Financial Hardship and Sleep Quality Among Black American Women With and Without Systemic Lupus Erythematosus.

OBJECTIVE: To compare dimensions of financial hardship and self-reported sleep quality among Black women with versus without systemic lupus erythematosus (SLE). METHODS: Participants were 402 Black women (50% with validated diagnosis of SLE) living in Georgia between 2017 and 2020. Black women with SLE were recruited from a population-based cohort established in Atlanta, and Black women without SLE were recruited to be of comparable age and from the same geographic areas as SLE women. Financial hardship was measured using three different scales: financial adjustments, financial setbacks, and financial strain. Sleep was assessed continuously using the Pittsburgh Sleep Quality Index (PSQI) scale. Each dimension of financial hardship was analyzed separately in SLE-stratified multivariable linear regression models and adjusted by sociodemographic and health status factors. RESULTS: Dimensions of financial hardship were similarly distributed across the two groups. Sleep quality was worse in Black women with, versus without, SLE (p < .001). Among Black women with SLE, financial adjustment was positively associated with a 0.40-unit increase in poor sleep quality (95% CI = 0.12-0.67, p = .005). When accounting for cognitive depressive symptoms, financial setbacks and strain were somewhat attenuated for Black women with SLE. Overall, no associations between financial hardships and sleep quality were observed for the women without SLE. CONCLUSIONS: Black women with SLE who experience financial hardships may be more at risk for poor sleep quality than Black women without SLE. Economic interventions targeting this population may help improve their overall health and quality of life.

Effects of pair housing on behavior, cortisol, and clinical outcomes during quarantine-like procedures for rhesus macaques (Macaca mulatta).

BACKGROUND: Compatible pair housing of macaques in research settings increases species-typical behaviors and facilitates beneficial social buffering. It is not yet established whether these benefits are maintained after intrafacility transfer and domestic quarantine, which are two stressors that can lead to behavioral and clinical abnormalities. METHODS: We evaluated 40 adolescent male rhesus macaques who were single- or pair-housed immediately following an intrafacility transfer. We measured behavior, fecal cortisol, body weight, and diarrhea occurrence. Body weight and diarrhea occurrence were also retrospectively analyzed in an additional 120 adolescent rhesus who underwent a similar transfer. RESULTS AND CONCLUSIONS: Pair-housed macaques exhibited less of some undesirable behaviors (e.g., self-clasping) and experienced less diarrhea than single-housed subjects; however, no significant differences in cortisol levels or alopecia measures were found. The demonstrated beneficial effects of pair housing for rhesus macaques following intrafacility transfer and adjustment suggest pairing upon arrival at a new facility will bolster animal welfare.

Gendered Racial Microaggressions and Black Women's Sleep Health.

Gendered racial microaggressions reflect historical and contemporary gendered racism that Black women encounter. Although gendered racial microaggressions are related to psychological outcomes, it is unclear if such experiences are related to sleep health. Moreover, the health effects of gendered racial microaggressions dimensions are rarely investigated. Using a cohort of Black women (N = 400), this study employs an intracategorical intersectional approach to (1) investigate the association between gendered racial microaggressions and sleep health, (2) assess whether gendered racial microaggressions dimensions are related to sleep health, and (3) examine whether the gendered racial microaggressions-sleep health association persists after accounting for depressive symptoms and worry. Gendered racial microaggressions were associated with poor sleep quality overall and four specific domains: subjective sleep quality, latency, disturbance, and daytime sleepiness. Two gendered racial microaggressions dimensions were especially detrimental for sleep: assumptions of beauty/sexual objectification and feeling silenced and marginalized. After accounting for mental health, the effect of gendered racial microaggressions on sleep was reduced by 47 percent. Future research implications are discussed.

Nested and multipart prospective observational studies, flaming fiasco or efficiently economical?: The Brain, Bone, Heart case study.

BACKGROUND: Collecting new data from cross-sectional/survey and cohort observational study designs can be expensive and time-consuming. Nested (hierarchically cocooned within an existing parent study) and/or Multipart (≥ 2 integrally interlinked projects) study designs can expand the scope of a prospective observational research program beyond what might otherwise be possible with available funding and personnel. The Brain, Bone, Heart (BBH) study provides an exemplary case to describe the real-world advantages, challenges, considerations, and insights from these complex designs. MAIN: BBH is a Nested, Multipart study conducted by the Specialized Center for Research Excellence (SCORE) on Sex Differences at Emory University. BBH is designed to examine whether estrogen insufficiency-induced inflammation compounds HIV-induced inflammation, leading to end-organ damage and aging-related co-morbidities affecting the neuro-hypothalamic-pituitary-adrenal axis (brain), musculoskeletal (bone), and cardiovascular (heart) organ systems. Using BBH as a real-world case study, we describe the advantages and challenges of Nested and Multipart prospective cohort study design in practice. While excessive dependence on its parent study can pose challenges in a Nested study, there are significant advantages to the study design as well. These include the ability to leverage a parent study's resources and personnel; more comprehensive data collection and data sharing options; a broadened community of researchers for collaboration; dedicated longitudinal research participants; and, access to historical data. Multipart, interlinked studies that share a common cohort of participants and pool of resources have the advantage of dedicated key personnel and the challenge of increased organizational complexity. Important considerations for each study design include the stability and administration of the parent study (Nested) and the cohesiveness of linkage elements and staff organizational capacity (Multipart). CONCLUSION: Using the experience of BBH as an example, Nested and/or Multipart study designs have both distinct advantages and potential vulnerabilities that warrant consideration and require strong biostatistics and data management leadership to optimize programmatic success and impact.

Implementation of an EMS protocol to improve prehospital sepsis recognition.

PURPOSE: Optimal sepsis outcomes are achieved when sepsis is recognized early. Recognizing sepsis in the prehospital, EMS setting can be challenging and unreliable. The purpose of this study is to evaluate whether implementation of an EMS sepsis screening and prehospital alert protocol called PRESS (PREhospital SepsiS) is associated with improved sepsis recognition by EMS providers. DESIGN: We conducted a 12-month, before-after implementation study of the PRESS protocol in a large, public EMS system. The study intervention was a PRESS training program delivered to EMS providers. EMS patient inclusion criteria included: age ≥ 18 years, EMS systolic blood pressure < 110 mmHg, EMS heart rate > 90 bpm, and EMS respiratory rate > 20 bpm. Study exclusion criteria included the presence of any of following EMS conditions: trauma, cardiac arrest, pregnancy, toxic ingestion, or psychiatric emergency. Retrospective chart review was performed on all eligible EMS encounters during the study period. The primary outcome variable was the proportion of patients with sepsis who were identified by EMS providers. RESULTS: Approximately 300 EMS providers were trained to use PRESS. A total of 498 patient encounters met criteria for study inclusion; 222 were excluded, primarily due to trauma. A total of 276 patient encounters were analyzed. Sepsis recognition by EMS providers increased from 12% pre-PRESS protocol to 59% post-PRESS protocol (p < 0.001). In a post-hoc analysis of the post-PRESS cohort, septic patients who were identified by EMS received antibiotics 24 min faster than septic patients who were not identified by EMS [28 min (IQR 18-48) vs 52 (IQR 27-98), respectively, p = 0.021]. CONCLUSION: Implementation of an EMS sepsis screening and prehospital alert protocol was associated with an increase in sepsis recognition rates by EMS providers and a decrease in time to first antibiotic administration in the emergency department. Further studies are needed to evaluate the impact of this protocol in other populations.

Data and Safety Monitoring of COVID-19 Vaccine Clinical Trials.

To speed the development of vaccines against SARS-CoV-2, the United States Federal Government has funded multiple phase 3 trials of candidate vaccines. A single 11-member data and safety monitoring board (DSMB) monitors all government-funded trials to ensure coordinated oversight, promote harmonized designs, and allow shared insights related to safety across trials. DSMB reviews encompass 3 domains: (1) the conduct of trials, including overall and subgroup accrual and data quality and completeness; (2) safety, including individual events of concern and comparisons by randomized group; and (3) interim analyses of efficacy when event-driven milestones are met. Challenges have included the scale and pace of the trials, the frequency of safety events related to the combined enrollment of over 100 000 participants, many of whom are older adults or have comorbid conditions that place them at independent risk of serious health events, and the politicized environment in which the trials have taken place.

Health care practitioners' experience-based opinions on providing care after a positive newborn screen for Pompe disease.

The addition of Pompe disease (PD) and other conditions with later-onset forms to newborn screening (NBS) in the United States (US) has been controversial. NBS technology cannot discern infantile-onset PD (IOPD) from later-onset PD (LOPD) without clinical follow-up. This study explores genetic health care practitioners' (HCPs) experiences and challenges providing NBS patient care throughout the US and their resultant opinions on NBS for PD. An online survey was distributed to genetic counselors, geneticists, NBS follow-up care coordinators, and nurse practitioners caring for patients with positive NBS results for PD. Analysis of 78 surveys revealed the majority of participating HCPs support inclusion of PD on NBS. Almost all HCPs (93.3%) feel their state has sufficient resources to provide follow-up medical care for IOPD; however, only three-fourths (74.6%) believed this for LOPD. Common barriers included time lag between NBS and confirmatory results, insurance difficulties for laboratory testing, and family difficulties in seeking medical care. HCPs more frequently encountered barriers providing care for LOPD than IOPD (53.9% LOPD identified ≥3 barriers, 31.1% IOPD). HCPs also believe creation of a population of presymptomatic individuals with LOPD creates a psychological burden on the family (87.3% agree/strongly agree), unnecessary medicalization of the child (63.5% agree/strongly agree), and parental hypervigilance (68.3% agree/strongly agree). Opinions were markedly divided on the use of reproductive benefit as a justification for NBS. Participants believe additional education for pediatricians and other specialists would be beneficial in providing care for patients with both IOPD and LOPD, in addition to the creation of evidence-based official guidelines for care and supportive resources for families with LOPD.

Antibodies to human leukocyte antigens and their association with blood product exposures in pediatric patients undergoing cardiac transplantation.

BACKGROUND AND AIMS: Previous blood product exposures may result in the development of antibodies to human leukocyte antigens (HLA). Pediatric heart transplant recipients who have these antibodies experience increased morbidity and mortality after transplantation. In this study, our aims were to confirm the association of previous allogeneic blood product exposures with the formation of anti-HLA antibodies, determine which blood components pose the greatest risk of developing antibodies, and assess differences in outcomes after transplantation between patients who had anti-HLA antibodies and those who did not. METHODS: This retrospective investigation included all children who underwent cardiac transplantation at Children's Healthcare of Atlanta from January 1, 2015 through December 31, 2018. Chart reviews were performed to collect pertinent data. Anti-HLA antibodies were detected by single antigen bead testing. Antibody burden was tabulated using the calculated panel reactive antibody (cPRA) score immediately prior to transplantation. Statistical analyses were conducted to examine differences based on HLA antibody status and identify associations with outcomes of interest. RESULTS: Our results show a significant association between pretransplant blood product exposures and HLA antibody status. Children with a pretransplant blood product exposure had 7.98 times the odds of developing an anti-HLA antibody compared to those without a pretransplant blood product exposure (p = .01). We also found a significant association between a previous red blood cell (RBC) exposure and HLA antibody status (p = .01) which was not found for other blood component exposures. Patients who were HLA antibody positive were more likely to develop a donor-specific antibody (DSA) after transplantation (p = .04). CONCLUSIONS: Exposure to previous allogeneic blood products affects the development of anti-HLA antibodies in children presenting for heart transplantation. Previous RBC exposures resulted in HLA antibody positivity more than other blood component exposures. Importantly, the presence of HLA antibodies was associated with the development of DSAs post-transplantation. Developing transfusion strategies to reduce allogeneic blood product exposures in children who may need future cardiac transplantation should be a high priority.

Nicardipine Prolonged Release Implants for Prevention of Delayed Cerebral Ischemia after Aneurysmal Subarachnoid Hemorrhage: A Meta-Analysis.

OBJECTIVES: A paucity of treatments to prevent delayed cerebral ischemia (DCI) has stymied recovery after aneurysmal subarachnoid hemorrhage (aSAH). Nicardipine has long been recognized as a potent cerebrovascular vasodilator with a history off-label use to prevent vasospasm and DCI. Multiple centers have developed nicardipine prolonged release implants (NPRI) that are directly applied during clip ligation to locally deliver nicardipine throughout the vasospasm window. Here we perform a systematic review and meta-analysis to assess whether NPRI confers protection against DCI and improves functional outcomes after aSAH. MATERIALS AND METHODS: A systematic search of PubMed, Ovid Embase, and Cochrane databases was performed for studies reporting the use of NPRI after aSAH published after January 1, 1980. We included all studies assessing the association of NPRI with DCI and or functional outcomes. Findings from studies with control arms were analyzed using a random effects model. A separate network meta-analysis was performed, including controlled NPRI studies, single-arm NPRI reports, and the control-arms of modern aSAH randomized clinical trials as additional comparators. RESULTS: The search identified 214 unique citations. Three studies with 284 patients met criteria for the random effects model. The pooled summary odds ratio for the association of NPRI and DCI was 0.21 (95% CI 0.09-0.49, p = 0.0002) with no difference in functional outcomes (OR 1.80, 95% CI 0.63 - 5.16, p = 0.28). 10 studies of 866 patients met criteria for the network meta-analysis. The pooled summary odds ratio for the association of NPRI and DCI was 0.30 (95% CI 0.13-0.89,p = 0.017) with a trend towards improved functional outcomes (OR 1.68, 0.63 - 4.13 95% CI, p = 0.101). CONCLUSIONS: In these meta-analyses, NPRI decreases the incidence of DCI with a non-significant trend towards improvement in functional outcomes. Randomized trials on the role of intrathecal calcium channel blockers are warranted to evaluate these observations in a prospective manner.

Antibody-Dependent Enhancement of Severe Disease Is Mediated by Serum Viral Load in Pediatric Dengue Virus Infections.

BACKGROUND: Low preexisting anti-dengue virus (DENV) antibody levels are associated with elevated disease severity. While antibody-dependent enhancement of dengue is thought to be driven by viral load, this has not been conclusively shown. We evaluated the association between preinfection anti-DENV antibody titers, viral load, and disease severity among 133 dengue cases in a Nicaraguan pediatric cohort study. METHODS: Viral load was quantified in acute-phase serum by real-time reverse transcription polymerase chain reaction and analyzed in relation to preinfection antibody titer (measured by inhibition enzyme-linked immunosorbent assay) and dengue severity, categorized using 3 definitions. RESULTS: Higher viral load was significantly associated with dengue severity; for each increase of 1.0 log10 copies/mL, the odds of severe dengue increased approximately 50%, regardless of severity definition. Viral load at presentation and the odds of severe disease were highest among patients with low to intermediate preinfection antibody titers and lowest among those with the highest antibody titers. We showed the effect of preinfection antibody titer on disease severity was mediated by viral load for each of 3 dengue severity outcomes. CONCLUSIONS: This study demonstrates the association between preinfection anti-DENV antibody titer, serum viral load, and disease severity, and provides evidence for the mechanism of antibody-dependent enhancement in dengue cases.

Increased parental anxiety and a benign clinical course: Infants identified with short-chain acyl-CoA dehydrogenase deficiency and isobutyryl-CoA dehydrogenase deficiency through newborn screening in Georgia.

The long-term consequences and need for therapy in children with short-chain acyl-CoA dehydrogenase deficiency (SCADD) or isobutyryl-CoA dehydrogenase deficiency (IBDD) identified via newborn screening (NBS) remains controversial. Initial clinical descriptions were severe; however, while most cases identified through NBS have remained asymptomatic, clinical concerns have been raised in these populations. It is not clear whether these children are asymptomatic because of the success of NBS, or because the normal clinical course of these disorders is relatively benign. To evaluate these possibilities in our program, we evaluated the clinical outcomes of children with SCADD or IBDD identified by the Georgia NBS compared to the health status of a healthy age-matched control group. We also assessed parental anxiety during a phone interview both subjectively and objectively using the Pediatric Inventory for Parents (PIP), a validated measure of illness-related parental stress. The general health of 52 SCADD and nine IBDD cases from 2007 to 2016 were compared to the general health of unaffected control children obtained through the Centers for Disease Control and Prevention (CDC) parent listserv. We also collected statements from parents who participated in a phone survey regarding events they experienced during and after their diagnostic process. Overall, the children with SCADD and IBDD had no major health problems. There was no significant difference in cognitive development (p = .207). We identified a slightly higher incidence of reported neonatal hypoglycemia in the SCADD group; two of these occurred in the context of maternal diabetes. All interviewed parents reported extreme anxiety during the diagnostic period and current feelings of uncertainty about their child's future. PIP scores for all six caregivers who responded to that portion of the survey were consistent with some degree of parental stress. The greatest reported stressor was the unknown long-term impact of the illness. All children with SCADD and IBDD had no significant long-term sequelae. The phone interviews revealed substantial parental anxiety about the identification and follow-up of SCADD and IBDD. Based on our findings, the anxiety parents experience may be unwarranted given that we see no disease-associated morbidity or mortality in these children. Consideration should be given to the removal of these conditions from NBS panels, or if that is not possible, clinicians could educate parents on the benign nature of these diagnoses and release them from follow-up without treatment.

Gabapentin as an adjunct to paracervical block for perioperative pain management for first-trimester uterine aspiration: a randomized controlled trial.

BACKGROUND: Pain management approaches during uterine aspiration vary, which include local anesthetic, oral analgesics, moderate sedation, deep sedation, or a combination of approaches. For local anesthetic approaches specifically, we continue to have suboptimal pain control. Gabapentin as an adjunct to pain management has proven to be beneficial in gynecologic surgery. We sought to evaluate the impact of gabapentin on perioperative pain during surgical management of first-trimester abortion or early pregnancy loss with uterine aspiration under local anesthesia. OBJECTIVE: We hypothesized that adding gabapentin to local anesthesia will reduce perioperative and postoperative pain associated with uterine aspiration. Secondary outcomes included tolerability of gabapentin and postoperative pain, nausea, vomiting, and anxiety. STUDY DESIGN: We conducted a randomized double-blinded placebo-controlled trial of gabapentin 600 mg given 1 to 2 hours preoperatively among subjects receiving a first-trimester uterine aspiration under paracervical block in an outpatient ambulatory surgery center. There were 111 subjects randomized. The primary outcome was pain at time of uterine aspiration as measured on a 100-mm visual analog scale. Secondary outcomes included pain at other perioperative time points. To assess changes in pain measures, an intention to treat mixed effects model was fit with treatment groups (gabapentin vs control) as a between-subjects factor and time point as a within-subjects factor plus their interaction term. Because of a non-normal distribution of pain scores, the area under the curve was calculated for secondary outcomes with comparison of groups utilizing Mann-Whitney U tests. RESULTS: Among the 111 randomized, most subjects were Black or African American (69.4%), mean age was 26 years (±5.5), and mean gestational age was 61.3 days (standard deviation, 14.10). Mean pain scores at time of uterine aspiration were 66.77 (gabapentin) vs 71.06 (placebo), with a mean difference of -3.38 (P=.51). There were no significant changes in pain score preoperatively or intraoperatively. Subjects who received gabapentin had significantly lower levels of pain at 10 minutes after surgery (mean difference [standard error (SE)]=-13.0 [-5.0]; P=.01) and 30 minutes after surgery (mean difference [SE]=-10.8 [-5.1]; P=.03) compared with subjects who received placebo. Median nausea scores and incidence of emesis pre- and postoperatively did not differ between groups. Similarly, anxiety scores did not differ between groups, before or after the procedure. At 10 and 30 minutes after the procedure, most participants reported no side effects or mild side effects, and this did not differ between groups. CONCLUSION: Preoperative gabapentin did not reduce pain during uterine aspiration. However, it did reduce postoperative pain, which may prove to be a desired attribute of its use, particularly in cases where postoperative pain may be a greater challenge.

Caloric compensation and appetite control in children of different weight status and predisposition to obesity.

To prevent childhood obesity it is critical to identify behavioral phenotypes for overeating, especially among children who are predisposed to obesity. We examined caloric compensation and appetite control in 212 normal-weight (NW) and obese (OB) children, ages 7 to 9, who were at high risk (HR) or low risk (LR) for obesity based on maternal obesity. In a within-subjects crossover design, children ate breakfast, lunch, dinner, and snacks in the laboratory once a week for two weeks. Children's percentage compensation index (%COMPX) was computed at breakfast. Twenty-five minutes before breakfast, children received one of two compulsory preloads, which varied in energy density (ED) and caloric content [Low ED (LED): 1.00 kcal/g; 100 kcal; High ED (HED): 1.60 kcal/g; 160 kcal]. Children's appetite was measured hourly using Visual Analog Scales, which were used to compute 3-h post-prandial area under the curve (AUCs) after breakfast and the satiety quotient (SQ), which allows between-group comparisons of a fixed amount of a food's potency to reduce appetite sensations per unit of intake. There were no significant differences in %COMPX, SQ, or AUC among LR-NW, HR-NW, and HR-OB children (P > 0.10). SQs for Hunger and Prospective Consumption were higher and SQ for Fullness lower after consuming the LED compared to the HED preload (P < 0.009). Further, the SQ and AUC for Desire to Eat and AUC for Prospective Consumption significantly predicted energy intake during the remainder of the day (P < 0.03). In this study, HR-NW children did not differ from LR-NW or HR-OB children in their caloric compensation or appetite control. Foods with a high satiating effect may facilitate appetite control and help to moderate daily energy intake in all children, including at-risk children.

Utility of a US Food and Drug Administration (FDA) label indication for condoms for anal sex.

Condoms are highly effective for HIV prevention, yet are not currently indicated by the US Food and Drug Administration (FDA) for anal sex. We surveyed a national sample of men who have sex with men to assess whether FDA label indication could affect anticipated condom use, and to determine levels of perceived condom failure for anal sex. We found that 69% of respondents anticipated that a label indication change would increase their likelihood of condom use. Median perceived failure was 15%. We anticipate that these results may aid the FDA in developing standards for a label indication for anal sex.

Patients' reactions and follow-up testing decisions related to Tay-Sachs (HEXA) variants of uncertain significance results.

JScreen is a national public health initiative based out of Emory University that provides reproductive carrier screening through an online portal and follow-up genetic counseling services. In 2014, JScreen began reporting to patients variants of uncertain significance (VUSs) in the gene that causes Tay-Sachs disease (HEXA). Genetic counseling was provided to discuss the VUS and patients were offered hexosaminidase A (HEXA) blood enzyme testing to assist with VUS reclassification. To identify patient reactions and factors influencing their follow-up testing decisions after receiving these results, we conducted a retrospective quantitative study by administering online surveys to 62 patients with HEXA VUSs. Participants who pursued enzyme testing and those who did not both experienced low levels of distress when receiving the VUS results. Perceptions of HEXA carrier status after genetic counseling, decisional conflict levels, plans to have children in the near future, time available to pursue enzyme testing, and eligibility for research were significant factors influencing decision-making to pursue or not pursue enzyme testing. Genetic counseling played an important role in helping patients understand the VUS and follow-up testing options. When discussing VUSs with patients, it would be beneficial for genetic counselors to focus on the patient's perception of the VUS, anxiety related to the uncertainty of their results, and follow-up options, when available.

Identifying behavioral phenotypes for childhood obesity.

Existing programs which aim to prevent and treat childhood obesity often do not take into account individual variation and the underlying mechanisms that impact child eating behavior. Individual differences in children's appetitive traits have been shown to appear as early as during infancy and become more pronounced as children grow older and become more exposed to the obesogenic food environment. Differences in genetic predispositions interacting with factors in children's early environment account in part for individual differences in appetitive traits. It is very likely that obesogenic eating phenotypes manifest themselves before the onset of childhood obesity. If so, identifying these phenotypes early is expected to move primary prevention strategies in a new direction and holds great potential to significantly enhance our ability to prevent childhood obesity. The aim of this narrative review is to discuss the role of behavioral phenotyping as an innovative approach for the development of more personalized obesity prevention and treatment interventions that are tailored to children's individual predispositions. We describe several examples of appetitive traits which have been linked to overeating and excess weight gain in children and thus may represent modifiable risk factors for future interventions. The review concludes with a comprehensive synthesis of opportunities for future human ingestive behavior research on identifying behavioral phenotypes for childhood obesity.

Feasibility of autologous intraoperative blood collection and retransfusion in small children with complex congenital heart defects undergoing cardiopulmonary bypass.

INTRODUCTION: Allogeneic blood product transfusion is common in pediatric patients undergoing cardiopulmonary bypass although it is associated with an increased risk for adverse events. Furthermore, numerous donor exposures may affect future blood transfusion needs and human leukocyte antigen matching for patients who may ultimately require cardiac transplantation. Autologous intraoperative blood collection and retransfusion is a known method of blood preservation, but has not been extensively practiced in pediatric patients. In this study we assess the feasibility of this blood conservation technique in small children with complex congenital heart defects undergoing cardiopulmonary bypass. METHODS: After Institutional Review Board approval, we retrospectively reviewed the medical records of children weighing <10 kg who underwent cardiopulmonary bypass over a 2-year period. Eighteen patients underwent autologous intraoperative blood collection and retransfusion and comprised the study group. Eighteen control patients were chosen by a 1:1 matched design using preoperative hematocrit, surgical procedure, and body weight. Multiple corresponding demographic and surgical variables, transfusion data, and clinical outcomes were compared. RESULTS: Patient demographics, operative parameters and preoperative laboratory, and coagulation values were similar between the two groups. Despite the removal of autologous blood, study patients did not require more inotropic support prior to cardiopulmonary bypass. They also did not experience a significant increase in bleeding as measured by 24-hour postoperative chest tube output. Study patients were exposed to significantly fewer donor units intraoperatively and within the first 24 hours postoperatively. DISCUSSION: The use of autologous intraoperative blood collection and retransfusion is a feasible option for small children with complex congenital heart defects undergoing cardiopulmonary bypass. Study patients received significantly fewer donor exposures without an increase in postoperative bleeding. Children who require multiple cardiac surgeries or eventually transplantation could benefit from this blood conservation technique.

Operation family caregiver: Problem-solving training for military caregivers in a community setting.

OBJECTIVE: This study, conducted over a 2-year period at 9 sites, describes the outcomes of an evidence-based support program, Operation Family Caregiver, to gain an understanding of how a tailored, problem-solving training could assist military caregivers, who provide care and assistance to those injured, ill, or disabled as a result of war. METHOD: A pre-post research design was employed to examine caregiver burden, depression, health complaints, satisfaction with life, children's anxiety, and problem solving among a convenience sample of caregivers of 128 military service members and veterans. RESULTS: Analysis revealed a decrease in depression, burden, and health complaints and an increase in satisfaction of life and positive problem-solving skills (p < .001). CONCLUSION: This program may be beneficial to caregiving families of military service and veterans living with posttraumatic stress, traumatic brain injury, and/or a physical disability.

Preventing Weight Gain Improves Sleep Quality Among Black Women: Results from a RCT.

BACKGROUND: Obesity and poor sleep are highly prevalent among Black women. PURPOSE: We examined whether a weight gain prevention intervention improved sleep among Black women. METHODS: We conducted a randomized trial comparing a 12-month weight gain prevention intervention that included self-monitoring through mobile technologies and phone coaching to usual care in community health centers. We measured sleep using the Medical Outcomes Study Sleep Scale at baseline, 12 months, and 18 months. The scale examines quantity of sleep, sleep disturbance, sleep adequacy, daytime somnolence, snoring, shortness of breath, and global sleep problems (sleep problem indices I and II). RESULTS: Participants (n = 184) were on average 35.4 years and obese (BMI 30.2 kg/m2); 74% made <$30,000/year. At baseline, average sleep duration was 6.4 (1.5) hours. Controlling for weight change and sleep medication, the intervention group reported greater improvements in sleep disturbance [-8.35 (-16.24, -0.45)] and sleep problems at 12 months: sleep problem index I [-8.35 (-16.24, -0.45)]; sleep problem index II [-8.35 (-16.24, -0.45)]. However, these findings did not persist at 18 months. CONCLUSIONS: Preventing weight gain may afford clinical benefit on improving sleep quality. TRIAL REGISTRATION NUMBER: The trial was registered with the ClinicalTrials.gov database (NCT00938535).

A randomized trial of adenotonsillectomy for childhood sleep apnea.

BACKGROUND: Adenotonsillectomy is commonly performed in children with the obstructive sleep apnea syndrome, yet its usefulness in reducing symptoms and improving cognition, behavior, quality of life, and polysomnographic findings has not been rigorously evaluated. We hypothesized that, in children with the obstructive sleep apnea syndrome without prolonged oxyhemoglobin desaturation, early adenotonsillectomy, as compared with watchful waiting with supportive care, would result in improved outcomes. METHODS: We randomly assigned 464 children, 5 to 9 years of age, with the obstructive sleep apnea syndrome to early adenotonsillectomy or a strategy of watchful waiting. Polysomnographic, cognitive, behavioral, and health outcomes were assessed at baseline and at 7 months. RESULTS: The average baseline value for the primary outcome, the attention and executive-function score on the Developmental Neuropsychological Assessment (with scores ranging from 50 to 150 and higher scores indicating better functioning), was close to the population mean of 100, and the change from baseline to follow-up did not differ significantly according to study group (mean [±SD] improvement, 7.1±13.9 in the early-adenotonsillectomy group and 5.1±13.4 in the watchful-waiting group; P=0.16). In contrast, there were significantly greater improvements in behavioral, quality-of-life, and polysomnographic findings and significantly greater reduction in symptoms in the early-adenotonsillectomy group than in the watchful-waiting group. Normalization of polysomnographic findings was observed in a larger proportion of children in the early-adenotonsillectomy group than in the watchful-waiting group (79% vs. 46%). CONCLUSIONS: As compared with a strategy of watchful waiting, surgical treatment for the obstructive sleep apnea syndrome in school-age children did not significantly improve attention or executive function as measured by neuropsychological testing but did reduce symptoms and improve secondary outcomes of behavior, quality of life, and polysomnographic findings, thus providing evidence of beneficial effects of early adenotonsillectomy.
