Pressure injury incidence and impact on patients treated with prone positioning for COVID-19 ARDS.

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.

Visiting and Communication Policy in Intensive Care Units during COVID-19 Pandemic: A Cross-sectional Survey from South Asia and the Middle East.

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.

C reactive protein elevation among children or among mothers' of children with autism during pregnancy, a review and meta-analysis.

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.

Impact of Dobutamine in Patients With Septic Shock: A Meta-Regression Analysis.

Septic shock frequently requires vasopressor agents. Conflicting evidence exists for use of inotropes in patients with septic shock. Data from English studies on human adult septic shock patients were collected. A total of 83 studies were reviewed, while 11 studies with 21 data sets including 239 patients were pooled for meta-regression analysis. For VO2, pooled difference in means (PDM) was 0.274. For cardiac index (CI), PDM was 0.783. For delivery of oxygen, PDM was -0.890. For heart rate, PDM was -0.714. For left ventricle stroke work index, PDM was 0.375. For mean arterial pressure, PDM was -0.204. For mean pulmonary artery pressure, PDM was 0.085. For O2 extraction, PDM was 0.647. For PaCO2, PDM was -0.053. For PaO2, PDM was 0.282. For pulmonary artery occlusive pressure, PDM was 0.270. For pulmonary capillary wedge pressure, PDM was 0.300. For PVO2, PDM was -0.492. For right atrial pressure, PDM was 0.246. For SaO2, PDM was 0.604. For stroke volume index, PDM was 0.446. For SvO2, PDM was -0.816. For systemic vascular resistance, PDM was -0.600. For systemic vascular resistance index, PDM was 0.319. Meta-regression analysis was performed for VO2, DO2, CI, and O2 extraction. Age was found to be significant confounding factor for CI, DO2, and O2 extraction. APACHE score was not found to be a significant confounding factor for any of the parameters. Dobutamine seems to have a positive effect on cardiovascular parameters in patients with septic shock. Prospective studies with larger samples are required to further validate this observation.

Effect of Positive Airway Pressure Therapy on Body Mass Index in Obese Patients With Obstructive Sleep Apnea Syndrome: A Prospective Study.

Because obesity is a common cause of obstructive sleep apnea syndrome (OSAS), weight loss can be an effective treatment. OSAS also may cause weight gain in some patients. Effective treatment of sleep apnea may facilitate weight loss in obese patients. We hypothesize that positive airway pressure (PAP) therapy is associated with weight loss in obese patients with OSAS. This was a single-center observational prospective cohort study. Forty-five patients were diagnosed with OSAS after polysomnographic analysis in sleep laboratory and underwent continuous positive airway pressure titration. Patients were followed for 3 months in terms of change in body mass index (BMI) and compliance with PAP therapy. Of the 45 patients recruited, 3 patients were eliminated because of miss recruitment. Nine patients had incomplete data, and the rest (n = 33) were included for analysis. The mean age was 54.9 ± 16.9 years (mean ± SD), 93.9% were male, and 90.9% were whites. Mean apnea-hypopnea index was 36.3 ± 28.17 events per hour. Mean BMI before treatment was 34.7 ± 3.9 kg/m. Fifteen patients (45.5%) were compliant with therapy of OSAS with PAP. There was no difference in age, gender, neck circumference, BMI, and apnea-hypopnea index of patients compliant to therapy when compared with those who were not. There was a significant decrease in BMI in patients compliant with PAP therapy compared with noncompliant patients (-1.2 ± 0.7 vs. 0.3 ± 0.9 kg/m, P ≤ 0.001). PAP therapy may cause significant loss of weight within 3 months in obese patients with OSAS. Further study is needed to elucidate the physiological basis of this change.

Role of Anemia in Home Oxygen Therapy in Chronic Obstructive Pulmonary Disease Patients.

Anemia is a known comorbidity found in chronic obstructive pulmonary disease (COPD) patients. Hypoxemia is common and basically due to ventilation/perfusion (V/Q) mismatch in COPD. Anemia, by decreasing arterial oxygen content, may be a contributing factor for decreased delivery of oxygen to tissues. The objective of this study is to determine if anemia is a factor in qualifying COPD patients for home oxygen therapy. The study was designed as a retrospective, cross-sectional, observational chart review. Patients who were referred for home oxygen therapy evaluation were selected from the computerized patient record system. Demographic data, oxygen saturation at rest and during exercise, pulmonary function test results, hemoglobin level, medications, reason for anemia, comorbid diseases, and smoking status were recorded. The χ tests, independent sample t tests, and logistic regression were used for statistical analysis. Only 356 of total 478 patient referrals had a diagnosis of COPD over a 2-year period. Although 39 of them were excluded, 317 patients were included in the study. The overall rate of anemia was 38% in all COPD patients. Anemia was found significantly more frequent in COPD patients on home oxygen therapy (46%) than those not on home oxygen therapy (18.5%) (P < 0.0001). Mean saturation of peripheral oxygen values were significantly lower in anemic COPD patients both at rest and during exercise (P < 0.0001). Also, in COPD patients, age, Global Initiative for Chronic Obstructive Lung Disease class, smoking status, hemoglobin level, hematocrit, percent of forced expiratory volume in first second, forced expiratory volume in first second/forced vital capacity, residual volume/total lung volume, percent of carbon monoxide diffusion capacity were significantly different between home oxygen therapy and those not on home oxygen therapy (P < 0.05). Multivariate logistic regression showed that anemia remained a strong predictor for long-term oxygen therapy use in COPD patients after adjusting for other significant parameters. Anemic COPD patients are more hypoxic especially during exercise than those who are not anemic. We conclude that anemia is a contributing factor in qualifying COPD patients for home oxygen therapy.

Potential Augmentation of the Risk of Ischemic Cerebrovascular Accident by Chronic Obstructive Pulmonary Disease in Patients with Atrial Fibrillation.

BACKGROUND: Atrial fibrillation (AF) is a potent risk factor for ischemic cerebrovascular accident (ICVA). Inflammation is a potential pathogenic factor for atherosclerosis and ICVA. Chronic obstructive pulmonary disease (COPD) is associated with increased inflammatory markers. Subjects who frequently experience COPD and AF together may have higher risk of ICVA. The objective of the study is to compare the prevalence of ICVA in patients with atrial fibrillation and COPD together versus atrial fibrillation alone. METHODS: Subjects diagnosed with COPD, AF, and ICVA were categorized into 3 groups: COPD, AF, and COPD plus AF. Prevalence of ICVA was compared. Confounding factors affecting ICVA risk were recorded: age, diabetes, hypertension, peripheral vascular disease, dyslipidemia, and congestive cardiac failure. RESULTS: Total charts reviewed were 500: COPD alone 244, AF alone 188, and both together 68. ICVA was documented in 132 (26.4%) subjects. Prevalence of ICVA was 11.8% (COPD alone), 29.8% (AF alone), and 39.7% (AF plus COPD). COPD plus AF group had ICVA 2.05 (95% confidence interval [CI], 1.203-3.94; P = .007) times compared with others. ICVA was also higher in patients with AF only versus COPD only (P < .001). Logistic regression showed AF plus COPD was a stronger predictor of ICVA (P = .001) than AF only (P = .07) or COPD only (P = .8). Odds ratio for ICVA was 2.85 (CI, 1.57-5.16; P = .001) for AF plus COPD versus 1.81 (CI, .94-3.47; P = .71) for AF only and 1.08 (CI, .58-2.10; P = .8) for COPD only. CONCLUSIONS: COPD may increase the risk of ischemic stroke in subjects with AF. Presence of COPD may increase the risk of ischemic stroke in subjects with AF.

The role of severity of obstructive sleep apnea measured by apnea-hypopnea index in predicting compliance with pressure therapy, a meta-analysis.

Obstructive sleep apnea (OSA) is associated with diabetes, hypertension, stroke, coronary artery disease, and premature death. Positive airway pressure (PAP) is the mainstay of therapy. Despite its effective treatment with PAP therapy, noncompliance remains high. Many factors determine compliance. The role of severity of OSA measured by the apnea-hypopnea index (AHI) remains controversial. Meta-analysis of studies examining this role of AHI was performed. A systematic review of the medical literature was conducted using PubMed and Cochrane library by utilizing different combinations of key words: sleep apnea, AHI, compliance, and nonadherence. Inclusion criteria were English articles; Studies with adult population; with 2 groups of patients (compliant and noncompliant); Studies utilizing objective definition of compliance (PAP usage of >4 hours per night for 70% of days or usage >5 d/wk and for >4 hours per night). Studies were analyzed by standard methods of meta-analysis. The studies were heterogeneous for AHI; therefore, the random effect model was used. Six hundred forty-one manuscripts were found. Of these, 230 were found to be appropriate for full text evaluation. Thirty-one met inclusion criteria. Twelve of these studies used objective criteria for PAP compliance and were hence included in meta-analysis. All the subjects had OSA determined by polysomnography, for whom PAP was employed. Compliance to PAP therapy was evaluated after a period of time ranging from 4 weeks to 8 years. There were 1438 subjects included in the meta-analysis; 886 subjects were PAP compliant, whereas 552 subjects were noncompliant. A greater AHI was found in PAP compliant patients. The mean difference between compliant and noncompliant groups was 5.9 (95% confidence interval: 0.19-11.67, P < 0.05). Patients with mild OSA are less likely to be compliant with PAP therapy. These patients should receive aggressive management particularly at the start of therapy with close follow-up to increase compliance.

Effect of musculoskeletal pain on sleep architecture in patients with obstructive sleep apnea.

RATIONALE: Obstructive sleep apnea and chronic musculoskeletal pain both affect sleep. Sleep architecture of patients suffering from both is largely unknown. OBJECTIVES: This study seeks to define the sleep architecture of patients with chronic musculoskeletal pain and obstructive sleep apnea. METHODS: Patients with obstructive sleep apnea diagnosed by sleep study during the past 3 years were included. Patients with clinical documentation of chronic musculoskeletal pain constituted cases, while others were classified as controls. MEASUREMENTS: Demographics, clinical factors affecting sleep, medications affecting sleep, Epworth sleepiness scores, and polysomnographic parameters; total sleep time, sleep efficiency, sleep stages, rapid eye movement (REM) sleep onset, apnea-hypopnea index, arousal index, and periodic leg movements were recorded. RESULTS: There were 393 subjects: 200 cases (obstructive sleep apnea and chronic musculoskeletal pain) and 193 controls (obstructive sleep apnea alone). There was significant difference in total sleep time (274.5 ± 62.5 vs. 302.2 ± 60.1 min, p = 0.0001), sleep efficiency (73.54 ± 15.8 vs. 78.76 ± 14.3%, p = 0.0003), and REM sleep onset (148.18 ± 80.5 vs. 124.8 ± 70.9 min, p = 0.006). Subgroup analysis within the obstructive sleep apnea with chronic musculoskeletal pain group revealed that subjects had better total sleep time and sleep efficiency if they were on REM sleep affecting medications (suppressants and stimulants). Those on REM sleep suppressants slept 25.7 min longer and had 6.4% more efficient sleep than those not on REM suppressants (p = 0.0034 and p = 0.0037). CONCLUSION: Patients with obstructive sleep apnea and chronic musculoskeletal pain sleep not only significantly less but also with inferior sleep quality. Their REM sleep is also less in duration and its onset is delayed. Despite low TST and SE, these patients may not exhibit sleepiness.

Effect of the full moon on mortality among patients admitted to the intensive care unit.

OBJECTIVE: To determine the lunar effect on mortality among patients admitted to the intensive care unit. METHODS: The retrospective study conducted at Rosalind Franklin University of Medicine and Science, North Chicago, and comprised data of 4387 patients in intensive care unit from December 2002 to November 2004. The subjects were divided into two groups: patients who died on full moon days (the 14th, 15th, and 16th days of the lunar month); and patients who died on the other days of the month. The mortality rates were calculated for patients in both groups. Parameters including patients' age, gender, acute physiology and chronic health evaluation scores, predicted mortality rates, type of intensive care unit, and actual mortality were compared, and non-parametric tests were performed to determine whether there were any differences between the groups. RESULTS: Of the 4387 patients who were followed for 23 months, 297 patients died, including 31 on full moon days and 266 patients on the other days of the month. Both groups were similar in terms of mean age (73.6 +/- 14.59 vs. 71.07 +/- 16.13 years; p = 0.599), acute physiology and chronic health evalutation scores (82.06 +/- 24.19 vs. 76.52 +/- 27.42; p = 0.258), and predicted mortality (0.405 +/- 0.249 vs. 0.370 +/- 0.268; p = 0.305). There was no difference in the frequency of death between the full moon days and the other days (10.33 +/- 0.58 vs. 9.8 +/- 3.46; p = 0.845). CONCLUSIONS: The full moon does not affect the mortality of the patients in intensive care unit.
