ABSTRACT
BACKGROUND: Potential regional differences in cancer incidence and survival would demand targeted interventions to decrease cancer related death. METHODS: This descriptive cohort study provides an overview of regional cancer incidence and relative survival (RS) in Denmark during 2007-2021. National cancer incidence and RS estimates were calculated similar to the official statistics for the Danish Cancer Registry. Specifically, we estimated age-standardized (World) cancer incidence rates (ASR), and RS in 3-year periods by sex, and the five regions of Denmark (i.e., Region of Northern Denmark, Central Denmark Region, Region of Southern Denmark, Region Zealand, and Capital Region). RESULTS: We identified 578,107 incident cancers in Denmark during 2007-2021, of which 124 123 were diagnosed in 2019-2021. Small fluctuations were seen in ASR for cancer overall in all five regions during 2007-2018, followed by decreasing trends in 2019-2021. Men exhibited higher ASRs than women. Consistent improvements in 1- and 5-year RS were seen during the study period in all regions. However, for patients diagnosed in 2019-2021, the 5-year RS levelled off. These patients experienced 1-year RS of 83â¯% among men and 84â¯% among women, and the 5-year RS was also similar between sexes (men: 67â¯%, women: 70â¯%, overall: 68â¯%). Region Zealand generally presented lower RS estimates for both sexes combined. CONCLUSION: Cancer survival improved between 2007 and 2021 in all Danish regions for both sexes. However, the improvements in cancer survival appeared to have levelled off in the most recent period, 2019-2021. For both sexes, the lowest survival was suggested for Region Zealand.

Background: In a population-based setting, we investigated the risks of testing positive for SARS-CoV-2 and developing severe COVID-19 outcomes among cancer patients compared with the general population. Methods: In nationwide cohorts, we identified all individuals in Norway, Denmark and Iceland who tested positive for SARS-CoV-2 or had a severe COVID-19 outcome (hospitalisation, intensive care, and death) from March until December 2020, using data from national health registries. We estimated standardised incidence ratios (SIRs) with 95% confidence intervals (CIs) comparing cancer patients with the general population. Findings: During the first wave of the pandemic, cancer patients in Norway and Denmark had higher risks of testing SARS-CoV-2 positive compared to the general population. Throughout 2020, recently treated cancer patients were more likely to test SARS-CoV-2 positive. In Iceland, cancer patients experienced no increased risk of testing positive. The risk of COVID-19-related hospitalisation was higher among cancer patients diagnosed within one year of hospitalisation (Norway: SIR = 2.43, 95% CI 1.89-3.09; Denmark: 2.23, 1.96-2.54) and within five years (Norway: 1.58, 1.35-1.83; Denmark: 1.54, 1.42-1.66). Risks were higher in recently treated cancer patients and in those diagnosed with haematologic malignancies, colorectal or lung cancer. Risks of COVID-19-related intensive care and death were higher among cancer patients. Interpretation: Cancer patients were at increased risk of testing positive for SARS-CoV-2 during the first pandemic wave when testing availability was limited, while relative risks of severe COVID-19 outcomes remained increased in cancer patients throughout 2020. Recent cancer treatment and haematologic malignancy were the strongest risk factors. Funding: Nordic Cancer Union.
ABSTRACT
Approximately 400 million women of reproductive age use hormonal contraceptives worldwide. Eventually, pregnancy sometimes occurs due to irregular use. Use in early pregnancy is found to be associated with child morbidities including cancer, the main reason for disease-related death in children. Here, we add the missing piece about in utero exposure to hormonal contraception and mortality in offspring, including assessments of prognosis in children with cancer. In utero exposure to hormonal contraception may be associated with death since we found a hazard ratio (HR) of 1.22 (95% confidence interval (CI) 1.01-1.48) compared to children of mothers with previous use. The HRs were 1.22 (95% CI 0.99-1.13) for oral combined products and 2.92 (95% CI 1.21-7.04) for non-oral progestin-only products. A poorer prognosis was also found in exposed children with leukemia (3.62 (95% CI: 1.33-9.87)). If causal, hormonal contraception in pregnancy seems detrimental for offspring health and a marker of poorer prognosis in children with leukemia.
ABSTRACT
PURPOSE: To systematically review studies assessing (1) psychometric properties of the maximal oxygen uptake (VO2max) test in PD, (2) VO2max levels in persons with PD (pwPD) compared to healthy controls (HCs), and (3) reported VO2max associations in PD. MATERIALS AND METHODS: Six databases were searched. Descriptive data synthesis was used to summarize psychometric properties and reported VO2max associations. The VO2max means and test end-criteria were calculated using linear mixed models. Simple linear regression was used for associations. RESULTS: The review included 25 studies. Psychometric properties of the VO2max test, reported in one study, showed intraclass correlations of 0.90-0.94 for VO2max. Thirteen studies reported test end-criteria, with only mean respiratory exchange ratio (on medication) and percentage of predicted maximal heart rate (off medication) fulfilling standardized minimum values for the VO2max test. The VO2max was comparable between pwPD and HC as well as between different PD-medication states. Associations between VO2max and age, sex, and fatigue were reported. CONCLUSIONS: In mildly to moderately affected pwPD, limited evidence exists on the psychometric properties of the VO2max test and end-criteria were sparsely reported. Surprisingly, VO2max was comparable between pwPD and HC as well as between different PD-medication states, and only age, sex, and fatigue were associated with VO2max. Implications for rehabilitationIn mildly to moderately affected persons with PD (pwPD), only one study has examined psychometric properties of the VO2max test, reporting excellent test-retest reliability.A general lack of consistency on how to measure and report VO2max end-criteria was observed, but when reported, the end-criteria were most often not met.No difference was found in VO2max between mildly to moderately affected pwPD and HC, or between pwPD across different medication states.The identified negative association between VO2max and fatigue suggests aerobic exercise as a potential symptomatic treatment of fatigue when rehabilitation professionals are treating pwPD.

BACKGROUND AND PURPOSE: No studies have synthesized the literature regarding mechanical muscle function (ie, strength, power, rate of force development [RFD]) in people with Parkinson disease (PD). Here, we aimed to expand our understanding of mechanical muscle function in people with PD (PwPD) by systematically reviewing (1) the psychometric properties of isokinetic/isometric dynamometry in PD, (2) the literature comparing mechanical muscle function in PwPD with healthy controls (HC), and (3) reported associations between muscle mechanical muscle function and functional capacity and/or disease severity. METHODS: Systematic literature search in 6 databases. Included studies had to (1) enroll and report data on PwPD, (2) include assessment(s) of psychometric properties (ie, validity, reliability, responsiveness) of isokinetic/isometric dynamometry in PD, and/or (3) assess mechanical muscle function in both PwPD and HC using isokinetic/isometric dynamometry. RESULTS: A total of 40 studies were included. Aim 1 studies (n = 2) showed high reliability for isometric dynamometry (hip-abductor/dorsiflexor/trunk flexor-extensor/handgrip: intraclass correlations coefficients range = 0.92-0.98). Aim 2 studies (n = 40) showed impaired mechanical muscle function (ie, strength, power, RFD) in PwPD compared with HC (effect sizes range = 0.52-1.89). Aim 3 studies (n = 11) showed weak-to-strong associations between overall and lower extremities muscle strength and functional capacity and/or disease severity outcomes (ie, Unified Parkinson Disease Rating Scale). DISCUSSION AND CONCLUSIONS: Sparse methodological evidence suggests high reliability when using dynamometry in PwPD. Muscle strength, power, and RFD are impaired in PwPD compared with HC. Muscle strength is associated with functional capacity and disease severity.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A403 ).

BACKGROUND: A pregnant woman's health literacy refers to her knowledge, motivation, and skills to access, understand, appraise, and apply health information to make decisions in everyday life concerning her health. Inadequate health literacy increases the risk of adverse pregnancy and birth outcomes. This systematic review aimed to explore existing evidence of women's health literacy levels in the prenatal period. METHODS: We searched four databases: MEDLINE, Embase, CINAHL, and PsycInfo. Study eligibility criteria were: 1) a study population of women in the prenatal period, 2) an English language text, and 3) a clear statement of health literacy assessment. We used the Joanna Briggs Institute (JBI) appraisal checklist for quality assessment of the included studies. We synthesized results using thematic synthesis in three stages 1) coding text, 2) developing descriptive themes, and 3) generating analytical themes. RESULTS: Of the 2,238 studies screened, we included forty-four in the systematic review. Most studies were conducted in the United States of America, some in Iran and Europe, and a few in Australia and Africa. We identified twenty different health-literacy measurement tools used in included studies. Four themes were synthesized: 1) socio-economy and determinants, 2) functional health literacy, 3) interactive health literacy, and 4) critical health literacy. CONCLUSIONS: Low health literacy is associated with socio-economy, including education, employment and ethnicity and age in the prenatal period. Most identified studies (n = 24) addressed functional health literacy including information, understanding, knowledge, oral health knowledge, perception, behavior, and lifestyle. Some studies addressed interactive health literacy (n = 13) including active technology engagement, social network, interaction with health professionals, and group prenatal care. Few studies addressed critical health literacy (n = 4). Evidence of critical health literacy in the prenatal period is sparse, and high-quality research warranted.

In 2015, Uhrbrand et al. published the first review on Parkinson´s disease (PD) and exercise entirely based on randomized controlled trials (RCT) applying strict exercise definitions. The present review aimed to update the PD literature by assessing the effects of different intensive exercise modalities: resistance training (RT), endurance training (ET), and other intensive exercise modalities (OITM). An updated systematic literature search identified 33 new RCTs. Qualitative and quantitative analyses were performed. A total of 18 RT, 14 ET, and 1 OITM studies were identified (adding to the 8 RT, 6 ET, and 4 OITM studies identified by Uhrbrand et al. in 2015). RT, ET, and OITM were feasible, safe, and did not worsen PD symptoms. Furthermore, RT, ET, and OITM may positively affect functional outcomes (e.g., balance) and depressive symptoms in PD but inconsistencies across these findings warrant cautious conclusions. Meta-analyses showed that RT had a positive impact on muscle strength (standardized mean difference (SMD) = 0.83 [95% CI;0.54, 1.12]), functional capacity (Timed Up and Go Test (TUG): SMD = -0.62 [-1.01, -0.24]), and quality of life (SMD = -0.41 [-0.72, -0.09]), while ET had a positive impact on cardiorespiratory fitness (SMD = 0.27 [0.07, 0.47]) and functional capacity (TUG: SMD = -0.21 [-0.46, 0.04], 6-Min Walk Test: SMD = 0.89 [0.17, 1.62]), and a potentially positive impact on "on-medication" UPDRS-III (SMD = -0.15 [-0.38, 0.09]) and "off-medication" UPDRS-III (SMD = -0.19 [-0.41, 0.04]). In conclusion, RT, ET, and OITM all represent safe, feasible, and beneficial adjunct rehabilitation strategies in PD, with particularly RT and ET showing solid effects.
