Communication between Caregivers of Adults with Cancer and Healthcare Professionals: a Review of Communication Experiences, Associated Factors, Outcomes, and Interventions.

PURPOSE OF REVIEW: Family/unpaid caregivers play an important role in cancer care. This review aims to summarize caregiver communication experiences with healthcare professionals (HCPs). RECENT FINDINGS: The Caregiver-Centered Communication model defines five core functions that HCPs should achieve when interacting with caregivers, including fostering relationships, exchanging information, recognizing and responding to caregiver emotions, aiding in decision making, and assisting in patient care management. The literature shows that caregivers have both positive and negative communication experiences with HCPs with respect to these five core functions. Factors at the caregiver (e.g., demographic characteristics, information sources, caregiving duration, health status), patient (e.g., demographic and clinical characteristics), and HCP levels (e.g., time constraints in clinical settings, communication skills) are associated with caregiver-HCP communication quality. Studies further show that these communication experiences may affect caregiver outcomes, including quality of life, mental health, resilience, and satisfaction with cancer care. Moreover, poor quality caregiver-HCP communication is associated with patient readmission to the hospital and unmet care needs. Interventions for caregivers or patient-caregiver dyads have been shown to enhance caregiver confidence and increase their engagement in communication with HCPs. Interventions for HCPs have shown efficacy in improving their communication skills, particularly in involving caregivers in decision-making discussions. Given time constraints during medical visits, we suggest conducting a caregiver assessment by navigators prior to visits to understand their communication needs. Additionally, reimbursing HCPs for time spent communicating with caregivers during visits could be beneficial. More research is needed to better understand how to enhance caregiver-HCP communication quality.

Mental health outcomes and correlates in cancer patients entering survivorship after curative treatment.

OBJECTIVE: Cancer survivors face numerous physical and mental health challenges after treatment completion. However, few studies have examined mental health in cancer survivors who received curative treatment during the transition out of active treatment and into survivorship. The current study describes the mental health outcomes and their correlates in cancer survivors treated with curative intent during the first year of survivorship. METHODS: A total of 120 cancer survivors of any cancer type completed a survey that assessed depression, anxiety, death ideation, alcohol and substance use, and demographic characteristics. Data regarding cancer type and treatment were extracted from the medical record. RESULTS: Approximately 15% of the sample reported depressive symptoms. Fifteen percent also reported anxiety symptoms in the past two weeks. Ten percent of the sample reported experiencing death ideation since their treatment ended and 7.5% reported death ideation in the past two weeks. Younger age, previous psychiatric diagnosis, and current substance use were associated with depressive symptoms, anxiety symptoms, and death ideation. CONCLUSION: Cancer survivors entering survivorship after curative treatment experience an increased rate of depressive symptoms, anxiety symptoms, and death ideation. Younger cancer survivors and those with previous psychiatric diagnoses or substance use may be at particular risk for mental health problems during the first year of survivorship. Future research within both oncology and primary care should further examine modifiable risk factors for depression, anxiety, and death ideation in cancer survivors at the transition into survivorship after curative treatment to improve survivorship care.

Degree of Bystander-Patient Relationship and Prehospital Care for Opioid Overdose.

BACKGROUND: Across the spectrum of patient care for opioid overdose, an important, yet frequently overlooked feature is the bystander, or witness to the overdose event. For other acute medical events such as cardiac arrest and stroke, research supports that the presence of a bystander is associated with better outcomes. Despite the similarities, however, this well-established conceptual framework has yet to be applied in the context of overdose patient outcomes. The objective of this study was to assess the association between the nature of the bystander-patient relationship and prehospital care measures in patients being treated for opioid overdose. METHODS: A retrospective cohort study was conducted among adults who received naloxone in the prehospital setting for suspected opioid overdose. Patients were identified using a preexisting, longitudinal registry documenting all prehospital administrations of naloxone by first responders in a midsized community. Individuals who received at least one naloxone administration for a suspected opioid overdose between June 1st, 2016 to July 31st, 2018, with available EMS and medical record data were eligible for study inclusion. Bystander type was defined referencing psychology literature and were categorized as: close (spouse/family), proximal (friends), and distal (no relation to patient). The association between bystander type and prehospital patient care measures were estimated using logistic and linear regression models. RESULTS: A total of 602 opioid overdose encounters among 545 patients were identified. Patents tended to be male (67.2%), white (73.6%), and aged 25-44 years (57.1%). Among patients with proximal bystanders present, average time to naloxone administration was 2.4 min less (95% CI = -4.7, -0.2), compared to distal bystanders, after adjusting for covariates. Overdose encounters with 911 dispatch codes more indicative of opioid overdose (i.e., 'overdose/poisoning' vs 'unconscious/fainting') were associated with having a close or proximal bystander present compared to a distal bystander (ORclose vs. distal = 1.8, 95% CI = 1.0, 3.3; ORproximal vs. distal = 3.6, 95% CI = 1.8, 7.1). CONCLUSION: Presence of a proximal bystander during an overdose event is associated with dispatch codes indicative of an overdose and shorter times to naloxone administration compared with those with distal bystanders. These findings offer opportunities for public education and engagement of overdose harm reduction strategies.

Is well-being prior to receiving rehabilitation services associated with postrehabilitation mental health and functioning?

OBJECTIVES: Millions of older adults receive rehabilitation services every year, which aim to restore, maintain, or limit decline in functioning. We examine whether lower reported well-being prior to receiving rehabilitation services is associated with increased odds of worsening anxiety symptoms, depressive symptoms, and impairment in self-care and household activities following rehabilitation. METHODS: Data come from the National Health and Aging Trends Study (NHATS), an annual survey of a nationally representative sample of Medicare beneficiaries aged 65 years and older. Our sample consists of 811 NHATS participants who, in the 2015 interview, had information on well-being and, in the 2016 interview, reported receiving rehabilitation services in the prior year. RESULTS: In multivariable logistic regression analyses, compared to the highest quartile, those in the lowest quartile of well-being at baseline have increased odds of having worsening depressive symptoms (OR = 9.25, 95% CI: 3.78-22.63) and worsening impairments in self-care activities (OR = 2.39, 95% CI: 1.12-5.11). CONCLUSION: Our findings suggest that older adults with the lowest levels of baseline well-being may be susceptible to having worsening depressive symptoms and impairment in self-care activities following rehabilitation services. Examination on whether consideration of well-being during the rehabilitation process could lead to better mental health and functional outcomes following rehabilitation is needed.

Association of the cumulative burden of late-life anxiety and depressive symptoms with functional impairment.

OBJECTIVES: This study investigates the association of the cumulative burden of anxiety-only, depression-only, and comorbid anxiety and depression symptoms with (a) incident self-care or household activities impairment among those with no baseline self-care or household activities impairment, respectively, or (b) change in status of self-care or household activities impairment among those with baseline impairment. METHODS: This study consists of participants (N = 4619) from the National Health and Aging Trends Study, a longitudinal study that examines a nationally representative sample of US adults aged 65 years and older. Outcomes included incident or change in self-care or household activity impairment. Primary independent variables were yearly counts of screening positive for clinically significant symptoms for anxiety-only, depression-only, or co-occurring anxiety and depression. Multivariable logistic regression models examined incident impairment and change in impairment status. RESULTS: Yearly counts of anxiety-only symptoms were associated with incident impairment in self-care and household activities and less improvement in self-care functioning. Yearly counts of depression-only symptoms were associated with incident impairment in self-care and household activities. Yearly counts of co-occurring symptoms of anxiety and depression were associated with incident impairment in self-care and household activities, less improvement in self-care activities, and worsening impairment in household activities. CONCLUSIONS: This study finds that the cumulative burden of co-occurring anxiety and depression symptoms is associated with incident impairment in functioning, persistent self-care impairment, and deterioration in household activity impairment. These findings emphasize the importance of managing late-life anxiety and depressive symptoms, which are treatable, frequently co-occur, and contribute to disability.

The association of a heart attack or stroke with depressive symptoms stratified by the presence of a close social contact: findings from the National Health and Aging Trends Study Cohort.

OBJECTIVE: The objective of the study is to examine whether the risk of having clinically significant depressive symptoms following a heart attack or stroke varies by the presence of a close social contact. METHODS: The National Health and Aging Trends Study is a nationally representative longitudinal survey of US Medicare beneficiaries aged 65 and older initiated in 2011. A total of 5643 older adults had information on social contacts at baseline and depressive symptoms at the 1-year follow-up interview. The two-item Patient Health Questionnaire identified clinically significant depressive symptoms. Interview questions examined social contacts and the presence of self-reported heart attack or stroke during the year of follow-up. RESULTS: A total of 297 older adults reported experiencing a heart attack and/or stroke between their baseline and follow-up interviews. In regression analyses accounting for sociodemographics, baseline depressive symptoms, medical comorbidity, and activities of daily living impairment, older adults with no close social contacts had increased odds of depressive symptoms at follow-up after experiencing a heart attack or stroke, while those with close social contacts had increased odds of depressive symptoms at follow-up after experiencing a stroke, but not a heart attack. CONCLUSIONS: Older adults have increased odds of having depressive symptoms following a self-reported stroke, but only those with no close social contacts had increased odds of depressive symptoms following a heart attack. Social networks may play a role in the mechanisms underlying depression among older adults experiencing certain acute health events. Future work exploring the potential causal relationships suggested here, if confirmed, could inform interventions to alleviate or prevent depression among at risk older adults.

A Quiescent Phase in Human Mortality? Exploring the Ages of Least Vulnerability.

Demographic studies of mortality often emphasize the two ends of the lifespan, focusing on the declining hazard after birth or the increasing risk of death at older ages. We call attention to the intervening phase, when humans are least vulnerable to the force of mortality, and consider its features in both evolutionary and historical perspectives. We define this quiescent phase (Q-phase) formally, estimate its bounds using life tables for Swedish cohorts born between 1800 and 1920, and describe changes in the morphology of the Q-phase. We show that for cohorts aging during Sweden's demographic and epidemiological transitions, the Q-phase became longer and more pronounced, reflecting the retreat of infections and maternal mortality as key causes of death. These changes revealed an underlying hazard trajectory that remains relatively low and constant during the prime ages for reproduction and investment in both personal capital and relationships with others. Our characterization of the Q-phase highlights it as a unique, dynamic, and historically contingent cohort feature, whose increased visibility was made possible by the rapid pace of survival improvements in the nineteenth and twentieth centuries. This visibility may be reduced or sustained under subsequent demographic regimes.

Home but still engaged: participation in social activities among the homebound.

PURPOSE: Participation in social and community activities that require leaving one's home is important to older adults; however, many older adults have difficulty or are unable to leave their dwellings, and little is known from national samples about issues related to remaining active outside the home or the barriers faced by these older adults. DESIGN AND METHODS: We used the National Health and Aging Trends Study, a nationally representative study of older adults (n = 7197), to understand the following: (1) the importance that homebound and semi-homebound adults place on involvement in social or community activities, (2) their current level of involvement, and (3) reported barriers to participation. RESULTS: Despite the heavy burden of functional limitations, depression, pain, and falls, homebound adults reported that activities outside the home were important to them ranging from 25.2 % (attend clubs) to 70.0 % (visit family). Similarly, semi-homebound older adults had a strong interest in such participation, including visiting friends and family (81.8 %), attending religious services (72.6 %), and going out for enjoyment (72.5 %). Many homebound adults reported health (42.9-64.1 % depending on the activity) and transportation (12.2-18.2 %) as barriers to participation. Semi-homebound adults also identified health (23.8-41.0 %) and transportation (6.5-10.2 %) as participation barriers. IMPLICATIONS: This information can be useful in designing community programs that will foster meaningful social and community engagement for older adults, which may improve their quality of life.

Prehospital Trauma Triage Decision-making: A Model of What Happens between the 9-1-1 Call and the Hospital.

We describe the decision-making process used by emergency medical services (EMS) providers in order to understand how 1) injured patients are evaluated in the prehospital setting; 2) field triage criteria are applied in-practice; and 3) selection of a destination hospital is determined. We conducted separate focus groups with advanced and basic life support providers from rural and urban/suburban regions. Four exploratory focus groups were conducted to identify overarching themes and five additional confirmatory focus groups were conducted to verify initial focus group findings and provide additional detail regarding trauma triage decision-making and application of field triage criteria. All focus groups were conducted by a public health researcher with formal training in qualitative research. A standardized question guide was used to facilitate discussion at all focus groups. All focus groups were audio-recorded and transcribed. Responses were coded and categorized into larger domains to describe how EMS providers approach trauma triage and apply the Field Triage Decision Scheme. We conducted 9 focus groups with 50 EMS providers. Participants highlighted that trauma triage is complex and there is often limited time to make destination decisions. Four overarching domains were identified within the context of trauma triage decision-making: 1) initial assessment; 2) importance of speed versus accuracy; 3) usability of current field triage criteria; and 4) consideration of patient and emergency care system-level factors. Field triage is a complex decision-making process which involves consideration of many patient and system-level factors. The decision model presented in this study suggests that EMS providers place significant emphasis on speed of decisions, relying on initial impressions and immediately observable information, rather than precise measurement of vital signs or systematic application of field triage criteria.

Ventilation during COVID-19 in a school for students with intellectual and developmental disabilities (IDD).

BACKGROUND: This study examined the correlation of classroom ventilation (air exchanges per hour (ACH)) and exposure to CO2 ≥1,000 ppm with the incidence of SARS-CoV-2 over a 20-month period in a specialized school for students with intellectual and developmental disabilities (IDD). These students were at a higher risk of respiratory infection from SARS-CoV-2 due to challenges in tolerating mitigation measures (e.g. masking). One in-school measure proposed to help mitigate the risk of SARS-CoV-2 infection in schools is increased ventilation. METHODS: We established a community-engaged research partnership between the University of Rochester and the Mary Cariola Center school for students with IDD. Ambient CO2 levels were measured in 100 school rooms, and air changes per hour (ACH) were calculated. The number of SARS-CoV-2 cases for each room was collected over 20 months. RESULTS: 97% of rooms had an estimated ACH ≤4.0, with 7% having CO2 levels ≥2,000 ppm for up to 3 hours per school day. A statistically significant correlation was found between the time that a room had CO2 levels ≥1,000 ppm and SARS-CoV-2 PCR tests normalized to room occupancy, accounting for 43% of the variance. No statistically significant correlation was found for room ACH and per-room SARS-CoV-2 cases. Rooms with ventilation systems using MERV-13 filters had lower SARS-CoV-2-positive PCR counts. These findings led to ongoing efforts to upgrade the ventilation systems in this community-engaged research project. CONCLUSIONS: There was a statistically significant correlation between the total time of room CO2 concentrations ≥1,000 and SARS-CoV-2 cases in an IDD school. Merv-13 filters appear to decrease the incidence of SARS-CoV-2 infection. This research partnership identified areas for improving in-school ventilation.

Multisystem physiological dysfunction is associated with depressive symptoms in a population-based sample of older adults.

OBJECTIVE: To evaluate the association between multisystem physiological dysfunction and depressive symptom severity in the US older adults. METHODS: We examined 2405 adults of age 60 years and older by using the data from the 2005-2008 National Health and Nutrition Examination Survey. We constructed a summary score of "physiological dysfunction," encompassing cardiovascular function, glucose regulation, liver function, and renal function. Overall depressive symptoms were obtained from the 9-item Patient Health Questionnaire depression scale, and factor analysis was used to derive affective and somatic symptom scores. We employed multiple linear regression models to estimate associations between physiological dysfunction scores and affective, somatic, and overall depressive symptoms, while adjusting for demographic, socioeconomic factors, and other potentially confounding factors. RESULTS: Greater multisystem physiological dysfunction scores were associated with an increased severity of overall, affective, and somatic depressive symptoms. These associations persisted after adjusting for all covariates: beta = 0.23 (95% confidence interval (CI) = 0.13, 0.32); beta = 0.08 (95% CI = 0.04, 0.11); beta = 0.12 (95% CI = 0.06, 0.18), respectively. CONCLUSIONS: Our results suggest that the multisystem physiological dysfunction is associated with late-life depressive symptoms. Additional longitudinal studies of links between allostatic load, psychosocial stress events throughout the life course, and late-life depressive symptoms may shed further light on this association.

History of S. aureus Skin Infection Significantly Associates with History of Eczema Herpeticum in Patients with Atopic Dermatitis.

INTRODUCTION: Patients with atopic dermatitis (AD) are uniquely susceptible to a number of serious viral skin complications, including eczema herpeticum (EH), caused by herpes simplex virus. This study explored the associations between biomarkers of epithelial barrier dysfunction, type 2 immunity, Staphylococcus aureus infection, and S. aureus-specific immunoglobulin responses in a cohort of AD subjects with and without a history of EH (EH+ and EH-, respectively). METHODS: A total of 112 subjects with AD (56 EH+, 56 EH-), matched by age and AD severity, were selected from a registry of over 3000 AD subjects. Logistic regression was used to test the association between history of S. aureus skin infection and history of EH, while controlling for a number of confounders. RESULTS: Compared to those without a history of S. aureus skin infection, subjects with a history of S. aureus skin infection were found to have more than sixfold increased odds of having a history of EH (6.60, 95% confidence interval [CI]: 2.00-21.83), after adjusting for history of other viral skin infections (molluscum contagiosum virus, human papillomavirus), serum total IgE, and IgG against the S. aureus virulence factor SElX. CONCLUSIONS: These findings indicate an important relationship between S. aureus skin infections and EH.

Association of Radiation Dose to the Amygdala-Orbitofrontal Network with Emotion Recognition Task Performance in Patients with Low-Grade and Benign Brain Tumors.

BACKGROUND: Although data are limited, difficulty in social cognition occurs in up to 83% of patients with brain tumors. It is unknown whether cranial radiation therapy (RT) dose to the amygdala-orbitofrontal network can impact social cognition. METHODS: We prospectively enrolled 51 patients with low-grade and benign brain tumors planned for cranial RT. We assessed longitudinal changes on an emotion recognition task (ERT) that measures the ability to recognize emotional states by displaying faces expressing six basic emotions and their association with the RT dose to the amygdala-orbitofrontal network. ERT outcomes included the median time to choose a response (ERTOMDRT) or correct response (ERTOMDCRT) and total correct responses (ERTHH). RESULTS: The RT dose to the amygdala-orbitofrontal network was significantly associated with longer median response times on the ERT. Increases in median response times occurred at lower doses than decreases in total correct responses. The medial orbitofrontal cortex was the most important variable on regression trees predicting change in the ERTOMDCRT. DISCUSSION: This is, to our knowledge, the first study to show that off-target RT dose to the amygdala-orbitofrontal network is associated with performance on a social cognition task, a facet of cognition that has previously not been mechanistically studied after cranial RT.

Modifiable fall risk factors among older adults with advanced cancer: Secondary analysis of a cluster-randomized clinical trial.

INTRODUCTION: Older adults with cancer have unique fall risk factors related to their disease and treatment such as polypharmacy and neurotoxic treatments. In this secondary analysis, we identified modifiable risk factors associated with future falls among older adults with advanced cancers. MATERIALS AND METHODS: Data were from the COACH study (ClinicalTrials.gov: NCT02107443; PI: Mohile). Patients were age ≥ 70, had stage III/IV solid tumor or lymphoma, ≥1 geriatric assessment impairment, and were receiving palliative intent treatment. Falls were self-reported at baseline (in the past six months), four to six weeks, three months, and six months. We generated inverse probability weights to account for mortality-related loss to follow-up and applied these in generalized linear mixed models to estimate incidence rate ratios. RESULTS: Of 541 patients (mean age: 77, standard deviation [SD]: 5.27), 140 (26%) reported prior falls at baseline, and 467 (86%) had falls data for ≥1 follow-up timepoint. Of those, 103 (22%) reported at least one fall during the follow-up period, and 112 (24%) had incomplete follow-up due to death. In fully adjusted models, prior falls and impaired Timed Up and Go score were associated with higher incidence of falls over 6 months. DISCUSSION: We identified several potentially modifiable fall risk factors in older adults with advanced cancers. Future studies should consider ways to integrate fall risk assessment into ongoing cancer care and intervene to reduce falls in this population.

A statistically significant correlation was found between the time that a room had CO2 levels ≥1,000 ppm and SARS-CoV-2 PCR tests normalized to room occupancy, accounting for 43% of the variance. No statistically significant correlation was found for room ACH and per-room SARS-CoV-2 cases. Rooms with ventilation systems using MERV-13 filters had lower SARS-CoV-2-positive PCR counts. These findings led to ongoing efforts to upgrade the ventilation systems in this community-engaged research project. Conclusions: There was a statistically significant correlation between the total time of room CO2 concentrations ≥1,000 and SARS-CoV-2 cases in an IDD school. Merv-13 filters appear to decrease the incidence of SARS-CoV-2 infection. This research partnership identified areas for improving in-school ventilation.

Patterns of 12-year change in physical activity levels in community-dwelling older women: can modest levels of physical activity help older women live longer?

Few studies have addressed changes in physical activity participation over time among the elderly. The authors hypothesized that there were distinct trajectories of physical activity level over time and identifiable predictors of such trajectories, as well as that the maintenance of regular physical activity, even below recommended levels, was associated with lower mortality risk. Using longitudinal data (1994-2009) from 433 initially high-functioning older women aged 70-79 years at baseline, a joint latent class and survival mixture model identified 4 activity trajectory classes: always active (16.6%), fast declining (19.2%), stable moderate (32.3%), and always sedentary (31.9%). Obesity, coronary artery disease, chronic obstructive pulmonary disease, depressive symptoms, low self-efficacy, mobility disability, and low energy were associated with sedentary behavior and/or a fast decline in activity. Women in the fast declining and always sedentary classes had hazard ratios for death of 2.34 (95% confidence interval: 1.20, 4.59) and 3.34 (95% confidence interval: 1.72, 6.47), respectively, compared with the always active class; no mortality difference was found between the stable moderate and always active groups (hazard ratio = 1.24, 95% confidence interval: 0.63, 2.47). Our findings suggest that physical activity does not have to be vigorous to be beneficial and that the gain may be the greatest among women who reported the lowest levels of activity.

Physiologic dysfunction scores and cognitive function test performance in U.S. adults.

OBJECTIVE: To investigate the relationship between a measure of cumulative physiologic dysfunction and specific domains of cognitive function. METHODS: We examined a summary score measuring physiologic dysfunction, a multisystem measure of the body's ability to effectively adapt to physical and psychological demands, in relation to cognitive function deficits in a population of 4511 adults aged 20 to 59 who participated in the Third National Health and Nutrition Examination Survey (1988-1994). Measures of cognitive function comprised three domains: working memory, visuomotor speed, and perceptual-motor speed. "Physiologic dysfunction" scores summarizing measures of cardiovascular, immunologic, kidney, and liver functions were explored. We used multiple linear regression models to estimate associations between cognitive function measures and physiologic dysfunction scores, adjusting for socioeconomic factors, test conditions, and self-reported health factors. RESULTS: We noted a dose-response relationship between physiologic dysfunction and working memory (coefficient = 0.207, 95% confidence interval = 0.066-0.348, p < .0001), which persisted after adjustment for all covariates (p = .03). We did not observe any significant relationships between dysfunction scores and visuomotor (p = .37) or perceptual-motor ability (p = .33). CONCLUSIONS: Our findings suggest that multisystem physiologic dysfunction is associated with working memory. Future longitudinal studies are needed to clarify the underlying mechanisms and explore the persistency of this association into later life. We suggest that such studies should incorporate physiologic data, neuroendocrine parameters, and a wide range of specific cognitive domains.

Preterm prelabor rupture of membranes: evaluating latency and neonatal morbidity for pregnancies with expectant management ≥34 weeks.

OBJECTIVE: To evaluate the association between latency and neonatal morbidity for pregnancies with expectant management of PPROM ≥34 w. MATERIALS AND METHODS: A retrospective cohort of singletons with PPROM from 2011 to 2016. Exposure was defined as latency (period from diagnosis of PPROM to delivery) and was analyzed as a count variable (i.e. number of days) and binary variable (≥7 days and <7 days; ≥21 days and <21 days). Primary outcome was composite neonatal morbidity defined as need for respiratory support, culture positive neonatal sepsis, and/or neonatal antibiotics >72 h. Fisher's exact test, chi-square test, Mann-Whitney U and binary logistic regression tests were performed with p<.05 considered significant. RESULTS: Of 813 pregnancies, 104 met inclusion criteria: 73 (70.2%) pregnancies with PPROM diagnosed at <34 weeks and 31 (29.8%) pregnancies with PPROM diagnosed ≥34 weeks. A total of 58 (55.8%) pregnancies had a latency of ≥7 days and 46 (44.2%) had a latency <7 days. There was no difference in composite neonatal morbidity for latency ≥7 d versus <7 d (aOR 0.92; 95% CI 0.30-2.82) or latency as a count variable (aOR 0.70; 95% CI 0.23-2.13). However, a latency ≥21 d was associated with increased composite neonatal morbidity (aOR 10.24, 95% CI 1.42-73.99). CONCLUSION: In pregnancies with PPROM expectantly managed ≥34 w, a latency of ≥7 d is not associated with significant differences in neonatal morbidity. However, different latency thresholds may be more clinically relevant for late preterm pregnancies. The increase in composite neonatal morbidity associated with a latency >21 days should be an area of future investigation and may suggest there is a population of pregnancies with PPROM which may not benefit from expectant management past 34 weeks.

Breastfeeding Motivation Predicts Infant Feeding Intention and Outcomes: Evaluation of a Novel Adaptation of the Treatment Self-Regulation Questionnaire.

BACKGROUND: Identifying those at risk for suboptimal breastfeeding outcomes remains critical for improving maternal and child health. Prenatal breastfeeding motivation may be a key predictor useful for identifying those who would benefit from additional breastfeeding support. RESEARCH AIMS: To (1) validate a breastfeeding-specific adaptation of the Treatment Self-Regulation Questionnaire (TSRQ-BF); and (2) determine if breastfeeding motivation predicts prenatal breastfeeding intentions and early breastfeeding outcomes. METHODS: Participants in their third trimester of pregnancy (N = 150) completed several instruments, including the TSRQ-BF and infant feeding intention, and could opt to participate in an assessment of early breastfeeding outcomes (by medical record review). TSRQ-BF subscales were derived from factor analysis, and multivariable regression was used to evaluate the association between TSRQ-BF subscale scores and breastfeeding intention and outcomes during the birth hospitalization. RESULTS: Autonomous (related to personal values/beliefs regarding self) and Autonomous-Baby (values/benefits for the infant) subscale scores were positively associated with intended exclusivity (aOR [95% CI]: 2.22 [1.57, 3.30], 4.94 [2.49, 11.07], respectively) while higher scores on these subscales predicted longer time to planned cessation (aHR [95% CI]: 0.72 [0.61, 0.84],0.52 [0.34, 0.81]). Higher Amotivation (lack of motivation) scores were negatively associated with intended exclusivity (0.45 [0.26, 0.74]). Higher scores on Autonomous, Autonomous-Baby, and Controlled (avoidance of negative feelings/punishment or gaining reward) subscales were associated with greater odds of hospital exclusivity (aOR [95% CI]: 3.39 [1.75, 8.00], 3.44 [1.66, 9.04] and 6.05 [1.88, 29.04]) and lower odds of 2-day formula supplementation (aOR [95% CI]: 0.31 [0.14, 0.59],0.28 [0.11, 0.59], 0.19 [0.04, 0.62]). CONCLUSIONS: The TSRQ-BF predicted breastfeeding intent and outcomes, and may be helpful for identifying patients at risk for suboptimal breastfeeding outcomes before delivery.

Assessment of absolute risk of life-threatening cardiac events in long QT syndrome patients.

Background: Risk stratification in long QT syndrome (LQTS) patients is important for optimizing patient care and informing clinical decision making. We developed a risk prediction algorithm with prediction of 5-year absolute risk of the first life-threatening arrhythmic event [defined as aborted cardiac arrest, sudden cardiac death, or appropriate implantable cardioverter defibrillator (ICD) shock] in LQTS patients, accounting for individual risk factors and their changes over time. Methods: Rochester-based LQTS Registry included the phenotypic cohort consisting of 1,509 LQTS patients with a QTc ≥ 470 ms, and the genotypic cohort including 1,288 patients with single LQT1, LQT2, or LQT3 mutation. We developed two separate risk prediction models which included pre-specified time-dependent covariates of beta-blocker use, syncope (never, syncope while off beta blockers, and syncope while on beta blockers), and sex by age < and ≥13 years, baseline QTc, and genotype (for the genotypic cohort only). Follow-up started from enrollment in the registry and was censored at patients' 50s birthday, date of death due to reasons other than sudden cardiac death, or last contact, whichever occurred first. The predictive models were externally validated in an independent cohort of 1,481 LQTS patients from Pavia, Italy. Results: In Rochester dataset, there were 77 endpoints in the phenotypic cohort during a median follow-up of 9.0 years, and 47 endpoints in the genotypic cohort during a median follow-up of 9.8 years. The time-dependent extension of Harrell's generalized C-statistics for the phenotypic model and genotypic model were 0.784 (95% CI: 0.740-0.827) and 0.785 (95% CI: 0.721-0.849), respectively, in the Rochester cohort. The C-statistics obtained from external validation in the Pavia cohort were 0.700 (95% CI: 0.610-0.790) and 0.711 (95% CI: 0.631-0.792) for the two models, respectively. Based on the above models, an online risk calculator estimating a 5-year risk of life-threatening arrhythmic events was developed. Conclusion: This study developed two risk prediction algorithms for phenotype and genotype positive LQTS patients separately. The estimated 5-year absolute risk can be used to quantify a LQTS patient's risk of developing life-threatening arrhythmic events and thus assisting in clinical decision making regarding prophylactic ICD therapy.
