Digital dermatitis in dairy cattle in Egypt: Herd-level risk factors and Treponema spp. prevalence across lesion M-scores.

Digital dermatitis (DD) is an infectious disease of the digital skin of dairy cows that is associated with compromised animal welfare and significant economic losses. The hind feet of 16,098 dairy cows from 55 herds were examined in the milking parlor, and DD lesions identified were classified using the M-score system and swabbed for PCR testing. Swabs were also collected from hind feet with normal digital skin for comparison.

Simulated microgravity environment inhibits matrix mineralization during the osteoblast to osteocyte differentiation.

This study investigates the effects of microgravity on the differentiation and mineralization of IDG-SW3 osteocyte-like cells to understand the response of bone cells to microgravity and develop strategies to mitigate bone loss in astronauts. IDG-SW3 cells were cultured in collagen-coated dishes and subjected to a 3D clinostat to simulate microgravity 14 days after initiating differentiation. The static group remained under normal gravity.

An abattoir study of the prevalence of foot lesions and claw measurements in water buffalo in Egypt.

Background: Lameness has been associated with compromised animal welfare and reduced productivity in dairy cattle herds worldwide. However, little is known about the prevalence of claw lesions in the dairy buffalo population in Egypt. Furthermore, the optimum measurements for claw trimming in buffalo are unknown.

A cross-sectional study of the prevalence of lameness and digital dermatitis in dairy cattle herds in Egypt.

Background: Lameness is a significant problem for the dairy industry worldwide. No previous studies have evaluated the prevalence of lameness or digital dermatitis (DD) in dairy cattle herds in Egypt. A total of 16,098 dairy cows from 55 dairy herds in 11 Egyptian governorates underwent visual locomotion scoring using a 4-point scoring system.

Stakeholder Perspectives on the Impact of COVID-19 on the Implementation of a Community-Clinic Linkage Model in New York City.

Community-clinical linkage models (CCLM) have the potential to reduce health disparities, especially in underserved communities; however, the COVID-19 pandemic drastically impacted their implementation. This paper explores the impact of the pandemic on the implementation of CCLM intervention led by community health workers (CHWs) to address diabetes disparities among South Asian patients in New York City. Guided by the Consolidated Framework for Implementation Research (CFIR), 22 stakeholders were interviewed: 7 primary care providers, 7 CHWs, 5 community-based organization (CBO) representatives, and 3 research staff.

Local administration of HMGB-1 promotes bone regeneration on the critical-sized mandibular defects in rabbits.

Reconstruction of a critical-sized osseous defect is challenging in maxillofacial surgery. Despite novel treatments and advances in supportive therapies, severe complications including infection, nonunion, and malunion can still occur. Here, we aimed to assess the use of a beta-tricalcium phosphate (β-TCP) scaffold loaded with high mobility group box-1 protein (HMGB-1) as a novel critical-sized bone defect treatment in rabbits.

Clinical outcomes are associated with changes in ultrasonographic structural appearance after platelet-rich plasma treatment for knee osteoarthritis.

Background: Hyaluronic acid (HA) and platelet-rich plasma (PRP) are two treatment options used for knee osteoarthritis (KOA) but studies comparing the efficacy of the two yield conflicting results. In addition, the association of clinical outcomes of PRP intra-articular injections with changes in the ultrasonography structural appearance of the knee has not been investigated.

Aim: To compare the efficacy of PRP and HA intra-articular injections as mono-therapeutic options for primary KOA, and to determine whether the clinical outcomes are associated with changes in the ultrasonography structural appearance.

Diagnostic spectrum of ovarian masses in women with breast cancer; magnetic resonance imaging: histopathology correlation.

This study addresses the clinical problem of the patient with breast cancer that has been operated on for an ovarian mass. It specifies the spectrum of histopathologic diagnoses and the differentiating magnetic resonance imaging (MRI) features of ovarian masses with correlations between clinical features, histopathologic, and MRI findings. Sensitivity and specificity of MRI vs histopathology in diagnosing malignancy are estimated.

Omega-3 fatty acids in juvenile idiopathic arthritis: effect on cytokines (IL-1 and TNF-α), disease activity and response criteria.

This study aims to demonstrate the effect of omega-3 fatty acids (ω-3 FAs) supplements on the clinical manifestations, laboratory investigations, disease activity, functional capacity, response criteria as well as interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α) levels in juvenile idiopathic arthritis (JIA) patients. Twenty-seven JIA patients were included in this study. Dietary supplements of ω-3 FAs 2 g/day were given for 12 weeks.

The effect of lead on bone mineral properties from female adult C57/BL6 mice.

Lead toxicity is a significant problem in the U.S. with elevated blood lead levels being highest among very young children and older adults >50 years old.

Weaning children from mechanical ventilation with a computer-driven system (closed-loop protocol): a pilot study.

Objective: To evaluate the applicability, tolerance, and efficacy of a closed-loop protocol to wean children from mechanical ventilation.

Design: Prospective single-center pilot study.

Setting: Tertiary care university hospital.

Gamma-Diketone central neuropathy: quantitative analyses of cytoskeletal components in myelinated axons of the rat rubrospinal tract.

Loss of axon caliber is a primary component of gamma-diketone neuropathy [LoPachin RM, DeCaprio AP. gamma-Diketone central neuropathy: axon atrophy and the role of cytoskeletal protein adduction. Toxicol Appl Pharmacol 2004;199:20-34].
