BackgroundHealth and well-being are better, on average, in countries that are more equal, but less is known about how this benefit is distributed across society. Height is a widely used, objective indicator of child health and predictor of lifelong well-being. We compared the level and slope of social gradients in children’s height in high-income countries with different levels of income inequality, in order to investigate whether children growing up in all socioeconomic circumstances are healthier in more equal countries.MethodsWe conducted a coordinated analysis of data from five cohort studies from countries selected to represent different levels of income inequality (the USA, UK, Australia, the Netherlands and Sweden). We used standardised methods to compare social gradients in children’s height at age 4–6 years, by parent education status and household income. We used linear regression models and predicted height for children with the same age, sex and socioeconomic circumstances in each cohort.ResultsThe total analytic sample was 37 063 children aged 4–6 years. Gradients by parent education and household income varied between cohorts and outcomes. After adjusting for differences in age and sex, children in more equal countries (Sweden, the Netherlands) were taller at all levels of parent education and household income than children in less equal countries (USA, UK and Australia), with the greatest between-country differences among children with less educated parents and lowest household incomes.ConclusionsThe study provides preliminary evidence that children across society do better in more equal countries, with greatest benefit among children from the most disadvantaged socioeconomic groups.

Published: November 2019

This paper is an expansion of our previous work on the synthesis of graphene oxides and reduced graphene oxides from different kinds of oil palm waste-based feedstocks, namely, OPL (oil palm leaf), PKS (palm kernel shell), and EFB (empty fruit bunch). Here, the electrochemical measurements of the resulting reduced graphene oxides derived via mild-temperature annealing reduction of the graphene oxides were accomplished using cyclic voltammetry and galvanostatic charge/discharge processes. The findings put forward their promising features for supercapacitor applications. For instance, the reduced graphene oxide derived using EFB precursor (rGOEFB) which has a BET surface area of 117 m2 g-1exhibits a specific capacitance of 688 F g−1at an applied current density of 0.8 A g-1. This is higher than that observed for reduced graphene oxides derived from oil palm leaf (rGOOPL), palm kernel shell (rGOPKS), and the commercially acquired graphite (rGOCG), which possessed specific capacitance values of 632, 424, and 220 F g−1, respectively. It can be deduced that the specific capacitance of the reduced graphene oxide samples increases in the following order: (rGOCG) < (rGOPKS) < (rGOOPL) < (rGOEFB). In summary, these new classes of carbon-based nanomaterials could be applied as efficient electrode materials for supercapacitor application with potential good performance. With this novel green and sustainable approach, various carbon-based nanomaterials can be fabricated for a broad range of multifunctional applications.

Published: November 2019

Background:
Cardiac dysfunction and cardiovascular events are prevalent among patients with chronic kidney disease without overt obstructive coronary artery disease, but the mechanisms remain poorly understood. Coronary microvascular dysfunction has been proposed as a link between abnormal renal function and impairment of cardiac function and cardiovascular events. We aimed to investigate the relations between chronic kidney disease, coronary microvascular dysfunction, cardiac dysfunction, and adverse cardiovascular outcomes.

Methods:
Patients undergoing cardiac stress positron emission tomography, echocardiogram, and renal function ascertainment at Brigham and Women’s Hospital were studied longitudinally. Patients free of overt coronary (summed stress score <3 and without a history of ischemic heart disease), valvular, and end-organ disease were followed up for the adverse composite outcome of death or hospitalization for myocardial infarction or heart failure. Coronary flow reserve (CFR) was determined from positron emission tomography. Echocardiograms were used to measure cardiac mechanics: diastolic (lateral and septal E/e’) and systolic (global longitudinal, radial, and circumferential strain). Image analyses and event adjudication were blinded. The associations between estimated glomerular filtration rate (eGFR), CFR, diastolic and systolic indices, and adverse cardiovascular outcomes were assessed in adjusted models and mediation analyses.

Results:

Of the 352 patients (median age, 65 years; 63% female; 22% black) studied, 35% had an eGFR <60 mL·min
−1
·1.73 m
−2
, a median left ventricular ejection fraction of 62%, and a median CFR of 1.8. eGFR and CFR were associated with diastolic and systolic indices, as well as future cardiovascular events (all
P
<0.05). In multivariable models, CFR, but not eGFR, was independently associated with cardiac mechanics and cardiovascular events. The associations between eGFR, cardiac mechanics, and cardiovascular events were partly mediated via CFR.

Conclusions:
Coronary microvascular dysfunction, but not eGFR, was independently associated with abnormal cardiac mechanics and an increased risk of cardiovascular events. Coronary microvascular dysfunction may mediate the effect of chronic kidney disease on abnormal cardiac function and cardiovascular events in those without overt coronary artery disease.

Published: November 2019

Background Tracheobronchial injury is a rare and serious outcome of thoracic trauma. The aim of this study was to describe our experience in the management of tracheobronchial injuries. Methods We reviewed the presentation, line of management, and results of all 23 patients (17 males and 6 females) with a mean age of 27.87 years, who presented with traumatic tracheobronchial injuries and were admitted to the level 3 trauma center of our university emergency hospital over an eight-year period. Results Blunt trauma was the leading cause (73.9%) of injury. Bronchoscopy was routinely performed. A right thoracotomy was carried out in 73.9% of patients. The right main bronchus was the most common site of injury (30.4%), followed by the trachea in 26.1%. Pulmonary resection was undertaken in 5 cases. Three operative mortalities were recorded. Conclusion Tracheobronchial injuries can be treated conservatively or ideally by surgical repair which is the core line of treatment. Surgery has excellent outcomes depending on skillful use of bronchoscopy and the surgeon’s experience of the surgical approach and technique.

Published: November 2019

Objective Autoimmune hypothalamitis (AHT) is a rare inflammatory disorder that involves the hypothalamus. It remains unclear whether autoimmune hypophysitis (AH) and AHT represent different diseases or different aspects of the same disease. Thus, further investigation of AHT is required. Methods A retrospective review of medical and pathological records of AHT patients from the Chinese PLA General Hospital were examined from January 1, 2005 to May 1, 2017. Clinical data, treatments, and outcomes were investigated. Results Five female patients were identified (median age, 42.6 years). Symptoms included central diabetes insipidus, hypopituitarism, hyperprolactinemia, headache, and hypothalamic syndrome. The following hormonal deficits were noted: follicle-stimulating hormone, luteinizing hormone, adrenocorticotropic hormone, thyroid stimulating hormone, and growth hormone. One patient underwent high-dose methylprednisolone pulse treatment (HDMPT) and azathioprine plus intensity modulated radiation therapy (IMRT), and two patients underwent HDMPT and two rounds of replacement therapy. During follow-up, one patient died because of non-compliance with therapy and the others were in remission or they recovered. Conclusions AHT had similar MRI results, pathology, and treatment compared with AH. Thus, it may be a subtype of AH, and AHT patients may also show hypothalamic syndrome.
The colorist-historical trauma framework: Implications for culturally responsive practice with African Americans
Authors: Ortega-Williams Anna , Crutchfield Jandel , Hall J Camille 
Published: November 2019

Summary An evolution of thought and practice regarding the relationship of racism to well-being, healing, and trauma continues within social work and the helping professions. Additionally, empirical research on colorism as a key dimension of racism suggests that colorism negatively impacts the psychological and physical well-being of African Americans. However, few studies have examined well-being among African Americans in the context of historical trauma, through the lens of colorism. In this paper, the intersectionality of colorism and historical trauma is explored to inform culturally responsive social work education, practice, and research regarding African American well-being. It is the first step toward developing a colorist-historical trauma framework. The impact of colorism as a function of historical trauma response transmission among African Americans is presented. Findings Advances in culturally responsive practice in social work address the impact of social determinants of health, such as racism. However, the impact of colorism within systemic racism is often unacknowledged. The authors assert that social work practice must attune to the differentiated socioemotional, political, and economic needs that exist among African Americans due to the impact of colorism and historical trauma. An intersectional lens, such as the colorist-historical trauma framework, is essential for culturally responsive practice. Applications The colorist-historical trauma framework contributes to the professional social work discourse aimed at strengthening effective micro-, meso-, and macro-level practice with African Americans for well-being. Implications for social work practice, research, and education are presented.

Published: November 2019

Background:Symptom perception in heart failure has been identified as crucial for effective self-care that is a modifiable factor related to decreased hospital readmission and improved survival.Aims:To review systematically the heart failure symptom perception literature and synthesise knowledge on definition, description, factors and instruments.Methods:We conducted a scoping review including studies reporting patient-reported symptom perception in adults with heart failure. Structured searches were conducted in Medline, PubMed, Embase, CINAHL, PsychINFO, Web of Science, Cochrane, JBI and grey literature. Two authors independently reviewed references for eligibility. Data were charted in tables and results narratively summarised.Results:The search yielded 3057 references, of which 106 were included. The definition of heart failure symptom perception comprised body listening, monitoring signs, recognising, interpreting and labelling symptoms, and furthermore awareness of and assigning meaning to the change. Symptom monitoring, recognition and interpretation were identified as challenging. Symptom perception facilitators include prior heart failure hospitalisation, heart failure self-care maintenance, symptom perception confidence, illness uncertainty and social support. Barriers include knowledge deficits, symptom clusters and lack of tools/materials. Factors with inconsistent impact on symptom perception include age, sex, education, experiences of living with heart failure, comorbidities, cognitive impairment, depression and symptom progression. One instrument measuring all dimensions of heart failure symptom perception was identified.Conclusion:Heart failure symptom perception definition and description have been elucidated. Several factors facilitating or hampering symptom perception are known. Further research is needed to determine a risk profile for poor symptom perception – which can then be taken into consideration when supporting heart failure self-care.

Authors: Wang Yating , Bai Genji , Guo Lili , Chen Wei 
Published: November 2019

Objective: To investigate the application value of apparent diffusion coefficient value in the pathological type, histologic grade, and presence of lymph node metastases of esophageal carcinoma. Materials and Methods: Eighty-six patients with pathologically confirmed esophageal carcinoma were divided into different groups according to pathological type, histological grade, and lymph node status. All patients underwent conventional magnetic resonance imaging and diffusion-weighted imaging scan, and apparent diffusion coefficient values of tumors were measured. Independent sample t test and 1-way variance were used to compare the difference of apparent diffusion coefficient value in different pathological types, histologic grades, and lymph node status. Correlation between the apparent diffusion coefficient value and the histologic grade was evaluated using Spearman rank correlation test. Receiver operating characteristic curve of apparent diffusion coefficient value was generated to evaluate the differential diagnostic efficiency of poorly and well/moderately differentiated esophageal carcinoma. Results: No significant difference was observed in apparent diffusion coefficient value between esophageal squamous cell carcinoma and adenocarcinoma and in patients between those with and without lymph node metastases ( P > .05). The differences of apparent diffusion coefficient value were statistically significant between different histologic grades of esophageal carcinoma ( P < .05). The apparent diffusion coefficient value was positively correlated with histologic grade ( rs = 0.802). The apparent diffusion coefficient value ≤1.25 × 10−3 mm2/s as the cutoff value for diagnosis of poorly differentiated esophageal carcinoma with the sensitivity of 84.3%, and the specificity was 94.3%. Conclusions: The performance of apparent diffusion coefficient value was contributing to predict the histologic grade of esophageal carcinoma, which might increase lesions characterization before choosing the best therapeutic alternative. However, they do not correlate with pathological type and the presence of lymph node metastases of esophageal carcinoma.
Comparative Study of the Social Interactions of Two Differently Designed Long-Term Care Facilities for Individuals With Acquired Brain Injury
Authors: Brodsky David , Shepley Mardelle McCuskey 
Published: November 2019

Aim: This study focused on long-term care (LTC) settings for individuals with acquired brain injury (ABI). The goals were (1) to assess the impact of facility configuration on social interactions between residents and staff and (2) obtain a better understanding of staff and resident perceptions of the built environment. Background: A few studies have explored the relationship between the built environment and social interaction in LTC facilities, but there is little empirical data about ABI-specific LTC facilities. Methods: A literature review was conducted on the impact of the built environment on the LTC of brain injury survivors. Via a questionnaire, staff and residents in two settings, one with patient rooms off corridors and the other with patient rooms surrounding a common space, rated the effectiveness of the built environment in promoting social interaction. Behavioral observation was conducted on 18 residents for a duration of 4 hr per resident. Results: Via questionnaires, staff rated the corridor facility as more effective in promoting social interaction, but no significant differences were found between the assessments of the two resident populations. Contrary to staff questionnaire results, residents in the open configuration facility exhibited more social behaviors. Conclusions: Building configuration may impact social interaction between staff and residents in ABI-specific LTC facilities and potentially impact staff and resident quality of life. However, configuration cannot be viewed in a vacuum; residents’ physical and mental limitations, demographic information, and staff engagement must be also considered.
Evaluation of Efficacy of 3-Dimensional Delta Versus Trapezoidal Condylar Plates in Internal Fixation of Mandibular Subcondylar Fractures: A Clinical Study
Authors: Lata Jeevan , Verma Nitin , Mahajan Sarita 
Published: November 2019

Introduction: Among condylar fractures, surgical treatment is most commonly done for subcondylar fractures. Although 2 plate system is most commonly recommended, specially designed delta plate or trapezoidal condylar single 3-dimensional plate have been found to provide early functional rehabilitation with similar stability. Though studied in vitro, not much in vivo study has been done in clinical scenario. Aim and Objectives: Comparative assessment of functional and radiographic outcomes of patients who underwent subcondylar fracture fixation with trapezoidal and delta condylar plate. Methods: 20 patients presenting with subcondylar fracture requiring open reduction and internal fixation were included in this 2-year study from 2014 to 2016. Patients were randomly assigned to either one of the groups, with 10 being treated by each plate. Patients were evaluated regularly during 3 months follow-up on clinical parameters, such as occlusion, mouth opening, range of jaw movements, and radiologic parameters, such as fracture alignment, plate fracture, plate bending, screw loosening, secondary displacement of condylar fragment and its direction, ramus height, and any deviation. Results: In both groups, statistically significant improvement in occlusion seen from the third day to the third month ( P value = .04). Postoperative mouth opening, right and left lateral movements, and protrusive movements were statistically nonsignificant in both group A and group B. But within a group, improvements in the results were variable with regard to all these parameters at different intervals. Clinical and radiographic complications were nonsignificant in both group A and group B. Conclusion: This study is a preliminary effort to evaluate and compare different special plating systems in the management of condylar fractures with the new 3-dimensional trapezoidal and delta plating system, which gives excellent stability and rigidity. Improvement in occlusion was found to be gradual in both the plating system over a period of 3 months. Delta plate showed significant improvement in mouth opening at all intervals in comparison to Trapezoidal plate. Improvement in protrusive movement was found to be gradual and better with delta plate. A trapezoidal condylar plate holds goods for low subcondylar fractures owing to its wider dimension, though delta plate is versatile for both high and low subcondylar fracture.

Introduction: Mandibular angle fracture is a very common fracture of the mandible. These account for approximately 30% of all fractures. These fractures are treated by many techniques such as open reduction or maxilla-mandibular fixation. These fractures have high complication rate accounting for 0% to 32% postoperatively. Material and Methods: This study was conducted on 50 patient reported in Institute of dental sciences, Bareilly and Rohilkhand medical college and hospital, Bareilly to evaluate the outcome of mandibular angle fracture in our institute. Result: Out of 50 patients of mandibular angle fracture, 30 were treated surgically, 17 were treated conservatively, and 3 patients were not interested in any kind of treatment. Males are more commonly affected and road traffic accidents was a very common cause of angle fracture.
New Leiderman–Khlystov Coefficients for Estimating Engine Full Load Characteristics and Performance
Authors: Szpica Dariusz 
Published: November 2019

AbstractThe paper presents a method of calculating the full load engine characteristics based on the Leiderman–Khlystov relation. Because the values of the coefficients of the discussed function available in literature were determined for obsolete engine designs, an attempt was made to update them. To this end, a chassis dynamometer was used where a database of results had been built for a variety of vehicles. Following the data collection, the coefficients for variety of fueling system (six groups: fuel injected gasoline and turbocharged gasoline, spark ignition LPG I–II and IV generation, naturally aspirated diesel and turbocharged diesel) were determined. The identification of the coefficients was carried out in Matlab-Simulink indicating the applicability of the said function for most of the engines, yet the recent popularity of turbocharged gasoline engines requires an additional analysis of the possibility of use of a different functional description. The full load engine characteristics is a basis for the vehicle performance characteristics and, further, for modeling of traffic in a variety of aspects of the vehicle operation.
