An integrative approach to cancer management combines conventional medicine with evidence-based complementary medicines/therapies and lifestyle interventions, for the treatment and prevention of disease and the optimisation of health. Its basis is a holistic one; to treat the whole person, not just the disease. It makes use of adjunct technologies which may assist the clinician in diagnosis of early carcinogenesis and monitoring of treatment effectiveness. Many factors contribute to the development of cancer including some which are largely modifiable by the patient and which oncologists may be in a position to advise on, such as stress, poor nutrition, lack of physical activity, poor sleep, and Vitamin D deficiency. An integrative approach to addressing these factors may contribute to better overall health of the patient and better outcomes. Evidence-based complementary medicine approaches...

Hay fever manifests as runny/blocked nose and often itchy/sore/swollen eyes, with symptoms greatly impacting the quality of life. Rescue medications such as antihistamines are often needed to restore function, but they may trigger some other unwanted side effects. Probiotics have shown promise to reduce hay fever symptoms.ObjectiveIn this randomized double-blind placebo-controlled 12-week trial, we aimed to assess the tolerability and efficacy of the probiotic formula “NC-Seasonal-Biotic” on symptoms, quality-of-life, and immunological and microbial factors.MethodsAdults, who had previously suffered from hay fever symptoms, were screened for eligibility and randomly allocated to probiotic or placebo trial powder. Treatment effectiveness was assessed by questionnaires, daily total-nasal-symptom-score, and weekly rhinoconjunctivitis quality-of-life questionnaire. Secondary o...

The purpose of this meta-analysis was to determine the effects of surgery on leukocyte vitamin C concentrations by assessing the amount and longevity of post-operative leukocyte vitamin C change. Data Sources We searched the PUBMED, SCOPUS, SciSearch and the Cochrane Library databases for relevant research papers. Studies were included until January 2022, with no time limits. Studies that reported means and standard deviations of leukocyte/buffer layer vitamin C concentrations before and after surgery were included into the meta-analysis. The meta-analysis comprised of eight studies. Results Seven studies (which included 8 individual studies) were included into our meta-analysis. Combined data from the meta-analysis displayed a significant depletion in mean leukocyte vitamin C concentrations during the first 24 hours following th...

Design: Mailed cross-sectional survey design. Setting and participants: 15 medical schools with students in 2005. Main Outcome Measure(s): Description of the amount and type of teaching in CAM. Results: Responses were received from all 15 universities. All but two had some form of teaching about CAM, generally incorporated into curricula. Integrated curricula made it impossible to quantify how much time was devoted to CAM teaching, but in general this over the entire course. CAM teaching was generally focused on broad concepts about CAM, critical appraisal skills and social aspects of medical practice. Conclusions: Current medical curricula do not appear to be addressing previously identified needs to train medical students to deal with patient enquiries or concerns about CAM use. Al...

Vitamin C is a molecule that has recently demonstrated both a potential link with cognitive function and a significant post-operative decline. Here, we present a case study of a 72-year-old male who underwent total knee replacement surgery. The patient demonstrated a substantial decline in plasma vitamin C concentrations, indicative of a severe deficiency, during the first post-operative week (post-operative Days 3 and 7). Similarly, at these time points, a number of validated paper and pen tests revealed a substantial decline in cognition on tasks relating to total recall, delayed recall, motor speed, recognition and motor speed, with no signs of delirium. These results provide the justification for larger, cohort studies to determine whether post-operative plasma vitamin C depletions could contribute to cognitive deficits post-operatively.

Biologically, vitamin C has exhibited roles in neuromodulation, neurodevelopment, vascular support, and neuroprotection. Vitamin C's contribution to cognitive function in both cognitively intact and impaired cohorts has previously been assessed, with little focus on gender variability. Objective The present study explored the interaction between gender and plasma vitamin C on cognitive performance, and the effect of different amounts of plasma vitamin C (adequate/inadequate) on various cognitive tasks by gender. Methods This retrospective analysis was conducted in healthy adults (n = 80, female = 52, male = 28, 24–96 y) with a range of blood plasma vitamin C concentrations. Cognitive assessments included the Swinburne University Computerized Cognitive Assessment Battery (SUCCAB) and 2 pen-and-paper tests, the Symbol Digits Modalities Test (SDMT) and the Hopkins Verbal ...

This is of particular concern in oncology patients as nausea and vomiting may result in malnutrition, decreased quality of life and in extreme cases, treatment stoppage. Therefore, the primary aim of this paper was to inform clinicians on the current literature regarding CINV including its effect on the patient, its pathophysiology, and current treatment options. In addition, this review will also discuss the usage of dietetic interventions as well as less utilised, novel interventions such as oral ginger extracts in the treatment of CINV. In order to address these issues, a systematic literature search was conducted using Pubmed, CINAHL, MEDLINE, Embase, and Health Source (Nursing/Academic Edition). A key finding of this review was that common dietary strategies (e.g. eating slowly, avoiding fatty foods) seem to be solely based on professional opinion as no clinical trials investigating these strategies were identified. In contrast, ginger extracts were found to possess several viable mechanisms that interact with CINV progression including 5-HT3, Substance P and acetylcholine receptor antagonism; anti-inflammatory and antioxidant properties; and gastrointestinal motility and gastric emptying modulation. In conclusion, research investigating dietetic interventions in the management of CINV is sparse and requires further investigation while novel intervention such as ginger, possess multiple mechanisms that may benefit CINV management. This review will discuss the prevalence and significance of CINV, dietetic and novel treatment options, and provide implications for clinical practise and future research.
