Resilience and distress among adolescents and young adults receiving hematopoietic cell transplantation: The Promoting Resilience in Stress Management randomized trial.

BACKGROUND: Adolescents and young adults (AYAs) receiving hematopoietic cell transplantation (HCT) are at high risk of poor psychosocial health. This study aimed to determine whether the Promoting Resilience in Stress Management (PRISM) intervention mitigated these risks during the first 6 months posttransplant. METHODS: This multisite, parallel, randomized trial was conducted from April 2019 to March 2023. Eligible AYAs were aged 12-24 years, English speaking, and within 1 month of HCT for cancer or cancer predisposition syndrome. They were assigned 1:1 to PRISM (a brief, skills-based intervention targeting "resilience resources" [stress management, goal setting, cognitive reframing, and meaning making]) or usual care (UC). Outcomes included total symptoms of depression and anxiety (Hospital Anxiety and Depression Scale; primary outcome), hope (Snyder Hope Scale), resilience (10-item Connor-Davidson Resilience Scale), and health-related quality of life (HRQOL; Pediatric Quality of Life Inventory Cancer Module). Analyses leveraged multivariable linear regressions; exploratory analyses assessed the influence of baseline depression or anxiety. RESULTS: Of 94 enrolled and randomized AYAs, the mean age was 16.7 years (SD, 4.2); 43 (46%) were female, 56 (60%) were non-Hispanic White, 22 (23%) were Hispanic, and nine (10%) were Black. Most (77%) had leukemia. Of n = 50 randomized to PRISM and n = 44 to UC, 37 (74%) and 33 (73%) completed all study procedures, respectively. In intention-to-treat analyses, PRISM did not affect 6-month depression and anxiety (ß = -1.1; 95% CI, -3.7 to 1.5), hope (ß = 0.83; 95% CI, -3.3 to 4.9), resilience (ß = -0.01; 95% CI, -3.0 to 3.0), or HRQOL (ß = 1.5; 95% CI, -4.7 to 7.9). Among AYAs with preexisting anxiety or depression, PRISM recipients reported greater 6-month improvements in hope (score change, +3.71; SD, 6.9) versus UC recipients (score change, -2.76; SD, 6.5) (p = .04). CONCLUSIONS: Resilience coaching did not influence outcomes in this sample. Exploratory findings suggest it may be more effective when directed toward those with concurrent distress.

Nano copper in the diet of laying quails: productive performance, metabolism, and tissue concentration.

The study evaluated the use of nano copper in semi-purified diets for laying quails and its effect on performance, metabolic state, and bioavailability. A total of 160 (180-days-old) quails were distributed in a completely randomized design, in a 3x3+1 factorial. The copper sources used were copper sulfate, copper oxide, and nano copper oxide, at levels of 200, 400, and 800 ppm each, totaling nine treatments plus a negative control (with no copper inclusion). The following variables were determined: weight gain, feed intake, egg production, egg weight, hemoglobin, hematocrit, Cu in the tissues and Cu bioavailability. Data were subjected to analysis of variance at 5% probability. The effect of sources and levels, as well as the interaction between the factors were evaluated. When interaction was observed, the effect of sources was evaluated separately by the Tukey's test and the effect of levels by regression, both at 5% probability. Copper nano oxide can be used at up to 800 ppm in the diet of laying quails without altering the productive performance, and with higher bioavailability than conventional copper oxide. Hemoglobin increases with the inclusion of 200 and 400 ppm of nano copper oxide and the hematocrit with 400 ppm.

Key Psychosocial Health Outcomes and Association With Resilience Among Patients With Adult Congenital Heart Disease.

BACKGROUND: Adult congenital heart disease (ACHD) can negatively impact quality of life (QOL). Strengthening resilience may improve this and other psychosocial outcomes important for living a meaningful life. OBJECTIVES: The purpose of this study was to describe resilience and key psychosocial health outcomes in ACHD and evaluate the associations between resilience and these outcomes. METHODS: We conducted a prospective cohort study of outpatients with moderate or complex ACHD between May 2021 and June 2022. Participants completed surveys at baseline and 3 months, evaluating resilience (Connor-Davidson Resilience Scale-10), health-related QOL (EQ5D-3L, linear analog scale), health status (Euroqol visual analog scale), self-competence (Perceived Competence Scale), and psychological symptom burden (Hospital Anxiety and Depression Scale) and distress (Kessler-6). RESULTS: The mean participant age (N = 138) was 41 ± 14 years, 51% were female, and 83% self-identified as non-Hispanic White. ACHD was moderate for 75%; 57% were physiologic class B. Mean baseline resilience score (Connor-Davidson Resilience Scale-10) was 29.20 ± 7.54. Participants had relatively good health-related QOL, health status, and self-competence, and low psychological symptom burden and distress. Higher baseline resilience was associated with better values of all outcomes at 3 months (eg, 1 point higher resilience was associated with 0.92 higher linear analog scale; 95% CI: 0.52-1.32) with or without adjustment for demographics. After further adjusting for the baseline psychosocial measure, only the association between resilience and QOL measures at 3 months remained statistically significant. CONCLUSIONS: Resilience is positively associated with health-related QOL for outpatients with moderate or complex ACHD, though relationships are small in magnitude. Study findings can guide the application of resilience-building interventions to the ACHD population.

The Purpose, Process, and Advancement of Forensic Nursing Standards.

BACKGROUND: To strengthen the nation's use of forensic science and advance professional practice, forensic practitioners and scientists in the Organization of Scientific Area Committees (OSAC) develop standards in forensic science. The Forensic Nursing Subcommittee was created by OSAC in 2021 to develop standards that improve patient outcomes through delivery of consistent practice guidelines, evidence-based techniques for preservation of evidence, and accurate representation of practice and examination findings. PURPOSE: The purpose of this article is to relate the history of forensic science standard development in the United States, discuss the rationale for forensic nursing standards, and describe the standards development process. In this article, we provide an overview of OSAC and the OSAC Forensic Nursing Subcommittee. We discuss how forensic nurses can be involved in the development and advancement of standards that define minimum requirements, best practices, and evidence-based protocols to ensure reliable and reproducible outcomes. IMPLICATIONS FOR FORENSIC NURSES: The development of forensic nursing standards is an important step in advancing the profession. It is critical that forensic nurses are actively involved in the standards development process, which includes volunteering to serve on the OSAC Forensic Nursing Subcommittee or a forensic nursing standards development organization, providing input into standards drafts during the public comment period, and implementing approved standards into practice.

Ethnic Identity Protects and Internalized Racism Harms Health and Coping in Asian Americans Following COVID-19 Discrimination: A Mixed-Methods Study.

Mechanisms underlying the link between COVID-19 anti-Asian racial discrimination and psychological health are underexplored. This mixed-methods study examined the moderating effects of ethnic identity and internalized racism on the relationship between COVID discrimination and behavioral health outcomes among Asian Americans. We hypothesized that individuals with lower ethnic identity and higher internalized racism levels would demonstrate more adverse outcomes, including worsened psychological trauma and identity-avoidant behaviors, post-discrimination. Asian American participants (N = 215) responded to a Qualtrics survey, including qualitative and quantitative questions on COVID-related racism experiences, ethnic identity, internalized racism, trauma, and other subsequent effects. For qualitative analysis, participants were sorted into four subgroups defined by low- and/or high-ethnic identity and internalized racism scores, and we explored themes in participant reports of identity-related coping effects after racism. We additionally used hierarchical multiple regression analyses to quantitatively assess the moderating impact of ethnic identity and internalized racism on the relationship between COVID discrimination and trauma. Analyses revealed no moderating effects from the two identity variables. However, qualitative analyses identified themes of identity-promoting and identity-avoidant behavioral responses, and moderation analyses revealed that ethnic identity had a main effect on mitigating racial trauma, while internalized racism exacerbated both racial trauma and PTSD levels. This study identified ethnic identity and internalized racism as underlying causes to behavioral health outcomes for Asian Americans. Results offer mental health providers serving Asian clients insight into identity-related influences to help optimize culturally appropriate interventions and support initiatives of identity promotion to foster community engagement for this population.

The Culturally Infused Curricular Framework (CICF) for Suicide Prevention Trainings.

Although suicide prevention trainings (SPT) have been a standard approach for suicide prevention for years, researchers have noted a need for more clarity in the definition of core competencies for SPTs, particularly in the areas of diversity and culture. Recent research has identified key theoretically- and empirically-based cultural considerations for suicide prevention, but translation is needed to infuse these standards for culture-related competencies into SPTs. This study performed a systematic literature review with a thematic synthesis analytic approach to establish a set of curricular guidelines for infusion of cultural considerations into SPTs. The study also examined the extent to which existing community trainings already incorporate cultural components. Based on the thematic synthesis of 39 SPT studies from 2010 to 2020 and seminal reviews of the cultural and suicide literature, results identified three overarching categories of cultural curricular competencies (suicide knowledge and awareness, suicide intervention skills, and curriculum delivery) and 14 core cultural curricular subthemes for community trainings (e.g., culturally informed risk factors and warning signs, systemic inequities, etc.). These three categories with 14 core cultural curricular competencies comprise the Culturally Infused Curricular Framework (CICF) for Suicide Prevention Trainings. The majority of trainings (62%) included five or less out of 14 total possible core cultural competencies in their training curricula, pointing to insufficient integration of cultural components in existing community trainings. This study's research-based guideline establishes a culture-inclusive framework to strengthen content and approach of community trainings and suicide prevention across cultural groups.

Level of self-efficacy among skill-based allied health students in the University of Santo Tomas-Enriched Virtual Mode of learning: A cross-sectional study.

Background: Self-efficacy expresses a learner's perception of how well they can do in the online academic setting. Although students' academic successes can be measured by online learning self-efficacy, there is a scarcity of evidence targeted toward allied health students. Objective: The primary aim of this study is to determine the level of online self-efficacy among students from skill-based allied health programs. The secondary aim is to correlate online self-efficacy with age, sex, year level, and program of the students. Methods: This cross-sectional analytic study utilized the Online Learning Self-Efficacy Scale (OLSE) to determine students' level of self-efficacy via a survey conducted with students who underwent the Enriched Virtual Mode of learning. Descriptive statistics was used to characterize the study participants, describe the level of self-efficacy, and compare the subscales of OLSE. Inferential statistics using Spearman's rho was performed to determine the correlation. Results: A total of 117 respondents with a mean age ± SD of 20.59 ± 0.11 years old, predominantly female (71%) were included in the study. The students from allied health programs had an online self-efficacy overall mean score of 3.83 (SD=0.05; range 2.64-5.00) with the use of technology subscales weighted the highest mean score (4.24). Females have a higher average OLSE score (M=3.92, SD=0.05) compared to males. Significant correlation was found between OLSE scores to sex (r=0.260, p=0.005) and year level (r=-0.199, p=0.031) while nonsignificant correlation was found between OLSE scores to the program (r=-0.048, p=0.604) and age (r=-0.123, p=0.185). Conclusion: Students of allied health programs generally have a very good level of online self-efficacy. This study assists educators in developing proactive strategies and approaches to promote students' self-confidence across all domains and encourage them to adopt a dynamic remote learning-based approach. Educational institutions should use this opportunity to assess how well they have implemented remote learning to ensure educational continuity, especially in times of crisis.

Meaning-Making Among Parents of Children With Severe Neurologic Impairment in the PICU.

BACKGROUND AND OBJECTIVES: Parents and family caregivers of children with severe neurologic impairment (SNI) experience many stressors, especially during their child's critical illness. This study aimed to examine parent experiences around the time of their child's PICU care to explore ways parents make meaning in relation to these stressors. METHODS: This qualitative study of data from a single center in the United States followed Consolidated Criteria for Reporting Qualitative Research guidelines. One to one semistructured interviews queried parents' psychosocial well-being around the time of their child's PICU care. Eligible participants had a child with an SNI condition for >3 months admitted to the PICU for >24 hours with an expected length of stay >1 week. RESULTS: Data were analyzed by a research team with expertise in palliative care, psychology, critical care, and qualitative methods. Fifteen family caregivers of 15 children participated. Children were a median of 8 years old (interquartile range 4-11.5) and 80% (n = 12) had congenital/genetic conditions. Parent/family caregivers were a median age of 39 years old (interquartile range 36-42.5); 20% (n = 3) self-identified as fathers and 47% (n = 7) as having to a minority racial background. Parents discussed ongoing meaning-making that occurred through domains of comprehension and purpose, and themes of understanding of other people and the world around them. Subthemes focused on appreciation/acceptance, adaptability/accountability, valuing all lives, and learning/teaching about their child. CONCLUSIONS: Meaning-making may be an opportunity for support in the PICU among parents/family caregivers of children with SNI.

Prevalence of and Factors Associated with Financial Toxicity After Pancreatectomy and Gastrectomy.

BACKGROUND: Financial toxicity (FT) refers to the adverse impact of cancer treatment costs on patients' experiences, potentially leading to poor adherence to treatment and outcomes. However, the prevalence of FT among patients undergoing major upper gastrointestinal cancer operations, as well as factors associated with FT, remain unclear. METHODS: We conducted a cross-sectional study by sending the Comprehensive Score for financial Toxicity (COST) survey and Surgery-Q (a survey specifically developed for this study) to patients who underwent gastrectomy or pancreatectomy for malignant disease at our institution in 2019-2021. RESULTS: We sent the surveys to 627 patients and received responses from 101 (16%) patients. The FT prevalence (COST score <26) was 48 (48%). Patients likely to experience FT were younger than 50 years of age, of non-White race, earned an annual income <$75,000, and had credit scores <740 (all p < 0.05). Additionally, longer hospital stay (p = 0.041), extended time off work for surgery (p = 0.011), and extended time off work for caregivers (p = 0.005) were associated with FT. Procedure type was not associated with FT; however, patients who underwent minimally invasive surgery (MIS) had a lower FT probability (p = 0.042). In a multivariable analysis, age <50 years (p = 0.031) and credit score <740 (p < 0.001) were associated with high FT risk, while MIS was associated with low FT risk (p = 0.024). CONCLUSIONS: Patients with upper gastrointestinal cancer have a major risk of FT. In addition to predicting the FT risk before surgery, facilitating quicker functional recovery with the appropriate use of MIS is considered important to reducing the FT risk.

Ruminal modulator additive effect of Stryphnodendron rotundifolium bark in feedlot lambs.

The study aimed to evaluate the inclusion effects of Stryphnodendron rotundifolium (barbatimão) extracts in substitution of the lasalocid sodium on the ingestive behaviour, intake, ruminal parameters, and digestibility of feedlot lambs. Twenty-four pantaneiro lambs were used, with an average age of 150 ± 4.59 days and an initial body weight of 21.2 ± 3.63 kg. The lambs were distributed in three treatments in an experimental design with randomized blocks. The treatments correspond to the additive supplements: LAS (0.019 g of lasalocid sodium/lamb/d); DGB (1.50 g of barbatimão dried ground bark/lamb/d); DHE (0.30 g of barbatimão dry hydroalcoholic extract/lamb/d). The DHE increased 59.74 min in the time spent for ingestion per day, resulting in an efficiency reduction of dry matter (DM) ingestion (127 g of DM/h of feed). There was a reduction of 1.8 mg/dL in the ammoniacal nitrogen concentration with extract supplementation compared to LAS. The DGB reduced total volatile fatty acids by 48.9% compared to the control treatment. The inclusion of barbatimão extracts (DGB and DHE) reduced 12.05% of ruminal butyrate content. The supplementation of barbatimão extracts replacing lasalocid sodium in the diet of feedlot lambs did not affect intake and caused small changes on ingestive behaviour.

Online Educational Resources for Youth Living With Type 1 Diabetes Transitioning to Adult Care: An Environmental Scan of Canadian Content.

OBJECTIVES: There are many educational resources for adolescents and young adults living with type 1 diabetes; however, it is unknown whether they address the breadth of topics related to transition to adult care. Our aim in this study was to collect educational resources relevant to Canadian youth and assess their quality and comprehensiveness in addressing the knowledge necessary for youth to prepare for interdependent management of their diabetes. METHODS: We conducted an environmental scan, a systematic assessment and analysis, of online education resources in English and French relevant to Canadian youth living with type 1 diabetes. Resources were screened using an open education resource evaluation grid and relevant resources were mapped to the Readiness for Emerging Adults with Diabetes Diagnosed in Youth, a validated diabetes transition readiness assessment tool. RESULTS: From 44 different sources, 1,245 resources were identified and, of these, 760 were retained for analysis. The majority were webpages (50.1%) and downloadable PDFs (42.4%), and 12.1% were interactive. Most resources covered Diabetes Knowledge (46.0%), Health Behaviour (23.8%), Insulin and Insulin Pump Management (11.8% and 8.6%, respectively), and Health-care System Navigation (9.7%). Topic areas with the fewest resources were disability accommodations (n=5), sexual health/function (n=4), and locating trustworthy diabetes resources (n=3). CONCLUSIONS: There are many resources available for those living with type 1 diabetes preparing to transition to adult care, with the majority pertaining to diabetes knowledge and the least for navigation of the health system. Few resources were available on the topics of substance use, sexual health, and reproductive health. An interactive presentation of these resources, as well as a central repository to house these resources, would improve access for youth and diabetes care providers during transition preparation.

Exploring Experiences of Traumatic Microaggressions Toward Surgeons and Surgical Residents.

INTRODUCTION: Studies have suggested that experiences of gender and racial discrimination are widespread among surgeons and surgical residents. This study examines the relationship between experienced microaggressions and traumatic stress. METHODS: A one-time, deidentified survey was distributed over email to academic surgical societies. The survey consisted of 35 items including questions on prevalence of microaggressions, perceived job impacts as well as a shortened version of the Trauma Symptoms of Discrimination Scale. Chi-square tests and an independence test for trends were utilized to determine significance. RESULTS: We collected data from 130 participants with majority (81%) having experienced microaggressions in the workplace. On measures of worry (P < 0.001), avoidance (P = 0.012), anxiety (P = 0.004), and trouble relaxing (P = 0.002), racial/ethnic minority surgeons and trainees demonstrated significantly higher scores. With perceived job impacts, significant agreement was seen with occurrences of working harder to prove competence (P = 0.005), gaining patient confidence (P < 0.001), reduced career satisfaction (P = 0.011), work-related negative talk (P = 0.018), and burnout at work due to microaggressions (P = 0.019). Among participants who underwent behavioral modifications, female surgeons were more likely to change their nonverbal communication styles (P < 0.001) and spend more time with patients (P < 0.001). CONCLUSIONS: Experiences of microaggressions are associated with increased anxiety-related trauma symptoms in racial/ethnic minority surgeons and surgical trainees. Additionally, these experiences of microaggression can influence job satisfaction, burnout, career perceptions and workplace behaviors. As the field of surgery becomes more diverse, this study contributes to growing awareness of the role of implicit discrimination in the attrition and retention of racial/ethnic minority surgeons and female surgeons.

Pre-hospital ECPR in an Australian metropolitan setting: a single-arm feasibility assessment-The CPR, pre-hospital ECPR and early reperfusion (CHEER3) study.

INTRODUCTION: Survival from refractory out of hospital cardiac arrest (OHCA) without timely return of spontaneous circulation (ROSC) utilising conventional advanced cardiac life support (ACLS) therapies is dismal. CHEER3 was a safety and feasibility study of pre-hospital deployed extracorporeal membrane oxygenation (ECMO) during cardiopulmonary resuscitation (ECPR) for refractory OHCA in metropolitan Australia. METHODS: This was a single jurisdiction, single-arm feasibility study. Physicians, with pre-existing ECMO expertise, responded to witnessed OHCA, age < 65 yrs, within 30 min driving-time, using an ECMO equipped rapid response vehicle. If pre-hospital ECPR was undertaken, patients were transported to hospital for investigations and therapies including emergent coronary catheterisation, and standard intensive care (ICU) therapy until either cardiac and neurological recovery or palliation occurred. Analyses were descriptive. RESULTS: From February 2020 to May 2023, over 117 days, the team responded to 709 "potential cardiac arrest" emergency calls. 358 were confirmed OHCA. Time from emergency call to scene arrival was 27 min (15-37 min). 10 patients fulfilled the pre-defined inclusion criteria and all were successfully cannulated on scene. Time from emergency call to ECMO initiation was 50 min (35-62 min). Time from decision to ECMO support was 16 min (11-26 min). CPR duration was 46 min (32-62 min). All 10 patients were transferred to hospital for investigations and therapy. 4 patients (40%) survived to hospital discharge neurologically intact (CPC 1/2). CONCLUSION: Pre-hospital ECPR was feasible, using an experienced ECMO team from a single-centre. Overall survival was promising in this highly selected group. Further prospective studies are now warranted.

Efficacy of Arthrocentesis with and Without Sodium Hyaluronate Injection for Temporomandibular Joint Disorders: A Comparative Study.

Aim: To evaluate the efficacy of arthrocentesis with and without sodium hyaluronate injection for internal derangement of temporomandibular joint. Materials and Methods: Patients with clinically and radiographically confirmed cases of temporomandibular joint disorders were enrolled for this study. 20 patients were randomly allocated into two groups for arthrocentesis of TMJ with 10 patients in each group. In group 1, patients were treated with TMJ arthrocentesis followed by sodium hyaluronate injection, and in group 2, patients were treated with arthrocentesis alone. All the patients were treated under local anaesthesia. The patients were followed up at 1st week, 2nd week, 4th week and 12th week post operatively for maximum mouth opening, lateral mandibular movements, pain at rest and on mastication and the subjective efficacy of the treatment. Results: By the end of twelfth week follow up, the mean mouth opening showed significant improvement in group 1, the right and left lateral movements showed better results in group 1 than in group 2, pain at rest and pain on mastication were mild in both the groups with subjective efficacy good in group 1 and moderate in group 2. Conclusion: This study suggested that TMJ arthrocentesis with sodium hyaluronate injection had better clinical outcome compared to TMJ arthrocentesis alone for TMJ disorders.

Relationships between spirituality and mental stress in people living with HIV in China: A cross-sectional study.

There are limited reports on the relationship between spirituality and mental stress in PLWH in China, who may be subject to anti-religious pressures from the government. In this study, we aimed to understand whether spirituality influences Chinese PLWH's mental stress and, if so, at what level. We recruited 200 PLWHs from Beijing's Ditan Hospital to complete a cross-sectional survey inquiring about their practice of spirituality as well as their level of mental stress. The study found that PLWH who presented with a mid-level of spirituality have the highest mental stress when compared to those who have a low level of spiritual beliefs or a high level of spiritual beliefs. This study points to the utility of healthcare providers taking PLWH's potential spirituality into consideration, perhaps in particular for those with a moderate level of spirituality, in order to provide the most comprehensive care possible.

Navigating Stress in the Pediatric Intensive Care Unit Among Parents of Children with Severe Neurological Impairment.

CONTEXT: Children with severe neurological impairment (SNI) make up nearly 50% of pediatric intensive care unit (PICU) admissions, yet little is known about their family caregiver experiences. OBJECTIVE: To examine how parents and family caregivers of children with SNI navigate stress during PICU admissions. METHODS: This qualitative single-center study used content and thematic networks analysis to evaluate data from 1:1 semistructured interviews conducted around the time of PICU discharge with parents and family caregivers of children with SNI to examine ways they navigate stress. Proportions of participants reporting each theme and subtheme were calculated. RESULTS: Fifteen parents/family caregivers of 15 children with SNI participated. Children were a median of 8 years old (range 1-21 years) and the majority had congenital/chromosomal conditions leading to their neurologic condition (80%, n = 12). 20% of participants were fathers (n = 3) and 45% (n = 7) reported identifying as having a minority racial background. Themes included 1) self-activation, and 2) letting go and the majority (80%, n = 12) of parents reported using both self-activation and letting go strategies. Within each of these themes, 5 subthemes illustrated ways parents navigate stress. The most reported subthemes were advocating and showing up (53%, n = 8) and being supported by compassionate clinicians (67%, n = 10). Themes/subthemes were used to create recommended language to guide clinicians in supporting parents. CONCLUSION: Parents and family caregivers of children with SNI employ various ways to navigate stress in the PICU. Themes from this study can be used to develop interventions that meet the psychosocial needs of parents and family caregivers of children with SNI during highly stressful times.

Health disparities affecting persons living with HIV and using substances in China.

Health disparities affecting persons living with HIV (PLWH) as well as those affecting individuals who use substances have been documented in China. However, health status and outcomes within the intersectional population of those who both live with HIV and use substances is not well understood. One hundred and sixty-nine PLWH receiving care in China completed surveys assessing HIV-clinical factors, substance use, and HIV-related physical health symptoms. We tested associations between substance use and health symptoms using multivariate logistic and ordinal regressions. Using one substance over the past week was associated with greater maximal severity of physical symptoms (p < .01); using two or more substances in the past week was associated with both increased total physical symptom severity (p < .05) and a dosage response in increased maximal severity (p < .01). Findings highlight the need for providers to address substance use for comprehensive care of PLWH to improve overall wellbeing.

N-of-1 trials: The epitome of personalized medicine?

Observational studies are notoriously susceptible to bias, and parallel-group randomized trials are important to identify the best overall treatment for eligible patients. Yet, such trials can be expected to be a misleading indicator of the best treatment for some subgroups or individual patients. In selected circumstances, patients can be treated in n-of-1 trials to address the inherent heterogeneity of treatment response in clinical populations. Such trials help to accomplish the ultimate goal of all biomedical research, to optimize the care of individual patients.
