Energiaverotuet ja kustannustehokas huoltovarmuus

Tässä hankkeessa on selvitetty, ovatko lämmityspolttoaineiden verotuet tehokkaita keinoja energian huoltovarmuuden ja sähkön toimitusvarmuuden varmistamiseksi, ja olisiko huoltovarmuuteen ja sähkön toimitusvarmuuteen liittyvät tavoitteet mahdollista saavuttaa tehokkaammin muilla tavoin. Tarkasteltavat verotuet ovat turpeen normia alempi verokanta, yhdistetyn tuotannon (CHP) verotuki ja kiinteän biomassan verottomuus. Lyhyellä aikajänteellä (noin 1–2 vuotta) turpeen verotuen poisto johtaisi turpeen käytön vähentymiseen ja korvaamiseen kiinteällä biomassalla, sekä kotimaisella että ulkomaisella. Pidemmällä aikavälillä (vuoteen 2030 mennessä) turpeen verotuen poisto johtaisi todennäköisesti turpeen käytön loppumiseen. Tämä asettaisi haasteita huoltovarmuudelle, mutta siihen voitaisiin vastata varastoimalla biomassaa tai kevyttä polttoöljyä. Vastaavasti CHP:n verotuen poisto johtaisi maakaasukäyttöisen kapasiteetin ennenaikaiseen sulkemiseen noin 500 MW:n verran. Biomassan verotuen poiston ei havaittu tukevan investointeja biomassakäyttöiseen CHP-kapasiteettiin. Kaikkien verotukien poisto johtaisi kaukolämmön tuotantokustannusten kasvuun, kaukolämmön hinnan nousuun ja samalla kiinteistökohtaisten lämpöpumppujen kilpailukyvyn parantumiseen. Siten verotukien poiston merkittävä vaikutus on lämmityksen kiihtyvä sähköistyminen. Tämä saattaisi heikentää sähkön huippukulutuksen aikaista tehotasetta ja asettaisi haasteita sähkön huolto- ja toimitusvarmuudelle.

Including Information on Overdiagnosis in Shared Decision Making : A Review of Prostate Cancer Screening Decision Aids

Publisher Copyright: © The Author(s) 2022.Background. Overdiagnosis is an accepted harm of cancer screening, but studies of prostate cancer screening decision aids have not examined provision of information important in communicating the risk of overdiagnosis, including overdiagnosis frequency, competing mortality risk, and the high prevalence of indolent cancers in the population. Methods. We undertook a comprehensive review of all publicly available decision aids for prostate cancer screening, published in (or translated to) the English language, without date restrictions. We included all decision aids from a recent systematic review and screened excluded studies to identify further relevant decision aids. We used a Google search to identify further decision aids not published in peer reviewed medical literature. Two reviewers independently screened the decision aids and extracted information on communication of overdiagnosis. Disagreements were resolved through discussion or by consulting a third author. Results. Forty-one decision aids were included out of the 80 records identified through the search. Most decision aids (n = 32, 79%) did not use the term overdiagnosis but included a description of it (n = 38, 92%). Few (n = 7, 17%) reported the frequency of overdiagnosis. Little more than half presented the benefits of prostate cancer screening before the harms (n = 22, 54%) and only 16, (39%) presented information on competing risks of mortality. Only 2 (n = 2, 5%) reported the prevalence of undiagnosed prostate cancer in the general population. Conclusion. Most patient decision aids for prostate cancer screening lacked important information on overdiagnosis. Specific guidance is needed on how to communicate the risks of overdiagnosis in decision aids, including appropriate content, terminology and graphical display. Most patient decision aids for prostate cancer screening lacks important information on overdiagnosis. Specific guidance is needed on how to communicate the risks of overdiagnosis.Peer reviewe

Robot-assisted versus three-dimensional laparoscopic radical prostatectomy : 12-month outcomes of a randomised controlled trial

Objectives: To compare functional and oncological outcomes of robot-assisted laparoscopic prostatectomy (RALP) to three-dimensional laparoscopic radical prostatectomy (3D-LRP) at 12 months after surgery. Patients and methods: Prospective randomised single-centre study of 145 consecutive men referred to radical prostatectomy in a tertiary referral centre in Finland. Patients were randomised 1:1 to the RALP (N = 75) and 3D-LRP (N = 70) groups. The primary outcome was urinary continence evaluated with the Expanded Prostate Cancer Index Composite 26-item version (EPIC-26) incontinence domain score at 12 months after surgery. Secondary outcomes included the use of protective pads at 12 months after surgery, EPIC-26 domain scores of irritative/obstructive, bowel, sexual and hormonal symptoms, positive surgical margin (PSM) rate, and biochemical recurrence (BCR). Complication frequency within the 3-month period after surgery was evaluated according to Clavien–Dindo classification. Statistical significance between groups was analysed using Mann–Whitney, chi-square and Fisher's exact tests. The trial was terminated after interim analysis based on no statistically significant difference in EPIC-26 urinary incontinence domain scores. Altogether 145 patients of the target accrual of 280 patients were recruited. Results: Postoperative continence at 12 months after surgery according to the EPIC-26 incontinence domain was 79.25 in both groups (P = 0.4). Between group difference was −5.8 (95% confidence interval –15.2 to 3.6). There was no statistically significant difference in the rates of PSM or BCR between the two surgical modality groups. Conclusion: We were unable to demonstrate a difference between the RALP and 3D-LRP groups for functional and oncological outcomes at 12 months after surgery.Peer reviewe

Colonic Delivery of α-Linolenic Acid by an Advanced Nutrient Delivery System Prolongs Glucagon-Like Peptide-1 Secretion and Inhibits Food Intake in Mice

ScopeNutrients stimulate the secretion of glucagon-like peptide-1 (GLP-1), an incretin hormone, secreted from enteroendocrine L-cells which decreases food intake. Thus, GLP-1 analogs are approved for the treatment of obesity, yet cost and side effects limit their use. L-cells are mainly localized in the distal ileum and colon, which hinders the utilization of nutrients targeting GLP-1 secretion. This study proposes a controlled delivery system for nutrients, inducing a prolonged endogenous GLP-1 release which results in a decrease food intake.Methods and Resultsα-Linolenic acid (αLA) was loaded into thermally hydrocarbonized porous silicon (THCPSi) particles. In vitro characterization and in vivo effects of αLA loaded particles on GLP-1 secretion and food intake were studied in mice. A total of 40.4 ± 3.2% of loaded αLA is released from particles into biorelevant buffer over 24 h, and αLA loaded THCPSi significantly increased in vitro GLP-1 secretion. Single-dose orally given αLA loaded mesoporous particles increased plasma active GLP-1 levels at 3 and 4 h and significantly reduced the area under the curve of 24 h food intake in mice.ConclusionsαLA loaded THCPSi particles could be used to endogenously stimulate sustain gastrointestinal hormone release and reduce food intake.</p

Randomised double-blind phase 3 clinical study testing impact of atorvastatin on prostate cancer progression after initiation of androgen deprivation therapy : study protocol

Introduction Blood cholesterol is likely a risk factor for prostate cancer prognosis and use of statins is associated with lowered risk of prostate cancer recurrence and progression. Furthermore, use of statins has been associated with prolonged time before development of castration resistance (CR) during androgen deprivation therapy (ADT) for prostate cancer. However, the efficacy of statins on delaying castration-resistance has not been tested in a randomised placebo-controlled setting. This study aims to test statins' efficacy compared to placebo in delaying development of CR during ADT treatment for primary metastatic or recurrent prostate cancer. Secondary aim is to explore effect of statin intervention on prostate cancer mortality and lipid metabolism during ADT. Methods and analysis In this randomised placebo-controlled trial, a total of 400 men with de novo metastatic prostate cancer or recurrent disease after primary treatment and starting ADT will be recruited and randomised 1:1 to use daily 80 mg of atorvastatin or placebo. All researchers, study nurses and patients will be blinded throughout the trial. Patients are followed until disease recurrence or death. Primary outcome is time to formation of CR after initiation of ADT. Serum lipid levels (total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) and trigyserides) are analysed to test whether changes in serum cholesterol parameters during ADT predict length of treatment response. Furthermore, the trial will compare quality of life, cardiovascular morbidity, changes in blood glucose and circulating cell-free DNA, and urine lipidome during trial. Ethics and dissemination This study is approved by the Regional ethics committees of the Pirkanrnaa Hospital District, Science centre, Tampere, Finland (R18065M) and Tarto University Hospital, Tarto, Estonia (319/T-6). All participants read and sign informed consent form before study entry. After publication of results for the primary endpoints, anonymised summary metadata and statistical code will be made openly available. The data will not include any information that could make it possible to identify a given participant.Peer reviewe

Decision Aids for Prostate Cancer Screening Choice: A Systematic Review and Meta-analysis

Key PointsQuestionWhat is the association of decision aids vs usual care with shared decision-making in men deciding whether to undergo prostate cancer screening? FindingsThis systematic review and meta-analysis of 19 randomized clinical trials comparing decision aids for prostate cancer screening (12781 men) found that decision aids are probably associated with a small reduction in decisional conflict and are possibly associated with an increase in knowledge. Decision aids are possibly not associated with whether physicians and patients discuss prostate cancer screening and are possibly not associated with actual screening decisions. MeaningRandomized clinical trials have failed to provide compelling evidence for the use of decision aids for men contemplating prostate cancer screening that have, up to now, undergone rigorous testing to determine their outcome. ImportanceUS guidelines recommend that physicians engage in shared decision-making with men considering prostate cancer screening. ObjectiveTo estimate the association of decision aids with decisional outcomes in prostate cancer screening. Data SourcesMEDLINE, Embase, PsycINFO, CINAHL, and Cochrane CENTRAL were searched from inception through June 19, 2018. Study SelectionRandomized trials comparing decision aids for prostate cancer screening with usual care. Data Extraction and SynthesisIndependent duplicate assessment of eligibility and risk of bias, rating of quality of the decision aids, random-effects meta-analysis, and Grading of Recommendations, Assessment, Development and Evaluations rating of the quality of evidence. Main Outcomes and MeasuresKnowledge, decisional conflict, screening discussion, and screening choice. ResultsOf 19 eligible trials (12781 men), 9 adequately concealed allocation and 8 blinded outcome assessment. Of 12 decision aids with available information, only 4 reported the likelihood of a true-negative test result, and 3 presented the likelihood of false-negative test results or the next step if the screening test result was negative. Decision aids are possibly associated with improvement in knowledge (risk ratio, 1.38; 95% CI, 1.09-1.73; I-2=67%; risk difference, 12.1; low quality), are probably associated with a small decrease in decisional conflict (mean difference on a 100-point scale, -4.19; 95% CI, -7.06 to -1.33; I-2=75%; moderate quality), and are possibly not associated with whether physicians and patients discuss prostate cancer screening (risk ratio, 1.12; 95% CI, 0.90-1.39; I-2=60%; low quality) or with men's decision to undergo prostate cancer screening (risk ratio, 0.95; 95% CI, 0.88-1.03; I-2=36%; low quality). Conclusions and RelevanceThe results of this study provide moderate-quality evidence that decision aids compared with usual care are associated with a small decrease in decisional conflict and low-quality evidence that they are associated with an increase in knowledge but not with whether physicians and patients discussed prostate cancer screening or with screening choice. Results suggest that further progress in facilitating effective shared decision-making may require decision aids that not only provide education to patients but are specifically targeted to promote shared decision-making in the patient-physician encounter. This systematic review and meta-analysis of 19 randomized clinical trials estimates the association of decision aids with decisional outcomes in prostate cancer screening.Peer reviewe

Detection of Prostate Cancer Using Biparametric Prostate MRI, Radiomics, and Kallikreins : A Retrospective Multicenter Study of Men With a Clinical Suspicion of Prostate Cancer

Background Accurate detection of clinically significant prostate cancer (csPCa), Gleason Grade Group >= 2, remains a challenge. Prostate MRI radiomics and blood kallikreins have been proposed as tools to improve the performance of biparametric MRI (bpMRI). Purpose To develop and validate radiomics and kallikrein models for the detection of csPCa. Study Type Retrospective. Population A total of 543 men with a clinical suspicion of csPCa, 411 (76%, 411/543) had kallikreins available and 360 (88%, 360/411) did not take 5-alpha-reductase inhibitors. Two data splits into training, validation (split 1: single center, n = 72; split 2: random 50% of pooled datasets from all four centers), and testing (split 1: 4 centers, n = 288; split 2: remaining 50%) were evaluated. Field strength/Sequence A 3 T/1.5 T, TSE T2-weighted imaging, 3x SE DWI. Assessment In total, 20,363 radiomic features calculated from manually delineated whole gland (WG) and bpMRI suspicion lesion masks were evaluated in addition to clinical parameters, prostate-specific antigen, four kallikreins, MRI-based qualitative (PI-RADSv2.1/IMPROD bpMRI Likert) scores. Statistical Tests For the detection of csPCa, area under receiver operating curve (AUC) was calculated using the DeLong's method. A multivariate analysis was conducted to determine the predictive power of combining variables. The values of P-value < 0.05 were considered significant. Results The highest prediction performance was achieved by IMPROD bpMRI Likert and PI-RADSv2.1 score with AUC = 0.85 and 0.85 in split 1, 0.85 and 0.83 in split 2, respectively. bpMRI WG and/or kallikreins demonstrated AUCs ranging from 0.62 to 0.73 in split 1 and from 0.68 to 0.76 in split 2. AUC of bpMRI lesion-derived radiomics model was not statistically different to IMPROD bpMRI Likert score (split 1: AUC = 0.83, P-value = 0.306; split 2: AUC = 0.83, P-value = 0.488). Data Conclusion The use of radiomics and kallikreins failed to outperform PI-RADSv2.1/IMPROD bpMRI Likert and their combination did not lead to further performance gains.

The Impact of Nocturia on Mortality: A Systematic Review and Meta-Analysis

Purpose: Nocturia (waking from sleep at night to void) is a common cause of sleep disruption associated with increased comorbidity and impaired quality of life. However, its impact on mortality remains unclear. We performed a systematic review and meta-analysis to evaluate the association of nocturia with mortality as a prognostic factor and a causal risk factor. Materials and Methods: We searched PubMed (R), Scopus (R), CINAHL (R) (Cumulative Index of Nursing and Allied Health Literature) and major conference abstracts up to December 31, 2018. Random effects meta-analyses were done to address the adjusted RR of mortality in people with nocturia. Metaregression was performed to explore potential determinants of heterogeneity, including the risk of bias. We applied the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) framework to rate the quality of evidence for nocturia as a prognostic risk factor for mortality and separately as a cause of mortality. Results: Of the 5,230 identified reports 11 observational studies proved eligible for inclusion. To assess nocturia 10 studies used symptom questionnaires and 1 used frequency-volume charts. Nocturia was defined as 2 or more episodes per night in 6 studies (55%) and as 3 or more episodes per night in 5 (45%). Pooled estimates demonstrated a RR of 1.27 (95% CI 1.16-1.40, I-2=48%) with an absolute 1.6% and 4.0% 5-year mortality difference in individuals 60 and 75 years old, respectively. The pooled estimates of relative risk did not differ significantly across varying age, gender, followup, nocturia case definition, risk of bias or study region. We rated the quality of evidence for nocturia as a prognostic factor as moderate and as a cause of mortality as very low. Conclusions: Nocturia is probably associated with an approximately 1.3-fold increased risk of death.Peer reviewe
