[Evaluation of the change in pneumococcal vaccination in 2018 in adults in the Community of Madrid]. / Evaluación del cambio de pauta de vacunación frente al neumococo de 2018 en la población adulta en la Comunidad de Madrid.

BACKGROUND: In the Community of Madrid since 2005 vaccination against pneumococcus in adults from 60 years of age has been carried out with pneumococcal polysaccharide vaccine (PPV23). In January 2018, the guideline changed in favor of pneumococcal conjugate vaccine (PCV13). The objective of this study was to analyze the data of pneumococcal vaccination and to evaluate the implementation of the new guideline of vaccination against pneumococcus in adults in the Community of Madrid. METHODS: Cross-sectional study to estimate vaccine coverage by a retrospective review of the record of vaccination history of people ≥60 years resident in the Community of Madrid. RESULTS: In the Community of Madrid until 2018, 83% of the population were vaccinated with PPV23, 6% with PCV13 and 11% with both vaccines. 96.5% came from Primary Care records. The doses administered of PCV13 surpassed those of PPV23 in ≥60 years in all age groups. 78,660 people ≥60 years were vaccinated with PCV13 (19.5% without risk factors, 67.3% with chronic diseases, 2.5% of the high-risk group and 10.7% belonging to both groups). CONCLUSIONS: In 2018, following Community of Madrid recommendations, 6,639 people were not properly vaccinated with PCV13 and 72,021 (91.6%) were properly vaccinated. The greatest confusion occurred in people ≥60 years without risk factors who had a previous PPV23 and did not require another vaccine but received a PCV13 without complying with the recommended schedule.

Outcomes in weight loss, fasting blood glucose and glycosylated hemoglobin in a sample of 415 obese patients, included in the database of the European accreditation council for excellence centers for bariatric surgery with laparoscopic one anastomosis gastric bypass.

BACKGROUND: Obesity is a risk factor for the development of diseases such as type 2 Diabetes Mellitus. Bariatric surgery with laparoscopic single anastomosis gastric bypass is an effective treatment for morbid obesity and diabetes type 2 complete remission, and it has been proven to generate an improvement in glycemic levels and glycosylated hemoglobin (HbA1c) keeping the weight loss for a long time. MATERIAL AND METHODS: In a period of time between June 2002 until May 2012, 2070 patients underwent surgery with LOAGB technique. Between January 2010 an May 2012, 415 patients were included in the European Accreditation Council for Excellence Centers for Bariatric Surgery (EAC-BS) database, from which 79 patients with a glycemic level disturbance in the preoperative blood sample where chosen. Of this group, 47 patients were pre-diabetic (fast plasma glucose ≥ 110 mg/dl ≤ 125 mg/dl) and glycosylated hemoglobin (HbA1c) levels between 5.7-6.4% and 32 were diabetic (fast plasma glucose ≥ 126 mg/dl) and glycosylated hemoglobin (HbA1c) levels ≥ 6.5%. We described the weight evolution, the excess body mass index lost percentage (%EBMIL) the glycemia and the glycosylated hemoglobin levels; and we reported regular laboratory controls during the first year after surgical intervention. RESULTS: Both patient groups achieved their lowest mean weight loss 12 months after surgery, being average weight in the pre-diabetic group 62,41 ± 10,93 and 68,36 ± 11,16 in the diabetic group. Since 3 months after surgery, pre-diabetic patients achieve a mean BMI < 30, according to the Spanish Society for Obesity Study (SEEDO 2007) this amount is outside of the definition of obesity. Not being the case of the diabetic patients who don´t achieve this result until 6 months after surgery. The weight loss was excellent in both study groups, achieving an excess body mass index loss percentage (% EBMIL) greater than 65%, since the first three-month postoperative control. Glycemia levels descend in both groups, achieving the pre-diabetic group a mean glycemia level of < 110 mg/ dl in the second day after LOAGB surgery. Pre-diabetic patients maintain more stable glycemia with better controls, and very favorable outcomes 12 months after surgery. The diabetic patients achieve the mean glycemia level of < 110 mg/dl at the first month after surgery and maintained it 12 months after surgery which is the time of this study. The glycosylated hemoglobin levels descended in both groups, achieving levels of 4% three months after surgery in the prediabetic group and 4.8% at six months in the diabetic group. CONCLUSION: LOAGB proved to be an efficient bariatric technique for complete remission of pre-diabetes and diabetes mellitus type 2 and also with the excess weight loss resolution. We showed that the excess weight loss, the glycemia and glycosylated hemoglobin levels continue being normal after one year of follow up after surgery. The best results are obtained in pre-diabetic patients who underwent LOAGB, this group is integrated with people who are at high risk of suffering a deterioration of their obesity and a rapid advance of the diabetes and the associated comorbidities, that's why surgery has to be performed as soon as possible when the medical exam continues being favorable.

Introducción: La obesidad es un factor de riesgo para el desarrollo de enfermedades tales como la diabetes mellitus tipo II. La cirugía bariátrica laparoscópica de una anastomosis también conocida como mini-bypass con las modificaciones del doctor Carbajo, es un tratamiento efectivo para el manejo de la obesidad mórbida y para obtener una completa remisión de la diabetes tipo II y se ha demostrado que se genera una mejoría de los niveles de glicemia y de hemoglobina glicosilada (HbA1c) manteniendo la pérdida de peso por un largo período de tiempo. Material y métodos: En un período de tiempo entre junio del 2002 hasta mayo de 2012, 2070 pacientes se intervinieron quirúrgicamente con la técnica bariátrica laparoscópica de una anastomosis gástrica (BAGUA). Entre enero de 2010 y mayo de 2012, 415 pacientes fueron incluidos en la base de datos del Consejo Europeo de acreditación para centros de excelencia de cirugía bariátrica, de los cuales se escogieron 79 pacientes que presentaban trastornos de los niveles de glicemia en sus pruebas sanguíneas preoperatorias. De este grupo 47 pacientes se clasificaron como pre-diabéticos con niveles de glucosa en sangre ≥110 mg/ dl ≤ 125 mg/dl y unos niveles de hemoglobina glicosilada ( HbA1C) entre 5.7-6.4% y 32 como diabéticos con niveles de glucosa en sangre ≥ 126 mg/dl y niveles de hemoglobina glicosilada (HbA1C) ≥ 6.5%. Nosotros describimos la evolución de los cambios en el peso, el porcentaje de pérdida del índice de masa corporal, los niveles de glicemia y de hemoglobina glicosilada de los pacientes estudiados y reportamos los resultados de los controles de laboratorio practicados regularmente durante el primer año postoperatorio. Resultados: ambos grupos de pacientes alcanzaron su máxima pérdida de peso a los 12 meses postoperatorios, siendo el peso promedio en el grupo de pre-diabéticos 62,41 ± 10,93 y 68,36 ± 11,16 en el grupo de diabéticos. Los pacientes pre-diabéticos alcanzaron desde los 3 meses de postoperatorio un índice de masa corporal (IMC) < 30, que de acuerdo con el estudio sobre Obesidad de la Sociedad Española (SEEDO 2007) esta cantidad se encuentra por fuera de la definición de obesidad, no siendo el caso del grupo de pacientes diabéticos que no alcanzaron este resultado hasta los 6 meses de postoperatorio. La pérdida de peso fue excelente en ambos grupos alcanzando un porcentaje de pérdida de índice de masa corporal mayor de 65% desde los primeros 3 meses de control postoperatorio. Los niveles de glicemia bajaron en ambos grupos, alcanzando el grupo de pre-diabéticos un nivel de glicemia < 110 mg/dl desde el segundo día postoperatorio de BAGUA. Los pacientes pre-diabéticos mantuvieron un nivel de glicemia estable con mejor control y una muy favorable evolución a los 12 meses de postoperatorio. Los pacientes diabéticos alcanzaron el nivel de glicemia < 110 mg/dl en el primer mes postoperatorio y lo mantuvieron así a los 12 meses de postoperatorio, tiempo en el que se elaboró este estudio. Los niveles de hemoglobina glicosilada descendieron en ambos grupos, alcanzando niveles de 4% a los 3 meses de postoperatorio en los pacientes prediabéticos y un 4,8% a los 6 meses en el grupo de los pacientes diabéticos. Conclusión: BAGUA mostró ser una técnica quirúrgica bariátrica eficiente para la remisión completa de la pre-diabetes y la diabetes tipo II así como de la pérdida del exceso de peso. Nosotros demostramos que la pérdida del exceso de peso, los niveles de glicemia y de hemoglobina glicosilada continuaron siendo normales al año de seguimiento postoperatorio. Los mejores resultados se obtuvieron en el grupo de pre-diabéticos a quienes se les practicó BAGUA. Este grupo está integrado por personas que se encuentran en riesgo de sufrir un deterioro de su obesidad y un rápido avance hacia diabetes y a las comorbilidades asociadas, está es la razón por la cual esta cirugía debe realizarse lo más pronto posible mientras las pruebas médicas de los pacientes sigan siendo favorables.

Effectiveness of 23-valent pneumococcal polysaccharide vaccine in adults aged 60 years and over in the Region of Madrid, Spain, 2008-2011.

Invasive pneumococcal disease (IPD) is a notifiable disease in the Region of Madrid. The 23-valent pneumococcal polysaccharide vaccine (PPV23) is recommended for children and adults aged two years or over with a high risk of disease, and for all adults aged 60 and over. We describe the evolution of IPD incidence from 2008 to 2011 in people aged 60 years and over and PPV23 vaccine effectiveness (VE). VE is estimated using both the screening method and indirect cohort method. The incidence of IPD varied from 20.0 in 2008 to 15.2 per 100,000 inhabitants in 2011 (RR: 0.8; 95% CI: 0.6­0.9). Adjusted VE estimated with the screening method was 68.2% (95% CI: 56.2­76.9). VE with the Broome method was 44.5% (95% CI: 23.8­59.6) for all PPV23 serotypes, and 64.4% (95% CI: 45.2­76.8) for PPV23 serotypes not included in conjugate vaccines. VE was lower in patients aged 80 years and older (25.5%; 95% CI:-23.2 to 55.0) and those with highrisk medical conditions (31.7%; 95% CI: -2.2 to -54.4). Adjusted VE was 44.5% (95% CI: 19.4-61.8) within 5 years of vaccination and 32.5% (95% CI: -5.6 to 56.9) after 5 years. These results are compatible with current recommendations for PPV23.

Inhibition of citrus fungal pathogens by using lactic acid bacteria.

The effect of lactic acid bacteria (LAB) on pathogenic fungi was evaluated and the metabolites involved in the antifungal effect were characterized. Penicillium digitatum (INTA 1 to INTA 7) and Geotrichum citri-aurantii (INTA 8) isolated from decayed lemon from commercial packinghouses were treated with imazalil and guazatine to obtain strains resistant to these fungicides. The most resistant strains (4 fungal strains) were selected for evaluating the antifungal activity of 33 LAB strains, among which only 8 strains gave positive results. The antifungal activity of these LAB strains was related to the production of lactic acid, acetic acid, and phenyllactic acid (PLA). A central composite design and the response surface methodology were used to evaluate the inhibitory effect of the organic acids produced by the LAB cultures. The antifungal activity of lactic acid was directly related to its concentration; however, acetic acid and PLA showed a peak of activity at 52.5 and 0.8 mM, respectively, with inhibition rates similar to those obtained with Serenade((R)) (3.0 ppm) imazalil (50 ppm) and guazatine (50 ppm). Beyond the peak of activity, a reduction in effectiveness of both acetic acid and PLA was observed. Comparing the inhibition rate of the organic acids, PLA was about 66- and 600-fold more effective than acetic acid and lactic acid, respectively. This study presents evidences on the antifungal effect of selected LAB strains and their end products. Studies are currently being undertaken to evaluate the effectiveness in preventing postharvest diseases on citrus fruits.

UV-C radiation based methods for aqueous metoprolol elimination.

The endocrine disruptor metoprolol has been oxidised in aqueous solution by means of the systems UV-C, UV-C/H(2)O(2), UV-C/percarbonate, UV-C/monopersulfate, UV-C/TiO(2), UV-C/H(2)O(2)/TiO(2) and photo-Fenton. From simple photolysis experiments the quantum yield of metoprolol has been calculated (roughly 5x10(-3) mol Einstein(-1) at circumneutral pH). Addition of free radicals promoters significantly enhanced the metoprolol depletion rate. Mineralization degree was negligible when no promoter was added, while low values were achieved in the presence of either inorganic peroxides or titanium dioxide. The combination of radiation, hydrogen peroxide and TiO(2) increased the mineralization level up to values in the proximity of 45-50% under the best conditions investigated. The photo-Fenton process was the best system in terms of total oxidation (mineralization degree 70%) when optimum conditions were applied.

Effects of a balanced energy and high protein formula diet (Vegestart complet®) vs. low-calorie regular diet in morbid obese patients prior to bariatric surgery (laparoscopic single anastomosis gastric bypass): a prospective, double-blind randomized study.

OBJECTIVE: Bariatric surgery is considered the only therapeutic alternative for morbid obesity and its comorbidities. High risks factors are usually linked with this kind of surgery. In order to reduce it, we consider that losing at least 10% of overweight in Morbid Obese (MO) and a minimum of 20% in Super- Obese patients (SO) before surgery, may reduce the morbidity of the procedure. The aim of our study is to demonstrate the effectiveness and tolerance of a balanced energy formula diet at the preoperative stage, comparing it against a low calorie regular diet. METHOD: We studied 120 patients divided into two groups of 60 each, group A was treated 20 days prior to bariatric surgery with a balanced energy formula diet, based on 200 Kcal every 6 hours for 12 days and group B was treated with a low calorie regular diet with no carbs or fat. The last eight days prior to surgery both groups took only clear liquids. We studied the evolution of weight loss, the BMI, as well as behavior of co-morbidities as systolic blood pressure, diastolic blood pressure, glucose controls and tolerance at the protocol. RESULTS: The study shows that patients undergoing a balanced energy formula diet improved their comorbidities statistically significant in terms of decrease in weight and BMI loss, blood pressure and glucose, compared to the group that was treated before surgery with a low calorie regular diet. Nevertheless both groups improving the weight loss and co-morbidities with better surgical results and facilities. CONCLUSION: A correct preparation of the Morbid Obese patients prior of surgery can reduce the operative risks improving the results. Our study show that the preoperative treatment with a balanced energy formula diet as were included in our protocol in patients undergoing bariatric surgery improves statistical better their overall conditions, lowers cardiovascular risk and metabolic diseases that the patients with regular diet alone.

Comparison of different advanced oxidation processes (AOPs) in the presence of perovskites.

The efficacy of the oxidation systems: O3, UV radiation, O3/UV radiation, O3/perovskite, UV radiation/perovskite, O3/UV radiation/perovskite, H2O2/UV radiation, H2O2/UV radiation/perovskite, has been investigated by using pyruvic acid as probe compound. Under the operating conditions used, the combination of UV radiation and hydrogen peroxide (with or without perovskites) leads to the fastest pyruvic acid removal while the best results in terms of mineralization degree are obtained when combining O3/UV radiation/perovskite. The effect of the variables: inlet ozone (15-75 mg L(-1)) and initial pyruvic acid (10(-3) to 10(-2)M) concentrations, catalyst load (0.01-1.5 g L(-1)) and pH (2-9) was investigated for the photocatalytic ozonation. The most influencing parameter was the ozone concentration fed to the photoreactor. A zero order was observed for pyruvic acid concentration and close to zero for catalyst load. Some deactivation is observed after reusing the catalyst, likely due to leaching of the active phase.

Photocatalysis of fluorene adsorbed onto TiO2.

The adsorption of fluorene onto TiO2 has been investigated by conducting equilibrium and kinetic experiments. Adsorption isotherms have been evaluated at two different pHs in the range of temperatures 296-325 K. The type III isotherm shapes obtained were modelled by considering several expressions taken from the literature. Temperature exerted a positive influence in fluorene uptake. Addition of phosphates involved a negative effect when computing the final equilibrium fluorene removal. The kinetic experiments carried out at 296 K corroborated the competitiveness of phosphates to occupy the active sites on the titania surface. Nevertheless, equilibrium conditions are faster achieved at pH 2 than at pH 5. The photocatalysis of fluorene at different initial concentrations of the parent compound revealed a slight improvement of the process at pH 5 if compared to the results obtained at pH 2. A Langmuir-Hinselwood representation of the data confirms the previous statement. Catalyst load shows an optimum, concentration values of the photocatalyst above the optimum provoke a decrease in the fluorene abatement rate. Reutilisation of the catalyst indicates that fluorene is completely eliminated from the solid, i.e. it is suggested that fluorene and intermediates are surface oxidised.

Effect of supercritical CO2 in modified polystyrene 3D latex arrays.

The effect of supercritical CO(2) (scCO(2)) in 3D latex arrays formed by monodispersed particles of polystyrene (PS), PS cross-linked with divinylbenzene (PS-DVB), and PS block copolymers with 2-hydroxyethyl methacrylate (PS-HEMA), methacrylic acid (PS-MA), acrylic acid (PS-AA), itaconic acid (PS-IA), and a mixture of methacrylic and itaconic acid (PS-IA-MA) has been studied. Sorption of CO(2) into the polymer particles leads to a decrease in the glass transition temperature of the polymer and the swelling of the particles and induces their coalescence. 3D-latex arrays of the former compositions were treated in scCO(2) at temperatures and pressures ranging from 40 to 80 degrees C and from 85 to 197 bar, respectively. The effect of CO(2) on the polymeric template was assessed by scanning electron microscopy and N(2) adsorption analysis. Bare PS and PS-HEMA particles sintered readily in scCO(2) at 40 degrees C and 85 bar. On the other hand, particles containing carboxylic acid groups on their surface (PS-MA, PS-AA, PS-IA, and PS-IA-MA) were, at the same temperature and pressure, more resistant to the CO(2) treatment. For a given polymer composition, the sorption of CO(2) inside the polymer particles, the swelling, and the degree of coalescence depend on the pressure, temperature, and time of the CO(2) treatment. Analysis of the pore size distributions from the N(2) adsorption data has allowed us to quantify the degree of coalescence of the particles in the matrix. By careful control of the experimental variables, the coalescence of the 3D latex array could be finely tuned using CO(2).

Gastric pouch carcinoma after gastric bypass for morbid obesity.

The relationship between bariatric surgery and gastric cancer is conjectural. We present a 52-year-old woman with BMI 45 operated initially by a Lap-Band procedure complicated by gastric wall erosion of the band 9 months later. She was re-operated and the band was removed. She subsequently underwent a Roux-en-Y gastric bypass. 5 years after, gastric carcinoma was discovered in the gastric pouch. Because of varied symptoms following bariatric surgery, patients may not present promptly with symptoms related to a gastric carcinoma.

Synthesis of ordered macroporous SiO2 in supercritical CO2 using 3D-latex array templates.

Ordered macroporous SiO(2) membranes were produced by the decomposition of silicon alkoxides in supercritical carbon dioxide (scCO(2)) using 3D-latex arrays as templates.

Characterization of latex particle arrays by gas adsorption.

Assemblies of colloidal particles are frequently used in novel applications, and this requires nondestructive methods allowing overall characterization of the sample and collection of information about the quality of the arrays. From suspensions of polystyrene, poly[styrene-co-(2-hydroxyethylmethacrylate)], poly[styrene-co-acrylic acid], and poly[styrene-co-methacrylic acid], assemblies of spherical particles were obtained by elimination of the solvent in different ways-evaporation, gravity deposition, and filtration. These latex particle packings were characterized by scanning and transmission electron microscopy and by gas adsorption to determine the efficiency of packing. The surface area, total pore volume, and pore size distributions obtained from the adsorption and desorption data were related to characteristic parameters calculated for cubic close-packed spherical particles.

One anastomosis gastric bypass: a simple, safe and efficient surgical procedure for treating morbid obesity.

The One Anastomosis Gastric Bypass has been developed from the Mini Gastric Bypass procedure as originally described by Robert Rutledge. The modification of the original procedure consists of making a latero-lateral gastro-jejunal anastomosis instead of a termino-lateral anastomosis, as is carried out as described in the original procedure. The rationale for these changes is to try to reduce exposure of the gastric mucosa to biliopancreatic secretions because of their potentially carcinogenic effects with longer term exposure, which is the major criticism of the original technique. If we fix the jejunal loop to the gastric pouch some centimetres up to the gastro-jejunal anastomosis the biliopancreatic secretions have less possibility of coming into the gastric cavity (gravity force). Furthermore, if the anastomosis is latero-lateral this possibility is reduced even more. In addition, the intestinal loop reinforces the staple line against disruption, and also the gastric pouch against dilatation.

Influence of preservation solution on early lung function (Euro-Collins vs Perfadex).

BACKGROUND: This clinical study was performed to evaluate the efficiency of 2 different preservation solutions (Euro-Collins [EC] vs Perfadex [P]) on organ function in human lung transplantation. METHODS: The donor lungs for 46 patients were flushed either with EC solution (25 cases, EC group) or Perfadex (21 cases, P group). Transplant function was assayed using PaO2/FiO2 ratio after transplantation upon intensive care unit (ICU) arrival and at 12 and 24 hours later (T1, T2, and T3, respectively). We also compared the duration of mechanical ventilatory support and ICU stay. RESULTS: The PO2/FiO2 ratio was significantly better in the P than EC group at T1, T2, and T3. The duration of mechanical ventilatory support and ICU stay were lower also in P group, whereas age, sex, aetiology of lung disease, donor, PaO2/FiO2 ratio, and ischemia time did not show differences between the 2 groups. CONCLUSIONS: Our data on graft function tend to confirm better graft preservation using the P preservation solution.

Laparoscopic approach to incisional hernia.

BACKGROUND: After more than 8 years of working in the field, we thought it would be interesting to evaluate our experience in the laparoscopic repair of abdominal wall hernias, focusing attention on the lessons learned with time. METHODS: From January 1994 to November of 2000, a total of 270 patients with abdominal wall hernias were treated in our center using the laparoscopic approach. The data collected and analyzed were preoperative evaluation, operative findings, early and long-term complications, and recurrences. RESULTS: The mean follow-up time was 44 months, mean surgical time was 85 min, and mean hospital stay was 1.5 days. The average number of abdominal wall defects was 4.8 per patient. There were 9 (3.3%) small bowel perforations. Conversion to open surgery was required in 1 case (0.3%). Minor early postoperative complications occurred in 38 patients (14.07%). Twenty patients (7.4%) developed persistent postoperative abdominal pain. There was 1 case (0.3%) of small bowel incarceration through the mesh border and another case (0.3%) of small bowel leakage due to ischemia and subsequent peritonitis. The relapse rate was 4.4% (12 cases). CONCLUSION: The laparoscopic approach is a valuable option in the management of abdominal wall hernias, but it requires experience in laparoscopic surgery and there is a specific learning curve for the technique.

ERCP's role in the management of acute biliary-pancreatic pathology in the laparoscopic era.

OBJECTIVES: Laparoscopic cholecystectomy (LC) combined with endoscopic retrograde cholangiopancreatography (ERCP) has been widely used in the management of the acute biliopancreatic pathology. Nevertheless, controversy remains about the appropriate timing for retrograde cholangiopancreatography. METHODS: A retrospective study was undertaken on a consecutive series of 117 patients with acute biliary-pancreatic pathology, who underwent laparoscopic cholecystectomy between April 1995 and April 1999. Criteria for preoperative endoscopic retrograde cholangiopancreatography were defined, and the patients were divided into 3 groups based on the presence or absence of a preoperative retrograde cholangiopancreatography indication: (1) ERCP+LC group: patients with retrograde cholangiopancreatography indicated and performed (n = 30); (2) LC group: patients without retrograde cholangiopancreatography criteria treated only by LC (n = 47); (3) LC-ERCP group: patients with retrograde cholangiopancreatography criteria but not performed (n = 40). RESULTS: The groups were similar in age, sex, ASA, and clinical diagnosis. No statistical differences occurred in operative times (73.8 min, 68 min, 67 min), major complications (3.3%, 4.25%, 12.5%), and mean postoperative stay (3.7 +/- 4; 4.7 +/- 2; 5.7 +/- 2). Postoperative retrograde cholangiopancreatography had to be used, respectively, in 0%, 10.6%, and 7.5%. The best predictive criteria for common bile duct pathology were choledocholithiasis on an ultrasound scan and the presence of cholangitis. The other criteria tested had a low predictive value. CONCLUSIONS: Preoperative endoscopic retrograde cholangiopancreatography followed by early laparoscopic cholecystectomy can be performed safely in acute biliary-pancreatic pathology, avoiding 2-stage treatment of these patients and minimizing hospital stay and inconvenience to the patients. Nevertheless, this therapeutic/diagnostic tool must be used selectively.
