Nephropathy is a common health issue associated with type 2 diabetes mellitus (T2DM). Treatment of diabetic nephropathy (DN) in an early stage can effectively inhibit its progression. Albuminuria is the currently accepted marker for detection of DN. ⋯ AUCs of periostin were higher than that for cyclophilin A with a significant AUC difference (p=0.022) in overt DN stage. Periostin and cyclophilin A could be regarded as a potential urinary biomarker for early prediction of DN. Periostin exhibits a higher diagnostic accuracy than urinary cyclophilin A specifically in overt DN stage.

Infants requiring hospitalization due to a viral lower respiratory tract infection (LRTI) have a high risk of developing recurrent respiratory illnesses in early life and asthma beyond childhood. Notably, all validated clinical scales for viral LRTI have focused on predicting acute severity instead of recurrence. We present a novel clinical approach combining individual risk factors with bedside clinical parameters to predict recurrence after viral LRTI hospitalization in young children. ⋯ After the first hospitalization, the strongest predictors of subsequent episodes were wheezing (OR=5.62; 95% CI 1.03 to 30.62; p=0.04) and family history of asthma (OR=5.39; 95% CI 1.04 to 27.96; p=0.04). We found that integrating individual risk factors (eg, prematurity or family history of asthma) with bedside clinical assessment (eg, wheezing, subcostal retractions or hypoxemia) can predict the risk of recurrence after viral LRTI hospitalization in infants. This strategy may enable clinically oriented subsetting of infants with viral LRTI based on individual predictors for recurrent respiratory illnesses during early life.

The present study aimed to investigate the influence of several important preanalytical factors (storage period of the tumor block, maximal diameter of the tumor circled area, tumor volume and tumor fraction) on the isolated DNA from formalin-fixed paraffin-embedded (FFPE) tissues in a series of thyroid carcinomas. ⋯ The maximal diameter of the tumor circled area, tumor volume and tumor fraction are important morphological factors that correlate with the DNA concentration and should be carefully assessed in routine practice prior to performing DNA isolation from FFPE tissues.

Gastric cancer (GC) is a commonly diagnosed malignancy with a high mortality rate worldwide. Despite advances in therapeutic approaches, the 5-year survival rate of patients with GC remains poor. A type of non-coding RNA, circular RNA (circRNA), has been discovered. ⋯ Real-time PCR experiments on hsa_circ_0103398 and hsa_circ_0127859 in tumors and normal tissues showed that these circRNAs were significantly upregulated in GC. High expression of hsa_circ_0103398 and hsa_circ_0127859 was closely associated with unfavorable survival time. Our findings indicated that a 5-circRNA signature might serve as a candidate prognostic biomarker of GC.

The present study aimed to analyze the methylation pattern of the MIR200 family in the colorectal tissues and peripheral blood of colorectal cancer (CRC) patients. Previous informed consent, 102 samples of colorectal tissues (tumor and adjacent normal tissues) and 40 peripheral blood samples were collected from CRC patients. Additionally, we included a reference group of 40 blood samples. ⋯ MIR200B/MIR200A/MIR429 methylation analysis discloses no differences among tissues (p>0.05). However, MIR200C/MIR141 methylation showed differences between colorectal tissues and peripheral blood of CRC patients (p<0.0001) and mainly methylated alleles were observed in peripheral blood. These findings suggest a tissue-specific methylation pattern for the MIR200C/MIR141 promoter.
