Smooth Nylon Foil (SupraFOIL) Orbital Implants in Orbital Fractures: A Case Series of 181 Patients

Purpose: The SupraFOIL smooth nylon foil implant is a polyamide sheet available in varying thicknesses that has been used in orbital reconstruction following trauma. The authors report their experience with smooth nylon foil implants in the repair of orbital fractures. Methods: A retrospective chart review of patients having undergone repair of orbital fractures between January 1, 1995 and December 31, 2003 was conducted. The Wilcoxon test was used to compare cases with complications and those with no complications. Results: Of 282 orbits that underwent fracture repair with alloplastic material, 87 were excluded because non-nylon foil implants were used alone or in combination with nylon foil to repair the orbital fracture. An additional 14 fractures were excluded because of insufficient clinical data or lack of follow-up, for a total of 181 orbits that underwent orbital fracture repair with only nylon foil. A transconjunctival approach was used in 98% cases, and all 181 implants were fixated with at least 1 titanium screw. Average follow-up was 362.8 days. The overall complication rate was 1.7%. One patient had an acute postoperative orbital hemorrhage (0.6% acute complication rate). Two patients had late orbital infections, 683 days and 984 days following repair (1.1% late complication rate). Conclusions: The authors found the smooth nylon foil implant to be safe and effective in orbital fracture repair. The lower rate of complications the authors observed compared with previously reported series may be related to implant fixation. A titanium screw secured just posterior to the orbital rim may decrease long-term complications by providing more stability than implants left without fixation.
Dog Bite‐Induced Canalicular Lacerations: A Review of 17 Cases

Canalicular lacerations are frequently found in conjunction with other facial lacerations occurring in dog bite injuries. A review of the treatment of 17 dog bite-induced Canalicular lacerations is presented. Certain pathogens commonly found in the canine oral flora may cause severe secondary infections, which may result in sepsis and even death. These pathogens are reviewed along with a description of appropriate plans for antimicrobial prophylaxis. A surgical approach to such injuries is described.
Starch Biosynthesis in Guard Cells But Not in Mesophyll Cells Is Involved in CO2-Induced Stomatal Closing1[OPEN]

Stomatal CO2 response and assimilation rates of defined starch biosynthesis mutants (ADGase and pPGI) reveal that starch synthesis in guard cells but not mesophyll functions in CO2-induced stomatal closure. Starch metabolism is involved in stomatal movement regulation. However, it remains unknown whether starch-deficient mutants affect CO2-induced stomatal closing and whether starch biosynthesis in guard cells and/or mesophyll cells is rate limiting for high CO2-induced stomatal closing. Stomatal responses to [CO2] shifts and CO2 assimilation rates were compared in Arabidopsis (Arabidopsis thaliana) mutants that were either starch deficient in all plant tissues (ADP-Glc-pyrophosphorylase [ADGase]) or retain starch accumulation in guard cells but are starch deficient in mesophyll cells (plastidial phosphoglucose isomerase [pPGI]). ADGase mutants exhibited impaired CO2-induced stomatal closure, but pPGI mutants did not, showing that starch biosynthesis in guard cells but not mesophyll functions in CO2-induced stomatal closing. Nevertheless, starch-deficient ADGase mutant alleles exhibited partial CO2 responses, pointing toward a starch biosynthesis-independent component of the response that is likely mediated by anion channels. Furthermore, whole-leaf CO2 assimilation rates of both ADGase and pPGI mutants were lower upon shifts to high [CO2], but only ADGase mutants caused impairments in CO2-induced stomatal closing. These genetic analyses determine the roles of starch biosynthesis for high CO2-induced stomatal closing.
Xenopus pitx3 target genes lhx1 and xnr5 are identified using a novel three‐fluor flow cytometry–based analysis of promoter activation and repression

Background: Pitx3 plays a well understood role in directing development of lens, muscle fiber, and dopaminergic neurons; however, in Xenopus laevis, it may also play a role in early gastrulation and somitogenesis. Potential downstream targets of pitx3 possess multiple binding motifs that would not be readily accessible by conventional promoter analysis. Results: We isolated and characterized pitx3 target genes lhx1 and xnr5 using a novel three‐fluor flow cytometry tool that was designed to dissect promoters with multiple binding sites for the same transcription factor. This approach was calibrated using a known pitx3 target gene, Tyrosine hydroxylase. Conclusions: We demonstrate how flow cytometry can be used to detect gene regulatory changes with exquisite precision on a cell‐by‐cell basis, and establish that in HEK293 cells, pitx3 directly activates lhx1 and represses xnr5.

Intake of Fat-Soluble Vitamins in the Belgian Population: Adequacy and Contribution of Foods, Fortified Foods and Supplements

A key challenge of public health nutrition is to provide the majority of the population with a sufficient level of micronutrients while preventing high-consumers from exceeding the tolerable upper intake level. Data of the 2014 Belgian food consumption survey (n = 3200) were used to assess fat-soluble vitamin (vitamins A, D, E and K) intake from the consumption of foods, fortified foods and supplements. This study revealed inadequate intakes for vitamin A, from all sources, in the entire Belgian population and possible inadequacies for vitamin D. The prevalence of inadequate intake of vitamin A was lowest in children aged 3–6 (6–7%) and highest in adolescents (girls, 26%; boys, 34–37%). Except for women aged 60–64 years, more than 95% of the subjects had vitamin D intake from all sources below the adequate intake (AI) of 15 μg/day. The risk for inadequate intake of vitamins K and E was low (median > AI). Belgian fortification and supplementation practices are currently inadequate to eradicate suboptimal intakes of vitamins A and D, but increase median vitamin E intake close to the adequate intake. For vitamin A, a small proportion (1–4%) of young children were at risk of exceeding the upper intake level (UL), while for vitamin D, inclusion of supplements slightly increased the risk for excessive intakes (% > UL) in adult women and young children. The results may guide health authorities when developing population health interventions and regulations to ensure adequate intake of fat-soluble vitamins in Belgium.
Examining the impact of salesperson interpersonal mentalizing skills on performance: the role of attachment anxiety and subjective happiness

Due to the dynamic and interpersonal nature of selling, understanding affective and cognitive relationships and their influence on performance has gained the attention of sales scholars. Moreover, recent literature has created opportunities to study the impact of cognitions, such as salesperson theory-of-mind, on sales performance. This research develops a model involving salesperson interpersonal mentalizing skills (i.e. rapport building, detecting nonverbal cues, taking a bird’s-eye view, shaping the interactions), subjective happiness, attachment anxiety, and sales performance. Although salesforce optimization is critical in any economy, emerging economies are the growth frontier for many global companies. Using three samples from Brazil, we investigate the telecom, banking, and retail industries, providing generalizable results from one such emerging economy. We find that, in general, it is the influence of attachment anxiety and subjective happiness on interpersonal mentalizing skills which ultimately impacts sales performance. Based on these findings, we discuss several theoretical and managerial implications.
Cultivating microbial dark matter in benzene-degrading methanogenic consortia.

The microbes responsible for anaerobic benzene biodegradation remain poorly characterized. In this study, we identified and quantified microbial populations in a series of 16 distinct methanogenic, benzene-degrading enrichment cultures using a combination of traditional 16S rRNA clone libraries (four cultures), pyrotag 16S rRNA amplicon sequencing (11 cultures), metagenome sequencing (1 culture) and quantitative polymerase chain reaction (qPCR; 12 cultures). An operational taxonomic unit (OTU) from the Deltaproteobacteria designated ORM2 that is only 84% to 86% similar to Syntrophus or Desulfobacterium spp. was consistently identified in all enrichment cultures, and typically comprised more than half of the bacterial sequences. In addition to ORM2, a sequence belonging to Parcubacteria (candidate division OD1) identified from the metagenome data was the only other OTU common to all the cultures surveyed. Culture transfers (1% and 0.1%) were made in the presence and absence of benzene, and the abundance of ORM2, OD1 and other OTUs was tracked over 415 days using qPCR. ORM2 sequence abundance increased only when benzene was present, while the abundance of OD1 and other OTUs increased even in the absence of benzene. Deltaproteobacterium ORM2 is unequivocally the benzene-metabolizing population. This study also hints at laboratory cultivation conditions for a member of the widely distributed yet uncultivated Parcubacteria (OD1).
From membrane tension to channel gating: A principal energy transfer mechanism for mechanosensitive channels

Mechanosensitive (MS) channels are evolutionarily conserved membrane proteins that play essential roles in multiple cellular processes, including sensing mechanical forces and regulating osmotic pressure. Bacterial MscL and MscS are two prototypes of MS channels. Numerous structural studies, in combination with biochemical and cellular data, provide valuable insights into the mechanism of energy transfer from membrane tension to gating of the channel. We discuss these data in a unified two‐state model of thermodynamics. In addition, we propose a lipid diffusion‐mediated mechanism to explain the adaptation phenomenon of MscS.
Autoimmune Pancreatitis Can Transform Into Chronic Features Similar to Advanced Chronic Pancreatitis With Functional Insufficiency Following Severe Calcification

Objectives Because several studies for autoimmune pancreatitis (AIP) have revealed pancreatic calcification resembling that in chronic pancreatitis (CP), we sought to clarify whether AIP could transform into chronic features similar to advanced CP with severe pancreatic dysfunction. Methods Pancreatic functions of 92 AIP patients, 47 definite CP patients, and 30 healthy controls were assessed by fecal elastase-1 concentration (FEC), fasting immunoreactive insulin (IRI), and homeostatic model assessment (HOMA)-R. Results The 92 AIP patients included 17 (18%) with severe calcification (SC) and 75 without. The FEC levels in AIP and CP patients were significantly lower than that in controls. Exocrine insufficiency defined as FEC less than 200 &mgr;g/g was 39% in AIP without SC, 56% in AIP with SC, and 74% in CP. Fasting IRI and C-peptide reactivity values in CP were significantly lower than those in AIP, with no significant differences between AIP subgroups. The prevalence of endocrine insufficiency according to fasting IRI less than 5.0 &mgr;U/mL was 26% in AIP without SC, 31% in AIP with SC, and 59% in CP, respectively. HOMA-R values were significantly higher in all AIP groups than in CP. Conclusions Autoimmune pancreatitis can transform into a state of pancreatic insufficiency after calcification that is less severe than that in definite CP.
Lee Silverman Voice Treatment (LSVT)-BIG to improve motor function in people with Parkinson’s disease: a systematic review and meta-analysis

Objective: The technique called Lee Silverman Voice Treatment (LSVT)-LOUD has previously been used to improve voice quality in people with Parkinson’s disease. The objective of this study was to assess the effectiveness of an alternate intervention, LSVT-BIG (signifying big movements), to improve functional mobility. Design: Systematic review with meta-analysis of randomized trials. Data sources: Medline, Embase, CINAHL, AgeLine, Scopus and Cochrane Library were searched from inception to September 2017 using multiple search terms related to Parkinson’s disease and LSVT-BIG. Review method: Two researchers searched the literature for studies of the LSVT-BIG intervention of 16 sessions, delivered by a certified instructor over four weeks, to any other intervention. Outcomes related to functional ability were included. Study quality was appraised using the Cochrane Risk of Bias tool. Results: Four studies were included, reporting on three randomized trials of 84 participants with mild Parkinson’s disease. Compared to physiotherapy exercises, or a shorter training protocol, there was a significant improvement in motor function assessed with the Unified Parkinson’s Disease Rating Scale part III (mean difference = −3.20, 95% confidence interval = −5.18 to −1.23) and a trend towards faster Timed Up and Go performance (mean difference = −0.47, 95% confidence interval = −0.99 to 0.06) and 10-metre walk test (mean difference = −0.53, 95% confidence interval = −1.07 to 0.01). Conclusion: Compared to shorter format LSVT-BIG or general exercise, LSVT-BIG was more effective at improving motor function. This provides preliminary, moderate quality evidence that amplitude-oriented training is effective in reducing motor impairments for people with mild Parkinson’s disease.
Effectiveness of conservative treatment for patellofemoral pain syndrome: A systematic review and meta-analysis.

OBJECTIVE To evaluate the evidence regarding the effectiveness of conservative treatment in reducing patellofemoral pain. DATA SOURCES CENTRAL, MEDLINE, CINAHL, and PEDro databases. STUDY SELECTION Adults with patellofemoral pain, randomized controlled trials only, any conservative treatment compared with placebo, sham, other conservative treatment, or no treatment. Two independent reviewers. DATA EXTRACTION Data were extracted from the full-text of the articles, based on Cochrane Collaboration recommendations. The outcome of interest was the difference between groups regarding change in pain severity. DATA SYNTHESIS The majority of studies were underpowered. More than 80% of the 37 trials did not show a clinically significant benefit. Clinically significant effects of different sizes were found for 7 trials (6 studies out of 7 had short follow-ups). These effects were found for: (i) pulsed electromagnetic fields combined with home exercise -33.0 (95% CI -45.2 to -20.8); (ii) hip muscle strengthening -65.0 (95% CI -87.7 to -48.3) and -32.0 (-37.0 to -27.0); (iii) weight-bearing exercise -40.0 (95% CI -49.4 to -30.6); (iv) neuromuscular facilitation combined with aerobic exercise and stretching -60.1 (95% CI -66.9 to -54.5); (v) postural stabilization -24.4 (95% CI -33.5 to -15.3); and (vi) patellar bracing -31.6 (95% CI -35.2 to -28.0). CONCLUSION There is no evidence that a single treat-ment modality works for all patients with patellofemoral pain. There is limited evidence that some treatment modalities may be beneficial for some subgroups of patients with patellofemoral pain.
Nasopharyngeal Carcinoma With Orbital Involvement

Purpose: To describe the clinical presentation of patients with nasopharyngeal carcinoma and orbital involvement. Methods: A retrospective case series of 9 patients with nasopharyngeal carcinoma presenting with orbital involvement from March 2003 to April 2006 at the Singapore National Eye Centre were reviewed. The clinical profile, neuroradiologic evaluation, and clinical course of these patients were reviewed. Results: There were 3 women and 6 men with stage T4 disease. The mean age was 49.2 years ± 7.69 years (range, 37–57 years). The mean time from initial diagnosis of nasopharyngeal carcinoma to orbital involvement was 8.2 years (range, 0.8–29 years). One patient had no prior history of nasopharyngeal carcinoma. Four patients presented with an eyelid mass and 2 patients reported tearing. Other symptoms included diplopia, blurred vision, and protrusion of the eye. Imaging revealed tumor involvement of the orbital apex, inferior orbital fissures with intraconal spread, and infiltration of the lacrimal sac. The recurrences were confirmed histologically. Patients were treated with radiotherapy and/or chemotherapy. There were 3 deaths from advanced nasopharyngeal carcinoma during the follow-up period. The time interval from diagnosis of orbital involvement to death ranged from 8 months to 24 months. Conclusion: Ocular symptoms and signs may be the initial presentation of recurrent nasopharyngeal carcinoma. One must therefore be aware of possible tumor recurrence in patients with a prior history of nasopharyngeal carcinoma who present with symptoms of tearing or an eyelid mass, as this would enable prompt referral to the oncologist and otorhinolaryngologist.
Modeling Therapy Resistance in BRCA1/2-Mutant Cancers

Although PARP inhibitors target BRCA1- or BRCA2-mutant tumor cells, drug resistance is a problem. PARP inhibitor resistance is sometimes associated with the presence of secondary or “revertant” mutations in BRCA1 or BRCA2. Whether secondary mutant tumor cells are selected for in a Darwinian fashion by treatment is unclear. Furthermore, how PARP inhibitor resistance might be therapeutically targeted is also poorly understood. Using CRISPR mutagenesis, we generated isogenic tumor cell models with secondary BRCA1 or BRCA2 mutations. Using these in heterogeneous in vitro culture or in vivo xenograft experiments in which the clonal composition of tumor cell populations in response to therapy was monitored, we established that PARP inhibitor or platinum salt exposure selects for secondary mutant clones in a Darwinian fashion, with the periodicity of PARP inhibitor administration and the pretreatment frequency of secondary mutant tumor cells influencing the eventual clonal composition of the tumor cell population. In xenograft studies, the presence of secondary mutant cells in tumors impaired the therapeutic effect of a clinical PARP inhibitor. However, we found that both PARP inhibitor–sensitive and PARP inhibitor–resistant BRCA2 mutant tumor cells were sensitive to AZD-1775, a WEE1 kinase inhibitor. In mice carrying heterogeneous tumors, AZD-1775 delivered a greater therapeutic benefit than olaparib treatment. This suggests that despite the restoration of some BRCA1 or BRCA2 gene function in “revertant” tumor cells, vulnerabilities still exist that could be therapeutically exploited.

Development of a didactical training concept for peer tutors in gross anatomy

Even though peer tutors are often used in gross anatomy courses, research in the field is rather a subject of the last two decades. This is especially true about the didactical challenges these types of peer tutors experience during their tutorials and about how they are prepared for the task. The aim of the presented study was to learn about the training needs of the tutors, and to subsequently design, implement, and evaluate a didactical training concept. A qualitative design was chosen to examine how tutors can best be prepared for tutorials of gross anatomy. To do so, focus group interviews were conducted. The data were analyzed and grouped into various concepts, using semi‐structured interview questions as guidance. It was found that peer tutors are in need of training in the following aspects: Dealing with students who are experiencing difficulties during or as a result of dissection, dealing with group dynamics, that is, at the dissection table, keeping students motivated, time management, and staying confident as a tutor. In order to be regarded as useful and relevant in the eyes of tutors, a preparatory training course should include all these aspects in addition to general didactical training elements. Training needs of peer tutors of gross anatomy go beyond the content of standardized didactical curricula; therefore, tutors should be prepared with a curriculum that is specifically geared toward the many challenges associated with teaching gross anatomy to first year medical students which are already so well documented in the research literature.

Effects of early home language environment on perception and production of speech*

The effects of exposure to non-English heritage languages versus exposure to foreign-accented English during early childhood on language performances later in life were investigated. Three groups of young adult participants who differed in their early home language environment were examined on a series of linguistic tasks. Results showed that people who were mostly exposed to accented English in the early home environment are more native-like in various aspects of English language performance than those who were mostly exposed to their non-English heritage language, including vocabulary, pronunciation, and processing of certain types of speech stimuli. Early and extended exposure to accented speech, however, does not appear to enhance the ability to perceive foreign accents in general, and may in fact produce a disadvantage when listening to unfamiliar accents. These findings provide some initial insight into the consequences of migrant parents choosing to speak one language over the other with their children.
Changes in Health-Related Quality of Life During Rehabilitation in Patients With Operable Lung Cancer: A Feasibility Study (PROLUCA)

Introduction: Surgical resection in patients with non–small cell lung cancer (NSCLC) may be associated with significant morbidity, functional limitations, and decreased quality of life. Objectives: The objective is to present health-related quality of life (HRQoL) changes over time before and 1 year after surgery in patients with NSCLC participating in a rehabilitation program. Methods: Forty patients with NSCLC in disease stage I to IIIa, referred for surgical resection at the Department of Cardiothoracic Surgery RT, Rigshospitalet, were included in the study. The rehabilitation program comprised supervised group exercise program, 2 hours weekly for 12 weeks, combined with individual counseling. The study endpoints were self-reported HRQoL (Functional Assessment of Cancer Therapy–Lung, European Organization for Research and Treatment in Cancer–Quality of Life Questionnaire-QLQ-C30, Short-Form-36) and self-reported distress, anxiety, depression, and social support (National Comprehensive Cancer Network Distress Thermometer, Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support), measured presurgery, postintervention, 6 months, and 1 year after surgery. Results: Forty patients were included, 73% of whom completed rehabilitation. Results on emotional well-being (P < .0001), global quality of life (P = .0032), and mental health component score (P = .0004) showed an overall statistically significant improvement during the study. Conclusion: This feasibility study demonstrated that global quality of life, mental health, and emotional well-being improved significantly during the study, from time of diagnosis until 1 year after resection, in patients with NSCLC participating in rehabilitation.
