Mediterranean springs: Keystone ecosystems and biodiversity refugia threatened by global change.

Mediterranean spring ecosystems are unique habitats at the interface between surface water and groundwater. These ecosystems support a remarkable array of biodiversity and provide important ecological functions and ecosystem services. Spring ecosystems are influenced by abiotic, biotic, and anthropogenic factors such as the lithology of their draining aquifers, their climate, and the land use of their recharge area, all of which affect the water chemistry of the aquifer and the spring discharges. One of the most relevant characteristics of spring ecosystems is the temporal stability of environmental conditions, including physicochemical features of the spring water, across seasons and years. This stability allows a wide range of species to benefit from these ecosystems (particularly during dry periods), fostering an unusually high number of endemic species. However, global change poses important threats to these freshwater ecosystems. Changes in temperature, evapotranspiration, and precipitation patterns can alter the water balance and chemistry of spring water. Eutrophication due to agricultural practices and emergent pollutants, such as pharmaceuticals, personal care products, and pesticides, is also a growing concern for the preservation of spring biodiversity. Here, we provide a synthesis of the main characteristics and functioning of Mediterranean spring ecosystems. We then describe their ecological value and biodiversity patterns and highlight the main risks these ecosystems face. Moreover, we identify existing knowledge gaps to guide future research in order to fully uncover the hidden biodiversity within these habitats and understand the main drivers that govern them. Finally, we provide a brief summary of recommended actions that should be taken to effectively manage and preserve Mediterranean spring ecosystems for future generations. Even though studies on Mediterranean spring ecosystems are still scarce, our review shows there are sufficient data to conclude that their future viability as functional ecosystems is under severe threat.

Optimizing drug therapy in frail patients with type 2 diabetes mellitus.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is closely linked with ageing. In frail diabetic patients, the risks of intensive antidiabetic therapy outweigh the potential benefits. AIMS: To study the prevalence of T2DM in frail elderly patients, to identify inappropriate prescription (IP) of antidiabetic drugs and to study the relationship between patients' frailty index (FI) with polypharmacy and IP. METHODS: This was a prospective, descriptive, observational study of elderly patients. Each patient's antidiabetic treatment was analysed by applying the patient-centred prescription model (PCP), which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal. RESULTS: 210 patients with T2DM were included (25.15% prevalence). They were characterised by high multimorbidity and frailty. 93.3% presented polypharmacy and 51% excessive polypharmacy. IP was identified in 66.2% of patients. A statistically significant relationship was found between the progression in FI degree and IP prevalence (p < 0.05. During the admission, drug therapy regimens were modified in 97.1% of cases with IP (n = 136). DISCUSSION: These results suggest that in clinical practice T2DM treatment is not individualised, but rather is based on the same general recommendations for the population as a whole. CONCLUSIONS: There is a high prevalence of T2DM in the elderly. As the frailty of patients increases, so does the prevalence of IP. The application of PCP model enables drug therapy optimization in frail patients according to their main therapeutic goal, and contributes to provide clinical evidences on the applicability of a set of knowledge areas from the theoretical framework to the daily clinical practice.

A biological tool to assess flow connectivity in reference temporary streams from the Mediterranean Basin.

Many streams in the Mediterranean Basin have temporary flow regimes. While timing for seasonal drought is predictable, they undergo strong inter-annual variability in flow intensity. This high hydrological variability and associated ecological responses challenge the ecological status assessment of temporary streams, particularly when setting reference conditions. This study examined the effects of flow connectivity in aquatic macroinvertebrates from seven reference temporary streams across the Mediterranean Basin where hydrological variability and flow conditions are well studied. We tested for the effect of flow cessation on two streamflow indices and on community composition, and, by performing random forest and classification tree analyses we identified important biological predictors for classifying the aquatic state either as flowing or disconnected pools. Flow cessation was critical for one of the streamflow indices studied and for community composition. Macroinvertebrate families found to be important for classifying the aquatic state were Hydrophilidae, Simuliidae, Hydropsychidae, Planorbiidae, Heptageniidae and Gerridae. For biological traits, trait categories associated to feeding habits, food, locomotion and substrate relation were the most important and provided more accurate predictions compared to taxonomy. A combination of selected metrics and associated thresholds based on the most important biological predictors (i.e. Bio-AS Tool) were proposed in order to assess the aquatic state in reference temporary streams, especially in the absence of hydrological data. Although further development is needed, the tool can be of particular interest for monitoring, restoration, and conservation purposes, representing an important step towards an adequate management of temporary rivers not only in the Mediterranean Basin but also in other regions vulnerable to the effects of climate change.

Esencia de menta al 1, 6% como espasmolítico intestinalen la colangiopancreatografía retrógrada endoscópica / 1.6% Peppermint oil solution as intestinal spasmolytic in retrograde endoscopic cholangiopancreatography

Objetivos: La aparición de peristaltismo intestinal puede dificultar la realización de exploraciones o intervenciones mediante colangiopancreatografía retrógrada endoscópica(CPRE). Con el fin de disminuirlo es frecuente la utilización de espasmolíticos sistémicos, pese a los efectos adversos anticolinérgicos que presentan. Se propuso formular una preparación de esencia de menta al 1,6% de uso local para evitar estos efectos adversos. Método: Se formuló la preparación de la esencia de menta al 1,6% según la bibliografía encontrada. La efectividad de la fórmula fue valorada de manera semicualitativa según la disminución del peristaltismo. Resultados: Se ensayaron 2 emulgentes siendo polisorbato el más adecuado. El estudio piloto llevado a cabo en 8 pacientes demostró su efectividad y seguridad en la disminución del peristaltismo intestinal. Conclusiones: La esencia de menta al 1,6% constituye una alternativa efectiva y segura a la utilización de espasmolíticos sistémicos. Se requieren posteriores estudios incluyendo un mayor número de pacientes para establecer su utilidad en la práctica clínica habitual (AU)

Objectives: Intestinal peristalsis can impede explorations and interventions using retrograde endoscopic cholangiopancreatography. Systemic spasmolytics are frequently employed to reduce this phenomenon, in spite of the adverse anti-cholinergic effects they are associated with. We proposed a formula using 1.6% peppermint oil solution with local use in order to avoid these adverse side effects. Method: We formulated a preparation of 1.6% peppermint oil solution in accordance with the medical literature. The effectiveness of the formula was evaluated in a semi-qualitative manneraccording to the reduction in peristalsis. Results: We tested two different emulgents, and polysorbate provided the best results. The pilot study carried out with 8 patients demonstrated its effectiveness and safety in reducing intestinal peristalsis. Conclusions: 1.6% peppermint oil solution constitutes an effective and safe alternative to the use of systemic spasmolytics. More studies are needed with a larger sample size in order to establish its usefulness in normal clinical practice (AU)

Intervención farmacéutica en pacientes quirúrgicos con alteraciones electrolíticas / Drug treatment in surgical patients with electrolyte imbalances

Objetivo Determinar cuali y cuantitativamente las alteraciones electrolíticas (relacionadas con potasio, fósforo, magnesio y calcio) en pacientes ingresados en áreas de cirugía general y gastrointestinal, el porcentaje de dichas alteraciones detectado por el equipo médico y el grado de aceptación de las recomendaciones realizadas desde el Servicio de Farmacia Hospitalaria. Método Estudio prospectivo de 7 meses. Toda alteración detectada se registró en una hoja de recogida de datos (datos personales, sala de hospitalización, tipo de alteración, detección por equipo médico, tipo de intervención farmacéutica, modo de notificación, aceptación de la intervención, fecha de corrección de la alteración, paciente en tratamiento con nutrición parenteral).Resultados Se detectaron 100 alteraciones en 66 pacientes (231 analíticas revisadas). Se realizaron un total de 78 intervenciones. La mayoría de alteraciones se debieron a hipokalemias e hipomagnesemias, siendo la hipofosfatemia la alteración más frecuente en pacientes portadores de nutrición parenteral. El grado de aceptación de la intervención farmacéutica por parte del equipo médico fue superior cuando la información fue oral (100 vs 35% escrita). Se consiguió el doble de analíticas de comprobación tras las intervenciones (RR 2,1; IC 95% 1,11-3,94, p=0,006). La aceptación de la intervención comportó una mayor proporción de resoluciones de la alteración respecto a los casos en los que no se aceptó (RR 1,5; IC 95% 1,01-2,24, p=0,04).Conclusiones Este estudio pone de manifiesto que las alteraciones electrolíticas en pacientes quirúrgicos son frecuentes y su grado de detección y seguimiento por parte del equipo médico es bajo. Por ello, el farmacéutico podría contribuir en la mejora de dichos aspectos participando en la atención a estos pacientes (AU)

Objective To qualitatively and quantitatively determine electrolyte imbalances (potassium, phosphorus, magnesium and calcium) in patients admitted for general and gastrointestinal surgery, the degree of these imbalances in percentage detected by medical staff, and the acceptance of the recommendations made by the Hospital Pharmacy Department. Method Seven-month prospective study. Any alteration detected was recorded on a data collection form (personal data, hospital ward, type of alteration, detection by medical staff, type of pharmaceutical intervention, form of notification, acceptance of the intervention, date of imbalance correction, patient receiving parenteral nutrition).Results100 imbalances were detected in 66 patients (231 analytical tests revised). A total of 78 interventions were carried out. Most changes were due to hypokalaemia and hypomagnesaemia, hypophosphataemia being the most frequent abnormality in patients receiving parenteral nutrition. The acceptance of pharmaceutical intervention was higher if the information was oral (100% vs. 35% written). Twice the number of analytical tests were performed after interventions (RR: 2.1, 95% CI: 1.11 to 3.94, P=.006). When pharmaceutical intervention was accepted there was a greater number of imbalance resolutions in comparison with those cases which did not accept (RR: 1.5, 95% CI: 1.01 to 2.24, P=.04).Conclusions This study shows that electrolyte imbalances are common in surgical patients and the level of detection and monitoring by medical staff is low. Therefore, the pharmacist could help in improving this aspect (AU)

Ecological profiles of caddisfly larvae in Mediterranean streams: implications for bioassessment methods.

Caddisflies are a well represented group with high species diversity in Mediterranean climate rivers. Although they are widely used in water quality assessment, little is known of the ecological profiles of families or species. We present a simple score for ecological profiles which measures intolerance to water quality. The ecological profiles of caddisflies are diverse and the degree of tolerance at the family level is related to species diversity and the tolerance of individual species to water quality. Comparisons with the scores used in the biotic index IBMWP show general agreement between the degree of intolerance of a family and its score in the IBMWP, with few exceptions. Studies on tolerance are required to elucidate the autecology of taxa, and to develop biological indices, especially in areas with high species diversity.
