RESUMEN
AIM: Specific questionnaires about food allergy and health-related quality of life (HRQoL) have been developed and validated in several languages, but not Finnish. We aimed to validate the Finnish Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF) for children under age 13 years. METHODS: The original FAQLQ-PF and Food Allergy Independent Measure (FAIM) were translated into Finnish per World Health Organisation guidelines and tested by 72 parents of children under age 13 years with suspected severe peanut or tree nut allergy who were recruited at Allergy Centre in Tampere University Hospital in Tampere, Finland. We calculated the construct validity of the questionnaire by calculating the coefficients between the two measures and used Cronbach's alpha to establish the internal consistency. RESULTS: The FAQLQ-PF showed strong correlations with domain structure and internal consistency, based on Spearman's correlations (rho) for the HRQoL questions, FAIM questions and FAIM mean values. The total questionnaire score correlated significantly with the mean FAIM (rho = 0.95, p < 0.001) and individual FAIM questions. The FAQLQ-PF and domains had good or excellent internal consistency (Cronbach's alpha >0.70). CONCLUSION: The Finnish FAQLQ-PF demonstrated good construct validity and excellent internal consistency for measuring food allergy HRQoL in children under age 13 years.

OBJECTIVE: To investigate whether the use of intrauterine tocodynamometry versus external tocodynamometry (IT versus ET) during labour reduces operative deliveries and improves newborn outcome. As IT provides more accurate information on labour contractions, the hypothesis was that it may more appropriately guide oxytocin use than ET. DESIGN: Randomised controlled trial. SETTING: Two labour wards, in a university tertiary hospital and a central hospital. POPULATION: A total of 1504 parturients with singleton pregnancies, gestational age ≥37 weeks and fetus in cephalic position: 269 women with uterine scars, 889 nulliparas and 346 parous women with oxytocin augmentation. METHODS: Participants underwent IT (n = 736) or ET (n = 768) during the active first stage of labour. MAIN OUTCOME MEASURES: Primary outcome: rate of operative deliveries. SECONDARY OUTCOMES: duration of labour, amount of oxytocin given, adverse neonatal outcomes. RESULTS: Operative delivery rates were 26.9% (IT) and 25.9% (ET) (odds ratio 1.05, 95% CI 0.84-1.32, P = 0.663). The ET to IT conversion rate was 31%. We found no differences in secondary outcomes (IT versus ET). IT reduced oxytocin use during labours with signs of fetal distress, and trial of labour after caesarean section. CONCLUSIONS: IT did not reduce the rate of operative deliveries, use of oxytocin, or adverse neonatal outcomes, and it did not shorten labour duration. TWEETABLE ABSTRACT: IT (versus ET) reduced oxytocin use in high-risk labours but did not influence operative delivery rate or adverse neonatal outcomes.

AIM: The number of colorectal cancer patients increases with age. Long-term data support personalized management due to heterogeneity within the older population. This registry- and population-based study aimed to analyse long-term survival, and causes of death, after elective colon cancer surgery in the aged, focusing on patients who survived more than 3 months postoperatively. METHODS: The data included patients ≥ 80 years who had elective surgery for Stage I-III colon cancer in four Finnish centres. The prospectively collected data included comorbidities, functional status, postoperative outcomes and long-term survival. Univariate and multivariate Cox regression analysis were conducted to determine factors associated with long-term survival. RESULTS: A total of 386 surgical patients were included, of whom 357 survived over 3 months. Survival rates for all patients at 1, 3 and 5 years were 85%, 66% and 55%, compared to 92%, 71% and 59% for patients alive 3 months postoperatively, respectively. Higher age, American Society of Anesthesiologists (ASA) score ≥ 4, Charlson Comorbidity Index ≥ 6, tumour Stage III, open compared to laparoscopic surgery and severe postoperative complications were independently associated with reduced overall survival. Higher age (hazard ratio 1.97, 1.14-3.40), diabetes (1.56, 1.07-2.27), ASA score ≥ 4 (3.27, 1.53-6.99) and tumour Stage III (2.04, 1.48-2.81) were the patient-related variables affecting survival amongst those surviving more than 3 months postoperatively. Median survival time for patients given adjuvant chemotherapy was 5.4 years, compared to 3.3 years for patients not given postoperative treatment. CONCLUSIONS: Fit aged colon cancer patients can achieve good long-term outcomes and survival with radical, minimally invasive surgical treatment, even with additional chemotherapy.

BACKGROUND: The development of total knee replacement (TKR) implant designs aims to improve outcome regarding pain, function, joint stiffness, instability, patellar problems, and ultimately wear of the implant. Recently, two major orthopaedic implant manufacturers launched a new generation of TKR implants which, according to the manufacturers, provide improved functional outcome. However, the benefits of these new TKR designs claimed by the manufacturers in terms of improved functional outcome still lack scientific documentation. The present randomized controlled trial has been designed to compare three fixed bearing, cemented cruciate-retaining (CR) designs; one of the new personalized TKR design with two conventional TKR designs with the main emphasis being on functional outcome. METHODS: The present study is a prospective, double-blinded, randomized, single-center intervention trial. A total of 240 patients will be recruited to participate in a parallel-group study at Coxa Hospital for Joint Replacement, Tampere, Finland. We will compare the short-term functional outcome of TKR performed with a novel personalized TKR design (Persona CR, Zimmer, Warsaw, IN, USA) against TKRs performed with two conventional designs (PFC CR, DePuy, Warsaw, IN, USA and Nexgen CR, Zimmer, Warsaw, IN, USA). In total, 80 patients will be randomized in each of the three study arms. The primary outcome in this study is the Oxford Knee Score (OKS), which is a validated patient-reported outcome measure (PROM). Secondary outcome measures include the Forgotten Joint Score, the 15D, the UCLA activity score, and the VAS pain scale. The results will be analyzed after 2-year follow-up. DISCUSSION: This paper presents a prospective, randomized, single-center trial study protocol. It provides details of patient randomization, PROMs, follow-up, methods of analysis of the material, and publication plan. An important aspect that will be considered in the study will be the economic effects of the novel designs as they are substantially more expensive, and the benefits of the added costs remain unknown. In addition, it is especially important to carry out evaluative studies in independent centers that are not biased by the interests of the manufacturers. TRIAL REGISTRATION: Retrospectively registered, November, 2017, ClinicalTrials.gov Identifier: NCT03339557 .

BACKGROUND: Five studies carried out after bronchiolitis at less than 24 months of age, with a follow-up of more than 10 years, reported that atopic dermatitis, family asthma, early-life exposure to tobacco smoke and rhinovirus aetiology were early-life risk factors for later asthma. This study evaluated the long-term outcome at 11-13 years of age of children who were hospitalized for bronchiolitis in early infancy. METHODS: We previously prospectively followed 166 children hospitalized for bronchiolitis at less than 6 months of age until 5-7 years of age. The current study included a structured questionnaire, parental interviews, clinical examinations and bronchodilation test of 138 of those children at 11-13 years of age. RESULTS: Respiratory syncytial virus caused 66% of the bronchiolitis cases, and nearly half of the patients were exposed to tobacco smoke in early life. Doctor-diagnosed asthma was present in 13% of the former bronchiolitis patients at 11-13 years of age. Maternal asthma was the only independently significant risk factor in early life (adjusted OR 3.45, 95% CI 1.07-11.74), as was allergic rhinitis at 5-7 years of age (adjusted OR 4.06, 95% CI 1.35-12.25). CONCLUSIONS: After bronchiolitis at less than 6 months of age, the risk of doctor-diagnosed asthma at 11-13 years was about twice that of the general Finnish population. Maternal asthma was the only independently significant early-life risk factor for current asthma at 11-13 years of age.

BACKGROUND: The survival rate of cardiac arrest patients is increasing. Our aim was to compare the quality of life before and after cardiac arrest and analyse the factors associated with outcome. METHODS: All adult cardiac arrest patients admitted to the Tampere University Hospital intensive care unit between 2009 and 2011 were included in a retrospective follow-up study if surviving to discharge and were asked to return a questionnaire after 6 months. Data on patient demographics and pre-arrest quality of life were retrieved from medical records. Data are given as means (SD) or medians [Q1 , Q3 ]. We used logistic regression to identify factors associated with better quality of life after cardiac arrest. RESULTS: Six months after cardiac arrest, 36% (79/222) were alive and 70% (55/79) of those patients completed the follow-up EuroQoL (EQ-5D) quality of life questionnaire. Median values for the EQ-5D before and after cardiac arrest were 0.89 [0.63, 1] and 0.89 [0.62, 1], respectively (P = 0.75). Only the EQ-5D prior to cardiac arrest was associated with better quality of life afterwards (OR 1.2; 95% CI 1.0-1.3; P = 0.02). CONCLUSIONS: Quality of life remained good after cardiac arrest especially in those patients who had good quality of life before cardiac arrest.

BACKGROUND: We aimed to determine the incidence of and associated risk factors for cardiopulmonary resuscitation (CPR)-related injuries in non-survivors of out-of-hospital cardiac arrests (OHCAs) in an emergency medical service (EMS) system in which all CPR procedures are performed on scene and patients are not routinely transported to the hospital with ongoing CPR. MATERIAL AND METHODS: We conducted this prospective observational study between 1 June 2013, and 31 May 2014. Data were collected from EMS datasheets and forensic autopsy records. The exclusion criteria were OHCAs due to trauma in the thoracic or abdominal area. EMS adhered to the European Resuscitation Council Resuscitation Guidelines (2010) during the resuscitation attempts. RESULTS: Emergency medical service provided CPR in 280 attended OHCAs with 207 cases terminated on scene. A total of 149 patients underwent a forensic autopsy and 47% had a CPR-related injury. The most common injuries were multiple rib fractures (43%), with 22% of patients having more than eight fractured ribs. Abdominal visceral injuries or injuries related to airway management were rare. The injuries were associated with older age, male gender, initial shockable rhythm and public location of the cardiac arrest (P < .05 respectively). In the multivariable regression analysis, older age, male gender, and public location were independent predictors for injuries. There were no differences in the durations of the CPR attempt between the injured and non-injured groups. CONCLUSION: Older age, male gender, and public location were independently associated with CPR-related injuries. The duration of the resuscitation attempts did not affect the incident of injuries.

BACKGROUND: Dispatching Emergency Medical Services to treat patients with deteriorating health in nursing homes and primary care facilities is common in Finland. We examined the cardiac arrest patients to describe this phenomenon. We had a special interest in patients for whom cardiopulmonary resuscitation was considered futile. METHODS: We conducted an observational study between 1 June 2013 and 31 May 2014 in the Pirkanmaa area. We included cases in which Emergency Medical Services participated in the treatment of cardiac arrest patients in nursing homes and primary care facilities. RESULTS: Emergency Medical Services attended to a total of 355 cardiac arrest patients, and 65 patients (18%) met the inclusion criteria. The included patients were generally older than 65 years, but otherwise heterogeneous. Nineteen patients (29%) had a valid do-not-attempt-resuscitation order, but paramedics were not informed about it in 10 (53%) of those cases. Eight (12%) of the 65 patients survived to hospital admission and 3 (5%) survived to hospital discharge with a neurologically favourable outcome. Two patients were alive 90 days after the cardiac arrest; both were younger than 70 years of age and had ventricular fibrillation as primary rhythm. There were no survivors in nursing homes. CONCLUSIONS: The do-not-attempt-resuscitation orders were often unavailable during a cardiopulmonary resuscitation attempt. Although resuscitation attempts were futile for patients in nursing homes, some patients in primary care facilities demonstrated a favourable outcome after cardiac arrest. Emergency Medical Services seem to be able to recognise potential survivors and focus resources on their treatment.

We have previously shown that sensitizations to several types of allergens distinguish subjects with and without adult-onset asthma in Finland. The aim was to analyze how age affects sensitization and asthma risk. We used previous population-based case-control data (N=456) from Finnish adult asthma patients with one or two matched controls. Asthma was diagnosed based on a typical history of asthmatic symptoms and lung function tests. Allergic sensitization was determined by skin prick test (SPT) to 17 aeroallergens. Information on demographics was obtained by a questionnaire. Sensitization to more than one allergen type and the number of positive SPT reactions associated with younger age and asthma. Atopic subjects aged 65 and above were characterized by sensitization to only one to two allergens, with very few animal danders and without an association with asthma. Multiple sensitizations and animal dander sensitization are more common among Finnish asthmatic adults aged under 56 than among older asthmatics. Cohort studies are needed to understand timing of host-environmental interactions behind this.

OBJECTIVES: Chronic rhinosinusitis with and without nasal polyps (CRSwNP and CRSsNP) and antrochoanal polyps (ACP) are different upper airway inflammation phenotypes with different pathomechanisms. In order to understand the development of tissue edema, the present study aimed to evaluate lymphatic vessel density in CRSsNP, CRSwNP and ACP. MATERIALS AND METHODS: 120 retrospective nasal and maxillary sinus specimens were stained immunohistochemically with a von Willebrand factor polyclonal antibody recognizing vascular and lymphatic endothelium, and with a podoplanin monoclonal antibody recognizing lymphatic endothelium. Vessels were studied by microscopy in a blinded fashion, and the vessel density and the relative density of lymphatic vessels were calculated. Patient characteristic factors and follow-up data of in average 9 years were collected from patient records. RESULTS AND CONCLUSION: In the nasal cavity, the low absolute and relative density of vessels and of lymphatic vessels was associated with CRSwNP and ACP tissues compared to control inferior turbinate. This was observed also in the inflammatory hotspot area. In the maxillary sinus, lower absolute and relative density of lymphatic vessels associated with the CRSwNP phenotype. High lymphatic vessel density in polyp tissue associated with the need for revision CRS-surgery. As a conclusion, low density of lymphatic vessels distinguished patients with CRSwNP not only in the hotspot area of polyp tissue, but also in maxillary sinus mucosa. Yet, higher lymphatic vessel density seems to associate with polyp recurrence. Further studies are still needed to explore if formation of nasal polyps could be diminished by intranasal therapeutics affecting lymphangiogenesis.

BACKGROUND: Persistent post-sternotomy pain is a common problem, but the risk of developing it varies among patients. We sought to find out whether the risk of persistent post-sternotomy pain could be predicted by measuring the area of acute sensory dysfunction around the sternotomy wound. The secondary aim was to determine risk factors for persistent post-sternotomy pain. PATIENTS AND METHODS: Hundred patients who were scheduled to undergo elective coronary artery bypass surgery were recruited to the study. Patients were excluded if they had undergone previous cardiac surgery or if they lacked co-operation. Preoperative pain scores were determined and the patients filled in questionnaires about depression, anxiety, and pain. The area of sensory dysfunction around the sternotomy wound was assessed by pin prick on postoperative day 4. The presence of persistent post-sternotomy pain was determined at a follow-up evaluation at 4-6 months after surgery. RESULTS: The sizes of the area of hyperalgesia or overall sensory dysfunction were not associated with persistent post-sternotomy pain. Independent risk factors for persistent post-sternotomy pain were found to be smoking and high pain score on postoperative day 1. The prevalence of persistent post-sternotomy pain in our study population was 38% analyzed by only the questionnaire and 15% according to the clinical examination. CONCLUSION: Measuring the area of hyperalgesia in the acute phase does not give any additional information on the risk of developing a persistent post-sternotomy pain. We do thus not recommend measuring the area in this particular group of patients. Evaluation of pain by only a questionnaire risks to overestimate the presence of persistent post-sternotomy pain as compared to clinical examination.

BACKGROUND: The prevalence of persistent post-sternotomy pain (PPSP) varies largely and has been mainly studied using questionnaires. We decided to perform a systematic qualitative and quantitative sensory examination study on a power-calculated sample of patients who had undergone sternotomy for cardiac surgery. Pain was diagnosed as PPSP if the patient complained of sternal pain that had developed after surgery together with corresponding sensory disturbances. PATIENTS AND METHODS: One hundred elective patients undergoing coronary artery bypass via sternotomy were recruited for dynamic sensory mapping 4-6 months after surgery. Sensory testing was performed using thermal rollers, a cotton stick and pinprick. The intensity of sensation was registered as a score on a numeric rating scale. The area of sensory dysfunction on the chest wall was traced onto paper and calculated with the help of a computer-based program. The patient also answered a validated pain questionnaire. RESULTS: Altogether 90 patients took part in the examination. Thirteen (15.4%) of the patients had pain and formed the PPSP group, while the remaining patients formed the non-PPSP group. Both groups had sensory abnormalities over the chest wall (69% of all patients). Sensory disturbances were more common, more profound and extended over a larger skin area in the PPSP group. Furthermore, daily activity performance in the PPSP group was poorer compared to the non-PPSP group. CONCLUSION: PPSP is a clinical diagnosis easily achieved using simple diagnostic tools and a medical history. Severity and extent of sensory abnormalities were found to be greater in the PPSP group.

PURPOSE: The aim of this study was to study the effect of the embryo freezing method on the birth weight of newborns from frozen embryo transfer (FET) cycles, and the pregnancy results of cleavage stage embryos cryopreserved by slow freezing or vitrification. METHODS: This is a retrospective cohort study undertaken in a University Hospital IVF unit using concurrently both the slow-freezing and the vitrification techniques. All frozen-thawed and vitrified-warmed day 2 and day 3 embryo transfers during the time period from 1 April 2009 to 31 November 2013 were included in the study. RESULTS: There was no statistically significant weight difference between newborns from vitrified or slow-frozen embryos (3588 vs 3670 g). A higher post-thaw viability rate was achieved after cryopreservation by the vitrification technique compared to the slow-freezing protocol (83.4 vs 61.4%). The miscarriage rate was lower in the vitrification group (15.7 vs 29.0%). The live birth rates were similar (19.5 vs 19.1%) in the slow-freezing and vitrification groups, respectively. Among vitrified embryos, 7.4 embryos needed to be thawed to produce one delivery; in the slow-freezing group, that number was 11.9. CONCLUSIONS: The freezing method has no impact on the weight of the newborn. With lower post-thaw survival rates and higher miscarriage rates, the slow-freezing cryopreservation protocol is inferior to the vitrification technique.

STUDY QUESTION: Does extended embryo culture have a different effect on the birthweight of girls and boys? SUMMARY ANSWER: The mean birthweight of boys born after fresh and frozen-thawed blastocyst transfer was increased compared with those born after cleavage stage embryo transfer. This effect was not detected among girls. WHAT IS KNOWN ALREADY: Previous studies indicate that newborns from frozen-thawed cleavage stage embryos may present with a higher weight than newborns from fresh embryo transfers. With regard to fresh embryos, newborns after a blastocyst transfer have been reported as having higher birthweights than newborns from cleavage stage embryos. STUDY DESIGN, SIZE, DURATION: Retrospective multicentre case-control cohort study. All IVF/ICSI treatments were performed in the time-period from January 2008 to March 2014. PARTICIPANTS/MATERIALS, SETTING, METHODS: Birthweight of singletons born at full-term (≥37 weeks), after fresh or frozen blastocyst embryo transfers (n = 277), were compared with weights of children born after fresh or frozen cleavage stage embryo transfers (Day 2-3) (n = 277). The cases and controls were matched by delivery week, and by gender. Data of IVF/ICSI treatments, and the treatments' outcomes were collected and analysed. MAIN RESULTS AND THE ROLE OF CHANCE: The birthweight after a fresh blastocyst transfer was significantly higher (mean 3530.6 g) than that after a transfer of cleavage stage embryos (mean 3418.8 g; weight difference 111.8 g, P = 0.047). The weights of newborns after frozen-thawed blastocyst transfers (mean 3647.5 g) and the frozen-thawed cleavage stage embryo transfers (mean 3650.9 g), were similar (weight difference 3.4 g, P = 0.95). The boys born after transfer of frozen-thawed blastocysts had a significantly higher birthweight (mean 3767.9 g) than girls (3525.2 g; weight difference 242.7 g, P = 0.002), whereas the difference of birthweights between genders was only 13.5 g in cleavage stage (P = 0.863). The same effect was seen after fresh blastocyst transfers (weight difference 211.5 g, P = 0.011), but not after fresh Day 2-3 embryo transfers (weight difference 53.6 g, P = 0.478). LIMITATIONS, REASONS FOR CAUTION: The study material was large enough to detect differences between birthweights as a whole, but a larger study group would confirm these new findings. To avoid selection bias, the next possible control candidate, fulfilling the selection criteria, was included for matching cases and controls. We have matched the cases and controls by gender and gestational week at birth, with an aim to reduce their impact as confounding factors. WIDER IMPLICATIONS OF THE FINDINGS: Our findings of a similar weight at birth of newborns after frozen-thawed blastocysts and frozen-thawed cleavage stage embryos, when matching for age and duration of pregnancy, are novel. The gender of the newborn has an impact on the birthweight, and the extended embryo culture increases the weight difference between the genders, which is a new finding as well. STUDY FUNDING/COMPETING INTERESTS: The study was funded by the Fertility Society of Finland.

BACKGROUND: There is a large global variation in the sensitization pattern and its association with allergic diseases. In temperate and tropical urban environments, mite monosensitization can be the predominant cause of allergic airway diseases, whereas in other environments, polysensitization is more typical. Sensitization to mite allergens associates with asthma. However, it is suggested that mite sensitization might play a minor role in Northern Europe. The aim of the study was to analyze how sensitization pattern affects the asthma risk in Finnish adults, with a special focus on mites. METHODS: A population-based case-control data (N = 523) from Finnish adult asthma patients with one or two matched controls were used. Asthma was diagnosed based on a typical history of asthmatic symptoms and lung function tests. The allergic sensitization was determined based on skin prick test (SPT) of five mites, three molds, and nine other aeroallergens. Information on demographics was obtained by a questionnaire. RESULTS: The proportion of sensitization to any allergen was 55% in the asthma group and 39% in the control group (P = 0.001, OR 2.06, 95% CI = 1.35-3.14). Sensitization to animal dander, pollen, or Aspergillus fumigatus was associated with asthma. Polysensitization to more than one allergen types and the number of SPT-positive reactions associated with asthma, whereas sensitization to only one allergen type was not associated with asthma. CONCLUSIONS: The large number of sensitizations to several types of allergens distinguishes subjects with asthma. Mite sensitization had little independent association with asthma in Finland.

BACKGROUND: Concomitantly recorded Bispectral Index® (BIS) and Entropy™ values sometimes show discordant trends during general anaesthesia. Previously, no attempt had been made to discover which EEG characteristics cause discrepancies between BIS and Entropy. We compared BIS and Entropy values, and analysed the changes in the raw EEG signal during surgical anaesthesia with sevoflurane. METHODS: In this prospective, open-label study, 65 patients receiving general anaesthesia with sevoflurane were enrolled. BIS, Entropy and multichannel digital EEG were recorded. Concurrent BIS and State Entropy (SE) values were selected. Whenever BIS and SE values showed ≥10-unit disagreement for ≥60 s, the raw EEG signal was analysed both in time and frequency domain. RESULTS: A ≥10-unit disagreement ≥60 s was detected 428 times in 51 patients. These 428 episodes accounted for 5158 (11%) out of 45 918 analysed index pairs. During EEG burst suppression, SE was higher than BIS in 35 out of 49 episodes. During delta-theta dominance, BIS was higher than SE in 141 out of 157 episodes. During alpha or beta activity, SE was higher than BIS in all 49 episodes. During electrocautery, both BIS and SE changed, sometimes in the opposite direction, but returned to baseline values after electrocautery. Electromyography caused index disagreement four times (BIS > SE). CONCLUSIONS: Certain specific EEG patterns, and artifacts, are associated with discrepancies between BIS and SE. Time and frequency domain analyses of the original EEG improve the interpretation of studies involving BIS, Entropy and other EEG-based indices.

BACKGROUND: Medical emergency team (MET) activation criteria serve as a predictor of serious adverse events on hospital wards and in the emergency department (ED). We aimed to determine whether in-hospital MET activation criteria would be useful in identifying patients at risk in pre-hospital care. METHODS: The data were collected retrospectively from 610 adult patients treated by physician-staffed helicopter emergency medical services. Pre-hospital vital signs were compared with MET activation criteria and scored accordingly to receive a simplified pre-hospital 'MET' score. The primary outcome measure was hospital mortality. The secondary outcome measures were admission to intensive care unit and the length of ED stay, intensive care unit (ICU) stay and hospital stay. The simplified pre-hospital 'MET' score was also compared with Emergency Severity Index (ESI) used as a triage tool in ED. RESULTS: Higher simplified pre-hospital 'MET' scores were associated with hospital mortality (P<0.001), the need for ICU treatment (P<0.001) and a more urgent ESI class in the ED (P<0.001). Higher simplified pre-hospital 'MET' scores were associated with shorter stay in the ED (P<0.001), longer stay in the ICU (P<0.001) and longer hospital stay (P<0.001). A simplified pre-hospital 'MET' score was an independent predictor for hospital mortality (odds ratio 2.42, confidence interval 1.84 3.18, P<0.001), regardless of age or patient's previous overall physical health classified by American Society of Anesthesiologists physical status classification system. CONCLUSION: A simplified pre-hospital 'MET' score is a predictor for patient outcome and could serve as a risk assessment tool for the health care provider on-scene.

BACKGROUND: The aim of physician staffed emergency medical services (EMS) is to supplement other EMS units in the care of prehospital patients. The need for advanced airway management in critical prehospital patients can be considered as one indicator of the severity of the patient's condition. Our primary aim was to study the long-term outcome of critically ill patients (excluding cardiac arrest) who were intubated by EMS physicians in the prehospital setting. METHODS: Data of 845 patients, whose airways were secured by the EMS physicians during a 5-year (2007-2011) period, were retrospectively evaluated. After exclusions, the outcome of 483 patients (8.9% of all patients treated by EMS) was studied. Evaluation was based on hospital patient records 1 year after the incident. For assessment of neurological outcome, a modified Glasgow Outcome Score (GOS) was used. Time and cause of death were recorded. RESULTS: 55.3% of the study patients had a good neurological recovery (GOS 4-5) with independent life 1 year after the event. The overall 1-year mortality (GOS 1) was 35.0%. Poor neurological outcome (GOS 2-3) was found in 9.7% of the patients. Patients with intoxication or convulsions survived best, while those with suspected intracranial pathology had the worst prognosis. Of all survivors, 85% recovered well. CONCLUSION: The majority of the study patients had a favourable neurological recovery with independent life at 1 year after the incident. More than 80% of all deaths occurred within 30 days of the incident.

OBJECTIVES: Self- and informant reports of patients' cognitive performance are an important source of information for clinicians to consider in neuropsychological evaluation. The aim of the study was to find out whether the relationship between subjective or informant observations of cognitive deterioration and objective cognitive performance differ in patients with relapsing and progressive multiple sclerosis (MS). MATERIALS & METHODS: One ninety-six MS patients (relapsing-remitting n = 138; progressive n = 58) underwent neuropsychological assessment with the Brief Repeatable Battery of Neuropsychological Tests. Subjective and informant-reported cognitive symptoms, mood, impact of the disease, and quality of life were evaluated with self-reports. According to consistency of evaluations, patients and informants were classified as accurate estimators (consistent subjective and objective cognitive performance), underestimators (subjectively but not objectively cognitively impaired), or overestimators (objectively but not subjectively cognitively impaired). RESULTS: Patients' and informants' reports on patients' cognitive performance were approximately equally appropriate, slightly over half being accurate. Mood was associated with patients' subjective cognitive complaints. The relapsing group reported more subjective cognitive symptoms than the progressive group, although the objective cognitive performance did not differ between the groups. Overestimation occurred especially among patients with more severe physical disability, progressive phenotype of the disease, more pronounced cognitive impairment, and less education. CONCLUSIONS: Slightly over half of patient and informant observations of cognitive deterioration were appropriate. Patients with progressive phenotype were more prone to overestimation than patients with relapsing phenotype.
