Identification of rheumatoid arthritis in German claims data using different algorithms: Validation by cross-sectional patient-reported survey data.

To evaluate different algorithms for the identification of rheumatoid arthritis (RA) in claims data using patient-reported diagnosis as reference. Within longitudinal data from a large German statutory health insurance, we selected a random sample of persons with ICD-10 code for RA (M05/M06) in ≥2 quarters in 2013. The sample was stratified for age, sex, and M05/M06. Persons were asked to confirm RA diagnosis (gold standard), which was linked to claims data given consent. Analyses were weighted to represent the total RA population of the database. Positive predictive values (PPVs) and discriminative properties were calculated for different algorithms: ICD-10 code only, additional examination of inflammatory markers, prescription of specific medication, rheumatologist appointment, or combination of these. Of 6193 persons with a claims diagnosis of RA, 3184 responded (51%). Overall, PPV for the ICD-10 code was 81% (95% confidence interval 79%-83%) with 94% (92%-95%) for M05 and 76% (73%-79%) for M06. PPVs increased (with loss of case numbers) if inflammatory markers (82% [80%-84%]), rheumatology visits (85% [82%-87%]) or specific medication (89% [87%-91%]) had been used in addition. Specific medication had the best discriminative properties (diagnostic odds ratio of 3.0) among persons with RA diagnosis. The ICD-10 codes M05 and (less optimal) M06 have high PPVs and are valuable to identify RA in German claims data. Depending on the respective research question, researchers should use different criteria for identification of RA.

South African Study into Healing Planetary Pollution

"The accelerating destructive effects of pollution threaten the existence of all inhabitants of planet earth. Health promotion interventions inevitably include a dynamic harmony of various interacting planetary components and contexts, bio-psycho-social as well as spiritual, cultural and ecological. This study was based on a broad research question as to what would best heal polluted planet earth. As with most countries, South Africa is slowly recovering from the effects of COVID-19. It seemed timeous to investigate a local sample of knowledgeable and experienced persons with regard to their views on pollution prevention and health promotion. Sixteen local KwaZulu-Natal persons responded to an online google questionnaire. There were 5 men and 11 women, with a mean age of 55 and age range from 25 to 73 years. Data analysis using NVivo12 software indicated that participants’ responses generally coalesced into a coherent health promotion theme including subthemes of awareness, education, regulation, and action to prevent human destructiveness, promote healing and the holistic integrity of nature. Unique local findings as well as those similar to other studies are discussed. Further research could include formal scales with larger local and international samples in interconnected, ecological and health promotion initiatives."

Integration of rotating disk sorptive extraction and dispersive-solid phase extraction for the determination of estrogens and their metabolites in urine by liquid chromatography/mass spectrometry

The matrix of certain complex samples represents a great challenge in microextraction technology due to its ability to interfere with some step of the sample preparation procedure or in the detection itself. Normally, a suppression of the analytical signal occurs by the presence of certain components of the matrix, which tend to be coextracted with the analytes under study. Urine represents one of these complex matrices. The yellow coloration of urine comes from a main pigment known as urobilin, which can persist in all final extracts after sample treatment and has been correlated with the impossibility of correctly measuring the analytes. In the present study, we propose the determination of estrogens and their hydroxylated metabolites in urine by integration of a dispersive solid phase extraction (d-SPE) to eliminate the matrix effect with the rotating disk sorptive extraction (RDSE) of the analytes, prior to their determination by liquid chromatography/mass spectrometry.The proposed dispersive phase was primary-secondary amine (PSA), which, due to its physicochemical characteristics, allows the extraction of polar compounds (such as urobilin). Estrogens and their hydroxylated metabolites, being molecules of lower polarity, were demonstrated not to be removed by PSA and were extracted only by the styrene–divinylbenzene phase supported in the rotating disk. The amount of dispersive phase was optimized, finding that 300 mg is the best analytical response for 2 mL of urine sample. The equilibrium time for the extraction of the analytes was 60 min.Matrix-matched calibration was used for quantification, obtaining correlation coefficients greater than 0.99, limits of detection and quantification between 0.10 and 0.13 and 0.3–0.5 µg/L, respectively, and recoveries between 72 and 130 % with precision, expressed as relative standard deviation, between 8 and 17 %. The matrix effect was reduced significantly between −24 and −48 % (without the use of d-SPE, most of the analytes were not detected). In addition, the proposed method was applied to the determination of the analytes in real urine samples of different persons. Finally, through enzymatic hydrolysis, it was possible to quantify estrogens and their hydroxylated metabolites in urine samples, both in their total form and in their naturally conjugated form.

Prevalence of Diabetes Among Community-Living Older Persons in the Philippines: The FITforFrail Study.

To estimate the prevalence of diabetes among Filipino older persons living in the community. A cross-sectional analysis was done on a random sample of persons 60 years and older from the Focused Interventions for Frail Older Adults Research and Development Program (2018-2019). A diagnosis of diabetes was established by self-reported physician's diagnosis or if the person was on any antihyperglycemic drugs. The prevalence of self-reported diabetes was 20.5%, with no difference in age, sex, education, or body mass index between older persons with and without diabetes. The presence of 2 or more comorbidities was significantly more common among older persons with diabetes (p<0.001). Visual impairment (p<0.01), hypertension (p<0.001) and hyperlipidemia (p<0.001) were more frequent among those with diabetes. Diabetes is prevalent among community-living older Filipinos. Therefore, effective public health measures for diabetes prevention and management are needed for the ever-growing older population, who are at the highest risk for morbidity and mortality.

The Impact of the COVID-19 Lockdown on the Cognitive Functions in Persons with Intellectual and Developmental Disabilities

The main objective of the research was to compare the cognitive functioning of a sample of persons with IDD (Intellectual and Developmental Disabilities) before the pandemic (2019) and after the pandemic (2020 and 2021), and to analyse the impact according to age and level of IDD impairment. The participants were 92 persons with IDD, of whom 43 were female (46.7%). The mean age in 2019 was 47.07 years (SD = 6.78). All the participants were living with family members. The CAMCOG-DS test from CAMDEX was used to assess the cognitive functions. The results indicate a worsening in cognitive functions (attention-concentration, abstract thought, language, and praxis) after lockdown, in both the total group of participants and the mild-moderate impairment group, and in both age groups. In the severely affected group, we found an improvement in the cognitive functions assessed after lockdown. These results are similar to those found in people with dementia and in the general ageing population. Results were discussed in relation to the consequences of isolation in people with IDD, as well as providing guidelines for future pandemic situations.

Loneliness, Depression, and Genetics in the Elderly: Prognostic Factors of a Worse Health Condition?

Loneliness is considered a prognostic factor for poorer health status in the elderly. It is proposed to analyze the role of loneliness in health status in terms of various factors. A total of 1747 individuals from the pilot survey of the Aging in Spain Longitudinal Study (ELES-PS) were reviewed. ELES is a cross-sectional study for collecting health variables, food habits, socioeconomic data, and cognitive and functional capacities, which was carried out on a Spanish representative sample of noninstitutionalized persons of 50 years of age or older. Moreover, since telomere shortening is associated with cellular senescence, 35 telomere-related SNPs and cognitive impairments were analyzed. The results characterize the "solos" as males of 50-60 years, who were overweight and had lower levels of hemoglobin and neutrophils. There is also an association between five SNPs related to telomere length and BDNF. A group of people with loneliness and depression was identified with poorer health and cognitive status, poorer perception of their quality of life, poorer quality of sleep, and lower physical activity. Therefore, it follows that telomeres and BDNF play a role as intermediaries between loneliness and depression and their relationship with a worse state of health.

Determinants of exposure to endocrine disruptors following hurricane Harvey

Hurricane Harvey was a category four storm that induced catastrophic flooding in the Houston metropolitan area. Following the hurricane there was increased concern regarding chemical exposures due to damage caused by flood waters and emergency excess emissions from industrial facilities. This study utilized personal passive samplers in the form of silicone wristbands in Houston, TX to both assess chemical exposure to endocrine disrupting chemicals (EDCs) immediately after the hurricane and determine participant characteristics associated with higher concentrations of exposure. Participants from the Houston-3H cohort (n = 172) wore a wristband for seven days and completed a questionnaire to determine various flood-related and demographic variables. Bivariate and multivariate analysis indicated that living in an area with a high Area Deprivation Index (ADI) (indicative of low socioeconomic status), identifying as Black/African American or Latino, and living in the Houston neighborhoods of Baytown and East Houston were associated with increased exposure to EDCs. These results provide evidence of racial/ethnic and socioeconomic injustices in exposure to EDCs in the Houston Metropolitan Area. Since the multiple regression models conducted did not fully explain exposure (0.047 < R2 < 0.34), more research is needed on the direct sources of EDCs within this area to create effective exposure mitigation strategies.

Decreasing patterns of depression in living alone across middle-aged and older men and women using a longitudinal mixed-effects model

There is little evidence regarding the association between living arrangement and depression, and no studies have examined the age- and gender-specific differences in this association. The present study sought to examine the longitudinal changes in depression patterns between isolative living versus living in company among middle-aged and older men and women by obtaining data from waves 1–7 of the Korean Longitudinal Study of Aging (KloSA), which comprises a sample of persons at least 45 years of age in the Republic of Korea (2273 middle-aged and 1387 older men, 2805 middle aged and 1862 older women). Depression scores were based on the self-reported Center for Epidemiologic Studies Depression Scale (CES-D-10) short forms. Using mixed-effect linear regression models, we estimated depression patterns by living arrangement across age- and gender groups. Our findings from the mixed-effects model revealed that over a 14-year follow-up period, there were significant decreasing patterns of depression were among middle-aged men and women, and older men living alone compared to living with a spouse and living with others. However, living alone still had the highest depression compared to other living arrangement types. On the other hand, the depression of older women living alone changed to a level similar to those living with others during the follow-up period. In conclusion, these findings indicate that living alone significantly increases the risk of depression, but the risk decreases over time. Additionally, depression patterns by living arrangement proved to differ across age and gender groups.

Development and performance evaluation of a two-stage cascade impactor equipped with gelatin filter substrates for the collection of multi-sized particulate matter

This study presents the development and evaluation of a high flow rate gelatin cascade impactor (GCI) to collect different PM particle sizes on water-soluble gelatin substrates. The GCI operates at a flow rate of 100 lpm, and consists of two impaction stages, followed by a filter holder to separate particles in the following diameter ranges: >2.5 μm, 0.2–2.5 μm, and <0.2 μm. Laboratory characterization of the GCI performance was conducted using monodisperse polystyrene latex (PSL) particles as well as polydisperse ammonium sulfate, sodium chloride, and ammonium nitrate aerosols to obtain the particle collection efficiency curves for both impaction stages. In addition to the laboratory characterization, we performed concurrent field experiments to collect PM2.5 employing both GCI equipped with gelatin filter and personal cascade impactor sampler (PCIS) equipped with PTFE filter for further toxicological analysis using macrophage-based reactive oxygen species (ROS) and dithiothreitol consumption (DTT) assays. Our results showed that the experimentally determined cut-point diameters for the first and second impaction stages were 2.4 μm and 0.21 μm, respectively, which agreed with the theoretical predictions. Although the GCI has been developed primarily to collect particles on gelatin filters, the use of a different type of substrate (i.e., quartz) led to similar particle separation characteristics. The findings of the field tests demonstrated the advantage of using the GCI in toxicological studies due to its ability to collect considerable PM-toxic constituents, as corroborated by the DTT and ROS values for the GCI-collected particles which were 26.44 nmol/min/mg PM and 8813.2 μg Zymosan Units/mg PM, respectively. These redox activity values were more than twice those of particles collected concurrently on PTFE filter using the PCIS. This high-flow-rate impactor can collect considerable amounts of size-fractionated PM on water-soluble filters (i.e., gelatin), which can completely dissolve in water allowing for the extraction of soluble and insoluble PM species for further toxicological analysis.

Applying the Stress Process Theory to Assess Correlates of Suicide Ideation-to-Action Among Persons on Parole in the United States.

There is limited knowledge regarding precipitating factors associated with suicidality among persons on parole. Pairing the suicide ideation-to-action framework and stress process theory, the present study aimed to characterize sources of major stress (drug use, physical health, and mental health) and their associations to suicide ideation, planning, and attempt among a national sample of persons on parole. This study included a subsample of persons on parole (N = 1725) using pooled national data from the National Survey on Drug Use and Health (2015-2019). A series of logistic regression results indicate that various drug use, physical health, and mental health factors significantly influenced all three suicidality measures. Due to this population's unique experiences and numerous barriers following release from prison, it is essential to personalize interventions geared toward this population to meet their specific needs and address suicidality based on where they fall on this continuum.

Associations between Duration of Homelessness and Cardiovascular Risk Factors: A Pilot Study.

Cardiovascular disease (CVD) in the United States disproportionally affects people who are homeless. This disparity is a critical concern that needs to be addressed to improve the health of individuals who are homeless. The connections between a history of homelessness, i.e., its duration and frequency, and CVD risk are not well understood. The present study sought to investigate how a history of homelessness is correlated with CVD risk factors in a sample of homeless persons in the Deep South. This study recruited participants who were homeless from two local adult homeless shelters in Birmingham, AL. Participants (n = 61) underwent interviews, physical measurements, and a capillary blood draw. Their mean age was 47 years, and 82% were men. Results showed the duration of homelessness was positively associated with several CVD risk factors (diabetes mellitus, total cholesterol, and low-density lipoprotein). However, there was no significant association between frequency of homelessness and any CVD risk factors. To get the more accurate estimate of CVD risk in this population, future research should incorporate additional risk factors related to homelessness and seek to develop a robust strategy to collect an accurate history of homelessness.

Human biomonitoring and personal air monitoring. An integrated approach to assess exposure of stainless-steel welders to metal-oxide nanoparticles

In welding, there is a potential risk due to metal-oxide nanoparticles (MONPs) exposure of workers. To investigate this possibility, the diameter and number particles concentration of MONPs were evaluated in different biological matrices and in personal air samples collected from 18 stainless-steel welders and 15 unexposed administrative employees engaged in two Italian mechanical engineering Companies. Exhaled breath condensate (EBC) and urine were sampled at pre-shift on 1st day and post-shift on 5th day of the workweek, while plasma and inhalable particulate matter (IPM) at post-shift on 5th day and analysed using the Single Particle Mass Spectrometry (SP-ICP-MS) technique to assess possible exposure to Cr2O3, Mn3O4 and NiO nanoparticles (NPs) in welders. The NPs in IPM at both Companies presented a multi-oxide composition consisting of Cr2O3 (median, 871,574 particles/m3; 70 nm), Mn3O4 (median, 713,481 particles/m3; 92 nm) and NiO (median, 369,324 particles/m3; 55 nm). The EBC of welders at both Companies showed Cr2O3 NPs median concentration significantly higher at post-shift (64,645 particles/mL; 55 nm) than at pre-shift (15,836 particles/mL; 58 nm). Significantly lower Cr2O3 NPs median concentration and size (7762 particles/mL; 44 nm) were observed in plasma compared to EBC of welders. At one Company, NiO NPs median concentration in EBC (22,000 particles/mL; 65 nm) and plasma (8248 particles/mL; 37 nm) were detected only at post-shift. No particles of Cr2O3, Mn3O4 and NiO were detected in urine of welders at both Companies. The combined analyses of biological matrices and air samples were a valid approach to investigate both internal and external exposure of welding workers to MONPs. Overall, results may inform suitable risk assessment and management procedures in welding operations.

Assessment of Kratom Use Disorder and Withdrawal Among an Online Convenience Sample of US Adults.

Since 2007, kratom use in the United States has increased, centered around nonmedical self-treatment of pain, psychiatric, and substance use disorder symptoms. Reports of kratom withdrawal have emerged amidst description of therapeutic effects, yet we know little about disordered use. Our objective was to assess Diagnostic and Statistical Manual-5 substance use disorder for kratom ("kratom use disorder," KUD) and examine kratom withdrawal symptoms among those who ever used regularly. We also sought to identify clinical characteristics of respondents who qualified for current, remitted, or never KUD. Between April and May 2021, we re-recruited online respondents who reported lifetime kratom use on an unrelated survey into our cross-sectional kratom survey study, permitting a diverse sample of current and former kratom-using persons. A total of 129/289 (44.6%) evaluable surveys were obtained. Over half (52.7%) of respondents never met KUD diagnostic criteria; 17.8% were assessed remitted, and 29.5% met current (past-year) KUD threshold. For past-year KUD, severity was: 14.0% mild, 7.0% moderate, and 8.5% severe. Pain, psychiatric symptoms, and polydrug use were found across all groups. KUD symptoms reflected increased use, tolerance, withdrawal, unsuccessful quit attempts, and craving; 9.3% reported decreases in important social, occupational, or recreational activities because of use. Withdrawal symptoms were moderate and included gastrointestinal upset, restlessness, anxiety, irritability, fatigue/low energy, and craving. As assessed here, tolerance and withdrawal are primary KUD features rather than psychosocial impairments. As kratomis often used among persons with a myriad of health conditions, clinicians should be aware of and assess for kratom use and withdrawal.

Introducing the APOD: Analysis of patterns of denial among males accused of sexual offending

Sex offenders have great incentive to deny and/or minimize their offense, and both researchers and treatment providers regularly encounter their socially desirable response patterns. Despite the importance of distinguishing those who are lying about their innocence from those who are truly not culpable, law enforcement agencies and clinicians have few resources, other than the polygraph, to discern false denial from truthful, actual denial using scientifically supported methods. The Analysis of Patterns of Denial (APOD), a checklist of denial techniques, was developed to assist in making this distinction. It was developed by comparing a sample of guilty persons who denied their offense conduct with persons who were falsely accused (i.e., accused and investigated but later convincingly cleared by polygraph, a DNA non-match, and/or confession by another person). Items that satisfactorily discriminated between the two groups were retained in the final checklist. The APOD is intended to help those who work with sex offenders identify denial response patterns to more accurately determine if an alleged sex offender is being truthful or deceptive.

Silicone wristbands as personal passive sampling devices: Current knowledge, recommendations for use, and future directions.

Personal chemical exposure assessment is necessary to determine the frequency and magnitude of individual chemical exposures, especially since chemicals present in everyday environments may lead to adverse health outcomes. In the last decade, silicone wristbands have emerged as a new chemical exposure assessment tool and have since been utilized for assessing personal exposure to a wide range of chemicals in a variety of populations. Silicone wristbands can be powerful tools for quantifying personal exposure to chemical mixtures in a single sample, associating exposure with health outcomes, and potentially overcoming some of the challenges associated with quantifying the chemical exposome. However, as their popularity grows, it is crucial that they are used in the appropriate context and within the limits of the technology. This review serves as a guide for researchers interested in utilizing silicone wristbands as a personal exposure assessment tool. Along with briefly discussing the passive sampling theory behind silicone wristbands, this review performs an in-depth comparison of wristbands to other common exposure assessment tools, including biomarkers of exposure measured in biospecimens, and evaluates their utility in exposure assessments and epidemiological studies. Finally, this review includes recommendations for utilizing silicone wristbands to evaluate personal chemical exposure and provides suggestions on what research is needed to recognize silicone wristbands as a premier chemical exposure assessment tool.

Flow Injection Sensing Strategy for Determining Cationic Surfactants in Commodity and Water Samples

The formation of stable binary water-soluble sub-micellar aggregates of cetyltrimethylammonium bromide-copper-pyrocatechol violet complex (CTAB-Cu-PCV) diminishes the stability and absorbance of the Cu-PCV complex. A new flow injection spectrophotometric sensing strategy used for the determination of CTAB in commodity personal care antiseptics and water samples has been established relying on the above-mentioned concept. Based on the reduction of the absorption of the Cu-PCV solution by the injection of CTAB solution at pH 6.0 and 430 nm, a linear absorbance decrease was observed over the CTAB concentration range of 2.0 to 100.0 µg mL−1 (r = 0.987). The analysis method showed limits of detection (3.3 ơ) and quantification (10 ơ) of 0.08 and 0.27 µg mL−1, respectively. The precision (RSD) for five replicate determinations was 7.9 and 3.7% at 10 and 50 µg mL−1, respectively. The developed method was applied successfully to the determination of CTAB in personal care products, namely skin lotion and vaginal wash, in addition to water samples. The corresponding RSD (n = 5) values were ≤8.2%.

Durable viral suppression among persons with HIV in the deep south: an observational study

ABSTRACT This study assessed predictors of stable HIV viral suppression in a racially diverse sample of persons living with HIV (PWH) in the southern US. A total of 700 PWH were recruited from one of four HIV clinics in Metro Atlanta, GA. Data were collected from September 2012 to July 2017, and HIV viral loads were retrieved from EMR for 18 months. The baseline visits and EMR data were used for current analyses. Durable viral suppression was categorized as 1. Remain suppressed, 2. Remain unsuppressed, and 3. Unstable suppression. The number of antiretroviral medications and age were significantly associated with durable viral suppression. Older age, fewer ART medications and availability of social support were positively associated with durable viral suppression over the 18-month observation period. Findings suggest that regimen complexity is potentially a better predictor of viral suppression than self-reported medication adherence. The need for consensus on the definition of durable viral suppression is also urged.

“It’s been a double-edged sword”: An online qualitative exploration of the impact of COVID-19 on individuals with spinal cord injury in the US with comparisons to previous UK findings

Objective The impact of COVID-19 lockdowns and social distancing for persons with spinal cord injury (SCI) are poorly understood. This exploratory online qualitative study collected self-reported COVID-19 experiences from persons with SCI in the United States (US). To enrich understanding, these data were compared to similar previously-published data from a sample of SCI participants from the United Kingdom (UK). Design Explorative, online qualitative study. Participants completed an online survey of open-ended qualitative questions pertaining to their experiences during the pandemic. Thematic analysis was utilized to generate themes from the US data. These themes were compared to our previously-published thematic analysis of data from the UK. Setting Community-based sample of persons with SCI in the US. Participants Participants were recruited via SCI-focused research registries and social media outlets serving the SCI community, using convenience sampling (n = 36). Key themes identified in the US data were compared to themes identified in a similar sample from the UK (n = 42) collected at the same time and published previously. Results Analysis resulted in three themes from the US data, each containing positive and negative qualitative reflections. Themes included (1) health and access to care, (2) making sense of the pandemic, and (3) daily life during the pandemic. Each theme captured common facets of life during the pandemic, often shared by those without physical disabilities, but included accounts particularly relevant to persons with disabilities. Comparisons to thematic findings from the UK study revealed similarities (e.g. healthcare access challenges, isolation) and differences (e.g. importance of previous SCI experiences). Conclusion We detailed common experiences of COVID-19 pandemic lockdowns and their impact on people with SCI, while contrasting these with sense-making positive reflections and social benefits that appeared to be helpful in managing distress and coping with the pandemic.

Evaluation of asbestos exposure resulting from simulated application of spiked talcum powders

This study characterizes airborne asbestos exposures resulting from the adult application of cosmetic talc body powders spiked with known concentrations of tremolite. Raw talc ores were spiked with 0.005% and 0.1% asbestiform or non-asbestiform tremolite. Personal samples were collected during 16 simulated events, including puff and shaker application and associated clean-up activities. Airborne fiber levels (PCM) were not significantly different for simulations involving talc spiked with asbestiform and non-asbestiform tremolite (p = 0.6104). For application and clean-up of talc spiked with 0.005% asbestiform tremolite, 2 of 24 (8.3%) samples were above the LOD for TEM (0.003 f/cc). For application of talc spiked with 0.1% asbestiform tremolite, 21 of 24 (87.5%) were above the LOD for TEM. The corresponding mean PCME asbestos concentrations were 0.016 f/cc for puff and shaker for samples collected in the first 15 min, 0.002 f/cc for puff and 0.004 f/cc for shaker in the second 15 min, and 0.005 f/cc for puff and 0.013 f/cc for shaker for the full 30 min. Mean PCME concentrations for samples collected during clean-up following application of talc spiked with 0.1% asbestiform tremolite were 0.003 f/cc for samples collected in the first 15 min following puff application, 0.005 f/cc for samples collected in the second 15 min following shaker application, and 0 f/cc for the remaining clean-up samples. Using the EPA’s exposure factors, we determined the range of cumulative asbestiform fiber exposures that would result from product use, assuming asbestiform tremolite was present at 0.1%.
