One of the more relevant limitations that the illness trajectory concept has had on medical care utilization research on RA is that "the illness trajectory concept has the value of analytically ordering the events that occur over a sickness episode…but it cannot explain the link between such events" [ 21].
However, in long-term sickness absence, RTW trajectories in both health conditions become more similar because psychosocial factors rather than symptoms influence the RTW process.
Other common childhood sicknesses that followed this trajectory were mavabyi ya wheti (illness of the moon), xilala (head enlarging with depressed fontanel and body thinning) and xitsinana (measles).
This trajectory, soul-sickness, walking in nature, swimming, planting, observing, was the template for a gathering school of writers, many of them associated with the East Anglian countryside: WG Sebald, Ronald Blythe, Roger Deakin, Robert Macfarlane.
The data however suggest that not all childhood sickness was understood as following the same 'inherent' trajectory of xifuva.
This indicates the urgent need to gain knowledge about sickness absence and disability pension over the MS trajectory as well as to develop interventions aiming retaining PwMS in the work force.
Their model generates hundreds of estimates, creating visual "spaghetti," with some trajectories indicating a sharp rise in sickness and others a gradual uptick or downward trend.
Hence, baseline differences in risk profiles between high school dropouts and completers, to a large extent, may explain their further trajectories in adulthood and their risk for long-term sickness and disability [ 18, 19].
Mother of a 10-month-old boy As part of this trajectory, caretakers saw symptoms as an attack (ataque) of an inherent and permanent sickness, which was present whether or not the child had suffered from these symptoms before.
We excluded participants who retired because of longstanding illness or disability or through prolonged sickness absence (n=610) from the analytic sample, as previous research has found that health trajectories for these groups are very different from those of other retirees.
