A new genus of springtail, Sernatropiella gen. nov., from Cundinamarca province, Colombia, was found at an altitude close to 3.000 m above sea level. It is the largest Neanuridae known in the Northern part of the South American Transition Zone. It is characterized by the presence of a strong hypertrichosis, five eyes per side, very small moruliform postantennal organ and a long buccal beak. Mouth parts very thin and slender. Body with paratergal areas different from other Pseudachorutinae of the region. Thorax and abdominal segments I and II with pre- and post-segmental tergites with setae, and most remarkable is the presence of pseudocelli on head, thorax and abdomen of the type species Sernatropiella pinzonae gen. et sp. nov. A new combination for Neotropiella malkini Arlé, 1981 as Sernatropiella malkini (Arlé, 1981) comb. nov. is given and is considered as a member of the new genus.

Morphological and morphometric investigations on testate amoebae from Mongolia with descriptions of a new genus and four new species.

Testate amoebae are a polyphyletic and highly diverse group of unicellular protists, inhabiting various habitats and successfully used as indicators of property of environmental variables, providing information on hydrology, pH and pollution of ecosystems. However, despite numerous studies, there is still a lack of data regarding their species diversity, geographical distribution and population dynamics in various habitats from previously unexplored or poorly investigated regions such as Mongolia. In this study, we describe the morphology and morphometry of a new genus and four new species: Armatura murmillo gen.

Older adults often experience multimorbidity, cognitive impairments, and physical frailties, increasing healthcare utilization and costs. Traditional medical approaches that focus on organ-specific diagnoses are insufficient for addressing these multifaceted needs.

This study validated these scales and explored factors that could improve their predictive accuracy among Japanese home health care patients.
Methods: This was a single-center retrospective cohort study.
Despite being increasingly adopted in various regions, the model of Hospital-at-home can still appear to be confusing to many healthcare workers. The authors examined and summarized the existing concepts and implementations of Hospital-at-home. How Hospital-at-home contrasts to traditional inpatient models were outlined.

Uropygi is an order of arachnids commonly known as vinegaroons or whip-scorpions. So far, two genera are known to occur in Brazil: Thelyphonellus Pocock, 1894 and Mastigoproctus Pocock, 1894. We examined the morphology of 182 specimens of Brazilian Mastigoproctus and sequenced 42 specimens for phylogenetic analyses, using mitochondrial and nuclear molecular markers.
