RESUMO

STUDY QUESTION: In lesbian couples, is shared motherhood IVF (SMI) associated with an increase in perinatal complications compared with artificial insemination with donor sperm (AID)? SUMMARY ANSWER: Singleton pregnancies in SMI and AID had very similar outcomes, except for a non-significant increase in the rate of preeclampsia/hypertension (PE/HT) in SMI (recipient's age-adjusted odds ratio (OR) = 1.9, 95% CI = 0.7-5.2; P = 0.19), but twin SMI pregnancies had a much higher frequency of PE/HT than AID twins (recipient's age-adjusted OR = 21.7, 95% CI = 2.8-289.4; P = 0.01). WHAT IS KNOWN ALREADY: Oocyte donation (OD) pregnancies are associated with an increase in perinatal complications, in particular, preterm delivery and low birth weight, and PE/HT. However, it is unclear to what extent these complications are due to OD process or to the conditions why OD was performed, such as advanced age and underlying health conditions. Unfortunately, the literature concerning perinatal outcomes in SMI is scarce. STUDY DESIGN, SIZE, DURATION: Retrospective study involving 660 SMI cycles (299 pregnancies) and 4349 AID cycles (949 pregnancies) assisted over a 10-year period. PARTICIPANTS/MATERIALS, SETTING, METHODS: All cycles fulfilling the inclusion criteria performed in lesbian couples seeking fertility treatment in 17 Spanish clinics of the same group. Pregnancy rates of SMI and AID cycles were compared. Perinatal outcomes were compared: gestational length, newborn weight, preterm and low birth rates, PE/HT rates, cesarean section rates, perinatal mortality, and newborn malformations. MAIN RESULTS AND THE ROLE OF CHANCE: Pregnancy rates were higher in SMI than in AID (45.3% versus 21.8%, P < 0.001). There was a non-significant trend to higher multiple rate in AID (4.7% versus 8.5%, P = 0.08). In single pregnancies, there were no differences between SMI and AID in gestational age (278 days (268-285) versus 279 (272-284), P = 0.24), preterm rate (8.3% versus 7.3%, P = 0.80), preterm <28 weeks (0.6% versus 0.4%, P = 1.00), newborn weight (3195 g (2915-3620) versus 3270 g (2980-3600), P = 0.296), low birth rate (6.4% versus 6.4%, P = 1.00), extremely low birth weight (0.6% versus 0.5%, P = 1.00), and the distribution of newborns by weight groups. Cesarean section rate, newborn malformation rate, and perinatal mortality were also similar in SMI and AID. Additionally, there was non-significant trend in hypertensive disorders to an increase in PE/HT among SMI (recipient's age-adjusted OR = 1.9, 95% CI = 0.7-5.2). Overall, perinatal data are consistent with what is reported in the general population. In twin pregnancies, the aforementioned perinatal parameters were also very similar in SMI and AID. However, SMI twin pregnancies had a very high risk of PE/HT when compared with AID (recipient's age-adjusted OR = 21.7, 95% CI = 2.8-289.4, P = 0.01). LIMITATIONS, REASONS FOR CAUTION: Our data regarding the pregnancy course were obtained from information registered in the delivery report as well as from what was reported by the patients themselves, so a certain degree of inaccuracy cannot be ruled out. Additionally, in some parameters, there was up to 10% of data missing. However, since the methodology of reporting was the same in SMI and AID groups, one should not expect a differential reporting bias. It cannot be ruled out that the risk of PE/HT in simple gestations would be significant in a larger study. Additionally, in the SMI group allocation to the transfer of 2 embryos was not randomized so some bias is possible. WIDER IMPLICATIONS OF THE FINDINGS: SMI, if single embryo transfer is performed, seems to be is a safe procedure. Double embryo transfer should not be performed in SMI. Our data suggest that the majority of complications in OD could be related more with recipient status than with OD itself, since with SMI (performed in women without fertility problems) the perinatal complications were much lower than usually described in OD.

RESUMO

BACKGROUND: Older people receive care from multiple providers which often results in a lack of coordination. The Information and Communication Technology (ICT) enabled value-based methodology for integrated care (ValueCare) project aims to develop and implement efficient outcome-based, integrated health and social care for older people with multimorbidity, and/or frailty, and/or mild to moderate cognitive impairment in seven sites (Athens, Greece; Coimbra, Portugal; Cork/Kerry, Ireland; Rijeka, Croatia; Rotterdam, the Netherlands; Treviso, Italy; and Valencia, Spain). We will evaluate the implementation and the outcomes of the ValueCare approach. This paper presents the study protocol of the ValueCare project; a protocol for a pre-post controlled study in seven large-scale sites in Europe over the period between 2021 and 2023. METHODS: A pre-post controlled study design including three time points (baseline, post-intervention after 12 months, and follow-up after 18 months) and two groups (intervention and control group) will be utilised. In each site, (net) 240 older people (120 in the intervention group and 120 in the control group), 50-70 informal caregivers (e.g. relatives, friends), and 30-40 health and social care practitioners will be invited to participate and provide informed consent. Self-reported outcomes will be measured in multiple domains; for older people: health, wellbeing, quality of life, lifestyle behaviour, and health and social care use; for informal caregivers and health and social care practitioners: wellbeing, perceived burden and (job) satisfaction. In addition, implementation outcomes will be measured in terms of acceptability, appropriateness, feasibility, fidelity, and costs. To evaluate differences in outcomes between the intervention and control group (multilevel) logistic and linear regression analyses will be used. Qualitative analysis will be performed on the focus group data. DISCUSSION: This study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people, their informal caregivers, and health and social care practitioners in seven different European settings. TRIAL REGISTRATION: ISRCTN registry number is 25089186 . Date of trial registration is 16/11/2021.

RESUMO

STUDY QUESTION: What are the key considerations for developing an enhanced transcriptomic method for secretory endometrial tissue dating? SUMMARY ANSWER: Multiple gene expression signature combinations can serve as biomarkers for endometrial dating, but their predictive performance is variable and depends on the number and identity of the genes included in the prediction model, the dataset characteristics and the technology employed for measuring gene expression. WHAT IS KNOWN ALREADY: Among the new generation of transcriptomic endometrial dating (TED) tools developed in the last decade, there exists variation in the technology used for measuring gene expression, the gene makeup and the prediction model design. A detailed study, comparing prediction performance across signatures for understanding signature behaviour and discrepancies in gene content between them, is lacking. STUDY DESIGN, SIZE, DURATION: A multicentre prospective study was performed between July 2018 and October 2020 at five different centres from the same group of clinics (Spain). This study recruited 281 patients and finally included in the gene expression analysis 225 Caucasian patients who underwent IVF treatment. After preprocessing and batch effect filtering, gene expression measurements from 217 patients were combined with artificial intelligence algorithms (support vector machine, random forest and k-nearest neighbours) allowing evaluation of different prediction models. In addition, secretory-phase endometrial transcriptomes from gene expression omnibus (GEO) datasets were analysed for 137 women, to study the endometrial dating capacity of genes independently and grouped by signatures. This provided data on the consistency of prediction across different gene expression technologies and datasets. PARTICIPANTS/MATERIALS, SETTING, METHODS: Endometrial biopsies were analysed using a targeted TruSeq (Illumina) custom RNA expression panel called the endometrial dating panel (ED panel). This panel included 301 genes previously considered relevant for endometrial dating as well as new genes selected for their anticipated value in detecting the secretory phase. Final samples (n = 217) were divided into a training set for signature discovery and an independent testing set for evaluation of predictive performance of the new signature. In addition, secretory-phase endometrial transcriptomes from GEO were analysed for 137 women to study endometrial dating capacity of genes independently and grouped by signatures. Predictive performance among these signatures was compared according to signature gene set size. MAIN RESULTS AND THE ROLE OF CHANCE: Testing of the ED panel allowed development of a model based on a new signature of 73 genes, which we termed 'TED' and delivers an enhanced tool for the consistent dating of the secretory phase progression, especially during the mid-secretory endometrium (3-8 days after progesterone (P) administration (P + 3-P + 8) in a hormone replacement therapy cycle). This new model showed the best predictive capacity in an independent test set for staging the endometrial tissue in the secretory phase, especially in the expected window of implantation (average of 114.5 ± 7.2 h of progesterone administered; range in our patient population of 82-172 h). Published sets of genes, in current use for endometrial dating and the new TED genes, were evaluated in parallel in whole-transcriptome datasets and in the ED panel dataset. TED signature performance was consistently excellent for all datasets assessed, frequently outperforming previously published sets of genes with a smaller number of genes for dating the endometrium in the secretory phase. Thus, this optimized set exhibited prediction consistency across datasets. LARGE SCALE DATA: The data used in this study is partially available at GEO database. GEO identifiers GSE4888, GSE29981, GSE58144, GSE98386. LIMITATIONS, REASONS FOR CAUTION: Although dating the endometrial biopsy is crucial for investigating endometrial progression and the receptivity process, further studies are needed to confirm whether or not endometrial dating methods in general are clinically useful and to guide the specific use of TED in the clinical setting. WIDER IMPLICATIONS OF THE FINDINGS: Multiple gene signature combinations provide adequate endometrial dating, but their predictive performance depends on the identity of the genes included, the gene expression platform, the algorithms used and dataset characteristics. TED is a next-generation endometrial assessment tool based on gene expression for accurate endometrial progression dating especially during the mid-secretory.

RESUMO

Females live longer than males in many species, including humans, and estrogens are in part responsible for this protection against aging. We reported previously that estrogens can protect rats against oxidative stress, by inducing antioxidant and longevity-related genes. Thus, this study was aimed at confirming the ability of estrogens to upregulate antioxidant and longevity-related genes in humans. For this purpose, we selected 16 women of reproductive age (18-42 years old) undergoing a fertility treatment that includes a medically induced menopause, at the Valencian Infertility Institute. We took blood samples at each time point of the treatment (basal, induced menopause, estrogen, and estrogen plus progesterone replacement therapy). mRNA expression of antioxidant and longevity-related genes in peripheral blood mononuclear cells (PBMC) was determined by real-time reverse transcriptase-polymerase chain reaction (RT-PCR). Determination of reduced glutathione (GSH) in total blood was carried out using high-performance liquid chromatography (HPLC). As expected, we found that medically induced menopause significantly decreased sexual hormone (estrogens and progesterone) levels. It also lowered glutathione peroxidase (GPx), 16S rRNA, P21, and TERF2 mRNA expression and blood GSH levels. Estrogen replacement therapy significantly restored estrogen levels and induced mRNA expression of manganese superoxide dismutase (MnSOD), GPx, 16S rRNA, P53, P21, and TERF2 and restored blood GSH levels. Progesterone replacement therapy induced a significant increase in MnSOD, P53, sestrin 2 (SENS2), and TERF2 mRNA expression when compared to basal conditions. These findings provide evidence for estrogen beneficial effects in upregulating antioxidant and longevity-related genes in women.

RESUMO

BACKGROUND: Sleep is a significant dimension of daily life. However, only a few studies have examined the sleep quality of asthmatics in a real-world clinical settings. OBJECTIVE: This study is aimed to estimate the prevalence of sleep impairments among asthmatic patients and examine the relationship between sleep quality, asthma control, rhinitis symptoms, and sociodemographic characteristics. METHODS: The present study adopted the observational cross-sectional research design that has been designed by the Italian Respiratory Society and used valid assessments to measure the study variables. RESULTS: Data from 1150 asthmatic patients (mean age 51.01 years ± 16.03) were subjected to analysis. 58.3% of the patients had impaired sleep quality (Pittsburgh Sleep Quality Index [PSQI] total scores > 5), and their mean PSQI score was 5.68 (SD = 3.4). A significant correlation emerged between sleep quality and asthma control (p = 0.0001) and a significant albeit weak correlation emerged between PSQI total scores and Total 5 Symptoms Score (r = 0.24, p = 0.0001). Sleep quality was significantly associated health-related quality of life [HRQoL]. (r = 0.50, p < 0.001). After exclusion of patients at risk for Obstructive Sleep Apnea Syndrome (OSAS) and Gastro Esophageal Reflux Disease (GERD), the most important determinants of PSQI score were HRQoL, In the entire sample asthma control is the strongest predictor of both sleep quality and HRQoL. CONCLUSIONS: The results of this real-world study highlight the prevalence, impact and predictors of sleep disturbances in asthmatic patients and suggest the need for physicians to detect poor sleep quality.

RESUMO

Antecedentes y objetivo: Los objetivos de este estudio fueron evaluar la prevalencia de diabetes mellitus tratada farmacológicamente, analizar los patrones de prescripción de los fármacos antidiabéticos y evaluar el grado de control de la enfermedad en la provincia de Cádiz. Pacientes y métodos: Estudio observacional retrospectivo utilizando las bases de datos del Sistema Público de Salud del Servicio Andaluz de Salud entre los años 2014 a 2016, ambos inclusive. Se consideró persona adulta con diabetes tratada (PADT) aquella persona mayor de 14 años que había consumido al menos un envase de medicación del grupo A10 a lo largo de cada uno de los años correspondientes de estudio. Resultados: La prevalencia de PADT varió entre el 8,65% y el 8,83% de 2014 a 2016, respectivamente. Un 71% de PADT estaban tratadas solo con fármacos no insulínicos, un 11% con insulinas y un 18% con una combinación de ambos. En aproximadamente un tercio de las PADT no se había realizado una determinación de HbA1c a lo largo de cada año. El 69% de las PADT evaluadas tenía en 2016 un adecuado grado de control de acuerdo a los criterios de la RedGDPS (según HbA1c y edad). Conclusión: La prevalencia de diabetes tratada farmacológicamente en la provincia de Cádiz es elevada y parece ir en aumento. Los pacientes presentan un limitado control glucémico, al que puede contribuir de forma predominante el seguimiento inadecuado en casi una tercera parte de los mismos


Background and objective: The aim of the study was to assess the prevalence of diabetes mellitus treated pharmacologically, analyse the prescription patterns of antidiabetic drugs and assess the degree of control over the disease in the province of Cadiz. Patients and methods: An observational retrospective study was conducted with the databases of the public health system of the Andalusian Health Service between 2014 and 2016, inclusive. Adults with treated diabetes (ATD) were considered those older than 14 years who had consumed at least 1 package of medication from the A10 group during the corresponding year covered by the study. Results: The prevalence of ATD varied between 8.65% and 8.83% from 2014 to 2016, respectively. Seventy-one percent of the ATD were treated with only noninsulin drugs, 11% were treated with insulin, and 18% were treated with a combination of both. For approximately one-third of the ATD, an HbA1c reading was not performed during each year. Sixty-nine percent of the assessed ATD in 2016 had an appropriate degree of control according to RedGDPS criteria (based on HbA1c and age). Conclusion: The prevalence of pharmacologically treated diabetes in the province of Cadiz is high and appears to be increasing. The patients presented limited glycaemic control, to which inadequate follow-up in almost a third of the patients could be the major contributor

RESUMO

Nasal cytology is an easy, cheap, non-invasive and point-of-care method to assess nasal inflammation and disease-specific cellular features. By means of nasal cytology, it is possible to distinguish between different inflammatory patterns that are typically associated with specific diseases (ie, allergic and non-allergic rhinitis). Its use is particularly relevant when other clinical information, such as signs, symptoms, time-course and allergic sensitizations, is not enough to recognize which of the different rhinitis phenotypes is involved; for example, it is only by means of nasal cytology that it is possible to distinguish, among the non-allergic rhinitis, those characterized by eosinophilic (NARES), mast cellular (NARMA), mixed eosinophilic-mast cellular (NARESMA) or neutrophilic (NARNE) inflammation. Despite its clinical usefulness, cheapness, non-invasiveness and easiness, nasal cytology is still underused and this is at least partially due to the fact that, as far as now, there is not a consensus or an official recommendation on its methodological issues. We here review the scientific literature about nasal cytology, giving recommendations on how to perform and interpret nasal cytology.

RESUMO

The effect of the fungicide tebuconazole (0.41, 0.52, 0.71 and 1.14mg/L) on survival, reproduction and growth of Daphnia magna organisms was monitored using 14 and 21 days exposure tests. A third experiment was performed by exposing D. magna to the fungicide for 14 days followed by 7 days of recovery (14+7). In order to test fungicide effects on D. magna, parameters as survival, mean whole body length, mean total number of neonates per female, mean number of broods per female, mean brood size per female, time to first brood/reproduction and intrinsic rate of natural increase (r) were used. Reproduction was seriously affected by tebuconazole. All tebuconazole concentrations tested affected the number of broods per female and day to first brood. At 14-days test, number of neonates per female and body size decreased by concentrations of tebuconazole higher than 0.52mg/L, whereas at 21-days test both parameters were affected at all the concentrations tested. Survival of the daphnids after 14 days fungicide exposure did not exhibited differences among experimental and control groups. In this experiment r value was reduced (in a 22%) when animals were exposed to concentrations of 0.71mg/L and 1.14mg/L. Survival of daphnids exposed during 21 days to 1.14mg/L declined, and the intrinsic rate of natural increase (r) decreased in a 30 % for tebuconazole concentrations higher than 0.41mg/L. Longevity of daphnids pre-exposed to tebuconazole for 14 days and 7 days in clean water did not show differences from control values and all of them survived the 21 days of the test. However, after 7 days in fungicide free medium animals were unable to restore control values for reproductive parameters and length. The maximum acceptable toxicant concentration (MATC) was calculated using the r values as parameter of evaluation. MATC estimations were 0.61mg/L and 0.46mg/L for 14 and 21 days, respectively. Results showed that the number of neonates per female was the highest sensitive parameter to the effects of tebuconazole on D. magna. On the other hand, a recovery period of 7 days in a free toxicant medium would not be longer enough to reestablish normal reproduction parameters in pre-exposed tebuconazole daphnids.

RESUMO

Thiobencarb and propanil are two of the most extensive used herbicides worldwide in rice cultivation. Especially scanty is the available information regarding the effect of herbicides on fish energy resources. In the present study, the effect of sublethal exposure to these herbicides on the energy reserves of juvenile eel Anguilla anguilla was compared. Eels were exposed to 72 h to the herbicide thiobencarb (0.22 mg L(-1)) or Propanil (0.63 mg L(-1)), and allowed to recover in clean water (144 h). Caloric content was determined in liver and skeletal muscle. Fish exposed to thiobencarb rapidly mobilized energy. Reserves from liver were depleted (21%) compared to control values (2.50 kcal g(-1)) at 2 h, whereas in muscle diminished between 12 and 72 h (35%) (control value 0.89 kcal g(-1)). Energy reserves from liver normalized after 144 h in water while in the skeletal muscle were still depleted (24%). Major harmful effects were induced by propanil. Caloric content in liver diminished from the first hours (depletion of 70% at 48h exposure) and in skeletal muscle a 60% (72 h). At the end of the recovery period, energy reserves in pre-exposed eels represented less than 50% compared to control animals. The study indicated that thiobencarb and propanil would constitute a great risk to animals inhabiting freshwater bodies nearby fields of application. Judging from the results, herbicides resulted toxic enough to mobilize fish energy stores. On the other hand, a period of six days in herbicide-free water was not enough time to allow fish to restore energy budgets.

RESUMO

Acupuncture has been proven to be effective in the treatment of various cardiovascular disorders; it acts both on the peripheral flow and on the cerebral flow. Our study aimed to evaluate the effects of the insertion of PC 6 Neiguan and LR 3 Taichong acupoints on the cerebral blood flow (CBF) in the middle cerebral artery (MCA). These effects were measured in a group of patients suffering from migraine without aura (Group M) and in a healthy control group (Group C). In the study, we included 16 patients suffering from migraine without aura, classified according to the criteria of the International Headache Society, and 14 healthy subjects as a control group. The subjects took part in the study on two different days, and on each day, the effect of a single acupoint was evaluated. Transcranial Doppler was used to measure the blood flow velocity (BFV) in the MCA. Our study showed that the stimulation of PC 6 Neiguan in both groups results in a significant and longlasting reduction in the average BFV in the MCA. After pricking LR 3 Taichong, instead, the average BFV undergoes a very sudden and marked increase; subsequently, it decreases and tends to stabilize at a slightly higher level compared with the baseline, recorded before needle insertion. Our data seem to suggest that these two acupoints have very different effects on CBF. The insertion of PC 6 Neiguan probably triggers a vasodilation in MCA, while the pricking of LR 3 Taichong determines a rapid and marked vasoconstriction.

RESUMO

Streptococcus suis is a major bacterial pathogen of young pigs causing worldwide economic problems for the pig industry. S. suis is also an emerging pathogen of humans. Colonization of porcine oropharynx by S. suis is considered to be a high risk factor for invasive disease. In the oropharyngeal cavity, where glucose is rapidly absorbed but dietary α-glucans persist, there is a profound effect of carbohydrate availability on the expression of virulence genes. Nineteen predicted or confirmed S. suis virulence genes that promote adhesion to and invasion of epithelial cells were expressed at higher levels when S. suis was supplied with the α-glucan starch/pullulan compared to glucose as the single carbon source. Additionally the production of suilysin, a toxin that damages epithelial cells, was increased more than ten-fold when glucose levels were low and S. suis was growing on pullulan. Based on biochemical, bioinformatics and in vitro and in vivo gene expression studies, we developed a biological model that postulates the effect of carbon catabolite repression on expression of virulence genes in the mucosa, organs and blood. This research increases our understanding of S. suis virulence mechanisms and has important implications for the design of future control strategies including the development of anti-infective strategies by modulating animal feed composition.

RESUMO

The present study investigates energy stores changes in the aquatic invertebrate Daphnia magna following a 5-d exposure to propanil. Juveniles of D. magna were exposed to sublethal propanil concentrations (0.07, 0.10, 0.21 and 0.55 mgl(-1)) which were used previously to test their effect on reproduction, growth and survival (21 days test) of D. magna. Glycogen, total lipids, proteins, and dry weight were determined in control and exposed daphnids at 24, 48, 72, 96 and 120 h. Data were used to calculate caloric content as biomarker of propanil exposure. Results showed a depletion of energy reserves in D. magna exposed to the herbicide. At 120 h of exposure to the highest propanil concentration (0.5 mgl(-1)), the reduction in daphnid reserves were glycogen (28%), proteins (28%) and lipids (31%), and caloric content was reduced in 27%. On the other hand, we found a positive correlation between caloric content and the chronic parameters intrinsic rate of natural increase and offspring per female when daphnids were exposed for 120 h to the herbicide.

RESUMO

Implantación en un centro de salud de una herramienta informática con el objetivo de facilitar el control de caducidades y garantizar la adecuada trazabilidad de los medicamentos existentes en los botiquines. El proceso se inicia con el registro de entrada de los medicamentos (marca y principio activo), lotes, caducidades y cantidad en la aplicación informática, y al final de cada mes se imprime el informe de caducidades por lotes procediendo a su retirada del botiquín. El programa también permite obtener un informe con los lotes de los medicamentos almacenados permitiendo su rápida localización y retirada en caso de alerta farmacéutica de la Agencia Española de Medicamentos y Productos Sanitarios. El nuevo sistema agiliza y mejora el control y retirada de los medicamentos ya que ahora se revisan lotes y no unidades de ampollas o comprimidos. Ante los buenos resultados obtenidos, se procederá en los próximos meses a su implantación en el resto de centro de salud del Distrito, mediante formación dirigida a los responsables de botiquines (AU)


Deployment Health Center (CS) of a tool, in order to facilitate monitoring of expiry dates and ensure proper tracking of existing drugs in the medicine chest. The process begins with check of drugs (brand and active), batch, expiry dates and quantity in the software, and end of each month to print the batch report forfeitures to the removal of the medicine chest. The program also allows for a report with lots of drugs stored enabling the rapid location and retrieval in the event of drug alert from the Spanish Agency of Medicines and Health Products (Competent Authority). The new system streamlines and improves the control and removal of drugs and lots now reviewed and no blisters or compressed drives. Given the good results obtained, we proceed in the coming months to its implementation in the rest of CS District by training for those responsible for first aid kits (AU)

RESUMO

Prostate cancer (PCa) is the second leading cause of cancer-associated death in men. Once a tumor is established it may attain further characteristics via mutations or hypoxia, which stimulate new blood vessels. Angiogenesis is a hallmark in the pathogenesis of cancer and inflammatory diseases that may predispose to cancer. Heme oxygenase-1 (HO-1) counteracts oxidative and inflammatory damage and was previously reported to play a key role in prostate carcinogenesis. To gain insight into the anti-tumoral properties of HO-1, we investigated its capability to modulate PCa associated-angiogenesis. In the present study, we identified in PC3 cells a set of inflammatory and pro-angiogenic genes down-regulated in response to HO-1 overexpression, in particular VEGFA, VEGFC, HIF1α and α5ß1 integrin. Our results indicated that HO-1 counteracts oxidative imbalance reducing ROS levels. An in vivo angiogenic assay showed that intradermal inoculation of PC3 cells stable transfected with HO-1 (PC3HO-1) generated tumours less vascularised than controls, with decreased microvessel density and reduced CD34 and MMP9 positive staining. Interestingly, longer term grown PC3HO-1 xenografts displayed reduced neovascularization with the subsequent down-regulation of VEGFR2 expression. Additionally, HO-1 repressed nuclear factor κB (NF-κB)-mediated transcription from an NF-κB responsive luciferase reporter construct, which strongly suggests that HO-1 may regulate angiogenesis through this pathway. Taken together, these data supports a key role of HO-1 as a modulator of the angiogenic switch in prostate carcinogenesis ascertaining it as a logical target for intervention therapy.

RESUMO

Objetivo: Implantar un programa de revisión sistemática de prescripciones electrónicas para potenciar el uso seguro y eficiente de los medicamentos. Material y método: Proyecto que comenzó en mayo de 2010 en un distrito sanitario de Atención Primaria que da cobertura a medio millón de habitantes aproximadamente. Consiste en la revisión y seguimiento estrecho de las prescripciones electrónicas por los médicos de familia. En esta revisión se incluyó a todos los pacientes con prescripciones electrónicas, priorizando a aquellos polimedicados. Este programa, que desde su implantación fue considerado como punto crítico para mejorar el uso de los medicamentos, fue diseñado e impulsado por la Dirección del Distrito y el Servicio de Farmacia, y contó con el seguimiento de los directores de cada centro de salud. Para dimensionar su impacto, se analizaron como indicadores de seguimiento: el importe/TAFE estimado anual y el número de recetas/TAFE estimado anual. La TAFE es la tarjeta sanitaria ponderada según la edad del usuario y su peso en farmacia asociado. Resultados: El objetivo del proyecto se ha alcanzado con éxito, lo que se ha visto reflejado en el elevado número de pacientes revisados, la disminución del número de recetas estimadas anuales y por tanto, del importe generado por ellas. Conclusión: La receta electrónica es una herramienta importante para conseguir una gestión más eficiente de las consultas médicas, pero la falta de seguimiento por parte de los médicos de los tratamientos prescritos durante períodos prolongados conduce a una utilización inadecuada de los recursos terapéuticos, que es necesario abordar con estrategias como la realizada (AU)


Objective: To implement a systematic review of electronic prescriptions with a view to promoting the safe and efficient use of drugs. Materials and method: This scheme was introduced in May 2010 in a Primary Healthcare District serving a population of approximately half a million inhabitants, and involved the analysis and close monitoring of the electronic prescriptions generated by general practitioners. All patients receiving electronic prescriptions were included in the study, and priority was given to patients on multiple medication. From its very inception the project was considered crucial to improving the safe and efficient use of prescription drugs, and was designed and promoted by the Directors of the Primary Healthcare District and by the members of its Pharmacy Department, with monitoring provided by the Directors of each Primary Healthcare Centre. To measure its impact, we employed the following as monitoring indicators: estimated annual cost/TAFE and estimated annual number of prescriptions/TAFE. TAFE relates to the individual healthcare card weighted in accordance with the age of the user and his or her related pharmaceutical cost. Results: The original aim was successfully achieved, and is reflected in the large number of patients reviewed, in a decrease in the estimated annual number of prescriptions, and, consequently, in the corresponding pharmaceutical cost. Conclusion: Electronic prescribing is an important tool in developing more effective management of the general practitioner clinic, but failure by the physician to monitor prescribed treatments over prolonged periods leads to the inappropriate use of therapeutic resources and, to avoid this, it is essential to implement strategies such as the one described (AU)
