ResumenMuchos animales se encuentran entretejidos en las visiones cósmicas de diferentes culturas del mundo. En este contexto varias especies han sido idealizadas como referentes que sintetizan atributos apreciados por el hombre como poder, valor, nobleza, así como fuerzas de la naturaleza o de lo desconocido. Con frecuencia son animales grandes los que han capturado la atención humana desde sus orígenes, como lo refleja el arte parietal antiguo. Probablemente esto obedece a que se les consideró importantes para la vida cotidiana y también a su supuesta influencia en mitos de mundos paralelos.En varias culturas alrededor del mundo se ha asignado a los osos un sitio prominente. Se conocen rituales y cultos relacionados con la presencia del oso en distintos grupos humanos en Asia, en pueblos originarios de Norteamérica y culturas de los Andes. Estas manifestaciones ocurren, por lo general, en sociedades que se encuentran asentadas en territorios dentro las principales áreas de distintas especies de osos. Sin embargo, en partes marginales de territorios ocupados por osos, las referencias culturales a ellos son escasas. Por ejemplo, no se había reportado la representación de estos mamíferos en las culturas que se desarrollaron en Mesoamérica.Trabajos arqueológicos recientes en el sitio de Tancama (Querétaro, México), ocupado por un grupo de afinidad Huasteca cuya mayor actividad se dio en el período clásico (entre 500 y 700 d.C.; fechas de C14), han revelado una escultura de barro asociada con restos de uno de los edificios principales, que representa un oso de cuerpo entero (se determinó como un oso negro,Ursus americanus, dado que es la única especie presente en el área). Además de la escultura, se encontraron vasijas y fragmentos cerámicos, excavados en otros edificios, que muestran rasgos diagnósticos de la cabeza de un oso.El presente estudio analiza este primer y singular hallazgo para Mesoamérica, enfatizando su relevancia para la región. Se analizan las relaciones entre la efigie principal de oso como parte de un edificio y las numerosas vasijas con representaciones ursiformes, para explorar el posible significado cultural local de esta especie animal.
Occlusion of left main coronary artery presenting with ventricular fibrillation in teenagers: an unrecognised cause of sudden death?
Authors: Marshall Mayme , Balaji Seshadri 
Published: July 2020

AbstractIn young patients with unexplained ventricular fibrillation, coronary occlusion may be missed by echocardiogram and misinterpreted by CT. We report two patients presenting with ventricular fibrillation and initially negative workup, later identified to have occlusion of left main coronary artery. We demonstrate the importance of angiography to rule out coronary occlusion in patients with unexplained ventricular fibrillation.

AbstractTechniques for performing the Fontan completion procedure after Kawashima procedure have developed in recent years. This paper presents a case in which we performed an off-pump hepatic-to-azygos connection by autologous pericardial roll via thoracotomy as a modified Fontan completion. The operation wound was limited, and the short-term follow-up was satisfactory. Notably, it was found that the autologous pericardium might require a shorter period of anticoagulation treatment than what is needed for artificial prosthetic materials.

AbstractObjectiveWork-related stress presents a significant impact on work performance and physical health. It has been associated with the onset of a multitude of symptoms. The main aim of this investigation is to better understand the impact of post-traumatic stress symptomatology, using a specific self-assessment questionnaire, in subjects experiencing occupational stress with the rationale to address the variegated symptoms expressed by this particular population in a post-traumatic dimensional perspective.MethodsAuthors collected socio-demographic, occupational, and clinical data. They utilized Trauma and Loss Spectrum Self Report (TALS-SR), a questionnaire investigating post-traumatic stress symptoms. The population size was 345 subjects who presented at the Occupational Health Department of a university hospital over a 3 years period (2016–2018).ResultsData analysis revealed 33.9% of subjects who met post-traumatic stress disorder (PTSD) criteria. Gender distribution of this set was (36.4% female, 31% male). A family history or personal history of mental disorders were related to higher scores in almost all TALS-SR domains and were related, respectively, to higher scores of criterion B “intrusion symptoms” (P = .014), criterion D “negative alterations in cognitions and mood” (P = .023), and criterion E “arousal” (P = .033) of PTSD. Differences in TALS-SR scores also emerged based on age and gender.ConclusionsPTSD symptoms manifest at a significant level in those who experience work-related stress. Personal background of individuals, both in terms of family and personal history for mental disorders, seems to increase their vulnerability to develop post-traumatic stress symptoms. This study suggests the importance of evaluating occupational stress from a post-traumatic stress perspective also at an early stage.

AbstractObjective:The aim of this study was an assessment of the effects of urbanisation level, family size and parental education on body mass index (BMI) and mid-upper arm circumference (MUAC) among Polish schoolchildren in cross-sectional surveys conducted between 1966 and 2012.Design:The analysis involved schoolchildren measured in four Polish Anthropological Surveys (1966, 1978, 1988 and 2012). Socio-economic factors involved: urbanisation level (city, town and village), family size (one child, two children, three children, four or more children), and father’s and mother’s education (lower and higher education).Setting:Regions in Poland – cities: Warsaw, Lodz and Wroclaw; towns: Bystrzyca Klodzka, Pinczow, Siemiatycze, Wolsztyn and their rural surroundings.Participants:A total sample consisted of 63 757 children (31 774 boys and 31 983 girls) aged 7–18 years.Results:Between 1966 and 1988, both BMI and MUAC had significantly higher values in children from cities, in families with one child and with higher parental education (P < 0·05). However, MUAC revealed significant differences between particular socio-economic groups more frequently than BMI. In 2012, urbanisation level and parental education ceased to show a differentiating effect on both indicators, while family size remained a significant social factor for both measures (BMI: P < 0·05; MUAC: P < 0·01).Conclusions:Since MUAC reflected socio-economic differences more frequently than BMI, it could be a more sensitive and reliable anthropometric measure revealing the effects of socio-economic factors on children’s nutritional status.
Social work in hospice and palliative care in Europe: Findings from an EAPC survey

Published: July 2020

AbstractObjectivesSocial work is considered to be a key player in Hospice and Palliative Care. To prove this claim, the Social Worker Task Force within the European Association for Palliative Care (EAPC) decided to carry out a survey. The aim of this survey was to generate basic data and thus to create a basis for further development of Palliative Care Social Work (PCSW) in Europe.MethodThe online survey consisted of two parts: in Part 1, the 57 collective members of the EAPC were asked to fill in an online questionnaire containing questions about basic data. In Part 2, individual Palliative Care Social Workers (SWs) from all over Europe were asked to fill in another questionnaire with a focus on the basic conditions concerning their jobs as well, as on their tasks and roles.ResultsThirty-two collective members of the EAPC completed the online questionnaire. SWs can be found in all of the Palliative Care settings, but there are considerable differences between the countries concerning the prevalence of SWs. Only five countries (20%) reported specialized qualification training in PCSW and just around half of the responding SWs had such a specialized training. The responding SWs (n = 360) were quite content with their working conditions. Tasks concerning patient and family and tasks concerning the interprofessional team were most prominent. There is a significant role overlap with other professions.Significance of resultsThe study reveals a very mixed picture of PCSW in Europe. This could be due to the high adaptability of social work, which is to be as flexible as possible to the needs of its clients. However, significant patterns, similarities, and differences emerge. The present study may, therefore, serve as a basis for further in-depth studies.
Do Hispanics prefer to be full code at the end of life? The impact of palliative care consults on clarifying code status preferences and hospice referrals in Spanish-speaking patients

AbstractBackgroundHispanics often have disparities at the end of life. They are more likely to die full code and less likely to have discussions regarding prognosis and do not resuscitate (DNR)/do not intubate (DNI), despite studies showing Hispanic values comfort over the extension of life. Barriers to patient-centered care include language,socioeconomic status and health literacy.ContextWe evaluated the impact of palliative care (PC) consults on the change of code status and hospice referrals, comparing seriously ill Hispanic and non-Hispanic white patients.MethodA retrospective cohort study of all white and Hispanic patients referred to the PC service of a county hospital from 2006 to 2012. We evaluated ethnicity, language, code status at admission and after PC consult, and hospice discharge. Chi-squared tests were used to analyze characteristics among three groups: non-Hispanic white, English-speaking Hispanic, and Spanish-speaking Hispanic patients.ResultsOf 925 patients, 511 (55%) were non-Hispanic white, 208 (23%) were English-speaking Hispanic, and 206 (22%) were Spanish-speaking Hispanic patients. On admission, there was no statistically significant difference in code status among the three groups (57%, 64%, and 59% were full code, respectively, p = 0.5). After PC consults, Spanish-speaking Hispanic patients were more likely to change their code status to DNR/DNI when compared with non-Hispanic white and English-speaking Hispanic patients (44% vs. 32% vs. 28%, p = 0.05). Spanish-speaking Hispanic patients were more likely to be discharged to hospice when compared with English-speaking Hispanics and non-Hispanic whites (33%, 29%, and 23%, respectively, p = 0.04).Significance of resultsSpanish-speaking Hispanic patients were more likely to change from full code to DNR/DNI compared with non-Hispanic white and English-speaking Hispanic patients, despite similar code status preferences on admission. They were also more likely to be discharged to hospice. PC consults may play an important role in helping patients to align their care with their values and may prevent unwanted aggressive interventions at the end of life.
Local Responses to a Global Pandemic: Women Mayors Lead the Way
Authors: Funk Kendall D. 
Published: July 2020

AbstractEven before the novel coronavirus, COVID-19, was declared a pandemic, prominent women mayors in the United States enacted proactive and innovative policies to prevent local outbreaks and soften the social and economic repercussions. Several Black women mayors, in particular, have led the way in local pandemic response efforts. This article identifies four major features of these and other women mayors’ early responses. First, women mayors demonstrated proactive leadership even when faced with pushback. Second, these mayors advocated for transparent and evidence-based decision-making at all levels of government. Third, they enacted measures to protect vulnerable communities and reduce disparities. Fourth, they actively shared advice on best practices and lessons learned, and provided examples for other local leaders to follow. The article concludes by situating these responses in the larger research on gender and leadership and asks whether these women's actions are unique or part of a systematic trend of gendered responses to the pandemic.

AbstractThe development of the fetal movement acceleration measurement (FMAM) recorder has enabled the accurate counting of gross fetal movements. The aim of the study was to investigate whether gross fetal movement is related to a newborn’s size. A total of 90 pregnant women who delivered singleton infant at term were recruited. Gross fetal movements were counted using an FMAM recorder during maternal sleep. The ratio of movement positive 10-s epochs to all epochs during one night was calculated as an index of fetal movement. Independent explanatory variables for the fetal movement index were selected from eight possibilities, that is, maternal age, gestational week, and the six physical measures of the newborn (height, weight, head circumference, chest circumference, Kaup index, and the ratio of head to chest circumference) with the stepwise regression procedure. The selected physical variables and the fetal movement index were analyzed using multiple regression analysis. A total of 2812.95 h from 423 night records were available. Gestational weeks and weight of the newborn were selected as the significant independent variables. Multiple regression analysis revealed that newborn weight had a positive correlation with the fetal movement index (p < 0.0001). The multiple regression equation was “The fetal movement index (%) = 34.9989−0.9088 × gestational weeks + 0.0033 × newborn weight (g).” A person’s physical ability and lifetime activity level may originate from fetal health. This study may provide a new way of looking at the Developmental Origins of Health and Disease theory.

Abstract
Gestational stress is associated with many maternal and child complications, however, this association must be taken with care, since there are studies that find inconsistent results between stress measures and maternal complications. It is believed that the lack of convergence is due to the way in which gestational stress is evaluated.
The aim of the present study was to design and validate an instrument based on a bio-psycho-social model of gestational stress. The design and validation process of the inventory was divided into four phases: (a) Construction of the items bank and content validity, (b) construct validity, (c) inventory reliability and (d) convergent and discriminant validity with psychometric instruments that have been used in other investigations to evaluate gestational stress.
A valid and reliable Stressors and Modulators of Gestational Stress Inventory (SMGSI) conformed by two scales was developed: (a) Gestational stressors, which is formed by two factors, the psychological stressors and social stressors with a variance of 48.5% and 51.8% and a reliability of .79 and .67, respectively; and (b) gestational stress modulators integrated by 8 items that explain 55.2% of the variance and with a reliability of .92. In conclusion, a valid and reliable tool was obtained that measures gestational stress from a bio-psycho-social perspective. This inventory allows for the identification of allostatic and pantostatic stress, making it useful as a diagnostic tool to prevent maternal and childhood complications that are associated with chronic gestational stress.

AbstractGiant chickweed [Myosoton aquaticum (L.) Moench], a troublesome broadleaf weed species, is widespread in winter wheat (Triticum aestivum L.) fields in China. However, limited information is available on its germination and seedling emergence ecology. Thus, three M. aquaticum populations (JS, HN, and AH) from different geographic regions were studied under laboratory conditions to determine the effects of different environmental factors on germination or seedling emergence. The seeds germinated at a relatively wide constant temperature range of 5 to 25 C; however, the optimal temperature for germination varied among the populations. Compared with constant temperatures, fluctuating temperatures with the same mean significantly improved the final germination of all populations. Light was not required for germination. The seeds germinated under a wide pH range of 3 to 10, and the optimum pH was 6 to 7, with a final germination percentage of 81% to 95%. The seeds of all populations showed similar sensitivities to osmotic potential and similar high tolerances of saline conditions. The seedling emergence of all populations decreased with increasing burial depth, and no emergence was observed when the seeds were buried more than 3 cm, but the AH population showed higher sensitivity to burial depth than the others. The results generated from this study will contribute to the development of integrated M. aquaticum management strategies for winter wheat fields in China, and deep plowing and late sowing of autumn-sown wheat are suggested for managing M. aquaticum, as it showed lower germination at a low temperature and under relatively deep burial.

AbstractThe origin and reactivity of dissolved organic matter (DOM) have received attention for decades due to the key role DOM plays in global carbon cycling and the ecology of aquatic systems. However, DOM dynamics in river networks remain unresolved, hampered by the lack of data integrating the spatial and temporal dimensions inherent to riverine ecosystems. Here we examine the longitudinal patterns of dissolved organic carbon (DOC) concentration and DOM chemical diversity along a temperate river network under different hydrological conditions, encompassing small headwater streams to the river mouth and base flow to storm events. We show that, during nonstorm conditions, the concentration of DOC and the chemical diversity of DOM exhibit their maxima in the middle section of the network, depicting a bell‐shaped pattern along the river continuum. In contrast, DOM shows a homogeneous longitudinal pattern during storm events, with highly concentrated and diverse DOM along the river network. We posit that these emerging patterns result from changes in the relative influence of catchment versus in‐stream biogeochemical processes along the river continuum and that the degree of influence is modulated by river network hydrology. Based on these findings we put forward the “Bending DOM Concept,” a new conceptual framework around which testable hypotheses on the spatiotemporal dynamics of DOM and the functioning of temperate river networks may be formulated.

AbstractThe ability of membrane technologies to dynamically tune the transport behavior for gases and liquids is critical for their applications. Although various methods have been developed to improve membrane success, tradeoffs still exist among their properties, such as permeability, selectivity, fouling resistance, and stability, which can greatly affect the performance of membranes. Existing elastomeric membrane designs can provide antifracture properties and flexibility; however, these designs still face certain challenges, such as low tensile strength and reliability. Additionally, researchers have not yet thoroughly developed membranes that can avoid fouling issues while realizing precise dynamic control over the transport substances. In this study, we show a versatile strategy for preparing graphene oxide-reinforced elastomeric liquid gating membranes that can finely modulate and dynamically tune the sorting of a wide range of gases and liquids under constant applied pressures. Moreover, the produced membranes exhibit antifouling properties and are adaptable to different length scales, pressures, and environments. The filling of graphene oxide in the thermoplastic polyurethane matrix enhances the composites through hydrogen bonds. Experiments and theoretical calculations are carried out to demonstrate the stability of our system. Our membrane exhibits good stretchability, recovery, and durability due to the elastic nature of the solid matrix and dynamic nature of the gating liquid. Dynamic control over the transport of gases and liquids is achieved through our optimized interfacial design and controllable pore deformation, which is induced by mechanical stimuli. Our strategy will create new opportunities for many applications, such as gas-involved chemical reactions, multiphase separation, microfluidics, multiphase microreactors, and particulate material synthesis.
