Urban areas, human health and technosols for the green deal.

Authors aim to carry out a bibliographic review as an initial approach to state of the art related to the quality of urban soils, as well as its possible link with human health. This concern arises from the need to highlight the consequences that soil could face, derived from the growth and aging of the population, as well as its predicted preference for urban settlement. Urban development may pose a challenge to the health of urban soils, due to degradative processes that it entails, such as land take, sealing, contamination or compaction. A healthy soil is the one which maintains the capacity to support ecosystem services, so it can provide numerous benefits to human health and well-being (carbon sequestration, protection against flooding, retention and immobilization of pollutants and a growth media for vegetation and food production). This article addresses threats facing urban soils, the strategies put forward by the European Union to deal with them, as well as the issues that require further attention. Greening cities could be a consensual solution, so authors analyze whether soils of cities are ready for that challenge and what resources need to maintain soil ecosystem functions. This review proposes to use made by waste Technosols for a sustainable green city. Although the use of Technosols as a type of soil is very recent, the interest of the scientific community in this field continues to grow.

A propensity-score-matched analysis of laparoscopic vs open surgery for rectal cancer in a population-based study.

AIM: The oncological risk/benefit trade-off for laparoscopy in rectal cancer is controversial. Our aim was to compare laparoscopic vs open surgery for resection of rectal cancer, using unselected data from the public healthcare system of Catalonia (Spain). METHODS: This was a multicentre retrospective cohort study of all patients who had surgery with curative intent for primary rectal cancer at Catalonian public hospitals from 2011 to 2012. We obtained follow-up data for up to 5 years. To minimize the differences between the two groups, we performed propensity score matching on baseline patient characteristics. We used multivariate Cox proportional hazards regression analyses to assess locoregional relapse at 2 years and death at 2 and 5 years. RESULTS: Of 1513 patients with Stage I-III rectal cancer, 933 (61.7%) had laparoscopy (conversion rate 13.2%). After applying our propensity score matching strategy (2:1), 842 laparoscopy patients were matched to 517 open surgery patients. Multivariate Cox analysis of death at 2 years [hazard ratio (HR) 0.65, 95% CI 0.48, 0.87; P = 0.004] and 5 years (HR 0.61, 95% CI 0.5, 0.75; P < 0.001) and of local relapse at 2 years (HR 0.44, 95% CI 0.27, 0.72; P = 0.001) showed laparoscopy to be an independent protective factor compared with open surgery. CONCLUSIONS: Laparoscopy results in lower locoregional relapse and long-term mortality in rectal cancer in unselected patients with all-risk groups included. Studies using long-term follow-up of cohorts and unselected data can provide information on clinically relevant outcomes to supplement randomized controlled trials.

Expert consensus on the persistence of biological treatments in moderate-to-severe psoriasis.

BACKGROUND: Treatment persistence is becoming a useful measure to evaluate long-term effectiveness and safety of biological therapies in real-world settings. OBJECTIVE: The main objective of this study was to explore the scientific opinion of a panel of dermatologists and hospital pharmacists to reach a consensus about the impact, causes, and best strategies and interventions that might be associated with improved drug persistence in patients with psoriasis in Spain. METHODS: This research was conducted using a modified Delphi method organized in two rounds and involving a panel of 90 dermatologists and 34 hospital pharmacists. A questionnaire of 70 items was developed. The items proposed to reach a consensus included topics such as definitions and measures in the treatment of psoriasis, analysis of treatment persistence, factors that may influence treatment persistence, impact of treatment persistence and economic cost of treatment. RESULTS: Dermatologists reached a consensus on 77.1% of the items proposed, and hospital pharmacists reached a consensus on 71.4%. Both groups agreed that it is important to use standardized measures in the evaluation of treatment maintenance over time. Dermatologists agreed that treatment survival, persistence and retention are synonymous, but hospital pharmacists considered only treatment persistence as a valid term. In addition, panelists agreed that drug persistence is an indicator of success in the treatment of psoriasis that may be influenced by a drug's effectiveness and safety profile, as well as by patient satisfaction. They agreed that the different causes of treatment discontinuation should be considered in Kaplan-Meier analysis of treatment persistence. Moreover, treatment persistence was agreed to decrease the cost of therapy. CONCLUSION: This Delphi consensus highlights the different perspectives of dermatologists and hospital pharmacists regarding the interpretation of treatment persistence, and the challenge of harmonizing the results obtained.

Differences in Treatment and Outcome of Pancreatic Adenocarcinoma Stage I and II in the EURECCA Pancreas Consortium.

BACKGROUND: The EUropean REgistration of Cancer CAre (EURECCA) consortium aims to investigate differences in treatment and to improve cancer care through Europe. The purpose of this study was to compare neo- and adjuvant chemotherapy (ACT) and outcome after tumor resection for pancreatic adenocarcinoma stage I and II in the EURECCA Pancreas consortium. METHODS: The eight, collaborating national, regional, and single-center partners shared their anonymized dataset. Patients diagnosed in 2012-2013 who underwent tumor resection for pancreatic adenocarcinoma stage I and II were investigated with respect to treatment and survival and compared using uni- and multivariable logistic and Cox regression analyses. All comparisons were performed separately per registry type: national, regional, and single-center registries. RESULTS: In total, 2052 patients were included. Stage II was present in the majority of patients. The use of neo-ACT was limited in most registries (range 2.8-15.5%) and was only different between Belgium and The Netherlands after adjustment for potential confounders. The use of ACT was different between the registries (range 40.5-70.0%), even after adjustment for potential confounders. Ninety-day mortality was also different between the registries (range 0.9-13.6%). In multivariable analyses for overall survival, differences were observed between the national and regional registries. Furthermore, patients in ascending age groups and patients with stage II showed a significant worse overall survival. CONCLUSIONS: This study provides a clear insight in clinical practice in the EURECCA Pancreas consortium. The differences observed in (neo-)ACT and outcome give us the chance to further investigate the best practices and improve outcome of pancreatic adenocarcinoma.

The role of posttraumatic stress and posttraumatic growth on online information use in breast cancer survivors.

OBJECTIVE: Changes perceived as both positive (eg, posttraumatic growth [PTG]) and negative (eg, posttraumatic stress symptoms [PTSS]) have been associated with intensive Internet use among breast cancer survivors. In this multicenter study, we analyzed the role of PTG and PTSS on the amount of time spent looking for online cancer information, its content, and its psychological impact. METHODS: Posttraumatic stress symptoms and PTG were assessed in 182 breast cancer survivors by using the Post-traumatic Stress Disorder Checklist and Post-traumatic Growth Inventory questionnaires. Subjects also completed a questionnaire about their behavior when looking for online illness-related information (ie, time spent, type of contents, and psychological impact). RESULTS: Posttraumatic stress symptoms positively correlated with the amount of time spent looking for cancer-related information, including both medical and psychosocial content. By contrast, PTG showed no relationships with the amount of time, but with a predominant search for cancer-related psychosocial information. The psychological impact of online information was associated with participants' levels of PTG and/or PTSS. Whereas PTG was related to a decrease of women's hope, PTSS was linked to the perception of being less conscious or inadequately informed about the illness, thereby increasing feelings of distress. CONCLUSIONS: Posttraumatic stress symptoms and PTG show relationships with the amount of time spent online, the type of information accessed online, and the psychological impact of Internet use. Health professionals should prescribe online information according to the psychological response to cancer. There is a need for professional-led online resources to provide patients with timely information as well as support sites to facilitate psychological adjustment.

Substance use disorders in patients with intellectual disability admitted to psychiatric hospitalisation.

BACKGROUND: Few studies have looked at the prevalence of substance use disorders (SUD) in people with intellectual disability (ID). The results range between 1% and 6.4% and go up to 20% in people with ID and psychiatric disorders, probably underestimating real prevalence due to several limitations in these studies. ID confers risk for the development of SUD, which in turn will involve negative psychosocial and clinical consequences. We aimed to study the prevalence of SUD in a sample of patients with ID admitted to a brief hospitalisation psychiatric unit, describing them by type and severity and analysing their relationship with clinical, prognostic and access to treatment variables. METHODS: We undertook a descriptive, cross-sectional and retrospective study by means of a review of clinical histories of all patients with a diagnosis of ID, admitted in a period of 10 years. RESULTS: Among the final sample of patients included, 52.3% had a mild ID, 40.9% an unspecified ID, 3.4% a moderate ID and another 3.4% a severe ID. More than one third of the sample met criteria for a SUD. The main SUD was cannabis use disorder (25%), followed by alcohol use disorder (22.7%) and cocaine use disorder (13.6%). The use of more than one substance was the most frequent pattern. Cannabis use disorder and cocaine use disorder were overrepresented in the group with mild ID. A greater number of psychiatric admissions was observed for the group with SUD. Specialised mental health services for ID and specialised addiction network facilities were much less involved in the care of these patients that could be expected according to good clinical practice recommendations. CONCLUSIONS: Substance use disorder in patients with ID and mental health disorders admitted to psychiatric hospitalisation are prevalent, which makes this issue an area of interest for future improvements in case identification, proper referring to specialised treatment resources and an increasing research focusing on specific therapeutic approaches.

Adherence to capecitabine in preoperative treatment of stage II and III rectal cancer: do we need to worry?

BACKGROUND: Preoperative oral capecitabine plus radiotherapy has been progressively adopted in oncology units to provide more convenient care to patients with rectal cancer, but little is known about adherence to this therapy. PATIENTS AND METHODS: Prospective, multicentre observational study in six hospitals in metropolitan Barcelona (Spain), in patients with stage II and III rectal cancer. Assessment of adherence was based on the medical report in the clinical history, a patient questionnaire and a pill count in the pharmacy service upon finalization of treatment. Patients were considered adherent if they had taken 80%-110% of the prescribed treatment. We evaluated clinical variables, adverse effects, anxiety and depression (using the hospital anxiety depression scale [HADS]), and quality of life (EORTC QLQ-30). We analysed adherence-associated variables using a logistic regression model and concordance between adherence measures by means of the modified Kappa index. RESULTS: We included 119 participants. Adherence measures showed little concordance between the assessment methods used: adherence was 100% according to the clinical history, 83.2% according to self-report and 67.9% according to the pill count. In the multivariable analysis, the most relevant variable associated with non-adherence was anxiety prior to treatment (adjusted odds ratio [ORa] 6.96, 95% confidence interval [CI] 1.48-32.7). We did not observe any relevant association between adherence and clinical variables and baseline quality of life parameters. CONCLUSIONS: Adherence to short-term oral neoadjuvant treatment in rectal cancer may be a clinical problem, and it should be acknowledged and systematically evaluated by clinicians during treatment. The limited concordance between different measures of adherence highlights the challenges in monitoring it and the need to use different approaches to assess its impact in clinical practice.

Prescription refill, patient self-report and physician report in assessing adherence to oral endocrine therapy in early breast cancer patients: a retrospective cohort study in Catalonia, Spain.

AIMS: To compare different methods in order to assess adherence and persistence with oral endocrine therapy in women diagnosed with breast cancer (BC) in Catalonia. MATERIALS AND METHODS: This study covered all women newly diagnosed with stage I, II or IIIa BC and positive hormone receptors at six hospitals in Catalonia (Spain) in 2004. Adherence was assessed on the basis of physician report and patient self-report using a telephone questionnaire. Persistence was measured by refill prescriptions. We used the Kappa index to compare adherence measures and logistic regression to evaluate adherence-related risk factors. RESULTS: The study covered a total of 692 women. Adherence ranged from 92% (self-report) to 94.7% (physician report), depending on the measure used; persistence was 74.7% at 5 years of follow-up. Low concordance between measures was observed (Kappa range: 0.018-0.267). Patients aged 50-74 years showed higher adherence than those aged <50 years. Adherence was also associated with: adjuvant chemotherapy and sequential hormonal therapy. CONCLUSIONS: Concordance between the different measures was remarkably low, indicating the need for further research. Adherence is an issue in the management of BC patients taking oral drugs, and should be assessed in clinical practice.

Cancer diagnosis in Catalonia (Spain) after two years of COVID-19 pandemic: an incomplete recovery.

BACKGROUND: This study aimed to estimate potential undetected cancers over the first 2 years of the COVID-19 pandemic in Catalonia. METHODS: Cancer incidence was compared between pre-pandemic (2019) and pandemic (March 2020-January 2022) periods in the Catalan Pathology Registry (CPR) according to sex, age, and tumor site. The correlation between cancer diagnosis and COVID-19 health care workload was also evaluated by means of the Pearson's correlation coefficient (R). The expected incident cancers (E) during the pandemic were estimated by applying 2019 CPR cancer incidence specific rates by sex and 5-year age groups to the 2020 and 2021 Catalan population pyramids. CPR incident cancers were considered observed (O). Standardized incidence ratios (SIR) and 95% confidence intervals (CIs) were calculated using the O/E ratio. RESULTS: After two pandemic years, cancer diagnosis decreased by 12% (SIR 0.88, 95% CI 0.87-0.89), or ∼7700 undetected cancers (13 000 with nonmelanoma skin cancer). Without nonmelanoma skin cancer, 72% of the cancer underdiagnosis was generated in 2020. Diagnoses decreased more in men (whole pandemic -14%; 2020 -21%; 2021 -8%) than in women (-9%, -19%, -3%, respectively), dropping significantly overall in all pandemic waves but the fifth (first -37%, second -16%, third -8%, fourth -6%, fifth -2%, sixth -6%), and across all adult age groups. In the first wave, CPR cancer diagnosis was inversely correlated with COVID-19 caseload in primary care (R -0.91, 95% CI -0.97 to -0.75) and occupancy in conventional hospital wards (R -0.91, 95% CI -0.99 to -0.48) and intensive care (R -0.91, 95% CI 95% -0.98 to -0.70). CONCLUSIONS: Our study evaluated the overall pandemic impact on cancer diagnosis on a large scale and with minimal selection bias, showing that as of February 2022, cancer detection in Catalonia had not yet recovered to pre-pandemic levels. Pending cancer incidence data from population-based cancer registries, early CPR data could inform the development of Spanish cancer control plans.

Response to azacitidine in patients with chronic myelomonocytic leukemia according to overlap myelodysplastic/myeloproliferative neoplasms criteria.

BACKGROUND: Azacitidine (AZA) is approved for the treatment of high-risk chronic myelomonocytic leukemia (CMML) of myelodysplastic (MD) subtype. Data of response rates using the specific response criteria for this disease are scarce. The aim of this study was to evaluate the response to AZA in patients diagnosed with CMML from the Spanish Registry of Myelodysplastic Syndromes (MDS) applying the overlap myelodysplastic/myeloproliferative neoplasms (MDS/MPN) response criteria. METHODS: We retrospectively studied 91 patients with CMML treated with at least one cycle of AZA from the Spanish Registry of MDS. As it was a real-world study, the response rate was evaluated between cycle 4 and 6, applying the MDS/MPN response criteria FINDINGS: The overall response rate at cycle 4-6 was 58%. Almost half of the patients achieved transfusion independence and one quarter showed clinical benefit, regardless of the CMML French-American-British (FAB) and World Health Organization (WHO) subtypes and CMML Specific Prognosis Scoring (CPSS) risk groups. Toxicity was higher in the MD-CMML subtype. INTERPRETATION: In our series, most CMML patients achieved an overall response rate with AZA according to the overlap-MDS/MPN response criteria regardless of the CMML FAB and WHO subtypes and CPSS risk groups. Thus, AZA may also be a treatment option for patients with the myeloproliferative CMML subtype and those with a lower-risk CPSS, but symptomatic.

Implementing a Cancer Fast-track Programme between primary and specialised care in Catalonia (Spain): a mixed methods study.

BACKGROUND: The Cancer Fast-track Programme's aim was to reduce the time that elapsed between well-founded suspicion of breast, colorectal and lung cancer and the start of initial treatment in Catalonia (Spain). We sought to analyse its implementation and overall effectiveness. METHODS: A quantitative analysis of the programme was performed using data generated by the hospitals on the basis of seven fast-track monitoring indicators for the period 2006-2009. In addition, we conducted a qualitative study, based on 83 semistructured interviews with primary and specialised health professionals and health administrators, to obtain their perception of the programme's implementation. RESULTS: About half of all new patients with breast, lung or colorectal cancer were diagnosed via the fast track, though the cancer detection rate declined across the period. Mean time from detection of suspected cancer in primary care to start of initial treatment was 32 days for breast, 30 for colorectal and 37 for lung cancer (2009). Professionals associated with the implementation of the programme showed that general practitioners faced with suspicion of cancer had changed their conduct with the aim of preventing lags. Furthermore, hospitals were found to have pursued three specific implementation strategies (top-down, consensus-based and participatory), which made for the cohesion and sustainability of the circuits. CONCLUSION: The programme has contributed to speeding up diagnostic assessment and treatment of patients with suspicion of cancer, and to clarifying the patient pathway between primary and specialised care.

Germline ATM mutational analysis in BRCA1/BRCA2 negative hereditary breast cancer families by MALDI-TOF mass spectrometry.

Biallelic inactivation of ATM gene causes the rare autosomal recessive disorder Ataxia-telangiectasia (A-T). Female relatives of A-T patients have a two-fold higher risk of developing breast cancer (BC) compared with the general population. ATM mutation carrier identification is laborious and expensive, therefore, a more rapid and directed strategy for ATM mutation profiling is needed. We designed a case-control study to determine the prevalence of 32 known ATM mutations causing A-T in Spanish population in 323 BRCA1/BRCA2 negative hereditary breast cancer (HBC) cases and 625 matched Spanish controls. For the detection of the 32 ATM mutations we used the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry technique. We identified one patient carrier of the c.8264_8268delATAAG ATM mutation. This mutation was not found in the 625 controls. These results suggest a low frequency of these 32 A-T causing mutations in the HBC cases in our population. Further case-control studies analyzing the entire coding and flanking sequences of the ATM gene are warranted in Spanish BC patients to know its implication in BC predisposition.

Factors associated with initial participation in a population-based screening for colorectal cancer in Catalonia, Spain: a mixed-methods study.

OBJECTIVE: To identify barriers and facilitators associated with participation in the first round of a population-based program for colorectal cancer (CRC) in Catalonia, Spain and to identify strategies for motivating and supporting behavioral change. MATERIAL AND METHODS: A two-part, mixed-methods design was used. In first place, a prospective study of individuals aged 50-69 years (n=1961) was conducted in 2006-2007. Secondly, focus groups were undertaken with participants and non-participants of the CRC screening, in 2008. RESULTS: Intention to participate was an important determinant of participation (82.9% vs 65.9%, OR=2.56, 95%CI:1.95-3.36) in addition to knowledge about CRC and its early detection. Respondents who reported that CRC may be asymptomatic in early stages enrolled in the screening program more frequently than those who thought CRC is always symptomatic (49.4% vs 44.8%, OR:1.82; 95%CI:1.3-2.6). Barriers for participation mentioned in focus groups were competing perceived for other health problems and other demands as well as misunderstanding about personal relevance of the screening. CONCLUSION: Individuals' perceptions of CRC are amenable to change through education-based interventions. Increasing public knowledge related to the burden of CRC and its preventive potential may be an effective way for improving participation in a population-based screening program.

Female and male fitness of a sexually deceptive orchid with a narrow distribution area: from phenotypic traits to spatial distribution patterns.

The Orchidaceae family presents one of the most extravagant pollination mechanisms: deception. While many studies on reproductive success have been performed on food-deception orchids, less have been performed on sexually deceptive orchids. Here, we focused on Ophrys balearica P. Delforge, an endemic orchid of the Balearic Islands, to study its reproductive ecology, the spatio-temporal variation of its reproductive success and the individual (floral display and geospatial position) and population parameters (patch size, shape and density) that affect its reproductive success. We performed hand-pollination experiments, along with the recording of floral display parameters and GPS position of over 1,100 individuals from seven populations in two consecutive years. We applied, for the first time, GIS tools to analyse the effects of individual's position within the population on the reproductive success. Reproductive success was measured both in male (removed pollinia) and female (fruit set) fitness. The results confirm that this species is pollinator-dependent and mostly allogamous, but also self-compatible. This species showed high values for the cumulative inbreeding depression index and high pollen limitation. Male fitness was almost equal to female fitness between years and populations, and reproductive success exhibited huge spatio-temporal variation. Although we did not find strong correlations between floral display and reproductive success, patches with low-plant density and individuals in the external portion of the population showed significantly higher plant fitness. These findings must be considered in conservation actions for endangered orchid species, especially considering that most orchids are strongly dependent on pollinators for their species' fitness.

Ecological factors affecting the fitness of the threatened orchid Anacamptis robusta (Orchidaceae): Habitat disturbance, interactions with a co-flowering rewarding orchid and hybridization events.

The food-deceptive species Anacamptis robusta is threatened in the Balearic Islands, and its habitat has recently been transformed through human disturbance. This study investigated how human disturbance affects the reproductive output of A. robusta and how its fitness is affected by competition with rewarding relatives, fungal infections and hybridization processes. To evaluate the impact of habitat loss on plant fitness, data on reproductive measures were obtained in two well-conserved subpopulations and the unique disturbed subpopulation. Photo-trapping cameras were installed to determine the floral visitation rate. All flowering individuals in 2019 were georeferenced using differential GPS to examine the influence of geospatial patterns on the reproductive success of A. robusta. In addition, hand-pollination treatments were performed to evaluate the hybridization between A. coriophora and A. robusta and the origin of A. × albuferensis. The human-disturbed subpopulation of A. robusta had a lower fruit set success than the subpopulations in well-conserved areas. The presence of A. coriophora is negatively affecting the reproductive output of A. robusta. Moreover, A. robusta can only act as the pollen donor during hybridization. The complexity of the ecological system, which is enhanced by the strong pollinator dependence of the threatened species, must be considered when making conservation decisions. Although human disturbance directly affects plant population stability, other ecological issues must be considered, such as pollinator interaction, interspecific competition for pollinators, fungal infection and hybridization events.

Population-based risk assessment of second primary cancers following a first head and neck cancer: patterns of association and difficulties of its analysis.

PURPOSE: The diagnosis of a second primary cancer (SPC) is a major concern in the follow-up of survivors of a primary head and neck cancer (HNC), but the anatomic subsites in the head and neck area are close, making it difficult to distinguish a SPC of a recurrence and therefore register it correctly. METHODS: We performed a retrospective cohort study using data from two population-based cancer registries in Catalonia, Spain: the Tarragona Cancer Registry and the Girona Cancer Registry. All patients diagnosed with HNC during the period 1994-2013 were registered and followed-up to collect cases of SPC. We analysed the standardized incidence ratio (SIR) and the excess absolute risk (EAR) to determine the risk of second malignancies following a prior HNC. RESULTS: 923 SPC were found in a cohort of 5646 patients diagnosed of a first head and neck cancer. Men had an increased risk of a SPC with a SIR of 2.22 and an EAR of 216.76. Women also had an increased risk with a SIR of 2.02 and an EAR of 95.70. We show the risk for different tumour sites and discuss the difficulties of the analysis. CONCLUSION: The risks of a SPC following a prior HNC in Tarragona and Girona are similar to those previously found in other similar cohorts. It would appear to be advisable to make a revision of the international rules of classification of multiple tumours, grouping the sites of head and neck area with new aetiological criteria to better determine and interpret the risks of SPC obtained in these studies.

Different methylation signatures at diagnosis in patients with high-risk myelodysplastic syndromes and secondary acute myeloid leukemia predict azacitidine response and longer survival.

BACKGROUND: Epigenetic therapy, using hypomethylating agents (HMA), is known to be effective in the treatment of high-risk myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients who are not suitable for intensive chemotherapy and/or allogeneic stem cell transplantation. However, response rates to HMA are low and there is an unmet need in finding prognostic and predictive biomarkers of treatment response and overall survival. We performed global methylation analysis of 75 patients with high-risk MDS and secondary AML who were included in CETLAM SMD-09 protocol, in which patients received HMA or intensive treatment according to age, comorbidities and cytogenetic. RESULTS: Unsupervised analysis of global methylation pattern at diagnosis did not allow patients to be differentiated according to the cytological subtype, cytogenetic groups, treatment response or patient outcome. However, after a supervised analysis we found a methylation signature defined by 200 probes, which allowed differentiating between patients responding and non-responding to azacitidine (AZA) treatment and a different methylation pattern also defined by 200 probes that allowed to differentiate patients according to their survival. On studying follow-up samples, we confirmed that AZA decreases global DNA methylation, but in our cohort the degree of methylation decrease did not correlate with the type of response. The methylation signature detected at diagnosis was not useful in treated samples to distinguish patients who were going to relapse or progress. CONCLUSIONS: Our findings suggest that in a subset of specific CpGs, altered DNA methylation patterns at diagnosis may be useful as a biomarker for predicting AZA response and survival.
