ABSTRACT Alcohol consumption has long been considered a trigger for recurrent gout attacks; however, this hypothesis has not been formally tested.
We conducted an Internet-based case-crossover study to assess several putative risk factors, including alcohol consumption, thought to trigger recurrent gout attacks. Subjects who had an attack within the past year were recruited online and asked to provide access to medical records pertaining to their gout. Data were obtained on the amount and type of alcoholic beverage consumed on each day over the 2-day period before a gout attack and on each day over a 2-day period during the intercritical period. We examined the amount and type of alcohol consumption and the risk of recurrent gout attacks using a conditional logistic regression adjusting for diuretic use and purine intake.
A total of 197 subjects were recruited online over a 10-month period. Of those, 179 (91%) fulfilled the American College of Rheumatology Criteria for gout. Compared with no alcohol consumption, odds ratios for recurrent gout attacks were 1.1, 0.9, 2.0, and 2.5 for 1 to 2, 3 to 4, 5 to 6, and 7 or more drinks consumed over the 2-day period, respectively (P<.005). A dose-response relationship of risk of gout attacks was more evident for alcohol consumed over the last 24 hours. An increased risk of recurrent gout attacks was found for each type of beverage consumed.
Alcohol consumption triggers recurrent gout attacks. This effect was likely to occur within 24 hours after its consumption.

    ABSTRACT: La gota es una patología ampliamente descrita a lo largo de la evolución de la historia de la medicina. Desde los tiempos de Galeno hasta nuestros días, continúa siendo un problema de salud pública que genera morbilidad e incapacidad en quien la padece. Aunque la terapéutica no ha cambiado mucho en los últimos años, se hace necesaria una actualización de la información existente en la literatura, ya que se siguen presentando errores en su manejo, no solo en cuanto a la indicación de un medicamento en una situación clínica específica, sino también en el cuidado atento que amerita el posible desarrollo de efectos secundarios a los fármacos tradicionalmente empleados para su manejo.

    ABSTRACT: Treatment of gouty inflammation, hyperuricemia, and comorbidities are distinct but closely linked core elements of therapeutic strategy for patients with gout. All gout patients should be evaluated and treated for comorbid medical problems such as hypertension, metabolic syndrome, and coronary artery disease. Lifestyle modifications, including weight loss, are important adjuncts to pharmacologic urate lowering. The target serum urate level for urate-lowering therapy in most patients is less than 6.0 mg/dL. Serial monitoring of serum uric acid levels is essential, following the initiation of urate-lowering therapy. High-dose oral colchicine for the treatment of acute gout has an unacceptable risk:benefit ratio. Maintenance colchicine should be continued for at least the first 6 months of urate-lowering therapy. Allopurinol should not be initiated or discontinued during an acute gout flare. In most cases, allopurinol and other urate-lowering therapies should be continued for life.

    ABSTRACT: High-speed assembly makes strict demands on path and trajectory planning systems. In such systems the stages of path planning, trajectory planning, and 'low-level' control are normally separated, which admits functional simplicity but may not produce the most useful trajectories. Our active motion planner merges these levels by building a low-level controller into a potential-field planning loop. The input to the planner is a coarse set of via-points; the planner incorporates a goal that moves between these via-points, as in our previous work. The active motion planner produces relatively smooth paths; furthermore, by adjusting the relative gains of the active force (i.e., internal controller) and potential field terms the planner is able to avoid many of the local minima traps that bedevil potential field techniques. The combined planner is illustrated using a (simulated) PUMA robot arm.
