Spatial-temporal distribution, source identification, risk assessment and water quality assessment of trace elements in the surface water of typical tributary in Yangtze River delta, China

He, Miao; Liu, Guijian; Li, Yongli; Zhou, Li; Arif, Muhammad; Liu, Yuan
As China's first cross-province ecological compensation mechanism pilot area in the hinterland of the Yangtze River Delta, Xin'an River has been hotspot in the study of rational utilization of ecological resources, and the functional value of its ecosystem services has been widely concerned. As an important tributary of the upper reaches of Xin'an River, Fengle River may affect the whole basin. The spatial-temporal distributions, occurrence, water quality and risk assessment of trace elements were studied in Fengle River in three seasons. High element concentrations were found in the downstream. Traceability models results showed that the major sources of trace elements were related to different human activities. The water quality was worse downstream in the wet season, and was more suitable for irrigation in the dry season. Risk assessment results showed that Zn, Cu, Mn, Co, and As were able to pose the risk to the ecological environment and human.

"My Hands Are Tied": Abortion Restrictions and Providers' Experiences in Religious and Nonreligious Health Care Systems

Hasselbacher, Lee A; Hebert, Luciana E; Liu, Yuan; Stulberg, Debra B
CONTEXT:Abortion is generally prohibited in Catholic hospitals, but less is known about abortion restrictions in other religiously affiliated health care facilities. As religiously affiliated health systems expand in the United States, it is important to understand how religious restrictions affect the practices of providers who treat pregnant patients. METHODS:From September 2016 to May 2018, in-depth interviews were conducted with 31 key informants (clinical providers, ethicists, chaplains and health system administrators) with experience working in secular, Protestant or Catholic health care systems in Illinois. A thematic content approach was used to identify themes related to participants' experiences with abortion policies, the role of ethics committees, the impact on patient care and conflicts with hospital policies. RESULTS:Few limitations on abortion were reported in secular hospitals, while Catholic hospitals prohibited most abortions, and a Protestant-affiliated system banned abortions deemed "elective." Religiously affiliated hospitals allowed abortions in specific cases, if approved through an ethics consultation. Interpretation of system-wide policies varied by hospital, with some indication that institutional discomfort with abortion influenced policy as much as religious teachings did. Providers constrained by religious restrictions referred or transferred patients desiring abortion, including for pregnancy complications, with those in Protestant hospitals having more latitude to directly refer such patients. As a result of religiously influenced policies, patients could encounter delays, financial obstacles, restrictions on treatment and stigmatization. CONCLUSIONS:Patients seeking abortion or presenting with pregnancy complications at Catholic and Protestant hospitals may encounter more delays and fewer treatment options than they would at secular hospitals. More research is needed to better understand the implications for women's access to reproductive health care.

"Am I Going to Be in Trouble for What I'm Doing?": Providing Contraceptive Care in Religious Health Care Systems

Liu, Yuan; Hebert, Luciana E; Hasselbacher, Lee A; Stulberg, Debra B
CONTEXT:Catholic systems control a growing share of health care in the United States. Because patients seeking contraceptives in Catholic facilities face doctrinal restrictions that may affect access to and quality of care, it is important to understand whether and how providers work within and around institutional policies regarding contraception. METHODS:In 2016-2018, in-depth interviews were conducted in Illinois with 28 key informants-including providers (obstetrician-gynecologists, other physicians, nurse-midwives) and nonclinical professionals (ethicists, administrators, chaplains)-who had experience in secular, Protestant or Catholic health care systems. Interviews addressed multiple aspects of reproductive care and hospital and system policy. A thematic content approach was used to identify themes related to participants' experiences with and perspectives on contraceptive care. RESULTS:While respondents working in secular and Protestant systems reported few limitations on contraceptive care, those working in Catholic systems reported multiple barriers. Providers who had worked in Catholic systems described variable institutional policies and enforcement practices, ranging from verbal admonishments to lease agreements prohibiting contraceptive provision in secular clinics on church-owned land. Despite these restrictions, patients' needs motivated many providers to utilize work-arounds; some providers reported having been pressured or directly instructed to document false diagnoses in patients' medical records. Interviewees described how these obstacles burdened patients, especially those with social and financial constraints, and resulted in delayed or lower quality care. CONCLUSIONS:Providers working in Catholic hospitals are limited in their ability to serve women of reproductive age. Work-arounds intended to circumvent restrictions may inadvertently stigmatize contraception and negatively affect patient care.

Patient factors associated with lung transplant referral and waitlist for patients with cystic fibrosis and pulmonary fibrosis

Liu, Yuan; Vela, Monica; Rudakevych, Tanya; Wigfield, Christopher; Garrity, Edward; Saunders, Milda R
BACKGROUND:Since 2005, the Lung Allocation Score (LAS) has prioritized patient benefit and post-transplant survival, reducing waitlist to transplant time to <200 days and decreasing mortality on the waitlist. A current challenge is the wait for the waitlist-the time between the patient's transplant-eligible diagnosis and waitlist registration. METHODS:] percent of predicted, body mass index, depression/anxiety, alcohol/substance misuse, absolute/relative contraindications) factors influenced referral and waitlist registration. We conducted a retrospective cohort study through chart review of hospitalized patients on the University of Chicago general medicine service from 2006 to 2014 who met transplant-eligible criteria and ICD-9 billing codes for cystic fibrosis (CF) and pulmonary fibrosis (PF). We analyzed the times from transplant eligibility to referral, work-up and waitlisting using Kaplan-Meier curves and log-rank tests. RESULTS:Overall, the referral rate for transplant-eligible patients was 64%. Of those referred, approximately 36% reach the lung transplant waitlist. Referred CF patients were significantly more likely to reach the transplant waitlist than PF patients (CF 60% vs PF 22%, p < 0.05). In addition, CF patients had a shorter wait from transplant eligibility to waitlist than PF patients (329 vs 2,369 days, respectively [25th percentile], p < 0.05). Patients with PF and CF both faced delays from eligibility to referral and waitlist. CONCLUSIONS:Quality improvement efforts are needed to better identify and refer appropriate patients for lung transplant evaluation. Targeted interventions may facilitate more efficient evaluation completion and waitlist appearance.
