[Prevalence and Trends in Prepregnancy Overweight and Obesity in Northern Iceland 2004-2022].

INTRODUCTION: Prepregnancy overweight and obesity is an increasing public health issue worldwide, including Iceland, and has been associated with higher risk of adverse maternal and birth outcomes. The aim of this study was to investigate trends in prepregnancy weight amongst women in North Iceland from 2004 to 2022, and the prevalence of overweight and obesity in this population. MATERIAL AND METHODS: This retrospective cross-sectional study included all women who gave birth at Akureyri Hospital in North Iceland between 2004 and 2022 (N = 7410). Information on age, parity, height, and prepregnancy weight was obtained from an electronic labour audit database. Body mass index (BMI) was calculated from self-reported height and weight, and the median BMI and proportions in each of the six BMI categories were calculated for four time periods. RESULTS: Median BMI increased significantly from 24.5 kg/m2 in 2004-2008 to 26.2 kg/m2 in 2019-2022. On average, BMI increased by 0.15 kg/m2 with each passing year (p<0.001). The prevalence of normal weight decreased from 53% to 40% and the entire BMI distribution shifted towards a higher BMI. The proportion of women in obesity class I (BMI 30.0 - 34.9) increased from 12.8% to 17.3%, the proportion of women in obesity class II (BMI 35.0 - 39.9) doubled (3.7% to 8.1%) and tripled in obesity class III (BMI ≥ 40.0; 1.6% to 4.8%). CONCLUSION: Prepregnancy weight of women in Northern Iceland has gradually increased over the last 19 years and 30% of pregnant women are now classified as obese. Further studies on the subsequent effects on maternal and birth outcomes are needed, with a focus on strategies to decrease adverse effects and reverse this trend.

Locating helicopter ambulance bases in Iceland: efficient and fair solutions.

BACKGROUND: Fixed-wing air ambulances play an important role in healthcare in rural Iceland. More frequent use of helicopter ambulances has been suggested to shorten response times and increase equity in access to advanced emergency care. In finding optimal base locations, the objective is often efficiency-maximizing the number of individuals who can be reached within a given time. This approach benefits people in densely populated areas more than people living in remote areas and the solution is not necessarily fair. This study aimed to find efficient and fair helicopter ambulance base locations in Iceland. METHODS: We used high-resolution population and incident location data to estimate the service demand for helicopter ambulances, with possible base locations limited to twenty-one airports and landing strips around the country. Base locations were estimated using both the maximal covering location problem (MCLP) optimization model, which aimed for maximal coverage of demand, and the fringe sensitive location problem (FSLP) model, which also considered uncovered demand (i.e., beyond the response time threshold). We explored the percentage of the population and incidents covered by one to three helicopter bases within 45-, 60-, and 75-min response time thresholds, conditioned or not, on the single existing base located at Reykjavík Airport. This resulted in a total of eighteen combinations of conditions for each model. The models were implemented in R and solved using Gurobi. RESULTS: Model solutions for base locations differed between the demand datasets for two out of eighteen combinations, both with the lowest service standard. Base locations differed between the MCLP and FSLP models for one combination involving a single base, and for two combinations involving two bases. Three bases covered all or almost all demand with longer response time thresholds, and the models differed in four of six combinations. The two helicopter ambulance bases can possibly obtain 97% coverage within 60 min, with bases in Húsafell and Grímsstaðir. Bases at Reykjavík Airport and Akureyri would cover 94.2%, whereas bases at Reykjavík Airport and Egilsstaðir would cover 88.5% of demand. CONCLUSION: An efficient and fair solution would be to locate bases at Reykjavík Airport and in Akureyri or Egilsstaðir.

Understanding exercise addiction, psychiatric characteristics and use of anabolic androgenic steroids among recreational athletes - An online survey study.

Background: The purpose of this paper was to explore maladaptive behaviors among physically active individuals, including exercise dependence and use of anabolic steroids. Both exercise addiction (EA) and use of anabolic androgenic steroids (AAS) correlate to high amounts of exercise and EA have been linked to eating disorders and other mental health problems. Methods: An internet survey was spread through fitness-related social media. Inclusion criteria were age ≥ 15 years and exercise frequency ≥ thrice weekly. Exercise addiction inventory identified those at-risk of EA (rEA). Characteristics of rEA were compared to those not at risk. In a separate analysis, AAS users were compared to AAS-naïve individuals. Results: In total, 3,029 participants completed the questionnaire. Of these, 11% screened positive for being rEA, and 23% for ED. Factors associated with EA included daily exercise, social phobia, eating disorders and OCD. Risk consumption of alcohol was a negative predictor. Thirty seven participants had taken AAS the last year. These were mainly men, bodybuilders/powerlifters and more often used amphetamines and opioids. Discussion: This exploratory study supports EA being strongly associated with eating disorders. Identified associations between EA and compulsive or anxiety disorders warrant further research to clarify if these associations arise prior to, together with, or secondary to EA.

[Air ambulance service from Akureyri, Iceland 2012-2020].

INTRODUCTION: This study investigated the use of fixed-wing air ambulance in Iceland between 2012 and 2020. MATERIAL: Medical records were filled out during each flight and information afterwards entered into an electronic database. METHODS: The annual number of patient transports nationwide; triage scale category; reason for transportation, age and gender; and departure and arrival airports were analyzed. Response time and total transport time were compared between years and locations. Poisson regression analysis was used to compare the yearly number of transports. One-way ANOVA was used to compare response time and total transport time by year and departure site. RESULTS: In total, 6011 patients were transported in fixed-wing air ambulances during the study period. Majority were male (54.3%). Median age was 64 years (range 0-99 years). Most patients were transported due to medical conditions; 15.8% due to trauma. Thirty percent of women aged 20 to 44 years were transported due to pregnancy or childbirth. Two-thirds of patients were transported to Reykjavik (n=3937), and one-fifth to Akureyri (n=1139). Median response time for acute transports was 84 minutes (range 0-2870 minutes). Median total transport time was 150 minutes (range 50-2930 minutes). Differences were found in total transport time from departure locations (F=32.19; DF 9, 2678; p<0,001). Egilsstaðir, Norðfjörður, Höfn, and, partly, Ísafjörður had the longest total transport times. CONCLUSION: Icelandic air ambulance flights are often long, likely affecting outcomes for patients with time-sensitive medical conditions. Access to specialized healthcare is unequal among places of residence, and it is important to address this.

Patient handover between ambulance crew and healthcare professionals in Icelandic emergency departments: a qualitative study.

BACKGROUND: Ambulance services play an important role in the healthcare system when it comes to handling accidents or acute illnesses outside of hospitals. At the time of patient handover from emergency medical technicians (EMTs) to the nurses and physicians in emergency departments (EDs), there is a risk that important information will be lost, the consequences of which may adversely affect patient well-being. The study aimed to describe healthcare professionals' experience of patient handovers between ambulance and ED staff and to identify factors that can affect patient handover quality. METHODS: The Vancouver School's phenomenological method was used. The participants were selected using purposive sampling from a group of Icelandic EMTs, nurses, and physicians who had experience in patient handovers. Semi-structured individual interviews were conducted and were supported by an interview guide. The participants included 17 EMTs, nurses, and physicians. The process of patient handover was described from the participants' perspectives, including examples of communication breakdown and best practices. RESULTS: Four main themes and nine subthemes were identified. In the theme of leadership, the participants expressed that it was unclear who was responsible for the patient and when during the process the responsibility was transferred between healthcare professionals. The theme of structured framework described the communication between healthcare professionals before patient's arrival at the ED, upon ED arrival, and a written patient report. The professional competencies theme covered the participants' descriptions of professional competences in relation to education and training and attitudes towards other healthcare professions and patients. The collaboration theme included the importance of effective teamwork and positive learning environment. CONCLUSIONS: A lack of structured communication procedures and ambiguity about patient responsibility in patient handovers from EMTs to ED healthcare professionals may compromise patient safety. Promoting accountability, mitigating the diffusion of responsibility, and implementing uniform practices may improve patient handover practices and establish a culture of integrated patient-centered care.

Problem Gambling in the Fitness World-A General Population Web Survey.

The world of sports has a complex association to problem gambling, and the sparse research examining problem gambling in athletes has suggested an increased prevalence and particularly high male predominance. The present study aimed to study frequency and correlates of problem gambling in populations with moderate to high involvement in fitness or physical exercise. This is a self-selective online survey focusing on addictive behaviors in physical exercise distributed by 'fitness influencers' on social media and other online fitness forums to their followers. Respondents were included if they reported exercise at least thrice weekly, were above 15 years of age, and provided informed consent (N = 3088). Problem gambling, measured with the Lie/Bet, was studied in association with demographic data, substance use, and mental health variables. The occurrence of lifetime problem gambling was 8 percent (12 percent in men, one percent in women). In logistic regression, problem gambling was associated with male gender, younger age, risky alcohol drinking, obsessive-compulsive disorder, and less frequent exercise habits. In conclusion, in this self-recruited population with moderate to high fitness involvement, problem gambling was moderately elevated. As shown previously in elite athletes, the male predominance was larger than in the general population. The findings strengthen the link between problem gambling and the world of sports.

On predicting time to completion for the first stage of spontaneous labor at term in multiparous women.

BACKGROUND: Labor that progresses faster than anticipated may lead to unplanned out-of-hospital births. With the aim to improve planning of transportation to birthing institutions, this study investigated predictors of time to completion for the first stage of labor conditional on cervical opening (conditional time) in multiparous women at term. METHODS: We performed a retrospective analysis of partograms for women in Robson's group 3 who delivered at one hospital from 2003 to 2013. A generalized additive mixed model was fitted, accounting for possible non-linear relationships between the predictor variables and outcome, e.g. the time from each cervical measurement to full dilation, using multiple measurements for each woman. The following predictors were included: cervical dilation (cm), parity (1, 2, or ≥3 previous vaginal births), oxytocin infusion (no/yes), epidural (no/yes), maternal age (years), maternal height (cm), body mass index (BMI, kg/m2), birthweight (kg), spontaneous rupture of membranes (no/yes). A modified regression model with gestational age (days) instead of birthweight was used to predict conditional time to full cervical dilation for combinations of the most relevant predictors. RESULTS: A total of 1753 partograms were included in the analysis. The strongest predictors were birthweight, epidural and oxytocin use, and spontaneous rupture of membranes, along with cervical measurements. For birthweight, there was an almost 40% increase in time to full cervical dilation for each 1-kg increment. Conditional time was on average 23% longer in cases with epidural use and 53% longer in cases requiring oxytocin augmentation. Spontaneous rupture of the membranes shortened conditional time by 31%. Maternal age was not associated with the outcome, while increasing BMI and parity modestly reduced conditional time. CONCLUSIONS: Higher parity, lower fetal weight (gestational age), and spontaneous rupture of the membranes are associated with more rapid labor.

Why babies die in unplanned out-of-institution births: an enquiry into perinatal deaths in Norway 1999-2013.

INTRODUCTION: The aims were to describe causes of death associated with unplanned out-of-institution births, and to study whether they could be prevented. MATERIAL AND METHODS: Retrospective population-based observational study based on data from the Medical Birth Registry of Norway and medical records. Between 1 January 1999 and 31 December 2013, 69 perinatal deaths among 6027 unplanned out-of-institution births, whether unplanned at home, during transportation, or unspecified, were selected for enquiry. Hospital records were investigated and cases classified according to Causes of Death and Associated Conditions. RESULTS: 63 cases were reviewed. There were 25 (40%) antepartum deaths, 10 (16%) intrapartum deaths, and 24 neonatal (38%) deaths. Four cases were in the unknown death category (6%). Both gestational age and birthweight followed a bimodal distribution with modes at 24 and 38 weeks and 750 and 3400 g, respectively. The most common main cause of death was infection (n = 14, 22%), neonatal (n = 14, 22%, nine due to extreme prematurity) and placental (n = 12, 19%, seven placental abruptions). There were 86 associated conditions, most commonly perinatal (n = 32), placental (n = 15) and maternal (n = 14). Further classification revealed that the largest subgroup was associated perinatal conditions/sub-optimal care, involving 25 cases (40%), most commonly due to sub-optimal maternal use of available care (n = 14, 22%). CONCLUSIONS: Infections, neonatal, and placental causes accounted for almost two-thirds of perinatal mortality associated with unplanned out-of-institution births in Norway. Sub-optimal maternal use of available care was found in more than one-fifth of cases.

Reporting Helicopter Emergency Medical Services in Major Incidents: A Delphi Study.

OBJECTIVE: Research on helicopter emergency medical services (HEMS) in major incidents is predominately based on case descriptions reported in a heterogeneous fashion. Uniform data reported with a consensus-based template could facilitate the collection, analysis, and exchange of experiences. This type of database presently exists for major incident reporting at www.majorincidentreporting.net. This study aimed to develop a HEMS-specific major incident template. METHODS: This Delphi study included 17 prehospital critical care physicians with current or previous HEMS experience. All participants interacted through e-mail. We asked these experts to define data variables and rank which were most important to report during an immediate prehospital medical response to a major incident. Five rounds were conducted. RESULTS: In the first round, the experts suggested 98 variables. After 5 rounds, 21 variables were determined by consensus. These variables were formatted in a template with 4 main categories: HEMS background information, the major incident characteristics relevant to HEMS, the HEMS response to the major incident, and the key lessons learned. CONCLUSION: Based on opinions from European experts, we established a consensus-based template for reporting on HEMS responses to major incidents. This template will facilitate uniformity in the collection, analysis, and exchange of experience.

Air ambulance and hospital services for critically ill and injured in Greenland, Iceland and the Faroe Islands: how can we improve?

The Nordic Atlantic Cooperation (NORA) is an intergovernmental organization under the auspices of the Nordic Council of Ministers. The NORA region comprises Greenland, Iceland, Faroe Islands and western coastal areas of Norway. Historical, cultural and institutional links bind these nations together in multiple ways, and regional co-operation has in recent years become a focus of interest. This commentary addresses air medical services (AMSs) and available advanced hospital services in the 3 smallest NORA countries challenged sparse populations, hereafter referred to as the region. It seems likely that strengthened regional co-operation can help these countries to address common challenges within health care by exchanging know-how and best practices, pooling resources and improving the efficiency of care delivery. The 4 largest hospitals in the region, Dronning Ingrids Hospital in Nuuk (Greenland), Landspítali in Reykjavík and Sjúkrahúsið á Akureyri, (both in Iceland) and Landssjúkrahúsið Tórshavn on the Faroe Islands, have therefore undertaken the project Network for patient transport in the North-West Atlantic (in Danish: Netværk for patienttransport i Vest-Norden). The goal of the project, and of this article, is to exchange information and provide an overview of current AMSs and access to acute hospital care for severely ill or injured patients in the 3 participating countries. Of equal importance is the intention to highlight the need for increased regional co-operation to optimize use of limited resources in the provision of health care services.

Characteristics and outcome of unplanned out-of-institution births in Norway from 1999 to 2013: a cross-sectional study.

OBJECTIVE: To study the incidence, maternal characteristics and outcome of unplanned out-of-institution births (= unplanned births) in Norway. DESIGN: Register-based cross-sectional study. POPULATION: All births in Norway (n = 892 137) from 1999 to 2013 with gestational age ≥22 weeks. METHODS: Analysis of data from the Medical Birth Registry of Norway from 1999 to 2013. Unplanned births (n = 6062) were compared with all other births (reference group). RESULTS: The annual incidence rate of unplanned births was 6.8/1000 births and remained stable during the period of study. Young multiparous women residing in remote municipalities were at the highest risk of experiencing unplanned births. The unplanned birth group had higher perinatal mortality rate for the period, 11.4/1000 compared with 4.9/1000 for the reference group (incidence rate ratio 2.31, 95% confidence interval 1.82-2.93, p < 0.001). Annual perinatal mortality rate for unplanned births did not change significantly (p = 0.80) but declined on average by 3% per year in the reference group (p < 0.001). The unplanned birth group had a lower proportion of live births in all birthweight categories. Live born neonates with a birthweight of 750-999 g in the unplanned birth group had a more than five times higher mortality rate during the first week of life, compared with reference births in the same birthweight category. CONCLUSIONS: Unplanned births are associated with adverse outcome. Excessive mortality is possibly caused by reduced availability of necessary medical interventions for vulnerable newborns out-of-hospital.

[Management of patients with STEMI transported with air-ambulance to Landspitali University Hospital in Reykjavík]. / Flutningstími og gaedi medferdar hjá sjúklingum med ST-haekkunar hjartadrep á Nordur- og Austurlandi.

INTRODUCTION: A good outcome of patients presenting with STEMI (ST-Segment Elevation Myocardial Infarction) depends on early restoration of coronary blood flow. Pre-hospital fibrinolysis is recommended if primary percutaneous coronary intervention (PPCI) cannot be performed within 90 minutes of first medical contact (FMC). The purpose of this study was to study transport times for patients with STEMI who were transported with air-ambulance from the northern rural areas of Iceland to Landspitali University Hospital in Reykjavík, and to assess if the medical management was in accordance with clinical guidelines. MATERIALS AND METHODS: Retrospective chart review identified 33 patients with STEMI who were transported with air-ambulance to Landspitali University Hospital in Reykjavík during the years 2007 and 2008. RESULTS: The total time from first medical contact to arrival at Landspitali University Hospital emergency room was 3 hours and 7 minutes (median). All patients received aspirin and 26 (78.8%) received clopidogrel and enoxaparin. 16 patients (48.5%) received thrombolytic therapy in median 33 minutes after FMC and 15 patients had PPCI performed in median 4 hours and 15 minutes after FMC. Estimated PCI related delay was 3 hours and 42 minutes (median). One patient died and one was resuscitated within 30 hospital days. Mean hospital stay was 6.0 days. CONCLUSIONS: First medical contact to balloon time of less than 90 minutes is impossible for patients with STEMI transported from the northern rural areas to Landspitali University Hospital in Reykjavík. Medical therapy was in many cases suboptimal and PCI related delay too long.

Dietary quality and adequacy of micronutrient intakes in children.

Presented are longitudinal studies, extending from infancy (n 180) to 2 years of age (n 130) and 6 years of age (>70% participation) of diet and Fe status in a population with high birth weight, high frequency of breast-feeding and, at the time of the study, high intake of cow's milk during the weaning period. The association between socio-demographic and dietary factors was also studied, together with Fe status in early childhood and developmental status at 6 years. Fe status was found to be poorer than in the neighbouring Nordic countries. Every fifth 1-year-old was Fe-deficient (serum ferritin <12 microg/l and mean corpuscular volume <74 fl). It was demonstrated by regression analysis that Fe status was negatively associated with cow's milk consumption at 9-12 months (significant at >460 g/d) and was weakly positively associated with fish, meat and Fe-fortified cereal consumption. Fe-deficient infants had a shorter duration of breast-feeding, and breast-feeding was related to slower growth, which can protect from worsening Fe status. Fe deficiency was less common at ages 2 and 6 years. Maternal factors associated with lower adherence to the recommended infant diet were less education, lower age and smoking. In a multiple stepwise regression analysis that included food factors, socio-demographic factors were not found to be associated with Fe status. Fe-depleted and Fe-deficient 1-year-olds had lower fine motor scores when they were 6 years old than those who were not Fe-deficient or Fe-depleted. The findings of these studies have already led to changes in the local recommendations for diet in infancy. The results suggest that Fe deficiency at 12 months of age affects development at 6 years of age. The studies indicated that mothers with less education, who smoked and who were younger needed more guidance concerning recommendations about diet in infancy.

Effects of sociodemographic factors on adherence to breastfeeding and other important infant dietary recommendations.

AIM: To examine in an affluent and healthy population the association between sociodemographic factors and the adherence to key infant dietary recommendations. METHODS: In a longitudinal prospective study, healthy newborns were selected randomly in maternity wards around Iceland and their diet recorded every month for one year (n = 124). In addition, a 48-hour-weighed-record, including information on added sugar, fruits, vegetables and the use of A and D vitamin drops was completed by 91 (73%) mothers at 9 and 12 months. Information about the mothers' education, smoking, age, parity, and family income was collected (n = 98; 79%). RESULTS: Regression analyses, including sociodemographic factors, showed exclusive breastfeeding to be positively associated with more education (P = 0.022) and non-smoking (P = 0.013) explaining 22% of the variance, and total breastfeeding (exclusive + partial) with non-smoking (P = 0.006). Multiple regression also showed children's intake of added sugar from 9-12 months to be positively associated with mother's smoking (P = 0.022) and negatively with age (P = 0.026), explaining 30% of variance. Sociodemographic factors were associated with children's fruit and vegetable consumption but not with the administration of AD-vitamin drops. However, when tested for significance between groups, younger mothers with fewer children seemed less likely to give AD-vitamin drops. CONCLUSIONS: In a group of mothers getting regular antenatal care and giving birth to healthy infants, sociodemographic factors can predict which mothers need special guidance concerning recommendations about diet in infancy. These were mothers with less education, who smoked, were younger and were having their first or second child.

Perfluorooctyl bromide (perflubron) attenuates oxidative injury to biological and nonbiological systems.

OBJECTIVE: To examine whether perfluorooctyl bromide (perflubron) is capable of protecting biological and nonbiological systems against oxidative damage through a mechanism independent of its known anti-inflammatory property. DESIGN: A controlled, in vitro laboratory study. SETTING: Research laboratory of a health sciences university. SUBJECTS: Rat pulmonary artery endothelial cell cultures (biological system) and linoleic acid in sodium dodecyl sulfate micelles (nonbiological system). INTERVENTIONS: Rat pulmonary artery endothelial cells labeled with dichlorofluorescein diacetate and incubated with perflubron or culture media (control) were exposed to H2O2. H2O2-induced fluorescence of dichlorofluorescein diacetate was measured as an index of intracellular oxidative stress. In another experiment, linoleic acid in sodium dodecyl sulfate micelles was exposed to various concentrations of the azo initiator 2,2'-diazo-bis-(2-amidinopropane) dihydrochloride (2, 4, 20, and 50 mM) in the presence or absence of perflubron. Malondialdehyde measurements were obtained as a marker of oxidative damage to linoleic acid. MEASUREMENTS AND MAIN RESULTS: Cell monolayers incubated with perflubron exhibited 66.6% attenuation in intracellular fluorescence compared with controls (p < .05). Linoleic acid in sodium dodecyl sulfate micelles incubated with perflubron and exposed to 2, 4, 20, or 50 mM of 2,2'-diazo-bis-(2-amidinopropane) dihydrochloride showed less evidence of lipid peroxidation as indicated by lower malondialdehyde measurements at 240 mins (10.6%, 16%, 41%, and 14.2%, respectively) compared with controls. CONCLUSIONS: Perflubron attenuates oxidative damage to both biological and nonbiological systems. This newly recognized property of perflubron is independent of its anti-inflammatory properties.
