Authors: Wang Liang , Xu Huaping , Zhang Xiaofeng , Zhang Yisheng , Shi Lianghui , Wang Minghai
Published: May 2020

In this study, our aim was to compare the clinical effects of laparoscopic surgery and open surgery for the treatment of colon cancer. From January 2018 to December 2018, a random sample of 398 colon cancer patients was collected. The open abdominal surgery group underwent open surgery,
while the laparoscopic surgery group underwent laparoscopic surgery. The success rate of the two groups, total intraoperative blood loss, length of incision, postoperative bedtime, times of lymph node dissection, and incidence of postoperative complications were compared. Both groups were
provided carbon nanotracers for staining. The intraoperative blood loss of the laparoscopic group was significantly lower than that of the open abdominal group (this difference was statistically significant, P < 0.01). However, the operation time and lymph node dissection were similar
for the laparoscopic group and the open abdominal group (the difference was not statistically significant, P > 0.05). The gastrointestinal function recovery time, hospital stay, and lung infection rate of patients in the laparoscopic group were significantly lower than those of patients
in the open abdominal group. Postoperative bleeding, anastomotic leakage, and wound infection were also observed, but differences between the groups were not statistically significant. The incidence of postoperative complications in the laparoscopic surgery group was lower than that in the
open surgery group (statistically significantly, P < 0.05). Laparoscopic surgery in patients with colon cancer is effective and offers patients improved health, shortened recovery time, and better quality of life. Carbon nanotracers can be used to stain lymph nodes and to make distinguishing
between diseased and normal tissue easier.

Authors: Cao Shenghua , Wu Xiaoqian , Zhao Jianling , Jia Xinhong
Published: May 2020

To investigate the inhibitory effect of new nano silver (nAg-NPs) on Klebsiella pneumoniae producing extended spectrum β-lactamases (EBLs). Clinical interventions are mainly directed to inpatients, or patients with obvious discomfort, symptoms, and signs needing outpatient
examination, referral, and clear diagnosis. We randomly selected 88 patients from the rehabilitation department of our hospital from November 2017 to June 2019, and divided them into observation and control groups by drawing lots. Taking ESBL K. pneumoniae as the research object, the
bactericidal effect of nAg-NPs was determined using the coating method; the minimal inhibitory concentration (MIC) was measured using the broth microdilution method, and the mechanism of action of nAg-NPs on ESBL K. pneumoniae was evaluated by electron microscopy. After the implementation
of different nursing management modes, the incidence of risk events in the observation group was significantly lower than that in the control group, and nursing satisfaction was significantly higher than that in the control group. nAg-NPs (≥0.5 g/mL) had 100% bactericidal effect on ESBL
K. pneumoniae, 0.05 g/mL nAg-NPs had obvious bactericidal effect on ESBL K. pneumoniae, 5 g/mL nAg-NPs had obvious bactericidal effect on ESBL K. pneumoniae for 5, 15, 30 and 60 min. Additionally, nAg-NPs showed 3.12 g/mL of MIC. Furthermore, nAg-NPs had a significant
effect on the morphology of K. pneumoniae. nAg-NPs shows obvious inhibitory effect on ESBL K. pneumoniae. These results will provide an experimental basis for the further study and clinical application of nAg-NPs with the help of clinical nurses.

Authors: Niu Jinyan , Shi Xiushan , Yang Yuan
Published: May 2020

To study the clinical effect of psychological nursing on cardiovascular patients undergoing coronary angiography. Sixty cardiovascular patients in our hospital who needed coronary angiography were randomly divided into two groups (30 in each group); contrast agents based on gold nanoparticles
were used for all patients. The experimental group received psychological nursing alongside conventional nursing care, and the control group received only conventional nursing care. The two groups were compared for ease of receiving coronary angiography, medical imaging, anxiety, depression,
blood pressure, heart rate, efficacy, and patient satisfaction. A gold nanoparticle contrast agent has very low toxicity to cardiovascular endothelial cells, good biocompatibility, and a metabolic effect in vivo. Compared to the control group, the coronary angiography in the experimental group
was easier; the medical images were clearer; patients’ anxiety, depression, blood pressure, and heart rate decreased; and curative effect and patient satisfaction were higher. Psychological nursing may significantly improve the psychological and physical condition of cardiovascular patients
undergoing coronary angiography, effectively improve the efficacy as well as satisfaction of patients, and has obvious application value in clinical treatment. Similarly, gold nanoparticle contrast agents have important value in the clinical application of coronary angiography.
A Preliminary Study of the Effects of the Tilburg Frailty Indicator, Frailty Phenotype, and Silver Nanoparticle-Silver Needle Therapy in Senile Inpatients with Frailty
Authors: Xie Jun , Yu Qigui , Yang Linlin , Sun Yuanyuan
Published: May 2020

This study aimed to determine the effects of Tilburg Frailty Indicator (TFI) and frailty phenotype (FP) in senile inpatients with frailty and provide a reference for the clinical evaluation of debilitating elderly patients. The effect of silver nanoparticle (AgNP)-silver needle acupuncture
was also evaluated. Overall, 48 elderly inpatients with an average age of 69.5±6.2 years were included in the study. The results of two weakness assessment methods in screening the same elderly population were compared, and the correlation or consistency between the two methods was
analyzed. A AgNPsilver needle was used for acupuncture treatment. The TFI score ranged from 0 to 12, with an average score of 4.0±0.7 (frailty [TFI>5] in 22 elderly patients [45.8%] and non-frailty in 26 patients [54.2%]). FP was presented in different stages, and the FP score ranged
from 0 to 5, with an average score of 2.1±1.4, including non-frailty in 12 (25%) patients and pre-frailty in 19 (39.6%) patients. Moreover, 17 patients (35.4%) were debilitated. The two assessment methods showed that the degree of debilitation increased with advancing age in the elderly.
The TFI score was positively associated with the defined stage of FP (r = 0.911, P <0.001). The consistency of TFI grading with phenotypic definition kappa value was 0.786 (P <0.001), and the area under the curve was 0.872 (95% confidence interval, 0.834–1.000;
P <0.05). After acupuncture and moxibustion, the patient’s condition evidently improved. In this study, the proportion of non-debilitating elderly hospitalized patients was higher than that of debilitating elderly hospitalized patients, and the degree of debilitating increased
with advancing age. The TFI score was positively associated with the stage of phenotypic definition, and TFI frailty assessment was highly sensitive. Both methods had screening value, but TFI was more effective in screening patients with pre-frailty than FP, resulting in the early intervention
and treatment of debilitating elderly hospitalized patients. A silver needle acupuncture can be used for treating senile frailty, providing a new idea for the clinical treatment of frailty.

To summarize the experience of 40 patients with pancreatic adenocarcinoma treated with irreversible electroporation ablation (IRE), their experiences with surgical nurses, and to explore the best nursing methods before and during IRE ablation. Preoperative visits were conducted to assess
the condition of patients, and psychological counseling was subsequently given to them. All material and medication required for the operation were prepared in advance, and placed in appropriate locations. All 40 patients were treated successfully. The mean time of IRE ablation was 63.33±12.26
(range, 37–87) minutes, and mean blood loss was 2.09±0.49 (range: 1.0–2.8) mL. There were no ablation-related deaths. Skillful mastery of nanoknife usage and troubleshooting methods, intensive observation of patients’ vital signs during ablation, and active cooperation
with surgeons can ensure successful ablation and can reduce the influence of improper nursing during ablation on patients’ prognosis.

Published: May 2020

With increase in incidence of multidrug resistant pathogens, there is a demand to adapt newer approaches in order to combat these diseases as traditional therapy is insufficient for their treatment. Use of nanotechnology provides a promising alternative as antimicrobial agents as against
traditional antibiotics. Metal oxides have been exploited for a long times for their antimicrobial properties. Zinc oxide nanoparticles (ZnO NPs) are preferred over other metal oxide nanoparticles because of their bio-compatible nature and excellent antibacterial potentials. The basic mechanism
of bactericidal nature of ZnO nanoparticles includes physical contact between ZnO nanoparticles and the bacterial cell wall, generation of reactive oxygen species (ROS) as well as free radicals and release of Zn2+ ions. This review focuses on different synthesis methods of ZnO nanoparticles,
various analytical techniques frequently used for testing antibacterial properties, mechanism explaining antibacterial nature of ZnO nanoparticles as well as different factors affecting the antibacterial properties.

Authors: Bangari Raghubeer S. , Sinha Niraj
Published: May 2020

In this study, we report the synthesis and characterization of boron nitride nanosheets (BNNSs), and their application as an adsorbent to remove the cationic dyes methylene blue (MB) and rhodamine B (RhB) from contaminated water. The synthesized adsorbent was characterized by high-resolution
transmission electron microscopy (HR-TEM), field emission electron microscopy (FE-SEM), X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR) and nitrogen adsorption–desorption isotherm. Detailed experiments and analysis were performed on various molar ratios of boron
and nitrogen precursors (1:5 to 1:48) to achieve maximize specific surface area of BNNSs. Among all, the samples synthesized with boric acid and urea (1:30) dissolved in water and methanol produced maximum specific surface area (1801.9 m2 g−1). Further, the adsorption
study was performed in batches by investigating various adsorption parameters such as effect of pH, contact time, adsorbent dose and adsorption isotherm. The pH study revealed that optimum value was found to be at pH 8. It was found through the kinetic study that pseudo-second-order (PSO)
kinetic model was followed by the adsorbent during the adsorption of both the dyes. Further, the adsorption isotherm data well fitted with Langmuir isotherm model. The maximum adsorption capacities of MB and RhB were found to be 333.33 and 312.5 mg g−1, respectively. This
demonstrates the potential of BNNSs as novel adsorbent for treatment of dye-contaminated water.

Published: May 2020

This paper aims to discuss a comprehensive survey on clustering algorithms for wireless sensor networks (WSN). The several real-time applications adopted the WSN with the advance features. But the capacity and size of the battery used in the sensor nodes are limited. Battery replacement
or recharging is very difficult in most outdoor applications. Hence handling this kind of network is one of the issues. One of the best solutions to the energy issue is Clustering. Clustering is to balance the energy consumption of the whole network by cluster-based architecture to prolong
the network lifetime. Sensor nodes grouped into clusters; one sensor node selects as the cluster head for each cluster. The cluster head sensor node collects the data from their sensor member nodes and forwards them to the sink node. In cluster-based architecture, cluster formation and the
selection of the cluster head node decides the network lifetime. The paper discusses the for and against various clustering algorithms. It suggests the vital parameters for developing energy-efficient clustering algorithms and steps to overcome the limitations.

Authors: Anantharamaiah P. N. , Giri Sweta
Published: May 2020

Single-phase spinel cobalt oxide (Co3O4) and copper-substituted cobalt oxide (Co2.8Cu0.2O4) nanomaterials were synthesized via a co-precipitation route. To explore the potential applicability of the Co3O4 and
Co2.8Cu0.2O4 materials for gas sensor fabrication, their SO2 gas sensing characteristics were studied at three different temperatures using the gas concentration of 3 ppm. Unsubstituted Co3O4 sample exhibits poor response towards
SO2 gas whereas the Cu-substituted sample showed superior gas sensing characteristics such as gas response, response time and recovery time at all three temperatures. Among the three studied temperatures, the maximum gas response of 7.5% was found at 200 °C with recovery and
response times of 26 sec, indicating an optimal temperature. Our results demonstrate that the nanostructured Co2.8Cu0.2O4 material could be a potential candidate to design SO2 gas sensor for detection of low concentration gas.

Authors: Yu Hong , Cao Maoyong , Zhu Tanbo , Liu Fanming
Published: May 2020

Sulfur hexafluoride (SF6) gas has been used to gas-insulated switchgear (GIS) because of its insulation properties and extinguishing characteristics. The processing of liquid sulfur hexafluoride from cylinders into GIS is endothermic. The processing gas inflation always leads
to decrease SF6 gas inflation speed due to the lack of heat supplement and the infiltrated moisture will stick on the GIS equipment, especially at the valve outlet. In the paper, a heater detection device for sulfur hexafluoride (SF6) steel cylinder is developed. The
new heater device will monitor and display the specific temperature and humidity of the valve outlet instantaneously and then heat and dry the sulfur hexafluoride (SF6) steel cylinder with automatic and stability. Then it helps to speed up the sulfur hexafluoride gasification. Meanwhile,
the whole device is portable in safety.

Authors: Holmes Thomas , Makary Chadi , Unsal Aykut A. , Biddinger Paul , Reyes-Gelves Camilo , Kountakis Stilianos E.
Published: May 2020

Objectives/Hypothesis:

The presence of eosinophilia and nasal polyps are well-established prognostic indicators of chronic rhinosinusitis (CRS). The importance of demographic background, such as age, as independent variables has not been elucidated while taking these factors into account.

Study Design:

Respective review.

Methods:

CRS patients who underwent primary surgical treatment were subdivided based on age (young adults = age 18-39, adults = age 40-64, and elderly = age 65+). Groups were then subdivided based on tissue eosinophilia and nasal polyposis. Sinonasal Outcome Test (SNOT-22), Lund-Kennedy (LK) endoscopy scores, and Lund-McKay (LM) CT scores were compared preoperatively, and postoperatively during a 5-year period.

Results:

A total of 431 CRS patients identified and then subsequently broken down into 63 young adults (YA), 209 adults (A), and 159 elderly (E). There was no statistical difference between tissue eosinophilia and presence of polyps between the groups. All three groups had similar short- and long-term SNOT-22 patterns postoperatively. At presentation, young adults had significantly higher SNOT-22 score (33.2 YA, 25.3 A, 23.5 E, P = .029) and significantly higher rhinologic scores (1.9 YA, 1.3 A, 1.3 E, P = .0012) than the adult and elderly patients. Objective disease severity using LK endoscopy scores were only significantly higher in young adults at 1-year time ( P = .0026). There was no statistical difference between the groups in regards to preoperative LM CT scores.

Conclusions:

Young adults are more likely to present with overall higher subjective SNOT-22 scores over adults and elderly patients, despite similar objective findings in the groups. Short- and long-term postoperative improvement holds across all age groups.

The effect of processing on the microstructure of hoop-wound composite cylinders
Authors: Lasn Kaspar , Mulelid Mats
Published: May 2020

Fibre-reinforced polymer composites are increasingly used to make pipes and pressure vessels. The relationship between wet-winding manufacturing, composite microstructure, and the mechanical performance is complex due to many process parameters and material properties involved. Efficient manufacturing aspirations however drive process innovations that include new, radically different tow impregnation methods. In this work, the process–property–performance relationship is experimentally construed for hoop-wound carbon fibre/epoxy composite cylinders. The difference between cylinders produced by a new tow impregnation system and cylinders from the reference impregnation system was investigated. Winding speed and cylinder wall thickness were considered as two additional variables. The results indicate that, within current scope, composite microstructure is relatively insensitive to the winding speed and to final cylinder thickness. Meanwhile, un-optimized changes for tow impregnation affect the void content, the size distribution of voids and the interlaminar failure mode in short beam shear.

Published: May 2020

Tooth extraction results in alveolar bone resorption and is accompanied by postoperative swelling and pain. Maresin 1 (MaR1) is a proresolving lipid mediator produced by macrophages during the resolution phase of inflammation, bridging healing and tissue regeneration. The aim of this study was to examine the effects of MaR1 on tooth extraction socket wound healing in a preclinical rat model. The maxillary right first molars of Sprague-Dawley rats were extracted, and gelatin scaffolds were placed into the sockets with or without MaR1. Topical application was also given twice a week until complete socket wound closure up to 14 d. Immediate postoperative pain was assessed by 3 scores. Histology and microcomputed tomography were used to assess socket bone fill and alveolar ridge dimensional changes at selected dates. The assessments of coded specimens were performed by masked, calibrated examiners. Local application of MaR1 potently accelerated extraction socket healing. Macroscopic and histologic analysis revealed a reduced soft tissue wound opening and more rapid re-epithelialization with MaR1 delivery versus vehicle on socket healing. Under micro–computed tomography analysis, MaR1 (especially at 0.05 μg/μL) stimulated greater socket bone fill at day 10 as compared with the vehicle-treated animals, resulting in less buccal plate resorption and a wider alveolar ridge by day 21. Interestingly, an increased ratio of CD206+:CD68+ macrophages was identified in the sockets with MaR1 application under immunohistochemistry and immunofluorescence analysis. As compared with the vehicle therapy, local delivery of MaR1 reduced immediate postoperative surrogate pain score panels. In summary, MaR1 accelerated extraction wound healing, promoted socket bone fill, preserved alveolar ridge bone, and reduced postoperative pain in vivo with a rodent preclinical model. Local administration of MaR1 offers clinical potential to accelerate extraction socket wound healing for more predictable dental implant reconstruction.
Delayed fatal upper-airway obstruction due to laryngopharyngeal burns and thermal epiglottis
Authors: Dalrymple Alice , Gilbert John D , Byard Roger W
Published: May 2020

A 48-year-old man complained of throat swelling and difficulty swallowing after eating hot food. Several hours later, he collapsed and was observed to be gasping for breath. Bystander and ambulance-initiated cardiopulmonary resuscitation was unsuccessful, and he was pronounced deceased at the scene. At autopsy, the aryepiglottic folds were markedly oedematous, with adjacent areas of mucosal inflammation and necrosis from a recent burn. Death was attributed to upper-airway obstruction due to glottic inlet oedema associated with epiglottic and laryngopharyngeal thermal injury. Although thermal epiglottitis not involving fire is an unusual injury and is rarely fatal, the reported case demonstrates a lethal episode arising from the ingestion of excessively hot food. Thermal epiglottitis therefore represents an uncommon cause of delayed upper-airway obstruction in adults that should be considered in individuals presenting with a sore throat and shortness of breath, particularly if there is a history of hot-food ingestion.
How Do Drug-Death-Bereaved Parents Adjust to Life Without the Deceased? A Qualitative Study
Authors: Titlestad Kristine B. , Stroebe , Margaret , Dyregrov Kari
Published: May 2020

Knowledge about how bereaved persons grieve can enhance quality in providing the support and potential services that they need. We aimed to identify ways in which drug-death-bereaved Norwegian parents go on with their lives and what inhibits or promotes adaptation during their grieving. Reflexive thematic analysis was used to analyze 14 semistructured in-depth interviews. We generated three themes: (I) processing grief emotions, (II) proactive coping, and (III) giving and receiving support and assistance. Processing guilt rumination, reflections on blame and a burden of grief emotions characterized grieving early on. Using cognitive strategies and functional-support-giving were found to be the most frequently used strategies. Oscillation between processing stressors and reorientation to the world promoted adjustment to ongoing life. We discuss characteristics of parents who struggle to reorient and outline important implications for policy and practice.
Mortality Rate, Demographics, and Clinical Attributes of Patients Dying in the Intensive Care Unit of a Comprehensive Cancer Center in Jordan: A Descriptive Study
Authors: Almansour Issa M. , Hasanien Amer A. , Saleh Zyad T.
Published: May 2020

Very little is known about the provision of or the need for palliative care in the Middle East, including Jordan. This study investigated the mortality rate, demographics, and clinical attributes of patients with cancer who had died in the intensive care unit (ICU) of a national cancer center over a 3-year period in Jordan. We reviewed the records of 661 patients who had died and found that the majority of the people were terminally ill at the time of admission (had metastatic cancer, multisystem organ dysfunction, and seriously ill). This approach differs from the usual practice worldwide in which it is uncommon to admit patients with cancer to the ICU at the end of life. Improving end-of-life care in the ICUs in Jordan requires further exploration of the cultural context in which end-of-life care practice occurs in Jordan and developing a palliative care approach that fit with the Islamic and Arabic culture.
Infant Movement Response to Auditory Rhythm
Authors: de l’Etoile Shannon K. , Bennett Christopher , Zopluoglu Cengiz
Published: May 2020

Rhythmic entrainment occurs when an auditory rhythm drives an internal movement oscillator, thus providing a continuous time reference that improves temporal and spatial movement parameters. Entrainment processes and outcomes are well known for adults, but research is lacking for infants who might benefit from diagnosis and treatment of irregular rhythms within biological, sensorimotor, cognitive, and social domains. The present study used a combination of inertial measurement units and custom-made software to determine the amount, tempo, and regularity of movement in 28 infants aged 6-10 months while they were exposed to silence, an irregular rhythmic cue, or a regular rhythmic cue with tempo changes. We also assessed changes in the infants’ movement parameters following a one-week rhythm training protocol. While results revealed no significant effect of auditory condition on amount or tempo of movement, infant movement was significantly more regular when infants were exposed to 120 bpm (beats per minute) than to an irregular rhythmic cue or a 10% faster rhythmic cue (132 bpm). Infants showed no notable changes in movement amount, tempo, or regularity following one week of training involving auditory and physical rhythm. Overall, infants seem to engage in spontaneous movements with or without auditory rhythm but may not show tempo sensitivity through their movements. Increased movement regularity suggests that 120 bpm may be a preferred tempo for infants, at which they are more likely to demonstrate well-timed movements that may reflect interval entrainment. Infants’ auditory-motor systems appear not to respond to a 1-week rhythm training protocol.
A dynamic modeling approach for a high-speed winding system with twin-rotor coupling
Authors: Hou Xi , Wang Yongxing , Feng Pei , Yu Haiyan , Ma Xunxun , Chen Ge
Published: May 2020

This paper continues the previous study and presents a dynamic modeling approach for a high-speed winding system. To meet the requirements of high-speed winding, a twin-rotor coupling structure is adopted in the winding system. It is a complex spindle system, due to its high speed, heavy load, frequency-dependent coupling parameters, and time-varying rotational speed. In this paper, an approach to establishing a finite element model of the winding system is proposed to predict its dynamic behavior characteristics during the winding process. First, the spindle and contact roller models of the discrete single component are developed based on Timoshenko beam theory. Bending, transverse shear effects, and gyroscopic moment are considered in the models. The contact stiffness between the contact roller and the packages to be wound on the spindle is simplified by a nonlinear spring. The contact stiffness is identified by dynamics analysis in ANSYS® 17.0. Next, a fully dynamic model of the winding system, which consists of the spindle subsystem, the contact roller, and the flexible coupling elements, is established. Third, the Newmark method is used to develop the program to solve the dynamic equations in MATLAB® 2013b. Finally, the effects of the supporting system and contact state on the winding system's dynamic response are investigated. The results indicate the model of the winding system presented in this paper is suitable for predicting dynamic performance during the winding process.
Mental health in the kingdom of God
Authors: Cook Christopher C. H.
Published: May 2020

Mental disorders are both common and disabling worldwide. They affect beliefs, emotions, identity and relationships in such a way as to impact upon the very essence of human experience. They are associated with stigma and prejudice, and they disproportionately affect those who are poor and those who belong to marginalized groups within society. Increasing attention has been given in recent years to the importance of spirituality for mental health, but in research it is impossible to distinguish between spirituality and the psychological variables that it purports to influence. Those things that are identified as being the concerns of mental health professionals overlap significantly with the concerns of religion. This overlap is examined here in relationship to the Synoptic Gospel accounts of the mission, ministry and teaching of Jesus. It is proposed that Jesus’ teaching on the kingdom of God was centrally concerned with things that we now consider to be the domain of mental health. For Christians, mental health may be understood as the ability to fulfil vocation within the kingdom of God. A more critical theological understanding of mental health is needed to better inform the mission of the Church of England.
On devotional doubt: consolation in Donald MacKinnon and Christian Wiman
Authors: Delport Khegan
Published: May 2020

This article seeks to unpack an oscillating duality within the work of Donald MacKinnon and Christian Wiman, particularly surrounding the theme of ‘consolation’. Using Geoffrey Hill’s heuristic of neither ‘denying nor taming’ the impress of reality, I suggest the practice of attentive prayer as one route through which these concerns are mutually sustained. Moreover, I also suggest that our language of contingency, as suggested by MacKinnon and Wiman, will need to be refigured in the light of Christology.

Authors: Hung Lee Tsung , Jan Fen-Hauh , Lin Yi Hsien
Published: May 2020

The purpose of the present study is to examine a theoretical model using authentic experience, perceived benefit, perceived cost, and support for tourism development among attendees of the Dajia Mazu Pilgrimage in Taiwan. Overall, 1,244 usable responses were collected and analyzed. Analytic findings indicated that authentic experience and perceived benefits are precedents of support for tourism development. Perceived benefits significantly mediate the relationship between authentic experience and support for tourism development in both first-time and repeat attendees. The present study concludes that an individual who attends a traditional religious festival has authentic experiences of pilgrimage that create perceived benefits and lead to behavior that supports tourism development. The theoretical and managerial implications presented in this article elucidate an original theoretical framework and valuable insights for promoting support for tourism development, potentially also contributing to the literature.
A narrative history of the American Balint Society 1990–2020
Authors: Johnson Alan H. , Milberg Laurel C.
Published: May 2020

An historical narrative tracing the inception, evolution, structure, educational focus, integration with international Balint movements and challenges to future growth of the American Balint Society (ABS) is enlivened and deepened by twelve Balint autobiographies that follow it. The ABS in choosing to create its historical narrative is confronting a vitally important project both for its members, and for many healthcare educators and clinicians. Both are deeply invested in promoting and preserving the integrity of the personal relationship between the provider and the client. The Society is striving not only to understand its past, but to educate itself through a contextual awareness of how to preserve a personal education for future healthcare providers. To truly understand how the Balint enterprise emerged in the USA, one must “hear” from the people who experienced and wanted to share the transformative insights of participation in Balint seminars. To “hear” their stories and to honor the diversity of perspectives within the organization the authors asked ABS members with long and committed involvement to write their personal ”Balint Autobiographies.” These authors tell a collective, personal and professional story that is truly integral with an ABS narrative history. Readers may find, amidst their narratives, gems of insight and instruction about the Balint Seminar process, its leadership and possibly indications of where the ABS could head in the future. However, the real significance of the history of the ABS lies in its potency to stimulate critical reflection on the true purpose(s) of the Society, to elicit new and stronger personal incentives in ABS members, and to initiate challenging, inquiring, and supporting reverberations in the medical-educational-insurance-business-governmental subculture in which it participates.
Enhancing the role of remittances through social capital: Evidence from Indonesian household data
Authors: Pratikto Rulyusa , Yazid Sylvia , Dewi Elisabeth
Published: May 2020

The main purpose of this study is to determine whether remittance-receiving households in Indonesia have truly experienced a measurable increase in their welfare. It focuses on how social capital may enhance the efforts of Indonesia’s female migrant workers to improve their and their family’s welfare at home. Our findings confirm that social capital enhances the impact of remittances by increasing the welfare of the migrant workers and their immediate family members. Remittance-receiving households with strong and wide-ranging social capital tend to use the extra income from remittances more for investment. In turn, this generates future income, which boosts the impacts of their remittances on their overall welfare.
Parenting Outcomes and Predictors of Parenting Satisfaction in the Early Postpartum Period
Authors: Shorey Shefaly , Ying Lau , Yobas Piyanee
Published: May 2020

This study examined the relationships among parenting self-efficacy (PSE), social support, postnatal depression (PND), and predictors of parenting satisfaction in the early postpartum period using a cross-sectional exploratory quantitative design. The hypothetical model was tested among interrelated concepts of outcome variables among 250 parents (125 couples). The structural equation model revealed an adequate fit between the hypothesized model and the data. PSE and spousal support were found to be predictors of parenting satisfaction. PSE was also found to be a predictor of social support. PND was not found to be a predictor of parenting satisfaction. None of the obstetric and demographic factors predicted parenting satisfaction. This is the first study that tested interrelations among crucial parenting outcome variables among fathers and mothers in the early postpartum period. It is important to assess interrelated parenting outcomes among both parents so that support can be provided to ultimately influence parenting satisfaction.
Integration Through Connecting in Explanatory Sequential Mixed Method Studies
Authors: Draucker Claire Burke , Rawl Susan M. , Vode Emilee , Carter-Harris Lisa
Published: May 2020

The purposes of this methods article are to (a) discuss how integration can occur through a connecting approach in explanatory sequential mixed methods studies, (b) describe a connecting strategy developed for a study testing a conceptual model to predict lung cancer screening, and (c) describe three analytic products developed by subsequent integration procedures enabled by the connecting strategy. Connecting occurs when numeric data from a quantitative strand of a study are used to select a sample to be interviewed for a subsequent qualitative strand. Because researchers often do not fully exploit numeric data for this purpose, we developed a multi-step systematic sampling strategy that produced an interview sample of eight subgroups of five persons ( n = 40) whose profiles converged with or diverged from the conceptual model in specified ways. The subgroups facilitated the development of tailored interview guides, in-depth narrative summaries, and exemplar case studies to expand the quantitative findings.

Published: May 2020

Objectives

The aim of this study was to assess inter‑ and intra‑observer agreement of detection and grading of oedema measured by vascular physicians using ultrasonography.

Method

In this observational study, three investigators read 113 videos of ultrasonography of the medial lower leg of 77 patients using a 15–18 MHz linear probe and reported whether oedema was present or not and, if present, to what extent. The videos were selected by the coordinator and sent every two months for a period of six months to the three investigators. Intra‑ and interobserver agreements were calculated using the Fleiss Kappa coefficient, reported with their 95% confidence interval and interpreted using the Landis and Koch values.

Results

Inter-observer agreement as to whether oedema was present or not was 0.88 (0.77–0.98), 0.96 (0.89–1.0) and 0.91 (0.80–1.0) for the first, second and third readings, respectively. The concordance was considered to be “excellent.” Inter-observer agreement as to the severity of oedema was 0.52 (0.38–0.65), 0.53 (0.39–0.66) and 0.61 (0.47–0.75) for the first, second and third readings, respectively. The concordance was “moderate”. Intra-observer reliability for the diagnosis of oedema was only 0.89 (0.70–1.0), 0.93 (0.75–1.0) and 0.92 (0.74–1.0) for the first, second and third reader, respectively, which was “excellent”.

Conclusions

The inter-observer agreement interpreting ultrasound videos using standard probes was excellent. Only moderate agreement in grading the severity of the edema using our arbitrary criteria was shown.
The Rückenfigur: A Note on an Intriguing Rear-View Pictorial Device
Authors: Schott Geoffrey D.
Published: May 2020

The Rückenfigur, a rear-view depiction of a person, is an artistic device which dates back several centuries but became particularly prominent in 19th century in Germany. The adoption of the rear-view presents an intriguing challenge, since the viewer must engage with a figure which sees without visible eyes. Considered here are some of the perceptual issues which arise from this unusual pictorial device.
The gendered impact of the financial crisis: Struggles over social reproduction in Greece
Authors: Daskalaki Maria , Fotaki Marianna , Simosi Maria
Published: May 2020

The global financial crisis has triggered a dramatic transformation of employment in the weakest Eurozone economies. This is evidenced in deteriorating work conditions, limited employee negotiating power, low pay, zero-hours contracts and, most importantly, periods of prolonged unemployment for most of the working population, especially women. We offer a critical analysis of the boundaries of formal and informal, paid and unpaid, productive and reproductive work, and explore how austerity policies implemented in Greece in the aftermath of the global financial crisis have transformed women’s everyday lives. In contributing to critical discussions of neoliberal capitalism and recent feminist geography studies, our empirical study focuses on how women’s struggles over social reproduction unfold in the public and private spheres. It proposes that women’s temporary retreat to unpaid work at home constitutes a form of resistance to intensifying precarisation, and, at times, contributes to the emergence of new collective forms of reproduction.
Capacity-Constrained Bus Bridging Optimization Framework
Authors: Itani Alaa , Srikukenthiran Siva , Shalaby Amer
Published: May 2020

Urban rail systems frequently suffer from unexpected service disruptions, which can result in severe delays and user dissatisfaction. “Bus bridging” is the strategy most commonly applied in responding to rail service interruptions in North America and Europe. Buses are pulled from regular routes and dispatched to serve as shuttles along the disrupted rail segment until regular train service is restored. In determining the required number of buses and source routes, most transit agencies rely on ad hoc approaches based on operational experience and constraints, which do not necessarily alleviate the extensive delays and queue build-ups at affected stations, nor do they minimize system-wide impacts in an optimal manner. This paper proposes a genetic algorithm-based optimization model to determine the optimal number of shuttle buses and route allocation to minimize overall subway- and bus rider delay for any given rail disruption incident. The generated optimal solutions were sensitive to bus-bay capacity constraints along the shuttle service corridor of any given disrupted subway segment, utilizing methods found in the Transit Capacity and Quality of Service Manual. The model was used in an analysis of real-world incident data obtained from the Toronto Transit Commission and supplemented by other passenger and travel time data. The bus bridging toolkit showed strong potential to produce efficient shuttle response plans that reduced the transit user delays by more than 50% while ensuring minimum queue formation at disrupted stations and maximizing the utilization of shuttle buses.
