Authors: DeRoy-Ringuette Rachel , Montesinos-Gelet Isabelle , Laplante Audrey
Published: April 2019

L’approche-programme est l’un des changements touchant l’enseignement supérieur, notamment pour les programmes de formation à l’enseignement. Si le Comité d’agrément des programmes de formation à l’enseignement (CAPFE) offre certaines balises (2012), il semble que le rôle du bibliothécaire dans la formation des futurs enseignants soit incertain ; or celui-ci peut avantageusement se positionner et contribuer à l’amélioration de la formation des étudiants. En prenant le cas des collections de littérature jeunesse disponibles dans les didacthèques pour les étudiants au baccalauréat en enseignement primaire et éducation préscolaire, nous explorons comment le bibliothécaire, en adoptant une posture de bibliothécaire intégré et en s’arrimant aux principes qui influencent la pédagogie de l’enseignement supérieur, peut participer à l’approche-programme implantée.

Weather change is one of the things that can affect people around the world in doing activities, including in Indonesia. The area of Indonesia, especially in Bandung regency has a high intensity of rainfall, compared with other regions. The people of Bandung Regency mostly have livelihoods in the fields of industry and agriculture, both of which are closely related to the effects of weather. Weather prediction is used for reference, so the future of society can prepare all possible weather before the move. One method of data mining used to predict weather is the association rule method. In this method there is Frequent Pattern Growth (FP-Growth) algorithm, this algorithm is used to determine the pattern of linkage between attribute weather with rainfall. The result of the FP-Growth algorithm is an association rule, the result of the algorithm rules is then used as reference for data entry in the classification process, where the process is done to get the forecast based on the rainfall category to obtain maximum accuracy. The highest performance result of FP-Growth from the result of rules based on its confidence value is 92%.

Background: The associations of the different blood gas parameters from different blood samples harvested at different stages during adult cardiac surgery with the postoperative outcomes are inadequately studied.
Methods: Adult patients undergoing elective cardiac surgery with cardiopulmonary bypass (CPB) participated in this prospective observational study. Blood gas parameters from arterial, central venous, and jugular venous blood samples harvested simultaneously at pre-determined time points (baseline with the patient awake, post-anesthesia induction but before CPB, during CPB at 30°C, during CPB at 37°C (rewarming), and at the end of surgery) were correlated with postoperative outcomes including the length of mechanical ventilation (LMV), intensive care unit stay (LICU), hospital stay (LOH), and major organ morbidity and mortality.
Results: Data from 193 patients were analyzed. Multiple parameters of different blood harvested at different stages significantly correlated with one or more outcome measures based on univariate analysis (p < 0.05). However, only the jugular venous blood pH and carbon dioxide tension and the central venous blood pH at the end of surgery (pHcv-end) were significantly correlated with LMV, LICU, and LOH (p < 0.05). A more alkaline blood correlated with more favorable outcomes. After adjusting for age, surgical time, and total intravenous volume administered, multivariate analysis showed that only pHcv-end remained independently associated with LMV and LICU (p < 0.05).
Conclusion: More alkaline blood, especially the central venous blood at the end of surgery, is associated with more favorable outcomes after adult cardiac surgery.

Background

To report the case of a surgical-induced necrotizing sclertitis (SINS) following vitreoretinal retinal surgery for rhegmatogenous retinal detachment, successfully managed by superficial muscle temporal fascia grafting.

Case presentation

An 18-year-old teenage, with a history of a twenty-three gauges vitrectomy with silicone oil tamponade forrhegmatogenous retinal detachment of the left eye presented two months after surgery with intense left ocular pain, decreased visual acuity to counting fingers and eye redness. Split lamp exam showed: conjunctival infiltration with silicone oil, circumferential sclera thinningpredominantly in the superonasal quadrant with ectasia of the underling uvea). The fundus examination showed an attached retina.

Necrotizing scleritis was the retained diagnosis. Performed etiological assessment was negative.Surgical induced necrotizing scleritis was the final diagnosis. An immunosuppressive therapy based on general corticoids was started. With the immanent risk of globe perforation, superficial muscle temporal fascia grafting was performed to cover the necrotizing sclera.The patient did well postoperatively without sclera thinning or ectasia and the fascia grafting still intact without retraction after six months of follow up.

Conclusion

This is the first case in the literature thatused the superficial temporal muscle fascia as a graft for sclera reinforcement in SINS. Wepropose a new support to reinforce the deficient sclera.This graft must be associated with prompt immunosuppressive therapy at high doses.

Background

Previous case reports presented the occurrence of ischemic optic neuropathy (ION) following intravitreal injections of antivascular endothelial growth factor (anti-VEGF). However, no previous studies have investigated the impact of injection numbers on the risk of ION. The aim of our study was to investigate whether repeated intravitreal injections of anti-VEGF would increase the risk of subsequent ION in patients with neovascular age-related macular degeneration (AMD).

Methods

A population-based, retrospective cohort study using the Taiwan National Health Insurance Research Database was conducted from 2007 to 2013. Neovascular AMD patients receiving intravitreal injections of anti-VEGF during the period were enrolled in the study cohort. Enrollees were divided into three groups according to categorized levels of injection number (first level: < 10 times, second level: 10–15 times, third level: > 15 times). Kaplan-Meier curves were generated to compare the cumulative hazard of subsequent ION among the three groups. Cox regression analyzes were used to estimate crude and adjusted hazard ratios (HRs) for ION development with respect to different levels of injection numbers. Confounders included for adjustment were age, sex, and comorbidities (diabetes, hypertension, hyperlipidemia, ischemic heart disease, and glaucoma).

Results

In total, the study cohort had 77210 patients. Of these, 26520, 38010, and 12680 were in the first, second, and third level groups, respectively. The Kaplan-Meier method revealed that the cumulative hazards of ION were significantly higher in those who had a higher injection number. After adjusting for confounders, the adjusted HRs for ION in the second and third levels of injection number were 1.91 (95% confidence interval [CI], 1.32–2.76), and 2.20 (95% CI, 1.42–3.43), respectively, compared with the first level.

Conclusions

Among patients with neovascular AMD, those who receive a higher number of anti-VEGF injections are at a significantly higher risk of developing ION when compared with individuals who receive a lower number of injections.

Published: April 2019

Background

Diagnosis and follow-up of retinal diseases may be improved if the thickness of the various retinal layers, in addition to the total retinal thickness, is taken into account. Here we measured the thickness of the macular retinal layers in a population-based study group to assess the normative values and their associations.

Methods

Using spectral-domain optical coherence tomographic images, we measured the thickness of the macular retinal layers in participants of the population-based Beijing Eye Study without ocular diseases and without arterial hypertension, hyperlipidemia and diabetes mellitus.

Results

The study included 384 subjects (mean age:60.0±8.0 years). In multivariable analysis, the thickness of the retinal layers in the foveal region, of all retinal layers except for the outer plexiform layer in the parafoveal area, and the thickness of the ganglion cell layer, inner plexiform layer and inner and outer nuclear layer in the perifoveal area decreased with older age (all P<0.05). Men as compared to women had higher thickness measurements of the photoreceptor layer and outer nuclear layer in all areas, and of all layers between the retinal nerve fiber layer and inner nuclear layer in the parafovea area. The associations between the macular retinal layers thickness and axial length were not consistent. The inner plexiform layer was thicker, and the ganglion cell layer and inner nuclear layer were thinner, in the temporal areas than in the nasal areas,

Conclusions

The associations between decreasing thickness of most retinal layers with older age and the correlation of a higher thickness of some retinal layer layers with male gender may clinically be taken into account.
Ocular flora in patients with intravitreal injections and topical antibiotic prophylaxis: antibiotic resistance patterns and susceptibility to antiseptic picloxydine
Authors: PhD Doctor of science Budzins Maria , Khalatyan Anait , Strakhovskaya Marina , Zhukhovitsky Vladimir
Published: April 2019

Background

Repeated courses of topical ophthalmic antibiotics result in the increased resistance rates and changes in the composition of conjunctival flora with the significant increase of Staphylococcus epidermidis, the main causative agent of ocular infections. Antiseptic povidone-iodine is considered as a “gold standard” for prevention of infectious complications in eye surgery. Effectiveness of pre- and post-injection prophylaxis with topical antiseptics is under question.

Methods

Conjunctival swabs were taken in 4 groups of patients, 20 patients in each group (n=80): with 20 or more IVI and repeated courses of antibiotic eye drops; without IVI and ophthalmic operations in history (control group); with antibiotic eye drops Tobrex or antiseptic eye drops Vitabact (picloxydine) applied 3 days before the first IVI and 5 days after it. In the last two groups swabs were taken at baseline and after the treatment. Bactericidal effectiveness of picloxydine was studied in vitro against antibiotic sensitive and resistant conjunctival isolates. Minimal inhibition concentration was determined with microdilution test.

Results

Two out of three potent ophthalmic patients showed conjunctiva bacterial contamination. Along with few Staphylococcus aureus and Gram-negative isolates susceptible to most antibiotics, the majority (71 ‒ 77%) were coagulase-negative staphylococci (CoNS), 40-50% of which multidrug resistant (MDR). Eye disinfection in the operating room and peri-injection courses of Tobrex or Vitabact resulted in total elimination of isolates found at baseline. However, in 10 and 20% patients, respectively, recolonization of the conjunctiva with differing strains occurred. In patients with repeated IVI and Tobrex/Maxitrol treatment, the conjunctival flora showed high resistance rates: 90% of CoNS were MDR. In the in vitro study, picloxydine showed bactericidal effect against staphylococci isolates regardless of their antibiotic sensitivity with MIC ≥ 13,56 µg/ml. Incubation of bacteria for 15 min in Vitabact eye drops, commercially available form of picloxydine, 434 µg/ml, showed total loss of colony forming units of all tested isolates including Pseudomonas aeruginosa.

Conclusions

The confirmed bactericidal efficacy of picloxydine against conjunctival bacterial isolates and the presence of its commercial form, 0,05% eye drops, convenient for use by patients before and after injection, makes this eye antiseptic promising for prophylaxis of IVI-associated infectious complications.

Franz Brentano’s Influence on Ukrainian Philosophy: A Methodological Introduction to Research
Authors: Ivanyk Stepan
Published: April 2019

This article ponders, for the first time, the question of whether Austrian philosopher Franz Brentano (1838-1917) influenced the development of the school of Ukrainian philosophy. It employs Anna Brożek’s methodology to identify philosophers’ influence on one another (distinctions between direct and indirect influence, active and passive contact, etc.); concepts of institutional and ideological conditions of this influence are also considered. The article establishes, first, that many Ukrainian academics had institutional bonds with Brentano’s students, especially Kazimierz Twardowski at the University of Lviv. Second, it identifies an ideological bond between Brentano and his hypothetical Ukrainian “academic grandsons.” Particularly, a comparative analysis of works on the history of philosophy of Brentano and the Ukrainian Ilarion Svientsits'kyi (1876-1956) reveals that the latter took over Brentano’sa posteriori constructive method. These results allow to draw a conclusion about the existence of Ukrainian Brentanism, that not only brings new arguments into the discussion about the tradition of and prospects for the development of analytic (scientific) philosophy on Ukrainian ground, but also opens new aspects of the modernization of Ukrainian society in general (from the end of the nineteenth century to the present day).
Democratic Transition Research: From Western to Post-Soviet East European Scholarship
Authors: Oleinikova Olga
Published: April 2019

This paper is the first of its kind to provide a comparative overview of Western (Western European and North American) and post-Soviet East European transition theories and literature that can be used to understand specifics of post-Soviet transition in Eastern Europe. Bridging the two broad theoretical traditions of East and West, and taking Ukraine as a case study, this literature review adds to the transition literature a discussion that relates to the emergence and interplay of structure and agency theories since the 1950s. In particular, the review sets out the various ways in which the transition from post-Communist government to democracy has been theorized, from a structuralist to an agency-structure approach. Meanwhile, it puts new wind into the sails of the idea that the interplay of structure and agency is more relevant to understanding the transition in Ukraine—reflecting similar dynamics in other post-Communist Eastern European states. This review is a good starting source for those who want to understand the roots of democratic transition research and theories.
