A growing body of evidence suggests that higher levels of physical activity are inversely associated with treatment side-effects and mortality in cancer survivors. Conversely, a limited percentage of cancer patients achieve physical activity goals and fitness compared with age-matched peers or other chronic medical conditions. In the last years, the next generation of activity trackers has integrated several parameters of physical fitness and mobility measurements. These multi-task devices go beyond objective physical activity measurements. Due to its functioning based on integrated platforms, clinicians may experience a unique opportunity to incorporate more active behaviors into their patients’ lives. This mini-review will discuss the advantages, challenges and future directions of most recent activity trackers in oncology.
Weight loss among patients with Head and Neck Cancer at St Vincent's Hospital...Cancer Institute NSW
Patients with Squamous cell carcinoma (SCC) of the Head and Neck (H&N) are often treated with curative intent using treatment protocols placing them at high risk of nutritional decline. Recently released COSA guidelines recommend that prophylactic enteral feeding should be considered for T4 upper aerodigestive tract tumours undergoing concurrent chemoradiotherapy. Evidence is yet to identify optimal method of nutrition intervention and timing across all tumour stages in this population.

Pathways to smoking care for cancer patients (P-SCIP): Stage 1Cancer Institute NSW
As survival from cancer has improved over time, the potential impact of cigarette smoking on cancer patients and survivors is of increasing relevance. In addition to increased risk of chronic disease such as cardiovascular and respiratory disease, continued smoking after a cancer diagnosis increases the risk of second primary cancer, cancer recurrence and is a cause of treatment complications. As well the profound adverse impact of continued smoking on health outcomes in cancer patients, continued smoking among people with cancer incurs significant cost to the health system.
One in five women who survive breast cancer will develop lymphoedema of the upper body at some point in their life. Following breast surgery, women are recommended to follow strategies to minimise their lymphoedema risk (e.g., limiting exposure of the at-risk arm to trauma). Adherence to these strategies is typically less than optimal.

World Cancer Congress, Saturday 6 December 2014
Short intro epigenetics & nutrigenomics& the early impact of nutrition Norwich Research Park
Our “genes” are not fixed: “Plasticity” of the genotype by epigenetic mechanisms => important for the phenotypic impact of nutrition.
• Histone and DNA modifications have impact on gene transcription efficiency. Methylation (more stable) and acetylation (more flexible) have impact on chromatin
structures.
• Epigenetic modifications have impact on offspring, embryo development, ageing and disease development or prevention => example: Dutch Hunger Winter.
Health status of future parents are very important for the future health of children.
Early healthy nutrition & lifestyle essential for successful healthy life & “ageing”.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

3. Aim
To develop and publish methodology for
carrying out rigorous systematic reviews of
mechanistic studies.
4. Why is this important?
Wealth of data on potential mechanisms
often not taken into account.
Methods for combining information from
human, animal and cell studies are lacking.
Need to identify gaps in the research.
5. Milestones
Develop a method for searching for relevant
mechanisms
Develop a method for systematically reviewing
specific mechanisms
Test the methodology above using a case study
6. Analytical approach
Large multi-disciplinary group
5 workshops -mixture of presentations with
discussion, small group exercises, round
table discussions
On going searches, and development of
methods, feedback to members of the team
Regular meetings between PIs and research
associates
8. Searching for studies
Incorporate an exhaustive list of mechanistic targets
(intermediate phenotypes-eg hallmarks of cancer,
hormones etc)
Three sets of searches:
Exposure-Outcome (E → O)
Exposure-Intermediate phenotype (E → IP)
Intermediate phenotype and Outcome (IP →O)
10. Introducing TeMMPo: Text Mining for Mechanism
Prioritisation -Tom Gaunt
Identifies co-occurrence of MESH headings in
scientific publications to indicate papers that link
an intermediate mechanism to either an exposure
or an outcome.
https://www.temmpo.org.uk/
14. Step 9: Synthesis of supporting evidence from in vitro and
xenograft models underpinning biological plausibility
Step 8: Integrate human and animal studies to develop an
evidence based conclusion
Step 7: Assess strength of overall body of evidence for human and
animal studies separately
Step 6: Synthesis of data from individual studies
Step 5: Assess the quality of individual studies
Step 4: Extract data
Step 3: Apply inclusion/exclusion criteria, including an
assessment of relevance
Step 2: Search for studies
Step 1: Specify research objectives
15. Cell line and animal
studies where a tumour
is transplanted into the
animal model
Supportive evidence from
in vitro and xenograft
models underpinning
biological plausibility
Question 1 - Has the
cancer arisen in the
animal model rather
than being
transplanted into
the animal?.
16. Wider potential impact
Apply this to WCRF systematic review of diet,
physical activity and cancer
Apply this to other systematic reviews of cancer
Apply this to research on other diseases
17. Strengths
Allows identification of potential mechanisms
Quantity and quality of data on specific
mechanisms can be assessed
Data from human and animal studies can be
assessed together
Will help to identify gaps in the research
19. Current gaps / priorities
Ability to identify pathways rather than single
intermediates
Ability to identify mechanisms using completely
hypothesis free approaches
Further automation to speed up process (eg
using text mining for RoB)
20. Future research
Incorporate changes recommended by validation
studies
