Cancer related mortality in multiple sclerosis. A population based cohort study.

January 2023
Background: Cancer is a major cause of death, but how cancer influences mortality risk in Multiple Sclerosis (MS) is unclear.
Objectives: Determine all-cause mortality and mortality following a cancer diagnosis among MS patients compared with matched population controls.
Methods: Norwegian MS patients born 1930 - 1979 (n= 6950) followed-up 1953 - 2016, were matched with 37 922 controls.
Background: Whether disease-modifying therapies (DMTs) influence cancer in multiple sclerosis (MS) is uncertain.
Objectives: Assess incidence of cancer diagnosis among Norwegian MS patients compared to the general population in 1953 to 1995 and 1996 to 2017-reflecting era before and after introduction of DMTs.
Methods: We performed a nationwide cohort study comprising 6949 MS patients and 37,922 controls, matched on age, sex and county.
Background: Risk of cancer in multiple sclerosis (MS) patients compared to their siblings is unknown.
Objective: The objective was to prospectively investigate the risk of cancer among MS patients compared to siblings without MS and to population controls.
Methods: We retrieved data on MS patients born between 1930 and 1979 from the Norwegian Multiple Sclerosis Registry and population studies and on cancer diagnosis from the Cancer Registry of Norway.
Background Knowledge about long-term outcomes after medication withdrawal therapy for chronic headache, including tension type and migraine headache is lacking. Methods We re-examined 56 patients an average of nine years after they participated in a medication withdrawal study with a one-year follow-up. We collected and compared data on headache, use of medication, quality of life, quality of sleep, anxiety, depression, and labor participation one and nine years after the start of withdrawal therapy.

Objective: To examine the association between SES and MS risk during 50 years.
Methods: We included patients registered in Norwegian MS registries and prevalence studies born between 1930 and 1979, and identified their siblings and parents using the Norwegian Population Registry.
A remarkable increase in female to male ratio of multiple sclerosis (MS) is recognised in high incidence areas. Norway is a high-risk area for MS, spanning latitudes 58-71 °N. We studied whether the sex ratio has changed over time and whether it differs by clinical phenotype or by latitude.
View Article and Find Full Text PDFObjective: We aimed to determine if the risk of Multiple Sclerosis (MS) is associated with month of birth in Norway and to explore a possible latitudinal gradient.
Methods: All patients with MS born between 1930 and 1979 registered in the Norwegian MS Registry or ascertained in Norwegian prevalence studies were included (n = 6649). The latitude gradient was divided in Southern, Middle and Northern Norway, according to the estimated regional yearly mean vitamin D effective UV dose.
Objectives: To describe the functional level during sub-acute rehabilitation after moderate and severe traumatic brain injury (TBI) and to evaluate the impact of pre-injury and injury-related factors as predictors of early recovery.
Material And Methods: A prospective study of 55 patients with moderate (n = 21) and severe (n = 34) TBI who received specialized, inpatient rehabilitation. Functional level was assessed by the FIM.
