A lineage perspective on hominin taxonomy and evolution.

An uncritical reliance on the phylogenetic species concept has led paleoanthropologists to become increasingly typological in their delimitation of new species in the hominin fossil record. As a practical matter, this approach identifies species as diagnosably distinct groups of fossils that share a unique suite of morphological characters but, ontologically, a species is a metapopulation lineage segment that extends from initial divergence to eventual extinction or subsequent speciation. Working from first principles of species concept theory, it is clear that a reliance on morphological diagnosabilty will systematically overestimate species diversity in the fossil record; because morphology can evolve within a lineage segment, it follows that early and late populations of the same species can be diagnosably distinct from each other. We suggest that a combination of morphology and chronology provides a more robust test of the single-species null hypothesis than morphology alone.

Machine learning for understanding and predicting neurodevelopmental outcomes in premature infants: a systematic review.

BACKGROUND: Machine learning has been attracting increasing attention for use in healthcare applications, including neonatal medicine. One application for this tool is in understanding and predicting neurodevelopmental outcomes in preterm infants. In this study, we have carried out a systematic review to identify findings and challenges to date. METHODS: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Four databases were searched in February 2022, with articles then screened in a non-blinded manner by two authors. RESULTS: The literature search returned 278 studies, with 11 meeting the eligibility criteria for inclusion. Convolutional neural networks were the most common machine learning approach, with most studies seeking to predict neurodevelopmental outcomes from images and connectomes describing brain structure and function. Studies to date also sought to identify features predictive of outcomes; however, results varied greatly. CONCLUSIONS: Initial studies in this field have achieved promising results; however, many machine learning techniques remain to be explored, and the consensus is yet to be reached on which clinical and brain features are most predictive of neurodevelopmental outcomes. IMPACT: This systematic review looks at the question of whether machine learning can be used to predict and understand neurodevelopmental outcomes in preterm infants. Our review finds that promising initial works have been conducted in this field, but many challenges and opportunities remain. Quality assessment of relevant articles is conducted using the Newcastle-Ottawa Scale. This work identifies challenges that remain and suggests several key directions for future research. To the best of the authors' knowledge, this is the first systematic review to explore this topic.

Examining ACCURE's Nurse Navigation Through an Antiracist Lens: Transparency and Accountability in Cancer Care.

There are persistent disparities in the delivery of cancer treatment, with Black patients receiving fewer of the recommended cancer treatment cycles than their White counterparts on average. To enhance racial equity in cancer care, innovative methods that apply antiracist principles to health promotion interventions are needed. The parent study for the current analysis, the Accountability for Cancer Care through Undoing Racism and Equity (ACCURE) intervention, was a system-change intervention that successfully eliminated the Black-White disparity in cancer treatment completion among patients with early-stage breast and lung cancer. The intervention included specially trained nurse navigators who leveraged real-time data to follow-up with patients during their treatment journeys. Community and academic research partners conducted thematic analysis on all clinical notes (n = 3,251) written by ACCURE navigators after each contact with patients in the specialized navigation arm (n = 162). Analysis was informed by transparency and accountability, principles adapted from the antiracist resource Undoing Racism and determined as barriers to treatment completion through prior research that informed ACCURE. We identified six themes in the navigator notes that demonstrated enhanced accountability of the care system to patient needs. Underlying these themes was a process of enhanced data transparency that allowed navigators to provide tailored patient support. Themes include (1) patient-centered advocacy, (2) addressing system barriers to care, (3) connection to resources, (4) re-engaging patients after lapsed treatment, (5) addressing symptoms and side effects, and (6) emotional support. Future interventions should incorporate transparency and accountability mechanisms and examine the impact on racial equity in cancer care.

African American Women's Experiences with Birth After a Prior Cesarean Section.

OBJECTIVES: Women who have had a cesarean section (C-section) and become pregnant again may choose to have a planned repeat cesarean delivery (RCD) or vaginal birth after a cesarean (VBAC). This study aimed to characterize the pregnancy and birth experiences of African American (AA) women who had a successful VBAC, failed VBAC, or RCD. METHODS: Eligible participants (N = 25) self-identified as AA, had a C-section and a subsequent birth(s) in the past 12 years, and were educated past high school. Each participant was individually interviewed via phone call. The Sort and Sift, Think and Shift method was used to evaluate interview transcripts to minimize researcher bias and emphasize the voices of the participants. RESULTS: The resulting themes included the impact of providers on pregnancy and childbirth satisfaction, the value of autonomy in maternal health decision-making, and the role that racism plays in AA women's birth experiences. Although some participants recalled a positive experience, the presence of limited autonomy, lack of support, and negative experiences with providers indicate that birth after a prior C-section for AA women can be improved. CONCLUSIONS: Providers should address their own racial biases and utilize the shared decision-making approach when their patients decide between a VBAC and RCD to improve patient satisfaction.

Hepatomegaly and short stature in a 14-year-old with type 1 diabetes mellitus: case report.

BACKGROUND: Mauriac syndrome is a rare consequence of poorly controlled insulin-dependent diabetes, characterized by hepatomegaly, growth failure, delayed onset of puberty, and cushingoid features. Case reports of patients with Mauriac syndrome are found infrequently in the literature given historic improvements in diabetes management due to readily available insulin therapy. METHODS: We describe a case of a 14-year-old girl who presented with acute onset abdominal pain, distention, and orthopnea. RESULTS: She had a history of poorly controlled insulin-dependent diabetes as well as short stature. Abdominal imaging revealed impressive hepatomegaly. Laboratory testing showed markedly elevated triglycerides and cholesterol. Mauriac syndrome was suspected and diagnosed by liver biopsy, which demonstrated significant glycogenic hepatopathy. CONCLUSIONS: This case provides an illustrative example of Mauriac syndrome in a child who did not experience delayed onset of puberty and continued to have regular menses unlike what has been previously described. Furthermore, this case highlights the important consideration for significant dyslipidemia in patients with Mauriac syndrome and discusses the challenges of controlling insulin-dependent diabetes in the adolescent population.

'It's like you don't have a roadmap really': using an antiracism framework to analyze patients' encounters in the cancer system.

Background: Cancer patients can experience healthcare system-related challenges during the course of their treatment. Yet, little is known about how these challenges might affect the quality and completion of cancer treatment for all patients, and particularly for patients of color. Accountability for Cancer Care through Undoing Racism and Equity is a multi-component, community-based participatory research intervention to reduce Black-White cancer care disparities. This formative work aimed to understand patients' cancer center experiences, explore racial differences in experiences, and inform systems-level interventions.Methods: Twenty-seven breast and lung cancer patients at two cancer centers participated in focus groups, grouped by race and cancer type. Participants were asked about what they found empowering and disempowering regarding their cancer care experiences. The community-guided analysis used a racial equity approach to identify racial differences in care experiences.Results: For Black and White patients, fear, uncertainty, and incomplete knowledge were disempowering; trust in providers and a sense of control were empowering. Although participants denied differential treatment due to race, analysis revealed implicit Black-White differences in care.Conclusions: Most of the challenges participants faced were related to lack of transparency, such that improvements in communication, particularly two-way communication could greatly improve patients' interaction with the system. Pathways for accountability can also be built into a system that allows patients to find solutions for their problems with the system itself. Participants' insights suggest the need for patient-centered, systems-level interventions to improve care experiences and reduce disparities.

The role of patient-physician relationship on health-related quality of life and pain in cancer patients.

PURPOSE: Health-related quality of life (HRQOL) and pain are important supportive cancer care outcomes. The patient-provider relationship, a modifiable care experience, has been linked to healthcare outcomes; however, less is known about associations between patient-provider relationship and supportive care outcomes in cancer patients. We examined the role of multiple aspects of the patient-provider relationship in explaining patterns of HRQOL and pain among breast and lung cancer patients. METHODS: Our analysis included 283 breast and lung cancer patients from two cancer centers. Clinical data and survey data on patient sociodemographic factors, physical and mental HRQOL, pain, and patient-physician relationship (i.e., doctor's respectfulness, time spent with doctors, patient involvement in decision-making, satisfaction with care, and following doctor's advice/treatment plan) were collected at baseline and during treatment. We estimated adjusted modified Poisson regression models to assess associations between patient-physician relationship factors and physical and mental HRQOL and pain. RESULTS: Compared with patients reporting suboptimal respect from doctors, patients reporting optimal respect were less likely to report below average physical HRQOL (adjusted risk ratio (ARR), 0.73; 95%CI, 0.62-0.86), below average mental HRQOL (ARR, 0.71; 95%CI, 0.54-0.93), and moderate-to-severe pain (ARR, 0.53; 95%CI, 0.35-0.79). Patients reporting optimal involvement in care decision-making and patients who reported following their doctor's advice/treatment plan were less likely to report below average mental HRQOL than their respective counterparts (ARR, 0.64; 95%CI, 0.50-0.83; ARR, 0.65; 95%CI, 0.48-0.86). CONCLUSION: Multiple patient-physician relationship factors account for variations in HRQOL and pain in cancer patients. These findings provide insight into potential targets for improving the patient-provider relationship and supportive cancer care outcomes.

Racial Differences in the Influence of Health Care System Factors on Informal Support for Cancer Care Among Black and White Breast and Lung Cancer Survivors.

This retrospective, secondary qualitative analysis investigates whether health system factors influence social support among Black and white breast and lung cancer survivors and racial differences in support. These data come from race- and cancer-stratified focus groups (n = 6) and interviews (n = 2) to inform a randomized controlled trial utilizing antiracism and community-based participatory research approaches. Findings indicate social support was helpful for overcoming treatment-related challenges, including symptom management and patient-provider communication; racial differences in support needs and provision were noted. Resources within individual support networks reflect broader sociostructural factors. Reliance on family/friends to fill gaps in cancer care may exacerbate racial disparities.

Racial differences in symptom management experiences during breast cancer treatment.

PURPOSE: Racial disparities in cancer treatment-related symptom burden are well documented and linked to worse treatment outcomes. Yet, little is known about racial differences in patients' treatment-related symptom management experiences. Such understanding can help identify modifiable drivers of symptom burden inequities. As part of the Cancer Health Accountability for Managing Pain and Symptoms (CHAMPS) study, we examined racial differences in symptom management experiences among Black and White breast cancer survivors (BCS). METHODS: We conducted six focus groups (n = 3 Black BCS groups; n = 3 White BCS groups) with 22 stages I-IV BCS at two cancer centers. Focus groups were audio-recorded and transcribed verbatim. Based on key community-based participatory research principles, our community/academic/medical partner team facilitated focus groups and conducted qualitative analyses. RESULTS: All BCS described positive symptom management experiences, including clinician attentiveness to symptom concerns and clinician recommendations for pre-emptively managing symptoms. Black BCS commonly reported having to advocate for themselves to get information about treatment-related symptoms, and indicated dissatisfaction regarding clinicians' failure to disclose potential treatment-related symptoms or provide medications to address symptoms. White BCS often described dissatisfaction regarding inadequate information on symptom origins and clinicians' failure to offer reassurance. CONCLUSIONS: This study elucidates opportunities for future research aimed at improving equity for cancer treatment-related symptom management. For Black women, warnings about anticipated symptoms and treatment for ongoing symptoms were particular areas of concern. Routine symptom assessment for all women, as well as clinicians' management of symptoms for racially diverse cancer patients, need to be more thoroughly studied and addressed.

Effects of etomidate on adrenal suppression: a review of intubated septic patients.

BACKGROUND: Etomidate is a commonly used sedative during rapid sequence intubation (RSI). Septic patients are at an increased risk of independently developing adrenal suppression, which has been associated with increased mortality in some studies. Since etomidate affects cortisol production, its use in septic patients is controversial. However, data are still lacking to prove that etomidate should be avoided in this patient population. OBJECTIVES: The objective was to review patients diagnosed with sepsis who received etomidate during RSI. Our hypothesis is that patients who receive etomidate will experience clinically significant hypotension within the first 24 hours of intubation. METHODS: A retrospective cohort study was conducted on patients intubated in the emergency department (ED) and medical/surgical floors at our institution from 2004 to 2010. Once patients with a diagnosis of sepsis were identified, it was determined whether the patients received etomidate or a different sedative during intubation. The primary endpoint was clinically significant hypotension: systolic blood pressure <90 mm Hg or mean arterial pressure <60 mm Hg. RESULTS: One hundred fifty-seven patients, 110 etomidate and 47 non-etomidate, were included in the final analysis. Hypotension was seen in 79 (71.8%) patients who received etomidate and in 14 (29.8%) patients who received another sedative (P ≤ .001). There were no statistically significant differences in secondary objectives. CONCLUSION: Etomidate use for induction of anesthesia during RSI was associated with clinically significant hypotension when compared to other sedatives. The hypotension was transient and did not translate into statistically significant differences in the secondary clinical endpoints.

Brief communication: beyond the South African cave paradigm--Australopithecus africanus from Plio-Pleistocene paleosol deposits at Taung.

Following the discovery of the "Taung Child" (Australopithecus africanus) in 1924 in the Buxton-Norlim Limeworks near Taung, the fossil-bearing deposits associated with the Dart and Hrdlicka pinnacles have been interpreted as the mined remnants of cave sediments that formed within the Plio-Pleistocene Thabaseek Tufa: either as a younger cave-fill or as contemporaneous carapace caves. When combined with the Plio-Pleistocene dolomitic cave deposits from the "Cradle of Humankind," a rather restricted view emerges that South African early hominins derived from cave deposits, whereas those of east and central Africa are derived from fluvio-lacustrine and paleosol deposits. We undertook a sedimentological and paleomagnetic analysis of the pink-colored deposit (PCS) from which the "Taung Child" is purported to have derived and demonstrate that it is a calcrete, a carbonate-rich pedogenic sediment, which formed on the paleo-land surface. The deposit extends 100 s of meters laterally beyond the Dart and Hrdlicka Pinnacles where it is interbedded with the Thabaseek Tufa, indicating multiple episodes of calcrete development and tufa growth. The presence of in situ rhizoconcretions and insect trace fossils (Celliforma sp. and Coprinisphaera sp.) and the distinctive carbonate microfabric confirm that the pink deposit is a pedogenic calcrete, not a calcified cave sediment. Paleomagnetic and stratigraphic evidence indicates that a second, reversed polarity, fossil-bearing deposit (YRSS) is a younger fissure-fill formed within a solutional cavity of the normal polarity tufa and pink calcrete (PCS). These observations have implications for the dating, environment, and taphonomy of the site, and increase the likelihood of future fossil discoveries within the Buxton-Norlim Limeworks.

An Exploratory Review on the Potential of Artificial Intelligence for Early Detection of Acute Kidney Injury in Preterm Neonates.

A preterm birth is a live birth that occurs before 37 completed weeks of pregnancy. Approximately 15 million babies are born preterm annually worldwide, indicating a global preterm birth rate of about 11%. Up to 50% of premature neonates in the gestational age (GA) group of <29 weeks' gestation will develop acute kidney injury (AKI) in the neonatal period; this is associated with high mortality and morbidity. There are currently no proven treatments for established AKI, and no effective predictive tool exists. We propose that the development of advanced artificial intelligence algorithms with neural networks can assist clinicians in accurately predicting AKI. Clinicians can use pathology investigations in combination with the non-invasive monitoring of renal tissue oxygenation (rSO2) and renal fractional tissue oxygenation extraction (rFTOE) using near-infrared spectroscopy (NIRS) and the renal resistive index (RRI) to develop an effective prediction algorithm. This algorithm would potentially create a therapeutic window during which the treating clinicians can identify modifiable risk factors and implement the necessary steps to prevent the onset and reduce the duration of AKI.

Towards Non-Invasive and Continuous Blood Pressure Monitoring in Neonatal Intensive Care Using Artificial Intelligence: A Narrative Review.

Preterm birth is a live birth that occurs before 37 completed weeks of pregnancy. Approximately 11% of babies are born preterm annually worldwide. Blood pressure (BP) monitoring is essential for managing the haemodynamic stability of preterm infants and impacts outcomes. However, current methods have many limitations associated, including invasive measurement, inaccuracies, and infection risk. In this narrative review, we find that artificial intelligence (AI) is a promising tool for the continuous measurement of BP in a neonatal cohort, based on data obtained from non-invasive sensors. Our findings highlight key sensing technologies, AI techniques, and model assessment metrics for BP sensing in the neonatal cohort. Moreover, our findings show that non-invasive BP monitoring leveraging AI has shown promise in adult cohorts but has not been broadly explored for neonatal cohorts. We conclude that there is a significant research opportunity in developing an innovative approach to provide a non-invasive alternative to existing continuous BP monitoring methods, which has the potential to improve outcomes for premature babies.

Training community-based psychotherapists to maintain a therapeutic alliance: A psychotherapy practice research network study.

The goal of this study was to test the efficacy of training community-based psychotherapists who were part of a practice research network to be more attuned to their patients' experiences of the therapeutic relationship. We were particularly interested in the effect of therapist training on the congruence of alliance ratings with their patients. Forty psychotherapists who treated 117 patients were randomly assigned to receive either no training or training, whose learning objectives were to help therapists to develop and maintain a therapeutic alliance. The training included workshops and ongoing consultations to help the clinician to strengthen the therapeutic relationship with the use of mentalizing, attachment theory, countertransference management, and metacommunication. Therapeutic alliance and well-being outcomes were measured at each of six consecutive early psychotherapy sessions. We used the truth and bias model and response surface analysis within a multilevel modeling context to test hypotheses. There was a significantly faster rate of alliance growth in the training versus the no training condition when the alliance was rated by therapists, but not when rated by patients. Trained therapists experienced greater temporal congruence in alliance ratings with their patients compared to untrained therapists. Patient well-being outcomes improved in a session when trained therapists and their patients agreed in their positive alliance ratings in a previous session. This association not significant among untrained therapists. Training therapists in key interpersonally focused skills may lead them to be better attuned to their patients' experiences of the therapeutic relationship.

Mechanisms to enhance racial equity in health care: Developing a model to facilitate translation of the ACCURE intervention.

Background: As medical and public health professional organizations call on researchers and policy makers to address structural racism in health care, guidance on evidence-based interventions to enhance health care equity is needed. The most promising organizational change interventions to reduce racial health disparities use multilevel approaches and are tailored to specific settings. This study examines the Accountability for Cancer Care through Undoing Racism and Equity (ACCURE) intervention, which changed systems of care at two U.S. cancer centers and eliminated the Black-White racial disparity in treatment completion among patients with early-stage breast and lung cancer. Purpose: We aimed to document key characteristics of ACCURE to facilitate translation of the intervention in other care settings. Methods: We conducted semi-structured interviews with participants who were involved in the design and implementation of ACCURE and analyzed their responses to identify the intervention's mechanisms of change and key components. Results: Study participants (n = 18) described transparency and accountability as mechanisms of change that were operationalized through ACCURE's key components. Intervention components were designed to enhance either institutional transparency (e.g., a data system that facilitated real-time reporting of quality metrics disaggregated by patient race) or accountability of the care system to community values and patient needs for minimally biased, tailored communication and support (e.g., nurse navigators with training in antiracism and proactive care protocols). Conclusions: The antiracism principles transparency and accountability may be effective change mechanisms in equity-focused health services interventions. The model presented in this study can guide future research aiming to adapt ACCURE and evaluate the intervention's implementation and effectiveness in new settings and patient populations.

The 2023 wearable photoplethysmography roadmap.

Photoplethysmography is a key sensing technology which is used in wearable devices such as smartwatches and fitness trackers. Currently, photoplethysmography sensors are used to monitor physiological parameters including heart rate and heart rhythm, and to track activities like sleep and exercise. Yet, wearable photoplethysmography has potential to provide much more information on health and wellbeing, which could inform clinical decision making. This Roadmap outlines directions for research and development to realise the full potential of wearable photoplethysmography. Experts discuss key topics within the areas of sensor design, signal processing, clinical applications, and research directions. Their perspectives provide valuable guidance to researchers developing wearable photoplethysmography technology.

A prospective, multicenter study of pharmacist activities resulting in medication error interception in the emergency department.

STUDY OBJECTIVE: The primary objective of this study is to determine the activities of pharmacists that lead to medication error interception in the emergency department (ED). METHODS: This was a prospective, multicenter cohort study conducted in 4 geographically diverse academic and community EDs in the United States. Each site had clinical pharmacy services. Pharmacists at each site recorded their medication error interceptions for 250 hours of cumulative time when present in the ED (1,000 hours total for all 4 sites). Items recorded included the activities of the pharmacist that led to medication error interception, type of orders, phase of medication use process, and type of error. Independent evaluators reviewed all medication errors. Descriptive analyses were performed for all variables. RESULTS: A total of 16,446 patients presented to the EDs during the study, resulting in 364 confirmed medication error interceptions by pharmacists. The pharmacists' activities that led to medication error interception were as follows: involvement in consultative activities (n=187; 51.4%), review of medication orders (n=127; 34.9%), and other (n=50; 13.7%). The types of orders resulting in medication error interceptions were written or computerized orders (n=198; 54.4%), verbal orders (n=119; 32.7%), and other (n=47; 12.9%). Most medication error interceptions occurred during the prescribing phase of the medication use process (n=300; 82.4%) and the most common type of error was wrong dose (n=161; 44.2%). CONCLUSION: Pharmacists' review of written or computerized medication orders accounts for only a third of medication error interceptions. Most medication error interceptions occur during consultative activities.

Racism Runs Through It: Examining The Sexual And Reproductive Health Experience Of Black Women In The South.

Few studies have illustrated how racism influences Black women's use of reproductive health care services. This article presents findings of a collaborative study conducted by a research team and a reproductive justice organization to understand Black women's concerns with sexual and reproductive health services. The qualitative research was conducted with Black women living in Georgia and North Carolina, using a community-based participatory research approach. Themes were developed from participant accounts that highlight how racism, both structural and individual, influenced their reproductive health care access, utilization, and experience. Structural racism affected participants' finances and led some to forgo care or face barriers to obtaining care. Individual racism resulted in some women electing to receive care only from same-race medical providers. These findings suggest a need for policies and practices that address structural barriers to reproductive health care access and improve the reproductive health experience of Black women.

Effect of an Antiracism Intervention on Racial Disparities in Time to Lung Cancer Surgery.

PURPOSE: Timely lung cancer surgery is a metric of high-quality cancer care and improves survival for early-stage non-small-cell lung cancer. Historically, Black patients experience longer delays to surgery than White patients and have lower survival rates. Antiracism interventions have shown benefits in reducing racial disparities in lung cancer treatment. METHODS: We conducted a secondary analysis of Accountability for Cancer Care through Undoing Racism and Equity, an antiracism prospective pragmatic trial, at five cancer centers to assess the impact on overall timeliness of lung cancer surgery and racial disparities in timely surgery. The intervention consisted of (1) a real-time warning system to identify unmet care milestones, (2) race-specific feedback on lung cancer treatment rates, and (3) patient navigation. The primary outcome was surgery within 8 weeks of diagnosis. Risk ratios (RRs) and 95% CIs were estimated using log-binomial regression and adjusted for clinical and demographic factors. RESULTS: A total of 2,363 patients with stage I and II non-small-cell lung cancer were included in the analyses: intervention (n = 263), retrospective control (n = 1,798), and concurrent control (n = 302). 87.1% of Black patients and 85.4% of White patients in the intervention group (P = .13) received surgery within 8 weeks of diagnosis compared with 58.7% of Black patients and 75.0% of White patients in the retrospective group (P < .01) and 64.9% of Black patients and 73.2% of White patients (P = .29) in the concurrent group. Black patients in the intervention group were more likely to receive timely surgery than Black patients in the retrospective group (RR 1.43; 95% CI, 1.26 to 1.64). White patients in the intervention group also had timelier surgery than White patients in the retrospective group (RR 1.10; 95% CI, 1.02 to 1.18). CONCLUSION: Accountability for Cancer Care through Undoing Racism and Equity is associated with timelier lung cancer surgery and reduction of the racial gap in timely surgery.
