The pathophysiology of dysphagia post-lung transplant: A systematic review.

Laryngoscope Investig Otolaryngol

October 2024

Department of Speech, Language, and Hearing Sciences Universidad de Chile Santiago Chile.

Article Synopsis
  • The systematic review investigates the issue of oropharyngeal dysphagia in patients who have undergone lung transplantation, identifying instrumental assessment methods to characterize this complication.
  • A thorough literature search found 883 studies, but only six met the criteria for inclusion, primarily focusing on retrospective data regarding swallowing difficulties post-transplant.
  • Key findings highlight inconsistencies in evaluating dysphagia severity across studies, particularly in the use of the Penetration-Aspiration Scale, with aspiration rates varying significantly among patients.

Article Synopsis
  • Speciation is complex, involving various dimensions like ecology, genetics, and phenotypic traits, and is often studied through phylogeographic methods.* -
  • In certain cases, isolating lineages can create distinct species, while in others, gene flow occurs across environments, leading to regions where hybridization and genetic differences persist.* -
  • By examining eight pairs of North American snakes, the study identifies twelve clear species and explains how local adaptations and gene flow dynamics shape species diverging and interacting over time.*

Introduction: Past Alzheimer's disease and related dementias (ADRD) research has not considered ways to ensure the representation of diverse sexual and gender minorities. This study used concept mapping (CM) to identify strategies for engaging and recruiting LGBTQIA+ older adults living with memory loss and their caregivers into ADRD research.

Methods: CM, involving brainstorming, thematic analysis, and rating of strategies, was conducted with 46 members from one national and three local community advisory boards.

A new species of (Serpentes, Dipsadidae) from central Panama.

Zookeys

February 2023

Biodiversity Field Lab (BioFL), Khamai Foundation, Quito, Ecuador Biodiversity Field Lab (BioFL), Khamai Foundation Quito Ecuador.

A new species of Laurenti, 1768, from Central Panama is described based on molecular analyses, hemipenial morphology, and external characters. This is the sixth species of to be described for the country; the snake has been suspected to exist since 1977 and has not been thoroughly studied until now. Additionally, morphological comparations including scale counts are done with other species within the genus, and the current geographic distribution of (Werner, 1909), the sister species, is updated.

Transparent microelectrodes have emerged as promising tools to combine electrical and optical sensing and modulation modalities in many areas of biological and biomedical research. Compared to conventional opaque microelectrodes, they offer a number of specific advantages that can enable advances in functionality and performance. In addition to optical transparency, the mechanical softness feature is desired to minimize foreign body responses, increase biocompatibility, and avoid loss of functionality.

Article Synopsis
  • A single specimen of a previously unreported species was discovered in 2020 during SCUBA diving at 75 m depth around Jejudo Island, Korea.
  • The specimen's morphology matches closely with the holotype, notably featuring a distinct tubercle on the eyestalk and fusiform setae on the second pereiopod.
  • This research adds to existing knowledge by providing color photographs and an illustrated description of the species, highlighting previously unreported traits.

Background: The scale and duration of the COVID-19 pandemic posed a threat to provide the required support needed by emergency medicine (EM) trainees in India participating in the masters in EM program, a global partnership between the Ronald Reagan Institute for Emergency Medicine at the George Washington University and 14 institutions in India. While some of this support has been filled by remote education through thrice-weekly online video conferencing and webinars, the gap in procedural teaching posed a different challenge.

Methods: We developed a two-part innovation to teach suture skills, a required procedure for EM trainees.

Higher education faculty worldwide experienced heightened stressors due to the COVID-19 pandemic, from completing their professional roles and responsibilities virtually to balancing personal and professional stressors. Consequently, the pandemic created many adjustments for pre-tenure counseling faculty across research, teaching, and service. In response to this pandemic, we explored the impact of the COVID-19 pandemic on the personal and professional lives of four pre-tenure counseling faculty members.

Although past research has found that professional isolation can affect discernible work-related outcomes (e.g. job performance and turnover) and important job attitudes, researchers have not examined its impact on those less discernible but still costly work behaviours.

The COVID-19 pandemic has had an unprecedented psychological impact, revealing immense emotional disturbances among the general population. This study examined the extent to which social connectedness, dispositional mindfulness, and coping moderate symptoms of anxiety and depression in 1242 adults under the same government-issued COVID-19 stay-at-home mandate. Participants completed measures of anxiety, depression, dispositional mindfulness, social connectedness, and coping, and regression analyses were used to examine associations and interaction effects.

Empirical and philosophical problems with the subspecies rank.

Ecol Evol

July 2022

Department of Vertebrate Zoology Smithsonian Institution, National Museum of Natural History Washington District of Columbia USA.

Species-level taxonomy derives from empirical sources (data and techniques) that assess the existence of spatiotemporal evolutionary lineages via various species "concepts." These concepts determine if observed lineages are independent given a particular methodology and ontology, which relates the metaphysical species concept to what "kind" of thing a species is in reality. Often, species concepts fail to link epistemology back to ontology.

Improvement in Long-COVID Symptoms Using Acupuncture: A Case Study.

Med Acupunct

June 2022

Research Healthcare Group, VA Long Beach Healthcare System, Long Beach, California, USA.

Background: The long-COVID syndrome (LCS), defined by residual symptoms from acute COVID-19 for <60 days, affects about one-third of all COVID survivors and is an emerging public health challenge. Empirical data about the range of symptoms or the utility of acupuncture alone for the LCS are very limited.

Case: This observational case study of a 46-year-old male with LCS was conducted to preliminarily define the range of symptoms, a Traditional Chinese Medicine (TCM) diagnostic structure, and evaluate the potential utility of prescribed acupuncture for LCS.

Dusky Salamanders (genus ) currently comprise only 22 described, extant species. However, recent mitochondrial and nuclear estimates indicate the presence of up to 49 candidate species based on ecogeographic sampling. Previous studies also suggest a complex history of hybridization between these lineages.

Both the maternal and fetal outcomes of pregnancy vary greatly according to a pregnant woman's community and her condition. The most devastating outcome is the death of a mother. In 2017, there were ≈295,000 maternal deaths globally with dramatic differences in maternal mortality based on geographic region, country, and women's underlying conditions.

Improving the efficacy and spatial targeting of radiation therapy while sparing surrounding normal tissues has been a guiding principle for its use in cancer therapy. Nanotechnologies have shown considerable growth in terms of innovation and the development of new therapeutic approaches, particularly as radiosensitizers. The aim of this study was to systematically review how nanoparticles (NPs) are used to enhance the radiotherapeutic effect, including preclinical and clinical studies.

Article Synopsis
  • Chronic hepatitis C virus infection, alcohol use, smoking, and obesity increase the risk of hepatocellular carcinoma (HCC), but genetic factors also play a role; a genome-wide association study (GWAS) investigated this.
  • The study involved analyzing DNA from 705 HCC patients and 1455 control participants using over 710,000 SNPs, identifying significant genetic associations with HCC.
  • Two specific SNPs in chromosome 22q13.31 were consistently linked to HCC risk, and their association was validated in additional studies, highlighting potential genetic mechanisms that need further exploration.
