It has long been thought that respiratory infections are the direct result of acquisition of pathogenic viruses or bacteria, followed by their overgrowth, dissemination, and in some instances tissue ...invasion. In the last decades, it has become apparent that in contrast to this classical view, the majority of microorganisms associated with respiratory infections and inflammation are actually common members of the respiratory ecosystem and only in rare circumstances do they cause disease. This suggests that a complex interplay between host, environment, and properties of colonizing microorganisms together determines disease development and its severity. To understand the pathophysiological processes that underlie respiratory infectious diseases, it is therefore necessary to understand the host-bacterial interactions occurring at mucosal surfaces, along with the microbes inhabiting them, during symbiosis. Current knowledge regarding host-bacterial interactions during asymptomatic colonization will be discussed, including a plausible role for the human microbiome in maintaining a healthy state. With this as a starting point, we will discuss possible disruptive factors contributing to dysbiosis, which is likely to be a key trigger for pathobionts in the development and pathophysiology of respiratory diseases. Finally, from this renewed perspective, we will reflect on current and potential new approaches for treatment in the future.
The intestinal microbiota is important for tolerance induction through mucosal immunological responses. The composition of the gut microbiota of an infant is affected by environmental factors such as ...diet, disease and antibiotic treatment. However, already in utero, these environmental factors can affect the immunological development of the foetus and influence the future gut microbiota of the infant. To investigate the effects of antibiotic treatment of pregnant mothers on the offspring's gut microbiome and diabetes development, we treated non‐obese diabetic (NOD) mice with a cocktail of antibiotics during gestation and the composition of the gut microbiota, diabetes incidence and major gut‐related T lymphocyte populations were investigated in the offspring. We observed a persistent reduction in the general diversity of the gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. In addition, by clustering the present bacterial taxa with principal component analysis, we found a differential clustering of gut microbiota in the offspring from NOD mothers treated with antibiotics during gestation compared with offspring from control mothers. Offspring from NOD mothers treated with antibiotics during gestation also showed some immunological alterations in the gut immune system, which could be related to the diversity of the gut microbiome and influence modulation of diabetes development at 20 weeks. Our data point out maternal derangement of the intestinal microbiota as a potential environmental risk factor for T1D development.
Self-exclusion from gambling is a common method for prevention and harm reduction in hazardous gambling. However, few national self-exclusion programs, involving a large number of gambling operators ...and activities in a country, have been assessed scientifically. This study aimed to examine characteristics of individuals who chose to enroll in a recently introduced (January, 2019) national self-exclusion system in Sweden.
Adults and adolescents (from age 16 and above) were addressed with an online survey sent to members of the web panel of a market survey company (1940 respondents). Psychological distress, previous history of addictive disorders, sociodemographic data, and recent history of gambling patterns and over-indebtedness were recorded. Logistic regression tested associations with self-exclusion, with unadjusted analyses conducted for the sub-group of moderate-risk or problem gamblers.
Four percent reported having self-excluded using the new national self-exclusion system. In logistic regression, self-exclusion was significantly associated with younger age (OR 0.65 0.54-0.79 for increasing age groups) and with the highest level of problem gambling (OR 2.84 1.10-7.37). In moderate-risk or problem gamblers, in unadjusted analyses, younger age (p < 0.05) and psychological distress (p = 0.02) were associated with self-exclusion. In none- or low-risk gamblers, 3% had self-excluded, which was significantly associated with younger age (p < 0.001) and self-reported over-indebtedness (p < 0.001).
In a national, multi-venue online and land-based self-exclusion system, aiming to reduce the harm of problem gambling, self-exclusion is expectedly more common in problem gamblers, but also occurs among people without recent gambling problems. Further efforts may be needed in order to increase gambling self-exclusion in problem gamblers, and research in reasons for self-excluding, even in non-problem gamblers, is needed.
Indebtedness is associated with poor health outcomes, and problem gambling may contribute to indebtedness through consumer credits related to gambling expenses. The assessment of consumers' ...applications for loans may be an opportunity to detect and prevent further problem gambling. The present study analyzed a number of variables including gambling-related transactions and their association with payback failure in 48,197 loans to 20,750 individuals in Sweden. Sums and frequency of gambling deposits or withdrawals generally did not predict failure to pay back loans. Instead, having a loan defaulted at some time was associated with a baseline pattern describing a theoretical loss-of-control gambling pattern (short-term intense gambling), with a higher ratio of gambling deposits or withdrawals per occasion, and with several instances of gambling in close association with a loan. While several group differences were modest, signs of rapid, short-term and intense gambling, rather than gambling itself, may identify risk of payback failure and risk of indebtedness. Implications for early problem-gambling detection and prevention, such as by gambling operators and financial institutes, are discussed and may promote better public health in relation to gambling indebtedness.
Problem gambling is a public health issue affecting both the gamblers, their families, their employers, and society as a whole. Recent law changes in Sweden oblige local and regional health ...authorities to invest more in prevention and treatment of problem gambling. The economic consequences of gambling, and thereby the potential economic consequences of policy changes in the area, are unknown, as the cost of problem gambling to society has remained largely unexplored in Sweden and similar settings.
A prevalence-based cost-of-illness study for Sweden for the year 2018 was conducted. A societal approach was chosen in order to include direct costs (such as health care and legal costs), indirect costs (such as lost productivity due to unemployment), and intangible costs (such as reduced quality of life due to emotional distress). Costs were estimated by combining epidemiological and unit cost data.
The societal costs of problem gambling amounted to 1.42 billion euros in 2018, corresponding to 0.30% of the gross domestic product. Direct costs accounted only for 13% of the total costs. Indirect costs accounted for more than half (59%) of the total costs, while intangible costs accounted for 28%. The societal costs were more than twice as high as the tax revenue from gambling in 2018. Direct and indirect costs of problem gambling combined amounted to one third of the equivalent costs of smoking and one sixth of the costs of alcohol consumption in Sweden.
Problem gambling is increasingly recognized as a public health issue. The societal costs of it are not negligible, also in relation to major public health issues of an addictive nature such as smoking and alcohol consumption. Direct costs for prevention and treatment are very low. A stronger focus on prevention and treatment might help to reduce many of the very high indirect and intangible costs in the future.
Voluntary self-exclusion from gambling is a common harm reduction tool in individuals with a gambling disorder. Previous data have demonstrated that many gamblers breach their own self-exclusion, ...typically through other online services outside the jurisdiction in which they are self-excluded. The present study aimed to carry out a new follow-up measure-similar to previous studies in the same setting-of self-exclusion and its breaching in Sweden, in order to allow for the follow-up assessment of a nationwide, multi-operator self-exclusion system introduced in Sweden in 2019.
A web survey to the web panel of a market survey company addressed 1505 past-year gamblers, who responded to a number of questions about gambling habits, including screening for gambling problems using the Problem Gambling Severity Index and self-exclusion-related items corresponding to previous studies.
Nine percent of past-year gamblers had self-excluded using the Spelpaus service. In logistic regression, self-exclusion was significantly associated with gambling problems, past-year online casino gambling, and absence of online poker gambling. Among self-excluders, 49 percent had ever gambled despite being self-excluded. Among those breaching their self-exclusion, the most common gambling types during self-exclusion were online casino (82 percent), sports betting (47 percent) and lotteries (43 percent).
Self-exclusion remains a popular harm reduction tool against problem gambling, more common than in previous studies, mostly in individuals with recent gambling problems and in online casino gamblers. However, breaching self-exclusion is somewhat more common than in previous research. Online casino represents the most common means of self-exclusion breaching. Policy-making in the area needs to further address the risk of breaching one's self-exclusion and may further address the risk of overseas gambling.
Following the immense impact of the COVID-19 pandemic on health and everyday lives world-wide, people's fear of COVID-19 has been studied in a number of settings using the Fear of COVID scale. In ...Sweden, virus-preventing strategies have differed from comparable countries, with low use of formal lock-down procedures. It is crucial to study correlates of non-compliance with COVID-19 recommendations, and unwillingness to become vaccinated. This study aims to study whether fear of COVID is associated with mental distress and attitudes towards the pandemic, and to study correlates of non-compliance with key anti-COVID recommendations and with reluctancy to vaccination. This anonymous online survey study in web panel participants (N = 1,501) aimed to study a range of behavioral changes during COVID-19. Recommendations and vaccinations reluctancy were analyzed in logistic regressions against socio-demographic data, COVID-19 status, and mental health history. Internal consistency of the Fear of COVID scale was calculated. The Fear of COVID scale had a satisfactory internal consistency (Cronbach-alpha 0.84), and was significantly associated with compliance with all COVID-19 recommendations and with mental health. Non-compliance with recommendations was associated with low fear of disease and younger age, among other variables. Being against vaccination was associated, among other variables, with low fear of disease and with low education. In conclusion, the Fear of COVID scale appears to be associated with key attitudes towards the COVID-19 disease. Anti-virus strategies may need to promote compliance with recommendations in subgroups who feel low fear of disease or who believe not to be in a risk group for severe disease.

Match-fixing, although not a new problem, has received growing attention during the COVID-19 pandemic, which has been reported in the media to have increased the risk of match-fixing events. Gambling ...is a well-documented addictive behavior, and gambling-related fraud, match-fixing, is a challenge to the world of sports. Most research on match-fixing has a judicial or institutional perspective, and few studies focus on its individual consequences. Nevertheless, athletes may be at particular risk of mental health consequences from the exposure to or involvement in match-fixing. The COVID-19 crisis puts a spotlight on match-fixing, as the world of competitive sports shut down or changed substantially due to pandemic-related restrictions. We call for research addressing individual mental health and psycho-social correlates of match-fixing, and their integration into research addressing problem gambling, related to the pandemic and beyond.
Summary
Salivary proteins modulate bacterial colonization in the oral cavity and interact with systemic pathogens that pass through the oropharynx. An interesting example is the opportunistic ...respiratory pathogen Streptococcus pneumoniae that normally resides in the nasopharynx, but belongs to the greater Mitis group of streptococci, most of which colonize the oral cavity. Streptococcus pneumoniae also expresses a serine‐rich repeat (SRR) adhesin, PsrP, which is a homologue to oral Mitis group SRR adhesins, such as Hsa of Streptococcus gordonii and SrpA of Streptococcus sanguinis. As the latter bind to salivary glycoproteins through recognition of terminal sialic acids, we wanted to determine whether S. pneumoniae also binds to salivary proteins through possibly the same mechanism. We found that only a capsule‐free mutant of S. pneumoniae TIGR4 binds to salivary proteins, most prominently to mucin MUC7, but that this binding was not mediated through PsrP or recognition of sialic acid. We also found, however, that PsrP is involved in agglutination of human red blood cells (RBCs). After removal of PsrP, an additional previously masked lectin‐like adhesin activity mediating agglutination of sialidase‐treated RBCs becomes revealed. Using a custom‐spotted glycoprotein and neoglycoprotein dot blot array, we identify candidate glycan motifs recognized by PsrP and by the putative S. pneumoniae adhesin that could perhaps be responsible for pneumococcal binding to salivary MUC7 and glycoproteins on RBCs.
The impact of COVID-19 on gambling behavior and the gambling industry itself has been widely speculated. Prior studies have shown how boredom, social isolation, poor mental health, and financial ...hardships, all of which have been associated with COVID-19, can aggravate problem gambling behaviors in patients with gambling disorders while also luring newcomers. Few studies have used methods other than self-report to assess longitudinal behavioral changes in gambling behavior before versus during the pandemic.
The present study addresses this gap by using an interrupted time series approach on data obtained from the Swedish Gambling Authority measuring taxation on gambling vendors' revenue between January 2019 and November 2021.
March, June, and October 2020 were chosen as interruption points as they correspond to the pandemic's commencement, the return of elite sports, and the second wave of cases in Sweden, respectively. We hypothesized that the pandemic would be associated with both temporary changes for select gambling types and long-term increases in online gambling.
Results revealed the pandemic's onset was associated with transient effects at each point of interruption, as well as long-term upward trends in total gambling and commercial online gambling, excluding horse betting and the state-owned operator for online casinos and betting.
The present study's findings, although consistent with the theory that gambling activity could increase during the pandemic, contradict previous studies that found no changes or a decrease from pre-COVID-19 levels. Findings indicate that the pandemic and Sweden's reaction to it were associated with increased use of some gambling products.
