In December 2019, an initial cluster of interstitial bilateral pneumonia emerged in Wuhan, China. A human-to-human transmission was assumed and a previously unrecognized entity, termed coronavirus disease-19 (COVID-19) due to a novel coronavirus (SARS-CoV-2) was described. The infection has rapidly spread out all over the world and Italy has been the first European country experiencing the endemic wave with unexpected clinical severity in comparison with Asian countries. It has been shown that SARS-CoV-2 utilizes angiotensin converting enzyme 2 (ACE2) as host receptor and host proteases for cell surface binding and internalization. Thus, a predisposing genetic background can give reason for interindividual disease susceptibility and/or severity. Taking advantage of the Network of Italian Genomes (NIG), here we mined whole-exome sequencing data of 6930 Italian control individuals from five different centers looking for ACE2 variants. A number of variants with a potential impact on protein stability were identified. Among these, three more common missense changes, p.(Asn720Asp), p.(Lys26Arg), and p.(Gly211Arg) were predicted to interfere with protein structure and stabilization. Rare variants likely interfering with the internalization process, namely p.(Leu351Val) and p.(Pro389His), predicted to interfere with SARS-CoV-2 spike protein binding, were also observed. Comparison of ACE2 WES data between a cohort of 131 patients and 258 controls allowed identifying a statistically significant (P value < 0.029) higher allelic variability in controls compared with patients. These findings suggest that a predisposing genetic background may contribute to the observed interindividual clinical variability associated with COVID-19, allowing an evidence-based risk assessment leading to personalized preventive measures and therapeutic options.
Foreign body (FB) aspiration/inhalation is a serious problem because it is still a cause of death in children, especially among those younger than 4 years. The objective of this paper is to characterize the risk of complications and prolonged hospitalization due to foreign bodies (FB) in the upper airways in terms of the characteristics of the injured patients (age, gender), typology and features of the FBs, the circumstances of the accident and the hospitalization details. A retrospective study in the major hospitals of 19 European countries was realized on injuries occurred in the years 2000-2002 and identified by means of the International Classification of Diseases, Ninth Revision (ICD-9) codes listed on hospital discharge records. In 170 cases, it was reported an injury due to the presence of a FB in the pharynx and larynx (ICD933) and in 552 records, it was reported a FB located in the trachea, bronchi and lungs (ICD934). Unlike the complications that occurred in 70 (12.7%) of cases, the hospitalizations were present in 433 (77.6) of the total injuries. One patient died. A higher incidence in males (63%) was observed. Median age for children who experienced complications was 2 years. The most common FB removal technique was laryngoscopy and bronchoscopy. In majority of the cases, children were treated by ENT department. The most common FBs were nuts, seeds, berries, corn and beans. In general, small, round crunchy foods pose a risk of choking. Since prevention is the most essential key to deal with these types of injuries, more effort in caregivers' public education is warranted.
Background: In young children, particularly those aged 1-3 years, aerodigestive tract foreign bodies (FB) are a common pediatric problem. The aim of the present study was therefore to characterize the risk of complications and prolonged hospitalization due to FB in the upper digestive tract in terms of the characteristics of the injured patients (age, gender), typology and features of the FB, the circumstances of the accident and hospitalization details. Methods: A retrospective study was done in 19 hospitals in 19 corresponding European countries of 186 cases of injury due to the presence of an FB in the mouth, esophagus and stomach (ICD935), out of the 2103 overall cases of FB reported in other locations. Results:Complications arose in 14 cases and hospitalization was required in 164 cases. No deaths were observed.Ahigher incidence of hospitalization in male patients (61%) was observed. Median age for children who experienced complications was 2 years old. The most common FB removal technique was esophagoscopy. In the majority of cases the children were treated by the ENT Department. The most common FB were coins, batteries and fish bones among food. Conclusion:Because batteries, as well as coins and fish bones among food were the most common type of FB encountered, and because recent development of technology has accelerated broad use of disk-type batteries, parents should be aware of this hazard, and an educational campaign for public education for this serious problem is advisable.
Data availabilitySummary statistics generated by COVID-19 Host Genetics Initiative are available online (https://www.covid19hg.org/results/r6/). The analyses described here use the freeze 6 data. The COVID-19 Host Genetics Initiative continues to regularly release new data freezes. Summary statistics for samples from individuals of non-European ancestry are not currently available owing to the small individual sample sizes of these groups, but the results for 23 loci lead variants are reported in Supplementary Table 3. Individual-level data can be requested directly from the authors of the contributing studies, listed in Supplementary Table 1.
Objective: The occurrence of foreign bodies (FBs) in otorhinolaryngological practice is a common and serious problem among patients in paediatric age. The aim of this work is to characterize the risk of complications and prolonged hospitalization due to foreign bodies in ears in terms of the characteristics of the injured patients (age, gender), typology and features of the foreign bodies, the circumstances of the accident and the hospitalization's details. Methods: A retrospective study in major hospitals of 19 European countries was realized on children aged 0-14 with regard to the characteristics of the injured child and the FB, the circumstances of the accident and finally the hospitalization's details. Results: Four hundred and ninety eight cases were reported with an injury due to insertion of a FB in the ear (ICD931). Complications were observed in 65 (13.05%) children. Complications were lesion of auricular canal, perforation of tympanic membrane, local inflammation, bleeding, pain and otitis. Hospitalization lasted in median 1 day. The 82% of hospitalized children are in the ''day hospital'' regimen. The spherical, rigid and inorganic FB caused hospitalization in 61%, 63% and 84% of cases, respectively. Conclusion: Foreign body injuries in the ears are commonly encountered in clinical practice. The removal by non-ENT personnel can be associated to complications especially in children who have a variable level of cooperation.Occasions for the injury were mostly playing in the absence of watchful caregivers. Since prevention is the most essential way to deal with FB injuries public education should be encouraged. #
