Preterm delivery and maternal obesity remain common complications in pregnancies with type 1 diabetes-A nationwide study in Sweden.

AIM: A primary goal of obstetric care of women with type 1 diabetes (T1D) is to reduce the risks of preterm birth (PTB). Besides hyperglycaemia, maternal obesity is an important risk factor for PTB in T1D. However, it's unclear if public health efforts decreased risks of maternal obesity and PTB in pregnancies with T1D. We examined time-trends over the last 20 years in the distribution of gestational ages at birth (GA) in offspring of women with T1D in Sweden, and in maternal BMI in the same mothers. METHODS: Population-based cohort study, using data from national registries in Sweden. To capture differences not only in the median values, we used quantile regression models to compare the whole distributions of GA's and early pregnancy BMI between deliveries in 1998-2007 (P1) and 2008-2016 (P2). Multivariable models were adjusted for differences in maternal age, smoking and education between periods 1 and 2. RESULTS: The study included 7639 offspring of women with T1D between 1998 and 2016. The 10% percentile GA, increased with 0.09 days (95% CI: -0.11 to 0.35) between P1 and P2. The 90% percentile for BMI was 1.20 kg/m2 higher (95% CI: 0.57 to 1.83) in P2. Risks of PTB remained stable over time also when adjusting for maternal BMI. CONCLUSION: Despite modern diabetes management, the distribution of GA, and consequently the risk of PTB in T1D, remained unchanged from 1998 to 2016. During the same time, maternal BMI increased, particularly in the already obese.

Learning curve in open groin hernia surgery: nationwide register-based study.

BACKGROUND: Current recommendations regarding the number of open groin hernia repairs that surgical trainees are required to perform during their residency are arbitrarily defined and vary between different curricula. This register-based study sought to investigate the learning curve of surgeons performing open anterior mesh repair for groin hernia by assessing hernia recurrence rates, surgical complications and operating times in relation to the number of procedures performed. METHOD: Nationwide data on open anterior mesh repair for groin hernia performed by surgical residents were collected from the Swedish Hernia Register between 2005 and 2020. The data were analysed in a cohort undergoing procedures carried out by surgeons performing their first registered repair as resident general surgeons. Repairs by surgeons with fewer than 30 repairs were excluded. RESULTS: A total of 38 845 repairs carried out by 663 surgeons were included. Operation time decreased with increasing number of performed procedures, mean (s.d.) operation time was 79 (26) min for the first 15 procedures and 60 (23) min after 241 procedures (P <0.001). A turning point where complication rates began to decrease was seen after 60 procedures. Complication rates were 3.6 per cent (396 of 10 978) for procedures 31-60 and 2.7 per cent (157 of 5 798) for procedures 61-120 (P = 0.002). There was no significant relationship between the number of procedures performed and the rate of operation on for recurrence (P = 0.894). CONCLUSION: Sixty performed procedures during surgical residency is a reasonable target for achieving competency to perform open anterior mesh repair for groin hernia safely without supervision.

Adjuvant use of melatonin for pain management in endometriosis-associated pelvic pain-A randomized double-blinded, placebo-controlled trial.

Considering the pharmacological treatment options for endometriosis-associated pain are confined to hormonal therapy and analgesics, we studied the analgesic effect of 20 mg melatonin as an adjuvant therapy in women with endometriosis-associated pain. This randomized double-blinded, placebo-controlled trial was conducted at the Research Center for Womens' Health at Södersjukhuset, a university hospital in Stockholm, Sweden. Forty women from 18 to 50 years of age with endometriosis and severe dysmenorrhea with or without chronic pelvic pain were given 20 mg Melatonin or placebo orally daily for two consecutive menstrual cycles or months. The level of pain was recorded daily on the 11-point numeric rating scale, a difference of 1.3 units was considered clinically significant. Clincaltrials.gov nr NCT03782740. Sixteen participants completed the study in the placebo group and 18 in the melatonin group. The difference in endometriosis-associated pain between the groups showed to be non-significant statistically as well as clinically, 2.9 (SD 1.9) in the melatonin group and 3.3 (SD 2.0) in the placebo group, p = 0.45. This randomized, double-blinded, placebo-controlled trial could not show that 20 mg of melatonin given orally at bedtime had better analgesic effect on endometriosis-associated pain compared with placebo. No adverse effects were observed.

Long-term neurological morbidity among children delivered by vacuum extraction - a national cohort study.

INTRODUCTION: This is the first nationwide cohort study of vacuum extraction (VE) and long-term neurological morbidity. We hypothesized that VE per se, and not only complicated labor, can cause intracranial bleedings, which could further cause neurological long-term morbidity. The aim of this study was to investigate the risk of neonatal mortality, cerebral palsy (CP), and epilepsy among children delivered by VE in a long-term perspective. MATERIAL AND METHODS: The study population included 1 509 589 term singleton children planned for vaginal birth in Sweden (January 1, 1999 to December 31, 2017). We investigated the risk of neonatal death (ND), CP, and epilepsy among children delivered by VE (successful or failed) and compared their risks with those born by spontaneous vaginal birth and emergency cesarean section (ECS). We used logistic regression to study the adjusted associations with each outcome. The follow-up time was from birth until December 31, 2019. RESULTS: The percentage and total number of children with the outcomes were ND (0.04%, n = 616), CP (0.12%, n = 1822), and epilepsy (0.74%, n = 11 190). Compared with children delivered by ECS, those born by VE had no increased risk of ND, but there was an increased risk for those born after failed VE (adj OR 2.23 [1.33-3.72]). The risk of CP was similar among children born by VE and those born spontaneously vaginally. Further, the risk of CP was similar among children born after failed VE compared with ECS. The risk of epilepsy was not increased among children born by VE (successful/failed), compared with those who had spontaneous vaginal birth or ECS. CONCLUSIONS: The outcomes ND, CP, and epilepsy are rare. In this nationwide cohort study, children born after successful VE had no increased risk of ND, CP or epilepsy compared with those delivered by ECS, but there was an increased risk of ND among those born by failed VE. Concerning the studied outcomes, VE appears to be a safe obstetric intervention; however, it requires a thorough risk assessment and awareness of when to convert to ECS.

Association between variables measured in the ambulance and in-hospital mortality among adult patients with and without infection: a prospective cohort study.

BACKGROUND: Patients presenting with infection to the ambulance are common, but risk factors for poor outcome are not known. The primary aim of the current study was to study the association between variables measured in the ambulance and mortality among adult patients with and without infection. The secondary aim was to study the association between these variables and mortality in a subgroup of patients who developed sepsis within 36 h. METHODS: Prospective cohort study of 553 ambulance patients with, and 318 patients without infection, performed in Stockholm during 2017-2018. The association between 21 variables (8 keywords related to medical history, 6 vital signs, 4 blood tests, and age, gender, comorbidity) and in-hospital mortality was analysed using logistic regression. RESULTS: Among patients with infection, inability of the patient to answer questions relating to certain symptoms such as pain and gastrointestinal symptoms was significantly associated with mortality in univariable analysis, in addition to oxygen saturation < 94%, heart rate > 110 /min, Glasgow Coma Scale (GCS) < 15, soluble urokinase Plasminogen Activator Receptor (suPAR) 4.0-7.9 ng/mL, suPAR ≥ 8.0 ng/mL and a Charlson comorbidity score ≥ 5. suPAR ≥ 8.0 ng/mL remained significant in multivariable analysis (OR 25.4; 95% CI, 3.2-199.8). Among patients without infection, suPAR ≥ 8.0 ng/mL and a Charlson comorbidity score ≥ 5 were significantly associated with mortality in univariable analysis, while suPAR ≥ 8.0 ng/mL remained significant in multivariable analysis (OR 56.1; 95% CI, 4.5-700.0). Among patients who developed sepsis, inability to answer questions relating to pain remained significant in multivariable analysis (OR 13.2; 95% CI, 2.2-78.9), in addition to suPAR ≥ 8.0 ng/mL (OR 16.1; 95% CI, 2.0-128.6). CONCLUSIONS: suPAR ≥ 8.0 ng/mL was associated with mortality in patients presenting to the ambulance both with and without infection and in those who developed sepsis. Furthermore, the inability of the ambulance patient with an infection to answer questions relating to specific symptoms was associated with a surprisingly high mortality. These results suggest that suPAR and medical history are valuable tools with which to identify patients at risk of poor outcome in the ambulance and could potentially signal the need of enhanced attention.

Keywords reflecting sepsis presentation based on mode of emergency department arrival: a retrospective cross-sectional study.

BACKGROUND: Current sepsis screening tools are predominantly based on vital signs. However, patients with serious infections frequently present with normal vital signs and there has been an increased interest to include other variables such as symptoms in screening tools to detect sepsis. The majority of patients with sepsis arrive to the emergency department by emergency medical services. Our hypothesis was that the presentation of sepsis, including symptoms, may differ between patients arriving to the emergency department by emergency medical services and patients arriving by other means. This information is of interest to adapt future sepsis screening tools to the population in which they will be implemented. The aim of the current study was to compare the prevalence of keywords reflecting the clinical presentation of sepsis based on mode of arrival among septic patients presenting to the emergency department. METHODS: Retrospective cross-sectional study of 479 adult septic patients. Keywords reflecting sepsis presentation upon emergency department arrival were quantified and analyzed based on mode of arrival, i.e., by emergency medical services or by other means. We adjusted for multiple comparisons by applying Bonferroni-adjusted significance levels for all comparisons. Adjustments for age, gender, and sepsis severity were performed by stratification. All patients were admitted to the emergency department of Södersjukhuset, Stockholm, and discharged with an ICD-10 code compatible with sepsis between January 1, and December 31, 2013. RESULTS: "Abnormal breathing" (51.8% vs 20.5%, p value < 0.001), "abnormal circulation" (38.4% vs 21.3%, p value < 0.001), "acute altered mental status" (31.1% vs 13.1%, p value < 0.001), and "decreased mobility" (26.1% vs 10.7%, p value < 0.001) were more common among patients arriving by emergency medical services, while "pain" (71.3% vs 40.1%, p value < 0.001) and "risk factors for sepsis" (50.8% vs 30.8%, p value < 0.001) were more common among patients arriving by other means. CONCLUSIONS: The distribution of most keywords related to sepsis presentation was similar irrespective of mode of arrival; however, some differences were present. This information may be useful in clinical decision tools or sepsis screening tools.

Performance of NEWS2, RETTS, clinical judgment and the Predict Sepsis screening tools with respect to identification of sepsis among ambulance patients with suspected infection: a prospective cohort study.

BACKGROUND: There is little evidence of which sepsis screening tool to use in the ambulance setting. The primary aim of the current study was to compare the performance of NEWS2 (National Early Warning score 2) and RETTS (Rapid Emergency Triage and Treatment System) with respect to identification of sepsis among ambulance patients with clinically suspected infection. The secondary aim was to compare the performance of the novel Predict Sepsis screening tools with that of NEWS2, RETTS and clinical judgment. METHODS: Prospective cohort study of 323 adult ambulance patients with clinically suspected infection, transported to hospitals in Stockholm, during 2017/2018. The sensitivity, specificity, and AUC (Area Under the receiver operating Curve) were calculated and compared by using McNemar´s test and DeLong's test. RESULTS: The prevalence of sepsis in the current study population was 44.6% (144 of 323 patients). No significant difference in AUC was demonstrated between NEWS2 ≥ 5 and RETTS ≥ orange. NEWS2 ≥ 7 demonstrated a significantly greater AUC than RETTS red. The Predict Sepsis screening tools ≥ 2 demonstrated the highest sensitivity (range 0.87-0.91), along with RETTS ≥ orange (0.83), but the lowest specificity (range 0.39-0.49). The AUC of NEWS2 (0.73) and the Predict Sepsis screening tools (range 0.75-0.77) was similar. CONCLUSIONS: The results indicate that NEWS2 could be the better alternative for sepsis identification in the ambulance, as compared to RETTS. The Predict Sepsis screening tools demonstrated a high sensitivity and AUCs similar to that of NEWS2. However, these results need to be interpreted with caution as the Predict Sepsis screening tools require external validation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03249597.

Protein profiles in plasma: Development from infancy to 5 years of age.

PURPOSE: Little is known about the longitudinal development of different plasma protein levels during early childhood and particularly in relation to lifestyle factors. This study aimed to monitor the plasma proteome early in life and the influence of different lifestyles. EXPERIMENTAL DESIGN: A multiplex bead-based immunoassay was used to analyze plasma levels of 97 proteins in 280 blood samples longitudinally collected in children at 6, 12, 24, and 60 months of age living in families with an anthroposophic (n = 15), partly anthroposophic (n = 27), or non-anthroposophic (n = 28) lifestyle. RESULTS: A total of 68 proteins (70%) showed significantly altered plasma levels between 6 months and 5 years of age. In lifestyle stratified analysis, 59 of 97 (61%) proteins were altered over time within one or more of the three lifestyle groups. Nearly half of these proteins (28 out of 59) changed irrespective of lifestyle. The temporal changes represented four longitudinal trends of the plasma proteins during development, also following stratification of lifestyle. CONCLUSIONS AND CLINICAL RELEVANCE: Our findings contribute to understand the development of the plasma proteome under the influence of lifestyle exposures in early childhood.

Myocardial Infarction in Systemic Lupus Erythematosus: Incidence and Coronary Angiography Findings.

An association between acute myocardial infarction (AMI) and systemic lupus erythematosus (SLE) has been suggested. The cause of AMI is presumed to be atherothrombosis. In the present study, the primary objective was to assess incident AMI cases and the secondary objective was to estimate the proportion of myocardial infarction with nonobstructive coronary arteries (MINOCA) in patients with SLE. All Swedish patients with SLE without AMI before 1996 (n = 4192) were followed for 20 years in the national patient registry. For each SLE patient, 10 age- and sex-matched controls without SLE and AMI before 1996 (n = 41 892) were identified. Data from patients and controls with AMI after 1996 were linked with the Swedish coronary angiography and angioplasty register; 549 (13%) and 3352 (8%) first AMIs occurred in patients with SLE and controls, respectively. The incidence of AMI was 9.6 (95% CI: 8.9-10.5) and 4.9 (95% CI: 4.8-5.1) events/1000 person-years in patients with SLE and controls, respectively. The proportion of MINOCA was 10.8% in patients with SLE and 13.8% in controls (P = .261), respectively. In conclusion, the incidence of AMI is increased in a European population of patients with SLE but there is no indication that the proportion of MINOCA is increased in these patients.

Surgical site infections after distal radius fracture surgery: a nation-wide cohort study of 31,807 adult patients.

BACKGROUND: Surgical site infections (SSI) after distal radius fracture (DRF) surgery have not previously been studied as the primary outcome in a large population with comparative data for different surgical methods. The aims of this study were 1) to compare SSI rates between plate fixation, percutaneous pinning and external fixation, and 2) to study factors associated with SSI. METHODS: We performed a nation-wide cohort study linking data from the Swedish national patient register (NPR) with the Swedish prescribed drug register (SPDR). We included all patients ≥18 years with a registration of a surgically treated DRF in the NPR between 2006 and 2013. The primary outcome was a registration in the SPDR of a dispensed prescription of peroral Flucloxacillin and/or Clindamycin within the first 8 weeks following surgery, which was used as a proxy for an SSI. The SSI rates for the three main surgical methods were calculated. Logistic regression was used to study the association between surgical method and the primary outcome, adjusted for potential confounders including age, sex, fracture type (closed/open), and a dispensed prescription of Flucloxacillin and/or Clindamycin 0-8 weeks prior to DRF surgery. A classification tree analysis was performed to study which factors were associated with SSI. RESULTS: A total of 31,807 patients with a surgically treated DRF were included. The proportion of patients with an SSI was 5% (n = 1110/21,348) among patients treated with plate fixation, 12% (n = 754/6198) among patients treated with percutaneous pinning, and 28% (n = 1180/4261) among patients treated with external fixation. After adjustment for potential confounders, the surgical method most strongly associated with SSI was external fixation (aOR 6.9 (95% CI 6.2-7.5, p < 0.001)), followed by percutaneous pinning (aOR 2.7 (95% CI 2.4-3.0, p < 0.001)) (reference: plate fixation). The classification tree analysis showed that surgical method, fracture type (closed/open), age and sex were factors associated with SSI. CONCLUSIONS: The SSI rate was highest after external fixation and lowest after plate fixation. The results may be useful for estimation of SSI burdens after DRF surgery on a population basis. For the physician, they may be useful for  estimating the likelihood of SSI in individual patients.

Dosing of thromboprophylaxis and mortality in critically ill COVID-19 patients.

BACKGROUND: A substantial proportion of critically ill COVID-19 patients develop thromboembolic complications, but it is unclear whether higher doses of thromboprophylaxis are associated with lower mortality rates. The purpose of the study was to evaluate the association between initial dosing strategy of thromboprophylaxis in critically ill COVID-19 patients and the risk of death, thromboembolism, and bleeding. METHOD: In this retrospective study, all critically ill COVID-19 patients admitted to two intensive care units in March and April 2020 were eligible. Patients were categorized into three groups according to initial daily dose of thromboprophylaxis: low (2500-4500 IU tinzaparin or 2500-5000 IU dalteparin), medium (> 4500 IU but < 175 IU/kilogram, kg, of body weight tinzaparin or > 5000 IU but < 200 IU/kg of body weight dalteparin), and high dose (≥ 175 IU/kg of body weight tinzaparin or ≥ 200 IU/kg of body weight dalteparin). Thromboprophylaxis dosage was based on local standardized recommendations, not on degree of critical illness or risk of thrombosis. Cox proportional hazards regression was used to estimate hazard ratios with corresponding 95% confidence intervals of death within 28 days from ICU admission. Multivariable models were adjusted for sex, age, body mass index, Simplified Acute Physiology Score III, invasive respiratory support, and initial dosing strategy of thromboprophylaxis. RESULTS: A total of 152 patients were included: 67 received low-, 48 medium-, and 37 high-dose thromboprophylaxis. Baseline characteristics did not differ between groups. For patients who received high-dose prophylaxis, mortality was lower (13.5%) compared to those who received medium dose (25.0%) or low dose (38.8%), p = 0.02. The hazard ratio of death was 0.33 (95% confidence intervals 0.13-0.87) among those who received high dose, and 0.88 (95% confidence intervals 0.43-1.83) among those who received medium dose, as compared to those who received low-dose thromboprophylaxis. There were fewer thromboembolic events in the high (2.7%) vs medium (18.8%) and low-dose thromboprophylaxis (17.9%) groups, p = 0.04. CONCLUSIONS: Among critically ill COVID-19 patients with respiratory failure, high-dose thromboprophylaxis was associated with a lower risk of death and a lower cumulative incidence of thromboembolic events compared with lower doses.

The predictive value of variables measurable in the ambulance and the development of the Predict Sepsis screening tools: a prospective cohort study.

BACKGROUND: Despite sepsis being a time critical condition with a high mortality, it is often not identified in a timely fashion. The aim of the current study was to create a screening tool based on bedside measurable variables predictive of sepsis among ambulance patients with infection according to clinical judgment by ambulance personnel. METHODS: Prospective cohort study of 551 adult patients presenting with suspected infection, performed in the ambulance setting of Stockholm during 2017-2018. 18 variables were measured in the ambulance (8 keywords related to medical history, 6 vital signs, 4 point-of-care blood tests, in addition to age, gender, and comorbidity. Logistic regression, area under the curve (AUC) and classification trees were used to study the association with sepsis. The AUC, sensitivity, specificity, predictive values and likelihood ratios were used to evaluate the predictive ability of sepsis screening models. RESULTS: The six variables with the strongest association with sepsis were: systolic blood pressure ≤ 100 mmHg, temperature > 38.5 °C, GCS < 15, lactate > 4 mmol/L, gastrointestinal symptoms, and a history of acute altered mental status. These were combined into the Predict Sepsis screening tool 1, with a sensitivity of 0.90, specificity 0.41, AUC 0.77; 95% confidence interval [CI] 0.73-0.81, PPV 0.52, and NPV 0.86. Combining a history of acute altered mental status with GCS < 15 and excluding lactate in the Predict Sepsis screening tool 2 did not noticeably affect the AUC. In addition, the AUCs of these models did not differ noticeably when compared to a model including vital signs alone, with novel calculated cut-offs; the Predict Sepsis screening tool 3. CONCLUSIONS: Systolic blood pressure ≤ 100 mmHg, temperature > 38.5 °C, GCS < 15, lactate > 4 mmol/L, gastrointestinal symptoms, and a history of acute altered mental status demonstrated the strongest association with sepsis. We present three screening tools to predict sepsis with similar sensitivity. The results indicated no noticeable increase of predictive ability by including symptom-variables and blood tests to a sepsis screening tool in the current study population. TRIAL REGISTRATION: NCT03249597.

The significance of cervical sagittal alignment for nonrecovery after whiplash injury.

BACKGROUND CONTEXT: Whiplash-associated disorder is a common cause of chronic neck pain. Several radiological cervical angular variables are suggested to have constitutional characteristics, that is, them being minimally influenced by body positioning. However, the association between these variables and pain conditions remains poorly understood. To our knowledge, no previous studies have investigated the association between constitutional angular variables and the outcome after whiplash trauma. PURPOSE: Our objectives were (1) to study the inter-rater agreement of sagittal radiologic variables between 2 raters and (2) to investigate any association between these variables and self-perceived nonrecovery after whiplash injury. STUDY DESIGN: Prospective cohort study. PATIENT SAMPLE: Forty-six patients aged 16 to 70 years, attending an emergency department after a motor vehicle accident resulting in neck pain were recruited. OUTCOME MEASURES: Self-perceived nonrecovery (yes/no) was the primary outcome measure. The secondary outcome measure was pain level on a numeric rating scale. METHODS: The participants underwent computed tomography scans in a supine position. Sagittal alignment variables (T1 slope, neck tilt, thoracic inlet angle [TIA], and C2-C7 angle) on the computed tomography scans were measured by 2 independent raters. Inter-rater agreement was tested with a paired sample t test and Bland-Altman plots for each variable. The patients were followed up after 6 months. RESULTS: No systematic differences for the assessed variables were found between the 2 raters. The overall nonrecovery rate was 28%. For the group with low neck tilt, the nonrecovery rate was 50% (95% CI: 36%-78%) and for the group with high neck tilt, 8% (95% CI: 3%-25%). The nonrecovery rate for the group low TIA was 50% (95% CI 29%-72%) and for those with high TIA 14% (95% CI 4%-26%). The associations remained significant after adjustments for possible confounders. The inter-rater analysis shows satisfactory agreement without proportional bias. CONCLUSIONS: This study indicates the existence of an association between the constitutional sagittal alignment of the cervical spine and the outcome after whiplash injuries.

Intervention with an educational video after a whiplash trauma - a randomised controlled clinical trial.

Background and aims Previous systematic reviews have considered that providing patient information is ineffective for patients with whiplash-associated disorders (WAD), with the exception of interventional educational videos. The aim of this randomised controlled clinical trial was to determine if use of an educational video as an intervention in the acute stage after a whiplash injury might improve self-reported recovery at 6 months after the injury. Methods In total, 289 consecutive patients with a whiplash injury following a motor vehicle collision were randomised to an intervention group (educational video) or to a control group (written information sheet). The video focused on information about pain mechanisms, deep flexor physiotherapy and reassurance. Emailed questionnaires were used to collect baseline data within 2 weeks after the accident and then to collect outcome data at 6 months post-injury. Non-responders were followed up with a brief telephone interview regarding the outcome. The primary outcome measure was self-reported recovery (yes/no) at 6 months post-injury. The secondary outcomes measures were pain level according to a numeric rating scale (NRS) and the whiplash disability questionnaire (WDQ) score at the same time point. Results The response rate for the baseline questionnaire was 70% (203/289). The follow-up rate was 97% (196/203). The non-recovery rates were similar between the intervention group, at 37.9% (39/103), and the control group, at 33.3% (31/93) (p = 0.55). No differences between the groups were noted in pain levels, NRS scores (1.9 vs. 2.2, p = 0.35) or the mean WDQ scores (17.5 vs. 21.2, p = 0.42). Conclusions The intervention with the educational video used in this study had no effect on the non-recovery rate when compared to a basic written information sheet. Implications The results of this trial add knowledge to the area of patient education for patients with acute WAD. Further studies are needed before the current recommendations for patient information are modified.

Factors related to the role of programme directors in association with quality in postgraduate medical education - a cross-sectional study.

BACKGROUND: Educational leaders have been pointed out as being important for quality of medical education. However, their actual influence on the education can be limited. At the postgraduate level, educational leadership and its connection with quality is underexplored and knowledge about how to increase its impact is lacking. An increased understanding could be used in order to prioritize actions for strengthening the role. The aim of this study was to investigate factors related to the role of programme director associated with quality in postgraduate medical education. METHODS: A cross-sectional study was carried out. A questionnaire was sent to programme directors in Sweden (n = 519) comprising questions about background factors, work characteristics, work tasks, hindering and enabling factors, and the Utrecht Work Engagement Scale. A logistic regression and classification tree were used to identify factors associated with high qualitative education, defined as compliance with national regulations. RESULTS: The response rate was 54% (n = 279). In total, 62% of the programme directors reported high quality and factors associated with high quality included experiences of communication with residents, superiors and supervisors, and support from the supervisors. Other factors were consensus regarding postgraduate medical education at the workplace, adequate financial resources, the programme directors' competence, and their perceived impact on education. Factors of particular importance seemed to differ depending on whether the programme directors were responsible for one or for multiple units. Most high-quality education was found in cases where programme directors were responsible for a single unit and perceived sufficient impact on education. CONCLUSIONS: These results indicated that there was an association between factors related to programme director and quality in postgraduate medical education. The findings pointed out the importance of combining activities at both individual, group and organizational levels. Relational aspects should not be underestimated; faculty development and involvement are crucial.

Association between cervical degeneration and self-perceived nonrecovery after whiplash injury.

BACKGROUND CONTEXT: Pre-existing radiological degenerative changes have not previously been considered a risk factor for nonrecovery from neck pain due to motor vehicle accidents (MVA). Results from previous studies are however often based on assessment of plain radiography or MRI and little consideration has been given to facet joints. Furthermore, previous studies have often lacked a validated scoring system for degenerative changes. PURPOSE: To investigate the association between cervical degeneration on computed tomography (CT) and nonrecovery after whiplash trauma. STUDY DESIGN: Longitudinal cohort study. PATIENT SAMPLE: One hundred twenty-one patients attending the Emergency Department because of neck pain after MVA, 2015-2017, with a valid CT-scan of the cervical spine and completion of follow up after 6 months. OUTCOME MEASURES: The primary outcome measure was self-perceived nonrecovery (yes/no) after 6 months. A secondary outcome measure was self-reported pain level (Numeric Rating Scale). METHODS: Baseline data regarding demographics and health factors were gathered through a web-based questionnaire. Degeneration of facet joints and intervertebral discs was assessed on CT-scans according to a validated scoring system. Binary logistic regression was used to study the association between cervical degeneration and nonrecovery. RESULTS: Moderate facet joint degeneration was associated with nonrecovery. In the group with moderate degree of facet joint degeneration, 69.6% reported nonrecovery compared with 23.6% among patients without any signs of degeneration (adjusted odds ratio 6.7 [95% confidence interval: 1.9-24.3]). There was no association between disc degeneration and nonrecovery. Combined facet joint degeneration and disc degeneration were associated with nonrecovery (adjusted odds ratio 6.2 [2.0-19.0]). CONCLUSIONS: These results suggest that cervical degeneration, especially facet joint degeneration, is a risk factor for nonrecovery after whiplash trauma. We hypothesize that whiplash trauma can be a trigger for painful manifestation of previously asymptomatic facet joint degeneration.

Swedish doctors choice of medical speciality and associations with cultural capital and perceived status: a cross-sectional study.

BACKGROUND: Many western countries have problems recruiting and retaining medical specialists. In Sweden there is a lack of primary care doctors and psychiatrists. Despite much research on the topic the shortage remains. We therefore set out to analyse choice of medical speciality using Bourdieu's theoretical concepts; cultural capital, social background and perceived status. METHODS: A cross-sectional questionnaire-based study of 399 alumni from the Medical School at Karolinska Institutet, Stockholm was performed. The response rate was 72% (n = 286); 262 of the respondents were in training to become specialists. Specialties were categorized as primary care, psychiatry, internal medicine, and surgical and hospital service specialties. To study the associations between medical specialties and cultural capital, we used multinomial regression analyses. Variables that showed a significant association with medical specialties were included in an adjusted multivariable model. These results were presented as odds ratios: the odds that a particular speciality is chosen in comparison to a choice of surgery as a speciality, based on perceptions of high status. RESULTS: The results were analysed using Bourdieu's theoretical concepts of cultural capital, in the form of educational capital and social prestige. We found distinctive differences in perceived status for the examined speciality groups, ranging from 70% high status for surgery down to 6% high status for geriatrics and primary care. Perceived status was also associated with respondents' own speciality choice, presented as an odds ratio. Our data did not show any associations between speciality choice and educational capital. We also included sociodemographic data. CONCLUSION: The field of medicine is according to Bourdieu an arena for power struggles. Knowledge of the distinctive differences in perceived status between medical specialties can be an asset particularly in relation to recruitment and retainment of specialist doctors. Our results could be used to identify specialities where perceptions of low status may be contributing to a shortage of specialists.

Quantifying cervical spondylosis: reliability testing of a coherent CT-based scoring system.

BACKGROUND: Grading of degeneration of the cervical spine is of great clinical value, considering the vast amount of radiological investigations that are being done with this query. Despite the fact that Computed Tomography (CT) is frequently used in clinical practice there is today no user-friendly and reliable scoring system for assessment of cervical spondylosis on CT-scans available. The aim of this study was to establish a scoring system for cervical spondylosis based on CT-scans and to test it for reliability. METHODS: Twenty adult patients undergoing CT of the cervical spine due to neck pain following a motor vehicle accident were included in the study. Three independent raters, i.e. one orthopedic surgeon and two radiologists, assessed their CT-scans. Two of the raters repeated the assessments after three months. A radiographic-based scoring system for cervical disc degeneration, addressing disc height, osteophytes and endplate sclerosis, was applied on CT and tested for reliability. A pre-existing, reliable CT-based scoring system for facet joint degeneration, considering joint space narrowing, osteophytes and irregularity of the articular surface was modified and reevaluated. This in order to develop a coherent CT-based total degeneration score for cervical spondylosis. RESULTS: The scoring systems for cervical disc degeneration and facet joint degeneration both exhibited an acceptable or better level of strength of agreement regarding intra- and interrater agreement. The total disc degeneration score showed a moderate level of inter-rater reliability with a kappa-value of 0.47 and a good intra-rater agreement with intra-class correlation coefficients (ICC) of 0.67 and 0.60 for the two raters performing the assessments. The total facet joint degeneration score showed a moderate level of inter-rater reliability (kappa 0.54) and an excellent intra-rater agreement with ICC 0.75 for one of the raters and fair for the other rater (ICC 0.54). When the total disc and facet joint degeneration score were classified into a three-point total degeneration score the inter-rater agreement was 0.695 and the ICC 0.82 and 0.73 respectively. CONCLUSIONS: This coherent scoring system assessing both disc degeneration and facet joint degeneration on CT-scans of the cervical spine was shown to meet the standards of reliability.

Stress among medical students during clinical courses: a longitudinal study using contextual activity sampling system.

OBJECTIVES: To investigate medical students' experiences of stress and other emotions related to their professional roles, as defined by the CanMEDS framework, by using the Contextual Activity Sampling System (CASS). METHODS: Ninety-eight medical students agreed to participate of whom 74 completed this longitudinal cohort study. Data was collected between 6th and 8th term via CASS methodology: A questionnaire was e-mailed to the participants every 3rd week(21questionnaires/measurements) during clinical rotations and scientific project work term. Emotions were measured by a 7-point Likert scale (e.g., maximum stress = 7). Answers were registered through mobile technology. We used a linear mixed-model regression approach to study the association between stress over time in relation to socio-demographic and learning activities related to CanMEDS roles. RESULTS: Participants completed 1390 questionnaires. Mean stress level over all time points was 3.6. Stress was reported as highest during the scientific project term. Learning activities related to 'Communicator,' 'Collaborator,' 'Scholar,' 'Manager' and 'Professional' were associated with increased stress, e.g. 'Scholar' increased stress with 0.5 points (t(1339)=3.91, p<0.001). A reduced level of stress was associated with 'Health Advocate' of 0.39 points (t(1338)=-2.15, p=0.03). No association between perceived stress and demographic factors, such as gender or age was found. CONCLUSIONS: An association between different learning activities related to CanMEDS Roles and feelings of stress were noted. The CASS methodology was found to be useful when observing learning experiences and might support educational development by identifying course activities linked to stress.

Is tramadol associated to bleeding peptic ulcer? A nationwide case-control study in hospitalized Swedish patients.

AIMS: Tramadol, a widely used analgesic drug, inhibits the reuptake of noradrenaline and serotonin impairing the aggregation function of thrombocytes. However, the risk for severe bleeding has previously not been studied. The aim of the present study is to investigate the association between tramadol and bleeding peptic ulcer in the Swedish population. METHODS: In this register based case-control study based on the Swedish national patient registry and prescription drug registry, we included 18 306 patients hospitalized with a first-time diagnosis of bleeding peptic ulcer. For every case, 4 matched controls were included. To investigate the temporal aspects of tramadol induced bleeding ulcer, exposure was divided into patients with newly initiated and ongoing treatment. To explore a possible confounding by indication, the effect of codeine, a drug also prescribed for the treatment of moderate pain, but not known to affect thrombocyte function, was investigated. Univariable and multivariable logistic regression was used to analyse the association between tramadol use and bleeding ulcer. RESULTS: Tramadol was associated with an increased risk of bleeding ulcer (adjusted odds ratio (aOR) 2.1, 95% confidence interval: (2.0-2.3). The association was stronger for newly initiated treatment with tramadol 2.8 (2.5-3.2) and weaker for ongoing treatment 1.7 (1.6-1.9). Codeine was also associated with an increased risk of bleeding ulcer 1.9 (1.7-2.1) and this association was also stronger for newly initiated treatment with codeine 2.3 (2.0-2.6) and weaker for ongoing treatment 1.7 (1.5-1.9). CONCLUSION: Treatment with tramadol was associated with an increased risk of bleeding peptic ulcer. Most of this association may be mediated by factors related to the pain condition rather than the pharmacologic effect per se.
