Metal concentrations in native and transplanted species in the Eastern Ionian Sea (Greece).

Metal concentrations (Cu, Cr, Ni, Zn, Fe, Mn, Cd, and Pb) in marine indicator species were assessed for the study of metal pollution in the Eastern Ionian Sea during the cold period of the year (December 2018 to February 2019). Limpets and sea urchins were collected from natural populations at seven coastal stations while mussels were transplanted at three near-shore stations in the study area. Mixed mesozooplankton samples were selected from a twelve-station offshore network.

Establishing Clinical Trial Endpoints in Selecting Patients for RPGR Retinal Gene Therapy.

Purpose: Clinical trials for X-linked retinitis pigmentosa (RP) often assess retinal structure using optical coherence tomography (OCT) and function using microperimetry to evaluate initial eligibility and endpoints. Therefore, we seek to determine which parameters might be most sensitive in screening new patients for enrollment.

Methods: Thirty-one patients (62 eyes) with confirmed retinitis pigmentosa GTPase regulator (RPGR) mutations attending Oxford Eye Hospital were included in this retrospective analysis.

Methods: This study was conducted from October 2020 to January 2022. The sample consisted of 1201 mothers with corresponding newborn births out of the total 7201 that took place during the same period.

Disseminated Cutaneous Mucormycosis Developing in Peristomal Pyoderma Gangrenosum.

A patient on long-term glucocorticoid therapy for peristomal pyoderma gangrenosum (PPG) who developed mucormycosis (MM) of the wound with dissemination was presented. The importance of skin biopsy, together with clinical evaluation in patients with PPG who are resistant to conventional therapy or who develop new symptoms related to their PPG is stressed. The risk and pathogenesis of invasive fungal infections with long-term corticosteroid therapy were explored.

Gene-Environment Interaction Between CYP1B1 and Oral Contraception on Frontal Fibrosing Alopecia.

Importance: Frontal fibrosing alopecia (FFA) is an increasingly prevalent form of follicular lichen planus, causing irreversible hair loss predominantly in postmenopausal individuals. An earlier genome-wide meta-analysis of female FFA identified risk loci in genes implicated in self-antigen presentation and T-cell homeostasis, including HLA-B*07:02, ST3GAL1, and SEMA4B. However, CYP1B1, which is important for hormone metabolism, was also implicated with the substitution of serine for asparagine at position 453 (c.

25G Pars Plana Vitrectomy-Lensectomy and Sulcus IOL Implantation for Patients with Cataract and Cornea Guttata.

Corneal guttata is a non-inflammatory progressive decline of endothelial cell density (ECD) which represents an early clinical feature of Fuch's dystrophy. In patients with corneal guttata, the relative risk for corneal transplantation after phacoemulsification has been found to be 68.2 times higher than in those without it.

Distribution of gamma-ray elements in Cerro do Jarau impact structure and a proposal of geothermal modeling.

Large meteorite impacts release kinetic energy that induces rock deformation, high temperatures and fluid circulation during the cratering process. To understand the correlation between rock deformation and fluid circulation, it is relevant to investigate post-impact hydrothermal flux and its relation to the local geology. The Cerro do Jarau impact structure is a ~13.

Motor Output Variability in Movement Disorders: Insights From Essential Tremor.

Findings on individuals with essential tremor suggest that tremor (within-trial movement unsteadiness) and inconsistency (trial-to-trial movement variance) stem from distinct pathologies and affect function uniquely. Nonetheless, the intricacies of inconsistency in movement disorders remain largely unexplored, as exemplified in ataxia where inconsistency below healthy levels is associated with greater pathology. We advocate for clinical assessments that quantify both tremor and inconsistency.

Unique Neural Mechanisms Underlying Speed Control of Low-Force Ballistic Contractions.

According to the speed-control hypothesis, the rate of force development (RFD) during ballistic contractions is dictated by force amplitude because time to peak force (TPF) remains constant regardless of changes in force amplitude. However, this hypothesis has not been tested at force levels below 20% of an individual's maximum voluntary contraction (MVC). Here, we examined the relationship between the RFD and force amplitude from 2 to 85% MVC and the underlying structure of muscle activity in 18 young adults.

Assessment of Maternal Retinal Microvasculature in Preterm Pregnancy Using OCT-Angiography: a Cross-Sectional Study.

Pregnancy induces a cascade of hemodynamic changes that are likely to affect the maternal systemic and ocular circulation. The current study aimed to investigate retinal microvasculature alterations in women with preterm and full-term pregnancy using optical coherence tomography angiography (OCT-A). This was a cross-sectional, comparative, single-center study.

Evaluation of the satisfaction and experiences of oncology patients and doctors using teleconsultation during the COVID-19 pandemic.

Introduction: During the coronavirus disease 2019 (COVID-19) pandemic, the Gustave Roussy Cancer Center introduced teleconsultation via telephone, as an alternative to face-to-face consultation to reduce patient hospital visits. This study was designed to assess patient and doctor satisfaction with this modality of care in oncology patient care during the period of the pandemic and beyond.

Methods: We designed two questionnaires based on validated scores to assess satisfaction from teleconsultation in patients (EORTC OUT-PATSAT 35 and Telemedicine Satisfaction Questionnaire [TSQ] scores) and doctors (Telehealth Usability Questionnaire [TUQ]), and anxiety levels in both groups (anxiety section of the Hospital Anxiety and Depression Scale [HADS], HADS-A).

Radial peripapillary capillary density as a predictive factor for glaucoma in eyes with ocular hypertension. An observational, comparative, single-centred study.

Ocular hypertension (OH) is a condition characterized by elevated intraocular pressure (IOP) exceeding the normal range, without any evident damage to the optic nerve or visual field defects characteristic of glaucoma. It constitutes a significant precursor to the development of glaucoma, a leading cause of irreversible vision loss worldwide. Emerging evidence has shown that microcirculation alterations in eyes with OH could serve as predicting factors to identify eyes at high risk for progression to glaucoma.

Visual Information Processing in Older Adults: Force Control and Motor Unit Pool Modulation.

Increased visual information about a task impairs force control in older adults. To date, however, it remains unclear how increased visual information changes the activation of the motor unit pool differently for young and older adults. Therefore, this study aimed to determine how increased visual information alters the activation of the motor neuron pool and influences force control in older adults.

A Rare Case of COVID-19 Related Acute Necrotizing Encephalopathy With the RANBP2 Mutation in a Pediatric Patient.

Acute necrotizing encephalopathy (ANE) is a rare childhood neurological disorder. The familiar type of ANE (ANE1) is associated with a mutation in the RANBP2 gene. Both SARS-CoV-2 and RANBP2 mutations are responsible for the manifestation of a hyper-inflammatory response that invades the central nervous system and plays a key role in the rapid progression of encephalopathy.

Long-term warming and human-induced plankton shifts at a coastal Eastern Mediterranean site.

Plankton are key ecological indicators for assessing the impacts of human-induced pressures like climate change and waste-water discharge. Here, 26 years (1988-2015) of biweekly in-situ chlorophyll-a concentration, mesozooplankton biomass and remotely-sensed sea surface temperature (SST) data are utilized to investigate long-term changes of plankton biomass and timing of growth (phenology) in relation to warming, in a coastal region of the Saronikos Gulf (Aegean Sea). A Waste-Water Treatment Plant (WWTP) was established in 1995, leading to decreased nutrient concentrations circa 2004.

Metal and metallothionein concentrations in mesozooplankton from an oligotrophic offshore area in the eastern Mediterranean Sea (Cretan Passage/Levantine Sea).

Spatial variability of Cd, Cu, Cr, Ni, Zn, Fe, Mn, Pb and metallothionein (MT) concentrations were determined in mesozooplankton samples along the west-east axis of the Cretan Passage in the western Levantine Sea (Eastern Mediterranean). Metal and MT values from the present study are proposed as background levels, due to the lack of substantial anthropogenic activities in the area, where only maritime traffic and atmospheric deposition could be potential sources. Higher concentrations, of both metals and MTs, were recorded mainly at the western stations indicating higher metal bioavailability than in the eastern part.

ECLAPTE: Effective Closure of LAParoTomy in Emergency-2023 World Society of Emergency Surgery guidelines for the closure of laparotomy in emergency settings.

Laparotomy incisions provide easy and rapid access to the peritoneal cavity in case of emergency surgery. Incisional hernia (IH) is a late manifestation of the failure of abdominal wall closure and represents frequent complication of any abdominal incision: IHs can cause pain and discomfort to the patients but also clinical serious sequelae like bowel obstruction, incarceration, strangulation, and necessity of reoperation. Previous guidelines and indications in the literature consider elective settings and evidence about laparotomy closure in emergency settings is lacking.
