Growing rods in meningomyelocele lead to increased risk for complications in comparison with fusion; a retrospective study of 30 patients treated for at the University Hospital of Uppsala.

PURPOSE: To compare the complication rates of two different types of posterior instrumentation in patients with MMC, namely, definitive fusion and fusionless surgery (growing rods). METHODS: Single-center retrospective study of 30 MMC patients that underwent posterior instrumentation for deformity (scoliosis and/or kyphosis) treatment from 2008 until 2020. The patients were grouped based on whether they received definitive fusion or a growth-accommodating system, whether they had a complication that led to early surgery, osteotomy or non-osteotomy. Number of major operations, Cobb angle correction and perioperative blood loss were the outcomes. RESULTS: 18 patients received a growing system and 12 were fused at index surgery. The growing system group underwent a mean of 2.38 (± 1.03) surgeries versus 1.91 (± 2.27) in the fusion group, p = 0.01. If an early revision was necessitated due to a complication, then the number of major surgeries per patient was 3.37 (± 2.44) versus 1.77 (± 0.97) in the group that did not undergo an early revision, p = 0.01. Four patients developed a superficial and six a deep wound infection, while loosening/breakage occurred in 10 patients. The Cobb angle was improved from a mean of 69 to 22 degrees postoperatively. Osteotomy did not lead to an increase in perioperative blood loss or number of major operations. CONCLUSION: Growing systems had more major operations in comparison with fusion surgery and early revision surgery led to higher numbers of major operations per patient; these differences were statistically significant. Definitive fusion at index surgery might be the better option in some MMC patients with a high-risk profile.

Decompression alone or decompression with fusion for lumbar spinal stenosis: a randomized clinical trial with two-year MRI follow-up.

AIMS: The aims of this study were first, to determine if adding fusion to a decompression of the lumbar spine for spinal stenosis decreases the rate of radiological restenosis and/or proximal adjacent level stenosis two years after surgery, and second, to evaluate the change in vertebral slip two years after surgery with and without fusion. METHODS: The Swedish Spinal Stenosis Study (SSSS) was conducted between 2006 and 2012 at five public and two private hospitals. Six centres participated in this two-year MRI follow-up. We randomized 222 patients with central lumbar spinal stenosis at one or two adjacent levels into two groups, decompression alone and decompression with fusion. The presence or absence of a preoperative spondylolisthesis was noted. A new stenosis on two-year MRI was used as the primary outcome, defined as a dural sac cross-sectional area ≤ 75 mm2 at the operated level (restenosis) and/or at the level above (proximal adjacent level stenosis). RESULTS: A total of 211 patients underwent surgery at a mean age of 66 years (69% female): 103 were treated by decompression with fusion and 108 by decompression alone. A two-year MRI was available for 176 (90%) of the eligible patients. A new stenosis at the operated and/or adjacent level occurred more frequently after decompression and fusion than after decompression alone (47% vs 29%; p = 0.020). The difference remained in the subgroup with a preoperative spondylolisthesis, (48% vs 24%; p = 0.020), but did not reach significance for those without (45% vs 35%; p = 0.488). Proximal adjacent level stenosis was more common after fusion than after decompression alone (44% vs 17%; p < 0.001). Restenosis at the operated level was less frequent after fusion than decompression alone (4% vs 14%; p = 0.036). Vertebral slip increased by 1.1 mm after decompression alone, regardless of whether a preoperative spondylolisthesis was present or not. CONCLUSION: Adding fusion to a decompression increased the rate of new stenosis on two-year MRI, even when a spondylolisthesis was present preoperatively. This supports decompression alone as the preferred method of surgery for spinal stenosis, whether or not a degenerative spondylolisthesis is present preoperatively.Cite this article: Bone Joint J 2022;104-B(12):1343-1351.

Outcome prediction for patients assessed by the medical emergency team: a retrospective cohort study.

BACKGROUND: Medical emergency teams (METs) have been implemented to reduce hospital mortality by the early recognition and treatment of potentially life-threatening conditions. The objective of this study was to establish a clinically useful association between clinical variables and mortality risk, among patients assessed by the MET, and further to design an easy-to-use risk score for the prediction of death within 30 days. METHODS: Observational retrospective register study in a tertiary university hospital in Sweden, comprising 2,601 patients, assessed by the MET from 2010 to 2015. Patient registry data at the time of MET assessment was analysed from an epidemiological perspective, using univariable and multivariable analyses with death within 30 days as the outcome variable. Predictors of outcome were defined from age, gender, type of ward for admittance, previous medical history, acute medical condition, vital parameters and laboratory biomarkers. Identified factors independently associated with mortality were then used to develop a prognostic risk score for mortality. RESULTS: The overall 30-day mortality was high (29.0%). We identified thirteen factors independently associated with 30-day mortality concerning; age, type of ward for admittance, vital parameters, laboratory biomarkers, previous medical history and acute medical condition. A MET risk score for mortality based on the impact of these individual thirteen factors in the model yielded a median (range) AUC of 0.780 (0.774-0.785) with good calibration. When corrected for optimism by internal validation, the score yielded a median (range) AUC of 0.768 (0.762-0.773). CONCLUSIONS: Among clinical variables available at the time of MET assessment, thirteen factors were found to be independently associated with 30-day mortality. By applying a simple risk scoring system based on these individual factors, patients at higher risk of dying within 30 days after the MET assessment may be identified and treated earlier in the process.

Preoperative MRI and Intraoperative Monitoring Differentially Prevent Neurological Sequelae in Idiopathic Scoliosis Surgical Correction, While Curves >70 Degrees Increase the Risk of Neurophysiological Incidences

The aim was to investigate the role of preoperative magnetic resonance imaging (MRI) and intraoperative monitoring (IOM) in the prevention of correction-related complications in idiopathic scoliosis (IS). We conducted a retrospective case study of 129 patients with juvenile and adolescent IS. The operations took place between 2005 and 2018 in Uppsala University Hospital. Data from MRI scans and IOM were collected. The patients were divided into groups depending on Lenke's classification, sex, major curve (MC) size, and onset age. Neurophysiological incidences were reported in ten patients (7.8%), while nine of them had no signs of intraspinal pathology. Six patients (4.7%) had transient incidences; however, in four patients (3.1%), an intervention was required for the normalization of action potentials. Three of them had an MC >70 degrees, which was significantly higher than the expected value. Eight patients (6.1%) had intraspinal pathologies, and two of them (1.5%) underwent decompression. We suggest the continuation of MRI screening preoperatively and, most importantly, the use of IOM. In three cases with no signs of pathology in the MRI, IOM prevented possible neurological injuries. MCs >70 degrees should be considered a risk factor for the occurrence of neurophysiological deficiencies that require action to be normalized.

Effects of Cardiac Rehabilitation on Physical Fitness, Physical Function, and Self-reported Outcomes in Patients ≥80 yr: A RANDOMIZED CONTROLLED TRIAL.

PURPOSE: The beneficial effects of exercise-based cardiac rehabilitation (CR) after an acute coronary syndrome (ACS) are well known, but patients ≥80 yr have been less studied. The aim was to evaluate the effects of CR on patients with ACS ≥80 yr on peak cardiorespiratory fitness (CRF), physical function, and patient-reported outcome measures (PROMs) compared with a control group. METHODS: A total of 26 patients with ACS, median age 82 (81, 84) yr, were randomized to hospital-based CR combined with a home-based exercise program (CR group) or to a control group (C) for 4 mo. Outcomes were assessed at baseline and 4 mo and included the peak CRF (primary outcome), 6-min walk test (6MWT), muscle endurance, Timed Up and Go (TUG), Short Physical Performance Battery (SPPB), one-leg stand test, and PROMs. RESULTS: There were no significant differences between the groups in peak CRF. The CR group improved significantly in terms of the 6MWT ( P = .04), isotonic muscle endurance ( P < .001), one-leg stand test ( P = .001), SPPB total score ( P =.03), Activities-specific Balance Confidence ( P =.01), and anxiety ( P =.03), as compared with C. There were no significant intergroup differences in the TUG, the self-reported health question or depression. CONCLUSIONS: Patients with ACS ≥80 yr improved in walking distance, muscle endurance, physical function, and PROMs, but not in peak CRF, by participating in a CR program. These results suggest an increased referral to CR for this growing group of patients to enable preserved mobility and independence in daily living, but this needs to be confirmed in larger studies.

Predictors of short- and long-term mortality in critically ill, older adults admitted to the emergency department: an observational study.

BACKGROUND: In the future, we can expect an increase in older patients in emergency departments (ED) and acute wards. The main purpose of this study was to identify predictors of short- and long-term mortality in the ED and at hospital discharge. METHODS: This is a retrospective, observational, single-center, cohort study, involving critically ill older adults, recruited consecutively in an ED. The primary outcome was mortality. All patients were followed for 6.5-7.5 years. The Cox proportional hazards model was used. RESULTS: Regarding all critically ill patients aged ≥ 70 years and identified in the ED (n = 402), there was a significant association between mortality at 30 days after ED admission and unconsciousness on admission (HR 3.14, 95% CI 2.09-4.74), hypoxia on admission (HR 2.51, 95% CI 1.69-3.74) and age (HR 1.06 per year, 95% CI 1.03-1.09), (all p < 0.001). Of 402 critically ill patients aged ≥ 70 years and identified in the ED, 303 were discharged alive from hospital. There was a significant association between long-term mortality and the Charlson Comorbidity Index (CCI) > 2 (HR 1.90, 95% CI 1.46-2.48), length of stay (LOS) > 7 days (HR 1.72, 95% CI 1.32-2.23), discharge diagnosis of pneumonia (HR 1.65, 95% CI 1.24-2.21) and age (HR 1.08 per year, 95% CI 1.05-1.10), (all p < 0.001). The only symptom or vital sign associated with long-term mortality was hypoxia on admission (HR 1.70, 05% CI 1.30-2.22). CONCLUSIONS: Among critically ill older adults admitted to an ED and discharged alive the following factors were predictive of long-term mortality: CCI > 2, LOS > 7 days, hypoxia on admission, discharge diagnosis of pneumonia and age. The following factors were predictive of mortality at 30 days after ED admission: unconsciousness on admission, hypoxia and age. These data might be clinically relevant when it comes to individualized care planning, which should take account of risk prediction and estimated prognosis.

Learning Outcome After Different Combinations of Seven Learning Activities in Basic Life Support on Laypersons in Workplaces: a Cluster Randomised, Controlled Trial.

BACKGROUND: The goal for laypersons after training in basic life support (BLS) is to act effectively in an out-of-hospital cardiac arrest situation. However, it is still unclear whether BLS training targeting laypersons at workplaces is optimal or whether other effective learning activities are possible. AIM: The primary aim was to evaluate whether there were other modes of BLS training that improved learning outcome as compared with a control group, i.e. standard BLS training, six months after training, and secondarily directly after training. METHODS: In this multi-arm trial, lay participants (n = 2623) from workplaces were cluster randomised into 16 different BLS interventions, of which one, instructor-led and film-based BLS training, was classified as control and standard, with which the other 15 were compared. The learning outcome was the total score for practical skills in BLS calculated using the modified Cardiff Test. RESULTS: Four different training modes showed a significantly higher total score compared with standard (mean difference 2.3-2.9). The highest score was for the BLS intervention including a preparatory web-based education, instructor-led training, film-based instructions, reflective questions and a chest compression feedback device (95% CI for difference 0.9-5.0), 6 months after training. CONCLUSION: BLS training adding several different combinations of a preparatory web-based education, reflective questions and chest compression feedback to instructor-led training and film-based instructions obtained higher modified Cardiff Test total scores 6 months after training compared with standard BLS training alone. The differences were small in magnitude and the clinical relevance of our findings needs to be further explored. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03618888.

Nuclear upregulation of class I phosphoinositide 3-kinase p110ß correlates with high 47S rRNA levels in cancer cells.

The class I phosphoinositide 3-kinase (PI3K) catalytic subunits p110α and p110ß are ubiquitously expressed but differently targeted in tumours. In cancer, PIK3CB (encoding p110ß) is seldom mutated compared with PIK3CA (encoding p110α) but can contribute to tumorigenesis in certain PTEN-deficient tumours. The underlying molecular mechanisms are, however, unclear. We have previously reported that p110ß is highly expressed in endometrial cancer (EC) cell lines and at the mRNA level in primary patient tumours. Here, we show that p110ß protein levels are high in both the cytoplasmic and nuclear compartments in EC cells. Moreover, high nuclear:cytoplasmic staining ratios were detected in high-grade primary tumours. High levels of phosphatidylinositol (3,4,5)-trisphosphate [PtdIns(3,4,5)P3] were measured in the nucleus of EC cells, and pharmacological and genetic approaches showed that its production was partly dependent upon p110ß activity. Using immunofluorescence staining, p110ß and PtdIns(3,4,5)P3 were localised in the nucleolus, which correlated with high levels of 47S pre-rRNA. p110ß inhibition led to a decrease in both 47S rRNA levels and cell proliferation. In conclusion, these results present a nucleolar role for p110ß that may contribute to tumorigenesis in EC.This article has an associated First Person interview with Fatemeh Mazloumi Gavgani, joint first author of the paper.

Plasma renin activity has a complex prognostic role in patients with acute coronary syndromes.

BACKGROUND: Plasma renin activity (PRA) has been related to all-cause mortality and cardiovascular events in patients with cardiovascular disease. However, data from patients with acute coronary syndromes (ACS) are sparse. METHODS: Determination of PRA was made in 550 patients with ACS, including a subgroup of 287 patients not on treatment with angiotensin converting enzyme inhibitors, angiotensin receptor blockers or diuretics, and without heart failure. We evaluated the relations between PRA and all-cause mortality after three years and long-term, and to cardiovascular events after median 8.7 years. Adjustments were made for variables that influenced the hazard ratio (HR) > 5% for the relation between PRA and outcome. RESULTS: Baseline PRA was associated with all-cause mortality during three-years (unadjusted HR 1.74 per 1 SD increase in logarithmically transformed PRA; 95% confidence interval (CI) 1.39-2.16, p < 0.0001) and long-term (HR 1.12, CI 1.00-1.25, p = 0.046). After adjustments, only the three-year association remained significant. In unadjusted analyses, PRA was associated with cardiovascular death, but not with nonfatal cardiovascular events. In the subgroup there was an inverse relation between PRA and long-term all-cause mortality. CONCLUSION: Higher PRA was a significant independent predictor of all-cause mortality after three years, but not at long-term follow-up and not significantly associated with cardiovascular incidence. The renin-angiotensin-system pathophysiology is of great interest, not least due to its association with the COVID-19 pandemic. Our findings indicate a need for further research on the prognostic/predictive aspects of the renin-angiotensin-system in ACS.

Similar Profile and Magnitude of Cognitive Impairments in Focal and Generalized Epilepsy: A Pilot Study.

Introduction: Cognitive impairments in epilepsy are not well-understood. In addition, long-term emotional, interpersonal, and social consequences of the underlying disturbances are important to evaluate. Purpose: To compare cognitive function including language in young adults with focal or generalized epilepsy. In addition, quality of life and self-esteem were investigated. Patients and Methods: Young adults with no primary intellectual disability, 17 with focal epilepsy and 11 with generalized epilepsy participated and were compared to 28 healthy controls. Groups were matched on age (mean = 26 years), sex, and education. Participants were administered a battery of neuropsychological tasks and carried out self-ratings of quality of life, self-esteem, and psychological problems. Results: Similar impairments regarding cognitive function were noted in focal and generalized epilepsy. The cognitive domains tested were episodic long-term memory, executive functions, attention, working memory, visuospatial functions, and language. Both epilepsy groups had lower results compared to controls (effect sizes 0.24-1.07). The total number of convulsive seizures was predictive of episodic long-term memory function. Participants with focal epilepsy reported lower quality of life than participants with generalized epilepsy. Lowered self-esteem values were seen in both epilepsy groups and particularly in those with focal epilepsy. Along with measures of cognitive speed and depression, the total number of seizures explained more than 50% of variation in quality of life. Conclusion: Interestingly, similarities rather than differences characterized the widespread cognitive deficits that were seen in focal and generalized epilepsy, ranging from mild to moderate. These similarities were modified by quality of life and self-esteem. This study confirms the notion that epilepsy is a network disorder.

Association between inflammatory response and outcome after subarachnoid haemorrhage.

OBJECTIVES: Recent reports suggest an association between the inflammatory response after aneurysmal subarachnoid haemorrhage (aSAH) and patients' outcome. The primary aim of this study was to identify a potential association between the inflammatory response after aSAH and 1-year outcome. The secondary aim was to investigate whether the inflammatory response after aSAH could predict the development of delayed cerebral ischaemia (DCI). MATERIALS AND METHODS: This prospective observational pilot study included patients with an aSAH admitted to Sahlgrenska University Hospital, Gothenburg, Sweden, between May 2015 and October 2016. The patients were stratified according to the extended Glasgow Outcome Scale (GOSE) as having an unfavourable (score: 1-4) or favourable outcome (score: 5-8). Furthermore, patients were stratified depending on development of DCI or not. Patient data and blood samples were collected and analysed at admission and after 10 days. RESULTS: Elevated serum concentrations of inflammatory markers such as tumour necrosis factor-α and interleukin (IL)-6, IL-1Ra, C-reactive protein and intercellular adhesion molecule-1 were detected in patients with unfavourable outcome. When adjustments for Glasgow coma scale were made, only IL-1Ra remained significantly associated with poor outcome (p = 0.012). The inflammatory response after aSAH was not predictive of the development of DCI. CONCLUSION: Elevated serum concentrations of inflammatory markers were associated with poor neurological outcome 1-year after aSAH. However, inflammatory markers are affected by many clinical events, and when adjustments were made, only IL-1Ra remained significantly associated with poor outcome. The robustness of these results needs to be tested in a larger trial.

Pre-hospital predictors of an adverse outcome among patients with dyspnoea as the main symptom assessed by pre-hospital emergency nurses - a retrospective observational study.

BACKGROUND: Dyspnoea is one of the most common reasons for patients contacting emergency medical services (EMS). Pre-hospital Emergency Nurses (PENs) are independently responsible for advanced care and to meet these patients individual needs. Patients with dyspnoea constitute a complex group, with multiple different final diagnoses and with a high risk of death. This study aimed to describe on-scene factors associated with an increased risk of a time-sensitive final diagnosis and the risk of death. METHODS: A retrospective observational study including patients aged ≥16 years, presenting mainly with dyspnoea was conducted. Patients were identified thorough an EMS database, and were assessed by PENs in the south-western part of Sweden during January to December 2017. Of 7260 missions (9% of all primary missions), 6354 were included. Among those, 4587 patients were randomly selected in conjunction with adjusting for unique patients with single occasions. Data were manually collected through both EMS- and hospital records and final diagnoses were determined through the final diagnoses verified in hospital records. Analysis was performed using multiple logistic regression and multiple imputations. RESULTS: Among all unique patients with dyspnoea as the main symptom, 13% had a time-sensitive final diagnosis. The three most frequent final time-sensitive diagnoses were cardiac diseases (4.1% of all diagnoses), infectious/inflammatory diseases (2.6%), and vascular diseases (2.4%). A history of hypertension, renal disease, symptoms of pain, abnormal respiratory rate, impaired consciousness, a pathologic ECG and a short delay until call for EMS were associated with an increased risk of a time-sensitive final diagnosis. Among patients with time-sensitive diagnoses, approximately 27% died within 30 days. Increasing age, a history of renal disease, cancer, low systolic blood pressures, impaired consciousness and abnormal body temperature were associated with an increased risk of death. CONCLUSIONS: Among patients with dyspnoea as the main symptom, age, previous medical history, deviating vital signs, ECG pattern, symptoms of pain, and a short delay until call for EMS are important factors to consider in the prehospital assessment of the combined risk of either having a time-sensitive diagnosis or death.

Experiences of awake surgery in non-tumoural epilepsy in eloquent localizations.

BACKGROUND: Whilst modern awake intraoperative mapping has been widely accepted and implemented in the last decades in neuro-oncology, sparse reports have been published on the safety and efficiency of this approach in epilepsy surgery. METHOD: This article reports four cases with different locations of epileptogenic zones as examples of possible safe and efficient resections. RESULT: The results of the resections on seizure control were Engel 1 (no disabling seizures) in all cases and no patient experienced significant neurological deficits. DISCUSSION: The discussion focuses on aspects of the future of epilepsy surgery in a hodotopical paradigm.

Percutaneous coronary intervention in the very elderly with NSTE-ACS: the randomized 80+ study.

Objective: The treatment strategy in the very elderly with NSTE-ACS is debated, as they are often under-represented in clinical trials. The aim of this multicenter randomized controlled trial was to compare invasive and conservative strategies in the very elderly with NSTE-ACS.Methods: We randomly assigned patients ≥ 80 years of age with NSTE-ACS to an invasive strategy with coronary angiography and optimal medical treatment or a conservative strategy with only optimal medical treatment. The primary outcome was the combined endpoint of major adverse cardiac and cerebrovascular events (MACCE). Sample size was powered for a 50% reduction of event rate in MACCE with an invasive strategy. We used intention-to-treat analysis.Results: Altogether, 186 patients were included between 2009 and 2017. The study was terminated prematurely due to slow enrollment. At 12-month follow-up, the primary outcome occurred in 31 (33.3%) of the invasive treatment group and 34 (36.6%) of the conservative treatment group, with a hazard ratio (HR) of 0.90 (95% CI 0.55‒1.46; p = 0.66) for the invasive group relative to the conservative group. The corresponding HR value for urgent revascularization was 0.29 (95% CI 0.10‒0.85; p = 0.02), 0.56 (95% CI 0.27‒1.18; p = 0.13) for myocardial infarction, 0.70 (95% CI 0.31‒1.58; p = 0.40) for all-cause mortality, 1.35 (95% CI 0.23‒7.98; p = 0.74) for stroke, and 1.62 (95% CI 0.67‒3.90; p = 0.28) for recurrent hospitalization for cardiac reasons.Conclusion: In the very elderly with NSTE-ACS, we did not find any significant difference in MACCE between invasive and conservative treatment groups at 12-month follow-up, possibly due to small sample size.

Unrecorded Alcohol Consumption in Seven European Union Countries.

INTRODUCTION: Unrecorded alcohol, that is, alcohol not reflected in official statistics of the country where it is consumed, contributes markedly to overall consumption of alcohol. However, empirical data on unrecorded alcohol consumption are scarce, especially in high-income countries. This study measures the contribution of unrecorded alcohol in 7 member states of the European Union. METHODS: Two categories of unrecorded consumption were assessed in general population surveys (reducing alcohol related harm Standardized European Alcohol Survey; n = 11,224): home-made alcohol and cross-border shopping. Country-specific logistic regressions were used to link respondent characteristics to odds of acquisition of unrecorded alcohol. Total per capita alcohol consumption was estimated under different assumptions of calculating unrecorded alcohol consumption. RESULTS: Individuals with higher drinking levels were more likely to acquire unrecorded alcohol in all 7 countries. In some countries, male sex and more affluent social class were also positively linked to acquisition of unrecorded alcohol. There was a substantial contribution of unrecorded alcohol to overall consumption in 5 out of 7 member states (Croatia, Finland, Greece, Hungary, Portugal), but not in Poland or Spain. In Greece, up to two-thirds of all alcohol consumed was estimated to be unrecorded. CONCLUSION: Unrecorded alcohol contributes to overall consumption even in high-income countries, and thus needs to be monitored. In monitoring, as many categories of unrecorded alcohol as possible should be clearly defined (e.g., surrogate alcohol) and included in future surveys.

The association between duration of mechanical ventilation and survival in post cardiac arrest patients.

PURPOSE: To assess the association between the duration of mechanical ventilation during post resuscitation care and 30-day survival after cardiac arrest. METHODS: We conducted a retrospective observational study using data from two national registries. Comatose cardiac arrest patients admitted to general intensive care in Swedish hospitals between 2011 and 2016 were eligible. Based on the median duration of mechanical ventilation for patients who did not survive to hospital discharge, used as a proxy for the endurance of post resuscitation care, the hospitals were divided into four ordered groups for which association with 30-day survival was analyzed. RESULTS: In total, 5.113 patients in 56 hospitals were included. Median duration of mechanical ventilation for patients who did not survive to hospital discharge ranged from 17 h in hospital group 1-51 hours in hospital group 4. After adjustment for baseline characteristics, 30-day survival in the entire cohort was positively and independently associated with ordered hospital group: (adjusted odds ratio (95%CI); 1.12 (1.02,1.23); p = 0.02). Thus, hospitals with a longer duration of mechanical ventilation among non-survivors had better survival rate among patients admitted to ICU after a cardiac arrest. However, in a secondary analysis restricted to patients with length of stay in the intensive care unit ≥ 48 h, there was no significant association between 30-day survival and ordered hospital group. CONCLUSION: A tendency for longer duration of post resuscitation care in the ICU was associated with higher 30-day survival in comatose patients admitted to intensive care after cardiac arrest.

Comorbidity and bystander cardiopulmonary resuscitation in out-of-hospital cardiac arrest.

​OBJECTIVE: Cardiopulmonary resuscitation (CPR) performed before the arrival of emergency medical services (EMS) is associated with increased survival after out-of-hospital cardiac arrest (OHCA). The aim of this study was to determine whether patients who receive bystander CPR have a different comorbidity compared with patients who do not, and to determine the association between bystander CPR and 30-day survival when adjusting for such a possible difference. ​METHODS: Patients with witnessed OHCA in the Swedish Registry for Cardiopulmonary Resuscitation between 2011 and 2015 were included, and merged with the National Patient Registry. The Charlson Comorbidity Index (CCI) was used to measure comorbidity. Multiple logistic regression was used to examine the effect of CCI on the association between bystander CPR and outcome. ​RESULTS: In total, 11 955 patients with OHCA were included, 71% of whom received bystander CPR. Patients who received bystander CPR had somewhat lower comorbidity (CCI) than those who did not (mean±SD: 2.2±2.3 vs 2.5±2.4; p<0.0001). However, this difference in comorbidity had no influence on the association between bystander CPR and 30-day survival in a multivariable model including other possible confounders (OR 2.34 (95% CI 2.01 to 2.74) without adjustment for CCI and OR 2.32 (95% CI 1.98 to 2.71) with adjustment for CCI). ​CONCLUSION: Patients who undergo CPR before the arrival of EMS have a somewhat lower degree of comorbidity than those who do not. Taking this difference into account, bystander CPR is still associated with a marked increase in 30-day survival after OHCA.

Change and continuity in Finnish drinking in the 21st century.

Aim: Alcohol consumption and policy in Finland have undergone a variety of changes in the two last decades. In several cases, trends in both consumption and policy have shifted direction when moving from the first decade of the 21st century to the second one. The aim of the overview is to summarise the trends. Data: The overview draws on results primarily from the cross-sectional Finnish Drinking Habits Survey (FDHS) in 2000, 2008 and 2016, and also from the whole series including altogether seven separate data collections carried out every eight years from 1968 to 2016 and mainly covering Finns aged 15-69 years. Response rates show a falling trend (78% in 2000, 74% in 2008 and 60% in 2016). The overview also makes use of data collected within the European School Survey Project on Alcohol and other Drugs (ESPAD) and, for the elderly, the National FinSote study carried out by the Finnish Institute for Health and Welfare (THL). Results: After an all-time high of 12.7 litres of pure alcohol per capita 15 years and over in 2007, total consumption of alcohol had decreased by 21% by the year 2019. Underage drinking has decreased ever since the millennium shift. Older people's drinking has continued increasing or levelled out. Along with reduced total consumption, heavy episodic drinking (HED) has also decreased, but the differences between manual and white-collar workers in HED have continued to grow. Drinking alcoholic beverages with meals has also declined since 2008. Liberal and restrictive alcohol policy measures have alternated. Conclusions: Finnish drinking culture seems to change at a slow pace; several typical drinking habits have remained unchanged.
