Conflict and synergy in health promotion partnerships: a Danish case study.

Intersectoral partnerships constitute a central approach in health promotion. By combining different perspectives, knowledge and resources from different sectors, partnerships are important for addressing complex health problems. When successful, intersectoral partnerships create synergy, which is suggested to be a proximal outcome that links partnership functioning to health effects. Nonetheless, partnerships are also difficult and time-consuming and may result in conflicts, hostility and power struggles. Such antagonist outputs are expected to produce negative results. However, conflicts may also be a source of valuable learning. This article explores the relationship between conflict and synergy in health promotion partnerships. The empirical material is derived from an evaluation of a 4-year Danish government partnership program. Data consist of survey data collected from 35 partnerships and in-depth qualitative case studies of 10 partnerships. The analysis was inspired by realist evaluation. The qualitative data were coded, and cases written up. Cross-case analysis was conducted and triangulated with survey data. Surprisingly, disagreements and conflicts of interests between partners were common and associated with synergy creation. Moreover, the partnerships' experiences of synergy were often linked to their attribution of differences rather than to common goals or value congruences. The study identifies that a potential for synergy lays in the productive confrontation between partners different perspectives. Moreover, a key mechanism enabling productive conflicts was inclusive dialog, in which the partners' differences were valued, and all voices were included. The study thus builds on the existing synergy literature and adds nuance to the understanding of conflicts in health promotion partnerships.

The Danish Health and Wellbeing Survey: Study design, response proportion and respondent characteristics.

AIMS: This study aimed to describe the study design and respondent characteristics (including non-response analyses) of the Danish Health and Wellbeing Surveys in 2015 and 2019 and a follow-up survey that was carried out during the COVID-19 pandemic in 2020. METHODS: The Danish Health and Wellbeing Survey is the Danish part of the European Health Interview Survey (EHIS). The samples in 2015 (N=12,000) and 2019 (N=14,000) were both based on a simple random selection of individuals aged ⩾15 years from the Danish Civil Registration System. All individuals from the sample in 2019 who were still alive and living in Denmark were reinvited for a follow-up survey in 2020 (N=13,474). Data in all surveys were collected via self-administered questionnaires (web or paper based). The questionnaires in 2015 and 2019 included the EHIS model questionnaire as well as national questions, whereas the questionnaire in 2020 mainly focused on physical and mental health, employment and working lives, and health behaviour. RESULTS: The overall response proportion declined slightly between 2015 (48.4%) and 2019 (47.4%) but went up to 49.8% in the follow-up survey in 2020. Unit non-response was associated with, for example, male sex, younger age, being unmarried and lower educational level but not with degree of urbanisation. In all, 5000 individuals completed the questionnaire in both 2019 and 2020. CONCLUSIONS: The results are in line with most previous research on non-response in health surveys. However, an association between degree of urbanisation and non-response has been suggested in previous studies. This association was not found in our study.

The impact of non-response weighting in health surveys for estimates on primary health care utilization.

BACKGROUND: Low response rates in health surveys may affect the representativeness and generalizability of results if non-response is systematically related to the indicator of interest. To account for such potential bias, weighting procedures are widely used with an overall aim to obtain less biased estimates. The aim of this study was to assess the impact of applying calibrated weights on prevalence estimates of primary health care utilization among respondents compared to the entire sample of a representative Danish survey of adults aged ≥16 years. METHODS: Registry-based 1-year prevalence data on health care utilization of chiropractor/physiotherapist, dentist and psychologist in 2016 were linked to the entire sample (n = 312 349), including respondents (n = 183 372), from the Danish National Health Survey in 2017. Calibrated weights, which applied information on e.g. sex, age, ethnic background, education and overall health service use were used to assess their impact on prevalence estimates among respondents. RESULTS: Across all included types of health care, weighting for non-response decreased prevalence estimates among respondents, which resulted in less biased estimates. For example, the overall 1-year prevalence of chiropractor/physiotherapist, dentist and psychologist utilization decreased from 19.1% to 16.9%, 68.4% to 62.5% and 1.9% to 1.8%, respectively. The corresponding prevalence in the entire sample was 16.5%, 59.4% and 1.7%. CONCLUSIONS: Applying calibrated weights to survey data to account for non-response reduces bias in primary health care utilization estimates. Future studies are needed to explore the possible impact of weighting on other health estimates.

Trends in dentate status and preventive dental visits of the adult population in Denmark over 30 years (1987-2017).

This study analyzed the trend in self-reported dentate status over 30 years (1987-2017) among Danish adults, the self-reported frequencies of preventive dental visits undertaken annually during the period 1987-2013, and the self-reported use of the 2016 recall scheme for preventive dental check-ups. The impact of social determinants (education, employment, civil status, and ethnic background) on these dental outcome variables in 2017 was explored. Questionnaire data were obtained from the Danish Health and Morbidity Surveys conducted from 1987-2017, and they were analyzed by tri-variate frequency distributions and multivariate analyses. The prevalence of complete tooth loss was 17.7% in 1987 but 3.4% in 2017. The frequency of adults having 20 or more teeth grew markedly from 1987 (65.9%) to 2017 (85.1%). Educational inequality in dentate status persisted over the period. The frequency of preventive dental visits at least annually increased from 1987 to 2013, although visits were less frequent for young people. In 2017, preventive dental check-ups were reported in intervals: less than 12 months (56.4%), 12-18 months (18.9%), 19-24 months (4.8%), and more than 24 months (5.2%). In 2017, dentate status and preventive dental check-ups varied profoundly by social determinants. In conclusion, social policies should be implemented to tackle the persistent inequities in dentate status and public health policies should target Universal Health Coverage.

Pharmacodynamics of propofol and alfaxalone in rattlesnakes (Crotalus durissus).

To characterise the effect of two common induction agents, propofol and alfaxalone, on mean arterial blood pressure (MAP) and heart rate (HR), we equipped 19 adult South American rattlesnakes (Crotalus durissus) with an indwelling arterial catheter approximately 24 h prior to recording of baseline resting values. Then, seven snakes received alfaxalone (15 mg kg-1) intravascularly (IV) through the catheter, while groups two and three (both n = 6) received propofol (15 mg kg-1 IV). The first two groups were not handled, while the group 3 was manually restrained for 2 min for a mock injection of 0.2 ml saline into the ventral tail vein. Baseline HR was similar in all groups and handling caused a significant tachycardia (p = 0.031) in group three. When given IV to undisturbed animals, both propofol and alfaxalone induced a significant increase in HR (p = 0.0022 and p = 0.0045, respectively) lasting approximately 30 min, but with values only significantly exceeding baseline for the first 5 min for propofol and the first 10 min with alfaxalone. Handling caused a significant increase in MAP (p = 0.0313). Propofol did not affect MAP (p = 0.1064), while alfaxalone caused a marked hypertension (although only significant at 2 min; p = 0.031). Manual restraint significantly increases both HR and MAP, which may lead to a masking of true cardiovascular effects of anaesthetic agents.

Cognitive functioning following discontinuation of antipsychotic medication. A naturalistic sub-group analysis from the OPUS II trial.

BACKGROUND: The effect of antipsychotics medication on cognitive functioning in patients diagnosed with schizophrenia is poorly understood. Some studies of second generation antipsychotics indicated that they improved cognitive functioning while other studies have found that they decrease the level of cognitive functioning. METHOD: We included patients with schizophrenia who were in treatment with antipsychotics 1.5 years (baseline) after initiation of treatment and followed them up 3.5 years later (n = 189). At follow-up 60 (32%) had discontinued their antipsychotic treatment and 129 (68%) were still taking antipsychotics. Using the Brief Assessment of Cognition in Schizophrenia (BACS) we assessed cognition at baseline and follow-up. RESULTS: The patients who discontinued their medication had a higher level of cognitive functioning in all domains at baseline, as well as Global cognitive function [mean z-score -1.50 (s.d. 1.24) v. -2.27 (s.d. 1.30), p = 0.00015]. After controlling for relevant confounders those who discontinued antipsychotic medication improved significantly more than those who remained on antipsychotic medication during the course of the follow-up on the Token Motor task [estimated mean change difference -0.46 (95% CI -0.89 to -0.04)], the Speed of Processing Domain [estimated mean change difference -0.38 (95% CI -0.68 to -0.08)] and global cognition [estimated mean change difference -0.36 (95% CI -0.66 to -0.07)]. CONCLUSION: Due to the naturalistic design, we cannot conclude on the direction of the relationship between antipsychotics and cognition. There is no evidence that discontinuation of medication had a negative effect on cognitive functioning. Rather, we found that that discontinuation of medication was associated with better cognitive functioning.

The Danish health and morbidity surveys: study design and participant characteristics.

BACKGROUND: Reliable data from health surveys are essential to describe the status and trends in health indicators by means of information not available from official registers. In Denmark, nationally representative health surveys (the Danish Health and Morbidity Surveys) have been carried out among adults during the past three decades by the Danish National Institute of Public Health, University of Southern Denmark. The aim of the present study is to describe the study design of the three most recent surveys in 2010, 2013, and 2017, including the survey mode and response rates. METHODS: In 2010, 2013, and 2017, the samples (n = 25,000 each) were based on random sampling of individuals aged 16 years or older with a permanent residence in Denmark. A subsample of previously invited respondents was also re-invited in subsequent survey waves. Data were collected through self-administered questionnaires, yet with a concurrent mixed-mode approach, allowing for the invited individuals to complete either a web questionnaire or an identical paper questionnaire. In 2010 and 2013, survey invitations were sent by regular postal mail, whereas a secure electronical mail service, Digital Post, was used to invite the majority (90.1%) of the sample in 2017. RESULTS: The overall response rate decreased from 60.7% in 2010 to 57.1% in 2013 and 56.1% in 2017. Between 2010 and 2017 the response mode distribution for the web questionnaire increased markedly from 31.7 to 73.8%. The largest increase in the proportion which completed the web questionnaire was found in the oldest age group. CONCLUSIONS: Data from the Danish Health and Morbidity Surveys reveal an increasing proportion of the respondents to complete web questionnaires instead of paper questionnaires. Even though the response rate remained relatively stable in 2017, declining response rates is a major concern in health surveys. As the generalizability to the Danish population may be compromised by a low response rate, efforts to increase the response rate or keep it stable are crucial in future surveys. Thus, efforts should be made to ensure convenience and feasibility in relation to access to and the completion of survey (web) questionnaires.

Neighbour noise annoyance is associated with various mental and physical health symptoms: results from a nationwide study among individuals living in multi-storey housing.

BACKGROUND: Noise exposure is considered a stressor that may potentially exert negative health effects among the exposed individuals. On a population basis, the most prevalent and immediate response to noise is annoyance, which is an individually experienced phenomenon that may activate physiological stress-responses and result in both physical and mental symptoms. Health implications of traffic noise have been investigated thoroughly, but not of neighbour noise. The aim of the present study was to examine the associations between neighbour noise annoyance and eight different physical and mental health symptoms. METHODS: Cross-sectional data from the Danish Health and Morbidity Survey 2017 were used. The present study included a random sample of 3893 adults living in multi-storey housing. Information on neighbour noise annoyance and various health symptoms (e.g. pain in various body parts, headache, sleeping problems, depression, and anxiety) during the past two weeks was obtained by self-administered questionnaires. The question on neighbour noise annoyance and health symptoms, respectively, had three possible response options: 'Yes, very annoyed/bothered', 'Yes, slightly annoyed/bothered', 'No'. The associations between neighbour noise annoyance and very bothering physical and mental health symptoms were investigated using multiple logistic regression models. RESULTS: Being very annoyed by neighbour noise was significantly associated with higher odds of being very bothered by all eight health symptoms (adjusted OR = 1.73-3.32, all p-values < 0.05) compared to individuals not annoyed by noise from neighbours. Statistically significant interactions were observed between sex and two of the eight health symptoms. Among women, a strong association was observed between neighbour noise annoyance and being very bothered by pain or discomfort in the shoulder or neck, and in the arms, hands, legs, knees, hips or joints. Among men, no associations were observed. CONCLUSIONS: Based on the findings from this study, neighbour noise annoyance is strongly associated with eight different physical and mental health symptoms. Future studies are encouraged to 1) determine the direction of causality using a longitudinal design, 2) explore the biological mechanisms explaining the sex-specific impact of neighbour noise annoyance on symptoms of musculoskeletal pain or discomfort and the other outcomes as well.

Alcohol's harms to others: the self-rated health of those with a heavy drinker in their lives.

BACKGROUND: Studies have examined the self-rated health (SRH) of the drinker, but only few have examined the health of those affected by a heavy drinker. This Nordic study aimed to examine the association between exposure to heavy drinkers and SRH. METHODS: Data come from surveys from the five Nordic countries that participated in the Reducing Alcohol-Related Harm Standardized European Survey in 2015 (n = 7065 aged 18-64 years). Variables included a five-point Likert-scale question on one's SRH, a question on whether the respondent knew a heavy drinker in the last 12 months, and covariates. The 'fair', 'poor' and 'very poor' response categories were combined and are referred to as poor SRH. Multiple logistic regression models were used to examine the relationship between knowing a heavy drinker and one's SRH. RESULTS: Country-pooled adjusted analyses showed a significant relationship between knowing (and being negatively affected by) a heavy drinker and poor SRH [odds ratios (OR) = 1.39, 95% confidence intervals (CI): 1.02-1.89 for heavy drinker in household; OR = 1.23, 95% CI: 1.07-1.42 for other known heavy drinker, compared to not knowing a heavy drinker or knowing a heavy drinker, but not being negatively affected]. A graded relationship appeared such that increasing proximity of the known heavy drinker increased likelihood to report poor SRH. CONCLUSION: Knowing and being negatively affected by someone close who drinks heavily increases the likelihood of reporting poor SRH. These results have implications for public health messaging regarding the well-being of relatives of heavy drinkers.

Neighbour and traffic noise annoyance: a nationwide study of associated mental health and perceived stress.

Background: Noise exposure is a well-known risk factor for multiple adverse health effects. Annoyance is the most prevalent response to environmental noise and may result in negative emotional responses, including poor mental health and high levels of perceived stress. The aim of this study was to investigate the association between neighbour and traffic noise annoyance, and mental health and perceived stress. Methods: Data were derived from the Danish Health and Morbidity surveys in 2010 and 2013. The study was based on a random sample of the adult population in Denmark living in multistorey housing (n = 7090). Information on neighbour and traffic noise annoyance during the past 2 weeks, and mental health and perceived stress, using Short Form-12 and Perceived Stress Scale instruments, respectively, was obtained by means of self-administered questionnaires. Multiple logistic regression models were used to examine the associations between noise annoyance and poor mental health, and high perceived stress levels, respectively. Results: Those who reported being very annoyed by neighbour noise had 2.34 [95% confidence interval (CI): 1.83-2.99] times higher odds of having poor mental health and 2.78 (95% CI: 2.25-3.43) times higher odds to experience a high level of perceived stress than individuals not annoyed by noise from neighbours. Similar associations were observed with traffic noise annoyance. Conclusion: The results from this study indicate that there is a strong relationship between noise annoyance and poor mental health and high levels of perceived stress among individuals living in multistorey housing in Denmark. Future studies are needed to determine the direction of causality.

CARDIOVASCULAR EFFECTS OF ALFAXALONE AND PROPOFOL IN THE BULLFROG, LITHOBATES CATESBEIANUS.

Alfaxalone is becoming a popular anesthetic for nonmammalian vertebrates, but the physiological effects of its administration remain largely unknown in these taxa. Therefore, the cardiovascular responses to a clinically relevant dose of alfaxalone (10 mg/kg) are reported in the bullfrog ( Lithobates catesbeianus), following intramuscular (IM) and intravascular (IV) administration (via a femoral artery catheter) and compared with an IV dose of propofol, another parenteral GABA (γ-aminobutyric acid) agonist in common veterinary use as an induction agent. Heart rate (HR) and mean arterial blood pressure (MAP) (assessed by direct measurement from the catheter) are reported from under undisturbed conditions to assess both the direct effects of the drugs and the interaction with the stress of handling associated with IM injection of alfaxalone where IM administration is possible. Alfaxalone caused HR to increase significantly for over 45 min in both groups from a baseline of approximately 30 beats/min. This was significantly different from the lack of significant HR response on the IV administration of propofol. MAP increased in the peri-injection period with both routes of administration for alfaxalone but after IV use decreased significantly from 10 min following administration. Propofol did not affect blood pressure after 5 min from injection. Assessment of immobilization following intramuscular injection of alfaxalone in a pilot study was in accordance with the literature, as it provided no antinociception as a sole agent but did produce sedation and loss of righting reflex.

When local anesthesia becomes universal: Pronounced systemic effects of subcutaneous lidocaine in bullfrogs (Lithobates catesbeianus).

Sodium channel blockers are commonly injected local anesthetics but are also routinely used for general immersion anesthesia in fish and amphibians. Here we report the effects of subcutaneous injection of lidocaine (5 or 50mgkg-1) in the hind limb of bullfrogs (Lithobates catesbeianus) on reflexes, gular respiration and heart rate (handled group, n=10) or blood pressure and heart rate via an arterial catheter (catheterized group n=6). 5mgkg-1 lidocaine did not cause loss of reflexes or change in heart rate in the handled group, but was associated with a reduction in gular respiratory rate (from 99±7 to 81±17breathsmin-1). 50mgkg-1 lidocaine caused a further reduction in respiratory rate to 59±15breathsmin-1, and led to a progressive loss of righting reflex (10/10 loss by 40min), palpebral reflex (9/10 loss at 70min), and contralateral toe pinch withdrawal (9/10 loss at 70min). Reflexes were regained over 4h. Systemic sedative effects were not coupled to local anti-nociception, as a forceps pinch test at the site of injection provoked movement at the height of the systemic effect (tested at 81±4min). Amphibians are routinely subject to general anesthesia via exposure to sodium channel blockers such as MS222 or benzocaine, however caution should be exercised when using local injectable lidocaine in amphibians, as it appears to dose-dependently cause sedation, without necessarily preventing local nociception for the duration of systemic effects.

Assessing the influence of mechanical ventilation on blood gases and blood pressure in rattlesnakes.

OBJECTIVE: To characterize the impact of mechanical positive pressure ventilation on heart rate (HR), arterial blood pressure, blood gases, lactate, glucose, sodium, potassium and calcium concentrations in rattlesnakes during anesthesia and the subsequent recovery period. STUDY DESIGN: Prospective, randomized trial. ANIMALS: Twenty one fasted adult South American rattlesnakes (Crotalus durissus terrificus). METHODS: Snakes were anesthetized with propofol (15 mg kg(-1)) intravenously, endotracheally intubated and assigned to one of four ventilation regimens: Spontaneous ventilation, or mechanical ventilation at a tidal volume of 30 mL kg(-1) at 1 breath every 90 seconds, 5 breaths minute(-1), or 15 breaths minute(-1). Arterial blood was collected from indwelling catheters at 30, 40, and 60 minutes and 2, 6, and 24 hours following induction of anesthesia and analyzed for pH, PaO2, PaCO2, and selected variables. Mean arterial blood pressure (MAP) and HR were recorded at 30, 40, 60 minutes and 24 hours. RESULTS: Spontaneous ventilation and 1 breath every 90 seconds resulted in a mild hypercapnia (PaCO2 22.4 ± 4.3 mmHg [3.0 ± 0.6 kPa] and 24.5 ± 1.6 mmHg [3.3 ± 0.2 kPa], respectively), 5 breaths minute(-1) resulted in normocapnia (14.2 ± 2.7 mmHg [1.9 ± 0.4 kPa]), while 15 breaths minute(-1) caused marked hypocapnia (8.2 ± 2.5 mmHg [1.1 ± 0.3 kPa]). Following recovery, blood gases of the four groups were similar from 2 hours. Anesthesia, independent of ventilation was associated with significantly elevated glucose, lactate and potassium concentrations compared to values at 24 hours (p < 0.0001). MAP increased significantly with increasing ventilation frequency (p < 0.001). HR did not vary among regimens. CONCLUSIONS AND CLINICAL RELEVANCE: Mechanical ventilation had a profound impact on blood gases and blood pressure. The results support the use of mechanical ventilation with a frequency of 1-2 breaths minute(-1) at a tidal volume of 30 mL kg(-1) during anesthesia in fasted snakes.

Ultrasound imaging of the anterior section of the eye of five different snake species.

BACKGROUND: Nineteen clinically normal snakes: six ball pythons (Python regius), six Burmese pythons (Python bivittatus), one Children's python (Antaresia childreni), four Amazon tree boas (Corallus hortulanus), and two Malagasy ground boas (Acrantophis madagascariensis) were subjected to ultrasound imaging with 21 MHz (ball python) and 50 MHz (ball python, Burmese python, Children's python, Amazon tree boa, Malagasy ground boa) transducers in order to measure the different structures of the anterior segment in clinically normal snake eyes with the aim to review baseline values for clinically important ophthalmic structures. The ultrasonographic measurements included horizontal spectacle diameter, spectacle thickness, depth of sub-spectacular space and corneal thickness. For comparative purposes, a formalin-fixed head of a Burmese python was subjected to micro computed tomography. RESULTS: In all snakes, the spectacle was thinner than the cornea. There was significant difference in spectacle diameter, and spectacle and corneal thickness between the Amazon tree boa and the Burmese and ball pythons. There was no difference in the depth of the sub-spectacular space. The results obtained in the Burmese python with the 50 MHz transducer were similar to the results obtained with micro computed tomography. Images acquired with the 21 MHz transducer included artifacts which may be misinterpreted as ocular structures. CONCLUSIONS: Our measurements of the structures in the anterior segment of the eye can serve as orientative values for snakes examined for ocular diseases. In addition, we demonstrated that using a high frequency transducer minimizes the risk of misinterpreting artifacts as ocular structures.

Implications of the decline in adolescent drinking on the experience of alcohol-related consequences in the Nordic countries: A study based on data from the ESPAD project.

Aims: The aim of this study was to investigate: (1) whether self-reported acute alcohol-related consequences among adolescents in the Nordic countries have declined in concert with the decline in alcohol consumption; (2) whether the relationship between alcohol consumption and alcohol-related consequences has strengthened; and (3) whether the decline in alcohol-related consequences can be attributed to the decline in alcohol consumption. Methods: Data are from the European School Survey Project on Alcohol and Other Drugs (ESPAD) cross-sectional surveys in 2007, 2011 and 2015. Participants were students aged 15-16 years in 2007 (n = 16,035), 2011 (n = 14,765) and 2015 (n = 13,517). Alcohol consumption variables included lifetime and 12-month alcohol use, volume ethanol at last drinking occasion and heavy episodic drinking in the past 30 days. Self-reported acute alcohol-related consequences were measured as a sum index of experiencing the following at least once within the last 12 months: (1) an accident or injury; (2) being victimised by robbery or theft; or (3) had trouble with the police. Results: For all alcohol indicators, adolescent alcohol use decreased between 2007 and 2015. The highest prevalence estimates were found in Denmark, and here only the number of current drinkers decreased significantly. In addition, a decreasing trend in self-reported acute alcohol-related consequences was observed. We did not find a strengthening of the alcohol consumption consequences association from 2007 to 2015, except in Iceland. When all surveys were combined, the decrease in alcohol-related consequences could be explained by a decrease in alcohol consumption. Conclusions: Overall, adolescents aged 15-16 years exhibited decreasing trends in both alcohol consumption, less markedly in Denmark, and in our sum index of alcohol-related consequences between 2007 and 2015. Except for Iceland, we found no support for a strengthening of the alcohol-consequences association with declining drinking among adolescents.

A scoping review on the effects of Varroa mite (Varroa destructor) on global honey bee decline.

Arguably the most ecologically and economically valuable pollinators worldwide, honey bees play a significant role in food production and enrich biodiversity through pollination. Varroa destructor is an invasive ectoparasitic mite that attacks and feeds on European honey bee, Apis mellifera. Because literature on the effectiveness and sustainability of various treatment modalities available for Varroa mite control in honey bee colonies are scattered, this scoping review was conducted to serve as a guiding document with a focus on: (1) identifying the detrimental impact Varroa mites have on the European honey bee; (2) determining current methods for Varroa mite control and their limitations; (3) examining current market landscape and key players in the pesticide market; and (4) identifying opportunities for more sustainable Varroa mite control methods. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, 397 articles published between 1998 and 2022 were screened; of which 65 articles were retained using inclusion/exclusion criteria, which were systematically analyzed in-depth, information extracted, and included in this scoping review. The results suggest that Varroa mites are one of the predominant causes of global honey bee decline as they lack natural resistance to Varroa mites, thereby negatively affecting honey bee reproduction and immunity, killing broods, and transmitting pathogenic viruses to colonies. Further, our findings suggest that: apiarists have many options for Varroa control, but no method has proven to be effective, safe and nonpersistent in the environment; adoption of nano-pesticides and development of sustainable alternatives to traditional pesticides are key drivers for growing pesticide market; and nano-pesticides may have potential to serve as an effective, safe and non-ecopersistent pesticide for Varroa mite and associated virus control. In conclusion, this review highlights an unmet need for effective and sustainable control strategies and tools for Varroa mite and virus control.

Health and Well-Being in Older Adults With a Surgically Closed or an Unrepaired Ventricular Septal Defect.

Background Older adults with a congenital ventricular septal defect (VSD) recently exhibited reduced heart rate variability and exercise capacity. It is unknown whether these findings affect health-related quality of life. Methods and Results Adults with VSDs and healthy controls, all concurrently included as part of another clinical study, completed the Danish National Health Survey questionnaire. Questionnaire data distributed to the general population were included and matched 10:1 with patients. Thirty patients with surgically closed VSDs (mean±SD age, 51±8 years), 300 adults from the general population (mean±SD age, 50±8 years), and 30 controls (mean±SD age, 51±9 years), as well as 30 patients with unrepaired VSDs (mean±SD age, 55±11 years), 300 adults from the general population (mean±SD age, 55±12 years), and 30 controls (mean±SD age, 55±10 years) completed the questionnaire. Educational level, social relations, and physical activity were comparable between groups. A larger proportion of patients with unrepaired VSDs compared with the general population experienced migraine (47% versus 24%; P=0.04), whereas more patients with surgically closed VSDs were affected by depression (13% versus 4%; P=0.02). For health-related quality of life, patients with surgically closed VSDs reported lower physical functioning (P<0.01), physical component summary (P<0.01), general health perception (P<0.01), and higher stress score (P=0.03) compared with the general population and healthy controls. Patients with unrepaired VSDs reported lower scores on physical functioning (P=0.03), bodily pain (P<0.01), and mental health (P=0.02), and a higher stress score (P=0.03), than controls. Conclusions Older patients with VSDs report lower self-perceived physical functioning, lower general health, and higher stress levels, all in line with previous findings, like lower exercise capacity and dysfunctional cognitive abilities, in adults with VSDs. Incessant follow-up is paramount, as neither successfully closed nor hemodynamically insignificant VSD is equivalent with untroubled healthy aging.

Agreement between self-reported diseases from health surveys and national health registry data: a Danish nationwide study.

BACKGROUND: Agreement may be low when comparing self-reported diseases in health surveys with registry data. The aim of the present study was to examine the agreement between seven self-reported diseases among a representative sample of Danish adults aged ≥16 years and data from medical records. Moreover, possible associations with sociodemographic variables were examined. METHODS: Nationally representative data on self-reported current or previous diabetes, asthma, rheumatoid arthritis, osteoporosis, myocardial infarction, stroke and cancer, respectively, were derived from the Danish National Health Survey in 2017 (N=183 372). Individual-level data were linked to data on the same diseases from medical records in registries. Logistic regression models were used to explore potential associations between sociodemographic variables and total agreement. RESULTS: For all included diseases, specificity was >92% and sensitivity varied between 66% (cancer) and 95% (diabetes). Negative predictive value (NPV) was >96% for all diseases and positive predictive value (PPV) varied between 13% (rheumatoid arthritis) and 90% (cancer). Total agreement varied between 91% (asthma) and 99% (diabetes), whereas the kappa value was lowest for rheumatoid arthritis (0.21) and highest for diabetes (0.88). Sociodemographic variables were demonstrated to be significantly associated with total agreement for all diseases, with sex, age and educational level exhibiting the strongest associations. However, the directions of the associations were inconsistent across diseases. CONCLUSION: Overall, self-reported data were accurate in identifying individuals without the specific disease (ie, specificity and NPV). However, sensitivity, PPV and kappa varied greatly between diseases. These findings should be considered when interpreting similar results from surveys.

Trends in social inequality in mortality in Denmark 1995-2019: the contribution of smoking- and alcohol-related deaths.

BACKGROUND: During the past decades, social inequality in mortality has increased in several countries, including Denmark. Modifiable risk factors, such as smoking and harmful alcohol consumption, have been suggested to moderate the association between socioeconomic position and health-related outcomes. The present study aims to investigate the contribution of smoking- and alcohol-related deaths to the trends in educational inequality in mortality in Denmark 1995-2019 among individuals aged 30-74 years. METHODS: Nationwide data on mortality and highest attained educational level divided into quartiles were derived from administrative registers. Alcohol-related mortality was directly estimated using information on alcohol-related deaths from death certificates. Smoking-related mortality was indirectly estimated using the Peto-Lopez method. The contribution of smoking- and alcohol-related deaths to the social inequality gap in mortality 1995-2019 was calculated. RESULTS: Alongside a decrease in all-cause mortality in Denmark 1995-2019, absolute differences in the mortality rate (per 100 000 person-year) between the lowest and the highest educational quartile increased from 494 to 607 among men and from 268 to 376 among women. Among both men and women, smoking- and alcohol-related deaths explained around 60% of the social inequality in mortality and around 50% of the increase in mortality inequality. CONCLUSION: Smoking and harmful alcohol consumption continue to be important risk factors and causes of social inequality in mortality, with around half of the increase in Denmark 1995-2019 being attributable to smoking- and alcohol-related deaths. Future healthcare planning and policy development should aim at reducing social inequality in modifiable health risk behaviours and their negative consequences.

Self-reported reasons for discontinuation or continuation of antipsychotic medication in individuals with first-episode schizophrenia.

AIM: Many individuals with schizophrenia discontinue initially prescribed antipsychotics. Knowledge on reasons for discontinuation among individuals with first-episode schizophrenia is sparse. We aimed to describe reasons for discontinuation and continuation, differences between individuals discontinuing and continuing, and factors predicting reasons for discontinuation or continuation. METHODS: This was a prospective cohort study with a post hoc design. Individuals with first-episode schizophrenia were included from early intervention teams in Denmark from 2009-2012. Sociodemographic and clinical variables were collected at baseline and reasons for discontinuation and continuation of antipsychotics were assessed at 3.5-year follow-up. RESULTS: Among 215 patients, 76 reported reasons for discontinuation and 139 for continuation. The most frequent reasons for discontinuation were "side effects" and "patient believed he/she no longer needed the medication because he/she was now better". The most frequent reasons for continuation were "benefits for positive symptoms" and "another person told them to". Individuals who discontinued antipsychotics were at baseline younger, had longer DUP, less negative symptoms, better social function, lower compliance, higher self-belief of coping, and fewer used antipsychotics compared to those continuing antipsychotics. CONCLUSIONS: The effect of antipsychotics is the main reason to continue, whereas side effects were the main reason to discontinue. Knowledge of reasons to discontinue or continue is helpful in shared decision-making, identifying individuals with high odds of discontinuation, improving adherence, and helping with safe discontinuation.
