Prescripción de medicamentos en las farmacias : una realidad preocupante

Se presume que la prescripción de medicamentos sin receta médica en las farmacias es una práctica frecuente. El objetivo fue conocer la conducta del personal de las farmacias ante una consulta realizada por estudiantes de medicina entrenados para actuar como pacientes simulados de las siguientes situaciones: 1: Infección respiratoria alta, 2: Diarrea aguda; 3: Disuria, 4: Ulcera genital, 5: Hipertensión arterial, 6: Cefalea aguda, 7: Artralgia de tobillo. Se efectuaron 100 entrevistas y cada una de las situaciones se realizó al menos 12 veces. En solo el 28% de los casos no se indicó tratamiento y las 72 prescripciones fueron realizadas por 38 farmacéuticos y 34 no profesionales. La medicación se consideró inadecuada en 58.3%, iatrogénica en 51.4% y la posología incorrecta en 50%. Los fármacos más indicados fueron antibióticos (23.6%), AINES (20.8%), antidiarreicos (11.8%) y antigripales (9.7%). Las situaciones 7 (100%), 1 (93.3%) y 2 (84.6%) tuvieron la mayor frecuencia de indicación de tratamiento y fue significativa la negativa a medicar en las situaciones 4 (OR, 0.16) y 5 (OR, 0.22) (p<0.05). La prescripción fue incorrecta en el 100% de las situaciones 2 y 4 y iatrogénica en el 100% de las situaciones 2, 4 y 5. En 48 casos se sugirió consulta médica y la situación 5 tuvo 4.27 veces más posibilidades de ser derivada (p= 0.01). Este estudio demuestra que en las farmacias del gran Mendoza es común la venta de medicamentos sin prescripción médica lo que compromete la seguridad y salud de las personas.Drugs prescription by the pharmacy’s staff without medical supervision is a very common situation. For this reason we performed a study to assess the behaviour of pharmacy’s staff by means of a structured enquiry regarding seven common ambulatory medical problems. Voluntary medical students were trained to simulate the following medical situations: 1: Upper respiratory tract infection, 2: Acute diarrhea, 3: Dysuria, 4: Genital ulceration, 5: Arterial hypertension, 6: Acute cephalea, 7: Ankle arthralgia. 100 interviews were performed and every situation at least 12 times. Only in 28% of the cases no treatment was prescribed. The 72 prescriptions were performed by 38 pharmacists, 20 technicians and 14 unskilled employees. In 58.3% of the cases the suggested medication was considered inadequate, in 51.4% was iatrogenic and in 50% the dose was wrong. The most prescribed medications were antibiotics (23.6%), NSAIDs (20.8%), anti diarrhea medications (11.8%) and common cold drugs (9.7%). The highest rates of prescription were reached in situation 7 (100%), 1 (93.7%) and 2 (84.6%). The prescription rates in situations 4 (OR, 0.16) and 5 (OR, 0.22) were significantly lower (p < 0.05). The prescription was incorrect in 100% of situations 2 and 4 and was considered iatrogenic in 100% of situations 2, 4 and 5. In 48 cases a medical consultation was proposed, mainly in situation 5 (OR, 4.27; p= 0.01). This study shows that in pharmacies of Mendoza the prescription and selling of drugs without clinical indication is quite common and seriously influences patient's safety and health.Fil: Alós, María B..

Ethylene biosynthesis and perception during ripening of loquat fruit (Eriobotrya japonica Lindl.)

[EN] In order to gain insights into the controversial ripening behavior of loquat fruits, in the present study we have analyzed the expression of three genes related to ethylene biosynthesis (ACS1, ACO1 and ACO2), two ethylene receptors (ERS1a and ERS1b), one signal transduction component (CTR1) and one transcription factor (EIL1) in peel and pulp of loquat fruit during natural ripening and also in fruits treated with ethylene (10 mu LL-1) and 1-MCP (10 mu LL-1), an ethylene action inhibitor. In fruits attached to or detached from the tree, a slight increase in ethylene production was detected at the yellow stage, but the respiration rate declined progressively during ripening. Accumulation of transcripts of ethylene biosynthetic genes did not correlate with changes in ethylene production, since the maximum accumulation of ACS1 and ACO1 mRNA was detected in fully coloured fruits. Expression of ethylene receptor and signaling genes followed a different pattern in peel and pulp tissues. After fruit detachment and incubation at 20 degrees C for up to 6 days, ACS1 mRNA slightly increased, ACO1 experienced a substantial increment and ACO2 declined. In the peel, these changes were advanced by exogenous ethylene and partially inhibited by 1-MCP. In the pulp, 1-MCP repressed most of the changes in the expression of biosynthetic genes, while ethylene had almost no effects. Expression of ethylene perception and signaling genes was barely affected by ethylene or 1-MCP. Collectively, a differential transcriptional regulation of ethylene biosynthetic genes operates in peel and pulp, and support the notion of non-climacteric ripening in loquat fruits. Ethylene action, however, appears to be required to sustain or maintain the expression of specific genes.

Low Cost Semi Automated Assembly Unit for Small Size Back Contact Modules and Low Cost Interconnection Approach

AbstractWe present our low cost assembly unit to manufacture back contact solar modules based on the conductive backsheet (CBS) approach. This in house developed apparatus was built to assemble test modules containing one up to four 6 inch back contact solar cells. The system is a retrofit of a commercially available CNC system which is equipped with a cell grabber and a manual dispensing system (by Nordson). The total cost of the setup was roughly 4000 € excluding the dispenser unit. Using this equipment we assembled several small size modules containing one and four Zebra cells, which are low cost 6 inch IBC solar cells developed at ISC Konstanz [1,2]. The contact between copper backsheet and back contact cell of the one cell modules we present here is formed by low temperature solder paste (LTSP). First cell to module (CTM) loss evaluations and reliability results suggest that this material could be a viable alternative to electrically conductive adhesive (ECA) which is currently the most commonly used material for this purpose

The Category of Node-and-Choice Forms, with Subcategories for Choice-Sequence Forms and Choice-Set Forms

The literature specifies extensive-form games in many styles, and eventually I hope to formally translate games across those styles. Toward that end, this paper defines $\mathbf{NCF}$, the category of node-and-choice forms. The category's objects are extensive forms in essentially any style, and the category's isomorphisms are made to accord with the literature's small handful of ad hoc style equivalences. Further, this paper develops two full subcategories: $\mathbf{CsqF}$ for forms whose nodes are choice-sequences, and $\mathbf{CsetF}$ for forms whose nodes are choice-sets. I show that $\mathbf{NCF}$ is "isomorphically enclosed" in $\mathbf{CsqF}$ in the sense that each $\mathbf{NCF}$ form is isomorphic to a $\mathbf{CsqF}$ form. Similarly, I show that $\mathbf{CsqF_{\tilde a}}$ is isomorphically enclosed in $\mathbf{CsetF}$ in the sense that each $\mathbf{CsqF}$ form with no-absentmindedness is isomorphic to a $\mathbf{CsetF}$ form. The converses are found to be almost immediate, and the resulting equivalences unify and simplify two ad hoc style equivalences in Kline and Luckraz 2016 and Streufert 2019. Aside from the larger agenda, this paper already makes three practical contributions. Style equivalences are made easier to derive by [1] a natural concept of isomorphic invariance and [2] the composability of isomorphic enclosures. In addition, [3] some new consequences of equivalence are systematically deduced.Comment: 43 pages, 9 figure

Intrinsic noise-induced phase transitions: beyond the noise interpretation

We discuss intrinsic noise effects in stochastic multiplicative-noise partial differential equations, which are qualitatively independent of the noise interpretation (Ito vs. Stratonovich), in particular in the context of noise-induced ordering phase transitions. We study a model which, contrary to all cases known so far, exhibits such ordering transitions when the noise is interpreted not only according to Stratonovich, but also to Ito. The main feature of this model is the absence of a linear instability at the transition point. The dynamical properties of the resulting noise-induced growth processes are studied and compared in the two interpretations and with a reference Ginzburg-Landau type model. A detailed discussion of new numerical algorithms used in both interpretations is also presented.Comment: 9 pages, 8 figures, to be published in Phys. Rev.

Tracking aquatic animals for fisheries management in European waters

Acoustic telemetry (AT) has emerged as a valuable tool for monitoring aquatic animals in both European inland and marine waters over the past two decades. The European Tracking Network (ETN) initiative has played a pivotal role in promoting collaboration among AT researchers in Europe and has led to a significant increase in the number of tagged and observed aquatic animals in transboundary European waters. While AT benefits decision-making and delivers essential data to management bodies, its potential for management decision-making mechanisms has yet to be fully harnessed. We reviewed existing research, studies, and organisational initiatives related to aquatic animal tracking and their utility in fisheries management in European waters. We found that AT has already contributed to many aspects of fisheries management, such as improved understanding of stock dynamics, identification of critical habitats, assessment of migration routes, and evaluation of the effectiveness of conservation measures. However, broader utilisation of tracking technologies is needed. By leveraging the full potential of AT, managers can make more informed decisions to protect, restore, and sustainably manage European waters and creatures that live therein

Reduced Normal Forms Are Not Extensive Forms

Fundamental results in the theory of extensive form games have singled out the reduced normal form as the key representation of a game in terms of strategic equivalence. In a precise sense, the reduced normal form contains all strategically relevant information. This note shows that a difficulty with the concept has been overlooked so far: given a reduced normal form alone, it may be impossible to reconstruct the game’s extensive form representation

Recommendations of the Spanish Antibiogram Committee (COESANT) for selecting antimicrobial agents and concentrations for in vitro susceptibility studies using automated systems

Automated antimicrobial susceptibility testing devices are widely implemented in clinical microbiology laboratories in Spain, mainly using EUCAST (European Committee on Antimicrobial Susceptibility Testing) breakpoints. In 2007, a group of experts published recommendations for including antimicrobial agents and selecting concentrations in these systems. Under the patronage of the Spanish Antibiogram Committee (Comité Español del Antibiograma, COESANT) and the Study Group on Mechanisms of Action and Resistance to Antimicrobial Agents (GEMARA) from the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), and aligned with the Spanish National Plan against Antimicrobial Resistance (PRAN), a group of experts have updated this document. The main modifications from the previous version comprise the inclusion of new antimicrobial agents, adaptation of the ranges of concentrations to cover the EUCAST breakpoints and epidemiological cut-off values (ECOFFs), and the inference of new resistance mechanisms. This proposal should be considered by different manufacturers and users when designing new panels or cards. In addition, recommendations for selective reporting are also included. With this approach, the implementation of EUCAST breakpoints will be easier, increasing the quality of antimicrobial susceptibility testing data and their microbiological interpretation. It will also benefit epidemiological surveillance studies as well as the clinical use of antimicrobials aligned with antimicrobial stewardship programs
