RESUMEN
BACKGROUND: Recent data suggest that complications and death from coronavirus disease 2019 (Covid-19) may be related to high viral loads. METHODS: In this ongoing, double-blind, phase 1-3 trial involving nonhospitalized patients with Covid-19, we investigated two fully human, neutralizing monoclonal antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein, used in a combined cocktail (REGN-COV2) to reduce the risk of the emergence of treatment-resistant mutant virus. Patients were randomly assigned (1:1:1) to receive placebo, 2.4 g of REGN-COV2, or 8.0 g of REGN-COV2 and were prospectively characterized at baseline for endogenous immune response against SARS-CoV-2 (serum antibody-positive or serum antibody-negative). Key end points included the time-weighted average change in viral load from baseline (day 1) through day 7 and the percentage of patients with at least one Covid-19-related medically attended visit through day 29. Safety was assessed in all patients. RESULTS: Data from 275 patients are reported. The least-squares mean difference (combined REGN-COV2 dose groups vs. placebo group) in the time-weighted average change in viral load from day 1 through day 7 was -0.56 log10 copies per milliliter (95% confidence interval [CI], -1.02 to -0.11) among patients who were serum antibody-negative at baseline and -0.41 log10 copies per milliliter (95% CI, -0.71 to -0.10) in the overall trial population. In the overall trial population, 6% of the patients in the placebo group and 3% of the patients in the combined REGN-COV2 dose groups reported at least one medically attended visit; among patients who were serum antibody-negative at baseline, the corresponding percentages were 15% and 6% (difference, -9 percentage points; 95% CI, -29 to 11). The percentages of patients with hypersensitivity reactions, infusion-related reactions, and other adverse events were similar in the combined REGN-COV2 dose groups and the placebo group. CONCLUSIONS: In this interim analysis, the REGN-COV2 antibody cocktail reduced viral load, with a greater effect in patients whose immune response had not yet been initiated or who had a high viral load at baseline. Safety outcomes were similar in the combined REGN-COV2 dose groups and the placebo group.

BACKGROUND: In the phase 1-2 portion of an adaptive trial, REGEN-COV, a combination of the monoclonal antibodies casirivimab and imdevimab, reduced the viral load and number of medical visits in patients with coronavirus disease 2019 (Covid-19). REGEN-COV has activity in vitro against current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern. METHODS: In the phase 3 portion of an adaptive trial, we randomly assigned outpatients with Covid-19 and risk factors for severe disease to receive various doses of intravenous REGEN-COV or placebo. Patients were followed through day 29. A prespecified hierarchical analysis was used to assess the end points of hospitalization or death and the time to resolution of symptoms. Safety was also evaluated. RESULTS: Covid-19-related hospitalization or death from any cause occurred in 18 of 1355 patients in the REGEN-COV 2400-mg group (1.3%) and in 62 of 1341 patients in the placebo group who underwent randomization concurrently (4.6%) (relative risk reduction [1 minus the relative risk], 71.3%; P<0.001); these outcomes occurred in 7 of 736 patients in the REGEN-COV 1200-mg group (1.0%) and in 24 of 748 patients in the placebo group who underwent randomization concurrently (3.2%) (relative risk reduction, 70.4%; P = 0.002). The median time to resolution of symptoms was 4 days shorter with each REGEN-COV dose than with placebo (10 days vs. 14 days; P<0.001 for both comparisons). REGEN-COV was efficacious across various subgroups, including patients who were SARS-CoV-2 serum antibody-positive at baseline. Both REGEN-COV doses reduced viral load faster than placebo; the least-squares mean difference in viral load from baseline through day 7 was -0.71 log10 copies per milliliter (95% confidence interval [CI], -0.90 to -0.53) in the 1200-mg group and -0.86 log10 copies per milliliter (95% CI, -1.00 to -0.72) in the 2400-mg group. Serious adverse events occurred more frequently in the placebo group (4.0%) than in the 1200-mg group (1.1%) and the 2400-mg group (1.3%); infusion-related reactions of grade 2 or higher occurred in less than 0.3% of the patients in all groups. CONCLUSIONS: REGEN-COV reduced the risk of Covid-19-related hospitalization or death from any cause, and it resolved symptoms and reduced the SARS-CoV-2 viral load more rapidly than placebo.

OBJECTIVES: Clinicians report training deficits in advance care planning (ACP), including limits to their understanding of cultural/spiritual influences on patient decision-making and skills in interdisciplinary teamwork. This study describes Advance Directives-Live Action Simulation Training (AD-LAST), an interdisciplinary experiential and didactic training program for discussing ACP and end-of-life (EOL) care. AD-LAST highlights cultural/spiritual variations in medical decision-making. METHODS: Prospective educational cohort study with pre-post intervention survey. AD-LAST incorporated standard curricular tools for didactic and experiential training in ACP/EOL communication. Study conducted in an urban community teaching hospital in Queens, NY, one of the most diverse counties in the USA. Participants included physicians, house staff, nurses, therapists, and other disciplines. AD-LAST format was a one-day workshop. The morning focused on didactic teaching using widely available curricular tools. The afternoon involved experiential practice with standardized patient-actors. Pre-post intervention questionnaires assessed ACP operational knowledge and self-efficacy (i.e., self-confidence in skills) in ACP and EOL communication. Repeated measure ANOVAs evaluated changes from pretest to posttest in knowledge and self-efficacy. RESULTS: A total of 163 clinical staff participated in 21 AD-LAST training sessions between August 2015 and January 2019. Participants displayed a significant increase from pretest to posttest in total knowledge (p < 0.001), ACP procedural knowledge (p < 0.001), ACP communication/relationships knowledge (p < 0.001), and self-efficacy (p < 0.001). Knowledge and self-efficacy were not correlated and represented independent outcomes. Postprogram evaluations showed greater than 96% of participants were highly satisfied with AD-LAST, especially the opportunity to practice skills in real-time and receive feedback from members of other professional groups. SIGNIFICANCE OF RESULTS: AD-LAST, a multifaceted training program deployed in an interdisciplinary setting, is effective for increasing ACP knowledge and self-efficacy, including the capacity to address cultural/spiritual concerns. The use of standard tools facilitates dissemination. The use of case simulations reinforces learning.

BACKGROUND: The open-label RECOVERY study reported improved survival in hospitalized, SARS-CoV-2 seronegative patients treated with casirivimab and imdevimab (CAS + IMD). METHODS: In this phase 1/2/3, double-blind, placebo-controlled trial conducted prior to widespread circulation of Delta and Omicron, hospitalized COVID-19 patients were randomized (1:1:1) to 2.4â g or 8.0â g CAS + IMD or placebo, and characterized at baseline for viral load and SARS-CoV-2 serostatus. RESULTS: In total, 1336 patients on low-flow or no supplemental (low-flow/no) oxygen were treated. The primary endpoint was met in seronegative patients, the least-squares mean difference (CAS + IMD versus placebo) for time-weighted average change from baseline in viral load through day 7 was -0.28 log10 copies/mL (95% confidence interval [CI], -.51 to -.05; P = .0172). The primary clinical analysis of death or mechanical ventilation from day 6 to 29 in patients with high viral load had a strong positive trend but did not reach significance. CAS + IMD numerically reduced all-cause mortality in seronegative patients through day 29 (relative risk reduction, 55.6%; 95% CI, 24.2%-74.0%). No safety concerns were noted. CONCLUSIONS: In hospitalized COVID-19 patients on low-flow/no oxygen, CAS + IMD reduced viral load and likely improves clinical outcomes in the overall population, with the benefit driven by seronegative patients, and no harm observed in seropositive patients. CLINICAL TRIALS REGISTRATION: NCT04426695.
Lay Summary . Monoclonal antibody therapies that block the virus that causes COVID-19 (SARS-CoV-2) can prevent patients from being hospitalized. We hypothesized that these antibodies may also benefit patients who are already hospitalized with COVID-19. Therefore, we performed a study to determine if the monoclonal antibody combination of casirivimab and imdevimab (CAS + IMD) can decrease the amount of virus in the nose of hospitalized patients and prevent the disease from becoming more severe. The study, conducted from June 2020 to April 2021, found that CAS + IMD treatment reduced the amount of virus in these patients, and may reduce their chance of dying or needing a ventilator (a machine that helps patients breathe). Patients were examined in 2 groups: those whose immune systems, at the start of the study, had not produced their own antibodies to fight SARS-CoV-2 (seronegative patients); or those that had already produced their own antibodies (seropositive patients) at the start of the study. Seronegative patients benefited the most from CAS + IMD. No safety concerns related to CAS + IMD were observed. These results demonstrate that monoclonal antibody therapy can help hospitalized patients with COVID-19 and may decrease their chances of needing assistance to breathe or dying.

BACKGROUND: The revised 2018 ISN/RPS Classification System for lupus nephritis (LN) includes calculations for both activity index (A.I.) and chronicity index (C.I.). Unchanged were the thresholds of < 25%, 25-50%, and > 50% crescents to distinguish between mild, moderate, and severe activity/chronicity. We aimed to evaluate these thresholds for percent crescents in childhood-onset LN. METHODS: Eighty-six subjects < 21 years of age were enrolled from the Pediatric Glomerulonephritis with Crescents Registry, a retrospective multi-center cohort sponsored by the Pediatric Nephrology Research Consortium. Thresholds of 10%, 25%, and 50% for both cellular/fibrocellular and fibrous crescents were interrogated for primary outcomes of kidney failure, eGFR, and eGFR slope. RESULTS: Median age at time of initial biopsy was 14 years (range 1-21). Median follow-up time was 3 years (range 1-11). Cumulative incidence of kidney failure was 6% at 1 year and 10% at latest follow-up. Median eGFR slope was - 18 mL/1.73 m2/min (IQR - 51 to + 8) at 1 year and - 3 mL/min/1.73 m2/year (IQR - 19 to + 6) at latest follow-up. We found no difference in kidney failure at the proposed < 25% and 25-50% cellular crescents thresholds, and thus added a new provisional threshold of 10% that better predicted outcomes in children. Moreover, use of 10% and 25% thresholds for fibrous crescents showed a fourfold and sevenfold increase in risk of kidney failure. CONCLUSIONS: In children with crescentic LN, use of 10% and 25% thresholds for cellular crescents better reflects disease activity, while these thresholds for fibrous crescents better discriminates kidney disease outcomes.

OBJECTIVE: The objectives of this study were to develop and refine EMPOWER (Enhancing and Mobilizing the POtential for Wellness and Resilience), a brief manualized cognitive-behavioral, acceptance-based intervention for surrogate decision-makers of critically ill patients and to evaluate its preliminary feasibility, acceptability, and promise in improving surrogates' mental health and patient outcomes. METHOD: Part 1 involved obtaining qualitative stakeholder feedback from 5 bereaved surrogates and 10 critical care and mental health clinicians. Stakeholders were provided with the manual and prompted for feedback on its content, format, and language. Feedback was organized and incorporated into the manual, which was then re-circulated until consensus. In Part 2, surrogates of critically ill patients admitted to an intensive care unit (ICU) reporting moderate anxiety or close attachment were enrolled in an open trial of EMPOWER. Surrogates completed six, 15-20 min modules, totaling 1.5-2 h. Surrogates were administered measures of peritraumatic distress, experiential avoidance, prolonged grief, distress tolerance, anxiety, and depression at pre-intervention, post-intervention, and at 1-month and 3-month follow-up assessments. RESULTS: Part 1 resulted in changes to the EMPOWER manual, including reducing jargon, improving navigability, making EMPOWER applicable for a range of illness scenarios, rearranging the modules, and adding further instructions and psychoeducation. Part 2 findings suggested that EMPOWER is feasible, with 100% of participants completing all modules. The acceptability of EMPOWER appeared strong, with high ratings of effectiveness and helpfulness (M = 8/10). Results showed immediate post-intervention improvements in anxiety (d = -0.41), peritraumatic distress (d = -0.24), and experiential avoidance (d = -0.23). At the 3-month follow-up assessments, surrogates exhibited improvements in prolonged grief symptoms (d = -0.94), depression (d = -0.23), anxiety (d = -0.29), and experiential avoidance (d = -0.30). SIGNIFICANCE OF RESULTS: Preliminary data suggest that EMPOWER is feasible, acceptable, and associated with notable improvements in psychological symptoms among surrogates. Future research should examine EMPOWER with a larger sample in a randomized controlled trial.

BACKGROUND: Hispanics often have disparities at the end of life. They are more likely to die full code and less likely to have discussions regarding prognosis and do not resuscitate (DNR)/do not intubate (DNI), despite studies showing Hispanic values comfort over the extension of life. Barriers to patient-centered care include language,socioeconomic status and health literacy. CONTEXT: We evaluated the impact of palliative care (PC) consults on the change of code status and hospice referrals, comparing seriously ill Hispanic and non-Hispanic white patients. METHOD: A retrospective cohort study of all white and Hispanic patients referred to the PC service of a county hospital from 2006 to 2012. We evaluated ethnicity, language, code status at admission and after PC consult, and hospice discharge. Chi-squared tests were used to analyze characteristics among three groups: non-Hispanic white, English-speaking Hispanic, and Spanish-speaking Hispanic patients. RESULTS: Of 925 patients, 511 (55%) were non-Hispanic white, 208 (23%) were English-speaking Hispanic, and 206 (22%) were Spanish-speaking Hispanic patients. On admission, there was no statistically significant difference in code status among the three groups (57%, 64%, and 59% were full code, respectively, p = 0.5). After PC consults, Spanish-speaking Hispanic patients were more likely to change their code status to DNR/DNI when compared with non-Hispanic white and English-speaking Hispanic patients (44% vs. 32% vs. 28%, p = 0.05). Spanish-speaking Hispanic patients were more likely to be discharged to hospice when compared with English-speaking Hispanics and non-Hispanic whites (33%, 29%, and 23%, respectively, p = 0.04). SIGNIFICANCE OF RESULTS: Spanish-speaking Hispanic patients were more likely to change from full code to DNR/DNI compared with non-Hispanic white and English-speaking Hispanic patients, despite similar code status preferences on admission. They were also more likely to be discharged to hospice. PC consults may play an important role in helping patients to align their care with their values and may prevent unwanted aggressive interventions at the end of life.

Background: Tenofovir disoproxil fumarate (TDF) decreases bone mineral density (BMD). We hypothesized that vitamin D3 (VITD3) would increase BMD in youth receiving TDF. Methods: This was a randomized, double-blind, placebo-controlled trial of directly observed VITD3 vs placebo every 4 weeks for 48 weeks in youth aged 16-24 years with HIV, RNA load <200 copies/mL, taking TDF-containing combination antiretroviral therapy (TDF-cART) for ≥180 days. Participants (N = 214) received a daily multivitamin containing VITD3 400 IU and calcium 162 mg, plus monthly randomized VITD3 50000 IU (n = 109) or placebo (n = 105). Outcome was change from baseline to week 48 in lumbar spine BMD (LSBMD). Data presented are median (Q1, Q3). Results: Participants were aged 22.0 (21.0, 23.0) years, 84% were male, and 74% were black/African American. At baseline, 62% had 25-hydroxy vitamin D (25-OHD) <20 ng/mL. Multivitamin adherence was 49% (29%, 69%), and VITD3/placebo adherence 100% (100%, 100%). Vitamin D intake was 2020 (1914, 2168) and 284 (179, 394) IU/day, and serum 25-OHD concentration was 36.9 (30.5, 42.4) and 20.6 (14.4, 25.8) ng/mL at 48 weeks in VITD3 and placebo groups, respectively (P < .001). From baseline to week 48, LSBMD increased by 1.15% (-0.75% to 2.74%) in the VITD3 group (n = 99; P < .001) and 0.09% (-1.49% to 2.61%) in the placebo group (n = 89; P = .25), without between-group difference (P = .12). VITD3 group changes occurred with baseline 25-OHD <20 ng/mL (1.17% [-.82% to 2.90%]; P = .004) and ≥20 ng/mL (0.93% [-.26% to 2.15%]; P = .033). Conclusions: For youth taking TDF-cART, LSBMD increased through 48 weeks with VITD3 plus multivitamin, but not with placebo plus multivitamin, independent of baseline vitamin D status. Clinical Trials Registration: NCT01751646.

BACKGROUND: We aimed to define the relative importance of renal and endocrine changes in tenofovir disoproxil fumarate (TDF)-related bone toxicity. METHODS: In a study of daily TDF/emtricitabine (FTC) preexposure prophylaxis (PrEP) in human immunodeficiency virus (HIV)-uninfected young men who have sex with men, we measured changes from baseline in blood and urine markers of the parathyroid hormone (PTH)-vitamin D-fibroblast growth factor 23 (FGF23) axis, creatinine, and renal tubular reabsorption of phosphate (TRP). We explored the relationship of those variables to changes in bone mineral density (BMD). Tenofovir-diphosphate (TFV-DP) in red blood cells was used to categorize participants into high and low drug exposure groups. RESULTS: There were 101 participants, median age 20 years (range 15 to 22). Compared with low drug exposure, high-exposure participants showed increase from baseline in PTH and decline in FGF23 by study week 4, with no differences in creatinine, phosphate, or TRP. At 48 weeks, the median (interquartile range) percent decline in total hip BMD was greater in those with high- compared to low- exposure (-1.59 [2.77] vs +1.54 [3.34] %, respectively; P = .001); in high-exposure participants, this correlated with week 4 TFV-DP (inversely; r = -0.60, P = .002) and FGF23 (directly; r = 0.42; P = .039) but not other variables. CONCLUSIONS: These findings support the short-term renal safety of TDF/FTC PrEP in HIV-seronegative young men and suggest that endocrine disruption (PTH-FGF23) is a primary contributor to TDF-associated BMD decline in this age group. CLINICAL TRIALS REGISTRATION: NCT01769469.

DEAD-box helicase proteins accelerate folding and rearrangements of highly structured RNAs and RNA-protein complexes (RNPs) in many essential cellular processes. Although DEAD-box proteins have been shown to use ATP to unwind short RNA helices, it is not known how they disrupt RNA tertiary structure. Here, we use single molecule fluorescence to show that the DEAD-box protein CYT-19 disrupts tertiary structure in a group I intron using a helix capture mechanism. CYT-19 binds to a helix within the structured RNA only after the helix spontaneously loses its tertiary contacts, and then CYT-19 uses ATP to unwind the helix, liberating the product strands. Ded1, a multifunctional yeast DEAD-box protein, gives analogous results with small but reproducible differences that may reflect its in vivo roles. The requirement for spontaneous dynamics likely targets DEAD-box proteins toward less stable RNA structures, which are likely to experience greater dynamic fluctuations, and provides a satisfying explanation for previous correlations between RNA stability and CYT-19 unfolding efficiency. Biologically, the ability to sense RNA stability probably biases DEAD-box proteins to act preferentially on less stable misfolded structures and thereby to promote native folding while minimizing spurious interactions with stable, natively folded RNAs. In addition, this straightforward mechanism for RNA remodeling does not require any specific structural environment of the helicase core and is likely to be relevant for DEAD-box proteins that promote RNA rearrangements of RNP complexes including the spliceosome and ribosome.

TS of immunosuppression is a rare, disfiguring dermatologic condition caused by TS-associated polyomavirus in immunosuppressed patients. It is difficult to treat, with no clearly described approach to resolve the condition completely and safely. We report a child with a renal transplant who developed TS and was treated with significant reduction in immunosuppression and transient use of cidofovir cream. The combined approach, primarily with significant long-term reduction in immunosuppression guided by monitoring BK viremia in our patient, led to complete resolution of TS without recurrence or graft rejection by 5 years after transplant. This outcome was superior to all other reports of TS in children after transplantation. Closely monitoring for BK viremia, as a surrogate marker of over-immunosuppression, can guide adjustment in immunosuppressant medication to treat polyomavirus disease without developing the complication of graft rejection in a patient at significant risk.

OBJECTIVE: For chronically critically ill elderly patients on mechanical ventilation, prognosis for significant recovery may be minimal. These individuals, or their surrogates, may decide for "palliative extubation." A common prognostic question arises: "How long does she/he have?" This study describes demographics, mortality, time to death, and factors associated with death after palliative extubation. DESIGN, SETTING, AND PATIENTS: Retrospective 3-year study in community hospital with ethnically diverse elderly population. Chronically critically ill patients followed from palliative extubation to death or survival to discharge. MEASURES: Mortality/survival following palliative extubation, time to death or discharge, factors associated with death. RESULTS: Hundred and forty-eight subjects underwent palliative extubation. Mean age: 78 years, 60% female, ethnically diverse with 46% white, and 54% others. Top diagnostic categories: sepsis (47%) and respiratory failure (22%). After extubation, 114 patients (77%) died in hospital and 34 (23%) were discharged. Of those who died, median time to death 8.9 hours (range, 4 min to 7 d). Mortality proportion was 56% at 24 hours and increased with time. Factors associated with early death: Systolic blood pressure less than 90 (p = 0.002) and Charlson Comorbidity Index that is above 6 or 0 (p = 0.002). CONCLUSIONS: Palliative extubation at end of life was an option selected by an ethnically diverse elderly population. Approximately three-fourths of subjects died in hospital, and one-fourth was discharged alive. Over 50% who died did so within 24 hours, making this useful information for counseling and anticipatory planning. Subjects with systolic blood pressure less than 90 and Charlson Comorbidity Index that is very low or very high had higher mortality.

OBJECTIVES: Fetuses continue to be exposed to renin angiotensin system (RAS) blockers despite their known teratogenicity and a black box warning. We hypothesized that fetopathy from in utero exposure to RAS blockers has a broader spectrum of clinical manifestations than described previously and that there are a variety of clinical scenarios leading to such exposures. STUDY DESIGN: This was a retrospective study performed through the Midwest Pediatric Nephrology Consortium. Cases of RAS blocker fetopathy were identified, with determination of renal and extrarenal manifestations, timing of exposure, and the explanation for the fetal exposure. RESULTS: Twenty-four cases were identified. RAS blocker exposure after the first trimester was associated with more severe renal manifestations. Chronic dialysis or kidney transplantation was required in 8 of 17 (47%) patients with RAS blocker exposure after the first trimester and 0 of 7 patients with exposure restricted to the first trimester (P = .05). Extrarenal manifestations, some not previously noted in the literature, included central nervous system anomalies (cystic encephalomalacia, cortical blindness, sensorineural hearing loss, arachnoid cysts) and pulmonary complications (pneumothorax, pneumomediastinum). RAS blocker exposure usually was secondary to absent or poor prenatal care or undiagnosed pregnancy. CONCLUSION: RAS blocker fetopathy continues to be a cause of considerable morbidity, with more severe renal manifestations associated with exposure after the first trimester. A variety of significant extrarenal manifestations occur in these patients. Clinicians should emphasize the risk of fetopathy when prescribing RAS blockers to women of childbearing age.

BACKGROUND: Postoperative delirium in the elderly is a growing concern. Data regarding significant differences in postoperative cognitive dysfunction (POCD) in elderly persons undergoing laparoscopic versus open colon resection are not well established. OBJECTIVES: The goal of this study was to compare the incidence of POCD in laparoscopic versus open colon surgery in an elderly population. DESIGN AND SETTING: A prospective nonrandomized pilot study was conducted at an urban tertiary care hospital. PARTICIPANTS: The study included patients aged 65 years and above, without documented dementia who underwent elective colon surgery. MEASUREMENTS: We collected demographic and clinical data, including age, sex, polypharmacy, and comorbidities. The subjects underwent pre- and postoperative Cambridge Neuropsychological Test Automated Battery (CANTAB) testing. Worsening individual scores from the Paired Associated Learning (PAL) and Spatial Working Memory (SWM) portions of CANTAB determined the presence of POCD. Inflammatory cytokine (i.e., IL-6) levels were measured pre- and postoperatively. RESULTS: We enrolled 44 subjects (26 laparoscopic and 18 open surgery). The two groups did not differ significantly in age, sex, polypharmacy, and comorbidities. The average incidence of POCD was 47%. PAL scores worsened in 12/23 (52%) in the laparoscopic group and in 7/15 (47%) in the open group. These group differences lacked statistical significance (p = 0.75). SWM scores worsened in 14/25 (56%) in the laparoscopic group and in 6/18 (33%) in the open group, which was also not statistically significant (p = 0.12). No age difference occurred between the 'worsened scores' group and 'stable scores' group, and older age was not associated with POCD. IL-6 levels were higher in the open versus the laparoscopic group (p < 0.0001). CONCLUSION: In this pilot study, the average incidence of POCD was not statistically different between elderly subjects undergoing open versus laparoscopic surgery. Age did not influence the occurrence of POCD. Although inflammatory markers were significantly higher in the open group, consistent with a higher degree of stress response, this group did not have higher rates of delirium. This association is worth to be investigated in a larger sample.

BACKGROUND AND OBJECTIVES: Chronic kidney disease is a persistent chronic health condition commonly seen in pediatric nephrology programs. Our study aims to evaluate the sensitivity of the Patient Reported Outcomes Measurement Information System (PROMIS) pediatric instrument to indicators of disease severity and activity in pediatric chronic kidney disease. METHODS: This cross sectional study included 233 children 8-17 years old, with chronic kidney disease from 16 participating institutions in North America. Disease activity indicators, including hospitalization in the previous 6 months, edema, and number of medications consumed daily, as well as disease severity indicators of kidney function and coexisting medical conditions were captured. PROMIS domains, including depression, anxiety, social-peer relationships, pain interference, fatigue, mobility, and upper extremity function, were administered via web-based questionnaires. Absolute effect sizes (AES) were generated to demonstrate the impact of disease on domain scores. Four children were excluded because of missing glomerular filtration rate (GFR) estimations. RESULTS: Of the 229 children included in the final analysis, 221 completed the entire PROMIS questionnaire. Unadjusted PROMIS domains were responsive to chronic kidney disease activity indicators and number of coexisting conditions. PROMIS domain scores were worse in the presence of recent hospitalizations (depression AES 0.33, anxiety AES 0.42, pain interference AES 0.46, fatigue AES 0.50, mobility AES 0.49), edema (depression AES 0.50, anxiety AES 0.60, pain interference AES 0.77, mobility AES 0.54) and coexisting medical conditions (social peer-relationships AES 0.66, fatigue AES 0.83, mobility AES 0.60, upper extremity function AES 0.48). CONCLUSIONS: The PROMIS pediatric domains of depression, anxiety, social-peer relationships, pain interference, and mobility were sensitive to the clinical status of children with chronic kidney disease in this multi-center cross sectional study. We demonstrated that a number of important clinical characteristics including recent history of hospitalization and edema, affected patient perceptions of depression, anxiety, pain interference, fatigue and mobility. The PROMIS instruments provide a potentially valuable tool to study the impact of chronic kidney disease. Additional studies will be required to assess responsiveness in PROMIS score with changes in disease status over time.

BACKGROUND: The literature describing the attitude of Asians toward palliative care in the intensive care unit (ICU) is scarce. AIM: The purpose of this study was to compare outcomes of Asians and people of other ethnicities after palliative care intervention in the ICU. METHODS: A retrospective chart review was conducted of all ICU patients evaluated by palliative care; the outcomes measured were incidence of life-sustaining treatments, institution of advance care directives, and preferences for end-of-life care. RESULTS: The palliative care team evaluated 119 patients (46.2 percent Caucasian, 27.2 percent Asian, and 26.1 percent other ethnicities). There were no differences in demographics or clinical variables. Thirty-six percent of the Asians, 49 percent of the Caucasians, and 28.6 percent of the patients of other ethnicities (p = 0.19) had healthcare proxies. The palliative care team increased advance care directives by more than 40 percent in all groups (p < 0.001). There were no differences in the use of life-sustaining treatments or preferences for comfort measures among ethnic groups. CONCLUSION: Asians are as likely as people of other ethnicities to decide on advance care directives, life-sustaining treatments, and comfort measures after palliative care evaluation in the ICU.

The United States population not only is aging, but also becoming more ethnically diverse. Approximately half of elders who take medications find adherence challenging, and cultural diversity is one of the variables that may affect adherence. By better understanding patients' cultural perspectives, senior care pharmacists can more effectively address their medication management needs; failure to recognize these differences may contribute to misunderstanding or miscommunication that may affect treatment. When a patient does not adhere to prescribed medications, explore reasons and feelings. Different ethnic groups have varying communication styles and also seek different degrees of family involvement in diagnosis and treatment. Some mistrust in Western health care, choose to use herbs and nonpharmacologic agents, and have different time orientation that may affect adherence. Senior pharmacists have an active role in screening, evaluation, and counseling elderly, ethnically diverse patients. Applying general trends of cultural values should not be mistaken for stereotyping.
