Abstract [en]

Objective The objective was to investigate 10-year mortality, causes of death and cardiovascular comorbidity in idiopathic normal pressure hydrocephalus (iNPH) and to evaluate their mutual associations.Methods This prospective cohort study included 176 CSF-shunted iNPH patients, and 368 age- and sex-matched controls. At inclusion, participants were medically examined, had blood analyzed and answered a questionnaire. The vascular comorbidities investigated were smoking, diabetes, body mass index, blood pressure (BP), hyperlipidemia, kidney function, atrial fibrillation and, cerebro- and cardiovascular disease.Results Survival was observed for a mean period of 10.3 +/- 0.84 years. Shunted iNPH patients had an increased risk of death compared to controls (hazard ratio (HR) = 2.5, 95% CI 1.86-3.36; p < 0.001). After 10 years, 50% (n = 88) of iNPH patients and 24% (n = 88) of the controls were dead (p < 0.001). The risk of dying from cardiovascular disease, falls and neurological diseases were higher in iNPH (p < 0.05). The most common cause of death in iNPH was cardiovascular diseases (14% vs 7% for controls). Seven out of nine iNPH dying from falls had subdural hematomas. Systolic BP (HR = 0.985 95% CI 0.972-0.997, p = 0.018), atrial fibrillation (HR = 2.652, 95% CI 1.506-4.872, p < 0.001) and creatinine (HR = 1.018, 95% CI 1.010-1.027, p < 0.001) were independently associated with mortality for iNPH.Discussion This long-term and population-matched cohort study indicates that in spite of CSF-shunt treatment, iNPH has shorter life expectancy. It may be important to treat iNPH in supplementary ways to reduce mortality. Both cardiovascular comorbidities and lethal falls are contributing to the excess mortality in iNPH and reducing these preventable risks should be an established part of the treatment plan.

Abstract [en]

Aims The aim of this study was to determine if single items in the quality of life questionnaire short form 36 (SF36) were associated with cardiovascular events in patients with type 2 diabetes mellitus (T2DM). Methods In 756 T2DM patients (260 women) from the CARDIPP study, nine questions from the domains vitality and well-being in SF36 were analysed. Patients, 55-66 years, were recruited in 2005-2008 and followed up until 31 December 2018 for the incidence of major adverse cardiovascular events (MACE), that is, myocardial infarction, stroke or cardiovascular death. Results Median follow-up time: 11.6 years, during which 119 (16%) MACE occurred. The SF36 items: seldom full of pep (HR 1.2, 95% CI: 1.1-1.4, p = 0.006), seldom a lot of energy (HR 1.3, 95%CI: 1.1-1.5, p < 0.001), worn out (HR 1.2, 95%CI: 1.0-1.4, p = 0.020) and seldom happy (HR 1.2, 95%CI: 1.0-1.4, p = 0.012) were independent risk factors for MACE in separate models, as well as male sex, diabetes duration, HbA(1c), sagittal abdominal diameter and aortic pulse wave velocity. The variables seldom full of pep and seldom a lot of energy remained associated with MACE when conducting separate analyses for sexes. Only seldom a lot of energy remained associated with MACE when all items from SF-36 were comprised in the same model. Conclusions One single question regarding energy levels from SF36 may be used as an independent risk factor for cardiovascular events in T2DM patients in primary care, for both men and women. This item may be included in future risk assessment for use in clinical practice for cardiovascular risk stratification of T2DM patients. Trial registration The study was registered in (NCT 01049737) in 14 January 2010.

Abstract [en]

OBJECTIVE Vascular risk factors (VRFs) may act synergistically, and clinical decision support tools (CDSTs) have been developed that present vascular risk as a summarized score. Because VRFs are a major issue in patients with idiopathic normal pressure hydrocephalus (INPH), a CDST may be useful in the diagnostic workup. The objective was to compare 4 CDSTs to determine which one most accurately predicts short-term outcome and 10-year mortality after CSF shunt surgery in INPH patients. METHODS One-hundred forty INPH patients who underwent CSF shunt surgery were included. For each patient, 4 CDST scores (Systematic Coronary Risk Evaluation-Older Persons [SCORE-OP], Framingham Risk Score [FRS], Revised Framingham Stroke Risk Profile, and Kiefers Comorbidity Index [KCI]) were estimated. Short-term outcome (3 months after CSF shunt surgery) was defined on the basis of improvements in gait, Mini-Mental State Examination score, and modified Rankin Scale score. The 10-year mortality rate after surgery was noted. The CDSTs were compared by using Cox regression analysis, receiver operating characteristic curve analysis, and the chi-square test. RESULTS For 3 CDSTs, increased score was associated with increased risk of 10-year mortality. A 1-point increase in the FRS indicated a 2% higher risk of death within 10 years (HR 1.02, 95% CI 1.003-1.035, p = 0.021); SCORE-OP, 5% (HR 1.05, 95% CI 1.019-1.087, p = 0.002); and KCI, 12% (HR 1.12, 95% CI 1.03-1.219, p = 0.008). FRS predicted short-term outcome of surgery (p = 0.024). When the cutoff value was set to 32.5%, the positive predictive value was 80% and the negative predictive value was 48% (p = 0.012). CONCLUSIONS The authors recommend using FRS to predict short-term outcome and 10-year risk of mortality in INPH patients. The study indicated that extensive treatment of the risk factors of INPH may decrease risk of mortality. Clinical trial registration no.: NCT01850914 (ClinicalTrials.gov)

Abstract [en]

Background: The use of cognitive behavioral therapy (CBT) to cope with mental distress and pain issues has helped many patients in primary health care in Sweden. However, the effects of CBT to reduce sick leave has not been equally convincing. Acceptance and Commitment Therapy (ACT) is an evolution of traditional CBT and we aimed to study if education based on ACT of the staff rather than the patients could reduce sick leave in primary health care. Methods: This was a prospective trial in 6 primary health care centers in Kalmar (total amount of registered subjects of 28,930) in which the staff (physicians, nurses and therapists) received group-based education according to ACT during 2018 and 2019. The effects were compared with 5 similarly sized control health care centers in the neighboring Region of Jonkoping in which no such education took place. The main aim was to study changes in sick leave in the 6 primary care centers of Kalmar and to keep track of more general trends by studying sick leave also in Jonkoping, letting sick leave in the year 2017 to be the reference period for both areas. Results: The staff at the health care centers in Kalmar reported to having attended a mean of 5.2 +/- 2 educational ACT-sessions with psychiatrist Kadowaki in Kalmar. Sick leave for ICD-10 F43 (reaction to severe stress and related adjustment-disorders) was reduced from a mean value of 28.7 +/- 9.1ongoing sick leaves/month in 2017 to 22.6 +/- 7.0 sick leaves/month in 2018 (-21%, p = 0.033) and to 18.1 +/- 10 sick leaves/month in 2019 (-37%, p = 0.038). The corresponding sick leave for any diagnosis (total sick leave) was reduced from 132 +/- 39 sick leaves/month in 2017 to 118 +/- 38 sick leaves/month in 2018 (-11%, p = 0.056) and to 102 +/- 37 sick leaves/month in 2019 (-21%, p = 0.021). The corresponding sick leave comparisons in the control health centers did not show any significant changes (all p-values >= 0.24). Conclusions: Total monthly mean sick leave was reduced 21% in the health care centers in Kalmar during the second year of the educational ACT intervention of the staff while it was unchanged in Jonkoping. This suggests a significant effect to induce a reduction in long-term sick leave for patients in primary health care in which the staff received education according to ACT. The results of this trial could serve as a basis for a randomized trial in order to ascertain causality.

Abstract [en]

BACKGROUND: Gait and balance impairment are typical symptoms of idiopathic normal pressure hydrocephalus (INPH), implicating that falls may afflict these patients. OBJECTIVE: To investigate falls, related injuries, and associated psychological features, before and after shunt surgery for INPH and compared to the general population. METHODS: The study included 176 patients shunted for INPH and 368 age- and sex-matched controls. Falls, fear of falling (FOF), fall-related injuries (mild-severe), confidence in avoiding falls (Swedish Falls Efficacy Scale (FES(S)), quality of life (QoL; EuroQoL 5-dimension 5 level instrument), and symptoms of depression (Geriatric Depression Scale 15) were investigated. Pre- and postoperative observational times were 12 mo before surgery and 21 mo after (mean). Recurrent fallers fell >= 2 times. RESULTS: More INPH patients than controls were recurrent fallers (67% vs 11%; P < .001). They feared falling more often (FOF, mean standard deviation: 3.3 +/- 1.1 vs 1.6 +/- 0.9; P < .001) and had lower confidence in avoiding falls (FES(S) 78 +/- 40 vs 126 +/- 14; P < .001). After surgery, INPH patients improved in all parameters but they did not reach the levels of the controls. Among fallers there was no difference between patients and controls in the severity of injuries suffered. Low QoL and symptoms of depression were more common among recurrent fallers than one-time or nonfallers in both shunted patients and controls (P <= .001). CONCLUSION: Falls, FOF, and low confidence in avoiding falls are considerable problems in INPH that may be reduced by shunt surgery. We suggest that remaining risk of falling and preventative measures are routinely considered in postoperative follow-ups and rehabilitation planning.

Abstract [en]

BACKGROUND: The short- and long-term impact of cerebrospinal fluid shunting onquality of life (QoL) in idiopathic normal pressure hydrocephalus (INPH) is poorly understood.OBJECTIVE: To investigate QoL in shunted INPH patients compared to the population andto investigate which factors influence QoL in INPH.METHODS: INPH patients consecutively shunted in Sweden during 2008-2010 were scrutinized. Population-based controls were age- and sex-matched to the patients. Includedparticipants were thefollowing: 176 INPH patients and 368 controls. QoL was assessed usingthe EuroQol 5-dimension 5-level (EQ5D5L) instrument, which measures overall QoL andhealth status in 5 dimensions. Independency (accommodation and/or need for in-homecare) and comorbidities were assessed. Patients were followed up 6-45 mo after surgery(mean follow-up time: 21 mo).RESULTS: Shunting improved QoL (P < .001) and health status in all dimensions (P < .005).Shunted INPH patients had lower QoL than controls (P < .001). The patients’ health statusin mobility, self-care, daily activities, and anxiety/depression was worse than the controlsboth before and after surgery (P < .001). The main predictors of low QoL in INPH weresymptoms of depression (P < .001) and severity of gait disturbance (P = .001). Fewer INPHpatients than controls lived independently (45% vs 85%, P < .001). Time after shunting hadno influence on QoL.CONCLUSION: QoL remains improved in shunted INPH patients at a mean follow-up timeof 21 mo, but the patients do not reach the same QoL as the population. Symptoms ofdepression and severity of gait disturbance are the strongest predictors of low QoL in INPH.

Abstract [en]

OBJECTIVE Idiopathic normal pressure hydrocephalus (INPH) is a dementia treatable by insertion of a shunt that drains CSF. The cause of the disease is unknown, but a vascular pathway has been suggested. The INPH-CRasH (Comorbidities and Risk Factors Associated with Hydrocephalus) study was a modern epidemiological case-control study designed to prospectively assess parameters regarding comorbidities and vascular risk factors (VRFs) for INPH, quality of life (QOL), and adverse events in patients with shunted INPH. The objective of this review was to summarize the findings of the INPH-CRasH study. METHODS VRFs, comorbidities, QOL, and adverse events were analyzed in consecutive patients with INPH who underwent shunt placement between 2008 and 2010 in 5 of 6 neurosurgical centers in Sweden. Patients (n = 176, within the age span of 60-85 years and not having dementia) were compared to population-based age- and gender-matched controls (n = 368, same inclusion criteria as for the patients with INPH). Assessed parameters were as follows: hypertension; diabetes; obesity; hyperlipidemia; psychosocial factors (stress and depression); smoking status; alcohol intake; physical activity; dietary pattern; cerebrovascular, cardiovascular, or peripheral vascular disease; epilepsy; abdominal pain; headache; and clinical parameters before and after surgery. Parameters were assessed through questionnaires, clinical examinations, measurements, ECG studies, and blood samples. RESULTS Four VRFs were independently associated with INPH: hyperlipidemia, diabetes, obesity, and psychosocial factors. Physical inactivity and hypertension were also associated with INPH, although not independently from the other risk factors. The population attributable risk percent for a model containing all of the VRFs associated with INPH was 24%. Depression was overrepresented in patients with INPH treated with shunts compared to the controls (46% vs 13%, p &lt; 0.001) and the main predictor for low QOL was a coexisting depression (p &lt; 0.001). Shunting improved QOL on a long-term basis. Epilepsy, headache, and abdominal pain remained common for a mean follow-up time of 21 months in INPH patients who received shunts. CONCLUSIONS The results of the INPH-CRasH study are consistent with a vascular pathophysiological component of INPH. In clinical care and research, a complete risk factor analysis as well as screening for depression and a measurement for QOL should probably be included in the workup of patients with INPH. The effect of targeted interventions against modifiable VRFs and antidepressant treatment in INPH patients should be evaluated. Seizures, headache, and abdominal pain should be inquired about at postoperative follow-up examinations.

Abstract [en]

Objective: To describe survival and causes of death in 979 treated iNPH patients from the Swedish Hydrocephalus Quality Registry (SHQR), and to examine the influence of comorbidities, symptom severity and postoperative outcome.

Methods: All 979 patients operated for iNPH 2004–2011 and registered in the SHQR were included. A matched control group of 4890 persons from the general population was selected by Statistics Sweden. Data from the Swedish Cause of Death Registry was obtained for patients and controls.

Results: At a median 5.9 (IQR 4.2–8.1) year follow-up, 37% of the iNPH patients and 23% of the controls had died. Mortality was increased in iNPH patients by a hazard ratio of 1.81, 95% CI 1.61–2.04, p < 0.001. More pronounced symptoms in the preoperative ordinal gait scale and the Mini-mental State Examination were the most important independent predictors of mortality along with the prevalence of heart disease. Patients who improved in both the gait scale and in the modified Rankin Scale postoperatively (n = 144) had a similar survival as the general population (p = 0.391). Deaths due to cerebrovascular disease or dementia were more common in iNPH patients, while more controls died because of neoplasms or disorders of the circulatory system.

Conclusions: Mortality in operated iNPH patients is 1.8 times increased compared to the general population, a lower figure than previously reported. The survival of iNPH patients who improve in gait and functional independence is similar to that of the general population, indicating that shunt surgery for iNPH, besides improving symptoms and signs, can normalize survival.

Abstract [en]

OBJECTIVE Adverse events related to shunt surgery are common and might have a negative effect on outcome in patients with idiopathic normal pressure hydrocephalus (INPH). The authors' objectives were to establish the frequencies of epilepsy, headache, and abdominal pain and determine their impact on patient quality of life (QOL), in long-term follow-up after shunt surgery for INPH.

METHODS One hundred seventy-six shunt-treated patients with INPH (mean age 74 years) and 368 age- and sex-matched controls from the population were included. The mean follow-up time after surgery was 21 months (range 6-45 months). Each participant answered a questionnaire regarding present frequency and severity of headache and abdominal pain. Confirmed diagnoses of epilepsy and all prescriptions for antiepileptic drugs (AEDs) before and after shunt surgery for INPH were gathered from national registries. Equivalent presurgical and postsurgical time periods were constructed for the controls based on the date of surgery (the division date for controls is referred to as virtual surgery). All registry data covered a mean period of 6 years (range 3-8 years) before surgery/virtual surgery and 4 years (range 2-6 years) after surgery/virtual surgery. Provoked epileptic seizures were excluded. Patient QOL was assessed with the EuroQoL 5-dimension 5-level instrument.

RESULTS Epilepsy was more common in shunt-treated patients with INPH than in controls (4.5% vs 1.1%, respectively; p = 0.023), as was treatment with AEDs (14.8% vs 7.3%, respectively; p = 0.010). No difference was found between the populations before surgery/virtual surgery (epilepsy, 2.3% [INPH] vs 1.1% [control], p = 0.280; AED treatment, 8.5% [INPH] vs 5.4% [control], p = 0.235). New-onset epilepsy and new AED treatment after surgery/virtual surgery were more common in INPH (epilepsy, 2.3% [INPH] vs 0.0% [control], p = 0.011; AED, 8.5% [INPH] vs 3.3% [control], p = 0.015). At follow-up, more patients with INPH than controls experienced headache several times per month or more often (36.1% vs 11.6%, respectively; p < 0.001). Patients with INPH and unilateral headache had more right-sided headaches than controls (p = 0.038). Postural headache was experienced by 16% (n = 27 of 169) of the patients with INPH. Twenty percent (n = 35) of the patients with INPH had persistent abdominal pain. Headache was not correlated to lower QOL. The study was underpowered to draw conclusions regarding QOL in patients with INPH who had epilepsy and abdominal pain, but the finding of no net difference in mean QOL indicates that no correlation between them existed.

CONCLUSIONS Epilepsy, headache, and abdominal pain are common in long-term follow-up in patients after shunt surgery for INPH and are more common among patients with INPH than in the general population. All adverse events, including mild and moderate ones, should be considered during postoperative follow-ups and in the development of new methods for shunt placement.
