To identify the parents' perspective of fall incidence and risks in the pediatric ambulatory environment.

A prospective descriptive correlational study was conducted in two large quaternary pediatric hospitals. Parents who accompanied their children to the clinic appointment were surveyed about falls their child experienced while at the clinic. Parent reported falls were compared to those reported in adverse event reporting systems (AERS) for the same period.

Data from 2327 completed parent surveys were analyzed. Parents reported 48 children fell and 139 falls. Only three falls were recorded in the AERS. Stepwise logistic regression was used to identify predictors of falls and a nomogram was created from the final model to facilitate patient fall risk screening. Three predictors of falls were identified children under the age of five, children described by their parents as falling more at home than other children of the same age, and children who had a medical condition that impacts their ability to walk. A nomogram is provided to estimate the probability of falling for patients under 18years of age in the ambulatory environment.

Parents may provide more reliable data regarding the incidence and risk factors for falls in the ambulatory environment than AERS, and it is possible to predict the probability of a fall given information from the parents.

Knowing who is at risk for falls creates opportunities for organizations to modify clinic procedures, train staff, and create physical environments that promote increased patient safety.

Environmental and genetic factors in various colonic pathologies influence the onset and outcome of diseases. As the evidence from recent research is considered, the importance of inflammation in the onset, progression, and outcome is gaining more traction. The goal of this study was to see if pirfenidone could treat ulcerative colitis (UC) and if so, what mechanisms were involved. By intracolonic instillation [2 ml, 3 percent v/v acetic acid (AA)], ulcerative colitis was induced. Pirfenidone was administered to rats in different experimental groups (125 or 250 and 500 mg/kg, orally) for two weeks. Compared to normal group, the AA group showed an increase in colon weight, length, body weight, clinical evaluation, and macroscopic scoring of UC, serum lactate dehydrogenase, C-reactive protein, malondialdehyde, while decreasing serum total antioxidant capacity. Significant increases in colon Jun N terminal kinase1 (JNK1), transforming growth factor-beta (TGF-β1), interleukin 1 beta (IL1β), and Caspase-3 content. Furthermore, immunohistochemical staining revealed increased nuclear factor kappa B (NF-κB) expression along with histopathological changes. Pirfenidone inhibited inflammatory biomarkers release and restored oxidants/antioxidants hemostasis. In a dose-dependent manner, pirfenidone treatment showed a significantly decrease in all of these parameters. In addition, pirfenidone has significantly preserved the histopathological architecture of tissues. learn more Current data demonstrate that Pirfenidone protects against AA-induced UC by modulating the TGF-β1/JNK1 and Caspase-3 pathways. Pirfenidone's antioxidant, anti-inflammatory, and anti-apoptotic properties are thought to be responsible for its therapeutic benefit.

Alopecia areata (AA) is a chronic disorder and the best treatment regimen for it is unknown. Currently, one of the best documented treatment modalities for AA is topical immunotherapy.

To evaluate the safety and efficacy of a novel method (multi-concentration patch test) versus standard protocol for topical immunotherapy.

A prospective randomized clinical trial was conducted on 30 patients with Alopecia areata, half of them received DPCP with a novel method using multi-concentration patch test to determine the optimal initiating concentration of DPCP (case group) and the other half experienced immunotherapy according to the standard protocol (control group). Percentage of hair regrowth after 6months of treatment and the incidence of drug-related adverse effects were evaluated and compared between the two groups. (IRCT registration code IRCT20141209020250N5).

Absolute and relative hair regrowth percentages were reported 25% and 41.49% in case group and 8.2% and 14.21% in control group respectively. Considerable response (more than 75% hair regrowth) was observed in 4 (26.6%) patients in case and 1 (6.6%) patient in control group. The clinical response was initiated about 7weeks sooner in case compared to the control group (14 versus 7.38weeks, P 0.001). Overall, clinical response was higher in patients received new protocol, compared to control group. Moreover, patients who experienced new protocol had a higher level of treatment satisfaction in comparison with patients having standard protocol (P 0.012).

This study revealed the effectiveness and safety of the novel multi-concentration patch test DPCP therapy for AA and its priority to conventional method, at least in terms of shortened duration of DPCP immunotherapy.

Systemic lupus erythematosus (SLE) is a common autoimmune disease, which can cause multiple organ damage. Numerous studies have shown that immune factors have important roles in the pathogenesis of both COVID-19 and SLE. In the early stages of COVID-19 and SLE pathogenesis, IFN-α expression is frequently increased, which aggravates the virus infection and promotes SLE development. In addition, increased IL-6 levels, caused by different mechanisms, are observed in the peripheral blood of patients with severe COVID-19 and SLE, stimulating a series of immune cascades that lead to a cytokine storm, as well as causing B cell hyperfunction and production of numerous of antibodies, aggravating both COVID-19 and SLE. In this review, we explore the background immunopathological mechanisms in COVID-19 and SLE and analyze the advantages and disadvantages of commonly used SLE drugs for patients with COVID-19, to optimize treatment plans for patients with SLE who develop COVID-19.Bone marrow (BM) examination is an essential step in both diagnosing and managing numerous hematologic disorders. BM nucleated differential count (NDC) analysis, as part of BM examination, holds the most fundamental and crucial information. However, there are many challenges to perform automated BM NDC analysis on whole-slide images (WSIs), including large dimensions of data to process, complicated cell types with subtle differences. To the authors best knowledge, this is the first study on fully automatic BM NDC using WSIs with 40x objective magnification, which can replace traditional manual counting relying on light microscopy via oil-immersion 100x objective lens with a total 1000x magnification. In this study, we develop an efficient and fully automatic hierarchical deep learning framework for BM NDC WSI analysis in seconds. The proposed hierarchical framework consists of (1) a deep learning model for rapid localization of BM particles and cellular trails generating regions of interest (ROI) for further .Incorporating shape information is essential for the delineation of many organs and anatomical structures in medical images. While previous work has mainly focused on parametric spatial transformations applied to reference template shapes, in this paper, we address the Bayesian inference of parametric shape models for segmenting medical images with the objective of providing interpretable results. The proposed framework defines a likelihood appearance probability and a prior label probability based on a generic shape function through a logistic function. A reference length parameter defined in the sigmoid controls the trade-off between shape and appearance information. The inference of shape parameters is performed within an Expectation-Maximisation approach in which a Gauss-Newton optimization stage provides an approximation of the posterior probability of the shape parameters. This framework is applied to the segmentation of cochlear structures from clinical CT images constrained by a 10-parameter shape model. It is evaluated on three different datasets, one of which includes more than 200 patient images. The results show performances comparable to supervised methods and better than previously proposed unsupervised ones. It also enables an analysis of parameter distributions and the quantification of segmentation uncertainty, including the effect of the shape model.Accurate dating of bone fractures can be crucial in the context of forensic trauma analysis since it may provide essential information for the corroboration or contradiction of statements by victims or suspects in cases of domestic abuse or torture. The different stages of bone healing have been well described in the existing literature, and some previous studies attempted to define related timelines particularly in the paediatric population. However, the bone healing process can be very variable and despite the importance of the topic in the forensic field, so far little is known about the radiological appearance of bone fractures at different healing stages, and how this correlates with time, especially in an adult population. The aim of this retrospective observational study was to describe the temporal aspect of pre-defined healing stages as they appear on radiographs of tubular bone fractures in adults, and explore the effect of potential cofounding variables. A dynamic nomogram was developed as a user-friendly tool to be eventually applied in clinical or medico-legal settings. This study showed that the posttraumatic time interval (PTTI) increased progressively with the pre-defined healing stages. However, confounding factors, such as patients' age, sex, and location of the fracture need to be accounted for in the final estimation model. Further studies are needed to explore more potentially confounding variables to refine the presented outcomes. Better knowledge of the effect of different confounding variables in the dating of fracture healing will contribute to greater accuracy of PTTI estimation of bone fractures in adults.

Inherited or acquired arrhythmic disorders and cardiac disease have been associated with sudden cardiac death (SCD) in dogs. The electrical mechanism related to death in most of these cases is unknown. This retrospective study aimed to describe arrhythmic events in dogs that experienced SCD during Holter monitoring.

Nineteen client-owned dogs that experienced SCD during Holter examination were included. Clinical records from a Holter service database were reviewed, and both the rhythm preceding death and the dominant rhythm causing SCD were analysed. Clinical data, Holter diaries and echocardiographic diagnosis were also evaluated.

Structural heart disease was identified in 12/19 dogs (dilated cardiomyopathy in five dogs, arrhythmogenic right ventricular cardiomyopathy in four dogs, myxomatous mitral valve disease in two dogs, and suspected myocarditis in one dog), five of which had concurrent congestive heart failure. Sudden cardiac death was related to ventricular premature complexes or monomorphic ventricular tachycardia degenerating into ventricular fibrillation in 42% of dogs, polymorphic ventricular tachycardia, or torsade de pointes-like inducing ventricular fibrillation in 21%, and asystole or presumptive agonal pulseless electrical activity triggered by malignant bradyarrhythmias in 37%.
