Maternal gestational diabetes mellitus associates with altered gut microbiome composition and head circumference abnormalities in male offspring.

The impact of gestational diabetes mellitus (GDM) on maternal or infant microbiome trajectory remains poorly understood. Utilizing large-scale longitudinal fecal samples from 264 mother-baby dyads, we present the gut microbiome trajectory of the mothers throughout pregnancy and infants during the first year of life. GDM mothers had a distinct microbiome diversity and composition during the gestation period. GDM leaves fingerprints on the infant's gut microbiome, which are confounded by delivery mode. Further, Clostridium species positively correlate with a larger head circumference at month 12 in male offspring but not females. The gut microbiome of GDM mothers with male fetuses displays depleted gut-brain modules, including acetate synthesis I and degradation and glutamate synthesis II. The gut microbiome of female infants of GDM mothers has higher histamine degradation and dopamine degradation. Together, our integrative analysis indicates that GDM affects maternal and infant gut composition, which is associated with sexually dimorphic infant head growth.

Relationality: The Role of Connectedness in the Social Ecology of Resilience.

Previous work has focused on the role of social capital on resilience. However, this research tends to search for civic and other organizations, often formal institutionalized groups which, when they are not found, leads to questions about how social networks are possibly governed. Without formal organizational structures to govern these networks, how is pro-environmental/pro-social behavior sustained. In this article, we focus on a diffused mechanism for collective action, which is referred to as relationality. Relationality is a theory that underscores how social connectedness, through mechanisms of empathy, foster collective action in noncentralized modes of network governance. The concept of relationality addresses important issues not considered by the literature on social capital --so being, we will refer to relational elements as relational capital. Relational capital constitutes a type of asset that communities can activate vis-a-vis environmental and other perturbation. As we describe, the evidence for relationality as an important mechanism for sustainability and resilience is accumulating.

Selective plasticity of callosal neurons in the adult contralesional cortex following murine traumatic brain injury.

Traumatic brain injury (TBI) results in deficits that are often followed by recovery. The contralesional cortex can contribute to this process but how distinct contralesional neurons and circuits respond to injury remains to be determined. To unravel adaptations in the contralesional cortex, we used chronic in vivo two-photon imaging. We observed a general decrease in spine density with concomitant changes in spine dynamics over time. With retrograde co-labeling techniques, we showed that callosal neurons are uniquely affected by and responsive to TBI. To elucidate circuit connectivity, we used monosynaptic rabies tracing, clearing techniques and histology. We demonstrate that contralesional callosal neurons adapt their input circuitry by strengthening ipsilateral connections from pre-connected areas. Finally, functional in vivo two-photon imaging demonstrates that the restoration of pre-synaptic circuitry parallels the restoration of callosal activity patterns. Taken together our study thus delineates how callosal neurons structurally and functionally adapt following a contralateral murine TBI.

Dignified Palliative Long-Term Care: An Interpretive Systemic Framework of End-of-Life Integrated Care Pathway for Terminally Ill Chinese Older Adults.

PURPOSE: To critically examine the system dynamics necessary for successfully implementing a novel end-of-life integrated care pathway (EoL-ICP) program in promoting dignity and quality of life among terminally-ill Chinese nursing home residents. METHODS: Thirty stakeholders were recruited to participate in 4 interpretive-systemic focus groups. RESULTS: Framework analysis revealed 10 themes, organized into 3 categories, namely, (1) Regulatory Empowerment (interdisciplinary teamwork, resource allocation, culture building, collaborative policy making), (2) Family-Centered Care (continuity of care, family care conference, partnership in care), and (3) Collective Compassion (devotion in care, empathic understanding, compassionate actions). CONCLUSIONS: These findings highlight the importance of organizational structure, social discourse, and shared meaning in the provision of EoL-ICP in Chinese societies, underscoring the significant triangulation between political, cultural, and spiritual contexts embodied in the experience of dignity.

A comparative study on resilience level between WHO health promoting schools and other schools among a Chinese population.

The WHO health promoting school (HPS) approach covers key areas including school-based programmes improving students' psychological health, but there have been few studies evaluating the resilience performance of these schools. This study compared the resilience scores between schools within the healthy school award (HSA) scheme (HPS group) and those not (non-HPS group). We conducted a cross-sectional survey of grade-one students (aged 12), all teachers and parents of mainstream secondary schools recruited by stratified random sampling in one large Territory of Hong Kong using validated resilience questionnaires during November-December 2005. Four non-HPS and four HPS secondary schools were recruited, respectively, involving 1408 students, 891 parents and 91 teachers, with similar baseline characteristics. The HPS students were found to have better scores than non-HPS students (average age 12.4 year-old in both groups) in all dimensions with significantly higher scores in 'Peer Support' (p = 0.013), 'Making a Difference' (p = 0.011), 'About Me' (p = 0.027) and 'Generally Happy' (p = 0.011). There was no difference in the scores between non-HPS and HPS parents. The HPS teachers reported significantly higher scores in 'Health Policies' (p = 0.023), 'Social Environment' (p = 0.049), 'School Community Relations' (p = 0.048), 'Personal Skills Building' (p = 0.008) and 'Partnership & Health Services' (p = 0.047). The secondary HPS students and teachers reported significantly higher resilience scores than those of non-HPS. This study shows that the HSA scheme under WHO has the potential to exert positive changes in students and teachers and the concept of HPS is effective in building resilience among major school stakeholders.

[Pressurized solvent extraction in quality control of Chinese herb].

Pressurized solvent extraction (PSE) is a new extraction technology which has been developed in recent years and widely used as sample analysis in environmental, food and pharmaceutical fields. Extraction technique is a key technology in quality control of Chinese herb. Conventional extraction techniques have been a bottleneck of blocking the development of quality control of Chinese herb. This article attempts to review the basic principle, methods, apparatus and main characteristics of PSE and its applications to quality control of Chinese herb.
