A Scoping Review of Serial Homicide Geographic Mobility Literature and Four Typologies
Authors: Comerford Caroline V.
Published: February 2021

The study of geographic mobility through geospatial analysis and journey-to-crime approaches has made progress in environmental criminology, finding most offenders commit crime close to their residence. However, extant literature on serial homicide and geographic mobility is scarce, specifically lacking a comprehensive appraisal of relative research. To gain a better understanding of the geographic mobility patterns of serial homicide offenders, we must determine the current status of literature in this area, to figure out where to go in terms of future research. Therefore, the following study is a scoping review of existing literature on geographic mobility and serial homicide and four associated typologies (Holmes & DeBurger’s Geographic typology, Hickey’s Mobility typology, Canter’s Circle typology, and Rossmo’s Hunting Style typology) to achieve the following: (1) Comprehensively evaluate literature regarding serial homicide geographic mobility and four associated typologies to establish the current status of research; (2) uncover potential literature gaps; and (3) provide future research recommendations. Literature sources ( N = 43) on serial homicide and geographic mobility (1985–2018) were examined. While findings recognize the relevance of mobility functions in serial homicide investigations, gaps in literature were evident regarding serial homicide geographic mobility and the four associated typologies. Findings also reveal that systematic research in this field is limited. Policy implications and future research recommendations are discussed.
Pilot study evaluating stereotactic body radiation therapy for feline facial squamous cell carcinomas
Authors: Swan Michaela B , Morrow Deanna M , Lurie David M
Published: February 2021

Objectives

The use of stereotactic body radiation therapy (SBRT) has not been assessed in advanced-stage feline solar-induced facial squamous cell carcinomas (SCCs). The objective of this study was to provide preliminary data on the use and safety profile of coarse fractions administered with an SBRT regime to manage advanced-stage feline solar-induced facial SCCs.

Methods

This retrospective study assessed five cats diagnosed with advanced-stage solar-induced facial SCCs that received SBRT as their primary treatment or, in one cat, following failed surgical intervention. Tumour sites received three fractions totalling 26.25–27 Gy over a 3–5-day period.

Results

All patients developed acute effects following SBRT including alopecia, epilation and erythema. Late effects were mild and included alopecia, variable pigmentation and leukotrichia within radiation fields. All patients were alive at the time of article submission, with overall survival times ranging from 118 to 991 days.

Conclusions and relevance

The results suggest that coarse fractions administered with an SBRT technique is a safe and effective treatment tool for the management of advanced-stage feline solar-induced facial SCCs. These data provide preliminary evidence to support larger, prospective studies evaluating the management of feline facial SCCs with SBRT.
Caring for the divided self: A psychoanalytic exploration of care and identity in organizations
Authors: Driver Michaela
Published: February 2021

The study introduces a Lacanian psychoanalytic approach to the investigation of care in organizations. It examines 52 stories describing how employees care for one another in material and emotional ways and explores how the narration of care becomes mapped on to struggles with unconscious aspects of the self, variously subjugating the self to, and empowering the self from, existing power structures. The study finds that current conceptions of care facilitate an imaginary project to fix identity and therefore privilege a more disempowering practice of care. It also reveals that, if investigated from a Lacanian perspective, care can serve more empowering constructions of identity. Specifically, care can create a space in which divided subjectivity can surface and action can be freed from identity projects and the vulnerabilities to identity control this introduces. Implications for theorizing the function of care in relation to identity are discussed.
The ‘disenchantment’ of traditional acupuncturists in higher education
Authors: Givati Assaf , Berlinsky Shelley
Published: February 2021

Efforts of traditional acupuncturists in the UK to regulate their practice and standardise their training, led, from the mid-1990s, to the launch of acupuncture undergraduate programmes within, or validated by, universities. It appeared as if by so doing acupuncturists were on course to align themselves with ‘scientifically plausible’, state-regulated, allied health professionals, a remarkable development considering the marginality of acupuncture practice outside East Asia, and its paradigmatic tensions with biomedicine. But was it really to be? Based on in-depth interviews with higher education acupuncture educators and an analysis of educational documents published by the leading professional body, we explore the way in which this paradigmatic tension is negotiated within a framework that is dominated by biomedicine. By critically revisiting sociology of professions and anti-colonial analysis, we examine an over two decades long journey of acupuncture educators in academic institutions in the UK. Based on this analysis, we point at some of the challenges that acupuncturists faced in higher education that may have restricted the academic legitimisation of acupuncture and that left them in a position of academic marginality and greater exposure to scrutiny, leading to their academic and mainstreaming ‘disillusionment’. At the same time, by positioning themselves as ‘professional academics’ within higher education institutions and demonstrating professionalism, acupuncture educators were able to demonstrate academic and professional ‘credibility’ and therefore distance themselves from the continuous scrutiny over their ‘biomedical fragility’.
A dislocation-based yield strength model for nano-indentation size effect
Authors: Tao Ping , Ye Fei , Gong Jianming , Barrett Richard A , Leen Seán B
Published: February 2021

This paper presents a dislocation-based yield strength model for the nano-indentation size effect. The model is based on functional expressions involving the densities of statistically stored dislocations and geometrically necessary dislocations. A single-phase austenitic stainless steel (316L) and a ferrite-austenite dual-phase steel (2205) are used here as the case-study materials to validate the proposed model. Experimental testing and finite element modelling of nano-indentation of the two materials are presented. Experimental tests are performed in the indentation load range from 1000[Formula: see text] to 10000[Formula: see text]. For 2205 steel, finite element modelling is performed using a dual-phase microstructure-based model. It is shown that, with consideration of statistically stored dislocations and geometrically necessary dislocations, finite element modelling results can reproduce measured load–displacement curves and hence, the size effect, within an error range of about 5%.
Testing Campus-Class-Technology Theory in Student Engagement: A Large Sample Path Analysis
Authors: Gunuc Selim
Published: February 2021

Student engagement refers to the quality and quantity of students’ psychological, cognitive, emotional and behavioral reactions to in-class and out-of-class academic and social activities to achieve successful learning outcomes. In literature, the Campus-Class-Technology (CCT) theory in student engagement was developed and tested with some models, which had certain limitations. Thus, the present study aimed to test the CCT theory with a new and more advanced model. The study was carried out using the quantitative research design and conducted with 3967 students, and the models were tested using path analysis. The research data were collected using the research instruments regarding student engagement, technology integration and campus climate. Four CCT models were developed and tested. The results revealed that all the models were confirmed. In general, what the models explained in the study was that technology integration and benefiting from campus facilities increased student engagement and student success.
A review on the development of conjugated polymer-based textile thermoelectric generator
Authors: Jangra Vivek , Maity Subhankar , Vishnoi Prashant
Published: February 2021

Thermoelectric (TE) materials based on conjugated/conductive polymers can directly convert heat into electricity, and thus found promising applications in energy scavenging and cooling technologies. The performance of these thermoelectric materials is governed by different parameters like the nature of the material, thermal stability, electrical conductivity, Seebeck coefficient, and thermal conductivity. Although the traditional inorganic semiconductor materials such as PbTe (Lead Telluride), Bi2Te3 (Bismuth Telluride), SiGe (Silicon-Germanium), SnSe (Tin Selenide), and Skutterudite (CoAs2) are giving high performance, they have some inherent limitations, such as poor processability, toxicity, rare availability, and high cost of manufacturing. Whereas, organic conjugated polymers such as polyacetylene (PA), polyaniline (PANi), Poly(3-hexylthiophene) (P3HT), polypyrrole (PPy), poly 3,4-ethylenedioxythiophene (PEDOT), etc. have low cost of synthesis, light in weight, low toxicity and better processibility. Organic textile thermoelectric generators (T-TEG) can be prepared by in-situ polymerization of the conjugated polymers onto textile substrates. This article reviews the preparation, design and performance of these T-TEGs. Various approaches and scopes of improvement of efficiency of the thermoelectric effect of the T-TEGs are discussed. Various potential applications of the T-TEG in different fields are also described.
Prediction of the Therapeutic Effects of Pembrolizumab and Nivolumab in Advanced Non-Small Cell Lung Cancer by Platelet-Derived Microparticles in Circulating Blood

Published: February 2021

Background:

There are limited methods to predict the therapeutic effect of immune checkpoint inhibitors (ICIs). The purpose of this study was to explore the value of circulating microparticles (MPs) in predicting thetherapeutic effects of immunotherapy.

Methods:

A prospective study was conducted at the cancer center of PLA general hospital, including all patients with advanced non-small cell lung cancer (NSCLC) who were treated with pembrolizumab or nivolumab from December 2018 to December 2019. The patients were divided into an immune-related objective response (iOR) group and an immune-related disease progression (iPD) group.The numbers of total MPs, platelet-derived microparticles (PMPs) and T-lymphocyte-derived microparticles (T-LyMPs) at baseline and after immunotherapy were detected using a flow cytometer. Univariate analysis and multivariate logistic regression analysis were used to determine the independent influencing factors.

Results:

We identified 32 patients in the iOR group and 18 patients in the iPD group. No significant difference were found intotal MPs, PMPs and T-LyMPs at the baseline between the 2 groups. While total MPs, PMPs and T-LyMPs in the iPD group were significantly higher than those in the iOR group after immunotherapy(P < 0.05). In the multivariate logistic regression analysis, PMPs ≥80 events/µL after immunotherapy(OR, 7.270; 95% CI, 1.092-48.404, P = 0.04) were associated with disease progression in advanced NSCLC and could independently predict the therapeutic effect of immunotherapy.

Conclusions:

PMPs after immunotherapy independently predicted the therapeutic effects of ICIs, making it possible to monitor the therapeutic effect in real time and rapidly adjust treatment regimens. In addition, this study found for the first time that elevated circulating T-LyMPs were associated with disease progression in advanced NSCLC.
Training data augmentation for deep learning radio frequency systems
Authors: Clark William H , Hauser Steven , Headley William C , Michaels Alan J
Published: February 2021

Applications of machine learning are subject to three major components that contribute to the final performance metrics. Within the category of neural networks, and deep learning specifically, the first two are the architecture for the model being trained and the training approach used. This work focuses on the third component, the data used during training. The primary questions that arise are “what is in the data” and “what within the data matters?” looking into the radio frequency machine learning (RFML) field of automatic modulation classification (AMC) as an example of a tool used for situational awareness, the use of synthetic, captured, and augmented data are examined and compared to provide insights about the quantity and quality of the available data necessary to achieve desired performance levels. Three questions are discussed within this work: (1) how useful a synthetically trained system is expected to be when deployed without considering the environment within the synthesis, (2) how can augmentation be leveraged within the RFML domain, and, lastly, (3) what impact knowledge of degradations to the signal caused by the transmission channel contributes to the performance of a system. In general, the examined data types each make useful contributions to a final application, but captured data germane to the intended use case will always provide more significant information and enable the greatest performance. Despite the benefit of captured data, the difficulties and costs that arise from live collection often make the quantity of data needed to achieve peak performance impractical. This paper helps quantify the balance between real and synthetic data, offering concrete examples where training data is parametrically varied in size and source.

Published: February 2021

Background

Coil embolization of aneurysms of the ophthalmic segment of the internal carotid artery (ICA-OphA ANs) has potential risks of visual complications. We analyzed this risk and focused on the relationship of the ophthalmic artery (OphA) origin with the aneurysm neck.

Methods

From January 2003 to April 2018, 179 unruptured ICA-OphA ANs were treated with endovascular surgery in our institution. Two ruptured and four aneurysms with missing data were excluded. Finally, 173 unruptured aneurysms were included in this study. The aneurysms were classified into three groups according to the location of the OphA origin: Separate, Shared, and Dome type. We retrospectively assessed visual complications based on the relationship between types of aneurysm and postoperative angiographic findings for the OphA.

Results

Visual deficits remained permanent in eleven cases (6.4%). In the Dome type, visual complications were significantly more frequent compared to the Separate type. Change in the OphA flow was significantly associated with a higher complication rate of 2.9%, but patients with changed OphA flow had a significant rate of 7.5% ( p = 0.020). We found no significant difference in the incidence of visual complications concerning the use of perioperative antithrombotic therapy.

Conclusions

The location of OphA origin regarding the aneurysmal neck and postoperative OphA flow were significantly correlated with the visual outcome after coil embolization for ICA-OphA ANs. Post-procedural flow in the OphA was an important factor affecting the rate of ischemic retinal complications. Retinal embolic events occurred with preserved flow in the OphA, albeit at a lower rate.
Assessment of an ultrasound bladder scanner in prostate radiotherapy: A validation study and analysis of bladder filling variability
Authors: Smith L , Gittins J , Ramnarine KV , Chung EML
Published: February 2021

Introduction

During prostate radiotherapy treatment, it is important to ensure the position of the bladder and prostate is consistent between treatments. The aim of this study was to provide a quantitative basis for incorporating ultrasound bladder volume estimates into local practice for prostate radiotherapy.

Methods

Agreement between bladder volume estimates obtained using computed tomography (CT) and ultrasound was assessed. Analysis of bladder volumes between planning and treatment scans was used to quantify expected variations in bladder volume over the course of radiotherapy. Dose–volume statistics were estimated and compared to planned dose constraints to propose a target bladder volume and tolerance.

Results

Bladder volume measurements were obtained from 19 radiotherapy patients using ultrasound and CT. Ultrasound underestimated bladder volume compared to CT with a mean bias of –28 ± 30 ml. Pre-treatment (planning) bladder volumes varied from 71 to 383 ml with a mean of 200 ml. Treatment bladder volumes reduced by more than half in 9% of patients during the course of their treatment, potentially leading to a 30% increase in mean bladder dose. Patients with pre-treatment bladder volumes < 200 ml were most likely to exhibit differences in bladder volume, resulting in ‘out of tolerance’ increases in dose.

Conclusions

A pragmatic individualised drinking protocol, aimed at achieving a minimum ultrasound bladder volume of 200 ml at planning CT, may be beneficial to reproducibility in radiotherapy treatment. Ultrasound measurements prior to treatment should ideally confirm that bladder volume is at least half the volume measured at planning.
Working alongside people with intellectual disabilities who have had difficult experiences: Reflections on trauma-informed care within a service context
Authors: Goad Elisabeth
Published: February 2021

People with intellectual disabilities are more likely to experience adverse childhood experiences than those in the general population. Additionally, the conceptualization of ‘trauma’ is far broader than traditionally understood in order to encompass the far reaching relational nature of people with intellectual disabilities traumatic experiences. This reflective account details the first steps one service took to embrace trauma-informed care as a whole systems approach. The paper is a response to calls following conference presentations about our work, to share the process of the beginning of this journey, it also aims to provide key learning points, practical considerations and questions for reflection in order to support other services to begin their own relationships with trauma-informed care.
Communicating What We Know and What Isn’t So: Science Communication in Psychology
Authors: Lewis Neil A. , Wai Jonathan
Published: February 2021

The field of psychology has a long history of encouraging researchers to disseminate their findings to the broader public. This trend has continued in recent decades in part because of professional psychology organizations reissuing calls to “give psychology away.” This recent wave of calls to give psychology away is different because it has been occurring alongside another movement in the field—the credibility revolution in which psychology has been reckoning with metascientific questions about what exactly psychologists know. This creates a dilemma for the modern psychologist: How is one to “give psychology away” if one is unsure about what is known or what one has to give? In the current article, we discuss strategies for navigating this tension by drawing on insights from the interdisciplinary fields of science communication and persuasion and social influence.
From da Vinci’s Flying Machines to a Theory of the Creative Process
Authors: Güss C. Dominik , Ahmed Sarah , Dörner Dietrich
Published: February 2021

Steps involved in the creative process have been described in previous research, yet the exact nature of the process still remains unclear. In the current study, we take this investigation further, referring to two flying machines developed by Leonardo da Vinci and his other notes. Nine iterative steps are described with a focus on motivation and cognition: (a) vision and curiosity; (b) social recognition; (c) asking questions; (d) analogical thinking; (e) trial and error; (f) abductive reasoning; (g) incubation and forgetting; (h) overinclusive thinking, latent inhibition, and illumination; and (i) schema elaboration. The influence of da Vinci’s socio-historic context is also briefly discussed. The analyses show how general psychological mechanisms can explain extraordinary acts of creativity. The steps discussed can be further formalized in future research to advance the modeling of creativity.
Temporal signals to images: Monitoring the condition of industrial assets with deep learning image processing algorithms

Published: February 2021

The ability to detect anomalies in time series is considered highly valuable in numerous application domains. The sequential nature of time series objects is responsible for an additional feature complexity, ultimately requiring specialized approaches in order to solve the task. Essential characteristics of time series, situated outside the time domain, are often difficult to capture with state-of-the-art anomaly detection methods when no transformations have been applied to the time series. Inspired by the success of deep learning methods in computer vision, several studies have proposed transforming time series into image-like representations, used as inputs for deep learning models, and have led to very promising results in classification tasks. In this paper, we first review the signal to image encoding approaches found in the literature. Second, we propose modifications to some of their original formulations to make them more robust to the variability in large datasets. Third, we compare them on the basis of a common unsupervised task to demonstrate how the choice of the encoding can impact the results when used in the same deep learning architecture. We thus provide a comparison between six encoding algorithms with and without the proposed modifications. The selected encoding methods are Gramian Angular Field, Markov Transition Field, recurrence plot, grey scale encoding, spectrogram, and scalogram. We also compare the results achieved with the raw signal used as input for another deep learning model. We demonstrate that some encodings have a competitive advantage and might be worth considering within a deep learning framework. The comparison is performed on a dataset collected and released by Airbus SAS, containing highly complex vibration measurements from real helicopter flight tests. The different encodings provide competitive results for anomaly detection.
Heart to Heart: A Relation-Alignment Approach to Emotion’s Social Effects
Authors: Parkinson Brian
Published: February 2021

This article integrates arguments and evidence from my 2019 monograph Heart to Heart: How Your Emotions Affect Other People. The central claim is that emotions operate as processes of relation alignment that produce convergence, complementarity, or conflict between two or more people’s orientations to objects. In some cases, relation alignment involves strategic presentation of emotional information for the purpose of regulating other people’s behaviour. In other cases, emotions consolidate from socially distributed reciprocal adjustments of cues, signals, and emerging actions without any explicit registration or communication of emotional meaning by parties to the exchange. The relation-alignment approach provides a fresh perspective on issues relating to emotion’s interpersonal, intragroup, and organizational functions and clarifies how emotions are regulated for social purposes.
The Social Construction of Internet Addiction in China: Youth between Reality and Temporal Autonomy in the Documentary Web Junkie
Authors: Pissin Annika
Published: February 2021

This article addresses issues surrounding the social construction of internet addiction, focusing on conceptualisations of reality, escape, hope, and time. Drawing on a critical realist account of semiosis, the framing of internet addiction in China is analysed using the documentary film Web Junkie as an empirical pivot and point of departure. A contextual overview of relations, interests, and tensions surrounding youth and the internet in China is provided, and the film Web Junkie is briefly presented. The main body of the article consists of a critical analysis of conceptualisations of “reality” and “escape.” The core tension focused on in the analysis is the struggle over time, necessitating engagement with critical thought on hope and utopia. The analysis concludes that struggles over temporal autonomy underlie conflicting claims about “reality” and “escape” that are central to “internet addiction” and its treatment in China today.
Acquiring the Art of Conducting: Deliberate Practice as Part of Professional Learning
Authors: Schmidt Simon , Längler Manuel , Altenbuchner Amelie , Kobl Louisa , Gruber Hans
Published: February 2021

Research was and still is involved in the controversial issue about innate talent or extensive practice as the determinants of excellent performance in a range of domains. This study aims to contribute by presenting an analysis of practice activities in a domain that appears to be particularly suitable—orchestral conducting. Most conductors usually attain expertise in instrument playing prior to commencing conducting studies. Twenty-seven students of German study programs of orchestral conducting (approximately 18.7% of the population) responded to a questionnaire about their practice activities in conducting programs and their instrumental experiences. Descriptive results show the wealth of prestudy experiences conducting students have. A clear influence on practice activities cannot be stated. During study, students rated conducting-specific practice activities as more demanding and devoted more time to them than to general music practice activities. Therefore, conducting-specific practice activities might have been practiced more deliberately than general music practice activities.

Published: February 2021

Natural products and their derivatives have served as powerful therapeutics against pathogenic microorganisms and are the mainstay of our currently available treatment options to combat infections. As part of our ongoing search for antimicrobial natural products from marine organisms, one fraction prepared from the Arctic marine bryozoan Securiflustra securifrons was found to be active against the human pathogenic bacterium Streptococcus agalactiae (gr. B). Chemical investigation of the fraction revealed that it contained several variants of the highly modified secondary metabolites known as securamines. The securamines are alkaloids sharing a common isoprene-histamine-tryptamine backbone. In this study, we describe the antimicrobial activities of securamine C, E, and H – J (4, 5, and 1-3) and the attempt to deconvolute the mode of action of 1.
Preference for Telehealth Sustained Over Three Months at an Outpatient Center for Integrative Medicine
Authors: Finn Michael T. M. , Brown Hannah R. , Friedman Emily R. , Kelly A. Grace , Hansen Kathryn
Published: February 2021

Background

Integrative medicine is a key framework for the treatment of chronic medical conditions, particularly chronic pain conditions. The COVID-19 pandemic prompted rapid implementation of telehealth services.

Objective

We present outcomes of a complete and rapid transition to telehealth visits at an outpatient integrative medicine center in the Southeastern United States.

Method

Patients and administrative staff took surveys comparing telehealth to in-person visits within four weeks of our clinic's transition to telehealth and three months later. Beginning four weeks after the clinic’s telehealth conversion in March 2020, patients who had a telehealth visit at the center completed a survey about their telehealth experience and another survey three months later.

Results

Patient quality judgements significantly favored telehealth at baseline, B = .77 [0.29 – 1.25], SE = .25, t(712) = 3.15, p = .002, and increased at three months, B = .27 [–0.03 – 0.57], SE = .15, t(712) = 1.76, p = .079. Telehealth technology usability and distance from the center predicted patient ratings of telehealth favorability. Providers favored in-person visits more than patients, B = –1.00 [–1.56 – –0.44], SE = .29, t(799) = –3.48, p < .001, though did not favor either in-person or telehealth more than the other. Patient discrete choice between telehealth and in-person visits was split at baseline (in-person: n = 86 [54%]; telehealth: n = 73 [46%]), but favored telehealth at three months (in-person: n = 17 [40%]; telehealth: n = 26 [60%]). Overall, discrete choice favored telehealth at follow-up across providers and patients, OR = 2.69 [.1.18 – 6.14], z = 2.36, p = .018. Major qualitative themes highlight telehealth as acceptable and convenient, with some challenges including technological issues. Some felt a loss of interpersonal connection during telehealth visits, while others felt the opposite.

Conclusion

We report converging mixed-method data on the successful and sustained implementation of telehealth with associated policy and clinical implications during and beyond the COVID-19 pandemic.
The Proverbial Closet: Do Faith and Religiosity Affect Coming Out Patterns?
Authors: Ratcliff Shawn M. , Haltom Trenton M.
Published: February 2021

Disclosing one’s sexual minority identity or “coming out of the closet” is a key milestone in sexual minority identity development. While scholars have explored how race, gender, class, and other social classifications shape coming out patterns among lesbian, gay, or bisexual (LGB) individuals, we know far less about the effect of religious contexts. To address this shortcoming, we extend existing theoretical insights to better understand how faith and religiosity shape coming out patterns among sexual minorities both independently and collectively. Specifically, we examine how religious affiliation and religious attendance (a measure of religiosity) affect when LGB individuals privately realize and publicly disclose their sexual minority identity. Using data from the Pew Research Center’s 2013 Survey of LGBT Adults, we conduct a series of ordinary least squares regressions on a representative sample of LGB adults ( n = 1,136). We find religious contexts—both religious affiliation and attendance—have no independent effect on when a person realizes or publicly discloses their sexual minority identity for the first time. However, evangelical Protestants that frequently attend religious services publicly disclose their sexual minority identity at older ages. These results highlight the social cost of publicly disclosing an LGB identity, especially within conservative religious spaces.
The Healing after Gender-Based Violence Scale (GBV-Heal): An Instrument to Measure Recovery Progress in Women-Identifying Survivors
Authors: Sinko Laura , Schaitkin Chris , Saint Arnault Denise
Published: February 2021

Current literature has primarily equated gender-based violence recovery with an improvement of physical or mental health symptoms, causing a gap in our understanding of the impact of interventions beyond the amelioration of adverse symptomology. The purpose of this research was to create an instrument to holistically measure gender-based violence recovery based on survivor healing goals. Ethnographic interviews were conducted in women-identifying gender-based violence survivors (ages 18–76) to determine healing domains and develop items using survivor language ( n = 56). Focus groups with academic and community experts ( n = 12) and cognitive interviews with gender-based violence survivors ( n = 12) were conducted to ensure content and face validity, as well as to evaluate acceptability. This yielded a 31-item instrument to measure healing progress on a 5-point Likert scale. The Healing after Gender-based Violence Scale has the potential to highlight survivor strength and growth while more accurately measuring their recovery process based on survivor goals and desires.

Published: February 2021

This study explored residential (housing and town) satisfaction of rural older adults aging in place, relating to demographic and housing characteristics. We conducted a structured, face-to-face survey with 149 rural older adults. Regression results revealed that housing satisfaction for rural older adults were significantly related to demographic and housing characteristics, including personal health status, healthy home status, and structure size. Bivariate analysis revealed that satisfaction with a town feature, shopping location, was the most frequently related to demographic and housing variables, followed by cost of living in town; and that health status was most frequently associated with town feature satisfaction. The study results can enhance programs and/or services for older adults aging in rural communities.
Adolescent Risk and Protective Factors for the Use of Electronic Cigarettes
Authors: Burrow-Sánchez Jason J. , Ratcliff Benjamin R.
Published: February 2021

The use of electronic cigarettes (e-cigarettes) by adolescents is a serious public health concern. The major aim of the current study is to conduct a comprehensive examination of adolescent e-cigarette use in relation to risk and protective factors for a school-based sample. The present study is based on a secondary data analysis of the 2017 Prevention Needs Assessment (PNA) Survey that is administered every 2 years in the state of Utah to a large sample of students ( n = 54,853) in Grades 6, 8, 10, and 12 from more than 400 schools. The PNA Survey measures substance use, mental health symptoms, and antisocial behavior as well as their associated risk and protective factors. Almost 9% of adolescents in this study reported using e-cigarettes in the past 30 days. Adolescents who reported infrequent (1–5 days) and frequent (6+ days) use of e-cigarettes also indicated lower levels of protection (e.g., perceived harm) and higher levels of risk (e.g., favorable attitudes) compared with students who did not report using e-cigarettes in the past 30 days. The frequency of adolescent e-cigarette use can distinguish between risk and protective factors. Findings suggest that the risk and protective factors relevant for adolescent alcohol, cannabis, and tobacco use extend to the use of the e-cigarettes. Certain risk factors (e.g., favorable attitudes toward substance use) and protective factors (e.g., perceived risk for use of e-cigarettes) hold promise for preventive interventions in addressing this public health concern.

Published: February 2021

Background: Coronavirus disease 2019 (COVID-19) has greatly impacted pediatric healthcare facilities throughout the United States due to widespread case rescheduling and the implementation of supplementary COVID-19 perioperative protocols. To our knowledge, no studies have investigated the impact of COVID-19 on case volume, surgical timing, or operational aspects of cleft surgical procedures. The aim of this study is to investigate the impact that COVID-19 has had on cleft surgical care at our institution. Methods: A retrospective study comparing cleft surgical care in 2019 (the pre-pandemic cohort) and 2020 (the COVID-19 cohort) was designed. All patients who underwent a cleft surgical procedure from April 1st to August 31st in 2019 and 2020 were included for analysis. Procedures were stratified into 4 groups: primary cleft lip repairs, primary cleft palate repairs, alveolar bone grafting procedures, and revisional/secondary repair procedures. Variables investigated in this study included: surgical volume, number of patients receiving timely surgery, causes for untimely surgery, number of combined cases, number of delayed cases, delay time, time under anesthesia, and procedure length. Results: A total of 191 cleft surgeries, 102 in 2019 and 89 in 2020, were identified during the study period. We observed no statistically significant differences in cleft surgical volume and other investigated variables across all surgical subgroups from 2019 to 2020. Conclusion: Cleft surgical care was largely unaffected by COVID-19 despite high rates of case rescheduling and the addition of supplementary perioperative safety protocols. More studies are needed to assess the impact of COVID-19 on cleft surgical care at other cleft centers and to investigate the long-term outcomes of these patients.
Additional chromosomal abnormalities at chronic myeloid leukemia diagnosis predict an increased risk of progression

Published: February 2021

At diagnosis of chronic-phase chronic myeloid leukemia (CML), there are conflicting data as to whether additional cytogenetic abnormalities (ACAs) beyond a standard Philadelphia (Ph) translocation confer a higher risk of subsequent disease progression. In the United Kingdom SPIRIT2 trial comparing imatinib 400 mg daily with dasatinib 100 mg daily, diagnostic karyotypes were available in 763 of the 814 patients recruited. Of these, 27 had ACAs in either/both the original 4 major route group (trisomy 8 or 19, iso17q or a second Ph) or the 5 additional lesions recently described (trisomy 21, 3q26.2, monosomy 7/7q−, 11q23, and complex karyotypes), and their progression rate was significantly higher (22.2%) than in patients without one of these ACAs (2.2%; P < .001). Patients with ACAs had worse progression-free survival (PFS; hazard ratio [HR], 5.21; 95% confidence interval [CI], 2.59-10.50; P < .001) and freedom from progression (FFP; HR, 12.66; 95% CI, 4.95-32.37; P < .001) compared with patients without ACAs. No association was seen between the Sokal or European Treatment and Outcome Study long-term survival (ELTS) scores and the presence of ACAs. Univariate analysis showed that higher Sokal and ELTS scores and the presence of ACAs were associated with poorer PFS, though only ACAs and high-risk ELTS scores were associated with poorer FFP. Multivariable models identified both the Sokal/ELTS score and ACAs as significant independent factors for PFS but only ELTS score and ACAs as significant independent factors for FFP. The data support the view that certain ACAs are predictive of disease progression independently of Sokal or ELTS scores.

Background

People living with long-term indwelling urinary catheterization at home are increasing globally. Few studies on prevalence have been done globally and none in Sub-Saharan Africa. This study investigated the prevalence and indications of long-term indwelling urinary catheterization (IUC) at home in Northwestern Tanzania and to determine the reasons for staying long with an indwelling urinary catheter after diagnosis of benign prostatic hypertrophy was confirmed.

Methods

This was a cross-sectional study conducted at urology clinic at Bugando Medical Centre, a referral hospital in the Northwestern Zone of Tanzania. The study population included 2112 patients attending the urology clinic from December 2016 to September 2017 with different conditions. From this population, 202 out-patients living with a long-term IUC either suprapubic or urethral were conveniently selected. A review of hospital records of these 202 out-patients was done using a pre-tested checklist. Patients were interviewed to collect additional information. Data were analyzed using STATA version 13(college station, Texas). Descriptive statistics were used for categorical variable, whereas median [inter quartile range (IQR)] was used for continuous variables.

Results

The prevalence of out-patients living at home with an IUC was 9.6% (202/2112), CI (8.4–10.8). Age ranged from 18 to 95 years with the median age of 69 [IQR 61–77] years. Males 195(96.5%) formed the majority of participants. A total of 111 (54.9%) had catheters for ≥ six weeks and 123 (60.9%) had their catheters changed at least once. Common indications were benign prostatic hypertrophy (BPH), 129 (63.9%) and urethral stricture 34 (16.8%). Reasons for the long stay with an IUC at home, especially for those without National Health Insurance Fund (NHIF) 49(94.2%) were endless appointments 23(52.3%), no money to pay for surgery 9(20.5%) and medical conditions 7 (16%). Only 3(0.1%) were under NHIF and were treated promptly.

Conclusion

Prevalence of long-term IUC in Northwestern Tanzania is high. Improved health care system is required to lower the high prevalence of long-term IUC at home through training of more urologists and these patients to be under the scheme of NHIF.
The association between self-efficacy and self-care in essential hypertension: a systematic review
Authors: Tan Felicia Clara Jun Hui , Oka Prawira , Dambha-Miller Hajira , Tan Ngiap Chuan
Published: February 2021

Background

The successful management of hypertension requires sustained engagement in self-care behaviour such as adhering to medication regimens and diet. Bandura’s Social Cognitive Theory suggests that self-efficacy is a major determinant of engagement in self-care behaviour. Self-efficacy refers to an individual’s belief in their capacity to execute behaviours necessary to produce specific performance attainments. This systematic review of observational studies aims to summarise and evaluate the quality of evidence available to support the association between self-efficacy and engagement in self-care behaviour in hypertension.

Methods

Searches were performed of the Pubmed, MEDLINE, CINAHL and OpenSIGLE databases from database inception to January 2020. Reference lists and individual journals were also hand searched. Observational studies in English quantifying self-efficacy and self-care behaviour in hypertensive adults were included. The quality of included articles was assessed with the National Institute of Health Quality Assessment Tool for observational studies.

Results

The literature search identified 102 studies, of which 22 met the inclusion criteria for full-text review. There were 21 studies which reported that higher self-efficacy was associated with engagement in self-care behaviours including medication adherence (n = 9), physical activity (n = 2) and dietary changes (n = 1). Of these, 12 studies were rated as ‘good’ on the quality assessment tool and 10 were ‘fair’. A common limitation in these studies was a lack of objectivity due to their reliance on self-reporting of engagement in self-care behaviour.

Conclusion

Our review suggests an association between self-efficacy and self-care. However, the evidence supporting this association is of low to medium quality and is limited by heterogeneity. Our findings suggest the need for further well-designed interventional studies to investigate this association.

Background

Patient awareness surveys on polypharmacy have been reported previously, but no previous study has examined the effects of sending feedback to health professionals on reducing medication use. Our study aimed to conduct a patient survey to examine factors contributing to polypharmacy, feedback the results to health professionals, and analyze the resulting changes in the number of polypharmacy patients and prescribed medications.

Methods

After conducting a questionnaire survey of patients in Study 1, we provided its results to the healthcare professionals, and then surveyed the number of polypharmacy patients and oral medications using a before-after comparative study design in Study 2. In Study 1, we examined polypharmacy and its contributing factors by performing logistic regression analysis. In Study 2, we performed a t-test and a chi-square test.

Results

In the questionnaire survey, significant differences were found in the following 3 items: age (odds ratio (OR) = 3.14; 95% confidence interval (CI) = 2.01–4.91), number of medical institutions (OR = 2.34; 95%CI = 1.50–3.64), and patients’ difficulty with asking their doctors to deprescribe their medications (OR = 2.21; 95%CI = 1.25–3.90). After the feedback, the number of polypharmacy patients decreased from 175 to 159 individuals and the mean number of prescribed medications per patient decreased from 8.2 to 7.7 (p < 0.001, respectively).

Conclusions

Providing feedback to health professionals on polypharmacy survey results may lead to a decrease in the number of polypharmacy patients. Factors contributing to polypharmacy included age (75 years or older), the number of medical institutions (2 or more institutions), and patients’ difficulty with asking their physicians to deprescribe their medications. Feedback to health professionals reduced the percentage of polypharmacy patients and the number of prescribed medications.
