The present study investigated the effects of colchicine treatment on leaf length, leaf width, and leaf area index (LAI) in two species of Acha (fonio), namely Digitaria exilis and Digitaria iburua. Colchicine, a potent mitotic inhibitor, has been widely used to induce polyploidy and in studying the effects of genome duplication on various morphological traits. This study aimed to explore if colchicine treatment could alter the leaf morphology of the two Acha species. Seeds of the two species were treated with colchicine solution at various concentrations (0.05, 0.10, 0.15, and 0.20 g/dL), while a control group was maintained without any treatment. Leaf length and width were measured using a meter rule, and LAI was calculated by multiplying the leaf length and leaf width with the constant for both species. Statistical analysis was performed using the Analysis of Variance on SPSS to determine significant differences between treated and control groups. The results showed that colchicine treatment had a significant effect on leaf morphology in both Acha species. Leaf length and width increased significantly in response to colchicine treatment, with the degree of increase depending on the concentration. Moreover, the LAI also exhibited a significant increase in treated plants compared to the control group. Colchicine concentration level of 0.10 g/dLproduced the best results that can be exploited to enhance the morphological characteristics of both Acha species. The findings suggest that colchicine-induced polyploidy can enhance leaf growth and overall leaf area in Acha plants, leading to potential implications for agricultural productivity and yield improvement. Further studies are needed to elucidate the underlying mechanisms and long-term effects of colchicine-induced polyploidy on other growth parameters, reproductive traits, and yield in Acha. Understanding the genetic and physiological changes associated with polyploidy in Acha species will contribute to the development of improved breeding strategies and cultivation practices for this important cereal crop.

Leiomyosarcoma is a malignant smooth-muscle tumor that has a predilection for the gastrointestinal and female genital tract and is a rare entity in the paranasal sinuses. It is locally fast-spreading and highly aggressive, and the prognosis is poor. We report a rare case of leiomyosarcoma of the maxilla in a patient who sought treatment for maxillary swelling, nasal obstruction with no epistaxis, orbital involvement or cervical lymph node metastasis. The patient underwent total maxillectomy followed by radiotherapy. At present after 5 years of follow up, he is symptom free with no recurrence.

Introduction: Total hip arthroplasty is a procedure widely performed in orthopedics, as it is capable of restoring function in the hips, severely affected by orthopedic diseases, such as osteoarthritis and consequently reducing pain and restoring function. Objective: To identify the effects of physical therapy in the postoperative period of total hip arthroplasty. Method: This is an integrative review, of an exploratory and descriptive nature, carried out between January and May 2024 and guided by the recommendations of the Joanna Brigs Institute. The Pubmed, LILACS, and SciELO databases were used. The following descriptors were used for the search procedure: “Physiotherapy and hip arthroplasty”. For the operationalization of the search, the Boolean descriptor “AND” was used to cross the descriptors. Articles were included in randomized clinical trials, published in full, without restriction of language and/or year of publication, which dealt with the theme addressed and that responded to the objective of the study. On the other hand, editorial letters, any type of literature review, articles unavailable at the time of search, abstracts and/or full articles published in annals of scientific events, preprints, and articles without abstracts were excluded. Results: After searches in the databases, 108 articles were identified on the platforms, subsequently, all had their titles and abstracts read, then 58 articles were excluded for not meeting the eligibility criteria, leaving 50 articles carefully read in full, after complete reading, only 7 articles composed the final sample. Final considerations: based on the reading and analysis of the articles that were previously selected, it was observed that there is no pre-established protocol among the authors for the postoperative period of hip arthroplasty, but that physical therapy techniques associated with therapist support and an early start are responsible for improving functionality, quality of life, pain reduction and increased muscle strength.

Burnout among clinicians is a pressing concern worldwide, manifesting as emotional exhaustion, depersonalization, and reduced professional efficacy. This article explores the intersection of burnout and allostatic load, the physiological burden resulting from chronic stress, to elucidate the consequences for healthcare providers. Burnout impacts clinicians’ mental and physical health, leading to compromised patient care, reduced job satisfaction, and increased attrition rates. A comparative analysis of recent scholarly works reveals converging evidence on systemic contributors such as excessive workloads, inadequate support systems, and organizational inefficiencies, further compounded by individual vulnerabilities like lack of resilience. These challenges have been exacerbated by the COVID-19 pandemic, which has significantly increased stress levels among healthcare professionals globally. This article synthesizes insights from studies conducted between 2020 and 2024, emphasizing the need for holistic approaches to mitigate burnout. It highlights the physiological underpinnings of allostatic load, including chronic dysregulation of stress-response systems that predispose clinicians to adverse health outcomes like cardiovascular diseases, immune dysfunction, and mental health disorders. To address these issues, the article proposes a multidimensional strategy encompassing organizational reforms, evidence-based interventions, and policy advocacy. Recommendations include reducing administrative burdens, fostering supportive work environments, and integrating wellness programs targeting both systemic and individual stressors. Limitations and directions for future research emphasize the importance of inclusive, longitudinal studies focusing on diverse populations to develop tailored solutions. This comprehensive approach aims to enhance clinician well-being and improve healthcare outcomes globally.

Direct myocardial transplant of HFDSCs (human fetal derived stem cells) by open chest surgical procedure was performed in 10 patients with Heart Failure (HF) due to no ischemic, no chagasic dilated cardiomyopathy. All 10 patients survived the operation. At 40 months, the mean (±SD) NYHA class decreased from 3.4 ± 0.5 to 1.33 ± 0.5 (p = .001); the mean EF increased 31%, from 26.6% ± F) 34.8% ± 7.2% (p = .005); and the mean ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% increase in metabolic equivalents, from 2.46 to 5.63) (p < .0001); the mean LVEDD decreased 15%, from 6.85 ± 0.6 cm to 5.80 ± 0.58 cm (p < .001); mean performance in the 6-minute walk test increased by 43.2%, from 251 ± 113.1 seconds to 360  0 seconds (p = .01); the mean distance increased 64.4%, from 284.4  144.9 m to 468.2 ± 89.8 m (p = .004); and the mean result in the Minnesota test decreased from 71 ± 27.3 to 6 ± 5.9 (p < .001). Six patients survived after 40 months; 5 of them had complete reverse remodeling after 3 months after transplants. The average age at the moment of the transplants was 62 years (s/d 11.6). Results: The first patient died at 5,4 years for an infection; the second patient died at,7,4 years for heart failure; the third patient died at 8,4 years for heart failure; the fourth patient died at 10 years for heart failure and the fifth patient died at 14,4 years after transplant at the age of 83 for heart failure. The average age at the moment of death was 70 years (s/d12.9). The survival rate at 4 years was 100% (K/M) and at 14 years (25%K/M). Conclusion: These initial worldwide experiences with the surgical direct transplant of liver fetal stem cells in patients with end-stage HF shows clearly the positive effect in the reverse remodeling of the left ventricle of 50% of the cohort and excellent long-term results in these types of patients opening a new avenue for treating end-stage HF patients without any other option of treatment.

The stem cell secretome is a collective mixture of soluble and insoluble factors released by stem cells during paracrine communication and/or autocrine signaling. In addition to intracellular communication, these paracrine factors play an integral role in tissue development and generation, acting as the primary driving force in the regenerative properties of stem cells. Despite such great potential of stem cell secretome in therapeutic applications, the lack of secretome-based treatments available for the public at the time of writing is odd and puzzling. Hence, this review aims to provide insights into recent advancements in understanding the stem cell secretome, as well as discuss future possibilities and current limitations that must be overcome for the proper development of secretome-based therapies. Through utilizing the MEDLINE database from the National Library of Medicine® (NLM), we found that while there is much evidence of the therapeutic effects of secretome-based therapy, flaws involving regulations and standardization hinder it from revolutionizing regenerative medicine at present. It is cardinal to emphasize that while secretome-based therapy may be the solution for many untreatable conditions, much research is still required before it is approved for clinical practice.

Stroke is a clinically defined syndrome of acute focal neurological deficit attributed to vascular injury (infarction, hemorrhage) of the central nervous system. Stroke is the second leading cause of death and disability worldwide. Stroke is not a single disease but can be caused by a wide range of risk factors, disease processes and mechanisms. Approximately 15% of strokes worldwide are the result of intracerebral hemorrhage, which can be deep (basal ganglia, brainstem), cerebellar or lobar. A minority (about 20%) of intracerebral hemorrhages are caused by macrovascular lesions (vascular malformations, aneurysms, cavernomas), venous sinus thrombosis or rarer causes.

Double-Positive Patients (DPPs), characterized by the simultaneous presence of Anti-Neutrophil Cytoplasmic Antibody (ANCA) and anti-Glomerular Basement Membrane (anti-GBM) antibodies, represent a rare subset in systemic vasculitis. We present two cases of DPPs with renal involvement and review the existing literature to elucidate the clinical characteristics, histopathological findings, management strategies, and prognostic outcomes associated with this condition. Both cases exhibited renal involvement with rapidly progressive glomerulonephritis, requiring renal replacement therapy. Renal biopsies confirmed crescentic glomerulonephritis with features of both anti-GBM disease and ANCA-associated vasculitis. Management included high-dose glucocorticoids, cyclophosphamide, and consideration of plasma exchanges. Double-positive ANCA and anti-GBM vasculitis pose challenges in management and prognosis. Further research is essential to improve therapeutic strategies for this rare and heterogeneous condition.

Background: SCI Action Canada partnered with researchers to adapt an evidence-based leisure-time physical activity (LPTA) counselling service (Get-in-Motion (GIM). A satellite GIM service called Passez à l’action was established within a French-speaking context for persons with physical disabilities. An understanding of the determinants that infl uenced the implementation and functioning of the GIM service within the Adaptavie context are required to maximize the potential of other community-based LTPA services being successfully introduced in similar organizations. Purpose: The case study objectives are to: 1) describe the characteristics and implementation contexts of two leisure-time physical activity counselling services for Canadians with a physical disability and the adoption process that took place when the protocol was translated to a new context, and 2) elucidate, from the point of view of the service providers, the organizational determinants that could have facilitated and/or hindered the implementation and functioning of these services. Methods: Guided by the Consolidated Framework for Implementation Research, focus groups were held with the directors and staff of each service. Mixed-content and thematic analyses were then used to determine overarching themes. Results: Findings suggest that the presence of service innovators fosters ownership of the service and facilitates ongoing staff training and support. A thoughtful implementation plan should be included as a component of translation between contexts. Conclusions: Lessons learned and recommendations for future translation of similar evidence-based services to additional contexts are discussed.

Background: There is paucity in studies reporting long-term results following anterior cruciate ligament (ACL) rupture. A UK national ligament registry (NLR) designed to collect demographic, clinical and outcome data on patients undergoing ACL reconstruction was launched in 2013. There was therefore an emergent question on the role of such registry as an additional source of evidence. Study aims: A framework analysis aimed to provide a basis for the evaluation of outcomes following ACL management and formulate a structure of the evidence, which can be derived from the registry. Methods: A systematic approach was adopted to select relevant studies. Qualitative thematic and meta-narrative analyses were conducted. Level-1 registry data were recorded for all primary ACL reconstruction procedures from January to June 2016. Registry data content and validity were evaluated. Results: Seven studies were suitable for analyses yet none defined the pattern of meniscal injury following initial treatment. When reported the incidence varied markedly between 23% and 80%. There was evidence of collection of at least one principal outcome measure in at least 85% of participants across all studies. Thematic analysis identified four key domains of outcome measures (1) intervention selection, (2) Knee stability evaluation, (3) Patient reported outcomes, (4) Radiographic evaluation and risk of secondary osteoarthritis. Graft choice, rate of meniscal and chondral injuries and cumulative risk of revision surgery had incomplete and inconsistent reports. Comparison of demographic and clinical data with the first registry report demonstrated: predominately younger patient population; older female patients at time of intervention; and higher incidence of meniscal tears. Conclusions: Registry data driven quality and research improvement open a new paradigm in ACL reconstruction evidence base and future practice. Early observations have consolidated the importance of associated meniscal injuries in the management of ACL rupture. Further work is needed to improve registry data completeness, accuracy and validity. A proposed data migration process using available technologies can help harmonise data collection without the added burden on clinical services.
