A 12-month follow-up of a mobile-based (mHealth) obesity prevention intervention in pre-school children: the MINISTOP randomized controlled trial
Background: To date, few mobile health (mHealth) interventions aimed at changing lifestyle behaviors have
measured long term effectiveness. At the 6-month follow-up the MINISTOP trial found a statistically significant
intervention effect for a composite score comprised of fat mass index (FMI) as well as dietary and physical activity
variables; however, no intervention effect was observed for FMI. Therefore, the aim of this study was to investigate
if the MINISTOP intervention 12-months after baseline measurements: (i) improved FMI and (ii) had a maintained
effect on a composite score comprised of FMI and dietary and physical activity variables.
Methods: A two-arm parallel randomized controlled trial was conducted in 315 healthy 4.5 year old children
between January 2014 and October 2015. Parents’ of the participating children either received the MINISTOP
intervention or a basic pamphlet on dietary and physical activity behaviors (control group). After 6 months,
participants did not have access to the intervention content and were measured again 6 months later (i.e. the
12-month follow-up). The Wilcoxon rank-sum test was then used to examine differences between the groups.
Results: At the 12-month follow-up, no statistically significant difference was observed between the intervention
and control groups for FMI (p = 0.57) and no maintained effect for the change in composite score was observed
(mean ± standard deviation for the intervention and control group: + 0.53 ± 1.49 units and + 0.35 ± 1.27 units
respectively, p = 0.25 between groups).
Conclusions: The intervention effect observed at the 6-month follow-up on the composite score was not
maintained at the 12-month follow-up, with no effect on FMI being observed at either follow-up. Future studies
using mHealth are needed to investigate how changes in obesity related markers in young children can be
maintained over longer time periods.The MINISTOP project was funded by the Swedish Research Council (project

Loss of Function of TET2 Cooperates with Constitutively Active KIT in Murine and Human Models of Mastocytosis
Systemic Mastocytosis (SM) is a clonal disease characterized by abnormal accumulation of mast cells in multiple organs. Clinical presentations of the disease vary widely from indolent to aggressive forms, and to the exceedingly rare mast cell leukemia. Current treatment of aggressive SM and mast cell leukemia is unsatisfactory. An imatinib-resistant activating mutation of the receptor tyrosine kinase KIT (KIT D816V) is most frequently present in transformed mast cells and is associated with all clinical forms of the disease. Thus the etiology of the variable clinical aggressiveness of abnormal mast cells in SM is unclear. TET2 appears to be mutated in primary human samples in aggressive types of SM, suggesting a possible role in disease modification. In this report, we demonstrate the cooperation between KIT D816V and loss of function of TET2 in mast cell transformation and demonstrate a more aggressive phenotype in a murine model of SM when both mutations are present in progenitor cells. We exploit these findings to validate a combination treatment strategy targeting the epigenetic deregulation caused by loss of TET2 and the constitutively active KIT receptor for the treatment of patients with aggressive SM
Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy
Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe
Global variation in anastomosis and end colostomy formation following left-sided colorectal resection
Background
End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection.
Methods
This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model.
Results
In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001).
Conclusion
Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone
EPIDEMIOLOGICAL CHARACTERISTICS OF GERIATRIC PATIENTS IN EMERGENCY
Introduction: The increasing proportion of elderly individuals in the population due to increased life expectancy has necessitated greater provision of health care. Here we aimed to determine patient characteristics, reasons for referral, and outcomes of emergency department visits and hospitalization in patients aged ? 65 years with referrals to emergency departments.Materials and Method: This prospective, multicenter observational study was conducted over one week at the emergency departments of 13 Turkey hospitals. All patients aged ? 65 years who were referred to emergency departments with acute medical or surgical issues during the study period were included. Patients aged <65 years or those referred for trauma were excluded.Results: In total, 1299 patients with a mean age of 74.8 +/- 7.3 years were included. Of these, 51.9% (n=674) were aged 65-74 years, 67.5% (n=877) were discharged from the hospital, and 5.8% (n=75) died during admission. The most frequently diagnosed disorders in the emergency departments were cardiovascular, gastrointestinal, and pulmonary diseases. A significant difference in age was observed between the survival and non-survival groups (p=0.001), with no significant differences in gender distribution (p=0.259), length of stay in intensive care units (p=0.605), or length of stay in hospital (p=0.055).Conclusion: With an increased proportion of elderly individuals in the general population, the number of elderly patients referred to emergency departments continues to increase. This study presents the demographic features and clinical course of elderly patients referred to study centers
