    El objeto de la presente investigación documental es sobre el incremento de la mora en la empresa Grupo Comercial de Nicaragua S.A casa comercial ¨El Bodegón¨, sucursal Estelí durante el I semestre 2015. La empresa El Bodegón, sucursal Estelí, abrió sus operaciones en el año 2007, siendo una de las más recientes en esta ciudad. Es una empresa privada, comercializadora de electrodomésticos para el hogar, la industria y el comercio, ofreciendo al consumidor bienestar al satisfacer sus necesidades a través de un excelente servicio y facilidades de crédito. Es intermediaria entre productor y consumidor su función primordial es la compra-venta de electrodomésticos. El aumento de la mora crediticia es uno de los efectos indeseables de la crisis mundial, este indicador hace que las personas que tienen su crédito en dicha empresa tratan de mantener sus deudas al día para cuidar su record crediticio. Toda actividad empresarial se maneja bajo políticas o normas que orientan la diversidad de actividades comerciales que se dan en el mercado desde el punto de vista mercantil; por lo tanto considerando que el crédito es un proceso ordenado de pasos y procedimientos interconectados al desenvolvimiento económico y financiero necesita de políticas para que dicha actividad se encausen sobre objetivos específicos

    PurposeTo evaluate the prevalence of novel candidate Sjogren syndrome (SS) autoantibodies [salivary protein-1 (SP-1), parotid secretory protein, carbonic anhydrase 6] in the DRy Eye Assessment and Management (DREAM) cohort, a study evaluating the effectiveness of omega-3 fatty acid supplements for the treatment of dry eye.MethodsParticipants underwent ocular surface examinations and serological testing for traditional and novel SS autoantibodies. Dry eye assessment and management participants were categorized into the following 3 groups: 1) no history of SS or other autoimmune diseases and negative traditional SS autoantibodies (n = 352); 2) no history of SS but a history of other autoimmune diseases (n = 66); and 3) those who met the 2012 American College of Rheumatology SS classification criteria (n = 52).ResultsEleven percent had a history of SS, and 6% of those without a history of SS most likely had undiagnosed SS. The SS group had a higher prevalence of SP-1 autoantibodies than the group without SS or other autoimmune diseases (33% vs. 19%; P = 0.02) but had no difference in carbonic anhydrase 6 (P = 0.31) or parotid secretory protein autoantibodies (P = 0.33). Participants who were positive for the traditional autoantibodies alone or positive for both traditional and novel autoantibodies had the highest scores for corneal (P = 0.002) and conjunctival staining (P < 0.001).ConclusionsData from this multicenter, prospective study demonstrated that one of the novel candidate autoantibodies, SP-1, is associated with underlying SS and that novel autoantibodies may be associated with worse ocular surface disease. Future longitudinal studies are needed to evaluate their utility in screening patients with dry eye for SS

    A Wait-Free Deque With Polylogarithmic Step Complexity

    The amortized step complexity of operations on all previous lock-free implementations of double-ended queues is linear in the number of processes. This paper presents the first concurrent double-ended queue where the amortized step complexity of each operation is polylogarithmic. Since a stack is a special case of a double-ended queue, this is also the first concurrent stack with polylogarithmic step complexity. The implementation is wait-free and the amortized step complexity is O(log² p + log q) per operation, where p is the number of processes and q is the size of the double-ended queue

    SIGNIFICANCE:Identification of the association of specific signs of dry eye disease with specific visual function deficits may allow for more targeted approaches to treatment. PURPOSE:The purpose of this study was to explore the association of dry eye signs and symptoms with visual acuity (VA) and contrast sensitivity in the Dry Eye Assessment and Management study. METHODS:Baseline data from participants in the Dry Eye Assessment and Management study were used in this secondary cross-sectional analysis. Standardized procedures were used to obtain results on the Ocular Surface Disease Index (OSDI), high-contrast logMAR VA, contrast sensitivity, tear film debris, tear breakup time (TBUT), corneal fluorescein staining, meibomian gland evaluation, conjunctival lissamine green staining, and Schirmer test scores. Generalized linear models that included age, refractive error status, and cataract status were used to assess the association between VA and contrast sensitivity with OSDI score and each dry eye sign. The Hochberg procedure was used to account for multiple comparisons. RESULTS:Among 487 participants (974 eyes), worse VA was associated with worse mean score on the OSDI vision subscale (39.4 for VA 20/32 or worse vs. 32.4 for VA 20/16 or better; adjusted linear trend, P = .02); scores were not associated with contrast sensitivity. Severe meibomian gland plugging and abnormal secretions were associated with worse mean log contrast sensitivity (1.48 for severe vs. 1.54 for not plugged [P = .04] and 1.49 for obstructed vs. 1.57 for clear [P = .002], respectively). Longer TBUT was associated with better mean log contrast sensitivity (1.57 for TBUT >5 seconds and 1.51 for TBUT ≤2 seconds, P < .0001). CONCLUSIONS:Worse VA rather than worse contrast sensitivity drives vision-related symptoms in dry eye. Greater tear film instability was associated with worse contrast sensitivity

    Advances in the treatment of ocular dryness associated with Sjögren׳s syndrome.

    BACKGROUND: Sjögren´s syndrome (SS) is an autoimmune rheumatic disease that is characterised by decreased exocrine gland function and frequent ocular symptoms associated with eye dryness. Significantly, dry eyes can lead to corneal abrasions, infection, ulceration, chronic scarring and, in severe cases, perforation. The available conventional therapies have limited efficacy and there are no biologic therapies licensed for use in SS patients. MATERIALS AND METHODS: A literature search of PubMed (MEDLINE) and EMBASE electronic data bases was performed covering the period from January 1994 to September 2014. Evidence was graded in categories I-IV and a treatment algorithm, comprising first line, second line and rescue therapies for ocular dryness associated with SS was proposed. It is based on the current evidence of efficacy of different therapies and explores their link with the pathogenesis of ocular dryness associated with SS. RESULTS: Recent developments in the understanding of the pathogenesis of SS provided evidence that the ocular dryness is associated with pathologic infiltration and dysfunction of the lacrimal glands and changes in the tear composition, together with abnormalities involving the neurosecreting circuits. There is good evidence for the efficacy of topical artificial tears, antiinflammatories and Cyclosporine, and oral Pilocarpine and Cevimeline in controlling the symptoms of ocular dryness associated with SS. CONCLUSIONS: Conventional DMARDs are not particularly effective in addressing the symptoms of ocular dryness associated with SS, despite being commonly prescribed for other SS manifestations. Emerging evidence suggests that B cell and co-stimulatory targeted therapy may play a role in the future
