Risk of cancer-related distress by age in colorectal cancer survivors: The modulatory role of unmet support needs.

To explore the modulating role of unmet support needs on the relationship between age and the prevalence of cancer-related distress in colorectal cancer (CRC) survivors. Two hundred and forty four participants completed the questionnaires; linear regression and odd ratios were calculated. Both the prevalence of needs and their interaction with age were predictors of cancer-related distress. The risk of significant clinically distress associated with physical and socio/family needs was high in both age subgroups. Higher risk of clinical distress was associated with life perspective, sexual, occupational and health care needs in the younger subgroup and with needs for specific support resources in the older subgroup. In reducing cancer-related distress, two key issues arise: (i) the importance of managing the persistent negative symptoms following CRC treatment in survivors of any age and (ii) the need for a differentiated attention to other care needs based on the survivor's age.

Purtscher-like retinopathy following carotid angioplasty and stenting in the treatment of severe carotid stenosis.

We present a case of Purtscher-like retinopathy (PLR) following carotid angioplasty and stenting (CAS). A 56-year-old man with a history of severe stenosis of the left carotid artery and treated by CAS refers acute and painless visual loss on the left eye (OS) 48 h after the procedure. Funduscopic examination showed cotton wool spots and intraretinal hemorrhages confined to the peripapillary and posterior pole of the OS. The optical coherence tomography (OCT) showed retinal thickening and hyperintense lesions in the inner nuclear layer retina.

Glaucoma neovascular causado por metástasis de carcinoma microcítico de pulmón. Presentación de un caso / Neovascular glaucoma caused by small-cell lung cancer iris metastasis: A case presentation

El carcinoma microcítico de pulmón puede afectar al ojo directamente mediante proliferación metastásica o indirectamente a través de síndromes paraneoplásicos. La coroides es el lugar más afectado entre las metástasis uveales; no obstante, el iris puede estar envuelto en una proporción pequeña de casos (<10%). Visión borrosa, dolor, hiperemia, fotofobia, glaucoma, hipema o defectos en el campo visual pueden originarse por la afectación metastásica. La mediana de supervivencia en pacientes con metástasis iridianas es de 4 meses. El glaucoma secundario que se origina puede ser manejado con tratamiento tópico y oral, ciclo fotoablación transescleral, trabeculoplastia con láser, anti-VEGF, MIGS, cirugía filtrante o enucleación. Se presenta un caso único que desarrolló un cáncer microcítico de pulmón primario con metástasis iridianas. Las metástasis provocaron un cierre angular, refractario al tratamiento tópico. Se realizó radioterapia local para conseguir una respuesta local (AU)

Small-cell lung cancer may directly affect the eye by metastatic proliferation or indirectly by paraneoplastic syndromes. The choroid is the most common site for uveal metastasis (90%); however, the iris can be involved in a smaller proportion of cases (incidence <10%). Blurred vision, pain, redness, photophobia, glaucoma, hyphema and visual field defects can arise from this metastatic involvement. The median survival time for patients with iris metastasis is reported to be 4 months. Secondary glaucoma can be managed with topical and oral treatment, transscleral cyclophotocoagulation, laser trabeculoplasty, anti-VEGF, minimally invasive glaucoma surgery (MIGS), filtering surgery, shunting surgery or enucleation. A case of primary small-cell lung cancer with iris metastasis is presented. The metastases produced an angle-closure glaucoma, which was refractory to topical treatment. Local radiotherapy was administered, obtaining a good local response (AU)

Exploring the independent association of employment status to cancer survivors' health-related quality of life.

BACKGROUND: Having a job has been associated with better Health-Related Quality of Life (HRQOL) in cancer survivors. However, the sociodemographic and disease-related profiles characterizing the survivors being employed and those having better HRQOL largely overlap. The present study aims to discern the degree to which employment status is independently associated with cancer survivors' HRQOL or if it mainly reflects the impact of other sociodemographic and cancer-related variables. METHODS: Cross-sectional study on a heterogeneous sample of 772 working-age survivors of adult-onset cancer. An instrument specifically designed to assess HRQOL in cancer survivors and Multivariate Variance Analysis (MANOVA) were used. RESULTS: Survival phase, cancer type, and employment status showed the main effects on cancer survivors' HRQOL. In particular, being employed (vs unemployed) had the greatest positive association with HRQOL, affecting ten of the twelve HRQOL domains considered. Also, interaction effects highlighted the role of age (younger) and marital status (single) as risk factors for a greater negative impact of variables affecting the survivor's HRQOL. CONCLUSIONS: The application of a multivariate methodology sheds new light on two relevant issues for the cancer survivor's HRQOL: (i) the existence of differences between diagnostic groups that are not attributed to other variables such as sex, and (ii) the important and independent role that employment status plays. Comprehensive cancer survivorship care should focus more on high-risk groups and include having a job as an essential aspect to consider and prompt. The fact that the employment status is susceptible to change represents a valuable opportunity to care for the wellbeing of this population.

Cryopreservation of testicular tissue from the dog (Canis familiaris) and wild boar (Sus scrofa) by slow freezing and vitrification: Differences in cryoresistance according to cell type.

Sperm cryopreservation is the most common procedure used to establish germplasm banks for endangered species - but sometimes sperm cells cannot be obtained. In such cases, freezing testicular tissue may be the only option. The testes contains germ cells at different stages of differentiation, including spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids, and spermatozoa, among which differences in cryoresistance might be expected. The present work compares the viability and DNA integrity of 'rounded' cells, and of elongated spermatids and spermatozoa, from the dog and wild boar, following the cryopreservation of testicular tissue by slow freezing or vitrification. Cell viability was analyzed by PI/SYBR14 staining, and DNA integrity via the TUNEL technique. For wild boar, no significant differences were seen between the two methods with respect to the percentage of viable cells, nor in the percentage of cells with DNA damage. In the dog, the percentage of viable rounded germ cells (65.0 ± 2.4%) was higher (P < 0.05) after vitrification than after slow freezing (45.1 ± 6.7%). No difference was found between the two methods in terms of the viability of elongated cells. For rounded cells, the percentage of intact DNA was greater (P < 0.05) after vitrification (90.5 ± 2.1%) than after slow freezing (42.6 ± 11.0%), while for elongated spermatids and spermatozoa it was higher (P < 0.05) after slow freezing (66.9 ± 6.1%) than after vitrification (50.7 ± 4.5%). Thus, the response to cryopreservation is cell type-, cryopreservation type-, and species-dependent. Vitrification would appear to be the most appropriate method for preserving dog testicular tissue given the associated high cell viability and low degree of DNA fragmentation, while in wild boar, either method might be used.

[Epidemiology of the carbapenemase-producing Enterobacteriaceae spread in a community acute hospital and a non-acute rehabilitation hospital in Madrid]. / Epidemiología de la diseminación de enterobacterias productoras de carbapenemasas en un hospital comarcal y un hospital de media estancia en Madrid.

OBJECTIVE: In Spain, the overall prevalence of carbapenem-resistant Enterobacteriaceae (CRE) is increasing. We describe the epidemiological, clinical and microbiological characteristics features of patients with colonization or infection due to CRE in two hospitals in the north-west of Madrid during two years. One hospital was a community acute hospital and the second one was a non-acute rehabilitation hospital. METHODS: A total of 197 CPE isolates were detected during 2013-2014. Microbiological, epidemiological and clinical data were collected, since the first isolate was found in March 2013. RESULTS: A 33.5% of patients with CRE had symptomatic infection and the remaining 66.5% were colonizations. Klebsiella pneumoniae (87.8%) was the most prevalent species and OXA-48 the most frequent carbapenemase (91.9%). We found intra-interhospital spread and some differences in the epidemiology of CRE depending on the hospital, such as more genetic variability in the non-acute rehabilitation hospital. CONCLUSIONS: Studying the CRE transmission we founded an increased incidence in a short period of time and a rapid dissemination of strains between both hospitals. This highlights the need to standardize screening measures for potential carriers and infection control programs in our hospitals.

Mitochondria inheritance is a key factor for tolerance to dehydration in wine yeast production.

UNLABELLED: Mitochondria are the cell's powerhouse when organisms are grown in the presence of oxygen. They are also the source of reactive oxygen species that cause damage to the biochemical components of the cell and lead to cellular ageing and death. Under winemaking conditions, Saccharomyces yeasts exclusively have a fermentative metabolism due to the high sugar content of grape must. However, their production as an active dry yeast (ADY) form required aerobic propagation and a dehydration process. In these industrial steps, oxidative stress is particularly harmful for the cell. In this work, we analysed the impact of the mitochondrial genome on oxidative stress response, longevity and dehydration tolerance using the synthetic interspecific hybrids obtained between two S. cerevisiae and S. uvarum strains. The isogenic nature of nuclear DNA of such hybrids allowed us to analyse the impact of mitochondrial DNA for fermentative and oxidative stress conditions. Under grape must conditions, the inheritance of mitochondrial DNA poorly impacted the fermentative performance of interspecific hybrids, unlike the hybrids with S. cerevisiae mitochondrial inheritance, which displayed increased tolerance to oxidative stress and dehydration, and showed an extended chronological longevity when cells were grown with aeration. SIGNIFICANCE AND IMPACT OF THE STUDY: In modern oenology, yeast starters are employed to inoculate grape juice, usually in the form of active dry yeast (ADY). The dehydration process implies stressful conditions that lead to oxidative damage. Other yeast species and interspecific hybrids other than Saccharomyces cerevisiae may be used to confer novel properties to the final product. However, these yeasts are usually more sensitive to drying. Understanding the causes of oxidative stress tolerance is therefore necessary for developing the use of these organisms in industry. This study indicates the impact of mitochondrial DNA inheritance for oxidative stress resistance in an interspecific context using isogenic Saccharomyces cerevisiae × Saccharomyces uvarum hybrids.
