The usefulness of [99mTc]MIBI scintigraphy in the diagnostic algorithm of ultrasonographical suspected thyroid nodules by using EU-TIRADS criteria

Nucl Med Rev Cent East Eur. 2023;26(0):29-33. doi: 10.5603/NMR.a2023.0002.

ABSTRACT

BACKGROUND: Although not yet involved in the algorithm of thyroid nodules, 99mTc-methoxy-isobutyl-isonitrile ([99mTc]MIBI) scintigraphy may help in the individual diagnostic workup of a thyroid patient, especially where indeterminate fine needle aspiration biopsy (FNAB) is present. The aim of this study was to evaluate the usefulness of [99mTc]MIBI thyroid scintigraphy in the diagnostic algorithm of thyroid nodules, particularly in ultrasound EU-TIRADS 4 or 5 lesions, that cytologically were either indeterminate or benign.

MATERIAL AND M: ETHODS: A retrospective randomized study, including 42 thyroid patients, with mean age 47 ± 17 years, was conducted. [99mTc]MIBI scan was compared with ultrasound (US) EU-TIRADS criteria, pertechnetate scan, FNAB and histopathological findings for the differentiation of malignant thyroid nodules from benign lesions.

RESULTS: The US mainly detected hypoechoic inhomogeneous presentation of the thyroid nodules (35/42, 83.33%), 4 cases with isoechoic nodules and 2 cases presented with hyperechoic thyroid nodules. Histopathology revealed malignancy in 15/42 (35.71%), while all other patients 27/42 (64.29%) were benign. Visual analysis score showed that patients scored with 1+ and 2+ were statistically significant to be benign, while 13 vs. 10 pts that were visual score 3+ were malignant vs. benign (p > 0.05). Sensitivity was 100%, while specificity was very low 22.22%, PPV was 41.67%.

CONCLUSIONS: Even [99mTc]MIBI scan is not routinely used as a daily practice diagnostic tool of thyroid nodules, we will further apply it on a larger group of patients and try to quantify the uptake of the radiotracer to see whether it will help in the diagnostic algorithm of thyroid nodules.

CWAS-Plus: estimating category-wide association of rare noncoding variation from whole-genome sequencing data with cell-type-specific functional data

Brief Bioinform. 2024 May 23;25(4):bbae323. doi: 10.1093/bib/bbae323.

ABSTRACT

Variants in cis-regulatory elements link the noncoding genome to human pathology; however, detailed analytic tools for understanding the association between cell-level brain pathology and noncoding variants are lacking. CWAS-Plus, adapted from a Python package for category-wide association testing (CWAS), enhances noncoding variant analysis by integrating both whole-genome sequencing (WGS) and user-provided functional data. With simplified parameter settings and an efficient multiple testing correction method, CWAS-Plus conducts the CWAS workflow 50 times faster than CWAS, making it more accessible and user-friendly for researchers. Here, we used a single-nuclei assay for transposase-accessible chromatin with sequencing to facilitate CWAS-guided noncoding variant analysis at cell-type-specific enhancers and promoters. Examining autism spectrum disorder WGS data (n = 7280), CWAS-Plus identified noncoding de novo variant associations in transcription factor binding sites within conserved loci. Independently, in Alzheimer’s disease WGS data (n = 1087), CWAS-Plus detected rare noncoding variant associations in microglia-specific regulatory elements. These findings highlight CWAS-Plus’s utility in genomic disorders and scalability for processing large-scale WGS data and in multiple-testing corrections. CWAS-Plus and its user manual are available at https://github.com/joonan-lab/cwas/ and https://cwas-plus.readthedocs.io/en/latest/, respectively.

Human biomonitoring of serum polycyclic aromatic hydrocarbons and oxygenated derivatives by gas chromatography coupled with tandem mass spectrometry

Anal Methods. 2024 Jul 5. doi: 10.1039/d4ay00758a. Online ahead of print.

ABSTRACT

While polycyclic aromatic hydrocarbons (PAHs) are well-known for their potential carcinogenic and mutagenic effects, the health implications of exposure to oxygenated PAHs (OPAHs), which are significant substitutes with increased persistence and bioaccumulation, are less understood. In this work, we compared the background levels of liquid-liquid, solid-phase, and supported-liquid extraction for the determination of serum PAHs and OPAHs. Liquid-liquid extraction demonstrated minimal background interference and was validated and used for human biomonitoring of PAHs and OPAHs in 240 participants using gas chromatography coupled with tandem mass spectrometry. We observed significant positive correlations between these compounds using Spearman correlation analysis. Furthermore, we investigated the concentration levels and compositions of PAHs and OPAHs among different demographic characteristics, including gender, age, and body mass index. Linear regression analysis demonstrated a weak but significant correlation between total concentrations of PAHs and OPAHs and age and body mass index. A multivariate linear regression analysis was then conducted to examine the association of exposure to individual PAHs and OPAHs with the body mass index. Naphthalene exposure and body mass index showed a statistically significant positive correlation, suggesting that higher levels of naphthalene exposure are associated with higher body mass index values. This study establishes a robust method for biomonitoring PAHs and OPAHs in serum, evaluating the exposure levels of these compounds in healthy adults and highlighting their associations with demographic characteristics.

Functional Multivariable Logistic Regression With an Application to HIV Viral Suppression Prediction

Biom J. 2024 Jul;66(5):e202300081. doi: 10.1002/bimj.202300081.

ABSTRACT

Motivated by improving the prediction of the human immunodeficiency virus (HIV) suppression status using electronic health records (EHR) data, we propose a functional multivariable logistic regression model, which accounts for the longitudinal binary process and continuous process simultaneously. Specifically, the longitudinal measurements for either binary or continuous variables are modeled by functional principal components analysis, and their corresponding functional principal component scores are used to build a logistic regression model for prediction. The longitudinal binary data are linked to underlying Gaussian processes. The estimation is done using penalized spline for the longitudinal continuous and binary data. Group-lasso is used to select longitudinal processes, and the multivariate functional principal components analysis is proposed to revise functional principal component scores with the correlation. The method is evaluated via comprehensive simulation studies and then applied to predict viral suppression using EHR data for people living with HIV in South Carolina.

A Mixed-Methods Study to Evaluate Family Planning Desires and Barriers to Building Families Among Gay, Bisexual, and Lesbian Cisgender Military Service Members

Mil Med. 2024 Jul 5:usae327. doi: 10.1093/milmed/usae327. Online ahead of print.

ABSTRACT

INTRODUCTION: Barriers to seeking infertility care for lesbian, gay, bisexual, transgender, intersex, queer/questioning, and asexual (LGBTIQA+) individuals are well documented in the literature. However, little is known about military LGBTIQA+ service members seeking infertility care within the Military Health System. Approximately 6.1% of active duty U.S. service members across all branches identify as LGBTIQA+, which underscores the need for a deeper understanding of the needs of this community to support and retain service members. We therefore sought to describe the lived experiences of lesbian and gay cisgender service members in building their families in order to understand their family-building desires and potential barriers to seeking infertility care.

MATERIALS AND METHODS: We developed a survey to investigate the impact of military service on family planning. After Institutional Review Board approval, we distributed the survey throughout Walter Reed National Military Medical Center’s obstetrics and gynecology clinic and posted the survey on multiple open and closed social media pages for LGBTIQA+ service members. We reported descriptive statistics of our survey and compared binary variables using the Fisher exact test. Following completion of this survey, participants could self-select to participate in semi-structured interviews.

RESULTS: Sixty-eight respondents completed our survey and self-identified as either cis-male (n = 28) or cis-female (n = 40). Most respondents (67.9% cis-males, 92.5% cis-females) plan to build their families during their military commitment; however, approximately half (50.0% cis-male, 42.5% cis-female) reported a lack of support in this endeavor. Many respondents were unaware of resources that would assist in the pursuit of donor egg, donor sperm, or surrogacy (78.6% cis-males, 50.0% cis-females). Thirty-six participants elected to complete a follow-up interview. After coding the interviews, 5 themes emerged: (1) barriers to initiating care; (2) institutional barriers within the military; (3) political barriers; (4) knowledge sharing; and (5) implicit and explicit bias.

CONCLUSIONS: Our results suggest significant barriers to LGBTIQA+ service members seeking infertility care. Overall, LGBTIQA+ service members did not feel supported by the military in building their families. Although the military has expanded access to infertility services, efforts to raise awareness and build support for LGBTIQA+ service members are warranted.

Outcomes of Robotic Transabdominal Retromuscular Repair: 3-Year Follow-up

J Abdom Wall Surg. 2024 Jun 20;3:12907. doi: 10.3389/jaws.2024.12907. eCollection 2024.

ABSTRACT

BACKGROUND: Our study addresses the gap in ventral hernia repair literature, regarding the long-term effectiveness of robotic transabdominal retrorectus umbilical prosthetic repair (r-TARUP) for primary and incisional ventral hernias. This study aimed to report the 3-year recurrence rates and overall patient outcomes including quality of life.

METHOD: A retrospective review of prospective collected data analyzed 101 elective r-TARUP patients from August 2018 to January 2022. Data collected included demographics, hernia sizes, mesh types, postoperative outcomes and the European Hernia Society Quality of Life questionnaire (EuraHS-QoL) before and after surgery.

RESULTS: The average age of the group of patients was 53, having a mean body mass index (BMI) of 32 kg/m, with 54% incisional and 46% primary hernias, with mean length and width of 4.4 cm and 6.1 cm, utilizing synthetic 58% and bioabsorbable 42% mesh types. The majority were classified as Centers of Disease Control and Prevention (CDC) class I wounds. Postoperative complications included seroma (2%), hematoma (3%), which required surgical intervention, with no significant correlation to mesh type. A strong positive correlation was found between Transversus Abdominis Release (TAR) and increased length of hospital stay (correlation coefficient: 0.731, p < 0.001). Preoperative quality of life assessments demonstrated statistically significant improvements when compared to postoperative assessments at 3 years, with a mean (±SD) of 61.61 ± 5.29 vs. 13.84 ± 2.6 (p < 0.001). Mean follow up of 34.4 months with no hernia recurrence at 1 year and 3 recurrence at the 2-3 years follow up (3.2%).

CONCLUSION: The r-TARUP technique has proven to be safe and effective for repairing primary and incisional ventral hernias, with a low recurrence rate during this follow up period with a noticeable improvement in quality of life (QoL).

Guideline-Concordant Therapy for Community-Acquired Pneumonia in the Hospitalized Population: A Systematic Review and Meta-analysis

Open Forum Infect Dis. 2024 Jun 15;11(7):ofae336. doi: 10.1093/ofid/ofae336. eCollection 2024 Jul.

ABSTRACT

BACKGROUND: A commonly used guideline for community-acquired pneumonia (CAP) is the joint American Thoracic Society and Infectious Diseases Society of America practice guideline. We aimed to investigate the effect of guideline-concordant therapy in the treatment of CAP.

METHODS: We systematically searched MEDLINE, Embase, CENTRAL, Web of Science, and Scopus from 2007 to December 2023. We screened citations, extracted data, and assessed risk of bias in duplicate. Primary outcomes were mortality rates, intensive care unit (ICU) admission, and length of stay. Secondary outcomes were guideline adherence, readmission, clinical cure rate, and adverse complications. We performed random-effect meta-analysis to estimate the overall effect size and assessed heterogeneity using the I2 statistics.

RESULTS: We included 17 observational studies and 82 240 patients, of which 10 studies were comparative and pooled in meta-analysis. Overall guideline adherence rate was 65.2%. Guideline-concordant therapy was associated with a statistically significant reduction in 30-day mortality rate (crude odds ratio [OR], 0.49 [95% confidence interval .34-.70; I2 = 60%]; adjusted OR, 0.49 [.37-.65; I2 = 52%]) and in-hospital mortality rate (crude OR, 0.63 [.43-.92]; I2 = 61%). Due to significant heterogeneity, we could not assess the effect of guideline-concordant therapy on length of stay, ICU admission, readmission, clinical cure rate, and adverse complications.

CONCLUSIONS: In hospitalized patients with CAP, guideline-concordant therapy was associated with a significant reduction in mortality rate compared with nonconcordant therapy; however, there was limited evidence to support guideline-concordant therapy for other clinical outcomes. Future studies are needed to assess the clinical efficacy and safety of current guideline recommendations.

Developing a customised set of evidence-based quality indicators for measuring workplace violence towards healthcare workers: a modified Delphi method

BMJ Open Qual. 2024 Jul 4;13(3):e002855. doi: 10.1136/bmjoq-2024-002855.

ABSTRACT

BACKGROUND: Workplace violence (WPV) is a complex global challenge in healthcare that can only be addressed through a quality improvement initiative composed of a complex intervention. However, multiple WPV-specific quality indicators are required to effectively monitor WPV and demonstrate an intervention’s impact. This study aims to determine a set of quality indicators capable of effectively monitoring WPV in healthcare.

METHODS: This study used a modified Delphi process to systematically arrive at an expert consensus on relevant WPV quality indicators at a large, multisite academic health science centre in Toronto, Canada. The expert panel consisted of 30 stakeholders from the University Health Network (UHN) and its affiliates. Relevant literature-based quality indicators which had been identified through a rapid review were categorised according to the Donabedian model and presented to experts for two consecutive Delphi rounds.

RESULTS: 87 distinct quality indicators identified through the rapid review process were assessed by our expert panel. The surveys received an average response rate of 83.1% in the first round and 96.7% in the second round. From the initial set of 87 quality indicators, our expert panel arrived at a consensus on 17 indicators including 7 structure, 6 process and 4 outcome indicators. A WPV dashboard was created to provide real-time data on each of these indicators.

CONCLUSIONS: Using a modified Delphi methodology, a set of quality indicators validated by expert opinion was identified measuring WPV specific to UHN. The indicators identified in this study were found to be operationalisable at UHN and will provide longitudinal quality monitoring. They will inform data visualisation and dissemination tools which will impact organisational decision-making in real time.

Psychometric of the Persian version of Quality of Life in Late-Stage Dementia (QUALID) in the elderly with Alzheimer’s disease

BMJ Open Qual. 2024 Jul 4;13(3):e002673. doi: 10.1136/bmjoq-2023-002673.

ABSTRACT

BACKGROUND: Improving the quality of life (QoL) is a significant healthcare priority, and it is an important health outcome for elderly individuals with Alzheimer’s disease. Quality of Life in Late-Stage Dementia (QUALID) is a specific scale used to measure the QoL in elderly individuals with Alzheimer’s. So far, limited quantitative research has been conducted on the psychometric properties of this scale.

AIMS: This study was conducted to translate the QUALID Scale into Persian and evaluate its psychometric properties among family and professional caregivers of elderly individuals with Alzheimer’s disease in Tehran.

METHODS: A cross-sectional methodological study was conducted among family and professional caregivers of elderly individuals with Alzheimer’s in Tehran, Iran in 2022. The questionnaire was translated into Persian using the forward-backward method. Face and content validity were assessed. Additionally, construct validity was examined using exploratory factor analysis (EFA) with Equamax rotation (n=210) and confirmatory factor analysis (CFA) (n=155). Cronbach’s alpha and interclass correlation coefficient (ICC) were estimated to determine reliability.

RESULTS: A total of 365 caregivers with a mean age of 14.18±42.60 years participated in this study. In the face and content validity phase, all 11 items were retained. To determine the construct validity, two factors were extracted in the EFA phase, including behavioural signs of discomfort and behavioural signs of social interaction. The findings of the CFA also indicated that all goodness of fit indices supported the final model. The Cronbach’s alpha was excellent for both factors (0.814), and the ICC was calculated as 0.98.

CONCLUSION: Based on the findings of this study, it can be concluded that the Persian version of the QUALID Scale has sufficient validity and reliability for measuring the QoL in elderly Iranian individuals with Alzheimer’s.

The effect of an annual temporary abstinence campaign on population-level alcohol consumption in Thailand: a time-series analysis of 23 years

BMJ Glob Health. 2024 Jul 4;9(7):e014428. doi: 10.1136/bmjgh-2023-014428.

ABSTRACT

RATIONALE: A small number of earlier studies have suggested an effect of temporary abstinence campaigns on alcohol consumption. However, all were based on self-reported consumption estimates.

OBJECTIVES: Using a time series of 23-year monthly alcohol sales data, this study examined the effect of an annual temporary abstinence campaign, which has been organised annually since 2003 during the Buddhist Lent period (spanning 3 months), on population-level alcohol consumption.

METHODS: Data used in the analysis included a time series of monthly alcohol sales data from January 1995 to September 2017 and the midyear population counts for those years. Generalised additive models (GAM) were applied to estimate trends as smooth functions of time, while identifying a relationship between the Buddhist Lent abstinence campaigns on alcohol consumption. The sensitivity analysis was performed using a seasonal autoregressive integrated moving average with exogenous variables (SARIMAX) model.

INTERVENTION: The Buddhist Lent abstinence campaign is a national mass media campaign combined with community-based activities that encourages alcohol abstinence during the Buddhist Lent period, spanning 3 months and varying between July and October depending on the lunar calendar. The campaign has been organised annually since 2003.

MAIN OUTCOME: Per capita alcohol consumption using monthly alcohol sales data divided by the midyear total population number used as a proxy.

RESULTS: Median monthly per capita consumption was 0.43 (IQR: 0.37 to 0.51) litres of pure alcohol. Over the study period, two peaks of alcohol consumption were in March and December of each year. The significant difference between before-campaign and after-campaign coefficients in the GAM, -0.102 (95% CI: -0.163 to -0.042), indicated an effect of the campaign on alcohol consumption after adjusting for the time trend and monthly seasonality, corresponding to an average reduction of 9.97% (95% CI: 3.65% to 24.18%). The sensitivity analyses produced similar results, where the campaign was associated with a decrease in consumption of 8.1% (95% CI: 0.4% to 15.7%).

CONCLUSIONS: This study demonstrated that the temporary abstinence campaign was associated with a decrease in population-level alcohol consumption during campaign periods. The finding contributed to a growing body of evidence on the effectiveness of emerging temporary abstinence campaigns.
