Engaging Communities in Emerging Infectious Disease Mitigation to Improve Public Health and Safety.

The COVID-19 pandemic highlighted the need for potent community-based tools to improve preparedness. We developed a community health-safety climate (HSC) measure to assess readiness to adopt health behaviors during a pandemic. We conducted a mixed-methods study incorporating qualitative methods (e.g., focus groups) to generate items for the measure and quantitative data from a February 2021 national survey to test reliability, multilevel construct, and predictive and nomologic validities. The 20-item HSC measure is unidimensional (Cronbach α = 0.87). All communities had strong health-safety climates but with significant differences between communities (F = 10.65; p<0.001), and HSC levels predicted readiness to adopt health-safety behaviors. HSC strength moderated relationships between HSC level and behavioral indicators; higher climate homogeneity demonstrated stronger correlations. The HSC measure can predict community readiness to adopt health-safety behaviors in communities to inform interventions before diseases spread, providing a valuable tool for public health authorities and policymakers during a pandemic.

Deaths during the first year of the COVID-19 pandemic: insights from regional patterns in Germany and Poland.

BACKGROUND: Given the nature of the spread of SARS-CoV-2, strong regional patterns in the fatal consequences of the COVID-19 pandemic related to local characteristics such as population and health care infrastructures were to be expected. In this paper we conduct a detailed examination of the spatial correlation of deaths in the first year of the pandemic in two neighbouring countries - Germany and Poland, which, among high income countries, seem particularly different in terms of the death toll associated with the COVID-19 pandemic. The analysis aims to yield evidence that spatial patterns of mortality can provide important clues as to the reasons behind significant differences in the consequences of the COVID-19 pandemic in these two countries. METHODS: Based on official health and population statistics on the level of counties, we explore the spatial nature of mortality in 2020 in the two countries - which, as we show, reflects important contextual differences. We investigate three different measures of deaths: the officially recorded COVID-19 deaths, the total values of excessive deaths and the difference between the two. We link them to important pre-pandemic regional characteristics such as population, health care and economic conditions in multivariate spatial autoregressive models. From the point of view of pandemic related fatalities we stress the distinction between direct and indirect consequences of COVID-19, separating the latter further into two types, the spatial nature of which is likely to differ. RESULTS: The COVID-19 pandemic led to much more excess deaths in Poland than in Germany. Detailed spatial analysis of deaths at the regional level shows a consistent pattern of deaths officially registered as related to COVID-19. For excess deaths, however, we find strong spatial correlation in Germany but little such evidence in Poland. CONCLUSIONS: In contrast to Germany, for Poland we do not observe the expected spatial pattern of total excess deaths and the excess deaths over and above the official COVID-19 deaths. This difference cannot be explained by pre-pandemic regional factors such as economic and population structures or by healthcare infrastructure. The findings point to the need for alternative explanations related to the Polish policy reaction to the pandemic and failures in the areas of healthcare and public health, which resulted in a massive loss of life.

Experimental Analysis of Passenger Comfort with Variable Preloaded Rear Springs on a Low-Cylinder Motorcycle.

The present study contains an experimental analysis of the vibratory response in a low-cylinder engine motorcycle at varying suspension preloads. Three different speed bumps of varying heights were used to subject the motorcycle to different vibrations. The analysis was carried out in three domains: time, frequency, and time-frequency. A triaxial accelerometer was used to measure the vibrations at the seat of the vehicle. The results indicated that the suspension system became more differentiated as the height of the bumps increased. However, for lower bumps, the action of the three spring preloads studied was quite similar. Quantitatively, only the higher bump showed a significant difference between the set preloads. The spectral distribution revealed that the frequency of interest was below 20 Hz for all the studied cases, which is in the same range of human body natural frequencies. The findings of this research can be utilized to enhance the design of low-cost motorcycles, thereby improving the safety and comfort of their drivers and passengers. This study constitutes a significant step towards developing an affordable system capable of gathering sufficient data to support the creation of evidence-based public health policies and propose new transport industry standards based on field measurements.

Improving the health of adolescents: the Nordic countries can help fill the evidence gap.

While in the Nordic countries we have well-developed welfare policies and several structural, statutory measures in place aiming to promote public health, studies from these countries are often absent from systematic reviews of research literature assessing the effects of policy measures designed to promote health. Using adolescent health promotion and efforts related to primary prevention of obesity as an example, this short commentary aims to illustrate the paucity of well-designed studies investigating the effects of public health policies affecting adolescents. This paper argues that the Nordic research community is in a good position to help fill this gap, and to contribute more widely to the international literature on evaluation of policy interventions.

Experiences of long-term care and supportive living residents and families during the COVID-19 pandemic: "It's a lot different for us than it is for the average Joe".

Long-term care and supportive living (LTC/SL) residents are among the most at risk for severe outcomes of COVID-19. As such, early public health measures focused on this population. This study examined the experiences and perspectives of residents and family members of residents living in LTC/SL centres in Alberta, Canada during the COVID-19 pandemic. Between July and October 2020, we conducted semi-structured interviews with 14 residents and 18 family members of residents from 10 centres. Interviews were audio-recorded and analyzed using qualitative content analysis. Analysis revealed 5 categories from resident interviews (Living with Rules and Restrictions; COVID-19 Knowledge and Information; Wellbeing; Centre Operational Response; Criticisms and Suggestions for Improvement) and 6 categories from family interviews (Family Role; Navigating the New Normal; COVID-19 Knowledge and Information; Policy Limitations; Policy Impact; Centre Response). The results highlight the importance of engaging residents and families during pandemic preparation, response, and follow-up evaluation.

Policy determinants of COVID-19 pandemic-induced fatality rates across nations.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) is the most devastating pandemic to affect humanity in a century. In this article, we assessed tests as a policy instrument and policy enactment to contain COVID-19 and potentially reduce mortalities. STUDY DESIGN: A model was devised to estimate the factors that influenced the death rate across 121 nations and by income group. RESULTS: Nations with a higher proportion of people aged 65+ years had a higher fatality rate (P = 0.00014). Delaying policy enactment led to a higher case fatality rate (P = 0.0013). A 10% delay time to act resulted in a 3.7% higher case fatality rate. This study found that delaying policies for international travel restrictions, public information campaigns, and testing policies increased the fatality rate. Tests also impacted the case fatality rate, and nations with 10% more cumulative tests per million people showed a 2.8% lower mortality rate. Citizens of nations who can access more destinations without the need to have a prior visa have a significant higher mortality rate than those who need a visa to travel abroad (P = 0.0040). CONCLUSION: Tests, as a surrogate of policy action and earlier policy enactment, matter for saving lives from pandemics as such policies reduce the transmission rate of the pandemic.

National panorama of adolescent pregnancy in Mexico: lessons learned in a six-year period.

Globally, adolescent pregnancy constitutes a serious public health problem of a multifactorial nature. Specifically for women, it entails various educational, economic and social implications that affect their life project and widen the social gaps in this age group. Furthermore, adolescent girls are more vulnerable because of the health risk involved with pregnancy at a younger age. According to the World Health Organization, "the probability of maternal death is twice as high in adolescents in comparison with women aged between 20 and 30 years, and for those younger than 15 years, the risks are five times higher". In general, adolescents are in great need for education on sexual and reproductive health issues, which should be aimed at increasing information and knowledge about correct use and access to modern contraceptive methods, as well as at demystifying fears and beliefs around their possible side effects. Ensuring proper counseling with trained personnel is equally vital. Public institutions have a social responsibility to support efforts aimed at preventing adolescent pregnancy, based on relevant lines of action and health policies.

En el mundo, el embarazo adolescente constituye un grave problema de salud pública de índole multifactorial. Específicamente para la mujer conlleva diversas implicaciones educativas, económicas y sociales que afectan su proyecto de vida y amplían las brechas sociales en este grupo etario. Asimismo, las adolescentes son más vulnerables por el riesgo en salud que implica un embarazo a corta edad; según la Organización Mundial de la Salud, "la probabilidad de muerte materna es dos veces más en las adolescentes respecto a las mujeres que se encuentran entre los 20 y 30 años de edad, y para las menores de 15 años los riesgos son cinco veces mayores". En general, las y los adolescentes experimentan una gran necesidad de educación en temas sobre salud sexual y reproductiva, la cual debe dirigirse al aumento de información y conocimientos sobre el uso correcto y acceso a métodos anticonceptivos modernos, así como a desmitificar los temores y creencias en torno a sus posibles efectos secundarios. Asegurar una consejería adecuada y con personal capacitado es igualmente vital. Las instituciones públicas tienen la responsabilidad social de respaldar los esfuerzos encaminados a prevenir el embarazo adolescente, con base en las líneas de acción y políticas sanitarias.

Need for public health policies in the elderly population: indicators of aging in a Social Security Institute in Mexico.

INTRODUCTION: An integral diagnosis of population contemplates within its components the population demographic analysis that is indispensable in the formulation of public policies. Population policy has a clearly transversal nature, since all actions in the economic, social, political, cultural, geographical, and obviously, demographic fields, have direct or indirect repercussions on it. OBJECTIVES: To determine the population dynamics and the global growth of the older adult population (OAP) of 60 years and more. MATERIALS AND METHODS: Cross-sectional, retrospective study. The information was obtained from the statistical yearbooks of the institute of security and social services of state workers, Mexico (1999-2015). Several demographic ageing indicators were analyzed. RESULTS: There was a constant increase in percentage points in the proportion of OAP, index of ageing, demographic dependency ratio of old age, global index of dependence, index of dependence of old people, and index of the active population structure (6, 19.2, 15.5, 8.5, 8.2 and 31.2%, respectively). The indicator global index of dependence and masculinity showed a decrease (0.6 and 3.1%, respectively). CONCLUSIONS: Our data provide evidence that suggests modifying and generating public policies according to OAP.

Poverty and Health Disparities: What Can Public Health Professionals Do?

More than a tenth of the U.S. population (13% = 41 million people) is currently living in poverty. In this population, the socioeconomic, cultural, and environmental conditions have detrimental health effects such as higher rates of chronic diseases, communicable illnesses, health risk behaviors, and premature mortality. People living in poverty are also deprived of social, psychological, and political power, leading to continuation of worsening health and chronic deprivation over generations. The health of individuals living in poverty poses greater challenges from policy, practice, and research standpoints. Public health professionals are poised uniquely to be advocates for the marginalized, be the resource persons for health education, implement health promotion programs, and conduct research to understand health effects of poverty and design tailored and targeted public health interventions. In this article, we summarize the opportunities for public health practice with individuals living in poverty.

Sensory impact of lowering sugar content in orange nectars to design healthier, low-sugar industrialized beverages.

The presence of added sugars (AS) in the diet is associated with increased risk of obesity and other chronic diseases. We assessed sensory impact of lowering AS in orange nectar, aiming at new WHO sugar guideline. Ideal sweetness by just-about-right (JAR) tests (60 consumers), difference and rejection thresholds (36 and 35 assessors), and acceptance and sensory profile by Check-all-that-apply (CATA) tests (100 consumers) were performed. JAR test comprised six concentrations of AS from 12% down to 4.5%. Thresholds tests comprised orange nectars at reference sugar concentration (10%) and at lower sugar levels. Acceptance and CATA tests compared reference, ideal sweetness and thresholds concentrations. There were two groups of consumers; one with ideal sweetness lower at 5.5% AS and another with ideal sweetness at standard 10.5% AS. The average ideal sweetness among all consumers was 7.3% AS. The difference threshold from the reference at 10.5% AS was at 8.5% AS and the rejection threshold was 7.2%. Overall acceptance of nectar with 8.5% and 7.2% AS was similar to reference and higher than acceptance of nectar with 5.5%. However, after cluster analysis, nectars with 5.5% AS did not differ from nectars with 8.5% or 7.2% AS, suggesting the possibility of a gradual reduction until 5.5% in the long term. Lowering AS to 7.2% or 5.5% caused significant changes in viscosity, sweet odor, bitterness and sweetness in comparison to the reference concentration. Lowering sugar from 10% to 8.5% did not affect acceptance or sensory attributes, and could be indicated for a first reduction. Results indicate that a gradual reduction to 7.2% and 5.5% would be feasible. Reductions can remove 3150-9450 tons of sugar per year from the Brazilian diet resulting in healthier beverages.

Development of Maryland Local Overdose Fatality Review Teams: A Localized, Interdisciplinary Approach to Combat the Growing Problem of Drug Overdose Deaths.

The Maryland Local Overdose Fatality Review Teams (LOFRTs) are multiagency, multidisciplinary teams that critically analyze individual cases of drug overdose in their jurisdictions to identify preventable risk factors and missed opportunities for intervention, and to make policy and programmatic recommendations to prevent future overdose deaths. Three Maryland LOFRTs were first piloted in early 2014, and became established in law in May of the same year. LOFRTs provide unique opportunities for enhanced interagency collaboration and locally driven prevention efforts. This study describes the process of establishing LOFRTs in Maryland. The experiences and information regarding LOFRTs may help counties in other states combat the growing problem of deaths by drug overdose.

Sub-Saharan African migrants living with HIV acquired after migration, France, ANRS PARCOURS study, 2012 to 2013.

We estimated the proportion of migrants from sub-Saharan Africa who acquired human immunodeficiency virus (HIV) while living in France. Life-event and clinical information was collected in 2012 and 2013 from a random sample of HIV-infected outpatients born in sub-Saharan Africa and living in the Paris region. We assumed HIV infection in France if at least one of the following was fulfilled: (i) HIV diagnosis at least 11 years after arrival in France, (ii) at least one negative HIV test in France, (iii) sexual debut after arrival in France. Otherwise, time of HIV infection was based on statistical modelling of first CD4(+) T-cell count; infection in France was assumed if more than 50% (median scenario) or more than 95% (conservative scenario) of modelled infection times occurred after migration. We estimated that 49% of 898 HIV-infected adults born in sub-Saharan Africa (95% confidence interval (CI): 45-53) in the median and 35% (95% CI: 31-39) in the conservative scenario acquired HIV while living in France. This proportion was higher in men than women (44% (95% CI: 37-51) vs 30% (95% CI: 25-35); conservative scenario) and increased with length of stay in France. These high proportions highlight the need for improved HIV policies targeting migrants.

Modeling approaches to inform travel-related policies for COVID-19 containment: a scoping review and future directions.

BACKGROUND: Travel-related strategies to reduce the spread of COVID-19 evolved rapidly in response to changes in the understanding of SARS-CoV-2 and newly available tools for prevention, diagnosis, and treatment. Modeling is an important methodology to investigate the range of outcomes that could occur from different disease containment strategies. METHODS: We examined 43 articles published from December 2019 through September 2022 that used modeling to evaluate travel-related COVID-19 containment strategies. We extracted and synthesized data regarding study objectives, methods, outcomes, populations, settings, strategies, and costs. We used a standardized approach to evaluate each analysis according to 26 criteria for modeling quality and rigor. RESULTS: The most frequent approaches included compartmental modeling to examine quarantine, isolation, or testing. Early in the pandemic, the goal was to prevent travel-related COVID-19 cases with a focus on individual-level outcomes and assessing strategies such as travel restrictions, quarantine without testing, social distancing, and on-arrival PCR testing. After the development of diagnostic tests and vaccines, modeling studies projected population-level outcomes and investigated these tools to limit COVID-19 spread. Very few published studies included rapid antigen screening strategies, costs, explicit model calibration, or critical evaluation of the modeling approaches. CONCLUSION: Future modeling analyses should leverage open-source data, improve the transparency of modeling methods, incorporate newly available prevention, diagnostics, and treatments, and include costs and cost-effectiveness so that modeling analyses can be informative to address future SARS-CoV-2 variants of concern and other emerging infectious diseases (e.g., mpox and Ebola) for travel-related health policies.

Web-based questionnaire survey for exploring engagement characteristics of advance care planning in Japan: a cross-sectional study.

OBJECTIVE: Definitive promotion of advance care planning (ACP) practices will require policy interventions tailored to the characteristics of the Japanese population and society. However, effective policies for promoting ACP are currently lacking in Japan. This study aimed to explore the characteristics of Japanese people who engaged in ACP activities through a web-based questionnaire survey, which was administered to individuals aged 25-64 years and classified into four occupational categories (non-medical/non-caregiving professionals [general population], physicians, nurses, and caregivers). RESULTS: The total sample size was 1,648, with equal occupational category and age group distributions. Respondents in the general population group were less likely to discuss or document ACP than those in the other groups. Stepwise logistic regression analysis showed a significant difference in the adjusted odds ratio (aOR) of the independent variables of "attended cardiopulmonary resuscitation (CPR) training session(s)" (aOR: 1.93; 95% confidence interval [CI]: 1.18-3.15) and "having experience in performing CPR" (aOR: 2.61; 95% CI: 1.51-4.54) for respondents who discussed ACP with their families. A significant difference was observed in the aOR of the independent variable of "having experience in performing CPR" (aOR: 4.58; 95% CI: 2.30-9.13) for respondents who documented a written record of ACP.

Advances in preventive vaccine development against HTLV-1 infection: A systematic review of the last 35 years.

Introduction: The Human T-lymphotropic virus type 1 (HTLV-1) was the first described human retrovirus. It is currently estimated that around 5 to 10 million people worldwide are infected with this virus. Despite its high prevalence, there is still no preventive vaccine against the HTLV-1 infection. It is known that vaccine development and large-scale immunization play an important role in global public health. To understand the advances in this field we performed a systematic review regarding the current progress in the development of a preventive vaccine against the HTLV-1 infection. Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA®) guidelines and was registered at the International Prospective Register of Systematic Reviews (PROSPERO). The search for articles was performed in PubMed, Lilacs, Embase and SciELO databases. From the 2,485 articles identified, 25 were selected according to the inclusion and exclusion criteria. Results: The analysis of these articles indicated that potential vaccine designs in development are available, although there is still a paucity of studies in the human clinical trial phase. Discussion: Although HTLV-1 was discovered almost 40 years ago, it remains a great challenge and a worldwide neglected threat. The scarcity of funding contributes decisively to the inconclusiveness of the vaccine development. The data summarized here intends to highlight the necessity to improve the current knowledge of this neglected retrovirus, encouraging for more studies on vaccine development aiming the to eliminate this human threat.

Temporal relationship between human and canine visceral leishmaniasis in an urban area in southeastern Brazil: An application of the ARIMAX model.

Visceral leishmaniasis (VL) is a neglected disease of public and animal health importance. With the urbanization of the disease, there is evidence of a temporal correlation between the occurrence of human (HVL) and canine (CVL) visceral leishmaniasis, usually with cases in dogs preceding those in humans. In this context, the objective of this study was to develop a time series model suitable for canine-human transmission of Leishmania infantum. Monthly cases of HVL and CVL from 2006 to 2018 in Belo Horizonte, Minas Gerais, Brazil, were evaluated, and monthly health indicators were calculated for HVL and CVL, i.e., incidence coefficient (HVL_IC) and proportion of seropositive dogs (PSD), respectively. The temporal relationship was evaluated using an autoregressive integrated moving average with exogenous variable (ARIMAX) model for two different periods (January 2006-August 2013 and September 2013-December 2018). During the 13 years studied, 1115 new cases of HVL and 103,358 dogs seropositive for CVL were recorded. HVL_IC and PSD exhibited decreasing trends throughout the first study period (January 2006-August 2013). According to the ARIMAX model adjusted for this period, there was a temporal relationship between HVL_IC and PSD, with HVL_IC being influenced by HVL_IC for the last two and five months and by PSD for the third previous month. For the second study period (September 2013-December 2018), it was not possible to fit an ARIMAX model. This study highlights the improvements made by VL surveillance since 2006 in Belo Horizonte and contributes to a better understanding of the epidemiology of the disease by public health policy-makers, doctors and veterinarians involved in the prevention and control of zoonoses.

Frequency of social participation by types and functional decline: A six-year longitudinal study.

Social participation is effective for preventing functional decline in older people. However, researchers have not fully explored how different frequencies of social participation by type. We aimed to clarify the relationship between the frequency of social participation by type and functional decline. We used data from the Japan Gerontological Evaluation Study, which consists of individuals aged 65 years and older who were not eligible to receive public long-term-care insurance benefits. From 13 municipalities, 51,968 respondents who met the criteria were included in the analysis. We used a sex-stratified Cox proportional hazards model. The outcome was the new incidence of functional decline during a six-year follow-up, and the exposure was the frequency of social participation of one of the following six types: sports, hobbies, volunteering, neighborhood, senior clubs, and industry groups. The frequency was categorized as "never," "a few times a year," "once or twice a month," and "once a week or more." We set non-participation in each activity as the reference, and we adjusted for 12 potential confounders (i.e., sociodemographic and health-related factors). After we adjusted for confounders, participation in sports and hobbies once or twice a month, once a week or more was protectively associated with functional decline. We found a similar association for participation in neighborhood a few times a year. Our findings demonstrate the importance of considering the effects of different types and frequencies of activities when promoting social participation among older people as part of public health policies.

Epidemiological Modeling of the Impact of Public Health Policies on Hepatitis C: Protocol for a Gamification Tool Targeting Microelimination.

BACKGROUND: Hepatitis C is a disease with a strong social component, as its main transmission route is via blood, making it associated with lifestyle. Therefore, it is suitable to be worked on from the perspective of public health policy, which still has a lot of room to explore and improve, contrary to diagnoses and treatments, which are already very refined and effective. OBJECTIVE: An interactive gamified policy tool, designated as Let's End HepC (LEHC), was created to understand the impact of policies related to hepatitis C on the disease's epidemiology on a yearly basis until 2030. METHODS: To this end, an innovative epidemiological model was developed, integrating Markov chains to model the natural history of the disease and adaptive conjoint analysis to reflect the degree of application of each of the 24 public health policies included in the model. This double imputation model makes it possible to assess a set of indicators such as liver transplant, incidence, and deaths year by year until 2030 in different risk groups. Populations at a higher risk were integrated into the model to understand the specific epidemiological dynamics within the total population of each country and within segments that comprise people who have received blood products, prisoners, people who inject drugs, people infected through vertical transmission, and the remaining population. RESULTS: The model has already been applied to a group of countries, and studies in 5 of these countries have already been concluded, showing results very close to those obtained through other forms of evaluation. CONCLUSIONS: The LEHC model allows the simulation of different degrees of implementation of each policy and thus the verification of its epidemiological impact on each studied population. The gamification feature allows assessing the adequate fulfillment of the World Health Organization goals for the elimination of hepatitis C by 2030. LEHC supports health decision makers and people who practice patient advocacy in making decisions based on science, and because LEHC is democratically shared, it ends up contributing to the increase of citizenship in health.
