RESUMEN

Tobacco use during pregnancy is the main avoidable cause of morbidity and mortality both for pregnant women and their offspring. Between 12 and 22% of pregnant women in industrialized countries smoke during pregnancy, and 13% are unable to stop smoking. Pregnancy is considered an ideal opportunity to intervene and control tobacco use among smokers and their families. However, pregnant women experience barriers to quitting smoking, including social stigma and fear of being judged. Thus, it is necessary to develop interventions for smoking cessation adapted for pregnant women. This paper presents a qualitative study protocol to assess the barriers and facilitators of smoking cessation during pregnancy that female smokers encounter or perceive. It consists of a series of focus groups and individual interviews with female smokers who have been pregnant within the last five years. Participants will be recruited from the Sexual and Reproductive Health Care Services of the Camp de Tarragona. A group of 5-10 women who have been pregnant and tried to quit smoking over the last 5 years will be selected. The data will be collected by means of semistructured interviews. All interviews will be transcribed verbatim, coded and synthesized into categories and main themes. Thematic analysis will be conducted employing an iterative and reflexive approach. The results of this study will offer new perspectives on smoking interventions for pregnant women and enhance our comprehension of the main barriers to and facilitators of smoking cessation during pregnancy. This will contribute to the adaptation of the Tobbstop app, originally designed for the general public, to suit the needs of pregnant women. Consequently, the creation of targeted interventions will positively influence the health outcomes of both pregnant women and newborns. Trial registration: Clinicaltrials.gov ID: NCT05222958. The trial was registered 3 February 2022, at https://clinicaltrials.gov/ct2/show/NCT05222958.

RESUMEN

BACKGROUND: Clinical benefits using the 23-valent pneumococcal polysaccharide vaccine (PPsV23) or the 13-valent pneumococcal conjugate vaccine (PCV13) in adults are controversial. This study investigated clinical effectiveness for both PPsV23 and PCV13 in preventing pneumonia among middle-aged and older adults. METHODS: Population-based cohort study involving 2,025,730 persons ≥50 years in Catalonia, Spain, who were prospectively followed between 01/01/2015 and 31/12/2016. Primary outcomes were hospitalisation from pneumococcal or all-cause pneumonia and main explanatory variable was PCV13/PPsV23 vaccination status. Multivariable Cox regression models were used to estimate vaccination effectiveness adjusted for age and baseline-risk conditions. RESULTS: Cohort members were followed for 3,897,151 person-years (17,496 PCV13 vaccinated and 1,551,502 PPsV23 vaccinated), observing 3259 pneumococcal pneumonias (63 in PCV13 vaccinated, 2243 in PPsV23 vaccinated) and 24,079 all-cause pneumonias (566 in PCV13 vaccinated, 17,508 in PPsV23 vaccinated). Global incidence rates (per 100,000 person-years) were 83.6 for pneumococcal pneumonia (360.1 in PCV13 vaccinated, 144.6 in PPsV23 vaccinated) and 617.9 for all-cause pneumonia (3235.0 in PCV13 vaccinated, 1128.5 in PPsV23 vaccinated). In the multivariable analyses, the PCV13 appeared significantly associated with an increased risk of pneumococcal pneumonia (hazard ratio [HR]: 1.52; 95% confidence interval [CI]: 1.17-1.97; p = 0.002) and all-cause pneumonia (HR: 1.76; 95% CI: 1.61-1.92; p < 0.001) whereas the PPsV23 did not alter the risk of pneumococcal pneumonia (HR: 1.08; 95% CI: 0.98-1.19; p = 0.132) and slightly increased the risk of all-cause pneumonia (HR: 1.17; 95% CI: 1.13-1.21; p < 0.001). In stratified analyses focused on specific target population subgroups (i.e., elderly people, at-risk and high-risk individuals), protective effects of vaccination did not emerge either. CONCLUSION: Data does not support clinical benefits from pneumococcal vaccination (nor PCV13 neither PPsV23) against pneumonia among Catalonian adults in the current era of universal PCV's childhood immunisation.

RESUMEN

BackgroundRecent published data on pneumococcal vaccination coverages among adults are scarce.AimTo update on pneumococcal vaccination uptakes among middle-aged and older adults in Catalonia.MethodsWe conducted a population-based retrospective observational study including 2,057,656 individuals ≥ 50 years old assigned to primary care centres managed by the Catalonian Health Institute on 1 January 2017 (date of data collection). An institutional clinical research database (SIDIAP) was used to classify persons by vaccination status for both 23-valent pneumococcal polysaccharide (PPsV23) and 13-valent pneumococcal conjugate (PCV13) vaccines, as well as to identify underlying risk conditions.ResultsOverall, 796,879 individuals (38.7%) had received PPsV23 and 13,607 (0.7%) PCV13. PPsV23 coverage increased with age: 9.2% (95,409/1,039,872) in 50-64 year olds, 63.1% (434,408/688,786) in 65-79 year olds and 81.2% (267,062/328,998) in ≥ 80 year olds (p < 0.001). PCV13 coverage also increased with age, although percentages were smaller in all age strata (4,250/1,039,872: 0.4%; 6,005/688,786: 0.9% and 3,352/328,998: 1.0%, respectively; p < 0.001). By sex, no substantial coverage differences were observed. Considering publically funded target groups for PPsV23 vaccination in Catalonia (i.e. < 65 year olds with at least one risk factor, plus all adults aged ≥ 65 years), PPsV23 coverage reached 52.8% (771,722/1,462,261) in our study population. Regarding PCV13 publicly funded targets (i.e. all-age immunocompromised persons), PCV13 coverage was 3.3% (6,617/202,348). By risk conditions, the highest PPsV23 coverage appeared in congestive heart failure (51,909/63,596; 81.6%), chronic renal disease (122,791/158,726; 77.4%) and chronic bronchitis/emphysema (96,453/132,306; 72.9%). Maximum PCV13 coverage appeared in cirrhosis (294/7,957; 3.7%), chronic renal disease (5,633/158,726; 3.5%) and chronic bronchitis/emphysema (2,859/132,306; 2.2%).ConclusionPneumococcal vaccination coverages in Catalonian adults are suboptimal, especially for PCV13.

RESUMEN

BACKGROUND: Population-based data about the epidemiology of acute myocardial infarction is limited. This study investigated incidence and mortality of acute myocardial infarction in older adults with specific underlying chronic conditions and evaluated the influence of these conditions in developing acute myocardial infarction. DESIGN AND METHODS: This was a population-based cohort study involving 27,204 individuals ≥ 60 years of age in Tarragona (Catalonia, Spain). Data on all cases of hospitalised acute myocardial infarction were collected from 1 December 2008-30 November 2011. Incidence rates and 30-day mortality were estimated according to age, sex, chronic illnesses and underlying conditions. Multivariable Cox regression analysis was used to calculate hazard ratios and to estimate the association between baseline conditions and risk of developing acute myocardial infarction. RESULTS: The incidence of acute myocardial infarction was 475 per 100,000 person-years. Maximum rates appeared among individuals with history of coronary artery disease (2839 per 100,000), chronic severe nephropathy (1407 per 100,000), atrial fibrillation (1226 per 100,000), chronic heart disease (1149 per 100,000), history of stroke (1147 per 100,000) and diabetes mellitus (914 per 100,000). Thirty-day mortality was 15.3% overall, reaching 31.6% among patients over 80 years. In the multivariable analysis, history of coronary artery disease, age > 70 years, sex male, chronic heart disease, history of stroke, atrial fibrillation, diabetes mellitus and hypertension emerged as significantly associated with an increased risk of acute myocardial infarction. CONCLUSIONS: The incidence and mortality of acute myocardial infarction remain considerable in our setting. Considering classical major risk factors, diabetes mellitus and hypertension were the underlying conditions most strongly associated with an increased risk in our study population.

RESUMEN

BACKGROUND: Benefits using the 13-valent pneumococcal conjugate vaccine (PCV13) in adults are controversial. This study investigated clinical effectiveness of PCV13 vaccination in preventing hospitalisation from pneumonia among middle-aged and older adults. METHODS: Population-based cohort study involving 2,025,730 individuals ≥50 years in Catalonia, Spain, who were prospectively followed from 01/01/2015 to 31/12/2015. Primary outcomes were hospitalisation for pneumococcal or all-cause pneumonia and death from any cause. Cox regression models were used to evaluate the association between PCV13 vaccination and the risk of each outcome, adjusting for age, sex and major comorbidities/underlying risk conditions. RESULTS: Cohort members were observed for a total of 1,990,701 person-years, of which 6912 person-years were PCV13 vaccinated. Overall, crude incidence rates (per 100,000 person-years) were 82.8 (95% confidence interval [CI]: 77.7-88.1) for pneumococcal pneumonia, 637.9 (95% CI: 599.0-678.7) for all-cause pneumonia and 2367.2 (95% CI: 2222.8-2518.7) for all-cause death. After multivariable adjustments we found that the PCV13 vaccination did not alter significantly the risk of pneumococcal pneumonia (multivariable-adjusted hazard ratio [mHR]: 1.17; 95% CI: 0.75-1.83; p = 0.493) and all-cause death (mHR: 1.07; 95% CI: 0.97-1.18; p = 0.190), although it remained significantly associated with an increased risk of all-cause pneumonia (mHR: 1.69; 95% CI: 1.48-1.94; p < 0.001). In stratified analyses focused on middle-aged or elderly persons and immunocompromised or immunocompetent subjects, PCV13 vaccination did not appear effective either. CONCLUSION: Our data does not support clinical benefits of PCV13 vaccination against pneumonia among adults in Catalonia. It must be closely monitored in future studies involving more vaccinated person-time at-observation.

RESUMEN

OBJECTIVES: To know antipneumococcal vaccination coverages among Catalonian adults and evaluate the adequacy of vaccine use according to 3 distinct current vaccination guidelines. DESIGN: Population-based cross-sectional study. SETTING: Primary Health Care. Catalonia, Spain. PARTICIPANTS: A total of 2,033,465 individuals≥50 years-old registered in the Catalonian Health Institute. MAIN MEASUREMENTS: Vaccination status for the 23-valent pneumococcal polysaccharide vaccine (PPV23) and/or the 13-valent pneumococcal conjugate vaccine (PCV13) was revised at 1/01/2015. Adequacy of vaccination status was determined according to 3 distinct vaccination recommendation guidelines: Spanish Ministry of Health (basically coinciding with Catalonian Health Institute's recommendations), Spanish Society of Family Physicians (semFYC) and Centers for Disease Control and Prevention (CDC). RESULTS: Overall, 789,098 (38.8%) persons had received PPV23 and 5,031 (0.2%) had received PCV13. PPV23 coverage largely increased with increasing age (4.8% in 50-59 years, 35.5% in 60-69 years, 71.9% in 70-79 years and 79.5% in≥80 years; P<.001), whereas PCV13 coverage was very small in all age groups. Considering the 3 analysed vaccine guidelines a 46.1% of the overall study population were adequacy vaccinated according to Spanish Ministry's recommendations, 19.3% according to semFYC's recommendations and 4.6% according to CDC's recommendations. CONCLUSION: PPV23 coverage among Catalonian adults may be considered as intermediate, but PCV13 coverage is very small. The institutional recommendations (Spanish Ministry) are more followed than corporative (semFYC) or less local (CDC) recommendations in clinical practice.

RESUMEN

OBJECTIVE: Published data about prevalence of distinct risk condictions for pneumococcal disease is scarce. This study investigated the prevalence of distinct risk conditions for pneumococal disease in Catalonian adults and stimated the potential size of target population for pneumococcal vaccination in Catalonia and Spain. METHODS: Cross-sectional population-based study that included 2,033,465 individuals older than 49 years-old assigned to the Catalonian Health Institute (Catalonia, Spain) at 01/01/2015. The Catalonian Health Institute Information System for the Development of Research in Primary Care (SIDIAP) was used to identify comorbidities and/or underlying conditions in each subject and establish potential target population for pneumococcal vaccination on the basis of their risk for suffering pneumococcal infections: 1) immunocompromised subjects; 2) immunocompetents subjects with any risk condition; 3) immunocompetents subjects without risk conditions. RESULTS: Of the 2,033,465 study subjects, 1,053,155 (51.8%) had no risk conditions, 649,014 (31.9%) had one risk condition and 331,296 (16.3%) had multiple risk conditions (11.4% in 50-64 years vs 21.2% in people older than 65 years, p smaller than 0.001; 21.8% in men vs 11.6% in women, p smaller than 0.001). Overall, 176,600 (8.7%) and 803,710 (39.5%) were classified in risk stratum 1 and 2, respectively. According to distinct risk strata considered, the target population for pneumococcal vaccination varied between 0.2-1.9 million in Catalonia and 1.5-2.3 million in Spain. CONCLUSIONS: In our setting, almost fifty percent of people ≥50 years have at least one risk condition to suffert pneumococcal disease. Adult population susceptible for pneumococal vaccination largely varies depending on the risk stratum considered as targeted people for pneumococcal vaccination.


OBJETIVO: La información publicada sobre la prevalencia de los distintos factores o condiciones de riesgo para padecer enfermedad neumocócica es escasa. El objetivo de la investigación fue describir en Cataluña la prevalencia de factores de riesgo de padecer enfermedad neumocócica en personas de 50 años o más y estimar el tamaño teórico de la población diana necesario para incluir la vacunación antineumocócica en Cataluña y España. METODOS: Estudio transversal que incluyó a 2.033.465 personas de 50 años y más asignadas al Institut Català de la Salut a 01/01/2015. Se utilizó el Sistema de Información para el Desarrollo de la Investigación en Atención Primaria de Cataluña (SIDIAP) para identificar las comorbilidades o condiciones de riesgo en cada sujeto y establecer su clasificación en la población potencialmente susceptible de ser vacunada en base a su riesgo de sufrir enfermedad neumocócica: 1) inmunocomprometidos; 2) inmunocompetentes con alguna condición de riesgo; 3) inmunocompetentes sin condiciones de riesgo. RESULTADOS: De las 2.033.465 personas estudiadas, 1.053.155 (51,8%) no tenían ninguna condición de riesgo, 649.014 (31,9%) tenían una y 331.296 (16,3%) tenían múltiples (11,4% en 50-64 años vs 21,2% en ≥65 años, p menor de 0,001; 21,8% en hombres vs 11,6% en mujeres, p menor de 0,001). En total, 176.600 (8,7%) fueron clasificadas en el estrato de riesgo 1 y 803.710 (39,5%) en el 2. Según los estratos de riesgo considerados, la población susceptible de vacunación antineumocócica se situaría entre 0,2-1,9 millones en Cataluña y 1,5-12,3 millones en España. CONCLUSIONES: En nuestro ámbito, casi la mitad de la población ≥50 años tiene alguna condición de riesgo para padecer enfermedad neumocócica. El teórico tamaño de la población adulta susceptible de recibir la vacuna antineumocócica varía enormemente en función de los estratos de riesgo considerados como diana para la vacunación.

RESUMEN

There is scarce data about pneumococcal vaccination coverages among adults in recent years. We investigated current pneumococcal vaccination coverages in Catalonia, Spain, with a cross-sectional population-based study including 2,033,465 individuals aged 50 y or older assigned to the Catalonian Health Institute at 01/01/2015 (date of survey). A previously validated institutional research clinical Database was used to classify study subjects by their vaccination status for both 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13), to identify comorbidities and underlying conditions, and establish the risk stratum of each individual: High risk stratum: functional or anatomic asplenia, cochlear implants, CSF leaks, or immunocompromising conditions; medium risk stratum: immunocompetent persons with history of chronic cardiac or respiratory disease, liver disease, diabetes mellitus, alcoholism and/or smoking; low risk stratum: persons without high or medium risk conditions. Of the total 2,033,465 study population, an amount of 789,098 (38.8%) had received PPVS23, whereas 5031 (0.2%) had received PCV13. PPSV23 coverages increased largely with increasing age: 4.8% in 50-59 y vs 35.5% in 60-69 y vs 71.9% in 70-79 y vs 79.5% in 80 y or older; p < 0.001). PCV13 coverages also increased with age, although they were very low in all age groups. PPSV23 coverages were 59.2% in high risk stratum, 48.3% in medium risk stratum and 28.1% in low risk stratum (p < 0.001). For the PCV13, uptakes were 1.2%, 0.3% and 0.1% in high, medium and low stratum, respectively (p < 0.001). In conclusion, pneumococcal vaccination coverages in Catalonian adults are not optimal, being especially small for the PCV13 (even in high-risk subjects).

RESUMEN

Background: This study investigated the burden (incidence, mortality and serotype distribution) of pneumococcal pneumonia among older adults in the region of Tarragona (Spain). Methods: Population-based cohort study involving 27,204 individuals ≥60 years in Tarragonès county (Southern Catalonia), who were prospectively followed between 01/12/2008 and 30/11/2011. Bacteremic and nonbacteremic (positive sputum culture and/or urinary antigen test) pneumococcal pneumonias were recruited. Results: A total of 125 pneumococcal pneumonias (16 bacteremic and 109 nonbacteremic) was observed. Incidence rates (per 1000 person-years) were 0.21 (95% confidence interval [CI]: 0.13-0.35) for bacteremic cases and 1.45 (95% CI: 1.20-1.75) for nonbacteremic cases. Case-fatality rate was 10.4% (12.5% in bacteremic and 10.1% in nonbacteremic cases). Five serotypes (types 3, 6C, 19A, 22F and 35B) were the most common serotypes, accounting for 64.3% of overall isolated serotypes. 73.1% of cases were due to the strains included in the 23-valent vaccine whereas 53.6% were due to the strains included in the 13-valent vaccine. Conclusion: The burden of pneumococcal pneumonia remains considerable (especially among oldest people and nursing-home residents) despite a publicly funded anti-pneumococcal vaccination program operative for several years (AU)


Fundamento: Este estudio analiza la epidemiología (incidencia, letalidad y distribución de serotipos) de la neumonía neumocócica en adultos mayores de Tarragona. Métodos: Cohorte de base poblacional que incluyó 27.204 individuos ≥ 60 años en la comarca del Tarragonès, con seguimiento prospectivo entre 1-12-2008 y 30-11-2011 y selección de todos los casos de neumonía neumocócica bacteriémica y no-bacteriémica (cultivo de esputo y/o antigenuria positiva). Resultados: Se observaron 125 neumonías neumocócicas (16 bacteriémicas y 109 no bacteriémicas). Las tasas de incidencia (por 1.000 personas-año) fueron 0,21 (intervalo de confianza [IC] 95%: 0,13-0,35) para casos bacteriémicos y 1,45 (IC 95%: 1,20-1,75) para casos no bacteriémicos. La letalidad global fue del 10,4% (12,5% en casos bacteriémicos y 10,1% en no bacteriémicos). Cinco serotipos (3, 6C, 19A, 22F y 35B) fueron los más comunes, representando un 64,3% del total de serotipos aislados. Un 73,1% de los casos fueron debidos a serotipos incluidos en la vacuna 23-valente, mientras que un 53,6% fueron debidos a serotipos incluidos en la vacuna 13-valente. Conclusión: La incidencia de neumonía neumocócica es considerable (especialmente en personas mayores y/o institucionalizadas) a pesar del programa público de vacunación antineumocócica implementado desde hace años (AU)

RESUMEN

BACKGROUND: This study investigated the burden (incidence, mortality and serotype distribution) of pneumococcal pneumonia among older adults in the region of Tarragona (Spain). METHODS: Population-based cohort study involving 27,204 individuals ≥60 years in Tarragonès county (Southern Catalonia), who were prospectively followed between 01/12/2008 and 30/11/2011. Bacteremic and nonbacteremic (positive sputum culture and/or urinary antigen test) pneumococcal pneumonias were recruited. RESULTS: A total of 125 pneumococcal pneumonias (16 bacteremic and 109 nonbacteremic) was observed. Incidence rates (per 1000 person-years) were 0.21 (95% confidence interval [CI]: 0.13-0.35) for bacteremic cases and 1.45 (95% CI: 1.20-1.75) for nonbacteremic cases. Case-fatality rate was 10.4% (12.5% in bacteremic and 10.1% in nonbacteremic cases). Five serotypes (types 3, 6C, 19A, 22F and 35B) were the most common serotypes, accounting for 64.3% of overall isolated serotypes. 73.1% of cases were due to the strains included in the 23-valent vaccine whereas 53.6% were due to the strains included in the 13-valent vaccine. CONCLUSION: The burden of pneumococcal pneumonia remains considerable (especially among oldest people and nursing-home residents) despite a publicly funded anti-pneumococcal vaccination program operative for several years.

RESUMEN

Fundamentos. La información procedente de datos de base poblacional sobre la epidemiología del infarto agudo de miocardio es limitada. Este estudio analizó la incidencia y mortalidad por infarto en la población general mayor de 60 años del área sanitaria de Tarragona. Métodos. Estudio de cohortes que incluyó a 27.204 personas ≥60 años adscritas a 9 Áreas Básicas de Salud en la comarca del Tarragonés. Se realizó un seguimiento prospectivo durante 3 años, en los que se registraron todos los episodios de infarto diagnosticados entre los miembros de la cohorte desde 01/12/2008 a 30/11/2011. Se incluyeron exclusivamente los episodios con diagnóstico validado tras revisión de la historia clínica, se excluyeron los casos sin confirmación electrocardiográfica y por biomarcadores. Resultados: Hubo un total de 359 episodios confirmados de infarto, lo cual supuso una incidencia de 475 episodios por 100.000 personas-año (IC 95%: 428-527). La incidencia en hombres fue de 681 por 100.000 y en mujeres de 311 (p<0,001). Por edad fue 277 en el grupo de 60-69, 632 en el de 70-79 y 690 por 100.000 en los sujetos de ≥80 años (p<0,001). La incidencia en las personas con diagnóstico previo de cardiopatía isquémica fue de 2.844 casos por 100.000 personas-año. La mortalidad a los 30 días tras el diagnóstico alcanzó el 15,3%, en hombres 14,9% y en mujeres 16,0% (p=0,776). Conclusiones: La incidencia fue 2,2 veces mayor en hombres que en mujeres y aumentó considerablemente con la edad. También fue superior entre las personas con diagnóstico previo de cardiopatía isquémica. La mortalidad fue ligeramente más baja en hombres que en mujeres (AU)


Background: Population-based data available about the epidemiology of acute myocardial infarction is limited. This study investigated incidence and mortality from infarction among the general population over 60 years in Tarragona. Methods: Cohort study that included 27,204 individuals ≥60 years assigned to nine Primary Care Centers in the Tarragones county (Catalonia, Spain), who were prospectively followed between 01/12/2008 and 30/11/2011. During follow-up, all presumptive episodes of infarction were recruited among cohort members, but only confirmed cases (electrocardiogram and biomarkers confirmation) were included. Results: There were an amount of 359 confirmed episodes of infarction, which means a global incidence rate of 475 episodes per 100,000 person-years (95% CI: 428-527). Incidence was 681 in men and 311in women (p<0.001). According to age, incidence was 277 in 60-69, 632 in 70-79 and 690 per 100,000 in ≥80 years (p<0.001). Incidence was 2,844 cases per 100,000 person-years among those persons whom had history of prior coronary artery disease. Overall 30-day mortality rate was 15.3%, in male 14.9% and in female 16.0% (p=0.776). Conclusion: Incidence was 2.2 times higher in men than in woman and increased considerable by age. It was greater among patients with prior history of coronary artery disease. Mortality was slightly lower in men than in women (AU)

RESUMEN

BACKGROUND: Conflicting results have been recently reported evaluating the relationship between pneumococcal vaccination and the risk of thrombotic vascular events. This study assessed the clinical effectiveness of the 23-valent polysaccharide pneumococcal vaccine (PPV23) against acute myocardial infarction and ischaemic stroke in older adults. METHODS: Population-based prospective cohort study conducted from December 1, 2008 until November 30, 2009, including all individuals ≥ 60 years-old assigned to nine Primary Care Centres in Tarragona, Spain (N = 27,204 individuals). Primary outcomes were hospitalisation for acute myocardial infarction and/or ischaemic stroke. All cases were validated by checking clinical records. The association between pneumococcal vaccination and the risk of each outcome was evaluated by Multivariable Cox proportional-hazard models (adjusted by age, sex, influenza vaccine status, presence of comorbidities and cardiovascular risk factors). RESULTS: Cohort members were followed for a total of 26,444 person-years, of which 34% were for vaccinated subjects. Overall incidence rates (per 1000 person-years) were 4.9 for myocardial infarction and 4.6 for ischaemic stroke. In the multivariable analysis, vaccination was associated with a marginally significant 35% lower risk of stroke (hazard ratio [HR]: 0.65; 95% confidence interval [CI]: 0.42-0.99; p = 0.046). We found no evidence for an association between pneumococcal vaccination and reduced risk of myocardial infarction (HR: 0.83; 95% CI: 0.56-1.22; p = 0.347). CONCLUSIONS: Our data supports a benefit of PPV23 against ischaemic stroke among the general population over 60 years, suggesting a possible protective role of pneumococcal vaccination against some acute thrombotic events.
