RESUMO
Among non-covalent interactions, halogen bonding is emerging as a new powerful tool for supramolecular self-assembly. Here, along with a green and effective method, we report three new halogen-bonded cocrystals containing uracil derivatives and 1,2,4,5-tetrafluoro-3,6-diiodobenzene as X-bond donor coformer. These multicomponent solids were prepared both by solvent-drop grinding and solution methods and further characterized by powder and single-crystal X-ray diffraction, Fourier-transformed infrared spectroscopy, and thermal methods (TGA-DSC). In order to study the relative importance of hydrogen versus halogen bonds in the crystal packing, computational methods were applied.

Plasmonic nanoparticles, especially gold ones, have been widely employed as photosensitizers in photoelectrovoltaic or photocatalytic systems. To improve the system's performance, a greater interaction of the nanoparticles with the semiconductor, generally TiO2, is desired. Moreover, this performance is enhanced when an efficient covering of TiO2 surface by the sensitizer is achieved. The Brust-Schiffrin-like methods are of the most employed approaches for nanoparticles synthesis. In a traditional approach, the reduction of the gold precursor is performed in the presence of a stabilizer (typically a thiol molecule) free in solution. A second step in which the obtained nanoparticles are anchored to the semiconductor surface is necessary in the case of photosensitive applications. Drawbacks like steric hindrance turn more difficult the covering of the semiconductor's surface by nanoparticles. In this paper, we report a variation of this methodology, where the linker is previously anchored to the TiO2 nanoparticles surface. The resulting system is employed as the stabilizer in the gold reduction step. This strategy is carried out in aqueous media in two simple steps. A great covering of the titania surface by gold nanoparticles is achieved in all cases and the gold nanoparticles in the resulting nanoaggregate might be useful for photoelectrovoltaic or photocatalytic applications.
RESUMO
We analyze an AC-driven dimer chain connected to a strongly biased electron source and drain. It turns out that the resulting transport exhibits fingerprints of topology. They are particularly visible in the driving-induced current suppression and the Fano factor. Thus, shot noise measurements provide a topological phase diagram as a function of the driving parameters. The observed phenomena can be explained physically by a mapping to an effective time-independent Hamiltonian and the emergence of edge states. Moreover, by considering quantum dissipation, we determine the requirements for the coherence properties in a possible experimental realization. For the computation of the zero-frequency noise, we develop an efficient method based on matrix-continued fractions.
RESUMO
The application of halogen bonding in pharmaceutical chemistry remains a challenge. In this work, novel halogen-bonded cocrystals based on azole antifungal active pharmaceutical ingredients (APIs) and the ditopic molecule 1,4-diiodotetrafluorobenzene are reported. Their crystal structural features, spectroscopic properties, and thermal stability were studied. The components are bound through I···N from the triazole moieties present in all of the compounds. The molecular electrostatic potential (MEP) surfaces and quantum theory of atoms in molecules (QTAIM) calculations are used to rationalize the presence of hydrogen and halogen bonds in the resulting structures and their energetic analysis. The relative halogen bond ability of the different groups of voriconazole, fluconazole, and itraconazole was analyzed using MEP surfaces, demonstrating this approach to be an interesting tool to predict halogen-bonding preferences.
RESUMO
OBJECTIVES: Voice care services aim to provide effective and meaningful voice care. Current practice guidance recommends a multidisciplinary voice care approach, supported by the evidence-base and practitioner experience. However, unlike other areas of physical and mental health, current voice care guidance does not explicitly include the voices of experts-by-experience, meaning those who have lived experience of voice difficulties. The perspectives of those working within nonclinical voice professions, such as vocal coaches, are also often omitted. There is therefore a need for updated practice guidance which prioritizes expert-by-experience and nonclinical perspectives. METHODS: Vocal Health Education hosted a consensus meeting in London, UK. The meeting was coproduced with experts-by-experience, and attendees included those with lived experience of voice difficulties and practitioners across a range of disciplines within voice care. The content of the meeting was synthesized into themes and associated recommendations were drafted and agreed to by all attendees. RESULTS: The consensus statement offers practical advice to those working in voice care. Recommendations are offered for multidisciplinary and biopsychosocial voice care, with a focus on person-centered practice and the valuing of lived experience. Through discussion, consensus was reached regarding recommendations for voice care assessment and treatment, practitioner approach, psychosocial considerations, and service design. The need for greater expert-by-experience involvement, coproduction, and co-construction was emphasized throughout. CONCLUSIONS: This report emphasizes the voices of those with lived experience. It highlights ways of updating or improving current care, with the aim of informing clinical practice as well as research and service development. The consensus statement is the first in voice care to include experts-by-experience at the center of its recommendations, underlining the need for more coproduced and co-constructed research and practice within voice healthcare.
RESUMO
OBJECTIVES: To study baseline factors associated with hypo- and hypernatremia in older patients attended in emergency departments (EDs) and explore the association between these dysnatremias and indicators of severity in an emergency. MATERIAL AND METHODS: We included patients attended in 52 Spanish hospital EDs aged 65 years or older during a designated week. All included patients had to have a plasma sodium concentration on record. Patients were distributed in 3 groups according to sodium levels: normal, 135-145 mmol/L; hyponatremia, 135 mmol/L; or hypernatremia > 145 mmol/L. We analyzed associations between sodium concentration and 24 variables (sociodemographic information, measures of comorbidity and baseline functional status, and ongoing treatment for hypo- or hypernatremia). Indicators of the severity in emergencies were need for hospitalization, in-hospital mortality, prolonged ED stay (> 12 hours) in discharged patients, and prolonged hospital stay (> 7 days) in admitted patients. We used restricted cubic spline curves to analyze the associations between sodium concentration and severity indicators, using 140 mmol/L as the reference. RESULTS: A total of 13 368 patients were included. Hyponatremia was diagnosed in 13.5% and hypernatremia in 2.9%. Hyponatremia was associated with age ($ 80 years), hypertension, diabetes mellitus, an active neoplasm, chronic liver disease, dementia, chemotherapy, and needing help to walk. Hypernatremia was associated with needing help to walk and dementia. The percentages of cases with severity indicators were as follows: hospital admission, 40.8%; in-hospital mortality, 4.3%; prolonged ED stay, 15.9%; and prolonged hospital stay, 49.8%. Odds ratios revealed associations between lower sodium concentration cut points in patients with hyponatremia and increasing need for hospitalization (130 mmol/L, 2.24 [IC 95%, 2.00-2.52]; 120 mmol/L, 4.13 [3.08-5.56]; and 110 mmol/L, 7.61 [4.53-12.8]); risk for in-hospital death (130 mmol/L, 3.07 [2.40-3.92]; 120 mmol/L, 6.34 [4.22- 9.53]; and 110 mmol/L, 13.1 [6.53-26.3]); and risk for prolonged ED stay (130 mmol/L, 1.59 [1.30-1.95]; 120 mmol/L, 2.77 [1.69-4.56]; and 110 mmol/L, 4.83 [2.03-11.5]). Higher sodium levels in patients with hypernatremia were associated with increasing need for hospitalization (150 mmol/L, 1.94 [1.61-2.34]; 160 mmol/L, 4.45 [2.88-6.87]; 170 mmol/L, 10.2 [5.1-20.3]; and 180 mmol/L, 23.3 [9.03-60.3]); risk for in-hospital death (150 mmol/L, 2.77 [2.16-3.55]; 160 mmol/L, 6.33 [4.11-9.75]; 170 mmol/L, 14.5 [7.45-28.1]; and 180 mmol/L, 33.1 [13.3-82.3]); and risk for prolonged ED stay (150 mmol/L, 2.03 [1.48-2.79]; 160 mmol/L, 4.23 [2.03-8.84]; 170 mmol/L, 8.83 [2.74-28.4]; and 180 mmol/L, 18.4 [3.69-91.7]). We found no association between either type of dysnatremia and prolonged hospital stay. CONCLUSION: Measurement of sodium plasma concentration in older patients in the ED can identify hypo- and hypernatremia, which are associated with higher risk for hospitalization, death, and prolonged ED stays regardless of the condition that gave rise to the dysnatremia.
OBJETIVO: Estudiar los factores basales asociados a hiponatremia e hipernatremia en pacientes mayores atendidos en urgencias y la relación de estas disnatremias con eventos indicadores de gravedad. METODO: Se incluyeron durante una semana a todos los pacientes atendidos en 52 servicios de urgencias hospitalarios españoles de edad $ 65 años con determinación de sodio plasmático. Se formaron tres grupos: sodio normal (135-145 mmol/L), hiponatremia ( 135 mmol/L) e hipernatremia (> 145 mmol/L). Se investigó la relación de 24 factores sociodemográficos, de comorbilidad, estado funcional basal y tratamiento crónico con hipo e hipernatremia. Como eventos de gravedad se recogieron necesidad de hospitalización, mortalidad intrahospitalaria, estancia prolongada en urgencias (> 12 horas) en dados de alta y hospitalización prolongada (> 7 días) en hospitalizados, y se analizó su relación con la concentración de sodio mediante curvas spline cúbicas restringidas ajustadas, tomando el valor 140 mmol/L como referencia. RESULTADOS: Se incluyeron 13.368 pacientes (13,5% hiponatremia, 2,9% hipernatremia). La hiponatremia se asoció a edad $ 80 años, hipertensión arterial, diabetes mellitus, neoplasia activa, hepatopatía crónica, demencia, tratamiento con quimioterápicos y ayuda para la deambulación, y la hipernatremia a dependencia, necesidad de ayuda para deambular y demencia. La hospitalización fue del 40,8%, la mortalidad intrahospitalaria del 4,3%, la estancia prolongada en urgencias del 15,9% y la hospitalización prolongada del 49,8%. A mayor hiponatremia, mayor necesidad de hospitalización (sodio 130 mmol/L: OR:2,24; IC 95%: 2,00-2,52; 120 mmol/L: 4,13, 3,08-5,56; 110 mmol/L: 7,61, 4,53-12,8), mortalidad intrahospitalaria (130 mmol/L: 3,07, 2,40-3,92; 120 mmol/L: 6,34, 4,22-9,53; 110 mmol/L: 13,1, 6,53-26,3) y estancia prolongada en urgencias (130 mmol/L: 1,59, 1,30-1,95; 120 mmol/L: 2,77, 1,69-4,56; 110 mmol/L: 4,83, 2,03-11,5), y a mayor hipernatremia mayor necesidad de hospitalización (150 mmol/L: 1,94, 1,61-2,34; 160 mmol/L: 4,45, 2,88-6,87; 170 mmol/L: 10,2, 5,1-20,3; 180 mmol/L: 23,3, 9,03-60,3), mortalidad intrahospitalaria (150 mmol/L: 2,77, 2,16-3,55; 160 mmol/L: 6,33, 4,11-9,75; 170 mmol/L: 14,5, 7,45-28,1; 180 mmol/L: 33,1, 13,3-82,3) y estancia prolongada en urgencias (150 mmol/L: 2,03, 1,48-2,79; 160 mmol/L: 4,23, 2,03-8,84; 170 mmol/L: 8,83, 2,74-28,4; 180 mmol/L: 18,4, 3,69-91,7). No hubo asociación entre estas disnatremias y hospitalización prolongada. CONCLUSIONES: El sodio plasmático determinado en urgencias en pacientes mayores permite identificar hiponatremias e hipernatremias, las cuales se asocian a un riesgo incrementado de hospitalización, mortalidad y estancia prolongada en urgencias independientemente de la causa que haya generado la disnatremia.

OBJECTIVES: The aims of this study in the Emergency Department and Elder Needs (EDEN) series were to explore associations between clinical variables on arrival at the ED (baseline) and the insertion of a bladder catheter, and the relation between catheterization and deterioration to a more complex or serious clinical state. MATERIAL AND METHODS: Included were all patients aged 65 years or older attended during 1 week in 52 Spanish EDs. Patients were grouped according to whether a bladder catheter was or was not inserted in the ED. We used multivariable logistical regression to explore associations between catheterization and patient age, sex, 10 comorbidities, 7 baseline status variables, and 6 clinical variables. Progression was considered serious or complex if the patient died or required hospitalization, a prolonged hospital stay, or discharge to a care facility. We also explored the association between age and catheterization using adjusted restricted cubic spline (RCS) curves with a cutoff value of 65 years. RESULTS: Participating hospitals enrolled 24 573 patients; bladder catheters were inserted in 976 (4%). Of these, 44.3% were discharged from the ED. Fifteen of the 24 variables were independently associated with bladder catheterization. Factors with the strongest associations according to odds ratios (ORs) were impaired consciousness (OR, 2.50; 95% CI, 1.90-3.30), dehydration (OR, 2.24; 95% CI, 1.85-2.72), and male sex (OR, 2.12; 95% CI, 1.84- 2.44). Age 80 years or older was also associated with bladder catheterization (OR, 1.17; 95% CI, 1.01-1.358). The adjusted RCS curves showed a progressive linear increase in the probability of catheterization with age. The increase was constant in men and stabilized after the age of 85 years in women (P-interaction .001). Bladder catheterization was associated with hospitalization (OR, 2.31; 95% CI, 1.99-2.68), intensive care unit admission (OR, 4.64; 95% CI, 3.04-7.09), prolonged stay in the ED for discharged patients (OR, 2.28; 95% CI, 1.75-2.96), in-hospital death (OR, 1.99; 95% CI, 1.54-2.57), and 30-day death (OR, 1.66; 95% CI, 1.33-2.08). No associations were found between catheterization and prolonged hospital stay (OR, 1.11; 95% CI, 0.92-1.34) or need for a care facility on discharge (OR, 1.50; 95% CI, 0.98-2.29). CONCLUSION: Certain patient characteristics and baseline clinical conditions are associated with bladder catheterization in patients of advanced age. The main factors were decreased consciousness, dehydration, and male sex. Even after adjustment for related factors, catheterization is independently associated with progression to more complex or serious clinical states.
OBJETIVO: Estudiar las variables de estado basal y de situación clínica a la llegada a urgencias relacionadas con la práctica de sondaje vesical (SV) en pacientes mayores, y si el SV está asociado a una evolución más compleja o grave. METODO: Se incluyeron todos los pacientes de edad 65 años atendidos durante una semana en 52 servicios de urgencias (SU) españoles, que fueron clasificados en función de si se practicó o no SV en el SU. Se investigó la relación de SV con edad, sexo, 10 variables de comorbilidad, 7 de estado basal y 6 de situación clínica mediante un modelo de regresión logística multivariable. Se consideró la evolución como grave o compleja si existió necesidad de hospitalización, estancia prolongada, necesidad de residencia al alta o muerte. La relación entre edad y SV se exploró también mediante curvas spline cúbicas restringidas (SCR) ajustadas, tomando la edad de 65 años como referencia. RESULTADOS: Se incluyeron 24.573 pacientes, de los que 976 (4%) recibieron SV. De éstos, el 44,3% fueron dados de alta desde urgencias. De las 25 variables exploradas, 15 se relacionaron independientemente con el SV, y las más manifiestas fueron disminución de consciencia (OR = 2,50, IC 95% = 1,90-3,30), deshidratación (OR = 2,24, IC 95% = 1,85-2,72) y sexo masculino (OR = 2,12, IC 95% = 1,84-2,44). La edad 80 años también se asoció a SV (OR = 1,17, IC 95% = 1,01-1,358), y las curvas SCR ajustadas mostraron un incremento progresivo y lineal de la probabilidad de SV con la edad, constante en hombres y que se estabilizaba a partir de los 85 años en mujeres (p interacción 0,001). El SV se asoció a necesidad de hospitalización (OR = 2,31, IC 95% = 1,99-2,68), hospitalización en intensivos (OR = 4,64, IC 95% = 3,04-7,09), estancia prolongada en urgencias en los pacientes dados de alta (OR = 2,28, IC 95% = 1,75-2,96) y mortalidad intrahospitalaria (OR = 1,99, IC 95% = 1,54-2,57) y a 30 días (OR=1,66, IC 95% = 1,33-2,08), pero no con hospitalización prolongada (OR = 1,11, IC 95% = 0,92-1,34) ni con necesidad de residencia al alta (OR = 1,50, IC 95% = 0,98-2,29). CONCLUSIONES: Determinadas características del paciente mayor y de su estado clínico se asocian con realizar un SV en urgencias, entre las que destacan la disminución de consciencia, la deshidratación y el sexo masculino. Aun teniendo en cuenta los factores asociados a SV en urgencias, este procedimiento se asocia independientemente con evoluciones más complejas o graves.

Lactose intolerance is a pathology caused by lactase enzyme deficiency, usually produced in the intestinal cells provoking symptoms as abdominal pain, bloating, diarrhea, gas and nausea. Gaxilose, 4-O-ß-D galactopyranosyl-d-xylose, is used as a diagnostic drug for a non-invasive method for hypolactasia diagnosis. To date, no definitive guide for identifying gaxilose and distinguishing between crystalline forms is available. Data have been collected from a number of different analytical techniques in order to provide a full characterization of the compound and a simple method to discriminate between two solid forms.

Alpha-synuclein (α-Syn) is a key protein involved in Parkinson's disease (PD) pathology. PD is characterized by the loss of dopaminergic neuronal cells in the substantia nigra pars compacta and the abnormal accumulation and aggregation of α-Syn in the form of Lewy bodies and Lewy neurites. More precisely, the aggregation of α-Syn is associated with the dysfunctionality and degeneration of neurons in PD. Moreover, mutations in the SNCA gene, which encodes α-Syn, cause familial forms of PD and are the basis of sporadic PD risk. Given the role of the α-Syn protein in the pathology of PD, animal models that reflect the dopaminergic neuronal loss and the widespread and progressive formation of α-Syn aggregates in different areas of the brain constitute a valuable tool. Indeed, animal models of PD are important for understanding the molecular mechanisms of the disease and might contribute to the development and validation of new therapies. In the absence of animal models that faithfully reproduce human PD, in recent years, numerous animal models of PD based on α-Syn have been generated. In this review, we summarize the main features of the α-Syn pre-formed fibrils (PFFs) model and recombinant adeno-associated virus vector (rAAV) mediated α-Syn overexpression models, providing a detailed comparative analysis of both models. Here, we discuss how each model has contributed to our understanding of PD pathology and the advantages and weakness of each of them. SIGNIFICANCE: Here, we show that injection of α-Syn PFFs and overexpression of α-Syn mediated by rAAV lead to a different pattern of PD pathology in rodents. First, α-Syn PFFs models trigger the Lewy body-like inclusions formation in brain regions directly interconnected with the injection site, suggesting that there is an inter-neuronal transmission of the α-Syn pathology. In contrast, rAAV-mediated α-Syn overexpression in the brain limits the α-Syn aggregates within the transduced neurons. Second, phosphorylated α-Syn inclusions obtained with rAAV are predominantly nuclear with a punctate appearance that becomes diffuse along the neuronal fibers, whereas α-Syn PFFs models lead to the formation of cytoplasmic aggregates of phosphorylated α-Syn reminiscent of Lewy bodies and Lewy neurites.

MOTIVATION: Systematic differences due to experimental features of microarray experiments are present in most large microarray data sets. Many different experimental features can cause biases including different sources of RNA, different production lots of microarrays or different microarray platforms. These systematic effects present a substantial hurdle to the analysis of microarray data. RESULTS: We present here a new method for the identification and adjustment of systematic biases that are present within microarray data sets. Our approach is based on modern statistical discrimination methods and is shown to be very effective in removing systematic biases present in a previously published breast tumor cDNA microarray data set. The new method of 'Distance Weighted Discrimination (DWD)' is shown to be better than Support Vector Machines and Singular Value Decomposition for the adjustment of systematic microarray effects. In addition, it is shown to be of general use as a tool for the discrimination of systematic problems present in microarray data sets, including the merging of two breast tumor data sets completed on different microarray platforms.
