Measuring the Effect of Spell Recurrence on Poverty Dynamics

The analysis of poverty dynamics yields important insights about the expected effectiveness of alternative social policies on poverty reduction. This paper analyses the effect of spell recurrence on poverty dynamics taking into account multiple poverty and non-poverty spells. Using longitudinal data for Spain we obtain that the poverty exit and re-entry rates vary not only with personal or household characteristics but also with spell accumulation and with the duration of past spells. Results indicate that the effect of duration dependence is significant and turns out to be different by spell order. Our findings support progress towards incorporating full individual poverty trajectories more explicitly in estimating the likelihood of future poverty.poverty dynamics, multiple spells, recurrence

Antibodies against Chlamydia pneumoniae in stable angina and interleukin-6 levels

Producción CientíficaInflammation is a key mechanism in atherogenesis and the rapid progression of coronary artery disease. Tissue lesion occasions the release of chemical mediators, cytokines, accompanied by an increase in the blood concentrations of acute phase reactants, such as fibrinogen, C-reactive protein, serum amyloid A protein, sialic acid and ceruloplasmin and a reduction of those of albumin. It has been observed that these proteins are higher in patients with is-chemic heart disease and, furthermore, who have a higher tendency to present adverse cardiovascular incidents [1]. On the other hand, the inflammation appears to be directly linked to the ‘vulnerability’ or ‘instability’ of the atheromatous plaques that pre-dispose to disruption and acute coronary incidents. The inflammatory mechanism, therefore, can repre-sent the final common connection channel of chronic infection between atherogenesis and the clinical manifestations of coronary artery disease [2]

SEOM SOGUG clinical guideline for treatment of kidney cancer (2022)

Diagnosis; Guidelines; Renal cell carcinomaDiagnóstico; Guías; Carcinoma de células renalesDiagnòstic; Guies; Carcinoma de cèl·lules renalsRenal cancer is the seventh most common cancer in men and the tenth in women. The aim of this article is to review the diagnosis, treatment, and follow-up of renal carcinoma accompanied by recommendations with new evidence and treatment algorithms. A new pathologic classification of RCC by the World Health Organization (WHO) was published in 2022 and this classification would be considered a "bridge" to a future molecular classification. For patients with localized disease, surgery is the treatment of choice with nephron-sparing surgery recommended when feasible. Adjuvant treatment with pembrolizumab is an option for intermediate-or high-risk cases, as well as patients after complete resection of metastatic disease. More data are needed in the future, including positive overall survival data. Clinical prognostic classification, preferably IMDC, should be used for treatment decision making in mRCC. Cytoreductive nephrectomy should not be deemed mandatory in individuals with intermediate-poor IMDC/MSKCC risk who require systemic therapy. Metastasectomy can be contemplated in selected subjects with a limited number of metastases or long metachronous disease-free interval. For the population of patients with metastatic ccRCC as a whole, the combination of pembrolizumab-axitinib, nivolumab-cabozantinib, or pembrolizumab-lenvatinib can be considered as the first option based on the benefit obtained in OS versus sunitinib. In cases that have an intermediate IMDC and poor prognosis, the combination of ipilimumab and nivolumab has demonstrated superior OS compared to sunitinib. As for individuals with advanced RCC previously treated with one or two antiangiogenic tyrosine-kinase inhibitors, nivolumab and cabozantinib are the options of choice. When there is progression following initial immunotherapy-based treatment, we recommend treatment with an antiangiogenic tyrosine-kinase inhibitor. While no clear sequence can be advocated, medical oncologists and patients should be aware of the recent advances and new strategies that improve survival and quality of life in the setting of metastatic RC

Medidas de propiedades dieléctricas de materiales de construcción mediante elipsometría

A set of measurements of electromagnetic properties of building materials is presented in this work. The method is based on the measurement of the polarization state of the reflected signal from the material under study at a fixed angle of incidence. From the measured data, by using the Fresnel equations, it has been obtained the dielectric constant. Measurements were done by using two horn antennas at the frequency of 9 GHz. The obtained results are compared with the free space reflexion and transmission Fresnel method and other reflection methods based on a conductor waveguide. The method explained in this work can be used for other type of materials and its main advantage is the non-destructive character and the ease implementation

Interventions to improve adherence to first-line antibiotics in respiratory tract infections. The impact depends on the intensity of the intervention.

BACKGROUND: Many interventions aimed at improving the quality of antibiotic prescribing have been investigated, but more knowledge is needed regarding the impact of different intensity interventions. OBJECTIVES: To compare the effect of two interventions, a basic intervention (BI) and intensive intervention (II), aimed to improve the adherence to recommendations on first-line antibiotics in patients with respiratory tract infections (RTIs). METHODS: General practitioners (GPs) from different regions of Spain were offered two different interventions on antibiotic prescribing. They registered all patients with RTIs during 15 days before (2008) and after (2009) the intervention. GPs in Catalonia were exposed to BI including prescriber feedback, clinical guidelines and training sessions focused on appropriate antibiotic prescribing. The other group of GPs was exposed to an II, which besides BI, also included training and access to point-of-care tests in practice. RESULTS: The GPs registered 15 073 RTIs before the intervention and 12 760 RTIs after. The antibiotic prescribing rate reduced from 27.7% to 19.8%. Prescribing of first-choice antibiotics increased after the intervention in both groups. In the group of GPs following the BI, first-line antibiotics accounted for 23.8% of antibiotics before the intervention and 29.4% after (increase 5.6%, 95% confidence interval (CI): 1.2-10%), while in the group of GPs following the II these figures were 26.2% and 48.6% (increase 22.4%, 95% CI: 18.8-26%), respectively. CONCLUSION: Multifaceted interventions targeting GPs can improve adherence to recommendations for first-line antibiotic prescribing in patients with RTI, with intensive interventions that include point-of-care testing being more effective

Identification of the most vulnerable populations in the psychosocial sphere: a cross-sectional study conducted in Catalonia during the strict lockdown imposed against the COVID-19 pandemic.

Design and objectives A cross-sectional study to evaluate the impact of COVID-19 on the psychosocial sphere in both the general population and healthcare workers (HCWs). Methods The study was conducted in Catalonia (Spain) during the first wave of the COVID-19 pandemic when strict lockdown was in force. The study population included all people aged over 16 years who consented to participate in the study and completed the survey, in this case a 74-question questionnaire shared via social media using snowball sampling. A total of 56 656 completed survey questionnaires were obtained between 3 and 19 April 2020. The primary and secondary outcome measures included descriptive statistics for the non-psychological questions and the psychological impact of the pandemic, such as depression, anxiety, stress and post-traumatic stress disorder question scores. Results A n early and markedly negative impact on family finances, fear of working with COVID-19 patients and ethical issues related to COVID-19 care among HCWs was observed. A total of seven target groups at higher risk of impaired mental health and which may therefore benefit from an intervention were identified, namely women, subjects aged less than 42 years, people with a care burden, socioeconomically deprived groups, people with unskilled or unqualified jobs, patients with COVID-19 and HCWs working with patients with COVID-19. Conclusions Active implementation of specific strategies to increase resilience and to prepare an adequate organisational response should be encouraged for the seven groups identified as high risk and susceptible to benefit from an intervention

Urea cycle disorders in Argentine patients: Clinical presentation, biochemical and genetic findings

The incidence, prevalence, and molecular epidemiology of urea cycle disorders (UCDs) in Argentina remain underexplored. The present study is the first to thoroughly assess the clinical and molecular profiles of UCD patients examined at a single reference center in Argentina. Forty-nine UCD cases were collected. About half (26/49, 53%) manifested neonatally with classical presentation and had a high mortality (25/26, 96%). Ornithine transcarbamylase deficiency (OTCD) was the most common UCD (26 patients). Argininosuccinate synthetase deficiency (ASSD) was detected in 19 cases, while argininosuccinate lyase deficiency (ASLD) was diagnosed in 4 cases. Molecular genetic analysis revealed 8 private OTC mutations and two large deletion/duplication events in the OTC gene. Most mutations in the ASS1 and ASL genes were recurrent missense changes, and four alterations were novel. The clinical outcome of our UCD cohort was poor, with an overall mortality of 57% (28/49 cases), and a 28% (6/21) disability rate among the survivors. Most patients in our case series showed severe neonatal onset, with high morbidity/ mortality. We detected in total 19 mutations, most of them recurrent and of high frequency worldwide. Noteworthy, we highlight the presence of a geographic cluster with high prevalence of a point mutation in the ASS1 gene. This study suggests that these disorders may be more frequent than commonly assumed, and stresses the need for increased awareness amongst health professionals and greater availability of diagnostic tools for accurate identification, earlydiagnosis, and timely treatment.Fil: Silvera Ruiz, Silene Maite.

Anti-CXCR4 Antibody Combined With Activated and Expanded Natural Killer Cells for Sarcoma Immunotherapy

Sarcoma is one of the most severe forms of pediatric cancer and current therapies -chemotherapy and surgery- fail to eradicate the disease in half of patients. Preclinical studies combining new therapeutic approaches can be useful to design better therapies. On one hand, it is known that CXCR4 expression is implicated in rhabdomyosarcoma progression, so we analyzed relapses and chemotherapy-resistant rhabdomyosarcoma tumors from pediatric patients and found that they had particularly high levels of CXCR4 expression. Moreover, in assays in vitro, anti-CXCR4 blocking antibody (MDX1338) efficiently reduced migration and invasion of alveolar rhabdomyosarcoma RH30 cells. On the other hand, activated and expanded natural killer (NKAE) cell therapy showed high cytotoxicity against sarcoma cells in vitro and completely inhibited RH30 tumor implantation in vivo. Only the combination of MDX1338 and NKAE treatments completely suppressed metastasis in mice. In this study, we propose a novel therapeutic approach based on anti-CXCR4 blocking antibody in combination with NKAE cell therapy to prevent rhabdomyosarcoma tumor implantation and lung metastasis. These results provide the first evidence for the efficacy of this combined immunotherapy for preventing sarcoma disease dissemination.This work was supported in part by the National Health Service of Spain, Instituto de Salud Carlos III (ISCIII), FONDOS FEDER grant (FIS) PI15/00973; Asociacion Espanola Contra el Cancer to AP-M; CRIS Foundation to Beat Cancer grant to JV, LF, and AE; and Patients' Support Associations Fundacion Mari Paz Jimenez Casado and La Sonrisa de Alex to MV and the research project
