Effect of tracheostomy timing on outcomes in patients with traumatic brain injury.

Tracheostomy following severe traumatic brain injury (TBI) is common, yet the outcomes associated with tracheostomy timing are unclear. The objective of this study was to assess hospital outcomes of tracheostomy timing in TBI patients. We retrospectively analyzed data from the National Inpatient Sample database of adult patients aged ≥18 years with a primary diagnosis of TBI. Indexed hospitalizations of TBI patients who underwent either percutaneous or surgical tracheostomy between 1995 and 2015 in the United States were included. The interventional groups were 1) early tracheostomy (≤7 days) vs standard tracheostomy (8-14 days), vs late tracheostomy (≥15 days), and 2) tracheostomy vs no tracheostomy. Propensity score matching and conditional logistic regression models were used to analyze in-hospital mortality, length of hospitalization, and in-hospital complications among TBI patients in relation to tracheostomy timing. The risk of in-hospital mortality was 35% lower in patients who underwent tracheostomy vs those who did not (odds ratio 0.65; P < 0.001). Patients who underwent early tracheostomy had a higher risk of in-hospital mortality compared to standard tracheostomy (odds ratio 1.69; P < 0.001) or late tracheostomy (odds ratio 1.80; P < 0.001). An early tracheostomy was associated with a shorter mean hospital length of stay (27 days) compared to standard (36 days) or late tracheostomy (48 days).

Transfusion Guidelines in Brain Tumor Surgery: A Systematic Review and Critical Summary of Currently Available Evidence.

OBJECTIVE: Red blood cell (RBC) transfusion is commonly indicated in brain tumor surgery due to risk of blood loss. Current transfusion guidelines are based on evidence derived from critically ill patients and may not be optimal for brain tumor surgeries. Our study is the first to synthesize available evidence to suggest RBC transfusion thresholds in brain tumor patients undergoing surgery. METHODS: A systematic review was conducted using PubMed, EMBASE, and Google Scholar databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to critically assess RBC transfusion thresholds in adult patients with brain tumors and complications secondary to transfusion following blood loss in the operating room or perioperative period. RESULTS: Seven articles meeting our search criteria were reviewed. Brain tumor patients who received blood transfusions were older, had greater rates of American Society of Anesthesiologists class 3 or 4, and presented with increased number of comorbidities including diabetes, hypertension, and cardiovascular diseases. In addition, transfused patients had a prolonged surgical time. Transfusions were associated with multiple postoperative major and minor complications, including longer hospital length of stay, increased return to the operating room, and elevated 30-day mortality. Analysis of transfusion thresholds showed that a restrictive hemoglobin threshold of 8 g/dL is safe in patients, as evidenced by a reduction in length of stay, mortality, and complications (level C class IIa). CONCLUSIONS: A restrictive Hb threshold of 8 g/dL appears to be safe and minimizes potential complications of transfusion in brain tumor patients.

Racial/Ethnic Disparity in Suicidal Ideation, Suicide Attempt and Non-suicidal Intentional Self-harm Among Pregnant Women in the United States.

We examined the prevalence of suicidal ideation, suicide attempt and non-suicidal intentional self-harm among pregnant women in the United States stratified by race/ethnicity. Data on hospital admissions among pregnant women 15-49 years during 2016-2017 compiled in the Nationwide Inpatient Sample were used for this study. We assessed the prevalence and factors of suicidal ideation, suicide attempt and non-suicidal intentional self-harm among different race/ethnicities. The prevalence of suicidal ideation, suicide attempt and non-suicidal intentional self-harm was greatest among hospitalized Non-Hispanic (NH) Black pregnant women. As compared to pregnant women who were routinely discharged, those who died during the course of hospitalization had about eight times the odds for NH-Whites, four times the odds for NH-Blacks and five times the odds for Hispanics of suicidal ideation or attempt. Appropriate measures are needed for prompt diagnosis and management of mental health issues in pregnant women belonging to vulnerable sub-groups.

Postoperative Transfusion Guidelines in Aneurysmal Cerebral Subarachnoid Hemorrhage: A Systematic Review and Critical Summary of Available Evidence.

OBJECTIVE: Surgical management of aneurysmal subarachnoid hemorrhage (SAH) often involves red blood cell (RBC) transfusion, which increases the risk of postoperative complications. RBC transfusion guidelines report on chronically critically ill patients and may not apply to patients with SAH. Our study aims to synthesize the evidence to recommend RBC transfusion thresholds among adult patients with SAH undergoing surgery. METHODS: A systematic review was conducted using PubMed, Google Scholar, and Web of Science electronic databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to critically assess primary articles discussing RBC transfusion thresholds and describe complications secondary to RBC transfusion in adult patients with SAH in the perioperative period. RESULTS: Sixteen articles meeting our search strategy were reviewed. Patients with SAH who received blood transfusion were older, female, had World Federation of Neurosurgical Societies grade IV-V and modified Fisher grade 3-4 scores, and presented with more comorbidities such as hypertension, diabetes, and cardiovascular and pulmonary diseases. In addition, transfusion was associated with multiple postoperative complications, including higher rates of vasospasms, surgical site infections, cardiovascular and respiratory complications, increased postoperative length of stay, and 30-day mortality. Analysis of transfused patients showed that a higher hemoglobin (>10 g/dL) goal after SAH was safe and that patients may benefit from a higher whole hospital stay hemoglobin nadir, as shown by a reduction in risk of cerebral vasospasm and improvement in clinical outcomes (level B class II). CONCLUSIONS: Among patients with SAH, the benefits of reducing cerebral ischemia and anemia are shown to outweigh the risks of transfusion-related complications.

Transfusion Guidelines in Traumatic Brain Injury: A Systematic Review and Meta-Analysis of the Currently Available Evidence.

Our study aims to provide a synthesis of the best available evidence on the hemoglobin (hgb) red blood cell (RBC) transfusion thresholds in adult traumatic brain injury (TBI) patients, as well as describing the risk factors and outcomes associated with RBC transfusion in this population. A systematic review and meta-analysis was conducted using PubMed, Google Scholar, and Web of Science electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to assess articles discussing RBC transfusion thresholds and describe complications secondary to transfusion in adult TBI patients in the perioperative period. Fifteen articles met search criteria and were reviewed for analysis. Compared to non-transfused, TBI patients who received transfusion tended to be primarily male patients with worse Injury Severity Score (ISS) and Glasgow Coma Scale. Further, the meta-analysis corroborated that transfused TBI patients are older (p = 0.04), have worse ISS scores (p = 0.001), receive more units of RBCs (p = 0.02), and have both higher mortality (p < 0.001) and complication rates (p < 0.0001). There were no differences identified in rates of hypertension, diabetes mellitus, and Abbreviated Injury Scale scores. Additionally, whereas many studies support restrictive (hgb <7 g/dL) transfusion thresholds over liberal (hgb <10 g/dL), our meta-analysis revealed no significant difference in mortality between those thresholds (p = 0.79). Current Class B/C level III evidence predominantly recommends against a liberal transfusion threshold of 10 g/dL for TBI patients (Class B/C level III), but our meta-analysis found no difference in survival between groups. There is evidence suggesting that an intermediate threshold between 7 and 9 g/dL, reflecting the physiological oxygen needs of cerebral tissue, may be worth exploring.

Clinical Outcomes of Noninvasive Ventilation in Asthma, Bronchiectasis, and Other COPD.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality and disability worldwide. Use of noninvasive ventilation (NIV) appears to be associated with a significant decrease in frequency of exacerbation, hospital admissions, and mortality in patients with COPD. In this study, we sought to determine clinical outcomes, prevalence, patient profiles and systems characteristics associated with the use of NIV in patients with asthma, bronchiectasis, and other COPD. METHODS: In this retrospective study, the Nationwide Inpatient Sample dataset was used to evaluate patient characteristics for adult hospitalizations for asthma, bronchiectasis, and other COPD between January 2002 and December 2017. Using the adjusted survey logistic regression model, the association between NIV and in-hospital mortality for asthma, bronchiectasis, and other COPD was ascertained. RESULTS: Other COPD hospitalization prevalence was nearly two times higher among non-Hispanic Black patients compared with non-Hispanic White patients (8.32/1000 vs 4.46/1000). There was a 4.3% average annual decrease in the rates of NIV among hospitalized patients with other COPD during the study period. Furthermore, nonusage of NIV was associated with increased in-hospital mortality for asthma (odds ratio [OR] 1.53, 95% confidence interval [CI] 1.50-1.57), bronchiectasis (OR 2.01, 95% CI 1.69-2.41), and other COPD (OR 1.24, 95% CI 1.16-1.32), respectively. CONCLUSIONS: Inpatient use of NIV has a clear mortality benefit in asthma, bronchiectasis, and COPD. These findings support a signal for potential benefit, particularly among certain populations and warrant further investigation.

A Framework for Protecting Pregnant Women in the Era of COVID-19 Pandemic.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for the coronavirus disease 2019 (COVID-19) pandemic, highlighted and compounded problems while posing new challenges for the pregnant population. Although individual organizations have provided disparate information, guidance, and updates on managing the pregnant population during the current COVID-19 pandemic, it is important to develop a collective model that highlights all the best practices needed to protect the pregnant population during the pandemic. To establish a standard for ensuring safety during the pandemic, we present a framework that describes best practices for the management of the pregnant population during the ongoing COVID-19 pandemic.

Trends and Racial/Ethnic Disparities in the Rates of Pre-eclampsia by HIV Status in the US.

BACKGROUND: Preeclampsia and HIV account for a significant proportion of the global burden of disease and pose severe maternal-fetal risks. There is a dearth of literature regarding racial/ethnic disparities in preeclampsia associated with HIV/AIDS in the US. METHODS: We retrospectively analyzed data from the National Inpatient Sample (NIS) database from 2002 to 2015 on a cohort of hospitalized pregnant women with or without preeclampsia and HIV. Joinpoint regression models were used to identify trends in the rates of preeclampsia among pregnant women living with or without HIV, stratified by race/ethnicity over the study period. We also assessed the association between preeclampsia and various socio-demographic factors. RESULTS: We analyzed over 60 million pregnancy-related hospitalizations, of which 3665 had diagnoses of preeclampsia and HIV, corresponding to a rate of 0.61 per 10,000. There was an increasing trend in the diagnosis of preeclampsia among hospitalized, pregnant women without HIV across each racial/ethnic category. The highest prevalence of preeclampsia was among non-Hispanic (NH) Blacks, regardless of HIV status. CONCLUSION: The increase in rates of pre-eclampsia between 2002 and 2015 was mostly noted among pregnant women without HIV. Regardless of HIV status, NH-Blacks experienced the highest discharge prevalence of preeclampsia.

Trends in Premature Deaths among Women Living with HIV/AIDS and Cervical Cancer.

OBJECTIVES: There is a lack of updated information on premature death and years of potential life lost (YPLL) among human immunodeficiency (HIV)-positive women with cervical cancer. We hypothesize that increased access to preventive resources such as antiretroviral therapy, preexposure prophylaxis, and human papillomavirus vaccines has reduced premature mortality and YPLL in these women in the previous decades. METHODS: We used data from the National Inpatient Sample database from 2003 to the third quarter of 2015, and restricted the analysis to HIV-positive women with or without cervical cancer. Joinpoint regression models were run to identify trends in the rates of HIV and cervical cancer. Overall and age-stratified YPLL were calculated for HIV-positive women with cervical cancer. Adjusted survey logistic regression models were built to determine the predictive factors of in-hospital mortality among women living with HIV. RESULTS: Among hospitalized women, low-income, non-Hispanic Blacks, and patients aged 40 to 59 years experienced greater frequencies of HIV/cervical cancer comorbidity. The prevalence of HIV hospitalizations increased by an average annual percentage of 0.9% (95% confidence interval 0.3-1.6). YPLL decreased in HIV-positive women living with and without cervical cancer by 4.9% and 4.3%, respectively. The trajectory for YPLL was not uniform across age groups. YPLL decreased substantially in women aged 20 to 29 years with HIV/cervical cancer comorbidity. Cervical cancer remained a significant predictor of mortality among HIV-positive women when adjusted for age, race, and insurance coverage. CONCLUSIONS: Within a large, national sample from 2003 to 2015, we found an overall declining trend in YPLL in women living with HIV/cervical cancer comorbidity. In-hospital mortality among HIV-positive women was associated with cervical cancer, age, race, and insurance coverage. We recommend further investigation into the quality of HIV and cervical cancer treatment and prevention services for the sociodemographic groups described.

Role of Social Determinants of Health in Widening Maternal and Child Health Disparities in the Era of Covid-19 Pandemic.

We present a conceptual model that describes the social determinants of health (SDOH) pathways contributing to worse outcomes in minority maternal and child health (MCH) populations due to the current COVID-19 pandemic. We used International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10) codes in the categories Z55-Z65 to identify SDOH that potentially modulate MCH disparities. These SDOH pathways, coupled with pre-existing comorbidities, exert higher-than-expected burden of maternal-fetal morbidity and mortality in minority communities. There is an urgent need for an increased infusion of resources to mitigate the effects of these SDOH and avert permanent truncation in quality and quantity of life among minorities following the COVID-19 pandemic.

A Surveillance System for the Maternal and Child Health (MCH) Population During the COVID-19 Pandemic.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent for coronavirus disease 2019 (COVID-19), and its ensuing mitigation measures have negatively affected the Maternal and Child Health (MCH) population. There is currently no surveillance system established to enhance our understanding of SARS-CoV-2 transmission to guide policy decision making to protect the MCH population in this pandemic. Based on reports of community and household spread of this novel infection, we present an approach to a robust family-centered surveillance system for the MCH population. The surveillance system encapsulates data at the individual and community levels to inform stakeholders, policy makers, health officials and the general public about SARS-CoV-2 transmission dynamics within the MCH population.

Temporal trends of gestational malaria in the United States.

BACKGROUND: Although regarded as rare in the United States (US), increased global traffic and importation of malaria from endemic countries may lead to a rise in gestational malaria in the US. METHODS: This multi-year retrospective study analyzed trends in diagnosed cases of gestational malaria from 2002 to 2017 using joinpoint regression models. We also assessed the association between gestational malaria and selected maternal-fetal adverse outcomes. RESULTS: Mothers diagnosed with gestational malaria tended to be older, and the majority of diagnosed cases (52.9%) were among Non-Hispanic (NH) Blacks. Diagnosed cases of gestational malaria are on the rise in the US. Mothers diagnosed with gestational malaria were 5 times as likely (OR = 5.05, 95% CI: 4.05-6.29) to be anemic as compared to those without malaria. Compared to NH-Whites, NH-Black mothers were twice as likely to experience stillbirth, had nearly 50% greater adjusted odds of severe preeclampsia, and had about 30% elevated likelihood for preterm labor. CONCLUSIONS: There is a need to dedicate appropriate resources to identify women that are at risk for gestational malaria in order to prevent related pregnancy complications.
