Patient Motivation for Laser in situ Keratomileusis in the State of Bihar
Authors: Akhaury Ranjan Kr , Verma N P , Kumar Ranjana
Published: December 2019

ABSTRACT

PURPOSE: To evaluate the main reasons for seeking laser in situ keratomileusis (LASIK) and patient satisfaction after surgery in the socioeconomically underdeveloped eastern state of Bihar, India.

METHODS: This retrospective study evaluated results of the first 100 consecutive patients (169 eyes) who had LASIK at our center from July 2002 to September 2003.

RESULTS: Of the 100 patients, 65% were male and 35% were female. Ninety percent of male patients were between 18 and 24 years old; they sought LASIK to achieve an uncorrected visual acuity of 6/6 to 6/9-the basic qualifying criterion for jobs in the railway and defense services. Eighty-six percent of female patients were of marrying age. At 1 month after LASIK, 93% of patients achieved an UCVA of 6/6, 4% had UCVA between 6/9 to 6/12, and only 1% had <6/60.

CONCLUSION: In the socioeconomically poor state of Bihar, the main reason for males in our study to seek LASIK was to enhance their job prospects. In females, the main reason was to improve facial appearance in order to enhance marriage prospects. [J Refract Surg 2004;20(suppl): S727-S729]

Authors: Doga Alexander V , Shpak Alexander A , Sugrobov Victor A
Published: December 2019

ABSTRACT

PURPOSE: To perform a quantitative evaluation of smoothness of ablation on polymethylmethacrylate (PMMA) using four scanning excimer lasers available commercially for photorefractive surgery.

METHODS: Ablations were done on PMMA plates with dimensions 100 x 50 x 1 mm. Four scanning excimer lasers were used, two with flying spot technology (Zeiss-Meditec MEL-70, and a Russian-made unit, Microscan) and two Nidek models with scanning slit delivery systems and an expanding iris diaphragm (EC-5000 and EC-5000 CX). Forty PMMA plates were ablated with standard -3.00-D settings using an ablation zone of 6 mm; each laser ablated 10 plates. Measurements were made in the center of each plate with the Zygo microscope, based on the principle of white light interferometry. Smoothness of ablation was characterized by three surface parameters (RMS, Ra, PV). RMS was considered the most significant parameter.

RESULTS: The smoothest surface was obtained in samples produced by Zeiss-Meditec MEL-70 unit (RMS=112±23 nm), followed by the Nidek EC-5000 CX (RMS=153±12 nm), and the Microscan (RMS=181±11 nm). The smoothness of ablation produced by the Nidek EC-5000 unit (RMS=329±39 nm) was significantly less than the other three lasers (P<.01).

CONCLUSIONS: Scanning excimer lasers based on flying spot technology-Zeiss-Meditec MEL-70 and Microscan, as well as the Nidek EC-5000 CX with FlexScan-created smoother ablations on PMMA plates compared to the older Nidek EC-5000 unit. [J Refract Surg 2004;20(suppl):S730-S733]

Published: December 2019

ABSTRACT

PURPOSE: The aim of this study was to quantify how closely the Nidek OPD-Scan objective refraction correlated with subjective refraction.

METHODS: A retrospective audit of the preoperative refraction of 80 myopic and myopic astigmatic eyes before laser in situ keratomileusis (LASIK) or laser supepithelial keratomileusis (LASEK) was performed. Objective refraction in the 5-mm zone was performed using a Nidek OPD-Scan. Subjective refraction was performed by a senior optometrist. Statistical analysis of sphere, cylinder, and spherical equivalent refraction measurements was then performed.

RESULTS: Spherical measurements correlated well with a linear regression equation, with a correlation coefficient of 0.97. Cylinder measurements correlated less well, with a correlation coefficient of 0.85. Spherical equivalent refraction measurements correlated well, with a correlation coefficient of 0.97. Analyzing the numerical difference between each objective refraction and its corresponding subjective refraction, the majority of values were only 0.50 D apart for sphere, cylinder, and spherical equivalent refraction.

CONCLUSION: There was good correlation between objective OPD-Scan and subjective refraction, especially for sphere and spherical equivalent refraction measurements, with regression gradients and correlation coefficients close to 1. [J Refract Surg 2004;20(suppl):S734-S736]

Authors: Güell José L , Velasco Fortino , Guerrero Eugenio , Gris Oscar , Pujol Jaume
Published: December 2019

ABSTRACT

PURPOSE: We evaluated short-term results and confocal microscopic corneal changes following intracorneal lens implantation.

METHODS: In six eyes of three patients with hyperopia between +3.00 and +6.00 diopters (D), an intrastromal hydrogel lens (Permavision, Anamed, Anaheim, Calif) was implanted. Mean baseline hyperopia was +3.90 D. Manifest refraction, uncorrected visual acuity, and spectacle-corrected visual acuity were evaluated. We also performed confocal real-time microscopy with a water immersion objective. Corneal optical sections were recorded and reviewed frame by frame. Examinations were done at months 3, 6, and 12 after intracorneal lens implantation.

RESULTS: After surgery, the spherical equivalent refraction was within ±0.50 D in 83% (five of six eyes) at 3 months and 100% (six eyes) at 6 and 12 months. Uncorrected visual acuity (UCVA) at 3 months was within 20/40 or better in 67% (four eyes) and in 100% (six eyes) at 6 and 12 months; no eyes had 20/20 or better UCVA at 3 and 6 months. One eye (17%) had 20/20 or better UCVA at 12 months. On confocal microscopy, one eye had an amorphous deposit adjacent to the lens and presumed fibroblastic activity in the same stromal area at 6 months, which was non-progressive up to 12 months.

CONCLUSION: Intracorneal lenses may be a treatment option for correction of spherical hyperopia. Predictability must be improved but results in these six eyes were stable up to 1 year. Confocal miscroscopy confirmed biocompatibility and showed no abnormal changes, except two spots of hypercellularity in one eye. [J Refract Surg 2004;20:778-782]
Alcohol and Mechanical Scraping for Epithelial Ingrowth Following Laser in situ Keratomileusis
Authors: Lahners William J , Hardten David R , Lindstrom Richard L
Published: December 2019

ABSTRACT

PURPOSE: To determine whether the use of 70% isopropyl alcohol is useful as an adjunct to simple mechanical removal of epithelial ingrowth following laser in situ keratomileusis (LASIK).

METHODS: A retrospective comparison of two techniques of epithelial ingrowth removal following LASIK was performed. A total of 38 procedures on 31 patients were included. In one group, the epithelium was removed using a simple mechanical scraping technique and in the other, a similar technique combined with the application of 70% isopropyl alcohol was used. The rates of recurrence in the two groups were compared using a chi-square analysis.

RESULTS: The total incidence of epithelial ingrowth recurrence in both groups was 57.9% (22/38). The incidence of clinically significant ingrowth recurrence in both groups was 34.2% (13/38). In the scrape group, the recurrence of any ingrowth was 43.8% (7/16) and the recurrence of clinically significant ingrowth was 31.3% (5/16). In the alcohol group, these rates were 68.2% (15/22) and 36.4% (8/22), respectively. The difference between the two groups did not show statistical significance in either comparison (P=.14 and P=.75, respectively).

CONCLUSIONS: The use of 70% isopropyl alcohol showed no additional benefit over simple mechanical scraping in the removal and prevention of epithelial ingrowth recurrence following LASIK. [J Refract Surg. 2005;21:148-151.]
Effect of a Yellow Filter on Contrast Sensitivity and Disability Glare After Laser in situ Keratomileusis Under Mesopic and Photopic Conditions
Authors: Pérez-Carrasco Ma Jesús , Puell Ma Cinta , Sánchez-Ramos Celia , López-Castro Angel , Langa Antonio
Published: December 2019

ABSTRACT

PURPOSE: To analyze the effect of a yellow filter on contrast sensitivity and disability glare under mesopic and photopic luminance conditions in laser in situ keratomileusis (LASIK) patients and control subjects.

METHODS: Contrast sensitivity with and without glare was determined in 27 patients who had undergone LASIK at least 1 year previously and in 30 control subjects. Tests were performed with and without a coated yellow filter (X-482 nm cut-off) using the Mesotest II or Mesoptometer II (Oculus, Wetzlar, Germany) under mesopic conditions, and the Contrast Glaretester 1000 (Takagi, Seiko Co Ltd, Nagano, Japan) under photopic conditions.

RESULTS: Under mesopic conditions, log contrast sensitivity without glare decreased by 0.14 log units in the LASIK group. When the yellow filter was used, this variable showed a significant increase of 0.04 log units and the proportion of patients able to discriminate the mesopic contrast limit of 1:5 rose from 70% to 78%. With glare, the yellow filter also improved contrast sensitivity in LASIK patients, but not significantly. Under photopic conditions, no statistical differences were observed between results obtained with and without the yellow filter in the LASIK group or between the LASIK and control group without glare.

CONCLUSIONS: Mesopic contrast sensitivity without glare was worse in LASIK patients and increased significantly with the yellow filter. The filter had no effect under photopic conditions. No disability glare differences were noted between the LASIK and control groups or between the LASIK without and with filter groups under mesopic and photopic conditions.

Published: December 2019

ABSTRACT

PURPOSE: To determine the possible impact of conductive keratoplasty (CK) on intraocular pressure (IOP) measurements.

METHODS: A prospective, single-center, noncomparative interventional case series was performed. Baseline and postoperative IOPs were measured by Goldmann applanation tonometry in 32 eyes of 18 patients who underwent CK for hyperopia correction. Mean follow-up was 11.9 months (range: 8 to 18 months).

RESULTS: After CK, a statistically significant decrease in the measured IOP was observed (before CK: 14.22±1.64 vs after CK: 12.66±2.21, P<.001). The change in IOP readings postoperatively was not correlated with age, sex, keratometric readings, or attempted correction.

CONCLUSIONS: Despite the limitations due to the small number of patients enrolled in this study, the applanation tonometer appears to underestimate the true IOP after CK. [J Refract Surg. 2005;21:171-175.]

Published: December 2019

ABSTRACT

PURPOSE: To report two cases of herpes simplex virus (HSV) keratitis after laser in situ keratomileusis (LASIK).

METHODS: Interventional small case series. Two patients underwent uneventful LASIK. History of herpes labialis in one patient and herpetic eye disease >10 years prior to intervention in the other patient was reported. Both patients developed stromal herpetic keratitis 6 weeks and 2 years after the procedure, respectively.

RESULTS: Treatment consisting of topical steroid drops and topical and systemic antiviral therapy was administered. Recurrences of the herpetic keratitis were seen after tapering of the topical steroids; four and three recurrences were observed, respectively. Final visual acuity was >6/9 in both cases.

CONCLUSIONS: Herpetic keratitis after LASIK is an uncommon, possibly under-reported, entity. Even patients without history of herpetic eye disease can present with this complication. Oral antiviral prophylaxis may be appropriate when performing LASIK on patients with a history of ocular or systemic HSV infection. [J Refract Surg. 2005;21:400-402.]

Published: December 2019

ABSTRACT

PURPOSE: To report a method of treatment for through-the-flap multibacterial ulcerative keratitis after laser in situ keratomileusis (LASIK).

METHODS: Bacterial ulcerative keratitis after LASIK was treated with topical and systemic antibiotics followed by flap lifting, cleaning, and phototherapeutic keratectomy (PTK). Follow-up examinations included in vivo confocal microscopy, corneal topography, and wavefront analysis.

RESULTS: Rapid recovery of the ulcerative keratitis was observed after flap lifting and cleaning of the interface and PTK combined with topical and systemic antibiotics. Two years postoperatively, corneal topography showed a slight depression of the ulcer area and decentration of the photoablation. Wavefront analysis revealed an irregular scan with a pronounced coma-like aberration, which with a wavefront-guided custom test lens correction provided 20/16 visual acuity.

CONCLUSIONS: Ulcerative bacterial keratitis is a possible sight-threatening complication of LASIK refractive surgery. Lifting and rinsing the flap combined with cleaning of the flap interface with PTK may be helpful in these conditions when regression of the ulcer does not occur with topical and oral antibiotic treatment.

Naive human T cells are produced and developed in the thymus, which atrophies abruptly and severely in response to physical or psychological stress. To understand how an instance of stress affects the size and "diversity" of the peripheral naive T cell pool, we derive a mean-field autonomous ODE model of T cell replenishment that allows us to track the clone abundance distribution (the mean number of different TCRs each represented by a specific number of cells). We identify equilibrium solutions that arise at different rates of T cell production, and derive analytic approximations to the dominant eigenvalues and eigenvectors of the mathematical model linearized about these equilibria. From the forms of the eigenvalues and eigenvectors, we estimate rates at which counts of clones of different sizes converge to and depart from equilibrium values-that is, how the number of clones of different sizes "adjusts" to the changing rate of T cell production. Under most physiological realizations of our model, the dominant eigenvalue (representing the slowest dynamics of the clone abundance distribution) scales as a power law in the thymic output for low output levels, but saturates at higher T cell production rates. Our analysis provides a framework for quantitatively understanding how the clone abundance distribution evolves under small changes in the overall T cell production rate.
Joaquim M. Bartrina, cervantista

Ampliando el conocimiento del polifacetismo de Joaquim M. Bartrina, se estudian diversos trabajos o proyectos suyos sobre Cervantes, en especial su contribución al inventario de la presencia del Quijote en el teatro, y las referencias a esta novela en su producción literaria (una epístola poética imitando el poema de Urganda la Desconocida al Quijote, tres pensamientos en verso o prosa y una narración invirtiendo los estereotipos sociales de don Quijote y Sancho, desarrollada por Josep Miró i Folguera). Bartrina, manteniendo la adscripción romántica del primer personaje al ideal y del segundo a la realidad, pero desde una óptica positivista, concluye que ambos representan dos aspectos del hombre.

Published: December 2019

Process control is an essential aspect in chemical engineering, which has been emphasized in Dynamic and Control Process course (KKKR 3684) the-oretically and through a conventional laboratory experimental, A2 (Tuning and Control) for hands-on learning. The tank level is chosen as the con-trolled variable to introduce control scheme to students. This conventional lab uses an old version facility and requires constant maintenance resulting lab schedule being postponed several times. Besides that, every experiment must be carried out in a group of four to five students thus the access and learning time per student is limited. As an alternative to this conventional laboratory, a mobile-based virtual lab has been designed to cater the limita-tions using a mobile application. The proposed virtual lab is known as MyAras and is developed using Android Studio software of version 2.3.3, which also a strategy to facing the 4.0 Industrial revolution. MyAras is a mobile virtual application and time independent, cost-effective, easy access and provides unlimited self-learning period for all students. Level 1 means the mobile virtual lab is still in the development stage and has not been fully launched to students. A questionnaire has been given to students and lectur-ers regarding their awareness and the importance of mobile virtual lab prior to its development. Preliminary study has found that 81% of students have shown their interest in running the virtual lab and 38.1% of students had never used such application as their practical learning tool.
Les maîtres du jeu
Authors: Onimus Clément
Published: December 2019

L’avènement du sultan Barqûq sur le trône du royaume syro-égyptien en 1382 est perçu dans l’historiographie comme l’événement qui distingue l’époque turque de la période circassienne du sultanat mamlouk.

Si rupture il y a eu, elle n’est toutefois pas tant ethnique que politique, marquant l’évolution de la nature du régime. La restauration de la dignité sultanienne et l’élaboration d’un nouveau discours de légitimité vont de pair avec la concentration des ressources fiscales au sein de la Maison du sultan, celle-ci étant confrontée néanmoins, dans le même temps, à la multiplication des conflits opposant les membres de l’élite militaire, les émirs. Au-delà des enjeux symboliques et économiques que se disputent ces officiers du sultanat, la lutte politique s’élabore autour de l’extension d’un capital social fondé sur des réseaux clientélistes. Dans cette compétition politique, les sultans successifs rivalisent avec de puissants émirs pour affirmer leur patronage sur l’élite militaire et s’imposer comme les maîtres du jeu.

Ce livre se saisit de la « dynastie barqûqide » en tant que laboratoire d’observation anthropologique de la conflictualité dans le sultanat mamlouk. Entre exclusion des émirs et intégration dans les réseaux, démonstration de force théâtralisée et violence anomique, la forme des conflits suit l’évolution de la nature du régime pour mener trente ans plus tard, en 1412, à la chute de la dynastie. L’ouvrage remet ainsi en question la périodisation classique en faisant de l’exécution du fils de Barqûq, le sultan Faraj, la véritable fondation du régime circassien.

Clitoria ternatea L. is a vital ayurvedic herb featured with a wide spectrum of mental health benefits. The present study investigates the competence of the plant against depression and to inhibit the membrane efflux protein P-glycoprotein (P-gp) that can regulate and restrict drug permeation into the brain. Antidepressant competence of the aqueous plant extract was assessed by animal despair studies on depression induced female mice models. The P-glycoprotein inhibitory potential of active phytocompounds was evaluated by molecular docking assay and substantiated by a cell line study. The in vivo studies exhibited a significant difference in the immobility time thereby establishing antidepressant activity. The histopathological sections from cortex region of treated brain showed decreased degenerative changes. Ten imperative phytocompounds facilitated docking complexes against P-glycoprotein among which Kaempferol 3-O-(2״,6״-di-O-rhamnopyranosyl) glucopyranoside exhibited a finest docking score of -12.569 kcal mol-1. Conversely it was attested by the rhodamine transport assay that demonstrated the inhibitory potential to surpass blood brain barrier. The outcome of the study endorses the efficacy of Clitoria ternatea L. as an idyllic brain drug and facilitates brain permeability

Phthiraptera are lice highly adapted to living as permanent and obligatory ectoparasites of birds and mammals. High infestations by biting lice contribute to the low productivity, loss quality of the eggs, besides weight decrease of chickens. Therefore, this study aimed to evaluate and to characterize the risks involved with the presence of biting lice in laying chicken from Minas Gerais, Brazil, throught a Multiple Correspondence Analysis (MCA). A secondary database with information regarding 402 chicken houses from 42 properties of laying hens from the same region was used and adapted for this study. The variables that composed the correspondence model were selected through Chi-square tests (p ≤ 0.05). A risk index was designed to relate the presence of biting lice out of variables such as risk factors related to the presence of these ectoparasites. The MCA graphic designed to conduct the epidemiological characterization of the presence of biting lice presented a Chi-square accumulated value of 53.59%. There was an association between the risk index and the synanthropic birds, subsistence hens, presence of lice and other ectoparasites in shelters and ectoparasites control. These results provide knowledge about the Phthiraptera epidemiology. Besides that, this information may contribute to the decision-making process in order to reduce the risk of possible infestations in poultry farms and the negative effects of the infestations.

The reproductive process promotes morphophysiological and behavioral changes in fish species throughout their life cycle. Its success is vital to define their resilience in the environment. This study aimed to evaluate the reproductive biology of the endemic fish species Astyanax bifasciatus in a tributary of the Lower Iguaçu River Basin, Paraná, Brazil. Fish were collected monthly at four sites along the Jirau Alto River in the city of Dois Vizinhos from October 2015 to September 2016. A standardized catch effort with gill nets and fish traps was used. In the laboratory, standard length and total weight were recorded. After anesthesia, the animals were sectioned to macroscopically determine the sex, sexual maturity stage, and presence of celomatic fat. The gonads and liver were removed to determine the gonadosomatic and hepatosomatic indexes, respectively. A total of 160 individuals (104 females and 56 males) were used. The gonadosomatic index, frequency of the gonadal maturation stages, and condition factor showed a long reproductive period with two investment cycles for both sex. Length at first sexual maturity was 4.57 cm for females and 3.56 cm for males. The reproductive data corroborate the generalist profile of the species and demonstrate a high degree of adaptive capacity, even in smaller tributaries.
Sodium and nitrate favor the steady state of cyanobacteria in a semiarid ecosystem
Authors: Oliviera Fábio Henrique Portella Corrêa de , Dantas Ênio Wocyli
Published: December 2019

This study characterized steady state events (SS) in a semiarid reservoir (Brazil) dominated by cyanobacteria for 130 weeks, and evaluated the influence of different abiotic variables on their occurrence. It was hypothesized that, in semiarid reservoirs, steady state events are independent from seasonality and influenced by high nutrient concentrations, and steady state periods show low variation of species. Our data revealed the occurrence of SS events in both the dry and wet seasons. Higher concentrations of nitrate and sodium together with higher values of color favored the development of SS. Species composing the SS dominated by Microcystis aeruginosa (Kützing) Kützing was correlated with higher sulfate concentrations, while higher values of turbidity and sodium concentrations favored the SS of Cylindrospermopsis raciborskii (Woloszynska) Seenaya and Suba Raju and Planktothrix agardhii (Gomont) Anagnostidis and Komárek. The results supported the hypothesis and showed the importance of variables rarely evaluated in works of this nature, such as sodium and sulfate in SS establishment of cyanobacteria.

Published: December 2019

Nesta pesquisa, analisamos a variação sociolinguística entre as formas de tratamento de segunda pessoa, tú e usted, em 36 entrevistas extraídas do corpus PRESEVAL (Proyecto para el Estudio Sociolinguístico del Español de Valencia). As 1.286 ocorrências coletadas, sendo 1.185 relativas à variante tú e 101 à variante usted, foram analisadas estatisticamente no programa Goldvarb (2005) para detectarmos a incidência de motivações linguísticas (tipo referente e tipo de discurso) e extralinguísticas (idade, sexo e escolaridade). O programa selecionou como significativos os seguintes grupos de fatores: i) tipo de referente, com o fator indeterminado como favorecedor da variante tú; ii) faixa etária, grupo em que a forma tú foi predominante nos indivíduos da faixa etária mais jovem; iii) tipo de discurso, no qual a variante supracitada demonstrou ser condicionada por discurso reportado de terceiros. Os resultados, interpretados à luz de pressupostos sociofuncionalistas, relevam atuação de princípios cognitivos: marcação, expressividade retórica, iconicidade e especialização por generalização.
Uso dos róticos do português em contato com os dialetos italianos
Authors: Comiotto Ariela Fátima , Margotti Felício Wessling
Published: December 2019

O objetivo deste trabalho é investigar a realização dos róticos nos estados do Rio Grande do Sul e de Santa Catarina. Nosso interesse está na realização da variável /R/ no contato entre o português e os dialetos italianos trazidos pelos imigrantes no século XIX. Na língua portuguesa (PB), tanto a vibrante simples quanto a múltipla são fonemas possíveis de realização, podendo ocorrer em ataque silábico, no início das palavras e em posição intervocálica, ou em coda de sílaba. Já no PB em contato com os falares dialetais italianos, a realização da vibrante múltipla, ou vibrante alveolar [r], conhecida como r-forte, pode alternar com a realização do tepe [ɾ] ou r-fraco. Uma das caraterísticas do português falado por bilíngues português-italiano no Sul do Brasil é o uso da vibrante simples (r-fraco) em lugar da múltipla, resultado das transferências dos falares italianos para o português. A hipótese aqui testada é que, nessas comunidades de fala, a vibrante alveolar [r] e o tepe [ɾ] são as variantes mais produtivas na fala dos indivíduos em situação de contato português com dialetos italianos. A metodologia empregada se deu a partir do Atlas Linguístico do Brasil (ALiB) e foram consideradas treze respostas (palavras) obtidas por meio do Questionário Fonético-Fonológico. O corpus é constituído de 108 respostas dos participantes para cada palavra e a realização da variável foi observada em dois contextos: posição intervocálica e início de palavra, como, por exemplo, ‘terreno’ e ‘rosa’.

Published: December 2019

Orchestes fagi (Linnaeus) (Coleoptera: Curculionidae) is a pest of beech trees (Fagus sylvatica Linnaeus; Fagaceae) in Europe that has recently become established and invasive on American beech (Fagus grandifolia Ehrhart) in Nova Scotia, Canada. We tested the effects of trap type, trap colour, trap height, and lure on the numbers of O. fagi captured per trap with the objective of developing a survey tool to monitor the weevil’s spread. We captured O. fagi in significantly greater numbers on yellow, green, or white traps than on light blue, dark blue, or red traps. There were no significant interactions between trap colour and trap design. Sticky triangular prism traps caught significantly more O. fagi than did nonsticky intercept traps regardless of colour. No effect of trap height was observed. Mean catch of O. fagi was significantly greater on yellow sticky triangular prism traps than on commercially sourced yellow sticky cards. Baiting yellow, green, or white sticky prism traps with the host volatile 9-geranyl-p-cymene did not increase catch of O. fagi. Our results suggest that yellow, green, or white sticky prism traps are a useful tool for detecting O. fagi adults and monitoring the spread of this species in Canada.

Something old, something new: revisiting the diamondback moth (Lepidoptera: Plutellidae) life table after 65 years

Published: December 2019

Nearly 65 years ago, D.G. Harcourt developed the first of 74 life tables of the diamondback moth, Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), on the Central Experimental Farm in Ottawa, Ontario, Canada and at nearby sites. This work is cited whenever authors discuss the life history of the diamondback moth and its parasitoids in Canada. Since Harcourt’s study, climate change, urbanisation, and crop diversity may have altered the population dynamics of both the diamondback moth and its natural enemy community in the original study area. To follow up on Harcourt’s work, we used two approaches to build life tables to describe mortality factors in the field and the natural enemies attacking diamondback moth in Ottawa: destructive sampling of mature cabbage, Brassica oleracea Linnaeus (Brassicaceae), plants similar to Harcourt’s approach and a modern sentinel-based approach with an enemy exclusion cage treatment. After 65 years, the primary parasitoids attacking diamondback moth remained the same, although more parasitoid diversity was revealed by the destructive sampling technique. Total mortality and parasitism levels also remained similar. In one notable difference, we attributed more diamondback mortality to predation. Overall, however, diamondback moth population dynamics have changed little in Ottawa in the decades since Harcourt’s studies.

Tinnitus is defined as perception of a sound without sound stimulation. This study aims to investigate the correlation between chronic tinnitus and the most significant clinical comorbidities and pharmacological treatments. We recruited 130 consecutive outpatients with a tinnitus for least from three months and 100 subjects without tinnitus. All patients had a full medical and audiological evaluation and all filled in Tinnitus Handicap Inventory questionnaire and Khalfa’s Hyperacusis questionnaire. We also analyzed the qualitative variables: audiometry exam, tinnitus characteristics and psychometric questionnaires. Univariate logistic regression was performed to evaluate the associations between the presence of tinnitus and the presence of comorbidities and drug intake. The statistical analysis provided the following results in the group of patients with tinnitus. We obtained an Odds Ratio statistically significant for the following categories taken into consideration: the presence of anxiety and depression, neurological diseases, headache, temporomandibular joint (TMJ) disorders, intake of levothyroxine and proton-pump inhibitor. In this study, we tried to evaluate the audiological characteristics in the subjects affected by chronic tinnitus in order to find a possible correlation with the comorbidities and any drugs intake. We found a statistically significant correlation between tinnitus and comorbidities like anxiety, depression, TMJ disorders, dysthyroidism, headache and levothyroxine and PPI intake.

Published: December 2019

The Interest Section on Therapist Training and Development of the Society for Psychotherapy Research (SPRISTAD) has launched a multisite collaborative longitudinal study of psychotherapy trainees’ development, a large-scale study involving a number of countries all over the world. In the present article, we present an overview of the early Italian contribution to the SPRISTAD study, based on preliminary paper-and-pencil data collection. Our preliminary findings showed cross-sectional differences at different years of training and two-years longitudinal changes in trainees’ perceived development. Moreover, trainees’ characteristics such as their motivation, relational manner, current life, and personal background have shown to deserve attention in research on trainees’ development. These findings encourage the continuation of the SPRISTAD online data collection.
Reporting of Concussion-Like Symptoms After Cycling Crashes: A Survey of Competitive and Recreational Cyclists
Authors: Rice Sarah , Iaccarino Mary Alexis , Bhatnagar Saurabha , Robidoux Greg , Zafonte Ross , Kotler Dana H.
Published: December 2019

Context

Cycling crashes are common among recreational and competitive riders and may result in head and bodily trauma. Information is limited regarding the signs and symptoms of head injury (HI) after cycling crashes, medical treatment, and recovery.

Objectives

To evaluate concussion-like symptom reporting after cycling crashes with or without HI in recreational and competitive cyclists and to assess crash characteristics and follow-up medical care.

Design

Cross-sectional study.

Setting

Voluntary online survey.

Patients or Other Participants

A convenience sample of 780 cyclists residing in the United States: 528 males, 249 females, 2 gender queer/nonbinary, and 1 transgender female.

Main Outcome Measure(s)

Survey-based, self-reported signs and symptoms of HI, including the third edition of the Sport Concussion Assessment Tool (SCAT3) symptom checklist, loss of consciousness, posttraumatic amnesia, and helmet damage.

Results

Of the participants, 403 reported crashes in the previous 2 years. Cyclists who self-reported no significant injury after their crash were excluded, leaving 77 HI reporters (HI group) and 260 trauma controls (TC group). The HI group more frequently reported experiencing 17 of the 22 symptoms on the SCAT3 symptom checklist. The HI group described a 4-fold higher incidence of loss of consciousness (HI = 13/77 [16.9%] versus TC = 11/2600 [4.2%]) and memory loss immediately after the crash (HI = 44/77 [57.1%] versus TC = 37/260 [14.2%]). The HI group reported major, noncosmetic helmet damage 2.5 times more frequently than the TC group (HI = 49/77 [63.6%] versus TC = 67/260 [25.8%]).

Conclusions

The findings suggest that a standardized concussion assessment is needed for cyclists who experience major trauma.

Concepções sobre avaliação educacional de intelectuais acadêmicos brasileiros nos anos 1980
Authors: Borges Regilson Maciel , Rothen José Carlos
Published: December 2019

O artigo discute a constituição do campo da avaliação educacional no Brasil a partir das concepções de intelectuais acadêmicos brasileiros que ajudaram a construir esse campo de conhecimento ao longo da década de 1980. Para esse fim, realizou-se uma pesquisa de caráter bibliográfica e documental, associada às estratégias dos estudos bibliométricos e à análise de conteúdo. Os dados foram organizados em duas principais abordagens de avaliação educacional, uma que enfatiza a avaliação como resultado e a outra cujo enfoque da avaliação é o processo. Nessas abordagens, as concepções dos intelectuais indicam que a avaliação é uma atividade inerente ao fazer humano e por isso não pode ser reduzida a uma ação mecânica, pois implica numa relação de poder e de negociação entre avaliador e avaliado.
Entre silêncios e silenciamentos: relações de gênero, sexualidades e ensino de História
Authors: Castro Roney Polato de , Ferrari Anderson , Santos Michele Priscila Gonçalves dos , Pedrosa Marilda Paula de
Published: December 2019

O presente artigo é parte de uma pesquisa, já concluída, que buscou investigar as relações entre cultura visual, currículo, formação docente e educação. Como instrumento metodológico foi aplicado um questionário qualitativo com questões abertas. Neste texto, vamos trabalhar com as respostas das alunas do curso de Pedagogia de uma universidade pública federal a duas questões que diziam sobre o ensino de História, as relações de gênero e as sexualidades. Estamos tomando o espaço escolar e o ensino de História como produtores e veiculadores de relações de gênero e sexualidades e, por conseguinte, como responsáveis por processos de silêncios e silenciamentos que afetam os modos de subjetivação, constituindo modos dos sujeitos se colocarem no mundo e de pensarem a si mesmos. Uma problemática de investigação e de análise que nos aproxima da perspectiva pós-estruturalista, sobretudo de inspiração foucaultiana, que entende a educação como um processo mais amplo de constituição dos sujeitos que ocorre na produção de discursos e saberes.
Percepção dos gestores sobre a inclusão de estudantes com deficiência na educação superior
Authors: Costa Joana Maria de Moraes , Pieczkowski Tania Mara Zancanaro
Published: December 2019

Este artigo está alicerçado nos estudos realizados na pesquisa de Mestrado em Educação, cujo objetivo foi analisar como o acesso de estudantes com deficiência na educação superior reverbera nas práticas de gestão universitária, no que se refere aos direitos desse público. Esta produção promoveu discussões sobre como os gestores avaliam a expansão do ingresso de estudantes com deficiência na universidade. Para este estudo, foram entrevistados gestores atuantes em quatro universidades, localizadas no município de Chapecó-SC. A imersão analítica ocorreu através da perspectiva da Análise do Discurso com referenciais foucaultianos. O estudo permitiu inferir que na contemporaneidade, a inclusão está permeada pelos discursos amparados numa visão normativa inquestionável e pouco problematizada, em que os avanços na democratização e expansão do acesso à universidade são representados através de números estatísticos divulgados como promissores.
