As COVID-19 spread all over the world, most of the countries adopted some kind of restrictions to avoid the collapse of health systems. In Brazil, São Paulo and Rio the Janeiro, the two most populated cities in the country, were the first to determine social distancing. In this study, the impact of the social distancing measures on the concentrations of the three main primary air pollutants (PM10, NO2 and CO) was analyzed. CO levels showed the most significant reductions (up to 100%) since it is related to light-duty vehicular emissions. NO2 also showed reductions (9.1%-41.8%) while PM10 levels were only reduced in the 1st lockdown week. The decrease of pollutants was not directly proportional to the vehicular flux reduction, because it depends on other factors such as the transport of air masses from industrial and rural areas. The differences observed can be explained considering the fleet characteristics in the two cities and the response of the population to the social distancing recommendations.The objective of this study was to determine whether (a) cancer-related coping profiles change across time; (b) coping profile transition types predict changes in depressive and physical symptoms. Latent transition analysis was conducted with repeated measures of seven cancer-related coping processes from 460 women recently diagnosed with breast cancer. In multilevel models, coping profile transition groups were entered as predictors of symptoms across 12 months. Three coping profiles emerged at study entry, with two profiles at later assessments. Forty-eight percent of women maintained high-moderate approach-oriented coping over time. Specific factors (e.g., age, acceptance of emotions) differentiated the transition groups. Women who increased and then maintained high-moderate approach-oriented coping had relatively high initial depressive symptoms that declined steeply. When cancer-related acceptance predominated, women experienced increasing physical symptoms. Distinct cancer-related coping patterns are related to the level of and change in depressive and physical symptoms longitudinally. Early intervention to increase approach-oriented coping strategies could yield favorable outcomes.Purpose This study aims to evaluate the clinical features of adenoma of the retinal pigment epithelium (RPE) and eye-sparing treatment for it. Methods The patients underwent measurement of visual acuity and intraocular pressure, slit-lamp examination, ophthalmoscopy, fluorescein fundus angiography (FFA), indocyanine green angiography (ICGA), color Doppler imaging (CDI), and magnetic resonance imaging (MRI). The tumors were endoresected and studied histopathologically. Results Of the 16 Asian patients, 15 had RPE adenoma and 1 had RPE adenocarcinoma. Visual acuity decreased in three cases, mainly due to the macular detachment. All tumors were solitary and unilateral and measured from 1.7 × 3.2 × 2.4 to 9.3 × 8.0 × 6.6 mm3. Crenolanib concentration The tumor was located in the macular area in 2 patients, in the juxtapapillary area in 1 patient, and in the peripheral fundus in 13 patients. The tumors were yellow-pink in 3 patients and brown in 13 patients. The tumors showed hypofluorescence in early stage and mottled hyperfluorescence with prominent leakage in late stage on fluorescein angiography. CDI demonstrated arterial blood signals within tumor, and MRI demonstrated hyperintensity and hypointensity in the T1- and T2-weighted images, respectively. The tumors were positive for S-100, neuron-specific enolase (NSE), CK, epithelial membrane antigen (EMA), and vimentin; occasionally positive for melanin-A; and usually negative for melanoma-specific antigen HMB45 and synaptophysin (Syn). The endoresection surgery was performed in all 16 patients by the microinvasive vitrectomy for the excision of intraocular tumors and reconstruction of the eyeball. The follow-up time was 1.5-13 years (mean, 5 years). No tumor recurrence occurred, and the retina remained attached in 16 eyes. Conclusions RPE-derived adenomas are rare and difficult to diagnose clinically. Local resection by the mircoinvasive vitrectomy is a feasible alternative treatment for RPE adenoma.Purpose To investigate the optical coherence tomography (OCT) en face reconstruction of the choroid in different phenotypes of non-neovascular age-related macular degeneration (AMD), to identify the relative distribution of the vascular patterns of the Haller's layer in each AMD category. Methods Retrospective study enrolling consecutive patients with non-neovascular AMD. Patients were divided into the following (1) those with reticular pseudodrusen (RPD); (2) those with small ( less then 63 μm) or medium-large drusen (63-124 μm); (3) those with geographic atrophy (GA). Qualitative analysis of the en face images provided by CIRRUS HD-OCT 5000 (Carl Zeiss Meditech, Inc., Dublin, USA) was performed, identifying five arrangements of Haller's vessels temporal herringbone, branched from below, laterally diagonal, double arcuate, and reticular. Choroidal thickness (CT) was measured from structural OCT. Healthy age-matched subjects were included as a control group. Results Fifty-eight eyes of 58 patients (20 eyes with RPD; 22 eyes with drusen; 16 eyes with GA) and 18 control eyes were enrolled. The laterally diagonal configuration was the most prevalent (40.0%) in the RPD group; the reticular pattern was the most frequent in the drusen group (50.0%); the double arcuate (62.5%) was the most recurrent pattern in patients with GA. In the control group, the temporal herringbone (38.9%) arrangement was the most represented. The CT associated with the temporal herringbone and reticular arrangement was significantly higher compared to the branched from below (p less then 0.001), the laterally diagonal (p = 0.014), and the double arcuate pattern (p = 0.009). Conclusion Different phenotypes of non-neovascular AMD present a specific distribution of vascular arrangement on en face OCT. The temporal herringbone and the reticular pattern (the ones more associated in a physiological setting) disclosed a thicker choroid compared to the arrangements more represented in non-neovascular AMD-correlated phenotypes.
