The Impact

Background Accumulation of mucous secretions in an endotracheal tube (ETT) increases its resistance, and the amount of deposit may be affected by the quality of humidification and heating of the inspired gas. Methods The authors assessed the impact of two humidification systems, a heated humidifier (HH) and a hygroscopic-hydrophobic heat and moisture exchanger (HME), on the ETT patency in patients selected to require mechanical ventilation for more than 48 h. This comparison was performed over two consecutive periods and used the acoustic reflection method, which characterizes the amount and site of ETT obstruction and allows estimating ETT inner volume and resistance. Measurements were performed three times a week over the period of mechanical ventilation. Comparisons were performed at mid duration and at the end of the mechanical ventilation period. Results The HH was used in 34 patients, and the HME was used in 26 patients. The two groups had similar severity and duration of mechanical ventilation. At mid duration of mechanical ventilation (5.5 +/- 3.3 vs. 4.8 +/- 3.3 days; P = 0.4), no difference was observed in ETT volume and resistance between the two groups. At the end of the study period (10.5 +/- 5.8 vs. 9.6 +/- 6.3 days of mechanical ventilation; P = 0.4), ETT volume was reduced to a greater extent with HME than with HH (-3.3 +/- 2.9 vs. -5.1 +/- 2.5%; P = 0.008), and ETT resistance increased significantly more with the HME than with the HH (8.4 +/- 12.2 vs. 19.4 +/- 17.7%; P = 0.001). Conclusion Prolonged use of humidification systems results in progressive reduction of ETT patency, and to a greater extent with HMEs than with HHs.

The Impact

Introduction: Research into the long-term effects of coronavirus disease 2019 (COVID-19) continues at an unprecedented pace. Many physical long-term symptoms of COVID-19 have been reported and include headache, fatigue, muscle pain and breathlessness, etc. Psychological effects are not dissimilar to survivors of SARS. There is limited qualitative research exploring the mental health impacts and experiences of hospitalized COVID-19 inpatients. Methods: A prospective qualitative study is planned to explore patient experiences post hospital discharge following a diagnosis of COVID-19. The research aims to gain an understanding of how COVID-19 affects quality of life (QoL) and functional abilities. Patients discharged from the hospital will be invited to take part in semi-structured interviews discussing their experiences of hospitalization and the impact of COVID-19 on their QoL. Interviews will be conducted at three and six months following discharge from hospital. This study will provide important qualitative insight and may inform clinical interventions and commissioning decisions. Trial registration: The study has Research Ethics Committee (REC) and Health Research Authority (HRA) approvals obtained from Health and Care Research Wales (HCRW) [IRAS project ID 293196].

Cvd Mortality

Cardiovascular diseases (CVDs) remain the leading cause of death worldwide and significantly affect patient quality of life and socioeconomic status. Numerous reports consistently demonstrate that CVDs are a major risk factor for severe course of coronavirus disease 2019 (COVID-19), including higher risks of hospitalizations and inpatient mortality. In the context of the current pandemic, managing patients with CVDs requires special attention from doctors. There are now more and more reports of the long-term effects of COVID-19. The long-term effects on cardiovascular system of millions of COVID-19 survivors are currently unknown. The aim of the review was to systematize the accumulated knowledge about the mutual influence of COVID-19 and CVDs. The features of CVD impact on the course and outcomes of COVID-19, as well as the reasons for the worsening of CVD course in patients with COVID-19 are considered. The impact of redistribution of health care resources and large-scale isolation measures on the management of patients with CVDs is discussed. The review also presents the most relevant data on long COVID. Predictors of a long-term disease course were identified for risk stratification in order to timely implement preventive measures and develop an individualized treatment. The authors focused on finding novel approaches to reduce CVD mortality during a pandemic.

Background: According to the WHO, the COVID-19 pandemic could have a negative impact on the mental health of individuals, such as an exacerbation of existing difficulties. Individuals with ADHD may be specifically challenged by the pandemic. Aims: To provide a systematic review of evidence regarding the COVID-19’s impact on mental health of individuals with ADHD during the COVID-19 lockdown. Methods: This registered review (PROSPERO ID CRD42021238770) adhered to Prisma guidelines. Systematic searches in electronic databases PubMed and PsycINFO were carried out. A total of 12 studies covering 3,028 subjects were included. Results: COVID-19 pandemic is associated with increased ADHD symptoms and psychological difficulties. Some studies reported that individuals experienced positive outcomes. The methodological quality of the studies was low to moderate. Conclusion: COVID-19 can affect the mental health of individuals with ADHD negatively, although methodological limitations should be considered. Further research should generate knowledge about long-term effects impact of the pandemic and about appropriate support.

Background Correct certification of causes of death by physicians according to International Classification of Diseases (ICD) rules is essential to generate mortality statistics of the quality needed to guide public health policy debates and reliably monitor the impact of health interventions. Several efforts to train doctors have been undertaken in the Philippines to improve Medical Certification of Causes of Death (MCCOD). However, there is very little evidence about the long-term effects of training interventions for medical certification. Objective To test whether there were measurable long-term impacts of this large-scale training intervention for improving medical certification and reducing different types of certification errors. Method We assessed the quality of 2100 MCCOD completed before face-to-face training with those written by the same doctors 6 months after the training. An assessment tool was used to evaluate the quality of MCCOD. Results Less than 1% of the 2100 MCCOD assessed prior to the training were completely error-free, increasing to 19.2% 6 months after the training. On average, the number of errors per certificate fell from 2.2 pre-training to 1.3, six months after training. Importantly, there was a 38% decrease in writing ill-defined causes on the last line, which is particularly important for the policy utility of data. Conclusion Training doctors in correct medical certification can have a long-term impact on medical certification practices. Implications Shorter, more focused, trainings that address the most common medical certification errors could have an even greater impact on medical certification practices.
