Bias undermines evidence-based decision making. To counter this, surgeons must be aware of biases that may influence studies' reported outcomes. Lumbar spinal stenosis often requires operative intervention, with multiple available surgical strategies. Our aim was to assess the role that country of origin plays in published surgical outcomes for lumbar spinal stenosis.

We performed a search strategy of MEDLINE and EMBASE for all English language primary research papers evaluating operative interventions for lumbar spinal stenosis during the years 2010-2019 inclusive. Small case series and meta-analyses were excluded. Papers were assessed for outcome positivity and country of origin. Data analysis was conducted using GraphPad Prism statistical software.

A total of 487 papers met the inclusion criteria. Of these, 419 (86%) reported positive outcomes. Asian studies were the most likely to report positive outcomes, at 93% (220 of 236), followed by US studies at 89% (98 of 110). European studies had the lowest positive publication rate at 69% (84 of 121). Region of origin was an independent predictor of positive study outcome on multivariable analysis when controlling for different study designs and healthcare systems.

There is an association between country of origin and positive reported outcome in studies evaluating interventions for lumbar spinal stenosis. Clinicians should consider this when making management decisions based on published evidence.

To investigate radiological risk factors for recurrent lumbar disc herniation (rLDH) after percutaneous transforaminal endoscopic discectomy (PTED).

Patients who underwent PTED due to a single-level L4-L5 or L5-S1 disc herniation from January 2013 to May 2019 were enrolled in this study. A matched case-control design was carried out in a single institution. Cases were defined as those who developed rLDH, and controls were matched from those patients without rLDH according to corresponding clinical characteristics. The radiological parameters were compared between two groups. The radiological risk factors for rLDH after PTED were identified by univariate and multivariate logistic regression analysis.

A total of 2186 patients who underwent PTED at L4-L5 or L5-S1 level were enrolled in this study. Sixty-eight patients were diagnosed with rLDH, and 136 patients were selected from the remaining 2118 nonrecurrent patients as matched controls. Univariate analysis demonstrated that herniation type (P = 0.009), surgical-level disc degeneration (P < 0.001), adjacent-level disc degeneration (P = 0.017), disc height index (DHI) (P = 0.003), and sagittal range of motion (sROM) (P < 0.001) were significantly related to rLDH. Multiple logistic regression analysis showed that low grade of surgical-level disc degeneration (P < 0.001), senior grade of adjacent-level disc degeneration (P < 0.001), a high DHI (P = 0.012), and a large sROM (P < 0.001) were the radiological independent risk factors.

This study showed that low grade of surgical-level disc degeneration, senior grade of adjacent-level disc degeneration, a high DHI, and a large sROM were the radiological independent risk factors for rLDH after PTED.

Gastric cancer (GC) is a leading cause of cancer morbidity and mortality worldwide. This is due to the heterogeneous features of GC, which consist of a diverse molecular phenotype. Epstein-Barr virus (EBV)-positive GC and microsatellite instability (MSI)-high GC encompass similar epigenetic traits, including high levels of DNA methylation in CpG islands; however, EBV-positive and MSI-high GCs are mutually exclusive. We aimed to elucidate the underlying mechanism of this exclusivity.

We knocked out MLH1 in EBV-positive GC cell lines SNU-719 and NCC24 via CRISPR-Cas9, and evaluated the modified cellular properties in vitro and in vivo. The MSI status of each cell line was screened with two marker capillary electrophoresis, and further diagnosed with five marker capillary electrophoresis and parallel sequencing using 21 markers.

Initial evaluation showed that cell growth, migration, invasion, and MSI status were not affected by MLH1 silencing. However, with prolonged passage, GC cell lines gradually gained MSI and NCC24 cells were transformed to EBV-positive/MSI-high GC cells after 12months. Furthermore, MLH1 silencing reduced tumor stemness in SNU-719 and NCC24 regardless of the MSI status in vitro and in vivo.

Our findings suggest that EBV-positivity and MSI-high status are mutually exclusive due to the immediate disadvantage in tumor stemness when MLH1 is silenced, whereas the establishment of MSI-high status in EBV-positive GCs required a longer period.

The tobacco industry has been reported to employ sex-specific marketing strategies, which include different types of tobacco packaging, publicity, as well as price strategies. We examined whether characteristics associated with the purchase of more expensive cigarette brands varied by sex, in the context of the introduction of plain tobacco packaging and the strengthening of tobacco control policies in France.

Our study population consists of 1380 regular smokers of manufactured cigarettes from the DePICT study, a nation-wide two-wave survey of French adults aged 18-64years. Participants were interviewed by telephone in 2016 and 2017. Factors associated with the use of more vs. less expensive cigarette brands were determined by multivariable logistic regression stratified by sex.

Several sex-specific factors were associated with the purchase of more expensive cigarette brands. In women, those factors included higher education, cannabis use, and no use of roll-your-own tobacco. While in men purchase of more expensive cigarette brands was linked to younger age, being born outside of France, living with a non-smoker, and attachment to the cigarette brand.

Factors which predict tobacco purchase patterns are different in women and men, highlighting the need for sex-specific tobacco control initiatives to counter the tobacco industry's gendered marketing.

During the past decade, considerable progress has been made towards our understanding of the cellular and physiological functions of TMEM106B. TMEM106B regulates many aspects of lysosomal function, including lysosomal pH, lysosome movement, and lysosome exocytosis. Both an increase and decrease in TMEM106B levels result in lysosomal abnormalities. In mouse models, TMEM106B deficiency leads to lysosome trafficking and myelination defects and FTLD related pathology. In humans, alterations in TMEM106B levels or function are intimately linked to neuronal proportions, brain aging, and brain disorders. Further elucidation of the physiological function of TMEM106B and changes in TMEM106B under pathological conditions will facilitate therapeutic development to treat brain disorders associated with TMEM106B.
The primary aim of this study was to compare clinical outcomes in patients with associated both column (ABC) acetabular fractures with fracture of the posterior wall (PW), in which the PW underwent reduction and fragment-specific fixation versus those that were treated with column fixation alone. Secondary aims were to assess PW fracture incidence and morphology, as well as to compare radiographic outcomes including fracture healing and interval displacement of the PW in those that did and did not undergo fragment-specific fixation of the PW.

This was a retrospective series of ABC acetabular fractures treated at a single Level I trauma center. Separate fractures of the PW were identified, and associated features were assessed. Associated both column fractures that underwent reduction and fragment-specific fixation of the PW where then compared to ABC fractures with PW involvement that underwent column reconstruction alone. Radiographic and clinical outcomes were compared.

Fractures of the PW occurred inBC patterns are frequently large-sized fragments that involve the acetabular roof and are rendered stable after reconstruction of the columns.
The malignant transformation of normal bladder cells (SV-HUC-1) was induced by arsenite to explore the possible mechanism of circRNA-100284 influencing bladder cancer cell proliferation.

Normal bladder SV-HUC-1 cells were cultured with 2μM arsenite to induce malignant transformation. After 0, 3, 6, 12, and 24h of culture, the expression level of circRNA-100284 in cells was detected by quantitative real-time PCR. Western blotting assays were used to detect the expression levels of EZH2 and cyclin-D1 proteins in cells treated with different media. Cell cycle was analyzed by flow cytometry. In addition, through cell transfection and CCK-8 experiments, the effect and mechanism of circRNA-100284 targeting microRNA-217 on proliferation was determined. The interaction between HSP70 methylation and Aurora-B was determined by Western blotting and immunoprecipitation experiments.

With prolonged contact time with arsenite, the expression level of circRNA-100284 in cells increased continuously (P < 0.05). Western blotting assays showed that the expression levels of EZH2 and cyclin-D1 proteins in arsenite-transformed cells increased. Flow cytometry and CCK-8 showed that circRNA-100284 accelerated cell cycle transition and cell proliferation through miR-217. Finally, after culturing human bladder cancer T24 cells, combined with immunoprecipitation and in vitro kinase experiments, it was found that K561- dimethyl HSP70 activated Aurora-B, thus promoting the proliferation of bladder cancer cells.

CircRNA-100284 activates aurora kinase B by inducing methylation of HSP70 via microRNA-217 to promote the proliferation of bladder cancer cells.

In particular, the arousal reduction hypothesis states that yawning signals to others that the actor is experiencing a down regulation of arousal and vigilance. If true, seeing another individual yawn might enhance the vigilance of observers to compensate for the reduced mental processing of the yawner. This was tested in humans by assessing how exposure to yawning stimuli alters performance on visual search tasks for detecting snakes (a threatening stimulus) and frogs (a neutral stimulus). In a repeated-measures design, 38 participants completed these tasks separately after viewing yawning and control videos. Eye-tracking was used to measure detection latency and distractor fixation frequency. Replicating previous evolutionary-based research, snakes were detected more rapidly than frogs across trials. Selleck Mizagliflozin Moreover, consistent with the view that yawning holds a distinct signaling function, there were significant interactions for both detection latency and distractor fixation frequency showing that vigilance was selectively enhanced following exposure to yawns.
