Association between medically diagnosed postnatal infection and childhood cancers: A matched case-control study in Denmark, 1978 to 2016

Although the association between infection and childhood cancer has been long investigated, there is limited information on rarer cancers. This article aimed to explore the association between postnatal infection and childhood cancers in the Danish population. A matched case-control study was conducted using Danish nationwide registries from 1978 to 2016. Each childhood cancer case was matched 1:25 with controls by birth date within a week and sex. Postnatal infections were identified from the Danish National Patient Registry, which lists diagnoses seen in hospital, specialist or emergency care services. Multivariable conditional logistic regression was used to estimate adjusted odds ratios (adj.OR) and 95% confidence intervals (CI). Specific types of infections and the number of infection episodes were also considered. The study included 4125 childhood cancer cases and 103 526 matched controls with ages ranging from 0 to 19 years. Medically diagnosed postnatal infections were positively associated with many types of childhood cancer including acute lymphoblastic leukemia (adj.OR = 1.42; 95% CI: 1.23-1.63), acute myeloid leukemia (adj.OR = 1.80; 95% CI: 1.28-2.52), non-Hodgkin lymphoma (adj.OR = 1.53; 95% CI: 1.19-1.97) and central nervous system tumors (adj.OR = 1.57; 95% CI: 1.39-1.77). A higher number of infection episodes were also associated with an increased risk of these cancers. Specific infections such as viral, enteric and urinary tract infections were also strongly associated with specific types of cancer. In conclusion, children who later develop cancer appear to have adverse reactions to infections necessitating referral to specialized health care services, perhaps indicating dysregulated immune function.     

中度稳定期慢性阻塞性肺疾病疲劳与多维度指标的关系

目的 探讨中度稳定期慢性阻塞性肺疾病(慢阻肺)患者疲劳与营养指标、生活质量指标、炎症指标、精神情绪指标的关系。方法 采用前瞻性研究,根据一般疲劳定义,从慢阻肺患者中随机选取中度稳定期慢阻肺疲劳患者30例(疲劳组)与中度稳定期慢阻肺非疲劳患者26例(非疲劳组)。收集两组一般资料、营养指标、生活质量指标、炎症指标、精神情绪指标,并进行比较。结果 两组性别、年龄、吸烟指数等方面差异无统计学意义(均P>0.05);与非疲劳组相比,疲劳组白蛋白、血红蛋白、体重指数、第1秒用力呼气容积占预计值的百分比(percent predicted forced expiratory volume in one-second, FEV1%)、6 min步行距离(6-minute walk distance, 6MWD)均显著降低(P<0.05),慢性阻塞性肺疾病评估测试(chronic obstructive pulmonary disease assessment test, CAT)评分、C反应蛋白(C-reactive protein, CRP)、降钙素原(procalcitonin, PCT)、白细胞(WBC)计数、贝克抑郁和焦虑量表评分, 心理身体紧张松弛测试量表(PSTR)评分均较高(P<0.05)。 结论 疲劳与中度稳定期慢阻肺患者营养、生活质量、炎症、精神情绪有关,是建立慢阻肺患者多维度疲劳测量的重要部分。     

慢阻肺急性加重期患者延迟就医与家庭动力学的相关性研究

目的研究慢阻肺急性加重期患者延迟就医与家庭动力学的相关性,希望能够为慢阻肺急性加重期患者拟定护理措施提供科学依据。方法选取2017年1月-2019年12月我院240例诊断为慢阻肺急性加重期的患者为研究对象。根据患者入院就医的时间进行分组,时间≥24h的延迟就医的患者为观察组,时间<24h的及时就医患者为对照组。结果两组患者在文化水平、家庭年收入、在职状态、医疗保险和婚姻状况和APACHEⅡ评分比较(P<0.05)。观察组患者疾病观念、个性化、系统逻辑和家庭氛围得分比对照组高(P<0.05)。Pearman的相关性分析结果显示:慢阻肺急性加重期患者延迟就医时间与各个层面分数以及家庭动力总分呈现负相关性(P<0.05)。应变量为延迟就医为应变量,患者的一般资料为自变量,经Logistic回归分析结果表明:延迟就医的影响因素为文化水平、家庭动力评分、职业状态、家庭收入、婚姻状况和APACHEⅡ评分。结论慢阻肺急性加重期患者家庭动力总分与疾病观念、个性化、系统逻辑和家庭氛围得分与延迟就医时间呈现负相关性,患者延迟就医的影响因素是家庭动力学评分。     

Pulmonary Hypertension Registry of Kerala,India (PRO-KERALA): One-year outcomes

BackgroundShort term outcomes of patients with pulmonary hypertension are not available from low and middle-income countries including India.MethodsWe conducted a prospective study of 2003 patients with pulmonary hypertension, from 50 centres (PROKERALA) in Kerala, who were followed up for one year. Pulmonary hypertension (PH) was mainly diagnosed on the basis of Doppler echocardiography. The primary outcome was a composite end-point of all-cause death and hospital admission for heart failure. All cause hospitalisation events constituted the secondary outcome.ResultsMean age of study population was 56 ± 16 years. Group 1 and Group 2 PH categories constituted 21.2% and 59% of the study population, respectively. Nearly two-thirds (65%) of the study participants had functional class II symptoms. 31% of Group 1 PH patients were on specific vasodilator drugs.In total, 83 patients (4.1%) died during the one-year follow-up period. Further, 1235 re-hospitalisation events (61.7%) were reported. In the multivariate model, baseline NYHA class III/IV (OR 1.87, 95% C.I. 1.35–2.56), use of calcium channel blockers (OR 0.18, 95% C.I. 0.04–0.77), vasodilator therapy (OR 0.5, 95% C.I. 0.28–0.87) and antiplatelet agents (OR 1.80, 95% C.I. 1.29–2.51) were associated with primary composite outcome at one-year (p < 0.05).ConclusionIn the PROKERALA registry, annual mortality rate was 4%. More than half of the patients reported re-hospitalisation events on follow up. Uptake of guideline directed therapies were suboptimal in the study population. Quality improvement programmes to improve guideline directed therapy may improve clinical outcomes of PH patients in India.     

Biomedical waste disposal practices among healthcare workers during COVID-19 pandemic in secondary and tertiary care facilities of Tamil Nadu

PurposeThe ongoing COVID-19 crisis has drastically changed the practice of biomedical waste (BMW) generation and management. Studies venturing into the facility level preparedness at various levels of healthcare delivery during pandemic situation is the need of the hour. Hence, we did this study to assess the BMW disposal practices amongst secondary and tertiary health facilities during COVID-19 pandemic in Tamil Nadu.Materials and methodsThis cross-sectional survey was conducted amongst doctors, nurses and allied healthcare staffs across various departments in 18 public health facilities across six districts of Tamil Nadu. Multivariable logistic regression analysis was done based on the random-intercept model to assess the determinants of BMW disposal practices. The effect size was reported as adjusted odds ratio (aOR) with 95% confidence interval (CI).ResultsIn total, 2593 BMW disposal observations were made. During nearly three-fourth of the observations (73%), the BMW was disposed of appropriately. Nurses (aOR ?= ?1.54; 95%CI: 1.06–2.23) and doctors (aOR ?= ?1.60; 95%CI: 1.05–2.45), healthcare workers in Paediatrics department (aOR ?= ?1.77; 95%CI: 1.13–2.76), healthcare workers in inpatient department (aOR ?= ?2.77; 95%CI: 1.95–3.94) and injection outpatient department (aOR ?= ?2.69; 95%CI: 1.59–4.47) had significantly better odds of having appropriate BMW disposal practices.ConclusionOur study shows that nearly during three-fourth of the observations, healthcare workers performed appropriate BMW disposal practices. However, measures should be taken to achieve 100% compliance by healthcare workers especially the target groups identified in our study by allocating appropriate resources and periodically monitor the BMW disposal practices.     

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.
