Cardiac Rehabilitation - methods
2024
Background
Historically, the majority of patients admitted to inpatient exercise-based cardiac rehabilitation (EBCR) have undergone open heart surgery (OHS). However, with advances in minimally invasive cardiac surgery (MICS), these patient groups are also increasingly referred for inpatient EBCR. Herein, we aimed to compare the progress of these groups during rehabilitation.
Methods
In this prospective, nonrandomized study, 403 inpatient EBCR patients were recruited from December 2022 until September 2023 and stratified into two groups: OHS, and MICS. Participants completed a 3-4-week certified EBCR program. The primary endpoint was defined as a change in the 6-minute walk test (6MWT). Moreover, a comprehensive panel of quality-of-life (QoL) assessments were performed at admission and discharge.
Results
At baseline, patients with OHS were older (66 years [IQR 59 – 72]), more often male (83%), and underwent emergency/urgent procedures more often (20%) than patients with MICS. Furthermore, patients with MICS showed a better 6MWT at admission (426 meters [IQR 336 – 483]) compared to patients with OHS (381 meters [IQR 299 – 453]). While all patients were able to increase the distance in the 6MWT, regression analyses in fully adjusted models showed no difference in improvements between the two groups (β -5, 95% CI, -26 – 14,
p
= 0.58). Moreover, during EBCR, we observed significant improvements in all QoL measures in all groups.
Conclusions
In this study, improvements in fitness, as assessed by the 6WMT were observed in all groups. Furthermore, multiple QoL measures improved equally across all groups. These encouraging results emphasize the importance of EBCR.

Thyroglobulin (Tg) could be a sensitive biomarker of iodine nutrition in pregnant women (PW). A dried blood spot (DBS) assay would simplify collection and transport in field studies.
Our aims were to (1) establish and test a reference range for DBS-Tg in PW; (2) determine whether co-measurement of Tg antibodies (Abs) is necessary to define population iodine status.
Standardized cross-sectional studies of 3870 PW from 11 countries. For the DBS-Tg reference range, we included TgAb-negative PW (n = 599) from 3 countries with sufficient iodine intake.
We measured the urinary iodine concentration and DBS thyroid-stimulating hormone, total thyroxin, Tg, and TgAb.
In the reference population, the median DBS-Tg was 9.2 μg/L (95% confidence interval, 8.7 to 9.8 μg/L) and was not significantly different among trimesters. The reference range was 0.3 to 43.5 μg/L. Over a range of iodine intake, the Tg concentrations were U-shaped. Within countries, the median DBS-Tg and the presence of elevated DBS-Tg did not differ significantly between all PW and PW who were TgAb-negative.
A median DBS-Tg of ∼10 μg/L with <3% of values ≥44 μg/L indicated population iodine sufficiency. Concurrent measurement of TgAb did not appear necessary to assess the population iodine status.

Interlaboratory validation of two multiplex quantitative real-time PCR methods to determine species DNA of cow, sheep and goat as a measure of milk proportions in cheese
2013
Milk products like yogurt, flavoured milk-drinks, curd and cheese may be composed of milk different from cow, namely of ruminant species like sheep and goat. Such products experience an increasing demand in Europe and are recognised as healthy and naturally finished specialities. To verify declared milk compositions in these dairy products, two different quantitative multiplex PCR systems have been evaluated in a comparison test with eleven participating laboratories employing two unknown, traditionally manufactured cheeses with different degrees of ripening to determine milk fractions from cow, ewe and goat. Precision and accuracy was investigated by calibration to dilutions of DNA mixtures and to homologous matrix-adapted reference cheeses, respectively. As expected, independent of the particular method, best inter- and intra-laboratory accuracy has been achieved through the use of homologous reference cheese standards. Furthermore, it has been shown that cheese ripening and the concomitant DNA degradation exert an inverse effect on the method’s sensitivity and performance characteristics. Additionally, a broad market survey of different milk products demonstrated its applicability as an efficient analytical tool for food control laboratories to challenge the authenticity of milk and its products from small ruminants.

BACKGROUND: Tobacco use remains the most preventable cause of death and disability in the United States. Public opinion regarding tobacco use is not only an important barometer of the likelihood of effective tobacco-control legislation, but also identifies ongoing public health educational needs. Because > 63,000 children become new smokers annually in Pennsylvania, we chose to evaluate the statewide public health tobacco perspective in order to help tailor future public policy interventions. STUDY DESIGN AND SETTING: Registered voters were randomly contacted in a statewide telephone survey. To reduce response bias, an independent polling firm conducted the 643 structured interviews. RESULTS: Most respondents were >or= 45 years old (55%), female (54%), and had at least some college education (62%). Twenty-eight percent (95% confidence interval [CI], 25 to 32%) were current tobacco users, and 38% (95% CI, 34 to 42%) had lost family members or friends to smoking-related disease. Ninety-two percent (95% CI, 90 to 94%) expressed \"concern\" about adolescent tobacco use, but only 46% (95% CI, 42 to 50%) believed that government needed to do more. Of respondents opposed to government involvement, 65% (95% CI, 61 to 68%) believed it was an improper role for government, or that there are more important non-health government priorities. When framed more personally, 80% (95% CI, 77 to 83%) indicated that elected officials have a responsibility to \"dedicate a significant portion of tobacco settlement\" to prevention. Still, 28% (95% CI, 25 to 32%) would oppose laws restricting smoking in establishments frequented by youth. CONCLUSIONS: Prior public health education initiatives have been effective in shaping the tobacco-related health concerns of Pennsylvania voters. As expected, the overwhelming majority of respondents are concerned about youth tobacco use and agree that money should be spent on tobacco-control initiatives. In contrast, many are reluctant to support \"government\" involvement in what is still seen as a personal issue. Future public health initiatives should focus on this dichotomy and should highlight the utility of an integrated policy approach to tobacco control.

Efficacy and safety of adalimumab every other week versus methotrexate once weekly in children and adolescents with severe chronic plaque psoriasis: a randomised, double-blind, phase 3 trial
2017
Adalimumab is indicated for the treatment of moderate to severe psoriasis in adults. We assessed the efficacy and safety of adalimumab in children and adolescents with severe plaque psoriasis.
This randomised, double-blind, multiperiod, phase 3 trial was done at 38 clinics in 13 countries. Patients (aged ≥4 to <18 years) with severe plaque psoriasis who had not responded to topical therapy were randomly assigned with an interactive voice or web-response system (1:1:1) to receive adalimumab 0·8 mg/kg or 0·4 mg/kg subcutaneously at week 0, then every other week starting at week 1, or oral methotrexate once weekly (0·1–0·4 mg/kg) for 16 weeks. Randomisation was stratified by history of etanercept treatment, with a block size of three. Responders were withdrawn from treatment (for up to 36 weeks) and re-treated with adalimumab (for 16 weeks) if disease became uncontrolled. Ranked primary efficacy endpoints were the proportion of patients who achieved at least 75% improvement from baseline in Psoriasis Area and Severity Index (PASI75) score and clear or minimal physician global assessment (PGA) score at week 16, comparing adalimumab 0·8 mg/kg with methotrexate. Efficacy analysis was by intention to treat, and safety analysis included all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT01251614, and has been completed.
Between Dec 14, 2010, and Feb 5, 2015, 114 patients were randomly assigned to adalimumab 0·8 mg/kg (n=38), adalimumab 0·4 mg/kg (n=39) or methotrexate (n=37). At week 16, PASI75 was achieved in 22 (58%) of 38 patients in the adalimumab 0·8 mg/kg group compared with 12 (32%) of 37 patients in the methotrexate group (p=0·027). 23 (61%) of 38 patients in the adalimumab 0·8 mg/kg group and 15 (41%) of 37 in the methotrexate group achieved clear or minimal PGA (p=0·083). In the adalimumab 0·4 mg/kg group, 17 (44%) of 39 patients achieved PASI75 and 16 (41%) achieved clear or minimal PGA. The most frequent adverse events were infections (17 [45%] of 38 in the adalimumab 0·8 mg/kg group during initial treatment; 22 [56%] of 39 in the adalimumab 0·4 mg/kg group; 21 [57%] of 37 in the methotrexate group). Three serious adverse events were reported, all in patients in the adalimumab 0·4 mg/kg group, and were not judged to be related to study drug.
Treatment with adalimumab 0·8 mg/kg in children and adolescents with severe plaque psoriasis provided significant improvements in PASI75 and a non-significant increase in the proportion of patients who achieved clear or minimal PGA compared with methotrexate. No new safety risks were identified.

BackgroundResearch integrity and research fairness have gained considerable momentum in the past decade and have direct implications for global health epidemiology. Research integrity and research fairness principles should be equally nurtured to produce high-quality impactful research—but bridging the two can lead to practical and ethical dilemmas. In order to provide practical guidance to researchers and epidemiologist, we set out to develop good epidemiological practice guidelines specifically for global health epidemiology, targeted at stakeholders involved in the commissioning, conduct, appraisal and publication of global health research.MethodsWe developed preliminary guidelines based on targeted online searches on existing best practices for epidemiological studies and sought to align these with key elements of global health research and research fairness. We validated these guidelines through a Delphi consultation study, to reach a consensus among a wide representation of stakeholders.ResultsA total of 45 experts provided input on the first round of e-Delphi consultation and 40 in the second. Respondents covered a range of organisations (including for example academia, ministries, NGOs, research funders, technical agencies) involved in epidemiological studies from countries around the world (Europe: 19; Africa: 10; North America: 7; Asia: 5; South-America: 3 Australia: 1). A selection of eight experts were invited for a face-to-face meeting. The final guidelines consist of a set of 6 standards and 42 accompanying criteria including study preparation, protocol development, data collection, data management, data analysis, dissemination and communication.ConclusionWhile guidelines will not by themselves guard global health from questionable and unfair research practices, they are certainly part of a concerted effort to ensure not only mutual accountability between individual researchers, their institutions and their funders but most importantly their joint accountability towards the communities they study and society at large.

Telemedicine in adult intensive care: A systematic review of patient-relevant outcomes and methodological considerations
2025
Given the growing challenges of healthcare, including an aging population and increasing shortages of specialized intensive care staff, this systematic review investigates the efficacy of telemedicine in intensive care compared to standard of care (SoC) or any other type or mode of telemedicine on patient-relevant outcomes for adult intensive care unit (ICU) patients. This systematic review follows Cochrane's methodological standards. Comprehensive searches for any controlled clinical studies were conducted in MEDLINE, Scopus, CINAHL, and CENTRAL (up to 18 April 2024, and an updated search for randomized controlled trials (RCTs) up to 29 September 2025). Twenty-six studies comparing telemedicine in intensive care to SoC with approximately 2,164,508 analysed patients were identified, including data from one cluster RCT (cRCT), two stepped-wedge cluster RCTs (sw-cRCTs), and 23 non-randomized studies of interventions (NRSIs). No other comparisons were identified. Due to high clinical and methodological heterogeneity among studies, no meta-analysis was conducted. For ICU mortality, one cRCT (15,230 patients) and two sw-cRCTs (5,915 patients) showed heterogeneous results: two found no evidence for a difference, while one favoured SoC (very low-certainty). One sw-cRCT (1,462 patients) reporting overall mortality at 180 days suggested no evidence for a difference between groups (very low-certainty). Data from one cRCT (15,230 patients) and one sw-cRCT (1,462 patients) on ICU length of stay (LOS) showed no evidence for a difference between groups (moderate- and very low-certainty). Quality of life from one sw-cRCT (786 patients) indicated no evidence for a difference (very low-certainty). Six NRSIs reported adjusted data on ICU mortality, two on overall mortality, and three on ICU LOS, with heterogeneous results. High risk of bias and substantial heterogeneity limited the certainty, emphasizing the need for robust, patient-centered research in clinical studies to define telemedicine's role in intensive care and optimize its implementation. Future studies should particularly ensure transparent and comprehensive reporting.

Background
Better evidence regarding drug safety in the pediatric population might be generated from existing data sources such as spontaneous reporting systems and electronic healthcare records. The Global Research in Paediatrics (GRiP)–Network of Excellence aims to develop pediatric-specific methods that can be applied to these data sources. A reference set of positive and negative drug–event associations is required.
Objective
The aim of this study was to develop a pediatric-specific reference set of positive and negative drug–event associations.
Methods
Considering user patterns and expert opinion, 16 drugs that are used in individuals aged 0–18 years were selected and evaluated against 16 events, regarded as important safety outcomes. A cross-table of unique drug–event pairs was created. Each pair was classified as potential positive or negative control based on information from the drug’s Summary of Product Characteristics and Micromedex. If both information sources consistently listed the event as an adverse event, the combination was reviewed as potential positive control. If both did not, the combination was evaluated as potential negative control. Further evaluation was based on published literature.
Results
Selected drugs include ibuprofen, flucloxacillin, domperidone, methylphenidate, montelukast, quinine, and cyproterone/ethinylestradiol. Selected events include bullous eruption, aplastic anemia, ventricular arrhythmia, sudden death, acute kidney injury, psychosis, and seizure. Altogether, 256 unique combinations were reviewed, yielding 37 positive (17 with evidence from the pediatric population and 20 with evidence from adults only) and 90 negative control pairs, with the remainder being unclassifiable.
Conclusion
We propose a drug–event reference set that can be used to compare different signal detection methods in the pediatric population.
