"Obesity" and "Clinical Obesity" Men's understandings of obesity and its relation to the risk of diabetes: A qualitative study

<p>Abstract</p> <p>Background</p> <p>The 2007 Wanless report highlights the ever increasing problem of obesity and the consequent health problems. Obesity is a significant cause of diabetes. An increasing evidence base suggests that in terms of reducing diabetes and CVD risk, it is better to be "fit and fat" than unfit and of normal weight. There has been very little previous research into the understandings that men in the general population hold about the issues of weight, exercise and health; we therefore undertook this study in order to inform the process of health promotion and diabetes prevention in this group.</p> <p>Methods</p> <p>A qualitative study in North East England General Practice using a purposive sample of men aged 25 and 45 years (selection process designed to include 'normal', 'overweight' and 'obese' men). One to one audio-recorded semi structured interviews focused on: overweight and obesity, diet, physical activity and diabetes. Transcripts were initially analysed using framework analysis. Emerging themes interlinked.</p> <p>Results</p> <p>The men in this study (n = 17) understand the word obesity differently from the clinical definition; "obesity" was used as a description of those with fat in a central distribution, and understandings of the term commonly take into account fitness as well as weight. Men in their late 30s and early 40s described becoming more aware of health issues. Knowledge of what constitutes a 'healthy lifestyle' was generally good, but men described difficulty acting upon this knowledge for various reasons e.g. increasing responsibilities at home and at work. Knowledge of diabetes and the link between obesity and diabetes was poor.</p> <p>Conclusion</p> <p>Men in this study had a complex understanding of the interlinked importance of weight and fitness in relation to health. Obesity is understood as a description of people with centrally distributed fat, in association with low fitness levels. There is a need to increase understanding of the causes and consequences of diabetes. Discussion of increased health awareness by men round the age of 40 may indicate a window of opportunity to intervene at this time.</p

Inherently Chiral Calixarenes: Synthesis, Optical Resolution, Chiral Recognition and Asymmetric Catalysis

Inherently chiral calixarenes, whose chirality is based on the absence of a planar symmetry or an inversion center in the molecules as a whole through the asymmetric array of several achiral groups upon the three-dimensional calix-skeletons, are challenging and attractive chiral molecules, because of their potential in supramolecular chemistry. The synthesis and optical resolution of all varieties of inherently chiral calixarenes are systematically discussed and classified, and their applications in chiral recognition and asymmetric catalysis are thoroughly illustrated in this review

Anti-Phytopathogenic Activities of Macro-Algae Extracts

Aqueous and ethanolic extracts obtained from nine Chilean marine macro-algae collected at different seasons were examined in vitro and in vivo for properties that reduce the growth of plant pathogens or decrease the injury severity of plant foliar tissues following pathogen infection. Particular crude aqueous or organic extracts showed effects on the growth of pathogenic bacteria whereas others displayed important effects against pathogenic fungi or viruses, either by inhibiting fungal mycelia growth or by reducing the disease symptoms in leaves caused by pathogen challenge. Organic extracts obtained from the brown-alga Lessonia trabeculata inhibited bacterial growth and reduced both the number and size of the necrotic lesion in tomato leaves following infection with Botrytis cinerea. Aqueous and ethanolic extracts from the red-alga Gracillaria chilensis prevent the growth of Phytophthora cinnamomi, showing a response which depends on doses and collecting-time. Similarly, aqueous and ethanolic extracts from the brown-alga Durvillaea antarctica were able to diminish the damage caused by tobacco mosaic virus (TMV) in tobacco leaves, and the aqueous procedure is, in addition, more effective and seasonally independent. These results suggest that macro-algae contain compounds with different chemical properties which could be considered for controlling specific plant pathogens

Weight Care Project: Health professionals' attitudes and ability to assess body weight status - Study protocol

<p>Abstract</p> <p>Background</p> <p>Health professionals working in primary care and public health have opportunities to address body weight status issues with their patients through face-to-face contact. The objectives of this all-Ireland project are: 1. to assess the attitudes, current practices/behaviours and knowledge of key health professional groups on body weight status; 2. to assess the health professional groups' ability to identify body weight status in both adults and children. The health professional groups are: (a) community related public health nurses; (b) school public health nurses; (c) GPs and practice nurses (primary care); and (d) occupational health nurses (workplace) from both Northern Ireland and the Republic of Ireland.</p> <p>Methods/Design</p> <p>This all-Ireland multi-disciplinary project follows a mixed methods approach using both quantitative and qualitative methodologies, and consists of four components:</p> <p>1. Literature review - to explore the role of health professionals in managing obesity through spontaneous intervention in a variety of health promotion settings.</p> <p>2. Telephone interviews and focus groups - to gain an in-depth insight into the views of health professionals in assessing body weight status.</p> <p>3. Survey (primarily online but also paper-based) - to determine the attitudes, current practices/behaviours and knowledge of health professionals in assessing body weight status.</p> <p>4. Online evaluation study - an online interactive programme will be developed to assess health professionals' ability to identify the body weight status of adults and children.</p> <p>Discussion</p> <p>This project will assess and report the attitudes, current practices/behaviours and knowledge of key health professional groups within Northern Ireland and the Republic of Ireland on body weight status, and their ability to identify body weight status in both adults and children. The results of this project will generate recommendations for clinical practice in managing obesity, which may inform policy guidelines.</p

HIV sero-positivity and risk factors for ischaemic and haemorrhagic stroke in hospitalised patients in Uganda : A prospective-case-control study

OBJECTIVES: We examined HIV sero-positivity and risk factors in patients admitted with ischaemic stroke (IS) and haemorrhagic stroke (HS) in Kampala, Uganda. STUDY DESIGN: We conducted a matched case-control study between December 2016 and December 2018 at St Francis Hospital, Nsambya. METHODS: The study population comprised of stroke cases (adults aged ?18 years with IS or HS confirmed by neuroimaging) and controls (age- and sex-matched stroke-free adults aged ?18 years who were recruited from the same hospital as the cases). A comprehensive assessment for sociodemographic, lifestyle and clinical factors was performed using the World Health Organization (WHO) STEP-wise approach to Surveillance (STEPS) for stroke risk factor surveillance. We used conditional logistic regression to identify risk factors associated with IS or HS. RESULTS: We enrolled 137 matched case-control pairs; 48 (35 were men, and the mean ages were 62.4 years (SD $14.8) for cases and 61.1 years (SD$ 14.1) for controls. Of stroke patients, 86 (63 had IS and 51 (37 had HS. Overall, HIV sero-positivity was 10positivity was not significantly associated with stroke (unadjusted odds ratio [uOR] = 1.49, 95CI] 0.59?3.78). A self-reported family history of diabetes mellitus was associated with an increased risk of all stroke (adjusted odds ratio [aOR] = 4.41, 95.47?13.2), as well as for IS and HS separately (aOR = 3.66, 95.09?12.4 and aOR = 4.99, 95.02?24.4, respectively). High blood pressure (?140/90 mmHg) was associated with an increased risk of all stroke (aOR = 12.3, 952?44.1), and this was also true for IS and HS individually (aOR = 6.48, 95.15?36.7 and aOR = 5.63, 95.74?18.2, respectively). CONCLUSIONS: No association was found between HIV sero-positivity and stroke occurrence among Ugandan stroke patients. Hypertension and a self-reported family history of diabetes mellitus were significant risk factors for both IS and HS. Interventions to reduce hypertension and diabetes mellitus in the Ugandan population are urgently required. Much larger studies are required to demonstrate if any association exists between HIV and stroke
