Insights From the ISASS Webinar Series on Current and Emerging Techniques in Endoscopic Spine Surgery | Part 1: Polytomous Rasch Analysis of Surgeon Endorsement of Endoscopic Discectomy/Foraminotomy, Interbody Fusion, and Importance of Patient Feedback During Surgery.

Background: The International Society for the Advancement of Spine Surgery hosted the first of a series of 4 webinars on endoscopic spine surgery techniques, focusing on end§oscopic discectomy, foraminotomy, instrumented endoscopic fusion, standalone lumbar interbody fusion with innovative materials, and the role of patient feedback in awake procedures. This series aims to share knowledge and discuss the complexities and clinical evidence of modern endoscopic spine surgery.

Objective: To analyze the level of surgeon endorsement for the presented endoscopic spine surgery techniques before and after the webinar, utilizing polytomous Rasch analysis, and to evaluate the potential for these insights to inform clinical guideline recommendations.

Two-stage surgical intervention for a rare case of intersected nasoethmoidal encephalocele and open-lip schizencephaly in an infant: illustrative case.

Background: Schizencephaly and encephaloceles are rare developmental birth defects, with the former involving abnormal clefts in the cerebral hemispheres connected to the ventricular system and the latter involving a neural tube defect characterized by the protrusion of brain tissue through an abnormal skull opening. These conditions are individually uncommon, and their simultaneous occurrence in a single patient is exceedingly unusual.

Observations: This case report explores the intersection of these two rare congenital malformations in a 2-month-old female patient from an indigenous community in a rural area of Colombia.

Over-the-counter short-acting β-agonist purchase and asthma-related health outcomes: a post hoc analysis of the SABINA III study.

This post-hoc analysis of the SABINA III study evaluated the association of short-acting β-agonist (SABA) prescriptions and self-reported over-the-counter (OTC) SABA purchase in the previous 12 months with asthma-related outcomes using multivariable regression models in 4556 patients (mean age, 48.9 years). Of the 2810 patients prescribed ≥3 SABA canisters, 776 (27.

The Epidemiological Impact of Dengue in Colombia: A Systematic Review.

Dengue is the most important viral vector-borne disease in the tropics, with Colombia being one of the most affected countries. In this context, it is essential to identify and synthesize the existing evidence on the epidemiology of dengue in Colombia. A systematic review (PROSPERO CRD42021257985) was conducted by searching for epidemiological data in populations with suspected or confirmed dengue in Colombia from 2012 to 2020.

Objectives: To understand the meaning of the experiences of breast cancer patients undergoing diagnostic and treatment processes.

Material And Methods: A descriptive qualitative study based on the hermeneutic-interpretative scientific paradigm and grounded in a phenomenological epistemological framework. The study included women aged 18 years or older diagnosed with breast cancer and treated at a university clinic in Bogotá, who were given a semi-structured interview.

Gastric signet ring cell adenocarcinoma metastatic to the breast. Systematic review of the literature, regarding a case.

Objectives: To determine the general state of scientific evidence published in the last 20 years on gastric signet ring cell (SRC) adenocarcinoma metastatic to the breast, and present a case.

Material And Methods: The case of a patient who attended a high-complexity reference institution in Bogotá for a breast metastasis from a gastric SRC adenocarcinoma is reported. A Systematic Review of the literature was carried out, including cohort studies, reports and case series of patients with gastric SRC adenocarcinoma metastatic to the breast, which will present information on the epidemiology, clinical, radiological and histopathological characteristics, and the treatment and prognostic of this disease.

Challenges and Opportunities in COPD Management in Latin America: A Review of Inhalation Therapies and Advanced Drug Delivery Systems.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, particularly in low- and middle-income countries, where it poses a significant burden. In Latin America, the estimated prevalence of COPD is notably high, but the management and treatment of the disease have progressed slowly. This review examines the current status of inhalation therapy for COPD in Latin America, focusing on pharmacological therapies, inhalation devices, and the potential of advanced drug delivery systems.

Understanding the Dry Eye Disease-Related Symptoms in South America: Prevalence and Associated Factors-A Systematic Review.

: Dry eye disease is a leading cause of ophthalmologic consultations worldwide and can significantly impact quality of life. While global prevalence rates vary widely, data specific to South America are limited. This systematic review aims to describe and analyze the prevalence and associated factors of dry eye disease-related symptoms in South American populations.

Why Research From Lower- and Middle-Income Countries Matters to Evidence-Based Intervention: A State of the Science Review of ACT Research as an Example.

Despite the global nature of psychological issues, an overwhelming majority of research originates from a small segment of the world's population living in high-income countries (HICs). This disparity risks distorting our understanding of psychological phenomena by underrepresenting the cultural and contextual diversity of human experience. Research from lower- and middle-income countries (LMIC) is also less frequently cited, both because it is seemingly viewed as a "special case" and because it is less well known due to language differences and biases in indexing algorithms.

Influence of Heat Treatment Temperature on Microstructure, Hardness and Sensitization of UNS S32205 Duplex Stainless Steel.

Improper thermal cycles on duplex stainless steels can lead to the formation of detrimental phases or alter the proportion of ferrite and austenite phases, thus influencing the material's mechanical properties and corrosion resistance. Therefore, this study aimed to evaluate the effect of aging (at 850 and 950 °C) and solubilization (at 1000 and 1150 °C) thermal treatments on microstructure, indentation hardness, elasticity modulus, and susceptibility to intergranular corrosion of UNS S32205 duplex stainless steel. The sigma phase (σ) formation in the aged samples, with hardness values between 8 and 10 GPa, was confirmed.

Construction of an immune gene expression meta signature to assess the prognostic risk of colorectal cancer patients.

Despite recent advancements in colorectal cancer (CRC) treatment, particularly with the introduction of immunotherapy and checkpoint inhibitors, the efficacy of these therapies remains limited to a subset of patients. To address this challenge, our study aimed to develop a prognostic biomarker based on immune-related genes to predict better outcomes in CRC patients and aid in treatment decision-making. We comprehensively analysed immune gene expression signatures associated with CRC prognosis to construct an immune meta-signature with prognostic potential.

Fetal Diagnosis of a Ductus Arteriosus Aneurysm: A Case Report.

The ductus arteriosus aneurysm (DAA) is considered a rare anatomical alteration that consists of a dilation of this vascular structure. It has been reported that the DAA can resolve in the immediate postnatal stage and do not generate any consequences for the neonate. However, have been described some cases in which the DAA is complicated due to thromboembolic events, rupture of the lesion, respiratory symptoms, and even death.

Changes in Periodontal Tissues With Periodontally Accelerated Orthodontics: A Systematic Review and Meta-Analysis.
