Dane particles-associated hepatitis B core antigen (HBcAg) was determined by radioimmunoassay in 61 patients with hepatitis B surface antigen (HGsAg)-positive chronic hepatitis. HBc antigenemia was observed in 61% of patients, especially in those with epidemiological risk factors. Patients with chronic active hepatitis as well as those with chronic persistent hepatitis may have HBc antigenemia. The highest levels of HBcAg were observed in male homosexuals. Follow-up determinations indicate the general tendency of HBcAg to decrease or disappear. HBcAg-positive patients with chronic active hepatitis had a poor prognosis, whereas HBcAg-negative patients frequently had a favorable clinical course of the disease (P less than 0.001). The assay of HBcAg in the serum of patients with HBsAg-positive chronic active hepatitis is a useful parameter with both clinical and epidemiological importance.

Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, USA.
Background: Low back pain (LBP) is a leading cause of years lived with disability. However, the association of non-chronic LBP with levels of daily physical activity (PA) remains poorly explored. This study investigated the association between previous and current non-chronic LBP with daily PA and compliance with PA recommendations in middle and older-aged adults.

Background: A new paradigm of hybrid working exists, with most office workers sharing their work between the office and home office environment. Working from home increases time spent or prolonged sitting, which is associated with an increased risk of chronic disease. Interventions to reduce sitting time, specifically designed for both the office and home-office environments, are required to address this growing public health issue.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease characterized by airway obstruction and inflammation. Non-typeable Haemophilus influenzae (NTHi) lung infections are common in COPD, promoting frequent exacerbations and accelerated lung function decline. The relationship with immune responses and NTHi are poorly understood.

Background: Neuregulin (NRG) family is involved in energy metabolism, among which NRG1 is a neuregulin proved to play a protective role in MAFLD cells. But the presice echanism has not been fully illustrated. This study aimed to investigate the role of NRG1 via the ERK/SIRT1 signaling in the pathogenesis of MAFLD.
