Novel Generative Recurrent Neural Network Framework to Produce Accurate, Applicable, and Deidentified Synthetic Medical Data for Patients With Metastatic Cancer

JCO Clin Cancer Inform. 2023 May;7:e2200125. doi: 10.1200/CCI.22.00125.

ABSTRACT

PURPOSE: Sensitive patient data cannot be easily shared/analyzed, severely limiting the innovative progress of research, specifically for marginalized/under-represented populations. Existing methods of deidentification are subject to data breaches. The objective of this study was to develop a neural network capable of generating a synthetic version of data for patients with novel postoperative metastatic cancer.

METHODS: We analyzed a metastatic cancer patient cohort of 167,474 patients obtained from the National Surgical Quality Improvement Program. Twenty-seven clinical features were analyzed. We created a volume-matched synthetic cohort of 167,474 patients and a reduced-size synthetic cohort of 5,000 patients. The volume-matched and reduced-size synthetic cohorts were compared against the ground truth data to analyze differences in principal component distribution, underlying statistical properties/associations, intervariable correlations, and machine learning classifier performance when developed on the synthetic data.

RESULTS: Among 167,474 patients with metastatic cancer in the original data, 50,669 (30.3%) died within 30 days of their index surgery. Our model was able to accurately capture underlying statistical properties, principal components, and intervariable correlations within the ground truth data, yielding an accuracy of 93.2% with a loss of 0.21%, and develop synthetic data capable of training accurate machine learning classifiers. The reduced-size synthetic data accurately replicated all categorical variables and every continuous variable with statistically similar records (P > .05), with the sole exception of preoperative albumin (P < .05). The volume-matched synthetic data frame was able to accurately replicate all categorical variables (P > .05).

CONCLUSION: This described methodology can be applied to any structured medical data from any setting, significantly expedite scientific analysis/innovation, and be used to develop improved predictive classifiers with boosted tree-based algorithms, serving as the potential new gold standard of medical data sharing and data augmentation.

Effectiveness of nurse-led interventions versus usual care to manage hypertension and lifestyle behaviour: a systematic review and meta-analysis

Eur J Cardiovasc Nurs. 2023 May 3:zvad040. doi: 10.1093/eurjcn/zvad040. Online ahead of print.

ABSTRACT

AIM: This review aimed to investigate the effectiveness of nurse-led interventions versus usual care on hypertension management, lifestyle behaviour, and patients’ knowledge of hypertension and associated risk factors.

METHODS: A systematic review with meta-analysis was conducted following Joanna Briggs Institute (JBI) guidelines. MEDLINE (Ovid), Emcare (Ovid), CINAHL (EBSCO), Cochrane library and ProQuest (Ovid) were searched from inception to 15th of February 2022. Randomised controlled trials (RCTs) examining the effect of nurse-led interventions on hypertension management were identified. Title and abstract, and full text screening, assessment of methodological quality, and data extraction were conducted by two independent reviewers using JBI tools. A statistical meta-analysis was conducted using STATA version 17.0.

RESULTS: A total of 37 RCTs and 9,731 participants were included. The overall pooled data demonstrated that nurse-led interventions may reduce systolic blood pressure (Mean difference -4.66; 95% CI -6.69, -2.64; I2= 83.32; 31 RCTs; low certainty evidence) and diastolic blood pressure (Mean difference -1.91; 95% CI -3.06, -0.76; I2 = 79.35; 29 RCTs; low certainty evidence) compared to usual care. The duration of interventions contributed to the magnitude of blood pressure reduction. Nurse-led interventions had a positive impact on lifestyle behaviour and effectively modified diet and physical activity, but the effect on smoking and alcohol consumption was inconsistent.

CONCLUSION: This review revealed beneficial effects of nurse-led interventions in hypertension management compared to usual care. Integration of nurse-led interventions in routine hypertension treatment and prevention services could play an important role in alleviating the rising global burden of hypertension.

The Effect of a Group Physical Activity Program on Behavior of Incarcerated Youth

J Correct Health Care. 2023 May 2. doi: 10.1089/jchc.22.05.0038. Online ahead of print.

ABSTRACT

Behavioral health challenges are more prevalent in incarcerated youth than in the general youth population. Questions remain regarding whether physical activity programs can reduce behavioral health challenges in incarcerated youth. Data were available for 1,285 youths incarcerated between January 2017 and December 2018. The structured exercise program was implemented in January 2018. Primary outcomes were numbers of use of force (UoF) and of program modifications (PMs) indicative of delinquent behavior in pre- and post-exercise implementation periods. Rates per 1,000 person-days for UoF (10.0 in 2017 vs. 7.4 in 2018) and for PMs (36.7 vs. 22.9) were statistically different. For youths incarcerated both years, rates per 1,000 person-days for UoF (12.3 vs. 7.9), and for PMs (43.3 vs. 23.5) were statistically different. There was a reduction in behavior modifications in incarcerated youths after implementing the exercise program, but further studies are needed to confirm these results.

The influence of interventional measures on metabolic factors in fluoride and aluminum combined poisoning bones

Biotechnol Genet Eng Rev. 2023 May 2:1-12. doi: 10.1080/02648725.2023.2207925. Online ahead of print.

ABSTRACT

This study aimed to evaluate the effects of soybean, selenium and spirulina on bone metabolic factors in rats with combined fluoride and aluminum poisoning.Methods:Sixty SD rats were allocated to five groups: A control group, a high-fluoride aluminum group, a high-fluoride aluminum plus soybean group, a high-fluoride aluminum plus selenium group, and a high-fluoride aluminum plus spirulina group. Serum samples were collected and radioimmunoassay (RIA) was used to measure osteocalcin (BGP), calcitonin (CT), parathyroid hormone (PHT) and insulin growth factor I (IGF-1) levels after 90 and 165 days of intervention. 1. When comparing the serum BGP level in the high-fluorine aluminum plus selenium group with the high-fluorine aluminum group, suggesting that the addition of selenium intervention was beneficial in reducing the effect of high-fluorine aluminum on bone homeostasis. 2. After 90 days and 165 days, the difference in serum CT levels between the intervention group and the control group was not statistically significant, suggesting an effect of the intervention factors.3. After 90 days of exposure, the three intervention groups had lower serum PTH levels (p < 0.00), inferring the efficacy of the interventions.4. After 90 days, serum IGF-1 levels were elevated in the Spirulina group compared with the high-fluorinated aluminum group, and the difference was statistically significant, suggesting that the addition of Spirulina intervention may counteract the inhibition of bone growth by high-fluorinated aluminum. The intervention of soybean, selenium, and spirulina can counterbalance the effects of fluoride and aluminum on bone metabolism and slow down the process of bone turnover.

Nutrigonometry I: Using Right-Angle Triangles to Quantify Nutritional Trade-Offs in Performance Landscapes

Am Nat. 2023 May;201(5):725-740. doi: 10.1086/723599. Epub 2023 Mar 22.

ABSTRACT

AbstractAnimals regulate their food intake to maximize the expression of fitness traits but are forced to trade off the optimal expression of some fitness traits because of differences in the nutrient requirements of each trait (“nutritional trade-offs”). Nutritional trade-offs have been experimentally uncovered using the geometric framework for nutrition (GF). However, current analytical methods to measure such responses rely on either visual inspection or complex models of vector calculations applied to multidimensional performance landscapes, making these approaches subjective or conceptually difficult, computationally expensive, and, in some cases, inaccurate. Here, we present a simple trigonometric model to measure nutritional trade-offs in multidimensional landscapes (nutrigonometry) that relies on the trigonometric relationships of right-angle triangles and thus is both conceptually and computationally easier to understand and use than previous quantitative approaches. We applied nutrigonometry to a landmark GF data set for comparison of several standard statistical models to assess model performance in finding regions in the performance landscapes. This revealed that polynomial (Bayesian) regressions can be used for precise and accurate predictions of peaks and valleys in performance landscapes, irrespective of the underlying structure of the data (i.e., individual food intakes vs. fixed diet ratios). We then identified the known nutritional trade-off between life span and reproductive rate in terms of both nutrient balance and concentration for validation of the model. This showed that nutrigonometry enables a fast, reliable, and reproducible quantification of nutritional trade-offs in multidimensional performance landscapes, thereby broadening the potential for future developments in comparative research on the evolution of animal nutrition.

Comparative Immunohistochemical Analysis of Macrophage Phenotypes in Cutaneous Sarcoid Granuloma, Suture Granuloma, and Lipogranuloma

Am J Dermatopathol. 2023 May 2. doi: 10.1097/DAD.0000000000002446. Online ahead of print.

ABSTRACT

Granulomas are composed of a heterogeneous population of resident and recruited macrophages according to the type of lesion, extent of injury, and local tissue environment (eg, involved site and interaction with infiltrating lymphocytes). Although macrophage phenotypes in various types of granulomas have been previously described, the experimental conditions varied across studies, precluding a comparative and comprehensive understanding of granulomas. This study was conducted to comparatively analyze the expression of markers of the M1 and M2 phenotypes in macrophages that compose various types of granulomas, including epithelioid lesions, under strict conditions. Surgical specimens of cutaneous sarcoidosis (11 lesions), suture granuloma (10 lesions), and subcutaneous lipogranuloma (12 lesions) were immunohistochemically stained for CD11c, CD206, CD163, and CD10. The expression of these markers in macrophages composing each type of granuloma was scored and statistically analyzed. Granuloma macrophages were mostly immunoreactive for CD11c and CD206 in all the examined cases, although many intermingling CD206-negative cells were observed in 5 cases of lipogranuloma. CD163 and CD10 were diffusely expressed in macrophages composing suture granuloma and lipogranuloma, whereas they were not expressed in epithelioid cells in cutaneous sarcoidosis. Meanwhile, “interstitial” macrophages around epithelioid granulomas revealed moderate to marked CD163 expression in 7 lesions of cutaneous sarcoidosis. These results indicate significant differences of expression of CD163 and CD10 between cutaneous sarcoidosis and suture granuloma/lipogranuloma; CD163 and CD10 are downregulated after the epithelioid transformation of macrophages in cutaneous sarcoidosis.

Molecular characterization of rotavirus in oysters from Oualidia lagoon in Morocco

Cell Mol Biol (Noisy-le-grand). 2022 Dec 31;68(12):12-16. doi: 10.14715/cmb/2022.68.12.3.

ABSTRACT

Group A rotavirus (RVA) is the most important foodborne pathogen and is transmitted by oysters. The purpose of this study was to monitor and evaluate the prevalence of RVA in oysters collected in Oualidia Lagoon, Morocco from March 2018 to March 2019 and its relationship to watershed contribution. To achieve this, 312 oysters from 26 lots were collected and tested for viral contamination using real-time polymerase chain reaction. The results showed that 46.15% of the tested samples were positive for RVA. The seasonal distribution of RVA was statistically significant. This is a warning signal against the potential health risks in this oyster growing area, following the consumption of oysters contaminated with RVA, which presents a huge threat to human health resulting in serious illnesses of gastroenteritis.

Impact evidence of the vitamin D status in hypertensive patients in Morocco

Cell Mol Biol (Noisy-le-grand). 2022 Dec 31;68(12):21-25. doi: 10.14715/cmb/2022.68.12.5.

ABSTRACT

Vitamin D deficiency is a hot topic as it affects about 50% of the world’s population. Beyond its extra-osseous effects, notably on the cardiovascular system. In recent years many epidemiological studies have looked at the role of vitamin D status in modulating blood pressure. It appears that there is an inverse association between serum vitamin D levels and blood pressure. It is in this context that our prospective study on the Moroccan population allows having global knowledge of the association between vitamin D and arterial hypertension. This is a descriptive study of vitamin D status in Moroccan hypertensive patients in whom blood samples were taken for serum 25(OH)D determination. The data collected were anonymised and entered into SPSS software. X2 and ANOVA tests were used to investigate the existence of correlations between vitamin D status and age, age at menopause, body mass index, sex and hypertension. 1015 hypertensive patients were included in this study with a female predominance of 84.2%, mainly over 50 years old in 80.8%, of whom 31.5% were overweight or obese, 13.2% had a hypertensive parent and 70.8% had vitamin D deficiency. Vitamin D regulates at least 3% of the human genome with receptors throughout the body, including vascular smooth muscle cells, vascular endothelium and cardiomyocytes, where it acts by vasodilation and by blocking the renin-angiotensin-aldosterone system (RAAS) to lower blood pressure. There is a relationship between low serum vitamin D levels and high blood pressure. Our study concluded that there is an association between hypovitaminosis D and the pathology of hypertension. However, further randomised studies are needed and in the meantime, clinicians could propose it in the therapeutic arsenal of Moroccan hypertensive patients.

Predictors of homebirth amidst COVID-19 pandemic among women attending health facilities in Wondo Genet, Sidama Region, Ethiopia: A case control study

PLoS One. 2023 May 2;18(5):e0283547. doi: 10.1371/journal.pone.0283547. eCollection 2023.

ABSTRACT

BACKGROUND: In developing countries, home delivery increases the risk of maternal and perinatal mortality. Despite this, home deliveries account for a considerable share of deliveries in developing nations such as Ethiopia. Evidence on factors that affect homebirth is required for the measures needed to overcome these conditions.

OBJECTIVE: To identify predictors of homebirth among women attending health facilities in Wondo Genet, Sidama Region.

METHODS: Unmatched case-control study was conducted from May to June 2021 among 308 mothers (102 cases and 206 controls) who recently delivered and visited either postnatal care or sought immunization service at public health facilities of Wondo Genet. A structured interviewer-administered questionnaire was used to collect data. Epi-Data version 3.1 was used for data entry, and the Statistical Package for the Social Sciences (SPSS) version 20 was used for data analysis. Bivariate and multivariate logistic regression analyses were used to identify the determinants of homebirth. The association between the outcome variable and independent variables was declared statistically significant at a P-value < 0.05 with a 95% Confidence Interval (CI) in a multivariable model.

RESULTS: Rural residence [AOR: 3.41; 95%CI: 1.58-7.39], lifetime physical IPV [AOR: 2.35; 95%CI: 1.06-5.17], grand-multiparity [AOR: 5.36; 95%CI: 1.68-17.08], non-use of contraception before recent pregnancy [AOR: 5.82; 95%CI: 2.49-13.60], >30 min to reach health facility [AOR: 2.14; 95%CI: 1.02-4.51], and lack of facemask [AOR: 2.69; 95%CI: 1.25-5.77] were statistically significant predictors of homebirth.

CONCLUSION AND RECOMMENDATION: The access gap to maternity services should be narrowed between rural and urban women. Healthcare programs concerning women’s empowerment could help reduce persistent intimate partner violence. Family planning needs to be promoted, and multiparous women should be counseled on the adverse obstetric consequences of homebirth. The devastating effect of the coronavirus disease 2019 pandemic on maternity services should be prevented.
