Osteoporotische Wirbelkörperfrakturen

Zusammenfassung Hintergrund Osteoporotische Wirbelkörperfrakturen sind eine häufige Verletzung alter Menschen, deren optimale Behandlung (konservativ oder operativ) diskutiert wird. Die Literatur beschreibt nach Wirbelkörperaugmentationen geringere Mortalitäten als nach konservativer Therapie. Ob eine positive Korrelation des operativen Vorgehens mit dem Überleben nach oben genannten Verletzungen besteht, soll im eigenen alterstraumatologischen Patientenkollektiv überprüft werden. Methodik Es erfolgte die Erfassung aller Patienten, die mit einer osteoporotischen Wirbelkörperfraktur vom 01.02.2014 bis 31.01.2015 auf einer alterstraumatologischen Station behandelt wurden. Im Rahmen eines 2‑Jahres-Follow-up wurden diese auf die assoziierte Sterblichkeit untersucht, wobei insbesondere der Einfluss der Therapie untersucht wurde. Ergebnisse Insgesamt konnten 74 Patienten (Rücklauf 74 %) mit einem durchschnittlichen Alter von 83,2 Jahren eingeschlossen werden, davon wurden 40 konservativ und 34 operativ versorgt. Die gesamte Ein- und Zweijahresmortalität betrugen 29,7 % bzw. 35,1 %, nach operativer Versorgung 20,6 % bzw. 23,5 % und nach konservativer Therapie 37,5 % bzw. 45 % (p = 0,113 bzw. 0,086, Chi-Quadrat-Test). Die um Störfaktoren bereinigte „hazard ratio“ betrug 2,0 (95 %-KI: 0,686–6,100) Diskussion Auch wenn möglicherweise wegen der eher geringen Fallzahl kein signifikantes Ergebnis nachgewiesen werden konnte, zeigen die Analysen eine Tendenz des verbesserten Überlebens nach operativem Vorgehen. Dies steht im Einklang mit internationalen Studien. Bestehende Untersuchungen lassen vermuten, dass die Reduktion der Kyphosierung durch die Operation einen wichtigen kausalen Zusammenhang darstellen könnte.

Hypertensive Schwangerschaftserkrankungen

Zusammenfassung. Kardiovaskuläre Erkrankungen sind eine Hauptursache für Morbidität und Mortalität. Es ist vordringlich, diese Bedrohung zu minimieren. Hypertensive Schwangerschaften treten einerseits bevorzugt bei Frauen auf, die zu kardiovaskulären Erkrankungen tendieren, andererseits prädisponieren hypertensive Schwangerschaftserkrankungen, z.B. eine Präeklampsie, für spätere kardiovaskuläre Komplikationen. So sollten präventive Massnahmen schon früh nach der akuten Erkrankungen dieses Risiko reduzieren. Dazu gehört die Information bezüglich eines gesunden Lebensstil und zukünftige hausärztliche Kontrolluntersuchungen der kardiovaskulären Risikoindikatoren. In ähnlicher Weise sind Kinder mit einem erniedrigten Geburtsgewicht bzw. Mangelgeburtlichkeit für ein gegebenes Gestationsalter betroffen. Da diese Geburtskomplikationen häufiger bei hypertensiven Schwangerschaftserkrankungen auftreten, sollten den Müttern vergleichbare langfristige präventive Massnahmen getroffen werden. Zusammenfassend benötigen Mutter und häufig auch die Kinder aus hypertensiven Schwangerschaften geeignete kardiovaskuläre langfristige Präventionsmassnahmen. Frauen mit einem bislang nicht erkannten metabolischen bzw. Herz-Kreislauferkrankungsrisiko können damit einem sorgfältigen Follow-up zugeführt werden. Somit kann die hypertensive Schwangerschaft als Risikoindikator die Basis für eine frühzeitige Risikoprävention und ein gesundes Leben legen.

ABSTRACT The long-term inflammatory impact of diet could potentially elevate the risk of periodontal disease through modification of systemic inflammation. The aim of the present study was to prospectively investigate the associations between a food based, reduced rank regression (RRR) derived, empirical dietary inflammatory pattern (EDIP) and incidence of periodontitis. The study population was composed of 34,940 men from the Health Professionals Follow-Up Study, who were free of periodontal disease and major illnesses at baseline (1986). Participants provided medical and dental history through mailed questionnaires every 2 years, and dietary data through validated semi-quantitative food frequency questionnaires every 4 years. We used Cox proportional hazard models to examine the associations between EDIP scores and validated self-reported incidence of periodontal disease over a 24-year follow-up period. No overall association between EDIP and the risk of periodontitis was observed; the hazard ratio comparing the highest EDIP quintile (most proinflammatory diet) to the lowest quintile was 0.99 (95% confidence interval: 0.89 -1.10, p-value for trend = 0.97). A secondary analysis showed that among obese non-smokers (i.e. never and former smokers at baseline), the hazard ratio for periodontitis comparing the highest EDIP quintile to the lowest was 1.39 (95% confidence interval: 0.98 -1.96, p-value for trend = 0.03). In conclusion, no overall association was detected between EDIP and incidence of self-reported periodontitis in the study population. From the subgroups evaluated EDIP was significantly associated with increased risk of periodontitis only among nonsmokers who were obese. Hence, this association must be interpreted with caution.

Background: There is a need for identifying risk factors for hospitalization in Parkinson’s disease (PD) and also interventions to reduce acute hospital admission. Objective: To analyze the frequency, causes, and predictors of acute hospitalization (AH) in PD patients from a Spanish cohort. Methods: PD patients recruited from 35 centers of Spain from the COPPADIS-2015 (COhort of Patients with PArkinson’s DIsease in Spain, 2015) cohort from January 2016 to November 2017, were included in the study. In order to identify predictors of AH, Kaplan-Meier estimates of factors considered as potential predictors were obtained and Cox regression performed on time to hospital encounter 1-year after the baseline visit. Results: Thirty-five out of 605 (5.8%) PD patients (62.5±8.9 years old; 59.8% males) presented an AH during the 1-year follow-up after the baseline visit. Traumatic falls represented the most frequent cause of admission, being 23.7% of all acute hospitalizations. To suffer from motor fluctuations (HR [hazard ratio] 2.461; 95% CI, 1.065–5.678; p = 0.035), a very severe non-motor symptoms burden (HR [hazard ratio] 2.828; 95% CI, 1.319–6.063; p = 0.008), falls (HR 3.966; 95% CI 1.757–8.470; p = 0.001), and dysphagia (HR 2.356; 95% CI 1.124–4.941; p = 0.023) was associated with AH after adjustment to age, gender, disease duration, levodopa equivalent daily dose, total number of non-antiparkinsonian drugs, and UPDRS-IIIOFF. Of the previous variables, only falls (HR 2.998; 95% CI 1.080–8.322; p = 0.035) was an independent predictor of AH. Conclusion: Falls is an independent predictor of AH in PD patients.

Single Ventricle Palliation

Introduction: Single ventricle physiology management is challenging, especially in low-income countries. Objective: To report the palliation outcomes of single ventricle patients in a developing African country. Methods: We retrospectively studied 83 consecutive patients subjected to single ventricle palliation in a single center between March 2011 and December 2017. Preoperative data, surgical factors, postoperative results, and survival outcomes were analyzed. The patients were divided by palliation stage: I (pulmonary artery banding [PAB] or Blalock–Taussig shunt [BTS]), II (Glenn procedure), or III (Fontan procedure). Results: Of the 83 patients who underwent palliation (stages I-III), 38 deaths were observed (31 after stage I, six after stage II, and one after stage III) for an overall mortality of 45.7%. The main causes of operative mortality were multiple organ dysfunction due to sepsis, shunt occlusion, and cardiogenic shock. Twenty-eight survivors were lost to follow-up (22 after stage I, six after stage II). Thirteen stage II survivors are still waiting for stage III. The mean follow-up was 366 ± 369 days. Five-year survival was 28.4 % for PAB and 30.1% for BTS, while that for stage II and III was 49.8% and 57.1%, respectively. Age (hazard ratio, 0.61; 95% confidence interval: 0.47-0.7; P = .000) and weight at surgery (hazard ratio, 0.45; 95% confidence interval: 0.31-0.64; P = .002) impacted survival. Conclusion: A high-mortality rate was observed in this initial experience, mainly in stage I patients. A large number of patients were lost to follow-up. A task force to improve outcomes is urgently required.

Objective: Skeletal muscle dysfunction (sarcopenia) is an under-recognized complication of chronic kidney disease (CKD) that may have important clinical consequences. Gait speed is associated with sarcopenia and comorbid disease burden among older adults; however, little is known about the prognostic significance of gait speed in CKD. We determined the association of gait speed with all-cause mortality in a prospective cohort of non-dialysis CKD patients. Methods: We measured usual gait speed over 4-meters in 309 participants from a prospective study of non-dialysis CKD. Included subjects had an estimated glomerular filtration rate (eGFR ckdepi ) <90mL/min/1.73m 2 , were stroke-free and did not require a wheelchair for ambulation. Study coordinators assessed mortality during follow-up by phone contacts, medical record review, and the social security death index. We evaluated gait speed continuously, and using a cut point of 0.8 m/s, consistent with previous studies. We used Cox's proportional hazards to estimate the association of gait speed with mortality after adjustment for age, sex, race, smoking, diabetes, pre-existing CAD, BMI, eGFR and hemoglobin. Results: Median follow-up time was 2.7 years; range 27 days to 4.8 years. The mean age was 58.9 ± 13 years and mean eGFR by cystatin C (eGFR cysc ) was 48.5 ± 23mL/min/1.73m 2 . There were a total of 31 deaths (10.4%) during follow-up. Unadjusted mortality rates were 23 and 80 deaths per 1,000 person-years among participants who had a gait speed of >0.8m/s versus ≤0.8m/s, respectively. After full adjustment, gait speed ≤0.8m/s was associated with a 2.8-fold greater risk of death compared to a gait speed >0.8 m/s. Gait speed was also strongly associated with mortality when analyzed as a continuous variable ( Table ) and a stronger predictor of death than age, history of CAD, or diabetes. No. Deaths (%) Model 1 + Model 2 # Hazard Ratio 95% CI Hazard Ratio 95% CI Gait speed * 32(10) 0.74 (0.64-0.86) 0.75 (0.64-0.87) >0.8m/s 13 (6) Reference Reference ≤0.8m/s 19(19) 3.49 (1.54-7.95) 2.84 (1.25-6.48) * Gait speed analyzed continuously per 10cm/s increase in speed. +Model 1: Adjusted for age, sex, race, study site #Model 2: adds smoking, BMI, eGFR cysc , diabetes, prevalent coronary disease.

Aims. This study aimed at assessing the impact of baseline bilirubin (TBiL) on the incidence of diabetic retinopathy (DR) based on a five-year cohort study which consisted of 5323 Chinese male diabetic patients.Methods. A cohort study based on 5323 male diabetic patients was conducted in Beijing, from 2009 to 2013. Both baseline TBiL and follow-up changes were measured. Cox proportional risk model was used to calculate the hazard ratio (HR) of TBiL for DR risk.Results. During the follow-up period, there were 269 new DR cases. The incidence of five-year follow-up was 5.1% (95% CI: 4.5%~5.6%). The TBiL level of those who had diabetic retinopathy was lower than that of those without (12.51+ 1.20 mol/L and 13.11+ 1.32μmol/L,P=0.033). And more interestingly, along with the quintiles of baseline TBiL, there showed a U-shaped curve with DR incidence. And the RRs were 0.928 (95% CI: 0.646–1.331), 0.544 (95% CI: 0.365–0.811), 0.913 (95% CI: 0.629–1.324), and 1.035 (95% CI: 0.725–1.479) for the second, third, fourth, and fifth quintiles of baseline TBiL levels, respectively, compared with the first quintile. For follow-up TBiL changes, after being adjusted for related covariables and baseline TBiL levels (as continuous variable) in the model, the RRs for DR were 1.411 (95% CI: 1.081–1.842) for those who had decreased TBiL level and 0.858 (95% CI: 0.770–0.947) for those who had increased TBiL level during follow-up. And this association was more prominent among those with lower baseline TBiL level.Conclusions. Serum TBiL had a U-shaped relationship with DR incidence, which was independent of control status of diabetes and other related covariates.

The prevalence of idiopathic pulmonary fibrosis (IPF), a fatal and progressive lung disease, is estimated at 1.25–63 out of 100 000, making large population studies difficult. Recently, the need for large longitudinal registries to study IPF has been recognised.The Australian IPF Registry (AIPFR) is a national registry collating comprehensive longitudinal data of IPF patients across Australia. We explored the characteristics of this IPF cohort and the effect of demographic and physiological parameters and specific management on mortality.Participants in the AIPFR (n=647, mean age 70.9±8.5 years, 67.7% male, median follow up 2 years, range 6 months–4.5 years) displayed a wide range of age, disease severity and co-morbidities that is not present in clinical trial cohorts. The cumulative mortality rate in year one, two, three and four was 5%, 24%, 37% and 44% respectively. Baseline lung function (forced vital capacity, diffusing capacity of the lung for carbon monoxide, composite physiological index) and GAP (gender, age, physiology) stage (hazard ratio 4.64, 95% CI 3.33–6.47, p<0.001) were strong predictors of mortality. Patients receiving anti-fibrotic medications had better survival (hazard ratio 0.56, 95% CI 0.34–0.92, p=0.022) than those not on anti-fibrotic medications, independent of underlying disease severity.The AIPFR provides important insights into the understanding of the natural history and clinical management of IPF.

Aims It is well known that a decline in physical activity is associated with an increase of all-cause death including cardiovascular events and cancer. Few studies have examined the association between occupational sitting time and mortality. Therefore, we investigated this issue in a general population. Methods Physical activity and occupational sitting time were measured using the Baecke physical activity questionnaire in 1999. The questionnaire generated indices in three physical activity categories: work, sport and leisure-time. A total physical activity index was calculated by adding these three indices. The Baecke physical activity questionnaire was able to evaluate occupational sitting time. Hazard ratios and 95% confidence intervals (CIs) were calculated using Cox's proportional hazard regression models. Results We enrolled a total of 1680 participants, who were followed up for 15.9 ± 3.8 years. The final follow-up rate was 93%. During the follow-up period, 397 subjects died. A significant inverse association ( p < 0.0001) was found between physical activity and mortality after adjustment for age and sex. Compared with lower levels of physical activity, the adjusted hazard ratio for mortality at higher levels of physical activity was 0.85 (95% CI: 0.78–0.92). Longer occupational sitting time was also significantly associated with higher mortality ( p < 0.01). The adjusted hazard ratio for mortality at longer occupational sitting time was 1.16 (95% CI: 1.05–1.27). These findings were observed in males, but not in females. Conclusions Our data demonstrated that higher levels of physical activity are associated with a reduced risk of cancer and cardiovascular death. Further, longer occupational sitting time is associated with increased mortality.

Abstract BACKGROUND Endovascular treatment of intracranial aneurysms is associated with higher rates of recurrence and retreatment, though contemporary rates and risk factors for basilar tip aneurysms (BTAs) are less well-described. OBJECTIVE To characterize progression, retreatement, and retreated progression of BTAs treated with microsurgical or endovascular interventions. METHODS We retrospectively reviewed records for 141 consecutive BTA patients. We included 158 anterior communicating artery (ACoA) and 118 middle cerebral artery (MCA) aneurysms as controls. Univariate and multivariate analyses were used to calculate rates of progression (recurrence of previously obliterated aneurysms and progression of known residual aneurysm dome or neck), retreatment, and retreated progression. Kaplan–Meier analysis was used to characterize 24-mo event rates for primary outcome prediction. RESULTS Of 141 BTA patients, 62.4% were ruptured and 37.6% were unruptured. Average radiographical follow-up was 33 mo. Among ruptured aneurysms treated with clipping, there were 2 rehemorrhages due to recurrence (6.1%), and none in any other cohorts. Overall rates of progression (28.9%), retreatment (28.9%), and retreated progression (24.7%) were not significantly different between surgical and endovascular subgroups, though ruptured aneurysms had higher event rates. Multivariate modeling confirmed rupture status (P = .003, hazard ratio = 0.14) and aneurysm dome width (P = .005, hazard ratio = 1.23) as independent predictors of progression requiring retreatment. In a separate multivariate analysis with ACoA and MCA aneurysms, basilar tip location was an independent predictor of progression, retreatment, and retreated progression. CONCLUSION BTAs have higher rates of progression and retreated progression than other aneurysm locations, independent of treatment modality. Rupture status and dome width are risk factors for progression requiring retreatment.
