ABSTRACT

In conditions of persisting high morbidity of COVID-19, issues related to prompt and timely medical care of population remains actual ones. The purpose of the study to analyze activities of the call-center of the Ministry of Health Care of the Udmurt Republic related to organization of medical care of COVID-19 patients in the Udmurt Republic.

MATERIALS AND METHODS: The statistical (descriptive statistics) and descriptive methods were applied. The indicators of functioning of the call-center of the Ministry of Health Care of the Udmurt Republic in 2020-2022 were analyzed. The psychological characteristics of telephone counseling were studied. The satisfaction of medical organizations and citizens with services of call-center operators was assessed.

THE RESULTS: The main principles of telephone counseling are confidentiality, maintenance of framework of working conversation, respect to personality of addressee. In 2020 the call center phone line received 34160 calls, in 2021 – 128339 calls, in 2022 – 65618 calls. In 25 months of operation the call-center operators received 228,117 calls from citizens related to issues of new coronavirus infection. The number of patient calls to the hot-line increases significantly when incidence of new coronavirus infection increases (r=0.885; p<0.05). Most frequently (25.1%) citizens contacted the call-center of the Ministry of Health Care of the Udmurt Republic due to inability to reach the polyclinic and on issues related to primary before-doctor care. The second place in terms of frequency (18.5%) took issues related to PCR-test results. The third place (14.1%) took issues related to duration of quarantine for patients and persons residing with them, possibility for children to attend preschool and educational institutions. The number of outgoing calling in 2020 was 16146, in 2021 – 89269 and in 2022 9936 calls. During 25 months of operation, call-center operators made 204,782 calls to citizens to monitor their health status and invite them to vaccinations and health screenings. More than half of outgoing calls (58.3%) were related to audio-monitoring of patients undergoing outpatient treatment with making-up of electronic protocol.

CONCLUSIONS: During the period of increasing of COVID-19 morbidity, the call-center becomes an independent structural unit of organizing patient care. The medical organizations and citizens are satisfied with functioning of the call-center of the Ministry of Health Care of the Udmurt Republic organized in order of improving the organization of medical care of patients with COVID-19.

ABSTRACT

BACKGROUND: Opioid-induced constipation (OIC) is a well-known phenomenon, although there is limited literature evaluating the incidence of OIC in children admitted to the pediatric intensive care unit (PICU). The primary aim of this study was to determine the incidence of OIC in the PICU and to determine if it is associated with a higher rate of morbidities or prolonged length of stay (LOS).

METHODS: We conducted a single-center retrospective chart review from July 1, 2014, to June 30, 2015, in our PICU. We included all patients 18 years and younger with a PICU stay of at least 96 hours, who received opioids during their admission. Data were collected on frequency of bowel movements and characteristics of opioid administration. Demographic and clinical data were obtained from Virtual PICU System, LLC.

RESULTS: Of the 94 patients who met study criteria, 39.4% developed constipation. These patients tended to be older (p=0.06) and were noted to weigh more (p=0.03). There was no significant difference in the total or median daily doses, duration of opioid treatment, or mode of administration. Constipation rates did not differ by severity of illness. There was a higher incidence of constipation in the patients who were admitted for neurological issues, or after trauma or abdominal surgery (p=0.002). Patients with constipation had longer LOS than patients without constipation, but the difference was not statistically significant.

CONCLUSION: These results indicate that opioid use is not the sole risk factor for constipation in the PICU setting. This article is protected by copyright. All rights reserved.

ABSTRACT

AIMS: The study aims to identify and compare health indicators collected by national research in Spain and in Brazil that can generate action strategies for health promoting universities.

METHODS: This is an epidemiological, descriptive, cross-sectional study that uses the database of the Secretariat of Health Surveillance of the Brazilian Ministry of Health and the database of the National Statistics Institute of Spain. Based on the National Health Promotion Policy, the analyzer axis prioritizes defined themes; percentage of physical exercise, daily smokers, sedentary lifestyle, obesity and self-perception of health status were evaluated. The data were collected from 2014 to 2020.

RESULTS: In Brazil, physical exercise is the highest percentage indicator, whereas in Spain, sedentary lifestyle is the highest. Regarding the age group, Brazil presented the lowest prevalence of daily smokers in the age group from 18 to 24, with little increase in older age groups; in Spain, older age groups presented the highest rates of sedentary lifestyle and obesity. In 2020, 4.5% of Brazilians reported a negative self-perception of health and in Spain 6.6%.

CONCLUSION: The indicators ‘physical exercise’, ‘daily smokers’ and ‘sedentary lifestyle’ presented better results in Brazil than in Spain. Brazil presents a better perspective on health when compared with Spain, as the results showed that older ages present higher rates of sedentary lifestyle and obesity. Our study results also show that Brazilians report better self-perception in health, which can be interpreted by health promotion strategies.

ABSTRACT

To control genetic background and early life milieu in genome-wide DNA methylation analysis for blood lipids, we recruited Chinese discordant monozygotic twins to explore the relationships between DNA methylations and total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG). 132 monozygotic (MZ) twins were included with discordant lipid levels and completed data. A linear mixed model was conducted in Epigenome-wide association study (EWAS). Generalized estimating equation model was for gene expression analysis. We conducted Weighted correlation network analysis (WGCNA) to build co-methylated interconnected network. Additional Qingdao citizens were recruited for validation. Inference about Causation through Examination of Familial Confounding (ICE FALCON) was used to infer the possible direction of these relationships. A total of 476 top CpGs reached suggestively significant level (P < 10-4), of which, 192 CpGs were significantly associated with TG (FDR < 0.05). They were used to build interconnected network and highlight crucial genes from WGCNA. Finally, four CpGs in GATA4 were validated as risk factors for TC; six CpGs at ITFG2-AS1 were negatively associated with TG; two CpGs in PLXND1 played protective roles in HDL-C. ICE FALCON indicated abnormal TC was regarded as the consequence of DNA methylation in CpGs at GATA4, rather than vice versa. Four CpGs in ITFG2-AS1 were both causes and consequences of modified TG levels. Our results indicated that DNA methylation levels of 12 CpGs in GATA4, ITFG2-AS1, and PLXND1 were relevant to TC, TG, and HDL-C, respectively, which might provide new epigenetic insights into potential clinical treatment of dyslipidemia.

ABSTRACT

PURPOSE: We aimed to develop an artificial intelligence (AI) model based on transrectal ultrasonography (TRUS) images of biopsy needle tract (BNT) tissues for predicting prostate cancer (PCa) and to compare the PCa diagnostic performance of the radiologist model and clinical model.

METHODS: A total of 1696 2D prostate TRUS images were involved from 142 patients between July 2021 and May 2022. The ResNet50 network model was utilized to train classification models with different input methods: original image (Whole model), BNT (Needle model), and combined image [Feature Pyramid Networks (FPN) model]. The training set, validation set, and test set were randomly assigned, then randomized 5-fold cross-validation between the training set and validation set was performed. The diagnostic effectiveness of AI models and image combination was accessed by an independent testing set. Then, the optimal AI model and image combination were selected to compare the diagnostic efficacy with that of senior radiologists and the clinical model.

RESULTS: In the test set, the area under the curve, specificity, and sensitivity of the FPN model were 0.934, 0.966, and 0.829, respectively; the diagnostic efficacy was improved compared with the Whole and Needle models, with statistically significant differences (P < 0.05), and was better than that of senior radiologists (area under the curve: 0.667). The FPN model detected more PCa compared with senior physicians (82.9% vs. 55.8%), with a 61.3% decrease in the false-positive rate and a 23.2% increase in overall accuracy (0.887 vs. 0.655).

CONCLUSION: The proposed FPN model can offer a new method for prostate tissue classification, improve the diagnostic performance, and may be a helpful tool to guide prostate biopsy.

ABSTRACT

BACKGROUND: Distal hand ischemia syndrome (DHIS) is a well reported adverse outcome in patients with upper arm AV access. 25%-40% of these patients have been reported to be due to primary arterial disease complicated with significant arterial calcification. The effectiveness of revascularization of the distal arterial circulation on symptom resolution has not been reported yet.

METHODS: Retrospective single center analysis of patients evaluated for hand/forearm pain in patients with upper arm AV access who had arterial revascularization between 01/2016 and 12/2020 were included for the analysis. Fifty-one patients met inclusion criteria. Stenotic lesions greater than 70% in the subclavian, axillary, brachial, radial, or ulnar artery were treated with balloon angioplasty. Institutional approval was obtained to review charts.

OUTCOMES: Successful revascularization, improvement in pain in 48 h, 1 month, and 3 months.

RESULTS: Seventy six percent of patients had an upper arm Arteriovenous Fistula (AVF) and 24% patients had an upper arm Arteriovenous Graft (AVG). Mean access flow was 1210 (556) ml/min. 55% of patients had radial or ulnar arterial stenosis, 45% had brachial/axillary or subclavian artery stenosis. 45% patients had lesions in both radial and ulnar arteries, 88% of patients were successfully revascularized. 76% (18) of patients had improvement in symptoms within 48 h and 68% remained symptom free in 3 months. Mean DHIS stage was 3.1 before intervention and improved to 1.1 post intervention (p < 0.001). Patient satisfaction with their AV access improved from 34% to 72% (p < 0.01). Multiple regression analysis did not reveal statistically significant correlations between time on dialysis vintage and other chronic medical conditions on post procedure symptom improvement.

CONCLUSIONS: DHIS with occlusive arterial disease can be successfully revascularized to improve symptoms. Complete evaluation of the inflow arterial segment and optimal endovascular revascularization could decrease the need for access revision procedures or access abandonment.

ABSTRACT

Currently available anthropometric body composition prediction equations were often developed on small participant samples, included only several measured predictor variables, or were prepared using conventional statistical regression methods. Machine learning approaches are increasingly publicly available and have key advantages over statistical modeling methods when developing prediction algorithms on large datasets with multiple complex covariates. This study aimed to test the feasibility of predicting DXA-measured appendicular lean mass (ALM) with a neural network (NN) algorithm developed on a sample of 576 participants using 10 demographic (sex, age, 7 ethnic groupings) and 43 anthropometric dimensions generated with a 3D optical scanner. NN-predicted and measured ALM were highly correlated (n = 116; R², 0.95, p < 0.001, non-significant bias) with small mean, absolute, and root-mean square errors (X ± SD, -0.17 ± 1.64 kg and 1.28 ± 1.04 kg; 1.64). These observations demonstrate the application of NN body composition prediction algorithms to rapidly emerging large and complex digital anthropometric datasets. Clinical Trial Registration: NCT03637855, NCT05217524, NCT03771417, and NCT03706612.

ABSTRACT

OBJECTIVES: Agriculture entered the discussions about safety climates late, despite being one of the most hazardous industries. We recently developed a safety climate scale in Bordeaux vineyards, for which we provided good evidence of reliability and construct validity (Grimbuhler and Viel 2019). In this study, we aimed to establish the external validity of this safety climate scale with the help of an independent national sample of vineyard professionals.

POPULATION AND METHODS: We approached vineyard managers and operators during compulsory training and certification procedures for pesticide-related activities. Trainees giving informed consent for participation in the study were asked to complete a safety climate questionnaire at the start and end of a training session. In total, 406 vineyard managers or operators completed the questionnaire at the start of the study, 37 of whom declined to complete the questionnaire at the end of the training session, leaving 369 subjects available for pretraining/post-training comparisons. Statistical comparisons were based on t-tests and mixed models for repeated measures.

RESULTS: A mean safety climate score of 82.91 (SD: 9.06) was obtained in the initial survey in the Bordeaux region, whereas the safety climate score was estimated at 83.78 (SD 10.39) in this nationwide survey (P = 0.23). A significant increase was observed after the training course, for the safety climate score (7.5%, P < 10-15) and for each of its 7 dimensions (P < 10-4 or less), in both univariate and multivariate analyses. However, the magnitude of these increases varied with dimension, ranging from 2.4% for rules and best practices to 15.5% for communication and feedback.

CONCLUSIONS: External validity was demonstrated by transferability and sensitivity to intervention. This safety climate scale can now be considered to provide a good inference of the safety culture, with a meaning generalizable across vineyards.

ABSTRACT

BACKGROUND: Persons with achondroplasia develop early obesity, which is a comorbidity associated with other complications. Currently, there are no validated specific predictive equations to estimate resting energy expenditure in achondroplasia.

METHODS: We analyzed the influence of body composition on this parameter and determined whether predictive models used for children with standard height are adjusted to achondroplasia. In this cross-sectional study, we measured anthropometric parameters in children with achondroplasia. Fat mass was obtained using the Slaughter skinfold-thickness equation and resting energy expenditure was determined with a Fitmate-Cosmed calorimeter and with predictive models validated for children with average height (Schofield, Institute of Medicine, and Tverskaya).

RESULTS: All of the equations yielded a lower mean value than resting energy expenditure with indirect calorimetry (1256±200 kcal/day [mean±SD]) but the closest was the Tverskaya equation (1017 ± 64 kcal/day), although the difference remained statistically significant. We conclude that weight and height have the greatest influence on resting energy expenditure.

CONCLUSION: We recommend studying the relationship between body composition and energy expenditure in achondroplasia in more depth. In the absence of valid predictive models suitable for clinical use to estimate body composition and resting energy expenditure in achondroplasia, it is recommended to use the gold standard methods by taking into account certain anthropometric parameters.

ABSTRACT

PURPOSE: To evaluate tolerability, pathologic response, and disease outcomes utilizing pre-operative stereotactic body radiation therapy (SBRT) followed by consolidation chemotherapy (CHT) prior to orthotopic liver transplant (OLT) in unresectable cholangiocarcinoma (CCA).

METHODS: This was a retrospective chart review of patients treated on OLT protocol at a single tertiary center from 2012 to 2019. Patients received pre-operative SBRT (40-50 Gy in 5 fractions) followed by CHT until progression or OLT. Progression-free survival (PFS) and overall survival (OS) were compared via log-rank test and Cox proportional hazards regression.

RESULTS: 26 patients (84.6% hilar, 15.4% intrahepatic) were identified for analysis. Eight patients (30.8%) patients developed acute toxicity after SBRT, mostly grade 1 nausea. Nine (34.6%) patients underwent OLT of which 4 (44.4%) achieved a pathologic complete response (pCR). Five (55.6%) OLT patients, including 2 pCR, developed recurrence at a median time of 49.9 weeks after OLT. 3-year OS for the OLT and dropout cohort was 75% and 9%, respectively (p < 0.0001). OS in hilar tumors only was statistically different for those that achieved a pCR (p = 0.014).

CONCLUSIONS: Pre-operative SBRT is a well-tolerated and effective radiation technique as part of OLT protocol for unresectable CCA and conferred in a pCR rate of 44% within our cohort.
