Community Health Impacts From Natural Gas Pipeline Compressor Stations.

Compressor stations maintain pressure along natural gas pipelines to sustain gas flow. Unfortunately, they present human health concerns as they release chemical pollutants into the air, sometimes at levels higher than national air quality standards. Further, compressor stations are often placed in rural areas with higher levels of poverty and/or minority populations, contributing to environmental justice concerns. In this paper we investigate what chemical pollutants are emitted by compressor stations, the impacts of emitted pollutants on human health, and local community impacts. Based on the information gained from these examinations, we provide the following policy recommendations with the goal of minimizing harm to those affected by natural gas compressor stations: the Environmental Protection Agency (EPA) and relevant state agencies must increase air quality monitoring and data transparency; the EPA should direct more resources to monitoring programs specifically at compressor stations; the EPA should provide free indoor air quality monitoring to homes near compressor stations; the EPA needs to adjust its National Ambient Air Quality Standards to better protect communities and assess cumulative impacts; and decision-makers at all levels must pursue meaningful involvement from potentially affected communities. We find there is substantial evidence of negative impacts to strongly support these recommendations.

Discordance and concordance on perception of quality care at end of life between older patients, caregivers and clinicians: a scoping review.

BACKGROUND: This scoping review aimed to investigate the presence of discordance or concordance in the perceptions of end-of-life (EOL) care quality between consumers (i.e. patients aged over 60 in their last years of life and/or their informal caregivers) and clinicians, to inform further improvements in end-of-life care service delivery. METHODS: A scoping review of qualitative and quantitative studies was systematically undertaken by searching for English language publications in MEDLINE database and manual reference search of eligible articles. Thematic analysis was employed to identify and extract common concordance and discordance themes leading to the development of analytical constructs. Articles were eligible for inclusion if they reported on consumers' (i.e. older patients aged 60 + years in their final years of life and/or their informal caregivers) and clinicians' (doctors, nurses, social workers, etc.) perspectives on quality of medical, surgical or palliative/supportive care administered to older adults in the last year of life across all healthcare settings. RESULTS: Of the 2736 articles screened, 21 articles were included. Four themes identified concordance between consumers' and clinicians' perceptions of care quality: holistic patient care; coordinated care that facilitated EOL; the role of family at EOL; and impact of prognostic uncertainty on care planning. Three themes emerged for discordance of perceptions: understanding the patient needs at EOL; capacity of healthcare system/providers to accommodate family needs; and knowledge and communication of active or palliative care at EOL. CONCLUSIONS: While progress has been made on promoting patient autonomy and respecting the family role in representing patient's best interest, gaps remain in terms of care coordination, communication of prognosis, public understanding of the meaning of goals of care including de-escalation of management and enactment of advance care directives by clinicians for people with diminished decision capacity. Public understanding of the meaning of "comfort" care and the need to prevent over-treatment are essential for their satisfaction with care and their ability to embrace the concept of a good death.

Challenges and facilitators in delivering optimal care at the End of Life for older patients: a scoping review on the clinicians' perspective.

The concepts and elements determining quality of care at the End of Life may vary across professional groups but there is consensus that high-quality care at the End of Life is beneficial for the patient, families, health systems and society at large. This scoping review aimed to elucidate gaps in the delivery of this specific type of care in older people from the clinicians' perspective, and to identify potential solutions to both improve this care and promote work satisfaction by the involved clinicians. Twelve studies published since 2010 with data from 18 countries identified four major gaps: (1) Core clinical competencies; (2) Shared decision-making; (3) Health care system, environmental context, and resources; and (4) Organisational leadership, culture and legislation. Multiple suggestions for staff communications training, multidisciplinary mentoring, and advance care planning alignment with patient wishes were identified. However, a clear picture arose of consistently unmet needs that have been previously highlighted in research for more than a decade. This indicates poor uptake of previous recommendations and highlights the difficulties in changing the service culture to ensure provision of optimal services at the End of Life. Future investigations on the reasons for poor uptake and identification of effective approaches to execute the agreed recommendations are warranted.

Serum citrulline levels correlate with enteral tolerance and bowel length in infants with short bowel syndrome.

OBJECTIVE: To determine if serum levels of CIT (a nonprotein amino acid synthesized by the intestine) correlate with total parenteral nutrition (PN)-independence in children with short bowel syndrome (SBS). STUDY DESIGN: We prospectively obtained serum amino acid profiles over a 24-month interval from all infants with SBS 3 weeks to 4 years of age. Remaining small intestine length was recorded at surgery, and percent enteral calories tolerated (enteral calories divided by enteral plus parenteral calories x 100) was determined in 24 infants with SBS and 21 age-matched controls (blood drawn for non-gastrointestinal symptoms). RESULTS: Mean CIT for controls was 31 +/- 2 micromol/L. In patients with SBS (n = 24), serum CIT correlated linearly with percent enteral calories (R = 0.85; P <.001) and with bowel length (R = 0.47; P < or =.03). CIT level in patients with SBS weaned off PN was 30 +/- 2 micromol/L; in those subsequently weaned off PN, 20 +/- 2 micromol/L; and in those who would remain PN-dependent, 11 +/- 2 micromol/L ( P < or =.01). Serum CIT > or =19 micromol/L had 94% sensitivity and 67% specificity for being off or coming off total PN. CONCLUSIONS: Serum CIT level >19 micromol/L in children with SBS is associated with development of enteral tolerance and may be a useful predictive test.
