Background: Diagnosing and predicting neonatal sepsis is challenging because of its nonspecific symptoms, lack of diagnostic criteria consensus, and absence of early, sensitive, and specific diagnostic laboratory tests.

Purpose: To evaluate the diagnostic and prognostic potential of adrenomedullin (ADM), interleukin-6 (IL-6), and C-reactive protein (CRP) in late-onset neonatal sepsis (LOS).

Methods: We studied 53 neonates with culture-proven LOS by sampling at admission and on antibiotic treatment days 3 and 7.

Background: Lower respiratory tract infection (LRTI) is a leading cause of morbidity and mortality among children globally. Copeptin, released by the pituitary gland, serves as a biomarker for various conditions and, as a neuroendocrine stress hormone, is useful in acute conditions. This study aimed to determine the role of copeptin levels in LRTI in children and whether it can reliably predict pneumonia severity.

Photodynamic implants are an increasingly popular minimally invasive option for the surgical treatment of metastatic bone disease. Following surgery, adjuvant radiation therapy (RT) is frequently administered to achieve better disease control and improve patient quality of life, but the role of RT in implant failures associated with photodynamic implants remains unclear. The aim of this study is to determine if the therapeutic RT range of 10-50 Gy affects the biomechanical properties of photodynamic implants.

Introduction: Despite the implementation of numerous preventive measures in recent years, the persistent challenge of periprosthetic infections remains. Among the various strategies, metallic modification of implants, particularly with silver, has emerged as a promising avenue. Silver's antimicrobial properties, coupled with its low human toxicity, render it an appealing option.

Article Synopsis
  • Antarctica is facing antibiotic resistance challenges due to human activities, which threatens its traditionally untouched environment.
  • The CAS19 strain, identified as Pseudomonas migulae, was isolated from Ardley Island's lake water and showed notable characteristics including growth in varying temperatures and pH levels, along with specific enzymatic activities.
  • This strain demonstrated resistance to multiple antibiotics and heavy metals, revealing a significant increase in resistance-related gene expressions when exposed to antibiotics, highlighting potential concerns about human impact on microbial ecosystems in Antarctica.

Organohydrogels (OHGs) are intriguing materials due to their unique composition of both hydrophilic and hydrophobic domains. This antagonistic nature endows the OHGs with several remarkable properties, making them highly versatile for various applications. We present here a simple and inexpensive approach to fabricate silk fibroin (SF)-based OHGs with multistage switching mechanics and viscoelasticity.

  • This study analyzed 331 patients with primary brain abscesses (PBAs) from 39 centers in 16 countries, focusing on infection causes, risk factors, and mortality outcomes over a 12-year period.
  • Study results showed that the majority of patients were middle-aged men (average age 46.8), with symptoms like headaches and fever; Gram-positive cocci were the most common pathogens.
  • Key factors influencing mortality at 42 days included intravenous drug use and malignancy, while factors affecting 180-day mortality included temporal lobe involvement and the presence of unidentified bacteria.

Promoters are key genetic elements in the initiation and regulation of gene expression. A limited number of natural promoters has been described for the control of gene expression in synthetic biology applications. Therefore, synthetic promoters have been developed to fine-tune the transcription for the desired amount of gene product.

This study investigates the automated detection of enchondromas, benign cartilage tumors, from x-ray images using deep learning techniques. Enchondromas pose diagnostic challenges due to their potential for malignant transformation and overlapping radiographic features with other conditions. Leveraging a data set comprising 1645 x-ray images from 1173 patients, a deep-learning model implemented with Detectron2 achieved an accuracy of 0.

Background: Bevacizumab-based chemotherapies are commonly administered in the treatment of patients diagnosed with epithelial ovarian cancer (EOC). The primary aim of this study was to assess the factors that predict the objective response to bevacizumab-based therapies in cases of advanced and recurrent EOC.

Methods: The retrospective data of 264 patients with EOC from the current study were collected between 2009 and 2022 at our clinic.

In oncologic patients, optimal postoperative wound healing is crucial for the maintenance of systemic therapies and improved survival. Although several risk factors for postoperative wound complications have been identified, the clinical effect of new antineoplastic agents on wound healing remains uncertain. The available literature on the effect of antineoplastic agents in wound healing is complex to analyze because of other confounding risk factors such as radiation therapy and certain patient-specific variables.

Respiratory syncytial virus (RSV) is a common cause of respiratory infections. It is responsible for more than half of lower respiratory tract infections in infants requiring hospitalization. This study aimed to investigate the correlation between the fibrinogen-albumin ratio (FAR) and the severity of RSV infection and to compare its effectiveness with the neutrophil-lymphocyte ratio (NLR).

Objective: Chronic inflammation is considered to be of key importance in the pathogenesis of polycystic ovarian syndrome (PCOS). Ganoderma lucidum polysaccharide (GLP) and Hypericum perforatum (HP) have been reported to have anti-inflammatory and antioxidant activities. We studied the effects of these agents on ovarian tissue in a rat model of experimental PCOS.

Background: Distal humerus replacement (DHR) is a modular endoprosthesis mainly used for bone reconstruction after resection of primary or metastatic bone lesions. Studies on DHR failure rates and postoperative functional outcomes are scarce. We sought to assess implant survival, modes of failure, and functional outcomes in patients undergoing DHR for oncologic indications.

Article Synopsis
  • - Fluorescence-guided surgery (FGS) is a promising technique to determine surgical margins during operations for bone and soft tissue sarcomas, but its use in orthopaedic oncology is still limited.
  • - A review of existing studies showed mixed results for FGS’s effectiveness, with sensitivity ranging from 22.2% to 100% and specificity from 9.38% to 100%, highlighting the varied performance metrics due to differences in study quality.
  • - Overall, while FGS is a viable option for assessing tumor margins, the inconsistency in findings and performance metrics suggests a need for more rigorous studies to improve its reliability in clinical practice.

Cryogelation is a powerful technique for producing macroporous hydrogels called cryogels. Although cryogelation reactions and cryogels were discovered more than 70 years ago, they attracted significant interest only in the last 20 years mainly due to their extraordinary properties compared to the classical hydrogels such as a high toughness, almost complete squeezability, a mechanically stable porous structure with honeycomb arrangement, poroelasticity, and fast responsivity against external stimuli. In this mini review, general properties of cryogelation systems including the cryoconcentration phenomenon responsible for the unique properties of the cryogels are discussed.
