RESUMO

Erythropoiesis-stimulating agents (ESAs) are the first-line treatment option for anemia in patients with lower-risk myelodysplastic syndromes (LR-MDS). A systematic literature review was conducted to identify evidence of the association between prognostic factors and ESA response/failure in LR-MDS. MEDLINE, Embase, and relevant conferences were searched systematically for studies assessing the association between prognostic factors and ESA response/failure in adult patients. Of 1566 citations identified, 38 were included. Patient risk status in studies published from 2000 onwards was commonly assessed using the International Prognostic Scoring System (IPSS) or revised IPSS. ESA response was generally assessed using the International Working Group MDS criteria. Among the included studies, statistically significant relationships were found, in both univariate and multivariate analyses, between ESA response and the following prognostic factors: higher hemoglobin levels, lower serum erythropoietin levels, and transfusion independence. Furthermore, other prognostic factors such as age, bone marrow blasts, serum ferritin level, IPSS risk status, and karyotype status did not demonstrate statistically significant relationships with ESA response. This systematic literature review has confirmed prognostic factors of ESA response/failure. Guidance to correctly identify patients with these characteristics could be helpful for clinicians to provide optimal treatment.

RESUMO

BACKGROUND: In the first half of 2022, the increase in cases of severe acute hepatitis in children with no epidemiological link and unknown cause has aroused concern worldwide. In this study, we aimed to determine the frequency of adenovirus in children with hepatitis of unknown origin in Turkey. METHODS: In this study, which was conducted with the participation of 16 centers from Turkey, between July 2022 and January 2023, 36 pediatric patients under the age of 18 who met the definition of acute hepatitis were included. RESULTS: Twenty (55,6%) of patients were female and 16 (44,4%) were male, with a mean age of 41.55 ± 39.22 (3-192) months. The most common symptoms were fever (66.7%), weakness (66.7%), loss of appetite (66.7%), fatigue (61.1%), vomiting (61.1%), and diarrhea (47.2%). Six (16 %) children had acute hepatic failure. Eight of the 15 children (46%) had respiratory viral infections (rhinovirus/enterovirus, n = 4; rhinovirus + parainfluenza, n = 1; parainfluenza, n = 1, SARS-CoV-2 n = 2). Adenovirus was detected in 16 (44%) patients. Adenovirus and coinfections were detected in 7 patients. History of diarrhea and fatigue in the last month was significantly higher in the adenovirus group ( P = 0.023 and 0.018). One child who had both adenovirus and rhinovirus infection required liver transplantation; all others recovered with supportive care. CONCLUSION: There were no deaths in our series; however, the number of cases, etiology, and severity of the clinical course may have differed between countries owing to differences in case definitions, laboratory facilities, or regional genetic differences.

RESUMO

BACKGROUND: Patients with transfusion-dependent (TD) ß-thalassemia require long-term red blood cell transfusions (RBCTs) that lead to iron overload, impacting health-related quality of life (HRQoL). METHODS: The impact of luspatercept, a first-in-class erythroid maturation agent, versus placebo on HRQoL of patients with TD ß-thalassemia was evaluated in the phase 3 BELIEVE trial. HRQoL was assessed at baseline and every 12 weeks using the 36-item Short Form Health Survey (SF-36) and Transfusion-dependent Quality of Life questionnaire (TranQol). Mean change in HRQoL was evaluated from baseline to week 48 for patients receiving luspatercept + best supportive care (BSC) and placebo + BSC and between luspatercept responders and non-responders. RESULTS: Through week 48, for both groups, mean scores on SF-36 and TranQol domains were stable over time and did not have a clinically meaningful change. At week 48, more patients who achieved clinical response (≥50% reduction in RBCT burden over 24 weeks) in the luspatercept + BSC group had improvement in SF-36 Physical Function compared with placebo + BSC (27.1% vs. 11.5%; p = .019). CONCLUSIONS: Luspatercept + BSC reduced transfusion burden while maintaining patients' HRQoL. HRQoL domain improvements from baseline through 48 weeks were also enhanced for luspatercept responders.

RESUMO

OBJECTIVES: The non-transfusion-dependent beta-thalassaemia-patient-reported outcome (NTDT-PRO) questionnaire was developed for assessing anaemia-related tiredness/weakness (T/W) and shortness of breath (SoB) among patients with NTDT. Psychometric properties were evaluated using blinded data from the BEYOND trial (NCT03342404). DESIGN: Analysis of a phase 2, double-blind, randomised, placebo-controlled trial. SETTING: USA, Greece, Italy, Lebanon, Thailand and the UK. PARTICIPANTS: Adults (≥18 years) (N=145) with NTDT who had not received a red blood cell transfusion within 8 weeks prior to randomisation, with mean baseline haemoglobin level ≤100 g/L. MEASURES: NTDT-PRO daily scores from baseline until week 24, and scores at select time points for the 36-Item Short Form Health Survey version 2 (SF-36v2), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and Patient Global Impression of Severity (PGI-S). RESULTS: Cronbach's alpha at weeks 13-24 was 0.95 and 0.84 for the T/W and SoB domains, respectively, indicating acceptable internal consistency reliability. Among participants self-reporting no change in thalassaemia symptoms via the PGI-S between baseline and week 1, intraclass correlation coefficients were 0.94 and 0.92 for the T/W and SoB domains, respectively, indicating excellent test-retest reliability. In a known-groups validity analysis, least-squares mean T/W and SoB scores at weeks 13-24 were worse in participants with worse scores for the FACIT-F Fatigue Subscale (FS), SF-36v2 vitality or PGI-S. Indicating responsiveness, changes in T/W and SoB domain scores were moderately correlated with changes in haemoglobin levels, and strongly correlated with changes in SF-36v2 vitality, FACIT-F FS, select FACIT-F items and the PGI-S. Improvements in least-squares mean T/W and SoB scores were higher in participants with greater improvements in scores on other PROs measuring similar constructs. CONCLUSIONS: The NTDT-PRO demonstrated adequate psychometric properties to assess anaemia-related symptoms in adults with NTDT and can be used to evaluate treatment efficacy in clinical trials.

RESUMO

Red blood cell transfusion independence (RBC-TI) is an important goal in treating lower-risk myelodysplastic syndromes with ring sideroblasts. In the phase 3 MEDALIST study, RBC-TI of ≥ 8 weeks was achieved by significantly more luspatercept- versus placebo-treated patients in the first 24 weeks of treatment. In this post hoc analysis, we evaluated RBC transfusion units and visits based on patients' baseline transfusion burden level and the clinical benefit of luspatercept treatment beyond week 25 in initial luspatercept nonresponders (patients who did not achieve RBC-TI ≥ 8 weeks by week 25) but continued luspatercept up to 144 weeks. RBC transfusion burden, erythroid response, serum ferritin levels, and hemoglobin levels relative to baseline were evaluated. Through week 25, fewer RBC transfusion units and visits were observed in luspatercept-treated patients versus placebo, regardless of baseline transfusion burden. This continued through 144 weeks of luspatercept treatment, particularly in patients with low baseline transfusion burden. Sixty-eight patients were initial nonresponders at week 25 but continued treatment; most (81%) received the maximum dose of luspatercept (1.75 mg/kg). Sixteen percent achieved RBC-TI for ≥ 8 weeks during weeks 25-48, 26% had reduced RBC transfusion burden, 10% achieved an erythroid response, 44% had reduced serum ferritin, and hemoglobin levels increased an average of 1.3 g/dL from baseline. These data have implications for clinical practice, as transfusion units and visits are less in luspatercept-treated patients through week 25 regardless of baseline transfusion burden, and continuing luspatercept beyond week 25 can potentially provide additional clinical benefits for initial nonresponders. Trial registration: NCT02631070.

RESUMO

BACKGROUND: Radial head fractures are often evaluated in emergency departments and can easily be missed. Automated or semi-automated detection methods that help physicians may be valuable regarding the high miss rate. PURPOSE: To evaluate the accuracy of combined deep, transfer, and classical machine learning approaches on a small dataset for determination of radial head fractures. MATERIAL AND METHODS: A total of 48 patients with radial head fracture and 56 patients without fracture on elbow radiographs were retrospectively evaluated. The input images were obtained by cropping anteroposterior elbow radiographs around a center-point on the radial head. For fracture determination, an algorithm based on feature extraction using distinct prototypes of pretrained networks (VGG16, ResNet50, InceptionV3, MobileNetV2) representing four different approaches was developed. Reduction of feature space dimensions, feeding the most relevant features, and development of ensemble of classifiers were utilized. RESULTS: The algorithm with the best performance consisted of preprocessing the input, computation of global maximum and global mean outputs of four distinct pretrained networks, dimensionality reduction by applying univariate and ensemble feature selectors, and applying Support Vector Machines and Random Forest classifiers to the transformed and reduced dataset. A maximum accuracy of 90% with MobileNetV2 pretrained features was reached for fracture determination with a small sample size. CONCLUSION: Radial head fractures can be determined with a combined approach and limitations of the small sample size can be overcome by utilizing pretrained deep networks with classical machine learning methods.

RESUMO

BACKGROUND: In patients with non-transfusion-dependent ß-thalassaemia, haemoglobin concentrations lower than 10 g/dL are associated with a higher risk of morbidity, mortality, and impaired quality of life. No drugs are specifically approved for anaemia management in patients with non-transfusion-dependent ß-thalassaemia, other than transfusion therapy administered infrequently in accordance with patients' needs. We assessed the efficacy and safety of luspatercept versus placebo in patients with non-transfusion-dependent ß-thalassaemia. METHODS: We did a phase 2, randomised, double-blind, multicentre, placebo-controlled trial in 12 centres in six countries (Thailand [n=1], Lebanon [n=1], Greece [n=2], Italy [n=5], the UK [n=1], and the USA [n=2]). Eligible patients were aged 18 years or older, had confirmed diagnosis of ß-thalassaemia or haemoglobin E/ß-thalassaemia (concomitant α-globin deletion, mutation, or duplication were allowed), and a baseline haemoglobin concentration of 10·0 g/dL or lower. All patients were non-transfusion-dependent. Patients were randomly assigned (2:1) to luspatercept or placebo using an interactive response technology system and stratified by baseline haemoglobin concentration (≥8·5 g/dL vs <8·5 g/dL) and baseline Non-Transfusion-Dependent ß-thalassaemia-Patient-Reported Outcome Tiredness/Weakness domain score (≥3 vs <3). All patients, study site staff, and sponsor representatives (who reviewed the data), except for designated individuals, were masked to drug assignment until the time the study was unblinded. Luspatercept or placebo was given once subcutaneously every 3 weeks for 48 weeks in the double-blind treatment period. Luspatercept was started at 1·0 mg/kg with titration up to 1·25 mg/kg, or reduction in the event of toxicity or excessive haemoglobin concentration increase. The primary endpoint was achievement of an increase from baseline of 1·0 g/dL or higher in mean haemoglobin concentration over a continuous 12-week interval during weeks 13-24, in the absence of transfusions. The primary efficacy and safety analyses were done in the intention-to-treat population. This trial is registered at ClinicalTrials.gov, NCT03342404, and is ongoing. FINDINGS: Between Feb 5, 2018, and Oct 14, 2019, 160 patients were screened for eligiblity, of whom 145 were randomly assigned to luspatercept (n=96) or placebo (n=49). 82 (57%) patients were female and 63 (43%) were male. 44 (30%) patients were Asian, 87 (60%) were White, and 14 (10%) identified as another race. The study met its primary endpoint: 74 (77%) of 96 patients in the luspatercept group and none in the placebo group had an increase of at least 1·0 g/dL in haemoglobin concentration (common risk difference 77·1 [95% CI 68·7-85·5]; p<0·0001). The proportion of patients with serious adverse events was lower in the luspatercept group than in the placebo group (11 [12%] vs 12 [25%]). Treatment-emergent adverse events most commonly reported with luspatercept were bone pain (35 [37%]), headache (29 [30%]), and arthralgia (28 [29%]). No thromboembolic events or deaths were reported during the study. INTERPRETATION: Luspatercept represents a potential treatment for adult patients with non-transfusion-dependent ß-thalassaemia, for whom effective approved treatment options are scarce.

RESUMO

Among the difficulties of living with ß-thalassemia, patients frequently require blood transfusions and experience iron overload. As serum ferritin (SF) provides an indication of potential iron overload, we conducted a systematic literature review (SLR) to assess whether SF levels are associated with clinical and economic burden and patient-reported outcomes (PROs). The SLR was conducted on 23 April 2020 and followed by analysis of the literature. Dual-screening was performed at the title, abstract, and full-text levels using predefined inclusion and exclusion criteria. Ten studies identified by the SLR were eligible for inclusion in the analysis. Seven studies were conducted in Europe, and most were prospective or retrospective in design. The patient populations had a median age of 20.7-42.6 years, with a percentage of men of 38-80%. Sparse data were found on the correlation between SF levels and mortality, and hepatic, skeletal, and cardiac complications; however, in general, higher SF levels were associated with worsened outcomes. The bulk of the evidence reported on the significant association between higher SF levels and endocrine dysfunction in its many presentations, including a 14-fold increase in the risk of diabetes for patients with persistently elevated SF levels. No studies reporting data on PROs or economic burden were identified by the SLR. SF levels provide another option for prognostic assessment to predict a range of clinical outcomes in patients with ß-thalassemia.

RESUMO

BACKGROUND: This study aimed to evaluate the nutritional status and body composition in children with cystic fibrosis (CF), in accordance with the new nutritional targets defined by European Society for Clinical Nutrition and Metabolism (ESPEN), the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the European Cystic Fibrosis Society (ECFS) 2016. METHODS: In this cross-sectional study, data were collected prospectively in a single centre. A record was made for a total of 95 patients with CF of clinical data. Anthropometric data were evaluated using the World Health Organization growth standards. The bone mineral density (BMD) z-score was adjusted for height by measuring dual-energy X-ray absorptiometry (DXA). The speed of sound z-score values were measured with quantitative ultrasound (QUS). RESULTS: The nutritional status was normal in 37.9% of patients aged < 2 years and 33.3% of patients aged 2-18 years. When the DXA BMD z-score values were corrected for height, it was determined that the BMD deficit was less. The calcaneus QUS SOS z-score mean value was lower than the mean height for age z-score adjusted BMD (BMDHAZ). CONCLUSIONS: The malnutrition rates of CF patients were higher than the rates previously reported in literature. As there are insufficient nutritional data in Turkey, there is a need for multi-centre studies to determine the frequency of malnutrition according to the new classifications. It is clear that QUS measurements cannot replace DXA in the diagnosis of osteopenic bone disease. However, when low values are determined with QUS as the first recommended measurement in the screening of bone status, it can be considered appropriate to confirm the status with DXA.

RESUMO

Anemia is the most common form of cytopenia in patients with myelodysplastic syndromes (MDS), who require chronic red blood cell transfusions and may present high serum ferritin (SF) levels as a result of iron overload. To better understand the potential effects of high SF levels, we conducted a systematic literature review (SLR) to identify evidence on the relationship between SF levels and clinical, economic, or humanistic outcomes in adult patients with MDS. Of 267 references identified, 21 were included. No studies assessing SF levels and their relationship with humanistic or economic outcomes were identified. Increased SF levels were an indicator of worse overall survival and other worsened outcomes; however, the association was not consistently significant. SF levels were a significant prognostic factor for relapse incidence of MDS and showed a significant positive correlation with number of blood units transfused but were not associated with progression to acute myeloid leukemia or the time to transformation. Higher SF levels were also an indicator of a lower likelihood of leukemia-free survival, relapse-free survival, and event-free survival. The SLR suggests that SF levels are associated with clinical outcomes in MDS, with higher levels correlated with number of blood units transfused, frequently indicating worse outcomes.

RESUMO

BACKGROUND: Several options for granulocyte colony-stimulating factor (G-CSF) prophylaxis of chemotherapy-induced febrile neutropenia are available to patients worldwide. We have developed a novel patient-reported outcome measure, the Satisfaction and Experience Questionnaire for G-CSF (SEQ-G-CSF), to help understand patients' perspectives of and satisfaction with different G-CSF options. RESULTS: Three oncology nurses and 40 adult oncology patients in the United States were enrolled and participated in focus group discussions to develop and refine the SEQ-G-CSF. Nurses had ≥ 5 years of experience treating oncology patients and were currently involved in the management of oncology patients receiving G-CSF prophylaxis. The patients had breast cancer, lung cancer, non-Hodgkin lymphoma, or prostate cancer (10 patients in each group) and were receiving G-CSF prophylaxis via injection or the on-body injector (OBI) device. The preliminary SEQ-G-CSF contained an item relevance questionnaire and three SEQ modules (sociodemographic, medical history, and G-CSF-related healthcare characteristics questionnaires). Twenty-one patients (53% of total sample size) discussed their experience and satisfaction with G-CSF. Their most common experiences were G-CSF effectiveness, convenience and benefits of the OBI, and relationships with healthcare providers. Side effects and having to undergo additional treatment were also reported. Satisfaction with aspects of G-CSF included the OBI and effectiveness of G-CSF treatment; dissatisfaction included inconvenience (having to return to the clinic the next day and administration of the injection) and the insurance approval process. The SEQ-G-CSF was finalized after three rounds of cognitive interviews and includes five domains related to general satisfaction (one item), treatment burden (four items), travel burden (two items), time burden (four items), and treatment compliance (two items). CONCLUSIONS: The SEQ-G-CSF is a novel instrument that quantifies a patient's experience and satisfaction with different G-CSF options using 13 easy-to-understand items. This study provides evidence for the content validity of SEQ-G-CSF. Although further psychometric testing is required, the SEQ-G-CSF may be a useful addition to clinical trials, observational studies, and clinical practice.

RESUMO

Migraine is a leading cause of disability globally. Individuals with migraine experience reduced work productivity and greater health care costs compared with the general population. The Migraine Impact Model (MIM) is an interactive calculator developed to estimate the economic burden of migraine on United States-based employers. We demonstrate use of the model with 4 case studies from different industries (education, manufacturing, retail/trade, and entertainment). The MIM estimates migraine prevalence among employees and the employer's annual migraine-associated costs by applying published, licensed, and publicly available data and several underlying assumptions to employee population information that is inputted by users. User inputs include the employer's industry, geographic location, and workforce characteristics (number of employees, gender distribution, and average age and compensation). Model outputs include estimated migraine prevalence, annual workdays affected by migraine, and annual migraine-associated indirect and direct costs to the employer. In the case studies presented, workforce size ranged from 18,800 to 250,000, representing midsized to larger employers. Employee gender distribution ranged from 29% to 74% women, and mean employee age was either 41 or 44 years. The model-estimated percentage of employees with migraine ranged from 14% to 19%. The model projected approximately 60,000 to 686,000 annual workdays to be affected by lost productive time due to migraine (often referred to as "absenteeism" and "presenteeism") and estimated annual indirect costs to total between 6.2 and 8.5 times the annual direct costs. The MIM estimates the economic burden of migraine on a company's workforce, which may aid employers in making data-driven decisions to reduce that burden for employees and business.

RESUMO

OBJECTIVES: To compare the racial/ethnic differences in treatment quality among youth with primary care provider-initiated versus mental health specialist-initiated care for major depressive disorders (MDD). METHODS: A retrospective cohort study was conducted using the 2005-2007 Medicaid claims data from Texas. Youth aged 10-20 during the study period were identified if they had two consecutive MDD diagnoses and received either medications for MDD or psychotherapy. Patients who received ≥84 days of medications and/or ≥4 sessions of psychotherapy for MDD treatment during 4 months of follow-up were considered meeting the minimum adequacy of treatment. RESULTS: The generalized linear multilevel model (MLM) analysis revealed that both Hispanics and Blacks were approximately 30% less likely to receive adequate treatment (Hispanics - OR: 0.67; 95% CI: 0.6-0.8) (Blacks - OR: 0.66; 95% CI: 0.6-0.8) and Hispanic children were 50% more likely to undergo MH-related hospitalization (OR: 1.53; 95% CI: 1.1-2.2) compared to their White counterparts. The odds of meeting the minimum MDD treatment adequacy were comparable between pediatric MDD cases first identified by primary care providers (PCP-I) and psychiatrists (PSY-I) (PCP-I vs. PSY-I: OR: 0.97; 95% CI: 0.8-1.2), and slightly lower in those first identified by social workers/psychologists (SWP-I) as compared to PSY-I (SWP-I vs. PSY-I: OR: 0.81; 95% CI: 0.7-0.9). In all models, the interaction between race/ethnicity and type of provider who initiated MDD care was not statistically significant. CONCLUSIONS: Minority youths received less adequate MDD treatment compared to Whites. Hispanic children had the highest risk of having mental health-related hospitalization. The specialty of provider who initiated MDD care had limited impact on treatment quality and was not associated with the racial/ethnic variations in treatment completion and mental health-related hospitalizations.

RESUMO

Background/aim: Mesenteric panniculitis (MP) is an idiopathic benign disease characterized by fat necrosis, chronic inflammation, and fibrosis. The relationship between obesity and chronic low-grade inflammation has been reported. This study investigated the relationship of MP diagnosed using multidetector computed tomography (MDCT) with visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) areas. Materials and methods: We retrospectively enrolled 104 patients with no radiological findings other than MP. Additionally, 76 individuals without any indicative radiological findings were included as controls. VAT and SAT were separately calculated (cm2) using a 3-dimensional workstation. The abdominal circumference was measured (cm). Results: The mean abdominal circumference was 99.9 ± 7.9 cm, SAT was 195.3 ± 89.1 cm2, and VAT was 203.9 ± 72.8 cm2 in the MP group. The abdominal circumference, VAT, and SAT were significantly higher in the MP group than in the control group (P < 0.001). According to the receiver operating characteristic (ROC) analysis, cut-off level VAT and SAT were 167.5 cm2 (sensitivity 71%, specificity 69%) and 117.5 cm2 (sensitivity 78%, specificity 51 %), respectively. Conclusion: Increased VAT and SAT were associated with MP, suggesting their role in the etiology of MP.

RESUMO

OBJECTIVES: Febrile neutropenia (FN) is a life-threatening complication of chemotherapy that can lead to hospitalizations, chemotherapy dose reductions or delays, and mortality. Granulocyte colony-stimulating factor (G-CSF) prophylaxis reduces the incidence of FN, enabling patients to undergo and remain on myelosuppressive chemotherapy. We estimate the benefits of continuing current G-CSF use patterns and an alternative that aligns prophylactic G-CSF use with guideline recommendations. STUDY DESIGN: Using The Health Economics Medical Innovation Simulation microsimulation, we estimated lifetime social value (SV) of prophylactic G-CSF for a nationally representative US population with breast, lung, and gynecological cancers and non-Hodgkin lymphoma. METHODS: SV estimates included the cost of G-CSF, FN, chemotherapy relative dose intensity (RDI) less than 85% (RDI<85%), medical spending, and deaths for 3 scenarios: current use (current G-CSF use), targeted use (100% G-CSF use among patients with high FN risk), and reduced use (current G-CSF use reduced by 20% across all FN risk categories). RESULTS: Over 10 years, current use, compared with no G-CSF use, would decrease cases of FN by 3.3 million, prevent 354,000 cases of RDI<85%, and generate $96 billion in SV. Compared with current use, targeted use would decrease cases of FN by an additional 3.3 million, prevent 355,000 more cases of RDI<85%, and generate another $119 billion in SV. Reduced use would increase FN and RDI<85%, lowering SV by $18 billion compared with current use. CONCLUSIONS: Current use of G-CSF prophylaxis would provide $96 billion in SV over the next 10 years. Targeting G-CSF prophylaxis to align with guidelines would more than double SV, highlighting the substantial value of appropriate FN risk assessment and targeted G-CSF prophylaxis.

RESUMO

Background and Objective: Malnutrition is a major complication of inflammatory bowel disease (IBD). Our aim of the study was to examine the effects of Modulen IBD supplementation, which was administered to IBD patients without limiting their daily diet in addition to medical treatment, on the clinical, laboratory, anthropometric values, and disease activities of these patients. Materials and Methods: Seventy three children with IBD were evaluated retrospectively. The cases were classified as those who had Crohn disease receiving (CD-M; n = 16) or not receiving Modulen IBD (CD; n = 19) and those who had ulcerative colitis receiving (UC-M; n = 13) or not receiving Modulen IBD (UC; n = 25). Disease activities, laboratory values, remission rates, and anthropometric measurements of the groups were compared. In addition to IBD treatment, Modulen IBD in which half of the daily calorie requirement was provided was given for eight weeks. Results: In the third month of treatment, 14 (88%) patients were in remission in CD-M group and eight (42%) patients were in remission in CD group. The height and weight z scores, which were low at the time of diagnosis, improved in the first week in CD-M group. Inflammatory parameters (UC) were significantly lower in the UC-M group compared to the UC group in first and third months. In the third month, eight (62%) patients in the UC-M group and four (16%) in the UC group were remitted clinically and in terms of laboratory values. Conclusions: TGF-ß-rich enteral nutrition support in children with IBD is an easy, effective, and reliable approach. It was shown that TGF-ß-rich enteral nutritional supplementation enabled the disease to enter the remission earlier, and contributed to the early recovery of weight and height scores.

RESUMO

BACKGROUND: Mistaken ingestion of all manner of toxic matter is common in childhood, but poisoning with fireworks and matchsticks is rare. Fireworks usually contain 10% yellow phosphorus and 50% potassium chlorate. Potassium chlorate is an extremely reactive and toxic agent that is used in fireworks and matchstick heads. METHODS: Eleven cases (7 females and 5 males; median age, 36 months [ranging from 24 to 48 months]) of poisoning after ingestion of fireworks and matchstick(s), between February 2008 and June 2014, were reviewed. RESULTS: The most common initial symptom was vomiting except for 2 cases in this group. Biochemical tests indicated that hyperphosphatemia was present in all patients, 8 patients (72.7%) had subclinical hepatic injury, 1 (9%) had acute hepatic failure, and 2 patients had no clinical or biochemical evidence of hepatic damage. Three patients had renal impairment, but none of them required dialysis. All of the patients recovered with supportive therapy except for 2 cases. One patient underwent cadaveric liver transplantation, whereas the other died because of circulatory dysfunction and respiratory failure due to pulmonary alveolar hemorrhage. CONCLUSIONS: Without prompt intervention, poisoning with fireworks carries high morbidity and mortality in children. It can cause pulmonary hemorrhage, in addition to other organ damage, including liver and kidney. Hyperphosphatemia is common, as it was seen in all of the study patients.

RESUMO

Many patients with lower-risk myelodysplastic syndrome (MDS) experience anaemia, which has negative consequences. Erythropoiesis-stimulating agents (ESAs) and their biosimilars are used to treat anaemia in MDS and, currently, epoetin alfa and darbepoetin alfa are commonly used and recommended by clinical guidelines. To better understand the evidence available on the use of ESAs for anaemia in lower-risk MDS, we conducted a systematic literature review to identify randomized and nonrandomized prospective studies reporting on clinical efficacy/effectiveness, patient-reported quality of life (QoL), and safety. We extended our review to include retrospective studies for darbepoetin alfa specifically and to ascertain the feasibility of completing an indirect network meta-analysis comparing epoetin and darbepoetin alfa. Overall, 53 articles reporting on 35 studies were included. The studies indicated a clinical benefit of ESAs, with benefits observed across key clinical outcomes. ESAs showed consistent improvement in erythroid response rates (ESA-naïve, 45-73%; previous ESA exposure, 25-75%) and duration of response. Comparative studies demonstrated similar progression to acute myeloid leukaemia and several showed improved overall survival and QoL. Limited safety concerns were identified. This analysis confirmed ESA therapy should be the foremost first-line treatment of anaemia in most patients with lower-risk MDS who lack the 5q deletion.

RESUMO

BACKGROUND: To examine whether racial/ethnic differences in receipt of MDD treatment could be explained by the specialty of provider diagnosing the adolescent. METHOD: Adolescents (10-20 years-old) with ≥2 MDD diagnoses were identified using 2005-2007 Medicaid data from Texas. Patients were categorized based on the types of provider who gave the initial MDD diagnosis (psychiatrist (PSY-I), social worker/psychologist (SWP-I), and primary care physician (PCP-I)). Within the sub-cohorts identified by each type of provider, patients were further divided by racial/ethnic groups. RESULTS: Of the 13,234-new pediatric MDD cases diagnosed, 61% were SWP-I, 33% PSY-I and 6% PCP-I. Results of the analysis using general linear multi-level model showed that being first diagnosed by a psychiatrist was associated with higher chance of receiving MDD related treatment (PCP-I vs. PSY-I (OR: 0.54, 95%CI: 0.4-0.7) and SWP-I vs. PSY-I (OR: 0.17, 95%CI: 0.1-0.2)). Specifically, regarding the receipt of pharmacotherapy, an interaction effect was detected between types of identifying providers and patients' race/ethnicity. The analysis stratified by race/ethnicity found Whites received comparable treatment regardless being PCP-Is or PSY-Is, while for Hispanics, being first identified by a PCP was associated with lower likelihood of receiving treatment as compared to being first identified by a psychiatrist. Further analysis stratified by provider types showed that a significant racial/ethnic variation in medication utilization was observed in PCP-Is, but not in PSY-Is. CONCLUSION: For adolescents with MDD, being first diagnosed by a psychiatrist was associated with higher treatment rate and reduced racial/ethnic variation in the utilization of pharmacotherapy.
