OCT angiography in the monitoring of vaginal health

APL Bioeng. 2023 Nov 7;7(4):046112. doi: 10.1063/5.0153461. eCollection 2023 Dec.

ABSTRACT

Fractional-pixel CO2 laser therapy shows promise for treating the genitourinary syndrome of menopause (GSM). Nevertheless, it remains controversial in the field of female pelvic medicine. This is due to the inherent difficulties in obtaining noninvasive biopsies to evaluate the treatment’s efficacy and safety objectively. To address this challenge, we developed a noninvasive intravaginal optical coherence tomography (OCT)/OCT angiography (OCTA) endoscopic system, whose probe features a shape identical to the laser treatment probe. This system can provide high-resolution OCT images to identify the microstructure of vaginal tissue and visualize the vasculature network in vivo. We conducted clinical research on 25 post-menopausal patients with GSM. OCT/OCTA scans were acquired at four different locations of the vagina (distal anterior, distal posterior, proximal anterior, and proximal posterior) during the whole laser treatment session. A U-Net deep learning model was applied to segment the vaginal epithelium for assessing vaginal epithelial thickness (VET). Blood vessel density and VET were quantified to monitor the efficacy of fractional-pixel CO2 laser therapy. Statistical correlation analyses between these metrics and other clinical scores were conducted, validating the utility of our system. This OCT/OCTA endoscopic system has great potential to serve as a noninvasive biopsy tool in gynecological studies to screen, evaluate, and guide laser treatment for GSM.

Effect of T-regulatory cells and interleukin-35, interleukin-10, and transforming growth factor-beta on diffuse large B-cell lymphoma

World J Clin Cases. 2023 Oct 16;11(29):7075-7081. doi: 10.12998/wjcc.v11.i29.7075.

ABSTRACT

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin lymphoma that affects B lymphocytes. It can develop in the lymph nodes and can be localized or generalized. Despite DLBCL being considered potentially curable, little research has been conducted on the relationship between the body’s immune response and DLBCL.

AIM: To study the expression and significance of T-regulatory cells (Tregs) interleukin (IL)-35, IL-10, and transforming growth factor-beta (TGF-β) in DLBCL.

METHODS: Data from 82 patients with DLBCL who were initially admitted to The First Affiliated Hospital of Ningbo University (Zhejiang Province, China) between January 2017 and June 2022 and treated with standard first-line regimens were reviewed. Three patients were lost to follow-up; thus, 79 patients were included in the statistical analysis and then divided into three groups according to the evaluation of clinical efficacy: Incipient (new-onset and treatment-naïve), effectively treated, and relapsed-refractory. Thirty healthy individuals were included in the control group. The expression of peripheral blood T lymphocytes and their associated factors IL-35, IL-10, and TGF-β in the four groups were observed.

RESULTS: In contrast to the successfully treated and normal control groups, both the incipient and relapse-refractory groups exhibited greater proportions of CD4-positive (+) Tregs (P < 0.05), whereas the proportion of CD8+ Tregs did not differ substantially between the groups. Serum levels of IL-35 and IL-10 in the incipient and relapsed-refractory groups were higher than those in the effectively treated and normal control groups (P < 0.05). There was no statistically significant distinction in the expression level of TGF-β between the groups (P > 0.05). The correlation between IL-35 and IL-10 concentrations was significantly positive, with a correlation coefficient of 0.531 (P < 0.05). The correlation between IL-35 and TGF-β concentration was significantly positive, with a correlation coefficient of 0.375 (P < 0.05). The correlation between IL-10 and TGF-β concentration was significantly positive, with a correlation coefficient of 0.185 (P < 0.05). The expression concentrations of IL-35, IL-10 and TGF-β were apparently and positively correlated (P < 0.05).

CONCLUSION: Tregs IL-35, and IL-10 may be closely associated with the occurrence and development of DLBCL and the detection of related indices may be helpful in the analysis of disease prognosis.

Roles of biochemistry data, lifestyle, and inflammation in identifying abnormal renal function in old Chinese

World J Clin Cases. 2023 Oct 16;11(29):7004-7016. doi: 10.12998/wjcc.v11.i29.7004.

ABSTRACT

BACKGROUND: The incidence of chronic kidney disease (CKD) has dramatically increased in recent years, with significant impacts on patient mortality rates. Previous studies have identified multiple risk factors for CKD, but they mostly relied on the use of traditional statistical methods such as logistic regression and only focused on a few risk factors.

AIM: To determine factors that can be used to identify subjects with a low estimated glomerular filtration rate (L-eGFR < 60 mL/min per 1.73 m2) in a cohort of 1236 Chinese people aged over 65.

METHODS: Twenty risk factors were divided into three models. Model 1 consisted of demographic and biochemistry data. Model 2 added lifestyle data to Model 1, and Model 3 added inflammatory markers to Model 2. Five machine learning methods were used: Multivariate adaptive regression splines, eXtreme Gradient Boosting, stochastic gradient boosting, Light Gradient Boosting Machine, and Categorical Features + Gradient Boosting. Evaluation criteria included accuracy, sensitivity, specificity, area under the receiver operating characteristic curve (AUC), F-1 score, and balanced accuracy.

RESULTS: A trend of increasing AUC of each was observed from Model 1 to Model 3 and reached statistical significance. Model 3 selected uric acid as the most important risk factor, followed by age, hemoglobin (Hb), body mass index (BMI), sport hours, and systolic blood pressure (SBP).

CONCLUSION: Among all the risk factors including demographic, biochemistry, and lifestyle risk factors, along with inflammation markers, UA is the most important risk factor to identify L-eGFR, followed by age, Hb, BMI, sport hours, and SBP in a cohort of elderly Chinese people.

Meta-analysis on the effectiveness of parent education for children with disabilities

World J Clin Cases. 2023 Oct 16;11(29):7082-7090. doi: 10.12998/wjcc.v11.i29.7082.

ABSTRACT

BACKGROUND: Parents of children with disabilities often have difficulty understanding their child’s behavior and are unable to do it appropriately because they do not know what to do. The more we properly understand children with disabilities, the more positive the importance of parent education becomes in various aspects.

AIM: To demonstrate the effectiveness of parent education for children with disabilities in various aspects and present it as evidence that can be used clinically.

METHODS: For a meta-analysis on the effectiveness of parent education for children with disabilities, literature was collected from 2002 to 2022 using PubMed, Embase, Web of Science, Directory of Open Access Journals, and Europe PMC. Search terms were “disabled children,” “disabled children,” “parent education,” “parent training,” and “parent coaching.” The final searched literature included a total of 11 articles. To calculate the effect size, the mean, standard deviation, and sample size of the experimental and control groups were analyzed, and a meta-analysis was performed using RevMan version 5.4.1. To analyze statistical heterogeneity, a chi-square test was performed to evaluate the significance of Q statistics to indicate statistical heterogeneity.

RESULTS: The final literature totaled 11 articles, and a total of 4 items were analyzed. There were 5 studies on parental depression, the heterogeneity was 98%, and the effect size for parental depression was 0.35 [confidence interval (CI: 0.30-0.40)], indicating a small but statistically significant effect size. There were 4 studies on parenting attitude, the heterogeneity was 100%, the effect size on parenting attitude was 0.41 (CI: 0.37-0.46), which was a medium effect size, and the P value showed a statistically significant score. Additionally, face-to-face parent education was found to have a larger effect size than non-face-to-face education. Regarding parent education methods, face-to-face parent education had a medium effect size [0.57 (CI: 0.52-0.61]), while non-face-to-face parent education had a small effect size [0.23 (CI: 0.18-0.28]).

CONCLUSION: Parental education has shown high effectiveness in child development, and it has proven to be even more effective when face-to-face parenting education is conducted. Accordingly, more effective and objective data was presented. Based on this study, it is believed that parent education research applying various diagnostic groups should continue to be conducted.

Reference values of gait parameters in healthy Chinese university students: A cross-sectional observational study

World J Clin Cases. 2023 Oct 16;11(29):7061-7074. doi: 10.12998/wjcc.v11.i29.7061.

ABSTRACT

BACKGROUND: Gait is influenced by race, age, and diseases type. Reference values for gait are closely related to numerous health outcomes. To gain a comprehensive understanding of gait patterns, particularly in relation to race-related pathologies and disorders, it is crucial to establish reference values for gait in daily life considering sex and age. Therefore, our objective was to present sex and age-based reference values for gait in daily life, providing a valuable foundation for further research and clinical applications.

AIM: To establish reference values for lower extremity joint kinematics and kinetics during gait in asymptomatic adult women and men.

METHODS: Spatiotemporal, kinematics and kinetics parameters were measured in 171 healthy adults (70 males and 101 females) using the computer-aided soft tissue foot model. Full curve statistical parametric mapping was performed using independent and paired-samples t-tests.

RESULTS: Compared with females, males required more time (cycle time, double-limb support time, stance time, swing time, and stride time), and the differences were statistically significant. In addition, the step and stride lengths of males were longer. Compared to males, female cadence was faster, and statures-per-second and stride-per-minute were higher. There were no statistical differences in speed and stride width between the two groups. After adjusting for height, it was observed that women walked significantly faster than men, and they also had a higher cadence. However, in terms of step length, stride length, and stride width, both genders exhibited similarities.

CONCLUSION: We established reference values for gait speed and spatiotemporal gait parameters in Chinese university students. This contributes to a valuable database for gait assessment and evaluation of preventive or rehabilitative programs.

Meta-analysis of the efficacy and safety of daratumumab in the treatment of multiple myeloma

World J Clin Cases. 2023 Oct 16;11(29):7091-7100. doi: 10.12998/wjcc.v11.i29.7091.

ABSTRACT

BACKGROUND: The treatment of multiple myeloma has significantly progressed over the past half-century. The purpose of this study was to perform a systematic review and meta-analysis in order to explore the efficacy and safety of daratumumab in treating multiple myeloma.

AIM: To explore the efficacy and safety of daratumumab in treating multiple myeloma.

METHODS: A systematic literature search was performed using Chinese and English databases, including the China National Knowledge Infrastructure, Wanfang, China Biology Medicine, VIP, the Cochrane Library, Embase, and PubMed. The search encompassed studies in treating multiple myeloma with daratumumab, spanning from the inception of the database to June 2023. Revman 5.1 software was used for analysis.

RESULTS: Our analysis included eight English articles and one Chinese article of high quality. The meta-analysis results indicated that compared to other therapies, daratumumab could improve the overall response rate (ORR) [odds ratio (OR) = 2.67, 95% confidence interval (CI) = 2.01, 3.53, Z = 6.85, P < 0.00001], complete remission (CR) (OR = 2.87, 95%CI = 2.16, 3.83, Z = 7.23, P < 0.00001) and progression-free survival (PFS) time (hazard ratio = 0.48, 95%CI = 0.38,0.60, Z = 6.54, P < 0.00001) in patients with multiple myeloma. These differences were statistically significant. Additionally, these results suggested that daratumumab increases the risk of neutropenia and thrombocytopenia with minimal effect on the incidences of anemia and upper respiratory tract infections.

CONCLUSION: Daratumumab can improve ORR, CR rate, and PFS in patients with multiple myeloma. It also increases the risk of neutropenia and thrombocytopenia, necessitating careful monitoring during its clinical application.

Usefulness of analyzing endoscopic features in identifying the colorectal serrated sessile lesions with and without dysplasia

World J Clin Cases. 2023 Oct 16;11(29):6995-7003. doi: 10.12998/wjcc.v11.i29.6995.

ABSTRACT

BACKGROUND: Sessile serrated lesions (SSLs) are often missed on colonoscopy, and studies have shown this to be an essential cause of interstitial colorectal cancer. The SSLs with dysplasia (SSL-D+), in particular, have a faster rate of carcinogenesis than conventional tubular adenomas. Therefore, there is a clinical need for some endoscopic features with independent diagnostic value for SSL-D+s to assist endoscopists in making immediate diagnoses, thus improving the quality of endoscopic examination and treatment.

AIM: To compare the characteristics of SSLs, including those with and without dysplasia (SSL-D+ and SSL-D), based on white light and image-enhanced endoscopy, to achieve an immediate differential diagnosis for endoscopists.

METHODS: From January 2017 to February 2023, cases of colorectal SSLs confirmed by colonoscopy and histopathology at the Gastrointestinal Endoscopy Center of Beijing Tsinghua Changgung Hospital were collected. The general, endoscopic, and histopathological data were reviewed and analyzed to determine the diagnostic utility. Univariate analysis was used to find potential diagnostic factors, and then multivariate regression analysis was performed to derive endoscopic features with independent diagnostic values for the SSL-D+.

RESULTS: A total of 228 patients with 253 lesions were collected as a result. There were 225 cases of colorectal SSL-Ds and 28 cases of SSL-D+s. Compared to the colorectal SSL-D, the SSL-D+ was more common in the right colon (P = 0.027) with complex patterns of depression, nodule, and elevation based on cloud-like surfaces (P = 0.003), reddish (P < 0.001), microvascular varicose (P < 0.001), and mixed type (Pit II, II-O, IIIL, IV) of crypt opening based on Pit II-O (P < 0.001). Multifactorial logistic regression analysis indicated that lesions had a reddish color [odds ratio (OR) = 18.705, 95% confidence interval (CI): 3.684-94.974], microvascular varicose (OR = 6.768, 95%CI: 1.717-26.677), and mixed pattern of crypt opening (OR = 20.704, 95%CI: 2.955-145.086) as the independent predictors for SSL-D+s.

CONCLUSION: The endoscopic feature that has independent diagnostic value for SSL-D+ is a reddish color, microvascular varicose, and mixed pattern of crypt openings.

Associations between child abuse and neglect, and dento-alveolar injuries in a Children’s hospital population

Dent Traumatol. 2023 Nov 9. doi: 10.1111/edt.12902. Online ahead of print.

ABSTRACT

BACKGROUND/AIM: The purpose of this study was to identify social variables common to children with dento-alveolar trauma (DAT) and child abuse and neglect (CAN) in a large children’s hospital population.

METHODS: Emergency department data from an urban trauma Level 1 children’s hospital were queried between December 02, 2017 and September 30, 2022 to identify children with both DAT and CAN. Patients with DAT and CAN were compared to DAT-only children in a case-control study design. Descriptive statistics were used to report characteristics of children in case and control groups. Chi-Squared and Fisher’s exact tests were used to compare cases and controls. The level of significance was set at p ≤ .05.

RESULTS: In total, 14 children who had DAT and CAN reported simultaneously comprised the case group. A total of 42 children with DAT-only, age/sex matched with cases, comprised the control group. Mean (SD) age of cases was 10.4 (±4) and controls was 10.1 (±3.9) years-old. Eight cases (57.1%) and 24 controls (57.1%) were female. No statistical differences (p = .05) were present for language, race, insurance coverage, parental custody, legal guardianship, and type of residence for cases versus controls. Five (35.7%) cases had a special need versus 4 (9.5%) controls and was statistically different (p = .03). Nine (64.3%) cases had behavioral problems versus 13 (31%) controls (p = .05). Cases were more likely to have facial injuries than controls (74.3 vs. 31%), however no significant differences were present for total number of injured teeth, head injury or neck injury between cases and controls. In half of cases, the perpetrator reported was the sibling.

CONCLUSIONS: Demographics did not predict CAN in children with dental injuries. Sibling violence should be considered in suspected CAN children.

Validation of the European SCORE2 Models in a Canadian Primary Care Cohort

Eur J Prev Cardiol. 2023 Nov 8:zwad352. doi: 10.1093/eurjpc/zwad352. Online ahead of print.

ABSTRACT

INTRODUCTION: SCORE2 was recently developed to predict atherosclerotic cardiovascular disease (ASCVD) in Europe. Whether these models could be used outside of Europe is not known. The objective of this study was to test the validity of SCORE2 in a large Canadian cohort.

METHODS: A primary care cohort of persons with routinely collected electronic medical record data from January 1, 2010, to December 31, 2014, in Ontario, Canada was used for validation. The SCORE2 models for younger persons (YP) were applied to 57,409 individuals aged 40 to 69 while the models for older persons (OP) were applied to 9,885 individuals 70 to 89 years of age. Five-year ASCVD predictions from both the uncalibrated and low-risk region recalibrated SCORE2 models were evaluated.

RESULTS: The C-statistic for SCORE2-YP was 0.74 in women and 0.69 in men. The uncalibrated SCORE2-YP overestimated risk by 17% in women and underestimated by 2% in men. In contrast, the low-risk region recalibrated model demonstrated worse calibration, overestimating risk by 100% in women and 36% in men. The C-statistic for SCORE2-OP was 0.64 and 0.62 in older women and men, respectively. The uncalibrated SCORE2-OP overestimated risk by more than 100% in both sexes. The low-risk region recalibrated model demonstrated improved calibration, but still overestimated risk by 60% in women and 13% in men.

CONCLUSIONS: The performance of SCORE2 to predict ASCVD risk in Canada varied by age group and depended on whether regional calibration was applied. This underscores the necessity for validation assessment of SCORE2 prior to implementation in new jurisdictions.

The effect of resistance training on PCSK9 levels in patients undergoing cardiac rehabilitation after coronary artery bypass grafting: a randomized study

BMC Cardiovasc Disord. 2023 Nov 9;23(1):549. doi: 10.1186/s12872-023-03571-7.

ABSTRACT

BACKGROUND: Resistance training is commonly recommended as part of secondary prevention for post-coronary artery bypass graft (CABG) patients in conjunction with aerobic exercise. Despite its potential benefits, there is currently a lack of studies investigating the impact of resistance training on proprotein convertase subtilisin kexin 9 (PCSK9).

AIM: To evaluate the effect of intensive resistance training on proprotein convertase subtilisin kexin 9 (PCSK9) levels among post-CABG patients undergoing cardiac rehabilitation (CR).

METHODS: In this prospective, open-label, randomized trial, 87 post-coronary artery bypass graft (CABG) patients were randomly assigned into two groups: moderate to high intensity resistance training and aerobic training (n = 44) or aerobic training alone (n = 43) for a total of 12 sessions. Changes in PCSK9 levels was determined as a primary endpoint, while secondary endpoints included changes in the six-minute walk test (6-MWT) results, aerobic capacity, WHO-5 well-being index, fasting blood glucose, and lipid profile. Both groups underwent intention-to-treat analysis.

RESULTS: Following completion of cardiac rehabilitation program, the intervention group demonstrated a significant decrease in mean PCSK9 levels when compared to the control group (β = -55 ng/ml, 95% CI -6.7 to -103.3, p = 0.026), as well as significant improvements in the 6-MWT result (β = 28.2 m, 95% CI 2.4-53.9, p = 0.033), aerobic capacity (β = 0.9 Mets, 95% CI 0.1-1.7, p = 0.021), and WHO-5 well-being index (β = 8.1, 95% CI 2.0-14.4, p = 0.011) in patients who received resistance and aerobic training. No statistically significant changes were observed in fasting blood glucose, cholesterol, LDL-C, HDL-C, and triglyceride levels.

CONCLUSION: Resistance training in CR significantly reduced PCSK-9 levels and increases patient’s functional capacity and quality of life. (NCT02674659 04/02/2016).
