Alcohol use disorders and liver fibrosis: an update.

Alcoholic liver disease (ALD) is currently, worldwide, the second most common cause of human fatalities every year. Alcohol use disorders (AUDs) lead to 80% of hepatotoxic deaths, and about 40% of cases of cirrhosis are alcohol-related. An acceptable daily intake (ADI) of ethanol is hard to establish and studies somewhat controversially recommend a variety of dosages of ADI, whilst others regard any intake as dangerous. Steatohepatitis should be viewed as "the rate limiting step": generally, it can be overcome by abstinence, although in some patients, abstinence has little effect, with the risk of fibrosis, leading in some cases to hepatocellular carcinoma (HCC). Chronic alcoholism can also cause hypercortisolism, specifically pseudo-Cushing Syndrome, whose diagnosis is challenging. If fibrosis is spotted early, patients may be enrolled in detoxification programs to achieve abstinence. Treatment drugs include silybin, metadoxine and adenosyl methionine. Nutrition and the proper use of micronutrients are important, albeit often overlooked in ALD treatment. Other drugs, with promising antifibrotic effects, are now being studied. This review deals with the clinical and pathogenetic aspects of alcohol-related liver fibrosis and suggests possible future strategies to prevent cirrhosis.

Sex- and Gender-Based Analysis on Norepinephrine Use in Septic Shock: Why Is It Still a Male World?

Sex and gender are fundamental health determinants and their role as modifiers of treatment response is increasingly recognized. Norepinephrine is a cornerstone of septic shock management and its use is based on the highest level of evidence compared to dopamine. The related 2021 Surviving Sepsis Campaign (SCC) recommendation is presumably applicable to both females and males; however, a sex- and gender-based analysis is lacking, thus not allowing generalizable conclusions. This paper was aimed at exploring whether sex- and gender-disaggregated data are available in the evidence supporting this recommendation. For all the studies underpinning it, four pairs of authors, including a woman and a man, extracted data concerning sex and gender, according to the Sex and Gender Equity in Research guidelines. Nine manuscripts were included with an overall population of 2126 patients, of which 43.2% were females. No sex analysis was performed and gender was never reported. In conclusion, the present manuscript highlighted that the clinical studies underlying the SCC recommendation of NE administration in septic shock have neglected the likely role of sex and gender as modifiers of treatment response, thus missing the opportunity of sex- and gender-specific guidelines.

Botulinum toxin injection for chronic anal fissure: a prospective controlled study with long follow-up.

BACKGROUND: Botulinum toxin is an effective therapeutic option for chronic anal fissure. However, there is no evidence about treatment standardization and long-term follow-up. We aimed to evaluate the short- and long-term efficacy and safety of botulinum toxin compared to close lateral internal sphincterotomy, with a 5-year follow-up. METHODS: This was a prospective, controlled, single-center study conducted at University Hospital of Ferrara, Ferrara, Italy. The primary outcome was fissure healing at 1 month. Secondary outcomes were Quality-of-Life (QoL) at 1 month and after 5 years, and fissure recurrence at 6 months and 5 years. RESULTS: A total of 59 patients received botulinum toxin injection (Botox), and 32 underwent lateral internal sphincterotomy. At 1 month after treatments, postoperative pain decreased faster and significantly more in the Botox group (30 vs. 60 mm; P<0.001); fissure re-epithelization was observed in 59.4% of the surgical group compared to 25.4% of Botox (P=0.0001). Anal sphincter pressures decreased more in surgical group (P=0.044), although severe anal incontinence was present only in this subset (6.2%; P=0.041). Compared to surgery, patients who received Botox had higher satisfaction rates (P<0.001). Fissure recurrence at 6 months was more common in Botox than surgical group (16.9% vs. 3.2%, respectively; P=0.053). The overall healing rate improved in all patients and persisted at 12 months and 5 years in both groups with overall high patient satisfaction despite mild anal incontinence in 21.8% in the surgery group (P<0.05). CONCLUSIONS: Botox, rather than surgery, should be considered the first-line treatment for chronic anal fissure.

The role of echocardiography in pulmonary embolism for the prediction of in-hospital mortality: a retrospective study.

PURPOSE: Pulmonary Embolism (PE) is the third leading cause of cardiovascular death, following myocardial infarction and stroke. The latest European Society of Cardiology (ESC) guidelines on PE recommend short-term prognostic stratification based on right ventricular (RV) overload detected by transthoracic echocardiography (TTE) or contrast-enhanced chest CT. The aim of the study is to find out which of the signs of right ventricular dysfunction best predicts in-hospital mortality (IHM). METHODS: This is a monocentric, retrospective study including adult patients admitted from the emergency department with a c-e cCT confirmed diagnosis of PE between January 2018 and December 2022 who underwent a TTE within 48 h. RESULTS: 509 patients (median age 76 years [IQR 67-84]) were included, with 7.1% IHM. At univariate analysis, RV/LV ratio > 1 (OR 2.23, 95% CI 1.1-4.5), TAPSE < 17 mm (OR 4.73, 95% CI 2.3-9.8), the D-shape (OR 3.73, 95% CI 1.71-8.14), and LVEF < 35% (OR 5.78, 95% CI 1.72-19.47) resulted significantly correlated with IHM. However, at multivariate analysis including also haemodynamic instability, PESI class > II, and abnormal hs-cTnI levels, only LVEF < 35% (OR 5.46, 95% CI 1.32-22.61) resulted an independent predictor of IHM. CONCLUSION: Despite the recognised role of TTE in the early management of patients with circulatory shock and suspected PE, signs of RV dysfunction have been shown to be poor predictors of IHM, whereas severely reduced LVEF is an independent risk factor for in-hospital death.

Research gap in esophageal achalasia: a narrative review.

In recent years, new translational evidence, diagnostic techniques, and innovative therapies have shed new light on esophageal achalasia and revamped the attention on this relatively rare motility disorder. This narrative review aims to highlight the most recent progress and the areas where further research is needed. The four senior authors identified five topics commonly discussed in achalasia management: i.e. pathogenesis, role of functional lumen imaging probe in the diagnostic flow chart of achalasia, how to define the outcome of achalasia treatments, how to manage persistent chest pain after the treatment, and if achalasia patients' may benefit from a regular follow-up. We searched the bibliographic databases to identify systematic reviews, meta-analyses, randomized control trials, and original research articles in English up to December 2023. We provide a summary with the most recent findings in each of the five topics and the critical points where to address future research, such as the immune-genetic patterns of achalasia that might explain the transition among the different phenotypes, the need for a validated clinical definition of treatment success, the use of neuromodulators to manage chest pain, and the need for identifying achalasia patients at risk for cancer and who may benefit of long-term follow-up. Although undoubtedly, progress has been made on the definition and management of achalasia, unmet needs remain. Debated aspects range from mechanistic insights, symptoms, objective measure relationships, and accurate clinical responses to therapeutic interventions. Translational research is eagerly awaited to answer these unresolved questions.

Recurrence of Clostridioides difficile infection and mortality in older inpatients.

PURPOSE: The prevalence of Clostridioides difficile infection in older and frail population is extremely high and adverse outcomes, including future recurrences and premature mortality, are common. Nonetheless, the clinical risk profile for Clostridioides difficile recurrence in older people is still controversial. We aimed to investigate: 1) the association between Clostridioides difficile recurrence and 6-month mortality; 2) the risk factors for Clostridioides difficile recurrence after hospital discharge. METHODS: This is a retrospective study on adults with a first episode of Clostridioides difficile infection admitted to all Internal Medicine and Geriatrics Units of the University Hospital of Ferrara (Italy) between January 2018 and December 2020. For each patient, sociodemographic, clinical and laboratory data were collected through hospital database system. The primary and secondary outcomes were mortality and recurrence within 6 months from the first infectious episode, respectively. RESULTS: The mean age of the 386 enrolled patients was 77.8 years; 61.7% were females. Twelve percent patients had Clostridioides difficile recurrence and 32.1% patients died during the 6-month follow-up. At Cox analysis, after adjustment for the potential confounders, participants with recurrence reported a twofold risk of death compared to those without recurrence (HR, 95% CI 2.45, 1.59-3.78). Compared to patients treated with metronidazole, those treated with vancomycin showed a lower risk of recurrence (log-rank p < 0.001). CONCLUSION: Clostridioides difficile recurrence is associated with a higher risk of mortality and it may itself be a marker of frailty and vulnerability. Vancomycin treatment during the infectious episode was associated with lower recurrence rate, as compared to metronidazole.

Chronic intestinal pseudo-obstruction: associations with gut microbiota and genes expression of intestinal serotonergic pathway.

BACKGROUND: Pediatric chronic intestinal pseudo-obstruction (PIPO) is a rare disease characterized by symptoms and radiological signs suggestive of intestinal obstruction, in the absence of lumen-occluding lesions. It results from an extremely severe impairment of propulsive motility. The intestinal endocrine system (IES) jointly with the enteric nervous system (ENS) regulates secreto-motor functions via different hormones and bioactive messengers/neurotransmitters. The neurotransmitter 5-hydroxytryptamine (5-HT) (or serotonin) is linked to intestinal peristalsis and secretory reflexes. Gut microbiota and its interplay with ENS affect 5-HT synthesis, release, and the subsequent serotonin receptor activation. To date, the interplay between 5-HT and gut microbiota in PIPO remains largely unclear. This study aimed to assess correlations between mucosa associated microbiota (MAM), intestinal serotonin-related genes expression in PIPO. To this purpose, biopsies of the colon, ileum and duodenum have been collected from 7 PIPO patients, and 7 age-/sex-matched healthy controls. After DNA extraction, the MAM was assessed by next generation sequencing (NGS) of the V3-V4 region of the bacterial RNA 16 S, on an Illumina Miseq platform. The expression of genes implicated in serotoninergic pathway (TPH1, SLC6A4, 5-HTR3 and 5-HTR4) was established by qPCR, and correlations with MAM and clinical parameters of PIPO have been evaluated. RESULTS: Our results revealed that PIPO patients exhibit a MAM with a different composition and with dysbiosis, i.e. with a lower biodiversity and fewer less connected species with a greater number of non-synergistic relationships, compared to controls. qPCR results revealed modifications in the expression of serotonin-related intestinal genes in PIPO patients, when compared to controls. Correlation analysis do not reveal any kind of connection. CONCLUSIONS: For the first time, we report in PIPO patients a specific MAM associated to underlying pathology and an altered intestinal serotonin pathway. A possible dysfunction of the serotonin pathway, possibly related to or triggered by an altered microbiota, may contribute to dysmotility in PIPO patients. The results of our pilot study provide the basis for new biomarkers and innovative therapies targeting the microbiota or serotonin pathways in PIPO patients.

Gluten and Wheat in Women's Health: Beyond the Gut.

Since the rise of awareness of gluten/wheat-related disorders in the academic and clinical field in the last few decades, misinformation regarding the gluten-free diet (GFD) and its impact on health has been spreading among the general population. Despite the established link between gluten and celiac disease (CD), where a GFD is mandatory to reach clinical and histological remission, things are more complicated when it comes to non-celiac gluten/wheat sensitivity (NCGWS) and other autoimmune/dysimmune disorders. In the last conditions, a beneficial effect of gluten withdrawal has not been properly assessed, but still is often suggested without strong supporting evidence. In this context, women have always been exposed, more than men, to higher social pressure related to nutritional behaviors and greater engagement in controlling body weight. With this narrative review, we aim to summarize current evidence on the adherence to a GFD, with particular attention to the impact on women's health.

Chronic constipation in Parkinson's disease: clinical features and molecular insights on the intestinal epithelial barrier.

Background: Chronic constipation (CC) is a severe symptom in Parkinson's disease (PD), with an unclear pathogenesis. Abnormalities of the enteric nervous system (ENS) and/or intestinal epithelial barrier (IEB) may be pathophysiologically relevant in PD patients with CC. We investigated possible molecular changes of the IEB in PD/CCs compared with CCs and controls. Methods: Twelve PD/CCs (2 female, age range 51-80 years), 20 CCs (15 female, age range 27-78 years), and 23 controls (11 female, age range 32-74 years) were enrolled. Ten PD/CCs and 10 CCs were functionally characterized by anorectal manometry (AM) and transit time (TT). Colon biopsies were obtained and assessed for gene and protein expression, and localization of IEB tight junction markers claudin-4 (CLDN4), occludin-1 (OCCL-1), and zonula occludens-1 (ZO-1) by RT-qPCR, immunoblot and immunofluorescence labeling. Results: PD/CCs were clustered in 2 functional categories: patients with delayed TT and altered AM (60%), and a second group showing only modifications in AM pattern (40%). Gene expression of CLDN4, OCCL-1 and ZO-1 was higher in PD/CCs than controls (P<0.05). Conversely, PD/CCs showed a trend to decrease (P>0.05) in CLDN4 and OCCL-1 protein levels than controls, whereas ZO-1 protein was comparable. In PD/CCs compared with controls, decreasing tendency of vasoactive intestinal polypeptide mRNA, protein and immunoreactive fiber density were observed, although the difference was not statistically significant. Conclusion: Transit and anorectal dysfunctions in PD/CCs are associated with difference in ZO-1, OCCL-1 and CLDN4 expression, thus supporting the role of an altered IEB as a contributory mechanism to possible neuronal abnormalities.

Vasoactive Intestinal Polypeptide Plays a Key Role in the Microbial-Neuroimmune Control of Intestinal Motility.

BACKGROUND & AIMS: Although chronic diarrhea and constipation are common, the treatment is symptomatic because their pathophysiology is poorly understood. Accumulating evidence suggests that the microbiota modulates gut function, but the underlying mechanisms are unknown. We therefore investigated the pathways by which microbiota modulates gastrointestinal motility in different sections of the alimentary tract. METHODS: Gastric emptying, intestinal transit, muscle contractility, acetylcholine release, gene expression, and vasoactive intestinal polypeptide (VIP) immunoreactivity were assessed in wild-type and Myd88-/-Trif-/- mice in germ-free, gnotobiotic, and specific pathogen-free conditions. Effects of transient colonization and antimicrobials as well as immune cell blockade were investigated. VIP levels were assessed in human full-thickness biopsies by Western blot. RESULTS: Germ-free mice had similar gastric emptying but slower intestinal transit compared with specific pathogen-free mice or mice monocolonized with Lactobacillus rhamnosus or Escherichia coli, the latter having stronger effects. Although muscle contractility was unaffected, its neural control was modulated by microbiota by up-regulating jejunal VIP, which co-localized with and controlled cholinergic nerve function. This process was responsive to changes in the microbial composition and load and mediated through toll-like receptor signaling, with enteric glia cells playing a key role. Jejunal VIP was lower in patients with chronic intestinal pseudo-obstruction compared with control subjects. CONCLUSIONS: Microbial control of gastrointestinal motility is both region- and bacteria-specific; it reacts to environmental changes and is mediated by innate immunity-neural system interactions. By regulating cholinergic nerves, small intestinal VIP plays a key role in this process, thus providing a new therapeutic target for patients with motility disorders.

Diagnostic accuracy of Point Of Care UltraSound (POCUS) in clinical practice: A retrospective, emergency department based study.

AIMS: Point-of-care ultrasound (POCUS) is the acquisition and interpretation of ultrasound imaging at the bedside to solve specific clinical questions based on signs and symptoms of presentation. While several studies evaluated POCUS diagnostic accuracy for a variety of clinical pictures in the emergency department (ED), only a few data are available on POCUS diagnostic accuracy performed by physicians with different POCUS skills. The objective of this research was to evaluate the diagnostic accuracy of POCUS compared to standard diagnostic imaging in the ED. MATERIALS AND METHODS: This was a retrospective study conducted in the ED of a third-level university hospital. Patients who underwent cardiac, thoracic, abdominal, or venous lower limb POCUS and a standard imaging examination between June 2021 and January 2022 were included. RESULTS: 1047 patients were screened, and 844 patients included. A total of 933 POCUS was included (102, 12.09%, cardiac; 466, 55.21%, thoracic; 336, 39.8%, abdominal; 29, 3.44%, lower limb venous POCUS), accounting for 2029 examinations. POCUS demonstrated 96.6% (95% CI 95.72-97.34) accuracy, 47.73 (95% CI 33.64-67.72) +LR, 0.09 (95% CI 0.06-0.12) -LR. +LR was greater than 10 for all investigations but for hydronephrosis (5.8), and -LR never exceeded 0.4. CONCLUSIONS: POCUS exhibited high diagnostic accuracy for virtually all conditions when performed by emergency department physicians.

Predicting in-hospital mortality in patients admitted from the emergency department for pulmonary embolism: Incidence and prognostic value of deep vein thrombosis. A retrospective study.

BACKGROUND: Pulmonary embolism (PE) is one of the most common causes of death from cardiovascular disease. Although deep vein thrombosis (DVT) is the leading cause of PE, its prognostic role is unclear. This study investigated the incidence and prognostic value of DVT in predicting in-hospital mortality (IHM) in patients admitted from the emergency department (ED) for PE. METHODS: This retrospective cohort study was conducted in the ED of a third-level university hospital. Patients over 18 years admitted for PE between 1 January 2018 and 31 December 2022 were included. RESULTS: Five hundred and thirty patients (mean age 73.13 years, 6% IHM) were included. 69.1% of cases had DVT (36.4% unilateral femoral vein, 3.6% bilateral, 39.1% unilateral popliteal vein, 2.8% bilateral, 45.7% distal vein thrombosis and 7.4% iliocaval involvement). Patients who died in hospital had a higher Pulmonary Embolism Severity Index (PESI) (138.6 vs. 99.65, p < 0.001), European Society of Cardiology risk class (15.6% vs. 1%, intermediate-high in 50% vs. 6.4%, p < 0.001) and more DVT involving the iliac-caval vein axis (18.8% vs. 6.6%, p = 0.011). PESI class >II, right ventricular dysfunction, increased blood markers of myocardial damage and involvement of the iliocaval venous axis were independent predictors of IHM on multivariate analysis. CONCLUSIONS: Although further studies are needed to confirm the prognostic role of DVT at PE, involvement of the iliocaval venous axis should considered to be a sign of a higher risk of IHM and may be a key factor in prognostic stratification.

Distribution, quantification, and characterization of substance P enteric neurons in the submucosal and myenteric plexuses of the porcine colon.

The pig is an important translational model for studying intestinal physiology and disorders for its many homologies with humans, including the organization of the enteric nervous system (ENS), the major regulator of gastrointestinal functions. This study focused on the quantification and neurochemical characterization of substance P (SP) neurons in the pig ascending (AC) and descending colon (DC) in wholemount preparations of the inner submucosal plexus (ISP), outer submucosal plexus (OSP), and myenteric plexus (MP). We used antibodies for the pan-neuronal marker HuCD, and choline acetyltransferase (ChAT) and neuronal nitric oxide synthase (nNOS), markers for excitatory and inhibitory transmitters, for multiple labeling immunofluorescence and high-resolution confocal microscopy. The highest density of SP immunoreactive (IR) neurons was in the ISP (222/mm2 in the AC, 166/mm2 in the DC), where they make up about a third of HuCD-IR neurons, compared to the OSP and MP (19-22% and 13-17%, respectively, P < 0.001-0.0001). HuCD/SP/ChAT-IR neurons (up to 23%) were overall more abundant than HuCD/SP/nNOS-IR neurons (< 10%). Most SP-IR neurons contained ChAT-IR (62-85%), whereas 18-38% contained nNOS-IR with the highest peak in the OSP. A subpopulation of SP-IR neurons contains both ChAT- and nNOS-IR with the highest peak in the OSP and ISP of DC (33-36%) and the lowest in the ISP of AC (< 10%, P < 0.001). SP-IR varicose fibers were abundant in the ganglia. This study shows that SP-IR neurons are functionally distinct with variable proportions in different plexuses in the AC and DC reflecting diverse functions of specific colonic regions.

From the organ bath to the whole person: a review of human colonic motility.

Motor function of the colon is essential for health. Our current understanding of the mechanisms that underlie colonic motility are based upon a range of experimental techniques, including molecular biology, single cell studies, recordings from muscle strips, analysis of part or whole organ ex vivo through to in vivo human recordings. For the surgeon involved in the clinical management of colonic conditions this amounts to a formidable volume of material. Here, we synthesize the key findings from these various experimental approaches so that surgeons can be better armed to deal with the complexities of the colon.

Evaluating the molecular and genetic mechanisms underlying gut motility disorders.

INTRODUCTION: Gastrointestinal (GI) motility disorders comprise a wide range of different diseases affecting the structural or functional integrity of the GI neuromusculature. Their clinical presentation and burden of disease depends on the predominant location and extent of gut involvement as well as the component of the gut neuromusculature affected. AREAS COVERED: A comprehensive literature review was conducted using the PubMed and Medline databases to identify articles related to GI motility and functional disorders, published between 2016 and 2023. In this article, we highlight the current knowledge of molecular and genetic mechanisms underlying GI dysmotility, including disorders of gut-brain interaction, which involve both GI motor and sensory disturbance. EXPERT OPINION: Although the pathophysiology and molecular mechanisms underlying many such disorders remain unclear, recent advances in the assessment of intestinal tissue samples, genetic testing with the application of 'omics' technologies and the use of animal models will provide better insights into disease pathogenesis as well as opportunities to improve therapy.

Liquorice Toxicity: A Comprehensive Narrative Review.

BACKGROUND: Renowned since ancient times for its medical properties, liquorice is nowadays mainly used for flavoring candies or soft drinks. Continuous intake of large amounts of liquorice is a widely known cause of pseudo-hyperaldosteronism leading to hypertension and hypokalemia. These manifestations are usually mild, although in some cases may generate life-threatening complications, i.e., arrhythmias, muscle paralysis, rhabdomyolysis, and coma. In addition, liquorice has an important estrogenic-like activity. METHODS: We summarized the current knowledge about liquorice and reviewed 104 case reports in both the English and Italian languages from inception to June 2023 concerning complications due to an excess of liquorice intake. RESULTS: In contrast to most published data, female sex and old age do not appear to be risk factors. However, hypertension and electrolyte imbalance (mainly hypokalemia) are prevalent features. The detection of glycyrrhetinic acid in blood is very uncommon, and the diagnosis is essentially based on an accurate history taking. CONCLUSIONS: Although there is not a significant mortality rate, liquorice toxicity often requires hospitalization and therefore represents a significant health concern. Major pharmaceutical drug regulatory authorities should solicit public awareness about the potentially dangerous effects caused by excessive use of liquorice.

The role of serology in the diagnosis of coeliac disease.

Serology has significantly revolutionized the knowledge of celiac disease (CD), leading to the identification of unsuspected patients in at-risk CD groups, thereby increasing the number of CD diagnoses compared to the pre-screening era. Several markers for CD with a progressive diagnostic accuracy have been identified over the years, but only three of them, i.e. anti-tissue transglutaminase (anti-tTG), anti-endomysial (EmA) and anti-deamidated gliadin antibodies (DGP) are currently assessed in the daily clinical practice. A thorough review of the literature identified 44 original studies published between 1998 to 2022 for a total of 5098 pediatric and adult CD patients (without selective IgA deficiency) and 11930 disease controls. The results highlighted that anti-tTG IgA exhibited a higher sensitivity for CD (93.4%) than EmA IgA (92.8%), DGP IgG (81.8%) and DGP IgA (83.8%). The specificity of EmA IgA (99%) resulted to be higher than those of anti-tTG IgA (95.8%), DGP IgG (96.4%) and DGP IgA (92.1%). In patients with selective IgA deficiency, a condition closely related to CD, serological screening should include one of the three antibodies of IgG class, since anti-tTG, DGP and EmA have a very similar diagnostic accuracy in this clinical setting. According to age, there are two main diagnostic strategies for CD detection. In children, the revised ESPGHAN 2020 guidelines established that CD could be diagnosed in both symptomatic and asymptomatic children by high anti-tTG IgA titers (>10 times the cut-off) and EmA positivity with no need to obtain duodenal biopsy and HLA typing. In adult patients, although high tTG IgA titers (confirmed by EmA IgA positivity) correlate with villous atrophy, an intestinal biopsy is still considered mandatory for confirming CD diagnosis. Currently, a case finding approach in at-risk groups is preferred to mass screening for CD detection.

Multi-disciplinary Insights from the First European Forum on Visceral Myopathy 2022 Meeting.

Visceral myopathy is a rare, life-threatening disease linked to identified genetic mutations in 60% of cases. Mostly due to the dearth of knowledge regarding its pathogenesis, effective treatments are lacking. The disease is most commonly diagnosed in children with recurrent or persistent disabling episodes of functional intestinal obstruction, which can be life threatening, often requiring long-term parenteral or specialized enteral nutritional support. Although these interventions are undisputedly life-saving as they allow affected individuals to avoid malnutrition and related complications, they also seriously compromise their quality of life and can carry the risk of sepsis and thrombosis. Animal models for visceral myopathy, which could be crucial for advancing the scientific knowledge of this condition, are scarce. Clearly, a collaborative network is needed to develop research plans to clarify genotype-phenotype correlations and unravel molecular mechanisms to provide targeted therapeutic strategies. This paper represents a summary report of the first 'European Forum on Visceral Myopathy'. This forum was attended by an international interdisciplinary working group that met to better understand visceral myopathy and foster interaction among scientists actively involved in the field and clinicians who specialize in care of people with visceral myopathy.

Comparison between Capillary and Serum Lactate Levels in Predicting Short-Term Mortality of Septic Patients at the Emergency Department.

Sepsis is a time-dependent and life-threating condition related to macro- and micro-circulatory impairment leading to anaerobic metabolism and lactate increase. We assessed the prognostic accuracy of capillary lactates (CLs) vs. serum ones (SLs) on 48-h and 7-day mortality in patients with suspected sepsis. This observational, prospective, single-centre study was conducted between October 2021 and May 2022. Inclusion criteria were: (i) suspect of infection; (ii) qSOFA ≥ 2; (iii) age ≥ 18 years; (iv) signed informed consent. CLs were assessed with LactateProTM2®. 203 patients were included: 19 (9.3%) died within 48 h from admission to the Emergency Department, while 28 (13.8%) within 7 days. Patients deceased within 48 h (vs. survived) had higher CLs (19.3 vs. 5 mmol/L, p < 0.001) and SLs (6.5 vs. 1.1 mmol/L, p = 0.001). The best CLs predictive cut-off for 48-h mortality was 16.8 mmol/L (72.22% sensitivity, 94.02% specificity). Patients within 7 days had higher CLs (11.5 vs. 5 mmol/L, p = 0.020) than SLs (2.75 vs. 1.1 mmol/L, p < 0.001). The multivariate analysis confirmed CLs and SLs as independent predictors of 48-h and 7-day mortality. CLs can be a reliable tool for their inexpensiveness, rapidity and reliability in identifying septic patients at high risk of short-term mortality.
