Wild collection of medicinal and aromatic plants (MAPs) for commercial purposes in Poland - a system’s analysis
Authors: Sucholas Joanna , Ukhanova Mariya , Greinwald Anja , Luick Rainer 
Published: November 2021

Summary

Introduction: Poland is one of the main exporters of medicinal and aromatic plants (MAPs) in Europe. A substantial part of this plant material is collected in the wild. So far, the system of wild collection (WC) of medicinal plants in Poland, its social and ecological aspects have not been studied comprehensively.

Objective: The aim of the study was to analyse the organisation of WC system in Poland, including legislation, situation of protected species, and socio-ecological dimensions of the MAPs’ supply chains.

Methods: Data from environmental agencies (RDOŚ) about protected MAPs was analysed. Stakeholders engaged in WC were interviewed. National legislation on WC was reviewed.

Results: Although Poland is the second largest exporter of MAPs in Europe, legislation on wild collection in the country is sparse and incoherent. Monitoring does not apply to WC entirely. The structure of WC has a large degree of informality, lacks transparency, and does not take many sustainability criteria into account.

Conclusions: The system needs major adjustments: a) to insure sustainability of WC, b) to accommodate market demands, including plant material quality.

Authors: Quoc Le Pham Tan 
Published: November 2021

Summary

Introduction: Coffee bee pollen contains some precious bioactive compounds, especially phenolic compounds. This material is easily found in many regions in Vietnam and is quite useful for human health.

Objective: The main aim of this study was to determine the best extraction conditions for the total polyphenol content (TPC) and antioxidant capacity (AC) of coffee (Coffea robusta L. Linden) bee pollen with microwave-assisted extraction (MAE).

Methods: TPC and AC of extract of coffee (C. robusta) bee pollen were determined using Folin-Ciocalteu (FC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, respectively. In addition, micromorphology of sample was observed using scanning electron micrographs (SEM).

Results: The findings showed that all factors strongly affected the efficiency of the extraction process. The best extraction conditions obtained were ethanol concentration of 60% (v/v), solid to solvent ratio of 1/30 (w/v), extraction time of 7 min, and a microwave power of 314 W.

Conclusion: The highest TPC and AC obtained were 13.73 mg GAE/g DW and 10.08 µmol TE/g DW with aqueous ethanol as the solvent at the optimal extraction condition. In addition, the microstructures of the material changed insignificantly under microwave irradiation.
Cytoprotective roles of epigallocatechin gallate and resveratrol on staurosporine-treated mesenchymal stem cells in in vitro culture
Authors: Burczak Arkadiusz , Kosiedowska Magdalena , Borkowska Paulina , Kowalski Jan 
Published: November 2021

Summary

Introduction: There are many scientific reports on the beneficial effects of epigallocatechin gallate and resveratrol on the human body, e.g. antioxidant properties, a protective effect on the circulatory system and reduction of inflammation.

Objective: The aim of the study was to evaluate the effect of these substances on the survival of mesenchymal stem cells (MSC) in the presence of the pro-apoptotic factor staurosporine.

Methods: Cell viability WST-1 colorimetric assay.

Results: It was confirmed that both 25 µM/ml and 50 µM/ml of epigallocatechin and 50 µM/ml of resveratrol statistically significantly increased the MSC survival rate.

Conclusion: An excess supply of epigallocatechin gallate (50 µM/ml and higher) has a cytotoxic effect on MSC, which may have a negative impact on the body’s auto-regenerative capacity. Under toxic and stressful conditions, resveratrol and epigallocatechin gallate perform cytoprotective functions, thereby reducing the negative impact of toxic environmental conditions on the mesenchymal stem cells.
Challenges and chances by involving community interpreters in the regular health care of pregnant women and young mothers from third countries with language barriers. A qualitative study within the project RundUm – Transcultural network in the care of pregnancy and birth / Herausforderungen und Chancen bei der Hinzuziehung von Sprach- und Integrationsmittlerinnen in die Regelversorgung von Schwangeren und jungen Müttern aus Drittstaaten.

Abstract

Einleitung
Zur sprachlichen Verständigung und Partizipation an den Versorgungsstrukturen des Sozial- und Gesundheitswesens bei Menschen mit Sprachbarrieren und einem Migrations- oder Fluchthintergrund entwickelte sich der Tätigkeitsbereich der Sprach- und Integrationsmittler/-in in Abgrenzung zum/zur Dolmetscher/-in. Im Rahmen des Forschungsprojektes RundUm begleiteten Sprach- und Integrationsmittlerinnen des Sprachmittlerdienstes SprInt in Essen Schwangere und junge Mütter zu Terminen der Regelversorgung im Gesundheitswesen. Die Chancen und Herausforderungen innerhalb der geburtshilflichen Versorgung aus Sicht der Sprach- und Integrationsmittlerinnen sind Gegenstand der vorliegenden Studie.

Methode
Im Rahmen von qualitativen Experteninterviews wurden 14 Sprach- und Integrationsmittelnde des Sprachmittlerdienstes SprInt in Essen befragt. Die Transkripte wurden inhaltsanalytisch ausgewertet.

Ergebnisse
Herausforderungen zeigen sich in der Kontaktaufnahme zu den Klientinnen und in Aspekten der Zusammenarbeit mit professionellen Fachkräften und dem Verhältnis zwischen professionellen Akteuren/-innen der Regelversorgung und ihren Patientinnen/Frauen. Fehlende sprachliche Kompetenzen der Sprachmittlerin im Themengebiet der geburtshilflichen Versorgung, die Konfrontation mit interkulturellen Unterschieden und eine Unsicherheit der professionellen Akteure/-innen im Umgang mit Sprach- und Integrationsmittlung beeinflussen die Tätigkeit. Daneben bieten unterschiedlich praktizierte Rollenverständnisse der SprInterinnen Chancen und Konfliktpunkte in der Zusammenarbeit im Versorgungsnetzwerk Schwangerer und junger Mütter.

Diskussion
Die Bedeutung der Arbeit der Sprach- und Integrationsmittlerinnen für eine bedarfsgerechte geburtshilfliche Versorgung von Frauen mit Sprachbarrieren bietet Chancen für eine öffentliche Diskussion um die Anerkennung des Tätigkeitsprofils. Anpassung und Ausbau von themenspezifischen Qualifikationsmaßnahmen können dabei helfen, Kompetenzen zur Übernahme einer Brücken- und Lotsenfunktion im Sprachund Integrationsmittlungsprozess zu entwickeln und nachfolgend zu praktizieren. Dies impliziert abgesicherte Finanzierungsmöglichkeiten für die Hinzuziehung von Sprach- und Integrationsmittlerinnen in die Regelversorgung von Schwangeren und jungen Müttern und eine Implementierung in interprofessionelle Netzwerkstrukturen.
The Pathophysiology and Management of Diabetic Ketoacidosis in COVID-19 Patients: A Literature Review
Authors: Tilinca Mariana Cornelia , Gliga Maximilian Cosma , Varga Andreea 
Published: November 2021

Abstract
Diabetic individuals are considered a vulnerable population during the COVID-19 Pandemic, and several studies noted worse outcomes, including death, among those who get infected. Diabetic emergencies, such as ketoacidosis (DKA), are common and potentially life-threatening conditions in uncontrolled patients. While the pathophysiological background of the relationship between COVID-19 and DKA is not fully understood, early reports available so far indicate that patients with pre-existing diabetes who get infected with the SARS-CoV 2 virus are at higher risk of DKA. It was also suggested that DKA is a poor prognostic sign for infected patients, these being at higher risk of developing worse forms of COVID-19 disease and having high mortality. Therefore, healthcare personnel dealing with such patients face a considerable challenge, as the correct and safe emergency management of such cases is far from established. This article aimed to conduct a study that reviews the current published data available about patients with DKA and COVID-19.

Published: November 2021

Abstract

Introduction
The predictive potential of demographics, clinical characteristics, and inflammatory markers at admission to determine future intubation needs of hospitalised CoVID-19 patients is unknown. The study aimed to determine the predictive potential of elevated serum inflammatory markers in determining the need for intubation in CoVID-19 Patients.

Methods
In a retrospective cohort study of hospitalised SARS-CoV2 positive patients, single and multivariable regression analyses were used to determine covariate effects on intubation odds, and a minimax concave penalty regularised logistic regression was used to build a predictive model. A second prospective independent cohort tested the model.

Results
Systemic inflammatory markers obtained at admission were higher in patients that required subsequent intubation, and adjusted odds of intubation increased for every standard deviation above the mean for c-reactive protein (CRP) OR:2.8 (95% CI 1.8-4.5, p<0.001) and lactate dehydrogenase OR:2.1 (95% CI 1.33.3, p=0.002). A predictive model incorporating C-reactive protein, lactate dehydrogenase, and diabetes status at the time of admission predicted intubation status with an area under the curve (AUC) of 0.78 with corresponding sensitivity of 86%, specificity of 63%. This predictive model achieved an AUC of 0.83, 91% sensitivity, and 41% specificity on the validation cohort.

Conclusion
In patients hospitalised with CoVID-19, elevated serum inflammatory markers measured within the first twenty-four hours of admission are associated with an increased need for intubation. Additionally, a model of C-reactive protein, lactate dehydrogenase, and the presence of diabetes may play a predictive role in determining the future need for intubation.
A Case of Self-salvation in a Determined Chloroquine Suicide Attempt
Authors: Störmann Sylvère , Hoppe John , Steinert Daniela , Angstwurm Matthias W. 
Published: November 2021

Abstract
This report concerns a young man who attempted suicide by ingesting a cocktail with a lethal dose of chloroquine phosphate and large amounts of diazepam. On presentation, the patient was drowsy, unresponsive and in cardiogenic shock with severely impaired left ventricular function. Active charcoal and vasopressors were administered, and despite his intoxication with diazepam, a high-dose diazepam treatment was initiated in the hospital. It is concluded that diazepam in the cocktail played a vital role in the survival of this patient. With a rise in numbers, every emergency and intensive care physician should be familiar with chloroquine poisoning.
Pheochromocytoma, Fulminant Heart Failure, and a Phenylephrine Challenge. The Perioperative Management of Adrenalectomy in a Jehovah’s Witness Patient: A Case Report
Authors: Bachman Sarah A. , Peterson Ryan S. , Burrage Peter S. , Hickerson Leigh C 
Published: November 2021

Abstract
Perioperative management of pheochromocytoma in the setting of catecholamine-induced heart failure requires careful consideration of hemodynamic optimization and possible mechanical circulatory support. A Jehovah’s Witness patient with catecholamine-induced acutely decompensated heart failure required dependable afterload reduction for a cardio-protective strategy. This was emphasized due to the relative contraindication to perioperative anticoagulation required for mechanical circulatory support. A phenylephrine challenge clearly demonstrated adequate alpha blockade after only 24 hours of phenoxybenzamine treatment. This resulted in advancement of the surgery date. This case also highlights management of beta blockade, volume and salt loading, autologous blood transfusion, and profound post-operative vasoplegia in the setting of cardiogenic shock. Careful attention to hemodynamic optimization and cardio-protective strategies ultimately resulted in positive outcome for this challenging clinical scenario.
Methanol Poisoning Leading to Brain Death: A Case Report
Authors: Glowala Jakub , Richards Jeremy B. 
Published: November 2021

Abstract

Introduction
The COVID-19 pandemic has put increased stress on medical systems, infrastructure, and the public in expected and unexpected ways. This case report summarises an unexpected case of methanol poisoning from hand sanitiser ingestion due to changes in industry regulations, increased demand for cleaning products and severe psychosocial stressors brought on by the pandemic. Severe methanol toxicity results in profound metabolic disturbances, damage to the retina and optic nerves, and potentially death.

Case Presentation
The patient was a 26-year-old male with alcohol use disorder who presented with one day of nausea, vomiting, and abdominal pain after consuming hand sanitiser. Within a few hours, the patient had suffered multiple seizures, cardiac arrests and required admission to the ICU for emergent management of methanol poisoning. EEG and brain perfusion imaging were performed to confirm brain death, given concerns about the cranial nerve exam after methanol poisoning.

Conclusions
While rare, methanol toxicity remains a potentially fatal poisoning in the United States and worldwide. When healthcare and public resources are strained, healthcare professionals must consider particularly abnormal presentations. In patients suspected of brain death from methanol toxicity, cranial nerve examination may be unreliable. Therefore, additional testing is necessary to confirm brain death.
Water repellency decreases with increasing carbonate content and pH for different biocrust types on sand dunes
Authors: Drahorad Sylvie Laureen , Felde Vincent J. M. N. L. , Ellerbrock Ruth H. , Henss Anja 
Published: November 2021

Abstract
Biocrusts are biological communities that occupy the soil surface, accumulate organic matter and mineral particles and hence strongly affect the properties of the soils they cover. Moreover, by affecting water repellency, biocrusts may cause a preferential infiltration of rainwater, with a high impact on the formation of local water pathways, especially for sand dunes. The aim of this study is to shed light on the connections between water repellency and pH, carbonate and organic matter content in two dune ecosystems with different biocrust types. For this, we used contact angle measurements, gas volumetric carbonate determination and organic matter characterization via FT-IR and TOF-SIMS. In both ecosystems, moss-dominated biocrusts showed higher water repellency and higher amounts of organic matter compared to algal or cyanobacterial biocrusts. Surprisingly, the biocrusts of the two dune systems did not show differences in organic matter composition or organic coatings of the mineral grains. Biocrusts on the more acidic dunes showed a significantly higher level of water repellency as compared to higher carbonate containing dunes. We conclude that the driving factor for the increase in water repellency between cyanobacterial and moss-dominated biocrusts within one study site is the content of organic matter. However, when comparing the different study sites, we found that higher amounts of carbonate reduced biocrust water repellency.
Relation of influencing variables and weather conditions on rainfall partitioning by birch and pine trees
Authors: Zabret Katarina , Šraj Mojca 
Published: November 2021

Abstract
General weather conditions may have a strong influence on the individual elements of the hydrological cycle, an important part of which is rainfall interception. The influence of general weather conditions on this process was analysed, evaluating separately the influence of various variables on throughfall, stemflow, and rainfall interception for a wet (2014), a dry (2015), and an average (2016) year. The analysed data were measured for the case of birch and pine trees at a study site in the city of Ljubljana, Slovenia. The relationship between the components of rainfall partitioning and the influential variables for the selected years was estimated using two statistical models, namely boosted regression trees and random forest. The results of both implemented models complemented each other well, as both indicated the rainfall amount and the number of raindrops as the most influential variables. During the wet year 2014 rainfall duration seems to play an important role, correlating with the previously observed influence of the variables during the wetter leafless period. Similarly, during the dry year 2015, rainfall intensity had a significant influence on rainfall partitioning by the birch tree, again corresponding to the influences observed during the drier leafed period.
Effects of slow and fast pyrolysis biochar on N2O emissions and water availability of two soils with high water-filled pore space
Authors: Balashov Eugene , Buchkina Natalya , Šimanský Vladimir , Horák Ján 
Published: November 2021

Abstract
Biochars, depending on the types of feedstocks and technological conditions of pyrolysis, can vary significantly in their properties and, therefore, it is difficult to predict biochar-induced effects on nitrous oxide (N2O) emissions from various soils, their physical properties and water availability. The objectives of this study were (1) to quantify effects of slow pyrolysis biochar (BC) and fast pyrolysis biochar (PYRO) on physical and hydro-physical properties of sandy soil (Haplic Arenosol) and clayey loam soil (Gleyic Fluvisol), and (2) to assess corresponding N2O emissions from these two soils. The study included a 63-day long laboratory investigation. Two doses of BC or PYRO (15 t ha−1 and 30 t ha−1) were applied to the soils in combination or without nitrogen fertilizer (NH4NO3, 90 kg N ha−1). The obtained results have shown a significant decrease in the bulk density of sandy soil after it was amended with either rate of BC or PYRO. Water retention capacity of the soils in all the treatments with BC or PYRO increased considerably although no changes was found in the soil water-filled pore space (WFPS) which was higher than 60%. BC was increasing N2O emission rates from the sandy soil treated with N fertilizer, and reducing N2O emission rates from the clayey loam soil treated with N fertilizer. PYRO was more efficient and was reducing N2O emissions from both fertilized soils, but for the sandy soil the reduction was statistically significant only at higher dose (30 t ha−1) of the biochar.
Effect of mature spruce forest on canopy interception in subalpine conditions during three growing seasons

Published: November 2021

Abstract
The interception process in subalpine Norway spruce stands plays an important role in the distribution of throughfall. The natural mountain spruce forest where our measurements of throughfall and gross precipitation were carried out, is located on the tree line at an elevation of 1,420 m a.s.l. in the Western Tatra Mountains (Slovakia, Central Europe). This paper presents an evaluation of the interception process in a natural mature spruce stand during the growing season from May to October in 2018–2020. We also analyzed the daily precipitation events within each growing season and assigned to them individual synoptic types. The amount and distribution of precipitation during the growing season plays an important role in the precipitation-interception process, which confirming the evaluation of individual synoptic situations. During the monitored growing seasons, precipitation was normal (2018), sub-normal (2019) and above-normal (2020) in comparison with long-term precipitation (1988–2017). We recorded the highest precipitation in the normal and above-normal precipitation years during the north-eastern cyclonic synoptic situation (NEc). During these two periods, interception showed the lowest values in the dripping zone at the crown periphery, while in the precipitation sub-normal period (2019), the lowest interception was reached by the canopy gap. In the central crown zone near the stem, interception reached the highest value in each growing season. In the evaluated vegetation periods, interception reached values in the range of 19.6–24.1% of gross precipitation total in the canopy gap, 8.3–22.2% in the dripping zone at the crown periphery and 45.7–51.6% in the central crown zone near the stem. These regimes are expected to change in the Western Tatra Mts., as they have been affected by windstorms and insect outbreaks in recent decades. Under disturbance regimes, changes in interception as well as vegetation, at least for some period of time, are unavoidable.
Biocrust effects on soil infiltrability in the Mu Us Desert: Soil hydraulic properties analysis and modeling
Authors: Guan Hongjie , Liu Xinyu 
Published: November 2021

Abstract
The presence of biocrusts changes water infiltration in the Mu Us Desert. Knowledge of the hydraulic properties of biocrusts and parameterization of soil hydraulic properties are important to improve simulation of infiltration and soil water dynamics in vegetation-soil-water models. In this study, four treatments, including bare land with sporadic cyanobacterial biocrusts (BL), lichen-dominated biocrusts (LB), early-successional moss biocrusts (EMB), and late-successional moss biocrusts (LMB), were established to evaluate the effects of biocrust development on soil water infiltration in the Mu Us Desert, northwest of China. Moreover, a combined Wooding inverse approach was used for the estimation of soil hydraulic parameters. The results showed that infiltration rate followed the pattern BL > LB > EMB > LMB. Moreover, the LB, EMB, and LMB treatments had significantly lower infiltration rates than the BL treatment. The saturated soil moisture (θs
) and shape parameter (α
VG) for the EMB and LMB treatments were higher than that for the BL and LB treatments, although the difference among four treatments was insignificant. Water retention increased with biocrust development at high-pressure heads, whereas the opposite was observed at low-pressure heads. The development of biocrusts influences van Genuchten parameters, subsequently affects the water retention curve, and thereby alters available water in the biocrust layer. The findings regarding the parameterization of soil hydraulic properties have important implications for the simulation of eco-hydrological processes in dryland ecosystems.
