    A second-generation solar disinfection (SODIS) system (pouch) was constructed from food-grade, commercially available packaging materials selected to fully transmit and amplify the antimicrobial properties of sunlight. Depending upon the season, water source, and challenge organism, culturable bacteria were reduced between 3.5 and 5.5 log cycles. The system was also capable of reducing the background presumptive coliform population in nonsterile river water below the level of detection. Similar experiments conducted with a model virus, the F-specific RNA bacteriophage MS2, indicated that the pouch was slightly less efficient, reducing viable plaques by 3.5 log units in comparison to a 5.0 log reduction of enterotoxigenic Escherichia coli O18:H11 within the same time period. These results suggest that water of poor microbiological quality can be improved by using a freely available resource (sunlight) and a specifically designed plastic pouch constructed of food-grade packaging materials.

    Full Text Available Over a period of 5-year (May 2000 to April 2005 29 patients of congenital pouch colon (CPC were managed by single pediatric surgeon in the Department of Pediatric Surgery of a tertiary hospital. Of these, 11 were girls (M: F: 1.6:1. Detailed anatomy could be studied in nine patients, were included in this study. Age of presentation in female subjects ranged 1 day to 8 years. On examination, eight of the nine patients had single perineal opening suggesting a very high incidence of association of cloaca in female subjects with CPC. Four had short urogenital sinus with colonic pouch opening in the posterior wall of urinary bladder. In other two patients, CPC terminated in short cloaca. Anomalies of mullerian structures such as uterus didelphus and septate vagina ware commonly encountered. Proximal diversion with or without pouch excision was done as the initial preliminary treatment for all those patients who presented in early life. Of the nine girls, two died after the preliminary surgery. Only five patients have undergone definitive surgery. Definitive surgery included abdomino-perineal pull-through of proximal normal colon ( n =2, tubularization of pouch with abdomino- posterior sagittal- pull through ( n =2 and abdomino-posterior sagittal urethra-vaginoanorectoplasty with pull through of tapered pouch colon in one patient. Two of these patients had concomitant bowel vaginoplasty. Three patients with tubularized pouches had constipation and spurious diarrhea. However, good pseudo-continence of bowel was achieved on regular bowel washes. The cosmetic appearance of perineum in all these three patients was acceptable. The patients in whom pouch excision was done had diarrhea and severe perineal excoriation resistant to conservative management.

    2016-08-01

    Full Text Available Introduction The restorative proctocolectomy (RPC with ileal pouch-anal anastomosis (IPAA is currently the preferred surgical method for most patients with ulcerative colitis and familial adenomatous polyposis and sometimes, functional bowel diseases. Infection around the pouch, remaining rectal stump, stricture at anastomosis site, pouch dysfunction and refractory pouchitis can lead to pouch failure. Pouch salvage surgery could prevent pouch failure in some cases. Case Presentation In this report, five patients were introduced, who underwent pouch salvage surgery after RPC/IPAA surgery failure. Two of the patients were male and three were female and the relevant age range was 16 to 41. Initially, RPC/IPAA surgery was performed on these five patients. Four of the patients underwent RPC/IPAA surgery as a result of ulcerative colitis and, one of the patients as a result of familial adenomatous polyposis. However, due to pouch failure from the RPC/IPAA surgery, pouch-salvage surgery was performed on each of these five patients. Two of the patients underwent pouch-salvage surgery due to infection and pouch fistula, and the other three underwent this surgery due to the remaining rectal stump, anastomosis stenosis and pouch dysfunction. The average time for when pouch-salvage surgery was performed was 3.5 years (three months to five years after the initial operation and the patients were under follow-up care for two to seven years. Conclusions After performing pouch salvage operation, pouch function was acceptable in all patients and we could close ileostomies of all of them.

    To evaluate whether the current Canadian tritium drinking water limit is protective of aquatic biota, an in vitro study was designed to assess the biological effects of low concentrations of tritium, similar to what would typically be found near a Canadian nuclear power station, and higher concentrations spanning the range of international tritium drinking water standards. Channel catfish peripheral blood B-lymphoblast and fathead minnow testis cells were exposed to 10-100,000 Bq l(-1) of tritium, after which eight molecular and cellular endpoints were assessed. Increased numbers of DNA strand breaks were observed and ATP levels were increased. There were no increases in γH2AX-mediated DNA repair. No differences in cell growth were noted. Exposure to the lowest concentrations of tritium were associated with a modest increase in the viability of fathead minnow testicular cells. Using the micronucleus assay, an adaptive response was observed in catfish B-lymphoblasts. Using molecular endpoints, biological responses to tritium in the range of Canadian and international drinking water standards were observed. At the cellular level, no detrimental effects were noted on growth or cycling, and protective effects were observed as an increase in cell viability and an induced resistance to a large challenge dose.

    Binge drinking is a public health concern due to its association with negative health outcomes as well as increased legal and social consequences. Previous studies have frequently used self-reported alcohol consumption to classify binge drinking episodes; however, these measures are often limited in both detail and accuracy. Some researchers have begun using additional measures such as blood (BAC) and breath (BrAC) alcohol concentrations to supplement self-report data. Transdermal alcohol testing, or the detection of alcohol expiration through the skin, offers advantages over BAC and BrAC measures by allowing for continuous and noninvasive monitoring of an individual's drinking behavior in real time. Despite these advantages, this technology has not been widely used or studied outside of forensic applications. The present research compares transdermal alcohol concentration (TAC) and BrAC readings during the consumption of alcohol ranging from moderate drinking to binge drinking in 22 adult regular drinkers in order to investigate the sensitivity and specificity of the TAC monitors. We observed that BrAC and TAC measures were broadly consistent. Additionally, we were able to develop an equation that could predict BrAC results using TAC data, indicating TAC data would be an appropriate substitute in research and clinical contexts where BrAC readings are typically used. Finally, we were able to determine a cutoff point for peak TAC data that could reliably predict whether a participant had engaged in moderate or more-than-moderate drinking, suggesting TAC monitors could be used in settings where moderate or reduced drinking is the goal.

    Shelf life of pasteurized milk in Brazil ranges from 3 to 8 d, mainly due to poor cold chain conditions that prevail throughout the country and subject the product to repeated and/or severe temperature abuse. This study evaluated the influence of storage temperature on the microbiological stability of homogenized whole pasteurized milk (75 degrees C/15 s) packaged in high-density polyethylene (HDPE) bottle and low-density polyethylene (LDPE) pouch, both monolayer materials pigmented with titanium dioxide (TiO(2)). The storage temperatures investigated were 2, 4, 9, 14, and 16 degrees C. Microbiological evaluation was based on mesophilic and psychrotrophic counts with 7 log CFU/mL and 6 log CFU/mL, respectively, set as upper limits of acceptability for maintaining the quality of milk. The microbiological stability for pasteurized milk packaged in HDPE bottle and stored at 2, 4, 9, 14, and 16 degrees C was estimated at 43, 36, 8, 5, and 3 d, respectively. For milk samples packaged in LDPE pouch, shelf life was estimated at 37, 35, 7, 3, and 2 d, respectively. The determination of Q(10) and z values demonstrated that storage temperature has a greater influence on microbiological shelf life of pasteurized milk packaged in LDPE pouch compared to HDPE bottle. Based on the results of this study, HDPE bottle was better for storing pasteurized milk as compared to LDPE pouch.

    The purpose of this study was to describe our experience with six patients who developed Crohn's disease in the ileal pouch or distal ileum after a total proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis. Pouch enemas showed characteristic findings of Crohn's disease, including nodularity, thickened folds, ulceration, cobblestoning, strictures, sinus tracks, and fistulas to the perianal region and vagina. It is important for radiologists to be aware of the findings of Crohn's disease in the ileal pouch and distal ileum on radiographic studies of the pouch after total proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis because of the implications for patient management.

    Giant African pouched rats equipped with video cameras may be a tenable option for locating living humans trapped under debris from collapsed structures. In the present study, 5 pouched rats were trained to contact human targets in a simulated collapsed building and to return to the release point after hearing a signal to do so. During test sessions, each rat located human targets more often than it located similar-sized inanimate targets on which it had not previously been trained and spent more time within 1 m of the human target than within 1 m of the other targets. Overall, the rats found humans, plastic bags containing clothes, and plastic bags without clothes on 83%, 37%, and 11% of trials, respectively. These findings suggest that using pouched rats to search for survivors in collapsed structures merits further attention. © Society for the Experimental Analysis of Behavior.

    Consumption of ready-to-drink beverages, as a potential source of fluoride (F), has increased considerably in China over the last decade. To help inform the public and policy makers, this study aimed to measure F concentration of ready-to-drink beverages on sale in Heilongjiang province, north east China. Three batches of 106 drink products manufactured by 26 companies were purchased from the main national supermarkets in Harbin, Heilongjiang province, China. The F concentration of all samples was determined, in triplicate, using a fluoride ion-selective electrode in conjunction with a meter and a direct method of analysis. The products were categorised into 10 groups according to product type. F concentrations of the samples ranged from 0.012-1.625 mg/l with a mean of 0.189 mg/l and a median of 0.076 mg/l. More than half of the products (55%) had an F concentration of ≤0.1 mg/l, while 0.7 mg/l. The 'tea with milk' group contained the highest mean F concentration (1.350 mg/l), whereas the lowest mean F concentration (0.027 mg/l) was found for the 'fruit juice' group. For some products, such as tea, fruit juice and carbonated beverages, there were substantial variations in F concentration between batches, manufacturers and production sites. In conclusion, ready-to-drink products (apart from tea), sold in Heilongjiang province, China, when consumed in moderation are unlikely to constitute a substantial risk factor for the development of dental or skeletal fluorosis.

    The aim of the study was to investigate pouch motility and evacuation under standardised conditions with a minimum of external influence. Ileal J-pouches had been constructed 30 cm proximal to the ileocecal valve in 10 dogs (6 pelvic/4 gastric configuration). After 8 weeks the following examinations were performed: (1) measurement of pouch compliance by balloon distension, (2) measurement of pouch contractions by strain gauge transducers, (3) radiological imaging of pouch contractions and evacuation, (4) evacuation scintigraphy and (5) radiological determination of small intestinal transit time. Compliance (2.3 +/- 1.1 mmHg/ml) and small intestinal transit time (31.6 +/- 7.5 h) were significantly higher in the pouch group than in controls (0.5 +/- 0.2 mmHg/ml, 8.0 +/- 2.8 h; p evacuation (t(1/2) = 109 +/- 52 min). Strain gauge measurements revealed irregular pouch contractions without detectable propagation. Contraction amplitudes (40.4 +/- 22.9 g) and frequencies (10.4 +/- 1.0/min) were equal all over the pouch. There were no functional differences between gastric and pelvic pouch configuration. Small intestinal pouches act as reservoirs. Uncoordinated motility patterns contribute to this function. Other factors than pouch motility are responsible for evacuation.

    PURPOSE: We characterized the expression of sialomucin and sulphomucin in pouches fashioned for familial adenomatous polyposis and ulcerative colitis. We correlated sulphomucin expression with bacterial colonization and mucosal inflammation. METHODS: Ethical approval and informed consent were obtained. Mucosal biopsies from 9 patients with familial adenomatous polyposis and 12 with ulcerative colitis were obtained. Sulphomucin levels were assessed by using the high iron-diamine stain. Mucous gel layer composition was correlated with villous height, crypt depth, and total mucosal thickness. Mucous gel layer composition was correlated with acute and chronic inflammatory infiltrates. Colonization by a panel of seven bacterial species (including sulphate reducing bacteria) was established and correlated with sulphomucin levels. RESULTS: High-iron-diamine positivity (i.e., sulphomucin expression) was greater in ulcerative colitis pouch mucous gel (2.083 +\\/- 0.5 vs. 0.556 +\\/- 0.4, P = 0.003). Sulphomucin expression correlated with reduced crypt depth, villous height, and total mucosal thickness. In the ulcerative colitis group, chronic inflammatory infiltrate scores were significantly greater for high-iron-diamine-positive patients. Colonization by sulphate reducing bacteria was increased in high-iron-diamine-positive patients. CONCLUSIONS: Sulphomucin expression is increased in the mucous gel layer of the ulcerative colitis pouch compared with that of the familial adenomatous polyposis pouch. Sulphomucin expression is associated with colonization by sulphate-reducing bacteria and increased chronic inflammation.

    Full Text Available Setting. Tanzania. Objective. To compare microscopy as conducted in direct observation of treatment, short course centers to pouched rats as detectors of Mycobacterium tuberculosis. Design. Ten pouched rats were trained to detect tuberculosis in sputum using operant conditioning techniques. The rats evaluated 910 samples previously evaluated by smear microscopy. All samples were also evaluated through culturing and multiplex polymerase chain reaction was performed on culture growths to classify the bacteria. Results. The patientwise sensitivity of microscopy was 58.0%, and the patient-wise specificity was 97.3%. Used as a group of 10 with a cutoff (defined as the number of rat indications to classify a sample as positive for Mycobacterium tuberculosis of 1, the rats increased new case detection by 46.8% relative to microscopy alone. The average samplewise sensitivity of the individual rats was 68.4% (range 61.1–73.8%, and the mean specificity was 87.3% (range 84.7–90.3%. Conclusion. These results suggest that pouched rats are a valuable adjunct to, and may be a viable substitute for, sputum smear microscopy as a tuberculosis diagnostic in resource-poor countries.

Patients and Methods: This retrospective study included CPC cases that were managed with two-staged procedures in the Department of Paediatric Surgery, over a period of 12 years from 1 January 2000 to 31 December 2011. Results: CPC comprised of 13.71% (97 of 707 of all anorectal malformations (ARM and 28.19% (97 of 344 of high ARM. Eleven CPC cases (all males were managed with two-staged procedures. Distribution of cases (Narsimha Rao et al.′s classification into types I, II, III, and IV were 1, 2, 6, and 2, respectively. Initial operative procedures performed were window colostomy (n = 6, colostomy proximal to pouch (n = 4, and ligation of colovesical fistula and end colostomy (n = 1. As definitive procedures, pouch excision with abdomino-perineal pull through (APPT of colon in eight, and pouch excision with APPT of ileum in three were performed. The mean age at the time of definitive procedures was 15.6 months (ranges from 3 to 53 months and the mean weight was 7.5 kg (ranges from 4 to 11 kg. Good fecal continence was observed in six and fair in two cases in follow-up periods, while three of our cases lost to follow up. There was no mortality following definitive procedures amongst above 11 cases. Conclusions: Two-staged procedures for all types of CPC can also be performed safely with good results. The most important fact that the definitive procedure is being done without protective stoma and therefore, it avoids stoma closure, stoma-related complications, related cost of stoma closure and hospital stay.

    The definitive operation for chronic ulcerative colitis (UC) and familial adenomatous polyposis is total proctocolectomy with ileal pouch-anal anastomosis (IPAA). Mild inflammation (pouchitis) is omnipresent in pouches and becomes severe in 50% of UC patients with IPAA. The etiology of pouchitis is likely due to combined genetic, microbial, and immunologic factors. Epithelial cell exposure to surgical trauma and/or to changes in intestinal bacterial composition may account for the inflammatory infiltrate. Progress in understanding pouchitis is restricted by the lack of suitable animal models. An ileal pouch-rectal anastomosis [IPRA] in rats was developed to reproduce a model of human IPAA and clinical, gross and histologic criteria were determined. Many shared features with human ileal pouch were observed. IPRA is an important in vivo model to study mechanisms of repair, defense and immunity that may contribute to pouchitis.

    This study was intended to determine whether J-pouch irrigations through the efferent limb of the protective ileostomy stoma after ileoanal pull-through are effective in decreasing high stool frequency after ileostomy closure. Patients undergoing ileoanal pull-through may have high stool frequency after ileostomy closure. J-pouch irrigations through the efferent ileostomy stoma may decrease stool frequency by increasing J-pouch volume, improving storage capacity. The study used a randomized, prospective design in a university hospital outpatient setting. Participants (N = 58) were randomly assigned to control and experimental groups. Effectiveness of irrigation was determined by stool frequency. Both groups were taught Kegel exercises (anal muscle strengthening exercises). The experimental group was taught how and when to irrigate the J-pouch daily; the control group was not. Forty-seven subjects, 25 men and 22 women ranging in age from 15 to 65 years, completed the study. Results of MANOVA indicated no significant between-group difference in the average number of times that subjects performed Kegel exercises; however, there was a significant decrease during the 4-week study period (p < 0.001). There was no significant difference between groups in stool frequency, which decreased with time. There also was no significant effect on nocturnal leakage or satisfaction with surgical outcome. Additional clinical variables that were measured but had no significant effect included eating late, pouch size, and intake of sugar, fiber, bulk-forming products, and antidiarrheal agents. The study did not support the effectiveness of J-pouch irrigation in decreasing stool frequency after ileostomy closure. The cost, time commitment, and burden of performing daily irrigations are not warranted in this patient group.

    Full Text Available Background: The gall bladder is a hollow pear shaped sac lying within a fossa on the visceral surface of the right lobe of the liver. In the junction of neck of the gallbladder and the cystic duct, there is a pouch present called Hartman’s pouch or infundibulum of the gallbladder which is a frequent but inconstant feature of the normal gallbladder. It is the common site of lodged gallstones. Objective: To determine the proportion of presence of Hartman’s pouch in our population so that the concerned personnel might have a thought in mind that common pathologies of gall bladder may also involve this pouch. Materials and method: This cross sectional study was carried out in the department of Anatomy, Sir Salimullah Medical College & Mitford Hospital, Dhaka, Bangladesh, from July 2010 to June 2011. The number of sample was 62 postmortem human gallbladders which were collected from unclaimed dead bodies. Results: Hartmann’s pouch of the gallbladder was found in 45 (72.58%. Conclusion: Hartman’s pouch is present in a good proportion of our population.

    In Taiwan, oral cancer has becomes the fastest growth male cancer disease due to the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people. In order to eliminate the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when ALA reached its peak level in the lesional epithelial cells after topical application of ALA gel. We found that ALA reached its peak level in precancerous lesions about 2.5 hrs after topical application of ALA gel. The cancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 150 J/cm2 using LED 635 nm fiber-guided light device. Visual examination demonstrated that adjuvant topical ALA -mediated PDT group has shown better therapeutic results in compared to those of non-adjuvant topical ALA-mediated PDT group for DMBA-induced hamster buccal pouch precancerous lesions.

    Oral cancer has becomes the most prominent cancer disease in recent years in Taiwan. The reason is the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people results in oral cancer becomes the fastest growth incident cancer amongst other major cancer diseases. In previous studies showed that photosan, haematoporphyrin derivative (HPD), has demonstrated effective PDT results on human head and neck disease studies. To avoid the systemic phototoxic effect of photosan, this study was designed to use a topical photosan-mediated PDT for treatment of DMBA-induced hamster buccal pouch cancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical photosan-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when photosan reached its peak level in the lesional epithelial cells after topical application of photosan gel. We found that photosan reached its peak level in cancerous lesions about 13.5 min after topical application of photosan gel. The cancerous lesions in hamsters were then treated with topical photosan-mediated PDT (fluence rate: 600 mW/cm2; light exposure dose 200 J/cm2) using the portable Lumacare 635 nm fiber-guided light device. Visual examination demonstrated that topical photosan-mediated PDT was an applicable treatment modality for DMBA-induced hamster buccal pouch cancerous lesions.

    To determine in the hamster cheek pouch whether or not the changes in plasma extravasation induced by vascular endothelial growth factor (VEGF) could be affected by fructose diet. Hamsters were subjected to control drinking water or to water containing fructose (10 %) for 18 weeks. The fructose diet induced a small but significant increase in glycemia (0.80+/-0.11 and 1.09+/-0.15, n=8 and 9 for control and fructose- treated animals, respectively, Pdiet while the effects of VEGF were markedly increased (maximal number of leakage sites: 76+/-20 and 126+/-55, n = 8 and 9 for control and fructose-treated animals, respectively, P<0.01). Even moderate changes in glycemic levels can produce profound alteration in the VEGF response.

    ACKGROUND: Previous studies have indicated that pouch volume and stoma size are two important factors related to weight loss after laparoscopic gastric banding in morbid obese patients. We hypothesized that there was association among the wall stress, pouch volume, and stoma size in a model...... for the filling and emptying phases of the pouch. METHODS: A numerical pouch model with variable pouch volume and stoma size was generated. Uniaxial tensile testing was performed on fundus strips from fresh pig stomach and the mass flow of filling and emptying of the pouch was simulated numerically. RESULTS......Pa in the pouch wall at the same degree of filling. Decreasing the stoma diameter from 27 to 10 mm caused an increase of the maximum circumferential stress from 11.46 to 12.78 kPa and a decrease of the maximum longitudinal stress from 10.34 to 8.69 kPa. CONCLUSION: Both the pouch volume and stoma size...

    PURPOSE: Ileal pouch-anal anastomosis remains the "gold standard" in surgical treatment of ulcerative colitis and familial adenomatous polyposis. Pouchitis occurs mainly in patients with a background of ulcerative colitis, although the reasons for this are unknown. The aim of this study was to characterize differences in pouch bacterial populations between ulcerative colitis and familial adenomatous pouches. METHODS: After ethical approval was obtained, fresh stool samples were collected from patients with ulcerative colitis pouches (n = 10), familial adenomatous polyposis (n = 7) pouches, and ulcerative colitis ileostomies (n = 8). Quantitative measurements of aerobic and anaerobic bacteria were performed. RESULTS: Sulfate-reducing bacteria were isolated from 80 percent (n = 8) of ulcerative colitis pouches. Sulfate-reducing bacteria were absent from familial adenomatous polyposis pouches and also from ulcerative colitis ileostomy effluent. Pouch Lactobacilli, Bifidobacterium, Bacteroides sp, and Clostridium perfringens counts were increased relative to ileostomy counts in patients with ulcerative colitis. Total pouch enterococci and coliform counts were also increased relative to ileostomy levels. There were no significant quantitative or qualitative differences between pouch types when these bacteria were evaluated. CONCLUSIONS: Sulfate-reducing bacteria are exclusive to patients with a background of ulcerative colitis. Not all ulcerative colitis pouches harbor sulfate-reducing bacteria because two ulcerative colitis pouches in this study were free of the latter. They are not present in familial adenomatous polyposis pouches or in ileostomy effluent collected from patients with ulcerative colitis. Total bacterial counts increase in ulcerative colitis pouches after stoma closure. Levels of Lactobacilli, Bifidobacterium, Bacteroides sp, Clostridium perfringens, enterococci, and coliforms were similar in both pouch groups. Because sulfate-reducing bacteria are

    The hamster buccal pouch (HBP) carcinogenesis model is one of the most well-characterized animal tumor models used as a prelude to investigate multistage oral carcinogenesis and to assess the efficacy of chemointervention. Hamster buccal pouch carcinomas induced by 7,12-dimethylbenz[a]anthracene (DMBA) show extensive similarities to human oral squamous cell carcinomas. The HBP model offers a number of advantages including a simple and predictable tumor induction procedure, easy accessibility for examination and follow-up of lesions, and reproducibility. This model can be used to test both chemopreventive and chemotherapeutic agents.

    This study investigated possible determinants of food intake change after gastroplastry. Preoperatively and 6 and 12 months postoperatively, 27 morbidly obese patients were prospectively examined with 7-day food registration and radiologic measurement of pouch volume and stoma diameter. Pouch...... emptying was determined as the mean transit time by a scintigraphic method. None of the measured variables was found to influence the change in food intake taking place during the first 6 months, when most of the weight loss was observed. Between 6 and 12 months, the change of stoma diameter was positively...... associated with the change of solid foods consumed (by weight, p = 0.01; by energy content, p = 0.02). The change of pouch volume was negatively associated with the change of energy from beverages (p = 0.005). In conclusion, it seems impossible to tailor the reduction of food intake through adjustments...

    To evaluate the disease course and management strategy for pouch neoplasia. Patients undergoing ileal pouch surgery for underlying ulcerative colitis who developed low-grade dysplasia (LGD), high-grade dysplasia, or adenocarcinoma in the pouch were identified. All eligible 44 patients were evaluated. Of the 22 patients with initial diagnosis of pouch LGD, 6 (27.3%) had persistence or progression after a median follow-up of 9.5 (4.1-17.6) years. Family history of colorectal cancer was shown to be a risk factor associated with persistence or progression of LGD (P = 0.03). Of the 12 patients with pouch high-grade dysplasia, 5 (41.7%) had a history of (n = 2, 16.7%) or synchronous (n = 4, 33.3%) pouch LGD. Pouch high-grade dysplasia either persisted or progressed in 3 patients (25.0%) after the initial management, during a median time interval of 5.4 (2.2-9.2) years. Of the 14 patients with pouch adenocarcinoma, 12 (85.7%) had a history of (n = 2, 14.3%) or synchronous dysplasia (n = 12, 85.7%). After a median follow-up of 2.1 (0.6-5.2) years, 6 patients with pouch cancer (42.9%) died. Comparison of patients with a final diagnosis of pouch adenocarcinoma (14, 32.6%), and those with dysplasia (29, 67.4%) showed that patients with adenocarcinoma were older (P = 0.04) and had a longer duration from IBD diagnosis or pouch construction to the detection of pouch neoplasia (P = 0.007 and P = 0.0013). The risk for progression of pouch dysplasia can be stratified. The presence of family history of colorectal cancer seemed to increase the risk for persistence or progression for patients with pouch LGD. The prognosis for pouch adenocarcinoma was poor.

    2009-10-01

    Several surgical techniques, such as the papilla preservation flap, the modified papilla preservation flap, and the sulcular incision flap, have attempted to achieve clot stabilization and graft coverage in an attempt to regenerate lost tissue due to periodontal disease. This case report focuses on soft tissue root coverage and bone regeneration in a one-wall osseous defect using the pouch-and-tunnel surgical procedure. The pouch-and-tunnel surgical technique is a minimally invasive periodontal plastic surgical procedure that uses subepithelial connective tissue as a free graft in a pouch beneath the gingival margin, created by sulcular incisions around the involved teeth. The autogenous bone graft placed in this one-wall osseous defect through a sulcular incision after root planing is protected in a stable pouch-like recipient site with an abundant blood supply. The free connective tissue graft also prevents epithelial migration into the recipient site. The use of Emdogain may help with cementogenesis around the planed root surface. This technique warrants further evaluation of cases with similar defects using this surgical procedure. (Int J Periodontics Restorative Dent 2009;29:515-521.).

    The experimental study of three types of intestinal pouch for slowing transit was carried out in the rat after resection of 75% of the small intestine. The consequences of these pouches are analysed compared with control animals have undergone the same resection alone. The slowing of the transit confirmed to opaque radiography of the small intestine was particularly marked in all three types of pouch. Statistical analysis of weight curves showed the existence of a favourable statistical difference for certain types of pouch from the fifth postoperative day onwards. Construction of pouches is in the rat one of the most effective procedures for slowing transit.

    2010-01-01

    Containing effluent from an enterocutaneous fistula (ECF) requires expertise, critical thinking skills, and creativity. Using a combination of products readily available to WOC nurses practicing in the United States, I have designed a suction pouch that reliably contains fistula output. A standard ostomy pouch can be converted into a suction pouch by adding a large, single-lumen catheter into the pouch, sealing it, and connecting the assembly to low continuous suction. The resulting pouch can be used by itself to drain effluent from an ECF or it can be used in combination with wound dressings, or a negative pressure wound therapy system. Application of a suction pouch extends the integrity of the appliance and diverts succus away from the wound bed or the newly applied skin graft with increased reliability. This article describes the technique used to create a suction pouch, followed by 4 brief case descriptions that demonstrate feasibility of its use for the management of ECFs.

    To evaluate changes in the distance between the distal rectal pouch and the perineum (pouch-perineum distance) from the birth day to the next day and to determine which day is better for diagnosis of a low-type imperforate anus in neonates. We reviewed medical records at our hospital from May 2003 to August 2015 and identified 9 neonates with a radiographically and surgically proven low-type imperforate anus and 9 with high/intermediate types of imperforate anus who had undergone sonography on both the birth day and the next day before the first surgical treatment. The sonograms were reviewed to measure the pouch-perineum distance at both examinations. The Wilcoxon signed rank sum test and a receiver operating characteristic curve analysis were used for the statistical analyses. The pouch-perineum distance on the next day (mean ± SD, 9.37 ± 4.89 mm; range, 2.1-20.9 mm) was significantly shorter than on the birth day (15.75 ± 6.67 mm; range, 8.1-37.2 mm; P = .001). The receiver operating characteristic analysis showed significantly better diagnostic performance (P perineum distance on the next day (area under the curve, 0.864) versus the birth day (0.420) for the low-type imperforate anus. The pouch-perineum distance was shorter on the next day than on the birth day, and the diagnostic performance of the pouch-perineum distance on the next day was significantly superior to that on the birth day for the diagnosis of a low-type imperforate anus. We recommend sonography on the next day in neonates with an imperforate anus when possible. © 2017 by the American Institute of Ultrasound in Medicine.

    2017-11-01

    After IPAA, 8% of patients with ulcerative colitis are later diagnosed with Crohn's disease of the pouch, associated with an increased rate of pouch failure. No study has reported on how often the clinical diagnosis is correlated with histologic findings of Crohn's disease in the excised pouch. The purpose of this study was to determine whether the clinical diagnosis is consistent with pathologic confirmation at pouch excision. The study was conducted at a tertiary IBD referral center. Patients with chronic ulcerative colitis who underwent pouch excision for presumed Crohn's disease of the pouch were included. Preoperative evaluation and pathologic variables at the time of pouch excision were measured. A total of 35 patients underwent pouch excision for Crohn's disease of the pouch based on a combination of clinical, radiographic, and endoscopic findings. Seven (20%) had surgical pathology consistent with Crohn's disease at pouch excision. There were no differences in those 7 patients and the remaining 28 in terms of diagnosis at colectomy, primary pouch symptoms, prepouch inflammation, ulceration, or granulomas at endoscopy. In the nonpathology-confirmed Crohn's disease, 40% (n = 11) had an anastomotic leak at time of IPAA versus 0% in the Crohn's disease group, and 86% (n = 24) had symptoms of pouch dysfunction within 5 months of ileostomy reversal versus 13 months in the Crohn's disease group. Of 28 without pathology-confirmed Crohn's disease, 100% (n = 28) were treated with antibiotics, 68% (n = 19) with steroids, 59% (n = 16) with immunomodulators, and 57% (n = 15) with biologic therapy for Crohn's disease of the pouch. The study was limited by its single-center scope and lack of an established definition for Crohn's disease of the pouch. Pathologic confirmation of Crohn's disease was given to only one fifth of patients who underwent pouch excision for Crohn's disease of the pouch. Given the histologic variability in Crohn's disease, it may be unreasonable to

    Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis (FAP). However, adenomas may develop in the ileal pouch mucosa over time, and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence, nature, and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed, the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated, but many remain controversial. Nevertheless, it seems certain that the age of the pouch is important. The risk appears to be 7% to 16% after 5 years, 35% to 42% after 10 years, and 75% after 15 years. On the other hand, only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years (median, 10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low, it is not negligible, and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance, especially using chromoendoscopy, is recommended. PMID:24187452

    Total gastrectomy causes numerous disorders, such as reflux esophagitis, dumping syndrome, malabsorption, and malnutrition. To minimize the consequences, different variants of reconstruction are performed. The aim of our study is the comparison of two reconstructive methods: the standard Roux-en-Y and a new modality of pouch interposition, preduodenal-pouch interposition. This study aims to investigate the advantage of bile reflux prevention and to reduce symptoms of dumping syndrome after 3- and 6-mo follow-up. A total of 60 patients were divided in two groups: (A) 30 patients with Roux-en-Y reconstruction, and (B) 30 patients with the preduodenal-pouch (PDP) type of reconstruction. Endoscopic examination and endoluminal jejunal limb pressure measurements were performed. Scintigraphic measurements of half-emptying time were performed to evaluate meal elimination in the context of reflux esophagitis and early dumping syndrome. The Japan Society of Gastrointestinal Surgery has provided guidelines with which to classify the symptoms of early dumping syndrome. Patients were followed up for periods of 3 and 6 mo after the surgery. Our study groups did not differ with regard to the level of reflux esophagitis (P = 0.688). Average values of pressure at 10 and 15 cm below the esophago-jejunal junction were significantly lower in the PDP group (P dumping syndrome symptoms revealed a significant reduction among PDP patients after 3 and 6 mo. Our study showed significant superiority of the new pouch reconstruction over the standard Roux-en-Y approach in the treatment of early dumping syndrome. Copyright © 2012 Elsevier Inc.

  3. How I do it: the stapled ileal J pouch at restorative proctocolectomy.

    Martin, S T

    2011-12-01

    Ileal pouch-anal anastomosis (IPAA) following proctocolectomy is the preferred option for patients with medically refractory ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis. However, it remains a procedure associated with morbidity and mortality. Pelvic sepsis, pouch fistulae, and anastomotic dehiscence predispose to pouch failure. We report our experience with an adaptation for the formation of the stapled ileal J pouch using the GIA™ 100 stapling device (Covidien, Mansfield, Massachusetts, USA). When creating the J pouch, we remove the bevelled plastic protector from the thin fork of the stapling device, allowing the staple line to be completed to the tip of the stapled efferent limb of the pouch, thereby minimizing potential blind ending in the efferent limb and injury to the transverse staple line.

    Oral cancer has becomes the most prominent male cancer disease due to the local betel nut chewing habit combing with smoking and alcohol-drinking lifestyle. In order to minimize the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch cancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 8 to 10 weeks. Precancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA -mediated PDT. We found that ALA reached its peak level in cancerous lesions about 2.5 hrs after topical application of ALA gel. The precancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 75 and 100 J/cm2 using LED 635 nm Wonderlight device. It is suggesting that optimization of the given light dose is critical to the success of PDT results.

    External carcinogens, such as tobacco and alcohol, induce molecular changes in large areas of oral mucosa, which increase the risk of malignant transformation. This condition, known as 'field cancerization', can be detected in biopsy specimens using histochemical techniques, even before histological alterations are identified. The efficacy of these histochemical techniques as biomarkers of early cancerization must be demonstrated in appropriate models. The hamster cheek pouch oral cancer model, universally employed in biological studies and in studies for the prevention and treatment of oral cancer, is also an excellent model of field cancerization. The carcinogen is applied in solution to the surface of the mucosa and induces alterations that recapitulate the stages of cancerization in human oral mucosa. We have demonstrated that the following can be used for the early detection of cancerized tissue: silver staining of nucleolar organizer regions; the Feulgen reaction to stain DNA followed by ploidy analysis; immunohistochemical analysis of fibroblast growth factor-2, immunohistochemical labeling of proliferating cells to demonstrate an increase of epithelial cell proliferation in the absence of inflammation; and changes in markers of angiogenesis (i.e. those indicating vascular endothelial growth factor activity, endothelial cell proliferation and vascular density). The hamster cheek pouch model of oral cancer was also proposed and validated by our group for boron neutron capture therapy studies for the treatment of oral cancer. Clinical trials of this novel treatment modality have been performed and are underway for certain tumor types and localizations. Having demonstrated the efficacy of boron neutron capture therapy to control tumors in the hamster cheek pouch oral cancer model, we adapted the model for the long-term study of field cancerized tissue. We demonstrated the inhibitory effect of boron neutron capture therapy on tumor development in field

    The Siberian taiga explosion of 30 June 1908 remains one of the great mysteries of the 20th century: millions of trees put down over an area of 2200 km2 without trace of a crater or meteorite fragments. Hundred years of failed searches have followed, resulting in as many flawed hypothesis which could not offer satisfactory explanations: meteorite, comet, UFO, etc. In the author's opinion, the cause is that the energy the explorers looked for was simply not there! The author's hypothesis is that a meteoroid encountered a gas pouch in the atmosphere, producing a devastating explosion, its effects being amplified by soil fluidization.

  11. Thermoregulation in juvenile red kangaroos (Macropus rufus) after pouch exit: higher metabolism and evaporative water requirements.

    2001-01-01

    The population dynamics of red kangaroos (Macropus rufus) in the Australian arid zone is tightly linked with environmental factors, which partly operate via the survival of juvenile animals. A crucial stage is the young-at-foot (YAF) stage when kangaroos permanently exit the pouch. We have examined the thermal biology of YAF red kangaroos during ages from permanent pouch exit until weaning. Over a wide range of environmental temperatures (ambient temperature [T(a)] -5 degrees to 45 degrees C), YAF red kangaroos had a mass-specific metabolism that was generally twice that of adults, considerably higher than would be expected for an adult marsupial of their body size. The total energy requirements of YAF red kangaroos were 60%-70% of those of adult females, which were three times their size. Over the same range in T(a), YAF red kangaroos also had total evaporative water losses equal to those of adult females. At the highest T(a) (45 degrees C), differences were noted in patterns of dry heat loss (dry conductance) between YAF red kangaroos and adult females, which may partially explain the relatively high levels of evaporative cooling by YAF. By weaning age, young kangaroos showed little change in their basal energy and water requirements (at T(a) 25 degrees C) but did show reduced mass-specific costs in terms of energy and water use at extremes of T(a) (-5 degrees and 45 degrees C, respectively). In their arid environment, typified by unpredictable rainfall and extremes of T(a), young red kangaroos may need to remain close to water points, which, in turn, may restrict their ability to find the high-quality forage needed to meet their high energy demands.

    Full Text Available Objective methods for examination of pouch function are warranted for a better understanding of the functional result and treatment of dysfunction. The objective of this study was to evaluate the results of scintigraphic intestinal transit time and defaecography compared to the results of pouch function, mucosal condition and a questionnaire on quality of life (QoL. This cross-sectional study included 21 patients. Scintigraphic transit time and defaecography was determined with the use of Tc-99m. Pouch function was assessed by number of bowel movements, pouch volume, and continence. Pouch mucosal condition was evaluated by endoscopy and histology. Median transit time was 189 min (105–365. Median ejection fraction at defaecography (EF was 49% (3–77 and 62% (17–98 after first and second defecation. Median pouch volume was 223 mL (100–360. A median daily stool frequency of nine (4–25 was reported and three (14% patients suffered from daytime incontinence. No patients had symptomatic or endoscopic pouchitis; however, the histology showed unspecific inflammation in 19 (90% patients. There was no correlation between transit time, evacuation fraction (EF and pouch function in univariate analysis. However, we found a high body mass index (BMI and a low bowel movement frequency to be associated with a longer transit time by multivariate analysis. Scintigraphic determination of transit time and defaecography are feasible methods in patients with ileal pouch anal anastomosis, but the clinical relevance is yet doubtful.

    2010-01-01

    Full Text Available Total restorative proctocolectomy with ileal pouch-anal anastomosis (RP/IPAA has become the standard of care for the surgical treatment of ulcerative colitis. Despite its correlation with an excellent quality of life and favorable long-term outcomes, RP/IPAA has been associated with several complications. Prolapse of the ileoanal pouch is a rare and debilitating complication that should be considered in the differential diagnosis of pouch failure. Limited data exist regarding the prevalence and treatment of pouch prolapse. We present the case of a recurrent J-pouch prolapse treated with a novel minimally invasive “salvage” approach involving a robotic-assisted laparoscopic rectopexy with mesh.

    2012-02-03

    PURPOSE: Although functional results after ileal pouch-anal anastomosis are excellent, imperfections of function do occur. In this setting, quality-of-life assessment is an invaluable tool in determining overall therapeutic efficacy. We evaluated the impact of dietary restrictions, preoperative diagnosis (ulcerative colitis vs. familial adenomatous polyposis), and pregnancy (after pouch insertion) on quality of life. METHODS: After ethical approval, 64 patients were reviewed (mean age, 31 (range, 15-54) years). Long-term quality of life in patients after ileal pouch-anal anastomosis was assessed using the Cleveland Global Quality of Life instrument or Fazio score. The Cleveland Global Quality of Life score is a novel quality-of-life instrument specifically designed for patients with ileal pouches. Stool frequency and continence were recorded to establish the functional status of this group. RESULTS: Sixty-one patients (95.3 percent) complained of some form of dietary restriction and adopted a fixed dietary regimen. All such patients felt that a breach of this regimen would impinge significantly on their quality of life. Late eating and alcohol were associated with diarrhea, whereas smoking was not. Constipation was infrequently reported. The mean Cleveland Global Quality of Life score of patients with ulcerative colitis (0.81 +\\/- 0.13) was greater than that of patients with ulcerative colitis and a background of pouchitis (0.78 +\\/- 0.16; P = 0.042). Whereas postoperative stool frequency in patients with familial adenomatous polyposis was always higher than the preoperative level (4 vs. 2 movements per day; P = 0.04), the Cleveland Global Quality of Life score of this group was lower than that of ulcerative colitis patients (0.77 vs. 0.81; P = 0.047). The Cleveland Global Quality of Life score of females who had had pregnancies after pouch formation was 0.70, significantly lower (P = 0.039) than that of ulcerative colitis patients, although pouch function was

    Directory of Open Access Journals (Sweden)

    Gianluca Pellino

    2017-01-01

    Full Text Available Background: Few cases of pouch-related cancers have been reported in ulcerative colitis (UC, and squamous cell carcinoma (SCC is very rare. Method: A systematic review of the literature was performed to identify all unequivocal cases of pouch-related SCC in UC patients. Results: Eight cases of SCC developing after ileal pouch-anal anastomosis (IPAA have been observed since 1978. Two arose from the pouch mucosa and 6 from below. The pooled cumulative incidence of SCC is below 0.06% after IPAA. Many patients had neoplasia on the preoperative specimen, but squamous metaplasia of the pouch or anorectal mucosa may have an important role in SCC. These patients are rarely offered chemoradiation therapy and the outcome is poor. Selected patients with SCC located close to the pouch outlet can be treated with chemoradiation prior to consideration of surgery and salvage their pouch. A chemoradiation regimen is suggested to avoid pouch excision in these patients. Conclusions: SCC is rare after pouch surgery but associated with extremely poor survival. Very low SCC can be managed with chemoradiation treatment, preserving the pouch and avoiding surgery, even in older patients. The role of pouch metaplasia, surveillance frequency, and treatment modalities after IPAA need further studying.

    Studies comparing the outcome of ileal pouch-anal anastomosis (IPAA) in children and adults are scarce. This complicates decision-making in young patients. The aim of this study was to compare adverse events and pouch function between children and adults who underwent IPAA. This cross-sectional cohort study included all consecutive children (aged less than 18 years) and adults with a diagnosis of inflammatory bowel disease or familial adenomatous polyposis who underwent IPAA in a tertiary referral centre between 2000 and 2015. Adverse events were assessed by chart review, and pouch function by interview using a pouch function score (PFS). In total, 445 patients underwent IPAA: 41 children (median age 15 years) and 404 adults (median age 39 years), with a median follow-up of 22 (i.q.r. 8-68) months. Being overweight (P = 0·001), previous abdominal surgery (P = 0·018), open procedures (P children than adult patients. The occurrence of anastomotic leakage, surgical fistulas, chronic pouchitis and Crohn's of the pouch was not associated with paediatric age at surgery, nor was pouch failure. The development of anastomotic strictures was associated with having IPAA surgery during childhood (odds ratio 4·22, 95 per cent c.i. 1·13 to 15·77; P = 0·032). Pouch function at last follow-up was similar in the children and adult groups (median PFS 5·0 versus 6·0 respectively; P = 0·194). Long-term pouch failure rates and pouch function were similar in children and adults. There is no need for a more cautious attitude to use of IPAA in children based on concerns about poor outcome. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    In the vast majority of cases the terminal ileum is used for incontinent or continent bladder substitution. However, in irradiated patients the use of ileum segments or the ileocecal reservoir is associated with an increased risk of early and late complications. For this reason these patients should be treated with a transverse conduit or pouch as the method of choice if urinary diversion is indicated. The superior outcome of this high urinary diversion is due to the use of non-irradiated segments of the colon and ureter. The lack of experience in large bowel surgery by today's urologists should be compensated by training or referral of these high risk patients to a specialized center.

    The microorganisms associated with mandibular third molar pericoronitis were investigated using direct microscopy and anaerobic culture method. The pericoronal pouch was sampled with paper points in A) 8 patients without mandibular third molar pericoronitis and B) 6 patients with mandibular third molar pericoronitis. Under the microscope, the microflora was found to be a complex mixture comprising gram-positive and gram-negative cocci, rods and filaments (including fusiform and curved rods), motile rods and spirochetes. Significantly higher proportions of motile, gram-negative rods were found in group B than in group A. The predominant cultivable microflora of 9 samples: A (4) and B (5) comprised several species of facultative and obligate anaerobic bacteria, namely Peptostreptococcus, Streptococcus, Actinomyces, Eubacterium, Propionibacterium, Veillonella, Porphyromonas, Prevotella, Bacteriodes, Fusobacterium, Campylobacter, Staphylococcus, Stomatococcus, Lactobacillus, Neisseria, Capnocytophaga, Haemophilus, Selenomonas and Centipeda species. The microflora in pericoronitis appeared similar to that of diseased periodontal pockets.

    The purpose of this study was to compare experiences and concerns about pouch seal leakage between persons with ostomies residing in North America (Canada and the United States) and Europe (United Kingdom, Netherlands, Sweden, Germany, Belgium, France, and Italy). Differences in reported pouch wear time and accessories used between the 2 groups were also examined. Secondary analysis of data from a cross-sectional study (Ostomy Life Study). Responses from persons residing in European countries (n = 1939) were compared with responses of 1387 individuals residing in North American countries. Persons with an ostomy completed a questionnaire that focused on 4 topics related to the daily use of an ostomy pouching system (pouch seal leakage, ballooning, appearance of pouching system such as color and size of the pouch and whether it is discrete under clothing, and coupling failure of 2-piece pouching systems). Pouch seal leakage was defined as stomal effluent seeping between the skin and the wafer of the ostomy pouching system. Statistical analysis was performed using a proportional odds model including various variable effects. Special attention was given to frequency of pouch seal leakage occurrences. All tests were 2-sided; P values ≤.05 were deemed statistically significant. Participants living in the North American countries indicated they were more likely to experience leakage from the ostomy (odds ratio = 2.610, 95% CI 2.187-3.115; P < .0001). Findings also indicated they were more likely to worry about pouch seal leakage than those in the European countries' data set (odds ratio = 2.722, 95% CI 2.283-3.246; P < .0001). Participants residing in the North American countries had significantly longer wear times than those participants in the European countries (P < .0001, χ test). The use of accessories was associated with a longer pouching system wear time. Study results suggest that participants from the North American countries indicated significantly more

    2001-01-01

    Full Text Available A 32-year-old man with ulcerative colitis had a colectomy for toxic colitis. Later, a rectal mucosectomy was performed along with the creation of a pelvic pouch. In 1998, approximately 10 years after this staged restorative proctocolectomy was completed, endoscopic examination of the pelvic pouch detected a small mucosal polypoid mass lesion. Although the lesion had the macroscopic appearance of an inflammatory polyp, microscopic sections of the resected lesion revealed dysplastic changes. Endoscopic polypectomy was performed to remove the lesion, and further histological surveillance examinations of the pelvic pouch have not detected additional dysplastic mucosal changes.

    Research into cancer prevention seeks to identify the preventable causes of cancer, and to reduce cancer incidence by effective implementation of preventative strategies in target populations. In this study, 30 male golden Syrian hamsters were divided into three equal groups; the right buccal pouches of the hamster rats in group one were painted with 0.5% solution of 7,12-dimethylbenz[a]anthracene (DMBA), three times a week, until sacrificed. The same pouches of group two were also painted with DMBA, but received an additional 10mg/daily Spirulina platensis extract, which was added to the soft diet supplements during the same period. The hamster rats in group three received neither DMBA nor S. platensis extract. They were painted with saline and served as control animals. Half the hamsters from each of the three groups were sacrificed by ether inhalation after 7 weeks, and the remaining half were sacrificed after 14 weeks. The required buccal pouches were surgically excised and prepared for regular H&E and argyrophilic proteins of the nuclear organizer regions (AgNOR) silver staining. AgNORs counting and statistical analysis were carried out. We observed moderate dysplastic changes extending into the midspinous layer in group one 7 weeks after DMBA painting, which reached to half the thickness of the hyperplastic epithelium after 14 weeks. However, in group two, mild dysplastic changes were observed after 7 weeks, which were restricted to the basilar and parabasilar layers of the epithelium after 14 weeks of treatment. AgNOR staining in group one produced AgNOR counts ranging from one to seven dots per nucleus, whereas the counts were one or two dots per nucleus in group two. The AgNOR mean number in groups one, two and three was (3.1+/-0.006, 1.3+/-0.003 and 1.2+/-0.003, respectively). Moreover, with one sample t-test, a significant difference was found in AgNOR mean number between groups one and two, groups one and three and between groups two and three (Phamster

    Clostridium difficile infection (CDI) of the ileal pouch following restorative proctocolectomy (RPC) is becoming increasingly recognized. We aimed to understand better (i) the associated risk factors, (ii) treatment practices and (iii) the pouch diversion and failure rate in patients who developed CDI of the pouch after RPC for ulcerative colitis (UC). Patients who tested positive for C. difficile of the pouch between 2007 and 2010 were included in the analysis. Data collected included patient demographics, time from RPC to documented CDI, the treatment of CDI and rate of excision of the pouch. Of 2785 patients recorded in the hospital CDI database, 15 had had an RPC with ileal pouch anal anastomosis. The median age was 44 years and the median interval from RPC to first documented episode of CDI was 3 years. Thirteen (81%) patients had had multiple episodes of pouchitis before and after CDI infection, and all were symptomatic at the time of testing for CDI. Within 30 days of the diagnosis of CDI, six (40%) patients were taking immunosuppressive medication, seven (47%) were taking a proton pump inhibitor and 12 (80%) had received antibiotics. Five patients required hospitalization for CDI and four had severe infections characterized by a serum creatinine more than 1.5 times baseline (n = 3) and a white cell count above 15 000 (n = 1). Six patients who underwent endoscopy had severe inflammation of the pouch including the presence of a pseudomembrane in one case. Ten patients were treated with metronidazole alone and five with vancomycin. Two patients had recurrent CDI of the pouch during a median follow-up period of 2.9 years and one had CDI refractory to medical management. This patient required diversion of the pouch with an ileostomy for refractory CDI but no patient required excision of the pouch. All 15 patients developing CDI of the pouch were successfully treated with antibiotics and only one required surgery in the form of an ileostomy. Colorectal

    Colonic J-pouch-anal anastomosis or colonic side-to-end anastomosis is the reconstruction of choice after low anterior resection. However, the mechanisms of defecation after both reconstruction forms are still speculative. Low anterior rectal resections were performed in 12 dogs with six colonic J-pouch-anal (pouch) and six coloanal side-to-end (SE) reconstructions. Four months postoperative stool frequency, intestinal transit time, and neorectal compliance were determined by radiography and barostat. Defecation mechanisms were evaluated radiographically during expulsion of artificial stool. One dog with pouch reconstruction could not be evaluated due to an anastomotic leak, while the others had uncomplicated course. Spontaneous stool frequency was significantly increased with both reconstruction methods (control 2.0+/-0.9, pouch 2.7+/-1.2, SE 3.3+/-0.9 day; ptime was significantly higher with pouch reconstruction due to storage of stool in the pouch and the descending colon compared to SE (control 760+/-82, pouch 592+/-97, SE 550+/-87 min; pevacuation is passive and independent from pouch motility. The functional principle of the colonic J-pouch is not its reservoir function but a delay of colonic motility.

    The impedance behavior of a 3.4 Ah pouch Lithium-Sulfur cell was extensively characterized using the electrochemical impedance spectroscopy (EIS) technique. EIS measurements were performed at various temperatures and over the entire state-of-charge (SOC) interval without applying a superimposed DC current. The obtained results have revealed a high dependency of the pouch cell’s impedance spectrum on the operating conditions. An equivalent electrical circuit was proposed to further analyze the...

  7. Early Transcriptomic Changes in the Ileal Pouch Provide Insight into the Molecular Pathogenesis of Pouchitis and Ulcerative Colitis

    Background: Ulcerative colitis (UC) only involves the colonic mucosa. Yet, nearly 50% of patients with UC who undergo total proctocolectomy with ileal pouch anal anastomosis develop UC-like inflammation of the ileal pouch (pouchitis). By contrast, patients with familial adenomatous polyposis (FAP) with ileal pouch anal anastomosis develop pouchitis far less frequently. We hypothesized that pathogenic events associated with the development of UC are recapitulated by colonic-metaplastic transcriptomic reprogramming of the UC pouch. Methods: We prospectively sampled pouch and prepouch ileum mucosal biopsies in patients with UC with ileal pouch anal anastomosis 4, 8, and 12 months after their pouch was in continuity. Mucosal samples were also obtained from patients with FAP. Transcriptional profiles of the UC and FAP pouch and prepouch ileum were investigated via RNA sequencing and compared with data from a previously published microarray study. Results: Unlike patients with FAP, subjects with UC exhibited a large set of differentially expressed genes between the pouch and prepouch ileum as early as 4 months after pouch functionalization. Functional pathway analysis of differentially expressed genes in the UC pouch revealed an enhanced state of immune/inflammatory response and extracellular matrix remodeling. Moreover, >70% of differentially expressed genes mapped to published inflammatory bowel diseases microarray data sets displayed directional changes consistent with active UC but not with Crohn's disease. Conclusions: The UC pouch, well before histologic inflammation, already displays a systems-level gain of colon-associated genes and loss of ileum-associated genes. Patients with UC exhibit a unique transcriptomic response to ileal pouch creation that can be observed well before disease and may in part explain their susceptibility to the development of pouchitis.

    Full Text Available This study presents the results of T. mentagrophytes inoculation in the cheek pouch of the hamster, an immunologically privileged site. Forty two animals were used: 21 inoculated with 10(6 fungi in the cheek pouch (group 1 and 21 inoculated initially with 10(6 fungi in the foot pad and 15 days later in the cheek pouch, with the same amount of fungi (group 2. Animals were sacrificed at 20 hours, 3, 7, 14, 30, 60, and 120 days; samples from inoculated cheek pouch, and foot pads submitted to the foot pad test (FPT, were collected. Independent of group and time of evolution of infection, animals did not develop delayed hypersensitivity evaluated through the FPT. The pre-inoculation of fungi in the foot pad did not change the morphology of lesions induced in the cheek pouch. Therefore, in animals of group 1 and 2, the introduction of the fungus in the cheek pouch resulted in focal lesion composed of a sterile acute inflammatory infiltrate, with abscess formation that evolved to a macrophagic reaction, and later to resolution even in the absence of immune response detectable by FPT. Our results indicate that in spite of the important role of the immune response in the spontaneous regression of dermatophytosis, other factors are also an integral part in the defense against this fungal infection.

    2015-12-01

    Viviparity (live birth) has evolved more than 150 times in vertebrates, and represents an excellent model system for studying the evolution of complex traits. There are at least 23 independent origins of viviparity in fishes, with syngnathid fishes (seahorses and pipefish) unique in exhibiting male pregnancy. Male seahorses and pipefish have evolved specialized brooding pouches that provide protection, gas exchange, osmoregulation, and limited nutrient provisioning to developing embryos. Pouch structures differ widely across the Syngnathidae, offering an ideal opportunity to study the evolution of reproductive complexity. However, the physiological and genetic changes facilitating male pregnancy are largely unknown. We used transcriptome profiling to examine pouch gene expression at successive gestational stages in a syngnathid with the most complex brood pouch morphology, the seahorse Hippocampus abdominalis. Using a unique time-calibrated RNA-seq data set including brood pouch at key stages of embryonic development, we identified transcriptional changes associated with brood pouch remodeling, nutrient and waste transport, gas exchange, osmoregulation, and immunological protection of developing embryos at conception, development and parturition. Key seahorse transcripts share homology with genes of reproductive function in pregnant mammals, reptiles, and other live-bearing fish, suggesting a common toolkit of genes regulating pregnancy in divergent evolutionary lineages. © The Author 2015.

  11. Recurrent Volvulus of an Ileal Pouch Requiring Repeat Pouchopexy: A Lesson Learnt

    Directory of Open Access Journals (Sweden)

    Pär Myrelid

    2014-01-01

    Full Text Available Introduction. Restorative surgery for ulcerative colitis with ileal pouch anal anastomosis (IPAA is frequently accompanied by complications. Volvulus of the ileal pouch is one of the most rarely reported late complications and to our knowledge no report exists on reoperative surgery for this condition. Case Report. A 58-year-old woman who previously had undergone restorative proctocolectomy due to ulcerative colitis with an IPAA presented with volvulus of the pouch. She was operated with a single row pouchopexy to the presacral fascia. Two months later she returned with a recurrent volvulus. At reoperation, the pouch was found to have become completely detached from the fascia. A new pexy was made by firmly anchoring the pouch with two rows of sutures to the presacral fascia as well as with sutures to the lateral pelvic walls. At follow-up after five months she was free of symptoms. Conclusion. This first report ever on reoperative surgery for volvulus of a pelvic pouch indicates that a single row pouchopexy might be insufficient for preventing retwisting. Several rows seem to be needed.

    The lesser pouched rat, Beamys hindei, is a small rodent that is patchily distributed in the Eastern Arc Mountains and coastal forests in East Africa. The ecology of this species and its current distribution in coastal forests is not well known. Therefore, we conducted a study in selected coastal forests to assess the current distribution of the species and to investigate the population ecology in terms of abundance fluctuations and demographic patterns. Assessments of the species distribution were conducted in 5 forests through trapping with Sherman live traps. Data on ecology were obtained from monthly capture-mark-recapture studies conducted for 5 consecutive nights per month in two 1 ha grids set in Zaraninge Forest over a 2-year period. The results indicate the presence of B. hindei in 3 forests where it was not previously recorded. The population abundance estimates ranged from 1 to 40 animals per month, with high numbers recorded during rainy seasons. Reproduction patterns and sex ratios did not differ between months. Survival estimates were not influenced by season, and recruitment was low, with growth rate estimates of 1 animal per month. These estimates suggest a stable population of B. hindei in Zaraninge Forest. Further studies are recommended to establish the home range, diet and burrowing behavior of the species in coastal forests in East Africa. © 2015 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    Although restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) substantially reduces the risk of colorectal cancer in patients with inflammatory bowel disease (IBD), subsequent pouch neoplasia can develop. There are few data on the incidence of and risk factors for neoplasia, so there is no consensus on the need for pouch surveillance. We aimed to determine the cumulative incidence of pouch neoplasia in patients with IBD and identify risk factors for developing pouch neoplasia. We searched the Dutch Pathology Registry (PALGA) to identify all patients with IBD and IPAA in The Netherlands from January 1991 to May 2012. We calculated the cumulative incidence of pouch neoplasia and performed a case-control study to identify risk factors. Demographic and clinical variables were analyzed with univariable and multivariable Cox regression analyses. We identified 1200 patients with IBD and IPAA; 25 (1.83%) developed pouch neoplasia, including 16 adenocarcinomas. Respective cumulative incidences at 5, 10, 15, and 20 years were 1.0%, 2.0%, 3.7%, and 6.9% for pouch neoplasia and 0.6%, 1.4%, 2.1%, and 3.3% for pouch carcinoma. A history of colorectal neoplasia was the only risk factor associated with pouch neoplasia. Hazard ratios were 3.76 (95% confidence interval, 1.39-10.19) for prior dysplasia and 24.69 (95% confidence interval, 9.61-63.42) for prior carcinoma. The incidence of pouch neoplasia in patients with IBD without a history of colorectal neoplasia is relatively low. Prior dysplasia or colon cancer is associated with an approximate 4- and 25-fold increase in risk, respectively, of developing pouch neoplasia. Copyright © 2014 AGA Institute.

    It is crucial to maintain temperature homogeneity in lithium ion batteries in order to prevent adverse voltage distributions and differential ageing within the cell. As such, the thermal behaviour of a large-format 20 Ah lithium iron phosphate pouch cell is investigated over a wide range of ambient temperatures and C rates during both charging and discharging. Whilst previous studies have only considered one surface, this article presents experimental results, which characterise both surfaces of the cell exposed to similar thermal media and boundary conditions, allowing for thermal gradients in-plane and perpendicular to the stack to be quantified. Temperature gradients, caused by self-heating, are found to increase with increasing C rate and decreasing temperature to such an extent that 13.4 ± 0.7% capacity can be extracted using a 10C discharge compared to a 0.5C discharge, both at -10 °C ambient temperature. The former condition causes an 18.8 ± 1.1 °C in plane gradient and a 19.7 ± 0.8 °C thermal gradient perpendicular to the stack, which results in large current density distributions and local state of charge differences within the cell. The implications of these thermal and electrical inhomogeneities on ageing and battery pack design for the automotive industry are discussed.

  4. Possible mechanisms for the venular constriction elicited by Ruscus extract on hamster cheek pouch.

    1994-07-01

    We investigated the influence of alpha-adrenoceptors blockers and calcium blockers on the effects of the venotonic agent Ruscus extract on the diameter of arterioles (ID 10-70 microns) and venules (ID 20-135 microns) of hamster cheek pouch microvasculature in vivo. For microcirculatory measurements, the preparations were placed under an intravital microscope coupled to a closed-circuit TV system. The TV monitor display was used to obtain arteriolar and venular internal diameter recordings (always at the same site) by an image shearing device. All drugs were applied topically. Ruscus extract was tested in different concentrations and in combination with prazosin (alpha 1-adrenoceptor antagonist), rauwolscine (alpha 2-adrenoceptor antagonist), or diltiazem (calcium blocker). Topical application of Ruscus extract elicited concentration-dependent responses in the studied vessels: arterioles remained unchanged in the concentration range tested, whereas venules remained unchanged or constricted depending on the concentration used. The observed venular constriction could be blocked by low concentrations (10(-9) M) of prazosin or diltiazem and by high concentrations (> 10(-6) M) of rauwolscine. Our results suggest that the venular constriction elicited by Ruscus extract in vivo, at the microcirculatory level, is mediated by calcium and by alpha-adrenoceptors and further support data previously reported on larger vessels and on patients with venous insufficiency.

    21st birthday celebrations are among the highest risks for alcohol use throughout emerging adulthood and celebrants often experience a range of alcohol-related consequences. The present research considered what happens when drinking games are paired with an already high-risk event (i.e., 21st birthday celebrations) and how drinking games compare with other contextual factors on 21st birthdays. Approximately four days after turning 21, 1124 college students (55% women) completed an online survey assessing alcohol use and related consequences experienced during their birthday celebrations. Participants were also asked whether drinking games and other contextual factors were associated with their celebrations. Overall, 18% of participants reported playing drinking games during their 21st birthday celebrations. These individuals reported consuming more alcohol, had higher estimated BACs, and experienced more negative consequences than those who did not play drinking games. The association between playing drinking games and alcohol use and negative consequences was stronger for men. The effect of drinking games on negative consequences was mediated through elevated BAC levels. Receiving bar specials, having drinks purchased, playing drinking games, and loud music were uniquely and significantly associated with all alcohol outcomes. Together, these results suggest that drinking games are part of a larger context of risk contributing to extreme drinking on 21st birthdays. Furthermore, these results will help to facilitate interventions that are more individually tailored to target specific contextual risks, behaviors, and events.

    During ontogeny, part of Rathke's pouch, a physiologically superior pouching of the stomodeal ectoderm, may remain, forming the usual anomaly known as Rathke's cleft cyst. More rarely, however, the entire pouch (i.e., the craniopharyngeal canal) remains, resulting in transsphenoidal meningoencephalocele. This study is aimed to provide a better understanding of the pathogenesis. We histologically evaluated the inferior protrusion of the putative hypophysial fossa in 35 embryonic and fetal heads, respectively (15 at 5-8 weeks and 20 at 12-16 weeks of gestation). In 3 of the 35 specimens, we observed a complete cleft originating from the adenohypophysis, passing through the sphenoid and connecting with the pharyngeal epithelium or pharyngobasilar fascia. In another 18 specimens, we observed a duct-like structure protruding from the fossa and ending in the sphenoid. The sellar protrusion contained vein-like structures and debris of red blood cells. The protrusion was located on the anterior or anterosuperior side of the notochord. No ossification center was observed around the sellar region of the embryos. Although ossification occurred in 12 of the 20 fetuses, nine of the latter showed no evidence of cleft or protrusion, indicating that the incidence of Rathke's pouch remnant was lower in the fetuses (11/20) than in the embryos (11/15). Rathke's pouch may be closed by ossification of the sphenoid, but increased cell proliferation and/or large amounts of degenerated veins may provide a structure resistant to the mechanical pressure caused by ossification.

  7. Bmp signaling mediates endoderm pouch morphogenesis by regulating Fgf signaling in zebrafish.

    The endodermal pouches are a series of reiterated structures that segment the pharyngeal arches and help pattern the vertebrate face. Multiple pathways regulate the complex process of endodermal development, including the Bone morphogenetic protein (Bmp) pathway. However, the role of Bmp signaling in pouch morphogenesis is poorly understood. Using genetic and chemical inhibitor approaches, we show that pouch morphogenesis requires Bmp signaling from 10-18 h post-fertilization, immediately following gastrulation. Blocking Bmp signaling during this window results in morphological defects to the pouches and craniofacial skeleton. Using genetic chimeras we show that Bmp signals directly to the endoderm for proper morphogenesis. Time-lapse imaging and analysis of reporter transgenics show that Bmp signaling is necessary for pouch outpocketing via the Fibroblast growth factor (Fgf) pathway. Double loss-of-function analyses demonstrate that Bmp and Fgf signaling interact synergistically in craniofacial development. Collectively, our analyses shed light on the tissue and signaling interactions that regulate development of the vertebrate face. © 2016. Published by The Company of Biologists Ltd.

    Full Text Available Pharyngeal endoderm is essential for and can reprogram development of the head skeleton. Here we investigate the roles of specific endodermal structures in regulating craniofacial development. We have isolated an integrinalpha5 mutant in zebrafish that has region-specific losses of facial cartilages derived from hyoid neural crest cells. In addition, the cranial muscles that normally attach to the affected cartilage region and their associated nerve are secondarily reduced in integrinalpha5- animals. Earlier in development, integrinalpha5 mutants also have specific defects in the formation of the first pouch, an outpocketing of the pharyngeal endoderm. By fate mapping, we show that the cartilage regions that are lost in integrinalpha5 mutants develop from neural crest cells directly adjacent to the first pouch in wild-type animals. Furthermore, we demonstrate that Integrinalpha5 functions in the endoderm to control pouch formation and cartilage development. Time-lapse recordings suggest that the first pouch promotes region-specific cartilage development by regulating the local compaction and survival of skeletogenic neural crest cells. Thus, our results reveal a hierarchy of tissue interactions, at the top of which is the first endodermal pouch, which locally coordinates the development of multiple tissues in a specific region of the vertebrate face. Lastly, we discuss the implications of a mosaic assembly of the facial skeleton for the evolution of ray-finned fish.

    An assessment is made of the possibilities of using geothermal energy and an aseptic retortable pouch in the food processing industry. The focus of the study is on the production of frozen broccoli in the Imperial Valley, California. Background information on the current status of the frozen food industry, the nature of geothermal energy as a potential substitute for conventional fossil fuels, and the engineering details of the retortable pouch process are covered. The analytical methodology by which the energy and process substitution were evaluated is described. A four-way comparison of the economics of the frozen product versus the pouched product and conventional fossil fuels versus geothermal energy was performed. A sensitivity analysis for the energy substitution was made and results are given. Results are summarized. (MCW)

    To compare the outcomes obtained in patients undergoing endoscopic stapling of pharyngeal pouches with single versus multiple rows of staples. A retrospective, 10-year review. Review of medical records in 38 patients who underwent endoscopic pharyngeal pouch repair. Patients who underwent stapling with multiple rows had a higher postoperative leak rate than patients who were stapled with a single row (36% vs 0%, P multiple rows also had a more prolonged length of stay and a slower return to both clear fluids and solid diet (P row of staples may be necessary to divide the common wall. However, in our series this is associated with a significantly increased risk of esophageal or pouch perforation. Care should be taken during the placement of multiple rows of staples.

    Full Text Available We conducted a retrospective chart review of robotic prostatectomies done by a single surgeon between 2003 and 2012. During that time period, we identified two patients within the year 2012, with ileal pouch-anal anastomosis (IPPA who also underwent robotic prostatectomies. The demographics and postoperative characteristics of the two patients were assessed. In both patients, prostatectomy, bilateral nerve sparing, and pelvic lymphadenectomy were successfully performed and the integrity of ileal pouch was maintained. There was a mean surgical time of 144.5 minutes, and an average estimated blood loss was 125 mL. Both patients were discharged on the second day postoperatively. In both patients there was a Gleason upgrade to 3 + 4, with negative margins, and preservation of fecal and urinary continence by their six-month followup. Owing to surgical modifications, these two surgeries represent the first successful robotic prostatectomies in patients with a J-pouch.

    Surgery for ulcerative colitis is a major and complex colorectal surgery. Laparoscopy benefits these patients with better outcomes in context of cosmesis, pain and early recovery, especially in young patients. For surgeons, it is a better tool for improving vision and magnification in deep cavities. This is not the simple extension of the laparoscopy training. Starting from preoperative preparation to post operative care there are wide variations as compared to open surgery. There are also many variations in steps of laparoscopic surgery. It involves left colon, right colon and rectal mobilisation, low division of rectum, pouch creation and anastomosis of pouch to rectum. Over many years after standardisation of this technique, it takes same operative time as open surgery at our centre. So we present our standardized technique of laparoscopic assisted restorative proctocolectomy and ileal pouch anal anastomosis (IPAA). PMID:26195886

    1981-07-01

    The utility of gamma-glutamyl transpeptidase (GGT) was explored as a histochemical marker for chemical carcinogenesis in hamster buccal pouch mucosa. One or both buccal pouches of 18 noninbred male Syrian golden hamsters were treated topically with 0.5% 7,12-dimethylbenz(a)anthracene (DMBA) in mineral oil over 16 weeks to produce numerous epithelial lesions at various stages of neoplastic development. Both buccal pouches of 4 control animals were similarly treated with mineral oil alone. GGT activity was not detectable in untreated pouches or pouches treated with mineral oil alone. With this technique, multiple discrete GGT-stained areas were visible in wholemounts prepared at 1 and 6 weeks after the final application of DMBA. The experimental results were consistent with the hypothesis that the early GGT-stained cell populations are preneoplastic in nature.

    The management of postoperative rectovaginal fistula (RVF) after rectal cancer surgery is difficult and requires reconstruction of the anastomotic site and fistula. Though various surgical procedures have been reported for the repair of RVFs, the results of surgical repair are often unsatisfactory, and failure of the initial repair leads to difficulty in the later operations. Furthermore, it has been reported that cases associated with local infection result in low success rates. We report a case of an 80-year-old woman with a recurrent colonic J pouch-vaginal fistula after anoabdominal rectal resection with partial internal sphincteric resection, who achieved a good outcome following a repair using a puborectal sling interposition combined with seton drainage. It may be a useful option for RVF management in repair of such pouch-vaginal fistula after coloanal anastomosis with intersphincteric resection.

  2. Ileoanal pouches: Comparison of CT, scintigraphy, and contrast enemas for diagnosing postsurgical complications

    Thoeni, R.F.; Fell, S.C.; Engelstad, B.; Schrock, T.B. (Univ. of California, San Francisco (USA))

    1990-01-01

    The value of CT of the pelvis, 111In-labeled leukocyte scintigraphy, and contrast enema (pouchography) for detecting postsurgical complications was assessed in 44 patients with total colectomy, rectal mucosectomy, and ileoanal pouches. Ileoanal pouches were created as reservoirs from an ileal loop that was anastomosed to the dentate line of the anus and stayed connected to the remainder of the ileum. This pouch preserves the normal defecatory pathway and eliminates disease-producing mucosa. A total of 57 sets of examinations revealed 22 cases of normal postoperative findings, 22 of pouchitis, 13 of abscess, and three of fistula. Overall sensitivity for detecting complications with pouchography was 60% (18 of 30 findings); with CT, 78% (28 of 36 findings); and with scintigraphy, 79% (23 of 29 findings). Pouchitis was best diagnosed by scintigraphy (sensitivity, 80%), followed by CT (sensitivity, 71%) and pouchography (sensitivity, 53%). Only CT correctly diagnosed all cases of abscess. Fistulas were frequently missed by all three methods. If tests were combined, the overall sensitivity rose to 93% for the combination CT/scintigraphy and to 86% for CT/pouchography, but did not improve for pouchography/scintigraphy (78%). For evaluation of complications in patients with ileoanal pouches, CT should be the initial test. If an abscess is found, no further tests are needed. If CT findings are negative, a scintigram should be obtained. Our data did not establish a clear role for pouchography.

  3. Histology of the terminal end of the distal rectal pouch and fistula region in anorectal malformations.

    Until recently, surgeons have been posed with a dilemma---whether or not they should preserve the terminal end of the distal rectal pouch and the fistula region in anorectal malformations (ARMs). A detailed histological study of this region was conducted to establish a consensus for preserving or excising this region for reconstruction of ARMs. Histopathological examination using haematoxylin and eosin-stained sections of the terminal portion of the distal rectal pouch and proximal portion of the rectourogenital or rectoperineal connection was performed in 60 cases of high, intermediate and low ARMs. Distorted internal sphincter was present in 93.3% of high, 90% of intermediate and 100% of low ARMs. The proximal fistula region was lined by transitional epithelium in 50% of cases, and anal glands were present in 83.3% and anal crypts in 68.3% of cases. The rectal pouch in the region of the internal sphincter and fistula was aganglionic in all cases. This study shows that the terminal end of the distal rectal pouch and proximal fistula region possess distorted anal features with aganglionosis, and contradicts the recommendation that this region should be reconstructed in patients with malformations.

    Retort Pouch had become a choice to preserve foods nowadays, besides the used of the can. Both had their own advantages, and Retort Pouch became more popular for the reason of cheaper and easier to recycle. General Method usually used to estimate the lethality of commercial heat sterilization process. Lethality value wa s used for evaluating the efficacy of the thermal process. This study aimed to find whether different layers of pouch materials affect the lethality value and to find differences lethality in two types of multilayer retort pouch, PET/Aluminum Foil/Nylon/RCPP and PET/Nylon/Modified Aluminum/CPP. The result showed that the different layer arrangement was resulted different Sterilization Value (SV). PET/Nylon/Modified Aluminum/CPP had better heat penetration, implied by the higher value of lethality. PET/Nylon/Modified Aluminum/CPP had the lethality value of 6,24 minutes, whereas the lethality value of PET/Aluminum Foil/Nylon/RCPP was 3,54 minutes.

    Low rectal tumors are often treated with sphincter-preserving resection followed by coloanal anastomosis. The purpose of this study was to compare the short-term complications following straight coloanal anastomosis vs colonic J-pouch anal anastomosis. Patients were identified who underwent proctectomy for rectal neoplasia followed by coloanal anastomosis in the 2008 to 2013 American College of Surgeons National Surgical Quality Improvement Program database. Demographic characteristics and 30-day postoperative complications were compared between groups. A national sample was extracted from the American College of Surgeons National Surgical Quality Improvement Project database. Inpatients following proctectomy and coloanal anastomosis for rectal cancer were selected. Demographic characteristics and 30-day postoperative complications were compared between the 2 groups. One thousand three hundred seventy patients were included, 624 in the straight anastomosis group and 746 in the colonic J-pouch group. Preoperative characteristics were similar between groups, with the exception of preoperative radiation therapy (straight anastomosis 35% vs colonic J-pouch 48%, p = 0.0004). Univariate analysis demonstrated that deep surgical site infection (3.7% vs 1.4%, p = 0.01), septic shock (2.25% vs 0.8%, p = 0.04), and return to the operating room (8.8% vs 5.0%, p = 0.0006) were more frequent in the straight anastomosis group vs the colonic J-pouch group. Major complications were also higher (23% vs 14%, p = 0.0001) and length of stay was longer in the straight anastomosis group vs the colonic J-pouch group (8.9 days vs 8.1 days, p = 0.02). After adjusting for covariates, major complications were less following colonic J-pouch vs straight anastomosis (OR, 0.57; CI, 0.38-0.84; p = 0.005). Subgroup analysis of patients who received preoperative radiation therapy demonstrated no difference in major complications between groups. This study had those limitations inherent to a

    Lan, Nan; Ashburn, Jean; Shen, Bo

    2017-08-01

    Background:Clostridium difficile infection (CDI) in patients with ileal pouch-anal anastomosis (IPAA) has been increasingly recognized. The aim of this study was to evaluate the outcome of fecal microbiota transplantation (FMT) in patients with pouch and CDI. Methods: All consecutive patients that underwent FMT for CDI from 2012 to 2016 were extracted from our IRB-approved, prospectively maintained Registry of Pouch Disorders. The primary outcome was negative stool tests for Clostridium difficile after FMT and the secondary outcomes were symptomatic and endoscopic responses. Results: A total of 13 patients were included in this study, with 10 being Caucasian males (76.9%). All patients had underlying ulcerative colitis for J pouch surgery. After a mean of 2.8±0.8 courses of antibiotic treatments was given and failed, 22 sessions of FMT were administered with an average of 1.7±1.1 sessions each. Within the 22 sessions, 16 were given via pouchoscopy, 4 via esophagogastroduodenoscopy and 2 via enemas. All patients tested negative on C. difficile polymerase chain reaction (PCR) after the initial FMT with a total of 7/12 (58.3%) documented patients showed symptomatic improvements and 3/11 (27.3%) patients showed endoscopic improvement according to the modified Pouchitis Disease Activity Index. During the follow-up of 1.2±1.1 years, there were a total of five patients (38.5%) that had recurrence after the successful initial treatment and four of them were successfully treated again with FMT. Conclusions: FMT appeared to be effective in eradication of CDI in patients with ileal pouches. However, FMT had a modest impact on endoscopic inflammation and recurrence after FMT and recurrence was common.

    1992-03-01

    We reported a 60-year-old woman with tricuspid pouch associated with ventricular septal defect and subsequent left ventricular-right atrial communication. Preoperative angiographic findings suggested the presence of membranous septal aneurysm, ventricular and atrial septal defects, and tricuspid insufficiency. However, at operation, besides perimembranous inlet type ventricular septal defect, a pouch, 1.5 cm in diameter was found in the adjacent part to the septal leaflet within the anterior one of the tricuspid valve. The ventricular septal defect was closed with a patch. From these findings, it is speculated that the tricuspid pouch was formed by the effect of jet stream through the ventricular septal defect.

    Full Text Available Background: The gold standard of the management of rectal cancer in the middle and lower parts is low anterior resection with coloanal anastomosis. About 50% of the patients undergoing this procedure might experience some complications because of the low capacity of the neorectum. The aim of this study was to evaluate ileal J-pouch interposition as a neorectum between the anal canal and the remaining colon in comparison to coloanal anastomosis and transverse coloplasty. Methods: Twelve dogs, weighing 23-27 kg, were divided into three groups. After laparotomy, the volume of the primary rectum was measured so that it could be compared with that of the neorectum at the end of the study. After rectal resection in Group A, the colon was directly anastomosed to the anus. In Group B, a 5-cm longitudinal incision was made 2 cm proximal to the anastomosis and was sutured transversely (coloplasty. In Group C, a 5-cm ileal J-pouch was interposed between the colon and anus. After 8 weeks, the neorectum was evaluated for volume, radiology, and pathology. Results: All the samples were alive until the end of the study. The healing of the anastomotic lines was acceptable (pathologically in all.

    2011-01-01

    INTRODUCTION: Light-to-moderate alcohol drinking is associated with a decreased risk of ischaemic heart disease (IHD). However, drinking heavily and in binges has been suggested to increase IHD risk. This complexity makes the issue of binge drinking within the light-to-moderate alcohol range......-to-moderate drinkers (defined ≤21 and ≤14 drinks/week for men and women, respectively). In the entire study population, we investigated the association between drinking frequency, separately and combined with total weekly alcohol intake, and risk of IHD and all-cause mortality. RESULTS: 1136 individuals developed IHD.......54-1.76). For women drinking 5-6 days/week, the risk of IHD was lower than for women drinking 1-2 days/week (HR 0.54, 95% CI 0.32-0.90). We did not observe any patterns when looking at combinations of total weekly alcohol intake and drinking frequency. CONCLUSIONS: Among light-to-moderate alcohol drinkers, binge...

    An 84-year-old male was admitted to a local clinic suffering from general fatigue with associated anemia, and therefore was referred to our hospital. His medical history included a proximal gastrectomy with the formation of a jejunal pouch as a reconstructive treatment for early upper gastric cancer at 78 years of age (6 years prior). A type 2 tumor located in the jejunal pouch almost completely surrounded by small intestinal mucosa was demonstrated by gastrointestinal endoscopy. The biopsy specimens showed a moderately differentiated tubular adenocarcinoma. Computed tomography showed no lymphadenopathy or hepatic metastases. A resection of the residual stomach and jejunal pouch was performed. Based on the histological findings from the resected specimen, the tumor was considered to be primary adenocarcinoma in the jejunal pouch. The postoperative course was uneventful, and the patient has shown no evidence of any recurrence during the 6-year period after the most recent surgery.

    Restorative proctocolectomy is a current gold standard procedure for patients who require a colectomy for ulcerative colitis. The incidence of ileal pouch neoplasia is low. The aims of this study were to assess the prevalence of neoplasia in ileal pouch and investigate the risk factors for ileal pouch neoplasia. A total of 276 patients who underwent restorative proctocolectomy for ulcerative colitis between 1984 and 2009 were analyzed. Results of histological examinations of both original specimen and biopsies from the J-pouch taken during routine pouch endoscopy were evaluated. Patients' records were analyzed for ulcerative colitis duration, the time from pouch creation to pouch neoplasia, presence of pouchitis, as well as the concurrent primary sclerosing cholangitis. Analyzing the original specimen of large bowel, fifty-six lesions of low-grade dysplasia, twenty-five high-grade dysplasia, and five adenocarcinoma were revealed. All patients with dysplasia (n = 8) or adenocarcinoma (n = 1) of the J-pouch were positive for dysplasia in the original specimen. Duration of ulcerative colitis before surgery and duration time following restorative proctocolectomy were found as risk factors for J-pouch neoplasia with a significant difference (p = 0.01 and p = 0.0003, respectively). Patients with pouch neoplasia developed significantly more severe pouchitis (p = 0.00001). Neoplasia of the J-pouch is rare. Patients with neoplasia in the original specimen are more susceptible to develop neoplasia in the J-pouch. Precise follow-up in patients with neoplasia lesions in the original specimen should be recommended. Moreover, in patients with risk factors, the exact surveillance pouch endoscopy should be recommended.

    Little information exists on the use of continent urinary reservoirs in patients with previous pelvic irradiation. We report the use of the Indiana pouch urinary reservoir in ten women with a history of pelvic irradiation for cervical cancer, of whom eight underwent a total pelvic exenteration for recurrent pelvic tumor and two had diversion for radiation-induced vesicovaginal fistula. All ten women achieved daytime continence, with a median time between catheterizations of 4.5 hours and a median pouch capacity of 500 mL. There was no evidence of leakage from the reservoir or significant ureteral reflux or obstruction on postoperative radiographic evaluation. No patient has required reoperation or had significant postoperative complications with the technique described.

    Necrosis of the pouch containing the generator, due to non-traumatic breakage of the batteries, was observed in a patient with a permanent pacemaker, followed by rapid ingravescence. The cause of this complication is discussed. Chemical inflammation was noted soon after the pacemaker ceased to function. Initially this was similar to the not uncommon bacterial inflammation noted in such patients. Here, of course, the pacemaker usually continues to work, and its replacement is optional, whereas in the reported case is an emergency matter. In situations where tissue distress in the pouch is accompanied by inflammation, therefore, thought should be given to the possibility that, even if the batteries are still working, the cause may be chemical or electrochemical rather than septic, and than sudden breakdown of the generator may be expected.

    Chlorophyllin, a water soluble semi-synthetic food-grade derivative is reported to exhibit a wide range of beneficial health effects. We investigated the effect of chlorophyllin supplementation on Wnt/β-catenin and vascular endothelial growth factor (VEGF) signaling in the 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis model. Hamsters were divided into 4 groups. The right buccal pouches of group 1 and 2 hamsters were painted with 0.5 % DMBA for 14 weeks. Group 2 animals received in addition chlorophyllin (4 mg/kg bw) in the diet. Group 3 animals received chlorophyllin alone and group 4 animals served as control. mRNA and protein expression of components of Wnt, VEGF, and PI3K/Akt signaling pathways were analyzed by RT-PCR and Western blot analysis. Dietary chlorophyllin administration suppressed the development of HBP carcinomas by altering the expression of several components of the Wnt/β-catenin signaling pathway. This was associated with inhibition of angiogenesis as evidenced by decreased expression of the proangiogenic factors HIF-1α, VEGF, and VEGFR2. Chlorophyllin administration also downregulated the expression of histone deacetylases involved in epigenetic regulation of tumor angiogenesis. Dietary chlorophyllin that abrogates Wnt/β-catenin and VEGF signaling by targeting a multitude of key signaling molecules is an attractive candidate for preventing tumor progression.

    Surgery for ileal pouch-anal anastomosis (IPAA) has evolved over time, especially since the introduction of laparoscopy. The aim of this retrospective study was to report the impact of surgical evolution on outcome over a period of 25 years. All patients who had IPAA surgery for ulcerative colitis from 1990 to 2015 at the University Hospitals of Leuven were included. Patients were divided into three period arms (period A 1990-1999; period B 2000-2009; period C 2010-2015). The main outcome measure was anastomotic leakage. A total of 335 patients (58.8% male) with a median age of 39 years (interquartile range 32-49 years) at surgery were included. Median follow-up was 5 years (interquartile range 2-10 years). Overall anastomotic leakage (grades A-C) was 14.9%. A significant decrease in leakage rate was observed over time (from 21.4% in period A to 12.1% in period B to 10.0% in period C; P = 0.04). The defunctioning ileostomy rate at the time of pouch construction decreased from 91.7% (period A) to 40.3% (period B) to 11.1% (period C) (P < 0.001). We observed an increase in the use of laparoscopy (23.9% in period A vs 72.6% in period B, vs 84.4% in period C; P = 0.001) and a shift to a modified two-stage procedure (4.1% in period A, vs 66.7% in period C; P < 0.0001). In a monocentric study with some of the data retrieved retrospectively it was not possible to account for the impact of preoperative nutritional status (weight loss, serum albumin level) or disease burden. Other outcome factors were not measured, for example sexual function and fecundity. A higher rate of laparoscopic IPAA surgery, together with a shift towards modified two-stage procedures, was associated with a lower leakage rate despite a reduction in the use of defunctioning ileostomy.

    This study examined the effects of chlorhexidine (CHD) on the clinical appearance, morphology, and in vitro permeability of hamster cheek pouch mucosa. The cheek pouches were treated daily for 3 weeks with topical applications of saline, 0.2% CHD, or 2.0% CHD. Treatment with 2.0% CHD resulted in the formation of discrete white lesions in every animal in the group, whereas no changes were identified in any animal treated with 0.2% CHD or saline. Upon microscopic examination it was determined that treatment with 2.0% CHD resulted in a statistically significant increase in epithelial thickness, when compared to the other groups, and the lesions were found to consist of hyperplastic areas of epithelium with associated inflammatory cell accumulations. Daily treatments with 2.0% CHD, 0.2% CHD or saline had no effect on the very low permeability of cheek pouch mucosa to /sup 14/C-CHD. However, treatment with 2.0% CHD resulted in decreased permeability to /sup 3/H/sub 2/O when compared to the other groups. Treatment with 2.0% CHD also resulted in a thickened permeability barrier, as determined using a tracer, horseradish peroxidase. It is concluded that topical applications of 0.2% T CHD have no detectable effect on cheek-pouch mucosa while applications of 2.0% CHD result in hyperplasia and a decrease in mucosal permeability. Results suggest that CHD should be used with caution clinically and at a concentration of 0.2% or less.

    Methicillin-resistant Staphylococcus aureus (MRSA) is recognized as a cause of nosocomial infections in both human and veterinary medicine. Studies that examine the nasopharynx and guttural pouches of the horse as carriage sites for MRSA have not been reported. MRSA colonizes the nasopharynx and guttural pouch of horses. To determine the prevalence of MRSA in equine nasopharyngeal wash (NPW) and guttural pouch lavage (GPL) samples in a field population of horses. One hundred seventy-eight samples (123 NPW and 55 GPL) from 108 horses. Prospective study. Samples were collected from a convenience population of clinically ill horses with suspected Streptococcus equi subsp. equi (S. equi) infection, horses convalescing from a known S. equi infection, and asymptomatic horses undergoing S. equi screening. Samples were submitted for S. aureus aerobic bacterial culture with mannitol salt broth and two selective agars (cefoxitin CHROMagar as the PBP2a inducer and mannitol salt agar with oxacillin). Biochemical identification of Staphylococcus species and pulsed-field gel electrophoresis (PFGE), to determine clonal relationships between isolates, were performed. Methicillin-resistant Staphylococcus (MRS) was isolated from the nasopharynx of 7/108 (4%) horses. Three horses had MRSA (2.7%), and 4 had MR-Staphylococcus pseudintermedius (MRSP). MRSA was isolated from horses on the same farm. PFGE revealed the 3 MRSA as USA 500 strains. Sampling the nasopharynx and guttural pouch of community-based horses revealed a similarly low prevalence rate of MRSA as other studies sampling the nares of community-based horses. More study is required to determine the need for sampling multiple anatomic sites when screening horses for MRSA. Copyright © 2017 The Authors.

    The univentricular heart after the Fontan operation may have a blind pouch formed by the pulmonary stump or rudimentary ventricle according to the anatomy before surgery. Thrombosis in an intracardiac blind pouch of patients with a univentricular heart is a hazardous complication. Because only a few reports have described this complication, the authors evaluated the clinical significance of thrombosis in an intracardiac blind pouch of a univentricular heart. They performed a retrospective review of medical records from August 1986 to December 2007. Four patients were confirmed as having thrombosis in a pulmonary artery stump and one patient as having thrombosis in a rudimentary ventricle shown by cardiac computed tomography (CT). This represents 1.85% (5/271) of patients with ongoing regular follow-up evaluation after the Fontan operation. The median age at diagnosis was 14.2 years. Two of the five patients were taking aspirin and one patient was taking warfarin when they were identified for the development of thrombosis. None of the patients demonstrated thrombosis in the Fontan tract or venous side of the circulation. Brain magnetic resonance imaging (MRI) showed that three patients had cerebral infarction and one patient had suggestive old ischemia. Three patients with thrombus in the pulmonary stump underwent pulmonary artery stump thrombectomy and pulmonary valve obliteration. One patient with thrombus in the rudimentary ventricle underwent ventricular septal defect (VSD) closure with thrombectomy. Thrombus in a blind pouch could cause systemic thromboembolism despite little blood communication. Therefore, surgical modification of the pulmonary stump and VSD closure of the rudimentary ventricle are required to reduce the risk of later thrombus formation. Clinicians should not overlook the possibility of thrombus in a ligated pulmonary artery stump or a rudimentary ventricle after the Fontan operation, which may increase the risk of embolic stroke for patients

    OBJECTIVE: To determine the dental hazards associated with sports supplement drinks by investigating the chemicophysical properties of eight brands of sports drinks. METHODS: The pH and titratable acidity against 0.1 M NaOH was measured. Calcium, phosphate, and fluoride concentrations and viscosities of Carbolode, Gatorade, High Five, Isostar, Lucozade Sport Lemon, Lucozade Sport Orange, Maxim, and PSP22 were determined. RESULTS: The pH values of the drinks ranged from 4.46 (Maxim) to 2.38 (Isostar) and therefore were below the critical pH value (5.5) for enamel demineralisation. Both Lucozade varieties had high titratable acidities (16.30 ml 0.1M NaOH to neutrality) with Gatorade, High Five, and Isostar displaying intermediate titratable acidity, although Isostar had 74.5 ppm calcium and 63.6 ppm phosphate. The fluoride concentration of all drinks was low, and none of the drinks was particularly viscous (range 3.1-1.4 mPa.s). CONCLUSIONS: The chemicophysical analyses indicate that all the sports drinks in this study have erosive potential. However, drinks with higher pH, lower titratable acidity, and higher concentrations of calcium, phosphate, and fluoride will reduce this erosive potential. Images Figure 1 Figure 2 PMID:9132205

    Paper substrate, especially circular filter paper placed inside a Petri dish, has long been used for the plant seed toxicity test (PSTT). Although this method is simple and inexpensive, recent evidence indicates that it gives results that are significantly different from those obtained using a method that does not involve paper, especially when testing metal cations. The study compared PSTT using three methods: filter paper, Growth Pouch-TM, and seed tray. The Growth Pouch-TM is a commercially available device. The seed tray is a newly designed plastic receptacle placed inside a Petri dish. The results of the Growth Pouch-TM method showed no toxic effects on rice for Ag up to 40 mg L-1 and Cd up to 20 mg L-1. Using the seed tray method, IC50 (50% inhibitory effect concentration) values were 0.55 and 1.4 mg L-1 for Ag and Cd, respectively. Although results of filter paper and seed tray methods were nearly identical for NaF, Cr(VI), and phenol, the toxicities of cations Ag and Cd were reduced by using the filter paper method; IC50 values were 22 and 18 mg L-1, respectively. The results clearly indicate that paper substrate is not advisable for PSTT.

    Full Text Available A gross morphological study of the brain of the African giant pouched rat (Cricetomys gambianus Waterhouse, 1840 was undertaken in order to document its normal features and assess the structure-function paradigm. The study was conducted by direct observation of 29 adult African giant pouched rats’ brains. In the telencephalon, the cerebral cortex was devoid of prominent gyri and sulci, but the large olfactory bulb and tract relaying impulses to the olfactory cortex were very prominent. The large size of the olfactory bulb correlated with the established sharp olfactory acuity of the rodent. In the mesencephalic tectum, the caudal colliculi were bigger than the rostral colliculi, indicating a more acute sense of hearing than sight. In the metencephalon, the cerebellar vermis, the flocculus and the paraflocculus were highly coiled and, thus, well developed. The myelencephalon revealed a better organised ventral surface than dorsal surface; the cuneate fascicle, the intermediate sulcus and the lateral sulcus were not evident on the dorsal surface, but there were clearly visible pyramids and olivary prominence on the ventral surface. In conclusion, the highly coiled cerebellar vermis, flocculus and paraflocculus, as well as the conspicuous pyramids and olivary prominence are indicative of a good motor coordination and balance in the African giant pouched rat.

    The importance of the duodenal passage and the need for pouch reconstruction after total gastrectomy are matters of controversy. Twenty consecutive patients with early gastric cancer were studied 20who underwent jejunal pouch double-tract (JPD) reconstruction after total gastrectomy. Nutritional variables were examined for > or =10 years postoperatively. The mean operation time was 204 minutes. There was no anastomotic leakage and no hospital mortality. Anastomotic stenosis between the esophagus and a jejunal pouch developed in 2 patients (10%), and reflux esophagitis was observed in 4 (20%). Symptoms were controlled by conserva tive treatment within 3 years after surgery. Body mass indices in all patients were significantly decreased from 1 month (p or =60 years and <60 years, respectively. The body weight decreases from 3 (p<0.05) to 6 (p<0.01), and at 9 years (p<0.01) were significantly lower before 60 years of age than after. JPD reconstruction facilitates long-term recovery of body weight after total gastrectomy and should be considered before the aged of 60.

    2013-01-01

    Full Text Available This study includes analysis of encapsulation materials from lithium-ion pouch cells and water vapour transmission rate (WVTR measurements. WVTR measurements are performed on both fresh and environmentally stressed lithium-ion pouch cells. Capacity measurements are performed on both the fresh and the environmentally stressed battery cells to identify possible influences on electrochemical performance. Preparation of the battery cells prior to WVTR measurements includes opening of battery cells and extraction of electrode material, followed by resealing the encapsulations and adhesively mounting of gas couplings. A model describing the water diffusion through the thermal welds of the encapsulation are set up based on material analysis of the encapsulation material. Two WVTR equipments with different type of detectors are evaluated in this study. The results from the WVTR measurements show how important it is to perform this type of studies in dry environment and apply a rigorous precondition sequence before testing. Results from modelling confirm that the WVTR method has potential to be used for measurements of water diffusion into lithium-ion pouch cells. Consequently, WVTR measurements should be possible to use as a complement or alternative method to for example Karl Fisher titration.

  1. Ontogenetic shifts in brain scaling reflect behavioral changes in the life cycle of the pouched lamprey Geotria australis

    Directory of Open Access Journals (Sweden)

    Carlos A. Salas

    2015-07-01

    Full Text Available Very few studies have described brain scaling in vertebrates throughout ontogeny and none in lampreys, one of the two surviving groups of the early agnathan (jawless stage in vertebrate evolution. The life cycle of anadromous parasitic lampreys comprises two divergent trophic phases, firstly filter-feeding as larvae in freshwater and secondly parasitism as adults in the sea, with the transition marked by a radical metamorphosis. We characterized the growth of the brain during the life cycle of the pouched lamprey Geotria australis, an anadromous parasitic lamprey, focusing on the scaling between brain and body during ontogeny and testing the hypothesis that the vast transitions in behavior and environment are reflected in differences in the scaling and relative size of the major brain subdivisions throughout life. The body and brain mass and the volume of six brain structures of G. australis, representing six points of the life cycle, were recorded, ranging from the early larval stage to the final stage of spawning and death. Brain mass does not increase linearly with body mass during the ontogeny of G. australis. During metamorphosis, brain mass increases markedly, even though the body mass does not increase, reflecting an overall growth of the brain, with particularly large increases in the volume of the optic tectum and other visual areas of the brain and, to a lesser extent, the olfactory bulbs. These results are consistent with the conclusions that ammocoetes rely predominantly on non-visual and chemosensory signals, while adults rely on both visual and olfactory cues.

    A Smart Mobile Pouch Triboelectric Nanogenerator (SMP-TENG) is introduced as a promising eco-friendly approach for scavenging biomechanical energy for powering next generation intelligent devices and smart phones. This is a cost-effective and robust method for harvesting energy from human motion, by utilizing worn fabrics as a contact material. The SMP-TENG is capable of harvesting energy in two operational modes: lateral sliding and vertical contact and separation. Moreover, the SMP-TENG can also act as a self-powered emergency flashlight and self-powered pedometer during normal human motion. A wireless power transmission setup integrated with SMP-TENG is demonstrated. This upgrades the traditional energy harvesting device into a self-powered wireless power transfer SMP-TENG. The wirelessly transferred power can be used to charge a Li-ion battery and light LEDs. The SMP-TENG opens a wide range of opportunities in the field of self-powered devices and low maintenance energy harvesting systems for portable and wearable electronic gadgets.

    Very few studies have described brain scaling in vertebrates throughout ontogeny and none in lampreys, one of the two surviving groups of the early agnathan (jawless) stage in vertebrate evolution. The life cycle of anadromous parasitic lampreys comprises two divergent trophic phases, firstly filter-feeding as larvae in freshwater and secondly parasitism as adults in the sea, with the transition marked by a radical metamorphosis. We characterized the growth of the brain during the life cycle of the pouched lamprey Geotria australis, an anadromous parasitic lamprey, focusing on the scaling between brain and body during ontogeny and testing the hypothesis that the vast transitions in behavior and environment are reflected in differences in the scaling and relative size of the major brain subdivisions throughout life. The body and brain mass and the volume of six brain structures of G. australis, representing six points of the life cycle, were recorded, ranging from the early larval stage to the final stage of spawning and death. Brain mass does not increase linearly with body mass during the ontogeny of G. australis. During metamorphosis, brain mass increases markedly, even though the body mass does not increase, reflecting an overall growth of the brain, with particularly large increases in the volume of the optic tectum and other visual areas of the brain and, to a lesser extent, the olfactory bulbs. These results are consistent with the conclusions that ammocoetes rely predominantly on non-visual and chemosensory signals, while adults rely on both visual and olfactory cues. PMID:26283894

    In this paper, the development of a three-dimensional (3D) lithium titanium oxide (LTO) pouch cell is presented to first better comprehend its thermal behavior within electrified vehicle applications, but also to propose a strong modeling base for future thermal management system. Current 3D-thermal models are based on electrochemical reactions which are in need for elaborated meshing effort and long computational time. There lacks a fast electro-thermal model which can capture voltage, current and thermal distribution variation during the whole process. The proposed thermal model is a reduce-effort temperature simulation approach involving a 0D-electrical model accommodating a 3D-thermal model to exclude electrochemical processes. The thermal model is based on heat-transfer theory and its temperature distribution prediction incorporates internal conduction and heat generation effect as well as convection. In addition, experimental tests are conducted to validate the model. Results show that both the heat dissipation rate and surface temperature uniformity data are in agreement with simulation results, which satisfies the application requirements for electrified vehicles. Additionally, a LTO battery pack sizing and modeling is also designed, applied and displays a non-uniformity of the cells under driving operation. Ultimately, the model will serve as a basis for the future development of a thermal strategy for LTO cells that operate in a large temperature range, which is a strong contribution to the existing body of scientific literature.

    To examine U.S. adult knowledge of the sugar content of sports drinks and whether this knowledge and other characteristics are associated with their sports drink consumption. Nonexperimental. Nationally representative 2011 Summer ConsumerStyles survey data. 3929 U.S. adults. The outcome variable was sports drink consumption in the past 7 days. The main exposure variable was knowledge about sports drinks containing sugar. The covariates were sociodemographic characteristics, physical activity, and weight status. Multivariable logistic regression analysis was used to estimate adjusted odds ratios (ORs) for adults consuming sports drinks ≥1 times/wk after controlling for other characteristics. Approximately 22% of adults reported consuming sports drinks ≥1 times/wk. Most adults (71%) agreed that sports drinks contain sugar; however, this agreement was not significantly associated with adults' sports drink consumption. The odds of drinking sports drinks ≥1 times/wk were significantly higher among younger adults aged 18 to 64 years (OR range: 5.46-2.71), males (OR = 2.09), high-school graduates (OR = 1.52), and highly active adults (OR = 2.09). There were disparities in sports drink consumption by sociodemographic characteristics and physical activity level; however, knowledge of sports drinks' sugar content was not associated with consumption. Understanding why some population groups are higher consumers may assist in the development of education, providing those groups with a better understanding of sports drinks' nutritional value and health consequences of excessive sugar consumption in any form.

    The thymus and parathyroid glands are derived from the third pharyngeal pouch endoderm. The mechanisms that establish distinct molecular domains in the third pouch and control the subsequent separation of these organ primordia from the pharynx are poorly understood. Here, we report that mouse embryos that lack two FGF feedback antagonists, Spry1 and Spry2, display parathyroid and thymus hypoplasia and a failure of these organ primordia to completely separate from the pharynx. We show that FGF ligands and downstream reporter genes are expressed in highly regionalised patterns in the third pouch and that sprouty gene deletion results in upregulated FGF signalling throughout the pouch endoderm. As a consequence, the initiation of markers of parathyroid and thymus fate is altered. In addition, a normal apoptotic programme that is associated with the separation of the primordia from the pharynx is disrupted, resulting in the maintenance of a thymus-pharynx attachment and a subsequent inability of the thymus to migrate to its appropriate position above the heart. We demonstrate that the sprouty genes function in the pharyngeal endoderm itself to control these processes and that the defects in sprouty-deficient mutants are, at least in part, due to hyper-responsiveness to Fgf8. Finally, we provide evidence to suggest that parathyroid hypoplasia in these mutants is due to early gene expression defects in the third pouch, whereas thymus hypoplasia is caused by reduced proliferation of thymic epithelial cells in the thymus primordium.

    Currently one of the most widely used models for the development of endovascular techniques and coiling devices for treatment of aneurysm is the elastase-induced aneurysm model in the rabbit carotid artery. Microsurgical techniques for creating an aneurysm with a venous pouch have also been established, although both techniques usually result in aneurysms less than 1 cm in diameter. We investigated whether an increase in blood flow toward the neck would produce larger aneurysms in a microsurgical venous pouch model. Microsurgical operations were performed on 11 New Zealand white rabbits. Both carotid arteries and the right jugular vein were dissected, and the right carotid artery was temporarily clipped followed by an arteriotomy. The left carotid artery was also clipped proximally, ligated distally, and sutured onto the proximal half of the arteriotomy in the right carotid artery. The venous graft was sutured onto the distal half of the arteriotomy. Digital subtraction angiography was also performed. Angiography showed patent anastomosed vessels and aneurysms in the seven surviving rabbits. Mean aneurysm measurements among surviving rabbits with patent vessels were: 13.9 mm length, 9.3 mm width, and neck diameter 4.7 mm. The resulting mean aspect ratio was 3.35 and the mean bottleneck ratio was 3.05. A large venous graft and increased blood flow toward the base of the aneurysm seem to be key factors in the creation of large venous pouch aneurysms. These large aneurysms allow testing of endovascular devices designed for large and giant aneurysms. © The Author(s) 2015.

    Inflammatory pouch complications refractory to first-line therapies remain problematic following ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). We evaluated infliximab efficacy and associations with therapeutic response. Data from individuals who underwent colectomy and IPAA for UC (2000-2014) were reviewed. Patients with chronic refractory pouchitis (CP) and Crohn's disease (CD)-like outcomes treated with infliximab were included. Pre-treatment parameters and response at median 8 (initial) and 48 weeks (sustained) were measured. Complete response was defined as symptomatic and endoscopic resolution with modified Pouchitis Disease Activity Index (mPDAI) 2. Serum was analysed for Anti-Saccharomyces cerevisiae antibodies (ASCA), anti-OmpC, anti-CBir1 and perinuclear Anti-Neutrophil Cytoplasmic Antibodies (pANCA). One hundred and fifty-two patients with CP or a CD-like phenotype were identified. Forty-two were treated with infliximab (33% male; age 32.6±2.6 years, 28.5% CD-like). Post-induction response was achieved in 74% (48% complete) and sustained response in 62.6% (29.6% complete). Mean mPDAI and C-reactive protein declined from 8.5±0.3 to 2±3.4 (p infliximab use (p Infliximab can effectively treat inflammatory pouch complications. Pre-treatment mPDAI <10 and early endoscopy may identify responders. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press. All rights reserved.

    1987-12-01

    The effect of W. somnifera on glycosaminoglycan synthesis in the granulation tissue of carrageenin-induced air pouch granuloma was studied. W. somnifera was shown to exert significant inhibitory effect on incorporation of /sup 35/S into the granulation tissue. The uncoupling effect on oxidative phosphorylation (ADP/O ratio reduction) was also observed in the mitochondria of granulation tissue. Further, Mg/sup 2 +/ dependent ATPase activity was found to be influenced by W. somnifera. W. somnifera also reduced the succinate dehydrogenase enzyme activity in the mitochondria of granulation tissue.

    Full Text Available Parental alcohol-related practices are important risk factors of adolescent drinking, but little is known about the factors associated with these parental pro-drinking practices (PPDPs. We investigated the correlates of 9 PPDPs in drinking parents of adolescents in Hong Kong.A total of 2200 students (age 14.8±2.0; boys 63.2% participated in a school-based cross-sectional survey in 2012. Analysis was restricted to 1087 (61.8% students with at least 1 drinking parent as PPDPs were much more common in these families. Logistic regression was used to identify correlates of each PPDP.Among 1087 students, the prevalence of PPDPs ranged from 8.2% for training drinking capacity to 65.7% for seeing parents drink. Only 14.8% of students had not experienced any of these practices. More frequent maternal drinking predicted parental training of drinking capacity. Older age predicted helping parents buy alcohol and parental encouragement of drinking. Adolescent girls were more likely to have received parental training of drinking capacity than boys. Higher perceived family affluence was associated with hearing parents saying benefits of drinking, and helping parents open bottle and pour alcohol.PPDPs were associated with parental drinking frequency and various socio-demographic factors. These results have implications on alcohol control programmes involving parents to tailor messages for reducing PPDPs based on the characteristics of adolescents and parents.

    The chapter explores how coffee is an integral part of our daily life. Focusing on coffee drinking at home, at work, and on the go I show that coffee consumption is a social practice. The chapter illustrates through everyday examples that coffee is more than a caffeine drug. Coffee, with or without...... caffeine, is a social lubricant. We talk to each other and share emotions with one another as we share a cup of coffee. Coffee makes conversation and we embrace coffee, to stay or to go, in the daily rhythm of our busy and global social existence. The practice and sociality of coffee consumption provide...... the coffee industry with the opportunity to make money on our coffee preferences – indeed, also for those of us who actually dislike the taste of coffee. Would you prefer coffee mixed and stirred with non-coffee products such as salt, caramel and licorice? Then you are one of us in the modern age of coffee...

    Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in drinking patterns derived from graduated frequency measures between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption-including drinking prevalence, quantity, frequency, and contexts of use-by sexual orientation. Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003-2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender. Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values drinking patterns and use of drinking contexts.

    The aim of this study was to evaluate the quality of life and functional emptying of J-pouch versus Roux-en-Y reconstruction after total gastrectomy for malignancy. This study was designed as a prospective, nonblinded, randomized, parallel clinical trial (Trial Number: MN Ostrava, 200604). With informed consent, patients undergoing gastrectomy for malignancy were randomized to J-pouch or Roux-en-Y reconstruction. The time taken for a test semisolid meal labeled with 99mTc-sulfur colloid to exit the reconstructed parts was measured by dynamic scintigraphy 1 year after resection. Quality of life was measured using the Eypasch questionnaire at the same time as functional emptying assessment. This trial was investigator-initiated. In all, 72 patients were included into the study. The time taken for the test meal to exit the postgastrectomy reconstruction was 16.5±10.0 minutes (mean ± standard deviation) in the Roux-en-Y group and 89.4±37.8 minutes in the "J-pouch" group; the difference was statistically significant (PJ-pouch appeared to be a linear decreasing function compared to the exponential pattern seen in the Roux-en-Y group. The quality of life measurement showed scores of 106±18.8 points (mean ± standard deviation) in the Roux-en-Y group compared to 122±22.5 points in the J-pouch group; the difference was statistically significant (P=0.0016). There were no important adverse events. After total gastrectomy, a J-pouch reconstruction empties more slowly and is associated with higher quality of life compared to Roux-en-Y reconstruction. Whether these two observations have a direct causative link remains unanswered.

    Ileal pouch-anal anastomosis (IPAA) is recommended for patients with ulcerative colitis (UC) in terms of surgical treatment. Measuring surgical complications of IPAA and long-term quality of life (QOL) are important to achieve an acceptable risk/benefit ratio for patients with UC. Patients with UC who underwent total proctocolectomy (TPC) with IPAA from February 2008 to July 2016 at our institute were included. Early surgical complications were defined as mechanical/infectious events within one month after IPAA. Assessment of QOL was performed using the Cleveland Global Quality of Life instrument (CGQL), with 50% improvement as a cut-off value. Demographic and clinical variables were compared with univariable analysis and step-wise logistic regression models were also performed. A total of 58 eligible patients had a median follow-up time of 78.5 months [interquartile range (IQR), 34.4-92.8] from February2008 to March 2017, including 25 cases (43.1%) developed early surgical complications. Age at pouch surgery and excessive blood loss were risk factors associated with early surgical complications (p < 0.05). In multivariate analysis, older age at surgery [odds ratio (OR), 1.05; 95% confidence interval (CI), 1.01-1.1] and significant blood loss (≧400 ml) (OR, 4.31; 95% CI, 1.21-16.87) were contributing factors for developing early surgical complications. The CGQL score was significantly increased after IPAA (0.728 ± 0.151 vs. 0.429 ± 0.173, p < 0.001). Early surgical complications (OR, 5.55; 95%CI, 1.44-21.37), older age at surgery (OR, 1.06; 95% CI, 1.01-1.12) and use of immunomodulatory (OR, 17.50; 95% CI, 1.52-201.39) were associated with poor long-term QOL. The study demonstrated that early surgical complications might contribute to develop a poor CGQL score, suggesting intentional control of risk factors associated with early surgical complications should be taken into consideration for patients with UC for pouch surgery.

    Treatment of subclinical carriers of Streptococcus equi subsp. equi with a gelatine-penicillin formulation deposited in the guttural pouch has been empirically proposed, but data on local tissue penicillin concentrations after treatment are lacking. We analysed tissue levels of penicillin after administration into the guttural pouches of four healthy horses. Two horses received local treatment with gelatine-penicillin and two horses received local treatment with an intramammary formulation of penicillin. Tissues were harvested for analysis either 12 or 24 h later. Results indicate that local treatment may be effective, but more research on optimal drug formulations in a larger sample size is warranted. © 2016 Australian Veterinary Association.

    This study shows the rapid and differential production of the 40-43 kDa and the 70-90 kDa alpha1-acid glycoprotein (AGP) fucosylated glycoforms after treatment of the dorsal air pouch with bacterial lipopolysaccharide (LPS), HgCl(2) or Freund's complete adjuvant (FCA). The 40-43 kDa and the 70-90 kDa AGP production is peaked 1-3 h post-LPS treatment. We observed that the responses to LPS and FCA are similar in that both AGP isoforms are induced whereas they differ in that the FCA exhibits a 6 h lag period. The response to HgCl(2,) however, exhibits the specific biphasic induction only of the 40-43 kDa AGP. The serum 40-43 kDa AGP glycoform gradually increases in response to all of the above stimulants and peaks by 24 h post- treatment. The increase of the 70-90 kDa AGP levels in the air pouch occurs in association with the accumulation of polymorphonuclear (PMN) cells while dexamethasone (DEX) increases only the 40-43 kDa AGP production in the absence of PMN accumulation. Macrophage-monocyte lineage cells forming the air pouch lining tissue may potentially be the cells that secrete the 40-43 kDa AGP while polymorphonuclear cells that infiltrate the air pouch secrete the 70-90 kDa AGP. The 40-43 kDa and 70-90 kDa AGP production induced by LPS in the air pouch precedes that of interleukin-1 (IL-1) or interleukin-6 (IL-6) while the 40-43 kDa AGP glycoform potentially increases IL-6 production by air pouch PMN exudate cells. These significant differences suggest a local pro-inflammatory role of AGP. Honeybee venom suppressed arthritis development and exhibited differential local or systemic regulation of AGP in serum vs. air pouch exudate or synovial fluid. This study with the air pouch model of facsimile synovium tissue suggests that local alpha1-acid glycoprotein (AGP) production may contribute to pro-inflammatory and anti-inflammatory activities during the local acute phase response or during chronic inflammatory stress as in arthritis.

    1993-08-01

    In the present study, we investigated (a) the effects of the extract of Ruscus aculeatus, which is used to increase peripheral venous tone, on the diameter of arterioles (ID range 10-70 microns) and venules (ID range 20-135 microns) of hamster cheek pouch microvasculature in vivo and (b) the influence of temperature on the observed effects. For microcirculatory measurements, the preparations were placed under an intravital microscope and coupled to a closed-circuit TV (ccTV) system. The TV monitor display was used to obtain arteriolar and venular ID recordings (always at the same site) by an image shearing device. For systemic intravenous (i.v.) administration, the measurements were performed every 10 min, before (control) and after injection of the extract (5 mg/kg). During topical application, the extract was tested, in different concentrations, at 25 degrees, 36.5 degrees, and 40 degrees C. Systemic i.v. administration of Ruscus extract evoked venular constriction and did not affect the arteriolar diameter or mean arterial pressure (MAP). Topical application of Ruscus extract elicited concentration- and temperature-dependent responses in the vessels. At 25 degrees C, arterioles and venules dilated; at 36.5 degrees C, the arterioles remained unchanged while the venules constricted, and at 40 degrees C, the arterioles remained unchanged or constricted depending on the concentration used while the venules further constricted. The effects of Ruscus extract observed in vivo at the microcirculatory level further support the data previously reported on larger vessels and on patients with venous insufficiency.

    Full Text Available This study aimed to investigate the effects of aqueous cinnamon extract (ACE on 7, 12-Dimethylbenz[a]anthracene (DMBA-induced oral carcinogenesis in hamster cheek pouch (HCP mucosa. Sixty male Syrian hamsters were randomly divided into six equal groups. The hamsters of groups I, II and III received no treatment, DMBA and ACE respectively, for 16 weeks. Groups IV and V were handled as group II and concomitantly treated with ACE for the same period and additionally group V received ACE for other 16 weeks after the stoppage of DMBA application. Group VI hamsters were handled as group III and additionally received DMBA for other 16 weeks after the stoppage of ACE supplementation. Hamsters of each group were euthanized according to the experimental schedule. The buccal pouches were and prepared for H&E stain, PAS reagent, CD3 and PDGF immunohistochemical reactivity. All groups showed dysplastic changes with varying degrees except groups I and III. Deep invasive carcinomas were recorded in 90% of the samples of group II, 60% of group IV, 50% of group V and 40% of group VI. From the previous results, it can be concluded that ACE has the potentiality preventing oral cancer initiation better than inhibiting oral cancer progression.

  1. Reduced angiotensin II levels cause generalized vascular dysfunction via oxidant stress in hamster cheek pouch arterioles.

    We investigated the effect of suppressing plasma angiotensin II (ANG II) levels on arteriolar relaxation in the hamster cheek pouch. Arteriolar diameters were measured via television microscopy during short-term (3-6days) high salt (HS; 4% NaCl) diet and angiotensin converting enzyme (ACE) inhibition with captopril (100mg/kg/day). ACE inhibition and/or HS diet eliminated endothelium-dependent arteriolar dilation to acetylcholine, endothelium-independent dilation to the NO donor sodium nitroprusside, the prostacyclin analogs carbacyclin and iloprost, and the KATP channel opener cromakalim; and eliminated arteriolar constriction during KATP channel blockade with glibenclamide. Scavenging of superoxide radicals and low dose ANG II infusion (25ng/kg/min, subcutaneous) reduced oxidant stress and restored arteriolar dilation in arterioles of HS-fed hamsters. Vasoconstriction to topically-applied ANG II was unaffected by HS diet while arteriolar responses to elevation of superfusion solution PO2 were unaffected (5% O2, 10% O2) or reduced (21% O2) by HS diet. These findings indicate that sustained exposure to low levels of circulating ANG II leads to widespread dysfunction in endothelium-dependent and independent vascular relaxation mechanisms in cheek pouch arterioles by increasing vascular oxidant stress, but does not potentiate O2- or ANG II-induced constriction of arterioles in the distal microcirculation of normotensive hamsters.

    The short circuit of lithium-ion batteries induced by mechanical abuse is a great concern in electric vehicle design. It remains a challenge to fully understand the nature of the mechanical damage process with the aim of improving battery crash safety. The present paper investigates the evolution of the damage process for a lithium-ion pouch cell under indentation by loading the cell to various force levels. A significant inflection point on the force-indentation curve is observed before the force peak. Post-mortem examinations indicate that the characteristic change in the local slope of the curve is related to the change occurring at the local interfaces, including three phenomena - formation of tight adhesion on the anode-separator interfaces, delamination in the separators and decoating of graphite particles from the anodes. Analysis of the fracture sequence at the onset of short circuit clearly shows that the number of short-circuited electrode pairs is equal to the number of anode layers adhered with delaminated separator material before fracture occurs. The experimental study in the present paper implies that the inflection point on the force-indentation curve may be an indicator of damage initiation inside pouch cells under indentation.

    The application of boron neutron capture therapy (BNCT) mediated by liposomes containing (10)B-enriched polyhedral borane and carborane derivatives for the treatment of head and neck cancer in the hamster cheek pouch oral cancer model is presented. These liposomes are composed of an equimolar ratio of cholesterol and 1,2-distearoyl-sn-glycero-3-phosphocholine, incorporating K[nido-7-CH3(CH2)15-7,8-C2B9H11] (MAC) in the bilayer membrane while encapsulating the hydrophilic species Na3[ae-B20H17NH3] (TAC) in the aqueous core. Unilamellar liposomes with a mean diameter of 83 nm were administered i.v. in hamsters. After 48 h, the boron concentration in tumors was 67 ± 16 ppm whereas the precancerous tissue contained 11 ± 6 ppm, and the tumor/normal pouch tissue boron concentration ratio was 10:1. Neutron irradiation giving a 5-Gy dose to precancerous tissue (corresponding to 21 Gy in tumor) resulted in an overall tumor response (OR) of 70% after a 4-wk posttreatment period. In contrast, the beam-only protocol gave an OR rate of only 28%. Once-repeated BNCT treatment with readministration of liposomes at an interval of 4, 6, or 8 wk resulted in OR rates of 70-88%, of which the complete response ranged from 37% to 52%. Because of the good therapeutic outcome, it was possible to extend the follow-up of BNCT treatment groups to 16 wk after the first treatment. No radiotoxicity to normal tissue was observed. A salient advantage of these liposomes was that only mild mucositis was observed in dose-limiting precancerous tissue with a sustained tumor response of 70-88%.

    Ureteric duplication is a rarely seen malformation of the urinary tract more commonly seen in females. We report 2 cases of robot-assisted laparoscopic radical cystoprostatectomy (RALRCP) with bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch formation in patients with duplicated right ureters. Two male patients (53 and 68 years old) underwent transurethral resection of a bladder tumor that revealed high-grade muscle invasive transitional cell carcinoma, with no metastases. We performed RALRCP and intracorporeal Studer pouch formation. A duplicated right ureter was observed during the procedures in both patients. Left ureter distal segment was spatulated 2cm long and anastomosed using running 4/0 Vicryl to the right ureter at its bifurcation where it forms a single lumen without spatulation. All 3 ureters were catheterized individually. A Wallace type uretero-ileal anastomosis was performed between the ureters and the proximal part of the Studer pouch chimney. Although ureteric frozen section analysis suggested ureteric carcinoma in situ in patient 1, postoperative pathologic evaluation was normal. Frozen section and final postoperative pathologic evaluations were normal in patient 2. Duplicated ureters might be underdiagnosed on CT. The presence of a duplicated ureter is not a contraindication to RALRCP and intracorporeal Studer pouch formation. The da Vinci-S surgical robot is very safe for performing this complicated procedure. Frozen section analysis of ureters during radical cystectomy for bladder cancer might not reliably diagnose the pathologic condition and might overestimate the disease in the ureters.

    A total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is considered the surgery of choice for definitive management of familial adenomatous polyposis (FAP) and some patients with ulcerative colitis (UC). However, this surgical treatment is often associated with pouchitis, a long-term complication that occurs mostly in UC patients. The purpose of this study was to better define the molecular background of pouchitis. A microarray-based survey was performed using pouch mucosal samples collected from 28 and 8 patients undergoing surgery for UC and FAP, respectively. There were 4,770 genes that significantly differentiated uninflamed from inflamed mucosal samples, and their functional features were represented mostly by metabolic and cell proliferation pathways. In contrast, functional analyses of aberrantly expressed genes between UC and FAP samples, irrespective of mucosal inflammation status, revealed multiple pathways and terms that were linked to changes in immune response. Interestingly, the comparison of uninflamed UC and FAP samples identified a set of 29 altered probe sets, including an inflammation-related transcript encoding a Charcot-Leyden crystal (CLC) protein. The most distinct changes in gene expression profiles differentiating uninflamed UC and FAP pouch mucosal samples were attributed to the Gene Ontology category innate immune response. Our study confirmed that alterations in immune responses can be found between patients who underwent surgery for UC and FAP, independent of the pouch inflammation status. This observation may be important when managing IPAA patients.

    Full Text Available Background: In recent years, trichomoniasis has emerged as the most common sexually transmitted disease and limited data are available on the effective screening technique for the diagnosis of Trichomonas vaginalis. Aim : The aim was to compare and evaluate different diagnostic methods like wet mount microscopy, In Pouch TV culture, and Polymerase chain reaction (PCR to establish which method or combination of methods was most effective for detection of Trichomonas vaginalis in vaginal swab specimens. Settings and Design : This is a cross-sectional study. Materials and Methods : A total of 200 patients complaining of vaginal discharge were included in the study. Three vaginal swabs were screened for trichomoniasis by wet mount microscopy, In Pouch TV culture system and PCR, using TVK3 and TVK7 specific primers. Results : Of the 200 cases studied, 36 (18% were positive by wet mount microscopy, 44 (22% by In Pouch TV culture system and 60(30% by PCR. Sensitivity and specificity of wet mount were 60% and 100%, respectively, whereas sensitivity and specificity of the In Pouch TV culture system were 73.33% and 100%, respectively when compared to PCR. Conclusion : Comparison of different methods showed that at least two techniques, such as wet mount microscopy and culture have a better chance of detection of T. vaginalis infection. Diagnosis of trichomoniasis by PCR was found to be highly specific and sensitive, but its availability and cost effectiveness limit its use in routine diagnostic laboratories.

    Full Text Available Background: Use of pesticides deceives of indisputable advantage, however remainders of pesticides in drinking water might represent potential danger for health on foodstuffs. In European Union (EU pesticides and their relevant metabolic, degrading and reactive products, with exception for aldrin, dieldrin, heptaclor and heptaclor epoxide, should not exceed the concentration of 0.10 μg/l. At limit value 0.10 μg/l we wish to achieve null value these substances in drinking water.Methods: In years 2004 and 2005 monitoring of pesticides in drinking waters on pipes of consumers in all larger towns in state was done. Majority of pesticides were analysed by gas chromatography in combination with mass spectrometry while fluid cromatography was used primarily for badly volatile or polar and termolabile compound.Results: Results of analyses of drinking water and of ground waters for years 2004 and 2005 showed that levels of atrazine, desethyl-atrazine and 2.6 dichlorobenzamide were exceeded few times when compared to required levels. In 2005 bentazone, MCPP, metolachlor, terbuthylazin were exceeded. In 2004 concentration of pesticides were exceeded in 25 samples in 15 different areas, supplying 183,881 inhabitants. In 2005 concentration of pesticides were exceeded in 31 samples in 14 different areas, supplying 151,297 inhabitants. The distribution shows, that contamination was present mostly in the northeast part of Slovenia, where intensive agriculture takes place.Conclusions: Received status review acquired by monitoring of pesticides in drinking water is only an assessment of circumstances that will gain in representativity by enlarged number of sampling locations and longer observation time. For assessment of trends of pollution of drinking water in Slovenia it will be necessary to monitor concentration of pesticides through longer period. We could have unpolluted drinking water only with restricted use of pesticides on water-protection ranges or

    Inducing angiogenesis is one hallmark of cancer. Tumor induced neovasculature is often characterized as leaky, tortuous and chaotic, unlike a highly organized normal vasculature. Additionally, in the course of carcinogenesis, angiogenesis precedes a visible lesion. Tumor cannot grow beyond 1-2 mm in diameter without inducing angiogenesis. Therefore, capturing the event of angiogenesis may aid early detection of pre-cancer -important for better treatment prognoses in regions that lack the resources to manage invasive cancer. In this study, we imaged the neovascularization in vivo in a spontaneous hamster cheek pouch carcinogen model using a, non-invasive, label-free, high resolution, reflected-light spectral darkfield microscope. Hamsters' cheek pouches were painted with 7,12-Dimethylbenz[a]anthracene (DMBA) to induce pre-cancerous to cancerous changes, or mineral oil as control. High resolution spectral darkfield images were obtained over the course of pre-cancer development and in control cheek pouches. The vasculature was segmented with a multi-scale Gabor filter with an 85% accuracy compared with manually traced masks. Highly tortuous vasculature was observed only in the DMBA treated cheek pouches as early as 6 weeks of treatment. In addition, the highly tortuous vessels could be identified before a visible lesion occurred later during the treatment. The vessel patterns as determined by the tortuosity index were significantly different from that of the control cheek pouch. This preliminary study suggests that high-resolution darkfield microscopy is promising tool for pre-cancer and early cancer detection in low resource settings.

    Rheumatoid arthritis (RA) is a systemic inflammatory disease with cardiovascular complications as the leading cause of morbidity. Carvedilol is an adrenergic antagonist which has been safely used in treatment of several cardiovascular disorders. Given that carvedilol has powerful antioxidant/anti-inflammatory properties, we aimed to investigate its protective potential against arthritis that may add further benefits for its clinical usefulness especially in RA patients with concomitant cardiovascular disorders. Two models were studied in the same rat; adjuvant arthritis and subcutaneous air pouch edema. Carvedilol (10 mg/kg/day p.o. for 21 days) effectively suppressed inflammation in both models with comparable efficacy to the standard anti-inflammatory diclofenac (5 mg/kg/day p.o.). Notably, carvedilol inhibited paw edema and abrogated the leukocyte invasion to air pouch exudates. The latter observation was confirmed by the histopathological assessment of the pouch lining that revealed mitigation of immuno-inflammatory cell influx. Carvedilol reduced/normalized oxidative stress markers (lipid peroxides, nitric oxide and protein thiols) and lowered the release of inflammatory cytokines (TNF-α and IL-6), and eicosanoids (PGE{sub 2} and LTB{sub 4}) in sera and exudates of arthritic rats. Interestingly, carvedilol, per se, didn't present any effect on assessed biochemical parameters in normal rats. Together, the current study highlights evidences for the promising anti-arthritic effects of carvedilol that could be mediated through attenuation of leukocyte migration, alleviation of oxidative stress and suppression of proinflammatory cytokines and eicosanoids. - Highlights: ► Carvedilol possesses promising anti-arthritic properties. ► It markedly suppressed inflammation in adjuvant arthritis and air pouch edema. ► It abrogated the leukocyte invasion to air pouch exudates and linings. ► It reduced/normalized oxidative stress markers in sera and exudates of

    Mast cell (MC) activation in the hamster cheek pouch cancerization model is associated with the increase in tumor cell proliferation, mediated in turn by tryptase, a protease released from mast cell granules after activation. Tryptase induces tumor cell proliferation through the activation of PAR-2 (protease activated receptor-2) on the plasma membrane of carcinoma cells. The therapeutic success of boron neutron capture therapy mediated by boronophenylalanine (BPA-BNCT) in tumor control in the hamster cheek pouch oral cancer model has been previously reported by our laboratory. Early effects of BPA-BNCT on tumors of the hamster cheek pouch include a reduction in DNA-synthesis with the concomitant decrease in the proliferation of malignant cells. The aim of the present study was to investigate the early histological changes in mast cells after BPA-BNCT in tumors and premalignant tissue of the hamster cheek pouch. Tumor-bearing pouches were treated with BPA-BNCT or beam only (neutron irradiation without prior administration of the boron compound) and sacrificed 1day after treatment. The samples were fixed in Carnoy fixative and stained with alcian blue-safranin to identify all the populations of mast cells. Total, active and inactive mast cells (MC) were counted in the connective tissue and the adventitious tissue underlying the pouch wall and at the base of the tumors in pouches treated with BPA-BNCT, in keeping with a previously described technique. BPA-BNCT induced a marked reduction in the total number of mast cells in the pouch (pBNCT and beam only elicited a qualitative change in the secretion modality of the granule content. Although further studies are needed to evaluate the subcellular effect of BNCT on mast cell granule secretion, the reduction in cell proliferation induced by BPA-BNCT would be partially due to the decrease in total mast cells in the hamster check pouch.

    Principal glycoproteins and amino acids were determined in gastric juice obtained from Heidenhain pouches of Labrador pure-bred dogs. Secretions were stimulated by food, pentagastrin or histamine. Non-stimulated fasting secretions served as controls. All samples showed the presence of galactose, glucosamine, galactosamine, fucose, glucose, mannose and sulfate. Galactose and glucosamine were found in equimolar amount and the galactose to galactosamine ratio was 2:1. Concentrations of most carbohydrate components studied were higher in fasting than in stimulated secretions. Outputs of some of these components were lower in fasting than in stimulated secretions. Modes of stimulation used did not significantly affect the outputs of principal glycoproteins studied. Compared with human gastric secretions studied by others, using similar methods, certain differences were found particularly in the relationship between some carbohydrate components and between amino acids.

    We examined the content protection characteristics of the PID (Pouch in Dispenser) when it was used in the usual manner and when it was polluted artificially. When the PID was used in the usual manner, the nozzle was opened, and experiments were carried out with and without air-blowing. The invasion of bacteria into the PID was not detected. Also, no bacteria were detected in the material poured from the nozzle of the PID. When 3 strains of bacteria suspensions were intentionally smeared on the nozzle of the PID, invasion of bacteria was observed. When the PID was wiped with a dirty cloth, no invasion of bacteria into the PID was detected. It may be necessary to label the PID with the instruction that the nozzle should not be touched. The effected of changes in the water activity and pH, and the preservatives used, may also need to be considered, depending on the contents in the PID.

    Full Text Available OBJECTIVE: Blake's pouch cyst (BPC is a midline cystic malformation of the posterior fossa, within Dandy-Walker's complex (DWC, often associated with hydrocephalus. Endoscopic third ventriculostomy (ETV has been an alternative to conventional methods for BPC treatment. This study aimed at reporting our experience with ETV in a series of patients with BPC. METHODS: Of 33 patients diagnosed with midline posterior fossa cyst, 26 met the protocol criteria for DWC, and eight subjects with BPC were selected (aged one month to two years old. All cases were treated with ETV. RESULTS: Five patients were male; and three were prenatally diagnosed. They had hydrocephalus and motor deficiencies. Motor assessment at a five-year follow-up yielded normal findings. All patients improved, and only one had residual cognitive dysfunction, despite overall neurological improvement. There were no complications. CONCLUSIONS: ETV was a safe and effective procedure, reducing risks and morbidity associated with open surgery and shunt-related problems.

    Seven active male subjects cycled for 60 min at 29.5 (0.8)% peak work rate on three separate occasions in a hot environmental condition [36.0 (0.1) degrees C, 60 (1)% relative humidity] in order to determine the reproducibility of a closed-pouch sweat collection technique for sweat composition at the scapula, forearm and thigh. To confirm that sweat composition was not influenced by between-trial variations in sudomotor drive, local sweat rate, whole-body sweat rate, heart rate (HR), rectal temperature (T(re)) and mean skin temperature (T(sk)) responses were also measured, consequently reproducibility was also established for these variables. Sweat composition did not differ among trials, with the mean coefficients of variation (CVs) for sweat [Na(+)], [K(+)] and pH being 10.4 (7.4)%, 8.1 (6.5)% and 1.3 (1.1)%, respectively. Local sweat rates did not differ among the three trials (P>0.05) although whole-body sweat rate was reduced in the third trial (Psweat rates, respectively. Between-trial differences were not evident for T(re), T(sk) or HR with mean CVs of 0.3 (0.2)%, 0.7 (0.6)% and 3.9 (1.7)%, respectively, although HR tended to be greater in the first trial ( P=0.08). It is proposed that moderate variations in sweat composition were influenced by variations in the local sweat rate, which were induced by application of the pouch.

    The left atrial septal pouch (LASP) is formed by incomplete fusion of the septum primum and septum secundum, leaving a cavity open towards the left atrium, but without interatrial shunting. There is no recommendation concerning strategy in the presence of a LASP, especially in the setting of stroke. The aim of this review was to determine whether the LASP could be incriminated as the aetiology of a stroke. We included all pertinent publications on the subject, and calculated hazard ratios for ischaemic stroke and cryptogenic stroke. There were only five case-control studies concerning the LASP, involving 516 stroke patients and 779 controls. Overall LASP prevalence was 21%, with a slightly higher prevalence in the cryptogenic stroke group (26%), but this difference was not statistically significant (P=0.27). In a random-effects meta-analysis, there was no difference between controls and patients with ischaemic stroke (hazard ratio 1.20, 95% confidence interval 0.96-1.53; P=0.14). Cryptogenic stroke appeared more frequently in patients with LASP (hazard ratio 1.53, 95% confidence interval 1.07-2.24; P=0.02), but this was driven by only one severely underpowered study. The published case reports demonstrated that thrombus formation inside the pouch can occur in the presence of major predisposing factors. The LASP can be a site for thrombus formation, leading to embolic events, but its presence does not correlate with an increased incidence of stroke. Associated factors should be taken into consideration in the setting of stroke. Further studies are necessary to validate a possible relationship with cryptogenic stroke.

  1. A characterization of anaerobic colonization and associated mucosal adaptations in the undiseased ileal pouch.

    LENUS (Irish Health Repository)

    Smith, F M

    2012-02-03

    INTRODUCTION: The resolution of pouchitis with metronidazole points to an anaerobic aetiology. Pouchitis is mainly seen in patients with ulcerative colitis pouches (UCP). We have recently found that sulphate reducing bacteria (SRB), a species of strict anaerobe, colonize UCP exclusively. Herein, we aimed to correlate levels of different bacterial species (including SRB) with mucosal inflammation and morphology. METHODS: Following ethical approval, fresh faecal samples and mucosal biopsies were taken from 9 patients with UCP and 5 patients with familial adenomatous polyposis pouches (FAPP). For the purposes of comparison, faecal samples and mucosal biopsies were also taken from the stomas of 7 of the 9 patients with UC (UCS). Colonization by four types of strict anaerobes (SRB, Clostridium perfringens, Bifidobacteria and Bacteroides) as well as by three types of facultative anaerobes (Enterococci, Coliforms and Lactobacilli) was evaluated. Inflammatory scores and mucosal morphology were assessed histologically in a blinded fashion by a pathologist. RESULTS: In general, strict anaerobes predominated over facultative in the UCP (P = 0.041). SRB were present in UCP exclusively. Even after exclusion of SRB from total bacterial counts, strict anaerobes still predominated. In the UCS, facultative anaerobes predominated. Strict and facultative anaerobes were present at similar levels in the FAPP. Enterococci were present at significantly reduced levels in the UCP when compared with the UCS (P = 0.031). When levels of SRB and other anaerobic species were individually correlated with mucosal inflammation and morphology, no trends were observed. CONCLUSION: We have previously identified that SRB exclusively colonize UCP. In addition we have now identified a novel increase in the strict\\/facultative anaerobic ratio within the UCP compared to UCS. These stark differences in bacterial colonization, however, appear to have limited impact on mucosal inflammation or morphology.

    Many college students drink heavily and experience myriad associated negative consequences. This review suggests that a developmental perspective can facilitate a better understanding of college drinking. Specifically, using an emerging adulthood framework that considers the ongoing role of parents and neurodevelopmental processes can provide insight into why students drink. Most college students drink and tend to drink more and more heavily than their non–college-attending peers. These drinking patterns are affected by environmental and temporal characteristics specific to the college environment, including residential campus living, the academic week, and the academic year. Additional psychosocial factors are of particular relevance to the drinking behavior of college-age people, and include exaggerated peer norms, the development and use of protective behavioral strategies, and mental health considerations. Understanding the unique interaction of person and environment is key to designing prevention/intervention efforts. PMID:27159817

    Hamster cheek pouches were exposed to 2-chloroethyl ethyl sulfide [CEES, half-mustard gas (HMG)] at a concentration of 0.4, 2.0, or 5.0 mg/ml for 1 or 5 min. Twenty-four hours post-HMG exposure, tissue damage was assessed by both stereomicrography and optical coherence tomography (OCT). Damage that was not visible on gross visual examination was apparent in the OCT images. Tissue changes were found to be dependent on both HMG concentration and exposure time. The submucosal and muscle layers of the cheek pouch tissue showed the greatest amount of structural alteration. Routine light microscope histology was performed to confirm the OCT observations.

    This study aimed at analyzing nurses (re)construction process regarding the meanings of ostomy, ostomized patients, nursing care and the professional role after they wore an ostomy appliance. This activity is a teaching strategy applied at the Enterostomal Therapy Nursing Education Program. Two major units were identified after the analysis of students speeches: "being an ostomized person" and "being a professional". When students wore the pouches they felt as ostomized patients experiencing a violation of their identity and quality of life that promotes profound changes in daily life. These symbolic contents cause a crisis regarding the meaning of being a professional as until this experience, nursing care seemed fragmented to them. Recognizing a previous care performed as a technical action mainly directed to the ostomy and the pouch, students were able to visualize a future care, that is holistic and considers the ostomized human being, enabling them to incorporate affective, symbolic and relational dimensions.

    Monkeypox is a zoonosis clinically similar to smallpox in humans. Recent evidence has shown a potential risk of increased incidence in central Africa. Despite attempts to isolate the virus from wild rodents and other small mammals, no reservoir host has been identified. In 2003,Monkeypox virus (MPXV) was accidentally introduced into the U.S. via the pet trade and was associated with the Gambian pouched rat (Cricetomys gambianus). Therefore, we investigated the potential reservoir competence of the Gambian pouched rat for MPXV by utilizing a combination of in vivo and in vitro methods. We inoculated three animals by the intradermal route and three animals by the intranasal route, with one mock-infected control for each route. Bioluminescent imaging (BLI) was used to track replicating virus in infected animals and virological assays (e.g. real time PCR, cell culture) were used to determine viral load in blood, urine, ocular, nasal, oral, and rectal swabs. Intradermal inoculation resulted in clinical signs of monkeypox infection in two of three animals. One severely ill animal was euthanized and the other affected animal recovered. In contrast, intranasal inoculation resulted in subclinical infection in all three animals. All animals, regardless of apparent or inapparent infection, shed virus in oral and nasal secretions. Additionally, BLI identified viral replication in the skin without grossly visible lesions. These results suggest that Gambian pouched rats may play an important role in transmission of the virus to humans, as they are hunted for consumption and it is possible for MPXV-infected pouched rats to shed infectious virus without displaying overt clinical signs.

    This case report regards pregnancy and delivery of a patient who had undergone proctocolectomy and ileo-pouch-anal-anastomosis (IPAA) for ulcerative colitis. The patient delivered through cesarean section and experienced serious complications postpartum. Such complications have been described in association with Chron’s disease and have never been described after proctocolectomy and IPAA for ulcerative colitis. This case report suggests that the limit between these two diseases is not sharp.

    One of the best strategies to prevent the occurrence of oral cancer is to eliminate oral precancers and block their further malignant transformation. Previous studies showed that photosan-mediated photodynamic therapy (photosan-PDT) is very effective for human head and neck cancers. To avoid the systemic photodynamic toxicity of photosan, this study was designed to use a topical photosan-PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. Twelve 10-week-old male Syrian golden hamsters were used in this study. DMBA was applied to the left buccal pouches thrice a week for 8 to 10 weeks and mineral oil was painted on the right buccal pouches thrice a week for 8 to 10 weeks as the normal controls. Six hamsters were euthanized for tissue harvest. Precancerous lesions of moderate to severe dysplasia were consistently induced and proven by histological examination. These induced precancerous lesions in the remaining 6 hamsters were used for testing the efficacy of topical photosan-PDT. Before PDT, fluorescence spectroscopy was used to determine when protoporphyrine IX (PpIX) reached its peak level in the lesional epithelial cells after topical application of photosan-gel. We found that PpIX reached its peak level in precancerous lesions about 13.5 min after topical application of photosan-gel. The precancerous lesions in 4 hamsters were treated with topical photosan-PDT using the 635-nm LED light once or twice a week. Complete regression of the precancerous lesions was found after 2-4 PDT treatments by visual and histological examination. Our findings indicate that topical photosan-PDT is a very effective treatment modality for DMBA-induced hamster buccal pouch precancerous lesions.

    Total mesorectal excision (TME) has become the recommended method for treatment of cancer in the middle or lower third of the rectum. Thus very low anastomoses are necessary to preserve continence, and pouch reconstruction is favored. It is unclear whether the level of anastomosis is important for continence and quality of life in colonic J-pouch reconstruction. In this investigation all patients were included who underwent curative elective anterior continuity resection with colorectal or coloanal J-pouch reconstruction for primary rectal cancer between January 2001 and December 2004. Exclusion criteria were distant metastases and any signs of recurrence at the time of investigation. Evaluation of continence performance by Wexner and Holschneider questionnaire and quality of life using the QLQ-C30 and QLQ-CR38 (EORTC) questionnaires was done 220 +/- 38 days after closure of the protective Ileostomy, which was performed 106 +/- 48 days after primary intervention. Fifty-two patients (79%) were analyzed. Colopouch rectal anastomosis was performed in eighteen cases and colopouch anal anastomosis in thirty-four cases. Fifty percent of the patients in both groups were continent for solid stool. Patients with a colopouch anal anastomosis had a significantly higher rate of incontinence for liquid stool, however. They took stool-regulating medicine more frequently and complained of fecal soiling and a restricted quality of life. Patients with a colopouch anal anastomosis had a significantly lower score on the most important points of the QLQ-C30 (emotional functioning, social functioning, pain, and quality of life). The same applied to the QLQ-CR38 for body image and problems with defecation. The quality of life of patients with a colopouch anal anastomosis was still considered acceptable compared with reference data for the normal healthy population, however. Both continence and quality of life are substantially affected by the level of the anastomosis after colonic pouch

    Full Text Available We used the mouse air pouch model of inflammation to study the interaction between cytokines, prostaglandin E2 (PGE2 and cell migration during the various phases of acute local inflammation induced by carrageenan. In serum, the levels of interleukin 1 (IL-1, interleukin 6 (IL-6, tumour necrosis factor (TNF, serum amiloid-A (SAA and Fe++ were never different from controls, indicating that no systemic inflammatory changes were induced. Locally the exudate volume and the number of leukocytes recruited into the pouch increased progressively until 7 days after carrageenan. The same was true for PGE2 production. We could not measure IL-1 but the production of IL-6 and TNF reached a maximum after 5-24 h then quickly decreased. Anti-TNF antibodies inhibited cell migration by 50% 24 h after treatment. Pretreatment with interleukin 10 (IL-10 inhibited TNF production almost completely and cell migration by 60%. Carrageenan-induced inflammation was modulated by anti-inflammatory drugs. Pretreatment with dexamethasone (DEX or indomethacin (INDO inhibited cell migration and reduced the concentration of TNF in the exudate. Production of PGE2 or vascular permeability did not correlate with the number of cells in the pouch. Local TNF seems to play an important role in this model, particularly for leukocyte migration in the first phase of the inflammatory process. In conclusion, the air pouch seems to be a good model for studying the regulation of the early events of local inflammation, particularly the role of cytokines and cell migration.

    The purpose of our study was to determine the utility of contrast enemas for detecting clinically relevant anastomotic strictures after total proctocolectomy and ileal pouch-anal anastomosis and to facilitate management by defining a critical anastomotic caliber at or below which obstruction is likely to develop after ileostomy closure. Our radiology database revealed 42 patients with contrast enemas after total proctocolectomy and ileal pouch-anal anastomosis who fulfilled our exclusion criteria. The initial postoperative contrast enemas were reviewed blindly to determine the diameter of the ileoanal anastomosis. The diagnosis of a stricture was made only if the patient had signs of intestinal obstruction after ileostomy closure with confirmation on follow-up contrast enema or sigmoidoscopy and clinical improvement after anastomotic dilatation. The data were then correlated to determine if there was a critical anastomotic caliber at or below which such strictures were likely to develop. Using this threshold value, the sensitivity and specificity of routine contrast enemas for detecting clinically relevant anastomotic strictures were then determined. Six (14%) of the 42 patients who underwent total proctocolectomy and ileal pouch-anal anastomosis had strictures at the ileoanal anastomosis on contrast enemas. The mean diameter of the anastomosis was 5.8 mm in the six patients with anastomotic strictures versus 15 mm in the 36 patients without strictures (p = 0.0002). If an anastomotic diameter of 8 mm is defined as the critical caliber at or below which clinically relevant strictures are present, the sensitivity of contrast enemas for detecting strictures at the ileoanal anastomosis was 100% (six of six patients) and the specificity was 92% (33 of 36 patients). Routine contrast enema after total proctocolectomy and ileal pouch-anal anastomosis is a sensitive test for detecting clinically relevant strictures at the ileoanal anastomosis when an anastomotic diameter of

    Drinking habits are socially patterned and social networks influence individuals' drinking behaviors. Previous studies have focused primarily upon the influence from family members to drink less. Those studies that have focused upon peer influence have been largely confined to social norms among adolescent and college-age drinkers. By contrast, based in adult populations, this article examines exhortations from friends not only to reduce alcohol consumption but also to increase it. Survey data in 15 countries that participate in the Gender, Alcohol and Culture: An International Study project (GENACIS) were used to test whether there were country and gender differences concerning the influence to drink less or to drink more by friends and examine if this was affected by the drinking behavior. The findings revealed that those influenced to drink less had more heavy episodic drinking (HED) occasions than those who did not report such influence. By contrast, influence to drink more, originating mainly from same-sex friends, may be more the result of social situations that encourage all drinkers, regardless of their frequency of HED occasions. At the country level, influence to drink less for both sexes decreased with the proportion of drinkers in a country. Similarly, influence to drink less for both sexes also decreased in countries where gender roles were more egalitarian. Thus, in countries where alcohol use is more widespread and fewer differences are observed between male and female gender role expectations, fewer people were influenced to drink less. These findings have implications for social and behavioral strategies designed to reduce alcohol-related harm across a wide range of cultures. Copyright © 2013 Elsevier Ltd. All rights reserved.

    We have studied the role of the immune response in the morphology of the leishmaniotic granuloma induced in the cheek pouch of hamsters, an immunologically privileged site, after inoculation of 3 x 10(5) Leishmania mexicana. Animals were histologically and immunologically evaluated until 120 days after inoculation. Independent of the time of sacrifice, the animals were always non-reactors to the footpad test (FPT). At histology, the introduction of L. mexicana in the cheek pouch leads to an abscess that evolves to a granulomatous reaction rich in amastigote forms, and later it leads to resolution, even in the absence of immune response detectable by FPT. Our results demonstrate that the development of immune response is not preponderant for the control of infection induced by L. mexicana inoculated subcutaneously in the cheek pouch of the hamster. It also suggests that the macrophages present in the leishmaniotic granuloma are capable of eliminating this parasite, even in the absence of immune response evaluated by FPT.

    This study proposes to implement an alternative and effective strategy for local treatment of disease provoked by S. aureus. For the analysis of possible anti-inflammatory activity of essential oil, after establishing an air pouch model, 48 male mice of Balb/c were treated, infected, and euthanized at 4 and 8 h. Thus, the total and differential white blood cells were counted in the animal's blood, and cytokines IL-1β, IL-6, and TNF-α were titrated using ELISA in the air pouch lavage. Moreover, TNF-α, IL-1β, and IL-6 gene expression was analyzed through an RT-qPCR array, and S. aureus was quantified using qPCR. Our results, p < 0.05, showed that EOC reduced the quantity of microorganisms. The group of mice treated with essential oil citral showed a significant decrease in TNF-α levels in tests demonstrating anti-inflammatory activity. There is no data about the mutual influence of the air pouch model, essential oil citral, and S. aureus. Thus, considering the interaction of these variables and the anti-inflammatory activity of the essential oil citral, we demonstrated, by alternative local treatment, a new antimicrobial agent that is not an antibiotic.

    2014-10-01

    Full Text Available In this paper, a novel concept of coupling the actuators of an automated order picking system for pouch packed goods with an embedded CCD camera sensor by means of image processing and machine learning is presented. The picking system mechanically combines the conveyance and singularization of a still-connected chain of pouch packed goods in a single machinery. The proposed algorithms perform a per-frame processing of the captured images in real-time to detect the sealed seams of the ongoing pouches. The detections are used to deduce cutting decisions in order to control the system’s actuators, namely the drive pulley for conveyance and the cutting device for the separation. Within this context, two controlling strategies are presented as well which specify the interaction of the sensor and the actuators. The detection is carried out by two different marker detection strategies: enhanced Template Matching as a heuristic and Support Vector Machines as a supervised classification based concept. Depending on the employed marker, detection rates of almost 100% with a calculation time of less than 40 ms are possible. From a logistic point of view, sealed seam widths of 20 mm prove feasible.

The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and modified connective tissue graft technique. In this randomized, double blind, parallel and prospective study, 40 non-smoker individuals with 40 class III alveolar ridge defects in maxillary anterior were randomly divided in two groups. Group I received modified connective tissue graft, while group II were treated with subepithelial connective tissue graft in pouch technique. The defect size was measured in its horizontal and vertical dimension by utilizing a periodontal probe in a stone cast at base line, after 3 months, and 6 months post surgically. Analysis of variance and Bonferroni post-hoc test were used for statistical analysis. A two-tailed P connective tissue graft proposed significantly more improvement as compare to connective tissue graft in pouch.

    Oral carcinoma accounts for 40-50 percent of all cancers in India. Tobacco chewing, smoking and alcohol consumption are the major risk factors associated with the high incidence of oral cancer in India. Our aim was to investigate the chemopreventive potential of curcumin and piperine during 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch carcinogenesis. Oral squamous cell carcinoma was developed in the buccal pouch of Syrian golden hamsters, by painting them with 0.5 percent DMBA in liquid paraffin, three times a week for 14 weeks. The tumour incidence, tumour volume and burden were determined in the buccal pouches. The status of phase II detoxification agents, lipid peroxidation and antioxidants were estimated by specific colorimetric methods. We observed 100 percent tumour formation in DMBA-alone painted hamsters. Disturbances in the status of lipid peroxidation, antioxidants and phase II detoxification agents were noticed in DMBA-alone painted hamsters. Oral administration of curcumin (80 mg/kg body weight) and piperine (50 mg/kg body weight) to DMBA-painted hamsters on alternate days to DMBA painting for 14 weeks completely prevented the formation of oral carcinoma. Also, curcumin and piperine restored the status of lipid peroxidation, antioxidants and detoxifying agents in DMBA-painted hamsters. The chemopreventive efficacy of curcumin and piperine is probably due to their antilipidperoxidative and antioxidant potential as well as their modulating effect on the carcinogen detoxification process.

    Extract of Ruscus aculeatus is used in treatment of venous insufficiency. In the present study, we used the hamster cheek pouch preparation and investigated in vivo the effects of an alpha 1 and alpha 2 adrenoceptor antagonists, a calcium blocker, Ruscus extract, and their combination on increased microvascular permeability induced by histamine. Experiments were performed on male hamsters; 30 min after completion of the cheek pouch preparation, fluorescein-labeled dextran (molecular weight 150,000) was given intravenously (i.v.). Histamine, applied topically, increased the number of fluorescent vascular leakage sites from postcapillary venules, evidence of an increase in macromolecular permeability, which was quantified by ultraviolet light microscopy as the number of leaky sites in the prepared area. Prazosin (alpha 1-adrenoceptor antagonist), diltiazem (calcium blocker), and Ruscus extract applied topically dose-dependently inhibited the macromolecular permeability-increasing effect of histamine. Rauwolscine (alpha 2-adrenoceptor antagonist), also applied topically, had no effect on histamine-induced permeability increase. Inhibition of the histamine-induced permeability increase evoked by Ruscus extract could be blocked by prazosin and by diltiazem but not by rauwolscine. These results indicate that any variation in the transmembrane flux of calcium impairs formation of microvascular leaky sites by histamine. Our results show that Ruscus extract has a protective effect against the leakage of FITC-dextran in hamster cheek pouch after administration of histamine that is modulated by calcium and selectively by alpha 1-adrenoceptors.

    Kheer, a traditional milk product of South East Asia, containing cooked rice grains in a creamy sweetened concentrated milk, has no large-scale production due to its poor shelf life. Shelf-life was improved by development of a process based on in-pouch thermal processing employing a rotary retort. Product development included optimization of rice-to-milk solids ratio (0.18-0.52) and total milk solids levels (16-26 %) to simulate the conventional product in taste, appearance and textural attributes. Various Fo values (12.4-14.8) were examined with regard to product quality. While the TBA value tended to increase (0.073-0.081) the reflectance value (35.3-43.4) declined with increasing Fo. The pH of the product (6.04-6.10) showed a slight tendency to increase with Fo. Sensorily, the product was found to be acceptable for a period of 150 days at 37 °C.

    This study was performed to examine the carcinogenic effects of benzo(a)pyrene (B(a)P) and manufactured gas plant (MGP) residues on the hamster cheek pouch (HCP). Syrian hamsters were treated topically with a suspension of 2%, 10%, or 20% B(a)P or 50% or 100% MGP-7 (a mixture of residues from 7 MGP sites) in mineral oil for eight (short-term study) and sixteen, twenty, twenty-eight, and thirty-two weeks (long-term study). The short-term study showed that B(a)P induced p53 protein accumulation, indicative of genotoxic damage, as well as increased cell proliferation, hyperplasia, and inflammation, which is usually associated with promotional activity. In contrast, the MGP-7 presented only marginal p53 accumulation and induction of BrdU incorporation. In the long-term experiments, animals treated with 2% and 10% of B(a)P continued to show p53 protein accumulation as well as hyperplasia and increased cell proliferation and inflammation. By thirty weeks, all the animals treated with B(a)P had a 100% incidence of squamous cell carcinoma (SCC). Animals treated with 50% and 100% MGP-7 showed only weak hyperplasia and a low proliferation rate and accumulation of p53 protein through thirty-two weeks. Benzo(a)pyrene was highly carcinogenic when used at adequate doses. Manufactured gas plant residue, however, was not carcinogenic in this model.

    The current lithium-ion battery technology is limited to about 250 Wh kg-1. In contrast the lithium-sulfur battery is expected to achieve more than 400 Wh kg-1 on cell level.[1,2] To date the biggest drawback of lithium- sulfur is its limited cycle stability of less than 200 cycles. Further, high energy densities can only be achieved if no excess of lithium and electrolyte is used and the areal loading of sulfur is high.[3]Here we demonstrate how the cycle stability can be extended to 1000 cycles using alternative silicon-carbon and all-carbon anodes instead of metallic lithium.[4] We also present a dry-processing technology for the sulfur cathode preparation. Besides no drying step and no toxic solvents, our process enables also twice the areal capacity (4-5 mAh cm-2) of slurry based technologies.[5] In addition we give results on the cycle stability and energy density of our lithium-sulfur pouch- cells (2.5+ Ah).

    Four formulas of canned tuna in spring water and tuna in mayonnaise and pouched tuna in salad cream and tuna in thousand island cream with added inulin were developed for commercial production. The effects of the addition of a prebiotic (inulin, Orafti®-HP) on the color and sensory properties of these products were studied. For inulin concentrations studied (3, 5, 7 and 10 %, w/w) caused more intensed yellow and red colors. Hedonic sensory values of tuna packed in spring water and in mayonnaise showed no significant differences (p > 0.05) among products with different inulin addition levels (3, 5, 7 and 10 %, w/w) in terms of color, flavor, sweetness and overall characteristics. However, when packed in thousand island cream, significant differences (p thousand island and tuna in salad cream, respectively. Considering formula cost in a commercial production and the recommended daily intake (RDI) of inulin in the finished product at end of shelf life (≥3 g/d), an addition of 5 % inulin for tuna in spring water and 7 % inulin for tuna in mayonnaise, tuna in thousand island and tuna in salad cream are recommended.

    Full Text Available Heme oxygenase-1 (HO-1 is induced by many stimuli to modulate the activation and function of different cell types during innate immune responses. Although HO-1 has shown anti-inflammatory effects in different systems, there are few data on the contribution of myeloid HO-1 and its role in inflammatory processes is not well understood. To address this point, we have used HO-1M-KO mice with myeloid-restricted deletion of HO-1 to specifically investigate its influence on the acute inflammatory response to zymosan in vivo. In the mouse air pouch model, we have shown an exacerbated inflammation in HO-1M-KO mice with increased neutrophil infiltration accompanied by high levels of inflammatory mediators such as interleukin-1β, tumor necrosis factor-α, and prostaglandin E2. The expression of the degradative enzyme matrix metalloproteinase-3 (MMP-3 was also enhanced. In addition, we observed higher levels of serum MMP-3 in HO-1M-KO mice compared with control mice, suggesting the presence of systemic inflammation. Altogether, these findings demonstrate that myeloid HO-1 plays an anti-inflammatory role in the acute response to zymosan in vivo and suggest the interest of this target to regulate inflammatory processes.

    There is a paucity of literature on the histopathological aspects of congenital pouch colon (CPC) and immunohistochemical (IHC) assessment has not been reported. So we planned to study the histopathological and IHC findings within the spectrum of CPC and compare the findings with the normal colon. This is a descriptive prospective study on CPC patients. There were 49 cases of CPC (42 males and 7 females) and 13 controls. Histological examination was done using hematoxylin and eosin and Masson trichrome stain. IHC analysis was done with actin, myosin, and desmin antibodies, and neuron-specific enolase and S100 markers for counting ganglionic cells. Histologically, congestion, edema and hemorrhage were seen in mucosa, submucosa, and serosa. Muscle layers were disrupted and divided into bands. An additional muscle coat inside of the muscularis propria was seen in CPC types 1 and 2. Mature ganglionic cells were reduced and muscle layers showed reduced and patchy positivity for smooth muscle actin, myosin, and desmin compared to a normal colon. Histopathological and IHC findings suggest that CPC has distinct defects in the neuromusculature. © 2017 S. Karger AG, Basel.

    Rheumatoid arthritis (RA) is one of several inflammatory and autoimmune diseases that affect approximately 1% of world's population. The development of TNF inhibitors in the last decade represents a great advance in the treatment of mild and severe forms of RA. Etanercept is one of these drugs that is useful for RA treatment, but the mechanism of inhibition of the signaling pathway of inflammation was not completely elucidated. This study was conducted to evaluate the anti-inflammatory effect of etanercept in comparison to reference drugs (dexamethasone and indomethacin). Inflammation was induced by subcutaneal administration of carrageenan in the Swiss albino mice using the murine air pouch model. Exudation; leukocytes; myeloperoxidase (MPO); adenosine deaminase (ADA); nitric oxide metabolites (NOx); tumor necrosis factor (TNF); interferon gamma (IFN-γ); interleukins (IL) IL-6, IL-17, IL-10, IL-4, and IL-2; nuclear transcription factor kappa B (NF-κB) activation and apoptosis were evaluated 24 h after the induction of inflammation. Treatment with etanercept significantly inhibited exudate concentrations; leukocyte count; MPO and ADA activities; NOx, TNF, IFN-γ, and IL-17 levels; and NF-kappa B activation (p Etanercept induced apoptosis, reducing the number of viable neutrophils without increasing necrosis (p etanercept may be via decrease of NF-κB activation. This effect promoted the reduction of pro-inflammatory cytokines and NOx and the induction of neutrophil apoptosis. The effect of etanercept upon neutrophils apoptosis may indicate the use of this drug therapy in the early stage of rheumatoid arthritis disease.

  15. Drinking water fluoridation and bone.

    Drinking water fluoridation has an established role in the prevention of dental caries, but may also positively or negatively affect bone. In bone fluoride is incorporated into hydroxylapatite to form the less soluble fluoroapatite. In higher concentrations fluoride stimulates osteoblast activity leading to an increase in cancellous bone mass. As optimal drinking water fluoridation (1 mg/l) is widely used, it is of great interest, whether long-term exposition to artificial water fluoridation has any impact on bone strength, bone mass, and -- most importantly -- fracture rate. Animal studies suggest a biphasic pattern of the effect of drinking water fluoridation on bone strength with a peak strength at a bone fluoride content of 1200 ppm followed by a decline at higher concentrations eventually leading to impaired bone quality. These changes are not paralleled by changes in bone mass suggesting that fluoride concentrations remain below the threshold level required for activation of osteoblast activity. Accordingly, in most epidemiological studies in humans bone mass was not altered by optimal drinking water fluoridation. In contrast, studies on the effect on hip fracture rate gave conflicting results ranging from an increased fracture incidence to no effect, and to a decreased fracture rate. As only ecological studies have been performed, they may be biased by unknown confounding factors -- the so-called ecological fallacy. However, the combined results of these studies indicate that any increase or decrease in fracture rate is likely to be small. It has been calculated that appropriately designed cohort studies to solve the problem require a sample size of >400,000 subjects. Such studies will not be performed in the foreseeable future. Future investigations in humans should, therefore, concentrate on the effect of long-term drinking water fluoridation on bone fluoride content and bone strength.

    Background Evidence suggests there are important sexual-orientation differences in alcohol consumption, particularly among women. Little is known about where gay/lesbian and bisexual college students drink or differences in patterns of alcohol use between heterosexual, gay/lesbian, and bisexual students. The goal of this analysis was to examine patterns of alcohol consumption—including drinking prevalence, quantity, frequency, and contexts of use—by sexual orientation. Methods Data on sexual identity, gender, drinking behaviors, and drinking contexts were examined from repeated cross-sectional samples of undergraduate students attending 14 public California universities from 2003–2011 (n=58,903). Multivariable statistical techniques were employed to examine sexual-orientation differences stratified by gender. Results Gay males, lesbians, and bisexual females were significantly more likely to report drinking alcohol in the current semester than their same-gender heterosexual peers (relative risks ranged from 1.07 to 1.10, p-values<0.01). Among current drinkers, bisexual females consumed 7 or more drinks and lesbians consumed 10 or more drinks on significantly more days than heterosexual females. On the other hand, gay male drinkers consumed 8 or more drinks on significantly fewer days than heterosexual male drinkers. Compared to their same-gender heterosexual peers: lesbian/gay and bisexual students drank less frequently at Greek parties (incidence rate ratios [IRRs] ranged from 0.52 to 0.73, p-values<0.01); lesbians (IRR=0.84, p=0.043) and bisexual males (IRR=0.82, p=0.009) drank less frequently at off-campus parties; and gay males drank more frequently outdoors (IRR=1.63, p<0.001) and at bars/restaurants (IRR=1.21, p=0.013). Conclusions Alcohol prevention programs and future research should consider sexual-orientation differences in drinking patterns and drinking contexts. PMID:26827292

    Oral mucositis induced by radiotherapy impacts quality of life. Previous studies have reported on the use of the hamster as a model for radiation-induced oral mucositis; however, details regarding factors such as radiation dose response, effects on myeloperoxidase (MPO) activity and related histopathological changes remain unclear. In the present study using the hamster, we evaluated the dose dependency of radiation-induced oral mucositis and the effects of keratinocyte growth factor (palifermin). Oral mucositis was induced in the cheek pouch by X-irradiation using single doses in the range 20-50 Gy. To evaluate the protective effect of palifermin, administration was carried out (5 mg/kg) on days 1, 2 and 3 or on days 9, 10 and 11 after single irradiation at a dose of 40 Gy. The oral mucositis score, MPO activity and histopathological findings of inflammation increased in a dose dependent manner. Palifermin treatment stimulated the proliferation of mucosal epithelial cells. Additionally, palifermin when administered on days 1, 2 and 3 after irradiation (40 Gy) reduced the severity of oral mucositis. The hamster was found to be a suitable model for radiation-induced oral mucositis, with excellent results regarding the evaluation of radiation dose response and drug reactivity.

    Chemical analyses of organic residues in fragments of pottery from the large site of Cahokia and surrounding smaller sites in Illinois reveal theobromine, caffeine, and ursolic acid, biomarkers for species of Ilex (holly) used to prepare the ritually important Black Drink. As recorded during the historic period, men consumed Black Drink in portions of the American Southeast for ritual purification. This first demonstrated discovery of biomarkers for Ilex occurs in beaker vessels dating between A.D. 1050 and 1250 from Cahokia, located far north of the known range of the holly species used to prepare Black Drink during historic times. The association of Ilex and beaker vessels indicates a sustained ritual consumption of a caffeine-laced drink made from the leaves of plants grown in the southern United States. PMID:22869743

    Several different mechanisms have been proposed to account for the consistent but moderate inverse relationship between religiosity and drinking, ranging from the direct proscriptions against alcohol in various faiths to social learning based on parental upbringing. Alcohol expectancies and drinking motives may be more proximal cognitive mechanisms that influence this relationship. The present study, using 265 college undergraduates, gathered self-report data using the Comprehensive Effects of Alcohol questionnaire, the Drinking Motives Questionnaire-Revised and the Religious Orientation Scale-Revised. Of religiosity measures, intrinsic religiosity most closely related to quantity of alcohol consumption. Participants in conservative religious denominations had higher negative expectancies and lower drinking motives. Several positive and negative expectancies as well as drinking motives partially mediated the relationship between intrinsic religiosity and alcohol consumption. These results suggest that individuals' religious beliefs have influences on their alcohol consumption through several separate mechanisms. Religiosity may have direct effects that reduce drinking, as well as indirect effects via expectancies and motivations to drink. Negative expectancies, in particular, may serve as a buffer to promote abstinence and to reduce drinking in individuals with greater religiosity.

    Oral cancers suffer from poor 5-year survival rates, owing to late detection of the disease. Current diagnostic/screening tools need to be upgraded in view of disadvantages like invasiveness, tedious sample preparation, long output times, and interobserver variances. Raman spectroscopy has been shown to identify many disease conditions, including oral cancers, from healthy conditions. Further studies in exploring sequential changes in oral carcinogenesis are warranted. In this Raman spectroscopy study, sequential progression in experimental oral carcinogenesis in Hamster buccal pouch model was investigated using 3 approaches-ex vivo, in vivo sequential, and in vivo follow-up. In all these studies, spectral changes show lipid dominance in early stages while later stages and tumors showed increased protein to lipid ratio and nucleic acids. On similar lines, early weeks of 7,12-dimethylbenz(a)anthracene-treated and control groups showed higher overlap and low classification. The classification efficiency increased progressively, reached a plateau phase and subsequently increased up to 100% by 14 weeks. The misclassifications between treated and control spectra suggested some changes in controls as well, which was confirmed by a careful reexamination of histopathological slides. These findings suggests Raman spectroscopy may be able to identify microheterogeneity, which may often go unnoticed in conventional biochemistry wherein tissue extracts are employed, as well as in histopathology. In vivo findings, quite comparable to gold-standard supported ex vivo findings, give further proof of Raman spectroscopy being a promising label-free, noninvasive diagnostic adjunct for future clinical applications. © The Author(s) 2015.

    Members of the family Gastrothylacidae (Trematoda: Digenea: Paramphistomata) are parasitic in ruminants throughout Africa and Asia. In north-east India, five species of pouched amphistomes, namely Fischoederius cobboldi, F. elongatus, Gastrothylax crumenifer, Carmyerius spatiosus and Velasquezotrema tripurensis, belonging to this family have been reported so far. In the present study, the molecular phylogeny of these five gastrothylacid species is derived using the second internal transcribed spacer (ITS2) sequence and secondary structure analyses. ITS2 sequence analysis was carried out to see the occurrence of interspecific variations among the species. Phylogenetic analyses were performed for primary sequence data alone as well as the combined sequence-structure information using neighbour-joining and Bayesian approaches. The sequence analysis revealed that there exist considerable interspecific variations among the various gastrothylacid fluke species. In contrast, the inferred secondary structures for the five species using minimum free energy modelling showed structural identities, in conformity with the core four-helix domain structure that has been recently identified as common to almost all eukaryotic taxa. The phylogenetic tree reconstructed using combined sequence-structure data showed a better resolution, as compared to the one using sequence data alone, with the gastrothylacid species forming a monophyletic group that is well separated from members of the other family, Paramphistomidae, of the amphistomid flukes group. The study provides the molecular characterization based on primary sequence data of the rDNA ITS2 region of the gastrothylacid amphistome flukes. Results also demonstrate the phylogenetic utility of the ITS2 sequence-secondary structure data for inferences at higher taxonomic levels.

    Women with ulcerative colitis (UC), who require ileal pouch anal anastomosis (IPAA), have up to a threefold increased incidence of infertility. To better counsel patients who require colectomy, we examined the success rates of in vitro fertilization (IVF) among women who have undergone IPAA. This was a retrospective cohort study conducted at the Brigham and Women's Hospital and Beth Israel Deaconess Medical Center. Female patients with UC were identified via ICD-9 codes and cross-referenced with those presenting for IVF from 1998 through 2011. UC patients with IPAA were compared with the following two unexposed groups that underwent IVF: (1) patients with UC, who had not undergone IPAA, and (2) patients without inflammatory bowel disease (IBD). The primary outcome was the cumulative live birth rate. Secondary outcomes included number of oocytes retrieved, proportion of patients who underwent embryo transfer, pregnancy rate, and live birth rate at first cycle. There were 22 patients with UC and IPAA, 49 patients with UC and without IPAA, and 470 patients without IBD. The cumulative live birth rate after six cycles in the UC and IPAA groups was 64% (95% confidence interval (CI): 44-83%). This rate did not differ from the cumulative live birth rate in the UC without IPAA group (71%, 95% CI: 59-83%; P=0.63) or the group without IBD (53%, 95% CI: 48-57%; P=0.57). This study demonstrates that in our cohort, women who undergo IPAA achieve live births following IVF at comparable rates to women with UC without IPAA and to women without IBD.

    The aim of this review is to determine the effect of ileal pouch-anal anastomosis (IPAA) on female fertility in ulcerative colitis (UC) and familial adenomatous polyposis (FAP), the mechanisms of this effect, strategies for prevention and management of infertility post-IPAA. This paper is a systematic literature review of all articles investigating IPAA and fertility from 1966 onwards that were found searching the Medline and Embase databases. Meta-analysis was performed on relevant studies. Seventeen relevant studies were identified. Six studies were excluded (duplicate data, one; predominantly not IPAA patients, one; no control group, four). The control groups of the remaining 11 studies were too varied for comparison, and so the meta-analysis was limited to six studies that provided data on infertility both pre- and post-IPAA. Five of these involved predominantly UC patients and one FAP. Average infertility rates were 20% pre-IPAA and 63% post-IPAA. The relative risk of infertility after IPAA is 3.91 ([2.06, 7.44] 95% CI). The possibility of publication bias suggests that the risk may be lower. Any increased risk is probably due to tubal dysfunction secondary to adhesions. Various methods have been proposed to reduce pelvic adhesions, but there is no evidence they have any effect in preventing infertility. Infertility treatment post-IPAA is associated with good success rates. Infertility is increased after IPAA in female patients in both UC and FAP. Both these disease processes affect patients during their reproductive years. This evidence emphasizes the need for careful consideration of fertility in the choice and timing of surgery.

    Ileal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. All UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. A total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). In this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA. Copyright © 2016 Elsevier Inc. All rights reserved.

  11. Vimentin and laminin are altered on cheek pouch microvessels of streptozotocin-induced diabetic hamsters

    Full Text Available OBJECTIVE: Normal endothelial cells respond to shear stress by elongating and aligning in the direction of fluid flow. Hyperglycemia impairs this response and contributes to microvascular complications, which result in deleterious effects to the endothelium. This work aimed to evaluate cheek pouch microvessel morphological characteristics, reactivity, permeability, and expression of cytoskeleton and extracellular matrix components in hamsters after the induction of diabetes with streptozotocin. METHODS: Syrian golden hamsters (90-130 g were injected with streptozotocin (50 mg/kg, i.p. or vehicle either 6 (the diabetes mellitus 6 group or 15 (the diabetes mellitus 15 group days before the experiment. Vascular dimensions and density per area of vessels were determined by morphometric and stereological measurements. Changes in blood flow were measured in response to acetylcholine, and plasma extravasation was measured by the number of leakage sites. Actin, talin, α-smooth muscle actin, vimentin, type IV collagen, and laminin were detected by immunohistochemistry and assessed through a semiquantitative scoring system. RESULTS: There were no major alterations in the lumen, wall diameters, or densities of the examined vessels. Likewise, vascular reactivity and permeability were not altered by diabetes. The arterioles demonstrated increased immunoreactivity to vimentin and laminin in the diabetes mellitus 6 and diabetes mellitus 15 groups. DISCUSSION: Antibodies against laminin and vimentin inhibit branching morphogenesis in vitro. Therefore, laminin and vimentin participating in the structure of the focal adhesion may play a role in angiogenesis. CONCLUSIONS: Our results indicated the existence of changes related to cell-matrix interactions, which may contribute to the pathological remodeling that was already underway one week after induction of experimental diabetes.

    2015-01-01

    Accounts of drinking water-borne disease outbreaks have always captured the interest of the public, elected and health officials, and the media. During the twentieth century, the drinking water community and public health organizations have endeavored to craft regulations and guidelines on treatment and management practices that reduce risks from drinking water, specifically human pathogens. During this period there also evolved misunderstandings as to potential health risk associated with microorganisms that may be present in drinking waters. These misunderstanding or "myths" have led to confusion among the many stakeholders. The purpose of this article is to provide a scientific- and clinically-based discussion of these "myths" and recommendations for better ensuring the microbial safety of drinking water and valid public health decisions.

    Annual nationwide exposure maps for nitrate in drinking water in Denmark from the 1970s until today will be presented based on the findings in Schullehner & Hansen (2014) and additional work on addressing the issue of private well users and estimating missing data. Drinking water supply in Denmark...... is highly decentralized and fully relying on simple treated groundwater. At the same time, Denmark has an intensive agriculture, making groundwater resources prone to nitrate pollution. Drinking water quality data covering the entire country for over 35 years are registered in the public database Jupiter....... In order to create annual maps of drinking water quality, these data had to be linked to 2,852 water supply areas, which were for the first time digitized, collected in one dataset and connected to the Jupiter database. Analyses of the drinking water quality maps showed that public water supplies...

    We report two cases of ileoanal J-pouch rupture after rapid consumption of high-fiber, high-calorie meals. We review the food intake, presentation, laboratory and radiographic data, and course of two patients who developed ileoanal J-pouch perforation after rapid consumption of meals rich in fiber or calories or both. The potential association between food consumption and rupture is explored. The authors propose that the rapid ingestion of a high-fiber, high-calorie meal may lead to an acute intraluminal pressure elevation or a closed-loop obstruction. These effects may be the basis for an association between food ingestion patterns and perforation at the distal transection site in an ileoanal J-pouch. The authors hypothesize that the rapid ingestion of a high-fiber, high-calorie meal may be associated with J-pouch perforation. Further investigative efforts are needed to confirm this association and to evaluate whether a causal relationship is present. If causality is established, physicians may develop a higher index of suspicion for pouch rupture in patients who present with abdominal disturbances after the rapid ingestion of a high-fiber, high-calorie meal.

    Negative drinking consequences in college students have been well studied, but emerging evidence points to a role for positive drinking consequences in predicting alcohol related problems. Positive drinking consequences appear to be distinct from other drinking constructs such as drinking expectancies and drinking motives. However, no work has evaluated the role of positive drinking consequences in hazardous drinking college students, a population at high risk for alcohol related problems. The goal of the current study was to examine the effect of positive drinking consequences on problem drinking and alcohol problem recognition in a hazardous drinking college sample. Participants (N=222) were hazardous drinking undergraduate students completing a battery of self-report measures about alcohol use. Findings indicated that positive drinking consequences predicted problem drinking above and beyond other related constructs including positive drinking motives (i.e. enhancement and social). However, positive drinking consequences did not appear to play a significant role in alcohol problem recognition. Future research directions and implications for interventions with hazardous drinking college students are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The impact of caffeine from energy drinks occurs against a background exposure from naturally occurring caffeine (coffee, tea, cocoa and foods containing these ingredients) and caffeinated beverages (kola-type soft drinks). Background caffeine exposure, excluding energy drinks, was assessed for six New Zealand population groups aged 15 years and over (n = 4503) by combining concentration data for 53 caffeine-containing foods with consumption information from the 2008/09 New Zealand Adult Nutrition Survey (ANS). Caffeine exposure for those who consumed energy drinks (n = 138) was similarly assessed, with inclusion of energy drinks. Forty-seven energy drink products were identified on the New Zealand market in 2010. Product volumes ranged from 30 to 600 ml per unit, resulting in exposures of 10-300 mg caffeine per retail unit consumed. A small percentage, 3.1%, of New Zealanders reported consuming energy drinks, with most energy drink consumers (110/138) drinking one serving per 24 h. The maximum number of energy drinks consumed per 24 h was 14 (total caffeine of 390 mg). A high degree of brand loyalty was evident. Since only a minor proportion of New Zealanders reported consuming energy drinks, a greater number of New Zealanders exceeded a potentially adverse effect level (AEL) of 3 mg kg(-1) bw day(-1) for caffeine from caffeine-containing foods than from energy drinks. Energy drink consumption is not a risk at a population level because of the low prevalence of consumption. At an individual level, however, teenagers, adults (20-64 years) and females (16-44 years) were more likely to exceed the AEL by consuming energy drinks in combination with caffeine-containing foods.

    Full Text Available Abstract Background To evaluate the relative chemopreventive efficacy of two black tea polyphenols, Polyphenon-B [P-B] and BTF-35 on 7,12-dimethylbenz [a]anthracene (DMBA-induced hamster buccal pouch (HBP carcinogenesis. Methods Hamsters were divided into 6 groups. The right buccal pouches of animals in groups 1–3 were painted with 0.5% of DMBA three times a week for 14 weeks. While hamsters in group 1 received no further treatment, animals in groups 2 and 3 received diet containing 0.05% P-B and BTF-35 respectively, four weeks before DMBA painting that was continued until the end of the experiments. Animals in groups 4 and 5 were given P-B and BTF-35 alone respectively as in groups 2 and 3. Group 6 animals served as the untreated control. All the animals were sacrificed after 18 weeks. The expression of p21, cyclin D1, glutathione S-transferase pi (GST-P, nuclear factor kappa B (NF-κB, Bcl-2, Bax, cytochrome C, caspase-3, caspase-9, poly(ADP-ribose polymerase (PARP, cytokeratins and vascular endothelial growth factor (VEGF was analysed by RT-PCR, immunohistochemical and Western blot analyses. Results DMBA treated animals developed buccal pouch carcinomas that displayed increased expression of p21, cyclin D1, GST-P, NF-κB, cytokeratins, VEGF and Bcl-2 with decreased expression of Bax, cytochrome C, caspase-3, caspase-9, and PARP. Dietary administration of both P-B and BTF-35 reduced the incidence of DMBA-induced HBP carcinomas by modulating markers of cell proliferation, cell survival, tumour infiltration, angiogenesis, and apoptosis. Conclusion The results of the present study provide a mechanistic basis for the chemopreventive potential of black tea polyphenols. The greater efficacy of BTF-35 in inhibiting HBP carcinogenesis and modulating multiple molecular targets may have a potential role in the prevention of oral cancer.

    Full Text Available Ready-to-eat fruits packed in sealed containers are highly perishable due to their intrinsic characteristics and lack of full thermal process. Ohmic heating has the advantages of rapid liquid heating through electrical current. The aim of this research was to investigate the effect of indirect ohmic heating on pH, total soluble solids, polyphenol oxidase activity, color and texture of ready-to-eat pineapple packed in a polypropylene pouch with 1% calcium chloride and 0.3% ascorbic acid packing solution. The pre-packed sample in a pouch was placed in the ohmic heating jar filled with 0.5% sodium chloride ohmic heating solution which was then ohmic heated at different voltage gradients (20, 30, 40 V/cm, to different packing solution temperatures (60, 70, 80°C for 60s. Samples were kept at 4°C for quality measurement. It was found that browning index of ready-to-eat pineapple treated with 20 V/cm at 80°C, 30 V/cm at 70°C and 80°C, 40 V/cm at 80°C did not change during 12 days cold storage (p>0.05. Polyphenol oxidase was inactivated when the temperature of the pineapple was 62°C or higher. After 10 days at 4°C, the pineapple heated with 30 V/cm at 70°C had much higher firmness than the un-heated sample kept at the same storage condition. Indirect ohmic heating of pre-packed ready-to-eat pineapple in polypropylene pouch with 30 V/cm at 70°C packing solution temperature for 60s could be used as minimal heating methods to maintain the quality of ready-to-eat fruits in 12 days at 4°C.

    Full Text Available The role of resident cells during the lipopolysaccharide (LPS-induced neutrophil recruitment into rat air pouches was investigated. In this model, LPS (Escherichia coli, O55: B5 strain; 2–2000 ng induced a dose– and time-dependent neutrophil recruitment accompanied by the generation of a tumour necrosis factor-α (TNFα-like activity. Dexamethasone (0.05–5 mug and cycloheximide (6 ng, injected 2 h before LPS into the pouches, inhibited the neutrophil recruitment and the generation of the TNFα-like activity, while the H1-receptor antagonist mepyramine (1 and 4 mg/kg, i.p., 0.5 h before LPS and the PAF-receptor antagonist WEB 2170 (0.05 and 1 mg/kg, i.p., 0.5 h before LPS had no effect. Purified alveolar macrophages (AM were used to replenish the pouches of cycloheximide-treated recipient rats. AM provided by PBS-treated animals led to the recovery of the LPS-induced neutrophil recruitment and of the TNFα-like formation contrasting with those from cycloheximide-treated animals (1 mg/kg, i.p.. When delivered in situ, liposome-encapsulated clodronate, a macrophage depletor, significantly impaired both the LPSinduced neutrophil recruitment and the TNFα-like activity. An anti-murine TNFα polyclonal antibody (0.5 h before LPS was also effective. These results emphasize the pivotal role of macrophages for LPS-induced neutrophil recruitment via the formation of TNFα.

    Full Text Available Background: Localized alveolar ridge defect may create physiological and pathological problems. Developments in surgical techniques have made it simpler to change the configuration of a ridge to create a more aesthetic and more easily cleansable shape. The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and modified connective tissue graft technique. Materials and Methods: In this randomized, double blind, parallel and prospective study, 40 non-smoker individuals with 40 class III alveolar ridge defects in maxillary anterior were randomly divided in two groups. Group I received modified connective tissue graft, while group II were treated with subepithelial connective tissue graft in pouch technique. The defect size was measured in its horizontal and vertical dimension by utilizing a periodontal probe in a stone cast at base line, after 3 months, and 6 months post surgically. Analysis of variance and Bonferroni post-hoc test were used for statistical analysis. A two-tailed P < 0.05 was considered to be statistically significant. Results: Mean values in horizontal width after 6 months were 4.70 ± 0.87 mm, and 4.05 ± 0.89 mm for group I and II, respectively. Regarding vertical heights, obtained mean values were 4.75 ± 0.97 mm and 3.70 ± 0.92 mm for group I and group II, respectively. Conclusion: Within the limitations of this study, connective tissue graft proposed significantly more improvement as compare to connective tissue graft in pouch.

    2014-01-01

    Background: We report a case of a neonate with proximal spinal muscular atrophy (SMA) type 1 (also known as Werdnig-Hoffmann disease or severe infantile acute SMA) associated with a Blake's pouch cyst; a malformation that is currently classified within the spectrum of Dandy-Walker complex. The association of the two conditions has not been previously reported in the English literature. A comprehensive review of the pertinent literature is presented. Case Description: A male neonate was noted to have paucity of movement of the four limbs with difficulty of breathing and poor feeding soon after birth. Respiratory distress with tachypnea, necessitated endotracheal intubation and mechanical ventilation. Pregnancy was uneventful except for decreased fetal movements reported by the mother during the third trimester. Neurological examination revealed generalized hypotonia with decreased muscle power of all limbs, nonelicitable deep tendon jerks, and occasional tongue fasciculations. Molecular genetic evaluation revealed a homozygous deletion of both exons 7 and 8 of the survival motor neuron 1 (SMN1) gene, and exon 5 of the neuronal apoptosis inhibitory protein (NAIP) gene on the long arm of chromosome 5 consistent with Werdnig-Hoffmann disease (SMA type 1). At the age of 5 months, a full anterior fontanelle and abnormal increase of the occipito-frontal circumference were noted. Computed tomographic (CT) scan and magnetic resonance imaging (MRI) of the brain revealed a tetraventricular hydrocephalus and features of Blake's pouch cyst of the fourth ventricle. Conclusions: This case represents a previously unreported association of Blake's pouch cyst and SMA type 1. PMID:25225621

    Sodium mercaptoundecahydro-closo-dodecaborate (BSH) is being investigated clinically for BNCT. We examined the biodistribution of BSH and BPA administered jointly in different proportions in the hamster cheek pouch oral cancer model. The 3 assayed protocols were non-toxic, and showed preferential tumor boron uptake versus precancerous and normal tissue and therapeutic tumor boron concentration values (70–85 ppm). All 3 protocols warrant assessment in BNCT studies to contribute to the knowledge of (BSH+BPA)-BNCT radiobiology for head and neck cancer and optimize therapeutic efficacy.

    Full Text Available Purpose- The aim of this paper is to review and reflect on the sustainability agendas and achievements reported by Europe's leading food and drinks wholesalers. Design/Methodology/Approach- The paper begins with a short introduction to corporate sustainability, sustainability reporting and food and drinks wholesaling within Europe and the empirical material for the paper is drawn from reports and information posted on the leading food and drinks wholesalers' corporate websites. Findings- There are marked variations in the extent to which Europe's leading food and drinks wholesalers reported and provided information on their sustainability agendas and achievements. These agendas and achievements embraced a wide range of environmental, social and economic issues but the reporting process had a number of weaknesses that undermine its transparency and credibility. The authors also argue that the leading food and drinks wholesalers' definitions of, and commitments to, sustainability are principally driven by business imperatives as by any fundamental concern to maintain the viability and integrity of natural and social capital. More critically the authors argue that this approach is couched within existing business models centred on continuing growth and consumption Limitations- The paper is a preliminary review of the sustainability agendas and achievements publicly reported by Europe's leading food and drinks wholesalers. Originality- The role of Europe's wholesale sector in addressing sustainability has received scant attention in the academic literature and this paper will interest academics and students in business management and marketing and employees and executives working in the distribution sector of the economy.

  5. Toxicity of energy drinks.

    2012-04-01

    'Energy drinks', 'energy shots' and other energy products have exploded in popularity in the past several years; however, their use is not without risk. Caffeine is the main active ingredient in energy drinks, and excessive consumption may acutely cause caffeine intoxication, resulting in tachycardia, vomiting, cardiac arrhythmias, seizures, and death. The effects of chronic high-dose caffeine intake in children and adolescents are unknown. Caffeine may raise blood pressure, disrupt adolescent sleep patterns, exacerbate psychiatric disease, cause physiologic dependence, and increase the risk of subsequent addiction. Coingestion of caffeine and ethanol has been associated with increased risk-taking behaviors, harm to adolescent users, impaired driving, and increased use of other illicit substances. The toxicity of ingredients often present in energy drinks, such as taurine, niacin, and pyridoxine, is less well defined. Recent and significant literature describing adverse events associated with energy drink use are reviewed. Although prior studies have examined the effects of caffeine in adolescents, energy drinks should be considered a novel exposure. The high doses of caffeine, often in combination with ingredients with unknown safety profiles, mandates urgent research on the safety of energy drink use in children and adolescents. Regulation of pediatric energy drink use may be a necessary step once the health effects are further characterized.

    The characteristics of ammonia in drinking water sources in China were evaluated during 2005-2009. The spatial distribution and seasonal changes of ammonia in different types of drinking water sources of 22 provinces, 5 autonomous regions and 4 municipalities were investigated. The levels of ammonia in drinking water sources follow the order of river > lake/reservoir > groundwater. The levels of ammonia concentration in river sources gradually decreased from 2005 to 2008, while no obvious change was observed in the lakes/reservoirs and groundwater drinking water sources. The proportion of the type of drinking water sources is different in different regions. In river drinking water sources, the ammonia level was varied in different regions and changed seasonally. The highest value and wide range of annual ammonia was found in South East region, while the lowest value was found in Southwest region. In lake/reservoir drinking water sources, the ammonia levels were not varied obviously in different regions. In underground drinking water sources, the ammonia levels were varied obviously in different regions due to the geological permeability and the natural features of regions. In the drinking water sources with higher ammonia levels, there are enterprises and wastewater drainages in the protected areas of the drinking water sources.

    Poor pouch function after restorative proctocolectomy for ulcerative colitis is a considerable problem. Pouchitis and functional disorders are the most common reasons. Probiotics seem to have a beneficial effect in pouchitis but have not been assessed in functional pouch disorders. The aim was to analyse the effects of probiotics in patients with poor pouch function. Thirty-three patients were randomized to probiotics (Lactobacillus plantarum 299 and Bifidobacterium infantis Cure 21) or placebo in a double blinded, 1:1 fashion. The treatment effect was assessed by the pouch functional score (PFS; 0-15, 15 worst), pouchitis disease activity index (PDAI; 0-18, 18 worst), and levels of four faecal biomarkers of inflammation (calprotectin, lactoferrin, myeloperoxidase [MPO] and eosinophilic cationic protein [ECP]). Thirty-two patients were included (probiotics = 17, placebo = 16). There was no difference in change in the PFS from before to after treatment between the groups (median difference: -1.00, 95% C.I. -3.00 to 0.00, p = 0.119). Furthermore, probiotics had no effect on PDAI (median difference: 0.00, 95% C.I. 0.00-1.00, p = 0.786), or on faecal biomarkers. Significant correlations were observed between PDAI and each of the faecal biomarkers at study start. There were no correlations between PFS or PDAI symptom subscore and the biomarkers. PDAI endoscopic and histologic subscores correlated significantly to each of the biomarkers. The hypothesis that probiotics improves pouch-related dysfunction was not confirmed. Faecal biomarkers could play a future role in the management of pouch patients.

  9. Drinking motives as mediators of social anxiety and hazardous drinking among college students.

    2009-01-01

    Although social anxiety (SA) and alcohol use disorders commonly co-occur, the relationship between these variables in college populations has been inconsistent. The present study tested the hypothesized model that negatively reinforcing, but not positively reinforcing, drinking motives (or reasons for drinking) would mediate the association between SA and three aspects of hazardous drinking (quantity/frequency, consequences, and dependence symptoms) in an ethnically diverse sample of college drinkers (N = 817; mean age = 19.9 years, range = 18-29). Structural equation modeling (SEM) results using the asymmetrical distribution of products test indicated that coping motives partially mediated the relationship between SA and negative consequences and dependence symptoms but not the quantity/frequency outcome. Contrary to the hypothesized model, conformity motives did not mediate the association between SA and hazardous drinking. As expected, positive reinforcement motives did not mediate the SA-hazardous drinking association. Multigroup SEM analyses revealed that the mediation models did not differ for men (n = 215) and women (n = 602). Overall, the present findings support extant research and theoretical models regarding the mediating role of coping motives in the relationship between SA and problem drinking, suggesting a potential pathway for the development and maintenance of SA and alcohol use disorder comorbidity. Such findings could contribute to improved intervention programs by targeting coping drinking motives and building coping skills.

    Research suggests that enhancement, conformity, social, coping-with-anxiety, and coping-with-depression drinking motives are linked to specific drinking outcomes in a theoretically expected manner. Social learning theory suggests that people who spend more time together emulate each other's behavior to acquire reinforcing outcomes. The present study sought to integrate drinking motives theory and social learning theory to investigate similarity in drinking behaviors and drinking motives in romantic couples. We hypothesized that couples would be more similar than chance in their drinking behaviors and motives. We also hypothesized that demographics reflecting time around and interactions with romantic partners (e.g., days spent drinking together) would positively correlate with similarity in drinking behaviors and motivations. The present study tested hypotheses in 203 romantic couples. Participants completed a Timeline Follow-Back measure and the Modified Drinking Motives Questionnaire-Revised to track their alcohol use and drinking motives. Similarity profiles were calculated using McCrae's (J Pers Assess. 2008;90:105-109) coefficient of profile agreement, rpa. Couples were more similar in their drinking behavioral and motivational profiles than could be explained by chance. Days spent drinking together and days with face-to-face contact predicted increased similarity in drinking behavior profiles, but not similarity in drinking motives profiles. Results are partially consistent with social learning theory and suggest that social influences within couples could be important intervention targets to prevent escalations in drinking.

    Full Text Available Chlorophyllin (CHL, a water-soluble, semi-synthetic derivative of chlorophyll and ellagic acid (EA, a naturally occurring polyphenolic compound in berries, grapes, and nuts have been reported to exert anticancer effects in various human cancer cell lines and in animal tumour models. The present study was undertaken to examine the mechanism underlying chemoprevention and changes in gene expression pattern induced by dietary supplementation of chlorophyllin and ellagic acid in the 7,12-dimethylbenz[a]anthracene (DMBA-induced hamster buccal pouch (HBP carcinogenesis model by whole genome profiling using pangenomic microarrays. In hamsters painted with DMBA, the expression of 1,700 genes was found to be altered significantly relative to control. Dietary supplementation of chlorophyllin and ellagic acid modulated the expression profiles of 104 and 37 genes respectively. Microarray analysis also revealed changes in the expression of TGFβ receptors, NF-κB, cyclin D1, and matrix metalloproteinases (MMPs that may play a crucial role in the transformation of the normal buccal pouch to a malignant phenotype. This gene expression signature was altered on treatment with chlorophyllin and ellagic acid. Our study has also revealed patterns of gene expression signature specific for chlorophyllin and ellagic acid exposure. Thus dietary chlorophyllin and ellagic acid that can reverse gene expression signature associated with carcinogenesis are novel candidates for cancer prevention and therapy.

    Full Text Available The study was carried out to provide the basic histology of submandubular salivary gland in the giant pouched rat, as there is dearth of information of its microscopic architecture in available literature. This becomes more important as the possible use of this species of rodent is considered as a future laboratory animal of choice over the Winster rat because of its bigger size and possibility of the giant pouched rat domestication as a ready source of animal protein. Hence the need to understand the digestive biology to help animal nutritionist in feed formulation. The histology revealed the presence of both serous and mucus secretory acini. Some mucus cell presented serous demilumes. Myoeithelial cells were seen around secretory cells and the intercalated ducts. The serous gland region with more relatively profuse intralobular ducts was larger in size than the mucus gland region. The intralobular ducts of intercalated and striated ducts were lined by simple cuboidal and simple columnar cells respectively. The excretory duct was line by stratified cuboidal cells. The large serous glandular region reflects need for more enzymic action in the oral cavity while the mucus glands will help produce mucin that will lubricate the digestive tract. This study for the first time documents the normal histology of submandibular salivary gland in this species, hence filling the knowledge gap that will help further investigative research especially the role of myoepihelial cells in secretory glands tumours.

    In this study we use a multi-spectral digital microscope (MDM) to measure multi-spectral auto-fluorescence and reflectance images of the hamster cheek pouch model of DMBA (dimethylbenz[α]anthracene)- induced oral carcinogenesis. The multi-spectral images are analyzed both in the RGB (red, green, blue) color space as well as in the YCbCr (luminance, chromatic minus blue, chromatic minus red) color space. Mean image intensity, standard deviation, skewness, and kurtosis are selected as features to design a classification algorithm to discriminate normal mucosa from neoplastic tissue. The best diagnostic performance is achieved using features extracted from the YCbCr space, indicating the importance of chromatic information for classification. A sensitivity of 96% and a specificity of 84% were achieved in separating normal from abnormal cheek pouch lesions. The results of this study suggest that a simple and inexpensive MDM has the potential to provide a cost-effective and accurate alternative to standard white light endoscopy.

    This study aims to explore the correlations between electrolyte volume, electrochemical performance, and properties of the solid electrolyte interphase in pouch cells with Si-graphite composite anodes. The electrolyte is 1.2 M LiPF6 in ethylene carbonate:ethylmethyl carbonate with 10 wt % fluoroethylene carbonate. Single layer pouch cells (100 mA h) were constructed with 15 wt % Si-graphite/LiNi0.5Mn0.3CO0.2O2 electrodes. It is found that a minimum electrolyte volume factor of 3.1 times to the total pore volume of cell components (cathode, anode, and separator) is needed for better cycling stability. Less electrolyte causes increases in ohmic and charge transfer resistances. Lithium dendrites are observed when the electrolyte volume factor is low. The resistances from the anodes become significant as the cells are discharged. Solid electrolyte interphase thickness grows as the electrolyte volume factor increases and is nonuniform after cycling.

    An outdoor test was conducted to evaluate initial efficacy and longevity of water-soluble pouches of Bacillus sphaericus (VectoLex WSP and VBC60035 WSP), applied as prehatch treatment against Culex species in simulated catch basins. Both VectoLex WSP and VBC60035 WSP, applied at 1 pouch (10 g) per basin (single treatment), yielded significant immediate and long-term (> 90% for 203 days) control of late instars of Culex mosquitoes. Consistent and complete control of pupae (100%) as a result of larval mortality was clearly indicated for 70 days posttreatment. Control levels varied but remained high and significant on most sampling days afterwards. Exuviae counts also indicated complete control (100%) for 70 days posttreatment. Control levels indicated by exuviae counts, however, were not significant for most sampling days beyond this sampling day, because of low counts in the untreated controls. No significant differences were indicated in efficacy between VectoLex WSP and VBC 60035 WSP. The test was conducted under highly challenging conditions, such as prehatch treatment, highly polluted water, and frequent flushing. Spore counting in water and sludge samples verified the presence of B. sphaericus spores on day 196 posttreatment, after 28 flushes. The results strongly indicate that WSP formulation of B. sphaericus could be one of the best candidates for controlling larvae of Culex mosquitoes developing in catch basins, with significant initial and residual efficacy.

    Fifty outbred Syrian golden hamsters were equally divided into three experimental groups and two control groups. The pouches of the experimental groups were painted bilaterally with a 0.5% 7,12-dimethylbenz[a]anthracene (DMBA) solution thrice a week for 3, 7 and 14 weeks. One of the control groups was applied with mineral oil while another control group remained untreated throughout the experiment. Neither survivin nor cIAP2 could be detected in any of the control tissues, whereas survivin and cIAP2 were found to be significantly increased in 3-, 7- and 14-week DMBA-treated pouches compared with the control pouches. Expression of XIAP, cIAP1 and NAIP were noted for both the control and 3-, 7- and 14-week DMBA-treated pouches, but levels were found to be significantly elevated in the experimental groups compared with the control pouches. p53 was not detected in any control tissues, but was significantly increased in 3-, 7- and 14-week DMBA-treated pouches. Direct sequencing revealed a point mutation (C-->G) of p53 for pouch tissues treated with DMBA for 3 and 7 weeks, and there was a wide variation in the p53 sequence of the 14-week DMBA-treated pouch tissues, as compared with the control tissues. The control tissues had a survivin- and cIAP2-methylated allele, whereas the DMBA-treated tissues showed no evidence of survivin- and cIAP2-methylation. Neither the control nor DMBA-treated pouches showed evidence of XIAP-, cIAP1- or NAIP-methylation. Our results suggest that the expression of inhibitors of apoptosis family in DMBA-induced hamster buccal-pouch squamous-cell carcinogenesis may be modulated by both genetic (mutant p53) and epigenetic mechanisms.

    Alcohol consumption among Swedish adolescents has halved during the last decade. We aim to: (i) investigate whether the overall decrease in drinking may conceal an underlying heterogeneity in drinking trajectories across at-risk groups that differ with respect to risk for drinking and; (ii) assess to what degree alcohol-related harm has responded to this decrease. Data were obtained from the nationally representative annual school survey of alcohol and drug habits among Swedish ninth-grade students covering the period 2000-2012 (n ≈ 5000/year). Respondents were divided into five at-risk groups ranging from low to high based on their relative ranking on a risk scale for drinking. Alcohol consumption was measured by beverage-specific quantity and frequency items summarised into a measure of overall drinking in litres of 100% alcohol per year. Alcohol-related harm was measured by eight items asking about whether the respondent had experienced various alcohol-related negative consequences. Drinking and alcohol-related harm decreased in all five at-risk groups. There was a marked relation between the overall consumption and the mean consumption in each of the five at-risk groups. Self-reported alcohol-related harm decreased during the study period to an extent that was expected from the decrease in alcohol consumption. Alcohol consumption among Swedish youth has declined in five groups that were delineated based on their relative ranking on a risk factor index. The findings are consistent with Skog's theory of the collectivity of drinking behaviour. [Norström T, Raninen J.

    The survival of selected lactic acid bacteria (LAB) with in vitro probiotic potential was studied during storage of cv. Halkidiki green olives previously subjected to inoculated Spanish-style fermentation. After fermentation olives were packed in polyethylene pouches, covered with freshly prepared brine (9%, w/v, NaCl), acidified with 2‰ (w/v) citric acid and 1.5‰ (w/v) ascorbic acid, and stored at 4 and 20 °C for 357 days. Four packing treatments were studied, namely olives previously fermented by (i) the indigenous microbiota (control); (ii) Lactobacillus pentosus B281; (iii) Lactobacillus plantarum B282; and (iv) a co-culture of both LAB strains. Microbiological analyses were performed on the olives in parallel with physicochemical changes (pH, titratable acidity, salt content, aw and colour) at the early (day 1), middle (day 197) and final stage (day 357) of storage, as well as sensory evaluation at the end of the storage. The survival of probiotic strains was confirmed by Pulsed Field Gel Electrophoresis (PFGE). LAB decreased throughout storage reaching a final population of ca. 3.5-4.0 log CFU/g and 4.5-5.0 log CFU/g at 4 and 20 °C, respectively. The pH values ranged between 3.90 and 4.61 during storage depending on packaging condition. PFGE analysis revealed that L. pentosus B281 and L. plantarum B282 showed a high survival rate with a recovery of 100 and 96%, respectively, at 4 °C, and less than 20% for both strains at 20 °C. Finally, in the packing treatment with a co-culture of both strains, L. pentosus dominated over L. plantarum throughout storage at both temperatures. Copyright © 2015 Elsevier Ltd.

    Full Text Available There is a long tradition in the production of spirit drinks and using them in the human diet, especially in the Southeast European and Mediterranean regions. The objective of this study was to evaluate whether and which spirits can serve, and to what extent, as a source of biologically active compounds in the human diet. Polyphenolic compounds are biologically active compounds of fruits, vegetables and derived beverages, which have been implicated in their antioxidant activity. Therefore, the total polyphenol content (TPC and antioxidative properties of 46 spirit drinks and liqueurs produced in Croatia were examined. The total polyphenol content and antioxidant activity were estimated using spectrophotometric methods (Folin-Ciocalteu, DPPH and FRAP, while certain phenols were detected by the HPLC. It was established that spirit drinks aged in wooden casks, such as wine or plum brandy, contain polyphenols ranging from 40-90 mg GAE/L (gallic acid equivalents, whereas walnut or sour cherry liquors contain much more polyphenols ranging from 680-3360 mg GAE/L. The antioxidant activity of analyzed spirit drinks was in correlation with TPC. Walnut and sour cherry liqueur samples had very high antioxidant activity, within the range of those obtained with 1.26 mM Trolox-DPPH assay and 9.5 mM Trolox-FRAP assay.

    Use of laser-etched pouches was investigated to develop kimchi packages with gas control functions. According to the degree of laser processing, the headspace pressure, atmospheric composition, and water vapor transmission rate of the kimchi packages were measured to investigate the potential use of laser-etched packages for kimchi. In addition, the pH, titratable acidity, organic acid, and microbial population of the packaged kimchi were examined to study the effect of packaging and storage conditions on its quality characteristics. The concentration of carbon dioxide in the pouches with a high gas transmission rate was less than that in other pouches (P kimchi (for example, pH, titratable acidity, organic acid, and microbial count). In addition, this study indicated that the higher the storage temperature, the more rapid the fermentation. Consequently, laser-etched pouches demonstrate the potential for controlling the gas, which in turn maintains the quality of kimchi. The use of laser-etched films could exert marked effects on alleviating the volume expansion or pressure build-up in kimchi packages. © 2017 Institute of Food Technologists®.

    As a breakthrough to open up the industrial use of novel environmentally benign packaging material, we propose the first report on portable chitosan-ZnO nano-composite pouches that will serve as elite entrants in smart packaging. A facile, one pot procedure was adopted for the preparation of the C-ZnC films. In order to tune the property of C-ZnC films, four different composite films were prepared by varying the concentration of ZnO. The prepared films were found to be much superior when compared to bare chitosan and other conventional films. Two bacterial strains that commonly contaminate in packed meat were selected as target microbes to elucidate the antimicrobial activity of the prepared C-ZnO film. Detailed investigations revealed that the antimicrobial efficiency is linearly related to the amount of ZnO nano-particles in the composite. The C-2 films exhibited excellent antimicrobial activity and was fabricated into packaging pouches for raw meat. The prepared pouches showed significant action against the microbes in raw meat owing to its complete inhibition of microbial growth on the sixth day of storage at 4°C. The C-2 pouches stand as a top-notch material when compared to polyethylene bag in extending the shelf life of raw meat. Copyright © 2017 Elsevier B.V. All rights reserved.

    The motility of the upper gut after Roux-en-Y gastric bypass (RYGBP) is underexplored. We aimed to investigate the oesophago-gastro-Roux limb motor activity during fasting and after food intake. Eighteen morbidly obese patients were examined at least 2 years after RYGBP. A high-resolution manometry catheter was positioned to straddle the oesophagogastric junction, the gastric pouch and the proximal Roux limb using transmucosal potential difference measurements. Three patients with vertical banded gastroplasty (VBG) were also studied. During the fasting state, the gastric pouch had low or no activity whereas the Roux limb exhibited regular migrating motility complexes (MMCs) being initiated just distal to gastroenteroanastomosis. Median cycle duration was 72 min, and the median propagating velocity of the phase III MMC phase was 2.7 cm/min (n = 8). When patients were asked to eat until they felt comfortably full, intraluminal pressure increased by 6 to 8 cmH₂O without any significant difference between gastric pouch and the Roux limb (n = 9). The increased intraluminal pressure following food intake correlated neither to weight loss nor to meal size or rate of eating. A successful RYGBP is associated with MMC in the Roux limb during fasting. The gastric pouch and the Roux limb behaved as a common cavity during food ingestion. Data do not support the hypothesis that the alimentary limb pressure in response to food intake influences either meal size or weight loss.

    The prevalence of Helicobacter pylori in obese candidates for bariatric surgery and its role in the emergence of inflammatory lesions after surgery has not been well established. To identify the incidence of inflammatory lesions in the stomach after bariatric surgery and to correlate it with H. pylori infection. This is a prospective study with 216 patients undergoing Roux-en-Y gastric bypass. These patients underwent histopathological endoscopy to detect H. pylori prior to surgery. Positive cases were treated with antibiotics and a proton inhibitor pump followed by endoscopic follow-up in the 6th and 12th month after surgery. Most patients were female (68.1%), with grade III obesity (92.4%). Preoperative endoscopy revealed gastritis in 96.8%, with H. pylori infection in 40.7% (88/216). A biopsy was carried out in 151 patients, revealing H. pylori in 60/151, related to signs of inflammation in 90% (54/60). In the 6th and 12th month after surgery, the endoscopy and the histopathological exam showed a normal gastric pouch in 84% of patients and the incidence of H. pylori was 11% and 16%, respectively. The presence of inflammation was related to H. pylori infection (ppresent in the new gastric reservoir it is directly related to H. pylori infection.

    This study was carried out to investigate the effect of irradiation on the expression of proliferating cell nuclear antigen (PCNA) and apoptosis induction during the carcinogenesis in hamster buccal pouch. Three months old Syrian golden hamsters were divided into control and 2 experimental groups. Hamsters in control group were left untreated on buccal pouchs. Twenty four hamsters were treated with 0.5% DMBA tri-weekly on the right buccal pouch. Forty eight hamsters were treated with 0.5% DMBA tri-weekly and irradiated with the dose of 5 Gy and 10 Gy at 6, 9, 12, 15 weeks after DMBA application. Resected buccal pouches were sectioned and examined for potential expression pattern of PCNA and apoptosis. The PCNA index was increased with the stages of buccal pouch epithelium carcinogenesis except the hyperplasia stage in control group (p<0.05). The irradiation did not effect on the PCNA index in the dysplasia and the carcinoma in situ stage, but in the hyperplasia stage, the PCNA index was increased with 10 Gy radiation and decreased in the carcinoma stage (p<0.05). The apoptotic index was significantly decreased from the carcinoma in situ stage and the lowest in the carcinoma stage. The apoptotic index was significantly decreased in the hyperplasia and dysplasia stage with the 5 Gy irradiation and significantly increased only in the carcinoma stage with the 10 Gy irradiation (p<0.05). The PCNA and apoptotic index were varied according to the irradiation period and dosage in each carcinogenesis stage.

    2001-07-01

    This study analyzes the process of constructing and reconstructing the meanings of the concepts ostomy, ostomy patient, and the nurse's role in managing an ostomy after the experience of wearing a pouch. Thirty nurses who were students in the Enterostomal Therapy Nursing Education Program in 1992 and 1993 participated in this study. All of the participants were female, ages 20 to 55 years, had graduated from nursing at least 6 years previously, and had been working at acute care hospital units or at outpatient care centers. The research was completed at the Enterostomal Therapy Nursing Education Program in the Nursing College of the University of São Paulo. All participants wore a pouch and lived as an ostomy patient for a 24-hour period and then were interviewed about their experience. Two major themes were identified after analysis: "being a person with an ostomy" and "being a professional." The experience of wearing a pouch promoted changes in perceived role, self-esteem, body image, sexuality, and social relations. These changes were sometimes perceived as stigmatization and sometimes as enhancing social support. The perceptions caused a crisis that provoked the use of coping and social defense mechanisms that ultimately altered the participants' perceptions of the meaning of "being a nurse." Prior to this learning experience, the participants' management of patients with ostomies was fragmented and marked by a dissociation among activity, thinking, and feeling. Before the experiences, participants defined their management of patients with ostomies as mostly technical, focusing on the ostomy and the pouch. Following the experience, participants proposed changes in practice designed to care for the whole human being, revealing an incorporation of the affective, symbolic, and relational dimensions critical to managing the care of patients with an ostomy. The results showed that having subjects wear a pouch as a pedagogic strategy was successful in directing the

    Full Text Available Background: The regular ingestion of fluoride lowers the prevalence of dental caries. The total daily intake of fluoride for optimal dental health should be 0.05-0.07 mg fluoride/kg body weight and to avoid the risk of dental fluorosis, the daily intake should not exceed a daily level of 0.10 mg fluoride/kg body weight. The main source of fluoride is from drinking water and other beverages. As in other countries, consumption of bottled water, juices and carbonated beverages has increased in our country. Objective: To analyze the fluoride content in bottled water, juices and carbonated soft drinks that were commonly available in Davangere city. Materials and Methods: Three samples of 10 commercially available brands of bottled drinking water, 12 fruit juices and 12 carbonated soft drinks were purchased. Bottled water and carbonated soft drinks were stored at a cold place until fluoride analysis was performed and a clear juice was prepared using different fruits without the addition of water. Then, the fluoride analysis was performed. Results: The mean and standard deviation of fluoride content of bottled water, fruit juices and carbonated soft drinks were measured, which were found to be 0.20 mg (±0.19 F/L, 0.29 mg (±0.06 F/L and 0.22 mg (±0.05 F/L, respectively. Conclusion: In viewing the results of the present study, it can be concluded that regulation of the optimal range of fluoride in bottled drinking water, carbonated soft drinks and fruit juices should be drawn for the Indian scenario.

    A new experimental model was developed in hamsters for amoebic abscess caused by Entamoeba histolytica. E. histolytica trophozoites were cultured in a liquid axenic medium, and then injected intradermally into the cheek pouch of the Syrian golden hamster, Mesocricetus auratus. Inoculation consistently resulted in abscess formation at the site in 20 of 22 (91%) study animals. The amoebic nature of the abscesses was confirmed by light microscopy and histopathologic examination. Abscess formation was maximal at day 12 post-inoculation. Potential applications of this simple and reliable model include further elucidation of the pathogenesis of invasive amoebiasis, studies of the host response to amoebae, and in vivo evaluation of chemotherapeutic agents that show in vitro efficacy against E. histolytica.

    Photodynamic therapy (PDT) is used to treat early proximal bronchial cancer during a flexible bronchoscopy. The technique relies on the excitation of a photosensitizer by an appropriate wavelength, which is delivered into the bronchus in close contact with the tumor. To assess methylene blue (MB) as a PDT agent for the treatment of respiratory tract cancer in animal models. MB-induced PDT was performed on 7 subcutaneous NCI-H460 lung adenocarcinoma xenografts in nude mice and 9 induced squamous cell cancer in the hamster cheek pouch model. In mice, PDT was carried out on right-sided tumors after intratumoral injection of methylene blue 1% (w/v) and illumination at 630nm at 200J/cm (Diomed PDT 630), with the left tumor used as control (illumination alone or MB alone). The tumoral volume was assessed before and 15 days after PDT. Fourteen xenografts were treated in mice, including seven treated with MB-PDT, producing a 52% mean tumor volume regression (1568mm(3)vs. 544mm(3)) compared to seven control cases in which tumor volume increased (p=0.007; Mann-Whitney test). Nine cheek pouch induced carcinomas were treated in the hamster group, with a mean volume decrease of 85.8% (from 44.8% to 100%) (initial mean volume=210mm(3)vs. post PDT mean volume=97mm(3)). Histology analysis showed 4/9 complete responses. Intratumoral MB appears efficient as PDT agent for cancer treatment in animal models. Further studies are needed to assess the safety and efficacy of MB-associated PDT for the treatment of lung cancer in humans. Copyright © 2016 The Authors. Published by Elsevier B.V.

    Full Text Available The objective of this study was to evaluate the osteoinductivity of composite chitosan-nano-hydroxyapatite scaffolds in a rat muscle pouch model. Previous in vitro characterization demonstrated the ability of the scaffolds to promote bone regeneration and as a carrier for local delivery of BMP-2. Composite microspheres were prepared using a co-precipitation method, and scaffolds were fabricated using an acid wash to adhere beads together. To determine the in vivo osteoinductivity of the scaffolds, the following groups (n = 6 were implanted into muscle pouches created in the latissimus dorsi of Sprague Dawley rats: (A lyophilized scaffolds without rhBMP-2, (B lyophilized scaffolds with rhBMP-2, (C non-lyophilized scaffolds with rhBMP-2, and (D absorbable collagen sponge with rhBMP-2 (control. Groups B, C, and D were loaded with 4 mL of a 9.0 μg/mL solution of rhBMP-2 for 48 h. The rats were sacrificed after one month and samples were analyzed for amount of residual implant material, new bone, and osteoid. Although the experimental groups displayed minimal degradation after one month, all of the scaffolds contained small amounts of woven bone and considerable amounts of osteoid. Approximately thirty percent of the open space available for tissue ingrowth in the scaffolds contained new bone or osteoid in the process of mineralization. The ability of the composite scaffolds (with and without BMP-2 to promote ectopic bone growth in vivo was demonstrated.

    In an attempt to understand better the status of renal function after Kock pouch urinary diversion we conducted a prospective evaluation of renal function in 25 patients using the radionuclide 131iodine-hippurate. Studies were done before, and at 1 month and every 6 months for 30 months postoperatively. The radionuclide results were then compared to excretory urography and contrast study of the reservoir. Our renal function study included the determination of individual and total effective renal plasma flow (ml. per minute), the time to maximal radioactivity over the kidney (peak time in minutes) and a renogram. The mean total (both kidneys) effective renal plasma flow rates before (25 patients) and at month 1 (19), month 6 (14), month 12 (12), month 18 (6), month 24 (6) and month 30 (7) after operation were 385.5 +/- 112.2, 310.5 +/- 109.9, 362.7 +/- 69.2, 442.0 +/- 97.5, 468.2 +/- 82.5, 405.7 +/- 70.6 and 414.0 +/- 65.1, respectively. A comparison of individual and total effective renal plasma flow before and after operation revealed that only the change of the flow at each or both sides of the kidney before and at 1 month after the operation reached statistically significant differences, respectively (p less than 0.05, paired t test). Postoperatively 5 of 6 patients with hydronephrosis had abnormal peak time and a third segment on the renogram was performed on the corresponding side of the kidney. No reflux was noted on contrast study of the reservoir of any patient followed for up to 30 months. In conclusion, the radionuclide renal function evaluation showed a significant decrease of renal function 1 month after Kock pouch diversion, then it resumed and remained stable (neither improved nor deteriorated) for 30 months. Also the abnormal peak time and third segment on the renogram usually implicated a dilated upper urinary tract.

    Despite evidence that many people engage in solitary drinking and that it might be associated with negative consequences, to date, little research has focused on this form of drinking behaviour. This study examined the prevalence and factors associated with solitary drinking, and assessed whether it is linked with hazardous alcohol use among males in nine countries of the former Soviet Union (fSU). Data came from a cross-sectional population-based survey undertaken in 2010/11 in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, and Ukraine. Information was obtained on the frequency of solitary drinking among male regular drinkers (i.e., those consuming alcoholic drinks at least once a month), and on problem drinking (CAGE) and heavy episodic drinking (HED). Logistic regression analysis was used to examine associations between the variables. The prevalence of occasional and frequent solitary drinking ranged from 8.4% (Georgia) to 42.4% (Azerbaijan), and 3.1% (Kazakhstan) to 8.2% (Armenia), respectively. Solitary drinking was associated with being older, divorced/widowed, living alone, having a bad/very bad household financial situation, lower levels of social support, and poor self-rated health. Occasional solitary drinking was linked to problem drinking and HED, while frequent solitary alcohol use was related to problem drinking. Solitary drinking is relatively common among male regular drinkers in the fSU and is linked to older age, social and economic disadvantage, and hazardous alcohol use.

    Research characterizing the adolescent drinking context is limited, often relies on samples of current drinkers reporting on recent/last or typical drinking experiences, and provides little information about the context of very early use. The present study uses repeated monthly assessments to describe the context of drinking days and matched non-drinking days to determine the unique risk associated with different drinking-related characteristics. Additionally, we used latent class analysis to empirically identify key configurations of drinking-related characteristics and both family- and non-family-related environmental characteristics (social context, physical location, source of alcohol). Data included 688 days (344 drinking days, 344 non-drinking days) from 164 middle-school students enrolled in a prospective study on drinking initiation and progression (62% female; 26% non-White, 11% Hispanic). Results supported four patterns: (1) heavier drinking occurring in a peer context, lighter drinking occurring in (2) a family context or (3) a peer context, and (4) drinking alcohol obtained at home without permission. Latent classes varied as a function of gender, age, peer norms, and parenting behaviors as well as alcohol type and perceived alcohol availability. Findings indicated that highly endorsed contexts were not necessarily the riskiest ones, and simply targeting an oft-reported source of alcohol, physical location, or social context may not be an effective strategy for reducing underage drinking. Additionally, although greater monitoring and anticipated parent reaction to drinking are typically protective against adolescent drinking, we found they were associated with parent-sanctioned drinking, suggesting the role of parenting practices must be considered in the context of drinking pattern.

    To describe benefits and adverse effects associated with the consumption of energy drinks. Searches were conducted using Medline, IPA (International Pharmaceutical Abstracts), EMBASE, and MANTIS; databases such as Natural Medicines Comprehensive Database, Natural Standard, ALTMEDEX, and AltHealthWatch; and Google (range 1980 to September 2007). Search terms included energy drink, Red Bull, caffeine, glucose, ginseng, guarana, taurine, and bitter orange. Most energy drinks contain natural products such as guarana, ginseng, and taurine. As much as 80 to 300 mg of caffeine and 35 grams of processed sugar per 8-ounce serving are commonly present in energy drinks such as Cocaine, Pimp Juice, Red Bull, and Spike Shooter. No reports were identified of negative effects associated with taurine, ginseng, and guarana used in the amounts found in most energy drinks. Commonly reported adverse effects seen with caffeine in the quantities present in most energy drinks are insomnia, nervousness, headache, and tachycardia. Four documented case reports of caffeine-associated deaths were found, as well as four separate cases of seizures associated with the consumption of energy drinks. The amounts of guarana, taurine, and ginseng found in popular energy drinks are far below the amounts expected to deliver either therapeutic benefits or adverse events. However, caffeine and sugar are present in amounts known to cause a variety of adverse health effects.

  1. Development and Characterization of a Carbonated Ginger Drink

    Full Text Available There is widespread of effort in developing countries like Nigeria to develop carbonated drink from the locally source materials. To achieve this aim, ginger has been consider as an alternative material for the production of carbonated drink, this is because ginger and its by-products have a lot of applications in confectionaries, pharmaceuticals and beverages production. Apart from the applications of ginger listed above, ginger is also a very important and highly valuable crop in most part of West African, Japan, and China. In this study, ginger soft drink was developed by a combination of fresh ginger rhizome and Carbon dioxide (CO2. The CO2 gas volume was steadily increased to make three (3 samples B, C, and D, while sample A is the non-carbonated sample. All the samples were characterized according to chemical and microbiological analysis of the final product and values obtained from the analysis of the developed ginger soft drink are within the range of standard values for carbonated drink. Shelf-life analysis was carried out on the final product and it corresponds to the Shelf-life of a standard carbonated drink. Sample D with the highest gas volume of 2.8 cm3 has the best Shelf-life. Results obtained from the various analysis conducted indicates that the production of a carbonated ginger soft drink from fresh ginger rhizome is practically possible, cost effective and has numerous advantages when compared with other available carbonated drinks.

    There is considerable excitement about implicit alcohol associations (IAAs) as predictors of college-student hazardous drinking; however, few studies have investigated IAAs prospectively, included multiple assessments, or controlled for previous drinking. Doing so is essential for showing the utility of these associations as predictors, and ultimately, targets for screening or intervention. Therefore, 3 IAAs (i.e., drinking identity, alcohol approach, and alcohol excitement) were evaluated as prospective predictors of drinking in 1st- and 2nd-year undergraduates in the United States. A sample of 506 undergraduates completed 8 online assessments of IAAs, explicit measures of the IAA constructs, and hazardous drinking (i.e., consumption, problems, and risk of alcohol-use disorders) every 3 months over a 21-month period. Retention rates, ordered by follow-up time points, were 90%, 76%, 76%, 77%, 72%, 67%, and 66%, respectively. Half of the participants were nondrinkers at baseline; 21% were above clinical cutoffs for hazardous drinking. Drinking-identity and alcohol-excitement associations predicted future alcohol consumption and problems after controlling for previous drinking and explicit measures; drinking identity also predicted future risk of alcohol-use disorder. Relative to the other IAAs, drinking identity predicted alcohol consumption for the longest duration (i.e., 21 months). Alcohol-approach associations rarely predicted variance in drinking. IAAs vary in their utility as prospective predictors of college-student hazardous drinking. Drinking identity and, to a lesser extent, alcohol excitement, emerged as robust prospective predictors of hazardous drinking. Intervention and screening efforts could likely benefit from targeting those associations. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    In a study applying a utility analysis to drinking behavior, a questionnaire on beliefs about the effects of alcohol and the desirability of those effects was administered to a sample of college students and a sample drawn from the population. Measures of the expected utility of drinking were calculated. Utility scores were positively related to drinking habits, due to heavier drinkers' increased expectations of positive consequences of drinking and more positive evaluation of all consequences. It is suggested that studies on expectancies about drinking should include not only measures of behavioral expectations but measures of the desirability of alcohol effects.

    Energy drinks are widely consumed by adolescents as these claim to improve performance, endurance and alertness. Recent reports have shown that there are no real health benefits of these drinks. On the contrary, certain adverse effects due to energy drinks have come to the forefront, casting a big question-mark on their safety and utility. This review discusses the present status of energy drinks, their active ingredients and their safety. We conclude that energy drinks, despite having some short pleasant effects, can be harmful for the body and are best avoided.

  6. CERN’s Drinking Water

    CERN Multimedia

    GS Department

    CERN’s drinking water is monitored on a regular basis. A certified independent laboratory takes and analyses samples to verify that the water complies with national and European regulations for safe drinking water. Nevertheless, the system that supplies our drinking water is very old and occasionally, especially after work has been carried out on the system, the water may become cloudy or discoloured, due to traces of corrosion. For this reason, we recommend: Never use hot water from the tap for drinking or cooking. If you need hot water, then draw water from the cold water tap and heat it. Only drink or cook with cold water. Let the cold water run until it is clear before drinking or making your tea or coffee. If you have any questions about the quality of CERN’s drinking water, please contact: Jerome Espuche (GS/SEM), Serge Deleval (EN/CV) or Jonathan Gulley (DG/SCG).

    Peer pressure is consistently implicated in the excessive drinking of college students. However, both theory and empirical findings suggest that peer pressure is a combination of three distinct influences: overt offers of alcohol, modeling, and social norms. Overt offers of alcohol can range from polite gestures to intense goading or commands to drink. Modeling occurs when the student's behavior corresponds to another student's concurrent drinking behavior. Perceived social norms can serve to make excessive alcohol use appear common and acceptable to the student. This review critically examines the literature on each form of peer influence and provides suggestions for future research.

    Although alcohol is socially accepted in most Western societies, studies are clear about its associated negative consequences, especially among university and college students. Studies on the relationship between alcohol-related consequences and both beverage type and drinking onset, however, are scarce, especially in a European context. The aim of this research was, therefore, twofold: (1) What is the relationship between beverage type and the negative consequences experienced by students? and (2) Are these consequences determined by early drinking onset? We will examine these questions within the context of a wide range of alcohol-related consequences. The analyses are based on data collected by the inter-university project 'Head in the clouds?', measuring alcohol use among students in Flanders (Belgium). In total, a large dataset consisting of information from 19,253 anonymously participating students was available. Negative consequences were measured using a shortened version of the Core Alcohol and Drug Survey (CADS_D). Data were analysed using negative binomial regression. Results vary depending on the type of alcohol-related consequences: Personal negative consequences occur frequently among daily beer drinkers. However, a high rate of social negative consequences was recorded for both daily beer drinkers and daily spirits drinkers. Finally, early drinking onset was significantly associated with both personal and social negative consequences, and this association was especially strong between beer and spirits drinking onset and social negative consequences. Numerous negative consequences, both personal and social, are related to frequent beer and spirits drinking. Our findings indicate a close association between drinking beer and personal negative consequences as well as between drinking beer and/or spirits and social negative consequences. Similarly, early drinking onset has a major influence on the rates of both personal and social negative consequences

  9. Soft drinks and 'desire to drink' in preschoolers

    2008-12-01

    Full Text Available Abstract Interest in soft drink consumption has increased following a dramatic rise in intake over recent years. Research to date has focused primarily on general trends in consumption or on understanding the mechanism by which soft drink consumption may be linked to weight gain. It is clear however that there is considerable individual variability in the extent to which soft drinks are consumed and factors potentially influencing intake have received little attention. This study examines how the Child Eating Behaviour Questionnaire (CEBQ construct 'Desire to Drink' (DD relates to drink consumption, preferences and BMI-SDS. Three hundred and forty six same-sex twin children (mean age 11.2 years; s.d. 0.54; 56% female; 53% dizygotic were weighed, measured and reported their liking for milk, water, fruit juice, fruit squash and sweetened soft drinks. Mothers reported on their child's drink consumption and completed the CEBQ. Scores on the CEBQ DD subscale were not significantly related to child BMI-SDS in this sample. Children scoring higher on DD had higher preferences for sugar-sweetened soft drinks (p = 0.016, fruit squash (p = 0.042 and milk (p = 0.020 than children scoring lower on the scale. DD was also positively related to more frequent consumption of sugar-sweetened soft drinks (p = 0.017 and low calorie soft drinks (p = 0.003. No relationship was observed between DD scores and liking for or intake of water or 100% fruit juice. These findings suggest that the construct desire to drink in children is related to a liking for consuming sweetened drinks, and does not appear to simply denote greater thirst or hunger. This may have important implications for the ongoing development of dietary patterns and weight status in the longer term through an increased preference for sweet things in the mouth and a failure to compensate for calories provided by drinks.

    Drinking water quality is the great public health concern because it is a major risk factor for high incidence of diarrheal diseases in Nepal. In the recent years, the prevalence rate of diarrhoea has been found the highest in Myagdi district. This study was carried out to assess the quality of drinking water from different natural sources, reservoirs and collection taps at Arthunge VDC of Myagdi district. A cross-sectional study was carried out using random sampling method in Arthunge VDC of Myagdi district from January to June,2010. 84 water samples representing natural sources, reservoirs and collection taps from the study area were collected. The physico-chemical and microbiological analysis was performed following standards technique set by APHA 1998 and statistical analysis was carried out using SPSS 11.5. The result was also compared with national and WHO guidelines. Out of 84 water samples (from natural source, reservoirs and tap water) analyzed, drinking water quality parameters (except arsenic and total coliform) of all water samples was found to be within the WHO standards and national standards.15.48% of water samples showed pH (13) higher than the WHO permissible guideline values. Similarly, 85.71% of water samples showed higher Arsenic value (72) than WHO value. Further, the statistical analysis showed no significant difference (Pwater for collection taps water samples of winter (January, 2010) and summer (June, 2010). The microbiological examination of water samples revealed the presence of total coliform in 86.90% of water samples. The results obtained from physico-chemical analysis of water samples were within national standard and WHO standards except arsenic. The study also found the coliform contamination to be the key problem with drinking water.

    Although problematic alcohol use has been studied extensively in undergraduate students, little is known about problematic drinking among postgraduate students. This study examined binge drinking, prepartying, and mixing alcohol with energy drinks to determine: (1) the extent to which postgraduate students engage in these drinking behaviors, (2) how postgraduate students differ from undergraduate students in these behaviors, and (3) the demographic risk factors for these behaviors in postgraduate (and undergraduate) students. This study utilized data from n = 695 students (n = 298 postgraduate; n = 397 undergraduate) who participated in the Healthy Minds Study at a large, public university in the Midwestern US. Past-two-week binge drinking, past-year and past-30-day prepartying, and past-30-day mixing alcohol with energy drinks were reported by 26.2%, 28.6%, 14.9%, and 8.1% of postgraduate students, respectively. Multivariate analyses indicated that postgraduate status was a significant negative predictor of binge drinking and prepartying, and that status interacted with age in predicting prepartying such that the effect of age on prepartying was negative for postgraduate students and nonsignificant for undergraduates. Age was a significant negative predictor of mixing alcohol with energy drinks for all students. This study makes a unique contribution to the literature by providing information on problematic drinking in postgraduate students. Although there was evidence of "maturing out," a substantial number of postgraduate students were found to engage in binge drinking and prepartying, and a not insubstantial number of them were found to mix alcohol with energy drinks.

    Several very popular brands of isotonic and energy drinks consumed for fluid and electrolyte supplementation and stimulation of mental or physical alertness were chosen for investigation. Liquid beverages available in polyethylene bottles and aluminum cans as well as products in the form of tablets and powder in sachets were studied. The total concentrations of 21 elements (Ag, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Na, Ni, P, Pb, Sr, Ti, V, and Zn), both essential and toxic, were simultaneously determined in preconcentrated drink samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) equipped with pneumatic and ultrasonic nebulizers. Differences between the mineral compositions of isotonic and energy drinks were evaluated and discussed. The highest content of Na was found in both isotonic and energy drinks, whereas quite high concentrations of Mg were found in isotonic drinks, and the highest amount of calcium was quantified in energy drinks. The concentrations of B, Co, Cu, Ni, and P were higher in isotonic drinks, but energy drinks contained greater quantities of Ag, Cr, Zn, Mn, and Mo and toxic elements, as Cd and Pb. A comparison of element contents with micronutrient intake and tolerable levels was performed to evaluate contribution of the investigated beverages to the daily diet. The consumption of 250 cm(3) of an isotonic drink provides from 0.32% (for Mn) up to 14.8% (for Na) of the recommended daily intake. For the energy drinks, the maximum recommended daily intake fulfillment ranged from 0.02% (for V) to 19.4 or 19.8% (for Mg and Na).

    Full Text Available Congenital pouch colon (CPC is frequently associated with vesicoureteric reflux (VUR. These patients require long-term antibiotic prophylaxis and/or an additional surgical intervention for the management of the refluxing system. We propose a single-stage alternative approach in these patients. Two patients diagnosed to have CPC underwent pouch excision and an end colostomy at birth. Further evaluation revealed high-grade reflux in both the patients. At 6 months of age, definitive abdominoperineal pull-through (APPT surgery along with extravesical detrusorrhaphy was performed. In the follow-up at 1 year, they are thriving well with no urinary complaints. Micturating cystourethrogram revealed complete resolution of VUR. This approach takes the advantage of the anesthesia for APPT and offers a relatively simple and quick solution for the refluxing system, thus, enabling the stoppage of antibiotic prophylaxis and obviating the need for a future endoscopy/surgery.

    Recent research has identified the use of caffeinated energy drinks as a common, potentially risky behavior among college students that is linked to alcohol misuse and consequences. Research also suggests that energy drink consumption is related to other risky behaviors such as tobacco use, marijuana use and risky sexual activity. This research sought to examine the associations between frequency of energy drink consumption and problematic alcohol use, alcohol-related consequences, symptoms of alcohol dependence and drinking motives in an ethnically diverse sample of college students in Alaska. We also sought to examine whether ethnic group moderated these associations in the present sample of White, Alaska Native/American Indian and other ethnic minority college students. A paper-and-pencil self-report questionnaire was completed by a sample of 298 college students. Analysis of covariance (ANCOVA) was used to examine the effects of energy drink use, ethnic group and energy drink by ethnic group interactions on alcohol outcomes after controlling for variance attributed to gender, age and frequency of binge drinking.

There were no main effects of ethnic group, and there were no significant energy drink by ethnic group interactions. These findings replicate those of other studies examining the associations between energy drink use and alcohol problems, but contrary to previous research we did not find ethnic minority status to be protective.

    Full Text Available Background. Recent research has identified the use of caffeinated energy drinks as a common, potentially risky behaviour among college students that is linked to alcohol misuse and consequences. Research also suggests that energy drink consumption is related to other risky behaviours such as tobacco use, marijuana use and risky sexual activity. Objective. This research sought to examine the associations between frequency of energy drink consumption and problematic alcohol use, alcohol-related consequences, symptoms of alcohol dependence and drinking motives in an ethnically diverse sample of college students in Alaska. We also sought to examine whether ethnic group moderated these associations in the present sample of White, Alaska Native/American Indian and other ethnic minority college students. Design. A paper-and-pencil self-report questionnaire was completed by a sample of 298 college students. Analysis of covariance (ANCOVA was used to examine the effects of energy drink use, ethnic group and energy drink by ethnic group interactions on alcohol outcomes after controlling for variance attributed to gender, age and frequency of binge drinking. Results. Greater energy drink consumption was significantly associated with greater hazardous drinking, alcohol consequences, alcohol dependence symptoms, drinking for enhancement motives and drinking to cope. There were no main effects of ethnic group, and there were no significant energy drink by ethnic group interactions. Conclusion. These findings replicate those of other studies examining the associations between energy drink use and alcohol problems, but contrary to previous research we did not find ethnic minority status to be protective. It is possible that energy drink consumption may serve as a marker for other health risk behaviours among students of various ethnic groups.

    Sports drinks are becoming increasingly popular as we are all being encouraged to adopt a healthier lifestyle with regular exercise. However, many of these products are based on acidic fruits and may contribute to erosion. The aim of this study was to screen a number of these products for their potential to cause enamel erosion in vitro. The erosive potential of a number of readily available sports drinks was assessed in the laboratory by measuring their pH, neutralisable acidity and their ability to erode enamel. These were compared to a positive control, orange juice and a negative control, water. The pH of the sports drinks ranged from 3.16-3.70 with their neutralisable acidity ranging from 9.74-13.44 mls of 0.1M NaOH. The amount of enamel removed following 1-hour immersion in the sports drinks ranged from 1.18-5.36 microns. In comparison, the orange juice control had a pH of 3.68, a neutralisable acidity of 19.68 mls of 0.1 M NaOH and removed 3.24 microns of enamel. Many of the sports drinks tested were found to be erosive. This information will be of use to clinicians when counselling patients with tooth surface loss who use fruit based sports drinks regularly.

    Prior studies adjusting self-reported measures of alcohol intake for drink size and ethanol (EtOH) content have relied on single-point assessments. A prospective 28-day diary study investigated magnitudes of drink-EtOH adjustments and factors associated with these adjustments. Transdermal alcohol sensor (TAS) readings and prediction of alcohol-related problems by number of drinks versus EtOH-adjusted intake were used to validate drink-EtOH adjustments. Self-completed event diaries listed up to 4 beverage types and 4 drinking events/d. Eligible volunteers had ≥ weekly drinking and ≥3+ drinks per occasion with ≥26 reported days and pre- and postsummary measures (n = 220). Event reports included drink types, sizes, brands or spirits contents, venues, drinks consumed, and drinking duration. Wine drinks averaged 1.19, beer 1.09, and spirits 1.54 U.S. standard drinks (14 g EtOH). Mean-adjusted alcohol intake was 22% larger using drink size and strength (brand/EtOH concentration) data. Adjusted drink levels were larger than "raw" drinks in all quantity ranges. Individual-level drink-EtOH adjustment ratios (EtOH adjusted/unadjusted amounts) averaged across all days drinking ranged from 0.73 to 3.33 (mean 1.22). Adjustment ratio was only marginally (and not significantly) positively related to usual quantity, frequency, and heavy drinking (all ps alcohol dependence symptoms (p Alcoholism.

    A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

  1. Using daily reports to measure drinking and drinking patterns.

    Science.gov (United States)

    Leigh, B C

    2000-01-01

    Daily measurements of drinking are used to measure alcohol consumption, validate retrospective questionnaires, and examine associations between drinking and other behaviors. The advantages of using daily reports include reducing retrospective biases and forgetting of drinking occasions; disadvantages include increased costs and potential for reactivity. Methodological issues to consider in using daily reports include reporting method (written, telephone, electronic), reporting interval, data collection period, respondent attrition, and missing data. Compared to retrospective reports, daily reports result in more reported drinking occasions but similar average quantity consumed, and correlations between retrospective and daily measures are generally high. The utility of daily reports depends on the research question and the purpose of the measurements.

    The Ruscus extract and the flavonoid hesperidine methylchalcone (HMC) are used in treatment of venous insufficiency. In the present study, we used the hamster cheek pouch preparation and investigated the effects of these substances on increased microvascular permeability induced by bradykinin, histamine, and leukotriene B4 (LTB4) applied topically. Experiments were performed on male hamsters; 30 min after completion of the cheek pouch preparation, fluorescein-labeled dextran [molecular weight (mol wt) 150,000] was given intravenously (i.v.). Bradykinin, histamine, and LTB4 increased the number of fluorescent vascular leakage sites from postcapillary venules, evidence for an increase in macromolecular permeability, which was quantified in ultraviolet (UV)-light microscope as the number of leaky sites in the prepared area. Ruscus extract and HMC, given i.v., significantly inhibited the macromolecular permeability-increasing effect of bradykinin, LTB4, and histamine. Ruscus extract, applied topically, dose dependently inhibited the macromolecular permeability-increasing effect of histamine. Our results show that Ruscus extract and HMC have a protective effect against leakage of FITC-dextran in the cheek pouch after administration of various permeability-increasing substances, which further supports data previously reported on patients with venous insufficiency.

      CERN’s drinking water is monitored, with regular samples being taken and analysed by a certified independent laboratory, which checks on compliance with national and European regulations for safe drinking water. Nevertheless, the drinking water network is very old and occasionally, especially after work has been carried out on the network, the clarity and colour of the water can be adversely affected due to high levels of corrosion in suspension. Some basic recommendations should always be followed: Never use hot water from the tap for drinking or cooking. If you need hot water, then draw water from the cold water tap before heating it. Only drink or cook with cold water. Let the cold water run until you notice that the water has become clear.

    To determine the frequency and pattern of energy drink consumption among medical school students, their knowledge of its effects and side effects and to see its relation with alcohol and cigarette usage. The descriptive analytical study was conducted at Marmara University Medical School, Istanbul, Turkey from October 2011 and January 2012. A semi-structured questionnaire was filled by students who were asked about their socio-demographic status and their energy drink consumption. SPSS 12 was used for statistical analysis. The mean age of the 390 students in the study was 20.98+/-1.96 years (range:16-27). Of them, 204 (52.3%) were females and 186 (47.7%) were males. Overall 52(13.3%) were smoking regularly at least one cigarette per day; 122(31.3%) were consuming alcohol; 127 (32.6%) had consumed energy drinks at least once and 73(18.8%)more than once. In terms of perception, 110(28.2%) students said energy drinks were similar to sports drinks, while only 121(41.1%) named the brands correctly; 96 (24.6%) students did not answer this particular question. Although consumption of energy drinks was common among medical students, the knowledge of ingredients and knowledge of health risks of energy drinks among them was unsatisfactory.

    Sports drinks were originally developed to improve hydration and performance in athletes taking part in intense or endurance sporting events. These drinks contain relatively high amounts of carbohydrates (sugars), salt, and citric acid. These ingredients create the potential for dental ramifications and overall public health consequences such as obesity and diabetes. High intake of sports drinks during exercise, coupled with xerostomia from dehydration, may lead to the possibility of erosive damage to teeth.

In 30 respondents with sufficiently high quality TAS readings, higher correlations (p=.04) were found between the adjusted vs. the raw drinks/event and TAS areas under the curve. Conclusions Absent drink size and strength data, intake assessments are downward biased by at least 20%. Between-subject variation in typical drink content and pour sizes should be addressed in treatment and epidemiological research. PMID:25581661

    2015-12-16

    Octopuses of the genus Cistopus Gray, 1849 are commercially valuable catches in the cephalopod fisheries of India. The primary and unique diagnostic character of this genus is the possession of eight small mucous pouches embedded in the oral faces of the webs between the bases of each arm. Historically only a single species of Cistopus, C. indicus, had been reported from Indian waters. In reviewing the octopod fauna off the Kerala coast, we have detected three species of Cistopus, of which one is described here as a new species. Cistopus platinoidus sp. nov. is distinct from Cistopus species described to date (C. indicus, C. taiwanicus and C. chinensis) on the basis of sucker counts, the number and position of enlarged suckers in males, and presence/absence of a calamus. Our studies of catch composition of Kerala octopod fisheries indicate a higher diversity of target species than previously suspected, including a number of undescribed species. Taxonomic resolution and collation of biological and distributional data are required for effective monitoring and management of these valuable fisheries.

    The role of non-skin phototoxic dose of Photofrin in the detection of dysplasia and carcinoma in situ was assessed in a small animal model of oral squamous cell cancer (SCC). Nine,10-dimethyl 1,2-benzanthracene (DMBA) impregnated cotton sutures, covered with a silicone sheath, were sewn into the hamster cheek pouch to produce dysplasia, carcinoma in situ, and invasive cancer. The yield of SCC was 83% by 20 weeks. Fluorescence imaging was performed using a specially designed device that exploits differences of fluorescence properties of normal, precancerous, and cancerous tissues with and without Photofrin. The fluorescence was induced by a helium-cadmium laser (442 nm) and then measured at two different wavelengths by an image intensified camera. Computed images using a mathematical transformation of fluorescence data were then displayed on a video monitor. Areas with dysplasia and both in situ and invasive cancers could be clearly delineated from the adjacent normal tissues. Lesions as small as 2 mm in diameter could be identified. Because of the presence of endogenous porphyrins, the addition of a non-skin phototoxic dose of Photofrin (0.25 mg/kg iv) did not enhance the signal to noise ratio. Our results suggest that fluorescence imaging can accurately detect both precancerous and cancerous lesions in the oral mucosa without exogenous porphyrins. It may have an important role as a non-invasive, clinical diagnostic tool in oropharyngeal cancer.

    Graphite/lithium nickel-manganese-cobalt oxide (NMC), stacked pouch cells with nominal capacity of 15-18 Ah were designed, developed, and manufactured for automotive applications in the frame of the European Project GREENLION. A natural, water-soluble material was used as the main electrode binder, thus allowing the employment of H2 O as the only processing solvent. The electrode formulations were developed, optimized, and upscaled for cell manufacturing. Prolonged cycling and ageing tests revealed excellent capacity retention and robustness toward degradation phenomena. For instance, above 99 % of the initial capacity is retained upon 500 full charge/discharge cycles, corresponding to a fading of 0.004 % per cycle, and about 80 % of the initial capacity is delivered after 8 months ageing at 45 °C. The stacked soft-packaged cells have shown very reproducible characteristics and performance, reflecting the goodness of design and manufacturing. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Phosphate dosing of drinking water supplies, coupled with leakage from distribution networks, represents a significant input of phosphorus to the environment. The oxygen isotope composition of phosphate (δ(18)OPO4), a novel stable isotope tracer for phosphorus, offers new opportunities to understand the importance of phosphorus derived from sources such as drinking water. We report the first assessment of δ(18)OPO4 within drinking water supplies. A total of 40 samples from phosphate-dosed distribution networks were analyzed from across England and Wales. In addition, samples of the source orthophosphoric acid used for dosing were also analyzed. Two distinct isotopic signatures for drinking water were identified (average = +13.2 or +19.7‰), primarily determined by δ(18)OPO4 of the source acid (average = +12.4 or +19.7‰). Dependent upon the source acid used, drinking water δ(18)OPO4 appears isotopically distinct from a number of other phosphorus sources. Isotopic offsets from the source acid ranging from -0.9 to +2.8‰ were observed. There was little evidence that equilibrium isotope fractionation dominated within the networks, with offsets from temperature-dependent equilibrium ranging from -4.8 to +4.2‰. While partial equilibrium fractionation may have occurred, kinetic effects associated with microbial uptake of phosphorus or abiotic sorption and dissolution reactions may also contribute to δ(18)OPO4 within drinking water supplies.

    A range of negative health outcomes are associated with young adults' drinking practices. One key arena where images of, and interaction about, drinking practices occurs is social networking sites, particularly Facebook. This study investigated the ways in which young adults' talked about and understood their uses of Facebook within their drinking practices. Face-to-face, semi-structured interviews were conducted with seven New Zealand young adults as they displayed, navigated and talked about their Facebook pages and drinking behaviours. Our social constructionist thematic analysis identified three major themes, namely 'friendship group belonging', 'balanced self-display' and 'absences in positive photos'. Drinking photos reinforced friendship group relationships but time and effort was required to limit drunken photo displays to maintain an overall attractive online identity. Positive photos prompted discussion of negative drinking events which were not explicitly represented. Together these understandings of drinking photos function to delimit socially appropriate online drinking displays, effectively 'airbrushing' these visual depictions of young adults' drinking as always pleasurable and without negative consequences. We consider the implications of these findings for ways alcohol health initiatives may intervene to reframe 'airbrushed' drinking representations on Facebook and provoke a deeper awareness among young people of drinking practices and their online displays.

    Uranium concentration in drinking water samples collected from some areas of Northern Rajasthan has been measured using inductively coupled plasma mass spectrometry. The water samples were taken from hand pumps. The uranium concentration in water samples varies from 2.54-133.0 μg L with a mean value of 38.48 μg L. The uranium concentration in most of the drinking water samples exceeds the safe limit (30 μg L) recommended by the World Health Organization. The annual effective dose associated with drinking water due to uranium concentration is estimated from its annual intake using dosimetric information based on ICRP 72. The resulting value of the annual effective dose from drinking water sources is in the range of 2.11-110.45 μSv. The annual effective dose in one of the samples was found to be greater than WHO-recommended level of 100 μSv y.

    We have developed an animal model of alcohol self-administration that initially employs schedule-induced polydipsia (SIP) to establish reliable ethanol consumption under open access (22 h/d) conditions with food and water concurrently available. SIP is an adjunctive behavior that is generated by constraining access to an important commodity (e.g., flavored food). The induction schedule and ethanol polydipsia generated under these conditions affords the opportunity to investigate the development of drinking typologies that lead to chronic, excessive alcohol consumption. Adult male cynomolgus monkeys (Macaca fascicularis) were induced to drink water and 4% (w/v in water) ethanol by a Fixed-Time 300 seconds (FT-300 seconds) schedule of banana-flavored pellet delivery. The FT-300 seconds schedule was in effect for 120 consecutive sessions, with daily induction doses increasing from 0.0 to 0.5 g/kg to 1.0 g/kg to 1.5 g/kg every 30 days. Following induction, the monkeys were allowed concurrent access to 4% (w/v) ethanol and water for 22 h/day for 12 months. Drinking typographies during the induction of drinking 1.5 g/kg ethanol emerged that were highly predictive of the daily ethanol intake over the next 12 months. Specifically, the frequency in which monkeys ingested 1.5 g/kg ethanol without a 5-minute lapse in drinking (defined as a bout of drinking) during induction strongly predicted (correlation 0.91) subsequent ethanol intake over the next 12 months of open access to ethanol. Blood ethanol during induction were highly correlated with intake and with drinking typography and ranged from 100 to 160 mg% when the monkeys drank their 1.5 g/kg dose in a single bout. Forty percent of the population became heavy drinkers (mean daily intakes >3.0 g/kg for 12 months) characterized by frequent "spree" drinking (intakes >4.0 g/kg/d). This model of ethanol self-administration identifies early alcohol drinking typographies (gulping the equivalent of 6 drinks) that evolve into

    To examine whether the frequency and amount of alcohol consumed in binge drinking sessions, total annual volume of alcohol consumed, problem drinking and abstaining from alcohol are associated with depressive symptoms in Eastern Europe. Cross-sectional data from a total of 24,381 participants from general population samples of the Czech Republic (N = 7,601), Russia (N = 6,908) and Poland (N = 9,872) aged 45-69 years in 2002-2005. Depressive symptoms were defined as ≥ 16 points on the Centre for Epidemiological Studies - Depression (CES-D) scale. Several alcohol related measures were derived using responses from the graduated frequency questionnaire. Binge drinking was defined at several sex-specific thresholds (ranging from 60+ to 140+ g of ethanol) and two frequencies (at least monthly or weekly). Total annual alcohol intake in grams was also extracted. Problem drinking was defined as ≥ 2 positive answers on the CAGE questionnaire. Problem drinking was consistently associated with approximately a 2-fold increase in odds of depressive symptoms across all countries and in both sexes. Abstaining from alcohol was typically associated with increased odds of depressive symptoms. Analyses separating lifelong abstainers and former drinkers in the Russian cohort revealed that this increased odds was driven by former drinkers. Amongst men, heavy frequent binge drinking was associated with increased odds of depressive symptoms in the Czech Republic and Poland. In women, heavy infrequent binge drinking was associated with increased odds of depressive symptoms in Russia and Poland. Only in Polish men was higher annual volume of alcohol intake associated with increased odds of depressive symptoms. Abstaining from alcohol and problem drinking were associated with increased odds of depressive symptoms in these Eastern European populations. Annual volume of alcohol intake as well as frequency and amount of alcohol consumed in a binge drinking session were less consistently

    A 14-year-old boy came to my office to discuss his frequent consumption of energy drinks to enhance his performance at school and while playing soccer. What is the recommended use of energy drinks in children and is there any harm in consuming them? Energy drinks are beverages with a high concentration of caffeine and additional stimulants. They are sold in numerous places and are easily accessed by children, adolescents, and young adults. Many reports warn about potential adverse effects associated with their consumption, especially in combination with alcohol among adolescents, and in combination with stimulant medications among children treated for attention deficit hyperactivity disorder. Children and adolescents should avoid energy drinks, and health care providers should educate youth and their parents about the risks of caffeinated drinks.

    There is some evidence that college student drinkers may continue drinking in the face of adverse consequences. We examined 2 hypotheses: (a) that this seemingly pathological behavior is a phenomenon of university life, occurring with consistency throughout the entirety of college, and (b) that individuals accumulate these consequences over multiple semesters in college. A sample of 3,720 students from a large Midwestern university was asked to complete surveys the summer before college and every semester thereafter for 4 years. Results showed that certain drinking-related consequences (e.g., blackouts, regretted sexual experiences) consistently predicted continued frequent heavy drinking in the following semester, even after controlling for sex, race, age, and previous-semester frequent heavy drinking (range of odds ratio = 1.17 to 1.45 across semesters, p students. For example, 13.8% of students reported blacking out 5 time-points or more—describing a full half or more of their college careers. Experimental studies which aim to modify students’ perceptions of norms associated with these consequences may aid in developing interventions to reduce the burden of harm to students. In the broader context, and given the prevalence of students’ accumulation of consequences, future study might aim to determine how and in what ways these findings describe either pathological or normative processes.

    Metal-on-metal hip replacement implants generate wear debris and release ions both locally and systemically in patients. To investigate dissemination of metal, we determined blood and organ levels of cobalt (Co), chromium (Cr), and molybdenum (Mo) following the implantation of Co-Cr alloy wear debris in mice using skin pouches as a model system. We observed increased metal levels in blood for up to 72 h; the levels of Co were highest and remained elevated for 7 days. Co levels were elevated in all organs studied (liver, kidney, spleen, lung, heart, brain, and testes), with the peak at 48 h; highest levels were measured in liver and kidney (838.9 ± 223.7 ng/g in liver, and 938.8 ± 131.6 ng/g in kidney). Organ Cr levels were considerably lower than Co levels, for example, Cr in kidney was 117.2 ± 12.6 ng/g tissue at 48 h. Co is more mobile than Cr, reaching higher levels at earlier time points. This could be due to local tissue binding of Cr. Exposure to Co-Cr particles in vivo altered antioxidant enzyme expression and activities. We observed induction of catalase protein in the liver and glutathione reductase (GR) and peroxidase (GPx) proteins in the spleen. Activities of catalase and GPx in the liver were significantly increased while that of GR was decreased in the kidney. Organs of mice with Co-Cr particle implantation were exposed to increased metal levels capable of inducing reactive oxygen species scavenging enzymes, suggesting the tissue may be subjected to oxidative stress; however, the overall antioxidant defence system was not markedly disturbed.

    Underage drinking and its associated problems have profound negative consequences for underage drinkers themselves, their families, their communities, and society as a whole, and contribute to a wide range of costly health and social problems. There is increased risk of negative consequences with heavy episodic or binge drinking. Alcohol is a factor related to approximately 4,300 deaths among underage youths in the U.S. every year. Since the mid-1980s, the nation has launched aggressive underage drinking prevention efforts at the federal, state, and local levels, and national epidemiologic data suggest that these efforts are having positive effects. For example, since 1982, alcohol-related traffic deaths among youth aged 16-20 years have declined by 79%. Evidence-based or promising strategies for reducing underage drinking include those that limit the physical, social, and economic availability of alcohol to youth, make it illegal for drivers aged drinking, and provide mechanisms for early identification of problem drinkers. Strategies may be implemented through a comprehensive prevention approach including policies and their enforcement, public awareness and education, action by community coalitions, and early brief alcohol intervention and referral programs. This paper focuses on underage drinking laws and their enforcement because these constitute perhaps the most fundamental component of efforts to limit youth access to and use of alcohol.

    Full Text Available Introduction: Current Thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. They cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. The main objective of this study is to introduce the designing and manufacturing the first Drinking Simulator Unit (DSU that reproduces the thermal, color and chemicalcycling as well as the drinking behavior and oral temperature in lab conditions uniquely. Methods: The invented system generally has two parts: the hardware and the software parts. The hardware consists of the mechanical and electronic parts. The software part is responsible for controlling the heating and cooling systems, electric valves, the pumps, and automatic filling systems of tanks as well as the sensors of the machine. Results: DSU is the first unit can reproduce the thermal, color and chemical cycling as well as the drinking behavior and oral temperature in lab conditions. Different kinds of colored and acidic drinks and also other chemical materials such as bleaching substances as well as detergents and antiseptics used for dentistry, industrial and medical purposes can be tested by DSU. DSU has also to be considered as an appliance performing in-vitro researches on dental structures. Conclusion: The invented system can greatly improve and validate the results of such researches.

    The term "energy drink" designates "any product in the form of a drink or concentrated liquid, which claims to contain a mixture of ingredients having the property to raise the level of energy and vivacity". The main brands, Red Bull, Dark Dog, Rockstar, Burn, and Monster, are present in food stores, sports venues, and bars among other soft drinks and fruit juices. Their introduction into the French market raised many reluctances, because of the presence of taurine, caffeine and glucuronolactone. These components present in high concentrations, could be responsible for adverse effects on health. The association of energy drinks and spirits is widely found among adolescents and adults who justify drinking these mixed drinks by their desire to drink more alcohol while delaying drunkenness. Given the importance of the number of incidents reported among the energy drinks consumers, it seemed appropriate to make a synthesis of available data and to establish causal links between the use of these products and the development of health complications. For a literature review, we selected scientific articles both in English and French published between 2001 and 2011 by consulting the databases Medline, Embase, PsycINFO and Google Scholar. The words used alone or in combination are "energy dinks", "caffeine", "taurine", "toxicity", "dependence". An occasional to a moderate consumption of these drinks seems to present little risk for healthy adults. However, excessive consumption associated with the use of alcohol or drugs in amounts that far exceed the manufacturers recommended amount, could be responsible for negative consequences on health, particularly among subjects with cardiovascular disease.

    Boron neutron capture therapy (BNCT) is based on selective accumulation of B-10 carriers in tumor followed by neutron irradiation. We demonstrated, in 2001, the therapeutic effect of BNCT mediated by BPA (boronophenylalanine) in the hamster cheek pouch model of oral cancer, at the RA-6 nuclear reactor. Between 2007 and 2011, the RA-6 was upgraded, leading to an improvement in the performance of the BNCT beam (B2 configuration). Our aim was to evaluate BPA-BNCT radiotoxicity and tumor control in the hamster cheek pouch model of oral cancer at the new "B2" configuration. We also evaluated, for the first time in the oral cancer model, the radioprotective effect of histamine against mucositis in precancerous tissue as the dose-limiting tissue. Cancerized pouches were exposed to: BPA-BNCT; BPA-BNCT + histamine; BO: Beam only; BO + histamine; CONTROL: cancerized, no-treatment. BNCT induced severe mucositis, with an incidence that was slightly higher than in "B1" experiments (86 vs 67%, respectively). BO induced low/moderate mucositis. Histamine slightly reduced the incidence of severe mucositis induced by BPA-BNCT (75 vs 86%) and prevented mucositis altogether in BO animals. Tumor overall response was significantly higher in BNCT (94-96%) than in control (16%) and BO groups (9-38%), and did not differ significantly from the "B1" results (91%). Histamine did not compromise BNCT therapeutic efficacy. BNCT radiotoxicity and therapeutic effect at the B1 and B2 configurations of RA-6 were consistent. Histamine slightly reduced mucositis in precancerous tissue even in this overly aggressive oral cancer model, without compromising tumor control.

    Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) is effective for treatment of human oral precancerous lesions. This animal study aimed to assess whether topical methotrexate (MTX) pretreatment could enhance the therapeutic effect of topical ALA-PDT on hamster buccal pouch precancerous lesions. Twenty hamster buccal pouch precancerous lesions were treated with either topical ALA-PDT with topical MTX pretreatment (topical MTX-ALA-PDT group, n = 10) or topical ALA-PDT alone (topical ALA-PDT group, n = 10). The intracellular protoporphyrin IX (PpIX) level in another 12 precancerous lesions (n = 6 for either the topical MTX-ALA or topical ALA group) was monitored by fluorescence spectroscopy. The intracellular PpIX reached its peak level in precancerous lesions 6.5 hours and 2.5 hours after topical ALA application for the topical MTX-ALA group (5.63-fold higher in the lesion than in the normal mucosa) and topical ALA group (2.42-fold higher in the lesion than in the normal mucosa), respectively. The complete response rate of precancerous lesions was 80% for the topical MTX-ALA-PDT group and 70% for the topical ALA-PDT group. In addition, the topical MTX-ALA-PDT group required a significantly lower mean treatment number (2.1 ± 0.6) to achieve complete response than the topical ALA-PDT group (4.4 ± 1.3, p hamster buccal pouch precancerous lesions and significantly improves the outcomes of the precancerous lesions treated with topical ALA-PDT.

    The chemopreventive efficacy of turmeric has been established in experimental systems. However, its mechanism(s) of action are not fully elucidated in vivo. The present study investigates the mechanism of turmeric-mediated chemoprevention in 7,12-dimethylbenz(a)anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis at 2, 4, 6, 10 and 12 weeks. Dietary turmeric (1%) led to decrease in DMBA-induced tumor burden and multiplicity, and enhanced the latency period in parallel, to its modulatory effects on oncogene products and various cellular responses during HBP tumorigenesis. DMBA-induced expression of ras oncogene product, p21 and downstream target, the mitogen-activated protein kinases were significantly decreased by turmeric during HBP carcinogenesis. Turmeric also diminished the DMBA-induced mRNA expression of proto-oncogenes (c-jun, c-fos) and NF-kappaB, leading to decreased protein levels and in further attenuation of DMBA-induced AP-1/NF-kappaB DNA-binding in the buccal pouch nuclear extracts. Besides, buccal pouch of hamsters receiving turmeric diet showed significant alterations in DMBA-induced effects: (a) decrease in cell proliferation (diminished PCNA and Bcl2 expression), (b) enhanced apoptosis (increased expression of Bax, caspase-3 and apoptotic index), (c) decrease in inflammation (levels of Cox-2, the downstream target of AP-1/NF-kappaB, and PGE2) and (d) aberrant expression of differentiation markers, the cytokeratins (1, 5, 8, and 18). Together, the protective effects of dietary turmeric converge on augmenting apoptosis of the initiated cells and decreasing cell proliferation in DMBA-treated animals, which in turn, is reflected in decreased tumor burden, multiplicity and enhanced latency period. Some of these biomarkers are likely to be helpful in monitoring clinical trials and evaluating drug effect measurements.

    Full Text Available Research has found that “internal” or personal attributions about the causes of problem drinking increase the likelihood of seeking treatment and treatment efficacy, while “external” attributions, such as environmental, social or cultural causations, may hinder treatment efforts. Results of survey data from a sample of 152 US college students found three main causation belief factors, which were differentially associated with age, heavy drinking, protestant religion, and exposure to problem drinkers. The "Social Cause" factor was the most strongly endorsed belief suggesting external, but surmountable attributions for problem drinking. Implications of attributions for treatment efficacy are discussed.

This study attempted to examine that motive by including health as one of six motives for drinking, along with measures of problem drinking (the Cut-down, Annoyed, Guilty, Eye-opener [CAGE] questionnaire in an older adult population.Design: Four drinking motives (enhancement, coping, social, and conformity, plus taste and health were included within a larger national telephone survey on drinking behaviors. We also recorded beverage preference.Results: In this analysis, 705 participants drank a preferred beverage. Taste was the most highly endorsed motive. Just under one quarter of the sample endorsed health as a positive reason for drinking. After controlling for age, sex, and preferred alcoholic beverage, the internal psychological motives of enhancement and coping predicted CAGE scores, but external motives did not. Believing that alcohol is healthy was a negative predictor of CAGE scores. Our results showed a different pattern to those with younger drinkers reported in previous research. Our older group was less likely to drink for social reasons and internal motives were predictive of CAGE scores.Conclusion: A motives-based approach to managing problem drinking will need to take account of a wider range of age-related motives. Based on the current data, there is little reason to suspect drinking wine for health reasons is associated with potential problem drinking.Keywords: drinking behavior, wine and drinking motives, healthy drinking, wine and health

    Public Service Announcements tailored to specific college drinking rituals (Treise, Wolburg and Otnes 1999) were tested on 133 underage undergraduate drinkers. More significant reductions in drinking intentions were found when using appeals focusing on drinking rituals pertaining to Maturity/Order (older students drink moderately: "Don't drink like a freshman.") than to Transformation (desired personality and mood changes), Community (social bonding and camaraderie), or a no-message Control. Gender did not moderate this effect. Underage drinkers may drink, in part, to feel more "grown up." Emphasizing that more senior students actually drink responsibly may diminish this belief and result in reduced alcohol consumption among underage students.

    To enhance prevention efforts to reduce college drinking, parents have been identified as an important source of influence that can be modified with brief interventions. Research suggests parental permissiveness toward drinking in adolescence is positively related to college student drinking, though existing studies have not comprehensively accounted for potential confounders (e.g., parental drinking). The present study used propensity modeling to estimate the effects of pre-college parental permissiveness on college student drinking and consequences while accounting for an inclusive range of confounders. A random sample of 1,518 incoming students at a large university completed baseline measures of parental permissiveness and a list of confounders (e.g., parental drinking, family history). At follow-up 15 months later, participants reported on their drinking and alcohol-related consequences. To control for potential confounders, individuals were weighted based on their propensity scores to obtain less biased estimates of the effects of parental permissiveness on drinking and consequences. Analyses revealed parental permissiveness was consistently and positively associated with college drinking and consequences when the confounders were not accounted for, but these effects were attenuated after weighting. Parents' allowance of drinking was not related to college drinking or consequences after weighting. Students' perceived parental limits for consumption were related to drinking and consequences in the weighted models. Prevention efforts may benefit from targeting parents' communication of acceptable limits for alcohol consumption.

    Underage drinking contributes to the 3 leading causes of death (unintentional injury, homicide, and suicide) among persons aged 12 to 20 years. Most adverse health effects from underage drinking stem from acute intoxication resulting from binge drinking. Although binge drinking, typically defined as consuming > or = 5 drinks on an occasion, is a common pattern of alcohol consumption among youth, few population-based studies have focused specifically on the characteristics of underage binge drinkers and their associated health risk behaviors. We analyzed data on current drinking, binge drinking, and other health risk behaviors from the 2003 National Youth Risk Behavior Survey. Prevalence estimates and 95% confidence intervals were calculated by using SAS and SUDAAN statistical software. Logistic regression was used to examine the associations between different patterns of alcohol consumption and health risk behaviors. Overall, 44.9% of high school students reported drinking alcohol during the past 30 days (28.8% binge drank and 16.1% drank alcohol but did not binge drink). Although girls reported more current drinking with no binge drinking, binge-drinking rates were similar among boys and girls. Binge-drinking rates increased with age and school grade. Students who binge drank were more likely than both nondrinkers and current drinkers who did not binge to report poor school performance and involvement in other health risk behaviors such as riding with a driver who had been drinking, being currently sexually active, smoking cigarettes or cigars, being a victim of dating violence, attempting suicide, and using illicit drugs. A strong dose-response relationship was found between the frequency of binge drinking and the prevalence of other health risk behaviors. Binge drinking is the most common pattern of alcohol consumption among high school youth who drink alcohol and is strongly associated with a wide range of other health risk behaviors.

    To analyze the outcomes of j-pouch and side-to-end anastomosis in rectal cancer patients treated with laparoscopic hand-assisted low anterior resection. Prospective trial on cases randomized to have a colonic j-pouch or a side-to-end anastomosis after low anterior resection. Demographics, characteristics of disease and treatment, perioperative results, and functional outcomes and life quality were compared between the groups. Seventy four patients were randomized. Reservoir creation was withdrawn in 17 (23%) patients, mostly related to reach problem (n = 11, 64.7%). Anastomotic leakage rate was significantly higher in j-pouch group (8 [27.6%] vs. 0, p = 0.004). Stoma closure could not be achieved in 16 (28.1%) patients. Life quality and functional outcomes, measured 4, 8 and 12 months after the stoma reversal, were similar. Colonic j-pouch and side-to-end anastomosis are similar regarding perioperative measures including operation time, rates of postoperative complications, reoperation and 30-day mortality, and hospitalization period except anastomotic leak rate, which is higher in j-pouch group. Postoperative aspects are not different in patients receiving either technique including functional outcomes and life quality for the first year after stoma closure. In our opinion, both techniques may be preferred during the daily practice while performing laparoscopic surgery; but surgeons may be aware of a possibly higher anastomotic leak rate in case of a j-pouch.

    The functional properties of 4 binders, namely corn starch, wheat semolina, wheat flour, and tapioca starches, were evaluated to improve the quality of buffalo meat nuggets processed in retort pouches at F(0) 12.13. Incorporation of corn starch in buffalo meat nuggets produced more stable emulsion than other binders used. Product yield, drip loss, and pH did not vary significantly between the products with different binders. Shear force value was significantly higher for product with corn starch (0.42 +/- 0.0 Kg/cm(3)) followed by refined wheat flour (0.36 +/- 0.010 Kg/cm(3)), tapioca starch (0.32 +/- 0.010 Kg/cm(3)), and wheat semolina (0.32 +/- 0.010 Kg/cm(3)). Type of binder used had no significant effect on frying loss, moisture, and protein content of the product. However, fat content was higher in products with corn starch when compared to products with other binders. Texture profile indicated that products made with corn starch (22.17 +/- 2.55 N) and refined wheat flour (21.50 +/- 0.75 N) contributed firmer texture to the product. Corn starch contributed greater chewiness (83.8 +/- 12.51) to the products resulting in higher sensory scores for texture and overall acceptability. Products containing corn starch showed higher sensory scores for all attributes in comparison to products with other binders. Panelists preferred products containing different binders in the order of corn starch (7.23 +/- 0.09) > refined wheat flour (6.48 +/- 0.13) > tapioca starch (6.45 +/- 0.14) > wheat semolina (6.35 +/- 0.13) based on sensory scores. Histological studies indicated that products with corn starch showed dense protein matrix, uniform fat globules, and less number of vacuoles when compared to products made with other binders. The results indicated that corn flour is the better cereal binder for developing buffalo meat nuggets when compared to all other binders based on physico-chemical and sensory attributes.

    Few studies have examined the relationship of social anxiety with drinking game participation. Drinking games represent a popular form of drinking in university settings. Due to their structure, games may appeal to socially anxious drinkers, particularly among those seeking to fit in or cope with the social setting. To examine the relationship of social anxiety with frequency of drinking game participation among a university undergraduate sample and to investigate if drinking motives moderate this association. A total of 227 undergraduate students aged 18-24 years (73% female) who had consumed alcohol in the prior year were included in the current investigation. Hierarchical regression examined the influences of social anxiety and drinking motives on frequency of drinking game participation, as well the interactions of social anxiety with drinking for coping motives and conformity motives. Social anxiety failed to emerge as a significant predictor of frequency of drinking game participation. However, drinking to cope moderated the relationship of social anxiety with frequency of drinking game participation. Socially anxious students who drank to cope were more likely to participate in drinking games on occasions when they consumed alcohol than those who did not endorse this drinking motive. Results demonstrated the influence of drinking to cope in the relationship of social anxiety with frequency of drinking game participation. Future work should examine the relationship with other indicators of drinking game activity. Intervention efforts addressing social anxiety and drinking should consider motives for drinking, as well as drinking patterns.

    Transforming growth factor-β (TGF-β) and its receptors are considered as a novel target in cancer chemotherapy. Gramine, an indole alkaloid, possesses various pharmacological properties including antiproliferative and anticancer. However, the anti-angiogenic property remains unexplored. The present study was designed to evaluate the anti-angiogenic and apoptosis induction properties of gramine through inhibiting TGF-β on DMBA induced oral squamous cell carcinoma (OSCC) in the hamster buccal pouch (HBP). The effects of gramine on TGF-β signalling in DMBA induced carcinogenic events such as angiogenesis and apoptosis were analysed by studying the mRNA expression using RT-PCR, protein expression by western blot and histopathological analysis using haematoxylin and eosin (H & E) staining. Gramine significantly inhibited phosphorylation and nuclear translocation of Smad2 and Smad4 by blocking activity of the TGFβ-RII, RI and activation of inhibitory Smad7. Gramine inhibited angiogenic markers such as MMP-2, MMP-9, HIF-1α, VEGF, and VEGF-R2 as well as increased TIMP-2 expression. Furthermore, gramine induced apoptosis in DMBA induced tumour bearing animals by up regulating the pro apoptotic proteins Bax, cytochrome C, apaf-1, caspase-9 caspase-3 and PARP. In this study, we clearly demonstrated that gramine treatment diminishes angiogenesis and induces apoptosis in hamster buccal pouch (HBP) carcinogenesis by modulating TGF-β signals.

    In the present study, post-treatment effects of dietary turmeric on markers related to apoptosis, cell proliferation, and inflammation in 7,12-dimethylbenz(a)anthracene (DMBA)-induced hamster buccal pouch (HBP) tumors were investigated. Tumors were induced by applying 0.5% DMBA topically to the HBP three times per week for 12 weeks. After tumor development, half of the animals continued on the control diet and the other half were shifted to a 1% turmeric diet for 4 weeks. To rule out DMBA discontinuation as a cause of inhibition in tumor growth, DMBA treatment was continued during dietary exposure of turmeric in another set of animals until the end of the experiment. The turmeric diet inhibited tumor growth in animals with or without DMBA carcinogen treatment compared to the animals on the control diet. When compared to hamsters bearing tumors that remained on the control diet, the buccal pouches of hamsters bearing tumors receiving turmeric showed the following results: (1) decreased cell proliferation (diminished PCNA, cyclin D1, and Bcl-2) and PCNA labelling index, (2) enhanced apoptosis (increased Bax, caspase-3, caspase-9, and cytochrome c, and decreased survivin) and apoptotic index, (3) decreased inflammation (decreased Cox-2), and (4) decreased MAPK activation (p-ERK and p-p38). These data indicate that tumor growth decreased due to the modulation of cellular pathways associated with cell proliferation and apoptosis.

    The babassu palm tree is native to Brazil and is most densely distributed in the Cocais region of the state of Maranhão, in northeastern Brazil. In addition to the industrial use of refined babassu oil, the milk, the unrefined oil and the nuts in natura are used by families from several communities of African descendants as one of the principal sources of food energy. The objective of this study was to evaluate the effects of babassu oil on microvascular permeability and leukocyte-endothelial interactions induced by ischemia/reperfusion using the hamster cheek pouch microcirculation as experimental model. Twice a day for 14 days, male hamsters received unrefined babassu oil (0.02 ml/dose [BO-2 group], 0.06 ml/dose [BO-6 group], 0.18 ml/dose [BO-18 group]) or mineral oil (0.18 ml/dose [MO group]). Observations were made in the cheek pouch and macromolecular permeability increase induced by ischemia/reperfusion (I/R) or topical application of histamine, as well as leukocyte-endothelial interaction after I/R were evaluated. The mean value of I/R-induced microvascular leakage, determined during reperfusion, was significantly lower in the BO-6 and BO-18 groups than in the MO one (P nut and its oil might be secure sources of food energy.

    Pre-gaming, the practice of consuming alcohol before attending a social function, has not received as much research attention as drinking games among college students. This study investigated the prevalence of both pre-gaming and drinking game participation in a sample of mandated students (N = 334) who had been referred for an alcohol violation. Approximately one-third (31%) of the sample reported pre-gaming on the night of their referral event. Pre-gaming was associated with higher estimated blood alcohol content on that night, along with a greater history of pre-gaming and taking greater responsibility for the incident. A higher proportion of the students (48.7%) reported playing drinking games on the event night and reported the event to be less aversive than non-players. Neither drinking games nor pre-gaming was consistently related to recent alcohol consumption or problems, nor did they frequently occur together on the event night. Pre-gaming was a unique predictor of intoxication on the night of the referral, and drinking games were not. Therefore, pre-gaming and drinking games appear to be distinct activities. This research suggests methods of prevention for both activities as well as promising research directions for future research. PMID:17574344

    Energy drink consumption in the United States has more than doubled over the last decade and has been implicated in cardiac arrhythmias, myocardial infarction, and even sudden cardiac death. We hypothesized that energy drink consumption may increase the risk of adverse cardiovascular events by increasing platelet aggregation, thereby resulting in a relatively hypercoagulable state and increased risk of thrombosis. Thirty-two healthy volunteers aged 18-40 y were given 16 oz of bottled water or a standardized, sugar-free energy drink on two separate occasions, 1-wk apart. Beverages were consumed after an overnight fast over a 30-min period. Coagulation parameters and platelet function were measured before and 60 min after consumption using thrombelastography and impedance aggregometry. No statistically significant differences in coagulation were detected using kaolin or rapid thrombelastography. In addition, no differences in platelet aggregation were detected using ristocetin, collagen, thrombin receptor-activating peptide, or adenosine diphosphate-induced multiple impedance aggregometry. However, compared to water controls, energy drink consumption resulted in a significant increase in platelet aggregation via arachidonic acid-induced activation (area under the aggregation curve, 72.4 U versus 66.3 U; P = 0.018). Energy drinks are associated with increased platelet activity via arachidonic acid-induced platelet aggregation within 1 h of consumption. Although larger clinical studies are needed to further address the safety and health concerns of these drinks, the increased platelet response may provide a mechanism by which energy drinks increase the risk of adverse cardiovascular events.

    2011-08-01

    Surrogate, nonbeverage alcohols, provide a cheap and concentrated source of ethanol for drinking that has been associated with premature mortality. The aim of this study was to provide the first estimate of the prevalence of surrogate alcohol consumption in a national population sample of Estonia. The Estonian Health Interview Survey conducted in 2006 to 2007 was a nationally representative sample of the population aged 15 to 84 years (N = 6,370). The age-standardized percentage prevalences of ever having drunk surrogates were estimated. The association of age, ethnicity, and education with the prevalence of surrogate drinking was estimated using logistic regression. Of all respondents who reported drinking at least once in their lifetime (N = 5,423), 65% had consumed alcohol during the previous 4 weeks. In this group (N = 3,525), the age-standardized prevalence rate of surrogate drinking was 1.4% (2.3% men, 0.3% women). Among men, surrogate drinking was rare under the age of 35 years (0.3%). Ethnicity and education were both related to surrogate drinking: relative to Estonian men, non-Estonians (mainly Russians) had an odds ratio (OR) for surrogate drinking (adjusted for age and education) of 2.58 (95% CI 1.41, 4.72), while relative to those with higher education those with secondary education had an OR (adjusted for age and ethnicity) of 2.28 (0.78, 6.67) and those with basic education an OR of 3.91 (1.29, 11.84). Surrogate alcohols are drunk in Estonia, particularly among men. This behavior shows pronounced variation in prevalence by ethnicity and education. Reducing consumption of these substances needs to be part of any strategy to reduce the burden of alcohol-related problems in Estonia today. Copyright © 2011 by the Research Society on Alcoholism.

    To examine key individual- and community-level correlates of regular very high-risk drinking (more than 20 drinks at least 12 times a year for males and more than 11 drinks at least 12 times a year for females) among young (16-24) drinkers in Victoria. CATI survey of 10,879 young Victorian drinkers. Multi-level modelling of correlates of proportion drinking at very high-risk levels at both individual (e.g. age, gender) and community levels (e.g. alcohol outlet density, remoteness). One-fifth of the sample reported regular (at least monthly) very high-risk drinking. Significant individual-level correlates of very high-risk drinking included age, gender, cultural background, recreational spending money, life stage, living situation, family conflict and age at first drink. Significant community-level correlates included remoteness (living in a rural area) and packaged liquor outlet density. The study highlights a range of important factors relating to regular drinking of dangerous amounts of alcohol by youth. Interventions aimed at preventing early initiation or managing recreational spending should be explored. Further, regulatory management of packaged liquor outlets and or remote rural communities in Victoria with high levels of dangerous drinking should be a priority.

    2010-04-01

    Energy drinks are frequently marketed to individuals interested in athletics and an active lifestyle. From 2001 to 2008, estimates of energy drink use in adolescent to middle-aged populations ranged from 24% to 56%. Most energy drinks feature caffeine and a combination of other components, including taurine, sucrose, guarana, ginseng, niacin, pyridoxine, and cyanocobalamin. This article examines the evidence for 2 commonly purported uses of energy drinks: athletic performance enhancement and weight loss. Observed ergogenic benefits of energy drinks are likely attributable to caffeine and glucose content. There is conflicting evidence regarding the impact of energy drinks on weight loss, although some data suggest that combining energy drink use with exercise may enhance body fat reduction. As with any pharmacologically active substance, energy drinks are associated with adverse effects. Combining energy drinks with alcohol exacerbates safety concerns and is an increasingly common practice contributing to toxic jock identity among college-aged male athletes. Practitioners should monitor identified populations likely to consume these loosely regulated beverages.

  13. Collegiate Heavy Drinking Prospectively Predicts Change in Sensation Seeking and Impulsivity

    2011-01-01

    Recent models of alcohol use in youth and young adulthood have incorporated personality change and maturation as causal factors underlying variability in developmental changes in heavy drinking. Whereas these models assume that personality affects alcohol use, the current prospective study tested the converse relation. That is, we tested whether, after accounting for the effect of traits on drinking, collegiate heavy drinking in turn predicted individual differences in change in alcohol-related aspects of personality. We also examined whether affiliation with heavy-drinking peers better accounted for this relation. Following a cohort of recent high school graduates (N = 1,434) through the college years, we found evidence for transactional relations between heavy drinking and changes in impulsivity and sensation seeking. Both traits predicted increases in heavy drinking, but more importantly, heavy drinking predicted increases in sensation seeking and impulsivity. In final models, social influences did not underlie the effect of heavy drinking on increases in sensation seeking and impulsivity. The results of this investigation suggest that collegiate heavy drinking may negatively and pervasively impact a wide range of behaviors because of its effect on personality change. PMID:21443288

    We examined the effectiveness of a drinking plan (goal setting), and a drinking diary (self monitoring), in the intervention program (HAPPY program), for heavy drinkers in the workplace. 115 people participated, and 80 people were evaluated three months later and 31 people were evaluated one year later. We classified the drinking plans in the limitation of the quantity, non-drinking days, and the device of low risk drinking model. 75 people made the drinking diary for 12 weeks after brief intervention and studied three months later and 31 people were analyzed one year later. We evaluated on heavy drinking days of 28 days, and non-drinking days of 28 days and standard drinks of 7 days. The limitation of the quantity model is effective for low risk drinking. The non-drinking day model is easily achieved, but not effective for low risk drinking. The device of low risk drinking model improved drinking habits for a long-term. The drinking diary for 12 weeks after intervention improved drinking habits for a long-term. The drinking plan (goal setting), and drinking diary (self monitoring), in intervention program for heavy drinkers were effective for prevention of lifestyle-related disease and alcoholism.

    2014-09-01

    Heavy drinking is common among students at UK universities. US students overestimate how much their peers drink and correcting this through the use of social norm messages may promote responsible drinking. We tested whether there is an association between perceived campus drinking norms and usual drinking behavior in UK university students and whether norm messages about responsible drinking correct normative misperceptions and increase students' intentions to drink responsibly. 1,020 UK university students took part in an online study. Participants were exposed to one of five message types: a descriptive norm, an injunctive norm, a descriptive and injunctive norm, or one of two control messages. Message credibility was assessed. Afterwards participants completed measures of intentions to drink responsibly and we measured usual drinking habits and perceptions of peer drinking. Perceptions of peer drinking were associated modestly with usual drinking behavior, whereby participants who believed other students drank responsibly also drank responsibly. Norm messages changed normative perceptions, but not in the target population of participants who underestimated responsible drinking in their peers at baseline. Norm messages did not increase intentions to drink responsibly and although based on accurate data, norm messages were not seen as credible. In this UK based study, although perceived social norms about peer drinking were associated with individual differences in drinking habits, campus wide norm messages about responsible drinking did not affect students' intentions to drink more responsibly. More research is required to determine if this approach can be applied to UK settings.

  16. The influence of parental and peer drinking behaviors on underage drinking and driving by young men.

    2012-01-01

    Studies have consistently found that parental and peer drinking behaviors significantly influence adolescent drinking behavior and that adolescent drinking has a significant effect on their drinking-and-driving behavior. Building upon these studies, the present article assesses whether parental and peer drinking behaviors have direct and indirect effects on adolescent drinking and driving as well as whether they moderate the effect of adolescent drinking on their drinking-and-driving behavior. The assessment is conducted using data collected from the Buffalo Longitudinal Survey of Young Men (BLSYM) with Ordinary Least Squares (OLS) regression analyses. The data reveal that peer drinking has direct and indirect effects on adolescent drinking-and-driving behavior when adolescent drinking behavior is controlled. It also moderates the effect of adolescent drinking behavior on their drinking and driving. However, parental drinking does not have these direct and interactive effects, although it may have an indirect effect on adolescent drinking and driving via adolescent drinking behavior. These findings imply that peer drinking behavior should be considered seriously in prevention and intervention for reducing the risk of adolescent drinking-and-driving behavior.

    Exposure to alcohol marketing is prevalent and is associated with both initiation and progression of alcohol use in underage youth. The mechanism of influence is not well understood, however. This study tests a model that proposes alcohol-specific cognitions as mediators of the relation between alcohol marketing and problematic drinking among experimental underage drinkers. This study describes a cross-sectional analysis of 1,734 U.S. 15- to 20-year-old underage drinkers, recruited for a national study of media and substance use. Subjects were queried about a number of alcohol marketing variables including TV time, Internet time, favorite alcohol ad, ownership of alcohol-branded merchandise (ABM), and exposure to alcohol brands in movies. The relation between these exposures and current (30-day) binge drinking was assessed, as were proposed mediators of this relation, including marketing-specific cognitions (drinker identity and favorite brand to drink), favorable alcohol expectancies, and alcohol norms. Paths were tested in a structural equation model that controlled for sociodemographics, personality, and peer drinking. Almost one-third of this sample of ever drinkers had engaged in 30-day binge drinking. Correlations between mediators were all statistically significant (range 0.16 to 0.47), and all were significantly associated with binge drinking. Statistically significant mediation was found for the association between ABM ownership and binge drinking through both drinker identity and having a favorite brand to drink, which also mediated the path between movie brand exposure and binge drinking. Peer drinking and sensation seeking were associated with binge drinking in paths through all mediators. Associations between alcohol marketing and binge drinking were mediated through marketing-specific cognitions that assess drinker identity and brand allegiance, cognitions that marketers aim to cultivate in the consumer.

    Hazardous drinking in emerging adulthood is associated with multiple domains of alcohol problems, which range in type and severity. Alcohol problems at the severe end of the spectrum (e.g., impaired control) may be early warning signs of alcohol use disorders (AUDs) among emerging adults. However, given the emphasis in the literature on predictors of overall problem risk, we still know very little about predictors of these specific (and severe) domains of alcohol problems in emerging adults. Many emerging adults drink at social events (e.g., parties), but an estimated 15% engage in solitary drinking. Solitary drinking - a developmentally atypical behavior in emerging adulthood - may be especially risky. Data suggests that frequent solitary drinking may reflect a loss of control over drinking, leading to hazardous use and subsequent problems. Accordingly, we expected that frequent solitary drinking among emerging adults would predict severe alcohol problems that map onto diagnostic criteria for AUDs and these effects would be mediated by hazardous alcohol use. Undergraduates (N=118) completed self-report measures as a part of a larger study on motivation and alcohol use. As predicted, path analysis showed that solitary drinking positively predicted hazardous alcohol use, and this in turn predicted severe alcohol problems associated with diagnostic criteria for AUDs, particularly risky behaviors and blackout drinking. Solitary drinking also positively predicted less severe problems of diminished self-perception and poor self-care through hazardous use. Though comparatively smaller, some indirect effects were observed from social drinking (at parties, but not at bars) to alcohol problems, via hazardous alcohol use. Overall, our results suggest that solitary drinking is particularly harmful in emerging adulthood. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    2012-10-01

    Full Text Available Abstract Background Use of energy drinks has significantly increased in recent times. Besides athletes, teenagers and students are among the most common consumers. However, popularity is also increasing among the younger and older age groups. Most of the users believe that they are a good source of instant energy and are unaware of its high Caffeine content resulting in harmful effects on health. Case presentation We report the case of a young boy who presented with palpitations and high blood pressure as a result of energy drinks usage. He had been consuming a “Sting” energy drink on regular basis while studying for long hours during his O’ level Exams. His medical examination revealed Sinus tachycardia and high blood pressure. Rest of the examination and lab workup was within normal limits. His pulse and blood pressure returned to normal range after discontinuing Sting usage. Conclusion Several studies have reported numerous health hazards including cardiac effects associated with energy drinks. Warning labeling should be done on these drinks regulating the content of Caffeine and its harmful effects on health.

    With the increase in popularity of energy drinks come multiple concerns about the associated health indicators of young people. The current study aims to describe the frequency of consumption of energy drinks in a nationally representative sample of adolescents and to explore the relationship between energy drink consumption and health risk behaviours, body size and mental health. Data were collected as part of Youth'12, a nationally representative survey of high school students in New Zealand (2012). In total, 8500 students answered a comprehensive questionnaire about their health and well-being, including multiple measures of mental well-being, and were weighed and measured for height. More than one-third (35%) of young people consumed energy drinks in the past week, and 12% consumed energy drinks four or more times in the past week. Energy drink consumption was significantly associated with greater depressive symptoms, greater emotional difficulties and lower general subjective well-being. Frequent energy drink consumption was also associated with binge drinking, smoking, engagement in unsafe sex, violent behaviours, risky motor vehicle use and disordered eating behaviours. There was no association between consumption of energy drinks and student body size. Consumption of energy drinks is associated with a range of health risk behaviours for young people. Strategies to limit consumption of energy drinks by young people are warranted. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    This study examines whether energy drink use and binge drinking predict sleep quantity, sleep quality, and next-day tiredness among college students. Web-based daily data on substance use and sleep were collected across four semesters in 2009 and 2010 from 667 individuals for up to 56 days each, yielding information on 25,616 person-days. Controlling for average levels of energy drink use and binge drinking (i.e., 4+ drinks for women, 5+ drinks for men), on days when students consumed energy drinks, they reported lower sleep quantity and quality that night, and greater next-day tiredness, compared to days they did not use energy drinks. Similarly, on days when students binge drank, they reported lower sleep quantity and quality that night, and greater next-day tiredness, compared to days they did not binge drink. There was no significant interaction effect between binge drinking and energy drink use on the outcomes.

    This study examined the relative importance of climate change and drinking-water treatment for gastrointestinal illness incidence in children (age drinking-water sources or into leaking water-distribution networks. Building on observed relationships, the second analysis projected how climate change and drinking-water treatment installation may alter gastrointestinal illness incidence. Future precipitation values were modeled by 13 global climate models and three greenhouse-gas emissions levels. The second analysis was rerun using three pathways: (1) only climate change, (2) climate change and the same slow pace of treatment installation observed over 1991-2010, and (3) climate change and the rapid rate of installation observed over 2011-2016. The results illustrate the risks that climate change presents to small rural groundwater municipalities without drinking water treatment. Climate-change-related seasonal precipitation changes will marginally increase the gastrointestinal illness incidence rate (mean: ˜1.5%, range: -3.6-4.3%). A slow pace of treatment installation somewhat decreased precipitation-associated gastrointestinal illness incidence (mean: ˜3.0%, range: 0.2-7.8%) in spite of climate change. The rapid treatment installation rate largely decreases the gastrointestinal illness incidence (mean: ˜82.0%, range: 82.0-83.0%).

    The purpose of drinking water legislation is to guarantee the quality and safety of water intended for human consumption. In the European Union, Directive 98/83/EC updated the essential and binding quality criteria and standards, incorporated into Spanish national legislation by Royal Decree 140/2003. This article reviews the main characteristics of the aforementioned drinking water legislation and its impact on the improvement of water quality against empirical data from Catalonia. Analytical data reported in the Spanish national information system (SINAC) indicate that water quality in Catalonia has improved in recent years (from 88% of analytical reports in 2004 finding drinking water to be suitable for human consumption, compared to 95% in 2014). The improvement is fundamentally attributed to parameters concerning the organoleptic characteristics of water and parameters related to the monitoring of the drinking water treatment process. Two management experiences concerning compliance with quality standards for trihalomethanes and lead in Barcelona's water supply are also discussed. Finally, this paper presents some challenges that, in the opinion of the authors, still need to be incorporated into drinking water legislation. It is necessary to update Annex I of Directive 98/83/EC to integrate current scientific knowledge, as well as to improve consumer access to water quality data. Furthermore, a need to define common criteria for some non-resolved topics, such as products and materials in contact with drinking water and domestic conditioning equipment, has also been identified.

    Full Text Available The hamster check pouch is an invagination of oral mucosa, characterized histologically as skin-like. In this paper we describe anatomical, histological and embriological features of the pouch and coment on the pouch as an immunologically privileged site since it lacks lymphatic drainage and has few Langerhans cells. We present the review from literature and our observations after inoculation in the pouch of mycobacteriae (BCG, Mycobacterium tuberculosis and Mycobacterium leprae and a fungus (Paracoccidioides brasiliensis. Lesions in the pouch were granulomatous but smaller and long lasting; even granulomatous, the reaction was inefficient to control the proliferation of agents compared with inoculation in other sites, except for BCG. Appearance of immunity was also delayed or absent and, when it was detected, a sharp decrease in number of agents in pouch lesions was observed. These observations make the pouch an interesting site for the study of the role of immune system in infeccious diseases and in granuloma formation.A bolsa jugal do hamster (BJH é uma invaginação da mucosa oral, caracterizada histologicamente como semelhante a pele.

    An atrial septal pouch (ASP) results from partial fusion of the septum primum and the septum secundum, and depending on the site of fusion, the pouch can be left-sided (LASP) or right-sided (RASP). LASPs have been described in association with thrombi found in patients admitted with acute strokes, raising awareness of its potential cardioembolic role, especially in those with no other clearly identifiable embolic source. We retrospectively studied 39 patients in whom the presence of an ASP had been identified by three-dimensional transesophageal echocardiography (3DTEE) and who had a two-dimensional transesophageal echocardiogram (2DTEE) performed during the same clinical encounter. The incremental value provided by 3DTEE over 2DTEE included the detection of six ASPs not found by 2DTEE; the detection of two ASPs in the same subject (in four patients) not identified by 2DTEE; larger ASP measurements of length and height in over 80% of the cases; and measurement of the ASP width (elevational axis) for the calculation of the area of the ASP opening, because of its unique capability to view the pouch en face. In addition, the volume of ASP and of the echogenic masses contained in the ASP (four of 39 patients) could be calculated by 3DTEE, which is a superior parameter of size characterization when compared to individual dimensions. One of these patients who presented with ischemic stroke diagnosed by magnetic resonance imaging had a large (>2 cm) mass in a LASP, with echolucencies similar to those seen in thrombi and associated with clot lysis and resolution. This mass completely disappeared on anticoagulant therapy lending credence that it was most likely a thrombus. There was no history of stroke or any other type of embolic event in the other three patients with masses in ASP. In conclusion, this retrospective study highlights the incremental value of 3DTEE over 2DTEE in the comprehensive assessment and characterization of ASPs, which can aid in the clarification of

    Caffeinated energy drinks have become increasingly popular among young people, raising concern about possible adverse effects, including increased alcohol consumption and related risk behaviours. The current study examined consumption of caffeinated energy drinks and use of energy drinks with alcohol, as well as associations with socio-demographic and behavioural characteristics, among a sample of secondary school students in Ontario. Survey data from 23,610 grade 9-12 students at 43 purposefully sampled Ontario secondary schools participating in the baseline wave (2012/13) of the COMPASS study were analyzed using generalized linear mixed-effects models. Outcomes were any energy drink use, frequency of use, and use of alcohol mixed with energy drinks; covariates were age, sex, race, spending money, bodymass index (BMI), weight-related efforts and alcohol use. Two-way interactions between sex and other covariates were tested. Nearly one in five students (18.2%) reported consuming energy drinks in a usual week. Use of energy drinks was associated (p < 0.01) with all socio-demographic variables examined and was more common among students who were male, off-reserve Aboriginal, had some spending money, had a BMI outside of "healthy" range, were trying to lose weight, and/or reported a higher intensity of alcohol use. Interactions with sex were observed for age, spending money and weight-related efforts. Use of energy drinks mixed with alcohol in the previous 12 months was reported by 17.3% of the sample, and was associated with race, spending money, and more frequent binge drinking. Regular use of energy drinks was common among this sample of students and strongly linked to alcohol consumption.

    Context: The sensation of thirst is different from the complex behavior of drinking ad libitum. Rehydration recommendations to athletes differ, depending on the source, yet no previous researchers have systematically compared drinking to thirst (DTT) versus ad libitum drinking behavior (DAL). Objective: To compare 2 groups of trained cyclists (DTT and DAL) who had similar physical characteristics and training programs (P > .05). The DTT group (n = 12, age = 47 ± 7 years) drank only when thirsty, whereas the DAL group (n = 12, age = 44 ± 7 years) consumed fluid ad libitum (ie, whenever and in whatever volume desired). Design: Cohort study. Setting: Road cycling (164 km) in the heat (36.1°C ± 6.5°C). Patients or Other Participants: Ultraendurance cyclists (4 women, 20 men). Intervention(s): We recorded measurements 1 day before the event, on event day before the start, at 3 roadside aid stations, at the finish line, and 1 day after the event. Main Outcome Measure(s): Body mass, urinary hydration indices, and food and fluids consumed. Results: No between-groups differences were seen on event day for total exercise time (DTT = 6.69 ± 0.89 hours, DAL = 6.66 ± 0.77 hours), urinary indices (specific gravity, color), body mass change (DTT = −2.22% ± 1.73%, DAL = −2.29% ± 1.62%), fluid intake (DTT = 5.63 ± 2.59 L/6.7 h, DAL = 6.04 ± 2.37 L/6.7 h), dietary energy intake, macronutrient intake, ratings of thirst (DTT start = 2 ± 1, DTT finish = 6 ± 1, DAL start = 2 ± 1, DAL finish = 6 ± 1), pain, perceived exertion, or thermal sensation. Total fluid intake on recovery day +1 was the primary significant difference (DAL = 5.13 ± 1.87 L/24 h, DTT = 3.13 ± 1.53 L/24 h, t18 = 2.59, P = .02). Conclusions: Observations on event day indicated that drinking to thirst and drinking ad libitum resulted in similar physiologic and perceptual outcomes. This suggests that specific instructions to “drink to thirst” were unnecessary. Indeed, if athletes drink ad libitum

    Drinking patterns of 245 college students (88 boys and 157 girls) were surveyed by using modified questionnaire of Hirayama's 18 years ago survey and the principal results were as follows. 1. The increased tendencies of the drinking of the girl students were found here and there. 2. The principal favorite drinking places of the college students were the popular taverns (YAKITORI-YA, ODEN-YA etc.).3. The doubts or tendencies of alcohol dependence of the college students were small as the results of Hirayama's 18 years ago survey. 4. The first age of drinking tends to lower. The principal purpose of drinking of the college students was social intercourse and the motive of the drinking was principally solicitation by others and the sincere lovers of drinking were unexpectedly a few similar to Hirayama's survey. So, the counterplans to drinking habits and the alcoholism among college students should be considered from the social point of view as before.

    2013-01-01

    Social host policies focused on underage drinking parties are implemented to reduce social availability of alcohol and high-risk drinking by adolescents in private locations. We examined the policies' relationship with drinking location, peer-group drinking size, heavy episodic drinking, and nonviolent consequences. Cross-sectional data from 11,205, 14-20-year olds, were analyzed using multilevel modeling. Policies were not associated with drinking location, decreased heavy episodic drinking, or nonviolent consequences. However, adolescents from communities with a preexisting policy had lower odds of drinking in large peer groups compared to those from communities without a policy at baseline. Additional research is needed to examine their effectiveness. The study's limitations are noted.

    This study aimed to investigate alcoholic beverages drinking and predictive factors among female students. The participants were 377 subjects from 3 high schools in a tourist province, of Thailand. Data collection was done through self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from 0.84 - 0.88. The data were analyzed by using descriptive and inferential statistics. The findings revealed as follows. About half (51%) of them have ever drunk and 10.5% of drinkers have drunk once a week. In addition, 15.6% of drinkers began their first drink when they were under 10 years old. Risk factors for alcohol consumption of female student were age, GPA, drinker in family, peer pressure, advertisement and accessibility to alcoholic beverages while protective factors were perception of drinking impacts on family and moral values. Students who have a drinking family member were 4.6 times more likely to drink than those who do not have.

    2015-03-01

    Daily data collected over 14 consecutive days were used to examine whether extreme drinking was more likely on days college students reported prepartying (i.e., drinking before going out) or playing drinking games in a multi-ethnic sample of college seniors (analysis subsample: N=399; 57% women; M age=21.48years, SD=.40). Multilevel modeling with drinking occasions at Level 1 (1265 drinking days) nested within persons at Level 2 (399 drinkers) was used to predict four extreme drinking behavior outcomes at the daily level: consuming at least 8/10 (women/men) drinks, reaching an estimated blood alcohol concentration (eBAC) of .16% or greater, drinking enough to stumble, and drinking enough to pass out. Prepartying only (29% of drinking days) was more common than playing drinking games only (10%) or engaging in both behaviors on the same day (13%). Odds of extreme drinking were greater among students who frequently engaged in prepartying (ORs: 1.86-2.58) and drinking games (ORs: 1.95-4.16), except prepartying frequency did not predict drinking enough to pass out. On days students prepartied (ORs: 1.58-2.02) and on days they played drinking games (ORs: 1.68-1.78), odds of extreme drinking were elevated, except drinking games did not predict eBAC of .16% or greater. Extreme drinking is attributable to both person-level characteristics (e.g., preparty frequency) and specific drinking behaviors on a given day. Prepartying and drinking games confer elevated risk of extreme drinking and are important targets in alcohol interventions for college seniors. Copyright © 2014 Elsevier Ltd. All rights reserved.

  8. Solitary and social heavy drinking, suicidal ideation, and drinking motives in underage college drinkers.

    Gonzalez, Vivian M; Collins, R Lorraine; Bradizza, Clara M

    2009-12-01

    In college students, solitary heavy drinking (i.e., while alone) is associated with depression and with higher rates of drinking problems than heavy drinking in social contexts. This study explored the relationship among heavy episodic drinking context, suicidal ideation, and drinking motives among underage college drinkers (n=91) with a history of passive suicidal ideation. Participants completed measures of depression, suicidal ideation, alcohol consumption and problems, and drinking motives. Multiple regression analyses revealed that suicidal ideation, but not depression, was significantly related to solitary heavy drinking. Neither was related to social heavy drinking. Enhancement motives for drinking, but not other drinking motives (i.e., social, conformity, drinking to cope), were significantly associated with social heavy drinking. In contrast, only drinking to cope was associated with solitary heavy drinking. These findings suggest that greater suicidal ideation is associated with greater frequency of becoming intoxicated while alone, and that this drinking is motivated by attempts to cope. Solitary heavy drinking is a potentially dangerous coping strategy for an individual experiencing suicidal ideation.

    What is the inter-/intra-observer agreement and diagnostic accuracy among gynaecological and non-gynaecological ultrasound specialists in the prediction of pouch of Douglas (POD) obliteration (secondary to endometriosis) at offline analysis of two-dimensional videos using the dynamic real-time transvaginal ultrasound (TVS) 'sliding sign' technique? The inter-/intra-observer agreement and diagnostic accuracy for the interpretation of the TVS 'sliding sign' in the prediction of POD obliteration was found to be very acceptable, ranging from substantial to almost perfect agreement for the observers who specialized in gynaecological ultrasound. Women with POD obliteration at laparoscopy are at an increased risk of bowel endometriosis; therefore, the pre-operative diagnosis of POD obliteration is important in the surgical planning for these women. Previous studies have used TVS to predict POD obliteration prior to laparoscopy, with a sensitivity of 72-83% and specificity of 97-100%. However, there have not been any reproducibility studies performed to validate the use of TVS in the prediction of POD obliteration pre-operatively. This was a reproducibility study which involved the offline viewing of pre-recorded video sets of 30 women presenting with chronic pelvic pain, in order to determine POD obliteration using the TVS 'sliding sign' technique. The videos were selected on real-time representative quality/quantity; they were not obtained from sequential patients. There were a total of six observers, including four gynaecological ultrasound specialists and two fetal medicine specialists. The study was conducted over a period of 1 month (March 2012-April 2012). The four gynaecological ultrasound observers performed daily gynaecological scanning, while the other two observers were primarily fetal medicine sonologists. Each sonologist viewed the TVS 'sliding sign' video in two anatomical locations (retro-cervix and posterior uterine fundus), i.e. 60 videos in total. The

    Background Exposure to alcohol marketing is prevalent and is associated with both initiation and progression of alcohol use in underage youth. The mechanism of influence is not well understood, however. This study tests a model that proposes alcohol-specific cognitions as mediators of the relation between alcohol marketing and problematic drinking among experimental underage drinkers. Methods This paper describes a cross-sectional analysis of 1734 U.S. 15–20 year old underage drinkers, recruited for a national study of media and substance use. Subjects were queried about a number of alcohol marketing variables including television time, internet time, favorite alcohol ad, ownership of alcohol branded merchandise (ABM), and exposure to alcohol brands in movies. The relation between these exposures and current (30 day) binge drinking was assessed, as were proposed mediators of this relation, including marketing-specific cognitions (drinker identity and favorite brand to drink), favorable alcohol expectancies and alcohol norms. Paths were tested in a structural equation model that controlled for socio-demographics, personality and peer drinking. Results Almost one-third of this sample of ever drinkers had engaged in 30 day binge drinking. Correlations among mediators were all statistically significant (range 0.16 – 0.47) and all were significantly associated with binge drinking. Statistically significant mediation was found for the association between ABM ownership and binge drinking through both drinker identity and having a favorite brand, which also mediated the path between movie brand exposure and binge drinking. Peer drinking and sensation seeking were associated with binge drinking in paths through all mediators. Conclusions Associations between alcohol marketing and binge drinking were mediated through marketing-specific cognitions that assess drinker identity and brand allegiance, cognitions that marketers aim to cultivate in the consumer.

    This study examined associations between workers' reported exposure to occupational hazards and at risk drinking. A sample of 15,907 working adults was drawn from the 1985 National Health Interview Survey (NHIS) (weighted sample represented 85,395,000 workers). This was the only year the NHIS included questions on both occupational hazard exposure and at risk drinking. Occupational hazard exposures included chemical/biological substances, physical hazards, injury risk, and mental stress. At risk drinking was defined as binge drinking and drinking and driving. Prevalence adjusted odds ratios were estimated. Sixty percent of workers reported exposure to one or more occupational hazards with considerable variation among and within occupations. In all, 31% reported binge drinking and 15% drove after drinking too much. In a multivariate analysis that controlled for background characteristics, workers who reported occupational hazard exposures were 1.2 to 1.4 times more likely to engage in binge drinking than workers without exposures. Similar results were found for drinking/driving. All multivariate results were statistically significant. Findings suggest workers who report occupational hazard exposures are at greater risk of both binge drinking and drinking/driving. Occupational and environmental health nurses can lead workplace initiatives to reduce occupational hazard exposure and, simultaneously, invest in health promotion efforts to curb at risk drinking among workers.
