Article Synopsis
  • The study evaluates the effectiveness of neoadjuvant immunotherapy combined with chemotherapy in patients with localized EGFR-mutant non-small cell lung cancer (NSCLC) through a phase 2 trial involving 18 participants.
  • Interim results show that while many patients had positive radiological responses, only 44% reached major pathological response, and there were no cases of complete response.
  • The research indicates that certain T cell populations are linked to resistance against immunotherapy and suggests that monitoring circulating tumor DNA (ctDNA) could help identify patients less likely to respond to such treatments.

Aberrant metabolic disorders and significant glycolytic alterations in tumor tissues and cells are hallmarks of breast cancer (BC) progression. This study aims to elucidate the key biomarkers and pathways mediating abnormal glycolysis in breast cancer using bioinformatics analysis. Differential genes expression analysis, gene ontology analysis, Kyoto encyclopedia of genes and genomes analysis, gene set enrichment analyses, and correlation analysis were performed to explore the expression and prognostic implications of glycolysis-related genes.

Background Context: Secondary spinal arachnoid cysts have rarely been reported but present significant challenges for management. These cysts could be anteriorly located with long rostral-caudal extensions and many are related to arachnoiditis, leading to difficult-to-treat disorders. Thus far, due to the scarcity of reports, the features of the disease and the optimal therapeutic strategies remain unclear.

Introduction: Dandy-Walker complex and pleomorphic xanthoastrocytomas are both rare disease entities that typically manifest early in life and are associated with congenital etiological factors. Dandy-Walker complex is a cerebellar malformation associated with a series of anatomical changes. The disease onset is usually at birth or during infancy.

Background: Meningeal melanocytoma is a rare disease that originates from leptomeningeal melanocytes in the central nervous system. Meningeal melanocytoma is generally considered benign, and has a good prognosis following complete surgical resection. Reports of the malignant transformation and spread of these tumors are scarce.

Article Synopsis
  • - The study focuses on creating an efficient and cost-effective way to produce N-acetyl-D-glucosamine (GlcNAc) using shellfish waste, which is abundant and sustainable.
  • - Researchers developed a mutant strain (C81) of Chitinolyticbacter meiyuanensis that exhibited significantly higher chitinase activity (85% improvement) and enhanced antioxidant properties compared to the original strain.
  • - Using a continuous fermentation process, the mutant successfully converted crayfish shell powder into GlcNAc, achieving an impressive yield of 4.2 g/L, demonstrating its potential for bioconversion in an aqueous-organic system.

Objective: To investigate the correlation between neonatal and maternal vitamin D levels.

Methods: From June 1 to July 10, 2015, umbilical venous blood samples were collected from 102 full-term single neonates, and venous blood samples were collected from their mothers. Ultra-performance liquid chromatography with isotope dilution was applied to measure the serum 25(OH)D level.

Article Synopsis
  • - The study aimed to identify risk factors for colonization by Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) in neonates in the NICU, using a case-control design with 9 colonized patients and matched controls.
  • - Univariable analysis identified 11 factors linked to KPC-Kp colonization, but multivariable analysis highlighted that using carbapenems for more than 4 days significantly increased the risk (OR=18.7, P=0.01).
  • - The findings emphasize the need for precautions like contact isolation and careful antibiotic use to minimize KPC-Kp colonization in vulnerable neonates.

Objective: To compare the feeding pattern of preterm infants between two hospitals in China and the United States.

Methods: A retrospective cohort study was conducted. Infants <32 weeks were enrolled from Cincinnati Children's Hospital Center Cincinnati University Hospital (CCHMC group) between January 2011 and January 2012 and Peking Union Medical College Hospital (PUMCH group) between January 2011 and May 2012.

Objective: To study the dynamic changes in macronutrients and energy in human milk from mothers of premature infants.

Methods: A total of 339 human milk samples were collected from 170 women who delivered preterm or full-term infants in the Department of Obstetrics and Gynecology, Peking Union Medical College Hospital between November 2012 and January 2014. Macronutrients (proteins, fats and carbohydrates and energy were measured using a MIRIS human milk analyzer and compared between groups.

The Global Consensus for Feeding the Preterm Infant was published in the Journal of Pediatrics 3 supplement, 2013. The content of the consensus includes recommended nutrient intake for different gestational age preterm infants, identifying appropriate growth curves, the use of breast milk, nutritional recommendations for the late-preterm infant and the preterm infant after hospital discharge, nutritional requirements and feeding recommendations for small gestation age infants, reconsideration of the importance of vitamin A and vitamin D for immature infants, recommendations for immunonutrients, and the association of feeding of preterm infants with later metabolic and cardiovascular outcomes. The main characteristics of the consensus: (1) aimed to improve prognosis; (2) individualized nutritional strategy based on gestational ages; (3) coexistence of consensus and controversy in feeding of preterm infants.

Objective: To retrospectively characterize clinical features of preterm infants born to mothers with systemic lupus erythematosus (SLE).

Methods: Clinical data of preterm infants born to mothers with SLE in Peking Union Medical College Hospital over a period of more than 10 years (2000-2012) and preterm babies born to mothers without SLE in the same hospital and during the same time period were collected. Preterm-associated complications in the two groups of babies were comparatively analyzed.

Background: Seventeen million births occur in China each year. Neonatal mortality is the leading cause of under 5-year-old child deaths, and intrapartum-related injury accounts for much of mental retardation in young children. The Chinese Ministry of Health sought to improve infant and child survival through a nationwide initiative to have at least one person trained in neonatal resuscitation at every birth.
