AbstractObjectiveTo report complications and long‐term outcomes after submucosal resections of benign and malignant epithelial rectal masses.Study designRetrospective multicentric study.Sample populationMedical records of 93 dogs at 7 referral hospitals.MethodsRecords were reviewed for surgical time, diagnosis, margins, complications, and recurrences. Survival of dogs was evaluated based on tumor types, categorized as benign, carcinoma in situ, and carcinoma. The Kaplan‐Meier survival curve and Cox proportional hazards analysis were used to determine the association of a range of variables with recurrence and survival time.ResultsDuration of follow up was 708 days (range, 25‐4383). Twenty‐seven dogs (29%) developed complications. Recurrence was identified in 20/93 (21%), with 12/20 recurrent masses treated with repeat submucosal resection. Median survival was not reached in any group. The 1‐,2‐, 5‐year survival rates for carcinomas were 95%, 89%, and 73% respectively. However, overall survival was longer for benign tumors than carcinomas (P = .001). Recurrence was more likely when complications (P = .032) or incomplete margins (P = .023) were present. Recurrence was associated with an increased risk of death (P = .046).ConclusionSubmucosal resection of both benign and malignant rectal masses was associated with a low rate of severe complications and prolonged survival in the 93 dogs described here.Clinical significanceSubmucosal resection is a suitable technique for resection of selected rectal masses.
“Keep the Pace! You’ve Got This!”: The Content and Meaning of Impactful Crowd Encouragement at Mass Running Events
Authors: Gibbs-Nicholls Sophie , McCormick Alister , Coyle Melissa 
Published: January 2022

This study identified helpful and unhelpful encouragement at mass participation running events and explored the meaning that runners found in encouragement. First, 10 k and half-marathon postevent surveys differentiated instructional and motivational components of helpful and unhelpful support. Second, an inductive, reflexive thematic analysis of 14 interviews highlighted the reciprocal relationship between the crowd and runners, whereby quality of support was reflected in runners’ emotions and behavior. Participants drew pride in participation and belief from the crowd, and they wanted to “give back” through doing their best. Personal and authentic support was particularly valued. Although support was widely appreciated, at times it created a pressure to “perform.” As a novel intervention based on our combined findings, we recommend that crowds, event organizers, and psyching teams give encouragement “with IMPACT” (Instructional; Motivational; Personalized; Authentic; Confidence-building; Tailored to the distance). Crowds should also demonstrate the “core conditions” of authenticity, empathy, and being nonjudgmental within their encouragement.
Origin of Symphyotrichum anticostense (Asteraceae, Astereae), an endemic, high polyploid species of the Gulf of St. Lawrence region, based on morphological and nrDNA evidence
Authors: Vaezi Jamil , Brouillet Luc 
Published: January 2022

Symphyotrichum anticostense (Fernald) G.L.Nesom (Asteraceae, Astereae), a rare endemic of the Gulf of St. Lawrence region, is a high allopolyploid (2n = 10x = 80). It has been hypothesized to be derived from the hybrid between tetraploid (2n = 4x = 32) individuals of Symphyotrichum boreale (Torr. & A.Gray) Á.Löve & D.Löve and the hexaploid (2n = 6x = 48) Symphyotrichum novi-belgii (L.) G.L.Nesom. We investigated this hypothesis using morphological and molecular internal transcribed spacer sequence data, and we tried to determine the potentially geographic origins of the taxon. Univariate morphological analyses show that 67.5% of the S. anticostense characters are parent-like, 43.5% from S. novi-belgii and 13% from S. boreale, the remainder not differing statistically from either parent; 23.5% are intermediate and 9% transgressive. Multivariate analyses show that S. anticostense is intermediate between its putative parents. The molecular results support the morphological data, but due to the insufficient resolution among ribotypes on the tree, a more rapidly evolving marker will be needed to more reliably ascertain the origin of S. anticostense. Besides the hypothesis of genetic drift and allele fixation following long-distance dispersals, at least three independent geographic origins may be suggested for S. anticostense; Anticosti Island, Lake St. John, and Gaspé Peninsula-New Brunswick-Maine.
No-go theorem for inflation in an extended Ricci-inverse gravity model
Authors: Do Tuan Q. 
Published: January 2022

AbstractIn this paper, we propose an extension of the Ricci-inverse gravity, which has been proposed recently as a very novel type of fourth-order gravity, by introducing a second order term of the so-called anticurvature scalar as a correction. The main purpose of this paper is that we would like to see whether the extended Ricci-inverse gravity model admits the homogeneous and isotropic Friedmann–Lemaitre–Robertson–Walker metric as its stable inflationary solution. However, a no-go theorem for inflation in this extended Ricci-inverse gravity is shown to appear through a stability analysis based on the dynamical system method. As a result, this no-go theorem implies that it is impossible to have such stable inflation in this extended Ricci-inverse gravity model.
Adequacy of Effective Born for electroweak effects and TauSpinner algorithms for high energy physics simulated samples
Authors: Richter-Was E. , Was Z. 
Published: January 2022

AbstractMatching and comparing the measurements of past and future experiments call for consistency checks of electroweak (EW) calculations used for their interpretation. On the other hand, new calculation schemes of the field theory can be beneficial for precision, even if they may obscure comparisons with earlier results. Over the years, concepts ofImproved Born,Effective Born, as well as of effective couplings, in particular of$$\sin ^2\theta _W^{{\textit{eff}}}$$sin2θWeffmixing angle for EW interactions, have evolved. In our discussion, we use four versions of EW library for phenomenology of practically all HEP accelerator experiments over the last 30 years. We rely on the codes published and archived with the Monte Carlo program for$$e^+e^- \rightarrow f {\bar{f}} n(\gamma )$$e+e-→ff¯n(γ)and available for the as well. re-weighs generated events for introduction of EW effects.

Documentation of upgrade, to version 2.1.0, and that of its new arrangement for semi-automated benchmark plots are provided. In our paper, focus is placed on the numerical results, on the different approximations introduced in Improved Born to obtain Effective Born, which is simpler for applications of strong or QED processes inppor$$e^+e^-$$e+e-colliders.

The irreducible mass of Christodoulou–Ruffini–Hawking mass formula
Authors: Ha Yuan K. 
Published: January 2022

We reveal three new discoveries in black hole physics previously unexplored in the Hawking era. These results are based on the remarkable 1971 discovery of the irreducible mass of the black hole by Christodoulou and Ruffini, and subsequently confirmed by Hawking. (1) The Horizon Mass Theorem states that the mass at the event horizon of any black hole — neutral, charged, or rotating — is always twice its irreducible mass observed at infinity. (2) The External Energy Theorem asserts that the rotational energy of a Kerr black hole exists completely outside the horizon. This is due to the fact that the irreducible mass does not contain rotational energy. (3) The Moment of Inertia Theorem shows that every black hole has a moment of inertia. When the rotation stops, the irreducible mass of a Kerr black hole becomes the moment of inertia of a Schwarzschild black hole. This is recognized as the rotational equivalent of the rest mass of a moving body in relativity. Thus after 50 years, the irreducible mass has gained a new and profound significance. No longer is it a limiting value in rotation, it determines black hole dynamics and structure. What is believed to be a black hole is a mechanical body with an extended structure. Astrophysical black holes are likely to be massive compact objects from which light cannot escape.

Published: January 2022

Introduction An American College of Surgeons (ACS) Level-I (L-I) pediatric trauma center demonstrated successful laparoscopy without conversion to laparotomy in ∼65% of trauma cases. Prior reports have demonstrated differences in outcomes based on ACS level of trauma center. We sought to compare laparoscopy use for blunt abdominal trauma at L-I compared to Level-II (L-II) centers. Methods The Pediatric Trauma Quality Improvement Program was queried (2014-2016) for patients ≤16 years old who underwent any abdominal surgery. Bivariate analyses comparing patients undergoing abdominal surgery at ACS L-I and L-II centers were performed. Results 970 patients underwent abdominal surgery with 14% using laparoscopy. Level-I centers had an increased rate of laparoscopy (15.6% vs 9.7%, P = .019 ); however they had a lower mean Injury Severity Score (16.2 vs 18.5, P = .002) compared to L-II centers. Level-I and L-II centers had similar length of stay ventilator days, and SSIs (all P > .05). Conclusion While use of laparoscopy for pediatric trauma remains low, there was increased use at L-I compared to L-II centers with no difference in LOS or SSIs. Future studies are needed to elucidate which pediatric trauma patients benefit from laparoscopic surgery.

Objectives: This study investigated trends in hospital-treated self-harm and hospital presenting suicidal ideation in the period before and after COVID-19 public health responses by key socio-demographic groups among those presenting to hospitals in the Western Sydney (Australia) population catchment. Methods: Emergency department presentations for the period January 2016 to June 2021 were used to specify a series of interrupted time-series models to compare the observed and expected event rates of (1) hospital-treated self-harm and (2) hospital presenting suicidal ideation in the period following the onset of COVID-19 public health measures in March 2020. Rate differences between observed and expected rates in the post-implementation period were also estimated in models stratified by sex, age group, country of birth and socio-economic status. Results: There was no significant increase in hospital-treated self-harm in the period post-implementation of public health orders (March 2020) compared to the previous period, although there were lower than expected rates of emergency department presentations among non-Australian-born males, males aged 0–14 years and 25–44 years, and females aged 45–64 years. In contrast, there was a significant increase in hospital presenting suicidal ideation, particularly among women (rate difference per 100,000 = 3.91, 95% confidence interval = [1.35, 6.48]) and those aged 15–24 years (both males and females, rate differences ranging from 8.91 to 19.04), and among those residing in lower socio-economic status areas (both males and females, rate differences ranging from 0.90 to 2.33). Conclusion: There was no increase in hospital-treated self-harm rates in the 15 months post-implementation of COVID-19 public health orders in Western Sydney; however, there was a significant increase in hospital presenting suicidal ideation. The limited change in suicidal behaviour may reflect the success of social and economic supports during this period, the benefits of which may have been different for young people, and those of lower socio-economic status.

Objective: This review aimed to measure the degree of placebo response in panic disorder. Data Sources: We searched major databases up to 31 January 2021, for randomized pharmacotherapy trials published in English. Study Selection: A total of 43 studies met inclusion criteria to be in the analysis (with 174 separate outcome measurements). Data Extraction: Changes in outcome measures from baseline in the placebo group were used to estimate modified Cohen’s d effect size. Results: A total of 43 trials (2392 subjects, 174 outcomes using 27 rating scales) were included in the meta-analysis. Overall placebo effect size was 0.57 (95% confidence interval = [0.50, 0.64]), heterogeneity ( I2: 96.3%). Higher placebo effect size was observed among clinician-rated scales compared to patient reports (0.75 vs 0.35) and among general symptom and anxiety scales compared to panic symptoms and depression scales (0.92 and 0.64 vs 0.56 and 0.54, respectively). There was an upward trend in effect size over the publication period ( r = 0.02, p = 0.002) that was only significant among clinician-rated scales ( r = 0.02, p = 0.011). There was no significant publication bias, Egger’s test ( p = 0.08). Conclusion: We observed a substantial placebo effect size in panic disorder. This effect was more prominent for some aspects of panic disorder psychopathology than for others and was correlated with the source of the assessment and publication year. This finding has implications both for research design, to address the heterogeneity and diversity in placebo responses, and for clinical practice to ensure optimal quality of care.

Published: January 2022

This research examined the Homework Completion Program in Atlantic County, NJ, where college students and police officers tutored children with homework. Children ( N = 154) reported their impression of police officers and perception of the program. Across 5 years and three program sites, children chose completing homework as the best part about the program and they mostly reported feeling happy when seeing a police officer and finding police officers if they needed help. In summary, the program has shown promise in achieving the goals of preparing children for a college education and building trust between children and police officers.
Daily social media use, social ties, and emotional well-being in later life
Authors: Kim Yijung K. , Fingerman Karen L. 
Published: January 2022

Older American adults are increasingly utilizing communication technologies, but research has seldom explored older adults’ daily social media use and its interface with other “offline” social ties. To explore a complementary and/or compensatory function of social media in later life, this study employed data from the Daily Experiences and Well-Being Study (2016–2017) to examine associations between daily social media use, daily social encounters, social network structure, and daily mood. Community-dwelling older adults ( N = 310; Mage = 73.96) reported on their overall social network structure (diversity in types of social ties and size of network), their daily social encounters in-person and by phone, social media use, and emotional well-being for 5 to 6 days. Multilevel models revealed that daily social media use was associated with daily mood in the context of daily social encounters and the size of the social network. Individuals reported less negative mood on days with more social media use and more in-person encounters. More daily social media use was associated with more positive mood for individuals with a relatively small social network but not for their counterparts with larger social networks. Findings suggest that social media is a distinct form of social resource in later life that may complement the emotional benefits of daily social encounters and compensate for the age-related reduction in social network size. Future research should consider how socially isolated older adults might use computer-mediated communication such as social media to foster a sense of social connection.

Objective Primary mediastinal B-cell lymphoma (PMBCL) lacks standard treatment regimens. This study aimed to identify the disease’s clinical features and prognostic factors. Methods This retrospective study included 56 patients with PMBCL. Patient demographic details and clinicopathological characteristics were summarized, and their effects on progression-free survival (PFS) and overall survival (OS) were analyzed. Results The median patient age was 29 years (range, 14–56). Twenty-two patients received DA-EPOCH-R (dose-adjusted etoposide, vincristine, and doxorubicin for 96 hours with bolus doses of cyclophosphamide and oral prednisone, as well as rituximab), and 34 patients received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). Clinical/laboratory parameters, overall response rates, and 5-year PFS and OS rates did not differ between the treatment groups. Kaplan–Meier analysis indicated that late-stage disease and a higher International Prognostic Index (IPI) were associated with shorter PFS and OS. Furthermore, patients with B symptoms and first-line treatment non-responders exhibited worse OS. 18Fluorodeoxyglucose-positron emission tomography/computed tomography quantitative parameters, such as higher metabolic tumor volume (MTV) and total lesion glycolysis (TLG), were corrected with shorter PFS. Conclusions This study revealed that stage IV disease, higher IPI, and B symptoms were poor prognostic factors in patients with PMBCL. Significantly, higher MTV and TLG portended worse PFS.

To cope with the stress of lockdown, it was important for people to indulge in educational and health activities to save them from the threats being caused by the news and social media. Summary: A Facebook page named Yoga scholars Post Graduate Institute of Medical Education and Research (PGIMER) was created where three sessions were held per day for 225 days regularly. This activity resulted in people adopting an integrative approach towards alternative medicine. Key message: This also made possible a trial of Ashwagandha for COVID-19 treatment by the Ayurveda, Yoga, Naturopathy, Unani, Siddha and Homeopathy (AYUSH) ministry.
Teaching Gerontology in Transcultural Academics: A Phenomenographic Study of Thai and Swedish Nurse Educators’ Conceptions of Gerontological Nursing
Authors: Mattsson Karin , Rosendahl Sirpa 
Published: January 2022

Introduction: There is an urgent need for registered nurses with gerontological competence within long-term care (LTC) of older adults. Despite increases of life expectancy, LTC for older adults is not emphasized in nursing curricula in neither Sweden nor Thailand. Thus, the aim was to explore conceptions on gerontological nursing (GN) among Swedish and Thai nurse educators. Method: A qualitative phenomenographic method, based on open-ended interviews with five Thai and nine Swedish nurse educators was conducted. Results: The results indicate a paradox between the educators’ knowledge about the implications of global aging, their hope of own aging, and LTC. The ethical responsibility of being credible and a source of inspiration in teaching about aging are focused, while GN seem to be less important. Discussion: To increase students’ interest in GN, measures need to be taken within the educational arenas, where the educators’ own conceptions toward GN, cultural aspects of aging, and LTC are discussed.
