The actual Continual Renal Illness inside Africa (CKD-Africa) venture: training coming from a brand new pan-African community.
PURPOSE We investigated the association between gastric cancer and environmental and dietary exposures. In addition, we explored probable mechanistic pathways for the influence of biomass smoke on gastric carcinogenesis. PATIENTS AND METHODS The study was conducted in Lusaka, Zambia. Questionnaires were used to collect data on risk factors, whereas enzyme-linked immunosorbent assays and high-performance liquid chromatography were used to measure biologic exposures. Study data were analyzed using contingency tables and logistic regression. RESULTS We enrolled 72 patients with gastric adenocarcinoma and 244 controls. Gastric cancer was positively associated with rural residence (odds ratio [OR], 2.9; 95% CI, 1.5 to 5.3), poverty (OR, 4.2; 95% CI, 1.9 to 9.1), and daily consumption of processed meat (OR, 6.4; 95% CI, 1.3 to 32) and negatively associated with consumption of green vegetables (OR, 0.2; 95% CI, 0.1 to 0.5). Gastric cancer was also associated with biomass smoke exposure (OR, 3.5; 95% CI, 1.9 to 6.2; P less then .0001), an association that was stronger for intestinal-type cancers (OR, 3.6; 95% CI, 1.5 to 9.1; P = .003). Exposure to biomass smoke in controls was associated with higher urinary levels of 8-isoprostane (P less then .0001), 8-hydroxydeoxyguanosine (P = .029), and 1-hydroxypyrene (P = .041). Gastric cancer was not associated with biochemical measures of current exposure to aflatoxins or ochratoxins. CONCLUSION In Zambia, exposure to biomass smoke, daily consumption of processed meat, and poverty are risk factors for gastric cancer, whereas daily consumption of green vegetables is protective against gastric cancer. Exposure to biomass smoke was associated with evidence of oxidative stress and DNA damage, suggesting mechanistic plausibility for the observed association, and the association was restricted to intestinal-type gastric cancer.Importance Social media has become a mainstream method of allowing patients to report and rate their satisfaction with cosmetic procedures and providers. To date, very few studies have published patient-reported satisfaction with the rhytidectomy procedure. Objective We sought to perform a social media analysis of the rhytidectomy procedure. Design, Setting, and Participants Data were extracted from 1876 consecutive rhytidectomy online reviews completed by individuals on "facelift" from the RealSelf website, from April 2017 to June 2019. Patients who did not undergo the procedure were excluded. Main Outcomes and Measures Reasons for pursuing surgery, choosing a surgeon, and liking the surgical outcome were identified. Surgical and demographic variables, cost, and overall "Worth It" scores were recorded. Data were analyzed using SPSS Version 25. Valid frequencies and percentages are presented excluding missing data. Results Of the data that could be extracted from 1876 RealSelf reviews, the majority of reviewelevance The overall satisfaction with rhytidectomy surgery was high within this cohort, which is in keeping with satisfaction rates reported in the literature. Many patients chose their surgeon based on favorable personality traits and emotional connections rather than other factors.Importance Hematoma is the most common complication in rhytidectomy. Tranexamic acid (TXA) is an antifibrinolytic that may be a useful tool to reduce intraoperative bleeding and postoperative hematoma risk. Objective To determine whether local TXA reduces intraoperative bleeding and postoperative drain output in rhytidectomy. Design, Setting, and Participants Retrospective cohort study of patients undergoing deep plane rhytidectomy with platysmaplasty. Beginning January 1, 2019, we began adding 1 cc (100 mg) of TXA to every 10 cc of local anesthetic and tumescent solution. Patients were, therefore, separated into two cohorts control and TXA. Primary outcomes include postoperative day 1 (POD1) drain output, days to drain removal, percentage drains removed POD1, and percentage POD1 drain output less then 25 cc. Secondary outcomes include minor hematoma, major hematoma, Nitro-bid use, intraoperative estimated blood loss (EBL), and thromboembolic events. Results POD1 drain output reduced from 50.4 cc in control group versus 14.8 cc with TXA (p  less then  0.001). Average day of drain removal reduced from 1.8 days in control group versus 1.2 days with TXA (p = 0.001). Percentage of drains removed on POD1 was increased from 34.4% in control group to 77.3% with TXA (p  less then  0.001). Percentage of POD1 drain output less then 25 cc was increased from 21.9% in control group to 95.5% with TXA (p  less then  0.001). Intraoperative EBL less then 50 cc increased from 25% in control group to 75% with TXA (p  less then  0.001). Caspase cleavage No statistically significant difference was observed between control and TXA in rates of minor hematoma, major hematoma, Nitro-bid use, or thromboembolic events. Conclusions and Relevance Local TXA used in rhytidectomy significantly reduces intraoperative blood loss, postoperative drain output, and time to drain removal. No significant difference was observed in postoperative complication rates.Despite the development of new oral agents over the last decade, vitamin K antagonists (VKAs) remain the most widely used anticoagulants for treating and preventing thromboembolism worldwide. In Chile, the Ministry of Health indicates that acenocoumarol should be used in preference to any other coumarin. Complications of inappropriate dosing are among the most frequently reported adverse events associated with this medication. It is well known that polymorphisms in pharmacokinetic and pharmacodynamic proteins related to coumarins (especially warfarin) influence response to these drugs. This work analyzed the impact of CYP2C19*2 (rs4244285), CYP1A2*1F (rs762551), GGCx (rs11676382), CYP2C9*2 (rs1799853), CYP2C9*3 (rs1057910), CYP4F2 (rs2108622), VKORC1 (rs9923231), VKORC1 (rs7294), CYP3A4*1B (rs2740574), and ABCB1 (rs1045642) polymorphisms on time to therapeutic range for oral anticoagulants in 304 Chilean patients. CYP2C9*3 polymorphisms were associated with time to therapeutic range for acenocoumarol in Chilean patients, and the CYP4F2 TT genotype, MDR1 A allele, CYP1A2 A allele, and CYP3A4T allele are promising variants that merit further analysis.
