Efectividad de la entrevista motivacional en la atención fisioterápica de los trastornos musculoesqueléticos de la espalda / Effectiveness of the motivational interview in the physiotherapy care of musculoskeletal disorders of the back: A quasi-experimental study

Objetivo: Evaluar la efectividad de la entrevista motivacional (EM) junto al tratamiento fisioterapéutico habitual en pacientes con trastornos musculoesqueléticos (TME) de la espalda en atención primaria (AP). Métodos: Estudio cuasiexperimental en pacientes que iniciaron su tratamiento en el año 2020 en una unidad de fisioterapia tras diagnóstico médico de TME en la espalda, con seguimiento prospectivo de 2grupos con actuación terapéutica: grupo experimental (GE) y grupo de control (GC). Se empleó la EM solo en el GE. A ambos grupos se les entrevistó telefónicamente a los 3y 6meses de finalizar el tratamiento fisioterápico, preguntando por el cumplimiento de pautas domiciliarias y por la percepción subjetiva del estado de salud (escala de Barthel). Se ajustaron modelos de regresión lineales (coeficiente de regresión, IC del 95%) y logísticos (OR, IC del 95%). Resultados: La población de estudio fue de 154 personas (76,6% mujeres). La salud percibida fue significativamente mejor (p<0,001) en el GE que en el GC, tanto a los 3meses de seguimiento (7,4 versus 5,0, respectivamente) como a los 6(7,1 versus 4,6, respectivamente). Hubo una fuerte asociación entre percepción de salud y cumplimiento (coeficiente de regresión 3,0 [IC del 95%=2,5-3,4]). La asociación entre la EM y el cumplimiento terapéutico se mantuvo tras ajustes multivariados (OR a 6meses=383,6 [IC del 95% = 31,0-4.742,4]). Conclusiones: la incorporación de la EM como complemento de los tratamientos de fisioterapia es una herramienta factible y efectiva para mejorar el cumplimiento de las pautas domiciliarias y la percepción subjetiva de salud.

Objective: To evaluate the effectiveness of motivational interviewing (MI) combined with the usual physiotherapy treatment in patients with back musculoskeletal disorders (MSD) in primary care (PC). Methods: Quasi-experimental study with 2groups with therapeutic action (control group and experimental group) and prospective follow-up, in a physiotherapy unit in PC, in patients who began their treatment in 2020, with a medical diagnosis of MSD in the back. MI was used only in the face-to-face visits of the experimental group. Both groups were interviewed by telephone about 3and 6months after finishing the physiotherapy treatment. For this purpose, the Barthel scale was used for the subjective perception of the state of health, and the scale of compliance with home guidelines. Linear (regression coefficient, 95% CI) and logistic (OR, 95% CI) regression models were fitted. Results: The study population was 154 people (76.6% women). Perceived health was significantly better (P<.001) in the experimental group than in the control group, both at 3(7.4 versus 5.0, respectively) and at 6months of follow-up (7.1 versus 4.6, respectively). There was a strong association between perceived health and compliance (regression coefficient 3.0 [95% CI=2.5–3.4]). The strong association between MI and treatment adherence was maintained after multivariate adjustments (6-month OR=383.6 [95% CI 31.0–4742.4]). Conclusions: MI is a feasible and effective complement to physiotherapy treatments to improve compliance with home recommendations and subjective perception of health. (AU)

Seguimiento de los pacientes con diabetes tipo 2 durante la pandemia por COVID-19: un estudio multicéntrico en Atención Primaria / Follow-up of patients with type 2 diabetes during the COVID-19 pandemic: A multicentre study in Primary Care

Antecedentes La pandemia de COVID-19 obligó a tomar medidas que implicaban la desatención a los pacientes con diabetes tipo 2 (DM2). Objetivos Explorar la repercusión de la discontinuidad asistencial sobre los pacientes con DM2. Diseño Estudio observacional retrospectivo multicéntrico. Emplazamiento Cinco centros de atención primaria (AP), que no tenían protocolo de actuación específica para ellos, durante 2020 y 2021. Participantes Pacientes con DM2 en Tenerife, Islas Canarias, España. Mediciones principales De las historias clínicas se extrajeron el sexo y la edad, las variables de seguimiento del programa de detección y control de la enfermedad vascular ateroesclerótica (pEVA), de cumplimiento de los objetivos de control y frecuentación al médico de familia y enfermera comunitaria. Resultados Se incluyó a 3.543 pacientes, 1.772 (50%) mujeres, de ellos 2.204 (62%) mayores de 65 años. La gran mayoría de actividades registradas y objetivos de control disminuyeron en 2020, recuperándose en 2021 sin alcanzar los niveles de 2019. En 2020 aumentaron las consultas telefónicas y disminuyeron las presenciales, tendencia mantenida en 2021 para las telefónicas. Las mujeres y los mayores de 65 años presentaron mayor frecuentación, más registros de actividades y logros de objetivos de control en la mayoría de los parámetros. Conclusiones La pandemia supuso una sobrecarga de la AP que ha afectado a la atención de los pacientes con DM2, que no ha logrado restablecerse a los niveles prepandémicos. Los hombres jóvenes conforman la diana de priorización de esta atención. Las medidas antipandémicas han aumentado la consulta telefónica, un recurso que debe potenciarse (AU)

Background The COVID-19 pandemic meant measures had to be taken that implied the neglect of patients with type 2 diabetes (T2D). Objectives to explore the impact of care discontinuity on patients with T2D in Primary Care (PC) centres, who did not have a specific action protocol for them, during 2020 and 2021. Design Multicenter retrospective observational study. Participants Patients with T2D in Tenerife, Canary Islands, Spain. Main Measurements Sex and age, follow-up variables of atherosclerotic vascular disease detection and control programme (pEVA), compliance with the control objectives and visits to the family practitioner and community nurse were extracted from their medical records. Results 3,543 participants took part in the study, 1,772 (50%) women, 2,204 (62%) of whom were older than 65 years of age. The vast majority of registered activities and control objectives decreased in 2020, recovering in 2021 without reaching 2019 levels. In 2020, telephone consultations increased and in-person consultations decreased, a trend that remained unchanged in 2021 for telephone consultations. Women and those over 65 years of age presented higher frequentation, more activity records and achievement of control objectives in most of the parameters. Conclusions The pandemic caused an overload in the PCs that affected the care of patients with T2D, which has not returned to pre-pandemic levels. Young men are the target for prioritization of this care. Anti-pandemic measures have led to an increase in telephone consultations, a resource that should be strengthened (AU)

The dose-response effect of time between emergency admission and inpatient care on mortality.

To analyse mortality associated to emergency admissions on weekends, differentiating whether the patients were admitted to the Internal Medicine department or to the hospital as a whole. Retrospective follow-up study of patients discharged between 2015 and 2019 in: (a) the Internal Medicine department (n = 7656) and (b) the hospital as a whole (n = 83,146). Logistic regression models were fitted to analyse the risk of death, adjusting for age, sex, severity, Charlson index, sepsis, pneumonia, heart failure and day of admission. Cox models were also adjusted for the time from admission until normal inpatient care. There was a significant increase in mortality for patients admitted in weekends with short stays in Internal Medicine (48, 72 and 96 h: OR = 2.50, 1.89 and 1.62, respectively), and hospital-wide (OR = 2.02, 1.41 and 1.13, respectively). The highest risk in weekends occurred on Fridays (stays ≤ 48 h: OR = 3.92 [95% CI 2.06-7.48]), being no significative on Sundays. The risk increased with the time elapsed from admission until the inpatient department took over care (OR = 5.51 [95% CI 1.42-21.40] when this time reached 4 days). In Cox models patients reached HR = 2.74 (1.00-7.54) when the delay was 4 days. Whether it was Internal Medicine or hospital-wide patients, the risk of death associated with emergency admission in WE increased with the time between admission and transfer of care to the inpatient department; consequently, Friday was the day with the highest risk while Sunday lacked a weekend effect. Healthcare systems should correct this serious problem.

Development, implementation and evaluation of a multinational FLS mentorship programme in Latin America.

Realising the benefits of systematic secondary fracture prevention requires supporting local sites to get started and becoming effective. We here describe the development, implementation and impact of a regional fracture liaison service (FLS) mentorship programme in Latin America that led to 64 FLS getting started and coverage of 17,205 patients. INTRODUCTION: Despite treatments and service models to deliver effective secondary fracture prevention, most patients are left untreated after a fragility fracture. To improve the capability to get FLS started and more effective, we describe the development, implementation and evaluation of an international programme to develop national communities of FLS mentors as part of the Capture the Fracture Partnership in Latin America. METHODS: The IOF regional team and the University of Oxford developed the curriculum and associated resources for training mentors in setting up FLS, service improvement and mentorship. Mentors were selected during a preparatory meeting, trained using live online sessions followed by regular mentor-led post-training meetings. The programme was evaluated using a pre-training needs assessment and post-training evaluation based on Moore's outcomes. RESULTS: The mentorship programme was initiated in Mexico, Brazil, Colombia and Argentina. The mentors were multidisciplinary, including orthopaedic surgery, rehabilitation, rheumatology, endocrinology, geriatrics, gynaecology and internal medicine. There was 100% participation in training sessions and reported satisfaction with the training. Since the initiation of the training programme, 22 FLS have been set up in Mexico, 30 in Brazil, 3 in Colombia and 9 in Argentina, in comparison with two in Chile and none in any other LATAM countries that were not involved in the mentorship programme. This equates to approximately 17,025 additional patients identified from 2019 to 2021 after initiation of mentorship. The mentors have engaged with 58 FLS for service development. Post-training activities include two published national best practice guidelines and other country-specific resources for FLS in the local language. CONCLUSION: Despite the COVID pandemic, the mentorship pillar of the Capture the Fracture Partnership has developed a community of FLS mentors with measurable improvement in national FLS provision. The programme is a potentially scalable platform to develop communities of mentors in other countries.

Impacto de la alteración de la continuidad asistencial en los pacientes con diabetes tipo 2 durante la pandemia de COVID-19 / Impact of the alteration of the continuity of care in diabetes type 2 patients during the COVID-19 pandemic

Objetivo: Valorar la repercusión de la alteración de la continuidad asistencial en pacientes con diabetes mellitus tipo 2 (DM2) durante la pandemia de COVID-19. Material y método: Estudio de seguimiento entre los años 2018 y 2020 de los pacientes con DM2 de un centro de salud. Las actividades asistenciales y preventivas realizadas para su seguimiento fueron comparadas con pruebas estadísticas adecuadas al tipo y distribución de cada variable para un nivel de significación p≤0,05. Resultados: La muestra inicial fue de 587 pacientes con hemoglobina glicosilada (A1c) en 2018 (54% varones), con una edad de 66±11 años en un rango de 29-91 años. En 2020 disminuyeron todos los indicadores de atención: se determinó A1c al 68% de los pacientes (382/558 tras 29 fallecimientos); el 59% permanecía con buen control, el 17% con mal control, el 10% mejoró y el 14% empeoró (p<0,001). Empeoraron menos los pacientes que tenían realizados ECG y retinografía en 2018, aunque no en 2020, que aquellos que no los tenían en 2018, pero sí en 2020 (16 vs. 25%; p<0,001 y 13 vs. 42%; p=0,002). Quienes disminuyeron sus visitas al médico de familia y enfermera presentaron menor empeoramiento que los que las aumentaron (14 vs. 26%; p<0,001 y 17 vs. 23%; p<0,001). Conclusiones: La desatención impidió el control del 32% de los pacientes. El peor control en 2020 fue menor en quienes estaban controlados en 2018, y en quienes disminuyeron su asistencia al centro de salud en 2020. Probablemente una adecuada formación pre-pandémica en autocuidados ha llevado al empoderamiento del paciente durante periodo pandémico (AU)

Aim: To assess the impact of the alteration of the continuity of care in patients with type 2 diabetes during the COVID-19 pandemic. Material and method: Follow-up study with 587 primary care patients with DM2, and control according to the redGDPS-2018 criteria in 2018 and 2020. Activities carried out and control status of patients were compared using statistical tests appropriate to type and distribution of each variable, for a significance level P≤.05. Results: Sample was made up of 587 patients with glycosylated hemoglobin (A1c) in 2018 (54% men), age of 66±11, in range of 29-91 years. All the care indicators decreased in 2020: A1c was determined in 68% of patients (382/558 after 29 deaths); 59% remained with good control, 17% with poor control, 10% improved and 14% worsened (P<.001). Those who had ECG and retinography performed in 2018 and not in 2020 show a lower degree of worsening than those who did not have them done in 2018 but they did in 2020 (16% vs 25%, P<.001 and 13% vs 42%, P=.002). Those who decrease their visits to family doctor and nurse show less deterioration than those who increase them (14% vs 26%; P<.001 and 17% vs 23%; P<.001). Conclusions: Inattention impeded control of 32% of the patients. Poor control in 2020 was lower in those who were controlled in 2018, and who decreased their attendance at the health center in 2020. Possibly adequate pre-pandemic training in self-care has led to the empowerment of the patient during a pandemic period (AU)

The influence of hospital antimicrobial use on carbapenem-non-susceptible Enterobacterales incidence rates according to their mechanism of resistance: a time-series analysis.

BACKGROUND: Carbapenem non-susceptible Enterobacterales (CNSE) can be broadly divided into those that produce carbapenemases (carbapenemase-producing Enterobacterales (CPE)), and those that harbour other mechanisms of resistance (non-carbapenemase-producing CNSE (NCP-CNSE)). AIM: To determine the predictors of CNSE nosocomial incidence rates according to their mechanism of resistance. METHODS: A time-series analysis was conducted (July 2013 to December 2018) to evaluate the relationship in time between hospital antibiotic use and the percentage of adherence to hand hygiene with the CNSE rates. FINDINGS: In all, 20,641 non-duplicated Enterobacterales isolates were identified; 2.2% were CNSE. Of these, 48.1% and 51.9% were CPE and NCP-CNSE, respectively. Of the CPE, 78.3% possessed a blaOXA-232 gene. A transfer function model was identified for CNSE, CPE, and OXA-232 CPE that explained 20.8%, 19.3%, and 24.2% of their variation, respectively. According to the CNSE and CPE models, an increase in piperacillin-tazobactam (TZP) use of 1 defined daily dose (DDD) per 100 hospital patient-days (HPD) would lead to an increase of 0.69 and 0.49 CNSE and CPE cases per 10,000 HPD, respectively. The OXA-232 CPE model estimates that an increase of 1 DDD per 100 HPD of TZP use would lead to an increase of 0.43 OXA-232 CPE cases per 10,000 HPD. A transfer function model was not identified for NCP-CNSE, nor was there an association between the adherence to handhygiene and the CNSE rates. CONCLUSION: The use of TZP is related in time with the CPE nosocomial rates, mostly explained by its effect on OXA-232 CPE.

Rebound tonometry with re-sterilised tips versus Goldmann applanation tonometry in children. / Tonometría de rebote con puntas nuevas y reesterilizadas versus tonometría de aplanación Goldmann en niños.

BACKGROUND: The Goldmann applanation tonometer (TAG) is the gold standard for the measurement of intraocular pressure (IOP). In paediatric patients this measurement is challenging. The rebound tonometer (TRB) is an easy to use instrument. In the National Ophthalmology Unit (UNO) the tips of the TRB are re-sterilised (TRB RE). OBJECTIVE: To evaluate the correlation between TRB with new and re-sterilised tips compared to TAG. MATERIALS AND METHODS: A cross-sectional study was conducted on 25 healthy patients between 8 and 12 years of age, chosen at random, and seen in the UNO outpatients department during 2019. IOPs were measured with TRB using re-sterilized tips and then with a new tip, and finally with TAG. RESULTS: There was a correlation between IOP measured with TAG and IOP measured with TRB (P=.0011). No correlation was found between TAG and TRB RE, or TRB with TRB RE. CONCLUSIONS: The TRB can be used in paediatric patients, taking into account that IOP usually overestimates with respect to TAG.

Sequence and transcript expression of the super-kdr locus of the horn fly, Haematobia irritans.

In horn flies, Haematobia irritans irritans (Diptera: Muscidae) (Linnaeus, 1758), target site resistance to pyrethroids can be diagnosed by an allele-specific PCR that genotypes individual flies at both the super-kdr (skdr) and the knock down resistance (kdr) associated loci. When this technique uses genomic DNA as template, modifications, such as alternative RNA splicing and RNA editing are not specifically detected. Alternative splicing at the skdr locus has been reported in Dipterans; thus, the genomic DNA-based allele-specific PCR may not accurately reflect the frequency of the skdr mutation in horn fly field populations. To investigate if alternative splicing occurs at the skdr locus of horn flies, genomic DNA and cDNA sequences isolated from two wild populations and two laboratory-reared colonies with varying degrees of pyrethroid resistance were compared. There was no indication of alternative splicing at the super-kdr locus neither in the wild populations nor in the laboratory-reared colonies.

Molecular detection of Rickettsia species in ticks collected in the Mexico-USA transboundary region.

Zoonotic tick-borne diseases, including those caused by Rickettsia species, continue to have serious consequences for public health worldwide. One such disease that has emerged as a major problem in several countries of the American continent is the Rocky Mountain Spotted Fever (RMSF) caused by the bacterium Rickettsia rickettsii. Several tick species are capable of transmitting R. rickettsia, including Amblyomma cajennense, A. aureolatum, A. imitator, Rhipicephalus sanguineus, Dermacentor andersoni, D. variabilis and possibly A. americanum. Despite previous reports in Mexico linking new outbreaks of RMSF to the presence of these tick species, no robust measures have tackled transmission. In the present study, we amplified R. rickettsii from 109 test DNA samples extracted from ticks collected from several animals and humans of Tamaulipas, Mexico, between November 2015 and December 2017. Our analysis revealed the presence of R. rickettsii in six samples and these findings contribute to a spatial distribution map that is intended to minimize the risk of transmission to humans.

Resistance profile and molecular characterization of pyrethroid resistance in a Rhipicephalus microplus strain from Colombia.

Intensive use of chemical acaricides for the control of cattle ticks (Rhipicephalus microplus) has led to the development of multiple acaricide resistance in Colombia. The present study aimed to characterize, using toxicological bioassays and molecular biology techniques, the resistance profile of a tick strain isolated from the Arauca state, Northeast Colombia. Commercial acaricides were used in adult immersion tests to determine its in vitro efficacies. Deltamethrin showed very low activity (4-7.3%), a mixture of cypermethrin and chlorpyrifos had intermediate efficacy (64-75.2%), and ethion presented the highest activity (88.5-100%). A colony (Arauquita strain) was established and larval immersion tests confirmed high resistance level to deltamethrin (241-fold) and susceptibility to ivermectin. A quantitative polymerase chain reaction-high resolution melt technique was used to identify single nucleotide polymorphisms (SNPs) in the para-sodium channel gene. All of the genotyped individuals were mutant, presenting one (n = 7), two (n = 7) or three (n = 9) SNPs previously associated with pyrethroid resistance. Sequencing revealed a novel mutation (F712L), that was found for the first time in R. microplus ticks from South America. This is the first description of mutations associated with pyrethroid resistance in R. microplus from Colombia. The acaricide resistance pattern found in the Arauquita strain is similar to other parts of Colombia.

Development of Surface-Coated Polylactic Acid/Polyhydroxyalkanoate (PLA/PHA) Nanocomposites.

This work reports on the design and development of nanocomposites based on a polymeric matrix containing biodegradable Polylactic Acid (PLA) and Polyhydroxyalkanoate (PHA) coated with either Graphite NanoPlatelets (GNP) or silver nanoparticles (AgNP). Nanocomposites were obtained by mechanical mixing under mild conditions and low load contents (<0.10 wt %). This favours physical adhesion of the additives onto the polymer surface, while the polymeric bulk matrix remains unaffected. Nanocomposite characterisation was performed via optical and focused ion beam microscopy, proving these nanocomposites are selectively modified only on the surface, leaving bulk polymer unaffected. Processability of these materials was proven by the fabrication of samples via injection moulding and mechanical characterisation. Nanocomposites showed enhanced Young modulus and yield strength, as well as better thermal properties when compared with the unmodified polymer. In the case of AgNP coated nanocomposites, the surface was found to be optically active, as observed in the increase of the resolution of Raman spectra, acquired at least 10 times, proving these nanocomposites are promising candidates as surface enhanced Raman spectroscopy (SERS) substrates.

Alginate/Gelatin Hydrogels Reinforced with TiO2 and ß-TCP Fabricated by Microextrusion-based Printing for Tissue Regeneration.

Three-dimensional (3D) printing technologies have become an attractive manufacturing process to fabricate scaffolds in tissue engineering. Recent research has focused on the fabrication of alginate complex shaped structures that closely mimic biological organs or tissues. Alginates can be effectively manufactured into porous three-dimensional networks for tissue engineering applications. However, the structure, mechanical properties, and shape fidelity of 3D-printed alginate hydrogels used for preparing tissue-engineered scaffolds is difficult to control. In this work, the use of alginate/gelatin hydrogels reinforced with TiO2 and ß-tricalcium phosphate was studied to tailor the mechanical properties of 3D-printed hydrogels. The hydrogels reinforced with TiO2 and ß-TCP showed enhanced mechanical properties up to 20 MPa of elastic modulus. Furthermore, the pores of the crosslinked printed structures were measured with an average pore size of 200 µm. Additionally, it was found that as more layers of the design were printed, there was an increase of the line width of the bottom layers due to its viscous deformation. Shrinkage of the design when the hydrogel is crosslinked and freeze dried was also measured and found to be up to 27% from the printed design. Overall, the proposed approach enabled fabrication of 3D-printed alginate scaffolds with adequate physical properties for tissue engineering applications.

Moderate alcohol consumption and depression - a longitudinal population-based study in Sweden.

BACKGROUND AND AIMS: The interrelationship between alcohol consumption and depression is complex, and the direction of the association is unclear. We investigated whether alcohol consumption influences the risk of depression while accounting for this potential bidirectionality. METHODS: A total of 10 441 individuals participated in the PART study in 1998-2000, 8622 in 2001-2003, and 5228 in 2010. Participants answered questions on their alcohol consumption, symptoms of depression, childhood adversity, and sociodemographic, socioeconomic, psychosocial, and lifestyle factors. A total of 5087 participants provided repeated information on alcohol consumption. We used marginal structural models to analyze the association between alcohol consumption and depression while controlling for previous alcohol consumption and depressive symptoms and other time-varying confounders. RESULTS: Non-drinkers had a higher depression risk than light drinkers (≤7 drinks/week) (risk ratio: 1.7; 95% confidence interval 1.3-2.1). Consumers of seven-fourteen drinks/week had a depression risk similar to that of light drinkers. Hazardous drinking was associated with a higher risk of depression than non-hazardous alcohol consumption (risk ratio: 1.8, 95% confidence interval: 1.4-2.4). CONCLUSION: Light and moderate alcohol consumption and non-hazardous drinking were associated with the lowest risk of subsequent depression after accounting for potential bidirectional effects. Hazardous drinking increased the risk of depression.

Aplicación de la Escala de Tabaquismo para Atención Primaria (ETAP) en la práctica clínica / Application of the Smoking Scale for Primary Care (ETAP) in clinical practice

OBJETIVO: Averiguar si la escala de tabaquismo ETAP, que mide la exposición acumulada al tabaco tanto activa como pasivamente, es aplicable y efectiva en la práctica clínica de la atención primaria para la prevención del infarto agudo de miocardio (IAM). Emplazamiento Centro de salud de Barranco Grande, en Tenerife. DISEÑO: Estudio de 61 casos (IAM) y 144 controles. Muestreo con arranque aleatorio, sin apareamiento. Se realizó análisis de curvas COR-II y se estimó la efectividad mediante sensibilidad y valor predictivo negativo (VPN). Se administró una encuesta a los médicos de familia participantes sobre la aplicabilidad de la ETAP en la consulta. RESULTADOS: La opinión de los médicos participantes fue unánimemente favorable: la ETAP fue de fácil uso en la consulta, necesitó menos de 3 min por paciente y resultó útil para reforzar la intervención preventiva. La curva COR-II de la ETAP mostró que 20 años de exposición era el mejor punto de corte, con un área bajo la curva de 0,70 (IC 95%: 0,62-0,78) y una combinación de sensibilidad (98%) y VPN (96%) para el IAM. Al estratificar edad y sexo, en todos los grupos se alcanzaron sensibilidades y VPN cercanos al 100%, salvo en los hombres de edad ≥ 55años, en quienes el VPN cayó hasta el 75%. CONCLUSIONES: Los resultados apuntan a que ETAP es una herramienta válida que puede ser aplicable y efectiva en la práctica clínica de la atención primaria para la prevención del IAM relacionado con el consumo de tabaco

OBJECTIVE: To determine if the ETAP smoking scale, which measures accumulated exposure to tobacco, both actively and passively, is applicable and effective in the clinical practice of Primary Care for the prevention of acute myocardial infarction (AMI). Location Barranco Grande Health Centre in Tenerife, Spain. DESIGN: A study of 61 cases (AMI) and 144 controls. Sampling with random start, without matching. COR-II curves were analysed, and effectiveness was estimated using sensitivity and negative predictive value (NPV). A questionnaire was provided to participating family physicians on the applicability of ETAP in the clinic. RESULTS: The opinion of the participating physicians was unanimously favourable. ETAP was easy to use in the clinic, required less than 3 min per patient, and was useful to reinforce the preventive intervention. The ETAP COR-II curve showed that 20 years of exposure was the best cut-off point, with an area under the curve of 0.70 (95%CI: 0.62-0.78), and a combination of sensitivity (98%) and NPV (96%) for AMI. When stratifying age and gender, all groups achieved sensitivities and NPVs close to 100%, except for men aged ≥ 55years, in whom the NPV fell to 75%. CONCLUSIONS: The results indicate that ETAP is a valid tool that can be applied and be effective in the clinical practice of Primary Care for the prevention of AMI related to smoking exposure

Beer effects on postprandial digestive symptoms and gastroesophagic physiology.

BACKGROUND: Beer has been related to gastroesophageal reflux (GER) and dyspepsia, based on its alcohol and gas content. The aim of this study is to evaluate the association between moderate consumption of traditional and alcohol-free beer and upper digestive symptoms, gastric accommodation and GER. METHODS: Healthy adults without frequent gastrointestinal symptoms and GER disease were included. The intervention involved administration of traditional beer to 10 subjects (substudy 1) and alcohol-free beer to 20 (substudy 2); control intervention entailed administration of water. Study duration was 2 weeks (control/intervention). Postprandial gastric accommodation was assessed through the maximum tolerated volume during a nutrient drink test after the ingestion of water (day 1) and beer (day 8), in which symptoms of dyspepsia were evaluated every 5 minutes. An impedance-pH monitoring assessed 24 hours and post-NDT GER (days 1 and 8). Symptoms were evaluated daily during the study. The defined variables were compared between visits and weeks using a nonparametric test for paired data. KEY RESULTS: Dyspepsia symptoms showed a progressive increase during the NDT for both interventions in the 2 substudies, though no significant differences were detected in the MTV analysis. No differences were detected in the sum of weekly symptoms. The analysis of impedance-pH monitoring did not show any differences between intervention and control visits for both interventions. CONCLUSIONS AND INFERENCES: Moderate consumption of traditional and alcohol-free beer does not increase dyspeptic symptoms or GER in healthy subjects, whether in a controlled-intake or real-life situation. Neither gastric accommodation nor reflux episodes are modified in this context.

Seroepidemiology of Bovine Herpes Virus-1 Infection in Water Buffaloes from the state of Veracruz, Mexico.

Water buffaloes (Bubalus bubalis) were introduced to Mexico at the end of the last century. In Mexico, buffaloes are commonly pastured together with cattle; however few studies have been done on buffalo herd health in Mexico. We hypothesized that a better knowledge of the epidemiology of infections shared between cattle and buffaloes may improve herd profitability and promote buffalo production in areas unsuitable to cattle farming. This study aimed to determine the prevalence of antibodies against bovine herpes virus - 1 (BoHV1) in water buffaloes raised on six farms from the state of Veracruz, Mexico. Of 368 buffaloes sampled, 217 (59%) were seropositive for BoHV-1. Age was identified as a risk factor for BoHV-1 infection with buffaloes older than 5 years being the most likely to be infected. Animals more than 7 years old had the highest prevalence (86.0%). Females and males had similar seroprevalence rates. Females with history of abortion had higher prevalence of antiBoHV-1 antibodies than those with no record of abortion. Buffaloes and cattle were raised together in only one of the six farms under study. Interaction with cattle was not a risk factor for BoHV-1 seropositivity. This study showed that BoHV-1 is prevalent among buffalo herds in the state of Veracruz, Mexico. Buffaloes appear to play an important role in the epidemiology of BoHV-1 infection in parts of Mexico when there is no apparent risk of interaction with cattle. Animal health programs established to mitigate the burden caused by BoHV-1 must take into consideration buffaloes when this bovid species is part of the agroecosystem shared with cattle.
