This study aimed at learning about the feelings experienced by mothers while breastfeeding their premature babies in a rooming-in facility, by means of individual interviews with 33 mothers during the period of February to April 2006, at a maternity hospital in Natal/RN/Brazil. The main feelings referred by the mothers regarding their inability to breastfeed their premature babies immediately after delivery were: sorrow, guilt, disappointment, frustration, insecurity, and fear of touching, holding or harming the delicate babies while breastfeeding. However, the mother-child bond that was formed when the baby was discharged from the Neonatal Intensive Care Unit and taken to the rooming-in facility was reflected by feelings of fulfillment, pride, and satisfaction at experiencing the first breastfeeding.

PURPOSE: To evaluate subconjunctival mitomycin C (MMC) injection efficacy and safety in patients with failing glaucoma non-penetrating filtering blebs. METHODS: Twenty-eight eyes were consecutively recruited for this study. Only one eye for each patient was randomly selected. All the recruited patients had glaucoma and uncontrolled intraocular pressure after a non-penetrating filtering glaucoma surgery and/or a pathological aspect of the filtering bleb (i.e., vascularized and/or encysted). One or more MMC injections were performed under the conjunctiva closed to the bleb to improve filtration. Local effects and complications of subconjunctival MMC injections were analyzed. RESULTS: Out of the 28 patients, 21 (75%) had MMC also applied intraoperatively. The mean postoperative IOP before MMC injections was 17 +/- 6.6 mmHg. The final IOP after MMC injections was 13.9 +/- 2.9 mmHg after a mean follow-up of 6 months. A total of 67 subconjunctival MMC injections were performed with a mean of 2.9 (ranging from 1 to 5) injections per patient. The only complication found to be possibly related to MMC injections was two cases of corneal Dellen. CONCLUSION: From these preliminary results, subconjunctival MMC injections in selected cases appear to be not only safe but also effective in promoting further the postoperative IOP drop.

During a blood meal, Lutzomyia intermedia sand flies transmit Leishmania braziliensis, a parasite causing tegumentary leishmaniasis. In experimental leishmaniasis, pre-exposure to saliva of most blood-feeding sand flies results in parasite establishment in absence of any skin damages in mice challenged with dermotropic Leishmania species together with saliva. In contrast, pre-immunization with Lu. intermedia salivary gland sonicate (SGS) results in enhanced skin inflammatory exacerbation upon co-inoculation of Lu. intermedia SGS and L. braziliensis. These data highlight potential unique features of both L. braziliensis and Lu. intermedia. In this study, we investigated the genes modulated by Lu. intermedia SGS immunization to understand their potential impact on the subsequent cutaneous immune response following inoculation of both SGS and L. braziliensis. The cellular recruitment and global gene expression profile was analyzed in mice repeatedly inoculated or not with Lu. intermedia. Microarray gene analysis revealed the upregulation of a distinct set of IFN-inducible genes, an immune signature not seen to the same extent in control animals. Of note this INF-inducible gene set was not induced in SGS pre-immunized mice subsequently co-inoculated with SGS and L. braziliensis. These data suggest the parasite prevented the upregulation of this Lu. intermedia saliva-related immune signature. The presence of these IFN-inducible genes was further analyzed in peripheral blood mononuclear cells (PBMCs) sampled from uninfected human individuals living in a L. braziliensis-endemic region of Brazil thus regularly exposed to Lu. intermedia bites. PBMCs were cultured in presence or absence of Lu. intermedia SGS. Using qRT-PCR we established that the IFN-inducible genes induced in the skin of SGS pre-immunized mice, were also upregulated by SGS in PBMCs from human individuals regularly exposed to Lu. intermedia bites, but not in PBMCs of control subjects. These data demonstrate that repeated exposure to Lu. intermedia SGS induces the expression of potentially host-protective IFN-inducible genes.

Rapport de synthèseDrug uptake in a rodent sarcoma model after intravenous injection or isolated lungperfusion of free/liposomal doxorubicinIntroductionLa distribution de doxorubicine libre et doxorubicin liposomale pegylée (Liporubicin?) a été comparée après administration intraveineuse ou application via perfusion isolée du poumon (ILP) dans le parenchyme pulmonaire et dans la tumeur des poumons de rongeurs, porteurs d'une tumeur sarcomateuse.Matériel et méthodeUne tumeur sarcomateuse unique a été générée dans le poumon gauche de 36 rongeurs (Fisher rats) suivie, 10 jours plus tard, par application de doxorubicine ou Liporubicin? soit par perfusion isolée du poumon (n = 20) ou administration intraveineuse (n = 12). Deux différentes concentrations ont été utilisées (100 μg et 400 pg) à doses équimolaires pour les deux formulations de doxorubicine. La concentration des agents cytostatiques ont été mesurées dans la tumeur et le parenchyme pulmonaire à l'aide de chromatographic (HPLC).RésultatsLes résultats indiquent que pour doxorubicine libre, le taux de concentration dans la tumeur et le parenchyme pulmonaire est 3 fois (dosage de 100 μ§) et 10 fois (dosage de 400 plus élevé après ILP par rapport à l'administration intraveineuse. En revanche, pour Liporubicin , le taux de concentration est similaire dans la tumeur et le parenchyme pulmonaire entre ILP et administration intraveineuse, pour les deux doses appliquées.ConclusionPour ILP et administration intraveineuse, le ratio entre accumulation de l'agent cytostatique dans la tumeur versus dans le parenchyme pulmonaire a été comparé pour les deux formulations de doxorubicine ainsi que pour les deux dosages. Pour les deux formulations et dosages de doxorubicine, ILP aboutit à un ratio plus élevé par rapport à l'administration intraveineuse. Cependant, pour les deux formulations et dosages de doxorubicine, ILP résulte également en une distribution de l'agent cytostatique plus hétérogène dans le parenchyme pulmonaire comparé à l'administration intraveineuse.En résumé, l'application de doxorubicine par ILP aboutit donc à une accumulation tumorale élevée et à une augmentation du ratio tumeur-parenchyme pulmonaire, mais en même temps également à une distribution plus hétérogène dans le parenchyme pulmonaire par rapport à l'application intraveineuse. Ceci a été observé pour les deux formulations de doxorubicine et pour les deux dosages appliqué.

The past four decades have witnessed an explosive growth in the field of networkbased facility location modeling. This is not at all surprising since location policy is one of the most profitable areas of applied systems analysis in regional science and ample theoretical and applied challenges are offered. Location-allocation models seek the location of facilities and/or services (e.g., schools, hospitals, and warehouses) so as to optimize one or several objectives generally related to the efficiency of the system or to the allocation of resources. This paper concerns the location of facilities or services in discrete space or networks, that are related to the public sector, such as emergency services (ambulances, fire stations, and police units), school systems and postal facilities. The paper is structured as follows: first, we will focus on public facility location models that use some type of coverage criterion, with special emphasis in emergency services. The second section will examine models based on the P-Median problem and some of the issues faced by planners when implementing this formulation in real world locational decisions. Finally, the last section will examine new trends in public sector facility location modeling.
