Efficacy and safety of travoprost 0.004%/timolol 0.5% fixed combination as transition therapy in patients previously on prostaglandin analog monotherapy

Purpose: To assess the safety and efficacy of transitioning patients whose intraocular pressure (IOP) had been insufficiently controlled on prostaglandin analog (PGA) monotherapy to treatment with travoprost 0.004%/timolol 0.5% fixed combination with benzalkonium chloride (TTFC). Methods: This prospective, multicenter, open-label, historical controlled, single-arm study transitioned patients who had primary open-angle glaucoma, pigment dispersion glaucoma, or ocular hypertension and who required further IOP reduction from PGA monotherapy to oncedaily treatment with TTFC for 12 weeks. IOP and safety (adverse events, corrected distance visual acuity, and slit-lamp biomicroscopy) were assessed at baseline, week 4, and week 12. A solicited ocular symptom survey was administered at baseline and at week 12. Patients and investigators reported their medication preference at week 12. Results: Of 65 patients enrolled, 43 had received prior travoprost therapy and 22 had received prior nontravoprost therapy (n = 18, bimatoprost; n = 4, latanoprost). In the total population, mean IOP was significantly reduced from baseline (P = 0.000009), showing a 16.8% reduction after 12 weeks of TTFC therapy. In the study subgroups, mean IOP was significantly reduced from baseline to week 12 (P = 0.0001) in the prior travoprost cohort (19.0% reduction) and in the prior nontravoprost cohort (13.1% reduction). Seven mild, ocular, treatment-related adverse events were reported. Of the ten ocular symptom questions, eight had numerically lower percentages with TTFC compared with prior PGA monotherapy and two had numerically higher percentages with TTFC (dry eye symptoms and ocular stinging/burning). At week 12, TTFC was preferred over prior therapy for 84.2% of patients (48 of 57) by the patients themselves, and for 94.7% of patients (54 of 57) by their physicians. Conclusion: When TTFC replaced PGA monotherapy in patients whose IOP had been uncontrolled, the outcome was a significant reduction in IOP and an acceptable safety and tolerability profile. Most patients and investigators preferred TTFC to prior PGA monotherapy. © 2012 Costa et al, publisher and licensee Dove Medical Press Ltd.

Synthesis, characterization and thermal study of solid mandelate of some bivalent transition metal ions in CO2 and N2 atmospheres

Solid state M-L, where M stands for bivalent transition metals (Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II)) and L is mandelate, were synthesized. Simultaneous thermogravimetry and differential scanning calorimetry, elemental analysis and complexometry were used to establish the stoichiometry and to study the thermal behaviour of these compounds in CO2 and N2 atmospheres. The results show that all the compounds were obtained in the anhydrous state and in agreement with the general formula ML2. The thermal decomposition of the compounds occurs in a single (Cu(II)), two (Ni(II)) three (Fe(II), Co(II)), four (Mn(II)) and five (Zn(II)) steps. The results also provided information concerning the ligand's denticity, thermal behaviour, final residues and identification of gaseous products evolved during the thermal decomposition of these compounds. © 2012 Akadémiai Kiadó, Budapest, Hungary.

Charge-ordering transition in (TMTTF)2X explored via dilatometry

Charge-ordering phenomena have been highly topical over the past few years. A phase transition towards a charge-ordered state has been observed experimentally in several classes of materials. Among them, many studies have been devoted to the family of quasi-one-dimensional organic charge-transfer salts (TMTTF)2X, where (TMTTF) stands for tetramethyltetrathiafulvalene and X for a monovalent anion (X = PF6, AsF6 and SbF6). However, the relationship between the electron localization phenomena and the role of the lattice distortion in stabilizing the charge-ordering pattern is poorly documented in the literature. Here we present a brief overview of selected literature results, with emphasis placed on recent thermal expansion experiments probing the charge-ordering transition of these salts. © 2013 IOP Publishing Ltd.

Edge effects and the impact of wildfires on populations of small non-volant mammals in the forest-savanna transition zone in Southern Amazonia

O efeito de borda e do fogo sobre a comunidade de pequenos mamíferos não-voadores foi investigada em uma área de transição entre Cerrado e Floresta em uma área de matriz de soja na Amazônia Oriental. Os indivíduos foram coletados em 24 transectos, dos quais 16 foram distribuídos em área sem efeito do fogo e oito distribuídos com efeito do fogo. Um total de 11 espécies foi registrado, incluindo seis roedores e cinco marsupiais. A espécie Hylaeamys megacephalus foi a mais abundante em áreas sem efeito do fogo. A abundância e riqueza de pequenos mamíferos não-voadores apresentaram uma diminuição em áreas queimadas, entretanto o efeito do fogo parece mascarar o efeito de borda nestas mesmas áreas. Em relação ao efeito de borda, sem nenhum efeito de fogo, a relação entre a abundância de pequenos mamíferos não-voadores com a distância da borda foi positiva. A relação entre a diversidade de pequenos mamíferos e efeito de borda pode ser ligada à vegetação matriz e características ecológicas de cada espécie.

Double-lumen catheter in the right jugular vein induces two sub-endothelial abscesses in an unusual place, the transition between the superior vena cava and the right atrium: a case report

Endocarditis is a type of infection that is common in internal medicine wards and in haemodialysis clinics. The location that is most affected are the heart valves. Herein, we report a case of an uncommon abscess, a sub-endothelial abscess between the transition of the superior vena cava and the right atrium. There were several emboli to the lung and foot, and the agent was related to Staphylococcus aureus and a double-lumen catheter. Usually, this type of abscess is located in valves, either the tricuspid valve if related to catheters or injection drug use or the mitral valve if related to other causes. An exhaustive review was made, but we found no information about the location of this abscess and the rarity of the event motivating the report of infection.

Thermal study in solid state of Zn(II)-diclofenac complex: Behavior kinetic of dehydration, transition phase and thermal decomposition

The dehydration, thermal decomposition and transition phase stage of Zn(II)-diclofenac compoundwere studied by simultaneous TG-DTA and DSC techniques. The TG and DSC curves of this compoundwere obtained with the mass of sample of 2 and 5 mg. Additionally, DSC curves were carried out inopened and closed a-alumina pans under static and nitrogen atmosphere. The DTA and DSC curves showthat this compound possesses exothermic transition phase between 170-180 ºC, which it is irreversible(monotropic reaction). The kinetics study of this transition phase stage was evaluated by DSC undernon-isothermal conditions. The obtained data were evaluated with the isoconversional method, where thevalues of activation energy (Ea/kJmol-1) was plotted in function of the conversion degree (a). The resultsshow that due to mass sample, different activation energies were obtained. From these curves a tendencycan be seen where the plots maintain the same profile for closed lids and almost run parallel to each other.
