简介：AbstractNeurocritical care (NCC) is not only generally guided by principles of general intensive care, but also directed by specific goals and methods. This review summarizes the common pulmonary diseases and pathophysiology affecting NCC patients and the progress made in strategies of respiratory support in NCC. This review highlights the possible interactions and pathways that have been revealed between neurological injuries and respiratory diseases, including the catecholamine pathway, systemic inflammatory reactions, adrenergic hypersensitivity, and dopaminergic signaling. Pulmonary complications of neurocritical patients include pneumonia, neurological pulmonary edema, and respiratory distress. Specific aspects of respiratory management include prioritizing the protection of the brain, and the goal of respiratory management is to avoid inappropriate blood gas composition levels and intracranial hypertension. Compared with the traditional mode of protective mechanical ventilation with low tidal volume (Vt), high positive end-expiratory pressure (PEEP), and recruitment maneuvers, low PEEP might yield a potential benefit in closing and protecting the lung tissue. Multimodal neuromonitoring can ensure the safety of respiratory maneuvers in clinical and scientific practice. Future studies are required to develop guidelines for respiratory management in NCC.

简介：AbstractBackground:Feeding intolerance (FI) among intensive care unit (ICU) patients undergoing early continuous enteral nutrition (EN) is related to poor outcomes. This study aimed to explore the prevalence and risk factors of FI in ICU patients.Methods:We retrospectively enrolled 1057 patients who received early continuous EN via a nasogastric tube between January 2014 and August 2019. The prevalence of FI during the first 7 days of ICU stay was calculated, and the risk factors were investigated using multivariate logistic regression analysis.Results:The prevalence of FI during the first 7 days of ICU stay was 10.95%. FI occurred in 159 of 1057 (15.04%) patients on ICU day 2, 114 of 977 (11.67%) patients on ICU day 3, and 86 of 715 (12.03%) patients on ICU day 7. Mechanical ventilation (MV) (odds ratio [OR]: 1.928, 95% confidence interval [CI]: 1.064–3.493, P = 0.03) was an independent risk factor for FI defined by a gastric residual volume (GRV) of 200 mL and/or vomiting, and acute renal failure (OR: 3.445, 95% CI: 1.115–10.707, P = 0.032) was an independent risk factor of FI defined by a GRV of 500 mL and/or vomiting. Continuous renal replacement therapy (CRRT) was an independent predictor regardless of the FI defined by a GRV of 200 mL (OR: 2.064, 95% CI: 1.233–3.456, P = 0.006) or 500 mL (OR: 6.199, 95% CI: 2.108–18.228, P = 0.001) in the ICU patients.Conclusions:FI occurs frequently in early ICU days, especially in patients receiving MV and CRRT. However, further investigation of a consensus definition of FI and risk factors is still warranted in future studies.

简介：AbstractImportance:During the coronavirus disease 2019 (COVID-19) lockdown, changes in the visiting rules in neonatal units might have affected the initiation and continuation of breastfeeding.Objective:To investigate the effects of the implementation of the COVID-19 lockdown in the UK on mother’s own milk (MOM) feeding in hospital and at the time of discharge in two UK neonatal units.Methods:Retrospective cohort study using routinely recorded data from electronic patient records. Data were retrieved from two neonatal services in the UK East Midlands region. Adjusted logistic regression was used to compare the odds of MOM feeding before, and after the implementation of the UK lockdown.Results:Among 2073 infants, after adjusting for maternal and infant characteristics and underlying trends over time, there were no differences in the odds of infants receiving any MOM during admission; any MOM at discharge or exclusive MOM at discharge before and after the imposition of the lockdown. Infants with birthweight <1000 g were three times less likely to receive any MOM at discharge compared to those with birthweight >2500 g (adjusted odds ratio [OR] 0.33, 95% confidence interval [CI]: 0.22–0.50). Younger mothers were less likely, and Black British mothers more likely, to be feeding MOM to their infants at discharge, while women in the least deprived Index of Multiple Deprivation (IMD) quintiles were 2–4 times more likely to do so, compared to those in the most deprived IMD quintile (adjusted OR 2.78, 95% CI: 1.97–3.90).Interpretation:Despite the difficulties faced during COVID-19 pandemic-induced restrictions, infants in the participating neonatal units continued to receive MOM in similar proportions as before the pandemic.

简介：AbstractObjective:To examine referral pattern, the timing of diagnostic/staging processes, and treatment initiation for new head and neck cancer patients in a community setting.Methods:Patients with a newly diagnosed previously untreated diagnosis of head neck cancer managed at Asplundh Cancer Pavilion/Abington Memorial Hospital from October 2018 to March 2020. Source of referral and preceding workup were examined as well as intervals between initial head and neck consult and various timepoints of treatment initiation.Results:One hundred and five patients were included in the study. The primary referral sources were external general otolaryngology (56.3%). Oral surgery and dermatology obtained tissue biopsy approximately 80% of the time before referral. The average time from the ordering of initial staging positron emission tomography/computed tomography to finalized results was 14 days (range: 10-25 days). Patients referred from dermatology and oral surgery were more likely to require single modality care, namely definitive surgical management. Time to treatment initiation average was 37 days (range: 29-41 days). Patients with longer treatment times noted significantly higher times to both radiation and medical oncology consults (48.42 vs. 18.13 days; P < 0.001).Conclusions:No notable differences in treatment initiation times were identified based on referral source or extent of workup performed before head/neck surgery consult. It appears the largest opportunities for improvement in terms of reducing overall treatment length exist in the optimization of radiation initiation time.

简介：AbstractBackground:Lymphatic filariasis (LF) remains one of the world’s most debilitating parasitic infections and is a major contributor to poor health in many endemic countries. The provision of continuing care for all those affected by LF and its consequences is an important component of the United Nations’ Sustainable Development Goals. The aim of this study is to integrate lymphedema care into the primary health care system of the State by developing lymphedema clinics at each district, through training of health personnel to fulfill WHO recommendation for morbidity management and disability prevention.Methods:Selected health care providers from all the districts in Kerala State of India participated in intensive training sessions endorsed by the State’s health administration. The six training sessions (from 5 June 2017 to 25 May 2018) included appropriate self-care information and development of individual plans for each participating institution to provide instruction and care for their lymphoedema patients. The learning achieved by attendees was assessed by pre- and post-training tests. The number of lymphoedema patients receiving care and instruction from the post-training activities of each participating institution was assessed from local records, 6 months after the conclusion of the training sessions.Results:One hundred and eighty-four medical personnel (91 doctors and 93 nurses) from 82 medical institutions were trained which quickly led to the establishment of active lymphoedema clinics providing the essential package of care (EPC) for lymphoedema patients at all the participating institutions. Six months after the training sessions the number of previously unidentified lymphoedema patients registered and receiving care at these clinics ranged from 296 to almost 400 per clinic, with a total of 3,477 new patients receiving training in EPC.Conclusions:Generalist health personnel, when appropriately trained, can provide quality lymphoedema care in public health settings and patients when provided services close to their home, are willing to access them. This is a feasible strategy for integrating long term care for LF patients into the national health system, and is a clear example of moving towards equity in health care for the medically underserved, and thus successfully addresses a major goal of the global program to eliminate lymphatic filariasis.

简介：AbstractBackground:It is crucial to improve the quality of care provided to ICU patient, therefore a national survey of the medical quality of intensive care units (ICUs) was conducted to analyze adherence to quality metrics and outcomes among critically ill patients in China from 2015 to 2019.Methods:This was an ICU-level study based on a 15-indicator online survey conducted in China. Considering that ICU care quality may vary between secondary and tertiary hospitals, direct standardization was adopted to compare the rates of ICU quality indicators among provinces/regions. Multivariate analysis was performed to identify potential factors for in-hospital mortality and factors related to ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CRBSIs), and catheter-associated urinary tract infections (CAUTIs).Results:From the survey, the proportions of structural indicators were 1.83% for the number of ICU inpatients relative to the total number of inpatients, 1.44% for ICU bed occupancy relative to the total inpatient bed occupancy, and 51.08% for inpatients with Acute Physiology and Chronic Health Evaluation II scores ≥15. The proportions of procedural indicators were 74.37% and 76.60% for 3-hour and 6-hour surviving sepsis campaign bundle compliance, respectively, 62.93% for microbiology detection, 58.24% for deep vein thrombosis prophylaxis, 1.49% for unplanned endotracheal extubations, 1.99% for extubated inpatients reintubated within 48 hours, 6.38% for unplanned transfer to the ICU, and 1.20% for 48-hour ICU readmission. The proportions of outcome indicators were 1.28‰ for VAP, 3.06‰ for CRBSI, 3.65‰ for CAUTI, and 10.19% for in-hospital mortality. Although the indicators varied greatly across provinces and regions, the treatment level of ICUs in China has been stable and improved based on various quality control indicators in the past 5 years. The overall mortality rate has dropped from 10.19% to approximately 8%.Conclusions:The quality indicators of medical care in China’s ICUs are heterogeneous, which is reflected in geographic disparities and grades of hospitals. This study is of great significance for improving the homogeneity of ICUs in China.

简介：AbstractBackground:Ciprofol (HSK3486; Haisco Pharmaceutical Group Co., Ltd., Chengdu, China), developed as a novel 2,6-disubstituted phenol derivative showed similar tolerability and efficacy characteristics as propofol when applicated as continuous intravenous infusion for 12 h maintenance sedation in a previous phase 1 trial. The phase 2 trial was designed to investigate the safety, efficacy, and pharmacokinetic characteristics of ciprofol for sedation of patients undergoing mechanical ventilation.Methods:In this multicenter, open label, randomized, propofol positive-controlled, phase 2 trial, 39 Chinese intensive care unit patients receiving mechanical ventilation were enrolled and randomly assigned to a ciprofol or propofol group in a 2:1 ratio. The ciprofol infusion was started with a loading infusion of 0.1-0.2 mg/kg for 0.5-5.0 min, followed by an initial maintenance infusion rate of 0.30 mg·kg-1·h-1, which could be adjusted to an infusion rate of 0.06 to 0.80 mg·kg-1·h-1, whereas for propofol the loading infusion dose was 0.5-1.0 mg/kg for 0.5-5.0 min, followed by an initial maintenance infusion rate of 1.50 mg·kg-1·h-1, which could be adjusted to 0.30-4.00 mg·kg-1·h-1 to achieve -2 to +1 Richmond Agitation-Sedation Scale sedation within 6-24 h of drug administration.Results:Of the 39 enrolled patients, 36 completed the trial. The median (min, max) of the average time to sedation compliance values for ciprofol and propofol were 60.0 (52.6, 60.0) min and 60.0 (55.2, 60.0) min, with median difference of 0.00 (95% confidence interval: 0.00, 0.00). In total, 29 (74.4%) patients comprising 18 (69.2%) in the ciprofol and 11 (84.6%) in the propofol group experienced 86 treatment emergent adverse events (TEAEs), the majority being of severity grade 1 or 2. Drug- and sedation-related TEAEs were hypotension (7.7% vs. 23.1%, P = 0.310) and sinus bradycardia (3.8% vs. 7.7%, P = 1.000) in the ciprofol and propofol groups, respectively. The plasma concentration-time curves for ciprofol and propofol were similar.Conclusions:ciprofol is comparable to propofol with good tolerance and efficacy for sedation of Chinese intensive care unit patients undergoing mechanical ventilation in the present study setting.Trial registration:ClinicalTrials.gov, NCT04147416.
