Abstract
The aim of this study was to determine the superiority between the robotic da Vinci Si® (Si group) and da Vinci Xi® (Xi group) generation in patients with mid-low rectal cancer. Between December 2011 and December 2017, 88 patients with mid-low rectal cancer were operated on using the Si robotic system, from January 2018 to May 2021, 62 more patients with mid-low rectal cancer were operated on using the Xi robotic system. Perioperative and postoperative short-term outcomes were compared between the two groups. Univariate and multivariate Cox-regression analysis were performed to determine factors affecting operating time. A cumulative sum (CUSUM) analysis was also performed to determine the learning curve of the primary surgeon. All patients underwent sphincter saving total mesorectal excision (TME). The overall operating time was significantly shorter in the Xi group (181.3 ± 31.8 min in Si group vs 123.6 ± 25.7 min in the Xi group, p < 0.001). There were no significant differences in terms of conversion rates, mean hospital stays, complications and histopathologic data. CUSUM analysis show completion of learning curve in 44th case of Si group. Univariate and multivariate analysis demonstrated that the learning curve of the primary surgeon (p < 0.001) and the type of robotic system (Xi) are only two factors associated with operating time (OR, 95% CI p; 3.656, 0.665-9.339, p < 0.001). Our study found that the robotic da Vinci Xi systems provide significantly shorter operating time comparing with Si systems, when performing sphincter-preserving TME in mid-low rectal cancer patients. Surgical system (da Vinci Xi) and primary surgeon learning curve are two independent risk factors which associated shortened operating time. Postoperative complication rates and histopathologic outcomes are similar in both groups.

Effect on mortality of increasing the cutoff blood glucose concentration for initiating hypoglycaemia treatment in severely sick children aged 1 month to 5 years in Malawi (SugarFACT): a pragmatic, randomised controlled trial. LANCET GLOBAL HEALTH 2020; 8:e1546-e1554. [PMID: 33038950 DOI: 10.1016/s2214-109x(20)30388-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 07/03/2020] [Accepted: 08/14/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Low blood glucose concentrations are common in sick children who present to hospital in low-resource settings and are associated with increased mortality. The cutoff blood glucose concentration for the diagnosis and treatment of hypoglycaemia currently recommended by WHO (2·5 mmol/L) is not evidence-based. We aimed to assess whether increasing the cutoff blood glucose concentration for hypoglycaemia treatment in severely ill children at presentation to hospital improves mortality outcomes. METHODS We did a pragmatic, randomised controlled trial at two referral hospitals in Malawi. Severely ill children aged 1 month to 5 years presenting to the emergency department with a capillary blood glucose concentration of between 2·5 mmol/L (3·0 mmol/L in severely malnourished children) and 5·0 mmol/L were randomly assigned (1:1) by a computer-generated randomisation sequence, stratified by study site and severe malnutrition, to receive either an immediate intravenous bolus of 10% dextrose at 5 mL/kg followed by a 24-h maintenance infusion of 10% dextrose at 100 mL/kg for the first 10 kg of bodyweight, 50 mL/kg for the next 10 kg, and 20 mL/kg for each subsequent kg of bodyweight (intervention group) or observation for a minimum of 60 min and standard care (control group). Participants and study personnel were not masked to treatment allocation. The primary outcome was all-cause in-hospital mortality, assessed on an intention-to-treat basis. Safety was also assessed in the intention-to-treat population. The study is registered with ClinicalTrials.gov, NCT02989675. FINDINGS Between Dec 5, 2016, and Jan 22, 2019, 10 947 children were screened, of whom 332 were randomly assigned, and 322 were included in the final analysis (n=162 in the control group and n=160 in the intervention group). The study was terminated after an interim analysis at 24% enrolment indicated futility. The median age of participants was 2·3 years (IQR 1·4-3·2), 65 (45%) were female, and the baseline characteristics of participants were similar between the two groups. The number of in-hospital deaths from any cause was 26 (16%) in the control group and 24 (15%) in the intervention group, with an absolute mortality difference of 1·0% (95% CI -6·9 to 9·0). Serious adverse events, including hypoglycaemia, hyperglycaemia, convulsions, reduced consciousness, and death, were reported in 47 (29%) children in the control group and 39 (24%) children in the intervention group. INTERPRETATION Increasing the cutoff blood glucose concentration for hypoglycaemia treatment in severely sick children in Malawi from 2·5 mmol/L to 5·0 mmol/L did not reduce all-cause in-hospital mortality. Our findings do not support changing the cutoff for dextrose administration, and further research on the optimal management of severely ill children who present to the emergency department with low blood glucose concentrations is warranted.

Abstract
In low-resource settings, many children are severely ill at arrival to hospital. The risk factors for mortality among such ill children are not well-known. Understanding which of these patients are at the highest risk could assist in the allocation of limited resources to where they are most needed. A cohort study of severely ill children treated in the resuscitation room of the pediatric emergency department at Queen Elizabeth Central Hospital in Malawi was conducted over a 6-month period in 2017. Data on signs and symptoms, vital signs, blood glucose levels, and nutritional status were collected and linked with in-hospital mortality data. The factors associated with in-hospital mortality were analyzed using multivariable logistic regression. Data for 1,359 patients were analyzed and 118 (8.7%) patients died. The following factors were associated with mortality: presence of any severely deranged vital sign, unadjusted odds ratio (UOR) 2.6 (95% CI 1.7–4.0) and adjusted odds ratio (AOR) 3.2 (95% CI 2.0–5.0); severe dehydration, UOR 2.6 (1.4–5.1) and AOR 2.8 (1.3–6.0); hypoglycemia glycemia (< 5 mmol/L), UOR 3.6 (2.2–5.8) and AOR 2.7 (1.6–4.7); and severe acute malnutrition, UOR 5.8 (3.5–9.6) and AOR 5.7 (3.3–10.0). This study suggests that among severely sick children, increased attention should be given to those with hypo/low glycemia, deranged vital signs, malnutrition, and severe dehydration to avert mortality among these high-risk patients.

Abstract
Background: Acutely sick children in resource-constrained settings who present with hypoglycaemia have poor outcomes. Studies have questioned the current hypoglycaemia treatment cut-off level of 2.5 mmol/l. Improved knowledge about health workers’ attitudes towards and management of hypoglycaemia is needed to understand the potential effects of a raised cut-off level. Objective: This research explored health workers’ perceptions about managing acutely ill children with hypoglycaemia in a Malawian referral hospital. A secondary objective was to explore health workers’ opinions about a potential increase in the hypoglycaemia cut-off level. Methods: We used a qualitative design with semi-structured individual interviews performed with health workers in the Paediatric Accident and Emergency Unit at Queen Elizabeth Central Hospital, Malawi, in October 2016. Data were analysed using latent content analysis. Ethical approval was obtained from the University of Malawi, College of Medicine Research and Ethics Committee P.01/16/1852. Results: Four themes were formed that described the responses. The first, ‘Critical and difficult cases need easy treatment’, showed that health workers perceived hypoglycaemia as a severe condition that was easily manageable. The second, ‘Health system issues’, revealed challenges relating to staffing and resource availability. The third, ‘From parental reluctance to demand’, described a change in parents’ attitudes regarding intravenous treatments. The fourth, ‘Positive about the change but need more information’, exposed health workers’ concerns about potential risks of a raised cut-off level for hypoglycaemia treatment, as well as benefits for the patients. Conclusions: Health workers perceived hypoglycaemia as a severe condition that is easy to manage when the required equipment and supplies are available. Due to the common lack of test equipment and dextrose supplies, health workers have adopted alternative strategies to diagnose and manage hypoglycaemia. A change to the hypoglycaemia treatment cut-off level raised concerns about potential risks, but was also thought to be of benefit for some patients.
