Introduction: Listeria monocytogenes shows a special attraction to infect the central nervous system and its meningeals coats. It affects newborn as well as elderly people, patients with deficiencies in their cellular immune systems, and healthy adults. It presents most commonly as an acute meningitis, although it can present itself as cerebritis, brain stem encephalitis (rhomboencephalitis), and exceptionally as myelitis.

Patients: We describe six clinical cases of neurolisterioris, five of which in healthy adults; we also describe the images and cerebrospinal fluid (CSF) findings,

Results: Three patients contracted acute meningitis, one of them meningoencephalitis, one cerebritis and the last one rhomboencephalitis. The CSF was turbid or slightly turbid with normal glycorrachia in three patients. The diagnosis was made in five through culture of CSF. The patient with the rhomboencephalitis had brain stem microabscesses in the brain magnetic resonance. All the patients had a good outcome under antibiotics treatment.

Conclusion: Neurolisteriosis has to be kept in mind as a feasible diagnosis not only in immunocompromised but also in newborn as well as elderly patients. It should also be taken into account in young healthy adults living in regions under poor sanitary conditions where there is no adequate control of food manufacturing.

Background: Whether medium-term increased water intake alone, or in combination with co-adjuvant nonexercise interventions aimed to expand blood volume (BV), improve the human cardiovascular phenotype and cardiorespiratory fitness remains unexplored.

Objectives: The purpose of this study was to determine the medium-term impact of increased (+40%) fluid (water) intake (IFI) or IFI plus head-up sleep (IFI + HUS) on BV and the cardiovascular phenotype in healthy individuals.

Methods: Healthy adults (n = 35, age 42 ± 18 years, 51% female) matched by sex, age, body composition, physical activity, and cardiorespiratory fitness were randomly allocated to IFI or IFI + HUS for 3 months.

Objective: This study examines the association between family economic decision-making power and survival outcomes among older adults.

Methods: Data were drawn from the China Longitudinal Healthy Longevity Survey (CLHLS) from 2005 to 2018. Family economic decision-making power was assessed based on participants' self-reported influence over household financial matters, categorized as: "making decisions on almost all household expenditures", "deciding on non-essential spending", "only deciding on personal expenditures", and "having no decision-making power over household spending".

Enhancing elderly health has become an important measure for coping with population ageing and building a healthy China. Among them, older adults living alone seem to suffer from greater loneliness and psychological stress. We analyzed data from the China Health and Retirement Longitudinal Study in 2015, 2018, and 2020, and carried out an empirical investigation into the impact of digital inclusion on the health of elderly individuals living alone, using two-way fixed effects models and two-stage least squares.
