An integrative review of drug utilization by the elderly in primary health care

ABSTRACT OBJECTIVE To identify knowledge produced about drug utilization by the elderly in the primary health care context from 2006 to 2014. METHOD An integrative review of the PubMed, LILACS, BDENF, and SCOPUS databases, including qualitative research papers in Portuguese, English, and Spanish. It excluded papers with insufficient information regarding the methodological description. RESULTS Search found 633 papers that, after being subjected to the inclusion and exclusion criteria, made up a corpusof 76 publications, mostly in English and produced in the United States, England, and Brazil. Results were pooled in eight thematic categories showing the current trend of drug use in the elderly, notably the use of psychotropics, polypharmacy, the prevention of adverse events, and adoption of technologies to facilitate drug management by the elderly. Studies point out the risks posed to the elderly as a consequence of changes in metabolism and simultaneous use of several drugs. CONCLUSION There is strong concern about improving communications between professionals and the elderly in order to promote an exchange of information about therapy, and in this way prevent major health complications in this population.

Modulation of inflammatory pathways by the HIV protease inhibitors

Les inhibiteurs de la protéase du VIH (IP) constituent une des classes de traitements antirétroviraux parmi les plus utilisés au cours de l'infection par le VIH. Leur utilisation est associée à divers effets secondaires, notamment la dyslipidémie, la résistance à l'insuline, la lipodystrophie et certaines complications cardio-vasculaires. Ces molécules ont également des propriétés anti-tumorales, décrites chez des patients non infectés par le VIH. Pourtant, les mécanismes moléculaires à l'origine de ces effets annexes restent méconnus. Dans ce travail, nous démontrons que les IP, comme le Nelfinavir, le Ritonavir, le Lopinavir, le Saquinavir et l'Atazanavir, entrainent la production d'interleukine-lß (IL-lß), une puissante cytokine pro-inflammatoire, connue pour son rôle central dans les maladies inflammatoires. La sécrétion d'IL-lß requiert la formation de l'inflammasome, un complexe protéique intracellulaire servant de plateforme d'activation de la caspase-1 et, par la suite, à la maturation protéolytique de certaines cytokines, dont l'IL-lß. Dans les macrophages murins en culture primaire, ainsi que dans une lignée de monocytes humains, nous démontrons que les IP augmentent la maturation et la sécrétion de l'IL-lß via l'induction d'un inflammasome dépendant de ASC. De plus, nous établissons que les IP induisent spécifiquement l'activation de AIM2, un inflammasome détectant la présence intracytosolique d'ADN viral ou bactérien. Nos résultats démontrent l'existence d'une nouvelle voie d'activation de l'inflammasome AIM2 par un signal endogène dont la nature reste à définir. Ces données suggèrent que AIM2 pourrait jouer un rôle important dans la promotion de l'activité anti-tumorale ainsi que dans les autres effets annexes observés chez les patients traités par IP. -- HIV protease inhibitors (Pis) are among the most often used classes of antiretroviral drugs for HIV infection. Treatment of patients with HIV-PIs is associated with the development of metabolic side effects including dyslipidemia, insulin resistance, lipodystrophy and cardiovascular complications. In addition, these drugs have been reported to have anti¬tumoral properties in non-infected patients, however the molecular mechanisms causing these off-target effects are still unclear. Here we show that the HIV-PIs, such as Nelfinavir, Ritonavir, Lopinavir, Saquinavir and Atazanavir, activate the production of interleukin-lß (IL-lß), a potent pro-inflammatory cytokine that plays a central role in the pathogenesis of inflammatory diseases. The release of IL-lß depends on the activation of the inflammasome, a multiprotein complex that serves as a platform for caspase-1 activation and subsequent proteolytic maturation of cytokines including IL-lß. We found that in mouse primary macrophages as well as in a human monocytic cell line, the HIV-PIs augment the maturation and secretion of IL-lß by triggering an ASC-dependent inflammasome activation. Moreover, we show that the HIV-PIs specifically engage AIM2, a recently characterized inflammasome -forming protein that was described to detect the cytosolic release of bacterial and viral DNA. Our findings demonstrate a new pathway of activation of the AIM2 inflammasome by a yet to be defined endogenous signal and may suggest a possible role for AIM2 in promoting anti¬tumoral activity and off-target effects observed in HIV-PIs treated patients.

Estimation du débit de filtration glomérulaire par la formule DFG = K x T/Pcr [Estimation of glomerular filtration rate by the formula GFR = K x T/Pc].

BACKGROUND: Creatinine clearance is the most common method used to assess glomerular filtration rate (GFR). In children, GFR can also be estimated without urine collection, using the formula GFR (mL/min x 1.73 m2) = K x height [cm]/Pcr [mumol/L]), where Pcr represents the plasma creatinine concentration. K is usually calculated using creatinine clearance (Ccr) as an index of GFR. The aim of the present study was to evaluate the reliability of the formula, using the standard UV/P inulin clearance to calculate K. METHODS: Clearance data obtained in 200 patients (1 month to 23 years) during the years 1988-1994 were used to calculate the factor K as a function of age. Forty-four additional patients were studied prospectively in conditions of either hydropenia or water diuresis in order to evaluate the possible variation of K as a function of urine flow rate. RESULTS: When GFR was estimated by the standard inulin clearance, the calculated values of K was 39 (infants less than 6 months), 44 (1-2 years) and 47 (2-12 years). The correlation between the values of GFR, as estimated by the formula, and the values measured by the standard clearance of inulin was highly significant; the scatter of individual values was however substantial. When K was calculated using Ccr, the formula overestimated Cin at all urine flow rates. When calculated from Ccr, K varied as a function of urine flow rate (K = 50 at urine flow rates of 3.5 and K = 64 at urine flow rates of 8.5 mL/min x 1.73 m2). When calculated from Cin, in the same conditions, K remained constant with a value of 50. CONCLUSIONS: The formula GFR = K x H/Pcr can be used to estimate GFR. The scatter of values precludes however the use of the formula to estimate GFR in pathophysiological studies. The formula should only be used when K is calculated from Cin, and the plasma creatinine concentration is measured in well defined conditions of hydration.

Cashing by the hour: Why large law firms prefer hourly fees over contingent fees

Large law firms seem to prefer hourly fees over contingent fees. Thispaper provides a moral hazard explanation for this pattern of behavior.Contingent legal fees align the interests of the attorney with those ofthe client, but not necessarily with those of the partnership. We showthat the choice of hourly fees is a solution to an agency problem withmultiple principals, where the interests of one principal (law firm)collide with the interests of the other principal (client).
