Preliminary comparision between phalangeal quantitative ultrassonography and bone densitometry for bone mass evaluation in adolescents
OBJECTIVE: To evaluate the association between quantitative ultrasonography at hand phalanges (QUS) and dual energy X-ray absorptiometry (DXA), and between these methods with food intake and history of bone fractures. SUBJECTS AND METHODS:After two years of follow up of 270 schoolchildren, 10 of them, who showed bone mass below - 2 SD in QUS, were included in the present study. Laboratory results and DXA data were analyzed. RESULTS: Bone mass evaluated by DXA at L1-L4 ranged from -2.8 to -1.1 SDS, and whole body bone mass, from -2.9 to -1.2 SDS. Three children had history of non-pathological bone fractures. Dietary assessment showed low intake of calcium in 10 cases, of phosphorus in 6, and of vitamin D in 8 cases. There were no differences among the cases of bone mass below-2 SD in any of the three used methods. There was no association between history of bone fractures and food intake, and between these evaluations and bone mass. CONCLUSION: In this small group of schoolchildren there was an association between the methods QUS and DXA. However, there was no association between bone mass and the history of bone fractures, or calcium, phosphorus and vitamin D intake.OBJETIVO: Avaliar associação entre ultrassonografia quantitativa de falanges da mĂŁo (QUS) e a densitometria por absorção de raio-X de dupla energia (DXA) e desses com os histĂłricos alimentar e de fraturas. SUJEITOS E MĂTODOS: ApĂłs dois anos de acompanhamento de 270 escolares, 10 com massa Ăłssea por QUS abaixo de -2 DP foram incluĂdos no estudo e avaliados com DXA. RESULTADOS: A massa Ăłssea por DXA de L1-L4 variou de -2,8 a -1,1 DP e de corpo inteiro -2,9 e -1,2. TrĂȘs estudantes apresentaram fraturas. Baixa ingestĂŁo de cĂĄlcio foi observada nos 10 casos, de fĂłsforo em 6 e de vitamina D em 8. NĂŁo houve diferença entre os casos com massa abaixo de -2 DP nos trĂȘs mĂ©todos de avaliação. NĂŁo foi observada associação entre as fraturas e o histĂłrico alimentar, nem com os valores de massa Ăłssea. CONCLUSĂO: Neste pequeno grupo de adolescentes houve associação entre QUS e DXA, porĂ©m sem associação entre essas avaliaçÔes e as fraturas e a ingestĂŁo de cĂĄlcio, fĂłsforo e vitamina D.1924Conselho Nacional de Desenvolvimento CientĂfico e TecnolĂłgico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de NĂvel Superior (CAPES
Insulin Resistance in HIV-Patients: Causes and Consequences
Here we review how immune activation and insulin resistance contribute to the metabolic alterations observed in HIV-infected patients, and how these alterations increase the risk of developing CVD. The introduction and evolution of antiretroviral drugs over the past 25 years has completely changed the clinical prognosis of HIV-infected patients. The deaths of these individuals are now related to atherosclerotic CVDs, rather than from the viral infection itself. However, HIV infection, cART, and intestinal microbiota are associated with immune activation and insulin resistance, which can lead to the development of a variety of diseases and disorders, especially with regards to CVDs. The increase in LPS and proinflammatory cytokines circulating levels and intracellular mechanisms activate serine kinases, resulting in insulin receptor substrate-1 (IRS-1) serine phosphorylation and consequently a down regulation in insulin signaling. While lifestyle modifications and pharmaceutical interventions can be employed to treat these altered metabolic functions, the mechanisms involved in the development of these chronic complications remain largely unresolved. The elucidation and understanding of these mechanisms will give rise to new classes of drugs that will further improve the quality of life of HIV-infected patients, over the age of 50
Hypoalbuminemia as a risk factor for thromboembolic events in inflammatory bowel disease inpatients
Background/Aims Inflammatory bowel disease (IBD) are chronic entities characterized by local and systemic inflammation and may be associated with thrombosis. The aim of this study was to identify the prevalence of thromboembolic events (TEE) in hospitalized IBD patients and identify risk factors for their occurrence. Methods This retrospective, single-center study included patients treated at a Brazilian IBD referral unit between 2004 and 2014. Patients hospitalized for more than 48 hours due to active IBD and who did not receive prophylaxis for TEE during hospitalization were included. Patients were allocated to 2 groups: those with TEE up to 30 days or at the time of hospitalization (TEE-group) and patients without TEE (control-group). Clinical and laboratory characteristics were evaluated. Results Of 53 patients evaluated, 69,8% with Crohnâs disease (CD) and 30.2% with ulcerative colitis (UC). The prevalence of TEE 30 days before or during hospitalization was 15.1%, with 10.8% in CD and 25% in UC. In the TEE group, mean serum albumin was 2.06 g/dL versus 3.30 g/dL in the control group. Patients with albumin levels below 2.95 g/dL (43.18%) had a higher risk of developing TEE (relative risk, 1.72; 95% confidence interval, 1.17â2.53) (P<0.001). Conclusions Albumin levels were significantly lower in patients with TEE, and hypoalbuminemia was considered a risk factor for the development of TEE in this population
High frequency of Fredrickson's phenotypes IV and IIb in Brazilians infected by human immunodeficiency virus
BACKGROUND: Human immunodeficiency virus (HIV) infection is very prevalent in Brazil. HIV therapy has been recently associated with coronary heart disease (CHD). Dyslipidemia is a major risk factor for CHD that is frequently described in HIV positive patients, but very few studies have been conducted in Brazilian patients evaluating their lipid profiles. METHODS: In the present work, we evaluated the frequency and severity of dyslipidemia in 257 Brazilian HIV positive patients. Two hundred and thirty-eight (93%) were submitted to antiretroviral therapy (224 treated with protease inhibitors plus nucleoside reverse transcriptase inhibitors, 14 treated only with the latter, 12 naive and 7 had no records of treatment). The average time on drug treatment with antiretroviral therapy was 20 months. None of the patients was under lipid lowering drugs. Cholesterol, triglyceride, phospholipid and free fatty acids were determined by enzymatic colorimetric methods. Lipoprotein profile was estimated by the Friedewald formula and Fredrickson's phenotyping was obtained by serum electrophoresis on agarose. Apolipoprotein B and AI and lipoprotein "a" were measured by nephelometry. RESULTS: The Fredrickson phenotypes were: type IIb (51%), IV (41%), IIa (7%). In addition one patient was type III and another type V. Thirty-three percent of all HIV+ patients presented serum cholesterol levels â„ 200 mg/dL, 61% LDL-cholesterol â„ 100 mg/dL, 65% HDL-cholesterol below 40 mg/dL, 46% triglycerides â„ 150 mg/dL and 10% have all these parameters above the limits. Eighty-six percent of patients had cholesterol/HDL-cholesterol ratio â„ 3.5, 22% increased lipoprotein "a", 79% increased free fatty acids and 9% increased phospholipids. The treatment with protease inhibitors plus nucleoside reverse transcriptase inhibitors increased the levels of cholesterol and triglycerides in these patients when compared with naĂŻve patients. The HDL-cholesterol (p = 0.01) and apolipoprotein A1 (p = 0.02) levels were inversely correlated with the time of protease inhibitor therapy while total cholesterol levels had a trend to correlate with antiretroviral therapy (p = 0.09). CONCLUSION: The highly varied and prevalent types of dyslipidemia found in Brazilian HIV positive patients on antiretroviral therapies indicate the urgent need for their early diagnosis, the identification of the risk factors for CHD and, when needed, the prompt intervention on their lifestyle and/or with drug treatment
Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprungâs disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprungâs disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36â39) and median bodyweight at presentation was 2·8 kg (2·3â3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
pâ€0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88â4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59â2·79], p<0·0001), sepsis at presentation (1·20
[1·04â1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4â5 vs ASA 1â2, 1·82 [1·40â2·35], p<0·0001; ASA 3 vs ASA 1â2, 1·58, [1·30â1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02â1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41â2·71], p=0·0001; parenteral nutrition 1·35, [1·05â1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47â0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50â0·86], p=0·0024) or percutaneous central line (0·69 [0·48â1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Omecamtiv mecarbil in chronic heart failure with reduced ejection fraction, GALACTICâHF: baseline characteristics and comparison with contemporary clinical trials
Aims:
The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTICâHF) trial. Here we describe the baseline characteristics of participants in GALACTICâHF and how these compare with other contemporary trials.
Methods and Results:
Adults with established HFrEF, New York Heart Association functional class (NYHA)ââ„âII, EF â€35%, elevated natriuretic peptides and either current hospitalization for HF or history of hospitalization/ emergency department visit for HF within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokineticâguided dosing: 25, 37.5 or 50âmg bid). 8256 patients [male (79%), nonâwhite (22%), mean age 65âyears] were enrolled with a mean EF 27%, ischemic etiology in 54%, NYHA II 53% and III/IV 47%, and median NTâproBNP 1971âpg/mL. HF therapies at baseline were among the most effectively employed in contemporary HF trials. GALACTICâHF randomized patients representative of recent HF registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressureâ<â100âmmHg (n = 1127), estimated glomerular filtration rate <â30âmL/min/1.73 m2 (n = 528), and treated with sacubitrilâvalsartan at baseline (n = 1594).
Conclusions:
GALACTICâHF enrolled a wellâtreated, highârisk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation
Risk factors that influence the prognosis of community-acquired pneumonia in hospitalized adults
OBJECTIVE: The present study assessed the influence of nutritional parameters on the prognosis of community-acquired pneumonia in adults admitted to a general hospital. METHODS: A total of 61 individuals with community-acquired pneumonia were studied prospectively and the following data analyzed: sociodemographic variables, morbidity, life habits, anthropometric variables (body mass index, waist circumference, percentage of body fat, percentage of weight lost), biochemical variables (urea, creatinine, albumin on admission and 18 days later, prealbumin on admission and 4, 8 and 18 days later), and outcome (hospital stay shorter than 10 days, longer than 10 days and/or death). RESULTS: Anthropometric variables differed between genders but were not associated with poor outcome. Albumin and prealbumin levels were low on admission in 80.3% and 86.9% of the cases, respectively. Logistic regression showed that smoking (OR:1.23; CI:1.0-12.1), more than one finding or pleural effusion on chest radiographs (OR:1.4; CI:1.24-15.3) and low prealbumin on day 4 (OR:6.1; CI:1.7-22.5) predicted a poor outcome for patients with community-acquired pneumonia. CONCLUSION: Nutrition-related biochemical markers, such as low prealbumin, smoking and more than one finding on chest radiographs, indicate severe pneumonia and are useful for deciding treatment strategy.OBJETIVO: Avaliar parĂąmetros nutricionais no prognĂłstico de adultos internados em hospital geral, com pneumonia adquirida na comunidade. MĂTODOS: Foram estudados prospectivamente 61 casos da doença e analisadas variĂĄveis: sociodemogrĂĄficas, morbidade, hĂĄbitos de vida, antropomĂ©tricas (Ăndice de massa corporal, circunferĂȘncia da cintura, porcentagem de gordura, porcentagem de perda de peso), bioquĂmicas (ureia, creatinina, albumina no momento da internação e no 18Âș dia e prĂ©-albumina (na internação, quarto, oitavo e 18Âș dia) e evolução (menos de 10, mais de 10 dias de internação e/ou Ăłbito). RESULTADOS: As variĂĄveis antropomĂ©tricas apresentaram-se diferentes entre os sexos, porĂ©m nĂŁo se associaram com a mĂĄ evolução da doença. Os nĂveis sĂ©ricos de albumina e de prĂ©-albumina encontraram-se baixos na internação em 80,3% e 86,9% dos casos, respectivamente. ApĂłs ajuste logĂstico, o hĂĄbito de fumar (OR:1,23, IC:1,0-12,1), a presença de mais de uma imagem ou derrame pleural no exame radiolĂłgico de tĂłrax (OR: 1,4 IC: 1,24-15,3) e a prĂ©-albumina baixa no quarto dia (OR:6,1 IC:1,7-22,5) foram preditores de mĂĄ evolução do quadro de pacientes com pneumonia adquirida na comunidade. CONCLUSĂO: Indicador bioquĂmico nutricional como a prĂ©-albumina, o tabagismo e mais de uma imagem no exame radiolĂłgico de tĂłrax sĂŁo parĂąmetros de gravidade de pneumonia Ășteis na condução clĂnica de infecçÔes.23724
