Scoping Review-The Association between Asthma and Environmental Chemicals

Asthma is one of the most common chronic diseases worldwide affecting all age groups from children to the elderly. In addition to other factors such as smoking, air pollution and atopy, some environmental chemicals are shown or suspected to increase the risk of asthma, exacerbate asthma symptoms and cause other respiratory symptoms. In this scoping review, we report environmental chemicals, prioritized for investigation in the European Human Biomonitoring Initiative (HBM4EU), which are associated or possibly associated with asthma. The substance groups considered to cause asthma through specific sensitization include: diisocyanates, hexavalent chromium Cr(VI) and possibly p-phenylenediamine (p-PDA). In epidemiological studies, polyaromatic hydrocarbons (PAHs) and organophosphate insecticides are associated with asthma, and phthalates, per- and polyfluoroalkyl substances (PFASs), pyrethroid insecticides, mercury, cadmium, arsenic and lead are only potentially associated with asthma. As a conclusion, exposure to PAHs and some pesticides are associated with increased risk of asthma. Diisocyanates and Cr(VI) cause asthma with specific sensitization. For many environmental chemicals, current studies have provided contradicting results in relation to increased risk of asthma. Therefore, more research about exposure to environmental chemicals and risk of asthma is needed.Peer reviewe

A pilot study on the application of the current European guidelines for the management of acute coronary syndrome without elevation of ST segment (NSTEMI) in the Emergency Department setting in the Italian region Lazio.

Background: In 2011 the European Society of Cardiology published the new guidelines for the treatment and management of acute coronary syndrome without elevation of the ST segment (NSTEMI). For the treatment of the syndrome, the use of P2Y12 inhibitors in addition to aspirin was strongly recommended (evidence IA). We studied the application of this recommendation in the setting of the emergency department in the vast and uneven area of the Italian region Lazio, three years after the release of these drugs in Italy. Methods: 121 consecutive patients (65% older than 65 years) affected by NSTEMI were recruited between May and July 2013. During the transition in the emergency department data was collected on patient's symptoms, syndrome severity and type & timing of treatments chosen. Adherence to the guidelines was evaluated considering the number of "good treated" patients: these being the patients that received at least 80% of the main five recommendations on percutaneous coronary intervention (PCI) timing, antiplatelet and anti-coagulant therapy suggested by the European Cardiology Task Force (ESC guidelines, 2011) for the very acute phase of NSTEMI. Results: Patients were treated with: 1) 35% of cases with double antiplatelet therapy and anticoagulation (DAPT+AC), 2) 22% of cases with single antiplatelet and anticoagulation (SAPT+AC), 3) 6% of cases with a single antiplatelet therapy (SAPT), 4) 6% of cases with a double antiplatelet therapy (DAPT) and 5) 24% of cases did not receive any therapy. Data on PCI was available for 95 patients and, of these, only 82% of the patients underwent the procedure. The percentage of "good treated" patients were among of 20-40%, depending on PCI timing – as guidelines suggested – was considered as mandatory (20,5%) or as the extreme time limit (40%). Significant differences were found between patients treated in a central hospital with a hemodynamic laboratory active 24/24hr (HUB) and patients treated in the other hospital (SPOKE). HUBs showed a higher percent of "good treated" patients, a higher percentage of early invasive treated and a better adherence to recommended pharmacological therapy. Conclusions: A significant number of patients did not receive adequate treatment during the emergency department stay. The absence of hemodynamic services increases the risk of inadequate treatment

Pathology reporting in neuroendocrine neoplasms of the digestive system: everything you always wanted to know but were too afraid to ask

During the 5th NIKE (Neuroendocrine tumors Innovation in Knowledge and Education) meeting, held in Naples, Italy, in May 2019, discussions centered on the understanding of pathology reports of gastroenetropancreactic neuroendocrine neoplasms. In particular, the main problem concerned the difficulty that clinicians experience in extrapolating relevant information from neuroendocrine tumor pathology reports. During the meeting, participants were asked to identify and rate issues which they have encountered, for which the input of an expert pathologist would have been appreciated. This article is a collection of the most rated questions and relative answers, focusing on three main topics: 1) morphology and classification; 2) Ki67 and grading; 3) immunohistochemistry. Patient management should be based on multidisciplinary decisions, taking into account clinical and pathology-related features with clear comprehension between all health care professionals. Indeed, pathologists require clinical details and laboratory findings when relevant, while clinicians require concise and standardized reports. In keeping with this last statement, the minimum requirements in pathology datasets are provided in this paper and should be a baseline for all neuroendocrine tumor professionals

Commentary: Case Report: Abdominal Lymph Node Metastases of Parathyroid Carcinoma: Diagnostic Workup, Molecular Diagnosis, and Clinical Management

In the issue of March 2021, Lenschow et al. reported the case of a 46-year-old woman with recurrent, programmed death-ligand-1 (PD-L1) negative, tumor mutational burden (TMB)-high parathyroid carcinoma (PC), who showed stable disease as her best response on imaging, and a three-fold drop in PTH after treatment with intravenous pembrolizumab. Given the remarkable results obtained by Lenschow et al. with the anti-PD-1 agent pembrolizumab in the above-mentioned case, we performed an extensive search for possible further relevant data sources, including a) full published articles in international online databases (PubMed, Web of Science, Scopus, and Embase); b) preliminary reports in selected international meeting abstract repositories (American Society of Clinical Oncology, ASCO; European Neuroendocrine Tumor Society, ENET; European Society for Medical Oncology, ESMO); c) registered clinical trials in the U.S. National Institutes of Health registry of clinical trials (http://clinicaltrials.gov) and in any primary register of the WHO International Clinical Trials Registry Platform (ICTRP)

The undefined anatomical variations of the deltoid ligament bundles: A cadaveric study

Introduction: Recently, Cromeens proposed a new interpretation of the deltoid ligament (DL) using its attachment sites to define individual components. The aim of this cadaveric study was to evaluate the reproducibility of this new classification and investigate anatomical variations of the ligament to contribute to reaching an evidencebased consensus regarding its ligamentous constituent bands, their origins and insertions. Methods: The classification was applied to study only four components of the DL: the tibiocalcaneonavicular (TCN), the superficial posterior tibiotalar (sPTT), the deep anterior tibiotalar (dATT) and the deep posterior tibiotalar (dPTT) ligaments. Fifteen fresh frozen ankles were dissected and the deltoid ligament components defined by their attachment sites and measured on the three axes. Results: The TCN, sPTT and dPTT ligaments were identified in all of the specimens. The TCN was the widest and longest ligament with variable thickness. The sPTT ligament was the second thicker and longer. The dATT ligament, the smaller and thinner, was not identified in 3 specimens. The dPTT ligament was the second wider, which in 3 cadavers presented an accessory bundle, the deep intermedial tibiotalar ligament (dITT ligament). Conclusions: Cromeens's attachment-based classification was proved to be simple, rational and reproducible in allowing the methodological description of the different bands of the DL. Our findings showed that the dITT ligament must be considered a secondary bundle of the dPTT ligament, which was not always identified in all specimens
