TL;DR: A series of macrocyclic receptors designed to probe the influence of four factors, hydrogen bonding, charge, dimensionality, and topology, on anion binding indicate a number of corollaries with transition-metal coordination chemistry in terms of binding concepts such as the chelate effect and dual valencies.
Abstract: A series of macrocyclic receptors were designed to probe the influence of four factors, hydrogen bonding, charge, dimensionality, and topology, on anion binding. Monocyclic and bicyclic polyammonium and polyamide receptors were synthesized from either 2,2‘-diaminodiethylamine derivatives (dien) or 2,2‘,2‘ ‘-aminoethylamine (tren) building blocks, plus aromatic or heterocyclic spacers. Supramolecular complexes of these hosts with three simple anion topologies were probed: spherical (halides), trigonal planar (nitrate), and tetrahedral (sulfate). Results indicate a number of corollaries with transition-metal coordination chemistry in terms of binding concepts such as the chelate effect and dual valencies, as well as geometries for anion complexes that are strikingly similar to those observed in transition-metal coordination chemistry.

TL;DR: Twenty years ago, an anthropological note described the current dimensions of applied behavior analysis as it was prescribed and practiced in 1968: It was, or ought to become, applied, behavioral, analytic, technological, conceptual, effective, and capable of appropriately generalized outcomes
Abstract: Twenty years ago, an anthropological note described the current dimensions of applied behavior analysis as it was prescribed and practiced in 1968: It was, or ought to become, applied, behavioral, analytic, technological, conceptual, effective, and capable of appropriately generalized outcomes. A similar anthropological note today finds the same dimensions still prescriptive, and to an increasing extent, descriptive. Several new tactics have become evident, however, some in the realm of conceptual analysis, some in the sociological status of the discipline, and some in its understanding of the necessary systemic nature of any applied discipline that is to operate in the domain of important human behaviors.

TL;DR: An evidence-based review of the safety and efficacy of botulinum neurotoxin in the treatment of adult and childhood spasticity found the highest quality literature available for the respective indications was as follows.
Abstract: Objective: To perform an evidence-based review of the safety and efficacy of botulinum neurotoxin (BoNT) in the treatment of movement disorders. Methods: A literature search was performed including MEDLINE and Current Contents for therapeutic articles relevant to BoNT and selected movement disorders. Authors reviewed, abstracted, and classified articles based on American Academy of Neurology criteria (Class I–IV). Results: The highest quality literature available for the respective indications was as follows: blepharospasm (two Class II studies); hemifacial spasm (one Class II and one Class III study); cervical dystonia (seven Class I studies); focal upper extremity dystonia (one Class I and three Class II studies); focal lower extremity dystonia (one Class II study); laryngeal dystonia (one Class I study); motor tics (one Class II study); and upper extremity essential tremor (two Class II studies). Recommendations: Botulinum neurotoxin should be offered as a treatment option for the treatment of cervical dystonia (Level A), may be offered for blepharospasm, focal upper extremity dystonia, adductor laryngeal dystonia, and upper extremity essential tremor (Level B), and may be considered for hemifacial spasm, focal lower limb dystonia, and motor tics (Level C). While clinicians’ practice may suggest stronger recommendations in some of these indications, evidencebased conclusions are limited by the availability of data. Neurology ® 2008;70:1699–1706

TL;DR: Elderly patients who sustain blunt chest trauma with rib fxs have twice the mortality and thoracic morbidity of younger patients with similar injuries, and a significant increase in morbidity and mortality in both groups, but with different patterns for each group.
Abstract: BACKGROUND: We sought to ascertain the extent to which advanced age influences the morbidity and mortality after rib fractures (fxs), to define the relationship between number of rib fractures and morbidity and mortality, and to evaluate the influence of analgesic technique on outcome. METHODS: A retrospective cohort study involving all 277 patients > or = 65 years old with rib fxs admitted to a Level I trauma center over 10 years was undertaken. The control group consisted of 187 randomly selected patients, 18 to 64 years old, with rib fxs admitted over the same time period. Outcomes included pulmonary complications, number of ventilator days, length of intensive care unit and hospital stay (LOS), disposition, and mortality. The specific analgesic technique used was also examined. RESULTS: The two groups had similar mean number of rib fxs (3.6 elderly vs. 4.0 young), mean chest Abbreviated Injury Scores (3.0 vs. 3.0), and mean Injury Severity Score (20.7 vs. 21.4). However, mean number of ventilator days (4.3 vs. 3.1), intensive care unit days (6.1 vs. 4.0), and LOS (15.4 vs. 10.7 days) were longer for the elderly patients. Pneumonia occurred in 31% of elderly versus 17% of young (p 2 days) was associated with a 10% mortality versus 16% without the use of an epidural (p = 0.28). In the younger group (LOS >2 days), mortality with and without the use of an epidural was 0% and 5%, respectively. CONCLUSION: Elderly patients who sustain blunt chest trauma with rib fxs have twice the mortality and thoracic morbidity of younger patients with similar injuries. For each additional rib fracture in the elderly, mortality increases by 19% and the risk of pneumonia by 27%. As the number of rib fractures increases, there is a significant increase in morbidity and mortality in both groups, but with different patterns for each group. Further prospective study is needed to determine the utility of epidural analgesia in this population.
