Roux-en-Y Gastric Bypass after Laparoscopic Sleeve Gastrectomy Failure: Could the Number of Previous Operations Influence the Outcome?

After a failed laparoscopic adjustable gastric band (LAGB), laparoscopic sleeve gastrectomy (LSG) has been proposed as revisional surgery. Those patients that receive a second restrictive procedure fall into a small subgroup of patients with more than one restrictive procedure (MRP). If also the second restrictive procedure fails, the correct surgical strategy is a challenge for the surgeon. Roux-en-Y gastric bypass (RYGB) may be an option but there is no evidence in the literature on whether the procedure is effective in treating failures after MRP. This study aims to evaluate the influence of the previous number of restrictive interventions (MRP vs single LSG) in the results of RYGB as revisional surgery. We have retrospectively analyzed patients who underwent conversion from laparoscopic sleeve gastrectomy (LSG), or from multiple restrictive procedures (MRP), to RYGB for weight regain (WR) or insufficient weight loss (IWL) between 2009 and 2019. The number of patients analyzed was 69 with conversion to RYGB after LSG and 44 after MRP. The reduction of excess weight (%TWL) at 3, 6, 12, 24 RYGB postoperative months was respectively of 11.03%, 16.39%, 21.43%, and 24.22% in the MRP group, and of 10.97%, 16.4%, 21.22%, and 22.71% in the LSG group. No significant difference was found in %TWL terms after RYGB for the MRP group and the LSG group with an overall %TWL, which was 11.00 ± 6.03, 16.40 ± 8.08, 21.30 ± 9.43, and 23.30 ± 9.91 respectively at 3, 6, 12, and 24 months. The linear regression model highlighted a positive relationship between the %EWL post-bypass at 24 months and the time elapsed only between the LSG and RYGB in the MRP group patients (p < 0.001). RYGB has proved to be a reliable technique with good results in terms of weight loss after failed bariatric surgery both in patients who previously underwent MRP and in those who underwent exclusively LSG. RYGB showed better results in patients who experienced WR than in those who had IWL from previous techniques.

Insights and expectations of healthcare professionals on the implementation of the updated pediatric regional immunization Calendar in Calabria, Italy.

The Regional Immunization Calendar in Calabria, a region of Italy, was updated in 2022, introducing optional co-administration of three injectable vaccines, with one oral vaccine, at 3 and 5 months old, and three injectable vaccines at 13-14 months old. In this project, the opinions and expectations of healthcare professionals (HCPs) in Calabria were investigated, with respect to the updated recommended practices. An 11-question survey was developed, which addressed concepts and topics related to immunization calendar implementation. Focus group discussions were also organized to provide further insight on the survey findings. A total of 132 HCPs completed the survey (86 public health providers [PHs] and 46 family pediatricians [FPs]). Overall, ≥50% of respondents agreed that vaccine co-administration would be advantageous for public health by reducing the number of vaccination sessions required. Most PHs and FPs agreed that dissemination of available safety data on vaccine co-administration is a necessary action to facilitate effective implementation of the strategy into clinical practice. The importance of safety data related to vaccine co-administration was supported further by discussions held in PH and FP focus groups. Overall, these findings demonstrate support from HCPs in Calabria for vaccine co-administration, and highlight key activities needed for successful uptake.

Policy of vaccination of "fragile children": Results of a survey of 14 Italian children's hospitals.

Children with chronic disease are at higher risk of invasive infectious disease, including several vaccine-preventable infections. The Italian Association of Pediatric Hospitals (AOPI) carried out a survey of immunization practices: 14/16 AOPI hospitals completed the survey; 50% of them include 100-199 beds, while 21% have <100 beds. In 12/14 hospitals (86%) all vaccinations included in the National Immunization Plan (plus influenza e COVID-19 vaccines) are available for inpatients, in selected wards (n = 4), on single pediatrician initiative (n = 3), by a centralized in-hospital immunization service (n = 2), and the remaining 3 in a "protected vaccination area" or in a COVID-19 pathway. The wards in which vaccination is more frequently offered to in-patients are: General Pediatrics, Neonatology, Pediatric Hematology & Oncology, Pediatric Diabetology, Pediatric Cardiology, and Pediatric Infectious Diseases (range, 58% to 83%). In 58% of vaccinating hospitals, <500 vaccinations/year are reported, while in 17% this number is >2,000/year. A COVID-19 vaccination team is in place for any inpatient child older than 12 years in 42% of hospitals, in 42% only for "fragile" children. A centralized in-hospital immunization service is an emerging model that may contribute to increase compliance to vaccination of fragile patients and to fight against vaccination hesitancy.

Sarcopenia and visceral fat in patients with incisional hernia after urgent laparotomy.

PURPOSE: Various risk factors have been associated with the development of incisional hernia (IH). Some recent papers underlined that visceral fat could be a reliable indicator. Another risk factor which is of increasing clinical interest is sarcopenia. Recent studies have identified it as an independent predictor of poor postoperative outcomes following abdominal surgery. We aimed to investigate the role of visceral fat and skeletal muscle as emerging risk factors for IH after urgent laparotomy. METHODS: Patients aged 18 years or older who underwent urgent median laparotomy and with continuous direct suturing of the laparotomy were included. They were categorized into two groups: those with a median IH and those without IH at 12-month follow-up. Demographic data were prospectively collected while CT scans were retrospectively reviewed. The data were compared among two groups. RESULTS: From January 2018 to May 2021, 364 patients underwent urgent surgery in our Department, of whom 222 were aged >18 years old and underwent median laparotomy. Forty-four patients had diagnosis of median IH, while 41 patients without IH were identified as the control group. Statistically significant differences emerged for BMI and for the area of visceral fat. The association with the presence/absence of sarcopenia was not significant. CONCLUSION: Even when surgery is performed in urgent settings, it could be important to identify patients at risk, especially as CT scans are generally available for all patients with urgent abdominal disease.

Effects of Rapid Maxillary Expander and Delaire Mask Treatment on Airway Sagittal Dimensions in Pediatric Patients Affected by Class III Malocclusion and Obstructive Sleep Apnea Syndrome.

Obstructive sleep apnea syndrome (OSAS) is a sleep-related breathing disorder that is very common in pediatric patients. In the literature, there are very few studies concerning the association between OSAS and class III malocclusion in children. The use of a rapid maxillary expander (RME) in association with the Delaire mask is a common treatment protocol for class III malocclusion. The aim of this work was to evaluate the cephalometric variations of upper airway dimensions and OSA-related clinical conditions after orthodontic treatment with an RME and the Delaire mask, as recorded in pediatric patients with a class III malocclusion who were affected by OSAS. In this preliminary study, 14 pediatric patients with mixed dentition, aged between 6 and 10 years, were selected. All patients were treated with an RME and the Delaire mask. Pre- and post-treatment cephalometric radiographs were traced, analyzed, and compared. The results demonstrated a significant increase in the upper airway linear measurements and the nasopharyngeal and oropharyngeal dimensions (p ≤ 0.05). This increase creates an improvement in airway patency and in OSAS-related clinical conditions. The use of the RME in association with the Delaire mask can be effective in the treatment of pediatric patients with a class III malocclusion who are affected by OSAS.

Effects of single rinse with three different types of mouthwashes on VSCs levels in morning breath: Randomized, double-blind, crossover clinical trial.

OBJECTIVE: Morning breath is a temporary and unpleasant malodour sourced from the mouth, which occurs upon awakening. This double-blind, crossover, randomized clinical trial aimed to evaluate the bad-breath suppression of three commercially available mouthwashes: Mentadent Professional® Chlorhexidine 0.05% with vitamin C (ChxC), Meridol Alito Sicuro® (SnF2 ) and CB12® (ZnChx) compared to a placebo (PbO) on morning halitosis. METHODS: Thirty-two subjects refraining from oral hygiene practices for 12 h before the evaluation, performed a 30-s rinse with 15 ml of mouthwash, followed by a 5-s gargle, in the evening before bedtime. In order to assess morning halitosis, visual inspection (Winkel Tongue Coating Index), organoleptic (Rosenberg index) and chromatographic measurements were used. Gas chromatography was carried out by means of a dedicated device, the Oral Chroma. The recorded measurements have to be considered solely after the rinse since no data about the pre-exposure were available. A washout period of 1 week passed between one administration and the next. RESULTS: The mean value of the organoleptic indices after administration of ChxC mouthwash is similar to ZnChx, SnF2 and PbO values. Thus, no statistically significant differences were recorded among the mouthwashes and PbO. Nevertheless, ChxC seems to be more efficient in comparison with the PbO regarding VSCs levels analysed with Oral Chroma, (CH3 SH; p = 0.0081) and [(CH3 )2 S; p = 0.0003]. CONCLUSION: Considering our limited sample, instrumental examination demonstrated that the use of the analysed mouthwashes can result in low VSCs levels after 12 h from a single rinse. Furthermore, the highest number of patients (n = 14) were proved to be free from bad smell after using a single administration of ChxC with respect to the other commercial products. The other tested mouthwashes did not show better performances with respect to the placebo after a single rinse.

Active surveillance of adverse events after immunization (AEFI) from the Local Health Unitof Ferrara, Italy.

Introduction: Vaccine vigilance implies the collection, evaluation, analysis and communication of adverse events following immunization (AEFI) and is a useful tool for vaccine monitoring allowing, even after approval and marketing, to check its safety/tolerability. The multiregional project "Active surveillance of adverse vaccine reactions", joined by the AUSL of Ferrara, is aimed at making parents of children, who have undergone at least one vaccination provided by the regional vaccination calendar in the first 24 months of life, aware of the reporting of any AEFI via mobile phone-SMS. Methods: An analysis of the project data, collected in the period March 2018 - May 2019, was carried out, to evaluate the effectiveness of the reporting tool and the type and frequency of AEFI. Anonymized data were analyzed by number, gender, distribution by age, type of vaccine, adverse event, severity and outcome. Results: A total of 1,494 consents and 983 SMS messages were obtained from parents. The vaccine doses carried out were 1,984 (28.3% hexavalent, 28% PCV13, 17% anti-rotavirus, 14.3% Men-B). Almost all (99.5%) AEFI were classified as "not serious". Based on the Organ System Class (SOC), most reports are related to "General Disorders and Administration Site Conditions" (52.3%), followed by "Psychiatric Disorders" (26.5%) and "Metabolic and nutrition disorders" (12.5%). Conclusions: The reported AEFI are in line with the ones reported in the literature. Reporting via SMS is a valid vaccine surveillance tool contributing to the qualitative and quantitative improvement of the information transmitted.

Colostomy Reversal following Hartmann's Procedure: The Importance of Timing in Short- and Long-Term Complications: A Retrospective Multicentric Study.

The restoration of bowel continuity following Hartmann's Procedure (HP) has been reported hitherto with high morbidity and mortality rates. No clear guidelines exist about timing in Hartmann's Reversal (HR), the literature data being conflicting. We have sought to investigate the effect of the interval time between HP and HR in short- and long-term HR outcomes through a retrospective study based on consecutive patients undergoing HR between 2009 and 2017 in two regional hospitals in Italy. Demographic characteristics, comorbidities, intra- and post-operative data, as well as early complications, were recorded. Long-term data were collected on the surgical site occurrences of Incisional Ventral Hernia (IVH). One hundred and five patients were recruited for the study. Late HR, female gender, and long operating time were related to the highest incidence of peri-operative complications. Patients who developed IVH had undergone HR at significantly shorter times and had a higher Body Mass Index (BMI). The timing of HR seems to be an important variable linked to the onset of early and late post-operative complications. The patients submitted to early HR show a significantly lower complication rate but, at the same time, a higher rate of IVH incidence after restorative surgery. These data, in our opinion, reflect the need for planning, where possible, an early restoration of bowel continuity after HP.

Systemic inflammation response index (SIRI) as predictor of anastomotic leakage after total gastrectomy for gastric cancer.

BACKGROUND: Esophago-jejunostomy leakage (EJL) it the most dreaded septic complication after total gastrectomy for gastric cancer. Early detection and treatment of this complication may improve outcomes. Systemic Inflammation Response Index (SIRI) is a marker that reflects systemic inflammation. METHODS: The SIRI was developed in a training cohort of 180 patients who underwent elective open total gastrectomy with esophago-jejunal anastomosis for gastric cancer from January 2009 to December 2013. To verify the prognostic value of SIRI score we recruited 192 patients treated from January 2014 to December 2021 as the validation cohort. The optimal cut-off value of SIRI was determined by receiver operating characteristic curve. Univariate and multivariate analysis was performed. RESULTS: An optimal cut-off point for the SIRI of 0.82 divided the patients into a low SIRI group and high SIRI group in the training cohort. Patients with a SIRI ≥0.82 was found to be significantly associated with EJL. Univariable analysis showed that NLR, PLR, MLR, SII, and SIRI were prognostic factors for EJL in the training cohort. In multivariable analysis, EJL high level of SIRI was identified as independent prognostic factor. CONCLUSIONS: Preoperative SIRI may be helpful in identifying patients at greater risk for developing EJL after total gastrectomy.

Efficacy and Tolerability of a New Formulation in Rectal Ointment Based on Zn-L-Carnosine (Proctilor®) in the Treatment of Haemorrhoidal Disease.

Haemorrhoidal disease (HD) shows high prevalence in western countries, reaching 4.4% per year in the US. Topical preparations are the first-line treatments, which are readily available as "over-the-counter" (OTC) products, often containing a nonstandardised mixture of "natural" remedies, or anaesthetics or cortisol;those latter are not free from undesirable effects. The Zinc-L-Carnosine is a cytoprotective compound, promoting mucosal repair in the gastrointestinal tract and also in mucosal repair, following radiation injuries to the rectum as well as in ulcerative colitis. Our aim was to study the efficacy of Zinc-L-Carnosine in relieving acute symptoms of HD, testing a preparation in the rectal ointment, Proctilor®, in patients complaining of bleeding or thrombosed piles. In a multicentre open trial, 21 patients older than 18 years of age were enrolled. The symptoms of HD were graded according to the Haemorrhoidal Disease Symptoms Score (HDSS) in association with the Short Health Scale (SHS) to assess the influence of HD on quality of life. The pain was assessed with the VAS score, bowel habit by means of the Bristol scale. The patients were evaluated at enrolment (T0) and 2 (T1) and 4 (T2) weeks of treatment with Proctilor® rectal ointment. There were 10 men and 11 women; mean age, 49 years. Pain, bleeding, and thrombosis were all significantly reduced after treatment; the mean VAS score decreased from 4.71 ± 3.05 at T0 to.52 ± 0.87 and.05 ± 0.22 at T1 and T2, respectively; (mean ± SD; p < 0.001 in both cases). Similarly, the HDSS score showed to be significantly reduced between T0, T1 (8.05 ± 4.55 vs. 1.14 ± 1.01), and T2 (8.05 ± 4.55 vs. 24 ± 0.44) (mean ± SD; p < 0.001 in both cases). Quality of life showed to be improved as the SHS score decreased significantly with treatment (7.90 ± 4.17 at T0 vs. 4.24 ± 0.44 at T1 vs. 4.05 ± 0.22 at T2; mean ± SD; p < 0.001 in both cases). The Bristol score of defecation remained substantially unchanged. No side effects or discontinuation of treatment were reported. Results of our investigation suggest a role of Proctilor® rectal ointment in treating symptomatic HD with good results and an excellent safety profile. However, our preliminary results encourage further studies on a larger number of patients to confirm the role of Zinc-L-Carnosine in the rectal ointment for the topical treatment of HD.

Effectiveness and Safety of Intravenous Sedation with Propofol in Non-Operating Room Anesthesia (NORA) for Dental Treatment in Uncooperative Paediatric Patients.

BACKGROUND: Uncooperative children require sedative approach for dental treatment. The aim was to assess the effectiveness of Propofol in "Non-Operating Room Anesthesia" (NORA) for paediatric dental treatment; intraoperative side effects; postoperative side effects; post-discharge effects. METHODS: a prospective study, involving 109 uncooperative children undergoing sedation in NORA using Propofol for dental treatment, was performed. Working sessions, success/failure, intraoperative and postoperative side effects, number of treatment; type of procedure were assessed. Parents completed a post-discharge questionnaire on: pain; crying; fever; vomiting; headache; drowsiness; excitability; irritability; ability to eat; drugs and medical care needing. RESULTS: Success: 96.7%. Intraoperative side effects: 33.3%. Postoperative side effects: 6.4%. Statistically significant association between: intraoperative side effects and age (p = 0.001), health status (p = 0.0007), weight (p = 0.038), respectively; intraoperative side effects and number/ type of dental treatment (p = 0.0055) and scaling (p = 0.0001), respectively. For post-discharge questionnaires, statistically significant association between: age and crying (p = 0.0001) and headache (p = 0.002), respectively; health status and crying (p = 0.015) and drugs needing (p = 0.04), respectively; weight and crying (p = 0.0004); extraction and pain (p = 0.0001) and crying (p= 0.0073), respectively; scaling and crying (p = 0.04), excitability and irritability (p = 0.03), respectively. CONCLUSION: Propofol in NORA was effective with minimal side effects.

Drain Amylase Levels in the Early Diagnosis of Gastric Leak after Laparoscopic Sleeve Gastrectomy.

OBJECTIVES: Laparoscopic sleeve gastrectomy is gaining popularity as a bariatric option. Gastric leak is the most dreaded septic complication after this procedure. This study investigated levels of drain amylase that could be useful for predicting gastric leak before its clinical presentation. SUBJECTS AND METHODS: This prospective observational study was carried out in 167 patients who underwent sleeve gastrectomy for morbid obesity between February 2014 and March 2020. Measurement of drain amylase levels (DALs) was adapted as a routine procedure. The results of the receiver operative characteristic (ROC) curve analysis revealed an optimal drain amylase levels cutoff point of 814.18 IU/L. Consequently, the DALs were classified as DALs <814.18 or DALs ≥814.18 for all subsequent analyses. RESULTS: Gastric leak occurred in 6 patients. Drain amylase levels of 167 patients were tested. The mean value for patients without leak was 71.13 ± 72.11 IU/L; for patients with leak, it was 4,687 ± 6,670 IU/L (p < 0.001). Using ROC curve analysis, the mean ± standard error of the area under the curve for DALs on postoperative day 1 was 0.9927 ± 0.0075, CI = 0.978-1.00, and a cutoff level at 814.18 IU/L for predicting gastric leak achieved 83.33% sensitivity and 100% specificity with positive predictive value of 100% and negative predictive value 99.38%. All patients with a leak, but one, had a drain amylase level >814.18 IU/L. CONCLUSION: The determination of drain amylase levels after sleeve gastrectomy is a significant indicator of gastric leak with high sensitivity and specificity.

Examining the Post-operative Well-Being of Women Who Underwent Mammoplasty: A Cross-Sectional Study.

Background: Mammoplasty is the most common surgery used for breast augmentation (aesthetic plastic) and breast reconstruction (disease-related plastic) in women who have been diagnosed with and surgically treated for regional breast cancer with modified radical mastectomy. This study aims to examine the long-term effects of mammoplasty on the psychological well-being of women. Methods: Participants were 44 women aged 30-50 years (mean = 40.4 ± 5.9). They were divided into two groups based on the purpose of the breast surgery they underwent [augmentation surgery (AS) vs. reconstruction surgery (RS)] and the time that had elapsed since their surgery (≤3 vs. >3 years). Results: Our findings suggest that women who underwent AS reported a decline in their psychological well-being over time. The women who had undergone AS ≤3 and >3 years did not show any differences in emotional functioning, with the exception of the BREAST-Q scores on the satisfaction with breasts subscale. We examined the impact of mammoplasty on the satisfaction levels and well-being of women who had undergone RS (after MRM). They were less satisfied with their breasts than those who belonged to the AS group, confirming our hypothesis. However, this was true only among those who had undergone surgery ≤3 years earlier. Conclusions: In conclusion, our findings underscore the need to provide psychological support to those who have undergone breast AS and RS. Additionally, this study implies the need for personalized psychological interventions to improve the emotional adaptation process and enhance women's mental well-being.

Pertussis in Italy: how to protect the "unprotectable"?

Whooping cough continues to be an important public health issue despite high levels of vaccination coverage with acellular pertussis vaccine. Young unimmunized infants represent the most vulnerable group with the highest rates of complications and death. As infant-specific pertussis epidemiologic data, especially among neonates, in Italy were limited, a retrospective observational study of hospitalizations for whooping cough in Italian infants aged <12 months between 2007 and 2018 was conducted to address this knowledge gap. The temporal trend of rates, also stratified for age classes according to the expected age for the administration of vaccine doses, were analyzed by the slope of the regression line. The mean age at the time of admission was 92 d (±64). A clear seasonal pattern in the occurrence of pertussis hospitalizations with a summer peak was observed. Infants younger than 3 months old had the highest hospitalization rates (169 x 100000 infants on average), with a significant rising trend of 9 x 100000 infants on average per year. Limiting the analysis to Bordetella pertussis-related hospitalizations such trend was even more evident. In the other age classes, hospitalization rates were considerably lower and gradually decreased with increasing age. This study demonstrated that pediatric populations, too young to be protected by vaccination, had a greater risk of contracting pertussis. Thus, it is necessary to promote additional immunization strategies besides one booster dose in adolescents, including vaccination during pregnancy.

Laparoscopic sleeve gastrectomy: A role of inflammatory markers in the early detection of gastric leak.

SETTING: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity as a bariatric option. Gastric leak (GL) is the most dreaded septic complication of LSG. Early detection and treatment of this complication may improve outcomes. OBJECTIVES: This study investigates biomarkers that might be useful to predict GL before its clinical presentation in patients who underwent LSG. PATIENTS AND METHODS: This study, prospective observational, was carried out in 151 patients, who underwent LSG for morbid obesity between February 2014 and October 2019. Blood samples were collected before the operation and on post-operative days one, three and five to dose serum C-reactive protein (CRP), pro-calcitonin (PCT), fibrinogen, white blood cells (WBCs) count and neutrophil-to-lymphocyte ratio (NLR). RESULTS: GL occurred in 6 patients (3.97%). According to the receiver operating characteristics curve, NLR detected leak with remarkably higher sensitivity (100%) and specificity (100%) than CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5. Moreover, the area under the curve (AUC) of NLR (AUC = 1) was higher than the AUC of CRP, fibrinogen, WBC on all the days and higher than PCT in post-operative days 3 and 5, suggesting important statistical significance. CONCLUSIONS: Because NLR and PCT detected GL with remarkably higher sensitivity and specificity than CRP, fibrinogen and WBC, these two markers seem to be more accurate for the early detection of this complication.

Associations between COVID-19 Incidence Rates and the Exposure to PM2.5 and NO2: A Nationwide Observational Study in Italy.

The COVID-19 outbreak disproportionately affected the elderly and areas with higher population density. Among the multiple factors possibly involved, a role for air pollution has also been hypothesized. This nationwide observational study demonstrated the significant positive relationship between COVID-19 incidence rates and PM2.5 and NO2 levels in Italy, both considering the period 2016-2020 and the months of the epidemic, through univariate regression models, after logarithmic transformation of the variables, as the data were not normally distributed. That relationship was confirmed by a multivariate analysis showing the combined effect of the two pollutants, adjusted for the old-age index and population density. An increase in PM2.5 and NO2 concentrations by one unit (1 µg/m3) corresponded to an increase in incidence rates of 1.56 and 1.24 × 104 people, respectively, taking into account the average levels of air pollutants in the period 2016-2020, and 2.79 and 1.24 × 104 people during March-May 2020. Considering the entire epidemic period (March-October 2020), these increases were 1.05 and 1.01 × 104 people, respectively, and could explain 59% of the variance in COVID-19 incidence rates (R2 = 0.59). This evidence could support the implementation of targeted responses by focusing on areas with low air quality to mitigate the spread of the disease.

TNM: a simple classification system for complicated intra-abdominal sepsis after acute appendicitis.

BACKGROUND: Delayed diagnosis in case of acute appendicitis (AA) could lead to complicated intra-abdominal sepsis (IAS). Grading systems are not commonly employed in the clinical practice, because they are too complicated or too specific. Therefore, we suggest grading the severity of complicated IAS after AA with a simple system: TNM, an acronym borrowed by cancer staging where T indicates temperature, N neutrophils, and M multiple organ failure (MOF). This prospective observational study evaluates the predictive value of the TNM score on mortality of patients with complicated IAS after AA. METHODS: Sixty-eight patients with complicated IAS after AA were treated. Three classes of attributes were chosen: temperature (T), neutrophils count (N), and MOF (M). After defining the categories T (T0-T4), N (N0-N3) and M (M0-M2), these were grouped in stages (0-IV). Variables analyzed for their possible relation to death were age, sex, temperature, neutrophils count, preoperative organ failure, immunocompromised status, stage (0-IV). Odds ratios were calculated in a univariate and multivariate analysis. RESULTS: TNM staging was: one patient stage 0; 16 patients at stage I; 26 patients at stage II; 16 patients at stage III; nine patients at stage IV. Death occurred in 15 patients (22%). Neutrophil count, preoperative organ failure, immunocompromised status, stages III-IV were potential predictors of postoperative death in univariate analysis; only stage IV was significant independent predictor of postoperative mortality in multivariate analysis. CONCLUSIONS: TNM classification is very easy to use; it helps to define the mortality risk and is useful to objectively compare patients with sepsis.

Analysis of Risk Factors Independently Associated with Cognitive Impairment in Patients with Permanent Atrial Fibrillation: A Cross-sectional Observational Study.

BACKGROUND AND OBJECTIVE: Atrial Fibrillation (AF) is associated with an increased risk of stroke and development of cognitive impairment. Our cross-sectional study aims to identify risk factors for cognitive impairment in patients with permanent AF. MATERIALS AND METHODS: 212 consecutive outpatients with history of permanent AF lasting more than 1 year were enrolled and the Short Portable Mental Status Questionnaire (SPMSQ) was used to assess cognitive impairment (number of errors ≥5). The type of antithrombotic therapy, the time in therapeutic range (TTR) in case of treatment with warfarin and the degree of heart rate (HR) control (upon Holter ECG monitoring) were also assessed. RESULTS: ROC curve analysis indicated that TTR was associated with cognitive impairment (AUC 0.85 ± 0.03; 95% CI 0.77-0.88; p < 0.0001). Multivariate logistic regression analysis showed an independent association of previous cerebrovascular or cardiovascular events (OR 7.24, 95% CI 1.37-38.25; p = 0.020), aspirin therapy instead of anticoagulant therapy (OR 24.74, 95% CI 1.27-482.12; p = 0.034), warfarin use with TTR ≤60% (OR 21.71 , 95%CI 4.35-108; p < 0.001) and an average daily HR either <60 bpm or >100 bpm (OR 6.04, 95% 1.09-33.29; p = 0.039) with cognitive impairment. CONCLUSION: Among patients with permanent AF, cognitive impairment is more frequent in those with inadequate antithrombotic therapy (aspirin therapy instead of anticoagulant therapy) and with suboptimal oral anticoagulation (TTR ≤60%) or heart rate control. Efforts should be made to optimize therapies related to these parameters.

The Effects of Low-Nickel Diet Combined with Oral Administration of Selected Probiotics on Patients with Systemic Nickel Allergy Syndrome (SNAS) and Gut Dysbiosis.

BACKGROUND: Nickel (Ni) oral consumption may elicit systemic reactions in patients affected by systemic nickel allergy syndrome (SNAS), including gastrointestinal symptoms, which in turn are associated with gut dysbiosis. We evaluated the effects of a low-Ni diet alone or in combination with the oral consumption of appropriate probiotics on Ni-sensitivity and urinary dysbiosis markers in SNAS patients. METHODS: n = 51 patients with SNAS and concomitant intestinal dysbiosis were enrolled in the study. According to the urinary indican/skatole levels, quantified through a colorimetric and a high-performance liquid chromatographic method, respectively, patients were assigned to a dysbiosis type/grade and followed a low-Ni diet for three months. Along with the diet, 22 patients also consumed probiotics based on the dysbiosis type. In particular, a Lactobacilli- or Bifidobacteria-containing formulation was administered to patients with fermentative or putrefactive dysbiosis, respectively, while a broad-spectrum probiotic formulation containing both Lactobacilli and Bifidobacteria was administered to patients with mixed dysbiosis. After three months, patients were invited to repeat the Ni-stimulation and the dysbiosis tests. RESULTS: The fermentative dysbiosis group represented the largest group followed by the mixed dysbiosis group, while only two patients had putrefactive dysbiosis. Overall, at three months of treatment in general (diet alone with or without probiotics), the Ni-sensitivity and dysbiosis levels were strongly ameliorated. The association of a low-Ni diet with a specific probiotic oral supplementation was significantly more effective in decreasing dysbiosis levels or reaching eubiosis than with diet alone. CONCLUSION: Our results, while confirming the benefits of a low-Ni diet in SNAS patients, strongly support that appropriate adjuvant treatment with probiotics significantly helps to improve intestinal dysbiosis or restore a healthy microbiota.

Trends in Hospital Admissions for Pertussis Infection: A Nationwide Retrospective Observational Study in Italy, 2002-2016.

Background: Pertussis is a highly contagious infectious disease which continues to be an important public-health issue despite the high immunization coverage rates achieved. However, evidence of increased circulation of pertussis among adolescents and adults due to waning immunity and atypical clinical manifestations seem to be the main reasons for its resurgence. The aim of this study was the analysis of the epidemiological trend for pertussis-related hospitalizations in Italy, in relation with vaccination coverage and information from laboratory confirmed cases of pertussis.Methods: A retrospective observational study investigating hospitalizations for pertussis from 2002 to 2016 in Italy was conducted. Frequencies and rates of hospitalization were analyzed and hospitalization data were compared with a series of already published laboratory confirmed data. Results: This study highlighted a rising trend for pertussis hospitalizations in Italy since 2008. Infants aged <1 year showed the highest frequencies (63.39%) and average rates (74.60 × 100000 infants) of hospitalization despite an extremely high vaccination coverage (95.89%). An increasing trend of hospitalization frequency emerged for the age group with levels of IgG antibodies to pertussis toxin compatible with pertussis infection within the last year (20-29 years old age group). Conclusions: The rising trend for pertussis hospitalizations and the greater involvement of infants aged <1 year require an integrated approach, including the implementation of booster doses administration in adolescence and adulthood, the vaccination of pregnant women and the cocoon strategy.
