Dynamical analysis of SEIS model with nonlinear innate immunity and saturated treatment.

Eur Phys J Plus 2021 17;136(9):952. Epub 2021 Sep 17.

Department of Mathematics, University of Delhi, Delhi, 110007 India.

In this paper, we develop an SEIS model with Holling type II function representing the innate immunity as well as the saturated treatment. We obtain the existence and stability criteria for the equilibrium points. We observe that when the reproduction number is less than unity, the disease-free equilibrium always exists and is locally asymptotically stable. Read More

How physicians evaluate patients with dementia who present with shortness of breath.

J Am Geriatr Soc 2021 Sep 20. Epub 2021 Sep 20.

Center for the Study of Healthcare Innovation, Implementation, and Policy, VA Greater Los Angeles Healthcare System, Los Angeles, California, USA.

Background: Whether the presence of dementia in patients makes it difficult for physicians to assess the risk such patients might have for serious conditions such as pulmonary embolism (PE) is unknown. Our objective was to examine the differential association of four clinical factors (deep venous thrombosis (DVT)/PE, malignancy, recent surgery, and tachycardia) with PE testing for patients with dementia compared to patients without dementia.

Methods: We performed a cross-sectional study of emergency department (ED) visits to 104 Veterans Affairs (VA) hospitals from 2011 to 2018 by patients aged 60 years and over presenting with shortness of breath (SOB). Read More

Biopsy bacterial signature can predict patient tissue malignancy.

Sci Rep 2021 Sep 17;11(1):18535. Epub 2021 Sep 17.

Cancer [email protected], University College Cork, Cork, Ireland.

Considerable recent research has indicated the presence of bacteria in a variety of human tumours and matched normal tissue. Rather than focusing on further identification of bacteria within tumour samples, we reversed the hypothesis to query if establishing the bacterial profile of a tissue biopsy could reveal its histology / malignancy status. The aim of the present study was therefore to differentiate between malignant and non-malignant fresh breast biopsy specimens, collected specifically for this purpose, based on bacterial sequence data alone.

Cut-off points to screening for sarcopenia in community-dwelling older people residents in Brazil.

PeerJ 2021 25;9:e12038. Epub 2021 Aug 25.

Postgraduate Program in Physiotherapy, Federal University of Rio Grande do Norte, Natal, Rio Grande do Norte, Brazil.

Background: At a time when the world's population is aging, one of the most important challenges for the healthcare field is to control the decline of the musculoskeletal system. This decline consists of a reduction in muscle mass and function, which is called sarcopenia and is associated with adverse health outcomes. Although there has been an increase in the number of publications on sarcopenia and its consequences, the reported prevalence varies widely, since these depend on the characteristics of the population studied, the definitions found in the literature and the cut-off points adopted.

Instituto de Biofísica Carlos Chagas Filho, Universidade Federal do Rio de Janeiro, Rio de Janeiro, 21941-900, Brazil.

Cryptococcosis is an opportunistic disease caused by the fungus Cryptococcus neoformans and Cryptococcus gattii. It starts as a pulmonary infection that can spread to other organs, such as the brain, leading to the most serious occurrence of the disease, meningoencephalitis. The humoral response has already been described in limiting the progression of cryptococcosis where the B-1 cell seems to be responsible for producing natural IgM antibodies, crucial for combating fungal infections.
