THE ROLE AND PLACE OF DAMAGE CONTROL SURGERY IN MILITARY MEDICAL EVACUATION DOCTRINE DURING HOSTILITIES IN MODERN WAR

Introduction: The severity of the combined injury, traumatic shock, blood loss and traumatic prolonged primary surgery are the cause of high mortality injured patients. In civilian medicine, damage control technology is widely used to treat patients with severe polytrauma, which has improved the survival of this group of patients. Objective: Analyze the effectiveness of using "damage control" technology in wounded with polytrauma at the second level of medical care during war conflict in Eastern Ukraine and organization of combat casualty care. Methods: Medical and statistical analysis of the effectiveness medical treatment for patients combat-ralated injuried and polytrauma performed on the basis of a mobile military hospital during 2015-2019 period. Results: In 660 patients with combat multiple and combined injuries and in 1027 - with severe military combined trauma, medical tratment was provide by "damage control" technology. The main task of the first stage of surgery intervention was to stop the bleeding and stabilize the patient condition. 130 patients with intra-abdominal bleeding underwent laparotomy, temporary stop of bleeding, blood sampling for autotransfusion and temporary closure of the abdominal cavity. For the purpose of temporary hemostasis in 15 patients abdominal tamponade was performed, in 26 - liver tamponade, in 24 - splenectomy, in 6 - nephrectomy and in 6 - put the clamps were applied to bleeding vessels. In 14% injured patients definitive stage of surgical procedures were performed at the second level of medical care on the background of abdominal compartment syndrome in 10, visceral edema in 14 and peritonitis in 40 patients. Conclusions: Providing emergency medical treatment, surgical procedures and intensive care at the second level of medical tretment using the technology of "damage control" and timely patients evacuation are the key to reducing mortality and complications of military surgical trauma

Teachers’ Perceptions of the Transition from Onsite to Online Teaching during the Covid-19 Pandemic

Educational systems worldwide have been affected by government restrictions imposed in response to the Covid-19 pandemic, causing the temporary closure of many educational institutions. The new condition has forced teachers to make the transition from onsite to online teaching. The current study used a descriptive method to examine online teachers’ perceptions towards online teaching during the transition to online learning at a center for foreign languages in Vietnam. The results reveal that teachers have a relatively positive perception of online teaching, although many typical problems of online teaching do present themselves and the effectiveness of online teaching does not always compare favorably with traditional classroom teaching. Teachers’ suggestions are significant for improving online teaching quality. Online teaching is highly likely here to stay and will continue to improve. The transition from traditional face-to-face classrooms to online teaching can be successfully achieved and its quality can be ensured if challenges and ways of improving online learning continue to be closely examined.

Changing Family Relationships During the COVID-19 Pandemic: The Case of Elder Abuse

Since the first confirmed case being identified in January 2020, authorities in Hong Kong have implemented various measures in an attempt to control the spread of the disease. These measures include compulsory quarantining of infected persons and those suspected of exposure, temporary closure of high-risk premises, and suspension of public activities and services, encouraging work-from-home arrangement etc. These measures, however, may exacerbate the impact of known risk factors and create new avenues for elder mistreatment. Life stress, financial strains and work-from-home arrangements increase chances of family conflicts, cessation of public services increases burden in the already stressed caregivers. This study examines the changing intergenerational family relations in the midst of the pandemic. A total of 1200 community dwelling senior citizens participated through responding to a telephone survey. Information was collected on participants’ demographic characteristics, perceived disruptions brought about by COVID-19, family relations, physical and mental health, etc. Family conflicts and abuse were commonly reported: 27.8% reported family conflicts, 14.5% psychological abuse, 3.1% physical abuse, 3.9% financial abuse. A large proportion of participants (41.8%), however, also reported improved family relations during the pandemic. Results of logistic regression indicate that advanced age, female gender, poor financial situation were significant predictors for family conflicts and abuse. Contrary to our expectations, pandemic related disruptions in daily lives and perceived safety in the community were not associated in family conflicts and abuse in the present sample.

The impact of chronic mild hypoxia on cerebrovascular remodelling; uncoupling of angiogenesis and vascular breakdown

Background Chronic mild hypoxia (CMH, 8% O2) stimulates robust vascular remodelling in the brain, but it also triggers transient vascular disruption. This raises the fundamental question: is the vascular leak an unwanted side-effect of angiogenic remodelling or is it a pathological response, unrelated to endothelial proliferation, in which declining oxygen levels trigger endothelial dysfunction? Methods To answer this question, mice were exposed to CMH (8% O2) for periods up to 14 days, after which, brain tissue was examined by immunofluorescence (IF) to determine which type of blood vessel (arteriole, capillary or venule) was most commonly associated with endothelial proliferation and vascular leak and how this correlated with tight junction protein expression. Vascular perfusion was examined using DiI. Data were analysed using one-way analysis of variance (ANOVA) followed by Tukey’s multiple comparison post-hoc test. Results The following was observed: (1) most endothelial proliferation and extravascular fibrinogen leak occurred in capillaries and to a lesser degree in venules, (2) much to our surprise, endothelial proliferation and extravascular fibrinogen leak never colocalized, (3) interestingly however, endothelial proliferation was strongly associated with an intravascular fibrinogen staining pattern not seen in stable blood vessels, (4) DiI perfusion studies revealed that angiogenic vessels were adequately perfused, suggesting that fibrinogen retention in angiogenic vessels is not due to temporary closure of the vessel, but more likely because fibrinogen is retained within the vessel wall, (5) bromodeoxyuridine (BrdU) labelling as a means to more permanently label proliferating endothelial cells, confirmed lack of any connection between endothelial proliferation and extravascular fibrinogen leak, while (6) in contrast, proliferating microglia were detected within extravascular leaks. Conclusions Taken together, our findings support the concept that in the short-term, hypoxia-induced endothelial proliferation triggers transient fibrinogen deposition within the walls of angiogenic blood vessels, but no overt vascular leak occurs in these vessels. Importantly, endothelial proliferation and extravascular fibrinogen leaks never co-localize, demonstrating that extravascular leak is not an unwanted side-effect of angiogenic endothelial proliferation, but rather a dysfunctional vascular response to hypoxia that occurs in a distinct group of non-angiogenic blood vessels.

Emergency Law Responses and the Covid-19 Pandemic (Global State of Democracy Thematic Paper 2021)

In response to the Covid-19 pandemic, governments have implemented a variety of extraordinary legal and policy measures to protect lives, mitigate the spread of the virus, and prevent health systems from breaking down. These measures have often included curbing some human rights, restricting travel, shuttering up classrooms, suspending government services, ordering the temporary closure of businesses, controlling or curtailing news reporting, and sometimes delaying elections. To do this, many governments have activated emergency legal frameworks that provide for the assumption of emergency powers by the executive and, in some cases the weakening or setting aside of ordinary democratic checks and balances. It is helpful to understand the different types of laws relied upon (or not) by governments to justify their assumption of emergency powers and their imposition of emergency measures. This paper examines and compares different types of legal bases for emergency powers, built-in safeguards and constraints specific to each type of emergency regime, the factors that may influence choices about which emergency legal response to apply, and the associated advantages and risks

The company you keep: How network disciplinary diversity enhances the productivity of researchers

The Covid-19 pandemic has affected most organizations' working environment and productivity. Organizations have had to make provision for staff to operate remotely following the implementation of lockdown regulations around the world, because the pandemic has led to restrictions on movement and the temporary closure of workplace premises. The purpose of this paper is to gain a deeper understanding of the effect of this transition on the productivity of work during the pandemic, by studying a distributed network of research who collaborate remotely. We examine how the productivity of researchers is affected by the distributed collaborative networks in which they are embedded. Our goal is to understand the effects of brokerage and closure on the researchers’ publication rate, which is interpreted as an indicator of their productivity. We analyze researchers’ communication networks, focusing on structural holes and diversity, and we take into account the personal qualities of the focal researcher such as seniority. We find that disciplinary diversity among researchers' peers' increases the researchers’ productivity, lending support to the brokerage argument. In addition, we find support for two statistical interaction effects. First, structural holes moderate diversity so that researchers with diverse networks are more productive when their networks also have a less redundant structure. Diversity and structural holes, when combined, further researchers’ productivity. Second, seniority moderates diversity; so that senior researchers are more productive than junior researchers in less diverse networks. In more diverse networks, junior researchers perform as well as senior researchers. Social capital and human capital are complementary. We conclude that the benefits of diversity on researchers’ productivity are contingent on the personal qualities of the researchers and on network structure. The brokerage / closure debate needs a more nuanced understanding of causal relationships.

Unfolding Water Quality Status During COVID-19 Lockdown for the Highly Polluted Santiago River in Jalisco, Mexico

The Santiago River is one of Mexico's most polluted waterways and evaluating its surface water quality during the COVID-19 outbreak is critical to assessing the changes and improvements, if any, from the nationwide lockdown (April-May 2020). Hence, the data for 12 water quality parameters from 13 sampling stations during April-May 2020 (lockdown) were compared with the levels for the same period of 2019 (pre-lockdown) and with the same interval of previous eleven-years (2009-2019). The values of BOD (14%), COD (29%), TSS (7%), f. coli (31%), t. coli (14%) and Pb (20%) declined, while pH, EC, turbidity, total nitrogen and As enhanced by 0.3-21% during the lockdown compared to the pre-lockdown period suggesting decrements of organic load in the river due to the temporary closure of industrial and commercial activities. An eleven-year comparison estimated the reduction of pH, TSS, COD, total nitrogen and Pb by 1-38%. The analysis of water quality index estimates showed short-term improvements of river water quality in the lockdown period, compared to pre-lockdown and eleven-year trend as well as indicated very poor quality of the river. The contamination sources identified by factor analysis were mainly related to untreated domestic sewage, industrial wastewaters and agriculture effluents influencing the river water quality. Overall, our findings demonstrated positive responses of COVID-19 imposed lockdown on water quality of the Santiago River during the study period, providing a foundation for the government policy makers to identify the sources of pollution, to better design environmental policies and plans for water quality improvements.

Inovasi Perpustakaan Perguruan Tinggi Muhammadiyah–‘Aisyiyah (PTMA) Menghadapi Pandemi Covid-19: Sebuah Studi Literatur Bunga Rampai

Introduction. The COVID-19 pandemic has had an impact on education systems around the world, including Indonesia. The government carried out temporary closure of public services to reduce the number of additional cases. One of the community services affected is the library as a support for education. As a supporter of education, the perceived impact is the non-utilization of services in the library. Efforts made by the library to continue to provide services are by changing the system and management mechanism in the library. This paper aims to find out the innovations and strategies implemented in several PTMA libraries in the era of the covid-19 pandemic.Methodology. This study uses a literature review to collect data and documentation to support the analysis.Result. The result of this paper is that PTMA library librarians must be able to use facilities or technology to serve the academic community.Conclusion. The COVID-19 pandemic has not only hurt society. The other side of the Covid-19 pandemic is being able to develop competence through online seminars. In addition, the handling of the COVID-19 pandemic, which is gradually improving, has forced libraries to reopen services while still implementing health protocols to suppress the rate of transmission.
