Role of Rutin in 5-Fluorouracil-Induced Intestinal Mucositis: Prevention of Histological Damage and Reduction of Inflammation and Oxidative Stress.

Intestinal mucositis, characterized by inflammatory and/or ulcerative processes in the gastrointestinal tract, occurs due to cellular and tissue damage following treatment with 5-fluorouracil (5-FU). Rutin (RUT), a natural flavonoid extracted from Dimorphandra gardneriana, exhibits antioxidant, anti-inflammatory, cytoprotective, and gastroprotective properties. However, the effect of RUT on inflammatory processes in the intestine, especially on mucositis promoted by antineoplastic agents, has not yet been reported. In this study, we investigated the role of RUT on 5-FU-induced experimental intestinal mucositis. Swiss mice were randomly divided into seven groups: Saline, 5-FU, RUT-50, RUT-100, RUT-200, Celecoxib (CLX), and CLX + RUT-200 groups. The mice were weighed daily. After treatment, the animals were euthanized and segments of the small intestine were collected to evaluate histopathological alterations (morphometric analysis); malondialdehyde (MDA), myeloperoxidase (MPO), and glutathione (GSH) concentrations; mast and goblet cell counts; and cyclooxygenase-2 (COX-2) activity, as well as to perform immunohistochemical analyses. RUT treatment (200 mg/kg) prevented 5-FU-induced histopathological changes and reduced oxidative stress by decreasing MDA concentrations and increasing GSH concentrations. RUT attenuated the inflammatory response by decreasing MPO activity, intestinal mastocytosis, and COX-2 expression. These results suggest that the COX-2 pathway is one of the underlying protective mechanisms of RUT against 5-FU-induced intestinal mucositis.

When basic supplies are missing, what to do? Specific demands of the local street population in times of coronavirus - a concern of social psychiatry.

BACKGROUND: Homeless experts and some federal housing officials are sounding the alarm that the patchwork of government efforts to address the coronavirus outbreak risks leaving out one group of acutely vulnerable people: the homeless. In terms of isolation, it is too unclear what that looks like if you normally sleep on the streets. In this tough moment, when people should be turned away, not only it feels inhumane, but it is also a big public health risk, because where are they going to go? METHOD: The studies were identified using large-sized newspapers with international circulation RESULTS: With more cities suspecting community transmission of the novel coronavirus, people who sleep in shelters or hunker down outside already have a lower life expectancy and often have underlying health conditions that put them at greater risk if they develop COVID-19 (Global News, 2020). These people face lack of sleep, malnutrition, and "extreme stress levels just to meet their daily needs", all of which weakens the immune system. Along with mental illness or substance abuse disorders, they are "incredibly vulnerable to this virus". CONCLUSIONS: Health organizations are well aware of the risks involved in mental health. A large population of homeless people experience their pain and psychological distress intermittently. For low-income patients, the various borderline situations related to health/illness involve growing expectations regarding the basic needs. This is a serious concern when linked to the pandemic.

The emotional impact of Coronavirus 2019-nCoV (new Coronavirus disease).

BACKGROUND: A novel form of Coronavirus (2019-nCoV) in Wuhan has created a confused and rapidly evolving situation. In this situational framework, patients and front-line healthcare workers are vulnerable. METHOD: Studies were identified using large-circulation international journals found in two electronic databases: Scopus and Embase. RESULTS: Populations of patients that may require tailored interventions are older adults and international migrant workers. Older adults with psychiatric conditions may be experiencing further distress. The COVID-19 epidemic has underscored potential gaps in mental health services during emergencies. CONCLUSIONS: Most health professionals working in isolation units and hospitals do not receive any training for providing mental health care. Fear seems more certainly a consequence of mass quarantine.
