyperparathyroidism in pregnancy is rare, with a reported incidence of 1%. Maternal and fetal/neonatal complications are estimated to occur in 67 and 80% of untreated cases respectively. Maternal complications include nephrolithiasis, pancreatitis, hyperemesis gravidarum, pre-eclampsia and hypercalcemic crises. Fetal complications include intrauterine growth restriction; preterm delivery and a three to five-fold increased risk of miscarriage. There is a direct relationship between the degree of severity of hypercalcaemia and miscarriage risk, with miscarriage being more common in those patients with a serum calcium greater than 2.85 mmol/L. Neonatal complications include hypocalcemia. Herein, we present a case series of three women who were diagnosed with primary hyperparathyroidism in pregnancy. Case 1 was diagnosed with multiple endocrine neoplasia type 1 (MEN1) in pregnancy and required a bilateral neck exploration and subtotal parathyroidectomy in the second trimester of her pregnancy due to symptomatic severe hypercalcaemia. Both case 2 and case 3 were diagnosed with primary hyperparathyroidism due to a parathyroid adenoma and required a unilateral parathyroidectomy in the second trimester. This case series highlights the work-up and the tailored management approach to patients with primary hyperparathyroidism in pregnancy. Learning points: Primary hyperparathyroidism in pregnancy is associated with a high incidence of associated maternal fetal and neonatal complications directly proportionate to degree of maternal serum calcium levels. Parathyroidectomy is the definitive treatment for primary hyperparathyroidism in pregnancy and was used in the management of all three cases in this series. It is recommended when serum calcium is persistently greater than 2.75 mmol/L and or for the management of maternal or fetal complications of hypercalcaemia. Surgical management, when necessary is ideally performed in the second trimester. Primary hyperparathyroidism is genetically determined in ~10% of cases, where the likelihood is increased in those under 40 years, where there is relevant family history and those with other related endocrinopathies. Genetic testing is a useful diagnostic adjunct and can guide treatment and management options for patients diagnosed with primary hyperparathyroidism in pregnancy, as described in case 1 in this series, who was diagnosed with MEN1 syndrome. Women of reproductive age with primary hyperparathyroidism need to be informed of the risks and complications associated with primary hyperparathyroidism in pregnancy and pregnancy should be deferred and or avoided until curative surgery has been performed and calcium levels have normalised.

SUN-132 Investigating the Accuracy of Risk Factor Calculators in Diagnosing Maturity Onset Diabetes of the Young (MODY). J Endocr Soc 2019.

Abstract
MODY is a rare form of diabetes caused by impaired insulin production attributable to autosomal dominant monogenic mutations. It is an important diagnosis as it results in a treatment change for 25% of patients, allows for the screening of 1st degree relatives and identifies patients who have MODY subtypes associated with reduced rates of micro- and macro-vascular complications. Diagnosing MODY is challenging and several MODY risk factor calculators have been proposed to guide rational genetic testing. The aim of this study was to retrospectively apply the MODY risk factor calculators to patients with diagnosed MODY who attended the diabetes service at a tertiary hospital in the West of Ireland to identify the most accurate calculator in predicting MODY in this patient cohort. MODY risk factor calculators in the literature focus on young age at diagnosis, low BMI and low HbA1c as defining features of MODY. Ellard, Bellanne-Chantelot et al. (2008) proposed age at diagnosis ≤25, BMI <30 and HbA1c ≤58.8 mmol/L as the recommended criteria for genetic testing in MODY, and this captured 6/21 (28.57%) patients with MODY in our cohort. Thanabalasingham, Pal et al. (2012) proposed age at diagnosis ≤30, BMI <30 and HbA1c ≤63.9 mmol/L, which accounted for 8/21 (38.1%) of our MODY patients. The MODY Probability Calculator proposed by Shields et al. (2012) was developed using logistic regression to determine the probability of MODY. Variables include current age, age at diagnosis, sex, treatment with insulin, time to insulin treatment, BMI, HbA1c and parental history of diabetes. The MODY Probability Calculator cannot be directly compared to the other calculators, as it does not define clinical criteria in a binary fashion but assigns a weighting to each factor. Patients have to be aged ≤35 at diagnosis for this calculator to be applied, which resulted in the exclusion of 3/22 patients in our cohort. 9/22 (40.9%) patients had a positive predictive value (PPV) of >50%, which conferred a 0.47/100 false negative rate and a 3/100 false positive rate if used as the basis for referring for genetic testing. 5/22 (22.73%) patients had a PPV of >75%, which conferred a 0.9/100 false negative rate and a 1.2/100 false positive rate, which is highly sensitive and specific. 12/22 (54.55%) patients had a PPV of >20%, which conferred a 0.14/100 false negative rate and a 16.8/100 false positive rate. This work demonstrates that the MODY Probability Calculator currently achieves the best balance of sensitivity / specificity in diagnosing patients with MODY. Nevertheless, a significant portion (10/22) of known MODY patients were not identified. Limitations include excluding patients aged >35 at diagnosis and excluding patients with a strong family history of diabetes who do not have an affected parent. These calculators are diagnostic adjuncts in the Endocrinologist’s toolbox to stratify MODY risk but do not replace clinical judgement.

SAT-232 Is There a Role for Genetic Testing in Guiding the Management of Primary Hyperparathyroidism in Pregnancy? J Endocr Soc 2019.

Abstract
Introduction Primary hyperparathyroidism (PHPT) in pregnancy is rare, with a reported incidence of <1%. It is associated with serious maternal and foetal complications, and is genetically determined in ~10% of cases. Confirming a genetic diagnosis can guide management of inherited PHPT, and enables screening for syndrome-related diseases. This case series highlights the role of genetic testing in the tailored management of patients with PHPT in pregnancy. Clinical cases Case 1 is a 20 year old female who was diagnosed with PHPT at 5 weeks gestation after presentation with nausea. She was hypercalcaemic (2.78 mmol/L at diagnosis; 2.98 mmol/L pre-parathyroidectomy), had negative neck ultrasonography and a MEN1 mutation (exon 2, c.236_237del, p.(Pro79fs)) on genetic testing in pregnancy. After initial management with oral and IV rehydration, her severe symptomatic hypercalcaemia required treatment with open neck exploration and a 3 gland parathyroidectomy in the 2nd trimester. The standard surgical approach of a 3.5 gland parathyroidectomy was avoided due to the risk of inducing hypoparathyroidism. Intra-operative PTH dropped 53.8% post 3 gland parathyroidectomy. Parathyroid hyperplasia on histology was consistent with the diagnosis of MEN1 syndrome. The patient’s symptoms resolved post-operatively and foetal investigations are normal at 28 weeks gestation. She is receiving close obstetric follow-up including 3-weekly foetal growth scans due to the increased risk of IUGR. She was counseled on her increased risk of pancreatic and pituitary tumours and her 1st degree relatives are undergoing genetic screening. Case 2 is a 40 year old female with a known diagnosis of PHPT who was awaiting parathyroidectomy prior to pregnancy. She was hypercalcaemic (2.78 mmol/L at 7 weeks; 2.99 mmol/L pre-parathyroidectomy), and had a lower left parathyroid adenoma on ultrasound and pre-pregnancy SPECT-CT. Genetic testing was not performed as she was 40 at diagnosis and had no contributory family history. After failure of conservative management, parathyroidectomy of the left superior parathyroid gland was performed in the 2nd trimester. Histology results confirmed a left inferior parathyroid adenoma, concordant with the radiological findings. Her symptoms improved post-operatively; she is receiving close obstetric follow-up. Clinical lessons Genetic testing enables the management of PHPT to be tailored appropriately. It can better inform the surgical approach; including the need for subtotal parathyroidectomy and bilateral neck exploration in those cases at risk of multiple parathyroid gland disease, as demonstrated in our case with MEN1. Finally this case series demonstrates that surgical management of PHPT should be considered for select cases in pregnancy and thus far no maternal or foetal complications have arisen in these featured cases following surgical intervention.

Comprehensive biodiversity analysis via ultra-deep patterned flow cell technology: a case study of eDNA metabarcoding seawater. Sci Rep 2019; 9:5991. [PMID: 30979963 PMCID: PMC6461652 DOI: 10.1038/s41598-019-42455-9] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Accepted: 04/01/2019] [Indexed: 11/09/2022] Open
Abstract
The characterization of biodiversity is a crucial element of ecological investigations as well as environmental assessment and monitoring activities. Increasingly, amplicon-based environmental DNA metabarcoding (alternatively, marker gene metagenomics) is used for such studies given its ability to provide biodiversity data from various groups of organisms simply from analysis of bulk environmental samples such as water, soil or sediments. The Illumina MiSeq is currently the most popular tool for carrying out this work, but we set out to determine whether typical studies were reading enough DNA to detect rare organisms (i.e., those that may be of greatest interest such as endangered or invasive species) present in the environment. We collected sea water samples along two transects in Conception Bay, Newfoundland and analyzed them on the MiSeq with a sequencing depth of 100,000 reads per sample (exceeding the 60,000 per sample that is typical of similar studies). We then analyzed these same samples on Illumina's newest high-capacity platform, the NovaSeq, at a depth of 7 million reads per sample. Not surprisingly, the NovaSeq detected many more taxa than the MiSeq thanks to its much greater sequencing depth. However, contrary to our expectations this pattern was true even in depth-for-depth comparisons. In other words, the NovaSeq can detect more DNA sequence diversity within samples than the MiSeq, even at the exact same sequencing depth. Even when samples were reanalyzed on the MiSeq with a sequencing depth of 1 million reads each, the MiSeq's ability to detect new sequences plateaued while the NovaSeq continued to detect new sequence variants. These results have important biological implications. The NovaSeq found 40% more metazoan families in this environment than the MiSeq, including some of interest such as marine mammals and bony fish so the real-world implications of these findings are significant. These results are most likely associated to the advances incorporated in the NovaSeq, especially a patterned flow cell, which prevents similar sequences that are neighbours on the flow cell (common in metabarcoding studies) from being erroneously merged into single spots by the sequencing instrument. This study sets the stage for incorporating eDNA metabarcoding in comprehensive analysis of oceanic samples in a wide range of ecological and environmental investigations.

Abstract
Background Stroke is a leading cause of death. We looked at the causes (direct and indirect) of in-hospital mortality in a modern stroke unit over a two-year period. Methods We reviewed medical charts of stroke deaths in hospital from 2014-2015 inclusive. Data on stroke type, aetiology, age, length of stay, comorbidities, and documented cause of death were recorded. All patients were included. Results 518 patients were admitted acutely to the stroke service. Overall death rate was 7.5% (n=39). Of fatal strokes 29 (74%) were ischaemic. Average age 78.6 years. Mean survival was 26.4 days (range 1-154). 19 (49%) patients had atrial fibrillation. Forty-nine percent of deaths were due to pneumonia, and 33% were due to raised intracranial pressure. Discussion Mortality rate in our stroke service has decreased from 15% in 1997, and now appears dichotomised into early Secondary Stroke Related Cerebral Events (SSRCEs) and later infections.

Abstract
AIMS HNF1A gene mutations are the most common cause of maturity-onset diabetes of the young (MODY) in the UK. Persons with HNF1A-MODY display sensitivity to sulphonylurea therapy; however, the long-term efficacy is not established. There is limited literature as to the prevalence of micro- and macrovascular complications in this unique cohort. The aim of this study was to determine the natural progression and clinical management of HNF1A-MODY diabetes in a dedicated MODY clinic. METHODS Sixty patients with HNF1A-MODY and a cohort of 60 BMI-, age-, ethnicity- and diabetes duration-matched patients with Type 1 diabetes mellitus participated in the study. All patients were phenotyped in detail. Clinical follow-up of the HNF1A-MODY cohort occurred on a bi-annual basis. RESULTS Following a genetic diagnosis of MODY, the majority of the cohort treated with sulphonylurea therapy remained insulin independent at 84-month follow-up (80%). The HbA1c in the HNF1A-MODY group treated with sulphonylurea therapy alone improved significantly over the study period [from 49 (44-63) mmol/mol, 6.6 (6.2-7.9)% to 41 (31-50) mmol/mol, 5.9 (5-6.7)%; P = 0.003]. The rate of retinopathy was significantly lower than that noted in the Type 1 diabetes mellitus group (13.6 vs. 50%; P = 0.0001).There was also a lower rate of microalbuminuria and cardiovascular disease in the HNF1A-MODY group compared with the Type 1 diabetes mellitus group. CONCLUSIONS This study demonstrates that the majority of patients with HNF1A-MODY can be maintained successfully on sulphonylurea therapy with good glycaemic control. We note a significantly lower rate of micro- and macrovascular complications than reported previously. The use of appropriate therapy at early stages of the disorder may decrease the incidence of complications.

Abstract
BACKGROUND Recently, a novel mutation in exon 24 of DNAJC13 gene (p.Asn855Ser, rs387907571) has been reported to cause autosomal dominant Parkinson's disease (PD) in a multi-incident Mennonite family. METHODS In the present study the mutation containing exon of the DNAJC13 gene has been sequenced in a Caucasian series consisting of 1938 patients with clinical PD and 838 with pathologically diagnosed Lewy body disease (LBD). RESULTS Our sequence analysis did not identify any coding variants in exon 24 of DNAJC13. Two previously described variants in intron 23 (rs200204728 and rs2369796) were observed. CONCLUSION Our results indicate that the region surrounding the DNAJC13 p.Asn855Ser substitution is highly conserved and mutations in this exon are not a common cause of PD or LBD among Caucasian populations.

Abstract
BACKGROUND Meningococcal meningitis occurs globally and the predominant serogroups vary by geographic region. Vaccines against serogroups A, B, C, Y and W-135 are available in Canada. OBJECTIVE To provide guidance to health care professionals for the prevention of invasive meningococcal disease in international travellers from Canada. METHODS This Statement was developed by the Committee to Advise on Tropical Medicine and Travel (CATMAT) to compliment the Canadian Immunization Guide. It considers the need for protection and the potential for adverse effects of vaccination. RESULTS Meningococcal vaccine recommendations vary by traveller characteristics and travel destination. Meningococcal meningitis occurs globally and the predominant serogroup varies by geographic region. Areas of particular risk are the "meningitis belt" in Sub-Saharan Africa, Saudi Arabia during the Hajj and Umrah pilgrimages and places with current epidemics or heightened disease activity. For healthy travellers see the Canadian Immunization Guide. Quadrivalent vaccine should be given to individuals at increased risk for invasive meningococcal disease due to medical conditions with booster doses every five years. Meningococcal B vaccine should be considered. CONCLUSION Vaccination is the most effective measure for preventing invasive meningococcal disease. The Government of Canada's travel health notices identify areas of new and recent meningococcal activity and are updated regularly.

Classroom conditions and CO2 concentrations and teacher health symptom reporting in 10 New York State Schools. INDOOR AIR 2015; 25:157-167. [PMID: 24920413 DOI: 10.1111/ina.12136] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2013] [Accepted: 05/24/2014] [Indexed: 06/03/2023]
Abstract
This study assessed the relationship between teacher-reported symptoms and classroom carbon dioxide (CO2 ) concentrations. Previous studies have suggested that poor indoor ventilation can result in higher levels of indoor pollutants, which may affect student and teacher health. Ten schools (9 elementary, 1 combined middle/high school) in eight New York State school districts were visited over a 4-month period in 2010. Carbon dioxide concentrations were measured in classrooms over 48-h, and teachers completed surveys assessing demographic information and self-reported symptoms experienced during the current school year. Data from 64 classrooms (ranging from 1 to 9 per school) were linked with 68 teacher surveys (for four classrooms, two surveys were returned). Overall, approximately 20% of the measured classroom CO2 concentrations were above 1000 parts per million (ppm), ranging from 352 to 1591 ppm. In multivariate analyses, the odds of reporting neuro-physiologic (i.e., headache, fatigue, difficulty concentrating) symptoms among teachers significantly increased (OR = 1.30, 95% CI = 1.02-1.64) for every 100 ppm increase in maximum classroom CO2 concentrations and were non-significantly increased in classrooms with above-median proportions of CO2 concentrations greater than 1000 ppm (OR = 2.26, 95% CI = 0.72-7.12).

Abstract
BACKGROUND Important gaps remain in our knowledge of the infectious diseases people acquire while travelling and the impact of pathogens imported by Canadian travellers. OBJECTIVE To provide a surveillance update of illness in a cohort of returned Canadian travellers and new immigrants. METHODS Data on returning Canadian travellers and new immigrants presenting to a CanTravNet site between September 2011 and September 2012 were extracted and analyzed by destination, presenting symptoms, common and emerging infectious diseases and disease severity. RESULTS During the study period, 2283 travellers and immigrants presented to a CanTravNet site, 88% (N=2004) of whom were assigned a travel-related diagnosis. Top three destinations for non-immigrant travellers were India (N=132), Mexico (N=103) and Cuba (N=89). Fifty-one cases of malaria were imported by ill returned travellers during the study period, 60% (N=30) of which were Plasmodium falciparum infections. Individuals travelling to visit friends and relatives accounted for 83% of enteric fever cases (15/18) and 41% of malaria cases (21/51). The requirement for inpatient management was over-represented among those with malaria compared to those without malaria (25% versus 2.8%; p<0.0001) and those travelling to visit friends and relatives versus those travelling for other reasons (12.1% versus 2.4%; p<0.0001). Nine new cases of HIV were diagnosed among the cohort, as well as one case of acute hepatitis B. Emerging infections among travellers included hepatitis E virus (N=6), chikungunya fever (N=4) and cutaneous leishmaniasis (N=16). Common chief complaints included gastrointestinal (N=804), dermatologic (N=440) and fever (N=287). Common specific causes of chief complaint of fever in the cohort were malaria (N=47/51 total cases), dengue fever (14/18 total cases), enteric fever (14/17 total cases) and influenza and influenza-like illness (15/21 total cases). Animal bites were the tenth most common diagnosis among tourist travellers. INTERPRETATION Our analysis of surveillance data on ill returned Canadian travellers provides a recent update to the spectrum of imported illness among travelling Canadians. Preventable travel-acquired illnesses and injuries in the cohort include malaria, enteric fever, HIV, hepatitis B, hepatitis A, influenza and animal bites. Strategies to improve uptake of preventive interventions such as malaria chemoprophylaxis, immunizations and arthropod/animal avoidance may be warranted.
