Abstract
BACKGROUND Higher protein intakes may help reduce sarcopenia and facilitate recovery from illness and injury in older adults. However, high-protein diets (HPDs) including animal-sourced foods may negatively perturb the microbiota, and provision of probiotics and prebiotics may mitigate these effects. OBJECTIVE The aim of this study was to examine the effects of HPD, with and without a probiotic and/or prebiotic, on gut microbiota and wellness in older women. DESIGN We conducted an 18-week, double-blind, placebo-controlled, crossover study. PARTICIPANTS/SETTING Participants were healthy, older women (mean age±standard deviation=73.7±5.6 years; n=26) recruited from Florida. INTERVENTION Participants received a weight-maintenance HPD for 2-week periods and the following, in random order: HPD alone (1.5 to 2.2 g/kg/day protein); HPD plus multistrain probiotic formulation (1.54×109Bifidobacterium bifidum HA-132, 4.62×109Bifidobacterium breve HA-129, 4.62×109Bifidobacterium longum HA-135, 4.62×109Lactobacillus acidophilus HA-122, and 4.62×109Lactobacillus plantarum HA-119), HPD plus prebiotic (5.6 g inulin), and HPD plus synbiotic (probiotic plus inulin), separated by 2-week washouts. Stools were collected per period for quantitative polymerase chain reaction (strain recovery) and 16S ribosomal RNA gene amplicon sequencing analyses (microbiota profile). Measures of gastrointestinal and general wellness were assessed. MAIN OUTCOME MEASURES Microbiota composition and probiotic strain recovery were measured. STATISTICAL ANALYSES Microbiota composition was analyzed by Wilcoxon signed-rank test and t test. Secondary outcomes were analyzing using generalized linear mixed models. RESULTS The microbiota profile demonstrated relative stability with the HPD; representation of Lactobacillus, Lactococcus, and Streptococcus were enhanced, whereas butyrate producers, Roseburia and Anaerostipes, were suppressed. Lactococcus was suppressed with synbiotic vs other HPD periods. Recovery was confirmed for all probiotic strains. Indicators of wellness were unchanged, with the exception of a minimal increase in gastrointestinal distress with inulin. Fat-free mass increased from baseline to study end. CONCLUSIONS An HPD adhering to the recommended acceptable macronutrient distribution ranges maintains wellness in healthy older women and exerts minor perturbations to the microbiome profile, a group that may benefit from a higher protein intake.

Abstract
Background Probiotics may provide a benefit for adults with Prader‐Willi syndrome (PWS) experiencing constipation. The primary aim was to determine if Bifidobacterium animalis ssp. lactis B94 (B. lactis B94) improves stool frequency, with secondary aims of stool form and gastrointestinal symptoms. Exploratory aims included diet quality and fecal microbiota composition. Methods Following a 4‐week baseline, 25 adults with PWS were randomized to consume B. lactis B94 by capsule (15 billion) or placebo for 4 weeks, followed by 4‐week washout in a double‐blind, crossover design. Stool frequency and Bristol Stool Form (BSF) were assessed daily, and Gastrointestinal Symptom Rating Scale (GSRS) and dietary intake (7‐days food records), per period. Fecal microbiota per period was analyzed using 16S rRNA gene amplicon sequencing and taxa of interest by qPCR (n = 24). Results No adverse events were reported. Stool frequency at baseline (n = 25; 2.0 ± 0.1 stools/day), GSRS syndromes, and microbiota composition did not differ with the probiotic intervention overall; however, a delayed, carry‐over effect on BSF types 6 and 7 was seen. Diet quality by HEI‐2015 was 65.4 ± 8.5. Conclusion In adults with PWS, B. lactis B94 exhibited little effect on laxation over 4 weeks; however, further research is needed.

Abstract
Specific probiotic strains can alleviate the gastrointestinal (GI) symptoms and psychiatric comorbidities of irritable bowel syndrome (IBS). In this randomized, double-blind, placebo-controlled study, the efficacy of Lactobacillus paracasei HA-196 (L. paracasei) and Bifidobacterium longum R0175 (B. longum) in reducing the GI and psychological symptoms of IBS was evaluated in 251 adults with either constipation (IBS-C), diarrhea (IBS-D), or mixed-pattern (IBS-M). Following a 2-week run-in period, participants were randomized to one of three interventions: L. paracasei (n = 84), B. longum (n = 83) or placebo (n = 81). IBS symptoms, stool frequency and consistency and quality of life were assessed by questionnaires. The differences from baseline in the severity of IBS symptoms at 4 and 8 weeks were similar between groups. Participants in this study were classified, after randomization, into subtypes according to Rome III. Within the L. paracasei group, complete spontaneous and spontaneous bowel movement frequency increased in participants with IBS-C (n = 10) after 8 weeks of supplementation (both p < 0.05) and decreased in participants with IBS-D (n = 10, p = 0.013). Both L. paracasei and B. longum supplementation improved the quality of life in emotional well-being and social functioning compared with baseline (all p < 0.05). In conclusion, L. paracasei and B. longum may reduce GI symptom severity and improve the psychological well-being of individuals with certain IBS subtypes.

Abstract
In the absence of established best practice standards in the probiotic field for reducing the risk of bacterial transfer between experimental groups, we developed protocols and methods to ensure the highest quality and interpretability of results from animal studies, even when performed in non-conventional animal care facilities. We describe easily implementable methods for reducing cross-contamination during animal housing, behavioural testing, and euthanasia, along with highlighting protocols for contamination detection in experimental subjects and laboratory areas using qPCR. In light of the high cross-contamination risks between animals during experiments involving probiotics, constant vigilance in animal care and research protocols is critical to ensure valid and reliable research findings.

Abstract
An outbreak of a novel coronavirus disease-19 (nCoV-19) infection began in December 2019 in Wuhan, China, and now involved the whole word. Several health workers have been infected in different countries. We report the case of a young man with documented nCoV-19 infection evaluated with lung ultrasound and discuss potential applications of lung ultrasound in this setting. Lung ultrasound allowed the identification of nCoV-19 infection at bed-side. Moreover, lung ultrasound can have several other advantages, such as reduced health worker exposition to infected patients, repeatability during follow-up, low-costs and easier application in low-resource settings.

Abstract
A yeast culture grown in a nutrient-rich medium initially containing 2% glucose is not limited in calorie supply. When yeast cells cultured in this medium consume glucose, they undergo cell cycle arrest at a checkpoint in late G1 and differentiate into quiescent and non-quiescent cell populations. Studies of such differentiation have provided insights into mechanisms of yeast chronological aging under conditions of excessive calorie intake. Caloric restriction is an aging-delaying dietary intervention. Here, we assessed how caloric restriction influences the differentiation of chronologically aging yeast cultures into quiescent and non-quiescent cells, and how it affects their properties. We found that caloric restriction extends yeast chronological lifespan via a mechanism linking cellular aging to cell cycle regulation, maintenance of quiescence, entry into a non-quiescent state and survival in this state. Our findings suggest that caloric restriction delays yeast chronological aging by causing specific changes in the following: 1) a checkpoint in G1 for cell cycle arrest and entry into a quiescent state; 2) a growth phase in which high-density quiescent cells are committed to become low-density quiescent cells; 3) the differentiation of low-density quiescent cells into low-density non-quiescent cells; and 4) the conversion of high-density quiescent cells into high-density non-quiescent cells.

Abstract
We have previously revealed that exogenously added lithocholic bile acid (LCA) extends the chronological lifespan of the yeast Saccharomyces cerevisiae, accumulates in mitochondria and alters mitochondrial membrane lipidome. Here, we use quantitative mass spectrometry to show that LCA alters the age-related dynamics of changes in levels of many mitochondrial proteins, as well as numerous proteins in cellular locations outside of mitochondria. These proteins belong to 2 regulons, each modulated by a different mitochondrial dysfunction; we call them a partial mitochondrial dysfunction regulon and an oxidative stress regulon. We found that proteins constituting these regulons (1) can be divided into several "clusters", each of which denotes a distinct type of partial mitochondrial dysfunction that elicits a different signaling pathway mediated by a discrete set of transcription factors; (2) exhibit 3 different patterns of the age-related dynamics of changes in their cellular levels; and (3) are encoded by genes whose expression is regulated by the transcription factors Rtg1p/Rtg2p/Rtg3p, Sfp1p, Aft1p, Yap1p, Msn2p/Msn4p, Skn7p and Hog1p, each of which is essential for longevity extension by LCA. Our findings suggest that LCA-driven changes in mitochondrial lipidome alter mitochondrial proteome and functionality, thereby enabling mitochondria to operate as signaling organelles that orchestrate an establishment of an anti-aging transcriptional program for many longevity-defining nuclear genes. Based on these findings, we propose a model for how such LCA-driven changes early and late in life of chronologically aging yeast cause a stepwise development of an anti-aging cellular pattern and its maintenance throughout lifespan.

Abstract
An exposure of the yeast Saccharomyces cerevisiae to exogenous palmitoleic acid (POA) elicits "liponecrosis," a mode of programmed cell death (PCD) which differs from the currently known PCD subroutines. Here, we report the following mechanism for liponecrotic PCD. Exogenously added POA is incorporated into POA-containing phospholipids that then amass in the endoplasmic reticulum membrane, mitochondrial membranes and the plasma membrane. The buildup of the POA-containing phospholipids in the plasma membrane reduces the level of phosphatidylethanolamine in its extracellular leaflet, thereby increasing plasma membrane permeability for small molecules and committing yeast to liponecrotic PCD. The excessive accumulation of POA-containing phospholipids in mitochondrial membranes impairs mitochondrial functionality and causes the excessive production of reactive oxygen species in mitochondria. The resulting rise in cellular reactive oxygen species above a critical level contributes to the commitment of yeast to liponecrotic PCD by: (1) oxidatively damaging numerous cellular organelles, thereby triggering their massive macroautophagic degradation; and (2) oxidatively damaging various cellular proteins, thus impairing cellular proteostasis. Several cellular processes in yeast exposed to POA can protect cells from liponecrosis. They include: (1) POA oxidation in peroxisomes, which reduces the flow of POA into phospholipid synthesis pathways; (2) POA incorporation into neutral lipids, which prevents the excessive accumulation of POA-containing phospholipids in cellular membranes; (3) mitophagy, a selective macroautophagic degradation of dysfunctional mitochondria, which sustains a population of functional mitochondria needed for POA incorporation into neutral lipids; and (4) a degradation of damaged, dysfunctional and aggregated cytosolic proteins, which enables the maintenance of cellular proteostasis.

Abstract
Recent findings suggest that evolutionarily distant organisms share the key features of the aging process and exhibit similar mechanisms of its modulation by certain genetic, dietary and pharmacological interventions. The scope of this review is to analyze mechanisms that in the yeast Saccharomyces cerevisiae underlie: (1) the replicative and chronological modes of aging; (2) the convergence of these 2 modes of aging into a single aging process; (3) a programmed differentiation of aging cell communities in liquid media and on solid surfaces; and (4) longevity-defining responses of cells to some chemical compounds released to an ecosystem by other organisms populating it. Based on such analysis, we conclude that all these mechanisms are programs for upholding the long-term survival of the entire yeast population inhabiting an ecological niche; however, none of these mechanisms is a ʺprogram of agingʺ - i.e., a program for progressing through consecutive steps of the aging process.

Abstract
Age is the major risk factor in the incidence of cancer, a hyperplastic disease associated with aging. Here, we discuss the complex interplay between mechanisms underlying aging and cancer as a reciprocal relationship. This relationship progresses with organismal age, follows the history of cell proliferation and senescence, is driven by common or antagonistic causes underlying aging and cancer in an age-dependent fashion, and is maintained via age-related convergent and divergent mechanisms. We summarize our knowledge of these mechanisms, outline the most important unanswered questions and suggest directions for future research.

Abstract
A body of evidence supports the view that the signaling pathways governing
cellular aging - as well as mechanisms of their modulation by
longevity-extending genetic, dietary and pharmacological interventions - are
conserved across species. The scope of this review is to critically analyze
recent advances in our understanding of cell-autonomous mechanisms of
chronological aging in the budding yeast Saccharomyces
cerevisiae. Based on our analysis, we propose a concept of a
biomolecular network underlying the chronology of cellular aging in yeast. The
concept posits that such network progresses through a series of lifespan
checkpoints. At each of these checkpoints, the intracellular concentrations of
some key intermediates and products of certain metabolic pathways - as well as
the rates of coordinated flow of such metabolites within an intricate network of
intercompartmental communications - are monitored by some checkpoint-specific
ʺmaster regulatorʺ proteins. The concept envisions that a synergistic action of
these master regulator proteins at certain early-life and late-life checkpoints
modulates the rates and efficiencies of progression of such processes as cell
metabolism, growth, proliferation, stress resistance, macromolecular
homeostasis, survival and death. The concept predicts that, by modulating these
vital cellular processes throughout lifespan (i.e., prior to an arrest of cell
growth and division, and following such arrest), the checkpoint-specific master
regulator proteins orchestrate the development and maintenance of a pro- or
anti-aging cellular pattern and, thus, define longevity of chronologically aging
yeast.

Abstract
We identified a form of cell death called "liponecrosis." It can be elicited by an exposure of the yeast Saccharomyces cerevisiae to exogenous palmitoleic acid (POA). Our data imply that liponecrosis is: (1) a programmed, regulated form of cell death rather than an accidental, unregulated cellular process and (2) an age-related form of cell death. Cells committed to liponecrotic death: (1) do not exhibit features characteristic of apoptotic cell death; (2) do not display plasma membrane rupture, a hallmark of programmed necrotic cell death; (3) akin to cells committed to necrotic cell death, exhibit an increased permeability of the plasma membrane for propidium iodide; (4) do not display excessive cytoplasmic vacuolization, a hallmark of autophagic cell death; (5) akin to cells committed to autophagic death, exhibit a non-selective en masse degradation of cellular organelles and require the cytosolic serine/threonine protein kinase Atg1p for executing the death program; and (6) display a hallmark feature that has not been reported for any of the currently known cell death modalities-namely, an excessive accumulation of lipid droplets where non-esterified fatty acids (including POA) are deposited in the form of neutral lipids. We therefore concluded that liponecrotic cell death subroutine differs from the currently known subroutines of programmed cell death. Our data suggest a hypothesis that liponecrosis is a cell death module dynamically integrated into a so-called programmed cell death network, which also includes the apoptotic, necrotic, and autophagic modules of programmed cell death. Based on our findings, we propose a mechanism underlying liponecrosis.

Abstract
1116 Background: We conducted a multicenter randomized phase II trial to assess activity and tolerability of the combination of nonpegylated liposomal doxorubicin plus vinorelbine versus standard nonpegylated liposomal doxorubicin plus cyclophosphamide. Methods: This multicenter randomized phase II study was planned to enrol 140 patients (pts). Elegibile pts must have LABC or MBC, PS (ECOG) ≤ 2, and measurable disease. Adjuvant or neoadjuvant chemotherapy with anthracyclines was allowed as well as prior endocrine therapy. Pts assigned to arm A received nonpegylated liposomal doxorubicin 60 mg/m2 plus cyclophosphamide 600 mg/m2 on day 1 of a 21-day cycle. Pts assigned to arm B received nonpegylated liposomal doxorubicin 50 mg/m2 plus vinorelbine 25 mg/m2 iv on day 1, and 60 mg/m2 on day 8 po, every 3 weeks. The primary outcome measure was response rate (RR), whereas safety was one of the secondary endpoints. Results: Between July 2006 and July 2008 110 women were treated; for 80 of these, safety results are available. Patient characteristics: Arm A pts (N=41): median age, 59 (range 37–69); ER status ±/unk, 26/15/0; Her-2 status ±/unk, 5/34/2; PS 0/1/2, 26/14/1; prior adjuvant treatment with anthracyclines 10 pts (24%); dominant site of disease visceral 31 pts (76%). Arm B pts (N=39): median age, 61 (range 25–70); Er status ±/unk, 29/10/0; Her-2 status ±/unk, 3/35/1; prior adjuvant treatment with anthracyclines 14 pts (36%); dominant site of disease visceral in 28 pts (72%). There was no study discontinuation due to AE either in arm A or in arm B, nor study-related deaths. Conclusions: The combination regimen of nonpegylated liposomal doxorubicin plus vinorelbine appears to be associated with a slight increase of hematological and nonhematological toxicity when compared with nonpegylated liposomal doxorubicin plus cyclophosphamide. No increase in cardiotoxicity was seen. The trial is ongoing and we plan to give preliminary efficacy results at the time of the Meeting.

Abstract
In recent years, the introduction of targeted therapies into clinical practice seems to offer incremental benefits in the treatment of metastatic colorectal cancer (mCRC), mainly when they are employed in combination with optimal chemotherapy and/or radiotherapy. In this paper, we focus on Cetuximab and its role in the treatment of mCRC.

Abstract
19506 Background: GISTs represents 0.1–3% of gastrointestinal neoplasms; most cases occur in people 40 to 80 years old, and are more common in men than in women. More than half of all GISTs patients present with locally advanced, recurrent, or metastatic disease (mainly to liver or peritoneum). Methods: From January 2001 to December 2005 we observed in our Institution 26 pts with GISTs; all were CD117+.The main characteristics of these pts were as follows: median age: 61 yr; sex (F/M): 14/12; primary tumor site: stomach 13 (50 %), small intestine 7 (27 %), rectum 1 (4 %), retroperitoneum 4 (15 %), liver 1 (4 %); first symptoms: epigastric pain 10 (38 %); abdominal pain 4 (15 %); hematemesis 1 (3 %); anemia 5 (18,5 %), palpable abdominal mass 1 (3 %), defecation disorders 2 (7 %); melena 3 (11 %); rectal bleeding 1 (3 %); ascites 1 (3 %). Results: Radical surgical resection was performed in 21 patients (81 %), 2 patients received a debulking surgery, and no postoperative mortality or major complications were observed; 3 pts showed an advanced disease. Seven pts (33%) developed recurrence, local or at distance, and the median time to relapse was 7,5 months (range 2–11). One pt with advanced disease dead before any treatment and 11 pts received Imatinib (I), at the standard dose (400 mg/d), starting from the date of diagnosis of advanced disease or metastatic relapse and given until development of intolerance or progressive disease. Main toxicities of I included: neutropenia G3 (4%), skin rash (4%), periorbital oedema (4%). We achieved 3 PR (lasting 12+, 21+ and 40 mos), 6 SD and 2 PD. With a median follow-up of 30 months, all but three pts (dead for progressive diseases) are alive. The overall survival rate was 88.5 % and the median overall survival was 16 mos (range 1–49). Conclusions: Surgical resection remains the only effective treatment for GISTs. However, in pts with advanced or relapsed disease treatment with I is effective with an high disease control rate. No significant financial relationships to disclose.

Abstract
Thirty-six patients (pts) with unpretreated advanced non-small cell lung cancer (NSCLC) stages IIIB and IV were enrolled in this two-stage phase I-II study aimed to establish the maximum tolerated dose (MTD) of paclitaxel and to evaluate the efficacy and safety of paclitaxel combined with etoposide every 3 weeks for a maximum of 6 courses, increasing the dose of paclitaxel according to a modified Fibonacci scheme. Nineteen pts were enrolled in the first stage and 17 pts in the second stage. The characteristics of the pts were as follows: median age 56 years (40-70), median Karnofsky's Performance Status 80% (70-80), 11 pts were stage IIIB and 25 pts stage IV. The doses of etoposide administered were 50 mg/m2 for 15 pts and 100 mg/m2 for 21 pts. MTD has not been reached and the study proceeded with the dose of paclitaxel 250 mg/m2. We obtained 9 (25%) partial remissions (PR) and 11 (31%) stable disease (SD) in 33 objectively evaluable pts. Median time to progression (TTP) was 4 months (0.3-21), median survival was 9.3 months (0.3-27). The main toxicity was neutropenia and neurotoxicity, while the gastrointestinal toxicity was mild. Two pts deceased after the first course. The causes of death were necrotizing enteritis in the first pt and congestive heart failure in the second pt. A total of 156 courses were administered at 7 dose levels, with a median of 4 courses per patient (1-6). The results seem to support the use of this combination in advanced non-small cell lung cancer.

Abstract
OBJECTIVE To show the possible role of abdominal scintigraphy in the diagnosis of intra-abdominal pathology and its accuracy in detecting ectopic gastric mucosa in pts with intestinal bleeding and/or abdominal pain. METHOD 99m-Tc-pertechnetate scintigraphy was performed on 54 pts with a history of intestinal bleeding and/or abdominal pain with the following results: 11 true positive pts (9 with Meckel's D; 2 with enteric duplication) all of whom were confirmed at surgery; 14 false positive pts in whom the presence and location of entero-colic (12 pts), renal (2 pts), and uterine (1 pt) pathology were determined; 28 true negative pts; an arca of persistent low activity was found in the bladder of 1 pt which later proved to be a ureterocele at ultrasound; 1 false negative pt who was found to have Meckel's D at surgery. CONCLUSION In this case series abdominal scintigraphy was effective in diagnosing 26/54 pts and, in particular, in diagnosis, 23/28 pts in recurrent intestinal bleeding. Given that its sensitivity is not negligible and that it is an exam which is scarcely invasive, easy to perform and interpret and requires low irradiation (definitely lower than barium enemas, digestive tract radiography and CT), abdominal scintigraphy should be the first examination to be performed in all pts with intestinal bleeding and/or abdominal pain, especially children, whose diagnosis cannot be simply or rapidly determined.
