Trial-based economic evaluation of the system-integrated activation of community health volunteers in rural Ghana

Glob Health Action. 2023 Dec 31;16(1):2203541. doi: 10.1080/16549716.2023.2203541.

ABSTRACT

BACKGROUND: Globally, steps to revitalise programmes deploying community health workers (CHWs) on a national scale have been growing, but few economic evaluations have been done on system-integrated CHW programmes. Ghana has dual cadres of CHWs: community health officers (CHOs) and community health volunteers (CHVs). CHO plays a major role in primary health services but has suffered from chronic staff shortages. We activated CHVs in communities to mitigate the negative impact due to CHO shortages. The CHVs conducted home visits and provided health education to prevent childhood diseases.

OBJECTIVE: We evaluated the cost-effectiveness and cost-benefit of activating CHVs.

METHODS: In a cluster-randomised trial with 40 communities in rural Ghana, the changes in disease incidence were inferred from a statistical model using a Bayesian generalised linear multilevel model. We evaluated the total incremental cost, benefit, and effectiveness for the intervention from an economic model. In cost-effectiveness analysis, disability-adjusted life years (DALYs) were estimated using a decision tree model. In the cost-benefit analysis, the cost-benefit ratio and net present value of benefit were estimated using a decision tree model, and a standardised sensitivity analysis was conducted. The decision tree model was a one-year cycle and run over 10-years. Costs, benefits, and effectiveness were discounted at a rate of 3% per year.

RESULTS: According to the cost-effectiveness analysis, the programme was highly likely to exceed the WHO-CHOICE threshold (1-3 times GDP per capita), but it was unlikely to exceed the conservative threshold (10-50% of GDP per capita). In the cost-benefit analysis, the mean and median cost-benefit ratios were 6.4 and 4.8, respectively.

CONCLUSION: We found the potential economic strengths in the cost-benefit analysis. To integrate CHW programmes with national health systems, we need more research to find the most effective scope of work for CHWs.

Zhonghua Yu Fang Yi Xue Za Zhi. 2023 May 6;57(5):718-727. doi: 10.3760/cma.j.cn112150-20221112-01103.

ABSTRACT

Objective: To investigate the clinical characteristics of Aspergillus fumigatus(A.f)-sensitized asthma and allergic bronchopulmonary aspergillosis (ABPA), which provides a foundation for the diagnosis and differential diagnosis of A.f-sensitized asthma and ABPA, as well as the prevention of ABPA. Methods: This was a single-center retrospective case-control study. Collected the clinical data of patients who visited the Department of Respiratory and Critical Care Medicine, Zhongnan Hospital of Wuhan University from December 2018 to May 2022.A total of 122 patients were included, including 64 males (52.5%) and 58 females (47.5%).The age range was 3 to 89 years.The median age was 44 years.The average age was 41.8 years.The patients were divided into three groups (48 ABPA, 35 A.f-sensitized asthma and 39 HDM-sensitized asthma).Analyzed the differences and correlations among clinical indicators in the three groups, and evaluated the risk factors for the development of ABPA in A.f-sensitized asthma.For statistical analysis, metrological data was tested by t-test or Wilcoxon Mann-Whitney. Classification variables by chi-square test or Fisher’s exact test. Pearson correlation analysis for normal distribution data.Spearman correlation analysis for skewed distribution data. Influencing factor analysis was performed using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was made, the area under the ROC curve (AUC) was calculated, and the sensitivity and specificity of the model were evaluated. Results: Compared with patients with A.f-sensitized asthma, the fractional exhaled nitric oxide (FeNO) [75.00(52.00, 87.00)ppb vs. 40.00(32.00, 52.00)ppb], eosinophils% (EO%) [10.60(6.75, 13.05) vs. 4.10(1.20, 7.30)], eosinophils (EO) [1.50(1.07, 2.20)×109/L vs. 0.33(0.10, 0.54)×109/L], A.f-specific Immunoglobulin E (sIgE) [10.24(4.09, 22.88)KU/L vs. 1.13(0.53, 3.72) KU/L], and sIgE to total IgE(tIgE) ratio (sIgE/tIgE) [0.0049(0.0027, 0.0100) vs. 0.0008(0.0004, 0.0017)] were higher in ABPA patients, the differences were statistically significant (P<0.001). In all patients, tIgE was positively correlated with EO% (r=0.206, P<0.05) and EO (r=0.302, P<0.001). sIgE/tIgE was negatively correlated with one-second rate (FEV1/FVC%) (r=-0.256, P<0.01). The percentage of predicted forced vital capacity [FVC(%)] was negatively correlated with FeNO (r=-0.184, P<0.05).In the ABPA group, the percentage of predicted peak expiratory flow [PEF(%)] was negatively correlated with FeNO (r=-0.295, P<0.05). In the HDM-sensitized asthma group, FeNO was positively correlated with EO% (r=0.49, P<0.01) and EO (r=0.548, P<0.001).The results of logistic regression analysis showed that FeNO and EO were the influencing factors for the development of ABPA in A.f-sensitized asthma. ROC curve analysis results showed that A.f-sIgE (cut-off, 4.108; AUC=0.749;95%CI, 0.632-0.867), sIgE/tIgE(cut-off, 0.0026;AUC=0.749;95%CI, 0.631-0.868), FeNO(cut-off, 55.5;AUC=0.794; 95%CI, 0.687-0.900), EO% (cut-off, 8.70;AUC=0.806;95%CI, 0.709-0.903) and EO (cut-off, 0.815;AUC=0.865;95%CI, 0.779-0.950) had differential diagnostic value in A.f-sensitized asthma and ABPA.The combination of FeNO, EO and EO% had good diagnostic efficiency in differentiating A.f-sensitized asthma from ABPA, with a sensitivity of 91.4% and a specificity of 84.4%. Conclusion: Compared with patients with A.f-sensitized asthma, patients with ABPA have more severe eosinophil inflammation. The higher the FeNO and EO, the more likely A.f-sensitized asthma will develop into ABPA.sIgE/tIgE may have differential diagnostic value in A.f-sensitized asthma and ABPA.The combination of FeNO, EO and EO% has good diagnostic efficacy in differentiating A.f-sensitized asthma from ABPA.

Burden of non-communicable diseases attributable to population aging in China, 1990‒2050

Zhonghua Yu Fang Yi Xue Za Zhi. 2023 May 6;57(5):667-673. doi: 10.3760/cma.j.cn112150-20220531-00552.

ABSTRACT

Objective: The direction and intensity of population aging on the burden of non-communicable diseases (NCDs) in China from 1990 to 2019 were analyzed, and the burden of NCDs in 2050 was predicted. Methods: The disease-specific disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) in the Chinese population from 1990 to 2019 were obtained from the Global Burden of Disease Study.The differences in indicators from 1990 to 2019 were attributed to the contribution of age structure, population size, and all other causes. The Bayesian age-time-cohort models were used to predict DALYs from NCDs to 2050. Results: The absolute level of DALYs caused by NCDs increased by 7.460 million from 1990 to 2019, and the age structure contributed 186.0% (95% Uncertainty Intervals (UIs): 178.4%-193.6%), population size contributed 77.0% (95% UIs: 69.5%-80.8%), all other causes contributed -163.0% (95% UIs:-163.1%- -159.3%). DALYs caused by NCDs consist of 2.527 million YLLs and 4.934 million YLDs, in which the contribution of age structure to YLLs and YLDs was 414.6% (95% UIs: 396.2%-432.5%) and 69.1% (95% UIs: 66.7%-71.4%), respectively. From 2019 to 2050, the diseases with increased DALYs due to changes in age structure are cardiovascular diseases, neoplasms, chronic respiratory diseases, neurological disorders, sense organ diseases, diabetes and kidney diseases, musculoskeletal disorders, digestive diseases, mental disorders, and skin and subcutaneous diseases in descending order. Conclusions: From 1990 to 2019, except for skin and subcutaneous diseases, the burden of other NCDs attributable to population aging increased, mainly due to disability. By 2050, the burden of NCDsattributable to population aging will continue to rise.

Association of greenness, nitrogen dioxide with the prevalence of hypertension among the elderly over 65 years old in China

Zhonghua Yu Fang Yi Xue Za Zhi. 2023 May 6;57(5):641-648. doi: 10.3760/cma.j.cn112150-20230118-00044.

ABSTRACT

Objective: To investigate the association of mixed exposure to greenness and nitrogen dioxide(NO2) and hypertension among the older adults aged 65 years and over in China. Methods: The study subjects were from the Chinese Longitudinal Healthy Longevity Survey from 2017 to 2018. A total of 15 423 older adults aged 65 years and over meeting the criteria were finally included in the study. A questionnaire survey was used to collect information on demographic characteristics, lifestyle habits and self-reported prevalence of hypertension. Blood pressure values were obtained through physical examination. The level of normalized difference vegetation index(NDVI) was measured by the Medium-resolution Imaging Spectral Radiator(MODIS) of the National Aeronautics and Space Administration(NASA). The concentration of NO2 was from China’s surface air pollutant data set. Meteorological data was from NASA MERRA-2. The exposure to NDVI and NO2 for each study subject was calculated based on the area within a 1 km radius around their residence. The association between mixed exposure of NDVI and NO2 as well as their interaction and hypertension in older adults was analyzed by using the multivariate logistic regression model. The restrictive cubic spline(RCS) function was used to explore the exposure-response relationship between greenness and NO2 and the risk of hypertension in study subjects. Results: The mean age of 15 423 older adults were (85.6±11.6). Women accounted for 56.3%(8 685/15 423) and 55.6%(8 578/15 423) lived in urban areas. The mean time of residence was (60.9±28.5) years. 59.8% of participants were with hypertension. The mean NDVI level was 0.41±0.13, and the mean NO2 concentration was (32.18±10.36) μg/cm3. The results of multivariate logistic regression analysis showed that NDVI was inversely and linearly associated with the hypertension in older adults, with the OR(95%CI) value of 0.959(0.928-0.992). Compared with the T1 group of NDVI, the risk of hypertension was lower in the T3 group, with the OR(95%CI) value of 0.852(0.769-0.944), and the trend test was statistically significant(P<0.05). Compared with the T1 group of NO2, the risk of hypertension was higher in the T2 and T3 groups, with OR(95%CI) values of 1.160(1.055-1.275) and 1.244(1.111-1.393), and the trend test was statistically significant (P<0.05). The result of the RCS showed that NDVI was inversely and linearly associated with hypertension in older adults. NO2 was nonlinearly associated with hypertension in older adults. The interaction analysis showed that NDVI and NO2 had a negative multiplicative interaction on the risk of hypertension, with OR(95%CI) value of 0.995(0.992-0.997). Conclusion: Exposure to greenness and NO2 are associated with hypertension in older adults.

GADD45B predicts lung squamous cell carcinoma survival and impacts immune infiltration, and T cell exhaustion

Autoimmunity. 2023 Dec;56(1):2209706. doi: 10.1080/08916934.2023.2209706.

ABSTRACT

BACKGROUND: This study focussed on exploring the prognostic prediction performance of the growth arrest and DNA damage-inducible 45 beta (GADD45B) and its associations with T-cell activity and immune soakage in different malignancies, especially lung squamous cell carcinoma (LUSC).

METHODS: We applied TIMER database for comparing the expressions of GADD45B among different cancers. OncoLnc, Gene Expression Profiling Interactive Analysis 2 (GEPIA2), and Kaplan-Meier Plotter were utilised to evaluate the prognostic prediction performance of GADD45B. Besides, the associations of GADD45B with clinical stage, associated gene markers, and immune infiltration were examined through TISIDB, GEPIA2, and Tumour Immune Estimation Resource (TIMER). Biological processes (BPs) and KEGG enrichment analyses were performed to illustrate the possible role of GADD45B in LUSC. The miRWalk database was adopted to analyse the gene miRNA interaction network of GADD45B in LUSC.

RESULTS: GADD45B expression was decreased in most of the malignancies, with relation to the poor prognosis in LUSC. GADD45B also significantly affected the survival of LUSC subgroups divided by clinic data. GADD45B significantly correlates with and may stimulate T cell exhaustion in LUSC.

CONCLUSIONS: GADD45B is a prognostic indicator in multiple tumours, especially in LUSC. Moreover, modulating GADD45B expression may improve immunotherapy efficacy in LUSC.

Characterizing opioid use in a Dutch cohort with migraine

Cephalalgia. 2023 May;43(5):3331024231174160. doi: 10.1177/03331024231174160.

ABSTRACT

BACKGROUND: There is lack of data on opioid (over)use for migraine in Europe.

METHODS: We performed a cross-sectional study in a large Dutch cohort using a web-based questionnaire to assess opioid use in individuals with migraine. Primary outcome was to assess opioid use for the treatment of migraine attacks. As secondary outcomes we specified use of opioids (duration of use, type of opioids, prescriber) and compared between persons with episodic migraine versus chronic migraine. Descriptive statistics, unpaired T-tests, Chi-square and Mann-Whitney U tests were used.

RESULTS: In total n = 3712 patients participated, 13% ever used opioids for headache. In opioid users, 27% did this for >1 month, and 11% for >1 year, and 2% without prescription. The majority of prescribing physicians were general practitioners (46%), followed by neurologists (35%), other specialists (9%), or emergency room doctors (8%). Opioids were used as acute treatment in 63%, in 16% as preventive treatment, and in 21% for both indications. Chronic migraine patients reported more opioid use compared with episodic migraine (22% versus 12%, p < 0.001), with also more prolonged use (>1 month: 34% chronic migraine versus 24% episodic migraine, p < 0.003).

CONCLUSION: Opioid use is more frequent and prolonged in chronic migraine patients. Further education for both doctors and migraine subjects and providing multimodal pain management strategies are needed to reduce opioid use in persons with migraine.

Proof-of-concept study of artificial intelligence-assisted review of CBCT image guidance

J Appl Clin Med Phys. 2023 May 10:e14016. doi: 10.1002/acm2.14016. Online ahead of print.

ABSTRACT

PURPOSE: Automation and computer assistance can support quality assurance tasks in radiotherapy. Retrospective image review requires significant human resources, and automation of image review remains a noteworthy missing element in previous work. Here, we present initial findings from a proof-of-concept clinical implementation of an AI-assisted review of CBCT registrations used for patient setup.

METHODS: An automated pipeline was developed and executed nightly, utilizing python scripts to interact with the clinical database through DICOM networking protocol and automate data retrieval and analysis. A previously developed artificial intelligence (AI) algorithm scored CBCT setup registrations based on misalignment likelihood, using a scale from 0 (most unlikely) through 1 (most likely). Over a 45-day period, 1357 pre-treatment CBCT registrations from 197 patients were retrieved and analyzed by the pipeline. Daily summary reports of the previous day’s registrations were produced. Initial action levels targeted 10% of cases to highlight for in-depth physics review. A validation subset of 100 cases was scored by three independent observers to characterize AI-model performance.

RESULTS: Following an ROC analysis, a global threshold for model predictions of 0.87 was determined, with a sensitivity of 100% and specificity of 82%. Inspecting the observer scores for the stratified validation dataset showed a statistically significant correlation between observer scores and model predictions.

CONCLUSION: In this work, we describe the implementation of an automated AI-analysis pipeline for daily quantitative analysis of CBCT-guided patient setup registrations. The AI-model was validated against independent expert observers, and appropriate action levels were determined to minimize false positives without sacrificing sensitivity. Case studies demonstrate the potential benefits of such a pipeline to bolster quality and safety programs in radiotherapy. To the authors’ knowledge, there are no previous works performing AI-assisted assessment of pre-treatment CBCT-based patient alignment.

Visual alertness and brain diffusion tensor imaging at term age predict neurocognitive development at preschool age in extremely preterm-born children

Brain Behav. 2023 May 10:e3048. doi: 10.1002/brb3.3048. Online ahead of print.

ABSTRACT

INTRODUCTION: Cognitive development is characterized by the structural and functional maturation of the brain. Diffusion-weighted magnetic resonance imaging (dMRI) provides methods of investigating the brain structure and connectivity and their correlations with the neurocognitive outcome. Our aim was to examine the relationship between early visual abilities, brain white matter structures, and the later neurocognitive outcome.

METHODS: This study included 20 infants who were born before 28 gestational weeks and followed until the age of 6.5 years. At term age, visual alertness was evaluated and dMRI was used to investigate the brain white matter structure using fractional anisotropy (FA) in tract-based spatial statistics analysis. The JHU DTI white matter atlas was used to locate the findings. The neuropsychological assessment was used to assess neurocognitive performance at 6.5 years.

RESULTS: Optimal visual alertness at term age was significantly associated with better visuospatial processing (p < .05), sensorimotor functioning (p < .05), and social perception (p < .05) at 6.5 years of age. Optimal visual alertness related to higher FA values, and further, the FA values positively correlated with the neurocognitive outcome. The tract-based spatial differences in FA values were detected between children with optimal and nonoptimal visual alertness according to performance at 6.5 years.

CONCLUSION: We provide neurobiological evidence for the global and tract-based spatial differences in the white matter maturation between extremely preterm children with optimal and nonoptimal visual alertness at term age and a link between white matter maturation, visual alertness and the neurocognitive outcome at 6.5 years proposing that early visual function is a building block for the later neurocognitive development.

Satellite Rod Fixation around Rod-fracture Area in Revision Surgery after Three-column Osteotomy for Severe Kyphoscoliosis

Orthop Surg. 2023 May 10. doi: 10.1111/os.13738. Online ahead of print.

ABSTRACT

OBJECTIVE: Three-column osteotomy (3CO) is considered valuable and increasingly utilized in the surgical treatment of severe spine deformity while associated with high implant-related complications and revision risks. This study aims to evaluate the feasibility and clinical outcomes of satellite rod fixation used around the rod-fracture area in revision surgery due to rod fracture after 3CO.

METHODS: Twenty-five patients applying satellite rod fixation in revision surgery from August 2012 to May 2016 were retrospectively reviewed as the SR group. Patients undergoing revision surgery with traditional strategy after 3CO due to rod-fracture were selected as the TR group. Cobb angle, distance between C7 plumb line and center sacral vertical line (C7 PL-CSVL), global kyphosis (GK) and sagittal vertical axis (SVA) were assessed. Patients were required to fulfill the Scoliosis Research Society-22 questionnaire (SRS-22) at pre-revision and the last follow-up. The paired t test was used to analyze the difference among pre-revision, post-revision and last follow-up.

RESULTS: There was no statistical difference in terms of age, gender, body mass index (BMI), fusion level at 1st surgery, and follow-up period between SR and TR group (all P > 0.05). The operation time (1.5 ± 0.7 h vs 3.2 ± 0.9 h, P < 0.001) and intraoperative blood loss (178 ± 51 mL vs 324 ± 96 mL, P < 0.001) were significantly higher in the TR group. Patients in both groups obtained obvious deformity correction after revision surgery. For patients in SR group, the coronal Cobb angle significantly improved from 27.9 ± 21.5° at pre-revision to 21.8 ± 16.6° at post-revision (P = 0.034). The C7 PL-CSVL decreased from 22.6 ± 14.3 mm to 21.3 ± 10.9 mm (P = 0.719). Similarly, improvement was attained in post-revision GK (25.8 ± 17.0° vs 20.2 ± 15.1°, P = 0.061). SVA was corrected from 35.6 ± 33.9 mm to 30.8 ± 24.3 mm after revision (P = 0.182). At the last follow-up, no significant correction loss was observed in both coronal and sagittal parameters (all P > 0.05). All patients responded to the SRS-22 questionnaire and all the domains showed improvements in different levels. As compared to the TR group, the SR group had significantly better pain and management satisfaction scores (all P < 0.05). Additionally, there was no reoccurrence of implant failure during follow-up and all patients achieved solid bony fusion in SR group.

CONCLUSION: Satellite rod fixation around rod-fracture area is indicated for patients in the requirement of revision surgeries due to rod fracture after 3CO. Compared with traditional revision strategies, revision surgery with satellite rods, if patients are selected adequately, is a simpler procedure with less intraoperative blood loss and shorter operating time.
