Quantifying the impact of COVID-19 restrictions on air pollution in Ahvaz: a comparative dual-approach assessment of observed against baseline and forecasted criteria air pollutants

Environ Monit Assess. 2024 Oct 19;196(11):1079. doi: 10.1007/s10661-024-13231-8.

ABSTRACT

In response to the COVID-19 pandemic, the Iranian government swiftly implemented immediate and decisive measures to control the spread of the infection. This study aims to demonstrate the impact of restriction measure on air pollution, also to highlight the potential variability in results that can arias from different methodological approach. A comprehensive dual-approach assessment was conducted to evaluate the effect of the lockdown measures on criteria air pollutants. Firstly, a traditional approach compared air quality during the pandemic period with baseline conditions from 2013 to 2019. Secondly, observed air pollution values during different periods with varying restrictions in 2020 were compared with expected values. This comprehensive analysis allows for a robust comparison and quantification of the impact of different lockdown measures in Ahvaz. The study revealed significant changes in air pollutant concentrations in Ahvaz during 2020, with variations observed across different pollutants. Notable reductions were observed in O3 levels, particularly in November (-54.44% compared to the baseline) and December (-63.58% compared to expected values). Decreases in CO levels were observed in multiple months, while substantial reductions in PM10 and PM2.5 were observed during various periods. Inconsistencies in the magnitudes and directions of changes were found when comparing baseline and forecasted values. The overall stringency index showed an inverse association with changes in O3, NO2, and CO, with international travel controls and restrictions on internal movement having significant impacts. This study provides valuable insights into the impact of COVID-19 lockdown measures on air pollution in Ahvaz, Iran, using a comprehensive dual-approach assessment. The findings highlight the effectiveness of these measures in reducing specific criteria air pollutants and emphasize the importance of implementing appropriate strategies for air quality management during similar public health emergencies.

Do job demands and resources differ between permanent and temporary eldercare workers in Sweden?

Ann Work Expo Health. 2024 Oct 19:wxae077. doi: 10.1093/annweh/wxae077. Online ahead of print.

ABSTRACT

INTRODUCTION: Eldercare organizations face high sickness absence rates and staff turnover and rely heavily on temporary workers to fill staffing gaps. Temporary workers may experience differences in job demands and resources compared with permanent workers, but this has been largely understudied.

OBJECTIVE: To compare perceived job demands and resources between permanent and temporary Swedish eldercare workers.

METHODS: Permanent and temporary eldercare workers in a Swedish municipality were invited to answer a digital survey on work environment conditions. Differences between permanent and temporary workers in job demands and resources were analyzed using multivariate analysis of variance adjusted for age, sex, place of birth, and percent of full-time work and univariate analyses were conducted to consider differences in specific factors.

RESULTS: A total of 1076 permanent and 675 temporary workers received the survey, and the final study sample included 451 permanent and 151 temporary workers. Multivariate analyses revealed that temporary workers reported statistically significant lower job demands compared to permanent workers, but no statistically significant differences in resources were found between the groups. Univariate analyses showed that temporary workers reported lower quantitative demands, perceived exertion, and time spent bending forward, than permanent workers. These data suggest comparable support across groups, but a higher workload among permanent workers.

CONCLUSION: Our findings indicate that temporary workers experienced lower job demands than permanent workers, but that no notable difference was found in resources. Interventions aimed at distributing job demands more evenly among eldercare workers with different employment forms may be necessary.

Prescription Opioid Use before and after Diagnosis of Cancer Among Older Cancer Survivors With Non-Cancer Chronic Pain Conditions (NCPCs): An Application of Group-Based Trajectory Modeling (GBTM)

Cancer Control. 2024 Jan-Dec;31:10732748241290769. doi: 10.1177/10732748241290769.

ABSTRACT

BACKGROUND: Prescription opioids are essential in managing pain among adults with chronic pain conditions. However, persistent use over time can lead to negative health consequences. Identifying individuals with persistent use over time and their characteristics can inform clinical decision-making and aid in reducing the risk of abuse and overdose deaths.

OBJECTIVE: This study aims to examine trajectories of prescription opioid use over time and factors associated with these trajectories among older cancer survivors with any non-cancer pain conditions (NCPC).

METHODS: We conducted a retrospective cohort study design with longitudinal data of older (age at cancer diagnosis ≥67 years) cancer (incident breast, colorectal, and prostate cancers, or non-Hodgkin lymphoma) survivors with any NCPC. Data were derived from the 2007-2015 linked Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset (N = 35,071). Group-Based Trajectory Modeling (GBTM) was used to identify homogeneous subgroups (distinct trajectories) of individuals based on every 90-day prescription opioid use during pre-cancer diagnosis (t1-t4), acute cancer treatment (t5-t8), and post-cancer treatment (t9-t12) periods. Biological factors, social determinants of health (SDoH), physical and mental health, medication use, health care use, and external factors associated with a trajectory membership were analyzed with multivariable multinomial logistic regressions.

RESULTS: Four distinct trajectories of opioid use were identified: (1) increase-decrease use (6.1%); (2) short-term use after cancer diagnosis (40.6%); (3) low-use (41.0%); and (4) persistent use (12.3%). In the fully-adjusted multinomial logistic regression, the SDoH such as Non-Hispanic Black [adjusted odds ratios (AOR) = 1.69; 95%CI = 1.48, 1.93)] and rural residence (AOR = 1.49; 95%CI = 1.15, 1.94)], comorbid anxiety (AOR = 1.33; 95%CI = 1.18, 1.51), and medication use (NSAIDs – AOR = 1.20; 95%CI = 1.10, 1.30) were associated with membership in the persistent use group. Persistent use was less likely among those with higher fragmented care index (AOR = 0.95, 95%CI = 0.93, 0.97) and those living in counties with higher Medicare advantage penetration (AOR = 0.96; 95%CI = 0.95, 0.97).

CONCLUSIONS: One in eight older adults had persistent opioid use over time. The profile characteristics of this group were different from the other trajectory groups. Policies and programs to reduce chronic opioid use need to consider the intra- and inter-individual variability to reduce opioid-related morbidity and mortality.

Safety and efficacy of adipose-derived mesenchymal stem cell therapy in elderly Parkinson’s disease patients: an intermediate-size expanded access program

Cytotherapy. 2024 Oct 5:S1465-3249(24)00885-5. doi: 10.1016/j.jcyt.2024.09.004. Online ahead of print.

ABSTRACT

OBJECTIVE: This intermediate-size expanded access program aimed to evaluate safety and clinical efficacy of multiple intravenous infusions of autologous, Hope Biosciences adipose-derived mesenchymal stem cell (HB-adMSC) therapy in elderly patients with Parkinson’s disease (PD).

METHODS: Ten eligible participants (aged 76-95 years) received six intravenous infusions each with 200MM autologous HB-adMSCs over 18 weeks, with the end of study (EOS) at week 26. Safety was assessed through adverse events (AEs) and serious adverse events (SAEs). Efficacy was measured through improvements in both motor and non-motor symptoms, utilizing scales including Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) parts I-IV, Parkinson’s Disease Questionnaire-39 (PDQ-39), Parkinson’s disease Fatigue Scale (PFS-16), Patient Health Questionnaire-9 (PHQ-9), and Visual Analog Scale (VAS). Analysis employed paired t-tests and Minimal Clinically Important Difference (MCID) thresholds for the patient-reported outcomes.

RESULTS: Most AEs (37 out of 46) were mild in severity, with 5 SAEs reported, none attributed to the drug. No deaths occurred. Despite lack of statistical significance across the efficacy endpoints, modest yet clinically meaningful improvements with effect size > 0.3 were observed in several secondary efficacy endpoints (MDS-UPDRS part I & III, PDQ-39, and PHQ-9) at the EOS, nearing or surpassing the established MCID values.

CONCLUSIONS: The administration of autologous 200MM HB-adMSCs was found to be safe and well-tolerated in the elderly PD population. Although not achieving statistical significance, modest clinical improvements were noted across multiple secondary endpoints. These findings underscore the safety profile of the treatment in elderly patients and highlight the importance of evaluating clinical relevance alongside statistical measures for meaningful patient outcomes. Further investigation with a larger, randomized, placebo-controlled design is warranted to validate these observations.

Personalized Theta Transcranial Alternating Current Stimulation and Gamma Transcranial Alternating Current Stimulation Bring Differential Neuromodulatory Effects on the Resting Electroencephalogram: Characterizing the Temporal, Spatial, and Spectral Dimensions of Transcranial Alternating Current Stimulation

Neuromodulation. 2024 Oct 18:S1094-7159(24)00673-1. doi: 10.1016/j.neurom.2024.08.008. Online ahead of print.

ABSTRACT

OBJECTIVES: The neuromodulatory effects of transcranial alternating current stimulation (tACS) on electroencephalogram (EEG) dynamics are quite heterogenous. The primary objective of the study is to comprehensively characterize the effects of two tACS protocols on resting-state EEG.

MATERIALS AND METHODS: A total of 36 healthy participants were recruited and were randomized into three groups. Two groups received either personalized theta (4-8 Hz) or gamma (40 Hz) stimulation bilaterally in the frontal regions for 20 minutes (4 minutes ON, 1 minute OFF, four cycles). The third group performed relaxed breath watching for 20 minutes. Artifact-free, 1-minute EEG segments from the baseline, during tACS, and after stimulation resting EEG were characterized to see the effects of tACS. Threshold-free cluster enhanced permutation tests (for spectral measures) and two-way mixed analysis of variance (for aperiodic slope) were used for statistical inferences.

RESULTS: Current modeling simulation using ROAST with preset parameters (800 μA, AF3 AF4 locations) showed that induced electric fields can activate frontal cortical regions. During the stimulation period, personalized theta tACS entrained theta band power in the centro-parietal areas. There was a compensatory power decrease in the beta and gamma bands after theta tACS. No entrainment effects were observed for gamma tACS during stimulation, but a significant entrainment was observed in the theta and beta bands in the parieto-occipital regions after stimulation. The delta band power decreased in the central regions. No spectral modulations were seen after breath watching. The spectral slope, which measures aperiodic activity, was not affected by either breath watching or tACS.

CONCLUSIONS: Characterizing the effects of multiple tACS protocols is critical to effectively target specific neural oscillatory patterns and to personalize the protocols. The study can be extended to target specific oscillatory patterns associated with cognitive deficits in neuro-psychiatric conditions.

Observational Health Data Science and Informatics and Hand Surgery Research: Past, Present, and Future

J Hand Surg Am. 2024 Oct 17:S0363-5023(24)00433-7. doi: 10.1016/j.jhsa.2024.09.009. Online ahead of print.

ABSTRACT

Single center studies are limited by bias, lack of generalizability and variability, and inability to study rare conditions. Multicenter observational research could address many of those concerns, especially in hand surgery where multicenter research is currently quite limited; however, there are numerous barriers including regulatory issues, lack of common terminology, and variable data set structures. The Observational Health Data Sciences and Informatics (OHDSI) program aims to surmount these limitations by enabling large-scale, collaborative research across multiple institutions. The OHDSI uses the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) to standardize health care data into a common language, enabling consistent and reliable analysis. The OMOP CDM has been transformative in converting multiple databases into a standardized code with a single vocabulary, allowing for coherent analysis across multiple data sets. Building upon the OMOP CDM, OHDSI provides an extensive suite of open-source tools for all research stages, from data extraction to statistical modeling. By keeping sensitive data local and only sharing summary statistics, OHDSI ensures compliance with privacy regulations while allowing for large-scale analyses. For hand surgery, OHDSI can enhance research depth, understanding of outcomes, risk factors, complications, and device performance, ultimately leading to better patient care.

Effect of Foot Position on Ankle Muscle Activity During Wobble Board Training in Individuals With Chronic Ankle Instability

J Manipulative Physiol Ther. 2024 Oct 19:S0161-4754(24)00065-4. doi: 10.1016/j.jmpt.2024.09.007. Online ahead of print.

ABSTRACT

OBJECTIVE: The purpose of this study was to compare the effects of foot positioning on muscle activities of the peroneus longus (PL), medial gastrocnemius (MG), and tibialis anterior (TA)/PL ratio in individuals with chronic ankle instabilities (CAI) during wobble board training.

METHODS: Thirty individuals with CAI were included, and statistical significance of PL and MG muscle activities was determined using 1-way repeated measures analysis of variance alongside TA/PL activity ratio at the university research laboratory. The participants performed the wobble board training in 3 different foot positions: medial from the centerline of the wobble board (WBT-M), middle from the centerline of the wobble board, and lateral from the centerline of the wobble board (WBT-L). Peroneus longus, MG, and TA muscle activities were measured using surface electromyography.

RESULTS: Peroneus longus activity was significantly higher in the WBT-L position than in the other 2 positions, and it was significantly higher in the middle from the centerline of the wobble board than in the WBT-M position. Medial gastrocnemius activity was significantly greater in the WBT-L position than in the other 2 positions. Tibialis anterior/PL ratio was higher in the WBT-M position than in the other 2 positions.

CONCLUSION: The findings of this study showed that WBT-L increased PL muscle activity by >70% of the maximal voluntary isometric contraction without increasing TA/PL ratio in individuals with CAI.

Exploring the Interplay Between Kinesiophobia, Lumbar Joint Position Sense, Postural Stability, and Pain in Individuals With Chronic Low Back Pain: A Cross-Sectional Analysis

J Manipulative Physiol Ther. 2024 Oct 16:S0161-4754(24)00061-7. doi: 10.1016/j.jmpt.2024.09.004. Online ahead of print.

ABSTRACT

OBJECTIVE: The objectives of the study were to (1) determine the association between kinesiophobia and lumbar joint position sense (JPS) in individuals with chronic low back pain (CLBP); (2) examine the relationship between kinesiophobia and postural stability in individuals with CLBP; and (3) investigate whether pain intensity mediates the relationship between kinesiophobia, lumbar JPS, and postural stability in individuals with CLBP.

METHODS: In this cross-sectional study, a total of 83 individuals diagnosed with CLBP were included. The level of fear of movement was assessed using the Tampa Scale for Kinesiophobia (TSK). Lumbar JPS was measured using the active target repositioning technique, which involved evaluating JPS in 3 directions: lumbar flexion, side-bending to the left, and side-bending to the right. The repositioning accuracy of the lumbar joint was quantified in degrees using a dual digital inclinometer. Postural stability was assessed using a stabilometric force platform, which measured anterior to posterior (A-P) sway, medial to lateral (M-L) sway, and the ellipse area in mm².

RESULTS: The findings of this study revealed a statistically significant and moderate positive correlation between kinesiophobia and lumbar JPS in various directions, including flexion (r = 0.51, P < .001), side-bending to the left (r = 0.37, P = .001), and side-bending to the right (r = 0.34, P = .002). Similarly, a significant positive association was observed between kinesiophobia and postural stability, as indicated by the correlation coefficients: A-P sway (r = .47, P < .001), M-L sway (r = 0.58, P < .001), and ellipse area (r = 0.51, P < .001). Furthermore, the analysis revealed that pain significantly mediated the relationship between kinesiophobia and both lumbar JPS (P < .05) and postural stability (P < .05). These findings were demonstrated through mediation analysis.

CONCLUSIONS: This study identified a significant association between kinesiophobia, lumbar JPS, and postural stability. Additionally, we observed the presence of pain as a potential mediator in this relationship. However, it is important to note that our cross-sectional study design precludes establishing causality or determining the direct mediation effect of pain on adverse outcomes.

The Mediating Effect of Physical Performance on Physical Activity and Mild Cognitive Impairment Among Older Adults With Type 2 Diabetes in Rural China

Int J Geriatr Psychiatry. 2024 Oct;39(10):e70001. doi: 10.1002/gps.70001.

ABSTRACT

OBJECTIVES: To investigate the intermediary role of physical performance in the association between physical activity and mild cognitive impairment (MCI) in older adults with type 2 diabetes mellitus (T2DM), residing in rural areas.

METHODS: This study employed a random sampling method to select 316 patients aged 65 years and older, all diagnosed with T2DM, from 24 different rural areas in China. The relationships between physical activity, physical performance, and MCI were analyzed using a logistic regression model, and the proposed mediation model was validated through bootstrap test.

RESULTS: In this study, the prevalence of MCI in the rural-based older adults with T2DM was 53.48%. A significant correlation was observed between the levels of physical activity and physical performance. Moreover, diminished physical performance was positively correlated with an increased propensity for MCI, even after adjusting for relevant covariates. Physical performance was discerned to exert a partial mediating influence on the relationship between physical activity and MCI.

CONCLUSIONS: The empirical evidence generated by this study posits that the impact of physical activity on MCI is partially mediated through physical performance in an aging population with T2DM residing in rural environments. Consequently, interventional strategies aimed at ameliorating physical performance may serve as a viable approach to mitigate the progression of cognitive decline.
