A randomized clinical trial comparing the efficacy of lidocaine administered intravenously, intranasally or as infraorbital nerve block in dogs undergoing rostral rhinosocopy.

OBJECTIVE: To compare the efficacy of lidocaine administered intravenously, intranasally or as an infraorbital nerve block in dogs undergoing rostral rhinoscopy. STUDY DESIGN: Randomized clinical trial. ANIMALS: A total of 43 client-owned dogs. METHODS: After premedication with medetomidine 0.01 mg kg-1 and methadone 0.2 mg kg-1 intramuscularly, anaesthesia was induced with propofol and maintained with isoflurane in oxygen. Dogs were randomly allocated to receive 2 mg kg-1 of 2% lidocaine as a bilateral infraorbital nerve block (INB) via the caudal intraoral approach, via bilateral topical intranasal administration (TIA) or as an intravenous bolus (IVB). At 5 minutes following lidocaine administration, responses to rhinoscopy (RR) and biopsies (RB) were evaluated using a simple scoring system (0: no reaction; 1: reaction). Response to the rhinoscopy in the recovery period (RE) was recorded. Recovery quality was scored using a simple descriptive score. Heart rate, respiratory rate and noninvasive arterial blood pressure were recorded. Intravenous (IV) fentanyl 0.001 mg kg-1 was administered if an increase > 20% in any variable occurred. Gross movement was attenuated using propofol 0.5 mg kg-1 IV. Scores were analysed using the Chi-square test with Monte Carlo method. Cardiorespiratory changes among and overtime between groups were compared using one-way anova and one-way anova for repeated measures, respectively, or the correspondent non-parametric tests; p < 0.05. RESULT: Of the 43 dogs, 42 completed the study. No statistically significant differences were detected in either physical reactions or changes in cardiorespiratory variables for RR, RB, RE or recovery quality, although RB tended to be higher in group TIA (7/10 versus 1/10 INB and 3/13 IVB).Various cardiorespiratory variables changed overtime within groups. CONCLUSIONS AND CLINICAL RELEVANCE: In dogs, all three investigated techniques attenuated responses during rostral rhinoscopy in dogs, although INB and IVB were more efficacious when biopsies were taken.

Efficacy and safety of cold versus hot snare polypectomy for small (5-9 mm) colorectal polyps: a multicenter randomized controlled trial.

BACKGROUND: Resection techniques for small polyps include cold snare polypectomy (CSP) and hot snare polypectomy (HSP). This study compared CSP and HSP in 5-9 mm polyps in terms of complete resection and adverse events. METHODS: This was a multicenter, randomized trial conducted in seven Spanish centers between February and November 2019. Patients with ≥ 1 5-9 mm polyp were randomized to CSP or HSP, regardless of morphology or pit pattern. After polypectomy, two marginal biopsies were submitted to a pathologist who was blinded to polyp histology. Complete resection was defined as normal mucosa or burn artifacts in the biopsies. Abdominal pain was only assessed in patients without < 5 mm or > 9 mm polyps. RESULTS: 496 patients were randomized: 237 (394 polyps) to CSP and 259 (397 polyps) to HSP. Complete polypectomy rates were 92.5 % with CSP and 94.0 % with HSP (difference 1.5 %, 95 % confidence interval -1.9 % to 4.9 %). Intraprocedural bleeding occurred during three CSPs (0.8 %) and seven HSPs (1.8 %) (P = 0.34). One lesion per group (0.4 %) presented delayed hemorrhage. Post-colonoscopy abdominal pain presented similarly in both groups 1 hour after the procedure (CSP 18.8 % vs. HSP 18.4 %) but was higher in the HSP group after 5 hours (5.9 % vs. 16.5 %; P = 0.02). A higher proportion of patients were asymptomatic 24 hours after CSP than after HSP (97 % vs. 86.4 %; P = 0.01). CONCLUSIONS: We observed no differences in complete resection and bleeding rates between CSP and HSP. CSP reduced the intensity and duration of post-colonoscopy abdominal pain.

IMMOBILIZATION OF MOUFLON (OVIS ORIENTALIS MUSIMON) USING MEDETOMIDINE-KETAMINE-MORPHINE OR DEXMEDETOMIDINE-KETAMINE-MORPHINE.

This study is aimed at evaluating the efficacy of two protocols for the immobilization of mouflon (Ovis orientalis musimon). Six mouflon were immobilized twice using IM medetomidine 0.07 ± 0.01 mg/kg, ketamine 2.88 ± 0.48 mg/kg, and morphine 0.57 ± 0.09 mg/kg (MKM) or dexmedetomidine 0.04 ± 0.01 mg/kg, ketamine 3.01 ± 0.6 mg/kg, and morphine 0.60 ± 0.12 mg/kg (DKM). Anesthetic times were recorded from injection to initial drug effects, sternal recumbency, lateral recumbency, unresponsiveness to external stimuli, and recovery following atipamezole IM administration. Cardiopulmonary variables (HR in beats/min, RR in breaths/min, mean, systolic, and diastolic noninvasive blood pressure [MAP, SAP, DAP] in mm Hg, oxygen hemoglobin saturation [SpO2)], expired end tidal carbon dioxide [PECO2]), and rectal temperature in °C were monitored and recorded. No statistically significant differences were detected between protocols at any time point and no significant differences were detected in any measured variables at any time point between protocols. However, a significant decrease in the noninvasive blood pressure variables (SAP, MAP, and DAP) and in the RR were detected over time. Both chemical immobilization protocols provided at least 50 min of immobilization in mouflon, allowing minor procedures and tracheal intubation.

[Compliance with process indicators in people with type 2 diabetes and linking incentives in Primary Care]. / Cumplimiento de indicadores de proceso en personas con diabetes tipo 2 y la vinculación a incentivos en Atención Primaria.

OBJECTIVE: Pay-for-performance programs to improve the quality of health care are extending gradually, particularly en Primary Health Care. Our aim was to explore the relationship between the degree of compliance with the process indicators (PrI) of type 2 diabetes (T2DM) in Primary Care and linkage to incentives. DESIGN: Cross-sectional, descriptive, observational study. SETTING: Six Primary Health Care centers in Seville Aljarafe District randomly selected and stratified by population size. PARTICIPANTS: From 3.647 adults included in Integrated Healthcare Process of T2DM during 2008, 366 patients were included according sample size calculation by stratified random sampling. MEASUREMENTS: PrI: eye and feet examination, glycated hemoglobin, lipid profile, microalbuminuria and electrocardiogram. Confounding: Age, gender, characteristics town for patients and professional variables. RESULTS: The mean age was 66.36 years (standard deviation [DE]: 11,56); 48.9% were women. PrI with better compliance were feet examination, glycated hemoglobin and lipid profile (59.6%, 44.3% and 44%, respectively). 2.7% of patients had simultaneous compliance of the six PrI and 11.74% of patients three PrI linkage to incentives. Statistical association was observed in the compliance of the PrI incentives linked or not (P=.001). CONCLUSIONS: The degree of compliance with the PrI for screening chronic complications of T2DM is mostly low but this was higher on indicators linked to incentives.

Violence Exposure and Disability in Colombian Female Survivors of Intimate Partner Violence: the Mediating Role of Depressive Symptoms.

BACKGROUND: Violence is an important public health problem and one of the main causes of deaths worldwide. The mental health consequences of surviving intimate partner violence (IPV) include depression, anxiety and post-traumatic stress disorder. Previous studies have identified that there is a relationship between depression and level of disability in female survivors of IPV. Estimating the direct, indirect or total effect of an exposure on an outcome makes it possible to identify mediating effects between a group of variables. Detecting mediation effects is useful for identifying casual pathways that generate a final outcome and provides a rationale for designing interventions to target the mediator, which in turn positively affects the outcome. The objective was to identify the mediating role of depressive symptoms on the relationship between IPV and disability. METHODS: This was a cross-sectional study of 94 women over the age of 18 who were survivors of IPV by men. They were recruited from two public hospitals in Cali and Tuluá in southwest Colombia. An analysis of casual relationships was performed using structural equation modelling that was made up of: four exogenous observed variables (age, current relationship status [in a relationship or single], level of schooling, and history of an impairment), intermediate endogenous variables (violence and depressive symptoms), and the main endogenous variable (disability). The analyses were carried out in Stata14.2. RESULTS: The direct effect of IPV severity on the level of disability was not statistically significant (ß=0.09; P=0.63). However, the indirect effect of IPV severity on disability mediated by depressive symptoms was (ß=0.39; P<0.01). The total effect of IPV severity on the level of disability was even greater (ß=0.48; P=0.01). CONCLUSIONS: This study found a complete mediating role of depressive symptoms on the relationship between the severity of IPV and the level of disability for the female participants in this study. The results of this research contribute to defining strategies to prevent and address intimate partner violence, depressive symptoms and disability in this population.

Giant hiatal hernia with intrathoracic spleen: A case report.

Hiatal hernia is a frequent pathology in the population; however, the most frequent hiatal hernia is type I, which accounts for up to 95% incidence, types II, III, and IV being less frequent and representing between 5% and 15%, and even less common are giant hernias. The definition of the giant hernia is still not exact in the literature; some authors define giant or massive hiatal hernia as one in which the hernia occupies more than 30% of the stomach and/or passes from other abdominal structures to the thorax. We describe the case of a patient with gastrointestinal symptomology without response to a proton pump inhibitor, with base exacerbation that required imaging studies, showing a large hernia defect passing to the thorax from abdominal organs (stomach, spleen, mesenteric fat), as well as alteration of the gastric and spleen axis with ascent in pancreatic body and tail, which corresponds to a giant hiatal hernia. Said pathology is very infrequent, with recurrences and postoperative complications. Our patient recovered from the surgical procedure with therapeutic success.

Reversed priapism, thrombosis of the dorsal penile vein: A case report.

Priapism is an unintentional prolonged penile erection, lasting equal to or greater than 4 hours, in the absence of sexual stimulation or after having finished it. It is a rare pathology that can represent a urological emergency. The present report describes the case of a 25-year-old patient who presented priapism after suffering a one-meter fall on the genital area. Patient is a 25-year-old male with macroscopic hematuria without clots, testicular pain 4/10 on the numerical pain scale, stabbing type, without irradiation, secondary to a fall that occurred 3 months earlier, which resulted in a blow to the genital area. He presented an evolution of 20 days with detumescence and erectile dysfunction. Penile Doppler was performed and inverted priapism, arteriolacunar fistula at the base of the left corpus cavernosum, plus severe erectile dysfunction, were diagnosed. After a cavernography and an arteriography, a thrombolysis was performed. The patient continued with anticoagulant treatment with clopidogrel and enoxaparin and did not present complications after thrombolysis. A detailed clinical history, physical examination and a Doppler ultrasound study can provide a clear and timely diagnosis for the patient. Cavernography and arteriography have shown satisfactory results. In the present case, thrombolysis treatment with alteplase provided favorable results.

The Mechanical Performance of Recycled Slate Waste Fiber Composites Based on Unsaturated Polyester Resins.

In the last few decades, there has been increasing social awareness for environmental conservation, which is driving the development of composite materials based on natural fibers. These new materials have interesting properties that allow for their use in a variety of applications. This study deals with the development of composite materials based on unsaturated polyester resins reinforced with recycled mineral fibers, such as slate fibers obtained from slate production waste, which have similar properties to glass fiber. The mechanical properties of these composites have been determined by tensile and flexural/bending tests. The influence of various variables such as matrix composition (flexible polyester content) and the weight percentage of fiber added to mechanical properties were evaluated. The flexible/rigid polyester content varied from 0 to 40% and the fiber one from 0 to 30 wt%. Composites with ≥20 wt% of slate fiber reinforcement are shown to have tensile (35 MPa) and flexural (57 MPa) strengths that can compete with materials reinforced with artificial fibers.

Quality of life in Spanish postmenopausal breast cancer patients with localized disease who finish endocrine treatment: a prospective study.

OBJECTIVE: In this article, the quality of life (QOL) of Spanish postmenopausal early-stage breast cancer patients who have finished endocrine therapy (ET), QOL changes after endocrine therapy cessation, and the differences between two endocrine therapy modalities (tamoxifen or aromatase inhibitor [AI]) are studied. More QOL information after endocrine therapy cessation is needed. METHODS: A prospective cohort study was performed. Participating in the study were 158 postmenopausal patients who had received tamoxifen or AI for 5 years. In some cases, endocrine therapy may have changed during those 5 years.Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR45 questionnaires at baseline, after 6 months, and after 1 year of follow-up. Patients older than 65 years also completed the QLQ-ELD14. Linear mixed-effect models were used to evaluate longitudinal changes in QOL and differences in QOL between endocrine therapy modalities. RESULTS: QOL scores for the whole sample throughout follow-up were high (>80/100 points) in most QOL areas. Moderate limitations (>30 points) occurred in the QLQ-BR45 in sexual functioning and sexual enjoyment, future perspective, and joint symptoms. Moderate limitations also occurred in the QLQ-ELD14 in worries about others, maintaining purpose, joint stiffness, future worries, and family support. In those who had finished endocrine therapy, pain was reduced in all three assessments conducted during the 1-year follow-up period in both groups. Tamoxifen patients showed better QOL in functioning (role functioning, global QOL, financial impact), symptoms (pain), and emotional areas (future perspective and worries about others) than AI patients but worse QOL in skin mucosis symptoms. CONCLUSIONS: The results of this study show that postmenopausal early-stage breast cancer patients adapted well to their disease and endocrine therapy treatment. QOL improvements in the 1-year follow-up period appeared in one key area: pain. Differences between endocrine therapy modalities suggested QOL was better in the tamoxifen group than in the AI group.

Seasonal and Temporal Patterns of Homicides and Suicides in Cali and Manizales, Colombia: A Times-Series Analysis 2008-2015.

OBJECTIVE: To identify seasonal and temporal variations in daily incidence of homicides and suicides in Cali and Manizales, Colombia during 2008-2015. MATERIALS AND METHODS: An ecological time series study was performed using negative binomial regression models for daily incidence of homicides and suicides; analyses were controlled for yearly trends and temporal autocorrelations. RESULTS: Saturdays, Sundays, December holidays as well as New Year and New Year's Eve were associated with an increased risk of homicides in both cities. Suicide risk increased during December holidays and New Year in both cities. In addition, the suicide risk increased on paydays, Saturdays, Sundays, and Mondays in Cali, and it decreased during the Holy Week holidays in Manizales. December patterns of suicides and homicides are the opposite in each city, and between cities. CONCLUSIONS: The incidences of homicides and suicides are not homogeneous over time. These patterns can be explained partially by alcohol consumption and changes in people's routine activities which may modify exposure to violent circumstances.

The coexistence of diabetic retinopathy and diabetic nephropathy is associated with worse kidney outcomes.

Background: Up to 50-60% of patients with diabetes have non-diabetic kidney disease (NDKD) on kidney biopsy. Diabetic retinopathy (DR) is a microvascular complication of diabetes frequently associated with diabetic nephropathy (DN). The objective of the current study was to investigate the kidney outcomes and survival in patients with biopsy diagnoses of DN and NDKD according to the presence of DR. Methods: We conducted an observational, multicentre and retrospective study of the pathological findings of renal biopsies from 832 consecutive patients with diabetes from 2002 to 2014 from 18 nephrology departments. The association of DR with kidney replacement therapy (KRT) or survival was assessed by Kaplan-Meier and Cox regression analyses. Results: Of 832 patients with diabetes and renal biopsy, 768 had a retinal examination and 221/768 (22.6%) had DR. During a follow-up of 10 years, 288/760 (37.9%) patients with follow-up data needed KRT and 157/760 (20.7%) died. The incidence of KRT was higher among patients with DN (alone or with NDKD) and DR [103/175 (58.9%)] than among patients without DR [88/216 (40.7%), P < .0001]. The incidence of KRT was also higher among patients with only NDKD and DR than among those without DR [18/46 (39.1%) versus 79/331 (23.9%), P < .0001]. In multivariate analysis, DR or DN were independent risk factors for KRT {hazard ratio [HR] 2.48 [confidence interval (CI) 1.85-3.31], P < .001}. DN (with or without DR) was also identified as an independent risk factor for mortality [HR 1.81 (CI 1.26-2.62), P = .001]. Conclusions: DR is associated with a higher risk of progression to kidney failure in patients with histological DN and in patients with NDKD.

[System of comparable indicators for peaceful coexistence and citizen security: a consensus among countries]. / Sistema de indicadores comparables de convivencia y seguridad ciudadana: un consenso de países.

The Region of the Americas, with a homicide rate of 16.4 per 100,000 population (2004), is the second most violent region in the world, but public policy-making for the prevention of violence and crime is hampered by the absence of reliable and comparable data on the problem's various manifestations. This paper describes a 14-country initiative, sponsored by the Inter-American Development Bank in partnership with other regional agencies, to develop-collectively and by consensus- indicators for peaceful coexistence and citizen security that permit comparisons among countries, systematization of methods for the production and collection of pertinent data, the development of regional policies, and the dissemination and sharing of good practices. The selected indicators were homicide, death from road traffic injuries, suicide, death by firearm, sexual crime, family violence, child abuse, robbery, theft, vehicle theft and robbery, abduction, traffic offenses committed while under the influence of alcohol, general victimization, victimization by theft, victimization by robbery, perception of insecurity, perception of fear, confidence in institutions, and justification of the use of violence. For each indicator, agreement was reached on the type of measurement and the minimum variables that should be taken into account to have appropriate criteria for comparison.

Plasma Nickel Levels Correlate with Low Muscular Strength and Renal Function Parameters in Patients with Prostate Cancer.

Nickel is associated with cancer in occupational exposure. However, few studies have been devoted to analyzing the effects of nickel at environmental concentrations in cancer patients. In this work, the concentration of nickel in blood samples from patients with prostate cancer (PCa) was evaluated because this metal displays androgenic and estrogenic effects that play a crucial role in prostate carcinogenesis and treatment. We, therefore, compared blood nickel concentration in patients with PCa (non-occupationally exposed) (n = 46) with those in control age-matched individuals (n = 46). We also analyzed if there was any association between sociodemographic factors, clinical variables, geriatric evaluation assessment results, blood cell counts, or biochemical, androgen and estrogen concentrations. Using inductively coupled plasma-mass spectroscopy on the plasma samples, we observed a mean nickel level of 4.97 ± 1.20 µg/L in the PCa group and 3.59 ± 0.49 µg/L in the control group, with a non-significant effect (p = 0.293) between the two groups. The nickel concentration was significantly correlated with patient age (p = 0.005) and reduced handgrip strength (p = 0.003). Regarding biochemical parameters, significant associations were found with the renal glomerular filtration rate (p = 0.024) and blood urea levels (p = 0.016). No significant correlations were observed with other blood analytical parameters or testosterone or estradiol levels. These specific renal function and muscle strength effects were observed at environmental nickel exposure levels believed to be safe or at least far from the high concentrations observed after occupational exposure. Therefore, these parameters deserve further study, given that they could help pinpoint further public health concerns regarding nickel exposure in the general population.

Performance of a Likert adaptation of the SRQ-20 scale among women victims of intimate partner violence in Colombia: an exploratory study.

Women who are victims of intimate partner violence often suffer of depression and anxiety disorders. We evaluated the performance of the SRQ-20 scale (screening test for common mental health disorders), in women victims of intimate partner violence by male partners. A total of 100 women were surveyed from the out-patient mental health services in four health institutions in Valle del Cauca (Colombia). SRQ-20 scales (Binary version versus Likert version) were compared with mental health diagnoses based on the HSCL-25 scale, as the gold standard. Optimal SRQ-20 cut-off score is > = 6 points; lower than the initially suggested, sensitivity of 96.6% and specificity of 90.9%. The new SRQ-20-Likert scale, establishing a cut-off of > = 8 points, shows better sensitivity (98.9%) and equal specificity than the original scale. Studied SRQ-20 scales are promising instruments for screening mental health disorders among women victims of intimate partner violence in primary health care settings.

Becoming baby-friendly in Spain: a quality-improvement process.

AIM: To describe the implementation process and effect of a quality-improvement intervention aimed at achieving compliance with the Baby-friendly Hospital Initiative (BFHI). METHODS: We conducted a prospective study of the development and evaluation of a quality-improvement intervention at the Yecla Hospital, Spain. A random sample of 1273 infants born in the hospital was followed up in primary care centres between 1997 and 2005. The study interventions were process-oriented training, audit and feedback, quality-improvement cycles and provision of breastfeeding support resources. The main outcome measures were changes in compliance with the Global Criteria for the BFHI and breastfeeding rates before, during and after the intervention. RESULTS: Compliance with the Global Criteria increased progressively, and in 2004 all criteria were met. The median duration of breastfeeding went up gradually from the start of the intervention. The likelihood of being breastfed at different ages among infants born in 2005 was between 45% [odds ratio (OR) 0.55; 95% confidence interval (CI) 0.38-0.79] and 86% (OR 0.14; 95% CI 0.09-0.20) higher than among infants born in 1997. CONCLUSION: Quality-improvement interventions based on participation, training, audit and feedback of information, and provision of resources are useful for the implementation of the BFHI, which is associated with a significant increase in breastfeeding rates.

Potential of Industrial Pineapple (Ananas comosus (L.) Merrill) By-Products as Aromatic and Antioxidant Sources.

Pineapple is meanly commercially processed. However, it is a fruit that generates a high proportion of nonedible wastes, which are rich in antioxidant compounds and have a varied aromatic profile. These characteristics turn these by-products into potential agri-food waste that can be revalued and applied in different fields such as medical, pharmaceutical, or food applications. The aim of the present work was the characterization and extraction of the volatile compounds present in two pineapple by-products (peel and core) and the subsequent evaluation of their antioxidant capacity. For this purpose, the analysis of the aromatic profile of both by-products has been carried out using the headspace solid-phase microextraction technique coupled to gas chromatography with a mass spectrometry detector (HS-SPME-GC-MS). The optimization of the extraction conditions of the volatile compounds has been validated using a Box-Behnken experimental design. In addition, a quantitative analysis was carried out to determine the contents of two important volatiles in pineapple wastes, isopentyl, and ethyl acetate. Moreover, the estimation of the antioxidant capacity of the subproducts extracts was carried out using different methods All the antioxidant assays demonstrated that pineapple subproducts are rich in easily extractable antioxidants with possible applications in the food industry.

Optimization of Volatile Compounds Extraction from Industrial Celery (Apium graveolens) By-Products by Using Response Surface Methodology and Study of Their Potential as Antioxidant Sources.

In this study, the potential of industrial celery by-products (the stalk and root) serving as sources of aromatics and antioxidants was investigated. A headspace solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) procedure was optimized to isolate volatile compounds from celery by-products. A Box-Behnken experimental design was proposed to optimize the procedure through a response surface methodology. The optimal extraction conditions were found to be 1.6 g of homogenized fresh by-product at 30 °C for 60 min. Under these conditions, 26 volatile compounds in stalk and root samples were identified, monoterpenes and sesquiterpenes being the main components. The content of limonene and γ-terpinene found in the stalk was significantly higher in comparison with root samples. Total phenolic content and antioxidant activity (ABTS and FRAP) results underlined the celery wastes studied as good sources of free radical scavengers. This work suggests the potential application of these by-products in the food industry and opens new pathways to valorize celery residues, contributing to the circular economy.

Prenatal exposure to phthalates and its effects upon cognitive and motor functions: A systematic review.

Phthalates are chemicals widely used in packaging and consumer products, which have been shown to interfere with normal hormonal function and development in some human and animal studies. In recent decades, pregnant women's exposure to phthalates has been shown to alter the cognitive outcomes of their babies, and some studies have found delays in motor development. METHODS: electronic databases including PubMed/MEDLINE and Scopus were searched from their inception to March 2021, using the keywords "phthalate", "cognitive" and "motor". RESULTS: most studies find statistically significant inverse relationships between maternal urinary phthalate concentration during pregnancy and subsequent outcomes in children's cognitive and motor scales, especially in boys rather than girls. However, many associations are not significant, and there were even positive associations, especially in the third trimester. CONCLUSION: the relationship between exposure to phthalates during pregnancy and low results on neurocognitive scales is sufficiently clear to adopt policies to reduce exposure. Further studies are needed to analyze sex differences, coordination and motor scales, and phthalate levels during breastfeeding.

Case reports: Electroacupuncture decreases the climacteric symptoms by calcitonin gene-related peptide modulation.

OBJECTIVE: The purpose of the current study was to evaluate the modulation of Calcitonin gene-related peptide (CGRP) associated to the efficacy of Electroacupuncture (EA) in the reduction of climacteric symptoms. METHODS: Nine women between 51 and 59 years old with climacteric syndrome in menopause or perimenopause were included. Patients with hormone replacement therapy, psychiatric treatment with antidepressants, or acupuncture treatment in the last 3 months were excluded. A 4 Hz EA treatment was performed at acupoints Shenshu (BL-23), Pishu (BL-20), Guanyuan (REN-4), Taixi (KID-3), Fuliu (KID-7), Sanyinjiao (SP-6) and Neiguan (P-6) points. Women were treated two times a week for five consecutive weeks for a total treatment of 10 sessions. The menopause rating scale (MRS) was used to evaluate symptoms reduction and CGRP gene expression was measured before and after 10 EA session. RESULTS: The results shown that climacteric symptoms diminish significantly after EA therapy. CGRP gene expression was down-regulated, evidencing a decrease of 5-fold after EA therapy respect to the initial condition. CONCLUSION: EA treatment was associated with improvement in patients with climacteric syndrome and may be related to modulation of CGRP levels.
