- Surgical site infection (SSI) is one of the most common healthcare-associated infections (HAIs). However, there is a lack of data available about SSI in children worldwide, especially from low-income and middle-income countries. This study aimed to estimate the incidence of SSI in children and associations between SSI and morbidity across human development settings.MethodsA multicentre, international, prospective, validated cohort study of children aged under 16 years undergoing clean-contaminated, contaminated or dirty gastrointestinal surgery. Any hospital in the world providing paediatric surgery was eligible to contribute data between January and July 2016. The primary outcome was the incidence of SSI by 30 days. Relationships between explanatory variables and SSI were examined using multilevel logistic regression. Countries were stratified into high development, middle development and low development groups using the United Nations Human Development Index (HDI).ResultsOf 1159 children across 181 hospitals in 51 countries, 523 (45·1%) children were from high HDI, 397 (34·2%) from middle HDI and 239 (20·6%) from low HDI countries. The 30-day SSI rate was 6.3% (33/523) in high HDI, 12·8% (51/397) in middle HDI and 24·7% (59/239) in low HDI countries. SSI was associated with higher incidence of 30-day mortality, intervention, organ-space infection and other HAIs, with the highest rates seen in low HDI countries. Median length of stay in patients who had an SSI was longer (7.0 days), compared with 3.0 days in patients who did not have an SSI. Use of laparoscopy was associated with significantly lower SSI rates, even after accounting for HDI.ConclusionThe odds of SSI in children is nearly four times greater in low HDI compared with high HDI countries. Policies to reduce SSI should be prioritised as part of the wider global agenda.

COVID-19 Vaccine Acceptance among Social Media Users : A Content Analysis, Multi-Continent Study
- 2022
-
In: International Journal of Environmental Research and Public Health. - : MDPI AG. - 1661-7827 .- 1660-4601. ; 19:9
-
Journal article (peer-reviewed)abstract
- Vaccine hesitancy (VH) is defined as a delayed in acceptance or refusal of vaccines despite availability of vaccination services. This multinational study examined user interaction with social media about COVID-19 vaccination. The study analyzed social media comments in 24 countries from five continents. In total, 5856 responses were analyzed; 83.5% of comments were from Facebook, while 16.5% were from Twitter. In Facebook, the overall vaccine acceptance was 40.3%; the lowest acceptance rates were evident in Jordan (8.5%), Oman (15.0%), Senegal (20.0%) and Morocco (20.7%) and the continental acceptance rate was the lowest in North America 22.6%. In Twitter, the overall acceptance rate was (41.5%); the lowest acceptance rate was found in Oman (14.3%), followed by USA (20.5%), and UK (23.3%) and the continental acceptance rate was the lowest in North America (20.5%), and Europe (29.7%). The differences in vaccine acceptance across countries and continents in Facebook and Twitter were statistically significant. Regarding the tone of the comments, in Facebook, countries that had the highest number of serious tone comments were Sweden (90.9%), USA (61.3%), and Thailand (58.8%). At continent level, serious comments were the highest in Asia (58.4%), followed by Africa (46.2%) and South America (46.2%). In Twitter, the highest serious tone was reported in Egypt (72.2%) while at continental level, the highest proportion of serious comments was observed in Asia (59.7%), followed by Europe (46.5%). The differences in tone across countries and continents in Facebook and Twitter and were statistically significant. There was a significant association between the tone and the position of comments. We concluded that the overall vaccine acceptance in social media was relatively low and varied across the studied countries and continents. Consequently, more in-depth studies are required to address causes of such VH and combat infodemics.

Photo- and Electrochemical Dual-Responsive Iridium Probe for Saccharide Detection
- 2022
-
In: Chemistry - A European Journal. - 0947-6539 .- 1521-3765. ; 28
-
Journal article (peer-reviewed)abstract
- Dual detection systems are of interest for rapid, accurate data collection in sensing systems and in vitro testing. We introduce an IrIII complex with a boronic acid receptor site attached to the 2-phenylpyridine ligand as an ideal probe with photo- and electrochemical signals that is sensitive to monosaccharide binding in aqueous solution. The complex displays orange luminescence at 618 nm, which is reduced by 70 and 40 % upon binding of fructose and glucose, respectively. The electro-chemiluminescent signal of the complex also shows a direct response to monosaccharide binding. The IrIII complex shows the same response upon incorporation into hydrogel matrices as in solution, thus demonstrating the potential of its integration into a device, as a nontoxic, simple-to-use tool to observe sugar binding over physiologically relevant pH ranges and saccharide concentrations. Moreover, the complex's luminescence is responsive to monosaccharide presence in cancer cells.

Factors associated with complete and partial remission, improvement, or unchanged diabetes status of obese adults 1 year after sleeve gastrectomy
- 2020
-
In: Surgery for Obesity and Related Diseases. - : Elsevier. - 1550-7289 .- 1878-7533. ; 16:10, s. 1521-1530

Journal article (peer-reviewed)abstract
- Background: Laparoscopic sleeve gastrectomy (SG) achieves type 2 diabetes (T2D) remission to various extents, and reasons for such variations are unknown. Objectives: We assessed patients’ characteristics associated with T2D remission 1 year post SG. Setting: University hospital. Methods: Retrospective study of 230 T2D patients (18–64 yr) who underwent SG at our institution. We examined pre- and postoperative demographic, anthropometric, biochemical, and clinical characteristics associated with T2D complete remission, partial remission, improvement, or unchanged status. Independent predictors of T2D complete remission were assessed by binary logistic regression and then included in 7 predictive models. Logistic regression assessed the pre- and postoperative predictors of T2D complete remission and their predictive performance was measured with the area under the curve of the receiver operating characteristic curve. Results: A total of 230 patients were included in the study, females comprised 69%, and mean age was 45.66 ± 8.84 years. Mean preoperative weight and body mass index were 115.69 ± 20.76 kg and 43.53 ± 6.98 kg/m2, respectively. Approximately two thirds (64.4%) of the sample had diabetes for >5 years. Insulin therapy users comprised 36.9% of the sample and 29.6% of patients were on ≥2 oral hypoglycemic agents (OHA). At 1 year, mean body mass index was 32.77 ± 6.09 kg/m2, percent excess weight loss (%EWL) was 62.29 ± 23.60% and glycosylated hemoglobin (HbA1C) improved from 8.1% to 6.18%. Approximately 42.2% of the sample achieved T2D complete remission. Compared with those with no remission, patients with complete remission were significantly younger, had shorter duration of diabetes, were not on insulin therapy, took fewer OHA, had higher C-peptide, lower preoperative HbA1C, were less likely to have had hypertension or dyslipidemia, and more likely to have achieved higher %EWL. Seven proposed models for prediction of complete remission showed the most useful model comprised diabetes duration + pre-HbA1C + %EWL + insulin therapy + age + OHA (area under the curve = .81). Independent predictors of complete remission were preoperative HbA1C, %EWL, insulin therapy, age, and OHA (but not diabetes duration). Conclusion: SG results in significant weight reduction and various extents of T2D remission. HbA1C, %EWL, insulin therapy, age, and OHA were independent predictors of complete remission. Assessing these factors before bariatric surgery is important to identify any modifiable characteristics that can be altered to increase the likelihood of remission. © 2020 American Society for Bariatric Surgery

Evolution of 29 Anthropometric, Nutritional, and Cardiometabolic Parameters Among Morbidly Obese Adolescents 2 Years Post Sleeve Gastrectomy
- 2018
-
In: Obesity Surgery. - : Springer. - 0960-8923 .- 1708-0428. ; 28:2, s. 474-482
-
Journal article (peer-reviewed)abstract
- Background Laparoscopic sleeve gastrectomy (LSG) is a popular treatment for adolescent morbid obesity. Research on LSG outcomes among adolescents assessed a narrow range of anthropometric, nutritional, or cardiometabolic parameters, leading to an incomplete picture of these changes. We examined a wide variety of anthropometric, nutritional, and cardiometabolic parameters among adolescents before and after LSG. Methods We retrospectively reviewed medical charts of all obese adolescents who underwent LSG at Hamad Medical Corporation, Qatar, between January 2011 and June 2015 (N = 102). We assessed preoperative levels and postoperative changes in 4 anthropometric, 15 nutritional, and 10 cardiometabolic parameters. Results The study sample comprised 79 patients with complete information (36 males, mean age 15.99 +/- 1.1 years). At a mean of 24.2 months post-LSG, we observed (1) significantly reduced mean weight and body mass index by 51.82 +/- 28.1 kg and 17 +/- 6.24 kg/m(2), respectively; (2) the highest prevalence of post-LSG deficiencies pertained to vitamin D, albumin, and ferritin (89.3, 38, and 33.3%, respectively); (3) low hemoglobin levels (29.3%) only in females; (4) trace elements were not deficient; (4) significant reductions in percentage of adolescents with elevated low-density lipoprotein (from 66.1 to 38.9%), alanine aminotransferase (from 45.3 to 10.9%), and aspartate aminotransferase (from 24.1 to 8.6%) levels; (5) 100% remission of prediabetes cases; and (6) 80% remission of type 2 diabetes cases. Conclusions LSG achieved significant weight loss and improvement of cardiometabolic risk factors among adolescents. However, the slight worsening of preexisting nutritional deficiencies warrants careful preoperative surveillance and appropriate postoperative nutritional supplementation.

Lorcaserin vs. Phentermine among non-surgical and surgical obese patients : Anthropometric, glycemic, lipid, safety and cost outcomes
- 2019
-
In: Annals of Medicine and Surgery. - : Elsevier. - 2049-0801. ; 45, s. 75-81
-
Journal article (peer-reviewed)abstract
- Background: To evaluate effectiveness, safety, and costs of Lorcaserin vs. phentermine among obese non–surgical and surgical patients (post bariatric surgery). Methods: This retrospective study retrieved charts of all patients (January 2013–June 2016) who received Lorcaserin or phentermine for 3 months. The study assessed anthropometric, glycemic, and lipid changes, as well as side effects and cost of medications among overweight and obese non-surgical (n = 83) and surgical patients (n = 46). These two patient groups were compared using Chi-square (χ2) and unpaired‘t’ test for qualitative and quantitative variables respectively. Results: At 3 months, among the non-surgical group, Phentermine patients had greater percentage of total weight loss (TWL%) (7.65 ± 8.26 vs. 2.99 ± 3.72%, P = 0.003), and greater BMI reduction (−3.16 ± 3.63 vs. −1.15 ± 1.53 kg/m2, P = 0.003) than Lorcaserin. Within the surgical group, Lorcaserin patients had significantly smaller TWL% (1.86 ± 5.06 vs. 7.62 ± 9.80%, P = 0.012), and smaller BMI reduction (−0.74 ± 1.80 vs. −3.06 ± 4.08 kg/m2, P = 0.012) than Phentermine. Lorcaserin exhibited significant total cholesterol and LDL improvements only among surgical patients with significant weight reduction (≥5% TW). Both medications were not associated with glycemic improvements among non-surgical and surgical groups. Phentermine had slightly more side effects but was less expensive. Conclusions: Among both patient groups, phentermine was more effective in achieving weight loss. Lorcaserin showed dyslipidemia improvements only among surgical patients who achieved significant weight reduction. Anti-obesity medications as part of weight management programs can result in weight loss among non-surgical and surgical patients, or halt weight regain among surgical patients. This is the first study to evaluate the effectiveness and safety of two anti-obesity medications (lorcaserin vs. phentermine) among two distinct obese patient groups, non-surgical and surgical patients.
