Possible Approach to Esophageal Lung with Long Tracheobronchial Gap
Esophageal lung is a rare bronchopulmonary foregut malformation characterized by an anomalous origin of one of the main bronchi which arises from the esophagus. Less than 30 cases are reported in the literature. Therefore, there are no standardized guidelines for the treatment of this condition. We report a case of right esophageal lung diagnosed in a neonate. The patient was treated with thoracoscopic closure of the ectopic main bronchus in the neonatal period, followed by delayed pneumonectomy at 5 months of age. No prosthetic substitute was implanted in the ipsilateral hemithorax after pneumonectomy. The patient is now 4 years old and doing well, postpneumonectomy syndrome was never observed. Our strategy and the possible alternatives are discussed here
Intravenous thrombolysis in the emergency department for the treatment of acute ischaemic stroke
BACKGROUND AND AIMS:
Thrombolytic therapy with intravenous recombinant tissue plasminogen activator (rt-PA) improves outcome in patients with ischaemic stroke treated within 3 h of symptom onset, but its extended implementation is limited. A pilot study was designed to verify whether evaluation of patients with acute ischaemic stroke and their treatment with intravenous rt-PA in the emergency department (ED), followed by transportation to a semi-intensive stroke care unit, offers a safe and effective organisational solution to provide intravenous thrombolysis to acute stroke patients when a stroke unit (SU) is not available.
METHODS:
After checking for inclusion and exclusion criteria, ED doctors contacted the stroke team with a single page, located family members and urgently obtained computed tomography scan and laboratory tests. A stroke team investigator clinically assessed the patient, obtained written informed consent and supervised intravenous rt-PA in the ED. After treatment, the patient was transferred to the SU for rehabilitation and treatment of complications, under supervision of the same stroke team investigator.
RESULTS:
52 patients were treated with intravenous rt-PA within 3 h of symptom onset. 20 patients (38%) improved neurologically after 24 h, the number increased to 30 (58%) after one week. At 3 months 22 patients had a favourable outcome (43%). The 3-month mortality rate was 12%. Symptomatic cerebral haemorrhage was observed in two patients (4%).
CONCLUSIONS:
Intravenous rt-PA administration in the ED is an effective organisational solution for acute ischaemic stroke when an SU is not established
The Clinical Utility of Lower Extremity Dual-Energy CT Angiography in the Detection of Bone Marrow Edema in Diabetic Patients with Peripheral Artery Disease
(1) Background: Type 2 diabetes is a major cause of incidences and the progression of peripheral artery disease (PAD). Bone marrow edema (BME) is an important finding suggestive of underlying bone inflammation in non-traumatic diabetic patients with PAD. Our aim was to evaluate the presence, severity, and clinical implications of BME detected by virtual non-calcium application (VNCa) of dual-energy CT angiography (DE-CTA). (2) Methods: A consecutive series of 76 diabetic patients (55 men; mean age 71.6 ± 11.2 yrs) submitted to lower limb DE-CTA for PAD evaluation and revascularization planning, which were retrospectively analyzed. VNCa images were independently and blindly revised for the presence, location, and severity of BME by two radiologists with 10 years of experience. BME and non-BME groups were evaluated in terms of PAD clinical severity and 6-month secondary major amputation rate. (3) Results: BME was present in 17 (22%) cases, while 59 (78%) patients were non-BME. The BME group showed a significantly higher incidence of major amputation (p < 0.001) and a significantly higher number of patients with advanced clinical stages of PAD compared to the non-BME group (p = 0.024). (4) Conclusions: Lower limb DE-CTA with VNCa application is a useful tool in the detection of BME in diabetic patients with PAD, simultaneously enabling the evaluation of the severity and location of the arterial disease for revascularization planning. BME presence could be a marker of clinically severe PAD and a possible risk factor for revascularization failure
Successful extracorporeal membrane oxygenation after incidental azygos vein cannulation in a neonate with right-sided congenital diaphragmatic hernia interruption of the inferior vena cava and azygos continuation
Incidental azygos vein cannulation has been reported in a few cases of neonatal extracorporeal membrane oxygenation (ECMO). This complication is described in the literature mainly in pathological conditions wherein increased central venous pressure dilates the superior vena cava (SVC), i.e., right congenital diaphragmatic hernia (CDH) or pulmonary hypertension. Azygos vein cannulation should always be suspected in cases of impaired venous return and circuit failure. Although rare, it hinders proper venous aspiration of the ECMO circuit and generally requires repositioning or replacement of the venous cannula or conversion to central cannulation. In this report, we describe a newborn with severe right CDH who required ECMO assistance, wherein incidental cannulation of the azygos vein resulted in successful functioning of the circuit because of the concomitant presence of isolated interruption of the inferior vena cava and azygos continuation. To the best of our knowledge, this is the first report of successful neonatal ECMO despite azygos vein cannulation in a patient with such rare physiology
Staphylococcus aureus colonization and risk of surgical site infection in children undergoing clean elective surgery: A cohort study
Staphylococcus aureus persistently colonizes the skin and nasopharynx of approximately 20% to 30% of individuals, with the highest rates in younger children. To avoid clinical problems for carriers and the spread of S aureus to other hospitalized patients, screening and decolonization of carriers undergoing surgery has been recommended. However, the best approach to patients undergoing clean surgery is not precisely defined. To evaluate whether children carrying S aureus admitted to the hospital for clean elective surgery have an increased risk of postoperative surgical infections, 393 infants and children (77.1% males; mean age\u200a\ub1\u200astandard deviation, 7.6\u200a\ub1\u200a4.5 years) who were scheduled for clean elective surgery procedures were evaluated for S aureus carriage on the day of intervention and 5 days after it. Both anterior nares and pharyngeal swabs were collected. S aureus was identified using the RIDAGENE methicillin-resistant S aureus (MRSA) system (R-Biopharm AG, Darmstadt, Germany), according to the manufacturer's instructions. At admission, 138 (35.1%) children screened positive for S aureus. MRSA was identified in 40 (29.0% of S aureus positive subjects) cases. The carriage rates of S aureus and MRSA varied considerably with age, and in children <2 years old the rate was significantly lower than in any other age group (P\u200a<\u200a.05). Surgical site infection was demonstrated in 4 out of 109 (3.7%) children who were initially colonized by S aureus and in 5 out of 201 (2.5%) children with a negative screening, without any statistically significant difference between groups (P\u200a=\u200a.72). None of these children had MRSA. These results seem to suggest that children undergoing clean elective surgery do not need to be screened for S aureus colonization because, although positive, they have no increased risk of surgical site infection. Following this statement, preoperative procedures should be simplified with relevant advantages from a clinical, social, and economic point of view
A maChine and deep Learning Approach to predict pulmoNary hyperteNsIon in newbornS with congenital diaphragmatic Hernia (CLANNISH): Protocol for a retrospective study
Introduction Outcome predictions of patients with congenital diaphragmatic hernia (CDH) still have some limitations in the prenatal estimate of postnatal pulmonary hypertension (PH). We propose applying Machine Learning (ML), and Deep Learning (DL) approaches to fetuses and newborns with CDH to develop forecasting models in prenatal epoch, based on the integrated analysis of clinical data, to provide neonatal PH as the first outcome and, possibly: Favorable response to fetal endoscopic tracheal occlusion (FETO), need for Extracorporeal Membrane Oxygenation (ECMO), survival to ECMO, and death. Moreover, we plan to produce a (semi)automatic fetus lung segmentation system in Magnetic Resonance Imaging (MRI), which will be useful during project implementation but will also be an important tool itself to standardize lung volume measures for CDH fetuses. Methods and analytics Patients with isolated CDH from singleton pregnancies will be enrolled, whose prenatal checks were performed at the Fetal Surgery Unit of the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico (Milan, Italy) from the 30th week of gestation. A retrospective data collection of clinical and radiological variables from newborns' and mothers' clinical records will be performed for eligible patients born between 01/01/2012 and 31/12/2020. The native sequences from fetal magnetic resonance imaging (MRI) will be collected. Data from different sources will be integrated and analyzed using ML and DL, and forecasting algorithms will be developed for each outcome. Methods of data augmentation and dimensionality reduction (feature selection and extraction) will be employed to increase sample size and avoid overfitting. A software system for automatic fetal lung volume segmentation in MRI based on the DL 3D U-NET approach will also be developed. Ethics and dissemination This retrospective study received approval from the local ethics committee (Milan Area 2, Italy). The development of predictive models in CDH outcomes will provide a key contribution in disease prediction, early targeted interventions, and personalized management, with an overall improvement in care quality, resource allocation, healthcare, and family savings. Our findings will be validated in a future prospective multicenter cohort study
Guideline Application in Real world: multi-Institutional Based survey of Adjuvant and first-Line pancreatic Ductal adenocarcinoma treatment in Italy. Primary analysis of the GARIBALDI survey
Background: Information about the adherence to scientific societies guidelines in the ‘real-world’ therapeutic
management of oncological patients are lacking. This multicenter, prospective survey was aimed to improve the
knowledge relative to 2017-2018 recommendations of the Italian Association of Medical Oncology (AIOM).
Patients and methods: Treatment-naive adult patients with pancreatic adenocarcinoma were enrolled. Group A
received adjuvant therapy, group B received primary chemotherapy, and group C had metastatic disease. The results
on patients accrued until 31 October 2019 with a mature follow-up were presented.
Results: Since July 2017, 833 eligible patients of 923 (90%) were enrolled in 44 Italian centers. The median age was 69
years (range 36-89 years; 24% >75 years); 48% were female; 93% had Eastern Cooperative Oncology Group (ECOG)
performance status (PS) score of 0 or 1; group A: 16%, group B: 30%; group C: 54%; 72% Nord, 13% Center, 15%
South. In group A, guidelines adherence was 68% [95% confidence interval (CI) 59% to 76%]; 53% of patients
received gemcitabine and 15% gemcitabine þ capecitabine; median CA19.9 was 29 (range 0-7300; not reported
15%); median survival was 36.4 months (95% CI 27.5-47.3 months). In group B, guidelines adherence was 96% (95%
CI 92% to 98%); 55% of patients received nab-paclitaxel þ gemcitabine, 27% FOLFIRINOX, 12% gemcitabine, and 3%
clinical trial; median CA19.9 was 337 (range 0-20220; not reported 9%); median survival was 18.1 months (95% CI
15.6-19.9 months). In group C, guidelines adherence was 96% (95% CI 94% to 98%); 71% of patients received nabpaclitaxel þ gemcitabine, 16% gemcitabine, 8% FOLFIRINOX, and 4% clinical trial; liver and lung metastases were
reported in 76% and 23% of patients, respectively; median CA19.9 value was 760 (range 0-1374500; not reported
9%); median survival was 10.0 months (95% CI 9.1-11.1 months).
Conclusions: The GARIBALDI survey shows a very high rate of adherence to guidelines and survival outcome in line with
the literature. CA19.9 testing should be enhanced; nutritional and psychological counseling represent an unmet need.
Enrollment to assess adherence to updated AIOM guidelines is ongoing
Germinal BRCA1-2 pathogenic variants (gBRCA1-2pv) and pancreatic cancer: epidemiology of an Italian patient cohort
Objective: Germline BRCA1-2 pathogenic variants (gBRCApv) increase the risk of pancreatic cancer and predict for
response to platinating agents and poly(ADP-ribose) polymerase inhibitors. Data on worldwide gBRCApv incidence
among pancreatic ductal adenocarcinoma (PDAC) patients are sparse and describe a remarkable geographic
heterogeneity. The aim of this study is to analyze the epidemiology of gBRCApv in Italian patients.
Materials and methods: Patients of any age with pancreatic adenocarcinoma, screened within 3 months from diagnosis
for gBRCApv in Italian oncologic centers systematically performing tests without any selection. For the purposes of our
analysis, breast, ovarian, pancreas, and prostate cancer in a patient’s family history was considered as potentially BRCAassociated. Patients or disease characteristics were examined using the c2 test or Fisher’s exact test for qualitative
variables and the Student's t-test or ManneWhitney test for continuous variables, as appropriate.
Results: Between June 2015 and May 2020, 939 patients were tested by 14 Italian centers; 492 (52%) males, median
age 62 years (range 28-87), 569 (61%) metastatic, 273 (29%) with a family history of potentially BRCA-associated
cancers. gBRCA1-2pv were found in 76 patients (8.1%; 9.1% in metastatic; 6.4% in non-metastatic). The gBRCA2/
gBRCA1 ratio was 5.4 : 1. Patients with gBRCApv were younger compared with wild-type (59 versus 62 years,
P ¼ 0.01). The gBRCApv rate was 17.1% among patients <40 years old, 10.4% among patients 41-50 years old,
9.2% among patients 51-60 years old, 6.7% among patients aged 61-70 years, and 6.2% among patients >70 years
old (none out of 94 patients >73 years old). gBRCApv frequency in 845 patients <74 years old was 9%. Patients
with/without a family history of potentially BRCA-associated tumors had 14%/6% mutations.
Conclusion: Based on our findings of a gBRCApv incidence higher than expected in a real-life series of Italian patients
with incident PDAC, we recommend screening all PDAC patients <74 years old, regardless of family history and stage,
due to the therapeutic implications and cancer risk prevention in patients' relatives.

Nerve Growth Factor Promotes Gastric Tumorigenesis through Aberrant Cholinergic Signaling
Within the gastrointestinal stem cell niche, nerves help to regulate both normal and neoplastic stem cell dynamics. Here, we reveal the mechanisms underlying the cancer-nerve partnership. We find that Dclk1+ tuft cells and nerves are the main sources of acetylcholine (ACh) within the gastric mucosa. Cholinergic stimulation of the gastric epithelium induced nerve growth factor (NGF) expression, and in turn NGF overexpression within gastric epithelium expanded enteric nerves and promoted carcinogenesis. Ablation of Dclk1+ cells or blockade of NGF/Trk signaling inhibited epithelial proliferation and tumorigenesis in an ACh muscarinic receptor-3 (M3R)-dependent manner, in part through suppression of yes-associated protein (YAP) function. This feedforward ACh-NGF axis activates the gastric cancer niche and offers a compelling target for tumor treatment and prevention
Chemotherapy toxicity and activity in patients with pancreatic ductal adenocarcinoma and germline BRCA1-2 pathogenic variants (gBRCA1-2pv): a multicenter survey
Background: Germline BRCA1-2 pathogenic variants (gBRCA1-2pv)-related pancreatic ductal adenocarcinoma (PDAC) showed increased sensitivity to DNA cross-linking agents. This study aimed at exploring safety profile, dose intensity, and activity of different chemotherapy regimens in this setting.Patients and methods: gBRCA1-2pv PDAC patients of any age and clinical tumor stage who completed a first course of chemotherapy were eligible. A descriptive analysis of chemotherapy toxicity, dose intensity, response, and survival outcomes was performed.Results: A total of 85 gBRCA1-2pv PDAC patients treated in 21 Italian centers between December 2008 and March 2021 were enrolled. Seventy-four patients were assessable for toxicity and dose intensity, 83 for outcome. Dose intensity was as follows: nab-paclitaxel 72%, gemcitabine 76% (AG); cisplatin 75%, nab-paclitaxel 73%, capecitabine 73%, and gemcitabine 65% (PAXG); fluorouracil 35%, irinotecan 58%, and oxaliplatin 64% (FOLFIRINOX). When compared with the literature, grade 3-4 neutropenia, thrombocytopenia, and diarrhea were increased with PAXG, and unmodified with AG and FOLFIRINOX. RECIST responses were numerically higher with the three-(81%) or four-drug (73%) platinum-containing regimens that outperformed AG (41%) and oxaliplatin-based doublets (56%). Carbohydrate antigen 19.9 (CA19.9) reduction >89% at nadir was reported in two-third of metastatic patients treated with triplets and quadruplets, as opposed to 33% and 45% of patients receiving oxaliplatin-based doublets or AG, respectively. All patients receiving AG experienced disease progression, with a median progression-free survival (mPFS) of 6.4 months, while patients treated with platinum-containing triplets or quadruplets had an mPFS >10.8 months. Albeit still immature, data on overall survival seemed to parallel those on PFS.Conclusions: Our data, as opposed to figures expected from the literature, highlighted that platinum-based regimens provoked an increased toxicity on proliferating cells, when dose intensity was maintained, or an as-expected toxicity, when dose intensity was reduced, while no change in toxicity and dose intensity was evident with AG. Furthermore, an apparently improved outcome of platinum-based triplets or quadruplets over other regimens was observed
