Predictors of Mortality and Revision Following Digital Amputation for Infection and Necrosis.

PURPOSE: Digital amputation is a commonly performed procedure for infection and necrosis in patients with diabetes, peripheral vascular disease (PVD), and on dialysis. There is a lack of data regarding prognosis for revision amputation and mortality following digital amputation in these patients. METHODS: All digital amputations over 10-year period (2008-2018) at a single center were reviewed. There were 484 amputations in 360 patients, among which 358 were performed for trauma (reference sample) and 126 for infection or necrosis (sample of interest). Patient death and revision were determined from National Vital Statistics System and medical records. Propensity score matching was performed to compare groups. Data were then compared to the Social Security Administration Actuarial Life Table for 2015 to determine age-matched expected mortality. RESULTS: The 2-year revision rate was 34% for amputations performed for infection or necrosis, compared to 15% for amputations due to trauma. For amputations performed for infection or necrosis, the revision rate was 47.7% when diabetes, PVD, and dialysis were present. Among all patients with infection or necrosis (n = 104) undergoing a digital amputation, overall survival at 2, 5, and 10 years was 79.4%, 57.3%, and 17.5%, respectively, which represented a 3.2-fold increased risk of death compared to controls. (hazard ratio, 3.19; 95% confidence interval, 1.47-6.93). For amputations due to trauma, mortality was no different from that in the age-matched general population. CONCLUSIONS: Mortality and revision risk are high for patients requiring a digital amputation for infection or necrosis and are further increased with medical comorbidities. Hand surgeons should consider the prognostic implications of these data when counseling patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Understanding the mediated relationship between moral distress, depression, and suicide risk in undergraduate nursing students.

BACKGROUND: Nursing students are at higher risk for depression, suicide, and other mental health concerns as compared to the general college student population. Moral distress and other ethical issues may be a significant source of psychological harm within nursing student experiences and warrants further attention. PURPOSE: The purpose of this study was to understand the mediating effect of depression on the relationship between moral distress and suicide risk among undergraduate nursing students. METHODS: This cross-sectional analysis was derived from a larger sequential mixed methods study. The first phase was an online survey completed by a national sample of N = 679 nursing students in the United States. FINDINGS: The relationship between moral distress and suicide risk was fully mediated by depression and statistically significant at the alpha = 0.05 level. CONCLUSION: All three psychological variables (depression, moral distress, suicide risk) impact nursing students and require innovative solutions within nursing and educational programs.

Medical Complexity Mediates Healthcare Resource Use in the Socially Vulnerable.

GOAL: The objective of this retrospective, observational study was to assess the mediating effect of medical complexity on the relationship between social vulnerability and four acute care resource use outcomes-number of hospitalizations, emergency department (ED) visits, observation stays, and total visits. Such information may help healthcare managers better anticipate the effects of interventions targeted to the socially vulnerable in their patient population. METHODS: Electronic health records of 147,496 adults served by 27 primary care practices in one large health system from 2015 to 2017 were used. Descriptive statistics were applied to characterize patients and the primary care practices included in the study. Causal mediation analyses using a modified Baron and Kenny approach were performed. PRINCIPAL FINDINGS: Causal mediation analyses demonstrated that increased social vulnerability was associated with increased medical complexity (incidence rate ratio [IRR] = 1.57) and increased numbers of hospitalizations (IRR = 1.63), ED visits (IRR = 2.14), observation stays (IRR = 1.94), and total visits (IRR = 2.04). Effects remained significant, though attenuated, after adjusting for medical complexity (mediator), demographics, and medications (hospitalizations IRR = 1.44, ED visits IRR = 2.02, observation stays IRR = 1.74, total visits IRR = 1.86). Social vulnerability, given medical complexity, explained between 8% (ED visits) and 26% (hospitalizations) of the variation in outcomes. PRACTICAL APPLICATIONS: These findings reinforce the need to modify interventions for medically complex adults to address their social needs and, consequently, reduce costly health services. Health systems seeking to reduce costly care can use these results to estimate savings in the treatment of patients with high social vulnerability-before they get chronic conditions and later as they seek care.

Parental Post-traumatic Stress and Healthcare Use in Infants with Complex Cardiac Defects.

OBJECTIVE: To examine the associations between post-traumatic stress of parents of infants with complex congenital heart defects and their healthcare use for their infants during the early months of life. STUDY DESIGN: The current study is a secondary data analysis from a randomized controlled trial in which 216 parent-infant dyads were recruited from 3 cardiac intensive care units of large pediatric centers in Northeastern America. The current sample included 153 dyads with post-traumatic stress data at hospital discharge and at 4-months' follow-up. Poisson regressions were used to estimate the effect of post-traumatic stress change scores on number of emergency department (ED) visits, unscheduled cardiologist visits, and unscheduled pediatrician visits outcomes. RESULTS: Infants whose parents gained post-traumatic stress disorder over the study period were at increased risk for ED visits and unscheduled cardiologist visits. Increased symptom severity predicted more unscheduled cardiologist visits and more unscheduled pediatrician visits. Increased symptom clusters (avoidance, arousal, re-experiencing) predicted more ED visits, more unscheduled cardiologist visits, and more unscheduled pediatrician visits. CONCLUSIONS: Parents of infants with cardiac conditions may experience post-traumatic stress following cardiac surgery, which can be linked to greater healthcare use. Findings highlight the importance of screening and treating post-traumatic stress to preserve parental mental health and prevent adverse outcomes.

Results from Project GOLD: A pilot randomized controlled trial of a psychoeducational HIV/STI prevention intervention for black youth.

Black youth face significant disparities in HIV/sexually transmitted infection (STI) disease burden. Mental illness and emotion regulation are ontributors to HIV/STI risk, yet many HIV/STI prevention interventions do not address these factors. Project GOLD was a pilot randomized controlled trial of a psychoeducational HIV/STI prevention intervention designed to address the role of mental illness and emotion regulation in HIV/STI risk among heterosexually active Black youth aged 14-17 (N = 108). Participants were recruited from outpatient mental health treatment programs and general community settings via community partner referrals, face-to-face encounters, flyers and social media. Assessments were conducted pretest, immediate posttest, and at 3-, 6-, and 12-month follow-up. Although there were no statistically significant differences in behavior change from baseline, there were practically significant effect sizes among HIV condition participants when compared to the general health condition (e.g., fewer sexual partners at 6 months). An increase in theoretical mediators (e.g., condom use negotiation beliefs) was sustained at 12 months. HIV condition participants also reported lower depressive symptom severity, with statistical significance noted at immediate post and at 3 months. The findings highlight the importance and challenges of engaging Black youth in culturally and contextually relevant, developmentally and psychologically appropriate HIV/STI prevention interventions.

One Year of Continuous Positive Airway Pressure Adherence Improves Cognition in Older Adults With Mild Apnea and Mild Cognitive Impairment.

BACKGROUND: Mild cognitive impairment frequently represents a predementia stage of Alzheimer's disease. Although obstructive sleep apnea is increasingly recognized as a common comorbidity of mild cognitive impairment, most apnea research has focused on middle-aged adults with moderate-to-severe obstructive sleep apnea. Mild obstructive sleep apnea, defined as 5-14 apneas or hypopneas per hour slept, is common in older adults. Little is known about the effect on cognition of adherence to continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea in older adults with mild obstructive sleep apnea and mild cognitive impairment. OBJECTIVE: The objective of this study was to explore the effect of CPAP adherence on cognition in older adults with mild obstructive sleep apnea and mild cognitive impairment. METHODS: We conducted a secondary analysis of data from Memories 1, a 1-year quasiexperimental clinical trial on the effect of CPAP adherence in older adults with mild cognitive impairment and obstructive sleep apnea. Those with mild obstructive sleep apnea were divided into two groups based on their CPAP adherence over 1 year: (a) CPAP adherent group (mild cognitive impairment + CPAP) with an average CPAP use of ≥4 hours per night and (b) CPAP nonadherent group (mild cognitive impairment - CPAP) with an average CPAP use of <4 hours per night. Individuals currently using CPAP were not eligible. A CPAP adherence intervention was provided for all participants, and an attention control intervention was provided for participants who chose to discontinue CPAP use during the 1-year follow-up. Descriptive baseline analyses, paired t tests for within-group changes, and general linear and logistic regression models for between-group changes were conducted. RESULTS: Those in the mild cognitive impairment + CPAP group compared to the mild cognitive impairment - CPAP group demonstrated a significant improvement in psychomotor/cognitive processing speed, measured by the Digit Symbol Coding Test. Eight participants improved on the Clinical Dementia Rating Scale, whereas six worsened or were unchanged. Twelve participants rated themselves as improved on the Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change Scale, whereas three reported their status as worsened or unchanged. The mild cognitive impairment + CPAP group had greater than an eightfold increased odds of improving on the Clinical Dementia Rating and greater than a ninefold increased odds of improving on the Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change Scale, compared to the mild cognitive impairment - CPAP group. DISCUSSION: CPAP adherence may be a promising intervention for slowing cognitive decline in older adults with mild obstructive sleep apnea and mild cognitive impairment. A larger, adequately powered study is needed.

Fear of falling in sensory impaired nursing home residents.

Objectives: Fear of falling (FOF) causes excess disability in nursing home (NH) residents and is associated with vision and hearing impairment. We explored factors associated with FOF in 225 NH residents with vision, hearing or dual sensory impairment.Methods: We explored age, gender, cognition, depression, social engagement, illness burden, falls, physical function, mobility, falls self-efficacy and outcome expectancy as predictors of FOF using univariate logistic regression modeling, followed by multivariate analysis by group (visual, hearing, dual, total sample).Results: Fifty-one percent of residents had FOF. Residents who had FOF reported better cognition, lower falls self-efficacy, and higher outcome expectancy in the total sample and in most impairment groups. Falls outcome expectancy predictedFOF in the total sample and in the visual and hearing sensory impairment groups.Conclusion: When addressing FOF in NH residents it is important to address sensory status along with fears about falling to promote function.

Testing the Efficacy of a Web-Based Parent-Adolescent Sexual Communication Intervention Among Puerto Ricans.

This randomized controlled trial tested the efficacy of a Web-based intervention to increase sexual communication between parents and adolescents. Parent/adolescent dyads (n = 660) were recruited from communities in the San Juan area and randomly assigned to the Cuídalos sexual communication or physical activity program. Parent assessments were obtained preintervention and at 3-, 6-, and 12-month follow-up. Parents in the experimental group reported significantly more sexual communication (ie, peer pressure, sexual prevention, protection, risk) over time than parents in the control group. Results support the efficacy of the Cuídalos Web-based format and provide insight into future Web-based sexual health interventions for this population.

Project GOLD: A pilot randomized controlled trial of a novel psychoeducational HIV/STI prevention intervention for heterosexually-active black youth.

Black youth account for the largest number of new HIV infections among heterosexual youth. Mental illness and difficulties in emotion regulation contribute to increased reports of HIV/sexually transmitted infection (STI) risk-related sexual behaviors in this group. Yet limited interventions exist to address this affective component of the sexual decision-making process. The purpose of this paper was to describe the trial design, research challenges, and baseline characteristics from a study designed to fill this gap. Project GOLD was a pilot randomized controlled trial of a psychoeducational HIV/STI prevention intervention designed to address the role of mental illness and emotion regulation in HIV/STI risk among heterosexually-active Black youth aged 14 to 17 (N = 108). Challenges encountered in the research process warrant further attention in future research (e.g., disagreement among the regulatory bodies on parental permission requirements). The most common mental health diagnoses were Recurrent Major Depressive Disorder (15.7%) and current substance abuse (7.4%). Participants reported higher levels of emotional suppression, and adaptive methods of emotion management, than culturally inappropriate expressions of anger or sadness. They also reported a mean age of 13.6 at first vaginal sex, used condoms 66% of the time for vaginal sex, and had an average of three sexual partners in the past 6 months. More than one-quarter (26.9%) had sex with more than one person in the same day. These findings indicate intervention is crucial for this population. The forthcoming trial evaluation will indicate the promise of such interventions in reducing HIV/STI infections in this key population.

Use of Web-Based Parent-Adolescent Health Promotion Program Among Puerto Ricans.

BACKGROUND: Despite positive attitudes of Latinos using the Internet and the increased availability of health information resources, few studies have been conducted that examine actual use and barriers to web-based health information. OBJECTIVE: The aim of this study was to examine whether select sociodemographic factors and technology factors (e.g., computer and Internet access) predicted use of a web-based, parent-adolescent sexual communication program or a physical activity program, entitled Cuídalos, among Puerto Rican parents. METHODS: This study uses data from a randomized controlled trial designed to examine the long-term effectiveness of Cuídalos. Parents were recruited from community-based and school sites throughout Puerto Rico and randomly assigned to a web-based, parent-adolescent sexual communication (n = 245) or a physical activity (n = 247) program. Parents were instructed to complete the two-session program within 1 week and had access to the program for a period of 3 months. Outcomes in this secondary analysis were the number of log-ins and self-reported access during the 3-month period. Reasons for not accessing the program after the 3-month period were assessed. RESULTS: Self-reported access after completion of the Cuídalos program and the actual number of log-ins over the intervention period were low. There were no statistically significant differences in the number of log-ins between parents who accessed Cuídalos during the 3-month time frame and those who did not (p = .28). Logistic regression analyses demonstrated that the odds of accessing Cuídalos during the 3-month period was 72% higher (OR = 1.72, 95% CI [1.08, 2.75]) among parents with a high school education or less, as compared to parents with a college education (p = .02). Similarly, Poisson regression model results indicated that, with every year increase in age, the expected number of log-ins increased by 1% (RR = 1.01, 95% CI [1.00, 1.02]); compared to those who accessed the program at home, the expected number of log-ins ranged from 10% to 27% lower for parents accessing elsewhere. Reasons for not accessing the program during the 3-month period included not having easy access to a computer (n = 134, 48.6%), or they did not know how to access the program again (n = 56, 20.3%). DISCUSSION: Despite the availability of web-based and e-health resources, further research is needed to identify how to facilitate greater access and actual use of digital health resources by Latinos. This is an important effort in order to prevent a widening health equity gap caused by a lack of access and use of digital health resources.

Internet and Social Media Access Among Youth Experiencing Homelessness: Mixed-Methods Study.

BACKGROUND: Youth experiencing homelessness are at a risk for a variety of adverse outcomes. Given the widespread use of the internet and social media, these new technologies may be used to address their needs and for outreach purposes. However, little is known about how this group uses these resources. OBJECTIVE: This study investigated how homeless adolescents use these technologies for general and health-related purposes, whether the scope of their use changes with housing status, and their interest in a website dedicated to youth experiencing homelessness. METHODS: A convenience sample of youth aged 18 to 21 years was recruited from a youth-specific homeless shelter. All participants completed a 47-item survey, with 10 individuals completing a semistructured interview. Descriptive statistics, exact testing, logistic regression, and generalized estimating equation modeling was performed for quantitative data analysis. Interviews were transcribed verbatim, and NVivo 10 (QSR International) was employed to facilitate double coding and thematic analysis. RESULTS: A total of 87 participants completed the survey with a mean age of 19.4 (SD 1.1) years. While experiencing homelessness, 56% (49/87) accessed the internet at least once a day, with 86% (75/87) accessing once a week. Access to a smartphone was associated with a 3.03 greater odds of accessing the internet and was the most frequently used device (66% of participants, 57/87). While experiencing homelessness, subjects reported a 68% decreased odds in internet access frequency (odds ratio [OR] 0.32, P<.001), 75% decreased odds in spending greater amounts of time on the internet (OR 0.25, P<.001), and an 87% decreased odds of social media use (OR 0.13, P=.01). Ten participants completed the semistructured interview. Several themes were identified, including (1) changes in internet behaviors while experiencing homelessness, (2) health status as a major concern and reason for Internet use, and (3) interest in a website dedicated to youth experiencing homelessness. While experiencing homelessness, participants indicated their behaviors were more goal-oriented and less focused on leisure or entertainment activities. CONCLUSIONS: While homeless youth experience changes in the frequency, amount of time, and specific uses of the internet and social media, study participants were able to access the internet regularly. The internet was used to search health-related topics. Given the importance of smartphones in accessing the internet, mobile-optimized websites may be an effective method for reaching this group.

Food Insecurity and Cardiometabolic Risk Factors in Adolescents.

INTRODUCTION: Food insecurity is associated with poor cardiometabolic health in adults. The extent to which this relationship exists in adolescents has yet to be defined. The objective of this study was to examine the relationship between food insecurity and cardiometabolic risk factors in adolescents. METHODS: We evaluated the association between food insecurity and several cardiometabolic risk factors by using data collected from the Youth Risk Behavior Survey at the state and city levels. Logistic regression models adjusted for sex, race/ethnicity, grade, and neighborhood safety were used to determine the association between food insecurity and cardiometabolic risk factors among a weighted sample of 495,509 adolescents. RESULTS: Of the sample studied, 12.8% reported being food insecure. Food-insecure adolescents had more than a twofold increased odds of not eating breakfast on all 7 days (adjusted odds ratio [AOR] = 2.27; 95% confidence interval [CI], 1.61-3.21; P < .001), a 60% increased odds of reporting less than 8 hours per day of sleep (AOR = 1.60; 95% CI, 1.15-2.23; P = .006), a 65% increased odds of reporting current cigarette smoking (AOR = 1.65; 95% CI, 1.16-2.36; P = .006), and a 65 % increased odds of current alcohol consumption (AOR = 1.36; CI, 1.01-1.84; P = .04), compared with food-secure adolescents. CONCLUSION: Among adolescents, in adjusted models, food insecurity was significantly associated with not consuming breakfast daily, getting less than 8 hours of sleep per day, currently smoking, and currently drinking alcohol. Food insecurity in adolescents may serve as an important precursor to poor cardiometabolic health.

Periodontal Pocket Therapy Using a Class IV Dental Diode Laser in Dogs: A Retrospective Analysis.

Class IV dental diode lasers have been introduced as a nonsurgical therapy for periodontal pockets in veterinary and human dentistry. This retrospective case series evaluates the use of Class IV dental diode laser therapy for abnormal periodontal pockets in a specialty veterinary dental practice. A hypothesis that the Class IV diode dental laser is a useful adjuvant modality in canine periodontal pocket therapy in the reduction of clinical pocket depth was made. This article discusses and demonstrates diode laser use in periodontal pocket therapy in a specialty veterinary dental practice and reviews the current literature. Inclusion in this study was limited to client-owned dogs with noted periodontal pocketing on any tooth type between 3 and 6 mm, which were treated with closed root planing (RP/C) and laser therapy who returned in 6 to 7 months for recheck of the pockets from the years 2017 to 2020. Twelve patients met the inclusion criteria. A total of 128 periodontal pockets were included in the study. Each periodontal pocket was a case receiving therapy. The mean periodontal pocket depth before the treatment is measured as 3.35 mm. The mean pocket depth of the periodontal pockets following treatment was 0.59 mm. The mean improvement in periodontal pocket depths after diode laser therapy when considering patient and tooth number using linear mixed-effects modeling was 2.63 mm (95% confidence interval [CI]: 1.81-3.46, P < .0001). No statistically significant results were observed for pocket type, as P values were greater than .05.

A Randomized Trial of Healthy Weight Gain in Athletic Individuals.

PURPOSE: The purpose of this study is to evaluate the outcomes of a 10-wk diet and exercise regimen designed to promote healthy weight gain with excess energy from peanut-containing or high-carbohydrate foods. METHODS: Nineteen male and 13 female athletes were randomly assigned to receive an additional 500 kcal·d -1 above typical intake through provision of either peanut-based whole foods/snacks (PNT group) or a similar, high-carbohydrate, peanut-free snack (CHO group) along with supervised, whole-body RT (3 d·wk -1 for 60-120 min). Body composition was assessed by dual-energyx-ray absorptiometry at baseline and postintervention. RESULTS: Total body mass (TBM) increased 2.2 ± 1.3 kg with 1.5 ± 1.1 kg as LBM after week 10. The PNT group ( n = 16; 27 ± 7 yr; 10 men, 6 women) gained less TBM than the CHO group ( n = 16; 23 ± 3 yr; 9 men, 7 women) (1.6 ± 1.1 kg vs 2.7 ± 1.2 kg, respectively, P = 0.007) with no differences in LBM (1.2 ± 1.1 kg vs 1.9 ± 1.0 kg, P = 0.136). CONCLUSIONS: These results suggest that the addition of 500 kcal·d -1 from whole foods/snacks in combination with a rigorous RT program promotes a similar weight gain of ~0.22 kg·wk -1 , primarily as LBM, over 10 wk in both male and female athletes. However, snack macronutrient content may impact the effectiveness of this regimen.

Association of chronotropic incompetence with reduced cardiorespiratory fitness in older adults with HIV.

OBJECTIVE: Understanding the physiological drivers of reduced cardiorespiratory fitness in people with HIV (PWH) will inform strategies to optimize healthspan. Chronotropic incompetence is common in heart failure and associated with low cardiorespiratory fitness yet is understudied in PWH. The objective was to determine the prevalence of chronotropic incompetence and its relationship with cardiorespiratory fitness. DESIGN: Participants were PWH at least 50 years of age with no prior history of heart failure or coronary heart disease who were enrolled in a randomized exercise trial. Baseline cardiopulmonary exercise testing (CPET) was used to measure cardiorespiratory fitness as peak oxygen consumption (VO2peak) and calculate the chronotropic index from heart rate values. Chronotropic incompetence was defined as an index less than 80%. RESULTS: The 74 participants were on average 61 years old, 80% Black or African American, and 93% men. Chronotropic incompetence was present in 31.1%. VO2peak was significantly lower among participants with chronotropic incompetence compared with participants without chronotropic incompetence [mean (SD) ml/min/kg: 20.9 (5.1) vs. 25.0 (4.5), P = 0.001]. Linear regression showed that chronotropic incompetence and age were independent predictors of VO2peak, but smoking and comorbidity were not. The chronotropic index correlated with VO2peak (r = 0.48, P < 0.001). CONCLUSION: Among older PWH without heart failure or coronary heart disease, chronotropic incompetence was present in approximately one-third of individuals and was associated with clinically relevant impaired cardiorespiratory fitness. Investigation of chronotropic incompetence in large cohorts which includes PWH and heart failure may contribute to strategies that promote healthy aging with HIV infection and offer a preclinical window for intervention.

Community Culture Survey - Revised: Measuring neighborhood culture and exploring geographic, socioeconomic, and cultural determinants of health in samples across the United States and in Thailand.

Objectives: Research on links between social, geographic, and cultural determinants of health has been thwarted by inadequate measures of culture. The purpose of this study was to improve the measurement of community culture, defined as shared patterns of attitudes and behaviors among people within a neighborhood that distinguish it from others, and to examine dimensions of culture, independent of socioeconomic and demographic factors, and their relationships with health. Study design: A survey research design with correlational analyses was used. Methods: A survey packet including the Community Culture Survey - Revised (CCS-R), demographic, health, and other individual-level measures was administered through convenience sampling across the United States (US) and to a sample in Thailand from 2016 to 2018. US county-level variables were obtained from zip codes. Results: 1930 participants from 49 US states (n = 1592) and Thailand (n = 338) completed all CCS-R items, from which 12 subscales were derived: Social Support & Connectedness, Responsibility for Self & Others, Family Ties & Duties, Social Distress, Urban Diversity, Discontinuity, Church-Engaged, External Resource-Seeking, Locally Owned Business-Active, Power Deference, Next Generation Focus, and Self-Reliance. Neighborhood culture subscale scores varied more by geography than by participant's demographics. All subscales predicted one or more health indicator, and some of these relationships were significant after adjusting for participant age and county-level socioeconomic variables. Most of the significant differences on subscales by race/ethnicity were no longer significant after adjusting for participant's age and county-level socioeconomic variables. Most rural/urban and regional differences in culture within the US persisted after these adjustments. Based on correlational analyses, Social Support & Connectedness and Responsibility for Self & Others were the best predictors of participants' overall health and quality of life, and Responsibility for Self & Others was the best predictor (inversely) of the CDC's measures of social vulnerability. Conclusions: Neighborhood culture is measurable, multi-dimensional, distinct from race/ethnicity, and related to health even after controlling for age and socioeconomic factors. The CCS-R is useful for advancing research and practice addressing the complex interactions between individuals, their neighborhood communities, and health outcomes.

Predictors of Adherence to Continuous Positive Airway Pressure in Older Adults With Apnea and Amnestic Mild Cognitive Impairment.

BACKGROUND: Almost 60% of adults with amnestic mild cognitive impairment (aMCI) have obstructive sleep apnea (OSA). Treatment with continuous positive airway pressure (CPAP) may delay cognitive decline, but CPAP adherence is often suboptimal. In this study, we report predictors of CPAP adherence in older adults with aMCI who have increased odds of progressing to dementia, particularly due to Alzheimer's disease. METHODS: The data are from Memories 2, "Changing the Trajectory of Mild Cognitive Impairment with CPAP Treatment of Obstructive Sleep Apnea." Participants had moderate to severe OSA, were CPAP naïve, and received a telehealth CPAP adherence intervention. Linear and logistic regression models examined predictors. RESULTS: The 174 participants (mean age 67.08 years, 80 female, 38 Black persons) had a mean apnea-hypopnea index of 34.78, and 73.6% were adherent, defined as an average of ≥4 hours of CPAP use per night. Only 18 (47.4%) Black persons were CPAP adherent. In linear models, White race, moderate OSA, and participation in the tailored CPAP adherence intervention were significantly associated with higher CPAP use at 3 months. In logistic models, White persons had 9.94 times the odds of adhering to CPAP compared to Black persons. Age, sex, ethnicity, education, body mass index, nighttime sleep duration, daytime sleepiness, and cognitive status were not significant predictors. CONCLUSIONS: Older patients with aMCI have high CPAP adherence, suggesting that age and cognitive impairment should not be a barrier to prescribing CPAP. Research is needed to improve adherence in Black patients, perhaps through culturally tailored interventions.

Quality of Life of Mothers of Infants Subjected to Neonatal Cardiac Surgery: The Importance of Psychosocial Factors.

Background: The World Health Organization acknowledges quality of life (QOL) as subjectively perceived overall well-being by the individual and recognizes it as an essential construct for overall health and wellness. The purpose of this study was to examine the association of infant, environmental, and parental factors with the QOL of mothers of infants at four months post-hospital discharge from cardiac surgery. Methods: Secondary analysis of prospectively collected data from the REACH randomized clinical trial of telehealth home monitoring. The sample included mothers (n = 148) of infants with congenital heart disease who provided data at four months post-discharge. Ten imputations were generated using fully conditional specification methods to address missing data and were combined. All analyses were performed on the imputed data. Mothers' QOL was the main outcome of the analysis, as measured by the Ulm Quality of Life Inventory for Parents. Predictors on QOL were identified based on the World Health Organization QOL framework which recognizes the multidimensional domains influencing QOL that include personal factors, environmental factors, and physical factors related to disease and functioning. Results: The treatment and control groups did not differ on any study variable, thus data were collapsed and analyzed together. Final multivariable model found that the combination of dyadic adjustment, social support, parenting stress, and post-traumatic stress symptoms explained approximately three-quarters of the variance in QOL scores. Conclusions: QOL for mothers of infants with congenital heart disease is largely influenced by psychosocial factors. Future research targeted toward improving maternal QOL should include psychosocial interventions that address social networks and stress.

The Utility of Preoperative HbA1c as a Standardized Protocol in Elective Carpal Tunnel Release: A Retrospective Review of Clinical Outcomes.

Background: In an effort to reduce surgical complications, some institutions have implemented universal hemoglobin A1c (HbA1c) screening for all preoperative patients. However, the value of HbA1c screening for predicting clinically meaningful complications after elective carpal tunnel release (CTR) remains unclear. The purpose of this study was to investigate the clinically meaningful predicative value of HbA1c screening on postoperative complications following elective CTR. Methods: A retrospective cohort study of 790 patients who underwent CTR was performed. All patients had an HbA1c screening performed, regardless of whether they underwent the diagnosis for diabetes or not. Primary outcomes were overall complication rate, rates of major complications (readmission or reoperation), and rates of minor complications (surgical site infection and wound dehiscence). Patients were stratified into 3 groups based on HbA1c: HbA1c <7, HbA1c 7-8, and HbA1c >8. Results: The overall complication rate for all groups was 4.8%. Rates of major complications were 0.4% for readmission and 0.1% for reoperation. For minor complications, the odds ratio (OR) for the HbA1c 7-8 group was 0.6 (95% confidence interval [CI], 0.14-1.77), and for the HbA1c >8 group, the OR was 1.6 (95% CI, 0.66-3.60). All minor complications resolved with outpatient treatment. There were no statistically significant differences between the groups for any comparisons. Conclusions: Elective CTR has a low complication rate. Routine preoperative screening of HbA1c is of little value in predicting clinically meaningful complications.

A comprehensive survey of collaborative biostatistics units in academic health centers.

The organizational structures of collaborative biostatistics units in academic health centers (AHCs) in the United States and their important contributions to research are an evolving and active area of discussion and inquiry. Collaborative biostatistics units may serve as a centralized resource to investigators across various disciplines or as shared infrastructure for investigators within a discipline (e.g., cancer), or a combination of both. The characteristics of such units vary greatly, and there has been no comprehensive review of their organizational structures described in the literature to date. This manuscript summarizes the current infrastructure of such units using responses from 129 leaders. Most leaders were over 45 years old, held doctoral degrees, and were on a 12-month appointment. Over half were tenured or on a tenure track and held primary appointments in a school of medicine. Career advancement metrics most important included being funded as co-investigator on NIH grants and being either first or second author on peer-reviewed publications. Team composition was diverse in terms of expertise and training, and funding sources were typically hybrid. These results provide a benchmark for collaboration models and evaluation and may be used by institutional administrators as they build, evaluate, or restructure current collaborative quantitative support infrastructure.
