‘It Was All a Big Theatre’: Velvet revolutions, ethnic conflicts, and conspiracy theories in Eastern Europe
Authors: Haluzík Radan 
Published: September 2020

AbstractIn 1989 mass democratic – and later nationalist – movements rose up against governments in Eastern Europe and all communist regimes fell like overripe pears. The very speed and ease of this collapse gave rise to speculations and conspiracy theories in the general public, as well as among those who had taken part in the movements themselves. Why did this all happen at once – so suddenly, why did it all go so smoothly, and who organized it all…?!The “staging” of the democratic revolutions (Central Europe) and their subsequent national ethnic conflicts (Yugoslavia, post-Soviet Caucasus), was blamed on diverse causes: the dark political forces of USA, Russia, EU, Germany, international capital, power-hungry politicians, the secret police, and so forth…In this article I wish to record my own experience, as a student activist during the Czechoslovak Velvet Revolution, and as a social anthropologist and war journalist working for several years during the ethnic wars in Yugoslavia and in the Post-Soviet Caucasus.I address the main reasons that prevented understanding the post-communist mass movements and open a space to popular myths and conspiracy theories: 1. tendencies to political theatre, 2. spontaneity and self-organization of mass movements, 3. “mass intoxication” and the internal transformation of the ecstatic actor – activist. Exploring question marks and speculations about these key moments of these mass movements contributes to their understanding.

Objectives: Cannabis use is proposed as a risk factor for psychosis and is associated with depressive disorders. However, the relationship between recreational cannabis use and its longitudinal implications on anxiety conditions is less studied. The aim of this investigation is to systematically evaluate published literature and perform a meta-analysis of the data. Methods: A systematic search was performed of MEDLINE, Embase, and PsychINFO from inception to May 31, 2020, in addition to a hand search. Longitudinal studies that evaluated the relationship of cannabis use and development of anxiety were included. Where applicable, adjusted odds ratios ( ORs) were extracted, pooled, and evaluated using random-effects meta-analysis. Results: After screening of unique abstracts ( n = 6835), the final evaluation included 24 studies, of which 10 reported ORs that were analyzed quantitatively. Cannabis use was significantly associated with increased odds of developing any anxiety conditions ( OR = 1.25; 95% CI, 1.01 to 1.54). Cannabis use was not significantly associated with developing generalized anxiety disorder, panic disorder, or social anxiety disorder. Review of studies not reporting OR revealed mixed results but are suggestive of a link between cannabis use and increased rates/severity of anxiety. Conclusions: Published evidence suggests that cannabis use is likely associated with increased risk of anxiety in the long term but variability of study designs precludes declaration of a causal relationship. Awareness of this association is of relevance for both clinical practice and mental health policy implementation.
Neighborhood Engagement, Dogs, and Life Satisfaction in Older Adulthood

Published: September 2020

Objectives This study examined the relationships between dog ownership, dog walking, and the emotional bond with a dog to neighborhood engagement and life satisfaction among those over age 50. Method Using data from the Health and Retirement Study ( N = 476), two path analysis models were conducted to test the research hypotheses. Results Findings indicated that dog ownership did not have a direct or indirect relationship on life satisfaction. However, time spent in dog walking was associated with frequency of social interactions, which itself had a positive association with life satisfaction. The bond with a dog was not directly associated with life satisfaction but was associated with dog walking. Discussion Dog walking is a promising strategy for simultaneously promoting better health and social engagement, and these factors in turn can promote greater life satisfaction of older adults.
Process Models to Understand Resident-to-Resident Aggression Among Residents With Dementia in Long-Term Care
Authors: Burnes David , Syed Manaal , Hsieh Jessica 
Published: September 2020

Background/Objectives: Resident-to-resident aggression (RRA) is a prevalent form of interpersonal violence in long-term care (LTC) settings. Research to guide preventive interventions is limited. Using social-ecological and need-driven dementia-compromised behavior perspectives, we sought to generate process models representing common RRA pathways in dementia-specific LTC units. Research Methods: We used qualitative focus group methodology involving staff ( n = 36) exposed to everyday resident interactions at two urban LTC facilities in Toronto, Canada. Semistructured interviews were audio-recorded and transcribed. Two independent raters coded the transcripts using iterative, constant comparison analytic processes. Results: Two distinct RRA process models in dementia-specific LTC units were developed. Models reflect sequential pathways driven by residents’ benign or responsive behaviors and cognitive processing limitations, with escalation points within resident dyads or groups. Implications: This study furthers RRA conceptualization as a process rather than an aggressive event. Models capture unique RRA manifestations in dementia-specific LTC units and entrypoints for prevention or management.
Demystifying the Aquatic Paradox: The Infant Mortality in India
Authors: Banerjee Subhanil , Singh Anukriti , Bhattacharya Sumantra , Koner Souren 
Published: September 2020

It is evident that better access to improved water sources will lead to the lessening of infant mortality rate (IMR). However, for India, such inference is ambiguous. There is a strong group of academicians such as Sahu et al. (2015) , Arun et al. (2017) and Tripathy and Mishra (2017) and organizations such as UNICEF that firmly believe that if access to the improved water sources can be improved, then there would be tremendous social welfare and much betterment to the IMR. On the other hand, Banerjee et al. (2020) have refuted such claims and opined that access to improved water sources increases the IMR. The empirical validation of their claim has been flawless, but they are somewhat silent on why such a direct relationship between IMR and improved water source exists. They have made a comment based on assumptions that it might be complacency that develops with access to improved water sources that refrain the people to consider any type of water treatment before passing it to infants for drinking. Such a comment might be valid, but neither is it built upon a sound literature review nor does it stand on strong empirics. At this juncture, the present article tests the claim of Banerjee et al. (2020) based on pure empirics.

Published: September 2020

Objectives: Between 2013 and 2019, an estimated 200 children seeking asylum in Australia were detained on the island of Nauru. In 2018, 15 of these children developed the rare and life-threatening pervasive refusal syndrome (PRS). This paper describes the PRS case cluster, the complexities faced by clinicians managing these cases, and the lessons that can be learned from this outbreak. Conclusions: The emergence of PRS on Nauru highlighted the risks of long-term detention of children in settings that are unable to meet their physical and psycho-social needs. The case cluster also underscored (a) the difficulties faced by doctors working in conditions where their medical and legal obligations may be in direct conflict, and (b) the role of clinicians in patient advocacy.

Published: September 2020

Introduction Breastfeeding rates among young mothers are low and do not meet recommendations from health authorities, putting the health of young mothers and their infants at risk. Young mothers require breastfeeding support that meets their learning needs and preferred mode for accessing information. The objective of this study was to work collaboratively with young mothers in order to cocreate an eHealth breastfeeding resource. Methodology A three-phase exploratory study was conducted in Ontario, Canada. In Phases I and II, young mothers and health care providers (HCPs) were recruited and preferences for an eHealth breastfeeding resource were explored. In Phase III, feedback from young mothers and HCPs about the new resource was collected. Results Participants found the breastfeeding eHealth resource visually appealing, engaging, and informative. Discussion Cocreating a tailored breastfeeding eHealth resource with young mothers and HCPs using a participatory approach ensured that the resource design and content met the learning needs of young mothers.

Objective: The aim of the current study was to introduce and measure the effectiveness of a new 3D-printed nasoalveolar molding (D-NAM) appliance on improving the maxillary arch dimensions (MADs) in infants with unilateral complete cleft lip and palate (UCLP) before surgical lip repair. Design: A prospective, balanced, randomized, parallel groups, single-blinded, controlled trial. Setting: All the steps of the current study were carried in the Department of Orthodontics, Cairo University in Egypt. Participants: Thirty-four, nonsyndromic infants with UCLP. Interventions: The eligible infants were randomly assigned into either no-treatment (control) or to the new D-NAM groups. In D-NAM group, the maxillary models were 3D scanned into virtual models onto which segmentation and alveolar segments approximation were performed. Approximation movements were divided into 3 models representing 3 activation steps. On each of these models, virtual appliance construction was performed followed by 3D printing of the appliance. Nasal stent was added manually to the appliances of the second and third steps. Horizontal tapes were applied to infants in the D-NAM group only. Main Outcomes Measures: A Blinded assessors carried all the MADs measurements virtually on digital models collected at the beginning (T1) and after (T2) treatment. Results: Clinically and/or statistically significant improvements in all the measured MADs were recorded in D-NAM group at T2 before surgical lip repair in comparison to control group. Conclusions: The introduced D-NAM/3D-printed appliance is a simple and efficient technique to improve the MADs in infants with UCLP before surgical lip repair.

Published: September 2020

Background The aim for early extubation remains an important goal in cardiac surgical patients. Therefore, employment of a multimodal approach to pain management that includes a transverse thoracic plane block was retrospectively examined at a single-center tertiary care hospital on the effects of time to extubation, opioid consumption, and length of stay in patients undergoing cardiac surgery via median sternotomy. Methods Blocks were performed on all cardiac surgical patients except for those undergoing left ventricular assist device placement, thoracic transplant, emergent surgery, or redo sternotomy. Following additional exclusions for intra- and postoperative complications unrelated to anesthesia, final analysis was conducted on 75 patients per group. Multimodal pain management included intravenous analgesics and transverse thoracic plane block where patients received 15 mL 0.5% bupivacaine + epinephrine bilaterally under ultrasound guidance prior to incision. Results Following transverse thoracic plane block and multimodal analgesics, 50.6% of patients were extubated in the operation room versus 8.6% in the control group. Intraoperative opioids were decreased, and intensive care unit and total length of stay were reduced by 5 hours and 1 day, respectively, in block patients as compared with controls. Postoperative opioids were not significantly different. There were no reported complications directly attributed to the block. Conclusions The transverse thoracic plane block and multimodal regimen for patients undergoing median sternotomy resulted in a significant number of patients extubated in the operation room without an increase in postoperative re-intubations. Moreover, the block appears to be a quick and safe procedure to utilize on cardiac surgery patients.

Published: September 2020

Purpose: To analyze the relationship between retinal nerve fiber layer thickness (RNFLT) and intraocular pressure (IOP) variation in glaucoma suspects (GS) and patients with primary open-angle glaucoma (POAG). Methods: Thirty-one GS and 34 POAG patients underwent ophthalmologic examination and 24-h IOP measurements. GS had IOPs ranging from 19 to 24 mmHg and/or suspicious appearance of the optic nerve. POAG patients had reproducible abnormal visual fields. We only included patients who presented with short-term IOP fluctuation >6 mm Hg (∆IOP). Only one eye per patient was included through a randomized process. Peripapillary RNFLT was assessed by spectral-domain optical coherence tomography. We correlated RNFLT with IOP parameters. Results: Mean IOP was similar between GS and POAG groups (15.6 ± 3.47 vs 15.6 ± 2.83 mmHg, p = 0.90) as was IOP peak at 6 AM (21.7 ± 3.85 vs 21.3 ± 3.80 mmHg, p = 0.68). Statistically significant negative correlations were found in POAG group between IOP at 6 AM and RNFLT in global ( rs = −0.543; p < 0.001), inferior ( rs = −0.540; p < 0.001), superior ( rs = −0.405; p = 0.009), and nasal quadrants ( rs = −0.561; p < 0.001). Negative correlations were also found between ∆IOP and RNFLT in global ( rs = −0.591; p < 0.001), and all other sectors ( p < 0.05). In GS IOP at 6 AM correlated only with inferior quadrant ( rs = −0.307; p = 0.047). Conclusion: IOP at 6 AM and ∆IOP had negative correlations with RNFLT quadrants in POAG. In GS this correlation occurred between IOP at 6 AM and inferior quadrant. These findings may indicate potential risk factors for glaucoma progression.

Published: September 2020

Introduction: In this case report we report our experience with rescue intra-arterial chemotherapy in a case of multi-relapsed peripapillary Retinoblastoma (RB) and the importance of high resolution MRI in detecting possible optic disc infiltration. Case report: In 2007, a 14 month-old caucasian girl was referred to our ocular oncology unit for leukocoria. Only left eye was interested, with a single mass of the posterior pole. Patient underwent six cycles of systemic chemotherapy and focal laser consolidation. Several relapses occurred during follow-up. Selective intra-arterial chemotherapy (SIAC) with Melphalan was performed and type IV remission was achieved. A new relapse occurred next to the optic disc. MRI was performed and we decided to try to save the globe with a rescue cycle of SIAC. Conclusion: MRI has demonstrated to be useful in decision making in RB, giving us a last chance to save the globe.

Published: September 2020

Aims: To evaluate primary periocular basal cell carcinomas (BCCs) in depth including comparing histological margins with subtype, location and surgical specialty after wide local excision. Methods: A retrospective review was performed for all BCCs excised from three hospitals over 5 years, covering a population of just over 1 million. Tumours were classified according to histological subtype location. Incomplete excision rates and margins were analysed in detail and comparisons made. Results: The most common subtype found was nodular followed by infiltrative. Lesions were most commonly located at the lower lid. Infiltrative BCCs were associated with perineural invasion and incomplete excision despite the largest peripheral margins. Superficial BCCs had the smallest mean peripheral margin but the largest mean deep margin. 2 mm histological margins gave an 83.7% complete excision rate, 6.4% incomplete excision rate and 7.1% where the clearance margin was 0.3 mm or less. Conclusion: Distribution of eyelid BCCs based on subtype and periocular location mirrored the general consensus. Infiltrative BCCs should be excised with wider margins or referred for Mohs surgery, especially if the medial canthus is involved. Superficial BCCs should be excised with wider but shallower surgical margins. Ophthalmologists were more likely than dermatologists or plastic surgeons to incompletely excise a periocular BCC, which is reflective of their more difficult case mix.
Elevated HbA1c is not a risk factor for wound complications following total joint arthroplasty: a prospective study

Published: September 2020

Background: Controversies exist regarding the association of elevated serum glycated haemoglobin (HbA1c) levels and postoperative surgical site infection (SSI) or prosthetic joint infection (PJI) in the setting of total hip and knee arthroplasty (THA and TKA). The purpose of the current study was to determine the prevalence of unknown and uncontrolled diabetes mellitus (DM) in a consecutive series and to investigate the association between postoperative wound complications or SSI/PJI and elevated HbA1c in patients undergoing TJA. Methods: In this prospective single-centre study, HbA1c was determined for patients undergoing elective primary, aseptic or septic revision THA and TKA, between September 2017 and March 2018. Prevalence of DM, unknown and uncontrolled diabetes were reported. Occurrence of 90-day wound healing disorders (WHD) as well as SSI or PJI were observed. Considering the HbA1c threshold ⩾6.5%, a comparative analysis between patients with and without WHD and SSI or PJI for the whole study cohort, as well as for each arthroplasty group, was performed. Receiver operating characteristic (ROC) curves were developed to quantify the predictive power of HbA1c with regard to WHD and infection complications. A total of 1488 patients were included for final analysis. There were 1127 primary THA and TKA (75.7%), 272 aseptic revisions (18.3%) and 89 septic revisions (6.0%). The known diabetic patients constituted 9.9% of the whole study cohort. Results: The majority had uncontrolled DM (67%). Prevalence of unknown DM was 11.1%. The results reveal the prevalence for the German population and might be different in other regions. A total of 57 patients (3.7%) experienced postoperative wound or infectious complications. PJI occurred in only 5 patients (0.03%). There was no significant difference between patients with HbA1c <6.5% and patients with HbA1c ⩾6.5% ( p = 0.092). Conclusions: We demonstrated that prevalence of unknown and uncontrolled DM in patients undergoing TJA is increasing, however; routine preoperative determination of the HbA1c value to prevent possible postoperative wound or infectious complications remains debatable. Larger studies investigating the optimal HbA1c level, as well as other predictors are required.

Published: September 2020

Background: Failed reconstruction in cases of severe acetabular bone loss, with or without pelvic discontinuity, in revision total hip arthroplasty (rTHA) remains a great challenge in orthopaedic surgery. The aim of this study was to describe the outcome of a “second” rTHA with “custom-made acetabular components (CMACs)” after a previously failed reconstruction with CMACs. Methods: 4 patients with severe acetabular bone loss (Paprosky Type IIIB), who required a second rTHA after a previously failed reconstruction with CMAC, due to prosthetic joint infection (PJI), were included in our retrospective study. All prostheses had been constructed on the basis of thin-layer computed-tomography scans of the pelvis. The second rTHA was considered unsuccessful in the event of PJI or aseptic loosening (AL) with need for renewed CMAC explantation. Results: The treatment success rate after second rTHA with a CMAC was 50% (2 of 4). In the successful cases, the visual analogue scale (VAS) score and Harris Hip Score (HHS) after the second rTHA (VAS range 2–4; HHS range 45–58 points) did not differ from those after the first rTHA, before onset of symptoms (VAS: range 2–4; HHS: range 47–55 points). In the failed cases, the second CMACs needed to be explanted due to PJI, with renewed detection of previous pathogens. Patients with treatment failure of the second CMAC had required a higher number of revision surgeries after explantation of the first CMAC than patients with a successful outcome. Conclusions: In patients with severe acetabular bone loss and previously failed rTHA with CMACs, repeat rTHA with a CMAC may be a solid treatment option for patients with an “uncomplicated” multi-stage procedure, i.e., without persisting infection after explantation of the original CMAC. While the outcome in terms of clinical function does not appear negatively affected by such a “second attempt,” the complication rate and risk of reinfection, nonetheless, is high.
