Ethics in the provision of obstetric and gynecologic health care for non-binary and transgender individuals.

Transgender and non-binary individuals often face bias and a lack of awareness, knowledge, and sensitivity from healthcare professionals. This article aims to raise awareness of the concepts of medical ethics among OBGYNs, so they will be better able to approach complex ethical situations in a clear and structured way when providing obstetric and gynecologic health care for transgender and gender-diverse patients.

The ethics and practice of perinatal care at the limit of viability: FIGO recommendations.

An arbitrary gestational age limit of viability cannot be set, and in clinical practice the focus should be on a periviability interval-the so-called "gray zone" of prognostic uncertainty. For cases within this interval, the most appropriate decision-making process remains debatable and periviability has emerged as one of the greatest challenges in bioethics. Universally recognized ethical principles may be interpreted differently due to socioeconomic, cultural, and religious aspects.

Glacier recession alters stream water quality characteristics facilitating bloom formation in the benthic diatom Didymosphenia geminata.

Glaciers provide cold, turbid runoff to many mountain streams in the late summer and buffer against years with low snowfall. The input of glacial meltwater to streams maintains unique habitats and support a diversity of stream flora and fauna. In western Canada, glaciers are anticipated to retreat by 60-80% by the end of the century, and this retreat will invoke widespread changes in mountain ecosystems.
