Article Abstract

According to the newest version of NCCN Clinical Practice Guidelines for Non-Small Cell Lung Cancer (NSCLC), increasing attentions are paid to the role of nodal status and other high-risk factors, including vascular invasion, wedge resection, tumors > 4 cm, visceral pleural involvement, and incomplete lymph node sampling in the individual clinical treatment. Precise definitions of T status and N status, closely associated with prognosis and treatment, are worth expanding further. However, complexity arises because no unity definition exists regarding individual T and N descriptors. In an attempt to explore the potential prognostic values of the T status and N status, we systematically review relevant literature and found that there still remained some disputes about the definitions and prognosis. The adjacent lobe invasion regarded as T2 or T3 has not been reached consensus yet so far. Lymph node spread patterns are associated with the treatment strategies of NSCLC. This review mainly focus on the role of T status and N status and tried to seek appropriate and individual treatment strategies in NSCLC.

Our research aims to ascertain the value of precursor and outgrowth lepidic in aiding the confirmation of multiple lung adenocarcinomas as separate primary lung cancers (SPLC). A total of 151 patients with metachronous multiple invasive adenocarcinomas were included in this study. Driver mutation tests(at least five genes: EGFR, ALK, KRAS, BRAF, and ROS1) were conducted on 302 tumors collected from 151 patients.

Objective: It is important to raise awareness of the nutritional problems that can be overlooked during the follow-up visits with children who suffer from neuromuscular diseases, as these dietary differences may lead to additional neurological and systemic problems and impair the quality of life of the patient. The aim of this study was to evaluate the nutritional status of children with neuromuscular disorders and to prevent possible complications by recognizing possible nutritional problems in advance.

Methods: Patients who applied to the outpatient clinic at Cukurova University, Faculty of Medicine, Department of Pediatric Neurology beginning in April 2022 with a neuromuscular disorder diagnosis were followed up with and were included in the study.

Candidate Cytokine Biomarkers for the Diagnosis of Ocular- and Neurosyphilis.

Ocul Immunol Inflamm

September 2025

Division of Ophthalmology, Faculty of Medicine and Health Sciences, Stellenbosch University, Cape Town, South Africa.

Purpose: To describe differences in the expression of selected host biomarkers, by analysing the aqueous humour (AH), cerebrospinal fluid (CSF) and serum of patients with ocular syphilis, both with and without neurosyphilis and HIV infection, to support the diagnosis of ocular syphilis.

Methods: A prospective observational descriptive study was conducted at Tygerberg Academic Hospital in Cape Town, South Africa, from February 1, 2018, to January 31, 2021. The study included all patients aged 18 years or older who presented to the eye clinic with ocular syphilis, provided they had a positive serum Treponema pallidum antibodies (TPA) test, an RPR titre of ≥ 8 and confirmed ocular inflammation.

Background Although advances in care have improved cystic fibrosis (CF) outcomes in higher-income countries (HICs), the situation remains alarming in lower-income countries (LICs). Methods People with CF (pwCF) enrolled in the European Cystic Fibrosis Society Patient Registry (ECFSPR) and carrying at least one F508del variant allele were evaluated in 2017 and in 2022 for predicted percent forced expiratory volume (ppFEV1), underweight status, and chronic Pseudomonas aeruginosa (Pa) infection, according to the gross national income (GNI) per capita divided into three terciles (low-income countries, LICs; middle-income countries, MICs; and high-income countries, HICs). Survival was evaluated in the periods 2013-2017 and 2018-2022.
