RESUMEN

BACKGROUND: In all 50 states, early intervention (EI) services to improve long-term child cognitive and academic outcomes are provided to infants and toddlers with suspected or diagnosed developmental delays. When mothers of EI-enrolled children experience depressive symptoms, uptake of EI services can be compromised. AIMS: The purpose of the article is to present a depressive symptom screening intervention for mothers consisting of toolkit development for EI staff and families, symptom screening for mothers and follow-up protocol. To formally evaluate the implementation of the intervention, our research team followed the consolidated framework for implementation research (CFIR). METHODS: Participants were 12 EI service coordinators across two offices. Focus groups and individual interviews were used to develop the toolkit and education module. Through the five CFIR domains, we evaluated the implemented intervention in order to allow other teams to learn from our experiences. RESULTS: Our team successfully partnered with SCs to develop the intended deliverables. Still, the SCs found it challenging to conduct the screenings and reported mixed success. CONCLUSIONS: Preparation of EI SCs to integrate mental health screenings into their existing skillsets requires a high level of support from the research team, resulting in a rich understanding of the barriers-and potential rewards-for staff and families.

RESUMEN

Abaloparatide increased ultradistal radius bone mineral density (BMD) in the Abaloparatide Comparator Trial in Vertebral Endpoints (ACTIVE) trial. Over the subsequent 24 months in ACTIVExtend, ultradistal radius BMD gains were maintained with alendronate. Conversely, 1/3 radius BMD remained stable during ALN treatment in ACTIVExtend after decreasing during ACTIVE. INTRODUCTION: Abaloparatide (ABL) increased femoral neck, total hip, and lumbar spine bone mineral density (BMD) in postmenopausal women with osteoporosis and decreased the risk of vertebral and nonvertebral fractures in ACTIVE. Effects on fracture risk and BMD were maintained subsequently with alendronate (ALN) in ACTIVExtend. In a prespecified subanalysis of ACTIVE, ABL also increased BMD at the ultradistal radius. Our objective was to determine the efficacy of ABL followed by ALN vs placebo (PBO) followed by ALN on forearm BMD and fracture risk over 43 months in ACTIVExtend. METHODS: Ultradistal and 1/3 radius BMD (ACTIVE baseline to month 43) were measured (ABL/ALN, n = 213; PBO/ALN, n = 233). Wrist fracture rates were estimated for the ACTIVExtend intent-to-treat population (ABL/ALN, n = 558; PBO/ALN, n = 581) by Kaplan-Meier (KM) method. RESULTS: At cumulative month 25, mean increase from ACTIVE baseline in ultradistal radius BMD was 1.1% (standard error, 0.49%) with ABL/ALN vs - 0.8% (0.43%) with PBO/ALN (P < 0.01). BMD increases with ABL were maintained with ALN through month 43 in ACTIVExtend. BMD decreases at the 1/3 radius in ACTIVE (similar with ABL and PBO) were maintained through 24 months of ALN treatment in ACTIVExtend. Wrist fractures over 43 months occurred in 15 women with ABL/ALN (KM estimate, 2.8%) and 20 with PBO/ALN (KM estimate, 3.6%) (HR = 0.77, 95% CI 0.39, 1.50; P = not significant). CONCLUSION: Ultradistal radius BMD gains following treatment with ABL in ACTIVE were maintained over 24 months of ALN treatment in ACTIVExtend. Conversely, 1/3 radius BMD remained stable during ALN treatment in ACTIVExtend after decreasing during ACTIVE. TRIAL REGISTRATION: ClinicalTrials.gov : NCT01657162 submitted July 31, 2012.

RESUMEN

Disproportionate rates of suspension and expulsion, evident from early childhood, for students of color relative to White peers are a significant racial equity issue in the U.S. education system, with far-reaching effects. In this article, we present a logic model for educator-level interventions that have the potential to reduce disparate discipline practices and ultimately work toward a more equitable school climate. We describe how an integrated approach to supporting all children's constitutional right to a free public education, which is prevented by exclusionary discipline practices, must purposefully integrate social and emotional learning, classroom management, cultural competence, and racial equity approaches that target educators. Together, the integration of these approaches has the potential to impact initial, intermediate, and long-term education outcomes by enhancing educators' practices and raising awareness of their internal and interpersonal biases and role in perpetuating institutional racism in education. We conclude with recommendations for how this logic model can be used to guide future research to further our knowledge in this area to support educators in their practice and inform educational policy.

RESUMEN

OBJECTIVE: We aimed to assess inter-observer agreement in bone involvement evaluation and define accuracy and reproducibility of MDCT images analysis in Multiple Myeloma (MM), by comparing two acquisition protocols at two different institutions. METHODS: A total of 100 MM patients underwent whole body low-dose computed tomography (WB-LDCT), with two protocols: Group I (50 patients), 80 kV and 200-230 mAs; Group II, 120 kV-40 mAs. Four readers (two experts) retrospectively reviewed 22 anatomical districts, reporting the following for each patient: 1) osteolytic lesions; 2) cortical bone integrity; 3) fractures; 4) risk of vertebral collapse; 5) hyperattenuating bone lesions; and 6) extraosseous extension. Inter-observer agreement (by all readers, expert and young observers and comparison of the two protocols) was then statistically analyzed. RESULTS: According to Cohen's criteria, inter-observer agreement among the four readers and between experts and residents was good for the detection of bone lesions and extra-medullary extension, and for the evaluation of risk of collapse and cortical integrity. There was good agreement when comparing the two protocols. A greater variability was found for the evaluation of hyperattenuating lesions and the presence of fractures. CONCLUSIONS: WB-LDCT represents a reproducible and reliable technique that is helpful for defining bone disease in MM patients, with partial influence of readers' experience. KEY POINTS: • MDCT represents a reproducible technique for defining bone disease in MM. • Overall inter-observer agreement is good, even when comparing two different protocols. • Influence of readers' experience on image analysis is partial.

RESUMEN

OBJECTIVE: Provide the latest national and state estimates and correlates of the proportion of young children who are healthy and ready to learn (HRTL) using a revised measure from the National Survey of Children's Health (NSCH). METHODS: Data were analyzed for 11,121 children ages 3 to 5 years from the 2022 NSCH, an address-based, parent-completed survey on the health and well-being of children in the United States. A total of 27 items across 5 domains (early learning skills, social emotional development, self-regulation, motor development, and health) were used to calculate domain-specific assessments scored as "on track," "emerging," or "needs support" according to age-appropriate developmental expectations. Children "on track" in 4 to 5 domains with no domain that "needs support" were considered HRTL. RESULTS: In 2022, 63.6% of 3- to 5-year-old children were HRTL. The proportion of children "on track" ranged from just over two thirds for early learning skills and motor development to 88.9% for health. One million children, or 9.0%, needed support in multiple domains. Being HRTL was associated with child, family, community factors including participation in early childhood education, special health care needs status/type, male sex, reading/singing/storytelling by family members, adverse childhood experiences, parental mental health and education, food insufficiency, outdoor play, household language, neighborhood amenities, rural residence, medical home access. CONCLUSIONS: Nearly two thirds of young children are reported to be HRTL, meeting the Title V National Outcome Measure for School Readiness. Using a revised measure, modifiable factors are identified which offer a range of intervention opportunities at the child, family, and community levels.

RESUMEN

We examined the effects of insurance type on health service utilization among children with autism spectrum disorder (ASD) following autism insurance reform by analyzing the most recent data from the 2019 National Survey of Children's Health. Families with private insurance were less likely to report that their health insurance covered needed services compared to families with public insurance. Privately versus publicly insured children were not significantly different in receiving behavioral or medication treatment, or in parental frustration in efforts to obtain services. However, parents' frustration escalated with increased ASD severity. Findings from this study suggest the need for continuing to improve implementation of health insurance reform legislation and providing adequate ASD-related services for children with private insurance.

RESUMEN

This study investigated the utility of including teacher-reported callous-unemotional (CU) behaviors in the assessment of disruptive behaviors in school-based research. Participants included 138 first- and second-grade children (68% male; 76% eligible for free or reduced-price lunch; 61% Black, 9% Latinx, 23% White, and 7% multiracial) who completed assessments during the baseline assessment of an intervention study. Results indicated that teachers could distinguish CU from traditional indicators of disruptive behavior, including attention deficit hyperactivity disorder (ADHD) behaviors and conduct problems (CP). When considered alone, there was mixed evidence for the utility of CU behaviors. Although higher levels of CU behaviors explained unique variation in teacher-reported social competence and global impairment, CU behaviors did not explain unique variation in disciplinary infractions, classroom behavior, or academic functioning after accounting for ADHD and CP behaviors. A different pattern of results was evident when CU was considered in conjunction with ADHD and CP behaviors. Latent profile analyses identified three subgroups of participants (i.e., a nondisruptive group, an ADHD group, and a comorbid group, who exhibited elevated levels of ADHD, CP, and CU). Compared to the nondisruptive group, the ADHD group exhibited higher rates of off-task classroom behavior and worse academic functioning. The comorbid group exhibited moderate-to-large differences from both groups on teacher-reported and objective outcomes. The implications of these results are discussed with respect to the potential value of incorporating CU behaviors, which are becoming prominent in clinical psychology and psychiatry, into school-based research and for school psychology practice.

RESUMEN

This study examined parent characteristics and barriers to participation in a community-based preventive intervention with a sample of 201 parents from low-income and predominantly ethnic minority backgrounds. Person-centered analyses revealed five subgroups of parents who demonstrated variability in their parent characteristics, which included psychological resources and level of parental involvement in education. Group membership was associated with differences in school involvement and use of the psychoeducational intervention at home, after accounting for the number of barriers to engagement. For the intervention attendance variable, greater number of barriers was associated with decreased attendance only for parents in the resilient subgroup and the psychologically distressed subgroup. Attendance remained constant across levels of barriers for the other three subgroups of parents. The results of the study inform theory and practice regarding how to tailor preventive interventions to accommodate subgroups of parents within populations that experience barriers to accessing mental health services.

RESUMEN

OBJECTIVE: A randomised, double-blind study to compare the gastrointestinal (GI) tolerability, safety and efficacy of etoricoxib and diclofenac in patients with rheumatoid arthritis (RA). PATIENTS AND METHODS: A total of 4086 patients (mean age 60.8 years) diagnosed with RA were enrolled and received etoricoxib 90 mg daily (n = 2032) or diclofenac 75 mg twice daily (n = 2054). Use of gastroprotective agents and low-dose aspirin was allowed. The prespecified primary end point consisted of the cumulative rate of patient discontinuations due to clinical and laboratory GI adverse experiences (AEs). General safety was also assessed, including adjudicated thrombotic cardiovascular event data. Efficacy was evaluated using the Patient Global Assessment of Disease Status (PGADS; 0-4 point scale). RESULTS: Mean (SD; maximum) duration of treatment was 19.3 (10.3; 32.9) and 19.1 (10.4; 33.1) months in the etoricoxib and diclofenac groups, respectively. The cumulative discontinuation rate due to GI AEs was significantly lower with etoricoxib than diclofenac (5.2 vs 8.5 events per 100 patient-years, respectively; hazard ratio 0.62 (95% CI: 0.47, 0.81; p

RESUMEN

OBJECTIVE: To evaluate the immunogenicity, safety, and efficacy of 50 mg/mL liquid etanercept. METHODS: In a multicenter, open-label study, adults with active rheumatoid arthritis (RA) received 50 mg/mL liquid etanercept subcutaneously once weekly for 24 weeks. Immunogenicity was assessed at baseline and weeks 24 and 28, safety at all study visits, and efficacy at baseline and weeks 12 and 24. RESULTS: Of 222 treated patients, 88% completed the study; 81% were women; 84% were white; mean age was 53 years; mean RA duration was 10 years. Antibodies to etanercept, all non-neutralizing, were detected in 12 of 214 patients; 7 of the 12 were borderline positive (antibody titers <1:50). The presence of non-neutralizing anti-etanercept antibodies did not appear to affect clinical safety or efficacy. Few patients reported serious adverse events (6.3%), serious infections (2.3%), or withdrew because of adverse events (4.5%). Most adverse events were mild or moderate. The most common event, injection site reaction, occurred in 29.3% patients. At week 24, 63% of patients achieved an ACR20 response, 36% an ACR50 response, and 14% an ACR70 response. Similar responses were apparent by week 12. Week 24 mean improvement in the Health Assessment Questionnaire disability index scores was 0.6 points; improvement in the Short Form-36 Physical Component Score was 10.0 points. CONCLUSION: The 50 mg/mL liquid etanercept formulation administered once weekly was well tolerated. The incidence of anti-etanercept antibodies, the nature and frequency of adverse events, and improvements in signs and symptoms of RA and patient physical function were similar to those in previous etanercept studies.

RESUMEN

INTRODUCTION: Pulmonary artery sarcoma (PAS) is a rare tumor, whose therapeutic approach is mainly based on surgery, either pneumonectomy or pulmonary endarterectomy (PEA). The prognosis reported in published series is very poor, with survival of 1.5 months without any kind of treatment. PATIENTS AND METHODS: From January 2010 to January 2016, 1027 patients were referred to our hospital for symptoms of acute or chronic pulmonary thromboembolic disease. Twelve patients having a confirmed diagnosis of PAS underwent PEA. Median age was 64.5 years. Most patients had a long history of symptoms, having a median time of 7.5 months from onset of symptoms to surgery. RESULTS: Following PEA and cardiopulmonary rehabilitation, 10 patients received conventional chemotherapy with doxorubicin and ifosfamide, starting at a median of 42 days from surgery. Four patients also received radiotherapy. Four patients have died due to disease progression, while 7 are still alive, with 5 being disease-free at 4-55+ months from diagnosis. CONCLUSIONS: In patients with PAS, a multimodal approach including PEA, CT, and RT is feasible but it should be evaluated individually, according to the tumor extension and the patient's clinical condition. Apart from improving quality of life mainly by reducing or delaying symptoms due to PH, it may improve life expectancy.

RESUMEN

Women are more likely than men to suffer from anxiety disorders and major depression. These disorders share hyperresponsiveness to stress as an etiological factor. Thus, sex differences in brain arousal systems and their regulation by chronic stress may account for the increased vulnerability to these disorders in women. Social isolation is a model of early life stress that results in neurobiological alterations leading to increased anxiety-like and depressive-like behaviors. Here we investigated the sex difference in the effects of post-weaning social isolation on acute stress sensitivity and behavior in rats. In both sexes, social isolation at weaning reduced basal levels of the neuroactive steroid allopregnanolone in the brain and of corticosterone in plasma. Moreover, acute stress increased plasma corticosterone levels in both group-housed and socially isolated male and female rats; however this effect was greater in male than female rats subjected to social isolation. Intriguingly, group-housed female rats showed no change in plasma and brain levels of allopregnanolone after acute foot-shock stress. The absence of stress-induced effects on allopregnanolone synthesis might be due to the physiologically higher levels of this hormone in females vs. males. Accordingly, increasing allopregnanolone levels in male rats blunted the response to foot-shock stress in these animals. Socially isolated male, but not female, rats also display depressive-like behavior and increased hippocampal brain-derived neurotrophic factor (BDNF). The ovarian steroids could "buffer" the effect of this adverse experience in females on these parameters. Finally, the dexamethasone (DEX) suppression test indicated that the chronic stress associated with social isolation impairs feedback inhibition in both sexes in which an increase in the abundance of glucocorticoid receptors (GRs) in the hippocampus was found. Altogether, these results demonstrate that social isolation affects neuroendocrine reactivity to stress, plasticity and emotionality in a sexually dimorphic manner.

RESUMEN

PURPOSE: To explore a more direct method for evaluating tumor burden (TB) in Hodgkin's disease (HD) and to verify its prognostic importance. PATIENTS AND METHODS: The volume of TB at diagnosis was directly and retrospectively measured in 121 HD patients through images of the lesions recorded by computed tomographic (CT) scan of the thorax, abdomen, and pelvis for all deep sites of involvement and many superficial ones, and by ultrasonography (US) for the remaining superficial lesions. RESULTS: The TB, which was obtained from the sum of the volumes of all the lesions measured on CT scans and US and normalized to body-surface area (relative TB [rTB]), showed a median value of 102.6 cm(3)/m(2) (range, 2.2 to 582.8). At multivariate analysis for prognostic value, rTB was the parameter that statistically correlated best with time to treatment failure (P = 2.2 x 10(-6)), followed by erythrocyte sedimentation rate (ESR) (P =.0003), and serum fibrinogen (P =.0112). The prognostic discrimination allowed by rTB alone proved to be clearly superior to that obtained with the score of the International Prognostic Factor Project. The rTB was found to be correlated with many clinical staging parameters (bulky disease, number of involved lymph node regions, serum lactate dehydrogenase, ESR, hemoglobin, Karnofsky index), but its predictability from these variables was low (R(2) =.668). CONCLUSION: Relative TB is emerging as a strong prognostic factor in HD, more powerful than and largely independent of those hitherto known and used. Further studies are needed to confirm these results and exploit their clinical value, particularly the relationship among rTB, drug doses, and response.

RESUMEN

In 243 of 945 patients having lung percutaneous needle biopsy, we retrospectively evaluated 10 independent variables that potentially influence the incidence of pneumothorax (PNX): age, sex, lesion size, number of needle passes, needle intrapulmonary route, distance of the lesion from the chest wall, FEV1, FVC, residual volume, and total lung capacity percent predicted. The subjects considered (mean age, 61 years; 192 men and 51 women) performed respiratory function tests within 1 year of the procedure. The sample was also subdivided into four functional groups: restricted patients, obstructed ones, obstructed with alveolar hyperinflation patients, and normal subjects. The variables significantly correlated to PNX were the length of the needle intraparenchymal route (p<0.05) and the distance of the lesion from chest wall greater than 0 cm (p<0.01). None of the functional parameters was determinant in predicting PNX occurrence. Bronchial obstruction was not significantly associated with a higher risk of PNX. Nevertheless, when alveolar hyperinflation was associated with bronchial obstruction, the risk increased significantly (odds ratio, 2.38).

RESUMEN

We hypothesized that an altered effect of lung inflation on airway caliber may in part explain the isolated volume response to bronchodilators, i.e., an increase of forced vital capacity (FVC) without change in 1-s forced expiratory volume (FEV(1)). Small-airway caliber was measured by high-resolution computed tomography at functional residual capacity and total lung capacity in five chronic obstructive pulmonary disease patients with an isolated increase of FVC (FVC responders) and five with an increase of both FVC and FEV(1) (FVC-FEV(1) responders) after inhalation of salbutamol. In FVC-FEV(1) responders, the airway diameter increased with the cube root of increase in lung volume but was unchanged or even decreased in four of five FVC responders. FVC responders had more severe emphysema, as inferred from lung function and imaging studies, than FVC-FEV(1) responders. We speculate that longitudinal traction or space competition (Verbeken EK, Cauberghs M, and Van de Woestijne KP, J Appl Physiol 81: 2468-2480, 1996) are possible underlying mechanisms. We conclude that the isolated volume response to bronchodilators is associated with severe emphysema and likely results from an altered effect of lung inflation on airway caliber.

RESUMEN

A multicenter, parallel-group, double-blind, randomized, outpatient study compared the efficacy and safety of etodolac versus naproxen in patients with osteoarthritis of the knee. After a washout period free of nonsteroidal anti-inflammatory drugs, 254 patients self-administered etodolac 400 mg (n = 86), naproxen 500 mg (n = 82), or placebo (n = 86) twice daily for 4 weeks. Compliance exceeded 90% in all three groups. Primary efficacy variables improved progressively from baseline in all three groups. The extent of improvement was greater in the etodolac and naproxen groups than in the placebo group (P < or = 0.003), except with respect to target joint tenderness (P = 0.028, etodolac vs placebo; P = 0.013, naproxen vs placebo). There were no statistical differences between active treatment groups (P > 0.1). At end point, twice as many patients responded in the etodolac (59%) and naproxen groups (51%) than in the placebo group (26%; P < or = 0.01). There were no significant between-group differences in the numbers of patients who had an adverse experience, a serious adverse experience, or an adverse experience leading to study discontinuation; there were also no significant between-group differences in the distribution of adverse experiences. There were no unexpected clinical or laboratory experiences. Etodolac 400 mg twice daily was as effective and safe as naproxen 500 mg twice daily and both were superior to placebo in the management of osteoarthritis of the knee.

RESUMEN

Mesalamine-induced lung toxicity has often been described. We report on a case of a patient who underwent mesalamine treatment, though in the absence of established criteria required for diagnosing Crohn's disease (CD) or ulcerative colitis (UC). He developed an adverse respiratory reaction to the drug, thus definitely proving its lung damaging capacity. The clinical presentation included eosinophilic pleural effusion, a feature never previously described in association with mesalamine intake.

RESUMEN

We investigated the accuracy of both lymphography and computed tomography (CT) in detecting lymph node metastases in 58 patients with primary epithelial ovarian cancer (group a) and subsequently submitted to surgery including pelvic and/or lumbo-aortic lymphadenectomy. CT accuracy was also investigated in 41 patients with clinically suspected relapse of ovarian cancer (group b). In the first group (a) overall results in the pelvis were, respectively, for lymphography and CT: 94.8 vs 89.6% accuracy, 85.7 vs 57.1% sensitivity, 97.7 vs 100% specificity, 97.7 vs 100% positive predictive value and 95.5 vs 88% negative predictive value. In the lumbo-aortic region, we had: 88.8 vs 86.1% accuracy, 71.4 vs 64.2% sensitivity, 100% specificity and positive predictive value for both techniques, and 84.6 vs 81.6% negative predictive value. In the second group (b) CT accuracy, sensitivity and specificity were 90.2, 80 and 100%, respectively. CT, thanks to its high specificity and positive predictive value, can represent the method of choice for the evaluation of pelvic and lumbo-aortic lymph node metastases in untreated and relapsing ovarian cancer. CT demonstration of lymph node metastases can affect not only lesion staging, but also chemotherapy; different indications for lymphadenectomy may also depend on CT.

RESUMEN

The authors present two cases of impending rupture of abdominal aortic aneurysms correctly diagnosed by means of some unusual CT findings. The clinical signs were not clear. On CT examination, despite the absence of haematomas, minor, but precise, changes allowed the correct diagnosis: loss of definite contours of the aneurysm, non-homogeneous peri-aortic and peri- and para-renal adipose tissue, thickening of the renal fascia and a thin fluid collection over the psoas muscles.

RESUMEN

A prosthesis for a cruciate ligament of the knee involves the problem of implanting a short and small spring for which the load-deformation response cannot be duplicated by any single man-made material. This work presents a model of the elastic behavior of a two material composite prosthesis made of high-strength fibers spirally wound around a soft elastic core. At each end of the core, the fibers are attached to a pulling device. Under a tension load, the fibers exert a pressure on the core which deforms radially, permitting the elongation of the prosthesis. This allows the achievement of large deformation while both the fibers and the core remain in the elastic domain. The high strength of the spring is provided by the high yield strength of the fibers. The results show the influence of the design variables on the deformation of the prosthesis.
