The manifestation of cholelithiasis after bariatric surgery may depend on genetic factors related to lipid metabolism, including apolipoprotein E (APOE) and cholesteryl ester transfer protein (CETP) gene polymorphisms.We investigated the association between APOE HhaI and CETP TaqIB polymorphisms [PCR-RFLP] and occurrence of cholelithiasis over up to 8 months of follow-up after gastroplasty to Roux-en-Y gastric bypass in 220 patients distributed in Group 1 (G1) 114 with cholelithiasis postoperatively and Group 2 (G2) 106 without cholelithiasis, including biochemical and anthropometric profiles analyses.In our series, the allelic and genotypic distributions of CETP TaqIB and APOE HhaI polymorphisms were similar in both groups (P 0.05). The subgroup analysis evidenced that 54% of the patients from G1, APOE*4 allele carriers compared with APOE*3/3 carriers, presented altered low-density lipoprotein cholesterol (LDL cholesterol) serum levels (P = 0.022) before bariatric surgery. The B1 allele for CETP was associated to more quickly elevation of HDL cholesterol levels just in individuals without cholelitiasis (P 0.0001). The multivariate logistic regression analysis demonstrates correlation between APOE*4 allele, higher total cholesterol (TC) serum levels and prediposition to cholelitiasis in preoperative period. However, the presence of postoperative cholelithiasis was not associated with altered lipid profile.The CETP TaqIB and APOE HhaI polymorphisms do not seem to have association with gallstones in the late postoperative bariatric surgery, considering that these genetic variants do not differ subgroups of patients who are eligible to routine prophylactic cholecystectomy, at least in Brazilian population.

Resistência insulínica consiste em reduzida resposta celular a esse hormônio e, portanto, disfunção do transporte de glicose para o meio intracelular. Esse fenômeno associa-se a fatores genéticos e principalmente comportamentais relacionados a obesidade e comorbidades a ela associadas como diabetes melito tipo 2, hipertensão arterial e dislipidemia. Entretanto, fatores clínicos de resistência insulínica também estão presentes em diabéticos tipo 1 não obesos na conhecida síndrome de extrema resistência à insulina subcutânea e intramuscular (DRIASM). Condição rara que consiste em resistência à ação da insulina no tecido subcutâneo e muscular e sensibilidade normal, ou próxima do normal, quando administrada via intravenosa. Tratamentos propostos até o momento mostram-se pouco efetivos e se relacionam a complicações e falhas frequentes. Descrevemos dois casos de pacientes femininas de 45 e 46 anos com DRIASM que se diferenciam dos demais já descritos por apresentar diagnóstico de diabetes melito tipo 1 tardio, hiperglicemia constante associada a complicações catabólicas, microvasculares (retinopatia) e neuropáticas sem, no entanto, nenhum episódio de cetoacidose diabética. Os tratamentos propostos variaram desde aplicação de insulina intramuscular e intravenosa até listagem para possível realização de transplante de pâncreas como tentativa de tratamento definitivo. Este trabalho teve aprovação do Comitê de Ética em Pesquisa da Faculdade de Medicina de São José do Rio Preto.

We evaluated genetic variants of apolipoprotein E (APOE HhaI) and their association with serum lipids in colorectal cancer (CRC), together with eating habits and personal history. Eight-seven adults with CRC and 73 controls were studied. APOE*2 (rs7412) and APOE*4 (rs429358) were identified by polymerase chain reaction-restriction fragment length polymorphism. APOE gene polymorphisms were similar in both groups, but the epsilon4/epsilon4 genotype (6%) was present only in controls. The patients had reduced levels (mean +/- SD) of total cholesterol and low-density lipoprotein cholesterol fraction (180.4 +/- 49.5 and 116.1 +/- 43.1 mg/dL, respectively) compared to controls (204.2 +/- 55.6, P = 0.135 and 134.7 +/- 50.8 mg/dL; P = 0.330, respectively) indicating that they were not statistically significant after the Bonferroni correction. The APOE*4 allele was associated with lower levels of total cholesterol, low- and high-density lipoprotein cholesterol fraction and increased levels of very low-density lipoprotein cholesterol fraction and triglycerides only among patients (P = 0.014). There was a positive correlation between the altered lipid profile and increased body mass indexes in both groups (P0.010). Moreover, a higher rate of hypertension and overweight was observed in controls (P0.002). In conclusion, the presence of the epsilon4/epsilon4 genotype only in controls may be due to a protective effect against CRC. Lower lipid profile values among patients, even those on lipid-rich diets associated with the APOE*4 allele, suggest alterations in the lipid synthesis and metabolism pathways in CRC.

The influence of medical students' knowledge concerning end-of-life care, considering ethical theories and clinical practice, remains controversial. We aimed to investigate medical students' knowledge of bioethical concepts related to moral kinds of death (euthanasia, disthanasia, and orthothanasia) and to analyze the influence of their clinical experience on practicing such approaches in a tertiary hospital in the state of São Paulo, Brazil. We interviewed 180 medical students [distributed in Group 1 (G1) - first to third- year students, and Group 2 (G2) - fourth to sixth-year students] to evaluate the influence of the course on "medical ethics" on ethical theories and clinical practice, using a closed questionnaire. The course on "medical ethics" did not distinguish the groups (P=0.704) in relation to bioethical concepts. Neologisms such as "cacothanasia" and "idiothanasia" were incorrectly viewed as bioethical concepts by 28% of the interviewees. Moreover, 45.3% of the sample considered health care professionals incapable of managing terminally ill patients, especially G2 (29%) as compared to G1 (16.5%, P=0.031). The concept of euthanasia was accepted by 41% of sample, as compared to 98.2% for orthothanasia. Among medical students that accepted ways to abbreviate life (22.9%), 30.1% belonged to G1, and only 16.1% to G2 (P=0.049). These medical students were unfamiliar with common bioethical concepts. Moreover, they considered healthcare professionals incapable of managing terminally ill patients. The ethical ideal of the "good death" reflects better acceptance of orthothanasia by medical students, suggesting a tendency to apply it in their future clinical practice. A influência do conhecimento de estudantes de medicina sobre o manejo com o fim da vida, considerando teorias éticas e aplicabilidade clínica, permanece controversa. Objetivamos investigar o conhecimento de estudantes de medicina sobre conceitos bioéticos a respeito dos tipos morais de morte (Eutanásia, Distanásia e Ortotanásia) e analisar a influência de suas experiências clínicas para praticá-los, em um hospital terciário do estado de São Paulo, Brasil. Nós entrevistamos 180 estudantes de medicina [distribuídos em Grupo 1 (G1) - estudantes do primeiro ao terceiro ano de graduação em medicina e Grupo 2 (G2) - estudantes do quarto ao sexto ano] para avaliar a influência do "curso de ética médica" em teorias éticas e prática clínica, utilizando um questionário fechado. O "curso de ética médica" não diferiu os grupos (P=0.704) sobre os conceitos bioéticos. Neologismos como Cacotanásia e Idiotanásia foram erroneamente considerados como conceitos bioéticos por 28% dos indivíduos. Além disso, 45.3% da amostra consideraram os profissionais de saúde inaptos ao manejo de pacientes terminais, principalmente G2 (29%) comparado a G1 (16.5%, P=0.031). O conceito de Eutanásia foi aceito por 41% da amostra, enquanto Ortotanásia por 98.2%. Dentre os estudantes de medicina que aceitaram maneiras para abreviar a vida (22.9%), 30.1% deles pertenciam a G1 enquanto somente 16.1% a G2 (P=0.049). Estudantes de medicina mostram desconhecimento sobre conceitos clássicos em Bioética. Além disso, consideram os profissionais de saúde inaptos ao manejo de pacientes terminais. O ideal ético considerando a "boa morte" reflete melhor aceitação dos estudantes de medicina pela Ortotanásia, sugerindo tendência em aplicá-la em sua futura prática clínica.

Insulin resistance signs reduced cellular response to this hormone and dysfunction of glucose transport to intracellular compartment. This phenomenon is associated to genetic factors and principally behavior factors correlating to obesity and its comorbidities, as type 2 diabetes mellitus, hypertension and dyslipidemia. However clinical factors of insulin resistance are still present at not obese type 1 diabetes in a known syndrome called type 1 diabetes mellitus with resistance to insulin administered subcutaneously and intramuscularly (DRIASM). This is a rare condition that consists into insulin resistance at subcutaneously and intramuscularly use and normal or near to normal sensitivity at intravenously way. Treatments until now proposed are ineffective and are related to frequent fails and complications. We report here two cases of DRIASM in 45 and 46 female patients that are different from others yet related because they have late diabetes type 1, sustained hyperglycemia associated to catabolic, microangiopathy and neuropathic complications without any ketoacidosis episode. The treatment vary from alternative ways for insulin infusion to inscription to a possible performance of pancreas transplantation like a experiment of definitive treatment.

To analyze the biochemical profile and to characterize metabolic syndrome (MS) in patients with cardiologic medical assistance using NCEP-ATPIII and IDF definitions.Two hundred patients and 140 controls were studied, considering total cholesterol (TC), HDL-cholesterol (HDLc), LDL-cholesterol (LDLc), VLDL-cholesterol (VLDLc), triglycerides (TG), fasting glycemia, abdominal waist and hypertension. Significance level was defined as P0.05.Patients showed increased glycemia levels (103+/-31.4 mg/dL) and reduced HDLc levels (48+/-13.4 mg/dL) when compared to controls (88+/-29.7 mg/dL, P0.0001 and 53+/-15.9 mg/dL, P=0.0075; respectively). Male controls 31-50 years old showed increased TC levels (215+/-40.4 mg/dL), LDL-cholesterol (134+/-34 mg/dL), VLDL-cholesterol (30+/-11.8 mg/dL) and TG (150+/-59.4 mg/dL) when compared to women (185+/-38.2 mg/dL, P=0.0137; 111+/-35.8 mg/dL; P=0.0324; 19+/-9.7 mg/dL; P=0.0009; 93+/-49 mg/dL, P=0.0010; respectively). Women over 50 years of age showed increased TC concentrations (216+/-35.9 mg/dL), HDL-cholesterol (54+/-12.8 mg/dL) and LDL-cholesterol (138+/-30.8 mg/dL) when compared to men (190+/-44.7 mg/dL, P=0.0103; 47+/-14.5 mg/dL, P=0.0229; 119+/-33.3 mg/dL; P=0.0176; respectively). NCEP-ATPIII and IDF definitions had characterized MS in 35.5% and 46% of patients, respectively, bolding glycemia, TG and hypertension.Elevated glycemia levels and reduced HDLc levels were detected in patients. Altered lipid profile observed in men 31-50 years old signals higher risk for cardiovascular diseases in young adults, while a similar profile in aged women can reflect hormonal physiological changes. Both definitions for MS diagnosis discriminate patients from controls, especially IDF, sometimes with lower capacity to determine high risk for cardiovascular complications. The high prevalence of MS in patients, even with cardiologic medical assistance, suggests predisposition for cardiovascular manifestations in Brazilian individuals.
