Land use, associated eel production, and abundance of fish and crayfish in streams in Waikato, New Zealand
The density and biomass of fish and crayfish, and the production of eels, was compared among streams in native forest, exotic forest, and pasture. Populations were estimated by multiple-pass electroshocking at 11 sites in hill-country streams in the Waikato region, North Island. Three sites were in native forest, four in exotic forest, and four in pasture. Length of stream sampled at each site was 46-94 m (41-246 m2 in area), and catchment areas up stream of the sites ranged from 0.44 to 2.01 km2.
A total of 487 fish were caught. The species were longfinned and shortfinned eels, banded kokopu, Cran's and redfinned bullies, and common smelt. Eels were the most abundant fish in all three land-use types, and shortfinned eels were more abundant at pastoral sites (mean density 1.11 fish m-2) than longfinned eels (mean density 0.129 fish m-2). Banded kokopu were present only at forested sites. Mean fish densities were greater at pastoral sites (1.55 fish m-2) than under either native forest (0.130 fish m-2) or exotic forest (0.229 fish m-2). Mean fish biomass was also greater at pastoral sites (89.7 g m-2) than under native forest (12.8 g m-2) or exotic forest (19.3 g m-2). Longfinned eels made a greater contribution to the fish biomass at all sites than did shortfinned eels. Densities of crayfish were high (0.46-5.40 crayfish m-2), but were not significantly different between land-use types. Crayfish biomass ranged from 1.79 to 11.2 g m-2. Total eel production was greater at pastoral sites (mean 17.9 g m-2 year-1) than at forest sites (mean 2.39 g m-2 year-1)

Node-Negative Non-small Cell Lung Cancer: Pathological Staging and Survival in 1765 Consecutive Cases
IntroductionThis study aimed to evaluate prognostic factors in patients with node-negative non-small cell lung cancer and to assess revised International Association for the Study of Lung Cancer staging recommendations for this group.MethodsA retrospective analysis of 1765 consecutive pathologically node-negative patients treated by surgical resection between 1984 and 2007 was performed. Survival analysis was conducted using the Kaplan-Meier method. The independence of prognostic factors was analyzed using multivariate Cox proportional hazards modeling.ResultsThe median age of patients was 68 years, and the average length of follow-up was 6.3 years. Perioperative mortality was 1.7%. The median survival was 6.5 years, with a 56% of the cohort surviving 5 years. Factors associated with poorer prognosis were male gender (hazard ratio [HR]: 1.30, p = <0.001), age (HR: 1.04 per year of increase, p < 0.001), limited resection (HR: 1.30, p = 0.002) tumor size (HR: 1.10 per 10 mm increase, p < 0.001), large cell histopathological cell type (HR: 1.35, p < 0.001), and positive resection margins (HR: 1.58, p = 0.002). T stage was a superior predictor of survival than tumor size (p < 0.001). There was no difference in survival by T-stage descriptor within stage T2 or T3.ConclusionsIn surgically treated, node-negative non-small cell lung cancer, revised International Association for the Study of Lung Cancer staging criteria stratify survival well. Age, gender, and extent of resection are also important predictors of survival. Current T-stage descriptor groupings are appropriate
ââŚ<i>It might not have occurred to my husband that this woman, his wife who is taking care of him has some emotional needs as wellâŚ</i>â: The Unheard Voices of Partners of Black African and Black Caribbean Men with Prostate Cancer
Š 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Purpose: Evidence suggests that partners of men with prostate cancer (CaP) experience greater psychosocial distress compared with men themselves. However, the experiences of partners of high-risk (1 in 4) Black African (BA) and Black Caribbean (BC) men with CaP remain poorly understood as existing research has predominantly focused on Caucasian populations. This study aimed to address this gap by exploring partnersâ experience and support needs as influenced both by the specific impacts of CaP, treatment side effects and socio-cultural context. Methods: Using a constructivist grounded theory approach, eight face-to-face, two Skype and one telephone interviews were conducted with eligible partners (n = 11). The interviews were analysed using constant comparison following key stages of open, focused and theoretical coding. Results: Three broad categories emerged which described participantsâ experiences: âpartner in the passenger seatâ, âcare-giving on an isolating journeyâ, and âcoping as a partnerâ. Findings showed that BA and BC cultural marital context influenced how partners experienced and traversed the CaP journey. Peripheral involvement in decision-making, communication restrictions, limited access to support and lack of recognition for their experiences and needs further contributed to partnersâ psychological and emotional distress. Conclusions: Cultural beliefs, behaviours and values should be taken into account when developing psychosocial support for partners and their men with CaP. Specifically providing information focused on partners and including them in the CaP care pathway could help ensure that partnersâ needs are recognised and improve marital communications. This could potentially help partners and their men to identify acceptable ways of supporting each other throughout the CaP experience
