(Press-News.org) DENVER — Clinicians and researchers at National Jewish Health studied COVID vaccine effectiveness in patients with underlying lung conditions such as asthma, chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD). Findings show that nearly half of respiratory patients have lower vaccine-specific antibody, B cell, and T cell responses compared to healthy individuals. Decreased immunity to the vaccine suggests that patients with underlying lung conditions may be less protected against COVID-19. Understanding why they aren’t responding can give doctors a chance to treat patients differently.
“Most of the studies for the COVID vaccine have focused on how well the vaccine protects healthy people,” said R. Lee Reinhardt, PhD, Associate Professor in the Department of Immunology and Genomic Medicine and senior author of the study recently published in the European Respiratory Journal-Open Research. “There is not a lot of data available to know if it protects people with respiratory conditions the same way.”
Researchers studied the antibody, B-cell and T-cell responses in patients with respiratory conditions compared to healthy controls using samples from patients participating in the National Jewish Health Biobank research database. From blood samples, investigators measured vaccine-specific serum antibody, B cell and T cell levels, as well as their function. All parameters showed that patients with lung disease were significantly more likely to generate a poor vaccine response than their healthy counterparts.
“If these patients with lung conditions have fewer antibodies, their pulmonologists may have to design a more personalized vaccine approach,” said Haolin Liu, PhD, Assistant Professor in the Department of Immunology and Genomic Medicine and first author on the study. “They are more susceptible to exposure and can have their vaccine schedule adjusted.”
“COVID-19 is still around, and we don’t know what the future holds,” said Dr. Reinhardt. “There could be a winter surge and we need to understand how the immune response effects everyone – not just healthy people.”

Humans can make abstract choices independent of motor actions, but in lab tasks, choices are typically reported with an associated action

Humans can make abstract choices independent of motor actions, but in lab tasks, choices are typically reported with an associated action; this study shows that the human brain encodes perceptual choices independently of the specific motor actions used to implement them, even if such abstraction is not required by the task context.

Pennington Biomedical scientists continue to rank among the world’s most cited researchers
2023-10-10
BATON ROUGE – Five Pennington Biomedical Research Center faculty members and one adjunct professor rank among the most cited researchers in the world, according to the Google Scholar Citations database.
The database shows 5,882 scholars across the world have an h-index at or above 100. The h-index is a gauge of productivity and the impact of published papers. The index takes into account the researcher’s total number of papers and how many times each was cited by other scholars. An h-index over 100 means that at least ...
UMass Amherst study finds gender differences in HIV stigma in the Dominican Republic
2023-10-10
In a University of Massachusetts Amherst study recently published in PLOS ONE, researchers explored and described gender differences in HIV-related stigma and social support among people living with HIV (PLHIV) experiencing food insecurity in the Dominican Republic.
“Men’s experience of stigma were subtler and women described outright rejection and instances of physical violence, including intimate partner violence,” says lead author and postdoctoral researcher Alane Celeste-Villalvir.
For people living with HIV, stigma associated with the disease continues to be a significant ...
Chinese government’s corporate subsidies have had little effect on firms’ productivity
2023-10-10
Over the past 15 years, the Chinese government has made significant efforts to promote innovation-driven growth through industrial policy and corporate subsidies. In a new study, researchers examined government subsidies to businesses in China to determine whether they are making firms more productive. The study found that China’s rising wave of subsidizing businesses has had limited effect on promoting the firms’ productivity.
The study, by researchers at Carnegie Mellon University (CMU) and ShanghaiTech University, appears in the Journal of Comparative Economics.

Syracuse paleoclimatologists use ancient sediment to explore future climate in Africa
2023-10-10
In September 2023, extreme rains struck South Africa’s Western Cape province, flooding villages and leaving a trail of destruction. The catastrophic devastation is just one recent example in a string of extreme weather events that are growing more common around the world. Fueled by rising sea surface temperatures from global warming, torrential storms are increasing both in frequency and magnitude. Concurrently, global warming is also producing the opposite effect in other instances, as a mega-drought recently threatened the water supply of Cape Town in southwestern Africa to the point where residents were at risk of running out of water. This one-two punch of weather extremes ...

Syphilis transmission in US higher among transgender women and Black gay and bisexual men, study finds
2023-10-10
Transgender women and Black gay and bisexual men in Chicago are nearly twice as likely to contract syphilis at some point in their lives as white gay men, according to a new study conducted by scientists at Northwestern University.
The study, “Syphilis prevalence, incidence, and demographic differences in a longitudinal study of young sexual and gender minority adults assigned male at birth,” is the first to examine syphilis over time among young sexual and gender minorities — a category which encompasses gay and bisexual men, trans women and non-binary individuals. They found meaningful demographic differences ...

Rice-engineered material can reconnect severed nerves
2023-10-10
HOUSTON – (Oct. 10, 2023) – Researchers have long recognized the therapeutic potential of using magnetoelectrics ⎯ materials that can turn magnetic fields into electric fields ⎯ to stimulate neural tissue in a minimally invasive way and help treat neurological disorders or nerve damage. The problem, however, is that neurons have a hard time responding to the shape and frequency of the electric signal resulting from this conversion.
