Did the March 2020 lockdown cause an increase in patients presenting to the emergency department with odontogenic pain and infection? A single centre,retrospective analysis

On the 25 March 2020 the Chief Dental Officer (CDO) published guidance to restrict the provision of routine dental care in England due to the rapid spread of the severe acute respiratory syndrome Coronavirus 2 (COVID-19). We analysed the impact of the pandemic on the number of patients presenting with odontogenic pain and infection to the emergency department (ED) of an urban-based teaching hospital, the Bristol Royal Infirmary (BRI). Furthermore, we investigated the severity of infection at first presentation to the ED. The study period encompassed three phases that represented the stages of pandemic restrictions: phase 1 prior to lockdown measures, with no restrictions to dental practice; phase 2 during the government lockdown, with the severest restrictions on dental practices; and phase 3 following the ease of lockdown measures, with return to limited dental services. Data were collected retrospectively from electronic patient records (EPR) regarding adult patients presenting to the ED with dental pain. The rate of presentations (per week) was calculated for each timepoint and compared. A severity score was assigned to each patient using a grading system based on signs of clinical infection and treatment modality. Patients' presentations were analysed at each phase of the pandemic. There was a 42.8% increase in attendance with oral facial pain and infection to ED from phases 1 to 3. The COVID-19 pandemic resulted in restrictions to routine primary dental care services, which were deemed necessary to reduce the spread of the virus. However, this increased demand on secondary care services, as patients increasingly struggled to access primary dental care to manage dental pain.     

Top advances of the year: Precision oncology

The advent of precision medicine has changed the landscape of oncologic biomarkers, drug discovery, drug development, and, more importantly, outcomes for patients with cancer. Precision oncology entails the genomic profiling of tumors to detect actionable aberrations. The advances in clinical next-generation sequencing from both tumor tissue and liquid biopsy and availability of targeted therapies has rapidly entered mainstream clinical practice. In this review, recent major developments in precision oncology that have affected outcomes for patients with cancer are discussed. Rapid clinical development was seen of targeted agents across various mutational profiles such as KRASG12C (which was considered “undruggable” for almost 4 decades), Exon 20 insertions, and RET mutations. Approaches to precision chemotherapy delivery by the introduction of antibody drug conjugates in the armamentarium against lung cancer has been appreciated.     

新冠肺炎“动态清零”常态化下应急梯队护士体验的质性研究

目的 研究新型冠状病毒肺炎常态化疫情防控下应急梯队护士的真实体验。提出针对性改善护士的心理状况的方法和建议。方法 于2021年10月选取上海市静安区闸北中心医院应急梯队的护士11名为研究对象，对其进行半结构式面对面谈话，并采用Colaizzi七步分析法进行资料分析。结果 进入应急梯队的护士普遍存在着紧张焦虑，情绪低落，身心疲惫等心理问题。而执行完应急任务后的成就感，社会的认同，多方的理解支持，有利缓解心理压力。结论 通过对新型冠状病毒肺炎常态化疫情防控下应急梯队护士的真实体验的了解，护士普遍存在各种心理问题，需要给予针对性的干预措施，提高应急梯队成员的心理素质和应急能力。     

Análisis evolutivo de morbimortalidad en cirugía de urgencias durante la pandemia: comparación retrospectiva entre primera y segunda ola de COVID-19

IntroductionSince the beginning of the pandemic, morbidity and mortality in emergency care of surgical patients have been the subject of several studies. However, most of these have compared this variable with that of the pre-COVID period, ignoring its evolution during the pandemic itself. In order to analyze this possible change, we performed a comparative study of morbidity and mortality in emergency surgery between the first and second waves of the pandemic in our center.Material and methodsRetrospective longitudinal study including all patients over the age of 18 admitted and/or operated in the emergency setting in the two maximum incidence periods (MIP) of COVID-19 infection (1st MIP: 22/03/2020–31/05/2020; 2nd MIP: 26/08/2020–30/11/2020). The incidence of SARS-CoV-2 infection, treatment received, early morbidity and mortality and possible risk factors for complications were analyzed.ResultsA total of 173 patients were analyzed (1st MIP: 66; 2nd MIP: 107). The incidence of COVID-19 was higher in the second period (14.95% vs. 4.54%). SARS-CoV-2 infection was associated with a higher rate of complications, however, no statistically significant differences were observed in morbimortality rate, either in the total sample (p = 0.746) or in patients with a positive COVID-19 test (p = 0.582) between both periods. Surgical treatment was found to be associated with a lower complication rate in both the first (p = 0.006) and second wave (p = 0.014), and it was more frequent in the second PMI (70.1 vs. 57.6%) although statistical significance was not reached (p = 0.065).ConclusionsNo significant differences were observed in morbimortality of patients admitted and/or operated in the emergency setting in the two periods of maximum incidence of SARS-CoV-2 in our center. Surgical treatment was associated with a lower morbimortality rate, and it was more frequent in the second MIP.     

自膨式聚氨酯泡沫在致命性出血模型中的应用

目的:在致死性肝创伤大出血动物模型中评价自膨式聚氨酯泡沫（self-expanding polyurethane polymer，SPUP）的止血效果。方法:建立猪致死性肝创伤大出血模型，进行损伤控制性液体复苏，致伤后30 min将实验动物随机（随机数字法）分为纱布填塞组（gauze packing group，GP），泡沫材料填塞组（foam packing group，FP）和对照组（blank control group，BC），每组各6只。监测48 h记录生存时间、生命体征、失血量、凝血功能及血液指标，并于死亡或处死后行肝创面组织病理学检查。结果:建模后三组动物均出现严重的失血性休克，其中FP组、GP组48 h生存率显著高于BC组（6/6 vs 4/6 vs 0/6）。FP组生存时间与GP组差异无统计学意义[48 h vs （44.58±5.53） h， P>0.05],与BC组相比显著延长[48 h vs （1.64±0.17） h， P<0.01]。FP组出血量明显少于GP组和BC组[（19.2±7.3） g/kg vs （41.3±8.6） g/kg、（51.5±7.3） g/kg，均 P<0.01]。与GP组和BC组相比，FP组的心输出量有明显改善[（5.0±0.53） L/min vs （4.13±0.41） L/min、（2.38±0.48） L/min，均 P<0.05]。FP组与GP组凝血功能、肝肾功能及血乳酸水平均好于BC组；FP组膀胱压明显高于GP组[（18.83±3.25） cmH 2O vs （3.83±1.47） cmH 2O, P<0.05, 1 cmH 2O=0.098 kPa]，BC组未见膀胱压异常增高。FP组组织病理学未见明显继发性损伤。 结论:应用SPUP行腹腔填塞止血可以有效减少致死性肝创伤大出血模型的出血量，有效维持生命体征，提高短期生存率。
