Post-Coronavirus Disease 2019 Pandemic Antimicrobial Resistance.

Background And Aim: Antimicrobial resistance (AMR) is a chronic issue of our Westernized society, mainly because of the uncontrolled and improper use of antimicrobials. The coronavirus disease 2019 (COVID-19) pandemic has triggered and expanded AMR diffusion all over the world, and its clinical and therapeutic features have changed. Thus, we aimed to review evidence from the literature on the definition and causative agents of AMR in the frame of the COVID-19 post-pandemic era.

Liver Damage and COVID-19: At Least a "Two-Hit" Story in Systematic Review.

COVID-19 pandemic waves have hit on our lives with pulmonary and, also, gastrointestinal symptoms. The latter also includes acute liver damage linked to direct SARS-CoV-2 action and/or drug-induced (DILI) in the frame of pre-existing chronic liver disease. We aimed to review literature data regarding liver damage during COVID-19.

The Use of Peppermint Oil in Gastroenterology.

Background: For decades, mint has been used worldwide for its relieving effects against gastrointestinal disturbances. Peppermint is a perennial herb common in Europe and North America. The active ingredient of peppermint oil is menthol and has various gastroenterological and non-gastroenterological uses, especially in the context of functional gastrointestinal disorders (FGIDs).

Nutritional Support in Acute Liver Failure.

Acute liver failure (ALF) presents with an acute abnormality of liver blood tests in an individual without underlying chronic liver disease. The clinical course leads to the development of coagulopathy and hepatic encephalopathy. The role of nutrition in its prevention and treatment remains uncertain.

Fecal Microbiota Transplantation in NAFLD Treatment.

: Gut microbiota is not only a taxonomic biologic ecosystem but is also involved in human intestinal and extra-intestinal functions such as immune system modulation, nutrient absorption and digestion, as well as metabolism regulation. The latter is strictly linked to non-alcoholic fatty liver disease (NAFLD) pathophysiology. : We reviewed the literature on the definition of gut microbiota, the concepts of "dysbiosis" and "eubiosis", their role in NAFLD pathogenesis, and the data on fecal microbiota transplantation (FMT) in these patients.

Farnesoid X Receptor, Bile Acid Metabolism, and Gut Microbiota.

Obesity, type 2 diabetes, and non-alcoholic fatty liver disease (NAFLD) are characterized by the concepts of lipo- and glucotoxicity. NAFLD is characterized by the accumulation of different lipidic species within the hepatocytes. Bile acids (BA), derived from cholesterol, and conjugated and stored in the gallbladder, help the absorption/processing of lipids, and modulate host inflammatory responses and gut microbiota (GM) composition.

The Apparent Asymmetrical Relationship Between Small Bowel Bacterial Overgrowth, Endotoxemia, and Liver Steatosis and Fibrosis in Cirrhotic and Non-Cirrhotic Patients: A Single-Center Pilot Study.

Introduction: Gut microbiota are a complex ecosystem harboring our intestine. They maintain human body equilibrium, while their derangement, namely, "dysbiosis", has been associated with several gastrointestinal diseases, such as liver steatosis (NAFLD) and liver cirrhosis. Small intestinal bacterial overgrowth (SIBO) is an example of dysbiosis of the upper gastrointestinal (GI) tract.

Zinc and gut microbiota in health and gastrointestinal disease under the COVID-19 suggestion.

Microelements represent an emerging resource for medicine and its preventive branch. Zinc is the second most abundant element in our organism with peculiar physiologic functions and pathophysiologic implications in systemic and gastrointestinal (GI) diseases. It interacts very often with gut microbiota (GM) and can affect natural course of GI diseases through a bidirectional relationship with intestinal bugs.

From Pre- and Probiotics to Post-Biotics: A Narrative Review.

Background And Aims: gut microbiota (GM) is a complex ecosystem containing bacteria, viruses, fungi, and yeasts. It has several functions in the human body ranging from immunomodulation to metabolic. GM derangement is called dysbiosis and is involved in several host diseases.

Effects of enteral nutrition on patients with pressure lesions: a single center, pilot study.

Objective: Protein-energetic malnutrition (PEM) affects prognosis and mortality in elderly patients as an inadequate nutritional status is a risk factor for the development and worsening of pressure sores (PS). We aimed to evaluate the incidence of PEM in outpatients with PS and to study the impact of nutritional support on the stage of PS.

Patients And Methods: PS patients, divided in a group treated with artificial nutrition (group A) and those fed orally (group B) at home, were consecutively enrolled in the Integrated Home Care program of Ascoli Piceno between June and September 2015.

Impact of patients nutritional status on major surgery outcome.

Objective: Surgery is a major stress factor that activates several inflammatory and catabolic pathways in man. An appropriate nutritional status allows the body to react properly to this stressor and recover in a faster and more efficient manner. On the other hand, malnutrition is related to a worse surgery outcome and to a higher prevalence of comorbidities and mortality.

Problems related to the use of animals for therapeutic and care purposes. The Document of the National Committee for Bioethics.

The Italian Ministry of Health, in 2002, instructed the National Committee for Bioethics to carefully review and ultimately provide evidence for future legislative bills in various aspects. One such matter was that of the subject of "Pet Therapy", generically viewed as a "man-animal" relationship, with the purpose of proving beneficiary to both human health and welfare. The necessity of a bioethical approach was deemed important in establishing the concrete benefits for mankind (and the research required to demonstrate this) whilst also considering any possible malaise inflicted on those animals participating.

[Autologous peripheral stem cell transplantation in a patient with diffuse systemic sclerosis: our experience].

The diffuse form of systemic sclerosis (SSc) can often lead to a rapidly progressive course with the involvement of the visceral organs which causes a severe prognosis. The 5-years cumulative mortality is between 30 and 60%, depending on the clinic form at the onset. Until now, no drug treatment has been proved to be efficacious against the progression of the disease or the regression of the fibrosis.

[Graves-Basedow disease associated with unusual variation of thyroid papillary carcinoma: a clinical case].

The authors describe a case of papillary carcinoma of the thyroid in a young patient with Graves-Basedow disease, diagnosed 10 years ago and now in long-term remission. Remission was achieved after many cycles of methimazole treatment for recurrent hyperthyroid disease. Clinical symptoms, characterized by pain and nodular swelling in the region of the left thyroid, did not improve after glucocorticoid treatment.

[The pulmonary cavitary lesion: a clinical case].

The authors describe a case of hydatid cystic disease presenting as a pulmonary excavation lesion. The peculiarity of this case consisted in the absence of the typical clinical symptoms caused by echinococcal cyst rupture into the bronchial cavity, e.g.

[Immuno-hemolytic anemia associated with lisinopril therapy. Report of a case].

The Authors describe a case of immuno-hemolytic anemia in a 67-year-old woman with hypertension who had been treated irregularly with lisinopril for three months. The hemolytic crisis resolved promptly after withdrawal of lisinopril and did not recur under high-dose methylprednisolone therapy.

[An unusual case of regular menstrual cycles and endocrine pattern typical for the reproductive age in a patient of advanced age].

The Authors report the persistence of regular menses in a very old woman. Although in the absence of a pulsatile gonadotropin pattern the patient showed estradiol levels typical of the reproductive age.

Effect of estrogens and progesterone on gonadotropin and prolactin release in a patient with androgen insensitivity.

Response of serum levels of gonadotropins and prolactin to doses of estrogen and progesterone was measured in a patient with the complete form of androgen insensitivity, ie, testicular feminization. Before gonadectomy a single 2.5-mg dose of estradiol benzoate (E2B) produced a decrease in gonadotropin levels.

Progesterone positive feedback on gonadotropin release in estrogen-primed postmenopausal women: central nervous system and pituitary as possible sites of action.

To investigate the site and mode of action of progesterone in inducing gonadotropin release, the effects of catecholamine-depleting (methyldopa) or dopamine agonist (bromocriptine) drugs on progesterone positive feedback and the gonadotropin response to a centrally acting noradrenergic drug (clonidine) were evaluated in estrogen-primed postmenopausal women. Progesterone administration induced a significant rise in LH, FSH, and PRL serum levels in the control group. Bromocriptine administration was followed by a marked suppression of PRL release but did not modify the gonadotropin response to progesterone.

[Adrenergic control of pancreatic glucagon secretion].

In order to characterize the adrenergic control of pancreatic A cell, the effect on the glucagon secretion of three sympathomimetic substances (epinephrine, isoproterenol, phenylephrine) and two adrenergic blockers (propranolol and phentolamine) have been separately examined by the isolated perfused rat pancreas. The study was performed in basal state and during glucagon hypersecretion induced by arginine or glucopenia. Epinephrine and isoproterenol infusion determined a prompt an sustained glucagon release both in the basal state and during glucagon hypersecretion.

[A new model for the in vitro study of the entero-island of Langerhans axis].

A new in vitro pancreas-intestine model which makes it possible to study the physiopathology of the intero-insular axis in greater depth, as it eliminates interference from other system, is proposed. The model, which is composed of the rat pancreas, duodenum and the first 25 cm of the small intestine, conserves both the circulation and the in vivo anatomical reltionship intact. Experiments were designed to evaluate the effect of a drug-induced disaccharidase-activity block on insulin secretion.

[Typing of the alpha adrenergic receptors of pancreatic B cells. In vitro studies with the isolated and perfused rat pancreas].

Two groups of receptors, one which develops a stimulating effect (alpha 1), the other an inhibitory effect hae recently been isolated in the alpha adrenergic group. In order to type the B cell adrenergic receptor of the endocrine pancreas, which mediates the inhibitory action exerted by the catecholamines on insulin secretion, the release of this hormone was evaluated in the presence of five alpha simpathomimetic substances that have a decreasing degree of efficiency on the adrenergic alpha 2 receptor of the presynaptic sympathic nerve terminal. The order of potency with which the alpha agonists tested depressed IRI secretion is superimposable on that of their potency on the sympathetic nerve and alpha 2 receptor.
