Interaction between geriatric syndromes in predicting three months mortality risk.

OBJECTIVES: Capturing frailty using a quick tool has proven to be challenging. We hypothesise that this is due to the complex interactions between frailty domains. We aimed to identify these interactions and assess whether adding interactions between domains improves mortality predictability. METHODS: In this retrospective cohort study, we selected all patients aged 70 or older who were admitted to one Dutch hospital between April 2015 and April 2016. Patient characteristics, frailty screening (using VMS (Safety Management System), a screening tool used in Dutch hospital care), length of stay, and mortality within three months were retrospectively collected from electronic medical records. To identify predictive interactions between the frailty domains, we constructed a classification tree with mortality as the outcome using five variables: the four VMS-domains (delirium risk, fall risk, malnutrition, physical impairment) and their sum. To determine if any domain interactions were predictive for three-month mortality, we performed a multivariable logistic regression analysis. RESULTS: We included 4,478 patients. (median age: 79 years; maximum age: 101 years; 44.8% male) The highest risk for three-month mortality included patients that were physically impaired and malnourished (23% (95%-CI 19.0-27.4%)). Subgroups had comparable three-month mortality risks based on different domains: malnutrition without physical impairment (15.2% (96%-CI 12.4-18.6%)) and physical impairment and delirium risk without malnutrition (16.3% (95%-CI 13.7-19.2%)). DISCUSSION: We showed that taking interactions between domains into account improves the predictability of three-month mortality risk. Therefore, when screening for frailty, simply adding up domains with a cut-off score results in loss of valuable information.

Predictive value of selected geriatric parameters for postoperative outcomes in older patients with rectal cancer - A multicenter cohort study.

INTRODUCTION: Older patients have a higher risk for complications after rectal cancer surgery. Although screening for geriatric impairments may improve risk prediction in this group, it has not been studied previously. METHODS: We retrospectively investigated patients ≥70 years with elective surgery for non-metastatic rectal cancer between 2014 and 2018 in nine Dutch hospitals. The predictive value of six geriatric parameters in combination with standard preoperative predictors was studied for postoperative complications, delirium, and length of stay (LOS) using logistic regression analyses. The geriatric parameters included the four VMS-questionnaire items pertaining to functional impairment, fall risk, delirium risk, and malnutrition, as well as mobility problems and polypharmacy. Standard predictors included age, sex, body mass index, American Society of Anesthesiologists (ASA)-classification, comorbidities, tumor stage, and neoadjuvant therapy. Changes in model performance were evaluated by comparing Area Under the Curve (AUC) of the regression models with and without geriatric parameters. RESULTS: We included 575 patients (median age 75 years; 32% female). None of the geriatric parameters improved risk prediction for complications or LOS. The addition of delirium risk to the standard preoperative prediction model improved model performance for predicting postoperative delirium (AUC 0.75 vs 0.65, p = 0.03). CONCLUSIONS: Geriatric parameters did not improve risk prediction for postoperative complications or LOS in older patients with rectal cancer. Delirium risk screening using the VMS-questionnaire improved risk prediction for delirium. Older patients undergoing rectal cancer surgery are a pre-selected group with few impairments. Geriatric screening may have additional value earlier in the care pathway before treatment decisions are made.

Outcomes of surgical treatment of non-metastatic gastric cancer in patients aged 70 and older: A systematic review and meta-analysis.

The optimal surgical treatment strategy for gastric cancer in older patients needs to be carefully evaluated due to increased vulnerability of older patients. We performed a database search for randomized controlled trials (RCTs) and cohort studies that included patients ≥70 years with potentially resectable stage I-III gastric cancer. Postoperative and survival outcomes were compared between groups undergoing 1) gastrectomy vs conservative treatment (best supportive care or non-operative treatment), 2) minimally invasive (MIG) vs open gastrectomy (OG), or 3) extended vs limited lymphadenectomy. When possible, results were pooled using risk ratios (RR). Thirty-one studies were included. Six retrospective studies compared overall survival (OS) between gastrectomy (N = 2332) and conservative treatment (N = 246). Longer OS was reported in the gastrectomy group in all studies, but study quality was low and meta-analysis was not feasible. Eighteen cohort studies compared MIG (N = 3626) and OG (N = 5193). MIG was associated with fewer complications (pooled RR 0.68, 95% confidence interval 0.54-0.84). OS was not different between the groups. Two RCTs and five cohort studies compared outcomes between extended (N = 709) and limited lymphadenectomy (N = 1323). Complication rates were comparable between the groups. Two cohort studies found longer OS or cancer-specific survival after extended lymphadenectomy. No quality of life (QoL) or functional outcomes were reported. In older patients with gastric cancer, there is low-quality evidence for better OS after gastrectomy vs conservative treatment. Compared to OG, MIG was associated with less postoperative morbidity. The evidence to support extended lymphadenectomy is limited. QoL and functional outcomes should be addressed in future studies.

Fit4Surgery for cancer patients during covid-19 lockdown - A systematic review and meta-analysis.

BACKGROUND: Prehabilitation is a promising method to enhance postoperative recovery, especially in patients suffering from cancer. Particularly during times of social distancing, providing home-based programmes may have become a suitable solution to increase compliance and effectiveness. METHODS: In line with the PRISMA guidelines, a systematic review was conducted including trials that investigated the effect of home-based prehabilitation (HBP) in patients undergoing surgery for cancer. The primary outcome was postoperative functional capacity (6 min walk test, 6MWT). Secondary outcomes were postoperative complications and compliance. RESULTS: Five randomized controlled trials were included with 351 patients undergoing surgery for colorectal cancer, oesophagogastric cancer, bladder cancer and non-small cell lung cancer. Three studies presented results of significant progress after eight weeks. The meta-analysis showed a significant improvement of the 6MWT in the prehabilitation group compared to the control group preoperatively (MD 35.06; 95% CI 11.58 to 58.54; p = .003) and eight weeks postoperatively (MD 44.91; 95% CI 6.04 to 83.79; p = .02) compared to baseline. Compliance rate varied from 63% to 83% with no significant difference between prehabilitation and control groups. These data must be interpreted with caution because of a high amount of heterogeneity and small sample sizes. DISCUSSION: In conclusion, HBP may enhance overall functional capacity of patients receiving oncological surgery compared to standard of care. This could be a promising alternative to hospital-based prehabilitation regarding the current pandemic and further digitalization in the future. In order to increase accessibility and effectiveness of prehabilitation, home-based solutions should be further investigated.

Does the Dutch Safety Management Program predict adverse outcomes for older patients in the emergency department?

PURPOSE: Frailty screening in the emergency department may identify frail patients at risk for adverse outcomes. This study investigated if the Dutch Safety Management Program (VMS) screener predicts outcomes in older patients in the emergency department. METHODS: In this prospective cohort study, patients aged 70 years or older presenting to the emergency department were recruited on workdays between 10:00 AM and 7:00 PM from May 2017 until August 2017. Patients were screened in four domains: activities of daily living, malnutrition, risk of delirium, and risk of falling. After 90 days of follow up, mortality, functional decline, living situation, falls, readmission to the emergency department, and readmission to the hospital were recorded. VMS was studied using the total VMS score as a predictor with ROC curve analysis, and using a cut-off point to divide patients into frail and non-frail groups to calculate positive predictive value (PPV) and negative predictive value (NPV). RESULTS: A total of 249 patients were included. Higher VMS score was associated with 90-day mortality (AUC 0.65, 95% CI 0.54-0.76) and falling (AUC 0.67, 95% CI 0.56-0.78). VMS frailty predicted mortality (PPV 0.15, NPV 0.94, p = 0.05) and falling (PPV 0.22, NPV 0.92, p = 0.02), but none of the other outcomes. CONCLUSION: In this selected group of patients, higher VMS score was associated with 90-day mortality and falls. The low positive predictive value shows that the VMS screener is unsuitable for identifying high-risk patients in the ED. The high negative predictive value indicates that the screener can identify patients not at risk for adverse medical outcomes. This could be useful to determine which patients should undergo additional screening.

Differences at surgery between patients with bicuspid and tricuspid aortic valves.

AIM: To determine differences in surgical procedures and clinical characteristics at the time of surgery between native bicuspid aortic valves (BAV) and tricuspid aortic valves (TAV) in patients being followed up after aortic valve surgery (AVS). METHODS: In this retrospective cohort study in a non-academic hospital, we identified patients who had a surgeon's report of the number of native valve cusps and were still being followed up. We selected patients with BAV and TAV, and used multivariable regression analyses to identify associations between BAV-TAV and pre-specified clinical characteristics. RESULTS: Of 439 patients, 140 had BAV (32%) and 299 TAV (68%). BAV patients were younger at the time of surgery (mean age 58.6 ± 13 years) than TAV patients (69.1 ± 12 years, p < 0.001) and were more often male (64% vs 53%; p = 0.029). Cardiovascular risk factors were less prevalent in BAV than in TAV patients at the time of surgery (hypertension (31% vs 55%), hypercholesterolaemia (29% vs 58%) and diabetes (7% vs 16%); all p < 0.005). Concomitant coronary artery bypass grafting (CABG) was performed less often in BAV than in TAV patients (14% vs 39%, p < 0.001), even when adjusted for confounders (adjusted odds ratio (adj.OR) 0.45; 95% CI: 0.25-0.83). In contrast, surgery of the proximal aorta was performed more often (31% vs 11%, respectively, p < 0.001; adj.OR 2.3; 95% CI: 1.3-4.0). CONCLUSIONS: Whereas mechanical stress is the supposed major driver of valvulopathy towards AVS in BAV, prevalent cardiovascular risk factors are a suspected driver towards the requirement for AVS and concomitant CABG in TAV, an observation based on surgical determination of the number of valve cusps.

Video-head impulse test results in patients with Menière's disease related to duration and stage of disease.

BACKGROUND: The video-head impulse test employs the vestibulo-ocular reflex (VOR) to assess vestibular function. To this day, no consensus has been reached among scientists in terms of whether or not vHIT results change in MD patients as the disease progresses. OBJECTIVE: To assess whether the vHIT is more often abnormal in later stages of MD compared to earlier stages. METHODS: We retrospectively analyzed patients with 'definite' MD who had undergone a vHIT and caloric test between 2012 and 2015. Patients were evaluated based on duration of disease in years (≤1, >1≤5, >5≤10, >10) and stage of disease (stage I and II versus III and IV). For the vHIT, an abnormal vestibulo-ocular reflex was defined as a gain cut-off value of≤0.8 and presence of correction saccades including subanalyses using a cut-off value of≤0.9. RESULTS: In 89 definite MD patients (42 (47%) male, mean age 55±5 (SD)), data on both the caloric test and the vHIT were available. The risk of an abnormal vHIT was 25% in patients with a duration of disease over 10 years compared to 22% in the patients with a disease duration of 10 years or less (risk difference 3%, 95% CI:- 28% to 35%), p = 0.82). The risk for an abnormal vHIT in the Stage I and Stage II was 17% compared to 26% in Stage III and IV (risk difference 9%, 95% CI:- 30% to 11%). When using a cut-off value of 0.9 we also did not demonstrate a relationship between the duration of disease and the proportion of abnormal vHIT test results. CONCLUSIONS: There is no relationship between the proportion of abnormal vHIT test results in patients with MD in either duration or stage of disease.

[Septic arthritis after intra-articular injection is rare: does the Taskforce Infection Prevention use a sledgehammer to crack a nut?] / Septische artritis na gewrichtspunctie is zeldzaam.

OBJECTIVE: To determine the incidence of septic arthritis (SA) after a joint puncture and reconsider the value of the hygiene measures stipulated by the Taskforce Infection Prevention (TIF). DESIGN: Prospective study. METHOD: We determined the number of joint punctures among general practitioners and specialists in the Apeldoorn area during a three-month period (from October 1, 2013 to December 31, 2013). Secondly, we performed an analysis on the incidence of SAs in this period and the subsequent month, and ascertained if these were related to a joint puncture. Finally, we conducted a retrospective analysis on joint puncture related SA during the period January 2008 - December 2013. This was executed to determine whether our results were representative. RESULTS: The incidence of SA after a joint puncture was 1 in 27,000. CONCLUSION: The incidence of SA after a joint puncture can be considered low. Due to the low baseline incidence, we anticipate that it is unlikely that the prescriptive measures outlined by TIF will lead to a cost-effective reduction in incidence of SA.

Detecting intrinsic muscle weakness of the hallux as an addition to early-stage screening of the feet in patients with diabetes.

AIMS: Present-day screening of the diabetic foot involves the Semmes Weinstein Monofilament Test for evaluating loss of sensibility, while testing for intrinsic muscle weakness is not implied. Just as with the early detection of sensibility loss, early detection of intrinsic muscle weakness might have important implications for the prevention of both ulceration and deformity in patients with diabetes. The purpose of this study is to investigate the prevalence of patients with diabetes presenting intrinsic muscle weakness of the hallux, but with a normal sensibility of the sole of the foot. METHODS: A cross-sectional study design was applied. Intrinsic muscle function of the hallux was measured with the Paper Grip Test, while sensibility of the sole of the foot was measured with the Semmes Weinstein Monofilament Test 5.07/10-g. RESULTS: In a period of three months a total of 266 patients with diabetes (mean age 60, 134 females (50%), 177 type 2 diabetes mellitus (67%)) met the inclusion criteria and were examined for both intrinsic muscle weakness of the hallux and sensibility of the soles of the feet. The results showed that intrinsic muscle weakness was present more frequent in patients with impaired sensibility (P=0.001), also 20% of the population had intrinsic muscle weakness in the presence of normal sensibility. Multivariate regression analysis showed that only age is associated with patients with diabetes presenting normal sensibility but impaired intrinsic muscle function (P=0.017). CONCLUSIONS: The Paper Grip Test could have added value to current physical examination of the feet in patients with diabetes.

Age of onset of Ménière's disease in the Netherlands: data from a specialised dizziness clinic.

OBJECTIVES: To determine the age of onset of Ménière's disease in patients who visited a specialised dizziness clinic, and to verify whether the trend of a delayed onset age of Ménière's disease as reported for the Japanese population also occurs in the Netherlands. METHOD: A retrospective data analysis was performed of patients diagnosed with 'definite' Ménière's disease who visited our clinic between January 2000 and December 2013. RESULTS: Mean onset age of Ménière's disease among the 296 patients was 53.0 ± 14.1 years; 209 patients (71 per cent) were diagnosed between the fifth and seventh decades of life. No trend towards a later onset of Ménière's disease was found (regression beta co-efficient for year of presentation was 0.03; 95 per cent confidence interval = -0.34-0.61; p = 0.58). CONCLUSION: Ménière's disease has a peak incidence between 40 and 69 years of age. No shift towards a later onset age of Ménière's disease was found.

Determining vestibular hypofunction: start with the video-head impulse test.

Caloric testing is considered the 'reference standard' in determining vestibular hypofunction. Recently, the video-head impulse test (vHIT) was introduced. In the current study we aimed to assess the diagnostic value of the vHIT as compared to caloric testing in determining vestibular function. In a cross-sectional study between May 2012 and May 2013, we prospectively analysed patients with dizziness who had completed caloric testing and the vHIT. For the left and right vestibular system we calculated the mean vHIT gain. We used a gain cut-off value of 0.8 for the vHIT and presence of correction saccades to define an abnormal vestibular-ocular reflex. An asymmetrical ocular response of 22 % or more (Jongkees formula) or an irrigation response with a velocity below 15°/s was considered abnormal. We calculated sensitivity, specificity, positive and negative predictive values with 95 % confidence intervals for the dichotomous vHIT. Among 324 patients [195 females (60 %), aged 53 ± 17 years], 39 (12 %) had an abnormal vHIT gain and 113 (35 %) had an abnormal caloric test. Sensitivity was 31 % (23-40 %), specificity 98 % (95-99 %), positive predictive value was 88 % (74-95 %), and negative predictive value 73 % (67-77 %). In case of vHIT normality, additional caloric testing remains indicated and the vHIT does not replace the caloric test. However, the high positive predictive value of the vHIT indicates that an abnormal vHIT is strongly related to an abnormal caloric test result; therefore, additional caloric testing is not necessary. We conclude that the vHIT is clinically useful as the first test in determining vestibular hypofunction in dizzy patients.

Dizziness causes absence from work.

The objective of the study was to assess absenteeism from work due to dizziness in patients referred to a tertiary centre. Consecutive patients with a paid employment completed the WHO Health and work Performance Questionnaire, including items on work absence in the past 7 days and 4 weeks, and the Dizziness Handicap Inventory. Of the 400 patients [55% females, mean age 46.3 years (SD 10.8), range 18-68 years], 46 (12%) indicated they were completely disabled to work due to dizziness, while 202 (51%) patients indicated they had worked less than expected due to dizziness. Patients with more disease-related disabilities had more absenteeism from work. Half of the patients who are referred to a tertiary centre for dizziness report work absenteeism due to their complaints, and 12% is completely disabled to work.

Prevalence of unrecognized benign paroxysmal positional vertigo in older patients.

Dizziness is a relatively common complaint which occurs more often with increasing age. Benign paroxysmal positional vertigo (BPPV) is an important cause which can easily be treated but is frequently not recognized by professionals. The aim of this study was to assess the prevalence of unrecognized BPPV in older patients. Patients ≥70 years of age (n = 989) indicated whether they experienced dizziness, and if so whether the symptoms were typical for BPPV. If affirmed, a diagnostic maneuver was performed. Positive patients were treated at once. All suspected patients completed quality of life questionnaires and were followed for 3 and 6 months. Positive BPPV patients were compared with negative (but suspected) patients. Almost one quarter of the patients (226 patients, 23 %) suffered from dizziness, among whom 101 were suspected of BPPV. Less than half (n = 45) underwent the diagnostic maneuver, of whom 13 (29 %) were positive for BPPV. At follow-up, one patient developed BPPV, leading to a total of 14 positive patients (overall prevalence 1.4 %). BPPV positive patients did not differ from BPPV negative patients. Among a large group of older patients, one quarter experiences dizziness, and 1.4 % has definite BPPV.

Follow-up of mesh complications using the IUGA/ICS category-time-site coding classification.

INTRODUCTION: The International Urogynecological Association (IUGA) and the International Continence Society (ICS) developed a complication classification to facilitate international comparison and to improve our understanding of complications. This code was applied to surgical cases for the analysis of complications after mesh insertion. METHODS: The study included patients who had undergone vaginal prolapse repair with a trocar-guided polypropylene mesh between 2006 and 2010 in a Dutch peripheral hospital. Complications were assessed at secondary follow-up and classified using category (C), timing (T), and site (S) components (CTS). RESULTS: Of the 107 women included, 84 returned for secondary follow-up (response rate 80 %, median time after surgery 36 months, range 12-64). In 45 patients no complications occurred. In the remaining 39 patients, 43 complication codes were established. Six of the seven categories of complications were found at all different time codes. Concerning the site of the complication codes S1, S2, and S3 were applicable. Perioperative complications (6 %) included hemorrhage and bladder perforation. Six patients were reoperated for symptomatic mesh exposure or local pain. At secondary follow-up exposure was diagnosed in another 4 patients (12 %). In 36 % mesh wrinkling or shrinkage was discovered, although without complaints in most. Eight women had daily complaints or dyspareunia. Eighty-two percent of patients indicated strong improvement after surgery. Several limitations of the classification are discussed. CONCLUSIONS: Despite limitations, the IUGA/ICS code is demonstrated to be useful in describing mesh complications. We advise the use of the CTS code at follow-up consultations after a minimum of 2 years for improved insight into and knowledge on the occurrence of complications.

A randomised sham-controlled trial to assess the long-term effect of the Epley manoeuvre for treatment of posterior canal benign paroxysmal positional vertigo.

OBJECTIVE: To evaluate the long-term efficacy of the Epley manoeuvre as a therapeutic procedure for posterior canal benign paroxysmal positional vertigo. DESIGN: Randomised, double-blind, sham-controlled trial. SETTING: A multidisciplinary dizziness unit in a non-academic Hospital. PARTICIPANTS: Forty-four patients with posterior canal benign paroxysmal positional vertigo (BPPV) with a duration of at least 1 month. Participants were randomised in two groups of 22 and treated with either the Epley manoeuvre or a sham manoeuvre and followed up for 1 year after treatment. MAIN OUTCOME MEASURES: Conversion of a 'positive' Dix-Hallpike test to a 'negative' Dix-Hallpike test, impairments perceived by the dizziness assessed by the Dizziness Handicap Inventory (DHI). STATISTICAL ANALYSIS: Absolute and relative risks were computed, and Fisher's exact test was used to compare the treatments. RESULTS: Six patients were lost to follow up (five in the sham group, one in the Epley group). The Epley procedure resulted in a treatment success in 20/22 patients (91%) after 12 months of follow-up, whereas the sham procedure had a positive effect in 10/22 patients (46%; P = 0.001). The DHI was significantly lower in the Epley group at all follow-up assessments (median scores 12 months 0 (0-51) versus 20 (0-76), P = 0.003). CONCLUSION: The Epley manoeuvre provides long-term resolution of symptoms in patients with posterior canal BPPV.

The prognostic value of micrometastases and isolated tumour cells in histologically negative lymph nodes of patients with colorectal cancer: a systematic review and meta-analysis.

INTRODUCTION: Detection of occult tumour cells in lymph nodes of patients with stage I/II colorectal cancer is associated with decreased survival. However, according to recent guidelines, occult tumour cells should be categorised in micrometastases (MMs) and isolated tumour cells (ITCs). This meta-analysis evaluates the prognostic value of MMs and of ITCs, separately. METHODS: PubMed, Embase, Biosis and the World Health Organization International Trials Registry Platform were searched for papers published until April 2013. Studies on the prognostic value of MMs and ITCs in lymph nodes of stage I/II colorectal cancer patients were included. Odds ratios (ORs) for the development of disease recurrence were calculated to analyse the predictive value of MMs and ITCs. RESULTS: From five papers, ORs for disease recurrence could be calculated for MMs and ITCs separately. In patients with colorectal cancer, disease recurrence was significantly increased in the presence of MMs in comparison with absent occult tumour cells (OR 5.63; 95%CI 2.4-13.13). This was even more pronounced in patients with colon cancer (OR 7.25 95% CI 1.82-28.97). In contrast, disease recurrence was not increased in the presence of ITCs (OR 1.00 95% CI 0.53-1.88). CONCLUSION: Patients with stage I/II colorectal cancer and MMs have a worse prognosis than patients without occult tumour cells. However, ITCs do not have a predictive value. The distinction between ITCs and MMs should be made if the detection of occult tumour cells is incorporated in the clinical decision for adjuvant treatment.

Benign paroxysmal positional vertigo in Parkinson's disease.

BACKGROUND: Dizziness is a frequent complaint of patients with Parkinson's disease (PD), and orthostatic hypotension (OH) is often thought to be the cause. We studied whether benign paroxysmal positional vertigo (BPPV) could also be an explanation. AIM: To assess the prevalence of benign paroxysmal positional vertigo in patients with Parkinson's disease, with and without dizziness. METHODS: 305 consecutive outpatients with PD completed the Movement Disorders Society-sponsored revision of the Unified Parkinsons' Disease Rating Scale-motor score, the Dizziness Handicap Inventory, the Dix-Hallpike maneuver and a test for orthostatic hypotension. When positive for benign paroxysmal positional vertigo, a repositioning maneuver was performed. Patients were followed for three months to determine the clinical response. RESULTS: 305 patients responded (186 men (61%), mean age 70.5 years (Standard Deviation 9.5 years)), of whom 151 (49%) complained of dizziness. 57 (38%) of the dizzy patients appeared to have orthostatic hypotension; 12 patients (8%) had a classical but previously unrecognized benign paroxysmal positional vertigo. A further four patients (3%) had a more atypical presentation of benign paroxysmal positional vertigo. Three months after treatment, 11 (92%) of patients with classical benign paroxysmal positional vertigo were almost or completely without complaints. We found no 'hidden' benign paroxysmal positional vertigo among patients without dizziness. The prevalence of benign paroxysmal positional vertigo among all patients with PD was 5.3%. CONCLUSION: Among Parkinson patients with symptoms of dizziness, up to 11% may have benign paroxysmal positional vertigo, which can be treated easily and successfully.

Right ventricular ejection fraction measured by multigated planar equilibrium radionuclide ventriculography is an independent prognostic factor in patients with ischemic heart disease.

BACKGROUND: The number of studies on the prognostic value of the right ventricular ejection fraction (RVEF) in patients with ischemic heart disease (IHD) is limited, whereas it is widely accepted that the left ventricular ejection fraction (LVEF) is a strong prognostic factor. We assessed whether RVEF measured by multigated planar equilibrium radionuclide ventriculography (RNV) is an independent prognostic factor in patients with IHD. METHODS AND RESULTS: We retrospectively identified 347 consecutive patients with IHD (mean age 71 ± 11 years; 18% women) who underwent multigated planar equilibrium RNV between 2004 and 2008 to determine the LVEF, which also provided the RVEF (mean 44.7% ± 11.0%). We categorized patients according to RVEF in ≥40% (n = 240) and <40% (n = 107). Patients were followed for a median of 826 days (range 3-2,400) for the occurrence of events [all-cause mortality (n = 60), cardiac mortality (n = 33), and cardiac hospitalization (n = 78)]. Cox regression analysis with significant univariate predictors [coronary artery revascularization (P = .003), diuretics (P = .03), and statins (P < .001)] showed that an RVEF <40% was associated with a 2.90 (1.68-5.00)-fold higher risk of all-cause death. Accordingly, a decreased RVEF was associated with a 2.15 (1.34-3.43)-fold increase in the risk of cardiac hospitalization and a 5.11(2.32-11.23)-fold risk of cardiac death. CONCLUSION: RVEF measured by multigated planar equilibrium RNV is an independent prognostic factor in patients with chronic IHD.

Dizziness impairs health-related quality of life.

PURPOSE: Relatively little is known about the level of impairment in patients with dizziness. RESEARCH QUESTION: How much does dizziness impair the quality of life of patients referred to a multidisciplinary dizziness unit? PATIENTS AND METHODS: All 2,252 patients completed the Dutch version of the Dizziness Handicap Inventory (DHI-D; score 0-100 with higher scores representing more impairment). The results were classified into three categories: mild, moderate, and severe impairment. The three domains in the DHI representing physical, functional, and emotional aspects of dizziness were compared, as well as DHI scores of men versus women, between diagnoses, and the relationship between DHI and age. RESULTS: A total of 2,242 patients (64% women, mean age 54 years) completed the DHI with a mean score of 40.6. Almost 70% of patients had moderate or severe complaints. The handicap perceived by patients was primarily caused by physical and functional factors and less by emotional factors. Female patients and patients with hyperventilation syndrome and/or anxiety disorder had significantly higher DHI scores on all subscales. There was an S-shaped relationship between DHI score and age, and older patients reported more impairment. CONCLUSION: Dizziness has considerable impact on health-related quality of life of dizzy patients.
