Alarming incidence of reinfections after treatment for Chlamydia trachomatis and gonorrhoea: Can we predict and prevent them?

BackgroundChlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections are a public health problem, worsened by frequent reinfections, whose incidence rate is not known in Spain. The objective of this study is to estimate in patients diagnosed with NG, CT or mixed infection (NG and CT): (1) the incidence of reinfections by the same microorganism, (2) the total incidence of Sexually Transmitted Infections (STI), both by the same microorganism and by infections other than the initial one, and (3) to identify predictors of reinfection.MethodsObservational prospective case series involving 986 patients with CT and/or NG at specialized STI clinics in Biscay (Spain) between 2016 and 2019.ResultsThe six month cumulative incidence of reinfection by the same microorganism was 17.24% (CI95%: 14.9–19.7) and 24.65% (CI95%: 21.9–27.4) for any STI (reinfection or other). Being an immigrant (OR = 1.8; CI95%: 1.3–2.6), men who have sex with men (OR = 1.8; CI95%: 1.3–2.6), number of sexual partners (OR = 4.3; CI95%: 2.7–6.8 for more than 5 partners), having a new partner (OR = 1.7; CI95%: 1.08–2.6), not always using a condom (OR = 1.4; CI95%: 1.02–1.9) and consumption of alcohol prior to sex (OR = 3.8; CI95%: 1.5–9.5) were associated with reinfection by any STI.ConclusionThese characteristics allow doctors to identify patients in whom to prioritize short-term rescreening for repeated infections with any STIs after initial treatment for NG or CT.     

[Translated article] Lung Cancer Screening: Survival in an Extensive Early Detection Program in Spain (I-ELCAP)

IntroductionLung cancer (LC) is usually diagnosed at advanced stages with only a 12% 5-year survival. Trials as NLST and NELSON show a mortality decrease, which justifies implementation of lung cancer screening in risk population. Our objective was to show survival results of the largest LC screening program in Spain with low dosage computed tomography (LDCT).MethodsClinical records from International Early Lung Cancer Detection Program (IELCAP) at Valencia, Spain were analyzed. This program recruited volunteers, ever-smokers aged 40–80 years, since 2008. Results are compared to those from other similar sizeable programs.ResultsA total of 8278 participants were screened with at least two-rounds until November 2020. A mean of 6 annual screening rounds were performed. We detected 239 tumors along 12-year follow-up. Adenocarcinoma was the most common histology, being 61.3% at stage I. The lung cancer prevalence and incidence proportion was 1.5% and 1.4%, respectively with an annual detection rate of 0.17. One-year survival and 10-year survival were 90% and 80.1%, respectively. Adherence was 96.84%.ConclusionLargest lung cancer screening in Spain shows that survival is improved when is performed in multidisciplinary team experienced in management of LC, and is comparable to similar screening programs.     

Infecciones de transmisión sexual en el contexto de una agresión sexual

Sexual violence is a worldwide problem with an impact on health that encompasses medical, legal and psychological aspects. Therefore the management of these patients must be multidisciplinary, and action protocols are compulsory. People who are victims of a sexual assault (SA) are at high risk of acquiring a sexually transmitted infection (STI), which must be prevented, diagnosed, treated and followed up post treatment, according to the established action protocol to prevent potential complications.     

Validity for use in research on vascular diseases of the SIDIAP (Information System for the Development of Research in Primary Care): the EMMA study

Introduction and objectives

Information in primary care databases can be useful in research, but the validity of these data needs to be evaluated. We sought to analyze the validity of the data used in the EMMA study based on data from the Information System for the Development of Research in Primary Care.

Methods

We compared the prevalence of cardiovascular risk factors observed in EMMA–hypertension, diabetes, hypercholesterolemia (and its treatments), obesity, and smoking–with equivalent data from the Registre Gironí del Cor (REGICOR), a population-based study that uses standardized methodology, in 2000. We also compared the incidence rates of vascular diseases and its association with these risk factors in a 5-year follow-up.

Results

We analyzed data from 34 823 participants included in EMMA and 2540 REGICOR2000 study participants aged 35 to 74. The prevalence of risk factors did not differ significantly between the 2 studies, except for the prevalence of former smokers in men, which was higher in REGICOR2000 (24.7% [95% confidence interval, 23.9%-25.5%] vs 30.1% [95% confidence interval, 27.1%-33.1%]), and the proportion of patients with lipid-lowering and antihypertensive therapy, which was higher in EMMA (46.9% vs 32.7% and 8.7% vs 6.3%, respectively). There were no differences between the 2 studies when comparing the incidence of vascular diseases (2.1% in both studies in men and 1.18% [95% confidence interval, 0.7%-1.7%] in REGICOR2000 vs 0.75% [95% confidence interval, 0.64%-0.87%] in EMMA in women) and its association with risk factors.

Conclusions

The prevalence of cardiovascular risk factors and their association with the incidence of vascular disease observed in the EMMA study are consistent with those observed in an epidemiological population-based study with a standardized methodology.Full English text available from:www.revespcardiol.org     

Analyzing the coronary heart disease mortality decline in a Mediterranean population: Spain 1988-2005

Introduction and objectives

To examine the extent to which the decrease in coronary heart disease mortality rates in Spain between 1988 and 2005 could be explained by changes in cardiovascular risk factors and by the use of medical and surgical treatments.

Methods

We used the previously validated IMPACT model to examine the contributions of exposure factors (risk factors and treatments) to the main outcome, changes in the mortality rates of death from coronary heart disease, among adults 35 to 74 years of age. Main data sources included official mortality statistics, results of longitudinal studies, national surveys, randomized controlled trials, and meta-analyses. The difference between observed and expected coronary heart disease deaths in 2005 was then partitioned between treatments and risk factors.

Results

From 1988 to 2005, the age-adjusted coronary heart disease mortality rates fell by almost 40%, resulting in 8530 fewer coronary heart disease deaths in 2005. Approximately 47% of the fall in deaths was attributed to treatments. The major treatment contributions came from initial therapy for acute coronary syndromes (11%), secondary prevention (10%), and heart failure (9%).About 50% of the fall in mortality was attributed to changes in risk factors. The largest mortality benefit came from changes in total cholesterol (about 31% of the mortality fall) and in systolic blood pressure (about 15%). However, some substantial gender differences were observed in risk factor trends with an increase in diabetes and obesity in men and an increase in smoking in young women. These generated additional deaths.

Conclusions

Approximately half of the coronary heart disease mortality fall in Spain was attributable to reductions in major risk factors, and half to evidence-based therapies. These results increase understanding of past trends and will help to inform planning for future prevention and treatment strategies in low-risk populations.Full English text available from: www.revespcardiol.org     

Epidemiology,prevention and control of pertussis in Spain: New vaccination strategies for lifelong protection

Pertussis is a highly contagious, vaccine-preventable respiratory tract infection, with high morbidity and mortality and a particularly severe effect on newborns and infants under 2 months. The first pertussis vaccines were introduced in the 1940s. Since 1980, however, the incidence of cases has risen despite the extensive vaccination programmes and antibiotic adjuvant treatments available. Transition from the use of whole-cell vaccines to acellular vaccines and the antigenic modifications of Bordetella pertussis have contributed, among other factors, to a reduction in vaccine-acquired immunity and reemergence of the disease. Today, there are still unmet needs not covered by conventional prevention measures and existing antibiotic treatments. This review aims to update the available data, and to discuss which vaccine strategies might contribute to better disease control and prevention.     

Identification of a new variant of Chlamydia trachomatis in Mexico

Introduction

Chlamydia trachomatis is one of the main etiological agents of sexually transmitted infections worldwide. In 2006, a Swedish variant of C. trachomatis (Swedish-nvCT), which has a deletion of 377 bp in the plasmid, was reported. In Latin America, Swedish-nvCT infections have not been reported. We investigated the presence of Swedish-nvCT in women with infertility in Mexico.

Executive summary of the Consensus Statement of the Transplant Infection Study Group (GESITRA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) and the National Transplant Organization (ONT) on the Selection Criteria of Donors of Solid Organs in relation to Infectious Diseases

The immunosuppressive treatment that recipients receive from a solid organ transplantation hinders the defensive response to infection. Its transmission from the donor can cause dysfunction or loss of the graft and even death of the recipient if proper preventive measures are not established. This potential risk should be thoroughly evaluated to minimise the risk of infection transmission from donor to recipient, especially with organ transplantation from donors with infections, without increasing graft dysfunction and morbidity and mortality in the recipient. This document aims to review current knowledge about infection screening in potential donors and offer clinical and microbiological recommendations about the use of organs from donors with infection based on available scientific evidence.     

Reactivation of Hepatitis B virus in kidney transplant recipients with previous clinically resolved infection: A single-center experience

Background

Hepatitis B virus (HBV) reactivation in kidney transplant recipients (KTR) involves important morbidity and mortality. Despite being more common in patients who are HBsAg-positive, it may occur in patients with clinically resolved infection (HBsAg-negative and anti-HBc-positive), in whom the presence of the protective anti-HB antibody is thought to decrease the risk of reactivation. Data regarding reactivation rates in this population are scarce.

Predictive factors for inadequate bowel cleansing in colon capsule endoscopy

Background and aimsAchieving adequate bowel cleansing is of utmost importance for the efficiency of colon capsule endoscopy (CCE). However, information about predictive factors is lacking. The aim of this study was to assess the predictive factors of poor bowel cleansing in the CCE setting.MethodsIn this observational study, 126 patients who underwent CCE at two tertiary care hospitals were included between June 2017 and January 2020. Participants prepared for bowel cleansing with a 1-day clear liquid diet, a 4-L split-dose polyethylene glycol regimen and boosters with sodium phosphate, sodium amidotrizoate and meglumine amidotrizoate. Domperidone tablets and bisacodyl suppositories were administered when needed. Overall and per-segment bowel cleansing was evaluated using a CCE cleansing score. Simple and multiple logistic regression analysis were carried out to assess poor bowel cleansing and excretion rate predictors.ResultsOverall bowel cleansing was optimal in 53 patients (50.5%). Optimal per-segment bowel cleansing was achieved as follows: cecum (86 patients; 74.8%), transverse colon (91 patients; 81.3%), distal colon (81 patients; 75%) and rectum (64 patients; 66.7%). In the univariate analysis, elderly (OR, 1.03; 95% CI (1.01–1.076)) and constipation (OR, 3.82; 95% CI (1.50–9.71)) were associated with poor bowel cleansing. In the logistic regression analysis, constipation (OR, 3.77; 95% CI (1.43–10.0)) was associated with poor bowel cleansing. No variables were significantly associated with the CCE device excretion rate.ConclusionOur results suggest that constipation is the most powerful predictor of poor bowel cleansing in the CCE setting. Tailored cleansing protocols should be recommended for these patients.     

Remission in axial spondyloarthritis: Developing a consensus definition

ObjectiveTo reach a consensus on the tools available to evaluate disease activity in patients with axial spondyloarthritis (axSpA), and to develop a consensus definition of remission in axSpA.MethodsA modified Delphi method was used. A scientific committee proposed statements addressing the assessment of axSpA in clinical practice and the definition of remission. The questionnaire was evaluated in 2 rounds by rheumatologists from GRESSER (GRupo de Estudio de ESpondiloartritis de la Sociedad Española de Reumatología).ResultsAfter 2 rounds of evaluation, a panel of 81 rheumatologists reached agreement on 56 out of the 80 proposed items (72.0%). There was agreement that the definition of remission in axSpA should include: disease activity, pain, fatigue, peripheral involvement, extra-articular manifestations, laboratory tests, functional impairment, mobility, quality of life, need for treatment, radiographic progression, and patient and physician global assessments. It is recommended to set a therapeutic goal when starting a treatment. The ideal goal is remission although low disease activity may also be an acceptable alternative. The Ankylosing Spondylitis Disease Activity Score (ASDAS) is the preferred tool to assess disease activity. The panel made a proposal for clinical remission in axSpA based on the ASDAS cut-off value for inactive disease, the absence of extra-articular (acute anterior uveitis, psoriasis, inflammatory bowel disease) and peripheral (arthritis, enthesitis, dactylitis) manifestations, plus normal C-reactive protein levels and absence of radiographic progression.ConclusionThis work offers consensus recommendations and a proposal of clinical remission that may be useful in the management of patients with axSpA.     

Definition of Remission and Disease Activity Assessment in Psoriatic Arthritis: Evidence and Expert-Based Recommendations

ObjectiveWe aimed to reach a consensus on the best instruments to monitor disease activity in patients with psoriatic arthritis (PsA) and to develop a consensus definition of remission.MethodsA modified Delphi approach was used. A scientific committee provided statements addressing the definition of remission and the monitoring of PsA in clinical practice. The questionnaire was evaluated in 2 rounds by rheumatologists with experience in managing PsA patients.ResultsA panel of 77 rheumatologists reached agreement on 62 out of the 86 proposed items (72.0%). The most recommended index for monitoring disease activity was DAPSA (cut-off values: ≤4 for remission and >4–14 for low disease activity ([LDA]), MDA (at least 5/7 criteria). In cases with axial involvement, ASDAS was the preferred index (cut-off values: <1.3 for remission and <2.1 for LDA). BASDAI (cut-off values: ≤2 for remission and ≤4 for LDA) may be used as an alternative. PsAID was the preferred tool to assess disease impact.ConclusionWe propose a definition of remission in PsA as the absence of disease activity evaluated by DAPSA or MDA (ASDAS and/or BASDAI in patients with axial involvement), which would imply absence of signs or symptoms of inflammation, physical well-being, lack of disease impact, and absence of inflammation as measured by biological markers.     

6-Year Risk of Developing Lung Cancer in Spain: Analysis by Autonomous Communities

IntroductionLung cancer screening with low-dose computed tomography (LDCT) has been proposed as a strategy to reduce lung cancer mortality. Since LDCT has side effects there is a need to carefully select the target population for screening programmes. Because in Spain health competences are transferred to the seventeen Autonomous Communities (ACs), the present paper aims to identify individuals at high risk of developing lung cancer in the different ACs.MethodsWe used the 2011–2012 data of the Spanish National Interview Health Survey (n = 21,006) to estimate the proportion of individuals at high risk of developing lung cancer using a 6-year prediction model (PLCO_m2012). This proportion was then extrapolated into absolute figures for the Spanish population, using the population census data of 2018 from the National Institute of Statistics.ResultsThe proportion of individuals aged 50–74 with a risk of lung cancer ≥2% was 9.5% (15.9% in men, 3.5% in women). This proportion ranged from 6.6% in Región de Murcia to 12.7% in Andalucía and 13.0% in Extremadura. When extrapolated to the Spanish population, it was estimated that a total of 1,341,483 individuals may have a 6-year risk of lung cancer ≥2%.ConclusionsThe present study is the first one that evaluated the number of individuals at high risk of developing lung cancer in the different Spanish ACs using a prediction model and selecting people with a 6-year risk ≥2%. Further studies should assess the cost and effectiveness associated to the implementation of a lung cancer screening programme to such population.     

Atlas of axial spondyloarthritis in Spain 2017: Study design and population

ObjectiveAtlas of Axial Spondyloarthritis in Spain 2017 aims to better understand the reality of the patients suffering from this disease from an integrated approach.MethodsThe Atlas 2017 based its results on an extensive cross-sectional patient survey conducted in Spain (2016), validated by a multidisciplinary group of experts on spondyloarthritis.ResultsData from 680 patients with axSpA were obtained, most of them suffered from AS, were HLA-B27 positive, older than 45 years, and live as part of a couple. A large percentage had university studies, were disabled and members of a patient association. Patients reported a diagnostic delay of 8.5 years, high disease activity (BASDAI 5.5 ± 2.2), moderate-important stiffness (61.0%), medium-high functional limitation (74.9%), and psychological distress (GHQ 5.7 ± 4.5). A total of 54.7% reported taking NSAIDs, 28.4% DMARDs, 36.3% biological therapy and 32.2% were not receiving pharmacological treatment.ConclusionsThe Atlas survey data reveals still a long diagnostic delay, high disease activity, psychological distress, while an important proportion could be undertreated.     

Increasing the low residue diet to 3 days does not improve the bowel cleansing in hard to prepare patients: Post hoc analysis of a randomized controlled trial

BackgroundRecent evidence suggests that the number of low residue diet (LRD) days does not influence the bowel cleansing quality in non-selected patients. However, there are not data in the subgroup of patients with risk factors of inadequate bowel cleansing.ObjectiveThe aim of this study was to assess whether a 3-day LRD improved the bowel cleansing quality in patients with risk factors of poor bowel cleansing.Patients and methodsPost hoc analysis of a randomized controlled trial carried out between December 2017 and March 2018 in a tertiary care hospital. Patients with high risk of poor bowel cleansing were selected following a validated score. The patients were randomized to the 1-day LRD or 3-day LRD groups. All patients received a 2-L split-dose of polyethylene glycol plus ascorbic acid. Intention-to-treat (ITT) and per-protocol (PP) analyses were conducted for the main outcome.Results135 patients (1-day LRD group = 67, 3-day LRD = 68) were included. The rate of adequate cleansing quality was not significantly different between the groups in the ITT analysis: 76.1%, 95% CI: [64.6–84.8] vs. 79.4%, 95% CI: [68.2–87.4]; odds ratio (OR) 1.2, 95% CI [0.54–2.73]) or in the PP analysis: 77.3%, 95% CI: [65.7–85.8] vs. 80.3%, 95% CI: [69.0–88.3]; OR 1.2, 95% CI [0.52–2.77]). Compliance with the diet or cleansing solution, satisfaction or difficulties with the LRD and the polyp/adenoma detection rates were not significantly different.ConclusionOur results suggest that 1-day LRD is not inferior to 3-day LRD in patients with risk factors of inadequate bowel cleansing.     

Relationship Among Radiological Measurements of Anterior Mediastinal Fat and Outcomes of Lung Transplantation in Fibrotic Patients

ObjectiveLung transplantation (LT) for pulmonary fibrosis is related to higher mortality than other transplant indications. We aim to assess whether the amount of anterior mediastinal fat (AMF) was associated to early and long-term outcomes in fibrotic patients undergoing LT.MethodsRetrospective analysis of 92 consecutive single lung transplants (SLT) for pulmonary fibrosis over a 10-year period. AMF dimensions were measured on preoperative CT-scan: anteroposterior axis (AP), transverse axis (T), and height (H). AMF volumes (V) were calculated by the formula: AP × T × H × 3.14/6.According to the radiological AMF dimensions, patients were distributed into two groups: low-AMF (V < 20 cm³) and high-AMF (V > 20 cm³), and early and long-term outcomes were compared by univariable and multivariable analyses.ResultsThere were 92 SLT: 73M/19F, 53 ± 11 [14–68] years old. 30-Day mortality (low-AMF vs. high-AMF): 5 (5.4%) vs. 15 (16.3%), p = 0.014. Patients developing primary graft dysfunction within 72 h post-transplant, and those dying within 30 days post-transplant presented higher AMF volumes: 21.1 ± 19.8 vs. 43.3 ± 24.7 cm³ (p = 0.03) and 24.4 ± 24.2 vs. 56.9 ± 63.6 cm³ (p < 0.01) respectively. Overall survival (low-AMF vs. high-AMF) (1, 3, and 5 years): 85%, 81%, 78% vs. 55%, 40%, 33% (p < 0.001).Factors predicting 30-day mortality were: BMI (HR = 0.77, p = 0.011), AMF volume (HR = 1.04, p = 0.018), CPB (HR = 1.42, p = 0.002), ischaemic time (HR = 1.01, p = 0.009).Factors predicting survival were: AMF volume (HR = 1.02, p < 0.001), CPB (HR = 3.17, p = 0.003), ischaemic time (HR = 1.01, p = 0.001).ConclusionPreoperative radiological assessment of mediastinal fat dimensions and volumes may be a useful tool to identify fibrotic patients at higher risk of mortality after single lung transplantation.     

Characterization of Knee Osteoarthritis in Latin America. A Comparative Analysis of Clinical and Health Care Utilization in Argentina,Brazil, and Mexico

BackgroundThe burden of knee osteoarthritis (OA) in Latin America is unknown.ObjectiveTo determine the demographic, clinical, and therapeutic characteristics of patients with OA in Argentina, Brazil, and Mexico.Material and methodsThis is an observational, cross-sectional study of patients with symptomatic knee OA referred from first care medical centers to Rheumatology departments.ResultsWe included 1210 patients (Argentina 398, Brazil 402, Mexico 410; mean age 61.8 [12] years; 80.8% females). Knee OA pain lasted for 69 months; the duration and severity of the last episode were 190 days and (SD 5.2 [3.3]; 74% had functional limitations, but very few patients lost their job because of knee OA. Around 71% had taken medications, but 63% relied on their own pocket to afford knee OA cost. Most demographic and clinical variables differed across countries, particularly the level of pain, disability, treatment, and access to care. The variable country of origin influenced the level of pain, disability, and NSAIDs use in logistic regression models; age, pain, treatment, and health care access influenced at least 2 of the models.ConclusionsThe burden of knee OA in Latin American depends on demographic, clinical, and therapeutic variables. The role of such variables differs across countries. The level of certain variables is significantly influenced by country of origin and health care system.
