Characteristics of Lung Cancer Patients With Asymptomatic or Undiagnosed SARS-CoV-2 Infections.

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be spread by individuals unaware they are infected. Such dissemination has heightened ramifications in cancer patients, who may need to visit healthcare facilities frequently, be exposed to immune-compromising therapies, and face greater morbidity from coronavirus disease 2019 (COVID-19). We determined characteristics of (1) asymptomatic, clinically diagnosed, and (2) serologically documented but clinically undiagnosed SARS-CoV-2 infection among individuals with lung cancer. PATIENTS AND METHODS: In a multicenter registry, individuals with lung cancer (regardless of prior SARS-CoV-2 vaccination or documented infection) underwent collection of clinical data and serial blood samples, which were tested for antinucleocapsid protein antibody (anti-N Ab) or IgG (N) levels. We used multivariable logistic regression models to investigate clinical characteristics associated with the presence or absence of symptoms and the presence or absence of a clinical diagnosis among patients with their first SARS-CoV-2 infection. RESULTS: Among patients with serologic evidence or clinically documented SARS-CoV-2 infection, 80/142 (56%) had no reported symptoms at their first infection, and 61/149 (40%) were never diagnosed. Asymptomatic infection was more common among older individuals and earlier-stage lung cancer. In multivariable analysis, non-white individuals with SARS-CoV-2 serologic positivity were 70% less likely ever to be clinically diagnosed (P = .002). CONCLUSIONS: In a multicenter lung cancer population, a substantial proportion of SARS-CoV-2 infections had no associated symptoms or were never clinically diagnosed. Because such cases appear to occur more frequently in populations that may face greater COVID-19-associated morbidity, measures to limit disease spread and severity remain critical.

"A whole ball of all-togetherness": The interwoven experiences of intimate partner violence, brain injury, and mental health.

BACKGROUND: Intimate partner violence (IPV) is a global public health crisis, with physical violence leaving IPV survivors at high risk of brain injury (BI). Both BI and IPV have significant physical, psychological, cognitive, and social impacts, including a high risk of mental health concerns, yet there is limited exploration of IPV survivors' experiences with BI and mental health. This study aimed to explore the BI- and mental health-related needs and experiences of IPV survivors from the perspectives of survivors and service providers with the objective of developing knowledge translation materials to raise awareness and support survivors and service providers in addressing these concerns. METHODS: This qualitative interpretive description study involved 19 semi-structured interviews and two focus group discussions (2-3 participants each) with 24 participants including IPV survivors experiencing BI and mental health concerns as well as IPV, mental health, and BI service providers between October 2020 and February 2021. Three screening questions were used to identify probable BI among survivors. Participants across groups were an average of 48.5±12.7 years old and were predominantly cisgender women (96%), of European origin (75%), with a university degree (71%). Interviews were recorded, transcribed, and thematically analyzed. FINDINGS: Across interviews, participants spoke about IPV, BI, and mental health as being complex and interrelated experiences that have impacts across the survivor's life and extend well beyond the abusive relationship. Because of the underrecognized nature of BI in IPV, finding and accessing care requires persistence that survivors spoke of as being like "a full-time job." The benefit of making meaningful connections, particularly with other survivors, was highlighted. CONCLUSIONS: Recognition of BI as a contributing factor shaping the lived experience of IPV survivors; acknowledgement that the impacts of IPV, BI, and mental health are far reaching and long lasting; and reducing barriers to finding and accessing appropriate care are critical to better supporting IPV survivors with BI and mental health concerns. Clinicians should consider BI and its lingering impacts among the IPV survivors with whom they work. Health and social policy that supports integration of care and the reduction of unnecessary barriers should be a priority.

ABSTRACT: This article reviews inflammatory versus anti-inflammatory foods, autoimmune and inflammatory disorders, the benefits of specific anti-inflammatory diets, and strategies for nurses to partner with individuals, while considering culture and food preferences, to promote healthy eating habits and prevent diseases.

Linking Inter-professional Newborn and Contraception Care (LINCC) trial: Protocol for a stepped wedge cluster randomized trial to link postpartum contraception care with routine Well-Baby Visits.

BACKGROUND: Pregnancies conceived within 18 months of a prior delivery (termed short inter-pregnancy interval [IPI]) place mothers and infants at high risk for poor health outcomes. Despite this, nearly one third of U.S. women experience a short IPI. OBJECTIVE: To address the gap in the current model of postpartum (PP) contraception care by developing and implementing a novel approach to link (co-schedule) PP contraception care with newborn well-baby care to improve access to timely PP contraception. METHODS: The LINCC Trial will take place in seven clinical locations across five community health centers within the U.S. PP patients (planned n = 3150) who are attending a Well-Baby Visit between 0 and 6 months will be enrolled. The LINCC Trial aims to leverage the Electronic Health Record to prompt providers to ask PP patients attending a Well-Baby Visit about their PP contraception needs and facilitate co-scheduling of PP contraception care with routine newborn care visits. The study includes a cluster randomized, cross-sectional stepped wedge design to roll out the intervention across the seven sites. The outcomes of the study include receipt of most or moderately effective methods of contraception by two and six months PP; and rate of short IPI pregnancies. Implementation outcomes will be assessed at baseline and 6 months after site enters intervention period. CONCLUSIONS: The LINCC Trial seeks to evaluate the effectiveness and feasibility of a linked care model in comparison to usual care.

Electrical Stimulation: How It Works and How to Apply It.

Electrical stimulation is emerging as a perioperative strategy to improve peripheral nerve regeneration and enhance functional recovery. Despite decades of research, new insights into the complex multifaceted mechanisms of electrical stimulation continue to emerge, providing greater understanding of the neurophysiology of nerve regeneration. In this study, we summarize what is known about how electrical stimulation modulates the molecular cascades and cellular responses innate to nerve injury and repair, and the consequential effects on axonal growth and plasticity. Further, we discuss how electrical stimulation is delivered in preclinical and clinical studies and identify knowledge gaps that may provide opportunities for optimization.

Biological and genetic determinants of glycolysis: Phosphofructokinase isoforms boost energy status of stored red blood cells and transfusion outcomes.

Mature red blood cells (RBCs) lack mitochondria and thus exclusively rely on glycolysis to generate adenosine triphosphate (ATP) during aging in vivo or storage in blood banks. Here, we leveraged 13,029 volunteers from the Recipient Epidemiology and Donor Evaluation Study to identify associations between end-of-storage levels of glycolytic metabolites and donor age, sex, and ancestry-specific genetic polymorphisms in regions encoding phosphofructokinase 1, platelet (detected in mature RBCs); hexokinase 1 (HK1); and ADP-ribosyl cyclase 1 and 2 (CD38/BST1). Gene-metabolite associations were validated in fresh and stored RBCs from 525 Diversity Outbred mice and via multi-omics characterization of 1,929 samples from 643 human RBC units during storage. ATP and hypoxanthine (HYPX) levels-and the genetic traits linked to them-were associated with hemolysis in vitro and in vivo, both in healthy autologous transfusion recipients and in 5,816 critically ill patients receiving heterologous transfusions, suggesting their potential as markers to improve transfusion outcomes.

Time-Dependent Effects of Clinical Interventions on SARS-CoV-2 Immunity in Patients with Lung Cancer.

In patients with lung cancer (LC), understanding factors that impact the dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) anti-spike antibody (SAb) titers over time is critical, but challenging, due to evolving treatments, infections, vaccinations, and health status. The objective was to develop a time-dependent regression model elucidating individual contributions of factors influencing SAb levels in LC patients using a prospective, longitudinal, multi-institutional cohort study initiated in January 2021. The study evaluated 296 LC patients-median age 69; 55% female; 50% stage IV. Blood samples were collected every three months to measure SAb levels using FDA-approved ELISA. Asymptomatic and unreported infections were documented through measurement of anti-nucleocapsid Ab levels (Meso Scale Discovery). Associations between clinical characteristics and titers were evaluated using a time-dependent linear regression model with a generalized estimating equation (GEE), considering time-independent variables (age, sex, ethnicity, smoking history, histology, and stage) and time-dependent variables (booster vaccinations, SARS-CoV-2 infections, cancer treatment, steroid use, and influenza vaccination). Significant time-dependent effects increasing titer levels were observed for prior SARS-CoV-2 infection (p < 0.001) and vaccination/boosters (p < 0.001). Steroid use (p = 0.043) and chemotherapy (p = 0.033) reduced titer levels. Influenza vaccination was associated with increased SAb levels (p < 0.001), independent of SARS-CoV-2 vaccine boosters. Prior smoking significantly decreased titers in females (p = 0.001). Age showed no association with titers. This GEE-based linear regression model unveiled the nuanced impact of multiple variables on patient anti-spike Ab levels over time. After controlling for the major influences of vaccine and SARS-CoV-2 infections, chemotherapy and steroid use were found to have negatively affected titers. Smoking in females significantly decreased titers. Surprisingly, influenza vaccinations were also significantly associated, likely indirectly, with improved SARS-CoV-2 titers.

A Modification to the Brand Transfer for Claw Hand: The Four-Tailed Extensor Carpi Radialis Brevis to Lateral Band Transfer.

BACKGROUND: Claw deformity is a devastating consequence of low ulnar nerve palsy, resulting in loss of finger function. Traditionally, the Brand transfer is a favored intervention but requires lengthy grafts and bulky tenorrhaphies, risking adhesions in the lumbrical canal. We present a modified Brand tendon transfer, which extends the extensor carpi radialis brevis (ECRB) into 4 tails for individual grafting into the lateral band, decreasing adhesion risk and graft length need. METHODS: Nine consecutive patients with claw hand were examined in detail to confirm the diagnosis and appropriateness for claw-correction surgery by the senior author. All patients underwent our modified Brand transfer. Follow-up for a minimum of 6 months was pursued for each patient, with range of motion, grip strength, and pinch strength recorded at that time. RESULTS: Treated patients demonstrate maintained grip and pinch strength, coordinated grasp, and improvement in metacarpophalangeal posture. One patient required reoperation for extensive scarring and underwent tenolysis of the tendon grafts and revision grafting for the small finger. CONCLUSION: We concluded that our modified weave of a 4-tailed tendon graft through the ECRB is a synergistic transfer that maintains acceptable hand strength in the setting of a chronic low ulnar nerve palsy with a lower risk of tendon adhesion and length of grafting, offering an additional tool in the armamentarium of the hand surgeon approaching the ulnar nerve-injured hand.

Applying the Family Stress Model to responsive feeding and early obesity prevention.

Rapid weight gain during infancy and obesity during early childhood may lead to adverse health outcomes during later childhood and into adulthood, especially in families experiencing economic hardship. Families experiencing economic hardship may also experience food insecurity, which can impact child development and responsive feeding, an important target for obesity prevention in early life. The Family Stress Model suggests that stress, particularly economic hardship, can negatively impact parents' mental health, parenting, and quality of family relationships. This review proposes a conceptual model that expands upon the original Family Stress Model by including parent-child dyadic interactions during feeding (i.e., responsive feeding) as well as the coparenting relationship around feeding. Our conceptual model integrates responsive feeding into the Family Stress Model and includes the impact of food insecurity on feeding and child health outcomes. Such models that consider multiple influences on child development have implications for the design of effective interventions to promote healthy growth for entire families. Future directions in this research will empirically test the model and explore early intervention strategies that aim to promote responsive feeding, nutrition security, and health within families. Continuing interdisciplinary research between the fields of nutrition and family development will be key to addressing the complex interplay of family stressors, parent responsiveness, and childhood obesity.

Backgrounds and perspectives of San Antonio street sleepers.

Background: The question of what brings someone to homelessness and keeps them there has many varied and complex answers. The authors believe the answers lie within the persons experiencing homelessness (PEH). Methods: This is an interpretive approach study based on convenience sampling of the San Antonio, TX, unsheltered population, utilizing semi-structured interviews from January 2022 through November 2022. Results: The six most common themes that emerged from the subjects' backgrounds were 1) jail or prison time or other personally significant legal issues; 2) personal substance abuse or addiction struggles; 3) physical and mental health challenges as an adult; 4) disdain of shelters and preference for rough sleeping; 5) a problematic childhood; 6) did not enjoy school as a child or young adult. Conclusion: To gain more insight into a situation as complex as the state of homelessness, researchers should meet with those on the frontline of this epidemic and hear first-hand their personal histories, challenges, successes, and suggestions. Though not a novel approach, the researchers found limited previous literature in regard to approach, scope and in relation of causation related to homelessness, especially about the U.S. unsheltered population. The ultimate goal is for such research to help guide outreach services and legislation related to PEH.

Patient experiences using public and private insurance coverage for abortion in Illinois: Implementation successes and remaining gaps.

CONTEXT: Insurance coverage for abortion in states where care remains legal can alleviate financial burdens for patients and increase access. Recent policy changes in Illinois required Medicaid and some private insurance plans to cover abortion care. This study explores policy implementation from the perspectives of patients using their insurance to obtain early abortion care. METHODOLOGY: Between July 2021 and February 2022, we interviewed Illinois residents who recently sought abortion care at ≤11 weeks of pregnancy. We also interviewed nine key informants with experience providing or billing for abortion or supporting insurance policy implementation in Illinois. We coded interview transcripts in Dedoose and developed code summaries to identify salient themes across interviews. RESULTS: Most participants insured by Illinois Medicaid or eligible for enrollment received full coverage for their abortions; most with private insurance did not and faced challenges learning about coverage status. Some opted not to use insurance, often citing privacy concerns. Participants who benefited from abortion coverage expressed relief, gave examples of other financial challenges they could prioritize, and described feeling in control of their abortion experience. Those without coverage described feeling stressed, uncertain, and constrained in their decision-making. CONCLUSION: When abortion was fully covered by insurance, it reduced financial burdens and enhanced reproductive autonomy. Illinois Medicaid policy-with seamless enrollment options and appropriate reimbursement rates-offers a model for improving abortion access in other states. Further investigation is needed to determine compliance among private insurance companies and increase transparency.

A Perspective on Electrical Stimulation and Sympathetic Regeneration in Peripheral Nerve Injuries.

Peripheral nerve injuries (PNIs) are common and devastating. The current standard of care relies on the slow and inefficient process of nerve regeneration after surgical intervention. Electrical stimulation (ES) has been shown to both experimentally and clinically result in improved regeneration and functional recovery after PNI for motor and sensory neurons; however, its effects on sympathetic regeneration have never been studied. Sympathetic neurons are responsible for a myriad of homeostatic processes that include, but are not limited to, blood pressure, immune response, sweating, and the structural integrity of the neuromuscular junction. Almost one quarter of the axons in the sciatic nerve are from sympathetic neurons, and their importance in bodily homeostasis and the pathogenesis of neuropathic pain should not be underestimated. Therefore, as ES continues to make its way into patient care, it is not only important to understand its impact on all neuron subtypes, but also to ensure that potential adverse effects are minimized. This piece gives an overview of the effects of ES in animals models and in humans while offering a perspective on the potential effects of ES on sympathetic axon regeneration.

Understanding communication between patients and healthcare professionals regarding comprehensive biomarker testing in precision oncology: A scoping review.

BACKGROUND: Precision oncology, using comprehensive biomarker testing (cBT) to inform individual cancer diagnosis, prognosis and treatment, includes increasingly complex technology and clinical data sets. People impacted by cancer (patients and caregivers) and healthcare professionals (HCPs) face distinct challenges in navigating the cBT and personalized treatment landscape. This review summarizes evidence regarding cBT-related communication between people impacted by cancer and HCPs and identifies important avenues for future research in precision oncology. METHODS: A scoping review was conducted using records published in PubMed during January 2017-August 2022, focusing on the breadth of topics on patient-HCP communication and knowledge resources used by HCPs as guidance in cBT-related communication. Data were extracted from records meeting inclusion criteria, and findings were summarized according to main topics. RESULTS: The search identified 287 unique records and data were extracted from 42 records, including nine from expert input. Most records originated from the United States included patients with different types of cancer, and oncologists were the main HCPs. Patients' motivation for undergoing cBT and receiving results was generally high in different settings. However, patients' understanding of cBT-related concepts was limited, and their knowledge and information preferences changed based on cBT implications and significance to family members. HCPs were valued by patients as a trusted source of information. Limited evidence was available on HCPs' information-seeking behavior and factors influencing cBT-related knowledge and confidence, often self-reported as insufficient. CONCLUSIONS: Patient education by knowledgeable and confident HCPs, information management and a caring patient-HCP relationship communicating continuity of care regardless of cBT results are crucial to empower patients and shared decision-making in precision oncology. More data on the process and structure of cBT-related communication, distinction between and characterization of different timepoints of patient-HCP interactions are needed.

Educating Future Generations of Surgeons across Borders: Novel Global Linked Hybrid Live Cadaveric Peripheral Nerve Surgical Training Course.

Background: This study aimed to evaluate a novel, multi-site, technology-facilitated education and training course in peripheral nerve surgery. The program was developed to address the training gaps in this specialized field by integrating a structured curriculum, high-fidelity cadaveric dissection, and surgical simulation with real-time expert guidance. Methods: A collaboration between the Global Nerve Foundation and Esser Masterclass facilitated the program, which was conducted across three international sites. The curriculum was developed by a panel of experienced peripheral nerve surgeons and included both text-based and multimedia resources. Participants' knowledge and skills were assessed using pre- and postcourse questionnaires. Results: A total of 73 participants from 26 countries enrolled and consented for data usage for research purposes. The professional background was diverse, including hand surgeons, plastic surgeons, orthopedic surgeons, and neurosurgeons. Participants reported significant improvements in knowledge and skills across all covered topics (p < 0.001). The course received a 100% recommendation rate, and 88% confirmed that it met their educational objectives. Conclusions: This study underscores the potential of technology-enabled, collaborative expert-led training programs in overcoming geographical and logistical barriers, setting a new standard for globally accessible, high-quality surgical training. It highlights the practical and logistical challenges of multi-site training, such as time zone differences and participant fatigue. It also provides practical insights for future medical educational endeavors, particularly those that aim to be comprehensive, international, and technologically facilitated.

It also explores specific food intolerances such as lactose intolerance, nonceliac gluten sensitivity, fructose intolerance, and salicylate sensitivity.

Biological and Genetic Determinants of Glycolysis: Phosphofructokinase Isoforms Boost Energy Status of Stored Red Blood Cells and Transfusion Outcomes.

Mature red blood cells (RBCs) lack mitochondria, and thus exclusively rely on glycolysis to generate adenosine triphosphate (ATP) during aging in vivo or storage in the blood bank. Here we leveraged 13,029 volunteers from the Recipient Epidemiology and Donor Evaluation Study to identify an association between end-of-storage levels of glycolytic metabolites and donor age, sex, and ancestry-specific genetic polymorphisms in regions encoding phosphofructokinase 1, platelet (detected in mature RBCs), hexokinase 1, ADP-ribosyl cyclase 1 and 2 (CD38/BST1). Gene-metabolite associations were validated in fresh and stored RBCs from 525 Diversity Outbred mice, and via multi-omics characterization of 1,929 samples from 643 human RBC units during storage. ATP and hypoxanthine levels - and the genetic traits linked to them - were associated with hemolysis in vitro and in vivo, both in healthy autologous transfusion recipients and in 5,816 critically ill patients receiving heterologous transfusions, suggesting their potential as markers to improve transfusion outcomes. Highlights: Blood donor age and sex affect glycolysis in stored RBCs from 13,029 volunteers;Ancestry, genetic polymorphisms in PFKP, HK1, CD38/BST1 influence RBC glycolysis;Modeled PFKP effects relate to preventing loss of the total AXP pool in stored RBCs;ATP and hypoxanthine are biomarkers of hemolysis in vitro and in vivo.

Exploring the Relationships Between Rehabilitation and Survivors of Intimate Partner Violence: A Scoping Review.

Intimate partner violence (IPV) is a public health crisis affecting one in three women and one in ten men in their lifetimes. Rehabilitation professionals are highly likely to encounter survivors of IPV in their practice; yet, there exists no formal review assessing the relationship between IPV and rehabilitation. Our objective was to understand the types and contexts of rehabilitation care currently available for survivors of IPV, opportunities identified in the literature for rehabilitation care, and IPV awareness and education among rehabilitation providers. A search strategy related to IPV and four rehabilitation professionals of interest (occupational therapy, physiotherapy, speech-language pathology/therapy, and physiatry) was developed across 10 databases and complemented by a gray literature search. Two reviewers independently assessed articles for inclusion. In all, 44 articles met inclusion criteria, ranging from primary research articles (48%) to clinical newsletters. Included articles predominantly focused on opportunities for rehabilitation care (68%) and occupational therapists as a profession (68%). A minority of studies examined specific interventions for IPV survivors (18%) or assessed for knowledge and attitudes about IPV (16%) among rehabilitation professionals. To our knowledge, this is the first scoping review exploring the rehabilitation literature for IPV survivors. These findings show an awareness of IPV among rehabilitation professionals, the importance of identifying IPV in clients, and the ways in which rehabilitation professionals are uniquely situated to support survivors of IPV. There remains an opportunity to explore interventions designed specifically for IPV survivors.

Pharmacists' experiences dispensing misoprostol and readiness to dispense mifepristone.

BACKGROUND: Mifepristone, followed by misoprostol, is commonly used for medication abortion and early miscarriage care. Since mifepristone's approval in 2000, the Food and Drug Administration (FDA) has placed restrictions on where and how it could be dispensed, including applying a Risk Evaluation and Mitigation Strategy in 2011. In December 2021, the FDA removed the in-person dispensing requirement and, in January 2023, began allowing certified pharmacies to dispense the drug directly to patients. OBJECTIVES: To explore pharmacist knowledge about misoprostol and mifepristone, experience dispensing misoprostol, as well as comfort and readiness to dispense mifepristone should federal regulations allow. METHODS: We conducted in-depth interviews with 21 U.S.-based pharmacists and pharmacy trainees between June and December of 2021, a time when few pharmacists were allowed to dispense mifepristone. RESULTS: Participants reported varied knowledge about medications for miscarriage and abortion but described themselves as generally knowledgeable about medications and reported strategies for learning about new medications. Most said they would feel ready to dispense mifepristone, and many described dispensing misoprostol without difficulty. Potential challenges specific to mifepristone dispensing included employer hesitation and colleague refusals. To assure successful dispensing, participants recommended basic training and fact sheets; relationships with prescribers for follow-up; and policies for prescription transfers in the event of refusal. CONCLUSIONS: We found that nearly all participants would feel ready to dispense mifepristone with some basic training. Pharmacists self-report having the skills and resources to learn about new medications quickly. Our findings support the FDA's rule change allowing pharmacist dispensing of mifepristone and suggest that most challenges would stem from individual or institutional refusals.

Regulation of kynurenine metabolism by blood donor genetics and biology impacts red cell hemolysis in vitro and in vivo.

ABSTRACT: In the field of transfusion medicine, the clinical relevance of the metabolic markers of the red blood cell (RBC) storage lesion is incompletely understood. Here, we performed metabolomics of RBC units from 643 donors enrolled in the Recipient Epidemiology and Donor Evaluation Study, REDS RBC Omics. These units were tested on storage days 10, 23, and 42 for a total of 1929 samples and also characterized for end-of-storage hemolytic propensity after oxidative and osmotic insults. Our results indicate that the metabolic markers of the storage lesion poorly correlated with hemolytic propensity. In contrast, kynurenine was not affected by storage duration and was identified as the top predictor of osmotic fragility. RBC kynurenine levels were affected by donor age and body mass index and were reproducible within the same donor across multiple donations from 2 to 12 months apart. To delve into the genetic underpinnings of kynurenine levels in stored RBCs, we thus tested kynurenine levels in stored RBCs on day 42 from 13 091 donors from the REDS RBC Omics study, a population that was also genotyped for 879 000 single nucleotide polymorphisms. Through a metabolite quantitative trait loci analysis, we identified polymorphisms in SLC7A5, ATXN2, and a series of rate-limiting enzymes (eg, kynurenine monooxygenase, indoleamine 2,3-dioxygenase, and tryptophan dioxygenase) in the kynurenine pathway as critical factors affecting RBC kynurenine levels. By interrogating a donor-recipient linkage vein-to-vein database, we then report that SLC7A5 polymorphisms are also associated with changes in hemoglobin and bilirubin levels, suggestive of in vivo hemolysis in 4470 individuals who were critically ill and receiving single-unit transfusions.
