Differences in the Fat Attenuation Index Ratio of Pericoronary Adipose Tissue And Aortic Root Epicardial Adipose Tissue in Various Plaques.

BACKGROUND: The fat attenuation index (FAI) of pericoronary adipose tissue is associated with coronary inflammatory reactions. OBJECTIVE: This study aimed to analyze the difference in the FAI ratio between pericoronary adipose tissue volume and aortic root epicardial adipose tissue volume (AO-EATV) using computed tomography (CT) in various plaques. METHOD: In total, 645 coronary artery CT angiogram images from 215 patients were collected. The types and number of coronary plaques were recorded, and the plaque volume and pericoronary FAI of each branch were compared between the groups. The ratio of the FAI in branches with or without plaques to the AO-EATV was determined and statistically analyzed between the groups. RESULTS: No significant difference in the plaque volume among the left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) (P > 0.05) as well as in the FAI was observed among various plaque groups (P > 0.05). FAI[LAD]/AO-EATV was in the following order: noncalcified plaques (0.70 ± 0.06) < mixed plaques (0.72 ± 0.06) < calcified plaques (0.73 ± 0.08) < no plaques (0.74 ± 0.07); FAI[LCX]/AOEATV was in the following order: noncalcified plaques (0.71 ± 0.06) < mixed plaques (0.72 ± 0.08) < calcified plaques (0.73 ± 0.09) < no plaques (0.74 ± 0.06); and FAI[RCA]/AO-EATV was in the following order: noncalcified plaques (0.71 ± 0.06) < mixed plaques (0.73 ± 0.07) < calcified plaques (0.74 ± 0.07) < no plaques (0.75 ± 0.09); the differences were statistically significant in each group (P = 0.041, 0.043, and 0.028, respectively). CONCLUSION: Compared to simply comparing FAI, FAI/AO-EATV varied in the coronary arteries in various plaque groups. FAI/AO-EATV was lower in noncalcified or mixed plaques and was associated with coronary inflammatory reactions.

Meta-analysis of Huangqi (Astragalus membranaceus) and Chinese Yam (Rhizoma Dioscoreae) for Diabetic Nephropathy.

Context: Diabetic nephropathy (DN), also known as diabetic kidney disease (DKD), has caused enormous economic pressure and serious health problems worldwide. TCM practitioners commonly use a combination of Astragalus membranaceus (A. membranaceus) and Rhizoma Dioscoreae (R. Dioscoreae) in the treatment of DN. Research is still lacking on the therapeutic effects of TCM for DN. Objective: The systematic review and meta-analysis intended to evaluate whether the combination of A. membranaceus and R. Dioscoreae together with Western medicine can provide better efficacy against DN than treatment with traditional Western medicine alone, to provide a clinical medical basis for the use of the TCM combination. Design: The research team performed a performed a systematic narrative review by searching the Web of Science, Science Direct, Pubmed, China National Knowledge Infrastructure (CNKI), VIP, Wanfang, Chinese Science and Technology Journal Database, and Biomedical Literature Chinese Database from databases' inceptions to May 2023. The team used the keywords astragalus and yam, diabetic nephropathy, antidiabetic, and 24-h urinary protein. Setting: The review and meta-analysis occurred at Jiangxi Hospital of Integrated Traditional China and Western Medicine in Nanchang, Jiangxi, China. Intervention: To perform a subgroup analysis, the research team divided the studies into two groups based on the TCM treatment course, with one subgroup receiving treatment for ≤4 weeks and the second receiving treatment for >4 weeks, to judge whether a time-dependence existed for the effects of the TCM combination on UP. Outcome Measure: All studies used 24-h urinary protein (UP) as the outcome measure. Results: In all studies, all heterogeneous (P < .01, I2 = 94%, the intervention groups had a significantly greater reduction in 24-h UP than the control groups did (P < .05). The heterogeneity for a treatment course of ≤4 weeks was P < .01, I2 = 97%, and for a course of >4 weeks was P < .01, I2 = 87%. For both ≤4 weeks and >4 weeks, the intervention groups had a significantly greater reduction in 24-h UP than the control groups did, with P < .01 and P < .01, respectively. The protein effect wasn't time dependent. Conclusions: A. membranaceus and R. Dioscoreae can significantly reduce UP production, and inhibition of UP wasn't time-dependent.

Combinations of Digital Breast Tomosynthesis and Full-field Digital Mammography for Different Density Types of Breasts.

BACKGROUND: The combination of FFDM and DBT can significantly improve the diagnostic efficiency of breast cancer, but with the increase of breast radiation absorbed dose. OBJECTIVES: To compare and analyze the radiation dose and diagnostic performance of different mammography positions combinations of digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) for different density types of breasts. METHODS: This retrospective study involved 1,195 patients who underwent simultaneous breast DBT and FFDM. The mammography combinations were Group A, FFDM(CC+MLO); Group B, FDM(CC)+DBT(MLO); Group C, FFDM(MLO)+DBT(CC); Group D, DBT(CC+MLO); and Group E, FFDM(CC+MLO)+DBT(CC+MLO). An intergroup comparative analysis of radiation dose and diagnostic performance of different combinations of mammography positions for different breast density types was performed using the pathologic and 24-month follow-up results as the diagnostic basis. RESULTS: Overall, 2,403 mammograms indicated 477 cases of non-dense breast tissues and 1,926 cases of dense breast tissues. Differences in the mean radiation dose for each non-dense and dense breast group were statistically significant. The areas under the diagnostic receiver operating characteristic (ROC) curves for the non-dense breast group were not statistically significant. In the dense breast group, the z-values were 1.623 (p = 0.105) and 1.724 (p = 0.085) for the area under the ROC curve in Group C compared with Groups D and E, respectively, and 0.724 (p = 0.469) when comparing Group D with Group E. The differences between the remaining groups were statistically significant. CONCLUSION: Group A had the lowest radiation dose and no significant difference in diagnostic performance compared with the other non-dense breast groups. Group C had high diagnostic performance in the dense breast group considering the low radiation dose.

The efficacy of telemedicine for pain management in patients with cancer: a systematic review and meta-analysis.

Background: Pain is the most common cancer-related symptom, but it is often undertreated. Telemedicine is widely used in cancer treatment, but its effectiveness is uncertain. Objective: We aimed to evaluate the impact of telemedicine intervention on pain in patients with cancer. Design: Methodological quality and risk-of-bias evaluation were conducted, and the sources of heterogeneity were explored through subgroup analysis and sensitivity analysis. Data Sources and Methods: PubMed, Embase, Web of Science, Cochrane Library, and clinical trial databases were searched up to 16 August 2022. Randomized controlled trials of the impact of telemedicine intervention regarding pain in patients with cancer were included, and the results related to pain were extracted. Results: Twenty-one randomized controlled trials were selected from 1810 articles. A total of 1454 patients received telemedicine interventions, and 2213 received conventional medical services. Telemedical intervention had a positive effect on improving pain intensity [standard mean deviation (SMD) = -0.28, 95% confidence interval (CI): -0.49 to -0.06, p = 0.01] and pain interference (SMD = -0.41, 95% CI: -0.54 to -0.28, p < 0.00001), with statistical difference between the two groups. The subgroup analysis results showed that the telemedicine subgroup based on an application (SMD = -0.54, 95% CI: -0.91 to -0.18, p = 0.004) and the subgroup with intervention time ⩾ 6 months (SMD = -0.33, 95% CI: -0.52 to -0.13, p = 0.001), both demonstrated significant improvement regarding pain intensity, with significant statistical difference between the two groups. When the follow-up time was ⩾ 6 months, there was no significant difference (SMD = -0.24, 95% CI: -0.55 to 0.07, p = 0.13). Conclusion: Compared with conventional medical services, telemedicine intervention can improve the pain of patients with cancer and is effective and acceptable regarding symptom monitoring. Integrating telemedicine interventions into cancer pain management may be a feasible option. But its long-term effects still need to be confirmed with more high-quality randomized controlled trials in the future. Registration: https://www.crd.york.ac.uk/PROSPERO/; CRD42022361990.

Chest computed tomography findings of the Omicron variants of SARS-CoV-2 with different cycle threshold values.

BACKGROUND: The Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mainly infects the upper respiratory tract. This study aimed to determine whether the probability of pulmonary infection and the cycle threshold (Ct) measured using the fluorescent polymerase chain reaction (PCR) method were related to pulmonary infections diagnosed via computed tomography (CT). AIM: To analyze the chest CT signs of SARS-CoV-2 Omicron variant infections with different Ct values, as determined via PCR. METHODS: The chest CT images and PCR Ct values of 331 patients with SARS-CoV-2 Omicron variant infections were retrospectively collected and categorized into low (< 25), medium (25.00-34.99), and high (≥ 35) Ct groups. The characteristics of chest CT images in each group were statistically analyzed. RESULTS: The PCR Ct values ranged from 13.36 to 39.81, with 99 patients in the low, 155 in the medium, and 77 in the high Ct groups. Six abnormal chest CT signs were detected, namely, focal infection, patchy consolidation shadows, patchy ground-glass shadows, mixed consolidation ground-glass shadows, subpleural interstitial changes, and pleural changes. Focal infections were less frequent in the low Ct group than in the medium and high Ct groups; these infections were the most common sign in the medium and high Ct groups. Patchy consolidation shadows and pleural changes were more frequent in the low Ct group than in the other two groups. The number of patients with two or more signs was greater in the low Ct group than in the medium and high Ct groups. CONCLUSION: The chest CT signs of patients with pulmonary infection caused by the Omicron variants of SARS-CoV-2 varied depending on the Ct values. Identification of the characteristics of Omicron variant infection can help subsequent planning of clinical treatment.

[Modified eProtocol-insulin for critically ill patients and application software].

Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.
