Elevated fish densities extend kilometres from oil and gas platforms.

Thousands of offshore oil and gas platforms have been installed throughout the world's oceans and more structures are being installed as part of the transition to renewable energy. These structures increase the availability of ecological niches by providing hard substrate in midwater and complex 3D habitat on the seafloor. This can lead to 'hotspots' of biodiversity, or increased densities of flora and fauna, which potentially spill over into the local area.

Early identification can be made clinically, aided by dermoscopy, in addition to newer imaging technologies such as reflectance confocal microscopy. BCC most commonly demonstrates an indolent course responsive to local destruction or surgical removal.

Biometry and Intraocular Lens Power Calculation in Eyes with Prior Laser Vision Correction (LVC) - A Review.

Background: An intraocular lens (IOL) calculation in eyes that have undergone laser vision correction (LVC) poses a significant clinical issue in regards to both patient expectation and accuracy. This review aims to describe the pitfalls of IOL power calculation after LVC and give an overview of the current methods of IOL power calculation after LVC.

Review: Problems after LVC derive from the measurement of anterior corneal radii, central corneal thickness, asphericity, and the predicted effective lens position.

Update on Biometry and Lens Calculation - A Review of the Basic Principles and New Developments.

These days, accurate calculation of artificial lenses is an important aspect of patient management. In addition to the classic theoretical optical formulae there are a number of new approaches, most of which are available as online calculators. This review aims to explain the background of artificial lens calculation and provide an update on study results based on the latest calculation approaches.

Unconstrained coevolution of bacterial size and the latent period of plastic phage.

Viruses play critical roles in the dynamics of microbial communities. Lytic viruses, for example, kill significant fractions of autotrophic and heterotrophic microbes daily. The dynamic interplay between viruses and microbes results from an overlap of physiological, ecological, and evolutionary responses: environmental changes trigger host physiological changes, affecting the ecological interactions of host and virus and, ultimately, the evolutionary pressures influencing the two populations.

Ecosystem approach to harvesting in the Arctic: Walking the tightrope between exploitation and conservation in the Barents Sea.

Projecting the consequences of warming and sea-ice loss for Arctic marine food web and fisheries is challenging due to the intricate relationships between biology and ice. We used StrathE2EPolar, an end-to-end (microbes-to-megafauna) food web model incorporating ice-dependencies to simulate climate-fisheries interactions in the Barents Sea. The model was driven by output from the NEMO-MEDUSA earth system model, assuming RCP 8.

Patient Experience Surveys Reveal Gender-Biased Descriptions of Their Care Providers.

Patient experience surveys (PES) are collected by healthcare systems as a surrogate marker of quality and published unedited online for the purpose of transparency, but these surveys may reflect gender biases directed toward healthcare providers. This retrospective study evaluated PES at a single university hospital between July 2016 and June 2018. Surveys were stratified by overall provider rating and self-identified provider gender.

Evolutionarily Stable Coevolution Between a Plastic Lytic Virus and Its Microbial Host.

Hosts influence and are influenced by viral replication. Cell size, for example, is a fundamental trait for microbial hosts that can not only alter the probability of viral adsorption, but also constrain the host physiological processes that the virus relies on to replicate. This intrinsic connection can affect the fitness of both host and virus, and therefore their mutual evolution.

Evening wear of blue-blocking glasses for sleep and mood disorders: a systematic review.

Blue-blocking glasses, also known as amber glasses, are plastic glasses that primarily block blue light. Blue-blocking glasses have been studied as a sleep intervention for insomnia, delayed sleep-phase disorder, shift work, jet lag, and nonpathologic sleep improvement. Blue-blocking glasses have also been studied as a treatment for bipolar disorder, major depression, and postpartum depression.

Wearing the wolf skin: psychiatry and the phenomenon of the berserker in medieval Scandinavia.

This paper examines the berserker, a frenzied warrior attested to in both the written and material sources of medieval Scandinavia, and elucidates the characteristics that define him. It critiques explanations for the phenomenon offered in the existing historiography and whether this can be explained as a psychiatric diagnosis. It concludes that the berserker cannot be simply defined as a culturally bound or other psychiatric syndrome, or accounted for by psychogenic drugs alone.

The effect of viral plasticity on the persistence of host-virus systems.

Phenotypic plasticity plays an important role in the survival of individuals. In microbial host-virus systems, previous studies have shown the stabilizing effect that host plasticity has on the coexistence of the system. By contrast, it remains uncertain how the dependence of the virus on the metabolism of the host (i.

Pyoderma gangrenosum: a review with special emphasis on Latin America literature.

Pyoderma gangrenosum is a neutrophilic dermatosis characterized by chronic ulcers due to an abnormal immune response. Despite the existence of diagnostic criteria, there is no gold standard for diagnosis or treatment. In Latin America, recognizing and treating pyoderma gangrenosum is even more challenging since skin and soft tissue bacterial and non-bacterial infections are common mimickers.

Objective: To determine efficacy of modified Mohs micrographic surgery (mMMS) with en face permanent margins in management of invasive melanoma (IM) and melanoma in situ (MIS).

Methods: A retrospective cohort study evaluating local recurrence, 5-year recurrence-free survival, and 5-year melanoma-specific survival.

Carcinoma Erysipeloides From Metastatic Cutaneous Squamous Cell Carcinoma Initially Mistaken for Intralymphatic Histiocytosis.

Intralymphatic histiocytosis is a rare dermatologic disorder, commonly associated with inflammatory disorders and rarely malignancy. Carcinoma erysipeloides (CE) is a rare pseudoinflammatory cutaneous eruption that resembles soft -tissue infections as result of intralymphatic metastasis and subsequent lymphatic obstruction. Breast carcinoma represents most of the CE cases, but rarely other malignancies are involved.

Mechanisms of Inflammation in Neutrophil-Mediated Skin Diseases.

Neutrophil-mediated skin diseases, originally named neutrophilic dermatoses (NDs), are a group of conditions due to an altered neutrophil recruitment and activation, characterized by polymorphic cutaneous manifestations with possible internal organ involvement. Although a number of diseases are included in this setting, the two prototypic forms are pyoderma gangrenosum (PG) and Sweet's syndrome (SS) which usually present with skin ulcers and plaque-type lesions, respectively. They have central features significantly overlapping with autoinflammatory conditions which manifest as repeated episodes of tissue inflammation.

Insights Into the Pathogenesis of Sweet's Syndrome.

Sweet's syndrome, also known as Acute Febrile Neutrophilic Dermatosis, is a rare inflammatory condition. It is considered to be the prototype disease of neutrophilic dermatoses, and presents with acute onset dermal neutrophilic lesions, leukocytosis, and pyrexia. Several variants have been described both clinically and histopathologically.
