During a survey of the marine benthic diatom flora on the coasts off Livingston Island (South Shetland Islands, Maritime Antarctic Region), two species that could not be identified based on the currently available literature, were observed. Detailed light and scanning electron microscopy observations and thorough comparison with similar taxa in the literature revealed that both taxa should be described as new species. The first taxon, , was most likely misidentified in past Antarctic studies, and included within the range of another taxon, . Analysis of literature data showed that the second new taxon, , has been previously reported from the Antarctic Continent (but as an unidentified species). The new taxa are compared with similar taxa worldwide. Data on their ecology and distribution are also provided.

At the forefront of climate change and natural disasters, small islands like Puerto Rico confront immense challenges in sustaining an adaptive water supply. The challenges are further exacerbated when the islands' constraints, such as geographic isolation, limited resources, aging infrastructure, constrained capacity, and environmental fragility, are compounded. As these issues increasingly impact low-lying continental coasts, home to approximately 40 % of the global population, similar water supply crises have already emerged or are anticipated in these regions.

Article Synopsis
  • The study aimed to assess and compare aneuploidy rates and the chances of obtaining usable embryos in IVF cycles that used both preimplantation genetic testing for monogenic disorders (PGT-M) and aneuploidy (PGT-A) versus those that used PGT-A alone.
  • Conducted as a retrospective cohort study, it analyzed 72,522 IVF cycles from patients aged 18-45 over a period from November 2019 to March 2023 at a single genetics laboratory.
  • Results indicated that although the PGT-M+PGT-A group had a higher percentage of younger patients, there were no significant differences in aneuploidy rates between the two groups; however, PGT

Objective: Although the benefits of consumer involvement in research and health care initiatives are known, there is a need to optimize this for all people with cancer. This systematic review aimed to synthesize and evaluate the application of co-design in the oncology literature and develop recommendations to guide the application of optimal co-design processes and reporting in oncology research, practice, and policy.

Methods: A systematic review of co-design studies in adults with cancer was conducted, searching MEDLINE, CINAHL, Embase, and PsycINFO databases and included studies focused on 2 concepts, co-design and oncology.

The hidden Australian skin cancer epidemic, high-risk cutaneous squamous cell carcinoma: a narrative review.

Pathology

Deaths from non-melanoma skin cancers (NMSCs) have almost doubled in Australia in recent years. Cutaneous squamous cell carcinoma (cSCC) constitutes approximately 20% of NMSCs, but is responsible for most of the deaths. Most skin cancers are easy to diagnose and treat and therefore cSCC are often trivialised; however, there is a high-risk subgroup of cSCC (HRcSCC) that is associated with a high risk of metastasis and death.

Introduction: Cancer-related cognitive impairment is common among people diagnosed with and treated for cancer. This can be a distressing and disabling side effect for impacted individuals. Interventions to mitigate cognitive dysfunction are available, but, to date, most have been trialled in samples that are largely or exclusively composed of people with solid tumours.
