Adverse human health effects of climate change: an update.

Background: The world is currently facing a process of climate change, which may adversely impact human health in many different ways. The safety of food, water and urban environments is endangered by the consequences of climate change. Sea level and temperature rise, along with more frequent and longer heat waves, represent only a few of the effects of climate change. The increased risk of extreme climate events (e.g., cyclones, droughts and floods) is another serious public health issue. These adverse effects are enhanced in areas and countries not having the capacity to effectively deal with climate change. Study design: We primarily aimed at summarizing the impacts of climate change on public health. A further aim was to identify the most concerning consequences of this phenomenon and the vulnerability factors that amplify the negative effects of climate change. Methods: PubMed and other literature databases were used as literature sources for this narrative review based on the search terms 'climate change' and 'diseases categories' up to January 2024, in order to assess the most recent and relevant scientific evidence about the relation between climate change and public health, identify knowledge gaps and priorities for future research. We also screened the websites of major agencies devoted to human health protection and environmental health. Results and Conclusions: Climate change appears to induce a broad spectrum of generally adverse effects on public health. It may increase the risk of infectious diseases, psychiatric disorders, cancer and other diseases. Currently, we are not effectively counteracting this phenomenon, since pollutant and greenhouse gas emissions have been increasing alongside temperatures. A host of measures are required in order to prevent and fight climate change and related health effects. These include the adoption of a holistic approach and the collaboration of different kinds of expertise in order to design more effective strategies. Special attention should be paid to those who live in disadvantaged countries, and those who are more vulnerable to the adverse health consequences of climate change.

Microbial approaches for pharmaceutical wastewater recycling and management for sustainable development: A multicomponent approach.

A microbial-driven approach for effluent treatment, recycling, and management of Pharmaceutical and Personal Care Products (PPCPs) has been undertaken to mitigate the menace of water contamination. Bioremediation processes are mainly considered the first preference in pharmaceutical wastewater recycling and management. PPCPs are reported as one of the primary sources of emerging contaminants in various water matrices, which raises concern and requires efficient management. Their widespread utilization, persistently high level, and resistance to breaking down make them one of the potentially dangerous compounds causing harm to the ecosystem. Continually increasing PPCPs level PPCPs contaminants in water bodies raised concern for human health as they can produce potential risks with harmful and untoward impacts on our health. PPCPs are composed of multiple diverse compounds used by humans and animals, which include biopharmaceuticals, vitamins and nutritional supplements, antibiotics, counter-prescription drugs, cosmetics products, and unused pharmaceutical products. Personal care products are found to be bioaccumulative, reduce water quality and potentially impact ecological health. However, continual exposure to PPCPs in aquatic organisms, impacts their endocrine function disruption, gene toxicity, and antibiotic resistance. Decreased water quality may result in an outbreak of various water-borne diseases, which could have acute or long-term health complications and may result in an outbreak of various water-borne diseases, which could have acute or long-term effects on public and community health. Polluted water consumption by humans and animals produces serious health hazards and increased susceptibility to water-borne diseases such as carcinogenic organic or inorganic contaminants and infectious pathogens present in water bodies. Many water resource recovery facilities working on various conventional and advanced methods involve the utilization of microbes for filtration and advanced oxidation processes. Therefore, there is an immense need for bioremediation techniques facilitated by mixed cultures of bacteria, algae, and other microbes that can be used as an alternative approach for removing pharmaceutical content from effluent. This review highlights the various sources of PPCPs and their impacts on soil and water bodies, resulting in bioaccumulation. Different techniques are utilized to detect PPCPs, and various control strategies imply controlling, recycling, and managing waste.

Health effects of long-term care insurance on spouses of disabled people: a quasi-experimental study.

BACKGROUND: It is still uncertain whether and how formal long-term care (LTC) systems affect the health status of family members. This paper examines the health effects of long-term care insurance (LTCI) on spouses of disabled people in China. METHODS: The data is from China Health and Retirement Longitudinal Survey (CHARLS), a longitudinal survey of a nationally representative sample of Chinese residents aged 45 or older and their spouses, and China City Statistical Yearbook. Exploiting the regional variation in the implementation of LTCI in the first round of pilot cities in China, a difference-in-difference (DID) strategy is applied to identify the causal effects of LTCI on the health status of spouses of disabled people. We carefully identify the causal effects by controlling for city-level covariates, testing common trends between the treatment and control groups, combining propensity score matching (PSM) with DID, selecting the second round of pilot cities as the control group, controlling for city fixed effects (FE) instead of individual FE, and evaluating selection bias from omitted observable and unobservable factors. RESULTS: The introduction of LTCI in China reduces the number of painful body parts and the self-reported health score significantly, indicating that spouses of disabled people get physical health benefits from LTCI coverage. However, the impact of LTCI on the depression index remains ambiguous and needs to be analyzed further. LTCI improves the physical health status of spouses of disabled individuals mainly through the time reallocation channel, while the impact of the consumption promotion channel has not been verified. Furthermore, the beneficial effects of LTCI on physical health are stronger for spouse caregivers and spouses with lower-level education and lower household income. CONCLUSION: These findings demonstrate that LTCI not only improves the health status of family caregivers by reducing their caregiving burden but also has beneficial health effects on non-caregiver family members. Policy designs of LTCI should emphasize the orientation of home and community-based care services (HCBS), which can not only satisfy the care preferences of disabled individuals, reduce the care burden on family caregivers, promote the health of all family members, but also prevent a large number of disabled individuals from choosing high-cost institutional care and reduce the financial burden of the LTCI Fund.

Synergistic effect of CO2 and PM2.5 emissions from coal consumption and the impacts on health effects.

China put forward that it would strive to achieve the carbon peaking in 2030 and carbon neutrality goals in 2060, which needed realizing the synergistic effect of pollution reduction and CO2 reduction. CO2 and PM2.5 from coal consumption were "homogenous and synchronous" and they had significant synergistic effect. The synergistic reduction of PM2.5 from coal consumption could have impacts on public health. The Logarithmic Mean Divisia Index (LMDI) was adopted to decompose the PM2.5 from coal consumption in China from 2012 to 2017 based on data availability and quantified the synergy. PM2.5 emissions from coal consumption were forecasted in 2030, 2035, 2050 and 2060, and its health effects of PM2.5 were estimated. The main conclusions were: (1) the synergy of CO2 and PM2.5 was the largest contribution factor of PM2.5 from coal consumption. (2) PM2.5 from coal consumption in 2060 would achieve the WHO air quality guidelines. (3) The most health effects economic loss from PM2.5 generated by coal consumption in China was in 2014. The health effects economic loss would have been decreased to negative by 2050. We should reinforce the synergistic effect of CO2 and PM2.5, improve energy efficiency and optimize energy structure to achieve PM2.5 pollution control and reduce health effects economic loss.

Long-term characterization of roadside air pollutants in urban Beijing and associated public health implications.

Road traffic constitutes a major source of air pollutants in urban Beijing, which are responsible for substantial premature mortality. A series of policies and regulations has led to appreciable traffic emission reductions in recent decades. To shed light on long-term (2014-2020) roadside air pollution and assess the efficacy of traffic control measures and their effects on public health, this study quantitatively evaluated changes in the concentrations of six key air pollutants (PM2.5, PM10, NO2, SO2, CO and O3) measured at 5 roadside and 12 urban background monitoring stations in Beijing. We found that the annual mean concentrations of these air pollutants were remarkably reduced by 47%-71% from 2014 to 2020, while the concurrent ozone concentration increased by 17.4%. In addition, we observed reductions in the roadside increments in PM2.5, NO2, SO2 and CO of 54.8%, 29.8%, 20.6%, and 59.1%, respectively, indicating the high effectiveness of new vehicle standard (China V and VI) implementation in Beijing. The premature deaths due to traffic emissions were estimated to be 8379 and 1908 cases in 2014 and 2020, respectively. The impact of NO2 from road traffic relative to PM2.5 on premature mortality was comparable to that of traffic-related PM2.5 emissions. The public health effect of SO2 originating from traffic was markedly lower than that of PM2.5. The results indicated that a reduction in traffic-related NO2 could likely yield the greatest benefits for public health.

Sea Spray Aerosols Contain the Major Component of Human Lung Surfactant.

Marine phytoplankton influence the composition of sea spray aerosols (SSAs) by releasing various compounds. The biogenic surfactant dipalmitoylphosphatidylcholine (DPPC) is known to accumulate in the sea surface microlayer, but its aerosolization has never been confirmed. We conducted a 1 year SSA sampling campaign at the Belgian coast and analyzed the SSA composition. We quantified DPPC at a median and maximum air concentration of 7.1 and 33 pg m-3, respectively. This discovery may be of great importance for the field linking ocean processes to human health as DPPC is the major component of human lung surfactant and is used as excipient in medical aerosol therapy. The natural airborne exposure to DPPC seems too low to induce direct human health effects but may facilitate the effects of other marine bioactive compounds. By analyzing various environmental variables in relation to the DPPC air concentration, using a generalized linear model, we established that wave height is a key environmental predictor and that it has an inverse relationship. We also demonstrated that DPPC content in SSAs is positively correlated with enriched aerosolization of Mg2+ and Ca2+. In conclusion, our findings are not only important from a human health perspective but they also advance our understanding of the production and composition of SSAs.

Indirect health effects of the COVID-19 pandemic in Kenya: a mixed methods assessment.

BACKGROUND: The COVID-19 pandemic and country measures to control it can lead to negative indirect health effects. Understanding these indirect health effects is important in informing strategies to mitigate against them. This paper presents an analysis of the indirect health effects of the pandemic in Kenya. METHODS: We employed a mixed-methods approach, combining the analysis of secondary quantitative data obtained from the Kenya Health Information System database (from January 2019 to November 2020) and a qualitative inquiry involving key informant interviews (n = 12) and document reviews. Quantitative data were analysed using an interrupted time series analysis (using March 2020 as the intervention period). Thematic analysis approach was employed to analyse qualitative data. RESULTS: Quantitative findings show mixed findings, with statistically significant reduction in inpatient utilization, and increase in the number of sexual violence cases per OPD visit that could be attributed to COVID-19 and its mitigation measures. Key informants reported that while financing of essential health services and domestic supply chains were not affected, international supply chains, health workforce, health infrastructure, service provision, and patient access were disrupted. However, the negative effects were thought to be transient, with mitigation measures leading to a bounce back. CONCLUSION: Finding from this study provide some insights into the effects of the pandemic and its mitigation measures in Kenya. The analysis emphasizes the value of strategies to minimize these undesired effects, and the critical role that routine health system data can play in monitoring continuity of service delivery.

Short- and long-term beneficial effects of medicinal mineral water administration.

Medicinal mineral water, being provided by recognized immunosuppressive properties, results useful for treating many pathological conditions. A well-known source of sulfurous and oligomer medicinal mineral waters is located in Caramanico Terme (Pescara, Italy). Caramanico Terme is a small town in the Majella's National Park, and its precious and peculiar environment offers a medicinal mineral water (also known as cures or crenotherapy), that since 1576 is administrated to a large number of patients (around 15,000 per year). However, no scientific conclusions on the efficacy of Caramanico's Terme medicinal mineral water properties are available. Therefore, we have carried out an epidemiological study, enrolling a population of 370 subjects that have received crenotherapy. Such a population has been also compared to a control group of individuals (untreated, N = 287), never undergone any medicinal mineral water administration. Detailing the geomorphological characteristics of Caramanico Terme environment, we have also analyzed the results of the study that showed that pathology-relapses, as well as related manifestations of symptoms and drug employments, were largely reduced after one or more cycles of crenotherapy. On the other hand, a sub-group of subjects receiving crenotherapy for more than 5 years (N = 166) presented a highly reduced prevalence of a large spectrum of pathologies (cardiovascular, inflammatory, neurological and cancer diseases), with respect to an overlapping population (in terms of age and genders) of untreated subjects. We have also clarified the role of aging and long-term effects of medicinal mineral-water administration. Altogether, these data indicated that the clinical employment of Caramanico's Terme medicinal mineral water produces short- as well as long-term beneficial effects, both with respect to the amelioration of life quality of patients and in reducing the probability to develop major disabling pathologies (i.e., cardiovascular, cancer and neurological diseases). Therefore, these data will open novel strategies for a larger application of crenotherapy.

Self-reported Seasonal Symptoms and Diseases and Primary Healthcare Utilization Among Rural Elderly Women in Sylhet District, Bangladesh.

The physical health and conditions of elderly people are challenged by the adverse effects of seasonal variations in sub-tropical countries, including Bangladesh. Research to date does not feature the risk of seasonal changes for primary healthcare infrastructures and practices in supporting elderly women's care, especially in rural areas. This study aims to identify the health effects of seasonal variations that place increased risk of symptoms and diseases on rural elderly women, and to explore the determinants associated with the women's use of healthcare locally. Using a mixed-methods approach, audio-recorded semi-structured interviews including a short survey with sixty-five rural elderly women and eleven healthcare professionals were conducted. Quantitative data were analyzed in SPSS, and a thematic analysis of the qualitative data was facilitated by NVivo. Self-reported health history by rural elderly women identified the prevalence of three major seasonal symptoms: headache (28/43.1%), digestive disorder (27/41.5%), and physical pain (27/41.5%). The prevalence of three symptoms such as nausea, headache and digestive disorder varied significantly (p < 0.05) across the study villages. Of the women, the age group (60-70 years) recorded the highest number of cases (20), followed by age group (71-80 years/15), where the number of cases significantly varied across three seasons (p = 0.021). While 78.5% and 55.4% reported one and two symptoms/diseases respectively, the community clinic visits differed significantly (p = 0.011) among the seasons. The utilization of primary healthcare was low, and marginalization in using healthcare was underpinned by the health system, the poor living conditions of the women, and their reluctance to seek treatment. The findings suggest a need for policy solutions in promoting preventive measures and treatments by strengthening local clinics and on-going health education and training of staff and elderly women.

Water reuse, food production and public health: Adopting transdisciplinary, systems-based approaches to achieve water and food security in a changing climate.

Climate change and population growth are contributing to a growing global freshwater crisis that is exacerbating agricultural water scarcity and compromising food security and public health. In light of these challenges, the increased reliance on nontraditional irrigation water sources, such as reclaimed or recycled water, is emerging as a potentially viable strategy to address water and food insecurity worldwide. This editorial provides an overview of the global need for agricultural water reuse and outlines the environmental and public health impacts associated with this practice. Policy implications, including an emphasis on "One Water" approaches, are discussed. Finally, the editorial leads off a Special Issue that includes a collection of articles reporting on the initial research and extension/outreach findings of CONSERVE: A Center of Excellence at the Nexus of Sustainable Water Reuse, Food and Health, funded by the U.S. Department of Agriculture, National Institute of Food and Agriculture. Taken together, this compilation of articles addresses the overarching theme that transdisciplinary teams are key with regard to moving the science of agricultural water reuse forward to achieve water and food security and advance public health in a changing climate.

Agriculture Occupational Exposures and Factors Affecting Health Effects.

PURPOSE OF REVIEW: Agriculture environments contain a variety of inflammatory aerosols that may increase risk for lung inflammation and disease in exposed individuals. In addition, epidemiological studies have also identified protective effects of rural environments and farming exposures. RECENT FINDINGS: In this review, we will discuss recent literature published since 2016 that investigates the impact of differing agricultural exposures on respiratory health. Discussions include the impact of farming modernization, education, and personal protective equipment usage among workers, timing and duration in mediating lung health outcomes, and population studies investigating the association between exposure and risk for numerous lung diseases.

The health effects of smoking bans: Evidence from German hospitalization data.

This paper studies the short-term impact of public smoking bans on hospitalizations in Germany. It exploits the staggered implementation of smoking bans over time and across the 16 federal states along with the universe of hospitalizations from 2000 to 2008 and daily county-level weather and pollution data. Smoking bans in bars and restaurants have been effective in preventing 1.9 hospital admissions (-2.1%) due to cardiovascular diseases per day, per 1 million population. We also find a decrease by 0.5 admissions (-6.5%) due to asthma per day, per 1 million population. The health prevention effects are more pronounced on sunny days and days with higher ambient pollution levels.

Impact of energy taxation on economy, environmental and public health quality.

This paper argues computable general equilibrium model and assess impact of energy taxation on economy, environmental and public health quality in Tianjin. In order to investigate different energy taxation based on medical cost and labor loss, the computable general equilibrium model integrating with input-output table and social accounting matrix (SAM) was constructed. The medical expense caused by air pollution of Tianjin in 2007 is 396 million yuan and death for 18104 people, which accounted for the total GDP and population 0.754‰ and 1.6‰, respectively. The results show that the enery taxes levy can improve the GDP, but it is only slightly. The energy taxes have adverse impact on energy sector because that the energy cost is increased. The scale of production is reduced, and the capital and labor resources are transferred to low energy consumption low emissions sector. The energy tax levy can reduce air pollutants concentration and improve air environmental quality. The PM10, SO2 and NO2 concentration in the energy taxes 5%-30% was reduced by 0.24%-0.24%, 0.09-0.52% and 0.29%-0.52% respectively. The medical expense has little impact on GDP, but labor loss has a certain effect on GDP. For higher energy taxes rate, the health effects on GDP can reach 0.06%-0.16%. This simultaneous economic and environmental improvement and health effect would thus have positive implications regarding energy taxes of the country.

Child Poverty, Toxic Stress, and Social Determinants of Health: Screening and Care Coordination.

Social determinants of health (SDOH) refer to the social, economic, and physical conditions in which people live that may affect their health. Poverty, which affects nearly 15 million children in the United States, has far-reaching effects on children's physical and mental health. Although it is difficult to change a family's economic circumstances, nurses can play a critical role to address SDOH through screening and effective coordination of care. As nurses, our role is to minimize the effects of SDOH, including poverty, on child health and well-being through our practice, research, and professional education. We present three exemplars of child poverty to demonstrate the impact on child health and well-being and propose a model of care for nurses to assess and address SDOH in the pediatric clinical setting.

Organic Food in the Diet: Exposure and Health Implications.

The market for organic food products is growing rapidly worldwide. Such foods meet certified organic standards for production, handling, processing, and marketing. Most notably, the use of synthetic fertilizers, pesticides, and genetic modification is not allowed. One major reason for the increased demand is the perception that organic food is more environmentally friendly and healthier than conventionally produced food. This review provides an update on market data and consumer preferences for organic food and summarizes the scientific evidence for compositional differences and health benefits of organic compared with conventionally produced food. Studies indicate some differences in favor of organic food, including indications of beneficial health effects. Organic foods convey lower pesticide residue exposure than do conventionally produced foods, but the impact of this on human health is not clear. Comparisons are complicated by organic food consumption being strongly correlated with several indicators of a healthy lifestyle and by conventional agriculture "best practices" often being quite close to those of organic.

A systematic review of possible serious adverse health effects of nicotine replacement therapy.

We conducted a systematic literature review to identify and critically evaluate studies of serious adverse health effects (SAHEs) in humans using nicotine replacement therapy (NRT) products. Serious adverse health effects refer to adverse events, leading to substantial disruption of the ability to conduct normal life functions. Strength of evidence evaluations and conclusions were also determined for the identified SAHEs. We evaluated 34 epidemiological studies and clinical trials, relating NRT use to cancer, reproduction/development, CVD, stroke and/or other SAHEs in patients, and four meta-analyses on effects in healthy populations. The overall evidence suffers from many limitations, the most significant being the short-term exposure (≤12 weeks) and follow-up to NRT product use in most of the studies, the common failure to account for changes in smoking behaviour following NRT use, and the sparse information on SAHEs by type of NRT product used. The only SAHE from NRT exposure we identified was an increase in respiratory congenital abnormalities reported in one study. Limited evidence indicated a lack of effect between NRT exposure and SAHEs for CVD and various reproduction/developmental endpoints. For cancer, stroke and other SAHEs, the evidence was inadequate to demonstrate any association with NRT use. Our conclusions agree with recent statements from authoritative bodies.

Icons for health effects of cigarette smoke: a test of semiotic type.

We sought to identify icons to effectively communicate health harms of chemicals in cigarette smoke. Participants were a convenience sample of 701 U.S. adults. A within-subjects online experiment explored the effects of icon semiotic type: symbolic (arbitrary, most abstract), indexical, and iconic (representative, most concrete). Outcomes were perceived representation, affect toward smoking, elaboration, perceived severity, and perceived effectiveness. For not-easy-to-visualize harms of cancer and addiction, symbolic icons received the highest ratings (all p < .001). For easy-to-visualize symptoms of heart attack/stroke, indexical icons received the highest ratings (all p < .001). For easy-to-visualize harm of reproductive organ damage, the iconic image did best (all p < .001). Icon type often had a larger impact among participants with higher health literacy. Symbolic icons may be most effective for health effects not easily visualized. Iconic or indexical icons may be more effective for health effects attributable to specific body parts or symptoms.

Scientific evidence for health effects attributed to the consumption of probiotics and prebiotics: an update for current perspectives and future challenges.

Probiotics and prebiotics, mainly commercialised as food ingredients and also as supplements, are considered highly profitable niche markets. However, in recent years, the food industry has suffered from a series of health claim restrictions on probiotics and prebiotics in many parts of the world, including those made by the European Food Safety Authority. Therefore, we reviewed the core benefits of probiotic and prebiotic consumption on health. A number of studies have examined the prevention and/or management of intestinal infections, respiratory tract infections, CVD, osteoporosis, urogenital infections, cavities, periodontal disease and halitosis, allergic reactions, inflammatory bowel disease and irritable bowel syndrome and Helicobacter pylori gastric infections. In fact, a deeper understanding of the mechanisms involved in human microbiota and immune system modulation by probiotics and prebiotics relies on continuous efforts to establish suitable biomarkers of health and diseases risk factors for the design of clinical trials required for health claim approval. In spite of the promising results, the performance of large, long-term, well-planned, well-aligned clinical studies is crucial to provide more reliability and a more solid basis for the outcomes achieved and to support the potential use of probiotics and prebiotics in clinical practice.

[New sector of employment--a review of data on nanoproduction, research and development in the field of nanotechnology in Poland]. / Nowy sektor pracowniczy--przeglad danych o nanoprodukcji i dzialalnosci badawczo-rozwojowej w dziedzinie nanotechnologii w Polsce.

Nanotechnology is currently one of the fastest developing areas of science, focusing on the design, manufacture and use of nanomaterials. The term "nanomaterial" means any product made of nanometer-size (1-100 nm) structures. Due to the small size and unique properties of the applied nanomaterials there is a growing interest in their aplication in various fields of industry and science. In Poland, there are very few companies that carry on nanotechnology activities. Research institutes, universities and research units of the Polish Academy of Sciences predominate in these activities.

Combustion By-Products and their Health Effects--combustion engineering and global health in the 21st century: issues and challenges.

The 13th International Congress on Combustion By-Products and their Health Effects was held in New Orleans, Louisiana from May 15 to 18, 2013. The congress, sponsored by the Superfund Research Program, National Institute of Environmental Health Sciences, and National Science Foundation, brought together international academic and government researchers, engineers, scientists, and policymakers. With industrial growth, increased power needs and generation and coal consumption and their concomitant emissions, pernicious health effects associated with exposures to these emissions are on the rise. This congress provides a unique platform for interdisciplinary exchange and discussion of these topics. The formation, conversion, control, and health effects of combustion by-products, including particulate matter and associated heavy metals, persistent organic pollutants, and environmentally persistent free radicals, were discussed during the congress. This review will summarize and discuss the implications of the data presented.
