Changes in operative treatment of tibia fractures in Finland between 2000 and 2018: A nationwide study

Introduction:Incidences of different tibia fractures are not well reported. Possible changes in the operative treatment methods have also not been studied. The aim of this nationwide registry study is to determine the incidence of operatively treated tibia fractures and investigate the possible changes in treatment methods in Finland between 2000 and 2018.Methods:All patients aged 16 years or older with operatively treated tibia fractures in Finland from 2000 to 2018 were included. The incidence of operatively treated proximal, diaphyseal, and distal tibia fractures per 100,000 person years by age, sex, mechanism of injury, and study year was calculated. Data were extracted from the Finnish National Hospital Discharge Register.Results:A total of 5996 proximal, 6874 diaphyseal, and 5658 distal tibia fractures were reported during the 18-year study period, resulting in incidences of 7.2/100,000, 8.1/100,000, and 6.9/100,000 person years for operatively treated proximal, diaphyseal, and distal tibia fractures, respectively. Over the study period, a clear change in fixation method in distal tibia fractures was found as plating became popular in the beginning of the 21st century. During the last 5 years of the study period, nailing and plating were equally used.Conclusions:Operatively treated proximal tibia fractures are most common among older females while diaphyseal fractures are most frequent in young male patients. Distal tibia fractures occur most often among middle-aged people.</p

Nighttime ambulatory pulse pressure predicts cardiovascular and all-cause mortality among middle-aged participants in the 21-year follow-up

Office pulse pressure (PP) is a predictor for cardiovascular (CV) events and mortality. Our aim was to evaluate ambulatory PP as a long-term risk factor in a random cohort of middle-aged participants. The Opera study took place in years 1991-1993, with a 24-h ambulatory blood pressure measurement (ABPM) performed to 900 participants. The end-points were non-fatal and fatal CV events, and deaths of all-causes. Follow-up period, until the first event or until the end of the year 2014, was 21.1 years (mean). Of 900 participants, 22.6% died (29.6% of men/15.6% of women, p<.001). A CV event was experienced by 208 participants (23.1%), 68.3% of them were male (p<.001). High nighttime ambulatory PP predicted independently CV mortality (hazard ratio [HR] 2.60; 95% confidence interval [CI 95%] 1.08-6.31, p=.034) and all-cause mortality in the whole population (HR 1.72; Cl 95% 1.06-2.78, p=.028). In males, both 24-h PP and nighttime PP associated with CV mortality and all-cause mortality (24-h PP HR for CV mortality 2.98; CI 95% 1.11-8.04, p=.031 and all-cause mortality HR 2.40; CI 95% 1.32-4.37, p=.004). Accordingly, nighttime PP; HR for CV mortality 3.13; CI 95% 1.14-8.56, p=.026, and for all-cause mortality HR 2.26; CI 95% 1.29-3.96, p=.004. Cox regression analyses were adjusted by sex, CV risk factors, and appropriate ambulatory mean systolic BP. In our study, high ambulatory nighttime PP was detected as a long-term risk factor for CV and all-cause mortality in middle-aged individuals

Expression of Androgen Receptor Splice Variants in Prostate Cancer Bone Metastases is Associated with Castration-Resistance and Short Survival

Background: Constitutively active androgen receptor variants (AR-V) lacking the ligand binding domain (LBD) may promote  the development of castration-resistant prostate cancer (CRPC). The expression of AR-Vs in the clinically most important metastatic site, the bone, has, however, not been well documented. Our aim was therefore to compare levels of AR-Vs in hormone-naive (HN) and CRPC bone metastases in comparison to primary PC and non-malignant prostate tissue, as well as in relation to AR protein expression, whole-genome transcription profiles and patient survival. Methodology/Principal Findings: Hormone-naı¨ve (n = 10) and CRPC bone metastases samples (n = 30) were obtained from  40 patients at metastasis surgery. Non-malignant and malignant prostate samples were acquired from 13 prostatectomized men. Levels of full length AR (ARfl) and AR-Vs termed AR-V1, AR-V7, and AR-V567es mRNA were measured with RT-PCR and whole-genome transcription profiles with an Illumina Beadchip array. Protein levels were examined by Western blotting and immunohistochemistry. Transcripts for ARfl, AR-V1, and AR-V7 were detected in most primary tumors and metastases, and levels were significantly increased in CRPC bone metastases. The AR-V567es transcript was detected in 23% of the CRPC bone metastases only. A sub-group of CRPC bone metastases expressed LBD-truncated AR proteins at levels comparable to the ARfl. Detectable AR-V567es and/or AR-V7 mRNA in the upper quartile, seen in 1/3 of all CRPC bone metastases, was associated with a high nuclear AR immunostaining score, disturbed cell cycle regulation and short survival. Conclusions/Significance: Expression of AR-Vs is increased in CRPC compared to HN bone metastases and associated with a particularly poor prognosis. Further studies are needed to test if patients expressing such AR-Vs in their bone metastases benefit more from drugs acting on or down-stream of these AR-Vs than from therapies inhibiting androgen synthesis

Impact of chronic obstructive pulmonary disease on short-term outcome in patients with ST-elevation myocardial infarction during COVID-19 pandemic: insights from the international multicenter ISACS-STEMI registry

Background Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study. Methods In the ISACS-STEMI COVID-19 registry we included retrospectively patients with STEMI treated with primary percutaneous coronary intervention (PCI) between March and June of 2019 and 2020 from 109 high-volume primary PCI centers in 4 continents. Results A total of 15,686 patients were included in this analysis. Of them, 810 (5.2%) subjects had a COPD diagnosis. They were more often elderly and with a more pronounced cardiovascular risk profile. No preminent procedural dissimilarities were noticed except for a lower proportion of dual antiplatelet therapy at discharge among COPD patients (98.9% vs. 98.1%, P = 0.038). With regards to short-term fatal outcomes, both in-hospital and 30-days mortality occurred more frequently among COPD patients, similarly in pre-COVID-19 and COVID-19 era. However, after adjustment for main baseline differences, COPD did not result as independent predictor for in-hospital death (adjusted OR [95% CI] = 0.913[0.658-1.266], P = 0.585) nor for 30-days mortality (adjusted OR [95% CI] = 0.850 [0.620-1.164], P = 0.310). No significant differences were detected in terms of SARS-CoV-2 positivity between the two groups. Conclusion This is one of the largest studies investigating characteristics and outcome of COPD patients with STEMI undergoing primary angioplasty, especially during COVID pandemic. COPD was associated with significantly higher rates of in-hospital and 30-days mortality. However, this association disappeared after adjustment for baseline characteristics. Furthermore, COPD did not significantly affect SARS-CoV-2 positivity. Trial registration number: NCT 04412655 (2nd June 2020)

Cardiovascular autonomic regulation in systemic hypertension

Abstract Neurogenic factors are known to be important in the development of hypertension. Our current knowledge of the role of autonomic nervous system in chronic hypertension is, however, limited. The purpose of the present study was to evaluate the possible abnormalities in heart rate variability (HRV) and baroreflex sensitivity (BRS) in patients with long standing systemic hypertension compared to subjects without evidence of cardiovascular disease. A particular aim was also to examine whether genetic variation in the renin-angiotensin-aldosterone system (RAS) genes have an influence on cardiovascular autonomic regulation. Case-control studies were carried out on a total of 280 normotensive and 214 hypertensive subjects drawn from a random middle-aged population originally recruited for an epidemiologic study of cardiovascular risk factors. The possible association of BRS with the genetic polymorphisms of renin-angiotensin-aldosterone system genes was studied in a cross-sectional study of 315 healthy controls. Genetic associations were also tested in a younger, independent population sample of 66 subjects. The effects of intensified antihypertensive treatment on autonomic cardiovascular control were evaluated in 33 hypertensive patients with poor blood pressure control. Wide interindividual variation in both HRV and BRS was observed in normotensive as well as hypertensive subjects. Overall HRV and autonomic responses to a change in body posture were blunted in long-standing hypertension. Decreased HRV was mainly related to elevated blood pressure and obesity. For the first time in a population-based study, it was confirmed that BRS is impaired in patients with long-standing hypertension despite adequate antihypertensive treatment. In contrast to HRV, BRS was reduced in hypertensive subjects also after adjustment for blood pressure and obesity. BRS also varied widely both between healthy and hypertensive individuals. The wide interindividual variation in the markers of autonomic cardiovascular regulation was not, however, completely explained by demographic variables, cardiovascular risk factors or lifestyle, suggesting a genetic component contributing to HRV and BRS. The polymorphism in the aldosterone synthase (CYP11B2) gene was found to strongly associate with BRS in two independent random populations of apparently healthy subjects. The association was even stronger in the younger population. On the basis of the observations made in the older population, it seems possible that women are protected against the effect of age and blood pressure on BRS and tend to maintain the genomic influence longer. Intensified antihypertensive combination therapy improved blood pressure control and caused regression of left ventricular hypertrophy, and resulted in significant improvements of HRV and BRS. The present study shows that HRV and BRS are altered in long-standing systemic hypertension. Together with age, blood pressure and obesity, genetic factors seem to be important determinants of BRS. However, abnormal autonomic cardiovascular regulation does not seem to be an irreversible phenomenon, but can be partly restored by modern combination antihypertensive therapy

Primary healthcare managers’ perceptions of management competencies at different management levels in digital health services:secondary analysis

Abstract Purpose: The purpose of this study is to describe primary health-care managers’ perceptions of management competencies at different management levels in digital health services using the management competency assessment program as a framework. Design/methodology/approach: A secondary analysis study involving 21 semi-structured individual interviews was conducted among Finnish primary health-care managers at different management levels (frontline, middle and senior). The deductive framework method was used to analyze the data. Findings: Similarities and differences were found in management competencies between different levels of management. Competencies related to the use of digitalization were highlighted by managers at all management levels. Managers at all management levels were involved in developing digital solutions and supporting employees in using digital solutions in their work. Frontline and middle managers emphasized more issues related to day-to-day management and communication with employees, whereas senior managers highlighted the management of large entities. Research limitations/implications: In the secondary analysis, data were used for purposes other than originally intended. Therefore, the data are subject to limitations of the methodology applied and should be transferred to other contexts with caution. Practical implications: Identifying the management competencies needed to manage digital health services is important to target managers’ training according to needs in the future. Social implications: The results could be used to develop the management of digital health services, as well as improve digital health services and their deployment. Originality/value: Previous literature mostly examined managers’ informatics competencies and paid little attention to other management competencies. This study discusses more broadly the management competencies that digital health services require from managers at different levels of management

Cox regression analyses were adjusted by sex, CV risk factors, and appropriate ambulatory mean systolic BP. In our study, high ambulatory nighttime PP was detected as a long-term risk factor for CV and all-cause mortality in middle-aged individuals

Smoking cessation and obesity-related morbidities and mortality in a 20-year follow-up study

Abstract Background: Smoking is the biggest preventable factor causing mortality and morbidity and the health benefits of smoking cessation are commonly known. Smoking cessation-related weight gain is well documented. We evaluated the association between smoking cessation and the incidence of obesity-related morbidities such as hypertension, diabetes and metabolic syndrome as well as mortality. We also evaluated telomere length related to smoking cessation. Material and methods: This study was part of the OPERA (Oulu Project Elucidating Risk of Atherosclerosis) study. The mean follow up time among the 600 study subjects was 20 years. We divided the study subjects into four groups by smoking status (“never”, “current”, “ex-smokers” and “quit”) and analyzed their health status. “Ex-smokers” had quit smoking before baseline and “quit” quit during the follow-up time. Information about total mortality between the years 2013–2020 was also utilized. Results: During the follow-up time systolic blood pressure decreased the most in the “current” and in the “ex-smoker” groups. Office SBP decreased the least in the “quit” group (p = 0.001). BMI increased the most in the “quit” and the least in the “ex-smokers” group (p = 0.001). No significant increases were seen in the incidence of obesity-related-diseases, such as metabolic syndrome, hypertension and diabetes was seen. There was no significant difference in the shortening of telomeres. Odds of short-term mortality was increased in the “current” group (2.43 (CI 95% 1.10; 5.39)), but not in the “quit” (1.43 (CI 95% 0.73–2.80)) or “ex-smoker” (1.02 (CI 95% 0.56–1.86)) groups when compared to “never” group. Conclusions: Even though, the blood pressure levels were unfavorable in the “quit” group, there was no significant increase in the incidence of obesity-related-diseases, and a noticeable benefit in short-term mortality was seen during the 6-year follow-up. The benefits of smoking cessation outweigh the disadvantages in the long-term

MANTA versus ProGlide vascular closure devices in transfemoral transcatheter aortic valve implantation

Abstract Background: The MANTA system is a novel vascular closure device (VCD) and its safety and efficacy were compared to the ProGlide VCD in patients undergoing transfemoral transcatheter aortic valve implantation (TAVI). Methods: This is a retrospective study including 222 patients who underwent transfemoral TAVI at three Finnish University Hospitals. The MANTA VCD was used in 107 patients and their outcome was compared with that of 115 patients in whom the arterial access was closed with the ProGlide VCD. Results: VARC-2 VCD failure occurred less frequently in the MANTA cohort (3.7% vs. 7.8%, p = 0.378), but the difference did not reach statistical significance. When adjusted for the introducer outer diameter, the MANTA cohort had similar rates of VARC-2 major vascular complications (9.3% vs. 12.2%, adjusted: p = 0.456), VARC-2 life-threatening/disabling bleeding (9.3% vs. 6.1%, adjusted: p = 0.296) and need of invasive treatment of bleeding (4.7% vs. 7.0%, adjusted: p = 0.416) compared to the ProGlide cohort. Additional VCDs were more frequently needed in the ProGlide cohort (58.3% vs. 1.9%, p < 0.0001). Conclusions: In patients undergoing transfemoral TAVI, the MANTA VCD showed a similar risk of VARC-2 vascular and bleeding complications compared to the ProGlide VCD, but it reduced significantly the need of additional VCDs for completion of hemostasis
