Published: March 2020

Background: China has experienced the largest migration during the past three decades. Compared with the permanent residents, migrants faced more obstacles in accessing essential health care services. This study aimed to explore the association between socioeconomic status and unmet inpatient service need among internal migrants in China. Methods: The data used in this study were from the 2014 nationally representative cross-sectional sample of internal migrants in China. All respondents were aged 15-59 years who had been living in local residence without the ‘Hukou’ for more than one month, and a total of 7592 migrants with inpatient service need were included in this analysis. Results: The migrants with unmet inpatient service need were 1667(21.96%). We found that internal migrants with higher socioeconomic defined by economic status(OR=1.74, 95 CI% 1.55-1.96) and educational attainment (OR=1.77, 95% CI 1.56-2.00) were more inclined to use inpatient services when needed, while the unemployed internal migrants (OR=0.36, 95% CI 0.32-0.41) were more likely to use inpatient service than the employed migrants. After adjustment for other demographic variables such as gender, age, marital status etc., these figures did not substantially change in model 2, the OR were 1.28(95% CI 1.12-1.46), 1.31(95% CI 1.13-1.52), and 0.59(95% CI 0.51-0.68), respectively. Conclusion: Internal migrants with higher socioeconomic defined by economic status and education attainment were more inclined to use inpatient services when needed, while the unemployed internal migrants were more likely to use inpatient service than the employed. This suggests that future policies should make the reimbursement more pro-poor among migrants and more effective policies targeting the migrants with low educational attainment and employed.
Evaluation of the four national lesbian, gay, bisexual, transgender, and queer (LGBTQ)-competent provider directories in the United States
Authors: Nowaskie Dustin Zachary
Published: March 2020

Background: Postponement and avoidance of healthcare by lesbian, gay, bisexual, transgender, and queer (LGBTQ) people can be attributed to various individual and systemic barriers. National directories of culturally-competent providers may serve as a bridge solution until LGBTQ health education becomes a requisite within standard medical education. This study seeks to evaluate these directories. Methods: In this qualitative study, characteristics such as populations served, number of providers, provider-specific feedback, and searchable criteria of the four national LGBTQ-competent provider directories in the United States, i.e., the Gay and Lesbian Medical Association (GLMA) Provider Directory, OutCare Health OutList, Referral Aggregator Database (RAD), and World Professional Association for Transgender Health (WPATH) Member Directory, were evaluated. Results: The GLMA Provider Directory and OutCare Health OutList both served the LGBTQ community while the RAD and WPATH Member Directory served the transgender community. The directories enumerated many providers: GLMA Provider Directory (n = 3961), OutCare Health OutList (n = 1900), RAD (n = 4051), and WPATH Member Directory (n = 1573). Only the OutCare Health OutList and RAD allowed provider-specific feedback. All directories provided nine fundamental searchable criteria (including provider name, location, specialty, population identity, service type, payment types, gender identity, and languages spoken) except the WPATH Member Directory which offered three criteria. Conclusion: The four national directories of LGBTQ-competent providers help address an essential need within the LGBTQ population by promoting equitable healthcare access. Provider-specific feedback and searchable criteria are important key characteristics to ensure cultural competency. By implementing these features, existing and future directories could better provide for the LGBTQ population.

Published: March 2020

Background: Serum Amyloid A (SAA) is an acute-phase reactant downstream of the pro-inflammatory cytokines released during virus infection. However, the role of this inflammatory marker in SARA-CoV-2 infection is yet to be elucidated. Here, we explored the potential use of SAA in serum as a biomarker for monitoring the clinical course of COVID-19 patients.Methods: The subjects included 95 COVID-19 patients discharged from the hospital with acute and / or convalescent phases data, among them 69 patients had paired data. Mann-Whitney U statistics and Wilcoxon signed-rank test were used to compare SAA level in the acute and convalescent phases. A subgroup of COVID-19 patients (n=9) participated in a follow-up examination with repeated blood collection reach five times during the hospitalization. The correlations of SAA levels with laboratory testing were then analyzed using the Spearman test.Results: The results of the data analysis show that the media SAA levels at acute phases were significantly higher (P < 0.05) compared to that at baseline. Furthermore, ascensional range of SAA were associated with the degree of COVID-19 severity. Media SAA levels at convalescent phases were significantly decreased (P < 0.05) compared to that at acute phases. The same phenomenon was seen in patients with and without comorbidities and with fever patients except without fever patients. Furthermore, The SAA concentration change in 9 COVID-19 patients of longitudinal follow-up along with the CT score and SARS-CoV-2 nucleic acid change. In the course of the disease, SAA changes were greater than CRP, lymphocytes, and neutrophils.Conclusions: The serum SAA levels were found to be significantly correlated with impending course of the COVID-19, and may serve as a useful biomarker to monitor the complicated clinical course of the disease.
Study on the Influence Coefficient of Residual Stress used to Estimate the Stress Life Curve of Gears
Authors: Wang Zhen , Chen Long , Liu Zhong-Ming , Cheng Jun-Wei
Published: March 2020

This study aims to estimate the gear S-N curve by the influence coefficient m of the residual stress at the root of the gear for providing theoretical basis and experimental support for the study of the bending fatigue performance of the gear. Based on the crack propagation theory and the linear damage accumulation theory, according to the Goodman relation, the residual stress is treated as the average stress. The spatial distribution of the residual stress is considered, and the residual stress is treated as a step function about depth, so the crack propagation process is divided into several stages. Through the fatigue test, the S-N curve of the gear is obtained. In order to avoid the influence of gear material and shape on the coefficient m, the S-N curve after heat treatment is used as the initial S-N curve, and the S-N curve after shot peening is used as the result curve. Through S-N curve, the influence coefficient m of tooth root residual stress is calculated, and the S-N curve of gears after shot peening is deduced by m value, which is compared with the S-N curve obtained by experiment. The influence coefficient m of residual stress calculated by S-N curve is 0.2132. The S-N curve of shot peening derived from m value is lnS=7.6963-0.0821lnN, which is consistent with the trend of S-N curve obtained by experiment, and the calculated data are more secure in the case of high cycle fatigue. The huge capital and labor cost of gear fatigue test can be saved by estimating gear S-N curve more accurately by m value. It provides a theoretical and experimental basis for the study of the influence coefficient of tooth root residual stress, and provides a solution for estimating the gear S-N curve.

Published: March 2020

Backgound: Glycated hemoglobin (HbA1c) is commonly used in the diagnosis and evaluation of glycemic control in diabetes, and may be influenced by several non-glycemic and glycemic factors, including albumin. This retrospective study investigated the influence of albumin on HbA1c and HbA1c-defined glycemic status. Methods: The demographic, hematological, and biochemical data were collected for 11,922 patients undergoing routine physical examination. Univariate and multivariate linear regression analyses, stratified analyses and interaction analyses, and multiple logistic regression were conducted to identify the association between albumin and HbA1c in people with different glycemic status. Results: HbA1c levels were inversely associated with serum albumin level ( P < 0.0001) in all participants. Risk factors leading to the association included age >45 years, high fasting plasma glucose (≥7.0 mmol/L), and anemia. The negative association between HbA1c and albumin was curved ( P < 0.0001) and had a threshold effect in the HbA1c-defined diabetic population; the association was significantly stronger when the albumin level fell below 41.4 g/L (β: –0.31, 95% CI: –0.45 to –0.17, P < 0.0001). A 2 g/L increase in albumin reduced the odds of HbA1c-defined dysglycemia, diabetes, and poor glycemia control by 12% to 36%, after adjustment for all possible confounders. Conclusions: HbA1c was inversely associated with albumin level in all participants, and the association was significantly stronger in people with diabetes (defined by HbA1c criteria). For diabetic patients with lower albumin level, there was an increased risk of an erroneous HbA1c-based identification and management of glycemic status.

Published: March 2020

Background: Investigate the association between AS and alopecia.Methods: Using over 1,000,000 patients’ data from Taiwan Longitudinal Health Insurance Database, we selected the sample with ICD code, diagnosing date, index date, and propensity score matching. We had 3,640 patients with AS and 14,560 non-AS controls. Cox proportional hazard model and Kaplan-Meier analysis were used to present the results.Results: The crude and adjusted hazard ratio of AS for developing alopecia showed no statistical significance in the Cox proportional hazard model [crude hazard ratio (HR) 1.16, 95% CI 0.67-1.99; adjusted HR 1.16, 95% CI 0.67-1.98]. Negative results were found as well in subgroup analysis (Age 20-40: HR 1.03, 95% CI 0.53-2.01; Age≧40: HR 1.49, 95% CI 0.58-3.80; Female: HR 1.17, 95% CI 0.43-3.17; Male: HR 1.15, 95% CI 0.61-2.19). A significant positive correlation was found between atopic dermatitis and alopecia (adjusted HR 8.05, 95% CI 1.11-58.14).Conclusions: No increased risk of alopecia was observed in AS patients
Assessing Ultra-Fine-Scale Factors to Improve Human West Nile Virus Disease Models in the Chicago Area
Authors: Uelmen Johnny , Irwin Patrick , Brown William , Karki Surendra , Ruiz Marilyn O'Hara , Li Bo , Smith Rebecca
Published: March 2020

Background: Since 1999, West Nile virus (WNV) has moved rapidly across the United States, resulting in tens of thousands of human cases. Both the number of human cases and the level of mosquito infection (MIR) vary across time and space and are related to numerous abiotic and biotic forces, ranging from differences in microclimates to socio-demographic factors. Because the interactions among these multiple factors affect the locally variable risk of WNV illness, it has been especially difficult to model human disease risk across varying spatial and temporal scales. Cook and DuPage Counties, comprising the city of Chicago and surrounding suburbs, are among the areas hardest hit by WNV in the United States. Despite active mosquito control efforts, there is consistent annual WNV presence, resulting in more than 285 confirmed WNV human cases and 20 deaths in the past 5 years in Cook County alone. Methods: A previous WNV model for the greater Chicago area identified the fifty-five most high and low risk study areas in the Northwest Mosquito Abatement District (NWMAD), an enclave ¼ the size of the previous study area. In these locations, human WNV risk was stratified by strength of predictive success, as indicated by differences in studentized residuals. Within these areas, an additional two-years of field collections and data processing was added to a 10-year WNV dataset and assessed by an ultra-fine-scale multivariate logistic regression model.Results: Multivariate statistical approaches revealed that this ultra-fine-scale model resulted in fewer explanatory variables while improving upon the fit of the existing model. Beyond mosquito infection rates and climatic factors, efforts to acquire additional covariates only slightly improve model predictive performance. Conclusions: These results suggest human WNV illness in the Chicago area may be associated with fewer, but increasingly critical, key variables at finer scales. Given limited resources, this study suggests a large variation in the significance to model performance, and provides guidance in covariate selection for optimal WNV human illness modeling.
COVID-19 outbreak in Italy: Experimental chest x-ray scoring system for quantifying and monitoring disease progression
Authors: Borghesi Andrea , Maroldi Roberto
Published: March 2020

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new virus recently isolated from humans. SARS-CoV-2 was discovered to be the pathogen responsible for a cluster of pneumonia associated with severe respiratory disease occurred in December 2019 in China. This novel pulmonary infection, formally called coronavirus disease 2019 (COVID-19), has spread rapidly in China and beyond. On 8 March 2020, the number of Italians with SARS-CoV-2 infection was 7375 with a 48% hospitalization rate. At present, chest computed tomography imaging is considered the most effective method for detection of lung abnormalities in early-stage disease and for quantitative assessment of severity and progression of COVID-19 infection. Although chest x-ray (CXR) is considered not sensitive for the detection of pulmonary involvement in the early stage of disease, we believe that, in the current emergency setting, CXR can be a useful diagnostic tool for monitoring the rapid progression of lung abnormalities in infected patients, particularly in intensive care units. In this article we present our experimental CXR scoring system that we are applying in hospitalized patients with COVID-19 pneumonia to quantify and monitor the severity and progression of this new infectious disease. We also present the results of our preliminary validation study on a sample of 100 hospitalized patients with SARS-CoV-2 infection for whom the final outcome (recovery or death) was available.

Published: March 2020

Background: Kanglaite injection (KLTi) has shown good clinical efficacy in the treatment of pancreatic ductal adenocarcinoma (PDAC). However, its molecular biological mechanisms are still unclear. This study used network pharmacology approach to investigate the molecular biological mechanisms of KLTi.Methods: Compounds in KLTi were screened using TCMSP and drug targets were obtained from the DRUGBANK. Next, the GEO database was searched for differentially expressed genes in cancerous tissues and healthy tissues of PDAC patients to identify targets. Subsequently, the protein-protein interaction data of KLTi and PDAC targets were constructed by BisoGenet. A visual analysis was done to extract KLTi candidate genes for PDAC. The candidate genes were enriched using GO and KEGG by Metascape, and the gene-pathway network was constructed to further screen the key genes.Results: A total of 10 active compounds and 36 drug targets were screened for KLTi, 919 differentially expressed genes associated with PDAC were identified from GEO, and 139 KLTi candidate genes against PDAC were excavated by BisoGenet. The gene-pathway network showed RELA, NFKB1, IKBKG, JUN, MAPK1, TP53, and AKT1 as the core genes, predicting that KLTi intervenes in PDAC by acting on these genes.Conclusions: Our study suggested that KLTi plays an anti-PDAC role by intervening in the cell cycle, inducing apoptosis, regulating protein binding, inhibiting nerve invasion, and down-regulating the NF-κB, MAPK, and PI3K-Akt signaling pathways. In addition, it might also directly participate in the pancreatic cancer pathway. These results provide new evidence and therapeutic direction for subsequent clinical applications and basic research on KLTi in PDAC.

Published: March 2020

To produce a firm and cohesive root plug to promote automated transplanting of nursery-grown seedlings, hydrolyzed soy protein-modified urea–formaldehyde (H-UF) resins were used to bind renewable substrate [mixture of coconut (Cocos nucifera) coir dust, coconut fiber, organic manure, perlite, vermiculite]. The resulting substrate block showed high density and nutrient concentrations in the peripheral portion and relatively low density and nutrient levels in the center. The porosity of the H-UF/substrate block was slightly lower than that of standard substrate. The electrical conductivity and pH were beneficial for germination and early seedling development. The modified resins in the substrate block existed in the form of spheres that adhered to each other and formed a porous structure from nano- to micrometer scale. In particular, the H-UF/substrate block increased the seedling height, stem diameter, root length, and leaf area of ‘Sujiao No. 5’ pepper (Capsicum annum) seedlings by 56.07%, 43.33%, 1.33%, and 89.63%, respectively, compared with those of seedlings grown in substrate without H-UF resin. The contents of nitrogen, phosphorus, and potassium in the shoot and root of pepper seedlings grown in H-UF/substrate blocks were enhanced by 39% to 69% compared with those of seedlings grown in standard substrate. The compressive strength of the H-UF/substrate block was 3.6-fold higher than that of substrate when 50% resin was added to the substrate. The results indicated that a combination of the substrate with the modified resin was suitable as a growth substrate for nursery production of pepper seedling plugs.

Despite the rapid growth rate, the scientific base and theoretical development of Internet marketing in Ukraine requires scientific justification and additional research. This paper highlights the problems associated with the unclear position among scientists and experts in defining the concept of “Internet marketing” because the concept is quite new and practically unexplored, consists of two words, each of which has its meaningful content.The paper aims, based on the analysis of conceptual theoretical approaches of scientists and marketers, to formulate the conceptual definition of “Internet marketing,” considering modern features of Internet marketing activity.The research considers the basic theoretical and practical definitions of “Internet marketing” in accordance with the conceptual and categorical approaches. According to the supporters of the descriptive approach, the definition of Internet marketing characterizes, as part of e-commerce, the set of Internet marketing tools, while ignoring the relationship with traditional marketing. Supporters of the conservative approach consider Internet marketing as an integral part of traditional marketing and do not pay due attention to the technical capabilities and limitations of the Internet.To form a comprehensive definition of Internet marketing, which would take into account all aspects of Internet marketing, this paper considers the Internet marketing features, according to the “6I” Internet marketing model of McDonald and Wilson, supplemented by characteristics of the modern conditions of the Ukrainian Internet market, like reactivity, dynamic pricing, innovation, complexity of implementation, and others.

This study aimed to investigate the presence of bovine herpesvirus 1 by molecular techniques in two cases of respiratory disease in beef cattle, reported from Amasya Province of Turkey in 2018. Nasal swab and lung tissue samples were taken. The presence of bovine herpesvirus-1 (BoHV-1) was confirmed by the PCR method using glycoprotein B (gB) gene-specific primers, and then the isolates were also subjected to partial sequencing. The results of the phylogenetic analysis revealed that the two new isolates in Turkey belonged to the same subclade as subtype 1.1 of BoHV-1, and both also had a 100% nucleotide (nt) homology with the Cooper reference strain of BoHV-1. These findings can enrich the gB sequence content data for BoHV-1 found in GenBank regarding Turkey.

The aim of the work was to present contemporary pet name trends, especially for cats and dogs. It also attempts to identify the origins of pet names. The research data consisted of the pet names of patients of a veterinary clinic in the years 2014-2018. The pet names of 36,487 dogs and 14,518 cats were analyzed statistically. The results obtained revealed relationships between the animal-human relationship, the species and sex of the animals. Among the most common dog names were diminutive male names (Max) and names borrowed from culture or mythology (Nero, Ares). The most universal name was Kuba, which occurred in both male and female dogs and cats. Among cats the most numerous were those called by diminutives of the word cat (Kicia) or by female names (Zuzia) and unnamed animals. Statistical analysis indicates a link between naming and the species: there were more nameless animals among cats than among dogs. A relationship between naming and the sex of dogs and cats was also noted: males were nameless more often than females.

Published: March 2020

The regional difference of complex Indian social structure and customs have a different impact on the nature of women’s work participation. The present study aims at unravelling the influence of social, cultural and economic forces in differentiating the level of women work participation in different eco-regions of West Bengal. The study is based purely on secondary sources and data have been collected from the Census of India. It is in the rural areas that the female work participation is directly linked to agriculture and allied activities and the study confines itself to an understanding of work participation of women only in the rural areas. The modern technological implication as a result of green revolution has a worse impact on women work participation particularly in the South Bengal plain and some parts of East Rarh Plain region. The high gender gap is noticed in Nadia district located in the middle part of South Bengal Plain causes very high withdrawn of female from there. Effect of socioeconomic variables, work participation of Scheduled component in main economic activity is also varied from the non-scheduled component. Non-scheduled worker participated more in non-agricultural sector rather than the scheduled counter parts. Subsequently, the low growth rate of female work participation represents a distress picture in work force structure which is a cause of worried also.

Published: March 2020

OBJECTIVE: This study investigated the cases in which the fetal ascending aorta is larger than the main pulmonary artery on the three-vessel view and aimed to determine the relationship between the larger ascending aorta and major cardiac anomalies.STUDY DESIGN: Pregnancies between 18-24 gestational weeks who underwent detailed second-trimester screening during 2015-2019 were evaluated. Cases whose fetal ascending aorta diameter was larger than fetal main pulmonary artery diameter on the three-vessel view despite normal four-chamber view were analyzed. Prenatal and postnatal echocardiography studies were performed for each case.RESULTS: Fetal ascending aorta diameter larger than fetal main pulmonary artery diameter on the three-vessel view despite normal four-chamber view was detected in 21 fetuses in a total of 3810 pregnancies (0.55%), and 10 (47.6%) of them had major congenital heart disease. The diagnosis of Tetralogy of Fallot, double outlet right ventricle, ventricular septal defect, pulmonary valve stenosis, and moderate to severe tricuspid regurgitation were confirmed with prenatal/postnatal echocardiography studies. The highest ratio of ascending aorta/main pulmonary artery was 1.4 in a fetus with a double outlet right ventricle and pulmonary valve stenosis.CONCLUSION: The fetal ratio of ascending aorta/main pulmonary artery larger than 1 on the three-vessel view may be a sign of certain cardiac anomalies. Nevertheless, this rate is not an indicator of a serious cardiac defect in all cases. Fetal advanced echocardiography and early postnatal cardiac evaluation should be done to confirm the diagnosis.

A través de algunas técnicas de análisis multivariante, particularmente los análisis de conglomerados y discriminante, se estudian 174 microempresas marginadas en el giro de alimentos y bebidas en la zona fronteriza de Baja California, a fin de determinar las características que rigen las decisiones propias de su funcionamiento. Los resultados muestran comportamientos diferenciados de los microempresarios de acuerdo con su edad, condición familiar, educación y zona geográficas de procedencia. Sin embargo, sobresale la relevancia de la educación como determinante de la calidad de la gestión de la empresa y a su vez como una señal en el entorno que atrae la confianza tanto de los proveedores como clientes. Por otro lado se hace patente que el financiamiento, bajo ciertas circunstancias, podría ayudar a mejorar la eficiencia de muchas de estas microempresas.

The composition of the gums confers some physical characteristics that make it resistant to mechanical stimulation.  The objective of the study was to compare the difference of the utilized forces when performing cuts in the anterior and posterior sections of porcine gingival tissue, measuring the depth of the tissue. A comparative descriptive study was performed with a non-probability convenience sampling, sectioned pig mandibles were used. The experimental trials were performed with an EZ-S SHIMADZU texture analyzer. All of the samples were submitted to a vertical shear force, thus identified the force level used to perform the incision and its depth. the necessary force to perform a cut in porcine gingival tissue was evaluated, comparing the posterior section (39.3571 Newton and 2.160 mm)  and  with the anterior ( 37.8424 newton and 1.747 mm), just as the depth of said cut, showing a statistical difference on the depth, (p=0.022 p< 0.59); regarding the force, no statistically significant difference was found. In the analyzed samples where the shear force in the posterior and anterior section were compared, no difference was found in both groups; as for the cut depth, this was greater in the posterior section than in the anterior.

Existe evidencia sobre los factores de riesgos asociados a la infección de la herida quirúrgica (IHQ), pero se desconocen estudios que hayan evaluado los factores asociados a la letalidad por la IHQ. Se propone un estudio para determinar los factores asociados a la letalidad en pacientes que desarrollaron una IHQ. Se realizó un estudio de casos y controles anidado a una cohorte de pacientes adultos diagnosticados con IHQ durante el periodo 2015 – 2016, en un hospital universitario de la región sur de Colombia. Los casos fueron pacientes con IHQ que presentaron letalidad dentro de los 30 días posteriores al inicio de la infección y los controles aquellos con IHQ que no fallecieron durante los 30 días. 150 pacientes cumplieron los criterios de selección. Los casos (fallecidos) correspondieron al 19,3%, quedando el grupo de los controles (vivos) con un 80,7%. Se encontró que controlando la edad y los días de hospitalización previos al procedimiento quirúrgico, la IHQ tipo órgano espacio es un factor asociado con letalidad en pacientes infectados (OR=2,5 IC95% 1,1 – 6,1). La letalidad en pacientes con IHQ fue elevada y representa un problema de salud pública por las consecuencias que ocasiona al paciente.

Se realizó una revisión sistemática para identificar microorganismos reportados como agentes contaminantes en teléfonos celulares de trabajadores de la salud, que realizan actividades en ambientes clínicos. Se incluyeron publicaciones entre 2008 y 2018, mediante búsqueda en seis bases de datos usando palabras clave como “nosocomial pathogen” "healthcare workers" y "cell phone", entre otros. Dos investigadores de forma independiente realizaron la búsqueda y revisión de artículos. La calidad de los mismos se evaluó mediante lista de chequeo STROBE. Veintiún artículos fueron analizados. En todos los estudios se identificó presencia de contaminación en los celulares de los trabajadores de la salud, con una mediana de 84,3%, resaltando la presencia de Staphylococcus aureus (85,7%) y Escherichia coli (61,9%). Se concluye que el uso de los teléfonos celulares en ambiente hospitalario por parte de los trabajadores de la salud se constituye en una fuente potencial de trasmisión de microorganismos de interés clínico.

Wpływ homoseksualizmu na niezdolność do zawarcia małżeństwa w wyroku Roty Rzymskiej c. Arokiaraj z 6 lipca 2011 roku
Authors: Dzierżon Ginter
Published: March 2020

W zaprezentowanym opracowaniu dokonano szczegółowej analizy wyroku Roty Rzymskiej c. Arokiaraj z 6 lipca 2011 roku wydanego w sprawie Senogallien. z tytułu niezdolności do podjęcia istotnych obowiązków małżeńskich wynikających z homoseksualizmu powoda.

Według Autora, na pozytywne rozstrzygnięcie turnusu rotalnego wprawdzie zasadniczo wpłynęły zgodne opinie biegłych. Diagnozy sporządzone przez ekspertów były koherentne wizerunkiem osoby były koherentne wizerunkiem osoby nakreślonym w oświadczeniach stron oraz zeznaniach świadków z którymi powód obcował. W ocenie stanu faktycznego turnus rotalny pod przewodnictwem Ksawiera Leona Arokiaraja wziął pod uwagę wszystkie środki dowodowe.

Na podstawie analizy treści wyroku jego redaktor wykazał, iż powołani w Rocie Rzymskiej biegli rozpoznali u powoda nie tylko homoseksualizm pierwotny, ale również osobowość zależną, której źródeł upatrywali w toksycznych uwarunkowaniach rodzinnych. Na orzeczoną zatem niezdolność do zawarcia małżeństwa wpłynął nie tylko homoseksualizm pierwotny jako jednostka autonomiczna, ale połączenie wskazanych zaburzeń.

Mając na uwadze te fakty Autor opracowania wysunął następujące zalecenie dla sądownictwa niższych stopni jurysdykcyjnych: biegli biorący udział w procesach, o ile to możliwe, na występujące zaburzenia osobowości powinni spojrzeć nie tylko jednoaspektowo, ale wieloaspektowo. Taki punkt widzenia bowiem umożliwi im nakreślenie integralnego wizerunku osoby.

The Impact of Various Blood Pressure Measurements on Cardiovascular Outcomes
Authors: Bakogiannis Constantinos , Stavropoulos Konstantinos , Papadopoulos Christodoulos , Papademetriou Vasilios
Published: March 2020

Hypertension is a potent risk factor for cardiovascular morbidity and mortality. High blood pressure (BP) correlates closely with all-cause and cardiovascular mortality. Although the gold standard remains office BP (auscultatory or automated), other methods (central or out-of-office) are gaining popularity as better predictors of CV events. In this review, we investigated the prognostic value of each method of BP measurement and explored their advantages and pitfalls. Unattended automated office BP is a novel technique of BP measurement with promising data. Ambulatory BP monitoring, and to a lesser extent, home BP measurements, seem to predict cardiovascular events and mortality outcomes better, while at the same time, they can help distinguish hypertensive phenotypes. Data on the association of central BP levels with cardiovascular and mortality outcomes, are conflicting. Future extensive cross-sectional and longitudinal studies are needed to evaluate head-to-head the corresponding levels and results of each method of BP measurement, as well as to highlight disparities in their prognostic utility.

Background:

Ofe-Owerri is an expensive traditional soup in Nigeria, prepared using Oha
(Pterocarpus soyauxi), Ukazi (Gnetum africanum), Uziza (Piper guineense) and cocoyam (Colocasia
esculanta) as the major vegetables. The soup is highly celebrated for its traditional therapeutic and
nutritional potentials.

Objective:

In this study, we assessed the proximate and mineral components, sensory and microbial
qualities of the Ofe-Owerri soup in a cooked and packaged form. Antioxidant status and phytoconstituents
of the major vegetables of the soup were also determined.

Methods:

Established methods were used as previously reported in the literature.

Results:

Calcium was the most concentrated mineral, whereas lead was absent. High moisture
(63.45%), crude protein (14.60%) and fat (13.27%) were found in the soup. The major ingredients
(vegetables) used to prepare Ofe-Owerri contain phytochemicals such as phenolic compounds and
saponins, and showed potent antioxidant activity in various in vitro models, with uziza displaying the
highest scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The vegetables
exhibit reductive capacity against oxidants, and chelation of metallic free radicals. There was no significant
difference (p≤0.05) in the sensory parameters of Ofe-Owerri soup kept frozen in foil and
plastic containers, respectively, for 21 days.

Conclusion:

This study showed that Ofe-Owerri is a good dietary source of nutrients and possesses
phytoconstituents with potential beneficial health effects. When properly packaged, the soup can be
stored safely for up to three weeks.
The Development of Stem Cell-Based Treatment for Acute Ischemic Cerebral Injury
Authors: Bai Xiaojie , Xu Jun , Zhu Tiantian , He Yuanyuan , Zhang Hong
Published: March 2020

Acute ischemic brain injury is a serious disease that severely endangers the life safety of patients. Such disease is hard to predict and highly lethal with very limited effective treatments currently. Although currently, there exist treatments like drug therapy, hyperbaric oxygen therapy, rehabilitation therapy and other treatments in clinical practice, these are not significantly effective for patients when the situation is severe. Thus scientists must explore more effective treatments. Stem cells are undifferentiated cells with a strong potential of self-renewal and differentiate into various types of tissues and organs. Their emergence has brought new hopes for overcoming difficult diseases, further improving medical technology and promoting the development of modern medicine. Some combining therapies and genetically modified stem cell therapy have also been proven to produce obvious neuroprotective function for acute ischemic brain injury. This review is an introduction to the current research findings and discusses the definition, origin and classification of stem cells, as well as the future prospects of the stem cell-based treatment for acute ischemic cerebral injury.
