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-D^–s 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.

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.

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.

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).

ABSTRACT

BACKGROUND: Emergency contraceptives (EC) are used to avoid unintended pregnancy, hence avoiding its incidence and its effects. In Ethiopia, emergency contraception is commonly accessible, especially in the big cities. However, there is virtually little understanding of or awareness of EC and Ethiopia has a high abortion rate. Therefore this study was aimed to assess the magnitude and associated factors for emergency contraceptive knowledge in Ethiopia.

METHODS: The study was based on secondary data analysis of the Ethiopian Demographic and Health Survey 2016 data. A total weighted sample of 1236 reproductive age women was included. A multilevel mixed-effect binary logistic regression model was fitted to identify the significant associated factors of emergency contraceptive knowledge. Statistical significance was determined using Adjusted Odds Ratio (AOR) with 95% confidence interval.

RESULTS: Overall magnitude of emergency contraceptive knowledge was observed to be 17.19% (95% CI: 15.18, 19.40) with intra-class correlation (ICC) 57% and median odds ratio (MOR) 6.4 in the null model. Women’s age 25-34 (AOR = 2.6; 95% CI: 1.2, 5.5), and 35-49 (AOR = 1.5; 95% CI: 1.06, 3.3), secondary and above educational level (AOR = 3.41; 95% CI: 2.19, 4.88), media exposure (AOR = 2.97; 95% CI: 1.56, 5.64), Being in metropolitan region (AOR = 2.68; 95% CI: 1.46, 4.74), and women being in urban area (AOR = 3.19; 95% CI: 1.20, 5.23) were associated with emergency contraceptive knowledge.

CONCLUSION: Emergency contraceptive knowledge in this study was low. Women age, educational level, media exposure, residency, and region were significantly associated with emergency contraceptive knowledge. Therefore, to enhance understanding and use of ECs in the current Ethiopian setting, it is imperative to ensure exposure to EC information, particularly in rural regions.

ABSTRACT

BACKGROUND: Clinical evidence suggests that pregnant women are more vulnerable to COVID-19, since they are at increased risk for disease progression and for obstetric complications, such as premature labor, miscarriage, preeclampsia, cesarean delivery, fetal growth restriction and perinatal death. Despite this evidence, pregnant women are often excluded from clinical trials, resulting in limited knowledge on COVID-19 management. The aim of this systematic review and meta-analysis is to provide better evidence on the efficacy and safety of available COVID-19 treatment in pregnant women.

METHODS: Four authors searched major electronic databases from inception until 1 st November-2022 for controlled trials/observational studies, investigating outcomes after the administration of anti-SARS-CoV-2 treatments in pregnant women affected by COVID-19. The analyses investigated the cumulative incidence of delivery and maternal outcomes in pregnant women, comparing those taking active medication vs standard care. Risk ratios (RRs) with 95% confidence intervals were calculated. Statistical significance was assessed using the random effects model and inverse-variance method. This systematic review and meta-analysis was conducted in accordance with the updated 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The protocol has been registered in Prospero (number registration: CRD42023397445).

RESULTS: From initially 937 non duplicate records, we assessed the full texts of 40 articles, finally including ten studies. In six studies, including 1627 patients, the use of casirivimab/imdevimab (CAS/IMD), remdesivir, and IFN-alpha 2b significantly decreased the need of cesarean section ((RR = 0.665; 95%CI: 0.491-0.899; p = 0.008; I 2 = 19.5%;) (Table 1, (Fig. 1). Treatments did not decrease the risk of preterm delivery, admission to neonatal ICU, or stillbirth/perinatal loss (p-values > 0.50 for all these outcomes) and did not prevent the progression of disease towards severe degrees (k = 8; 2,374 pregnant women; RR = 0.778; 95%CI: 0.550-1.099; p = 0.15; I 2 = 0%). Moreover, the use of medications during pregnancy did not modify the incidence of maternal death in two studies (Table 2).

CONCLUSIONS: To our analysis, CAS/IMD, remdesivir, and IFN alpha 2b reduced the number of cesarean sections but demonstrated no effect on disease progression and other obstetric and COVID-19 related outcomes. The inability to evaluate the influence of viral load on illness development in pregnant women was attributed to lack of data. In our systematic review, no major side effects were reported. Though, it is essential for the medical community to focus more on clinical trials and less on episodic case reports and case series, with standardization of fetal and maternal outcomes.

ABSTRACT

BACKGROUND: Patients presenting to the emergency department with community-acquired pneumonia (CAP) are characterized by advanced age, comorbidities, critical illness and less-than-typical symptoms, posing a diagnostic challenge. Plasma heparin-binding protein (HBP) and the heparin-binding protein-to-albumin ratio (HBP/Alb) have not been adequately studied in the early diagnosis of CAP. This study assessed the diagnostic value of plasma HBP, HBP/Alb, and conventional inflammatory markers in emergency department patients with CAP.

METHODS: We enrolled 103 patients with CAP, retrospectively analyzed the patients’ clinical data, and divided the CAP patients into antibiotic (n = 79) and non-antibiotic (n = 24) groups based on whether antibiotics were administered prior to blood sampling and laboratory tests. The control group was comprised of 52 non-infected patients admitted during the same period. Within 24 h of admission, plasma HBP, serum procalcitonin (PCT), white blood cell count (WBC), neutrophil-to-lymphocyte ratio (NLR) and HBP/Alb levels were collected separately and compared. The receiver operating characteristic (ROC) curve was plotted to assess the diagnostic value of each indicator for CAP patients. Utilizing the Kappa test, the consistency of each indicator used to evaluate CAP and clinical diagnosis was analyzed. Spearman correlation was used to analyze the correlation between plasma HBP and clinical indicators of CAP patients.

RESULTS: Plasma HBP, serum PCT, WBC, NLR and HBP/Alb were all elevated in the CAP group in comparison to the control group (P < 0.001). Plasma HBP, serum PCT, WBC, NLR and HBP/Alb levels did not differ statistically between antibiotic and non-antibiotic groups (P > 0.05). Plasma HBP and HBP/Alb had the highest diagnostic accuracy for CAP, the area under the ROC curve (AUC) were 0.931 and 0.938 (P < 0.0001), and the best cut-off values were 35.40 ng/mL and 0.87, respectively. In evaluating the consistency between CAP and clinical diagnosis, the Kappa values for HBP, PCT, WBC, NLR and HBP/Alb were 0.749, 0.465, 0.439, 0.566 and 0.773, respectively. Spearman correlation analysis showed that plasma HBP was positively correlated with serum PCT, WBC, NLR and HBP/Alb in CAP patients (P < 0.001).

CONCLUSIONS: Plasma HBP and HBP/Alb have a high clinical diagnostic value for CAP and can be used as good and reliable novel inflammatory markers in the emergency department for the early diagnosis of CAP patients.

ABSTRACT

Research has demonstrated erosion of empathy in students during medical education. Particularly, U.S. studies have demonstrated empathy declines during clinical training in the third and fourth year of traditional medical programs. Yet, studies conducted outside the U.S. have not confirmed this trend. Timing and extent of patient interactions have been identified as empathy-protective factors. The need to examine empathy within different learning contexts has been noted, as has the need for longitudinal and time-series research designs to analyze trajectories. Between fall 2010 and spring 2019, we assessed empathy longitudinally among six student cohorts (N = 493) at a U.S. medical school, where patient interaction occurs early and throughout an integrated curriculum. Empathy levels of students in each cohort were assessed at five time points utilizing the Jefferson Scale of Physician Empathy-Student version. We hypothesized empathy levels will not degrade by program end, and trajectories will not show patterns of decline in Years Three and Four. Analysis of Variance (ANOVA) and Linear Mixed Model (LMM) analyses were used to analyze differences at baseline and changes in empathy trajectories. ANOVA analyses revealed statistically significant differences at baseline by class cohort (F(5, 487) = [23.28], p < 0.001). LMM analyses indicated empathy was either significantly higher or not different at the end of the program (F(19, 1676) = [13.97], p < 0.001). Empathy trajectories varied among cohorts; yet, none resulted in an overall empathy decline by the end of the program. Findings demonstrate empathy in U.S. medical students can be unchanged or higher by the end of medical education. Outcomes are consistent with reports of non-declining medical student empathy outside the U.S. and support the notion of context-specificity. Results further support recent research, suggesting decreases in empathy during training can stabilize or increase by program end. These findings have important implications for future empathy research context and design considerations, as well as program planning.

ABSTRACT

PURPOSE: Joint line (JL) position change in total knee arthroplasty (TKA) may alter knee biomechanics and impact function. The purpose of this study was to compare the change in JL position between robotic-assisted TKA (RA-TKA) and conventional TKA (C-TKA).

METHODS: A retrospective, radiographic analysis was conducted of patients who underwent RA-TKA and C-TKA to compare JL position change. JL position was measured in consecutive RA-TKAs and C-TKAs performed by four fellowship-trained arthroplasty surgeons. Statistical analysis was done utilizing t-tests and Mann Whitney U tests, with statistical significance being defined as a p value < 0.05.

RESULTS: Six hundred total RA-TKAs and 400 total C-TKAs were included in the analysis. There were no significant differences in patient baseline characteristics such as body mass index, range of motion, and tibiofemoral coronal alignment. RA-TKAs were associated with an average of 0.04 (2.2) mm JL position change, and C-TKAs were associated with an average 0.5 (3.2) mm JL position change (p = 0.030). There were inter-surgeon differences when comparing the change in JL position for RA-TKAs and C-TKAs between the four participating surgeons.

CONCLUSION: RA-TKA leads to better preservation of the JL position than C-TKA, and this seems to be dependent on the arthroplasty surgeon’s preferences and techniques during TKA. Whether this statistically significant difference is clinically relevant needs to be further investigated.

ABSTRACT

Tissues within an organism and even cell types within a tissue can age with different velocities. However, it is unclear whether cells of one type experience different aging trajectories within a tissue depending on their spatial location. Here, we used spatial transcriptomics in combination with single-cell ATAC-seq and RNA-seq, lipidomics and functional assays to address how cells in the male murine liver are affected by age-related changes in the microenvironment. Integration of the datasets revealed zonation-specific and age-related changes in metabolic states, the epigenome and transcriptome. The epigenome changed in a zonation-dependent manner and functionally, periportal hepatocytes were characterized by decreased mitochondrial fitness, whereas pericentral hepatocytes accumulated large lipid droplets. Together, we provide evidence that changing microenvironments within a tissue exert strong influences on their resident cells that can shape epigenetic, metabolic and phenotypic outputs.
