An Exploratory Study of Air Quality Near Natural Gas Operations

This exploratory study was designed to assess air quality in a rural western Colorado area where residences and gas wells co-exist. Sampling was conducted before, during, and after drilling and hydraulic fracturing of a new natural gas well pad. Weekly air sampling for 1 year revealed that the number of non-methane hydrocarbons (NMHCs) and their concentrations were highest during the initial drilling phase and did not increase during hydraulic fracturing in this closed-loop system. Methylene chloride, a toxic solvent not reported in products used in drilling or hydraulic fracturing, was detected 73% of the time; several times in high concentrations. A literature search of the health effects of the NMHCs revealed that many had multiple health effects, including 30 that affect the endocrine system, which is susceptible to chemical impacts at very low concentrations, far less than government safety standards. Selected polycyclic aromatic hydrocarbons (PAHs) were at concentrations greater than those at which prenatally exposed children in urban studies had lower developmental and IQ scores. The human and environmental health impacts of the NMHCs, which are ozone precursors, should be examined further given that the natural gas industry is now operating in close proximity to human residences and public lands.     

Anemia and Dental Caries in Pregnant Women: a Prospective Cohort Study

The objective was to evaluate the effect of anemia during pregnancy on the risk of dental caries development in pregnant women. A prospective cohort including a sample of pregnant women in a prenatal care unit of São Luís, Brazil, was done. The incidence of dental caries during pregnancy, according to Nyvad’s criteria, was the outcome. The main independent variables were serum iron, ferritin, hemoglobin, erythrocyte, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW). Pregnant women (n = 121) were evaluated at two moments: up to 16th week of gestational age (T1) and in the last trimester of pregnancy (T2). Crude and adjusted associations were estimated by the incidence ratio risk (IRR) and respective 95% confidence intervals (95%CI). After adjustment, higher serum concentrations of ferritin (IRR = 0.97, 95%CI 0.95–0.99) in T1, and Fe (IRR = 0.99, 95%CI 0.98–0.99), ferritin (IRR = 0.99, 95%CI 0.98–0.99), erythrocyte (IRR = 0.71, 95%CI 0.50–0.99), hemoglobin (IRR = 0.84, 95%CI 0.73–0.96), hematocrit (IRR = 0.93, 95%CI 0.88–0.98), MCV (IRR = 0.91, 95%CI 0.86–0.96), and MCH (IRR = 0.83, 95%CI 0.74–0.93) in T2, were associated with fewer incidence of dental caries in pregnant women. Iron deficiency anemia during pregnancy is a risk factor for the incidence of dental caries in these women.     

The Relationship between Body Weight and Health Care among German Women

Objective: To investigate the relationship between body weight and the use of health care services among women from southern Germany. Research Methods and Procedures: Data were drawn from the 1994 to 1995 Monitoring of Trends and Determinants in Cardiovascular Disease Augsburg survey, covering a population‐representative sample of women 25 to 74 years old (n = 2301). Logistic regression models were used to calculate odds ratios (ORs) for the use of medical services by women with overweight (BMI 25.0 to 29.9 kg/m²) or obesity (BMI ≥ 30 kg/m²) in comparison with normal‐weight women (BMI < 25.0 kg/m²). Results: In multivariable analysis, obese women 50 to 74 years old were more likely than normal‐weight women to delay cancer screening procedures, such as manual breast examination and Papanicolaou smear (OR 0.52, 95% confidence interval 0.37 to 0.74) in the previous 12 months. However, the relationship between obesity and cancer screening was not found to be significant in 25‐ to 49‐year‐old women (OR 0.92, 95% confidence interval 0.62 to 1.36). Neither in the 25‐ to 49‐year‐old age group nor in the 50‐ to 74‐year‐old age group were independent relationships between higher body weight and total physician visits, hospitalizations, or medication use observed. Discussion: Obese women tended to use medical services with greater frequency due to obesity‐related diseases. However, postmenopausal women with a BMI ≥ 30 kg/m² were more likely to delay routine cancer screening, putting them at a greater risk for death from breast, cervical, and endometrial cancer. Thus, obese postmenopausal women should be targeted for increased screening.     

Determinants of the Relationship between Cytokine Production in Pregnant Women and Their Infants

Exposure to environmental factors during fetal life and infancy is thought to play an important role in the early development of innate and adaptive immunity. The immunological relationship between mother and infant and the effect that environmental exposures have during pregnancy and early childhood have not been studied extensively. Here the production of cytokines was measured in 146 pairs of mothers and their 2- month-old infants. The effect of place of residence, socio-economic variables, parasitic infections as well as maternal and child characteristics on measured cytokine production was determined. Mothers producing high levels of IL-10, IFN-γ and IL-5 were more likely to have infants who also produced high levels of these cytokines either spontaneously (OR 2.6(95%CI 1.2–5.4), OR 2.9(CI 1.3–6.6), OR 11.2(CI 4.6–27.2), respectively) or in response to PHA (IL-10: OR 3.0(CI 1.4–6.6), IFN-γ: OR 2.0(CI 1.0–4.2), respectively) even after adjustment for potential confounding variables. This was not the case for TNF-α. In response to LPS, place of residence was a strong determinant of infant IL-10 (OR 0.2(CI 0.1–0.9)) and TNF-α (OR 0.3(CI 0.1–0.9)) production. Maternal protozoan infections was independently associated with reduced infant IL10 in response to PHA and to LPS as well as reduced TNF-α and IFN-γ in response to PHA. These results indicate strong relationship between maternal and infant''s cellular immune responses even after taking into account many environmental influences that could affect infant''s response directly or indirectly through uterine microenvironment. However, place of residence and intestinal infections may still directly affect the immune responses of the infant. Taken together, the study provides evidence for imprinted cytokine responses of an infant which may have implications for their reaction to incoming antigens, warranting further investigation into the role that genetics or epigenetics play in shaping the cytokine response by an infant to self or external antigens.

Companion Animals in Obituaries: An Exploratory Study

ABSTRACT

The benefits of human–animal interaction have been discussed extensively in the literature. In this paper we take a slightly different strategy in documenting that some humans acknowledge the importance of pets by actually referring to them in human obituaries. We begin with a brief overview of the human obituary, followed by the potential for pets as fictive kin to be named as survivors in obituaries. A bi-national, exploratory, content analysis of companion animal (CA)-related content in published newspaper obituaries is reported. The two criteria for inclusion were that a pet or pet survivors be named in the obituary or that donations be made to a pet-related charity. Of the 11,818 obituaries in three newspapers over a three-month period, 260 (2.2%) met one or both of these criteria. Five themes emerged within obituaries containing CA data. First, the word “pet” was rarely used. CAs were typically listed as survivors along with human family members. Second, terms of endearment were consistently used to describe animal companions left behind. Third, some family members, who likely crafted these last statements about their loved ones, engaged in a personification of (and projections onto) the animals left behind. Fourth, there was variation in the roles played by each person with their animal companion. And fifth, donations were made to a wide variety of animal charities. The possibility of CAs as fictive kin is explored, in addition to a call for further study.     

The Doctor-Patient Relationship: A Survey of Attitudes and Practices of Doctors in Singapore

This article reports the results of a survey, by mailed questionnaire, of the attitudes, values and practices of doctors in Singapore with respect to the doctor-patient relationship. Questionnaires were sent to a random sample of 475 doctors (261 general practitioners and 214 medical specialists), out of which 249 (52.4%) valid responses were completed and returned. The survey is the first of its kind in Singapore. Questions were framed around issues of medical paternalism, consent and patient autonomy. As the doctors were exposed to Western ethical concepts in their training, we were not surprised to find that they would mostly allow patients some say in decision-making and keep patients reasonably informed. In respecting patient autonomy, they would usually seek to influence patient choice by persuasion. However, the residual 'Asian-ness' of doctors in Singapore gives rise to some inconsistencies between values and practices. Many doctors still believe that a number of their patients are incapable of rational choice. There is some lack of openness in telling patients the whole truth. When patients choose to refuse treatment, many doctors are prepared to involve family members in making a consensus decision.
Doctors were also asked how they made ethical judgements in the face of dilemmas, and how they would like disputes with patients to be resolved. By and large, the doctors prefer to make their own judgements rather than to rely on rules. They also wish to keep the law courts out of disputes with patients, preferring less public ways of settling disputes.     

An Exploratory Study into Objective and Reported Characteristics of Neuropathic Pain in Women with Chronic Pelvic Pain

Chronic pelvic pain (CPP) affects 5.7–26.6% women worldwide. 55% have no obvious pathology and 40% have associated endometriosis. Neuropathic pain (NeP) is pain arising as a consequence of a lesion/disease affecting the somatosensory system. The prevalence of NeP in women with CPP is not known. The diagnosis of NeP is challenging because there is no gold-standard assessment. Questionnaires have been used in the clinical setting to diagnose NeP in other chronic pain conditions and quantitative sensory testing (QST) has been used in a research setting to identify abnormal sensory function. We aimed to determine if women with chronic pelvic pain (CPP) have a neuropathic pain (NeP) component to their painful symptoms and how this is best assessed. We performed an exploratory prospective cohort study of 72 pre-menopausal women with a diagnosis of CPP. They underwent a clinician completed questionnaire (DN4) and completed the S-LANSS and PainDETECT^™ questionnaires. Additionally QST testing was performed by a clinician. They also completed a patient acceptability questionnaire. Clinical features of NeP were identified by both questionnaires and QST. Of the women who were NeP positive, 56%, 35% and 26% were identified by the S-LANSS, DN4 and PainDETECT^™ respectively. When NeP was identified by questionnaire, the associated laparoscopy findings were similar irrespective of which questionnaire was used. No subject had entirely unchanged QST parameters. There were distinct loss and gain subgroups, as well as mixed alteration in function, but this was not necessarily clinically significant in all patients. 80% of patients were confident that questionnaires could diagnose NeP, and 90% found them easy to complete. Early identification of NeP in women with CPP with a simple questionnaire could facilitate targeted therapy with neuromodulators, which are cheap, readily available, and have good safety profiles. This approach could prevent unnecessary or fertility-compromising surgery and prolonged treatment with hormones.     

The Association between Nonylphenols and Sexual Hormones Levels among Pregnant Women: A Cohort Study in Taiwan

Background

Nonylphenol (NP) has been proven as an endocrine disrupter and had the ability to interfere with the endocrine system. Though the health effects of NP on pregnant women and their fetuses are sustained, these negative associations related to the mechanisms of regulation for estrogen during pregnancy need to be further clarified. The objective of this study is to explore the association between maternal NP and hormonal levels, such as estradiol, testosterone, luteinizing hormone (LH) and follicle stimulating hormone (FSH), and progesterone.

Methods

A pregnant women cohort was established in North Taiwan between March and December 2010. Maternal urine and blood samples from the first, second, and third trimesters of gestation were collected. Urinary NP concentration was measured by high-performance liquid chromatography coupled with fluorescent detection. A mixed-effects model using a generalised estimating equation (GEE) was applied to assess the associations between maternal NP concentration and plasma hormones throughout the three trimesters.

Results

In total, 162 singleton pregnant women completed this study through delivery. The geometric mean of creatinine-adjusted urinary NP concentrations were 4.27, 4.21, and 4.10 µg/g cre. in the first, second, and third trimesters respectively. A natural log-transformation of urinary NP concentrations were significantly associated with LH in the GEE model (β = −0.23 mIU/ml, p<0.01).

Conclusion

This perspective cohort study demonstrates that negative association occurs between maternal NP exposure and plasma LH levels. The estrogen-mimic effect of NP might influence the negative feedback on LH during pregnancy.     

The Effects of Face Masks on the Doctor-Patient Relationship in Orthopaedics

BackgroundSince the onset of the COVID-19 pandemic, the widespread use of face masks has grown exponentially. There is limited data highlighting the patient perception of face mask use during this pandemic, specifically in orthopaedic clinics. The purpose of this study was to determine the patient’s perception of the implementation of face masks in the orthopaedic clinic during a period of mask mandates and if this change impacted the success of their interactions with physicians. The secondary aim includes measures of patient satisfaction such as the ability to understand conversation and communicate effectively with the physician.MethodsParticipants were recruited on the day of their appointment at our institution’s orthopaedic clinic and provided with instructions via email. The online, anonymous survey included the CARE questionnaire - a tool to examine patient satisfaction by assessing perception of empathy and was conducted using Qualtrics.ResultsDoes patient preference to have their physician wear a face mask impact the success of their interactions with physicians? Overall, the use of face masks by physicians did not negatively impact patient encounters. CARE scores for patients who preferred masks (37.2) were similar to those who preferred their physician did not wear a mask (37.5). Is patient satisfaction affected by the use of face masks in the orthopaedic clinic? Patients who preferred that their doctor wear a face mask stated that it had no negative impact on the effect of communication or conversation with the physician. Other factors such as how well the patients knew the physician and patient gender had a greater impact on the CARE score than masks did.ConclusionOur study determined that the preference of face masks by patients does not impact the success of their interactions with physicians using the CARE score. The findings of this study are valuable in informing orthopaedic physicians about patient attitudes towards mask use and could influence decision making for not only the COVID-19 pandemic, but also future infectious outbreaks that may arise.

Caregiver Evaluation of the Quality of End-Of-Life Care (CEQUEL) Scale: The Caregiver's Perception of Patient Care Near Death

Purpose

End-of-life (EOL) measures are limited in capturing caregiver assessment of the quality of EOL care. Because none include caregiver perception of patient suffering or prolongation of death, we sought to develop and validate the Caregiver Evaluation of Quality of End-of-Life Care (CEQUEL) scale to include these dimensions of caregiver-perceived quality of EOL care.

Patients and Methods

Data were derived from Coping with Cancer (CwC), a multisite, prospective, longitudinal study of advanced cancer patients and their caregivers (N = 275 dyads). Caregivers were assessed before and after patient deaths. CEQUEL''s factor structure was examined; reliability was evaluated using Cronbach''s α, and convergent validity by the strength of associations between CEQUEL scores and key EOL outcomes.

Results

Factor analysis revealed four distinct factors: Prolongation of Death, Perceived Suffering, Shared Decision-Making, and Preparation for the Death. Each item loaded strongly on only a single factor. The 13-item CEQUEL and its subscales showed moderate to acceptable Cronbach''s α (range: 0.52–0.78). 53% of caregivers reported patients suffering more than expected. Higher CEQUEL scores were positively associated with therapeutic alliance (ρ = .13; p≤.05) and hospice enrollment (z = −2.09; p≤.05), and negatively associated with bereaved caregiver regret (ρ = −.36, p≤.001) and a diagnosis of Posttraumatic Stress Disorder (z = −2.06; p≤.05).

Conclusion

CEQUEL is a brief, valid measure of quality of EOL care from the caregiver''s perspective. It is the first scale to include perceived suffering and prolongation of death. If validated in future work, it may prove a useful quality indicator for the delivery of EOL care and a risk indicator for poor bereavement adjustment.     

Representation of Women and Pregnant Women in HIV Research: A Limited Systematic Review

Background

HIV-related outcomes may be affected by biological sex and by pregnancy. Including women in general and pregnant women in particular in HIV-related research is important for generalizability of findings.

Objective

To characterize representation of pregnant and non-pregnant women in HIV-related research conducted in general populations.

Data Sources

All HIV-related articles published in fifteen journals from January to March of 2011. We selected the top five journals by 2010 impact factor, in internal medicine, infectious diseases, and HIV/AIDS.

Study Eligibility Criteria

HIV-related studies reporting original research on questions applicable to both men and women of reproductive age were considered; studies were excluded if they did not include individual-level patient data.

Study appraisal and synthesis methods.

Articles were doubly reviewed and abstracted; discrepancies were resolved through consensus. We recorded proportion of female study participants, whether pregnant women were included or excluded, and other key factors.

Results

In total, 2014 articles were published during this period. After screening, 259 articles were included as original HIV-related research reporting individual-level data; of these, 226 were determined to be articles relevant to both men and women of reproductive age. In these articles, women were adequately represented within geographic region. The vast majority of published articles, 183/226 (81%), did not mention pregnancy (or related issues); still fewer included pregnant women (n=33), reported numbers of pregnant women (n=19), or analyzed using pregnancy status (n=9).

Limitations

Data were missing for some key variables, including pregnancy. The time period over which published works were evaluated was relatively short.

Conclusions and implications of key findings.

The under-reporting and inattention to pregnancy in the HIV literature may reduce policy-makers’ ability to set evidence-based policy around HIV/AIDS care for pregnant women and women of child-bearing age.     

The Bidirectional Relationship between Quality of Life and Eating Disorder Symptoms: A 9-Year Community-Based Study of Australian Women

Objective

Studies that have investigated quality of life (QoL) in eating disorders (EDs) have been focussed on the impact of the ED on QoL and little is known regarding the possible reciprocal impact of QoL on EDs. The aim of this study was to provide a first-time investigation of possible bidirectional relationships between EDs and both health-related QoL (HRQoL) and psychological distress (PD).

Method

Structural equation modeling was applied to longitudinal data collected from a community sample of Australian women (N = 828) surveyed at baseline, five annual follow-ups, and again after nine years. Participants reported height and weight (from which body mass index, BMI, was calculated) and completed measures of ED symptoms (Eating Disorder Examination Questionnaire), HRQoL (12-item Medical Outcomes Study Short Form), and PD (Kessler Psychological Distress Scale).

Results

Overall, evidence was found for a bidirectional relationship, whereby ED symptoms predicted reduced HRQoL and greater PD over time, while lower levels of HRQoL and greater PD in turn predicted increased levels of ED symptoms. These relationships were stable, observable within 12 months, and remained observable over a time period of at least four years. However, also observed were some inconsistent findings where ED symptoms predicted a short term (one year) improvement in mental HRQoL. This short term boost was not sustained at longer follow-ups.

Conclusions

Not only do ED symptoms impact on HRQoL and PD, but perceived poor HRQoL and PD also contribute to ED symptom development or exacerbation. This supports a movement away from symptom-centric approaches whereby HRQoL is conceptualized as a passive outcome expected to be rectified by addressing ED symptoms. Improvement in QoL and PD might rather be viewed as targets to be pursued in their own right under broader approaches in the treatment of EDs.

Animal Hoarding in Victoria,Australia: An Exploratory Study

Animal hoarding not only presents significant welfare issues for the animals involved, but also for the hoarders and people in the surrounding community. Existing studies on the issue have primarily been undertaken in the USA and little is known about animal hoarding in other countries, including Australia. It has been estimated that the per-capita prevalence of animal hoarding in Victoria, Australia, is similar to that in the USA, but in order to design effective intervention strategies, the extent of the issue and its characteristics need to be identified. This study analyzes data from 22 recent cases of animal hoarding from a number of agencies in Victoria. The demographics and living conditions of animal hoarders in Victoria and the USA were found to be similar. In contrast, the animals involved in hoarding cases in Victoria were in a better condition than the animals in the USA, with behavioral issues being the leading animal welfare concern in Australia. Behavioral problems resulted in euthanasia of the animals in 45% of the cases studied. All of the agencies included in this study call for a greater involvement or support from human mental health services to fully address the root of the problem. The information from this study can be used to help identify groups at risk to develop effective and appropriate means of prevention of, and intervention in, animal hoarding cases.
