A comprehensive examination of the evidence for whole of diet patterns in Parkinson's disease: a scoping review.

Both motor and non-motor symptoms of Parkinson's disease (PD), a progressive neurological condition, have broad-ranging impacts on nutritional intake and dietary behaviour. Historically studies focused on individual dietary components, but evidence demonstrating ameliorative outcomes with whole-of-diet patterns such as Mediterranean and Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) is emerging. These diets provide plenty of antioxidant rich fruits, vegetables, nuts, wholegrains and healthy fats. Paradoxically, the ketogenic diet, high fat and very low carbohydrate, is also proving to be beneficial. Within the PD community, it is well advertised that nutritional intake is associated with disease progression and symptom severity but understandably, the messaging is inconsistent. With projected prevalence estimated to rise to 1.6 million by 2037, more data regarding the impact of whole-of-diet patterns is needed to develop diet-behaviour change programmes and provide clear advice for PD management. Objectives and Methods: Objectives of this scoping review of both peer-reviewed academic and grey literatures are to determine the current evidence-based consensus for best dietary practice in PD and to ascertain whether the grey literature aligns. Results and Discussion: The consensus from the academic literature was that a MeDi/MIND whole of diet pattern (fresh fruit, vegetables, wholegrains, omega-3 fish and olive oil) is the best practice for improving PD outcomes. Support for the KD is emerging, but further research is needed to determine long-term effects. Encouragingly, the grey literature mostly aligned but nutrition advice was rarely forefront. The importance of nutrition needs greater emphasis in the grey literature, with positive messaging on dietary approaches for management of day-to-day symptoms.

How a 7-Week Food Literacy Cooking Program Affects Cooking Confidence and Mental Health: Findings of a Quasi-Experimental Controlled Intervention Trial.

Obesity and mental health disorders are rising simultaneously with shifting dietary behavior away from home cooking, toward typically nutrition-poor and energy-dense convenience meals. Food literacy strongly influences nutrition choices. Community-based cooking interventions target barriers to healthy eating and facilitate development of food literacy skills, thereby potentially increasing preparation of home-cooked meals and positively influencing health. This study of 657 healthy Australian adults explored the efficacy of a 7-week cooking program in improving cooking confidence, whether this transferred to behavior surrounding food, and/or affected mental health. Significant post-program improvements in cooking confidence and satisfaction (all p < 0.001, η p 2 1.12 large), ability to change eating habits (p < 0.001) and overcome lifestyle barriers (p = 0.005) were observed for the intervention group but not control. Participation also improved mental and general health (all p < 0.05, η p 2 0.02 small). No changes were observed for acquisition and consumption of food, or nutrition knowledge in either group. This 7-week cooking program built cooking confidence and improved general and mental health but did not change dietary behavior. To further improve nutrition related behaviors associated with better mental health, more effort is needed to recruit those with below-average nutrition knowledge and interest in cooking.

Data supporting development and validation of liquid chromatography tandem mass spectrometry method for the quantitative determination of bile acids in feces.

Measuring bile acids in feces has an important role in disease prevention, diagnosis, treatment, and can be considered a measure of health status. Therefore, the primary aim was to develop a sensitive, robust, and high throughput liquid chromatography tandem mass spectrometry method with minimal sample preparation for quantitative determination of bile acids in human feces applicable to large cohorts. Due to the chemical diversity of bile acids, their wide concentration range in feces, and the complexity of feces itself, developing a sensitive and selective analytical method for bile acids is challenging. A simple extraction method using methanol suitable for subsequent quantification by liquid chromatography tandem mass spectrometry has been reported in, "Extraction and quantitative determination of bile acids in feces" [1]. The data highlight the importance of optimization of the extraction procedure and the stability of the bile acids in feces post-extraction and prior to analysis and after several freeze-thaw cycles.

Association between Fruit and Vegetable Intakes and Mental Health in the Australian Diabetes Obesity and Lifestyle Cohort.

Increasing prevalence of mental health disorders within the Australian population is a serious public health issue. Adequate intake of fruits and vegetables (FV), dietary fibre (DF) and resistant starch (RS) is associated with better mental and physical health. Few longitudinal studies exist exploring the temporal relationship. Using a validated food frequency questionnaire, we examined baseline FV intakes of 5845 Australian adults from the AusDiab study and estimated food group-derived DF and RS using data from the literature. Perceived mental health was assessed at baseline and 5 year follow up using SF-36 mental component summary scores (MCS). We conducted baseline cross-sectional analysis and prospective analysis of baseline dietary intake with perceived mental health at 5 years. Higher baseline FV and FV-derived DF and RS intakes were associated with better 5 year MCS (p < 0.001). A higher FV intake (754 g/d vs. 251 g/d, Q4 vs. Q1) at baseline had 41% lower odds (OR = 0.59: 95% CI 0.46-0.75) of MCS below population average (<47) at 5 year follow up. Findings were similar for FV-derived DF and RS. An inverse association was observed with discretionary food-derived DF and RS. This demonstrates the association between higher intakes of FV and FV-derived DF and RS with better 5 year mental health outcomes. Further RCTs are necessary to understand mechanisms that underlie this association including elucidation of causal effects.

Extraction and quantitative determination of bile acids in feces.

With rapid advances in gut microbiome research, fecal bile acids are increasingly being monitored as potential biomarkers of diet related disease susceptibility. As such, rapid, robust and reliable methods for their analysis are of increasing importance. Herein is described a simple extraction method for the analysis of bile acids in feces suitable for subsequent quantification by liquid chromatography and tandem mass spectrometry. A C18 column separated the analytes with excellent peak shape and retention time repeatability maintained across 800 injections. The intra-day and inter-day precision and accuracy was greater than 80%. Recoveries ranged from 83.58 to 122.41%. The limit of detection and limit of quantification were in the range 2.5-15 nM, respectively. The optimized method involved extracting bile acids from wet feces with minimal clean up. A second aliquot of fecal material was dried and weighed to correct for water content. Extracting from dried feces showed reduced recovery that could be corrected for by spiking the feces with deuterated standards prior to drying. Storage of the extracts and standards in a refrigerated autosampler prior to analysis on the LC-MS is necessary. Multiple freeze-thaws of both extracts and standards lead to poor recoveries for some bile acids. The method was successfully applied to 100 human fecal samples.

Risk to patients, risk to clinicians: a three-site audit of the documentation of counselling in first episode genital herpes.

National guidelines give advice on topics which should be covered when counselling patients with a new diagnosis of genital herpes (HSV) with the aim of reducing transmissions. This three-site UK audit of documentation of counselling for patients with a new diagnosis of genital herpes reviewed the records of 284 patients. Documentation in all areas of counselling was limited and this may result in adverse medico-legal consequences for patients and clinicians.

The study protocol for a pseudo-randomised pre-post designed controlled intervention trial to study the effects of a 7-week cooking program on self-efficacy and biomarkers of health: the ECU lifestyle and biomarkers get connected study (ECULABJMOF) including the Jamie's Ministry of Food WA participant experience.

BACKGROUND: Australia, like other nations, has experienced a shift in dietary patterns away from home cooking of nutritious foods, towards a reliance on pre-prepared convenience meals. These are typically energy-dense, nutrient-poor and contribute to the rising prevalence of obesity and chronic disease burden. The aims of this study were to evaluate whether a community-based cooking program instigated a change to participants' skills, attitudes, knowledge, enjoyment and satisfaction of cooking and cooking confidence (self-efficacy). METHODS: The pseudo-random, pre-post study design consisted of an intervention and a control group. Participant recruitment and group allocation was based on their program start dates. Intervention participants were surveyed three times (baseline, 7 weeks and 6 months) and the control group were surveyed at baseline and 5 weeks. All participants were registered via an online website and were 18 years or over. Upon consent, participants were offered four levels of commitment, defined by different assessments. The minimum participation level included an online survey and levels 2, 3 and 4 involved attendance at a clinic with increasing functional, anthropometric and biomarker measurements. Primary endpoints were participants' cooking confidence as a proxy for self-efficacy. Secondary endpoints were dietary intake, physical activity levels, body composition, anthropometry, blood, urine and faecal biomarkers of systemic, physical and mental health. DISCUSSION: The community cooking program provided participants with information and advice on food sourcing, preparation and nutrition to improve home cooking skills. The study was designed to explore whether food literacy programs are efficacious in improving participant physical health and well-being in order to combat the rise in obesity and diet-related disease. It will support future use of public health cooking program initiatives aimed at improving food literacy, self-efficacy and physical and mental health. The extensive data collected will inform future research into the relationship between diet, the gut-microbiota and human health.

Delayed postoperative diet is associated with a greater incidence of prolonged postoperative ileus and longer stay in hospital for patients undergoing gastrointestinal surgery.

AIM: Recent evidence favours a move away from delaying postoperative nutrition towards early feeding practices for better patient outcomes after gastrointestinal surgery. The aim of the present study was to investigate postoperative diet progression and patient outcomes in a secondary hospital with a view to inform future practice. METHODS: This was a retrospective study of gastrointestinal surgery patients (n = 69) at a Western Australian general hospital. Demographic data and outcomes were collected from patient records and included presence or absence of prolonged postoperative ileus, length of stay in hospital, days on minimal nutrition and days until first flatus or stool. RESULTS: A significant positive association was observed between number of days a patient remained on minimal nutrition and length of stay in the overall group (r = 0.66, P < 0.01). Patients who developed prolonged postoperative ileus (n = 18, 26%) had a greater number of days on minimal nutrition (20.0 vs 8.0 days, P < 0.01), longer stay in hospital (15.0 vs 8.0 days, P < 0.01) and increased number of days to first flatus or stool (4.0 vs 2.4 days, P < 0.01) compared with those who did not develop prolonged postoperative ileus (n = 51, 74%). CONCLUSIONS: This retrospective study of current practice in a secondary-care general hospital highlights the gap between traditional care and the improved outcomes reported in the literature when early feeding practices are adopted after GI surgery. Further investigation of barriers and enablers is necessary to provide insight into developing the most appropriate strategy to achieve this.

Implications of Untreated Cleft Palate in the Developing World: Adaptation of an Outcome Measure.

OBJECTIVES: To identify the implications of living with untreated cleft palate and develop an outcome measure which reflects the broad impact of surgery but is sensitive to the physical impact, speech changes, and psychosocial implications of late intervention. Design, Participants, Setting: Focus groups and individual interviews were used to gather information on the implications of living with untreated cleft palate and the impact of subsequent surgery. Participants included 11 individuals attending a cleft department in India whose cleft had persisted into adolescence or adulthood, as well as 16 of their family members. The findings were used to assess whether the Therapy Outcome Measure (TOM) could capture the implications of untreated cleft palate and the impact of surgery beyond that of speech alone. RESULTS: The findings indicated that the implications of living with untreated cleft palate revolved around difficulties with communication, reduced autonomy, and nasal regurgitation. These issues are encapsulated within the third and fourth domains of the TOM, but there is a need for an adapted version (TOM-clp) to use in the developing world, incorporating areas specific to cleft palate. CONCLUSION: The TOM has potential as a global tool for measuring the broad impact, including the psychosocial benefit, from attending to untreated cleft palate.

The Relationship Between Problem-Solving Ability and Self-Harm Amongst People with Mild Intellectual Disabilities.

BACKGROUND: The purpose of this study was to investigate the relationship between depression, hopelessness, problem-solving ability and self-harming behaviours amongst people with mild intellectual disabilities (IDs). METHODS: Thirty-six people with mild IDs (77.9% women, Mage  = 31.77, SD = 10.73, MIQ  = 62.65, SD = 5.74) who had a history of self-harm were recruited. Participants were asked to complete measures of depression, hopelessness and problem-solving ability. RESULTS: Cutting was most frequently observed, and depression was prevalent amongst the sample. There was a significant positive relationship between depression and hopelessness, while there was no significant relationship between self-harm and depression or hopelessness. Problem-solving ability explained 15% of the variance in self-harm scores. CONCLUSIONS: Problem-solving ability appears to be associated with self-harming behaviours in people with mild IDs.

An evaluation of the EQUIP treatment programme with men who have intellectual or other developmental disabilities.

BACKGROUND: The Equipping Youth to Help One Another Programme (EQUIP) was designed for young offenders to address a developmental delay in moral reasoning, distorted cognitions and social skills. METHODS: The present authors undertook a single case series study and piloted an adapted version of the EQUIP programme with three men with intellectual disabilities and four men with a diagnosis of Asperger Syndrome, all of whom were detained in a medium-secure forensic unit for people with intellectual disabilities. Treatment was delivered over a 12-week period, and participants took part in four-one-hour sessions per week. RESULTS: The results suggested that treatment was successful at increasing moral reasoning ability, reducing distorted cognitions and improving ability to choose effective solutions to problems. However, treatment did not have a significant effect upon anger. CONCLUSIONS: The EQUIP programme is a promising treatment, but further research is needed to investigate its effectiveness with men with intellectual or other developmental disabilities.
