Temporal trend of first-line drug choice and treatment continuity for hypertension among citizens 75 years or over - a register-based, cohort study.

BACKGROUND: Limited knowledge of antihypertensive treatment of the elderly potentially impedes effective strategies for hypertension management in this growing patient group. We aimed to investigate temporal trends for first-line drug choice for antihypertensive treatment and treatment continuity among patients ≥75 years from 2000 to 2021. METHODS: Using nationwide Danish registers, patients ≥75 years initiated for the first time on antihypertensive drugs: Angiotensin converting enzyme inhibitors (ACEi), angiotensin II receptor blockers (ARB), beta blockers (BB), calcium channel blockers (CCB), thiazides, or combinations, were identified. Patients with other indications than hypertension were excluded. Treatment continuity was described using claimed prescriptions the first 180 days following study entry. RESULTS: From 2000 to 2021, 170,769 patients (median age 80 years [interquartile range:77-84], 60.3% female) were included. From 2000 to 2003 to 2015-2021 the proportion of first-line drug choice increased for ACEi (8.7% to 14.9%), ARB (4.1% to 23.9%), and CCB (10.7% to 27.6%), decreased for thiazides (60.6% to 15.9%) and remained stable for BB (12.9% to 14.1%) and combinations (2.9% to 3.6%). For 157,457 patients alive after 180 days, discontinuation was highest among patients initiated on thiazides (28.3%) whereas most patients continued the same single drug regimen if they started on ACEi (55.2%), ARB (65.0%), BB (57.2%) or CCB (59.3%). CONCLUSIONS: From 2000 to 2021 thiazides have been replaced by ACEi, ARB and CCB. Thiazides had the lowest treatment continuity while ARB appeared preferred slightly over ACEi. Differences in adherence in relation to first-line drug choice may warrant scrutiny regarding recommendations for the elderly.

Long-Term Cardiovascular Risk Associated With Treatment of Attention-Deficit/Hyperactivity Disorder in Adults.

BACKGROUND: Incrementing numbers of patients treated for attention-deficit/hyperactivity disorder (ADHD) call for scrutiny concerning long-term drug-safety. OBJECTIVES: This study aims to investigate associations between long-term use of ADHD treatment and cardiovascular outcomes. METHODS: Using nationwide registers, adult patients first-time initiated on ADHD treatment between 1998 and 2020 were identified. Exposure groups were prior users, <1 defined daily dose (DDD) per day, ≥1 DDD per day determined at start of follow-up, and 1 year after patients' first claimed prescription. Outcomes were acute coronary syndromes, stroke, heart failure, and a composite of the above. RESULTS: At start of follow-up, 26,357, 31,211, and 15,696 individuals were correspondingly categorized as prior users (42% female, median age: 30 years [Q1-Q3: 23-41 years]), <1 DDD per day (47% female, median age: 31 years [Q1-Q3: 24-41 years]), and ≥1 DDD per day (47% female, median age: 33 years [Q1-Q3: 25-41 years]), respectively. Comparing ≥1 DDD per day with prior users, elevated standardized 10-year absolute risk of stroke (2.1% [95% CI: 1.8%-2.4%] vs 1.7% [95% CI: 1.5%-1.9%]), heart failure (1.2% [95% CI: 0.9%-1.4%] vs 0.7% [95% CI: 0.6%-0.8%]), and the composite outcome (3.9% [95% CI: 3.4%-4.3%] vs 3.0% [95% CI: 2.8 %-3.2%]) was found-with corresponding risk ratios of 1.2 (95% CI: 1.0-1.5), 1.7 (95% CI: 1.3-2.2), and 1.3 (95% CI: 1.1-1.5). No apparent associations were found for acute coronary syndrome (1.0% [95% CI: 0.8%-1.2%] vs 0.9% [95% CI: 0.8%-1.0%]). CONCLUSIONS: Possible associations between elevated long-term cardiovascular risk and increasing dosage of ADHD treatment use in a young patient group should warrant further investigation.

Maternal BCG scars and mortality risk for male and female newborns: observational study from Guinea-Bissau.

BACKGROUND: Maternal priming with Bacille Calmette-Guérin (BCG) has been associated with reduced mortality in male offspring. We investigated this association in a cohort of healthy BCG-vaccinated neonates. METHODS: Observational study within a randomized controlled trial comparing different BCG strains conducted in Guinea-Bissau from 2017-2020. As part of trial inclusion procedures, on the day of discharge from the maternity ward, maternal BCG scar status was evaluated by visual inspection, followed by offspring BCG and polio vaccination. Through mortality data collected at telephone interviews at six weeks and six months of age, we assessed all-cause mortality risk in Cox Proportional Hazards models adjusted for maternal schooling and BCG strain, providing adjusted Mortality Rate Ratios (aMRRs). RESULTS: 64% (11,070/17,275) of mothers had a BCG scar, which for females and overall was not associated with neither admission risk, admission severity nor all-cause mortality. By six months of age, the mortality rate (MR) was 4.1 (200 deaths/4,919 person-years) for the maternal BCG scar cohort and 5.2 (139 deaths/2,661 person-years) for no maternal scar, aMRR=0.86 (0.69-1.06). In males, six-month MRs were 4.3 (109/2,531) for maternal BCG scar vs 6.3 (87/1,376) for no scar, the maternal scar/no scar aMRR being 0.74 (0.56-0.99). In females, six-month MRs were 3.8 (91/2,388) vs 4.0 (52(1,286), the aMRR being 1.04 (0.74-1.47), p for interaction with sex=0.16. CONCLUSION: While we cannot rule out an association in females, being born to a mother with a BCG scar reduced the risk of death during early infancy for BCG-vaccinated males, reproducing findings from previous studies.

Impact of breast-, gastrointestinal-, and lung cancer on prognosis in patients with first-time pulmonary embolism: A Danish nationwide cohort study.

BACKGROUND: Pulmonary embolism (PE) is described as a prognostic factor in patients with cancer however, the prognostic impact of PE remains unknown. This study investigated, the 1-year prognosis following PE in patients with breast-, gastrointestinal-, or lung cancer stratified by cancer status. METHODS: All Danish patients with first-time PE from 2008 to 2018 were included. Cancer status was categorized as no cancer, history of cancer, non-active cancer and active cancer. Unadjusted and age-stratified 1-year risk of death was estimated using the Kaplan-Meier estimator. Cause of death was reported using the Aalen-Johansen method. RESULTS: Of 35,679 patients with PE, 18% had a breast-, gastrointestinal-, or lung cancer. Patients with cancer were older compared with no cancer (69.8 years [IQR: 56.2-79.8]). One-year risk of death (95% confidence interval) for active breast-, gastrointestinal-, and lung cancer was 49.5% (44.0%-54.9%), 75.0% (72.5%-77.4%) and 80.1% (78.0%-82.3%) respectively, compared with 18.9% (18.4%-19.3%) for no cancer. Age-stratified analysis revealed no association with increasing age in non-active lung cancer and all active cancers. Further, non-cardiovascular death accounted for an increasing proportion by cancer status (no cancer < history of cancer < non-active cancer < active cancer). CONCLUSIONS: One-year risk of death was dependent on both cancer type and status; no association with age was found for patients with active cancers. Non-cardiovascular death was leading in non-active and active cancers. Thus, the occurrence of first-time PE could be regarded as a marker of cancer severity for patients with breast-, gastrointestinal-, and lung cancer.

Discovering Subgroups of Children With High Mortality in Urban Guinea-Bissau: Exploratory and Validation Cohort Study.

BACKGROUND: The decline in global child mortality is an important public health achievement, yet child mortality remains disproportionally high in many low-income countries like Guinea-Bissau. The persisting high mortality rates necessitate targeted research to identify vulnerable subgroups of children and formulate effective interventions. OBJECTIVE: This study aimed to discover subgroups of children at an elevated risk of mortality in the urban setting of Bissau, Guinea-Bissau, West Africa. By identifying these groups, we intend to provide a foundation for developing targeted health interventions and inform public health policy. METHODS: We used data from the health and demographic surveillance site, Bandim Health Project, covering 2003 to 2019. We identified baseline variables recorded before children reached the age of 6 weeks. The focus was on determining factors consistently linked with increased mortality up to the age of 3 years. Our multifaceted methodological approach incorporated spatial analysis for visualizing geographical variations in mortality risk, causally adjusted regression analysis to single out specific risk factors, and machine learning techniques for identifying clusters of multifactorial risk factors. To ensure robustness and validity, we divided the data set temporally, assessing the persistence of identified subgroups over different periods. The reassessment of mortality risk used the targeted maximum likelihood estimation (TMLE) method to achieve more robust causal modeling. RESULTS: We analyzed data from 21,005 children. The mortality risk (6 weeks to 3 years of age) was 5.2% (95% CI 4.8%-5.6%) for children born between 2003 and 2011, and 2.9% (95% CI 2.5%-3.3%) for children born between 2012 and 2016. Our findings revealed 3 distinct high-risk subgroups with notably higher mortality rates, children residing in a specific urban area (adjusted mortality risk difference of 3.4%, 95% CI 0.3%-6.5%), children born to mothers with no prenatal consultations (adjusted mortality risk difference of 5.8%, 95% CI 2.6%-8.9%), and children from polygamous families born during the dry season (adjusted mortality risk difference of 1.7%, 95% CI 0.4%-2.9%). These subgroups, though small, showed a consistent pattern of higher mortality risk over time. Common social and economic factors were linked to a larger share of the total child deaths. CONCLUSIONS: The study's results underscore the need for targeted interventions to address the specific risks faced by these identified high-risk subgroups. These interventions should be designed to work to complement broader public health strategies, creating a comprehensive approach to reducing child mortality. We suggest future research that focuses on developing, testing, and comparing targeted intervention strategies unraveling the proposed hypotheses found in this study. The ultimate aim is to optimize health outcomes for all children in high-mortality settings, leveraging a strategic mix of targeted and general health interventions to address the varied needs of different child subgroups.

Aortic Calcification is Associated With the Difference Between Invasive Central and Cuff-Measured Brachial Blood Pressure in Chronic Kidney Disease.

BACKGROUND: Chronic kidney disease (CKD) is associated with accelerated vascular calcification and increased central systolic blood pressure when measured invasively (invCSBP) relative to cuff-based brachial systolic blood pressure (cuffSBP). The contribution of aortic wall calcification to this phenomenon has not been clarified. We, therefore, examined the effects of aortic calcification on cuffSBP and invCSBP in a cohort of patients representing all stages of CKD. METHODS: During elective coronary angiography, invCSBP was measured in the ascending aorta with a fluid-filled catheter with simultaneous recording of cuffSBP using an oscillometric device. Furthermore, participants underwent a non-contrast computed tomography scan of the entire aorta with observer-blinded calcification scoring of the aortic wall ad modum Agatston. RESULTS: We included 168 patients (mean age 67.0 ±â€…10.5, 38 females) of whom 38 had normal kidney function, while 30, 40, 28, and 32 had CKD stages 3a, 3b, 4, and 5, respectively. Agatston scores adjusted for body surface area ranged from 48 to 40,165. We found that invCSBP increased 3.6 (95% confidence interval 1.4-5.7) mm Hg relative to cuffSBP for every 10,000-increment in aortic Agatston score. This association remained significant after adjustment for age, diabetes, antihypertensive treatment, smoking, eGFR, and BP level. No such association was found for diastolic BP. CONCLUSIONS: Patients with advanced aortic calcification have relatively higher invCSBP for the same cuffSBP as compared to patients with less calcification. Advanced aortic calcification in CKD may therefore result in hidden central hypertension despite apparently well-controlled cuffSBP. ClinicalTrials.gov identifier: NCT04114695.

Effects of Neonatal BCG-Japan Versus BCG-Russia Vaccination on Overall Mortality and Morbidity: Randomized Controlled Trial From Guinea-Bissau (BCGSTRAIN II).

Background: Vaccination with the Danish strain of bacille Calmette-Guérin (BCG) has been associated with pronounced reductions in all-cause neonatal mortality and morbidity. Developing a skin reaction postvaccination is associated with markedly reduced mortality risk. It is unknown whether the beneficial nonspecific effects are maintained across different BCG strains. Methods: This was an open-label randomized controlled trial in Guinea-Bissau, comparing BCG-Japan (n = 8754) versus BCG-Russia (n = 8752) for all-cause hospital admission risk by 6 weeks of age (primary outcome) and 6 months of age. Additional secondary outcomes were in-hospital case-fatality risk (CFR), all-cause mortality, and BCG skin reaction prevalence. Participants were followed through telephone calls at 6 weeks and 6 months, with a subgroup also visited at home. We assessed admission and mortality risk in Cox models providing incidence rate ratios (IRRs) and mortality rate ratios. CFR and skin reactions were assessed by binomial regression providing risk ratios. Analyses were done overall and stratified by sex. Results: BCG strain was not associated with admission risk, the BCG-Japan/BCG-Russia IRR being 0.92 (95% confidence interval [CI], .81-1.05) by 6 weeks and 0.92 (95% CI, .82-1.02) by 6 months. By 6 months of age, there were significantly fewer BCG-Japan infants with no skin reaction (1%) than for BCG-Russia (2%), the risk ratio being 0.36 (95% CI, .16-.81). BCG-Japan skin reactions were also larger. Conclusions: Both vaccines induced a skin reaction in almost all participants. The BCG strains had comparable effects on morbidity and mortality, but BCG-Japan was associated with more and larger skin reactions that are indicators of lower mortality risk.

Effect of distributing locally produced cloth facemasks on COVID-19-like illness and all-cause mortality-a cluster-randomised controlled trial in urban Guinea-Bissau.

Facemasks have been employed to mitigate the spread of SARS-CoV-2. The community effect of providing cloth facemasks on COVID-19 morbidity and mortality is unknown. In a cluster randomised trial in urban Bissau, Guinea-Bissau, clusters (geographical areas with an average of 19 houses), were randomised to an intervention or control arm using computer-generated random numbers. Between 20 July 2020 and 22 January 2021, trial participants (aged 10+ years) living in intervention clusters (n = 90) received two 2-layer cloth facemasks, while facemasks were only distributed later in control clusters (n = 91). All participants received information on COVID-19 prevention. Trial participants were followed through a telephone interview for COVID-19-like illness (3+ symptoms), care seeking, and mortality for 4 months. End-of-study home visits ensured full mortality information and distribution of facemasks to the control group. Individual level information on outcomes by trial arm was compared in logistic regression models with generalised estimating equation-based correction for cluster. Facemasks use was mandated. Facemask use in public areas was assessed by direct observation. We enrolled 39,574 trial participants among whom 95% reported exposure to groups of >20 persons and 99% reported facemasks use, with no difference between trial arms. Observed use was substantially lower (~40%) with a 3%, 95%CI: 0-6% absolute difference between control and intervention clusters. Half of those wearing a facemask wore it correctly. Few participants (532, 1.6%) reported COVID-19-like illness; proportions did not differ by trial arm: Odds Ratio (OR) = 0.81, 95%CI: 0.57-1.15. 177 (0.6%) participants reported consultations and COVID-19-like illness (OR = 0.83, 95%CI: 0.56-1.24); 89 participants (0.2%) died (OR = 1.34, 95%CI: 0.89-2.02). Hence, though trial participants were exposed to many people, facemasks were mostly not worn or not worn correctly. Providing facemasks and messages about correct use did not substantially increase their use and had limited impact on morbidity and mortality. Trial registration: clinicaltrials.gov: NCT04471766.

The association between BCG scars and self-reported chronic diseases: A cross-sectional observational study within an RCT of Danish health care workers.

INTRODUCTION: The live-attenuated vaccines Bacillus Calmette-Guérin (BCG) and Vaccinia have been associated with beneficial non-specific effects. We assessed the prevalence of BCG and Vaccinia vaccine scars in a cohort of Danish health care workers and investigated the association between the presence of vaccine scars and self-reported chronic diseases. METHODS: Cross-sectional study utilizing baseline data collected during 2020-2021 at enrollment in a BCG trial aiming to assess the effect of BCG vaccination on absenteeism and infectious disease morbidity during the SARS-COV-2 pandemic. In Denmark, Vaccinia was discontinued in 1977, and BCG was phased out in the early 1980s. We used logistic regression analysis (adjusted for sex, birth year, and smoking status) to estimate the association between scar status and chronic diseases, providing adjusted Odds Ratios (aORs) with 95 % Confidence Intervals, for participants born before 1977, and born from 1965 to 1976. RESULTS: The cohort consisted of 1218 participants (206 males; 1012 females) with a median age of 47 years (Q1-Q3: 36-56). Among participants born 1965-1976 (n = 403), who experienced the phase-outs, having BCG and/or Vaccinia scar(s) vs. having no vaccine scars yielded an aOR of 0.51 (0.29-0.90) of self-reported chronic disease; an effect primarily driven by BCG. In the same birth cohort, having vaccine scar(s) was most strongly associated with a lower prevalence of chronic respiratory and allergic diseases; the aORs being 0.39 (0.16-0.97) and 0.39 (0.16-0.91), respectively. CONCLUSION: Having a BCG scar was associated with a lower prevalence of self-reported chronic disease.

Cannabis for chronic pain: cardiovascular safety in a nationwide Danish study.

BACKGROUND AND AIMS: A rising number of countries allow physicians to treat chronic pain with medical cannabis. However, recreational cannabis use has been linked with cardiovascular side effects, necessitating investigations concerning the safety of prescribed medical cannabis. METHODS: Using nationwide Danish registers, patients with chronic pain initiating first-time treatment with medical cannabis during 2018-21 were identified and matched 1:5 to corresponding control patients on age, sex, chronic pain diagnosis, and concomitant use of other pain medication. The absolute risks of first-time arrhythmia (atrial fibrillation/flutter, conduction disorders, paroxysmal tachycardias, and ventricular arrhythmias) and acute coronary syndrome were reported comparing medical cannabis use with no use. RESULTS: Among 1.88 million patients with chronic pain (46% musculoskeletal, 11% cancer, 13% neurological, and 30% unspecified pain), 5391 patients claimed a prescription of medical cannabis [63.2% women, median age: 59 (inter-quartile range 48-70) years] and were compared with 26 941 control patients of equal sex- and age composition. Arrhythmia was observed in 42 and 107 individuals, respectively, within 180 days. Medical cannabis use was associated with an elevated risk of new-onset arrhythmia {180-day absolute risk: 0.8% [95% confidence interval (CI) 0.6%-1.1%]} compared with no use [180-day absolute risk: 0.4% (95% CI 0.3%-0.5%)]: a risk ratio of 2.07 (95% CI 1.34-2.80) and a 1-year risk ratio of 1.36 (95% CI 1.00-1.73). No significant association was found for acute coronary syndrome [180-day risk ratio: 1.20 (95% CI 0.35-2.04)]. CONCLUSIONS: In patients with chronic pain, the use of prescribed medical cannabis was associated with an elevated risk of new-onset arrhythmia compared with no use-most pronounced in the 180 days following the initiation of treatment.

Using BCG Vaccine to Enhance Nonspecific Protection of Health Care Workers During the COVID-19 Pandemic: A Randomized Controlled Trial.

BACKGROUND: The BCG (Bacillus Calmette-Guérin) vaccine can induce nonspecific protection against unrelated infections. We aimed to test the effect of BCG on absenteeism and health of Danish health care workers (HCWs) during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A single-blinded randomized controlled trial included 1221 HCWs from 9 Danish hospitals. Participants were randomized 1:1 to standard dose BCG or placebo. Primary outcome was days of unplanned absenteeism. Main secondary outcomes were incidence of COVID-19, all-cause hospitalization, and infectious disease episodes. RESULTS: There was no significant effect of BCG on unplanned absenteeism. Mean number of days absent per 1000 workdays was 20 in the BCG group and 17 in the placebo group (risk ratio, 1.23; 95% credibility interval, 0.98-1.53). BCG had no effect on incidence of COVID-19 or all-cause hospitalization overall. In secondary analyses BCG revaccination was associated with higher COVID-19 incidence (hazard ratio [HR], 2.47; 95% confidence interval [CI], 1.07-5.71), but also reduced risk of hospitalization (HR, 0.28; 95% CI, .09-.86). The incidence of infectious disease episodes was similar between randomization groups (HR, 1.09; 95% CI, .96-1.24). CONCLUSIONS: In this relatively healthy cohort of HCWs, there was no overall effect of BCG on any of the study outcomes.

Effect of national immunisation campaigns with oral polio vaccine on all-cause mortality in children in rural northern Ghana: 20 years of demographic surveillance cohort data.

Background: Studies from Guinea-Bissau and Bangladesh have shown that campaigns with oral polio vaccine (C-OPV) may be associated with 25-31% lower child mortality. Between 1996 and 2015, Ghana had 50 national C-OPVs and numerous campaigns with vitamin A supplementation (VAS), and measles vaccine (MV). We investigated whether C-OPVs had beneficial non-specific effects (NSEs) on child survival in northern Ghana. Methods: We used data from a health and demographic surveillance system in the Navrongo Health Research Centre in rural northern Ghana to examine mortality from day 1-5 years of age. We used Cox models with age as underlying time scale to calculate hazard ratios (HR) for the time-varying covariate "after-campaign" mortality versus "before-campaign" mortality, adjusted for temporal change in mortality, other campaign interventions and stratified for season at risk. Findings: From 1996 to 2015, 75,610 children were followed for 280,156 person-years between day 1 and 5 years of age. In initial analysis, assuming a common effect across all ages, we did not find that OPV-only campaigns significantly reduced all-cause mortality, the HR being 0.96 (95% CI: 0.88-1.05). However, we subsequently found the HR differed strongly by age group, being 0.92 (0.75-1.13), 1.29 (1.10-1.51), 0.79 (0.66-0.94), 0.67 (0.53-0.86) and 1.03 (0.78-1.36) respectively for children aged 0-2, 3-5, 6-8, 9-11 and above 12 months of age (p < 0.001). Triangulation of the evidence from this and previous studies suggested that increased frequency of C-OPVs and a different historical period could explain these results. Interpretation: In Ghana, C-OPVs had limited effects on overall child survival. However, triangulating the evidence suggested that NSEs of C-OPVs depend on age of first exposure and routine vaccination programs. C-OPVs had beneficial effects for children that were not exposed before 6 months of age. These non-specific effects of OPV should be exploited to further reduce child mortality.

Fibroblast-derived matrix models desmoplastic properties and forms a prognostic signature in cancer progression.

The desmoplastic reaction observed in many cancers is a hallmark of disease progression and prognosis, particularly in breast and pancreatic cancer. Stromal-derived extracellular matrix (ECM) is significantly altered in desmoplasia, and as such plays a critical role in driving cancer progression. Using fibroblast-derived matrices (FDMs), we show that cancer cells have increased growth on cancer associated FDMs, when compared to FDMs derived from non-malignant tissue (normal) fibroblasts. We assess the changes in ECM characteristics from normal to cancer-associated stroma at the primary tumor site. Compositional, structural, and mechanical analyses reveal significant differences, with an increase in abundance of core ECM proteins, coupled with an increase in stiffness and density in cancer-associated FDMs. From compositional changes of FDM, we derived a 36-ECM protein signature, which we show matches in large part with the changes in pancreatic ductal adenocarcinoma (PDAC) tumor and metastases progression. Additionally, this signature also matches at the transcriptomic level in multiple cancer types in patients, prognostic of their survival. Together, our results show relevance of FDMs for cancer modelling and identification of desmoplastic ECM components for further mechanistic studies.

Obstructive sleep apnea, coronary calcification and arterial stiffness in patients with diabetic kidney disease.

BACKGROUND AND AIMS: Obstructive sleep apnea (OSA) may accelerate arterial calcification, but the relation remains unexplored in diabetic kidney disease (DKD). We examined the associations between OSA, coronary calcification and large artery stiffness in patients with DKD and reduced renal function. METHODS: Patients with type 2 diabetes, estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2 and urine albumin-creatinine ratio (UACR) > 30 mg/g were tested for OSA quantified by the apnea-hypopnea index (AHI, events/hour). Patients without OSA (AHI< 5) were compared to patients with moderate (AHI 15-29) or severe (AHI ≥30) OSA and underwent computed tomography angiography with coronary Agatston scoring (CAS) to quantify coronary calcification. Arterial stiffness was determined as carotid-femoral pulse wave velocity (PWV). RESULTS: Among 114 patients with acceptable AHI recordings had 43 no OSA, 33 mild OSA and 38 moderate-severe OSA. Mean age of the 74 patients completing the study was 71.5 ± 9.4 years (73% males), eGFR 32.2 ± 12.3 ml/min/1.73 m2 and UACR 533 (192-1707) mg/g. CAS (ln-transformed) was significantly higher in patients with OSA compared to patients without (6.6 ± 1.7 vs. 5.6 ± 2.4, p = 0.04), and the same was observed for PWV (11.9 ± 2.7 vs. 10.5 ± 2.2 m/s, p = 0.02). In multivariable linear regression analyses adjusted for sex, age, body mass index, UACR, and mean arterial pressure, moderate-severe OSA remained significantly associated with PWV but not with CAS. Dominance analysis revealed OSA as the third and second most important factor relative to CAS and PWV respectively. CONCLUSIONS: In DKD patients, moderate-severe OSA is a significant predictor of arterial stiffness but is not independently associated with coronary calcification.

Patient mortality following new-onset heart failure stratified by cancer type and status.

AIM: Expected 1-year survival is essential to risk stratification of patients with heart failure (HF); however, little is known about the 1-year prognosis of patients with HF and cancer. Thus, the objective was to investigate the 1-year prognosis following new-onset HF stratified by cancer status in patients with breast, gastrointestinal, or lung cancer. METHODS AND RESULTS: All Danish patients with new-onset HF from 2000 to 2018 were included. Cancer status was categorized as history of cancer (no cancer-related contact within 5 years of HF diagnosis), non-active cancer (curative intended procedure administered) and active cancer. Standardized 1-year all-cause mortality was reported using G-computation. Age-stratified 1-year all-cause mortality was estimated using the Kaplan-Meier estimator. In total, 193 359 patients with HF were included, 7.3% had either a breast, gastrointestinal, or lung cancer diagnosis. Patients with cancer were older and more comorbid than patients without cancer. Standardized 1-year all-cause mortality (95% confidence intervals) was 24.6% (23.0-26.2%), 27.1% (25.5-28.6%), and 29.9% (25.9-34.0%) for history of breast, gastrointestinal and lung cancer, respectively, which was comparable to patients with non-active cancers. For active breast, gastrointestinal and lung cancer, standardized 1-year all-cause mortality was 36.2% (33.8-38.6%), 49.0% (47.2-50.9%), and 61.6% (59.7-63.5%), respectively. One-year all-cause mortality increased incrementally with age, except for active lung cancer. CONCLUSION: Standardized 1-year all-cause mortality was comparable for patients with history of cancer and non-active cancer regardless of cancer type, but varied comprehensively for active cancers. Prognostic impact of age was limited for active lung cancer. Thus, granular stratification of cancer is necessary for optimized management of new-onset HF.

Using real-life data to model the impact of increasing BCG vaccination coverage and scar prevalence on all-cause infant mortality.

PURPOSE: Estimating the potential impact on infant mortality of increasing Bacille Calmette-Guérin (BCG) vaccination coverage and BCG scar prevalence. METHODS: Guinea-Bissau Health and Demographic Surveillance System data on BCG vaccination coverage, scar status, and all-cause mortality were used for this study. Mortality risk (MR) by scar status was assessed in Cox models providing adjusted mortality rate ratios (aMRRs). Distributions were fitted for survival, vaccination coverage, and scar prevalence. Models for 12-month mortality were calculated. We utilized World Bank data on birth rates and mortality rates to assess the potential global impact of optimizing BCG vaccination programs. RESULTS: BCG coverage was 81% and scar prevalence 42% among 2-month-old infants, and the 1- to 12-month scar/no scar aMRR was 0.40 (0.22, 0.76). Modeling 2-month 99% vaccination coverage with 95% developing scars would change the 1- to 12-month MR by -8% (-21%, +12%). Globally, the reduction in the MR between 1- and 12-month would be -14% (-14%, -15%), corresponding to -208,075 (-214,453, -204,023) fewer infant deaths/year. CONCLUSIONS: We confirmed previous observations: having a BCG scar markedly reduces infant MR. Increasing current global 2-month BCG vaccination coverage from 76% to 99%, and scar prevalence among vaccinated infants from 52% to 95% might reduce global infant mortality by >200,000 deaths/year. Thus, optimizing BCG vaccination programs to focus on increasing early BCG vaccination coverage and the overall scar prevalence would have major public health benefits.

Prevention of Taste Alterations in Patients with Cancer Receiving Paclitaxel- or Oxaliplatin-Based Chemotherapy-A Pilot Trial of Cannabidiol.

INTRODUCTION: Taste alteration is a common adverse effect of chemotherapy. This study aimed to investigate the effect of cannabidiol (CBD) on Lean Body Mass (LBM), and taste alterations during oxaliplatin- or paclitaxel-based chemotherapy. METHODS: LBM was estimated by bioelectrical impedance analysis (BIA), and taste perception was evaluated by a randomized sensory test of six samples: sweet, salt, and umami, all in weak and strong concentrations. Taste perceptions were scored on visual analog scales. Patients in the intervention group received oral CBD 300 mg/day for 8 days; patients in the control group did not. Patients were followed for three cycles of chemotherapy. RESULTS: Twenty-two/ten patients (intervention/control group) were eligible. No effects on LBM were demonstrated. At baseline, the control group was able to differentiate between weak and strong saltiness and weak and strong sweetness but lost this ability after three cycles of chemotherapy. At baseline, the intervention group was unable to differentiate between the concentrations but gained the ability to significantly differentiate between weak and strong sweetness (p = 0.03) and weak and strong saltiness (p = 0.04) after three cycles of chemotherapy and treatment with CBD. CONCLUSIONS: CBD may improve patients' ability to differentiate taste strengths during chemotherapy.

The Validity of a New Procedure-Based Definition of Cancer Status in Patients with Breast-, Lung- and Colorectal Cancer in the Danish National Patient Registry.

Background/Aim: The Danish National Patient Registry (DNPR) provides unique epidemiological insight, but often lacks granular data. We propose a procedure-based definition of cancer status in patients with breast-, lung- and colorectal cancer, which can be applied to administrative health databases. New definitions of cancer status are needed as mortality and morbidity are closely linked to cancer status, yet most studies only use duration since cancer diagnosis as a severity marker. The aim of the study was to validate a new pragmatic definition. Methods: Medical journals of 600 patients, with breast-, lung- and colorectal cancer from the Department of Oncology at Herlev-Gentofte Hospital were retrospectively reviewed. We defined active cancer as a cancer diagnosis, not followed by a potentially curative procedure within 6 months of the diagnosis. The remaining patients were characterized as having non-active cancer. This dichotomization was then compared to a cancer status assessment based on treatment received and paraclinical test such as their first post-procedural control scan. Based on this comparison, we calculated the positive predictive value (PPV) of our definitions of active and non-active cancer. Results: The calculated PPVs for active breast-, lung- and colorectal cancer were 87% (CI 95%: 0.74-0.99), 91% (CI 95%: 0.87-0.96) and 82% (CI 95%: 0.73-0.91). The PPVs for non-active breast-, lung- and colorectal cancer were 95% (CI 95%: 0.92-0.99), 91% (CI 95%: 0.82-0.99) and 73% (CI 95%: 0.66-0.81), respectively. Conclusion: We found an overall high PPV for both active and non-active cancer across all three types of cancer.

Randomized clinical trials of COVID-19 vaccines: Do adenovirus-vector vaccines have beneficial non-specific effects?

We examined the possible non-specific effects of novel mRNA- and adenovirus-vector COVID-19 vaccines by reviewing the randomized control trials (RCTs) of mRNA and adenovirus-vector COVID-19 vaccines. We calculated mortality risk ratios (RRs) for mRNA COVID-19 vaccines vs. placebo recipients and compared them with the RR for adenovirus-vector COVID-19 vaccine recipients vs. controls. The RR for overall mortality of mRNA vaccines vs. placebo was 1.03 (95% confidence interval [CI]: 0.63-1.71). In the adenovirus-vector vaccine RCTs, the RR for overall mortality was 0.37 (0.19-0.70). The two vaccine types differed significantly with respect to impact on overall mortality (p = 0.015). The RCTs of COVID-19 vaccines were unblinded rapidly, and controls were vaccinated. The results may therefore not be representative of the long-term effects. However, the data argue for performing RCTs of mRNA and adenovirus-vector vaccines head-to-head comparing long-term effects on overall mortality.

Heart Failure Following Anti-Inflammatory Medications in Patients With Type 2 Diabetes Mellitus.

BACKGROUND: Fluid retention and endothelial dysfunction have been related to use of nonsteroidal anti-inflammatory drugs (NSAIDs), and type 2 diabetes mellitus (T2DM) has been linked to both a decline in kidney function and subclinical cardiomyopathy. OBJECTIVES: The authors hypothesized that short-term use of NSAIDs could lead to subsequent development of incident heart failure (HF) in patients with T2DM. METHODS: Using nationwide Danish registers, we identified patients diagnosed with T2DM during 1998 to 2021 and included patients without previous HF, rheumatic disease, or use of NSAIDs 120 days before diagnosis. Associations between NSAIDs and first-time HF hospitalization were investigated using a case-crossover design with 28-day exposure windows, and ORs with 95% CIs were reported. RESULTS: Included were 331,189 patients with T2DM: 44.2% female, median age of 62 years (IQR: 52-71 years); 23,308 patients were hospitalized with HF during follow-up, and 16% of patients claimed at least 1 NSAID prescription within 1 year. Short-term use of NSAIDs was associated with increased risk of HF hospitalization (OR: 1.43; 95% CI: 1.27-1.63), most notably in subgroups with age ≥80 years (OR: 1.78; 95% CI: 1.39-2.28), elevated hemoglobin (Hb) A1c levels treated with 0 to 1 antidiabetic drug (OR: 1.68; 95% CI: 1.00-2.88), and without previous use of NSAIDs (OR: 2.71; 95% CI: 1.78-4.23). CONCLUSIONS: NSAIDs were widely used and were associated with an increased risk of first-time HF hospitalization in patients with T2DM. Patients with advanced age, elevated HbA1c levels, and new users of NSAID seemed more susceptible. These findings could guide physicians prescribing NSAIDs.
