Abstract
OBJECTIVE Global longitudinal strain (GLS) predicts major adverse events in ST-segment elevation myocardial infarction (STEMI) and aortic stenosis (AS). Different cut-off values and different end-points have been proposed for prognostic stratification. We aimed to verify whether a single GLS cut-off value can be used to identify increased risk of all-cause death in STEMI and AS. PATIENTS AND METHODS One-hundred- seventeen successfully treated first STEMI (age 63.8±12.5 yrs, 70% men) and 64 AS (age 80.3±6.9 yrs, 44% men) patients, undergoing echocardiography before discharge and before AS treatment, respectively, were retrospectively analyzed. GLS was analyzed, together with pulmonary artery systolic pressure (PASP), Killip class and Genereux stage. End-point was all-cause death at 6-month follow-up. RESULTS All-cause death occurred in 4 (3.4%) STEMI and 5 (7.8%) AS patients (p=ns). AS patients who died had GLS similar to died STEMI patients (9.7±2.1 vs. 11.3±1.7, p=ns). GLS cut-off ≤12% predicted death with 89% sensitivity and 70% specificity (AUC 0.84, p=0.001): STEMI and AS patients with GLS ≤12% had worse survival than STEMI and AS patients with GLS >12% (log-rank p=0.001). At multivariate Cox regression analysis, lower GLS values independently predicted death (HR 0.667, 95% CI 0.451-0.986, p=0.042), and the prediction model was improved when GLS was added to old age, significant comorbidities, PASP and Killip/Genereux stage (χ2 6.691 vs. 1.364, p=0.010). CONCLUSIONS Died patients with STEMI and AS show similar values of GLS. A unique cut-off value of GLS can reliably be used to stratify the risk of all-cause death at 6-month follow-up in both two clinical settings.

Abstract
BACKGROUND AND AIMS Microbial-derived bile acids can modulate host gene expression, and their faecal abundance is decreased in active inflammatory bowel disease [IBD]. We analysed the impact of endoscopic inflammation on microbial genes involved in bile acid biotransformation, and their interaction with host transcriptome in the intestinal mucosa of IBD patients. METHODS Endoscopic mucosal biopsies were collected from non-inflamed and inflamed terminal ileum, ascending and sigmoid colon of IBD patients. Prediction of imputed metagenome functional content from 16S rRNA profile and real-time quantitative polymerase chain reaction [qPCR] were utsed to assess microbial bile acid biotransformation gene abundance, and RNA-seq was used for host transcriptome analysis. Linear regression and partial Spearman correlation accounting for age, sex, and IBD type were used to assess the association between microbial genes, inflammation, and host transcriptomics in each biopsy location. A Bayesian network [BN] analysis was fitted to infer the direction of interactions between IBD traits and microbial and host genes. RESULTS The inferred microbial gene pathway involved in secondary bile acid biosynthesis [ko00121 pathway] was depleted in inflamed terminal ileum of IBD patients compared with non-inflamed tissue. In non-inflamed sigmoid colon, the relative abundance of bile acid-inducible [baiCD] microbial genes was positively correlated with the host Angiopoietin-like 4 [Angptl4] gene expression. The BN analysis suggests that the microbial baiCD gene abundance could affect Angptl4 expression, and this interaction appears to be lost in the presence of inflammation. CONCLUSIONS Endoscopic inflammation affects the abundance of crucial microbial bile acid-metabolising genes and their interaction with Angptl4 in intestinal mucosa of IBD patients.

Abstract
OBJECTIVE To study whether intratesticular (IT) administration of 2 sources of human umbilical cord perivascular cells (HUCPVC), rich and potent sources of mesenchymal stromal cells (MSC), before chemotherapy can prevent infertility in a mouse model. DESIGN Two control groups of CD1 male mice without busulfan (BUS) administration (untreated and IT media injection groups) were included. Experimental groups included IT administration of media, first trimester (FTM) HUCPVCs or term HUCPVCs (n = 5 each) injected 3 days before BUS treatment (20 mg/kg). All groups were included in a mating time course study over 6 months. SETTING Preclinical study in a fertility center research laboratory. PATIENTS Not applicable. INTERVENTION IT delivery of FTM or term HUCPVC before BUS treatment. MAIN OUTCOME MEASURES Pregnancies, litter sizes, and gross morphology of offspring were monitored. Caudal epididymal sperm concentration, motility, and progressive motility were assessed by computer-assisted sperm analysis. Spermatogenesis was also assessed histologically in testicular tissue sections. RESULTS FTM and term HUCPVC displayed an MSC-associated immunophenotype and expressed transcripts encoding paracrine factors known to regulate the testicular cell niche. IT administration of FTM and term HUCPVC before chemotherapy promoted the recovery of spermatogenesis and fertility compared with BUS-treated animals that received a media injection. Although the total number of pups sired over 6 months by males treated with FTM or term HUCPVC was reduced compared with untreated or media-injected controls, litter size and sperm parameters in fertile animals did not differ between control and cell-treated groups. CONCLUSION HUCPVC represent a promising source of MSC-based therapy to prevent gonadotoxic chemotherapeutic drug-induced infertility.

Abstract
Chemotherapies can cause germ cell depletion and gonadal failure. When injected post-chemotherapy, mesenchymal stromal cells (MSCs) from various sources have been shown to have regenerative effects in rodent models of chemotherapy-induced gonadal injury. Here, we evaluated two properties of a novel source of MSC, first trimester (FTM) human umbilical cord perivascular cells (HUCPVCs) (with increased regenerative potential compared to older sources), that may render them a promising candidate for chemotherapeutic gonadal injury prevention. Firstly, their ability to resist the cytotoxic effects of cyclophosphamide (CTX) in vitro, as compared to term HUCPVCs and bone marrow cells (BMSCs); and secondly, whether they prevent gonadal dysfunction if delivered prior to gonadotoxic therapy in vivo. BMSC, FTM HUCPVC, term HUCPVC, and control NTERA2 cells were treated with moderate (150 μmol/L) and high (300 μmol/L) doses of CTX in vitro. Viability, proliferative capacity, mesenchymal cell lineage markers and differentiation capacity, immunogenicity, and paracrine gene expression were assessed. CTX was administered to Wistar rats 2 days following an intra-ovarian injection of FTM HUCPVC. HUCPVC survival and ovarian follicle numbers were assessed using histological methods. We conclude that FTM HUCPVC maintain key regenerative properties following chemotherapy exposure and that pre-treatment with these cells may prevent CTX-induced ovarian damage in vivo. Therefore, HUCPVCs are promising candidates for fertility preservation.

Abstract
Spread of the novel coronavirus SARS-CoV-2 has resulted in a global pandemic that is affecting the health and economy of all World Health Organization [WHO] regions. Clinical and translational research activities have been affected drastically by this global catastrophe. In this document we provide a suggested roadmap for resuming gastrointestinal translational research activities, emphasising physical distancing and use of personal protective equipment. We discuss modes of virus transmission in enclosed environments [including clinical workplaces and laboratories] and potential risks of exposure in the endoscopy environment for research staff. The proposed guidelines should be considered in conjunction with local institutional and government guidelines so that translational research can be resumed as safely as possible.

Abstract
Abstract
Background
Global longitudinal strain (LS) is a sensitive marker of ischemic myocardial damage and predicts adverse left ventricular (LV) remodeling and outcome, independently of infarct size. In healthy subjects, regional LS increases from LV base to apex and enhances under physical or pharmacological stress, while in ST-elevation myocardial infarction (STEMI), response to dobutamine depends on transmurality of necrosis. It is known that coronary flow reserve during adenosine (ADN) is impaired both in ischemic and remote myocardium, but effect of ADN on strain reserve has never been investigated. Similarly, LS response to ADN in ischemic (iLS) and remote (rLS) myocardium and their relative contribution to LV function and remodeling are still unknown.
Methods
61 consecutive patients with first STEMI (26 anterior, 29 inferior, 6 lateral), treated by successful primary percutaneous coronary intervention (PCI) followed by PCI of non-culprit coronary arteries, underwent rest and stress ADN (140 mcg/kg/minutes in 90 seconds) echocardiography at discharge (7 ± 2 days after admission). LV end-diastolic volume indexed for body surface area (EDV), ejection fraction (EF) and wall motion score index (WMSI) were measured at rest, while GLS, iLS and rLS analysis was performed both at rest and during stress. Ischemic and remote myocardium was allocated, by standard LV segmentation, basing on the culprit coronary artery.
Results
Significant differences existed among anterior, inferior and lateral STEMI in median (iQr) EDV [52 (45-59) vs 45 (36-51) vs 48 (45–56) ml, respectively, p=.034 overall], EF [47 (37-58) vs 58 (53–61) vs 56 (46-60)%, respectively, p=.002 overall], WMSI [1.63 (1.38–2) vs 1.25 (1.19-1.47) vs 1.41 (1.30-1.75), respectively, p=.001 overall]. GLS differed among anterior, inferior and lateral STEMI both at rest [13.75 (11.63-16.1) vs 19.5 (17.15-22.4) vs 17.85 (17.02-19), respectively, p<.001 overall] and during ADN [14 (12.35-16.15) vs 19.5 (17.9–22.05) vs 15.95 (14.40-19.48), respectively, p<.001], but did not change within groups. No differences were found between rest and stress iLS in any group. Similarly, rLS remained unchanged in anterior and inferior STEMI, and impaired after ADN in lateral STEMI [15.90 (11.45-18) at stress vs 16.8 (15.25-19.2) at rest, p=.043]. Inferior STEMI showed better iLS than anterior STEMI both at rest [17 (15.1–19.9) vs 13.75 (11.46-16.92), respectively, p=.001] and during stress [16.2 (15–20.4) vs 14.42 (12.67-15.83), respectively, p=.001].
Conclusions
In the subacute phase of STEMI, GLS, iLS and rLS are heterogeneous and depend on infarct site. After ADN, there is no strain reserve in ischemic neither in remote myocardium. This may reflect regional differences in the response of microcirculation and myocardium to ischemia or may underlie pre-existing pathophysiological differences in the coronary circulation

Abstract
The gasotransmitters nitric oxide (NO), carbon monoxide (CO), and hydrogen sulphide (H2 S), long considered only toxicant, are produced in vivo during the catabolism of common biological molecules and are crucial for a large variety of physiological processes. Mounting evidence is emerging that in poikilotherm vertebrates, as in mammals, they modulate the basal performance of the heart and the response to stress challenges. In this review, we will focus on teleost fish and amphibians to highlight the evolutionary importance in vertebrates of the cardiac control elicited by NO, CO and H2 S, and the conservation of the intracellular cascades they activate. Although many gaps are still present due to discontinuous information, we will use examples obtained by studies from our and other laboratories to illustrate the complexity of the mechanisms that, by involving gasotransmitters, allow beat-to-beat, short-, medium- and long-term cardiac homoeostasis. By presenting the latest data, we will also provide a framework in which the peculiar morpho-functional arrangement of the teleost and amphibian heart can be considered as a reference tool to decipher cardiac regulatory networks which are difficult to explore using more conventional vertebrates, such as mammals.

Abstract
BACKGROUND AND AIMS MicroRNAs [miRNAs] have emerged as important regulators in inflammatory bowel disease [IBD]. This study investigated differential expression of miRNAs across clinical phenotypes in a well-characterized cohort of IBD patients and healthy controls [HCs]. METHODS A cohort of Crohn's disease [CD] and ulcerative colitis [UC] patients and HCs was prospectively accrued. Total RNA was extracted from peripheral blood mononuclear cells for all subjects. miRNA expression was measured using NanoString technologies. The subjects were stratified according to disease activity and location. Statistical significance was assessed per miRNA across outcomes and corrected for multiple testing. miRNA regulation of transcription of important results was confirmed in vitro by a dual luciferase reporter assay and autophagy function was evaluated using immunofluorescence imaging of LC3 puncta in HeLa cells. RESULTS In total, 120 subjects were enrolled. Seventy-four miRNAs were differentially expressed across CD, UC and HCs. Comparing quiescent CD [CDq] with HCs we found ten miRNAs upregulated in CDq. When comparing colonic CD [CCD] to UC, seven miRNAs were upregulated in CCD. The most differentially expressed miRNA in CCD vs UC was miR-874-3p, and we showed its possible utility as a biomarker of differential diagnosis. We showed miR-874-3p targets ATG16L1 and reduces its expression in vitro. An miR-874-3p mimic dysregulates autophagy by a reduction of LC3 in vitro. CONCLUSIONS We identified unique miRNA signatures expressed in distinct IBD phenotypes. These associations highlight pathways dysregulated by aberrant miRNA expression, revealing possible mechanisms underlying the pathophysiology of IBD, but also suggest a cluster of miRNAs as readily accessible biomarkers to aid in differential diagnosis.

Abstract
Spermatogonial Stem Cell (SSC) expansion in vitro remains a major challenge in efforts to preserve fertility among pubertal cancer survivor boys. The current study focused on innovative approaches to optimize SSC expansion. Six- to eight-week-old CD-1 murine testicular samples were harvested by mechanical and enzymatic digestion. Cell suspensions were incubated for differential plating (DP). After DP, we established two experiments comparing single vs. repetitive DP (S-DP and R-DP, respectively) until passage 2 (P2) completion. Each experiment included a set of cultures consisting of 5 floating-to-attached cell ratios (5, 10, 15, 20, and 25) and control cultures containing floating cells only. We found similar cell and colony count drops during P0 in both S- and R-DP. During P2, counts increased in S-DP in middle ratios (10, 15, and especially 20) relative to low and high ratios (5 and 25, respectively). Counts dropped extensively in R-DP after passage 2. The superiority of intermediate ratios was demonstrated by enrichment of GFRα1 by qPCR. The optimal ratio of 20 in S-DP contained significantly increased proportions of GFRα1-positive cells (25.8±5.8%) as measured by flow cytometry compared to after DP (1.9±0.7%, p<0.0001), as well as positive immunostaining for GFRα1 and UTF1, with rare Sox9-positive cells. This is the first report of the impact of initial floating-to-attached cell ratios on SSC proliferation in vitro. ABBREVIATIONS SSC: spermatogonial stem cells; DP: differential plating; NOA: non-obstructive azoospermia; MACS: magnetic-activated cells sorting; FACS: fluorescence-activated cells sorting.

Abstract
High DNA fragmentation index (DFI) may be associated with poor outcome after IVF. Our aim was to determine whether DFI impacts blastocyst quality or clinical outcome. This retrospective study included 134 couples who underwent 177 IVF-ICSI and pre-implantation genetic screening (PGS) cycles during January 1st, 2014—March 31st, 2016 and had documented previous DFI. Group 1 (DFI>30%) encompassed 25 couples who underwent 36 cycles; Group 2 (DFI 15–30%) included 45 couples and 57 cycles; group 3 (DFI<15%) included 64 couples and 83 cycles. Male partners within group 1 were older (45.1 compared to 40.6 and 38.3 years, respectively, p<0.05), had higher BMI (32.4 compared to 26.6 and 25.8 respectively, p<0.05) and lower sperm count and motility (46*106/ml and 35.5%, respectively) compared to groups 2 (61.8*106/ml and 46.6%, respectively) and 3 (75.8*106/ml and 55.1%, respectively, p<0.05). Female parameters including ovarian reserve and response and embryo development were similar. Total numbers of biopsied blastocysts were 116, 175 and 259 in groups 1, 2 and 3, respectively. PGS for 24 chromosomes revealed comparable euploidy rate of 46–50.4%, with a similar morphological classification. No significant differences were found regarding pregnancy rates or pregnancy loss. It seems that DFI doesn't correlate with blastocyst aneuploidy or morphological grading.

Abstract
OBJECTIVE To optimize culture conditions for human testicular somatic cells (TSCs) and spermatogonial stem cells. DESIGN Basic science study. SETTING Urology clinic and stem cell research laboratory. PATIENT(S) Eight human testicular samples. INTERVENTIONS(S) Testicular tissues were processed by mechanical and enzymatic digestion. Cell suspensions were subjected to differential plating (DP) after which floating cells (representing germ cells) were removed and attached cells (representing TSCs) were cultured for 2 passages (P0-P1) in StemPro-34- or DMEM-F12-based medium. Germ cell cultures were established in both media for 12 days. MAIN OUTCOME MEASURE(S) TSC cultures: proliferation doubling time (PDT), fluorescence-activated cell sorting for CD90, next-generation sequencing for 89 RNA transcripts, immunocytochemistry for TSC and germ cell markers, and conditioned media analysis; germ cell cultures: number of aggregates. RESULT(S) TSCs had significantly prolonged PDT in DMEM-F12 versus StemPro-34 (319.6 ± 275.8 h and 110.5 ± 68.3 h, respectively). The proportion of CD90-positive cells increased after P1 in StemPro-34 and DMEM-F12 (90.1 ± 10.8% and 76.5 ± 17.4%, respectively) versus after DP (66.3 ± 7%). Samples from both media after P1 clustered closely in the principle components analysis map whereas those after DP did not. After P1 in either medium, CD90-positive cells expressed TSC markers only, and fibroblast growth factor 2 and bone morphogenetic protein 4 were detected in conditioned medium. A higher number of germ cell aggregates formed in DMEM-F12 (59 ± 39 vs. 28 ± 17, respectively). CONCLUSION(S) Use of DMEM-F12 reduces TSC proliferation while preserving their unique characteristics, leading to improved germ cell aggregates formation compared with StemPro-34, the standard basal medium used in the majority of previous reports.

Abstract
Chromogranin A (CgA) is an acidic protein co-stored with catecholamines, hormones and neuropeptides in the secretory granules of endocrine, neuronal and other cell types (including cardiomyocytes). Proteolytic cleavage in the C terminus of CgA generates a 2.9kDa peptide named serpinin (Serp; Ala26Leu) that can be modified at its N terminus to form a pyroglutamate residue (pGlu-Serp). In the rat heart, both peptides increase contractility and relaxation through a β-adrenergic-like action mechanism. Accordingly, Serp and pGlu-Serp were proposed as novel myocardial sympatho-adrenergic modulators in mammals. On a comparative basis, here we report the actions of Serp and pGlu-Serp on myocardial contractility in three poikilotherm vertebrate species: the eel (Anguilla anguilla), the goldfish (Carassius auratus) and the frog (Rana esculenta). Using isolated working heart preparations, we show that pGlu-Serp reduces stroke volume in all species tested, while Serp reduces contractility in the frog heart, but is uneffective in eel and goldfish hearts. In the goldfish and frog hearts, pGlu-Serp activates the Nitric Oxide/cGMP pathway involving Endothelin-1 B receptors (frog) and β3 adrenergic receptors (goldfish). pGlu-Serp-treated hearts from goldfish and frog show increased cGMP content. Moreover, the exposure of the frog heart to pGlu-Serp is accompanied by an increased expression of activated eNOS and Akt. In conclusion, this first report showing that pGlu-Serp inhibits mechanical cardiac performance in teleost and amphibians supports an evolutionary role of the CgA system, and particularly its serpinin component, in the sympatho-adrenergic control of the vertebrate heart.

Abstract
The expansion of functional testicular biopsy-derived human spermatogonial stem cells (hSSC) ex-vivo may enable the restoration of fertility in pre-pubertal males having undergone gonadotoxic therapies or men with severe male factor infertility. Various somatic cells are known to regulate SSC homeostasis and spermatogenesis in the developing and adult testis. Prior attempts to recapitulate this niche demonstrated the requirement of feeder cells, such as endogenous testicular somatic cells, for germ cell expansion ex-vivo. However, this strategy has limitations for the expansion of hSSCs from tissue biopsies where spermatogenesis is absent or defective. Our aim was to evaluate first trimester human umbilical cord perivascular cells (FTM HUCPVCs), a novel source of mesenchymal stromal-like cells (MSCs), as potential human feeder cells for standardized hSSC expansion ex-vivo. Targeted RNA sequencing analysis demonstrated that CD90+ve FTM HUCPVCs expanded in vitro under germ cell culture conditions express a profile of targeted testicular-associated transcripts that is similar to cultured human CD90+ve testicular adherent cells (hTACs) and secrete LIF, FGF2 and BMP4, key growth factors known to regulate spermatogenesis. We also demonstrated that mitotically-inactivated FTM HUCPVCs support the expansion of mouse germ cells and putative SSCs ex-vivo, and that FTM HUCPVC transplantation promotes in vivo germ cell regeneration following mono-2- ethylhexyl phthalate (MEHP)-induced seminiferous tubule damage in a murine model, including a partial reconstitution of tubular cellular architecture and reestablishment of DAZL and acrosin+ve germ cell layers. Together, these data suggest that FTM HUCPVCs have phenotypical and functional properties that may support repair of the human testicular niche.

Abstract
The hypothalamic neuropeptide Nesfatin-1 is present in both mammals and teleosts in which it elicits anorexigenic effects. In mammals, Nesfatin-1 acts on the heart by inducing negative inotropism and lusitropism, and cardioprotection against ischemic damages. We evaluated whether in teleosts, Nesfatin-1 also influences cardiac performance. In the goldfish (Carassius auratus), mature, fully processed Nesfatin-1 was detected in brain, gills, intestine and skeletal muscle, but not in the cardiac ventricle. However, on the isolated and perfused working goldfish heart, exogenous Nesfatin-1 induced a positive inotropic effect, revealed by a dose-dependent increase of stroke volume (SV) and stroke work (SW). Positive inotropism was abolished by inhibition of adenylate cyclase (AC; MDL123330A) and cAMP-dependent kinase (PKA; KT5720), suggesting a cAMP/PKA-mediated pathway. This was confirmed by the increased cAMP concentrations revealed by ELISA on Nesfatin-1-treated hearts. Perfusion with Diltiazem, Thapsigargin and PD98059 showed the involvement of L-type calcium channels, SERCA2a pumps and ERK1/2, respectively. The role of ERK1/2 and phospholamban in Nesfatin-1-induced cardiostimulation was supported by Western blotting analysis. In conclusion, this is the first report showing that in teleosts, Nesfatin-1 potentiates mechanical cardiac performance, strongly supporting the evolutionary importance of the peptide in the control of the cardiac function of vertebrates.

Abstract
More than a decade has now passed since the birth of the first endangered species produced from an adult somatic cell reprogrammed by somatic cell nuclear transfer. At that time, advances made in domestic and laboratory animal species provided the necessary foundation for attempting cutting-edge technologies on threatened and endangered species. In addition to nuclear transfer, spermatogonial stem cell transplantation and induction of pluripotent stem cells have also been explored. Although many basic scientific questions have been answered and more than 30 wild species have been investigated, very few successes have been reported. The majority of studies document numerous obstacles that still need to be overcome to produce viable gametes or embryos for healthy offspring production. This chapter provides an overview of somatic cell and stem cell technologies in different taxa (mammals, fishes, birds, reptiles and amphibians) and evaluates the potential and impact of these approaches for animal species conservation.

Abstract
AIMS We sought to evaluate the determinants and the potential benefit of abciximab use in unselected patients with acute myocardial infarction treated with primary angioplasty. METHODS AND RESULTS Based on the AMI-Florence registry, we analyzed 461 consecutive acute myocardial infarction patients treated with primary angioplasty, 280 (61%) of whom received abciximab. For each patient, a propensity score indicating the likelihood of abciximab treatment was calculated. Compared to those not treated, patients treated with abciximab were at lower risk. At multivariate analysis, the direct admission to a hospital with angioplasty facilities significantly increased the probability of receiving abciximab (OR 1.99, 95% CI 1.30-3.03, p=.001), while older age (OR 0.97, 95% CI 0.95-0.98, p<.0001), non-anterior location (OR 0.58, 95% CI 0.38-0.88, p=.011) and Killip class >1 (OR 0.53, 95% CI 0.32-0.87, p=.013), were negative predictors of abciximab use. Primary angioplasty had a higher success rate in patients treated with abciximab (99.3% versus 96.5%, p=.03). In-hospital and 1-year mortality were significantly lower in patients treated with abciximab (2.5% versus 13.3%, p<.0001, and 7% versus 21%, p<.0001, respectively). At multivariate analysis patients treated with abciximab had a significantly lower risk of in-hospital mortality (OR 0.35, 95% CI 0.14-0.93, p=.035), and a marginally lower risk of death at 1-year follow-up (HR 0.58, 95% CI 0.32-1.03, p=.065). These results did not change when the propensity score was included into the analyses. CONCLUSIONS In the real practice, abciximab is more frequently used in patients at lower risk, particularly when directly admitted to a hospital with angioplasty facilities. Abciximab use is associated with a significant reduction in early mortality. A trend toward a reduced mortality is maintained also at 1 year.

Abstract
OBJECTIVE To evaluate the effect of a subacute administration of oligomineral water "S. Croce Sponga" in subjects affected by chronic constipation. PATIENTS AND METHODS Hospitalized patients (13 females and 4 males) have been classified according to radiologically evaluated transit times if affected by colonic or rectal constipation, and by clinical interview if suffering from chronic colonic constipation due to increased resistance or hypomotility. Treatment consisted in the administration of 1.5 litres/day of S. Croce Sponga oligomineral water for 7 days or a control water of known composition. The study started after seven days of hospital stay. RESULTS The results of the study showed that S. Croce Sponga oligomineral water was effective in resolving the condition of chronic colonic constipation in almost 80% of the subjects. No effect was observed in subjects with chronic rectal constipation. CONCLUSIONS Treatment with S. Croce Sponga oligomineral water resolved chronic colonic constipation by enhancing velocity of the colonic transit.

Abstract
OBJECTIVE To determine whether reducing the speed of injection is effective in reducing injection pain for buffered and unbuffered lidocaine solutions. METHODS A prospective, single-blind, randomized, crossover, laboratory study was performed. Adult volunteers were recruited from ED staff at an urban teaching hospital to serve as subjects. Twenty-nine subjects each received 4 1-mL injections into the dorsum of the hands. Each subject received fast and slow injections of buffered and unbuffered lidocaine. Subjects rated the pain of each injection on a 100-mm visual analog scale (VAS). Mean pain scores for each intervention were compared using analysis of variance. RESULTS The mean pain VAS score for fast injection of buffered lidocaine was 14.1 mm. For slow buffered injection, the mean pain score was 11.4 mm (p = 0.98). For unbuffered lidocaine, the means were 28.7 mm for fast injection and 22.2 mm for slow injection (p = 0.40). CONCLUSIONS Reducing injection speed did not produce a statistically significant change in injection pain for either buffered or unbuffered solutions.

Abstract
To evaluate the ability of cine magnetic resonance imaging (cine MRI) in the assessment of mitral stenosis (MS), we studied 20 patients (14 women and 6 men, mean age 60.6 +/- 8.5 years) with rheumatic mitral valve stenosis by using an 0.5 T magnet. Cine MRI showed several signs of MS. Mitral leaflet thickening, reduced diastolic opening, and abnormal valve motion toward the left ventricular outflow tract were all common features. MS was also characterized by an abnormal diastolic transmitral signal from blood. Both left atrial and left ventricular dimensions were similar to those obtained at two-dimensional echocardiography (2-DE) (r = 0.89 and r = 0.86, respectively; p less than 0.001). A significant relationship was also found between the maximum mitral leaflet separation measured by cine MRI in diastole and the mitral valve area as calculated using the pressure half-time method and continuous wave Doppler (r = 0.81; p less than 0.001). These data indicate the improved ability of MRI to detect and assess MS and also suggest that this technique may contribute to the noninvasive assessment of MS.
