Roles of the Taql and Bsml vitamin D receptor gene polymorphisms in hospital mortality of burn patients

OBJECTIVE: The aim of this study was to evaluate the roles of the Taql and Bsml vitamin D receptor gene polymorphisms in hospital mortality of burn patients. METHODS: In total, 105 consecutive burn injury patients over 18 years in age who were admitted to the Burn Unit of Bauru State Hospital from January to December 2013 were prospectively evaluated. Upon admission, patient demographic information was recorded and a blood sample was taken for biochemical analysis to identify the presence of the Taql(rs731236) and Bsml(rs1544410) polymorphisms. All of the patients were followed over their hospital stay and mortality was recorded. RESULTS: Eighteen of the patients did not sign the informed consent form, and there were technical problems with genotype analysis for 7 of the patients. Thus, 80 patients (mean age, 42.5±16.1 years) were included in the final analysis. In total, 60% of the patients were male, and 16.3% died during the hospital stay. The genotype frequencies for the Taql polymorphism were 51.25% TT, 41.25% TC and 7.50% CC; for the Bsml polymorphism, they were 51.25% GG, 42.50% GA and 6.25% AA. In logistic regression analysis, after adjustments for age, gender and total body surface burn area, there were no associations between the Taql (OR: 1.575; CI95%: 0.148-16.745; p=0.706) or Bsml (OR: 1.309; CI95%: 0.128-13.430; p=0.821) polymorphisms and mortality for the burn patients. CONCLUSIONS: Our results suggest that the Taql and Bsml vitamin D receptor gene polymorphisms are not associated with hospital mortality of burn patients

Quality of life after on-pump and off-pump coronary artery bypass grafting surgery

FUNDAMENTO: Técnicas de cirurgia de revascularização miocárdica (RM) sem o uso de circulação extracorpórea (CEC) possibilitou resultados operatórios com menor dano sistêmico, menor ocorrência de complicações clínicas, menor permanência na sala de terapia intensiva e também no tempo de internação, gerando expectativas de melhor qualidade de vida (QV) dos pacientes. OBJETIVO: Avaliar a QV em pacientes submetidos à cirurgia de revascularização com e sem CEC. MÉTODOS: Em pacientes com doença multiarterial coronariana (DAC) estável e função ventricular preservada, aplicou-se o Short-Form Health Survey (SF-36) Questionnaire antes da cirurgia e depois de 6 e 12 meses. RESULTADOS: Entre janeiro de 2002 e dezembro de 2006, foram randomizados 202 pacientes para cirurgia de RM. As características demográficas clínicas laboratoriais e angiográficas foram semelhantes nos dois grupos. Desses pacientes, 105 foram operados sem CEC e 97 com CEC. Na evolução, 22 pacientes sofreram infarto, 29 relataram angina, um reoperou, 3 tiveram AVC e nenhum morreu. A avaliação da QV mostrou similaridade nos dois grupos em relação ao componente físico e mental. Todavia, encontrou-se significativa melhora da capacidade funcional e percepção do aspecto físico nos pacientes do sexo masculino. Além disso, um expressivo número de pacientes dos dois grupos retornou ao trabalho. CONCLUSÃO: Em todos os pacientes estudados, observaram-se melhora progressiva da qualidade de vida e retorno precoce ao trabalho, independentemente da técnica cirúrgica empregada. Exceto pela melhor percepção da capacidade funcional e do aspecto físico experimentado pelos homens, não houve diferença estatística nos resultados dos demais domínios alcançados pelos dois grupos estudados.BACKGROUND: Coronary artery bypass grafting techniques without using cardiopulmonary bypass (off-pump CABG) result in less systemic damage, less clinical complications, less time spent in the intensive care unit, and shorter hospital stays, thereby raising the perspective of improved quality of life (QOL) for patients. OBJECTIVE: To assess quality of life in patients who underwent on-pump and off-pump CABG. METHODS: The Short-Form Health Survey (SF-36) Questionnaire was administered to patients with stable multivessel coronary artery disease (CAD) and preserved ventricular function before and at six and 12 months after surgery. RESULTS: Between January 2002 and December 2006, a total of 202 patients were randomized to either on-pump or off-pump CABG. Demographic, clinical, laboratory, and angiographic characteristics were similar in both groups. One hundred and five patients underwent off-pump CABG and 97 underwent on-pump CABG. In the postoperative course, 22 patients had myocardial infarction, 29 reported angina, one was reoperated, and three experienced stroke. No patient died. Quality of life, as measured by the SF-36 questionnaire, was shown to be similar in both groups regarding physical and mental components. However, male patients showed a significant improvement in physical functioning and role limitations due to physical problems. Also, a large number of patients in both groups returned to work. CONCLUSION: Progressive enhancement in quality of life and early return to work were observed for all patients, regardless of the surgical technique used. Save for a greater improvement in physical functioning and role limitations due to physical problems experienced by male patients, no statistically significant differences were found in the other domains between groups

Histopathological Characterization and Whole Exome Sequencing of Ectopic Thyroid: Fetal Architecture in a Functional Ectopic Gland from Adult Patient

Ectopic thyroid results from a migration defect of the developing gland during embryogenesis causing congenital hypothyroidism. But it has also been detected in asymptomatic individuals. This study aimed to investigate the histopathological, functional, and genetic features of human ectopic thyroids. Six samples were histologically examined, and the expression of the specific thyroid proteins was assessed by immunohistochemistry. Two samples were submitted to whole exome sequencing. An oropharynx sample showed immature fetal architecture tissue with clusters or cords of oval thyrocytes and small folliclesone sample exhibited a normal thyroid pattern while four showed colloid goiter. All ectopic thyroids expressed the specific thyroid genes and T4 at similar locations to those observed in normal thyroid. No somatic mutations associated with ectopic thyroid were found. This is the first immature thyroid fetal tissue observed in an ectopic thyroid due to the arrest of structural differentiation early in the colloid stage of development that proved able to synthesize thyroid hormone but not to respond to TSH. Despite the ability of all ectopic thyroids to synthetize specific thyroid proteins and T4, at some point in life, it may be insufficient to support body growth leading to hypothyroidism, as observed in some of the patients.FAPESP Grant [2009/53840-0]Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Sao Paulo, Brazil [2010/12005-9, 2014/24549-4]Instituto da TiroideUniv Sao Paulo FMUSP, Fac Med, Cellular & Mol Endocrine Lab, Thyroid Unit,LIM 25, Ave Doutor Arnaldo 455, BR-01246904 Sao Paulo, SP, BrazilSao Paulo Publ Hlth Serv, Adolfo Lutz Inst, Av Dr Arnaldo 355, BR-01246000 Sao Paulo, SP, BrazilHead & Neck Surg Santa Catarina Hosp, Av Paulista 200, BR-01310000 Sao Paulo, SP, BrazilUNESP, Botucatu Sch Med, Dept Internal Med, Av Prof Montenegro,S-N Dist Rubiao Jr, BR-18618687 Botucatu, SP, BrazilHosp Pediat Dr Juan Garrahan, Serv Endocrinol, Combate Pozos 1881,C1245AAM, Buenos Aires, DF, ArgentinaUniv Estadual Campinas, Fac Ciencias Med, Dept Cirurgia, Disciplina Cirurgia Cabeca & Pescoco, R Tessalia Vieira Camargo 126, BR-13083887 Campinas, SP, BrazilUniv Fortaleza Unifor, Med Sch, Av Washington Soares 1321, BR-60811905 Fortaleza, CE, BrazilUniv Fed Sao Paulo UNIFESP, Postgrad Program Biotechnol, Pedro Toledo 669, BR-04039903 Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Postgrad Programs Biotechnol & Struct & Funct Bio, Dept Ciencias Biol, Thyroid Mol Sci Lab,UNIFESP, Pedro Toledo 669, BR-04039903 Sao Paulo, SP, BrazilHosp Sirio Libanes, Mol Oncol Ctr, Rua Prof Daher Cutait 69, BR-01308060 Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Postgrad Program Biotechnol, Pedro Toledo 669, BR-04039903 Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Postgrad Programs Biotechnol & Struct & Funct Bio, Dept Ciencias Biol, Thyroid Mol Sci Lab,UNIFESP, Pedro Toledo 669, BR-04039903 Sao Paulo, SP, BrazilFAPESP [2009/53840-0]FAPESP[2010/12005-9, 2014/24549-4]Web of Scienc

Characterization of Dengue Virus Type 2: New Insights on the 2010 Brazilian Epidemic

Dengue viruses (DENV) serotypes 1, 2, and 3 have been causing yearly outbreaks in Brazil. In this study, we report the re-introduction of DENV2 in the coast of São Paulo State. Partial envelope viral genes were sequenced from eighteen patients with dengue fever during the 2010 epidemic. Phylogenetic analysis showed this strain belongs to the American/Asian genotype and was closely related to the virus that circulated in Rio de Janeiro in 2007 and 2008. The phylogeny also showed no clustering by clinical presentation, suggesting that the disease severity could not be explained by distinct variants or genotypes. The time of the most recent common ancestor of American/Asian genotype and the São Paulo and Rio de Janeiro (SP/RJ) monophyletic cluster was estimated to be around 40 and 10 years, respectively. Since this virus was first identified in Brazil in 2007, we suggest that it was already circulating in the country before causing the first documented outbreak. This is the first description of the 2010 outbreak in the State of São Paulo, Brazil, and should contribute to efforts to control and monitor the spread of DENVs in endemic areas

ATLANTIC ‐ PRIMATES : a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co‐occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

Genotype and phenotype landscape of MEN2 in 554 medullary thyroid cancer patients: the BrasMEN study

Multiple endocrine neoplasia type 2 (MEN2) is an autosomal dominant genetic disease caused by RET gene germline mutations that is characterized by medullary thyroid carcinoma (MTC) associated with other endocrine tumors. Several reports have demonstrated that the RET mutation profile may vary according to the geographical area. In this study, we collected clinical and molecular data from 554 patients with surgically confirmed MTC from 176 families with MEN2 in 18 different Brazili an centers to compare the type and prevalence of RET mutations with those from other countries. The most frequent mutations, classified by the number of families affected, occur in codon 634, exon 11 (76 families), followed by codon 918, exon 16 (34 families: 26 with M918T and 8 with M918V) and codon 804, exon 14 (22 families: 15 with V804M and 7 with V804L). When compared with other major published series from Europe, there are several similarities and some differences. While the mutations in codons C618, C620, C630, E768 and S891 present a similar prevalence, some mutations have a lower prevalence in Brazil, and others are found mainly in Brazil (G533C and M918V). These results reflect the singular proportion of European, Amerindian and African ancestries in the Brazilian mosaic genome83289298CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DO RIO GRANDE DO SUL - FAPERGSSem informaçãoSem informação2006/60402-1; 2010/51547-1; 2013/01476-9; 2014/06570-6; 2009/50575-4; 2010/51546-5; 2012/21942-116/2551-0000482-

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
