Longitudinal associations of the alternative healthy eating index with coronary artery calcification and pericardial adiposity in US adults with and without type 1 diabetes.

BACKGROUND AND AIM: Long-term associations between the alternative healthy eating index (AHEI) score and two predictive indicators for CVD, pericardial adipose tissue (PAT) and coronary artery calcification (CAC) volume, are lacking. Our study aims to investigate the longitudinal associations of the AHEI score with measures of CAC and PAT in adults with and without type 1 diabetes (T1D). METHODS AND RESULTS: The prospective Coronary Artery Calcification in T1D (CACTI) study included 652 people with T1D and 764 people without diabetes (non-DM) (19-56 years old) and was conducted in 2000-2002, 2003-2004, and 2006-2007. At each visit, food frequency questionnaires were collected and PAT and CAC were measured using electron beam computed tomography. Two variables were used for CAC analyses: a continuous variable for the square-root tranformed volume (SRV) for each visit and a second variable identified CAC progression from baseline to visit 3. Mixed effect models and a logistic regression model were used to conduct statistical analyses. A one-point increase in the AHEI score was significantly associated with a -0.12 cm3 (95% CI: -0.17, -0.08; p-value<0.0001) decrease in PAT volume in combined analyses, a -0.16 cm3 (95% CI: -0.22, -0.09; p-value<0.0001) decrease in the non-DM group, a marginally significant -0.07 cm3 (95% CI: -0.14, 0.002; p-value = 0.0571) decrease in the T1D group, and was not associated with either CAC outcome. CONCLUSION: The AHEI score is inversely associated with PAT; the association revealed greater magnitude of PAT reduction in the non-DM group. The AHEI score did not associate with CAC progression.

Food and Housing Insecurity in Nevada During the COVID-19 Pandemic.

The COVID-19 pandemic intensified concerns regarding food and housing insecurity in the United States, particularly among vulnerable populations. After the pandemic prompted a shutdown of nonessential businesses in Nevada, unemployment rose dramatically as the gaming, tourism, and hospitality industries struggled. This study analyzed the results of two telephone surveys of Nevada adults' experiences in 2020 (n = 1000) and 2021 (n = 1002). The results demonstrate between 2020 and 2021 an 8.24 percentage point decline in food insecurity (FI) from 30.2% to 21.96% and a 12.58 percentage point increase in housing insecurity (HI) from 12.27% to 24.85%. Age, disability status, and certain categories of race/ethnicity and income were associated with both HI and FI in 2020, but disability was no longer significant in 2021. Instead, spouse/partner-status, living with children ≤ 18-years-old and receipt of SNAP benefits were significantly associated with FI in 2021. In particular, health status became a significant factor of both HI and FI. People of color experienced FI disparities compared to Whites. Asians/Hawaiians/Pacific Islanders were 3.22 times (95% CI 1.51, 6.86) more likely to experience FI in 2021 than Whites. A matched, longitudinal analysis also revealed that Whites experienced a significant 9.1 percentage point estimated decline in the probability of FI between 2020 and 2021. However, the reduction among non-White participants was statistically insignificant at 2.5 percentage points. Results indicate the importance of supporting the food and housing needs of people of color and individuals with disabilities. Further research should especially investigate the comparative FI rate among Asians/Hawaiians/Pacific Islanders in 2021 and offer solutions to the soaring prevalence of housing insecurity.

Longitudinal Associations of Healthy Dietary Pattern Scores with Coronary Artery Calcification and Pericardial Adiposity in United States Adults with and without Type 1 Diabetes.

BACKGROUND: Pericardial adipose tissue volume (PAT) and coronary artery calcification (CAC) are prognostic indicators for future cardiovascular events; however, no studies have assessed the long-term associations of adherence to dietary patterns (DPs) with PAT and CAC in adults with and without type 1 diabetes (T1D). OBJECTIVES: We investigated the longitudinal associations of the Mediterranean Diet (MedDiet) and Dietary Approaches to Stop Hypertension (DASH) diet with PAT and CAC progression in adults with and without T1D. METHODS: The Coronary Artery Calcification in Type 1 Diabetes (CACTI) study is a population-based, prospective study of 652 T1D and 764 nondiabetic mellitus (nonDM) (19-56 y) participants that began in 2000-2002 with follow-up visits in 2003-2004 and 2006-2007. At each visit, food frequency questionnaires were collected and used to develop adherence scores for the MedDiet and DASH diets. PAT and CAC were measured at each visit using electron beam computed tomography. CAC progression was defined as a ≥2.5 mm square root-transformed volume. Mixed effect models were used to conduct statistical analyses. RESULTS: Combined models found a significant-0.09 cm3 (95% CI: -0.14, -0.03; P = 0.0027) inverse association in PAT for every 1-point increase in the MedDiet score and a significant-0.26 cm3 (95% CI: -0.38, -0.14; P < 0.0001) inverse association in PAT for every 1-point increase in the DASH score. In combined models, the DPs were not significantly associated with lower odds of CAC progression; however, both DPs had significant interactions by diabetes status for CAC. Only the DASH diet was associated with lower odds of CAC progression in the nonDM group (OR: 0.96; 95% CI: 0.93, 0.99; P = 0.0224). CONCLUSIONS: These data suggest that the DPs are associated with lower PAT, which may reduce future cardiovascular events. The DASH diet may be beneficial for lower odds of CAC progression in those without T1D.

Influence of Simulated Microgravity on Mammary Epithelial Cells Grown as 2D and 3D Cultures.

During space travel, astronauts will experience a unique environment that includes continuous exposure to microgravity and stressful living conditions. Physiological adaptation to this is a challenge and the effect of microgravity on organ development, architecture, and function is not well understood. How microgravity may impact the growth and development of an organ is an important issue, especially as space flight becomes more commonplace. In this work, we sought to address fundamental questions regarding microgravity using mouse mammary epithelial cells in 2D and 3D tissue cultures exposed to simulated microgravity. Mouse mammary HC11 cells contain a higher proportion of stem cells and were also used to investigate how simulated microgravity may impact mammary stem cell populations. In these studies, we exposed mouse mammary epithelial cells to simulated microgravity in 2D and then assayed for changes in cellular characteristics and damage levels. The microgravity treated cells were also cultured in 3D to form acini structures to define if simulated microgravity affects the cells' ability to organize correctly, a quality that is of key importance for mammary organ development. These studies identify changes occurring during exposure to microgravity that impact cellular characteristics such as cell size, cell cycle profiles, and levels of DNA damage. In addition, changes in the percentage of cells revealing various stem cell profiles were observed following simulated microgravity exposure. In summary, this work suggests microgravity may cause aberrant changes in mammary epithelial cells that lead to an increase in cancer risk.

Spatial variations in family planning demand to limit childbearing and the demand satisfied with modern methods in sub-Saharan Africa.

BACKGROUND: There is an increasing demand for family planning to limit childbearing in sub-Saharan Africa (SSA). However, limited studies have quantified the spatial variations. This study examined: (i) the spatial patterns in the demand for family planning to limit childbearing and satisfied with modern methods, and (ii) the correlates of the demand for family planning to limit childbearing satisfied with modern methods in SSA. METHODS: This study analyzed secondary data on 306,080 married/in-union women obtained from Demographic Health Surveys conducted between 2010 and 2019 in 33 sub-Saharan African countries. We conducted exploratory spatial data analysis, with countries as the unit of analysis. We also performed regression analysis to determine the factors associated with demand for family planning to limit childbearing satisfied with modern methods in SSA. RESULTS: The mean percentage of women who demanded for family planning to limit childbearing by country was 20.5% while the mean prevalence of demand for family planning to limit childbearing satisfied with modern methods by country was 46.5%. There was a significant positive global spatial autocorrelation in the demand for family planning to limit childbearing (global Moran's I = 0.3, p = 0.001). The cluster map showed the concentration of cold spots (low-low clusters) in western and central Africa (WCA), while hot spots (high-high clusters) were concentrated in eastern and southern Africa (ESA). Also, the demand for family planning to limit childbearing satisfied with modern methods showed significant positive global spatial autocorrelation (global Moran's I = 0.2, p = 0.004) and concentration of cold spots in WCA. In the final multivariable regression model the joint family planning decision making (ß = 0.34, p < 0.001), and antenatal care (ß = 13.98, p < 0.001) were the significant factors associated with the demand for family planning to limit childbearing satisfied by modern methods. CONCLUSIONS: There are significant spatial variations in the demand for family planning to limit childbearing and the demand satisfied by modern methods, with cold spots concentrated in WCA. Promoting joint decision making by partners and increasing uptake of antenatal care may improve the demand for family planning to limit childbearing satisfied with modern methods.

In sub-Saharan Africa (SSA), studies have shown that the proportion of married women who want to stop having children has been increasing as well as the proportion using modern contraceptive methods among them. These studies also indicated that this proportion of women are higher in certain regions of Africa than the others. To extend these previous findings, we performed geographical analysis to assess how the proportion of married/in-union women who want to stop having children and the ones using modern methods among them differ geographically. Our findings indicated that neighboring countries where the proportion of married/in-union women who want to stop having children was higher than the overall average were concentrated in eastern and southern Africa (ESA), while neighboring countries in which the proportion of married/in-union women who want to stop having children was lower than the overall average were concentrated in western and central Africa (WCA). Similarly, the results also showed that neighboring countries where the proportion of married/in-union women using modern contraceptive methods among those who want to stop having children was lower than the overall average were concentrated in WCA. Our findings suggest that increasing joint decision making on family planning and uptake of antenatal care in SSA may improve the use of modern contraceptive methods among married/in-union women who want to stop childbearing.

Sociodemographic and Biological Factors of Health Disparities of Mothers and Their Very Low Birth-Weight Infants.

BACKGROUND: Black mothers and their very low birth-weight infants in the United States have increased risk of adverse neonatal and maternal health outcomes compared with White mothers and infants. Disparities in adverse birth outcomes associated with sociodemographic factors are difficult to quantify and modify, limiting their usefulness in assessing intervention effects. PURPOSE: To test hypotheses that (1) the biological factors of maternal testosterone and cortisol are associated with sociodemographic factors and (2) both factors are associated with neonatal health and maternal mental health and healthy behaviors between birth and 40 weeks' gestational age. METHODS: We used a descriptive, longitudinal design. Eighty-eight mothers and very low birth-weight neonates were recruited from a tertiary medical center in the United States. Data on sociodemographic factors and neonatal health were collected from medical records. Maternal mental health and healthy behaviors were collected with questionnaires. Maternal salivary testosterone and cortisol levels were measured using enzyme immunoassays. Data were analyzed primarily using general linear and mixed models. RESULTS: High testosterone and/or low cortisol levels were associated with younger age, less education, enrollment in a federal assistance program, being unmarried, being Black, poorer neonatal health, and delayed physical growth. Low cortisol level was related to higher levels of depressive symptoms. Black mothers had fewer healthy behaviors than White mothers. IMPLICATIONS FOR PRACTICE AND RESEARCH: Findings confirm that biological factors are associated with sociodemographic factors, and both are associated with neonatal health and maternal mental health and healthy behaviors. We propose using sociodemographic and biological factors concurrently to identify risk and develop and evaluate ante- and postpartum interventions.Video abstract available athttps://journals.na.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=59.

Associations of dietary patterns and nutrients with coronary artery calcification and pericardial adiposity in a longitudinal study of adults with and without type 1 diabetes.

PURPOSE: To examine the associations of dietary patterns and nutrients with coronary artery calcification (CAC) and pericardial adiposity (PAT) in adults with and without type 1 diabetes. METHODS: We conducted a six-year longitudinal analysis of data from Coronary Artery Calcification in Type 1 Diabetes study [n = 1255; T1D: n = 563; non-DM: n = 692] collected at baseline, year 3 and year 6. Participants completed a validated food frequency questionnaire, a physical examination, and fasting (12 h overnight fast) biochemical analyses. CAC and PAT were measured using electron beam computed tomography. Dietary patterns were identified using factor analysis. Generalized estimating equations were used to examine associations of dietary patterns and nutrients with CAC and PAT in models adjusted for traditional cardiovascular risks. RESULTS: The 'starchy veggies, meats and alcohol pattern' was associated with significantly increased risk of CAC presence in all adjusted models; an increasing trend was observed with CAC progression. Increasing intake of dietary proteins and total fats were also associated with higher risk of the presence and/or progression of CAC in adjusted models (all p < 0.05). PAT was positively associated with dietary total fats, and inversely associated with dietary intakes of saturated fats, omega-3 fats and fiber in models adjusted for age, sex, total calories, time, diabetes status, systolic blood pressure, serum lipids and physical activity. CONCLUSION: Diets high in total fats and proteins, and in meats (processed and red) and alcohol may increase risks of CAC, while saturated fats, omega-3-fats and fiber may be protective against pericardial adiposity as a risk factor for coronary artery disease.

School absenteeism is linked to household food insecurity in school catchment areas in Southern Nevada.

OBJECTIVES: Food security and school attendance are both important for health, well-being and academic performance of children and adolescents. However, their intersection remains underexamined, especially in the USA. The current study considered the association between elementary school-level absenteeism and household food insecurity. DESIGN: The current study linked school-level absenteeism and household food insecurity rates using geographic information system mapping and applied the tobit regression model to examine their association. SETTING: The Clark County, Nevada, public school district - the fifth largest in the USA and in a state with disproportionate food insecurity and chronic school absenteeism rates. PARTICIPANTS: Data consisted of school-level absenteeism rates from 185 elementary schools and census tract-level household food insecurity rates. RESULTS: Average daily attendance rates were lower for schools with catchment areas that had higher average household food insecurity (FI), decreasing by -0·0232 % per 1 % increase in FI rate (P-value = 0·022). They were also significantly associated with most absenteeism risk factors. Average daily attendance rate was negatively associated with Free and Reduced Lunch eligibility percentage (-0·010 per 1 % increase in FI, P-value < 0·001) and Individualized Education Program participation percentage (-0·039 % per 1 % increase in FI, P-value = 0·033), but positively associated with parent-teacher conference participation rate (0·006 % per 1 % increase in FI, P-value = 0·025) and white student percentage (0·011 % per 1 % increase in FI, P-value = 0·022). CONCLUSIONS: The current study suggests a link between household food insecurity and elementary school-level absenteeism. Understanding this link is important for policy and practice because schools are frequent settings for food insecurity mitigation interventions.

Global trends and gaps in research related to latent tuberculosis infection.

BACKGROUND: There is a global commitment to eliminating tuberculosis (TB). It is critical to detect and treat cases of latent TB infection (LTBI), the reservoir of new TB cases. Our study assesses trends in publication of LTBI-related research. METHODS: We used the keywords ("latent tuberculosis" OR "LTBI" OR "latent TB") to search the Web of Science for LTBI-related articles published 1995-2018, then classified the results into three research areas: laboratory sciences, clinical research, and public health. We calculated the proportions of LTBI-related articles in each area to three areas combined, the average rates of LTBI-related to all scientific and TB-related articles, and the average annual percent changes (AAPC) in rates for all countries and for the top 13 countries individually and combined publishing LTBI research. RESULTS: The proportion of LTBI-related articles increased over time in all research areas, with the highest AAPC in laboratory (38.2%/yr), followed by public health (22.9%/yr) and clinical (15.1%/yr). South Africa (rate ratio [RR] = 8.28, 95% CI 5.68 to 12.08) and India (RR = 2.53, 95% CI 1.74 to 3.69) had higher RRs of overall TB-related articles to all articles, but did not outperform the average of the top 13 countries in the RRs of LTBI-related articles to TB-related articles. Italy (RR = 1.95, 95% CI 1.45 to 2.63), Canada (RR = 1.73, 95% CI 1.28 to 2.34), and Spain (RR = 1.53, 95% CI 1.13 to 2.07) had higher RRs of LTBI-related articles to TB-related articles. CONCLUSIONS: High TB burden countries (TB incidence > 100 per 100,000 population) published more overall TB-related research, whereas low TB burden countries showed greater focus on LTBI. Given the potential benefits, high TB burden countries should consider increasing their emphasis on LTBI-related research.

Prenatal Glucocorticoid Treatment Completeness and Steroid Hormonal Levels as Related to Infant and Maternal Health.

This study was conducted to confirm the negative associations between testosterone and cortisol levels and health and developmental outcomes in very low-birth weight (VLBW) infants after controlling for prenatal glucocorticoid (GC) treatment. Seventy-four VLBW infant-mother pairs were recruited from a neonatal intensive care unit in the Southeastern United States. We divided the pairs into the complete (n = 58) and incomplete (n = 16) GC treatment groups. Data on infants and mothers were obtained at birth, 40 weeks' postmenstrual age, and 3 and 6 months' corrected age. Salivary testosterone and cortisol levels of the pairs were determined at 40 weeks' postmenstrual age using enzyme immunoassay. Log-linear and general linear mixed models showed that gestational age and birth weight were lower when testosterone was 1 pg/mL higher. When cortisol was 1 µg/dL higher, technology dependence at discharge was higher and motor development at 6 months was lower. Mothers with complete GC treatment had greater parity and gravida, more prenatal visits, and more medical complications. The study outcomes supported our hypothesis that steroid hormonal levels are more predictive of infant health and development than GC treatment completeness. Single dose of GC treatment might be just as effective as 2 doses, although further study with more subjects would be needed to confirm. As the associations with steroid hormonal levels lasted longer than the GC treatment associations, we recommend confirming the predictive effects of testosterone and cortisol levels after 6 months.

Identifying high risk areas of Zika virus infection by meteorological factors in Colombia.

BACKGROUND: Several Zika virus (ZIKV) outbreaks have occurred since October 2015. Because there is no effective treatment for ZIKV infection, developing an effective surveillance and warning system is currently a high priority to prevent ZIKV infection. Despite Aedes mosquitos having been known to spread ZIKV, the calculation approach is diverse, and only applied to local areas. This study used meteorological measurements to monitor ZIKV infection due to the high correlation between climate change and Aedes mosquitos and the convenience to obtain meteorological data from weather monitoring stations. METHODS: This study applied the Bayesian structured additive regression modeling approach to include spatial interactive terms with meteorological factors and a geospatial function in a zero-inflated Poisson model. The study area contained 32 administrative departments in Colombia from October 2015 to December 2017. Weekly ZIKV infection cases and daily meteorological measurements were collected. Mapping techniques were adopted to visualize spatial findings. A series of model selections determined the best combinations of meteorological factors in the same model. RESULTS: When multiple meteorological factors are considered in the same model, both total rainfall and average temperature can best assess the geographic disparities of ZIKV infection. Meanwhile, a 1-in. increase in rainfall is associated with an increase in the logarithm of relative risk (logRR) of ZIKV infection of at most 1.66 (95% credible interval [CI] = 1.09, 2.15) as well as a 1 °F increase in average temperature is significantly associated with at most 0.79 (95% CI = 0.12, 1.22) increase in the logRR of ZIKV. Moreover, after controlling rainfall and average temperature, an independent geospatial function in the model results in two departments with an excessive ZIKV risk which may be explained by unobserved factors other than total rainfall and average temperature. CONCLUSION: Our study found that meteorological factors are significantly associated with ZIKV infection across departments. The study determined both total rainfall and average temperature as the best meteorological factors to identify high risk departments of ZIKV infection. These findings can help governmental agencies monitor at risk areas according to meteorological measurements, and develop preventions in those at risk areas in priority.

Association of organic solvents and occupational noise on hearing loss and tinnitus among adults in the U.S., 1999-2004.

PURPOSE: Exposure to organic solvents and noise may be causal agents in the development of hearing loss and tinnitus. The objectives of the present study were to examine the association of organic solvents with hearing loss and tinnitus and to assess the interaction of organic solvent and occupational noise exposure on hearing loss and tinnitus. METHODS: A secondary data analysis of data from the National Health and Nutrition Examination Survey and Occupational Information Network (O*NET) among a study population ranging from 1085 to 2471 study participants from 1999 to 2004. Multiple multivariate logistic regression models were used to assess the associations of individual organic solvent exposures as measured by blood biomarkers (1,4-dichlorobenzene, benzene, ethylbenzene, styrene, toluene, o-xylene, and m-/p-xylene) with self-reported hearing loss, audiometrically assessed hearing loss, and self-reported tinnitus. Models were adjusted for age, gender, race/ethnicity, diabetes, non-occupational noise exposure, smoking, and income. Organic solvents found to be statistically significantly associated with the outcome after adjusting for covariates were tested for interaction with occupational noise exposure. RESULTS: Solvent exposure was not statistically significantly associated with self-reported tinnitus. Benzene (OR 1.43, 95% CI 1.15-1.78), ethylbenzene (OR 1.24, 95% CI 1.02-1.50), and toluene (OR 1.27, 95% CI 1.06-1.52) concentrations were statistically significantly associated with increased adjusted odds of high-frequency hearing loss. No statistically significant interaction was observed between these solvents and occupational noise on high-frequency hearing loss. CONCLUSIONS: We found no evidence of an association between organic solvents and tinnitus; however, there was evidence of an association between organic solvent exposure and prevalence of high-frequency hearing loss.

Surveillance on the endemic of Zika virus infection by meteorological factors in Colombia: a population-based spatial and temporal study.

BACKGROUND: Zika virus (ZIKV) infection is a pandemic and a public health emergency. It is transmitted by mosquitoes, primarily the Aedes genus. In light of no treatment currently, it is crucial to develop effective vector control programs to prevent the spread of ZIKV infection earlier when observing possible risk factors, such as weather conditions enhancing mosquito breeding and surviving. METHODS: This study collected daily meteorological measurements and weekly ZIKV infectious cases among 32 departments of Colombia from January 2015-December 2016. This study applied the distributed lag nonlinear model to estimate the association between the number of ZIKA virus infection and meteorological measurements, controlling for spatial and temporal variations. We examined at most three meteorological factors with 20 lags in weeks in the model. RESULTS: Average humidity, total rainfall, and maximum temperature were more predictable of ZIKV infection outbreaks than other meteorological factors. Our models can detect significantly lagged effects of average humidity, total rainfall, and maximum temperature on outbreaks up to 15, 14, and 20 weeks, respectively. The spatial analysis identified 12 departments with a significant threat of ZIKV, and eight of those high-risk departments were located between the Equator and 6°N. The outbreak prediction also performed well in identified high-risk departments. CONCLUSION: Our results demonstrate that meteorological factors could be used for predicting ZIKV epidemics. Building an early warning surveillance system is important for preventing ZIKV infection, particularly in endemic areas.

Gender and posture are significant risk factors to musculoskeletal symptoms during touchscreen tablet computer use.

[Purpose] To investigate the prevalence of neck and shoulder symptoms during the use of tablet computer, and to identify the risk factors associated with these symptoms. [Subjects and Methods] A cross-sectional survey was conducted to study tablet computer usage, posture during use, and neck and shoulder symptoms in 412 participants in a school setting. Significant risk factors for musculoskeletal symptoms during tablet computer use were identified. [Results] Overall prevalence of musculoskeletal symptoms during tablet computer use was 67.9% with greater prevalence of neck symptoms (neck: 84.6%; shoulder/upper extremity: 65.4%). Significant risk factors associated with symptoms during use were: current musculoskeletal symptoms, gender, roles, and postural factors including: sitting without back support, sitting with device in lap, and lying on the side and on the back during tablet computer use. A multivariate analysis further showed that the odds for females to have symptoms were 2.059 times higher than males. [Conclusion] The findings revealed that female gender and other postural factors were significantly associated with musculoskeletal symptoms during the use of tablet computer. Among all postural factors, sitting without back support was identified as the most important risk factor for having musculoskeletal symptoms.

Changes in Sleep With Auricular Point Acupressure for Chronic Low Back Pain.

The purpose of this study was to report sleep quality from 4 weeks of auricular point acupressure that was designed for chronic low back pain and determine the relationship between pain intensity and sleep quality. Participants were randomized into the APA group (n = 30) or the sham-APA group (n = 31). At baseline assessment, 87% of the participants reported poor sleep quality. Participants who received APA had decreased daytime disturbance and improved global Pittsburgh Sleep Quality Index scores at end of intervention (EOI) and 1-month follow up compared to participants in the sham-APA group. For the APA group, both the sleep duration and wake after sleep onset decreased gradually during the 4-week APA (0.56% and 0.23% daily change, respectively).

Significant predictors of patients' uncertainty in primary brain tumors.

Patients with primary brain tumors (PBT) face uncertainty related to prognosis, symptoms and treatment response and toxicity. Uncertainty is correlated to negative mood states and symptom severity and interference. This study identified predictors of uncertainty during different treatment stages (newly-diagnosed, on treatment, followed-up without active treatment). One hundred eighty six patients with PBT were accrued at various points in the illness trajectory. Data collection tools included: a clinical checklist/a demographic data sheet/the Mishel Uncertainty in Illness Scale-Brain Tumor Form. The structured additive regression model was used to identify significant demographic and clinical predictors of illness-related uncertainty. Participants were primarily white (80 %) males (53 %). They ranged in age from 19-80 (mean = 44.2 ± 12.6). Thirty-two of the 186 patients were newly-diagnosed, 64 were on treatment at the time of clinical visit with MRI evaluation, 21 were without MRI, and 69 were not on active treatment. Three subscales (ambiguity/inconsistency; unpredictability-disease prognoses; unpredictability-symptoms and other triggers) were different amongst the treatment groups (P < .01). However, patients' uncertainty during active treatment was as high as in newly-diagnosed period. Other than treatment stages, change of employment status due to the illness was the most significant predictor of illness-related uncertainty. The illness trajectory of PBT remains ambiguous, complex, and unpredictable, leading to a high incidence of uncertainty. There was variation in the subscales of uncertainty depending on treatment status. Although patients who are newly diagnosed reported the highest scores on most of the subscales, patients on treatment felt more uncertain about unpredictability of symptoms than other groups. Due to the complexity and impact of the disease, associated symptoms, and interference with functional status, comprehensive assessment of patients is necessary throughout the illness trajectory.

Day-to-Day Changes of Auricular Point Acupressure to Manage Chronic Low Back Pain: A 29-day Randomized Controlled Study.

OBJECTIVE: The purpose of this study was to determine the effects of a 4-week auricular point acupressure (APA) treatment on chronic low back pain (CLBP) outcomes and examine the day-to-day variability of CLBP in individuals receiving APA for CLBP over 29 days. DESIGN: This was a prospective, randomized controlled trial (RCT). Data were collected at baseline, during each of the four office visits for APA treatment, after the completion of the 4-week intervention, and 1 month after the last treatment. A daily diary was given to each participant to record his or her APA practices, analgesic use, and pain intensity. INTERVENTIONS: APA was used to manage CLBP. The participants received one APA treatment per week for 4 weeks. PATIENTS AND SETTING: Sixty-one participants with CLBP were randomized into either a real APA or sham APA treatment group. Participants were recruited from primary care offices and clinics or through the Research Participant Registry at the University of Pittsburgh. RESULTS: Among participants in the real APA group, a 30% reduction of worst pain was exhibited after the first day of APA treatment, and continuous reduction in pain (44%) was reported by the completion of the 4-week APA. This magnitude of pain reduction reached the clinically significant level of improvement reported in other clinical trials of chronic pain therapies. Analgesic use by participants in the real APA group also was reduced compared with use by participants in the sham group. CONCLUSION: This study shows that APA is a promising pain management strategy that is not invasive and can be self-managed by participants for CLBP. Given the day-to-day fluctuation in ratings, the tighter ecologic assessment of pain scores and other treatment parameters are an important pragmatic aspect of the design of chronic pain studies.

Auricular point acupressure as an adjunct analgesic treatment for cancer patients: a feasibility study.

This study aimed (1) to examine the feasibility of an auricular point acupressure (APA) research protocol in terms of recruitment and for the assessment and management of pain and (2) to examine the potential APA analgesic effects for cancer patients. This study was a repeated-measures one-group design. Participants were recruited from the cancer center follow-up clinic affiliated with a large university hospital in the northeastern United States. Participants included 50 patients aged 55-87 years with a diagnosis of cancer. Participants received 7 days of APA treatment for their pain. After appropriate acupoints were identified, vaccaria seeds were carefully taped onto each selected auricular point on each ear. The study recruitment and retention rates were 92% and 91%, respectively. Importantly, the study found preliminary evidence for the analgesic effects of APA for cancer pain management. For example, by the end of the 7-day study, APA reduced pain intensity more than 55% for "worst pain" and about 57% for "average pain" and "pain intensity." Moreover, the use of pain medication was reduced during the APA treatment (e.g., 78% of patients [n = 39] took less pain medication than before the treatment). APA appears to be highly acceptable to patients with cancer-related pain. However, without a placebo control, we cannot draw conclusive evidence for the analgesic effect of APA for cancer patients. A sham group must be added to future studies to differentiate the true effects of APA from the possible psychological effects of the APA treatment.

Auricular point acupressure for chronic pain: a feasibility study of a 4-week treatment protocol.

This 1-group, 4-week observational study aimed to (1) assess the feasibility of recruiting, retention, and completion of a 4-week auricular point acupressure (APA) treatment protocol for chronic pain in adult patients and (2) assess the effects of APA in pain reduction (pain severity and pain interference) among these patients. The participants received a 4-week APA treatment protocol in weekly cycles. Each weekly cycle included 5 days with APA seeds taped onto the ear and 2 days without. Each participant was called every day to monitor adherence to the treatment protocol (the actual times the participant pressed the seeds each day and the duration of applied pressure), to answer analgesic use, and to answer the pain intensity questionnaire. Thirty participants were initially enrolled in this study, but 5 did not continue. The retention rate was 83% (n = 25). Approximately 60% of the participants (n = 15) adhered to the 4-week APA and completed all data assessments. At baseline assessment, only 40% of all participants (n = 12 of 30) were confident that APA would reduce and eliminate pain; nonetheless, all participants reported fewer episodes of pain occurrences and pain intensity with the APA treatment. For the participants who completed the 4-week APA protocol (n = 15), 96% (n = 14) decreased analgesic medication intake and 88% (n = 13) felt "much better" after the APA treatment. Participants reported an average reduction of 63% in the worst pain intensity at day 7. By the end of the 4-week APA protocol, an even greater reduction in pain intensity was reported (66%, n = 10, at day 28). The participants who did not complete the treatment protocol reported an average pain reduction of 29%, which fluctuated to 22% before they dropped out. Auricular point acupressure is feasible for patients with chronic pain. The preliminary findings of this feasibility study show a reduction in pain intensity and improvement in physical function, which demonstrate the potential for APA as a treatment option for patients with chronic pain.

The Influence of Hospital Physician Integration on Culture of Patient Safety.

BACKGROUND: Medical errors are responsible for a large number of deaths every year in the Unites States. Hospitals use various strategies including leadership, staffing, and structural changes to deal with this concerning issue. Hospital physician integration is a structural strategy to possibly improve patient safety. Using the conceptual lens of Donabedian's Structure Process Outcome model, this study aims to investigate how hospital physician integration affects organizational, management, and communication attributes of patient safety culture. METHODS: A pooled cross sectional study design using the Hospital Survey on Patient Safety Culture, the American Hospital Association data, and Area Health Resource File was used to analyze the relationship between hospital physician integration and organizational and management patient safety culture attributes. The dataset comprised of hospital level data from 2021 and 2022 for patient safety culture and hospital characteristics and contained a final sample of 205 observations. The independent variable was levels of integration across five levels. Three attributes of safety culture were chosen-positive perceptions of communication openness, organizational learning, and hospital management support for patient safety. The control variables were organizational characteristics. Multivariable linear regression was used as the analytic method. RESULTS: Findings demonstrated a statistically significant correlation between higher level of hospital physician integration and positive perceptions of hospital management support for patient safety. There are 0.063 higher positive perceptions of hospital management support for patient safety for higher levels of integration compared with lower levels of integration (P < 0.05). Perceptions of communication openness and organizational learning did not demonstrate a statistically significant correlation with any level of hospital physician integration. CONCLUSIONS: Hospital physician integration and hospital management support for patient safety were moderately but significantly related. Hospital physician integration allows resources to become available for physician. As physicians take on management roles management of resources and eventually performance can improve, there is a need for future research in this area to examine if integration is a step in the right direction to overcome the challenges of patient safety and if investments in resources and training can be beneficial to safety culture.
