Do Soup Kitchen Meals Contribute to Suboptimal Nutrient Intake & Obesity in the Homeless Population?

The double burden of suboptimal nutrient intake and obesity exists when available foods lack essential nutrients to promote health and provide high amounts of energy. This study evaluated the nutrition content of 41 meals served to the homeless at 3 urban soup kitchens. The mean nutrient content of all meals and of meals from each of the kitchens was compared to two-thirds of the estimated average requirement (EAR). The mean nutrient content of the meals did not provide two-thirds of the EAR for energy, vitamin C, magnesium, zinc, dietary fiber, or calcium but provided 11.8% of calories from saturated fat. On average one meal did not meet homeless individuals’ estimated requirements; however, 2 meals did meet estimated requirements but provided inadequate fiber and high amounts of energy, saturated fat, and sodium. Soup kitchen meals may contribute to the high prevalence of obesity and chronic disease reported in the homeless, food insecure population

Studies on the ability of minor groove binders to induce supercoiling in DNA

AbstractThe effect of various non-intercalating minor groove binders on closed circular DNA in the presence of topoisomerase I has been studied by means of agarose gel electrophoresis. Analogues of the netropsin series (lexitropsins) and SN-6999 can effectively produce positive supercoils, as indicated by analysis of the topoisomers in the presence of chloroquine and the evaluated linking number changes. Analogues of the distamycin series are less effective, and bisquaternary ammonium heterocycles, as well as DAPI and pentamidine, were found to be ineffective ligands. The large differences observed in the ability of minor groove binders to induce positive supercoils are discussed

From substance to process: A meta-ethnographic review of how healthcare professionals and patients understand placebos and their effects in primary care.

Research suggests that a 'placebo' can improve conditions common in primary care including pain, depression and irritable bowel syndrome. However, disagreement persists over the definition and clinical relevance of placebo treatments. We conducted a meta-ethnographic, mixed-research systematic review to explore how healthcare professionals and patients understand placebos and their effects in primary care. We conducted systematic literature searches of five databases - augmented by reference chaining, key author searches and expert opinion - related to views on placebos, placebo effects and placebo use in primary care. From a total of 34 eligible quantitative, qualitative and mixed-methods articles reporting findings from 28 studies, 21 were related to healthcare professionals' views, 11 were related to patients' views and two were related to both groups. In the studies under review, healthcare professionals reported using placebos at markedly different frequencies. This was highly influenced by how placebos were defined in the studies. Both healthcare professionals and patients predominantly defined placebos as material substances such as 'inert' pills, despite this definition being inconsistent with current scientific thinking. However, healthcare professionals also, but less prevalently, defined placebos in a different way: as contextual processes. This better concurs with modern placebo definitions, which focus on context, ritual, meaning and enactivism. However, given the enduring ubiquity of substance definitions, for both healthcare professionals and patients, we question the practical, clinical validity of stretching the term 'placebo' towards its modern iteration. To produce 'placebo effects', therefore, primary healthcare professionals may be better off abandoning placebo terminology altogether

Mulberry extract to modULate Blood glucosE Responses in noRmoglYcaemic adults (MULBERRY): study protocol for a randomized controlled trial

Background: worldwide sugar consumption has tripled during the last fifty years. High sugar intake is associated with weight gain and increased incidence of diabetes and has been linked with increased cardiovascular mortality. Reducing the health impact of dietary sugar and poor quality carbohydrate intake is a public health priority. IminoNorm®, a proprietary mulberry leaf extract (ME), may reduce blood glucose responses following dietary sugar and carbohydrate intake by reducing absorption of glucose from the gut. Previous research has shown that ME can reduce blood glucose and improve insulin responses in healthy subjects and also in subjects with raised fasting blood glucose levels. Mulberry leaf has an excellent safety profile. This pilot study will test a novel, safe, water soluble product in normoglycaemic adults in the UK to determine if it can reduce glucose absorption without increasing plasma insulin concentration.Methods/design: the trial will be a double-blind, individually randomised, four-arm single-dose crossover design to test the effect of three doses of ME in order to determine efficacy, dose response relationship and gastrointestinal side effects with respect to placebo. A total of 40 subjects will participate in this study and attend for four visits receiving each of the four interventions in random order.Discussion: we aim to test the evidence that mulberry leaf extract can reduce blood glucose without a disproportionate increase in blood insulin responses in healthy individuals in a high-quality research study based in the UK. It is hoped that this will lead to further randomised controlled trials and an effective dietary supplement to lower blood glucose concentration

Perceptions and practice of personal protective behaviors to prevent COVID-19 transmission in the G7 nations

Introduction: To combat the transmission of COVID-19, countries have endorsed a series of non-pharmaceutical measures. We evaluated the practice and perceptions of personal protective measures and social distancing across the G7 countries. Methods: Data were collected during 19–21 March 2020, from 7005 of Kantar’s online panelists aged >16 years across the G7 countries: Canada, France, Great Britain, Germany, Italy, Japan, and the United States. Data were post-stratified and weighted to match population distributions of the respective countries. Descriptive and multivariable analyses were conducted in late March 2020. Results: Males (vs females) and those less educated (vs college graduates) were less likely to practice personal protective measures and social distancing. Younger adults were also less likely to practice social distancing (vs adults >65 years old). Respondents who expressed concern about the impact of COVID-19 on their health, income or education had higher odds of practicing personal protective measures (AOR=2.81, 1.74, and 1.54, respectively) and social distancing (AOR=3.18, 1.68, and 1.89, respectively) compared to those who did not. Those who perceived precautionary measures as highly effective were also more likely to practice personal protective measures (AOR=2.05) and social distancing (AOR=3.99) compared to those who perceived them as ineffective. Conclusions: Concerns about COVID-19 and perceived effectiveness of precautionary measures strongly predict practice of protective measures, regardless of the types of behaviors. Population-wide interventions should focus on ensuring increased adherence and tailoring communications to groups that are less likely to practice protective behaviors

Systematic review of clinical practice guidelines for acne vulgaris published between January 2017 and July 2021

Background: Acne is very common, can cause considerable negative impact on quality of life and there is increasing concern over the use of long courses of oral antibiotics for this condition. Objectives: (1) To critically appraise reporting in acne guidelines and compare this with previous systematic review of acne guidelines. (2) Examine acne treatment guidance on pre-specified acne treatments of interest and compare between acne guidelines. Methods: Searches for new or updated guidelines were carried out in MEDLINE, Embase, Google Scholar, LILACS from 1 January 2017 to 31 July 2021, supplemented by searching a guideline-specific depository and checking for updates to guidelines included in previous review. We included guidelines, consensus statements or care protocols on the medical treatment of acne vulgaris in adults and/or children and excluded those that focused on a single intervention or subgroup of acne, regional adaptations of guidelines or guidelines included in previous review. AGREE II checklist was applied to critically appraise reporting of guidelines. Results were synthesised narratively. Results: Of 807 abstracts identified nine guidelines were identified that were eligible for inclusion. All guidelines had AGREE II scores above average in at least one domain and reporting was substantially improved compared to the systematic review of acne carried out 5 years previously. There was consensus between guidelines on the key role of topical treatments as first-line acne treatment and most recommended continuing topical treatments as maintenance therapy. There was considerable variation between guidelines on classification of severity, indications for commencing oral antibiotics and on maximum duration of oral antibiotics. However, there was consensus on the need for co-prescription of a non-antibiotic topical treatment when using oral antibiotics. There were notable differences on recommendations regarding provision of information for patients on how to use topical treatments or how to mitigate against side effects. Conclusions: Substantial differences in classification of acne severity hampered comparisons between guidelines. Although development and reporting of guidelines has improved over the past 5 years, differences in key recommendations remain, possibly reflecting uncertainties in the underlying evidence base. Differences between guidelines could have substantial implications for prevalence of antibiotic prescribing for acne

Mulberry-extract improves glucose tolerance and decreases insulin concentrations in normoglycaemic adults: results of a randomised double-blind placebo-controlled study

Background High sugar and refined carbohydrate intake is associated with weight gain, increased incidence of diabetes and is linked with increased cardiovascular mortality. Reducing the health impact of poor quality carbohydrate intake is a public health priority. Reducose, a proprietary mulberry leaf extract (ME), may reduce blood glucose responses following dietary carbohydrate intake by reducing absorption of glucose from the gut. Methods A double-blind, randomised, repeat measure, phase 2 crossover design was used to study the glycaemic and insulinaemic response to one reference product and three test products at the Functional Food Centre, Oxford Brooks University, UK. Participants; 37 adults aged 19–59 years with a BMI ≥ 20kg/m2 and ≤ 30kg/m2. The objective was to determine the effect of three doses of mulberry-extract (Reducose) versus placebo on blood glucose and insulin responses when co-administered with 50g maltodextrin in normoglycaemic healthy adults. We also report the gastrointestinal tolerability of the mulberry extract. Results Thirty-seven participants completed the study: The difference in the positive Incremental Area Under the Curve (pIAUC) (glucose (mmol / L x h)) for half, normal and double dose ME compared with placebo was -6.1% (-18.2%, 5.9%; p = 0.316), -14.0% (-26.0%, -2.0%; p = 0.022) and -22.0% (-33.9%, -10.0%; p<0.001) respectively. The difference in the pIAUC (insulin (mIU / L x h)) for half, normal and double dose ME compared with placebo was -9.7% (-25.8%, 6.3%; p = 0.234), -23.8% (-39.9%, -7.8%; p = 0.004) and -24.7% (-40.8%, -8.6%; p = 0.003) respectively. There were no statistically significant differences between any of the 4 groups in the odds of experiencing one or more gastrointestinal symptoms (nausea, abdominal cramping, distension or flatulence). Conclusions Mulberry leaf extract significantly reduces total blood glucose rise after ingestion of maltodextrin over 120 minutes. The pattern of effect demonstrates a classical dose response curve with significant effects over placebo. Importantly, total insulin rises were also significantly suppressed over the same time-period. There were no statistically significant differences between any of the treatment groups (including placebo) in the odds of experiencing one or more gastrointestinal symptoms. Mulberry extract may have multiple modes of action and further studies are necessary to evaluate ME as a potential target for the prevention of type 2 diabetes and the regulation of dysglycaemia
