We report the first total synthesis of (+)-granatumine A, a limonoid alkaloid with PTP-1B inhibitory activity, in 10 steps. Over the course of this study, two key methodological advances were made: a cost effective procedure for ketone alpha,beta-dehydrogenation using allyl-Pd catalysis, and a Pd-catalyzed protocol to convert epoxyketones to 1,3-diketones. The central tetrasubstituted pyridine is formed by a convergent Knoevenagel condensation and carbonyl-selective electrocyclization cascade, which was followed by a direct transformation of a 2<i>H</i>-pyran to a pyridine. These studies have led to the structural revision of two members of this family.

AbstractA convenient approach to assemble 1,2,3-triazole-fused 4H-3,1-benzoxazines has been developed. Diverse alcohol-tethered 5-iodotriazoles, readily accessible by a modified protocol of Cu-catalyzed (3+2)-cycloaddition, were utilized as precursors of the target fused heterocycles. The intramolecular C–O coupling proceeded efficiently under base-mediated transition-metal-free conditions, furnishing cyclization products in yields up to 96%. Suppression of the competing reductive cleavage of the C–I bond was achieved by the use of Na2CO3 in acetonitrile at 100 °C. This practical and cost-effective procedure features a broad substrate scope and valuable functional group tolerance.

<p><strong>ABSTRACT</strong></p><p><strong>Background:</strong> To date, there have been few economic evaluations, from a Canadian perspective, of direct oral anticoagulants (DOACs) for the prevention of recurrent venous thromboembolism (VTE) in patients with acute unprovoked VTE. As a result, there is a lack of consensus about which treatment strategy should be adopted in the clinical setting.</p><p><strong>Objectives:</strong> To assess the cost-effectiveness of currently approved anti - coagulant options, in terms of cost per quality-adjusted life-year (QALY) gained, for the prevention of recurrent VTE in patients with unprovoked events managed on an outpatient basis.</p><p><strong>Methods:</strong> Microsoft Excel was used to develop a Markov model. Model parameters were determined using published literature, local hospital data, expert opinion, and chart review. The analysis considered the costs associated with pharmaceuticals, laboratory testing, hematologist fees, and treatment of recurrent VTE and major bleeding events. Effectiveness was measured in terms of QALYs, and incremental cost-effectiveness ratios (ICERs) were calculated.</p><p><strong>Results:</strong> For treatment lasting 3 months, apixaban represented the most cost-effective DOAC relative to low-molecular-weight heparin (LMWH) + vitamin K antagonist, with an ICER of $7379.66. For 6 months of treatment, apixaban again represented the most cost-effective treatment, with an ICER of $84.08 per QALY gained, and this drug dominated all the other strategies at 12 months. For lifetime treatment, DOACs were unlikely to be cost-effective, given a maximum willingness to pay of $50 000 to $100 000 per QALY. In a probabilistic sensitivity analysis at 6 months, 46.4% of iterations resulted in apixaban having lower costs and better outcomes than LMWH + vitamin K antagonist, and 78.6% of iterations resulted in an ICER below $100 000</p><p><strong>Conclusions:</strong> The findings of this study suggest that apixaban is likely cost-effective for treatment durations of 3, 6, and 12 months. However, for indefinite treatment, DOACs were unlikely to be cost-effective.</p><p><strong>RÉSUMÉ</strong></p><p><strong>Contexte :</strong> À ce jour, on a réalisé peu d’évaluations économiques, d’un point de vue canadien, sur les anticoagulants oraux directs (AOD) utilisés dans la prévention de la thromboembolie veineuse (TEV) récurrente chez les patients atteints de TEV idiopathique aiguë. Pour cette raison, aucun consensus n’a été établi quant à la stratégie thérapeutique à adopter en milieu clinique.</p><p><strong>Objectif :</strong> Évaluer le rapport coût-efficacité des anticoagulothérapies actuellement approuvées, en ce qui a trait au coût par année de vie pondérée par la qualité (QALY) gagnée, pour la prévention de la TEV récurrente chez les patients ayant subi des événements idiopathiques qui ont été traités en consultation externe.</p><p><strong>Méthodes :</strong> Le logiciel Excel de Microsoft a servi à créer un modèle de Markov. Les paramètres du modèle ont été établis à l’aide de la littérature, de données de l’hôpital local, d’opinions d’experts et d’une analyse de dossiers médicaux. L’analyse prenait en compte les coûts associés aux médicaments, aux examens de laboratoire, aux honoraires d’hématologues et au traitement de la TEV récurrente et d’hémorragies importantes. L’efficacité était mesurée en nombre de QALY et les rapports coûtefficacité différentiels ont été calculés.</p><p><strong>Résultats :</strong> Pour un traitement de trois mois, l’apixaban représentait l’AOD offrant le meilleur rapport coût-efficacité comparativement à l’héparine de bas poids moléculaire (HBPM) + un antagoniste de la vitamine K; il présentait un rapport coût-efficacité différentiel de 7379,66 $. Pour un traitement de six mois, l’apixaban représentait à nouveau le traitement le plus efficace par rapport au coût; il présentait un rapport coût-efficacité différentiel de 84,08 $ par QALY gagnée. Ce médicament surclassait toutes les autres stratégies après douze mois de traitement. En ce qui concerne un traitement à vie, les AOD offraient probablement un moins bon rapport coût-efficacité, compte tenu d’une propension à payer maximale se situant entre 50 000 $ et 100 000 $ par QALY. Dans une analyse de sensibilité probabiliste au sixième mois de traitement, 46,4 % des itérations se traduisaient par des coûts moins élevés et de meilleurs résultats pour l’apixaban relativement à l’HBPM + un antagoniste de la vitamine K. De plus, 78,6 % des itérations se traduisaient par un rapport coût-efficacité différentiel de moins de 100 000 $.</p><p><strong>Conclusions :</strong> Ces résultats laissent croire que l’apixaban présente probablement un rapport coût-efficacité intéressant pour les traitements d’une durée de 3, 6 et 12 mois. Cependant, en ce qui concerne un traitement d’une durée indéterminée, les AOD ne sont sans doute pas avantageux.</p>

Muller's introduction in 1953 of ambulatory phlebectomy, although initially not appreciated nor readily accepted, revolutionized the surgical treatment of varicosities of the lower extremities forever. However, many years had to pass before this would be reality. This article follows the treatment of incompetent saphenofemoral and saphenopopliteal junctions. Ambulatory phlebectomy is an efficient, efficacious, cosmetically superior, appropriate, and cost-effective procedure for the treatment of the varicosities of the lower extremities. It is performed under local anesthesia in an office setting, with the patient returning home the same day. In many instances, the patient is able to return to work the day following the operation.

The Law Amending the General Administrative Procedure Act refers to a variety of provisions. New solutions should contribute to a more rapid, more efficient and more cost-effective procedure. Primarily due to elimination of the inconsistent use of individual provisions in practice, the amending law regulates more definitely the issues of authorising the persons to manage and make decisions at different decision-making levels in administrative procedures in municipalities. The law also develops electronic operations and it especially amends the electronic service provisions. There is a fairly large number of amendments in the Service Chapter. And an important novelty needs to be emphasized. This is the institute of the waiver of the right to appeal which the General Administrative Procedure Act did not know. However, it is well-known in foreign legal regulations and in the Construction Act adopted in our country. KEY WORDS: • administrative procedure • electronic operations • right to appeal
