Abstract Background Varicose vein disease (VVD) affects approximately one third of adults. Cure Conservatrice et Hémodynamique de l’Insuffisance Veineuse en Ambulatoire (CHIVA) is a minimally ...invasive, vein sparing technique that is emerging as an alternative to ablative techniques for treating VVD. Methods This prospective study assessed the rate of recurrence of venous reflux with CHIVA. We evaluated 150 primary procedures with clinical and duplex ultrasound examinations pre and post operatively. Patients were followed at <3 months and >1-year post-op. Recurrence was defined as reflux in the diseased vessel at the saphenofemoral junction on duplex examination. Results There was no documented recurrence at the early follow up. To date, 58 legs have completed the late follow up and reflux was found in 5 legs resulting in a recurrence rate of 8.6%; 95% CI (2.4%, 19%). Conclusion Our results indicate that CHIVA appears to offer a promising alternative for the treatment of VVD.
IntroductionObesity and type 2 diabetes mellitus (T2DM) are growing global health concerns associated with significant morbidity, mortality and healthcare expenditures. Due to histories of ...colonisation and contemporary marginalisation, Canada’s Indigenous populations are disproportionately burdened by obesity, T2DM and many other chronic illnesses. Culturally appropriate research on experiences and outcomes of Indigenous patients undergoing bariatric surgery in Canada is scarce. This qualitative study protocol will use a decolonising approach guided by an Indigenous Elder to explore the perspectives and experiences of urban Indigenous Manitobans with respect to T2DM, obesity and bariatric surgery. This knowledge will guide the development and implementation of culturally sensitive bariatric care.Methods and analysisSequential sharing circles (SSCs) and semistructured conversational interviews that have been purposefully designed to be culturally relevant with the guidance of an Indigenous Elder and advisory group (IAG) will be carried out in Winnipeg, Manitoba, Canada. Indigenous adults who are obese (body mass index >35 kg/m2), have T2DM and live in an urban centre will be recruited. Three groups will be investigated: (1) those who have had bariatric surgery; (2) those on the wait list for bariatric surgery and (3) those not associated with a bariatric surgery programme. Each group of 10–12 participants will be guided through a semistructured script led by an Indigenous Elder. Elder-facilitated conversational interviews will also be completed following the SSCs. All content will be audio recorded and transcribed. Thematic analysis will be used to identify emerging patterns using a constructive grounded theory approach.Ethics and disseminationThis study has received ethical approval from the University of Manitoba Health Research Ethics Board. Findings will inform the development and implementation of culturally sensitive programmes at Manitoba’s Centre for Metabolic and Bariatric Surgery. Results will be disseminated in peer-reviewed scientific journals, at obesity and Indigenous health conferences, and knowledge sharing ceremonies.
Trichobezoars are foreign bodies in the gastrointestinal tract composed of ingested hair. These can develop into large, hard, obstructing objects that are often impossible to remove endoscopically. ...The size often leads surgeons to remove these via laparotomy or laparoscopic-assisted procedure (midline laparotomy for specimen removal), with few removed completely laparoscopically.
We present a case of a 5-year-old female with pica who had symptoms of foul-smelling diarrhea and weight loss and was found to have a massive gastric trichobezoar. The bezoar was removed laparoscopically with pfannensteil incision facilitating specimen extraction. Further, technical aspects of the procedure are discussed.
We conclude that there are benefits to using a laparoscopic approach to remove a massive gastric trichobezoar. This includes the use of a Pfannensteil incision rather than a midline laparotomy for specimen removal.
•Case Presentation: 5yo female with a massive gastric trichobezoar.•Description of laparoscopic removal of massive gastric trichobezoar.•Discussion of various technical considerations.•Laparoscopic removal of trichobezoars is safe and effective.•Pfannensteil incision should be considered over midline laparotomy.
•Supplementation with structure-forming hydrocolloids provides stable foams based on the whey protein concentrate.•Xanthan gum is the most potent foam-stabilizing factor.•Foams originating from whey ...protein concentrate and hydrocolloids show a behavior of viscoelastic solids.
The aim of current work was to obtain stable foams that are based on the whey proteins concentrate and selected hydrocolloids. The basic physical (density, volume fraction of gas, equivalent diameters etc.) and rheological properties of the stable foams based on WPC and hydrocolloids such as xanthan gum, gum arabic and carrageenan were determined. The osmotic properties of the starting aqueous mixtures of WPC and selected hydrocolloids were examined. The results of the research provided insights into the nature of the interactions between water-soluble whey proteins and structure-forming hydrocolloids. The time constants of the rheological exponential equation of the state of shear-thinned liquids (De Kee equation) were determined and the influence of the temperature on the apparent viscosity of the foams was analyzed. Supplementation with structure-forming hydrocolloids such as xanthan gum, gum arabic or carrageenan contributes to the generation of stable foams, with rheological properties typical for viscoelastic solids in the linear range of viscoelasticity. The presence of hydrocolloids stimulates time-dependent nature of foams and manifests in hysteresis of flow curves.
•Sauter diameter and the PDI of the bubble sizes are dependent on the methylation degree.•The Kolmogorov–Smirnov test is an effective tool to analysis population gas bubbles in foam.•The log-normal ...distribution provided the best description of the bubbles distributions.
The study analyzed the influence of the degree of apple pectin methylation and the concentration of xanthan gum on physicochemical properties of fresh wet egg white protein based foams. Molecular characterization of applied hydrocolloids was performed and amino acid composition of proteins was established. First, essential physicochemical properties of the starting solutions, i.e. density, surface tension and hydrophobicity, were analyzed, and electrophoretic analysis of the solutions was carried out. Density and content of the gaseous phase in the continuous phase were determined. The image analysis allowed assessment of the size distributions of gas bubbles and, subsequently, cross compliance of the population of obtained bubbles was performed using the Kolmogorov–Smirnov test. Next, using the maximum likelihood method, three distributions, i.e. Weibull, log-normal and gamma distributions, were matched to one another. The results showed that the log-normal distribution provided the best description of the bubble distribution.
Selected rheological properties of acetylated starch pastes of different amylose content were discussed in the study. The rheological studies were carried out immediately after the preparation of the ...pastes as well as after 1 and 7 days of storage. For the paste of acetylated potato starch (P‐A), a phenomenon of oscillatory changes of viscosity with time was observed. The pastes of the acetylated amylostarch (AMY‐A) and acetylated waxy potato starch (AP‐A) exhibited the phenomenon of thixotropy. Based on the flow curves, the distribution of the time constants of the exponential rheological equation of state has been determined. They served to describe the contributions forming rheological properties. It has been noticed that during shear the phenomenon of the energy dissipation is predominant in AMY‐A (rheological characteristic time of 0.3 s) and AP‐A, whereas the elastic contributions are specific for the paste of acetylated potato starch (rheological characteristic time of 10⁻⁶ s). In order to describe the structural changes of AMY‐A and AP‐A pastes during flow, i.e. for the systems exhibiting frictional properties, the Cheng and Evans viscous structural theory has been applied. The rheological properties were then interpreted in light of the results of chromatographic and osmometric analyses.
Miód charakteryzuje się unikatowymi właściwościami sensorycznymi i prozdrowotnymi. W skład miodu wchodzą między innymi przeciwutleniacze, enzymy, witaminy, makro- i mikroelementy, które kształtują ...jego aktywność biologiczną i odgrywają kluczową rolę w prawidłowym funkcjonowaniu organizmu. Miody stanowią źródło potasu, magnezu, wapnia, sodu, siarki, manganu, żelaza, wanadu, chromu, fosforu, srebra, boru i miedzi. Celem pracy było określenie składu mineralnego miodów odmianowych dostępnych na polskim rynku. W badaniach użyto polskich miodów różnych odmian: akacjowego, wielokwiatowego, lipowego i rzepakowego. Ocenie poddano miody zakupione w supermarkecie i pochodzące bezpośrednio z pasieki. Średnia zawartość Ca, K, Na, Mg, Mn, Zn, Cu i Fe w miodach wynosiła odpowiednio mg/100 g: 7,42, 59,66, 1,57, 1,44, 0,11, 0,46, 0,02 i 0,12. Największą zawartością makro- i mikroelementów charakteryzował się miód wielokwiatowy pochodzący bezpośrednio z pasieki – 133,77 mg/100 g. Najmniejszą zawartość składników mineralnych wykazano w miodzie akacjowym zakupionym w supermarkecie – 27,23 mg/100 g. Dodatkowo przeanalizowano wpływ położenia prywatnej pasieki w okolicach Huty Miedzi Głogów na zawartość miedzi w próbach miodów różnych odmian. Nie stwierdzono statystycznie istotnej różnicy (p ≥ 0,05) pomiędzy średnią zawartością miedzi w miodach komercyjnych i w miodach z prywatnej pasieki, co wskazuje na brak wpływu pochodzenia geograficznego na zawartość tego pierwiastka.
