Effect of physical activity and vitamin D compared with vitamin D alone on muscle strength, back flexibility and aerobic activity in patients with chronic kidney disease: A comparative study from Pakistan.

BACKGROUND AND OBJECTIVES: To compare the differences in musculoskeletal health with vitamin D alone in comparison with vitamin D with physical activity (PA) among chronic kidney disease (CKD) patients. METHODS AND STUDY DESIGN: An open labeled, randomized, controlled trial was conducted at two tertiary care centers in Pakistan. Patients with CKD stage 2-4 and vitamin D deficiency (<20 ng/mL) were recruited in the trial. Both the arms were given oral vitamin D (cholecalciferol) drops (4000 IU) once daily for three months. One arm received only vitamin D (VD arm), while the second arm received vitamin D along with PA (VDPA arm). RESULTS: Of the 1,235 CKD stage 2-4 subjects contacted, forty-six subjects were enrolled. Eighteen were assigned to VD arm and twenty-eight were assigned to VDPA arm. Between groups comparison shows that bicep strength increases from 15 to 17 kg. Likewise, back flexibility and aerobic fitness also increased among those who receive vitamin D and physical activity, however these differences were not statistically significant (p>0.05). Sensitivity analysis within group comparison shows rise of bicep strength from 13.8 kg to 15.2 kg in the VD alone arm (p=0.05); however, in the VDPA arm, there is a greater difference of 14.3 kg to 17.2 kg (p<0.001). CONCLUSIONS: Targeted PA among CKD patients has potential to improve bicep strength and back flexibility. However, as the sample size was small, further studies would be required to suggest whether a PA should be included as part of the treatment regimen.

The management and clinical knowledge of headache disorders among general practitioners in Norway: a questionnaire survey.

BACKGROUND: General practitioners (GPs) diagnose and manage a majority of headache patients seeking health care. With the aim to understand the potential for clinical improvement and educational needs, we performed a study to investigate Norwegian GPs knowledge about headache and its clinical management. METHODS: We invited GPs from a random sample of 130 Norwegian continuous medical education (CME) groups to respond to an anonymous questionnaire survey. RESULTS: 367 GPs responded to the survey (73% of invited CME groups, 7.6% of all GPs in Norway). Mean age was 46 (SD 11) years, with an average of 18 (SD 10) years of clinical experience. In general the national treatment recommendations were followed, while the International Classification of Headache Disorders and other international guidelines were rarely used. Overall, 80% (n = 292) of the GPs suggested adequate prophylactic medication for frequent episodic migraine, while 28% (n = 101) suggested adequate prophylactic medication for chronic tension-type headache (CTTH). Half (52%, n = 191)) of the respondents were aware that different types of acute headache medication can lead to medication-overuse headache (MOH), and 59% (n = 217) knew that prophylactic headache medication does not lead to MOH. GPs often used MRI in the diagnostic work-up. GPs reported that lack of good treatment options was a main barrier to more optimized treatment of headache patients. CONCLUSION: The knowledge of management of CTTH and MOH was moderate compared to migraine among Norwegian GPs.

Stroke Mimics on the Stroke Unit - Temporal trends 2008-2017 at a large Norwegian university hospital.

OBJECTIVES: The objective was to quantify temporal trends in stroke mimics (SM) admissions relative to cerebrovascular accidents (CVA), incidence of hospitalized SMs and characterize the SM case-mix at a general hospital's stroke unit (SU). MATERIALS & METHODS: All SU admissions (n = 11240) of patients aged 15 or older to Haukeland University Hospital between 2008-2017 were prospectively included and categorized as CVA or SM. Logistic regression was used to estimate time trends in the proportion of SMs among the admissions. Poisson regression was used to estimate time trends in age- and sex-dependent SM incidence. RESULTS: SMs were on average younger thaan CVA patients (68.3 vs. 71.4 years) and had a higher proportion of females (53.6% vs. 44.5%). The total proportion of SM admissions was 51.0%. There was an increasing time trend in the proportion of SM admissions, odds ratio 1.150 per year (p < 0.001), but this trend appears flattening, represented by a significant quadratic time-term, odds ratio 1.009 (p < 0.001). A higher SM proportion was also associated with the time period of a Mass Media Intervention (FAST campaign) in 2014. There was also an increasing trend in SM incidence, that remains after adjusting for age, sex, and population; also, for incidence the trend appears to be flattening. CONCLUSIONS: SMs account for approximately half of the SU admissions, and the proportion has been increasing. A FAST campaign appears to have temporarily increased the SM proportion. The age- and sex-dependent incidence of SM has been increasing but appears to flatten out.

Experiences, distress and burden among neurologists in Norway during the COVID-19 pandemic.

BACKGROUND: The ongoing COVID-19 pandemic has caused rapid changes in the healthcare system. Workforce reorganization, reduced standard of care and a lack of personal protection equipment (PPE) for health care workers were among the concerns raised in the first wave of the pandemic. Our aim was to explore the experiences, distress and burden among Norwegian neurologists during the first weeks of the pandemic. METHODS: Hospital-based neurologists in Norway (n = 400) were invited to a web-based survey in April 2020. The study focused on patient management, organizational changes and personal stress during the first weeks of the pandemic lockdown. Work-home interface stress was assessed by the Cooper Job Stress Questionnaire. RESULTS: In total, 135 neurologists participated. Seventy-three% experienced a change in their personal work situation, and 67% examined patients with suspected COVID-19 infection and neurological disease. Changed access to resources, and the perception that medical follow-up was unsatisfactory, were associated with a high degree of burden and stress. Neurologists were also worried about the potential lack of PPE and the fear of spreading SARS CoV-2 to close family members. The mean score of work-home interface stress was 2.8 with no significant differences between gender or specialist status. Reduced standard of care was reported for all neurological conditions, and in particular for non-emergency treatments. CONCLUSION: The vast majority of neurologists in Norway experienced a change in their personal work situation during the first phase of the pandemic. The fear of becoming infected and ill was not a major contributor to burden and stress.

Stroke admission rates before, during and after the first phase of the COVID-19 pandemic.

BACKGROUND: There was a significant decrease in stroke admissions during the first phase of the COVID-19 pandemic. There are concerns that stroke patients have not sought medical attention and in the months after the lockdown suffer recurrent severe strokes. The aims of this study were to investigate how stroke admission rates and distributions of severity varied before, during and after the lockdown in a representative Norwegian hospital population. METHODS: All patients discharged from Akershus University Hospital with a diagnosis of transient ischemic attack (TIA) or acute stroke from January to September 2020 were identified by hospital chart review. RESULTS: We observed a transient decrease in weekly stroke admissions during lockdown from an average of 21.4 (SD 4.7) before to 15.0 (SD 4.2) during and 17.2 (SD 3.3) after (p < 0.011). The proportion of mild ischemic and haemorrhagic strokes was also lower during lockdown with 66% before, 57% during and 68% after (p = 0.011). CONCLUSION: The period of COVID-19 lockdown was associated with a temporary reduction in total admissions of strokes. In particular, there were fewer with TIA and mild stroke. Given the need to prevent the worsening of symptoms and risk of recurrence, it is necessary to emphasise the importance to seek medical care even in states of emergency.

Acute stroke care during the first phase of COVID-19 pandemic in Norway.

OBJECTIVES: The aim of the present study was to investigate how the initial phase of the COVID-19 pandemic affected the hospital stroke management and research in Norway. MATERIALS AND METHODS: All neurological departments with a Stroke Unit in Norway (n = 17) were invited to participate in a questionnaire survey. The study focused on the first lockdown period, and all questions were thus answered in regard to the period between 12 March and 15 April 2020. RESULTS: The responder rate was 94% (16/17). Eighty-one % (13/16) reported that the pandemic affected their department, and 63% (10/16) changed their stroke care pathways. The number of new acute admissions in terms of both strokes and stroke mimics decreased at all 16 departments. Fewer patients received thrombolysis and endovascular treatment, and multidisciplinary stroke rehabilitation services were less available. The mandatory 3 months of follow-up of stroke patients was postponed at 73% of the hospitals. All departments conducting stroke research reported a stop in ongoing projects. CONCLUSION: In Norway, hospital-based stroke care and research were impacted during the initial phase of the COVID-19 pandemic, with likely repercussions for patient care and outcomes. In the future, stroke departments will require contingency plans in order to protect the entire stroke treatment chain.

Experiences of telemedicine in neurological out-patient clinics during the COVID-19 pandemic.

OBJECTIVE: The COVID-19 pandemic has led to rapid changes in the delivery of medical care worldwide. The main objective of this survey was to investigate the initial experiences of neurologists with the use of telemedicine for different neurological conditions during the first phase of the COVID-19. METHODS: All hospital-based neurologists in Norway (n = 400) were invited to a questionnaire survey by e-mail in April 2020. The study focused on telemedicine and all questions were answered with regard to the first weeks of the pandemic lockdown in Norway. RESULTS: One-hundred and thirty-five neurologists responded. Overall, 87% reported a shift toward more telemedicine, with significantly more use of telephone than video consultations for both new referrals (54% vs. 30%, P < 0.001) and follow-ups (99% vs. 50%, P < 0.001). Respondents deemed it much more professionally satisfactory to conduct follow-up consultations by telephone, than to carry out consultations with new patients by telephone (85% vs. 13%, P < 0.001). Teleconsultations were better suited for headache and epilepsy patients as compared to multiple sclerosis and movement disorder patients. There was no significant difference between residents and senior consultants regarding how they experienced teleconsultations. Female neurologists found telemedicine better and more effective than male neurologists. INTERPRETATION: Telemedicine was rapidly implemented in Norwegian neurological departments during the first weeks of the COVID-19 pandemic. Teleconsultations were better suited for follow-ups than for new referrals, and better for headache and epilepsy patients as compared to multiple sclerosis and movement disorder patients.

Hospital-based headache care during the Covid-19 pandemic in Denmark and Norway.

BACKGROUND: The Covid-19 pandemic is causing changes in delivery of medical care worldwide. It is not known how the management of headache patients was affected by the lockdown during the pandemic. The aim of the present study was to investigate how the initial phase of the Covid-19 pandemic affected the hospital management of headache in Denmark and Norway. METHODS: All neurological departments in Denmark (n = 14) and Norway (n = 18) were invited to a questionnaire survey. The study focused on the lockdown and all questions were answered in regard to the period between March 12th and April 15th, 2020. RESULTS: The responder rate was 91% (29/32). Of the neurological departments 86% changed their headache practice during the lockdown. The most common change was a shift to more telephone consultations (86%). Video consultations were offered by 45%. The number of new headache referrals decreased. Only 36% administered botulinum toxin A treatment according to usual schemes. Sixty% reported that fewer patients were admitted for in-hospital emergency diagnostics and treatment. Among departments conducting headache research 57% had to halt ongoing projects. Overall, 54% reported that the standard of care was worse for headache patients during the pandemic. CONCLUSION: Hospital-based headache care and research was impacted in Denmark and Norway during the initial phase of the Covid-19-pandemic.

Incidence and Mortality of Cerebral Venous Thrombosis in a Norwegian Population.

BACKGROUND AND PURPOSE: There are conflicting figures of the incidence of cerebral venous thrombosis (CVT). The incidence was previously estimated to around 0.5/100 000/y, but more recent studies have suggested 1 to 1.5/100 000/y. The purpose of this study was to explore the incidence and mortality of CVT in a Norwegian population. METHODS: A retrospective cross-sectional hospital population-based study conducted at Akershus University Hospital serving roughly 10% of the total Norwegian population. Patients were identified through chart reviews based on the relevant International Classification of Diseases(Tenth Revision) codes for new CVT cases in a 7-year period between January 1, 2011, and December 31, 2017. Only inhabitants living in the hospital's catchment area were included. RESULTS: Sixty-two patients aged 0 to 80 years were identified and included. The median age was 46 years and 53% were females. The overall incidence of CVT was 1.75 (95% CI, 1.36-2.23) per 100 000/y with no significant sex differences. The incidence for children and adolescents (<18 years, n=9) was lower than for adults (≥18 years, n=53); 1.08 (0.52-1.97) versus 1.96 (1.49-2.55) per 100 000/y per year, with the highest incidence for those >50 years with 2.10 (1.38-3.07)/100 000/y. Headache was the most prevalent symptom, reported in 83%, followed by nausea, motor deficits, and seizures observed in 45%, 32%, and 32% of the patients. Transverse sinuses and the jugular vein were the most frequent sites of thrombosis. In most patients (61%), thrombosis occurred in multiple sinuses/veins. Risk factors were found in 73% of the patients, and most of the patients had a combination of 2 or more risk factors. The 30-day and 1-year mortality rates were 3% and 6%. CONCLUSIONS: The incidence of CVT in this population was higher than previously reported. The mortality rate was similar to previous studies.

Fewer ischemic strokes, despite an ageing population: stroke models from observed incidence in Norway 2010-2015.

BACKGROUND: Stroke incidence rates have fallen in high-income countries over the last several decades, but findings regarding the trend over recent years have been mixed. The aim of the study was to describe and model temporal trends in incidence of stroke by age and sex between 2010 and 2015 in Norway, and to generate incidence projections towards year 2040. METHODS: All recorded strokes in Norway between 2010 and 2015 were extracted from the National Patient Registry and the National Cause of Death Registry. We report incidence by age, sex, and year; in raw numbers, per 100,000 person-years, by WHO and European standard populations; and generated statistical models by stroke type, age, sex, and year; and projected stroke incidence toward year 2040. RESULTS: The data covered 30.1 million person-years at risk, 53431 unique individuals hospitalized with a primary stroke diagnosis, and 6315 additional individuals registered as dead due to stroke. From 2010 to 2015, individuals suffering stroke per 100,000 person-years dropped from 239 to 195 (208 to 177 excluding immediate deaths). The decline was driven by ischemic strokes, with a statistically non-significant time trend for hemorrhagic stroke. CONCLUSIONS: The age-dependent incidence of ischemic strokes in Norway is declining rapidly, and more than compensates for the growth and ageing of the population. Comparisons with historic incidence statistics show that the reduction in incidence rates has accelerated over the last two decades.

Stroke-Related Knowledge and Lifestyle Behavior among Stroke Survivors.

AIMS: Awareness of stroke symptoms and risk factors, and actions taken in order to reduce the risk of new stroke events, should be of great importance among stroke survivors. The aims of this study were to assess changes in stroke-related knowledge and lifestyle behavior among patients experiencing a cerebrovascular event, and to assess the agreement between the patients' self-reported diagnosis, and the discharge diagnosis. METHODS: All patients discharged with a diagnosis of stroke or transient ischemic attack during a 1-year period, received postal survey questionnaires at 3 and 12 months after discharge. The questionnaires included questions about symptom knowledge, lifestyle behavior, and patients were asked to report on their diagnosis. RESULTS: A total of 282 patients were included (mean age 71.8 years, 57.1% men). Self-reported symptom knowledge was increased at 3 months (P < .001), and this persisted at 12 months. There was a poor correlation (r = .082; P = .171) between increasing symptom knowledge and stated lifestyle behavior changes. In all, 63% of the respondents correctly identified their own cerebrovascular subtype. Thirty-seven percent had quit smoking after 12 months, 30% reported that they used less sugary items, and 26% used less fatty food after the cerebrovascular event. CONCLUSIONS: Stroke survivors reported increased stroke symptoms knowledge after 3 and 12 months. A proportion of patients made changes in lifestyle behavior. Only 2 out of 3 patients correctly identified their own cerebrovascular subtype, indicating room for improvement in clinical practice when informing and communicating with stroke and transient ischemic attack patients about their diagnosis.

Emergency department crowding and length of stay before and after an increased catchment area.

BACKGROUND: Emergency department (ED) crowding and prolonged length of stay (LOS) are associated with delays in treatment, adverse outcomes and decreased patient satisfaction. Hospital restructuring and mergers are often associated with increased ED crowding. The aim of this study was to explore ED crowding and LOS in Norway's largest ED before and after an increased catchment area. METHODS: The catchment area of Akershus University Hospital increased by approximately 150,000 inhabitants in 2011, from 340,000 to 490,000. In this retrospective study, admissions to the ED during a six-year period, from Jan 1st 2010 to Dec 31st 2015 were included and analyzed. RESULTS: A total of 179,989 admissions were included (51.0% men). The highest occupancy rate was in the age group 70-79 years. Following the increase in the catchment area, the annual ED admissions increased by 8343 (40.9%) from 2010 to 2011, and peaked in 2013 (34,002). Mean LOS increased from 3:59 h in 2010 to 4:17 in 2012 (highest), and decreased to 3:45 h in 2015 after staff, capacity and organizational measures. In 2010, 37.9% of the ED patients experienced crowding, and this proportion increased to between 52.9-77.6% in 2011-2015. Crowding peaked between 4 and 5 PM. CONCLUSIONS: LOS increased and crowding was more frequent after a major increase in the hospital's catchment area in Norway's largest emergency department. Even after 5 years, the LOS was higher than before the expansion, mainly because of the throughput and output components, which were not properly adapted to the changes in input.

Neurology residents' knowledge of the management of headache.

BACKGROUND: In Norway, as in most other countries, the training program for clinical neurology has no mandatory headache program. Knowledge in headache management must therefore be acquired during everyday clinical training. The objectives of this study were to investigate neurology residents' knowledge of headache. METHODS: A questionnaire survey was undertaken among neurology residents in Norway. RESULTS: All 17 neurological departments in Norway participated, and 143 residents responded (86%). Sixty percent were women, mean age was 32.5 years, and the respondents had an average of 28 months clinical training in neurology. Fifty-six percent knew the approximate prevalence of migraine and chronic headache. Thirty-seven percent asked their patients about disability, quality of life, and social functioning at every consultation. Further, 72% would prescribe prophylaxis for chronic tension-type headache and 97% for very frequent migraine. One third wrongly stated that use of the most common headache prophylactics could lead to medication-overuse headache. Headache diaries were used regularly by 63% for diagnostic purposes, and 73% requested an MRI for all long-lasting headaches referred to neurological outpatient clinics. CONCLUSION: Although a major public health problem, headache knowledge is moderate at best, and its management clearly varies. There is an unmet need for a better and more structured headache training program in Norway.

Prestige of neurological disorders among future neurologists in Norway.

BACKGROUND: Neurology has increasing subspecialization. Some disorders, such as cerebrovascular diseases, dementia and headache, are highly prevalent in the general population, while others, such as movement disorders and multiple sclerosis, are rarer. Thus, there may be a mismatch between neurologists' interests and the population needs. AIMS OF THE STUDY: To investigate the perceived prestige of neurological disorders among residents in neurology. METHODS: The study was conducted as a questionnaire survey among residents in neurology in Norway. RESULTS: All the 17 neurological departments in Norway participated. In total, 143 residents participated (86% response rate). Mean age was 32.5 years. The respondents had on average 28 months of clinical training in neurology. The subspecialty with the highest prestige was cerebrovascular diseases, scored by 62% as the most prestigious, followed by multiple sclerosis (36%) and epilepsy (7%). The subspecialties with the lowest prestige were headache (2.8%) and dementia (1.4%). None of the tested variables (gender, age, months in clinical training or type of hospital) were associated with the perceived prestige of neurological disorders. CONCLUSION: Cerebrovascular disease was perceived as the most prestigious subspecialty. Headache and dementia, which are major contributors to worldwide disability, have low status among residents in neurology.
