ABSTRACT

This study aims at exploring the relationships between adverse childhood experience (ACEs) and parental burnout. A total of 583 postnatal Chinese mothers were recruited in this cross-sectional study. Maternal ACEs were measured by Adverse Childhood Experience Questionnaire-Revised and parental burnout was measured by Parental Burnout Assessment. Multiple linear and binary logistic regression, and latent class analysis were used to explore the association between each type and cumulative ACEs and parental burnout. We found ACEs were associated with a higher risk of parental burnout. However, the association differed in the type of ACEs. The higher levels of physical abuse (B = 0.971 ~ 0.459, all p < 0.05) and emotional neglect (B = 1.010 ~ 1.407, all p < 0.05) in childhood were correlated with more serious parental burnout. The higher levels of self-threatened (B = 0.429 ~ 0.559, all p < 0.05) and self-deprived experience (B = 0.384 ~ 0.462, all p < 0.05), higher number of ACEs type (B = 2.909 ~ 3.918, all p < 0.05) were associated with more serious parental burnout. Results were consistent after combining four dimensions of parental burnout as a whole in LCA. This study indicated that maternal ACEs were associated with parental burnout. Women with self-deprived, self-threatened and more types of ACEs should be paid special attention.

ABSTRACT

INTRODUCTION/OBJECTIVES: Social determinants of health (SDoH) screening and intervention in pediatric primary care depends upon caregiver disclosure of adverse household or social conditions and thus may be influenced by perceived bias or stigma. This paper examines to what extent parents’ experience of their child’s medical home is associated with their perceptions of a practice-based social needs intervention.

METHODS: We conducted a cohort study of data reported by 73 parents of children obtaining care in a medical home with an embedded SDoH navigation program. Using survey data collected in October 2021 and October 2022, we calculated descriptive statistics and non-parametric bivariate analyses of the association between engagement with the SDoH navigation program and parent-reported social needs, stress, and perception of care quality as measured by the Person-Centered Primary Care Measure (PCPCM).

RESULTS: Initial ratings of care quality were high (mean baseline PCPCM score = 3.63) and remained high on second interview (mean change in PCPCM score = -0.04, 95%CI -0.16, 0.09, P = .58) despite significant reductions in parents’ ratings of access to care over time. Parents reported substantial stress, unmet social needs, and unmet healthcare needs, with 41 families (56%) ever using the practice-based SDoH program, including 16 (22%) who were new users in 2022. There was no association observed between PCPCM score and parent stress, unmet social needs, or use of SDoH services.

CONCLUSIONS: Parents’ perceptions of care delivered in their child’s medical home appears to be stable on repeat measurement, and independent of family context or interactions with social needs navigation services offered in the practice.

ABSTRACT

PURPOSE: To assess the efficacy of machine learning and radiomics analysis by computed tomography (CT) in presurgical setting, to predict RAS mutational status in colorectal liver metastases.

METHODS: Patient selection in a retrospective study was carried out from January 2018 to May 2021 considering the following inclusion criteria: patients subjected to surgical resection for liver metastases; proven pathological liver metastases; patients subjected to enhanced CT examination in the presurgical setting with a good quality of images; and RAS assessment as standard reference. A total of 851 radiomics features were extracted using the PyRadiomics Python package from the Slicer 3D image computing platform after slice-by-slice segmentation on CT portal phase by two expert radiologists of each individual liver metastasis performed first independently by the individual reader and then in consensus. Balancing technique was performed, and inter- and intraclass correlation coefficients were calculated to assess the between-observer and within-observer reproducibility of features. Receiver operating characteristics (ROC) analysis with the calculation of area under the ROC curve (AUC), sensitivity (SENS), specificity (SPEC), positive predictive value (PPV), negative predictive value (NPV) and accuracy (ACC) were assessed for each parameter. Linear and non-logistic regression model (LRM and NLRM) and different machine learning-based classifiers were considered. Moreover, features selection was performed before and after a normalized procedure using two different methods (3-sigma and z-score).

RESULTS: Seventy-seven liver metastases in 28 patients with a mean age of 60 years (range 40-80 years) were analyzed. The best predictors, at univariate analysis for both normalized procedures, were original_shape_Maximum2DDiameter and wavelet_HLL_glcm_InverseVariance that reached an accuracy of 80%, an AUC ≥ 0.75, a sensitivity ≥ 80% and a specificity ≥ 70% (p value < < 0.01). However, a multivariate analysis significantly increased the accuracy in RAS prediction when a linear regression model (LRM) was used. The best performance was obtained using a LRM combining linearly 12 robust features after a z-score normalization procedure: AUC of 0.953, accuracy 98%, sensitivity 96%, specificity of 100%, PPV 100% and NPV 96% (p value < < 0.01). No statistically significant increase was obtained considering the tested machine learning both without normalization and with normalization methods.

CONCLUSIONS: Normalized approach in CT radiomics analysis allows to predict RAS mutational status in colorectal liver metastases patients.

ABSTRACT

OBJECTIVES: To identify the prevalence and frequency of physiotherapy, chiropractic, and/or osteopathy care in Australians with workers’ compensation claims for low back pain (LBP).

METHODS: We included workers with accepted workers’ compensation claims longer than 2 weeks from the Australian states of Victoria, Queensland, South Australia, and Western Australia. Workers were grouped by whether they attended physiotherapy, chiropractic, and/or osteopathy in the first 2 years of their claim. Descriptive statistics and logistic regression were used to describe differences between groups. Descriptive statistics and negative binomial regression were used to describe differences in the number of attendances in each group.

RESULTS: Most workers had at least one physical therapy attendance during the period of their claim (n = 23,619, 82.0%). Worker state, socioeconomic status, and remoteness were the largest contributing factors to likelihood of physical therapy attendance. Most workers only attended physiotherapy (n = 21,035, 89.1%, median of 13 times). Far fewer only attended chiropractic (n = 528, 2.2%, median of 8 times) or only osteopathy (n = 296, 1.3%, median of 10 times), while 1,750 (7.5%) attended for care with more than one type of physical therapy (median of 31 times).

CONCLUSION: Most Australian workers with workers’ compensation time loss claims for LBP attend physiotherapy at least once during their claims. State of claim is the strongest predictor of which physical therapy profession they attend, possibly due to regional availability. Workers who see a physiotherapist have significantly more attendances. Future research should explore the relationship between these patterns of care and claimant outcomes, including work disability duration.

ABSTRACT

A systemic inflammatory response occurs during SARS-CoV2 infection and is associated with hypercoagulability and thrombotic events. From March 2020 in our hospital different dosages of low-molecular weight heparin (LMWH) were introduced according to the level of patient care intensity. Because bleeding episodes occurred in hospitalized COVID-19 patients on heparin, the dosage of LMWH at the end of first wave was tailored on the severity of COVID-19. The aim of this study is to describe bleeding and thrombotic events in patients hospitalized with SARS-CoV2 infection on LMWH therapy in the two waves of COVID-19 and analyze the factors associated with these events. Among 1143 patients enrolled in the COVID-19 Network registry, 912 were included in the analysis, 537 of them admitted during the first wave and 375 during the second. Bleeding events were 30 (3.3%): 22 (2.4%) major and 8 (0.9%) non-major. Arterial and venous thrombotic events were 6 (0.7%) and 24 (2.6%). The incidence of venous thrombotic events was higher in the first than in the second wave (0.29% [95% CI 0.20-0.45] events/day vs. 0.05% [95% CI 0.02-0.16]), with a 71% risk reduction (95% CI 22%-94%). The incidence of bleeding was 0.33% (95% CI 0.22-0.50) vs 0.14% events/day (95% CI 0.07-0.28), with no statistical between-wave difference (HR 0.41 95% CI 0.16-1.08). After adjusting for the competing risks of death and comorbidities, patients in the second wave had lower odds to have thrombotic events than in the first wave (0.24 HR [95% C.I. 0.07-0.89]). In this retrospective study on COVID-19 we found a low rate of hemorrhagic and thrombotic events, that may be explained by the absence in the case material of patients admitted to intensive care unit.

ABSTRACT

OBJECTIVES: White spot lesions are the most common iatrogenic effect observed during orthodontic treatment. This study aimed to compare the surface characteristics and antibacterial action of uncoated and coated orthodontic brackets.

MATERIALS AND METHODS: Sixty commercially available stainless steel brackets were coated with TiO₂ nanotubes and methacryloyloxyethylphosphorylcholine. The sample was divided into Group 1: uncoated orthodontic brackets, Group 2: Stainless steel brackets with TiO₂ nanotubes coating, Group 3: Stainless steel brackets with methacryloyloxyethylphosphorylcholine coating, and Group 4: Stainless steel brackets with TiO₂ nanotubes combined with methacryloyloxyethylphosphorylcholine coating. Surface characterization was assessed using atomic force microscopy and scanning electron microscopy. Streptococcus mutans was selected to test the antibacterial ability of the orthodontic brackets, total bacterial adhesion and bacterial viability were assessed. The brackets were subjected to scanning electron microscopy to detect the presence of biofilm.

RESULTS: The surface roughness was the greatest in Group 1 and least in Group 2 followed by Group 4 and Group 3 coated brackets. The optical density values were highest in Group 1 and lowest in Group 4. Comparison of colony counts revealed high counts in Group 1 and low counts in Group 4. A positive correlation between surface roughness and colony counts was obtained, however, was not statistically significant.

CONCLUSIONS: The coated orthodontic brackets exhibited less surface roughness than the uncoated orthodontic brackets. Group 4 coated orthodontic brackets showed the best antibacterial properties.

CLINICAL RELEVANCE: Coated orthodontic brackets prevent adhesion of streptococcus mutans and reduces plaque accumulation around the brackets thereby preventing formation of white spot lesions during orthodontic treatment.

ABSTRACT

Single Port (SP) robotic partial nephrectomy (RPN) can be performed via retroperitoneal and transperitoneal approach. We aim to compare outcomes of two commonly described incisions for retroperitoneal SP RPN: lateral flank approach (LFA) and low anterior access (LAA). We performed a retrospective study of patients who underwent SP retroperitoneal RPN from 2018 to 2023 as part of a large multi-institute collaboration (SPARC). Baseline demographic, clinical, tumor-specific characteristics, and perioperative outcomes were compared using χ2, t test, Fisher exact test, and Mann-Whitney U test. Multivariable analyses were conducted using robust and logistic regressions. A total of 70 patients underwent SP retroperitoneal RPN, with 44 undergoing LAA. Overall, there were no significant differences in baseline characteristics between the two groups. The LAA group exhibited significantly lower median RENAL scores (8 vs. 5, p < 0.001) and more varied tumor locations (p = 0.002). In the bivariate analysis, there were no statistically significant differences in ischemia time, estimated blood loss, or complication rates between the groups. However, the LAA group had longer operative times (101 vs. 134 min, p < 0.001), but was more likely to undergo a same-day discharge (p < 0.001). When controlling for other variables, LAA was associated with shorter ischemia time (p = 0.005), but there was no significant difference in operative time (p = 0.348) and length of stay (p = 0.122). Both LFA and LAA are acceptable approaches for SP retroperitoneal RPN with comparable perioperative outcomes. This early data suggests the LAA is more versatile for varying tumor locations; however, larger cohort studies are needed to ascertain whether there is an overall difference in patient recovery.

ABSTRACT

INTRODUCTION: This systematic review aims to evaluate the use of machine learning and artificial intelligence in hernia surgery.

METHODS: The PRISMA guidelines were followed throughout this systematic review. The ROBINS-I and Rob 2 tools were used to perform qualitative assessment of all studies included in this review. Recommendations were then summarized for the following pre-defined key items: protocol, research question, search strategy, study eligibility, data extraction, study design, risk of bias, publication bias, and statistical analysis.

RESULTS: A total of 13 articles were ultimately included for this review, describing the use of machine learning and deep learning for hernia surgery. All studies were published from 2020 to 2023. Articles varied regarding the population studied, type of machine learning or Deep Learning Model (DLM) used, and hernia type. Of the thirteen included studies, all included either inguinal, ventral, or incisional hernias. Four studies evaluated recognition of surgical steps during inguinal hernia repair videos. Two studies predicted outcomes using image-based DMLs. Seven studies developed and validated deep learning algorithms to predict outcomes and identify factors associated with postoperative complications.

CONCLUSION: The use of ML for abdominal wall reconstruction has been shown to be a promising tool for predicting outcomes and identifying factors that could lead to postoperative complications.

ABSTRACT

BACKGROUND: Data about necessity of performing transesophageal echocardiography (TOE) prior to every catheter ablation (CA) of atrial fibrillation (AF) is scarce. We aimed to evaluate the safety of an individualized risk-based approach to TOE with respect to thromboembolic cerebrovascular events (CVE) in patients undergoing CA for AF or left atrial tachycardia (AT).

METHODS: We performed a retrospective clinical study based on our institutional registry database. Patients undergoing CA for AF or left-sided AT following initial AF ablation at two participating centers were enrolled. Prior to the procedure, patients were scheduled for TOE only if they had a history of thromboembolic stroke, left atrial appendage (LAA) thrombus, or inappropriate anticoagulation regimen in the previous 3 to 4 weeks. The incidence of periprocedural cerebrovascular thromboembolic events was assessed.

RESULTS: We analyzed 1155 patients (median age 70 years, 54.8% male, 48.1% had persistent AF/AT). In 261 patients, a TOE was performed; in 2 patients (0.7%), an LAA thrombus was detected, which led to cancellation of the catheter ablation; in 894 patients, the TOE was omitted. Of the 1153 (0.35%) patients who underwent ablation, 4 (0.35%) experienced a CVE (one TIA and three strokes). The rate of CVE in our study does not exceed that reported in most multicenter trials. The low event rates limited statistical analysis of possible risk factors for CVE. In all 4 patients with CVE, post-CVE imaging showed the absence of LAA thrombus.

CONCLUSIONS: An individualized selective approach to TOE before catheter ablation of AF or left AT showed a very low risk of overt intraprocedural thromboembolic events for the population in our study. A further randomized controlled study is needed to determine whether TOE prior to catheter ablation without ICE could be omitted in patients with uninterrupted OAC without previous thromboembolic events or a history of left atrial thrombus.

ABSTRACT

To investigate the correlation between quantitative plaque parameters, the perivascular fat attenuation index, and myocardial ischaemia caused by haemodynamic impairment. Patients with stable angina who had invasive flow reserve fraction (FFR) assessment and coronary artery computed tomography (CT) angiography were retrospectively enrolled. A total of 138 patients were included in this study, which were categorized into the FFR < 0.75 group (n = 43), 0.75 ≤ FFR ≤ 0.8 group (n = 37), and FFR > 0.8 group (n = 58), depending on the range of FFR values. The perivascular FAI and CTA-derived parameters, including plaque length (PL), total plaque volume (TPV), minimum lumen area (MLA), and narrowest degree (ND), were recorded for the lesions. An FFR < 0.75 was defined as myocardial-specific ischaemia. The relationships between myocardial ischaemia and parameters such as the PL, TPV, MLA, ND, and FAI were analysed using a logistic regression model and receiver operating characteristic (ROC) curves to compare the diagnostic accuracy of various indicators for myocardial ischaemia. The PL, TPV, ND, and FAI were greater in the FFR < 0.75 group than in the grey area group and the FFR > 0.80 group (all p < 0.05). The MLA in the FFR < 0.75 group was lower than that in the grey area group and the FFR > 0.80 group (both P < 0.05). There were no significant differences in the PL, TPV, or ND between the grey area and the FFR > 0.80 group, but there was a significant difference in the FAI. The coronary artery lesions with FFRs ≤ 0.75 had the greatest FAI values. Multivariate analysis revealed that the perivascular FAI and PL density are significant predictors of myocardial ischaemia. The FAI has some predictive value for myocardial ischaemia (AUC = 0.781). After building a combination model using the FAI and plaque length, the predictive power increased (AUC, 0.781 vs. 0.918), and the change was statistically significant (P < 0.001). The combined model of PL + FAI demonstrated great diagnostic efficacy in identifying myocardial ischaemia caused by haemodynamic impairment; the lower the FFR was, the greater the FAI. Thus, the PL + FAI could be a combined measure to securely rule out myocardial ischaemia.
