Objective: To determine the incidence of pressure injuries (PIs) and their impact on clinical outcomes in patients treated with prone positioning for COVID-19 acute respiratory distress syndrome (ARDS). Method: All patients with COVID-19 ARDS who were treated with prone positioning were categorised as cases and those who were not treated with prone positioning were categorised as controls. Demographics, clinical data and confounding variables affecting outcomes were recorded. Outcome variables of mortality and length of stay in intensive care units (ICUs) for both groups were recorded. Both groups' incidence of PIs were recorded and compared using statistical tests. Fisher's exact test was used for categorical variables, and Mann--Whitney U test was used for continuous variables. Results: The sample included 212 patients, treated with prone position (n=104) and without prone treatment (n=108). The incidence of PIs was n=75 (35.4%). PIs were significantly higher in patients in the prone position (n=51, 49%) compared with patients who were not (n=24, 22%); p=0.001. Patients in the prone position were found to have lower APACHE-2 scores, longer stays on the ventilator, ICU and in the hospital. Conclusion: PIs are more prevalent in patients in the prone position and it adversely impacts clinical outcomes; it prolongs the length of stay on the ventilator, in the ICU and in the hospital. Declaration of interest: The authors have no conflicts of interest to declare. [ABSTRACT FROM AUTHOR]

Background: The optimal timing of intubation has been debated among healthcare professionals, current studies do not show any differences between early and late intubation. most studies failed to show any significant difference in clinical outcomes between early or late intubation. Methods: The study was conducted as a retrospective review of subjects with confirmed coronavirus disease 2019 admitted to the Dubai Hospital intensive care unit (ICU). Study variables included time to intubation, duration of supplemental oxygen requirement>15L/min, and cumulative duration of tachypnea and tachycardia while on the aforementioned oxygen requirement on this oxygen usage level. Each time duration was assessed for correlation with clinical variables including mortality and length of stay in ICU and hospital. Results: Subjects who require endotracheal intubation within 4 h after the start of oxygen >15 L/min have lower survival (P = 0.03). Subjects who have tachypnea on the aforementioned oxygen requirement for 6–19.5 h (P = 0.01) before they require intubation have better survival. No duration of tachycardia has any significant effect on survival. Only the duration of invasive mechanical ventilation (MV) correlated with the hospital length of stay. Conclusions: Subjects who require endotracheal intubation within 4 h after the start of oxygen >15 L/min have lower survival. The optimal time for intubation is after tachypnea of 6 h but before 19.5 h. No duration of tachycardia has any significant effect on survival. Only the duration of invasive MV correlated with the hospital length of stay. [ABSTRACT FROM AUTHOR]

Purpose: The coronavirus disease-2019 (COVID-19) pandemic had affected the visiting or communicating policies for family members. We surveyed the intensive care units (ICUs) in South Asia and the Middle East to assess the impact of the COVID-19 pandemic on visiting and communication policies. Materials and method: A web-based cross-sectional survey was used to collect data between March 22, 2021, and April 7, 2021, from healthcare professionals (HCP) working in COVID and non-COVID ICUs (one response per ICU). The topics of the questionnaire included current and pre-pandemic policies on visiting, communication, informed consent, and end-of-life care in ICUs. Results: A total of 292 ICUs (73% of COVID ICUs) from 18 countries were included in the final analysis. Most (92%) of ICUs restricted their visiting hours, and nearly one-third (32.3%) followed a "no-visitor" policy. There was a significant change in the daily visiting duration in COVID ICUs compared to the pre-pandemic times (p = 0.011). There was also a significant change (p <0.001) in the process of informed consent and end-of-life discussions during the ongoing pandemic compared to pre-pandemic times. Conclusion: Visiting and communication policies of the ICUs had significantly changed during the COVID-19 pandemic. Future studies are needed to understand the sociopsychological and medicolegal implications of revised policies. [ABSTRACT FROM AUTHOR]

Objective: To evaluate if children with ASD, or mothers of ASD children have elevated CRP during pregnancy. Background: Autism spectrum disorder (ASD) is a neuro developmental disorder with incidence of 1 in 68 children occur in all racial, ethnic, and socioeconomic groups. Economic burden between $11.5 billion - $60.9 billion and family average medical expenditures of $4110–$6200 per year. Conflicting evidence exist about role of maternal CRP during pregnancy with ASD child. Methods: Searches on database; Pubmed, Medline, Embase and google scholar using key words; C reactive protein (CRP), Maternal CRP, ASD, autism, autistic disorder, Inflammation. All English-language studies published between 1960 and 2019 pertaining to CRP and ASD. All Studies which provided data on CRP levels during pregnancy (mCRP) of Mothers of offsprings with ASD and (mCRP) of mothers of normal subjects were selected. Data were extracted in the form of odd ratios of having high mCRP in mothers of children with ASD versus mCRP of mothers of normal controls. Since these odd ratios were adjusted, therefore no Meta regression were attempted. Significant heterogeneity was found; therefore, random effect model was employed. Results: Review of CRP levels in children with ASD showed higher level in children with ASD than control, although different methodology and absence of numerical data did not allow metanalysis. Regarding mCRP and ASD, three studies were identified that provide data on mCRP and ASD. Four datasets were created from these 3 studies as the study by Zerbo et al. provided data in 2 subsets. Total number of subjects were 5258 (Brown, N = 677, Zerbo = 416, Koks = 4165) extracted data from these studies was pooled for analysis. Random effect model was employed and substantial heterogeneity among the studies was observed 11. Mothers of children with ASD have adjusted Odd ratio of 1.02 (0.948 to 1.103, I2 = 75, P = 0.558) to have high mCRP comparing mothers of control. Conclusion: Mothers of children with ASD appear not to have elevated CRP during pregnancy. Children with ASD appear to have higher levels of CRP levels. [ABSTRACT FROM AUTHOR]

Background: Obstructive sleep apnea (OSA) is associated with coronary artery disease (CAD). Intermittent hypoxia associated with OSA increases sympathetic activity and may cause systemic inflammation, which may contribute to CAD in patients with OSA. Treatment with continuous positive airway pressure (CPAP) has been shown to change levels of inflammatory markers. We analyzed data from published studies by a systematic meta-analysis. Objective: To asses if treatment for sleep apnea by CPAP will affect levels of inflammatory markers. Data resources: PubMed, Embase and Cochrane library. Methods: Study eligibility criteria full text English studies of adult, human subjects, addressing values of at least one of the inflammatory markers before and after CPAP treatment. We used the definition of OSA as an apnea-hypopnea index (AHI) of ≥5/h, reported values in mean and standard deviation or median with range. Participants: Adult, human. Interventions: CPAP treatment for OSA. Study appraisal and synthesis method: A total of 3835 studies were reviewed for inclusion, while 23 studies pooled for analysis. A total of 14 studies with 771 patients were pooled for C-reactive protein (CRP); 9 studies with 209 patients were pooled for tumor necrosis factor-alpha (TNF-α); and 8 studies with 165 patients were pooled for interleukin-6 (IL-6). Endpoint definitions: The following inflammatory markers were chosen: CRP, TNF-α, and IL - 6 . Results: C-reactive protein: Study level means ranged from 0.18 to 0.85 mg/dl before CPAP treatment and 0.10 to 0.72 mg/dl after CPAP treatment. Mean differences, at a study level, ranged from -0.05 to 0.50. The pooled mean difference was 0.14 [95% confidence interval 0.08 to 0.20, p < 0.00001]. There was heterogeneity in this endpoint (df = 13, p < 0.00001, I² = 95% ). Tumor necrosis factor-α: Study level means ranged from 1.40 to 50.24 pg/ml before CPAP treatment and 1.80 to 28.63 pg/ml after CPAP treatment. Mean differences, at a study level, ranged from -1.23 to 21.61. The pooled mean difference was 1.14 [95% confidence interval 0.12 to 2.15, p = 0.03]. There was heterogeneity in this endpoint (df = 8, p < 0.00001, I2 = 89%). Interleukin-6: Study level means ranged from 1.2 to 131.66 pg/ml before CPAP treatment and 0.45 to 66.04 pg/ml after CPAP treatment. Mean differences, at a study level, ranged from -0.40 to 65.62. The pooled mean difference was 1.01 [95% confidence interval -0.00 to 2.03, p = 0.05]. There was heterogeneity in this endpoint (df = 7, p < 0.00001, I² =9 5 % ) . Limitations: Only published data. Studies pooled were mainly small, non-randomized trials. Conclusion: Sleep apnea treatment with CPAP improves levels of inflammatory markers. [ABSTRACT FROM AUTHOR]

Background. Obstructive sleep apnea (OSA) is associated with coronary artery disease. Intermittent hypoxia associated with OSA increases sympathetic activity and may cause systemic inflammation, which may contribute to atherosclerosis leading to an increase in the size of carotid intima media thickness (CIMT). Methods. PubMed and Cochrane library were reviewed by utilizing different combinations of key words: sleep apnea, carotid disease, intimamedia thickness, and carotid atherosclerosis. Inclusion criteria were English articles; studies with adult population with OSA and without OSA; CIMT recorded by ultrasound in mean and standard deviation or median with 95% confidence interval; and OSA defined as apnea hypopnea index of ⩾5/h. A total of 95 studies were reviewed for inclusion, with 16 studies being pooled for analysis. Results. Ninety-five studies were reviewed, while 16 studies were pooled for analysis; since some studies have more than one data set, there were 25 data sets with 1415 patients being pooled for meta-analysis. All studies used ultrasound to measure CIMT. CIMT standardized difference in means ranged from -0.883 to 8.01. The pooled standardized difference in means was 1.40 (lower limit 0.996 to upper limit 1.803, (P < 0.0001). Conclusion. Patients with OSA appear to have increased CIMT suggestive of an atherosclerotic process. [ABSTRACT FROM AUTHOR]
