Reactive oxygen species from neutrophils tied to severe COVID-19, sepsis
In patients with severe COVID-19 or sepsis, high levels of neutrophils seem to be able to generate reactive oxygen species (ROS), which might contribute to disease pathology, a recent study has found.

Five-test universal HBV screening strategy most cost-effective in China
A nationally representative study led by researchers from the University of Hong Kong and Xi’an Jiaotong University Health Science Centre, China, has shown that a five-test (ie, serum HBsAg/HBsAb/HBeAg/HBeAb/HBcAb) universal screening strategy in people aged 18–70 years is the most cost-effective hepatitis B virus (HBV) screening option in China.

Antibody responses to COVID-19 vaccines in older people: Recent evidence & local data
Older adults have weaker antibody responses to two doses of COVID-19 vaccines [ie, mRNA-based BNT162b2 vaccine and inactivated CZ02 vaccine] vs younger individuals, but a booster dose mounts SARS-CoV-2 neutralization activities to a high level, according to data presented at AIM 2022.

Comorbidities affect immune response to severe COVID-19
Immune signatures developed in response to severe COVID-19 appear to vary not only according to the principal disease but also with underlying comorbidities, such as hypertension, diabetes, and heart diseases, a new study has found.

Can vitamin D prevent severe COVID-19 outcomes in older people?
Vitamin D deficiency is common in modern society, particularly among older people who are homebound. Vitamin D supplements in older people may have a role in preventing serious complications of COVID-19, according to data presented at AIM 2022.

HBcrAg, HBsAb levels tied to persistent functional chronic hepatitis B cure
In chronic hepatitis B (CHB) patients treated with pegylated interferon alpha (peg-IFN-α)-based interventions, lower levels of the HB core-related antigen (HBcrAg) and higher levels of the HB surface antibody (HbsAb) are associated with durable functional cure, a recent study has found,

How effective were oral antivirals during HK’s Omicron BA.2 wave?
A real-world study during Hong Kong’s Omicron BA.2 wave showed that both molnupiravir and nirmatrelvir/ritonavir effectively lowered the risks of disease progression and all-cause mortality in hospitalized COVID-19 patients not requiring oxygen supplementation on admission. However, mortality risk reduction was larger with nirmatrelvir/ritonavir vs molnupiravir.
