RESUMO

BACKGROUND: Children with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency require treatment with glucocorticoids, usually at supraphysiologic doses, to address cortisol insufficiency and reduce excess adrenal androgens. However, such treatment confers a predisposition to glucocorticoid-related complications. In 2-week phase 2 trials, patients with CAH who received crinecerfont, a new oral corticotropin-releasing factor type 1 receptor antagonist, had decreases in androstenedione levels. METHODS: In this phase 3, multinational, randomized trial, we assigned pediatric participants with CAH, in a 2:1 ratio, to receive crinecerfont or placebo for 28 weeks. A stable glucocorticoid dose was maintained for 4 weeks, and the dose was then adjusted to a target of 8.0 to 10.0 mg per square meter of body-surface area per day (hydrocortisone dose equivalents), provided that the androstenedione level was controlled (≤120% of the baseline level or within the reference range). The primary efficacy end point was the change in the androstenedione level from baseline to week 4. A key secondary end point was the percent change in the glucocorticoid dose from baseline to week 28 while androstenedione control was maintained. RESULTS: A total of 103 participants underwent randomization, of whom 69 were assigned to the crinecerfont group and 34 to the placebo group; 100 (97%) remained in the trial at 28 weeks. At baseline, the mean glucocorticoid dose was 16.4 mg per square meter per day, and the mean androstenedione level was 431 ng per deciliter (15.0 nmol per liter). At week 4, the androstenedione level was substantially reduced in the crinecerfont group (-197 ng per deciliter [-6.9 nmol per liter]) but increased in the placebo group (71 ng per deciliter [2.5 nmol per liter]) (least-squares mean difference, -268 ng per deciliter [-9.3 nmol per liter]; P<0.001); the observed mean androstenedione value, obtained before the morning glucocorticoid dose, was 208 ng per deciliter (7.3 nmol per liter) in the crinecerfont group, as compared with 545 ng per deciliter (19.0 nmol per liter) in the placebo group. At week 28, the mean glucocorticoid dose had decreased (while androstenedione control was maintained) by 18.0% with crinecerfont but increased by 5.6% with placebo (least-squares mean difference, -23.5 percentage points; P<0.001). Headache, pyrexia, and vomiting were the most common adverse events. CONCLUSIONS: In this phase 3 trial, crinecerfont was superior to placebo in reducing elevated androstenedione levels in pediatric participants with CAH and was also associated with a decrease in the glucocorticoid dose from supraphysiologic to physiologic levels while androstenedione control was maintained.

RESUMO

BACKGROUND AND AIM: In relation to the new umbrella terminology for steatotic liver disease (SLD), we aimed to elucidate the prevalence, distribution, and clinical characteristics of the SLD subgroups in the primary care setting. APPROACH AND RESULTS: We retrospectively collected data from 2535 individuals who underwent magnetic resonance elastography and MRI proton density fat fraction during health checkups in 5 primary care health promotion clinics. We evaluated the presence of cardiometabolic risk factors according to predefined criteria and divided all the participants according to the new SLD classification. The prevalence of SLD was 39.13% in the total cohort, and 95.77% of the SLD cases had metabolic dysfunction (one or more cardiometabolic risk factors). The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) was 29.51%, with those of metabolic dysfunction and alcohol associated steatotic liver disease (MetALD) and alcohol-associated liver disease (ALD) at 7.89% and 0.39%, respectively. According to the old criteria, the prevalence of NAFLD was 29.11%, and 95.80% of the NAFLD cases fulfilled the new criteria for MASLD. The distribution of SLD subtypes was highest for MASLD, at 75.40%, followed by MetALD at 20.06%, cryptogenic SLD at 3.33%, and ALD at 1.01%. The MetALD group had a significantly higher mean magnetic resonance elastography than the MASLD or ALD group. CONCLUSION: Almost all the patients with NAFLD met the new criteria for MASLD. The fibrosis burden of the MetALD group was higher than those of the MASLD and ALD groups.

RESUMO

BACKGROUND & AIMS: The cost-effectiveness to screen hepatic fibrosis in at-risk population as recommended by several professional societies has been limited. This study aimed to investigate the cost-effectiveness of this screening strategy in the expanded at-risk population recently proposed by several societies. METHODS: A combined model of the decision tree and Markov models was developed to compare expected costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER) between screening and no screening groups. The model included liver disease-related health states and cardiovascular disease (CVD) states as a base-case analysis. Screening strategy consisted of fibrosis-4 index (FIB-4) followed by vibration-controlled transient elastography (VCTE) and intensive lifestyle intervention (ILI) as a treatment for diagnosed patients. RESULTS: Cost-effectiveness analysis showed that screening the at-risk population entailed $298 incremental costs and an additional 0.0199 QALY per patient compared to no screening (ICER $14 949/QALY). Screening was cost-effective based on the implicit ICER threshold of $25 000/QALY in Korea. When the effects of ILI on CVD and extrahepatic malignancy were incorporated into the cost-effectiveness model, the ICER decreased by 0.85 times from the base-case analysis (ICER $12 749/QALY). In contrast, when only the effects of liver disease were considered in the model, excluding cardiovascular disease effects, ICER increased from the baseline case analysis to $16 305. Even when replacing with medical costs in Japan and U.S., it remained cost-effective with the estimate below the countries' ICER threshold. CONCLUSIONS: Our study provides compelling evidence supporting the cost-effectiveness of FIB-4-based screening the at-risk population for advanced hepatic fibrosis.

RESUMO

AIMS: We aimed to explore the extent to which individuals previously diagnosed with nonalcoholic fatty liver disease (NAFLD) meet the criteria fulfilled with the new nomenclature, metabolic dysfunction-associated steatotic liver disease (MASLD), within an Asian primary clinic cohort. Additionally, we assessed the reliability of the diagnostic performance of FIB-4 and NAFLD fibrosis score (NFS) for MASLD within the primary clinic cohort. METHODS: This retrospective cross-sectional study included participants who underwent magnetic resonance elastography and abdominal ultrasonography during their health checkups at nationwide health promotion centers (n = 6740). RESULTS: The prevalence rates of NAFLD and MASLD diagnosed based on ultrasonography results were 36.7% and 38.0%, respectively. Notably, 96.8% of patients in the NAFLD cohort fulfilled the new criteria for MASLD. A small proportion of patients with NAFLD (n = 80, 3.2%) did not meet the MASLD criteria. Additionally, 168 patients (6.6%) were newly added to the MASLD group. The areas under the receiver operating characteristic curves for diagnosing advanced hepatic fibrosis for FIB-4 (0.824 in NAFLD vs. 0.818 in MASLD, p = 0.891) and NFS (0.803 in NAFLD vs. 0.781 in MASLD, p = 0.618) were comparable between the MASLD and NAFLD groups. Furthermore, the sensitivity, specificity, positive predictive value, and negative predictive value of FIB-4 and NFS for advanced fibrosis in MASLD were also comparable to those in NAFLD. CONCLUSIONS: Most patients (96.8%) previously diagnosed with NAFLD fulfilled the new criteria for MASLD in an Asian primary clinic cohort. Diagnostic performance of FIB-4 in the MASLD cohort demonstrated satisfactory results.

RESUMO

BACKGROUND: The increasing incidence of encountering lung nodules necessitates an ongoing search for improved diagnostic procedures. Various bronchoscopic technologies have been introduced or are in development, but further studies are needed to define a method that fits best in clinical practice and health care systems. RESEARCH QUESTION: How do basic bronchoscopic tools including a combination of thin (outer diameter 4.2 mm) and ultrathin bronchoscopes (outer diameter 3.0 mm), radial endobronchial ultrasound (rEBUS) and fluoroscopy perform in peripheral pulmonary lesion diagnosis? STUDY DESIGN AND METHODS: This is a retrospective review of the performance of peripheral bronchoscopy using thin and ultrathin bronchoscopy with rEBUS and 2D fluoroscopy without a navigational system for evaluating peripheral lung lesions in a single academic medical center from 11/2015 to 1/2021. We used a strict definition for diagnostic yield and assessed the impact of different variables on diagnostic yield, specifically after employment of the ultrathin bronchoscope. Logistic regression models were employed to assess the independent associations of the most impactful variables. RESULTS: A total of 322 patients were included in this study. The median of the long axis diameter was 2.2 cm and the median distance of the center of the lesion from the visceral pleural surface was 1.9 cm. Overall diagnostic yield was 81.3% after employment of the ultrathin bronchoscope, with more detection of concentric rEBUS views (93% vs. 78%, p < 0.001). Sensitivity for detecting malignancy also increased from 60.5% to 74.7% (p = 0.033) after incorporating the ultrathin scope into practice, while bronchus sign and peripheral location of the lesion were not found to affect diagnostic yield. Concentric rEBUS view, solid appearance, upper/middle lobe location and larger size of the nodules were found to be independent predictors of successful achievement of diagnosis at bronchoscopy. INTERPRETATION: This study demonstrates a high diagnostic yield of biopsy of lung lesions achieved by utilization of thin and ultrathin bronchoscopes. Direct visualization of small peripheral airways with simultaneous rEBUS confirmation increased localization rate of small lesions in a conventional bronchoscopy setting without virtual navigational planning.

RESUMO

In non-inferiority (NI) trials with time-to-event data, different types and patterns of censoring may occur, but their impact on trial results is not entirely clear. We investigated the influence of informative and non-informative censoring by conducting extensive simulation studies under the assumption that the NI margin is defined as a maximum acceptable hazard ratio and scenarios typically observed in recent NI trials. We found that while non-informative censoring tends to only affect the power, informative censoring can impact the treatment effect estimates, type I error rate, and power. The magnitude of these effects depends on the between-group differences in the failure and informative censoring risks, as well as the correlation between censoring and failure times, among other factors. The adverse impact of informative censoring was generally decreased with larger NI margins.

RESUMO

INTRODUCTION: The rapid increase in e-cigarette use over the past decade has triggered an important public health question on the potential association between e-cigarette use and combustible cigarette smoking. Following AMSTAR 2 and PRISMA guidelines, this evidence synthesis sought to identify and characterize any associations between e-cigarette use among individuals not smoking cigarettes and initiation of cigarette smoking. METHODS: The protocol was registered on September 24, 2018 (PROSPERO 2018 CRD42018108540). Three databases were queried from January 01, 2007 to April 26, 2023. Search results were screened using the PICOS review method. RESULTS: Among 55 included studies (40 "good" and 15 "fair"; evidence grade: "high") that adjusted for gender, age, and race/ethnicity between groups, generally, there was a significant association between non-regular e-cigarette use and initiation of cigarette smoking, further supported by the meta-analytic results (AOR 3.71; 95% CI 2.86-4.81). However, smoking initiation was most often measured as ever/current cigarette smoking. Two studies (quality: 2 "good") evaluated progression to regular cigarette smoking among individuals with regular use of e-cigarettes, and generally found no significant associations. One study ("good") evaluated smoking initiation among individuals with regular use of e-cigarettes, finding an increasing probability of ever smoking cigarettes with increased e-cigarette use. Twelve studies (10 "good" and two "fair") examining progression to regular smoking among individuals with non-regular use of e-cigarettes reported inconsistent findings. CONCLUSIONS: Numerous methodological flaws in the body of literature limit the generalizability of these results to all individuals who are not smoking cigarettes with few studies measuring established/regular use/smoking of e-cigarettes and cigarettes. Further, studies did not control adequately for specific confounding variables representing common liabilities between e-cigarette use and cigarette smoking, nor did they account for sufficient follow-up durations. Collectively, these flaws limit the generalizability of findings to the question of an association between e-cigarette use and cigarette smoking initiation.

RESUMO

INTRODUCTION: Vascular malformations (VMs) typically appear at birth and grow commensurately with patients. They can vary broadly in vessel type and tissue involvement, and upper extremity (UE) VMs can pose unique functional and aesthetic challenges in children. Given the advent of operative and nonoperative technologies like sclerotherapy and medications, a contemporary review of the surgical management of UE VMs is warranted. METHODS: We performed a retrospective review of all patients who had surgical management of VMs from 2010 to 2021 at The Children's Hospital of Philadelphia. Demographics, lesion characteristics, treatment (including preceding nonsurgical therapies), complications, and final outcomes were recorded. Operative notes were reviewed for date of operation, depth of excision, type of closure, and current procedural terminology code. RESULTS: Sixty-seven patients with 88 procedures were studied. Average patient age was 5.8 years, with 64% White and 67% male. Venous (34%) and lymphatic (19%) malformations were most common, and anatomic locations were most frequently on the hand (33%) and forearm (25%). The average lesion diameter was 4.2 cm, although this varied by location (eg, 2.9 cm, hand; 11.1 cm, chest wall). Fifty-eight patients (87%) underwent surgical excision as their index procedure, and 9 had sclerotherapy before surgery. Thirty-nine patients (60%) had subcutaneous excisions, and the remainder required subfascial or intramuscular excisions. Nearly all excisions were closed primarily (97%). Of the 53 patients with documented follow-up, 32 patients (60%) had complete resolution of their lesion as of their final visit. Thirty of these 32 patients with no clinical evidence of residual VM had only 1 surgery for excision. CONCLUSION: Upper extremity VMs were composed of diverse conditions with varying vessel types, size, depth, and anatomic sites. Surgical excision of VMs of the UE was safe and effective. A majority of VMs were fully excised after 1 procedure and frequently closed primarily with relatively low complication rates. Future work should investigate decision-making and outcomes of all treatment options of VMs of the UE for optimal functionality and aesthetics.

RESUMO

We describe congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, which is the most common primary adrenal insufficiency in children and adolescents. In this comprehensive review of CAH, we describe presentations at different life stages depending on disease severity. CAH is characterized by androgen excess secondary to impaired steroidogenesis in the adrenal glands. Diagnosis of CAH is most common during infancy with elevated 17-hydroxyprogesterone levels on the newborn screen in the United States. However, CAH can also present in childhood, with late-onset symptoms such as premature adrenarche, growth acceleration, hirsutism, and irregular menses. The growing child with CAH is treated with hydrocortisone for glucocorticoid replacement, along with increased stress doses for acute illness, trauma, and procedures. Mineralocorticoid and salt replacement may also be necessary. Although 21-hydroxylase deficiency is the most common type of CAH, there are other rare types, such as 11ß-hydroxylase and 3ß-hydroxysteroid dehydrogenase deficiency. In addition, classic CAH is associated with long-term comorbidities, including cardiometabolic risk factors, impaired cognitive function, adrenal rest tumors, and bone health effects. Overall, early identification and treatment of CAH is important for the pediatric patient.

RESUMO

We describe a 15-year-old boy who presented with low back pain due to vertebral compression fractures, growth deceleration, excessive weight gain, rounded facies, dorsocervical fat pad, and hypertension. He was diagnosed as having Cushing syndrome (CS) due to primary pigmented nodular adrenocortical disease resulting in excess cortisol produced by the adrenal glands, leading to disruption of the hypothalamic-pituitary-adrenal axis. The most common cause of CS is exogenous glucocorticoids, with endogenous causes being extremely rare, often leading to delay in diagnosis or misdiagnosis. Herein, we review clinical presentation, screening for hypercortisolism, and decision-making in the diagnosis of CS, as well as therapeutic approaches. The wide range of clinical presentations in pediatric CS and the rarity of the condition can lead to difficulty in the recognition, diagnosis, and subsequent management of these patients. CS can be difficult to differentiate from more common exogenous obesity, and outpatient screening of cortisol excess is challenging. Early recognition and treatment of CS is necessary to avoid multisystemic complications, and patients with suspected endogenous CS should be referred to a tertiary care center with experienced pediatric endocrinology and surgery specialists. Further confirmatory diagnostic tests are necessary to distinguish corticotropin-independent from corticotropin-dependent forms of CS, including a high-dose dexamethasone suppression test, a corticotropin-releasing hormone stimulation test, and imaging. There can be challenges to the evaluation of CS, including complex inpatient testing and difficulty with localization on imaging. Long-term sequelae of CS, including adrenal insufficiency, obesity, hypertension, and mental health disorders, may remain despite definitive surgical treatment, meriting close follow-up with the primary care clinician and subspecialists.

RESUMO

BACKGROUND & AIMS: The purpose of this study was to investigate the proportion of subjects with metabolic dysfunction-associated fatty liver disease (MAFLD) and to assess the degree of hepatic fibrosis and cardiovascular risk in metabolically healthy MAFLD subjects. METHODS: A total of 6740 subjects who underwent both magnetic resonance elastography and abdominal ultrasound were included in this study. Significant (≥3.0 kPa) and advanced (≥3.6 kPa) hepatic fibrosis were evaluated by magnetic resonance elastography. The metabolic unhealthy status among subjects with MAFLD was defined as the presence of diabetes or 2 or more metabolic risk abnormalities. RESULTS: The prevalence of MAFLD among the health examination cohort was 44.5% (3002 of 6740). A total of 26.6% (800 of 3002) of MAFLD subjects were metabolically healthy (≤1 risk factors and no diabetes), and 56.3% of MAFLD subjects (1691 of 3002) did not have metabolic syndrome. Hepatic fibrosis burden and cardiovascular risk were significantly higher in the metabolic unhealthy MAFLD group than in the healthy control group. However, the prevalence of significant (5.8% vs 4.3%; P = .099) and advanced hepatic fibrosis (0.8% vs 0.7%; P = .934) did not differ between the metabolically healthy MAFLD and healthy control groups. The prevalence of carotid artery plaque in the metabolically healthy MAFLD (32.7% vs 30.7%; P = .453) group was not different from that in the healthy control group. CONCLUSIONS: Contrary to the definition of MAFLD, a non-negligible number of metabolically healthy individuals are included in the MAFLD group. The metabolic healthy MAFLD group showed a comparable fibrosis burden and prevalence of carotid artery plaque compared with the healthy control group.

RESUMO

BACKGROUND & AIMS: Most noninvasive tests (NITs) for hepatic fibrosis are designed for middle-aged patients with chronic liver disease. We compared the diagnostic performance of major NITs (aspartate aminotransferase-to-platelet ratio index [APRI], Fibrosis-4 index, and nonalcoholic fatty liver disease fibrosis score) for a community-based cohort. METHODS: This cross-sectional study analyzed 8775 participants who underwent magnetic resonance elastography at community health check-up centers. Advanced hepatic fibrosis (≥F3) was defined by magnetic resonance elastography thresholds of 3.6 kPa. The diagnostic performance of 3 NITs was evaluated according to the etiology of liver disease, sex, metabolic syndrome, obesity, and increased aminotransferase levels in 4 age groups. RESULTS: The APRI generally showed the best area under the receiver operating characteristic curve in patients aged 45 years or younger, and it was statistically significant in patients with chronic viral hepatitis and alcoholic fatty liver disease (P < .043). The best APRI cut-off value for detecting advanced hepatic fibrosis was 0.4, with a sensitivity and specificity of 75.8% and 73.5%, respectively, in the community-based cohort. The APRI showed balanced sensitivity and specificity across all age groups, whereas the other metrics showed low sensitivity in those aged <45 and low specificity in those >65 years. CONCLUSIONS: The APRI showed better sensitivity and negative predictive value than the Fibrosis-4 index and the nonalcoholic fatty liver disease fibrosis score in community-based populations with mixed etiology, and, thus, can be performed as the primary test in young adults (age, ≤45 y).

RESUMO

INTRODUCTION: Previous studies have shown that ultrasonography has high specificity (80%-100%) but low sensitivity (50%-70%) in diagnosing fatty liver; sensitivity is especially low for mild steatosis. In this study, we aimed to reappraise the diagnostic performance of B-mode ultrasonography (B-USG) for fatty liver disease. METHODS: We performed a retrospective, multinational, multicenter, cross-sectional, observational study (6 referral centers from 3 nations). We included 5,056 participants who underwent both B-USG and magnetic resonance proton density fat fraction (MRI-PDFF) within a 6-month period. The diagnostic performance of B-USG was compared with that of MRI-PDFF as a reference standard for fatty liver diagnosis, using sensitivity, specificity, positive and negative predictive values, diagnostic accuracy, and area under the receiver operating characteristic curve (AUC). RESULTS: B-USG showed a sensitivity of 83.4%, specificity of 81.0%, and AUC of 0.822 in diagnosing mild liver steatosis (6.5% ≤MRI-PDFF ≤14%). The sensitivity, specificity, and AUC in diagnosing the presence of fatty liver disease (MRI-PDFF ≥6.5%) were 83.4%, 81.0%, and 0.822, respectively. The mean PDFF of B-USG-diagnosed nonfatty liver differed significantly from that of diagnosed mild liver steatosis (3.5% ± 2.8% vs 8.5% ± 5.0%, P < 0.001). The interinstitutional variability of B-USG in diagnosing fatty liver was similar in diagnostic accuracy among the 6 centers (range, 82.8%-88.6%, P = 0.416). DISCUSSION: B-USG was an effective, objective method to detect mild liver steatosis using MRI-PDFF as comparison, regardless of the etiologies and comorbidities.

RESUMO

OBJECTIVE: Infants and toddlers with classical congenital adrenal hyperplasia (CAH) are at high risk for morbidity/mortality arising from life-threatening adrenal crisis. Management of acute illnesses in CAH requires an understanding of factors leading to emergency department (ED) visits and hospitalizations in the first few years of life. We, therefore, examined adrenal crisis at prehospital and ED stages of illness in young children with CAH as they related to medical outcomes. PATIENTS AND DESIGN: Retrospective cohort study of 39 children with CAH due to 21-hydroxylase deficiency (0-4 years of age) and 27 age-matched controls. MEASUREMENTS: ED visit, acute illness symptoms (fever, vomiting, diarrhoea) and other characteristics (hospitalizations, administration of stress-dose hydrocortisone, electrolyte abnormalities). RESULTS: CAH infants and toddlers had significantly higher rates of ED visits (0.50 [0.25-0.88] per person-year) than controls (0 [0-0] per person-year; p < .001). Moreover, CAH children under 6 months old had significantly higher rates of ED visits compared with older ages. Only 50% (51/102) of illness-related ED visits in CAH children were preceded by the administration of either oral (46/51) or intramuscular (11/51) stress dosing by parents. A total of 10.8% of ED visits resulted in hospital admission. Controlling for age and 17-hydroxyprogesterone at diagnosis, electrolyte abnormalities and administration of parenteral hydrocortisone in the ED significantly predicted hospital admission. Receiving a hydrocortisone injection before the ED was a significant predictor of having electrolyte abnormalities. CONCLUSIONS: Infants and toddlers with classical CAH are at high risk for acute illness and hospitalizations and often do not receive adequate stress dosing before the ED.

RESUMO

OBJECTIVES: We investigated sarcopenia prevalence using various diagnostic criteria based on dual-energy X-ray absorptiometry (DXA) and computed tomography (CT) in gastric cancer patients who underwent gastrectomy, and evaluated the association between sarcopenia and perioperative complications. METHODS: This retrospective study included consecutive patients with gastric cancer who underwent gastrectomy, and preoperative DXA and CT from January 2013 to November 2020. Body composition was measured using DXA and CT. Height-adjusted DXA-based Appendicular Skeletal Muscle Mass Index (ASMI) and CT-based skeletal muscle cross-sectional area at the L3 level (SMI) were measured. Sarcopenia and sarcopenic obesity were defined using reported cutoff values. The chi-square test and univariate analysis were performed to determine risk factors for significant and severe perioperative complications (Clavien-Dindo Grades ≥ 2 and ≥ 3, respectively). RESULTS: In total, 77 males and 43 females aged 61.4 ± 11.0 years were included. ASMI and SMI were correlated (r = 0.819), but sarcopenia prevalence varied (20.0-63.3%), depending on the criteria applied. Univariate analysis revealed sarcopenia defined using the Asian Working Group on Sarcopenia (AWGS) criteria and sarcopenic obesity as risk factors for significant (odds ratio [OR] 2.76, p = 0.030 vs. OR 4.31, p = 0.002) and severe perioperative complications (OR 3.77, p = 0.036 vs. OR 4.78, p = 0.010). In subgroup analyses, sarcopenia and sarcopenic obesity were significantly associated with perioperative complications only in males. CONCLUSION: Perioperative complication risk can be predicted from sarcopenia defined using the AWGS criteria and sarcopenic obesity measured using DXA and CT, particularly in males. KEY POINTS: • The prevalence of sarcopenia varies due to definition differences. • Sarcopenia and sarcopenic obesity are risk factors for significant and severe perioperative complications, particularly in males. • Our results suggest that physicians need to pay attention to perioperative complications after surgical treatment of male patients with sarcopenia and sarcopenic obesity.

RESUMO

PURPOSE: We sought to improve caregiver retention of critical initial hospital discharge instructions using a multidisciplinary, team-based intervention for newly diagnosed pediatric cancer patients at high risk for unfavorable outcomes. MATERIALS AND METHODS: A multidisciplinary team of pediatric residents, nurses, social workers, pharmacists and hematology/oncology faculty implemented practices to optimize teaching of key discharge material as part of four Plan-Do-Study-Act intervention cycles. An 11-question survey distributed at the first post-discharge clinic visit assessed the efficacy of the intervention, as defined by caregiver retention of critical home instructions. RESULTS: Thirty-nine caregivers of pediatric cancer patients in an urban academic tertiary-care children's hospital took part in this project. Overall retention of key discharge information was greater in the post-intervention cohort compared to the baseline cohort (median total scores: 89 and 63, respectively; p = .001). Improvements in the proportions of correct responses post-intervention were also observed across all subject matters: from 0.57 to 0.88 for fever guidelines (p = .059), from 0.71 to 0.78 for signs of sepsis (p = .65), from 0.57 to 1.00 for accurate choice of on-call number (p = .004), and from 0.71 to 0.94 for antiemetic management (p = .14). CONCLUSION: Initiation of our comprehensive cancer-specific program to improve caregiver retention of discharge instructions at the first post-hospitalization clinic visit has been successful and sustainable. This project demonstrated that a multi-disciplinary collaborative team effort increases caregiver retention of critical health information, and this has potential to lead to improved outcomes for patients.

RESUMO

OBJECTIVE: Advanced practice providers (APPs) are a critical component of health care teams, especially in the neonatal intensive care unit. At times, APPs and neonatal-perinatal medicine (NPM) fellows may experience tension in their professional relationship. They may perceive the other's performance and abilities differently. We hypothesized that satisfaction with the APP-NPM fellow interprofessional relationship would be associated with higher perception of APP competence by NPM fellows. STUDY DESIGN: We surveyed 274 medical providers: NPM fellows (24.8%), NPM program directors (24.5%), and APPs (50.7%). APPs were defined as neonatal nurse practitioners, pediatric nurse practitioners, physician assistants, or neonatal hospitalists. We obtained demographic data, information about sources of conflict in the APP-NPM fellow relationship, level of satisfaction with the relationship, and targeted interventions for improvement. NPM fellow perception of APP competence as well as APP self-assessed competence were elicited. Statistical analyses were performed with chi-square tests and Fisher's exact tests. RESULTS: Overall, APPs and NPM fellows were generally satisfied with their relationship. All groups reported APP competence as equivalent to a third-year NPM fellow. NPM fellow perception of APP competence increased with year of fellow training. Higher perceived APP competence by NPM fellows correlated with higher relationship satisfaction scores. Difficulties with teamwork, communication and respect were associated with lower satisfaction within the APP-NPM fellow relationship. CONCLUSION: The professional working dynamic between these two groups is viewed positively by all. Satisfaction with the APP-NPM fellow relationship correlated with higher perception of APP competence by NPM fellows. Targeted interventions that increase NPM fellow perception of APP competence and ameliorate the difficulties encountered in the APP-NPM fellow relationship may improve this interprofessional relationship. KEY POINTS: · Advanced practice providers and NPM fellows may have similar responsibilities leading to challenges.. · NPM fellows with higher perceived competence of APPs had higher satisfaction with their relationship.. · Training APPs to teach, creating interprofessional education, and routine debrief sessions may help..

RESUMO

BACKGROUND & AIMS: There are several reports on the prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD). However, the prevalence of advanced hepatic fibrosis in MAFLD is largely unknown. We aimed to evaluate the prevalence of advanced fibrosis in MAFLD. METHODS: A total of 6775 subjects from nationwide 13 health check-up centres were included in this cross-sectional study. Fatty liver was evaluated using ultrasonography. Significant (≥F2) and advanced (≥F3) hepatic fibrosis were defined by MRE thresholds of 3.0 kPa (range: 2.99-3.65 kPa) and 3.6 kPa (range: 3.4-3.9 kPa) respectively. The sex- and age-standardized prevalence of MAFLD and hepatic fibrosis was estimated. RESULTS: The sex- and age-standardized prevalence of MAFLD was 33.9%. The prevalence of obesity (BMI ≥25 kg/m2 ) in MAFLD was 71.1%, and 79.0% of obese subjects had MAFLD. The prevalence of diabetes in MAFLD was 13.3%, and 73.6% of subjects with diabetes had MAFLD. The sex- and age-standardized prevalence of significant (≥F2) and advanced hepatic fibrosis (≥F3) amongst MAFLD was 9.7% (range: 3.0-9.8%) and 3.0% (range: 2.6-4.6%) respectively. The prevalence of advanced hepatic fibrosis in overweight/obese (group I), lean (group II) and diabetic (group III) MAFLD was 2.3%, 3.1% and 9.5% respectively. CONCLUSION: The sex- and age-standardized prevalence of advanced fibrosis was 3.0% (range: 2.6-4.6%) in subjects with MAFLD.

RESUMO

INTRODUCTION: Opioids are often used to manage postoperative pain. Non-narcotic alternatives have increasingly been used to reduce opioid usage. We conducted an open-label randomized non-inferiority clinical trial to compare non-opioid to opioid therapy for pain management after nephrolithiasis surgery. METHODS: Patients undergoing elective ureteroscopy or percutaneous nephrolithotomy between July 2018 and May 2021 were randomized to receive ketorolac (non-opioid) or oxycodone-acetaminophen (opioid). Each patient was surveyed one week postoperatively to assess pain outcomes. Patient demographics, surgical variables, number of pills used, constipation, and adverse events were also assessed. We evaluated whether non-opioid analgesia was non-inferior to opioid analgesia for postoperative pain, assuming a non-inferiority margin of 1.3 in pain score between groups. RESULTS: Analyses were based on 90 patients with postoperative pain data: 44 in the ketorolac group and 46 in the oxycodone-acetaminophen group. The groups were similar regarding demographics, type of surgery, ureteral stent placement, and stone burden. Non-inferiority of non-opioids compared to opioids was demonstrated for all outcomes. At follow-up, the average pain scores were 3.20 ± 1.94 (SD) in the non-opioid group and 4.17 ± 1.84 in the opioid group (difference = - 0.96; 95% CI: - 1.76, - 0.17, p = 0.018). The mean proportions of unused pills were similar between groups (p = 0.47) as were rates of constipation (p = 0.32). CONCLUSIONS: Non-opioid analgesia was non-inferior to opioid analgesia in pain management after kidney stone surgery. This trial contributes to the evidence that non-opioid analgesics should be considered an effective option for pain management following non-invasive urologic procedures.

RESUMO

AIMS: Fibrosis-4 index (FIB-4) and non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) are the two most widely used non-invasive tools for screening of advanced fibrosis in subjects with NAFLD. Since metabolic dysfunction-associated fatty liver disease (MAFLD) has been proposed as a new category of fatty liver disease, we aimed to compare the diagnostic performance of FIB-4 and NFS in subjects with MAFLD and in various subgroups. METHODS: This study was designed as cross-sectional study. Data from 6775 subjects who underwent magnetic resonance elastography (MRE) and abdominal ultrasonography at the same time during a health check-up at 13 various health check-up centers were retrospectively reviewed. Advanced fibrosis was defined as an MRE value of ≥3.6 kPa. RESULTS: The area under the receiver operating characteristic curves (AUROCs) of FIB-4 and NFS for diagnosing advanced fibrosis were similar in subjects with MAFLD. However, the AUROC of NFS was lower than that of FIB-4 in the diabetic subgroup of MAFLD (0.809 in FIB-4 vs. 0.717 in NFS, p = 0.002). The performances of both FIB-4 and NFS were poor in the subgroup of MAFLD with significant alcohol intake. CONCLUSIONS: The overall diagnostic performance of FIB-4 and NFS for diagnosing advanced fibrosis did not differ among subjects with MAFLD. However, the performance of NFS was lower in the diabetes subgroup of MAFLD. The diagnostic performance of FIB-4 was better for fibrosis in various subgroups of MAFLD.
