Talking the walk : understanding active travel in Ordsall

Talking the Walk was undertaken between January and July 2017 and sought to understand the enablers and barriers towards active travel (specifically, walking and cycling) in the Ordsall area of Salford. A research approach was piloted which can be transferable to other areas. Methods included interviews, conversations, structured workshops and incorporated an ‘ethnographic’ element involving walking on routes around the area. The findings provided an understanding of community issues which extend beyond walking and cycling, but which are also influential on the likelihood of residents to consider active travel as a realistic trip option. The research highlighted that by adding more understanding of local societal issues, it is possible to appreciate the complexity of changing travel behaviour at a community level. The changing culture of the area, rapid regeneration and a perceived gentrification of some nearby areas were all discussed by community members in conjunction with conversations on day-to-day travel. Some shared feelings of being a closed off community may change as building developments are completed. More positively, the regular focus on discussing active travel through the time-period of the project led to a more positive outlook, with anecdotal evidence from discussions at the final workshop suggesting that residents had started to think more about changing their travel habits. The open and honest discussions on travel, repeated over time, combined with the production of the film were important immersive elements of the research project. The fact that practitioners, residents and academic researchers came together to guide the research at each stage was a particular strength in this regard. Understanding a community in its entirety can provide more tangible understanding of personal travel. The use of community hubs and locations was also beneficial as it built familiarity between researchers and the community. In research terms this project adds another level of understanding on engaging communities to travel actively which can be explored in future projects. In particular, this approach can be drawn from to use with communities in conjunction with new infrastructure and changes resulting from development. The next step will involve proposing larger-scale research, geographically and of longer duration

Can we continue research in splenectomized dogs? Mycoplasma haemocanis: Old problem - New insight

We report the appearance of a Mycoplasma haemocanis infection in laboratory dogs, which has been reported previously, yet, never before in Europe. Outbreak of the disease was triggered by a splenectomy intended to prepare the dogs for a hemorrhagic shock study. The clinical course of the dogs was dramatic including anorexia and hemolytic anemia. Treatment included allogeneic transfusion, prednisone, and oxytetracycline. Systematic follow-up (n=12, blood smears, antibody testing and specific polymerase chain reaction) gives clear evidence that persistent eradication of M. haemocanis is unlikely. We, therefore, had to abandon the intended shock study. In the absence of effective surveillance and screening for M. haemocanis, the question arises whether it is prudent to continue shock research in splenectomized dogs. Copyright (C) 2004 S.

Outcome of ATP-based tumor chemosensitivity assay directed chemotherapy in heavily pre-treated recurrent ovarian carcinoma

BACKGROUND: We wished to evaluate the clinical response following ATP-Tumor Chemosensitivity Assay (ATP-TCA) directed salvage chemotherapy in a series of UK patients with advanced ovarian cancer. The results are compared with that of a similar assay used in a different country in terms of evaluability and clinical endpoints. METHODS: From November 1998 to November 2001, 46 patients with pre-treated, advanced ovarian cancer were given a total of 56 courses of chemotherapy based on in-vitro ATP-TCA responses obtained from fresh tumor samples or ascites. Forty-four patients were evaluable for results. Of these, 18 patients had clinically platinum resistant disease (relapse < 6 months after first course of chemotherapy). There was evidence of cisplatin resistance in 31 patients from their first ATP-TCA. Response to treatment was assessed by radiology, clinical assessment and tumor marker level (CA 125). RESULTS: The overall response rate was 59% (33/56) per course of chemotherapy, including 12 complete responses, 21 partial responses, 6 with stable disease, and 15 with progressive disease. Two patients were not evaluable for response having received just one cycle of chemotherapy: if these were excluded the response rate is 61%. Fifteen patients are still alive. Median progression free survival (PFS) was 6.6 months per course of chemotherapy; median overall survival (OAS) for each patient following the start of TCA-directed therapy was 10.4 months (95% confidence interval 7.9-12.8 months). CONCLUSION: The results show similar response rates to previous studies using ATP-TCA directed therapy in recurrent ovarian cancer. The assay shows high evaluability and this study adds weight to the reproducibility of results from different centre

Confronting chemobrain: an in-depth look at survivors’ reports of impact on work, social networks, and health care response

Mild cognitive impairment following chemotherapy is one of the most commonly reported post treatment symptoms by breast cancer survivors. This deterioration in cognitive function, commonly referred to as “chemobrain” or “chemofog,” was largely unacknowledged by the medical community until recent years. Although chemobrain has now become the subject of more vigorous exploration, little is known about this specific phenomenon’s psychosocial impact on breast cancer survivors. This research documents in-depth the effects that cognitive impairment has on women’s personal and professional lives, and our data suggest that greater attention needs to be focused on this arena of survivorship. The results are based on an in-depth qualitative study of 74 white and African American breast cancer survivors in California who experience post-treatment side effects. The data reported herein were obtained through the use of focus groups and in-depth interviews. Our data indicate that cognitive impairment can be problematic for survivors, with many asserting that it is their most troublesome post treatment symptom. Survivors report diminished quality of life and daily functioning as a result of chemobrain. Respondents detail a range of coping strategies that they are forced to employ in order to manage their social and professional lives. Chemobrain significantly impairs a proportion of cancer survivors, at great cost to them economically, emotionally, and interpersonally. This suggests that more research needs to be conducted on the psychosocial ramifications of post treatment symptoms in order to inform the efforts of the medical and mental health communities as well as the support networks of survivors. A better and broader understanding of the effects of cognitive impairment both in the medical community and among lay people could pave the way for improved social and psychological services for this population

A mutation in the viral sensor 2'-5'-oligoadenylate synthetase 2 causes failure of lactation.

We identified a non-synonymous mutation in Oas2 (I405N), a sensor of viral double-stranded RNA, from an ENU-mutagenesis screen designed to discover new genes involved in mammary development. The mutation caused post-partum failure of lactation in healthy mice with otherwise normally developed mammary glands, characterized by greatly reduced milk protein synthesis coupled with epithelial cell death, inhibition of proliferation and a robust interferon response. Expression of mutant but not wild type Oas2 in cultured HC-11 or T47D mammary cells recapitulated the phenotypic and transcriptional effects observed in the mouse. The mutation activates the OAS2 pathway, demonstrated by a 34-fold increase in RNase L activity, and its effects were dependent on expression of RNase L and IRF7, proximal and distal pathway members. This is the first report of a viral recognition pathway regulating lactation

Brand Suicide? Memory and Liking of Negative Brand Names

Negative brand names are surprisingly common in the marketplace (e.g., Poison perfume; Hell pizza, and Monster energy drink), yet their effects on consumer behavior are currently unknown. Three studies investigated the effects of negative brand name valence on brand name memory and liking of a branded product. Study 1 demonstrates that relative to nonnegative brand names, negative brand names and their associated logos are better recognised. Studies 2 and 3 demonstrate that negative valence of a brand name tends to have a detrimental influence on product evaluation with evaluations worsening as negative valence increases. However, evaluation is also dependent on brand name arousal, with high arousal brand names resulting in more positive evaluations, such that moderately negative brand names are equally as attractive as some non-negative brand names. Study 3 shows evidence for affective habituation, whereby the effects of negative valence reduce with repeated exposures to some classes of negative brand name

Cerebral activations related to ballistic, stepwise interrupted and gradually modulated movements in parkinson patients

Patients with Parkinson's disease (PD) experience impaired initiation and inhibition of movements such as difficulty to start/stop walking. At single-joint level this is accompanied by reduced inhibition of antagonist muscle activity. While normal basal ganglia (BG) contributions to motor control include selecting appropriate muscles by inhibiting others, it is unclear how PD-related changes in BG function cause impaired movement initiation and inhibition at single-joint level. To further elucidate these changes we studied 4 right-hand movement tasks with fMRI, by dissociating activations related to abrupt movement initiation, inhibition and gradual movement modulation. Initiation and inhibition were inferred from ballistic and stepwise interrupted movement, respectively, while smooth wrist circumduction enabled the assessment of gradually modulated movement. Task-related activations were compared between PD patients (N = 12) and healthy subjects (N = 18). In healthy subjects, movement initiation was characterized by antero-ventral striatum, substantia nigra (SN) and premotor activations while inhibition was dominated by subthalamic nucleus (STN) and pallidal activations, in line with the known role of these areas in simple movement. Gradual movement mainly involved antero-dorsal putamen and pallidum. Compared to healthy subjects, patients showed reduced striatal/SN and increased pallidal activation for initiation, whereas for inhibition STN activation was reduced and striatal-thalamo-cortical activation increased. For gradual movement patients showed reduced pallidal and increased thalamo-cortical activation. We conclude that PD-related changes during movement initiation fit the (rather static) model of alterations in direct and indirect BG pathways. Reduced STN activation and regional cortical increased activation in PD during inhibition and gradual movement modulation are better explained by a dynamic model that also takes into account enhanced responsiveness to external stimuli in this disease and the effects of hyper-fluctuating cortical inputs to the striatum and STN in particular
