Factors affecting food waste: a bibliometric review on the household behaviors
No full textSustainability issues such as food insecurity, climate change, land degradation, economic
development and food waste are the actual most important challenges at the global level.
Among them, the food waste (FW) challenge has a great magnitude, emphasizing the
importance of examining this issue. Specifically, there is a need to focus on the household
level. Thus, this study aims to investigate and identify the main factors influencing FW
household behaviors on which policymakers and stakeholders could outline specific and
sustainable strategies. Starting from a large number of published studies on this subject
with a similar aim but focusing on specific Countries or contexts, the goal of our study is
achieved through the implementation of a systematic literature review followed by a bibliometric review using the VOSviewer software. The selected query generated a total of 235
matching papers from which only 111 papers were collected for the bibliometric review
because of the inclusion criteria. The analysis showed the existence of four major research
strands: the largest one analyses the antecedents of behavior during food management,
including the implementation of the Theory of Planned Behavior (TPB). Other detected topics are the economic impact of FW, the effects generated by the Covid-19 pandemic on consumer behaviors, and finally, the environmental and social effects of FW. The objective of
this study is to investigate and identify the main factors influencing FW household behaviors.
The obtained output represents useful information for policymakers and stakeholders to outline specific and sustainable strategies to reduce FW
Small bowel obstruction after gastric by-pass: Diagnostic limits and percutaneous drain. A paradigmatic case
No full textBackground: Obesity is showing a constant increase worldwide, making it the major public health problem. Bariatric surgery seems to be the best treatment for these to achieve a good excess weight loss. Gastric by-pass (GBP) is one the most important bariatric procedure, but there are a lot of complications as bowel obstruction for internal hernia, fistula and intussusception. Case report: We present a peculiar case report of a 53-years old woman that underwent to GBP. On the fourth postoperative day, she presented a bowel obstruction and underwent a second surgical intervention for incisional hernia. Another surgical revision was necessary because of dilatation of excluded stomach. Subsequent external drain of excluded stomach solved the paralytic ileum post bowel obstruction. Conclusion: Postoperative occlusion is more complex in bariatric patients, either for variety of etiology, either for choosing best approach to the new anatomy. In addition, post-surgery course may be different, because GBP may determine many modifications on gastrointestinal motility and clinical symptoms. An accurate knowledge of bariatric surgery is mandatory in these situations, obtaining the best management
Is the Sleeve Gastrectomy Always a Better Procedure? Five-Year Results from a Retrospective Matched Case-Control Study
No full textIntroduction: Bariatric surgery is considered the most effective treatment for obesity. A recent worldwide survey demonstrated that Laparoscopic Sleeve Gastrectomy (LSG) is the most commonly performed bariatric procedure, while Laparoscopic Adjustable Gastric Banding (LAGB) has been almost abandoned. Objectives: The aim of this retrospective study was to compare 5-year results of LSG and LAGB at our Institution. Materials and Methods: Prospective maintained database of our Institution was reviewed to find all patients who had undergone LSG between January 2009 and December 2011. Inclusion criteria were BMI of 40–50 kg/m2 and age of 18–60 years old. Patients with Class I and II obesity, superobese subjects, and patients with previous history of bariatric surgery were excluded. Data on sex, age, pre-operative BMI, obesity-related diseases (diabetes, hypertension, dyslipidemia), and early and late complications were collected. Each subject who underwent LSG was matched one-to-one with a patient that had undergone LAGB. Outcomes were analyzed at 1, 3, and 5 years of follow-up. Results: A total number of 122 patients were included in this study, 61 in each group. Better %EWL was observed in the LSG group at 1, 3, and 5 years. Both procedures induced improvements of obesity-related diseases without significant difference. In the LAGB group, ten patients underwent uneventful band removal. In the LSG group, two patients had serious postoperative complications. Conclusion: LSG achieves better %EWL than LAGB within 5 years, but comorbidities improvement is not significantly different. Severity of complication is higher after LSG. LAGB is still a good option for selected patients
Abdominoplasty after bariatric surgery: Comparison of three different techniques
No full textBACKGROUND: Abdominoplasty after massive weight loss is not a cosmetic procedure. The aim of this study was to compare three different techniques for postbariatric abdominoplasty. METHODS: All postbariatric patients that have undergone abdominoplasty from January 2013 to December 2016 were included in the study. Patients were divided into 3 groups: Subjects who underwent standard procedure were allocated ingroup A; those cases performed using a synthetic glue were assigned to group B; cases performed with an energy device were inserted in group C. Operative time, length of stay and complications were recorded. RESULTS: Seventy-one abdominoplasties were performed in the selected period. Mean operative time was shorter (P<0.01) in group C (94.3±2.7 minutes) than in group A(112.1±16.8 minutes) and in group B (121±13.2 minutes). Mean length of stay was significantly reduced (P<0.01) in group C (2.4±0.7) when compared to group A (3.5±0.6 days) and group B (3.1±0.5 days). Bleeding occurred in 21 (29.5%) patients (15 in group A, 4 in groupB, 3 in group C; P<0.01). Seroma was detected in 22(30.9%) subjects (14 in group A, 2in group B, 6 in group C; P<0.01). Wound dehiscence and umbilical necrosis were recorded in 7 (9.9%) and 9 (12.6%) patients respectively, without statistical differences. CONCLUSIONS: Both synthetic glue and energy device improve outcomes of postbariatric abdominoplasties. The glue reduces rates of bleeding and seroma. The energy deviceimproves intraoperative hemostasis and shortens operative time. copy
May Bioelectrical Impedance Analysis Method Be Used in Alternative to the Dual-Energy X-Ray Absorptiometry in the Assessment of Fat Mass and Fat-Free Mass in Patients with Obesity? Pros, Cons, and Perspectives
No full textObesity and periodontal disease: A narrative review on current evidence and putative molecular links
No full textBackground: Obesity represents one of the main health problems worldwide and is considered a risk factor for several diseases, including periodontitis, which is a microbially-associated inflammatory disease affecting the tooth-supporting structures. Objective: The aim of this review was to report the current direct and indirect evidence concerning the possible association between obesity and periodontitis and their putative molecular links. Methods: A literature search was conducted between January 1999 and September 2019, in PubMed/MEDLINE and Science Direct databases, using pertinent keyword combined by Boolean operators. Through a multi-step screening process (literature search; articles title and abstract evaluation and full-text reading), studies fitting inclusion/exclusion criteria were considered for the review. Results: 35 studies were included in the present review (17 observational studies; 7 systematic reviews; 11 systematic reviews with meta-analysis), focusing on the direct and indirect evidence of the possible association between obesity and periodontitis and their potential etiopathogenic molecular links Conclusion: Although the majority of the studies reported a positive association between obesity and periodontitis, the heterogeneity of the classification criteria and of the clinical parameters employed in the studies for both obesity and periodontitis evaluation, complicated the comparison of the results, thus considered inconclusive. Although several putative molecular pathogenic links between obesity and periodontitis have been highlighted, further studies, with longer follow-ups and with homogeneous clinical criteria, are needed to better understand the putative relation between obesity and periodontal disease
Twisted Gastric Tube after Laparoscopic Sleeve Gastrectomy—An Unusual but Effective Surgical Approach to Achieve Full Recovery
No full textSleeve gastrectomy is at present the most practiced bariatric intervention for patients suffering from severe obesity. Although rare, post-operative complications such as leakages and strictures may represent a challenging issue for bariatric surgeons and cause impaired quality of life for patients. Gastric twist is even more rare. This complication is a functional obstruction rather than a stricture of the gastric remnant most likely due to technical mistakes at index surgery. If endoscopy usually allows diagnosis and constitutes the first-line treatment for this condition, surgery is mandatory when endoscopy is not successful. The conversion of the sleeve to a Roux-en-Y gastric bypass is the usually chosen intervention but a wide range of reconstruction has been proposed. In this report, we discuss the surgical technique we employed to achieve a full resolution of a gastric twist
Gastric cancer following bariatric surgery: a review.
No full textBACKGROUND:: Bariatric procedures can induce a massive weight loss that lasts for >15 years after surgery; in addition, they achieve important metabolic effects including diabetes resolution in the majority of morbidly obese patients. However, some bariatric interventions may cause gastroesophageal reflux disease and other serious complications. The aim of our study is to evaluate the risk of cancer after bariatric surgery. METHODS:: We conducted a review of the literature about the cases of gastric cancer arising after any bariatric procedure, including a case of adenocarcinoma incidentally discovered by the authors 6 months after laparoscopic adjustable gastric banding. RESULTS:: Globally, 17 case reports describing 18 patients were retrieved, including the case study by the authors. The diagnosis of tumor was at a mean of 8.6 years after bariatric surgery, 9.3 years after RYGB, and 8.1 years after restrictive procedures. The adenocarcinoma represented most cases (15 patients, 83%). In the patients with RYGB, the adenocarcinoma was localized in the excluded stomach in 5 patients (83%) and in the pouch in 1 patient (17%). After a restrictive procedure, the cancer was localized in the pouch in 5 patients (62.5%), in the pylorus in 2 patients (25%), and in lesser curvature only in 1 patient (12.5%). CONCLUSIONS:: There is a lack of evidence about a connection between the late occurrence of gastric adenocarcinoma and the bariatric surgery. For this reason, although the preoperative upper endoscopy is still mandatory, there is no need for a regular endoscopic evaluation of patients after surgery. © 2014 by Lippincott Williams & Wilkins.BACKGROUND:
