ABSTRACT

Transformative capacity (TC) is key for addressing climate change impacts. It refers to urban areas' ability for profound and intentional change to address current challenges and move towards a more desirable and resilient state. However, its varied applications across disciplines can lead to misunderstandings and implementation challenges. Thus, this Semi-Systematic Literature Review (SSLR) on TC within urban studies from 2016 to 2022 aims to overview and synthesise TC literature and its gaps to inform ongoing debates, intersecting it with climate-related research. The results show an increasing interest in TC within two fields of knowledge: resilience studies and transformative research. The review found TC as a catalyst for transformative actions, promoting sustainable pathways, enhancing resilience, and driving fundamental changes in urban climate adaptation. Finally, the prevailing literature gaps concern the TC concept's fragmentation, excessive research on governance features, and lack of joint research about TC and innovation.

ABSTRACT

OBJECTIVES: Our aim was to describe the epidemiological characteristics of COVID-19 cases in prison inmates in Spain and the control measures implemented to response to this public health challenge. STUDY DESIGN: Retrospective observational study. METHODS: All COVID-19-confirmed cases reported to the Spanish information system in prisons between March 2020 and June 2022 were analyzed. Prevention plans and protocols established by penitentiary and health authorities were reviewed. Likewise, information on vaccines administered to prison inmates was described. RESULTS: A total of 8500 COVID-19 cases were reported to penitentiary public health surveillance. The overall cumulative incidence (CI) was 2054.18 cases per 10,000 inmate population. By epidemic periods, the average weekly CI was 1.15 per 10,000 inmate population during the first period, 6.91 during the second, 25.18 during the third, 3.53 during the fourth, 23.27 during the fifth, 34.72 during the sixth and 25.68 during the seventh period. The median age of cases was 49.2 years, 69.1% was born in Spain, 64.1% was asymptomatic and 16 cases died. Ninety-four percent were vaccinated. Control measures such as lockdown, suspending visitation rights and confining inmates in their cells were adopted at the beginning of the pandemic. These measures changed in accordance with the COVID-19 situation in the general population with a view to restoring the inmates' rights. CONCLUSION: The COVID-19 pandemic has had a moderate incidence in Spanish prisons. Hospitalization and CFR were lower than the general population. The control measures adopted against COVID-19 have contributed to preventing and controlling the number of cases in prisons.

ABSTRACT

The presence of sinonasal ectopic teeth is a rare entity that is usually asymptomatic. In some cases, the presence of foreign bodies in the maxillary sinus, such as ectopic teeth, can lead to chronic maxillary sinusitis. We report a case of chronic sinusitis because of an ectopic tooth in the roof of the left maxillary sinus in a 50-year-old female who presented with complaints of facial pain in the left maxillary region and purulent nasal discharge. The treatment of ectopic teeth usually consists of the removal of the previous, taking into account its location and possible risks. In this case, the close proximity to the orbit could have led to a greater risk of complications involving the infraorbital bundle. CT scan evaluation is frequently required to identify the exact location and is useful for treatment planning. The traditional surgical approaches to maxillary sinus pathology are transoral Caldwell-Luc approaches or transnasal endoscopic surgery. The method used in this case was the Caldwell-Luc approach. Although more invasive, it allows visualization into the maxillary sinus and superior access for instrumentation of the posterolateral region while permitting manipulation and removal of larger objects. Despite maxillary sinus ectopic teeth being uncommon, it is important for clinicians to become aware and to consider this entity to provide early adequate treatment.

ABSTRACT

El objetivo del estudio fue caracterizar el potencial investigador cubano en el ámbito de las ataxias y su evolución temporal. Se realizó una búsqueda en la base de datos Web of Science y se obtuvieron todos los documentos publicados entre 1993 y 2020. Se aplicaron indicadores bibliométricos para explorar la producción, dispersión, distribución y crecimiento anual de los documentos (ley de Price, ley de Lotka, índice de transitoriedad y modelo de Bradford). Se calculó el índice de participación y colaboración de países e instituciones y, por cartografía bibliométrica, se exploraron las redes de coocurrencia de los términos más utilizados. La producción científica de Cuba sobre ataxias hereditarias es alta (219 documentos) y se ajusta a un crecimiento lineal (r= 0,7580). El período estudiado concentra el 47,95 por ciento de los registros con un ritmo anual de publicaciones del 6,6 por ciento y tiempo de duplicidad de 10,8 años. El total de citas fue de 3807 (índice medio: 131,27; índice -h: 31). Se concluye que el crecimiento de la literatura científica cubana sobre ataxias fue lineal para el período estudiado, lo que confirma el incumplimiento de la ley de Price de crecimiento de la literatura científica. El estudio también corrobora la importante red de integración y cooperación internacional entre los diferentes autores y la interdisciplinariedad de los trabajos, evidencia del éxito del Centro para la Investigación y Rehabilitación de las Ataxias Hereditarias (CIRAH), al planificar una estrategia de colaboración científica con objetivos definidos(AU)


The objective of this study was to characterize the Cuban research potential in the field of ataxias and its temporal evolution. A search was carried out in the Web of Science database and all the documents published from 1993 to 2020 were retrieved. Bibliometric indicators were applied to explore the production, dispersion, distribution and annual growth of the documents (Price's law, Lotka's law, transience index and Bradford model). The participation and collaboration index of countries and institutions was calculated and, through bibliometric cartography, the co-occurrence networks of the most used terms were explored. The Cuban scientific production on hereditary ataxias is high (219 documents) and it adjusts to a linear growth (r = 0.7580). The period studied concentrates 47.95percent of the records with an annual publication rate of 6.6percent and 10.8 years' duplication time. The total number of citations was 3807 (mean index: 131.27; h-index: 31). Growth of the Cuban scientific literature on ataxias was concluded to be linear for the period studied, which confirms the non-compliance with Price's law of growth of scientific literature. The study also corroborates the important network of integration and international cooperation among the different authors and the interdisciplinarity of the papers, marking the success of the Center for Research and Rehabilitation of Hereditary Ataxias (CIRAH), when planning a strategy of scientific collaboration with objectives defined(AU)

ABSTRACT

OBJECTIVE: The addition of maintenance olaparib to bevacizumab demonstrated a significant progression-free survival (PFS) benefit in patients with newly diagnosed, advanced ovarian cancer in the PAOLA-1/ENGOT-ov25 trial (NCT02477644). We evaluated maintenance olaparib plus bevacizumab in the Japan subset of PAOLA-1. METHODS: PAOLA-1 was a randomized, double-blind, phase III trial. Patients received maintenance olaparib tablets 300 mg twice daily or placebo twice daily for up to 24 months, plus bevacizumab 15 mg/kg every 3 weeks for up to 15 months in total. This prespecified subgroup analysis evaluated investigator-assessed PFS (primary endpoint). RESULTS: Of 24 randomized Japanese patients, 15 were assigned to olaparib and 9 to placebo. After a median follow-up for PFS of 27.7 months for olaparib plus bevacizumab and 24.0 months for placebo plus bevacizumab, median PFS was 27.4 versus 19.4 months, respectively (hazard ratio [HR]=0.34; 95% confidence interval [CI]=0.11-1.00). In patients with tumors positive for homologous recombination deficiency, the HR for PFS was 0.57 (95% CI=0.16-2.09). Adverse events in the Japan subset were generally consistent with those of the PAOLA-1 overall population and with the established safety and tolerability profiles of olaparib and bevacizumab. CONCLUSION: Results in the Japan subset of PAOLA-1 support the overall conclusion of the PAOLA-1 trial demonstrating that the addition of maintenance olaparib to bevacizumab provides a PFS benefit in patients with newly diagnosed, advanced ovarian cancer. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02477644.

ABSTRACT

BACKGROUND: The 'funnel effect' of Fibromyalgia (FM) assumes that as patients access healthcare services, they present greater severity and a more complex clinical situation than individuals with FM from the general population, but the studies comparing patients treated in different levels of healthcare are scarce. The aim of this study was to analyse the 'funnel effect' hypothesis by comparing patients from secondary and tertiary healthcare services. METHODS: A cross-sectional sample of female patients was selected in secondary (rheumatology practices - RP) and in tertiary healthcare (chronic pain clinics - CPC). Information about sociodemographic, clinical and psychological characteristics was collected and health related quality of life (HRQL) was assessed. RESULTS: In total, 55 patients from RP and 60 patients from CPC were included in the comparison. Patients from CPC revealed a worst clinical status (higher number of tender points, medical visits and comorbidity), more somatic symptoms (pain and daytime dysfunction levels) and worst emotional status (more anxiety) than patients from RP. Patients attending CPC also revealed a worst HRQL than RP patients although this difference was mediated by the differences in clinical and psychological variables. CONCLUSIONS: Our study supports the 'funnel effect' hypothesis among patients of different healthcare levels, with patients from tertiary healthcare services revealing worst clinical status, more somatic and psychological symptoms, and worst HRQL than patients from secondary healthcare services. SIGNIFICANCE: The worst clinical and psychological status and poorer quality of life in the patients from tertiary healthcare (chronic pain clinics) in relation to the patients from secondary healthcare (rheumatology practices) must be taken into account to design studies that assess any of these aspects, to a proper analysis and interpretation of the data, and to define the scope of its generalization, as data from different clinical settings are not directly comparable.

ABSTRACT

INTRODUCTION: Our study sought to know the current implementation of video-assisted thoracoscopic surgery (VATS) for anatomical lung resections in Spain. We present our initial results and describe the auditing systems developed by the Spanish VATS Group (GEVATS). METHODS: We conducted a prospective multicentre cohort study that included patients receiving anatomical lung resections between 12/20/2016 and 03/20/2018. The main quality controls consisted of determining the recruitment rate of each centre and the accuracy of the perioperative data collected based on six key variables. The implications of a low recruitment rate were analysed for "90-day mortality" and "Grade IIIb-V complications". RESULTS: The series was composed of 3533 cases (1917 VATS; 54.3%) across 33 departments. The centres' median recruitment rate was 99% (25-75th:76-100%), with an overall recruitment rate of 83% and a data accuracy of 98%. We were unable to demonstrate a significant association between the recruitment rate and the risk of morbidity/mortality, but a trend was found in the unadjusted analysis for those centres with recruitment rates lower than 80% (centres with 95-100% rates as reference): grade IIIb-V OR = 0.61 (p = 0.081), 90-day mortality OR = 0.46 (p = 0.051). CONCLUSIONS: More than half of the anatomical lung resections in Spain are performed via VATS. According to our results, the centre's recruitment rate and its potential implications due to selection bias, should deserve further attention by the main voluntary multicentre studies of our speciality. The high representativeness as well as the reliability of the GEVATS data constitute a fundamental point of departure for this nationwide cohort


INTRODUCCIÓN: Nuestro estudio buscó conocer el grado de implementación actual de la cirugía toracoscópica asistida por video (VATS, por sus siglas en inglés) para las resecciones pulmonares anatómicas en España. Presentamos nuestros resultados iniciales y describimos los sistemas de auditoría desarrollados por el grupo español de VATS (GEVATS). MÉTODOS: Realizamos un estudio de cohortes prospectivo multicéntrico que incluyó pacientes que fueron tratados con resecciones pulmonares anatómicas entre el 20/12/2016 y el 20/03/2018. Los controles de calidad principales consistieron en determinar la tasa de reclutamiento de cada centro y la precisión de los datos perioperatorios recolectados en base a seis variables clave. Se analizaron las implicaciones de una baja tasa de reclutamiento para "mortalidad a los 90 días" y "complicaciones de grado IIIb-V". RESULTADOS: La serie estaba compuesta por 3533 casos (1917 VATS; 54,3%) en 33 servicios. La mediana de la tasa de reclutamiento de los centros fue del 99% (p25-p75: 76-100%), con una tasa de reclutamiento global del 83% y una precisión de los datos del 98%. No pudimos demostrar una asociación significativa entre la tasa de reclutamiento y el riesgo de morbi-mortalidad, pero se encontró una tendencia en el análisis no ajustado para aquellos centros con tasas de reclutamiento inferiores al 80% (usando los centros con tasas de 95-100% como referencia): OR = 0,61 para el grado IIIb-V (p = 0,081), OR = 0,46 para la mortalidad a los 90 días (p = 0,051). CONCLUSIONES: Más de la mitad de las resecciones pulmonares anatómicas en España se realizan a través de VATS. Según nuestros resultados, la tasa de reclutamiento del centro y sus posibles implicaciones debido al sesgo de selección, deberían recibir más atención por parte de los principales estudios multicéntricos voluntarios de nuestra especialidad. La alta representatividad y la confiabilidad de los datos de GEVATS constituyen un punto de partida fundamental para esta cohorte nacional

ABSTRACT

A Nb-containing siliceous porous clay heterostructure (PCH) with Nb contents from 0 to 30 wt %) was prepared from a bentonite and used as support in the preparation of supported NiO catalysts with NiO loading from 15 to 80 wt %. Supports and NiO-containing catalysts were characterised by several physicochemical techniques and tested in the oxidative dehydrogenation (ODH) of ethane. The characterisation studies on Nb-containing supports showed the presence of well-anchored Nb5+ species without the formation of Nb2 O5 crystals. High dispersion of nickel oxide with low crystallinity was observed for the Nb-containing PCH supports. In addition, when NiO is supported on these Nb-containing porous clays, it is more effective in the ODH of ethane (ethylene selectivity of ca. 90 %) than NiO supported on the corresponding Nb-free siliceous PCH or on Nb2 O5 (ethylene selectivities of ca. 30 and 60 %, respectively). Factors such as the NiO-Nb5+ interaction, the NiO particle size and the properties of surface Nin+ species were shown to determine the catalytic performance.

ABSTRACT

BACKGROUND: Psychological variables (anxiety, depression, and coping strategies) and asthma control (assessed from the patient's perspective or from the physician's perspective) affect health-related quality of life (HRQoL) in asthmatic patients. However, no study has simultaneously evaluated these variables to understand the independent contribution of each one of these factors to HRQoL. OBJECTIVE: To determine the impact of anxiety, depression, coping strategies, and asthma control on HRQoL, and to compare the impact of asthma control on HRQoL when it is established by the physician versus when it is considered by the patient. METHODS: A total of 373 asthmatics completed the Hospital Anxiety and Depression Scale, Coping Orientations to Problems Experienced Inventory, 36-Item Short-Form Health Survey, and St. George Respiratory Questionnaire. Asthma control was measured by the patient with Asthma Control Test and by the physician with the classification asthma control of Global Initiative for Asthma. Demographic and clinical characteristics were also collected. RESULTS: Anxiety, depression, and poor patient-rated asthma control status were associated with worse HRQoL in all dimensions (except Mental Health for asthma control). Physician-rated asthma control was related to worse HRQoL in physical generic and specific dimensions. Among coping strategies, only avoidant coping impacted HRQoL in a few dimensions. CONCLUSIONS: Anxiety, depression, and asthma control (especially patient-rated asthma control) were important independent predictors of asthma HRQoL, and all of them should therefore be considered in interventions to improve HRQoL in asthmatic patients.

ABSTRACT

Different nickel catalysts have been tested for the transformation of levulinic acid into γ-valerolactone using an easy hydrothermal method, taking advantage of the properties of the high temperature water. A metallic nickel catalyst derived from NiO synthesized by a nanocasting procedure can achieve a productivity to γ-valerolactone, which is two orders of magnitude higher than that obtained by a commercial nickel catalyst. This nanocasted metallic nickel catalyst has shown bifunctionality as it is capable of activating water as the source for hydrogen and undertaking the further hydrogenation step. In contrast with metallic nickel, nickel oxide has shown to be incapable of transforming levulinic acid into γ-valerolactone.

ABSTRACT

OBJECTIVE: To analyze the safety and efficacy of niraparib in patients aged ≥70 years with recurrent ovarian cancer in the ENGOT-OV16/NOVA trial. METHODS: The trial enrolled 2 independent cohorts with histologically diagnosed recurrent ovarian, fallopian tube, or peritoneal cancer who responded to platinum rechallenge, on the basis of germline breast cancer susceptibility gene mutation (gBRCAmut) status. Patients were randomized 2:1 to receive niraparib (300 mg) or placebo once daily until disease progression. The primary endpoint was progression-free survival (PFS) by blinded independent central review. Adverse events (AEs) of special interest were based on the known safety profile of poly(ADP-ribose) polymerase inhibitors. RESULTS: Patients aged ≥70 years in the gBRCAmut cohort receiving niraparib (n = 14) had not yet reached a median PFS compared with a median PFS of 3.7 months for the same age group in the placebo arm (hazard ratio [HR], 0.09 [95% confidence interval (CI), 0.01 to 0.73]). Non-gBRCAmut patients aged ≥70 years receiving niraparib (n = 47) had a median PFS of 11.3 months compared with 3.8 months in the placebo arm (HR, 0.35 [95% CI, 0.18 to 0.71]). Median duration of follow-up in the niraparib arm was 17.3 months in patients ≥70 years and 17.2 months in patients <70 years. Frequency, severity of AEs, and dose reductions in the niraparib arm were similar in patients aged <70 and ≥ 70 years population. The most common grade ≥ 3 AEs in patients ≥70 years were hematologic: thrombocytopenia event (34.4%), anemia event (13.1%), and neutropenia event (16.4%). CONCLUSIONS: For patients ≥70 years of age receiving niraparib as maintenance treatment in the ENGOT-OV16/NOVA trial, PFS benefits and incidence of any grade or serious treatment-emergent AEs were comparable to results in the younger population. Use of niraparib should be considered in this population.

ABSTRACT

Bosutinib is a second-generation tyrosine kinase inhibitor (2GTKI) approved at 400 mg once daily (QD) as first-line therapy in patients with chronic myeloid leukemia (CML) patients and at 500 mg QD in patients who are resistant to or intolerant of prior therapy. In clinical practice, bosutinib is often given to patients who have failed imatinib, nilotinib, and dasatinib (i.e., as fourth-line treatment), despite the limited data on its clinical benefit in this setting. We have retrospectively evaluated the results of bosutinib in a series of 62 CML patients who have failed to prior treatment with all three, imatinib, nilotinib, and dasatinib. Median time on TKI treatment before bosutinib start was 105 (9-163) months, and median duration on bosutinib was 9 months (1-30). Overall, probabilities to achieve complete cytogenetic response (CCyR) and major molecular response (MMR) were 25% and 24% respectively. After a median follow-up period of 14 months, the event-free survival and progression-free survival were 68 and 85%, respectively. Sixty-four percent of patients in CCyR at the time of bosutinib start were able to achieve MMR. In contrast, patients without CCyR, probabilities to obtain CCyR and MMR were 25% and 14%. Bosutinib was well tolerated in this heavily pretreated patients' cohort. Pleural effusions and diarrhea were the most frequent grade II-IV side effects, leading to treatment discontinuation in 16% of patients. Bosutinib is an effective treatment option for patients who have failed previous 2GTKIs due to intolerance. However, efficacy seems to be related to the molecular response that the patient achieved prior to bosutinib.

ABSTRACT

Ferric chloride solutions are used as coagulants or flocculants in water treatment operations for human consumption. This treatment produces large amounts of clay-type solids formed mainly of montmorillonite with iron oxides and humic substances. This ferric sludge can be used as an efficient catalyst for the removal of volatile organic compounds (VOCs) by total oxidation. This waste isolated in the purification process has been activated by calcinations in air, characterized by several physicochemical techniques and employed as a catalyst for the removal by total oxidation of representative VOCs: toluene, propane and mixtures of toluene/propane with or without water. This ferric sludge has shown a catalytic activity one order of magnitude higher than that of a commercial iron oxide. This high activity has been related to the composition of the sludge (as it contains active metal oxides such as oxides of iron and manganese) and to the porous structure (leading to a reasonably high surface area). Moreover, it can be also used as a support for platinum, showing comparable (or even higher) catalytic activity than a similar platinum catalyst supported on conventional γ-alumina. This work presents a double environmental perspective since the material employed as a catalyst is a waste sludge and the catalytic reaction studied deals about the elimination of pollutants.

ABSTRACT

BACKGROUND: Quality of life (QOL) has become an important complementary endpoint in cancer clinical studies alongside more traditional assessments (eg, tumour response, progression-free survival, overall survival). Niraparib maintenance treatment has been shown to significantly improve progression-free survival in patients with recurrent ovarian cancer. We aimed to assess whether the benefits of extending progression-free survival are offset by treatment-associated toxic effects that affect QOL. METHODS: The ENGOT-OV16/NOVA trial was a multicentre, double-blind, phase 3, randomised controlled trial done in 107 study sites in the USA, Canada, Europe, and Israel. Patients with recurrent ovarian cancer who were in response to their last platinum-based chemotherapy were randomly assigned (2:1) to receive either niraparib (300 mg once daily) as a maintenance treatment or placebo. Randomisation was stratified based on time to progression after the penultimate platinum-based regimen, previous use of bevacizumab, and best response (complete or partial) to the last platinum-based regimen with permuted-block randomisation (six in each block) using an interactive web response system. The trial enrolled two independent cohorts on the basis of germline BRCA (gBRCA) mutation status (determined by BRACAnalysis Testing, Myriad Genetics, Salt Lake City, UT, USA). The primary endpoint of the trial was progression-free survival, and has already been reported. In this study, we assessed patient-reported outcomes (PROs) in the intention-to-treat population using the Functional Assessment of Cancer Therapy-Ovarian Symptoms Index (FOSI) and European QOL five-dimension five-level questionnaire (EQ-5D-5L). We collected PROs from trial entry every 8 weeks for the first 14 cycles and every 12 weeks thereafter. If a patient discontinued, we collected PROs at discontinuation and during a postprogression visit 8 weeks (plus or minus 2 weeks) later. We assessed the effect of haematological toxic effects on QOL with disutility analyses of the most common grade 3-4 adverse events (thrombocytopenia, anaemia, and neutropenia) using a mixed model with histology, region, previous treatment, age, planned treatment, and baseline score as covariates. This study is registered with ClinicalTrials.gov, number NCT01847274. FINDINGS: Between Aug 28, 2013, and June 1, 2015, 553 patients were enrolled and randomly assigned to receive niraparib (n=138 in the gBRCAmut cohort, n=234 in the non-gBRCAmut cohort) or placebo (n=65 in the gBRCAmut cohort, n=116 in the non-gBRCAmut cohort). The mean FOSI score at baseline was similar between the two groups (range between 25·0-25·6 in the two groups). Overall QOL scores remained stable during the treatment and preprogression period in the niraparib group; no significant differences were observed between the niraparib and placebo group, and preprogression EQ-5D-5L scores were similar between the two groups in both cohorts (0·838 [0·0097] in the niraparib group vs 0·834 [0·0173] in the placebo group in the gBRCAmut cohort; and 0·833 [0·0077] in the niraparib group vs 0·815 [0·0122] in the placebo group in the non-gBRCAmut cohort). The most common adverse events reported at screening (baseline) were lack of energy (425 [79%]; 97 [18%] reporting severe lack of energy), pain (236 [44%]), and nausea (118 [22%]). All symptoms, except nausea, either remained stable or improved over time in the niraparib group. The most common grade 3 or 4 toxicities observed in the niraparib group were haematological in nature: thrombocytopenia (124 [34%] of 367 patients), anaemia (93 [25%]), and neutropenia (72 [20%]); disutility analyses showed no significant QOL impairment associated with these toxic effects. INTERPRETATION: These PRO data suggest that women who receive niraparib as maintenance treatment for recurrent ovarian cancer after responding to platinum treatment are able to maintain QOL during their treatment when compared with placebo.

ABSTRACT

PURPOSE: Prior studies suggest that specialist care associates with improved health-related quality of life (HRQL) in asthmatic patients. However, there are limited studies focused on differences in HRQL among subspecialties. The aim of this study was to assess the differences in HRQL between adult asthmatic patients treated in pneumology or allergy practices, and to estimate to what extent the differences in HRQL can be explained by sociodemographic, clinical or psychological characteristics of patients from each specialty. METHODS: We recruited adult asthmatic outpatients from allergy and pneumology practices. Information on sociodemographic, clinical and psychological characteristics was collected, and HRQL was assessed with generic and disease-specific questionnaires. HRQL was compared between groups adjusting for sociodemographic, clinical and psychological characteristics. RESULTS: A total of 287 asthmatic patients participated in the study (105 from pneumology and 182 from allergy). Patients treated by pneumologists reported significantly poorer HRQL in physical dimensions of generic questionnaire and all dimensions of disease-specific questionnaire. Pneumology patients were older (p < .001) and had a lower education level (p < .001); a higher number of patients were in a non-active employment situation (p = .003) and had worse pulmonary function (p < .001), longer duration of disease (p = .020), higher prevalence of obesity (p < .001) and uncontrolled asthma (p < .001), and a higher rate of previous absenteeism (p = .001). Depression and the use of cognitive avoidance coping were also higher among pneumology patients (p = .050 and p = .022, respectively). There were not significant differences in HRQL between pneumology and allergy patients after adjustment for these sociodemographic, clinical and psychological characteristics. CONCLUSIONS: Asthmatic patients treated by pneumologists reported poorer HRQL than patients treated by allergists, but this outcome is attributed to differences in several sociodemographic, clinical and psychological characteristics between the two groups of patients.

ABSTRACT

The introduction of trastuzumab therapy markedly improved the poor prognosis associated with HER2-amplified breast cancers. Despite this, the presence of primary and acquired resistance to trastuzumab treatment remains a significant common challenge. The identification of resistance mechanisms and the incorporation of new drugs that achieve a better blockade of HER family receptors signaling have resulted in improved outcomes. The phosphatidylinositol 3'-kinase/protein kinase B/mammalian target of rapamycin pathway, cross-talk with estrogen receptors, immune response, cell cycle control mechanisms, and other tyrosine kinase receptors such as insulin-like growth factor I receptor are potential pathways involved in trastuzumab resistance. Different therapeutic interventions targeting these pathways are currently under evaluation.

ABSTRACT

BACKGROUND: Despite well-known risk factors and predictive survival models, many patients with cystic fibrosis (CF) die while on the waiting list for lung transplant. We evaluated whether specific Cystic Fibrosis Questionnaire (CFQ-R) scales provide additional benefit to conventional tools in identifying referral timing and waitlist mortality. METHODS: From January 2010 to January 2015, 152 patients (34% on the waitlist) were evaluated with the CFQ-R and standard protocol quarterly. Data were used to explore the prognostic association of health-related quality of life. RESULTS: The Physical Functioning domain (PFD) of the CFQ-R predicted mortality in advanced CF disease better than habitual parameters (p = 0.005). For patients with the same forced expiratory volume in 1 sec (FEV1), a low score categorized patients with an increased risk of death. For patients with CF and FEV1 <30% predicted and a low Physical score, mortality rate was ~35% at 2 years. The best model for probability of inclusion on the waitlist was FEV1 % (p < 0.001, hazard ratio [HR] = 0.94; 95% confidence interval [CI] [0.90, 0.97]) and Physical Functioning (p = 0.013, HR = 0.96; 95% CI [0.95, 0.99]). The best model for probability of death similarly included FEV1 % (p = 0.09, HR = 0.97; 95% CI [0.94, 1.00]) and CFQ-R Physical Functioning score (p = 0.005, HR = 0.97; 95% CI [0.95, 0.99]). The Health Perception score showed similar results. A low Health Perception score combined with a high resting heart rate showed a trend for mortality. CONCLUSIONS: The CFQ-R may be an additional tool for guiding decisions to place a patient with CF on the waiting list for lung transplantation. The CFQ-R Physical Functioning and Health Perception scales were more accurate than conventional tools in predicting death before transplant.

ABSTRACT

La esclerosis lateral amiotrófica (ELA) es una enfermedad neurodegenerativa con una incidencia de 1-2 casos por 100.000 habitantes/año y una prevalencia de 4-6 casos por 100.000 habitantes (3,5 casos por 100.000 habitantes en España). La mayoría de los casos de ELA son esporádicos, pero el 5-10 % son familiares con herencia autosómica dominante. La edad media de aparición para ELA esporádica es alrededor de los 60 años. El objetivo del presente estudio de casos ha sido analizar la importancia del papel del médico de atención primaria en la sospecha diagnóstica, derivación, seguimiento y acompañamiento del paciente con ELA y su familia. Para ello se han analizado dos casos clínicos de los tipos más característicos de ELA y las actuaciones de los médicos de atención primaria que los han atendido, reflejando que una mayor difusión de los síntomas y signos de ELA podrían contribuir a un diagnóstico más precoz y con mayor grado de certeza (AU)


Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease with an incidence of 1 - 2 cases per 100,000 persons/year, and a prevalence of 4-6 cases per 100,000 population (3.5 cases per 100,000 population in Spain). Most ALS cases are sporadic but 5-10 % of cases are familial with autosomal dominant inheritance. The average age of onset for sporadic ALS is about 60 years. The objective of this case study was to analyze the importance of the role of the Primary Care Doctor in the presumptive diagnosis, referral, monitoring and support of patients with ALS and their families. To that end, we analyzed two clinical cases of the most characteristic types of ALS and the intervention of the attending Primary Care doctors, reflecting that a wider dissemination of the signs and symptoms of ALS may contribute to earlier diagnosis and greater degree of certainty (AU)
