Purpose of the studyThis study intends to characterize a Portuguese patient population with chronic HCV and HIV coinfection, followed at our Research Unit, underline the importance of early treatment and incorporate the importance of DDA for retreatment of HCV infection.MethodsRetrospective, observational analysis of medical records of 348 HCV/HIV coinfected patients from 2001 to 2011. Demographic, epidemiological, clinical and laboratory data and virologic response were collected.Summary of resultsReview of 348 HCV/HIV coinfected patients, 121 of those (34.7%) under treatment, predominantly male (77.0%) and Caucasians (94.8%) with a median age of 44 yrs old (min 25; max 77 yrs). Intravenous drug use was the main route of HCV infection, in 71.3% of patients, and 8.3% were related with MSM. Frequent morbidities were alcohol abuse (46.8%), illicit drug use (70.1%), methadone (25.6%) and mental disturbances (12.3%) of patients. Regarding HIV infection, six were HIV‐2 and 342 HIV‐1; 36.1% were stage A and 29.6% were stage C (CDC Atlanta), 94.8% on antiretroviral treatment and only 21.9% of them with more than 350 TCD4 cell count. Genotype 1 was the most prevalent (58.1%–117 genotype 1a, 26 genotype 1b); 1.6% were genotype 2, 22.8% genotype 3 and 17.5% genotype 4. Previous to treatment initiation, HCV ARN was above 600.000 IU/mL in 56.9% patients. Fibrosis was evaluated by fibroelastography in 41.1% and hepatic biopsy in 26.3% of patients; in those, 44.0% had a score above F2 (METAVIR) and ALT was elevated 2 times the limit in 38.0%, with an average value of 94 UI/L. IL 28B testing was performed in only 35 patients at the time, with 45.7% CC and 17.1% CT genotype. Treatment was started in 34.8% of patients, with 1.7 treatments per individual, and regimen was based on peguilated interferon with ribavirin in 93.6% of cases (72.1% with peginterferon alfa 2a). The SVR rate was 51.2%, with 28.9% non responders, 3 relapsers and 9 treatment interruptions due to major toxicities.ConclusionsOur data presents a low HCV treatment initiation, illustrated by 65.2% patients who did not begin any treatment. The majority completed treatment and the SVR rate was similar to literature. Individualized approach is essential to determine the optimal time to initiate HCV treatment, to assess patient adherence and adverse events management, in order to optimize treatment and reserve DDA drugs to experienced patients with worse predictive factors.

The association between nutritional status and gait speed remains unclear. This study described gait speed in older adults and quantified the association between overweight, obesity, undernutrition risk and gait speed. Gait speed as potential indicator of nutritional outcomes was also explored. A cross-sectional analysis was conducted in a population-based sample of 1,500 older adults ≥65 years old. Compared to "normal body mass index" women, odds ratio for a slow gait speed was approximately 2-fold higher in"overweight", 4-fold higher in "obese" and 6-fold higher in women at "undernutrition risk". "Undernutrition risk" category resulted from joining "undernutrition risk/undernutrition". For men, these associations were in the same direction, but the odds ratio estimates halved. In women, identified gait speed cut-offs were 0.87 m/s for "obesity" and 0.79 m/s for "undernutrition risk". In men, 0.94 m/s is the cut-off in which most older adults were correctly classified relative to "undernutrition risk". About half of Portuguese older adults presented a gait speed ≤0.8 m/s. Overweight, obesity and undernutrition risk were directly and increasingly associated with slow gait speed, but approximately twice as high in women compared to men. Gait speed revealed potential utility in marking nutritional problems, but further investigation is recommended. ; The present project was 85% funded by the Public Health Initiatives Programme (PT06), financed by European Economic Area (EEA) Grants Financial Mechanism 2009 2014.

The compression process in the α-phase of europium trimolybdate was revised employing several experimental techniques. X-ray diffraction (using synchrotron and laboratory radiation sources), Raman scattering and photoluminescence experiments were performed up to a maximum pressure of 21 GPa. In addition, the crystal structure and Raman mode frequencies have been studied by means of first-principles density functional based methods. Results suggest that the compression process of α-Eu2(MoO4)3 can be described by three stages. Below 8 GPa, the α-phase suffers an isotropic contraction of the crystal structure. Between 8 and 12 GPa, the compound undergoes an anisotropic compression due to distortion and rotation of the MoO4 tetrahedra. At pressures above 12 GPa, the amorphization process starts without any previous occurrence of a crystalline-crystalline phase transition in the whole range of pressure. This behavior clearly differs from the process of compression and amorphization in trimolybdates with β′-phase and tritungstates with α-phase. ; We thank Diamond Light Source for access to beamline I15 (EE1746) that contributed to the results presented here.
