Few studies have identified the metabolic consequences of the post-acute phase of nonsevere COVID-19. This prospective study examined metabolic outcomes and associated factors in nonsevere, RT-PCR-confirmed COVID-19. The participants' metabolic parameters, the prevalence of long-term multiple metabolic abnormalities (≥ 2 components), and factors influencing the prevalence were assessed at 1, 3, and 6 months post-onset.

Study Design: Prospective cohort study.

Objectives: To perform a cost-utility analysis and to investigate the clinical outcomes and patient's quality of life after anterior cervical discectomy and fusion (ACDF) to treat cervical spondylosis compared between fusion with polyetheretherketone (PEEK) and fusion with tricortical iliac bone graft (IBG) in Thailand.

Summary Of Background Data: ACDF is one of the standard treatments for cervical spondylosis.

The dynamics of humoral immune responses of patients after SARS-CoV-2 infection is unclear. This study prospectively observed changes in anti-receptor binding domain immunoglobulin G (anti-RBD IgG) and neutralizing antibodies against the Wuhan and Delta strains at 1, 3, and 6 months postinfection between October 2021 and May 2022. Demographic data, clinical characteristics, baseline parameters, and blood samples of participants were collected.

Background: The efficacy of mobile stroke units (MSUs) in improving acute ischemic stroke (AIS) care in developing countries is unknown. We compared performance measures and stroke outcomes in AIS patients between MSU and usual care: emergency medical services (EMS) and walk-in.

Methods: We enrolled patients > 18 years of age with an AIS within 4.

This study aimed to evaluate the efficacy of early antiviral treatment in preventing clinical deterioration in asymptomatic or mildly symptomatic severe acute respiratory syndrome coronavirus 2 infected (COVID-19) patients in home isolation and to share our experiences with the ambulatory management of nonsevere COVID-19 patients. This retrospective study included mild COVID-19 adult patients confirmed by real-time reverse transcription-polymerase chain reaction. They received care via an ambulatory management strategy between July 2021 and November 2021.

This study aimed to assess the clinical characteristics of patients who registered at the Siriraj Favipiravir Clinic and to share our experiences in this comparatively unique clinical setting. This retrospective study included patients who registered at the Siriraj Favipiravir Clinic during August 11, 2021 to September 14, 2021. Included adult patients were those with severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) infection confirmed by antigen test kit (ATK) or real-time reverse transcription-polymerase chain reaction, no favipiravir contraindication, no prior COVID-19 treatment, and not receiving care from another medical facility.

Background: Retinitis pigmentosa (RP) is a progressive inherited retinal disease with great interest for finding effective treatment modalities. Stem cell-based therapy is one of the promising candidates. We aimed to investigate the safety, feasibility, and short-term efficacy of intravitreal injection of bone marrow-derived mesenchymal stem cells (BM-MSCs) in participants with advanced stage RP.

Study Design: Retrospective study.

Purpose: This study aimed to investigate the association of surgical intervention with clinical and quality of life (QoL) outcomes in patients who underwent posterior spinal surgery for lumbar spinal stenosis (LSS) with spinal calcium pyrophosphate dihydrate deposition (SCPPD) versus that in those who underwent the surgery for LSS without SCPPD.

Overview Of Literature: Calcium pyrophosphate (CPP)-associated arthritis is one of the most common types of arthritis.

Background: Aside from antituberculous drugs, anterior radical debridement with fusion has been recommended to eradicate the infectious foci and promote early bone healing in spinal tubercular patients. The addition of spinal instrumentation to stabilize the spine and restore physiologic alignment has also been proposed.

Objective: This study was undertaken to evaluate the effectiveness of the combined posterior instrumentation and anterior spinal fusion procedure.

Objective: To assess agreement in detection of lumbar disc herniation (LDH) between limited and full protocol MRI.

Material And Method: 123 patients who requested lumbar MRI for diagnosis of disc herniation were assessed The full protocol MRI composed of sagittal T1-wi, sagittal T2-wi and axial T2-wi was performed on each patient. The sagittal T2-wi was selected as the limited protocol MRI.
