Structural Monoclinicity and Its Coupling to Layered Magnetism in Few-Layer CrI3.

Using polarization-resolved Raman spectroscopy, we investigate layer number, temperature, and magnetic field dependence of Raman spectra in one- to four-layer CrI3. Layer-number-dependent Raman spectra show that in the paramagnetic phase a doubly degenerated Eg mode of monolayer CrI3 splits into one Ag and one Bg mode in N-layer (N > 1) CrI3 due to the monoclinic stacking. Their energy separation increases in thicker samples until an eventual saturation. Temperature-dependent measurements further show that the split modes tend to merge upon cooling but remain separated until 10 K, indicating a failed attempt of the monoclinic-to-rhombohedral structural phase transition that is present in the bulk crystal. Magnetic-field-dependent measurements reveal an additional monoclinic distortion across the magnetic-field-induced layered antiferromagnetism-to-ferromagnetism phase transition. We propose a structural change that consists of both a lateral sliding toward the rhombohedral stacking and a decrease in the interlayer distance to explain our experimental observations.

Gender differences and trends of attitude toward smoking and diet behavior in population aged 25-64 years from 1988 to 2017

The aim: To determine gender differences in the dynamic of attitude toward smoking and diet behavior in an open population of 25-64 years over a long-term period - 29 years in Russia / Siberia (Novosibirsk). Methods: Within the framework of the screening in 1988-89 under the WHO MONICA-psychosocial (MOPSY) program (n=1676, 49.5% males, mean age 44.1±0.4 years), MOPSY screening in 1994-95 (n=1527, 43% males, mean age 44.85 ± 0.4 years), in 2003-2005 under the international project HAPIEE (n=1650, 34.9% males, mean age 54.25±0.2 years), in 2013-2016 (n=975, 43.8% males, mean age 34.5±0,4 years) and 2016-2017 (n=663, 41.3% years 51.95±0.32 years) within the framework of the budgetary theme No. AAAA-A17-117112850280-2, random representative samples of men and women in one of districts in Novosibirsk were examined. Smoking status and diet behavior assessed by questionnaire proposed by MONICA-MOPSY protocol. Results: The proportion of men who ever smoked was extremely high (80%) in the general population of 25-64 years and remained unchanged in the period 1988-2003 but began to decrease in 2013, first in the younger age groups and in 2016- 2017 in the older age groups. Despite the fact that there are significantly fewer female smokers, the proportion of female smokers began to increase in 1994, firstly in younger age groups and by 2003-05 in older age groups. Men of younger age groups more often than women tried unsuccessfully to give up a harmful habit. But in 2013-2016, the proportion of those who quit smoking increased to 25-29%. Men were 1.5-2 times more likely than women to report that they did not need to follow a diet. The number of those adhering to the diet, despite the increase in 2013-17, on average did not exceed 10% during 29 years of observation. Diet men were absent in the younger age group in 1988; but in the 45-54 age group their number reached a maximum of 17.1% in 2016-17, overtaking women in this indicator. The proportion of unsuccessful dietary attempts was higher among women in all age groups. The gender gap in the frequency of failed attempts to follow a diet has been growing since 2003. And in 2013-16, more than half of the male and 2/3 of the female population were unsuccessful in trying to adhere to the diet. Conclusions: There was a trend towards a decrease in smoking among men and, at the same time, a decrease in the proportion of women who never smoked in the period from 1994 to 2017. More than half of the male population and 2/3 of the female population were unsuccessful in trying to adhere to the diet, so the proportion of those following the diet did not exceed 10% during 29 years of observation.

Distal Pancreatic Resection with Splenectomy in the Rat: A Pancreatic Fistula Model to Investigate Postsurgical Damage?

Background: Postoperative pancreatic fistula (POPF) is a major complication in pancreatic surgery and can cause considerable postoperative morbidity. Advanced surgical-technical approaches to prevent POPF did not yield a substantial improvement. To investigate innovative treatments, experimental animal models of distal pancreatic resection and pancreaticoduodenectomy are of fundamental importance. After a failed attempt to replicate a previously described rat model for pancreatic fistula induction, we proceeded to distal pancreatic resection with splenectomy to provoke pancreatic leakage and generate a suitable animal model. Methods: Distal pancreatic resection with splenectomy was performed in 40 rats. The rats were sacrificed on postoperative day (POD) 1, 2, 4, 6, 8, or 10, and the abdominal cavity was explored. Ascites probes were collected pre- and postoperatively for the detection of pancreas amylase and lipase. Tissue samples from the naïve pancreas (POD 0) and the postoperatively harvested remnant were evaluated histologically. The extent of necrosis was determined, and samples were examined for neutrophil infiltration. TUNEL staining served for the verification of necrosis in distinct cases. Immunohistochemistry of Ki67, von Willebrand factor, and CD68 was performed to evaluate proliferation, blood-vessel sprouting, and macrophage invasion. Results: The rats showed no clinical symptoms or severe complications in the postoperative course up to 10 days. Abdominal exploration revealed adhesions in the upper abdomen, but no intra-abdominal fluid accumulations were found. Signs of inflammation and tissue damage were evident at the pancreatic resection margin on histological examination whereas the naïve pancreatic tissue was widely unaffected. Statistically significant differences were seen between the preoperative and postoperative extent of necrosis, the presence of neutrophil infiltrate, and levels of ascitic amylase and lipase. Immunohistochemical staining on Ki67, von Willebrand factor, and CD68 did not reveal any workable results on nonstatistical examination, and it was therefore not considered for further analyses. Conclusion: Creating a functional animal model of pancreatic fistula that reflects the clinical and pathophysiological impact of pancreatic leakage in humans has not been achieved. Our approach of left pancreatic resection recapitulated inflammation and tissue damage, early events in the development of fistulas, and it could be suitable for the experimental testing of novel targeting methods.

The meanings of differentiated instruction in the narratives of Eritrean teachers

ABSTRACT The principles of inclusive education largely accepted by governments of different countries require differentiated classroom instruction to meet the diverse needs of individual students. Despite this, teachers have differing experiences and understandings about implementing differentiated instruction (DI) and heterogeneous classrooms. This narrative study aimed at exploring the meanings of DI in the Eritrean context, where teachers are not explicitly familiar with the concept, although their teaching practices reflect some level of differentiation. The research data consisted of 17 narrative interviews with Eritrean mathematics and science teachers. The results of the narrative analysis showed that the teachers constructed five meanings of DI in their narratives: as a caring orientation, as a flexible pedagogic approach, as a self-reflective process, as a failed attempt and as a demanding approach. The majority of the narratives were found to produce positive meanings of DI, and the teachers constructed strong agency towards carrying out DI. These examples of sophisticated DI practices in the teachers’ positive narratives could be utilised to implement DI, even in situations where teachers have limited resources and training and in contexts with large class sizes.

Double Trouble: A Challenging Case of Synchronous Catecholamine-Secreting Neck Paraganglioma and Pheochromocytoma

Abstract Background: Sympathetic paragangliomas (PGL) are regarded as catecholamine-secreting, extra-adrenal counterparts of pheochromocytomas (PCC). Hormone producing head and neck PGL (HNPGL) are exceedingly rare, as most HNPGL are biochemically silent parasympathetic tumors. Here, we present a case of synchronous sympathetic cervical PGL and PCC. Clinical Case: A 47-year-old male was referred to the Neuroendocrine Tumor Unit clinic after a failed attempt at PGL removal at another center. The patient had a 10-year history of hypertension and a family history of his mother’s sudden death. Prior to referral, he presented with a palpable 6 cm right neck mass - an uneventful core-needle biopsy pathology revealed PGL. Subsequent workup showed profoundly elevated plasma metanephrine (MN) 3000 pg/ml [<65] and normetanephrine (NMN) 3500 pg/ml [<196]. Following a week of 2 mg/d doxazosin therapy, an attempt to operate on the patient for PGL was aborted after the skin incision over the mass due to an intraoperative hypertensive crisis. Upon arrival to our unit, reassessment disclosed a sustained stage 3 hypertension that required a four antihypertensive drug regimen with doxazosin dose titration up to 16 mg/d. MRI showed a 6 cm well-defined mass that displaced the common carotid artery and internal jugular vein (IJV) anteromedially, consistent with a PGL of sympathetic chain origin. MRA identified no tumor feeding vessels that could be suitable for embolization. Ga68 DOTATATE PET/CT showed a single focus of radiotracer uptake in the right neck PGL; however, the CT did image a 1.3 cm right adrenal mass with radiographic features suggestive of PCC. The patient underwent surgery for the PGL, using vigilant intraoperative hemodynamic and upper cranial nerve monitoring. An extreme hypertensive episode (systolic BP 340 mmHg) early on during the tumor’s dissection was resolved once the venous connection between the PGL and the IJV was divided. Pathology revealed a 6 cm PGL with free surgical margins. Postoperatively, hormone levels dropped significantly (MN 98 pg/ml [<65]; NMT 198 pg/ml [<196]). Subsequently, right adrenalectomy was performed, confirming the diagnosis of a 1.6 cm PCC. At the last follow-up, the patient’s hypertension was controlled on 5 mg/d amlodipine. Plasma MN and NMN levels were normal. Genetic analysis for PGL/PCC-associated genes revealed no germline mutation. Conclusion: This case highlights the importance of preoperative workup and perioperative management of large PGL. Head and neck PGL resection may be challenging depending on tumor size and location. Early division of the venous outflow from the PGL into the IJV plays a crucial role in intraoperative hemodynamic control. A multidisciplinary team at experienced centers must be involved in every aspect of the patient’s care to achieve optimal results.

Hybrid Retransmissions of Bundle Protocol for Reliable Deep-Space Vehicle Communications in Presence of Link Disruption

Targeted as the main protocol of delay/disruption-tolerant networking (DTN) for space, bundle protocol (BP) is intended to establish an overlay network for reliable file delivery in a heterogeneous networking environment. Reliable data transmission mechanisms of BP are presently under development. In this paper, a new transmission approach is proposed for BP for highly reliable data delivery in deep-space vehicle communications in presence of an unpredictable or random link disruption. The main idea of the proposed approach is to use a hybrid of proactive retransmission and reactive retransmission mechanisms during file transfer. Analytical models are built in various transmission cases to study the effect of link disruption on reliable transmission of BP, with focus on the number of failed transmission attempts, file delivery time and goodput performance normalized with respect to the total amount of data sent. The models are validated by the file transfer experiment over a PC-based testbed. A performance comparison between the proposed approach and the existing transmission approach with respect to transmission reliability is also presented.

Successful Surgical Removal of Firmly Impacted Pancreatic Duct Stent: Two Case Report

Successful surgical removal of firmly impacted pancreatic duct stent: Two case report Recently, the self-expandable metallic and plastic stents are increasingly being used for management of different pancreatic disorders. The major indications for pancreatic stent placement are: pancreatic duct stones, chronic pancreatitis, pancreatic strictures, unresectable pancreatic cancer, preventing POPF and post-ERCP pancreatitis, papillary adenoma. Stent placement or retrieval and exchange is difficult process and sometimes it could be the serious clinical challenge. We report two cases of successful removal of firmly impacted pancreatic duct stent by open surgical intervention and transduodenal approach with lateral “side-to-side” pancreaticojejunostomy to prevent the risk of main pancreatic duct restenosis in the first case and with the sphincteroplasty in the second. Therefore, in these challenging cases of firmly impacted pancreatic duct stents, our choice seems to be the most optimal and effective surgical procedure, which could be considered like “parachute” option after failed attempts of stents removal by endoscopic and radiological procedures.

Interval estimation, point estimation, and null hypothesis significance testing calibrated by an estimated posterior probability of the null hypothesis

Much of the blame for failed attempts to replicate reports of scientific findings has been placed on ubiquitous and persistent misinterpretations of the p value. An increasingly popular solution is to transform a two-sided p value to a lower bound on a Bayes factor. Another solution is to interpret a one-sided p value as an approximate posterior probability. Combining the two solutions results in confidence intervals that are calibrated by an estimate of the posterior probability that the null hypothesis is true. The combination also provides a point estimate that is covered by the calibrated confidence interval at every level of confidence. Finally, the combination of solutions generates a two-sided p value that is calibrated by the estimate of the posterior probability of the null hypothesis. In the special case of a 50% prior probability of the null hypothesis and a simple lower bound on the Bayes factor, the calibrated two-sided p value is about (1 – abs(2.7 p ln p)) p + 2 abs(2.7 p ln p) for small p. The calibrations of confidence intervals, point estimates, and p values are proposed in an empirical Bayes framework without requiring multiple comparisons.

Uniform labelled calculi for preferential conditional logics based on neighbourhood semantics

Abstract The preferential conditional logic $ \mathbb{PCL} $, introduced by Burgess, and its extensions are studied. First, a natural semantics based on neighbourhood models, which generalizes Lewis’ sphere models for counterfactual logics, is proposed. Soundness and completeness of $ \mathbb{PCL} $ and its extensions with respect to this class of models are proved directly. Labelled sequent calculi for all logics of the family are then introduced. The calculi are modular and have standard proof-theoretical properties, the most important of which is admissibility of cut that entails a syntactic proof of completeness of the calculi. By adopting a general strategy, root-first proof search terminates, thereby providing a decision procedure for $ \mathbb{PCL} $ and its extensions. Finally, semantic completeness of the calculi is established: from a finite branch in a failed proof attempt it is possible to extract a finite countermodel of the root sequent. The latter result gives a constructive proof of the finite model property of all the logics considered.

How Evidence-Based is Evidence-Biased Medicine

No chemical imbalances have been proven to exist in relation to any mental health condition, like serotonin deficiency in synapses in the socalled depressive disorders or dopamine imbalance and dopamine receptors distribution in so-called schizophrenia. No independent objective biological marker or current brain imagining science like fMRI exist to date in support of any psychiatric diagnosis, and finally yet importantly, no biological causes exist for any of the so-called psychiatric disorders. If we avoid Cartesian dualism, the claim that mental disorders are biological is obviously a tautology. Given the facts above, psychiatric diagnostic manuals, such as the DSM and ICD, are school examples of what evidence-based science is not and represent nothing but a failed attempt to build a legal road from Health Care to Hell Care by over-medicalization and by the suffering of human and non-human animals. Furthermore, psychiatric drugs can have long-lasting effects on the brain and the central nervous system, while the withdrawal from them can cause a range of severe physical and psychological effects.

Localisation or deglobalisation? East Asia and the dismantling of liberal humanitarianism

Among the 2016 World Humanitarian Summit outcomes, localisation of humanitarian aid has received the greatest amount of attention. Localisation is described as giving more support to national first respondents, making humanitarian aid ‘as local as possible, as international as necessary’. Despite the good intentions, localisation presents a biased understanding of the local and its agency in transforming humanitarianism. Not only is localisation a failed attempt to reconfigure the international humanitarian system power relations, dominated by Western actors, but also it glosses over the crucial role of the South in moulding the humanitarian action norm. In order to address the latter, the paper reviews the history of humanitarian action in East Asia as a case of norm circulation, showing how the region’s agency was essential to accommodate the foundations of liberal humanitarianism during the Cold War and, in the last two decades, to contest them. I argue that instead of localisation, a process of deglobalisation is taking shape in the region, based on increased national ownership of crisis response, privileging reciprocal, bilateral support over multilateral action, and legitimating the rejection of unnecessary support. These changes are pushing traditional humanitarian actors to rethink their practices, bringing much-needed change but also challenges.

Culture, Institutions and Financial Development

When culture and institutions coevolve, which means that these are changing simultaneously and in the same direction, financial development is facilitated. In contrast, when institutions and the cultural background deviate from this development, their asynchronous and different direction changes may lead to a series of failed attempts to implement a modernized financial development framework. Thus, the purpose of the paper is to highlight whether the institutional and cultural backgrounds operate in a complementary or substitute way in terms of their role in financial development. An unbalanced panel dataset comprising 98 countries over the last four decades (1981–2019) is used. The empirical results indicate that both the institutional background and the cultural background positively affect financial development. Furthermore, there is a complementary relationship between the institutional background and the cultural background in terms of their role in financial development; when both sizes are at a strong level, this leads to the highest level of financial development, while when at least one or both are at a weak level, the financial development is lower. Moreover, the interaction term of the two sizes has a positive and statistically significant effect on financial development in all tests performed. Lastly, the institutional background seems to have a greater impact on the formation of the level of financial development in relation to the cultural background. To upgrade the financial development of their economies, policymakers have to realize economic policies that change the institutional background and simultaneously change the cultural background in the same direction.

A122 WATER EXCHANGE FACILITATES HIGH CECAL INTUBATION RATE FOLLOWING INCOMPLETE COLONOSCOPY

Abstract Background Incomplete colonoscopy is a complex problem that negatively affects the success of colon cancer screening programs. Failure to intubate the cecum is associated with a significant risk of missed colorectal cancer and increases costs through missed diagnoses and salvage investigations. Water exchange (WE) colonoscopy is associated with a high rate of patient comfort and cecal intubation (CI) and may be of value in preventing and following up on incomplete colonoscopy. Aims To estimate effectiveness of WE colonoscopy as initial salvage of incomplete colonoscopy. Methods All patients referred to the Kelowna Gastroenterology group for incomplete colonoscopy between Jan 2010 to Dec 2019 were included. Demographic, clinical, procedural, and pathological information were collected via retrospective chart review. Patients underwent WE colonoscopy by a single endoscopist. The outcomes evaluated were CI rate, sedation requirements, and adenoma detection. Results 116 patients met study criteria and underwent WE colonoscopy after a previously failed or incomplete colonoscopy for technical reasons. The mean age was 66 years (range 21–89). 83 (72%) patients were female. 53 (46%) patients had previous abdominal surgery, and 42 (36%) had previous pelvic surgery. 65 (56%) patients had previous bowel disease. 81 (70%) patients had previously incomplete conventional air insufflation (AI) colonoscopy, 9 (8%) patients had previously incomplete WE colonoscopy, and 5 (4%) patients underwent unsuccessful combination of WE and AI colonoscopy. 17 (15%) patients had previously incomplete flexible sigmoidoscopy, and 4 (3%) patients had previously incomplete water immersion colonoscopy. The most common cause of unsuccessful CI was redundant colon (n=39, 34%) followed by strictures/angulations (n=16, 14%). 105 (91%) patients underwent repeat WE colonoscopy only, while 7 (6%) patients had combination WE and AI colonoscopy and 4 (3%) patients had concurrent gastroscopy. CI was successful in 114 (98%) patients and unsuccessful in 2 (2%) patients. 87 (75%) study patients received conscious sedation, 16 (14%) opted for no sedation, and 7 (6%) attempted no sedation then switched to conscious sedation. 5 patients (4%) required general anesthesia. CI was achieved in all 16 unsedated patients. 236 polyps were identified in 79 (68%) patients, 2 (1%) of which were malignant. Conclusions There is no standardized approach to incomplete colonoscopy. In this cohort of patients with previous failed attempt at colonoscopy, WE as a primary technique was associated with a high success rate with minimal need for general anesthesia and a high rate of polyp detection. A significant rate of colon cancer was identified, similar to that seen in general screening populations. Funding Agencies None

THE CORRELATION BETWEEN THE RIGHT TO DEATH AND THE RIGHT TO DIGNIFIED DEATH

In order to examine the object of research, and both to achieve the goal of research and to ensure the completeness, objectivity, reliability and persuasiveness of the results, the author used a set of general and special methods that are peculiar to legal science. In particular, the origin and long historical path of development of certain human rights were studied with the help of the historical method. On the basis of system-structural method there has been formulated the general structure of the study; with the help of dialectical method the author has analyzed the provisions of law and case law on the pecularities of the right to die. The analysis of the legislation of foreign countries has been provided using comparative legal method, which have made it possible to recall their positive experience in terms of analysis of the right to death.
 This article reveals the scientific approaches of researchers to determine the nature of death, the right to die, the right to a dignified death, to identify features thereof and to provide distinction between them. The paper analyzes ways to protect the right to die. Part of the work is devoted to the analysis of the law enforcement practice of the European Court of Human Rights on the possibility and expediency of the existence of certain criteria for restricting the right to life.
 Based on the study, it has been concluded that death and the right to die, the right to die and the right to a dignified death are correlated as primary and secondary, i.e., the right to die includes all these concepts. They cannot exist without each other. In different countries they are interpreted differently, but the main feature thereof is the free will of a person, who has an incurable disease, to die. It has been argued that the term right to a dignified death is the most appropriate to use. It has been noted that a significant number of foreign countries provide for the right to die and euthanasia.

Association between the number of pulls and adverse neonatal/maternal outcomes in vacuum-assisted delivery.

To determine the association between the number of pulls during vacuum-assisted deliver and neonatal and maternal complications. This was a single-center observational study using a cohort of pregnancies who underwent vacuum-assisted delivery from 2013 to 2020. We excluded pregnancies transitioning to cesarean section after a failed attempt at vacuum-assisted delivery. The number of pulls to deliver the neonate was categorized into 1, 2, 3, and≥4 pulls. We used logistic regression models to investigate the association between the number of pulls and neonatal intensive care unit (NICU) admission and maternal composite outcome (severe perineal laceration, cervical laceration, transfusion, and postpartum hemorrhage≥500mL). We extracted 480 vacuum-assisted deliveries among 7,321 vaginal deliveries. The proportion of pregnancies receiving 1, 2, 3, or≥4 pulls were 51.9, 28.3, 10.8, and 9.0%, respectively. The crude prevalence of NICU admission with 1, 2, 3, and≥4 pulls were 10.8, 16.2, 15.4, and 27.9%, respectively. The prevalence of NICU admission, amount of postpartum hemorrhage, and postpartum hemorrhage≥500mL were significantly different between the four groups. Multivariable logistic regression analysis found the prevalence of NICU admission in the≥4 pulls group was significantly higher compared with the 1 pull group (adjusted odds ratio, 3.3; 95% confidence interval, 1.4-7.8). In contrast, maternal complications were not significantly associated with the number of pulls. Vacuum-assisted delivery with four or more pulls was significantly associated with an increased risk of NICU admission. However, the number of pulls was not associated with maternal complications.

Analyzing Failed Institutional Change Attempts

Theoretical advances in the study of institutional change center around a productive paradox. While change agents can take strategic action to change institutions, institutions display a remarkable level of formal stability. From this paradox, we expect that attempts to change institutions are an empirical regularity and that many formal change attempts will fail. This article contributes to historical institutionalism by analyzing the political effects of failed formal institutional change attempts on institutional sequences. Failed institutional change attempts could be mere blips, having little effect on subsequent institutional trajectories, or even inoculate against future attempts. Failed attempts could also lay the ideational groundwork, aid in coalition building, and garner concessions for subsequent institutional change, or convince change agents to alter their strategy. The article suggests analytical strategies to assess the effects of failed institutional change attempts, drawing on examples from comparative politics and two extended case illustrations from Italian party politics and the Affordable Care Act in the United States.

The importance of videolaryngoscopy in maxillofacial practice associated with restricted mouth opening in traumatized patients

Orotracheal intubation is considered the most delicate maneuver performed by anesthesiologists, and failure to manage the airways is one of the main causes of possible complications that can be catastrophic during its performance, thus requiring good team planning. Anatomical and / or physiological characteristics, such as limited mouth opening, a condition often found in patients suffering from fractures of the zygomatic arch or who have some abnormality in the temporomandibular joint (TMJ), can characterize a difficult airway, which demands attention greatest of the professional. Therefore, in order to overcome the obstacles that may occur during a difficult or unexpected intubation, new tools have been used, such as videolaryngoscopy in which an intubation device containing miniature video cameras is used in order to allow the operator has an indirect view of the glottis to increase success rates and decrease intubation time. The aim of the present study is to report a clinical case of a trauma victim, with limited mouth opening, who underwent intubation with the aid of a video laryngoscope after failed attempts at conventional intubation.
