This data article provides the methods and procedures followed to collect and analyse soil, vegetation and bird data on three different treatment islands in Guntersville Reservoir, Alabama. Samples ...were collected from randomly selected plot points from islands that were placed into three different treatment types: Colony (currently occupied by Double-crested Cormorants) (Phalacrocorax auritus; n = 5), Historic (historically occupied by cormorants and currently abandoned; n = 3) and Reference (never occupied by cormorants; n = 4). We compared vegetation and tree metrics such as structure and diversity, as well as soil chemistry and bird diversity and communities among islands within Guntersville Reservoir. These data document for the first time that we are aware of the long-term effects of soil chemistry changes, vegetation changes, and impacts to avian diversity, in temperate forest ecosystems, by cormorant colonies. All data is associated with the recent article by Veum et al. 1 and provided here as raw data.
Injuries, the leading cause of death in children 1-17 years old, are often preventable. Injury patterns are impacted by changes in the child's environment, shifts in supervision, and caregiver ...stressors. The objective of this study was to evaluate the incidence and proportion of injuries, mechanisms, and severity seen in Pediatric Emergency Departments (PEDs) during the COVID-19 pandemic.
This multicenter, cross-sectional study from January 2019 through December 2020 examined visits to 40 PEDs for children < 18 years old. Injury was defined by at least one International Classification of Disease-10th revision (ICD-10) code for bodily injury (S00-T78). The main study outcomes were total and proportion of PED injury-related visits compared to all visits in March through December 2020 and to the same months in 2019. Weekly injury visits as a percentage of total PED visits were calculated for all weeks between January 2019 and December 2020.
The study included 741,418 PED visits for injuries pre-COVID-19 pandemic (2019) and during the COVID-19 pandemic (2020). Overall PED visits from all causes decreased 27.4% in March to December 2020 compared to the same time frame in 2019; however, the proportion of injury-related PED visits in 2020 increased by 37.7%. In 2020, injured children were younger (median age 6.31 years vs 7.31 in 2019), more commonly White (54% vs 50%, p < 0.001), non-Hispanic (72% vs 69%, p < 0.001) and had private insurance (35% vs 32%, p < 0.001). Injury hospitalizations increased 2.2% (p < 0.001) and deaths increased 0.03% (p < 0.001) in 2020 compared to 2019. Mean injury severity score increased (2.2 to 2.4, p < 0.001) between 2019 and 2020. Injuries declined for struck by/against (- 4.9%) and overexertion (- 1.2%) mechanisms. Injuries proportionally increased for pedal cycles (2.8%), cut/pierce (1.5%), motor vehicle occupant (0.9%), other transportation (0.6%), fire/burn (0.5%) and firearms (0.3%) compared to all injuries in 2020 versus 2019.
The proportion of PED injury-related visits in March through December 2020 increased compared to the same months in 2019. Racial and payor differences were noted. Mechanisms of injury seen in the PED during 2020 changed compared to 2019, and this can inform injury prevention initiatives.
Abstract
Background
Lynch syndrome is a hereditary cancer disease resulting in an increased risk of colorectal cancer. Herein, findings are reported from an emergency clinical service implemented ...during the COVID-19 pandemic utilizing faecal immunochemical testing (‘FIT’) in Lynch syndrome patients to prioritize colonoscopy while endoscopy services were limited.
Methods
An emergency service protocol was designed to improve colonoscopic surveillance access throughout the COVID-19 pandemic in England for people with Lynch syndrome when services were extremely restricted (1 March 2020 to 31 March 2021) and promoted by the English National Health Service. Requests for faecal immunochemical testing from participating centres were sent to the National Health Service Bowel Cancer Screening South of England Hub and a faecal immunochemical testing kit, faecal immunochemical testing instructions, paper-based survey, and pre-paid return envelope were sent to patients. Reports with faecal haemoglobin results were returned electronically for clinical action. Risk stratification for colonoscopy was as follows: faecal haemoglobin less than 10 µg of haemoglobin/g of faeces (µg/g)—scheduled within 6–12 weeks; and faecal haemoglobin greater than or equal to 10 µg/g—triaged via an urgent suspected cancer clinical pathway. Primary outcomes of interest included the identification of highest-risk Lynch syndrome patients and determining the impact of faecal immunochemical testing in risk-stratified colonoscopic surveillance.
Results
Fifteen centres participated from June 2020 to March 2021. Uptake was 68.8 per cent amongst 558 patients invited. For 339 eligible participants analysed, 279 (82.3 per cent) had faecal haemoglobin less than 10 µg/g and 60 (17.7 per cent) had faecal haemoglobin greater than or equal to 10 µg/g. In the latter group, the diagnostic accuracy of faecal immunochemical testing was 65.9 per cent and escalation to colonoscopy was facilitated (median 49 versus 122 days, χ2 = 0.0003, P < 0.001).
Conclusion
Faecal immunochemical testing demonstrated clinical value for Lynch syndrome patients requiring colorectal cancer surveillance during the pandemic in this descriptive report of an emergency COVID-19 response service. Further longitudinal investigation on faecal immunochemical testing efficacy in Lynch syndrome is warranted and will be examined under the ‘FIT for Lynch’ study (ISRCTN15740250).
This was an emergency service protocol designed to improve access to colonoscopy using faecal immunochemical testing for risk-stratified triage during the height of the COVID-19 pandemic for people with Lynch syndrome when endoscopy services were extremely limited. Requests for faecal immunochemical testing for eligible Lynch syndrome patients were made by participating National Health Service Trusts, which triggered the sending of a faecal immunochemical testing kit, faecal immunochemical testing instructions, a paper-based survey, and pre-paid return envelope from the National Health Service Bowel Cancer Screening South of England Hub in Surrey to said patients, and risk stratification for colonoscopy was as follows: faecal haemoglobin less than 10 µg/g—schedule colonoscopy within 6–12 weeks; and faecal haemoglobin greater than or equal to 10 µg/g—triage via an urgent suspected cancer clinical pathway. For 339 participants analysed, 279 (82.3 per cent) had faecal haemoglobin less than 10 µg/g and 60 (177.0 per cent) met criteria for urgent triage (faecal haemoglobin greater than or equal to 10 µg/g), with escalation to colonoscopy facilitated in the latter group of patients, with a median wait of 49 days (versus 122 days for f-Hb less than 10), demonstrating the clinical value of faecal immunochemical testing for patients with Lynch syndrome requiring colorectal cancer surveillance during the pandemic.
Treatment of plasmid pBR322 with Fe2-(HPTB)(OH)(NO3)4(HPTB=N,N,N',N' -tetrakis(2-benzimidazolylmethyl)-2-hydroxy-1,3-diaminopropane) and H2O2or O2and a reductant (dithiothreitol or ascorbate) results ...in double-stranded cleavage of the plasmid. The linearization of supercoiled pBR322 by this complex is not inhibited by hydroxyl radical scavengers. On the other hand, the linearized pBR322 is efficiently religated by T4 DNA ligase, and the presence of 3'-OH and 5'-OPO3ends is corroborated by 3'- and 5'-end-labeling studies. These observations indicate that cleavage results from hydrolysis of the DNA-phosphate backbone, which is proposed to occur by nucleophilic attack of the bound peroxide on the phosphodiester. Double-stranded cleavage by the Fe2(HPTB)(OH)(NO3)4/H2O2adduct preferentially occurs between bp 3489 and 3485 of pBR322.
