Motor skills in children affected by strabismus

Objectives: To compare motor skills in patients with infantile strabismus and age and sex-matched control subjects aged 5–11 years. Methods: Motor performances were assessed by the Italian version of Developmental Coordination Disorder Questionnaire 2007 (DCDQ) in children with infantile strabismus and age and sex-matched control subjects. Patients affected by specific neurological, cognitive and behavioural disorders were excluded from the study. Results: There were 43 patients included in the study, 23 in the strabismus group (14 males, 9 females, mean age 7.5 ± 2.0 years) and 24 in the control group (14 males and 10 females, mean age 7.2 ± 1.7 years. The overall DCDQ score was significantly lower in children with strabismus compared with control subjects (58.7 ± 11.3 vs. 74.2 ± 1.5; P < 0.001). Children with strabismus and no stereopsis showed a lower DCDQ score compared with those with normal stereopsis (50.8 ± 9.5 vs. 67.3 ± 4.8; P < 0.001). Conclusion: Motor skills are reduced in children with strabismus compared with control subjects. Strabismus and lack of binocular vision are factors potentially contributing to developmental coordination disorder

Risk Factors of Cystoid Macular Edema After Pars Plana Vitrectomy for Pseudophakic Retinal Detachment

Introduction: This study aimed to investigate the prevalence of cystoid macular edema after pars plana vitrectomy for the treatment of pseudophakic rhegmatogenous retinal detachment and identify possible related risk factors. Methods: A retrospective monocentric study was conducted within a cohort of pseudophakic patients undergoing vitrectomy for rhegmatogenous retinal detachment between January 2019 and December 2022. Demographic data, initial and intraoperative characteristics of rhegmatogenous retinal detachment, and postoperative data were analyzed. Cystoid macular edema was defined on optical coherence tomography exclusively. Results: A total of 164 eyes of 164 patients were included for analysis. The mean age of the patients at surgery was 65.7 ± 12.0 years. The mean best-corrected visual acuity was 2.1 ± 1.0 logMAR preoperatively and 1.0 ± 0.7 logMAR postoperatively. The mean follow-up was 13.4 ± 7.7 months. The prevalence of cystoid macular edema was 17.1% [9.8–26.4]. In multivariate analysis, severe proliferative vitreoretinopathy (relative risk 3.6 [1.3–9.7]) and laser retinopexy (relative risk 8.4 [1.1–64.7]) were independently and significantly associated with cystoid macular edema. Conclusion: The prevalence of cystoid macular edema in pseudophakic rhegmatogenous retinal detachment after pars plana vitrectomy was 17.1%. Severe proliferative vitreoretinopathy stage and the use of endolaser retinopexy were independent risk factors for development of cystoid macular edema

Exploring Response to Immunotherapy in Non-Small Cell Lung Cancer Using Delta-Radiomics

Delta-radiomics is a branch of radiomics in which features are confronted after time or after introducing an external factor (such as treatment with chemotherapy or radiotherapy) to extrapolate prognostic data or to monitor a certain condition. Immune checkpoint inhibitors (ICIs) are currently revolutionizing the treatment of non-small cell lung cancer (NSCLC); however, there are still many issues in defining the response to therapy. Contrast-enhanced CT scans of 33 NSCLC patients treated with ICIs were analyzed; altogether, 43 lung lesions were considered. The radiomic features of the lung lesions were extracted from CT scans at baseline and at first reassessment, and their variation (delta, 06) was calculated by means of the absolute difference and relative reduction. This variation was related to the final response of each lesion to evaluate the predictive ability of the variation itself. Twenty-seven delta features have been identified that are able to discriminate radiologic response to ICIs with statistically significant accuracy. Furthermore, the variation of nine features significantly correlates with pseudo-progression

Prevention of Progression in Myopia : a Systematic Review

The prevalence of myopia has increased worldwide in recent decades and now is endemic over the entire industrial world. This increase is mainly caused by changes in lifestyle and behavior. In particular, the amount of outdoor activities and near work would display an important role in the pathogenesis of the disease. Several strategies have been reported as effective. Spectacles and contact lenses have shown only slight results in the prevention of myopia and similarly ortokerathology should not be considered as a first-line strategy, given the high risk of infectious keratitis and the relatively low compliance for the patients. Thus, to date, atropine ophthalmic drops seem to be the most effective treatment for slowing the progression of myopia, although the exact mechanism of the effect of treatment is still uncertain. In particular, low-dose atropine (0.01%) was proven to be an effective and safe treatment in the long term due to the lowest rebound effect with negligible side effects

Seed dormancy and seedling growth changes in response to scarification treatments and population origin in Kosteletzkya pentacarpos (Malvaceae)

Kosteletzkya pentacarpos is important for the restoration of coastal habitats in Asia and is vulnerable in Europe. Physical dormancy (PY) prevents ready seed germination and seedling production for restoration and conservation purposes. In this study, seed germination and seedling growth of K. pentacarpos were investigated in response to scarification treatments (manual scarification, percussion) and population origin (i.e., wild, cultivated ex situ and reintroduced). Manual scarification best promoted seed germination (98-100%), but resulted in damages to the cotyledons (on 64% of seedlings, on average) and lower seedling growth. Percussion did not significantly increase seed germination, but best promoted seedling growth. There was a significant reduction of PY in seeds produced by plants cultivated ex situ and/or reintroduced. Our results indicate that scarification treatments and ex situ cultivation may have important implications in translocation and other uses of K. pentacarpos

Outbreak of sars-cov-2 lineage 20i/501y.V1 in a nursing home underlines the crucial role of vaccination in both residents and staff

Elderly residents in nursing homes are at very high risk of life-threatening COVID-19-related outcomes. In this report, an epidemiological and serological investigation of a SARS-CoV-2 outbreak in an Italian nursing home is described. Among the residents, all but one (19/20) were regularly vaccinated against SARS-CoV-2. In mid-February 2021, a non-vaccinated staff member of the nursing home was diagnosed with the SARS-CoV-2 infection. Following the outbreak investigation, a total of 70% (14/20) of residents aged 77–100 years were found positive. The phylogenetic analysis showed that the outbreak was caused by the SARS-CoV-2 variant of concern 202012/01 (the so-called “UK variant”). However, all but one positive subjects (13/14) were fully asymptomatic. The only symptomatic patient was a vaccinated 86-year-old female with a highly compromised health background and deceased approximately two weeks later. The subsequent serological investigation showed that the deceased patient was the only vaccinated subject that did not develop the anti-spike protein antibody response, therefore being likely a vaccine non-responder. Although the available mRNA SARS-CoV-2 vaccine was not able to prevent several asymptomatic infections, it was able to avert most symptomatic disease cases caused by the SARS-CoV-2 variant of concern 202012/01 in nursing home residents

Plant communities of Italy. The vegetation prodrome

The Vegetation Prodrome of Italy was promoted in 2012 by the Italian "Ministry of Environment, Land and Sea Protection", in collaboration with the "Italian Society of Botany", to provide a comprehensive and systematic catalogue and description of Italian plant communities. The Prodrome that is presented in this paper is the first full organic synthesis of the vegetation of Italy at the alliance syntaxonomic level. It fulfils several needs, the main one being a unified and comprehensive national framework that may make an important contribution to the definition of the European Vegetation Prodrome. Syntaxonomy, as well as taxonomy, is sometimes based on considerations that may in part diverge: several authors tend to favour models that are divisive or aggregative to a greater or lesser extent in terms of flora, biogeography and ecology. These different points of view stimulate the scientific debate and allow the adoption of a framework that is more widely supported. The Prodrome includes 75 classes, 2 subclasses, 175 orders, 6 suborders and 393 alliances. The classes were grouped into nine broad categories according to structural, physiognomic and synecological elements rather than to syntaxonomic criteria. The rank, full valid name, any synonymies and incorrect names are provided for each syntaxon. The short declaration highlights the physiognomy, synecology, syndynamics and distribution of the plant communities that belong to the syntaxon. The Prodrome of the Italian Vegetation is linked to the European Strategy for Biodiversity, the European Habitats Directive and the European Working Groups related to the ecosystems and their services. In addition to basic applications, the Prodrome can be used as a framework for scientific research related to the investigation of the relationships between plant communities and the environmental factors that influence their composition and distribution
