RESUMO
Ecosystem structure and function are increasingly threatened by changing climate, with profound effects observed globally in recent decades. Based on standardized visual censuses of reef biodiversity, we describe 27 years of community-level change for fishes, mobile macroinvertebrates and macroalgae in the Tasmanian ocean-warming hotspot. Significant ecological change was observed across 94 reef sites (5-10 m depth range) spanning four coastal regions between three periods (1992-95, 2006-07, 2017-19), which occurred against a background of pronounced sea temperature rise (+0.80°C on average). Overall, fish biomass increased, macroinvertebrate species richness and abundance decreased and macroalgal cover decreased, particularly during the most recent decade. While reef communities were relatively stable and warming was slight between the 1990s and mid-2000s (+0.12°C mean temperature rise), increased abundances of warm affinity fishes and invertebrates accompanied warming during the most recent decade (+0.68°C rise). However, significant rises in the community temperature index (CTI) were only found for fishes, invertebrates and macroalgae in some regions. Coastal warming was associated with increased fish biomass of non-targeted species in fished zones but had little effect on reef communities within marine reserves. Higher abundances of larger fishes and lobsters inside reserves appeared to negate impacts of 'thermophilization'.

El principio básico de la fecundación in vitro en ciclo natural (FIV-CN) recae en el reclutamiento mediante la selección folicular espontánea, minimizando la manipulación del ciclo de la mujer. Recientemente esta técnica ha suscitado mayor interés y se han puesto en valor muchas de sus ventajas respecto a la FIV convencional (FIVc). FIV-CN y FIVc son tratamientos complementarios que permiten ampliar el espectro terapéutico en las parejas con indicación de FIV. La FIV-CN constituye un tratamiento a considerar especialmente en la paciente con mal pronóstico para la FIVc por baja reserva ovárica. La edad es su principal factor pronóstico y los resultados son aceptables hasta los 40 años. El principal factor limitante de la FIV-CN es el riesgo de cancelación por ovulación, que puede reducirse mediante diferentes estrategias. No obstante, los resultados por transferencia embrionaria son satisfactorios en diferentes series publicadas.
The basic principle of natural cycle in vitro fertilization (NC-IVF) lies in recruitment through spontaneous follicular selection, avoiding or minimizing the use of drugs and manipulation of the woman's cycle. In recent years, this technique has attracted growing interest and many of its advantages over conventional IVF (cIVF) have been highlighted. NC-IVF and cIVF should be considered complementary treatments, which broaden the therapeutic spectrum for couples for whom IVF is indicated. NC-IVF could be considered in patients with poor prognosis for cIVF due to low ovarian reserve. Age is the main prognostic factor and results are acceptable up to 40 years of age. The main limiting factor is the risk of cancellation due to ovulation, which can be reduced through different strategies. Pregnancy rate per embryo transfer results are encouraging.

Introduction Stage IV rectal cancer with resectable disease presents challenging issues, as the radical treatment of the whole disease is difficult. Surgery and chemotherapy (CT) play an unquestionable role, but the contribution of pelvic radiotherapy (RT) is not very clear. Methods In 2009, we established a prospective treatment protocol that included CT, short-course preoperative radiotherapy (SCRT) with surgery of the primary tumour and all metastatic locations. Results Forty patients were included. Eight (20%) patients did not receive CT due to significant comorbidities. Radical surgery treatment was possible in 22 (55%) patients. The mean follow-up was 42.81 months (3.63105.97). Overall survival at 24 and 36 months was 71.4% and 58.2%, respectively. There was good local control of the disease, as 97.2% of pelvic surgeries were R0 and there were no local recurrences. Conclusion In stage IV with resectable metastatic disease, the proposed therapeutic regimen seems very appropriate in well selected patients able to tolerate the treatment. We bet on the role of pelvic RT, due to the good local control of the disease in our series (AU)

OBJETIVO: Conocer la relación entre el nivel de independencia de un grupo de ancianos crónicos-pluripatológicos y paliativos (ACP-P) y la sobrecarga de sus cuidadores, tras un programa de entrenamiento multicomponente adaptado al ámbito domiciliario. DISEÑO: mixto, cuantitativo y cuasiexperimental, con medidas repetidas en el factor Entrenamiento, y dos factores de agrupación: edad (70-79 y ≥80 años) y nivel de deambulación del ACP-P (anda/no anda). EMPLAZAMIENTO: Intervención realizada en la Unidad de Hospitalización a Domicilio (UHD) del Hospital General de Alicante, durante 2014-2016. PARTICIPANTES: 17 pacientes ACP-P, edad media 81,6 años (DE 5,6). Intervención. 3 sesiones semanales durante 26 semanas del programa de entrenamiento funcional-cognitivo EFAM-UVH(c); 3 fases, reduciendo progresivamente la presencia del entrenador para fomentar la autonomía (28 sesiones supervisadas y 20 autónomas en total). MEDICIONES PRINCIPALES: Evaluación de Sobrecarga del cuidador (Zarit) y Nivel de independencia (Índice de Barthel "IB"), apoyados por indicadores fisiológicos y funcionales. RESULTADOS: IB mejoró con el entrenamiento supervisado (p < 0,05), y se mantuvo o descendió leve, aunque no significativamente, al aumentar la autonomía. Estas mejoras se acompañaron de una reducción en la sobrecarga del cuidador, con una dinámica similar, fundamentalmente en cuidadores del grupo <79 años y de los que no andan. No se encontró relación entre IB y Zarit, pero los deltas de ambas variables se asociaron en las fases supervisadas (r=-0,596, p = 0,015), reflejando el impacto del ejercicio. CONCLUSIONES: El entrenamiento multicomponente ayuda a contener la sobrecarga del cuidador, reducida de forma concomitante al aumento de independencia del ACP-P entrenado. Este beneficio indirecto potencia la necesidad de equipos multidisciplinares y programas de ejercicio temprano y supervisado
OBJECTIVE: To know the relationship between the level of independence of a group of chronic-pluripatological and palliative elders (ACP-P) and the overload of their caregivers, after a multicomponent training program adapted to the home environment. DESIGN: Mixed, quantitative and quasi-experimental design, with repeated measures in the training factor, and two grouping factors: age (70-79 and ≥80 years) and the ambulation level of the ACP-P (walk /don't walk). LOCATION: Intervention carried out in the Home Hospitalization Unit (HHU) of the General Hospital of Alicante, during 2014-2016. PARTICIPANTS: 17 ACP-P patients [81.6 years (SD5.6)]. INTERVENTION: 3 weekly sessions for 26 weeks of the EFAM-UVH(c) multicomponent training program (functional + cognitive); 3 phases, progressively reducing the presence of the coach to promote autonomy (28 supervised and 20 autonomous sessions in total). MAIN MEASUREMENTS: Evaluation of caregiver overload (Zarit) and level of independence (Barthel Index "BI") of the ACP-P, supported by physiological and functional indicators. RESULTS: BI improved with supervised training (p < 0.05), and remained or fell slightly, although not significantly, when increasing the autonomy. These improvements were accompanied by a reduction in the overload of the caregiver, with a similar dynamic, mainly in the caregivers of the group <79 years and those who do not walk. No relationship was found between IB and Zarit, but the deltas of both variables were associated in the supervised phases (r = -0.596, p = 0.015), reflecting the impact of physical exercise. CONCLUSIONS: Multicomponent exercise training at the HHU helps to contain the caregiver's overload, reduced concomitantly to the increased of independence of the trained ACP-P. This indirect benefit maximizes the need of multidisciplinary teams, and early and supervised physical exercise training programs

BACKGROUND: Systemic lupus erythematosus (SLE) is regarded as a prototype autoimmune disease because it can serve as a means for studying differences between ethnic minorities and sex. Traditionally, all Hispanics have been bracketed within the same ethnic group, but there are differences between Hispanics from Spain and those from Latin America, not to mention other Spanish-speaking populations. OBJECTIVES: This study aimed to determine the demographic and clinical characteristics, severity, activity, damage, mortality and co-morbidity of SLE in Hispanics belonging to the two ethnic groups resident in Spain, and to identify any differences. METHODS: This was an observational, multi-centre, retrospective study. The demographic and clinical variables of patients with SLE from 45 rheumatology units were collected. The study was conducted in accordance with Good Clinical Practice guidelines. Hispanic patients from the registry were divided into two groups: Spaniards or European Caucasians (EC) and Latin American mestizos (LAM). Comparative univariate and multivariate statistical analyses were carried out. RESULTS: A total of 3490 SLE patients were included, 90% of whom were female; 3305 (92%) EC and 185 (5%) LAM. LAM patients experienced their first lupus symptoms four years earlier than EC patients and were diagnosed and included in the registry younger, and their SLE was of a shorter duration. The time in months from the first SLE symptoms to diagnosis was longer in EC patients, as were the follow-up periods. LAM patients exhibited higher prevalence rates of myositis, haemolytic anaemia and nephritis, but there were no differences in histological type or serositis. Anti-Sm, anti-Ro and anti-RNP antibodies were more frequently found in LAM patients. LAM patients also had higher levels of disease activity, severity and hospital admissions. However, there were no differences in damage index, mortality or co-morbidity index. In the multivariate analysis, after adjusting for confounders, in several models the odds ratio (95% confidence interval) for a Katz severity index >3 in LAM patients was 1.45 (1.038-2.026; p = 0.02). This difference did not extend to activity levels (i.e. SLEDAI >3; 0.98 (0.30-1.66)). CONCLUSION: SLE in Hispanic EC patients showed clinical differences compared to Hispanic LAM patients. The latter more frequently suffered nephritis and higher severity indices. This study shows that where lupus is concerned, not all Hispanics are equal.

Introduction: Geriatric oncology (GO) is a discipline that focuses on the management of elderly patients with cancer. The Spanish Society of Medical Oncology (SEOM) created a Working group dedicated to geriatric oncology in February 2016. Objectives: The main goal of this study was to describe the current situation in Spain regarding the management of elderly cancer patients through an online survey of medical oncologists. Methods: A descriptive survey was sent to several hospitals by means of the SEOM website. A personal e-mail was also sent to SEOM members. Results: Between March 2016 and April 2017, 154 answers were collected. Only 74 centers (48%) had a geriatrics department and a mere 21 (14%) medical oncology departments had a person dedicated to GO. The vast majority (n = 135; 88%) had the perception that the number of elderly patients with cancer seen in clinical practice had increased. Eighteen (12%) oncologists had specific protocols and geriatric scales were used at 55 (31%) centers. Almost all (92%) claimed to apply special management practices using specific tools. There was agreement that GO afforded certain potential advantages. Finally, 99% of the oncologists surveyed believed it and that training in GO had to be improved. Conclusions: From the nationwide survey promoted by the Spanish Geriatric Oncology Working Group on behalf of SEOM, we conclude that there is currently no defined care structure for elderly cancer patients. There is an increasing perception of the need for training in GO. This survey reflects a reality in which specific needs are perceived

Cancer of unknown primary site is a histologically confirmed cancer that manifests in advanced stage, with no identifiable primary site following standard diagnostic procedures. Patients are initially categorized based on the findings of the initial biopsy: adenocarcinoma, squamous-cell carcinoma, neuroendocrine carcinoma, and poorly differentiated carcinoma. Appropriate patient management requires understanding several clinical and pathological features that aid in identifying several subsets of patients with more responsive tumors (AU)

Background: Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following: ⢠Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy with small diameter endoscopes. ⢠Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability. ⢠Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour threshold, and/or one of odour identification or discrimination. ⢠Comprehensive chemosensory assessment should include gustatory screening. ⢠Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions: We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

RESUMO
Somatic mutations in the CALR gene were recently discovered in a substantial proportion of Philadelphia-negative chronic myeloproliferative neoplasm (cMPN) patients lacking JAK2 and MPL mutations. Somatically acquired defects are not the only pathogenic mechanism involved in these disorders. Since germline JAK2 46/1 haplotype predisposes to cMPN-associated mutations, including JAK2V617F and MPLW515K7L, we evaluated whether the 46/1 haplotype also confers susceptibility to CALR-mutated cMPN, both in sporadic and familial cases. The single-nucleotide polymorphism rs10974944, which tags 46/1, was investigated in 155 sporadic MPN patients and 270 unrelated controls, as well as in 11 familial cMPN cases and 36 unaffected relative controls. As described elsewhere, the 46/1 haplotype was overrepresented, both in sporadic and familial cMPN. In sporadic cMPN, the JAK2 46/1 haplotype was closely associated with JAK2V617F (p = 0.0003) but not with JAK2-nonmutated cases. Analysis of CALR-mutated sporadic cMPN (n = 22) showed no association between CALR mutations and 46/1 haplotype (p = 0.87). Regarding the familial cMPN, the prevalence of carriers of the G allele was higher in familial (81.8%) than in sporadic (62%) cMPN, but it did not differ significantly (p = 0.3). Although we described a family with carriers of both JAK2V617F and CALR mutations, due to the low number of CALR-mutated familial cases, we could not determinate whether the JAK2 46/1 haplotype predisposes or does not to CALR-mutated familial cMPN. We conclude, for the first time, that the 46/1 haplotype, unlike JAK2V617F and MPLW515K7L, is not associated with CALR-mutated cMPN.

BACKGROUND: The development of intestinal transplant (Tx) programs introduces thymoglobulin donor treatment as well as an almost complete warm dissection of the abdominal organs to allocate them to different recipients. Our aim is to assess the reproducibility and feasibility of the surgical technique of multi-organ procurement with the use of thymoglobulin donor pre-treatment and report the short- and long-term outcomes of every graft harvested as part of multi-organ procurement (MTOp), including the intestine. METHODS: Data were collected of all organs harvested from MTOp, including the intestines allocated to our center from March 2006 to July 2011. Data from 92 recipients and 116 organs procured from 29 MTOp were analyzed. Twelve hearts, 2 lungs, and 1 cardio-pulmonary block were transplanted; primary graft dysfunction developed in 4 of the 12 hearts and in the cardio-pulmonary block. RESULTS: The survival rate was 75% and 100% for hearts and lungs, respectively. Nineteen livers, 9 kidney-pancreas, 19 kidneys, and 29 intestines were transplanted. Delayed graft function (DGF) of the pancreas developed in 3 of 9 kidney-pancreas, and the other 3 exhibited DGF of the kidney; 4 of 19 Tx kidneys had DGF. The survival was 84%, 78%, 95%, and 65.5% for livers, kidney-pancreas, kidneys, and intestines, respectively. CONCLUSIONS: Organs procured during MTOp including the intestine can be safely used, increasing organ availability and transplant applicability without compromising allocation, quality, and long-term results of the non-intestinal-procured organs.

The purpose of this study was to assess the clinical effects of dexmedetomidine, both alone and combined with pethidine or butorphanol, in cats. A prospective randomized blind study was performed. Thirty cats were randomly assigned to three groups of 10 animals: D: dexmedetomidine (20 µg/kg IM); DP: dexmedetomidine (10 µg/kg IM) and pethidine (2.5 mg/kg IM); DB: dexmedetomidine (10 µg/kg IM) and butorphanol (0.4 mg/kg IM). Quality of sedation, analgesia, muscle relaxation and the possibility of performing some clinical procedures were compared using a multifactorial scale. Sedation, analgesia and muscle relaxation increased progressively over time and did not differ in the three protocols. The three protocols facilitated the completion of several clinical procedures. The clinical variables studied showed a similar behaviour in the three protocols and remained close to the baseline, except for a drop in heart rate in protocol D. In conclusion, dexmedetomidine, either alone or combined with pethidine or butorphanol, offers suitable sedation, analgesia and relaxation to perform various clinical procedures in cats.

AIM: Adjuvant 5-fluorouracil based chemotherapy has demonstrated benefit in Stage III colon cancer but still remains controversial in Stage II. The aim of this study was to analyse the prognostic impact of clinicopathological factors that may help guide treatment decisions in Stage II colon cancer. METHOD: Between 1996 and 2006 data from patients diagnosed with colorectal cancer at Hospital Universitari Bellvitge and its referral comprehensive cancer centre Institut Català d'Oncologia/L'Hospitalet were prospectively included in a database. We identified 432 patients with Stage II colon cancer operated on at Hospital Universitari Bellvitge. The 5-year relapse-free survival (RFS) and colon-cancer-specific survival (CCSS) were determined. RESULTS: The 5-year RFS and CCSS were 83% and 88%, respectively. Lymphovascular or perineural invasion was associated with RFS [hazard ratio (HR) 1.84; 95% CI 1.01-3.35]. Gender (women, HR 0.48; 95% CI 0.23-1) and lymphovascular or perineural invasion (HR 3.51; 95% CI 1.86-6.64) together with pT4 (HR 2.79; 95% CI 1.44-5.41) influenced CCSS. In multivariate analysis pT4 and lymphovascular or perineural invasion remained significantly associated with CCSS. We performed a risk index with these factors with prognostic impact. Patients with pT4 tumours and lymphovascular or perineural invasion had a 5-year CCSS of 61%vs the 93% (HR 5.87; 95 CI 2.46-13.97) of those without any of these factors. CONCLUSION: pT4 and lymphatic, venous or perineural invasion are confirmed as significant prognostic factors in Stage II colon cancer and should be taken into account in the clinical validation process of new molecular prognostic factors.

The anaesthetic records of 1525 dogs were examined to determine the prevalence of postanaesthetic hypothermia, its clinical predictors and consequences. Temperature was recorded throughout the anaesthesia. At the end of the procedure, details coded in were: hyperthermia (>39.50°C), normothermia (38.50°C-39.50°C), slight (38.49°C-36.50°C), moderate (36.49°C-34.00°C) and severe hypothermia (<34.00°C). Statistical analysis consisted of multiple regression to identify the factors that are associated with the temperature at the end of the procedure. Before premedication, the temperature was 38.7 ± 0.6°C (mean ± sd). At 60, 120 and 180 minutes from induction, the temperature was 36.7 ± 1.3°C, 36.1 ± 1.4°C and 35.8 ± 1.5°C, respectively. The prevalence of hypothermia was: slight, 51.5 per cent (95 per cent CI 49.0 to 54.0 per cent); moderate, 29.3 per cent (27.1-31.7 per cent) and severe: 2.8% (2.0-3.7%). The variables that associated with a decrease in the temperature recorded at the end of the anaesthesia were: duration of the preanesthetic time, duration of the anaesthesia, physical condition (ASA III and ASA IV dogs showed lower temperatures than ASA I dogs), the reason for anaesthesia (anaesthesia for diagnostic procedures or thoracic surgery reduce the temperature when compared with minor procedures), and the recumbency during the procedure (sternal and dorsal recumbencies showed lower temperatures than lateral recumbency). The temperature before premedication and the body surface (BS) were associated with a higher temperature at the end of the anaesthesia, and would be considered as protective factors.

Here we describe the application of new and existing multiplex PCR methodologies for shark species molecular identification. Four multiplex systems (group ID, thresher sharks, hammerhead sharks and miscellaneous shark) were employed with primers previously described and some designed in this study, which allow for species identification after running PCR products through an agarose gel. This system was implemented for samples (bodies and fins) collected from unidentified sharks landed in the port of Buenaventura and from confiscated tissues obtained from illegal fishing around the Malpelo Island Marine Protected Area, Pacific Coast of Colombia. This method has allowed reliable identification, to date, of 407 samples to the genus and/or species levels, most of them (380) identified as the pelagic thresher shark (Alopias pelagicus). Another seven samples were identified as scalloped hammerhead sharks (Sphyrna lewini). This is an easy-to-implement and reliable identification method that could even be used locally to monitor shark captures in the main fishing ports of developed and developing countries.
