Patients with AIDS-defining cancers are not universally screened for HIV: a 10-year retrospective analysis of HIV-testing practices in a Swiss university hospital.

OBJECTIVES: Kaposi's sarcoma (KS), invasive cervical carcinoma (ICC) and non-Hodgkin lymphoma (NHL) have been listed as AIDS-defining cancers (ADCs) by the Centers for Disease Control and Prevention since 1993. Despite this, HIV screening is not universally mentioned in ADC treatment guidelines. We examined screening practices at a tertiary centre serving a population where HIV seroprevalence is 0.4%. METHODS: Patients with KS, ICC, NHL and Hodgkin lymphoma (HL), treated at Lausanne University Hospital between January 2002 and July 2012, were studied retrospectively. HIV testing was considered part of the oncology work-up if performed between 90 days before and 90 days after the cancer diagnosis date. RESULTS: A total of 880 patients were examined: 10 with KS, 58 with ICC, 672 with NHL and 140 with HL. HIV testing rates were 100, 11, 60 and 59%, and HIV seroprevalence was 60, 1.7, 3.4 and 5%, respectively. Thirty-seven patients (4.2%) were HIV-positive, of whom eight (22%) were diagnosed at oncology work-up. All newly diagnosed patients had CD4 counts < 200 cells/μL and six (75%) had presented to a physician 12-236 weeks previously with conditions warranting HIV testing. CONCLUSIONS: In our institution, only patients with KS were universally screened. Screening rates for other cancers ranged from 11 to 60%. HIV seroprevalence was at least fourfold higher than the population average. As HIV-positive status impacts on cancer patient medical management, HIV screening should be included in oncology guidelines. Further, we recommend that opt-out screening should be adopted in all patients with ADCs and HL.

Efeito da formononetina (7 hidroxi, 4'metoxi isoflavona) na colonização micorrízica e crescimento do milho em solo contendo excesso de metais pesados

O excesso de metais pesados contamina o solo, exercendo impacto negativo sobre os microrganismos e ação tóxica sobre as plantas, dificultando a revegetação e reabilitação de áreas degradadas. No presente estudo, avaliou-se o efeito da aplicação do isoflavonóide formononetina (7 hidroxi, 4'metoxi isoflavona) no crescimento e absorção de metais pelo milho (Zea mayz L.) em mistura de solo com proporções crescentes de um solo contaminado que continha 16.904, 194, 219 e 836 mg dm-3 de solo de Zn, Cd, Pb e Cu, respectivamente. Esse solo foi diluído com solo não contaminado para obter misturas com 0; 2,5; 5,0; 7,5 e 10,0% p/p do solo contaminado. Nas misturas de solo, infestadas com propágulos de fungos micorrízicos, foi plantado milho, com e sem a aplicação de solução de formononetina sintética (5 mg L-1) equivalente a 400 µg kg-1 de solo. Verificou-se um efeito depressivo acentuado da elevação da contaminação do solo na colonização micorrízica e no crescimento das plantas. A formononetina estimulou a colonização nos níveis mais baixos de contaminação e exerceu efeito positivo no crescimento do milho. A absorção dos metais, em especial de Zn e Cd, aumentou com a elevação da contaminação, sendo os teores de Zn menores nas plantas com formononetina, enquanto os teores de Fe foram maiores nestas plantas até 7,5% de solo contaminado. Os resultados indicam que a formononetina reduz, de modo indireto, por meio da micorriza, os efeitos adversos do excesso de metais no solo, especialmente de Zn no milho. O favorecimento da formação de micorriza diminui a absorção de Zn e aumenta a de Fe, podendo ser este o mecanismo responsável pela ação amenizante da formononetina na toxidez de metais pesados no milho. Conclui-se que o uso da formononetina pode facilitar a revegetação de solos contaminados com metais pesados.

Fuel metabolism during exercise in euglycaemia and hyperglycaemia in patients with type 1 diabetes mellitus--a prospective single-blinded randomised crossover trial.

Aims/hypothesis We assessed systemic and local muscle fuel metabolism during aerobic exercise in patients with type I diabetes at euglycaemia and hyperglycaemia with identical insulin levels.Methods This was a single-blinded randomised crossover study at a university diabetes unit in Switzerland. We studied seven physically active men with type I diabetes (mean +/- SEM age 33.5 +/- 2.4 years, diabetes duration 20.1 +/- 3.6 years, HbA(1c) 6.7 +/- 0.2% and peak oxygen uptake [VO2peak] 50.3 +/- 4.5 ml min(-1) kg(-1)). Men were studied twice while cycling for 120 min at 55 to 60% of VO2peak, with a blood glucose level randomly set either at 5 or 11 mmol/l and identical insulinaemia. The participants were blinded to the glycaemic level; allocation concealment was by opaque, sealed envelopes. Magnetic resonance spectroscopy was used to quantify intramyocellular glycogen and lipids before and after exercise. Indirect calorimetry and measurement of stable isotopes and counter-regulatory hormones complemented the assessment of local and systemic fuel metabolism.Results The contribution of lipid oxidation to overall energy metabolism was higher in euglycaemia than in hyperglycaemia (49.4 +/- 4.8 vs 30.6 +/- 4.2%; p<0.05). Carbohydrate oxidation accounted for 48.2 +/- 4.7 and 66.6 +/- 4.2% of total energy expenditure in euglycaemia and hyperglycaemia, respectively (p<0.05). The level of intramyocellular glycogen before exercise was higher in hyperglycaemia than in euglycaemia (3.4 +/- 0.3 vs 2.7 +/- 0.2 arbitrary units [AU]; p<0.05). Absolute glycogen consumption tended to be higher in hyperglycaemia than in euglycaemia (1.3 +/- 0.3 vs 0.9 +/- 0.1 AU). Cortisol and growth hormone increased more strongly in euglycaemia than in hyperglycaemia (levels at the end of exercise 634 52 vs 501 +/- 32 nmol/l and 15.5 +/- 4.5 vs 7.4 +/- 2.0 ng/ml, respectively; p<0.05).Conclusions/interpretation Substrate oxidation in type I diabetic patients performing aerobic exercise in euglycaemia is similar to that in healthy individuals revealing a shift towards lipid oxidation during exercise. In hyperglycaemia fuel metabolism in these patients is dominated by carbohydrate oxidation. Intramyocellular glycogen was not spared in hyperglycaemia.
