Falls at the interface between geriatric and psychiatric patients: a critical review from a psychopharmacological perspective.

Falls in the elderly represent one of the major clinical problems as they are serious events that often result in high residual disability and mortality rates. Knowledge on the subject derives mainly from geriatric and gerontopsychiatric research. However, gerontopsychiatric patients differ from geriatric patients not only for the psychiatric and neurological comorbidities, which are often not sufficiently taken into account in the scientific context, but also for the intake of psychotropic drugs, notoriously described as one of the main risk factors for falls.

Emergency Psychiatric Consultations During and After the COVID-19 Lockdown in Italy. A Multicentre Study.

The aim was to analyse the psychiatric consultations in nine Italian hospital emergency departments, by comparing the lockdown and post-lockdown periods of 2020 with the equivalent periods of 2019. Characteristics of psychiatric consultations, patients, and drug prescriptions were analyzed. Joinpoint models were used to identify changes in the weekly trend of consultations.

Probiotics Streptococcus salivarius 24SMB and Streptococcus oralis 89a interfere with biofilm formation of pathogens of the upper respiratory tract.

Bifidobacteria and lactobacilli in the gut microbiome of children with non-alcoholic fatty liver disease: which strains act as health players?

Introduction: Non-alcoholic fatty liver disease (NAFLD), considered the leading cause of chronic liver disease in children, can often progress from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH). It is clear that obesity is one of the main risk factors involved in NAFLD pathogenesis, even if specific mechanisms have yet to be elucidated. We investigated the distribution of intestinal bifidobacteria and lactobacilli in the stools of four groups of children: obese, obese with NAFL, obese with NASH, and healthy, age-matched controls (CTRLs).

Role of the Human Breast Milk-Associated Microbiota on the Newborns' Immune System: A Mini Review.

The human milk is fundamental for a correct development of newborns, as it is a source not only of vitamins and nutrients, but also of commensal bacteria. The microbiota associated to the human breast milk contributes to create the "initial" intestinal microbiota of infants, having also a pivotal role in modulating and influencing the newborns' immune system. Indeed, the transient gut microbiota is responsible for the initial change from an intrauterine Th2 prevailing response to a Th1/Th2 balanced one.

Impact of delivery mode on the colostrum microbiota composition.

Background: Breast milk is a rich nutrient with a temporally dynamic nature. In particular, numerous alterations in the nutritional, immunological and microbiological content occur during the transition from colostrum to mature milk. The objective of our study was to evaluate the potential impact of delivery mode on the microbiota of colostrum, at both the quantitative and qualitative levels (bacterial abundance and microbiota network).

A consumer's guide for probiotics: 10 golden rules for a correct use.

Probiotics are used all over the world as their beneficial effects on the human organism have been widely demonstrated. Certain probiotics can down-regulate production of pro-inflammatory cytokines and promote intestinal epithelial barrier functions, increasing an anti-inflammatory response and contributing to the host's overall health. The main mechanisms by which probiotic microorganisms can interact with the host are by modulating the immune system and the epithelial cell functions and interacting with intestinal gut microbiota.

In vitro comparison between α-tocopheryl acetate and α-tocopheryl phosphate against bacteria responsible of prosthetic and joint infections.

Biofilm-related infections represent a recurrent problem in the orthopaedic setting. In recent years, great interest was directed towards the identification of novel molecules capable to interfere with pathogens adhesion and biofilm formation on implant surfaces. In this study, two stable forms of α-tocopherol, the hydrophobic acetate ester and the water-soluble phosphate ester, were tested in vitro as coating for titanium prosthesis.

Reliability of a multiplex PCR system for diagnosis of early and late prosthetic joint infections before and after broth enrichment.

Early microbiological diagnosis of prosthetic joint infection (PJI) is essential for successful antimicrobial treatment; however, culture has limited sensitivity, particularly in patients who had received antibiotic therapy, and the utility of molecular methods for diagnosing PJIs remains debated. We investigated the reliability of a multiplex PCR system for the microbiological diagnosis of early and late PJIs. Samples of periprosthetic tissues, synovial fluid, and prosthetic implants from 47 patients with early (n=13) or late (n=34) PJI were analyzed by conventional culture and with the multiplex-PCR Unyvero ITI (U-ITI) cartridge system.

α-Defensin point-of-care test for diagnosis of prosthetic joint infections: neglected role of laboratory and clinical pathologists.

Periprosthetic joint infection (PJI) is a serious complication that may occur after native joint replacement leading to a severe health and economic burden. Currently, due to several confounding factors, PJI is difficult to diagnose. Today, a multidisciplinary approach is indispensable to correctly define a periprosthetic joint infection; indeed, tissue histology, microbiology cultures and clinical findings are used together to achieve this goal.

Effect of HN001 and BB536 on the healthy gut microbiota composition at phyla and species level: A preliminary study.

Aim: To evaluate the ability of HN001 and BB536 to colonize the intestinal environment of healthy subjects and modify the gut microbiota composition.

Methods: Twenty healthy Italian volunteers, eight males and twelve females, participated in the study. Ten subjects took a sachet containing 4 × 10 colony-forming units (CFU) of BB536 and 10 CFU of HN001, 30 min before breakfast (pre-prandial administration), while ten subjects took a sachet of probiotic product 30 min after breakfast (post-prandial administration).

Microbiota network and mathematic microbe mutualism in colostrum and mature milk collected in two different geographic areas: Italy versus Burundi.

Human milk is essential for the initial development of newborns, as it provides all nutrients and vitamins, such as vitamin D, and represents a great source of commensal bacteria. Here we explore the microbiota network of colostrum and mature milk of Italian and Burundian mothers using the auto contractive map (AutoCM), a new methodology based on artificial neural network (ANN) architecture. We were able to demonstrate the microbiota of human milk to be a dynamic, and complex, ecosystem with different bacterial networks among different populations containing diverse microbial hubs and central nodes, which change during the transition from colostrum to mature milk.

Ability of Lactobacillus kefiri LKF01 (DSM32079) to colonize the intestinal environment and modify the gut microbiota composition of healthy individuals.

Background: Probiotics have been observed to positively influence the host's health, but to date few data about the ability of probiotics to modify the gut microbiota composition exist.

Aims: To evaluate the ability of Lactobacillus kefiri LKF01 DSM32079 (LKEF) to colonize the intestinal environment of healthy subjects and modify the gut microbiota composition.

Methods: Twenty Italian healthy volunteers were randomized in pre-prandial and post-prandial groups.

Comparative evaluation of MicroDTTect device and flocked swabs in the diagnosis of prosthetic and orthopaedic infections.

The evolution of new prosthetic and osteosynthetic devices has led to more surgical indications, and this is accompanied by an increased incidence of septic complications in orthopaedic and trauma surgery in the general population. The strategy for choosing surgical or therapeutic (conservative) treatment is based on the identification of the pathogen: knowledge of the aetiological agents is an essential element in the decision-making process to ensure the most effective treatment is administered. The pathogen also needs to be considered in the challenging case of doubtful infection, where perhaps the only sign is inflammation, for a more accurate prediction of progression to either sepsis or healing.

Improving the Bacterial Recovery by Using Dithiothreitol with Aerobic and Anaerobic Broth in Biofilm-Related Prosthetic and Joint Infections.

Biofilm-related infections are serious complications in the orthopaedic prosthetic field and an accurate, quick microbiological diagnosis is required to set up a specific antimicrobial therapy. It is well known that the diagnosis of these infections remains difficult due to the bacterial embedding within the biofilm matrix on the implant surfaces. Recently, the use of DL-dithiothreitol (DTT) has been proved effective in biofilm detachment from orthopaedic devices.

Persisting changes of intestinal microbiota after bowel lavage and colonoscopy.

Objective: An adequate bowel preparation is essential for a successful colonoscopy, but to date, only scarce information exists on the impact of the bowel cleansing on the gut microbiota, in particular, 1 month after the procedure.

Patients And Methods: Through 16S rDNA Ion Torrent profiling of fecal samples of 10 patients, we evaluated changes that occurred in the gut microbiota composition immediately after a 4 liter polyethylene glycol-based (SELG Esse) bowel lavage and 1 month thereafter. We studied the gut microbiota at the phylum, class, and family level.

How to Study Biofilms after Microbial Colonization of Materials Used in Orthopaedic Implants.

Over the years, various techniques have been proposed for the quantitative evaluation of microbial biofilms. Spectrophotometry after crystal violet staining is a widespread method for biofilm evaluation, but several data indicate that it does not guarantee a good specificity, although it is rather easy to use and cost saving. Confocal laser microscopy is one of the most sensitive and specific tools to study biofilms, and it is largely used for research.
