RESUMEN
Atrial fibrillation (AF) is strongly associated with risk of stroke and heart failure. AF promotes atrial remodeling that increases risk of stroke due to left atrial thrombogenesis, and increases energy demand to support high rate electrical activity and muscle contraction. While many transcriptomic studies have assessed AF-related changes in mRNA abundance, fewer studies have assessed proteomic changes. We performed a proteomic analysis on left atrial appendage (LAA) tissues from 12 patients with a history of AF undergoing elective surgery; atrial rhythm was documented at time of surgery. Proteomic analysis was performed using liquid chromatography with mass spectrometry (LC/MS-MS). Data-dependent analysis identified 3090 unique proteins, with 408 differentially expressed between sinus rhythm and AF. Ingenuity Pathway Analysis of differentially expressed proteins identified mitochondrial dysfunction, oxidative phosphorylation, and sirtuin signaling among the most affected pathways. Increased abundance of electron transport chain (ETC) proteins in AF was accompanied by decreased expression of ETC complex assembly factors, tricarboxylic acid cycle proteins, and other key metabolic modulators. Discordant changes were also evident in the contractile unit with both up and downregulation of key components. Similar pathways were affected in a comparison of patients with a history of persistent vs. paroxysmal AF, presenting for surgery in sinus rhythm. Together, these data suggest that while the LAA attempts to meet the energetic demands of AF, an uncoordinated response may reduce ATP availability, contribute to tissue contractile and electrophysiologic heterogeneity, and promote a progression of AF from paroxysmal episodes to development of a substrate amenable to persistent arrhythmia.

Because of its proximity to and frequent travelers to and from China, Taiwan faces complex challenges in preventing coronavirus disease (COVID-19). As soon as China reported the unidentified outbreak to the World Health Organization on December 31, 2019, Taiwan assembled a taskforce and began health checks onboard flights from Wuhan. Taiwan's rapid implementation of disease prevention measures helped detect and isolate the country's first COVID-19 case on January 20, 2020. Laboratories in Taiwan developed 4-hour test kits and isolated 2 strains of the coronavirus before February. Taiwan effectively delayed and contained community transmission by leveraging experience from the 2003 severe acute respiratory syndrome outbreak, prevalent public awareness, a robust public health network, support from healthcare industries, cross-departmental collaborations, and advanced information technology capacity. We analyze use of the National Health Insurance database and critical policy decisions made by Taiwan's government during the first 50 days of the COVID-19 outbreak.

BACKGROUND: In the United States, post-cardiac arrest debriefing has increased, but historically it has occurred rarely in our pediatric intensive care unit (PICU). A fellow-led debriefing tool was developed as a tool for fellow development, as well as to enhance communication amongst a multidisciplinary team. METHODS: A curriculum and debriefing tool for fellow facilitators was developed and introduced in a 41-bed cardiac and medical PICU. Pre- and post-intervention surveys were sent to multidisciplinary PICU providers to assess effectiveness of debriefings using newly-trained leaders, as well as changes in team communication. RESULTS: Debriefing occurred after 84% (63/75) of cardiac arrests post-intervention. Providers in various team roles participated in pre-intervention (129 respondents/236 invitations) and post-intervention (96 respondents /232 invitations) surveys. Providers reported that frequently occurring debriefings increased from 9 to 58%, pre- and post-intervention respectively (p < .0001). Providers reported frequent identification and discussion of learning points increased from 32% pre- to 63% post-intervention. In the 12 months post-intervention, 62% of providers agreed that the overall quality of communication during arrests had improved, and 61% would be more likely to request a debriefing after cardiac arrest. CONCLUSION: The introduction of a fellow-led debriefing tool resulted in regularly performed debriefings after arrests. Despite post-intervention debriefings being led by newly-trained facilitators, the majority of PICU staff expressed satisfaction with the quality of debriefing and improvement in communication during arrests, suggesting that fellow facilitators can be effective debrief leaders.

INTRODUCTION: Rheumatoid arthritis (RA) is a common disease that requires patient self-management with chronic medications. Adherence rates for RA medications are suboptimal. This study explores medication adherence and self-efficacy behaviors among RA patients. METHODS: We conducted a qualitative study comprising focus groups and individual interviews. Nineteen participants were recruited and screened to participate in three 90-minute focus groups (n = 13) and six 60-minute individual interviews. We created and maintained a codebook to analyze data. Interviews were analyzed by using NViVo qualitative analysis software. RESULTS: Key points in participant interviews were 1) self-efficacy as influenced by the ability to establish routines, and having an understanding relationship with their healthcare provider; 2) self-efficacy to adjust medications depended on having permission from providers to adjust medications, perceptions of the effectiveness of medications, and confidence in self-knowledge to make appropriate adjustments; and 3) changes in self-efficacy over time were influenced by initial denial and later acceptance of the diagnosis. Participant interviews revealed that medication adherence is a spectrum that ranges from adherent to nonadherent. CONCLUSION: Participants' experience with RA medications revealed varied underlying reasons for adherence behaviors. Recognizing adherence as a dynamic behavior has important implications for how adherence interventions are designed. For example, participants reported adjusting medications in response to the unpredictable nature of RA. Interventions could collect information about RA symptoms and be tailored to provide adherence support at times when patients need it most. The importance of self-efficacy in influencing participants' adherence behaviors is an area for continuing research among patients and providers.

PURPOSE: The main objective was to compare post-operative outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction both with and without concomitant meniscus injury at a mean follow-up of 3.5 years. The secondary objective was to study the effect of different meniscal injury sites and treatment modalities on post-operative outcomes (PROS). METHODS: This is a retrospective analysis of a prospectively maintained database of patients undergoing ACL reconstruction at our tertiary institution between 2009 and 2012. Age, sex, graft type, graft fixation modality, location of meniscal tear and treatment (meniscal repair or meniscectomy) were recorded in the database. PROS used included the Tegner activity scale and the Lysholm score. RESULTS: There were no significant differences between patients with or without meniscal injury in terms of age, BMI or preoperative PROS. There was no significant difference in the post-operative outcome scores between patients with or without meniscal injury at a mean follow-up of 3.5 years. Regardless of the location of meniscal injury, the post-operative scores improved as compared to preoperative scores. CONCLUSION: Concomitant meniscal injury in cases of ACL reconstruction is not associated with poorer short-term post-operative PROS (mean follow-up time: 3.5 years). These findings may influence management decisions and help in preoperative counselling. LEVEL OF EVIDENCE: IV.

PURPOSE: In the past decade, there has been an increase in the development and use of oral anti-cancer medications (OAMs), especially for breast cancer-the most prevalent cancer in women. However, adherence rates for OAMs are often suboptimal, leading to lower survival rate, increased risk of recurrence, and higher healthcare costs. Our goal was to identify potentially modifiable psychosocial facilitators and barriers that may be targeted to increase OAM adherence for breast cancer patients. METHODS: We systematically searched PubMed for studies published in the U.S. by June 15, 2016 that addressed the following: (1) OAMs for breast cancer; (2) medication adherence; and (3) at least one psychosocial aspect of adherence. RESULTS: Of the 1752 papers screened, 21 articles were included and analyzed. The most commonly reported motivators for adherence are patient-provider relationships (n = 11 studied, 82% reported significant association) and positive views and beliefs of medication (n = 9 studied, 89% reported significant association). We also identified consistent evidence of the impact of depression and emotions, perception of illness, concern of side effects, self-efficacy in medication management and decision making, knowledge of medication, and social support on OAM adherence. CONCLUSIONS: Compared to traditional demographic, system, and clinical-related factors that have been well documented in the literature but are not easily changed, these cognitive, psychological, and interpersonal factors are more amendable via intervention and therefore could generate greater benefit in improving patient compliance and health outcomes. As OAMs shift treatment administration responsibility onto patients, continuous provider communication and education on illness and regimen are the keys to supporting patients' medication behavior.

Purpose: Hispanics, the largest minority in America, have increased risk of several medical issues and face noteworthy health disparities. This study compares care-seeking behaviors and choice experience among Hispanics, Asians, Blacks, and Whites, considering SES (income, education, and insurance status) and across five healthcare provider (HCP) types. Concurrent analysis provides a comprehensive view of how and where inequity manifests in healthcare. Methods: A cross-sectional online survey assessed 1485 adults (Hispanic=314, Asian=313, Black=316, White=542, recruited through a panel agency) of the frequency of visiting primary care providers, dentists, optometrists, gynecologists, and specialists for chronic conditions. Participants also rated the importance of self-selecting a HCP and difficulty in finding one. Results: Whites visited each HCP most regularly. Compared to Asians, more Hispanics saw specialists regularly (45.1% vs 56.5%, p=0.042), and Blacks saw dentists less (47.0% vs 38.3%, p=0.028) and gynecologists more often (21.2% vs 33.1%, p=0.024). No other frequency differences were observed among minorities. Low-income participants across four races saw dentists and gynecologists with comparable infrequency. Hispanics and Asians assigned similarly significantly lower self-choice importance and experienced more difficulty relative to Whites or Blacks. Participants with lower income or education visited HCPs less regularly yet perceived the same choice importance as higher-SES peers (p>0.05). Notably, discrepancies in visit frequency between Whites and minorities were more pronounced in higher-SES than lower-SES group. Differences in experiencing care-seeking difficulty were associated with income (p=0.029) and insurance type (p=0.009) but not education (p>0.05). Conclusion: Higher income and education increase healthcare utilization; however, racial disparities persist, particularly among higher-SES groups. Despite similarities among minorities, the extent of disparities varied by SES and provider type. The findings help explain evident inequity in healthcare access and health outcomes. Tailored patient education, culturally-specific navigation support, and more inclusive services are needed to address barriers faced by minorities and disadvantaged populations.
RESUMEN
INTRODUCTION: As patients become increasingly involved in healthcare decision-making, it is important to examine the drivers behind patient choice of doctor (PCOD); the initial decision can have lasting impacts on patients' trust in providers and health outcomes. However, limited studies have explored PCOD relative to socioeconomic status (SES) or health disparity. This review identified similar preferences and varied decision criteria in PCOD across SES groups. METHODS: PubMed, PsycINFO, Web of Science, and relevant cross-references were searched for articles published between January 2007-September 2022. Papers were screened using Covidence. Included studies examined PCOD by income and/or educational levels. Analysis was performed in 2022-2023. RESULTS: From 4,449 search results, 29 articles were selected (16 countries, 14 medical specialties, total of 32,651 participants). Individuals of higher SES ranked physician characteristics (e.g., qualifications, empathy) or performance more important than cost or convenience. Individuals of lower SES often had to prioritize logistical factors (e.g., insurance coverage, distance) due to resource constraints and gaps in knowledge or awareness about options. Despite differing healthcare systems, such divergence in PCOD were relatively consistent across countries. Some patients, especially females and disadvantaged groups, favored gender-concordant physicians for intimate medical matters (e.g., gynecologist); this partiality was not limited to conservative cultures. Few researchers investigated the outcomes of PCOD and indicated that lower-SES populations inadvertently chose, experienced, or perceived lower quality of care. DISCUSSION: Patients' decision criteria varied by SES, even under national systems intended for universal access, indicating the impacts of social determinants and structural inequities. Health education supporting patient decision-making and research on how SES affects PCOD and outcomes could help reduce health disparity.
RESUMEN
The COVID-19 booster first became available to all adults in the U.S. in November 2021 and a bivalent version in September 2022, but a large population remains booster-hesitant; only 17% of Americans have obtained the updated vaccine as of June 2023. We conducted two cross-sectional surveys in 2021 and 2022 (n = 1889 and 1319) to determine whether changes in booster-related feelings or perceptions had occurred and whether they altered vaccination rates over time. We found that both positive and negative emotions had grown stronger between the two years, with the prevalence of annoyance increasing the most (21.5% to 39.7%). The impact of trust on booster intention more than doubled (OR = 7.46 to 16.04). Although perceived risk of infection decreased, more participants in 2022 indicated uncertainty or unwillingness to obtain a new booster than in 2021, while the proportion refusing a booster remained constant at 22.5%. Confidence in the COVID-19 vaccine and feelings of hope from the booster motivated acceptance; both were stronger predictors of booster receptivity than prior vaccination history. Our findings signal a need to rebuild trust by informing people of their continued risk and appealing to positive, especially optimistic emotions to encourage booster uptake. Future research should explore longitudinal trends in behavior and feelings toward new booster doses and the impact of prolonged vaccine hesitancy on infection rates.
RESUMEN
Though available for all age groups in the US, only about half of those vaccinated have obtained a COVID-19 booster. Similar to the unvaccinated, those vaccinated-but-not-boosted may reduce the effectiveness of widespread viral protection. Booster hesitancy differs from general vaccine hesitancy yet remains less researched. We examined booster perceptions across vaccination status using qualitative methodologies. Four focus groups and 11 individual interviews (total n = 32) revealed nuanced changes and differences compared to the first-dose decision. Booster hesitancy stemmed from questions and surprises. Most vaccinated participants accepted the booster, though to varying degrees: enthusiastically with feelings of appreciation and added confidence, passively as an intuitive next step, indifferently following recommendation-"primed" by the yearly flu shot, and reluctantly with worries. The vaccinated-but-not-boosted group expressed confusion about the need for a new shot and discontentment as to why it was not communicated from the start, which coincided with their uncertainty about ending the pandemic. Inadvertently, booster recommendations further polarized non-vaccinated participants, augmenting their skepticism of the original dosages' efficacy or necessity and intensifying their distrust of the government. The findings illuminate the need for adjusting vaccination promotions to better tailor communications (e.g., distinguishing its benefits from the first vaccine and emphasizing the continued risk of COVID-19 spread). Future researchers should further explore the vaccine-accepting-yet-booster-hesitant groups' motivations and risk perceptions to reduce booster rejection.
RESUMEN
Researchers established that parental vaccination status often predicts that of their children, but a limited number of studies have examined factors influencing dyadic concordance or discordance (i.e., same or different vaccination status or intent for both members). We investigated how child versus parent age as well as parents' perceptions of their respective friends' immunization behavior impacted un/vaccinated parents' decisions regarding vaccinating their child. An online survey obtained the COVID-19 vaccination status and views of 762 parents of 5-17-year-old children. More than three-quarters of all dyads were concordant; 24.1% of vaccinated parents would not vaccinate their child, with greater hesitancy for younger children and among younger or less educated parents. Children of vaccinated parents and of parents who thought most of their child's friends were vaccinated were 4.7 and 1.9 times, respectively, more likely to be vaccinated; unvaccinated parents were 3.2 times more likely to accept the vaccine for their child if they believed most of their friends would vaccinate their children. Further, parents who reported that most of their friends were vaccinated were 1.9 times more likely to have obtained the vaccine themselves, illustrating the influence of social norms. Regardless of their own vaccination status, parents of unvaccinated children were more likely to be politically conservative. If communities or circles of friends could achieve or convey a vaccinated norm, this might persuade undecided or reluctant parents to vaccinate their children. Future research should examine the effects of community behavior and messages highlighting social norms on pediatric vaccine uptake.
RESUMEN
OBJECTIVES: To assess the efficacy of using concurrent partial mastectomy and reduction mammoplasty for resection of a wide range of tumor sizes and compare oncologic outcomes and postoperative complications on the basis of tumor size. BACKGROUND: Although tumor size greater than 4 cm has been considered an indication for undergoing a mastectomy, this dictum may not apply in women with breast hypertrophy, where the ratio of tumor size to breast size may still permit breast conservation. We wished to evaluate whether an approach combining partial mastectomy with reduction mammoplasty could provide a safe oncologic procedure with immediate breast reconstruction that could technically be applied even for large (>4 cm) lesions. METHODS: A retrospective review of all patients undergoing partial mastectomy and concurrent reduction mammoplasty performed at our institution from 2000 to 2009. Clinical characteristics at presentation, pathologic data, and follow-up data were collected and analyzed. RESULTS: Eighty-five consecutive simultaneous partial mastectomy/reduction mammoplasty procedures were performed in 79 patients. Average tumor size was 2.8 cm for ductal carcinoma in situ (0.05-17.0 cm), 2.4 cm for invasive ductal carcinoma (IDC) (0.2-8.9 cm), 3.5 cm for lobular carcinoma (1.6-8.0 cm), and 5.7 cm for phyllodes tumors (3.7-7.6 cm). Twenty-five of 85 tumors (29.4%) were larger than 4 cm. Distribution for stage 0, I, II, III, and IV disease was 15, 12, 35, 19, and 2 tumors respectively, with an additional 2 phyllodes tumors. Median follow-up was 39 months (10-130 months). Seventy-five patients (94.9%) achieved successful breast conservation, whereas 4 patients (5.1%) went on to completion mastectomy. Thirteen patients (16.4%) required 1 reexcision to achieve clear margins, and 2 (2.5%) required multiple reexcisions. Two patients had a local recurrence during the follow-up period, one of whom underwent reexcision and the other underwent mastectomy. The overall complication rate was 14.1%, which included 4 major complications (4.7%) requiring an unplanned return to the operating room and need for hospital readmission, and 8 minor wound-related complications (9.4%). Neither recurrence nor complication rates were increased in patients with tumors greater than 4 cm when compared with tumors less than or equal to 4 cm. CONCLUSIONS: A partial mastectomy with concurrent reduction mammoplasty technique is a viable option for breast conservation even for larger tumors, combining a safe oncologic procedure with excellent cosmesis. A combined effort between breast surgeons and reconstructive surgeons has a high probability of success with low recurrence rates. In carefully selected patients, this approach may be preferable to mastecomy and breast reconstruction, particularly when postmastectomy radiation therapy is anticipated.

Interval cancers (ICs), defined as cancers detected between regular screening mammograms, have been shown to be of higher grade, larger size, and associated with lower survival, compared with screen-detected cancers (SDCs) and comprise 17% of cancers from population-based screening programs. We sought to determine the frequency of ICs in a study of locally advanced breast cancers, the I-SPY 1 TRIAL. Screening was defined as having a mammogram with 2 years, and the proportion of ICs at 1 and 2 years was calculated for screened patients. Differences in clinical characteristics for ICs versus SDCs and screened versus non-screened cancers were assessed. For the 219 evaluable women, mean tumor size was 6.8 cm. Overall, 80% of women were over 40 and eligible for screening; however, only 31% were getting screened. Among women screened, 85% were ICs, with 68% diagnosed within 1 year of a previously normal mammogram. ICs were of higher grade (49% vs. 10%) than SDCs. Among non-screened women, 28% (43/152) were younger than the recommended screening age of 40. Of the entire cohort, 12% of cancers were mammographically occult (MO); the frequency of MO cancers did not differ between screened (11%) and non-screened (15%). ICs were common in the I-SPY 1 TRIAL suggesting the potential need for new approaches beyond traditional screening to reduce mortality in women who present with larger palpable cancers.

Health equity has grown in prominence during the pandemic. Racial disparities in COVID-19 infections and vaccine hesitancy (differences up to 26%) have generated concerns, research, and interventions with less-than-satisfactory results. Two longitudinal national surveys in the U.S. revealed previously overlooked patterns in the changes of COVID-19 vaccination intention across race/ethnicity. While White vaccine acceptance bounced back to the March 2020 level (65%) a year later, minority (except Asians) responses continued to lag and fluctuated with greater volatility. Though Hispanics' refusal aligned more with Blacks, the ratio of Hispanics willing to vaccinate was similar to Whites, even intermittently went above. Further, the magnitude and direction of changes varied by race at specific times (e.g., launch of Operation Warp Speed, reports of high vaccine efficacy in clinical trials or FDA approval), indicating subgroups react differently to events and thus require timely identification of driving factors for dynamic communications to encourage uptake. We also briefly reviewed the historical background of distrust in medicine and health authorities, including the Tuskegee Syphilis Study that led to the Belmont Report regulating human subject research and severe adverse reactions from the 1976 mass vaccination against the H1N1 swine flu. These examples, perpetuating inequity in the present healthcare system, and logistical barriers illustrate the contextual complexity and importance of instilling confidence in vaccines among the minority population.

The COVID-19 vaccine is widely available to adolescents in the U.S.; however, vaccine hesitancy poses a threat to full coverage. The literature shows that perceived risks and the presence or lack of motivators are determinants for vaccination decisions, yet research evidence from minors is scant. This study adopted the Protection Motivation framework to identify differences in these facilitators and compare the influence of internal and external motivators among American adolescents in COVID-19 vaccine uptake. A nationwide online survey analyzed 13−17-year-old teenagers' COVID-19 beliefs as well as present or potential reasons for accepting the vaccine. Of the 439 participants, 21.18% were not and did not plan to get vaccinated. Another 52.39% had at least one dosage, of which over three-quarters were internally motivated (whereas those unvaccinated were more likely to be externally motivated, X2 = 4.117, p = 0.042). In unvaccinated individuals, older adolescents reported slightly more internal motivators than younger adolescents (t = −2.023, p = 0.046). Internal motivation was associated with higher risk perception (r2 = 0.06651, p = 0.001), but risk perception had a stronger relationship with vaccination status (r2 = 0.1816, p < 0.001), with vaccinated individuals showing higher risk perception than those unvaccinated (mean difference = 0.42 on a scale of 1−4; t = −3.603, p < 0.001); the risk perception difference was even greater between hesitant and non-hesitant participants (mean difference = 0.63; t = −0.892, p < 0.001). The relationship was moderated by perceived knowledge, where the difference in risk perception between vaccination status was only significant for those with low perceived knowledge (f = 10.59, p = 0.001). Increasing awareness of disease risks and stressing internal motivators may be key to improving uptake in young people. Future research could delve deeper into risk perception formation of adolescents and why and how it differs across populations.
RESUMEN
Previous researchers have established the influence of social norms on vaccine behavior. However, little work has been performed contextualizing individuals' experience with these social factors and how they operate to persuade individuals' acceptance or refusal of a vaccine. We aimed to determine the mechanisms of familial and societal pressure or expectations that contribute to COVID-19 vaccine decision-making. We conducted four focus groups and eleven individual interviews (total n = 32) with participants from across the U.S. of different vaccination statuses. We identified three emergent themes: (1) Altruistic reasoning was particularly prevalent among initially hesitant late adopters-the desire to protect loved ones and others constituted a dominant motive, more powerful than protecting oneself. Vaccination was also reckoned as part of a joint effort to return to normal life; hence, it invoked a sense of responsibility or "obligation"; (2) expectation often became pressure; although most vaccinated participants stated that they respected others' choices, late adopters or unvaccinated participants perceived differently and felt rushed or "forced" into choosing, and many resented being "targeted" or "bullied"; (3) vaccination status became a new label, frequently dividing families, thus producing familial mandates, exclusions, or social stratifications. This caused sadness and feelings of isolation, along with the formation of a camaraderie among the excluded unvaccinated. A vaccine decision builds from the complexities of individuals' experiences and cultures. The vaccinated were not free of hesitancy nor were the unvaccinated all anti-vaxxers. Vigorous vaccine promotion successfully converted some undecided individuals but also fostered distrust of government; alarmingly, the push to receive the COVID-19 vaccine further triggered doubts about established vaccines. Communication strategies need to be developed and implemented carefully so as not to ostracize the unvaccinated community and strengthen their resistance.
RESUMEN
PURPOSE: To assess diagnostic performance of ACR TI-RADS in thyroid cancer detection and evaluate interobserver agreement among radiologists with lower interpreting experience. METHODS: Four radiologists retrospectively assessed 295 biopsied thyroid nodules from ultrasound studies performed between 2009 and 2019, blinded to histopathology. Diagnostic performance for cancer detection was determined individually, and interobserver agreement among four readers was evaluated with Fleiss kappa coefficient (ⱪ). RESULTS: 245 (83.1%) benign and 50 (16.9%) malignant nodules were evaluated. Diagnostic performance based on final TR level was consistent and without significant difference among four readers, with excellent sensitivity (≥98.0%) and negative predictive value (NPV) [≥94.4%] for TR levels 3 to 5. Diagnostic performance based on recommendation to biopsy has moderate sensitivity (≥62%) and high NPV (≥84.7%). Retrospective scoring with established ACR TI-RADS criteria would have substantially reduced the number of biopsies performed, with 63.2% of malignancy not biopsied meeting criteria for sonographic surveillance. Interobserver agreement on TI-RADS scoring for final TR level was fair (ⱪ = 0.39, 95% CI 0.32, 0.47), with substantial agreement for recommendation to biopsy (ⱪ = 0.64, 95% CI 0.58, 0.70). CONCLUSIONS: Substantial reduction in biopsy rate (up to 48%) would have been achieved using the ACR TI-RADS criteria, with 63% of malignancy not biopsied meeting criteria for sonographic surveillance. Interobserver agreement was fair for TI-RADS level scoring and substantial for recommendation to biopsy.

Abnormal adhesion of red blood cells to the endothelium has been linked to the pathophysiology of several diseases associated with vascular disorders. Various biochemical changes, including phosphatidylserine exposure on the outer membrane of red blood cells as well as plasma protein levels, have been identified as being likely to play a key role, but the detailed interplay between plasma factors and cellular factors remains unknown. It has been proposed that the adhesion-promoting effect of plasma proteins originates from ligand interaction, but evidence substantiating this assumption is often missing. In this work, we identified an alternative pathway by demonstrating that nonadsorbing macromolecules can also have a marked impact on the adhesion efficiency of red blood cells with enhanced phosphatidylserine exposure to endothelial cells. It is concluded that this adhesion-promoting effect originates from macromolecular depletion interaction and thereby presents an alternative mechanism by which plasma proteins could regulate cell-cell interactions. These findings should thus be of potential value for a detailed understanding of the pathophysiology of diseases associated with vascular complications and might be applicable to a wide range of cell-cell interactions in plasma or plasma-like media.

Rheumatoid arthritis (RA) patients face psychological hardship due to physical discomfort, disabilities, and anxieties. Previous research indicated a bidirectional relationship and patient desire for emotional support from providers. This study examined lesser-understood RA experiences across the psychological and social contexts in relation to self-perception through the patients' expression of their struggles with these burdens. We conducted four semistructured focus groups and eleven interviews (total n = 31). A codebook was developed and refined through iterative transcript coding via NVivo-12. Four emerging themes were identified by inductive, thematic analysis: (1) the patients' healthy appearances were a myth, with subthemes revealing a conflict between an inclination to hide the disease and a desire for validation, while feeling embarrassed by symptom manifestations and disappointment at withdrawal from social interactions; (2) an identity crisis due to diminished functionality, autonomy, and sense of self; (3) RA constantly occupied the mind, as its unpredictability dictated daily schedules and altered plans; and (4) the disease's chronic nature influenced personal outlook to worry about or accept the uncertainty. Even with effective treatment, the invisibility of the disease, the fear and anticipation of flare-ups, and identity clashes caused emotional distress. The insights offer a different perspective on personalized medicine, complementing clinical treatments based on genetic or biomarker profile. For patient-centered holistic care, education is needed to prompt both patients and providers to discuss psychological issues for more customized, integrated interventions. The findings can help inform healthcare teams and families in recognizing and supporting these physical-psychological intertwined experiences, thereby ameliorating patients' wellbeing.
