title: Short-term effects of intravitreal dexamethasone implant (OZURDEX®) on choroidal thickness in patients with naive branch retinal vein occlusion

description: ABSTRACT Purpose: The objective of this study was to evaluate subfoveal choroidal thickness (SFCT) using enhanced depth imaging optical coherence tomography (EDI-OCT) in patients with naïve branch retinal vein occlusion (BRVO) before and after intravitreal dexamethasone implant (Ozurdex®) injection. Methods: Thirty-nine patients with unilateral BRVO and 35 healthy subjects were included in this prospective study. Choroidal thickness was evaluated by EDI-OCT at baseline and 1 month after dexamethasone implant. Results: The mean SFCT measured in 39 patients with BRVO was 299.41 ± 55.86 µm, significantly greater than that in contralateral eyes (283.76 ± 57.44 µm; p=0.009) and control eyes (276.14 ± 39.06 µm; p=0.044). The mean SFCT after the treatment was 279.64 ± 50.96 µm, significantly thinner than that before intravitreal dexamethasone therapy (p=0.004). Conclusions: SFCT in treatment-naive BRVO eyes was significantly greater than that in contralateral eyes and healthy eyes and decreased significantly after intravitreal dexamethasone implantation.

title: Multivariate techniques in the analysis of carcass traits of Morada Nova breed sheep

description: ABSTRACT: This study aimed to use multivariate techniques of principal component analysis and canonical discriminant analysis in a data set from Morada Nova sheep carcass to reduce the dimensions of the original data set, identify variables with the best discriminatory power among the treatments, and quantify the association between biometric and performance traits. The principal components obtained were efficient in reducing the total variation accumulated in 19 original variables correlated to five linear combinations, which explained 80% of the total variation present in the original variables. The first two principal components together accounted for 56.12% of the total variation of the evaluated variables. Eight variables were selected using the stepwise method. The first three canonical variables were significant, explaining 92.25% of the total variation. The first canonical variable showed a canonical correlation coefficient of 0.94, indicating a strong association between biometric traits and animal performance. Slaughter weight and hind width were selected because these variables presented the highest discriminatory power among all treatments, based on standard canonical coefficients.

title: Comparison of the efficacy of 0.03% tacrolimus eye drops diluted in olive oil and linseed oil for the treatment of keratoconjunctivitis sicca in dogs

description: ABSTRACT Objective: To compare the efficacy of 0.03% tacrolimus eye drops diluted in two different vehicles (linseed oil and olive oil) for the treatment of keratoconjunctivitis sicca (KCS) in dogs. Methods: This study included 60 dogs. Of this group, 20 were healthy and allocated to the control group, and 40 were diagnosed with bilateral KCS and randomly allocated to either the TO (tacrolimus in olive oil) or the TL (tacrolimus in linseed oil) groups. Ophthalmic examinations, Schirmer Tear Test-1 (STT-1), Tear Film Break-up Time (TBUT) and Fluorescein Test (FT) were carried out monthly, along with cytological and histopathological examinations at the beginning and end of the study. Results: The clinical signs, corneal ulcers, Schirmer Tear Test-1 values, and Tear Film Break-up Time values improved in both groups after one month of treatment. Cytological examination at the end of the study showed decreased lymphocytes, neutrophil, metaplastic, and squamous cell counts in both groups, while the histopathological analysis showed decreases in lymphocytes and neutrophils and an increase in goblet cell density (cells/mm2). The decreases in neutrophil count were more significant (p&lt;0.05) in the TL group for both types of examination. Conclusion: In sum, 0.03% tacrolimus eye drops diluted in olive oil and linseed oil were effective in the treatment of keratoconjunctivitis sicca. None of the evaluated parameters differed significantly between the two groups, except for neutrophil count which was significantly lower in the TL group. Thus, linseed oil may be considered as an alternative diluent for tacrolimus eye drops.

title: Effects of isometric resistance training on blood pressure and physical fitness of men

description: Abstract AIMS The present study aimed to investigate the effects of whole body isometric resistance training (IRT) on blood pressure (BP), strength and aerobic fitness. We also analyzed whether the effects of whole body isometric training compares to whole body dynamic resistance training (DRT). METHODS Twenty-nine pre-hypertensive sedentary males, aged between 40 and 60 years were divided into three groups: IRT (n = 10), DRT (n = 9), and Control (n = 10). Both programs involved whole body resistance training, and occurred for 12 weeks, three times/week, at an intensity of 60% of a dynamic one repetition maximum test (1RM). Before and after 12 weeks, 24 hours blood pressure monitoring, 1RM strength and aerobic fitness were assessed. RESULTS IRT reduced diastolic BP values during a 24-hour period and daytime. There was also a decrease in mean BP values during daytime (P&lt;0.05). No interaction between time and group in systolic BP, diastolic BP, mean BP, heart rate and arterial stiffness index were observed (P&gt;0.05). IRT increased strength and aerobic fitness when compared to Control group. However, these changes were lower than DRT regarding strength (DRT: ∆ = 43.1±10.6% vs. IRT: ∆ = 24.1±7.1% vs. CON: Δ = 4.2±11.5%; P&lt;0.05) and aerobic fitness (DRT: ∆ = 22.9±10.7% vs. IRT: ∆ = 12.9±6.1% vs. CON: Δ = -2.1±7.4%; P&lt;0.01). CONCLUSION Whole body IRT reduced diastolic BP and mean BP, however, the decrease was not different for the DRT group. IRT also increased strength and aerobic fitness, nevertheless, these changes were lower than after DRT.

title: TRADE UNIONISM OF THE ABC DURING THE LULA ERA: CONTRADICTION AND RESISTANCE

description: Abstract Since the political confrontation and strikes during the 1964 Brazilian military dictatorship, the metalworker trade unionism of the ABC has created viable conditions of defending its economic demands in the public sphere, and at the same time has become a political force in Brazil. The election of Lula in 2002 and his permanence in this position for eight years (2003-2010) were the confirmation of the political strength of this trade unionism, which established new parameters and influenced in the organization of the workers in the country. Based on statistical data collection on work and employment in the ABC region, this paper seeks to determine an association between the economic and political context of the Lula/Dilma period and the strategies of the metalworkers trade union, taking into account its clear political relationship with the Brazilian Workers´ Party, especially with a worker president. The objective is to evaluate, as a result of this relationship, the existence of advancements or regressions in the union’s struggles for better wages, new job opportunities, approximating themselves to civil society, and its attempt to interfere in the debate about regional development strategies.

title: Effects of oral propranolol for circumscribed choroidal hemangioma

description: ABSTRACT Purpose: We aimed to evaluate the effects of oral propranolol for circumscribed choroidal hemangioma. Methods: In this prospective, longitudinal interventional study, we administered oral propranolol at a dosage of 1.5 mg/kg/day to five patients with circumscribed choroidal hemangioma. We then evaluated visual acuity, binocular indirect ophthalmoscopy, optical coherence tomography, optical coherence tomography angiography, fluorescein and indocyanine green angiography, and ocular ultrasonography at regular intervals and compared changes from the baseline assessments. Results: No clinical or diagnostic changes were observed in the sizes of the circumscribed choroidal hemangiomas during treatment. Complications due to the hemangioma were reduced in the first four months of treatment, followed by maintenance, before worsening in the subsequent three months. Conclusions: The study showed that oral propranolol at a dose of 1.5 mg/kg/day did not offer effective monotherapy in the treatment of circumscribed choroidal hemangioma.

title: Measurements of anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter using two Scheimpflug imaging devices

description: Purpose: To compare the ocular anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, as measured with two different Scheimpflug imaging devices. Methods: This transversal study included 80 right eyes from 80 subjects aged from 20 to 40 years. Their spherical equivalents ranged from -4.25 to +1.00 diopters (D). Each eye's anterior chamber depth, white-to-white distance, anterior chamber angle, and pupil diameter, were measured for far vision using both the Galilei G4 (double Scheimpflug camera) and the Pentacam HR (single Scheimpflug camera) systems. Results: Mean anterior chamber depths were calculated as 3.12 ± 0.23 mm and 3.19 ± 0.24 mm when measured with the Galilei G4 and the Pentacam HR, respectively. The mean white-to-white distance measured was 11.84 ± 0.31 mm and 11.90 ± 0.43 mm when measured with the Galilei G4 and the Pentacam HR, respectively. Mean pupil diameters were measured as 3.22 ± 0.58 mm and 3.22 ± 0.52 mm when measured with the Galilei G4 and the Pentacam HR, respectively. Finally, the mean anterior chamber angle was 34.30 ± 2.86 degrees when it was measured with the Galilei G4, and 39.26 ± 2.85 degrees when measured with the Pentacam HR. A comparative analysis revealed that the Galilei G4 yielded a significantly lower (P&lt;0.05) measurement for the anterior chamber depth, anterior chamber angle, and pupil diameter, than the Pentacam HR system. Comparable values (P&gt;0.05) for both devices were obtained for the white-to-white distance measurements. Conclusion: The Galilei G4 and Pentacam HR Scheimpflug systems cannot be used interchangeably because they produce significant measurement differences.

title: The role of pattern-reversal electroretinography in the diagnosis of glaucoma

description: Pattern electroretinography is used to assess the function of the inner retinal layers, particularly the retinal ganglion cell layer, using a reversing checkerboard or grating pattern that maintains a constant overall mean luminance over time. A normal transient response comprises a positive component of the wave (P50) followed by a longer negative component of the wave (N95). Glaucomatous optic neuropathy causes progressive loss of retinal ganglion cells, potentially detectable as abnormalities on examination, particularly in the N95 component. Therefore, pattern electroretinography may be useful in the diagnosis and evaluation of glaucoma. The present article is an updated review of published data regarding the use of pattern electroretinography for the detection of glaucoma-induced retinal changes.

title: Long-term outcomes with Boston type 1 keratoprosthesis in ocular burns

description: ABSTRACT Purpose: To evaluate the long-term outcomes of Boston type I keratoprosthesis (B-Kpro) in the management of patients with ocular burn injuries. Methods: This prospective study included all patients with ocular burns who underwent B-Kpro implantation at a tertiary eye care center between February 2008 and November 2015. Twelve patients (12 eyes) were enrolled. The procedures performed for managing ocular injury were identified, and information on ocular history, surgical procedures performed, and postoperative outcomes was collected. The main outcome measures were visual acuity, prosthesis retention, postoperative complications, and required surgical procedures. Results: Twelve eyes from 12 patients met the inclusion criteria for B-Kpro implantation, including nine eyes with alkali burns and three eyes with thermal burns. A total of 13 B-Kpro devices were implanted in the 12 eyes. The mean follow-up period was 60.8 months (range, 13-91 months). Preoperative best-corrected visual acuity ranged from counting fingers to light perception. Postoperative best-corrected visual acuity was better than 20/200 in 83.3%, 66.6%, and 57.1% of patients at 12, 48, and 60 months, respectively. The initial keratoprosthesis was retained in 10 (83.3%) eyes and was successfully replaced in one eye. The major cause of worsening of initial visual acuity was advanced glaucoma (four of 12 eyes). Conclusion: The anatomical and functional results support the use of B-Kpro for managing bilateral limbal stem cell deficiency secondary to ocular burns. However, glaucoma should be carefully evaluated, as it is a continuous threat that may result in irreversible visual loss in this population.
