Humour in the classroom: student views of a humourous teacher

Teachers vary in their approach to humour in the classroom. Three possible approaches include the teacher who is serious and disciplined, the second who is humourous and encourages laughter, or finally the teacher who is humourous through sarcasm. In which scenario would students prefer to be a participant? Through an interview process, this study attempts to answer whether students prefer a humourous or non-humourous teacher. Three students were presented with scenarios describing the classroom of the three possible teaching approaches and were asked to identify which teacher they would prefer. The students also rated a list of teacher traits that included humour. All three stated a preference for the classroom of the humourous teacher, and a sense of humour ranked in the top five of all the lists. No student was comfortable with humour, though, without respect. The students agreed that when a classroom teacher uses humour in a respectful manner, the learning atmosphere is enhanced.
Hemangiomas of the tongue and the oral cavity in a myotonic dystrophy type 1 patient

Rationale: Myotonic dystrophy type 1 (DM1) is an autosomal dominant disease caused by a cytosine, guanine, thymine (CTG) trinucleotide repeat expansion in the non-coding region of dystrophia myotonica protein kinase gene, causing a multisystem involvement. To date, few studies have been performed to evaluate skin features in DM1 patients, but none reported on the possible association between the disease and tongue hemangiomas. Patients concerns: We report a case of a 63-year-old woman affected by DM1 and presenting, at the intraoral examination, several swelling and buish lesions occurring on buccal and palatal mucosa, and in the anterior two-thirds and margins of the tongue. Diagnosis: Multiple tongue hemangiomas in DM1 patient. Interventions: Color Doppler ultrasound revealed hypoechoic lesions with intermittent color picking suggestive of vascular lesion. Surgical excision was performed under general anesthesia. Histopathological examination was compatible with the diagnosis of cavernous hemangiomas. Outcomes: At 6 months follow-up, a part from the cosmetic deformity, patient's hemangiomas did not bleed, but caused functional problems with speaking, mastication, and deglutition, in addition to the same symptoms induced by DM1. Lessons: This case may add new details to better characterize the DM1 phenotype, suggesting that even tongue hemangiomas may be part of the DM1 multisystem involvement.
A Sensorimotor Pathway via Higher-Order Thalamus

We now know that sensory processing in cortex occurs not only via direct communication between primary to secondary areas, but also via their parallel cortico-thalamo-cortical (i.e., trans-thalamic) pathways. Both corticocortical and trans-thalamic pathways mainly signal through glutamatergic class 1 (driver) synapses, which have robust and efficient synaptic dynamics suited for the transfer of information such as receptive field properties, suggesting the importance of class 1 synapses in feedforward, hierarchical processing. However, such a parallel arrangement has only been identified in sensory cortical areas: visual, somatosensory, and auditory. To test the generality of trans-thalamic pathways, we sought to establish its presence beyond purely sensory cortices to determine whether there is a trans-thalamic pathway parallel to the established primary somatosensory (S1) to primary motor (M1) pathway. We used trans-synaptic viral tracing, optogenetics in slice preparations, and bouton size analysis in the mouse (both sexes) to document that a circuit exists from layer 5 of S1 through the posterior medial nucleus of the thalamus to M1 with glutamatergic class 1 properties. This represents a hitherto unknown, robust sensorimotor linkage and suggests that the arrangement of parallel direct and trans-thalamic corticocortical circuits may be present as a general feature of cortical functioning. SIGNIFICANCE STATEMENT During sensory processing, feedforward pathways carry information such as receptive field properties via glutamatergic class 1 synapses, which have robust and efficient synaptic dynamics. As expected, class 1 synapses subserve the feedforward projection from primary to secondary sensory cortex, but also a route through specific higher-order thalamic nuclei, creating a parallel feedforward trans-thalamic pathway. We now extend the concept of cortical areas being connected via parallel, direct, and trans-thalamic circuits from purely sensory cortices to a sensorimotor cortical circuit (i.e., primary sensory cortex to primary motor cortex). This suggests a generalized arrangement for corticocortical communication.
Khushleen@IECSIL-FIRE-2018: Indic Language Named Entity Recognition using Bidirectional LSTMs with Subword Information

Named Entity Recognition generally requires large amount of tagged corpus to build a high performing system. The representation has always been a bottleneck in NERs success. The NER subtask by IECSIL had enough data for algorithms to learn semantic representation as well as apply deep learning models. The current work uses a subword aware word representation for generating representations. These embeddings are further used with a bidirectional LSTM for building an NER system. The system performed well for all the Indian languages and stood among top three submissions.
Effect of computer navigation-assisted minimally invasive direct lateral interbody fusion in the treatment of patients with lumbar tuberculosis

Abstract The benefits of navigation-assisted technologies are not entirely understood. Therefore, this study aimed to examine the outcomes of patients with lumbar tuberculosis who received computer navigation-assisted minimally invasive direct lateral interbody fusion (DLIF). This was a retrospective study of 33 patients with lumbar tuberculosis who underwent minimally invasive DLIF at the Department of Spine and Orthopedics of Guigang People's Hospital (Guangxi, China) between January 2015 and December 2016. The patients were pathologically diagnosed as lumbar tuberculosis and grouped into the navigation-assisted fluoroscopy (NAV; n = 18) and non-navigation-assisted fluoroscopy (non-NAV; n = 15) groups. X-ray exposure and operation times were assessed in all patients. All surgical procedures were successfully completed. No case was converted into open surgery. The NAV group had longer surgical preparation time but shorter operation time compared with the non-NAV group (both P <.01). Total operation time showed no significant difference between the 2 groups (P = .1). The time of radiation exposure in the non-NAV group was longer compared with that of the NAV group (53.2 ± 9.9 vs 13.5 ± 2.6 s; P <.01). There were no significant differences regarding intraoperative blood loss, postoperative drainage volume, length of hospital stay, bone fusion and complications between the 2 groups (all P >.05). Computer navigation-assisted minimally invasive DLIF could significantly reduce intraoperative radiation exposure, with no increase in total operation time.
Managing a moral identity in debt advice conversations

Previous research has found that stigma can be a barrier to service use but there has been little work examining actual service encounters involving members of stigmatized groups. One such group are those with problematic or unmanageable debts. Providing advice to members of this group is likely to be particularly difficult due to the stigma associated with being in debt. Using conversation analysis and discursive psychology, this study examines 12 telephone advice conversations between debt advisors and individuals in debt. Both clients and advisors oriented to the negative moral implications of indebtedness and typically worked collaboratively to manage these issues. Clients often claimed a moral disposition as a way to disclaim any unwanted associations with debt, but could find it difficult to reconcile this with an insolvency agreement. Moreover, the institutional requirements of the interaction could disrupt the collaborative management of stigma and advisors could manage the subsequent resistance from clients in either client‐centred or institution‐centred ways. The findings suggest that the products offered by debt advice agencies, as well as the manner in which they are offered to clients, can either help or hinder debtors negotiate the stigma‐related barriers to service engagement.
Comparison of the diagnostic efficiency for local recurrence of rectal cancer using CT, MRI, PET and PET-CT

Background: The risk of local recurrence (LR) continues to threat patients with rectal cancer after surgery or chemoradiotherapy. The main reason is that there is frequently extensive scarring and reactive changes after radiotherapy and resection. Thus, the diagnosis of LR can be challenging. There are different imaging modalities that have been used in the follow-up of rectal cancer, including computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and positron emission tomography-computed tomography (PET-CT) in clinical practice. Methods: We will systematically search PubMed, EMBASE, the Cochrane Library, and Chinese Biomedical Literature Database for diagnostic trials using CT, MRI, PET, and PET-CT to detect LR of rectal cancer in April, 2018. Two review authors will independently screen titles and abstracts for relevance, assess full texts for inclusion, and carry out data extraction and methodological quality assessment using the QUADAS-2 tool. We will use bivariate meta-analysis to estimate summary sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio of CT, MRI, PET, and PET-CT, as well as different sequences of MRI. For each index test, estimates of sensitivity and specificity from each study will be plotted in summary receive operating curve space and forest plots will be constructed for visual examination of variation in test accuracy. We will perform meta-analyses using the hierarchical summary receiver-operating characteristic model to produce summary estimates of sensitivity and specificity. Then, head-to-head and indirect comparison meta-analyses will be carried out. Discussion: This review will help determine the diagnostic accuracy of CT, MRI, PET, and PET-CT for the diagnosis of patients with LR of rectal cancer. Ethics and dissemination: Ethics approval and patient consent are not required, as this study is a systematic review. PROSPERO registration number: CRD42018104918.
Gene Expression Programs of Human Smooth Muscle Cells: Tissue-Specific Differentiation and Prognostic Significance in Breast Cancers

Smooth muscle is present in a wide variety of anatomical locations, such as blood vessels, various visceral organs, and hair follicles. Contraction of smooth muscle is central to functions as diverse as peristalsis, urination, respiration, and the maintenance of vascular tone. Despite the varied physiological roles of smooth muscle cells (SMCs), we possess only a limited knowledge of the heterogeneity underlying their functional and anatomic specializations. As a step toward understanding the intrinsic differences between SMCs from different anatomical locations, we used DNA microarrays to profile global gene expression patterns in 36 SMC samples from various tissues after propagation under defined conditions in cell culture. Significant variations were found between the cells isolated from blood vessels, bronchi, and visceral organs. Furthermore, pervasive differences were noted within the visceral organ subgroups that appear to reflect the distinct molecular pathways essential for organogenesis as well as those involved in organ-specific contractile and physiological properties. Finally, we sought to understand how this diversity may contribute to SMC-involving pathology. We found that a gene expression signature of the responses of vascular SMCs to serum exposure is associated with a significantly poorer prognosis in human cancers, potentially linking vascular injury response to tumor progression.
Campylobacter coli From Retail Liver and Meat Products Is More Aerotolerant Than Campylobacter jejuni

Aerotolerance in the microaerophilic species Campylobacter was previously reported and could increase bacterial survival and transmission in foods during stressful processing and storage conditions. In this study, 167 Campylobacter isolates (76 C. jejuni and 91 C. coli) were screened for aerotolerance; these strains were previously isolated from retail chicken meat, chicken livers, chicken gizzards, turkey, pork, and beef liver samples. Bacterial cultures were incubated aerobically in Mueller Hinton broth with agitation and viable cell counts were taken at 0, 6, 12, and 24 h. Approximately 47% of the screened Campylobacter isolates were aerotolerant (viable after a 12-h aerobic incubation period), whereas 24% were hyper-aerotolerant (viable after a 24-h aerobic incubation). A greater prevalence of aerotolerant strains (80%) was found among C. coli isolates as compared to C. jejuni isolates (6%). Differences in the oxidative stress response related genes were detected among C. jejuni and C. coli isolates when comparative genomics was used to analyze 17 Whole Genome Sequenced (WGS) strains from our laboratory. Genes encoding putative transcriptional regulator proteins and a catalase-like heme binding protein were found in C. coli genomes, but were absent in the genomes of C. jejuni. PCR screening showed the presence of a catalase-like protein gene in 75% (68/91) of C. coli strains, which was absent in all tested C. jejuni strains. While about 79% (30/38) of the hyper-aerotolerant C. coli strains harbored the catalase-like protein gene, the gene was also present in a number of the aerosensitive strains. The Catalase like protein gene was found to be expressed in both aerobic and microaerobic conditions with a 2-fold higher gene expression detected in aerobic conditions for an aerosensitive strain. However, the exact function of the gene remains unclear and awaits further investigation. In conclusion, aerotolerant Campylobacter strains (especially C. coli) are prevalent in various retail meats. Further studies are needed to investigate whether the genes encoding catalase-like heme binding protein and putative transcriptional regulators in C. coli strains are involved in stress response.

Managing chronic kidney disease in diabetes patients with the latest chemical therapies

ABSTRACT Introduction: During the years, while treatment strategy for diabetes mellitus has improved, the incidence of diabetes worldwide increases continuously. Chronic kidney disease (CKD) is one of the major diabetic microvascular complications, and a primary cause leading to end-stage renal disease (ESRD). The progression to ESRD, affected by hyperglycemia and hypertension, is characterized by microalbuminuria and macroalbuminuria. With advances in understanding the pathogenesis of CKD in diabetic patients, many novel therapeutic targets have been proposed, and the corresponding agents are being developed continually to prevent the progression of CKD. Areas covered: This review focuses on those tested in phase III clinical trials for the treatment of CKD in diabetic patients, including renin-angiotensin system blockers, aldosterone antagonists, calcium channel blockers, TGF-β inhibitors, protein kinase C inhibitors, advanced glycation end products inhibitors, GLP-1 analogues, DPP-4 inhibitors, SGLT2 inhibitors, endothelin receptor antagonists, and so on. Expert commentary: The ideal control of glucose and blood pressure and healthy lifestyle are prerequisite for diabetic patients, despite the progression of CKD is inevitable. Over the last few years, several agents have been developed to delay and even reverse progression of CKD in diabetic patients.
Executive summary: guidelines and recommendations for laboratory analysis in the diagnosis and management of diabetes mellitus.

BACKGROUND Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. APPROACH An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of the evidence and the strength of the recommendations. A draft of the guidelines was posted on the Internet, and the document was modified in response to comments. The guidelines were reviewed by the joint Evidence-Based Laboratory Medicine Committee of the AACC and the National Academy of Clinical Biochemistry and were accepted after revisions by the Professional Practice Committee and subsequent approval by the Executive Committee of the American Diabetes Association. CONTENT In addition to the long-standing criteria based on measurement of venous plasma glucose, diabetes can be diagnosed by demonstrating increased hemoglobin A(1c) (Hb A(1c)) concentrations in the blood. Monitoring of glycemic control is performed by the patients measuring their own plasma or blood glucose with meters and by laboratory analysis of Hb A(1c). The potential roles of noninvasive glucose monitoring, genetic testing, and measurement of autoantibodies, urine albumin, insulin, proinsulin, C-peptide, and other analytes are addressed. SUMMARY The guidelines provide specific recommendations based on published data or derived from expert consensus. Several analytes are found to have minimal clinical value at the present time, and measurement of them is not recommended.
NEURL4 regulates the transcriptional activity of tumor suppressor protein p53 by modulating its oligomerization

p53 is a transcription factor that regulates important cellular processes related to tumor suppression, including induction of senescence, apoptosis, and DNA repair as well as the inhibition of angiogenesis and cell migration. Therefore, it is critical to understand the molecular mechanism that regulates it. p53 tetramerization is a key step in its activation process and the regulation of this oligomerization, an important control point. The E3 ubiquitin ligase HERC2 controls the p53 transcriptional activity by regulation of its oligomerization state. HERC2-interacting proteins such as the adaptor-like protein with six neuralized domains NEURL4 are also candidates to regulate p53 activity. Here, we demonstrate the existence of an interaction network between NEURL4, HERC2 and p53 proteins. We report a functional interaction between NEURL4 and p53, involving the C-terminal region of p53 and the neuralized domains 3 and 4 of NEURL4. Through this interaction, NEURL4 regulates the transcriptional activity of p53. Thus, NEURL4 depletion reduced the transcriptional activity whereas NEURL4 overexpression increased it. In both cases, p53 stability was not affected. Although NEURL4 may interact with p53 independently of the E3 ubiquitin ligase HERC2, we observed that both proteins are needed to regulate the transcriptional activity of p53. Clonogenic assays confirmed the functional relevance of this interaction observing a decrease in cell growth by NEURL4 overexpression correlated to the increase of cellular cycle inhibitor p21 by p53 activation. Under these conditions, NEURL4 activated p53 oligomerization. All these findings identify NEURL4 as a novel regulator of the p53’s signaling.
Pathologists’ diagnosis of invasive melanoma and melanocytic proliferations: observer accuracy and reproducibility study

Objective To quantify the accuracy and reproducibility of pathologists’ diagnoses of melanocytic skin lesions. Design Observer accuracy and reproducibility study. Setting 10 US states. Participants Skin biopsy cases (n=240), grouped into sets of 36 or 48. Pathologists from 10 US states were randomized to independently interpret the same set on two occasions (phases 1 and 2), at least eight months apart. Main outcome measures Pathologists’ interpretations were condensed into five classes: I (eg, nevus or mild atypia); II (eg, moderate atypia); III (eg, severe atypia or melanoma in situ); IV (eg, pathologic stage T1a (pT1a) early invasive melanoma); and V (eg, ≥pT1b invasive melanoma). Reproducibility was assessed by intraobserver and interobserver concordance rates, and accuracy by concordance with three reference diagnoses. Results In phase 1, 187 pathologists completed 8976 independent case interpretations resulting in an average of 10 (SD 4) different diagnostic terms applied to each case. Among pathologists interpreting the same cases in both phases, when pathologists diagnosed a case as class I or class V during phase 1, they gave the same diagnosis in phase 2 for the majority of cases (class I 76.7%; class V 82.6%). However, the intraobserver reproducibility was lower for cases interpreted as class II (35.2%), class III (59.5%), and class IV (63.2%). Average interobserver concordance rates were lower, but with similar trends. Accuracy using a consensus diagnosis of experienced pathologists as reference varied by class: I, 92% (95% confidence interval 90% to 94%); II, 25% (22% to 28%); III, 40% (37% to 44%); IV, 43% (39% to 46%); and V, 72% (69% to 75%). It is estimated that at a population level, 82.8% (81.0% to 84.5%) of melanocytic skin biopsy diagnoses would have their diagnosis verified if reviewed by a consensus reference panel of experienced pathologists, with 8.0% (6.2% to 9.9%) of cases overinterpreted by the initial pathologist and 9.2% (8.8% to 9.6%) underinterpreted. Conclusion Diagnoses spanning moderately dysplastic nevi to early stage invasive melanoma were neither reproducible nor accurate in this large study of pathologists in the USA. Efforts to improve clinical practice should include using a standardized classification system, acknowledging uncertainty in pathology reports, and developing tools such as molecular markers to support pathologists’ visual assessments.
