The Palamas Archaeological Project 2023. A preliminary report of the Greek–Swedish collaboration in the municipality of Palamas, region of Karditsa, Thessaly

The 2023 fieldwork in the area of Palamas, Thessaly, was severely hampered by catastrophic weather events affecting the area. In spite of this, the project managed to conduct excavations, surface and architectural surveys, as well as geophysical prospection at a number of sites in the region. The work continues to highlight the chronological breadth of archaeological remains in the area, as well as further details regarding little-known periods of Thessalian history.

The Palamas Archaeological Project. A preliminary report of the 2022 fieldwork conducted by the ongoing Greek–Swedish archaeological field programme in Palamas, region of Karditsa, Thessaly

This paper presents the preliminary results from the 2022 fieldwork of the Palamas Archaeological Project, an ongoing Greek–Swedish collaboration in the region of Karditsa, Thessaly. Working over the course of two separate field seasons, the project team conducted aerial, architectural, fieldwalking, and geophysical surveys at a number of sites within the survey area, including at the important multi-phase fortified settlements at Metamorfosi and Vlochos. Limited excavations were also conducted at the latter site, producing new evidence for the Hellenistic and Early Byzantine phases of the ancient city, including a probable cemetery. The work continues to add to the knowledge of the archaeology of the region, highlighting the long and dynamic history of human habitation in western Thessaly.

Health effects of reduced occupational sedentary behaviour in type 2 diabetes using a mobile health intervention: a study protocol for a 12-month randomized controlled trial—the ROSEBUD study

BackgroundShort-term trials conducted in adults with type 2 diabetes mellitus (T2DM) showed that reducing sedentary behaviour by performing regular short bouts of light-intensity physical activity enhances health. Moreover, support for reducing sedentary behaviour may be provided at a low cost via mobile health technology (mHealth). There are a wide range of mHealth solutions available including SMS text message reminders and activity trackers that monitor the physical activity level and notify the user of prolonged sitting periods. The aim of this study is to evaluate the effects of a mHealth intervention on sedentary behaviour and physical activity and the associated changes in health in adults with T2DM.MethodsA dual-arm, 12-month, randomized controlled trial (RCT) will be conducted within a nationwide Swedish collaboration for diabetes research in primary health care. Individuals with T2DM (n = 142) and mainly sedentary work will be recruited across primary health care centres in five regions in Sweden. Participants will be randomized (1:1) into two groups. A mHealth intervention group who will receive an activity tracker wristband (Garmin Vivofit4), regular SMS text message reminders, and counselling with a diabetes specialist nurse, or a comparator group who will receive counselling with a diabetes specialist nurse only. The primary outcomes are device-measured total sitting time and total number of steps (activPAL3). The secondary outcomes are fatigue, health-related quality of life and musculoskeletal problems (self-reported questionnaires), number of sick leave days (diaries), diabetes medications (clinical record review) and cardiometabolic biomarkers including waist circumference, mean blood pressure, HbA1c, HDL-cholesterol and triglycerides.DiscussionSuccessful interventions to increase physical activity among those with T2DM have been costly and long-term effectiveness remains uncertain. The use of mHealth technologies such as activity trackers and SMS text reminders may increase awareness of prolonged sedentary behaviour and encourage increase in regular physical activity. mHealth may, therefore, provide a valuable and novel tool to improve health outcomes and clinical management in those with T2DM. This 12-month RCT will evaluate longer-term effects of a mHealth intervention suitable for real-world primary health care settings.Trial registrationClinicalTrials.gov NCT04219800.

The power and limits of expertise: Swiss–Swedish linking of vehicle emission standards in the 1970s and 1980s

AbstractRecent decades have witnessed increased public concern about vehicle emissions and growing frustration with political inaction and business preferences for the status quo. This article provides historical perspective on such regulatory dynamics by analyzing the Swiss and the Swedish cases of vehicle emission governance in the1970s-1980s. Relying on archival documents detailing the policy process in both countries as well as on international regulatory arenas, the analysis focuses on political solutions for reducing the toxicity of vehicle emissions. It uncovers the influence of national as well as international business groups and the existence of the tension between various national ministries, arising from conflicting environmental and trade-related goals. Is also highlights the importance of different institutional settings in creating the expertise to explain the political outcomes. While the Swiss corporatist system gave a great deal of power to a variety of interest groups at each stage of the political process, the Swedish government invested significant resources in the creation of independent expertise and enjoyed a relative autonomy, despite the importance of the Swedish car industry. The analysis also assesses the importance of the Swiss–Swedish collaboration in overcoming certain obstacles and their contribution to the implementation of stricter regulations in Europe that ultimately occurred at the margins of the European Economic Community.

No association between moist oral snuff (snus) use and oral cancer: pooled analysis of nine prospective observational studies.

Aims: Worldwide, smokeless-tobacco use is a major risk factor for oral cancer. Evidence regarding the particular association between Swedish snus use and oral cancer is, however, less clear. We used pooled individual data from the Swedish Collaboration on Health Effects of Snus Use to assess the association between snus use and oral cancer. Methods: A total of 418,369 male participants from nine cohort studies were followed up for oral cancer incidence through linkage to health registers. We used shared frailty models with random effects at the study level, to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for confounding factors. Results: During 9,201,647 person-years of observation, 628 men developed oral cancer. Compared to never-snus use, ever-snus use was not associated with oral cancer (adjusted HR 0.90, 95% CI: 0.74, 1.09). There were no clear trends in risk with duration or intensity of snus use, although lower intensity use (⩽ 4 cans/week) was associated with a reduced risk (HR 0.65, 95% CI: 0.45, 0.94). Snus use was not associated with oral cancer among never smokers (HR 0.87, 95% CI: 0.57, 1.32). Conclusions: Swedish snus use does not appear to be implicated in the development of oral cancer in men.

Smokeless tobacco (snus) use and colorectal cancer incidence and survival: Results from nine pooled cohorts.

Although smoking is considered to be an established risk factor for colorectal cancer, the current evidence on the association between smokeless tobacco and colorectal cancer is scant and inconclusive. We used pooled individual data from the Swedish Collaboration on Health Effects of Snus Use to assess this association. A total of 417,872 male participants from nine cohort studies across Sweden were followed up for incidence of colorectal cancer and death. Outcomes were ascertained through linkage to health registers. We used shared frailty models with random effects at the study level to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During 7,135,504 person-years of observation, 4170 men developed colorectal cancer. There was no clear association between snus use and colorectal cancer overall. Exclusive current snus users, however, had an increased risk of rectal cancer (HR 1.40: 95% CI 1.09, 1.79). There were no statistically significant associations between snus use and either all-cause or colorectal cancer-specific mortality after colorectal cancer diagnosis. Our findings, from a large sample, do not support any strong relationships between snus use and colorectal cancer risk and survival among men. However, the observed increased risk of rectal cancer is noteworthy, and in merit of further attention.

Use of moist oral snuff (snus) and pancreatic cancer: Pooled analysis of nine prospective observational studies.

While smoking is a well-established risk factor for pancreatic cancer, the effect of smokeless tobacco is less well understood. We used pooled individual data from the Swedish Collaboration on Health Effects of Snus Use to assess the association between Swedish snus use and the risk of pancreatic cancer. A total of 424,152 male participants from nine cohort studies were followed up for risk of pancreatic cancer through linkage to health registers. We used shared frailty models with random effects at the study level, to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for confounding factors. During 9,276,054 person-years of observation, 1,447 men developed pancreatic cancer. Compared to never-snus use, current snus use was not associated with risk of pancreatic cancer (HR 0.96, 95% CI 0.83-1.11) after adjustment for smoking. Swedish snus use does not appear to be implicated in the development of pancreatic cancer in men. Tobacco smoke constituents other than nicotine or its metabolites may account for the relationship between smoking and pancreatic cancer.

Exchange of knowledge and expertise for sustainable urban development: experiences from cross-disciplinary and transnational cooperation between practitioners and researchers in the Öresund region

This article presents the work of a cross-disciplinary Danish–Swedish collaboration project. The aim was to create best practices for sustainable urban settlements in the Öresund Region. Researchers and practitioners from municipalities in the region evaluated local and European projects for new urban areas and urban renewal using six concepts – identity, density, diversity, landscape, resources and governance. These concepts were also used for creating scenarios for four case areas and for a general discussion of sustainable urban environments summarised in a toolbox. The cooperation revealed diverse approaches to urban renewal and the significance of local legislation and financial prerequisites for renewal processes.

Enhancing adherence to antiretroviral therapy at the HIV clinic in resource constrained countries; the Tanzanian experience

To evaluate various strategies aimed at improving adherence to antiretroviral therapy (ART). Patients initiated on ART at Muhimbili National Hospital HIV clinic were randomly assigned to either regular adherence counseling, regular counseling plus a calendar, or regular counseling and a treatment assistant. Patients were seen monthly; during these meetings self-reported adherence to treatment was recorded. Disease progression was monitored clinically and immunologically. Of the 621 patients randomized, 312 received regular counseling only, 242 regular counseling and calendars, while 67 had treatment assistants in addition to regular counseling. The mean (SD) follow-up time was 14.5 (4.6) months. During follow-up 20 (3.2%) patients died, and 102 (16.4%) were lost to follow-up; this was similar in all groups. In 94.8% of all visits, patients reported to have adhered to treatment. In only 39 (0.7%) visits did patients report a < or = 95% adherence. There were no differences in adherence (P = 0.573) or differences in CD4 count and weight changes over time in the interventions. Good adherence to ART is possible in resource constrained countries. Persistent adherence counseling in clinic settings by itself may be effective in improving adherence to ART.

Mimicking photosystem II reactions in artificial photosynthesis

In a Swedish collaboration project we make and study synthetic supramolecular systems that mimic the donor side reactions of Photosystem II (PSII). Thus, we have made the first compounds where manganese and tyrosine donors are linked to a Ru(II) photosensitiser, and regenerate the sensitiser after photooxidation. The long-lived, highly oxidising tyrosine radical generated in the light reaction could oxidise a Mn2(III,III) dimer, and the reaction sequence is the first mimic of a single electron transfer of the donor triad of PSII. A detailed study of the tyrosine oxidation in the model system has shown that the oxidation and deprotonation of the tyrosine is a concerted (not consecutive), one-step reaction. This dissociative, proton-coupled electron transfer reaction has an unusually large reorganisation energy, presumably due to the elongation of the tyrosine OH-bond. Because the kinetic data (isotope effects, pH- and temperature dependence) are very similar to data for Mn-depleted PSII, we suggest that the mechanisms are the same at pH7.6, in which a histidine residue is proposed to form a hydrogen bond to TyrZ. We have also been able, for the first time, to oxidise a Ru(II)(bpy)3-linked manganese dimer three steps, from Mn2(II,II) to Mn2(III,IV) in a light-induced reaction. All oxidation steps are driven by the photo-oxidised Ru(III). The accumulation of three oxidising equivalents within a rather narrow potential range suggest that a charge compensating ligand exchange occurs during the oxidation process.
