Review on Recent Advances, Research Trends, and Gas Film in Electrochemical Discharge-Based Micromachining
Authors: Rajput Viveksheel , Goud Mudimallana , Suri Narendra Mohan 
Published: December 2020

AbstractElectrochemical discharge machining (ECDM) is distinguished as a novel process that involves thermal heating and chemical dissolution for the micromachining of “difficult-to-machine” materials like ceramics and quartz. This paper comprehensively reviews the study on gas film, the effect of various input parameters on ECDM performance, such as electrical parameters, electrolyte parameters, and tool electrode parameters, are also likewise discussed. Moreover, a summarized report on thermal modeling, gas film, discrete input parameters, hybridization, and variants in the ECDM process is also provided in a lucid manner. Based on the review, it is concluded that the machining performance of the ECDM process especially in terms of material removal rate (MRR), roughness, tool wear (TW), and thermal cracks is strongly influenced by the input parameters. The formation of the gas film induces variable machining features that can be controlled by altering the machining conditions. Additionally, the paper highlights the future areas that may leads to improve the overall machining performance of the ECDM process.
High Aspect Ratio Machining of Carbon Fiber Reinforced Plastics by Electrical Discharge Machining Process

Published: December 2020

Abstract
Micromachining of carbon fiber reinforced plastics (CFRPs) is essential for numerous applications in several industries such as aerospace, automotive, defense, shipping, sporting goods, and biomedical industries. The major challenge in machining CFRP by electrical discharge machining (EDM) is due to the nonconductivity of epoxy material which is used as a binder for manufacturing these CRFPs. This study attempts a novel, yet simple, approach to ensure the conductivity of the work piece through the entire machining process. Experiments were carried out as a part of this work to assess the feasibility of machining high aspect ratio microholes in CFRP by micro-EDM. The effect of process parameters such as voltage and feed-rate on the hole quality was studied. Using optimal process conditions, microhole of 2500 μm deep with an aspect ratio of over 11 was achieved.

Published: December 2020

Background The extent to which age impacts surgical outcomes remains poorly characterized. This study aims to evaluate the impact of age on 30-day outcomes in patients after distal pancreatectomy. Methods Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2017), distal pancreatectomy patients were identified and age-stratified, groups A (≤75 years) and B (>75 years). Outcomes included 30-day mortality, morbidity, readmissions, operative time (min), and hospital length of stay (LOS, days). Results Of 3042 total patients identified, 1686 (55.4%) were women. A total of 2649 patients (87.1%) were in group A. Overall, both groups had similar baseline characteristics with the exception of the following: diabetes mellitus (24.8% vs. 30.0%, P = .03), smoking (19.3% vs. 4.8%, P < .001), congestive heart failure (.5% vs. 1.8%, P = .010), hypertension (HTN) (47.9% vs. 72.5%, P < .001), bleeding disorders (3.1% vs. 5.3%, P = .036), the American Society of Anesthesiologists (ASA) (III-V) scores (67.6% vs. 85.5%, P < .001), and body mass index (29.2 [±6.7] vs. 27.4 [±5.6], P = .001). Deep surgical site infection was higher in group A (12.1% vs. 6.6%, P = .001), while acute renal failure (ARF) and postoperative myocardial infarction (MI) were higher in group B. 30-day readmissions were higher in group A (17.4% vs. 12.2%, P = .011) despite no statistically significant difference in LOS (7.10 [±6.36] vs. 7.30 [±4.93] days, P = .553) or overall morbidity (29.4% vs. 28.8%, P = .859). Conclusion(s) Those undergoing distal pancreatectomy experienced similar overall morbidity and mortality outcomes regardless of age. However, those older than 75 years had more cardiovascular risk factors, which may have contributed to their higher rates of postoperative ARF and MI.
“The Unheard Voices”: Lived Experiences of Sexual Abuse in Male Survivors
Authors: Das Sarbopriya , Pramanik Soma , Ray Deepshikha , Banerjee Debanjan 
Published: December 2020

Background: Victims of sexual abuse face unique emotional challenges. Among them, the male survivors of sexual assault have largely been neglected in the literature, being traditionally considered “against the norm” and symbolic of reduced masculinity. Methods: Qualitative approach was used to study the lived experiences of five (three heterosexual and two homosexual) male survivors of sexual abuse. In-depth interviews were conducted with consent, transcribed verbatim, and analyzed using interpretative phenomenological analysis (IPA). Results: Commonality in the experiences of abuse (the identity of the abuser, nature of agony), perspectives of sharing the abuse history (lack of acceptance of “male” victimhood, the openness of the opposite gender, family reactions), and the long-term impact of abuse (withdrawal/change of interest as coping, sexual identity issues) emerged as the main superordinate theme (and subthemes). Conclusion: Society, with its patriarchy, often turns apathetic to male victimization in sexual abuse. Beliefs about masculinity and resultant trauma can cause a chronic social and psychosexual impact on the victims. More systematic research is needed to understand their perceptions, unmet needs, and experiences of recovery.

Authors: Nayak Raghavendra B. , Bhatia Triptish , Mahadevaiah Mahesh , Bheemappa A. 
Published: December 2020

Background: In India two thirds of the population is directly or indirectly dependent on agriculture. The suicide rate for farmers throughout the world is higher than the non-farming population with India being no exception. Family members of the household where a member has committed suicide are at an increased risk for depression, anxiety and suicide. There is a paucity of trained counsellors in India, while there is sufficient research showing counselling and therapy through videoconferencing is just as effective as in-person therapy. It is however, not commonly practiced in India, especially in rural settings. We propose to evaluate psychiatric morbidity and assess feasibility and effectiveness of videoconferencing for family members of farmers who had committed suicide. Objectives: The objective is to evaluate family members of farmers who have committed suicide for psychiatric morbidity and psychosocial risk factors. We aim to identify depression, anxiety and suicidal risk in family members and then administer psychological intervention through video-conferencing for depression to study its effectiveness in the cohort. Methodology: The data on completed farmer suicide would be collected from district authorities and police departments. Home visit would be made by research staff to assess the risk factors for the farmers who completed suicide. Family members would be screened for anxiety and depression and severity of depression and suicidal ideas would be rated. The family members having mild to moderate depression would be randomised and CBT based psychological intervention (5 sessions) over three months would be given by trained psychologist through videoconferencing. The outcome would be measured at the end of six months. Conclusions: Psychological interventions through video-conference might be beneficial in the treatment of mild to moderate depression in family members of the farmers who have committed suicide.

Published: December 2020

Objective: To evaluate, psychometrically, a new measure of tearful emotionalism following stroke: Testing Emotionalism After Recent Stroke – Questionnaire (TEARS-Q). Setting: Acute stroke units based in nine Scottish hospitals, in the context of a longitudinal cohort study of post-stroke emotionalism. Subjects: A total of 224 clinically diagnosed stroke survivors recruited between October 1st 2015 and September 30th 2018, within 2 weeks of their stroke. Measures: The measure was the self-report questionnaire TEARS-Q, constructed based on post-stroke tearful emotionalism diagnostic criteria: (i) increased tearfulness, (ii) crying comes on suddenly, with no warning (iii) crying not under usual social control and (iv) crying episodes occur at least once weekly. The reference standard was presence/absence of emotionalism on a diagnostic, semi-structured post-stroke emotionalism interview, administered at the same assessment point. Stroke, mood, cognition and functional outcome measures were also completed by the subjects. Results: A total of 97 subjects were female, with a mean age 65.1 years. 205 subjects had sustained ischaemic stroke. 61 subjects were classified as mild stroke. TEARS-Q was internally consistent (Cronbach’s alpha 0.87). TEARS-Q scores readily discriminated the two groups, with a mean difference of −7.18, 95% CI (−8.07 to −6.29). A cut off score of 2 on TEARS-Q correctly identified 53 of the 61 stroke survivors with tearful emotionalism and 140 of the 156 stroke survivors without tearful emotionalism. One factor accounted for 57% of the item response variance, and all eight TEARS-Q items acceptably discriminated underlying emotionalism. Conclusion: TEARS-Q accurately diagnoses tearful emotionalism after stroke.

Published: December 2020

Background Sinonasal teratocarcinosarcoma (SNTCS) is a highly invasive malignant tumor most frequently found in the nasal cavity and paranasal sinuses. As a result, it can be confused with other sinonasal tumors. In addition, SNTCS progresses rapidly and often infiltrates other tissues or organs in the early phase, resulting in poor patient prognosis. The objective of this article was to report the case of a patient with SNTCS and discuss the management strategy. Furthermore, we conducted a literature review for SNTCS and summarized the findings from 107 cases. Case presentation: Here, we report a 47-year-old man diagnosed with SNTCS and treated with radiochemotherapy after an initial operation. After follow-up for 5 years, no tumor recurrence was observed. Conclusions As SNTCS progresses rapidly, early diagnosis and surgical treatment combined with radiochemotherapy can improve patient survival.

Authors: Garg Shalini , Sangwan Snehlata 
Published: December 2020

Purpose: The article highlights various studies conducted in the field of diversity and inclusion at workplace. This helps us to understand the evolution of diversity and inclusion and identify future research gaps. Methodology: The article employs a citation analysis technique to analyse the citation index of journals and authors based on the data collected from various databases such as Social Sciences Citation Index, Emerging Sources Citation Index, and SCImago (2010–2017). For the analysis, journals relevant to the field of management related to diversity and inclusion in the area of management were selected from the database of 254,617 journals. Finding: A literature review analysis was commissioned to focus on diversity and inclusion at workplace and its research trends from 2010 to 2017. The varied meanings and interpretations of the terms ‘diversity and inclusion’ make it ripe for examining the literature on diversity and that of inclusion to offer a deeper and nuanced understanding of their meanings and conceptualizations. The review analysis suggests that there is a rich body of research in the area of diversity and its related outcomes. Since inclusion has emerged as a fairly recent area of exploration, more research is required in the area of inclusion and its related outcomes. Originality/value: The article is original and holds significance as inclusion has only recently entered the lexicon of popular discourse. Further, this study may benefit research scholars from management seeking understanding about research trends and emerging trends in the area of diversity and inclusion.

Authors: Northwood Korinne , Cabral Sidney , Cutbush Jimsie , Stedman Terry , Parker Stephen 
Published: December 2020

Objectives: Demand for places in postgraduate psychiatry training programmes has increased over recent years. All systems have capacity limits, and concerns have been raised regarding the sustainability of the current intake. This paper presents a modelling exercise to exploring the presence and strategies to resolve bottleneck in the Queensland training programme. Methods: Mathematical modelling based on the RANZCP training regulations and the characteristics of the accredited training programme. Results: A training bottleneck was identified which has been impacted by increased training intake, demand for Advanced Training certificates, and location factors. Conclusions: This investigation raises important questions regarding the future management of postgraduate training in psychiatry in Queensland that may be applicable more widely across Australia and New Zealand. In particular, it highlights the large impact that can result from even small incremental increases in trainees across varying levels of the postgraduate programme and the importance of limiting trainee intake in a manner proportional to the availability of mandatory terms.

Authors: Woodis C. Brock , Ghassemi Emily , McLendon Amber N. 
Published: December 2020

Objective To review the efficacy, safety, and available literature regarding the novel combination bioidentical product Bijuva, or 17β-estradiol/progesterone (17β-E/P), for the treatment of moderate to severe menopausal symptoms in cisgender females with an intact uterus. Data Sources Literature searches of both PubMed (1966 to October 2020) and Google Scholar were conducted using search terms including bioidentical, estradiol, progesterone, menopause, E2/P4, TX-001HR, and Bijuva. Study Selection and Data Extraction All articles with studies conducted in cisgender human females and in the English language were considered for review; 18 publications were included. Data Synthesis In 1 phase 3 clinical study, 17β-E/P was proven to be effective at reducing the frequency and severity of vasomotor symptoms (VMS) at 12 weeks compared with placebo, and no cases of endometrial hyperplasia were observed over the 52-week safety study period. Menopausal women with an intact uterus were included in the study population. Relevance to Patient Care and Practice Concerns over content and safety of compounded bioidentical hormones have been raised by several professional societies. As women experience VMS of menopause, a desire for a Food and Drug Administration–regulated bioidentical combination product for the treatment of moderate to severe menopausal symptoms may be desirable. Given as a once-daily oral capsule at the dose of 1 mg estradiol/100 mg progesterone, 17β-E/P is approved for the treatment of VMS associated with menopause. Conclusions 17β-E/P is a novel bioidentical product that is the first of its kind in the treatment of moderate to severe menopausal symptoms.

Authors: Arbabi Cassra N , Gupta Navyash , Azizzadeh Ali 
Published: December 2020

Objectives Thoracic endovascular aortic repair (TEVAR) is the standard of care for descending thoracic aortic aneurysms (DTAA), and newer generation stent grafts have significant design improvements compared to earlier generation devices. Methods We report the first commercial use of the Medtronic Valiant Navion stent graft for treatment of an 85-year-old woman with a 5.8 cm DTAA and a highly tortuous thoracic aorta. Results A percutaneous TEVAR was performed using a two-piece combination of the Valiant Navion FreeFlo and CoveredSeal stent graft configurations for zones 2–5 coverage. The devices were successfully delievered through highly tortuous anatomy and deployed, excluding the entire length of the aneurysm with precise landing, excellent apposition and no evidence of endoleak. The patient tolerated the procedure well and has had no stent graft-related complications through one-year follow-up. Conclusions Design enhancements such as a lower profile delivery system, better conformability, and a shorter tapered tip are some of the improvements to this third-generation TEVAR device. Coupled with the multiple configuration options available, this gives physicians a better tool to treat thoracic aortic pathologies in patients with challenging anatomy. The early results are encouraging, and evaluation of long-term outcomes will continue.
Predictive value of the transcranial Doppler and mean arterial flow velocity for early detection of cerebral vasospasm in aneurysmal subarachnoid hemorrhage
Authors: Esmael Ahmed , Flifel Mohamed E , Elmarakby Farid , Belal Tamer 
Published: December 2020

Objectives We aimed to predict cerebral vasospasm in acute aneurysmal subarachnoid hemorrhage and to determine the cut-off values of the mean flow velocity by the use of transcranial Doppler. Methods A total of 40 patients with acute aneurysmal subarachnoid hemorrhage were included in this study and classified into two groups. The first group was 26 patients (65%) with cerebral vasospasm and the second group was 14 patients (35%) without vasospasm. Initial evaluation using the Glasgow Coma Scale and the severity of aneurysmal subarachnoid hemorrhage was detected by using both the clinical Hunt and Hess and radiological Fisher grading scales. All patients underwent transcranial Doppler evaluations five times in 10 days measuring the mean flow velocities (MFV) of cerebral arteries. Results Patients with cerebral vasospasm were associated with significantly higher mean Glasgow Coma Scale score ( p = 0.03), significantly higher mean Hunt and Hess scale grades ( p = 0.04), with significantly higher mean diabetes mellitus ( p = 0.03), significantly higher mean systolic blood pressure and diastolic blood pressure ( p = 0.02 and p = 0.005 respectively) and significantly higher MFVs measured within the first 10 days. Logistic regression analysis demonstrated that MFV ≥81 cm/s in the middle cerebral artery is accompanied by an almost five-fold increased risk of vasospasm (OR 4.92, p < 0.01), while MFV ≥63 cm/s in the anterior cerebral artery is accompanied by a three-fold increased risk of vasospasm (OR 3.12, p < 0.01), and MFV ≥42 cm/s in the posterior cerebral artery is accompanied by a two-fold increased risk of vasospasm (OR 2.11, p < 0.05). Conclusion Transcranial Doppler is a useful tool for early detection, monitoring, and prediction of post subarachnoid vasospasm and valuable for early therapeutic intervention before irreversible ischemic neurological deficits take place.
Vascular Assessment in Patients With a Lower Limb Wound: A Correlational Study of Photoplethysmography and Laser Doppler Flowmetry Toe Pressure Techniques
Authors: Patry Jérôme , Laurencelle Louis , Bélisle Justine , Beaumier Maryse 
Published: December 2020

Background: Vascular assessment of the lower limbs is essential in patients with diabetes. In the presence of noncompressible arteries, the ankle brachial index (ABI) can either be inconclusive or provide false-positive results. Toe pressure measurement has been suggested as an alternative as a noninvasive method for detecting peripheral arterial disease (PAD). Toe pressure measurement can be performed either by photoplethysmography (PPG) or by Laser Doppler flowmetry (LDF). The aim of this study was to determine correlations between the two techniques in order to promote the use of PPG in clinical practice. Methods: This was a prospective correlational study of 108 consecutive recruited adult patients, with and without diabetes, with at least one lower limb wound from a University-affiliated hospital wound care clinic. Toe pressure measurements were both performed with PPG and LDF devices. Results: Mean toe pressure values for PPG and LDF were, respectively, 83.7 (SD 35.4) and 79.5 (SD 32.0) mmHg (with a paired t-test 3.969, P < 0.01). In patients with at least one lower limb wound, a strong linear relation was found between PPG and LDF toe pressure techniques with a Pearson’s r correlation coefficient of 0.920 ( P < 0.001). Conclusions: PPG and LDF toe pressure techniques are equivalent in patients with at least one lower limb wound, irrespective of the presence of diabetes. Therefore, in the presence of an ABI with inconclusive results, such as in a patient with noncompressible vessels, both toe pressure techniques can be used for assessing the vascular supply of the lower limb with a wound.
The Private Tutoring Industry in Denmark: Market Making and Modes of Moral Justification
Authors: Christensen Søren , Grønbek Thomas , Bækdahl Frederik 
Published: December 2020

Purpose: The article focuses on the emergence of a private tutoring industry in Denmark over the last decade. Specifically, it explores how private tutoring companies legitimize themselves in a social and cultural context where education has for long predominantly been understood in egalitarian terms. Design/Approach/Methods: The article takes inspiration from Viviana Zelizer’s work on morally controversial markets. It explores the “moral labor” performed by private tutoring companies to redefine the exchange of private tutoring services as a socially wholesome activity. It does so through a close analysis of business information, company websites, and news media articles on private tutoring. Findings: The article argues that, generally, the marketing material of tutoring companies focuses more on social equality and student well-being than on academic success. Thus, the companies predominantly legitimize themselves in terms of long-standing Scandinavian ideals of education. Increasingly, these are also the terms in which the companies criticize mainstream schooling. Originality/Value: The article contributes new knowledge of private tutoring in a Scandinavian context where very little research on the issue has so far been conducted. Theoretically, it relates previous research on “legitimation projects” of private tutoring companies to broader sociological theories on market making.
