Abstract: Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, and providing food for predators. Their differences in tolerances and short generation times manifest in rapid community responses to change. Macroinvertebrate community composition is an indicator of water quality. In Europe, efforts to improve water quality following environmental legislation, primarily starting in the 1980s, may have driven a recovery of macroinvertebrate communities. Towards understanding temporal and spatial variation of these organisms, we compiled the TREAM dataset (Time seRies of European freshwAter Macroinvertebrates), consisting of macroinvertebrate community time series from 1,816 river and stream sites (mean length of 19.2 years and 14.9 sampling years) of 22 European countries sampled between 1968 and 2020. In total, the data include >93 million sampled individuals of 2,648 taxa from 959 genera and 212 families. These data can be used to test questions ranging from identifying drivers of the population dynamics of specific taxa to assessing the success of legislative and management restoration efforts.

Abstract: Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss 1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity 2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European countries between 1968 and 2020, we quantified temporal trends in taxonomic and functional diversity and their responses to environmental pressures and gradients. We observed overall increases in taxon richness (0.73% per year), functional richness (2.4% per year) and abundance (1.17% per year). However, these increases primarily occurred before the 2010s, and have since plateaued. Freshwater communities downstream of dams, urban areas and cropland were less likely to experience recovery. Communities at sites with faster rates of warming had fewer gains in taxon richness, functional richness and abundance. Although biodiversity gains in the 1990s and 2000s probably reflect the effectiveness of water-quality improvements and restoration projects, the decelerating trajectory in the 2010s suggests that the current measures offer diminishing returns. Given new and persistent pressures on freshwater ecosystems, including emerging pollutants, climate change and the spread of invasive species, we call for additional mitigation to revive the recovery of freshwater biodiversity.

20. Clinical correlates of health preference and generic health-related quality of life in patients with colorectal neoplasms.

Author: Carlos K H Wong, Cindy L K Lam, Jensen T C Poon, and Dora L W Kwong
Subjects: Medicine, Science
Abstract: BACKGROUND: The aims of the study were to assess the health preference and health-related quality of life (HRQOL) in patients with colorectal neoplasms (CRN), and to determine the clinical correlates that significantly influence the HRQOL of patients. METHODS: Five hundred and fifty-four CRN patients, inclusive of colorectal polyp or cancer, who attended the colorectal specialist outpatient clinic at Queen Mary Hospital in Hong Kong between October 2009 and July 2010, were included. Patients were interviewed with questionnaires on socio-demographic characteristics, and generic and health preference measures of HRQOL using the SF-12 and SF-6D Health Surveys, respectively. Clinical information on stage of disease at diagnosis, time since diagnosis, primary tumour site was extracted from electronic case record. Mean HRQOL and health preference scores of CRN patients were compared with age-sex matched controls from the Chinese general population using independent t-test. Multiple linear regression analyses were conducted to explore the associations of clinical characteristics with HRQOL measures with the adjustment of socio-demographic characteristics. RESULTS: Cross-sectional data of 515 eligible patients responded to the whole questionnaires were included in outcome analysis. In comparison with age-sex matched normative values, CRN patients reported comparable physical-related HRQOL but better mental-related HRQOL. Amongst CRN patients, time since diagnosis was positively associated with health preference score whilst patients with rectal neoplasms had lower health preference and physical-related HRQOL scores than those with sigmoid neoplasms. Health preference and HRQOL scores were significantly lower in patients with stage IV colorectal cancer than those with other less severe stages, indicating that progressive decline from low-risk polyp to stage IV colorectal cancer was observed in HRQOL scores. CONCLUSION: In CRN patients, a more advanced stage of disease was associated with worse HRQOL scores. Despite potentially adverse effect of disease on physical-related HRQOL, the mental-related HRQOL of CRN patients were better than that of Chinese general population.

The aim of this study is to investigate microRNAs leading to liver metastasis. We applied microarray analysis and quantitative PCR to identify and validate dysregulated miRNAs in liver metastases when compared to primary CRCs. Functional significance and the underlying molecular mechanism of selected miRNA was demonstrated by a series of in vitro and in vivo assays. Our microarray analysis and subsequent quantitative PCR validation revealed that miR-885-5p was strongly up-regulated in liver metastases and in CRC cell-lines derived from distant metastases. Overexpression of miR-885-5p significantly induced cell migration, cell invasion, formation of stress fibre in vitro and development of liver and lung metastases in vivo . MiR-885-5p induced metastatic potential of CRC by repressing cytoplasmic polyadenylation element binding protein 2 transcription through directly binding to two binding sites on its 3′ untranslated region, and consequently led to up-regulation of TWIST1 and hence epithelial-mesenchymal transition. Our findings demonstrated the overexpression of miR-885-5p in liver metastasis and its roles in inducing CRC metastasis, potentiating development of miR-885-5p inhibitor to treat advanced CRC in the future.

Abstract: Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15–91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. We test whether (i) local long-term biodiversity trends are consistent among biogeoregions, realms and taxonomic groups, and (ii) changes in biodiversity correlate with regional climate and local conditions. Our results reveal that local trends of abundance, richness and diversity differ among biogeoregions, realms and taxonomic groups, demonstrating that biodiversity changes at local scale are often complex and cannot be easily generalized. However, we find increases in richness and abundance with increasing temperature and naturalness as well as a clear spatial pattern in changes in community composition (i.e. temporal taxonomic turnover) in most biogeoregions of Northern and Eastern Europe.

Abstract: Objective Our aim is to determine supportive care needs trajectories over the first year following colorectal cancer (CRC) surgery and identify factors differentiating these trajectories in a sample of Hong Kong Chinese CRC patients. Methods Overall, 247/274 Chinese patients diagnosed with CRC were recruited and assessed following admission for colorectal surgery, then at 1, 4, 8, and 12 months post-surgery. Supportive care needs were assessed at each assessment point. Latent growth mixture modeling identified trajectories within each of five assessed needs domains: health system and information (HSI), psychological (PSY), physical daily living (PDL), patient care and support (PCS), and sexuality (SEX) needs. Results Results indicated four needs trajectories each for HSI, PSY, and PDL domains, three for the PCS and two for the SEX domains. Most patients showed stable low levels of unmet PSY (86%), PDL (86%), PCS (81%), and SEX (98%) supportive care needs. One in seven patients showed persistent high, unmet HSI needs. The coexistence of two or more unmet need domains were found among patients in the high-decline needs group. HSI trajectories were predicted by education level and positive cancer-related rumination, PSY and PCS needs; PSY trajectories were predicted by stoma and HSI needs; PDL trajectories were predicted by physical symptom distress, stoma, PCS, and HSI needs; PCS trajectories were predicted by negative cancer-related rumination, depression, HSI, and PSY needs. Conclusions These Chinese CRC patients showed generally low stable supportive care needs, but a minority demonstrated high persistent unmet needs. Supportive care services should target those at risk of prolonged high unmet needs. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract: © 2015 Lui Ng et al.Colorectal cancer (CRC) is one of the most common and fatal malignancies worldwide. The poor prognosis of colorectal cancer patients is due to development of chemoresistance and cancer metastasis. Recently osteopontin (OPN) has been associated with stem-like properties in colorectal cancer. This study further examined the clinicopathological significance of OPN in CRC and its effect on chemoresistance and transcription of stem cell markers. We examined the transcription level of OPN in 84 CRC patients and correlated the expression with their clinicopathological parameters. The associations of OPN overexpression with transcription of stem cell markers and response to chemotherapy in DLD1-OPN overexpressing clones and CRC patients were also investigated. Our results showed that OPN was significantly overexpressed in CRC, and its overexpression correlated with tumor stage and poor prognosis. Overexpression of CRC induced OCT4 and SOX2 expression in vitro and correlated with SOX2 overexpression in CRC patients. In addition, DLD1-OPN overexpressing cells showed enhanced ability to survive upon oxaliplatin treatment, and OPN expression was higher in CRC patients who were resistant to oxaliplatin-involved chemotherapy treatment. Thus, CRC cells overexpressing OPN demonstrated stem-like properties and OPN inhibition is a potential therapeutic approach to combat CRC progression and chemoresistance., published_or_final_version

Abstract: Bmi1 is overexpressed in gastrointestinal cancers, including colorectal cancer (CRC); however, its role as a non-invasive biomarker in CRC has not been established. The aim of this study was to compare the plasma Bmi1 mRNA levels prior to and following curative resection of the primary tumor in CRC patients and to determine their association with the clinicopathological parameters. The plasma Bmi1 mRNA level was measured by quantitative polymerase chain reaction and expressed as cycle threshold value. There was no significant difference between the overall pre- and postoperative plasma Bmi1 mRNA level (31.73±2.63 vs. 31.93±2.88, respectively; P=0.614) in 45 CRC patients. However, when grouped into non-metastatic and metastatic CRC patients, the postoperative Bmi1 transcript level was found to be significantly lower compared to the preoperative level in patients with non-metastatic CRC (32.13±2.677 31.44±2.764, respectively; P=0.041), whereas there was a trend towards a higher postoperative Bmi1 transcript level compared to the preoperative level in the metastatic counterpart (30.85±3.916 vs. 33.27±0.718, respectively; P=0.164). Furthermore, when the patients were categorized into two groups according to their plasma Bmi1 postoperative vs. preoperative level status, we observed that patients without a reduction in the postoperative plasma Bmi1 mRNA levels exhibited a significantly higher rate of distant metastasis following primary resection (P=0.017) and a significantly worse prognosis regarding disease-free survival (P=0.016) when compared to the reduced postoperative plasma Bmi1 level counterparts. In conclusion, plasma Bmi1 mRNA levels may serve as a non-invasive biomarker for monitoring occult metastasis and predicting the development of distant metastasis.

The aim of this study was to study miR-139-3p and miR-622 in serum as a non-invasive biomarker for colorectal cancer diagnosis. We applied quantitative polymerase chain reaction to determine the levels of miR-139-3p and miR-622 in 42 pairs of tumor and adjacent non-tumor tissues, and in serum samples of 117 patients and 90 control subjects. Our results showed that miR-139-3p was silenced whereas miR-622 was overexpressed in colorectal cancer. Similarly, serum miR-139-3p level was significantly lower in colorectal cancer patients than in control subjects whereas miR-622 was more frequently detectable in patients. ROC analysis showed that AUC of miR-139-3p was 0.9935, with a sensitivity of 96.6% and specificity of 97.8%. Serum miR-139-3p level showed high sensitivity and specificity for both early and late stage CRCs and proximal and distal CRCs. Detectable serum miR-622 showed a sensitivity of 87.5% and specificity of 63.5% for discriminating CRC patients, but the sensitivity dropped for late stage patients (72.7%). We also included analyses of the blood CEA level for comparing the diagnostic performance of these blood-based biomarkers. The median level in CRC patients (3.6 ng/ml) was significantly higher than that in control (1.8 ng/ml). The AUC value of CEA in diagnosing CRC patients was 0.7515. CEA showed a positive correlation with tumor stage and age of patients and its level was higher in male. Collectively, serum miR-139-3p has strong potential as a promising non-invasive biomarker in colorectal cancer detection.

48. Geeopsis longicornis Olofsson 1917

Abstract: Geeopsis longicornis (Olofsson, 1917) References and records from Norway Tachidius longicornis n. sp. �� Olofsson (1917): 34 �� 35, type locality �� Svalbard archipelago, several record areas given (from fresh water �� Advent Bay, Esmark Glacier, Crednermorenen (moraine) and from brackish water �� at Green Harbour, Billen Bay). Tachidius longicornis Olofsson (1917) �� Olofsson (1918): 183 �� 646. Olofsson (1917) considered T. longicornis to be very close to G. incisipes (Klie, 1913) �� two species distinguished by their size and the morphology of the antenna. Later T. longicornis was considered to be a synonym of G. incisipes (Gurney 1932; Lang 1948). However, the species was reinstated as a valid species and placed in the genus Geeopsis by Huys (2009) as G. longicornis (Olofsson 1917) comb. nov. Olofsson (1918) found it from a brackish lagoon near Nordenskiold Glacier. The latter habitat consists of a shallow inner part with slowly running fresh water from the lowlands. Samples were taken from this part. In the lagoon �� s outer part, water mixes with the salty water of the fjord and the proprotion of salt and fresh water changes with the tides. Another sampling locality, Lake Reliktsee (today, Vallunden), located in Crednermorenen (moraine), is connected to the sea by a channel. The tide flows in and out through the channel and therefore the water is salty (Kristensen et al. 2008). Still, Olofsson (1918) clearly indicated that he found Tachidius species in pure fresh water and suggested that this is a relict species that probably had been passively spread from northern Europe to Svalbard in later post-glacial time., Published as part of Dimante-Deimantovica, I., Jensen, T.

Abstract: Maraenobiotus insignipes insignipes (Lilljeborg, 1902) References and records from Norway Canthocamptus insignipes sp. nov. �� Lilljeborg (1902): 53 �� 56, type locality �� Porsanger municipality, Finnmark County, Norway. Lilljeborg (1902) published his synopsis on the freshwater harpacticoid fauna of Sweden; however, the material he used for the description of M. insignipes insignipes was from Norway and the species has not been found in Sweden. The material was provided by the leading Swedish zoological curator, Gustaf Kolthoff, and it was sampled from a small water body located in the neighbourhood of Porsanger, Finmark county. Later, a more detailed description including drawings of this species was provided by Olofsson (1917), based on the original material of Lilljeborg (1902)., Published as part of Dimante-Deimantovica, I., Jensen, T.
