Published: November 2019

Abstract
For any industry the efficiency and performance of rotating machinery/mechanical systems is a major concern. Bearings and gears are two essential parts in a rotating machinery and any defects in these components can lead to a major breakdown of the system thus causing large economical loss for the company. An appropriate machine condition monitoring system is essential in such scenarios for identifying the health of the machines. Therefore in this paper fault diagnosis of rotating mechanical systems is performed as a feature dependent-pattern classification problem. The machine is made to run in different good as well faulty conditions and the vibration signals are collected. Then chebfunction coefficients are extracted from the vibration signals as part of the feature extraction process. Finally, the extracted features are classified using regularized least squares (RLS) for identifying the good and faulty bearing as well as gear conditions of the machine. The evaluations are performed using different kernel functions and the average accuracy reported is 98% for bearing and gear data. The various experiments performed claims that the proposed system can be used for real-time fault diagnosis in rotating mechanical systems with sufficient accuracy.

Authors: Suraj  , Ansari Mohd. Zahid 
Published: November 2019

Abstract
This paper studies the effect of diaphragm size and stylus design on flow measurement characteristics of a polymer flow sensor. The sensor is made of two piezoresistive SU8/CB nanocomposite polymer cantilevers integrated with diaphragm carrying a free standing stylus its centre. The fluid flow drag force deflects the stylus which in turn deforms the anchoring cantilevers and changes their electrical resistivity. Finite element analysis software ANSYS Multiphysics used to determine the deflection, stress and sensitivity characteristics of the flow sensor at different velocities. Results show that sensitivity of flow sensor decreases with increase in diaphragm size and square stylus has better sensitivity.

Published: November 2019

AbstractThe implementation of sustainable practices within the built environment has taken over the world of construction. In as much as man continues to build, sustainable practices will continue to be a significant necessity. Like every significant change in the world, most countries have been faced with numerous challenges when adopting sustainable construction practices and Nigeria is not an exception. This study, therefore, investigates the factors impeding the adoption of sustainable construction in Nigeria. The aim of this study was achieved by seeking the opinion of various built environment professionals within Ondo State, Nigeria. The survey research design was adopted for this study and the data collected was analyzed using descriptive statistics. Findings from the study revealed that inadequate knowledge and lack of expertise in sustainable construction practices are the greatest constraints faced in the bid to adopt sustainable construction. The study concluded that if attaining full sustainability is the goal of the Nigerian construction industry, professional bodies and relevant government agencies must organize workshops and training to educate construction professionals on their practicable roles in delivering sustainable development. Furthermore, experts in the field of sustainable construction preferably from countries which have fully adopted the concept should be invited to be part of some construction projects so as to provide on-site guidance and mentorship for local professionals.
Longitudinal Analysis Supports a Fear-Avoidance Model That Incorporates Pain Resilience Alongside Pain Catastrophizing
Authors: Slepian P Maxwell , Ankawi Brett , France Christopher R 
Published: November 2019

Abstract

Background
The fear-avoidance model of chronic pain holds that individuals who catastrophize in response to injury are at risk for pain-related fear and avoidance behavior, and ultimately prolonged pain and disability.

Purpose
Based on the hypothesis that the predictive power of the fear-avoidance model would be enhanced by consideration of positive psychological constructs, the present study examined inclusion of pain resilience and self-efficacy in the model.

Methods
Men and women (N = 343) who experienced a recent episode of back pain were recruited in a longitudinal online survey study. Over a 3-month interval, participants repeated the Pain Resilience Scale, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia, Pain Self-Efficacy Questionnaire, the McGill Pain Questionnaire, and NIH-recommended measures of pain, depressive symptoms, and physical dysfunction. Structural equation modeling assessed the combined contribution of pain resilience and pain catastrophizing to 3-month outcomes through the simultaneous combination of kinesiophobia and self-efficacy.

Results
An expanded fear-avoidance model that incorporated pain resilience and self-efficacy provided a good fit to the data, Χ2 (df = 14, N = 343) = 42.09, p = .0001, RMSEA = 0.076 (90% CI: 0.05, 0.10), CFI = 0.97, SRMR = 0.03, with higher levels of pain resilience associated with improved 3-month outcomes on measures of pain intensity, physical dysfunction, and depression symptoms.

Conclusions
This study supports the notion that the predictive power of the fear-avoidance model of pain is enhanced when individual differences in both pain-related vulnerability (e.g., catastrophizing) and pain-related protective resources (e.g., resilience) are considered.

Published: November 2019

Abstract
Increased global demand for touch screens, photovoltaics, and optoelectronics has resulted in an increase in the production of indium–tin oxide (ITO). Occupational exposure to indium compounds is associated with the development of indium lung disease. Although many previous epidemiologic investigations highlight an excess of lung abnormalities in workplaces where ITO is produced, few assessments of occupational exposure to respirable and inhalable indium are reported to date. The objective of this study was to identify the determinants of respirable and inhalable indium at an ITO production facility to target exposure interventions. In 2012 and 2014, we conducted exposure assessments at an ITO production facility and collected full-shift personal respirable (n = 159) and inhalable (n = 57) indium samples. We also observed workers and recorded information on task duration and location, materials used, and use of personal protective equipment (PPE). Tasks (n = 121) recorded in task diaries were categorized into 40 similar task groups using the Advanced REACH Tool and process-related information. Mixed-effects models were fit separately for log-transformed respirable and inhalable indium, with random effect of subject and fixed effects of task groups. Overall, respirable and inhalable indium measurements ranged from 0.1 to 796.6 µg m−3 and 1.6 to 10 585.7 µg m−3, respectively, and were highly correlated with Spearman correlation coefficient of 0.90. The final model for respirable indium explained 36.3% of total variance and identified sanding, powder transfer tasks in reclaim, powder transfer tasks in refinery, handling indium materials, and liquid transfer tasks in ITO production as tasks associated with increased respirable indium exposure. The final model for inhalable indium explained 24.6% of total variance and included powder transfer tasks in ITO production, cleaning cylinder or tile, and handling indium material tasks. Tasks identified as strong predictors of full-shift exposure to respirable and inhalable indium can guide the use of engineering, administrative, and PPE controls designed to mitigate occupational exposure to indium. Moreover, since the tasks were aligned with REACH activities, results from this study can also be used to inform REACH activity scenarios.
Review of Guidelines for Dental Antibiotic Prophylaxis for Prevention of Endocarditis and Prosthetic Joint Infections and Need for Dental Stewardship
Authors: Goff Debra A , Mangino Julie E , Glassman Andrew H , Goff Douglas , Larsen Peter , Scheetz Richard 
Published: November 2019

Abstract
Dentists prescribe 10% of all outpatient antibiotic prescriptions, writing more than 25.7 million prescriptions per year. Many are for prophylaxis in patients with prosthetic joint replacements; the American Dental Society states that “in general,” prophylactic antibiotics are not recommended to prevent prosthetic joint infections. Orthopedic surgeons are concerned with the risk of implant infections following a dental procedure and, therefore, see high value and low risk in recommending prophylaxis. Patients are “stuck in the middle,” with conflicting recommendations from orthopedic surgeons (OS) and dentists. Unnecessary prophylaxis and fear of lawsuits amongst private practice dentists and OS has not been addressed. We review The American Heart Association/American College of Cardiology, American Dental Association, and American Association of Orthopedic Surgeons’ guidelines on dental antibiotic prophylaxis for the prevention of endocarditis and prosthetic joint infections. We provide experience on how to engage private-practice dentists and OS in dental stewardship using a community-based program.
Population Incidence and Mortality of Sepsis in an Urban African Setting, 2013–2016
Authors: Lewis Joseph M , Abouyannis Michael , Katha Grace , Nyirenda Mulinda , Chatsika Grace , Feasey Nicholas A , Rylance Jamie 
Published: November 2019

Abstract

Background
Sepsis is an important cause of mortality globally, although population incidence estimates from low-income settings, including sub-Saharan Africa, are absent. We aimed to estimate sepsis incidence burden using routinely available data from a large urban hospital in Malawi.

Methods
We linked routine-care databases at Queen Elizabeth Central Hospital, Blantyre, Malawi, to provide admission and discharge data for 217 149 adults from 2013–2016. Using a definition of sepsis based on systemic inflammatory response syndrome criteria and Blantyre census population data, we calculated population incidence estimates of sepsis and severe sepsis and used negative binomial regression to assess for trends over time. Missing data were multiply imputed with chained equations.

Results
We estimate that the incidence rate of emergency department–attending sepsis and severe sepsis in adults was 1772 per 100 000 person-years (95% confidence interval [CI], 1754–1789) and 303 per 100 000 person-years (95% CI, 295–310), respectively, between 2013 and 2016, with a year-on-year decrease in incidence. In-hospital mortality for patients admitted to the hospital with sepsis and severe sepsis was 23.7% (95% CI, 22.7–24.7%) and 28.1% (95% CI, 26.1 – 30.0%), respectively, with no clear change over time.

Conclusions
Sepsis incidence is higher in Blantyre, Malawi, than in high-income settings, from where the majority of sepsis incidence data are derived. Worldwide sepsis burden is likely to be underestimated, and data from low-income countries are needed to inform the public health response.

Published: November 2019

Abstract

Background
Restless legs syndrome (RLS) is characterized by an urge to move the extremities, accompanied by paraesthesiae, in the evening and at night. Uraemic RLS, a type of secondary RLS, occurs commonly in chronic kidney disease and end-stage renal disease. Progression of uraemic RLS over time is unclear. Therefore we investigated the prevalence, progression over time, risk factors and impact on survival of uraemic RLS in a cohort of dialysis patients.

Methods
We reviewed at the 7-year follow-up a cohort of haemodialysis (HD) patients we had previously investigated for RLS, through interviews, validated questionnaires and analysis of demographic and clinical data.

Results
At the 7-year follow-up, RLS was present in 16% of patients, with a persistence rate of 33%. A correlation was obtained between RLS and older age, diabetes, low albumin and low body mass index. RLS was associated with reduced overall survival (median survival of 3.3 versus 3.7 years), particularly with the continuous form of RLS (1.61 years). There was a higher incidence of myocardial infarction and peripheral vascular disease, although not reaching statistical significance. RLS patients had absolute higher scores in all quality of life domains. A large majority of study patients (96%) reported being symptom-free within a few days or weeks following kidney transplantation.

Conclusions
The development of RLS, especially the continuous form, in patients undergoing HD has important consequences associated with decreased survival. Our results indicated an association between uraemic RLS and ageing, diabetes and malnutrition. Considerable efforts should be focused on the treatment of RLS, since it significantly and persistently impacts the quality of life of HD patients. Kidney transplantation could represent an effective treatment option for that RLS impacts on dialysis patients' quality of life, thus confirming the secondary nature of RLS in most HD patients.

Abstract

Aims
To evaluate the relationships between pulmonary transit time (PTT), cardiac function, and pulmonary haemodynamics in patients with heart failure with reduced ejection fraction (HFrEF) and to explore how PTT performs in detecting pulmonary hypertension (PH).

Methods and results
In this prospective study, 57 patients with advanced HFrEF [49 men, 51 years ± 8, mean left ventricular (LV) ejection fraction 26% ± 8] underwent echocardiography, right heart catheterization, and cardiac computed tomography (CT). PTT was measured as the time interval between peaks of attenuation in right ventricle (RV) and LV and was compared between patients with or without PH and 15 controls. PTT was significantly longer in HFrEF patients with PH (21 s) than in those without PH (11 s) and controls (8 s) (P &lt; 0.001) but not between patients without PH and controls (P = 0.109). PTT was positively correlated with pulmonary artery wedge pressure (PAWP) (r = 0.74), mean pulmonary artery pressure (r = 0.68), N-terminal pro-B-type natriuretic peptide (r = 0.60), mitral (r = 0.54), and tricuspid (r = 0.37) regurgitation grades, as well as with LV, RV, and left atrial volumes (r from 0.39 to 0.64) (P &lt; 0.01). PTT was negatively correlated with cardiac index (r = −0.63) as well as with LV (r = −0.66) and RV (r = −0.74) ejection fractions. PAWP, cardiac index, mitral regurgitation grade, and RV end-diastolic volume were all independent predictors of PTT. PTT value ≥14 s best-detected PH with 91% sensitivity and 88% specificity (area under the receiver operating characteristic curve: 0.95).

Conclusion
In patients with HFrEF, PTT correlates with cardiac function and pulmonary haemodynamics, is determined by four independent parameters, and performs well in detecting PH.
Asymptomatic phaeochromocytoma in a patient with Holt-Oram syndrome: a case report
Authors: Ng Perryn , Deepak Doddabele , Teo Lynette , Low Ting Ting 
Published: November 2019

AbstractBackgroundHolt-Oram syndrome (HOS) is a rare congenital disease that affects the heart and upper limbs. Phaeochromocytoma, a catecholamine-secreting tumour, is a rare neuroendocrine disorder. We present an interesting case presentation of these two rare disorders in a patient who was asymptomatic for phaeochromocytoma.Case summaryA 28-year-old woman who was diagnosed at birth with HOS, presented to the hospital with heart failure. She has a past medical history of corrected cyanotic congenital heart disease. She presented with dyspnoea but she did not have headaches, tremors, or diaphoresis. Cardiac magnetic resonance scan was done to investigate the cause of her heart failure and revealed right ventricular systolic dysfunction and a suspicious adrenal lesion. Magnetic resonance imaging adrenal confirmed the presence of the adrenal lesion and concerns were raised for a possible phaeochromocytoma. Biochemical tests showed raised plasma free metanephrine levels. Gallium-68 DOTA positron emission tomography scan showed intense right adrenal gland uptake in keeping with diagnosis of phaeochromocytoma.DiscussionPhaeochromocytoma appears to be more prevalent in patients who are in a chronic hypoxic state. This hypoxic state has been postulated to cause the proliferation of adrenal tissue and therefore the formation of phaeochromocytomas. The hypoxia-inducing factor, which is increased in patients with phaeochromocytoma, has been identified as one of the key factors driving this process as it modulates genes that regulate angiogenesis and proliferation. Congenital heart defects seen in HOS can progress to cyanotic heart disease if left uncorrected and may have been the driver for the development of phaeochromocytoma in our patient.
Citizen consultation and organized breast cancer screening
Authors: Gocko Xavier , Spiga Radia , Chel Virginie , Court Anthony , Plotton Catherine 
Published: November 2019

Abstract
Scientific controversies on breast cancer screening have induced the French authorities to launch online citizen consultation. The objective of this netnography was to identify the knowledge and values underlying contributors’ choices. The choice of supporters was often based on emotions: impression of disease severity and efficacy of screening, fearfulness stemming from personal experience and testimony from relatives. Opponents emphasized the risks of the screening and the doctors’ perceived lack of relational and technical skills. The ‘non-decision’ profile was explained by information deemed simplistic, guilt-inducing and partial. Future research should focus on how to appeal to emotions to support shared decision.
WHY DON’T OLDER ADULTS USE SENIOR CENTERS? EVIDENCE FROM A SAMPLE OF MASSACHUSETTS ADULTS AGE 50 AND OLDER

Published: November 2019

Abstract
Senior centers are an integral community resource, providing programs and services intended to meet the vast range of needs and interests of older adults. There is a growing literature describing senior center participants and benefits to participation, but little is known about those who choose not to participate at a local senior center. This presentation uniquely characterizes non-users of senior centers, based on a sample of community-dwelling adults aged 50+ from seven communities in Massachusetts (N = 9,462). To date, this is the largest data set that describes senior center usage. Most of the sample were women (60%) and in the 60-69 age group (36%). More than three quarters of the sample do not use the local senior center (77%). The most common reasons for non-usage were lack of interest (27%) and not feeling old enough (26%). There are significant differences in reasons of non-usage among age groups and gender (p &lt; .001). Younger age groups’ (50-69) most popular reasons for non-usage were not feeling old enough, not having time, inconvenient senior center hours, and not knowing what is offered. In contrast, older age groups (80+) more frequently reported having no interest or using programs elsewhere. Men were more likely to report not being interested and not being familiar with what is offered. Women were more likely to report not having time, inconvenient hours of programming, and using programs elsewhere. Based on results from this study, this presentation will outline implications for the future of senior centers and their programming.
