A Prospective Randomized Controlled Trial to Study the Impact of a Nutrition-Sensitive Intervention on Adult Women With Cancer Cachexia Undergoing Palliative Care in India

Purpose. Advanced cancer patients with disease progression develop cachexia. Nevertheless, cancer patients at nutritional risk have shown improved body weight and quality of life with oral nutritional supplements. Method. This was a randomized controlled trial in adult female cancer patients (n = 63) attending palliative clinics, with symptoms of cachexia. Eligible patients were randomly distributed into control (n = 33) and intervention (n = 30) groups. Both groups were provided with nutritional and physical activity counseling, but the intervention group received an additional 100 g of Improved Atta (IAtta) for 6 months daily consumption. This study was designed to assess the efficacy of IAtta (with counseling) in enhancing the health status of cachexic patients. Anthropometric measurements, dietary intake, physical activity level and quality of life parameters were assessed at baseline, after 3 months, and at the end of 6 months. Results. Patients in the control group (n = 15) had significantly decreased body weight (P = .003), mid–upper-arm circumference (P = .002), and body fat (P = .002) by the end of intervention. A trend of body weight gain in the intervention group (n = 17; P = .08) and significant increase of body fat (P = .002) was observed; moreover, patients reported a significant improvement in fatigue (P = .002) and appetite scores (P = .006) under quality-of-life domains at the end of intervention. Conclusions. Embedding a nutrition-sensitive intervention ( IAtta ) within Indian palliative care therapy may improve quality of life and stabilize body weight in cancer cachexia patients.

Electrospun pH-sensitive core–shell polymer nanocomposites fabricated using a tri-axial process

A modified tri-axial electrospinning process was developed for the generation of a new type of pH-sensitive polymer/lipid nanocomposite. The systems produced are able to promote both dissolution and permeation of a model poorly water-soluble drug. First, we show that it is possible to run a tri-axial process with only one of the three fluids being electrospinnable. Using an electrospinnable middle fluid of Eudragit S100 (ES100) with pure ethanol as the outer solvent and an unspinnable lecithin-diclofenac sodium (PL–DS) core solution, nanofibers with linear morphology and clear core/shell structures can be fabricated continuously and smoothly. X-ray diffraction proved that these nanofibers are structural nanocomposites with the drug present in an amorphous state. In vitro dissolution tests demonstrated that the formulations could preclude release in acidic conditions, and that the drug was released from the fibers in two successive steps at neutral pH. The first step is the dissolution of the shell ES100 and the conversion of the core PL–DS into sub-micron sized particles. This frees some DS into solution, and later the remaining DS is gradually released from the PL–DS particles through diffusion. Ex vivo permeation results showed that the composite nanofibers give a more than twofold uplift in the amount of DS passing through the colonic membrane as compared to pure DS; 74% of the transmitted drug was in the form of PL–DS particles. The new tri-axial electrospinning process developed in this work provides a platform to fabricate structural nanomaterials, and the core–shell polymer-PL nanocomposites we have produced have significant potential applications for oral colon-targeted drug delivery.

How women use and experience western herbal practice for distress: implications for health care and self-management approaches.

Introduction: In the UK, common mental health disorders account for one in five of all work days lost, and cost employers £25bn each year. Herbal medicine has been shown to potentially be of use for mental distress, including conditions like anxiety. In 2008, 35% of British adults surveyed claimed to have used herbal medicine at some stage, the majority of whom were women. However, there is little research into how the users of western herbal medicine (WHM) experience the practice of herbal medicine, or how these experiences may change over time. Our research is studying women in the south-east of the UK who are suffering from distress (either as a primary complaint, or associated with another condition) who are seeking the services of a herbalist who practices WHM. Aim: To investigate the experiences of western herbal practice by women who are suffering with distress. Methods: The study is using semi-structured interviews of around thirty women, to elicit patient narratives at two time points. Thematic analysis is being used to consider how distressed women perceive and experience their distress, their reasons for using WHM, what contribution the women perceive the consultation and treatment with WHM may or may not make to their wellbeing, and whether their experiences change over time. Currently, sixteen women have been interviewed, and a preliminary thematic analysis has commenced. Results: Preliminary finding suggest that not only do women internalise their distress, but that they are surprisingly isolated in how they deal with it, whilst some also express social embarrassment about their experiences. The women perceived that their distress is not always considered seriously from their medical practitioners’ point of view. These women are drawn to herbalists not only in a search for effective treatment, but also to be given time to have their story heard, to form a collaborative relationship, and to attempt to regain some control of their life. The herbal treatment is valued due to its perceived naturalness, and reduced risk of adverse side effects. Nevertheless, WHM is just one of a number of self-care strategies that women utilise to help manage their distress. Discussion: Effective treatment is not only dependent upon the herbs, but also upon an effective therapeutic relationship. Feeling that the herbalist hears their story, provides a treatment plan that is individually tailored to the patient, and is available (even outside of the consultation) are all important in helping to establish this relationship.
