US still has the worst, most expensive health care of any high-income country | Ars Technica

Americans spend an exorbitant amount of money on health care and have for years. As a country, the US spends more on health care than any other high-income country in the world—on the basis of both per-person costs and a share of gross domestic product. Yet, you wouldn’t know it from looking at major health metrics in years past; the US has relatively abysmal health. And, if anything, the COVID-19 pandemic only exacerbated the USContinue…

How cancer cells move and metastasize is influenced by the fluids surrounding them – understanding how tumors migrate can help stop their spread

Counterintuitively, cells move faster in thicker fluids. New research on breast cancer cells explains why, and reveals the role that fluid viscosity plays in metastasis.

Complications, Adverse Drug Events, High Costs, and Disparities in Multisystem Inflammatory Syndrome in Children vs COVID-19 – PubMed

In this cross-sectional study, MIS-C was more common and severe than previously reported, with more racial disparities in outcomes than were seen in patients with COVID-19. The findings of this study suggest that relying on mean outcomes for MIS-C from past studies can be misleading … Study Also Finds Underreporting of Severe Effects of COVID-19 in Children Multisystem inflammatory syndrome in children (MIS-C), a rare but serious condition that causes severe inflammation of multiple organContinue…

Rising Risks with COVID Reinfection | Harvard Magazine

The risk of hospitalization, organ damage, and death rises markedly with repeat COVID-19 infection. Assistant professor of medicine Amy Barczak shared a Nature study that used data from the Veteran’s Administration to assess the cumulative risk of post-infection effects in people with one, two, and three or more SARS-CoV-2 infections, as compared to noninfected controls. The data show a consistent pattern of increased likelihood of hospitalization, cardiovascular effects, clotting and other blood disorders, diabetes, fatigue, gastrointestinal distress,Continue…

Acute and postacute sequelae associated with SARS-CoV-2 reinfection | Nature Medicine

Compared to no reinfection, reinfection contributed additional risks of death (hazard ratio (HR) = 2.17, 95% confidence intervals (CI) 1.93–2.45), hospitalization (HR = 3.32, 95% CI 3.13–3.51) and sequelae including pulmonary, cardiovascular, hematological, diabetes, gastrointestinal, kidney, mental health, musculoskeletal and neurological disorders. The risks were evident regardless of vaccination status. The risks were most pronounced in the acute phase but persisted in the postacute phase at 6 months. Compared to noninfected controls, cumulative risks and burdens of repeat infectionContinue…

Many minorities still don’t participate in clinical trials, but changing the narrative can save lives

For the Black community, the clinical trials are reminders of the often negative intersection of ethics, race, and medicine that has led to distrust. It is rooted in a history of exploitation of, and experimentation on, African-Americans that ranges from the Tuskegee Syphilis Study to a 19th-century doctor experimenting with gynecological treatments on enslaved women without anesthetics.Now more than ever, with the high death rates among Black men and women, it’s time to change theContinue…

New Research: COVID-19 Vaccines Saved 20 Million Lives Worldwide in the First Year

COVID-19 vaccines reduced the potential global death toll during the pandemic by more than half in the year following their implementation, according to estimates from a mathematical modeling study published on June 23, 2022, in The Lancet Infectious Diseases.19.8 million out of a potential 31.4 million COVID-19 deaths were prevented worldwide in the first year of the vaccination program according to estimates based on excess deaths from 185 countries and territories.The researchers estimate that aContinue…

The risk of seizures and epilepsy is higher after COVID than after the flu – new research

In a new study, we’ve found that the risk of seizures or epilepsy following a COVID infection is significantly higher than after an influenza infection.We know that COVID is associated with psychiatric and neurological symptoms such as anxiety and difficulty with memory. Many early studies exploring the impact of COVID on the brain, however, focused on the immediate period after infection or had low patient numbers.To try to more definitively answer whether COVID is associatedContinue…

COVID-19 Vaccines Safe with Immune Checkpoint Inhibitors – NCI

The new study involved more than 400 people with cancer who were treated at Memorial Sloan Kettering Cancer Center (MSKCC). Each received an mRNA COVID-19 vaccine before or after treatment with a type of immunotherapy drug known as an immune checkpoint inhibitor.An analysis of the patients’ medical records revealed no evidence that mRNA COVID-19 vaccination had increased the type, frequency, or severity of immune-related side effectsExit Disclaimer, such as inflammation in the lungs or colon,Continue…

The Relationship between Physical Activity and Long COVID: A Cross-Sectional Study

The relationship between Long Covid (LC) symptoms and physical activity (PA) levels are unclear. In this cross-sectional study, we examined this association, and the advice that individuals with LC received on PA. Adults with LC were recruited via social media. The New Zealand physical activity questionnaire short form (NZPAQ-SF) was adapted to capture current and pre-COVID-19 PA levels and activities of daily living (ADLs). Participants reported how PA affected their symptoms, and what PA recommendationsContinue…
