Understanding metabolic cost through biomechanical data, including ground reaction forces (GRFs) and joint moments, is vital for health, sports, and rehabilitation. The long stabilization time (2-5 min) of indirect calorimetry poses challenges in prolonged tests. This study investigated using artificial neural networks (ANNs) to predict metabolic costs from the GRF and joint moment time series.

Alkylated polycyclic aromatic hydrocarbons (PAHs) are abundant constituents of many PAH mixtures and contribute to risk at contaminated sites. Despite their abundance, the movement of alkylated PAHs remains understudied relative to unsubstituted PAHs. In the present study, passive sampling devices were deployed in the air, water, and sediments at 11 locations across multiple seasons to capture spatial and temporal variability in the abundance and movement of alkylated PAHs at a Brownsfield creosote site in Oregon, USA.

Nuclear Alpha-Synuclein in Parkinson's Disease and the Malignant Transformation in Melanoma.

Neurol Res Int

January 2025

Departamento de Bioquímica, Facultad de Medicina, Universidad Autónoma de San Luis Potosí, San Luis Potosi, Mexico.

Alpha-synuclein (ASyn), a marker of Parkinson's disease (PD) and other neurodegenerative processes, plays pivotal roles in neuronal nuclei and synapses. ASyn and its phosphorylated form at Serine 129 (p-ASyn) are involved in DNA protection and repair, processes altered in aging, neurodegeneration, and cancer. To analyze the localization of p-ASyn in skin biopsies of PD patients and melanoma.

Unlabelled: The increased rate of anterior cruciate ligament (ACL) tears has led to a greater number of revisions. Revision surgery can be performed in one or two stages. Single-stage revision ACL reconstruction (ssRACLR) may be performed when prior tunnels can be re-used or bypassed whereas a two-stage procedure is indicated when bone grafting of dilated tunnels prior to revision is necessary.

Objectives: Hypoglossal nerve stimulation (HGNS) is a promising surgical option for patients with obstructive sleep apnea (OSA) who are intolerant of continuous positive airway pressure therapy (CPAP). Efficacy studies for HGNS stimulation largely focus on the apnea-hypopnea index and/or oxygen desaturation index. This study's objective was to show the physiological effects of HGNS stimulation on upper airway patency, airflow, and treatment effect during polysomnography (PSG) testing.

Introduction: This was the first phase 1 study conducted in the United States. It consisted of dose-escalation (part A) and multiple indication-specific cohort expansion (part B), investigating the safety and preliminary efficacy of toripalimab (anti-programmed cell death-1 inhibitor) in patients with advanced malignancies.

Methods: Patients with advanced malignancies that progressed after treatment with at least one prior line of standard systemic therapy, including the patients with advanced/recurrent cholangiocarcinoma (CCA), received toripalimab 240 mg every 3 weeks in part B.

Introduction: Uveal melanoma remains a disease with aggressive behavior and poor prognosis despite advances in clinical management. Because monotherapy with immune checkpoint inhibitors has led to limited improvement in response rates, combination with other agents that act on the biological basis of oncogenesis has been proposed as a possible therapeutic strategy.

Methods: We designed a phase 1b trial to test the safety and tolerability of selinexor in combination with immune checkpoint inhibitors in patients with advanced uveal melanoma.

Pros and Cons of Inpatient SGLT2i Use for Hyperglycemia and Heart Failure.

J Endocr Soc

January 2025

Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, Division of Endocrinology, Diabetes and Metabolism, Long Island Jewish Medical Center, Northwell Health, New Hyde Park, NY 11040, USA.

Sodium-glucose cotransporter 2 inhibitors (SGLT2is), originally approved by the US Food and Drug Administration for glycemic control in type 2 diabetes mellitus (DM2), have shown substantial cardiovascular and renal benefits, leading to their expanded use in managing heart failure (HF) and chronic kidney disease in the outpatient setting. Despite these benefits, their use for inpatient hyperglycemia management is not universally endorsed due to safety concerns and inadequate data. However, emerging evidence suggests potential advantages of initiating SGLT2i treatment for patients during hospitalization in the setting of HF.

Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities and their metabolites. When a probiotic feed is combined with a biofloc system, the production amount may be improved through better fish growth, disease resistance, and/or improved water quality by reducing organic matter and stabilizing metrics such as pH and components of the nitrogen cycle.

Impact of Order Restrictions on Hemoglobin A1c Requests at Primary Health Care Centers in Riyadh, Saudi Arabia.

Risk Manag Healthc Policy

January 2025

Department of Family Medicine, King Abdulaziz Medical City, Ministry of National Guard Health Affairs, Riyadh, Saudi Arabia.

Purpose: The aim of the study was to assess the effect of policy intervention on the physician ordering of HbA1c for the patients seen at the primary health care center in Riyadh, Saudi Arabia.

Methods: The study included patients over the age of 18 for whom HbA1c tests were ordered before and after the policy restrictions were implemented at the three main Primary Health Care Centers under the Ministry of National Guard Health Affairs (MNGHA) in Riyadh, between October 2020 and August 2023. Several data management steps and restrictions were carried out to identify the patients seen before and after the intervention and controlled for the confounders.

Digital technologies can help support the health of migrants and refugees and facilitate research on their health issues. However, ethical concerns include security and confidentiality of information; informed consent; how to engage migrants in designing, implementing and researching digital tools; inequitable access to mobile devices and the internet; and access to health services for early intervention and follow-up. Digital technical solutions do not necessarily overcome problems that are political, social, or economic.

Background: Robotic-assisted spinal surgery has reportedly improved the accuracy of instrumentation with smaller incisions, improving surgical outcomes and reducing hospital stay. However, robot-assisted spine surgery has thus far been confined to placement of pedicle screw instrumentation only. This pilot study aims to explore the feasibility of utilizing the Mazor™ X Stealth Edition (Medtronic, Sofamor Danek USA), robotic-arm platform in the minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) procedure inclusive of interbody cage placement, in our institution.

Anterior lumbar interbody fusion (ALIF) is an anterior surgical approach for interbody fusion in the lumbar spine which affords the surgeon unfettered access to the disc space and allows for release of the anterior longitudinal ligament and insertion of a large, lordotic interbody graft. Despite the benefits associated with ALIF when compared with other lumbar interbody fusion techniques, the ALIF approach is associated with a number of unique complications, and certain patient-specific criteria (e.g.

Background: Surgical treatment of therapy-resistant radiculopathy associated with lumbar herniated discs in patients with extreme obesity is a challenge for neurosurgeons. In addition to technical problems in surgery due to the abundant subcutaneous adipose tissue and perioperative risks, there are significant anesthetic risks when anesthesia is performed with a patient in the prone position. A surgical procedure should preferably be minimally traumatic and quick with minimal risks of complications.

Vector AutoRegressive Moving Average (VARMA) models form a powerful and general model class for analyzing dynamics among multiple time series. While VARMA models encompass the Vector AutoRegressive (VAR) models, their popularity in empirical applications is dominated by the latter. Can this phenomenon be explained fully by the simplicity of VAR models? Perhaps many users of VAR models have not fully appreciated what VARMA models can provide.
