Authors: Poiană D I , Ionel I , Drăghici G 
Published: March 2022

Abstract
The purpose of this paper is to highlight the influence of the dimensional characteristics and mechanical strength characteristics of the pipe material on the diameter of the perforated holes in these long pipes, to maintain the stability of the pipe shape in the perforated area. The research aimed to establish the maximum limit dimensions of holes that can be made in long round pipes with thin walls, through perforating by cold plastic deformation in air, using only a punch applied to on the outside of the pipe, for a particular case of pipe clamping. Following the research, the mathematical relations between the maximum diameters of the holes that can be obtained in round pipes, in correlation with the dimensional characteristics and the mechanical resistance of the material, are presented. The characteristics taken into account are the outer diameter of the pipes, the thickness of the pipe wall, and the permissible resistance to rupture of the part material. In the conclusions, it is specified that the determined mathematical relations allow the construction of variation diagrams and the determination of the maximum possible diameters, for other dimensional characteristics of pipes and for other mechanical strength characteristics of different materials.

Published: March 2022

Abstract
The coronavirus pandemic has severely impacted our day-to-day activities and brought about significant change in all major sectors, especially surface passenger transport. Lockdowns and stay-at-home restrictions have significantly reduced energy demand and consequently CO2 emissions of surface passenger transport. The change in CO2 emissions is calculated from near-real-time activity change data as a function of 3 confinement levels. The activity change and related emission trends reflect changes in the mode of transport during different waves, this can be used to understand mobility trends and patterns when stringent measures are imposed. Consequently, constructive use of this data can help prepare and develop the transport sector in case of another epidemic outbreak or other unprecedented calamities and to build a resilient transport infrastructure post-COVID-19. This study estimates and analyzes the changes in CO2 emissions associated with the public (bus and rail) and private surface passenger transport from March 1st, 2020 to Jan 31st, 2021 in 21 countries. The research period covers the 1st and the 2nd waves of COVID-19 in these countries. A higher activity reduction and consequently CO2 emission reduction is displayed during the 1st wave compared to the 2nd for most countries despite implementing stringent measures during both waves. This is in line with countries adapting to the ‘new normal’ and restarting socio-economic activities. Similarly, public transport recovery is slower than private transport recovery, making it essential to focus on reinforcement and adaptation of public transport infrastructure for the future. The results show that a cumulative 510 Mt CO2 has been reduced over 11 months in 21 countries, compared to pre-pandemic levels. This reduction brings about a 6% drop in transport CO2 emissions and a 1.5% drop in global CO2 emissions. This analysis sheds light on mobility trends and travel behavior of surface passenger transport modes and related CO2 emissions in different countries which can be used to exemplify the path to recovery based on near-real-time data.

Abstract
In the last decade, bioprinting has emerged as a facile technique for fabricating tissues constructs mimicking the architectural complexity and compositional heterogeneity of native tissues. Amongst different bioprinting modalities, extrusion-based bioprinting (EBB) is the most widely used technique. Coaxial bioprinting, a type of EBB, enables fabrication of concentric cell-material layers and enlarges the scope of EBB to mimic several key aspects of native tissues. Over the period of development of bioprinting, tissue constructs integrated with vascular networks, have been one of the major achievements made possible largely by coaxial bioprinting. In this review, current advancements in biofabrication of constructs with coaxial bioprinting are discussed with a focus on different bioinks that are particularly suitable for this modality. This review also expounds the properties of different bioinks suitable for coaxial bioprinting and then analyses the key achievements made by the application of coaxial bioprinting in tissue engineering, drug delivery and in-vitro disease modelling. The major limitations and future perspectives on the critical factors that will determine the ultimate clinical translation of the versatile technique are also presented to the reader.
Effect of processing and accelerated storage on the volatile composition and sensory profile of a tomato soup

Published: March 2022

Abstract
The volatile and sensory profile of pasteurized (95 °C, 18 min) and sterilized (120 °C, 14 min) tomato soup and its changes at accelerated storage conditions (37 °C and 42 °C) were identified, characterized, and correlated by predictive models. Sterilization led to more profound changes over storage compared to pasteurisation, showing enhanced levels of ‘dark’ odour, ‘burnt’ flavour, and ‘complexity’, while pasteurized soup had more pronounced ‘green’ odour, ‘vegetables’ flavour, ‘harmony’, and ‘freshness’. Over time, ‘dark’ and ‘burnt’ significantly increased for sterilized soups, whereas ‘green’ decreased significantly only for sterilized soup stored at 42 °C. The changes of ‘dark’, ‘green’, ‘off-flavour’, ‘burnt’, ‘harmony’, and ‘freshness’ were associated with formation of furans (furfural and 2-acetyl-5-methylfuran), and decline of unsaturated aldehydes like E-2-octenal and E,E-2,4-heptadienal. These compounds were identified to represent potential shelf-life markers, yet more studies on their odour activity in the tomato soup matrix are necessary to understand their contribution to the sensory quality. The construction of partial least squares models allowed the prediction of ‘green’, ‘off-flavour’, ‘burnt’, and ‘freshness’ based on selected volatiles. These models will be important tools in the process of predicting the end of shelf life, but need to be supplemented with consumer acceptability levels.
Treating Caregiver Grief With Narrative Therapy
Authors: Matta Tara 
Published: March 2022

Abstract
Dementia, a devastating neurodegenerative disease with over 10 million new diagnoses each year, is characterized by many symptoms including memory loss .Individuals with memory less experience changes in mood, personality, behavior, cognition and activities of daily living which affect their daily lives. These monumental life shifts often occur rapidly, leaving caregivers unprepared to deal with the changes. Caregivers face a unique situations navigating anticipatory grief and changes in their relationships with their loved ones. Current psychological intervention for caregivers includes utilization of cognitive-behavioral therapy and psychoeducation. More recently, intriguing research has emerged regarding the efficacy of narrative therapy for couples where one partner experiences memory loss. However, treating the anticipatory grief component specifically for caregivers has been largely overlooked in these studies. Narrative therapy revolves around identifying the current story that caregivers utilize as their cognitive framework, helping to find alternative plotlines and to process their newly-built cognitive framework. It involves externalizing the problem (in this case, dementia) and locating strengths that the caregiver and their care receiver share to “fight” the problem. Insights from both the current literature and the field have demonstrated a promising outlook on the use of narrative therapy. Such insights imply a need for more research regarding this modality specifically for caregivers, as its core ideas can be easily disseminated to gerontologists, mental health professionals and caregivers.
The Unhurried Hermeneutics of Anti-Black Violence in Toni Morrison’sParadise
Authors: Castromán Soto Margarita M 
Published: March 2022

AbstractThe opening lines of Toni Morrison’s Paradise (1997) are undeniably some of her most famous: “They shoot the white girl first. With the rest they can take their time. No need to hurry out there… . there is time and the day has just begun” (3). While the novel eventually reveals the identity of those who constitute the “they” of the opening action, in a move that has received much critical attention, it famously leaves the first victim anonymous. This essay, however, draws our attention to “the rest.” What of the infamous black women of Paradise for whom the violence is slow and drawn out or the many more in our country whose names we say to rebuke a system of injustice that continues to insist that there is “no need to hurry” for “there is time and the day has just begun”?Privileging a reading of time over space, the essay puts Morrison’s Paradise in conversation with Rob Nixon’s Slow Violence and the Environmentalism of the Poor (2011) and Moya Bailey’s Misogynoir Transformed: Black Women’s Digital Resistance (2021) in order to address the urgent need for a temporal reframing of anti-Black violence. Paying particular care to what Karla Holloway describes as the “comparative laxity” to which Black women in this country have historically been subjected and the extent to which that comparative laxity persists in the face of spectacular scenes of violence, the essay concludes with an examination of Breonna Taylor’s murder in 2020. It considers how the events that resulted in her death, like the fictional raid that frames Morrison’s novel, are byproducts of white supremacist systems of slow violence and misogynoir designed to wear down the opposition by attrition.

Published: March 2022

Abstract

Purpose:
This study aims to identify the beliefs, attitudes, and opinions of nursing professionals associated with tobacco smoking and its prohibition in a psychiatric hospital in Brazil.

Methods:
Using a cross-sectional epidemiologic study, a total of 73 nursing professionals in a smoke-free psychiatric hospital were interviewed. The Varimax Rotation and the Fisher's exact test at a 5% significance level were used to analyze the responses.

Findings:
Most nursing professionals reported observations of patients becoming calmer after smoking (n = 59, 80.8%) and tobacco withdrawal worsening patients' mental health symptoms, suggesting agreement among professionals that some psychiatric patients need to smoke tobacco. Most respondents stated that patients with mental health disorders have more difficulty with smoking cessation (79.4%) and are less interested in quitting smoking than those without disorders (95.9%). While one-third mentioned having used cigarettes as a reward or bribe, the majority (83.6%) was in favor of continuing the smoking ban, with more support observed from those working on a night shift and those who worked in the public psychiatric wards. Over 71% noted improvements in their health after the smoking ban.

Conclusion:
The nursing professionals were surprised by the effectiveness of the smoking ban and highlighted the improvement in the hospital environment after its implementation.

Clinical relevance:
As trusted healthcare professionals, nurses are essential in the fight against smoking and can contribute to awareness promotion, supporting patients during nicotine withdrawal, and decision-making processes for health policies.
Outcomes and Cost of Reduction of Overriding Pediatric Distal Radius Fractures
Authors: Bradley Hallie , Hartman Courtney A. , Crawford Shellye E. , Ramo Brandon A. 
Published: March 2022

Background:
This study compared radiographic outcomes of pediatric patients undergoing closed reduction of 100% displaced distal radius fractures to a historical, published cohort treated with casting alone. We also examined the expense associated with sedated reduction.

Methods:
Single-center, retrospective cohort study examining radiographic outcomes following reduction of 100% translated distal radius fractures in 50 consecutive pediatric patients. Radiographic outcomes were compared with a historical cohort published by Crawford and colleagues. Charges associated with emergency department (ED) and clinic visits were compared between the reduction cohort and a comparison cohort of 13 patients with fractures not requiring reduction.

Results:
Forty-nine children (mean age 4.7 y) were included in this study. Duration of casting averaged 51 days and ED visit duration was 6.6±2.5 hours. Mean sagittal and coronal angulation at time of injury were 16.4 and 15.6 degrees, respectively, and were 13.2 and 9.4 degrees at the time of final follow-up. All fractures achieved radiographic union. Eighteen patients underwent a total of 21 unexpected cast changes. No patients required repeat sedation or surgical management.
Angulation after casting was significantly better in the reduction cohort compared with the casting-only cohort initially, however, at final follow-up, both coronal and sagittal angulation were significantly worse in the reduction cohort compared with the casting-only cohort (coronal angulation 8.59 vs. 0.75, P<0.0001; sagittal angulation 13.49 vs. 2.2, P<0.0001).
Charge analysis compared 46 patients in the reduction cohort to 13 patients with unreduced fractures from the same institution during the same time period. Mean clinic charges were similar ($1957 vs. $2240, P=0.3008). ED charges were higher in the reduction cohort compared with the nonreduction cohort ($7331 vs. $3501, P<0.001), resulting in higher total charges in the reduction cohort ($9245.04 vs. $5740.99, P<0.001).

Conclusions:
While closed reduction of 100% translated distal radius fractures in the pediatric population improves angulation initially, casting alone may provide similar or better radiographic outcomes, expedited care, reduced patient exposure to the risks of procedural sedation, and avoidance of ED charges associated with procedural sedation.

Comparison of Fusion Rate and Functional Outcome Between Local Cancellous Bone Plus Demineralized Bone Matrix and Local Bone in 1-Level Posterior Lumbar Interbody Fusion
Authors: Ko Sangbong , Jun Chungmu , Nam Junho 
Published: March 2022

Study Design:
Retrospective study with prospectively collected data.

Objective:
The purpose of this study is to investigate the difference in fusion rate and clinical outcome of patients with local bone as filler for the graft and demineralized bone matrix (DBM) plus only the cancellous bone from local bone as a filler for cage in 1-level posterior lumbar interbody fusion (PLIF) with cage.

Summary of Background Data:
Cancellous bone is more advantageous than cortical bone in the local bone for improving bone formation in spine fusion surgery. There are little studies on the difference in fusion rate and reduction of fusion time using only these cancellous bones.

Methods:
Of the 40 patients who underwent 1-level PLIF using cage, 20 patients in group A used local bone and 20 patients in group B used mixture of cancellous bone extracted separately from local bone and commercially available DBM as filler for cage. Changes in fusion rate and intervertebral spacing were measured using lateral radiography, and fusion was determined as nonunion using the Brantigan-Steffee classification. The clinical outcome was evaluated.

Results:
There was no difference in height change over time between the two groups. Regarding union grade, group B showed better union grade than group A. However, no difference in union grade change over time was observed between the 2 groups. In group B, Oswestry Disability Index (ODI), Rolland-Morris Disability Questionnaire (RMDQ), and SF-36 mental component score (MCS) significantly decreased, but there was no difference in change over time.

Conclusions:
In 1-level PLIF for degenerative lumbar disease, better fusion rate was observed in the group that used only cancellous bone from local bone plus DBM than that in the group that used local bone; however, there was no difference in fusion grade change over time in the 2 groups.
Conduit over conduit reconstruction of retracted and fibrosed ileal conduit in severe abdominal adhesions
Authors: Wani Mudassir , Bhat Tahir , Sheriff Matin 
Published: March 2022

Abstract
We report a unique case of a patient who underwent cystectomy with ileal conduit for nonmalignant bladder disease. Patient postoperatively developed stomal necrosis which was managed conservatively but after few months there was severe stomal stenosis and retraction and patient ended up with bilateral nephrostomies. On planned open abdominal exploration with intention to refashion stoma, after resection of distal stenosed segment we found that it was impossible to mobilize proximal portion of conduit due to severe small bowel adhesions. We used a unique approach of creating one more ileal conduit, bringing it as a new stoma on one side and anastomosing its other side with proximal one (ileal conduit over conduit) to augment deficient portion. This technique is not mentioned in the literature and as such we are reporting same as it can help many urologists who may encounter such problems.
Heat-related mortality prediction using low-frequency climate oscillation indices: Case studies of the cities of Montréal and Québec, Canada
Authors: Masselot Pierre , Ouarda Taha B.M.J. , Charron Christian , Campagna Céline , Lavigne Éric , St-Hilaire André , Chebana Fateh , Valois Pierre , Gosselin Pierre 
Published: March 2022

Background:
Heat-related mortality is an increasingly important public health burden that is expected to worsen with climate change. In addition to long-term trends, there are also interannual variations in heat-related mortality that are of interest for efficient planning of health services. Large-scale climate patterns have an important influence on summer weather and therefore constitute important tools to understand and predict the variations in heat-related mortality.

Methods:
In this article, we propose to model summer heat-related mortality using seven climate indices through a two-stage analysis using data covering the period 1981–2018 in two metropolitan areas of the province of Québec (Canada): Montréal and Québec. In the first stage, heat attributable fractions are estimated through a time series regression design and distributed lag nonlinear specification. We consider different definitions of heat. In the second stage, estimated attributable fractions are predicted using climate index curves through a functional linear regression model.

Results:
Results indicate that the Atlantic Multidecadal Oscillation is the best predictor of heat-related mortality in both Montréal and Québec and that it can predict up to 20% of the interannual variability.

Conclusion:
We found evidence that one climate index is predictive of summer heat-related mortality. More research is needed with longer time series and in different spatial contexts. The proposed analysis and the results may nonetheless help public health authorities plan for future mortality related to summer heat.
Low-Dose Ferrous Bisglycinate Chelate Supplementation in Chronic Kidney Disease and Hemodialysis Patients
Authors: Hsu Cheng-Yi , Chen Jui-Ching , Tsai Yu-Cheng , Chen Tzen-Wen 
Published: March 2022

Background:
Provision of parenteral or oral iron supplementation can restore iron stores and maintain stable hemoglobin levels in chronic kidney disease (CKD) and hemodialysis (HD) patients. The route for oral or intravenous (IV) administration of iron depends on the acuity of anemia, costs and patient tolerance. IV iron can restore iron stores rapidly but also carries higher risks for allergy and infection. Oral iron supplementation is limited by high gastrointestinal adverse effects.

Methods:
We conducted an open label trial to study the efficiency of a film-coated iron supplementation tablet, which contains ferrous bisglycinate chelate, vitamin C and folic acid, in CKD stage 3b to 4 and HD patients.

Results:
27 HD patients and 20 CKD patients participated this study. After a 16 week intervention, low dose ferrous bisglycinate chelate improved serum iron concentration (67.8 vs 87.2 mg/dL, p=0.04) and transferrin saturation (24.7% vs 31.3%, p=0.03) in stage 3~4 CKD patients, restored iron loss and maintained stable hemoglobin levels in HD patients. No GI upset events were reported.

Conclusion:
Ferrous bisglycinate chelate is a well-tolerated oral iron supplementation for CKD and HD patients.
Flow diverter manages very small aneurysm of the internal carotid artery
Authors: Lee Chien-Hui , Luo Chao-Bao , Lai Yen-Chun , Chang Feng-Chi , Lin Chung-Jung 
Published: March 2022

Background:
Endovascular aneurysm coiling is a minimally invasive method to manage intracranial aneurysms. However, aneurysm coiling may fail in very small aneurysms (VSAs); thus, flow diverter (FD) is recommended as an alternative in these difficult aneurysms. Herein, we report our experience and outcomes of FD to treat VSA of the internal carotid artery (ICA).

Methods:
Over a 3-year period, a total of 70 patients with 87 unruptured VSAs of the ICA were managed by FD. There were 54 men and 16 women, with a mean age of 57 (range, 41–75) years. We retrospectively assessed the clinical data, aneurysm characteristics, and angiographic as well as clinical outcomes of patients treated by FD and compared with larger aneurysms.

Results:
Fifty aneurysms (58%) were located in the supraclinoid ICA, followed by paraclinoid ICA (n = 31, 36%) and cavernous ICA (n = 6, 7%). Most aneurysms (n = 72, 83%) were between 2 and 3 mm in size. The mean aneurysm size was 2.3 mm (range, 1.5–3 mm). Follow-up angiographic data (mean, 13 months) were available in 54 patients with 68 aneurysms. Successful FD deployment in an ideal position to bride aneurysm was achieved in 86 of 87 aneurysms (99%). Complete obliteration (CO) was achieved in 63 aneurysms (93%). Compared with larger aneurysms (>3 mm), VSAs had the tendency to achieve CO (p < 0.05) in a midterm follow-up. Two patients (2.8%) had intraprocedural complications, including in-stent thrombosis (n = 1) and distal embolism (n = 1). One patient (1.4%) suffered from mild limb weakness.

Conclusion:
The use of FD to manage VSA was technically feasible, and the procedure was simpler than those of larger aneurysms. FD stenting of VSAs was confirmed to be effective and safe and had higher CO rate than those in larger aneurysms in a midterm angiographic follow-up.
