Aim Rectus sheath hematoma (RSH) is a cause of acute abdomen. This study
aimed to evaluate the possible risk factors of RSH to avoid further
development of the acute condition. Material and Methods This
retrospective study evaluated risk factors of RSH and its presentation,
management, and outcomes for patients with RSH confirmed using computed
tomography scan between January 2018 and April 2020. Results Of 61 study
patients, 56 (91.8%) had at least one chronic disease and 80% were
receiving anticoagulation therapy. The RSH size was significantly larger
for patients taking acetylsalicylic acid (ASA) than other
anticoagulants, and an RSH area >1924 mm2 was associated
with increased length of hospital stay. Binary logistic regression
analysis showed that a unit increase in age was associated with an
increase of 1.5-fold in the risk of greater RSH size and that the female
sex was associated with a 45.3-fold risk of increase in the risk of RSH.
Notably, if at least ≥4 units (U) erythrocyte suspension (ES)
replacement is not applied for conservative treatment of RSH, the size
of the RSH may increase by 23.5 times. Conclusion Risk factors of RSH
such as chronic obstructive pulmonary disease, congestive heart failure,
coronary artery disease, atrial fibrillation, asthma, hypertension,
diabetes mellitus, chronic renal failure, previous abdominal surgery,
female sex, older age, anticoagulant drug use, and cancer-related
immunosuppression.

Published: March 2022

Tracheostomy related tracheal tear is a serious complication that may
follows surgical or percutaneous tracheostomy. Pediatric populations
carry higher risk because of the anatomical differences. It needs
immediate diagnosis as may leads to life threatening outcomes such as
pneumothorax, respiratory distress, extensive subcutaneous emphysema and
pneumomediastinum. The best way to diagnose and discover tracheal tear
is by tracheobronchoscopy. If the diagnosis established prompt
management and treatment should be performed. Objective The aim of this
article is to review tracheal tears and to help in their diagnosis and
management with assistance of clinical and radiological findings.
Methods and Materials A literature review of PubMed , ovid Medline and
cochrane collaboration databases was done using the terms pediatric ,
tracheostomy , tracheal tear. Discussion Tracheostomy related tracheal
tear occurs infrequently and less commonly than intubation related
tracheal tear. Mostly it is related to tracheostomy placement, using
cuffed tubes and overinflation of the cuff or the tear directly follows
traumatizing tracheostomy tube introducer insertion. The tear due to
tracheostomy mostly located proximal to carina and distal to insertion
of point of tracheostomy. Symptoms and complications of the tear may
occur intraopertivly or postoperatively(5). Gold standard method for
diagnosis will be established by flexible or rigid tracheobronchoscopy
which helps in determining the site, size, extension of the tear and its
location with respect to the carina that are essential to document.
Imaging studies like CT scan which also helps in establishing the
diagnosis of tear and some of it is complications such as pneumothorax,
pneumonia, pneumomediastinum and mediastinitis. Treatment can be
conservative for small uncomplicated wound in stable patient. For larger
complicated tears and unstable patient surgical treatment is the gold
standard. Conclusion Treatment choices depend on tear site , size,
extension of the tear and the status of the patient. Conservative
management is sufficient for stable patients with small tears . On the
other hand , surgical management is essential for unstable patients and
large complicated wounds.

Objective: Preoperative testing for COVID-19 has become widely
established to avoid inadvertent surgery on patients with COVID-19 and
prevent hospital outbreaks, however, there is limited evidence
underpinning new protocols. We wished to study the effectiveness of
preoperative COVID-19 testing during and after the first wave of the
pandemic in Ireland. Design Prospective cohort study. Setting: 2
university hospitals in the Republic of Ireland. Participants: Patients
undergoing otolaryngology surgery and the otolaryngologists performing
surgery. Main outcome measure: Incidence of COVID-19 within 30 days of
surgery. Results: 173 patients (56% male) were recruited. 123 (71%)
patients “cocooned” for 14 days prior to surgery. All patients
completed a questionnaire prior to hospital admission. 156 patients
(90%) had reverse transcriptase-polymerase chain reaction (RTPCR)
nasopharyngeal swabs, 14 patients (8%) had CT thorax. No cases of
COVID-19 were detected among patients followed up at 30 days. Two
surgeons developed COVID-19 early during the study period not considered
to be related directly to contact within the hospital. Conclusion:
Current pre-operative testing protocols consisting primarily of
questionnaires and RT-PCR resulted in zero cases of COVID reported in
this cohort. It is possible that COVID-19 restrictions and high
proportion of patients cocooning preoperatively were factors in ensuring
a low rate of COVID-19 postoperatively. Ongoing data collection is
required to confirm these findings in the setting of further disease
surges.

Aim: We aim to investigate the endoscopic and CT scan findings of
pediatric patients with Henoch-Schonlein purpura (HSP). Methods: The
endoscopic and CT findings of the patients were observed. Endoscopy was
carried out using the Olympus GIF XQ 230 electronic gastroscope.
Laboratory tests were carried out to investigate the expression of
potential markers in these patients. In total, 4 females and 2 males
were included in this study, with the median age of 7.5 yrs. All the 6
patients underwent endoscopic examination. Results: One showed hyperemia
and erosion in the gastric antrum, together with punctiform hyperemia in
the gastric balloon and bile regurgitation. One showed erosion in the
gastric fundus, body and angle, as well as hyperemia and edema in the
descendant duodenum, together with massive erosion and ulcer. One showed
hyperemia and erosion in the gastric antrum combined with ecchymosis in
the descending part of stomach. One showed ecchymosis in the descendant
duodenum, and a tendency of hemorrhage. One showed massive ecchymosis in
the descendant part and horizontal part of the duodenum. The other one
showed hyperemia in the descendant duodenum. Endoscopic findings of HSP
consisted of mucous hyperemia and edema, together with local erosion and
irregular ulcer. Some patients at the acute stage presented hemorrhagic
spots and capillary hemorrhage, which usually involved the duodenum,
gastric antrum and body. Conclusion: CT findings of the HSP were edema
and thickening in the small intestinal wall, hydrops in the intestinal
cavity and intestinal obstruction.

The impacts of human-driven environmental changes on the stability of
natural grasslands have been assessed by comparing differences between
manipulative warming and grazing plots and reference plots. However,
little is known about whether or how ambient climate regulates the
effects of manipulative treatments. A 36-year observational dataset
shows that there is a nonlinear response of community stability to
ambient climate. Manipulative warming and grazing decrease community
stability with experiment duration through an increase in legume
coverage and/or decrease in species asynchrony, due to exceeding the
threshold of background annual mean air temperature with decreasing
background annual mean air temperature through time during the 10-year
experiment period. Moreover, the temperature sensitivity of community
stability is more sensitive under the ambient treatment than under the
manipulative treatments. Therefore, our study emphasizes the importance
of the context dependency of the response of community stability to
human-driven environmental changes.

Published: March 2022

A predictive understanding of ecological processes requires identifying
the factors that explain variation in the organismal traits that drive
these processes. Integrating evolutionary history and ecology has been
shown to be essential to understand variation in traits that determine
species interactions in community ecology. However, the extent to which
these factors determine traits relevant for ecosystem dynamics (and thus
ecosystem ecology) is poorly understood. Nutrient cycling is essential
for reef ecosystem dynamics, and consumers are critical drivers of this
process. We use a dataset of nine consumer “chemical traits” (e.g.,
body nutrient content and nutrient excretion rates) associated with
nutrient cycling, collected from 1,572 individual coral reef fish (178
species spanning 41 families) in two biogeographic regions, the
Caribbean and Polynesia, to quantify the relative importance of
phylogenetic history and ecological context as a driver of chemical
trait variation on coral reefs. We find: (1) phylogenetic history is a
better predictor of variation in all chemical traits, overwhelming the
influence of ecological factors, (2) phylogenetic conservatism in
chemical traits is greater in the Caribbean than Polynesia, where our
data suggests that ecological forces may have a greater influence on
chemical trait variation, and (3) differences in chemical traits between
regions can be explained by differences in nutrient limitation
associated with our study locations. Our study provides multiple lines
of evidence that phylogenetic conservatism is a critical determinant of
contemporary nutrient dynamics on coral reefs. More broadly our findings
highlight the utility of evolutionary history to improve prediction in
ecosystem ecology.

Authors: wu xiaobin , li yanxi , yu ruogu
Published: March 2022

Abstract: Objective To investigate the efficacy and prognosis of obesity
in the treatment of children with capillary bronchitis. Methods: A
retrospective analysis of the clinical data of 200 children with
capillary bronchitis hospitalized in our hospital from January 2015 to
January 2016 was performed. Results: After nebulization treatment, the
total effective rate was significantly higher in the normal weight group
than in the obese group (93.3% vs 65.5％, p＜0.005, x2=19.77). And the
significantly effective rate was higher in the normal weight group than
in the obese group (53.3% vs 36％, p=0.008, x2=5.76). The children in
the normal weight group had a significantly shorter duration of
coughing, wheezing and croup than those in the obese group, and the
difference was statistically significant (p<0.05). In the
normal weight group, the proportions of recurrent wheezing episodes and
confirmed asthma were significantly lower than those in the obese group,
among which the proportions of wheezing episodes >1,
wheezing episodes >3 and confirmed asthma were
significantly different (p<0.05). The results of univariate
and logistic regression analyses showed that obesity may be a risk
factor for the development of asthma in children with capillary
bronchitis. Conclusion Obesity has a negative impact on the treatment
and prognosis of children with capillary bronchitis and significantly
increases the chance of developing asthma in the future, suggesting a
new direction for the future treatment of capillary bronchitis that
deserves attention.

Published: March 2022

Zn-binding protein was obtained after purification from scallops
(Mizuhopecten yessoensis) using gel permeation and ion-exchange
chromatography. Amino acid determination result shows that the cysteine
of the zinc-binding protein accounts for one third of the total amino
acids, which is a typical feature of metallothionein (MT). The secondary
structure of zinc-binding protein was determined by Fourier Transform
Infrared Spectroscopy (FTIR) and Circular dichroism (CD), the result
shows that the α-helix was 46.55%, the β-sheets was 27.07%, the random
coil was 16.48% and the β-turns was 9.89%. Using a commercial kit to
measure its in vitro antioxidant activity, the result shows that it has
good scavenging ability to 1, 1-diphenyl-2-picrylhydrazyl (DPPH),
Hydroxyl radical (•OH) and reducing ability to ferrous iron ions. In
this study, the extraction and purification of zinc-binding protein can
be prepared in large quantities, which provide a basis for its
industrialization.

West Nile Disease is a zoonotic vector-borne infection involving viral
pathogens, human and animal hosts, vectors and habitats with a complex
transmission cycle. Cooperation among different disciplines has been
promoted by the Italian Public Health Authorities to introduce a robust
surveillance system and an integrated West Nile Virus (WNV) Surveillance
Plan has been in force in Italy since 2016, in order to establish a
medical, veterinary and entomological network. This represents a unique
model in Europe. This study aims to present this “One Health” approach
applied following the first recorded autochthonous case of West Nile
Neuroinvasive Disease (WNND) in Sicily (Southern Italy). Serological and
molecular tests were conducted on the blood, liquor and urine of a
38-year-old man with encephalitis and meningitis: WNND was confirmed by
serological analysis on liquor and serum. Consequently, a veterinary and
entomological surveillance was started. Overall, 160 mosquito catches
were collected from six different sampling sites and 2704 adult
culicides were morphologically identified. Female mosquitoes were
analyzed in pools for WNV RNA detection. Serological and molecular
assays for WNV were carried out in 11 horses, 271 chickens and 2 dogs
sampled in farms around the man’s residence. Collected mosquito species
included Culex pipiens (93.6%), Aedes albopictus (5.25%), Culex
hortensis (0.6%), Culiseta longiareolata (0.55%) and Anopheles
maculipennis s.l. (0.04%). Mosquito pools were negative for WNV nucleic
acid presence. Two dogs (100%) and two horses (18.2%) resulted
positive for WNV-specific IgG antibodies. Since WNND epidemiology is
influenced by several ecological factors and by the presence of several
animal and vector species, the integrated surveillance system was
crucial for understanding whether the virus had circulated/was
circulating in the suburban, urban area and for preventing the spread of
infection.

Published: March 2022

BACKGROUND For ventricular arrhythmias (VAs) originating from the left
ventricular epicardium adjacent to the transitional area from the great
cardiac vein to the anterior interventricular vein (DGCV-AIV), the most
efficient catheter manipulation approach has not been fully elucidated.
OBJECTIVE This study aimed to investigate a more appropriate catheter
manipulation approach for DGCV-AIV VAs. METHODS One hundred twenty-three
consecutive patients with DGCV-AIV VAs were retrospectively analyzed.
All these patients were firstly mapped and ablated by conventional
approach （Non-Swartz sheath support (NS) approach）. When target sites
not been reached, Swartz sheath support (SS) approach was attempted. If
target sites still unreached, the hydrophilic coated guide wire and left
coronary angiographic catheter-guided deep engagement of Swartz sheath
in GCV to support ablation catheter was performed. RESULTS A total of
one hundred three VAs (103/123, 83.74%) were successfully eliminated in
DGCV-AIV. By NS approach, the tip of catheter reached DGCV in 39.84%
VAs (49/123), reached target sites in 35.87% VAs (44/123), and achieved
successful ablation in 30.89% VAs (38/123), which was significantly
lower than by SS approach (88.61% (70/79), 87.34 % (69/79), and
84.81% (67/79), P<0.05). In left anterior oblique (LAO) view,
angle between DGCV and AIV<83° indicated an inaccessible AIV
by catheter tip with a predictive value of 94.5%. Width/height of
coronary venous system>0.69 more favored a SS approach with
a predictive value of 87%. CONCLUSION For RFCA of VAs arising from
DGCV-AIV, the SS approach facilitates the catheter tip achieve target
sites and contributes to a successful ablation.
Sickle cell disease in southwest Virginia: an analysis of morbidity, acute care utilization, and the effects of social determinants of health in a mixed rural/urban medically underserved community
Authors: Nicchitta Mira , Ogunmayowa Oluwatosin , Atkinson Mandy , Baker Charlotte
Published: March 2022

Background: Sickle cell disease (SCD) is a lifelong disease
characterized by both acute and chronic morbid conditions that often
result in acute care utilization. There is limited data on SCD patients
in medically underserved areas of the United States. Methods: We
conducted a retrospective analysis of SCD patients in a mixed
rural/nonrural partially medically underserved area in southwest
Virginia without access to an adult comprehensive sickle cell center to
describe patterns of disease-related morbidities and acute care
utilization, as well as the effects of other comorbid diseases. Results:
Of the 71 patients who met inclusion criteria, the majority (59.1%)
were insured by Medicaid, 15.5% were insured by Medicare, 14.1%
through a commercial insurer, and 11.3% were self-pay. Medicare- and
Medicaid-insured patients utilized acute care services more often than
those insured by other means. Medicare patients had 124% more acute
pain crises than patients insured by other means. Obesity was a risk
factor for direct admission to the hospital. Additionally, admissions
from the ED were 18.3% lower in females than males, despite the average
age of the female cohort being approximately 8 years older than males.
Conclusion: For this patient cohort without access to an adult
comprehensive sickle cell center, public insurance status through
Medicare or Medicaid was associated with more acute care utilization.
Obesity and male sex were identified as risk factors for
hospitalization. Further study of and targeted interventions for SCD
patients in rural and medically underserved communities is warranted.

Deliberative democracy - theory and practice: The case of the Belgrade citizens’ assembly
Authors: Jankovic Ivana
Published: March 2022

In this paper, we examine whether it is possible to improve democracy by encouraging ordinary citizens to participate in political decision-making and if participation in deliberative institutions can make citizens more competent decision-makers. By using qualitative data, we analyze the discussion from the Belgrade citizens? assembly (CA) focused on the topic of expanding the pedestrian zone in the city center. The CA was organized in Serbia for the first time, as part of a research project aimed at promoting and advancing innovative democratic practices in the Western Balkans. The goal was to encourage the involvement of citizens in discussions of public interest. Our hypothesis was that, through the process of participation and deliberation in CA, ordinary citizens can make reasonable and informed choices, increase their knowledge of the issue discussed, and become more motivated to participate in political decision-making on the local level. Our qualitative content analysis suggests that deliberation had a positive impact on participants? knowledge of the chosen topic of the assembly. It also shows that citizens used exhaustive explanations rather than brief statements, could differentiate the good arguments from the bad, and more often appealed to general rather than private interests. Participants in the assembly reported a significant increase in interest in political decision-making that affects their lives, as well as a sense of being informed about politics. Finally, we wanted to draw attention to the challenges and open questions that remain, namely those that concern the impact of a deliberative body on political decision-making in the real world.

We combined three areas of social capital, G2G and the enterprise architecture (EA) which are some of the important areas. Due to the complexity of governments’ responsibilities, using G2G EA is essential. Three EA styles and five elements of G2G are elected and a combination method of scenario planning and interviews is chosen as the research method. Four steps are determined for the scenario planning(SP) process. And, in one of the steps in SP, we create 9 scenarios with three elements of social capital (Trust, Partnership and Norm). Then, by using interviews, we propose eight different combinations of the three styles of EA and five elements of G2G.

Published: March 2022

The fundamental function of a Cellular Manufacturing System (CMS) is based on the definition and recognition of a type of similarity among the parts that must be produced in a planning period. Cell Formation (CF) and cell machine layout design are two important steps in the implementation of the CMS. This paper represents a new mathematical nonlinear programming model for dynamic cell formation that employs the rectilinear distance notion to determine the layout in the continuous space. In the presented model, the objective function accurately calculates the costs of inter and intra-cell movements of parts and calculates the cost of a cell restructure. Due to the problem complexity, the presented mathematical model is categorized in NP-hardness; thus, a Genetic Algorithm (GA) is used for solving this problem. Comparing the results from the GA and the results from solving a linear model through Lingo specifies that solving the presented model accurately for more than four machines in a logical time is impossible.

New strategies in the development of anthrax vaccines and therapeutics have been presented. Recently, considerable progress has been made in the finding of new drugs and suitable therapy for anthrax. Very promising research considers the use of antimicrobials against selected bacteria species, including antibiotic-resistant strains. However, alternative therapeutic options should also be considered, among them vaccines. Bacillus anthracis spores are still the most dangerous weapon amongst pathogens which can be used in a bioterror attack. In this case, research for new anti-anthrax preparations is of primary importance for the protection of humans and animals. The overview of the most recent data shows the many new and promising possibilities for effective strategies in the development of vaccines and anti-anthrax preparations. The most effective of them should be available in the National Stockpile in the event of a biological crisis.
Colifagi Somatyczne jako Wskaźnik w Ocenie Jakości wody do Picia

Streszczenie

Colifagi są wirusami bakteryjnymi, które od wielu lat są przedmiotem badań mających na celu między innymi określenie ich przydatności i zastosowania jako wskaźników zanieczyszczenia kałowego oraz obecności wirusów chorobotwórczych w wodzie. Retrospektywne badania występowania epidemii chorób wodopochodnych wykazały, że opieranie się jedynie na założeniach związanych z brakiem lub obecnością bakterii Escherichia coli, może nie być wystarczające do oceny bezpieczeństwa wody przeznaczonej do spożycia przez ludzi. Colifagi w porównaniu ze wskaźnikami bakteryjnymi, wykazują większą odporność na dezynfekcję i utrzymywanie się w znacznych odległościach od źródła zanieczyszczenia. Ich zastosowanie w celu wzmocnienia kontroli i bezpieczeństwa wody do picia zostało zarekomendowane przez ekspertów WHO i wprowadzone w dyrektywie (UE) 2020/2184. Colifagi somatyczne są nowym wskaźnikiem jakości mikrobiologicznej wody, w tym występowania wirusów jelitowych i mogą służyć do weryfikacji procesów uzdatniania wody i oceny ich skuteczności w usuwaniu chorobotwórczych wirusów.
Reform of the EU Cohesion Policy in the Context of the New 2021-2027 Multiannual Financial Framework: A Study on the Post-2020 Prospects of Central and Eastern European Interdependence
Authors: PETRE Bianca-Georgiana
Published: March 2022

In the midst of competing demands triggered by historical decisions and novel challenges of the 21st century, the EU’s long-term budget is once again expected to capitalize on its finite resources in the most efficient manner. In the context of the 2021-2027 Multiannual Financial Framework (MFF), which has been situated at the heart of a long-standing debate on “the future of Europe”, this research study investigates the impact of the reform of the EU Cohesion Policy on the ongoing process of EU integration of six Member States in Central and Eastern Europe (CEE), in terms of their expected fragmentation or interdependence. This main research objective is complemented by a secondary ambition of assessing whether this EU investment instrument will facilitate their digital transformation in the post-2020 programming period. Thus, this paper challenges the reader with a change of perspective from the traditionally scrutinized East-West divide to the potential internal divisions within CEE-6, a subgroup of the Friends of Cohesion. By means of a case study, the analysis unveils a disintegration tendency, given the different country-specific positions towards the EU values and their respective national interests, which are expected to complicate the Member States’ compliance with the revised regulatory framework of the Cohesion Policy. As for their digital transformation, the future Regional Policy appears to be a step forward in the right direction, due to a higher thematic concentration on innovation. The research study concludes with a series of three policy recommendations, in view of preventing the evolution of the remarked fragmentation trend.
