The standard of treatment for completely resected limited-stage diffuse large B cell lymphoma (DLBCL) in patients without residual lesions has not yet been established. Previously, we designed a phase II trial to evaluate the safety and efficacy of three cycles of abbreviated R-CHOP in patients with completely resected limited-stage DLBCL and reported favorable survival outcomes. We present the long-term follow-up results to taking into account the importance of delayed relapse in patients with limited-stage DLBCL. With a median follow-up duration of 62.7 months (range, 60.2-75.5 months), the 5-year OS and DFS rates were both 95.0% (95% confidence interval, 85.59-104.11%). Only one patient experienced disease progression which was confirmed at 12.3 months, and one patient with primary intestinal DLBCL developed non-small cell lung cancer 6 years after treatment. The long-term results of our data support the use of three cycles of abbreviated R-CHOP for patients with completely resected limited-stage DLBCL. The study was reviewed and approved by the review boards of the participating institutes and registered at ClinicalTrials.gov , number NCT01279902, in August 3, 2010.
Endoscopic dacryocystorhinostomy (e-DCR) is the mainstay for lacrimal sac/duct conditions. The purpose is to investigate the role of the exoscope as assisting tool in e-DCR.

Primary endpoint were symptoms resolution (epiphora/dacryocystitis) and time for surgery. Qualitative features of the exoscope were analyzed a questionnaire administered to the surgical team allowed to evaluate the perceived quality of this technology.

The exoscope is a new tool that may support e-DCR. It has comparable results on symptoms outcomes and time for surgery than classic e-DCR. This new technology was accepted by all team members and showed great teaching potential.

This study aimed to evaluate the pre- and post-operative quality-of-life of patients submitted to the resection of pituitary adenoma via endoscopic transsphenoidal.

This was a prospective study on patients submitted to endoscopic transsphenoidal pituitary surgery with the harvest of a nasoseptal flap who responded to the questionnaires FV-36 and SNOT-22 in the pre-operative and in months 1, 3 and 6 following the surgical procedure.

A total of 42 patients submitted to pituitary adenoma resection surgery via endoscopic transsphenoidal with a nasoseptal flap were recruited. In all of the physical and mental domains (SF-36) evaluated, there was an improvement in the long-term evaluation (6months), compared to the pre-operative, as well as in the site-specific evaluation (SNOT-22).

The global and site-specific questionnaires in the 6th post-operative month follow-up presented an important improvement in all the physical and mental domains evaluated, as well as in nasal function in the perception of the patients submitted to pituitary adenoma resection via endoscopic transsphenoidal, demonstrating the safety and efficiency of the procedure.

The aim of this study is to investigate the frequency and locations of residual adenoid tissue in conventional curettage adenoidectomy (CA) via transnasal endoscopic examination at the end of the operation and to determine the most appropriate technique for residual adenoid tissue removal by transoral or transnasal microdebrider usage.

Sixty-three patients aged 4-12years who were scheduled for CA were included in this randomized prospective study in a tertiary reference center. Patients who underwent CA had the endoscopic residual tissue exploration at the end of surgery. The amount and locations of residual tissue were recorded. Patients with > 20% residual tissue were divided into two groups according to randomization list for removing the residual tissue, depending on the use of transoral microdebrider (TOMD) and transnasal microdebrider (TNMD). #link# Two procedures were compared in terms of duration, bleeding, pain, post-anesthesia care unit (PACU) transfer time, and complications.

Residual tissue was detected in 38 patients (60.2%). The most common location of residual tissue was peritubal area (41.3%). The TOMD group had lower surgical duration, blood loss, pain scores and shorter PACU transfer time (p = 0.001, p = 0.002, p˂0.001, and p = 0.006, respectively).

Endoscopic exploration at the end of CA should be considered to avoid residual tissue retention. Furthermore, if residual tissue is present, the use of TOMD is easier, faster, and associated with lower morbidity than the use of TNMD.

However, the relationship between BMI and BMD varies according to different studies. Using SNPs strongly associated with BMI in 336,107 individuals, we conducted a two-sample Mendelian randomization study to identify whether and to what extent BMD at different skeletal sites was affected by BMI. A power calculation was also performed. We found that BMI may causally increase lumbar BMD (β 0.087; 95% CI 0.025 to 0.149; P = 0.006) and heel calcaneus BMD (β 0.120; 95% CI 0.082 to 0.157; P = 1 × 10-7). The associations of BMI with forearm and femoral neck BMD were not statistically significant. Our study suggested that higher BMI plays a causal role in increasing BMD and the effects are similar across the skeleton. BMI was causally and positively associated with lumbar and heel calcaneus BMD. However, no statistically significant effects were observed for BMI on femoral neck or forearm BMD.Rapid advancements in the area of lung cancer therapy were determined by the discovery of molecular markers and the possibility of their therapeutic exploitation. Today's lung cancer diagnosis places high demands on pathologists. In the majority of cases, small tissue samples must suffice for diagnosis and testing of all relevant biomarkers. The minimum panel required for advanced non-small-cell lung carcinoma (NSCLC) with nonsquamous histology includes testing of EGFR, BRAF, ALK, ROS1, and PD-L1-expression. So far, only PD-L1-IHC (immunohistochemistry, IHC) is required for squamous cell carcinoma. If possible, newer biomarkers such as RET, MET, HER2, NTRK, and KRAS should be integrated in test panels. Fluorescence in situ hybridization (FISH) is a well-established molecular method for the detection of chromosomal aberrations, such as ALK-, ROS1-, and RET- translocations and amplifications, such as Her2/neu or MET. The relevance of MET-FISH for the detection of amplifications in the first-line setting is controversial, but of high importance in the recurrent setting. All equivocal or discrepant results should be validated using orthogonal methods. IHC is a suitable, thoroughly validated method for ALK and ROS1 aberration detection with the advantage of quick and cost-efficient test results and tissue conservation. All other translocations, or discrepancy between IHC and FISH, require a sequencing-based confirmation procedure. BRM/BRG1 ATP Inhibitor-1 of NTRK fusions, and high sensitivity of NTRK-IHC, suggest using IHC as a prescreening tool with subsequent sequencing-based analysis for IHC positive cases.Prematurity is a prototype of biological risk that could affect the late neurocognitive outcome; however, the condition itself remains a non-specific marker. This longitudinal 6-year study aimed to evaluate the prognostic role of neonatal spectral EEG in premature infants without neurological complications. link2 The study cohort was 26 children born 23-34 gestational ages; all neonates underwent multichannel EEG recordings at 35 weeks post-conception. EEG data were transformed into the frequency domain and divided into delta (0.5-4 Hz), theta (5-7 Hz), alpha (8-13 Hz), and beta (14-20 Hz) frequency bands. At 6 years, a neuropsychological and behavioral evaluation was performed. Correlations between spectral bands and neuropsychological assessments were performed with a conservative and robust Bayesian correlation model using weakly informative priors. The correlation of neuropsychological tasks to spectral frequency bands highlighted a significant association with visual and auditory attention tests. The performance on the same tests appears to be mainly impaired.Conclusions We found that spectral EEG frequencies are independent predictors of performance in attention tasks. We hypothesized that spectral EEG might reflect early circuitries' imbalance in the reticular ascending system and cumulative effect on ongoing development, pointing to the importance of early prognostic instruments. What is Known • Prematurity is a non-specific marker of late neurocognitive risk. • Precise prognostic instruments are lacking, mostly in patients with low-grade conditions. What is New • Longitudinal long-term studies are scarce but crucial for the inferential attributive process. • Spectral EEG frequencies are independent predictors of performance in attention tasks.Wastewater (WW) irrigation to agricultural soils is one of the most economical and effective water-saving strategies. The effects of WW irrigation on soil microbial communities have gained increasing focus as these effects are not well understood. In this study, the effects of WW and groundwater (GW) irrigation on microbial diversity and structure were compared using the high-throughput sequencing analysis of 16S rDNA amplicons. Soil samples irrigated by WW for several decades and maize soil (loamy) samples irrigated by GW were collected from Luancheng Town, Shijiazhuang City, China. Compared to the GW groups, WW groups exhibited non-significant soil bacterial community abundance at the 0-20 and 20-40 cm depths. WW irrigation significantly altered the bacterial community composition and structures compared to GW irrigation. The relative abundance of Proteobacteria and Firmicutes increased in WW irrigated soil, while Actinobacteria decreased. Moreover, 14 significantly abundant biomarkers from Proteobacteria and Firmicutes that corresponded with WW irrigation were identified. Additionally, WW irrigation enriched some KEGG pathways that corresponded with metabolism and human diseases. link3 The physical and chemical properties of WW irrigated soil may shape the compositions and structures of soil bacterial communities. The findings of this study illuminated the effects of wastewater irrigation on microbial characteristics, which is important for estimating the effects of long-term wastewater irrigation on soil environmental health.
